Role of management and human resource factors on matrix support in secondary oral health care in Brazil

Objectives To investigate the association between health management and human resource factors on matrix support (MS) in a nationally representative sample of Dental Specialty Centres (DSCs) in Brazil. Methods This survey included 1042 DSCs (Response rate = 94.99%) in the second cycle of the National Program for the Improvement of the Quality and Access to the Dental Specialty Centres (PMAQ‐CEO, in Portuguese) in 2018. Previously trained interviewers extracted information on MS, health management and human resources of the DSC by using a structured instrument. An MS score was created by adding the number of positive answers to the 10 MS questions. Negative binomial regression models were used to estimate the unadjusted and adjusted rate ratios (RR) and corresponding 95% confidence interval (CI). Results Of all the DSCs (n = 1042), 116 (11.1%) performed all 10 MS procedures. Those DSCs with a manager who had a higher education degree in the area of Public Health or Public Management (RR = 1.01, 95% CI, 1.01–1.02) and with human resources that received incentives, bonuses or financial awards for performance related to the PMAQ‐CEO result (RR = 1.01 95% CI 1.01–1.02) are more likely to perform MS, when compared to the reference categories. The DSCs that are more likely to perform MS include those that developed actions as a result of periodic planning and evaluation with confirmatory documentation (RR = 1.06, 95% CI; 1.01–1.10); those that received support for planning and organizing the work scheme (RR = 1.03, 95% CI; 1.01–1.05); those that monitored and analysed the goals set for each specialty offered at the DSC, with (RR = 1.06, 95% CI; 1.01–1.10) or without confirmatory documentation (RR = 1.06, 95%CI; 1.02–1.11); those whose team periodically performed self‐assessment processes, using the Ministry of Health's formal self‐assessment (AMAQ in Portuguese) (RR = 1.04, 95% CI; 1.02–1.05); those who followed clinical guidelines (with confirmatory documentation) regarding the referral of patients from primary care to the DSC (RR = 1.02, 95% CI; 1.01–1.04). On the contrary, DSCs that did not use the results achieved in previous PMAQ cycles in the organization of the DSC's team work scheme proved to be less likely to perform MS (RR = 0.98, 95% CI; 0.96–0.99). Conclusions Matrix support is associated with human resources and management factors in secondary oral health care in Brazil.
