Abstract
Background: An interest in hospital accreditation is growing rapidly among many countries to enhance the quality of health care services. The literature showed a positive association between accreditation and some processes of health care. One of the main factors that influence bed availability is the length of hospital stay (LOS), which is considered as an important indicator of the quality of inpatient psychiatric hospitalization. We aimed to investigate whether hospital accreditation drives improvements for the length of stay in psychiatric inpatients.
Methods: The study reviewed medical records of consecutive hospital admissions for pre- and post-accreditation comparisons of LOS in two acute mental health wards at a teaching general hospital in Riyadh, Saudi Arabia. Data obtained from the 12-month-post-accreditation period (July 2011 to June 2012) were compared with those from the 12-month-pre-accreditation period (July 2009 to June 2010). The adoption of accreditation program occurred over a 12-month period in the middle of the study (July 2010 to June 2011). Compiled information included demographics, diagnosis, assessment, and LOS. All identified charts were reviewed; there were no exclusion criteria. Patients were not contacted.
Results: Post-accreditation, the mean (SD) length of stay was 35.3 +/- 18.5 days and the range was 3-113 days. Whereas in the pre-accreditation period the mean (SD) length of stay was 41.1 +/- 29.5 days and the range was 1-167 days. The difference was statistically significant (P = 0.026).
Conclusion: Accreditation reduces excess LOS and contributes to improving the quality of psychiatric inpatient care and access to psychiatric beds.
