Among the general population, having a regular FP was associated with having better access to FPs for immediate care (P<.001) but was not associated with a decreased likelihood of ED visits (odds ratio [OR] = 1.49, P = .03). Better actual access to FP services for immediate care was associated with a decreased likelihood of ED use (OR = 0.62, P<.001) among the general population. Among those with chronic diseases, having a regular FP was associated with a decreased likelihood of ED use (OR = 0.47, P = .01)
