National indicators for quality of drug therapy in older persons: the Swedish experience from the first 10 years

Treatment of Pain in Cirrhosis: Advice to Caregivers of Those with Rock Livers

PURPOSE

When one considers the significant role of the liver in medication absorption and metabolism, clinicians must appreciate the important ramifications for medication dosing and monitoring in patients with cirrhosis. For many medications, dose adjustments may be necessary to minimize toxicities or avoid adverse effects from drug accumulation. Clinicians could be well served if they can understand in some detail how pharmacokinetic properties are altered in cirrhosis.

METHODS

A PubMed search of the English medical literature starting with 1980 using keywords cirrhosis, pain management, and analgesics was performed, and additional papers were found using references from the first round of papers.

FINDINGS

Patients with cirrhosis often have significant reductions in first-pass metabolism, altered volumes of distribution, and marked reductions in both renal and hepatic elimination of drugs. These factors may contribute to much higher levels of drug exposure compared to the general population. In terms of drug dosing, FDA labeling is often ambiguous and even incongruous with observed pharmacokinetic changes.

IMPLICATIONS

This article may provide guidance for clinicians to optimize pain management in people living with cirrhosis.

KEY MESSAGE

Current FDA labeling for dosing analgesic drugs in patients with cirrhosis is either vague or not consistent with findings from newer pharmacokinetic research. With this review, we hope to provide insight and guidance to clinicians on how to dose-adjust medications commonly utilized in pain management in these patients.

Reliability and validity of the Swedish indicator 'Drugs that should be avoided in older people'-an appraisal of a set of potentially inappropriate medications

PURPOSE

To analyse the reliability and validity of the Swedish indicator 'Drugs that should be avoided in older people'.

METHODS

From a previous study that included consecutive primary care patients ≥ 65 years of age, all patients ≥ 75 years of age were analysed. Two physicians independently screened their medication lists and medical records, applying the Swedish indicator which includes potentially inappropriate medications (PIMs): long-acting benzodiazepines, drugs with anticholinergic action, tramadol, propiomazine, codeine, and glibenclamide. The clinical relevance of identified PIMs was independently assessed. Thereafter, the physicians determined in consensus whether some medical action related to the drug treatment was medically justified and prioritised before the next regular visit. If so, the drug treatment was considered inadequate, and if not, adequate.

RESULTS

A total of 1,146 drugs were assessed in 149 patients (75‒99 years, 62% female, 0‒20 drugs per patient). In 29 (19%) patients, at least one physician identified ≥ 1 PIM according to the indicator at issue; 24 (16%) patients were concordantly identified with ≥ 1 such PIM (kappa: 0.89). Of 26 PIMs concordantly identified, the physicians concordantly assessed four as clinically relevant and 12 as not clinically relevant (kappa: 0.17). After the consensus discussion, six (4%) patients had ≥ 1 PIM according to the studied indicator that merited action. Using the area under the receiver operating characteristic (ROC) curve, the indicator did not outperform chance in identifying inadequate drug treatment: 0.56 (95% confidence interval: 0.46 to 0.66).

CONCLUSION

The Swedish indicator has strong reliability regarding PIM detection but does not validly reflect the adequacy of drug treatment.

[Use of antipsychotics in patients with dementia in Spain: Comparison with prescription of acetylcholinesterase inhibitors and memantine and analysis of associations]

OBJECTIVE

We have analyzed the prevalence of antipsychotics in patients with dementia in Spain, their age distribution and the influence of treatment with IACEs and memantine on their prescription.

METHOD

Descriptive, retrospective and cross-sectional study of the 2017 BIFAP database in over 65 years of age with dementia. Prescriptions of antipsychotics, IACEs and memantine were collected. For antipsychotics were also collected, the duration of treatment and time from dementia diagnosis to prescription.

RESULTS

A total of 1,327,792 subjects were retrieved, 89,464 (6.73%) with dementia. Antipsychotics were prescribed in 31.76%; by frequency: quetiapine (58.47%), risperidone (21%) and haloperidol (19.34%). Prescriptions of IACEs and memantine were clustered in those younger than 84 years and antipsychotics in those older than 85 (P<.001). Antipsychotics were maintained for a mean of 1174.5 days. In 26.4% of cases they were prescribed alone, OR 0.61 (95% CI: 0.59-0.62), in 35.85% associated with IACEs, OR 1.26 (95% CI: 1.22-1.30) and in 42.4% with memantine, OR 1.69 (95% CI: 1.62-1.78) (P<.000). From the diagnosis of dementia, 461 days (±1576.5) elapsed when isolated drugs were prescribed; 651 days (±1574.25) associated with IACEs and 1224 (±1779) with memantine.

CONCLUSIONS

One third of patients with dementia were prescribed antipsychotics, mostly atypical, more frequently in those older than 85 years and for prolonged periods. IACEs and memantine were associated with the risk of antipsychotic prescription, but paradoxically, with prolonged time to onset.

Causes of death after first time venous thromboembolism

BACKGROUND

Causes of death after first time community-acquired venous thromboembolism (VTE) diagnosed in unselected patients at the emergency department (ED) was investigated.

MATERIALS AND METHODS

The study consists of all patients > 18 years of age who had a visit for any medical reason to any of 5 different ED in Stockholm County, Sweden from 1st January 2016 to 31st December 2017. We have identified all patients with a first registered incident VTE; deep vein thrombosis (DVT) and/or pulmonary embolism (PE) during the study period. Cox regression models were used to estimate hazards ratios (HR) with 95% confidence intervals (CIs) for all-cause mortality and cause-specific death in patients with DVT or PE using all other patients as the reference group.

RESULTS

In total, 359,884 patients had an ED visit during the study period of whom about 2.1% were diagnosed with VTE (DVT = 4,384, PE = 3,212). The patients with VTE were older compared to the control group. During a mean follow up of 2.1 years, 1567 (21%) and 23,741(6.7%) patients died within the VTE and reference group, respectively. The adjusted risk of all-cause mortality was nearly double in patients with DVT (HR 1.7; 95% CI, 1.5-1.8) and more than 3-fold in patients with PE (HR 3.4; 95% CI, 3.1-3.6). While the risk of cancer related death was nearly 3-fold in patient with DVT (HR 2.7; 95% CI, 2.4-3.1), and 5-fold in PE (HR 5.4; 95% CI, 4.9-6.0 respectively). The diagnosis of PE during the ED visit was associated with a significantly higher risk of cardiovascular death (HR 2.2; 95% CI, 1.9-2.6).

CONCLUSION

Patients with VTE have an elevated risk of all-cause mortality, including cardiovascular death.

Interventions to improve the appropriate use of polypharmacy for older people

BACKGROUND

Inappropriate polypharmacy is a particular concern in older people and is associated with negative health outcomes. Choosing the best interventions to improve appropriate polypharmacy is a priority, so that many medicines may be used to achieve better clinical outcomes for patients. This is the third update of this Cochrane Review.

OBJECTIVES

To assess the effects of interventions, alone or in combination, in improving the appropriate use of polypharmacy and reducing medication-related problems in older people.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL and two trials registers up until 13 January 2021, together with handsearching of reference lists to identify additional studies. We ran updated searches in February 2023 and have added potentially eligible studies to 'Characteristics of studies awaiting classification'.

SELECTION CRITERIA

For this update, we included randomised trials only. Eligible studies described interventions affecting prescribing aimed at improving appropriate polypharmacy (four or more medicines) in people aged 65 years and older, which used a validated tool to assess prescribing appropriateness. These tools can be classified as either implicit tools (judgement-based/based on expert professional judgement) or explicit tools (criterion-based, comprising lists of drugs to be avoided in older people).

DATA COLLECTION AND ANALYSIS

Four review authors independently reviewed abstracts of eligible studies, and two authors extracted data and assessed the risk of bias of the included studies. We pooled study-specific estimates, and used a random-effects model to yield summary estimates of effect and 95% confidence intervals (CIs). We assessed the overall certainty of evidence for each outcome using the GRADE approach.

MAIN RESULTS

We identified 38 studies, which includes an additional 10 in this update. The included studies consisted of 24 randomised trials and 14 cluster-randomised trials. Thirty-six studies examined complex, multi-faceted interventions of pharmaceutical care (i.e. the responsible provision of medicines to improve patients' outcomes), in a variety of settings. Interventions were delivered by healthcare professionals such as general physicians, pharmacists, nurses and geriatricians, and most were conducted in high-income countries. Assessments using the Cochrane risk of bias tool found that there was a high and/or unclear risk of bias across a number of domains. Based on the GRADE approach, the overall certainty of evidence for each pooled outcome ranged from low to very low. It is uncertain whether pharmaceutical care improves medication appropriateness (as measured by an implicit tool) (mean difference (MD) -5.66, 95% confidence interval (CI) -9.26 to -2.06; I2 = 97%; 8 studies, 947 participants; very low-certainty evidence). It is uncertain whether pharmaceutical care reduces the number of potentially inappropriate medications (PIMs) (standardised mean difference (SMD) -0.19, 95% CI -0.34 to -0.05; I2 = 67%; 9 studies, 2404 participants; very low-certainty evidence). It is uncertain whether pharmaceutical care reduces the proportion of patients with one or more PIM (risk ratio (RR) 0.81, 95% CI 0.68 to 0.98; I2 = 84%; 13 studies, 4534 participants; very low-certainty evidence). Pharmaceutical care may slightly reduce the number of potential prescribing omissions (PPOs) (SMD -0.48, 95% CI -1.05 to 0.09; I2 = 92%; 3 studies, 691 participants; low-certainty evidence), however it must be noted that this effect estimate is based on only three studies, which had serious limitations in terms of risk of bias. Likewise, it is uncertain whether pharmaceutical care reduces the proportion of patients with one or more PPO (RR 0.50, 95% CI 0.27 to 0.91; I2 = 95%; 7 studies, 2765 participants; very low-certainty evidence). Pharmaceutical care may make little or no difference to hospital admissions (data not pooled; 14 studies, 4797 participants; low-certainty evidence). Pharmaceutical care may make little or no difference to quality of life (data not pooled; 16 studies, 7458 participants; low-certainty evidence). Medication-related problems were reported in 10 studies (6740 participants) using different terms (e.g. adverse drug reactions, drug-drug interactions). No consistent intervention effect on medication-related problems was noted across studies. This also applied to studies examining adherence to medication (nine studies, 3848 participants).

AUTHORS' CONCLUSIONS

It is unclear whether interventions to improve appropriate polypharmacy resulted in clinically significant improvement. Since the last update of this review in 2018, there appears to have been an increase in the number of studies seeking to address potential prescribing omissions and more interventions being delivered by multidisciplinary teams.

Feasibility study of a clinical decision support system for polymedicated patients in primary care

Age-related changes in pharmacokinetics and pharmacodynamics, multimorbidity, frailty, and cognitive impairment represent challenges for drug treatments. Moreover, older adults are commonly exposed to polypharmacy, leading to increased risk of drug interactions and related adverse events, and higher costs for the healthcare systems. Thus, the complex task of prescribing medications to older polymedicated patients encourages the use of Clinical Decision Support Systems (CDSS). This paper evaluates the CDSS miniQ for identifying potentially inappropriate prescribing in poly-medicated older adults and assesses the usability and acceptability of the system in health care professionals, patients, and caregivers. The results of the study demonstrate that the miniQ system was useful for Primary Care physicians in significantly improving prescription, thereby reducing potentially inappropriate medication prescriptions for elderly patients. Additionally, the system was found to be beneficial for patients and their caregivers in understanding their medications, as well as usable and acceptable among healthcare professionals, patients, and caregivers, highlighting the potential to improve the prescription process and reduce errors, and enhancing the quality of care for elderly patients with polypharmacy, reducing adverse drug events, and improving medication management.

Association of anticholinergic drug use with postoperative mortality among patients with hip fracture. A nationwide cohort study

PURPOSE

Anticholinergic (AC) drugs are associated with various determinantal outcomes. Data regarding the effect of AC drugs on mortality among geriatric hip fracture patients are limited and inconsistent.

METHODS

Using Danish health registries, we identified 31,443 patients aged ≥65 years undergoing hip fracture surgery. AC burden was assessed 90 days before surgery by the Anticholinergic Cognitive Burden (ACB) score and number of AC drugs. Logistic and Cox regression producing odds ratios (OR) and hazard ratios (HR) for 30- and 365- day mortality, adjusting for age, sex, and comorbidities were computed.

RESULTS

AC drugs were redeemed by 42% of patients. The 30-day mortality increased from 7% for patients with ACB score of 0 to 16% for patients with ACB score of ≥5, corresponding to an adjusted OR 2.5 (CI: 2.0-3.1). The equivalent adjusted HR for 365-mortality was 1.9 (CI: 1.6-2.1). Using count of AC drugs as exposure we found a stepwise increase in ORs and HRs with increased number of AC drugs; Compared to non-users, adjusted ORs for 30-days mortality were 1.6 (CI: 1.4-1.7), 1.9 (CI: 1.7-2.1), and 2.3 (CI: 1.9-2.7) for users of 1, 2 and 3+ AC drugs. HRs for 365-day mortality were 1.4 (CI: 1.3-1.5), 1.6 (CI: 1.5-1.7) and 1.8 (CI: 1.7-2.0).

CONCLUSION

Use of AC drugs was associated with increased 30-day and 365-day mortality among older adults with hip fracture. Simply counting the number of AC drugs may be a clinically relevant and easy AC risk assessment tool. Continued effort to reduce AC drug-use is relevant.

Regional variations in excessive polypharmacy and potentially inappropriate drug use among older adults in Sweden: Trends from 2006 to 2020

Introduction: Potentially inappropriate drug use (PID) is common among older adults. Cross-sectional data suggest that there are marked regional variations in PID in Sweden. There is, however, a lack of knowledge about how the regional variations have changed over time. Objectives: This study aimed to investigate the regional differences in the prevalence of PID in Sweden, 2006-2020. Methods: In this repeated cross-sectional study, we included all older adults (≥75 years) registered in Sweden, yearly from 2006 to 2020. We used nationwide data from the Swedish Prescribed Drug Register linked at the individual level to the Swedish Total Population Register. We selected three indicators of PID according to the Swedish national "Quality indicators for good drug therapy in the elderly": 1) Excessive polypharmacy (use of ≥10 drugs); 2) Concurrent use of three or more psychotropic drugs; 3) Use of "drugs that should be avoided in older adults unless specific reasons exist." The prevalence of these indicators was calculated for each of Sweden's 21 regions, yearly from 2006 to 2020. The annual coefficient of variation (CV) was calculated for each indicator by dividing the standard deviation of the regions by the national average, to measure relative variability. Results: In the population of about 800,000 older adults per year, the national prevalence of "drugs that should be avoided in older adults," was reduced by 59% from 2006 to 2020. There was a slight decline in the use of three or more psychotropics, while the prevalence of excessive polypharmacy increased. The CV for excessive polypharmacy was 14% in 2006 and 9% in 2020 compared to 18% and 14% for "use of three or more psychotropics", and stable at around 10% for 'drugs that should be avoided in older adults.' Conclusions: The regional variation in potentially inappropriate drug use decreased or were stable from 2006 to 2020. The regional differences were largest for the use of three or more psychotropics. We found a general tendency that regions with a good performance at the start of the period performed well across the entire period. Future studies should investigate the reasons for regional variation and explore strategies to reduce unwarranted differences.

Issues with the Swedish e-prescribing system - An analysis of health information technology-related incident reports using an existing classification system

Objective

To identify issues with the Swedish e-prescribing system and devise a set of recommendations to overcome the identified challenges.

Methods

A number of health information technology-related incidents were collected retrospectively from various sources using purposive and snowball sampling. A search term containing five keywords was used to identify the electronic prescription-related incidents. The identified incidents (n = 24) were subjected to an existing framework, i.e., the Health Information Technology Classification System. Special attention was paid to the software-related issues, which were analysed using thematic analysis.

Results

Several types of software-related issues (n = 22) were identified: system configuration, interface with other software systems or components, software functionality, data storage and backup, record migration, software not accessible, and network/server down or slow. Both human and technical factors contributed to these incidents, including prescriptions not cancelled actively, drug handling errors, software programming errors, and system updates/upgrades. These software problems led to various consequences, such as incidents affecting multiple patients’ care management, delays in patient care, and risks of serious deterioration of health. Several temporary initiatives or administrative adjustments, for instance, cover letters to patients and local strategies, were used to overcome some of these challenges.

Conclusions

This study provides insights into the challenges related to the e-prescribing system, contributing factors, consequences, and actions taken to mitigate those risks. Therefore, healthcare organisations using the e-prescribing system should adopt the provided recommendations to minimise the risks of design and developmental challenges, implementation and use-related issues, and the problems related to monitoring, evaluation, and optimisation.

Performance of 3 Sets of Criteria for Potentially Inappropriate Prescribing in Older People to Identify Inadequate Drug Treatment

IMPORTANCE

Potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs) are used in research to reflect the quality of drug treatment in older people and have been suggested for inclusion in core outcome sets for evaluation of interventions for improved prescribing. Their validation so far, however, is primarily restricted to expert opinion-based processes.

OBJECTIVE

To evaluate the performance of 3 explicit PIM/PPO criteria sets as diagnostic tools to identify inadequate drug treatment in older patients.

DESIGN, SETTING, AND PARTICIPANTS

This diagnostic study analyzed patients aged 65 years or older consecutively included from 2 primary health care centers from October to November 2017. Data were analyzed from February to August 2022.

EXPOSURES

The PIMs/PPOs were concordantly identified by 2 specialist physicians (2018-2019) retrospectively after a planned physician visit, using 3 European PIM/PPO criteria sets and without knowledge of this diagnostic study.

MAIN OUTCOMES AND MEASURES

Area under the receiver operating characteristic (ROC) curve, reflecting the ability of PIM/PPO criteria sets to identify the reference standard of inadequate drug treatment, determined by 2 specialist physicians in consensus. Inadequate drug treatment implied that additional action related to the medication could be medically justified before the next regular visit.

RESULTS

A total of 302 patients were analyzed (median age, 74 [IQR, 69-81] years; 178 women [59%]; median number of drugs in the medication list, 6 [IQR, 3-9]); 98 patients (32%) had inadequate drug treatment. A total of 0 to 8 PIMs/PPOs per patient were identified using the Screening Tool of Older Persons' Prescriptions (STOPP)/Screening Tool to Alert to Right Treatment (START) criteria, 0 to 6 with the European EU(7)-PIM list, and 0 to 12 with the Swedish set of indicators of prescribing quality. The areas under the ROC curve for the 3 sets to identify the reference standard for inadequate drug treatment were 0.60 (95% CI, 0.53-0.66) for the STOPP/START criteria, 0.69 (95% CI, 0.63-0.75) for the EU(7)-PIM list, and 0.73 (95% CI, 0.67-0.80) for the Swedish set. For comparison, the area under the ROC curve was 0.71 (95% CI, 0.65-0.78) using the number of drugs in the medication list.

CONCLUSIONS AND RELEVANCE

In this diagnostic study, the evaluated PIM/PPO sets had poor to fair performance as diagnostic tools to identify inadequate drug treatment, comparable with a simple count of the number of drugs in the medication list. These findings suggest that use of PIMs/PPOs as indicators of drug treatment quality in core outcome sets for the evaluation of interventions for improved prescribing may need reconsideration.

Kidney function and prescribed dose in middle‐aged and older patients starting selective serotonin reuptake inhibitors

Purpose

To avoid adverse drug reactions, dose reductions are recommended when prescribing selective serotonin reuptake inhibitors (SSRIs) to patients with impaired kidney function. The extent of this practice in routine clinical care is however unknown. We aimed to evaluate the starting and maintenance SSRI doses prescribed to patients stratified by levels of kidney function in real‐world practice.

Methods

Using data from the Stockholm CREAtinine Measurements (SCREAM) project, we identified 101 409 new users of antidepressants (including 52 286 SSRI users) in the region of Stockholm during 2006–2019, who were ≥50 years of age and had a recent creatinine test taken in order to estimate glomerular filtration rate (eGFR). SSRI dose reduction was defined as a prescribed SSRI dose of ≤0.5 defined daily doses, according to current recommendations. We examined the associations between eGFR and reductions in initial dose and maintenance dose of SSRIs using logistic regression models.

Results

Overall, reductions in initial and maintenance dose were observed among 54.1% and 34.1% of new SSRI users. Nevertheless, about 40% of individuals with an eGFR <30 ml/min/1.73 m² were prescribed an SSRI without dose reduction. After adjusting for age and other covariates, lower eGFR was associated with moderately higher odds of dose reduction, for both initial and maintenance dose. Compared to individuals with an eGFR of 90–104 ml/min/1.73 m², the adjusted odds ratios for those with an eGFR <30 ml/min/1.73 m² were 1.18 (95% CI: 1.03, 1.36) for initial dose reduction, and 1.49 (1.29, 1.72) for maintenance dose reduction. Stratified analyses showed stronger associations between lower eGFR and SSRI dose reduction among individuals aged 50–64 years and in those receiving prescriptions from psychiatric care.

Conclusions

Lower kidney function was moderately associated with a reduced SSRI dose, independently of age. Prescribing SSRIs to middle‐aged and older patients should not only consider patients' age but also their kidney function.

Clinical relevance of potentially inappropriate medications and potential prescribing omissions according to explicit criteria-a validation study

PURPOSE

To investigate the clinical relevance of potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs), and to evaluate the association between PIMs/PPOs and inadequate drug treatment.

METHODS

PIMs/PPOs, concordantly identified by two physicians applying the STOPP/START criteria, the EU(7)-PIM list, and a Swedish set in 302 consecutive older primary care patients, were assessed regarding clinical relevance for the specific patient. The physicians determined, in consensus, whether an action related to the medication was medically justified prior to the next regular consultation. If so, the drug treatment was categorised as inadequate, and if not, the treatment was considered adequate.

RESULTS

In all, 259 (86%) patients had 1010 PIMs/PPOs, 150 (15%) of which, in 81 (27%) patients, were assessed as clinically relevant (kappa: 0.26). A total of 75 (50%) clinically relevant PIMs and PPOs were prioritised for medical action before the next regular consultation. Action-requiring clinically relevant PIMs most often concerned acetylsalicylic acid (ASA) for primary prevention (four out of 68 patients on ASA). The corresponding PPOs concerned beta-blockers in ischaemic heart disease (four out of 61 patients with this condition). When an overall medical perspective was applied, 164 (63%) out of 259 patients with PIMs/PPOs were assessed as having adequate treatment. In adjusted logistic regression, number of PIMs and/or PPOs and number of drugs were associated with inadequate drug treatment.

CONCLUSION

One in seven PIMs/PPOs may be clinically relevant, half of these not of priority for medical action. Cautious interpretation is warranted when PIMs/PPOs are used as outcome measures.

Health system reforms and the needs of the ageing population—an analysis of recent policy paths and reform trends in Finland and Sweden

Population ageing with an increasing number of people experiencing complex health and social care needs challenges health systems. We explore whether and how health system reforms and policy measures adopted during the past two decades in Finland and Sweden reflect and address the needs of the older people. We discuss health system characteristics that are important to meet the care needs of older people and analyse how health policy agendas have highlighted these aspects in Finland and Sweden. The analysis is based on “most similar cases”. The two countries have rather similar health systems and are facing similar challenges. However, the policy paths to address these challenges are different. The Swedish health system is better resourced, and the affordability of care better ensured, but choice and market-oriented competition reforms do not address the needs of the people with complex health and social care needs, rather it has led to increased fragmentation. In Finland, the level of public funding is lower which may have negative impacts on people who need multiple services. However, in terms of integration and care coordination, Finland seems to follow a path which may pave the way for improved coordination of care for people with multiple care needs. Intensified monitoring and analysis of patterns of health care utilization among older people are warranted in both countries to ensure that care is provided equitably.

Drug interaction alerts in older primary care patients, and related medically justified actions

PURPOSE

To describe presented interaction alerts in older patients, and the extent to which these require further medical action for the specific patient or are already being addressed.

METHODS

Interaction alerts presented at a physician consultation, for 274 consecutive primary care patients treated with two or more drugs (median age: 75 years; 59% female), were extracted. These alerts are based on Janusmed, a decision support integrated in the medical records that provides recommendations for managing the interactions. One general practitioner (GP) and one GP/clinical pharmacologist determined in retrospect, first independently and then in consensus, whether the alerts justified further medical action, considering each patient's health condition.

RESULTS

In all, 405 drug interaction alerts in 151 (55%) patients were triggered. Medical action in response was deemed medically justified for 35 (9%) alerts in 26 (17%) patients. These actions most often involved a switch to a less interacting drug from the same drug class (n = 10), a separate intake (n = 9), or the ordering of a laboratory test (n = 8). Out of 531 actions suggested by the alert system, only 38 (7%) were applicable to the specific patient, as, for instance, laboratory parameters were already being satisfactorily monitored or a separate intake implemented.

CONCLUSIONS

More than every other older patient receives drug treatment that triggers drug interaction alerts. Nine in ten alerts were already being addressed or were not relevant in the clinical setting, whereas, for the remaining tenth, some medical action, that for unknown reasons had not been taken, was reasonable. These findings show that interaction alerts are questionable as indicators of problematic prescribing.

Implementation of E-prescription for Multidose Dispensed Drugs: Qualitative Study of General Practitioners' Experiences

Background

Increased use of pharmaceuticals challenges both capacity and safety related to medication management for patients and changes in how general practitioners (GPs) and other health personnel interact with and follow up with patients. E-prescribing of multidose drug dispensing (eMDD) is 1 of the national measures being tested in Norway.

Objective

The objective of this study is to explore GPs’ experiences with the challenges and benefits of implementing eMDD in Norway.

Methods

Qualitative in-depth and group interviews were conducted with a total of 25 GPs between 2018 and 2020. Transcribed files were saved in NVivo to conduct a step-by-step content analysis. NVivo is a software tool for organizing, managing, and analyzing qualitative data.

Results

The study revealed that eMDD offers many benefits. At the same time, there are several challenges related to information, training, and initiation, as well as to the responsibility for the medication, interactions, and the risk of incorrect medication. An important activity in the start-up phase was an information meeting with pharmacies and technology suppliers, as well as exchanging information and instructions with pharmacies on how to get started. Four analytic themes emerged through the extraction of data: (1) start-up with eMDD (“Be patient”); (2) the need for training; (3) interaction, safety, and efficiency; and (4) the working day with eMDD.

Conclusions

There is a variation in different GPs’ needs regarding training and information, and considerable variation in competence and motivation related to the use of digital tools. There are also different degrees of understanding the everyday work of the other actors in the medication chain. In particular, the harmonization of medication lists related to the use of time, expenditures, and challenges with technological solutions in the introduction phase was emphasized as a challenge. Overall, GPs who have started using the system report great benefits; these are largely related to an increased overview of patients’ total medication lists, less time spent on prescribing prescriptions, and increased collaboration with pharmacies and nurses, both in service from providers in homes and in nursing homes.

Association between recorded medication reviews in primary care and adequate drug treatment management - a cross-sectional study

OBJECTIVE

To investigate the association between a recorded procedure code for a medication review and adequate drug treatment management, and to explore factors associated with this code.

DESIGN AND SETTING

Cross-sectional study; two primary health care centres, in Region Västra Götaland, Sweden.

SUBJECTS

A total of 302 consecutive patients (≥65 years old, 59% female; median number of drugs: six) requiring a non-urgent consultation with a physician in October-November 2017.

MAIN OUTCOME MEASURE

Adequate drug treatment management (treatment that did not require any further action), determined in consensus by two specialists in family medicine blinded to the medication review code.

RESULTS

Adequate drug treatment management was, overall, less common in those with a recorded medication review over the last year: 63% versus 73% (p = 0.047). This negative association was evident among patients aged 65-74 years: 49% versus 74% (p = 0.003), but absent in those ≥75 years old: 67% versus 70% (p = 0.77). Recommendations from consensus included the search for additional information to be able to make a decision regarding initiation or withdrawal of a drug (n = 53), withdrawal of a drug (n = 41), or ordering a laboratory test (n = 25). Factors associated with a recorded procedure code included age above the remuneration limit of 75 years (odds ratio: 9.8; 95% confidence interval 5.0-19), type 2 diabetes (3.0 (1.5-6.2)), hypertension (2.4 (1.2-4.8)), and depression (2.5 (1.02-6.0)).

CONCLUSIONS

The presence of a recorded medication review was not positively associated with adequate drug treatment management but was associated with the age limit for remuneration, and some chronic diseases.Key pointsTo improve drug treatment in older people in primary care, a remuneration system linked to recorded medication reviews has been introduced.In this study, fewer patients with than without a recorded medication review (63% versus 73%) had adequate drug treatment management.A recorded medication review was ten times more common in those ≥75 years, that is, the age limit for remuneration.Recorded codes for medication reviews were also common in those with type 2 diabetes, hypertension, and depression.

Investigating Potential Drug-Drug Interactions from Greek e-Prescription Data

BACKGROUND

The prevalence of potential drug-drug interactions (pDDIs) is indicative of the prevalence of actual drug-drug interactions and prescription quality. However, they are significantly understudied in Greece.

OBJECTIVE

To determine the prevalence of pDDIs among outpatients and identify factors associated with their occurrence.

METHODS

Anonymous e-prescription data between 2012 and 2017 were obtained from community pharmacies in Thessaloniki, Greece. Patients taking more than one medication for at least three months were included. pDDIs were identified and categorized depending on their clinical significance using Drug Interactions Checker. Crude and adjusted odds ratios (ORs) with accompanying 95% confidence intervals (CIs) of risk factors of pDDIs occurrence were identified using multivariable logistic regression.

RESULTS

During the study period, 6,000 anonymous e-prescriptions (1,000 per year) satisfying the inclusion criteria, were collected. The overall prevalence of major pDDIs was 17.4% (63.0% for moderate pDDIs). The most common major pDDIs were between amlodipine and simvastatin (22.8% of major interactions) followed by clopidogrel and omeprazole (6.4% of major interactions). Polypharmacy (≥5 concomitantly received medications) was associated with an increased risk of major pDDIs (adjusted OR, 5.72; 95% CI, 4.87-6.72); no associations were observed regarding age, sex and number of prescribing physicians.

CONCLUSION

The prevalence of pDDIs in this study was higher than previously reported in other European countries, with polypharmacy being a potential risk factor. Those results argue for a need for improvement in the area of prescribing in Greece.

Deprescribing in the Older Patient: A Narrative Review of Challenges and Solutions

Polypharmacy is a major challenge in healthcare for older people, and is associated with increased risks of adverse outcomes, such as delirium, falls, frailty, cognitive impairment and hospitalization. There is significant public and professional interest in the role of deprescribing in reducing medication-related harms in older people. We aim to provide a narrative review of 1) the safety and efficacy of deprescribing interventions, 2) the challenges and solutions of deprescribing research and implementation in clinical practice, and 3) the benefits of using Computerized Clinical Decision Support Systems (CCDSS) and Quality Indicators (QIs) in deprescribing research and practice. Deprescribing is an established management strategy to minimize polypharmacy and potentially inappropriate medications. There is limited clinical evidence for its efficacy on global and geriatric outcomes. Various challenges at patient, healthcare professional and healthcare system levels may impact on the success of deprescribing interventions in research and practice. Management strategies that target all levels of the healthcare system are required to overcome these challenges. Future studies may consider large multicenter prospective designs to establish the effects and sustainability of deprescribing interventions on clinical outcomes.

Trends and concerns of potentially inappropriate medication use in patients with cardiovascular diseases

Introduction: The use of potentially inappropriate medications (PIM) is an alarming social risk factor in cardiovascular patients. PIM administration may result in iatrogenic disorders and adverse consequences may be attenuated by limiting PIM intake.Areas covered: The goal of this review article is to discuss the trends, risks, and concerns regarding PIM administration with focus on cardiovascular patients. To find data, we searched literature using electronic databases (Pubmed/Medline 1966-2021 and Web of Science 1975-2021). The data search terms were cardiovascular diseases, potentially inappropriate medication, potentially harmful drug-drug combination, potentially harmful drug-disease combination, drug interaction, deprescribing, and electronic health record.Expert opinion: Drugs for heart diseases are the most commonly prescribed medications in older individuals. Despite the availability of explicit and implicit PIM criteria, the incidence of PIM use in cardiovascular patients remains high ranging from 7 to 85% in different patient categories. Physician-induced disorders often occur when PIM is administered and adverse effects may be reduced by limiting PIM intake. Main strategies promising for addressing PIM use include deprescribing, implementation of systematic electronic records, pharmacist medication review, and collaboration among cardiologists, internists, geriatricians, clinical pharmacologists, pharmacists, and other healthcare professionals as basis of multidisciplinary assessment teams.

Effects of Hospital-Based Comprehensive Medication Reviews Including Postdischarge Follow-up on Older Patients' Use of Health Care: A Cluster Randomized Clinical Trial

Importance

Suboptimal use of medications is a leading cause of health care-related harm. Medication reviews improve medication use, but evidence of the possible benefit of inpatient medication review for hard clinical outcomes after discharge is scarce.

Objective

To study the effects of hospital-based comprehensive medication reviews (CMRs), including postdischarge follow-up of older patients' use of health care resources, compared with only hospital-based reviews and usual care.

Design, Setting, and Participants

The Medication Reviews Bridging Healthcare trial is a cluster randomized crossover trial that was conducted in 8 wards with multiprofessional teams at 4 hospitals in Sweden from February 6, 2017, to October 19, 2018, with 12 months of follow-up completed December 6, 2019. The study was prespecified in the trial protocol. Outcome assessors were blinded to treatment allocation. In total, 2644 patients aged 65 years or older who had been admitted to 1 of the study wards for at least 1 day were included. Data from the modified intention-to-treat population were analyzed from December 10, 2019, to September 9, 2020.

Interventions

Each ward participated in the trial for 6 consecutive 8-week periods. The wards were randomized to provide 1 of 3 treatments during each period: CMR, CMR plus postdischarge follow-up, and usual care without a clinical pharmacist.

Main Outcomes and Measures

The primary outcome measure was the incidence of unplanned hospital visits (admissions plus emergency department visits) within 12 months. Secondary outcomes included medication-related admissions, visits with primary care clinicians, time to first unplanned hospital visit, mortality, and costs of hospital-based care.

Results

Of the 2644 participants, 7 withdrew after inclusion, leaving 2637 for analysis (1357 female [51.5%]; median age, 81 [interquartile range, 74-87] years; median number of medications, 9 [interquartile range, 5-13]). In the modified intention-to-treat analysis, 922 patients received CMR, 823 received CMR plus postdischarge follow-up, and 892 received usual care. The crude incidence rate of unplanned hospital visits was 1.77 per patient-year in the total study population. The primary outcome did not differ between the intervention groups and usual care (adjusted rate ratio, 1.04 [95% CI, 0.89-1.22] for CMR and 1.15 [95% CI, 0.98-1.34] for CMR plus postdischarge follow-up). However, CMR plus postdischarge follow-up was associated with an increased incidence of emergency department visits within 12 months (adjusted rate ratio, 1.29; 95% CI, 1.05-1.59) compared with usual care. There were no differences between treatment groups regarding other secondary outcomes.

Conclusions and Relevance

In this study of older hospitalized patients, CMR plus postdischarge follow-up did not decrease the incidence of unplanned hospital visits. The findings do not support the performance of hospital-based CMRs as conducted in this trial. Alternative forms of medication reviews that aim to improve older patients' health outcomes should be considered and subjected to randomized clinical trials.

Inter-rater reliability of assessments regarding the quality of drug treatment, and drug-related hospital admissions

AIMS

To investigate inter-rater agreement on the quality of drug treatment, and the relationship between the drug treatment and hospital admission.

METHODS

Three specialist physicians and two resident physicians determined, independently and in consensus, the quality of drug treatment from an overall medical perspective, and its association with admission, in 30 randomly selected patients (50% female, median age 72 years) admitted to Sahlgrenska University Hospital, Sweden, in April 2018. The inter-rater agreement was evaluated with Gwet's agreement coefficient (AC₁ ).

RESULTS

In all, 200 (95%) out of 210 drugs at admission and 238 (97%) out of 245 drugs at discharge were assessed as reasonable drug treatment by all assessors. Conversely, none of the drugs at admission, and two at discharge, were assessed as unreasonable drug treatment by all assessors (AC₁ : 0.88 and 0.94 [all], 0.86 and 0.95 [specialists], 0.92 and 0.92 [residents], respectively). The assessments regarding the association between the drug treatment and the hospital admission (not related or main/contributory reason) were consistent between the assessors for 16 out of 30 patients (AC₁ : 0.67 [all], 0.74 [specialists], 0.54 [residents]). In none of the three cases where the hospital admission was considered possibly attributable to a prescribing error did the assessors make consistent assessments.

CONCLUSIONS

As the inter-rater agreement ranged between weak and almost perfect, the reliability of assessments of drug treatment quality, as well as adverse consequences, appears to be a methodological concern. To yield acceptably reliable results regarding both drug treatment aspects at issue, specialist physicians should be involved.

Regional variation in potentially inappropriate medicine use in older adults. - A national register-based cross-sectional study on economic, health system-related and patient-related characteristics

BACKGROUND

Potentially inappropriate medicines (PIM), i.e. medicines in which the potential harms may outweigh the benefits, use may be associated with e.g. hospitalization, outpatient visits and health care costs. As regional institutions are often responsible for financing pharmaceuticals, understanding the regional variation of PIM use could help to tackle the associated problems and costs.

OBJECTIVE

To explore regional variation in PIM use among older adults and the association with regional health-system related, patient-related and economic characteristics and the frequency of PIM use.

METHODS

This is a nation-wide study based on the Finnish Prescription Register. PIM use was defined according to the Finnish Meds75+ database and regional characteristics derived from national statistics.

RESULTS

Variation at the hospital district level was large, with the largest difference between the most and least PIM prescribing being 45.2%. The factors associated with high PIM prescribing were a higher share of women and a higher number of private doctor visits per inhabitant in a municipality. The factor associated to lower PIM prescribing was a higher share of Swedish-speaking population. The studied factors explained 23% of the municipal-level variation in PIM.

CONCLUSIONS

Large regional differences may lead to regional inequality in prescribing and in the distribution of pharmaceutical costs. As only a small share of the variation was explained by economic, health system-related and patient-related factors, the key reasons may lie in unobserved prescribing practices.

District nurses' use of a decision support and assessment tool to improve the quality and safety of medication use in older adults: a feasibility study

Aim:

To investigate whether district nurses (DNs) can identify factors related to the quality and safety of medication use among older patients via a clinical decision support system (CDSS) for medication and an instrument for assessing the safety of drug use [the Safe Medication Assessment tool (SMA)]. A secondary aim was to describe patients’ experiences of the assessment.

Background:

DNs in Stockholm County have the opportunity to establish special units at primary health care centers (PHCCs) for patients aged 75 years and older. The units conduct drug utilization reviews and create care plans for older adults.

Methods:

Nine DNs at 7 PHCCs in Stockholm County used the tools with 45 patients aged 75 years and older who used one or more drugs. Outcome measures were the number of drugs, potential drug-related problems, nursing interventions, and patient satisfaction. Prevalences of drug-related problems and nursing interventions were calculated. Eleven patients answered a telephone questionnaire on their experiences of the assessment.

Findings:

DNs identified factors indicative of drug-related problems, including polypharmacy (9.8 drugs per person), potential drug–drug interactions (prevalence 40%), potential adverse drug reactions (2.7 per person), and prescribers from more than two medical units (60%). DNs used several nursing interventions to improve the safety of medication use (e.g., patient education, initiating a pharmaceutical review). The patients thought it was meaningful to receive information about their drug use and important to identify potential drug-related problems. With the support of the CDSS and the SMA tool, the DNs could identify several factors related to inappropriate or unsafe medication and initiated a number of interventions to improve medication use. The patients were positive toward the assessments. Using these tools, the DNs may help promote safe medication use in older patients.

Associations of Polypharmacy and Inappropriate Medications with Adverse Outcomes in Older Adults with Cancer: A Systematic Review and Meta-Analysis

BACKGROUND

Polypharmacy (PP) and potentially inappropriate medications (PIM) are highly prevalent in older adults with cancer. This study systematically reviews the associations of PP and/or PIM with outcomes and, through a meta-analysis, obtains estimates of postoperative outcomes associated with PP in this population.

MATERIALS AND METHODS

We searched PubMed, Embase, Web of Science, and Cochrane Register of Clinical Trials using standardized terms for concepts of PP, PIM, and cancer. Eligible studies included cohort studies, cross-sectional studies, meta-analyses, and clinical trials which examined outcomes associated with PP and/or PIM and included older adults with cancer. A random effects model included studies in which definitions of PP were consistent to examine the association of PP with postoperative complications.

RESULTS

Forty-seven articles met the inclusion criteria. PP was defined as five or more medications in 57% of the studies. Commonly examined outcomes included chemotherapy toxicities, postoperative complications, functional decline, hospitalization, and overall survival. PP was associated with chemotherapy toxicities (4/9 studies), falls (3/3 studies), functional decline (3/3 studies), and overall survival (2/11 studies). A meta-analysis of four studies indicated an association between PP (≥5 medications) and postoperative complications (overall odds ratio, 1.3; 95% confidence interval [1.3-2.8]). PIM was associated with adverse outcomes in 3 of 11 studies.

CONCLUSION

PP is associated with postoperative complications, chemotherapy toxicities, and physical and functional decline. Only three studies showed an association between PIM and outcomes. However, because of inconsistent definitions, heterogeneous populations, and variable study designs, these associations should be further investigated in prospective studies.

IMPLICATIONS FOR PRACTICE

Polypharmacy and potentially inappropriate medications (PIM) are prevalent in older adults with cancer. This systematic review summarizes the associations of polypharmacy and PIM with health outcomes in older patients with cancer. Polypharmacy and PIM have been associated with postoperative complications, frailty, falls, medication nonadherence, chemotherapy toxicity, and mortality. These findings emphasize the prognostic importance of careful medication review and identification of PIM by oncology teams. They also underscore the need to develop and test interventions to address polypharmacy and PIM in older patients with cancer, with the goal of improving outcomes in these patients.

Medicamentos potencialmente inapropriados prescritos a pacientes de um Centro de Referência em Atenção à Saúde da Pessoa Idosa

Resumo Objetivo Analisar o perfil farmacoterapêutico dos idosos atendidos em um Centro de Referência em Atenção à Saúde da Pessoa Idosa quanto ao uso de medicamentos potencialmente inapropriados (MPI) por meio de três critérios de rastreamento e determinar fatores associados à prescrição de MPI. Método Estudo transversal com dados obtidos por revisão retrospectiva dos prontuários de idosos, atendidos entre 2017 e 2018 por médico geriatra. Para identificar os MPI, utilizaram-se os Critérios de Beers, o Screening Tool of Older Persons’ Potentially Inappropriate Prescriptions (STOPP) e o Consenso Brasileiro de Medicamentos Potencialmente Inapropriados para Idosos. Características relacionadas ao perfil sociodemográfico (idade e sexo), de hábitos de vida (tabagismo e consumo de álcool), clínico (doenças) e farmacoterapêutico (medicamentos e Índice de Complexidade da Farmacoterapia - ICFT) foram avaliadas. Resultados Foram analisados 406 prontuários e identificados 3.059 medicamentos prescritos, dos quais 32,1% são MPI segundo Critérios STOPP, 14,4% pelo Consenso Brasileiro e 11,7% pelos Critérios de Beers. No total, 81,1% dos idosos apresentaram ao menos um MPI. Regressão de Poisson demonstrou associação entre a prescrição de MPI com polifarmácia, maior número de sinais e sintomas e maior valor de ICFT em ao menos um dos critérios. A força de concordância entre os critérios de MPI foi moderada. Conclusões A maioria dos prontuários analisados possuíam ao menos um MPI prescrito, sendo que os Critérios STOPP identificaram uma maior quantidade de MPI. Estratégias devem ser implementadas para melhorar a farmacoterapia dos idosos com atenção para os que apresentam fatores associados a MPI em seu perfil.

Updating and validating quality prescribing indicators for use in Australian general practice

This study aims to update and validate quality prescribing indicators (QPIs) for Australian general practice. The study comprised two phases: (1) developing preliminary potential QPIs based on the 2006 National Prescribing Service (NPS) MedicineWise indicators, published literature, international indicators and guidelines, and through qualitative focus group discussions; and (2) validating the proposed QPIs through a two-round online survey using the Delphi technique. The Delphi panel included four GPs, four pharmacists and two clinical pharmacologists. The Delphi panel rated the potential QPIs for their validity, importance and feasibility using a 1-10 Likert scale. In round one, all proposed QPIs presented as 'prescribing rules' achieved high scores regarding validity, importance and feasibility No rule was eliminated and three new rules were introduced. Rules were reworded into 'prescribing indicators' for round two, which resulted in 35 indicators being accepted and two indicators being eliminated. The final QPIs also include seven drug-drug interactions, which received high scores in round one. In conclusion, 42 QPIs were nominated for use in Australian general practice, based on their validity, importance and feasibility. If implemented, these QPIs have the potential to assist in efforts to improve the quality and safety of medicines management.

Use of non-benzodiazepine hypnotics is associated with falls in nursing home residents: a longitudinal cohort study

BACKGROUND

Falls and related injuries are common among older people, and several drug classes are considered to increase fall risk.

AIMS

This study aimed to investigate the association between the use of certain drug classes and falls in older nursing home residents in Sweden, and relate these to different age groups.

METHODS

Information on falls that occurred in the previous year and regular use of possible fall risk drugs including non-benzodiazepine hypnotics (zopiclone and zolpidem) was collected from 331 nursing home residents during 2008-2011. Over the following 6 months, the occurrence of serious falls, requiring a physician visit or hospital care, was registered. Association between serious falls and drug use was compared between an older (≥ 85 years) and a younger group.

RESULTS

An increased fall risk (Downton Fall Risk Index ≥ 3) was found in 93% of the study subjects (aged 65-101 years). Baseline data indicated an association between falls that occurred in the previous year and regular use of non-benzodiazepine hypnotics (p = 0.005), but not with the other studied drug classes. During the following 6 months, an association between use of non-benzodiazepine hypnotics and serious falls in the older group (p = 0.017, odds ratio 4.311) was found. No association was found between the other studied drug classes and serious falls.

DISCUSSION

These results indicate an association between falls and the use of non-benzodiazepine hypnotics, compounds that previously have been considered generally well-tolerated in older people.

CONCLUSIONS

Caution is advocated when using non-benzodiazepine hypnotics regularly in older people living in nursing homes.

A collaborative intervention for deprescribing: The role of stakeholder and patient engagement

BACKGROUND

At a recent World Café Workshop on future deprescribing priorities, Canadian researchers identified that, in addition to implementation evaluation and economic analyses, high quality clinical trials require meaningful patient engagement.

OBJECTIVES

The aim was to develop a deprescribing intervention for collaborative primary healthcare clinics and long-term care facilities that have pharmacists integrated in these settings. This manuscript aims to provide a summary of the experience with engaging patients in the development of the deprescribing framework.

METHODS

Sixteen members of the research team met with six patient representatives (identified by the Maritime SPOR SUPPORT Unit) in a facilitated meeting. The event provided a welcoming environment for all participants; discussion groups ensured a mix of clinical, research and patient voice; and facilitators focused on engaging all voices equally. Initial discussions were structured around four topics: 1) identifying and prioritizing potentially inappropriate medications to reduce or stop; 2) identifying patients appropriate for deprescribing; 3) effectively communicating deprescribing with both patients and prescribers; and 4) measuring satisfaction with the framework. Subsequent discussions used group input to draft an intervention. After the event, participants engaged via e-mail, to refine the proposed intervention.

RESULTS

The facilitated meeting provided helpful insight into patients' interests and changed the shape of the project. For example, patient representatives felt that an age restriction of 65 years of age or older was unfair, as deprescribing may help people younger than 65 years of age. Patient representatives also felt it was crucial to have resources to offer with non-pharmacologic information to increase success of deprescribing. This led to the deprescribing intervention becoming a framework for pharmacist-led deprescribing and a toolbox of supportive patient and healthcare professional resources.

CONCLUSIONS

Overall, this process allowed for successful and meaningful patient engagement that aligned well with priorities for deprescribing clinical trials.

Quality of prescribing in older people from a broad family physician perspective: a descriptive pilot study

OBJECTIVES

To investigate the quality of drug treatment in older people from a broad family physician perspective, and to provide evidence for power calculations in full-scale studies on prescribing quality.

DESIGN

Descriptive, retrospective pilot study.

SETTING

A primary healthcare centre in Sweden.

PARTICIPANTS

123 consecutive patients, ≥65 years, with a non-urgent physician consultation in January 2016.

MEASURES

The drug treatment was assessed by a physician as either appropriate or suboptimal, taking individual factors like morbidity, life expectancy and concurrent drug treatment into account, and preceded by the application of 493 criteria from three screening tools for Potentially Inappropriate Medications (PIMs) and Potential Prescribing Omissions (PPOs). Suboptimal drug treatment was further categorised regarding priority: (1) immediate change suggested or (2) actions suggested in the longer term. Prevalence of the procedure code 'medication review' and the results thereof were also recorded.

RESULTS

Median age: 76 years; 48% women. When a family physician perspective was applied, and 593 PIMs/PPOs identified in 117 (95%) patients considered, 45 (37%) patients had suboptimal drug treatment. Immediate handling was suggested in 13 (11%) patients, most often concerning withdrawals of drugs for anxiety and insomnia. Handling in the longer term was suggested in 32 (26%) patients, most often concerning overuse of proton pump inhibitors. Over the last year, the procedure code 'medication review' was recorded for 65 (53%) patients. In medication reviews recorded during January 2016 (n=45), 23 (7%) drugs out of 309 were acted on, most often a dosage adjustment.

CONCLUSIONS

This pilot study shows that when a broad family physician perspective is applied, taking individual factors and medical priorities in the complex clinical situation into account, drug treatment in primary care is appropriate for the majority of older patients. The results may be useful in sample size considerations for future studies on prescribing practices.

Reducing Potentially Inappropriate Medications in Older Adults: A Way Forward

La réduction des médicaments potentiellement inappropriés (MPI) chez les personnes âgées est un enjeu important selon de nombreux cliniciens et chercheurs à travers le monde, car ces médicaments accroissent significativement la morbidité et la mortalité dans la population plus âgée. La prévalence des MPI est un problème répandu malgré l’existence de plusieurs critères explicites et implicites de réduction des MPI chez les personnes âgées, les plus courants étant les critères de Beers, les critères STOPP/START et plusieurs critères nationaux spécifiques. Cette revue non systématique visait à examiner les critères de référence pour la réduction des MPI et à clarifier le rôle de certaines mesures, dont la déprescription, pour optimiser la prescription des médicaments chez les personnes âgées. Des recherches par mots-clés et termes MeSH ont été menées dans des bases de données électroniques. Les nombreux critères disponibles ont chacun leurs avantages et inconvénients. La déprescription, qui vise à réduire l’utilisation des MPI, a considérablement gagné en importance dans les initiatives associées à l’amélioration des pratiques de prescription. La déprescription est une approche méthodique qui implique l’arrêt graduel, éclairé et individualisé des médicaments inappropriés, avec un suivi rigoureux des patients pour assurer la détection d’événements indésirables ou de symptômes de rebond. Une approche combinée centrée sur le patient et le soignant favorise la collaboration entre les prescripteurs et les pharmaciens afin de réduire le nombre de MPI chez les personnes âgées.

Developing professional confidence in the art of prescribing-a randomized controlled study on structured collegial discussions during internship

PURPOSE

To evaluate whether an educational intervention based on collegial discussions on patient cases could increase interns' professional confidence in prescribing.

METHODS

In a randomized controlled study at Sahlgrenska University Hospital, Gothenburg, Sweden, 69 interns (median age: 29 years, 54% female) were allocated to an intervention or control group. The intervention consisted of two 3-h seminars based on collegial discussions of patient cases focused on performing medication reviews. This included reconciling the drug treatment and ascertaining that it is reasonable given the patient's current health status, as well as tips on practical handling of the medical records system and integrated decision support. Self-assessed confidence in performing medication reviews was evaluated with questionnaires distributed at baseline and at 6-month follow-up.

RESULTS

Fifty-seven (83%) interns completed the questionnaires. Although the opposite was found at baseline, intervention interns, in comparison with controls, at follow-up, were more confident in performing medication reviews (4.3 ± 0.9 vs. 3.6 ± 1.3, P = 0.034; 1 = completely disagree to 5 = completely agree). At follow-up, the intervention participants had increased their confidence in prescribing to a greater extent compared with the control participants, including performing medication reviews as well as taking responsibility for the medication list at discharge: + 1.5/+ 1 vs ± 0 on the 5-point agreement scale (all P ≤ 0.01). Among other positive outcomes, the intervention increased the interns' awareness of adverse effects as a potential cause of symptoms and their confidence in withdrawing a medication.

CONCLUSION

Structured collegial discussions on pharmacotherapy, even of a relatively short duration, can increase junior physicians' professional confidence in prescribing medicines.

Registered nurses' use of computerised decision support in medication reviews

Purpose The purpose of this paper is to explore the implications of registered nurses' (RNs) use of a computerized decision support system (CDSS) in medication reviews. Design/methodology/approach The paper employs a quasi-experimental, one-group pre-test/post-test design with three- and six-month follow-ups subsequent to the introduction of a CDSS. In total, 11 RNs initiated and prepared a total of 54 medication reviews. The outcome measures were the number of drug-related problems (DRPs) as reported by the CDSS and the RNs, respectively, the RNs' views on the CDSS, and changes in the quality of drug treatment. Findings The CDSS significantly indicated more DRPs than the RNs did, such as potential adverse drug reactions (ADRs). The RNs detected additional problems, outside the scope of the CDSS, such as lack of adherence. They considered the CDSS beneficial and wanted to continue using it. Only minor changes were found in the quality of drug treatments, with no significant changes in the drug-specific quality indicators (e.g. inappropriate drugs). However, the use of renally excreted drugs in reduced renal function decreased. Practical implications The RNs' use of a CDSS in medication reviews is of value in detecting potential ADRs and interactions. Yet, in order to have an impact on outcomes in the quality of drug treatment, further measures are needed. These may involve development of inter-professional collaboration, such as established procedures for the implementation of medication reviews, including the use of CDSS. Originality/value This is, to the best of the authors' knowledge, the first study to explore the implications of medication reviews, initiated and prepared by RNs who use a CDSS. The paper adds further insight into the RNs' role in relation to quality of drug treatments.

Developing confidence in basic prescribing skills during medical school: a longitudinal questionnaire study investigating the effects of a modified clinical pharmacology course

PURPOSE

To investigate if increased focus on pharmacotherapy during medical school can increase students' confidence in basic prescribing skills, that is, performing medication reviews and writing medication discharge summaries.

METHODS

In 2016, the clinical pharmacology course in medical school in Gothenburg, Sweden, was modified to facilitate the students' acquisition of prescribing skills, with (i) clarified learning outcomes; (ii) supply of a list of common drugs for self-completion; (iii) instructions to practice medication reviews/discharge summaries during the ward-based education; and (iv) a concluding compulsory seminar where the students were to present prescribing-related experiences from their ward-based attendance. Questionnaires were administered to students participating in the course before (2016; n = 101) and after (2017; n = 137) implementation of the modifications. Students were asked to grade their agreement from 1 (totally disagree) to 5 (totally agree) on statements related to their perceived confidence in basic prescribing skills.

RESULTS

In all, 195 students returned the questionnaire (response rate 82%; median age 24 years; 68% female). Confidence was rated higher after the modifications were implemented, both regarding medication reviews and medication discharge summaries, after vs. before 3.6 ± 1.2 vs. 3.2 ± 1.0 (P = 0.024), and 4.3 ± 0.9 vs. 3.9 ± 1.1 (P = 0.008), respectively. The adjusted odds for being confident in performing these tasks were 1.49/1.36 times greater after the course modifications (P = 0.047/0.019). Perceived confidence in performing medication reviews/summary reports was positively correlated with numbers performed (P < 0.0001).

CONCLUSIONS

Modifications of the clinical pharmacology course during medical school, focusing on students' training in pharmacotherapy, was associated with increased confidence of this core skill for a physician.

Interventions to improve the appropriate use of polypharmacy for older people

BACKGROUND

Inappropriate polypharmacy is a particular concern in older people and is associated with negative health outcomes. Choosing the best interventions to improve appropriate polypharmacy is a priority, hence interest in appropriate polypharmacy, where many medicines may be used to achieve better clinical outcomes for patients, is growing. This is the second update of this Cochrane Review.

OBJECTIVES

To determine which interventions, alone or in combination, are effective in improving the appropriate use of polypharmacy and reducing medication-related problems in older people.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL and two trials registers up until 7 February 2018, together with handsearching of reference lists to identify additional studies.

SELECTION CRITERIA

We included randomised trials, non-randomised trials, controlled before-after studies, and interrupted time series. Eligible studies described interventions affecting prescribing aimed at improving appropriate polypharmacy in people aged 65 years and older, prescribed polypharmacy (four or more medicines), which used a validated tool to assess prescribing appropriateness. These tools can be classified as either implicit tools (judgement-based/based on expert professional judgement) or explicit tools (criterion-based, comprising lists of drugs to be avoided in older people).

DATA COLLECTION AND ANALYSIS

Two review authors independently reviewed abstracts of eligible studies, extracted data and assessed risk of bias of included studies. We pooled study-specific estimates, and used a random-effects model to yield summary estimates of effect and 95% confidence intervals (CIs). We assessed the overall certainty of evidence for each outcome using the GRADE approach.

MAIN RESULTS

We identified 32 studies, 20 from this update. Included studies consisted of 18 randomised trials, 10 cluster randomised trials (one of which was a stepped-wedge design), two non-randomised trials and two controlled before-after studies. One intervention consisted of computerised decision support (CDS); and 31 were complex, multi-faceted pharmaceutical-care based approaches (i.e. the responsible provision of medicines to improve patient's outcomes), one of which incorporated a CDS component as part of their multi-faceted intervention. Interventions were provided in a variety of settings. Interventions were delivered by healthcare professionals such as general physicians, pharmacists and geriatricians, and all were conducted in high-income countries. Assessments using the Cochrane 'Risk of bias' tool, found that there was a high and/or unclear risk of bias across a number of domains. Based on the GRADE approach, the overall certainty of evidence for each pooled outcome ranged from low to very low.It is uncertain whether pharmaceutical care improves medication appropriateness (as measured by an implicit tool), mean difference (MD) -4.76, 95% CI -9.20 to -0.33; 5 studies, N = 517; very low-certainty evidence). It is uncertain whether pharmaceutical care reduces the number of potentially inappropriate medications (PIMs), (standardised mean difference (SMD) -0.22, 95% CI -0.38 to -0.05; 7 studies; N = 1832; very low-certainty evidence). It is uncertain whether pharmaceutical care reduces the proportion of patients with one or more PIMs, (risk ratio (RR) 0.79, 95% CI 0.61 to 1.02; 11 studies; N = 3079; very low-certainty evidence). Pharmaceutical care may slightly reduce the number of potential prescribing omissions (PPOs) (SMD -0.81, 95% CI -0.98 to -0.64; 2 studies; N = 569; low-certainty evidence), however it must be noted that this effect estimate is based on only two studies, which had serious limitations in terms of risk bias. Likewise, it is uncertain whether pharmaceutical care reduces the proportion of patients with one or more PPOs (RR 0.40, 95% CI 0.18 to 0.85; 5 studies; N = 1310; very low-certainty evidence). Pharmaceutical care may make little or no difference in hospital admissions (data not pooled; 12 studies; N = 4052; low-certainty evidence). Pharmaceutical care may make little or no difference in quality of life (data not pooled; 12 studies; N = 3211; low-certainty evidence). Medication-related problems were reported in eight studies (N = 10,087) using different terms (e.g. adverse drug reactions, drug-drug interactions). No consistent intervention effect on medication-related problems was noted across studies.

AUTHORS' CONCLUSIONS

It is unclear whether interventions to improve appropriate polypharmacy, such as reviews of patients' prescriptions, resulted in clinically significant improvement; however, they may be slightly beneficial in terms of reducing potential prescribing omissions (PPOs); but this effect estimate is based on only two studies, which had serious limitations in terms of risk bias.

Antipsychotic Drug Dispensations in Older Adults, Including Continuation After a Fall-Related Hospitalization: Identifying Adherence to Screening Tool of Older Persons' Potentially Inappropriate Prescriptions Criteria Using the Nova Scotia Seniors' Pharmacare Program and Canadian Institute for Health's Discharge Databases

Purpose

Despite well-established concerns regarding adverse drug effects, antipsychotics are frequently prescribed for older adults. Our first objective was to identify trends in antipsychotic dispensations to older Nova Scotians. STOPP (Screening Tool of Older Persons’ Potentially Inappropriate Prescriptions) criteria identify antipsychotic use in those with a history of falls as potentially inappropriate. Our second objective was to identify trends, predictors, and adherence with this STOPP criteria by identifying continued antipsychotic dispensations following a fall-related hospitalization.

Methods

A descriptive cross-sectional cohort study of Nova Scotia Seniors’ Pharmacare Program (NSSPP) beneficiaries ≥ 66 years with at least one antipsychotic dispensation annually from April 1, 2009 to March 31, 2014 was completed. As well, unique beneficiaries with at least one antipsychotic dispensation in the four-year period between April 1, 2009 and March 31, 2013 were linked to fall-related hospitalizations recorded in the Canadian Institute for Health Information Discharge Abstract Database. The relationship of age, sex, fiscal year, days supply and length-of-stay were studied to identify predictors of continued antipsychotic dispensation post-discharge. Descriptive statistics and multivariate logistic analysis were performed. Odds ratios for the association of risk factors and adherence to STOPP criteria were calculated.

Findings

We identified that in each year observed, there were 6% of eligible NSSPP beneficiaries that received at least one antipsychotic dispensation. Approximately 70% of antipsychotic dispensations were for second generation agents, primarily quetiapine and risperidone. Of the unique beneficiaries with at least one antipsychotic dispensation in the four-year period between April 1, 2009 and March 31, 2013 who survived a fall-related hospitalization over 75% were dispensed an antipsychotic in the 100 days following hospital discharge. Logistic regression showed no statistically significant association between potentially inappropriate therapy and potential predictors in multivariate analysis.

Implications

In each year from 2009 to 2014, 6% of Nova Scotia Seniors’ Pharmacare beneficiaries were dispensed at least one antipsychotic prescription. Over 75% of the older adults who received an antipsychotic dispensation in the 100 days prior to a fall-related hospitalization, continued the drug class after discharge. This demonstrates that despite the recommendations of quality indicators such as the STOPP criteria, antipsychotics are continued in individuals at a high risk of falling. Future investigations are needed to inform health team, system, and policy interventions to improve concordance with this antipsychotic specific STOPP criterion when appropriate.

Prescription Changes During Geriatric Care Episodes: A Trend Analysis Conducted in Sweden

BACKGROUND

The number of drugs prescribed for old people has been rising in recent decades. With increasing age and multiple medications, the risk of complications and drug prescription complexity increases. Multiple changes to prescriptions could be a factor that improves treatment quality.

OBJECTIVES

Our objective was to investigate trends in drug prescriptions and factors that contribute to prescription changes. Specific objectives were to find out whether high numbers of prescription changes are significantly correlated with age, sex, comorbidity, length of care episode, and number of drugs.

METHODS

Data were extracted from geriatric clinic records in Stockholm in 2005, 2010, and 2015. Indicators for good drug therapy were used to assess the effects of prescription changes on quality, using an index of inappropriate drug use (IDU). Data were analyzed with Student's t-test, PR test, Wilcoxon's rank sum test, and linear regression.

RESULTS

Patients had more comorbidities and used more drugs but had shorter hospital stays and significantly fewer prescription changes in 2015 than in 2005. Length of care episode was significantly associated with prevalence of prescription changes. Our model showed that, for each day by which the length of care episode decreased, the number of prescription changes decreased by 8%. The number of prescription changes was negatively correlated to the IDU index score.

CONCLUSIONS

The study showed that more prescription changes were associated with longer care episodes and improved drug prescribing quality as per the IDU index. Given prescription changes are regarded as a quality factor in geriatric care, quality may have decreased along with the length of care episodes between 2005 and 2015.

Pharmacist comprehensive review of treatment compared with STOPP-START criteria to detect potentially inappropriate prescription in older complex patients

OBJECTIVES

To compare potentially inappropriate prescribing (PIP) according to the clinical judgement of the pharmacist with PIP according to explicit STOPP-START criteria in institutionalised and hospitalised patients with multiple pathologies. To describe and compare the main pharmacological groups involved and determine the factors associated with the detection of PIP in these patients.

METHOD

A prospective multicentre observational study of institutionalised and hospitalised multipathology patients aged >65 years. A specialised pharmacist used his best clinical judgement to detect PIP based on a comprehensive review of the complete chronic treatment of patients, which is an essential activity in interdisciplinary care. STOPP-START criteria were used as an aid tool to detect PIP. The main variable was the number of PIP incidents detected.

RESULTS

Detected PIP incidents were analysed in 338 patients. Clinical judgement detected more PIP incidents (35%) than did STOPP-START criteria. More PIP incidents unrelated to these criteria were detected in institutionalised patients than in hospitalised patients. Clinical judgement mainly detected PIP incidents related to incorrect doses and drug interactions (p<0.001); however, STOPP-START criteria mainly detected PIP incidents related to drug duplication and insufficiently treated diagnosis or symptoms (p=0.001 and p<0.001). In total, 93.8% of the PIP incidents were detected in polypharmacy patients (≥5 drugs). Institutionalised and high-level polypharmacy (≥10 drugs) patients were at the highest risk of PIP.

CONCLUSIONS

A large number of PIP incidents were detected in institutionalised and hospitalised patients with multiple pathologies. The inclusion of a pharmacist in the multidisciplinary team facilitated the detection of PIP incidents, particularly in the institutionalised population and patients treated with high-level polypharmacy which were not detected by explicit STOPP-START criteria.

Extent and quality of drug use in community-dwelling people aged ≥75 years: A Swedish nationwide register-based study

Aims: It is important for district nurses and other health professionals in primary care to gain more insight into the patterns and quality of drug use in community-dwelling older people, particularly in 75-year-olds, who have been the target of preventive home visits. This study aimed to examine the extent and quality of drug use in community-dwelling older people and to compare drug use in 75-year-olds with that of older age groups. Methods: Data from 2013 on people aged ≥75 years were obtained from the Swedish Prescribed Drug Register. Those living in the community (671,940/739,734 people aged ≥75 years) were included in the study. Quality of drug use was assessed by using a selection of indicators issued by the Swedish National Board of Health and Welfare. Results: The prevalence of polypharmacy and of many drug groups increased with age, as did several indicators of inappropriate drug use. However some drug groups, as well as inappropriate drugs, were prevalent in 75-year-olds and declined with age, for example diabetes drugs, drugs with major anticholinergic effects and nonsteroidal anti-inflammatory drugs. Conclusions: The substantial use of some drugs as early as 75 years of age confirms the value of including drug use as a topic in preventive home visits to 75-year-olds. The finding that polypharmacy and many measures of inappropriate drug use increased with age in community-dwelling older people also underscores the importance of district nurses' role in continuing to promote safe medication management at higher ages.

Prevalence and predictors of potentially inappropriate prescribing of central nervous system and psychotropic drugs among elderly patients: A national population study in Korea

OBJECTIVES

To investigate the prevalence of potentially inappropriate prescribing (PIP) of central nervous system and psychotropic (CNS-PS) drugs to the Korean elderly population, and to identify PIP-associated factors.

METHODS

Ambulatory care visits were identified from the 2013 National Aged Patient Sample (HIRA-APS-2013) data, composed of 20% random samples of all enrollees in the universal health security program aged ≥65 years. The CNS-PS section of Screening Tool of Older Person's potentially inappropriate Prescriptions (STOPP) criteria version 2 was used to identify PIP at these visits.

RESULTS

A total of 24,427,069 prescription claims records and 1,122,080 patients were included in the study; 10.73% of the claims and 53.64% of the patients satisfied at least one STOPP criterion in the prescription of CNS-PS drugs. The highest prevalence of PIP was observed for the criteria of "first-generation antihistamines" (FGAH), followed by tricyclic antidepressants (TCA) in patients with prostatism and TCA in patients with dementia. The generalized estimating equation logistic regression analysis showed that the PIP of FGAH was significantly associated with polypharmacy (5-9 drugs: odds ratio (OR) 4.965, 95% confidence interval (CI) 4.936-4.994; ≥10 drugs: OR 5.704, 95% CI 5.604-5.807), less severe health conditions (Charlson Comorbidity Index (CCI)=2: OR 0.852, 95% CI 0.842-0.862; CCI=1: OR 0.975, 95% CI 0.964-0.986), prescriptions from clinics (OR>1.0), and outpatient care by general practitioners (OR>1.0).

CONCLUSIONS

Appropriate interventions to reduce PIP should be made, especially for the criteria that indicate a high PIP prevalence. Targeted strategies are necessary to modify the risk factors of PIP identified from this study.

Educational intervention on medication reviews aiming to reduce acute healthcare consumption in elderly patients with potentially inappropriate medicines-A pragmatic open-label cluster-randomized controlled trial in primary care

PURPOSE

Potentially inappropriate medicines (PIMs) may cause 10% of unplanned admissions in elderly people. We performed an educational intervention in primary care to reduce acute health care consumption and PIMs through the promotion of medication reviews (MRs) in elderly patients.

METHODS

This cluster-randomized controlled trial was conducted in the context of an official campaign promoting rational drug use in elderly people. Sixty-nine primary health care practices with 119,910 patients aged older than or equal to 65 were randomized, with 1 dropout in the intervention group. The intervention consisted of educational outreach visits with feedback on prescribing and the development of a working procedure on MRs. Follow-up was 9 months. Outcomes were assessed in an administrative health care database. The combined primary outcome was unplanned hospital admission and/or emergency department visit. Secondary outcomes were among other PIMs and rates of MRs. The risk differences in outcomes between intervention and control group were estimated by using regression models.

RESULTS

During follow-up, 22.8% of patients in the intervention and 22.0% in the control group were admitted unplanned to hospital and/or experienced at least 1 emergency department (nonsignificant risk difference 0.8%, 95% CI -0.7% to 2.4%). There were no significant differences regarding secondary outcomes such as PIMs or MRs.

CONCLUSIONS

No changes were seen in acute health care consumption, PIMs, and MRs in elderly patients after an educational intervention in primary care. The reasons for the lack of effect could be a suboptimal intervention, limitations in outcome measures, and the use of administrative data to monitor outcomes.

Clinically relevant potential drug-drug interactions among outpatients: A nationwide database study

BACKGROUND

Adverse drug events due to drug-drug interactions (DDIs) represent a considerable public health burden, also in Slovenia. A better understanding of the most frequently occurring potential DDIs may enable safer pharmacotherapy and minimize drug-related problems.

OBJECTIVES

The aim of this study was to evaluate the prevalence and predictors of potential DDIs among outpatients in Slovenia.

METHODS

An analysis of potential DDIs was performed using health claims data on prescription drugs from a nationwide database. The Lexi-Interact Module was used as the reference source of interactions. The influence of patient-specific predictors on the risk of potential clinically relevant DDIs was evaluated using logistic regression model.

RESULTS

The study population included 1,179,803 outpatients who received 15,811,979 prescriptions. The total number of potential DDI cases identified was 3,974,994, of which 15.6% were potentially clinically relevant. Altogether, 9.3% (N = 191,213) of the total population in Slovenia is exposed to clinically relevant potential DDIs, and the proportion is higher among women and the elderly. After adjustment for cofactors, higher number of medications and older age are associated with higher odds of clinically relevant potential DDIs. The burden of DDIs is highest with drug combinations that increase risk of bleeding, enhance CNS depression or anticholinergic effects or cause cardiovascular complications.

CONCLUSION

The current study revealed that 1 in 10 individuals in the total Slovenian population is exposed to clinically relevant potential DDIs yearly. Taking into account the literature based conservative estimate that approximately 1% of potential DDIs result in negative health outcomes, roughly 1800 individuals in Slovenia experience an adverse health outcome each year as a result of clinically relevant potential interactions alone.

Demographic and Socioeconomic Characteristics of Outpatients Could Modify Their Attitude Towards Misusing Medications in Northern Jordan

Background

Potentially inappropriate drug use, including prescribed and over-the-counter medications, is associated with increased morbidity and mortality. It also contributes to unnecessary expenditure on health services. This survey was undertaken to investigate the incidence of drug misuse and associated socioeconomic/demographic characteristics in Irbid, Jordan.

Design and Methods

The present cross section study was conducted using a validated 5-point Likert scale questionnaire to be self-reported by 480 outpatients visiting clinics in three major medical centres in Irbid, Jordan between 20th October 2015 and 27th November 2015. Descriptive analysis, chi-square tests and ordinal logistic regression models were performed.

Results

Patients demonstrated distinctive attitudes towards medication misuse (P<0.001). Whereas around 40% of patients sometimes stopped taking medications earlier than prescribed or doubled the dose in case of missing a dose, three quarters and two fifth of participants neither used expired drugs nor continued to take a drug when adverse drug reactions occurred, respectively. Also, there were significant associations (P<0.05) between patients’ attitudes towards misusing medications and characteristics like age, gender, income and marital status. For instance, senior patients (>45 years) tended to double a medication’s dose in case of no improvement, and to use others’ leftover drugs without medical supervision. Further, male and female patients exhibited different attitude towards misusing medications. Unemployment and little earnings increased the risk for not using drugs properly. Furthermore, married patients were less likely to misuse medications. In particular, the educational level of patients was found to play a major role in modifying patients’ attitudes towards potentially inappropriate drug use. Patients holding one or more university degrees were at lower risk for using medications inappropriately.

Conclusions

This survey indicated that northern Jordanians inappropriately used medications to a great extent, suggesting that the current policies should be revised, and emphasising the importance of running public antidrug misuse awareness campaigns and establishing advanced educational/training events targeting healthcare professionals.

The Association of Potentially Inappropriate Medication at Older Age With Cardiovascular Events and Overall Mortality: A Systematic Review and Meta-Analysis of Cohort Studies

OBJECTIVE

The aim of this systematic review was to identify, evaluate, and meta-analyze cohort studies reporting the association of potentially inappropriate medication (PIM) intake with mortality and cardiovascular events.

DESIGN

A systematic review and meta-analysis of prospective and retrospective cohort studies were conducted. Study appraisal included a thorough risk of bias assessment. Data synthesis followed a random-effects model.

DATA SOURCES

The included studies were retrieved from the databases MEDLINE and ISI Web of Knowledge. Additionally, the authors checked the references of the included studies for further relevant literature.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

For inclusion in a study, the population needed to be older than 60 years of age and not restricted to having one specific disease. The outcome had to address all-cause mortality or cardiovascular events. Studies that examined polypharmacy or specific drugs were excluded.

RESULTS

At first, 13 studies were included in a meta-analysis. The association of PIM with overall mortality was not statistically significant (risk ratio; 95% confidence interval, 1.13; 0.95-1.35). However, the majority of studies showed a high risk of specific forms of bias. These biases can be excluded by applying a new user design. It ascertains that adverse events occurring early in therapy are recorded. After restricting the meta-analysis to three studies with a new user design, the association of PIM use and mortality was statistically significant (risk ratio; 95% confidence interval, 1.59; 1.45-1.75). Only one study focused on cardiovascular events and found no statistically significant association. However, the study was not conducted with a new user design.

CONCLUSION

In studies with adequate methods (new user design), PIM use, defined by Beers criteria or the HEDIS-DAE list, was associated with a 1.6-fold increased mortality in older adults. Physicians should therefore avoid prescribing PIM for older adults whenever feasible. Further new user design studies are required for cardiovascular outcomes and to compare the predictive value of different PIM criteria for mortality.

Influence of Incipient Dementia on Hospitalization for Primary Care Sensitive Conditions: A Population-Based Cohort Study

BACKGROUND

Studies have reported that moderate/severe stages of dementia are linked to increased hospitalization rates, but little is known about the influence of incipient dementia on hospitalizations for primary care sensitive conditions (PCSCs).

OBJECTIVE

To examine the associations between incipient dementia and hospitalization outcomes, including all-cause and PCSC hospitalization.

METHODS

A total of 2,268 dementia-free participants in the Swedish National study on Aging and Care-Kungsholmen were interviewed and clinically examined at baseline. Participants aged ≥78 years were followed for 3 years, and those aged 60-72 years, for 6 years. Number of hospitalizations was retrieved from the National Patient Register. Dementia was diagnosed in accordance with Diagnostic and Statistical Manual of Mental Disorders-IV criteria. Hospitalization outcomes were compared in participants who did and did not develop dementia. Zero-inflated Poisson regressions and logistic regressions were used in data analysis.

RESULTS

During the follow-up, 175 participants developed dementia. The unadjusted PCSC admission rate was 88.2 per 1000 person-years in those who developed dementia and 25.6 per 1000 person-years in those who did not. In the fully adjusted logistic regression model, incipient dementia was associated with an increased risk of hospitalization for PCSCs (OR = 2.3, 95% CI 1.3-3.9) but not with the number of hospitalizations or with all-cause hospitalization. Risks for hospitalization for diabetes, congestive heart failure, and pyelonephritis were higher in those who developed dementia than in those who did not. About 10% participants had a PCSC hospitalization attributable to incipient dementia.

CONCLUSION

People with incipient dementia are more prone to hospitalization for PCSCs but not to all-cause hospitalization.

Clinical relevance of the STOPP/START criteria in hip fracture patients

Purpose

The aim of this study was to investigate the clinical relevance of potentially inappropriate medications (PIMs), identified by the STOPP criteria, and potential prescribing omissions (PPOs), identified by the START criteria, and to identify predictors for clinically relevant PIMs and PPOs.

Methods

The STOPP and START criteria were applied on the medication lists of 200 older hip fracture patients, consecutively recruited to a randomized controlled study in 2009. For each identified PIM and/or PPO, the clinical relevance was assessed at the individual level, using medical records from both hospital and primary care as well as data collected in the original study.

Results

A total of 555 PIMs/PPOs were identified in 170 (85%) patients (median age: 85 years, 67% female), 298 (54%) of which, in 141 (71%) patients, were assessed as clinically relevant. A greater proportion of PIMs than PPOs were clinically relevant: 71% (95% CI: 66%; 76%) vs. 32% (27%; 38%). A greater proportion of PPOs than PIMs could not be assessed with available information: 38% (32%; 44%) vs. 22% (17%; 27%). Number of drugs and multidose drug dispensing, but not age, sex, cognition, or nursing home residence, were associated with ≥1 clinically relevant PIMs/PPOs.

Conclusions

The present study illustrates that one in two PIMs/PPOs identified by the STOPP/START criteria is clearly clinically relevant, PIMs being clinically relevant to a greater extent than PPOs. Based on available information, the clinical relevance could not be determined in a non-negligible proportion of PIMs/PPOs. Number of drugs and multidose drug dispensing were associated with ≥1 clinically relevant PIMs/PPOs.

Multicompartment compliance aids in the community: the prevalence of potentially inappropriate medications

AIMS

To assess the prevalence of potentially inappropriate medications (PIMs) use in a population of community-based multicompartment compliance aid (MCA) users in north-east Scotland.

METHODS

Data for MCAs dispensed by 48 of the 50 community pharmacies in Aberdeen City between 1^st June to 31^st October 2014, together with concurrently prescribed medications, patient demographics and Carstairs index of social deprivation were recorded. Drug-specific quality indicators for PIMs from the Swedish National Board of Health and Welfare were applied and bivariate logistic regression analysis used to assess for associations with demographic variables.

RESULTS

The median age was 82 years (range 12-105 years, 59% female). A total of 1977 PIMs were identified affecting 57.8% of patients. A quarter of patients were prescribed ≥10 medications and 43% had a prescription containing at least one clinically significant drug-drug interaction (DDI). Ten drug groups accounted for 76% of all DDIs. A significant increase in the risk for at least one PIM was associated with female sex (for all indicators of PIM use), age <80 years (three or more psychotropic medicines [OR 5.88, 2.96-11.70, P < 0.001]) and lower socioeconomic status (prescription of ≥10 medications [OR: 1.43, 95% CI: 1.16-1.78], prescription of a long-acting benzodiazepine [OR: 1.84, CI: 1.14-2.98]).

CONCLUSIONS

MCA use is associated with a significant incidence of PIMs particularly affecting those younger than 80 years and those living in deprived areas. Our findings indicate the need for a more aggressive multidisciplinary approach to the review of the medications prescribed to MCA users.

Managing multimorbidity in primary care in patients with chronic respiratory conditions

The term multimorbidity is usually defined as the coexistence of two or more chronic conditions within an individual, whereas the term comorbidity traditionally describes patients with an index condition and one or more additional conditions. Multimorbidity of chronic conditions markedly worsens outcomes in patients, increases treatment burden and increases health service costs. Although patients with chronic respiratory disease often have physical comorbidities, they also commonly experience psychological problems such as depression and anxiety. Multimorbidity is associated with increased health-care utilisation and specifically with an increased number of prescription drugs in individuals with multiple chronic conditions such as chronic obstructive pulmonary disease. This npj Primary Care Respiratory Medicine Education Section case study involves a patient in a primary care consultation presenting several common diseases prevalent in people of this age. The patient takes nine different drugs at this moment, one or more pills for each condition, which amounts to polypharmacy. The problems related with polypharmacy recommend that a routine medication review by primary care physicians be performed to reduce the risk of adverse effects of polypharmacy among those with multiple chronic conditions. The primary care physician has the challenging role of integrating all of the clinical problems affecting the patient and reviewing all medicaments (including over-the-counter medications) taken by the patient at any point in time, and has the has the key to prevent the unwanted consequences of polypharmacy. Multimorbid chronic disease management can be achieved with the use of care planning, unified disease templates, use of information technology with appointment reminders and with the help of the wider primary care and community teams.
