According to new IWH research, workplace-based programs in which workers and supervisors jointly identify and solve return-to-work barriers help workers with low-back pain return to their jobs more quickly — especially workers who are often considered the most challenging return-to-work cases.
Here’s the good news: Implementing a workplace-based program for workers who are absent due to low-back pain will help them return to work faster.
Here’s the even better news: That same program will be particularly effective for workers often considered hard to return — older workers and those who have previously been off sick.
These are the findings of Institute for Work & Health (IWH) Scientist Dr. Ivan Steenstra, published in the May 2009 issue of Spine (vol. 34, no. 12, pp. 1243-1249). He came to these conclusions based on a study he carried out in the Netherlands while earning his PhD and then continued as a researcher at IWH.
The results suggest a lot of progress can be made helping injured workers return to their jobs with a good workplace-based intervention, especially among those workers usually considered challenging cases, says Steenstra.
Worksite program beats usual care
So what, exactly, does this return-to-work (RTW) program for workers with non-specific low-back pain look like? As Steenstra explains, it’s based on the “Sherbrooke model,” which refers to a program developed in Canada by Dr. Patrick Loisel and fellow researchers at Sherbrooke University. It involves the worker and the supervisor, with the help of an occupational health professional or ergonomist, identifying and solving RTW barriers, and then implementing the solutions in the workplace (see details).
Steenstra initially compared the results of this program with “usual care” among workers who had been off work for two to six weeks due to low-back injury. “Usual care” referred to being under the care of an occupational health physician only, without the worksite intervention.
The results were definitive. The workers in the worksite-based program returned to work faster than those who received usual care only. They returned to work 30 days earlier, on average, than the usual-care group and at only slightly higher cost.
Older and previously sick workers best served
This led Steenstra to wonder, “Does this workplace intervention work better for some rather than others?” So he dug deeper into his findings. He discovered that factors such as gender, functional status, pain and heavy work did not make a difference to the program’s effectiveness. However, two factors did — age and sick leave taken in the previous year.
Workers aged 44 years and over who took part in the workplace-based program returned to work 2.5 times faster than workers the same age in the usual-care group. Workers who were sick in the previous year who took part in the program returned to work 2.8 times faster than workers who had been sick and received usual care.
There might be a tendency to not bother investing in older and previously sick workers because they’re considered too difficult to return to work, Steenstra says.
But according to this study, that’s the wrong way to think. This analysis suggests a lot of progress can be made with a good intervention, especially among those considered challenging cases.
