Abstract
Abstract Objectives: To evaluate the effect of proximity from subjects' residence to their clinic on the time to diagnostic resolution for subjects with a breast or cervical cancer screening abnormality in an urban safety net setting. Methods: Boston Patient Navigation Research Program collected data (2007- 2008) for women who had a breast or cervical cancer screening abnormality at six community health centers. Kaplan-Meier survival curves and proportional hazards regression models examined the effect of distance to clinic on time to resolution, adjusting for community health center, age, race, language, and insurance. Results: We geocoded addresses for 1512 of 1544 subjects (98%). Among those with a breast screening abnormality (36% Black, 33% Hispanic; 44% non-English), there was no significant difference in adjusted hazard ratios between the distance quartiles, 0.08 to >6.12 miles, (p-values 0.50-0.98). Among those with a cervical screening abnormality (22% Black, 21% Hispanic; 15% non-English) those in the closest distance quartile (<0.6 miles) were less likely to resolve than the next closest quartile (0.6-1.47 miles) (adjusted Hazard Ratio 0.756, 95% CI 0.574 -0.995). Cervical screening subjects living closest to their clinic were slower to resolve. Conclusions: Increased distance between residence and clinic is not a barrier to diagnostic resolution for this vulnerable urban population Citation Format: Ann M. Han, Tracy Battaglia, Veronica M.
