Telehealth and Rural-Urban Differences in Receipt of Pain Care in the Veterans Health Administration.

OBJECTIVE: Examine changes in specialty pain utilization in the Veterans Health Administration (VHA) after establishing a virtual interdisciplinary pain team (TelePain). DESIGN: Retrospective cohort study. SETTING: A single VHA healthcare system, 2015-2019. SUBJECTS: 33,169 patients with chronic pain-related diagnoses. METHODS: We measured specialty pain utilization (in-person and telehealth) among patients with moderate to severe chronic pain. We used generalized estimating equations to test the association of time (pre- or post-TelePain) and rurality on receipt of specialty pain care. RESULTS: Among patients with moderate to severe chronic pain, the reach of specialty pain care increased from 11.1% to 16.2% in the pre- to post-TelePain periods (adjusted odds ratio [aOR]: 1.37, 95% confidence interval [CI]: 1.26-1.49). This was true of both urban patients (aOR: 1.62, 95% CI: 1.53-1.71) and rural patients (aOR: 1.16, 95% CI: 0.99-1.36), although the difference for rural patients was not statistically significant. Among rural patients who received specialty pain care, a high percentage of the visits were delivered by telehealth (nearly 12% in the post-TelePain period), much higher than among urban patients (3%). CONCLUSIONS: We observed increased use of specialty pain services among all patients with chronic pain. Although rural patients did not achieve the same degree of access and utilization overall as urban patients, their use of pain telehealth increased substantially and may have substituted for in-person visits. Targeted implementation efforts may be needed to further increase the reach of services to patients living in areas with limited specialty pain care options.

Early Convalescent Plasma Therapy and Mortality Among US Veterans Hospitalized With Nonsevere COVID-19: An Observational Analysis Emulating a Target Trial.

BACKGROUND: Early convalescent plasma transfusion may reduce mortality in patients with nonsevere coronavirus disease 2019 (COVID-19). METHODS: This study emulates a (hypothetical) target trial using observational data from a cohort of US veterans admitted to a Department of Veterans Affairs (VA) facility between 1 May and 17 November 2020 with nonsevere COVID-19. The intervention was convalescent plasma initiated within 2 days of eligibility. Thirty-day mortality was compared using cumulative incidence curves, risk differences, and hazard ratios estimated from pooled logistic models with inverse probability weighting to adjust for confounding. RESULTS: Of 11 269 eligible person-trials contributed by 4755 patients, 402 trials were assigned to the convalescent plasma group. Forty and 671 deaths occurred within the plasma and nonplasma groups, respectively. The estimated 30-day mortality risk was 6.5% (95% confidence interval [CI], 4.0%-9.7%) in the plasma group and 6.2% (95% CI, 5.6%-7.0%) in the nonplasma group. The associated risk difference was 0.30% (95% CI, -2.30% to 3.60%) and the hazard ratio was 1.04 (95% CI, .64-1.62). CONCLUSIONS: Our target trial emulation estimated no meaningful differences in 30-day mortality between nonsevere COVID-19 patients treated and untreated with convalescent plasma.

Patient Feedback on the Effectiveness of Auricular Acupuncture on Pain in Routine Clinical Care: The Experience of 11,406 Veterans.

OBJECTIVES: Veterans Health Administration (VHA) launched a national initiative to train providers in a specific, protocolized auricular acupuncture treatment (also called Battlefield Acupuncture or BFA) as a nonpharmacological approach to pain management. This evaluation assessed the real-world effectiveness of BFA on immediate pain relief and identified subgroups of patients for whom BFA is most effective. RESEARCH DESIGN: In a cross-sectional cohort study, electronic medical record data for 11,406 Veterans treated with BFA at 57 VHA medical centers between October 2016 and September 2018 was analyzed. The multivariate analysis incorporated data on pain history, change in pain level on an 11-point scale, complications, and demographic information. METHODS: A total of 11,406 Veterans were treated with BFA at 57 VHA medical centers between October 2016 and September 2018 and had effectiveness data recorded in their electronic medical record. RESULTS: More than 3 quarters experienced immediate decreases in pain following administration of BFA, with nearly 60% reported experiencing a minimal clinically important difference in pain intensity. The average decrease in pain intensity was -2.5 points (SD=2.2) at the initial BFA treatment, and -2.2 points (SD=2.0) at subsequent treatments. BFA was effective across a wide range of Veterans with many having preexisting chronic pain, or physical, or psychological comorbid conditions. Veterans with opioid use in the year before BFA experienced less improvement, with pain intensity scores improving more among Veterans who had not recently used opioids. CONCLUSION: VHA's rapid expansion of training providers to offer BFA as a nonpharmacological approach to pain management has benefited many Veterans.

Does Offering Battlefield Acupuncture Lead to Subsequent Use of Traditional Acupuncture?

OBJECTIVES: Veterans Health Administration encourages auricular acupuncture (Battlefield Acupuncture/BFA) as a nonpharmacologic approach to pain management. Qualitative reports highlighted a "gateway hypothesis": providing BFA can lead to additional nonpharmacologic treatments. This analysis examines subsequent use of traditional acupuncture. RESEARCH DESIGN: Cohort study of Veterans treated with BFA and a propensity score matched comparison group with a 3-month follow-up period to identify subsequent use of traditional acupuncture. Matching variables included pain, comorbidity, and demographics, with further adjustment in multivariate regression analysis. SUBJECTS: We identified 41,234 patients who used BFA across 130 Veterans Health Administration medical facilities between October 1, 2016 and March 31, 2019. These patients were matched 2:1 on Veterans who used VA care but not BFA during the same period resulting in a population of 24,037 BFA users and a comparison cohort of 40,358 non-BFA users. Patients with prior use of traditional acupuncture were excluded. RESULTS: Among Veterans receiving BFA, 9.5% subsequently used traditional acupuncture compared with 0.9% of non-BFA users (P<0.001). In adjusted analysis, accounting for patient characteristics and regional availability of traditional acupuncture, patients who used BFA had 10.9 times greater odds (95% confidence interval, 8.67-12.24) of subsequent traditional acupuncture use. CONCLUSIONS: Providing BFA, which is easy to administer during a patient visit and does not require providers be formally certified, led to a substantial increase in use of traditional acupuncture. These findings suggest that the value of offering BFA may not only be its immediate potential for pain relief but also subsequent engagement in additional therapies.

Battlefield Acupuncture in the Veterans Health Administration: Effectiveness in Individual and Group Settings for Pain and Pain Comorbidities.

Objective: The Department of Veterans Affairs trained primary-care providers to deliver Battlefield Acupuncture (BFA), a subset of auricular acupuncture, to patients. However, little is known about BFA effectiveness in group or individual sessions or repeated administrations versus singular use. The aim of this study was to examine the use and effectiveness of BFA for back pain and four pain-comorbid conditions in group and individual sessions at a large Veterans Affairs (VA) medical center. Materials and Methods: This cross-sectional study was conducted at the West Haven VA Medical Center, in West Haven CT. Between October 2016 and December 2017, 284 veterans with pain received BFA. The BFA was administered in group clinics or in individual encounters. The Defense and Veterans Pain Rating Scale was used to assess self-reported pain immediately before and after each BFA administration. Results: Over the study period, an average of 57 (range: 50-66) new patients per month received BFA. Of 753 total patient encounters, an immediate decrease in self-reported pain occurred in 616 (82.0%) patients, no change occurred in 73 (9.7%) patients, and an increase occurred in 62 (8.3%) patients. Decreases in pain were common in the group and individual settings, even in patients with originally high pain scores, and the effectiveness remained with repeated uses. Conclusions: BFA can be effective for immediate relief of pain-whether the BFA is administered in a group or individual setting-for the overwhelming majority of veterans and, as such, holds promise as a nonpharmacologic pain-management intervention.
