ObjectiveTo identify those patients in a pediatric intensive care unit who may be at highest risk for developing persistent psychological sequelae after hospital discharge.DesignA secondary data analysis was conducted to examine data gathered in an earlier study of children's psychological responses after critical illness. The current study focused exclusively on patients who required pediatric intensive care unit hospitalization.PatientsSixty children, aged 6 to 17 yrs, hospitalized in two Canadian pediatric intensive care units.ProceduresChildren were categorized as either high risk or low risk for developing persistent psychological sequelae after discharge based on their level of illness severity and the number of invasive procedures to which they were exposed. Outcome data were analyzed using descriptive statistics, followed by an assessment of group differences at baseline, 6 wks, and 6 mos postdischarge. Combined effects of invasive procedures and illness severity on the outcome variables were explored.Outcome MeasuresThree questionnaires were completed by all children 6 wks and 6 mos postdischarge, including the Children's Impact of Events Scale, the Children's Medical Fears Scale, and the Children's Health Locus of Control Scale.ResultsChildren in the high risk group demonstrated more psychological sequelae 6 wks and 6 mos postdischarge. Exposure to high numbers of invasive procedures was the most important predictor of group differences 6 wks postdischarge.ConclusionsFindings suggest there is a group of children in the pediatric intensive care unit who are at higher risk for developing persistent psychological sequelae postdischarge. Exposure to high numbers of invasive procedures may be the driving force behind group differences, particularly at 6 wks postdischarge. These children warrant closer observation and follow-up.
