Psychiatric Comorbidities in Pediatric Inpatients With Human Immunodeficiency Virus Infection and Impact on Hospital Course: Inputs From a Case-Control Inpatient Study

Objectives In this study, we aimed to delineate psychiatric comorbidities in pediatric inpatients with versus without human immunodeficiency virus (HIV) infection and to measure its impact on the length of stay (LOS) and cost of treatment during hospitalization. Methodology We conducted a case-control study using the Nationwide Inpatient Sample and included 4,920 pediatric inpatients between the ages of six and 18 years who were sub-grouped by a comorbid diagnosis of HIV (N = 2,595) and non-HIV (N = 2,325) and matched for demographics (age, sex, and race) by propensity case-control matching. Logistic regression analyses were used to evaluate the adjusted odds ratio (aOR) of association for psychiatric comorbidities (depression, anxiety, post-traumatic stress disorder, psychosis, and drug abuse) in the HIV-positive compared with the HIV-negative (as reference category) pediatric inpatients. We measured the differences in the LOS and cost using the independent sample t-test. Results We found that the most prevalent psychiatric comorbidities in the HIV-positive group were anxiety (6.9%), drug abuse (6.6%), psychosis (6.4%), and depression (6.2%). The HIV-positive group had a significantly higher likelihood of comorbid psychosis (aOR: 1.82; 95% confidence interval [CI]: 1.38-2.40) and depression (aOR: 1.79; 95% CI: 1.36-2.36). The mean LOS per hospitalization episode was longer for the HIV-positive group (11.1 days vs. 6.0 days; P < 0.001) compared to the HIV-negative pediatric inpatients. Conclusions We found an increased risk of depression by 79% and psychosis by 82% in the HIV-positive pediatric population. These inpatients also had an extended hospitalization stay (by five days), adding to the healthcare economic burden.
