Background: Tuberculosis (TB) case detection in China has improved remarkably, partly benefiting from the reducing delay to TB care, whereas the timeliness of TB care in Malawi remains problematic.
Methods: This study investigates barriers hindering timely TB diagnosis in Malawi and China, and attempts to share the experience in high burden countries. A cross-sectional study on TB diagnostic delay was conducted among 254 Malawian and 146 Chinese TB patients.
Results: The medians of patient's delays were 22 and 20 days (p>0.05), and provider delays were 12 and 11.5 days (p>0.05) in Malawi and China, respectively. Malawian patients had a higher proportion (72.05% vs 67.12%) of patient's delay longer than 14 days (p=0.042), which was significantly associated with initial visits to lower-level health providers in the villages (aOR=1.989, 95% CI: 1.075-3.682), and patients conducting casual/piece work (aOR=3.318, 95% CI: 1.228-8.964). Initial healthcare visits at village level also led to longer provider delay in both Malawi (aOR=2.055, 1.211-3.487) and China (aOR=5.627, 2.218-14.276).
Conclusion: Establishing a good communication and referral mechanism between different levels of health facilities is crucial to timely TB diagnosis. China's experience on pro-poor interventions could be useful to its Malawian counterpart and other similar settings with high TB burden.
