Abuse/Misuse of Prescription Medications in Older Adults

The world population is aging due to increasing life expectancy. The rate of drug use increases, and inappropriate prescribing is frequently encountered with advancing age. In addition, misuse and abuse of prescription drugs is a serious problem in older adults. It is challenging to detect substance and drug abuse in older patients because it may have fewer consequences in social, legal, and occupational fields. However, there is not enough information about the screening, evaluation, diagnosis, and treatment of abuse. Therefore, the awareness of health care professionals and others involved in older patients' care should be raised about the misuse and abuse of drugs.

[Development of a tool to help optimizing drug prescriptions in pediatric units in Côte d'Ivoire: GOPP tool]

OBJECTIVE

This study aims to develop a tool for optimizing drug management related to clinical and therapeutic contexts of pediatric units in Côte d'Ivoire.

METHODOLOGY

A list of Inappropriate prescribings (IPs) was developed from prescription review of inpatients and outpatients aged 1 month to 15 years and followed in pediatric units at 4 Teaching Hospitals of Abidjan during 16 months. A two-round Delphi method was used to validate a qualitative list of IPs by experts according to their level of agreement on a six-point Likert scale of 0-5 (0, no opinion; 5, strongly agree). Only propositions obtaining the agreement (rating 4 or 5) of>70% of experts who gave a non-zero rating for the first round and 80% for the second round were retained. Each IP of final list associated with "rationale", (justifying the inappropriateness of prescribing), and "recommendations and/or therapeutic alternative", used to elaborate items of a tool for helping to optimize drug prescriptions in pediatrics (GOPP tool).

RESULTS

A qualitative list of 54 IPs was drawn up from 267 Drug related problems detected after prescription review of 4992 prescription lines for 881 patients. Twenty-three (23) experts rated IPs on this list during two-round Delphi survey. At the end of survey, final list of 52 IPs was retained for development GOPP tool items. Malaria (15%), rhinitis (12%) and bacterial infectious (8%) are mainly pathologies concerned by these items.

CONCLUSION

GOPP tool developed in this study should help to improve drug management of patients in pediatric units in Côte d'Ivoire.

Intervention elements and behavior change techniques to improve prescribing for older adults with multimorbidity in Singapore: a modified Delphi study

PURPOSE

Potentially inappropriate prescribing among older adults is a rising concern, attributed mainly by polypharmacy and multimorbidity. We aimed to identify key components and strategies for construction of a context-relevant intervention to facilitate appropriate prescribing in outpatient clinics in Singapore.

METHODS

The modified Delphi study was conducted in two rounds with 20 geriatricians from seven public hospitals in Singapore. Round one survey presented 69 statements formulated from a scoping review, while round two presented 23 statements with some modifications based on round one comments. The statements were rated against a 7-point Likert scale on their importance and impact on prescribing for older adults with multimorbidty.

RESULTS

Consensus were achieved for 90% of the statements. Seven intervention elements were identified as being important: medication review, training, medication therapy management, shared decision making, patient interview, medication reconciliation, comprehensive geriatric assessment. In addition, some commonly identified behavior change techniques included goal setting (behavior), goal setting (outcome) and problem solving.

CONCLUSIONS

This study identified important intervention elements and their potential strategies that could be adopted in an intervention to optimize appropriate prescribing for older adults with multimorbidity.

Potentially inappropriate prescribing in a falls clinic using the STOPP and START criteria

Background Potentially inappropriate prescribing is increasingly common in older patients with falls. However, published indicators to assess inappropriate prescribing remains unestablished in many countries. Objective This study determined the burden and profile of potentially inappropriate prescribing among patients attending a falls clinic using the STOPP/START criteria and evaluated the factors for falls potentially associated to inappropriate prescribing. Setting University of Malaya Medical Centre Falls Clinic. Method Data of individuals aged ≥ 65 years referred to the falls and syncope clinic were extracted from the falls registry. Potentially inappropriate prescribing was determined with the STOPP/START version 2 criteria. The relationship between potentially inappropriate prescribing with polypharmacy (≥ 5 medications), comorbidities and clinical variables were determined using Pearson's chi-square and potential confounders adjusted for with multivariate regression. Main outcome measure Potentially inappropriate medicines and/or omitted medicines using STOPP/START criteria. Results Data from 421 individuals, aged 77.8 ± 6.7 years and 53.4% women, were included. Potentially inappropriate prescribing was present in 311 (73.9%). Potentially inappropriate medicines use accounted for 84.6% of the 325 prescriptions. 361/659 instances (54.8%) were falls-risk-increasing drugs, with vasodilators (49.3%) being the main potentially inappropriate medicine identified. Of the 177/421 with polypharmacy, 169/177 (95.5%) were exposed to ≥ one potentially inappropriate medicine. 129 instances of potentially omitted medicines were observed in 109 prescriptions (25.9%). Conclusion STOPP/START criteria are useful to identify potentially inappropriate prescribing at the falls and syncope clinic. This finding has important implications for medication review strategies at falls clinic. Future research should determine whether identifying potentially inappropriate prescribing may reduce adverse falls outcomes among patients in this setting.

Sex Differences in Characteristics Associated with Potentially Inappropriate Medication Use and Associations with Functional Capacity in Older Participants of the Berlin Aging Study II

INTRODUCTION

Medication safety is a vital aim in older adults' pharmacotherapy. Increased morbidity and vulnerability require particularly careful prescribing. Beneath avoiding unnecessary polypharmacy and prescribing omissions, physicians have to be aware of potentially inappropriate medications (PIMs) and related outcomes to optimize older adults' drug therapy, and to reduce adverse drug events.

OBJECTIVE

The aim of this study was to identify participants characteristics associated with PIM use and associations of PIM use with functional capacity with a focus on sex differences.

METHODS

Multivariable logistic regression analyses of cross-sectional Berlin Aging Study II (BASE-II) data (N = 1,382, median age 69 years, interquartile range 67-71, 51.3% women) were performed with PIM classification according to the EU(7)-PIM list.

RESULTS

In the overall study population, higher education was associated with lower odds of PIM use (odds ratio [OR] 0.93, confidence interval [CI] 95% 0.87-0.99, p = 0.017). Falls (OR 1.53, CI 95% 1.08-2.17, p = 0.016), frailty/prefrailty (OR 1.68, 1.17-2.41, p = 0.005), and depression (OR 2.12, CI 95% 1.32-3.41, p = 0.002) were associated with increased odds of PIM use. A better nutritional status was associated with lower odds of PIM use (OR 0.88, CI 95% 0.81-0.97, p = 0.008). In the sex-stratified analysis, higher education was associated with lower odds of PIM use in men (OR 0.90, CI 95% 0.82-0.99, p = 0.032). Frailty/prefrailty was associated with increased odds of PIM use in men (OR 2.04, CI 95% 1.18-3.54, p = 0.011) and a better nutritional status was associated with lower odds of PIM use in men (OR 0.83, CI 95% 0.72-0.96, p = 0.011). Falls in the past 12 months were related to an increased prevalence of PIM use in women (OR 1.74, CI 95% 1.10-2.75, p = 0.019). Depression was associated with a higher prevalence of PIM use in both men (OR 2.74, CI 95% 1.20-6.24, p = 0.016) and women (OR 2.06, CI 95% 1.14-3.71, p = 0.017). We did not detect sex differences regarding the overall use of drugs with anticholinergic effects, but more men than women used PIMs referring to the cardiovascular system (p = 0.036), while more women than men used PIMs referring to the genitourinary system and sex hormones (p < 0.001).

CONCLUSION

We found similarities, but also differences between men and women as to the associations between PIM use and participants' characteristics and functional capacity assessments. The association of lower education with PIM use may suggest that physicians' prescribing behavior is modified by patient education, a relationship that could evolve from more critical attitudes of educated patients towards medication use. We conclude that sex differences in associations of PIM use with functional capacities might be partly attributable to sex differences in drug classes used, but not with regard to anticholinergics, as these are used to a similar extent in men and women in the cohort studied here.

The impact of PIPs on mortality and readmissions in older adults: a retrospective cohort study

PURPOSE

Our aim was to determine the impact of potentially inappropriate prescriptions (PIP), according to "Screening Tool of Older Persons' Prescriptions" criteria version 2 (STOPP-2), on mortality and hospital admissions.

METHODS

Monocentric retrospective cohort study. Patients over 65 years of age and who were consecutively discharged from internal medicine at a Spanish university hospital in 2016 were included. The mortality and hospital admissions of the cohort of patients were analysed using their electronic health records within two years from the time of discharge. Analysis was done based on the type and number of STOPP-2 criteria as well as taking into account the total number of medications. The subdistribution hazard ratios (SHR) were estimated through a competing proportional hazards model.

RESULTS

A total of 270 patients with a median age of 82 years (interquartile range/IQR 76-86 years), and 152 (56.3%) women were studied. It was found out that 28.3% of patients with PIP died compared to 17.2% of patients without it. Digoxin (B1 STOPP-2 criterion) with a subdistribution hazard ratio (SHR) 2.40 (95% CI 0.63-9.18), selective serotonin re-uptake inhibitors/SSRIs (D4) with a SHR 1.76 (95% CI 0.52-5.96) and neuroleptic drugs (K2) with a SHR 2.01 (95% CI 0.82-4.95) non-significantly increased the risk of death. Dementia (SHR 5.45; 95% CI 2.76-10.78) was then the only statistically significant risk factor for death. Sixty percent of patients with a PIP had shown at least one hospital admission compared to 51% of patients without it. The number of drugs at discharge (SHR 1.03; 95% CI 1.01-1.05) and having 1-2 STOPP-2 criteria (SHR 1.17; 95% CI 1.02-1.35) significantly increased the risk of hospital admission.

CONCLUSION

The number of drugs at discharge and having any STOPP criteria significantly increased the risk of hospital admission in this cohort. PIP, only according to some specific STOPP-2 criteria involving digoxin, neuroleptics and SSRIs, might associate with a statistically non-significantly higher risk on mortality.

Improving medication adherence and effective prescribing through a patient-centered prescription model in patients with multimorbidity

PURPOSE

This study aimed to assess the impact of the patient-centered prescription (PCP) model in medication adherence and effective prescribing in patients with multimorbidity.

METHODS

Uncontrolled before-after study in an intermediate care facility in a mixed urban-rural district. Inpatients aged ≥ 65 years with multimorbidity exposed to polypharmacy before hospital admission were consecutively enrolled. Every patient's treatment plan was analyzed through the PCP model, which includes interventions aimed at improving medication adherence. The primary endpoint was the change in the proportion of adherent patients between pre-admission and after discharge for all regularly scheduled long-term medications, using the proportion of days covered (PDC). Secondary endpoints included the change on mean PDC for all long-term medications, number of long-term medications, proportion of patients with hyperpolypharmacy, medication regimen complexity index (MRCI) score, drug burden index (DBI) score, number of potential inappropriate prescribing (PIP), and proportion of patients with ≥ 2 PIPs.

RESULTS

Ninety-three non-institutionalized patients were included (mean age 83.0 ± SD 6.1 years). The proportion of adherent patients increased from 22.1 to 51.9% (P < 0.001). Intervention also improved mean PDC [mean difference (95% CI) 10.6 (7.7, 13.5)] and effective prescribing through a reduction on the number of long-term medications [- 1.3 (- 1.7, - 0.9)], proportion of patients exposed to hyperpolypharmacy (- 16.1%, P < 0.001), MRCI score [- 2.2 (- 3.4, - 1.0)], DBI score [- 0.16 (- 1.8, - 1.3)], number of PIPs [- 1.6 (- 1.8, - 1.3)], and proportion of patients with ≥ 2 PIPs (- 53.7%, P < 0.001).

CONCLUSION

Studied intervention provides significant effective prescribing and medication adherence enhancements in non-institutionalized older patients with multimorbidity and polypharmacy.

Antimicrobial stewardship in rural and remote primary health care: a narrative review

BACKGROUND

Antimicrobial resistance is an emerging problem worldwide and poses a significant threat to human health. Antimicrobial stewardship programmes are being implemented in health systems globally, primarily in hospitals, to address the growing threat of antimicrobial resistance. Despite the significance of primary health care services in providing health care to communities, antimicrobial stewardship programmes are not well established in this sector, especially in rural and remote settings. This narrative review aims to identify in rural and remote primary health care settings the (1) correlation of antimicrobial resistance with antibiotic prescribing and volume of antibiotic use, (2) appropriateness of antimicrobial prescribing, (3) risk factors associated with inappropriate use/prescribing of antibiotics, and (4) effective antimicrobial stewardship strategies.

METHODS

The international literature was searched for English only articles between 2000 and 2020 using specified keywords. Seven electronic databases were searched: Scopus, Cochrane, Embase, CINAHL, PubMed, Ovid Medline and Ovid Emcare. Publication screening and analysis were conducted using Joanna Briggs Institute systematic review tools.

RESULTS

Fifty-one eligible articles were identified. Inappropriate and excessive antimicrobial prescribing and use directly led to increases in antimicrobial resistance. Increasing rurality of practice is associated with disproportionally higher rates of inappropriate prescribing compared to those in metropolitan areas. Physician knowledge, attitude and behaviour play important roles in mediating antimicrobial prescribing, with strong intrinsic and extrinsic influences including patient factors. Antimicrobial stewardship strategies in rural and remote primary health care settings focus on health care provider and patient education, clinician support systems, utility of antimicrobial resistance surveillance, and policy changes. Results of these interventions were generally positive with decreased antimicrobial resistance rates and improved appropriateness of antimicrobial prescribing.

CONCLUSIONS

Inappropriate prescribing and excessive use of antimicrobials are an important contributor to the increasing resistance towards antimicrobial agents particularly in rural and remote primary health care. Antimicrobial stewardship programmes in the form of education, clinical support, surveillance, and policies have been mostly successful in reducing prescribing rates and inappropriate prescriptions. The narrative review highlighted the need for longer interventions to assess changes in antimicrobial resistance rates. The review also identified a lack of differentiation between rural and remote contexts and Indigenous health was inadequately addressed. Future research should have a greater focus on effective interventional components and patient perspectives.

Potentially inappropriate prescriptions: Associations with the health insurance contract and the quality of the patient-physician relationship?

CONTEXT

Potentially Inappropriate Prescriptions (PIP) are often used as an indicator of potential drug overuse or misuse to limit adverse drug events in older people.

OBJECTIVE

To determine whether PIP exposure differs as a function of the patient's health insurance scheme and the patient-physician relationship.

METHODS

Our dataset was collected from two surveys delivered to two cohorts of the Swiss Lc65+ study, together with a stratified random sample of older people in the Swiss canton of Vaud. The study sample consisted of 1,595 people aged 68 years and older living in the community and reporting at least one prescription drug. Logit regression models of PIP risk were run for various categories of variables: health related, socioeconomic, health insurance scheme and patient-physician relationship.

RESULTS

17% of our respondents had at least one PIP. Our results suggested that being enrolled in a health plan with restriction in the patient's choice of providers and having higher deductibles were associated with lower PIP risk. PIP risk did not differ as a function of the quality of the patient-physician relationship.

CONCLUSION

Our study helps to raise awareness about the organizational risk factors of PIP and, more specifically, how health insurance contracts could play a role in improving the management of drug consumption among community-dwelling older people.

The health impacts of preventive cardiovascular medication reduction on older populations: protocol for a systematic review and meta-analysis

BACKGROUND

Polypharmacy is inevitable and appropriate for many conditions, but in some cases, it can be problematic resulting in an increased risk of harm and reduced quality of life. There has been an increasing interest to reduce cardioprotective medications in older adults to potentially reduce the risk of harm due to treatment; however, there is no evidence on safety and efficacy to support this practice currently. This paper describes a protocol for a systematic review on the safety and efficacy of reducing cardioprotective medication in older populations.

METHODS

MEDLINE (PubMed), Embase (Ovid), and CENTRAL (Cochrane Central Register of Controlled Trials) will be searched from their inception onwards for relevant studies. Randomised controlled trials and non-randomised studies on interventions (prospective, retrospective cohort, case-control) conducted in older adults (75 years or older) examining reduction of cardioprotective medications will be included. The primary outcome of this study will be all-cause hospitalisation. Secondary outcome variables of interest are all-cause hospitalisation, mortality, quality of life, serious adverse events, major adverse cardiovascular events, falls, fractures, cognitive functioning, bleeding events, renal functioning, medication burden, drug reinstatement, time-in-hospital, and frailty status. Two reviewers will independently screen all citations, full-text articles, and extract data. Confidence in cumulative evidence will be assessed using the GRADE approach; the risk of bias will be assessed by the RoB-II tool for randomised controlled studies and ROBINS-I for non-randomised studies. Where sufficient data are available, we will conduct a random effects meta-analysis by combining the outcomes of the included studies. Sub-group analysis and meta-regression are planned to assess the potential harms and risks of different drug classes and the impacts in different patient populations (e.g. sex, cognitive status, renal status, and age).

DISCUSSION

The study will be a comprehensive review on all published articles identified using our search strategy on the safety and efficacy of cardioprotective medication reduction in the older population. The findings will be crucial to inform clinicians on potential health outcomes of reducing cardiovascular medication in the elderly.

REview of potentially inappropriate MEDIcation pr[e]scribing in Seniors (REMEDI[e]S): French implicit and explicit criteria

PURPOSE

To establish a consensus on both explicit and implicit criteria in order to identify potentially inappropriate prescribing (PIP) in French older people aged 75 years and over or 65 years and over with multimorbidity.

METHODS

Fifteen experts in geriatrics, general practice, pharmacy, and clinical pharmacology were involved in a two-round Delphi survey to assess preliminary explicit and implicit criteria based on an extensive literature review and up-to-date evidence data. Experts were asked to rate their level of agreement using a 5-level Likert scale for inclusion of criteria and also for rationale and therapeutic alternatives. A consensus was considered as reached if at least 75% of the experts rated criteria as "strongly agreed" or "agreed."

RESULTS

The new tool included a seven-step algorithm (implicit criteria) encompassing the three main domains that define PIP (i.e. overprescribing, underprescribing, and misprescribing) and 104 explicit criteria. Explicit criteria were divided into 6 tables related to inappropriate drug duplications (n = 7 criteria), omissions of medications and/or medication associations (n = 16), medications with an unfavourable benefit/risk ratio and/or a questionable efficacy (n = 39), medications with an unsuitable dose (n = 4) or duration (n = 6), drug-disease (n = 13), and drug-drug interactions (n = 19).

CONCLUSION

The REMEDI[e]S tool (REview of potentially inappropriate MEDIcation pr[e]scribing in Seniors) is an original mixed tool, adapted to French medical practices, aimed at preventing PIP both at the individual level in clinical practice and the population level in large-scale studies. Therefore, its use could contribute to an improvement in healthcare professionals' prescribing practices and safer care in older adults.

The inductor role of cardiac consultation in the pre-anesthetic evaluation of asymptomatic patients submitted to non-cardiac minor and intermediate-risk surgery: a cross-sectional study

INTRODUCTION

Asymptomatic patients with moderate functional capacity do not require Coronary Artery Disease (CAD) workup in the preoperative period of non-cardiac surgeries, especially when scheduled for minor and intermediate-risk surgeries. The workup is inappropriate because it promotes over diagnosing and pointless treatments. Moreover, those patients usually undergo cardiology assessment, in addition to pre-anesthetic evaluation.

OBJECTIVE

Investigate the role of cardiology consultation as mediator in inappropriate assessment of CAD for preoperative of non-cardiac surgeries.

METHOD

Retrospective study performed in a private anesthesia service using medical charts of asymptomatic patients with a history of controlled systemic disease and moderate functional capacity, submitted to pre-anesthetic consultation for minor and intermediate risk surgeries. Cardiology consultations were identified by the presence of a consultation report by a cardiologist. CAD workup was defined as undergoing cardiac stress tests.

RESULTS

We included 390 medical charts of patients with mean age of 48.6 ± 15.4 years, 67% women and 69% intermediate risk surgeries. CAD workup was infrequent and performed in 3.9% of patients. Besides, pre-anesthetic evaluation, 93 (24%) patients had a cardiology consultation. Among those patients, 15.1% were submitted to CAD workup, compared to 0.34% of patients without cardiology assessment (p < 0.001; RR = 4.4; 95% CI: 3.5-5.6).

CONCLUSIONS

Inappropriate testing for CAD investigation is infrequent for asymptomatic individuals submitted to minor and intermediate risk surgeries. However, cardiology consultation increases substantially the likelihood of a patient undergoing CAD workup, suggesting that, unlike the anesthesiologist, the cardiologist is a major mediator of this kind of management.

[Validation into Spanish of the revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire to assess patients' attitudes towards deprescribing. Research protocol]

INTRODUCTION AND OBJECTIVE

Polypharmacy has become a priority public health problem in developed countries. In response to its approach, deprescription stands out. Its success will depend largely on the attitudes and beliefs of patients towards the number of drugs they are taking and their willingness to initiate a process of deprescription. To explore these factors, researchers have developed the revised Patients' Attitudes Towards Deprescribing (rPATD) questionnaire, originally in English. The objective of this study is the validation into Spanish of rPATD questionnaire, both older adults and caregivers versions.

MATERIAL AND METHODS

A first qualitative validation phase and a second phase of analysis of its psychometric characteristics will be carried out through an observational descriptive study of validation of a measurement instrument. One hundred and twenty subjects (polymedicated older adults and caregivers) from three health centers will be selected by consecutive sampling. The questionnaire will be provided and clinical and sociodemographic data will be collected. Feasibility, reliability (through internal consistency and intraobserver reliability) and validity (apparent, construct and criterion) of the questionnaire will be evaluated.

EXPECTED RESULTS

It is expected to obtain a questionnaire that will serve as a tool for the clinician to identify patients with a favorable predisposition to deprescription and that will allow to contribute the patient's perspective to this process.

CONCLUSION

The use of the rPATD questionnaire, alone or integrated into other more complex interventions, may lead to an improvement in the quality of care for the polymedicated patients.

Quality of opioid prescribing in older adults with or without Alzheimer disease and related dementia

Background

Pain is common among individuals with Alzheimer’s disease and related dementias (ADRD), and use of opioids has been increasing over the last decade. Yet, it is unclear to what extent opioids are appropriately prescribed for patients with ADRD and whether the appropriateness of opioid prescribing differs by ADRD status. The objective of this study is to compare the quality of opioid prescribing among patients with or without ADRD who have chronic noncancer pain.

Methods

A nationally representative cohort study of Medicare beneficiaries aged 50 years or older who had chronic pain but who had no cancer, hospice, or palliative care from 2011 to 2015. Four indicators of potentially inappropriate opioid prescribing were measured in patients residing in communities (75,258 patients with and 435,870 patients without ADRD); five indicators were assessed in patients in nursing homes (NHs) (37,117 patients with and 5128 patients without ADRD). Each indicator was calculated as the proportion of eligible patients with inappropriate opioid prescribing in the year after a chronic pain diagnosis. Differences in proportions between ADRD and non-ADRD groups were estimated using a generalized linear model adjusting for covariates through inverse probability weighting.

Results

Patients with ADRD versus those without had higher concurrent use of opioids and central nervous system–active drugs (community 44.1% vs 33.3%; NH 58.8% vs 54.1%, both P < 0.001) and no opioids or scheduled pain medications for moderate or severe pain (NH 60.1% vs 52.5%, P < 0.001). The ADRD versus non-ADRD group had higher use of long-term opioids for treating neuropathic pain in communities (21.7% vs 19.5%, P = 0.003) but lower use in NHs (26.9% vs 36.0%, P < 0.001). Use of strong or high-dose opioids when naive to opioids (community 1.5% vs 2.8%; NH 2.5% vs 3.5%) and use of contraindicated opioids (community 0.08% vs 0.12%; NH 0.05% vs 0.21%) were rare for either group.

Conclusion

Potential inappropriate opioid prescribing in 2 areas of pain care was more common among patients with ADRD than among patients without ADRD in community or NH settings. Further studies aimed at understanding the factors and effects associated with opioid prescribing patterns that deviate from guidelines are warranted.

Epidemiology and associated factors of polypharmacy in older patients in primary care: a northern Italian cross-sectional study

Background

A precondition for developing strategies to reduce polypharmacy and its well-known harmful consequences is to study its epidemiology and associated factors. The objective of this study was to analyse the prevalence of polypharmacy (defined as ≥8 prescribed drugs), of potentially inappropriate medications (PIMs) and major drug-drug interactions (DDIs) among community-dwelling general practice patients aged ≥75 years and to identify characteristics being associated with polypharmacy.

Methods

This cross-sectional study is derived from baseline data (patients’ demographic/biometric characteristics, diagnoses, medication-related data, cognitive/affective status, quality of life) of a northern-Italian cluster-RCT. PIMs and DDIs were assessed using the 2012 Beers criteria and the Lexi-Interact® database. Data were analysed using descriptive methods, Wilcoxon rank-sum tests, Fisher’s exact tests and Spearman correlations.

Results

Of the eligible patients aged 75+, 13.4% were on therapy with ≥8 drugs. Forty-three general practitioners and 579 patients participated in the study. Forty five point nine percent of patients were treated with ≥1 Beers-listed drugs. The most frequent PIMs were benzodiazepines/hypnotics (19.7% of patients) and NSAIDs (6.6%). Sixty seven point five percent of patients were exposed to ≥1 major DDI, 35.2% to ≥2 major DDIs. Antithrombotic/anticoagulant medications (30.4%) and antidepressants/antipsychotics (23.1%) were the most frequently interacting drugs. Polypharmacy was significantly associated with a higher number of major DDIs (Spearman’s rho 0.33, p < 0.001) and chronic conditions (Spearman’s rho 0.20, p < 0.001), higher 5-GDS scores (thus, lower affective status) (Spearman’s rho 0.12, p = 0.003) and lower EQ-5D-5L scores (thus, lower quality of life) (Spearman’s rho − 0.14, p = 0.001). Patients’ age/sex, 6-CIT scores (cognitive status), BMI or PIM use were not correlated with the number of drugs.

Conclusions

The prevalence of polypharmacy, PIMs and major DDIs was considerable. Results indicate that physicians should particularly observe their patients with multiple conditions, reduced health and affective status, independently from other patients’ characteristics. Careful attention about indication, benefit and potential risk should be paid especially to patients on therapy with specific drug classes identified as potentially inappropriate or prone to major DDIs in older persons (e.g., benzodiazepines, NSAIDs, protonic pump inhibitors, antithrombotics/anticoagulants, antidepressants/antipsychotics).

Trial registration

The cluster-RCT on which this cross-sectional analysis is based was registered with Current Controlled Trials Ltd. (ID ISRCTN: 38449870) on 2013-09-11.

Polypharmacy in older adults: a narrative review of definitions, epidemiology and consequences

BACKGROUND

The number of older adults has been constantly growing around the globe. Consequently, multimorbidity and related polypharmacy have become an increasing problem. In the absence of an accepted agreement on the definition of polypharmacy, data on its prevalence in various studies are not easily comparable. Besides, the evidence on the potential adverse clinical outcomes related to polypharmacy is limited though polypharmacy has been linked to numerous adverse clinical outcomes. This narrative review aims to find and summarize recent publications on definitions, epidemiology and clinical consequences of polypharmacy.

METHODS

The MEDLINE database was used to identify recent publications on the definition, prevalence and clinical consequences of polypharmacy using their respective common terms and their variations. Systematic reviews and original studies published between 2015 and 2020 were included.

RESULTS

One hundred and forty-three definitions of polypharmacy and associated terms were found. Most of them are numerical definitions. Its prevalence ranges from 4% among community-dwelling older people to over 96.5% in hospitalized patients. In addition, numerous adverse clinical outcomes were associated with polypharmacy.

CONCLUSION

The term polypharmacy is imprecise, and its definition is yet subject to an ongoing debate. The clinically oriented definitions of polypharmacy found in this review such as appropriate or necessary polypharmacy are more useful and relevant. Regardless of the definition, polypharmacy is highly prevalent in older adults, particularly in nursing home residents and hospitalized patients. Approaches to increase the appropriateness of polypharmacy can improve clinical outcomes in older adults.

Guidance for appropriate use of psychotropic drugs in older people

Psychotropic drugs are widely prescribed in older people although their use is associated with important risks. In this position paper, we discuss the appropriateness of using these medications in older people in terms of different aspects such as indications, contraindications, dosing, adverse drug reactions, interactions and duration of therapy. Consequently, we discuss different strategies to increase the appropriateness of therapy while formulating some practical recommendations to keep in mind when (de)prescribing psychotropic drugs in older people.

Guideline-led prescribing to ambulatory heart failure patients in a cardiology outpatient service

Background Guidelines recommend heart failure (HF) patients be treated with multiple medications at doses proven to improve clinical outcomes. Objective To study guideline-led prescribing in an Irish outpatient HF population. Setting Cardiology Outpatient Clinic, Mercy University Hospital, Cork, Ireland. Methods Guideline-led prescribing was assessed using the Guideline Adherence Index (GAI-3), that considered the prescribing of ACE inhibitors and angiotensin receptor blockers; beta-blockers and mineralocorticoid receptor antagonists. The GAI-based target dose was calculated based on the prescription of ≥ 50% of the guideline-recommended target dose of each of the three GAI medications to HF patients with ejection fraction ≤ 40%. High-GAI was achieved by prescription of ≥ 2 GAI medicines. Potentially inappropriate prescribing was assessed using a HF-specific tool. Main outcome measure Heart failure guideline-led prescribing assessed using the GAI-3. Results A total of 127 HF patients, mean age 71.7 ± 13.1 years, were identified in the study. Seventy-one patients had ejection fraction ≤ 40%. Population mean GAI-3 was 65.8%. When contraindications to therapy are considered, the adjusted GAI-3 increased to 72.9%. The target dose GAI was 18.5%. High-GAI management was prescribed to 54 patients (76.1%). A potentially inappropriate medicine in HF was prescribed to 14 (19.7%) patients. Conclusion Most HF patients with ejection fraction ≤ 40% in this setting received optimal guideline-led prescribing however the proportion of patients achieving the target doses of these agents was suboptimal.

Establishing a primary care audit and feedback implementation laboratory: a consensus study

BACKGROUND

There is a significant variation among individual primary care providers in prescribing of potentially problematic, low-value medicines which cause avoidable patient harm. Audit and feedback is generally effective at improving prescribing. However, progress has been hindered by research waste, leading to unanswered questions about how to include audit and feedback for specific problems and circumstances. Trials of different ways of providing audit and feedback in implementation laboratories have been proposed as a way of improving population healthcare while generating robust evidence on feedback effects. However, there is limited experience in their design and delivery.

AIM

To explore priorities, feasibility, and ethical challenges of establishing a primary care prescribing audit and feedback implementation laboratory.

DESIGN AND SETTING

Two-stage Delphi consensus process involving primary care pharmacy leads, audit and feedback researchers, and patient and public.

METHOD

Participants initially scored statements relating to priorities, feasibility, and ethical considerations for an implementation laboratory. These covered current feedback practice, priority topics for feedback, usefulness of feedback in improving prescribing and different types of prescribing data, acceptability and desirability of different organization levels of randomization, options for trial consent, different methods of delivering feedback, and interest in finding out how effective different ways of presenting feedback would be. After receiving collated results, participants then scored the items again. The consensus was defined using the GRADE criteria. The results were analyzed by group and overall score.

RESULTS

Fourteen participants reached consensus for 38 out of 55 statements. Addressing antibiotic and opioid prescribing emerged as the highest priorities for action. The panel supported statements around addressing high-priority prescribing issues, taking an "opt-out" approach to practice consent if waiving consent was not permitted, and randomizing at lower rather than higher organizational levels. Participants supported patient-level prescribing data and further research evaluating most of the different feedback methods we presented them with.

CONCLUSIONS

There is a good level of support for evaluating a wide range of potential enhancements to improve the effects of feedback on prescribing. The successful design and delivery of a primary care audit and feedback implementation laboratory depend on identifying shared priorities and addressing practical and ethical considerations.

Impact of a multifaceted intervention to improve antibiotic prescribing: a pragmatic cluster-randomised controlled trial

OBJECTIVES

This study sought to assess the effectiveness and return on investment (ROI) of a multifaceted intervention aimed at improving antibiotic prescribing for acute respiratory infections in primary care.

DESIGN

Large-sized, two-arm, open-label, pragmatic, cluster-randomised controlled trial.

SETTING

All primary care physicians working for the Spanish National Health Service (NHS) in Galicia (region in north-west Spain).

PARTICIPANTS

The seven spatial clusters were distributed by unequal randomisation (3:4) of the intervention and control groups. A total of 1217 physicians (1.30 million patients) were recruited from intervention clusters and 1393 physicians (1.46 million patients) from control clusters.

INTERVENTIONS

One-hour educational outreach visits tailored to training needs identified in a previous study; an online course integrated in practice accreditation; and a clinical decision support system.

MAIN OUTCOME MEASURES

Changes in the ESAC (European Surveillance of Antimicrobial Consumption) quality indicators for outpatient antibiotic use. We used generalised linear mixed and conducted a ROI analysis to ascertain the overall cost savings.

RESULTS

Median follow-up was 19 months. The adjusted effect on overall antibiotic prescribing attributable to the intervention was - 4.2% (95% CI: - 5.3% to - 3.2%), with this being more pronounced for penicillins - 6.5 (95% CI: - 7.9% to - 5.2%) and for the ratio of consumption of broad- to narrow-spectrum penicillins, cephalosporins, and macrolides - 9.0% (95% CI: - 14.0 to - 4.1%). The cost of the intervention was €87 per physician. Direct savings per physician attributable to the reduction in antibiotic prescriptions was €311 for the NHS and €573 for patient contributions, with an ROI of €2.57 and €5.59 respectively.

CONCLUSIONS

Interventions designed on the basis of gaps in physicians' knowledge of and attitudes to misprescription can improve antibiotic prescribing and yield important direct cost savings.

Appropriateness of direct oral anticoagulant dosing in patients with atrial fibrillation according to the drug labelling and the EHRA Practical Guide

BACKGROUND

This study aimed to evaluate the prevalence of potential drug-drug interactions (DDIs) and the appropriateness of direct oral anticoagulant (DOAC) dosing according to both the Summary of Product Characteristics (SmPC) and the European Heart Rhythm Association (EHRA) Practical Guide in a 'real-world' sample of non-valvular atrial fibrillation (NVAF) patients.

METHODS AND RESULTS

Data of a cross-sectional observational study in a primary care sample of 654 long-term DOAC users were used for this sub-analysis. A total of 262 potential DDIs were identified in 220 patients (33.6%). Pharmacodynamic DDIs were present in 163 patients (24.9%) and pharmacokinetic DDIs in 82 patients (12.5%). One-third of patients (33.8%) received reduced DOAC dose. According to the dosing recommendations in the SmPC, 81.7% of DOACs were dosed appropriately. According to the EHRA recommendations, 76.6% of DOACs were dosed appropriately. Dosing recommendations were consistent for 90.7% of patients, with both the SmPC and EHRA Practical Guide considering DOACs dosed appropriately in 74.5% of patients, overdosed in 7.8%, underdosed in 7.6% and contraindicated in 0.8%. However, for the remaining 9.3% dosing recommendations differed between SmPC and EHRA.

CONCLUSIONS

This 'real-world' analysis of DOAC dosing demonstrated that in about one-third of NVAF patients potential DDIs were present. In 18.3% and 23.4% of patients, DOACs were dosed inappropriately according to the SmPC and EHRA Practical Guide respectively. In almost 10% of the study population dosing advice was inconsistent between both references. More research is needed to ensure appropriate DOAC dosing in this 'grey zone' population.

Potentially inappropriate prescribing in older hospitalized Dutch patients according to the STOPP/START criteria v2: a longitudinal study

Purpose

To investigate prevalence, independent associations, and variation over time of potentially inappropriate prescriptions in a population of older hospitalized patients.

Methods

A longitudinal study using a large dataset of hospital admissions of older patients (≥ 70 years) based on an electronic health records cohort including data from 2015 to 2019. Potentially inappropriate medication (PIM) and potential prescribing omission (PPO) prevalence during hospital stay were identified based on the Dutch STOPP/START criteria v2. Univariate and multivariate logistic regression were used for analyzing associations and trends over time.

Results

The data included 16,687 admissions. Of all admissions, 56% had ≥ 1 PIM and 58% had ≥ 1 PPO. Gender, age, number of medications, number of diagnoses, Charlson score, and length of stay were independently associated with both PIMs and PPOs. Additionally, number of departments and number of prescribing specialties were independently associated with PIMs. Over the years, the PIM prevalence did not change (OR = 1.00, p = .95), whereas PPO prevalence increased (OR = 1.08, p < .001). However, when corrected for changes in patient characteristics such as number of diagnoses, the PIM (aOR = 0.91, p < .001) and PPO prevalence (aOR = 0.94, p < .001) decreased over the years.

Conclusion

We found potentially inappropriate prescriptions in the majority of admissions of older patients. Prescribing relatively improved over time when considering complexity of the admissions. Nevertheless, the high prevalence shows a clear need to better address this issue in clinical practice. Studies seeking effective (re)prescribing interventions are warranted.

Epidemiological Study Assessing the Overuse of Proton Pump Inhibitors in Lebanese Population

BACKGROUND Proton pump inhibitors (PPIs) are the most potent gastric agents for most acid-related disorders. Their effectiveness has led to their overutilization, leading to potential risks on patients and significant economic implications. The aim of this study was to determine the frequency of PPI overuse in Lebanon. Hence, the economic impact of this overutilization, if proven to be present, can be inferred. METHODS An epidemiological descriptive cross-sectional study was conducted in pharmacies all around Lebanese governorates over a 1-year period, using questionnaires handed out to 1000 participants coming to buy PPIs. Subjects taking PPIs for inappropriate indications or in inappropriate dosages or durations were considered abusing PPIs. PPIs are indicated for multiple gastric disorders and for prophylaxis of gastrointestinal injury when taking gastro-toxic medications. RESULTS 71.4% of subjects were overusing PPIs. Approximately 25 million US dollars were being wasted annually. Three categories of overuse were inferred (indication, dosage, and duration). Gastro protection was the most common reason for taking PPIs. Demographic variables and doctors' prescriptions did not influence PPI overuse. CONCLUSION PPIs are massively overused in Lebanon, leading to a huge burden on the health care system. Adhering to evidence-based guidelines and educational programs is highly recommended to enhance the quality and efficiency of prescriptions.

Potentially Inappropriate Prescriptions in Heart Failure with Reduced Ejection Fraction (PIP-HFrEF)

Heart failure (HF) is a chronic debilitating and potentially life-threatening condition. Heart Failure patients are usually at high risk of polypharmacy and consequently, potentially inappropriate prescribing leading to poor clinical outcomes. Based on the published literature, a comprehensive HF-specific prescribing review tool is compiled to avoid medications that may cause HF or harm HF patients and to optimize the prescribing practice of HF guideline-directed medical therapies. Recommendations are made in line with the last versions of ESC guidelines, ESC position papers, scientific evidence, and experts' opinions.

A survey on what pharmacists and physicians caring for nursing home residents expect of user-friendly lists of potentially inappropriate prescribing (PIP lists)

INTRODUCTION

Potentially inappropriate prescribing (PIP, including potentially inappropriate medication, PIM) is frequent. In research and practice, the use of PIP lists could optimize a patient's medication. However, they are barely used, possibly because of their limited user-friendliness. This study aimed at evaluating the opinions of pharmacists and physicians caring for nursing home residents on user-friendliness as well as knowledge and current use of PIP lists.

METHODS

Semi-structured telephone interviews and paper-based surveys were conducted with physicians and pharmacists who care for nursing home residents. Descriptive analysis and Fisher's exact test were performed.

RESULTS

A total of 30 practitioners participated in the survey, eight of whom were interviewed by phone. 43 % (13/30) of the participants had already heard of PIP lists, and 46 % (6/13) of them made use of a PIP list. Less experienced professionals had more often heard of PIP lists than more experienced ones. The most important aspects of user-friendliness were: time required to use the list, electronic availability, clear structure and provision of reasons why a medication is potentially inappropriate. Physicians preferred a PIP list adapted to the Swiss drug market more often than pharmacists.

DISCUSSION

Knowledge and current use of PIP lists are limited, which is partially consistent with the results of other studies. Participants with less professional experience have heard of PIP lists more frequently, opinions on user-friendliness differ between professions, and preferences seem to be, overall, highly individual.

CONCLUSION

In order for PIP lists to be used more frequently, the aspects of user-friendliness should be taken into account. Personalizable PIP lists could be an interesting development.

Impact of a pharmacist and geriatrician medication review on drug-related problems in older outpatients with cancer

OBJECTIVES

Older patients with cancer have increased risk for comorbidity, polypharmacy (PP) and drug related problems (DRP). The aim of this study was to assess the effect of a clinical pharmacist and geriatrician medication review (MR) among older outpatients with cancer to optimize management of comorbidities during comprehensive geriatric assessment (CGA).

MATERIAL AND METHODS

We conducted a single-center prospective study among older outpatients with cancer (≥75 years). A pharmacist consultation was added into CGA process. The clinical pharmacist detected and assessed PP and DRP such as potentially inappropriate medications (PIM) according to the Laroche French list and STOPP criteria, START criteria and adverse drug events (ADE) risk. After a multidisciplinary MR, the proposals for prescription modification were sent to general practitioners (GPs).

RESULTS

Fifty-one consenting patients were recruited between May 2016 and March 2017, with a median age of 83 years. Prevalence of PP was 80.4%. 165 DRP were detected among 86% patients (median number of DRP = 3.0): 19.4% were misuse, 43.6% underuse, and 37.0% overuse. A significant decrease was observed in prevalence of PIM use (Laroche: 31.4% versus 5.9%, p = 0.002), START criteria (66.7% to 5.9%; P < 0.001) and ADE score (4.0 before MR versus 2.0 after, p = 0.023). A trend was observed for a lower number of medications (10.0 versus 8.0, p = 0.092) and on STOPP criteria prevalence (56.9% versus 31.4%, p = 0.12).

CONCLUSION

A clinical pharmacist and a geriatrician MR is effective to detect and reduce DRP in older outpatients with cancer.

FORTA(Fit-fOR-The-Aged)-based medication optimization: retrospective analysis of experiences from an unconventional outpatient service

Aim

To map prescription considerations concerning older community dwelling subjects emerging in a special gerontopharmacology hospital-based consultation.

Findings

Almost 10 recommendations had to be issued per patient: drugs to be stopped, added or replaced, dosing, frequency and time of intake were optimized. Applying the Fit-fOR-The-Aged (FORTA) tool resulted in a significant improvement of under- and overtreatment errors, and the sum of errors, the FORTA score.

Message

A medication review service aided by the FORTA tool detects a large number of medication errors in older outpatients and should be established in other places as well.

Purpose

To address potentially harmful polypharmacy in multimorbid older patients. Secondary to assess FORTA (Fit-fOR-The-Aged) utility in ambulatory patients.

Methods

Consecutive patients attending a novel ambulatory service for gerontopharmacology were included in this retrospective analysis. Baseline data, diagnoses, previous drug treatment and recommended changes in medication were analysed and the change of the FORTA score (sum of over- and undertreatment errors) calculated.

Results

The analysis of 182 cases revealed a high number of recommended medication alterations per case (9.81; 95% CI 9.13–10.50). The FORTA score was significantly reduced from 4.24 ± 2.30 to 0.80 ± 1.08 (P < 0.00001), as were under- and overtreatment errors if analysed separately.

Conclusions

The large number of recommendations given in this special outpatient service points to a profound unmet medical need for improving medications in older patients. The FORTA approach was found to be useful to reduce both over- and undertreatment in multimorbid older patients.

Potentially inappropriate prescribing to older patients receiving multidose drug dispensing

Background

Multidose drug dispensing (MDD) is an adherence aid that provides patients with machine-dispensed medicines in disposable unit bags, usually for a 14 day period. Previous studies have suggested that the quality of prescribing, with time, is lower for MDD users, compared to patients receiving prescriptions dispensed as usual. This study aimed to examine the quality of prescribing to Norwegian elderly home care service patients receiving MDD.

Methods

A cross-sectional study comprising 45,593 MDD patients aged ≥70 years was performed. The proportion of potentially inappropriate medications (PIMs) was assessed using the Norwegian General Practice Criteria, and drug-drug interactions (DDI) were investigated using the Norwegian Medicines Agency database.

Results

On average, patients were prescribed 10.6 drugs (SD = 5.0), of which 6.1 were dispensed via MDD. Men used on average fewer drugs than women (10.7 vs 11.1), Twenty-seven percent of patients used at least one PIM. Concomitant use of three or more psychotropic drugs (10.8%), and prescribing of diazepam (6.4%) was the most commonly identified inappropriate prescribing. DDIs affected 59% of the patients, however, only 2.7% had serious interactions. Women were more frequently exposed to both PIMs and DDIs than men, with an odds ratio of 1.50 (95% CI: 1.43–1.58) and 1.43 (95% CI: 1.37–1.50), respectively.

Conclusions

Polypharmacy is common in elderly Norwegian patients using MDD. About one-fourth of the patients were exposed to PIMs, and over half were exposed to DDI.

The JAPAN-FORTA (Fit fOR The Aged) list: Consensus validation of a clinical tool to improve drug therapy in older adults

PURPOSE

Multimorbidity and subsequent polypharmacy are highly prevalent in older people. To improve inappropriate drug treatment, listing approaches such as the Beers or FORTA lists have been developed. Latter is the only clinically validated drug list issuing both positive (FORTA labels A, B) and negative (FORTA labels C, D) recommendations. Several country-specific FORTA lists have been developed to acknowledge national prescription habits, drug availabilities, and expert opinions. Here, this approach was applied to Japan.

METHODS

13 Japanese experts in geriatric pharmacotherapy participated as raters in a 2-step Delphi consensus validation of the FORTA list. The proposal of FORTA labels was based on the EURO-FORTA List and raters were asked to add, delete or re-evaluate medications, add relevant diagnoses and comments.

RESULTS

The final JAPAN-FORTA list contains 210 items aligned to 24 main indication groups. 15 items were added to the proposal and the 71 items either not used/approved in Japan or not evaluated by any rater (oncological drugs) were removed. Excluding latter, the JAPAN-FORTA list differs from the EURO-FORTA list by 23 %. Removals mainly concerned psychotropic drugs. A maximum of one label was changed per indication. The majority (96.9 percent) of the proposed FORTA labels were confirmed, only 6 labels had to be changed.

CONCLUSION

The new JAPAN-FORTA list addresses the appropriateness of drug treatment in older people in Japan. This unique listing approach issuing both positive and negative medication recommendations has been shown to improve of drug therapy in older adults and its country-specific version is now available for Japan.

Inappropriate use of carbapenems in an internal medicine ward: Impact of a carbapenem-focused antimicrobial stewardship program

PURPOSE

Carbapenem consumption is a major driver for selection and spread of carbapenem-resistant Enterobacterales (CRE). We assessed the impact of a carbapenem-focused multimodal antimicrobial stewardship program (ASP) in the internal medicine unit of a medium-size acute-care hospital.

METHODS

We compared the percentage of inappropriate carbapenem prescriptions and the proportion of carbapenem treated patients registered in a 12-month pre-intervention and in a 24-month post-intervention period by using an interrupted time series analysis. The consumption of carbapenems, expressed in defined daily doses (DDD), was also assessed. As a secondary objective, the incidence of infections by carbapenem-resistant Klebsiella pneumoniae (CRKP) and the percentage of CRKP invasive isolates in the same time periods were compared.

RESULTS

After the ASP intervention, the mean monthly percentage of inappropriate carbapenem prescriptions dropped from 59% to 25%, and the mean monthly proportion of carbapenem treated patients decreased from 3% to 1%. The interrupted time series analysis confirmed a significant decrease in the percentage of inappropriate carbapenem prescriptions (-41.6%, p = 0.0262) and in the proportion of carbapenem treated patients (-2.1%, p < 0.0001). Carbapenem consumption decreased from 5.2 to 1.6 DDD x 100 patient-days. The incidence of CRKP infections remained unchanged (29.1 × 100,000 patient-days vs 28.9 × 100,000 patient-days, p = 0.9864) and the percentage of CRKP invasive isolates decreased, though not significantly, from 36.4% to 13.3% (p = 0.3478).

CONCLUSIONS

The implementation of a carbapenem-focused ASP was effective at limiting the inappropriate use of carbapenems and was associated with a significant decrease in carbapenem consumption. Such effects were sustained during a 24-month post-intervention period.

Integrated health intervention on polypharmacy and inappropriate prescribing in elderly people with multimorbidity: Results at the end of the intervention and at 6 months after the intervention

BACKGROUND AND OBJECTIVE

To analyse the impact of an integrated health intervention focused on polypharmacy and inappropriate prescribing (IP) in elderly people with multimorbidity.

MATERIAL AND METHODS

Patients were referred for assessment and intervention from primary care or hospital to an interdisciplinary team composed of primary and hospital medical staff and nurses. Pharmacological assessment was centred on polypharmacy and IP using the STOPP/START criteria. Changes in polypharmacy and in IP were analysed at the end of the intervention and at 6 months.

RESULTS

One hundred consecutive patients (mean (SD) age 81.5(8.0) years, 54(54%) male) were analysed. Mean prescribed medicines at baseline was > 10. There were no significant changes at the end of the intervention and at 6 months. The proportion of patients with two or more STOPP criteria reduced from 37% at the beginning of the intervention to 18% at the end (p< .001), and the proportion of those with START criteria from 13% to 6% (p = .004). These differences persisted at 6 months. The number of STOPP and START criteria before the intervention was associated with a decrease in the STOPP and START criteria at the end of the intervention and at 6 months. A reduction in polypharmacy (p= .041) and in falls (p= .034) was observed at 6 months in those with a decrease in the STOPP criteria at the end of the intervention.

CONCLUSIONS

An integrated health intervention centred on polypharmacy and IP in elderly people improves inappropriate prescribing that persists beyond the intervention.

Quality use of medicines in patients with chronic kidney disease

BACKGROUND

Chronic kidney disease (CKD) affects drug elimination and patients with CKD require appropriate adjustment of renally cleared medications to ensure safe and effective pharmacotherapy. The main objective of this study was to determine the extent of potentially inappropriate prescribing (PIP; defined as the use of a contraindicated medication or inappropriately high dose according to the kidney function) of renally-cleared medications commonly prescribed in Australian primary care, based on two measures of kidney function. A secondary aim was to assess agreement between the two measures.

METHODS

Retrospective analysis of routinely collected de-identified Australian general practice patient data (NPS MedicineWise MedicineInsight from January 1, 2013, to June 1, 2016; collected from 329 general practices). All adults (aged ≥18 years) with CKD presenting to general practices across Australia were included in the analysis. Patients were considered to have CKD if they had two or more estimated glomerular filtration rate (eGFR) recorded values < 60 mL/min/1.73m², and/or two urinary albumin/creatinine ratios ≥3.5 mg/mmol in females (≥2.5 mg/mmol in males) at least 90 days apart. PIP was assessed for 49 commonly prescribed medications using the Cockcroft-Gault (CG) equation/eGFR as per the instructions in the Australian Medicines Handbook.

RESULTS

A total of 48,731 patients met the Kidney Health Australia (KHA) definition for CKD and had prescriptions recorded within 90 days of measuring serum creatinine (SCr)/estimated glomerular filtration rate (eGFR). Overall, 28,729 patients were prescribed one or more of the 49 medications of interest. Approximately 35% (n = 9926) of these patients had at least one PIP based on either the Cockcroft-Gault (CG) equation or eGFR (CKD-EPI; CKD-Epidemiology Collaboration Equation). There was good agreement between CG and eGFR while determining the appropriateness of medications, with approximately 97% of the medications classified as appropriate by eGFR also being considered appropriate by the CG equation.

CONCLUSION

This study highlights that PIP commonly occurs in primary care patients with CKD and the need for further research to understand why and how this can be minimised. The findings also show that the eGFR provides clinicians a potential alternative to the CG formula when estimating kidney function to guide drug appropriateness and dosing.

Effects of de-implementation strategies aimed at reducing low-value nursing procedures: a systematic review and meta-analysis

Background

In the last decade, there is an increasing focus on detecting and compiling lists of low-value nursing procedures. However, less is known about effective de-implementation strategies for these procedures. Therefore, the aim of this systematic review was to summarize the evidence of effective strategies to de-implement low-value nursing procedures.

Methods

PubMed, Embase, Emcare, CINAHL, PsycINFO, Cochrane Central Register of Controlled Trials, Web of Science, and Google Scholar were searched till January 2020. Additionally, reference lists and citations of the included studies were searched. Studies were included that described de-implementation of low-value nursing procedures, i.e., procedures, test, or drug orders by nurses or nurse practitioners. PRISMA guideline was followed, and the ‘Cochrane Effective Practice and Organisation of Care’ (EPOC) taxonomy was used to categorize de-implementation strategies. A meta-analysis was performed for the volume of low-value nursing procedures in controlled studies, and Mantel–Haenszel risk ratios (95% CI) were calculated using a random effects model.

Results

Twenty-seven studies were included in this review. Studies used a (cluster) randomized design (n = 10), controlled before-after design (n = 5), and an uncontrolled before-after design (n = 12). Low-value nursing procedures performed by nurses and/or nurse specialists that were found in this study were restraint use (n = 20), inappropriate antibiotic prescribing (n = 3), indwelling or unnecessary urinary catheters use (n = 2), ordering unnecessary liver function tests (n = 1), and unnecessary antipsychotic prescribing (n = 1). Fourteen studies showed a significant reduction in low-value nursing procedures. Thirteen of these 14 studies included an educational component within their de-implementation strategy. Twelve controlled studies were included in the meta-analysis. Subgroup analyses for study design showed no statistically significant subgroup effect for the volume of low-value nursing procedures (p = 0.20).

Conclusions

The majority of the studies with a positive significant effect used a de-implementation strategy with an educational component. Unfortunately, no conclusions can be drawn about which strategy is most effective for reducing low-value nursing care due to a high level of heterogeneity and a lack of studies. We recommend that future studies better report the effects of de-implementation strategies and perform a process evaluation to determine to which extent the strategy has been used.

Trial registration

The review is registered in Prospero (CRD42018105100).

Deprescribing opportunities for elderly inpatients in an academic, safety-net health system

BACKGROUND

Deprescribing is one way to reduce inappropriate polypharmacy in older adult patients. Although algorithms have been published to guide practitioners in deprescribing, it is still unknown how applicable these algorithms are to the general older adult population.

OBJECTIVES

The primary objective was to assess the applicability of published deprescribing protocols in hospitalized older adult patients.

METHODS

This retrospective study included patients aged 65 years or greater who were discharged from an internal medicine team between January 1, 2017 and June 30, 2017. Along with age and admission to internal medicine wards, other eligibility criteria were extracted from published deprescribing protocols. The primary endpoint was the proportion of patients eligible for deprescribing based on published algorithms. Secondary endpoints included the proportion of patients receiving medications which were included in an algorithm, proportion of patients using medications included in the algorithms who were eligible for deprescribing, and proportion of patients with medications deprescribed during the hospital stay.

RESULTS

Two hundred sixty-seven patients were included and 124 (46.4%) used a medication with a published deprescribing algorithm. Thirty-four percent of all patients and 74% (92/124) of patients prescribed medications included in algorithms were eligible for deprescribing. Seven percent (6/92) of patients eligible for deprescribing had medications deprescribed during the hospital stay.

CONCLUSION

The application of deprescribing algorithms in hospitalized older adults identified a significant opportunity to initiate deprescribing practices.

Prescribing for geriatrics in Tehran; is it appropriate and rational?

Background: The world’s population is growing older. Inappropriate and irrational use of drugs in the elderly is a considerable health concern due to consequences such as increased morbidity and adverse drug events. This study aimed to evaluate the rationality of prescribing and determining the extent of inappropriate prescribing in a sample of geriatric patients in Tehran.

Methods: This cross sectional study was performed on 1512 prescriptions of patients aged ≥ 65 years from 5 pharmacies affiliated to Tehran University of Medical Sciences in 2014. Prescription of potentially inappropriate medications (PIMs) was investigated using the Beers Criteria along with WHO prescribing indices. Date were analyzed using SPSS software, and significance level was set at less than 0.05.

Results: Mean (SD) age of patients was 73.9(6.7) years. A total of 472 (31.2%) patients received at least 1 PIM. Benzodiazepines were the most frequent drug class and general practitioners (GPs) were the most frequent prescriber of PIMs. The highest and the lowest percentage of prescriptions containing brand-names were prescribed by subspecialists (62.5%) and GPs (42.2%), respectively. Antibiotics and injectable medications were prescribed for 26.8% and 28.5% of patients by GPs. Mean (SD) number of drugs per prescription was 3.57 (1.92). Prescriptions containing systemic antibiotics and PIMs had significantly higher mean number of drugs compared to those without these items (both P < 0.001).

Conclusion: There is a need for interventions to improve the quality of prescribing for elderly patients, especially by GPs. Also, there are still some problems in rational use of drugs based on prescribing indices, especially, prescribing brand-names and injectable medications.

Changes in anticoagulant prescription in Dutch patients with recent-onset atrial fibrillation: observations from the GARFIELD-AF registry

Background

For the improvement of AF care, it is important to gain insight into current anticoagulation prescription practices and guideline adherence. This report focuses on the largest Dutch subset of AF-patients, derived from the GARFIELD-AF registry.

Methods

Across 35 countries worldwide, patients with newly diagnosed ‘non-valvular’ atrial fibrillation (AF) with at least one additional risk factor for stroke were included. Dutch patients were enrolled in five, independent, consecutive cohorts from 2010 until 2016.

Results

In the Netherlands, 1189 AF-patients were enrolled. The prescription of non-vitamin K antagonist oral anticoagulants (NOAC) has increased sharply, and as per 2016, more patients were initiated on NOACs instead of vitamin K antagonists (VKA). In patients with a class I recommendation for anticoagulation, only 7.5% compared to 30.0% globally received no anticoagulation. Reasons for withholding anticoagulation in these patients were unfortunately often unclear.

Conclusions

The data from the GARFIELD-AF registry shows the rapidly changing anticoagulation preference of Dutch physicians in newly diagnosed AF. Adherence to European AF guidelines in terms of anticoagulant regimen would appear to be appropriate. In absence of structured follow up of AF patients on NOAC, the impact of these rapid practice changes in anticoagulation prescription in the Netherlands remains to be established.

Intervention protocol: OPtimising thERapy to prevent avoidable hospital Admission in the Multi-morbid elderly (OPERAM): a structured medication review with support of a computerised decision support system

BACKGROUND

Several approaches to medication optimisation by identifying drug-related problems in older people have been described. Although some interventions have shown reductions in drug-related problems (DRPs), evidence supporting the effectiveness of medication reviews on clinical and economic outcomes is lacking. Application of the STOPP/START (version 2) explicit screening tool for inappropriate prescribing has decreased inappropriate prescribing and significantly reduced adverse drug reactions (ADRs) and associated healthcare costs in older patients with multi-morbidity and polypharmacy. Therefore, application of STOPP/START criteria during a medication review is likely to be beneficial. Incorporation of explicit screening tools into clinical decision support systems (CDSS) has gained traction as a means to improve both quality and efficiency in the rather time-consuming medication review process. Although CDSS can generate more potential inappropriate medication recommendations, some of these have been shown to be less clinically relevant, resulting in alert fatigue. Moreover, explicit tools such as STOPP/START do not cover all relevant DRPs on an individual patient level. The OPERAM study aims to assess the impact of a structured drug review on the quality of pharmacotherapy in older people with multi-morbidity and polypharmacy. The aim of this paper is to describe the structured, multi-component intervention of the OPERAM trial and compare it with the approach in the comparator arm.

METHOD

This paper describes a multi-component intervention, integrating interventions that have demonstrated effectiveness in defining DRPs. The intervention involves a structured history-taking of medication (SHiM), a medication review according to the systemic tool to reduce inappropriate prescribing (STRIP) method, assisted by a clinical decision support system (STRIP Assistant, STRIPA) with integrated STOPP/START criteria (version 2), followed by shared decision-making with both patient and attending physician. The developed method integrates patient input, patient data, involvement from other healthcare professionals and CDSS-assistance into one structured intervention.

DISCUSSION

The clinical and economical effectiveness of this experimental intervention will be evaluated in a cohort of hospitalised, older patients with multi-morbidity and polypharmacy in the multicentre, randomized controlled OPERAM trial (OPtimising thERapy to prevent Avoidable hospital admissions in the Multi-morbid elderly), which will be completed in the last quarter of 2019.

The appropriateness of antimicrobial use in the outpatient clinics of three hospitals in the Netherlands

OBJECTIVES

Antimicrobial Stewardship Programs commonly have an in-hospital focus. Little is known about the quality of antimicrobial use in hospital outpatient clinics. We investigated the extent and appropriateness of antimicrobial prescriptions in the outpatient clinics of three hospitals.

METHODS

From June 2018 to January 2019, we performed ten point prevalence surveys in outpatient clinics of one university hospital and two large teaching hospitals. All prophylactic and therapeutic prescriptions were retrieved from the electronic medical records. Appropriateness was defined as being in accordance with guidelines. Furthermore, we investigated the extent to which the dose was adjusted to renal function and documentation of an antibiotic plan in the case notes.

RESULTS

We retrieved 720 prescriptions for antimicrobial drugs, of which 173 prescriptions (24%) were prophylactic. A guideline was present for 95% of prescriptions, of which the guideline non-adherence rate was 25.6% (n = 42/164) for prophylaxis and 43.1% (n = 224/520) for therapy. Of all inappropriate prescriptions (n = 266), inappropriate prescriptions for skin and soft tissue infections (n = 60/226) and amoxicillin-clavulanic acid (n = 67/266) made up the largest proportion. In only 13 of 138 patients with impaired or unknown renal function the dosage regimen was adjusted. Amoxicillin-clavulanic acid was the drug for which most often renal function was not taken into account. In 94.6% of prescriptions the antibiotic plan was documented.

CONCLUSIONS

In hospital outpatient clinics, a substantial part of therapeutics were inappropriately prescribed. Amoxicillin-clavulanic acid was the most inappropriately prescribed drug, due to non-adherence to the guidelines and because dose adjustment to renal function was often not considered.

Polypharmacy in older adults: the role of the multidisciplinary team

Patients over the age 65 are a quickly expanding segment of the US population and represent a large percentage of patients requiring inpatient care. Older adults are more likely to experience polypharmacy and adverse drug effects. This review explains the risks of polypharmacy and potentially inappropriate medications in the elderly. Specific classes of medications frequently used in older adults in acute care settings are examined, including anticholinergic, sedative hypnotics, and antipsychotic medications. We discuss strategies aimed at addressing polypharmacy in this population including a drug regimen review (which is distinct from medication reconciliation), screening tools, pharmacist-led interventions, and computer-based strategies in the context of current literature and research findings. We provide a summary of general guidelines that may be helpful for geriatricians and hospitalists in improving patient care and clinical outcomes.

A scoping review of the use and impact of telehealth medication reviews

BACKGROUND

Telehealth has been proposed as a mechanism to overcome the practical difficulties associated with conducting timely and efficient medication reviews particularly in rural and remote settings.

OBJECTIVE

The aim was to examine the literature on the use and impact of telehealth-facilitated medication reviews.

METHODS

A scoping review of the literature was conducted. Articles that reported medication reviews performed by telehealth were identified by searching the Pubmed, Embase, Cochrane Library and CINAHL databases to January 2019 and screened using predefined inclusion criteria. Data were extracted from included articles and synthesised narratively. Findings are reported using the PRISMA-ScR guidelines.

RESULTS

Twenty-nine studies, including 15 descriptive and 14 quasi-experimental studies, met the inclusion criteria. Twenty studies were reports of the implementation and/or evaluation of a service and others were proof of concept, feasibility or pilot studies. Telehealth medication reviews, conducted as standalone interventions or as a part of team-based care, included medication order reviews, medication management, antimicrobial stewardship programs and geriatric services and were delivered to patients in outpatient (n = 15) or hospital (n = 12) settings, with one study conducted in residential care and one study across settings. Outcomes reported included process evaluation (n = 23), medication use (n = 8), costs (n = 6), clinical outcomes (n = 5), and healthcare use (n = 1). Positive impact was observed on clinical outcomes (e.g. reduction in haemoglobin A_1c), medication use (e.g. reduction in antimicrobial medications) and costs (e.g. savings due to travel avoided). Good overall satisfaction with the interventions was seen in all studies that reported patient satisfaction.

CONCLUSIONS

The current evidence suggests that telehealth medication review may be a feasible model for delivering these services and potentially can save costs and improve care. However, the level of evidence may not be sufficient to reliably inform practice and policy on telehealth-facilitated medication-reviews.

Overlapping prescriptions of opioids, benzodiazepines, and carisoprodol: "Holy Trinity" prescribing in the state of Florida

BACKGROUND

High-risk combinations of controlled medications, such as those involving opioid analgesics, are under increased scrutiny because of their contribution to the opioid epidemic in the United States. Responsible prescribing guidelines indicate that the triple drug combination--opioids, benzodiazepines and skeletal muscle relaxants, especially carisoprodol--should not be concurrently prescribed.

METHODS

This pharmacoepidemiologic study was designed to primarily examine the characteristics of patients receiving this triple combination compared to the group receiving only opioids and benzodiazepines.

RESULTS

Results show that, while the number of exposed patients has declined since 2012, approximately 17,000 Floridians were prescribed this combination in 2017 alone. Demographically, recipients of these prescriptions were younger, more likely to be female, and geographically-localized. Furthermore, these patients were more frequently associated with a prescriber in the top 1% of opioid and/or benzodiazepine prescribing, have more multiple provider episodes ("doctor shopping"), and receive higher mean daily opioid dosages.

CONCLUSIONS

These findings raise important questions as to how frequently prescribers are checking prescription drug monitoring programs, following US Centers for Disease Control and Prevention opioid prescribing guidelines, and/or handling the clinical challenges associated with pharmaceutical management of patients with complex, painful health conditions.

[Strategies to improve the quality of care in the chronic patient on multiple medications]

OBJECTIVE

To carry out an evaluation of the impact on the number of patients in the risk situation due to safety problems with the medications after compliance with a program to improve the quality of care of the chronic patient on multiple medications in the Health Area of Santiago de Compostela.

METHOD

The intervention program consisted of the design of a computer tool that would allow the detection and stratification of the risk of patients with potential safety problems with medications. The program included sessions and pop-ups on the quality of the prescription and the systematic periodic communication of the results on the use of the prescriptions to the doctors and pharmacists of Primary Care. A one-year time horizon was considered.

RESULTS

In January 2018, there were 9,874 patients at risk due to potential safety problems related to medicines in the Health Area of Santiago de Compostela. At the end of December 2018, the patients at risk had fallen to 5,797 patients (41.2% reduction; P<.05).

CONCLUSIONS

The design of computer tools that allow the use of the information available from the electronic prescription using standardised protocols, along with the team work of hospital pharmacists and primary care pharmacists, the collaboration between physicians, nurses and pharmacists, as well as the design of information adapted to the computer equipment and the stratification of the risk have all been actions with very positive results in the decrease in exposure of chronic patients to risk situations related to medications.

Prescription of Systemic Steroids for Acute Respiratory Infections in Korean Outpatient Settings: Overall Patterns and Effects of the Prescription Appropriateness Evaluation Policy

OBJECTIVES

The objective of this study was to identify individual and institutional factors associated with the prescription of systemic steroids in patients with acute respiratory infections and to investigate the role of a policy measure aimed to reduce inappropriate prescriptions.

METHODS

We used data from the National Health Insurance Service-National Sample Cohort from 2006 to 2015 and focused on episodes of acute respiratory infection. Descriptive analysis and multiple logistic regression analysis were performed to identify individual-level and institution-level factors associated with the prescription of systemic steroids. In addition, steroid prescription rates were compared with antibiotic prescription rates to assess their serial trends in relation to Health Insurance Review and Assessment Service (HIRA) Prescription Appropriateness Evaluation policy.

RESULTS

Among a total of 9 460 552 episodes of respiratory infection, the steroid prescription rate was 6.8%. Defined daily doses/1000 persons/d of steroid increased gradually until 2009, but rose sharply since 2010. The steroid prescription rate was higher among ear, nose and throat specialties (13.0%) than other specialties, and in hospitals (8.0%) than in tertiary hospitals (3.0%) and other types of institutions. Following a prolonged reduction in the steroid prescription rate, this rate increased since the HIRA Prescription Appropriateness Evaluation dropped steroids from its list of evaluation items in 2009. Such a trend reversal was not observed for the prescription rate of antibiotics, which continue to be on the HIRA Prescription Appropriateness Evaluation list.

CONCLUSIONS

Specialty and type of institution are important correlates of steroid prescriptions in cases of acute respiratory infection. Steroid prescriptions can also be influenced by policy measures, such as the HIRA Prescription Appropriateness Evaluation policy.

Cardiac Rehabilitation to Optimize Medication Regimens in Heart Failure

Cardiac rehabilitation (CR) is an inherently patient-centered program that provides holistic care to adults with cardiovascular conditions to promote lifelong health and fitness, facilitate self-care and self-efficacy, and improve clinical outcomes. CR offers an excellent platform for patient-centered optimization of medication regimens for older adults with heart failure through its potential to address several aspects of care that have historically served as major challenges to clinicians-diuretic management, the use of guideline-directed medical therapy, review and reconciliation of noncardiovascular medications, and optimization of medication adherence. In this review, these challenges are described and strategies offered for leveraging CR toward addressing them.

Patients' clinical information requirements to apply the STOPP/START criteria

Background The STOPP/START criteria are an explicit tool to detect potentially inappropriate medications (PIMs). Patient clinical information may not be available in all settings. Objective To identify patient clinical information needed to apply the STOPP/START criteria. Setting: Four nursing homes in Portugal. Methods First, a theoretical analysis was performed to identify the patient information required to apply the STOPP/START criteria (v2), according to the following categories: patients' current medication, medication history (previous medication and duration), medical records (current and past medical conditions), and laboratory test results. A verification of the information requirements was conducted through a cross-sectional study on a nursing home population with patients over 65 years old. Patients' medical records were appraised to extract only demographic data and current medication profiles. Main outcome measure Information requirements of STOPP/START. Results For only 29 of the 81 STOPP criteria and 1 of the 34 START criteria, a judgement could be made with only the information in the patient's medication profile. 52 STOPP and 33 START criteria require additional information, (i.e. duration of therapy, previous medication, current and past medical conditions, and laboratory data). The 208 evaluated persons (87 years; 68.75% female) used 1770 medications, with 989 (55.9%) potentially involved in 1629 STOPP criteria. Sufficient information to judge STOPP criteria was available for only 529 (32.5%) potential STOPP criteria situations, with a positive identification of a STOPP PIM in 397 instances (75.0%). Conclusions Although STOPP/START criteria can be considered a high-level tool to identify PIMs, their use may be compromised in scenarios where access to patients' clinical information is limited.

Antibiotics prescription and guidelines adherence in elderly: impact of the comorbidities

Background

Although the interest of antibiotics is well known, antibiotics prescription is associated with side effect, especially in patients with multiples comorbidities. One way to reduce the incidence of side effects is to respect antibiotics prescriptions guidelines. Our objective was to investigated the factors associated with guidelines adherence in elderly patients with multiples comorbidities.

Methods

From October 2015 to December 2016, antibiotics prescription and guidelines adherence were analyzed in two post-acute care and rehabilitation services of a 2600-bed, university-affiliated center.

Results

One hundred and twenty-eight patients were included, fifty-nine (46%) patients had antibiotics prescription according to guidelines. In Multivariable logistic regression analysis, prescription of 2 antibiotics or more (OR = 0.168, 95% IC = 0.037–0.758, p < 0.05), 85 years of age and more (OR = 0.375, 95% IC = 0.151–0.931, p < 0.05) and the Charlson comorbidity index score (OR = 0.750, 95% IC = 0.572–0.984, p < 0.05) were negatively associated with antibiotics prescriptions according to guidelines.

Conclusions

High comorbidity in the elderly was negatively associated with the guidelines adherence of antibiotiсs prescriptions. These criteria should be considered to optimize antibiotics prescriptions in elderly patients.

High oral corticosteroid exposure and overuse of short-acting beta-2-agonists were associated with insufficient prescribing of controller medication: a nationwide electronic prescribing and dispensing database analysis

Background

Recurrent use of oral corticosteroids (OCS) and over-use of short-acting beta-2-agonists (SABA) are factors associated with adverse side effects and asthma-related death. We aim to quantify high OCS exposure, SABA over-use and its association with prescription and adherence to maintenance treatment for respiratory disease, among patients with prescriptions for respiratory disease, from the Portuguese electronic prescription and dispensing database (BDNP).

Methods

This was a 1-year (2016) retrospective population-based analysis of a random sample of adult patients from the BDNP, the nationwide compulsory medication prescription system. We assessed high OCS exposure (dispensing ≥ 4 packages containing 20 doses of 20 mg each of prednisolone-equivalent, ≥ 1600 mg/year) on patients on persistent respiratory treatment (PRT-prescription for > 2 packages of any respiratory maintenance medications). Excessive use of SABA was defined as having a ratio of SABA-to-maintenance treatment > 1 or having SABA over-use (dispensing of > 1 × 200 dose canister/month, of 100 μg of salbutamol-equivalent). Factors associated with high OCS exposure were assessed by multinomial logistic regression.

Results

The estimated number of patients on PRT was 4786/100,000 patients. OCS was prescribed to more than 1/5 of the patients on PRT and 101/100,000 were exposed to a high-dose (≥ 1600 mg/year). SABA excessive use was found in 144/100,000 patients and SABA over-use in 24/100,000. About 1/6 of SABA over-users were not prescribed any controller medication and 7% of them had a ratio maintenance-to-total ≥ 70% (high prescription of maintenance treatment). Primary adherence (median%) to controller medication was 66.7% for PRT patients, 59.6% for patients exposed to high OCS dose and 75.0% for SABA over-users. High OCS exposure or SABA over-use were not associated with primary adherence. High OCS exposure was associated with a maintenance-to-total medication ratio < 70% (insufficient prescription of maintenance treatment), age > 45 years old and male sex.

Conclusions

Exposure to high-dose of OCS (101 per 100,000 patients) and SABA over-use (24 per 100,000) were frequent, and were associated with a low maintenance-to-total prescription ratio but not with primary non-adherence. These results suggest there is a need for initiatives to reduce OCS and SABA inappropriate prescribing.

Changing prescribing behaviours with educational outreach: an overview of evidence and practice

BACKGROUND

General practitioners (GPs), or family practitioners, are tasked with prescribing medications that can be harmful to the community if they are inappropriately prescribed or used (e.g. opioids). Educational programs, such as educational outreach (EO), are designed to change the behaviour of health professionals. The purpose of this study was to identify the efficacy of EO programs at changing the prescribing behaviour of GPs.

METHODS

This study included an evidence and practice review, comprising a rapid review supplemented by interviews with people who are familiar with EO implementation for regulation purposes. Seven databases were searched using terms related to health professionals and prescribing. Systematic and narrative reviews published in English after 2007 were included. Non-statistical analysis was used to report intervention efficacy. Three government representatives participated in semi-structured interviews to aid in understanding the relevance of review findings to the Victorian context. Interviews were transcribed verbatim and thematically analysed for emerging themes.

RESULTS

Fourteen reviews were identified for the evidence review. Isolated (e.g. EO program delivered by itself) and multifaceted (e.g. EO program supplemented by other interventions) programs were found to change prescribing behaviours. However, limited evidence suggests that EO can successfully change prescribing behaviours specific to GPs. Isolated EO can successfully change health professional prescribing behaviours, although cheaper alternatives such as letters might be just as effective. Multifaceted EO can also successfully change health professional prescribing behaviours, especially in older adults, but it remains unclear as to what combination of interventions works best. Success factors for EO reported by government representatives included programs having practical rather than didactic foci; making EO compulsory; focussing EO on preventing adverse events; using monetary or professional development incentives; and in-person delivery.

CONCLUSIONS

Educational outreach can successfully change prescribing behaviours but evidence specific to GPs is lacking. Key characteristics of EO that could optimise success include ensuring the EO program is tailored, involves practical learning and uses incentives that are meaningful to clinicians.
