Assessment of prescribing patterns of antibiotics using National Treatment Guidelines and World Health Organization prescribing indicators at the Ghana Police Hospital: a pilot study

Abstract

Introduction: irrational or inappropriate prescribing of antibiotics is a major problem in healthcare and leads to antibiotic resistance. There is the need to understand the prescribing patterns and antibiotic stewardship in health facilities to support appropriate antibiotic use. A study was carried out to evaluate prescribing pattern of antibiotics at the Ghana Police Hospital using National Standard Treatment Guidelines (STG) and World Health Organization (WHO) prescribing indicators.

Methods: a cross-sectional descriptive study was conducted at the Ghana Police Hospital. Data on prescriptions of antibiotics for both out-patients and in-patients was collected between December 2019 and March 2020. A pretested self-designed tool was used for data collection. All sampled prescriptions were assessed for appropriateness using the STG of 2017 and WHO “AWaRe” classification. The criteria used in assessment included dose, frequency, duration of treatment and choice of antibiotic prescribed for disease condition. Descriptive statistics were used in data analysis.

Results: a total of 184 patient prescriptions (286 antibiotics) were included in this study. Results showed that antibiotics were mostly prescribed for dental and dental-related conditions (20.7%) and obstetric post-delivery prophylaxis (18.1%). Appropriateness of indicators for antibiotics prescribed assessed ranged between 89.2% to 97.6%. The most frequently prescribed antibiotics were metronidazole (25.9%), amoxicillin with clavulanic acid (22.0%), amoxicillin (16.4%) and ciprofloxacin (10.1%). Based on WHO “AWaRe” classification, the “access” group of antibiotics (74%) was the most prescribed, followed by “watch” group (24%). There were no antibiotics prescribed from the “reserve” group of antibiotics and another 2% that was not part of AwaRe classification.

Conclusion: study revealed that the level of appropriateness for prescribing indicators assessed was relatively high and majority of prescribed antibiotics were from the “access” and “watch” group. These observations suggest responsible prescribing of antibiotics at the Ghana Police Hospital and effective antibiotic stewardship should be sustained and improved.
