Abstract
Purpose: The purpose of this study was to examine associations between the number and types of patients' chronic diseases and being up to date for breast, cervical, and colorectal cancer screening.
Methods: Data were abstracted from medical charts at 4 primary care clinics located in 2 rural Oregon communities. Eligibility criteria included being at least 55 years old and having at least 1 clinic visit in the past 2 years.
Results: Of 3433 patients included, 503 (15%) had no chronic illness, 646 (19%) had 1, 786 (23%) had 2, and 1498 (44%) had ≥3 chronic conditions. Women with asthma/chronic lung disease and with cardiovascular disease were less likely to be up o date for mammography screening (odds ratio [OR], 0.59; 95% confidence interval [CI], 0.43–0.80), and those with chronic digestive disorders were more likely to be up to date for mammography (OR, 1.31; 95% CI, 1.03–1.66) compared with those without chronic conditions. Women with arthritis, diabetes mellitus, and hypertension were less likely to be up to date for cervical cancer screening (OR, 0.38; 95% CI, 0.21–0.68) compared with those without chronic conditions. Men with cardiovascular disease were less likely to be up to date for colorectal cancer screening (adjusted OR, 0.59; 95% CI, 0.44–0.80), and women with depression were less likely to be up to date (OR, 0.71; 95% CI, 0.56–0.91) compared with men and women without chronic conditions.
Conclusion: Specific chronic conditions were found to be associated with up-to-date status for cancer screening. This finding may help practices to identify patients who need to receive cancer screening.
