HBA1C point-of-care testing for diabetes control in a low-income population: A before and after study and cost-parity analysis HbA1c point-of-care testing for diabetes control.

OBJECTIVE: To evaluate the results of a program that offered access to HbA1c POC tests for the glycemic control of patients with diabetes in small and poor municipalities of Minas Gerais, Brazil. METHODS: Using a before and after study, we compared four groups: patients submitted to (i) POC tests; (ii) conventional tests; (iii) both tests; and (iv) neither test. The analysis considered three periods: before the program; before the pandemic; and during the pandemic. A cost comparison was conducted under the societal perspective and a cost-parity model was designed. RESULTS: 1349 patients previously diagnosed with diabetes were included in the analysis. The rate of consultations and the rate of HbA1c testing were significantly different between all periods and groups. Group iii had a much higher consultation and testing rate. The costs were around 89.45 PPP-USD for POC tests and between 32.44 and 54.66 PPP-USD for conventional tests. Cost-parity analysis suggests that the technology would be acceptable if the annual number of tests was between 247 and 771. CONCLUSION: Using POC devices improved access to HbA1c testing but not glycemic control. Even in small towns, the number of tests necessary to achieve cost-parity is low enough to enable their incorporation into the public health system.

The Challenges of Implementing a Text Message Intervention to Promote Behavioral Change in Primary Care Patients With Hypertension and Diabetes

Abstract Background Controlling blood pressure and glycemic levels is a challenge that requires innovative solutions. Objective To assess the feasibility of implementing a text message intervention among low-income primary care patients, as well as to assess self-reported behavioral change. Methods A set of 200 text messages was developed on healthy eating, physical activity, adherence, and motivation. Participants from Vale do Mucuri, MG, Brazil diagnosed with diabetes or hypertension or undergoing screening for those diseases, received 5 to 8 messages per week for 6 months. They answered a questionnaire to report their satisfaction and behavioral changes. Results Of the 136 patients, 117 (86.0%) answered the questionnaire. Most reported that the messages were very useful (86.3%), easy to understand (90.6%), and were very helpful for behavioral change (65.0%); 84.6% reported that they had started eating healthier. The most frequent reported lifestyle changes were: improved diet quality (85.5%), reduced portions (65.8%), and weight loss (56.4%). The majority of patients shared the messages (60.7%) with family or other acquaintances, considered the number of messages to be adequate (89.7%) and would recommend the program to others (95.7%). Conclusion An intervention based on text messages to promote behavioral change in patients with hypertension or diabetes in primary care is feasible in low-resource settings. Future studies are needed to assess the program's long-term effects on clinical outcomes.

Pandemic-Related Impairment in the Monitoring of Patients With Hypertension and Diabetes and the Development of a Digital Solution for the Community Health Worker: Quasiexperimental and Implementation Study.

BACKGROUND: The restrictions imposed by the COVID-19 pandemic reduced health service access by patients with chronic diseases. The discontinuity of care is a cause of great concern, mainly in vulnerable regions. OBJECTIVE: This study aimed to assess the impact of the COVID-19 pandemic on people with hypertension and diabetes mellitus (DM) regarding the frequency of consultations and whether their disease was kept under control. The study also aimed to develop and implement a digital solution to improve monitoring at home. METHODS: This is a multimethodological study. A quasiexperimental evaluation assessed the impact of the pandemic on the frequency of consultations and control of patients with hypertension and DM in 34 primary health care centers in 10 municipalities. Then, an implementation study developed an app with a decision support system (DSS) for community health workers (CHWs) to identify and address at-risk patients with uncontrolled hypertension or DM. An expert panel assessment evaluated feasibility, usability, and utility of the software. RESULTS: Of 5070 patients, 4810 (94.87%) had hypertension, 1371 (27.04%) had DM, and 1111 (21.91%) had both diseases. There was a significant reduction in the weekly number of consultations (107, IQR 60.0-153.0 before vs 20.0, IQR 7.0-29.0 after social restriction; P<.001). Only 15.23% (772/5070) of all patients returned for a consultation during the pandemic. Individuals with hypertension had lower systolic (120.0, IQR 120.0-140.0 mm Hg) and diastolic (80.0, IQR 80.0-80.0 mm Hg) blood pressure than those who did not return (130.0, IQR 120.0-140.0 mm Hg and 80.0, IQR 80.0-90.0 mm Hg, respectively; P<.001). Also, those who returned had a higher proportion of controlled hypertension (64.3% vs 52.8%). For DM, there were no differences in glycohemoglobin levels. Concerning the DSS, the experts agreed that the CHWs can easily incorporate it into their routines and the app can identify patients at risk and improve treatment. CONCLUSIONS: The COVID-19 pandemic caused a significant drop in the number of consultations for patients with hypertension and DM in primary care. A DSS for CHW has proved to be feasible, useful, and easily incorporated into their routines.

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.

Development and Implementation of a Methodology for Quality Assessment of Asynchronous Teleconsultations.

Background: There is a lack of evidence regarding audits or quality analysis of telehealth strategies in clinical practice. Our aim is to develop and implement a methodology for quality assessment of asynchronous teleconsultations. Materials and Methods: A random sample of asynchronous teleconsultations performed by the specialists from the Telehealth Network of Minas Gerais (TNMG), a public telehealth service in Brazil, was selected. The responses were evaluated regarding size, objectivity, quality, ethics, courtesy, and grammar, and received a score for each category: 1 = fair, 2 = moderate, and 3 = good. As each domain has a different importance in rating the overall quality of teleconsultation, each one was assigned a different weight, and a final score was calculated. Results: A total of 576 teleconsultations were assessed. Overall, the scores were good or moderate for all items. Only a few cases were classified as fair. Among medical specialties, pediatrics was the one that proportionally received the highest number of fair classifications, and the item "quality of the answers" was the one with highest number of worse classifications for this specialty. Corrective actions were implemented. With regard to the nonmedical specialties, the majority of the items were classified as good or moderate, and in rare cases some items received the fair rating. Conclusion: The methodology showed to be useful to evaluate the teleconsultation service. We established six domains that we considered important components to be assessed. This assessment was essential to identify the priority areas to receive correct actions. It may be easily replicated in other services worldwide.

The Impact of a Clinical Decision Support System in Diabetes Primary Care Patients in a Developing Country.

BACKGROUND: Telehealth strategies have the potential to improve diabetes care, but there is a lack of evidence about the impact of these strategies in developing countries. Our objective was to analyze the feasibility, usability, and clinical impact of a decision support system (DSS) in Brazilian primary care diabetes patients. MATERIALS AND METHODS: This was a quasi-experimental study that included type 2 diabetes primary care patients >40 years of age. Patients were assessed before (during 6 months) and after the implementation of the DSS application (4 months). The DSS application, used by health professionals, included clinical evaluations and blood glucose measurements and generated specific recommendations based on the data entered. RESULTS: In total, 145 patients were included (mean age, 62.0 ± 9.9 years), 62.1% were female, and 70.0% had been diagnosed with diabetes more than 5 years ago. Overall, there was no decrease in median hemoglobin A1c (HbA1c), from 7.7% (range, 6.5-9.8%) to 7.4% (range, 6.5-9.2%) (P for slope = 0.347). Subgroup analysis showed that patients with an HbA1c level of ≥9% at baseline had a significant reduction in median HbA1c level, from 10.5% (range, 9.9-11.3%) to 10.0% (range, 8.9-10.9%) (P for difference of slope between subgroups = 0.004). The reduction occurred in the first phase of the study, before the DSS use. Healthcare practitioners considered the DSS easy to use (99%) and believed that it provided useful information for patient care (100%). CONCLUSIONS: In this study the improvement of glycemic control before the application in more decompensated patients (HbA1c ≥9%) probably reflects the systematization of diabetes care. The DSS use did not improve the HbA1c level, possibly because of the short follow-up and/or infrequent use by the healthcare practitioners.

Clinical Quality Control of a Large-Scale Teleconsultation Service.

The Telehealth Network of Minas Gerais (TNMG) is a public telehealth service in Brazil that assists 722 municipalities in the state of Minas Gerais. As a large-scale teleconsultation service, it was important to implement clinical quality control to guarantee the quality of the service. Our aim is to describe the audit of the teleconsultation responses performed by TNMG. A random sample was selected from teleconsultations performed by the specialists from the TNMG between January and February 2014. The responses were evaluated regarding size, objectivity, quality, ethics, courtesy and grammar. A total of 640 teleconsultation responses were assessed, and the mean scores were ≥2.45. Objectivity and quality had the lowest scores in the different specialities. The methodology was useful for evaluating the teleconsultation service and for identifying the areas to improve.

Telemedicine application in the care of diabetes patients: systematic review and meta-analysis.

BACKGROUND: The impact of telemedicine application on the management of diabetes patients is unclear, as the results are not consistent among different studies. The objective of this study is to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) assessing the impact of telemedicine interventions on change in hemoglobin A1c (HbA1c), blood pressure, LDL cholesterol (LDL-c) and body mass index (BMI) in diabetes patients. METHODS: Electronic databases MEDLINE, Cochrane Central Register of Controlled Trials and LILACS were searched to identify relevant studies published until April 2012, supplemented by references from the selected articles. Study search and selection were performed by independent reviewers. Of the 6.258 articles retrieved, 13 RCTs (4207 patients) were included. Random effects model was applied to estimate the pooled results. RESULTS: Telemedicine was associated with a statistically significant and clinically relevant absolute decline in HbA1c level compared to control (mean difference -0.44% [-4.8 mmol/mol] and 95% confidence interval [CI] -0.61 to -0.26% [-6.7 to -2.8 mmol/mol]; p<0.001). LDL-c was reduced in 6.6 mg/dL (95% CI -8.3 to -4.9; p<0.001), but the clinical relevance of this effect can be questioned. No effects of telemedicine strategies were seen on systolic (-1.6 mmHg and 95% CI -7.2 to 4.1) and diastolic blood pressure (-1.1 mmHg and 95% CI -3.0 to 0.8). The 2 studies that assessed the effect on BMI demonstrated a tendency of BMI reduction in favor of telemedicine. CONCLUSIONS: Telemedicine strategies combined to the usual care were associated with improved glycemic control in diabetic patients. No clinical relevant impact was observed on LDL-c and blood pressure, and there was a tendency of BMI reduction in diabetes patients who used telemedicine, but these outcomes should be further explored in future trials.

Segunda opinião formativa: como fazer o diagnóstico de pré-diabetes? E como abordar essa condição?

O pré-diabetes corresponde a níveis de glicemia acima do normal, porém abaixo dos níveis definidores de diabetes. Indivíduos com essa condição apresentam risco aumentado de evolução para diabetes futuramente. Indivíduos com pré-diabetes frequentemente apresentam outras comorbidades, como obesidade, hipertensão, dislipidemia e, consequentemente, risco aumentado para eventos cardiovasculares. Portanto, uma vigilância aumentada se justifica para identificar e tratar esses e outros fatores de risco.

Segunda opinião formativa: como avaliar os pés dos pacientes diabéticos? É indispensável usar monofilamento para testar sensibilidade?

Todos os indivíduos diabéticos devem receber avaliações dos pés, começando ao diagnóstico no diabetes tipo 2 e cinco anos após diagnóstico no diabetes tipo 1. Manter reavaliações pelo menos anuais com testes clínicos simples. É importante buscar e registrar apropriadamente os fatores de risco para ulcerações e amputações.

Segunda opinião formativa: o que é hiperprolactinemia? Como deve ser sua abordagem na Atenção Primária à Saúde (APS)?

Hiperprolactinemia é a alteração endócrina mais comum do eixo hipotálamo-hipofisário e pode ser a etiologia em 20% a 25% das pacientes com amenorreia secundária. As causas de hiperprolactinemia são diversas, e podem ser classificadas em fisiológicas, farmacológicas e patológicas. Entre as causas patológicas, a mais importante são os prolactinomas, adenomas da hipófise que secretam prolactina.
