Multicenter Assessment of Cryoanalgesia Use in Minimally Invasive Repair of Pectus Excavatum: A 20-center Retrospective Cohort Study.

OBJECTIVE: To assess the clinical implications of cryoanalgesia for pain management in children undergoing minimally invasive repair of pectus excavatum (MIRPE). BACKGROUND: MIRPE entails significant pain management challenges, often requiring high postoperative opioid use. Cryoanalgesia, which blocks pain signals by temporarily ablating intercostal nerves, has been recently utilized as an analgesic adjunct. We hypothesized that the use of cryoanalgesia during MIRPE would decrease postoperative opioid use and length of stay (LOS). MATERIALS AND METHODS: A multicenter retrospective cohort study of 20 US children's hospitals was conducted of children (age below 18 years) undergoing MIRPE from January 1, 2014, to August 1, 2019. Differences in total postoperative, inpatient, oral morphine equivalents per kilogram, and 30-day LOS between patients who received cryoanalgesia versus those who did not were assessed using bivariate and multivariable analysis. P value <0.05 is considered significant. RESULTS: Of 898 patients, 136 (15%) received cryoanalgesia. Groups were similar by age, sex, body mass index, comorbidities, and Haller index. Receipt of cryoanalgesia was associated with lower oral morphine equivalents per kilogram (risk ratio=0.43, 95% confidence interval: 0.33-0.57) and a shorter LOS (risk ratio=0.66, 95% confidence interval: 0.50-0.87). Complications were similar between groups (29.8% vs 22.1, P =0.07), including a similar rate of emergency department visit, readmission, and/or reoperation. CONCLUSIONS: Use of cryoanalgesia during MIRPE appears to be effective in lowering postoperative opioid requirements and LOS without increasing complication rates. With the exception of preoperative gabapentin, other adjuncts appear to increase and/or be ineffective at reducing opioid utilization. Cryoanalgesia should be considered for patients undergoing this surgery.

Post-Trial Sustainability and Scalability of the Benefits of a Medical Home for High-Risk Children with Medical Complexity.

OBJECTIVE: To assess the sustainability of the benefits relative to usual care of a medical home providing comprehensive care for high-risk children with medical complexity (≥2 hospitalizations or ≥1 pediatric intensive care unit [PICU] admission in the year before enrollment) after we made comprehensive care our standard practice and expanded the program. STUDY DESIGN: We conducted pre-post comparisons of the rate of children with serious illness (death, PICU admission, or >7-day hospitalization) and health-system costs observed after program expansion (March 2014-June 2015) to those during the clinical trial (March 2011-August 2013) for each of the trial's treatment groups (usual care, n = 96, and comprehensive care, n = 105; primary analyses), and among all children given comprehensive care (nPost-trial = 233, including trial usual care children who transitioned to comprehensive care post-trial and newly enrolled medically complex children, and nTrial = 105; secondary analyses). We also analyzed the findings for the trial patients as a 2-phase stepped-wedge study. RESULTS: In intent-to-treat analyses, rates of children with serious illness and costs were reduced or unchanged post-trial vs trial for the trial's usual care group (rate ratio [RR], 0.36; 95% CI, 0.20-0.64; cost ratio [CR], 0.68; 95% CI, 0.28-1.68), the trial's comprehensive care group (RR, 0.74; 95% CI, 0.39-1.41; CR, 0.67; 95% CI, 0.51-0.89), and among all children given comprehensive care (RR, 0.97; 95% CI, 0.61-1.52; CR, 0.75; 95% CI, 0.61-0.93). Conservative stepped-wedge analyses identified overall benefits with comprehensive care across both study periods (RR, 0.46; 95% CI, 0.30-0.72; CR, 0.64; 95% CI, 0.43-0.99). CONCLUSIONS: Major benefits of comprehensive care did not diminish with post-trial program expansion.

Measuring the Value of a Clinical Practice Guideline for Children With Perforated Appendicitis.

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.

Serious postoperative infections following resection of common solid tumors: outcomes, costs, and impact of hospital surgical volume.

PURPOSE: Unlike infections related to chemotherapy-induced neutropenia, postoperative infections occurring in patients with solid malignancy remain largely understudied. Our aim is to evaluate the outcomes and the volume-outcomes relationship associated with postoperative infections following resection of common solid tumors. METHODS: We used Texas Discharge Data to study patients undergoing resection of cancer of the lung, esophagus, stomach, pancreas, colon, or rectum from 01/2002 to 11/2006. From their billing records, we identified ICD-9 codes indicating a diagnosis of serious postoperative infection (SPI), i.e., bacteremia/sepsis, pneumonia, and wound infection, occurring during surgical admission or leading to readmission within 30 days of surgery. Using regression-based techniques, we estimated the impact of SPI on mortality, resource utilization, and costs, as well as the relationship between hospital volume and SPI, after adjusting for confounders and data clustering. RESULTS: SPI occurred following 9.4 % of the 37,582 eligible tumor resections and was independently associated with nearly 12-fold increased odds of in-hospital mortality [95 % confidence interval (95 % CI), 7.2-19.5, P < 0.001]. Patients with SPI required six additional hospital days (95 % CI, 5.9-6.2) at an incremental cost of $16,991 (95 % CI, $16,495-$17,497). Patients who underwent resection at high-volume hospitals had a 16 % decreased odds of developing SPI than those at low-volume hospitals (P = 0.03). CONCLUSIONS: Due to the substantial burden associated with SPI following common solid tumor resections, hospitals must identify more effective prophylactic measures to avert these potentially preventable infections. Additional volume-outcomes research is needed to identify infection prevention processes that can be transferred from high- to lower-volume providers.

Effect of an enhanced medical home on serious illness and cost of care among high-risk children with chronic illness: a randomized clinical trial.

IMPORTANCE: Patient-centered medical homes have not been shown to reduce adverse outcomes or costs in adults or children with chronic illness. OBJECTIVE: To assess whether an enhanced medical home providing comprehensive care prevents serious illness (death, intensive care unit [ICU] admission, or hospital stay >7 days) and/or reduces costs among children with chronic illness. DESIGN, SETTING, AND PARTICIPANTS: Randomized clinical trial of high-risk children with chronic illness (≥3 emergency department visits, ≥2 hospitalizations, or ≥1 pediatric ICU admissions during previous year, and >50% estimated risk for hospitalization) treated at a high-risk clinic at the University of Texas, Houston, and randomized to comprehensive care (n = 105) or usual care (n = 96). Enrollment was between March 2011 and February 2013 (when predefined stopping rules for benefit were met) and outcome evaluations continued through August 31, 2013. INTERVENTIONS: Comprehensive care included treatment from primary care clinicians and specialists in the same clinic with multiple features to promote prompt effective care. Usual care was provided locally in private offices or faculty-supervised clinics without modification. MAIN OUTCOMES AND MEASURES: Primary outcome: children with a serious illness (death, ICU admission, or hospital stay >7 days), costs (health system perspective). Secondary outcomes: individual serious illnesses, medical services, Medicaid payments, and medical school revenues and costs. RESULTS: In an intent-to-treat analysis, comprehensive care decreased both the rate of children with a serious illness (10 per 100 child-years vs 22 for usual care; rate ratio [RR], 0.45 [95% CI, 0.28-0.73]), and total hospital and clinic costs ($16,523 vs $26,781 per child-year, respectively; cost ratio, 0.58 [95% CI, 0.38-0.88]). In analyses of net monetary benefit, the probability that comprehensive care was cost neutral or cost saving was 97%. Comprehensive care reduced (per 100 child-years) serious illnesses (16 vs 44 for usual care; RR, 0.33 [95% CI, 0.17-0.66]), emergency department visits (90 vs 190; RR, 0.48 [95% CI, 0.34-0.67]), hospitalizations (69 vs 131; RR, 0.51 [95% CI, 0.33-0.77]), pediatric ICU admissions (9 vs 26; RR, 0.35 [95% CI, 0.18-0.70]), and number of days in a hospital (276 vs 635; RR, 0.36 [95% CI, 0.19-0.67]). Medicaid payments were reduced by $6243 (95% CI, $1302-$11,678) per child-year. Medical school losses (costs minus revenues) increased by $6018 (95% CI, $5506-$6629) per child-year. CONCLUSIONS AND RELEVANCE: Among high-risk children with chronic illness, an enhanced medical home that provided comprehensive care to promote prompt effective care vs usual care reduced serious illnesses and costs. These findings from a single site of selected patients with a limited number of clinicians require study in larger, broader populations before conclusions about generalizability to other settings can be reached.

Povidone-iodine intra-abdominal irrigation versus no irrigation in pediatric perforated appendicitis: A secondary economic analysis of a Bayesian randomized controlled trial.

BACKGROUND: A pilot randomized controlled trial (RCT) conducted in children (2-17 â€‹y) with perforated appendicitis demonstrated an 89% probability of reduced intra-abdominal abscess (IAA) rate with povidone-iodine (PVI) irrigation, compared with no irrigation (NI). We hypothesized that PVI also reduced 30-day hospital costs. METHODS: We conducted a retrospective economic analysis of a pilot RCT. Hospital costs, inflated to 2019 U.S. dollars, were obtained for index admissions and 30-day emergency visits and readmissions. Cost differences between groups were assessed using frequentist and Bayesian generalized linear models. RESULTS: We observed a 95% Bayesian probability that PVI reduced 30-day mean total hospital costs ($16,555 [PVI] versus $18,509 [NI]; Bayesian cost ratio: 0.90, 95% CrI, 0.78-1.03). The mean absolute difference per patient was $1,954 less with PVI (95% CI, -$4,288 to $379). CONCLUSIONS: PVI likely reduced the IAA rate and 30-day hospital costs, suggesting the intervention is both clinically superior and cost saving.

Hospital-Level NICU Capacity, Utilization, and 30-Day Outcomes in Texas.

Importance: Risk-adjusted neonatal intensive care unit (NICU) utilization and outcomes vary markedly across regions and hospitals. The causes of this variation are poorly understood. Objective: To assess the association of hospital-level NICU bed capacity with utilization and outcomes in newborn cohorts with differing levels of health risk. Design, Setting, and Participants: This population-based retrospective cohort study included all Medicaid-insured live births in Texas from 2010 to 2014 using linked vital records and maternal and newborn claims data. Participants were Medicaid-insured singleton live births (LBs) with birth weights of at least 400 g and gestational ages between 22 and 44 weeks. Newborns were grouped into 3 cohorts: very low birth weight (VLBW; <1500 g), late preterm (LPT; 34-36 weeks' gestation), and nonpreterm newborns (NPT; ≥37 weeks' gestation). Data analysis was conducted from January 2022 to October 2023. Exposure: Hospital NICU capacity measured as reported NICU beds/100 LBs, adjusted (ie, allocated) for transfers. Main Outcomes and Measures: NICU admissions and special care days; inpatient mortality and 30-day postdischarge adverse events (ie, mortality, emergency department visit, admission, observation stay). Results: The overall cohort of 874 280 single LBs included 9938 VLBW (5054 [50.9%] female; mean [SD] birth weight, 1028.9 [289.6] g; mean [SD] gestational age, 27.6 [2.6] wk), 63 160 LPT (33 684 [53.3%] female; mean [SD] birth weight, 2664.0 [409.4] g; mean [SD] gestational age, 35.4 [0.8] wk), and 801 182 NPT (407 977 [50.9%] female; mean [SD] birth weight, 3318.7 [383.4] g; mean [SD] gestational age, 38.9 [1.0] wk) LBs. Median (IQR) NICU capacity was 0.84 (0.57-1.30) allocated beds/100 LB/year. For VLBW newborns, NICU capacity was not associated with the risk of NICU admission or number of special care days. For LPT newborns, birth in hospitals with the highest compared with the lowest category of capacity was associated with a 17% higher risk of NICU admission (adjusted risk ratio [aRR], 1.17; 95% CI, 1.01-1.33). For NPT newborns, risk of NICU admission was 55% higher (aRR, 1.55; 95% CI, 1.22-1.97) in the highest- vs the lowest-capacity hospitals. The number of special care days for LPT and NPT newborns was 21% (aRR, 1.21; 95% CI,1.08-1.36) and 37% (aRR, 1.37; 95% CI, 1.08-1.74) higher in the highest vs lowest capacity hospitals, respectively. Among LPT and NPT newborns, NICU capacity was associated with higher inpatient mortality and 30-day postdischarge adverse events. Conclusions and Relevance: In this cohort study of Medicaid-insured newborns in Texas, greater hospital NICU bed supply was associated with increased NICU utilization in newborns born LPT and NPT. Higher capacity was not associated with lower risk of adverse events. These findings raise important questions about how the NICU is used for newborns with lower risk.

Evaluation of negative binomial and zero-inflated negative binomial models for the analysis of zero-inflated count data: application to the telemedicine for children with medical complexity trial.

BACKGROUND: Two characteristics of commonly used outcomes in medical research are zero inflation and non-negative integers; examples include the number of hospital admissions or emergency department visits, where the majority of patients will have zero counts. Zero-inflated regression models were devised to analyze this type of data. However, the performance of zero-inflated regression models or the properties of data best suited for these analyses have not been thoroughly investigated. METHODS: We conducted a simulation study to evaluate the performance of two generalized linear models, negative binomial and zero-inflated negative binomial, for analyzing zero-inflated count data. Simulation scenarios assumed a randomized controlled trial design and varied the true underlying distribution, sample size, and rate of zero inflation. We compared the models in terms of bias, mean squared error, and coverage. Additionally, we used logistic regression to determine which data properties are most important for predicting the best-fitting model. RESULTS: We first found that, regardless of the rate of zero inflation, there was little difference between the conventional negative binomial and its zero-inflated counterpart in terms of bias of the marginal treatment group coefficient. Second, even when the outcome was simulated from a zero-inflated distribution, a negative binomial model was favored above its ZI counterpart in terms of the Akaike Information Criterion. Third, the mean and skewness of the non-zero part of the data were stronger predictors of model preference than the percentage of zero counts. These results were not affected by the sample size, which ranged from 60 to 800. CONCLUSIONS: We recommend that the rate of zero inflation and overdispersion in the outcome should not be the sole and main justification for choosing zero-inflated regression models. Investigators should also consider other data characteristics when choosing a model for count data. In addition, if the performance of the NB and ZINB regression models is reasonably comparable even with ZI outcomes, we advocate the use of the NB regression model due to its clear and straightforward interpretation of the results.

Costs associated with postoperative intra-abdominal abscess in pediatric perforated appendicitis: A retrospective cohort study.

BACKGROUND: Intra-abdominal abscess, the most common complication after perforated appendicitis, is associated with considerable economic burden. However, costs of intra-abdominal abscesses in children are unknown. We aimed to evaluate resource utilization and costs attributable to intra-abdominal abscess in pediatric perforated appendicitis. METHODS: A single-center retrospective analysis was performed of children (<18 years) who underwent appendectomy for perforated appendicitis (2013-2019). Hospital costs incurred during the index admission and within 30 postoperative days were obtained from the hospital accounting system and inflated to 2019 USD. Generalized linear models were used to determine excess resource utilization and costs attributable to intra-abdominal abscess after adjusting for confounders. RESULTS: Of 763 patients, 153 (20%) developed intra-abdominal abscesses. Eighty-one patients with intra-abdominal abscesses (53%) underwent percutaneous abscess drainage. Intra-abdominal abscess was independently associated with a nearly 8-fold increased risk of 30-day readmission (adjusted risk ratio, 7.8 [95% confidence interval, 4.7-13.0]). Patients who developed an intra-abdominal abscess required 6.1 excess hospital bed days compared to patients without intra-abdominal abscess (95% confidence interval, 5.3-7.0). Adjusted mean hospital costs for patients with intra-abdominal abscess totaled $27,394 (95% confidence interval, $25,688-$29,101) versus $15,586 (95% confidence interval, $15,102-$16,069) for patients without intra-abdominal abscess. Intra-abdominal abscess was associated with an incremental cost of $11,809 (95% confidence interval, $10,029-$13,588). Hospital room costs accounted for 66% of excess costs. CONCLUSION: Postoperative intra-abdominal abscess nearly doubled pediatric perforated appendicitis costs, primarily due to more hospital bed days and associated room costs. Intra-abdominal abscesses resulted in estimated excess costs of $1.8 million during the study period. Even small reductions in intra-abdominal abscess rates or hospital bed days could yield substantial health care savings.

Early discharge after nonoperative management of intussusception is both safe and cost-effective.

BACKGROUND/PURPOSE: We implemented a quality improvement (QI) initiative to safely reduce post-reduction monitoring for pediatric patients with ileocolic intussusception. We hypothesized that there would be decreased length of stay (LOS) and hospital costs, with no change in intussusception recurrence rates. METHODS: A retrospective cohort study was conducted of pediatric ileocolic intussusception patients who underwent successful enema reduction at a tertiary-care pediatric hospital from January 2015 through June 2020. In September 2017, an intussusception management protocol was implemented, which allowed discharge within four hours of reduction. Pre- and post-QI outcomes were compared for index encounters and any additional encounter beginning within 24 h of discharge. An economic evaluation was performed with hospital costs inflation-adjusted to 2020 United States Dollars ($). Cost differences between groups were assessed using multivariable regression, adjusting for Medicaid and transfer status, P < 0.05 significant. RESULTS: Of 90 patients, 37(41%) were pre-QI and 53(59%) were post-QI. Patients were similar by age, sex, race, insurance status, and transfer status. Pre-QI patients had a median LOS of 23.4 h (IQR: 16.1-34.6) versus 9.3 h (IQR 7.4-14.2) for post-QI patients, P < 0.001. Mean total costs per patient in the pre-QI group were $3,231 (95% CI, $2,442-$4,020) versus $1,861 (95% CI, $1,481-$2,240) in the post-QI group. The mean absolute cost difference was $1,370 less per patient in the post-QI group (95% CI, [-$2,251]-[-$490]). Five patients had an additional encounter within 24 h of discharge [pre-QI: 1 (3%) versus post-QI: 4 (8%), p = 0.7] with four having intussusception recurrence [pre-QI: 1 (3%) versus post-QI: 3 (6%), p = 0.6]. CONCLUSIONS: Implementation of a quality improvement initiative for the treatment of pediatric intussusception reduced hospital length of stay and costs without negatively affecting post-discharge encounters or recurrence rates. Similar protocols can easily be adopted at other institutions. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Retrospective comparative treatment study.

Hospital Consultation From Outpatient Clinicians for Medically Complex Children: A Randomized Clinical Trial.

Importance: Children with medical complexity (CMC) frequently experience fragmented care. We have demonstrated that outpatient comprehensive care (CC) reduces serious illnesses, hospitalizations, and costs for high-risk CMC. Yet continuity of care for CMC is often disrupted with emergency department (ED) visits and hospitalizations. Objective: To evaluate a hospital consultation (HC) service for CMC from their outpatient CC clinicians. Design, Setting, and Participants: Randomized quality improvement trial at the University of Texas Health Science Center at Houston with an outpatient CC clinic and tertiary pediatric hospital (Children's Memorial Hermann Hospital). Participants included high-risk CMC (≥2 hospitalizations or ≥1 pediatric intensive care unit [PICU] admission in the year before enrolling in our clinic) receiving CC. Data were analyzed between January 11, 2018, and December 20, 2019. Interventions: The HC included serial discussions between CC clinicians, ED physicians, and hospitalists addressing need for admission, inpatient treatment, and transition back to outpatient care. Usual hospital care (UHC) involved routine pediatric hospitalist care. Main Outcomes and Measures: Total hospital days (primary outcome), PICU days, hospitalizations, and health system costs in skeptical bayesian analyses (using a prior probability assuming no benefit). Results: From October 3, 2016, through October 2, 2017, 342 CMC were randomized to either HC (n = 167) or UHC (n = 175) before meeting the predefined bayesian stopping guideline (>80% probability of reduced hospital days). In intention-to-treat analyses, the probability that HC reduced total hospital days was 91% (2.72 vs 6.01 per child-year; bayesian rate ratio [RR], 0.61; 95% credible interval [CrI], 0.30-1.26). The probability of a reduction with HC vs UHC was 98% for hospitalizations (0.60 vs 0.93 per child-year; RR, 0.68; 95% CrI, 0.48-0.97), 89% for PICU days (0.77 vs 1.89 per child-year; RR, 0.59; 95% CrI, 0.26-1.38), and 94% for mean total health system costs ($24 928 vs $42 276 per child-year; cost ratio, 0.67; 95% CrI, 0.41-1.10). In secondary analysis using a bayesian prior centered at RR of 0.78, reflecting the opinion of 7 experts knowledgeable about CMC, the probability that HC reduced hospital days was 96%. Conclusions and Relevance: Among CMC receiving comprehensive outpatient care, an HC service from outpatient clinicians likely reduced total hospital days, hospitalizations, PICU days, other outcomes, and health system costs. Additional trials of an HC service from outpatient CC clinicians are needed for CMC in other centers. Trial Registration: ClinicalTrials.gov Identifier: NCT02870387.

Telemedicine for Children With Medical Complexity: A Randomized Clinical Trial.

BACKGROUND: Telemedicine is widely used but has uncertain value. We assessed telemedicine to further improve outcomes and reduce costs of comprehensive care (CC) for medically complex children. METHODS: We conducted a single-center randomized clinical trial comparing telemedicine with CC relative to CC alone for medically complex children in reducing care days outside the home (clinic, emergency department, or hospital; primary outcome), rate of children developing serious illnesses (causing death, ICU admission, or hospital stay >7 days), and health system costs. We used intent-to-treat Bayesian analyses with neutral prior assuming no benefit. All participants received CC, which included 24/7 phone access to primary care providers (PCPs), low patient-to-PCP ratio, and hospital consultation from PCPs. The telemedicine group also received remote audiovisual communication with the PCPs. RESULTS: Between August 22, 2018, and March 23, 2020, we randomly assigned 422 medically complex children (209 to CC with telemedicine and 213 to CC alone) before meeting predefined stopping rules. The probability of a reduction with CC with telemedicine versus CC alone was 99% for care days outside the home (12.94 vs 16.94 per child-year; Bayesian rate ratio, 0.80 [95% credible interval, 0.66-0.98]), 95% for rate of children with a serious illness (0.29 vs 0.62 per child-year; rate ratio, 0.68 [0.43-1.07]) and 91% for mean total health system costs (US$33 718 vs US$41 281 per child-year; Bayesian cost ratio, 0.85 [0.67-1.08]). CONCLUSION: The addition of telemedicine to CC likely reduced care days outside the home, serious illnesses, other adverse outcomes, and health care costs for medically complex children.

Cost-utility analysis of palonosetron-based therapy in preventing emesis among breast cancer patients.

We estimated the cost-utility of palonosetron-based therapy compared with generic ondansetron-based therapy throughout four cycles of anthracycline and cyclophosphamide for treating women with breast cancer. We developed a Markov model comparing six strategies in which ondansetron and palonosetron are combined with either dexamethasone alone, dexamethasone plus aprepitant following emesis, or dexamethasone plus aprepitant up front. Data on the effectiveness of antiemetics and emesis-related utility were obtained from published sources. Relative to the ondansetron-based two-drug therapy, the incremental cost-effectiveness ratios for the palonosetron-based regimens were $115,490/quality-adjusted life years (QALY) for the two-drug strategy, $199,375/QALY for the two-drug regimen plus aprepitant after emesis, and $200,526/QALY for the three-drug strategy. In sensitivity analysis, using the $100,000/QALY benchmark, the palonosetron-based two-drug strategy and the two-drug regimen plus aprepitant following emesis were shown to be cost-effective in 39% and 26% of the Monte Carlo simulations, respectively, and with changes in values for the effectiveness of antiemetics and the rate of hospitalization. The cost-utility of palonosetron-based therapy exceeds the $100,000/QALY threshold. Future research incorporating the price structure of all antiemetics following ondansetron's recent patent expiration is needed.

Whole blood transfusion versus component therapy in trauma resuscitation: a systematic review and meta-analysis.

BACKGROUND: Patients with hemorrhagic shock from trauma often require balanced blood product transfusion with red blood cells, plasma, and platelets. Resuscitation with whole blood resuscitation is becoming a common practice. We performed a systematic review and meta-analysis of studies comparing whole blood transfusion with balanced component therapy in patients suffering from traumatic hemorrhagic shock. METHODS: We searched MEDLINE Ovid, EMBASE, and the Cochrane Library for human studies comparing whole blood with component blood therapy published from January 2007 to June 2019. We included studies from both civilian and military settings and that reported 24-hour, in-hospital, or 30-day mortality. We followed the Preferred Reporting Items in Systematic Reviews and Meta-Analyses (PRISMA) guidelines, assessing study quality, publication bias, and heterogeneity. We used meta-analytic models to determine the associations (odds ratio [OR] with 95% confidence interval [CI]) between whole blood transfusion and (1) 24-hour mortality, and (2) in-hospital or 30-day mortality. RESULTS: A total of 1759 identified studies, 12 (reporting on n = 8431 patients) met inclusion criteria. There was heterogeneity in the design, setting, interventions, and outcomes of the studies. On meta-analysis, whole blood transfusion was not associated with 24-hour mortality (OR = 0.83; 95% CI = 0.56-1.24) or in-hospital/30-day mortality (OR = 0.79; 95% CI = 0.48-1.31). CONCLUSION: In this systematic review and meta-analysis, compared with conventional component transfusion, whole blood was not associated with 24-hour or in-hospital mortality. However, there were important limitations with and heterogeneity among the primary studies. Additional study is needed to determine the effectiveness of whole blood.

Hospitalizations for infection in cancer patients: impact of an aging population.

GOAL OF WORK: The aim of this study was to assess the impact of an aging US population on inpatient costs and resource utilization in cancer patients admitted for infection. MATERIALS AND METHODS: From the Texas inpatient public use files (Texas Health Care Information Collection), which include all hospitals except federal institutions, we selected residents with cancer who also had a principal or admitting diagnosis of pneumonia, bacteremia/sepsis, or other documented infection in 2001. Selected admission records were directly adjusted by projected age-specific cancer prevalence totals for years 2006 and 2025 using surveillance epidemiology end results (SEER) and US census data. Charges were inflated to 2006 consumer price index for medical care then converted to costs using Texas Medicare cost-to-charge ratios. RESULTS: Over 9% of nearly 200,000 Texans admitted for infection in 2001 also had cancer. Projecting these results nationally, 318,000 discharges in cancer patients at a cost of $3.1 billion (B, 95% CI $2.8B, $3.4B) and 2.3 million (M) bed days would have been attributed to infections in 2006. By the year 2025, adjusting only for the aging population, costs could increase 45% to $4.5B (95% CI $4.1B, $4.9), with 27% more (3.4 M) hospital bed days occupied. CONCLUSIONS: Consequent to an aging population and the resulting increase in cancer prevalence, the healthcare burden of managing hospital admissions for infection in the vulnerable cancer population could be greatly magnified unless risk-based treatment and preventive strategies such as appropriate immunizations and infection control measures are implemented.

Psychosocial and economic impact of cancer.

This article explores the psychosocial and economic implications of cancer and their relevance to the clinician. After a general overview of the topic, the authors focus on aspects of particular importance to the dental professional, including the psychosocial and economic implications of the oral complications of cancer and its therapy, head and neck cancers, and special issues among children with cancer and cancer survivors.

Outcomes and cost of deep venous thrombosis among patients with cancer.

BACKGROUND: Although deep venous thrombosis (DVT) often complicates the clinical course in patients with cancer, few studies of the outcomes of DVT in this population have been published. Furthermore, the cost of DVT is largely undescribed. We herein report the largest study of DVT in this population to date. METHODS: We reviewed the medical records of 529 consecutive cancer patients in whom DVT developed from January 1, 1994, through December 31, 1997, and followed up these patients through December 31, 2000, for outcomes. The cost of hospitalization was obtained from our hospital's cost-accounting system and inflated to 2002 US dollars using the Consumer Price Index for Medical Care. Logistic regression was used to identify factors that were associated with a high risk of poor outcomes. RESULTS: The most common complication of DVT was bleeding, which occurred in 13% of patients. Pulmonary embolus occurred in 4%. Five patients (1%) died of complications of DVT and 5 (1%) of complications of anticoagulation. Recurrence of DVT was common (17% overall), particularly among those who had inferior vena cava filters (32%; P<.001) or a previous episode of DVT (P =.03). All but 4 patients were hospitalized for initial anticoagulation therapy, for a mean of 11 days. The mean cost of hospitalization was 2002 US $20 065. CONCLUSIONS: Among patients with cancer, DVT frequently is associated with serious clinical outcomes. Its treatment is resource intensive and costly. More effective agents and less costly management strategies could have a significant impact on the outcomes and cost of DVT in this population.

Scope and epidemiology of cancer therapy-induced oral and gastrointestinal mucositis.

OBJECTIVE: To discuss the scope and epidemiology of cancer therapy-induced mucositis. DATA SOURCE: Peer-reviewed articles and book chapters. CONCLUSION: Mucositis is a frequent and costly complication of cancer treatment. The risk of cancer therapy-induced mucositis varies depending on a number of patient- and treatment-related factors. IMPLICATIONS FOR NURSING PRACTICE: An awareness of the risk factors associated with mucositis will allow nurses to identify cancer patients at greatest risk and incorporate supportive care measures into their management plans.

Mammography capacity impact on screening rates and breast cancer stage at diagnosis.

BACKGROUND: Mammography capacity in the U.S. reportedly is adequate, but has not been examined in nonmetropolitan areas. This study examined the relationships between in-county mammography facilities and rates of mammography screening and late-stage diagnosis of breast cancers. METHODS: The association between a mammography facility in the county of residence (2002-2004) and the odds of screening within 2 years were examined (in 2007) among Texas women aged >40 years who responded to the 2004 Behavioral Risk Factor Surveillance System survey, using multivariate logistic regression to control for age, race, ethnicity, education, income, self-reported health, insurance, and usual source of care. Similarly, the association between an in-county mammography facility and the odds of diagnosis with locally advanced or disseminated disease was examined among Texas women aged >40 years who developed breast cancer in 2004. RESULTS: Half of the 254 counties in Texas had no mammography facility. After controlling for confounding factors, an in-county facility was associated with significantly higher odds of screening (OR=3.27; p=0.03) and lower odds of late-stage breast cancer at diagnosis (OR=0.36; 95% CI=0.26-0.51; p<0.001). The risks of late-stage diagnosis were higher for African-American women (OR=1.52; 95% CI=1.22-1.89; p<0.001) and Hispanic women (OR=1.23; 95% CI=0.99-1.53; p=0.06) than for white women. CONCLUSIONS: Although mammography capacity in the U.S. may be adequate on average, the unequal distribution of facilities results in large rural areas without facilities. Screening rates in these areas are suboptimal and are associated with late-stage diagnosis of breast cancer.
