Interventions to Address Potentially Inappropriate Prescriptions and Over-The-Counter Medication Use Among Adults 65 Years and Older in Primary Care Settings: Protocol for a Systematic Review

Purpose: To inform recommendations by the Canadian Task Force on Preventive Health Care on potentially inappropriate prescribing and over-the-counter (OTC) medication use among adults aged 65 years and older in primary care settings. This protocol outlines the planned scope and methods for a systematic review of the benefits and harms and acceptability of interventions to reduce potentially inappropriate prescriptions and OTC medication use.Methods: De novo systematic reviews will be conducted to synthesize the available evidence on (a) the benefits and harms of interventions to reduce potentially inappropriate prescriptions and OTC medications compared to no intervention, usual care, or non- or minimally-active intervention among adults aged 65 years and older and (b) the acceptability of these interventions or attributes among patients. Outcomes of interest for the benefits and harms review are all-cause mortality, hospitalization, non-serious adverse drug reactions, quality of life, emergency department visits, injurious falls, medical visits, and the number of medications (and number of pills). Outcomes for the acceptability review are the preference for and relative importance of different interventions or their attributes. For the benefits and harms review, we will search MEDLINE, Embase, and Cochrane Central Register of Controlled Trials for randomized controlled trials. For the acceptability review, we will search MEDLINE, Embase, PsycInfo, Cochrane Central Register of Controlled Trials, and the NHS Economic Evaluation Database for experimental and observational studies with a comparator. Websites of relevant organizations, other grey literature sources, and reference lists of included studies and reviews will be searched. Title and abstract screening will be completed by two independent reviewers using the liberal accelerated approach. Full-text review, data extraction, risk of bias assessments, and GRADE (Grading of Recommendations Assessment, Development andEvaluation) will be completed independently by two reviewers, with any disagreements resolved by consensus or by consulting with a third reviewer. The GRADE approach will be used to assess the certainty of the evidence for outcomes.Discussion: The results of this systematic review will be used by the Canadian Task Force on Preventive Health Care to inform their recommendation on potentially inappropriate prescribing and OTC medication use among adults aged 65 years and older.Systematic review registration: PROSPERO (KQ1: CRD [tbd]; KQ2: CRD [tbd]); Open Science Framework (link TBD).

Analysis of the potential inappropriate use of medications in pediatric outpatients in China

Background The appropriate use of medications is essential in children. Yet, detailed information on how drugs are being prescribed and dispensed to pediatric populations is not documented in China. Aim The study objective was to analyze the details of medicine use and categorize the types of inappropriate use of medications on children. Methods A retrospective cross-sectional study was conducted on the prescriptions of pediatric outpatients aged < 18 years from 2019 to 2020 at a major Chinese tertiary academic center. Each age group’s demographic and clinical characteristics were collected, and the ratios of inappropriate prescriptions were analyzed. Results The total number of pediatric outpatients was 652,152, and 49.37% (322000) were prescribed medications, in which the most widely used medicines were respiratory, anti-infectives, and Traditional Chinese Medicines (TCMs). The prevalence rate of inappropriate prescriptions reached 20.49%, and in 2019 it was higher (21.71%) than that in 2020 (18.36%). The top three common inappropriate categories were indication-related off-label drug use, improper administration frequency, and overdosing, accounting for 67.93, 17.80 and 11.06% of all inappropriate prescriptions, respectively. The inappropriate prescriptions were more likely seen in patients aged 2–5 years and respiratory medicines. Conclusions The study findings indicate that inappropriate drug use in pediatric outpatients is still common, and great attention needs to be paid. More prospective trials are required to identify the effectiveness, safety, and necessity of off-label drug use of medicines in children.

Defining Potentially Inappropriate Prescriptions for Hypoglycaemic Agents to Improve Computerised Decision Support: A Study Protocol

In France, around 5% of the general population are taking drug treatments for diabetes mellitus (mainly type 2 diabetes mellitus, T2DM). Although the management of T2DM has become more complex, most of these patients are managed by their general practitioner and not a diabetologist for their antidiabetics treatments; this increases the risk of potentially inappropriate prescriptions (PIPs) of hypoglycaemic agents (HAs). Inappropriate prescribing can be assessed by approaches that are implicit (expert judgement based) or explicit (criterion based). In a mixed, multistep process, we first systematically reviewed the published definitions of PIPs for HAs in patients with T2DM. The results will be used to create the first list of explicit definitions. Next, we will complete the definitions identified in the systematic review by conducting a qualitative study with two focus groups of experts in the prescription of HAs. Lastly, a Delphi survey will then be used to build consensus among participants; the results will be validated in consensus meetings. We developed a method for determining explicit definitions of PIPs for HAs in patients with T2DM. The resulting explicit definitions could be easily integrated into computerised decision support tools for the automated detection of PIPs.

A retrospective study on the evaluation of the appropriateness of oral anticoagulant therapy for patients with atrial fibrillation

Background The incidence of atrial fibrillation (AF) is increasing, and effective anticoagulation therapy can prevent adverse events. Selecting the appropriate OAC based on patient characteristics has become a challenge. Interventions are going to be a potential area of focus. Objectives To explore the discrepancies between clinician prescriptions and recommended guidelines of oral anticoagulants (OACs) for patients with atrial fibrillation (AF), and to provide direction for improving anticoagulation strategies for treating patients with AF. Materials and methods Data were collected from the electronic medical record system of Fuwai Yunnan Cardiovascular Hospital between July 2019 and January 2020. The suitability of prescribed OACs for patients with AF was assessed according to the Rules for Avoiding Prescription Inappropriateness, the prescribed medicine label, and any relevant antithrombotic guidelines for treating patients with AF. Results A total of 460 patients met the inclusion criteria. Of these, 53.7% received an appropriate prescription and 46.3% received an inappropriate prescription. Of the patients who received inappropriate prescriptions, 15.4% were prescribed without the presenting appropriate indicators, 1.3% were prescribed inappropriate drug selection, and 29.6% were prescribed inappropriate drug doses. For patients prescribed without providing appropriate indicators, 2.2% had no indication for medication and 13.3% had an indication for medication, but not a specific OAC. For patients with inappropriate drug selection, 1, 5 patients were on rivaroxaban, dabigatran respectively. The distribution of NOAC doses was as follows: dabigatran standard dose (45.2%), the low dose (54.8%). Rivaroxaban standard dose (58.9%), low dose (36.8%), high dose (4.3%). A total of 44 patients (9.6%) experienced bleeding events, 12 patients (2.6%) experienced embolic events, and 7 patients experienced other adverse events after dosing. Conclusions In clinical practice, it is common for patients with AF to receive inappropriate prescriptions of OACs. Therefore there is a need to enhance anticoagulation management in patients with AF to improve the appropriate use of OACs.

Factors associated with potentially inappropriate prescriptions and barriers to medicines optimisation among older adults in primary care settings: a systematic review

ObjectiveTo identify factors that likely contribute to potentially inappropriate prescriptions (PIPs) among older adults in primary care settings, as well as barriers to medicines optimisation and recommended potential solutions.DesignSystematic review.Eligibility criteriaQuantitative studies that analysed the factors associated with PIPs among older adults (≥65 years) in primary care settings, and qualitative studies that explored perceived barriers and potential solutions to medicines optimisation for this population.Information sourcesPubMed, EMBASE, Scopus, CINAHL, PsycINFO, Web of Science, CNKI and Wanfang.ResultsOf the 13 167 studies identified, 50 were included (14 qualitative, 34 cross-sectional and 2 cohort). Nearly all quantitative studies examined patient-related non-clinical factors (eg, age) and clinical factors (eg, number of medications) and nine studies examined prescriber-related factors (eg, physician age). A greater number of medications were identified as positively associated with PIPs in 25 quantitative studies, and a higher number of comorbidities, physical comorbidities and psychiatric comorbidities were identified as patient-related clinical risk factors for PIPs. However, other factors showed inconsistent associations with the PIPs. Barriers to medicines optimisation emerged within four analytical themes: prescriber related (eg, inadequate knowledge, concerns of adverse consequences, clinical inertia, lack of communication), patient related (eg, limited understanding, patient non-adherence, drug dependency), environment related (eg, lack of integrated care, insufficient investment, time constraints) and technology related (eg, complexity of implementation and inapplicable guidance). Recommended potential solutions were based on each theme of the barriers identified accordingly (eg, prescriber-related factors: incorporating training courses into continuing medical education).ConclusionsOlder adults with more drugs prescribed and comorbidities may have a greater risk of receiving PIPs in the primary care setting, but it remains unclear whether other factors are related. Barriers to medicines optimisation among primary care older adults comprise multiple factors, and evidence-based and targeted interventions are needed to address these difficulties.PROSPERO registration numberCRD42020216258.

A qualitative study of the perception of nursing home practitioners about the implementation of quality indicators for drug consumption in nursing homes

Introduction Nursing homes (NHs) are an ideal environment in which to implement interventions aimed at reducing inappropriate prescriptions. Quality indicators (QIs) may be useful to standardize practices, but it is unclear how they mediate change. In the framework of a quantitative study aimed at reducing the prescription of anticholinergic drugs among NH residents using QIs, we performed a qualitative study to describe the investigators’ perception of the utility of QIs. Methods Qualitative study using focus group methodology. Focus groups were recorded and transcribed, and analyzed by thematic analysis. Participants were purposefully recruited from among the medical directors of the NHs in the quantitative study. Results Five medical directors participated in two focus group meetings. The main themes to emerge were: (1) communication is key to introducing new practices and achieving lasting uptake; (2) improved coordination and communication provided useful information to help interpret the quantitative results observed: e.g., participants reported that they were able to obtain contextual and patient-specific information that explained why some prescribers had consistently, but justifiably “poor” performance on the quantitative indicators; (3) negative aspects reported included reluctance to change among prescribers and the tendency to shirk responsibility. Conclusion From the point of view of medical directors of NHs participating in an interventional program to reduce inappropriate prescriptions of anticholinergic drugs, the main factor driving the success of the program was communication, which is key to achieving adherence. Improved communication provides useful insights into the reasons why no quantitative reduction is observed in objective quality indicators.

Potentially inappropriate prescriptions of antipsychotic and anticholinergic drugs in patients with Parkinson's disease

Aim: The objective was to determine the prevalence of the potentially inappropriate antipsychotics and anticholinergics used in patients with Parkinson's disease. Materials & methods: A cross-sectional study identified the prescription of antipsychotics, anticholinergics and drugs for the treatment of Parkinson's disease. The anticholinergic burden was evaluated, and quetiapine and clozapine were considered to be adequate antipsychotics. Results: 2965 patients with Parkinson's disease were identified. The presence of psychiatric disorders and other neurological pathologies was associated with a greater probability of receiving potentially inappropriate antipsychotic prescriptions. The presence of greater number of comorbidities was associated with a greater probability of receiving anticholinergics. Conclusion: Older age and associated comorbidities, especially psychiatric and neurological comorbidities, increase the likelihood of patients with Parkinson's disease being prescribed antipsychotics and anticholinergics.
