Interfacility Transfer for Nonelective Cholecystectomy in High MELD Patients: An ACS-NSQIP Analysis.

INTRODUCTION: Interfacility transfer to a referral center is often considered for patients with liver disease undergoing nonelective cholecystectomy given management complexities and perioperative risk. We sought to determine the association between the Model for End Stage Liver Disease (MELD) score, transfer frequency, and outcomes in those patients using a national database. MATERIALS AND METHODS: The ACS-NSQIP participant use files were queried for nonelective open or laparoscopic cholecystectomy from 2016 to 2018. Patients were grouped according to low (6-11), intermediate (12-18), or high (>18) MELD. In the high MELD group, patient characteristics and outcomes were compared between transferred and nontransferred patients and multivariate regression was performed to evaluate independent predictors of outcomes. Outcomes included in-hospital mortality, complications, length-of-stay (LOS), and 30-d reoperation and readmission. RESULTS: 30,171 subjects were included. Transfer was more likely as MELD increased (19.5% high versus 12.1% low, P < 0.001). High MELD patients had increased LOS, reoperation, readmission, and mortality rates compared to low MELD. In high MELD patients (n = 1016), those transferred were more likely older, white, obese, and septic. Transferred patients had increased mortality (7.6% versus 4.2%, P = 0.044), LOS, reoperation, and complications. After controlling for differences between transferred and nontransferred patients, transfer status was not independently associated with mortality (OR = 1.593, P = 0.177), postoperative complications or LOS, but was associated with increased risk for reoperation. Sepsis and laparoscopic surgery were independently associated with higher and lower mortality, respectively. CONCLUSIONS: Transfer status is not independently associated with mortality, postoperative complications, or prolonged LOS, suggesting patients with advanced liver disease undergoing acute cholecystectomy may not benefit from interfacility transfer.

Delayed Diagnosis of Tandem Spinal Stenosis: A Retrospective Institutional Review.

BACKGROUND: Tandem spinal stenosis (TSS) is defined as simultaneous spinal stenosis in the cervical, thoracic, and/or lumbar regions and may present with both upper and lower motor neuron symptoms, neurogenic claudication, and gait disturbance. Current literature has focused mainly on the prevalence of TSS and treatment methods, while the incidence of delayed TSS diagnosis is not well defined. The purpose of this study was to determine the incidence of delayed TSS diagnosis at our institution and describe the clinical characteristics commonly observed in their particular presentation. METHODS: Following institutional review board approval, an institutional billing database review was performed for patients who underwent a spinal decompression procedure between 2006 and 2016. Thirty-three patients who underwent decompression on 2 separate spinal regions within 1 year were included for review. Patients with delayed diagnosis of TSS following the first surgery were differentiated from those with preoperative diagnosis of TSS. RESULTS: TSS requiring surgical decompression occurred in 33 patients, with the incidence being 2.06% in this cohort. Fifteen patients received a delayed diagnosis after the first surgical decompression (45%) and were found to have a longer interval between decompressions (7.6 ± 2.1 months versus 4.01 ± 3 months, P = .0004). Patients undergoing lumbar decompression as the initial procedure were more likely to have a delayed diagnosis of TSS (8 versus 2 patients, P = .0200). The most common presentation of delayed TSS was pain and myelopathic symptoms that persisted after decompressive surgery. CONCLUSION: TSS should remain within the differential diagnosis for patients at initial presentation of spinal stenosis. In addition, suspicion of TSS should be heightened if preoperative symptoms fail to expectedly improve following decompression even if overt myelopathic signs are not present. LEVEL OF EVIDENCE: 4.

Outcomes of multilevel vertebrectomy for spondylodiscitis.

BACKGROUND CONTEXT: The incidence of pyogenic vertebral osteomyelitis (PVO) continues to increase in the United States, highlighting the need to recognize unique challenges presented by these cases and develop effective methods of surgical management. To date, no prior research has focused on the outcomes of PVO requiring two or more contiguous corpectomies. PURPOSE: To describe our experience in the operative management of PVO in 56 consecutive patients who underwent multilevel corpectomies (≥2 vertebral bodies) via a combined approach. STUDY DESIGN/SETTING: Single institution retrospective cohort review between January 2002 and December 2015. All patients had been treated at an academic tertiary referral center by one of two fellowship-trained orthopedic spine surgeons. PATIENT SAMPLE: Patient records were cross-referenced with International Classification of Diseases osteomyelitis codes and paravertebral abscess code. Inclusion criteria for the study were patients within the cohort who had adequate medical records for review, a minimum patient age of 18 years, active vertebral osteomyelitis as an indication for surgical intervention, a minimum of 1-year radiographic follow-up, and surgical intervention that included at least two complete vertebral corpectomies. Subsequently, 56 patients met the inclusion criteria and were reviewed for this retrospective analysis. OUTCOME MEASURES: Outcomes of interest were readmission and reoperation rates related to treatment of PVO, 30-day and 1-year mortality rates, radiographic outcomes, perioperative complications, infection control, and length of stay. METHODS: After obtaining approval from the Institutional Review Board, retrospective review was performed on records of all adults with PVO refractory to standard nonoperative treatment who underwent complete corpectomy of two or more contiguous vertebrae at a single institution between January 2002 and December 2015. This study was not funded, and no potential conflict of interest-associated biases were present. RESULTS: Fifty-six patients were identified (63% men; mean age 56.8 years; mean radiographic follow-up 2.8 years). Median length of stay was 13 days with nearly half readmitted (47%) after a median of 222.5 days after surgery. Twelve (22%) posterior revisions were required after a median 54 days for infection, painful or failed hardware, proximal junction kyphosis, adjacent level disease, or extension of the fusion. Thirty-day and 1-year mortality rates were 7.14% and 19.6%, respectively, with an infectious etiology as the most common cause of death. CONCLUSIONS: Multilevel vertebral corpectomy for treatment of refractory vertebral osteomyelitis is associated with relatively high rates of complications and mortality compared with historical controls for 1 or 2 level procedures. We found clinical resolution and absence of complications requiring return to the operating room in 75% of patients when complete extirpation of the involved vertebrae is achieved. Our findings suggest multilevel anterior corpectomies with posterior stabilization may be a reasonable surgical option when approaching patients with complicated spondylodiscitis.

Mass-Gathering Medical Care in Electronic Dance Music Festivals.

Introduction Electronic dance music (EDM) festivals represent a unique subset of mass-gathering events with limited guidance through literature or legislation to guide mass-gathering medical care at these events. Hypothesis/Problem Electronic dance music festivals pose unique challenges with increased patient encounters and heightened patient acuity under-estimated by current validated casualty predication models. METHODS: This was a retrospective review of three separate EDM festivals with analysis of patient encounters and patient transport rates. Data obtained were inserted into the predictive Arbon and Hartman models to determine estimated patient presentation rate and patient transport rates. RESULTS: The Arbon model under-predicted the number of patient encounters and the number of patient transports for all three festivals, while the Hartman model under-predicted the number of patient encounters at one festival and over-predicted the number of encounters at the other two festivals. The Hartman model over-predicted patient transport rates for two of the three festivals. CONCLUSION: Electronic dance music festivals often involve distinct challenges and current predictive models are inaccurate for planning these events. The formation of a cohesive incident action plan will assist in addressing these challenges and lead to the collection of more uniform data metrics.
