Quantification of factors contributing to length of stay in an acute psychogeriatric ward.
OBJECTIVE
To identify variables that predict length of stay (LOS) in an acute psychogeriatric ward; quantify psychiatric, medical and social factors that contribute to LOS; and identify factors that prolong LOS.


METHODS
Prospective audit of admissions over 12 months.


METHODS
Acute psychogeriatric ward in teaching hospital.


METHODS
73 consecutive patients with a total of 88 admissions.


METHODS
Main psychiatric, medical and social reasons for admission; Physical Health Schema; total LOS; number of days attributable to psychiatric, medical, social and treatment (non-response and adverse reactions) reasons; DSM-IV diagnosis; global clinical outcome; discharge living arrangements; discharge psychotropic medication.


RESULTS
Presence of depressive symptoms was the most common psychiatric reason for admission and carer stress the main social reason for admission. Principal diagnosis of major depression and carer stress were significant predictors of LOS and accounted for 24.3% of the variance (p < 0.0001). Physical health and psychiatric comorbidity were not able to predict LOS. The proportion of psychiatric, medical and social reasons involved in LOS varied significantly by principal diagnosis (p < 0.001). Almost 42% of bed days were attributable to delays--for medical, social (eg placement problems), treatment (adverse events, non-response) or hospital system reasons.


CONCLUSIONS
The quantification of factors contributing to LOS in an acute psychogeriatric unit allows for more accurate identification of issues that can be addressed to improve the efficiency of bed utilization.
