Avaliação de desempenho do controle da tuberculose em municípios brasileiros

OBJETIVO Avaliar o desempenho no controle da tuberculose dos municípios brasileiros. MÉTODOS Estudo ecológico com municípios brasileiros que notificaram pelo menos quatro casos novos de tuberculose, com no mínimo um caso novo de tuberculose pulmonar entre 2015 e 2018. Os municípios foram estratificados de acordo com a população em < 50 mil, 50–100 mil, 100–300 mil e > 300 mil habitantes e foi utilizado o método k-médias para agrupá-los dentro de cada faixa populacional segundo desempenho de seis indicadores da doença. RESULTADOS Foram incluídos 2.845 municípios brasileiros abrangendo 98,5% (208.007/211.174) dos casos novos de tuberculose do período. Para cada faixa populacional identificou-se três grupos (A, B e C) de municípios segundo desempenho dos indicadores: A os mais satisfatórios, B os intermediários e C os menos satisfatórios. Municípios do grupo A com < 100 mil habitantes apresentaram resultados acima das metas para confirmação laboratorial (≥ 72%), abandono (≤ 5%) e cura (≥ 90%), e abrangeram 2% dos casos novos da doença. Por outro lado, os municípios dos grupos B e C apresentaram pelo menos cinco indicadores com resultados abaixo das metas – testagem HIV (< 100%), exame de contatos (< 90%), tratamento diretamente observado (< 90%), abandono (> 5%) e cura (< 90%) –, e corresponderam a 66,7% dos casos novos de tuberculose. Já no grupo C dos municípios com > 300 mil habitantes, que incluiu 19 das 27 capitais e 43,1% dos casos novos de tuberculose, encontrou-se os menores percentuais de exames de contatos (média = 56,4%) e tratamento diretamente observado (média = 15,4%), elevado abandono (média = 13,9%) e baixa cobertura da atenção básica (média = 66,0%). CONCLUSÕES Grande parte dos casos novos de tuberculose ocorreu em municípios com desempenho insatisfatório para o controle da doença, onde expandir a cobertura da atenção básica pode reduzir o abandono e elevar o exame de contatos e tratamento diretamente observado.OBJECTIVE To evaluate the performance of tuberculosis control in Brazilian municipalities. METHODS This is an ecological study on Brazilian municipalities that notified at least four new cases of tuberculosis, with a minimum of one new case of pulmonary tuberculosis between 2015 and 2018. The municipalities were stratified according to the population in < 50 thousand, 50–100 thousand, 100–300 thousand, and > 300 thousand inhabitants, and the k-means method was used to group them within each population range according to the performance of six indicators of the disease. RESULTS A total of 2,845 Brazilian municipalities were included, comprising 98.5% (208,007/211,174) of new tuberculosis cases in the period. For each population range, three groups (A, B, and C) of municipalities were identified according to the performance of the indicators: A, the most satisfactory; B, the intermediates; and C, the least satisfactory. Municipalities in group A with < 100 thousand inhabitants presented results above the targets for laboratory confirmation (≥ 72%), abandonment (≤ 5%), and cure (≥ 90%), and comprised 2% of new cases of the disease. Conversely, municipalities of groups B and C presented at least five indicators with results below the targets – HIV testing (< 100%), contact investigation (< 90%), directly observed therapy (< 90%), abandonment (> 5%), and cure (< 90%) –, and corresponded to 66.7% of new cases of tuberculosis. In group C of municipalities with > 300 thousand inhabitants, which included 19 of the 27 capitals and 43.1% of new cases of tuberculosis, the lowest percentages of contact investigation (mean = 56.4%) and directly observed therapy (mean = 15.4%) were verified, in addition to high abandonment (mean = 13.9%) and low coverage of primary health care (mean = 66.0%). CONCLUSIONS Most new cases of tuberculosis occurred in municipalities with unsatisfactory performance for disease control. Expanding the coverage of primary health care in these places can reduce abandonment and increase the contact investigation and directly observed therapy

Rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART): Study protocol for a randomized controlled trial

Background: Acute respiratory distress syndrome (ARDS) is associated with high in-hospital mortality. Alveolar recruitment followed by ventilation at optimal titrated PEEP may reduce ventilator-induced lung injury and improve oxygenation in patients with ARDS, but the effects on mortality and other clinical outcomes remain unknown. This article reports the rationale, study design, and analysis plan of the Alveolar Recruitment for ARDS Trial (ART). Methods/Design: ART is a pragmatic, multicenter, randomized (concealed), controlled trial, which aims to determine if maximum stepwise alveolar recruitment associated with PEEP titration is able to increase 28-day survival in patients with ARDS compared to conventional treatment (ARDSNet strategy). We will enroll adult patients with ARDS of less than 72 h duration. The intervention group will receive an alveolar recruitment maneuver, with stepwise increases of PEEP achieving 45 cmH(2)O and peak pressure of 60 cmH2O, followed by ventilation with optimal PEEP titrated according to the static compliance of the respiratory system. In the control group, mechanical ventilation will follow a conventional protocol (ARDSNet). In both groups, we will use controlled volume mode with low tidal volumes (4 to 6 mL/kg of predicted body weight) and targeting plateau pressure <= 30 cmH2O. The primary outcome is 28-day survival, and the secondary outcomes are: length of ICU stay; length of hospital stay; pneumothorax requiring chest tube during first 7 days; barotrauma during first 7 days; mechanical ventilation-free days from days 1 to 28; ICU, in-hospital, and 6-month survival. ART is an event-guided trial planned to last until 520 events (deaths within 28 days) are observed. These events allow detection of a hazard ratio of 0.75, with 90% power and two-tailed type I error of 5%. All analysis will follow the intention-to-treat principle. Discussion: If the ART strategy with maximum recruitment and PEEP titration improves 28-day survival, this will represent a notable advance to the care of ARDS patients. Conversely, if the ART strategy is similar or inferior to the current evidence-based strategy (ARDSNet), this should also change current practice as many institutions routinely employ recruitment maneuvers and set PEEP levels according to some titration method.Hospital do Coracao (HCor) as part of the Program 'Hospitais de Excelencia a Servico do SUS (PROADI-SUS)'Brazilian Ministry of Healt

Salvador, BA, BrasilUniversidade Federal da Bahia. Instituto de Saúde Coletiva. Salvador, BA, BrasilDifferent instruments have been used to measure social support in epidemiological studies of which the most widely used is the Medical Outcomes Study Social Support Scale (SSS-MOS). However, these studies lack measures of the level of social support on health risks. We used latent class analysis (LCA) to distinguish subgroups with different levels of perceived social support and tested the consistency of these subgroups by their associations with the prevalence of Common Mental Disorders (CMD). This is a cross-sectional study of 1013 mothers living in the city of Salvador, Brazil in which psychosocial data were collected through home visits using the SSS-MOS and the Self Reporting Questionnaire-20. For each dimension of social support analysed here, we selected models with two classes using LCA. Multivariate logistic regression models were used to estimate the association between participants' perceived social support and the prevalence of CMD to verify the consistency of the groups defined by LCA. There was a clear difference in the reporting of perceived social support between those classified as high or low using LCA. The probability of perceiving several types of social support was lower in the subgroup classified as low level of social support (13.7-59.8%), and it was much higher in the group classified as high level of social support (84.3-98%). A greater prevalence of CMD was found among mothers with lower levels of social support. LCA seems to be a useful tool to improve measurement of perceived social support by separation into two levels in which the lower level is associated with an increased prevalence of CMD

Acesso aos serviços de atenção primária à saúde por adolescentes e jovens em um município do Estado da Bahia, Brasil

Resumo: O estudo teve como objetivo analisar a associação entre o acesso aos serviços de atenção primária à saúde dos adolescentes e adultos jovens e a cobertura da Estratégia Saúde da Família (ESF). Trata-se de estudo transversal, a partir de um inquérito domiciliar realizado com 812 indivíduos de 15 a 24 anos de idade, em Camaçari, Bahia, Brasil, por meio de uma amostragem por conglomerados. Variáveis demográficas, socioeconômicas, de saúde e dos serviços de saúde foram utilizadas para descrição da população, segundo a área de cobertura de atenção primária à saúde. A associação entre área de cobertura da atenção primária à saúde e acesso aos serviços desta, as barreiras de acesso e a participação em atividades educativas foram estimadas por meio da razão de prevalência (RP), com uso do modelo de regressão logística multinível no software R. O acesso aos serviços de atenção primária à saúde foi referido por 89,5% dos indivíduos, não havendo diferenças estatisticamente significantes entre esse tipo de acesso e a área de cobertura da ESF. Entretanto, entre indivíduos residentes em áreas cobertas pela ESF, verificou-se maior acesso às ações de prevenção de agravos e promoção da saúde (RP = 3,0; IC95%: 1,68-5,34), mas também menor probabilidade de o atendimento ocorrer no mesmo dia de marcação da consulta (RP = 0,60; IC95%: 0,48-0,74) e menor disponibilidade de transporte coletivo (RP = 0,59; IC95%: 0,39-0,90). Os dados deste estudo apontaram elevada prevalência de acesso aos serviços de atenção primátria à saúde entre os adolescentes e adultos jovens. Ainda que não se tenham observado diferenças do acesso entre as áreas com cobertura da ESF, a maior participação desses indivíduos em atividades de prevenção e promoção da saúde reforçam a importância dessa estratégia no âmbito do Sistema Único de Saúde (SUS)
