RESUMEN
OBJECTIVE: Chronic pain is more common among veterans than among the general population. Expert guidelines recommend multimodal chronic pain care. However, there is substantial variation in the availability and utilization of treatment modalities in the Veterans Health Administration. We explored health care providers' and administrators' perspectives on the barriers to and facilitators of multimodal chronic pain care in the Veterans Health Administration to understand variation in the use of multimodal pain treatment modalities. METHODS: We conducted semi-structured qualitative interviews with health care providers and administrators at a national sample of Veterans Health Administration facilities that were classified as either early or late adopters of multimodal chronic pain care according to their utilization of nine pain-related treatments. Interviews were conducted by telephone, recorded, and transcribed verbatim. Transcripts were coded and analyzed through the use of team-based inductive and deductive content analysis. RESULTS: We interviewed 49 participants from 25 facilities from April through September of 2017. We identified three themes. First, the Veterans Health Administration's integrated health care system is both an asset and a challenge for multimodal chronic pain care. Second, participants discussed a temporal shift from managing chronic pain with opioids to multimodal treatment. Third, primary care teams face competing pressures from expert guidelines, facility leadership, and patients. Early- and late-adopting sites differed in perceived resource availability. CONCLUSIONS: Health care providers often perceive inadequate support and resources to provide multimodal chronic pain management. Efforts to improve chronic pain management should address both organizational and patient-level challenges, including primary care provider panel sizes, accessibility of training for primary care teams, leadership support for multimodal pain care, and availability of multidisciplinary pain management resources.

BACKGROUND: There is inadequate evidence of long-term benefit from opioid medications for chronic pain and substantial evidence of potential harms. For patients, dose reduction may be beneficial when implemented voluntarily and supported by a multidisciplinary team but experts have advised against involuntary opioid reduction. OBJECTIVES: To assess the prevalence of self-reported involuntary opioid reduction and to examine whether involuntary opioid reduction is associated with changes in pain severity. DESIGN: Prospective observational cohort study. PARTICIPANTS: Primary care patients treated with long-term opioid therapy in the Veterans Health Administration (N = 290). MAIN MEASURES: The primary exposure was self-reported past year involuntary opioid reduction. The primary outcome was the three-item PEG scale, which measures past-week average pain intensity and interference with enjoyment of life and general activity. KEY RESULTS: Past year opioid reduction or discontinuation was reported by 63% (184/290). Similar numbers reported involuntary (88/290) and voluntary (96/290) opioid reduction. At baseline, there were no significant differences in pain severity between the groups (mean PEG, 7.08 vs. 6.73 vs. 7.07 for past year involuntary opioid reduction, past year voluntary opioid reduction, and no past year opioid reduction, respectively; P = 0.32). For the primary outcome of change in pain severity from baseline to 18 months, there were no significant differences between groups (mean PEG change, - 0.05 vs. - 0.44 vs. - 0.23 for past year involuntary opioid reduction, past year voluntary opioid reduction, and no past year opioid reduction, respectively; P = 0.28). CONCLUSIONS: Self-reported past year involuntary opioid reduction was common among a national sample of veterans treated with long-term opioid therapy. Opioid dose reduction, whether involuntary or voluntary, was not associated with change in pain severity. Future studies should examine involuntary opioid reduction in different populations and trends over time and explore further patient- and provider-level factors that may impact patient experience and outcomes during opioid reduction.

BACKGROUND: Expert guidelines recommend non-pharmacologic treatments and non-opioid medications for chronic pain and recommend against initiating long-term opioid therapy (LTOT). OBJECTIVE: We examined whether veterans with incident chronic pain receiving care at facilities with greater utilization of non-pharmacologic treatments and non-opioid medications are less likely to initiate LTOT. DESIGN: Retrospective cohort study PARTICIPANTS: Veterans receiving primary care from a Veterans Health Administration facility with incident chronic pain between 1/1/2010 and 12/31/2015 based on either of 2 criteria: (1) persistent moderate-to-severe patient-reported pain and (2) diagnoses "likely to represent" chronic pain. MAIN MEASURES: The independent variable was facility-level utilization of pain-related treatment modalities (non-pharmacologic, non-opioid medications, LTOT) in the prior calendar year. The dependent variable was patient-level initiation of LTOT (≥ 90 days within 365 days) in the subsequent year, adjusting for patient characteristics. KEY RESULTS: Among 1,094,569 veterans with incident chronic pain from 2010 to 2015, there was wide facility-level variation in utilization of 10 pain-related treatment modalities, including initiation of LTOT (median, 16%; range, 5-32%). Veterans receiving care at facilities with greater utilization of non-pharmacologic treatments were less likely to initiate LTOT in the year following incident chronic pain. Conversely, veterans receiving care at facilities with greater non-opioid and opioid medication utilization were more likely to initiate LTOT; this association was strongest for past year facility-level LTOT initiation (adjusted rate ratio, 2.10; 95% confidence interval, 2.06-2.15, top vs. bottom quartile of facility-level LTOT initiation in prior calendar year). CONCLUSIONS: Facility-level utilization patterns of non-pharmacologic, non-opioid, and opioid treatments for chronic pain are associated with subsequent patient-level initiation of LTOT among veterans with incident chronic pain. Further studies should seek to understand facility-level variation in chronic pain care and to identify facility-level utilization patterns that are associated with improved patient outcomes.

BACKGROUND: Chronic pain is among the most common conditions presenting to primary care and guideline-based care faces several challenges. A novel pain management program, Video-Telecare Collaborative Pain Management (VCPM), was established to support primary care providers and meet new challenges to care presented by the COVID-19 pandemic. METHODS: The present single-arm feasibility study aimed to evaluate the feasibility and acceptability of VCPM and its components among U.S. veterans on long-term opioid therapy for chronic pain at ≥ 50 mg morphine equivalent daily dose (MEDD). VCPM consists of evidence-based interventions, including opioid reassessment and tapering, rotation to buprenorphine and monitoring, and encouraging behavioral pain and opioid-use disorder self-management. RESULTS: Of the 133 patients outreached for VPCM, 44 completed an initial intake (33%) and 19 attended multiple VCPM appointments (14%). Patients were generally satisfied with VCPM, virtual modalities, and provider interactions. Nearly all patients who attended multiple appointments maintained a buprenorphine switch or tapered opioids (16/19; 84%), and buprenorphine switches were generally reported as acceptable by patients. Patients completing an initial intake with VCPM had reduced morphine equivalent daily dose after three months (means = 109 mg MEDD vs 78 mg), with greater reductions among those who attended multiple appointments compared to intake only (ΔMEDD = -58.1 vs. -8.40). Finally, 29 referrals were placed for evidence-based non-pharmacologic interventions. CONCLUSION: Pre-defined feasibility and acceptability targets for VCPM and its components were broadly met, and preliminary data are encouraging. Novel strategies to improve enrollment and engagement and future directions are discussed.

Pseudomonas aeruginosa is a prime opportunistic pathogen, one of the most important causes of hospital-acquired infections and the major cause of morbidity and mortality in cystic fibrosis lung infections. One reason for the bacterium's pathogenic success is the large array of virulence factors that it can employ. Another is its high degree of intrinsic and acquired resistance to antibiotics. In this review, we first summarise the current knowledge about the regulation of virulence factor expression and production. We then look at the impact of sub-MIC antibiotic exposure and find that the virulence-antibiotic interaction for P. aeruginosa is antibiotic-specific, multifaceted, and complex. Most studies undertaken to date have been in vitro assays in batch culture systems, involving short-term (<24 h) antibiotic exposure. Therefore, we discuss the importance of long-term, in vivo-mimicking models for future work, particularly highlighting the need to account for bacterial physiology, which by extension governs both virulence factor expression and antibiotic tolerance/resistance.
