How do teleconsultations for remote trauma management change over a period of time?

We obtained follow-up information about the new patients seen at a minor accident and treatment service (MATS) staffed by emergency nurse practitioners (ENPs). A previous study, of 150 teleconsultations in a six-month period starting in April 1996, was used for comparison. In the present series, 150 teleconsultations occurring in a four-month period starting in April 1999 were studied; the patients constituted 5.6% of the 2658 new attenders or 3.8% of the 3936 total attenders. In comparison with the study three years before, falling teleconsultation rates were partly offset by increasing numbers of attenders and an extension of the ENPs' roles and skills. Teleconsultation rates rose when the number of consultant-run clinics was curtailed and ENP-run clinics replaced some of them. Eligibility to request and report more radiographs reduced the need for teleconsultations, and subsequently teleconsultations for help with interpretation of radiographs fell as the ENPs became more experienced. Specialty residents trusted ENP judgement and accepted telephoned direct admission of cases to their wards. Fewer teleconsultations were required for soft-tissue injuries. Telemedicine is an excellent educational tool.
