ObjectivesTo quantify dynamic availability of ambulatory care, and to examine possible associations with non-emergency treatments in emergency departments (EDs).MethodsLongitudinal data from the Taiwan National health Insurance Research Database were used to evaluate 749,584 emergency-medicine cases occurring between 2005 and 2010 according to a modified New York University algorithm. Multivariable-cumulative-logistic-regression analysis with generalized estimating-equation methods was used to determine associations between availability of ambulatory care and the urgency of patients' medical needs during ED visits.ResultsMore than half (53.04%) of the ED visits that were evaluated in our study were classified as non-emergencies, and over half of these occurred despite a high availability of ambulatory care facilities (median > 96%). Compared with patients in areas with a low availability of ambulatory care, patients in areas of medium to high availability showed approximately 0.8 times lower odds ratios for associations with non-emergency ED visits.ConclusionsNon-emergency ED visits may be reduced by increasing the availability of ambulatory care facilities in areas with deficits in the availability of such facilities. However, increasing the availability of ambulatory care by raising the number of available ambulatory care physicians or the number of ambulatory care facilities may not reduce non-emergency ED visits in areas with medium to high availability of ambulatory care facilities.Copyright © 2012 Elsevier Ireland Ltd.
