    Audit of the quality and cost of acute inpatient stroke care in the general medical wards at Groote Schuur Hospital
    (2016) Viljoen, Charle André; De Villiers, Linda
    Introduction: Stroke is the leading cause of death and disability amongst South Africans older than 60 years. The majority of stroke patients in South Africa are managed in general medical wards where little is known about the quality and cost of care. The aim of this study was to determine the cost of stroke care and to identify factors associated with increased expense , as well as to evaluate the quality of stroke care in general medical wards in order to identify areas where quality of care could be improved. Methods: We conducted a retrospective folder review of all acute stroke admissions to the general medical wards at Groote Schuur Hospital from 1 January to 31 December 2012. Patients younger than 45 years and those that received thrombolysis were excluded. The hospital's finance department provided the bed costs, as well as expenditure on consumables, pharmacy, laboratory and radiology for each subject. The quality of care was measured according to the South African Stroke Guidelines. Results: The inpatient care of 261 patients was evaluated. Although neuroradiology was performed on 95% of patients, carotid duplex Doppler ultrasonography and echocardiography were not often done. Although all patients with ischaemic stroke received inpatient antiplatelet or anti - coagulation therapy, not all risk factors were adequately addressed on discharge. The median cost of a stroke admission was R19,072.07 (IQR R10,899.85 to R27,789.43 ). The strongest correlation with cost 12 was with length of stay (LOS), r = 0.9977. The median LOS was 6 days (IQR 3 to 9 days). Using non -¬‐ parametric univariable analysis, clinical factors prolonging LOS were previous stroke ( P = 0.0 2 8) and inpatient complications: fever ( P < 0.0 0 1), urinary tract infections ( P < 0.0 0 1) and acute kidney injury ( P < 0.0 0 1) . The LOS increased as the number of inpatient complications increased (P = 0.059). Mortality was 20% and 68% of patients experienced at least one medical complication during admission. Fever and pneumonia were predict ors of death. Pneumonia was less prevalent amongst patients who were mobilised early (P = 0.002). Early nutritional support was beneficial in reducing the incidence of acute kidney injury (P < 0.001). The median LOS was significantly prolonged by delaying speech therapy (P < 0.001), nutritional support (P < 0.01), physiotherapy (P < 0.01) and occupational therapy (P < 0.001). Discharge to inpatient rehabilitation centres significantly prolonged LOS as compared with patients discharged home (P < 0.001). Conclusions: This is the first study evaluating the cost of acute stroke care in South Africa. Length of stay was the greatest determinant of cost. Improving the quality of care to reduce the number of complications, early referral to allied health professionals and effective discharge planning would result in shorter length of hospital stay and therefore cost saving. There is a need for increased access to stroke unit beds, albeit dedicated stroke beds in the general medical wards, to ensure specialised nursing care and early inpatient rehabilitation to reduce the number of inpatient complications, as well as implementation of protocols to allow for better adherence to national guidelines.

    Stroke outcomes in a socio-economically disadvantaged urban community
    (2011) De Villiers, Linda; Badri, Motasim; Ferreira, Monica; Bryer, Alan
    AIMS: To determine survival, disability and functional outcomes of stroke patients following their discharge from an acute stroke unit in an urban community with limited rehabilitative resources. METHODS: Stroke patients were recruited from a district hospital in Cape Town and followed-up for 6 months. Clinical characteristics, demographic and socioeconomic data, and disability and function as measured by modified Rankin Score (mRS), modified Barthel Index (mBI) at recruitment and 3 follow-up visits, were recorded. RESULTS: The study included 196 patients. Median age was 60 (IQR 51 - 69) years, 135 (68.9%) were female, 57.7% black, 42.3% coloured, and 45 (23%) died within 6 months. At discharge, median mBI score was 7 (IQR 3 - 12) and median mRS 4 (IQR 3 - 5). In the multivariate regression models, only function (mBI OR 0.88, 95% confidence interval (CI) 0.79 - 0.96, p<0.0001) and disability (mRS 0R 2.34, 95%CI 1.20 - 4.54, p<0.0001) were independently associated with risk of death. Shack housing was independently associated with moderate or severe disability (odds ratio 3.42, 95%CI 1.22 - 9.59, p=0.02). Despite limited rehabilitation resources, 67% of survivors had mild to moderate disability at 6 months. CONCLUSION: Apart from initial stroke severity, risk factors for poor survival were a severe disability category and the presence of impaired swallowing at discharge. Shack housing was independently associated with poor functional outcomes. These findings should be helpful in allocating home-based care and inpatient rehabilitation resources to high-risk groups to improve outcomes.
