Background:
Preventive service delivery, including cancer screenings, continues to pose a challenge to quality improvement efforts. Although many studies have focused on person-level characteristics associated with screening, less is known about organizational influences on cancer screening.
Objectives:
This study aims to understand the association between organizational factors and adherence to cancer screenings.
Methods:
This study employed a cross-sectional design using organizational-level, patient-level, and area-level data. Dependent variables included breast, cervical, and colorectal cancer screening. Organizational factors describing resource sufficiency were constructed using factor analyses from a survey of 250 Veterans Affairs primary care directors. We conducted random-effects logistic regression analyses, modeling cancer screening as a function of organizational factors, controlling for patient-level and area-level factors.
Results:
Overall, 87% of the patients received mammograms, 92% received cervical and 78% had colorectal screening. Quality improvement orientation increased the odds of cervical [odds ratio (OR): 1.27; 95% confidence interval (CI), 1.03-1.57] and colorectal cancer screening (OR: 1.10; 95% CI, 1.00-1.20). Authority in determining primary care components increased the odds of mammography screening (OR: 1.23; 95% CI, 1.03-1.51). Sufficiency in clinical staffing increased the odds of mammography and cervical cancer screenings. Several patient-level factors, serving as control variables, were associated with achievement of screenings.
Conclusions:
Resource sufficiency led to increased odds of screening possibly because they promote excellence in patient care by conveying organizational goals and facilitate goal achievement with resources. Complementary to patient-level factors, our findings identified organizational processes associated with better performance, which offer concrete strategies in which facilities can evaluate their capabilities to implement best practices to foster and sustain a culture of quality care.
