Challenges in Predicting Discharge Disposition for Trauma and Emergency General Surgery Patients.

BACKGROUND: Changes in discharge disposition and delays in discharge negatively impact the patient and hospital system. Our objectives were1 to determine the accuracy with which trauma and emergency general surgery (TEGS) providers could predict the discharge disposition for patients and2 determine the factors associated with incorrect predictions. METHODS: Discharge dispositions and barriers to discharge for 200 TEGS patients were predicted individually by members of the multidisciplinary TEGS team within 24 h of patient admission. Univariate analyses and multivariable logistic least absolute shrinkage and selection operator regressions determined the associations between patient characteristics and correct predictions. RESULTS: A total of 1,498 predictions of discharge disposition were made by the multidisciplinary TEGS team for 200 TEGS patients. Providers correctly predicted 74% of discharge dispositions. Prediction accuracy was not associated with clinical experience or job title. Incorrect predictions were independently associated with older age (OR 0.98; P < 0.001), trauma admission as compared to emergency general surgery (OR 0.33; P < 0.001), higher Injury Severity Scores (OR 0.96; P < 0.001), longer lengths of stay (OR 0.90; P < 0.001), frailty (OR 0.43; P = 0.001), ICU admission (OR 0.54; P < 0.001), and higher Acute Physiology and Chronic Health Evaluation II scores (OR 0.94; P = 0.006). CONCLUSION: The TEGS team can accurately predict the majority of discharge dispositions. Patients with risk factors for unpredictable dispositions should be flagged to better allocate appropriate resources and more intensively plan their discharges.

Improving trauma tertiary survey performance and missed injury identification using an education-based quality improvement initiative.

BACKGROUND: Performance of a trauma tertiary survey (TTS) reduces rates of missed injuries, but performance has been inconsistent at trauma centers. The objectives of this study were to assess whether quality improvement (QI) efforts would increase the frequency of TTS documentation and determine if TTS documentation would increase identification of traumatic injuries. Our hypothesis was that QI efforts would improve documentation of the TTS. METHODS: Before-and-after analysis of QI interventions at a level 1 trauma center was performed. The interventions included an electronic template for TTS documentation, customized educational sessions, and emphasis from trauma leadership on TTS performance. The primary outcome was documentation of the TTS. Detection of additional injuries based on tertiary evaluation was a secondary outcome. Associations between outcomes and categorical patient and encounter characteristics were assessed using χ2 tests. RESULTS: Overall, 592 trauma encounters were reviewed (296 preimplementation and 296 postimplementation). Trauma tertiary survey documentation was significantly higher after implementation of the interventions (30.1% preimplementation vs. 85.1% postimplementation, p < 0.001). Preimplementation documentation of the TTS was less likely earlier in the academic year (14.3% first academic quarter vs. 46.5% last academic quarter, p < 0.001), but this temporal pattern was no longer evident postimplementation (88.5% first academic quarter vs. 77.9% last academic quarter, p = 0.126). Patients were more likely to have a missed traumatic injury diagnosed on TTS postimplementation (1.7% in preimplementation vs. 5.7% postimplementation, p = 0.009). CONCLUSION: Documentation of the TTS and missed injury detection rates were significantly increased following implementation of a bundle of QI interventions. The association between time of year and documentation of the TTS was also attenuated, likely through reduction of the resident learning curve. Targeted efforts to improve TTS performance may improve outcomes for trauma patients at teaching hospitals. LEVEL OF EVIDENCE: Care management, Level IV.

Prosopagnosia associated with brain metastasis near the inferior longitudinal fasciculus in the nondominant temporal lobe: illustrative case.

BACKGROUND: Disruptions of the inferior longitudinal fasciculus (ILF) in the nondominant temporal lobe can lead to the rare but significant higher visual-processing disturbance of prosopagnosia. Here, the authors describe a 57-year-old right hand-dominant female with a large breast cancer brain metastasis in the right temporal lobe who underwent resection and subsequent Gamma Knife radiosurgery. She presented with difficulty with facial recognition, but following surgical intervention, the prosopagnosia became more profound. OBSERVATIONS: Even in nondominant cortex, significant deficits can arise when operating near higher visual-processing centers, including the ILF. LESSONS: This case highlights the utility of imaging-based tractography obtained from preoperative imaging for resective surgical planning even when operating in areas that do not involve what is traditionally considered elegant areas of the brain. To optimize neurological outcomes in metastatic tumor resection, awareness and diffusion tensor imaging of neighboring, displaced white matter tracts may prevent permanent deficits in higher visual processing.

A National Survey Evaluating the Impact of the COVID-19 Pandemic on Students Pursuing Careers in Neurosurgery.

Background: The COVID-19 pandemic has profoundly disrupted medical education and the residency application process. Methods: We conducted a descriptive observational study in April 2020 of medical students and foreign medical graduates considering or pursuing careers in neurosurgery in the United States to examine the impact of the pandemic. Results: A total of 379 respondents from 67 medical schools completed the survey. Across all participants, 92% (n = 347) stopped in-person didactic education, and 43% (n = 161) experienced basic science and 44% (n = 167) clinical research delays. Sixty percent (n = 227) cited a negative impact on academic productivity. Among first year students, 18% (n = 17) were less likely to pursue a career in neurosurgery. Over half of second year and third year students were likely to delay taking the United States Medical Licensing Examination Steps I and II. Among third year students, 77% (n = 91) reported indefinite postponement of sub-internships, and 43% (n = 53) were unsatisfied with communication from external programs. Many fourth-year students (50%, n = 17) were graduating early to participate in COVID-19-related patient care. Top student-requested support activities included access to student-focused educational webinars and sessions at upcoming conferences. Conclusions: Medical students pursuing careers in neurosurgery faced unique academic, career, and personal challenges secondary to the pandemic. These challenges may become opportunities for new initiatives guided by professional organizations and residency programs.

Trends in national utilization of posterior lumbar fusion and 30-day reoperation and readmission rates from 2006-2016.

OBJECTIVE: The primary goal of this study is to determine trends in patient 30-day postoperative readmission and reoperation following elective posterior lumbar fusion (PLF) between 2006-2016. METHODS: We retrospectively identified patients in the ACS-NSQIP database who underwent elective, non-emergent PLF from 2006 to 2016. Descriptive statistical and time trend analyses were performed on demographic, comorbidities, perioperative, and outcome variables. Primary outcomes were reoperation and readmission within 30 days and secondary outcomes were medical and surgical complications reported within 30 days of the operation. Linear and binary logistic regression were performed to adjust for patient specific confounders. RESULTS: A total of 26,265 patients underwent elective PLF over the study period. Overall case volume increased from 0.02 % (n = 27) of all total cases in ACS-NSQIP in 2006 to 0.82 % (n = 8228) in 2016. Mean age increased from 51.22 [SE: 2.77] in 2006 to 60.57 [SE: 0.14] in 2016 (p < 0.001). For comorbidities, there was a decrease in smokers and increase in hypertension requiring medication and ASA Class 3. A readmission rate of around 5% per year did not vary significantly over the study period (p = 0.531). Unplanned reoperations declined from 7.4 % in 2006 to 3.1 % in 2016, but the overall trend from 2006 to 2016 was not statistically significant (p = 0.139). Reoperation demonstrated a significant association between age and BMI, but did not vary with admission year. Surgical site infections followed by hematomas and seromas were listed as the most common cause of both readmission and reoperation in PLF patients. CONCLUSION: Since the establishment of the ACS-NSQIP database, reoperation rates due to complications declined after 2006 and remained relatively stable. Readmissions were added as a variable in 2011 and had no significant changes over time.

Intraventricular adult Taenia solium causing hydrocephalus: A case report.

BACKGROUND: Neurocysticercosis (NCC) is the most common parasitic infection of the central nervous system worldwide and is caused by the larval form of the tapeworm Taenia solium. In general, T. solium larval form may be located in the neuraxis, resulting in pathology. Here, we report a rare case of female with a history of adult onset seizures presenting with adult form T. solium in the fourth ventricle, causing hydrocephalus. CASE DESCRIPTION: A 36-year-old female patient with a known history of adult onset seizures presented with a 1-year history of progressively worsening bilateral headaches with vertigo and intermittent nausea. A computerized tomography scan revealed ventriculomegaly and transependymal flow, with an obstruction at the level of the fourth ventricle. Outpatient magnetic resonance imaging demonstrated obstructive hydrocephalus secondary to a lobulated cystic mass within the fourth ventricle, demonstrating a gross appearance consistent with racemose NCC. The patient underwent endoscopic third ventriculostomy, and gross examination of the resected cyst revealed a mature T. solium larvae encased in a cystic membrane. Given that our patient was born and raised in Mexico but had not returned since the age of 8, NCC was an unexpected finding. CONCLUSION: The present case highlights the importance of maintaining high suspicion for NCC in all patients presenting with seizures or hydrocephalus of unknown cause. Even in patients with a very remote history of residence in an endemic country, NCC can be an overlooked, underlying cause of both chronic neurologic symptoms, as well as acute, life-threatening neurologic emergencies.

Predicting length of stay for trauma and emergency general surgery patients.

BACKGROUND: Predicting length of stay (LOS) is difficult for trauma and emergency general surgery (TEGS) patients. Our aim was to determine the accuracy of LOS predictions by TEGS team members and the NSQIP Risk Calculator and the patient factors associated with inaccurate predictions. METHODS: LOS for 200 TEGS patients were predicted. Full-model univariate and multivariable linear regressions were used to determine associations between patient characteristics and inaccurate predictions. RESULTS: There were 1,518 predictions of LOS. LOS predictions were rarely correct (TEGS team: 30.7% all patients, 35.6% surgical; NSQIP: 33.0% surgical). No individual group nor NSQIP was significantly better at predicting LOS. Inaccurate predictions were associated with female patients, longer LOS, trauma, frailty, higher comorbidity and injury severity scores, and lesser disposition. CONCLUSION: Both the TEGS team and NSQIP are poor at predicting LOS for TEGS patients. Further work helping to guide LOS predictions for TEGS patients is warranted.

Trends in National Use of Anterior Cervical Discectomy and Fusion from 2006 to 2016.

OBJECTIVE: Anterior cervical discectomy and fusion (ACDF) is the most common procedure for the treatment of degenerative cervical conditions. The objective of this study is to determine time-dependent trends in patient outcomes following ACDF for degenerative disease from 2006 to 2016. METHODS: We used the National Surgical Quality Improvement Program (NSQIP) database to retrospectively review all patients who underwent elective ACDF between 2006 and 2016. A descriptive statistical analysis followed by time trend analysis was performed on demographics, comorbidities, perioperative, and outcome variables. Primary outcomes were reoperation and readmission rates. Secondary outcomes were medical and surgical complications reported within 30 days of operation. RESULTS: A total of 36,854 patients underwent elective ACDF from the 2006 to 2016 NSQIP database. Mean age increased from 48.19 years [standard error: 1.49] in 2006 to 54.08 years [standard error: 0.12] in 2016 (P < 0.001). There was a significantly greater number of outpatient procedures from 2012 to 2016 (P < 0.001). The proportion of patients with American Society of Anesthesiologists classes 3/4 significantly increased over time (P < 0.001, P < 0.001, P = 0.005, respectively). Readmission risk, first documented in NSQIP in 2011, increased over time from 2011 to 2016 (P < 0.001). Unplanned reoperations have remained consistent at about 1.4%. Postoperative complications varied over time with no discernable patterns or trends. CONCLUSIONS: Since the establishment of the NSQIP database, there have been no considerable improvements in reoperation or postoperative complication rates based on available data, however, there have been increased rates of readmission. Changes in data collection and an aging patient population with greater burden of comorbidities could confound these trends.

A Systematic Review of Neurosurgical Care in Low-Income Countries.

OBJECTIVE: More than 5 billion individuals lack access to essential surgical care. Neurosurgical care is especially limited in low-income countries (LICs). Studies describing neurosurgical care in LICs are critical for understanding global disparities in access to neurosurgical procedures. To better understand these disparities, we conducted a systematic review of the literature identifying neurosurgical patients in LICs. METHODS: MEDLINE (PubMed), Embase (embase.com), and Cochrane Library (Wiley) databases were systematically searched to retrieve studies describing neurosurgical care in LICs as defined by the World Bank Country and Lending Groups income classification. All databases were searched from their inception; no date or language limits were applied. All the articles were blindly reviewed by 2 individuals. Data from eligible studies were extracted and summarized. RESULTS: Of the 4377 citations screened, 154 studies met inclusion criteria. The number of publications substantially increased over the study period, with 49% (n = 76) of studies published in the last 5 years. Twenty-six percent (n = 40) of studies had a first author, and 30% (n = 46) had a senior author, affiliated with a country different from the LIC of study. The most common neurosurgical diagnosis was traumatic brain injury (24%, n = 37), followed by hydrocephalus (26%, n = 40), and neoplastic intracranial mass (10%, n = 16). Of LICs, 43% (n = 15/35) had no published neurosurgical literature. CONCLUSIONS: There is a significant deficit in the literature on neurosurgical care in LICs. Efforts must focus on supporting research initiatives in LICs to improve publication bias and understand disparities in access to neurosurgical care in the lowest-resource countries.

Electronic Medical Record Versus Bedside Assessment: How to Evaluate Frailty in Trauma and Emergency General Surgery Patients?

BACKGROUND: Screening patients for frailty is traditionally done at the bedside. However, recent electronic medical record (EMR)-based, comorbidity-focused frailty assessments have been developed. Our objective was to determine how a common bedside frailty assessment, the trauma and emergency surgery (TEGS) frailty index (FI), compares to an EMR-based frailty assessment in predicting geriatric TEGS outcomes. MATERIALS AND METHODS: We retrospectively reviewed our quality improvement project database consisting of TEGS patients ≥ 65 y old. Patients were screened with the TEGS FI, a 15-question bedside assessment, including comorbidities, physical activity, emotional health, and nutrition. Six of 15 items were retrievable from the enterprise data warehouse (EDW), storing all EMR data from Northwestern Memorial Hospital, and use to calculate the EDW frailty score. Patient characteristics and outcomes were compared between different groups. RESULTS: Two hundred thirty-six geriatric TEGS patients were included, of which 75 (31.8%) were TEGS FI frail and 60 (25.4%) were EDW frail. TEGS FI frail patients had increased length of stay (LOS), loss of independence (LOI), and complications compared to TEGS FI nonfrail patients. EDW frail patients had higher LOS and complications than EDW nonfrail patients but similar LOI. TEGS FI and EDW frail patients had similar outcomes except TEGS FI-only patients more often have LOI. CONCLUSIONS: Bedside frailty assessments and EMR-based assessments are both effective in identifying geriatric TEGS patients at risk for increased LOS and complications. However, bedside frailty screening was better at identifying patients who have LOI and may be a more appropriate choice when screening for frailty.
