The effect of nuclear medicine telediagnosis on diagnostic pathways and management in rural and remote regions of Western Australia

Limited accessibility to certain medical imaging services in regional and rural centres has led to the use of alternative modalities, which may not be best practice or which require patients to travel considerable distances for diagnosis. Data collected over three years were examined to determine the clinical effect of nuclear medicine teleradiology (NMT) and its effect on diagnostic patterns for the investigation of cardiovascular disease, radio-occult musculoskeletal injury and oncology. In comparison with two other rural, non-NMT areas of similar demographic profile, there was a significant shift in the delivery of care in terms of diagnostic work-up. NMT input led to the detection of disease and a change to therapeutic management in 122 cases and eliminated the need to transfer patients to another facility for unnecessary and expensive examinations in 38 cases. While NMT is more costly than conventional nuclear medicine services, it permits faster access to specialist consultation, provides for better management and is likely to reduce overall health costs by reducing the volume of inappropriate tests and treatment practice.

Nuclear medicine teleradiology in regional and rural centres of Western Australia

We have established a nuclear medicine teleradiology service for rural and regional areas of south-west Western Australia. This study aimed to evaluate whether existing treatment models had altered in ways which were directly related to improved medical outcomes and reduced cost. Preliminary observation into musculoskeletal injury of the ankle joint included diagnosis of 10 radio-occult talar dome lesions which in some cases had not been identified until six months after the trauma. Several cases suggest that nuclear medicine provided a more timely diagnosis and actively altered treatment. Further, the potential role of radiologists as primary-care extenders in guiding appropriate investigations and defining the nature of the illness before specialist consultation may lessen the economic burden on public health care while creating economies of scale by expanding the clinical usefulness of the nuclear physician over a large rural area.
