Fragmentation of Care After Geriatric Trauma: A Nationwide Analysis of outcomes and Predictors

The health care system for the elderly is fragmented, that is worsened when readmission occurs to different hospitals. There is limited investigation into the impact of fragmentation on geriatric trauma patient outcomes. The aim of this study was to compare the outcomes following readmissions after geriatric trauma. The Nationwide Readmissions Database (2016-2017) was queried for elderly trauma patients (aged ≥65 years) readmitted due to any cause. Patients were divided into 2 groups according to readmission: index vs non-index hospital. Outcomes were 30 and 180-day complications, mortality, and the number of subsequent readmissions. Multivariable logistic regression was performed to analyze the independent predictors of fragmentation of care. A total of 36,176 trauma patients were readmitted, of which 3856 elderly patients (aged ≥65 years) were readmitted: index hospital (3420; 89%) vs non-index hospital (436; 11%). Following 1:2 propensity matching, elderly with non-index hospital readmission had higher rates of death and MI within 180 days (P = .01 and .02, respectively). They had statistically higher 30 and 180-day pneumonia (P < .01), CHF (P < .01), arrhythmias (P < .01), MI (P < .01), sepsis (P < .01), and UTI (P < .01). On multivariable binary logistic regression analysis, pneumonia (OR 1.70, P = .03), congestive heart failure (CHF) (OR 1.80, P = .03), female gender (OR .72, P = .04), and severe Head and Neck trauma (AIS≥3) (OR 1.50, P < .01) on index admission were independent predictors of fragmentation of care. While the increase in time to readmission (OR 1.01, P < .01) was also associated independently with non-index hospital admission. Fragmented care after geriatric trauma could be associated with higher mortality and complications.

Non-operative management of cirrhotic patients with acute calculous cholecystitis: How effective is it?

INTRODUCTION

Nonoperative management (NOM) of acute calculous cholecystitis (ACC) in patients with cirrhosis was proposed. We examined the outcomes of cirrhotic patients with ACC treated with cholecystectomy compared to NOM.

METHODS

We analyzed the 2017-Nationwide Readmissions Database including cirrhotic patients with ACC. Patients were stratified: cholecystectomy, percutaneous cholecystostomy (PCT), and antibiotics only.

PRIMARY OUTCOMES

complications, failure of NOM.

SECONDARY OUTCOMES

mortality, length of stay (LOS), and charges.

RESULTS

3454 patients were identified. 1832 underwent cholecystectomy, 360 PCT, and 1262 were treated with antibiotics. PCT patients had higher mortality 16.9% vs. the antibiotics group 10.9% vs. cholecystectomy group 4.2%. PCT patients had longer LOS, but lower charges compared to the operative group. Failure of NOM was 28.2%. On regression, PCT was associated with mortality.

CONCLUSION

ACC remains a morbid disease in cirrhosis patients. One in three failed NOM, had longer LOS, and higher mortality. Further studies are warranted to identify predictors of NOM failure.

Improving blunt cerebrovascular injury screening in motor vehicle collision patients: Does airbag deployment matter?

BACKGROUND

Motor vehicle collisions (MVCs) can cause blunt cerebrovascular injury (BCVI). Exploring MVC characteristics that increase BCVI may reduce missed injuries. This study aims to evaluate the association between airbag deployment and BCVI.

METHODS

We analyzed the 2016-Trauma Quality Improvement Database including adult MVC drivers. Patients were stratified: airbag deployment(A+) and no-airbag deployment(A-). Outcomes were BCVI, and cervical spine injuries (CSI).

RESULTS

A total of 122,973 patients were identified: A+: 106,492, and A-: 16,481. The incidence of BCVI was 1907 (1.6%): and CSI was 20,711 (16.8%). A+ patients had a higher rate of BCVI (1.6% vs. 1.1%; p < 0.001), but a lower rate of CSI (16.2% vs. 21.4%; p < 0.001). On regression analysis, A+ was associated with BCVI (1.419[1.184-1.701]; p < 0.001) but was protective for CSI (0.767[0.672-0.878]; p < 0.001).

CONCLUSION

A+ may be an unrecognized risk factor for BCVI even for patients without a CSI. Expanding BCVI screening criteria to include A+ may reduce missed injuries.

Venous thromboembolism as the first sign of malignancy

BACKGROUND

Venous thromboembolism (VTE) is commonly associated with hypercoagulability in patients with cancer; however, there have been few investigations of VTE as the first sign of malignancy and even fewer performed in the United States. The aim of our study was to evaluate the incidence and predictors of unrecognized malignancy in patients presenting with VTE.

METHODS

We performed a 1-year retrospective analysis of the Nationwide Readmission Database, including patients aged 18 years or older, presenting with a primary diagnosis of deep vein thrombosis (DVT) or a pulmonary embolism (PE). Patients known to have preexisting malignant diseases were excluded. Outcomes included the rate of newly diagnosed malignancy within 6 months from the discovery of VTE and demographic or associated illness predictors for the diagnosis of malignancy. A regression analysis was performed, based on which a VTE malignancy score was developed.

RESULTS

A total of 116,048 patients were identified with VTE (49.8% DVT, 41.7% PE, 8.6% DVT and PE), 16% (n = 18,294) with malignancy. Of the remaining 97,754 patients, 31% were readmitted within 6 months. The incidence of newly diagnosed malignancy within 6 months was 2.4% (n = 2354). The most common malignancies were gastrointestinal in origin (29.2%). Demographic and diagnostic predictors for malignancy included age 65 years or older, female sex, inferior vena cava (IVC) thrombus, upper extremity thrombus, and a Charlson Comorbidity Index score of 5 or more. Receiver operating characteristic curve analysis found a cutoff VTE Malignancy score of 3 (sensitivity, 86%; specificity, 89%) to be predictive of an increased risk of a newly discovered malignancy within 6 months.

CONCLUSIONS

VTE can be a risk indicator of underlying malignancy. Validation of a patient risk stratification score using multiple demographic or comorbid predictors for VTE on index admission may offer an opportunity for earlier diagnosis of occult malignancy.

Hospitalization Costs and Outcomes of Open, Laparoscopic, and Robotic Liver Resections

INTRODUCTION

Most liver resections performed in the United States are open. With the ever-increasing role of robotic surgery, our study's role is to assess national outcomes based on the surgical approach.

METHODS

We performed a retrospective analysis of the 2015 National Readmission Database (NRD). We selected patients undergoing open, laparoscopic, and robotic hepatectomy. Propensity score matching was performed to match the three groups in terms of demographics, hospital characteristics, and resection type. Our primary outcome was 6-month readmission rates and associated costs.

RESULTS

3,872 patients were included in the analysis (open = 3,420, laparoscopic = 343, and robotic = 109). Robotic liver resection has lower 6-month readmission rates (18.3%) than the laparoscopic (26.7%) and open (30%) counterparts. The robotic approach was more cost-effective ($127,716.56 ± 12,567.31) than the open ($157,880.82 ± 18,560.2) and laparoscopic approach ($152,060.78 ± 8,890.13) in terms of the total cost which includes cost per readmission.

CONCLUSIONS

There is a financial benefit of using robotics in terms of cost, hospital length of stay, and readmission rates in patients undergoing liver resection, cost.

Using Google Trends and Google to investigate public information needs in relation to dementia and dementia medication

Introduction

Although dementia is a global public health concern, there remains a large variability in public awareness of the condition and associated medications (1,2). Google Trends, a publicly available online resource, acts as a useful tool in the analysis of internet search activity and population behaviour, with applications across field of healthcare. It has not been used to date to investigate information needs in relation to dementia and dementia medications.

Aim

To investigate public information needs regarding dementia and dementia medications, by evaluating data from Google Trends and Google.

Methods

Google Trends was queried using search terms relating to dementia and dementia medications, for the five-year period to January 2020 and the 12-month period to January 2020, for United Kingdom (UK) and Ireland domains. The “top related queries” for each search term were extracted and recorded, and thematic analysis undertaken. The top ten Google search results for each search term were recorded, and assigned a rank based on their page position, from 1 (first search result, highest rank) to 10 (lowest rank); count (the number of times the website domain appeared near the top of the search results) and average rank (i.e. ordinal position) were calculated for each domain. Google Trends was also queried using the term “dementia” for the UK domain, from 2004 to February 2020, and Loess Seasonal Trend Decomposition undertaken using R software to determine seasonality patterns in internet searching.

Results

Thematic analysis highlighted that the public sought information on dementia types, causes, signs and symptoms, diagnosis, prognosis, care and charitable organisations. Themes were broadly similar across time periods and UK/Ireland domains, with minor differences observed, including increased interest in research and development in 12-month UK data, and greater interest in charitable/government support in Ireland. The public sought information on acetylcholinesterase inhibitors and memantine, their indications, doses, formulations, side effects, antipsychotic use for agitation, information sources for dementia medications, and medications for co-morbidities. Analysis of search results, count and average rank revealed that the public were often directed to high-quality evidence-based websites for condition and medication-related search terms, though some less reliable information sources also featured. Seasonal variation was observed; a modest swing in interest was exhibited over the year, peaking in May (correlating with Dementia Action Week) and falling to its lowest level in August. Overall a steady increase in search interest for “dementia’” over time was observed.

Conclusion

The public sought basic information about these subjects, and were often, but not always, directed to high-quality evidence-based websites. Public awareness of, and interest in, dementia is increasing, and future public health campaigns should seek to build on the success of previous campaigns. The strength of this study lies in the use of Google Trends and Google to investigate information needs in relation to dementia and dementia medications; to the best of our knowledge, this is the first study to do so. Limitations must be considered; it can be difficult to draw absolute conclusions from Google Trends data alone, and results should be interpreted with caution.

Subjective and objective social status: associations with psychosocial predictors and oral health

OBJECTIVE

While social status and health have been investigated, there is less focus on the effects of objective and subjective social status and psychosocial factors. This study aimed to investigate oral health impacts by subjective social status (SSS) and psychosocial predictors stratified by subjective social status.

METHODS

A random cross-sectional sample of 45-54-year old South Australians was surveyed in 2004-05. Oral health impact was assessed using OHIP-14. Socio-economic status was determined using objective (income) and subjective (McArthur scale) measures. Psychosocial variables comprised social support, health self-efficacy, coping and affectivity.

RESULTS

Responses were collected from 986 persons (response rate=44.4%). Lower SSS was more frequently observed in the low (70.2%) than high-income group (28.5%). Lower SSS was associated (p⟨0.05) with lower education, social support, health competence, and coping, but higher negative affect within income groups. The interaction of SSS and income showed OHIP was consistently lower at high SSS regardless of higher or lower income, but at low SSS, OHIP was higher (p⟨0.05) in the lower than higher income group.

CONCLUSIONS

SSS was associated with income. Their interaction indicated low SSS in combination with low income was associated with higher oral health impacts.

Multicenter Validation of the Revised Assessment of Bleeding and Transfusion (RABT) Score for Predicting Massive Transfusion

BACKGROUND

Massive transfusion (MT) is a lifesaving treatment for hemorrhaging patients. Predicting the need for MT is crucial to improve survival. The aim of our study was to validate the Revised Assessment of Bleeding and Transfusion (RABT) score to predict MT in a multicenter cohort of trauma patients.

METHODS

We performed a (2015-2017) analysis of adult (age ≥ 18 year) trauma patients who had a high-level trauma team activation at three Level I trauma centers. The RABT was calculated using the 4-point score [blunt (0)/penetrating trauma (1), shock index ≥ 1 (1), pelvic fracture (1), and FAST positive (1)]. A RABT score of ≥ 2 was used to predict MT (≥ 10 units of packed red blood cells within 24 h). The area under the receiver operating characteristic curve (AUROC) was calculated to assess the score's predictive power compared to the Assessment of Blood Consumption (ABC) score.

RESULTS

We analyzed 1018 patients: 216 (facility I), 363 (facility II), and 439 (facility III). The mean age was 41 ± 19 year, and the injury severity score (ISS) was 29 [22-36]. The overall MT rate was 19%. The overall AUROC of RABT ≥ 2 was 0.89. The sensitivity of the RABT ≥ 2 was 78%, and the specificity was 91%. The RABT score had a higher sensitivity (78% vs. 69%) and specificity (91% vs. 82%) than the ABC score.

CONCLUSION

The RABT score is a valid tool to predict MT in severely injured trauma patients. It is an objective score that aids clinicians in predicting the need for MT to mobilize blood products and minimize the waste of resources.

Temporomandibular dysfunction among working Australian adults and association with workplace effort-reward imbalance

OBJECTIVES

To explore the prevalence of temporomandibular dysfunction (TMD) among working Australian adults and examine whether workplace effort-reward imbalance is associated with TMD.

METHOD

Data were from Australia's National Survey of Adult Oral Health (NSAOH) 2004-06, a cross-sectional stratified clustered sample of Australian adults. The NSAOH data included information from a Computer Assisted Telephone Interview, self-complete questionnaire and oral epidemiological examination. Data included demographics, socio-economic characteristics, caries experience, diagnostic criteria for TMD, the Perceived Stress Scale (PSS) and a modified version of the Effort-Reward Imbalance instrument (ERI) where ERI ratio is the weighted ratio of workplace effort/reward subscales. Subpopulation analysis for working adults was conducted including complex sample descriptive statistics, bivariate and multivariable logistic regression models.

RESULTS

NSAOH had 4014 participants with 2329 (65.1%, SE=1.3%) working adults included in the subpopulation analysis. Among working adults, TMD prevalence was 9.4% (SE=1.0%), which was slightly less than population prevalence (PR=9.9%, SE=0.8%), and was higher for females (PR=12.4%, SE=1.4%), people aged ⟨35 years (PR=11.2%, SE=2.2%) and uninsured (PR=11.8%, SE=1.7%). TMD prevalence was associated with the ERI ratio (OR=2.5, 95% CI: 1.3-4.5) and PSS scores (OR=1.1, 95% CI: 1.0-1.09) in bi-variate associations. In multivariable logistic regression, TMD was associated with being female (OR=2.1, 95% CI:1.3-3.6), university qualified (OR=0.43, 95%CI: 0.21-0.88) and with the ERI ratio (OR=2.63, 95% CI: 1.47-4.72).

CONCLUSION

Greater effort-reward imbalance in the workplace is a psychosocial risk factor for TMD. This finding might need to be considered by clinicians managing TMD patients with need for investigating the efficacy of workplace stress management interventions.

Hepatectomy for Breast Cancer Metastasis and Sarcoma are more likely to have Adverse Outcomes than Hepatectomy for Primary Hepatocellular Cancer or for Colorectal Metastasis

INTRODUCTION

Outcomes for hepatectomy for breast cancer metastasis and sarcomatous disease processes are not well defined in literature. We sought to use a national database to identify outcomes in these patients compared to subset of patients more well studied in literature - primary Hepatocellular cancer patients and patients with colorectal metastasis.

METHODS

We identified patients undergoing major hepatectomy (≥ 3 segments) for primary hepatocellular cancer (HCC), sarcoma metastasis, breast cancer metastasis, and colorectal metastasis using NSQIP database. The Primary outcome measure was 30-day mortality. Secondary outcome measures were 30-day readmission and complication rates.

RESULTS

A total of 5580 patients underwent major hepatectomy during the study period. Patients who underwent hepatectomy for breast cancer metastasis had higher incidence of in-hospital complications (37%) compared to sarcoma (29%), colon (26%), and HCC patients (24%) and 30-days readmission rate (37% vs. 29% - sarcoma vs. 26% - colon vs. 25% HCC). There was no difference in 30-days mortality among the groups.

CONCLUSION

Patients undergoing major hepatectomies for breast cancer metastasis and sarcoma are more likely to have adverse outcomes than compared to their counterparts. This difference highlights the lack of experience in managing breast cancer and sarcoma with metastatic disease to the liver. This also highlights the difference in tumor biology among all the lesions we studied. An extensive discussion should take place when dealing with breast and sarcoma lesions in the liver because of these outcomes.

Readmission With Major Abdominal Complications After Penetrating Abdominal Trauma

BACKGROUND

Despite improvements in operative techniques, major abdominal complications (MACs) continue to occur after penetrating abdominal trauma (PAT). This study aimed to evaluate the burden of MAC after PAT.

METHODS

The (2012-2015) National Readmission Database was queried for all adult (age ≥18 y) trauma patients with penetrating injuries who underwent exploratory laparotomy and were readmitted within 6 mo of index hospitalization discharge. Patients were stratified by firearm injuries (FIs) and stab injuries (SIs). Primary outcomes were rates of MAC: intra-abdominal abscesses (IAAs), superficial surgical site infection (SSI), and fascial dehiscence within 6 mo after discharge. Secondary outcomes were both nonabdominal complications and mortality, postdischarge, and 6-mo readmission. Regression analysis was performed.

RESULTS

A total of 4473 patients (FI, 2326; SI, 2147) were included in the study; the mean age was 32 ± 14 y, the Injury Severity Score was 19 (15-25), and 23% underwent damage control laparotomy (DCL). The rate of MAC within 6 mo was 22% (IAA 19%, SSI 7%, and fascial dehiscence 4%). Patients with FIs had a higher rate of IAA (27% versus 10%; P < 0.01), SSI (11% versus 3%; P < 0.01), fascial dehiscence (5% versus 3%; P = 0.03), nonabdominal complications (54% versus 24%; P < 0.01), and postdischarge mortality (8% versus 6%; P < 0.01) compared with patients with SIs . On regression analysis, DCL (P < 0.01), large bowel perforation (P < 0.01), biliary-pancreatic injury (P < 0.01), hepatic injury (P < 0.01), and blood transfusion (P = 0.02) were predictors of MAC.

CONCLUSIONS

MAC developed in one in five patients after PAT. FIs have a higher potential for hollow viscus injury and peritoneal contamination, and are more predictive of MAC and nonabdominal complications, especially after DCL.

Non-neurologic organ dysfunction plays a major role in predicting outcomes in pediatric traumatic brain injury

BACKGROUND

Nonneurological organ dysfunction (NNOD) occurs after traumatic brain injury (TBI) and is associated with mortality. The aim of our study was to evaluate the prevalence of NNOD and its association with outcomes in pediatric patients with TBI. We hypothesized that NNOD is associated with worse outcomes in pediatric patients with severe TBI.

METHODS

We performed a 4-year (2013-16) analysis of our prospectively maintained TBI database. All patients (age < 18) with an isolated-severe TBI (head-abbreviated injury scale: AIS ≥ 3 & extracranial-AIS < 3) were included. NNOD was measured using the pediatric multiple organ dysfunction (P-MOD) score. Outcomes were in-hospital mortality, Glasgow Outcome Scale-Extended (GOS-E), and adverse discharge disposition: rehabilitation or skilled nursing facility (SNF). Regression analysis was performed.

RESULTS

We analyzed 292 patients. Mean age was 11 ± 6 years, 57% were male and the mortality rate was 18.1%. The incidence of NNOD was 35%. The most common dysfunctional organ system was the respiratory (25%) followed by the cardiovascular (12%). On regression analysis, the presence of at least one NNOD was independently associated with in-hospital mortality (OR 2.1 [1.7-2.9]; p < 0.01), low GOS-E (OR 1.8 [1.5-2.3]; p < 0.01), and SNF disposition (OR 1.7 [1.2-2.1]; p < 0.01).

CONCLUSION

NNOD develops in one of every three severe TBI pediatric patients and is independently associated with adverse outcomes. Identification of NNOD in pediatric TBI and focusing on management of NNOD could improve outcomes.

Early Enteral Nutrition in Geriatric Burn Patients: Is There a Benefit?

Nutrition is a critical component of acute burn care and wound healing. There is no consensus over the appropriate timing of initiating enteral nutrition in geriatric burn patients. This study aimed to assess the impact of early enteral nutrition on outcomes in this patient population. We performed a 1-year (2017) analysis of the American College of Surgeons Trauma Quality Improvement Program and included all older adult (age ≥65 years) isolated thermal burn patients who were admitted for more than 24 hr and received enteral nutrition. Patients were stratified into two groups based on the timing of initiation of feeding: early (≤24 hr) vs late (>24 hr). Multivariate logistic regression was performed to control for potential confounding factors. Outcome measures were hospital and intensive care unit lengths of stay, in-hospital complications, and mortality. A total of 1,004,440 trauma patients were analyzed, of which 324 patients were included (early: 90 vs late: 234). The mean age was 73.9 years and mean TBSA burnt was 31%. Patients in the early enteral nutrition group had significantly lower rates of in-hospital complications and mortality (15.6% vs 26.1%; P = 0.044), and a shorter hospital length of stay (17 [11,23] days vs 20 [14,24] days; P = 0.042) and intensive care unit length of stay (13 [8,15] days vs 17 [9,21] days; P = 0.042). In our regression model of geriatric burn patients, early enteral nutrition was associated with improved outcomes. The cumulative benefits observed may warrant incorporating early enteral nutrition as part of intensive care protocols.

Number and Type of Complications Associated With Failure to Rescue in Trauma Patients

BACKGROUND

Failure to rescue (FTR) is becoming a ubiquitous metric of quality care. The aim of our study is to determine the type and number of complications associated with FTR after trauma.

METHODS

We reviewed the Trauma Quality Improvement Program including patients who developed complications after admission. Patients were divided as the following: "FTR" if the patient died or "rescued" if the patient did not die. Logistic regression was used to ascertain the effect of the type and number of complications on FTR.

RESULTS

A total of 25,754 patients were included with 972 identified as FTR. Logistic regression identified sepsis (odds ratio [OR] = 6.61 [4.72-9.27]), pneumonia (OR = 2.79 [2.15-3.64]), acute respiratory distress syndrome (OR = 4.6 [3.17-6.69]), and cardiovascular complications (OR = 24.22 [19.39-30.26]) as predictors of FTR. The odds ratio of FTR increased by 8.8 for every single increase in the number of complications.

CONCLUSIONS

Specific types of complications increase the odds of FTR. The overall complication burden will also increase the odds of FTR linearly.

Prospective evaluation of preoperative cognitive impairment and postoperative morbidity in geriatric patients undergoing emergency general surgery

BACKGROUND

Cognitive impairment (CI) is common in geriatric patients. We aimed to evaluate the prevalence and impact of CI on outcomes in geriatric patients undergoing emergency general surgery (EGS).

METHODS

We performed a (2017-2018) prospective analysis of patients (age ≥65y) who underwent EGS. Cognition was assessed using the Montreal Cognitive Assessment (MoCA). Patients were stratified into: CI (MoCA score<26) and no-CI (MoCA≥26). Outcomes were the prevalence of CI, in-hospital complications, discharged to rehab/skilled nursing facility (SNF), and mortality.

RESULTS

A total of 142 patients were enrolled. Overall prevalence of CI was 20%. Patients with CI had higher rates of complications (OR 1.6 [1.4-1.9]; p = 0.01), and discharge to rehab/SNF (OR 2.2 [2.0-2.5]; p = 0.03). There was no difference in mortality (OR 1.1 [0.6-1.8]; p = 0.24) between the 2 groups.

CONCLUSION

One in five geriatric EGS patients has CI. It is associated with higher complications and adverse discharge. Cognitive assessment should be included in preoperative risk stratification.

Prospective Evaluation of Delirium in Geriatric Patients Undergoing Emergency General Surgery

BACKGROUND

The prevalence of delirium and its impact on outcomes after emergency general surgery (EGS) remain unexplored. The aims of our study were to assess the impact of frailty on delirium and the impact of delirium on outcomes in geriatric EGS patients.

STUDY DESIGN

We performed a 1-year (2017) prospective cohort analysis of all geriatric (age ≥ 65 years) patients who underwent EGS. Frailty was calculated using the Emergency General Surgery-Specific Frailty Index (ESFI). Delirium was assessed using the Confusion Assessment Method (CAM). Patients were dichotomized as delirious or non-delirious. We performed regression analysis controlling for demographics, admission vitals, American Society of Anesthesiologists (ASA) score, comorbidity, and the diagnosis and type of surgery.

RESULTS

A total of 163 patients underwent emergency general surgery and were included. Mean age was 71 ± 7 years, and 59% were male. Overall, the incidence of postoperative delirium was 26%. Patients who developed postoperative delirium were more likely to be frail (40% vs 14%, p < 0.01), on more than 3 medications (29% vs 18%, p < 0.01), and were more likely to have 3 or more comorbidities (32% vs 21%, p < 0.01). On regression analysis, frail status (odds ratio [OR] 3.7 [2.4-4.2], p < 0.01) and receiving more than 3 medications (OR 1.3 [range 1.1-1.4], p < 0.01) were independent predictors of developing postoperative delirium. An episode of delirium was associated with longer hospital length of stay (LOS) (6 days vs 3 days, p < 0.01), higher odds of ICU admission (OR 2 [1.3-4.5], p < 0.01), longer ICU LOS (2 days vs 1 day, p < 0.01), and higher odds of unplanned intubation (OR 1.8 [1.2-3.4], p < 0.01).

CONCLUSIONS

The incidence of delirium after EGS was 26%. Frailty and polypharmacy were associated with increased risk of delirium. Delirium appears to be associated with higher rates of in-hospital adverse events.

Contributing factors and short-term surgical outcomes of patients with early-onset rectal cancer

INTRODUCTION

The aim of this study was to evaluate patient factors that contribute to increased incidence of early onset rectal cancer and analyze the short-term surgical outcomes of patients undergoing surgery.

METHODS

A 2-year review (2015-2016) of the ACS-NSQIP included patients with rectal cancer who underwent surgical management. Patients were stratified into early-onset RC (<50-years) and late-onset RC (≥50-years).

RESULTS

We included a total of 7538 patients in the analysis. Overall, 14% of the patients had early-onset RC. Patients with early-onset RC were more likely to be Black and Hispanic. Additionally, they were more likely to present with higher TNM stages. Patients with early-onset RC had lower 30-day complications and lower 30-day mortality. There was no difference between the two groups regarding hospital length of stay or 30-day readmission. On regression analysis, there was no difference between the two groups regarding patient outcomes.

CONCLUSIONS

Racial disparities do exist in the incidence of RC. Young patients tend to have more aggressive disease, however, surgical outcomes between the two groups are comparable.

Pediatric resuscitation: Weight-based packed red blood cell volume is a reliable predictor of mortality

BACKGROUND

The definition of massive transfusion (MT) in civilian pediatric trauma patients is not established. In combat-injured pediatric patients, the definition of MT is based on the volume of total blood products transfused. The aim of this study is to define MT in civilian pediatric trauma patients based on a packed red blood cell (PRBC) volume threshold and compare its predictive power to a total blood products volume threshold.

METHODS

An analysis of the pediatric American College of Surgeons Trauma Quality Improvement Program database was performed (2014-2016) including pediatric trauma patients (4-18 years) who received blood products within 24 hours. Receiver operator characteristic curves for predicting mortality determined the optimal PRBC MT threshold. Area under receiver operating characteristic curve (AUROC) curve analysis was performed to compare the predictive power of a PRBC threshold to a total blood product threshold.

RESULTS

A total of 1,495 patients were included. Sensitivity and specificity for 24-hour and in-hospital mortality were optimal at a PRBC threshold of 20 mL/kg. As compared with total blood products threshold, 20 mL/kg PRBCs volume achieved higher discriminatory power for predicting 24-hour (AUROC, 0.803 vs. 0.672; p < 0.001) and in-hospital mortality (AUROC, 0.815 vs. 0.686, p < 0.001). Patients who received an MT had higher Injury Severity Score (p < 0.001) and were more likely to receive mechanical ventilation (p < 0.001) and intensive care unit admission (p < 0.001). Overall 24-hour mortality (23.1% vs. 7.6%, p < 0.001) and in-hospital mortality (44.9% vs. 15.8%, p < 0.001) were higher in the MT group. On regression analysis, MT significantly predicted in-hospital mortality (odds ratio, 3.8 [2.9-4.9, 95% CI]) and 24-hour mortality (odds ratio, 3.3 [2.4-4.7, 95% CI]).

CONCLUSION

The use of a PRBCs MT definition in civilian pediatric patients is a better predictor of mortality compared with total blood products threshold. These results provide a framework for MT protocol development.

Metabolic Syndrome Exponentially Increases the Risk of Adverse Outcomes in Operative Diverticulitis

BACKGROUND

Metabolic syndrome (MS) is defined as the cluster: hypertension, obesity, and diabetes. Operative diverticulitis in the setting of MS can be challenging to manage. The aim of our study was to evaluate the impact of MS on outcomes in operative acute diverticulitis patients.

METHODS

We analyzed the (2012-2015) NSQIP database. We identified acute diverticulitis patients who underwent surgery. MS was defined as follows: body mass index (BMI) >30 kg/m², hypertension, and diabetes. Our primary outcome measure was the occurrence of any adverse events (complications, 30-d readmission, and mortality). Secondary outcome measures were complications, hospital length of stay, 30-d readmission, and mortality. Regression and receiver operating characteristic curve analysis was performed.

RESULTS

A total of 4572 patients were identified. Mean BMI was 29 ± 10 kg/m². 14.6% (275) of obese patients had metabolic syndrome. Adverse events were higher in patients with MS (odds ratio [OR], 8.1; P < 0.001) versus the obese group and the obese and hypertensive group. Patients with MS had higher odds of reintubation (OR 1.9; P = 0.03), >48 h ventilator dependence (OR 3.5; P = 0.01), myocardial infarction (OR 2.3; P = 0.03), and superficial or deep surgical-site infections (OR 2.1; P = 0.01) compared with patients with no MS. MS patients had a longer length of stay (β = 1.23; P = 0.02), higher 30-d readmissions (OR 1.7; P < 0.01), and mortality (OR 2.1; P < 0.01). The area under the receiver operating characteristic curve of metabolic syndrome for predicting adverse outcomes was 0.797, which was higher than the area under the receiver operating characteristic curve for BMI (0.58), hypertension (0.51), or diabetes (0.64) alone.

CONCLUSIONS

Adverse events in patients with MS after surgery for diverticulitis are higher than obesity, hypertension, or diabetes alone. Patients with MS have longer recovery, and higher rates of complications, readmissions, and mortality.

Preinjury Statins Are Associated With Improved Survival in Patients With Traumatic Brain Injury

BACKGROUND

Statins have been shown to improve outcomes in traumatic brain injury (TBI) in animal models. The aim of our study was to determine the effect of preinjury statins on outcomes in TBI patients.

METHODS

We performed a 4-y (2014-2017) review of our TBI database and included all patients aged ≥18 y with severe isolated TBI. Patients were stratified into those who were on statins and those who were not and were matched (1:2 ratio) using propensity score matching. The primary outcome was in-hospital mortality. The secondary outcomes were skilled nursing facility disposition, Glasgow Outcome Scale-extended score, and hospital and intensive care unit length of stay (LOS).

RESULTS

We identified 1359 patients, of which 270 were matched (statin: 90, no-statin: 180). Mean age was 55 ± 8y, median Glasgow Coma Scale was 10 (8-12), and median head-abbreviated injury scale was 3 (3-5). Matched groups were similar in age, mechanism of injury, Glasgow Coma Scale, Injury Severity Score, neurosurgical intervention, type and size of intracranial hemorrhage, and preinjury anticoagulant or antiplatelet use. The overall in-hospital mortality rate was 18%. Patients who received statins had lower rates of in-hospital mortality (11% versus 21%, P = 0.01), skilled nursing facility disposition (19% versus 28%; P = 0.04), and a higher median Glasgow Outcome Scale-extended (11 [9-13] versus 9 [8-10]; P = 0.04). No differences were found between the two groups in terms of hospital LOS (6 [4-9] versus 5 [3-8]; P = 0.34) and intensive care unit LOS (3 [3-6] versus 4 [3-5]; P = 0.09).

CONCLUSIONS

Preinjury statin use in isolated traumatic brain injury patients is associated with improved outcomes. This finding warrants further investigations to evaluate the potential beneficial role of statins as a therapeutic drug in a TBI.

Chronic Alcohol Consumption and Risk of Deep Venous Thrombosis: A Propensity-Matched Analysis

BACKGROUND

Alcoholism is associated with variable effects on the coagulation system. Therefore, the aim of our study was to analyze the currently unknown association between chronic alcohol consumption and the risk of venous thromboembolism, which includes deep vein thrombosis (DVT) and pulmonary embolism (PE).

METHODS

We performed a 2-y (2013-2014) analysis of the American College of Surgeons Trauma Quality Improvement Program database. All trauma patients with an Injury Severity Score (ISS) > 16 were included. We excluded patients with acute alcohol intoxication, hematologic disorders, and cancer. Patients were divided into two groups (alcoholic and nonalcoholic) and were matched using propensity score matching (1:1) for demographics, ISS, injury location, and admission vitals. Outcomes measures were the prevalence of venous thromboembolism in each group.

RESULTS

Of the 91,066 trauma patients included in our analysis, 35,460 patients were matched (alcoholics: 17,730; nonalcoholics: 17,730). The mean was age 45 ± 18 y, and 81% were males. Matched groups were similar in age (P = 0.32), heart rate (P = 0.31), systolic blood pressure (P = 0.46), location of injury (P = 0.85), ISS (P = 0.76), and Glasgow Coma Scale (P = 0.38). Prevalence of DVT was lower in alcoholics compared with nonalcoholics (2.34% versus 5.12%, P = 0.01). The overall incidence of PE was 1.2%, and there was no difference between the two groups (1.1% versus 1.3%, P = 0.22). Similarly, there was no difference in mortality (14.8% versus 15.4%, P = 0.32) between the groups.

CONCLUSIONS

Chronic alcohol consumption is associated with a low risk of DVT in trauma patients. This association warrants further investigation of the possible physiological effects of alcohol in trauma patients.

Prospective evaluation of health-related quality of life in geriatric trauma patients

BACKGROUND

Frailty is an established predictor of adverse outcomes in geriatric patients. Health-related quality of life (HRQoL) is an important outcome measure among trauma patients. This prospective observational study examined the impact of frailty on health-related quality of life in geriatric trauma patients.

METHODS

We prospectively enrolled geriatric (age ≥65 years) trauma patients. We calculated the frailty index (FI) within 24 hours of admission using the trauma-specific frailty index. Patients were stratified into frail (frailty index ≥0.27) and nonfrail (frailty index <0.27). Health-related quality of life was calculated at discharge and at 30 days (day) after discharge using the RAND Short Form-36 (SF-36). Outcome measures were health-related quality of life at discharge, 30-days postdischarge, and delta health-related quality of life. Regression analysis was performed to control for demographic, vital signs, and injury parameters.

RESULTS

We enrolled 296 patients. The mean age was 75.1 ± 9.8 years, 59% were male, and 81% were white. Frail patients accounted for 34%, and they had a lower health-related quality of life at discharge (366 vs 548, P < .01) and at 30-day postdischarge (393 vs 744, P < .01). Nonfrail patients scored higher in 6 out of 8 domains of health-related quality of life. Nonfrail patients had improved delta health-related quality of life (P < .01), unlike frail patients (P = .11). A linear regression model revealed an inverse relationship between frailty and improvement in health-related quality of life over 30-day postdischarge (β = -0.689, [confidence interval, -0.963 to -0.329] P = .01). This association remained statistically significant after controlling for potential confounding covariates, such as age, sex, race, and injury severity.

CONCLUSION

Compared with nonfrail geriatric trauma patients, those who were frail had poor health-related quality of life at discharge and at 30-day postdischarge. Frailty negatively affects the recovery of health-related quality of life after trauma. The use of frailty indices may help identify and develop targeted interventions to improve health-related quality of life among geriatric trauma patients.
