Assessment of the implementation of pharmacist prescribing: Challenges and pathways for ambulatory practice

BACKGROUND

Prescribing by pharmacists is an increasingly common practice worldwide. In Brazil regulation of this practice began in 2013, and the practice remains unexplored as a research topic.

OBJECTIVE

We aimed to explore and gain insights into pharmacist prescribing practices in Brazil and assessing pharmacist's perceptions of their training and preparedness to prescribe medications.

METHODS

A cross-sectional survey was conducted between October 2022 and March 2023 via convenience sampling. Data were collected using an online questionnaire covering sociodemographic issues, academic training, prescribing practices, and perceptions regarding the provision of pharmacist prescribing in ambulatory care. Exploratory descriptive analysis and Poisson regression were performed to estimate the associations between pharmacist characteristics and their practices in prescribing medicines.

RESULTS

Among the 305 valid responses, 58.7% of the outpatient pharmacists stated that they had not prescribed any medication in the previous three years. Over-the-counter medication prescriptions were most common (42.0%). Only 4.6% of respondents had prescribed prescription-only medicines provided through collaborative agreement, with 2.6% reporting that they had adjusted doses, and 2.3% played a role in prescription renewal. Pharmacists living in Northeast regions tended to be more active prescribers (PR = 1.42; 95%CI 1.03-2.18), whereas those in primary healthcare (PR = 0.61; 95%CI 0.39-0.96) and self-declared Black pharmacists (PR = 0.30; 95%CI 0.10-0.97) prescribed less. Respondents strongly believed in the pharmacist's role as a prescriber, although they remained ambivalent regarding their responsibility for patient outcomes. Progress barriers include infrastructure gaps and strained relationships with physicians.

CONCLUSIONS

This study suggests that pharmacists in Brazil predominantly prescribe over-the-counter medications, and variations in setting, region, and race can influence prescribing by pharmacist in ambulatory care.

HTA criteria adopted in different models of public healthcare systems for orphan drugs: A scoping review

Access to drugs for rare diseases constitutes a challenge to healthcare systems, especially those with public funding. This study aimed to map and summarize the criteria used by HTA agencies in different healthcare systems to evaluate reimbursement recommendations for orphan drugs. A comprehensive literature search was performed on the databases PubMed, LILACS, Scopus, and Embase and the gray literature (Google Scholar and websites of HTA agencies). Publications addressing the criteria used by HTA agencies in countries with public healthcare systems when evaluating reimbursement recommendations for orphan drugs were included. This scoping review included 23 studies published between 2014 and 2023, mostly consisting of reviews of HTA reports, guidance documents, and original articles. The criteria were mapped from 19 countries and ranked within three models of healthcare systems (National Health System, National Health Insurance, and Social Health Insurance). All models shared concerns about unmet needs and disease nature. In addition, NHS countries (e.g., United Kingdom, Sweden, and Italy) prioritized innovation and system-level impact, while SHI countries (e.g., Germany, France, the Netherlands) usually valued budget impact and employed expedited evaluation processes. This review provides a comprehensive understanding of the general tendencies of each healthcare system model in establishing differentiated criteria to address the challenges posed by the limited evidence and investment in the field of rare diseases.

Towards inclusive healthcare: Pharmacists' perceptions on academic preparedness and healthcare provision for the LGBTQIA+ community

BACKGROUND

The community of lesbian, gay, bisexual, transgender, queer, intersex, asexual and other identities (LGBTQIA+), comprising sexual and gender minorities, frequently encounters violence, discrimination, and numerous obstacles in accessing healthcare services. Pharmacists have the potential to significantly contribute to the healthcare provision for this community.

OBJECTIVE

To assess pharmacists' perceptions regarding academic preparedness and healthcare provision for the LGBTQIA+ community in Brazil.

METHODS

An online cross-sectional survey was conducted from August 2022 to February 2023, focusing on the academic training of pharmacists and the provision of healthcare to the LGBTQIA+ community in Brazil. Data collection was achieved through a 28-question online questionnaire, comprising both closed-ended questions and Likert-type items. The study variables were subjected to an exploratory descriptive analysis.

RESULTS

We received 261 complete and valid responses. A majority of pharmacists indicated that they provided healthcare to the LGBTQIA+ community (n = 161, 61.7%); however, they lacked formal education on LGBTQIA+ healthcare during their pharmacy program (n = 256, 98.1%). Most participants strongly agreed that pharmacists play a crucial role in promoting healthcare for this community (n = 213, 81.6%). However, only a small percentage felt confident in addressing issues related to the effectiveness and safety of hormone use for transgender patients (n = 38, 14.6%). Furthermore, less than a third believed that the healthcare provided by pharmacists should be differentiated for patients within and outside of the LGBTQIA+ community (n = 76, 29.1%).

CONCLUSION

The results of this study underscore the necessity and significance of incorporating this topic both in pharmacy training and continuing education. This approach is crucial to enhance and bolster the clinical practice of pharmacists.

Pharmacists' contribution to benzodiazepine deprescribing in older outpatients: a systematic review and meta-analysis

BACKGROUND

Consolidated and reliable evidence regarding the effectiveness of pharmacist interventions for deprescribing benzodiazepines in older outpatients is lacking.

AIM

This study evaluated and summarized the impact of pharmacist interventions on benzodiazepine deprescribing among older outpatients.

METHOD

A literature search was conducted until August 2022 in PubMed, PsycINFO, and the Cochrane Central Register of Controlled Trials databases. The review included randomized controlled trials that assessed the impact of pharmacist interventions on deprescribing benzodiazepine in older outpatients. Two independent investigators conducted the study selection, data extraction, and risk of bias assessment. Meta-analyses were conducted using random-effect models in the RStudio software.

RESULTS

A total of 893 records were identified. Five studies, including 3,879 patients, met the inclusion criteria and were included in the systematic review. All five studies used health education as an intervention strategy, and three also conducted medication reviews. There was no evidence of the pharmacist's authority to modify prescriptions during benzodiazepine deprescribing. One study was classified as having a low risk of bias, whereas the other had some concerns or a high risk of bias. Three studies were included in the meta-analysis and a significant impact of pharmacist interventions on benzodiazepines deprescribing rates in older outpatients was observed (RR = 2.75 [95%CI 1.29; 5.89]; p = 0.04; I2 = 69%; low certainty of evidence).

CONCLUSION

Pharmacists may contribute to deprescribing benzodiazepines in older outpatients. Further studies are needed to increase the reliability of these findings. PROSPERO registration number: CRD42022358563.

Prevalence and incidence of depressive symptoms in pharmacy students: A systematic review

BACKGROUND

Pharmacy students are at high risk of developing depressive symptoms that can adversely influence their professional future. However, there are no summarized data on the subject.

OBJECTIVE

To summarize the prevalence and incidence of depressive symptoms in pharmacy students.

METHODS

A literature search was performed using PubMed, PsycINFO, CINAHL, LILACS, and SCOPUS databases until January 2022. We included observational studies that assessed the prevalence or incidence of depressive symptoms among pharmacy students using a validated screening instrument. Two independent investigators performed the study selection, data extraction, and quality assessment using the Joanna Briggs Institute (JBI) checklist for prevalence studies. The estimate of depressive symptoms was summarized as a narrative synthesis using structured tables.

RESULTS

Of the 695 records retrieved in the search, 19 studies met the eligibility criteria. All were cross-sectional studies, published between 2009 and 2022. The number of pharmacy students ranged from 30 to 610. Most studies were conducted in Asia (n = 9) and the Americas (n = 7), and included only public university students (n = 12). The studies used several instruments to screen students for depressive symptoms, mainly Patient Health Questionnaire-9 (n = 7), Beck Depression Inventory (n = 5), and Depression, Anxiety, and Stress Scale 21 (n = 4). Most studies (n = 15) evaluated only the prevalence of depressive symptoms. The estimate of overall, mild, moderate, and severe depressive symptoms ranged from 4.8% to 78.8%, 9.1% to 42.1%, 5.8% to 30.0%, and 0% to 50.0%, respectively. Regarding methodological quality, the score ranged from 4 to 7 out of 9 points according to the JBI checklist.

CONCLUSION

A high proportion of depressive symptoms were observed in pharmacy students. This finding points to the urgent need to develop strategies for screening, early identification of symptoms, and intervention to improve the mental health of students.

Evaluation of mobile applications focused on the care of patients with anxiety disorders: A systematic review in app stores in Brazil

OBJECTIVE

To identify and evaluate the quality of mobile apps available in Brazil focused on the care of patients with anxiety disorders.

METHODS

A comprehensive search was conducted until October 2021 on Play Store (Android) and Apple Store (iOS) in Brazil, using the terms "anxiety," "phobia," "panic attack," and "social phobia." Two independent authors identified the apps and performed data extraction and quality assessment using the Mobile App Rating Scale (MARS). Pearson's correlation was used to analyze the relationship between user star rating and the quality defined by the MARS instrument.

RESULTS

A total of 3,278 potential apps were identified, of which 71 fully met the eligibility criteria. Most apps were made available on the Play Store (91.74%), in English (69.01%), and updated in the last two years (90.14%). Approximately half of the apps (50.70%) did not inform the developer's country and most of them did not report the user star rating (70.42%). The target population was indicated as free by most apps (85.92%), with generalized anxiety disorder being the most addressed disorder (74.65%), followed by panic disorder (33.80%). The three main purposes of the apps were education (83.10%), self-assessment (38.03%), and meditation/breathing (32.39%). Only 31 apps (43.66%) had acceptable quality (above 3.0) and the average total MARS quality score of 2.93 (2.20 to 3.90), with the functionality section receiving the highest score (3.90) and the lowest scoring sections being engagement (2.16). The apps that were rated stars by users (29.58%) showed a negative Pearson correlation (ρ = -0.100), evidencing a difference in the user's evaluation and that performed using the MARS instrument.

CONCLUSION

Gaps in the quality of apps focused on the care of patients with anxiety disorders were evidenced since most were classified as having low quality through the MARS instrument. Thus, users are recommended to use these apps with caution.

[Does the pharmaceutical industry interfere in the sustainability of the public health system in Brazil? A reflection on the pressure for the incorporation of medicines]

The objective is to analyze the contribution of the pharmaceutical industry to the sustainability of the Brazilian Unified National Health System (SUS), based on the pressure for the incorporation of medicines. For this purpose, a descriptive study was conducted on requests for the incorporation of medicines sent to Commission for Incorporation of Technologies in the SUS (CONITEC) from 2012 to 2020. Characteristics such as technology indication, economic evaluation, financing component, public consultation, and CONITEC decision were analyzed. The results were compared according to the type of solicitor using statistical tests. 514 requests were analyzed, of which 438 related to incorporation. The pharmaceutical industry accounted for 37% of the requests and 33.5% of the incorporations. Differences were observed between the solicitors regarding the type of economic evaluation and incremental cost-utility ratio value, with half of the industry's demands above the threshold of 3 PIB per capita/QALY. The pharmaceutical industry obtained more contributions in public consultations of its requests and presented concentration of requests for antineoplastic and immunomodulatory agents and for anti-infectious, especially for hepatitis C and HIV. There was also a lower number of demands from the pharmaceutical industry in the Basic and Strategic Components of Pharmaceutical Assistance. Our findings point to the tension between the significant participation of the industry as an applicant, the high mobilization of public consultations, the emphasis on Specialized Component drugs, and CONITEC's resistance to this pressure, with a tendency of greater refusal and greater participation of other solicitors in requests for expansion of use, exclusion, and incorporation of drugs that are less requested by the pharmaceutical industry.

Interface entre a saúde mental de crianças e adolescentes e a atuação clínica do farmacêutico: um estudo qualitativo

O estudo objetivou analisar a percepção do farmacêutico sobre a sua atuação clínica em Centros de Atenção Psicossocial Infantojuvenil (CAPSi). Foi realizado estudo qualitativo, por meio de entrevistas on-line individuais e semiestruturadas com seis farmacêuticas de CAPSi. As entrevistas foram gravadas, transcritas, analisadas e categorizadas segundo o método de análise de conteúdo. As categorias temáticas foram “Equipe multidisciplinar e as diferentes formas de produção de cuidado”, “Inserção do farmacêutico no serviço”, “Aspectos que se relacionam ao uso de psicofármacos” e “Nuances do trabalho farmacêutico em rede na infância e adolescência”. Os resultados mostram uma gradual mudança de paradigma da atuação do farmacêutico em direção ao cuidado da pessoa em sofrimento mental, culminando em ampla atuação na equipe multidisciplinar. Apesar disso, foi apontada a necessidade de documentos que guiem a atuação clínica deste profissional com o público infantojuvenil.

Incorporation of drugs for rare diseases in Brazil: is it possible to have full access to these patients?

This study aims to describe the profile for the requested incorporation of rare disease drugs submitted to CONITEC and its recommendations, comparing the incorporation criteria employed by other HTA agencies globally. To this end, requests for the treatment of rare diseases submitted to CONITEC from July 2012 to June 2019 and its recommendations to the Brazilian Unified Health System (SUS) were included in this study. Subsequently, we compared the criteria used by CONITEC and other HTA agencies to incorporate these drugs. Sixty medicine incorporation requests to treat thirty rare diseases were submitted to CONITEC. Pharmaceutical companies made the most requests (66%). Budget impact analyses were presented in 85% of the requests and HT economic analyses in 68%. A total of 52% of the requests were incorporated into the SUS. CONITEC's justifications for the non-incorporation were the lack of quality clinical evidence, non-cost-effective technologies, and modest clinical benefits that do not justify the high prices. International HTA agencies (CAN, UK, FR, AUS) use different criteria for rare diseases assessments. The data indicate that most of the evaluated drugs were incorporated into the SUS, and adopting different criteria to assess the incorporation of rare diseases medicines will possibly strengthen decision-making.

Use of medications by patients who are Deaf or Hard of Hearing: Reflections for the promotion of rational use

BACKGROUND

Pharmacists are often unable to maintain satisfactory communication with people who are Deaf or Hard of Hearing (DHoH), potentially exposing those who are DHoH to various risks related to the use of medications.

OBJECTIVE

To evaluate the use of medications, knowledge on their rational use, and communication with the pharmacist during the dispensing of medications among people who are DHoH.

METHODS

A pilot cross-sectional study was conducted between February 2020 and May 2020 among those who are DHoH in Brazil. Data were collected using an online questionnaire about sociodemographic and clinical characteristics, the use of medications, knowledge on the rational use of medications, and communication with the pharmacist during dispensing. The questionnaire was developed in Brazilian sign language.

RESULTS

Twenty-one responses were obtained. The mean age of the respondents was 31.9 years, 67% were women, and 38% had cochlear implants. The most used medications were analgesics (22.2%) and anti-inflammatory and antirheumatic drugs (14.3%). The responses to the 20 statements on the rational use of medications resulted in a mean of 12.6 correct responses per individual. Almost all participants provided correct responses to the statements about medication intake times and expiration dates of medications. Only 33.3% of the patients responded that they would approach the pharmacist if they had questions regarding the medications. Most of the participants were dissatisfied with pharmacist counseling during the dispensing of medications.

CONCLUSION

This study revealed an important reflection on possible self-medication by patients who are DHoH, poor knowledge on the rational use of medications, and dissatisfaction with pharmacist counseling during the dispensing of medications.

Factors Associated With Use of Medications for Anxiety and Depression in Pharmacy Students in Brazil

Objective. To map undergraduate pharmacy students' use of medications for anxiety and depression and associated factors at one university in Brazil.Methods. A cross-sectional study was conducted from May to July 2019 among undergraduate pharmacy students at one university. Data regarding sociodemographic issues and the use of psychotropics were collected using an online questionnaire. Exploratory descriptive analysis of data, the chi-square test, and multivariate binary logistic regression were performed to identify factors associated with the use of medications for anxiety and depression.Results. Of 900 students enrolled, usable survey responses were received from 198. Most respondents were female with a mean age of 22.3 years. Among these, 17.7% of pharmacy students used medications to treat anxiety and 13.1% used medications for depression. The most common psychotropics were escitalopram and fluoxetine. There were two peak usage times: the initial and final year of pharmacy school. Dissatisfaction with the pharmacy program and psychological care were significantly associated with the use of medications for anxiety. In contrast, monthly income from three to 15 times the minimum wage, religiosity/spirituality, and psychological care were associated with students' use of medications for depression.Conclusion. There was a high prevalence of medication use to treat anxiety and depression among undergraduate pharmacy students, and this use was associated with psychological care, monthly income, and religiosity/spirituality.

Association Between Intra-Hospital Uncontrolled Glycemia and Health Outcomes in Patients with Diabetes: A Systematic Review of Observational Studies

BACKGROUND

Many people are still getting affected by uncontrolled glycemic events during hospital admission, which encompasses hypoglycemia, hyperglycemia, and high glycemic variability.

INTRODUCTION

Primary studies have shown an association of glycemic dysregulation with increased length of hospital stay and mortality among overall patients, however, there is no systematic review of current evidence on the association between uncontrolled in-hospital glycemia in patients with diabetes and health outcomes. This study aimed to systematically review the current evidence on the association between uncontrolled in-hospital glycemia in patients with diabetes and health outcomes.

METHODS

The association between glycemic dysregulation and health outcomes for inpatients with diabetes was systematically reviewed. PubMed, Embase, and LILACS databases were searched. Two independent reviewers were involved in each of the following steps: screening titles, abstracts, and fulltexts; assessing the methodological quality; and extracting data from included reviews. Descriptive analysis method was used.

RESULTS

Seven cohort studies were included, and only two had a prospective design, consisting of 7,174 hospitalized patients with diabetes. In-hospital occurrence of hypoglycemia, hyperglycemia, and glycemic variability were assessed, and outcomes were mortality, infections, renal complications, and adverse events. Among the exposure and outcomes, an association was observed between severe hypoglycemia and mortality, hyperglycemia and infection, and hyperglycemia and adverse events.

CONCLUSION

In-hospital uncontrolled glycemia in patients with diabetes is associated with poor health outcomes. More studies should be conducted for proper investigation because diabetes is a complex condition. Effects of glycemic dysregulation should be investigated on the basis of overall health of a patient instead from only organ-target perspective, which makes the investigation difficult.

Economic evaluations on the use of aripiprazole for patients with schizophrenia: A systematic review

WHAT IS KNOWN AND OBJECTIVES

Schizophrenia is a serious mental disorder and is associated with substantial economic and social burden. Cost-effectiveness analysis is important to assess the costs of different therapeutic options. However, there is a lack of information on the reporting quality of economic evaluations, cost drivers, as well as updated data focused on aripiprazole, an antipsychotic drug commonly prescribed in schizophrenia. This study evaluates and summarizes the evidence of economic evaluations of the use of aripiprazole in schizophrenia. In addition, we aimed to identify cost drivers and critically assess the reporting qualities of these studies.

METHODS

A comprehensive literature research was conducted using PubMed, NHS Economic Evaluation Database, CEA Registry and LILACS databases dated until March 2018. Full economic analyses of aripiprazole in schizophrenia that were based on decision analytical models and published in English, Portuguese or Spanish languages were included. Two independent authors identified the studies and performed data extraction and quality assessment using 24 items from the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement.

RESULTS AND DISCUSSION

A total of 79 potential studies were identified, of which 17 studies performing model-based economic evaluations fully met the eligibility criteria. Of these, 15 were industry-funded studies. A trend favouring olanzapine, lurasidone and paliperidone could be observed, whereas aripiprazole was extensively described as a dominated alternative. However, notably, 93% of the industry-funded studies presented results favouring their sponsors, only two of them being the manufacturer of aripiprazole. Cost drivers were usually related to the relapse rates/probabilities regardless of the funding source. The overall quality of reporting of the economic analyses was poor, with most studies scoring around 12-13 points. The most frequent problems were the lack of description of relevance of the outcome measures, characteristics of the base case population and report of precision measures for all the parameters of the model.

WHAT IS NEW AND CONCLUSION

No consistent conclusion on the cost-effectiveness of aripiprazole could be drawn due to the context-specific costs, conflicting parameters of effectiveness and safety, and bias related to industry sponsorship. Cost drivers, though, were usually related to the relapse rates/probabilities. In addition, poor reporting quality of the studies performing full economic analysis requires further improvement to ensure greater transparency of the findings.

Development and validation of key performance indicators for medication management services provided for outpatients

BACKGROUND

One of the elements of quality improvement of medication management services is measuring the quality of care and key performance indicators (KPIs) can be used in this assessment. There has been no publishing yet about a KPI instrument developed for ambulatory setting.

OBJECTIVES

To develop and validate KPI instrument for medication management services provided for outpatients in Brazilian context.

METHODS

A working group established 7 possible KPIs for assessment of the expert panel. For content validity, 16 experts were invited to participate in an internet based 2-round Delphi approach. Expert panel rated 7 possible KPIs using 7 attributes on a 5-point Likert scale for consensus. In order to construct validity and reliability, an internet questionnaire was developed for pharmacists that work in primary care to understand their views. In addition, a comparison between expert and pharmacist views about the indicators relevance was performed.

RESULTS

Eleven (68.8%) experts participated in the Delphi round 1 and nine (81.8%) experts completed the 2 Delphi rounds. A new KPI was develop after expert panel assessment in the first round. Overall, content and construct validity were reached for 6 KPIs: pharmaceutical consultation provided (I₁), pharmacist interventions accepted by the prescriber (I₂), drug therapy problems resolved (I₃), patient clinical status (I₄), patient satisfaction (I₅), and patient quality of life (I₆).

CONCLUSIONS

A set of 6 KPIs was developed for medication management services provided for outpatients. The instrument presented a good reliability and validity evidence. It is expected that these KPIs will improve the quality of medication management services.

Pharmacist-Patient Communication in Prostate Cancer as a Strategy to Humanize Health Care: A Qualitative Study

Background:

Pharmacists require effective communication skills to enhance involvement in patient care. Nevertheless, there are few qualitative studies exploring “how” pharmacist–patient communication occurs and none targets patients with cancer.

Objective:

To describe the perceptions of outpatients with prostate cancer regarding the communication process during clinical pharmacy service in a community pharmacy.

Methods:

A qualitative study was performed from semistructured interviews with 10 patients. These interviews were audiotape-recorded and transcribed comprehensively, and the data were analyzed using content analysis. The validation of the categories and registration units was made by 2 independent authors and reviewed by a third author.

Results:

Three categories were established from the content analysis (general perceptions of the pharmacist–patient communication, potentialities of effective communication, and points for improvement). Communication is a complex process and involves, in addition to information exchange, the sharing of thoughts, desires, and fears. Our findings hold that effective communication skills by pharmacist can help patients validate their concerns, develop a trusting patient–pharmacist relationship, address drug therapy problems, and lead to better health outcomes.

Conclusion:

Pharmacist–patient communication is an important strategy for humanized practice. This allows the pharmacist to see beyond an individual with health problems to a human being with particularized needs.

Efficacy and safety of aripiprazole for the treatment of schizophrenia: an overview of systematic reviews

PURPOSE

To conduct an overview to summarize the efficacy and safety of aripiprazole for the treatment of schizophrenia.

METHODS

A literature search was performed in PubMed, the Cochrane Library, LILACS, and the Centre for Reviews and Dissemination, for articles published until March 31, 2017. We included systematic reviews with meta-analyses of randomized controlled trials assessing the efficacy, and/or the safety of aripiprazole, for patients with schizophrenia. Two authors independently performed the study selection, data extraction, and quality assessment. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach and the Risk of Bias in Systematic Review (ROBIS) tool were used to appraise the quality of evidence and the risk of bias in the reviews, respectively.

RESULTS

Fourteen studies fulfilled the inclusion criteria. Aripiprazole showed efficacy similar to that of both typical and atypical antipsychotic drugs (except olanzapine and amisulpride). Aripiprazole caused significantly lower weight gain and alterations in glucose and cholesterol levels, as compared to clozapine, risperidone, and olanzapine. In addition, aripiprazole caused significantly fewer general extrapyramidal side effects, less use of antiparkinsonian drugs, and akathisia, compared with typical antipsychotic drugs and risperidone. The overall quality of evidence in the reviews ranged from "very low" to "moderate," principally because of the risk of bias of original trials, inconsistency, and imprecision in the outcomes. According to the ROBIS tool, there are four reviews with "high" risk of bias and five with "unclear" risk of bias.

CONCLUSIONS

Aripiprazole exhibited efficacy similar to that of other antipsychotic drugs and a better safety profile than that of typical (i.e., less some extrapyramidal side effects) and atypical (i.e., less metabolic changes) antipsychotic drugs.

Potentially inappropriate prescribing and associated factors in elderly patients at hospital discharge in Brazil: a cross-sectional study

Background The Screening Tool of Older Persons' Prescriptions/Screening Tool to Alert doctors to Right Treatment (STOPP/START) criteria is used to identify instances of potentially inappropriate prescribing in a patient's medication regimen. Objective To determine the prevalence and predictors of potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs) among elderly patients at hospital discharge. Setting A university hospital medical clinic in Brazil. Method Discharge prescriptions were examined using the STOPP/START criteria. Subjects were inpatients aged ≥60 years receiving at least one medication prior to hospitalization and with a history of cardiovascular disease. The prevalence of PIMs and PPOs was determined and a multivariable binary regression analysis was performed to identify independent predictors associated with PIMs or PPOs. Main outcome measure Prevalence of PIMs and PPOs. Results Of the 230 subjects, 13.9% were prescribed at least one PIM. The most frequently prescribed PIMs were glibenclamide or chlorpropamide prescribed for type 2 diabetes mellitus (31.0%), and aspirin at doses >150 mg/day (14.3%). Ninety patients had at least one PPO (39.1%). The most prevalent PPOs were statins (29.8%) and antiplatelet therapy (13.7%) for diabetes mellitus when coexisting major cardiovascular risk factors were present. No predictors for PIMs were found. In contrast, diabetes was a risk factor while dyslipidaemia was a protective factor for PPOs. Conclusion PIMs and PPOs commonly occur with elderly people at hospital discharge. Diabetes and dyslipidaemia were significantly associated with PPOs. Our findings show the need for interventions to reduce potentially inappropriate prescribing, such as a pharmacist medication review process at hospital discharge.

Investigating Sources of Heterogeneity in Randomized Controlled Trials of the Effects of Pharmacist Interventions on Glycemic Control in Type 2 Diabetic Patients: A Systematic Review and Meta-Analysis

OBJECTIVE

To assess the effect of pharmacist interventions on glycemic control in type 2 diabetic patients and to examine factors that could explain the variation across studies.

METHODS

A comprehensive literature search was performed in PubMed, Scopus, and LILACS databases for randomized controlled trials (RCTs) published up to July 2015. The search strategy included the use of MeSH terms or text words related to pharmacist interventions, type 2 diabetes, and randomized controlled trials. RCTs published in English, Portuguese, or Spanish that evaluated the effect of pharmacist intervention on glycemic control in type 2 diabetic outpatients were included. Two independent authors executed study selection, data extraction, and risk of bias assessment. Mean differences in glycosylated hemoglobin (HbA1c) were estimated using random-effect models, and heterogeneity was evaluated by subgroup and meta-regression analyses.

RESULTS

The literature search yielded 963 records of potential interest, of which 30 were included in the systematic review and 22 in the meta-analysis. Most of these RCTs were conducted in the United States in patients in outpatient clinics using face-to-face contact only. All RCTs performed patient education, and most executed the medication review. The appraised sample showed uncertain or high risk of bias in most of the items evaluated, resulting in low-quality studies. In comparison with usual care, pharmacist interventions were associated with significant reductions in HbA1c levels (-8.5% [95% CI: -1.06, -0.65]; P < 0.0001; I2 = 67.3%). Subgroup analysis indicated differences of heterogeneity by country, baseline HbA1c levels, setting, intervention frequency, and random allocation. Age and HbA1c levels partly explained the variability across studies by meta-regression.

CONCLUSIONS

Our findings confirmed that pharmacist interventions improve glycemic control in patients with type 2 diabetes compared with usual care and suggest that younger patients or with higher baseline HbA1c levels may be the main beneficiaries of pharmacist care.

[The role of the pharmacist in dispensing medication in Adult Psychosocial Care Centers in the city of São Paulo, Capital of the State of São Paulo, Brazil]

The objective of this study was to evaluate the role of the pharmacist in dispensing medication by conducting cross-sectional exploratory-descriptive research in eight Adult Psychosocial Care Centers (CAPS) in São Paulo. The pharmacists responsible for each of the dispensing units studied filled out a semi-structured questionnaire about the service provided. Two Adult CAPS units were selected from each of the North, South, Eastand West regions of São Paulo. The central region has no Adult CAPS, and was therefore not included in the study. Most of the respondents were aged between 35 and 40 years and were predominantly female. It was found that half of the respondents performed only 25% of dispensations and few conducted an analysis of all prescriptions before dispensing medication. All respondents contacted the prescriber if any medication-related problems a rose. However, few pharmaceutical interventions were commonly performed. Furthermore, one respondent indicated that all his/her functions in the pharmacy could be delegated to another professional. These findings reveal the pressing need for actions that ensure the ongoing training of pharmacists to enable them to be clinically prepared to deal with patients with mental disorders.

Exploring the Quality of Systematic Reviews on Pharmacist Interventions in Patients With Diabetes: An Overview

OBJECTIVE

To assess the reporting and methodological quality of systematic reviews and meta-analysis studies on pharmacist interventions in patients with diabetes.

DATA SOURCES

A comprehensive literature search was performed in MEDLINE, Scopus, and LILACS databases for systematic reviews and meta-analysis studies published from January 1990 to June 2013. The standardized search strategy included the use of MeSH terms or text words related to pharmacist interventions, diabetes, and systematic reviews.

STUDY SELECTION AND DATA EXTRACTION

The overview included systematic reviews and meta-analysis studies published in English, Portuguese, or Spanish that evaluated the effect of pharmacist intervention on outcomes for diabetic patients. Two independent authors performed study selection, data extraction, and quality assessment with a consensus process to address disagreements. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) and Assessment of Multiple Systematic Reviews (AMSTAR) checklists were used to assess reporting characteristics and methodological quality, respectively.

DATA SYNTHESIS

The literature search yielded 101 records of potential interest, of which 7 satisfied the inclusion criteria. The total average (SD) for PRISMA and AMSTAR scores were 17.4 (5.6) out of 27 and 6.9 (2.0) out of 11, respectively. The most frequent problems included nonregistration of study protocol, absence of a list of excluded studies, and unclear acknowledgment of conflicts of interests.

CONCLUSION

The reporting and methodological quality of systematic reviews and meta-analysis studies were suboptimal, with some areas needing further improvement. It is necessary to ensure better transparency and reproducibility in the literature of clinical pharmacy services for diabetic patients.

Motor performance after posteroventral pallidotomy and VIM-thalamotomy in Parkinson's disease: a 1-year follow-up study

Twenty-three patients with Parkinson's disease underwent stereotactic surgery. To study the long-term motor performance, the patients were evaluated at the pre-operative period and at the 1st, 3rd, 6th, and 12th post-operative months, with the following scales: Unified Parkinson's Disease Rating Scale (UPDRS) motor score and Larsen's Scale for Dyskinesias. The patients under levodopa therapy were assessed both in "on" and "off" periods. Fourteen unilateral ventrolateral thalamotomies (VLT), 4 unilateral posteroventral pallidotomies (PVP), 2 bilateral PVP, and 3 VLT with contralateral PVP were performed. The motor improvement was significant and long-lasting in the "off" period, except for 2 patients. The "on" period quality improved, mainly due to the control of dyskinesias. The improvement of dyskinesias was long-lasting for the majority of the patients. There was no significant decrease in the levodopa dose. Three patients showed permanent complications, but none was severe.

[Stereotaxic thalamotomy and pallidotomy with computerized planning in Parkinson's disease: short-term evaluation of motor function in 50 patients]

We evaluated the motor function of 50 patients with Parkinson's disease, who underwent stereotaxic surgery with computerized planning, without ventriculography (ventrolateral thalamotomy- VLT- and/or posteroventral pallidotomy- PVP) before and one month after surgery. 27 unilateral TVL, 10 unilateral PVP, 6 bilateral PVP, and 7 TVL with PVP were performed. The motor evaluation was performed with the Unified Parkinson's Disease Rating Scale, motor score, during on and off periods. We observed a global motor improvement in all groups. The improvement of dyskinesias was obtained in the contralateral side of the body, in the PVP groups. From the 50 patients, 16 (32%) presented post-operative complications, 9 of these (56.25%) improved completely, 6 (37.25%) improved partially, and 1 (6.25%) did not improve during the first month. These results were considered satisfactory, and a long term analysis will show whether these benefits are long lasting or not.
