Understanding hospital antimicrobial prescribing decisions and determinants of uptake of new local antimicrobial prescribing guidelines in the Laos

TL;DR

This study explores how doctors in Laos decide to prescribe antibiotics and how they use new guidelines to improve appropriate antimicrobial use.

Contribution

The study identifies key factors influencing antibiotic prescribing decisions and barriers to guideline uptake in Laos.

Findings

Lao prescribers rely heavily on clinical judgment and face challenges like antibiotic shortages and long lab result wait times.

Most prescribers found the new guidelines useful but did not use them frequently due to familiarity with treatment recommendations.

Improving antibiotic knowledge, ensuring drug availability, and leadership support are key to better antibiotic use.

Abstract

Antimicrobial use in the Laos is among the highest in the Southeast Asia region. The first Lao comprehensive antimicrobial prescribing guidelines have been available since 2021. This study explored the determinants of antibiotic prescribing decisions and how the new prescribing guidelines were being used.

In August 2022, in-depth interviews were conducted with 16 Lao prescribers from two hospitals. Participants were questioned about their prescribing behaviours, attitudes to guidelines, how they learned about the guidelines and factors influencing their uptake. The interviews were audio-recorded, transcribed, and translated into English. Thematic analysis of the transcripts was conducted.

Lao prescribers considered multiple factors before deciding to prescribe antibiotics to their patients. The most common factor was based on the clinical judgement of the prescribers. Lack of certain antibiotics and turnaround times of laboratory results were the main challenges to prescribing antibiotics appropriately. The majority of participants were satisfied with the guidelines, regarding them as comprehensive, simple and convenient. However, most participants admitted that they did not access the guidelines very often. The main reason was that they could remember the treatment recommendations because they treat similar diseases on a daily basis. Improving antibiotic knowledge was the most common recommendation in order to improve the appropriate use of antibiotics. Raising awareness of the guidelines and promoting their use should also be considered. In addition, heads of the wards, and policy and implementation leaders, should support, monitor and feedback their use to encourage all prescribers to follow the guidelines.

Several factors contribute to enhancing appropriate antibiotic prescription. Key factors for improving antibiotic prescription include enhancing prescribers' clinical knowledge, ensuring access to essential antibiotics, utilizing point-of-care diagnostics while waiting for culture and susceptibility testing results, and updating guidelines regularly. Health leaders must get involved to promote their use.

In Laos, antibiotic use is high compared to other Southeast Asian countries. In 2021, the first guidelines for prescribing antibiotics were introduced in Laos. This study aims to explore what influences doctors’ decisions in prescribing antibiotics and how they used the new guidelines.

In August 2022, we conducted in-depth interviews with 16 doctors in two Lao hospitals. We asked them how they decided which antibiotics to give, what they thought about the guidelines, how they found the guidelines and what could make them use the guidelines more. We recorded, transcribed, and translated the conversations. Then, we identified common themes and patterns.

Before giving antibiotics, doctors in Laos considered many things. The most important thing was their own judgment based on their medical knowledge. Not having some antibiotics and waiting long times for the laboratory results were the main issues that made it challenging for doctors to prescribe antibiotics. Most interviewees liked the guidelines. They found the guidelines easy to understand and useful. Many of them said that they did not use the guidelines a lot. The main reason was that they remembered the treatment recommendations because they treat similar diseases every day. The most common suggestion to use antibiotics better was to learn and understand more about them. Also, leaders of hospital departments and those in charge of making rules should help, keep an eye on the use, and give feedback to make sure everyone who prescribes antibiotics uses the guidelines.

To make sure doctors prescribe antibiotics better, they need to know and understand more about infectious diseases, have easy access to essential antibiotics, have access to quick diagnostic tools, and regularly update the guidelines with support from the leaders.
