The impact of a medication review with follow-up service on hospital admissions in aged polypharmacy patients

Components of pharmacist-led medication reviews and their relationship to outcomes: a systematic review and narrative synthesis

INTRODUCTION

Pharmacist-led medication reviews are an established intervention to support patients prescribed multiple medicines or with complex medication regimes. For this systematic review, a medication review was defined as 'a consultation between a pharmacist and a patient to review the patient's total medicines use with a view to improve patient health outcomes and minimise medicines-related problems'. It is not known how varying approaches to medication reviews lead to different outcomes.

AIM

To explore the common themes associated with positive outcomes from pharmacist-led medication reviews.

METHOD

Randomised controlled trials of pharmacist-led medication reviews in adults aged 18 years and over were included. The search terms used in MEDLINE, EMBASE and Web of Science databases were "medication review", "pharmacist", "randomised controlled trial" and their synonyms, time filter 2015 to September 2023. Studies published before 2015 were identified from a previous systematic review. Risk of bias was assessed using the Cochrane risk of bias 2 tool. Descriptions of medication reviews' components, implementation and outcomes were narratively synthesised to draw out common themes. Results are presented in tables.

RESULTS

Sixty-eight papers describing 50 studies met the inclusion criteria. Common themes that emerged from synthesis include collaborative working which may help reduce medicines-related problems and the number of medicines prescribed; patient involvement in goal setting and action planning which may improve patients' ability to take medicines as prescribed and help them achieve their treatment goals; additional support and follow-up, which may lead to improved blood pressure, diabetes control, quality of life and a reduction of medicines-related problems.

CONCLUSION

This systematic review identified common themes and components, for example, goal setting, action planning, additional support and follow-up, that may influence outcomes of pharmacist-led medication reviews. Researchers, health professionals and commissioners could use these for a comprehensive evaluation of medication review implementation.

Harmonizing the definition of medication reviews for their collaborative implementation and documentation in electronic patient records: A Delphi consensus study

BACKGROUND

Medication review practices have evolved internationally in a direction in which not only physicians but also other healthcare professionals conduct medication reviews according to agreed practices. Collaborative practices have increasingly highlighted the need for electronic joint platforms where information on medication regimens and their implementation can be documented, kept updated, and shared.

OBJECTIVE

The aim of this study was to harmonize the definition of medication reviews and create a unified conceptual basis for their collaborative implementation and documentation in electronic patient records (definition appellation: collaborative medication review).

METHODS

The study was conducted using the Delphi consensus survey with three interprofessional expert panel rounds in September-December 2020. The consensus rate was set at 80%. Experts assessed the proposed definition of collaborative medication review based on an international and national inventory of medication review definitions. The expert panel (n = 41) involved 12 physicians, 13 pharmacists, 10 nurses, and six information management professionals. The range of response rates for the rounds was 63-88%.

RESULTS

The experts commented on which of the pre-selected items (n = 75) characterizing medication reviews should be included in the definition of collaborative medication review. The items were divided into the following five themes and 51 of them reached consensus: 1) Actions included in the collaborative medication review (n = 24/24), 2) Settings where the review should be conducted (n = 5/5), 3) Situations where the review should be considered as needed and carried out (n = 10/11), 4) Prioritization of top five benefits to be achieved by the review and 5) Prioritization of top five patient groups to whom the review should be targeted.

CONCLUSIONS

A strong interprofessional consensus was reached on the definition of collaborative medication review. The most challenging was to identify individual patient groups benefiting from the review.

[Exploration of professional and working conditions among community pharmacists in Gipuzkoa]

The purpose of this study is to explore the professional and working conditions of community pharmacists in the province of Gipuzkoa.The methodology employed involved: 1) A discussion with owner pharmacists and associate pharmacists, 2) A survey on satisfaction and work-life balance of pharmacists working in community pharmacies, and 3) Analysis of the reasons for cancelling membership of the association of pharmacists in the last 3 years. Data were analysed qualitatively and quantitatively.There was evidence of a range of issues including difficulty in recruiting associate pharmacists, unfavourable work-life balance, low job satisfaction and lack of professional development, poor business hours and other working conditions. Owner pharmacists reported a higher level of job satisfaction and work-life balance than associate pharmacists (p<0.001). However, both groups had a poor work-life balance. The issue of work-life balance is seen as being better in pharmacies with continuous business hours, as opposed to those with split (morning/afternoon) hours. Seventy percent (n=67) of pharmacists who cancelled their membership of the association over the last three years moved to another professional domain, particularly education and industry.In-depth deliberation is required into the professional and working situation of pharmacists working in community pharmacies, with a view to positing global strategies to improve job satisfaction and work-life balance.

Evaluation of an enhanced service for medication review with follow up in Swiss community pharmacies: Pre-post study protocol

BACKGROUND

In Switzerland, 20,000 people are hospitalized each year as result of drug related problems (DRPs). The sources of DRPs can be related to patients' behavior (i.e., wrong administration) or to health processes (i.e., drug-drug interaction). No community pharmacy (CP) service focus on DRPs related to patients' behavior is currently recognized or remunerated in Switzerland. A medication review with follow up (MRF) has been developed to evaluate prescription and non-prescription medication.

OBJECTIVE

To evaluate the impact of MRF service for the identification and management DRPs associated to patients' behavior and to describe pharmaceutical interventions carried out through MRF.

METHODS

A pre-post intervention study with a cluster design and one intervention group will be carried out in CPs in the canton of Vaud (Switzerland) for 15 months. Volunteer pharmacists will be trained on the identification and management of DRPs related to patients' behavior. After training, they will include randomly selected adults taking four or more chronic drugs prescribed for at least three months prior to recruitment. Then, they will conduct three pharmacist-patient face-to-face consultations at 6-month intervals. Tasks will be differentiated by pharmacy technician or pharmacist to triage expired medication or to manage DRPs in a structured manner, respectively. The primary outcome is the identification of DRPs associated to patients' behavior. Secondary outcomes are to assess patients' medication knowledge, number of expired medications, interventions carried out by pharmacists and pharmacists' satisfaction. The study will begin in April 2023 in 19 to 35 pharmacies that will recruit at least 162 patients. A sub analysis will be carried out for patients with 65 years old or over.

CONCLUSIONS

The MRF intervention features a training designed for an enhanced evaluation of patient's behavior towards their medication. The study will allow the assessment and management of DRPs in Swiss CPs with the support of the local health authorities and pharmacist association.

Clinical and Cost-Saving Effects of the Drug Utilization Review Modernization Project in Inpatient and Outpatient Settings in Korea

OBJECTIVES

Korea's national health insurance authority introduced a drug utilization review modernization pilot project in which health professionals provided follow-up services to monitor adverse drug events. We aimed to evaluate the effects of the project on clinical and economic outcomes.

METHODS

We conducted difference-in-differences analysis using National Health Insurance claims data from the Health Insurance Review and Assessment Service. We calculated the number of adverse drug events and allergic reactions as a clinical indicator and medical costs incurred to manage these events as an economic indicator. Absolute difference in each outcome measure was defined as the value after the project minus the value before the project. Difference-in-differences was defined as a difference in absolute differences between the intervention group and the control group.

RESULTS

Overall, difference-in-differences were -43 and -826 for the number of drug-related adverse events and allergic reactions and -$198,700 and $53,318 for medical costs in the inpatient and outpatient settings, respectively. For outpatients, the monthly number of adverse drug events and allergic reactions has grown higher for the control group than for the intervention group after implementation of the pilot project.

CONCLUSIONS

Implementation of the pilot project lowered the number of adverse drug events and allergic reactions in the inpatient and outpatient setting. The project also lowered medical costs incurred to manage these events in the inpatient setting only. Based on our findings, we recommend that the pilot project be expanded on a nationwide level at least in the inpatient setting.

Barriers to Medication Review Process Implementation—Cross-Sectional Study among Community Pharmacists in Jordan

The medication review process (MRP) is an extended, vital role of community pharmacists in improving health outcomes of medication use, yet it is neither systematically nor comprehensively provided bycommunity pharmacies in Jordan. This study aimed to identify the potential barriers hinderingMRP implementation bycommunity pharmacists in Jordan. A total of 550 community pharmacists electronically received a previously constructed and validated Arabic questionnaire explicitly developed to assess the current medication review practices and factors hindering the MRP, of whom 417 answered the questionnaire, giving a response rate of 75.8%. Among the investigated six categories’ seventeen barriers tothe implementation of the MRP, the highest rating was found for remuneration barriers (55.8%), followed by barriers related to regulations and patients, which scored 52.3% and 48.8%, respectively. Resource-related barriers were recognizedby 44.6% of participants, while qualifications and barriers related to physicians scored 42.9% and 41.8%, respectively. Although community pharmacists in Jordan are eager to extend their roles from traditional to more patient-centered ones, they encounter various barriers hinderingsuch development. Regulation adjustments accompanied by cost-effective remuneration and proper training are strong facilitators for community pharmacists to initiate the medication review service; make available the needed resources; and invest efforts, time, and money to operate it.

Clinical and Humanistic Outcomes of Community Pharmacy-Based Healthcare Interventions Regarding Medication Use in Older Adults: A Systematic Review and Meta-Analysis

This review and meta-analysis aimed to determine the clinical and humanistic outcomes of community pharmacy-based interventions on medication-related problems of older adults at the primary care level. We identified randomized controlled trials (RCTs) examining the impact of various community pharmacy-based interventions from five electronic databases (namely, MEDLINE (Ovid), EMBASE (Ovid), CINAHL, APA PSYInfo, and Scopus) from January 2010 to December 2020. Consequently, we assessed these interventions’ clinical and humanistic outcomes on older adults and compared them with non-intervention. We included 13 RCTs in the current review and completed a meta-analysis with six of them. The included studies had a total of 6173 older adults. Quantitative analysis showed that patient education was significantly associated with an increase in the discontinuation of sedative–hypnotics use (risk ratio 1.28; 95% CI (1.20, 1.36) I2 = 0%, p < 0.00001). Moreover, the qualitative analysis showed that medication reviews and education with follow-ups could improve various clinical outcomes, including reducing adverse drug events, reducing uncontrolled health outcomes, and improving appropriate medication use among the elderly population. However, medication review could not significantly reduce the number of older adults who fall (risk ratio 1.25; 95% CI (0.78, 1.99) I2 = 0%, p = 0.36) and require hospitalization (risk ratio 0.72; 95% CI (0.47, 1.12) I2 = 45%, p = 0.15). This study showed that community pharmacy-based interventions could help discontinue inappropriate prescription medications among older adults and could improve several clinical and humanistic outcomes. However, more effective community pharmacy-based interventions should be implemented, and more research is needed to provide further evidence for clinical and humanistic outcomes of such interventions on older adults.

Development and validation of explicit criteria to identify potentially inappropriate prescribing for adults with type 2 diabetes mellitus

BACKGROUND

Early detection and timely resolution of potentially inappropriate prescribing (PIP) prevents adverse outcomes and improves patient care. An explicit tool specifically designed to detect PIP among people with Type 2 Diabetes Mellitus (T2DM) has not been published.

OBJECTIVES

This study aims to develop and validate the Inappropriate Medication Prescribing Assessment Criteria for Type 2 Diabetes Mellitus (IMPACT2DM); an explicit tool that can be used to identify PIP for adults with T2DM.

METHODS

Current national and international guidelines for the management of T2DM and drug information software programs were used to generate potential items. The content of the IMPACT2DM was validated by 2 consecutive rounds of Delphi method. Physicians and clinical pharmacists experienced in providing care for people with diabetes and authors of selected diabetes guidelines were invited to participate in the Delphi panel. Consensus was assumed if 90% (first round) and 85% (second round) of expert panelists showed agreement to include or exclude an item.

RESULTS

A total of 95 potential items were generated from selected diabetes guidelines and drug information software programs. After the first Delphi round 27 items had ≥90% agreement and were included in the tool; 19 items were considered not PIP and were excluded from the tool. The second round contained 49 items; of these 43 were included and 6 were excluded from the tool. The final IMPACT2DM contains 70 items categorized by type of PIP and arranged in terms of medical conditions and medication classes. IMPACT2DM can be applied using information on medical charts and requires minimal or no clinical knowledge to assess quality of diabetes care and improve medication selection.

CONCLUSIONS

IMPACT2DM has been developed from current quality evidence and undergone content validation. It is the first explicit tool specifically designed to identify PIP for adults with T2DM.

Impact of Medication Reviews Delivered by Community Pharmacist to Elderly Patients on Polypharmacy: A Meta-analysis of Randomized Controlled Trials

OBJECTIVE

The aim of the study was to assess the impact of medication reviews delivered by community pharmacists to elderly patients on polypharmacy.

METHODS

A systematic literature search was performed in four bibliographic databases/search engine (PubMed, Embase, CENTRAL, and IPA) and three gray literature sources (OpenGrey, ClinicalTrials.gov, and Digital Access to Research Theses - Europe) from inception to January 2018. Randomized controlled trials were selected if they met the following criteria: (a) studied in patients 65 years or older who were taking four or more prescribed medications; (b) the "test" interventions were delivered by community pharmacists; and (c) measured one of these following outcomes: hospitalization, emergency department (ED) visit, quality of life, or adherence. Quality of the included studies was assessed using the Cochrane Effective Practice and Organization of Care Group risk of bias tool. Random-effects model meta-analyses were performed.

RESULTS

Of the 3634 articles screened, four studies with a total of 4633 participants were included. The intervention provided in all included studies was clinical medication review. Three studies were at low risk of bias, and the remaining study had unclear risk of bias. When compared with usual care, medication reviews provided by community pharmacist significantly reduced risk of ED visits (risk ratio = 0.68; 95% confidence interval = 0.48-0.96). There was also a tendency that pharmacist interventions decreased risk of hospitalizations (risk ratio = 0.88; 95% CI = 0.78-1.00), although no statistical significant.

CONCLUSIONS

The current evidence demonstrates that clinical medication reviews for older people with polypharmacy reduces the risk of ED visits. Medication reviews can be considered as another area where community pharmacists can contribute to improve patient safety.

Economic Evaluations of Interventions to Optimize Medication Use in Older Adults with Polypharmacy and Multimorbidity: A Systematic Review

Purpose

To conduct a systematic review of the economic impact of interventions intended at optimizing medication use in older adults with multimorbidity and polypharmacy.

Methods

We searched Ovid-Medline, Embase, CINAHL, Ageline, Cochrane, and Web of Science, for articles published between 2004 and 2020 that studied older adults with multimorbidity and polypharmacy. The intervention studied had to be aimed at optimizing medication use and present results on costs.

Results

Out of 3,871 studies identified by the search strategy, eleven studies were included. The interventions involved different provider types, with a majority described as a multidisciplinary team involving a pharmacist and a general practitioner, in the decision-making process. Interventions were generally associated with a reduction in medication expenditure. The benefits of the intervention in terms of clinical outcomes remain limited. Five studies were cost-benefit analyses, which had a net benefit that was either null or positive. Cost-utility and cost-effectiveness analyses resulted in incremental cost-effectiveness ratios that were generally within the willingness-to-pay thresholds of the countries in which the studies were conducted. However, the quality of the studies was generally low. Omission of key cost elements of economic evaluations, including intervention cost and payer perspective, limited interpretability.

Conclusion

Interventions to optimize medication use may provide benefits that outweigh their implementation costs, but the evidence remains limited. There is a need to identify and address barriers to the scaling-up of such interventions, starting with the current incentive structures for pharmacists, physicians, and patients.

Systematic review of pragmatic randomised control trials assessing the effectiveness of professional pharmacy services in community pharmacies

BACKGROUND

Implementation of Professional Pharmacy Services (PPSs) requires a demonstration of the service's impact (efficacy) and its effectiveness. Several systematic reviews and randomised controlled trials (RCT) have shown the efficacy of PPSs in patient's outcomes in community pharmacy. There is, however, a need to determine the level of evidence on the effectiveness of PPSs in daily practice by means of pragmatic trials. To identify and analyse pragmatic RCTs that measure the effectiveness of PPSs in clinical, economic and humanistic outcomes in the community pharmacy setting.

METHODS

A systematic search was undertaken in MEDLINE, EMBASE, the Cochrane Library and SCIELO. The search was performed on January 31, 2020. Papers were assessed against the following inclusion criteria (1) The intervention could be defined as a PPS; (2) Undertaken in a community pharmacy setting; (3) Was an original paper; (4) Reported quantitative measures of at least one health outcome indicator (ECHO model); (5) The design was considered as a pragmatic RCT, that is, it fulfilled 3 predefined attributes. External validity was analyzed with PRECIS- 2 tool.

RESULTS

The search strategy retrieved 1,587 papers. A total of 12 pragmatic RCTs assessing 5 different types of PPSs were included. Nine out of the 12 papers showed positive statistically significant differences in one or more of the primary outcomes (clinical, economic or humanistic) that could be associated with the following PPS: Smoking cessation, Dispensing/Adherence service, Independent prescribing and MTM. No paper reported on cost-effectiveness outcomes.

CONCLUSIONS

There is limited available evidence on the effectiveness of community-based PPS. Pragmatic RCTs to evaluate clinical, humanistic and economic outcomes of PPS are needed.

Medication review with follow-up for cardiovascular outcomes: a trial based cost-utility analysis

Aim: To assess the trial-based cost-effectiveness of medication review with follow-up compared with usual care in primary care. Materials & methods: A cluster randomized controlled trial included patients if they were independent older adults, receiving five or more prescriptions, with moderate or high cardiovascular risk. Costs were estimated from the public healthcare sector perspective, and health benefits were measured as quality-adjusted life years. Both of which were used to calculate the incremental cost-effectiveness ratio. Results: Twelve centers completed the study, six (146 patients) in the intervention group and six (145 patients) in the control group. The base-case analysis showed an incremental cost-effectiveness ratio of US$ (2019) 434.4/quality-adjusted life year (95% CI 64.20-996.03). Conclusion: The intervention was cost-effective in the public primary care setting.

Deprescribing for Community-Dwelling Older Adults: a Systematic Review and Meta-analysis

BACKGROUND

Polypharmacy and use of inappropriate medications have been linked to increased risk of falls, hospitalizations, cognitive impairment, and death. The primary objective of this review was to evaluate the effectiveness, comparative effectiveness, and harms of deprescribing interventions among community-dwelling older adults.

METHODS

We searched OVID MEDLINE Embase, CINAHL, and the Cochrane Library from 1990 through February 2019 for controlled clinical trials comparing any deprescribing intervention to usual care or another intervention. Primary outcomes were all-cause mortality, hospitalizations, health-related quality of life, and falls. The secondary outcome was use of potentially inappropriate medications (PIMs). Interventions were categorized as comprehensive medication review, educational initiatives, and computerized decision support. Data abstracted by one investigator were verified by another. We used the Cochrane criteria to rate risk of bias for each study and the GRADE system to determine certainty of evidence (COE) for primary outcomes.

RESULTS

Thirty-eight low and medium risk of bias clinical trials were included. Comprehensive medication review may have reduced all-cause mortality (OR 0.74, 95% CI: 0.58 to 0.95, I2 = 0, k = 12, low COE) but probably had little to no effect on falls, health-related quality of life, or hospitalizations (low to moderate COE). Nine of thirteen trials reported fewer PIMs in the intervention group. Educational interventions probably had little to no effect on all-cause mortality, hospitalizations, or health-related quality of life (low to moderate COE). The effect on falls was uncertain (very low COE). All 11 education trials that included PIMs reported fewer in the intervention than in the control groups. Two of 4 computerized decision support trials reported fewer PIMs in the intervention arms; none included any primary outcomes.

DISCUSSION

In community-dwelling people aged 65 years and older, medication deprescribing interventions may provide small reductions in mortality and use of potentially inappropriate medications.

Evaluating an implementation programme for medication review with follow-up in community pharmacy using a hybrid effectiveness study design: translating evidence into practice

OBJECTIVES

To evaluate an implementation programme of a community pharmacy medication review with follow-up (MRF) service using a hybrid effectiveness-implementation study design, and to compare the clinical and humanistic outcomes with those in a previously conducted cluster randomised controlled trial (cRCT).

SETTING

Community pharmacies in Spain.

PARTICIPANTS

135 community pharmacies and 222 pharmacists providing MRF to polymedicated patients aged 65 or over.

INTERVENTION

The intervention was an implementation programme for the MRF service. A national level group was established, mirrored with a provincial level group. A series of interventions were defined (1) to engage pharmacy owners with the implementation model and (2) to provide training to pharmacists consisting of clinical case studies, process of MRF, communication skills and data collection methods and (3) practice change facilitators.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcomes for the implementation programme were progress, reach, fidelity and integration. The secondary outcomes were number of medications, non-controlled health problems, emergency visits, hospitalisations and health-related quality of life, which were compared with a previous 6-month cluster RCT.

RESULTS

55% of pharmacies reached the implementation phase and 35.6% remained in the testing phase at 12 months. A reach of 89.3% (n=844) was achieved. Fidelity average score was 8.45 (min: 6.2, max: 9.3) out of 10. The integration mean score was 3.39 (SD: 0.72) out of 5. MRF service outcomes were similar to the cluster RCT study; however, the magnitude of the outcomes was delayed.

CONCLUSIONS

The implementation of pharmacy services is a complex multifactorial process, conditioned by numerous implementation factors. In the absence of remuneration, the implementation of the MRF service is a slow process, taking at least 12 months to complete.

The medication discrepancy detection service: A cost-effective multidisciplinary clinical approach

OBJECTIVE

To estimate the effectiveness of a Medication Discrepancy Detection Service (MDDS), a collaborative service between the community pharmacy and Primary Care.

DESIGN

Non-controlled before-and-after study.

SETTING

Bidasoa Integrated Healthcare Organisation, Gipuzkoa, Spain.

PARTICIPANTS

The service was provided by a multidisciplinary group of community pharmacists (CPs), general practitioners (GPs), and primary care pharmacists, to patients with discrepancies between their active medical charts and medicines that they were actually taking.

OUTCOMES

The primary outcomes were the number of medicines, the type of discrepancy, and GPs' decisions. Secondary outcomes were time spent by CPs, emergency department (ED) visits, hospital admissions, and costs.

RESULTS

The MDDS was provided to 143 patients, and GPs resolved discrepancies for 126 patients. CPs identified 259 discrepancies, among which the main one was patients not taking medicines listed on their active medical charts (66.7%, n=152). The main GPs' decision was to withdraw the treatment (54.8%, n=125), which meant that the number of medicines per patient was reduced by 0.92 (9.12±3.82 vs. 8.20±3.81; p<.0001). The number of ED visits and hospital admissions per patient were reduced by 0.10 (0.61±.13 vs 0.52±0.91; p=.405 and 0.17 (0.33±0.66 vs. 0.16±0.42; p=.007), respectively. The cost per patient was reduced by €444.9 (€1003.3±2165.3 vs. €558.4±1273.0; p=.018).

CONCLUSION

The MDDS resulted in a reduction in the number of medicines per patients and number of hospital admissions, and the service was associated with affordable, cost-effective ratios.

Interventions for improving medication-taking ability and adherence in older adults prescribed multiple medications

BACKGROUND

Older people taking multiple medications represent a large and growing proportion of the population. Managing multiple medications can be challenging, and this is especially the case for older people, who have higher rates of comorbidity and physical and cognitive impairment than younger adults. Good medication-taking ability and medication adherence are necessary to ensure safe and effective use of medications.

OBJECTIVES

To evaluate the effectiveness of interventions designed to improve medication-taking ability and/or medication adherence in older community-dwelling adults prescribed multiple long-term medications.

SEARCH METHODS

We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), PsycINFO, CINAHL Plus, and International Pharmaceutical Abstracts from inception until June 2019. We also searched grey literature, online trial registries, and reference lists of included studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs), quasi-RCTs, and cluster-RCTs. Eligible studies tested interventions aimed at improving medication-taking ability and/or medication adherence among people aged ≥ 65 years (or of mean/median age > 65 years), living in the community or being discharged from hospital back into the community, and taking four or more regular prescription medications (or with group mean/median of more than four medications). Interventions targeting carers of older people who met these criteria were also included.

DATA COLLECTION AND ANALYSIS

Two review authors independently reviewed abstracts and full texts of eligible studies, extracted data, and assessed risk of bias of included studies. We conducted meta-analyses when possible and used a random-effects model to yield summary estimates of effect, risk ratios (RRs) for dichotomous outcomes, and mean differences (MDs) or standardised mean differences (SMDs) for continuous outcomes, along with 95% confidence intervals (CIs). Narrative synthesis was performed when meta-analysis was not possible. We assessed overall certainty of evidence for each outcome using Grades of Recommendation, Assessment, Development and Evaluation (GRADE). Primary outcomes were medication-taking ability and medication adherence. Secondary outcomes included health-related quality of life (HRQoL), emergency department (ED)/hospital admissions, and mortality.

MAIN RESULTS

We identified 50 studies (14,269 participants) comprising 40 RCTs, six cluster-RCTs, and four quasi-RCTs. All included studies evaluated interventions versus usual care; six studies also reported a comparison between two interventions as part of a three-arm RCT design. Interventions were grouped on the basis of their educational and/or behavioural components: 14 involved educational components only, 7 used behavioural strategies only, and 29 provided mixed educational and behavioural interventions. Overall, our confidence in results regarding the effectiveness of interventions was low to very low due to a high degree of heterogeneity of included studies and high or unclear risk of bias across multiple domains in most studies. Five studies evaluated interventions for improving medication-taking ability, and 48 evaluated interventions for improving medication adherence (three studies evaluated both outcomes). No studies involved educational or behavioural interventions alone for improving medication-taking ability. Low-quality evidence from five studies, each using a different measure of medication-taking ability, meant that we were unable to determine the effects of mixed interventions on medication-taking ability. Low-quality evidence suggests that behavioural only interventions (RR 1.22, 95% CI 1.07 to 1.38; 4 studies) and mixed interventions (RR 1.22, 95% CI 1.08 to 1.37; 12 studies) may increase the proportions of people who are adherent compared with usual care. We could not include in the meta-analysis results from two studies involving mixed interventions: one had a positive effect on adherence, and the other had little or no effect. Very low-quality evidence means that we are uncertain of the effects of educational only interventions (5 studies) on the proportions of people who are adherent. Low-quality evidence suggests that educational only interventions (SMD 0.16, 95% CI -0.12 to 0.43; 5 studies) and mixed interventions (SMD 0.47, 95% CI -0.08 to 1.02; 7 studies) may have little or no impact on medication adherence assessed through continuous measures of adherence. We excluded 10 studies (4 educational only and 6 mixed interventions) from the meta-analysis including four studies with unclear or no available results. Very low-quality evidence means that we are uncertain of the effects of behavioural only interventions (3 studies) on medication adherence when assessed through continuous outcomes. Low-quality evidence suggests that mixed interventions may reduce the number of ED/hospital admissions (RR 0.67, 95% CI 0.50 to 0.90; 11 studies) compared with usual care, although results from six further studies that we were unable to include in meta-analyses indicate that the intervention may have a smaller, or even no, effect on these outcomes. Similarly, low-quality evidence suggests that mixed interventions may lead to little or no change in HRQoL (7 studies), and very low-quality evidence means that we are uncertain of the effects on mortality (RR 0.93, 95% CI 0.67 to 1.30; 7 studies). Moderate-quality evidence shows that educational interventions alone probably have little or no effect on HRQoL (6 studies) or on ED/hospital admissions (4 studies) when compared with usual care. Very low-quality evidence means that we are uncertain of the effects of behavioural interventions on HRQoL (1 study) or on ED/hospital admissions (2 studies). We identified no studies evaluating effects of educational or behavioural interventions alone on mortality. Six studies reported a comparison between two interventions; however due to the limited number of studies assessing the same types of interventions and comparisons, we are unable to draw firm conclusions for any outcomes.

AUTHORS' CONCLUSIONS

Behavioural only or mixed educational and behavioural interventions may improve the proportion of people who satisfactorily adhere to their prescribed medications, but we are uncertain of the effects of educational only interventions. No type of intervention was found to improve adherence when it was measured as a continuous variable, with educational only and mixed interventions having little or no impact and evidence of insufficient quality to determine the effects of behavioural only interventions. We were unable to determine the impact of interventions on medication-taking ability. The quality of evidence for these findings is low due to heterogeneity and methodological limitations of studies included in the review. Further well-designed RCTs are needed to investigate the effects of interventions for improving medication-taking ability and medication adherence in older adults prescribed multiple medications.

Non-dispensing pharmacists' actions and solutions of drug therapy problems among elderly polypharmacy patients in primary care

OBJECTIVE

To evaluate the process of clinical medication review for elderly patients with polypharmacy performed by non-dispensing pharmacists embedded in general practice. The aim was to identify the number and type of drug therapy problems and to assess how and to what extent drug therapy problems were actually solved.

METHOD

An observational cross-sectional study, conducted in nine general practices in the Netherlands between June 2014 and June 2015. On three pre-set dates, the non-dispensing pharmacists completed an online data form about the last 10 patients who completed all stages of clinical medication review. Outcomes were the type and number of drug therapy problems, the extent to which recommendations were implemented and the percentage of drug therapy problems that were eventually solved. Interventions were divided as either preventive (aimed at following prophylactic guidelines) or corrective (aimed at active patient problems).

RESULTS

In total, 1292 drug therapy problems were identified among 270 patients, with a median of 5 (interquartile range 3) drug therapy problems per patient, mainly related to overtreatment (24%) and undertreatment (21%). The non-dispensing pharmacists most frequently recommended to stop medication (32%). Overall, 83% of the proposed recommendations were implemented; 57% were preventive, and 35% were corrective interventions (8% could not be assessed). Almost two-third (64%) of the corrective interventions actually solved the drug therapy problem.

CONCLUSION

Non-dispensing pharmacists integrated in general practice identified a large number of drug therapy problems and successfully implemented a proportionally high number of recommendations that solved the majority of drug therapy problems.

Do randomised controlled trials relevant to pharmacy meet best practice standards for quality conduct and reporting? A systematic review

OBJECTIVES

Evidence-based pharmacy practice requires a dependable evidence base. Randomised controlled trials (RCTs) are the gold standard of high-quality primary research, and tools exist to assist researchers in conducting and reporting high-quality RCTs. This review aimed to explore whether RCTs relevant to pharmacy are conducted and reported in line with Cochrane risk of bias and CONSORT standards, respectively.

METHODS

A MEDLINE search identified potential papers. After screening of titles, abstracts and full texts, the 50 most recent papers were reviewed and assessment of bias according to Cochrane domains and compliance with CONSORT checklist items was recorded. Each domain of the Cochrane tool and CONSORT checklist item and each article were given a percentage score, reported as median and interquartile range (IQR). Correlation between quality of conduct, quality of reporting, continent of origin, and journal impact factor was conducted using the R² statistic. The median domain score for risk of bias by paper according to the Cochrane risk of bias tool was 53.0% (IQR 38.5-68.5), while the median compliance score by paper for the CONSORT checklist was 64.0% (IQR 36.0-94.0%).

KEY FINDINGS

The median Cochrane domain and median CONSORT item completion scores, respectively, were 50.0% (IQR 33.3-66.7%) and 59.5% (IQR 52.0-70.3%). The highest risk of bias was associated with allocation concealment and blinding, and the least well-reported items were randomisation details, sequence generation and allocation concealment. A positive relationship between conduct and reporting of RCTs was found (R²  = 0.75), while no correlation was found between quality of conduct or quality of reporting and journal impact factor, correlation coefficients (R²  = 0.06 and R²  = 0.05, respectively).

SUMMARY

This review identified that issues related to randomisation and blinding are often inadequately conducted or not comprehensively reported by researchers conducting pharmacy relevant RCTs, providing useful information for education and future research.

Effects of non-dispensing pharmacists integrated in general practice on medication-related hospitalisations

Aims

To evaluate the effect of non‐dispensing pharmacists (NDPs) integrated in general practice on medication‐related hospitalisations, drug burden index and costs in patients at high risk of medication problems (being 65 years or older and using 5 or more chronic medications).

Methods

This was a multicentre, nonrandomised, controlled intervention study with pre–post comparison (2013 vs June 2014 to May 2015) in 25 general practices in the Netherlands, comparing NDP‐led care (intervention) with 2 current pharmaceutical care models (usual care and usual care plus). In the intervention group, 10 specially trained NDPs were employed in general practices to take integral responsibility for the pharmaceutical care. They provided a broad range of medication therapy management services both on patient level (e.g. clinical medication review) and practice level (e.g. quality improvement projects). In the control groups, pharmaceutical care was provided as usual by general practitioners and community pharmacists, or as usual plus, when pharmacists were additionally trained in performing medication reviews.

Results

Overall, 822 medication‐related hospitalisations were identified among 11 281 high‐risk patients during the intervention period. After adjustment for clustering and potential confounders, the rate ratio of medication‐related hospitalisations in the intervention group compared to usual care was 0.68 (95% confidence interval: 0.57–0.82) and 1.05 (95% confidence interval: 0.73–1.52) compared to usual care plus. No differences in drug burden index or costs were found.

Conclusions

In general practices with an integrated NDP, the rate of medication‐related hospitalisations is lower compared to usual care. No differences with usual care plus were found.

Effects of a clinical medication review focused on personal goals, quality of life, and health problems in older persons with polypharmacy: A randomised controlled trial (DREAMeR-study)

BACKGROUND

Clinical medication reviews (CMRs) are increasingly performed in older persons with multimorbidity and polypharmacy to reduce drug-related problems (DRPs). However, there is limited evidence that a CMR can improve clinical outcomes. Little attention has been paid to patients' preferences and needs. The aim of this study was to investigate the effect of a patient-centred CMR, focused on personal goals, on health-related quality of life (HR-QoL), and on number of health problems.

METHODS AND FINDINGS

This study was a randomised controlled trial (RCT) performed in 35 community pharmacies and cooperating general practices in the Netherlands. Community-dwelling older persons (≥70 years) with polypharmacy (≥7 long-term medications) were randomly assigned to usual care or to receive a CMR. Randomisation was performed at the patient level per pharmacy using block randomisation. The primary outcomes were HR-QoL (assessed with EuroQol [EQ]-5D-5L and EQ-Visual Analogue Scale [VAS]) and number of health problems (such as pain or dizziness), after 3 and 6 months. Health problems were measured with a self-developed written questionnaire as the total number of health problems and number of health problems with a moderate to severe impact on daily life. Between April 2016 and February 2017, we recruited 629 participants (54% females, median age 79 years) and randomly assigned them to receive the intervention (n = 315) or usual care (n = 314). Over 6 months, in the intervention group, HR-QoL measured with EQ-VAS increased by 3.4 points (95% confidence interval [CI] 0.94 to 5.8; p = 0.006), and the number of health problems with impact on daily life decreased by 12% (difference at 6 months -0.34; 95% CI -0.62 to -0.044; p = 0.024) as compared with the control group. There was no significant difference between the intervention group and control group for HR-QoL measured with EQ-5D-5L (difference at 6 months = -0.0022; 95% CI -0.024 to 0.020; p = 0.85) or total number of health problems (difference at 6 months = -0.30; 95% CI -0.64 to 0.054; p = 0.099). The main study limitations include the risk of bias due to the lack of blinding and difficulties in demonstrating which part of this complex intervention (for example, goal setting, extra attention to patients, reducing health problems, drug changes) contributed to the effects that we observed.

CONCLUSIONS

In this study, we observed that a CMR focused on personal goals improved older patients' lives and wellbeing by increasing quality of life measured with EQ-VAS and decreasing the number of health problems with impact on daily life, although it did not significantly affect quality of life measured with the EQ-5D. Including the patient's personal goals and preferences in a medication review may help to establish these effects on outcomes that are relevant to older patients' lives.

Pharmacist-participated medication review in different practice settings: Service or intervention? An overview of systematic reviews

Introduction

Medication review (MR) is a pharmacy practice conducted in different settings that has a positive impact on patient health outcomes. In this context, systematic reviews on MR have restricted the assessment of this practice using criteria such as methodological quality, practice settings, and patient outcomes. Therefore, expanding research on this subject is necessary to facilitate the understanding of the effectiveness of MR and the comparison of its results.

Aim

To examine the panorama of systematic reviews on pharmacist-participated MR in different practice settings.

Methods

A literature search was undertaken in Biblioteca Virtual em Saúde (BVS), Embase, PubMed, Scopus, The Cochrane Library, and Web of Science databases through January 2018 using keywords for "medication review", "systematic review", and "pharmacist". Two independents investigators screened titles, abstracts, full texts; assessed methodological quality; and, extracted data from the included reviews.

Results

Seventeen systematic reviews were included, of which sixteen presented low to moderate methodological quality. Most of reviews were conducted in Europe (n = 7), included controlled primary studies (n = 16), elderly patients (n = 9), and long-term care facilities (n = 8). Seven reviews addressed MR as an intervention and thirteen reviews cited collaboration between physicians and pharmacists in the practice of MR. In addition, thirteen terminologies for MR were used and the main objective was to identify and solve drug-related problems and/or optimize the drug use (n = 11).

Conclusion

There is considerable heterogeneity in practice settings, population, definitions, terminologies, and approach of MR as well as poor description of patient care process in the systematic reviews. These facts may limit the comparison, summarization and understanding of the results of MR. Furthermore, the methodological quality of most systematic reviews was below ideal. Thus, international agreement on the MR process is necessary to assess, compare and optimize the quality of care provided.

Role and impact of pharmacists in Spain: a scoping review

Background The role of the pharmacist has evolved greatly over the last decades, expanding to patient-oriented activities, administrative tasks and public health functions. However, considerable differences emerge across regions. Aim of the review To gather evidence in order to describe and highlight the different characteristics of the pharmacists' role and the impact of their activities in Spain. Method A review of the existing literature was conducted. The literature search was undertaken in PubMed between 01/01/2006 and 15/08/2017. Results were screened and reviewed to extract previously established criteria such as author(s), publication year, language, study design, setting, pharmaceutical activity, patient care programs, targeted diseases and intervention description using DEPICT2 tool. Pharmaceutical intervention were classified into eight outcome measures and categorized by types of outcomes reported: descriptive or impact evaluation regarding the effect of the service (positive, neutral or negative). Results The search strategy resulted in 473 articles and 108 articles met the inclusion criteria. The most common design was observational (n = 76, 70%). Most articles were published after 2011 (75%), in English (69%). Studies were conducted in hospitals (60%) and community pharmacies (30%). Of the 24 pharmaceutical activities identified, medication review was the activity most frequently studied (n = 42), followed by patient education (n = 29), risk and prevention (n = 27) and medication reconciliation (n = 19). Only 39 articles (36%) had outcome measures with impact evaluation. Of the 223 impact outcome measures, 48% (107/223) had a positive effect. Conclusion This review shows the substantial scientific production focusing on pharmacy practice in Spain over the last years. The evidence reviewed reflects the pharmacist role at various professional settings, providing a wide variety of activities on diverse targeted diseases and patient care programs, in line with the increasing specialization of clinical pharmacists over the last years.

Development of a standardized chart review method to identify drug-related hospital admissions in older people

AIMS

We aimed to develop a standardized chart review method to identify drug-related hospital admissions (DRA) in older people caused by non-preventable adverse drug reactions and preventable medication errors including overuse, underuse and misuse of medications: the DRA adjudication guide.

METHODS

The DRA adjudication guide was developed based on design and test iterations with international and multidisciplinary input in four subsequent steps: literature review; evaluation of content validity using a Delphi consensus technique; a pilot test; and a reliability study.

RESULTS

The DRA adjudication guide provides definitions, examples and step-by-step instructions to measure DRA. A three-step standardized chart review method was elaborated including: (i) data abstraction; (ii) explicit screening with a newly developed trigger tool for DRA in older people; and (iii) consensus adjudication for causality by a pharmacist and a physician using the World Health Organization-Uppsala Monitoring Centre and Hallas criteria. A 15-member international Delphi panel reached consensus agreement on 26 triggers for DRA in older people. The DRA adjudication guide showed good feasibility of use and achieved moderate inter-rater reliability for the evaluation of 16 cases by four European adjudication pairs (71% agreement, κ = 0.41). Disagreements arose mainly for cases with potential underuse.

CONCLUSIONS

The DRA adjudication guide is the first standardized chart review method to identify DRA in older persons. Content validity, feasibility of use and inter-rater reliability were found to be satisfactory. The method can be used as an outcome measure for interventions targeted at improving quality and safety of medication use in older people.

Cost analysis and cost-benefit analysis of a medication review with follow-up service in aged polypharmacy patients

BACKGROUND

Drug related problems have a significant clinical and economic burden on patients and the healthcare system. Medication review with follow-up (MRF) is a professional pharmacy service aimed at improving patient's health outcomes through an optimization of the medication.

OBJECTIVE

To ascertain the economic impact of the MRF service provided in community pharmacies to aged polypharmacy patients comparing MRF with usual care, by undertaking a cost analysis and a cost-benefit analysis.

METHODS

The economic evaluation was based on a cluster randomized controlled trial. Patients in the intervention group (IG) received the MRF service and the comparison group (CG) received usual care. The analysis was conducted from the national health system (NHS) perspective over 6 months. Direct medical costs were included and expressed in euros at 2014 prices. Health benefits were estimated by assigning a monetary value to the quality-adjusted life years. One-way deterministic sensitivity analysis was undertaken in order to analyse the uncertainty.

RESULTS

The analysis included 1403 patients (IG: n = 688 vs CG: n = 715). The cost analysis showed that the MRF saved 97 € per patient in 6 months. Extrapolating data to 1 year and assuming a fee for service of 22 € per patient-month, the estimated savings were 273 € per patient-year. The cost-benefit ratio revealed that for every 1 € invested in MRF, a benefit of 3.3 € to 6.2 € was obtained.

CONCLUSION

The MRF provided health benefits to patients and substantial cost savings to the NHS. Investment in this service would represent an efficient use of healthcare resources.

Professional, structural and organisational interventions in primary care for reducing medication errors

BACKGROUND

Medication-related adverse events in primary care represent an important cause of hospital admissions and mortality. Adverse events could result from people experiencing adverse drug reactions (not usually preventable) or could be due to medication errors (usually preventable).

OBJECTIVES

To determine the effectiveness of professional, organisational and structural interventions compared to standard care to reduce preventable medication errors by primary healthcare professionals that lead to hospital admissions, emergency department visits, and mortality in adults.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, three other databases, and two trial registries on 4 October 2016, together with reference checking, citation searching and contact with study authors to identify additional studies. We also searched several sources of grey literature.

SELECTION CRITERIA

We included randomised trials in which healthcare professionals provided community-based medical services. We also included interventions in outpatient clinics attached to a hospital where people are seen by healthcare professionals but are not admitted to hospital. We only included interventions that aimed to reduce medication errors leading to hospital admissions, emergency department visits, or mortality. We included all participants, irrespective of age, who were prescribed medication by a primary healthcare professional.

DATA COLLECTION AND ANALYSIS

Three review authors independently extracted data. Each of the outcomes (hospital admissions, emergency department visits, and mortality), are reported in natural units (i.e. number of participants with an event per total number of participants at follow-up). We presented all outcomes as risk ratios (RRs) with 95% confidence intervals (CIs). We used the GRADE tool to assess the certainty of evidence.

MAIN RESULTS

We included 30 studies (169,969 participants) in the review addressing various interventions to prevent medication errors; four studies addressed professional interventions (8266 participants) and 26 studies described organisational interventions (161,703 participants). We did not find any studies addressing structural interventions. Professional interventions included the use of health information technology to identify people at risk of medication problems, computer-generated care suggested and actioned by a physician, electronic notification systems about dose changes, drug interventions and follow-up, and educational interventions on drug use aimed at physicians to improve drug prescriptions. Organisational interventions included medication reviews by pharmacists, nurses or physicians, clinician-led clinics, and home visits by clinicians.There is a great deal of diversity in types of professionals involved and where the studies occurred. However, most (61%) of the interventions were conducted by pharmacists or a combination of pharmacists and medical doctors. The studies took place in many different countries; 65% took place in either the USA or the UK. They all ranged from three months to 4.7 years of follow-up, they all took place in primary care settings such as general practice, outpatients' clinics, patients' homes and aged-care facilities. The participants in the studies were adults taking medications and the interventions were undertaken by healthcare professionals including pharmacists, nurses or physicians. There was also evidence of potential bias in some studies, with only 18 studies reporting adequate concealment of allocation and only 12 studies reporting appropriate protection from contamination, both of which may have influenced the overall effect estimate and the overall pooled estimate. Professional interventionsProfessional interventions probably make little or no difference to the number of hospital admissions (risk ratio (RR) 1.24, 95% confidence interval (CI) 0.79 to 1.96; 2 studies, 3889 participants; moderate-certainty evidence). Professional interventions make little or no difference to the number of participants admitted to hospital (adjusted RR 0.99, 95% CI 0.92 to 1.06; 1 study, 3661 participants; high-certainty evidence). Professional interventions may make little or no difference to the number of emergency department visits (adjusted RR 0.71, 95% CI 0.50 to 1.02; 2 studies, 1067 participants; low-certainty evidence). Professional interventions probably make little or no difference to mortality in the study population (adjusted RR 0.98, 95% CI 0.82 to 1.17; 1 study, 3538 participants; moderate-certainty evidence). Organisational interventionsOverall, it is uncertain whether organisational interventions reduce the number of hospital admissions (adjusted RR 0.85, 95% CI 0.71 to 1.03; 11 studies, 6203 participants; very low-certainty evidence). Overall, organisational interventions may make little difference to the total number of people admitted to hospital in favour of the intervention group compared with the control group (adjusted RR 0.92, 95% CI 0.86 to 0.99; 13 studies, 152,237 participants; low-certainty evidence. Overall, it is uncertain whether organisational interventions reduce the number of emergency department visits in favour of the intervention group compared with the control group (adjusted RR 0.75, 95% CI 0.49 to 1.15; 5 studies, 1819 participants; very low-certainty evidence. Overall, it is uncertain whether organisational interventions reduce mortality in favour of the intervention group (adjusted RR 0.94, 95% CI 0.85 to 1.03; 12 studies, 154,962 participants; very low-certainty evidence.

AUTHORS' CONCLUSIONS

Based on moderate- and low-certainty evidence, interventions in primary care for reducing preventable medication errors probably make little or no difference to the number of people admitted to hospital or the number of hospitalisations, emergency department visits, or mortality. The variation in heterogeneity in the pooled estimates means that our results should be treated cautiously as the interventions may not have worked consistently across all studies due to differences in how the interventions were provided, background practice, and culture or delivery of the interventions. Larger studies addressing both professional and organisational interventions are needed before evidence-based recommendations can be made. We did not identify any structural interventions and only four studies used professional interventions, and so more work needs to be done with these types of interventions. There is a need for high-quality studies describing the interventions in more detail and testing patient-related outcomes.

Tamoxifen Pharmacovigilance: Implications for Safe Use in the Future

OBJECTIVE

To survey the status of current tamoxifen pharmacovigilance documentation reflecting tamoxifen use in an academic outpatient multispecialty practice in older adults. This data will help provide information to develop improved pharmacovigilance for a growing cohort of older adult users. The data will be utilized by an interdisciplinary team developing new methods of identifying factors for individualized pharmacovigilance in older adults.

DESIGN

Retrospective chart review to gather descriptive and quantitative data on tamoxifen pharmacovigilance.

SETTING

Multi-specialty clinic.

PATIENTS

Ninety-three patients 60 years of age and older.

MAIN OUTCOME MEASURES

Quantitative report of tamoxifen monitoring as well as descriptive analysis of individual cases.

RESULTS

We found 19 cases of serious adverse events possibly related to tamoxifen (thrombi, uterine malignancies). There were 15 cases with no documentation of pharmacovigilance. All cases had incomplete pharmacovigilance documented. There were two cases of hypercalcemia. There was one case of tamoxifen discontinuation resulting from muscle pain and with chronic muscle pain complaints while receiving tamoxifen. We observed a correlation in older age or high comorbidity burden patients and adverse events patients.

CONCLUSION

Some studies direct the important pharmacovigilance toward prevention of thrombi, uterine malignancies, and hypercalcemia; however, it is not easy to identify recommendations for frequency or focus of monitoring to prevent adverse events for individual older adults based on existing recommendations. The data collected and presented in this study serve to heighten awareness of tamoxifen pharmacovigilance and as a starting point for the application of machine learning techniques and modeling to identify high-risk patients and individualized pharmacovigilance recommendations.

The impact of drug related problems on health-related quality of life among hypertensive patients in Jordan

BACKGROUND

Hypertension is a major cause of cardiovascular diseases with a high prevalence in Jordan. No previous studies have been carried out to determine the effect of the presence of drug-related problems (DRPs) on the health-related quality of life (HRQOL) among hypertensive patients.

OBJECTIVES

The purpose of this study was to identify the influence of different types of DRPs on the HRQOL of hypertensive patients.

METHODS

A total of 200 hypertensive patients were recruited in this cross-sectional correlation study that was conducted across the cardiac outpatient clinic at Jordan University Hospital. Ethical approval was obtained and patients were recruited using convenience sampling technique. During the study period, patients' data was used to evaluate their quality of life using RAND-12 scale and to identify DRPs utilizing a systematic evidence based approach.

RESULTS

200 hypertensive patients (mean age 59.7 years (SD=10.2)) were recruited in this study. Patients showed a poor quality of life on both the physical and mental domains of the RAND-12 scale. The average number of DRPs was 5.1 (SD=2.3). Multiple linear regression analysis showed that among DRPs categories, non-adherence to medications, non-adherence to non-pharmacological therapies and inadequate knowledge about medications were among the main predictors of the poor physical domain of the RAND-12 (Beta= -0.149, -0.226 and -0.230 respectively, p-value < 0.05 for all). On the other hand, only non-adherence to medication and non-adherence to non-pharmacological therapies were significantly associated with poor mental domain of the RAND-12 (Beta= -0.208 and -0.191 respectively, p-value < 0.05 for both).

CONCLUSION

Prevalence of DRPs among hypertensive patients is a concern that needs attention. These DRPs were associated with poor HRQOL on both the physical and mental domain of the RAND-12 scale. The pharmaceutical care service delivered by pharmacists is needed to identify, prevent and resolve DRPs, which may improve patients HRQOL.

Occupational Therapy and Management of Multiple Chronic Conditions in the Context of Health Care Reform

One in four individuals living in the United States has multiple chronic conditions (MCCs), and the already high prevalence of MCCs continues to grow. This population has high rates of health care utilization yet poor outcomes, leading to elevated concerns about fragmented, low-quality care provided within the current health care system. Several national initiatives endeavor to improve care for the population with MCCs, and occupational therapy is uniquely positioned to contribute to these efforts for more efficient, effective, client-centered management of care. By integrating findings from the literature with current policy and practice, we aim to highlight the potential role for occupational therapy in managing MCCs within the evolving health care system.

Medication management activities performed by informal caregivers of older adults

BACKGROUND

Medication management is commonly performed by informal caregivers, yet they are often unprepared and ill-equipped to manage complex medication regimens for their older adult care recipients. In order to develop interventions that will enhance the caregiver's ability to safely and confidently manage medications, it is critical to first understand caregiver challenges and unmet needs related to medication management.

OBJECTIVES

To explore how informal caregivers manage medications for their older adult care recipients by identifying the activities involved in medication management and the tools or strategies used to facilitate these activities.

METHODS

Four focus groups with caregivers of older adults were conducted with 5-9 caregivers per group. Participants were asked to describe the medication management activities performed and the tools or strategies used to facilitate these activities. Focus groups were recorded, transcribed verbatim, and analyzed for themes using an inductive approach.

RESULTS

Caregivers were commonly involved in 2 types of activities: direct activities requiring physical handling of medications such as obtaining medications, preparing pill boxes, and assisting with medication administration; and indirect activities that were more complex and required more of a cognitive effort by the caregiver, such as organizing and tracking medications, gathering information, and making treatment decisions. They utilized a variety of tools and strategies to support these medication management activities; however, these approaches often needed to be modified or personalized to meet the specific needs of their caregiving situation.

CONCLUSIONS

Informal caregivers play a vital role in ensuring safe and appropriate medication use by older adults. Medication management is complex and involves many activities that are supported through the use of a variety of tools and strategies that have been adapted and individualized to each specific caregiving scenario. Caregivers should be an important component of interventions that aim to improve medication use among older adults.

The impact of a medication review with follow-up service on hospital admissions in aged polypharmacy patients

AIMS

The aims were to assess the impact of a medication review with follow-up (MRF) service provided in community pharmacy to aged polypharmacy patients on the number of medication-related hospital admissions and to estimate the effect on hospital costs.

METHODS

This was a sub-analysis of a cluster randomized controlled trials carried out in 178 community pharmacies in Spain. Pharmacies in the intervention group (IG) provided a comprehensive medication review during 6 months. Pharmacists in the comparison group (CG) delivered usual care. For the purposes of this sub-analysis, an expert panel of three internal medicine specialists screened the hospitalizations occurring during the main study, in order to identify medication-related hospitalizations. Inter-rater reliability was measured using Fleiss's kappa. Hospital costs were calculated using diagnosis related groups.

RESULTS

One thousand four hundred and three patients were included in the main study and they had 83 hospitalizations. Forty-two hospitalizations (50.6%) were medicine-related, with a substantial level of agreement among the experts (kappa = 0.65, 95% CI 0.52, 0.78, P < 0.01). The number of medication-related hospitalizations was significantly lower in patients receiving MRF (IG 11, GC 31, P = 0.042). The probability of being hospitalized was 3.7 times higher in the CG (odds ratio 3.7, 95% CI 1.2, 11.3, P = 0.021). Costs for a medicine-related hospitalization were €6672. Medication-related hospitalization costs were lower for patients receiving MRF [IG: €94 (SD 917); CG: €301 (SD 2102); 95% CI 35.9, 378.0, P = 0.018].

CONCLUSION

MRF provided by community pharmacists might be an effective strategy to balance the assurance of the benefit from medications and the avoidance of medication-related hospitalizations in aged patients using polypharmacy.
