Malaria overdiagnosis: is patient pressure the problem?

Area of Science:

• Tropical Medicine
• Pharmacology
• Public Health

Background:

• Over-prescription of antimalarials in Africa is a growing concern, especially with the introduction of more expensive drugs.
• Understanding the drivers of this overuse, such as patient demand, is crucial for effective drug stewardship.

Purpose of the Study:

• To investigate the extent to which patient demand influences antimalarial prescribing behavior in Tanzanian hospitals.
• To explore the relationship between patient expectations and clinician prescribing practices.

Main Methods:

• Observational study of outpatient consultations in five Tanzanian district hospitals.
• Exit interviews with patients/caretakers and interviews with clinicians.
• Data collected from 669 consultations and 326 patient interviews.

Main Results:

• Patients did not significantly demand antimalarials; occasional requests for malaria testing were noted.
• Clinicians rarely perceived patient demand for antimalarials and stated it would not alter their prescribing.
• Patient satisfaction was higher when diagnostic tests were performed, regardless of treatment outcome.

Conclusions:

• Patient demand is not the primary driver of antimalarial over-prescription in this setting.
• Engaging patients by aligning their expectations with test results presents an opportunity to enhance antimalarial prescribing.
