          Abstract

          RESUMO: Objetivo: Medir os atrasos na suspeita e no diagnóstico de tuberculose (TB) e identificar fatores relacionados. Métodos: O atraso na suspeita foi definido como o tempo entre a percepção, pelo doente, dos sintomas até a procura pelo primeiro atendimento e no diagnóstico, como o tempo entre o primeiro atendimento até a realização do diagnóstico. Foram entrevistados 100 doentes, diagnosticados e notificados em 2008 e 2009, atendidos em serviços de saúde (SSs) de São José do Rio Preto, para os quais foram quantificados os atrasos. As possíveis variáveis explicativas foram obtidas das entrevistas e de informações secundárias disponíveis no sistema de vigilância. Os endereços dos casos e dos serviços de saúde foram geocodificados. As variáveis foram analisadas por regressão linear múltipla e, quando da identificação de dependência espacial dos seus resíduos, por regressão espacial. Resultados: As medianas, tanto para o atraso na suspeita como no diagnóstico, foram 15 dias. O atraso na suspeita foi modelado por regressão linear e mostrou-se associado positivamente com as distâncias percorridas pelos doentes para obter o primeiro atendimento e negativamente com a religião (não cristã). O atraso no diagnóstico foi modelado por regressão espacial e mostrou-se associado positivamente com idade e número de vezes que o doente procurou o SS e negativamente com a classificação do caso (TB pulmonar). Conclusão: O estudo revelou lacunas nas ações de controle da TB relacionadas aos doentes e à organização dos serviços e mostrou a importância de se levar em conta a dependência espacial dos fenômenos analisados.

          ABSTRACT: Objective: To measure the delays in tuberculosis (TB) suspicion and diagnosis and to identify factors related. Methods: We defined the delay in TB suspicion as the time between the perception of the symptoms by the patient and the search for health-care service and the diagnosis, as the time between the first visit to the health-care service and the diagnosis. We interviewed 100 patients treated at the health services in São José do Rio Preto that were diagnosed and reported/notified in 2008 and 2009, and the delays were quantified. We obtained the possible explanatory variables from interviews and secondary information available in the surveillance system. The addresses of TB patients and health-care services were geocoded. Variables were assessed by multiple linear regression analysis and, when spatial dependency was detected, by spatial regression. Results: The median values for the delays in TB suspicion and diagnosis were both 15 days. The first was modeled by linear regression and a positive relationship was found with the distances covered by the patients in order to get primary health-care service. The last was modeled by spatial regression and a positive relationship was found with the age and the frequency with the patients sought health-care services and a negative relationship with the pulmonary clinical form. Conclusion: The study revealed the existence of gaps in TB control activities related to the patients and the organization of the health-care services and showed the importance of taking into account the spatial dependence of the phenomena analyzed.

              Diagnostic and treatment delay among pulmonary tuberculosis patients in Ethiopia: a cross sectional study

              Background Delayed diagnosis and treatment of tuberculosis (TB) results in severe disease and a higher mortality. It also leads to an increased period of infectivity in the community. The objective of this study was to determine the length of delays, and analyze the factors affecting the delay from onset of symptoms of pulmonary tuberculosis (PTB) until the commencement of treatment. Methods In randomly selected TB management units (TBMUs), i.e. government health institutions which have diagnosing and treatment facilities for TB in Amhara Region, we conducted a cross sectional study from September 1-December 31/2003. Delay was analyzed from two perspectives, 1. Period between onset of TB symptoms to first visit to any health provider (health seeking period), and from the first health provider visit to initiation of treatment (health providers' delay), and 2. Period between onset of TB symptoms to first visit to a medical provider (patients' delay), and from this visit to commencement of anti-TB treatment (health systems' delay). Patients were interviewed on the same date of diagnosis using a semi-structured questionnaire. Logistics regression analysis was applied to analyze the risk factors of delays. Results A total of 384 new smear positive PTB patients participated in the study. The median total delay was 80 days. The median health-seeking period and health providers' delays were 15 and 61 days, respectively. Conversely, the median patients' and health systems' delays were 30 and 21 days, respectively. Taking medical providers as a reference point, we found that forty eight percent of the subjects delayed for more than one month. Patients' delays were strongly associated with first visit to non-formal health providers and self treatment (P < 0.0001). Prior attendance to a health post/clinic was associated with increased health systems' delay (p < 0.0001). Conclusion Delay in the diagnosis and treatment of PTB is unacceptably high in Amhara region. Health providers' and health systems' delays represent the major portion of the total delay. Accessing a simple and rapid diagnostic test for TB at the lowest level of health care facility and encouraging a dialogue among all health providers are imperative interventions.
