Background: Proactive psychiatric consultation services rapidly identify and assess medical inpatients in need of psychiatric care. In addition to more rapid contact, proactive services may reduce the length of stay and improve staff satisfaction. However, in some settings, it is impractical to integrate a proactive consultation service into every hospital unit; on-request and proactive services are likely to coexist in the future. Prior research has focused on changes in outcomes with the implementation of proactive services.
Objective and methods: This report describes differences between contemporary proactive and on-request services within the same academic medical center, comparing demographic and clinical data collected retrospectively from a 4-year period from the electronic medical record.
Results: The proactive service saw patients over four times as many initial admissions (7592 vs. 1762), but transitions and handoffs between services were common, with 434 admissions involving both services, comprising nearly 20% of the on-request service's total contacts. The proactive service admissions had a shorter length of stay and a faster time to first psychiatric contact, and the patients seen were more likely to be female, of Black race, and to be publicly insured. There were over three times as many admissions to psychiatry from the proactive service. The on-request service's admissions had a longer length of stay, were much more likely to involve intensive care unit services, surgical services, and transfers among units, and the patients seen were more likely to die in the hospital or to be discharged to subacute rehabilitation.
Conclusions: Overall, the results suggest that the two services fulfill complementary roles, with the proactive service's rapid screening and contact providing care to a high volume of patients who might otherwise be unidentified and underserved. Simultaneously, the on-request service's ability to manage patients in response to consult requests over a much larger area of the hospital provided important support and continuity for patients with complex health needs. Institutions revising their consultation services will likely need to consider the best balance of these differing functions to address perceived demand for services.
