PURPOSE - Standardized care via a unified surgeon preference card for pediatric appendectomy can result in significant cost reduction. The purpose of this study was to evaluate the impact of cost and outcome feedback to surgeons on value of care in an environment reluctant to adopt a standardized surgeon preference card.
METHODS - Prospective observational study comparing operating room (OR) supply costs and patient outcomes for appendectomy in children with 6-month observation periods both before and after intervention. The intervention was real-time feedback of OR supply cost data to individual surgeons via automated dashboards and monthly reports.
RESULTS - Two hundred sixteen children underwent laparoscopic appendectomy for non-perforated appendicitis (110 pre-intervention and 106 post-intervention). Median supply cost significantly decreased after intervention: $884 (IQR $705-$1025) to $388 (IQR $182-$776), p<0.001. No significant change was detected in median OR duration (47min [IQR 36-63] to 50min [IQR 38-64], p=0.520) or adverse events (1 [0.9%] to 6 [4.7%], p=0.062). OR supply costs for individual surgeons significantly decreased during the intervention period for 6 of 8 surgeons (87.5%).
CONCLUSION - Approaching value measurement with a surgeon-specific (rather than group-wide) approach can reduce OR supply costs while maintaining excellent clinical outcomes.

Measuring the Value of a Clinical Practice Guideline for Children With Perforated Appendicitis.
Robinson JR, Avritscher EBC, Gay JC, Willis ZI, Putnam LR, Anglemyer A, Pedroza C, Tyson JE, Blakely ML
(2017) Ann Surg 266: 195-200
MeSH Terms: Abdominal Abscess, Anti-Bacterial Agents, Appendectomy, Appendicitis, Child, Cost Savings, Cost-Benefit Analysis, Female, Hospital Costs, Humans, Intestinal Perforation, Male, Postoperative Complications, Practice Guidelines as Topic
Show Abstract · Added January 16, 2017
OBJECTIVE - To determine the incremental cost-effectiveness of a clinical practice guideline (CPG) compared with "usual care" for treatment of perforated appendicitis in children. Secondary objective was to compare cost analyses using hospital accounting system data versus data in the Pediatric Health Information System (PHIS).
BACKGROUND - Value-based surgical care (outcomes relative to costs) is frequently touted, but outcomes and costs are rarely measured together.
METHODS - During an 18-month period, 122 children with perforated appendicitis at a tertiary referral children's hospital were treated using an evidence-based CPG. Clinical outcomes and costs for the CPG cohort were compared with patients in the 30-month period before CPG implementation (n = 191 children).
RESULTS - With CPG-directed care, intra-abdominal abscess rate decreased from 0.24 to 0.10 (adjusted risk ratio 0.44, 95% confidence interval [CI] 0.26-0.75). The rate of any adverse event decreased from 0.30 to 0.23 (adjusted risk ratio 0.82, 95% CI 0.58-1.17). Mean total hospital costs per patient (hospital accounting system) decreased from $16,466 to $10,528 (adjusted absolute difference-$5451, 95% CI -$7755 to -$3147), leading to estimated adjusted total savings of $665,022 during the study period. Costs obtained from the PHIS database also showed reduction with CPG-directed care (-$6669, 95% CI -$8949 to -$4389 per patient). In Bayesian cost-effectiveness analyses, likelihood that CPG was the dominant strategy was 91%.
CONCLUSIONS - An evidence-based CPG increased the value of surgical care for children with perforated appendicitis by improving outcomes and lowering costs. Hospital cost accounting data and pre-existing cost data within the PHIS database provided similar results.

Hemiepiphysiodesis Implants for Late-onset Tibia Vara: A Comparison of Cost, Surgical Success, and Implant Failure.
Funk SS, Mignemi ME, Schoenecker JG, Lovejoy SA, Mencio GA, Martus JE
(2016) J Pediatr Orthop 36: 29-35
MeSH Terms: Adolescent, Bone Diseases, Developmental, Child, Costs and Cost Analysis, Female, Hospital Costs, Humans, Male, Orthopedic Procedures, Osteochondrosis, Prosthesis Design, Prosthesis Failure, Retrospective Studies, Tibia, Treatment Outcome
Show Abstract · Added February 22, 2016
BACKGROUND - The purpose of this study was to compare hemiepiphysiodesis implants for late-onset tibia vara and to evaluate patient characteristics that may predict surgical failure.
METHODS - This is a retrospective review of late-onset tibia vara patients treated with temporary hemiepiphysiodesis from 1998 to 2012. Mechanical axis deviation (MAD), mechanical axis angle, mechanical lateral distal femoral angle, and medial proximal tibial angle were measured on standing bone length radiographs. Surgical failure was defined as residual deformity requiring osteotomy, revision surgery, or MAD exceeding 40 mm at the time of final follow-up. Implant failure was recorded. Costs included implants and disposables required for construct placement. Staple constructs included 2 or 3 staples. Plate constructs included the plate, screws, guide wires, and drill bits.
RESULTS - A total of 25 patients with 38 temporary lateral proximal tibia hemiepiphysiodeses met the inclusion criteria. The average body mass index (BMI) was 39.1 kg/m with an average follow-up of 3.0 years (minimum 1 y). Surgical failure occurred in 57.9% of patients. Greater BMI (P=0.05) and more severe deformity (MAD, mechanical axis angle, and medial proximal tibial angle; P<0.01) predicted higher rates of surgical failure. Younger age predicted higher rates of implant failure (P<0.01). There were no differences in surgical or implant failure between staple and plate systems. Hospital costs of plate constructs ($781 to $1244) were 1.5 to 3.5 times greater than the staple constructs ($332 to $498).
CONCLUSIONS - Greater BMI, more severe deformity, and younger age were predictive of surgical or implant failure. There was no difference in success between implant types, whereas the cost of plate constructs was 1.5 to 3.5 times greater than staples. The rate of surgical failure was high (58%) and consideration should be given to reserving hemiepiphysiodesis for patients with lower BMI and less severe deformity. In our population, if hemiepiphysiodesis was not offered to patients with BMI>35 or MAD>80 mm varus, the surgical failure rate would diminish to 28%. The failure rate outside these parameters would be 88%.

Rodby R, Umanath K, Niecestro R, Jackson JH, Sika M, Lewis JB, Dwyer JP, Collaborative Study Group
(2015) Expert Rev Pharmacoecon Outcomes Res 15: 545-50
MeSH Terms: Adult, Chelating Agents, Cost Savings, Ferric Compounds, Hospital Costs, Hospitalization, Humans, Kidney Failure, Chronic, Phosphorus, Renal Dialysis
Show Abstract · Added January 30, 2015
BACKGROUND - Ferric citrate (FC) is a new phosphorus binder shown to increase serum iron stores while reducing intravenous iron and erythropoiesis-stimulating agent usage. Such reductions could lower hospitalization rates and associated costs.
METHODS - Hospitalizations during a Phase III trial were compared between FC and active control (AC). Hospitalization costs were estimated using the 2013 US Renal Data System Annual Data Report.
RESULTS - 34.6% of FC patients were hospitalized at least once versus 45.6% of the AC group (risk reduction 24.2%; p = 0.02). There were 181 unique hospitalizations in the FC group versus 239 in the AC group, for a difference of 58 hospitalizations. Total potential savings was US$ 867,622 in hospitalization costs in the FC group. If the hospitalization reduction in our study was applied to the general end-stage renal disease population, this could translate into a savings of US$ 3002/patient/year.
CONCLUSIONS - Patients receiving FC experienced fewer hospitalizations with the potential for significant savings.

Show Abstract · Added May 29, 2014
SETTING - A large randomized controlled trial recently showed that for treating latent tuberculous infection (LTBI) in persons at high risk of progression to tuberculosis (TB) disease, a 12-dose regimen of weekly rifapentine plus isoniazid (3HP) administered as directly observed treatment (DOT) can be as effective as 9 months of daily self-administered isoniazid (9H).
OBJECTIVES - To assess the cost-effectiveness of 3HP compared to 9H.
DESIGN - A computational model was designed to simulate individuals with LTBI treated with 9H or 3HP. Costs and health outcomes were estimated to determine the incremental costs per active TB case prevented and per quality-adjusted life year (QALY) gained by 3HP compared to 9H.
RESULTS - Over a 20-year period, treatment of LTBI with 3HP rather than 9H resulted in 5.2 fewer cases of TB and 25 fewer lost QALYs per 1000 individuals treated. From the health system and societal perspectives, 3HP would cost respectively US$21,525 and $4294 more per TB case prevented, and respectively $4565 and $911 more per QALY gained.
CONCLUSIONS - 3HP may be a cost-effective alternative to 9H, particularly if the cost of rifapentine decreases, the effectiveness of 3HP can be maintained without DOT, and 3HP treatment is limited to those with a high risk of progression to TB disease.

Show Abstract · Added June 14, 2016
BACKGROUND - Numerous studies have supported the effectiveness of recombinant activated factor VII (rFVIIa) for the control of bleeding after cardiac procedures; however safety concerns persist. Here we report the novel use of intraoperative low-dose rFVIIa in thoracic aortic operations, a strategy intended to improve safety by minimizing rFVIIa exposure.
METHODS - Between July 2005 and December 2010, 425 consecutive patients at a single referral center underwent thoracic aortic operations with cardiopulmonary bypass (CPB); 77 of these patients received intraoperative low-dose rFVIIa (≤60 μg/kg) for severe coagulopathy after CPB. Propensity matching produced a cohort of 88 patients (44 received intraoperative low-dose rFVIIa and 44 controls) for comparison.
RESULTS - Matched patients receiving intraoperative low-dose rFVIIa got an initial median dose of 32 μg/kg (interquartile range [IQR], 16-43 μg/kg) rFVIIa given 51 minutes (42-67 minutes) after separation from CPB. Patients receiving intraoperative low-dose rFVIIa demonstrated improved postoperative coagulation measurements (partial thromboplastin time 28.6 versus 31.5 seconds; p=0.05; international normalized ratio, 0.8 versus 1.2; p<0.0001) and received 50% fewer postoperative blood product transfusions (2.5 versus 5.0 units; p=0.05) compared with control patients. No patient receiving intraoperative low-dose rFVIIa required postoperative rFVIIa administration or reexploration for bleeding. Rates of stroke, thromboembolism, myocardial infarction, and other adverse events were equivalent between groups.
CONCLUSIONS - Intraoperative low-dose rFVIIa led to improved postoperative hemostasis with no apparent increase in adverse events. Intraoperative rFVIIa administration in appropriately selected patients may correct coagulopathy early in the course of refractory blood loss and lead to improved safety through the use of smaller rFVIIa doses. Appropriately powered randomized studies are necessary to confirm the safety and efficacy of this approach.

Frisse ME, Johnson KB, Nian H, Davison CL, Gadd CS, Unertl KM, Turri PA, Chen Q
(2012) J Am Med Inform Assoc 19: 328-33
MeSH Terms: Adult, Cost Savings, Electronic Health Records, Emergency Service, Hospital, Female, Health Care Costs, Hospital Costs, Humans, Logistic Models, Male, Medical Record Linkage, Models, Econometric, Outcome Assessment (Health Care), Patient Admission, Tennessee, Unnecessary Procedures
Show Abstract · Added January 20, 2015
OBJECTIVE - To examine the financial impact health information exchange (HIE) in emergency departments (EDs).
MATERIALS AND METHODS - We studied all ED encounters over a 13-month period in which HIE data were accessed in all major emergency departments Memphis, Tennessee. HIE access encounter records were matched with similar encounter records without HIE access. Outcomes studied were ED-originated hospital admissions, admissions for observation, laboratory testing, head CT, body CT, ankle radiographs, chest radiographs, and echocardiograms. Our estimates employed generalized estimating equations for logistic regression models adjusted for admission type, length of stay, and Charlson co-morbidity index. Marginal probabilities were used to calculate changes in outcome variables and their financial consequences.
RESULTS - HIE data were accessed in approximately 6.8% of ED visits across 12 EDs studied. In 11 EDs directly accessing HIE data only through a secure Web browser, access was associated with a decrease in hospital admissions (adjusted odds ratio (OR)=0.27; p<0001). In a 12th ED relying more on print summaries, HIE access was associated with a decrease in hospital admissions (OR=0.48; p<0001) and statistically significant decreases in head CT use, body CT use, and laboratory test ordering.
DISCUSSION - Applied only to the study population, HIE access was associated with an annual cost savings of $1.9 million. Net of annual operating costs, HIE access reduced overall costs by $1.07 million. Hospital admission reductions accounted for 97.6% of total cost reductions.
CONCLUSION - Access to additional clinical data through HIE in emergency department settings is associated with net societal saving.

Outpatient versus inpatient observation after percutaneous native kidney biopsy: a cost minimization study.
Maripuri S, Penson DF, Ikizler TA, Cavanaugh KL
(2011) Am J Nephrol 34: 64-70
MeSH Terms: Ambulatory Care, Biopsy, Needle, Blood Transfusion, Cost Control, Hospital Costs, Hospitalization, Humans, Kidney, Kidney Diseases, Liability, Legal, Postoperative Hemorrhage, Probability
Show Abstract · Added March 5, 2014
BACKGROUND/AIMS - Percutaneous kidney biopsy (PKB) is the primary diagnostic tool for kidney disease. Outpatient 'day surgery' (ODS) following PKB in low-risk patients has previously been described as a safe alternative to inpatient observation (IO). This study aims to determine if ODS is less costly compared to IO while accounting for all institutional costs (IC) associated with post-PKB complications, including death.
METHODS - A cost minimization study was performed using decision analysis methodology which models relative costs in relation to outcome probabilities yielding an optimum decision. The potential outcomes included major complications (bleeding requiring blood transfusion or advanced intervention), minor complications (bleeding or pain requiring additional observation), and death. Probabilities were obtained from the published literature and a base case was selected. IC were obtained for all complications from institutional activity-based cost estimates. The base case assumed a complication rate of 10% with major bleeding occurring in 2.5% of patients (for both arms) and death in 0.1 and 0.15% of IO and ODS patients, respectively.
RESULTS - ODS costs USD 1,394 per biopsy compared to USD 1,800 for IO inclusive of all complications. IC for ODS remain less when overall complications <20%, major complications <5.5%, and IC per death CONCLUSION - Outpatient management after PKB for low-risk patients costs less from the institutional perspective compared to IO, inclusive of complications and death. ODS should be considered for low-risk patients undergoing native kidney biopsy.

Show Abstract · Added December 10, 2013
This study determined direct medical costs for influenza-associated hospitalizations and emergency department (ED) visits. For 3 influenza seasons, children <5 years of age with laboratory-confirmed influenza were identified through population-based surveillance. The mean direct cost per hospitalized child was $5402, with annual cost burden estimated at $44 to $163 million. Factors associated with high-cost hospitalizations included intensive care unit (ICU) admission and having an underlying high-risk condition. The mean medical cost per ED visit was $512, with annual ED cost burden estimated at $62 to $279 million. Implementation of the current vaccination policies will likely reduce the cost burden.

New insights into the role of anabolic interventions in dialysis patients with protein energy wasting.
Dong J, Ikizler TA
(2009) Curr Opin Nephrol Hypertens 18: 469-75
MeSH Terms: Anabolic Agents, Combined Modality Therapy, Cost Savings, Cost-Benefit Analysis, Drug Costs, Enteral Nutrition, Hospital Costs, Humans, Parenteral Nutrition, Protein-Energy Malnutrition, Renal Dialysis, Resistance Training, Treatment Outcome
Show Abstract · Added September 29, 2014
PURPOSE OF REVIEW - Patients on maintenance dialysis commonly develop protein-energy wasting (PEW), which is associated with poor survival. There have been several advances in anabolic interventions aimed at improving PEW in these patients in recent years.
RECENT FINDINGS - Oral or parenteral nutritional supplementation, especially if administered during dialysis, improves net protein anabolism in chronic hemodialysis patients. These beneficial effects have been extended to long-term benefits in recent clinical trials. Resistance exercise, alone or combined with intradialytic oral nutrition supplementation, also improves net protein balance in the acute setting although recent studies indicated a limited beneficial effect of long-term exercise alone on muscle protein accretion in chronic hemodialysis patients. Anabolic agents such as growth hormone and androgens have been shown to exert significant benefits on visceral protein stores, muscle mass and strength. Ghrelin, a hormone with combined orexigenic and anti-inflammatory effects, is a potential new nutritional intervention in maintenance dialysis patients.
SUMMARY - Existing anabolic therapeutic strategies have proven to be effective in improving PEW in maintenance dialysis patients. Combined anabolic interventions and several new and established anabolic hormones represent further promising nutritional interventions. Large-scale randomized controlled trials examining the effects of anabolic interventions on mortality and morbidity are still lacking.
