Impact of integrating psychiatric assessment officers via telepsychiatry on rural hospitals' emergency revisit rates.

Objective: To assess the impact of integrating Psychiatric Assessment Officers (PAO) and telepsychiatry in rural hospitals on their all-cause emergency department (ED) revisit rates. As a pilot project, a full-time PAO was embedded in each of three rural hospitals in New York State and was augmented by telepsychiatry.

Method: A retrospective data analysis using ED census data obtained from the hospitals. The intervention group, defined as those patients treated by PAOs, was compared via a difference-in-difference method against a contemporaneous comparison group defined as those who visited the same EDs and had PAO-qualifying behavioral health diagnoses but were not seen by PAOs.

Results: The intervention group was associated with an approximately 36% lower all-cause ED revisit rate during the first 90-day period (i.e. 1-90 days) following the initial PAO treatment (p = .003). A reduction of the similar magnitude (44%) persisted into the subsequent 90-day period (i.e., 91-180 days since the initial PAO treatment; p < .001).

Conclusion: The PAO telepsychiatry pilot program suggests a potential way to provide relief for overburdened EDs in rural communities that lack resources to treat patients with severe behavioral health symptoms.
