Antibiotic prescribing among inpatients with infectious and non-infectious indications in obstetrics and gynecology departments at two tertiary care hospitals in Central India
Abstract Background: Patients in departments such as obstetrics and gynecology (OBGY) are at high risk of life-threatening infections, thus are prescribed antibiotics extensively. Use of antibiotics leads to increasing antibiotic resistance. Antibiotic surveillance is one of the cornerstones to combat antibiotic resistance. However, hospital-based, department specific surveillance data of prescribed antibiotics are scarce especially in low- and middle-income countries. Aim: To describe and compare antibiotic prescribing patterns among the inpatients at OBGY departments of two tertiary care hospitals, one teaching (TH) and one non-teaching (NTH) in Central India. Methods: Data of all inpatients was collected manually for three years and analyzed using demographics, length of hospital stay, diagnoses and prescribed antibiotics including dose, duration, and frequency and defined daily dose per 1000 inpatients were calculated. The patients were divided into, infectious and non-infectious categories and further into surgical, non-surgical and possible surgical indications. The data was coded based on the Anatomical Therapeutic Chemical classification system and the International Classification of Disease system version-10. Results: Of the total 5558 admitted patients, 2044 (81%) in the TH and 2567 (85%) in the NTH received antibiotic treatment (p<0.001). In both hospitals, a majority of the patients with surgical indications were prescribed antibiotics (87% to 100%). Prescribing of the fixed-dose combinations of antibiotics (FDCs) and use of brand names was more common at the NTH then at the TH. A majority of the inpatients who neither had surgery nor had any confirmed bacterial infection also received antibiotic prescriptions (TH-71%, NTH-75%). Overall, higher DDD/1000 patients were prescribed in the TH compared to the NTH in both categories. Conclusions: More frequent prescribing of broad-spectrum antibiotics including FDCs and higher brand-name prescribing at the NTH compared to the TH is a point of concern. Antibiotics prescribed to the inpatients having non-bacterial infection indications is another point of concern and requires urgent action. Investigation of underlying reasons for prescribing antibiotics for unindicated diagnoses and the development and implementation of antibiotic stewardship programs are recommended measures to improve the prescribing of antibiotics.
