Leadership, work environment and caries prevention - what is good for the staff, is also good for the patients.

Objectives: Dental caries is a health problem that can be prevented. The aim of this study is to analyse if the quality of leadership, in Swedish Public Dental Health clinics, influences the extent to which patients with caries receive preventive care, and if any such effect is mediated through a collaborative work climate, clear role expectations and a low average level of burnout among staff.

Methods: The multilevel cross-sectional design includes work environment data from surveys of 75 general public dental clinics, register-based data on preventive measures provided to 5398 patients who received a dental filling due to a caries diagnosis, and patient demographics. Using a multilevel path analysis with logistic regression, we tested a model with one direct and three indirect pathways, controlling for the potential confounding effect of patient demographic factors.

Results: Leadership quality, as assessed by the staff at the clinic, was associated with increased odds of patients with caries receiving prevention, controlling for patient demographic factors. Leadership quality was also positively related to a collaborative work climate, clear role expectations and a low average level of burnout among staff. Against expectations, however, no indirect effect from leadership quality on prevention through the other work environment factors was found.

Conclusions: In conclusion, the quality of leadership in Swedish Public Dental Health clinics was positively related to a good work environment for staff and to delivery of preventive care to patients experiencing caries.
