Appropriateness of prescribing among elderly patients in a Dutch residential home: observational study of outcomes after a pharmacist-led medication review

Factors Influencing Medical Prescribers' Acceptance of Pharmacists' Recommendations in Non-hospitalized Older Adults: A Systematic Review and Meta-Analysis

OBJECTIVES

To investigate the rate of, and factors affecting, acceptance of pharmacists' recommendations by medical prescribers following medication reviews conducted in non-hospitalized older adults.

DESIGN

A systematic review and meta-analysis with meta-regression.

SETTING AND PARTICIPANTS

Older adults (mean aged ≥55 years) residing in the community or in aged care facilities (ie, non-hospitalized) who had received an individualized medication review by a pharmacist.

METHODS

We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched 3 databases (MEDLINE, Embase, and Web of Science) from 2000 until May 2024, and included studies that reported the acceptance rates of pharmacists' recommendations by prescribers, either by recommendation type (eg, initiation, cessation, dose change) or the reason for the recommendation (eg, drug-related problem identified). JBI tools were used to assess the methodological quality, and a meta-analysis with meta-regression was performed.

RESULTS

There were 21 studies included in the review: 13 studies in the community setting, and 8 in aged care facilities. The acceptance rates of the pharmacists' recommendations ranged from 42% to 93%, and the implementation rates ranged from 27% to 88%. The setting where the pharmacist conducted the review was found to be a significant determinant in the acceptance of recommendations in the meta-regression model (P = .021), with the highest acceptance and implementation rates reported when pharmacists were integrated into general medical practices (79%; 95% CI, 52%-97%).

CONCLUSIONS AND IMPLICATIONS

The acceptance of pharmacists' recommendations following the conduct of medication reviews was highly variable. Multiple factors appear to influence acceptance rates, particularly the setting where the pharmacist conducted the review and the level of collaboration between the pharmacist and prescriber. Future research should explore targeted strategies to improve collaboration and communication between pharmacists and prescribers, such as the integration of pharmacists into general medical practices and aged care facilities.

Association between Cognitive Impairment Severity and Polypharmacy in Older Patients with Atrial Fibrillation: A Retrospective Study Using Inpatient Data from a Specialised Geriatric Hospital

This study aimed to investigate the association between cognitive impairment and polypharmacy in patients with atrial fibrillation prone to cognitive decline, and to elucidate if the Dementia Assessment Sheet for Community-based Integrated Care System 21-Items (DASC-21) severity classification indicates drug adjustment. This retrospective cohort study used the DASC-21 and Diagnosis Procedure Combination data at a specialised geriatric hospital with patients hospitalised between April 2019 and March 2022. The association between cognitive severity evaluated using the DASC-21 and polypharmacy was investigated using a multivariate logistic regression model. Data of 1191 inpatients (44.3% aged ≥85 years, 49.0% male) were analysed. Compared with severe cognitive impairment, mild (odds ratio [OR]: 3.33, 95% confidence interval [CI]: 1.29-8.57) and moderate (OR: 2.46, 95% CI: 1.06-5.72) impairments were associated with concurrent use of ≥6 medications. Antithrombotics were related to polypharmacy. The ORs did not change with 6, 8, or 10 medications (2.11 [95% CI: 1.51-2.95, p < 0.001], 2.42 [95% CI: 1.79-3.27, p < 0.001], and 2.01 [95% CI: 1.46-2.77, p < 0.001], respectively). DASC-21 severity was associated with polypharmacy in patients with atrial fibrillation, with a trend toward decreased polypharmacy from moderate to severe. The DASC-21 may serve as an indicator for drug adjustment in clinical practice.

The OptimaMed intervention to reduce medication burden in nursing home residents with severe dementia: results from a pragmatic, controlled study

BACKGROUND

Nursing home (NH) residents with severe dementia use many medications, sometimes inappropriately within a comfort care approach. Medications should be regularly reviewed and eventually deprescribed. This pragmatic, controlled trial assessed the effect of an interprofessional knowledge exchange (KE) intervention to decrease medication load and the use of medications of questionable benefit among these residents.

METHODS

A 6-month intervention was performed in 4 NHs in the Quebec City area, while 3 NHs, with comparable admissions criteria, served as controls. Published lists of "mostly", "sometimes" or "exceptionally" appropriate medications, tailored for NH residents with severe dementia, were used. The intervention included 1) information for participants' families about medication use in severe dementia; 2) a 90-min KE session for NH nurses, pharmacists, and physicians; 3) medication reviews by NH pharmacists using the lists; 4) discussions on recommended changes with nurses and physicians. Participants' levels of agitation and pain were evaluated using validated scales at baseline and the end of follow-up.

RESULTS

Seven (7) NHs and 123 participants were included for study. The mean number of regular medications per participant decreased from 7.1 to 6.6 in the intervention, and from 7.7 to 5.9 in the control NHs (p-value for the difference in differences test: < 0.05). Levels of agitation decreased by 8.3% in the intervention, and by 1.4% in the control NHs (p = 0.026); pain levels decreased by 12.6% in the intervention and increased by 7% in the control NHs (p = 0.049). Proportions of participants receiving regular medications deemed only exceptionally appropriate decreased from 19 to 17% (p = 0.43) in the intervention and from 28 to 21% (p = 0.007) in the control NHs (p = 0.22). The mean numbers of regular daily antipsychotics per participant fell from 0.64 to 0.58 in the intervention and from 0.39 to 0.30 in the control NHs (p = 0.27).

CONCLUSIONS

This interprofessional intervention to reduce inappropriate medication use in NH residents with severe dementia decreased medication load in both intervention and control NHs, without important concomitant increase in agitation, but mixed effects on pain levels. Practice changes and heterogeneity within these 7 NHs, and a ceiling effect in medication optimization likely interfered with the intervention.

TRIAL REGISTRATION

The study is registered at ClinicalTrials.gov: # NCT05155748 (first registration 03-10-2017).

Evaluation approaches, tools and aspects of implementation used in pharmacist interventions in residential aged care facilities: A scoping review

BACKGROUND

The medication expertise of pharmacists is widely acknowledged and there is ongoing interest in their potential role to reduce medication-related harm amongst residents living in residential aged care facilities (RACFs). An increased understanding of how these interventions are evaluated could support adoption of these interventions in the real world.

OBJECTIVE

To systematically explore the application of evaluation approaches, evaluation tools and aspects of implementation (implementation factors i.e. barriers and facilitators, and assessing implementation fidelity) used in pharmacist intervention in RACF peer-reviewed literature.

METHODS

A search strategy was applied to MEDLINE, CINAHL, Cochrane Library and Web of Science databases for publications between 1 January 2000 and 27 August 2020 based on defined inclusion and exclusion criteria. Articles that reported on evaluated pharmacist interventions impacting residents in RACFs or which outlined study participant perspectives in relation to these interventions were included.

RESULTS

2003 published articles were identified, out of which 56 articles met the inclusion criteria. Fifty-three articles reported on outcome evaluations. Four articles used evaluation guidance with 1 article explicitly guided by an evaluation framework. Relationships, trust and respect between pharmacists and RACF health care team members were one of the most reported factors influencing intervention success. None of the 56 articles used a theory or model, assessed implementation fidelity or employed a logic model.

CONCLUSIONS

To date there appears to be sparse utilisation of available evaluation approaches, evaluation tools and implementation aspects in pharmacist intervention in RACF peer-reviewed literature. By embracing these evaluation approaches, evaluation tools and aspects of implementation, pharmacy practice researchers have an opportunity to contribute to evaluation research in RACFs and beyond.

Clinical and cost effectiveness of a multi-professional medication reviews in care homes (CAREMED)†

Objectives

With 70% of care home residents experiencing a medication error every day in the UK, better multi-professional working between medical practitioners, pharmacists and care homes was recommended. The aim of this study was to determine the effectiveness (falls reduction) and cost-effectiveness, of a multi-professional medication review (MPMR) service in care homes for older people.

Method

A total of care homes in the East of England were cluster randomised to ‘usual care’ or two multi-professional (General practitioner, clinical pharmacist and care homes staff) medication reviews during the 12-month trial period. Target recruitment was 900 residents with 10% assumed loss to follow-up. Co-primary outcome measures were number of falls and potentially inappropriate prescribing assessed by the Screening Tool of Older Persons Prescriptions.

Key findings

A total of 826 care home residents were recruited with 324 lost to follow-up for at least one primary outcome measure. The mean number of falls per resident per annum was 3.3 for intervention and 3.0 for control (P = 0.947). Each resident was found to be prescribed 0.69 (intervention) and 0.85 (control) potentially inappropriate medicines after 12 months (P = 0.046). No significant difference identified in emergency hospital admissions or deaths. Estimated unadjusted incremental mean cost per resident was £374.26 higher in the intervention group.

Conclusions

In line with other medication review based interventions in care homes, two MPMRs improved medication appropriateness but failed to demonstrate improvements in clinical outcomes. From a health system perspective costs where estimated to increase overall and therefore a different model of medicines management is required.

Systematic review and narrative synthesis of pharmacist provided medicines optimisation services in care homes for older people to inform the development of a generic training or accreditation process

OBJECTIVES

To develop a training programme to enable pharmacists with prescribing rights to assume responsibility for the provision of pharmaceutical care within care homes, a systematic review and narrative synthesis was undertaken to identify reported approaches to training pharmacists and use this literature to identify potential knowledge requirements.

METHODS

A PROSPERO-registered systematic review was performed using key search terms for care homes, pharmacist, education, training and pharmaceutical care. Papers reporting primary research focussed on care of the older person within the care home setting were included. No restrictions were placed on methodology. Two researchers independently reviewed titles, abstracts and papers. Agreement on inclusion was reached through consensus. Data on titles, training and activities undertaken were extracted and knowledge requirements identified. Findings were synthesised and reported narratively.

KEY FINDINGS

Fifty-nine papers were included, most of which were uncontrolled service evaluations. Four papers reported an accreditation process for the pharmacist. Thirteen papers reported providing tools or specific training on a single topic to pharmacists. The main clinical and therapeutic areas of activity (requiring codified knowledge) were dementia, pain, antipsychotic and cardiovascular medication. Provision of pharmaceutical care, effective multidisciplinary working and care home staff training represented the main areas of practical knowledge.

CONCLUSIONS

Information regarding training and accreditation processes for care home pharmacists is limited. This study provides insight into potential codified and practical knowledge requirements for pharmacists assuming responsibility for the provision of pharmaceutical care within care homes. Further work involving stakeholders is required to identify the cultural knowledge requirements and to develop a training and accreditation process.

Reducing the Burden of Complex Medication Regimens: SImplification of Medications Prescribed to Long-tErm care Residents (SIMPLER) Cluster Randomized Controlled Trial

OBJECTIVE

To assess the application of a structured process to consolidate the number of medication administration times for residents of aged care facilities.

DESIGN

A nonblinded, matched-pair, cluster randomized controlled trial.

SETTING AND PARTICIPANTS

Permanent residents who were English-speaking and taking at least 1 regular medication, recruited from 8 South Australian residential aged care facilities (RACFs).

METHODS

The intervention involved a clinical pharmacist applying a validated 5-step tool to identify opportunities to reduce medication complexity (eg, by administering medications at the same time or through use of longer-acting or combination formulations). Residents in the comparison group received routine care. The primary outcome at 4-month follow-up was the number of administration times per day for medications charted regularly. Resident satisfaction and quality of life were secondary outcomes. Harms included falls, medication incidents, hospitalizations, and mortality. The association between the intervention and primary outcome was estimated using linear mixed models.

RESULTS

Overall, 99 residents participated in the intervention arm and 143 in the comparison arm. At baseline, the mean resident age was 86 years, 74% were female, and medications were taken an average of 4 times daily. Medication simplification was possible for 62 (65%) residents in the intervention arm, with 57 (62%) of 92 simplification recommendations implemented at follow-up. The mean number of administration times at follow-up was reduced in the intervention arm in comparison to usual care (-0.36, 95% confidence interval -0.63 to -0.09, P = .01). No significant changes in secondary outcomes or harms were observed.

CONCLUSIONS AND IMPLICATIONS

One-off application of a structured tool to reduce regimen complexity is a low-risk intervention to reduce the burden of medication administration in RACFs and may enable staff to shift time to other resident care activities.

Effectiveness of medication review on the number of drug-related problems in patients visiting the outpatient cardiology clinic: A randomized controlled trial

AIMS

To assess the effectiveness of medication review on the number of drug-related problems (DRPs) in outpatient cardiology patients.

METHODS

In this randomized controlled trial, a computer-assisted and pharmacist-led medication review with patient involvement (questionnaire and telephone call with pharmacist) was conducted in intervention patients prior to their visit to the cardiologist. The control group received usual care. Adult outpatient cardiology patients without support concerning the administration of medication, without a medication review in the past 6 months and who gave permission to access their electronic medication record were included. The primary outcome measure was the number of DRPs 1 month after the visit. Secondary outcome measures concerned the type of DRP and the type of medication involved in the DRPs.

RESULTS

In total, 75 patients (mean [standard deviation, SD] age 66.0 [12.5] years, 41% female) were included. Intervention (n = 90) and control group (n = 85) were comparable at baseline. The mean (SD) number of drugs used per patient was 7.9 (3.9). After 1 month, the mean (SD) number of DRPs was 0.3 (0.7) and 0.8 (1.0) and the median (range) number of DRPs was 0 (0-4) and 0 (0-4) in the intervention group and control group, respectively (P < .001). In the intervention group, 74% of the DRPs identified at T0 were solved at T1 vs 14% in the control group.

CONCLUSION

This randomized controlled trial suggests that a pharmacist-led medication review in patients with a scheduled visit to the outpatient cardiology clinic decreases the number of DRPs.

Pharmacist services in nursing homes: A systematic review and meta-analysis

AIMS

Pharmacists have been contributing to the care of residents in nursing homes and play a significant role in ensuring quality use of medicine. However, the changing role of pharmacist in nursing homes and their impact on residents is relatively unknown.

METHODS

Six electronic databases were searched from inception until November 2018 for articles published in English examining the services offered by pharmacists in nursing homes. Studies were included if it examined the impact of interventions by pharmacists to improve the quality use of medicine in nursing homes.

RESULTS

Fifty-two studies (30 376 residents) were included in the current review. Thirteen studies were randomised controlled studies, while the remainder were either pre-post, retrospective or case-control studies where pharmacists provided services such as clinical medication review in collaboration with other healthcare professionals as well as staff education. Pooled analysis found that pharmacist-led services reduced the mean number of falls (-0.50; 95% confidence interval: -0.79 to -0.21) among residents in nursing homes. Mixed results were noted on the impact of pharmacists' services on mortality, hospitalisation and admission rates among residents. The potential financial savings of such services have not been formally evaluated by any studies thus far. The strength of evidence was moderate for the outcomes of mortality and number of fallers.

CONCLUSION

Pharmacists contribute substantially to patient care in nursing homes, ensuring quality use of medication, resulting in reduced fall rates. Further studies with rigorous design are needed to measure the impact of pharmacist services on the economic benefits and other patient health outcomes.

Comparing Three Methods for Reducing Psychotropic Use in Older Demented Spanish Care Home Residents

BACKGROUND/OBJECTIVE

In nursing homes across the world, and particularly in Spain, there are concerns that psychotropic medications are being overused. For older Spanish nursing home residents who had dementia, we sought to evaluate the association between applying interventions designed to reduce inappropriate psychotropic medication use and subsequent psychotropic use.

DESIGN

Retrospective, propensity score-matched, controlled, patient-level observational analysis.

SETTING

A total of 45 nursing homes in Spain.

PARTICIPANTS

A total of 1653 nursing home residents, aged 70 to 99 years, who had dementia and were prescribed an antipsychotic, anxiolytic, or antidepressant medication, 606 of whom received an intervention; the remainder served as propensity score-matched controls.

INTERVENTION

Team Rounds, Screening Tool of Older Persons' Prescriptions (STOPP)/Screening Tool to Alert Doctors to Right Treatment (START) criteria, or a Patient Decision Aid.

MEASUREMENTS

At 2 and 4 weeks following intervention: change from baseline drug class-specific milligram-equivalent daily dose (MEDD); at 2 weeks: patient falls and restraint use.

RESULTS

Within each intervention/drug-class cohort, intervention patients and matched controls had similar baseline demographic characteristics, Charlson scores, lengths of admission, and drug class-specific MEDDs. Compared to controls, patients exposed to Team Rounds experienced a 23.3% (95% confidence interval [CI] = 13.9%-32.8%) reduction in antipsychotic and a 23.1% (95% CI = 18.3%-28.0%) reduction in anxiolytic MEDDs; those exposed to Patient Decision Aids had a 24.8% (95% CI = 15.6%-33.9%) reduction in antipsychotic and a 31.8% (95% CI = 25.5%-38.2%) reduction in anxiolytic MEDDs; and those exposed to STOPP/START application had a 27.7% (95% CI = 22.4%-33.0%) reduction in antipsychotic and a 39.5% (95% CI = 35.5%-43.5%) reduction in anxiolytic MEDDs. Intervention-associated antidepressant MEDD reductions were statistically significant but less dramatic. Interventions were associated with higher rates of medication discontinuation, but not higher rates of deaths, patient falls, or physical restraints.

CONCLUSION

We found strong evidence that the interventions we studied were associated with reduced psychotropic use without commensurate harms, suggesting that such interventions should be incorporated into Spanish nursing home care models. Public reporting of psychotropic medication use in Spanish care homes may encourage care homes to regularly monitor psychotropic medication use and implement such instruments.

Impact of pharmacist-led home medicines review services on drug-related problems among the elderly population: a systematic review

OBJECTIVES

To address and elucidate the impact of pharmacist-led home medicines review (HMR) services on identifying drug-related problems (DRPs) among the elderly population in home care settings.

METHODS

A comprehensive systematic search was performed using electronic scientific databases such as PubMed, Scopus, Embase, and Web of Science for studies published between January 1, 2008 and December 31, 2018, pertaining to HMR services by pharmacists for identifying DRPs.

RESULTS

In total, 4,292 studies were retrieved from the searches, of which 24 were excluded as duplicates. Titles and abstracts were screened for the remaining 4,268 studies, of which 4,239 were excluded due to the extraneous nature of the titles and/or abstracts. Subsequently, 29 full-text articles were assessed, and 19 were removed for lacking the outcome of interest and/or not satisfying the study’s inclusion criteria. Finally, 10 studies were included in the review; however, publication bias was not assessed, which is a limitation of this study. In all studies, pharmacists identified a highly significant amount of DRPs through HMR services. The most common types of DRPs were potential drug-drug interactions, serious adverse drug reactions, need for an additional drug, inappropriate medication use, non-adherence, untreated indications, excessive doses, and usage of expired medications.

CONCLUSIONS

HMR is a novel extended role played by pharmacists. The efficiency of such programs in identifying and resolving DRPs could minimize patients’ health-related costs and burden, thereby enhancing the quality of life and well-being among the elderly.

Detection of potentially inappropriate prescribing in older patients with the GheOP³S-tool: completeness and clinical relevance

OBJECTIVES

The Ghent Older People's Prescriptions community Pharmacy Screening (GheOP³S-) tool was recently developed as an explicit screening method to detect Potentially Inappropriate Prescribing (PIP) in the community pharmacy. We aimed to validate the GheOP³S-tool as an effective screening method for PIP.

METHODS

All patients admitted to the acute geriatric ward of the Sint-Vincentius hospital (Belgium) were consecutively screened for inclusion (≥70 years,≥5 drugs chronically). PIP prevalence was evaluated by applying the GheOP³S-tool on the complete medication history. For each PIP-item, clinical relevance of the detected item, relevance of proposed alternative and subsequent acceptance by the treating geriatrician and a general practitioner were evaluated. Additionally, contribution to the current admission and preventability was assessed by the geriatrician. The completeness of a PIP-screening with the GheOP³S-tool was evaluated through comparison with the adapted Medication Appropriateness Index (aMAI).

RESULTS

We detected 250 GheOP³S-items in 57 of 60 included patients (95%) (median: four PIP-items per patient; IQR: 3-5). Both the geriatrician and the general practitioners scored the clinical relevance of the detected items 'serious' or 'significant' in over 70% of cases. Proposed alternative treatment plans were accepted for 79% of the PIP-items (n = 198). The aMAI detected 536 items, of which 145 were also detected by the GheOP³S-tool. A total of 119 PIP-items were additionally detected by the GheOP³S-tool.

CONCLUSION

The clinical relevance of the PIP-items detected with the GheOP³S-tool is high, likewise the acceptance rate of proposed alternatives.

DREAMeR: Drug use Reconsidered in the Elderly using goal Attainment scales during Medication Review; study protocol of a randomised controlled trial

Background

Clinical medication reviews (CMR) are increasingly performed in older patients with polypharmacy. Studies have shown positive effects of CMR on process- and intermediate outcomes, like drug-related problems (DRPs). Little effect has been shown on clinical outcomes, like hospital admissions or health-related quality of life (HR-QoL). In particular, HR-QoL is related to the individual health-related goals and complaints of patients. The aim of this study is to investigate the effects of a CMR focused on personal goals on HR-QoL and health-related complaints in older patients with polypharmacy.

Methods

A randomised controlled trial will be performed in 35 Dutch community pharmacies aiming to include 630 patients aged 70 years and older using seven or more chronic drugs. Patients will be randomly assigned to control or intervention group by block-randomisation per pharmacy. Patients in the intervention group receive a CMR focused on patients’ preferences, personal goals and health-related complaints. With every goal a goal attainment scale (GAS) will be proposed. Primary outcome measures are HR-QoL, measured with the EQ-5D-5L and EQ-VAS and the number of health-related complaints per patient measured with a written questionnaire, during a follow-up period of six months. Secondary outcomes are healthcare utilisation, number and type of drug changes, number and type of health-related goals, scores on GAS and number and type of DRPs and interventions.

Discussion

This study is expected to add evidence on the effects of a CMR on HR-QoL and health-related complaints in older patients with polypharmacy. New in this study is the use of personal goals measured with GAS and health-related complaints as patient-related outcome measures.

Impact of pharmacist identification of medication-related problems in a nontraditional long-term care pharmacy

OBJECTIVES

To characterize the most common medication-related problems and interventions and to evaluate the acceptance rates of pharmacist identification of medication-related problems through percent acceptance rates of interventions in a nontraditional long-term care pharmacy.

METHODS

A retrospective chart review of long-term care pharmacy patients 18 years of age or older was used to evaluate pharmacist interventions from January 2014 to August 2016. Data collection included the date and type of intervention, patient demographic information (age, sex), drug class involved, physician provider type (primary care or specialist), intervention outcome, and resolution type. Accepted and rejected interventions were reviewed and classified based on Hepler and Strand's 8 medication-related problems: untreated indications, improper drug selection, subtherapeutic dosage, failure to receive medication, overdosage, adverse drug reactions, drug interactions, and medication use without indication. Data were analyzed with the use of descriptive statistics.

RESULTS

Four hundred seventeen interventions were documented over 18 months, approximately 13 interventions per month. Prescribers accepted 47% of interventions and rejected 29%. The remaining 24% of interventions did not have a response from the prescriber. Of the medication-related problems, "untreated indication" and "overdosage" were the most commonly intervened with and accepted interventions. Regarding drug class, pharmacists made the most interventions regarding immunizations (41%), diabetes medications (11%), cholesterol medications (10%), and hypertension medications (7%).

CONCLUSION

Pharmacists are improving the care of patients living in small group homes through various types of recommendations regarding complex disease states, such as diabetes, hyperlipidemia, and hypertension, further complicated by mental illness. With almost one-half of all recommendations accepted by prescribers, pharmacists consistently provided recommendations to improve care.

Impact of medication reviews on inappropriate prescribing in aged care

BACKGROUND

Inappropriate prescribing (IP) is prevalent among elderly people in aged care facilities. Little has been published on the effect of pharmacists performing residential medication management reviews (RMMRs) in aged care on the appropriateness of prescribing. RMMRs represents a key strategy for achieving quality use of medicines, by assisting residents in aged care facilities and their carers to better manage their medicines. However, the structure of RMMR has moved from annual to every two years for each resident.

OBJECTIVES

The primary objective of this study was to investigate the impact of pharmacists performing RMMRs on medication use appropriateness, as measured by the Medication Appropriateness Index (MAI).

METHODS

Retrospective analysis of RMMRs pertaining to 223 aged care residents aged ≥65 years in Sydney, Australia. The MAI was applied on two RMMR cohorts; newer cohort (n = 111, 2015) i.e. following the recent changes to the RMMR funding and older cohort (n = 112, 2012) at baseline, after pharmacists' recommendations (assuming all pharmacists' recommendations were accepted by the General Practitioner [GP]), and after the actual uptake of pharmacists' recommendations by the GP. Differences in inappropriate prescribing were measured using the Wilcoxon sign rank test.

RESULTS

Overall, all patients in the study (n = 223) had at least one inappropriate rating at baseline (median MAI score of 26 for the old cohort and 27 for the newer cohort). The median cumulative MAI scores were significantly lower after the RMMRs by pharmacists (15.5 and 20 for the old and new cohort respectively, p < .001) and following the uptake of recommendations by the GP, indicating an increased appropriateness of drug regimen after the medication review (20 and 22 for the old and new cohort respectively, p < .001).

CONCLUSION

This study shows that pharmacist-led medication reviews are effective in reducing inappropriate prescribing among aged care residents, as demonstrated by the reduction in MAI scores. Future studies should focus on the impact of such a decrease on patient outcomes.

Development and evaluation of an algorithm-based tool for Medication Management in nursing homes: the AMBER study protocol

BACKGROUND

Residents of nursing homes are susceptible to risks from medication. Medication Reviews (MR) can increase clinical outcomes and the quality of medication therapy. Limited resources and barriers between healthcare practitioners are potential obstructions to performing MR in nursing homes. Focusing on frequent and relevant problems can support pharmacists in the provision of pharmaceutical care services. This study aims to develop and evaluate an algorithm-based tool that facilitates the provision of Medication Management in clinical practice.

METHODS AND ANALYSIS

This study is subdivided into three phases. In phase I, semistructured interviews with healthcare practitioners and patients will be performed, and a mixed methods approach will be chosen. Qualitative content analysis and the rating of the aspects concerning the frequency and relevance of problems in the medication process in nursing homes will be performed. In phase II, a systematic review of the current literature on problems and interventions will be conducted. The findings will be narratively presented. The results of both phases will be combined to develop an algorithm for MRs. For further refinement of the aspects detected, a Delphi survey will be conducted. In conclusion, a tool for clinical practice will be created. In phase III, the tool will be tested on MRs in nursing homes. In addition, effectiveness, acceptance, feasibility and reproducibility will be assessed. The primary outcome of phase III will be the reduction of drug-related problems (DRPs), which will be detected using the tool. The secondary outcomes will be the proportion of DRPs, the acceptance of pharmaceutical recommendations and the expenditure of time using the tool and inter-rater reliability.

ETHICS AND DISSEMINATION

This study intervention is approved by the local Ethics Committee. The findings of the study will be presented at national and international scientific conferences and will be published in peer-reviewed journals.

A cooperation project between hospital pharmacists and general practitioners about drug interactions in clinical practice

Objectives

(1) To evaluate drug-drug interactions (DDIs) in general practitioners' (GPs) prescriptions; (2) to implement a cooperation project between pharmacists and GPs to improve DDI management and patient care.

Methods

In 2013, pharmacists from the Community Drug Assistance ASL TO1 launched a cooperation project involving 48 GPs. As a first step, GPs were asked to select, from a list, drug associations for which they recommended analysis of occurrence in their prescriptions. The pharmacists (1) analysed GPs' prescriptions dated 2012-2014, according to the list of DDIs selected (n= 9); (2) evaluated solutions for DDI management, using the Micromedex DDI checker database and literature analysis; they then (3) disseminated DDI-related information to GPs through training meetings and (4) assessed the efficacy of these actions through a questionnaire submitted to the GPs in 2013.

Results

(1) Prescriptions analysis: a reduction in the number of DDIs was observed (-14% in 2013 vs 2012, -9% in 2014 vs 2012); in some cases these reductions were statistically significant (calcium carbonate + proton pump inhibitors (PPIs) -50%, p<0.0041, amoxicillin+lansoprazole -42%, p<0.0088). (2) Questionnaire: this was completed by 75% of GPs. The literature analysis was considered interesting by 94% of GPs; solutions were adopted by 89% of GPs and 34% of GPs affirmed that clinical improvements after application of the measures were observed in their patients, even if they could not provide quantitative data for this outcome.

Conclusion

The cooperation project between pharmacists and GPs was effective because it established a professional exchange between the two health professionals. The pharmacist gave support to GPs, which benefited the patients, who gained clinical improvements and improved satisfaction with their medical care, as declared by the GPs in answers to the questionnaire.

Pharmacist Intervention Program at Different Rent Levels of Geriatric Healthcare

As a pharmacy service giving pharmaceutical care at different levels of health care for elderly people, we needed a standardization procedure for recording and evaluating pharmacists' interventions. Our objective was to homogenize pharmacist interventions; to know physicians' acceptance of our recommendations, as well as the most prevalent drug related problems (DRP); and the impact of the pharmacists' interventions. To achieve this goal we conducted a one year prospective study at two levels of health care: 176 nursing homes (EAR) (8828 patients) and 2 long-term and subacute care hospitals (HSS) (268 beds). Pharmacists' interventions were recorded using the American Society of Health-System Pharmacists classification as the basis. Frequency of the different DRP and the level of response and acceptance on the part of physicians was determined. The Medication Appropriateness Index (MAI) was used to evaluate the impact of the interventions on the prescription quality. Patients' mean age was 84.2 (EAR) and 80.7 (HSS), and in both cases, polypharmacy ≥ 9 drugs was around 63-69%. There were 4073 interventions done in EAR and 2560 in HSS. Level of response: 44% (EAR), 79% (HSS); degree of acceptance of the recommendations: 84% (EAR), 72% (HSS). Most frequent DRP: inappropriate dose, length of therapy, omissions, and financial impact. Drugs for the nervous system are those with the most DRP. MAI values/medication improved from 4.4 to 2.7 (EAR) and 3.8 to 1.7 (HSS). A normalized way of managing pharmacists' interventions for different health care levels has been established. We are on the way to increasing collaborative work with physicians and we know which DRPs are most prevalent.

Prevalence, risk factors and health outcomes associated with polypharmacy among urban community-dwelling older adults in multi-ethnic Malaysia

BACKGROUND

Polypharmacy has been associated with increased morbidity and mortality in the older population.

OBJECTIVES

The aim of this study was to determine the prevalence, risk factors and health outcomes associated with polypharmacy in a cohort of urban community-dwelling older adults receiving chronic medications in Malaysia.

METHODS

This was a baseline study in the Malaysian Elders Longitudinal Research cohort. The inclusion criteria were individuals aged ≥55years and taking at least one medication chronically (≥3 months). Participants were interviewed using a structured questionnaire during home visits where medications taken were reviewed. Health outcomes assessed were frequency of falls, functional disability, potential inappropriate medication use (PIMs), potential drug-drug interactions (PDDIs), healthcare utilisation and quality of life (QoL). Risk factors and health outcomes associated with polypharmacy (≥5 medications including dietary supplements) were determined using multivariate regression models.

RESULTS

A total of 1256 participants were included with a median (interquartile range) age of 69(63-74) years. The prevalence of polypharmacy was 45.9% while supplement users made up 56.9% of the cohort. The risk factors associated with increasing medication use were increasing age, Indian ethnicity, male, having a higher number of comorbidities specifically those diagnosed with cardiovascular, endocrine and gastrointestinal disorders, as well as supplement use. Health outcomes significantly associated with polypharmacy were PIMS, PDDIs and increased healthcare utilisation.

CONCLUSION

A significant proportion of older adults on chronic medications were exposed to polypharmacy and use of dietary supplements contributed significantly to this. Medication reviews are warranted to reduce significant polypharmacy related issues in the older population.

Supporting clinical rules engine in the adjustment of medication (SCREAM): protocol of a multicentre, prospective, randomised study

BACKGROUND

In the nursing home population, it is estimated that 1 in every 3 patients is polymedicated and given their considerable frailty, these patients are especially prone to adverse drug reactions. Clinical pharmacist-led medication reviews are considered successful interventions to improve medication safety in the inpatient setting. Due to the limited available evidence concerning the benefits of medication reviews performed in the nursing home setting, we propose a study aiming to demonstrate a positive effect that a clinical decision support system, as a health care intervention, may have on the target population. The primary objective of this study is to reduce the number of patients with at least one event when using the clinical decision support system compared to the regular care. These events consist of hospital referrals, delirium, falls, and/or deaths.

METHOD/DESIGN

This study is a multicentre, prospective, randomised study with a cluster group design. The randomisation will be per main nursing home physician and stratified per ward (somatic and psychogeriatric). In the intervention group the clinical decision support system will be used to screen medication list, laboratory values and medical history in order to obtain potential clinical relevant remarks. The remarks will be sent to the main physician and feedback will be provided whether the advice was followed or not. In the control group regular care will be applied.

DISCUSSION

We strongly believe that by using a clinical decision support system, medication reviews are performed in a standardised way which leads to comparable results between patients. In addition, using a clinical decision support system eliminates the time factor to perform medication reviews as the major problems related to medication, laboratory values, indications and/or established patient characteristics will be directly available. In this way, and in order to make the medication review process complete, consultation within healthcare professionals and/or the patient itself will be time effective and the medication surveillance could be performed around the clock.

Impact of joint consultation by a clinical pharmacist and a clinical geriatrician to improve inappropriate prescribing for elderly patients

Objective

Appropriate prescribing is a key quality element in medication safety. It is unclear if therapeutic interventions resulting from medication review lead to clinically relevant improvements. The effect of medication review on prescribing appropriateness was evaluated in the setting of an outpatient consultation team, consisting of a clinical pharmacist and a clinical geriatrician, in a large non-academic teaching hospital in the Netherlands.

Method

A group of 49 elderly patients with polypharmacy was included after referral by their general practitioner for drug related problems. After a regular assessment by a clinical geriatrician and medication record review by a clinical pharmacist, a treatment plan was implemented based on the recommended interventions. The main outcome measure was the change in the Medication Appropriateness Index (MAI) before and 3 months after primary consultation.

Results

Overall 82% of the recommended interventions of the pharmacist were implemented by the geriatrician of which 63% persisted up to the last visit. Per patient an average of 6.6 interventions were carried out. The interventions showed a reduction of the MAI per patient of 50%. The number of drugs per patient was reduced from 12.1 to 11.0. The number of medications listed on the Beers list decreased from 2.3 to 1.5 and the number of drugs listed on the Hospital Admissions Related to Medication (HARM) Trigger list decreased from 2.1 to 1.5.

Conclusions

Interventions from a multidisciplinary outpatient consultation team were effective in improving appropriate prescribing in elderly outpatients with polypharmacy.

Residential Aged Care Medication Review to Improve the Quality of Medication Use: A Systematic Review

BACKGROUND

Aging is often associated with various underlying comorbidities that warrant the use of multiple medications. Various interventions, including medication reviews, to optimize pharmacotherapy in older people residing in aged care facilities have been described and evaluated. Previous systematic reviews support the positive impact of various medication-related interventions but are not conclusive because of several factors.

OBJECTIVES

The current study aimed to assess the impact of medication reviews in aged care facilities, with additional focus on the types of medication reviews, using randomized controlled trials (RCTs) and observational studies.

METHODS

A systematic searching of English articles that examined the medication reviews conducted in aged care facilities was performed using the following databases: PubMed, CINAHL, IPA, TRiP, and the Cochrane Library, with the last update in December 2015. Extraction of articles and quality assessment of included articles were performed independently by 2 authors. Data on interventions and outcomes were extracted from the included studies. The SIGN checklist for observational studies and the Cochrane Collaboration's tool for assessing risk of bias in RCTs were applied. Outcomes assessed were related to medications, reviews, and adverse events.

RESULTS

Because of the heterogeneity of the measurements, it was deemed inappropriate to conduct a meta-analysis and thus a narrative approach was employed. Twenty-two studies (10 observational studies and 12 controlled trials) were included from 1141 evaluated references. Of the 12 trials, 8 studies reported findings of pharmacist-led medication reviews and 4 reported findings of multidisciplinary team-based reviews. The medication reviews performed in the included trials were prescription reviews (n = 8) and clinical medication reviews (n = 4). In the case of the observational studies, the majority of the studies (8/12 studies) reported findings of pharmacist-led medication reviews, and only 2 studies reported findings of multidisciplinary team-based reviews. Similarly, 6 studies employed prescription reviews, whereas 4 studies employed clinical medication reviews. The majority of the recommendations put forward by the pharmacist or a multidisciplinary team were accepted by physicians. The number of prescribed medications, inappropriate medications, and adverse outcomes (eg, number of deaths, frequency of hospitalizations) were reduced in the intervention group.

CONCLUSION

Medication reviews conducted by pharmacists, either working independently or with other health care professionals, appear to improve the quality of medication use in aged care settings. However, robust conclusions cannot be drawn because of significant heterogeneity in measurements and potential risk for biases.

The potential for deprescribing in care home residents with Type 2 diabetes

Background Type 2 diabetes is a common diagnosis in care home residents that is associated with potentially inappropriate prescribing and thus risk of additional suffering. Previous studies found that diabetes medicines can be safely withdrawn in care home residents, encouraging further investigation of the potential for deprescribing amongst these patients. Objectives Describe comorbidities and medicine use in care home residents with Type 2 diabetes; identify number of potentially inappropriate medicines prescribed for these residents using a medicines optimisation tool; assess clinical applicability of the tool. Setting Thirty care homes for older people, East Anglia, UK. Method Data on diagnoses and medicines were extracted from medical records of 826 residents. Potentially inappropriate medicines were identified using the tool 'Optimising Safe and Appropriate Medicines Use'. Twenty percent of results were validated by a care home physician. Main outcome measure Number of potentially inappropriate medicines. Results The 106 residents with Type 2 diabetes had more comorbidities and prescriptions than those without. Over 90 % of residents with Type 2 diabetes had at least one potentially inappropriate medication. The most common was absence of valid indication. The physician unreservedly endorsed 39 % of the suggested deprescribing, and would consider discontinuing all but one of the remaining medicines following access to additional information. Conclusion UK care home residents with Type 2 diabetes had an increased burden of comorbidities and prescriptions. The majority of these patients were prescribed potentially inappropriate medicines. Validation by a care home physician supported the clinical applicability of the medicines optimisation tool.

Design of the POINT study: Pharmacotherapy Optimisation through Integration of a Non-dispensing pharmacist in a primary care Team (POINT)

Background

In the Netherlands, 5.6 % of acute hospital admissions are medication-related. Almost half of these admissions are potentially preventable. Reviewing medication in patients at risk in primary care might prevent these hospital admissions. At present, implementation of medication reviews in primary care is suboptimal: pharmacists lack access to patient information, pharmacists are short of clinical knowledge and skills, and working processes of pharmacists (focus on dispensing) and general practitioners (focus on clinical practice) match poorly. Integration of the pharmacist in the primary health care team might improve pharmaceutical care outcomes.

The aim of this study is to evaluate the effect of integration of a non-dispensing pharmacist in general practice on the safety of pharmacotherapy in the Netherlands.

Methods

The POINT study is a non-randomised controlled intervention study with pre-post comparison in an integrated primary care setting. We compare three different models of pharmaceutical care provision in primary care: 1) a non-dispensing pharmacist as an integral member of a primary care team, 2) a pharmacist in a community pharmacy with a predefined training in performing medication reviews and 3) a pharmacist in a community pharmacy (care as usual). In all models, GPs remain accountable for individual medication prescription. In the first model, ten non-dispensing clinical pharmacists are posted in ten primary care practices (including 5 – 10 000 patients each) for a period of 15 months. These non-dispensing pharmacists perform patient consultations, including medication reviews, and share responsibility for the pharmaceutical care provided in the practice. The two other groups consist of ten primary care practices with collaborating pharmacists. The main outcome measurement is the number of medication-related hospital admissions during follow-up. Secondary outcome measurements are potential medication errors, drug burden index and costs. Parallel to this study, a qualitative study is conducted to evaluate the feasibility of introducing a NDP in general practice.

Discussion

As the POINT study is a large-scale intervention study, it should provide evidence as to whether integration of a non-dispensing clinical pharmacist in primary care will result in safer pharmacotherapy. The qualitative study also generates knowledge on the optimal implementation of this model in primary care. Results are expected in 2016.

To what extent is clinical and laboratory information used to perform medication reviews in the nursing home setting? the CLEAR study

BACKGROUND

The aim of this study was to evaluate to what extent laboratory data, actual medication, medical history, and/or drug indication influence the quality of medication reviews for nursing home patients.

METHODS

Forty-six health care professionals from different fields were requested to perform medication reviews for three different cases. Per case, the amount of information provided varied in three subsequent stages: stage 1, medication list only; stage 2, adding laboratory data and reason for hospital admission; and stage 3, adding medical history/drug indication. Following a slightly modified Delphi method, a multidisciplinary team performed the medication review for each case and stage. The results of these medication reviews were used as reference reviews (gold standard). The remarks from the participants were scored, according to their potential clinical impact, from relevant to harmful on a scale of 3 to -1. A total score per case and stage was calculated and expressed as a percentage of the total score from the expert panel for the same case and stage.

RESULTS

The overall mean percentage over all cases, stages, and groups was 37.0% when compared with the reference reviews. For one of the cases, the average score decreased significantly from 40.0% in stage 1, to 30.9% in stage 2, and 27.9% in stage 3; no significant differences between stages was found for the other cases.

CONCLUSION

The low performance, against the gold standard, of medication reviews found in the present study highlights that information is incorrectly used or wrongly interpreted, irrespective of the available information. Performing medication reviews without using the available information in an optimal way can have potential implications for patient safety.

Structured Medication Review to Improve Pharmacotherapy in People with Intellectual Disability and Behavioural Problems

BACKGROUND

Polypharmacy and chronic drug use are common in people with intellectual disability and behavioural problems, although evidence of effectiveness and safety in this population is lacking. This study examined the effects of a structured medication review and aimed to improve pharmacotherapy in inpatients with intellectual disability.

METHODS

In a treatment facility for people with mild to borderline intellectual disability and severe behavioural problems, a structured medication review was performed. Prevalence and type of drug-related problems (DRPs) and of the recommended and executed actions were calculated.

RESULTS

In a total of 55 patients with intellectual disability and behavioural problems, 284 medications were prescribed, in which a DRP was seen in 106 (34%). No indication/unclear indication was the most prevalent DRP (70). Almost 60% of the recommended actions were also executed.

CONCLUSIONS

This high prevalence of DRPs is worrying. The structured medication review is a valuable instrument to optimize pharmacotherapy and to support psychiatrists in adequate prescribing of both psychotropic and somatic drugs.

Conceptualizing and measuring potentially inappropriate drug therapy

WHAT IS KNOWN AND OBJECTIVE

Elderly people are the principal consumers of prescription drugs. The more the medication used by the patient, the greater the likelihood there is of the patient being subjected to potentially inappropriate drug therapy (PIDT). PIDT has been measured in the literature with both implicit and explicit tools. The purpose of this review was to assess the use of tools to detect PIDT in various studies and to determine which terms are used to refer to PIDT in practice.

METHODS

A systematic review was conducted according to the following steps: the first was identification. In this step, studies were selected from different combinations of the descriptors 'aged', 'elderly', 'inappropriate prescribing' and 'drug utilization' in three different languages, using the Embase, Medline, Scielo, Scopus and Web of Science databases. Second, the papers that satisfied the inclusion criteria for data extraction were carefully examined by three evaluators to determine the tools used and terms that referred to PIDT.

RESULTS AND DISCUSSION

From the combinations of keywords, 8610 articles were found. At the end of the selection process, 119 of the articles complied with the specified criteria. The degree of agreement among evaluators was moderate for the study titles (κ1  = 0·479) and substantial for abstracts (κ2  = 0·647). With respect to the PIDT evaluation criteria used by the studies, 27·7% used two criteria. Of the 27 evaluation criteria identified, the Beers criteria were used by 82·3% of the studies. More than 50 different terms to identify PIDT were found in the literature.

WHAT IS NEW AND CONCLUSION

This review is the first study to conceptualize and discuss terms that refer to PIDT. At present, there is no consensus regarding terms used to refer to PIDT, with over 50 different terms currently in use. This review shows an increase in the number of articles aimed at evaluating PIDT using implicit and explicit tools.

Development of an Aggregated System for Classifying Causes of Drug-Related Problems

Background: More than 20 different types of classification systems for drug-related problems (DRPs) and their causes have been developed. Classification is necessary to describe and assess clinical, organizational, and economic impacts of DRPs through documentation of collected data. However, many researchers have judged classification systems incomplete when describing their data, and have modified them or developed their own. This variability between systems has made study comparisons difficult. Objectives: To perform a category-by-category comparison of the content of selected DRP classification systems to construct an aggregated cause-of-DRP classification system containing the content of all systems. Method: DRP classification systems were identified after a literature review, with 7 chosen based on their use in varied health care settings, geographical diversity, frequency of use, and method of development. These systems were critically analyzed, and the content of each category was compared and aggregated where appropriate. A hierarchy of categories was constructed to include all content from all systems. Any modifications that previous studies may have made to the 7 systems were also cross-referenced to ensure that no concepts were missing from the newly aggregated system. Clinical examples to optimize application, and instructions for when or when not to use categories, were developed. Interrater agreement for classification of the causes of DRPs from 10 medication reviews was performed between 3 clinical pharmacists and the authors’ gold standard. Results: We found variation in developmental methods, category descriptions, number and types of categories, and validation methods between the 7 selected systems, together with intermingling of categories identified as causes of DRPs with DRPs themselves. A hierarchical classification system was constructed consisting of 9 cause-of-DRP categories, 33 subcategories, and 58 sub-subcategories, for which interrater agreements were 82.5%, 74.6%, and 58.8%, respectively. Conclusion: An aggregated classification system was constructed through a unique and transparent developmental process that may provide the most comprehensive description of causes of DRPs to date. This may facilitate teaching of pharmaceutical care, comparisons of clinical practice, and measurement of the effectiveness of pharmaceutical care interventions.

Health care consumers' perspectives on pharmacist integration into private general practitioner clinics in Malaysia: a qualitative study

BACKGROUND

Pharmacists are considered medication experts but are underutilized and exist mainly at the periphery of the Malaysian primary health care team. Private general practitioners (GPs) in Malaysia are granted rights under the Poison Act 1952 to prescribe and dispense medications at their primary care clinics. As most consumers obtain their medications from their GPs, community pharmacists' involvement in ensuring safe use of medicines is limited. The integration of a pharmacist into private GP clinics has the potential to contribute to quality use of medicines. This study aims to explore health care consumers' views on the integration of pharmacists within private GP clinics in Malaysia.

METHODS

A purposive sample of health care consumers in Selangor and Kuala Lumpur, Malaysia, were invited to participate in focus groups and semi-structured interviews. Sessions were audio recorded and transcribed verbatim and thematically analyzed using NVivo 10.

RESULTS

A total of 24 health care consumers participated in two focus groups and six semi-structured interviews. Four major themes were identified: 1) pharmacists' role viewed mainly as supplying medications, 2) readiness to accept pharmacists in private GP clinics, 3) willingness to pay for pharmacy services, and 4) concerns about GPs' resistance to pharmacist integration. Consumers felt that a pharmacist integrated into a private GP clinic could offer potential benefits such as to provide trustworthy information on the use and potential side effects of medications and screening for medication misadventure. The potential increase in costs passed on to consumers and GPs' reluctance were perceived as barriers to integration.

CONCLUSION

This study provides insights into consumers' perspectives on the roles of pharmacists within private GP clinics in Malaysia. Consumers generally supported pharmacist integration into private primary health care clinics. However, for pharmacists to expand their capacity in providing integrated and collaborative primary care services to consumers, barriers to pharmacist integration need to be addressed.

Potentially inappropriate prescribing in older primary care patients

OBJECTIVES

The aim of the study was to determine the rate of Potentially Inappropriate Medicines (PIM) and Potential Prescription Omissions (PPO) according to Screening Tool of Older Person's potentially inappropriate Prescriptions/Screening Tool to Alert doctors to the Right Treatment (STOPP/START) criteria.

STUDY DESIGN

A cross-sectional survey in community pharmacy.

METHOD

A prospective cross-sectional study was performed, during March-May 2012, in five community pharmacies. Patients aged ≥65 years, who collected one or more prescribed medications, were asked to participate in the study, and an interview was scheduled. Patients were asked to provide their complete medical and biochemical record from their general practitioner.

RESULTS

509 patients, mean age 74.8±6.5 years, 57.4% female, participated in the study. 164 PIM were identified in 139 patients (27.3%). The most common were: long-term use of long-acting benzodiazepines (20.7%), use of non-steroidal antiinflammatory drugs (NSAID) in patients with moderate-severe hypertension (20.1%), use of theophylline as monotherapy for chronic obstructive pulmonary disease (COPD, 15.9%) and use of aspirin without appropriate indication (15.2%). Patients with more than four prescpritions had a higher risk for PIM (OR 2.85, 95% CI 1.97-4.14, p<0.001). There were 439 PPO, identified in 257, (50.5%) patients. Predictors for PPO were older age, presence of diabetes, myocardial infarction, osteoporosis, stroke, COPD and/or angina pectoris.

CONCLUSION

STOPP/START criteria may be useful in identifying inappropriate prescribing and improving the current prescribing practices. Pharmacists should focus more on patients with more than four medications and/or patients with gout or pain accompanied with arterial hypertension because those patient may be at higher risk of PIM. Additionlly, patients older than 74 years with diabetes, osteoporosis, myocardial infarction, stroke, angina pectoris and/or COPD may have an increased risk of PPO.

[Role of clinical pharmacist in the therapeutical optimization in geriatric outpatient hospital]

SETTING

Cares in outpatient hospital for elderly patients is a period of interest for multidisciplinary reassessment and pharmaceutical care of the prescription. The objective is to present the implementation of the pharmaceutical care activity at the outpatient hospital.

METHODS

Between August and October 2011, elderly patients hospitalized in the outpatient hospital for a brief appraisal had a pharmaceutical care. The clinician introduced pharmaceutical reviews in the synthesis letter for general practitioner. An analysis of the activity was carried out over 3 months.

RESULTS

A pharmaceutical care had been realized for 67 patients, mean age of 81.7 years. Among medical related problems identified, 39.6% were for potentially unnecessary medication. A stop was proposed for 44% of pharmaceutical interventions. A total of 91 pharmaceutical interventions and 13 recommendations were made and 34% of patients had potentially inappropriate medication.

CONCLUSION

According to the objective to reduce the therapeutics contributing to the iatrogenesis, this approach allowed us to undertake a multidisciplinary collaboration oriented toward the relay between hospital and city cares.

PROPER I: frequency and appropriateness of psychotropic drugs use in nursing home patients and its associations: a study protocol

BACKGROUND

Nursing home patients with dementia use psychotropic drugs longer and more frequently than recommended by guidelines implying psychotropic drugs are not always prescribed appropriately. These drugs can have many side effects and effectiveness is limited. Psychotropic drug use between nursing home units varies and is not solely related to the severity of neuropsychiatric symptoms. There is growing evidence indicating that psychotropic drug use is associated with environmental factors, suggesting that the prescription of psychotropic drugs is not only related to (objective) patient factors. However, other factors related to the patient, elderly care physician, nurse and the physical environment are only partially identified. Using a mixed method of qualitative and quantitative research, this study aims to understand the nature of psychotropic drug use and its underlying factors by identifying: 1) frequency and appropriateness of psychotropic drug use for neuropsychiatric symptoms in nursing home patients with dementia, 2) factors associated with (appropriateness of) psychotropic drug use.

METHODS

A cross-sectional mixed methods study. For the quantitative study, patients with dementia (n = 540), nursing staff and elderly care physicians of 36 Dementia Special Care Units of 12 nursing homes throughout the Netherlands will be recruited. Six nursing homes with high average rates and six with low average rates of psychotropic drug use, based on a national survey about frequency of psychotropic drug use on units, will be included. Psychotropic drugs include antipsychotics, anxiolytics, hypnotics, antidepressants, anticonvulsants and anti-dementia drugs. Appropriateness will be measured by an instrument based on the Medication Appropriateness Index and current guidelines for treatment of neuropsychiatric symptoms. Factors associated to psychotropic drug use, related to the patient, elderly care physician, nurse and physical environment, will be explored using multilevel regression analyses. For the qualitative study, in depth interviews with staff will be held and analyzed to identify and explore other unknown factors.

DISCUSSION

This study will provide insight into factors that are associated with the frequency and appropriateness of psychotropic drug use for neuropsychiatric symptoms. Understanding psychotropic drug use and its associations may contribute to better dementia care.

Improving psychotropic drug prescription in nursing home patients with dementia: design of a cluster randomized controlled trial

BACKGROUND

Neuropsychiatric symptoms are highly prevalent in nursing home patients with dementia. Despite modest effectiveness and considerable side effects, psychotropic drugs are frequently prescribed for these neuropsychiatric symptoms. This raises questions whether psychotropic drugs are appropriately prescribed. The aim of the PROPER (PRescription Optimization of Psychotropic drugs in Elderly nuRsing home patients with dementia) II study is to investigate the efficacy of an intervention for improving the appropriateness of psychotropic drug prescription in nursing home patients with dementia.

METHODS/DESIGN

The PROPER II study is a multi-center cluster randomized controlled, pragmatic trial using parallel groups. It has a duration of eighteen months and four six-monthly assessments. Six nursing homes will participate in the intervention and six will continue care as usual. The nursing homes will be located throughout the Netherlands, each participating with two dementia special care units with an average of fifteen patients per unit, resulting in 360 patients. The intervention consists of a structured and repeated multidisciplinary medication review supported by education and continuous evaluation. It is conducted by pharmacists, physicians, and nurses and consists of three components: 1) preparation and education, 2) conduct, and 3) evaluation/guidance. The primary outcome is the proportion of patients with appropriate psychotropic drug use. Secondary outcomes are the overall frequency of psychotropic drug use, neuropsychiatric symptoms, quality of life, activities of daily living, psychotropic drug side effects and adverse events (including cognition, comorbidity, and mortality). Besides, a process analysis on the intervention will be carried out.

DISCUSSION

This study is expected to improve the appropriateness of psychotropic drug prescription for neuropsychiatric symptoms in nursing home patients with dementia by introducing a structured and repeated multidisciplinary medication review supported by education and continuous evaluation.

Studies to reduce unnecessary medication use in frail older adults: a systematic review

BACKGROUND

Overuse of unnecessary medications in frail older adults with limited life expectancy remains an understudied challenge.

OBJECTIVE

To identify intervention studies that reduced use of unnecessary medications in frail older adults. A secondary goal was to identify and review studies focusing on patients approaching end of life. We examined criteria for identifying unnecessary medications, intervention processes for medication reduction, and intervention effectiveness.

METHODS

A systematic review of English articles using MEDLINE, EMBASE, and International Pharmaceutical Abstracts from January 1966 to September 2012. Additional studies were identified by searching bibliographies. Search terms included prescription drugs, drug utilization, hospice or palliative care, and appropriate or inappropriate. A manual review of 971 identified abstracts for the inclusion criteria (study included an intervention to reduce chronic medication use; at least 5 participants; population included patients aged at least 65 years, hospice enrollment, or indication of frailty or risk of functional decline-including assisted living or nursing home residence, inpatient hospitalization) yielded 60 articles for full review by 3 investigators. After exclusion of review articles, interventions targeting acute medications, or studies exclusively in the intensive care unit, 36 articles were retained (including 13 identified by bibliography review). Articles were extracted for study design, study setting, intervention description, criteria for identifying unnecessary medication use, and intervention outcomes.

RESULTS

The studies included 15 randomized controlled trials, 4 non-randomized trials, 6 pre-post studies, and 11 case series. Control groups were used in over half of the studies (n = 20). Study populations varied and included residents of nursing homes and assisted living facilities (n = 16), hospitalized patients (n = 14), hospice/palliative care patients (n = 3), home care patients (n = 2), and frail or disabled community-dwelling patients (n = 1). The majority of studies (n = 21) used implicit criteria to identify unnecessary medications (including drugs without indication, unnecessary duplication, and lack of effectiveness); only one study incorporated patient preference into prescribing criteria. Most (25) interventions were led by or involved pharmacists, 4 used academic detailing, 2 used audit and feedback reports targeting prescribers, and 5 involved physician-led medication reviews. Overall intervention effect sizes could not be determined due to heterogeneity of study designs, samples, and measures.

CONCLUSIONS

Very little rigorous research has been conducted on reducing unnecessary medications in frail older adults or patients approaching end of life.

A demonstration study comparing "role-emergent" versus "role-established" pharmacy clinical placement experiences in long-term care facilities

BACKGROUND

Increasing challenges to recruit hospital sites with full-time on-site pharmacy preceptors for institutional-based Advanced Pharmacy Practice Experiences (APPE) has made it necessary to consider alternate experiential models. Sites with on-site discipline specific preceptors to supervise students have typically been referred to in the literature as "role-established" sites. In British Columbia, long-term care (LTC) facilities offered a unique opportunity to address placement capacity issues. However, since the majority of these facilities are serviced by off-site community pharmacists, this study was undertaken to explore the viability of supervising pharmacy students remotely - a model referred to in the literature as "role-emergent" placements. This paper's objectives are to discuss pharmacy preceptors' and LTC non-pharmacist staff experiences with this model.

METHODS

The study consisted of three phases: (1) the development phase which included delivery of a training program to create a pool of potential LTC preceptors, (2) an evaluation phase to test the viability of the LTC role-emergent model with seven pharmacists (two role-established and five role-emergent) together with their LTC staff, and (3) expansion of LTC role-emergent sites to build capacity. Both qualitative and quantitative methods were used to obtain feedback from pharmacists and staff and t-tests and Mann-Whitney U tests were used to examine equivalency of survey outcomes from staff representing both models.

RESULTS

The 76 pharmacists who completed the training program survey rated the modules as "largely" meeting their learning needs. All five role-emergent pharmacists and 29 LTC participating staff reported positive experiences with the pharmacy preceptor-student-staff collaboration. Preceptors reported that having students work side-by-side with facility staff promoted inter-professional collaboration. The staff viewed students' presence as a mutually beneficial experience, suggesting that the students' presence had enabled them to deliver better care to the residents. As a direct result of the study findings, the annual role-emergent placement capacity was increased to over 45 by the end of the study.

CONCLUSIONS

This study demonstrated that role-emergent LTC facilities were not only viable for quality institutional APPEs but also provided more available sites, greater student placement capacity, and more trained pharmacy preceptors than could be achieved in role-established facilities.

Evaluation of clinical pharmacist recommendations in the geriatric ward of a Belgian university hospital

Objective

To evaluate the type, acceptance rate, and clinical relevance of clinical pharmacist recommendations at the geriatric ward of the Ghent university hospital.

Methods

The clinical pharmacist evaluated drug use during a weekly 2-hour visit for a period of 4 months and, if needed, made recommendations to the prescribing physician. The recommendations were classified according to type, acceptance by the physician, prescribed medication, and underlying drug-related problem. Appropriateness of prescribing was assessed using the Medication Appropriateness Index (MAI) before and after the recommendations were made. Two clinical pharmacologists and two clinical pharmacists independently and retrospectively evaluated the clinical relevance of the recommendations and rated their own acceptance of them.

Results

The clinical pharmacist recommended 304 drug therapy changes for 100 patients taking a total of 1137 drugs. The most common underlying drug-related problems concerned incorrect dose, drug–drug interaction, and adverse drug reaction, which appeared most frequently for cardiovascular drugs, drugs for the central nervous system, and drugs for the gastrointestinal tract. The most common type of recommendation concerned adapting the dose, and stopping or changing a drug. In total, 59.7% of the recommendations were accepted by the treating physician. The acceptance rate by the evaluators ranged between 92.4% and 97.0%. The mean clinical relevance of the recommendations was assessed as possibly important (53.4%), possibly low relevance (38.1%), and possibly very important (4.2%). A low interrater agreement concerning clinical relevance between the evaluators was found: kappa values ranged between 0.15 and 0.25. Summated MAI scores significantly improved after the pharmacist recommendations, with mean values decreasing from 9.3 to 6.2 (P < 0.001).

Conclusion

In this study, the clinical pharmacist identified a high number of potential drug-related problems in older patients; however, the acceptance of the pharmacotherapy recommendations by the treating physician was lower than by a panel of evaluators. This panel, however, rated most recommendations as possibly important and as possibly having low relevance, with low interrater reliability. As the appropriateness of prescribing seemed to improve with decreased MAI scores, clinical pharmacy services may contribute to the optimization of drug therapy in older inpatients.

Clinical pharmacist evaluation of medication inappropriateness in the emergency department of a teaching hospital in Malta

Appropriate prescribing remains an important priority in all medical areas of practice.

Objective

The objective of this study was to apply a Medication Appropriateness Index (MAI) to identify issues of inappropriate prescribing amongst patients admitted from the Emergency Department (ED).

Methods

This study was carried out at Malta's general hospital on 125 patients following a two-week pilot period on 10 patients. Patients aged 18 years and over and on medication therapy were included. Medication treatment for inappropriateness was assessed by using the MAI. Under-prescribing was also screened for.

Results

Treatment charts of 125 patients, including 697 medications, were assessed using a MAI.
