OBJECTIVES

Primary mental health admissions are increasing across US children’s hospitals. These patients may experience agitation requiring pharmacologic restraint. This study characterized pharmacologic restraint use in medical inpatient units by primary mental health diagnosis.

METHODS

This retrospective, cross-sectional study used the Pediatric Health Information System database. The study included children aged 5 to 17 years admitted with a primary mental health diagnosis between 2016 and 2021. Rates of pharmacologic restraint use per 1000 patient days were determined for 13 mental health diagnoses and trended over time with Poisson regression.

RESULTS

Of 91 898 hospitalizations across 43 hospitals, 3% of admissions and 1.3% of patient days involved pharmacologic restraint. Trends in the rate of pharmacologic restraint use remained stable (95% confidence interval [CI], 0.7–2.1), whereas the incidence increased by 141%. Diagnoses with the highest rates of pharmacologic restraint days per 1000 patient days included autism (79.4; 95% CI, 56.2–112.3), substance-related disorders (45.0; 95% CI, 35.9–56.4), and disruptive disorders (44.8; 95% CI, 25.1–79.8). The restraint rate significantly increased in disruptive disorders (rate ratio [RR], 1.4; 95% CI, 1.1–1.6), bipolar disorders (RR, 2.0; 95% CI, 1.4–3.0), eating disorders (RR, 2.4; 95% CI, 1.5–3.9), and somatic disorders (RR, 4.2; 95% CI, 1.9–9.1). The rate significantly decreased for autism (RR, 0.8; 95% CI, 0.6–1.0) and anxiety disorders (RR, 0.3; 95% CI, 0.2–0.6).

CONCLUSIONS

Pharmacologic restraint use among children hospitalized with a primary mental health diagnosis increased in incidence and varied by diagnosis. Characterizing restraint rates and trends by diagnosis may help identify at-risk patients and guide targeted interventions to improve pharmacologic restraint utilization.
