Characteristics of trauma patients that leave against medical advice: An eight-year survey analysis using the National Hospital Ambulatory Medical Care Survey, 2009–2016

BackgroundLeaving against medical advice (AMA) is associated with increased readmission rates, fragmented patient care, and healthcare litigation. Understanding the factors associated with trauma patients leaving AMA from acute care settings will help guide better communication with trauma patients and improve patient satisfaction. This study aims to assess the sociodemographic and in-hospital care characteristics of trauma patients that leave AMA from acute care centers across the U.S.MethodsWe pooled and analyzed eight years of data (2009–2016) from the National Hospital Ambulatory Medical Care Survey. The outcome variable was whether the patient left AMA or not. The main predictors were the triage class, weekend presentation, health insurance status, the presence of chronic diseases, and the receipt of therapeutic and diagnostic procedures. The sociodemographic characteristics -age, sex, and race/ethnicity, were measured as potential confounders in the developed model. We performed logistic regression and reported the unadjusted and adjusted odds of leaving AMA as well as the 95% confidence intervals.ResultsThe weighted percent of the trauma patient population that left AMA was 1.8%. The odds of leaving AMA decreased with advancing age, and increased among non-Hispanic Blacks, compared with non-Hispanic Whites. After adjusting for age, race, and gender, the odds of leaving AMA increased among patients that lacked health insurance (AOR: 1.86; 95% CI: 1.51–2.31), and had diagnostic procedures (AOR: 2.79; 95% CI: 2.32–3.36). The odds of leaving AMA reduced among trauma patients who were classified as emergent (AOR: 0.70; 95% CI: 0.50–0.98) and had therapeutic procedures (AOR: 0.39; 95% CI: 0.32–0.47).ConclusionPredicting trauma patients with increased odds of leaving AMA will inform intentional communication that may reduce leaving AMA rates and improve care.     

Prolonged Mechanical Ventilation After Lung Transplantation—A Single‐Center Study

This single‐center study examines the incidence, etiology, and outcomes associated with prolonged mechanical ventilation (PMV), defined as time to definite spontaneous ventilation >21 days after double lung transplantation (LTx). A total of 690 LTx recipients between January 2005 and December 2012 were analyzed. PMV was necessary in 95 (13.8%) patients with decreasing incidence during the observation period (p < 0.001). Independent predictors of PMV were renal replacement therapy (odds ratio [OR] 11.13 [95% CI, 5.82–21.29], p < 0.001), anastomotic dehiscence (OR 8.74 [95% CI 2.42–31.58], p = 0.001), autoimmune comorbidity (OR 5.52 [95% CI 1.86–16.41], p = 0.002), and postoperative neurologic complications (OR 5.03 [95% CI 1.98–12.81], p = 0.001), among others. Overall 1‐year survival was 86.0% (90.4% for LTx between 2010 and 2012); it was 60.7% after PMV and 90.0% in controls (p < 0.001). Conditional long‐term outcome among hospital survivors, however, did not differ between the groups (p = 0.78). Multivariate analysis identified renal replacement therapy (hazard ratio [HR] 3.55 [95% CI 2.40–5.25], p < 0.001), post‐LTx extracorporeal membrane oxygenation (HR 3.47 [95% CI 2.06–5.83], p < 0.001), and prolonged inotropic support (HR 1.95 [95% CI 1.39–2.75], p < 0.001), among others, as independent predictors of mortality. In conclusion, PMV complicated 14% of LTx procedures and, although associated with increased in‐hospital mortality, outcomes among patients surviving to hospital discharge were unaffected.     

Does mortality after trauma team activation peak at shift change?

BackgroundPrior institutional data have demonstrated trauma mortality to be highest between 06:00–07:59 at our center, which is also when providers change shifts (07:00–07:30). The objective was definition of patient, provider, and systems variables associated with trauma mortality at shift change among patients arriving as trauma team activations (TTA).MethodsAll TTA patients at our ACS-verified Level I trauma center were included (01/2008–07/2019), excluding those with undocumented arrival time. Study groups were defined by arrival time: shift change (SC) (06:00–07:59) vs. non-shift change (NSC) (all other times). Univariable/multivariable analyses compared key variables. Propensity score analysis compared outcomes after matching.ResultsAfter exclusions, 6020 patients remained: 229 (4%) SC and 5791 (96%) NSC. SC mortality was 25% vs. 16% during NSC (p < 0.001). More SC patients arrived with SBP <90 (19% vs. 11%, p < 0.001) or GCS <9 (35% vs. 24%, p < 0.001). ISS was higher during SC (43[32–50] vs. 34[27–50], p < 0.001). Time to CT scan (36[23–66] vs. 38[23–61] minutes, p = 0.638) and emergent surgery (94[35–141] vs. 63[34–107] minutes, p = 0.071) were comparable. Older age (p < 0.001), SBP <90 (p < 0.001), GCS <9 (p < 0.001), need for emergent operative intervention (p = 0.044), and higher ISS (p < 0.001) were independently associated with mortality. After propensity score matching, mortality was no different between SC and NSC (p = 0.764).ConclusionsEarly morning is a low-volume, high-mortality time for TTAs. Increased mortality at shift change was independently associated with patient/injury factors but not provider/systems factors. Ensuring ample clinical resource allocation during this high acuity time may be prudent to streamline patient care at shift change.     

Breast reconstruction after mastectomy: A ten-year analysis of trends and immediate postoperative outcomes

The landscape of breast reconstruction has changed significantly. This study assesses trends in type of reconstruction performed after mastectomy and impact on immediate postoperative complications.MethodsData for 67,450 patients undergoing mastectomy for breast cancer were analyzed using the National Surgical Quality Improvement Program (NSQIP) database for years 2005-2014. Primary outcomes were wound, nonwound related infections, and bleeding complications. Data were analyzed by univariate and multivariate analysis.ResultsThe percentage of patients that underwent reconstruction after breast cancer increased from 26.94% in 2005 to 43.30% in 2014 (p < 0.01). There was increased wound (5.59%), bleeding (6.82%), and infection (1.80%) complications after flap-based reconstruction (p < 0.01). There was no difference in wound, infection, and bleeding complications between immediate implant reconstruction and tissue expander (TE) at 4.38 vs. 3.89% (p = 0.18), 0.82 vs. 0.7%, p = 0.46), and 0.76 vs. 0.64% (p = 0.45), respectively. Several independent factors were associated with increased wound complications in patients undergoing all or any forms of reconstruction after mastectomy such as being overweight (OR 1.38, CI 1.23–1.55), obese (OR 2.11, CI 1.89–2.35), morbidly obese (OR 3.84, CI 3.34-4.43), ASA Class III (OR 1.35, CI 1.08-1.69), ASA Class IV (OR 1.49, 1.06-2.10), diabetic (OR 1.28 , CI 1.14–1.43), and smokers (OR 1.76, CI 1.59–1.94). TRAM flap was associated with increased risk of wound complication (OR 1.87, CI 1.28–2.75).ConclusionMore women are undergoing reconstruction as utilization of TE increases drastically. Immediate implant placement has only seen moderate increase likely due to surgeon preference.     

Uninsured status may be more predictive of outcomes among the severely injured than minority race

AimWorse outcomes in trauma in the United States have been reported for both the uninsured and minority race. We sought to determine whether disparities would persist among severely injured patients treated at trauma centres where standard triage trauma protocols limit bias from health systems and providers.MethodsWe performed a retrospective analysis of the 2010–2012 National Sample Program from the National Trauma Databank, which is a nationally representative sample of trauma centre performance in the United States. The database was screened for adults ages 18–64 who had a known insurance status. Outcomes measured were in-hospital mortality and post-hospital care.ResultsThere were 739,149 injured patients included in the analysis. Twenty-eight percent were uninsured, and 34 percent were of minority race. In the adjusted analysis, uninsured status (OR 1.60, 1.29–1.98, p < 0.001) and black race (OR 1.24, 1.04–1.49, p = 0.019) were significant predictors of mortality. Only uninsured status was a significant negative predictor of post-hospital care (OR 0.43, 0.36–0.51, p < 0.001). As injury severity increased, only insurance status was a significant predictor of both increased mortality (OR 1.68, 1.29–2.19, p < 0.001) and decreased post-hospital care (OR 0.45, 0.32–0.63, p < 0.001).ConclusionUninsured status is independently associated with higher in-hospital mortality and decreased post-hospital care in patients with severe injuries in a nationally representative sample of trauma centres in the United States. Increased in-hospital mortality is likely due to endogenous patient factors while decreased post-hospital care is likely due to economic constraints. Minority race is less of a factor influencing disparate outcomes among the severely injured.     

Surgical reconstruction of major bile duct injuries: Long-term results and risk factors for restenosis

BackgroundA single-institution retrospective analysis was undertaken to assess long-term results of definitive surgical reconstruction for major bile duct injuries and risk factors for restenosis.MethodsPatients treated between January 1995 and October 2020 were reviewed retrospectively. The primary outcome measure was patency.ResultsOf 417 patients referred to a tertiary center, 290 (69.5%) underwent surgical reconstruction; mostly in the form of a hepaticojejunostomy (n = 281, 96.8%). Major liver resection was undertaken in 18 patients (6.2%). There were 7 postoperative deaths (2.4%). Patency was achieved in 97.4% of primary repairs and 88.8% of re-repairs. Primary patency at three months (including postoperative deaths and stents removed afterwards) in primary repairs was significantly higher than secondary patency attained during the same period in re-repairs (89.3% vs 76.5%, p < 0.01). The actuarial primary patency was also significantly higher compared to the actuarial secondary patency 10 years after reconstruction (86.7% vs 70.4%, p = 0.001). Vascular disruption was the only independent predictor of loss of patency after reconstruction (OR 7.09, 95% CI 3.45–14.49, p < 0.001), showing interaction with injuries at or above the biliary bifurcation (OR 9.52, 95% CI 2.56–33.33, p < 0.001).ConclusionsLong-term outcome of surgical reconstruction for major bile duct injuries was superior in primary repairs compared to re-repairs. Concomitant vascular injury was independently associated with loss of patency requiring revision.     

Management of paediatric splenic injury in the New South Wales trauma system

Since the 1980’s, paediatric surgeons have increasingly managed blunt splenic injury (BSI) in children non-operatively. However, studies in North America have shown higher operation rates in non-paediatric centres and by adult surgeons. This association has not been examined elsewhere.ObjectiveTo investigate the management of BSI in New South Wales (NSW) children, to determine the patient and hospital factors related to the odds of operation. Secondarily, to investigate whether the likelihood of operation varied by year.MethodsChildren age 0–16 admitted to a NSW hospital between July 2000 and December 2011 with a diagnosis of BSI were identified in the NSW Admitted Patient Data Collection, and linked to deaths data from Registry of Births Deaths and Marriages, and Bureau of Statistics. The operation rate was calculated and compared between different hospital types. Univariable analysis was used to determine patient and hospital factors associated with operative management. The difference in the odds of operation between the oldest data (July 2000–December 2005) and most recent (January 2006–December 2011) was also examined. Multivariable logistic regression with stepwise elimination was then performed to determine likelihood of operative management according to hospital category and era, adjusting for potential confounders.Results955 cases were identified, with 101(10.6%) managed operatively. On multivariable analysis, factors associated with operation included age (OR 1.11, 95% CI 1.01–1.18, p < 0.05), massive splenic disruption (OR 3.10, 95% CI 1.61–6.19, p < 0.001), hollow viscus injury (OR 11.03, 95% CI 3.46–34.28, p < 0.001) and transfusion (OR 7.70, 95% CI 4.54–13.16, p < 0.001). Management outside a paediatric trauma centre remained significantly associated with operation, whether it be metropolitan adult trauma centre (OR 4.22 95% CI 1.70–10.52, p < 0.01), rural trauma centre (OR 3.72 95% CI 1.83–7.83, p < 0.001) or metropolitan local hospital (OR 5.23, 95% CI 1.22–18.93 p < 0.05). Comparing the 2 eras, the overall operation rate fell, although not significantly, from 12.9% to 8.7% (OR 1.3, 95% CI 0.89–243 p = 0.13)ConclusionWhile Paediatric Surgeons have wholeheartedly adopted non-operative management, away from paediatric centres, children in NSW are still being operated on for BSI unnecessarily. While the factors at play may be complex, further evaluation of the management and movement of injured children within the broad NSW trauma system is required.     

Trauma recidivism is pervasive and is associated with mental and social health opportunities

IntroductionRecidivism after orthopedic trauma results in greater morbidity and costs. Prior studies explored the effects of social and medical factors affecting the frequency of return to the hospital with new, unrelated injury. Identification of mental, social and other risk factors for trauma recidivism may provide opportunities for mitigation. The purposes of this study are to determine the rates of subsequent, unrelated injury noted among orthopedic trauma patients at a large urban trauma center and to evaluate what patient and injury features are associated with greater rates of trauma recidivism. We hypothesize higher rates of new injuries will be related to ballistic trauma and other forms of assault, alcohol and recreational drug use, unemployment, and unmarried status among our trauma patients.MethodsA series of 954 skeletally mature patients at a level 1 trauma center over a 5 year period were included in the study. All were treated operatively for thoracolumbar, pelvic ring, acetabulum, and/or proximal or shaft femoral fractures from a high energy mechanism. Retrospective review of demographic, injury, medical, and social factors, and subsequent care was performed. Trauma recidivism was defined as returning to the emergency department for treatment of any new injury. A backward stepwise logistic regression statistical analysis was used to identify independent predictors of recidivism.ResultsMean age of all patients was 41.2 years, and 73.2% were male. 136 patients (14.3%) returned with a new injury within a mean of 21 months. These trauma recidivists were more likely to sustain a GSW (22.1% vs 11.4%, p = 0.001). They had higher rates of substance use, including tobacco (57.4% vs 41.8%, p = 0.001) and recreational drugs (50.7% vs 34.4%, p = 0.001), and were less likely to be married (10% vs 25.9%, p<0.001). Mental illness was pervasive, noted in 56.6% of patients with new injury (vs 32.8%, p<0.001). Medicaid insurance was most common in the trauma recidivist population (58.1% vs 35.0%, p = 0.001), and 12.5% were uninsured. Completing high school or more education was protective (93% non-recidivist (vs 79%, p = 0.001). Sixty-nine patients (50.7%) were repeat trauma recidivists within the study period. Independent predictors of new injury included recreational drug use (OR 1.64, p = 0.05) and history of assault due to GSW or other means (OR 1.67, p = 0.05). History of pre-existing mental illness represented the greatest risk factor for trauma recidivism (OR 2.55, p<0.001).DiscussionNew injuries resulting in emergency department presentation after prior orthopedic trauma occurred in 14.3% and were associated with history of assault, lower education, Medicaid insurance, tobacco smoking and recreational drug use. Mental illness was the greatest risk factor. Over half of patients with these additional injuries were repeat trauma recidivists, returning for another new injury within less than 2 years. Awareness of risk factors may promote focused education and other interventions to mitigate this burden.Level of EvidenceLevel 3 retrospective, prognostic     

Should the management approach to the anterior abdominal stab wound be different in patients with self-inflicted abdominal injury?

BackgroundSelf-inflicted injury is a leading cause of death worldwide. It is hypothesized that due to instincts for self-preservation, the severity of abdominal injury would be decreased following suicidal self-stabbing in comparison to stab wounds from assault, and therefore a more conservative management might be considered.MethodsAll patients with isolated abdominal stab wound (SW) admitted to 19 Trauma Centers in Israel between the years 1997 and 2018 were included in the study. Patients with self-inflicted abdominal SW (Group I) were compared to victims with abdominal SW following assault (Group II).ResultsGroup I included 9.4% (314/3324) of patients eligible for this study. Compared to Group II, Group I patients were older (median: 39 years, IQR 28,52 vs. 24 years, IQR 19,33; p<0.001), had more females (28.7% vs 4.9%, p <0.001), had longer length of hospitalization (median: 3 days vs. 2 days; p<0.001), underwent surgery more frequently (55.4% vs. 37.4%; p<0.001), and had higher mortality (2.9% vs. 0.7%; p=0.003). Possible covariates for mortality were examined and following logistic regression, self-inflicted injury remained associated with higher death rates compared to assault (OR 4.027, CI95% 1.380, 11.749; p=0.011).ConclusionIn this study, patients with isolated self-inflicted abdominal injuries had higher mortality and more frequently underwent abdominal surgery.     

Common and contrast determinants of peripheral artery disease and diabetic peripheral neuropathy in North Central Nigeria

BackgroundPeripheral artery disease (PAD) and diabetic peripheral neuropathy (DPN) are two of the leading causes of non-traumatic amputation worldwide with tremendous negative effects on the quality of life, psychosocial well-being of persons with diabetes mellitus; and a great burden on health care expenditure. It is therefore imperative, to identify the common and contrast determinants of PAD and DPN in order to ease adoption of common and specific strategies for their early prevention.MethodsThis was a multi-center cross-sectional study which involved the consecutive enrolment of one thousand and forty (1040) participants following consent and waiver of ethical approval. Relevant medical history, anthropometric measurements, other clinical examinations including measurement of ankle-brachial index (ABI) and neurological examinations were undertaken. IBM SPSS version 23 was used for statistical analysis and logistic regression was used to assess for the common and contrast determinants of PAD and DPN. Significance level used was p < 0.05.ResultsMultiple stepwise logistic regression showed that common predictors of PAD vs DPN respectively include age, odds ratio (OR) 1.51 vs 1.99, 95 % confidence interval (CI) 1.18–2.34 vs 1.35–2.54, p = 0.033 vs 0.003; duration of DM (OR 1.51 vs 2.01, CI 1.23–1.85 vs 1.00–3.02, p = <.001 vs 0.032); central obesity (OR 9.77 vs 1.12, CI 5.07–18.82 vs 1.08–3.25, p = <.001 vs 0.047); poor SBP control (OR 2.47 vs 1.78, CI 1.26–4.87 vs 1.18–3.31, p = .016 vs 0.001); poor DBP control (OR 2.45 vs 1.45, CI 1.24–4.84 vs 1.13–2.59, p = .010 vs 0.006); poor 2HrPP control (OR 3.43 vs 2.83, CI 1.79–6.56 vs 1.31–4.17, p = <.001 vs 0.001); poor HbA1c control (OR 2.59 vs 2.31, CI 1.50–5.71 vs 1.47–3.69, p = <.001 vs 0.004).Common negative predictors or probable protective factors of PAD and DPN respectively include statins (OR 3.01 vs 2.21, CI 1.99–9.19 vs 1.45–3.26, p = .023 vs 0.004); and antiplatelets (OR 7.14 vs 2.46, CI 3.03–15.61 vs 1.09–5.53, p = .008 vs 0.030). However, only DPN was significantly predicted by female gender (OR 1.94, CI 1.39–2.25, p = 0.023), height (OR 2.02, CI 1.85–2.20, p = 0.001), generalized obesity (OR 2.02, CI 1.58–2.79, p = 0.002), and poor FPG control (OR 2.43, CI 1.50–4.10, p = 0.004)ConclusionCommon determinants of PAD and DPN included age, duration of DM, central obesity, and poor control of SBP, DBP, and 2HrPP control. Additionally, the use of antiplatelets and statins use were common inverse determinants of PAD and DPN which means they may help protect against PAD and DPN. However, only DPN was significantly predicted by female gender, height, generalized obesity, and poor control of FPG.     

Impact of diabetes on clinical outcome in severely burned patients

IntroductionAccording to the International Diabetes Federation, approximately 425 million people worldwide suffer from diabetes mellitus, a figure that will double in the next 20 years. Data on the ratio of treated diabetics in burn intensive care units remain scarce and the effects on the mortality rate are poorly defined.MethodsOur retrospective, single-centre study aimed to evaluate differences in the risk factors due to diabetes mellitus, the clinical outcome and the patient population of diabetic patients after severe burn injuries over a time period of 21 years.ResultsDespite increasing numbers of diabetic patients, the ratio of burn patients suffering from diabetes remained stable during the study period. The risk factors for mortality were higher age (OR 1.03, 95% confidence interval (CI), 1.02–1.04, p < 0.0001), female sex (OR 1.56, 95% CI, 1.06–2.29, p = 0.025), higher % total body surface area (TBSA) (OR 3.88, 95% CI, 2.81–5.46, p < 0.0001), full thickness burns (OR 8.58, 95% CI, 3.84 – 23.60, p < 0.0001) and the presence of inhalation injuries (OR 4.68, 95% CI, 3.15–7.02, p < 0.0001) Patients with diabetes had a smaller extent of burned areas with a median TBSA of 30% (quartiles: 22–50%, p = 0.036) compared to non-diabetic patients (35% (25–55%)) but had a similar length of stay with a median of 29 (quartiles: 13–44) days vs. 23 (10–48) days. Outcome analysis showed an overall mortality of 35.6%. Diabetes was not associated with higher mortality rate after burn injury in a univariate model (OR 1.80, 95% CI 0.92–3.51). After correction for %TBSA, the effect of diabetes on mortality was significant (OR 2.80, 95% CI, 1.33–5.90).ConclusionOur data indicate higher mortality rates (50–100%) of diabetic patients with TBSA greater than 40% in severely burned patients compared to non-diabetic patients without a significant outcome due to the low number of cases in the subgroup analyses.     

Differences in sensitivity to neoadjuvant chemotherapy among invasive lobular and ductal carcinoma of the breast and implications on surgery–A systematic review and meta-analysis

Meta-analysis of >87,000 patients demonstrates that patients with invasive lobular carcinoma of the breast are far less likely to achieve pCR of the breast or axilla compared to their ductal counterparts, receive less BCS and more frequently return positive margins.BackgroundNeoadjuvant chemotherapy (NACT) facilitates tumour downstaging, increases breast conserving surgery (BCS) and assesses tumour chemosensitivity. Despite clinicopathological differences in Invasive Ductal Carcinoma (IDC) and Invasive Lobular Carcinoma (ILC), decision making surrounding the use NACT does not take account of histological differences.AimTo determine the impact NACT on pathological complete response (pCR), breast conserving surgery (BCS), margin status and axillary pCR in ILC and IDC.MethodsA systematic review was performed in accordance with the PRISMA guidelines. Studies reporting outcomes among ILC and IDCs following NACT were identified. Dichotomous variables were pooled as odds ratios (ORs) with 95% confidence intervals_(CI) using the Mantel-Haenszel method. P-values <0.05 were statistically significant.Results40 studies including 87,303 (7596 ILC [8.7%]and 79,708 IDC [91.3%]) patients were available for analysis. Mean age at diagnosis was 54.9 vs. 50.9 years for ILC and IDC, respectively. IDCs were significantly more likely to achieve pCR (22.1% v 7.4%, OR: 3.03 [95% CI 2.5–3.68] p < 0.00001), axillary pCR (23.6% vs. 13.4%, OR: 2.01 [95% CI 1.77–2.28] p < 0.00001) and receive BCS (45.7% vs. 33.3%, OR 2.14 [95% CI 1.87–2.45] p < 0.00001) versus ILCs. ILCs were significantly more likely to have positive margins at the time of surgery (36% vs 13.5%, OR 4.84 [95% CI 2.88–8.15] p < 0.00001).ConclusionThis is the largest study comparing the impact of NACT among ILC and IDC with respect to pCR and BCS. ILC has different outcomes to IDC following NACT and incorporate it into treatment decisions and future clinical guidelines.     

Insurance status is associated with urgent carotid endarterectomy and worse postoperative outcomes

ObjectiveUnderinsured patients can experience worse preoperative medical optimization. We aimed to determine whether insurance status was associated with carotid endarterectomy (CEA) urgency and postoperative outcomes.MethodsWe analyzed the Society for Vascular Surgery Vascular Quality Initiative Carotid Endarterectomy dataset from January 2012 to January 2021. Univariable and multivariable methods were used to analyze the differences across the insurance types for the primary outcome variable: CEA urgency. The analyses were limited to patients aged <65 years to minimize age confounding across insurers. We also examined differences in preoperative medical optimization and symptomatic disease and postoperative outcomes. A secondary analysis was performed to examine the effect of CEA urgency on the postoperative outcomes.ResultsA total of 27,331 patients had undergone first-time CEA. Of these patients, 4600 (17%) had Medicare, 3440 (13%) had Medicaid, 17,917 (65%) had commercial insurance, and 1374 (5%) were uninsured. The Medicaid and uninsured patients had higher rates of urgent operation compared with Medicare (20.0% and 34.7% vs 14.4%; P < .001), with no differences in the commercial group vs the Medicare group. Additionally, Medicaid and uninsured patients had lower rates of aspirin, statin, and/or antiplatelet use (93.6% and 93.5% vs 95.8%; P < .001) and higher rates of symptomatic disease (42.1% and 57.6% vs 36.2%; P < .001) compared with Medicare patients. The rate of perioperative stroke/death was higher for the Medicaid and uninsured patients than for the Medicare patients (1.63% and 1.89% vs 1.02%; P = .017 and P = .01, respectively), with no differences in the commercial group. Multivariable analysis demonstrated that compared with Medicare, Medicaid and uninsured status were associated with increased odds of an urgent operation (odds ratio [OR], 1.3; 95% confidence interval [CI], 1.1-1.5; and OR, 2.3; 95% CI, 2.0-2.7, respectively), symptomatic disease (OR, 1.2; 95% CI, 1.1-1.4; and OR, 2.2; 95% CI, 1.9-2.5, respectively), and perioperative stroke/death (OR, 1.6; 95% CI, 1.1-2.4; and OR, 1.8; 95% CI, 1.1-3.0, respectively) and a decreased odds of aspirin, statin, and/or antiplatelet use (OR, 0.71; 95% CI, 0.6-0.9; and OR, 0.76; 95% CI, 0.6-0.99, respectively). Additionally, the rates of perioperative stroke/death were higher for patients who had required urgent surgery compared with elective surgery (2.8% vs 1.0%; P < .001). Multivariable analysis demonstrated increased odds of perioperative stroke/death for patients who had required urgent surgery (OR, 2.4; 95% CI, 1.9-3.1).ConclusionsMedicaid and uninsured patients were more likely to require urgent CEA, in part because of poor preoperative medical optimization. Additionally, urgent operation was independently associated with worse postoperative outcomes. These results highlight the need for improved preoperative follow-up for underinsured populations.     

Trauma patients with tibia/fibula fractures are associated with an increased risk of torso,severe head,and severe spine injuries compared to patients with femur fractures

BackgroundAlthough previous studies have demonstrated an association between lower extremity fractures and concomitant torso (thorax and abdomen) injuries in trauma patients, they do not compare different types of fractures. Therefore, we investigated the risk of associated torso injuries between femur and tibia/fibula fractures, hypothesizing that trauma patients with femur fractures are at higher risk of torso injuries compared to patients with tibia/fibula fractures.MethodsThe Trauma Quality Improvement Program database (2010-2016) was queried for patients presenting with either femur or tibia/fibula fractures. Patients with ground-level falls and penetrating injuries were excluded. Univariable and multivariable logistic regression analyses were performed.ResultsFrom 162,354 patients, 104,075 (64.1%) patients had femur fractures and 58,279 (35.9%) had tibia/fibula fractures. Compared to those with femur fractures, patients with tibia/fibula fractures had a higher incidence of torso injuries (32.2% vs. 17.7%, p<0.001). The tibia/fibula fracture group was also associated with an increased risk of torso (OR 2.22, CI 2.17-2.27, p<0.001), severe (abbreviated injury scale grade > 3) head (OR 2.38, CI 2.30-2.46, p<0.001), and severe spine injuries (OR 2.33, CI 2.07-2.62, p<0.001) compared to the femur fracture group. Additionally, patients with tibia/fibula fractures had a higher rate of deep vein thrombosis (2.5% vs. 1.8%, p<0.001) than patients with femur fractures.ConclusionsContrary to previous studies, we demonstrate patients with tibia/fibula fractures have a higher associated risk of torso, severe head and severe spine injuries than patients with femur fractures. Therefore, trauma surgeons should manage tibia/fibula fracture patients with similar clinical vigilance as femur fracture patients.     

Opioid use disorder in adult burn patients: Implications for future mental health,behavioral and substance use patterns

BackgroundBurn patients continue to have a high opioid requirement, despite current national trends to decrease opioid prescribing. While effective, long-term opioid use results in opioid dependence and possibly other mental health comorbidities. This retrospective cohort study seeks to evaluate implications of diagnosed opioid use disorder in the development of subsequent psychiatric, behavioral and substance abuse patterns.MethodsThe TriNetX database was queried for patients 18 years and older with a diagnosis of thermal or chemical burn who developed opioid use disorder after their burn injury. Two matched cohorts were studied, opioid use disorder versus non-opioid use disorder, to evaluate risk of developing subsequent mental health and behavioral conditions, use of psychiatric health services, and future substance abuse.ResultsA total of 2020 patients were identified in each cohort, matched for demographics, external trauma, and burn size. Patients in the opioid use disorder group had a significantly higher incidence of mental health diagnoses (79.7 % versus 57.7 %, OR 1.973, CI 1.741–2.236, p < 0.0001), including major depressive disorder, generalized anxiety disorder, and post-traumatic stress disorder. This group was also more likely to utilize psychiatric services (16.0 % versus 10.3 %, OR 1.926, CI 1.595–2.326, p < 0.0001) and psychotherapy (12.6 % versus 7.2 %, OR 2.046, CI 1.650–2.536, p<0.0001). Furthermore, the opioid use disorder group had higher rates of polysubstance abuse (29.9 % versus 12.3 %, OR 3.048, CI 2.588–3.589, p<0.0001), suicidal / homicidal ideations (8.2 % versus 3.2 %, OR 3.057, CI 2.274–4.109, p<0.0001), and suicide attempts (2.0 % versus 0.7 %, OR 2.971, CI 1.611–5.478, p = 0.003).ConclusionsBurn patients who develop opioid use disorder have significantly higher rates of future psychiatric diagnoses, behavioral disturbances, and polysubstance abuse. A multidisciplinary team approach, including early involvement of pain and mental health services, could potentially reduce the development of opioid use disorder and its consequences.     

A multicenter study analyzing the association of vitamin D deficiency and replacement with infectious outcomes in patients with burn injuries

Vitamin D (25OHD) deficiency is associated with poor outcomes in intensive care populations. The primary objective of this 7-center study was to determine if 25OHD deficiency is associated with infectious outcomes in adult burn patients. Generalized linear mixed modeling was used to control for center effect, percent total body surface area burn (% TBSA), age, and presence of inhalation injury. A total of 1147 patients were initially included (admitted January 2016 through August 2019). After exclusions, 234 (56.8%) in the deficient (25OHD<20 ng/mL) and 178 in the non-deficient group (25OHD ≥ 20 ng/mL) remained, surpassing a priori power requirements. The non-deficient group had their concentration drawn earlier (p < 0.001), were more likely to be male (p = 0.006), Caucasian (p < 0.001), have lower body mass index (p = 0.009), lower % TBSA (p = 0.002), and taking a 25OHD supplement prior to admission (p < 0.001). Deficient patients were more likely to have an infectious outcome (52.1% vs 36.0%, p = 0.002), acute kidney injury with renal replacement therapy (p = 0.009), less ventilator free days in the first 28 days (p < 0.001), and vasopressors (p = 0.01). After controlling for center, % TBSA, age, and inhalation injury the best model also included presence of deficiency (OR 2.425 [CI 1.206–4.876]), days until 25OHD supplement initiation (OR 1.139 [CI 1.035–1.252]), and choice of cholecalciferol over ergocalciferol (OR 2.112 [CI 1.151–3.877]). To the authors' knowledge, this is the first multicenter study to evaluate the relationship between 25OHD and infectious complications in burn patients.     

Factors associated with receiving anti-osteoporosis treatment among older persons with minimal trauma hip fracture presenting to an acute orthogeriatric service

Background/AimThe aim of this study was to investigate factors that were associated with receiving anti-osteoporosis treatment (AOT) among patients with minimal trauma hip fracture admitted to an Australian tertiary trauma centre under the Acute Orthogeriatric Service (AOS) over a 6 month period.DesignObservational study using prospectively collected data.MethodsDemographic and clinical characteristics of 211 patients were extracted from the local hip fracture registry and electronic medical records. The outcome measure was receipt of AOT before separation from the AOS. Binary logistic regression was used to identify factors independently associated with treatment.Results91 (45%) patients received AOT, including 51 (25.2%) treatment-naive patients. Factors significantly associated with receiving treatment included higher serum vitamin D level (OR 1.44, 95% CI 1.23–1.70, p < 0.001) and trochanteric vs. cervical fracture (OR 2.67, 95% CI 1.30–5.49, p = 0.007). Living in a residential aged care facility (RACF) prior to the index fracture (OR 0.2, 95% CI 0.08–0.54, p = 0.001) and higher American Society of Anaesthesiologists (ASA) physical status score (OR 0.5, 95% CI 0.25–0.98, p = 0.04) significantly lowered the likelihood of treatment. Age, gender, cognitive impairment, premorbid walking ability, previous fragility fracture and renal impairment did not correlate with treatment.ConclusionA significant proportion (55%) of hip fracture patients did not receive AOT in hospital. The probability of receiving treatment appears to be significantly associated with serum vitamin D level, fracture type, place of residence and comorbidity burden.     

Pediatric Pedestrian Injuries: Striking Too Close to Home

BackgroundPediatric pedestrian injuries (PPI) are a major public health concern. This study utilized geospatial analysis to characterize the risk and injury severity of PPI.MethodsA retrospective chart review of PPI patients (age < 18) from a level 1 trauma center was performed (2013–2020). A geographic information system geocoded injury location to home and other public landmarks. Incidents were aggregated to zip codes and the Local Indicators of Spatial Association statistic tested for spatial clustering of injury rates per 10,000 children. Predictors for increased injury severity were assessed by logistic regression.ResultsPPI encompassed 6% (n = 188) of pediatric traumas. Most patients were black (54%), male (58%), >13 years (56%), and with Medicaid insurance (68%). Nine zip codes comprised a statistically significant cluster of PPI. Nearly half (40%) occurred within a quarter mile of home; 7% occurred at home. Most (65%) PPI occurred within 1 mile of a school, and 45% occurred within a quarter mile of a park. Nearly all (99%) PPI occurred within a quarter mile of a major intersection and/or roadway. Using admission to ICU as a marker for injury severity, farther distance from home (OR 1.060, 95% CI 1.001–1.121, p = 0.045) and age <13 years (3.662, 95% CI 1.854–7.231, p < 0.001) were independent predictors of injury severity.ConclusionsThere are significant sociodemographic disparities in PPI. Most injuries occur near patients’ homes and other public landmarks. Multidisciplinary injury prevention collaboration can help inform policymakers, direct local safety programs, and provide a model for PPI prevention at the national level.Level of EvidenceLevel IV.     

Factors influencing short‐ and long‐term mortality after lower limb amputation

Mortality after lower limb amputation is high, with UK 30‐day mortality rates of 9–17%. We performed a retrospective analysis of factors affecting early and late outcome after lower limb amputation for peripheral vascular disease or diabetic complications at a UK tertiary referral vascular centre between 2003 and 2010. Three hundred and thirty‐nine patients (233 male), of median (IQR [range]) age 73 (62–79 [26–92]) years underwent amputation. Thirty‐day mortality was 12.4%. On regression modelling, the risk of 30‐day mortality was increased in patients of ASA grade ≥ 4 (OR 4.23, 95% CI 2.07–8.63), p < 0.001 and age between 74 and 79 years (OR 3.8, 95% CI 1.10–13.13), p = 0.04 and older than 79 years (OR 4.08, 95% CI 1.25–13.25), p = 0.02. Peri‐operative (30‐day) mortality for these groups was 23.2%, 13.7% and 18.8%, respectively. Survival and Cox regression analysis demonstrated that long‐term mortality was associated with: age 74–79 years (HR 2.15, 95% CI 1.38–3.35), p = 0.001; age > 79 years (HR 2.78, 95% CI 1.82–4.25), p < 0.001; ASA grade ≥ 4 (HR 2.04, 95% CI 1.51–2.75), p < 0.001; out‐of‐hours operating (HR 1.51, 95% CI 1.08–2.10), p = 0.02; and chronic kidney disease stage 4–5 (1.57, 95% CI 1.07–2.30), p = 0.02. Anaesthetic technique was associated with long‐term mortality on survival analysis (p = 0.04), but not when analysed using regression modelling. Mortality after lower limb amputation relates to patient age, ASA, out‐of‐hours surgery and renal dysfunction. These data support lower limb amputations’ being performed during daytime hours and after modification of correctable risk factors.     

Risk factors and effect of postoperative delirium on adverse surgical outcomes in older adults after elective abdominal cancer surgery in Taiwan

BackgroundPostoperative delirium (POD) is a common complication in older adults, with unknown epidemiology and effects on surgical outcomes in Asian geriatric cancer patients. This study evaluated incidence, risk factors, and association between adverse surgical outcomes and POD after intra-abdominal cancer surgery in Taiwan.MethodsOverall, 345 patients aged ≥65 years who underwent elective abdominal cancer surgery at a medical center in Taiwan were prospectively enrolled. Delirium was assessed daily using the Confusion Assessment Method. Univariate and multivariate logistic regression analyses investigated risk factors for POD occurrence and estimated the association with adverse surgical outcomes.ResultsPOD occurred in 19 (5.5%) of the 345 patients. Age ≥73 years, Charlson comorbidity index ≥3, and operative time >428 min were independent predictors for POD occurrence. Patients presenting with one, two, and three risk factors had 4.1-fold (95% confidence interval [CI], 0.4–35.8, p = 0.20), 17.4-fold (95% CI, 2.2–138, p = 0.007), and 30.8-fold likelihood (95% CI, 2.9–321, p = 0.004) for POD occurrence, respectively. Patients with POD had a higher probability of prolonged hospital stay (adjusted odds ratio [OR] 2.8; 95% CI, 1.0–8.1; p = 0.037), intensive care stay (adjusted OR: 3.9; 95% CI, 1.5–10.5; p = 0.008), 30-day readmission (adjusted OR 3.1; 95% CI, 1.1–9.7; p = 0.039), and 90-day postoperative death (adjusted OR: 4.2; 95% CI, 1.0–17.7; p = 0.041).ConclusionPOD occurrence was significantly associated with adverse surgical outcomes in geriatric patients undergoing elective abdominal cancer surgery, highlighting the importance of early POD identification in geriatric patients to improve postoperative care quality.
