Using the Quebec Task Force Classification system to Categorize patients with occupational low back pain

Quebec Task Force Classification (QTFC) and pain routine classification (PPC) processes, such as centralization and non-centralization, are typical classification processes. The classification was performed to gauge the validity of information acquired with QTFC and PPC processes for identifying patient subgroups at ingestion and to be used in forecasting rehabilitation outcomes at release and work status at 1 year following discharge from rehab.

Patients (n=171, 54 percent male; mean age=37 decades, SD=10, range=18-62) with severe work-related lower back pain known as physical therapy were examined.

Patients finished melancholy and psychosocial questionnaires at first examination and release and painkillers during the intervention. Physical therapists categorized patients utilizing QTFC and PPC information at intake. Patients have categorized again at release by PPC (time-dependent PPC).

Quebec Task Force Classification


Analysis of variance of revealed QTFC and PPC information can be used to distinguish patients by pain intensity or handicap in the intake. Analysis of covariance revealed that ingestion PPC predicted pain intensity and disability at release, but QTFC didn’t. Logistic regression revealed that PPC predicted function status at 1 year, but QTFC didn’t. Classifying patients over the years utilizing time-dependent PPC data decreased the false positive rate by 31 percent and increased the percent of the shift in a pretest-posttest likelihood of the return to work by 16 percent compared with classifying patients in the intake.

The Quebec Task Force on Whiplash-Associated Disorders and the British Columbia Whiplash Initiative: A Study of Insurance Industry Initiatives

Two research on whiplash-associated ailments which were generated by insurance companies were evaluated. The British Columbia Whiplash Initiative (BCWI) propagated the QTF recommendations. The Quebec Task Force Cohort Study: This study was developed to determine retrospectively the natural history of whiplash accidents, however, recovery from whiplash injuries was determined by the discontinuation of payments rather than by the resolution of symptoms. Patients complaining of’recurrences’, who included a substantial percentage of the total amount of patients studied, were specifically excluded from the data set. When these patients were contained in the data collection, the proportion of patients who failed to recover (based on whether they were receiving reimbursement ) had risen from the reported 2.9percent to as high as 12.4% after a year. It’s not possible to draw valid conclusions about the history of whiplash injuries from this study since it did not research recovery from whiplash symptoms and excluded nearly all patients who were classified as’recurrences’ by the final study analysis. The Quebec Task Force Best Evidence Synthesis Including Interventions: This analysis identified the paucity of conclusive research concerning remedies for whiplash. The paucity of conclusive research limited the number of decisions that may be drawn. The Quebec Task Force Consensus Recommendations: Despite a recognized lack of quality research, a consensus report that focused on curative interventions was created. This consensus report is of concern since there was limited evidence to support the consensus, the classifications and recommendations were entirely arbitrary, the cohort data that the consensus panel relied upon to identify a pure history was seriously flawed, funds for the analysis was partisan, there was possibility of misuse of guidelines, and there was a failure to manage chronic whiplash accidents. The British Columbia Whiplash Initiative: This report, which was designed as a set of educational modules, relied heavily on the QTF, particularly the cohort study along with the consensus recommendations. Because of this, the report has been based upon a flawed and overly optimistic picture of the history of whiplash disorders, and an arbitrary classification and management system. The QTF and the BCWI draw attention to the possible dangers of insurance industry initiatives designed to persuade medical and allied health professionals to accept perspectives that appear overoptimistic and potentially self-serving.

Discussion and conclusion of the Quebec Task Force Classification:

Results support the discriminant validity of their QTFC information at intake and predictive validity of the PPC information at intake. Tracking PPC over the years raises predictive validity for 1-year function standing.
