Association between travel distance and face-to-face consultations with general practitioners before an incident acute myocardial infarction: a nationwide register-based spatial epidemiological study

Abstract

ObjectivesThis study examined the association between travel distance to the general practitioner’s (GP) office andnoface-to-face GP consultation within 1 year before an incident acute myocardial infarction (AMI).DesignA prospective cohort study using multilevel spatial logistic regression analysis of nationwide register data.SettingNationwide study including contacts to GPs in Denmark prior to an incident AMI in 2005–2017.Participants121 232 adults (≥30 years) with incident AMI were included in the study.Primary and secondary outcomes measuresThe primary outcome was odds of not having a face-to-face GP consultation within 1 year before an incident AMI.ResultsIn total, 13 108 (10.8%) of the 121 232 individuals with incident AMI had no face-to-face consultation with the GP within 1 year before the AMI. Population density modified the association between travel distance andnoface-to-face GP consultation. Increased odds ofnoface-to-face GP consultation was observed for medium (25th–75th percentile/1123–5449 m) and long (>75th percentile/5449 m) compared with short travel distance (<25th percentile/1123 m) among individuals living in small cities (OR (95% credible intervals) of 1.19 (1.10 to 1.29) and 1.19 (1.06 to 1.33), respectively) and rural areas (1.46 (1.26 to 1.68) and 1.48 (1.29 to 1.68), respectively). No association was observed for individuals living in large cities and the capital.ConclusionsTravel distance above approximately 1 km was significantly associated withnoface-to-face GP consultation before an incident AMI among individuals living in small cities and rural areas. The structure of the healthcare system should consider the importance of geographical distance between citizens and the GP in remote areas.
