Automating individualized coaching and authentic role-play practice for brief intervention training

OBJECTIVES

Brief intervention helps to reduce alcohol abuse, but there is a need for accessible, cost-effective training of clinicians. This study evaluated STAR Workshop , a web-based training system that automates efficacious techniques for individualized coaching and authentic role-play practice.

METHODS

We compared STAR Workshop to a web-based, self-guided e-book and a no-treatment control, for training the Engage for Change (E4C) brief intervention protocol. Subjects were medical and nursing students. Brief written skill probes tested subjects' performance of individual protocol steps, in different clinical scenarios, at three test times: pre-training, post-training, and post-delay (two weeks). Subjects also did live phone interviews with a standardized patient, post-delay.

RESULTS

STAR subjects performed significantly better than both other groups. They showed significantly greater improvement from pre-training probes to post-training and post-delay probes. They scored significantly higher on post-delay phone interviews.

CONCLUSION

STAR Workshop appears to be an accessible, cost-effective approach for training students to use the E4C protocol for brief intervention in alcohol abuse. It may also be useful for training other clinical interviewing protocols.

Near lethal art--transorbital brain injury

Penetrative transorbital injuries put intracranial structures in peril. We present one such case where a low velocity transorbital injury resulted in traumatic temporal lobe injury, but with full recovery. Clinicians should be vigilant of intracranial complications of transorbital injuries.

Dissection of the carotid artery as a cause of fatal airway obstruction

Carotid artery dissection is a rare entity, and most cases are attributable to causative factors, which include trauma and local malignancy. The vast majority of dissections present with cerebral infarct; those few that present with local mass effect and respiratory compromise may deteriorate rapidly, requiring urgent resuscitation and consideration of endotracheal intubation, which is often dangerous and/or impossible. The case of a spontaneous internal carotid artery dissection in an otherwise healthy young man, leading to gross mass effect and eventual fatal airway obstruction, is presented here. The need for a high index of suspicion for cervical vascular injury in cases of neck injury (even trivial), known head and neck malignancy/irradiation, or coagulopathy is highlighted. Patients presenting with unilateral neck swelling and symptoms related to mass effect must be assumed to have progressive airway obstruction, and difficult intubation should be anticipated.

Patterns of drug use by participants in the Western Australian methadone program, 1984-1991

OBJECTIVES

To establish the extent to which participants in the WA methadone treatment program used opiates, cannabinoids, benzodiazepines, cocaine and amphetamines, and to define the pattern of such use over time. In addition, the relationships between methadone daily dose and the use of the various drug groups was examined.

DESIGN

A retrospective analysis of data from 1678 samples from urinalysis screening over 13 separate surveys between 1984 and 1991. A mean of 35.9% of patients in the program was sampled on each occasion with each patient contributing only one sample in any one survey. Analytical techniques used included enzyme-multiplied immunoassay, thin-layer chromatography and gas chromatography-mass spectrometry.

RESULTS

Methadone and/or its major metabolite were detected in most urine samples, indicating satisfactory compliance by patients. The detection of opiates increased from a mean of 27.1% of samples in 1984-1989 to a mean of 44.2% of samples in 1990-1991. Codeine or morphine were most frequently detected (94% of all opiate-positive samples) and were found together in 38.2% of opiate-positive samples. Detection of cannabinoids also increased from a mean of 45.2% of all samples during 1984-1987 to a mean of 56.4% of samples during 1990-1991. Benzodiazepines were found in a mean of 26.7% of samples but use was not time-related. Detection of amphetamine-class drugs doubled from a mean of 8.3% of all samples (mid 1989 to mid 1990) to 16.8% of samples (mid 1990 to mid 1991). The major representatives of the latter group were methylamphetamine (47.3% of amphetamine-positive urines), amphetamine (15.7%) and ephedrine/pseudoephedrine (44.6%). Opiate use was significantly lower (P < 0.05) in those patients taking more than 80 mg methadone/day. In addition, benzodiazepine use increased significantly (P < 0.05) with increasing methadone daily dose. There was no relationship between methadone daily dose and use of cannabinoids or amphetamines.

CONCLUSIONS

The increase in the use of opiates, cannabinoids and amphetamines over the period 1984-1991 occurred about four years after the adoption of a harm minimisation treatment philosophy by the WA methadone program. The high prevalence of codeine and morphine in opiate-positive urine samples strongly suggested the use of "home-bake" heroin. In addition, the data showed that methylamphetamine and ephedrine/pseudoephedrine were the most frequently used psychostimulants. Suppression of opiate use in those clients receiving more than 80 mg methadone/day was consistent with earlier studies. However, the significant increase in use of benzodiazepines with increasing methadone daily dose requires further study.
