EMS and many OOH-PC use telephone triage, yet the patient still makes the initial choice of contacting a service and which service. Sociodemographic characteristics are associated with help-seeking. Yet, differences in characteristics for EMS and OOH-PC patients have not been investigated in any large-scale cohort studies. Such knowledge may contribute to organizing OOH services to match patient needs. Thus, in this study we aimed to explore which sociodemographic patient characteristics were associated with utilizing OOH health care and to explore which sociodemographic characteristics were associated with EMS or OOH-PC contact.Methods: A population-based observational cohort study of inhabitants in two regions (North Denmark Region and Capital Region of Copenhagen) with or without contact to OOH services during 2016 was conducted. Associations between sociodemographic characteristics and OOH contacts (and EMS versus OOH-PC contact) were evaluated by regression analyses.Results: We identified 619,857 patients with OOH contact. Female sex (IRR=1.16 (95% CI: 1.16– 1.17)), non-western ethnicity (IRR=1.02 (95% CI: 1.01– 1.02)), living alone (IRR=1.08 (95% CI: 1.08– 1.09)), age groups ≥ 81 years (IRR=2.00 (95% CI: 1.98– 2.02)) and 0– 18 years (IRR=1.66 (95% CI: 1.66– 1.67)) and low income (IRR=1.41 (95% CI: 1.40– 1.42)) were more likely to contact OOH health care compared to males, Danish ethnicity, citizens cohabitating, age 31– 65 years and high income. Disability pensioners more often contacted OOH care (IRR=1.79 (95% CI: 1.77– 1.81) compared to employees. Old age (≥ 81 years) (OR=3.21 (95% CI: 3.13– 3.30)), receiving cash benefits (OR=2.45 (95% CI: 2.36– 2.54)), low income (OR=1.76 (95% CI: 1.72– 1.81)) and living alone (OR=1.40 (95% CI: 1.37– 1.42)) were all associated with EMS contacts rather than OOH-PC contacts.Conclusion: Several sociodemographic factors were associated with contacting a health care service outside office hours and with contacting EMS rather than OOH-PC. Old age, low income, low education and low socioeconomic status were of greatest importance.Keywords: out-of-hours health care, delivery of health care, Denmark, telephone hotline, telephone triage
