Development and Implementation of a Decision Support System to Improve Control of Hypertension and Diabetes in a Resource-Constrained Area in Brazil: Mixed Methods Study.

BACKGROUND: The low levels of control of hypertension and diabetes mellitus are a challenge that requires innovative strategies to surpass barriers of low sources, distance, and quality of health care. OBJECTIVE: The aim of this study is to develop a clinical decision support system (CDSS) for diabetes and hypertension management in primary care, to implement it in a resource-constrained region, and to evaluate its usability and health care practitioner satisfaction. METHODS: This mixed methods study is a substudy of HealthRise Brazil Project, a multinational study designed to implement pilot programs to improve screening, diagnosis, management, and control of hypertension and diabetes among underserved communities. Following the identification of gaps in usual care, a team of clinicians established the software functional requirements. Recommendations from evidence-based guidelines were reviewed and organized into a decision algorithm, which bases the CDSS reminders and suggestions. Following pretesting and expert panel assessment, pilot testing was conducted in a quasi-experimental study, which included 34 primary care units of 10 municipalities in a resource-constrained area in Brazil. A Likert-scale questionnaire evaluating perceived feasibility, usability, and utility of the application and professionals' satisfaction was applied after 6 months. In the end-line assessment, 2 focus groups with primary care physicians and nurses were performed. RESULTS: A total of 159 reminders and suggestions were created and implemented for the CDSS. At the 6-month assessment, there were 1939 patients registered in the application database and 2160 consultations were performed by primary care teams. Of the 96 health care professionals who were invited for the usability assessment, 26% (25/96) were physicians, 46% (44/96) were nurses, and 28% (27/96) were other health professionals. The questionnaire included 24 items on impressions of feasibility, usability, utility, and satisfaction, and presented global Cronbach α of .93. As for feasibility, all professionals agreed (median scores of 4 or 5) that the application could be used in primary care settings and it could be easily incorporated in work routines, but physicians claimed that the application might have caused significant delays in daily routines. As for usability, overall evaluation was good and it was claimed that the application was easy to understand and use. All professionals agreed that the application was useful (score 4 or 5) to promote prevention, assist treatment, and might improve patient care, and they were overall satisfied with the application (median scores between 4 and 5). In the end-line assessment, there were 4211 patients (94.82% [3993/4211] with hypertension and 24.41% [1028/4211] with diabetes) registered in the application's database and 7960 consultations were performed by primary health care teams. The 17 participants of the focus groups were consistent to affirm they were very satisfied with the CDSS. CONCLUSIONS: The CDSS was applicable in the context of primary health care settings in low-income regions, with good user satisfaction and potential to improve adherence to evidence-based practices.

Impact of telemedicine interventions on mortality in patients with acute myocardial infarction: a systematic review and meta-analysis.

BACKGROUND: Despite the promise of telemedicine to improve care for ischaemic heart disease, there are significant obstacles to implementation. Demonstrating improvement in patient-centred outcomes is important to support development of these innovative strategies. OBJECTIVE: To assess the impact of telemedicine interventions on mortality after acute myocardial infarction (AMI). METHODS: Articles were searched in MEDLINE, Cochrane Central Register of Controlled Trials, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), Base de Dados de Enfermagem (BDENF), Indice Bibliográfico Español en Ciencias de la Salud (IBECs), Web of Science, Scopus and Google Scholar, from January 2004 to January 2018. Study selection and data extraction were performed by two independent reviewers. In-hospital mortality (primary outcome), and door-to-balloon (DTB) time, 30-day mortality and long-term mortality (secondary outcomes) were assessed. Random effects models were applied to estimate pooled results. RESULTS: Thirty non-randomised controlled and seven quasi-experimental studies were included (16 960 patients). They were classified as moderate or serious risk of bias by ROBINS-I (Risk Of Bias In Non-randomized Studies-of Interventions tool). In 31 studies, the intervention was prehospital ECG transmission. Telemedicine was associated with reduced in-hospital mortality compared with usual care (relative risk (RR) 0.63(95% confidence interval[CI] 0.55 to 0.72); I2 <0.001%). DTB time was consistently reduced (mean difference -28 (95% CI -35 to -20) min), but showed large heterogeneity (I2=94%). Thirty-day mortality (RR 0.62;95% CI 0.43 to 0.85) and long-term mortality (RR 0.61(95% CI 0.40 to 0.92)) were also reduced, with moderate heterogeneity (I2=52%). CONCLUSIONS: There is moderate-quality evidence that telemedicine strategies, in particular ECG transmission, combined with the usual care for AMI are associated with reduced in-hospital mortality and very-low quality evidence that they reduce DTB time, 30-day mortality and long-term mortality.

The Impact of mHealth Interventions: Systematic Review of Systematic Reviews.

BACKGROUND: Mobile phone usage has been rapidly increasing worldwide. mHealth could efficiently deliver high-quality health care, but the evidence supporting its current effectiveness is still mixed. OBJECTIVE: We performed a systematic review of systematic reviews to assess the impact or effectiveness of mobile health (mHealth) interventions in different health conditions and in the processes of health care service delivery. METHODS: We used a common search strategy of five major scientific databases, restricting the search by publication date, language, and parameters in methodology and content. Methodological quality was evaluated using the Measurement Tool to Assess Systematic Reviews (AMSTAR) checklist. RESULTS: The searches resulted in a total of 10,689 articles. Of these, 23 systematic reviews (371 studies; more than 79,665 patients) were included. Seventeen reviews included studies performed in low- and middle-income countries. The studies used diverse mHealth interventions, most frequently text messaging (short message service, SMS) applied to different purposes (reminder, alert, education, motivation, prevention). Ten reviews were rated as low quality (AMSTAR score 0-4), seven were rated as moderate quality (AMSTAR score 5-8), and six were categorized as high quality (AMSTAR score 9-11). A beneficial impact of mHealth was observed in chronic disease management, showing improvement in symptoms and peak flow variability in asthma patients, reducing hospitalizations and improving forced expiratory volume in 1 second; improving chronic pulmonary diseases symptoms; improving heart failure symptoms, reducing deaths and hospitalization; improving glycemic control in diabetes patients; improving blood pressure in hypertensive patients; and reducing weight in overweight and obese patients. Studies also showed a positive impact of SMS reminders in improving attendance rates, with a similar impact to phone call reminders at reduced cost, and improved adherence to tuberculosis and human immunodeficiency virus therapy in some scenarios, with evidence of decrease of viral load. CONCLUSIONS: Although mHealth is growing in popularity, the evidence for efficacy is still limited. In general, the methodological quality of the studies included in the systematic reviews is low. For some fields, its impact is not evident, the results are mixed, or no long-term studies exist. Exceptions include the moderate quality evidence of improvement in asthma patients, attendance rates, and increased smoking abstinence rates. Most studies were performed in high-income countries, implying that mHealth is still at an early stage of development in low-income countries.

Implementação de oficinas educacionais em uma clínica de anticoagulação / Employment of educational workshops as an anticoagulation clinic

Ao entender que práticas educacionais podem contribuir para melhores resultados nos processos de cuidado em saúde, o presente artigo possui o objetivo de descrever a experiência da implementação de oficinas como estratégia educacional em uma clínica de anticoagulação de um hospital geral. A execução das oficinas consistiu na dinâmica em grupo e na utilização de recursos visuais. Essa prática foi subdividida nas temáticas "conhecendo o problema de saúde", "uso correto da varfarina", "alimentação e anticoagulação" e "conhecendo o corpo". A descrição da experiência ocorreu por meio de análise observacional, gravação dos encontros e análise das falas por meio da técnica de análise de conteúdo. Participaram das oficinas 19 pacientes em uso de varfarina e sete acompanhantes. Identificaram-se duas categorias: na "sistematização do fazer", identificou-se que o processo de cuidado ocorre de forma médico-centrada, sem a valorização do paciente como sujeito em ato, e na "redescobrindo-se no tratamento", os participantes foram capazes de redimensionar o processo de cuidado e construir um novo olhar sobre sua participação nesse processo. As oficinas propiciaram para os participantes uma troca de experiências e dúvidas, podendo contribuir para uma maior compreensão do problema de saúde e tratamento, além de propiciar aos profissionais melhor compreensão sobre a experiência dos pacientes em relação ao tratamento.

Educational initiatives focused on improving the understanding of anticoagulant therapy by the patient can improve treatment outcomes. We aimed to describe the planning stages and achievements of workshops as an educational strategy in an anticoagulation clinic of a general hospital. The following two phases were involved: the determination of the issues of approach by conducting focus groups; and the performance of workshops, consisting of dynamics of group and visuals. Methods of observational analysis, recording of meetings and content analysis were employed. Nineteen patients on warfarin and seven caregivers participated of the workshops. The following items were identified as topics of approach: "knowing the health problem", "correct use of warfarin", "food and anticoagulation" and "knowing the body". An effect of obedience associated with anticoagulant treatment was observed, mainly in the need of self-care, control of eating habits and the importance of adherence. The workshops as educational strategy provide an exchange of experiences and questions, which may contribute to a greater understanding of the health problem and treatment, with consequent improvement in adherence to pharmacotherapy.
