Clinical pharmacists' perspective of medication adherence support in Ethiopian hospital settings: a qualitative study.

BACKGROUND: Hospital pharmacists can assist patients with medication adherence in a hospital setting. No studies have explored the views of hospital pharmacists on medication adherence. OBJECTIVES: The study aimed to explore Ethiopian clinical pharmacists' understanding of and experience with medication adherence, and identify strategies for medication adherence support. METHODS: Semi-structured interviews were conducted via ZOOM/Skype. Hospital pharmacists were recruited through a professional network and snowball sampling. All interviews were audio recorded, transcribed verbatim, translated into English and analysed using thematic analysis techniques. The data coding followed a hybrid deductive and inductive approach. KEY FINDINGS: Fourteen Ethiopian clinical pharmacists participated in the study. Analysis yielded five main themes including: medication adherence definition and measurement; pharmacists' perceived roles; enablers of medication adherence; barriers to medication adherence; and ways forward. Participants indicated that accurately assessing medication adherence was complicated because of an absence of cost-effective and validated tools. Pharmacist education, clinical pharmacy services, physical structure, sources of medication information, and government initiatives to reduce financial burdens were the facilitators identified. Eight barriers were identified, and these were broadly classified as factors intrinsic or extrinsic to the patient. CONCLUSIONS: Medication adherence support could face barriers intrinsic or extrinsic to patients. Strategies were proposed to overcome the identified barriers and to harness existing facilitators. These strategies included the need for validated local language medication adherence tools, instituting regular adherence measurement and prioritizing patients for available interventions. Patient's preferred dosage form should be considered along with medication complexity and medication knowledge when supporting medication adherence.

Measurement Properties of Patient-Reported Outcome Measures for Medication Adherence in Cardiovascular Disease: A COSMIN Systematic Review.

BACKGROUND AND OBJECTIVE: Several medication adherence patient-reported outcome measures (MA-PROMs) are available for use in patients with cardiovascular disease (CVD); however, little evidence is available on the most suitable MA-PROM to measure medication adherence in patients with CVD. The aim of this systematic review is to synthesise the measurement properties of MA-PROMs for patients with CVD and identify the most suitable MA-PROM for use in clinical practice or future research in patients with CVD. METHODS: An electronic search of nine databases (PubMed, MEDLINE, CINAHL, ProQuest Health and Medicine, Cochrane Library, PsychInfo, Scopus, Embase, and Web of Science) was conducted to identify studies that have reported on at least one of the measurement properties of MA-PROMs in patients with CVD. The methodological quality of the studies included in the systematic review was evaluated using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. RESULTS: A total of 40 MA-PROMs were identified in the 84 included studies. This review found there is a lack of moderate-to-high quality evidence of sufficient content validity for all MA-PROMs for patients with CVDs. Only eight MA-PROMs were classified in COSMIN recommendation category A. They exhibited sufficient content validity with very low-quality evidence, and moderate-to-high quality evidence for sufficient internal consistency. The 28 MA-PROMs that meet the requirements for COSMIN recommendation category 'B' require further validation studies. Four MA-PROMs including Hill-Bone Compliance Medication Scale (HBMS), the five-item Medication Adherence Report Scale (MARS-5), Maastricht Utrecht Adherence in Hypertension (MUAH), and MUAH-16 have insufficient results with high quality evidence for at least one measurement property and consequently are not recommended for use in patients with CVD. Two MA-PROMs (Adherence to Refills and Medications Scale [ARMS] and ARMS-7) are comprehensive and have moderate to high quality evidence for four sufficient measurement properties. CONCLUSION: From the eight MA-PROMs in COSMIN recommendation category A, ARMS and ARMS-7 were selected as the most suitable MA-PROMs for use in patients with CVD. They are the most comprehensive with be best quality evidence to support their use in clinical practice and research.

Self-reported medication adherence tools in cardiovascular disease: protocol for a systematic review of measurement properties.

OBJECTIVE: The aim of this review is to identify high-quality, self-reported medication adherence tools for adults with cardiovascular disease to improve health outcomes. INTRODUCTION: Medication adherence is a complex concept affected by multiple factors and positively associated with clinical outcomes. Poor adherence to cardiovascular medications is a hindrance to the effective management of cardiovascular disease, leading to poor disease prognosis or increased risk of death. Valid and reliable measurement is crucial to identify patients with poor adherence, preferably before an adverse outcome occurs. INCLUSION CRITERIA: This review will consider studies that include adults, aged 18 years and over, with a diagnosis of cardiovascular disease. The construct of medication adherence has three phases: initiation, implementation and discontinuation. Included tools need to measure at least one of these phases. The review will consider studies of any study design that report on the measurement properties of self-reported medication adherence tools among adults with cardiovascular disease. METHODS: The following databases will be searched from inception to present: PubMed, MEDLINE, CINAHL, ProQuest Health and Medicine, Cochrane Library, PsycINFO, Scopus, Embase and Web of Science. Articles published in any language will be included, with no date limit. Data extraction will be performed by one reviewer and cross-checked by another reviewer. Data from the included studies will be synthesized using tables for the quality of methods, and measurement property results. SYSTEMATIC REVIEW REGISTRATION NUMBER: PROSPERO CRD42019124291.

Challenges and opportunities of clinical pharmacy services in Ethiopia: A qualitative study from healthcare practitioners' perspective.

BACKGROUND: Currently, clinical pharmacists have in-depth therapeutic knowledge and scientific skills to act as drug therapy experts in healthcare settings. OBJECTIVE: The aim of this study was to assess the opportunities and challenges of clinical pharmacy services from the health practitioners' perspective in University of Gondar (UOG) hospital Ethiopia. METHODS: A qualitative study was performed using face-to-face in-depth interviews with health practitioners who were directly involved in clinical pharmacy services (clinical pharmacists, physicians, and nurses) in UOG hospital. RESULTS: A total of 15 health professionals from various specialties were interviewed to express their views towards clinical pharmacists' competencies and identified challenges and opportunities regarding their clinical services. Based on interviewees report, the opportunities for clinical pharmacists includes acceptance of their clinical services among health specialties, new government policy and high patient load in hospital. However, inadequacy of service promotions, lack of continuity of clinical pharmacy services in wards, poor drug information services, lack of commitment, lack of confidence among clinical pharmacists, conflict of interest due to unclear scope of practice, and absence of cooperation with health workers were some of the challenges identified by the interviewees. CONCLUSION: We identified health professionals working in UOG hospital are receptive towards clinical pharmacy services, but identified some of the potential challenges that needed to be focused to strengthen and promote clinical pharmacy services. Further, the opportunities at hand also need to be utilized astutely to boost the services.

The impact of pharmacist-led medication therapy management on medication adherence in patients with type 2 diabetes mellitus: a randomized controlled study.

BACKGROUND: Poor adherence to antidiabetic medications leads to a higher rate of hospital admissions and adverse health outcomes in type 2 diabetes mellitus patients. OBJECTIVE: This study aims to evaluate whether a pharmacist-led medication therapy management, compared to the usual care, could enhance medication adherence and reduce hospital admission in patients with type 2 diabetes mellitus. METHODS: A prospective randomized controlled study was conducted in patients with type 2 diabetes mellitus from February 1 to July 30, 2016. Patients in the control group (n=65) received the usual care while patients in the intervention group (n=62) received a personalized pharmacotherapeutic care plan and diabetes education. The two groups were compared by repeated measure ANOVA at 3 and 6-months with medication adherence (using Morisky medication adherence scale) and number of hospital admissions as the main outcome variables. RESULTS: A total of 127 patients were included in the study. A marked and statistically significant increase in medication adherence from baseline to 3 and 6 months were noted in the intervention group (increased from 9.2% at baseline to 61% at 6 month) compared with the control group (increased from 13.2% at baseline (to 30.2% at 6 month; p-value<0.01). Furthermore, at the 6-month follow-up, only 23 patients in MTM group with poorly controlled blood glucose levels resulted in hospital admissions compared to 48 patients in non-MTM group, resulting in a 52.1% fewer hospital admissions (p< 0.001). CONCLUSIONS: The findings of this study implied that pharmacist-led medication therapy management might improve medication adherence and reduce number of hospitalizations in patients with type 2 diabetes mellitus. Hence, policies and guidelines should be in place in order for clinical pharmacists to fully engage in patient care and improve the medication therapy outcomes.
