Shifts in Students' Attitudes Towards Pain Patients, Pain, and Opioid Management Following a Dedicated Medical School Pain Curriculum.

Objective: To examine the immediate effects of a comprehensive pain course on medical students' pre-existing perceptions and attitudes toward pain patients and opioid management. Methods: First-year medical students at a major academic medical center enrolled in a required pre-clerkship pain course in June 2020 and completed pre- and post-course online surveys with Likert-scale questions about their attitudes toward pain management and opioid-related issues. Additionally, the surveys included a free-text question where the students listed the first five words that came to mind when hearing the word "opioids". These words were categorized as "professional" or "lay" words and further as having "positive", "negative", or "neutral" connotations. Data analyses included descriptive statistics, as well as non-parametric and parametric tests. Results: Fifty-four of the 119 students responded to pretest and posttest surveys and were included in paired analyses. There was a significant difference between the number of professional words used before (M=1.21, SD=0.97) and after the course (M=2.40 SD=1.33); t(52)=-6.39, P<0.001. Students also used more lay-positive words after the course (M=0.81, SD=0.63) than they used pre-course (M=0.23, SD=0.43); t(51)=-5.98, P<0.001. Students' post-course responses to several key Likert-scale questions showed significant shifts toward more positive attitudes about caring for patients with pain. For example, students acknowledged greater comfort in providing opioids for chronic pain (P<0.001) where appropriate, and enhanced interest in handling complex pain cases (P<0.001). Conclusion: Results showed that a comprehensive, multi-disciplinary pain course could greatly enhance first-year medical students' attitudes toward pain management, chronic pain patients, and the complex issues surrounding opioids.

Correlation Between Temperature Rise After Sympathetic Block and Pain Relief in Patients with Complex Regional Pain Syndrome.

OBJECTIVE: Determine the correlation between post-sympathetic block temperature change and immediate- and intermediate-term pain relief. DESIGN: Retrospective analysis. SETTING: Academic setting. SUBJECTS: Seventy-nine patients with complex regional pain syndrome who underwent sympathetic block. METHODS: Pre- and post-block temperatures in the affected extremity and pain scores immediately (based on 6-hour pain diary) after the block and at the intermediate-term 4- to 8-week follow-up were recorded. Post-block pain reductions of 30-49% and ≥50% were designated as partially sympathetically maintained pain and sympathetically maintained pain, respectively. A decrease in pain score ≥2 points lasting ≥4 weeks was considered a positive intermediate-term outcome for sympathetic block. RESULTS: A weak correlation was found between immediate-term pain relief and the extent of temperature rise for the cohort (R = 0.192, P = 0.043). Greater immediate-term pain reduction was reported among patients who experienced a temperature increase ≥7.5°C (mean 4.1; 95% confidence interval [CI]: 3.33 to 4.76) than among those who experienced a temperature increase <2°C (2.3; 95% CI: 1.36 to 3.31) or ≥2°C to <7.5°C (2.9; 95% CI: 1.8 to 3.9; P = 0.036). The correlations between temperature increase and intermediate-term pain score reduction at 4-8 weeks (R = 0.052, P = 0.329) and between immediate- and intermediate-term pain relief (R = 0.139, P = 0.119) were not statistically significant. CONCLUSIONS: A weak correlation was found for those who experienced greater temperature increases after the block to also experience greater immediate pain relief. Higher temperature increase cutoffs than are typically used might be necessary to determine whether a patient with complex regional pain syndrome has sympathetically maintained pain.

Mobilization Safety of Critically Ill Children.

BACKGROUND: Children in PICUs experience negative sequelae of immobility; however, interprofessional staff concerns about safety are a barrier to early mobilization. Our objective was to determine the safety profile of early mobilization in PICU patients. METHODS: We conducted a secondary analysis of a 2-day study focused on physical rehabilitation in 82 PICUs in 65 US hospitals. Patients who had ≥72-hour admissions and participated in a mobility event were included. The primary outcome was occurrence of a potential safety event during mobilizations. RESULTS: On 1433 patient days, 4658 mobility events occurred with a potential safety event rate of 4% (95% confidence interval [CI], 3.6%-4.7%). Most potential safety events were transient physiologic changes. Medical equipment dislodgement was rare (0.3%), with no falls or cardiac arrests. Potential safety event rates did not differ by patient age or sex. Patients had higher potential safety event rates if they screened positive for delirium (7.8%; adjusted odds ratio, 5.86; 95% CI, 2.17-15.86) or were not screened for delirium (4.7%; adjusted odds ratio, 3.98; 95% CI, 1.82-8.72). There were no differences in potential safety event rates by PICU intervention, including respiratory support or vasoactive support. CONCLUSIONS: Early PICU mobilization has a strong safety profile and medical equipment dislodgement is rare. No PICU interventions were associated with increased potential safety event rates. Delirium is associated with higher potential safety event rates. These findings highlight the need to improve provider education and confidence in mobilizing critically ill children.

Sleep in the Hospitalized Child: A Contemporary Review.

Acute illness and hospitalization introduce several risk factors for sleep disruption in children that can negatively affect recovery and healing and potentially compromise long-term cognition and executive function. The hospital setting is not optimized for pediatric sleep promotion, and many of the pharmacologic interventions intended to promote sleep in the hospital actually may have deleterious effects on sleep quality and quantity. To date, evidence to support pharmacologic sleep promotion in the pediatric inpatient setting is sparse. Therefore, nonpharmacologic interventions to optimize sleep-wake patterns are of highest yield in a vulnerable population of patients undergoing active neurocognitive development. In this review, we briefly examine what is known about healthy sleep in children and describe risk factors for sleep disturbances, available sleep measurement tools, and potential interventions for sleep promotion in the pediatric inpatient setting.

Changes in Pain Medicine Training Programs Associated With COVID-19: Survey Results.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic is a public health crisis of unprecedented proportions that has altered the practice of medicine. The pandemic has required pain clinics to transition from in-person visits to telemedicine, postpone procedures, and cancel face-to-face educational sessions. There are no data on how fellowship programs have adapted. METHODS: A 17-question survey was developed covering topics including changes in education, clinical care, and psychological stress due to the COVID pandemic. The initial survey was hosted by Qualtrics Inc and disseminated by the Association of Pain Program Directors on April 10, 2020, to program directors at Accreditation Council for Graduate Medical Education (ACGME)-accredited fellowships. Results are reported descriptively and stratified by COVID infection rate, which was calculated from Centers for Disease Control and Prevention data on state infections, and census data. RESULTS: Among 107 surveys distributed, 70 (65%) programs responded. Twenty-nine programs were located in states in the upper tertile for per capita infection rates, 17 in the middle third, and 23 in the lowest tertile. Nearly all programs (93%) reported a decreased workload, with 11 (16%) reporting a dramatic decrease (only urgent or emergent cases). Just more than half of programs had either already deployed (14%) or credentialed (39%) fellows to provide nonpain care. Higher state infection rates were significantly associated with reduced clinical demand (Rs = 0.31, 95% confidence interval [CI], 0.08-0.51; P = .011) and redeployment of fellows to nonpain areas (Rs = 0.30, 95% CI, 0.07-0.50; P = .013). Larger program size but not infection rate was associated with increased perceived anxiety level of trainees. CONCLUSIONS: We found a shift to online alternatives for clinical care and education, with correlations between per capita infection rates, and clinical care demands and redeployment, but not with overall trainee anxiety levels. It is likely that medicine in general, and pain medicine in particular, will change after COVID-19, with greater emphasis on telemedicine, virtual education, and greater national and international cooperation. Physicians should be prepared for these changes.

Tumor-infiltrating lymphocyte quantification stratifies early-stage human papillomavirus oropharynx cancer prognosis.

OBJECTIVES/HYPOTHESIS: To evaluate if a simple method for assessing tumor-infiltrating lymphocytes (TIL) in primary tumor specimens improves the prognostic value of the American Joint Committee on Cancer, 8th Edition (AJCC8) cancer staging system in human papillomavirus-positive oropharyngeal squamous cell carcinoma (HPV-OPC). STUDY DESIGN: Retrospective study. METHODS: In this study, TIL density was quantified on hematoxylin and eosin (H&E)-stained specimens from patients presenting to Johns Hopkins Hospital between 2009 and 2017 who underwent primary surgical therapy and had primary tumor specimens available for analysis. The prognostic effect of TIL density was evaluated by Kaplan-Meier method and Cox proportional hazards models considering recurrence-free survival (RFS) as the primary outcome. RESULTS: This study included 132 patients. Ninety-five percent were classified by clinical criteria with AJCC8 early-stage disease (stage I: 82%, stage II: 13%). After 84 months of follow-up, 15 recurrences were observed. Among clinically early-stage disease, TILhigh status was associated with improved RFS compared to TILlow (P = .002). Adjusted analysis showed TILhigh status was associated with 79% lower risk of recurrence than TILlow (adjusted hazard ratio [aHR]: 0.210, 95% confidence interval [CI]: 0.061-0.723). In clinical stage I disease, TILhigh status was associated with improved RFS compared to TILlow in both univariate and multivariate analyses (hazard ratio: 0.235, P = .021; aHR: 0.218; 95% CI: 0.058-0.822). TIL density similarly stratified risk in pathologically staged disease. CONCLUSIONS: In patients with AJCC8 stage I disease, low TIL density was associated with diminished RFS. Our data suggest that assessing TIL density on H&E-stained primary tumor specimens may enhance the prognostic resolution of the AJCC8 staging criteria for HPV-OPC.

Oropharyngeal cancer is no longer a disease of younger patients and the prognostic advantage of Human Papillomavirus is attenuated among older patients: Analysis of the National Cancer Database.

OBJECTIVES: HPV-positive oropharyngeal cancer (OPC) patients have been observed to be younger than patients with HPV-negative OPC at diagnosis. We evaluated recent trends in age at OPC diagnosis, and whether older age attenuates the survival benefit of HPV-positive tumor status. MATERIALS AND METHODS: Patients diagnosed with OPC from 2004 to 2014 represented in the National Cancer Database were included. HPV tumor status was available after 2010. Trends in age by calendar year were compared using linear regression. Overall survival was compared using Cox Proportional Hazards models. RESULTS: The mean age of OPC patients (N = 119,611) increased significantly from 2004 to 2014 (ß = 0.21 years of age per calendar year, 95% confidence interval [CI] = 0.19-0.23). The increase in age from 2010 to 2014 was similar for HPV-positive (N = 21,880; ß = 0.63, 95%CI = 0.53-0.72) and HPV-negative (N = 11,504; ß = 0.59, 95%CI = 0.45-0.74) patients. Between 2010 and 2014, the proportion of OPCs that were HPV-positive increased significantly for all age groups, including for patients ≥70 years old (from 45% to 60%, ptrend < 0.001). Although patients ≥70 years with HPV-OPC had improved survival compared to those with HPV-negative OPC (adjusted hazard ratio [aHR] = 0.65, 95%CI = 0.55-0.76), the survival benefit of HPV-positive tumor status was significantly attenuated compared to younger HPV-OPC patients (50-59 years: aHR = 0.45, 95%CI = 0.39-0.51; pinteraction < 0.001). CONCLUSION: The age at OPC diagnosis is increasing for both HPV-positive and HPV-negative patients, and a rising proportion of older patients have HPV-positive tumors. These findings dispel the notion that HPV-positive OPC is a disease of younger patients, identify a growing elderly population of HPV-positive OPC patients with reduced survival, and have implications for evolving treatment paradigms.
