Background: No definitive solution has been forthcoming for the often dangerously long interval between symptom onset and seeking medical care in the prehospital setting. We examined the implementation of telemedicine technology and characterization of its utilizers for its efficacy in reducing this possibly life-threatening time lag.
Materials and methods: A retrospective observational study was performed on the working database of an operational telemedicine facility that included all subscribers. Time-to-contact measurements throughout 2012 were retrieved from its medical files, and data on age, gender, medical history, and main complaint were analyzed.
Results: Throughout 2012, 22,274 of a total of 46,556 calls (47.8%) were made ≤60 min from symptom onset. It is important that 26.9% of all calls (12,522/46,556) were made in <15 min. Significantly more males (10,794/22,229 [49%]) contacted in ≤60 min compared with females (11,480/24,327 [47%], p<0.03). Subjects <60 years of age (2,889/5,717 [51%]) called earlier than those >60 years (19,386/40,839 [47%], p<0.001). Patients with prior resuscitation and/or myocardial infarction contacted significantly more rapidly than those with other cardiac diseases. Over one-half of patients with cardiac complaints contacted the call center ≤60 min from symptom onset, as did those who suffered physical trauma, but not patients with gastrointestinal symptoms or pain elsewhere.
Conclusions: A telemedicine system with rapid accessibility to a professional call center and prompt triage thereafter could be an additional promising strategy for shortening the interval between symptom onset and call for medical assistance. Implementation of a widespread telemedicine infrastructure may bridge the unmet gap between occurrence of symptoms to initiation of medical treatment.
