Abstract
BACKGROUND: The TUNE-IN (The Use of VTE prophylaxis in relatioN to patiEnt risk profiling) study evaluated venous thrombo-embolism (VTE) risk assessment and prophylaxis in private medical and surgical inpatients in Gauteng Province, South Africa. The study concluded that of the 608 patients enrolled, 54.1% were clinically evaluated to be at risk for VTE. A VTE risk assessment model (RAM), the Caprini score, increased the rate to 74.6%. OBJECTIVES: TUNE-IN Wave 2, an extension of TUNE-IN, was conducted on a national level including the public sector, focusing on surgical inpatients. METHODS: The study was a national, prospective, non-interventional, multisite, epidemiological disease registry enrolling 453 surgical inpatients. The perceived clinical VTE risk, VTE risk score on Caprini RAM, VTE prophylaxis and clinical details were documented during a baseline visit. A bleeding risk score was provided. RESULTS: Of the cohort, 269 patients (59.4%) were assessed to be at risk for VTE before applying the RAM. All patients (100%), however, were at risk on the RAM score. Early mobilisation and assessment of the VTE risk as low were the most frequent reasons for non-prescription of prophylaxis. Only 15 patients in the private and 2 in the public sector were assessed as having a bleeding risk. Chemoprophylaxis differed between the healthcare sectors, with low-molecular-weight heparin predominating in the private sector and unfractionated heparin being prescribed only in the public sector. CONCLUSION: VTE risk assessment and prophylaxis need to improve in both the public and the private sectors. A formal RAM will improve identification of patients at risk of VTE.
