One page on PainSci cites Schepens 2023: Science round-up: six painful science stories from 2023

PainSci commentary on Schepens 2023: ?This page is one of thousands in the bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided wherever possible.

Schepens et al. reported on poor outcomes from thousands of Dutch lumbar disk herniation surgeries, with straightforward and ugly results: almost a quarter (23%) had “one or more undesirable outcomes,” with many people getting a second surgery, a nerve blocks, and/or taking opioids to cope after their failed treatment.

That’s really a lot of poor outcomes. In fact, I think you'd be hard-pressed to find an elective surgery with worse stats.

STUDY DESIGN: Retrospective cohort study.

OBJECTIVE: There is only limited data on the outcome of primary surgery of lumbar disk herniation (LDH) in Dutch patients. The objective of this study is to describe undesirable outcomes after primary LDH.

METHODS: The National Claims Database (Vektis) was searched for primary LDH operations performed from July 2015 until June 2016, for reoperations within 18 months, prescription of opioids between 6 to 12 months and nerve root block within 1 year. A combined outcome measure was also made. Group comparisons were analyzed with the Student's t-test.

RESULTS: Primary LDH surgery was performed in 6895 patients in 70 hospitals. Weighted mean of reoperations was 7.3%, nerve root block 6.7% and opioid use 15.6%. In total, 23.0% of patients had one or more undesirable outcomes after surgery. The 95% CI interval exceeded the 50% incidence line for 14 out of 26 hospitals with less than 50 surgical interventions per year. Although the data suggested a volume effect on undesired outcomes, the t-tests between hospitals with volume thresholds of 100, 150 and 200 interventions per year did not support this (P values 0.078, 0.129, 0.114).

CONCLUSION: This unique nationwide claims-based study provides insight into patient-relevant undesirable outcomes such as reoperation, nerve root block and opioid use after LDH surgery. About a quarter of the patients had a serious complication in the first follow up year that prompted further medical treatment. There is a wide variation in complication rates between hospitals with a trend that supports concentration of LDH care.
