چکیده انگلیسی

ObjectiveTo evaluate the performance of the Pediatric Index of Mortality 2 (PIM2) in a pediatric intensive care unit (PICU) with a high prevalence of patients with complex chronic conditions (CCCs), and compare the performance between patients with and without CCCs.MethodsA prospective cohort study was conducted in a PICU in Brazil, with patients admitted between 2009 and 2011. The performance was evaluated through discrimination and calibration. Discrimination was assessed by calculating the area under the ROC curve, and calibration was determined using the Hosmer-Lemeshow goodness-of-fit test.ResultsA total of 677 patients were included in the study, of which 83.9% had a CCC. Overall mortality was 9.7%, with a trend of higher mortality among patients with CCCs when compared to patients without CCCs (10.3% vs. 6.4%, p = 0.27), but with no difference in the mean probability of death estimated by PIM2 (5.9% vs. 5.6%, p = 0.5). Discrimination was considered adequate in the general population (0.840) and in patients with and without CCCs (0.826 and 0.944). Calibration was considered inadequate in the general population and in patients with CCCs (p < 0.0001 and p < 0.0001), but it was considered adequate in patients without CCCs (p = 0.527).ConclusionsPIM2 showed poor performance in patients with CCCs and in the general population. This result may be secondary to differences in the characteristics between the study samples (high prevalence of patients with CCCs); the performance of the PIM2 should not be ruled out.

ResumoObjetivoAvaliar o desempenho do Pediatric Index of Mortality 2 (PIM2) em Unidade de Terapia Intensiva Pediátrica (UTIP) com alta prevalência de pacientes com condições crônicas complexas (CCC), e comparar o desempenho entre pacientes com e sem CCC.MétodosEstudo de coorte prospectivo, realizado em UTIP no Brasil, com pacientes admitidos entre 2009 e 2011. O desempenho foi avaliado através da discriminação e calibração. A discriminação foi avaliada através do cálculo da área sob a curva ROC e a calibração através do teste de ajuste de Hosmer-Lemeshow.ResultadosForam incluídos no estudo 677 pacientes, com 83,9% deles apresentando uma CCC. A mortalidade geral foi 9,7%, com tendência de maior mortalidade entre pacientes com CCC quando comparados com pacientes sem CCC (10,3% vs. 6,4%; p = 0,27), porém sem diferença na média de probabilidade de morte estimada pelo PIM2 (5,9% vs. 5,6%; p = 0,5). A discriminação foi considerada adequada na população geral (0,840) e nos pacientes com e sem CCC (0,826 e 0,944). A calibração foi considerada inadequada na população geral e nos pacientes com CCC (p < 0,0001 e p < 0,0001), porém foi considerada adequada nos pacientes sem CCC (p = 0,527).ConclusõesO PIM2 apresentou desempenho inadequado nos pacientes com CCC e na população geral. O desempenho inadequado pode ser secundário à diferença das características entre as amostras do estudo (alta prevalência de pacientes com CCC), e o desenvolvimento do escore não pode ser descartado.
