Factors Associated with Revision Surgery after Internal Fixation of Hip Fractures

Background: Femoral neck fractures are associated with high rates of revision surgery after management with internal fixation. Using data from the Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trial evaluating methods of internal fixation in patients with femoral neck fractures, we investigated associations between baseline and surgical factors and the need for revision surgery to promote healing, relieve pain, treat infection or improve function over 24 months postsurgery. Additionally, we investigated factors associated with (1) hardware removal and (2) implant exchange from cancellous screws (CS) or sliding hip screw (SHS) to total hip arthroplasty, hemiarthroplasty, or another internal fixation device. Methods: We identified 15 potential factors a priori that may be associated with revision surgery, 7 with hardware removal, and 14 with implant exchange. We used multivariable Cox proportional hazards analyses in our investigation. Results: Factors associated with increased risk of revision surgery included: female sex, [hazard ratio (HR) 1.79, 95% confidence interval (CI) 1.25-2.50; P = 0.001], higher body mass index (fo

Acesso a ambulatório pediátrico de um hospital universitário Evaluation of access to the pediatric service of a university hospital

INTRODUÇÃO: No Brasil verifica-se um descompasso entre o aumento das necessidades de atenção à saúde e de sua oferta. O Sistema Único de Saúde, cujas deretrizes preconizam a atenção universal e eqüânime, determina a relevância desta temática dentro do campo da avaliação dos serviços de saúde. Assim, foram estudados dois ambulatórios de pediatria de um hospital universitário, um geral e outro de uma subespecialiadade (pneumologia), comparando os usuários quanto ao acesso. MÉTODO: Foram aplicados 221 questionários entre clientes de ambos os ambulatórios de pediatria com o objetivo de se estudar e comparar variáveis socioeconômicas, procedência, acesso aos referidos ambulatórios e outros serviços de saúde. RESULTADOS: Evidenciou-se grande dificuldade de locomoção dos pacientes, a maioria dos quais são encaminhados por serviços de saúde locais. Dos pacientes atendidos 40% não receberam nenhum atendimento anteriormente à sua chegada ao hospital, fato que decorre principalmente de seu baixo nível socioeconômico, que os torna dependentes exclusivamente dos serviços públicos de saúde. A comparação entre os dois ambulatórios mostra que os pacientes do ambulatório de especialidade têm melhor nível socioeconômico e são menos dependentes dos serviços públicos, configurando desta forma uma situação de ineqüidade. CONCLUSÕES: É apontado o melhor nível socioeconômico dos usuários da especialidade bem como questões organizacionais do próprio serviço como os responsáveis pela iniqüidade verificada.<br>INTRODUCTION: In Brazil, one can verify an imbalance between the increase in the need for health care and its supply. The consolidation of the National Health System which recommends universality and equity in care, makes this issue important in the field of health service evaluation. Two pediatric services in a university hospital, one general and the other specialized are studied and compared in terms of their clients' access. METHOD: Questionnaires were applied to 221 users of the general pediatrics outpatient departments of one of the specialities with a view to studying and comparing socioeconomic and several other variables related to the access to these and other health services. RESULTS: A high level of difficulty in the users' locomotion from local health services to the hospital was noted.Of the patients attended, 40% did not receive any kind of care before their arrival and were dependent exclusively on State-run health services. The clients of the speciality were different as regards several variables when compared to the users of the general outpatients' department. The fact that they are at a better socioeconomic level and are less dependent on State-run services brings out the social inequalities involved. CONCLUSION: Socioeconomic conditions, as well as organizational aspects of the service, are seen to be both causes and consequences of social inequalitiy verified
