RESUMEN

BACKGROUND: Thoracic epidural catheters (TECs) are useful adjuncts to multimodal pain regimens in traumatic rib fractures. However, TEC placement is limited by contraindications, patient risk profile, and provider availability. Continuous peripheral infusion of ketamine and/or lidocaine is an alternative that has a modest risk profile and few contraindications. We hypothesized that patients with multiple traumatic rib fractures receiving TECs would have better pain control, in terms of daily morphine milligram equivalents (MMEs) and mean pain scores (MPSs) when compared with continuous peripheral infusions of ketamine and/or lidocaine. METHODS: We retrospectively analyzed traumatic rib fracture admissions to a level 1 trauma center between January 2018 and December 2020. We evaluated two treatment groups: TEC only and continuous infusion only (drip only). A linear mixed-effects model evaluated the association of MME with treatment group. An interaction term of treatment group by time (days 1-7) was included to allow estimating potential time-dependent treatment effect on MME. A zero-inflated Poisson mixed-effects model evaluated the association of treatment with MPS. Both models adjusted for confounders. RESULTS: A total of 1,647 patients were included. After multivariable analysis, a significant, time-varying dose-response relationship between treatment group and MME was found, indicating an opioid-sparing effect favoring the TEC-only group. The opioid-sparing benefit for TEC-only therapy was most prominent at day 3 (27.4 vs 36.5 MME) and day 4 (27.3 vs 36.2 MME) (p < 0.01). The drip-only group had 1.21 times greater MPS than patients with TEC only (p < 0.001). CONCLUSION: Drip-only analgesia is associated with higher daily MME use and MPS, compared with TEC only. The maximal benefit of TEC therapy appears to be on days 3 and 4. Prospective, randomized comparison between groups is necessary to evaluate the magnitude of the treatment effect.

RESUMEN

INTRODUCTION: The AUA recommends delayed-phase imaging (DPI) in renal injuries to evaluate the collecting system. A renal trauma imaging protocol for early conservative management of urinary extravasation (UE) was implemented to improve guideline adherence. We aimed to determine if increased adherence led to changes in outcomes. METHODS: Patients with American Association for the Surgery of Trauma III to V renal injury presenting from January 2018 to September 2022 were identified from an institutional trauma registry. Patients were included if a contrasted CT scan of the abdomen was obtained on admission. Frequency of DPI and patient outcomes were compared before and after protocol implementation. RESULTS: Of 223 included patients, 131 (58.7%) were pre protocol and 92 (41.3%) were post protocol. Following protocol implementation, the rate of DPI on admission nearly doubled from 32.8% to 58.7% (P < .001). The rate of follow-up cross-sectional imaging increased from 18.3% to 58.7% (P < .001). Although there were no significant differences in rates of immediate or delayed interventions following protocol implementation, the postprotocol immediate intervention rate did decrease to 0%. Readmissions due to symptomatic UE were unchanged after protocol implementation (0.0% vs 0.0%). CONCLUSIONS: Implementation of a multidisciplinary renal trauma early imaging and management protocol improved AUA guideline adherence. With protocol adherence, there was also an elimination of immediate interventions for UE. Despite decreases in early intervention, there was no significant increase in interval interventions or UE-related readmissions. More research is needed to determine the role for routine follow-up imaging in conservative management of high-grade renal trauma.

RESUMEN

Guidelines provide varying recommendations for the prophylactic antimicrobial treatment of open fractures. This single-center, retrospective cohort study was conducted to determine how well an institutional prophylactic antibiotic protocol covered pathogens associated with open fractures. The authors included adult trauma patients with one or more open fractures and a positive culture from the site of the open fracture, and compared outcomes between patients who were covered by prophylactic antibiotics with patients not covered by prophylactic antibiotics. Of 957 patients evaluated, 75 were included, with 40 patients (53%) covered by the prophylactic antibiotics received. Multidrug-resistant pathogens were isolated in 23 (58%) patients covered versus 26 (74%) patients not covered (p = 0.128). The median time to positive culture was less in patients not covered by initial antibiotics compared with those who were covered (30.2 vs. 102.1 days; p = 0.003). Over half of the patients developed cultures with pathogens that were covered by their initial antibiotic prophylaxis. (Journal of Surgical Orthopaedic Advances 33(2):084-087, 2024).

RESUMEN

BACKGROUND: Partial occlusion of the aorta is a resuscitation technique designed to maximize proximal perfusion while allowing a graduated amount of distal flow to reduce the ischemic sequelae associated with complete aortic occlusion. The pREBOA catheter affords the ability to titrate perfusion as hemodynamics allows, however, the impact of this new technology for REBOA on blood use and other resuscitative requirements is currently unknown. We hypothesize pREBOA's ability to provide partial occlusion, when appropriate, decreases overall resuscitative requirements when compared to ER-REBOA. METHODS: The entire AAST AORTA Registry was used to compare resuscitation requirements between all ER-REBOA and pREBOA. Unpaired t-tests were used to compare resuscitation strategies including packed red blood cells (PRBCs), fresh frozen plasma (FFP), platelets, cryoprecipitate, crystalloids, and need for pressors. RESULTS: When comparing ER-REBOA (n=800) use to pREBOA (n=155), initial patient presentations were similar except for age (44 vs 40 p=0.026) and rates of blunt injury (78.4% vs 78.7% p<0.010). Zone-1 occlusion was used less often in ER-REBOA (65.8 vs 71.7 p=0.046). Partial occlusion was performed in 85% of pREBOA compared to 11% in ER-REBOA (p<0.050). Vitals at the time of REBOA were worse in ER-REBOA, and received significantly more units of PRBCs, FFP, platelets, and liters of crystalloids than pREBOA (p<0.05). Rates of ARDS and septic shock were lower in pREBOA (p<0.05). CONCLUSION: When comparing pREBOA to ER-REBOA, there has been a rise in Zone-1 and partial occlusion. In our pilot analysis of the AORTA Registry, there was a reduction in administration of pRBC, FFP, platelets, and crystalloids. Though further prospective studies are required, this is the first to demonstrate an association between pREBOA, partial occlusion, and reduced blood use and resuscitative requirements.

RESUMEN

BACKGROUND: Laparoscopic subtotal cholecystectomy (SC) is used for the difficult cholecystectomy, but published experience with resource use for SC is limited. We hypothesized that the need for advanced resources are common after SC. STUDY DESIGN: This was a retrospective review of laparoscopic cholecystectomies between 2017 and 2021 at a large center. SC cases were identified using a medical record tool. Baseline characteristics were assessed with Student's t -test and chi-square test. Primary outcome was endoscopic retrograde cholangiography (ERC) within 60 days. Secondary outcomes were reconstituted SC on postoperative ERC and length of stay (LOS). Uni- and multivariable logistic regression were used for binary outcomes. Multiple linear regression was used for LOS. Covariates included were age, sex, BMI, and American Society of Anesthesiology class. RESULTS: A total of 1,222 laparoscopic cholecystectomies were performed between 2017 and 2021. Of these, 87 (7%) were SC. Male (p < 0.001) and older (p < 0.001) patients were more likely to undergo SC. Odds of postoperative ERC were higher in the SC group (odds ratio 9.79, 95% CI 5.90 to16.23, p < 0.001). There was no difference in preoperative ERC (17% vs 21%, p = 0.38). Reconstituting SC had lower odds of postoperative ERC (odds ratio 0.12, 95% CI 0.023 to 0.58, p = 0.009). LOS was 1.81 times higher in the SC group (p ≤ 0.001). Postoperative ERC was not associated with LOS (p = 0.24). CONCLUSIONS: We present one of the largest single-center series of SC. Patients who underwent SC are more likely to be male, older, have higher American Society of Anesthesiology class, and have increased LOS. SC should be performed when access to ERC and interventional radiology is available. In the absence of these adjuncts, reconstituting SC decreases the need for early ERC, but long-term outcomes are unknown.

RESUMEN

BACKGROUND: Rapidly localizing and controlling bleeding is central to treating hemorrhagic shock. While REBOA allows temporary control, identifying the source of bleeding remains challenging. CT imaging with REBOA in place may provide information to direct hemorrhage control. The purpose of this study is to provide a descriptive summary of data comparing patients who did and did not undergo CT scan following REBOA deployment. Our hypothesis was that performing CT scan after REBOA placement in select patients is safe and can guide management of hemorrhagic shock. METHODS: We queried the AAST AORTA registry for patients receiving REBOA at our level 1 trauma center from May 2017 to December 2021. Clinical data was obtained through the Trauma Registry of the American College of Surgeons (TRACS). Comparison groups were those who underwent CT scan after REBOA deployment versus those who did not undergo CT scan after REBOA deployment. The primary outcome was inhospital mortality, and secondary outcomes included hospital-, ICU-, and ventilator-free days. RESULTS: 61 patients underwent CT scan with REBOA in place; 25 patients proceeded directly to hemorrhage control. Patients with REBOA prior to CT were more likely to have blunt mechanism, higher ISS, pelvic bleeding, and zone 3 REBOA placement. Mortality was not significantly different (51 % vs. 64 %). Patients who underwent CT with REBOA were more likely to undergo hemorrhage control in interventional radiology (43 % vs. 0 %). There was no difference in hospital-, ICU-, and ventilator-free days. DISCUSSION: We demonstrate the feasibility of performing CT in select trauma patients who undergo REBOA. We describe a pathway to enable expeditious workup and management of these patients. Optimal hemorrhage control management is impacted by CT scans when it can be performed. It is important to note that this is a severely injured patient population, and mortality is high even when hemorrhage is controlled. LEVEL OF EVIDENCE: III.

RESUMEN

BACKGROUND: Prehospital tourniquet use is now standard in trauma patients with diagnosed or suspected extremity vascular injuries. Tourniquet-related vasospasm is an understudied phenomenon that may confound management by causing erroneous arterial pressure indices (APIs) and abnormalities on computed tomography angiography (CTA) that do not reflect true arterial injuries. We hypothesized that shorter intervals between tourniquet removal and CTA imaging and longer total tourniquet times would be correlated with a higher likelihood of false positive CTA. MATERIALS AND METHODS: We performed a single-institution retrospective cohort study of patients presenting to a busy, urban Level 1 Trauma Center with prehospital tourniquets from 2019 to 2021. Patients who presented with a tourniquet disengaged upon arrival or who died prior to admission to the Trauma Unit were excluded. Tourniquet duration, time between tourniquet removal and CTA imaging (CTA interval), CTA findings, and management of extremity arterial injuries were extracted. The proportion of false positive injuries on CTA was assessed for correlation with increasing time interval from tourniquet removal to CTA imaging and correlation with increasing total tourniquet time using multivariable logistic regression. RESULTS: 251 patients were identified with prehospital tourniquets. 127 underwent CTA of the affected extremity, 96 patients had an abnormal CTA finding, and 57 (45% of total CTA patients) had false positive arterial injuries on imaging. Using multivariable logistic regression, neither the CTA interval nor the tourniquet duration was associated with false positive CTA injuries. Female sex was associated with false positive injuries on CTA (OR 2.91, 95% CI: 1.01 - 8.39). Vasospasm was cited as a possible explanation by radiologists in 40% of false positive CTA reports. CONCLUSIONS: Arterial vasospasm is a frequent finding on CTA after tourniquet use for extremity trauma, but concerns regarding tourniquet-related vasospasm should not alter trauma patient management. Neither the duration of tourniquet application nor the time interval since removal is associated with decreased CTA accuracy, and any delay in imaging does not appear to reduce the likelihood of vasospasm. These findings are important for supporting expedited care of trauma patients with severe extremity injuries.

RESUMEN

BACKGROUND: Alcohol withdrawal syndrome (AWS) is associated with increased morbidity and mortality in the trauma population. Benzodiazepines (BZDs) are standard of care for AWS; however, given the risk of delirium with BZDs and reports of BZD-refractory withdrawal, phenobarbital (PHB) has emerged as an alternative therapy for AWS. Safety and efficacy studies of PHB for AWS in trauma patients are lacking. Our aim was to compare a BZD versus PHB protocol in the management of AWS in trauma patients. METHODS: We performed a retrospective cohort study at a level 1 trauma center of patients at risk for AWS managed with either a BZD or a low-dose oral PHB regimen. Patients were excluded if they were taking BZDs or barbiturates before admission, received propofol or dexmedetomidine before initiation of the study drug, presented with delirium tremens or seizures, or died or discharged within 24 hours of presentation. The primary outcome was complicated AWS (seizures or alcohol withdrawal delirium/delirium tremens). Secondary outcomes included uncomplicated AWS; therapy escalation; oversedation; delirium-, intensive care unit-, and ventilator-free days; and length of stay. RESULTS: A total of 411 patients were identified; 118 received BZD, and 293 received PHB. The odds of developing complicated AWS with PHB versus BZD-based therapy were not statistically significant (odds ratio [OR], 0.52; 95% confidence interval [CI], 0.21-1.39); however, patients receiving PHB were less likely to develop uncomplicated AWS (OR, 0.08; 95% CI, 0.04-0.14) and less likely to require escalation of therapy (OR, 0.45; 95% CI, 0.24-0.84). The PHB group had a length of stay 3.1 days shorter than the BZD group ( p = 0.002). There was no difference in intensive care unit-, ventilator-, or delirium-free days. CONCLUSION: A PHB-based protocol for the management of AWS is a safe and effective alternative to BZD-based regimens in trauma patients. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

RESUMEN

BACKGROUND: The use of Zone 1 REBOA for life-threatening trauma has increased dramatically. STUDY DESIGN: The Aortic Occlusion for Resuscitation in Trauma and Acute Care Surgery database was queried for blunt and penetrating trauma between 2013 and 2021. Outcomes were examined both for mechanisms of injury combined and separately and for combinations of abdominal injury with and without traumatic brain injury and chest injuries (Abbreviated Injury Scale [AIS] score >2). RESULTS: A total of 531 patients underwent REBOA (408 with blunt injury and 123 with penetrating injury) and 1,603 (595 with blunt injury and 1,008 with penetrating injury) underwent resuscitative thoracotomy (RT). Mean age was 38.5 ± 16 years and mean injury severity score was 34.5 ± 21; 57.7% had chest AIS score of more than 2, 21.8% had head AIS score of more than 2, and 37.3% had abdominal AIS score of more than 2. Admission Glasgow Coma Scale was 4.9 + 4, and systolic blood pressure at aortic occlusion (AO) was 22 + 40 mmHg. No differences in outcomes in REBOA or RT patients were identified between institutions (p > 0.5). After inverse probability weighting, Glasgow Coma Scale, age, injury severity score, systolic blood pressure at AO, CPR at AO, and blood product transfusion, REBOA was superior to RT in both blunt (odds ratio [OR] 4.7, 95% CI 1.9 to 11.7) and penetrating (OR 4.9, 95% CI 1.7 to 14) injuries, across all spectrums of injury (p < 0.01). Overall mortality was significantly higher for AO more than 90 minutes compared with less than 30 minutes in blunt (OR 4.6, 95% CI 1.5 to 15) and penetrating (OR 5.4, 95% CI 1.1 to 25) injuries. Duration of AO more than 60 minutes was significantly associated with mortality after penetrating abdominal injury (OR 5.1, 95% CI 1.1 to 22) and abdomen and head (OR 5.3, 95% CI 1.6 to 18). CONCLUSIONS: In-hospital survival is higher for patients undergoing REBOA than RT for all injury patterns. Complete AO by REBOA or RT should be limited to less than 30 minutes. Neither hospital and procedure volume nor trauma verification level impacts outcomes for REBOA or RT.

RESUMEN

Importance: Cefepime and piperacillin-tazobactam are commonly administered to hospitalized adults for empirical treatment of infection. Although piperacillin-tazobactam has been hypothesized to cause acute kidney injury and cefepime has been hypothesized to cause neurological dysfunction, their comparative safety has not been evaluated in a randomized clinical trial. Objective: To determine whether the choice between cefepime and piperacillin-tazobactam affects the risks of acute kidney injury or neurological dysfunction. Design, Setting, and Participants: The Antibiotic Choice on Renal Outcomes (ACORN) randomized clinical trial compared cefepime vs piperacillin-tazobactam in adults for whom a clinician initiated an order for antipseudomonal antibiotics within 12 hours of presentation to the hospital in the emergency department or medical intensive care unit at an academic medical center in the US between November 10, 2021, and October 7, 2022. The final date of follow-up was November 4, 2022. Interventions: Patients were randomized in a 1:1 ratio to cefepime or piperacillin-tazobactam. Main Outcomes and Measures: The primary outcome was the highest stage of acute kidney injury or death by day 14, measured on a 5-level ordinal scale ranging from no acute kidney injury to death. The 2 secondary outcomes were the incidence of major adverse kidney events at day 14 and the number of days alive and free of delirium and coma within 14 days. Results: There were 2511 patients included in the primary analysis (median age, 58 years [IQR, 43-69 years]; 42.7% were female; 16.3% were Non-Hispanic Black; 5.4% were Hispanic; 94.7% were enrolled in the emergency department; and 77.2% were receiving vancomycin at enrollment). The highest stage of acute kidney injury or death was not significantly different between the cefepime group and the piperacillin-tazobactam group; there were 85 patients (n = 1214; 7.0%) in the cefepime group with stage 3 acute kidney injury and 92 (7.6%) who died vs 97 patients (n = 1297; 7.5%) in the piperacillin-tazobactam group with stage 3 acute kidney injury and 78 (6.0%) who died (odds ratio, 0.95 [95% CI, 0.80 to 1.13], P = .56). The incidence of major adverse kidney events at day 14 did not differ between groups (124 patients [10.2%] in the cefepime group vs 114 patients [8.8%] in the piperacillin-tazobactam group; absolute difference, 1.4% [95% CI, -1.0% to 3.8%]). Patients in the cefepime group experienced fewer days alive and free of delirium and coma within 14 days (mean [SD], 11.9 [4.6] days vs 12.2 [4.3] days in the piperacillin-tazobactam group; odds ratio, 0.79 [95% CI, 0.65 to 0.95]). Conclusions and Relevance: Among hospitalized adults in this randomized clinical trial, treatment with piperacillin-tazobactam did not increase the incidence of acute kidney injury or death. Treatment with cefepime resulted in more neurological dysfunction. Trial Registration: ClinicalTrials.gov Identifier: NCT05094154.

RESUMEN

INTRODUCTION: Tranexamic acid (TXA) use has been associated with thrombotic complications. OBJECTIVE: We aim to investigate outcomes associated with TXA use in the setting of high- (HP) and low-profile (LP) introducer sheaths for resuscitative endovascular balloon occlusion of the aorta (REBOA). PARTICIPANTS: The Aortic Occlusion and Resuscitation for Trauma and Acute Care Surgery (AORTA) database was queried for patients who underwent REBOA using a low-profile 7 French (LP) or high-profile, 11-14 French (HP) introducer sheaths between 2013 and 2022. Demographics, physiology, and outcomes were examined for patients who survived beyond the index operation. RESULTS: 574 patients underwent REBOA (503 LP, 71 HP); 77% were male, mean age was 44 ± 19 and mean injury severity score (ISS) was 35 ± 16. 212 patients received TXA (181 [36%] LP, 31 [43.7%] HP). There were no significant differences in admission vital signs, GCS, age, ISS, SBP at AO, CPR at AO, and duration of AO among LP and HP patients. Overall, mortality was significantly higher in the HP (67.6%) vs the LP group (54.9%; P = .043). Distal embolism was significantly higher in the HP group (20.4%) vs the LP group (3.9%; P < .001). Logistic regression demonstrated that TXA use was associated with a higher rate of distal embolism in both groups (OR = 2.92; P = .021). 2 LP patients (one who received TXA) required an amputation. CONCLUSION: Patients who undergo REBOA are profoundly injured and physiologically devastated. Tranexamic acid was associated with a higher rate of distal embolism in those who received REBOA, regardless of access sheath size. For patients receiving TXA, REBOA placement should be accompanied by strict protocols for immediate diagnosis and treatment of thrombotic complications.

RESUMEN

BACKGROUND: Frequent neurological examinations in patients with traumatic brain injury (TBI) disrupt sleep-wake cycles and potentially contribute to the development of delirium. OBJECTIVE: To evaluate the risk of delirium among patients with TBI with respect to their neuro-check frequencies. METHODS: A retrospective study of patients presenting with TBI at a single level I trauma center between January 2018 and December 2019. The primary exposure was the frequency of neurological examinations (neuro-checks) assigned at the time of admission. Patients admitted with hourly (Q1) neuro-check frequencies were compared with those who received examinations every 2 (Q2) or 4 (Q4) hours. The primary outcomes were delirium and time-to-delirium. The onset of delirium was defined as the first documented positive Confusion Assessment Method for the Intensive Care Unit score. RESULTS: Of 1552 patients with TBI, 458 (29.5%) patients experienced delirium during their hospital stay. The median time-to-delirium was 1.8 days (IQR: 1.1, 2.9). Kaplan-Meier analysis demonstrated that patients assigned Q1 neuro-checks had the greatest rate of delirium compared with the patients with Q2 and Q4 neuro-checks ( P < .001). Multivariable Cox regression modeling demonstrated that Q2 neuro-checks (hazard ratio: 0.439, 95% CI: 0.33-0.58) and Q4 neuro-checks (hazard ratio: 0.48, 95% CI: 0.34-0.68) were protective against the development of delirium compared with Q1. Other risk factors for developing delirium included pre-existing dementia, tobacco use, lower Glasgow Coma Scale score, higher injury severity score, and certain hemorrhage patterns. CONCLUSION: Patients with more frequent neuro-checks had a higher risk of developing delirium compared with those with less frequent neuro-checks.

RESUMEN

BACKGROUND: Variations in admission patterns have been previously identified in non-elective surgical services, but minimal data on the subject exists with respect to burn admissions. Improved understanding of the temporal pattern of burn admissions could inform resource utilization and clinical staffing. We hypothesize that burn admissions have a predictable temporal distribution with regard to the time of day, day of week, and season of year in which they present. STUDY DESIGN: A retrospective, cohort observational study of a single burn center from 7/1/2016 to 3/31/2021 was performed on all admissions to the burn surgery service. Demographics, burn characteristics, and temporal data of burn admissions were collected. Bivariate absolute and relative frequency data was captured and plotted for all patients who met inclusion criteria. Heat-maps were created to visually represent the relative admission frequency by time of day and day of week. Frequency analysis grouped by total body surface area against time of day and relative encounters against day of year was performed. RESULTS: 2213 burn patient encounters were analyzed, averaging 1.28 burns per day. The nadir of burn admissions was from 07:00 and 08:00, with progressive increase in the rate of admissions over the day. Admissions peaked in the 15:00 hour and then plateaued until midnight (p<0.001). There was no association between day of week in the burn admission distribution (p>0.05), though weekend admissions skewed slightly later (p = 0.025). No annual, cyclical trend in burn admissions was identified, suggesting that there is no predictable seasonality to burn admissions, though individual holidays were not assessed. CONCLUSION: Temporal variations in burn admissions exist, including a peak admission window late in the day. Furthermore, we did not find a predictable annual pattern to use in guiding staffing and resource allocation. This differs from findings in trauma, which identified admission peaks on the weekends and an annual cycle that peaks in spring and summer.

RESUMEN

BACKGROUND: Extending the time to definitive hemorrhage control in noncompressible torso hemorrhage (NCTH) is of particular importance in the battlefield where transfer times are prolonged and NCTH remains the leading cause of death. While resuscitative endovascular balloon occlusion of the aorta is widely practiced as an initial adjunct for the management of NCTH, concerns for ischemic complications after 30 minutes of compete aortic occlusion deters many from zone 1 deployment. We hypothesize that extended zone 1 occlusion times will be enabled by novel purpose-built devices that allow for titratable partial aortic occlusion. METHODS: This is a cross-sectional analysis describing pREBOA-PRO zone 1 deployment characteristics at seven level 1 trauma centers in the United States and Canada (March 30, 2021, and June 30, 2022). To compare patterns of zone 1 aortic occlusion, the AORTA registry was used. Data were limited to adult patients who underwent successful occlusion in zone 1 (2013-2022). RESULTS: One hundred twenty-two patients pREBOA-PRO patients were included. Most catheters were deployed in zone 1 (n = 89 [73%]) with a median zone 1 total occlusion time of 40 minutes (interquartile range, 25-74). A sequence of complete followed by partial occlusion was used in 42% (n = 37) of zone 1 occlusion patients; a median of 76% (interquartile range, 60-87%) of total occlusion time was partial occlusion in this group. As was seen in the prospectively collected data, longer median total occlusion times were observed in the titratable occlusion group in AORTA compared with the complete occlusion group. CONCLUSION: Longer zone 1 aortic occlusion times seen with titratable aortic occlusion catheters appear to be driven by the feasibility of controlled partial occlusion. The ability to extend safe aortic occlusion times may have significant impact to combat casualty care where exsanguination from NCTH is the leading source of potentially preventable deaths.

RESUMEN

Despite the frequent hospitalizations and readmissions of persons living with dementia (PLWD), no telehealth transitional care interventions focus on PLWDs' unpaid caregivers. Tele-Savvy Caregiver Program is a 43-day evidence-based online psychoeducational intervention for PLWDs' caregivers. The aim of this formative evaluation was to explore caregivers' acceptability of and experience with their participation in Tele-Savvy after their PLWDs' hospital discharge. Additionally, we gathered caregivers' feedback on the recommended features of a transitional care intervention, suitable for caregivers' schedule and needs post-discharge. Fifteen caregivers completed the interviews. Data were analyzed via conventional content analysis. Four categories were identified: (1) Tele-Savvy improved participants' understanding of dementia and caregiving; (2) hospitalization started a "new level of normal"; (3) PLWDs' health concerns; and (4) transitional care intervention development. Participation in Tele-Savvy was acceptable for most caregivers. Participants' feedback provides content and structural guidance for the development of a new transitional care intervention for PLWDs' caregivers.

RESUMEN

INTRODUCTION: Antibiotics are time-critical in the management of sepsis. When infectious organisms are unknown, patients are treated with empiric antibiotics to include coverage for gram-negative organisms, such as antipseudomonal cephalosporins and penicillins. However, in observational studies, some antipseudomonal cephalosporins (eg, cefepime) are associated with neurologic dysfunction while the most common antipseudomonal penicillin (piperacillin-tazobactam) is associated with acute kidney injury (AKI). No randomised control trials have compared these regimens. This manuscript describes the protocol and analysis plan for a trial designed to compare the effects of antipseudomonal cephalosporins and antipseudomonal penicillins among acutely ill patients receiving empiric antibiotics. METHODS AND ANALYSIS: The Antibiotic Choice On ReNal outcomes trial is a prospective, single-centre, non-blinded randomised trial being conducted at Vanderbilt University Medical Center. The trial will enrol 2500 acutely ill adults receiving gram-negative coverage for treatment of infection. Eligible patients are randomised 1:1 to receive cefepime or piperacillin-tazobactam on first order entry of a broad-spectrum antibiotic covering gram-negative organisms. The primary outcome is the highest stage of AKI and death occurring between enrolment and 14 days after enrolment. This will be compared between patients randomised to cefepime and randomised to piperacillin-tazobactam using an unadjusted proportional odds regression model. The secondary outcomes are major adverse kidney events through day 14 and number of days alive and free of delirium and coma in 14 days after enrolment. Enrolment began on 10 November 2021 and is expected to be completed in December 2022. ETHICS AND DISSEMINATION: The trial was approved by the Vanderbilt University Medical Center institutional review board (IRB#210591) with a waiver of informed consent. Results will be submitted to a peer-reviewed journal and presented at scientific conferences. TRIAL REGISTRATION NUMBER: NCT05094154.

RESUMEN

BACKGROUND: There is currently no standard for documenting supervision of acute care surgery (ACS) fellows. To accomplish this goal, we developed a web-based survey that is accessible via mobile platform. We hypothesize that our mobile access survey is an effective, reproducible tool for assessing fellow clinical performance. METHODS: A retrospective review from 2016 to 2022 of all data captured in an encrypted database on all ACS fellows at our institution was performed. Supervision was defined as: Type 1 direct face-to-face, Type 2a immediately available in-house, Type 2b available after notification via phone with remote electronic medical record access, and Type 3 retrospective review. Data were collected by supervising faculty using a web-based clinical performance survey created by fellowship program leadership. Survey data collected included clinical summary, trainee, proctoring faculty, clinical service, operative/nonoperative, supervision type, Zwisch autonomy scale, time to input data, and graduate medical education milestone performance. Data were analyzed using descriptive statistics. RESULTS: A total of 883 proctoring events were identified, including the majority as Type 1 (97.4%). Trauma comprised 64% of evaluations. Fifty-two percent of the proctoring events were surgical cases. Complexity was graded as average (77%), hardest (16%), basic (7%). Guidance included supervision only, 491 of 666 (74%), with 26% requiring faculty intervention. Fellow performance was graded as average (66%), above average (31%), and below average/critical deficiency (3%). Graduate medical education performance was available for 247 of 883 interactions identifying 31 events with potential for improvement. Average evaluation completion time: 2 minutes (n = 134). CONCLUSION: A mobile web-based survey is a convenient and reliable tool for documenting ACS fellow clinical activity and was effectively used by all ACS faculty to record supervision.

RESUMEN

Tracheostomy for prolonged ventilation of patients with COVID-19 was often delayed due to high viral loads and persistent high ventilatory requirements. With prolonged intubation and significant dose corticosteroid use, patients with COVID-19 are at risk for tracheomalacia, and urgent tube exchange may be required to address persistent cuff leak and to maintain adequate mechanical ventilation. We sought to describe our single center experience with COVID-19 patients requiring tracheostomy and the tracheal complications that followed. We performed a review of patients with COVID-19 who underwent tracheostomy from June 2020 to October 2021. 45 patients were identified; 82.2% survived their index hospitalization. Tracheostomy was performed after 16.4 days of mechanical ventilation. 22.2% required urgent exchange to an extended length tracheostomy tube after 7.2 days from initial tracheostomy. Placement of an extended length tracheostomy tube can reduce cuff leak in ventilated COVID-19 patients and may be considered during initial tracheostomy placement.
