Abstract:
In South Korea, public–private mix (PPM) was launched in 2011. This retrospective cohort study sought to determine the rate of loss to follow-up (LTFU) among drug-susceptible tuberculosis (DS-TB) patients in all nationwide PPM institutions, and the risk factors for LTFU. National notification data for DS-TB patients diagnosed between August 2011 and July 2014 in PPM institutions were analysed. Determination of LTFU included detection of instances where patients were transferred out, but when they did not attend at other TB centres in the following two months. Univariable and multivariable competing risk models were used to determine risk factors for LTFU. 73,046 patients with 78,485 records were enrolled. Nominally, 3426 (4.4%) of records were LTFU. However, after linking the multiple records in each patient, the percentage of LTFU was 12.3% (9004/73,046). Risk factors for LTFU were: being foreign-born (3.13 (95% CI 2.77–3.53)), prior LTFU (2.31 (2.06–2.59)) and greater distance between the patient’s home and the TB centre (4.27 (4.03–4.53)). ‘Transfer-out’ was a risk factor in patients managed by treatment centres close to home (1.65 (1.49–1.83)), but protective for those attending centres further (0.77 (0.66–0.89)) or far-away (0.52 (0.46–0.59)) from home. By considering the complete picture of a patient’s interactions with healthcare, we identified a much higher level of LTFU than previously documented. This has implications for how outcomes of treatment are reported and argues for a joined-up national approach for the management and surveillance of TB patients, in nations with similar healthcare systems.
