Distance Traveled by Patients Globally to Access Radiotherapy: A Systematic Review
Abstract
PURPOSE/OBJECTIVE(S)
This systematic review aims to investigate the global travel patterns of patients seeking radiotherapy and examines the distance traveled by patients and its impact on secondary outcomes such as travel time and survival. The findings of this review will provide crucial information on barriers to accessing radiotherapy and inform the development of patient-centered care strategies aimed at improving access to this important form of treatment.
MATERIALS/METHODS
A comprehensive search of four databases was conducted from June to August 2022. Studies were included if they were observational, retrospective, or randomized/non-randomized, published between June 2000 and June 2022, and reported the distance traveled globally for the treatment of malignant or benign disease. Studies were excluded if they did not report travel distance or were not written in English.
RESULTS
A total of 176 studies were included. Most of the studies (69.9%) were conducted in North America, with the majority (68.7%) in the United States. The treatment modalities varied with external beam radiation therapy being the most common (17.0%). The most common disease site was breast (26.7%). Of the included studies, 49 reported the mean distance traveled for radiation therapy. The shortest mean distance was reported in the United States at 4.83 miles, while the longest was reported in Iran at 276.5 miles. It was observed that patients living in countries outside the United States traveled…
How strong is the evidence?
Evidence Hub reads this as a systematic review, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid.
