Abstract
CABRERA-PIVARAL, Carlos E.; CROCKER-SAGASTUME, René C.; ZAVALA-GONZALEZ, Marco A. and MUNIZ-MENDOZA, Priscilla. Educational intervention to improve the competence of Mexican physicians to provide nutritional management for diabetes mellitus type 2. Rev. salud pública [online]. 2018, vol.20, n.6, pp.711-717. Epub Oct 20, 2020. ISSN 0124-0064. https://doi.org/10.15446/rsap.v20n6.65550.
Objective
To evaluate the effect of a participative educational intervention on the clinical competence of Mexican family physicians regarding the nutritional management of patients with diabetes mellitus Type 2.
Materials and Methods
Quasi-experimental study with a before-and-after control group. Convenience sample included 60 family physicians distributed in two social security primary health care units, randomly selected: 30 in the "A" unit and 30 in the "B" unit. Unit "A" was assigned randomly as control group, and "B" unit as intervention group. The intervention consisted of a theoretical-practical course-workshop that lasted six months where real cases were discussed and solved. Clinical competence was evaluated by means of an instrument designed ex professo, with a maximum theoretical value of 100 and 94% reliability according to the Kuder-Richardson test. Medians of clinical competence were compared among groups, before and after intervention, using the Mann-Whitney U test, while frequencies distribution of clinical competence level were analyzed with the Kolmogorov-Smirnov test (p≤0.05).
Results
Overall medians and intervals for unit "A" were 28 (9-45) pre-intervention and 34 (11-51) pos-intervention, with before-after difference p>0.05; for unit "B", values were 32 (12-50) pre-intervention, 61 (36-82) pos-intervention, and before-after difference p≤0.05. No significant differences were found among groups pre-intervention (p>0.05), although they were observed pos-intervention (p≤0.05).
Conclusions
The educational intervention evaluated proved to improve, in a statistically significant way, the overall and by dimensions clinical competence level of Mexican family physicians for nutritional management of patients with diabetes mellitus type 2.
