H. Guiscafre et al., FROM RESEARCH TO PUBLIC-HEALTH INTERVENTIONS .1. IMPACT OF AN EDUCATIONAL STRATEGY FOR PHYSICIANS TO IMPROVE TREATMENT PRACTICES OF COMMON DISEASES, Archives of medical research, 26, 1995, pp. 31-39
Errors in treating common diseases occur very frequently in primary he
alth care practice. While many of these mistakes are not life-threaten
ing, the costs of abuse in drug prescription may be greatly increased.
An educational strategy aimed to improve physicians' prescribing prac
tices for acute diarrhea (AD) and acute respiratory infection (ARI) wa
s developed as a research study, involving three medical care units. T
he strategy was largely based on promoting active participation of the
trainees in the whole process, including: (a) group participation in
a literature review of updated articles related to management of AD an
d ARI; (b) analysis of prescribing practices before the intervention;
(c) participation in the development of a clinical algorithm for the t
herapeutic management of these illnesses; and (d) discussion of the us
efulness of the algorithm during peer review committee meetings. Succe
ssful results of this intervention, as judged by the improvement of tr
eatment practices and the persistence of changes for up to 2 years aft
er the intervention, as well as its ease of application and low costs,
motivated its extension to a health District and a State. In these si
tes, the intervention was in charge of medical leaders from the clinic
s and medical heads of the local health systems, respectively. The ext
ension of the educational strategy was accompanied by a relative reduc
tion in AD from 46.7% to 6.5% and in ARI from 32.6% to 8.5%. However,
the benefit-cost ratio showed a dramatic increase when comparing resul
ts from the research study and from the State intervention, for both A
D (from 3.3 to 4.4) and ARI (from 16.2 to 21.6), for an overall net in
crease of 33.3%. Based on these results, the educational strategy was
adopted by the National Program for the Control of Diarrheal Diseases,
and was used to train public health physicians throughout the country
, from 1992 to 1994.
