An observational study of medication administration errors in old-age psychiatric inpatients.
BACKGROUND
Relatively little is known about medication administration errors in mental health settings.


OBJECTIVE
To investigate the frequency and nature of medication administration errors in old-age psychiatry. To assess the acceptability of the observational technique to nurse participants.


METHODS
Cross-sectional study technique using (i) direct observation, (ii) medication chart review and (iii) incident reports.


METHODS
Two elderly long-stay wards in an independent UK psychiatric hospital.


METHODS
Nine nurses administering medication at routine medication rounds.


METHODS
Frequency, type and severity of directly observed medication administration errors compared with errors detected by retrospective chart review and incident reports.


RESULTS
Using direct observation 369 errors in 1423 opportunities for errors (25.9%) were detected vs. chart review detected 148 errors and incident reports none. Most errors were of doubtful or minor severity. The pharmacist intervened on four occasions to prevent an error causing patient harm. The commonest errors observed were unauthorized tablet crushing or capsule opening (111/369, 30.1%), omission without a valid reason (100/369, 27.1%) and failure to record administration (87/369, 23.6%). Among the nurses observed, the error rate varied widely from no errors to one error in every two doses administered. Of the seven nurses who completed the post-observation questionnaire, all said they would be willing to be observed again.


CONCLUSIONS
Medication administration errors are common and mostly minor. Direct observation is a useful, sensitive method for detecting medication administration errors in psychiatry and detects many more errors than chart review or incident reports. The technique appeared to be acceptable to most of the nursing staff that were observed.
