RESUMEN
AIMS: To evaluate the results of a structured intervention in primary healthcare to improve type 2 diabetes management. METHODS: The intervention was implemented in 2011-2012 in two cities in the State of Pernambuco, Brazil, and evaluated in 2013 by interviewing healthcare professionals about their practices in all primary care facilities of these two cities (intervention group), and of two paired control cities (control group). Comparisons between the intervention and control groups were made using standard parametric tests. RESULTS: The percentage of professionals who measured adherence to treatment, developed educational actions to control high-risk situations or prevent complications, or declared that they "explained" the disease to the patients, was higher in the control group (p<0.05). Multidisciplinary involvement, requests for electrocardiograms and referrals to specialists were also more frequent in the control group (p<0.01). The only differences favoring the intervention group were the higher proportion of nurses (p<0.05) and community health workers (p<0.01) trained for diabetes management and a greater frequency of discussing the cases of diabetic patients at team meetings (p<0.01). CONCLUSIONS: These negative results raise questions about the effectiveness of actions aiming to improve diabetes management in primary care, and reinforce the need for careful evaluation of their impact.
