Smith MPH mini-thesis, School of Public Health, University of the Western Cape. This descriptive and analytical mini-thesis aimed to explore systemic health service problems that are related to frequent readmission of persons suffering from severe mental illnesses to Valkenberg Hospital through a comparative study of perspectives of mental health service providers and consumers. Reduction of acute and chronic beds in the Associated Psychiatric Hospitals, Western Cape over the past decade has led to increasing pressure for beds and rapid inpatient turnover, many of these inpatients being ‘revolving door’ patients. Integration of mental health service into general health services, an intrinsic part of the comprehensive primary health care (PHC) approach in South Africa, is supposed to make mental health care more accessible to the public, therefore research into why patients are being frequently readmitted at secondary specialist level is indicated. Qualitative data was collected during September/ October 2004 from six in-depth interviews with service users and two focus groups with service providers. Emergent findings were that the health service platform provides insufficient protection to families against violence associated with mental illness, insufficient mental health promotion and psychosocial rehabilitation, insufficient community support systems with poor c ommunity tenure for mental health care users, care pathways need much improvement and staff resources across the mental health platform are inadequate to address the ‘revolving door’ problem. Resources have not been put in place at PHC level. As result of lack of comprehensive mental health care patients are rapidly revolving through Valkenberg Hospital. This indicates that deinstitutionalisation and devolvement of mental health care cannot work without provision of the necessary infrastructure at community level. It is hoped that this context specific, small-scale study will sensitise service providers, programme managers and inform policy makers to the root causes of frequent readmissions to Valkenberg Hospital with a view to informing further research and improving mental health service provision to the public.

Mental health, along with other health services in the Western Cape, was challenged with the necessity of rationalisation with the 1994 provincial health plan. A Provincial Cabinet Resolution in 1998, the result of public lobbying against Valkenberg Hospital closure, led to restructuring into the Associated Psychiatric Hospitals and reduction of psychiatric beds mostly through de-institutionalisation of long term patients but also closure of acute beds across the four psychiatric hospitals in the Western Cape. Consequently the acute psychiatric units at the four psychiatric hospitals in the Western Cape are cur rently experiencing a crisis with the unremitting influx of psychotic patients from the Metropole and rural areas, and neither staff nor bed capacity to admit more patients. The Healthcare 2010 plan for the Western Cape specifies that human resources be de volved together with patients to primary health care (PHC) level, but staff patient ratios are such that the staff capacity to devolve to PHC level does not exist at Valkenberg or the other Associated Psychiatric Hospitals (APHs), all of which are classified as secondary regional hospitals with specialist functions of psychiatric treatment. Although hospital beds have decreased, the number of acute admissions per annum to the hospital has increased. This is accounted for by the increased flow of population into the Western Cape as well as higher patient turnover. The higher the turnover of patients, the higher is 1 the cost of human resources and therapeutic drugs in respect of diagnosis, treatment, rehabilitation and discharge with sufficient medication. Mental health legislation makes provision for involuntary admission to designated health establishments of persons who are assessed as mentally ill and a danger to themselves or others. Therefore Valkenberg Hospital cannot refuse patients admission or put them on a waiting list in order to retain patients who are inadequately stabilised on treatment. Where further stabilisation of these patients who are discharged to PHC level then fails to take effect, rapid relapse and readmission within weeks of discharge is all too frequently the result. It could be that the ‘revolving door’ syndrome and high chronic morbidity is a cyclical effect of inadequate mental health services due to scarce resources at both hospital and PHC level. Whilst rectifying the problem of scarce resources may at this stage elude us, perhaps there is scope for improving referral pathways in the vulnerable transition period between Valkenberg Hospital and PHC level. It is important to establish how consumers can be treated effectively at community level and what impediments are experienced. National health policy of treatment at PHC level, and our mental health legislation are not contradictory policies. The new Mental Health Care Act 2002 emphasises the least coercive
