Clinical coaching in primary care: Capable of improving control in patients with type 2 diabetes mellitus?

Aims: Few clinical coaching studies are both endorsed by real cases and focused on reducing suboptimal diabetes control. We evaluated the effectiveness of coaching on improving type 2 diabetes goals after 3 years of implementation in primary care. Methods: A cross-sectional study with follow up was conducted during 2008-2011. Coaching consisted of guiding family doctors to improve their clinical abilities, and it was conducted by a medical doctor trained in skill building, experiential learning, and goal setting. Effectiveness was assessed by means of fasting plasma glucose and glycosylated hemoglobin outcomes. The main analysis consisted of 1 x 3 and 2 x 3 repeated measures ANOVAs. Results: A significant coaching x time interaction was observed, indicating that the difference in glucose between primary care units with and without coaching increased over time (Wilks' lambda multivariate test, P<0.0001). Coaching increased 1.4 times (95%CI 1.3, 1.5) the possibility of reaching the fasting glucose goal after controlling for baseline values. There was also a significant improvement in glycosylated hemoglobin (Bonferroni-corrected p-value for pairwise comparisons, P<0.0001). Conclusions: A correctible and even preventable contributing component in diabetes care corresponds to physicians' performance. After 3 years of implementation, coaching was found to be worth the effort to improve type 2 diabetes control in primary care. (C) 2015 Primary Care Diabetes Europe. Published by Elsevier Ltd.
