Shifting Perspectives: Equal Blunt Cerebrovascular Risk in Low-Versus High-Energy Cervical Fracture.

INTRODUCTION: Clinical implications of screening for blunt cerebrovascular injury (BCVI) after low-energy mechanisms of injury (LEMI) remain unclear. We assessed BCVI incidence and outcomes in LEMI versus high-energy mechanisms of injury (HEMI) patients. METHODS: In this retrospective cohort study, blunt trauma adults admitted between July 2015 and June 2021 with cervical spine fractures, excluding single spinous process, osteophyte, and chronic fractures were included. Demographics, comorbidities, injuries, screening and treatment data, iatrogenic complications, and mortality were collected. Our primary end point was to compare BCVI rates between LEMI and HEMI patients. RESULTS: Eight hundred sixty patients (78%) were screened for BCVI; 120 were positive for BCVI. LEMI and HEMI groups presented similar BCVI rates (12.6% versus 14.4%; P = 0.640). Compared to HEMI patients (n = 95), LEMI patients (n = 25) were significantly older (79 ± 14.9 versus 54.3 ± 17.4, P < 0.001), more likely to be on anticoagulants before admission (64% versus 23.2%, P < 0.001), and less severely injured (LEMI injury severity score 10.9 ± 6.6 versus HEMI injury severity score 18.7 ± 11.4, P = 0.001). All but one LEMI and 90.5% of the HEMI patients had vertebral artery injuries with no significant difference in BCVI grades. One HEMI patient developed acute kidney injury because of BCVI screening. Eleven HEMI patients developed BCVI-related stroke with two related mortalities. One LEMI patient died of a BCVI-related stroke. CONCLUSIONS: BCVI rates were similar between HEMI and LEMI groups when screening based on cervical spine fractures. The LEMI group exhibited no screening or treatment complications, suggesting that benefits may outweigh the risks of screening and potential bleeding complications from treatment.

Exploring Outcomes Related to Residential Determinants in Acute Mesenteric Ischemia Patients.

INTRODUCTION: To access the relationship between residential status and outcomes in surgical acute mesenteric ischemia (AMI) patients. METHODS: Retrospective chart review of 153 AMI patients admitted to our institution between 2007 and 2021. Residential median income and Rural-Urban Commuting Area (RUCA) code were used as residential proxies. RESULTS: Being of the female sex (odds ratio [OR] = 3.116 [1.276-7.609] P = 0.013) and having a vascular intervention performed (OR = 2.927 [1.087-7.883] P = 0.034) were both associated with a threefold increase in the risk of mortality. Increased age (OR = 1.037 [1.002-1.073] P = 0.039), elevated blood urea nitrogen (OR = 1.032 [1.012-1.051] P = 0.001), and living in higher residential income area (OR = 1.049 [1.009-1.091] P = 0.017) had a small, but statistically significant, increased risk of mortality. Patients in higher median income areas were less likely to undergo colonic resection (OR = 0.953 [0.911-0.997] P = 0.038) and tended to have a lower likelihood of receiving an ostomy (OR = 0.963 [0.927-1] P = 0.051). Being from urban or rural areas was not associated with mortality (OR = 1.565 [0.647-3.790] P = 0.321, although rural patients were more likely to undergo colon resection (OR = 2.183 [0.938-5.079] P = 0.070). Furthermore, rural patients were much more likely to be readmitted than urban dwellers (OR = 4.700 [1.022-21.618] P = 0.047). CONCLUSIONS: AMI patients living in rural or small-town areas were more likely to be readmitted and tended to undergo colonic resection. Patients residing in higher income areas had a slightly higher risk of mortality but tended to be less likely to require ostomy or colonic resection. These findings suggest a potential need for postoperative care initiatives focused on AMI patients living in rural and lower income areas.

Stepping On Fall Prevention Program Reduces Falls in Older Adults: An Observational Prospective Study.

The purpose of the current study was to assess the impact of the Stepping On fall prevention program on the incidence of falls and frailty measures in older adults. Participants completed pre- and post-fall prevention program questionnaires and the Frail Scale Assessment at baseline and post-program. They also completed a follow-up questionnaire and Frail Scale Assessment at 6- and 12-month intervals post-program. Univariate analysis was performed comparing robust (n = 11), pre-frail (n = 29), and frail (n = 7) participants. Frail participants were significantly older (mean age = 77.7 years [SD = 4.9 years] vs. 74 years [SD = 5.9 years] vs. 70.4 [SD = 3.9], respectively; p = 0.026) and more likely to live alone (71.4% vs. 65.5% vs. 18.2%, respectively; p = 0.017) compared to pre-frail and robust participants. At 12-month post-program, reported falls and frailty scores decreased compared to baseline (12.8% vs. 29.8%, p = 0.044 and 0.91 [SD = 1.1] vs. 1.3 [SD = 1.082], respectively; p = 0.009). Data show that 41.4% of pre-frail participants at baseline improved to robust. Participation in Stepping On led to a decrease in reported falls and frailty scores 12 months post-program, suggesting that participation in the program may help delay frailty progression.

Admission Lymphopenia is Associated With Discharge Disposition in Blunt Chest Wall Trauma Patients.

BACKGROUND: Lymphopenia contributes to the immune suppression observed in critical illness. However, its role in the immunologic response to trauma remains unclear. Herein, we assessed whether admission lymphopenia is associated with poor outcomes in patients with blunt chest wall trauma (BCWT). METHODS: All adult patients with a Chest Abbreviated Injury Score (CAIS) ≥2 admitted to our Level I Trauma center between May 2009 and December 2018 were identified in our institution Trauma Registry. Patients with absolute lymphocyte counts (ALC) collected within 24 H of admission were included. Patients who died within 24 H of admission, had bowel perforation on admission, penetrating trauma, and burns were excluded. Demographics, injury characteristics, comorbidities, ALC, complications, and outcomes were collected. Lymphopenia was defined as an ALC ≤1000/µL. Association between lymphopenia and clinical outcomes of BCWT was assessed using multivariate analyses. P < 0.05 was considered significant. RESULTS: A total of 1394 patients were included; 69.7% were male; 44.3% were lymphopenic. On univariate analysis, lymphopenia was associated with longer in-hospital stay (11.6±10.2 versus 10.1±11.4, P = 0.009), in-hospital death (9.7% versus 5.8%, P = 0.006), and discharge to a healthcare facility (60.9% versus 46.4%, P < 0.001). Controlling for Injury Severity Score, age, gender, and comorbidities, the association between lymphopenia and discharge to another facility (SNF/rehabilitation facility/ACH) (OR = 1.380 [1.041-1.830], P = 0.025) remained significant. CONCLUSIONS: Lymphopenia on admission is associated with discharge requiring increased healthcare support. Routine lymphocyte count monitoring on admission may provide important prognostic information for BCWT patients.

Tourniquet Application for Bleeding Control in a Rural Trauma System: Outcomes and Implications for Prehospital Providers.

Introduction: Uncontrolled bleeding is a preventable cause of death in rural trauma. Herein, we examined the appropriateness, effectiveness, and safety of tourniquet application for bleeding control in a rural trauma system.Methods: Medical records of adult patients admitted to our academic Level I trauma center between July 2015 and December 2018 were retrospectively reviewed. Demographics (age, gender), injury (Injury severity score, Glascow Coma scale, mechanism of injury), tourniquet (type, tourniquet application site, tourniquet duration, place of application and removal, indication), and outcome data (complications such as amputation, acute kidney injury, rhabdomyolysis, or nerve palsy and mortality) were collected. Tourniquet indications, effectiveness, and complications were evaluated. Data were compared to those in urban settings.Results: Ninety-two patients (94 tourniquets) were identified, of which 58.7% incurred penetrating injuries. Eighty-seven tourniquets (92.5%) were applied in the prehospital setting. Twenty tourniquets (21.3%) were applied to patients without an appropriate indication. Two of these tourniquets were applied in a hospital setting, while 18 occurred in the prehospital setting (p = 0.638). Patients with a non-indicated tourniquet presented with a higher hemoglobin level on admission, received less packed red blood cell units within the first 24 hours of hospitalization, and were less likely to require surgery for hemostasis. None of the non-indicated tourniquets led to a complication. Indicated tourniquets were deemed ineffective in seven cases (9.5%); they were all applied in the prehospital setting. The average tourniquet time was 123 min in rural vs. 48 min in urban settings, p < 0.001. There was no significant difference in mortality, amputation rates and incidence of nerve palsy between the rural and urban settings.Conclusion: Even with long transport times, early tourniquet application for hemorrhage control in rural settings is safe with no significant attributable morbidity and mortality compared to published studies on urban civilian tourniquet use. The observed rates of non-indicated and ineffective tourniquets indicate suboptimal tourniquet usage and application. Opportunity exists for standardized hemorrhage control training on the use of direct pressure and pressure dressings, indications for tourniquet use, and effective tourniquet application.

Firework injuries remain high in years after legalisation: its impact on children.

PURPOSE: We evaluated the impact of Senate Bill 489 passed in May 2017, allowing the sale and use of fireworks in Iowa 1 June to 8 July and 10 December to 3 January, on hospital presentations for firework injuries in the state. To identify the public health implications of this law, we conducted a detailed subanalysis of hospital presentations to the two level I trauma centres. METHODS: Hospital presentations for firework injuries from 1 June 2014 to 31 July 2019 were identified using the Iowa Hospital Admission database and registries and medical records of Iowa's two level 1 trauma centres. Trauma centres' data were reviewed to obtain demographics, injury information and hospital course. Prefirework and postfirework legalisation state data were compared using negative binomial regression analysis. Trauma centre data detailing injuries were compared using χ2 and Mann-Whitney U tests as appropriate. RESULTS: Emergency department (ED) visits and hospital admissions for firework injuries increased in Iowa post-legalisation (B-estimate=0.598±0.073, p<0.001 and B-estimate=0.612±0.322, p=0.058, respectively). ED visits increased postlegalisation in July (73.6% vs 64.5%; p=0.008), reflecting an increase in paediatric admissions (81.8% vs 62.5%; p=0.006). Trauma centres' data showed similar trends. The most common injury site across both study periods was the hands (48.5%), followed by the eyes (34.3%) and face (28.3%). Amputations increased from 0 prelegalisation to 16.2% postlegalisation. CONCLUSION: Firework legalisation led to an increase in the number of admissions and more severe injuries.

Geriatric clinical screening tool for cervical spine injury after ground-level falls.

BACKGROUND: A consistent approach to cervical spine injury (CSI) clearance for patients 65 and older remains a challenge. Clinical clearance algorithms like the National Emergency X-Radiography Utilisation Study (NEXUS) criteria have variable accuracy and the Canadian C-spine rule excludes older patients. Routine CT of the cervical spine is performed to rule out CSI but at an increased cost and low yield. Herein, we aimed to identify predictive clinical variables to selectively screen older patients for CSI. METHODS: The University of Iowa's trauma registry was interrogated to retrospectively identify all patients 65 years and older who presented with trauma from a ground-level fall from January 2012 to July 2017. The relationship between predictive variables (demographics, NEXUS criteria and distracting injuries) and presence of CSI was examined using the generalised linear modelling (GLM) framework. A training set was used to build the statistical models to identify clinical variables that can be used to predict CSI and a validation set was used to assess the reliability and consistency of the model coefficients estimated from the training set. RESULTS: Overall, 2312 patients ≥65 admitted for ground-level falls were identified; 253 (10.9%) patients had a CSI. Using the GLM framework, the best predictive model for CSI included midline tenderness, focal neurological deficit and signs of trauma to the head/face, with midline tenderness highly predictive of CSI (OR=22.961 (15.178-34.737); p<0.001). The negative predictive value (NPV) for this model was 95.1% (93.9%-96.3%). In the absence of midline tenderness, the best model included focal neurological deficit (OR=2.601 (1.340-5.049); p=0.005) and signs of trauma to the head/face (OR=3.024 (1.898-4.815); p<0.001). The NPV was 94.3% (93.1%-95.5%). CONCLUSION: Midline tenderness, focal neurological deficit and signs of trauma to the head/face were significant in this older population. The absence of all three variables indicates lower likelihood of CSI for patients≥65. Future observational studies are warranted to prospectively validate this model.

A Prospective Comparison of Frailty Scores and Fall Prediction in Acutely Injured Older Adults.

BACKGROUND: Elderly (65 and older) fall-related injuries are a significant cause of morbidity and mortality. Although frailty predicts poor outcomes in geriatric trauma, literature comparing frailty scoring systems remains limited. Herein, we evaluated which frailty scoring system best predicts falls over time in the elderly. MATERIALS AND METHODS: Acute surgical patients 65 y and older were enrolled and prospectively observed. Demographics and frailty, assessed using the FRAIL Scale, Trauma Specific Frailty Index (TSFI), and Canadian Frailty Scale (CSHA-CFS), were collected at enrollment and 3 mo intervals following discharge for 1 y. Surveys queried the total number and timing of falls. Changes in frailty over time were assessed by logistic regression and area under the curve (AUC). RESULTS: Fifty-eight patients were enrolled. FRAIL Scale and CSHA-CFS scores did not change over time, but TSFI scores did (P ≤ 0.01). Worsening frailty was observed using TSFI at 6 (P ≤ 0.01) and 12 mo (P ≤ 0.01) relative to baseline. Mortality did not differ based on frailty using any frailty score. Increasing frailty scores and time postdischarge was associated with increased odds of a fall. AUC estimates with 95% CI were 0.72 [0.64, 0.80], 0.81 [0.74, 0.88], and 0.76 [0.68, 0.84] for the FRAIL Scale, TSFI, and CSHA-CFS, respectively. CONCLUSIONS: The risk of falls postdischarge were associated with increased age, time postdischarge, and frailty in our population. No scale appeared to significantly outperform the other by AUC estimation. Further study on the longitudinal effects of frailty is warranted.

Common Injuries Associated with Falls from Tree Stands in Iowa.

INTRODUCTION: Tree stand falls are a common injury among hunters. This study was designed to identify specific injury patterns and local and regional factors affecting access to and care for this unique trauma cohort in Iowa. METHODS: The University of Iowa trauma registry was retrospectively queried from 2004 to 2014 for patients with a mechanism of injury of fall from tree stands. Data are presented as mean±SD, median, and range, or raw number and percentages as appropriate. Correlation analyses were performed using the Spearman coefficient. RESULTS: Fifty-three patients were identified. Age was 44±14 (17-78) y. Median fall height was 4.6 m (15 ft), ranging from 1.5 to 12 m (5 to 40 ft). Transport times varied from <1 h to >7 h. Hypothermia was observed in 6 patients (11%). Two patients (4%) tested positive for alcohol. Three patients (6%) tested positive for drugs. Soft tissue injuries (32 [60%]; ie, lacerations and abrasions) were the most common, followed by 30 spine fractures (57%, including 11 lumbar and 10 thoracic fractures), 16 other bone fractures (30%), and 11 rib fractures (21%). Twenty-two patients underwent surgery. Median hospital length of stay was 4 d, ranging from 0 to 20 d. CONCLUSIONS: Tree stand falls lead to significant injuries. Hypothermia represents a significant risk for these patients, and remote location resulted in long transportation time. Improper use or poor condition of safety equipment contributed to falls and injuries in a few of our patients.

Safety and effectiveness of Factor Eight Inhibitor Bypassing Activity for direct oral anticoagulant-related hemorrhage reversal.

BACKGROUND: The incidence of patients who present with life-threatening bleeding complications has been increasing as the use of direct oral anticoagulation (DOAC) has increased. Therefore, effective reversal agents are urgently needed. Current guidelines recommend the use of prothrombin complex concentrates (PCCs) and activated PCCs (aPCC) for reversal of DOAC anticoagulant activity in the setting of traumatic and non-traumatic intracranial hemorrhage (ICH). However, little data is available. OBJECTIVE: Herein, we investigated the safety and effectiveness of Factor Eight Inhibitor Bypassing Activity [FEIBA (an aPCC)] in a population of patients who required emergent reversal of DOAC for hemorrhage or urgent surgical interventions. METHODS: This is a case series study. Medical records from patients who required emergent reversal of DOAC for life threatening hemorrhage or urgent surgical interventions were collected from February 1, 2014, to April 1, 2017 and reviewed. Data, including demographics as well as safety, outcomes, and dosing of FEIBA for reversal of DOAC effects were collected and descriptive statistics were obtained. RESULTS: Forty-two patients who received FEIBA were included in the study. The rates of thrombotic events (10%), hemorrhage progression (10%), and observed mortality (29%) were similar to rates previously published in the limited literature evaluating aPCC use in this population. CONCLUSION: This case series suggests that FEIBA administration is relatively safe and effective to reverse DOACs in the setting of hemorrhage or need for urgent surgical procedures. Until target-specific reversal agents are available, future studies are warranted to evaluate the effectiveness of aPCC administration for DOAC-associated hemorrhagic complications.

Trace Element Supplementation in Burn Patients: Exploring the Relationship Between Burn Size and Mineral Needs.

Trace element deficiency is an adverse nutritional outcome that can occur with burn injuries, and can interfere with a patient's recovery. The aim of this study was to review the efficacy of our predominately enteral trace element supplementation strategy and determine the burn size at which patients are at risk for trace element deficiency. We reviewed 53 burn patients admitted to our burn center from August 1, 2019 to May 31, 2022 who had their trace element levels and C-reactive protein monitored in two-week increments. Receiver operating characteristic analysis indicated a 22.1% BSAB cutoff for zinc supplementation to prevent deficiency with 91.7% sensitivity and 92.6% specificity, and a 27.5% BSAB cutoff with 88.9% sensitivity and 81% specificity for copper. No patient in our cohort developed selenium deficiency, regardless of burn size. Patients with greater than 30% body surface area burned developed deficiencies in both zinc and copper within the first two weeks of hospitalization. Our results provide guidance for trace element replacement based on burn size.

Education of trauma patients on opioids and pain management: A quality improvement project.

BACKGROUND: Our acute care surgery team sustainably launched a pain management quality improvement project to reduce opioid prescriptions without affecting pain control in our elective surgery patients that was adopted on the inpatient acute care surgery service. Consequently, we implemented patient education on opioids and pain management aiming at decreasing opioid use without compromising pain management for acutely injured patients on the trauma service. METHODS: Trauma patients admitted from August 1, 2021, to July 31, 2022, and discharged to home were included. Pain management education started on February 2022. Demographics, injury severity scores (ISSs), preadmission opioid and adjunct use, and type/dose of opioids and nonopioid adjuncts prescribed 24 hours predischarge and at discharge were collected. Opioids were converted to oral morphine milligram equivalents (MME). Phone calls for pain and opioid prescription refills were collected. The pre- and posteducation groups were compared using univariate analysis. Multivariate analyses were conducted to identify factors associated with phone calls for pain and opioid refills. RESULTS: Three hundred sixty-eight patients were included, 200 pre- and 168 posteducation. MME prescribed at discharge was positively associated with 24-hour predischarge MME (B = 0.010 [0.007-0.012], P < .001) and negatively associated with preinjury opioid use (B = -0.405 [-0.80 to -0.008], P = .045). Patient education led to an increased number of adjuncts prescribed (P < .008), decreased phone calls for pain (OR = 0.356 [0.165-0.770], P = .009), and decreased opioid refills (OR = 0.297 [0.131-0.675], P = .004), but no change in opioid prescriptions. CONCLUSION: Patient education on opioids and pain management led to decreased phone calls for inadequate pain management and decreased number of opioid refills.

Is Frailty Discouraging Surgeons from Performing Thoracolumbar Fusion? A Retrospective Study.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To evaluate whether frailty scoring is associated with adverse outcomes and management of thoracolumbar fractures (TLF) patients. SUMMARY OF BACKGROUND DATA: Trauma patients with TLF often face longer recovery. The Canadian Study of Health and Aging clinical frailty scale (CSHA-CFS) predicts outcomes in older trauma patients. METHODS: Adult trauma patients admitted from 2017 to 2021 who presented with TLF were included. Frailty was scored using CSHA-CFS. Endpoints were in-hospital mortality, hospital length of stay, surgery, complications, and discharge disposition. Multivariate analyses adjusting for baseline characteristics were performed. P<0.05 was considered significant. RESULTS: Overall, 1456 patients were included; 1013 fit, 240 pre-frail, and 203 frail. Frail patients underwent fewer surgeries (OR=0.5 [0.32-0.77], P=0.002). TL fusion was associated with lower mortality (OR=0.31 [0.11-0.85], P=0.024). Pre-frailty and frailty were associated with increased risk of pneumonia (OR=2.522 [1.428-4.456], P=0.001; OR=2.93 [1.32-6.54], P=0.008, respectively) and death (OR=3.581 [1.853-6.921], P<0.001; OR=2.46 [1.07-5.67], P=0.035). Pre-frail and frail patients were more likely to discharge to skilled nursing facilities (OR=1.687 [1.024-2.780], P=0.04; OR=4.89 [2.66-9.0]), P<0.001). CONCLUSIONS: Pre-frailty and frailty were associated with poor outcomes and higher level of care at discharge. Frail patients were less likely to undergo TL fusion, despite its association with improved survival. This suggests frailty should not discourage surgeons from performing thoracolumbar fusion. Frailty scoring upon admission may help guide management and set realistic expectations for patients and their families.

The effect of damage control laparotomy on surgical-site infection risks after emergent intestinal surgery.

INTRODUCTION: Damage-control laparotomy has been widely used in general surgery. However, associated surgical-site infection risks have rarely been investigated. Damage-control laparotomy allows for additional opportunities for decontamination. We hypothesized that damage-control laparotomy would be associated with lower surgical-site infection risks compared with laparotomy with only primary fascial closure or with primary fascial and skin closure. METHODS: Patients admitted for emergent intestinal surgery from 2006 to 2021 were included. Multivariate analyses were performed to identify surgical-site infection-associated risk factors. Although variables like laparotomy type (damage-control laparotomy, primary fascial closure, and primary fascial and skin closure) were provided by National Surgical Quality Improvement Program, other variables such as number of operations were retrospectively collected. P < .05 was considered significant. RESULTS: Overall, 906 patients were included; 213 underwent damage-control laparotomy, 175 primary fascial closure, and 518 primary fascial and skin closure. Superficial, deep, and organ-space surgical-site infection developed in 66, 6, and 97 patients, respectively. Compared with primary fascial and skin closure, both damage-control laparotomy (odds ratio, 0.30 [95% CI, 0.13-0.73], P = .008) and primary fascial closure (odds ratio, 0.09 [95% CI, 0.02-0.37], P = .001) were associated with lower superficial incisional surgical-site infection but not organ-space surgical-site infection risk (odds ratio, 0.80 [95% CI, 0.29-2.19] P = .667 and odds ratio, 0.674 [95% CI, 0.21-2.14], P = .502, respectively). Body mass index was associated with increased risk of superficial incisional surgical-site infection (odds ratio, 1.06 [95% CI, 1.03-1.09], P < .001) whereas frailty was associated with organ space surgical-site infection (odds ratio, 3.28 [95% CI, 1.29-8.36], P = .013). For patients who underwent damage-control laparotomy, the number of operations did not affect risk of either superficial incisional surgical-site infection or organ space SSI. CONCLUSION: Herein, compared with primary fascial and skin closure, both damage-control laparotomy and primary fascial closure were associated with lower superficial but not organ space surgical-site infection risks. For patients who underwent damage-control laparotomy, number of operations did not affect surgical-site infection risks.

Subhypnotic Intravenous Ketamine Improves Patient Satisfaction With Burn Wound Care: A Quality Improvement Project.

Despite advancements in pain management for burn injuries, analgesia often fails to meet our patients' needs. We hypothesized that low doses of intravenous (IV) ketamine as an adjunct to our current protocol would be safe, improving both nurse and patient satisfaction with analgesia during hydrotherapy. Burn patients admitted who underwent hydrotherapy from June 1, 2021, to June 30, 2023 were surveyed. Ketamine was administered with the standard opioid-midazolam regimen. Demographics, oral morphine equivalents, midazolam, ketamine doses and time of administration, and adverse events were collected. Patient and nurse satisfaction scores were collected. The ketamine and no-ketamine groups were compared. P < .05 was considered significant. Eighty-five hydrotherapies were surveyed, 47 without ketamine, and 38 with ketamine. Demographics, comorbidities, %TBSA, and hospital length of stay were not different. The median amount of ketamine given was 0.79 mg/kg [0.59-1.06]. Patients who received ketamine were more likely to receive midazolam (100% vs 61.7%; P < .001), and both oral and IV opioids (94.7% vs 68.1%; P = .002) prior to hydrotherapy and less likely to receive rescue opioids or midazolam during hydrotherapy. Two patients in the ketamine group had hypertension (defined as SBP > 180) that did not require treatment. Nurses tended to be more satisfied with patient pain control when ketamine was used (10 [8-10] vs 9 [7-10], P = .072). Patient satisfaction was higher in the ketamine group (10 [8.8-10] vs 9 [7-10], P = .006). Utilizing subhypnotic dose of IV ketamine for hydrotherapy is safe and associated with increased patient satisfaction.

Optimizing burn wound procedural pain control, efficiency, and satisfaction through integrated nurse and physician education.

Herein, we report the results of a quality improvement project (QI). Following a review of the burn unit practices, a nursing-led, physician supported educational intervention regarding optimal timing, dosage, and indication for medications used during hydrotherapy, including midazolam and opioids, was implemented. We hypothesized that such intervention would support improvement in both nurse and patient satisfaction with pain control management. Patients undergoing hydrotherapy were surveyed. Demographics, opioid dose prescribed (oral morphine equivalents), midazolam use, timing of administration, and adverse events were collected. Patient pain scores (1-10) before and after hydrotherapy and patient and nurse satisfaction scores (1-10) after hydrotherapy were collected. The pre- and post-education populations were compared. P < 0.05 was considered significant. Post-education, administration of opioids (59.1% v. 0%, p < 0.001) and midazolam (59.1% vs. 10.4%; p < 0.001) prior to hydrotherapy significantly improved, leading to fewer patients requiring rescue opioids during hydrotherapy (25% vs. 74%, p < 0.001). Hydrotherapy duration significantly decreased post-education (19 [13.3-30] min vs. 32 [18-43] min, p = 0.003). Nurses' ratings of their patient's pain control (9 [7.3-10] vs. 7.5 [6-9], p = 0.004) and ease of procedure (10 [9,10] vs. 9 [7.8-10], p = 0.037) significantly improved. Patients' pain management satisfaction rating did not change, but the number of subjects rating their pain management as excellent tended to increase (36.4% vs. 20%, p = 0.077). Nursing led, physician supported, education can improve medication administration prior to and during hydrotherapy, increasing the ease of the procedure as well as staff satisfaction.

Use and Outcomes of Dexamethasone in the Management of Malignant Small Bowel Obstruction.

Objective: To describe rates of dexamethasone use in the nonoperative management of malignant small bowel obstruction (mSBO) and their outcomes. Background: mSBO is common in patients with advanced abdominal-pelvic cancers. Management includes prioritizing quality of life and avoiding surgical intervention when possible. The use of dexamethasone to restore bowel function is recommended in the National Comprehensive Cancer Network guidelines for mSBO. Yet, it is unknown how often dexamethasone is used for mSBO and whether results from nonresearch settings support its use. Methods: This is a multicenter retrospective cohort study including unique admissions for mSBO from January 1, 2019 to December 31, 2021. Dexamethasone use and management outcomes were summarized with descriptive statistics and multiple logistic regression. Results: Among 571 admissions (68% female, mean age 63 years, 85% history of abdominal surgery) that were eligible and initially nonoperative, 26% [95% confidence interval (CI) = 23%-30%] received dexamethasone treatment (69% female, mean age 62 years, 87% history of abdominal surgery). Dexamethasone use by site ranged from 13% to 52%. Among dexamethasone recipients, 13% (95% CI = 9%-20%) subsequently required nonelective surgery during the same admission and 4 dexamethasone-related safety-events were reported. Amongst 421 eligible admissions where dexamethasone was not used, 17% (95% CI = 14%-21%) required nonelective surgery. Overall, the unadjusted odds ratio (OR) for nonelective surgery with dexamethasone use compared to without its use was 0.7 (95% CI = 0.4-1.3). Using multiple logistic regression, OR after adjusting for site, age, sex, history of abdominal surgery, nasogastric tube, and Gastrografin use was 0.6 (95% CI = 0.3-1.1). Conclusion: Dexamethasone was used in about 1 in 4 eligible mSBO admissions with high variability of use between tertiary academic centers. This multicenter retrospective cohort study suggested an association between dexamethasone use and lower rates of nonelective surgery, representing a potential opportunity for quality improvement.

Effects of calorie restriction and IGF-1 receptor blockade on the progression of 22Rv1 prostate cancer xenografts.

Calorie restriction (CR) inhibits prostate cancer progression, partially through modulation of the IGF axis. IGF-1 receptor (IGF-1R) blockade reduces prostate cancer xenograft growth. We hypothesized that combining calorie restriction with IGF-1R blockade would have an additive effect on prostate cancer growth. Severe combined immunodeficient mice were subcutaneously injected with 22Rv1 cells and randomized to: (1) Ad libitum feeding/intraperitoneal saline (Ad-lib); (2) Ad-lib/20 mg/kg twice weekly, intraperitoneal ganitumab [anti-IGF-1R antibody (Ad-lib/Ab)]; (3) 40% calorie restriction/intraperitoneal saline (CR); (4) CR/ intraperitoneal ganitumab, (CR/Ab). CR and ganitumab treatment were initiated one week after tumor injection. Euthanasia occurred 19 days post treatment. Results showed that CR alone decreased final tumor weight, plasma insulin and IGF-1 levels, and increased apoptosis. Ganitumab therapy alone reduced tumor growth but had no effect on final tumor weight. The combination therapy (CR/Ab) further decreased final tumor weight and proliferation, increased apoptosis in comparison to the Ad-lib group, and lowered plasma insulin levels relative to the Ad-lib and Ad-lib/Ab groups. Tumor AKT activation directly correlated with plasma IGF-1 levels. In conclusion, whereas ganitumab therapy modestly affected 22Rv1 tumor growth, combining IGF-1R blockade with calorie restriction resulted in a significant decrease in final tumor weight and improved metabolic profile.
