要旨

Objectives:

The overuse of antibiotics for respiratory tract infections in primary healthcare in rural China is a particular challenge and is highly related to antibiotic resistance. Our research team designed a multi-component intervention focusing predominantly on health practitioners to reduce antibiotic prescriptions in rural communities of China. The effects of the intervention were evaluated through a randomised controlled trial. This study was conducted alongside the trial to develop a contextualised understanding of the implementation of the intervention and related influencing factors.

Design:

Qualitative process study nested in a randomised controlled trial, including observation and semi-structured interviews.

Setting:

Primary healthcare in rural China.

Participants:

27 health practitioners from township health centres assigned to the intervention arm.

Intervention:

A complex intervention to reduce antibiotic prescriptions in rural communities of China, which includes the following components: training for health practitioners, a public letter of commitment, patient leaflets, a decision support system and a peer support group.

Primary And Secondary Outcome Measures:

Not applicable.

Analysis:

Data were analysed using thematic analysis.

Results:

The overall multi-component intervention was described as useful in reducing antibiotic prescribing, with a particularly high acceptance and use of patient leaflets and the public letter of commitment among health practitioners. There were mixed views on the decision support system and peer support group. Practitioners reported usability-related barriers to using the decision support system during consultations. Practitioners did not understand the role or benefits of the peer support group and found it difficult to initiate group discussions, due to the lack of any existing clinical team at the primary care level.

Conclusions:

The multi-component intervention appears to be acceptable and useful in primary healthcare in rural China. Successful implementation requires a comprehensive understanding of the contextual characteristics of the setting. Interventions to reduce antibiotic prescribing in China in the future could consider wider stakeholders including patients, retail pharmacies and health authorities.

Trial Registration Number:

ISRCTN30652037 (01/12/2020).

Hypothesis: Accept or Fail to Reject?

The outcome of any hypothesis testing leads to rejecting or not rejecting the null hypothesis. This decision is taken based on the analysis of the data, an appropriate test statistic, an appropriate confidence level, the critical values, and P-values. However, when the evidence suggests that the null hypothesis cannot be rejected, is it right to say, 'Accept' the null hypothesis?
There are two ways to indicate that the null hypothesis is not rejected. 'Accept' the null hypothesis and 'fail to...

Antimicrobial Effectiveness

The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...
