A Naturalistic Trial of the Norwegian Sickness Absence Clinic. The NSAC Efficacy Study

Summary

The Norwegian Sickness Absence Clinic (NSAC) is a publicly funded specialist outpatient health service, which is uniquely available for the work force. The overall aim of the NSAC is prevention of sickness absence, promote return to work (RTW) among those on sickness absence and prevent long term disability benefit dependency. In addition to being a health service, the NSAC has a focus on work and functional recovery, including also non-health related factors. Patients can be referred by general practitioners for mental health problems and musculoskeletal problems. The NSAC has a lower threshold for severity than specialist health services generally, and in particular for mental health problems. The efficacy of this service is unknown. The NSAC Efficacy Study is a randomized controlled multicentre trial which aims to assess the effect of the NSAC service. "Helse i Arbeid" is the Norwegian name for NSAC, and the Norwegian abbreviation is "HiA". The Norwegian study name is HIANOR. The NSAC Efficacy Study involves five different NSACs across northern Norway, and will recruit 2500 patients, randomized to in equal proportions to three treatment arms: 1. NSAC - rapid: treatment at the NSAC at- or within 4 weeks 2. NSAC - ordinary: treatment at the NSAC after 10-14 weeks 3. NSAC - active control: monodisciplinary examination at the NSAC close to diagnosis-specific deadline for examination as suggested by guidelines (8-26 weeks, the majority at the end of this interval) The overall aim is to assess the effect of the NSAC service, with the hypothesis that the NSAC service is superior to what resembles treatment as usual (TAU) for outcomes such as return to work or improved health (waiting list control). Many of the diagnoses or problems for which patients are referred to the NSACs naturally improve regardless of health interventions, and - as of date - no research has been conducted to assess the efficacy of the service.
