Physical therapy utilization, costs, and return-to-work status following lumbar spine surgery: A retrospective analysis of workers compensation claims in Australia.

ABSTRACT:

Background

No study to our knowledge has explored physical therapy utilization following lumbar spine surgery in a workers' compensation setting.

Objectives

Describe physical therapy utilization and costs, and return-to-work status in patients following lumbar spine surgery under a workers' compensation claim.

Methods

Using data from the New South Wales (NSW) State Insurance Regulatory Authority (Australia), we audited physical therapy billing codes for patients who received lumbar spine surgery from 2010 to 2017. We summarised, by fusion versus decompression, the number of physical therapy sessions patients received up to 12 months post-operatively, total cost of physical therapy and time to initiation of physical therapy. Number of physical therapy sessions and physical therapy utilization at 12 months were summarised by return-to-work status at 12 months.

Results

We included 3524 patients (1220 had fusion; 2304 decompression). On average, patients received 22 ± 22 physical therapy sessions to 12 months post-operatively (mean cost=AU$1902, US$1217); 24% were receiving physical therapy at 12 months. Most had 9-24 (31%) or 25-50 sessions (25%); 11% had > 50 sessions, whereas 11% had no physical therapy. Patients who had fusion (compared to decompression) had more physical therapy and incurred higher physical therapy costs. Time post-surgery to initiate physical therapy increased from 2010 to 2017. Patients with > 50 sessions and still having physical therapy by 12 months were least likely to be working.

Conclusions

For most patients, physical therapy utilization following lumbar spine surgery aligns with the best available evidence. However, some patients may be receiving too much physical therapy or initiating physical therapy too early.

Project description:BackgroundUnderstanding how much physiotherapy people receive before lumbar spine surgery could give insight into what people and clinicians consider an adequate trial of non-operative management. The aim of this study was to investigate physiotherapy utilisation and costs before lumbar spine surgery under a workers' compensation claim in New South Wales (NSW), Australia.MethodsUsing data from the NSW State Insurance Regulatory Authority, we audited physiotherapy billing codes used before surgery for people who received lumbar spine surgery from 2010 to 2018. We summarised, separately for fusion and decompression, the time from initiation of physiotherapy to surgery, number of physiotherapy sessions people received before surgery, total cost of physiotherapy before surgery, and time from injury date to initiation of physiotherapy. All analyses were descriptive.ResultsWe included 3070 people (800 had fusion, 2270 decompression). Mean age (standard deviation, SD) was similar between those who received fusion and decompression [42.9 (10.4) vs. 41.9 (11.6)]. Compared to people who had fusion, those who had decompression were more likely to not have any physiotherapy before surgery (28.4% vs. 15.4%), received physiotherapy for a shorter duration before surgery [median (interquartile range, IQR): 5 (3 to 11) vs. 15 (4-26) months], were less likely to have physiotherapy for ≥2 years before surgery (5.6% vs. 27.5%), had fewer physiotherapy sessions before surgery [mean (SD): 16 (21) vs. 28 (35) sessions], were less likely to have > 50 physiotherapy sessions before surgery (6.8% vs. 18.1%), and had lower total physiotherapy-related costs [mean (IQR): $1265 ($0-1808) vs. $2357 ($453-2947)]. Time from injury date to first physiotherapy session was similar between people who had fusion and decompression [median (IQR): 23 (9-66) vs.19 (7-53) days].ConclusionsThere is variation in physiotherapy utilisation and costs before lumbar spine surgery for people funded by NSW Workers' Compensation. Some people may not be receiving an adequate trial of physiotherapy before surgery, particularly before decompression surgery. Others may be receiving an excessive amount of physiotherapy before surgery, particularly before fusion.

Project description:BackgroundInternationally, elective spinal surgery rates in workers' compensation populations are high, as are reoperation rates, while return-to-work rates following spinal surgery are low. Little information is available from Australia. The aim of this study was to describe the rates, costs, return to work and reoperation following elective spinal surgery in the workers' compensation population in New South Wales (NSW), Australia.MethodsThis retrospective cohort study used administrative data from the State Insurance Regulatory Authority, the government organisation responsible for regulating and administering workers' compensation insurance in NSW. These data cover all workers' compensation-insured workers in New South Wales (over 3 million workers/year). We identified a cohort of insured workers who underwent elective spinal surgery (fusion or decompression) between January 1, 2010 and December 31, 2018. People who underwent surgery for spinal fracture or dislocation, or who had sustained a traumatic brain injury were excluded. The main outcome measures were annual spinal surgery rates, cost of the surgical episode, cumulative costs (surgical, hospital, medical and physical therapy) to 2 years post-surgery, and reoperation and return-to-work rates 2 years post-surgery.ResultsThere were 9343 eligible claims (39.1 % fusion; 59.9 % decompression); claimants were predominantly male (75 %) with a mean age of 43 (range 18 to 75) years. Spinal surgery rates ranged from 15 to 29 surgeries per 100,000 workers per year, fell from 2011-12 to 2014-15 and rose thereafter. The average cost in Australian dollars for a surgical episode was $46,000 for a spinal fusion and $20,000 for a decompression. Two years post-fusion, only 19 % of people had returned to work at full capacity; 39 % after decompression. Nineteen percent of patients underwent additional spinal surgery within 2 years of the index surgery, to a maximum of 5 additional surgeries.ConclusionRates of workers' compensation-funded spinal surgery did not rise significantly during the study period, but reoperation rates are high and return-to-work rates are low in this population at 2 years post- surgery. In the context of the poor evidence base supporting lumbar fusion surgery, the high cost, increasing rates, and the increased likelihood of poor outcomes in the workers' compensation population, we question the value of this procedure in this setting.
