Pain trajectories after bilateral orthotopic lung transplantation surgery performed via a clamshell incision.

INTRODUCTION: The nature, intensity, and progression of acute pain after bilateral orthotopic lung transplantation (BOLT) performed via a clamshell incision has not been well investigated. We aimed to describe acute pain after clamshell incisions using pain trajectories for the study cohort, in addition to stratifying patients into separate pain trajectory groups and investigating their association with donor and recipient perioperative variables. METHODS: After obtaining IRB approval, we retrospectively included all patients ≥18 years old who underwent primary BOLT via clamshell incision at a single center between January 1, 2017, and June 30, 2022. We modeled the overall pain trajectory using pain scores collected over the first seven postoperative days and identified separate pain trajectory classes via latent class analysis. RESULTS: Three hundred one adult patients were included in the final analysis. Three separate pain trajectory groups were identified, with most patients (72.8%) belonging to a well-controlled, stable pain trajectory. Uncontrolled pain was either observed in the early postoperative period (10%), or in the late postoperative period (17.3%). Late postoperative peaking trajectory patients were younger (p = .008), and sicker with a higher lung allocation score (p = .005), receiving preoperative mechanical ventilation (p < .001), or VV-ECMO support (p < .001). CONCLUSION: Despite the extensive nature of a clamshell incision, most pain trajectories in BOLT patients had a well-controlled stable pain profile. The benign nature of pain profiles in our patient population may be attributed to the routine institutional practice of early thoracic epidural analgesia for BOLT patients unless contraindicated.

Predictors of Intervention Session Completion in a Randomized Clinical Trial of a Behavioral Cancer Pain Intervention.

CONTEXT: Some patients with cancer are able to complete psychosocial pain management intervention sessions, and others find it difficult to do so. OBJECTIVES: Conduct a secondary analysis of a randomized clinical trial (N = 178) that compared delivery formats (in-person vs. videoconference) of a pain coping skills training (PCST) intervention for patients with cancer to examine if intervention session completion predicts postintervention outcomes of pain severity and interference, psychological distress, physical well-being, and pain self-efficacy; and identify predictors (i.e., demographics, medical characteristics, baseline outcome scores) of session completion. METHODS: Session completion (i.e., completing all four sessions vs. missing at least one session) was tested as a predictor of postintervention outcomes. Predictors of session completion were then examined. RESULTS: In both study conditions combined, PCST session completion predicted improvement from baseline to postintervention in pain severity (ß = -0.27; P = 0.03), pain interference (ß = -0.25; P = 0.048), and pain self-efficacy (ß = 0.23; P = 0.07). Participants in the videoconference condition were significantly more likely than those in the in-person condition to complete all sessions (83% vs. 65%; P = 0.006). Participants with at least some college education (odds ratio [OR] 4.36; P = 0.04), a diagnosis of breast cancer (OR 6.73; P = 0.04), and higher levels of pain self-efficacy (OR 2.32; P = 0.02) were more likely to complete videoconference sessions. Participants who lived closer to the medical center (OR 0.64; P = 0.07), had early stage cancer (OR 3.82; P = 0.07), and fewer medical comorbidities (OR 0.59; P = 0.04) were more likely to complete in-person sessions. CONCLUSION: Completing PCST sessions is important for improving pain outcomes. Efforts to increase session completion (e.g., videoconference delivery) should be considered.

A behavioral cancer pain intervention: A randomized noninferiority trial comparing in-person with videoconference delivery.

OBJECTIVE: Behavioral cancer pain interventions are efficacious for improving important pain outcomes; yet, traditional in-person delivery limits patient access. This study compared videoconference-delivered mobile health pain coping skills training (mPCST) to in-person pain coping skills training (PCST-traditional). METHODS: This study was a randomized, noninferiority trial with cancer patients. Participants (N = 178) were randomly assigned to four, 45-minute sessions of mPCST or PCST-traditional. Session content focused on evidence-based cognitive and behavioral pain management skills. Assessments were completed at baseline, posttreatment, and 3-month posttreatment, and included measures of primary intervention outcomes (ie, pain severity and pain interference) and secondary intervention outcomes (ie, physical symptoms, psychological distress, physical well-being, and self-efficacy). The main study aim tested whether mPCST was more accessible (defined as feasibility, acceptability, patient burden, and engagement) than PCST-traditional. The second aim tested whether mPCST was noninferior to PCST-traditional. RESULTS: mPCST demonstrated significantly greater feasibility (ie, attrition, adherence, and time to completion) than PCST-traditional. Both groups reported similar patient burden and engagement as well as a high degree of acceptability. All intervention outcomes demonstrated noninferiority at posttreatment and, with the exception of physical symptoms, 3-month posttreatment. Concerning the primary intervention outcomes, 95% CIs for the mean differences (d) were below the noninferiority margin of 1 for pain severity (posttreatment d = 0.09, 95% CI, -0.63-0.81; 3 months d = -0.43 95% CI, -1.22-0.36) and pain interference (posttreatment d = -0.11, 95% CI, -0.99-0.76; 3 months d = -0.26 95% CI, -1.14-0.62). CONCLUSION: mPCST is highly accessible and noninferior to PCST-traditional.

Depression, social support, and clinical outcomes following lung transplantation: a single-center cohort study.

Depressive symptoms are common among lung transplant candidates and have been associated with poorer clinical outcomes in some studies. Previous studies have been plagued by methodologic problems, including small sample sizes, few clinical events, and uncontrolled confounders, particularly perioperative complications. In addition, few studies have examined social support as a potential protective factor. We therefore examined the association between pretransplant depressive symptoms, social support, and mortality in a large sample of lung transplant recipients. As a secondary aim, we also examined the associations between psychosocial factors, perioperative outcomes [indexed by hospital length of stay (LOS)], and mortality. We hypothesized that depression would be associated with longer LOS and that the association between depression, social support, and mortality would be moderated by LOS. Participants included lung transplant recipients, transplanted at Duke University Medical Center from January 2009 to December 2014. Depressive symptoms were evaluated using the Beck Depression Inventory (BDI-II) and social support using the Perceived Social Support Scale (PSSS). Medical risk factors included forced vital capacity (FVC), partial pressure of carbon dioxide (PCO2 ), donor age, acute rejection, and transplant type. Functional status was assessed using six-minute walk distance (6MWD). We also controlled for demographic factors, including age, gender, and native disease. Transplant hospitalization LOS was examined as a marker of perioperative clinical outcomes. Participants included 273 lung recipients (174 restrictive, 67 obstructive, 26 cystic fibrosis, and six "other"). Pretransplant depressive symptoms were common, with 56 participants (21%) exhibiting clinically elevated levels (BDI-II ≥ 14). Greater depressive symptoms were associated with longer LOS [adjusted b = 0.20 (2 days per 7-point higher BDI-II score), P < 0.01]. LOS moderated the associations between depressive symptoms (P = 0.019), social support (P < 0.001), and mortality, such that greater depressive symptoms and lower social support were associated with greater mortality only among individuals with longer LOS. For individuals with LOS ≥ 1 month, clinically elevated depressive symptoms (BDI-II ≥ 14) were associated with a threefold increased risk of mortality (HR = 2.97). Greater pretransplant depressive symptoms and lower social support may be associated with greater mortality among a subset of individuals with worse perioperative outcomes.

Enhancing Cardiac Rehabilitation With Stress Management Training: A Randomized, Clinical Efficacy Trial.

BACKGROUND: Cardiac rehabilitation (CR) is the standard of care for patients with coronary heart disease. Despite considerable epidemiological evidence that high stress is associated with worse health outcomes, stress management training (SMT) is not included routinely as a component of CR. METHODS AND RESULTS: One hundred fifty-one outpatients with coronary heart disease who were 36 to 84 years of age were randomized to 12 weeks of comprehensive CR or comprehensive CR combined with SMT (CR+SMT), with assessments of stress and coronary heart disease biomarkers obtained before and after treatment. A matched sample of CR-eligible patients who did not receive CR made up the no-CR comparison group. All participants were followed up for up to 5.3 years (median, 3.2 years) for clinical events. Patients randomized to CR+SMT exhibited greater reductions in composite stress levels compared with those randomized to CR alone (P=0.022), an effect that was driven primarily by improvements in anxiety, distress, and perceived stress. Both CR groups achieved significant, and comparable, improvements in coronary heart disease biomarkers. Participants in the CR+SMT group exhibited lower rates of clinical events compared with those in the CR-alone group (18% versus 33%; hazard ratio=0.49; 95% confidence interval, 0.25-0.95; P=0.035), and both CR groups had lower event rates compared with the no-CR group (47%; hazard ratio=0.44; 95% confidence interval, 0.27-0.71; P<0.001). CONCLUSIONS: CR enhanced by SMT produced significant reductions in stress and greater improvements in medical outcomes compared with standard CR. Our findings indicate that SMT may provide incremental benefit when combined with comprehensive CR and suggest that SMT should be incorporated routinely into CR.
