Background
This study aims to identify the extent to which current clinical practice in the treatment of common respiratory tract infections (RTIs) is consistent with presenting symptoms and microbiological characteristics at health care settings in rural Anhui Province and implications for future antibiotic stewardship.
Methods
The study was implemented in one village clinic and one township health center in each of four rural residential areas in Anhui Province, China. Observations, structured and semi-structured interviews in village clinics and township health centers were conducted to investigate antibiotic use. Sputum and throat swabs were collected for bacterial culture and susceptibility testing.
Results
A total of 1068 (51.0% males and 49.0% females) completed the study. Antibiotics were prescribed for 87.8% of RTI patients. Of all the specimens tested, 329 (30.8%) specimens were isolated with bacteria. The most frequently detected bacteria were K. pneumonia (24.15% in all specimens), H. influenza (16.19%), H. parainfluenzae (14.77%), S.aureus (5.11%), M. catarrhalis (3.41%) and S. pneumoniae (2.27%). The bacteria detection was associated with age (OR = 1.91), season (OR = 0.41 to 0.60), days since infection onset (OR = 1.54 to 1.81), and runny or blocked nose (OR = 1.39 to 1.61), cough with green or white sputum (OR = 1.47 to 1.59). Antibiotic use was only linked with limited non-specific clinical manifestations e.g., days since infection onset (OR = 0.53) and sore throat (OR = 1.64).
Conclusions
The study reveals that antibiotics prescription is still very common in rural China which is driven mainly by patient reassurance and other non-pathological factors rather than treatment of bacterial infections. The study establishes the feasibility of conducting microbiological testing outside Tier 2 and 3 hospitals in rural China.
