Availability of Common Pediatric Radiology Studies: Are Rural Patients at a Disadvantage?

BACKGROUND: Many families wish to have radiologic tests performed locally, especially when obtaining these tests in specialized pediatric centers would require long-distance travel with associated costs and inconveniences. The differential availability of specialized and common pediatric uroradiographic tests in rural and urban areas has not been described. We undertook this study to describe the availability of common radiographic tests ordered by pediatric urologists, and to identify disparities in the availability of radiographic tests between urban and rural locations.

MATERIALS AND METHODS: We surveyed all freestanding hospitals in Washington State on the availability of flat-plate abdominal radiograph (AXR), renal-bladder ultrasounds (RBUS), voiding cystourethrograms (VCUG), MAG-3 renal scans, and nuclear cystograms (NC) for children, as well as testing restrictions, availability of sedation for urology tests, and presence of onsite radiologists. Rural and urban hospitals were compared on these characteristics.

RESULTS: The survey was completed by 74 of 88 institutions (84.1%); 17 (23.0%) were rural (population <2500), 32 (43.2%) were in urban clusters (population 2500-50,000), and 25 (33.8%) were in urban areas (population >50,000). Seventy-three (98.6%) institutions offered AXR, 68 (91.9%) offered RBUS, 44 (59.5%) offered VCUG, 26 (35.1%) offered MAG-3, and 15 (20.3%) offered NC to children. All urban and most (16/17; 94.1%) rural institutions had shareable digital imaging capability. AXR (100% versus 96%, P = 0.88) and RBUS (70.6% versus 96%, P = 0.15) availability was similar in rural and urban settings, whereas VCUG (11.8% versus 72%, P = 0.001), MAG-3 (5.9% versus 60%, P = 0.006), and NC (0% versus 44%, P = 0.017) were more commonly available in urban settings. Fewer rural hospitals employed full-time, in-house radiologists (35.3% versus 96%, P < 0.0001) or offered sedation (6.3% versus 36%, P = 0.01) for testing, but an equal proportion had age restrictions on the tests offered (40% versus 17.6%, P = 0.50). Fellowship-trained pediatric radiologists (0% versus 16%, P = 0.39) and child life specialists (0% versus 20%, P = 0.28) worked exclusively in urban settings. Most hospitals offering specialized radiographic tests (VCUG: 90.9%; P < 0.0001 and MAG-3: 92.3%; P = 0.002) had onsite radiologists.

CONCLUSIONS: The geographically widespread availability of AXR and RBUS may represent an opportunity to offer families care closer to home, realizing cost and time savings. Anxious children and those requiring more specialized studies may benefit from referral to urban centers. The lack of rural radiologists may be an actionable barrier to availability of specialized radiology testing.
