The Impact of Palliative Medicine Consultation on Readmission Rates and Hospital Costs in Surgical Patients Requiring Prolonged Mechanical Ventilation.

BACKGROUND: The use of palliative care for critically ill hospitalized patients has expanded. However, it is still underutilized in surgical specialties. Postsurgical patients requiring prolonged mechanical ventilation have increased mortality and costs of care; outcomes from adding palliative care services to this population have been poorly investigated. The objective of this study was to determine the impact of palliative medicine consultation on readmission rates and hospitalization costs in postsurgical patients requiring prolonged mechanical ventilation. METHODS: The Nationwide Readmissions Database was queried for adults (> 18 years) between the years 2010 and 2014 who underwent a major operation (Healthcare Cost and Utilization Project [HCUP] data element ORPROC = 1), required mechanical ventilation for ≥ 96 consecutive hours (ICD-9-CM V46.1), and survived until discharge. Among these, patients who received a palliative medicine consultation during hospitalization were identified using the ICD-9-CM diagnosis code V66.7. RESULTS: Of 53,450 included patients, 3.4% received a palliative care consultation. Compared to patients who did not receive a palliative care consultation, patients who did receive a consultation had a lower readmission rate (14.8% vs. 24.8%, p < 0.001) and lower average cost of hospitalization during the initial admission ($109,007 vs. $124,218, p < 0.001), findings that persisted after multivariable logistic regression. CONCLUSION: Utilization of palliative care in surgical patients remains low. Palliative care consultation in postsurgical patients requiring prolonged mechanical ventilation was associated with lower cost and rate of readmission. Further work is needed to integrate palliative care services with surgical care.

The Power Law in Operating Room Management.

The Acute Care Surgery model has been implemented by many hospitals in the United States. As complex adaptive systems, healthcare systems are composed of many interacting elements that respond to intrinsic and extrinsic inputs. Systems level analysis may reveal the underlying organizational structure of tactical block allocations like the Acute Care Surgery model. The purpose of this study is to demonstrate one method to identify a key characteristic of complex adaptive systems in the perioperative services. Start and end times for all surgeries performed at the University of Vermont Medical Center OR1 were extracted for two years prior to the transition to an Acute Care Surgery service and two years following the transition. Histograms were plotted for the inter-event times calculated from the difference between surgical cases. A power law distribution was fit to the post-transition histogram. The Kolmogorov-Smirnov test for goodness-of-fit at 95% level of significance shows the histogram plotted from post-transition inter-event times follows a power law distribution (K-S = 0.088, p = 0.068), indicating a Complex Adaptive System. Our analysis demonstrates that the strategic decision to create an Acute Care Surgery service has direct implications on tactical and operational processes in the perioperative services. Elements of complex adaptive systems can be represented by a power law distributions and similar methods may be applied to identify other processes that operate as complex adaptive systems in perioperative care. To make sustained improvements in the perioperative services, focus on manufacturing-based interventions such as Lean Six Sigma should instead be shifted towards the complex interventions that modify system-specific behaviors described by complex adaptive system principles when power law relationships are present.

Avoiding Cribari gridlock 2: The standardized triage assessment tool outperforms the Cribari matrix method in 38 adult and pediatric trauma centers.

OBJECTIVES: The Cribari Matrix Method (CMM) is the current standard to identify over/undertriage but requires manual trauma triage reviews to address its inadequacies. The Standardized Triage Assessment Tool (STAT) partially emulates triage review by combining CMM with the Need For Trauma Intervention, an indicator of major trauma. This study aimed to validate STAT in a multicenter sample. METHODS: Thirty-eight adult and pediatric US trauma centers submitted data for 97,282 encounters. Mixed models estimated the effects of overtriage and undertriage versus appropriate triage on the odds of complication, odds of discharge to a continuing care facility, and differences in length of stay for both CMM and STAT. Significance was assessed at p <0.005. RESULTS: Overtriage (53.49% vs. 30.79%) and undertriage (17.19% vs. 3.55%) rates were notably lower with STAT than with CMM. CMM and STAT had significant associations with all outcomes, with overtriages demonstrating lower injury burdens and undertriages showing higher injury burdens than appropriately triaged patients. STAT indicated significantly stronger associations with outcomes than CMM, except in odds of discharge to continuing care facility among patients who received a full trauma team activation where STAT and CMM were similar. CONCLUSIONS: This multicenter study strongly indicates STAT safely and accurately flags fewer cases for triage reviews, thereby reducing the subjectivity introduced by manual triage determinations. This may enable better refinement of activation criteria and reduced workload.

Demographics, Treatment, and Cost of Periprosthetic Femur Fractures: Fixation Versus Revision.

INTRODUCTION: Periprosthetic femur fractures (PPFX) are complications of both total hip and knee arthroplasty and may be treated with open reduction and internal fixation (ORIF) or revision arthroplasty. Differences in treatment and fracture location may be related to patient demographics and lead to differences in cost. Our study examined the effects of demographics and treatment of knee and hip PPFXs on length of stay (LOS) and cost. METHODS: Of all, 932 patients were identified with hip or knee PPFXs in the National Inpatient Sample from January 2013 to September 2015. Age, gender, race, mortality, comorbidity level, LOS, total cost, procedure type, geographic region, and hospital type were recorded. A generalized linear regression model was conducted to analyze the effect of fracture type on LOS and cost. RESULTS: Differences in gender (66% vs 83.7% female, P < .01), comorbidities (fewer in hips, P < .01), and costs (US$30 979 vs US$27 944, P < .01) were found between the hip and knee groups. Knees had significantly higher rates of ORIF treatment (80.7% vs 39.1%) and lower rates of revision arthroplasties (19.3% vs 60.9%) than hip PPFXs (P < .01). Within both groups, patients with more comorbidities, revision surgery, and blood transfusions were more likely to have a longer LOS and higher cost. CONCLUSION: Periprosthetic femur fractures patients are not homogenous and treatment varies between hip and knee locations. For knee patients, those treated with ORIF were younger, with fewer comorbidities than those treated with revision. Conversely, hip patients treated with ORIF were older, with more comorbidities than those treated with revision. Hips had higher costs than knees, and cost correlated with revision arthroplasty and more comorbidities. In both hip and knee groups, longer LOS was associated with more comorbidities and being treated in urban teaching hospitals. Total cost had the strongest associations with revision procedures as well as number of comorbidities and blood product use.

Association of Insurance Status With Treatment and Outcomes in Pediatric Patients With Severe Traumatic Brain Injury.

OBJECTIVE: To determine whether a health insurance disparity exists among pediatric patients with severe traumatic brain injury using the National Trauma Data Bank. DESIGN: Retrospective cohort study. SETTING: National Trauma Data Bank, a dataset containing more than 800 trauma centers in the United States. PATIENTS: Pediatric patients (< 18 yr old) with a severe isolated traumatic brain injury were identified in the National Trauma Database (years 2007-2016). Isolated traumatic brain injury was defined as patients with a head Abbreviated Injury Scale score of 3+ and excluded those with another regional Abbreviated Injury Scale of 3+. INTERVENTIONS: None. MEASUREMENT AND MAIN RESULTS: Procedure codes were used to identify four primary treatment approaches combined into two classifications: craniotomy/craniectomy and external ventricular draining/intracranial pressure monitoring. Diagnostic criteria and procedure codes were used to identify condition at admission, including hypotension, Glasgow Coma Scale, mechanism and intent of injury, and Injury Severity Score. Children were propensity score matched using condition at admission and other characteristics to estimate multivariable logistic regression models to assess the associations among insurance status, treatment, and outcomes. Among the 12,449 identified patients, 91.0% (n = 11,326) had insurance and 9.0% (n = 1,123) were uninsured. Uninsured patients had worse condition at admission with higher rates of hypotension and higher Injury Severity Score, when compared with publicly and privately insured patients. After propensity score matching, having insurance was associated with a 32% (p = 0.001) and 54% (p < 0.001) increase in the odds of cranial procedures and monitor placement, respectively. Insurance coverage was associated with 25% lower odds of inpatient mortality (p < 0.001). CONCLUSIONS: Compared with insured pediatric patients with a traumatic brain injury, uninsured patients were in worse condition at admission and received fewer interventional procedures with a greater odds of inpatient mortality. Equalizing outcomes for uninsured children following traumatic brain injury requires a greater understanding of the factors that lead to worse condition at admission and policies to address treatment disparities if causality can be identified.

Effects of the Affordable Care Act on Vascular Patient Amputation Rates in Arkansas.

BACKGROUND: The Patient Protection and Affordable Care Act was signed into law in 2010 and enacted in 2013 which improved insurance coverage across America due to increasing Medicaid eligibility as well as changes to individual insurance markets. In Arkansas, this was implemented by a Medicaid expansion waiver which allowed patients to purchase insurance with funds provided by the government to subsidize premiums through the marketplace. The goal of this study was to determine the effects of the Affordable Care Act (ACA) on Arkansas patients with peripheral arterial disease. METHODS: A pre-post research design using the Arkansas Hospital Discharge Dataset was used to study the impact of the ACA on limb amputation, distal bypass, discharge disposition, and total costs for patients diagnosed with peripheral arterial disease/atherosclerosis. The data were obtained for the years 2007 through 2009 (pre-ACA), 2011 through 2013 (post-ACA), and 2014 through 2015 (post-Arkansas expansion). Bivariate analysis, analysis of variance, and regression analyses were performed to analyze the data. RESULTS: A total of 10,923 patients were identified. Uninsured patients ("self-pay") decreased from 7% pre-ACA to 3.4% post-Arkansas expansion (P < 0.0001). There was a decrease in adjusted health-care costs after the Arkansas expansion (P < 0.0001). There was no change in mortality or transfer to rehabilitation facilities, but there was an increase in discharge to skilled nursing facilities along with a decrease in patients being discharged home (P < 0.0001). Regression analysis showed private insurance to be associated with a 49% reduction in the odds of an amputation (P < 0.0001). The Arkansas expansion was associated with a 26% reduction in the odds of an amputation when compared with that before the ACA implementation (P < 0.005). Having private insurance was associated with a 26% increase in the odds of having a bypass when compared with uninsured patients (P < 0.05). CONCLUSIONS: Patients with private insurance have a decreased chance of amputation and increased odds of having a bypass when compared with patients who were of the self-pay category. The increase in private insurance coverage in our patient population could improve the rate of amputation in the vascular population in Arkansas by increasing early interventions for peripheral vascular disease.

Development and validation of surgical training tool: cystectomy assessment and surgical evaluation (CASE) for robot-assisted radical cystectomy for men.

BACKGROUND: We aimed to develop a structured scoring tool: cystectomy assessment and surgical evaluation (CASE) that objectively measures and quantifies performance during robot-assisted radical cystectomy (RARC) for men. METHODS: A multinational 10-surgeon expert panel collaborated towards development and validation of CASE. The critical steps of RARC in men were deconstructed into nine key domains, each assessed by five anchors. Content validation was done utilizing the Delphi methodology. Each anchor was assessed in terms of context, score concordance, and clarity. The content validity index (CVI) was calculated for each aspect. A CVI ≥ 0.75 represented consensus, and this statement was removed from the next round. This process was repeated until consensus was achieved for all statements. CASE was used to assess de-identified videos of RARC to determine reliability and construct validity. Linearly weighted percent agreement was used to assess inter-rater reliability (IRR). A logit model for odds ratio (OR) was used to assess construct validation. RESULTS: The expert panel reached consensus on CASE after four rounds. The final eight domains of the CASE included: pelvic lymph node dissection, development of the peri-ureteral space, lateral pelvic space, anterior rectal space, control of the vascular pedicle, anterior vesical space, control of the dorsal venous complex, and apical dissection. IRR > 0.6 was achieved for all eight domains. Experts outperformed trainees across all domains. CONCLUSION: We developed and validated a reliable structured, procedure-specific tool for objective evaluation of surgical performance during RARC. CASE may help differentiate novice from expert performances.

Tennessee emergency hand care distributions and disparities: Emergent hand care disparities.

BACKGROUND: Hand trauma is the most frequently treated injury in emergency departments, but presently there is a crisis of insufficient emergency coverage. This study evaluates the discrepancy of emergent and elective hand care trends based on socioeconomic factors in the state of Tennessee. METHODS: We identified 119 hospitals in Tennessee that contained operating and emergency room facilities. Of these, 111 hospitals participated in a survey to determine the availability of elective and emergency hand surgery. Wilcoxon rank-sum test or permutation chi-square test and logistic regression were used to analyze reported measures. RESULTS: Our results revealed that hospitals in counties with the lowest per capita income and median household income are less likely to have hand specialists or offer hand call. There are also significantly fewer hospitals that have hand specialists and offer hand call that are located in medically underserved areas. In the state of TN, level 1 trauma facilities are required by the Tennessee Department of Health to have staffed hand specialists and 24/7 hand call. Our study revealed that while 7/8 (87.5 %) level 1 trauma facilities have hand specialists, only 2/8 (25 %) provide 24/7 hand specialist call. CONCLUSION: Our results strongly suggest the presence of a health care disparity for hand trauma in counties with a low income and in medically underserved areas.
