    Crisis discharges and readmission risk in acute psychiatric male inpatients
    (BioMed Central, 2008-06) Niehaus, Dana J. H.; Koen, Liezl; Galal, Ushma; Dhansay, Khalid; Oosthuizen, Piet P.; Emsley, Robin A.; Jordaan, Esme
    Background: Severe pressures on beds in psychiatric services have led to the implementation of an early ("crisis") discharge policy in the Western Cape, South Africa. The study examined the effect of this policy and length of hospital stay (LOS) on readmission rates in one psychiatric hospital in South Africa. Methods: Discharge summaries of adult male patients (n = 438) admitted to Stikland Psychiatric Hospital during 2004 were retrospectively examined. Each patient's clinical course was then analysed for the period between January 1st, 2004, and August 31st, 2006. Results: Although shorter LOS was associated with decreased readmission rates, the effect of crisis discharges was far more powerful. Patients discharged as usual had a far lower risk of readmission than those discharged due to bed pressures (i.e. crisis discharge). Conclusion: Increased risks associated with the early discharge policy necessitate the urgent review of the current management of bed shortages in this inpatient facility. The strengthening of community initiatives, particularly assertive outreach could be a way forward.

    The rise of assertive community interventions in South Africa : a randomized control trial assessing the impact of a modified assertive intervention on readmission rates; a three year follow-up
    (BioMed Central, 2014-02) Botha, Ulla A.; Koen, Liezl; Galal, Ushma; Jordaan, Esme; Niehaus, Daniel J. H.
    Background: Many countries have over the last few years incorporated mental health assertive interventions in an attempt to address the repercussions of deinstitutionalization. Recent publications have failed to duplicate the positive outcomes reported initially which has cast doubt on the future of these interventions. We previously reported on 29 patients from a developing country who completed 12 months in an assertive intervention which was a modified version of the international assertive community treatment model. We demonstrated reduction in readmission rates as well as improvements in social functioning compared to patients from the control group. The obvious question was, however, if these outcomes could be sustained for longer periods of time. This study aims to determine if modified assertive interventions in an under-resourced setting can successfully maintain reductions in hospitalizations. Methods: Patients suffering from schizophrenia who met a modified version of Weidens’ high frequency criteria were randomized into two groups. One group received a modified assertive intervention based on the international assertive community treatment model. The other group received standard care according to the model of service delivery in this region. Data was collected after 36 months, comparing readmissions and days spent in hospital. Results: The results demonstrated significant differences between the groups. Patients in the intervention group had significantly less readmissions (p = 0.007) and spent less days in hospital compared to the patients in the control group (p = 0.013). Conclusion: Modified assertive interventions may be successful in reducing readmissions and days spent in hospital in developing countries where standard care services are less comprehensive. These interventions can be tailored in such a way to meet service needs and still remain affordable and feasible within the context of an under-resourced setting.

    Screening for hypothalamic-pituitary-adrenal axis suppression in asthmatic children remains problematic : a cross-sectional study
    (BMJ, 2013) Zollner, Ekkehard Werner; Lombard, Carl J.; Galal, Ushma; Hough, Stephen; Irusen, Elvis M.; Weinberg, Eugene
    Objective To determine which parameter is the most useful screening test for hypothalamic–pituitary–adrenal suppression in asthmatic children. Design Cross-sectional study. Setting Paediatric allergy clinics in Cape Town, South Africa. Participants 143 asthmatic children of mostly mixed ancestry, aged 5–12 years. Outcome measures Primary outcome measures included Spearman correlation coefficients (r) calculated between the postmetyrapone (PMTP) serum adrenocorticotropic hormone (ACTH), 11-deoxycortisol (11DOC), 11DOC+ cortisol (C) and height, weight, height velocity, weight velocity, change in systolic blood pressure from supine to standing, early morning urinary free cortisol (UFC), morning C, ACTH and dehydroepiandrosterone sulfate (DHEAS). Secondary outcome measures were the receiver operating characteristics (ROC) curve and the diagnostic statistics for the most promising test. Results All screening variables were weakly correlated with the three PMTP outcomes. Only DHEAS and UFC (nmol/m2) were statistically significant—DHEAS for PMTP ACTH and 11DOC (r=0.20, p=0.025 and r=0.21, p=0.017); UFC (nmol/m2) for PMTP 11DOC and 11DOC+C (r=0.19, p=0.033 and r=0.20, p=0.022). The area under ROC curve for DHEAS in the 5-year to 9-year age group was 0.69 (95% CI 0.47 to 0.92). At DHEAS cut-off of 0.2 µmol/L: sensitivity=0.88 (CI 0.47 to 1.00), specificity=0.61 (CI 0.42 to 0.78), positive predictive value=0.37 (CI 0.16 to 0.62), negative predictive value=0.95 (CI 0.75 to 1.00), accuracy=0.67 (CI 0.50 to 0.81), positive likelihood ratio=2.26 (CI 1.35 to 3.78), negative likelihood ratio=0.20 (CI 0.03 to 1.30). Conclusions No parameter is useful as a universal screening test. DHEAS may be suitable to exclude HPAS before adrenarche. Further research is needed to confirm these findings and identify factors, for example, genetic that may predict or protect against HPAS.
