Quantifying value loss due to presenteeism and absenteeism in workers' compensation spinal patients.

BACKGROUND

Recent studies suggest that better outcomes in work productivity following spine surgery eventually offset the higher cost of treatment. By analyzing preoperative and postoperative changes in work productivity, studies can determine if surgery is cost-effective and give patients valuable information about treatment. Prior studies reviewing outcomes in work performance after spine surgery have largely excluded patients on workers' compensation from the overall cost analysis.

METHODS

A retrospective review of 92 eligible patients was conducted. Evaluation of the EHR identified presenteeism and absenteeism from designated work restrictions. Statistical analyses were conducted using JMP Pro 17.

RESULTS

About 84 (83%) spinal surgery cases were able to return to work, 60 (59%) were able to return to work with no restrictions, 26 (26%) received permanent work restrictions, and 12 (12%) were still undergoing treatment. 86 (85%) experienced presenteeism and 99 (98%) experienced absenteeism. Of the cases that were able to return to work without permanent work restrictions, the mean presenteeism length postoperatively was 287.4 days (median 191 days) and the mean absenteeism length postoperatively was 232.5 days (median 142 days). 72 patients were identified as having sedentary or nonsedentary labor. After excluding outliers, the average return-to-work length was 988.62 days for patients with sedentary employment types and 952.15 days for patients with nonsedentary employment types (p=.116).

CONCLUSION

Following spinal surgery, our worker's compensation patient population's return-to-work rate was at an average of 232.5 days (median of 142 days) for 83% of patients included in this study. This exhibited worse outcomes than a previous study's measurement excluding worker's compensation patients. Presenteeism length within our population contributed more to decreased work productivity postoperatively than absenteeism length. Our results found no significant difference in return-to-work length between patients with sedentary and nonsedentary employment types.
