A Telemedicine Solution to Minimize Unnecessary Emergency Department Transfers for Low-acuity Pediatric Orthopaedic...

Unnecessary emergency department (ED) transfers represent a notable source of excess costs and misutilization of healthcare resources, particularly with management of acute pediatric musculoskeletal injuries. This study used institutional data to create a model investigating the expected costs of a formal peer-to-peer telemedicine intervention designed to triage pediatric orthopaedic transfers, which we hypothesized would decrease healthcare costs by minimizing unwarranted ED-to-ED transfers.

In this retrospective modeling analysis, 350 pediatric orthopaedic trauma patients transferred to two in-network referral hospitals from outside facilities were identified and stratified into three groups representing how patients theoretically optimally could have been treated. Group 1 patients required ambulance transfer, group 2 patients required ED-level care but no ambulance transfer, and group 3 patients did not require ED-level care. Base case estimates for the proportions of patients in each group, probability of ambulance transport, and direct costs of care for each patient were derived from the database. A decision tree was developed to evaluate the expected costs of two triaging strategies: (1) transfer everyone or (2) triage first using e-consultation. Probabilistic sensitivity analyses were used to determine how the results of the decision analysis varied across ranges of cost and probability estimates.

In the base case analysis, the telemedicine triage strategy was cheaper than the transfer-all strategy ($4,858 versus $6,610). In a 2-way sensitivity analysis comparing cost of a telemedicine visit and proportion of telemedicine triaged patients requiring ambulance transport, the telemedicine triage strategy remained cheaper than the transfer-all strategy across almost all possibilities for both variables. Additional potential benefits of triage before transfer, such as decreased length of time to completion of ED visit, cost to the family, and patient comfort and satisfaction, were not incorporated into this analysis. The potential for misdiagnosis related to telehealth and its potential costs were not included.

We revealed substantial cost savings for the healthcare system from implementing a telehealth platform for peer-to-peer consultation when considering patient transfer for musculoskeletal trauma. Initial peer-to-peer e-consultations cost less than reflexive ambulance transfer in most situations.
