Implementation of a 24-Hour Teleradiology Service for Cruise Ships: A Pilot Study.

Abstract

OBJECTIVE. The purpose of this study was to introduce a 24-hour teleradiology service for cruise ships as a novel concept in maritime telemedicine. SUBJECTS AND METHODS. One cruise ship equipped with a mobile radiography unit and digital storage imaging plates was involved in this pilot study. Radiographs were transmitted via satellite internet to a tertiary hospital on shore for image interpretation by expert radiologists. Use of a virtual private network (VPN) enabled secure data transfer. Radiographs and patient data were automatically integrated into the PACS and radiology information system of the radiology department at the hospital. Images were analyzed by the staff radiologist at the hospital, and reports were immediately returned via e-mail through the VPN tunnel. RESULTS. Seventy-five radiographs of 47 patients were obtained on board within 2 months. All datasets were successfully transmitted. Most of the examinations (35 [≈ 75%]) were skeletal radiographs; the other 12 (≈ 25%) were chest radiographs. The turnaround time for the radiology reports was within 30 minutes in 43 cases (≈ 92%). In four cases (≈ 8%), delay was due to technical and organizational issues at the tertiary hospital. CONCLUSION. With the objective of supporting ship physicians with expert analyses of radiographs, a secure and stable method of image and radiology report transmission between an onboard hospital and a land-based radiology department was established.
