Abstract

Abstract : Objectives: Patients ≥65 years old represent 30%–50% of all ambulance assignments (AAs), and the knowledge of which care level they are disposed to is limited and diverging. The aim of this study was therefore to describe and compare characteristics of patients' aged ≥65 years dispositions during AA, including determining changes over time and factors associated with non-conveyance to hospitals. Design: A longitudinal and comparative database study. Setting: Ambulance service in a Swedish region. Participants: 32 085 AAs with patients ≥65 years old during the years 2014, 2016 and 2018. Exclusion criteria: AAs with interhospital patient transfers and lack of patients' dispositions data. Outcome measures: Dependent factors: conveyance and non-conveyance to hospitals. Independent factors: age, sex, symptom, triage level, scene, time, day and season. Results: The majority (n=29 060; 90.6%) of patients' dispositions during AA were conveyance to hospitals. In total, the most common symptoms were circulatory (n=4953; 15.5%) and respiratory (n=4529; 14.1%). A significant increase, p<0.01, of non-conveyance to hospitals was shown during 2014 and 2018, from 801 (7.8%) to 1295 (11.4%). Increasing age was associated with decreasing odds of non-conveyance, 85–89 years (OR=0.85, 95 % CI=0.72 to 0.99) and 90 years or older (OR=0.80, 95 % CI=0.68 to 0.93). Several factors were associated with non-conveyance, for example, symptoms of diabetes (OR=8.57, 95 % CI=5.99 to 12.26) and mental disorders (OR=5.71, 95 % CI=3.85 to 8.48) in comparison with infections. Conclusions: The study demonstrates several patient characteristics, and factors associated with non-conveyance to hospitals, such as age, symptom, triage level, scene, time, day and season. The increasing non-conveyance trend highlights the importance of further studies on optimal care levels for patients ≥65 years old.
