regressão.Códigos JEL: C24; C61; I11; R15.O presente trabalho realiza uma avaliação dos serviços ambulatoriais e hospitalares nos municípios do estado do Rio de Janeiro. A avaliaçãoé realizada com base em fronteiras de eficiência não-estocásticas, combinadas com modelos de regressão, contemplando variáveis relacionadas com os recursos e a produção de serviços nos municípios. O desempenho dos serviços de saúde dos municípios e das regiões do estado e os níveisótimos de produção e de consumo estão explicitados. São obtidas relações entre eficiência técnica, produto interno bruto, tamanho da população e o prazo médio de internação nos municípios.The present paper assesses health care services delivered in ambulatories and hospitals in the municipalities of the state of Rio de Janeiro, Brazil. The assessment is based on the use of non-stochastic frontiers models (data envelopment analysis -DEA) combined with regression techniques. By taking advantage of resources and production data, optimal levels of consumption and services are obtained. The paper shows relationships related to technical efficiency, GDP, population size and average length-of-stay.
This study analyzes the waiting lines for solid organ transplants in Brazil's Unified National Health System. By using a queuing theory model, we estimate the waiting times for different organs under alternative scenarios. The model reveals the elasticity of various waiting times with respect to arrival and service rates for organ transplantation within the system. Average waiting time for a solid organ transplant is very long and highly elastic in Brazil. The article discusses some important possibilities for reducing such waiting times.
Objective: Diabetes mellitus is the main cause of Charcot neuroarthropathy and is clinically classified as follows: Charcot foot, acute Charcot foot (ACF) when there is inflammation, and inactive Charcot foot when inflammatory signs are absent. The aim of this study was to identify the risk factors for ACF in patients with type 2 diabetes mellitus. Materials and methods: A matched case-control study was conducted to assess the factors associated with acute Charcot foot from February 2000 until September 2012. Four controls for each case were selected 47 cases of ACF and 188 controls without ACF were included. Cases and controls were matched by year of initialization of treatment. Conditional logistic regression was used to estimate matched odds ratios (ORs) and 95% confidence intervals (95% CIs). Results: In multivariate analysis, patients having less than 55 years of age (adjusted OR = 4.10, 95% CI = 1.69 -9.94), literate education age (adjusted OR = 3.73, 95% CI = 1.40 -9.92), living alone (adjusted OR = 5.84, 95% CI = 1.49 -22.86), previous ulceration (adjusted OR = 4.84, 95% CI = 1.62 -14.51) were at increased risk of ACF. However, peripheral arterial disease (adjusted OR = 0.16, 95% CI = 0.05 -0.52) of 6.25 (1.92 -20.0) was a protective factor. Discussion: The results suggest that PCA in type 2 diabetes primarily affects patients under 55 who live alone, are literate, and have a prior history of ulcers, and that peripheral arterial disease is a protective factor.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
