Factors influencing prescribing of fall-risk-increasing drugs to the elderly: A qualitative study

Development of the ADFICE_IT clinical decision support system to assist deprescribing of fall-risk increasing drugs: A user-centered design approach

INTRODUCTION

Deprescribing fall-risk increasing drugs (FRIDs) is promising for reducing the risk of falling in older adults. Applying appropriate deprescribing in practice can be difficult due to the outcome uncertainties associated with stopping FRIDs. The ADFICE_IT intervention addresses this complexity with a clinical decision support system (CDSS) that facilitates optimum deprescribing of FRIDs by using a fall-risk prediction model, aggregation of deprescribing guidelines, and joint medication management.

METHODS

The development process of the CDSS is described in this paper. Development followed a user-centered design approach in which users and experts were involved throughout each phase. In phase I, a prototype of the CDSS was developed which involved a literature and systematic review, European survey (n = 581), and semi-structured interviews with clinicians (n = 19), as well as the aggregation and testing of deprescribing guidelines and the development of the fall-risk prediction model. In phase II, the feasibility of the CDSS was tested by means of two usability testing rounds with users (n = 11).

RESULTS

The final CDSS consists of five web pages. A connection between the Electronic Health Record allows for the retrieval of patient data into the CDSS. Key design requirements for the CDSS include easy-to-use features for fast-paced clinical environments, actionable deprescribing recommendations, information transparency, and visualization of the patient's fall-risk estimation. Key elements for the software include a modular architecture, open source, and good security.

CONCLUSION

The ADFICE_IT CDSS supports physicians in deprescribing FRIDs optimally to prevent falls in older patients. Due to continuous user and expert involvement, each new feedback round led to an improved version of the system. Currently, a cluster-randomized controlled trial with process evaluation at hospitals in the Netherlands is being conducted to test the effect of the CDSS on falls. The trial is registered with ClinicalTrials.gov (date; 7-7-2022, identifier: NCT05449470).

Antihypertensive treatment in people of very old age with frailty: time for a paradigm shift?

The optimal management of hypertension in individuals aged 80 years or older with frailty remains uncertain due to multiple gaps in evidence. Complex health issues, polypharmacy, and limited physiological reserve make responding to antihypertensive treatments unpredictable. Patients in this age group may have limited life expectancy, so their quality of life should be prioritized when making treatment decisions. Further research is needed to identify which patients would benefit from more relaxed blood pressure targets and which antihypertensive medications are preferable or should be avoided. A paradigm shift is required in attitudes towards treatment, placing equal emphasis on deprescribing and prescribing when optimizing care. This review discusses the current evidence on managing hypertension in individuals aged 80 years or older with frailty, but further research is essential to address the gaps in knowledge and improve the care of this population.

Prescribing patterns of fall risk-increasing drugs in older adults hospitalized for heart failure

BACKGROUND

Older adults hospitalized for heart failure (HF) are at risk for falls after discharge. One modifiable contributor to falls is fall risk-increasing drugs (FRIDs). However, the prevalence of FRIDs among older adults hospitalized for HF is unknown. We describe patterns of FRIDs use and examine predictors of a high FRID burden.

METHODS

We used the national biracial REasons for Geographic and Racial Differences in Stroke (REGARDS) study, a prospective cohort recruited from 2003-2007. We included REGARDS participants aged ≥ 65 years discharged alive after a HF hospitalization from 2003-2017. We determined FRIDs -cardiovascular (CV) and non-cardiovascular (non-CV) medications - at admission and discharge from chart abstraction of HF hospitalizations. We examined the predictors of a high FRID burden at discharge via modified Poisson regression with robust standard errors.

RESULTS

Among 1147 participants (46.5% women, mean age 77.6 years) hospitalized at 676 hospitals, 94% were taking at least 1 FRID at admission and 99% were prescribed at least 1 FRID at discharge. The prevalence of CV FRIDs was 92% at admission and 98% at discharge, and the prevalence of non-CV FRIDs was 32% at admission and discharge. The most common CV FRID at admission (88%) and discharge (93%) were antihypertensives; the most common agents were beta blockers (61% at admission, 75% at discharge), angiotensin-converting enzyme inhibitors (36% vs. 42%), and calcium channel blockers (32% vs. 28%). Loop diuretics had the greatest change in prevalence (53% vs. 72%). More than half of the cohort (54%) had a high FRID burden (Agency for Healthcare Research and Quality (AHRQ) score ≥ 6), indicating high falls risk after discharge. In a multivariable Poisson regression analysis, the factors strongly associated with a high FRID burden at discharge included hypertension (PR: 1.41, 95% CI: 1.20, 1.65), mood disorder (PR: 1.24, 95% CI: 1.10, 1.38), and hyperpolypharmacy (PR: 1.88, 95% CI: 1.64, 2.14).

CONCLUSIONS

FRID use was nearly universal among older adults hospitalized for HF; more than half had a high FRID burden at discharge. Further work is needed to guide the management of a common clinical conundrum whereby guideline indications for treating HF may contribute to an increased risk for falls.

Exploring Older Adult Health Literacy in the Day-to-Day Management of Polypharmacy and Making Decisions About Deprescribing: A Mixed Methods Study

BACKGROUND

Polypharmacy use in older adults is increasing and sometimes leads to poor health outcomes. The influence of health literacy in managing polypharmacy and making decisions about stopping medication has received limited attention.

OBJECTIVE

A mixed methods design was used to measure and investigate the influence of health literacy in the management of polypharmacy and decisions about deprescribing. Phase 1 involved two cross-sectional surveys, one with older adults using five or more medications and the other with general practitioners (GPs).

METHODS

Older adult health literacy was measured using the All Aspects of Health Literacy Scale. Phase 2 employed individual interviews with both older adults and GPs and further explored the reported use of health literacy in practice. SPSS version 24 was used to conduct descriptive statistical analysis of the Phase 1 survey responses and Phase 2 interviews were analyzed using thematic analysis with the assistance of NVivo 12.

KEY RESULTS

Phase 1 survey responses were received from 85 GPs and 137 older adults. Phase 2 interviews were conducted with 16 GPs and 25 older adults. Phase 1 results indicated that self-reported older adult health literacy was high, and that GPs believed older patients could engage in decisions about deprescribing. Phase 2 findings showed that older adults developed and employed complex health literacy practices to manage medications between consultations; however, few reported using their health literacy skills in consultations with their GPs. GPs noted that older adult involvement in decision-making varied and generally thought that older adults had low health literacy.

CONCLUSION

Older adults reported using health literacy practices in the management of their sometimes-complex medication regimens. However, the role of health literacy in deprescribing decision-making was limited. The mixed methods approach allowed greater insight into older adult and GP practices that influence the acquisition and use of health literacy. [HLRP: Health Literacy Research and Practice. 2023;7(1):e14-e25.] Plain Language Summary: This report explores health literacy in the use of multiple medications and decisions to stop using medication/s in older age. Older adults reported good heath literacy and practiced many health literacy skills in the management of their medications. However, they did not always report the use of their health literacy skills when discussing their medications with their family doctor.

Barriers and facilitators in using a Clinical Decision Support System for fall risk management for older people: a European survey

PURPOSE

Fall-Risk Increasing Drugs (FRIDs) are an important and modifiable fall-risk factor. A Clinical Decision Support System (CDSS) could support doctors in optimal FRIDs deprescribing. Understanding barriers and facilitators is important for a successful implementation of any CDSS. We conducted a European survey to assess barriers and facilitators to CDSS use and explored differences in their perceptions.

METHODS

We examined and compared the relative importance and the occurrence of regional differences of a literature-based list of barriers and facilitators for CDSS usage among physicians treating older fallers from 11 European countries.

RESULTS

We surveyed 581 physicians (mean age 44.9 years, 64.5% female, 71.3% geriatricians). The main barriers were technical issues (66%) and indicating a reason before overriding an alert (58%). The main facilitators were a CDSS that is beneficial for patient care (68%) and easy-to-use (64%). We identified regional differences, e.g., expense and legal issues were barriers for significantly more Eastern-European physicians compared to other regions, while training was selected less often as a facilitator by West-European physicians. Some physicians believed that due to the medical complexity of their patients, their own clinical judgement is better than advice from the CDSS.

CONCLUSION

When designing a CDSS for Geriatric Medicine, the patient's medical complexity must be addressed whilst maintaining the doctor's decision-making autonomy. For a successful CDSS implementation in Europe, regional differences in barrier perception should be overcome. Equipping a CDSS with prediction models has the potential to provide individualized recommendations for deprescribing FRIDs in older falls patients.

Deprescribing Medications that Increase the Risk of Falls in Older People: Exploring Doctors' Perspectives Using the Theoretical Domains Framework (TDF)

BACKGROUND

Falls can lead to hospitalisation and death in older people. Polypharmacy is a major risk factor, and deprescribing fall-risk increasing drugs (FRIDs) is one of several possible important preventive measures. The objective of this study was to explore the factors that influence doctors when deprescribing FRIDs in a hospital setting.

METHOD

Semi-structured interviews were conducted with consultant geriatricians and hospital doctors experienced in dealing with patients aged 65 years or older, at a large academic teaching hospital (~ 1000 beds), Dublin, Ireland. The interviews were directed by an interview guide and audio recorded and transcribed verbatim, with subsequent thematic analysis in NVivo 12 software.

RESULTS

A total of 18 participants were interviewed. Barriers to deprescribing included: insufficient time, incomplete patient records, changing medications initiated by other specialists and difficulties following up patients after discharge. Facilitators included: enhanced documentation through electronic patient records, the support of other healthcare professionals such as clinical pharmacists, and patients' engagement, which is considered essential for the success of the deprescribing process's outcome.

CONCLUSION

Deprescribing FRIDs in older adults in the hospital setting is challenging. Implementation of the process in practice requires combined effort from stakeholders to tackle everyday work environment challenges. Future studies are required examining the clinical effect of the suggested interventions and exploring patients' involvement in deprescribing decisions.

ADHERENCE AND BARRIERS TO DRUG THERAPY: RELATIONSHIP WITH THE RISK OF FALLS IN OLDER ADULTS

ABSTRACT Objective: to verify the association of adherence and barriers to drug therapy with the risk of falls and the sociodemographic, clinical and economic variables. Method: a cross-sectional study, carried out with 117 aged individuals in a Medical Clinic of Specialties for Older Adults in the Southeast region of the city of São Paulo (SP), from March to November 2019. The following scales were applied: Downton Fall Risk, Morisky-Green Test and Brief Medication Questionnaire. Logistic regression was use to verify the association between adherence to the treatment and types of barriers to adherence and the risk of falls. A 5% significance level was used. Results: the older adults with low adherence to the drug treatment presented 5.57 times more chances of having a high risk of falling when compared to those with greater adherence, and those with a barrier in the recall domain had 22.75 times more chances of having a high risk of falling, in relation to the aged individuals without barriers in the recall domain. Conclusion: low and average adherence to drug therapy and the barrier related to the recall domain were associated with high risk of falls in the older adults.

Determinants for the use and de-implementation of low-value care in health care: a scoping review

BACKGROUND

A considerable proportion of interventions provided to patients lack evidence of their effectiveness. This implies that patients may receive ineffective, unnecessary or even harmful care. However, despite some empirical studies in the field, there has been no synthesis of determinants impacting the use of low-value care (LVC) and the process of de-implementing LVC.

AIM

The aim was to identify determinants influencing the use of LVC, as well as determinants for de-implementation of LVC practices in health care.

METHODS

A scoping review was performed based on the framework by Arksey and O'Malley. We searched four scientific databases, conducted snowball searches of relevant articles and hand searched the journal Implementation Science for peer-reviewed journal articles in English. Articles were included if they were empirical studies reporting on determinants for the use of LVC or de-implementation of LVC. The abstract review and the full-text review were conducted in duplicate and conflicting decisions were discussed until consensus was reached. Data were charted using a piloted data charting form and the determinants were inductively coded and categorised in an iterative process conducted by the project group.

RESULTS

In total, 101 citations were included in the review. Of these, 92 reported on determinants for the use of LVC and nine on determinants for de-implementation. The studies were conducted in a range of health care settings and investigated a variety of LVC practices with LVC medication prescriptions, imaging and screening procedures being the most common. The identified determinants for the use of LVC as well as for de-implementation of LVC practices broadly concerned: patients, professionals, outer context, inner context, process and evidence and LVC practice. The results were discussed in relation to the Consolidated Framework for Implementation Research.

CONCLUSION

The identified determinants largely overlap with existing implementation frameworks, although patient expectations and professionals' fear of malpractice appear to be more prominent determinants for the use and de-implementation of LVC. Thus, existing implementation determinant frameworks may require adaptation to be transferable to de-implementation. Strategies to reduce the use of LVC should specifically consider determinants for the use and de-implementation of LVC.

Why do they do it? A grounded theory study of the use of low-value care among primary health care physicians

Background

The use of low-value care (LVC) is widespread and has an impact on both the use of resources and the quality of care. However, few studies have thus far studied the factors influencing the use of LVC from the perspective of the practitioners themselves. The aim of this study is to understand why physicians within primary care use LVC.

Methods

Six primary health care centers in the Stockholm Region were purposively selected. Focus group discussions were conducted with physicians (n = 31) working in the centers. The discussions were coded inductively using a grounded theory approach.

Results

Three main reasons for performing LVC were identified. Uncertainty and disagreement about what not to do was related to being unaware of the LVC status of a practice, guidelines perceived as conflicting, guidelines perceived to be irrelevant for the target patient population, or a lack of trust in the guidelines. Perceived pressure from others concerned patient pressure, pressure from other physicians, or pressure from the health care system. A desire to do something for the patients was associated with the fact that the visit in itself prompts action, symptoms to relieve, or that patients' emotions need to be reassured. The three reasons are interdependent. Uncertainty and disagreement about what not to do have made it more difficult to handle the pressure from others and to refrain from doing something for the patients. The pressure from others and the desire to do something for the patients enhanced the uncertainty and disagreement about what not to do. Furthermore, the pressure from others influenced the desire to do something for the patients.

Conclusions

Three reasons work together to explain primary care physicians’ use of LVC: uncertainty and disagreement about what not to do, perceived pressure from others, and the desire to do something for the patients. The reasons may, in turn, be influenced by the health care system, but the decision nevertheless seemed to be up to the individual physician. The findings suggest that the de-implementation of LVC needs to address the three reasons from a systems perspective.

Pharmacists' knowledge and counselling on fall risk increasing drugs in a tertiary teaching hospital in Nigeria

BACKGROUND

Falls and fall-related injuries are a foremost health concern among older adults aged 60 years and above. Fall-risk-increasing drugs (FRIDs) use by older adults is one related cause of falling, and it is frequently used among older adults. Pharmacist-led counselling is an aspect of patient education that has been associated with improved therapeutic outcome and quality of life in high income countries with scarcity of information in low-middle income countries. This study therefore aims to assess hospital pharmacists' knowledge and counselling on fall-related medications using the list compiled by the Swedish National Board of Health and Welfare on FRIDs and orthostatic drugs (ODs).

METHODS

A cross-sectional survey was carried out among 56 pharmacists working in a teaching hospital in Nigeria, between July and August 2019, using a self-administered questionnaire. Data were summarized with descriptive statistics while chi-square test was used for categorical variables at p < 0.05.

RESULTS

Thirty-five (62.5%) were within 10 years of practice experience. Two-third (62.5%) of the pharmacists possessed an additional qualification to Bachelor of Pharmacy degree. Twenty-two (40.0%) were aware of the FRIDs and ODs list. In all, (89.3%) had "unsatisfactory" knowledge of classes of medications and specific medicines that could cause a fall. Most pharmacists 42 (80.8%) focused counsel on appropriate medication use, adverse effects of drugs and storage of medications. Knowledge score of both FRIDs and ODs were neither significantly associated with pharmacists' years of qualification (χ2 = 1.282; p = 0.733), (χ2 = 2.311; p = 0.510) nor with possession of additional qualification (χ2 = 0.854; p = 0.836), (χ2 = 2.996; p = 0.392). Majority, 53 (98.1%) believed that patients will benefit from effective counselling on FRIDs and ODs. About half (25; 51.0%) suggested training through seminar presentation as a measure for FRIDs and ODs sensitization.

CONCLUSION

A substantial gap in knowledge and awareness of FRIDs and ODs was noted among the hospital pharmacists. However, engagement of pharmacists on counsel that focus on medication use, adverse effect and storage was relatively better. Thus, there is a general need to create awareness about fall-risk-increasing drugs among hospital pharmacists, so as to help improve the therapeutic outcome particularly in the older adults.

Modification of Potentially Inappropriate Prescribing Following Fall-Related Hospitalizations in Older Adults

BACKGROUND

There is strong evidence that potentially inappropriate prescribing is associated with falls in older adults. Fall-related hospitalizations should trigger medication review.

OBJECTIVES

The aim of this before-and-after cohort study was to explore patterns of relevant potentially inappropriate prescribing in older people with fall-related hospitalizations.

METHODS

Data on older adults with hospitalizations for falls, fractures and syncope between 2012 and 2016 were collected from 44 general practices in Ireland. Fall-related prescribing was defined from the Screening Tool for Older Persons' Prescriptions (sedatives and vasodilators) and the Screening Tool to Alert doctors to Right Treatment (vitamin D). Prevalence of prescriptions were estimated from general practice and hospital discharge records. Mixed-effects logistic regression was conducted to compare the 12-month pre- and post-hospitalization periods.

RESULTS

Overall, 927 individuals (68% female, average age 81.2 years; standard deviation 8.6) were included, 45% of whom had a diagnosis of fracture, 28% had syncope, and 27% had a fall without fracture/syncope. After adjustment for covariates and practice clustering effects, both vitamin D and sedatives had higher odds of prescription post-hospitalization (adjusted odds ratio [aOR] 4.47, 95% confidence interval [CI] 2.09-9.54, and aOR 1.75, 95% CI 1.29-2.39, respectively). With adjustments for age and sex, having a fracture was associated with new initiation of vitamin D (aOR 2.81, 95% CI 1.76-4.46) and having syncope was associated with continuing on vasodilators (aOR 1.99, 95% CI 1.06-3.74). No factors were associated with new sedative initiation.

CONCLUSION

Fall-related potentially inappropriate prescribing is prevalent in older adults who have a history of falls, and continues after discharge from hospital. Future studies should investigate why such prescribing is initiated after a fall-related hospitalization, and explore interventions that could reduce such hazardous prescribing.

Deprescribing for older adults in Australia: factors influencing GPs

Polypharmacy is increasing among older Australians, raising their risk of experiencing medication-related harm. As part of the prescribing continuum, deprescribing is a strategy proposed to reduce inappropriate polypharmacy. This study explored factors that influence deprescribing among Australian GPs using a new 21-item survey to measure GP attitudes and practices. The 85 GP responses indicated that many factors are supportive of deprescribing. GPs suggest that they are willing to explore their older patients' deprescribing preferences; they believe that they have enough information about the potential harms and benefits of medication to inform their deprescribing decisions and are confident to communicate this information to their patients. GPs did not consider their patients would interpret deprescribing as being 'given up on'. Limited time to review medications, poor communication between prescribers and a perception that other prescribers do not respect their role as overall coordinators of their older patients' medications were considered by respondents to be unsupportive of deprescribing. Overall, despite GPs reporting many supportive factors for deprescribing, the influence of unsupportive factors appears to remain strong, as deprescribing is not routinely considered in practice.

Factors associated with alcohol consumption and prescribed drugs with addiction potential among older women and men - the Nord-Trøndelag health study (HUNT2 and HUNT3), Norway, a population-based longitudinal study

BACKGROUND

Little is known about factors associated with alcohol consumption and use of drugs with addiction potential in older adults. The aim of this study was to explore the association between socio-demographic variables, physical and mental health and the later (11 years) use of frequent drinking, prescribed drugs with addiction potential and the possible combination of frequent drinking and being prescribed drugs with addiction potential in older adults (≥ 65 years).

METHODS

In this longitudinal study, we used data from two surveys of the Nord-Trøndelag Health Study (HUNT2 1995-1997 and HUNT3 2006-2008), a population based study in Norway. We totally included 10,656 individuals (5683 women) aged 54 years and older when they participated in HUNT2. Frequent drinking was defined as drinking alcohol 4 days or more per week. Data on prescribed drugs with addiction potential were drawn from the Norwegian Prescription Database. Drugs with addiction potential were defined as at least one prescription of benzodiazepines, z-hypnotics or opioids during one year for a minimum of two consecutive years between 2005 and 2009.

RESULTS

The typical frequent drinker in HUNT3 was younger, more educated, lived in urban areas, and reported smoking and drinking frequently in HUNT2 compared to the non-frequent drinker in HUNT3. The typical user of prescribed drugs with addiction potential in HUNT3 was an older woman who smoked and was in poor health, suffered from anxiety, had been hospitalized in the last 5 years and used anxiety or sleep medication every week or more often in HUNT2. The typical individual in HUNT3 with the possible combination of frequent drinking and being prescribed drugs with addiction potential had more education, smoked, drank frequently and used anxiety or sleep medication in HUNT2.

CONCLUSION

Individuals who were identified as frequent drinkers in HUNT2 were more likely to be frequent drinkers in HUNT3, and to have the possible combination of frequent drinking and being prescribed drugs with addiction potential in HUNT3. Health care professionals need to be aware of use of alcohol among older adults using drugs with addiction potential.

EuGMS Task and Finish group on Fall-Risk-Increasing Drugs (FRIDs): Position on Knowledge Dissemination, Management, and Future Research

Falls are a major public health concern in the older population, and certain medication classes are a significant risk factor for falls. However, knowledge is lacking among both physicians and older people, including caregivers, concerning the role of medication as a risk factor. In the present statement, the European Geriatric Medicine Society (EuGMS) Task and Finish group on fall-risk-increasing drugs (FRIDs), in collaboration with the EuGMS Special Interest group on Pharmacology and the European Union of Medical Specialists (UEMS) Geriatric Medicine Section, outlines its position regarding knowledge dissemination on medication-related falls in older people across Europe. The EuGMS Task and Finish group is developing educational materials to facilitate knowledge dissemination for healthcare professionals and older people. In addition, steps in primary prevention through judicious prescribing, deprescribing of FRIDs (withdrawal and dose reduction), and gaps in current research are outlined in this position paper.

Health care professionals' attitudes towards deprescribing in older patients with limited life expectancy: A systematic review

AIMS

The aim of this systematic review was to explore health care professionals' attitudes towards deprescribing in older people with limited life expectancy.

METHODS

A systematic literature search was conducted from inception to December 2017 using MEDLINE, EMBASE and CINAHL. Studies were included if they specifically concerned older people (≥65 years) with limited life expectancy, including those residing in any type of aged care facility, or were based on representative patient profiles. Results were analyzed inspired by the Joanna Briggs Institute's method for synthesis of qualitative data. Studies were characterized using a checklist for reporting of qualitative research.

RESULTS

Eight studies were included. Six studies explored health care professionals' views on deprescribing in general, and two studies focused specifically on psychotropic agents. All eight studies explored the views of physicians, mostly general practitioners, while three studies also considered other health care professionals. Four themes related to health care professionals' attitudes towards deprescribing were identified: (i) patient and relative involvement; (ii) the importance of teamwork; (iii) health care professionals' self-assurance and skills; and (iv) the impact of organizational factors. Within each of these themes, 3-4 subthemes were identified and analysed.

CONCLUSIONS

Our results suggest that health care professionals' decisions to engage in deprescribing activities with older people with limited life expectancy depend on multiple factors which are highly interdependent. Consequently, there is an urgent need for more research on how to approach deprescribing in clinical practice within this population.

Deprescribing medications for older adults in the primary care context: A mixed studies review

AIMS

This review investigates the factors that influence deprescribing of medications in primary care from the perspective of general practitioners (GPs) and community-living older adults.

METHODS

A mixed studies review structure was adopted searching Scopus, CINAHL, PsychINFO, ProQuest, and PubMed from January 2000 to December 2017. A manual search of reference lists was also conducted. Studies were included if they were original research available in English and explored general deprescribing rather than deprescribing of a specific class of medications. The Mixed Methods Assessment Tool was used to assess the quality of studies, and content analysis generated common categories across studies.

RESULTS

Thirty-eight articles were included, and 7 key categories were identified. The review found that the factors that influence deprescribing are similar across and within health systems and mostly act as barriers. These factors remained unchanged across the review period. The structural organisation of health systems remains poorly suited to facilitate deprescribing. Individual knowledge gaps of both GPs and older adults influence practices and attitudes towards deprescribing, and significant communication gaps occur between GPs and specialists and between GPs and older adults. As a result, deprescribing decision making is characterised by uncertainty, and deprescribing is often considered only when medication problems have already arisen. Trust plays a complex role, acting as both a barrier and facilitator of deprescribing.

CONCLUSIONS

Deprescribing is influenced by many factors. Despite recent interest, little change has occurred. Multilevel strategies aimed at reforming aspects of the health system and managing uncertainty at the practice and individual level, notably reducing knowledge limitations and closing communications gaps, may achieve change.

General practitioners' prescriptions of benzodiazepines, Z-hypnotics and opioid analgesics for elderly patients during direct and indirect contacts. A cross-sectional, observational study

OBJECTIVE

To describe Norwegian general practitioners' (GPs') prescription patterns of benzodiazepines, Z-hypnotics and opioid analgesics (BZO-drugs) to elderly (≥70 years) patients.

DESIGN, SUBJECTS AND SETTING

Cross sectional, observational study. Contact- and prescription data from 148 Norwegian GPs, issued for elderly patients during eight months in 2008. GP-patient contacts were categorized as direct contacts (DC: face-to-face consultations) or indirect contacts (IC: via third party, phone or mail). Explanatory variables were characteristics linked to the GPs, patients, and practices. During analyses, GPs' number of listed patients, share of which for elderly patients, and total number of patient consultations during the period (proxy for practice activity), were categorized in quintiles (Q1-5) by number of GPs.

MAIN OUTCOME MEASURES

Number of BZO-drug prescriptions and quantities issued during direct- and indirect GP-patient contacts.

RESULTS

In total, 62% of BZO-prescriptions were issued during ICs. Of all prescriptions, 66% were large quantum packages (50 tablets or more), 62% out of which were prescribed during ICs. During the study period, 50% of the patients received repeat prescriptions. Prescribing during ICs was associated with low over all practice activity (Q1) and many (Q5) older patients on the GP's lists.

CONCLUSION

GPs' BZO-drug prescribing to elderly occur more frequently during ICs than within DCs, and are more commonly issued as large quantity packages. This indicates that regular- or long-term use among elderly is common, contrasting with previous and current national guidelines, which recommend regular clinical assessments and short time or intermittent use of BZO-drugs. Key Points GPs frequently prescribe benzodiazepines, Z-hypnotics and opioid (BZO) drugs for elderly people. BZO-drugs are frequently issued during indirect GP-patient contacts and in relatively large quantities, indicating regular or long-term use. GPs' BZO-drug prescribing patterns contrast with national guidelines recommending clinical assessment and short time or intermittent use of BZO-drugs.

Falls-Related Drug Use and Risk of Falls Among Older Adults: A Study in a US Medicare Population

Background

Approximately one-third of community-dwelling older adults fall each year, and approximately 10% have falls requiring medical services. Among other factors, research studies have linked certain medications with an increased risk of falls.

Objective

The aim of this study was to examine the risk of falls relative to use patterns among new and continuing falls-related drug (FRD) users.

Methods

A 10% random sample, insured in AARP^® Medicare Supplement and AARP Medicare Part D Rx plans, was utilized to define new and continuing FRD users. New users had a 12-month pre-period without FRD use, whereas continuing users had at least one FRD in the pre-period. Both groups had 12-month follow-up after initiating or continuing FRD use. Characteristics associated with the risk of falls for new and continuing users were determined using multivariate logistic regression models.

Results

Among insureds, 44% used at least one of the FRD classes. Of these, 29% were new users (N = 35,340) and 71% were continuing users (N = 121,488). Fall rates for the two subgroups were similar at 7 and 8%, respectively. Characteristics associated with the risk of falls were previous injurious fall, use of two or more classes of FRDs, older age, poorer health, and being female. New users were at higher risk than continuing users.

Conclusion

New users of FRDs were at highest risk of falls, and continuing users were at increased risk, especially with higher numbers of FRD classes. Both groups could benefit from falls awareness and prevention programs.

Elderly users of fall-risk-increasing drug perceptions of fall risk and the relation to their drug use - a qualitative study

OBJECTIVE

The aim of the study was to explore how home-dwelling elderly who use fall-risk-increasing drugs (FRIDs) perceive their fall risk and how they relate this to their drug use.

DESIGN, SETTING AND SUBJECTS

A qualitative study with 14 home-dwelling elderly FRID users between 65 and 97 years in Central Norway participating in semi-structured individual interviews. The data were analyzed thematically by using systematic text condensation.

RESULTS

The main finding was that the informants did not necessarily perceive the use of FRIDs to be a prominent risk factor for falls. Some informants said they did not reflect upon drug use whatsoever and said they fully trusted their physician's choices. When either experiencing dizziness, fall episodes or by reading the patient information leaflet the informants said to either adjust their drug use or to contact their physician. Some felt rejected due to not getting their point across or their wish to alter the drug was not granted by the physician.

CONCLUSIONS

Elderly FRID users did not necessarily relate their drug use to fall risk or struggled to present their perceived drug-related problems. Physicians need to regularly inform, monitor and assess the drug treatment when treating elderly with FRIDs.

Improving the appropriateness of antipsychotic prescribing in nursing homes: a mixed-methods process evaluation of an academic detailing intervention

BACKGROUND

In 2014, nursing home administration and government officials were facing increasing public and media scrutiny around the variation of antipsychotic medication (APM) prescribing across Ontario nursing homes. In response, policy makers partnered to test an academic detailing (AD) intervention to address appropriate prescribing of APM in nursing homes in a cluster-randomized trial. This mixed-methods study aimed to explore how and why the AD intervention may have resulted in changes in the nursing home context. The objectives were to understand how the intervention was implemented, explore contextual factors associated with implementation, and examine impact of the intervention on prescribing.

METHODS

Administrative data for the primary outcome of the full randomized trial will not be available for a minimum of 1 year. Therefore, this paper reports the findings of a planned, quantitative interim trial analysis assessed mean APM dose and prescribing prevalence at baseline and 3 and 6 months across 40 nursing homes (18 intervention, 22 control). Patient-level administrative data regarding prescribing were analyzed using generalized linear mixed effects regression. Semi-structured interviews were conducted with nursing home staff from the intervention group to explore opinions and experiences of the AD intervention. Interviews were analyzed using the framework method, with constructs from the Consolidated Framework for Implementation Research (CFIR) applied as pre-defined deductive codes. Open coding was applied when emerging themes did not align with CFIR constructs. Qualitative and quantitative findings were triangulated to examine points of divergence to understand how the intervention may work and to identify areas for future opportunities and areas for improvement.

RESULTS

No significant differences were observed in prescribing outcomes. A total of 22 interviews were conducted, including four academic detailers and 18 nursing home staff. Constructs within the CFIR domains of Outer Setting, Inner Setting, and Characteristics of Individuals presented barriers to antipsychotic prescribing. Intervention Source, Evidence Strength and Quality, and Adaptability explained participant engagement in the AD intervention; nursing homes that exhibited a Tension for Change and Leadership Engagement reported positive changes in processes and communication.

CONCLUSIONS

Participants described their experiences with the intervention against the backdrop of a range of factors that influence APM prescribing in nursing homes that exist at the system, facility, provider, and resident levels. In this context, the perceived credibility and flexibility of the intervention were critical features that explained engagement with and potential impact of the intervention. Development of a common language across the team to enable communication was reported as a proximal outcome that may eventually have an effect on APM prescribing rates. Process evaluations may be useful during early stages of evaluation to understand how the intervention is working and how it might work better. Qualitative results suggest the lack of early changes observed in prescribing may reflect the number of upstream factors that need to change for APM rates to decrease.

Nurses' and pharmacists' learning experiences from participating in interprofessional medication reviews for elderly in primary health care - a qualitative study

Background

Traditionally, drug prescription and follow up have been the sole responsibility of physicians. However, interprofessional medication reviews (IMRs) have been developed to prevent drug discrepancies and patient harm especially for elderly patients with polypharmacy and multimorbidity. What participating nurses and pharmacists learn from each other during IMR is poorly studied. The aim of this study was to investigate nurses’ and pharmacists’ perceived learning experience after participating in IMRs in primary health care for up to two years.

Methods

A qualitative study with semi-structured focus group interviews and telephone interviews with nurses and pharmacists with experience from IMRs in nursing homes and home based services. The data was analysed thematically by using systematic text condensation.

Results

Thirteen nurses and four pharmacists were interviewed. They described some challenges concerning how to ensure participation of all three professions and how to get thorough information about the patient. As expected, both professions talked of an increased awareness with time of the benefit of working as a team and the perception of contributing to better and more individual care. The nurses’ perception of the pharmacist changed from being a controller of drug management routines towards being a source of pharmacotherapy knowledge and a discussant partner of appropriate drug therapy in the elderly. The pharmacists became more aware of the nurses’ crucial role of providing clinical information about the patient to enable individual advice. Increasingly the nurses learned to link the patient’s symptoms of effect and side effect to the drugs prescribed.

Conclusions

Although experiencing challenges in conducting IMRs, the nurses and pharmacists had learning experiences they said improved both their own practice and the quality of drug management. There are some challenges concerning how to ensure participation of all three professions and how to get thorough information about the patient.

Usual care and management of fall risk increasing drugs in older dizzy patients in Dutch general practice

OBJECTIVE

For general practitioners (GPs) dizziness is a challenging condition to deal with. Data on the management of dizziness in older patients are mostly lacking. Furthermore, it is unknown whether GPs attempt to decrease Fall Risk Increasing Drugs (FRIDs) use in the management of dizziness in older patients. The aim of this study is to gain more insight into GP's management of dizziness in older patients, including FRID evaluation and adjustment.

DESIGN

Data were derived from electronic medical records, obtained over a 12-month period in 2013.

SETTING

Forty-six Dutch general practices.

PATIENTS

The study sample comprised of 2812 older dizzy patients of 65 years and over. Patients were identified using International Classification of Primary Care codes and free text.

MAIN OUTCOME MEASURES

Usual care was categorized into wait-and-see strategy (no treatment initiated); education and advice; additional testing; medication adjustment; and referral.

RESULTS

Frequently applied treatments included a wait-and-see strategy (28.4%) and education and advice (28.0%). Additional testing was performed in 26.8%; 19.0% of the patients were referred. Of the patients 87.2% had at least one FRID prescription. During the observation period, GPs adjusted the use of one or more FRIDs for 11.7% of the patients.

CONCLUSION

This study revealed a wide variety in management strategies for dizziness in older adults. The referral rate for dizziness was high compared to prior research. Although many older dizzy patients use at least one FRID, FRID evaluation and adjustment is scarce. We expect that more FRID adjustments may reduce dizziness and dizziness-related impairment. Key Points It is important to know how general practitioners manage dizziness in older patients in order to assess potential cues for improvement. This study revealed a wide variety in management strategies for dizziness in older patients. There was a scarcity in Fall Risk Increasing Drug (FRID) evaluation and adjustment. The referral rate for dizziness was high compared with previous research.

The Changed Injury Landscape, More on Injury Prevention Roles for the Lifestyle Physician, and More Than "Limited Progress" Since Injury in America

One theme of the article ("Time for Lifestyle Medicine to Take Injury Prevention Seriously," by Teitge and Francescutti) that should resonate with contemporary injury prevention proponents-whether they are researchers, practitioners, policy makers, or advocates in the public health arena or providers, administrators, and patient advocates in the health care arena-is the need for an increased injury prevention focus among health care providers. In particular, the call for providers to link injury prevention approaches and tools to the clinical care of patients is both noteworthy and compelling. However, the authors' description of the current injury experience in the United States fails to acknowledge important changes over the past decade and a half that have had an impact on the injury prevention roles of providers. Plus, the notion that progress in injury prevention has been limited in the 3 decades since the publication of Injury in America, undervalues the advances that have occurred.
