Although it is well known that a successful implementation depends on the front-liners’ knowledge and participation, as well as on the organizational capacity of the institutions involved, we still know little about how front-line health workers have been involved in the implementation of the Brazilian National Program for Improving Access and Quality to Primary Care (PMAQ). This paper develops a contingent mixed-method approach to explore the perceptions of front-line health workers - managers, nurses, community health workers, and doctors - regarding the PMAQ (2nd round), and their evaluations concerning health unit organizational capacity. The research is guided by three relevant inter-related concepts from implementation theory: policy knowledge, participation, and organizational capacity. One hundred and twenty-seven health workers from 12 primary health care units in Goiânia, Goiás State, Brazil, answered semi-structured questionnaires, seeking to collect data on reasons for adherence, forms of participation, perceived impact (open-ended questions), and evaluation of organizational capacity (score between 0-10). Content analyses of qualitative data enabled us to categorize the variables “level of perceived impact of PMAQ” and “reasons for adhering to PMAQ”. The calculation and aggregation of the means for the scores given for organizational capacity enabled us to classify distinct levels of organizational capacity. We finally integrated both variables (Perceived-Impact and Organizational-Capacity) through cross-tabulation and the narrative. Results show that nurses are the main type of professional participating. The low organizational capacity and little policy knowledge affected workers participation in and their perceptions of the PMAQ.

PurposeThis paper employs implementation theory and the political literature on performance measurement to understand how frontline health workers know, participate and evaluate the Brazilian National Program for Improving Access and Quality of Primary Care (PMAQ, 2nd round).Design/methodology/approachThis paper develops an implementation theory-driven qualitative analysis. The research is developed in the city of Goiania (Brazil): a challenging organizational context in primary care (PHC). Interviews were carried out with 25 frontliners – managers, doctors, nurses and community health workers. Data were thematically and hierarchically analysed according to theoretical concepts such as policy knowledge, policy adherence, forms of accountability, alternative logics, organizational capacity and policy feedback.FindingsResults show the need to foster organizational capacity, knowledge, participation and policy feedback at the frontline. Successful implementation would require those adaptations to counteract policy challenges/failures or the emergence of alternative logics.Research limitations/implicationsThe study was conducted in only one setting, however, our sample includes different types of professionals working in units with different levels of organization capacity, located in distinct HDs, expressing well the implementation of PMAQ/P4P. Qualitative researches need to be developed for further exploring the same/other factors.Social implicationsFindings can be used to improve discussions/planning and design of P4P programs in the city and State of Goias.Originality/valueThe majority of analysis of PMAQ are of a quantitative or results-based nature. This article focuses on politically significant and unanswered questions regarding the implementation of PMAQ.
