Effectiveness of pharmacist-led medication reconciliation programmes on clinical outcomes at hospital transitions: a systematic review and meta-analysis

Objectives Pharmacists play a role in providing medication reconciliation. However, data on effectiveness on patients’ clinical outcomes appear inconclusive. Thus, the aim of this study was to systematically investigate the effect of pharmacist-led medication reconciliation programmes on clinical outcomes at hospital transitions. Design Systematic review and meta-analysis. Methods We searched PubMed, MEDLINE, EMBASE, IPA, CINHAL and PsycINFO from inception to December 2014. Included studies were all published studies in English that compared the effectiveness of pharmacist-led medication reconciliation interventions to usual care, aimed at improving medication reconciliation programmes. Meta-analysis was carried out using a random effects model, and subgroup analysis was conducted to determine the sources of heterogeneity. Results 17 studies involving 21 342 adult patients were included. Eight studies were randomised controlled trials (RCTs). Most studies targeted multiple transitions and compared comprehensive medication reconciliation programmes including telephone follow-up/home visit, patient counselling or both, during the first 30 days of follow-up. The pooled relative risks showed a more substantial reduction of 67%, 28% and 19% in adverse drug event-related hospital revisits (RR 0.33; 95% CI 0.20 to 0.53), emergency department (ED) visits (RR 0.72; 95% CI 0.57 to 0.92) and hospital readmissions (RR 0.81; 95% CI 0.70 to 0.95) in the intervention group than in the usual care group, respectively. The pooled data on mortality (RR 1.05; 95% CI 0.95 to 1.16) and composite readmission and/or ED visit (RR 0.95; 95% CI 0.90 to 1.00) did not differ among the groups. There was significant heterogeneity in the results related to readmissions and ED visits, however. Subgroup analyses based on study design and outcome timing did not show statistically significant results. Conclusion Pharmacist-led medication reconciliation programmes are effective at improving post-hospital healthcare utilisation. This review supports the implementation of pharmacist-led medication reconciliation programmes that include some component aimed at improving medication safety.

Epidemic of neurolathyrism in Ethiopia.

Pharmacy‐led medication reconciliation programmes at hospital transitions: a systematic review and meta‐analysis

Medication reconciliation is recognized as an important tool for the prevention of medication discrepancies and subsequent patient harm at care transitions. However, there is inconclusive evidence as to the impact of medication reconciliation at hospital transitions overall, as well as pharmacy‐led medication reconciliation services. This review sought to evaluate the impact of pharmacy‐led medication reconciliation interventions on medication discrepancies at hospital transitions and to categorize these interventions as single transition interventions or multiple transitions interventions.

Implementing ward based clinical pharmacy services in an Ethiopian University Hospital

Background Clinical pharmacy practice has developed internationally to expand the role of a pharmacist well beyond the traditional roles of compounding, dispensing and supplying drugs to roles more directly in caring for patients. Studies on the activities of the clinical pharmacist in an inpatient ward in resource constrained settings are scarce, however. Objective To assess ward based clinical pharmacy services in an internal medicine ward of Jimma University Specialized Hospital. Methods The study was carried out in the internal medicine ward from March to April, 2011 at Jimma University Specialized Hospital. The study design was a prospective observational study where pharmaceutical care services provided by clinical pharmacists for inpatients were documented over a period of two months. Interventions like optimization of rational drug use and physician acceptance of these recommendations were documented. Clinical significance of interventions was evaluated by an independent team (1 internist, 1 clinical pharmacologist) using a standardized method for categorizing drug related problems (DRPs). Results A total of 149 drug related interventions conducted for 48 patients were documented; among which 133(89.3%) were clinical pharmacists initiated interventions and 16(10.7%) interventions were initiated by other health care professionals. The most frequent DRPs underlying interventions were unnecessary drug therapy, 36(24.2%); needs additional drug therapy, 34(22.8%) and noncompliance, 29(19.5%). The most frequent intervention type was change of dosage/instruction for use, 23(15.4%). Acceptance rate by physicians was 68.4%. Among the interventions that were rated as clinically significant, 46(48.9%) and 25(26.6%) had major and moderate clinical importance respectively. Conclusions Involving trained clinical pharmacists in the healthcare team leads to clinically relevant and well accepted optimization of medicine use in a resource limited settings. This approach can likely be generalized to other health care settings in the country to improve medication outcomes.

Self-reported adverse drug reactions and their influence on highly active antiretroviral therapy in HIV infected patients: a cross sectional study

BackgroundPatients on antiretroviral therapy have higher risk of developing adverse drug reactions (ADRs). The impact of ADRs on treatment adherence, treatment outcomes and future treatment options is quiet considerable. Thus, the purpose of this study was to describe the common self-reported ADRs and their impact on antiretroviral treatment.MethodsCross-sectional study was conducted at antiretroviral therapy (ART) clinic of Gondar University Hospital. Semi-structured interview questionnaire was used to extract self-reported ADRs, socio-demographic, and psycho-social variables. Variables related to antiretroviral medication, laboratory values and treatment changes were obtained from medical charts. Chi-square and odds ratio with 95% confidence interval were used to determine the associations of dependent variables.ResultA total of 384 participants were enrolled. At least one adverse drug reaction was reported by 345 (89.8%) study participants and the mean number of ADRs reported was 3.7 (±0.2). The most frequently reported ADRs were nausea (56.5%) and headache (54.9%). About 114 (31.0%) participants considered antiretroviral therapy to be unsuccessful if ADRs occurred and only 10 (2.6%) decided to skip doses as ADRs were encountered. Based on chart review, treatment was changed for 78 (20.3%) patients and from which 79% were due to documented ADRs (p = 0.00). Among them, CNS symptoms (27.4%) and anemia (16.1%) were responsible for the majority of changes. Around four percent of patients were non-adherent to ART. Non-adhered participants and those on treatment changes were not statistically associated with self-reported ADRs. Only unemployment status (AOR = 1.76 (1.15 - 2.70), p = 0.01) and ADR duration of less than one month (AOR = 1.95 (1.28-2.98), p = 0.001) were significantly associated with self-reported adverse effects of three or more in the multivariate analysis.ConclusionSelf-reported ADRs to antiretroviral therapy are quite common. More of the reactions were of short lasting and their impact on adherence and treatment change were less likely. However, documented ADRs were the most prevalent reasons for ART switch. Moreover, the level of unemployment was a strong predictor of self-reported ADRs.

Pharmacists’ journey to clinical pharmacy practice in Ethiopia: Key informants’ perspective

Objective: Clinical pharmacy practice has developed internationally to expand the role of a pharmacist well beyond the traditional roles of compounding and supplying drugs to roles more directly in caring for patients and providing medication consultation to staff. This area of practice is at the infant stage in Ethiopia. The aim of this study was to explore key informants’ perspective in the implementation of clinical pharmacy practice in Jimma University Specialized Hospital, Ethiopia. Method: A qualitative study was conducted through in-depth interviews with the heads of departments (internal medicine, paediatrics, surgery, nurse, pharmacy, medical director, administration) and pharmacy student representatives. Qualitative data analysis was done after audiotapes were transcribed verbatim and notes were compiled. Results: All of the respondents interviewed express diverse and conflicting perspectives on pharmacists’ role, varying from a health-care professional to a business man. Despite this, the current pace of change worldwide takes the professions’ mission to that of a provider of clinical pharmacy services. The data ascertained the change in pharmacy practice, and integrating clinical pharmacy services within the health-care system should be seen as a must. Pharmacists should delineate from a business perspective and focus on widening the scope of the profession of pharmacy and should come close to the patient to serve directly. Conclusions: Although the perception of people on traditional roles of pharmacists was weak, there were promising steps in developing clinical pharmacy practice within the health-care system. Moreover, the results of this study revealed a high demand for this service among health-care providers.

Short- and long-term outcomes in infective endocarditis patients: a systematic review and meta-analysis

BackgroundDespite advances in medical knowledge, technology and antimicrobial therapy, infective endocarditis (IE) is still associated with devastating outcomes. No reviews have yet assessed the outcomes of IE patients undergoing short- and long-term outcome evaluation, such as all-cause mortality and IE-related complications. We conducted a systematic review and meta-analysis to examine the short- and long-term mortality, as well as IE-related complications in patients with definite IE.MethodsA computerized systematic literature search was carried out in PubMed, Scopus and Google Scholar from 2000 to August, 2016. Included studies were published studies in English that assessed short-and long-term mortality for adult IE patients. Pooled estimations with 95% confidence interval (CI) were calculated with DerSimonian-Laird (DL) random-effects model. Sensitivity and subgroup analyses were also performed. Publication bias was evaluated using inspection of funnel plots and statistical tests.ResultsTwenty five observational studies (retrospective, 14; prospective, 11) including 22,382 patients were identified. The overall pooled mortality estimates for IE patients who underwent short- and long-term follow-up were 20% (95% CI: 18.0–23.0, P < 0.01) and 37% (95% CI: 27.0–48.0, P < 0.01), respectively. The pooled prevalence of cardiac complications in patients with IE was found to be 39% (95%CI: 32.0–46.0) while septic embolism and renal complications accounted for 25% (95% CI: 20.0–31) and 19% (95% CI: 14.0–25.0) (all P < 0.01), respectively.ConclusionIrrespective of the follow-up period, a significantly higher mortality rate was reported in IE patients, and the burden of IE-related complications were immense. Further research is needed to assess the determinants of overall mortality in IE patients, as well as well-designed observational studies to conform our results.

Barriers and facilitators to hospital pharmacists’ engagement in medication safety activities: a qualitative study using the theoretical domains framework

BackgroundHospital pharmacists play a central role in medication safety activities. However, in Ethiopia, this role has been launched recently and little is known regarding the current status of this extended service. Using the Theoretical Domains Framework (TDF), we aimed to identify the barriers and facilitators to hospital pharmacists’ engagement in medication safety activities across various public hospitals in the Amhara region of Ethiopia.MethodsEight focus group discussions, using an interview guide that was drawn upon the TDF, were conducted with 44 hospital pharmacists to explore their beliefs regarding their involvement in clinical services. Group discussions were audio-recorded, transcribed verbatim, and analysed using directed content analysis based on the TDF. Relevant domains were identified by applying relevance criteria to each of the domains in the TDF.ResultsContent analysis revealed six domains that influence hospital pharmacists’ engagement in medication safety activities. These domains included ‘Knowledge’, ‘Skills’, ‘Environmental context and resources’, ‘Motivations and goals’, ‘Social influences’ and ‘Social/professional role’. Most hospital pharmacists believed knowledge gap was an issue, as was the lack of training and supportive skills although some expressed as they were competent enough for their skills in identifying medication related problems. Most participants were very much enthusiastic for their extended roles and were positive towards the future of the profession; however, competing priorities along with the lack of remuneration and awareness (of other health care professionals) regarding the profession’s role were barriers to service delivery. There were also a number of resource constraints, such as staffing, infrastructure and government funding, and acceptance rate of pharmacist’s recommendation that were likely to influence the clinical practice of pharmacists.ConclusionUsing the TDF, this study identified a wide range of barriers and facilitators to hospital pharmacists’ engagement in medication safety activities in resource-limited settings. There existed considerable interrelationships between domains that were perceived to influence hospital pharmacists’ behaviours, and this may assist in designing behaviour change interventions that target common behavioural domains.

Adverse Drug Events and Medication Errors in African Hospitals: A Systematic Review

BackgroundMedication errors and adverse drug events are universal problems contributing to patient harm but the magnitude of these problems in Africa remains unclear.ObjectiveThe objective of this study was to systematically investigate the literature on the extent of medication errors and adverse drug events, and the factors contributing to medication errors in African hospitals.MethodsWe searched PubMed, MEDLINE, EMBASE, Web of Science and Global Health databases from inception to 31 August, 2017 and hand searched the reference lists of included studies. Original research studies of any design published in English that investigated adverse drug events and/or medication errors in any patient population in the hospital setting in Africa were included. Descriptive statistics including median and interquartile range were presented.ResultsFifty-one studies were included; of these, 33 focused on medication errors, 15 on adverse drug events, and three studies focused on medication errors and adverse drug events. These studies were conducted in nine (of the 54) African countries. In any patient population, the median (interquartile range) percentage of patients reported to have experienced any suspected adverse drug event at hospital admission was 8.4% (4.5–20.1%), while adverse drug events causing admission were reported in 2.8% (0.7–6.4%) of patients but it was reported that a median of 43.5% (20.0–47.0%) of the adverse drug events were deemed preventable. Similarly, the median mortality rate attributed to adverse drug events was reported to be 0.1% (interquartile range 0.0–0.3%). The most commonly reported types of medication errors were prescribing errors, occurring in a median of 57.4% (interquartile range 22.8–72.8%) of all prescriptions and a median of 15.5% (interquartile range 7.5–50.6%) of the prescriptions evaluated had dosing problems. Major contributing factors for medication errors reported in these studies were individual practitioner factors (e.g. fatigue and inadequate knowledge/training) and environmental factors, such as workplace distraction and high workload.Conclusion Medication errors in the African healthcare setting are relatively common, and the impact of adverse drug events is substantial but many are preventable. This review supports the design and implementation of preventative strategies targeting the most likely contributing factors.
