Locking-In Effects Due to Early Interventions? An Evaluation of a Multidisciplinary Screening Programs for Avoiding Long-Term Sickness

Abstract

Objective:

In this article, we estimate the effect of a multidisciplinary collaborationprogram on the length of sickness absence. The intention with the programwas to avoid long-term sickness absence by providing an early and holistic evaluation of the sick-listed individuals' conditions. The target group was individuals who were at risk of becoming long-term sick. The eligibility criteria were mainly based on register information that we have access to.

Methods:

Using this register information, we estimate different Cox regression models and apply a nonparametric matching estimator. We have also conducted a small randomized experiment.

Results:

The result from the randomized experiment is not statistically significant, but the point estimate provides the same result as was found in the observational study: The program prolongs rather than shortens the sickness absence spell. That is, the average sickness absence spell is prolonged by about 3 months.

Conclusions:

Our main explanation for this discouraging result is that the team focuses too much on rehabilitation rather than encouraging the sick-listed individual to return to work.
