Mobile phone images might be useful in after-hours triage of primary care. We conducted a study to identify population access to mobile phone cameras and to assess the clinical usefulness of mobile phone cameras. The survey was conducted among 480 patients attending two rural New Zealand practices. There were significantly more Maori owners compared to non-Maori (P = 0.002). Age was a significant factor influencing the ownership of mobile phones. We also conducted a clinical quiz among health professionals to assess how the provision of images on a mobile phone and on CD-ROM (to simulate the image that would be seen if email was used to transmit the images) influenced diagnostic confidence. Ten photographable clinical conditions were used to quiz 30 health professionals who were randomized into three groups of 10 each on diagnostic confidence. Images were found to significantly increase diagnostic confidence in all cases except one. It appears that mobile phone cameras are generally acceptable to patients and likely to be of practical use to rural practitioners in a range of clinical scenarios.

Objective: To examine whether data on the clinical profiles of psychiatric service users can inform the claim that Māori in the New Zealand community have an increased rate of bipolar disorder., Method: The standardized recordings of a variety of clinical phenomena previously collected in a New Zealand study of psychiatric service users was extracted for those persons who were diagnosed with a bipolar mental disorder. The individual clinical phenomena were then compared by ethnicity., Results: The most dramatic result was the increased recording of high levels of overactivity or disruptive aggressive behaviour in Māori compared with European in psychiatric service users, despite which, the rates of the disorder did not significantly differ by ethnicity., Conclusion: In the community survey lay raters were deciding on the presence or absence of phenomena including hyperactivity without the contextual knowledge that clinicians use. It is possible that the Composite International Diagnostic Interview decision tree was being fed an excessive amount of that criterion.

Objective: The present accepted classificatory systems (ICD-10 and DSM-IV) represent the culmination of 100 years of post-Kraepelinian evolution. The present paper reports on a study to ascertain the views of New Zealand psychiatrists on their requirements of a classificatory system, and their opinions on those currently in use., Method: An anonymous postal survey of 542 psychiatrists and trainees was undertaken in New Zealand., Results: A total of 235 questionnaires were returned, completed. New Zealand psychiatrists primarily use DSM-IV and do so because that is what they were taught on. They make relatively limited use of the multiaxiality. The purposes of classificatory systems that they value most highly are reliable interclinician communication, and to inform patient management planning. The two purposes they valued least were usefulness for a national statistical base, or to indicate prognosis., Conclusions: New Zealand psychiatrists' views are consistent with some of the stated objectives of ICD-10 and DSM-IV, but there is significant diversity in the former and over-ambition in the latter, with much to be resolved.
