Validating Goal Attainment in Veterans Undergoing Decompressive Laminectomy: A Preliminary Study.

OBJECTIVE

Although decompressive laminectomy (DL) for lumbar spinal stenosis (LSS) is a common procedure among older adults, it is unclear whether surgical definitions of success translate into patient-defined success. Using goal attainment scaling (GAS) to compare goal achievement between individuals, we investigated the relationship between surgical-defined functional recovery and achievement of personalized goals in patients who underwent DL for LSS.

PARTICIPANTS

Twenty-eight community-dwelling veterans scheduled to undergo DL.

METHODS

Participants were interviewed over the phone to set 1-year post-DL goals within 30 days before undergoing DL. Brigham Spinal Stenosis (BSS) score, comorbidities, cognitive function, and psychological factors also were assessed. GAS and BSS were repeated 1 year after DL. GAS scores were transformed into GAS-T scores (T-score transformation) to standardize achievement between patients and GAS-T change scores to compare study variables.

RESULTS

Seventeen of 28 participants had successful DL outcomes by BSS standards, though none of the participants achieved all of their GAS goals, with follow-up GAS-T scores averaging 44.5 ± 16.8. All three BSS scales positively correlated with GAS-T change scores: severity change r = 0.52, P = 0.005; physical function change r = 0.51, P = 0.006; and satisfaction r = 0.70, P < 0.001. Covariate analysis revealed a negative correlation between GAS-T change score and fear-avoidance beliefs: r = -0.41, P = -0.029.

CONCLUSION

There was congruent validity between GAS and the BSS in older veterans undergoing DL for LSS. Given the need for patient-centered care in older adults, future investigations exploring GAS in larger studies that target additional pain conditions and include participants with greater demographic diversity are warranted.
