BackgroundMillions of interventional pain procedures are performed each year to address chronic pain. The increase in these procedures also raises the concern of health risks associated with ionizing radiation for interventional pain management physicians who perform fluoroscopy-guided operations. Some health concerns include cancers, cataracts, and even pregnancy abnormalities. Little is known regarding the long-term and cumulative effects of small radiation doses.ObjectivesThe objective of this systematic review was to identify common body parts that are exposed to ionizing radiation during interventional pain procedures and examine methods to help physicians reduce their radiation exposure.Study DesignThe Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) checklist was used to comprehensively identify articles from 2 medical databases. The radiation dose to interventional pain management physicians obtained from relevant peer-reviewed articles were aggregated and used for analysis.MethodsPubMed was first used to collect the articles for two broad keyword searches of "radiation exposure pain management" and "radiation exposure interventionalist" with years ranging from 1956 - February 2023. EMBASE was also used to collect the articles for the two keyword searches of "radiation exposure pain management" and "radiation exposure interventionalist" with years ranging from 1969 - February 2023. This systematic approach yielded a total of 2,736 articles; 24 were included in our paper. The risk of bias for these articles was performed using the Cochrane Risk of Bias tool and the National Institutes of Health tool.ResultsThrough our systematic literature search, more than 3,577 patients were treated by 30 interventional pain management physicians. Some areas of exposure to radiation include the physician's neck, chest, groin, hands, and eyes. One common body region that is exposed to radiation is the chest; our review found that wearing lead aprons can lower the radiation dose by more than 95%. Wearing protective equipment and managing the distance between the operator and fluoroscope can both independently lower the radiation dose by more than 90% as well. Our literature review also found that other body parts that are often overlooked in regard to radiation exposure are the eyes and hands. In our study, the radiation dose to the outside (unprotected) chest ranged from 0.008 ± 27 mrem to 1,345 mrem, the outside neck ranged from 572 mrem to 2,032 mrem, the outside groin ranged from 176 mrem to 1,292 mrem, the hands ranged from 0.006 ± 27.4 mrem to 0.114 ± 269 mrem, and the eyes ranged from 40 mrem to 369 mrem. When protective equipment was worn, the radiation exposure to the inside chest ranged from 0 mrem to 108 mrem, the inside neck ranged from 0 mrem to 68 mrem, and the inside groin ranged from 0 mrem to 15 mrem.LimitationsLimitations of this study include its small sample size; only the radiation exposure of 30 interventional pain management physicians were examined. Furthermore, this review mainly consisted of observational studies rather than randomized clinical trials.Conclusion  Implementing safety precautions, such as wearing protective gear, providing educational programs, and keeping a safe distance, demonstrated a significant decrease in radiation exposure. The experience of interventional pain management physicians also factored into their radiation exposure during procedures. Radiation is a known carcinogen, and more research is needed to better understand its risk to interventional pain management physicians.
