Background Although there is a low incidence of complications associated with epidural injections, pain physicians should still remain vigilant for potentially serious adverse outcomes. This study aimed to identify and describe the major complications of epidural injections.
Methods This retrospective, observational, medicolegal study analyzed closed cases of precedents involving complications of epidural injections from January 1997 to August 2019 using the database of the Supreme Court of Korea’s judgement system. Clinical characteristics and judgement statuses were analyzed.
Results Of the 73 potential cases assessed for eligibility, a total of 49 malpractice cases were included in the final analysis. Thirty-three claims resulted in payments to the plaintiffs, with a median payment of US$103 828 (IQR: US$45 291–US$265 341). The most common complication was infection (n=13, 26.5%), followed by worsening pain (n=8, 16.3%). Physician malpractice before, during, and after the procedure was claimed by plaintiffs in 18 (36.7%), 44 (89.8%), and 31 (63.3%) cases, respectively. Of these cases, 6 (33.3%), 19 (43.2%), and 15 (48.4%), respectively, were adjudicated in favor of the plaintiffs by the courts. In cases involving postprocedural physician errors, the majority (13/15) of the plaintiff verdicts were related to delayed management. Violation of the physician’s duty of informed consent was claimed by plaintiffs in 31 (63.3%) cases, and 14 (45.2%) of these cases were judged medical malpractice.
Conclusions Our data will allow pain physicians to become acquainted with the major epidural injection-associated complications that underlie malpractice cases.
- chronic pain
- epidural injection
- legislation and jurisprudence
