Inpatient Resource Utilization for Hypoplastic Left Heart Syndrome from Birth Through Fontan

Completing 3-stage palliation for hypoplastic left heart syndrome requires significant resources. An analysis of recent data has not been performed. We aimed to determine total charges necessary to complete all 3 stages of single-ventricle palliation, including interstage encounters. We also aimed to determine overall resource utilization, including hospital days, interstage admissions, and interstage procedures. We performed a retrospective cohort study using data from the Pediatric Health Information System database between 2016 and 2021, including all patients who completed 3-stage palliation for hypoplastic left heart syndrome. We identified 199 patients who underwent 3-stage palliation of hypoplastic left heart syndrome between 2016 and 2021. Median total adjusted charges (interquartile range, IQR) over the course of 3-stage palliation were $1,475,800 ($1,028,900-2,191,700). Median adjusted charges (IQR) for stage 1, 2, and 3 hospitalizations were $604,300 ($419,000-891,400), $234,000 ($164,300-370,800), and $256,260 ($178,300-345,900), respectively. Median hospital length of stay (IQR) for stages 1, 2, and 3 was 36 (26,53), 9 (6,17), and 10 (7,14) days, respectively. Pulmonary artery stenosis was the most common admitting diagnosis for interstage hospitalizations (3.4% of hospitalizations). Cardiac catheterization (24.1% of procedures) and feeding tube placement (10.0% of procedures) were the most common principal procedures during interstage hospitalizations. Total inpatient charges incurred throughout 3-stage palliation of hypoplastic left heart syndrome are substantial and have risen since prior studies. Gastrointestinal comorbidities and feeding optimization contribute considerably to this resource utilization.

Disseminated Intravascular Coagulation in Acute Promyelocytic Leukemia Patients: A Retrospective Analysis of Outcomes and Healthcare Burden in US Hospitals

Objective

Acute promyelocytic leukemia (APL) is associated with an elevated risk of developing disseminated intravascular coagulation (DIC). The purpose of this study was to assess the outcomes of hospitalizations related to DIC in APL and their impact on healthcare.

Materials and Methods

This study entailed a cross-sectional and retrospective analysis of the US National Inpatient Sample database. We identified adults with APL and categorized them into groups of patients with and without DIC. Our focus areas included in-hospital mortality, length of stay, charges, and complications associated with DIC. Unadjusted odds ratios/coefficients were computed in univariate analysis, followed by adjusted odds ratios (aOR)/coefficients from multivariate analysis that accounted for confounding factors.

Results

Our analysis revealed that APL patients with DIC had a substantially higher aOR for mortality (aOR: 6.68, 95% confidence interval [CI]: 4.76-9.37, p<0.001) and a prolonged length of stay (coefficient: 10.28 days, 95% CI: 8.48-12.09, p<0.001) accompanied by notably elevated total hospital charges (coefficient: $215,512 [95% CI: 177,368-253,656], p<0.001), thereby emphasizing the reality of extended medical care and economic burden. The presence of DIC was associated with increased odds of sepsis, vasopressor support, pneumonia, acute respiratory failure, intubation/mechanical ventilation, and acute kidney injury, reflecting heightened vulnerability to these complications. Patients with DIC demonstrated significantly higher odds ratios for major bleeding, intracranial hemorrhage, gastrointestinal bleeding, red blood cell transfusion, platelet transfusion, fresh frozen plasma transfusion, and cryoprecipitate transfusion, highlighting the pronounced hematological risks posed by DIC.

Conclusion

This study has revealed the significant associations between DIC in APL and various outcomes, underscoring the clinical and economic implications of these conditions. The hematological risks further increase patients’ vulnerability to bleeding events and the need for transfusions.

Trends in Volume and Charges of Retinal Tear Patients in the Emergency Department

PURPOSE

To characterize retinal tears (RTs) and calculate the economic burden of RTs that present to the emergency department (ED) in the US.

METHODS

We used a large national ED database to retrospectively analyze RTs that presented to the ED from 2006 to 2019. Using extrapolation methods, national of the RT patient ED volume, demographics, comorbidities, disposition, inpatient (IP) charges, and ED charges were calculated.

RESULTS

During the period between 2006 and 2019, 15841 ED encounters had RT listed as the primary diagnosis. The average annual RT ED encounters was 2,640 ± 856 and comprised an average of 6.4 × 10 - 5 % of all ED visits annually. The number and ED percentage of RT encounters did not change during this time period (p = .22, p = .67, respectively). Most patients were males, Caucasian, paid with private insurance, and admitted to EDs in the Northeast. The most common comorbidities were hypertension (19%), a history of cataracts (15%), and diabetes (7.2%). During this time period, RTs charges added up to more than $79 million and $33 million in the ED and IP settings, respectively. Mean per-encounter ED and IP charges increased by 145% (p = .0008) and 86% (p = .0047), respectively.

CONCLUSION

Despite the stable number of RT patients presenting to the ED, RTs place a significant economic burden to the healthcare system, which increases yearly. We recommend physicians and policy makers to work together to pass laws that could prevent the increasing healthcare charges.

Trends, complications, and readmission of allogeneic red blood cell transfusion in primary total hip arthroplasty in china: a national retrospective cohort study

INTRODUCTION

Decrease in allogenic red blood cell (RBC) transfusion rates following total hip arthroplasty (THA) has been reported in the United States, but whether other countries share the same trend remains unclear. Additionally, the relation of allogenic RBC transfusion to the risk of complications in THA remains controversial. Using the Chinese national inpatient database, the current study aimed to examine trends, complications, charges, and readmission patterns of allogeneic RBC transfusion in THA.

MATERIALS AND METHODS

Patients undergoing primary THA between 2013 and 2019 were included, and then stratified into the transfusion and the non-transfusion group based on the database transfusion records. A generalized estimating equation model was used to investigate trends in transfusion rates. After propensity-score matching, a logistic regression model was used to compare the complications, rates and causes of 30-day readmission between two groups.

RESULTS

A total of 10,270 patients with transfusion and 123,476 patients without transfusion were included. Transfusion rates decreased from 19.11% in 2013 to 9.94% in 2019 (P for trend < 0.001). After matching, no significant differences in the risk of of in-hospital death (odds ratio [OR], 4.00; 95% confidence interval [CI] 0.85-18.83), wound infection (OR 0.72; 95%CI 0.45-1.17), myocardial infarction (OR 1.17; 95%CI 0.62-2.19), deep vein thrombosis (OR 1.25; 95%CI 0.88-1.78), pulmonary embolism (OR 2.25; 95%CI 0.98-5.17), readmission rates (OR 1.07; 95%CI 0.88-1.30) and readmission causes were observed between two groups. However, the transfusion group had higher hospitalization charges than the non-transfusion group (72,239.89 vs 65,649.57 Chinese yuan [CNY], P < 0.001).

CONCLUSIONS

This study found that allogeneic RBC transfusion in THA was not associated with the increased risk of complications and any-cause readmission. However, the currently restrictive transfusion policy should be continued because excessive blood transfusion may increase the socioeconomic burden.

Transcatheter Aortic Valve Replacement: Variations in Use, Charges, and Geography in the United States

The use of transcatheter aortic valve replacement (TAVR) in the United States has been increasing but with variability. We used a 100% sample of Medicare beneficiaries (MBs), from the Centers for Medicare and Medicaid Services database, who underwent TAVR by cardiologists between 2015 and 2019. We stratified data by geographic region, rural/urban areas, and provider's gender. We examined the average number of TAVRs performed per 100,000 MBs, the average number of TAVRs performed per individual cardiologist, and the average submitted charge (ASC) per procedure. The number of TAVR per 100,000 MBs was significantly variable among regions in all years (all P≤0.028), except in 2015 (P=0.103), with the highest rates being in the Northeast and the lowest being in the West. The number of TAVRs per cardiologist was significantly different among regions only in 2019 (P=0.04), with the Northeast showing the highest numbers and the South showing the lowest. The ASC was also significantly variable among regions in all years (all P≤0.01). The highest ASC was in the Midwest for all years, whereas the lowest was in the West in 2015 to 2016 and in the South in 2017 to 2019. In all years, the number of TAVRs per cardiologist was higher in urban areas than in rural areas (all P<0.05); however, rural cardiologists had higher ASCs (all P<0.05). The number of TAVR procedures per cardiologist was not significantly different between male and female cardiologists (all P>0.1). Female cardiologists had a significantly higher ASC only in 2015 (P=0.034). In conclusion, there are variations in TAVR use and charges for MBs according to geographic, urban, and rural regions and the performing cardiologist's gender.

The incidence of shoulder arthroplasty infection presents a substantial economic burden in the United States: a predictive model

Background

Periprosthetic joint infections (PJIs) are a major cause of morbidity after shoulder arthroplasty. Prior national database studies have estimated the trends of shoulder PJI up to 2012.²¹ Since 2012, the landscape of shoulder arthroplasty has changed drastically with the expanding popularity of reverse total shoulder arthroplasty. The dramatic growth in primary shoulder arthroplasties is likely paralleled with an increase of PJI case volume. The purpose of this study is to quantify the rise in shoulder PJIs and the economic stress they currently place on the American healthcare system as well as the toll they will incur over the coming decade.

Methods

The Nationwide Inpatient Sample database was queried for primary and revision anatomic total shoulder arthroplasty, reverse total shoulder arthroplasty, and hemiarthroplasty from 2011-2018. Multivariate regression was used to predict cases and charges through the year 2030 adjusted to 2021 purchasing power parity.

Results

From 2011 to 2018, PJI was found to be 1.1% shoulder arthroplasties, from 0.8% (2011) to 1.4% (2018). Anatomic total shoulder arthroplasty experienced the greatest proportion of infections at 2.0%, followed by hemiarthroplasty at 1.0% and reverse total shoulder arthroplasty at 0.3%. Total hospital charges grew 324%, from $44.8 million (2011) to $190.3 million (2018). Our regression model projects 176% growth in cases and 141% growth in annual charges by 2030.

Conclusion

This study demonstrates the large economic burden that shoulder PJIs pose on the American healthcare system, which is predicted to reach nearly $500 million in charges annually by 2030. Understanding trends in procedure volume and hospital charges will be critical in evaluating strategies to reduce shoulder PJIs.

Clinical and economic outcomes associated with intravenous albumin fluid use in the intensive care unit: a retrospective cohort study

OBJECTIVES

This study was undertaken to evaluate the prescribing practice of albumin in the intensive care unit (ICU) and to compare the clinical and economic outcomes associated with intravenous (IV) albumin compared to crystalloids in the ICU.

METHODS

This was a retrospective cohort study of ICU adult patients admitted to King Abdullah University Hospital during 2018-2019. Patient demographics, clinical characteristics, and admission charges were retrieved from medical records and billing system. Survival analysis, multivariable regression models, and propensity score matching estimator were performed to evaluate the impact of IV resuscitation fluid types on the clinical and economic outcomes.

RESULTS

Albumin administration in the ICU was associated with significantly lower hazards of ICU death (HR = 0.57; P value <0.001), but without improving overall death probability compared to crystalloids. Albumin was associated with significant prolongation in the ICU length of stay (5.86 days; P value <0.001). Only 88 patients (24.3%) were prescribed albumin for Food and Drug Administration (FDA)-approved indications. Admission charges were significantly higher for patients treated with albumin (p value <0.001).

CONCLUSIONS

IV Albumin use in the ICU was not associated with significant improvement in clinical outcomes, but with a remarkable increase in economic burden. The majority of patients received albumin for non-FDA-approved indications.

Informing traffic enforcement leniency and discretion: Crash culpability and the effectiveness of written warnings versus citations

OBJECTIVES

Deterrence of risky driving behavior is important for the prevention of crashes and injuries. Traffic law enforcement is a key strategy used to decrease risky driving, but there is little evidence on the deterrent effect of issuing warnings versus citations to drivers regarding the prevention of future crashes. The purpose of this study was to 1) investigate the difference between citations and written warnings in their association with future crash culpability and 2) investigate whether drivers who were issued written warnings or citations have different associations with future crash culpability likelihood than those without prior citations or written warnings.

METHODS

Data for this study included Iowa Department of Transportation crash data for 2016 to 2019 linked to data from the Iowa Court Case Management System. A quasi-induced exposure method was used based on driver pairs involved in the same collision in which one driver was deemed culpable and one was non-culpable. Conditional logistic regression models were constructed to examine predictors of crash culpability. The main independent variable was traffic citation and warnings history categorized into moving warning, non-moving warning, moving citation, non-moving citation, or no citation or warning in the 30 days prior to the crash.

RESULTS

The study sample included a total of 152,986 drivers. Among drivers with moving violations, previously cited drivers were more likely to be crash culpable than previously warned drivers (OR = 1.64, 95% CI = 1.29-2.08). Drivers with prior non-moving citations were less likely to be the culpable party in a crash than a driver who had no recent warnings or citations (OR = 0.72, 95% CI = 0.58-0.89). Drivers with prior warnings (moving or non-moving) did not appreciably differ in crash culpability relative to drivers who had not received any citations or warnings in the previous 30 days.

CONCLUSIONS

Drivers with prior moving citations were more likely to be culpable in a future crash than drivers with prior moving warnings, which may relate to overall driving riskiness as opposed to effectiveness of citations in deterring risky driving behaviors. Results from this study also suggest that officer discretion was being appropriately applied by citing the riskiest drivers, while giving lower risk drivers warnings. Results from this study may be useful to support strengthening of state driver improvement programming.

Limited evidence that emergency department care is more costly than other outpatient settings for low-acuity conditions: a systematic review

PURPOSE

Caring for patients with low-acuity conditions in Emergency Departments (ED) is often thought to cost more than treating those patients in other ambulatory settings. Understanding the relative cost of care between settings has critical implications for healthcare policy and system design.

METHODS

We conducted a systematic review of papers comparing the cost of care for low-acuity and ambulatory care sensitive conditions in ED and other outpatient settings. We searched PubMed, EMBASE, CINAHL, and Web of Science for peer reviewed papers, plus Google for grey literature. We conducted duplicate screening and data extraction, and quality assessment of included studies using an adapted SIGN checklist for economic studies. We calculated an unweighted mean charge ratio across studies and summarized our findings in narrative and tabular format.

RESULTS

We identified one study comparing costs. 18 studies assessed physician or facility charges, conducted in the United States, United Kingdom, and Canada, including cohort analyses (5), charge analyses (5), survey (1), and database searches (5) assessing populations ranging from 370 participants to 60 million. Charge ratios ranged from 0.60 to 13.45 with an unweighted mean of 4.20. Most (12) studies were of acceptable quality.

CONCLUSION

No studies since 2001 assess the comparative costs of ED versus non-ED care for low-acuity ambulatory conditions. Physician and facility charges for ED care are higher than in other ambulatory settings for low-acuity conditions. Empirical evidence is lacking to support that ED care is more costly than similar care in other ambulatory settings.

The significance of bioelectricity on all levels of organization of an organism. Part 1: From the subcellular level to cells

Bioelectricity plays an essential role in the structural and functional organization of biological organisms. In this first article of our three-part series, we summarize the importance of bioelectricity for the basic structural level of biological organization, i.e. from the subcellular level (charges, ion channels, molecules and cell organelles) to cells.

Trends in charges and association with defaults on medical payments in uninsured Americans: a disproportionate burden in ethnic minorities - a retrospective observational study

OBJECTIVE

To evaluate whether medical event charges are associated with uninsured patients' probability of medical payment default and whether there exist racial/ethnic disparity gaps in medical payment defaults.

DESIGN

We use logistic regression models to analyse medical payment defaults. Our adjusted estimates further control for a rich set of patient and medical visit characteristics, region and time fixed effects.

SETTING

Uninsured US adult (non-elderly) population from 2002 to 2017.

PARTICIPANTS

We use four nationally representative samples of uninsured patients from the Medical Expenditure Panel Survey across office-based (n=39 967), emergency (n=3269), outpatient (n=1739) and inpatient (n=340) events.

PRIMARY AND SECONDARY OUTCOME MEASURES

Payment default, medical event charges and medical event payments.

RESULTS

Relative to uninsured non-Hispanic white (NHW) patients, uninsured non-Hispanic black (NHB) patients are 142% (p<0.01) more likely to default on medical payments for office-based visits, 27% (p<0.05) more likely to default on emergency department visit payments and 82% (p<0.1) more likely to default on an outpatient visit bill. Hispanic patients are 46% (p<0.01) more likely to default on an office-based visit, but 25% less likely to default on emergency department visit payments than NHW patients. Within our fully adjusted model, we find that racial/ethnic disparities persist for office-based visits. Our results further suggest that the probabilities of payment defaults for office-based, emergency and outpatient visits are all significantly (p<0.01) and positively associated with the medical event charges billed.

CONCLUSIONS

Medical event charges are found to be broadly associated with payment defaults, and we further note disproportionate payment default disparities among NHB patients.

Increasing medicare charge-to-payment ratios for dermatologists from 2012 to 2017

Government-backed medical insurance plans have undergone significant changes in the last decade, but more information is needed to understand reimbursement trends, particularly for specialist medical services. The objective of this study was to identify the ratios of submitted dermatology service charges to allowed Medicare payments over the years. Further variables studied include regional or state variations, gender of provider, hierarchical condition category (HCC) risk scores of patient complexity, and number of services. Data were collected from publicly available Medicare Part B Provider Utilization and Payment Data: Physician and Other Supplier 2012-2017 datasets. All data analysis was performed on SAS 9.4 Statistical Software.Total dermatology related medicare charges-to-payment ratios steadily increased over the years (1.77 [in 2012], 1.82 [2013], 1.87 [2014], 1.95 [2015], 2.02 [2016], and 2.06 [2017]). This suggests that for every $2.06 charged in 2017, dermatology providers could expect $1 of actual payment. When further stratified into medical services vs. drug services, this upward trend remained for medical charges but drug service ratios have remained constant. There was also significant geographic variation in total medicare charges-to-payment ratios as states in the Midwest (mean total ratio: 2.48) had higher charges to payment gaps than states in the Northeast (2.26), West (2.16), and South (1.99; p = 0.01).This study identifies trends and variables associated with dermatology medicare payments. Providers may use this information to better understand changing payment structures in their own practices and hopefully these results can be valuable in future policy discussions.

Significance of Hospital Size in Outcomes of Single-Level Elective Anterior Cervical Discectomy and Fusion: A Nationwide Readmissions Database Analysis

OBJECTIVE

To elucidate risk factors for 90-day readmission in anterior cervical discectomy and fusion (ACDF) for small, medium, and large hospitals. To assess differences in length of stay, charges, and complication rates across hospitals of different size.

METHODS

A retrospective analysis was performed using elective, single-level ACDF data from 2016 to 2018 in the Healthcare Cost and Utilization Project Nationwide Readmissions Database. Elective single-level ACDF cases were stratified into 3 groups by hospital bed size (small, medium, and large). All-cause complication rates, mean charges, length of stay, and 90-day readmission rates were compared across hospital size. Frequencies of specific comorbidities were compared between readmitted and nonreadmitted patients for each hospital size. Comorbidities significant on univariate analysis were evaluated as independent risk factors for 90-day readmission for each hospital size using multivariate regression.

RESULTS

The overall 90-day readmission rate was 6.43% in 36,794 patients, and the rates for small, medium, and large hospitals were 6.25%, 6.28%, and 6.56%, respectively (P = 0.537). Length of stay increased significantly with hospital size (P < 0.001), and small hospitals had the lowest charges (P < 0.001). Although different independent predictors of 90-day readmission were identified for each hospital size, cardiac arrhythmia, chronic pulmonary disease, neurologic disorders, and rheumatic disease were identified as risk factors for hospitals of all sizes.

CONCLUSIONS

Hospital size is a determining factor for charges and length of stay associated with elective single-level ACDF. Variation in risk factors for readmission exists across hospital size in context of similar 90-day readmission rates.

Dermatomyositis and polymyositis in total hip arthroplasty

BACKGROUND

Idiopathic inflammatory myopathies (IIM) are systemic autoimmune disorders such as dermatomyositis (DM), polymyositis (PM), inclusion body myopathy, and autoimmune necrotizing myopathy that, similar to osteoarthritis, affect quality of life and activities of daily living. Moreover, these patients are often burdened with chronic pain and disability; however, the outcomes and risk of total hip arthroplasty (THA) in this patient population remain unclear.

AIM

To evaluate 90-d complications and costs in patients with these conditions.

METHODS

A retrospective case control study was designed by accessing data from the Medicare dataset available on the PearlDiver server. Patients with IIM, here, those with DM and PM were matched based on possible confounding variables to a cohort without these diseases and with the same 10-year risk of mortality as defined by the Charlson Comorbidity Index Score (CCI). Univariate and multivariate analysis were performed to evaluate complications and t-tests to evaluate 90-d Medicare reimbursements as markers of costs after THA.

RESULTS

The total sample was 1090 patients with each cohort comprised of 545. Females were 74.9% of the population. The mean CCI was 5.89 (SD 2.11). Those with IIM had increased rates of pneumonia [odds ratio (OR) 1.45, P < 0.001] and pulmonary embolism (OR 1.46, P = 0.035) and decreased hematoma risks (OR 0.58, P = 0.00). 90-d costs were on average $1411 greater for those with IIM yet not significantly different (P = 0.034).

CONCLUSION

Patients with IIM have an increased 90-d rate of pneumonia and pulmonary embolism concomitant with a decreased hematoma rate consistent with their pro-coagulatory state. Further attention to increased resource utilization in these patients is also warranted.

Water-based carbodiimide mediated synthesis of polysaccharide-amino acid conjugates: Deprotection, charge and structural analysis

We report here a one-step aqueous method for the synthesis of isolated and purified polysaccharide-amino acid conjugates. Two different types of amino acid esters: glycine methyl ester and L-tryptophan methyl ester, as model compounds for peptides, were conjugated to the polysaccharide carboxymethylcellulose (CMC) in water using carbodiimide at ambient conditions. Detailed and systematic pH-dependent charge titration and spectroscopy (infrared, nuclear magnetic resonance: ¹H, ¹³C- DEPT 135, ¹H- ¹³C HMBC/HSQC correlation), UV-vis, elemental and ninhydrin analysis provided solid and direct evidence for the successful conjugation of the amino acid esters to the CMC backbone via an amide bond. As the concentration of amino acid esters increased, a conjugation efficiency of 20-80% was achieved. Activated charcoal aided base-catalyzed deprotection of the methyl esters improved the solubility of the conjugates in water. The approach proposed in this work should have the potential to tailor the backbone of polysaccharides containing di- or tri-peptides.

Fast track dialysis: Improving emergency department and hospital throughput for patients requiring hemodialysis

OBJECTIVE

To describe the impact of a novel communication and triage pathway called fast track dialysis (FTD) on the length of stay (LOS), resource utilization, and charges for unscheduled hemodialysis for end stage renal disease (ESRD) patients presenting to the emergency department (ED).

METHODS

Prospective and retrospective cohorts of ESRD patients meeting requirements of routine or urgent hemodialysis at a tertiary academic hospital from September 25th, 2016 to September 25th, 2018 in 1 year cohorts. Two sample t-tests were used to compare most outcomes of the cohorts with a Mann-Whitney U test used for skewed data. Nephrology group outcomes were analyzed by two-way ANOVA and Kruskal-Wallis and chi-square tests.

RESULTS

There were 98 encounters in the historical cohort and 143 encounters in the fast track dialysis cohort. FTD had significantly lowered median ED LOS (4.05 h, vs 5.3 h, p < 0.001), median hospital LOS (12.8 h vs 27 h, p < 0.001), time to hemodialysis (4.78 h vs 7.29 h, p < 0.001), and median hospital charges ($26,040 vs $30,747, p < 0.016). The FTD cohort had increased 30 day ED return for each encounter compared to the historical cohort (1.85 visits vs 0.73 visits, p < 0.001), however no significant increase in 1 year ED visits (6.52 visits vs 5.80, p = 0.4589) or 1 year readmissions (5.89 readmissions vs 4.81 readmissions, p = 0.3584). Most nephrology groups had significantly lower time to hemodialysis order placement and time to start hemodialysis.

CONCLUSION

A multidisciplinary approach with key stakeholders using a standard pathway can lead to improved efficiency in throughput, reduced charges, and hospital resource utilization for patients needing urgent or routine hemodialysis. A study with a dedicated geographic observation unit for protocolized short stay patients including conditions ranging from low risk chest pain to transient ischemic events that incorporates FTD patients under this protocol should be considered.

Estimation of healthcare-related charges in women with BRCA mutations and breast cancer

Background

Breast cancer costs were estimated at $16.5 billion in 2010 and were higher than other cancer costs. There are limited studies on breast cancer charges and costs by BRCA mutations and receptor status. We examined overall health care and breast cancer-related charges by BRCA status (BRCAm vs. BRCAwt), receptor status (HER2+ vs. HER2-), and treatment setting (neoadjuvant vs. adjuvant).

Methods

Retrospective cohort study of charge data from 1995-2014 in an academic medical center. Facilities, physician, pharmacy, and diagnosis-related charges were presented as mean and median charges with standard deviation (SD) and interquartile ranges (25%-75%). Wilcoxon rank-sum test was used to assess statistically significant differences in charges between comparators.

Results

Total median breast-cancer related charges were $65,414 for BRCAm and $54,635 for BRCAwt (p=0.19); however all-cause charges were higher for BRCAm patients ($145,066 vs. $119,119, p<0.001). HER2+ status was associated with higher median breast cancer charges ($152,159 vs. $44,087, p<0.0001) that was driven by the charges for biological agents. Patients initially seen in the neoadjuvant setting had higher mean breast cancer charges than in the adjuvant setting ($117,922 vs. $80,061, p<0.0001).

Conclusion

BRCA mutation status was not associated with higher breast cancer charges but HER2+ status had significantly higher charges, due to charges for biological agents. Patients who initially received neoadjuvant treatment had significantly higher overall treatment charges than adjuvant therapy patients. With the advent of novel therapies for BRCAm, the economic impact of these treatments will be important to consider relative to their survival benefits.

The 5-factor modified frailty index predicts health burden following surgery for pituitary adenomas

PURPOSE

Frailty is known to influence cost-related surgical outcomes in neurosurgery, but quantifying frailty is often challenging. Therefore, we investigated the predictive value of the 5-factor modified frailty index (mFI-5) on total hospital charges, LOS, and 90-day readmission for patients undergoing pituitary surgery.

METHODS

The medical records of all patients undergoing endoscopic endonasal resection of pituitary adenomas at an academic medical center between January 2017 and December 2018 were retrospectively reviewed. Bivariate statistical analyses were conducted using Fisher's exact test, chi-square test, and independent samples t-test. Linear and logistic regression models were used for multivariate analysis.

RESULTS

Our cohort (n = 234) had a mean age of 53.8 years (standard deviation 14.6 years). Sex distributions were equal, and most patients were Caucasian (59%). On multivariate linear regression, with each one-point increase in mFI-5, total LOS increased by 0.64 days in the overall cohort (p < 0.001), 1.08 days in the Cushing disease cohort (p = 0.045), and 0.59 days in non-functioning tumors cohort (p = 0.004). Total charges increased by $3954 in the whole cohort (p < 0.001), $10,652 in the Cushing disease cohort (p = 0.033), and $2902 in the non-functioning tumors cohort (p = 0.007) with each one-point increase in mFI-5. Greater mFI-5 scores were associated with greater odds of 90-day readmission in both overall and Cushing disease cohorts, but these associations did not reach statistical significance.

CONCLUSION

A patient's mFI-5 score is significantly associated with increased length of stay and hospital charges for patients undergoing pituitary surgery. The mFI-5 may hold peri-operative value in patient counseling for pituitary adenoma surgery.

Pediatric pneumonia: An analysis of cost & outcome influencers in the United States

BACKGROUND

Pediatric pneumonia is a significant cause of inpatient care in the United States. Significant resource utilization and the high cost of care necessitate careful evaluation, especially with continuously decreasing financial resources. Several studies have evaluated subsets and regional impact of these diagnoses, but only a few have evaluated these on a national level.

METHODS

This retrospective analysis utilized the 2009-2012 HCUP KID Inpatient Dataset to evaluate the relationship between pneumonia diagnosis and factors affecting cost for patients between 0 and 21. One hundred forty-five thousand one hundred forty-six patients' charges with primary pneumonia diagnosis were evaluated based on LOS, chronic conditions, severity, mortality and region.

RESULTS

Majority of cases of diagnosis were of unspecified organism: 11,4811 (78%) of the total population. RSV-related pneumonia diagnosis presented second with a total of 8,156 (5.5%). Charges for pneumonia in the Emergency Department (ER) were about $13,104 and non-ER presentation at $10,238. LOS affected total charge and mortality risk for all patient population regardless of age.

CONCLUSION

This nationwide study provides a unique preview of the cost associated with care for pediatric pneumonia. Such information is essential in developing strategies to improve health outcomes and resources allocation.

Increasing Burden of Hepatic Encephalopathy Among Hospitalized Adults: An Analysis of the 2010-2014 National Inpatient Sample

BACKGROUND

Hepatic encephalopathy (HE) is associated with substantial morbidity and mortality, contributing significant burden on healthcare systems.

AIM

We aim to evaluate trends in clinical and economic burden of HE among hospitalized adults in the USA.

METHODS

Using the 2010-2014 National Inpatient Sample, we identified adults hospitalized with HE using ICD-9-CM codes. Annual trends in hospitalizations with HE, in-hospital mortality, and hospital charges were stratified by the presence of acute liver failure (ALF) or cirrhosis. Adjusted multivariable regression models were evaluated for predictors of in-hospital mortality and hospitalization charges.

RESULTS

Among 142,860 hospitalizations with HE (mean age 59.3 years, 57.8% male), 67.7% had cirrhosis and 3.9% ALF. From 2010 to 2014, total number of hospitalizations with HE increased by 24.4% (25,059 in 2010 to 31,182 in 2014, p < 0.001). Similar increases were seen when stratified by ALF (29.7% increase) and cirrhosis (29.7% increase). Overall in-hospital mortality decreased from 13.4% (2010) to 12.3% (2014) (p = 0.001), with similar decreases observed in ALF and cirrhosis. Total inpatient charges increased by 46.0% ($8.15 billion, 2010 to $11.9 billion, 2014). On multivariable analyses, ALF was associated with significantly higher odds of in-hospital mortality (OR 5.37; 95% CI 4.97-5.80; p < 0.001) as well as higher mean inpatient charges (122.6% higher; 95% CI + 115.0-130.3%; p < 0.001) compared to cirrhosis. The presence of ascites, hepatocellular carcinoma, and hepatorenal syndrome was associated with increased mortality.

CONCLUSIONS

The clinical and economic burden of hospitalizations with HE in the USA continues to rise. In 2014, estimated national economic burden of hospitalizations with HE reached $11.9 billion.

Charges for Alcoholic Cirrhosis Exceed All Other Etiologies of Cirrhosis Combined: A National and State Inpatient Survey Analysis

BACKGROUND

Inpatient charges for patients with cirrhosis are substantial. We aimed to examine trends in inpatient charges among patients with cirrhosis to determine the drivers of healthcare expenditures. We hypothesized that alcoholic cirrhosis (AC) was a significant contributor to overall expense.

METHODS

We performed a retrospective analysis of the Health Care Utilization Project Nationwide Inpatient Sample Database 2002-2014 (annual cross-sectional data) and New York and Florida State Inpatient Databases 2010-2012 (longitudinal data). Adult patients with cirrhosis of the liver were categorized as AC versus all other etiologies of cirrhosis combined. Patient characteristics were analyzed using ordinary least squares regression modeling. A random effects model was used to evaluate 30-day readmissions.

RESULTS

In total, 1,240,152 patients with cirrhosis were admitted between 2002 and 2014. Of these, 567,510 (45.8%) had a diagnosis of AC. Total charges for AC increased by 95.7% over the time period, accounting for 59.9% of all inpatient cirrhosis-related charges in 2014. Total aggregate charges for AC admissions were $28 billion and increased from $1.4B in 2002 to $2.8B by 2014. In the NIS and SID, patients with AC were younger, white and male. Readmission rates at 30, 60, and 90 days were all higher among AC patients.

CONCLUSIONS

Inpatient charges for cirrhosis care are high and increasing. Alcohol-related liver disease accounts for more than half of these charges and is driven by sheer volume of admissions and readmissions of the same patients. Effective alcohol addictions therapy may be the most cost-effective way to substantially reduce inpatient cirrhosis care expenditures.

Evaluating intensive care unit medication charges in a teaching hospital in Jordan

Background: Intensive Care Unit (ICU) medication costs contribute to a large portion of the total ICU costs. Evaluating ICU drug expenditures is essential for optimal resource use especially in countries with limited resources. Considering the dearth of data regarding ICU medication expenses in the Middle East, we sought to evaluate ICU medication charges at a large academic hospital in Jordan. Methods: ICU drug charges were extracted from the hospital administration database at King Abdullah University Hospital for 2014-2015 fiscal years (FYs). ICU drug charges were compared to non-ICU drug charges that were incurred during the same patient admissions. ICU medications with the most significant charges were identified. The most frequent diagnoses with the highest ICU medication charges were described. Results: Average ICU medication charges per day were approximately twice that of non-ICU medication charges ($121.5 versus $55.7 in 2014 and $100.2 versus $52.2 in 2015; p < 0.001 in both FYs). Meropenem and human albumin were the most expensive ICU medications. Drug charge allocation was most expensive for sepsis, motor vehicle accidents and respiratory failure. Conclusion: Drug charges in the ICU are considerably higher than non-ICU drug charges, thus requiring more vigilant cost containment approaches. Further research is needed to evaluate the appropriateness of expensive ICU medications.

Use of the burn intervention score to calculate the charges of the care of burns

BACKGROUND

To our knowledge this is the first published estimate of the charges of the care of burns in Sweden. The Linköping Burn Interventional Score has been used to calculate the charges for each burned patient since 1993. The treatment of burns is versatile, and depends on the depth and extension of the burn. This requires a flexible system to detect the actual differences in the care provided. We aimed to describe the model of burn care that we used to calculate the charges incurred during the acute phase until discharge, so it could be reproduced and applied in other burn centres, which would facilitate a future objective comparison of the expenses in burn care.

METHODS

All patients admitted with burns during the period 2010-15 were included. We analysed clinical and economic data from the daily burn scores during the acute phase of the burn until discharge from the burn centre.

RESULTS

Total median charge/patient was US$ 28 199 (10th-90th centiles 4668-197 781) for 696 patients admitted. Burns caused by hot objects and electricity resulted in the highest charges/TBSA%, while charges/day were similar for the different causes of injury. Flame burns resulted in the highest mean charges/admission, probably because they had the longest duration of stay. Mean charges/patient increased in a linear fashion among the different age groups.

CONCLUSION

Our intervention-based estimate of charges has proved to be a valid tool that is sensitive to the procedures that drive the costs of the care of burns such as large TBSA%, intensive care, and operations. The burn score system could be reproduced easily in other burn centres worldwide and facilitate the comparison regardless of the differences in the currency and the economic circumstances.

Knee dislocation with popliteal artery disruption: A nationwide analysis from 2005 to 2013

Objective

Few have compared short-term outcomes following knee dislocations with or without concomitant popliteal artery disruption (PAD).

Methods

The Nationwide Inpatient Sample was used to identify 2175 patients admitted for knee dislocation from 2005 to 2013 (concomitant PAD: n = 210/9.7%; without: n = 1965/90.3%).

Results

Patients with PAD were younger, more often male, Black and Hispanic, and with Medicaid (all p ≤ 0.013). PADs were associated with 11.0-times higher odds of increased LOS (95%CI, 6.6-18.4) and 2.8-times higher odds of experiencing any complication (95%CI, 2.03-3.92). Female sex was a protective factor against increased LOS, (OR = 0.65; 95%CI, 0.48-0.88).

Conclusion

High suspicion index should be maintained for concomitant vascular injuries following knee dislocations.

Surgeon variation in operating times and charges for emergency general surgery

BACKGROUND

Patients and hospitals face significant financial burdens from emergency general surgeries (EGSs), which have been termed a public health crisis in the United States. We evaluated hospitalization charges, operating charges, and variations in operating time by surgeon volume for three common EGS procedures.

METHODS

Using Maryland's Health Services Cost Review Commission database, we performed a retrospective study of laparoscopic appendectomies, laparoscopic cholecystectomies, and open bowel resections performed by general surgeons among adult patients from July 2012 to September 2014. We compared operating charges to total hospitalization charges and quantified variations in operating time for each procedure. We then divided patients into quartiles based on their surgeon's procedure-specific case volume and used hierarchical linear regressions to calculate differences in both operating time and charges between quartiles.

RESULTS

We identified 3194 appendectomies, 4143 cholecystectomies, and 1478 bowel resections. Operating charges accounted for one-quarter (26.9%) of total hospitalization charges and widespread variation existed in operating time (appendectomies: median 79 min [interquartile range 66-100 min], cholecystectomies: 96 min [76-125 min], bowel resections: 155 min [117-209 min]). After adjustment, low-volume surgeons relative to high-volume surgeons did not operate statistically longer for appendectomies (+1%, 95% confidence interval [CI]: -2% to 5%) but operated +16% (95% CI: 12%-20%) longer for cholecystectomies (+14 min) and +40% (95% CI: 30%-50%) longer for bowel resections (+59 min). Adjusted median operating charges from low-volume surgeons relative to high-volume surgeons were $554 (26.7%), $621 (22.0%), and $1801 (47.0%) greater for appendectomies, cholecystectomies, and bowel resections, respectively.

CONCLUSIONS

Operating charges contributed substantially to total EGS hospitalization charges, where low-volume surgeons operated longer and had higher operative charges relative to high-volume surgeons. Reducing variations in operating times and charges represents an opportunity to alleviate the financial burden from EGS procedures.

Utilization patterns of extracorporeal membrane oxygenation in neonates in the United States 1997-2012

BACKGROUND

Extracorporeal membrane oxygenation (ECMO) remains one of the most intensive therapies for newborns in the United States. However, there is limited information on resource utilization for neonates receiving ECMO.

METHODS

We conducted a retrospective data analysis of the Kids' Inpatient Database from 1997 to 2012. Bivariate and multivariate analysis was completed to identify predictors of LOS, hospital costs and mortality. Cardiac and non-cardiac diagnoses of neonates receiving ECMO were also included in the bivariate and multivariable analysis.

RESULTS

Of the 5151 ECMO cases, survival to discharge was 62%. 22% had a principal cardiac diagnosis. After adjusting for covariates, increased mortality was associated with treatment in the midwest compared to the northeast region (aOR=2.0, p<0.01) and decreased among neonates with a non-cardiac diagnosis (aOR=0.4, p<0.01). Living in midwest was associated with longer LOS by 13days and increased hospital costs by 63,000 dollars (p<0.01). When stratified by non-cardiac diagnoses, infants with a diagnosis of congenital diaphragmatic hernia was associated with increased mortality (2.3, p<0.01) and longer LOS (25, p<0.01) and increased costs (11,100, p<0.01).

CONCLUSION

Neonates who received ECMO in certain regions of the United States were associated with poorer survival outcomes as well as increased LOS and hospital costs.

The financial impact and drivers of hospital charges in contralateral prophylactic mastectomy and reconstruction: a Nationwide Inpatient Sample hospital analysis

PURPOSE

Rates of contralateral prophylactic mastectomy (CPM) have increased over the last decade; it is important for surgeons and hospital systems to understand the economic drivers of increased costs in these patients. This study aims to identify factors affecting charges in those undergoing CPM and reconstruction.

METHODS

Analysis of the Healthcare Cost and Utilization Project National Inpatient Sample was undertaken (2009-2012), identifying women aged ≥18 with unilateral breast cancer undergoing unilateral mastectomy with CPM and immediate breast reconstruction (IBR) (CPM group), in addition to unilateral mastectomy and IBR alone (UM group). Generalized linear modeling with gamma regression and a log-link function provided mean marginal hospital charge (MMHC) estimates associated with the presence or absence of patient, hospital and operative characteristics, postoperative complications, and length of stay (LOS).

RESULTS

Overall, 70,695 women underwent mastectomy and reconstruction for unilateral breast cancer; 36,691 (51.9%) in the CPM group, incurring additional MMHCs of $20,775 compared to those in the UM group (p < 0.001). In the CPM group, MMHCs were reduced in those aged >60 years (p < 0.001), while African American or Hispanic origin increased MMHCs (p < 0.001). Diabetes, depression, and obesity increased MMHCs (p < 0.001). MMHCs increased with larger (p < 0.001) hospitals, Western location (p < 0.001), greater household income (p < 0.001), complications (p < 0.001), and increasing LOS (p < 0.001). MMHCs decreased in urban teaching hospitals and Midwest or Southern regions (p < 0.001).

CONCLUSION

There are many patient and hospital factors affecting charges; this study provides surgeons and hospital systems with transparent, quantitative charge data in patients undergoing contralateral prophylactic mastectomy and immediate breast reconstruction.

Open Access Publishing in the Field of Medical Informatics

The open access paradigm has become an important approach in today’s information and communication society. Funders and governments in different countries stipulate open access publications of funded research results. Medical informatics as part of the science, technology and medicine disciplines benefits from many research funds, such as National Institutes of Health in the US, Wellcome Trust in UK, German Research Foundation in Germany and many more. In this study an overview of the current open access programs and conditions of major journals in the field of medical informatics is presented. It was investigated whether there are suitable options and how they are shaped. Therefore all journals in Thomson Reuters Web of Science that were listed in the subject category “Medical Informatics” in 2014 were examined. An Internet research was conducted by investigating the journals’ websites. It was reviewed whether journals offer an open access option with a subsequent check of conditions as for example the type of open access, the fees and the licensing. As a result all journals in the field of medical informatics that had an impact factor in 2014 offer an open access option. A predominantly consistent pricing range was determined with an average fee of 2.248 € and a median fee of 2.207 €. The height of a journals’ open access fee did not correlate with the height of its Impact Factor. Hence, medical informatics journals have recognized the trend of open access publishing, though the vast majority of them are working with the hybrid method. Hybrid open access may however lead to problems in questions of double dipping and the often stipulated gold open access.

National Trends in the Surgical Management of Adolescent Idiopathic Scoliosis: Analysis of a National Estimate of 60,108 Children From the National Inpatient Sample Over a 13-Year Time Period in the United States

STUDY DESIGN

Analysis of Nationwide Inpatient Sample (NIS).

OBJECTIVE

Evaluate evolution of operative treatment of adolescent idiopathic scoliosis (AIS).

SUMMARY OF BACKGROUND DATA

Spinal surgery is one of the most rapidly evolving branches of surgery. Changes in AIS operations are incompletely defined.

METHODS

Children (10-18 years) with ICD-9 diagnosis of idiopathic scoliosis who underwent thoracic and/or lumbar spinal fusion identified in the NIS (1998-2011) were analyzed. Population-based utilization rates were calculated from US Census data. Patient demographics, surgical approach, operative techniques, complications during hospitalization, hospital stay length, and charges were analyzed.

RESULTS

60,108 children (46,256 girls, 13,776 boys, 76 gender not specified; average age 14.1 years) were identified. Thoracic fusions were the majority. Number of operations increased over time. For thoracic fusions, posterior operations significantly increased, whereas anterior and anterior/posterior operations decreased significantly. Although anterior operations for lumbar fusions declined, this was not as steep as thoracic. Use of autogenous bone graft (including iliac crest) significantly increased, which mirrored significant decreases in alternative fusion agents. Thoracoplasty significantly decreased, whereas osteotomy significantly increased. The average complication rate was 3.7%. Rates of blood transfusions, infection, and neural injury did not differ significantly from 1998 to 2011. Device-related complications increased significantly over time. Average lengths of hospital stay decreased significantly, whereas average total hospital charges increased significantly.

CONCLUSIONS

In a representative sample of the US population from 1998 to 2011, operative approaches and techniques for AIS significantly changed. Anterior procedure is rarely performed for thoracic curves; lumbar curves continue to be treated with anterior and posterior approaches. Osteotomy and autogenous bone graft increased, while thoracoplasty decreased. Overall complication rates remain stable, whereas hospital lengths of stays decreased and charges increased.

Charges associated with imaging techniques in evaluation of pediatric hearing loss

OBJECTIVE

The best imaging study for evaluation of pediatric hearing loss is debated and it is well known magnetic resonance imaging is more costly than computed tomography. The objective of this study is to evaluate charges of computed tomography temporal bone (CTTB) versus magnetic resonance imaging brain, internal auditory canal/cerebellopontine angle (MRI IAC/CPA), with and without sedation in the pediatric population in order to assess to what extent the charges for the procedure are increased. In addition, differences in need for sedation and duration of sedation will be evaluated.

METHODS

All patients, 0-18 years that underwent CTTB or MRI IAC/CPA, between January 2013 through December 2014 within department of otolaryngology.

RESULTS

120 CTTBs (118 non-sedated and 2 sedated) and 51 MRI IAC/CPAs (32 non-sedated and 19 sedated) were performed. Average charge for non-sedated CTTB was $1856. CTTB scan under sedation incurred total additional charges of $2385. Average charges for non-sedated MRI IAC/CPA was $3770. Technical charges for sedated MRI IAC/CPA was $151 lower ($2858) but had additional sedation charges of $2256, a recovery room charge of $250, and additional professional fees of $1496 for total charges of $7621. 37% of MRI IAC/CPAs needed sedation to be completed in comparison to 1.6% of CTTB.

CONCLUSION

MRI IAC/CPAs are, on average, twice as costly as CTTBs. Almost 40% of patients need sedation to complete MRI IAC/CPA. These considerations may factor into decision making when choosing imaging modality in evaluation of pediatric hearing loss.

Geographic variation in cost of care for pituitary tumor surgery

PURPOSE

Geography is known to affect cost of care in surgical procedures. Understanding the relationship between geography and hospital costs is pertinent in the effort to reduce healthcare costs. We studied the geographic variation in cost for transsphenoidal pituitary surgery in hospitals across New York State.

METHODS

Using the Healthcare Cost and Utilization Project State Inpatient Database for New York from 2008 to 2011, we analyzed records of patients who underwent elective transsphenoidal pituitary tumor surgery and were discharged to home or self-care. N.Y. State was divided into five geographic regions: Buffalo, Rochester, Syracuse, Albany, and Downstate. These five regions were compared according to median charge and cost per day.

RESULTS

From 2008 to 2011, 1803 transsphenoidal pituitary tumor surgeries were performed in New York State. Mean patient age was 50.7 years (54 % were female). Adjusting prices for length of stay, there was substantial variation in prices. Median charges per day ranged from $8485 to $13,321 and median costs per day ranged from $2962 to $6837 between the highest and lowest regions from 2008 to 2011.

CONCLUSION

Within New York State, significant geographic variation exists in the cost for transsphenoidal pituitary surgery. The significance of and contributors to such variation is an important question for patients, providers, and policy makers. Transparency of hospital charges, costs, and average length of stay for procedures to the public provides useful information for informed decision-making, especially for a highly portable disease entity like pituitary tumors.

Emergency Department and Inpatient Healthcare utilization due to Hypertension

Background

Hypertension is one of the commonest chronic diseases, yet limited data are available for related health care utilization. Our study objective was to describe the emergency department (ED) and subsequent hospitalization related health care utilization and charges due to hypertension in the U.S.

Methods

We used the National ED sample (NEDS) to study hypertension-related utilization and charges. Multivariable-adjusted linear or logistic regression was used to assess hypertension-associated ED and hospitalization outcomes (disposition, length of stay, charges), adjusted for patient demographic, comorbidity and hospital characteristics.

Results

There were 0.92, 0.97 and 1.04 million ED visits (0.71–0.77 % of all ED visits) with hypertension as the primary diagnosis in 2009, 2010 and 2012, respectively; 23 % resulted in hospitalization. ED charges were $2.00, $2.27 and $2.86 billion, and for those hospitalized, total charges (ED plus inpatient) were $6.62, $7.09 and $7.94 billion, in 2009, 2010 and 2012, respectively. Older age (50 to 65 years), female sex, metropolitan area residence, South or West U.S. hospital location, private insurance and the presence of congestive heart failure were each associated with higher charges for an ED visit with hypertension as the primary diagnosis. Younger age, metropolitan residence, Medicaid insurance, hospital location in the Northeast and co-existing diabetes, gout, coronary heart disease, chronic obstructive pulmonary disease, hyperlipidemia and osteoarthritis were associated with higher risk, whereas male sex was associated with lower risk of hospitalization after ED visit for hypertension. In 2012, 71.6 % of all patients hospitalized with hypertension as the primary diagnosis were discharged home. Older age, metropolitan residence and most comorbidities were associated with lower odds, whereas male sex, payer other than Medicare, South or West U.S. hospital location were associated with higher odds of discharge to home.

Conclusions

Hypertension is associated with significant healthcare burden in the U.S. Future studies should assess strategies to reduce hypertension-associated cost and health care burden.

Distribution and predictors of emergency department charges: the case of a tertiary hospital in Lebanon

Background

As health care costs continue to increase worldwide, health care systems, and more specifically hospitals are facing continuous pressure to operate more efficiently. One service within the hospital sector whose cost structure has been modestly investigated is the Emergency Department (ED). The study aims to report on the distribution of ED resource use, as expressed in charges, and to determine predictors of/contributors to total ED charges at a major tertiary hospital in Lebanon.

Methods

The study used data extracted from the ED discharge database for visits between July 31, 2012 and July 31, 2014. Patient visit bills were reported under six major categories: solutions, pharmacy, laboratory, physicians, facility, and radiology. Characteristics of ED visits were summarized according to patient gender, age, acuity score, and disposition. Univariate and multivariate analyses were conducted with total charges as the dependent variable.

Results

Findings revealed that the professional fee (40.9 %) followed by facility fee (26.1 %) accounted for the majority of the ED charges. While greater than 80 % of visit charges went to physician and facility fee for low acuity cases, these contributed to only 52 and 54 % of the high acuity presentations where ancillary services and solutions’ contribution to the total charges increased. The total charges for males were $14 higher than females; age was a predictor of higher charges with total charges of patients greater than 60 years of age being around $113 higher than ages 0–18 after controlling for all other variables.

Conclusion

Understanding the components and determinants of ED charges is essential to developing cost-containment interventions. Institutional modeling of charging patterns can be used to offer price estimates to ED patients who request this information and ultimately help create market competition to drive down costs.

Motorcycle helmet effectiveness in reducing head, face and brain injuries by state and helmet law

Background

Despite evidence that motorcycle helmets reduce morbidity and mortality, helmet laws and rates of helmet use vary by state in the U.S.

Methods

We pooled data from eleven states: five with universal laws requiring all motorcyclists to wear a helmet, and six with partial laws requiring only a subset of motorcyclists to wear a helmet. Data were combined in the Crash Outcome Data Evaluation System’s General Use Model and included motorcycle crash records probabilistically linked to emergency department and inpatient discharges for years 2005-2008. Medical outcomes were compared between partial and universal helmet law settings. We estimated adjusted relative risks (RR) and 95 % confidence intervals (CIs) for head, facial, traumatic brain, and moderate to severe head/facial injuries associated with helmet use within each helmet law setting using generalized log-binomial regression.

Results

Reported helmet use was higher in universal law states (88 % vs. 42 %). Median charges, adjusted for inflation and differences in state-incomes, were higher in partial law states (emergency department $1987 vs. $1443; inpatient $31,506 vs. $25,949). Injuries to the head and face, including traumatic brain injuries, were more common in partial law states. Effectiveness estimates of helmet use were higher in partial law states (adjusted-RR (CI) of head injury: 2.1 (1.9-2.2) partial law single vehicle; 1.4 (1.2, 1.6) universal law single vehicle; 1.8 (1.6-2.0) partial law multi-vehicle; 1.2 (1.1-1.4) universal law multi-vehicle).

Conclusions

Medical charges and rates of head, facial, and brain injuries among motorcyclists were lower in universal law states. Helmets were effective in reducing injury in both helmet law settings; lower effectiveness estimates were observed in universal law states.

Down Syndrome Increases the Risk of Short-Term Complications After Total Hip Arthroplasty

BACKGROUND

Down syndrome is the most common chromosomal abnormality and is associated with degenerative hip disease. Because of the recent increase in life expectancy for patients with this syndrome, orthopaedic surgeons are likely to see an increasing number of these patients who are candidates for total hip arthroplasty (THA).

METHODS

Using Nationwide Inpatient Sample (NIS) data from 1998 to 2010, we compared the short-term adverse outcomes of THA among 241 patients with Down syndrome and a matched 723-patient cohort. Specifically, we assessed: (1) incidence of THA; (2) perioperative medical and surgical complications during the primary hospitalization; (3) length of stay; and (4) hospital charges.

RESULTS

The annual mean number of patients with Down syndrome undergoing THA was 19. Compared to matched controls, Down syndrome patients had an increased risk of perioperative (OR, 4.33; P<.001), medical (OR, 4.59; P<.001) and surgical (OR, 3.51; P<.001) complications during the primary hospitalization. Down syndrome patients had significantly higher incidence rates of pneumonia (P=.001), urinary tract infection (P<.001), and wound hemorrhage (P=.027). The mean lengths of stay for Down syndrome patients were 26% longer (P<.001), but there were no differences in hospital charges (P=.599).

CONCLUSION

During the initial evaluation and pre-operative consultation for a patient with Down syndrome who is a candidate for THA, orthopaedic surgeons should educate the patient, family and their clinical decision makers about the increased risk of medical complications (pneumonia and urinary tract infections), surgical complications (wound hemorrhage), and lengths of stay compared to the general population.

Charges, outcomes, and complications: a comparison of magnetic sphincter augmentation versus laparoscopic Nissen fundoplication for the treatment of GERD. Surg Endosc. 2016;30:3225-3230. [PMID: 26541730 DOI: 10.1007/s00464-015-4635-6]

BACKGROUND

Magnetic sphincter augmentation (MSA) is approved for uncomplicated GERD. Multiple studies have shown MSA to compare favorably to laparoscopic Nissen fundoplication (LNF) in terms of symptom control with results out to 5 years. The MSA device itself, however, is an added cost to an anti-reflux surgery, and direct cost comparison studies have not been done between MSA and LNF. The aim of the study was to compare charges, complications, and outcome of MSA versus LNF at 1 year.

METHODS

This is a retrospective analysis of all patients who underwent MSA or LNF for the treatment of GERD between January 2010 and June 2013. Patient charges were collected for the surgical admission. We also collected data on 30-day complications and symptom control at 1 year assessed by GERD-HRQL score and PPI use.

RESULTS

There were 119 patients included in the study, 52 MSA and 67 LNF. There was no significant difference between the mean charges for MSA and LNF ($48,491 vs. $50,111, p = 0.506). There were significant differences in OR time (66 min MSA vs. 82 min LNF, p < 0.01) and LOS (17 h MSA vs. 38 h LNF, p < 0.01). At 1-year follow-up, mean GERD-HRQL was 4.3 for MSA versus 5.1 for LNF (p = 0.47) and 85 % of MSA patients versus 92 % of LNF patients were free from PPIs (p = 0.37). MSA patients reported less gas bloat symptoms (23 vs. 53 %, p ≤ 0.01) and inability to belch (10 vs. 36 %, p ≤ 0.01) and vomit (4 vs. 19 %, p ≤ 0.01).

CONCLUSION

The side effect profile of MSA is better than LNF as evidenced by less gas bloat and increase ability to belch and vomit. LNF and MSA are comparable in symptom control, safety, and overall hospital charges. The charge for the MSA device is offset by less charges in other categories as a result of the shorter operative time and LOS.

The cost of injury: hospital charges for pregnant trauma patients, 1999 to 2003

BACKGROUND

Traumatic injuries during pregnancy are the leading cause of nonobstetric maternal mortality. We aimed to determine hospital charges for trauma activations during pregnancy.

METHODS

We used the Illinois State Trauma Registry data from 1999 to 2003. Using STATA for bivariate and regression analyses, we compared total hospital costs for women more than 24 weeks pregnant with nonpregnant women.

RESULTS

Six hundred thirty-five pregnant women (2.4% of 26,806 female trauma patients) were admitted during the study period. In multivariate regression, pregnancy was associated with lower hospital charges; however, for any given length of stay, pregnancy increased hospital charges (α = $17,864.80, P = .001). Pregnancy also independently predicted increased length of stay for similar injury severity.

CONCLUSIONS

When controlling for injury severity, pregnancy independently predicted an increased duration of hospitalization and hospital charges. These findings have important implications for resource allocation and care of trauma in pregnancy.
