Odds ratios for clinical outcomes based on the antipsychotic treatment groups

	LOS ≥11 days aOR (95% CI)	Post-discharge institutionalization aOR (95% CI)	In-hospital mortality aOR (95% CI)
Antipsychotic treatment groupa	2.47 (1.51–4.07)b	4.47 (2.27–8.79)c	1.57 (0.76–3.25)

aOR adjusted odds ratio, CI confidence interval, LOS length of hospital stay

Bolded values indicate statistical significance

^aThe antipsychotic treatment groups are defined as 0 = no antipsychotics, 1 = antipsychotics only, and 2 = antipsychotics + lorazepam. Models are adjusted for age, sex and Charlson Comorbidity Index

^bPatients who died during the hospital stay were excluded

^cPatients who resided in an institutional care facility before admission, as well as patients who died during the hospital stay, were excluded
