Malpractice claims in spine surgery in Germany: a 5-year analysis.

STUDY DESIGN: Retrospective analysis of anonymized malpractice claims.

SUMMARY OF BACKGROUND DATA: Spine surgery is considered a high-risk specialty with regards to malpractice claims. However, limited data is available for Germany. We analyzed the rate, subject and legal outcome of malpractice claims faced by spine surgeons in one of the largest Medical Council coverage areas in Germany, representing 60,000 physicians and a population of 10 million.

METHODS: Analysis of all malpractice claims regarding spinal surgeries completed by the Review Board (RB) of the North Rhine Medical Council (NRMC) from 2012-2016. Claim merit, content and actual treatment errors were reviewed. Severity of damage was graded from negligible (1) to death (6).

RESULTS: A total of 8,381 malpractice cases were reviewed by the NRMC from 2012-2016. Four percent (340 cases: 181 females, 159 males) pertained to patients undergoing spinal surgery with 94.7% of patients undergoing in-hospital treatment and 5.3% as outpatients. Malpractice claims most frequently involved neurosurgery (48.5%) and orthopedic surgery (37.6%). Trauma surgery was involved in 9.1% and other specialties in 4.8%. Actual treatment errors were found in 89 of 340 cases (26.2%).Of those, 81 resulted in treatment-associated health impairment. Negligible and/or temporary impairment was found in 49.3%. Negligible to moderate but permanent damage was observed in 39.5%. Nine patients suffered severe permanent damage or death (11.1%). The treated diagnosis was degenerative disc disease in 34 patients (41.9%), spinal canal stenosis in 13 (16%), vertebral body fractures in 10 (12.3%), spondylolisthesis in 6 (7.4%), and other diagnoses accounting for the remaining 18 (22.2%). Errors involved actual surgical treatment in 40.7%, surgical indication and pre-operative workup in 28.4%, postoperative treatment in 25.9%, and patient consent in 4.9%.

CONCLUSION: Spinal surgery claims account for 4% of all claims reviewed by the NRMC in the 5-year period from 2012 to 2016. Eighty-nine (26.2%) were deemed justified. The majority of treatment errors (59.3%) occurred during workup, indication and consent, or during postoperative care. Errors during actual surgery were responsible for 40.7% of all treatment-associated damages. Understanding the distribution and content of claims is key to improving patient satisfaction not only by honing surgical skills, but also by improving pre- and post-operative communication and care.
