The value of telephone triage for patients with appendicitis

Although it has been assumed that telephone triage can directly benefit patients by facilitating early diagnosis and treatment, this potential benefit has not been well documented. Using appendicitis cases ascertained from claims data, we compared telephone triage recommendations with what the callers originally intended to do. Over a two-year period, there were 20,230 calls to a telephone triage centre in the US where insurance information was available. Of these, 12,709 calls (63%) had insurance claims made within seven days of the call. Among these calls, 46 had a diagnosis of appendicitis. In 72% of calls concerning appendicitis, the telephone triage recommendation was for a more rapid evaluation than the caller originally intended (P < 0.0001). In 91% of the appendicitis cases, triage nurses directed callers to care within 8 h, but without triage advice, only 39% of callers stated they would have sought care within 8 h (P < 0.0001). Telephone triage significantly reduced the delay in care for appendicitis in comparison with what the caller would have done. This suggests that telephone triage potentially reduces the morbidity associated with appendicitis.
