Effects of hospital pharmacist interventions on health outcomes in older polymedicated inpatients: a scoping review

[INTERPOLAR-prospective, interventional studies as part of the Medical Informatics Initiative to improve medication therapy safety in healthcare]

Medication analyses by ward pharmacists are an important measure of drug therapy safety (DTS). Medication-related problems (MRPs) are identified and resolved with the attending clinicians. However, staff resources for extended medication analyses and complete documentation are often limited. Until now, data required for the identification of risk patients and for an extended medication analysis often had to be collected from various parts of the institution's internal electronic medical record (EMR). This error-prone and time-consuming process is to be improved in the INTERPOLAR (INTERventional POLypharmacy-Drug interActions-Risks) project using an IT tool provided by the data integration centers (DIC).INTERPOLAR is a use case of the Medical Informatics Initiative (MII) that focuses on the topic of DTS. The planning phase took place in 2023, with routine implementation planned from 2024. DTS-relevant data from the EMR is to be presented and the documentation of MRPs in routine care is to be facilitated. The prospective multicenter, cluster-randomized INTERPOLAR‑1 study serves to evaluate the benefits of IT support in routine care. The aim is to show that more MRPs can be detected and resolved with the help of IT support. For this purpose, six normal wards will be selected at each of eight university hospitals, so that 48 clusters (with a total of at least 70,000 cases) are available for randomization.

Multifaceted pharmacist-led interventions in secondary care settings between countries of various income levels: a scoping review protocol

INTRODUCTION

Clinical pharmacy services often involve multifaceted pharmacist-led interventions. However, current pharmacy practice models vary across different countries. Despite the documented benefits of clinical pharmacy services, the characteristics of pharmacist-led interventions in different countries have not yet been adequately explored and described. Therefore, this protocol outlines the methodology for a proposed scoping review aiming to investigate various types of multifaceted pharmacist-led interventions and the outcomes used to evaluate their effectiveness within secondary care settings. Additionally, the scoping review will map the current evidence surrounding the characteristics of interventions and outcomes reported across various countries of socioeconomic status.

METHODS AND ANALYSIS

The scoping review will be conducted according to the JBI Methodology for Scoping Reviews and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) Extension for Scoping Reviews. We will systematically search the following electronic databases: MEDLINE (Ovid), CINAHL (EbscoHost), Embase (embase.com), Scopus (scopus.com), Cochrane Library (cochranelibrary.com) and APA PsycInfo (Ovid). Additionally, the reference lists of identified reviews and included full texts will be searched for relevant papers. Grey literature sources, such as International Pharmaceutical Abstracts and the International Pharmaceutical Federation (FIP) website, will be searched. We will include primary studies published in the English language from January 2013 to December 2023, involving secondary care multifaceted pharmacist-led interventions. Two independent reviewers will screen studies against eligibility criteria and use a piloted data extraction form to extract relevant information. We will extract relevant data, complete a tabular summary from each included publication and analyse it.

ETHICS AND DISSEMINATION

Ethical approval is not required as we will be using data from publicly available literature sources. Findings will be disseminated in publications and presentations with relevant stakeholders. We aim to map available evidence across the breadth of studies that have reported multifaceted pharmacist-led interventions and their outcomes.

Primary care pharmacist-led medication review in older adult patients in coordination with general practitioners: an observational retrospective cohorts study

Background

Polypharmacy and risk of potentially inappropriate prescribing (PIP) in older adult are being continuously increased. Including a primary care pharmacist (PCP) in the healthcare team is associated with lower rates of medication-related problems (MRPs).

Objectives

To determine the impact (in terms of variation of PIP, MRPs and polymedication) of treatment reviews (TR) carried out by the PCP by comparing two cohorts: standard TR vs coordinated TR with prescribing General Practitioners (GP). To assess possible health outcomes in both groups 6 months post-TR.

Methods

This is an observational study of two retrospective cohorts (2018 to 2020). All patients who met the inclusion/exclusion criteria were analyzed. Patients ≥65 years, who underwent complete TR by the PCP were included. Patients in a situation of exitus at the time of TR and those who underwent a partial TR were excluded. Control group cohort consisted of patients who underwent standard TR, and intervention group cohort consisted of those who underwent TR coordinated with GP. Sociodemographic, clinical and pharmacological variables were analyzed.

Results

181 patients were enrolled. Mean age 84.4 ± 7.2 years, 78.5% women. Variables (GP-coordinated vs standard TRs) pre-post: decrease in drugs/patient 1.9 (95%CI: 1.4-2.4) vs 0.6 (95%CI: 0.2-1.3), p < 0.05; decrease in MRPs/patient 3.1 (95%CI: 2.8-3.4) vs 1.0 (95%CI: 0.6-1.4), p < 0.05; decrease in PIP/patient 2.0 (95% CI: 1.6-2.2) vs 0.6 (95% CI: 0.2-0.9), p < 0.05. Health outcomes: there was significant difference in average primary-care visits/patient 1.3 ± 0.5 vs 2.2 ± 1.8, p < 0.05.

Conclusions

Multidisciplinary interventions between PCP and GP, together with a systematic approach to TR can improve the quality of pharmacotherapy in the elderly. Prospective large follow-up studies are needed to demonstrate a positive trend in health outcomes.

Haefeli W, M. Seidling H. Mortality and Hospitalizations Among Patients Enrolled in an Interprofessional Medication Management Program

BACKGROUND

Measures for improving medication safety in outpatient care are often complex and involve medication reviews. Over the period 2016-2022 (with a preceeding one-year pilot phase), an interprofessional medication management program- the Medicines Initiative Saxony-Thuringia (Arzneimittelinitiative Sachsen-Thüringen, ARMIN)-was implemented in two German federal states. More than 5000 patients received a medication review by the end of 2019 by a team composed of physicians and pharmacists and were provided with joint, continuous care thereafter.

METHODS

In the framework of a retrospectively registered cohort study, the mortality and hospitalizations of this population (5033 patients) were studied using routine data from a statutory health insurer (observation period 2015-2019) and compared with those of a control group (10 039 patients) determined from the routine data by propensity score matching. Mortality was compared by survival analysis (Cox regression), and hospitalization rates were compared in terms of event probabilities within two years of enrollment in the medication management program. Robustness was tested in multiple sensitivity analyses.

RESULTS

Over the observation period, 9.3% of the ARMIN participants and 12.9% of persons in the control group died (hazard ratio of the adjusted Cox regression, 0.84; 95% confidence interval [0.76; 0.94], P = 0.001). In the first two years after inclusion, the ARMIN participants were hospitalized just as often as the persons in the control group (52.4% versus 53.4%; odds ratio from the adjusted model, 1.04 [0.96; 1.11], P = 0.347). The effects were consistent in sensitivity analyses.

CONCLUSION

In this retrospective cohort study, participation in the ARMIN program was associated with a lower risk of death. Exploratory analyses provide clues to the potential origin of this association.

Research status and hotspots of medication safety in older adults: A bibliometric analysis

Background

Medication safety is a significant concern in healthcare. Research on medication safety for older adults has taken a broad approach, resulting in a range of proposals. At this juncture, it is necessary to identify the main contributors and establish the current developmental status of the principal research topics.

Objective

This study sets out to summarize the state-of-the-art in medication safety for older adults, identifying significant achievements, key topics, and emerging trends.

Methods

The Web of Science Core Collection (WOSCC) database was searched for relevant documentation over the interval 1st January 2000 to 31st December 2021. Annual outputs and citations were identified from the WOS citation reports. CiteSpace and VOSviewer were adopted for bibliometric analysis and visualization that included the distribution of countries/regions, organizations, authors and journals, and an analysis of co-cited references and keywords.

Results

A total of 1,638 documents were retrieved for bibliometric analysis, yielding 34.29 citations per document. Publications have increased over the past two decades, reaching 177 outputs in 2019. Our database encompasses 71 countries/regions, 2,347 organizations, and 7,040 authors. The United States ranks first in terms of scientific activity with 604 publications (36.87%). We have identified the University of Sydney as the most prolific organization (53 publications). J. T. Hanlon, J. H. Gurwitz, D. O'Mahony, and G. Onder are the most influential researchers in terms of publications and citations. The Journal of the American Geriatrics Society ranks first with 89 (5.43%) papers. In terms of major research directions, three topics have been identified from co-cited reference and keyword analysis: (1) estimation of the prevalence and variables associated with polypharmacy and potentially inappropriate medication; (2) analysis of interventions involving pharmacists and the associated impact; (3) patient experience and perception associated with medication use or pharmaceutical care.

Conclusion

Research on medication safety for older adults has progressed significantly over the past two decades. The United States, in particular, has made important contributions to this field. Polypharmacy and potentially inappropriate medication use, interventions involving pharmacists, patient experience and perception represent the current focus of research. Our findings suggest that these directions will continue as research hotspots in the future.

SPUR: A Patient-Reported Medication Adherence Model as a Predictor of Admission and Early Readmission in Patients Living with Type 2 Diabetes

PURPOSE

Poor medication adherence (MA) is linked to an increased likelihood of hospital admission. Early interventions to address MA may reduce this risk and associated health-care costs. This study aimed to evaluate a holistic Patient Reported Outcome Measure (PROM) of MA, known as SPUR, as a predictor of general admission and early readmission in patients living with Type 2 Diabetes.

PATIENTS AND METHODS

An observational study design was used to assess data collected over a 12-month period including 6-month retrospective and 6-month prospective monitoring of the number of admissions and early readmissions (admissions occurring within 30 days of discharge) across the cohort. Patients (n = 200) were recruited from a large South London NHS Trust. Covariates of interest included: age, ethnicity, gender, level of education, income, the number of medicines and medical conditions, and a Covid-19 diagnosis. A Poisson or negative binomial model was employed for count outcomes, with the exponentiated coefficient indicating incident ratios (IR) [95% CI]. For binary outcomes (Coefficient, [95% CI]), a logistic regression model was developed.

RESULTS

Higher SPUR scores (increased adherence) were significantly associated with a lower number of admissions (IR = 0.98, [0.96, 1.00]). The number of medical conditions (IR = 1.07, [1.01, 1.13]), age ≥80 years (IR = 5.18, [1.01, 26.55]), a positive Covid-19 diagnosis during follow-up (IR = 1.83, [1.11, 3.02]) and GCSE education (IR = 2.11, [1.15,3.87]) were factors associated with a greater risk of admission. When modelled as a binary variable, only the SPUR score (-0.051, [-0.094, -0.007]) was significantly predictive of an early readmission, with patients reporting higher SPUR scores being less likely to experience an early readmission.

CONCLUSION

Higher levels of MA, as determined by SPUR, were significantly associated with a lower risk of general admissions and early readmissions among patients living with Type 2 Diabetes.

Interdisciplinary collaboration across secondary and primary care to improve medication safety in the elderly (The IMMENSE study) - a randomized controlled trial

Background

Suboptimal medication use contributes to a substantial proportion of hospitalizations and emergency department visits in older adults. We designed a clinical pharmacist intervention to optimize medication therapy in older hospitalized patients. Based on the integrated medicine management (IMM) model, the 5-step IMMENSE intervention comprise medication reconciliation, medication review, reconciled medication list upon discharge, patient counselling, and post discharge communication with primary care. The objective of this study was to evaluate the effects of the intervention on healthcare use and mortality.

Methods

A non-blinded parallel group randomized controlled trial was conducted in two internal medicine wards at the University Hospital of North Norway. Acutely admitted patients ≥ 70 years were randomized 1:1 to intervention or standard care (control). The primary outcome was the rate of emergency medical visits (readmissions and emergency department visits) 12 months after discharge.

Results

Of the 1510 patients assessed for eligibility, 662 patients were asked to participate, and 516 were enrolled. After withdrawal of consent and deaths in hospital, the modified intention-to-treat population comprised 480 patients with a mean age of 83.1 years (SD: 6.3); 244 intervention patients and 236 control patients. The number of emergency medical visits in the intervention and control group was 497 and 499, respectively, and no statistically significant difference was observed in rate of the primary outcome between the groups [adjusted incidence rate ratio of 1.02 (95% CI: 0.82–1.27)]. No statistically significant differences between groups were observed for any of the secondary outcomes, neither in subgroups, nor for the per-protocol population.

Conclusions

We did not observe any statistical significant effects of the IMMENSE intervention on the rate of emergency medical visits or any other secondary outcomes after 12 months in hospitalized older adults included in this study.

Trial registration

The trial was registered in clinicaltrials.gov on 28/06/2016, before enrolment started (NCT02816086).

The effect of a trAnSitional Pharmacist Intervention in geRiatric inpatients on hospital visits after dischargE (ASPIRE): Protocol for a randomized controlled trial

BACKGROUND

Unplanned rehospitalizations occur frequently in older patients. Drug-related problems constitute a major and largely preventable cause with inappropriate prescribing being a substantial culprit. Solutions are needed to reduce this risk by targeting pharmacotherapy both during and after hospital stay. Therefore, we aim to perform a randomized controlled trial in geriatric inpatients to investigate the impact of a multifaceted clinical pharmacy intervention on health-related outcomes.

METHODS/DESIGN

The study concerns a monocenter, non-blinded, randomized controlled trial that will take place at the acute geriatric wards of a large academic hospital. Patients being in a palliative stage with active therapy withdrawal or patients discharged to another ward within the same hospital or another hospital are excluded. In total, 828 patients will be randomized (1:1) to the usual care or intervention group. The multifaceted clinical pharmacy intervention comprises medication reconciliation at admission and discharge, medication review, patient/caregiver education, intensified communication with primary care providers and post-discharge follow-up, which also includes a telepharmacology service. The primary endpoint is defined as the time to an all-cause, unplanned hospital revisit within six months after discharge. Other health-related outcomes such as drug-related readmissions, quality of life and number of potentially inappropriate medications will be analyzed as secondary endpoints. Patient inclusion started in February 2021.

DISCUSSION

This study will provide useful insights regarding the impact of clinical pharmacy interventions on geriatric wards with the goal to optimize health-related outcomes such as hospital revisits.
