Importance of GP contact on readmission rate following psychiatric acute care: A Danish Nationwide study.

ABSTRACT

Insufficient acute psychiatric care substantially impacts patient well-being and healthcare quality. Early readmissions after discharge from psychiatric care are common, and preventing these is important for the patients as well as appropriate resource allocation. The relationship between post-discharge general practitioner (GP) contact and readmission rates remains to be explored, as does the association between pre-hospital GP contact and post-discharge engagement. AIM: This study examines post-discharge GP contact and its association with outpatient revisits and inpatient readmissions among unplanned psychiatric hospital contacts, including the impact of pre-visit GP contact on post-discharge care within 14 days. METHODS: Utilizing data from the Danish healthcare system (2019-2023), unplanned psychiatric hospital contacts and subsequent 14-day GP encounters were analyzed. RESULTS: Of 298,085 unplanned psychiatric hospital contacts, 12.6% had a 14-day revisit as an outpatient and 13.6% had a 14-day readmission as an inpatient. During regular business hours, GP contact was associated with a decreased risk of unplanned outpatient revisits (HR 0.45, 95% CI 0.44-0.47) and inpatient readmissions (HR 0.43, 95% CI 0.41-0.44). Similarly, utilizing GP on-call services was linked to a reduced risk of unplanned revisits (HR 0.87, 95% CI 0.81-0.94) and readmissions (HR 0.81, 95% CI 0.76-0.87). Having a GP contact within two days before an unplanned psychiatric hospital contact increased the likelihood of having a GP contact within 14 days post-discharge. CONCLUSION: Post-discharge GP encounters were associated with lower rates of 14-day outpatient revisits and inpatient readmissions following unplanned psychiatric hospital contacts. GP contact before psychiatric hospital contact enhances attendance at post-discharge appointments, suggesting a potential efficacy of promoting GP appointments for mental health care.
