Effect of Pharmacist-Led Training on Adherence and Practice of Inhaler Use: A Pre-Post Interventional Study in Outpatients With Asthma at Hue University Hospital.

Objective This study aimed to evaluate the impact of a pharmacist-led intervention on improving adherence and practice of inhaler use in outpatients with asthma at a hospital in Vietnam. Methods A pre-post interventional study was conducted at Hue University Hospital. An adapted checklist for both metered-dose inhalers and/or dry powder inhalers was used to evaluate the inhaler technique. Adherence was assessed by using the Test of Adherence to Inhalers questionnaire. The means of interventions comprised "Face-to-face training," "Creating the leaflet for patients," and "Watching guidance video." Results The number of participants with complete data was 79. Before the intervention, 54.4% of patients had misused inhalers, especially inappropriate posture when using devices (70.2%) and not exhaling before inhalation (46.8%). Non-adherence accounted for 55.7% of patients, and the erratic pattern was the highest, with 83.5%. The intervention had remarkably raised the number of good practice and good adherence patients after three months (P < 0.001). Conclusion Pharmacist-led intervention has a positive impact on improving the adherence to inhalers and inhalation techniques of patients with asthma. Practice Implications The pharmacist-led education model could be considered as an effective and feasible solution for asthma management in outpatients and better medication use. Key Points (1) The most frequently observed mistakes in this study were inappropriate posture and inhalation skill when using devices. (2) Pharmacist-led training remarkably improved patients' practice of inhaler use as well as medication adherence.

Abstract WP240: Long Term Impact of the Los Angeles Barbershop Blood Pressure Study on Stroke/TIA and Cognitive Impairment

Background: Individuals with poorly controlled blood pressure (BP) have a heightened risk of stroke and vascular cognitive impairment. BP reduction has been associated with reduced risk of future stroke and cognitive impairment. Black Americans are disproportionately affected by hypertension and neurologic-target organ damage. Interventions targeted to reduce these disparities are greatly needed. From 2/2015 - 7/2017, 307 Black men were enrolled into a cluster randomised, pharmacist-led BP reduction intervention at 52 Black-owned barbershops in Los Angeles, CA [the Los Angeles Barbershop BP Study (LABBPS)] which demonstrated significant improvement in BP control sustained over a 12-month period. The current study evaluates the long-term impact of the intervention on incident stroke/TIA and prevalent mild cognitive impairment (MCI). Methods: Living participants from the LABBPS were contacted via telephone for interval health history inquiring about the development of symptoms consistent with stroke/TIA since trial end and via telephone interview for Cognitive Status (TICS-M); whereby a score ≤34 was considered positive for possible amnestic MCI. Rates of stroke/TIA were compared using a Pearson’s Chi-squared test. Results: Out of 288 participants, 115 men (50%) with mean (SD) age 62 (9) years, were successfully contacted a median of 6 years after trial end. The distribution of TICS-M scores was similar between groups with 71% and 70% having an abnormal result in the intervention and control groups respectively. Self-reported stroke/TIA occurred in 4 men in the intervention group and 9 in the control group (p = 0.13). Conclusion: Barbershop-based interventions have proven effective in lowering BP in Black men, a group at disparate risk for neurovascular complications. The preliminary results of our follow-up study do not show a significant difference in possible MCI between treatment arms, though there was a trend towards lower incident stroke/TIA seen in the intervention group. Limitations include a lack of interval BP values, unknown durability of the intervention beyond 12 months, and disproportionate impact of COVID-19 pandemic on the health of African American communities which is not accounted for in this analysis.

Evaluation of a Pharmacist-Led Implementation of Standardized Medication Administration Times for Inpatients Receiving Hemodialysis.

Missed medication doses are a common and often preventable medication-related error that have been associated with an increased length of stay and mortality. Hemodialysis is a common, relatively predictable reason that patients are unavailable, resulting in missed doses. To evaluate the implications of a pharmacist-led intervention to standardize the medication administration times for patients requiring hemodialysis who were prescribed antihypertensives, antiepileptics, apixaban, and/or antimicrobials. A retrospective preanalysis and postanalysis of a pharmacist-led intervention were performed at a single-center, safety net hospital. Patients receiving dialysis and prescribed one of the targeted medications were included. The primary endpoint was the composite of missed and delayed doses. A total of 25 patients receiving 126 dialysis sessions in the preintervention group and 29 patients receiving 80 dialysis sessions in the postintervention group were included for analysis. For the primary endpoint, 118 (18%) versus 57 (9.3%) doses were missed or delayed in the preintervention versus postintervention group, respectively (P < 0.001). The primary endpoint was driven by fewer delayed doses in the postgroup. The number of antimicrobials given on a correct schedule increased in the postintervention group (98.3% vs 99.1%, P = 0.044). A pharmacist-led intervention for standard medication administration times in patients requiring hemodialysis increased the number of prescribed medication doses given and given on time. The intervention also led to more antimicrobials administered at appropriate times relative to dialysis sessions.

Impact of a pharmacist-led educational intervention on knowledge, attitude, and practice toward the rational use of antibiotics among healthcare workers in a secondary care hospital in Punjab, Pakistan.

Introduction: Growing antimicrobial resistance (AMR) and decreasing efficacy of the available antimicrobials have become a significant public health concern. The antimicrobial stewardship program (ASP) ensures the appropriate use of antimicrobials and mitigates resistance prevalence through various interventions. One of the core components of the ASP is to educate healthcare workers (HWs). Therefore, this study aims to identify the impact of a pharmacist-led educational intervention targeting knowledge, attitude, and practices regarding rational antibiotic use among healthcare professionals in a secondary care hospital in Punjab. Methods: This is a single-center, questionnaire-based, pre-post interventional study conducted over a six-month time period. Data analysis was conducted using SPSS version 26. Results: Regarding the pre-interventional knowledge, attitude, and practice (KAP) score of the respondents, 90.3% had a good knowledge score, 81.5% had a positive attitude, and 72.3% of HWs (excluding doctors) had a good practice score. Additionally, 74.6% of the doctors had a good practice score. After educational intervention, there was a significant improvement in the knowledge, attitude, and practice of the respondent HWs (p-value <0.001). Furthermore, males have higher knowledge scores compared to females in the pre- and post-intervention stages (p-value <0.05), and doctors differ from nurses regarding knowledge scores in both pre- and post-intervention stages. Conclusion: Considering educational programs as the backbone of the ASP, it is imperative to sustain efforts in the ongoing educational programs of HWs to foster high awareness and adherence to the ASP among HWs.

Pharmacist-led intervention for older people with atrial fibrillation in long-term care (PIVOTALL study): a randomised pilot and feasibility study

BackgroundOlder care home residents are a vulnerable group of people with atrial fibrillation (AF) at high risk of adverse health events. The Atrial Fibrillation Better Care (ABC: Avoid stroke; Better symptom management; Cardiovascular and other comorbidity management) pathway is the gold-standard approach toward integrated AF care, and pharmacists are a potential resource with regards to its’ implementation. The aim of this study was to determine the feasibility of pharmacist-led medicines optimisation in care home residents, based on the ABC pathway compared to usual care.MethodsIndividually randomised, prospective pilot and feasibility study of older (aged ≥ 65 years) care home residents with AF (ISRCTN14747952); residents randomised to ABC pathway optimised care versus usual care. The primary outcome was a description of study feasibility (resident and care home recruitment and retention). Secondary outcomes included the number and type of pharmacist medication recommendations and general practitioner (GP) implementation.ResultsTwenty-one residents were recruited and 11 (mean age [standard deviation] 85.0 [6.5] years, 63.6% female) were randomised to receive pharmacist-led medicines optimisation. Only 3/11 residents were adherent to all three components of the ABC pathway. Adherence was higher to ‘A’ (9/11 residents) and ‘B’ (9/11 residents) components compared to ‘C’ (3/11 residents). Four ABC-specific medicines recommendations were made for three residents, and two were implemented by residents’ GPs. Overall ABC adherence rates did not change after pharmacist medication review, but adherence to ‘A’ increased (from 9/11 to 10/11 residents). Other ABC recommendations were inappropriate given residents’ co-morbidities and risk of medication-related adverse effects.ConclusionsThe ABC pathway as a framework was feasible to implement for pharmacist medication review, but most residents’ medications were already optimised. Low rates of adherence to guideline-recommended therapy were a result of active decisions not to treat after assessment of the net risk–benefit.

Characteristics of the clinical pharmacists' interventions at the main general tertiary care hospital in Qatar.

Medication-related problems (MRPs) are prevalent throughout healthcare systems, whereby pharmacy-based interventions are pivotal to reducing occurrence. In the Middle East, including Qatar, the professional roles of pharmacists have been expanding to improve patient safety. This study aimed to characterize and analyze pharmacist-led interventions among hospitalized patients in the leading general hospital in Qatar. A retrospective analysis of pharmacist interventions in the internal medicine ward, critical care unit, and emergency department (ED) was conducted. Data were extracted from three periods of 1 month (March 1-31, 2018, July 15-August 15, 2018, and January 1-31, 2019). A descriptive type of analysis was undertaken. A total of 340 patients with 858 interventions were analyzed. The average age of the study participants was 51 years (SD ± 17.7). The study population was predominantly male (65%). The prevailing pharmacist intervention was adding drug therapy (27%), followed by medication discontinuation (18%) and dosage adjustments (16%). This pattern was maintained across all subpopulations, e.g., gender, age, and ward, except for the ED, where cessation of medication was the most frequent intervention (4%). The two pharmacological classes associated with most interventions were anti-infective and cardiovascular agents. Pharmacist interventions effectively identify, prevent, and resolve MRPs in general inpatient settings in Qatar.

A multicentral prospective cohort trial of a pharmacist-led nutritional intervention on serum potassium levels in outpatients with chronic kidney disease: The MieYaku-Chronic Kidney Disease project.

Although dietary potassium restriction is an acceptable approach to hyperkalemia prevention, it may be insufficient for outpatients with chronic kidney disease (CKD). Most outpatients with CKD use community pharmacies owing to the free access scheme in Japan. The MieYaku-CKD project included a community pharmacist-led nutritional intervention for dietary potassium restriction, with the goal of determining its efficacy for patients' awareness of potassium restriction and serum potassium levels in outpatients with CKD. This was a five-community pharmacy multicenter prospective cohort study with an open-label, before-and-after comparison design. Eligible patients (n = 25) with an estimated glomerular filtration rate (eGFR) < 45 mL/min/1.73 m2 received nutritional guidance from community pharmacists. The primary outcome was a change in serum potassium levels at 12 weeks post-intervention. The eligible patients' knowledge, awareness, and implementation of potassium restriction were evaluated using a questionnaire. The median value of serum potassium was significantly reduced from 4.7 mEq/L before to 4.4 mEq/L after the intervention [p < 0.001, 95% confidence interval (CI): 0.156-0.500], with no changes in eGFR (p = 0.563, 95% CI: -2.427-2.555) and blood urine nitrogen/serum creatinine ratio (p = 0.904, 95% CI: -1.793-1.214). The value of serum potassium had a tendency of attenuation from 5.3 to 4.6 mEq/L (p = 0.046, 95% CI: 0.272-1.114) in the eGFR < 30 mL/min/1.73 m2 group. A questionnaire revealed that after the intervention, knowledge and attitudes regarding dietary potassium restriction were much greater than before, suggesting that the decrease in serum potassium levels may be related to this nutritional guidance. Our findings indicate that implementing a dietary potassium restriction guidance program in community pharmacies is feasible and may result in lower serum potassium levels in outpatients with CKD.

Interventions and impact of pharmacist-delivered services in perioperative setting on clinically important outcomes: a systematic review and meta-analysis.

The perioperative arena is a unique and challenging environment that requires coordination of the complex processes and involvement of the entire care team. Pharmacists' scope of practice has been evolving to be patient-centered and to expand to variety of settings including perioperative settings. To critically appraise, synthesize, and present the available evidence of the characteristics and impact of pharmacist-led interventions on clinically important outcomes in the perioperative settings. A systematic review and meta-analysis. We searched PubMed, Embase, and CINAHL from index inception to September 2023. Included studies compared the effectiveness of pharmacist-led interventions on clinically important outcomes (e.g. length of stay, readmission) compared to usual care in perioperative settings. Two independent reviewers extracted the data using the DEPICT-2 (Descriptive Elements of Pharmacist Intervention Characterization Tool) and undertook quality assessment using the Crowe Critical Appraisal (CCAT). A random-effect model was used to estimate the overall effect [odds ratio (OR) for dichotomous and standard mean difference (SMD) for continuous data] with 95% confidence intervals (CIs). Twenty-five studies were eligible, 20 (80%) had uncontrolled study design. Most interventions were multicomponent and continuous over the perioperative period. The intervention components included clinical pharmacy services (e.g. medication management/optimization, medication reconciliation, discharge counseling) and education of healthcare professionals. While some studies provided a minor description in regards to the intervention development and processes, only one study reported a theoretical underpinning to intervention development. Pooled analyses showed a significant impact of pharmacist care compared to usual care on length of stay (11 studies; SMD -0.09; 95% CI -0.49 to -0.15) and all-cause readmissions (8 studies; OR 0.60; 95% CI 0.39-0.91). The majority of included studies (n = 21; 84%) were of moderate quality. Pharmacist-led interventions are effective at improving clinically important outcomes in the perioperative setting; however, most studies were of moderate quality. Studies lacked the utilization of theory to develop interventions; therefore, it is not clear whether theory-derived interventions are more effective than those without a theoretical element. Future research should prioritize the development and evaluation of multifaceted theory-informed pharmacist interventions that target the whole surgical care pathway.

PHARMACIST INTERVENTION IS ASSOCIATED WITH MEDICATION ADHERENCE IN OLDER ADULTS WITH CHRONIC CONDITIONS

Abstract Hypertension, hyperlipidemia, and type 2 diabetes (T2D) are prevalent chronic diseases among older Americans, but related medication adherence rates are less than optimal. Consequences of poor adherence include increased mortality, healthcare utilization, and costs. Compounding evidence supports the integration of pharmacists in patients’ care across the care continuum. This study’s purpose was to examine the impact of a large national pharmacy chain’s pharmacist-led interventions to improve medication adherence among older adults with hypertension, hyperlipidemia, or T2D. Participants were Medicare D patients who had ≥2 prescription fills in ≥1 of the three therapeutic classes. The primary outcome, optimal adherence (OA), was defined as proportion of days covered (PDC) ≥80%. A difference-in-differences (DID) design with a generalized linear model approach was applied to examine differences between participants exposed to the intervention and controls across the study period (2020-2022). At baseline, intervention participants (n=317,613, age 70.1, female 57.0%) had lower OA for diabetes (76.9% vs. 79.8%), hypertension (79.0% vs. 83.0%), and cholesterol (78.6% vs. 82.1%) compared to controls (n=943.389, age 73.3, female 56.1%). The DID results showed that between 2020 - 2022, OA had significant absolute increases for intervention participants (diabetes: +4.0%, hypertension: +6.3%, cholesterol: +6.1%) versus controls (diabetes: -1.6%, hypertension: -0.4%, cholesterol: -1.4%). All DID models were significant at p&amp;lt; 0.0001. The pharmacist-led intervention was significantly associated with increased OA over 2 years. These findings reinforce the potential for pharmacists as care providers among older adults with chronic conditions. Future research should examine the expansion of pharmacist-provided care.

Impact of a pharmacist-led patient-centred care intervention along with textmessage reminders, on the management of newly diagnosed tubercular patients: A protocol for a randomized controlled trial.

Non-adherence to tuberculosis (TB) treatment is the leading cause of the increase in drug resistance cases. This study will determine the effectiveness of pharmaceutical-care-based interventions coupled with short messages delivered by a pharmacist on treatment outcomes and adherence among TB patients. The study will be conducted in TB Control Center of Pakistan Institute of Medical Sciences Hospital, Islamabad and District Bannu TB Control Center time period will be from August 2019 to September 2021. The patients will be included into the control group (usual care) or the intervention group pharmaceutical care and SMS reminder. The primary outcome includes a change in mean score from baseline in treatment outcomes and adherence, measured by Morisky Medication Adherence Scale, and clinic appointment attendance registration. Secondary outcomes include health-related quality of life of patients, disease knowledge, and patient satisfaction with the intervention. The major issues in patients with TB are cure rate and medication adherence. The method anticipated in this manuscript could set the foundation of pharmaceutical care and mobile SMS for the future provision of care to improve TB treatment outcomes. The study will make available fundamental information about the influence of the patient centered program on the adherence and clinical outcomes of patients with TB.Trial status and registration: Clinical Trials.gov assigned Identifier NCT04645836.

Pharmacist-led interventions in optimising the use of oral anticoagulants in patients with atrial fibrillation in general practice in England: a retrospective observational study.

Oral anticoagulation (OAC) is the mainstay of treatment for the prevention of strokes in patients with atrial fibrillation (AF). Direct oral anticoagulants (DOACs) account for increasing OAC in patients with AF. However, prescribing DOACs for patients with established AF poses various challenges and general practice pharmacists may have an important role in supporting their management. To investigate the effectiveness of pharmacist-led interventions in general practice in optimising the use of OAC therapies in AF. A retrospective observational study in general practices in Bradford. The data were collected retrospectively from 1 November 2018-31 December 2019 using electronic health record data. The data were analysed: 1) to identify patients with AF not on OAC; 2) to describe inappropriate DOAC prescriptions; and 3) to calculate HAS-BLED scores. Overall, 76.3% (n = 470) of patients with AF received OAC therapy, and of these, 63.4% received DOACs. Pharmacist-led interventions increased DOAC prescribing by 6.0% (P = 0.03). Inappropriate DOAC use was identified in 24.5% of patients with AF, with underdosed and overdosed identified in 9.7% and 14.8%, respectively. Post-intervention, inappropriate prescribing was reduced to 1.7%. The mean HAS-BLED score decreased from 3.00 to 2.22 (P<0.01). Successful transition from vitamin K antagonist (VKA) therapy to DOACs was achieved in 25.7% of patients. Pharmacist-led interventions have successfully improved the use of OAC therapies in patients with AF, and effectively managed the bleeding risks and transition from VKA to DOAC therapy, in line with guidelines.

The Role of Clinical Pharmacists in Antimicrobial Stewardship Programs (ASPs): A Systematic Review.

Antimicrobial resistance (AMR) is a major global health threat, increasing deaths and healthcare costs. Antimicrobial stewardship programs (ASPs) have been implemented to optimize antibiotic use and curb resistance. This systematic review aimed to summarize evidence on the role and impact of pharmacists in hospital ASPs. A comprehensive literature search was conducted across databases to identify relevant studies published from 2016 to 2023. Twenty-four studies met the inclusion criteria, comprising global observational and randomized clinical trials. Pharmacists performed various stewardship activities, including prospective audits, formulary management, de-escalation, guideline development, and education. Pharmacist-led interventions significantly improved antibiotic prescribing, reduced unnecessary antibiotic use, optimized therapy, and enhanced outcomes. Multiple studies found that pharmacist reviews decreased the time to optimal antibiotics and improved guideline compliance without affecting readmissions or revisits. De-escalation programs safely reduced antibiotic duration and length of stay. Acceptance rates for recommendations were high. Pharmacist stewardship curbed overall antibiotic use, costs, and duration across hospital departments, leading to savings. While most studies showed positive impacts, fewer detected significant changes in resistance or mortality over short periods. More research is needed, but current evidence demonstrates that pharmacists play critical roles in ASPs, leading to improved antibiotic use and patient outcomes. These findings support integrating pharmacists into stewardship activities, significantly extending programs to ambulatory settings.

The Effect of Pharmacist-Initiated Deprescribing Interventions in Older People: A Narrative Review of Randomized Controlled Trials.

Background Polypharmacy is common among older people and may be associated with adverse drug events (ADEs) and poor health outcomes. Pharmacists are well-positioned to reduce polypharmacy and potentially inappropriate medications. Objective The objective of this narrative review was to summarize the results from randomized-controlled trials that evaluated pharmacist-led interventions with the goal or effect to deprescribe medications in older individuals. Data Sources We searched Medline, Embase, CINAHL Complete, APA PsycInfo, Web of Science Core Collection, and Cochrane Central Register of Controlled Trials. Data Synthesis Of the 25 studies included, the interventions were conducted in nursing facilities (n = 8), outpatient/community dwellings (n = 8), or community pharmacies (n = 9). Interventions were categorized as comprehensive medication reviews (n = 10), comprehensive medication reviews with pharmacist follow-up (n = 11), and educational interventions provided to patients and/or providers (n = 4). Pharmacist-led interventions had a beneficial effect on 22 out of 32 total medication-related outcomes (eg, number of medications, potentially inappropriate medications, or discontinuation). Most (n = 18) studies reported no evidence of an effect for other outcomes such as health care use, mortality, patient-centered outcomes (falls, cognition, function, quality of life), and ADEs. Discussion Interventions led to improvement in 69% of the medication-related outcomes examined across study settings. Five studies measured ADEs with none accounting for adverse drug-withdrawal events. Large well-designed studies that are powered to find an effect on patient-centered outcomes are needed. Conclusion Pharmacist-led interventions had a significant beneficial effect on medication-related outcomes. There was little evidence of benefit on other outcomes.

Identifying racial disparities in the management of heart failure with reduced ejection fraction

Objective(s)Heart failure (HF) is chronic and progressive. Individuals with a left ventricular ejection fraction (LVEF or EF) < 40% are classified as having heart failure with reduced ejection fraction (HFrEF). Black patients have the highest incidence of HF and are more likely to suffer serious consequences from the disease. Identifying and addressing racial disparities in care is vital to ensuring health equity. The primary objective was to determine the association of race with 1-year heart HF admission rates for white and black patients, when adjusted for EF and age. The secondary objective was to determine the proportion of patients not on guideline-directed medication therapy (GDMT). DesignThis study was a retrospective chart review conducted between 10/22/2021 and 11/22/2022 of Veteran patients with HFrEF who were identified via the VA Heart Failure Dashboard. Only White and Black patients were included. A multivariable logistic regression was used to determine odds of admission due to HF. Pharmacotherapy was analyzed to identify gaps in GDMT and if racial disparities existed. Setting and participantsVeterans within the Veterans Affairs Western New York Healthcare System. Outcome measuresOne-year HF admission rates for white and black patients, when adjusted for EF and age. Proportion of patients not on GDMT. ResultsOf the 345 patients with HF originally identified, 172 were included; 22% were admitted within one year. Black patients were 2.9 times more likely to be admitted. (P = 0.031). A median of two drugs (interquartile range [IQR] 1-3) could be added and one dose could be optimized (IQR 1-4) to reach GDMT goals. No differences were found in the prescribing of GDMT or in proportion of patients not on GDMT at recommended doses between white and black patients. ConclusionBlack patients were more likely to be admitted for HF than white patients. Pharmacists can play an important role in identifying the need for optimizing GDMT. Future studies could focus on pharmacist-led prospective interventions with an aim to close the gap in racial disparities.

Medication use quality and safety in older adults: 2022 update.

Improving the quality of medication use and medication safety are important priorities for healthcare providers who care for older adults. The objective of this article was to identify four exemplary articles with this focus in 2022. We selected high-quality studies from an OVID search and hand searching of major high impact journals that advanced the field of research forward. The chosen articles cover domains related to deprescribing, medication safety, and optimizing medication use. The MedSafer Study, a cluster randomized clinical trial in Canada, evaluated whether patient specific deprescribing reports generated by electronic decision support software resulted in reduced adverse drug events in the 30 days post hospital discharge in older adults (domain: deprescribing). The second study, a retrospective cohort study using data from Premier Healthcare Database, examined in-hospital adverse clinical events associated with perioperative gabapentin use among older adults undergoing major surgery (domain: medication safety). The third study used an open-label parallel controlled trial in 39 Australian aged-care facilities to examine the effectiveness of a pharmacist-led intervention to reduce medication-induced deterioration and adverse reactions (domain: optimizing medication use). Lastly, the fourth study engaged experts in a Delphi method process to develop a consensus list of clinically important prescribing cascades that adversely affect older persons' health to aid clinicians to identify, prevent, and manage prescribing cascades (domain: optimizing medication use). Collectively, this review succinctly highlights pertinent topics related to promoting safe use of medications and promotes awareness of optimizing older adults' medication regimens.

The Care Home Independent Pharmacist Prescriber Study (CHIPPS): development and implementation of an RCT to estimate safety, effectiveness and cost-effectiveness

Background Medicine prescribing, monitoring and administration in care homes can be significantly enhanced. Effective interventions to improve pharmaceutical care and resident outcomes are required. The enablement of pharmacists to prescribe provides an opportunity for pharmacist independent prescribers to assume responsibility for improving pharmaceutical care, medication-related outcomes and resident safety whilst reducing general practitioner workload. Objective(s) To determine the effectiveness and cost-effectiveness of pharmacist independent prescribing in care homes. Design Development work was undertaken through five work packages before the delivery of the definitive trial. Triads of pharmacist independent prescribers, care home and general practice with responsibility over 20 care home residents were recruited and cluster randomised to intervention or usual care for 6 months. Researchers were blinded at recruitment stage only. Recruitment of 880 residents was required to provide 80% statistical power, to show a 21% reduction in falls over 6 months, assuming 20% attrition. Randomisation was undertaken electronically at triad level, stratified by geographical area. Intention-to-treat analysis undertaken using a negative binomial model. Parameters were estimated using a generalised estimating equation approach. Costs were captured from an NHS perspective. Quality of life (EuroQol; five domain; five level) was collected by proxy to enable cost/quality-adjusted life-year estimation. A concurrent process evaluation was performed. Safety was monitored through a review of pharmacist independent prescriber activities, independent concerns reporting and review of adverse events. Participants Forty-nine triads of general practitioners, pharmacist independent prescribers and care homes were recruited with 454 residents allocated to the intervention arm and 428 to the control arm. Intervention Medication review and care planning, medication reconciliation, staff training, support with care home medication-related procedures, deprescribing and authorisation of monthly prescriptions. Main outcome measure Fall rate per person over 6 months. Results Data for 449 intervention and 427 control residents available for final analysis. The 6-month fall rate ratio in favour of intervention was 0.91 (95% confidence interval 0.66 to 1.26; p=0.58). No significant difference in secondary outcomes was identified except Drug Burden Index (rate ratio 0.83, 95% confidence interval 0.75 to 0.92; p&lt;0.001). No harms were identified. One quarter of medication-related interventions were associated with a reduced risk of falls. The intervention was positively received. Limitations Participant self-selection bias may have affected the generalisability of findings. Open-label cluster randomised controlled trial limited by 6-month follow-up. Potential ceiling effect due to concurrent pharmacist-led interventions. Falls potentially insufficiently proximal to the intervention. Conclusions To enhance effectiveness and acceptance of the proposed model, effective integration into care home and general practitioner teams was identified as a central requirement. A core outcome set and a training package were developed. The final model of care, whilst being safe and well received and resulting in a reduction in drug burden, demonstrated no improvement in the primary outcome of falls. With no improvement in quality-adjusted life-years identified, the pharmacist independent prescriber intervention was not estimated to be cost-effective. Future work To develop and evaluate better models of care for enhancing medication outcomes and safety in care homes or re-test with a longer intervention and follow-up period and a stronger primary outcome.
