Outpatient prescribing trends, rational use of medicine and impact of prescription audit with feedback at a tertiary care centre in India

Evaluating drug use patterns among paediatric outpatients in Burundi

Background

Rational prescribing is key to optimising therapeutic outcomes and avoiding risks associated with irrational use of medicines. Using WHO drug use indicators, this study evaluated drug use patterns among paediatric outpatient encounters at Primary Healthcare Centers (PHCs) in Bujumbura Mairie, Republic of Burundi.

Methods

Descriptive cross-sectional research assessed paediatric medicine use in 20 PHCs. From 8 February to 7 April 2023, 800 randomly selected paediatric encounters' 2022-year data were retrospectively collected. Data for specific facility indicators were prospectively collected. SPSS 23 was used to analyse data.

Results

800 outpatient child encounters were analysed, 48.4% female and 51.6% male. The mean number of medicines per encounter was 2.4(±0.99). The injection rate was 9.9%. Overall, 78.8% of generics and 85.2% of essential medicines were prescribed. Results show drug prescribing differences between private and government PHCs (p < 0.001). All PHCs studied had no standard treatment guidelines (STGs), while 50% had an essential medicine list (EML) and 85% of key medicines were available.

Conclusion

Poor prescribing practices were found indicating the need for interventions to promote good drug use practices. A large study at a national scale is required to provide a more comprehensive understanding of the overall drug use practices.

OBJECTIVE

Evaluate the feasibility of monitoring the quality of use of medicines in health institutions in countries of the Region of the Americas by means of rational prescription indicators.

METHODOLOGY

A quantitative study of the use of medicines was conducted during the period 2016-2018. Rational prescription indicators were developed and selected in accordance with international reference values and the best available evidence for: 1) anti-inflammatory drugs: prescription of ibuprofen and/or naproxen as a percentage of all prescribed non-steroidal anti-inflammatory drugs; 2) oral antidiabetics: metformin as a percentage of all prescribed antidiabetics, and metformin and/or sulfonylureas as a percentage of all prescribed antidiabetics; 3) insulins: crystalline insulin and NPH as a percentage of total prescribed insulins; and 4) antihypertensive drugs: angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs-II), and thiazide diuretics as a percentage of all prescribed antihypertensives. The defined daily dose (DDD) per 1 000 inhabitants was used as a measure of consumption per institution.

RESULTS

Prescription of metformin as a percentage of all antidiabetics was lower than the value of the reference indicator (27.9%-67.6% vs. 88%), while the prescription of metformin and/or a sulfonylurea was comparable with that value (80.9%-97.5% vs. 88%). The values of NPH, crystalline, and NPH/crystalline insulin in relation to all prescribed insulins were variable with respect to the reference indicator (37.1%-100% vs. 75%). Prescription of ibuprofen and naproxen was below the value of the indicator (20%-50% vs. 80%). The percentage of ACE inhibitors, ARBs, and thiazides with respect to all antihypertensives ranged from 65.2%-77.2% to 65%, consistent with the value of the proposed indicator.

CONCLUSIONS

The feasibility of applying the selected and constructed indicators of rational prescription was demonstrated. These indicators provide useful information for analyzing the quality of prescription in health institutions in countries in the Region and are a useful tool for periodically monitoring it.
