Frequent contacts to Emergency Medical Services (EMS): more than frequent callers.

Background: A frequent caller is defined by The Frequent Caller National Network (FreCaNN) as an adult who makes five or more emergency calls in a month or twelve or more in three months, related to individual episodes of care. However, we believe that when limiting the definition to those who call themselves, one underestimates the impact frequent contacts have on the Emergency Medical Communication Center (EMCC) and the Emergency Medical Services (EMS).

Method: We conducted a descriptive retrospective cross-sectional database review of frequent contacts; defined as persons who have ≥ 5 contacts in a month or ≥ 12 contacts in three months. Data were provided from Oslo EMCC, between 1. January 2017 and 31. December 2022. Contrary to the FreCaNN definition, we included all types of contacts and callers, both emergent and non-emergent, regarding patients of all ages.

Results: During the study period, 2.149.400 contacts were registered. Of these 129.700 were contacts from frequent callers, where the patients called themselves. When including contacts frequently made on behalf of a patient, we found that 268.723 fit the definition of frequent emergency contacts. When also taking non-emergent contacts into account, a total of 437.361 contacts fit the definition of frequent contacts.

Conclusion: When limiting the criteria to only frequent callers, one underestimates the impact persons who have frequent contacts, have on the EMCC and the EMS. We were able to distinguish between three categories-contacts from frequent callers, frequent emergency contacts, and frequent contacts. We believe broadening the definition can benefit both research and audits, when accessing the use of emergency resources to patients with frequent requests for help to the EMCCs.
