Antimicrobial use by WHO methodology at primary health care centers: a cross sectional study in Punjab, Pakistan

To investigate the antimicrobial (AM) use and prescribing patterns at primary health care centers (PHCCs) in Punjab, Pakistan.

A cross-sectional study was designed according to the World Health Organization (WHO) methodology for AM usage from January, 2017 to June, 2017. Standard data collection forms designed by the WHO were used to collect the data from 32 PHCCs (16 rural healthcare centers (RHCs) and 16 basic health units (BHUs)) in Punjab province of Pakistan. PHCCs were randomly selected from 8 main cities. The study sample consisted of prescription records of 6400 outpatients (200 prescriptions records from each PHCC) and 800 inpatients (25 inpatient records from each PHCC). Data of the year 2016 were collected retrospectively by using systematic random sampling technique and analyzed through SPSS.

Among the hospital indicators, standard treatment guidelines (STGs) regarding the infectious diseases were not available in PHCCs. Number of days during which key AMs were out of stock was 12.1 days per month (range = 3.1-19.2). Out of total PHCC medicines costs, expenditures on AMs were 26.2% (range = 17.1-39.0). In case of prescribing indicators, the average number of AMs per prescription was 1.4 (range = 1.1-1.7), percentage of prescriptions prescribed with AMs was 81.5% (range = 68.9-89.1) and duration of AM treatment on average was 5.1 days per patient (range = 3.3-6.4). Average cost of prescribed AMs per patient was 1.3 USD (range = 0.6-4.3). The PHCCs prescribed a median of 5 (range = 3-9) types of AMs, including 10 (range = 5-15) individual agents. Out of 79.3% prescriptions of outpatients prescribed with AMs, only 16.4% were properly prescribed. Out of 100% prescriptions of inpatients prescribed with AMs, 12.1% were properly prescribed. Out of all the AM prescriptions 23.6% contained penicillins, 20.1% contained cephalosporins and 19.4% contained fluoroquinolones Metronidazole (18.0%), ciprofloxacin (16.5%) and co-amoxiclav (14.3%) were most commonly prescribed AMs.

In PHCCs, AMs were prescribed more frequently. However large proportions of these prescriptions were inappropriate. Continuous education and training of medical staff and cost effective policies could play an important role in promotion of rational use of AMs.
