Emergency Severity Index: accuracy in risk classification / Índice de Gravidade de Emergência: acurácia na classificação de risco

ABSTRACT Objective: To verify agreement between estimative of predicted resources using the adapted Emergency Severity Index and the real amount of resources used by patients. To analyze the variables number of years since graduation, years of work experience and years of experience in emergency services especially with accurate anticipation of resources need. Methods: This retrospective analytical study with a quantitative approach included 538 medical records of patients assisted by 11 triage nurses. Data collected were related to assistances carried out from December 2012 to February 2013. Results: There was no significant association between the adequacy of the number of resources used, based on Emergency Severity Index score, number of years since graduation, year of work experience or years of experience in emergency services. Kappa agreement coefficient (0.34) showed that agreement was low between predicted and real used number of resources. Conclusion: Nurses' accuracy index to predict resources for patients care from emergency room using the adapted Emergency Severity Index was lower than results reported in the studies in the literature that used the original scale. There was low agreement of diagnostic exams predicted by nurses and those really performed. There was no association among correct prediction of resources needed, number of years since graduation, years of experience in emergency services and years of work experience in the unit where the study was done.

RESUMO Objetivo: Verificar a concordância entre a estimativa de recursos previstos por meio do Índice de Gravidade de Emergência adaptada e aqueles utilizados pelos pacientes; e analisar as variáveis tempo de formado, experiência profissional e tempo de trabalho nos serviços de emergência com a assertividade da previsao de recursos. Métodos: Estudo retrospectivo analítico com abordagem quantitativa. A amostra foi de 538 prontuários de pacientes atendidos por 11 enfermeiros responsáveis pela classificação de risco. A coleta de dados foi realizada em relaçao ao período de atendimento de dezembro de 2012 a fevereiro de 2013. Resultados: Não houve associação significativa da adequação do número de recursos utilizados, de acordo com a classificação do Índice de Gravidade de Emergência, com o tempo de formação, de experiência ou de trabalho nos serviços de emergência. O coeficiente de concordância Kappa (0,34) demonstrou que a concordância entre o número previsto e o utilizado foi baixa. Conclusão: Os índices de assertividade dos enfermeiros na previsão de recursos, no atendimento de pacientes na unidade de pronto atendimento, utilizando o Índice de Gravidade de Emergência adaptado, foram inferiores aos descritos na literatura com a escala original. Houve baixa concordância dos exames diagnósticos previstos pelos enfermeiros com os realizados. Não foi observada associação na previsão correta do número de recursos com o tempo de formação, tempo de experiência nos serviços de emergência e tempo de trabalho na unidade de estudo.

Analysis of epidemiology, lifestyle, and psychosocial factors in patients with back pain admitted to an orthopedic emergency unit.

OBJECTIVE: To correlate epidemiological data, lifestyle, and psychosocial factors as predictors for clinical manifestation of back pain in patients treated at the orthopedic emergency unit of a Brazilian tertiary care hospital, and to evaluate their interest in participating in a hypothetical program for physical rehabilitation. METHODS: This is an observational cross-sectional study. We evaluated 210 patients from the emergency department of a tertiary hospital with a major complaint of back pain. We used: epidemiological multiple-choice questionnaires developed for this study; Oswestry questionnaire for physical disability; Hospital Anxiety and Depression Scale (HAD) scale. Data analyses were performed using SAS - Statistical Analysis System (SAS Institute, 2001). Measurements were performed with the SAS functions Proc MEANS and Proc Freq. RESULTS: The mean age was 39.1 years and there was no predominance between genders. The usual work activity was administrative (65.2% of cases). The mean body mass index was 26.0, indicating overweight. The majority (83.3%) of patients had low physical disability (Oswestry 0 - 40%). The number of medical visits in the previous 6 months (p=0.04) and the scores of anxiety and depression (p=0.05), independently, were correlated with physical disability. Most patients (77%) would agree to participate in a hypothetical program of physical rehabilitation for prevention of back pain. CONCLUSION: Patients with back pain complaints were predominantly young adults, sedentary or hypoactive, overweight, and with recurrent complaints of symptoms. Most participants had low levels of physical disability and would accept participation in a hypothetical physical rehabilitation program for the prevention of back pain.

RESUMO Objetivo: Correlacionar dados epidemiológicos, hábitos de vida e fatores psicossociais como preditivos para manifestação clínica de dorsolombalgia em pacientes atendidos no setor de urgências ortopédicas de hospital terciário brasileiro, além de avaliar o interesse em participar de programa hipotético para reabilitação física. Métodos: Trata-se de estudo observacional do tipo transversal. Foram avaliados 210 pacientes provenientes do pronto atendimento de um hospital terciário, com queixa predominante de dor nas costas. Foram utilizados: questionários epidemiológicos do tipo múltipla escolha desenvolvidos para o presente estudo; questionário Oswestry para incapacidade física; e escala Hospital Anxiety and Depression Scale (HAD). As análises dos dados foram realizadas por meio do programa SAS - Statistical Analysis System (SAS Institute, 2001). Os cálculos foram realizados com as funções Proc MEANS e Proc Freq do SAS. Resultados: A média de idade foi de 39,1 anos e não houve predominância entre os gêneros. A atividade laborativa mais frequente foi a administrativa (65,2% dos casos). Observou-se índice de massa corporal médio de 26,0, que indicou sobrepeso. A maioria (83,3%) dos pacientes apresentou baixa incapacidade física (Oswestry de 0 – 40%). O número de visitas nos 6 meses anteriores (p=0,04) e os escores de ansiedade e depressão (p=0,05), isoladamente, tiveram correlação com a incapacidade física. A maioria dos pacientes (77%) aceitaria participar de programa hipotético de reabilitação física para prevenção de dores nas costas. Conclusão: Os pacientes com queixa de dorsolombalgia foram, predominantemente, adultos jovens, sedentários ou hipoativos, com sobrepeso e com queixas recorrentes dos sintomas. A maioria dos participantes apresentou baixa incapacidade física e aceitaria participar de programa hipotético de reabilitação física para a prevenção de dores nas costas. .
