Measuring Quality of Life in Deprescribing Trials: A Scoping Review.

BACKGROUND: Quality of life (QoL) is an important outcome to capture in clinical trials evaluating deprescribing interventions. OBJECTIVE: We aimed to conduct a scoping review to examine how QoL has been measured in deprescribing trials among older people and identify potentially relevant QoL scales, to better inform QoL measurement in future deprescribing trials. METHODS: We searched MEDLINE, Embase, PsycINFO, the Cochrane Central Register of Controlled Trials, Google Scholar, Epistemonikos, ClinicalTrials.gov, and reference lists of eligible studies (from inception to October 2023). We included randomized and non-randomized comparative studies with a control group that evaluated deprescribing and polypharmacy reduction interventions in people ≥ 65 years of age and measured QoL as an outcome. We also included studies describing the development and validation of QoL scales related to deprescribing, polypharmacy, or medication burden in adults ≥ 18 years of age. Two independent reviewers screened titles and abstracts, then full texts. Two independent reviewers extracted data from 25% of eligible studies in order to verify agreement, then a single reviewer extracted data from the remaining studies, which a second reviewer cross-checked. We critically appraised scales based on the COSMIN checklist. RESULTS: We retrieved 7290 articles, of which 52 were eligible for inclusion, including 44 deprescribing trials and eight scale development studies. From these studies, we found 21 scales that have been used in the context of deprescribing/polypharmacy (12 generic scales used in clinical trials and nine medication-specific scales). Variations of the generic EQ-5D were the most used scales. The measurement properties of scales for capturing changes in QoL from deprescribing were uncertain. Medication-specific QoL scales have not been employed in deprescribing clinical trials and thus, their performance in this context is also not clear. CONCLUSIONS: Several existing QoL scales have been applied to the context of deprescribing/polypharmacy clinical trials, and new scales specific to the problem have been proposed. If deprescribing does impact QoL, our findings suggest it is uncertain whether existing QoL scales can practically and reliably capture such a change or whether any scale is best. However, this review compares various aspects of the scales that researchers and clinicians can consider in decisions about measuring QoL in deprescribing trials, and in planning future research.

Attitudes towards video communication for New Medicine Service at community pharmacies - A qualitative pilot study.

Background: New Medicine Service (NMS) is a community pharmacy service that can increase adherence among patients with a newly diagnosed chronic disease. NMS must be carried out by a pharmacist, which is a barrier for some pharmacy units with no pharmacist physically present. Video communication might be a way to overcome this barrier. Objective: This study aims to explore both patients' and community pharmacy staff's attitudes of video-based NMS in a community pharmacy setting. Methods: Semi-structured, telephone interviews were conducted with patients who have participated in video-based NMS. Focus groups with pharmacists who have carried out the video-based NMS and with staff that referred patients to the video-based NMS were conducted at community pharmacies. Thematic inductive analysis was used to analyse the interviews and focus groups. Results: In total, 10 patient interviews were conducted, along with one focus group with four pharmacists and one focus group with 10 referring staff. Three main themes emerged during the analysis: (i) Talking to a screen, (ii) content of the NMS, and (iii) tackling the technique. Patients reported that their questions for the pharmacists were the same as if the NMS had been face-to-face. Pharmacists felt that they appeared more professional on video and that non-medical related conversation was reduced compared with ordinary face-to-face NMS. The referring staff either preferred referring to a video-based NMS over an ordinary face-to-face NMS or had no preferences. Conclusions: Both patients and pharmacy staff had a positive attitude towards the video-based NMS, the content of the NMS and the performance of the IT-system. The consulting time was reduced for video-based NMS compared to face-to-face NMS, but that did not affect the medical related content of the NMS, which indicates that video-based NMS is possible without compromising the health related content.

Multidisciplinary telephone conferences about medication therapy after discharge of older inpatients: a feasibility study.

Background Studies have shown poor post-discharge implementation by the general practitioner of changes made to patients' medication during admission. Objective To assess the feasibility of conducting telephone conferences delivering information about changes in older patients' medications from hospital to general practitioners. Setting Two departments of geriatric medicine in a Danish routine healthcare setting. Method Older polypharmacy patients (≥ 65 years and ≥ 5 prescriptions) consecutively admitted were eligible for inclusion. Telephone conferences based on a review of these patient's medication therapy during hospital stay were arranged between a pharmacist and a geriatrician from the hospital, and a general practitioner. Interviews were conducted with pharmacists, geriatricians, and general practitioners about their perspectives on the feasibility of telephone conferences. Interviews were analyzed using systematic text condensation. Main outcome measure The proportion of telephone conferences conducted and perspectives on the feasibility of the study. Results A total of 113 patients were included and 82 patients (75%) were eligible for telephone conferences. A total of 40 (49%) telephone conferences were conducted. The main reasons for conferences not being conducted were general practitioners not wanting to participate or not returning the calls from the pharmacists. Three themes emerged from the qualitative analysis: considerations on planning and running the project, Barriers, facilitators, and implications of the telephone conference, and Actual and desirable cross-sectorial communication. Conclusion Telephone conferences were only possible for half of the patients. The participating general practitioners, pharmacists and geriatricians expressed varied benefit and agreed that telephone conferences were mainly relevant for complex patients.

"I simply don't know, because I don't know which drugs I get": Perspectives on deprescribing among older adults with limited life expectancy and their relatives.

Use of medications of questionable benefit is common in end of life care. In order to effectively carry out deprescribing, it is important to gain insight into the perspectives of patients and their relatives. Thus, our objective was to explore perspectives on deprescribing among older adults with limited life expectancy and their relatives. We conducted semi-structured interviews with ten nursing home residents and nine relatives. Interviews were analysed using systematic text condensation. Four main themes were identified: "Medication as a necessity and to feel well," "Frailty as a barrier for taking responsibility," "Patient autonomy and faith in authority" and "A wish for being involved." Most participants had not considered the possibility of deprescribing but were open towards medication change if proposed by a healthcare professional. Most participants did not have in-depth knowledge about medication but would like to be informed or involved in decisions. The participants generally had faith in healthcare professionals despite limited contact. Our study implies that older adults with limited life expectancy and their relatives are generally interested in deprescribing activities; however, the initiative of deprescribing lies with the healthcare professionals.

Attitudes Towards Deprescribing Among Older Adults with Limited Life Expectancy and Their Relatives: A Systematic Review.

BACKGROUND: Deprescribing is of particular importance in older adults with limited life expectancy since this population group is highly susceptible to the potential harms of inappropriate medications. OBJECTIVE: This systematic review aimed to explore attitudes towards deprescribing among older adults with limited life expectancy and their relatives. METHODS: A systematic literature review was conducted in the MEDLINE and EMBASE databases from inception to October 2019. Inclusion criteria were studies specifically describing attitudes towards deprescribing among older adults (≥ 65 years) with limited life expectancy and/or their relatives regardless of study type. Results were analyzed, inspired by the Joanna Briggs Institute's method for synthesis of qualitative data. RESULTS: A total of 842 studies were identified and screened; 84 were full-text assessed for eligibility and 7 were ultimately included. Two studies investigated the attitudes of older adults with limited life expectancy and their relatives towards deprescribing of statins and donepezil, respectively, while the five remaining studies related to attitudes towards deprescribing in general. Four main themes were identified: (1) the well-being of older adults with limited life expectancy; (2) involvement of older adults and their relatives in deprescribing; (3) the role of health care professionals in deprescribing; and (4) medication-related factors affecting deprescribing. Within each of these themes, several subthemes were identified. CONCLUSIONS: Attitudes towards deprescribing among older adults with limited life expectancy and their relatives vary and highlight several barriers and enablers to the deprescribing process. Several of these factors must be addressed to successfully implement deprescribing initiatives in this patient group.

Translation and psychometric validation of a Danish version of the medication-related quality of life scale.

Background Generic and disease specific health-related quality of life scales have been found to be non-responsive to changes in medications in polypharmacy patients. The Taiwanese medication-related quality of life (MRQoL) scale aims to measure the effect of medication use on patients' quality of life. Objective To evaluate the psychometric properties of the Danish translation of MRQoL in a population of patients with polypharmacy. Setting Polypharmacy patients waiting for services at a community pharmacy or hospital in Denmark. Method The original MRQoL included 14 items. It was forward-translated into Danish and backward-translated into Chinese according to a modified translation protocol proposed by Sousa and Rojjanasrirrat et al. The translation was pre-tested, adjusted, and administered to polypharmacy patients. The factor structure was examined using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Internal consistency reliability was evaluated, and criterion validity assessed using the beliefs about medicines questionnaire (BMQ) and SF-12v2. Known-group validity was carried out on age, number of medicines and setting. Main outcome measure Validity of the Danish version of the MRQoL-scale. Results 164 patients completed the questionnaire. EFA of all 14 items resulted in a two-factor structure, accounting for 72.8% of the total variance. The two factors were named "Energy/Concentration" (7 items) and "Feelings/Social" (7 items). Items correlating over 0.80 were removed leaving 11 items (Model 1). This model was further reduced to 8 items (Model 2) based on Cronbach's alpha. CFA confirmed the two-factor structure of both models. Model 2 fitted data without having to define covariations between error terms. Both factors showed high internal consistency reliability (Cronbachs' alpha 0.901-0.932). Ceiling effects were detected for both factors. Criterion validity was demonstrated via its significant correlations with SF-12vs2 subscales (Spearman's rho 0.340-0.353) and BMQ Concern (Spearman's rho - 0.451 to - 0.347). There was a statistically significant difference in relation to total scores of the MRQoL for age and number of drugs taken, indicating known-group validity. Conclusion The Danish translation of the MRQoL instrument showed measurement properties indicating a well-defined two-factor structure with high internal reliability, concurrent criterion validity, and known group validity. However, challenges remain with ceiling effects and efforts should be put into further development of the instrument.

" Above All, It's a Matter of This Person's Quality of Life": Health Care Professionals' Perspectives on Deprescribing in Older Patients With Limited Life Expectancy.

BACKGROUND AND OBJECTIVES: Deprescribing may be particularly relevant in older people with limited life expectancy. In order to effectively carry out deprescribing in this population, it is important to understand the perspectives of the full spectrum of health care professionals (HCPs) involved in the management of these patients' medication. Thus, we aimed to explore different HCPs' perspectives on deprescribing in older patients with limited life expectancy. RESEARCH DESIGN AND METHODS: Six qualitative focus group interviews were conducted using a semistructured approach. The groups comprised HCPs from both primary and secondary care, including family physicians (FPs), geriatricians, clinical pharmacologists, clinical pharmacists, nurses, and health care assistants. Interviews were audio recorded and transcribed verbatim. Results were analyzed using systematic text condensation. RESULTS: A total of 32 HCPs participated in the study (median age of 40.5 years; 22% male). The analysis elicited three main themes related to HCPs' perspectives on deprescribing in older patients with limited life expectancy: (a) Approaching deprescribing, (b) Taking responsibility, and (c) Collaboration across professions. Within themes, subthemes were identified and analyzed. DISCUSSION AND IMPLICATIONS: Our results imply that different groups of HCPs consider deprescribing an essential aspect of providing good care for older people with limited life expectancy and find that all HCPs play a crucial role in the deprescribing process, with FPs having the primary responsibility. In order to facilitate deprescribing among this population, however, the collaboration between different HCPs should be improved.

Frequency of undocumented medication discrepancies in discharge letters after hospitalization of older patients: a clinical record review study.

Transitions of care may result in medication errors, when information about a patient's medications is not communicated sufficiently. In this clinical record review study, we aimed to evaluate the frequency of undocumented medication discrepancies at discharge from hospital and evaluate which patient characteristics could be associated with undocumented medication discrepancies. Preadmission medication lists were compared against the medication list in the discharge letters, taking into account medication changes documented in the patient record throughout the inpatient stay and in the discharge summary. Out of 200 patients, 174 (87%) were affected by at least one undocumented medication discrepancy, mostly for regular medication. Of the 1972 medications used, 744 (38%) medications were changed without documentation in the patient record, the majority being over-the-counter supplements and herbal medications. Polypharmacy at admission and discharge was associated with increased undocumented medication discrepancies. This study indicates a lack of medication reconciliation during inpatient stay. Correct and complete medication lists at admission and discharge may resolve many of these discrepancies, supporting patient safety at transitions of care.

Health care professionals' attitudes towards deprescribing in older patients with limited life expectancy: A systematic review.

AIMS: The aim of this systematic review was to explore health care professionals' attitudes towards deprescribing in older people with limited life expectancy. METHODS: A systematic literature search was conducted from inception to December 2017 using MEDLINE, EMBASE and CINAHL. Studies were included if they specifically concerned older people (≥65 years) with limited life expectancy, including those residing in any type of aged care facility, or were based on representative patient profiles. Results were analyzed inspired by the Joanna Briggs Institute's method for synthesis of qualitative data. Studies were characterized using a checklist for reporting of qualitative research. RESULTS: Eight studies were included. Six studies explored health care professionals' views on deprescribing in general, and two studies focused specifically on psychotropic agents. All eight studies explored the views of physicians, mostly general practitioners, while three studies also considered other health care professionals. Four themes related to health care professionals' attitudes towards deprescribing were identified: (i) patient and relative involvement; (ii) the importance of teamwork; (iii) health care professionals' self-assurance and skills; and (iv) the impact of organizational factors. Within each of these themes, 3-4 subthemes were identified and analysed. CONCLUSIONS: Our results suggest that health care professionals' decisions to engage in deprescribing activities with older people with limited life expectancy depend on multiple factors which are highly interdependent. Consequently, there is an urgent need for more research on how to approach deprescribing in clinical practice within this population.

Effect of a medicines management model on medication-related readmissions in older patients admitted to a medical acute admission unit-A randomized controlled trial.

RATIONALE, AIMS, AND OBJECTIVES: Medication-related problems are frequent and can lead to serious adverse events resulting in increased morbidity, mortality, and costs. Medication use in frail older patients is even more complex. The aim of this study was to investigate the effect of a pharmacist-led medicines management model among older patients at admission, during inpatient stay and at discharge on medication-related readmissions. METHOD: A randomized controlled trial conducted at the acute admission unit in a Danish hospital with acutely admitted medical patients, randomized to either a control group or one of two intervention groups. The intervention consisted of pharmacist-led medication review and patient interview upon admission (intervention ED) or pharmacist-led medication review and patient interview upon admission, medication review during inpatient stay, and medication report and patient counselling at discharge (intervention STAY). RESULTS: In total, 600 patients were included. The pharmacist identified 920 medication-related problems with 57% of the recommendations accepted by the physician. After 30 days, 25 patients had a medication-related readmission, with no statistical significant difference between the groups on either primary or secondary outcomes. CONCLUSIONS: This study showed that a clinical pharmacist can be used to identify and solve medication-related problems, but this study did not find any effect on the selected outcomes. The frequency of medication-related readmissions was low, leaving little room for improvement. Future research should consider other study designs or outcome measures.

Tools for Deprescribing in Frail Older Persons and Those with Limited Life Expectancy: A Systematic Review.

OBJECTIVES: To summarize available tools that can assist clinicians in identifying and reducing or stopping (deprescribing) potentially inappropriate medications and that specifically consider frailty or limited life expectancy. DESIGN: Systematic review and narrative synthesis. SETTING: We searched MEDLINE (via Ovid SP), EMBASE (via Ovid SP), and CINAHL from inception to December 2017, along with grey literature. We included articles that described a tool to guide deprescribing of medications. PARTICIPANTS: Frail older persons and older persons with limited life expectancy. MEASUREMENTS: Narrative description of tools. RESULTS: We identified 15 tools and organized them into three main categories: tools (n = 2) that described a model or framework for approaching deprescribing, tools (n = 9) that outlined a deprescribing approach for the entire medication list, and tools (n = 4) that provided medication-specific advice. The complexity of the tools ranged from simple lists to detailed, step-wise protocols. The development methodology varied widely, and the methods used to synthesize the tools were generally not well described. Most tools were based on expert opinion. Only four of the 15 tools have been tested in clinical practice (in very low-quality studies). CONCLUSION: Tools exist to help clinicians deprescribe in frail older persons and those with limited life expectancy. These tools may assist clinicians at various stages in the deprescribing process. However, it remains to be investigated whether use of such tools in practice is likely to improve clinical outcomes or reduce inappropriate medication use. J Am Geriatr Soc 67:172-180, 2019.

Multifaceted Pharmacist-led Interventions in the Hospital Setting: A Systematic Review.

Clinical pharmacy services often comprise complex interventions. In this MiniReview, we conducted a systematic review aiming to evaluate the impact of multifaceted pharmacist-led interventions in a hospital setting. We searched MEDLINE, Embase, Cochrane Library and CINAHL for peer-reviewed articles published from 2006 to 1 March 2018. Controlled trials concerning hospitalized patients in any setting receiving patient-related multifaceted pharmacist-led interventions were considered. All types of outcome were accepted. Inclusion and data extraction were performed. Study characteristics were collected, and risk of bias assessment was conducted utilizing the Cochrane Risk of Bias tools. All stages were conducted by at least two independent reviewers. The review was registered in PROSPERO (CRD42017075808). A total of 11,896 publications were identified, and 28 publications were included. Of these, 17 were conducted in Europe. Six of the included publications were multi-centre studies, and 16 were randomized trials. Usual care was the comparator. Significant results on quality of medication use were reported as positive in eleven studies (n = 18; 61%) and negative in one (n = 18, 6%). Hospital visits were reduced significantly in seven studies (n = 16; 44%). Four studies (n = 12; 33%) reported a positive significant effect on either length of stay or time to revisit, and one study reported a negative effect (n = 12; 6%). All studies investigating mortality (n = 6), patient-reported outcome (n = 7) and cost-effectiveness (n = 1) showed no significant results. This MiniReview indicates that multifaceted pharmacist-led interventions in a hospital setting may improve the quality of medication use and reduce hospital visits and length of stay, while no effect was seen on mortality, patient-reported outcome and cost-effectiveness.

Pharmacist-led interventions improve quality of medicine-related healthcare service at hospital discharge.

OBJECTIVES: This study aims to investigate the effects on quality of the medicine-related healthcare service provided at hospital discharge after implementing a pharmacist-led patient-centred discharge service. METHODS: Medical in-patients ready for discharge and prescribed at least six medicines were eligible for inclusion in this descriptive intervention study. A ward-based clinical pharmacist provided a patient-centred discharge service which comprised medication review (including reconciliation if appropriate), medication counselling and verification of the medication discharge summary plans. Satisfaction with the pharmacist-led interventions was collected by questionnaires and follow-up telephone interviews. A quality audit on the medical information stated in the discharge summary plans was conducted. RESULTS: A total of 313 medical records were prospectively reviewed by the clinical pharmacist, and 745 medicine-related problems each leading to a clinical recommendation were identified. The total rate of acceptance by the physicians was found to be 84%. The quality audit revealed a significantly higher quality of the medication discharge summary plans sent to primary care regarding content of updated lists of medication after the pharmacist's intervention. The involved physicians stated that contributions from the pharmacist had eased their workload and helped them to obtain a more rational prescribing practice. The interviewed patients felt secure and well-informed about their medicines. CONCLUSIONS: Contributions from clinical pharmacists can improve both the quality of and satisfaction with the medicine-related healthcare service provided at hospital discharge and secure continuity of medical care at transitions.

Description of a practice model for pharmacist medication review in a general practice setting.

BACKGROUND: Practical descriptions of procedures used for pharmacists' medication reviews are sparse. OBJECTIVE: To describe a model for medication review by pharmacists tailored to a general practice setting. METHODS: A stepwise model is described. The model is based on data from the medical chart and clinical or laboratory data. The medication review focuses on the diagnoses of the patient instead of the individual drugs. Patient interviews are not part of the model. The model was tested in a pilot study by conducting medical reviews on 50 polypharmacy patients (i.e. receiving 7 or more drugs for regular use). RESULTS: The model contained seven main steps. Information about the patient and current treatment was collected in the first three steps, followed by identification of possible interventions related to either diagnoses or drugs in the fourth and fifth step. The sixth and seventh step concerned the reporting of interventions and the considerations of the GPs. 208 interventions were proposed among the 50 patients. The acceptance rate among the GPs was 82%. The most common interventions were lack of clinical or laboratory data (n=57, 27%) and drugs that should be discontinued as they had no indication (n=47, 23%). Most interventions were aimed at cardiovascular drugs. CONCLUSION: We have provided a detailed description of a practical approach to pharmacists' medication review in a GP setting. The model was tested and found to be usable, and to deliver a medication review with high acceptance rates.

A national drug related problems database: evaluation of use in practice, reliability and reproducibility.

BACKGROUND: A drug related problems database (DRP-database) was developed on request by clinical pharmacists. The information from the DRP-database has only been used locally e.g. to identify focus areas and to communicate identified DRPs to the hospital wards. Hence the quality of the data at the national level is unknown, which may compromise national analyses for benchmarking and identification of national focus areas. OBJECTIVE: The aim of the study was to evaluate the use in practice, reliability and reproducibility of the DRPs documented in the Danish drug related problems database. SETTING: Danish hospital pharmacies. METHODS: Practice use of the DRP-database was explored by an electronic questionnaire distributed to hospital pharmacies, and consisted of questions regarding current and previous use of the DRP-database. The reliability was evaluated by comparing the categorization of 24 cases by clinical pharmacists with categorization performed by the project group. Reproducibility was explored by re-categorization of a sample of existing records in the DRP-database by two project group members individually. MAIN OUTCOME MEASURES: Observed proportion of agreement and Fleiss' kappa as measures of inter-rater reliability and reproducibility. RESULTS: The practice use study of 12 hospital pharmacy locations revealed that when implementing the DRP-database, the majority of identified DRPs are documented in the DRP-database, however, some variations throughout the country exist. The interrater reliability study of 34 clinical pharmacists showed high inter-rater reliability with the project group (Fleiss' kappa = 0.79 with 95 % CI (0.70; 0.88)), and the reproducibility study also documented high inter-rater reliability of a sample of 379 records from the DRP-database re-categorized by two project group members (Fleiss' kappa = 0.81 with 95 % CI (0.78; 0.85)). CONCLUSION: The study showed high reliability and reproducibility of the DRP-database, however, some local variation in the use of the DRP-database throughout the country existed affecting the overall quality. These findings indicate that data in the DRP-database may be pooled, and national analyses may be conducted to explore development areas for common interest.

Characterization of drug-related problems identified by clinical pharmacy staff at Danish hospitals.

BACKGROUND: In 2010, a database of drug related problems (DRPs) was implemented to assist clinical pharmacy staff in documenting clinical pharmacy activities locally. A study of quality, reliability and generalisability showed that national analyses of the data could be conducted. Analyses at the national level may help identify and prevent DRPs by performing national interventions. OBJECTIVE: The aim of the study was to explore the DRP characteristics as documented by clinical pharmacy staff at hospital pharmacies in the Danish DRP-database during a 3-year period. SETTING: Danish hospital pharmacies. METHOD: Data documented in the DRP-database during the initial 3 years after implementation were analyzed retrospectively. The DRP-database contains DRPs reported at hospitals by clinical pharmacy staff. The analyses focused on DRP categories, implementation rates and drugs associated with the DRPs. MAIN OUTCOME MEASURE: Characteristics of DRPs. RESULTS: In total, 72,044 DRPs were documented in the DRP-database during the first 3 years of implementation, and the number of documented DRPs increased every year. An overall stable implementation rate of approximately 58 % was identified. The DRPs identified were multi-facetted, however evenly distributed for each of the 3 years. The most frequently identified DRP categories were: "Dose", followed by "Nonadherence to guidelines" and "Supplement to treatment". The highest implementation rates were found for the following DRP categories: "Non-adherence to guidelines" (79 %) followed by "Therapeutic duplication" (73 %) and "Dosing time and interval" (70 %). Even though the top 25 drugs were involved in 58 % of all DRPs, multiple drugs were associated with DRPs. The drugs most frequently involved in DRPs were paracetamol (4.6 % of all DRPs), simvastatin (3.0 %), lansoprazole (2.7 %), morphine (2.6 %) and alendronic acid (2.4 %). CONCLUSIONS: The study found that a national database on DRPs contained multi-facetted DRPs, however evenly distributed for each of the 3 years. Even though the top 25 drugs were involved in 58 % of all DRPs, multiple drugs were associated with DRPs. The study emphasizes the importance of detecting and intervening for DRPs.

Medication reviews by clinical pharmacists at hospitals lead to improved patient outcomes: a systematic review.

Suboptimal medication use may lead to morbidity, mortality and increased costs. To reduce unnecessary patient harm, medicines management including medication reviews can be provided by clinical pharmacists. Some recent studies have indicated a positive effect of this service, but the quality and outcomes vary among studies. Hence, there is a need for compiling the evidence within this area. The aim of this systematic MiniReview was to identify, assess and summarize the literature investigating the effect of pharmacist-led medication reviews in hospitalized patients. Five databases (MEDLINE, EMBASE, CINAHL, Web of Science and the Cochrane Library) were searched from their inception to 2011 in addition to citation tracking and hand search. Only original research papers published in English describing pharmacist-led medication reviews in a hospital setting including minimum 100 patients or 100 interventions were included in the final assessment. A total of 836 research papers were identified, and 31 publications were included in the study: 21 descriptive studies and 10 controlled studies, of which 6 were randomized controlled trials. The pharmacist interventions were well implemented with acceptance rates from 39% to 100%. The 10 controlled studies generally show a positive effect on medication use and costs, satisfaction with the service and positive as well as insignificant effects on health service use. Several outcomes were statistically insignificant, but these were predominantly associated with low sample sizes or low acceptance rates. Therefore, future research within this area should be designed using rigorous design, large sample sizes and includes comparable outcome measures for patient health outcomes.
