Acute inpatient 28-day readmission

Acute inpatient 28-day readmission measures the percentage of acute inpatient discharges that are readmitted to another acute inpatient stay within the 28 days following discharge. Psychiatric inpatient services aim to provide treatment that enables individuals to return to the community as soon as possible. Unplanned admissions to a psychiatric facility following a recent discharge may indicate that inpatient treatment was either incomplete or ineffective, or that follow-up care was inadequate to maintain the person out of hospital.

Data available through May 2021, sourced from a June 20, 2021 refresh of the PRIMHD DataMart.

Note that activity data is only available through February 2021 for Hawkes Bay, and through April 2021 for Waikato and Nelson Marlborough. Please exercise caution when viewing recent time periods in any reports.
