Differences between surrogate telephone triage calls in an adult population and self calls.

We reviewed surrogate calls (i.e. those made on behalf of the patient) to a national triage call centre to determine whether there were differences between calls made by surrogates and self calls. During a three-year period there were 14,646 calls (14% of the total) made by a surrogate on behalf of the patient. Surrogate calls, as a percentage of total calls, increased with the age of the patient from 12% in the 18-34 year age group to 43% in the 80 and over age group (P < 0.0001). The symptoms of vomiting or nausea and dizziness or light-headedness were significantly more likely to be reported by surrogate callers than self callers. Surrogates reported a higher original intention of taking patients to the hospital emergency department (ED) compared with self callers across all adult age groups (OR 1.64; 95% CI 1.57 to 1.71). A higher proportion (38%) of surrogate calls ended with the nurse recommending an ED visit compared with only 26% of self calls (OR 1.72; 95% CI 1.66 to 1.79). Calls about men accounted for 54% of surrogate calls but only 26% of self calls (OR 3.3; 95% CI 3.2 to 3.4), suggesting that surrogate calls may be a way of increasing medical access for men.
