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.

Purpose This study aimed to describe extended collaboration in situations when an ambulance was called, as experienced by older patients, a significant other, and ambulance- and primary healthcare (PHC) centre personnel. Methods The study used a phenomenological reflective lifeworld research (RLR) approach. Participants included in three specific situations with extended collaboration were interviewed: three older patients, one significant other, three ambulance personnel and four personnel at the PHC centre. The transcribed interviews were analysed for meanings of the phenomenon. Results The extended collaboration means that decisions were supported through dialogue by bridging knowledge spaces between person, within-team and across-team levels. Through dialogue experience and knowledge were shared and certainty in decisions was increased. The extended collaboration was built on trust, responsibility taken, shared and entrusted, and the common goal of adapted care for the unique patient. A need for further improvement and transparency was elucidated. Conclusions The difficulty of making care decisions stresses the importance of available extended collaboration based on the dialogue between patients, significant others, and ambulance- and PHC centre personnel to increase certainty in decisions. Collaboration further requires respectful encounters, trust, responsibility and a common goal of adapting the care for the unique patient.
