A decade’s experience in lumbar spine surgery in Belgium: sickness fund beneficiaries, 2000–2009

Abstract

Purpose The purpose is to study rates, trends, geographic variations and outcome of lumbar spine surgery in the Belgian population during the last decade. Methods This is a retrospective cohort study using administrative data of the largest Belgian sickness fund from January 1, 2000 through December 31, 2009. Cases included lumbar laminectomy, combined discectomy and fusion, posterior interarticular fusion, anterior lumbar interbody fusion (ALIF), posterior lumbar interbody fusion (PLIF) and standard discectomy. The main outcome measures were age-and sex-adjusted rates of lumbar spine surgery, 1-year mortality, 1-year iterative surgery, no return to work (RTW) rate 1 year after surgery and length of hospital stay. Multivariate logistic regression analysis was used to determine the association between age, sex, geographic region, type of surgery, year of intervention and duration of pre-operative sick leave on outcome. Results Spine surgery rates rose 44 % from 2001 through 2009 and data for 2009 showed twofold variations in spine surgery rates among 10 Belgian provinces. Reported 1-year mortality varied from 0.6 to 2.5 % among surgical procedures performed in 2008. The overall 5-year reoperation rate was 12 %. RTW rates 1 year after standard discectomy, ALIF, PLIF and combined discectomy and fusion for the follow-up sample of 2008 were 14.4, 22.7, 26.1 and 30.6 %, respectively. The median length of hospital stay significantly decreased throughout the decade. Type of surgery and geographic region were significantly related to patient outcomes. Conclusions Regional variations highlight professional uncertainty and controversy. The study results point to the need for peer comparisons and surgeon feedback.

Body Mass Index and Risk for Clinical Lumbar Spinal Stenosis

“…We have also observed a similar trend in Europe, where LSS has become the most common indication for spine surgery in many European countries. [20][21][22][23] Increasing age in the population, increased use of magnetic resonance imaging, and systematic differences in health care are major factors to account for this trend, although the impact of biological factors might also be of importance. 13 , 17 , 20 , 24-27 With the current increased rate in LSS, the global rates of overweight and obesity have concomitantly increased dramatically since 1980.…”

Comparison of 368 Patients Undergoing Surgery for Lumbar Degenerative Spondylolisthesis From the SPORT Trial With 955 From the NSQIP Database

“…[3][4][5][6][7][8][9][10][11] It holds a distinguished position in the spine literature as a randomized surgical trial, and this unique and highly valued study design has attracted much attention.

Return to work after spinal stenosis surgery and the patient’s quality of life

“…According to a Belgian study [2], percentages of the patients who have returned to work are as follows: 14.4% of the patients who had discectomy, 22.7% of the patients Almost a half of the patients (27 people), i.e. 44%, intend to apply for a disability pension.…”
