A pharmacist-physician intervention model using a computerized alert system to reduce high-risk medication use in primary care

Primary Care Provider-Led Approach to Deprescribing Potentially Inappropriate Medications in Older Adults

Potentially inappropriate medication (PIM) use increases the risk of adverse drug events in older adults and deprescribing has been shown to reduce these outcomes. This study assessed the feasibility of a provider-driven approach to deprescribe PIMs in an internal medicine clinic. Providers received education on the risks of select medications and benefits of deprescribing at an all-staff meeting in April 2021. Providers were asked to choose a deprescribing intervention. Chart reviews were completed at 3 and 6 months to evaluate changes in medication. Tests of binomial proportions were used to determine any significant differences. Thirty-two providers participated and interventions resulted in a 41.6% reduction in the reviewed PIMs (tapered or discontinued). A provider-driven approach may be a feasible and effective method of deprescribing PIMs in older adults.

Clinical validation of clinical decision support systems for medication review: A scoping review

The aim of this scoping review is to summarize approaches and outcomes of clinical validation studies of clinical decision support systems (CDSSs) to support (part of) a medication review. A literature search was conducted in Embase and Medline. In total, 30 articles validating a CDSS were ultimately included. Most of the studies focused on detection of adverse drug events, potentially inappropriate medications and drug‐related problems. We categorized the included articles in three groups: studies subjectively reviewing the clinical relevance of CDSS's output (21/30 studies) resulting in a positive predictive value (PPV) for clinical relevance of 4–80%; studies determining the relationship between alerts and actual events (10/30 studies) resulting in a PPV for actual events of 5–80%; and studies comparing output of CDSSs to chart/medication reviews in the whole study population (10/30 studies) resulting in a sensitivity of 28–85% and specificity of 42–75%. We found heterogeneity in the methods used and in the outcome measures. The validation studies did not report the use of a published CDSS validation strategy. To improve the effectiveness and uptake of CDSSs supporting a medication review, future research would benefit from a more systematic and comprehensive validation strategy.

The Prescription of Drug Ontology 2.0 (PDRO): More Than the Sum of Its Parts

While drugs and related products have profoundly changed the lives of people around the world, ongoing challenges remain, including inappropriate use of a drug product. Inappropriate uses can be explained in part by ambiguous or incomplete information, for example, missing reasons for treatments, ambiguous information on how to take a medication, or lack of information on medication-related events outside the health care system. In order to fully assess the situation, data from multiple systems (electronic medical records, pharmacy and radiology information systems, laboratory management systems, etc.) from multiple organizations (outpatient clinics, hospitals, long-term care facilities, laboratories, pharmacies, registries, governments) on a large geographical scale is needed. Formal knowledge models like ontologies can help address such an information integration challenge. Existing approaches like the Observational Medical Outcomes Partnership are discussed and contrasted with the use of ontologies and systems using them for data integration. The PRescription Drug Ontology 2.0 (PDRO 2.0) is then presented and entities that are paramount in addressing this problematic are described. Finally, the benefits of using PDRO are discussed through a series of exemplar situation.

Deprescribing intervention activities mapped to guiding principles for use in general practice: a scoping review

OBJECTIVE

To identify and characterise activities for deprescribing used in general practice and to map the identified activities to pioneering principles of deprescribing.

SETTING

Primary care.

DATA SOURCES

Medline, EMBASE (Ovid), CINAHL, Australian New Zealand Clinical Trials Registry (ANZCTR), Clinicaltrials.gov, ISRCTN registry, OpenGrey, Annals of Family Medicine, BMC Family Practice, Family Practice and British Journal of General Practice (BJGP) from inception to the end of June 2021.

STUDY SELECTION

Included studies were original research (randomised controlled trial, quasi-experimental, cohort study, qualitative and case studies), protocol papers and protocol registrations.

DATA EXTRACTION

Screening and data extraction was completed by one reviewer; 10% of the studies were independently reviewed by a second reviewer. Coding of full-text articles in NVivo was conducted and mapped to five deprescribing principles.

RESULTS

Fifty studies were included. The most frequently used activities were identification of appropriate patients for deprescribing (76%), patient education (50%), general practitioners (GP) education (48%), and development and use of a tapering schedule (38%). Six activities did not align with the five deprescribing principles. As such, two principles (engage practice staff in education and appropriate identification of patients, and provide feedback to staff about deprescribing occurrences within the practice) were added.

CONCLUSION

Activities and guiding principles for deprescribing should be paired together to provide an accessible and comprehensive guide to deprescribing by GPs. The addition of two principles suggests that practice staff and practice management teams may play an instrumental role in sustaining deprescribing processes within clinical practice. Future research is required to determine the most of effective activities to use within each principle and by whom.

Protocol of a tailored educational intervention for general practitioners on potentially inappropriate medications among older patients at community healthcare institutions in Beijing, China: a cluster-randomised controlled trial

INTRODUCTION

Prescribing of potentially inappropriate medications (PIMs) has become a prominent issue of public concern among elderly patients. However, no research has involved interventions on PIMs of Chinese elderly patients seeking care at primary healthcare. This study aims to evaluate the effectiveness of a tailored educational intervention programme for general practitioners (GPs), aiming at reducing the occurrence of PIMs in elderly patients.

METHODS AND ANALYSIS

This is a parallel group, controlled, cluster-randomised trial, with blinded evaluation of outcomes and data analysis, and un-blinded intervention. Twenty primary community healthcare stations (CHSs) in Dongcheng district in Beijing will be randomised to intervention and control arm with an allocation ratio of 1:1. GPs in CHSs randomised to the intervention arm will receive a two-component intervention: general training of PIMs and distribution of PIMs handbook. GPs in the control arm will assess and manage patients according to the institutions' routine practice. The primary outcome is the change in PIMs patient visit rate.

ETHICS AND DISSEMINATION

Ethics committee approval of this study was obtained from Peking University Institution Review Board (IRB00001052-19074). The findings will be published in scientific and conference presentations.

Community-based pharmacists' role in deprescribing: A systematic review

AIMS

Community-based pharmacists are an important stakeholder in providing continuing care for chronic multi-morbid patients, and their role is steadily expanding. The aim of this study is to examine the literature exploring community-based pharmacist-initiated and/or -led deprescribing and to evaluate the impact on the success of deprescribing and clinical outcomes.

METHODS

Library and clinical trials databases were searched from inception to March 2020. Studies were included if they explored deprescribing in adults, by community-based pharmacists and were available in English. Two reviewers extracted data independently using a pre-agreed data extraction template. Meta-analysis was not performed due to heterogeneity of study designs, types of intervention and outcomes.

RESULTS

A total of 24 studies were included in the review. Results were grouped based on intervention method into four categories: educational interventions; interventions involving medication review, consultation or therapy management; pre-defined pharmacist-led deprescribing interventions; and pharmacist-led collaborative interventions. All types of interventions resulted in greater discontinuation of medications in comparison to usual care. Educational interventions reported financial benefits as well. Medication review by community-based pharmacist can lead to successful deprescribing of high-risk medication, but do not affect the risk or rate of falls, rate of hospitalisations, mortality or quality of life. Pharmacist-led medication review, in patients with mental illness, resulting in deprescribing improves anticholinergic side effects, memory and quality of life. Pre-defined pharmacist-led deprescribing did not reduce healthcare resource consumptions but can contribute to financial savings. Short follow-up periods prevent evaluation of long-term sustainability of deprescribing interventions.

CONCLUSION

This systematic review suggests community-based pharmacists can lead deprescribing interventions and that they are valuable partners in deprescribing collaborations, providing necessary monitoring throughout tapering and post-follow-up to ensure the success of an intervention.

Potentially inappropriate medications among elderly patients in community healthcare institutions in Beijing, China

PURPOSE

To evaluate potentially inappropriate medications (PIMs) prevalence and predictors in community healthcare institutions (CHIs) for the elderly.

METHODS

We conducted a retrospective observational study, deriving data of patients aged ≥60 from 66 CHIs in Beijing, 2014-2018. The system of Criteria of PIM for Older Adults in China was applied to identify PIMs. The primary outcome was the prevalence of visits with at least one PIM; secondary outcomes were the frequency and rate per thousand visits of specific PIMs. We used descriptive analysis and generalized linear models to analyzed PIMs and the predictors, and marginal effects methods were applied to estimate the mean adjusted PIMs prevalence.

RESULTS

Overall, 4 528 884 elderly patient visits from 2014 to 2018 were eligible for inclusion. A total of 719 757 PIMs were detected, with 14.1% of the visits contained at least one PIM. PIM prevalence was significantly correlated with age, number of prescribed medications and number of diagnoses. Overall, 6.0 per thousand elderly patients in CHIs were exposed to at least one high-risk PIM, while 117.5 per thousand were exposed to at least one low-risk PIM. In 2018, 20% of GPs were responsible for more than half of overall PIM visits.

CONCLUSION

Prescribing of PIMs for older adults is common in CHIs in China, especially for patients who are aged, having multiple medications and diagnostic diseases. Strategies should be developed to enhance prescribing quality for geriatric patients, with special targeting of doctors responsible for a high number of PIMs.
