Use of official health services often remains low despite great efforts to improve quality of care. Are informal treatments responsible for keeping a number of patients away from standard care, and if so, why? Through a questionnaire survey with proportional cluster samples, we studied the case histories of 952 children in Bandiagara and Sikasso areas of Mali. Most children with reported uncomplicated malaria were first treated at home (87%) with modern medicines alone (40%), a mixture of modern and traditional treatments (33%), or traditional treatment alone (27%). For severe episodes (224 cases), a traditional treatment alone was used in 50% of the cases. Clinical recovery after uncomplicated malaria was above 98% with anytype of treatment. For presumed severe malaria, the global mortality rate was 17%; it was notcorrelated with the type of treatment used (traditional or modern, at home or elsewhere). Inthe study areas, informal treatments divert a high proportion of patients away from officialhealth services. Patients’ experience that outcome after standard therapeutic itineraries isnot better than after alternative care may help to explain low use of official health services.
We need to study whether some traditional treatments available in remote villages should beconsidered real, recommendable first aid.

3. Results
Information to the local people and respect of traditionaletiquette resulted in a good acceptance of the survey: fromthe 483 households in the Bandiagara region and 469 house-holds in the Sikasso region, nobody refused to answer thequestionnaire, so the global response rate was 100%; somequestions, however, were not answered by 100% of respon-dents, as will be mentioned below.
Unless otherwise mentioned, results presented here are derived from pooled records from both regions (Finkolo andKendi´ e areas). Similarities in sample sizes and results justify Local designations of uncomplicated and severe malaria were in fairly close agreement with definitions based on clin-ical criteria and used in local dispensaries and health centres(86% agreement in Bandiagara, 98% in Sikasso region), thelatter being used for correlation analyses below.

4. Discussion
Progress of patients after different treatments The objective of this study was to examine how and why use of home- or village-based treatments may keep patientsaway from official health services. For this, we studied ther- apeutic practices and subsequent patient progress in pre- sumed malaria episodes in remote areas.
Self-medication (modern drugs or traditional medicine) was the most frequent type of first treatment sought, even for suspected severe malaria. For severe malaria, traditional medicine was the only treatment used in half the cases.
After uncomplicated malaria, total recovery was above 98% with any type of treatment. For severe malaria, the global mortality rate was 17% and did not significantly differ with the type of treatment used. Some local products were sys- tematically associated with good clinical outcome and found to have medium to high in-vitro antiplasmodial activity.
Severity in itself was not a reason for seeking modern health care: only 24% of patients with severe malaria chosemodern medicine as their first option, whereas 41% of thosewith uncomplicated malaria did so. One reason for this couldbe that severe malaria is more often related to supernatu- traditional treatment, all cases: 73 vs. 66%, P = 0.02) and ral events (Another explanation could be the when the mother had studied in the ‘madrasa’ or Koranic perceived effectiveness of traditional medicine for severe school (85% sought modern treatment, vs. 67% among those malaria and experience of high case-fatality rate in the hos- who had no schooling, P = 0.004).
