The types of complaints from patients about their healthcare investigated by the NSW Commission were similar to those received by other patient complaint entities in Australia and worldwide. The application of a standard taxonomy to large numbers of complaints cases from different sources would enable the creation of aggregated data. Such data would have better statistical capacity to identify common safety and quality healthcare problems and so point to important areas for improvement. Some conceptual challenges in devising and using a taxonomy must be addressed, such as inherent problems in ensuring coding consistency, and giving greater weight to patient concerns about their treatment.

The residents maintained community tenure with significant improvement in quality of life and a reduction in medication, supported by a mental health system with adequate community resources. Issues regarding continuing rehabilitation and social integration need to be addressed. Further deinstitutionalization will require 24-h supervision for most initially and for some on a continuing basis. An ageing population will require specific age related medical and psychiatric services.

As cannabis use may precipitate relapse in this population, it is important to reduce these motivators of use. Clinician's must assess and treat these problems, thus reducing the need for patients to self-medicate with cannabis, and therefore reducing the risk of relapse.

Objective: To examine the reasons for cannabis use among individuals with psychotic disorders. Method: Forty-nine people with psychotic disorders in treatment with community health centres in Northern Sydney were interviewed to collect information about their experience of antipsychotic side-effects and their influence on cannabis use. Other information collected on cannabis use included: amount and frequency, effects of use and other general reasons given for use. Results: It was found that boredom, social motives, improving sleep, anxiety and agitation and symptoms associated with negative psychotic symptoms or depression were the most important motivators of cannabis use. Positive symptoms of psychosis and antipsychotic side-effects that were not associated with anxiety, were not important motivators of cannabis use. Conclusions: As cannabis use may precipitate relapse in this population, it is important to reduce these motivators of use. Clinician's must assess and treat these problems, thus reducing the need for patients to self-medicate with cannabis, and therefore reducing the risk of relapse.
