Objectives: Joint pain and radiographic osteoarthritis are often discordant. Aim: To investigate this issue more closely by studying the detailed nature of pain and disability, and how this relates to radiographic osteoarthritis. Methods: Population-based study of 819 adults aged >50 years with knee pain. The severity of knee pain, stiffness and disability was measured using a validated scale (the Western Ontario and McMaster Universities (WOMAC) Score) and pain persistence was recorded. Global severity was measured by the graded chronic pain scale. Three radiographic views of the knees were obtained-weight-bearing posteroanterior metatarsophalangeal, supine skyline and supine lateral. Results: 745 participants with knee pain in the past 6 months were eligible (mean age 65 years, 338 men). Radiographic osteoarthritis was more common in those with a longer history and more persistent symptoms. A strong trend was found of radiographic osteoarthritis being more strongly associated with higher WOMAC scores for pain severity, stiffness and disability (adjusted odds ratio (95% confidence interval (CI)) for highest v lowest WOMAC category: 3.7 (2.0 to 6.7), 3.0 (2.0 to 4.6) and 2.8 (1.6 to 5.0), respectively). Those individual WOMAC items for pain and disability pertaining to weight-bearing mobility were the most strongly associated with radiographic osteoarthritis. Combining pain persistence and global severity, persistent severe pain was associated with a significant increase in the occurrence of radiographic osteoarthritis (2.6 (95% CI 1.5 to 4.7)). Conclusions: A consistent association was found between severity of pain, stiffness and physical function and the presence of radiographic osteoarthritis. This study highlights the potential contribution of underlying joint disease to the degree of pain and disability.
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.
Background Early convalescent plasma transfusion may reduce mortality in patients with non-severe coronavirus disease 2019 (COVID-19). Methods This study emulates a (hypothetical) target trial using observational data from a cohort of United States Veterans admitted to a Department of Veterans Affairs (VA) facility between May 1 and November 17, 2020 with non-severe 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 4,755 patients, 402 trials were assigned to the convalescent plasma group. Forty and 671 deaths occurred within the plasma and non-plasma groups, respectively. The estimated 30-day mortality risk was 6.5% (95% CI: 4.0, 9.7) in the plasma group and 6.2% (95% CI: 5.6, 7.0) in the non-plasma group. The associated risk difference was 0.30% (95% CI -2.30, 3.60) and the hazard ratio was 1.04 (95% CI 0.64,1.62). Conclusion Our target trial emulation estimated no meaningful differences in 30-day mortality between non-severe COVID-19 patients treated and untreated with convalescent plasma.
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.
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 (aOR: 1.37, 95% 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.
