Importance Assessment of physical frailty in older trauma patients admitted to the intensive care unit is often not feasible using traditional frailty assessment instruments. The use of opportunistic computed tomography (CT) scans to assess sarcopenia and osteopenia as indicators of underlying frailty may provide complementary prognostic information on long-term outcomes. Objective To determine whether sarcopenia and/or osteopenia are associated with 1-year mortality in an older trauma patient population. Design, Setting, and Participants A retrospective cohort constructed from a state trauma registry was linked to the statewide death registry and Comprehensive Hospital Abstract Reporting System for readmission data analyses. Admission abdominopelvic CT scans from patients 65 years and older admitted to the intensive care unit of a single level I trauma center between January 2011 and May 2014 were analyzed to identify patients with sarcopenia and/or osteopenia. Patients with a head Injury Severity Score of 3 or greater, an out-of-state address, or inadequate CT imaging or who died within 24 hours of admission were excluded. Exposures Sarcopenia and/or osteopenia, assessed via total cross-sectional muscle area and bone density at the L3 vertebral level, compared with a group with no sarcopenia or osteopenia. Main Outcomes and Measures One-year all-cause mortality. Secondary outcomes included 30-day all-cause mortality, 30-day readmission, hospital length of stay, hospital cost, and discharge disposition. Results Of the 450 patients included in the study, 269 (59.8%) were male and 394 (87.6%) were white. The cohort was split into 4 groups: 74 were retrospectively diagnosed with both sarcopenia and osteopenia, 167 with sarcopenia only, 48 with osteopenia only, and 161 with no radiologic indicators. Among the 408 who survived to discharge, sarcopenia and osteopenia were associated with higher risks of 1-year mortality alone and in combination. After adjustment, the hazard ratio was 9.4 (95% CI, 1.2-75.4; P = .03) for sarcopenia and osteopenia, 10.3 (95% CI, 1.3-78.8; P = .03) for sarcopenia, and 11.9 (95% CI, 1.3-107.4; P = .03) for osteopenia. Conclusions and Relevance More than half of older trauma patients in this study had sarcopenia, osteopenia, or both. Each factor was independently associated with increased 1-year mortality. Given the prevalent use of abdominopelvic CT in trauma centers, opportunistic screening for radiologic indicators of frailty provides an additional tool for early identification of older trauma patients at high risk for poor outcomes, with the potential for targeted interventions.

Objective Neuroendocrine tumors of the lung are currently staged with the 7th edition TNM non–small cell lung cancer staging system. This decision, based on data analysis without data on histology or disease‐specific survival, makes its applicability limited. This study proposes a specific staging system for these tumors. Methods We retrospectively analyzed 510 consecutive patients (female/male, 313/197; median age, 61 years; interquartile range, 51‐70) undergoing lung resection for a primary neuroendocrine tumor between 2000 and 2015 in 8 centers. Multivariable analysis was performed using a Cox proportional hazard model to identify factors associated with disease‐specific survival. A new staging system was proposed on the basis of the results of this analysis. Kaplan–Meier disease‐specific survival was analyzed by stage using the proposed and the 7th TNM staging system. Results Follow‐up was completed in 490 of 510 patients at a median of 51 months (interquartile range, 18‐99). Histology (G1‐typical carcinoid vs G2‐atypical carcinoid vs G3‐large‐cell neuroendocrine carcinoma) and pT were independently associated with survival, but pN was not. After regrouping histology and pT, we proposed the following staging system: IA (pT1‐2G1), IB (pT3G1, pT1G2), IIA (pT4G1, pT2‐3G2, pT1G3), IIB (pT4G2, pT2‐3G3), and III (pT4G3). The 5‐year survivals were 97.9%, 81.0%, 69.1%, 51.8%, and 0%, respectively. By using the 7th TNM, 5‐year survivals were 95.0%, 92.3%, 67.7%, 70.9%, and 65.1% for stage IA, IB, IIA, IIB, and III, respectively. Conclusions Incorporating histology and regrouping tumor stage create a unique neuroendocrine tumor staging system that seems to predict survival better than the 7th TNM classification.

BACKGROUND Older patients have an increased incidence of paraesophageal hernia (PEH) and can be denied surgical assessment due to the perception of increased complications and mortality. This study examines the influence of age and comorbidities on early complications and other short-term outcomes of PEH repair. METHODS From 2000 to 2016, data of surgically treated patients with PEH were prospectively recorded in an Institutional Review Board-approved database. Only patients whose hernia involved over 50% of the stomach were included. Patients were stratified by age (<70, 70 to 79, ≥80 years of age) and compared in univariate and multivariate analyses. RESULTS Overall, 524 patients underwent surgical PEH repair (<70: 261 [50%]; 70 to 79: 163 [31%]; ≥80: 100 [19%]). Patients greater than or equal to 80 years of age had higher American Society of Anesthesiologists class, more comorbidities, larger hernias, and higher incidences of type IV PEH and acute presentation. Patients greater than or equal to 80 years of age had more postoperative complications, but not higher grade complications (Clavien-Dindo grade ≥IIIa). Median length of stay was 1 day longer for patients greater than or equal to 80 years of age (5 days versus 4 days for patients <70 and 70 to 79 years of age, respectively). Objective, radiologic hernia recurrence at 4.3 months postoperation was 17.3% and was not increased in the greater than or equal to 80 years of age group. After adjustment for comorbidities and other factors, age greater than or equal to 80 years was not a significant factor in predicting severe complications, readmission within 30 days, or early recurrence. CONCLUSIONS PEH repair is safe in physiologically stable patients, irrespective of age. Incidence of complications is higher in older patients, but complication severity and mortality are similar to those of younger patients. Patients with giant PEH should be given the opportunity to review treatments options with an experienced surgeon.

OBJECTIVE The purpose of this study is to develop and generate validity evidence for an instrument to measure social capital in residents. DESIGN Mixed-methods, phased approach utilizing a modified Delphi technique, focus groups, and cognitive interviews. SETTING Four residency training institutions in Washington state between February 2016 and March 2017. PARTICIPANTS General surgery, anesthesia, and internal medicine residents ranging from PGY-1 to PGY-6. RESULTS The initial resident-focused instrument underwent revision via Delphi process with 6 experts; 100% expert consensus was achieved after 4 cycles. Three focus groups were conducted with 19 total residents. Focus groups identified 6 of 11 instrument items with mean quality ratings ≤4.0 on a 1-5 scale. The composite instrument rating of the draft version was 4.1 ± 0.5. After refining the instrument, cognitive interviews with the final version were completed with 22 residents. All items in the final version had quality ratings >4.0; the composite instrument rating was 4.8 ± 0.1. CONCLUSIONS Social capital may be an important factor in resident wellness as residents rely upon each other and external social support to withstand fatigue, burnout, and other negative sequelae of rigorous training. This instrument for assessment of social capital in residents may provide an avenue for data collection and potentially, identification of residents at-risk for wellness degradation.

Background: Frailty is linked to poor outcomes in older patients. We prospectively compared the utility of the picture‐based Clinical Frailty Scale (CFS9), clinical assessments, and ultrasound muscle measurements against the reference FRAIL scale in older adult trauma patients in the emergency department (ED). Methods: We recruited a convenience sample of adults 65 yrs. or older with blunt trauma and injury severity scores <9. We queried subjects (or surrogates) on the FRAIL scale, and compared this to: physician‐based and subject/surrogate‐based CFS9; mid‐upper arm circumference (MUAC) and grip strength; and ultrasound (US) measures of muscle thickness (limbs and abdominal wall). We derived optimal diagnostic thresholds and calculated performance metrics for each comparison using sensitivity, specificity, predictive values, and area under receiver operating characteristic curves (AUROC). Results: Fifteen of 65 patients were frail by FRAIL scale (23%). CFS9 performed well when assessed by subject/surrogate (AUROC 0.91 [95% CI 0.84–0.98] or physician (AUROC 0.77 [95% CI 0.63–0.91]. Optimal thresholds for both physician and subject/surrogate were CFS9 of 4 or greater. If both physician and subject/surrogate provided scores <4, sensitivity and negative predictive value were 90.0% (54.1–99.5%) and 95.0% (73.1–99.7%). Grip strength and MUAC were not predictors. US measures that combined biceps and quadriceps thickness showed an AUROC of 0.75 compared to the reference standard. Conclusion: The ED needs rapid, validated tools to screen for frailty. The CFS9 has excellent negative predictive value in ruling out frailty. Ultrasound of combined biceps and quadriceps has modest concordance as an alternative in trauma patients who cannot provide a history.

OBJECTIVES The clinical utility of fluorodeoxyglucose-positron emission tomography (FDG-PET) and somatostatin receptor scintigraphy (SRS) in pulmonary carcinoids staging is unclear. This study aims to determine the role of FDG-PET and SRS in detecting hilar-mediastinal lymph node metastasis from these tumours. METHODS We retrospectively collected the data of 380 patients who underwent lung resection for primary pulmonary carcinoid in seven centres between 2000 and 2015. Patients without nodal sampling ( n  = 78) were excluded. In 302 patients [35% men, median age 58 (interquartile range 47-68) years] the results of preoperative computed tomography (CT) scan, FDG-PET and SRS were analysed and compared to the pathological findings after resection to determine the respective utility of these two nuclear tests. RESULTS The sensitivity, specificity and negative predictive value in detecting N1 and N2 disease were respectively 33% and 46%, 93% and 90%, 88% and 95% for computed-tomography-scan, 38% and 60%, 93% and 95%, 88% and 95% for FDG-PET, 22% and 33%, 95% and 98%, 84% and 87% for SRS. The diagnostic accuracy for N1 and N2 disease of CT scan was not significantly different from that of FDG-PET ( P  =   1.0 and P  =   0.37 for N1 and N2 disease respectively) and of SRS ( P  =   0.47 and P  =   0.35 for N1 and N2 disease respectively). The sensitivity and specificity of these imaging tests were also similar when analysed by typical vs atypical histology. CONCLUSIONS CT scan, FDG-PET and SRS showed similar performance in terms of nodal staging for pulmonary carcinoid. These findings suggest that additional nuclear imaging beyond CT scan is not required as long as a lymphadenectomy or nodal sampling is completed at resection.

Background Older adults are susceptible to adverse effects from opioids, nonsteroidal anti-inflammatory drugs (NSAIDs), and benzodiazepines (BZDs). We investigated factors associated with the administration of elevated doses of these medications of interest to older adults (≥65 years old) in the emergency department (ED). Patients and methods ED records were queried for the administration of medications of interest to older adults at two academic medical center EDs over a 6-month period. Frequency of recommended versus elevated (“High doses” were defined as doses that ranged between 1.5 and 3 times higher than the recommended starting doses; “very high doses” were defined as higher than high doses) starting doses of medications, as determined by geriatric pharmacy/medicine guidelines and expert consensus, was compared by age groups (65–69, 70–74, 75–79, 80–84, and ≥85 years), gender, and hospital. Results There were 17896 visits representing 11374 unique patients >65 years of age (55.3% men, 44.7% women). A total of 3394 doses of medications of interest including 1678 high doses and 684 very high doses were administered to 1364 different patients. Administration of elevated doses of medications was more common than that of recommended doses. Focusing on opioids and BZDs, the 65–69-year age group was much more likely to receive very high doses (1481 and 412 doses, respectively) than the ≥85-year age groups (relative risk [RR] 5.52, 95% CI 2.56–11.90), mainly reflecting elevated opioid dosing (RR 8.28, 95% CI 3.69–18.57). Men were more likely than women to receive very high doses (RR 1.47, 95% CI 1.26–1.72), primarily due to BZDs (RR 2.12, 95% CI 2.07–2.16). Conclusion Administration of elevated doses of opioids and BZDs in the older population occurs frequently in the ED, especially to the 65–69-year age group and men. Further attention to potentially unsafe dosing of high-risk medications to older adults in the ED is warranted.

Assessment of Osteoporosis in Injured Older Women Admitted to a Safety-Net Level One Trauma Center: A Unique Opportunity to Fulfill an Unmet Need

Elisabeth S. Young; May J. Reed; Tam N. Pham; Joel A. Gross; Lisa A. Taitsman; Stephen J. Kaplan

Background Older trauma patients often undergo computed tomography (CT) as part of the initial work-up. CT imaging can also be used opportunistically to measure bone density and assess osteoporosis. Methods In this retrospective cohort study, osteoporosis was ascertained from admission CT scans in women aged ≥65 admitted to the ICU for traumatic injury during a 3-year period at a single, safety-net, level 1 trauma center. Osteoporosis was defined by established CT-based criteria of average L1 vertebral body Hounsfield units <110. Evidence of diagnosis and/or treatment of osteoporosis was the primary outcome. Results The study cohort consisted of 215 women over a 3-year study period, of which 101 (47%) had evidence of osteoporosis by CT scan criteria. There were no differences in injury severity score, hospital length of stay, cost, or discharge disposition between groups with and without evidence of osteoporosis. Only 55 (59%) of the 94 patients with osteoporosis who survived to discharge had a documented osteoporosis diagnosis and/or corresponding evaluation/treatment plan. Conclusion Nearly half of older women admitted with traumatic injuries had underlying osteoporosis, but 41% had neither clinical recognition of this finding nor a treatment plan for osteoporosis. Admission for traumatic injury is an opportunity to assess osteoporosis, initiate appropriate intervention, and coordinate follow-up care. Trauma and acute care teams should consider assessment of osteoporosis in women who undergo CT imaging and provide a bridge to outpatient services.

Chris W. Piercecchi; Julio C. Vasquez; Stephen J. Kaplan; Mónica L. Mispireta; Jacob DeLaRosa

ABSTRACT Objective: Apathy and depression are common in older adult patients following open-heart surgery and contribute to delayed early mobility. The stimulant methylphenidate has not been widely studied in the older adult population. The aim of this study was to investigate differences in short-term outcomes between older adults who received methylphenidate following coronary artery bypass (CABG).Methods: In this retrospective cohort study, patients who underwent isolated CABG at a single community hospital were reviewed. All patients ≥70 years old were included. Groups were defined by whether or not they received postoperative methylphenidate (PM). Univariate and multivariate analysis was conducted. A generalized linear model predicting hospital length of stay (LOS) was constructed.Results: Of the 150 patients reviewed, 50 were included. Median age was 75.5 years (IQR 72–79). Seven patients were women. Twenty-seven patients received PM; 23 patients did not (NPM). Both groups had similar baseline and clinical characteristics. PM had shorter LOS (4 [3–5] days vs. 6 [4–7] days, p < 0.001). The association of methylphenidate with shorter LOS remained significant in multivariate analysis (IRR 0.74 [95% CI 0.62–0.87], p = 0.001). Mortality at 30-days was zero in both groups.Conclusions: PM following CABG may be associated with shorter LOS in the older adult population.
