Structure and work process in primary care and hospitalizations for sensitive conditions

Area of Science:

• Public Health
• Health Services Research
• Primary Care Management

Background:

• Primary care sensitive conditions (PCSC) are those amenable to prevention or treatment by timely and effective primary care.
• Understanding factors influencing PCSC hospitalizations is crucial for optimizing healthcare resource allocation and improving population health outcomes.
• The structure and work processes of primary health units (PHUs) are hypothesized to play a significant role in preventing unnecessary hospitalizations.

Purpose of the Study:

• To investigate the association between the structural characteristics of primary health units and the work processes of primary care teams.
• To determine the relationship between these primary care factors and the incidence of hospitalizations for primary care sensitive conditions in Brazilian municipalities.

Main Methods:

• An ecological study design was employed, analyzing data from Brazilian municipalities.
• Data included sociodemographic characteristics, care program coverage, PHU structure, and primary care team work processes.
• Negative binomial regression was used to estimate associations, with a hierarchical approach across three levels (distal, intermediate, proximal).

Main Results:

• Distal factors: Higher Human Development Index (HDI), older adult proportion, and Community Health Agent Strategy coverage were positively associated with PCSC hospitalizations. Bolsa Família Program and private insurance coverage showed negative associations.
• Intermediate factors: Minimum operational hours and vaccine availability were negatively associated with PCSC hospitalizations, while medication availability showed a positive association.
• Proximal factor: Matrix support within primary care teams showed a positive association with PCSC hospitalizations. Associations remained consistent between 2013 and 2014.

Conclusions:

• The structural characteristics of primary health units and the work processes of primary care teams demonstrably impact the rate of hospitalizations for primary care sensitive conditions.
• Specific elements, such as HDI, program coverage, operational hours, vaccine and medication availability, and matrix support, are key determinants influencing these hospitalization rates.
• These findings underscore the importance of strengthening primary care infrastructure and processes to reduce preventable hospitalizations.
