Variation in radiation dosing among pediatric trauma patients undergoing head computed tomography scan.

BACKGROUND: When head injured children undergo head computed tomography (CT), radiation dosing can vary considerably between institutions, potentially exposing children to excess radiation, increasing risk for malignancies later in life. We compared radiation delivery from head CTs at a level 1 pediatric trauma center (PTC) versus scans performed at referring adult general hospitals (AGHs). We hypothesized that children at our PTC receive a significantly lower radiation dose than children who underwent CT at AGHs for similar injury profiles. METHODS: We retrospectively reviewed the charts of all patients younger than 18 years who underwent CT for head injury at our PTC or at an AGH before transfer between January 1 and December 31, 2019. We analyzed demographic and clinical data. Our primary outcome was head CT radiation dose, as calculated by volumetric CT dose index (CTDIvol) and dose-length product (DLP; the product of CTDIvol and scan length). We used unadjusted bivariate and multivariable linear regression (adjusting for age, weight, sex) to compare doses between Children's Hospital Los Angeles and AGHs. RESULTS: Of 429 scans reviewed, 193 were performed at our PTC, while 236 were performed at AGHs. Mean radiation dose administered was significantly lower at our PTC compared with AGHs (CTDIvol 20.3/DLP 408.7 vs. CTDIvol 30.6/DLP 533, p < 0.0001). This was true whether the AGH was a trauma center or not. After adjusting for covariates, findings were similar for both CTDIvol and DLP. Patients who underwent initial CT at an AGH and then underwent a second CT at our PTC received less radiation for the second CT (CTDIvol 25.6 vs. 36.5, p < 0.0001). CONCLUSIONS: Head-injured children consistently receive a lower radiation dose when undergoing initial head CT at a PTC compared with AGHs. This provides a basis for programs aimed at establishing protocols to deliver only as much radiation as necessary to children undergoing head CT. LEVEL OF EVIDENCE: Care Management/Therapeutic, level IV.

Moving Toward Standardized Pediatric Performance Improvement Measures in Child Physical Abuse: A Modified Delphi Approach.

BACKGROUND: Limited guidance exists for pediatric trauma centers (PTCs) regarding best practice for measuring and reviewing performance improvement (PI) in the child physical abuse population. To move PTC programs toward standardized guidelines and PI practices, current practice and points of consensus among level 1 and 2 PTCs across the United States were assessed. METHODS: Utilizing a two-round, modified Delphi methodology, electronic surveys were distributed to pediatric trauma program managers and coordinators representing 125 PTCs. Survey data included demographics, coding practices, definitions, current PI measures, prevention programs, and opinions regarding key components of child physical abuse guidelines. RESULTS: In Round 1, responses were received from 90 (72%) PTCs [47 (84%) ACS-verified level 1 PTCs; 29 (73%) ACS-verified level 2 PTCs; and 14 (48%) state PTCs]. Of the respondents, 87% agreed that establishing a national consensus for child physical abuse PI is important, and 92% agreed that their institution would benefit from standardized guidelines. Although PI process varied among PTCs in terms of measures, review, and coding practices, several points of consensus were achieved. CONCLUSION: Survey results demonstrate areas of consistency and a foundation for consensus among PTCs. Results also identify areas of practice diversity that may benefit from an attempt to standardize PI across centers.
