Surgical Tray Optimization: a Quality Improvement Initiative that Reduces Operating Room Costs.

Surgical trays contain unused instruments which generate wasted resources from unnecessary reprocessing/replacement costs. We implemented a quality improvement initiative to optimize surgical trays for common otolaryngology procedures, and examined the impact on costs, operating room (OR) efficiency, and patient safety.We studied five common otolaryngology procedures over a 10-month period at a single community hospital. We compared pre- and post-intervention outcome measures including instrument utilization, tray set up time, tray rebuilding time, and balancing measures (operative time, instrument recall, patient safety). We estimated cost-savings from an institutional perspective over 1- and 10-year time horizons. Costs were expressed in 2017 Canadian dollars and modeled as a function of surgical volume, labor costs, instrument depreciation, and indirect costs.A total of 238 procedures by six surgeons were observed. At baseline, only 35% of instruments were utilized. We achieved an average instrument reduction of 26%, yielding 1-year cost savings of $9,010 CDN and 10-year cost savings of $69,576 CDN. Tray optimization reduced average OR tray setup time by 2.5 ± 0.4 min (p = 0.03) and average tray rebuilding time by 1.4 ± 0.2 min (p = 0.06). There was minimal impact on balancing measures such as OR time, stakeholder perception of patient safety and trainee education, and only a single case of instrument recall.Surgical tray optimization is a simple, effective, and scalable strategy for reducing costs and improving OR efficiency without compromising patient safety.

A cost-utility analysis comparing CT surveillance, PET-CT surveillance, and planned postradiation neck dissection for advanced nodal HPV-positive oropharyngeal cancer.

BACKGROUND: The cost utility of image-guided surveillance using computed tomography (CT) and positron emission tomography (PET)-CT to planned postradiation neck dissection (PRND) was compared for the management of advanced nodal human papillomavirus-positive oropharyngeal cancer following chemoradiation. METHODS: A universal payer perspective was adopted. A Markov model was designed to simulate four treatment approaches with 3-month cycles over a lifetime horizon: 1) CT surveillance, 2) standard PET-CT surveillance, 3) a novel PET-CT approach with repeat PET at 6 months postchemoradiation for equivocal responders, and 4) PRND. Parameters including probabilities of CT nodal progression/resolution, PET avidity, recurrence, and survival were obtained from the literature. Costs were reported in 2019 Canadian dollars and utilities were expressed in quality-adjusted life years (QALYs). Deterministic and probabilistic sensitivity analyses were performed to evaluate model uncertainty. RESULTS: PET-CT surveillance dominated CT surveillance and PRND in the base case scenario, and the novel PET-CT approach was the most cost-effective strategy across a wide range of variables tested in one-way sensitivity analysis. On probabilistic sensitivity analysis, novel PET-CT surveillance was the most cost-effective strategy in 78.1% of model iterations at a willingness-to-pay of $50,000/QALYs. Novel PET-CT surveillance resulted in a 49% lower rate of neck dissection compared with traditional PET-CT, and yielded an incremental benefit of 0.14 QALYs with average cost savings of $1309. CONCLUSIONS: Image-guided surveillance including PET-CT and CT are more cost effective than PRND. The novel PET-CT approach with repeat PET for equivocal responders was the dominant strategy and yielded both higher benefit and lower costs compared with standard PET-CT surveillance.

Cost-effectiveness of endoscopic endonasal vs transcranial approaches for olfactory groove meningioma.

BACKGROUND: Endoscopic endonasal approaches (EEAs) have been adopted as an alternative to standard transcranial approaches for olfactory groove meningiomas (OGMs). However, the relative cost-effectiveness remains controversial. METHODS: Cost-utility analysis from a societal perspective comparing EEA vs transcranial approaches for OGM was used in this study. Surgical treatment was modeled using decision analysis, and a Markov model was adopted over a 20-year horizon. Parameters were obtained from literature review. Costs were expressed in 2017 Canadian dollars. RESULTS: In the base case, EEA was cost-effective compared with transcranial surgery with an incremental cost-effectiveness ratio of $33 523 ($30 475 USD)/QALY. There was a 55% likelihood that EEA was cost-effective at a willingness-to-pay of $50 000/QALY. EEA remained cost-effective at a cerebrospinal fluid leak rate below 60%, gross total resection rate above 25%, and base cost less than $66 174 ($60 158 USD). CONCLUSION: EEA may be a cost-effective alternative to transcranial approaches for selected OGM.

Gentamicin Vestibulotoxicity: Further Insights From a Large Clinical Series.

OBJECTIVE: To review insights gained from a 21-year experience with gentamicin-induced vestibulotoxicity including differences in vestibulotoxicity between single daily dosing (SDD) and multiple daily dosing (MDD) regimens. STUDY DESIGN: Retrospective case series. SETTING: Tertiary care center. PATIENTS: Patients with gentamicin vestibulotoxicity referred to the Hertz Multidisciplinary Neurotology Clinic between January 1993 and September 2014. INTERVENTION: None. MAIN OUTCOME MEASURES: Spectrum of vestibular dysfunction measured using videonystagmography, vestibular evoked myogenic potentials, video head impulse testing, and magnetic scleral search coil testing. RESULTS: Of 53 patients with gentamicin-induced vestibulotoxicity, 24 received SDD and 29 received MDD treatment. The most common indications for treatment were sepsis, endocarditis, and osteomyelitis. Angular acceleration receptor function (semicircular canals) was more commonly affected than linear acceleration receptor function (otolithic organ of the saccule; 100% vs. 62%). A significant proportion of patients (53%) developed vestibulotoxicity in the absence of nephrotoxicity and 40% experienced vestibulotoxicity in a delayed fashion up to 10 days posttreatment cessation (mean 3.9 ±â€Š0.7). Therapeutic monitoring did not necessarily prevent delayed vestibulotoxicity. Nephrotoxicity was less common for SDD compared with MDD (60% vs. 35%, p = 0.01). However, the SDD group experienced vestibulotoxicity at a lower cumulative dose (6.3 vs. 7.0 g, p = 0.04) and shorter duration of therapy (20.7 vs 29.4 d, p = 0.02). CONCLUSIONS: Our study further highlights important insights regarding gentamicin-induced vestibulotoxicity. While SDD is associated with decreased risk for nephrotoxicity compared with MDD, it confers a higher risk for vestibulotoxicity.

Academic benchmarks for leaders in Otolaryngology - Head & Neck Surgery: a Canadian perspective.

BACKGROUND: The present study summarizes the demographics, subspecialty training, and academic productivity of contemporary leaders in Canadian Otolaryngology - Head & Neck Surgery (OHNS) training programs across Canada. METHODS: Demographic data regarding chairpersons (CPs) and program directors (PDs) were obtained from publicly-available faculty listings and online sources, and included employment institution, residency training, fellowship training status, gender, and years of post-graduate experience. Research productivity was measured using the h-index and number of publications, obtained from Scopus. Characteristics of CPs and PDs were compared using statistical analysis. RESULTS: Cross-sectional data was obtained from a total of 27 CPs and PDs from 13 accredited OHNS training programs across Canada active on July 1, 2019. All academic leaders completed at least 1 year of fellowship training. Head and neck oncology represented 77% of CPs and 59% of academic leaders overall, while pediatric otolaryngology represented 43% of PDs. Females represented 11% of academic leaders. There was a significant association between location of residency training and employment, with 56% (15/27) of physicians working where they had trained (p = 0.001, Fisher's exact test; φ = 2.63, p = 0.001). On average, individuals with a graduate (Master's) degree had a significantly higher H-index (17.7 vs 7.4, p = 0.001) and greater number of publications (106 vs. 52, p = 0.02). Compared to PDs, CPs had a significantly higher average h-index score (14.5 vs. 8.14, p = 0.04) and accrued more years of post-graduate experience (29.7 vs. 21.3 years, p = 0.008). There were no differences in the proportions of CPs and PDs with graduate degrees. There appeared to be a decline in research productivity beginning 3 years after academic appointment. CONCLUSIONS: This cross-sectional overview of academic leaders in Canadian OHNS programs demonstrates the following key findings: 1) all leaders completed fellowship training; 2) head and neck surgical oncology was the most common fellowship training subspecialty; 3) leaders were likely to be employed at the institution where they trained; 4) a Master's degree may be associated with increased research productivity; 5) there is a potential risk of decreased productivity after appointment to a leadership position; and 6) women are underrepresented in academic leadership roles.

Is Frailty Associated With Worse Outcomes After Head and Neck Surgery? A Narrative Review.

OBJECTIVE: Frailty has emerged as an important determinant of many health outcomes across various surgical specialties. We examined the published literature reporting on frailty as a predictor of perioperative outcomes in head and neck cancer (HNC) surgery. STUDY DESIGN: Narrative review with limited electronic database search and cross-referencing of included studies. METHODS: PubMed was searched from inception until June 2019 to capture studies evaluating an association between frailty and perioperative outcomes among patients undergoing HNC surgery. Primary outcomes included mortality and morbidity, whereas secondary outcomes included in-hospital cost, length of stay, readmission, and discharge disposition. RESULTS: We identified nine series examining frailty as a predictor of outcomes in HNC. The majority of studies (77%) identified patients using a large population-based database such as the National Surgical Quality Improvement Project or National Inpatient Sample. Frailty measures applied in the HNC surgery literature include the modified frailty index, Groningen Frailty Indicator, and John Hopkins Adjusted Clinical Groups frailty-defining diagnosis indicator. Most studies demonstrated a significant association between frailty and perioperative outcomes, including mortality, perioperative complications, and Clavien-Dindo grade IV complications. Furthermore, frailty was associated with greater length of hospital stay, readmission rate, and likelihood of discharge to short-term or skilled nursing facilities. CONCLUSION: The current literature demonstrates the utility of frailty as a predictor of perioperative mortality and morbidity. Further research is needed to develop frailty screening measures in order to risk-stratify patients and optimize modifiable factors preoperatively. Laryngoscope, 130:1436-1442, 2020.

Impact of Septal Deviation on Recurrent Chronic Rhinosinusitis after Primary Surgery: A Matched Case-Control Study.

OBJECTIVE: To evaluate the impact of untreated deviated nasal septum (DNS) on recalcitrant chronic rhinosinusitis (CRS) among patients undergoing revision endoscopic sinus surgery (ESS). STUDY DESIGN: Case-control study. SETTING: Tertiary academic center. SUBJECTS AND METHODS: We performed a retrospective review of 489 patients undergoing revision ESS for CRS at a tertiary academic center. Patients undergoing septoplasty were matched to nonseptoplasty controls based on age and sex. Preoperative Lund-Mackay score (LMS) was compared between cohorts. Linear regression was used to identify predictors of LMS and ostiomeatal complex (OMC) obstruction. RESULTS: Thirty-six matched pairs (72 patients) were selected for analysis: 36 undergoing septoplasty and revision ESS and 36 undergoing revision ESS alone. Compared with nonseptoplasty controls, the septoplasty group had a significantly higher average LMS (17.8 vs 14.6, P = .02) and a greater rate of OMC obstruction (89% vs 61%, P < .01). The septoplasty group also had significantly higher opacification scores in the maxillary (1.5 vs 1.2, P = .03) and posterior ethmoid (1.8 vs 1.4, P = .02) sinuses. On multivariable analysis, DNS was an independent predictor of LMS ( P = .02) and OMC obstruction ( P < .01). CONCLUSION: Untreated DNS is associated with radiographic markers of CRS severity among patients undergoing revision ESS and may contribute to the multifactorial pathogenesis of persistent CRS.

Impact of neoadjuvant radiation on margins for non-squamous cell carcinoma sinonasal malignancies.

OBJECTIVES/HYPOTHESIS: Treatment of non-squamous cell carcinoma sinonasal malignancies (NSCCSMs) typically involves surgery and radiotherapy (RT), but optimal sequencing remains controversial. STUDY DESIGN: Retrospective chart review. METHODS: Patients with NSCCSM treated with combined surgery and RT between 2000 and 2011 were identified. Margin control, overall survival, disease-free survival, local recurrence-free survival, and regional recurrence-free survival were compared between neoadjuvant and adjuvant RT groups. RESULTS: Eight-four patients were included (23 neoadjuvant and 61 adjuvant RT). A higher proportion of patients receiving neoadjuvant RT achieved negative/close resection margins compared to those receiving adjuvant RT (83% vs. 41%, P = .003). Multivariable analysis also showed that neoadjuvant RT was associated with an 81% decreased odds of positive margins odds ratio: 0.19, 95% confidence interval: 0.05-0.77, P = .02). CONCLUSIONS: Neoadjuvant RT may be associated with improved margin status among patients with NSCCSM treated with surgery and RT. Future prospective studies with larger, more homogeneous populations are needed to clarify optimal treatment strategies. LEVEL OF EVIDENCE: 4 Laryngoscope, 128:2796-2803, 2018.

Impact of Dural Resection on Sinonasal Malignancies with Skull Base Encroachment or Erosion.

Objectives (1) To determine the occult rate of dural invasion in patients with tumors extending to and/or eroding the bony anterior skull base but without evidence of dural invasion on preoperative imaging. (2) To determine the impact of dural resection and of skull base erosion on survival outcomes in this group of patients (without evidence of dural invasion upon preoperative imaging). Study Design Retrospective study. Setting Tertiary care academic center. Participants Patients with sinonasal malignancies with anterior skull base encroachment/erosion without dural invasion on preoperative imaging treated surgically. Main Outcome Measures (1) Histopathologic disease in the dura in patients who had dural resection and (2) Oncologic outcomes (5-year local recurrence, dural recurrence, disease-specific survival, and overall survival) in patients with and without dural resection, and patients with and without skull base erosion. Results Thirty-seven patients were included. The occult rate of dural invasion was 54%. Patients with dural resection had improved margin control versus those without dural resection (90% vs 56%, p = 0.02). Dural resection improved 5-year overall survival only in patients with esthesioneuroblastoma compared with bony skull base resection alone (100% vs 75%, p = 0.03). Patients with skull base erosion had reduced local control versus those without erosion (63% vs 93%, p = 0.047). Conclusion This study suggests a substantial rate of occult dural invasion despite no overt imaging findings. Dural resection may be associated with improved margin control, but no oncologic benefit except for esthesioneuroblastomas, although treatment heterogeneity and small sample size may limit conclusions.

Perioperative mortality rates in low-income and middle-income countries: a systematic review and meta-analysis.

INTRODUCTION: The Lancet Commission on Global Surgery proposed the perioperative mortality rate (POMR) as one of the six key indicators of the strength of a country's surgical system. Despite its widespread use in high-income settings, few studies have described procedure-specific POMR across low-income and middle-income countries (LMICs). We aimed to estimate POMR across a wide range of surgical procedures in LMICs. We also describe how POMR is defined and reported in the LMIC literature to provide recommendations for future monitoring in resource-constrained settings. METHODS: We did a systematic review of studies from LMICs published from 2009 to 2014 reporting POMR for any surgical procedure. We extracted select variables in duplicate from each included study and pooled estimates of POMR by type of procedure using random-effects meta-analysis of proportions and the Freeman-Tukey double arcsine transformation to stabilise variances. RESULTS: We included 985 studies conducted across 83 LMICs, covering 191 types of surgical procedures performed on 1 020 869 patients. Pooled POMR ranged from less than 0.1% for appendectomy, cholecystectomy and caesarean delivery to 20%-27% for typhoid intestinal perforation, intracranial haemorrhage and operative head injury. We found no consistent associations between procedure-specific POMR and Human Development Index (HDI) or income-group apart from emergency peripartum hysterectomy POMR, which appeared higher in low-income countries. Inpatient mortality was the most commonly used definition, though only 46.2% of studies explicitly defined the time frame during which deaths accrued. CONCLUSIONS: Efforts to improve access to surgical care in LMICs should be accompanied by investment in improving the quality and safety of care. To improve the usefulness of POMR as a safety benchmark, standard reporting items should be included with any POMR estimate. Choosing a basket of procedures for which POMR is tracked may offer institutions and countries the standardisation required to meaningfully compare surgical outcomes across contexts and improve population health outcomes.

Costs and Perioperative Outcomes Associated with Open versus Endoscopic Resection of Sinonasal Malignancies with Skull Base Involvement.

Objective To compare financial and perioperative outcomes between endoscopic and open surgical approaches in the surgical management of sinonasal malignancies. Design Retrospective chart review. Setting Tertiary care hospital. Participants Patients undergoing surgical resection of a sinonasal malignancy from January 2000 to December 2014. Main Outcome Measures In-hospital costs, complications, and length of stay (LOS). Results Of 106 patients, 91 received open surgery (19 free flap and 72 non-free flap) and 15 were treated with purely endoscopic approaches. Free flaps had a significantly higher average cost, operative time, and LOS compared to both non-free flap ( p < 0.001, < 0.001, and < 0.01) and endoscopic ( p = 0.01, 0.04, and < 0.01) groups. There were no significant differences in average costs between endoscopic and non-free flap groups ($19,157 vs. $14,806, p = 0.20) or LOS (5.7 vs. 6.4 days, p = 0.72). Compared with the non-free flap group, the endoscopic group had a longer average operative time (8.3 vs. 5.5 hours, p < 0.01) and higher rates of cerebrospinal fluid (CSF) leak (13 vs. 0%, p = 0.01) and intensive care unit (ICU) admission (80 vs. 36%, p < 0.01). Surgical approach (open vs. endoscopic) was not a significant predictor of any financial or perioperative outcome on multivariable analysis. Conclusion Hospital costs are comparable between endoscopic and open approaches when no free tissue reconstruction is required. Longer operative times, higher CSF leak rates, and our institutional protocol necessitating ICU admission for endoscopic cases may account for the failure to demonstrate cost savings with endoscopic surgery.

Esterified Trehalose Analogues Protect Mammalian Cells from Heat Shock.

Trehalose is a disaccharide produced by many organisms to better enable them to survive environmental stresses, including heat, cold, desiccation, and reactive oxygen species. Mammalian cells do not naturally biosynthesize trehalose; however, when introduced into mammalian cells, trehalose provides protection from damage associated with freezing and drying. One of the major difficulties in using trehalose as a cellular protectant for mammalian cells is the delivery of this disaccharide into the intracellular environment; mammalian cell membranes are impermeable to the hydrophilic sugar trehalose. A panel of cell-permeable trehalose analogues, in which the hydrophilic hydroxyl groups of trehalose are masked as esters, have been synthesized and the ability of these analogues to load trehalose into mammalian cells has been evaluated. Two of these analogues deliver millimolar concentrations of free trehalose into a variety of mammalian cells. Critically, Jurkat cells incubated with these analogues show improved survival after heat shock, relative to untreated Jurkat cells. The method reported herein thus paves the way for the use of esterified analogues of trehalose as a facile means to deliver high concentrations of trehalose into mammalian cells for use as a cellular protectant.

Predictors of falls and mortality among elderly adults with traumatic brain injury: A nationwide, population-based study.

BACKGROUND: Elderly adults are at particular risk of sustaining a traumatic brain injury (TBI), and tend to suffer worse outcomes compared to other age groups. Falls are the leading cause of TBI among the elderly. METHODS: We examined nationwide trends in TBI hospitalizations among elderly adults (ages 65 and older) between April 2006 and March 2011 using a population-based database that is mandatory for all hospitals in Canada. Trends in admission rates were analyzed using linear regression. Predictors of falls and in-hospital mortality were identified using logistic regression. RESULTS: Between 2006 and 2011, there were 43,823 TBI hospitalizations resulting in 6,939 deaths among elderly adults in Canada. Over the five-year study period, the overall rate of TBI admissions increased by an average of 6% per year from 173.2 to 214.7 per 100,000, while the rate of fall-related TBI increased by 7% annually from 138.6 to 179.2 per 100,000. There were significant trends towards increasing age and comorbidity level (p<0.001 and p = 0.002). Advanced age, comorbidity, and injury severity were independent predictors of both TBI-related falls and mortality on multivariate analysis. CONCLUSION: Prevention efforts should be targeted towards vulnerable demographics including the "older old" (ages 85 and older) and those with multiple medical comorbidities. Additionally, hospitals and long-term care facilities should be prepared to manage the burgeoning population of older patients with more complex comorbidities.

A program evaluation of Kids2Hear, a student-run hearing screening program for school children.

BACKGROUND: Hearing deficits in children are demonstrably negatively associated with language acquisition and cognition. Although universal neonatal hearing screening exists, it is not offered equally across Canada. Additionally, children emigrating from other countries are often not assessed. The objective of this study is to evaluate Kids2Hear, a free hearing screening program run by medical students at elementary schools, and to determine the rate of hearing deficits that were identified and referred for evaluation. METHODS: Retrospective analysis of screening program data from 228 participants seen at three inner-city elementary schools over six months. RESULTS: In our sample, the mean age was 5.8 ± 1.0 years with 48 % males. Approximately 21 participants (9.3 %) were screened positive for a hearing deficit and required referral for supplementary audiological evaluation. About 44 participants (19.3 %) were referred to a family physician for otoscopic abnormalities. Females were significantly more likely to be identified for both hearing deficits and otoscopic abnormalities. CONCLUSIONS: Hearing deficits and otoscopic abnormalities are common among young children. Female children may be at higher risk for developing hearing issues or otoscopic abnormalities compared to males. Additional research is needed to determine the effectiveness of hearing screening programs.

The role of transoral robotic surgery, transoral laser microsurgery, and lingual tonsillectomy in the identification of head and neck squamous cell carcinoma of unknown primary origin: a systematic review.

BACKGROUND: Squamous cell carcinoma of the head and neck can present as a cervical metastasis from an unknown primary site. Recently, transoral robotic surgery (TORS) and transoral laser microsurgery (TLM) have been incorporated in the workup of unknown primary tumors. METHODS: We searched MEDLINE, EMBASE, Cochrane, and CINAHL from inception to June 2015 for all English-language studies that utilized TORS, TLM, or lingual tonsillectomy in the approach to an unknown primary. RESULTS: Of 217 identified studies, eight were reviewed. TORS/TLM identified the primary tumor in 111/139 (80 %) patients overall, and 36/54 (67 %) patients with no remarkable findings following physical exam, radiologic imaging, and panendoscopy with directed biopsies. Lingual tonsillectomy identified the primary tumor in 18/25 (72 %) patients with no findings. Hemorrhage (5 %) was the most common perioperative complication. CONCLUSION: Lingual tonsillectomy using new approaches such as TORS/TLM may improve the identification of occult primary tumors.

The impact of psychosocial intervention on survival in cancer: a meta-analysis.

BACKGROUND: The impact of psychosocial interventions on survival remains controversial in patients with cancer. A meta-analysis of the recent literature was conducted to evaluate the potential survival benefit associated with psychosocial interventions for cancer patients. METHODS: MEDLINE, EMBASE, and Cochrane Central were searched from January 2004 to May 2015 for all randomized controlled trials (RCTs) that compared survival outcomes between cancer patients receiving a psychosocial intervention and those receiving other, or no interventions. Endpoints included one-, two-, and four-year overall survival. Subgroup analyses were performed to compare group-versus individually-delivered interventions, and to assess breast cancer-only trials. RESULTS: Of 5,080 identified articles, thirteen trials were included for analysis. There was a significant survival benefit for the intervention group at one year [risk ratio (RR) =0.82; 95% confidence interval (CI), 0.67-1.00; P=0.04] and two years (RR =0.86; 95% CI, 0.78-0.95; P=0.003). However, no significant difference was detected at four years (RR =0.94; 95% CI, 0.85-1.04; P=0.24). Among patients with breast cancer, there was a significant survival benefit of psychosocial interventions at one year (RR =0.59; 95% CI, 0.42-0.82; P=0.002), but no difference at two years (RR =0.82; 95% CI, 0.67-1.02; P=0.07) or four years (RR =0.95; 95% CI, 0.73-1.23; P=0.68). Group-delivered interventions had a significant survival benefit favouring the intervention group at one year (RR =0.57; 95% CI, 0.41-0.79; P=0.0008), but no difference at two years (RR =0.84; 95% CI, 0.68-1.02; P=0.08) or four years (RR =0.94; 95% CI, 0.75-1.20; P=0.64). Individually-delivered interventions had no significant survival benefit at one year (RR =0.92; 95% CI, 0.79-1.08; P=0.32), two years (RR =0.87; 95% CI, 0.75-1.00; P=0.05), or four years (RR =0.93; 95% CI, 0.84-1.04; P=0.21). CONCLUSIONS: For the main analysis and group-delivered treatments, psychosocial interventions demonstrated only short-term improvements in survival. Individually-delivered interventions failed to show any survival benefit. Future studies with longer follow-up are warranted to investigate long-term survival outcomes.

Comparison of the EORTC STO-22 and the FACT-Ga quality of life questionnaires for patients with gastric cancer.

This review compares the development, characteristics, validity, and reliability of two well-known quality of life (QOL) assessment tools used in patients with gastric cancer: the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Stomach (EORTC QLQ-STO22) and the Functional Assessment of Cancer Therapy-Gastric (FACT-Ga). A literature search was conducted using MEDLINE, EMBASE, and Cochrane CENTRAL (inception to April 2015) to identify studies that discussed the development, characteristics, validity and reliability of the EORTC QLQ-STO22 or the FACT-Ga. The QLQ-STO22 was developed with collaboration with patients, healthcare professionals and literature review and was mainly field tested in European countries. Conversely, items on the FACT-Ga were generated from interviews with patients and healthcare professionals concurrently in North America and Asia. While both modules involve a 7-day recall period and use Likert scales, the QLQ-STO22 and FACT-Ga differ in terms of QOL domain focus, quantity and presentation of items, response options, and scoring. However, both tools show good internal consistency, test-retest reliability, sensitivity to change and construct validity. In addition, both questionnaires have been internationally validated within a large sample of patients undergoing a variety of treatments, thus demonstrating their cross-cultural applicability. The EORTC QLQ-STO22 and FACT-Ga are both valid and reliable tools with unique strengths and weaknesses. Selection between instruments should consider specific patient characteristics and goals of the study.

Health & Economic Burden of Traumatic Brain Injury in the Emergency Department.

OBJECTIVE: To evaluate epidemiological patterns and lifetime costs of traumatic brain injury (TBI) identified in the emergency department (ED) within a publicly insured population in Ontario, Canada, in 2009. METHODS: A nationally representative, population-based database was used to identify TBI cases presenting to Ontario EDs between April 2009 and March 2010. We calculated unit costs for medical treatment and productivity loss, and multiplied these by corresponding incidence estimates to determine the lifetime costs of identified TBI cases across age group, sex, and mechanism of injury. RESULTS: In 2009, there were more than 133,000 ED visits for TBI in Ontario, resulting in a conservative estimate of $945 million in lifetime costs. Lifetime cost estimates ranged from $279 million to $1.22 billion depending on the diagnostic criteria used to define TBI. Peak rates of TBI occurred among young children (ages 0-4 year) and the elderly (ages 85+ years). Males experienced a 53% greater rate of TBI and incurred two-fold higher costs compared with females. Falls, sports/bicyclist-related injuries, and motor vehicle crashes represented 47%, 12%, and 10% of TBI presenting to ED, respectively, and accounted for a significant proportion of costs. CONCLUSIONS: This study revealed an enormous health and economic burden associated with TBI identified in the ED setting. Our findings underscore the importance of ongoing surveillance and prevention efforts targeted to vulnerable populations. More research is needed to fully appreciate the burden of TBI across a variety of health care settings.

Epidemiological Trends of Traumatic Brain Injury Identified in the Emergency Department in a Publicly-Insured Population, 2002-2010.

OBJECTIVES: To examine epidemiological trends of Traumatic Brain Injury (TBI) treated in the Emergency Department (ED), identify demographic groups at risk of TBI, and determine the factors associated with hospitalization following an ED visit for TBI. METHODS: A province-wide database was used to identify all ED visits for TBI in Ontario, Canada between April 2002 and March 2010. Trends were analyzed using linear regression, and predictors of hospital admission were evaluated using logistic regression. RESULTS: There were 986,194 ED visits for TBI over the eight-year study period, resulting in 49,290 hospitalizations and 1,072 deaths. The age- and sex-adjusted rate of TBI decreased by 3%, from 1,013.9 per 100,000 (95% CI 1,008.3-1,010.6) to 979.1 per 100,000 (95% CI 973.7-984.4; p = 0.11). We found trends towards increasing age, comorbidity level, length of stay, and ambulatory transport use. Children and young adults (ages 5-24) sustained peak rates of motor vehicle crash (MVC) and bicyclist-related TBI, but also experienced the greatest decline in these rates (p = 0.003 and p = 0.005). In contrast, peak rates of fall-related TBI occurred among the youngest (ages 0-4) and oldest (ages 85+) segments of the population, but rates remained stable over time (p = 0.52 and 0.54). The 5-24 age group also sustained the highest rates of sports-related TBI but rates remained stable (p = 0.80). On multivariate analysis, the odds of hospital admission decreased by 1% for each year over the study period (OR = 0.991, 95% CI = 0.987-0.995). Increasing age and comorbidity, male sex, and ambulatory transport were significant predictors of hospital admission. CONCLUSIONS: ED visits for TBI are involving older populations with increasingly complex comorbidities. While TBI rates are either stable or declining among vulnerable groups such as young drivers, youth athletes, and the elderly, these populations remain key targets for focused injury prevention and surveillance. Clinicians in the ED setting should be cognizant of factors associated with hospitalization following TBI. LEVEL OF EVIDENCE: III. STUDY DESIGN: Cross-sectional.

Comparison of outcomes for open versus endoscopic approaches for olfactory neuroblastoma: A systematic review and individual participant data meta-analysis.

BACKGROUND: Endoscopic approaches have been adopted as an alternative to craniofacial resection in the surgical management of olfactory neuroblastoma. METHODS: We conducted a systematic review and meta-analysis using MEDLINE, EMBASE, Cochrane, and CINAHL (2000-2014) to compare outcomes for open versus endoscopic approaches. RESULTS: Thirty-six studies containing 609 patients were included. Meta-analysis of (a) all patients, (b) Kadish C/D only, and (c) Hyams III/IV only, failed to show a difference in locoregional control and metastasis-free survival between approaches. However, endoscopic approaches were associated with improved overall survival (OS) for all 3 groups (p = .001, .04, and .001, respectively), and higher disease-specific survival (DSS) for all patients (p = .004) and Hyams III/IV only (p = .002). CONCLUSION: The current study suggests that endoscopic approaches have comparable control rates to open approaches for olfactory neuroblastoma. © 2015 Wiley Periodicals, Inc.
