Hypothesis

Does a computerised decision support system achieve more than academic detailing alone in improving antibiotic prescribing for community acquired pneumonia?

Conclusion

The use of a computerised decision support system led to better antibiotic prescribing practices than academic detailing alone.

Supporting Evidence

  • The odds ratio for concordant therapy in the academic detailing period was OR = 2.79.
  • The odds ratio for the computerised decision support period compared to the academic detailing period was OR = 1.99.
  • Concordant antibiotic prescribing improved significantly during the computerised decision support period.

Takeaway

Doctors used a computer program to help them choose the right antibiotics for pneumonia, and it worked better than just talking to them about it.

Methodology

A time series analysis comparing antibiotic prescribing behavior over three periods: baseline, academic detailing, and computerised decision support.

Potential Biases

Potential bias due to the lack of randomization and the influence of time on prescribing behavior.

Limitations

The study did not include a separate control group and relied on the same clinicians at different time points.

Participant Demographics

Patients diagnosed with community acquired pneumonia in an urban adult tertiary teaching hospital.
