Whole health team intervention reduced pain interference by 0.58 points versus cognitive behavioral therapy in VA patientsA new team approach offers small but real relief for chronic pain in VA patients

This randomized clinical trial evaluated the efficacy of a whole health team intervention for patients with chronic pain. The study population consisted of 764 patients receiving primary care within six Veterans Affairs health systems in the US. Participants were assigned to one of three groups: the whole health team intervention, cognitive behavioral therapy delivered in group sessions, or usual care. The primary outcome measured was the Brief Pain Inventory interference subscale score at 12 months. The follow-up period for the study was 12.0 months.

The whole health team intervention group demonstrated a mean BPI-I subscale score of 4.9 at 12 months, an improvement from a baseline of 6.6. The cognitive behavioral therapy group improved from a baseline of 6.4 to a mean score of 5.5 at 12 months. The usual care group improved from a baseline of 6.4 to a mean score of 5.7 at 12 months. All groups showed some degree of improvement in pain interference scores over the study period.

When comparing the whole health team intervention to cognitive behavioral therapy, the mean difference in BPI-I scores was -0.58. The 97% confidence interval for this difference ranged from -1.11 to -0.05. The p-value was not reported in the provided data. This difference was statistically significant. When comparing the whole health team intervention to usual care, the mean difference was -0.77. The 99% confidence interval for this comparison ranged from -1.40 to -0.15.

In contrast, cognitive behavioral therapy did not improve pain interference scores significantly more than usual care. The mean difference between these two groups was -0.19. The 99% confidence interval for this difference ranged from -0.89 to 0.50. This interval included zero, indicating no statistically significant difference between the cognitive behavioral therapy and usual care groups.

Safety data reported suicidal ideation rates across the study groups. Suicidal ideation occurred in 15.9% of patients in the cognitive behavioral therapy group. The rate was 13.7% in the whole health team group and 13.4% in the usual care group. Serious adverse events were not reported. Discontinuations due to adverse events were not reported. Tolerability details were not reported.

The results support the use of the whole health team approach to attain a statistically significant but small improvement in pain interference in VA patients with chronic pain. The absolute magnitude of the improvement between the whole health team and cognitive behavioral therapy was modest. The confidence intervals for the primary comparisons did not cross zero, confirming statistical significance. However, the clinical relevance of a 0.58 point difference on the BPI-I subscale requires careful interpretation by clinicians.

Limitations of the study include the lack of reported funding or conflicts of interest. The study phase was not reported. The publication type was not reported. Causality was not explicitly reported. These factors suggest caution when generalizing findings to other settings or populations. The study was conducted exclusively within VA health systems, which may limit applicability to non-VA settings.

Future research should investigate whether the whole health team intervention offers advantages over cognitive behavioral therapy in terms of cost, accessibility, or patient preference. The higher rate of suicidal ideation in the cognitive behavioral therapy group warrants attention, though the difference between groups was not statistically significant based on the provided data. Clinicians should consider these findings when selecting pain management strategies for veterans with chronic pain.
