Retrospective case note review of patients brought to Ipswich emergency department under mental health emergency examination orders: does intoxication alter outcome?

OBJECTIVE

To alter staff perceptions, and to examine alternative management processes for intoxicated patients brought to Ipswich ED under mental health emergency examination orders by comparing disposition outcomes with non-intoxicated patients.

METHODS

Consultation-Liaison mental health nursing staff completed surveys on all patients assessed under emergency examination orders over a 6 month period in 2008. Patients were classified as intoxicated if they recorded alcometer readings of greater than 0.05%, or self-reported drug use during the events leading to their transport to the ED. Outcomes were retrospectively collated with entries in Clinical Liaison nursing logbooks. Outcome measures recorded were rates of admission, outpatient referrals to the Integrated Mental Health Service, follow up by other community services or no follow up. Differences in outcomes for intoxicated and non-intoxicated patient groups were tested for significance using χ(2) or Fisher's exact test.

RESULTS

One hundred and sixty-eight cases were included in the audit. No cases were excluded. Sixty patients were identified as intoxicated. The age and sex distributions were similar between intoxicated and non-intoxicated patients. There were no significant differences in admission or referral rates. The average length of assessment time in the ED was longer in the intoxicated group.

DISCUSSION

This audit showed similar outcomes for both patient groups contrary to the perceptions expressed by ED staff in informal surveys. The admission and referral rate for both groups indicate they are an at-risk population. The admission rate of 16% has led to this department negotiating alternative accommodation for patients while they sober up.
