Clinical Performance Measures for Emergency Department Care for Adults With Intracranial Hemorrhage.

Though select inpatient-based performance measures exist for the care of patients with nontraumatic intracranial hemorrhage, emergency departments lack measurement instruments designed to support and improve care processes in the hyperacute phase. To address this, we propose a set of measures applying a syndromic (rather than diagnosis-based) approach informed by performance data from a national sample of community EDs participating in the Emergency Quality Network Stroke Initiative. To develop the measure set, we convened a workgroup of experts in acute neurologic emergencies. The group considered the appropriate use case for each proposed measure: internal quality improvement, benchmarking, or accountability, and examined data from Emergency Quality Network Stroke Initiative-participating EDs to consider the validity and feasibility of proposed measures for quality measurement and improvement applications. The initially conceived set included 14 measure concepts, of which 7 were selected for inclusion in the measure set after a review of data and further deliberation. Proposed measures include 2 for quality improvement, benchmarking, and accountability (Last 2 Recorded Systolic Blood Pressure Measurements Under 150 and Platelet Avoidance), 3 for quality improvement and benchmarking (Proportion of Patients on Oral Anticoagulants Receiving Hemostatic Medications, Median ED Length of Stay for admitted patients, and Median Length of Stay for transferred patients), and 2 for quality improvement only (Severity Assessment in the ED and Computed Tomography Angiography Performance). The proposed measure set warrants further development and validation to support broader implementation and advance national health care quality goals. Ultimately, applying these measures may help identify opportunities for improvement and focus quality improvement resources on evidence-based targets.

Burden of influenza in patients with cardiovascular disease who receive antiviral treatment for influenza.

AIMS: Cardiovascular disease (CVD) increases the risk of complications from respiratory viruses, including influenza. Moreover, respiratory viruses may increase the risk of CV events. Antiviral medication may reduce healthcare resource utilization (HRU), but more data is needed in CVD populations to explore relationships between influenza antiviral treatment, CVD-related complications, HRU, and costs. MATERIALS AND METHODS: This retrospective claims analysis examined data extracted from IBM MarketScan Commercial Claims and Encounters and Medicare Supplemental and Coordination of Benefits databases during three influenza seasons: 2016-2017, 2017-2018, or 2018-2019. Propensity score matching was used to compare HRU outcomes and costs among CVD patients treated with influenza antivirals and untreated patients. RESULTS: Across all influenza seasons, patients with CVD and influenza who received antiviral treatment had fewer all-cause emergency department (ED) visits (p < .01), respiratory-related HRU (p < .01), respiratory-related outpatient and ED visits (both p < .01), CVD-related HRU (p < .01), heart failure-related HRU visits (p < .01), and kidney failure-related HRU (p < .01) 180 days post-treatment fill date than CVD patients untreated for influenza. CVD patients treated with antivirals also had a lower mean number of all-cause inpatient, outpatient, and ED visits and days of stay (all p < .01) and fewer mean respiratory-related outpatient and ED visits (both p < .01). HRU patterns were generally consistent over time and across individual influenza seasons. Finally, treated CVD patients incurred lower all-cause outpatient costs 180 days post-treatment fill date (p < .05) than CVD patients untreated for influenza. CONCLUSION: CVD patients who contract influenza and take antiviral medication have fewer short- and long-term influenza-related complications and less overall HRU compared with CVD patients who were not prescribed antiviral treatments. Antiviral treatment may be an important tool in reducing complications in CVD patients with influenza.

People with heart disease are more likely to have complications from respiratory viruses, including influenza (flu). Moreover, respiratory viruses may increase the risk of damage to the heart muscle. We examined whether patients with heart disease who get the flu and take prescription medications called antiviral drugs have fewer short- and long-term flu-related complications and use fewer healthcare services than patients with heart disease who do not take antiviral drugs.We examined commercial and Medicare databases during three influenza seasons (2016­2017, 2017­2018, and 2018­2019), and we compared outcomes and costs among heart disease patients who were treated or not treated with antiviral drugs. Patients with heart disease and the flu who received antiviral drugs had fewer visits to the emergency room, used fewer healthcare services for respiratory-related problems, used fewer heart disease-related healthcare services, and had fewer heart failure-related or kidney failure-related healthcare visits than heart disease patients who were not treated for the flu. Finally, patients with heart disease who were treated with antiviral drugs spent less money on outpatient services than patients with heart disease who were not treated with antiviral drugs.We determined that patients who get the flu and take antiviral drugs have fewer short- and long-term flu-related complications and use fewer healthcare services than heart disease patients who do not receive antiviral drugs. Therefore, it may be important to treat heart disease patients with antiviral drugs in order to reduce the number of flu-related complications in these patients.

Antifibrotic therapies reduce mortality and hospitalization among Medicare beneficiaries with idiopathic pulmonary fibrosis.

BACKGROUND: Additional real-world studies are needed to more fully elucidate the effectiveness of antifibrotic treatment in slowing the progression of idiopathic pulmonary fibrosis (IPF). OBJECTIVE: To compare mortality and hospitalization between Medicare beneficiaries with IPF who initiate antifibrotic therapy and those who did not receive treatment. METHODS: A retrospective observational study of Medicare beneficiaries using the 100% Medicare Research Identifiable File was conducted. We included patients aged 67 years and over diagnosed with IPF (≥ 1 inpatient or ≥ 2 outpatient claims with IPF diagnosis) during the study period (January 1, 2010-December 31, 2017). Patients who initiated antifibrotic treatment (pirfenidone or nintedanib) between October 15, 2014 (FDA approval date) and December 31, 2017 (ie, treated patients) were compared with those who did not receive treatment during a historical period (January 1, 2012-October 14, 2014) before the availability of antifibrotics (ie, untreated historical controls). Patients were matched by propensity score, and the outcomes, mortality, and hospitalization (all cause and respiratory related) were compared using a Cox proportional hazards model. RESULTS: We identified 4,641 treated patients and 4,641 propensity score-matched controls who met all study criteria; 352 treated patients who lacked matches were excluded from the study. Cox regression analysis of treated patients vs matched controls showed a significantly lower risk of mortality (HR = 0.62, 95% CI = 0.57-0.68); lower risk of hospitalization (HR = 0.71, 95% CI = 0.67-0.76; HR = 0.70, 95% CI = 0.64-0.76); and lower rate in number of hospitalizations per month (incident rate ratio [IRR] = 0.65, 95% CI = 0.60-0.71; IRR = 0.65, 95% CI = 0.58-0.73). CONCLUSIONS: This study suggests that treatment with antifibrotics may confer a survival benefit and protection against all-cause and respiratory-related hospitalization for IPF patients.

Healthcare use and costs among Medicare enrollees on pirfenidone versus nintedanib for idiopathic pulmonary fibrosis.

Aim: Compare healthcare utilization and costs between Medicare beneficiaries with idiopathic pulmonary fibrosis (IPF) receiving pirfenidone or nintedanib. Methods: Retrospective cohort study of Medicare beneficiaries (100% Research Identifiable Files) with IPF who initiated pirfenidone or nintedanib between 15 October 2014 and 31 December 2015. Inverse probability of treatment weighting using propensity scores adjusted for baseline covariates. Outcomes: hospitalization and monthly costs. Results: Hazard and incidence rate ratios (95% CI) for all-cause (0.79 [0.68-0.91]; 0.69 [0.59-0.82]) and respiratory-related (0.80 [0.65-0.97]; 0.71 [0.57-0.90]) hospitalizations favored pirfenidone versus nintedanib. Monthly inpatient costs were lower for pirfenidone versus nintedanib patients; outpatient and pharmacy costs were similar. Conclusion: In patients with IPF, pirfenidone compared with nintedanib has a moderate but significant protective effect on hospitalization, corresponding to lower inpatient costs.

Treatment patterns, healthcare resource utilization, and costs among patients with idiopathic pulmonary fibrosis treated with antifibrotic medications in US-based commercial and Medicare Supplemental claims databases: a retrospective cohort study.

BACKGROUND: Pirfenidone and nintedanib are antifibrotic therapies which slow disease progression in idiopathic pulmonary fibrosis (IPF), an irreversible, progressive lung disease with poor prognosis. We compared adherence, persistence, and healthcare costs between patients initiating one of the two therapies. METHODS: We used the IBM Watson Health Commercial and Medicare Supplemental claims databases to select patients with IPF with ≥1 pharmacy claim for pirfenidone or nintedanib between 10/1/2014 and 6/30/2018. Adherence (proportion of days covered ≥0.80) and persistence (time to a gap of ≥60 days without medication or switch to the other antifibrotic medication) based on the days' supply and service date fields on claims were measured over a variable-length follow-up period. Healthcare costs, all-cause and respiratory-related, were measured over the persistent period and a fixed 12-month follow-up period. Inverse probability of treatment weights were applied to models comparing adherence, persistence, and costs between the two cohorts. RESULTS: Overall, 799 pirfenidone patients and 656 nintedanib patients were identified. Similar proportions of patients were adherent in both cohorts (pirfenidone = 49% vs. nintedanib = 51%) and there was no significant difference in the odds of being adherent after weighting (odds ratio = 1.1, p = 0.513). The proportions of patients who discontinued/switched were also similar (pirfenidone = 41% vs. nintedanib 43%); however, in a weighted model, the hazards of discontinuation/switching was lower for the pirfenidone cohort (hazard ratio = 0.8, p = 0.032). While patients were persistent on therapy, weighted all-cause healthcare costs were comparable (pirfenidone = $11,272 vs. nintedanib = $11,987 per-patient per-month; p = 0.115), but weighted respiratory-related costs were significantly lower for the pirfenidone cohort ($9015 vs. $10,167 per-patient per-month, p < 0.001). Weighted annual total all-cause and respiratory-related healthcare costs were comparable between cohorts over the fixed 12-month follow-up period, but the pirfenidone cohort had significantly lower weighted annual mean antifibrotic drug costs than the nintedanib cohort ($68,850 vs. $77,033, p = 0.007). CONCLUSIONS: Pirfenidone use was associated with longer time to discontinuation/switch, lower antifibrotic drug costs, and lower respiratory-related total costs compared to nintedanib use.

Length of stay and hospitalization costs for patients undergoing lung surgery with Progel pleural air leak sealant.

AIM: Progel Pleural Air Leak Sealant (Progel) is currently the only sealant approved by the FDA for the treatment of air leaks during lung surgery. This study was performed to determine whether Progel use improves hospital length of stay (LOS) and hospitalization costs compared with other synthetic/fibrin sealants in patients undergoing lung surgery. METHODS: The US Premier hospital database was used to identify lung surgery discharges from January 1, 2010 to June 30, 2015. Eligible discharges were categorized as "Progel Sealant" or "other sealants" using hospital billing data. Propensity score matching (PSM) was performed to control for hospital and patient differences between study groups. Primary outcomes were hospital LOS and all-cause hospitalization costs. Clinical outcomes, hospital re-admissions, and sealant product use were also described. RESULTS: After PSM, a total of 2,670 discharges were included in each study group; baseline characteristics were balanced between groups. The hospital LOS (mean days ± standard deviation, median) was significantly shorter for the Progel group (9.9 ± 9.6, 7.0) compared with the other sealants group (11.3 ± 12.8, 8.0; p < .001). Patients receiving Progel incurred significantly lower all-cause hospitalization costs ($31,954 ± $29,696, $23,904) compared with patients receiving other sealants ($36,147 ± $42,888, $24,702; p < .001). LIMITATIONS: It is not possible to say that sealant type alone was responsible for the findings of this study, and analysis was restricted to the data available in the Premier database. CONCLUSIONS: Among hospital discharges for lung surgery, Progel use was associated with significantly shorter hospital LOS and lower hospitalization costs compared with other synthetic/fibrin sealants, without compromising clinical outcomes.

A hospital cost analysis of a fibrin sealant patch in soft tissue and hepatic surgical bleeding.

BACKGROUND: Despite hemostat use, uncontrolled surgical bleeding is prevalent. Drawbacks of current hemostats include limitations with efficacy on first attempt and suboptimal ease-of-use. Evarrest® is a novel fibrin sealant patch that has demonstrated high hemostatic efficacy compared with standard of care across bleeding severities. The objective of this study was to conduct a hospital cost analysis of the fibrin sealant patch versus standard of care in soft tissue and hepatic surgical bleeding. METHODS: The analysis quantified the 30-day costs of each comparator from a hospital perspective. Published US unit costs were applied to resource use (ie, initial treatment, retreatment, operating time, hospitalization, transfusion, and ventilator) reported in four trials. A "surgical" analysis included resources clinically related to the hemostatic benefit of the fibrin sealant patch, whereas a "hospital" analysis included all resources reported in the trials. An exploratory subgroup analysis focused solely on coagulopathic patients defined by abnormal blood test results. RESULTS: The surgical analysis predicted cost savings of $54 per patient with the fibrin sealant patch compared with standard of care (net cost impact: -$54 per patient; sensitivity range: -$1,320 to $1,213). The hospital analysis predicted further cost savings with the fibrin sealant patch (net cost impact of -$2,846 per patient; sensitivity range: -$1,483 to -$5,575). Subgroup analyses suggest that the fibrin sealant patch may provide dramatic cost savings in the coagulopathic subgroup of $3,233 (surgical) and $9,287 (hospital) per patient. Results were most sensitive to operating time and product units. CONCLUSION: In soft tissue and hepatic problematic surgical bleeding, the fibrin sealant patch may result in important hospital cost savings.

Variation in hospital resource use and cost among surgical procedures using topical absorbable hemostats.

BACKGROUND: Adjunctive hemostats are used to assist with the control of intraoperative bleeding. The most common types are flowables, gelatins, thrombins, and oxidized regenerated celluloses (ORCs). In the US, Surgicel(®) products are the only US Food and Drug Administration-approved ORCs. OBJECTIVE: To compare the outcomes of health care resource utilization (HRU) and costs associated with using ORCs compared to other adjunctive hemostats (OAHs are defined as flowables, gelatins, and topical thrombins) for surgical procedures in the US inpatient setting. PATIENTS AND METHODS: A retrospective, US-based cohort study was conducted using hospital inpatient discharges from the 2011-2012 calendar years in the Premier Healthcare Database. Patients with either an ORC or an OAH who underwent a cardiovascular procedure (valve surgery and/or coronary artery bypass graft surgery), carotid endarterectomy, cholecystectomy, or hysterectomy were included. Propensity score matching was used to create comparable groups of ORC and OAH patients. Clinical, economic, and HRU outcomes were compared. RESULTS: The propensity score matching created balanced patient cohorts for cardiovascular procedure (22,718 patients), carotid endarterectomy (10,890 patients), cholecystectomy (6,090 patients), and hysterectomy (9,348 patients). In all procedures, hemostatic agent costs were 28%-56% lower for ORCs, and mean hemostat units per discharge were 16%-41% lower for ORCs compared to OAHs. Length of stay and total procedure costs for patients treated with ORCs were lower for carotid endarterectomy patients (0.3 days and US$700) and for cholecystectomy patients (1 day and US$3,350) (all P<0.001). CONCLUSION: Costs and HRU for patients treated with ORCs were lower than or similar to patients treated with OAHs. Proper selection of the appropriate hemostatic agents has the potential to influence clinical outcomes and treatment costs.

Health and economic outcomes associated with uncontrolled surgical bleeding: a retrospective analysis of the Premier Perspectives Database.

BACKGROUND: Bleeding remains a common occurrence in surgery. Data describing the burden of difficult-to-control bleeding and topical absorbable hemostat use are sparse. This study was conducted to estimate the clinical and economic impact that remains associated with uncontrolled surgical bleeding, even when hemostats are used during surgery. METHODS: This US retrospective analysis used the Premier Perspectives Database. Hospital discharges from 2012 were used to identify patients treated with hemostats during eight surgery types. Patients were included if they were ≥18 years, had an inpatient hospitalization with one of the eight surgeries, and received a hemostat on the day of surgery. Patients were stratified by procedure and presence or absence of major bleeding (uncontrolled) despite hemostat use. Outcomes were all-cause hospitalization costs, hemostat costs, length of stay, reoperation, and surgery-related complications (eg, mortality). Statistical significance was tested through chi-square or t-tests. Multivariate analyses were conducted for all-cause costs and length of stay using analysis of covariance. RESULTS: Among 25,048 procedures, major bleeding events occurred in 14,251 cases. Despite treatment with hemostats, major bleeding occurred in 32%-68% of cases. All-cause costs were significantly higher in patients with uncontrolled bleeding despite hemostat use versus controlled bleeding (US$24,203-$61,323 [uncontrolled], US$14,420-$45,593 [controlled]; P<0.001). Hemostat costs were significantly greater in the uncontrolled bleeding cohort for all surgery types except cystectomy and pancreatic surgery. Reoperation and mortality rates were significantly higher in the uncontrolled bleeding cohort in all surgical procedures except cystectomy and radical hysterectomy. CONCLUSION: Uncontrolled intraoperative bleeding despite hemostat use is prevalent and associated with significantly higher hospital costs and worse clinical outcomes across several surgical procedures compared to controlled bleeding. There is an unmet need for newer hemostats that can more effectively control bleeding, improve outcomes, and reduce hospital resource use.

Reduction in hospital costs and resource consumption associated with the use of advanced topical hemostats during inpatient procedures.

OBJECTIVE: The use of hemostatic agents has increased over time for all surgical procedures. The purpose of this study was to evaluate the newer topical absorbable hemostat products Surgicel * Fibrillar † and Surgicel SNoW ‡ (Surgicel advanced products, abbreviated as SAPs) compared to the older product Surgicel Original (SO) with respect to healthcare resource use and costs in procedures where these hemostats are most commonly used. RESEARCH DESIGN AND METHODS: A retrospective analysis of the Premier hospital database was used to identify adults who underwent brain/cerebral (BC), cardiovascular (CV: valve surgery and coronary artery bypass graft) and carotid endarterectomy (CEA) between January 2011-December 2012. Among these patients, those treated with SAPs were compared to those treated with SO. Propensity score matching (PSM) was used to create comparable groups to evaluate differences between SAPs and SO. MAIN OUTCOME MEASURES: The primary end-points for this study were length of stay (LOS), all-cause total cost, number of intensive care unit (ICU) days, ICU cost, transfusion costs and units, and SO/SAP product units per discharge. RESULTS: Matched PSM created patient cohorts for SO and SAPs were created for BC (n = 758 for both groups), CV (n = 3388 for both groups), and CEA (n = 2041 for both groups) procedures. Patients that received SAPs had a 14-16% lower mean LOS for each procedure compared to SO, as well as 12-18% lower total mean cost per discharge for each procedure (p < 0.02 for all results). Mean ICU costs for SAPs were also lower, with a reduction of 20% for BC and 19% for CV compared to SO (p < 0.01). However, for CEA, there was no statistically significant difference in ICU costs for SAPs compared to SO. CONCLUSIONS: In a retrospective hospital database analysis, the use of SAPs were associated with lower healthcare resource utilization and costs compared to SO.

An analysis of whether higher health care spending in the United States versus Europe is 'worth it' in the case of cancer.

The United States spends more on health care than other developed countries, but some argue that US patients do not derive sufficient benefit from this extra spending. We studied whether higher US cancer care costs, compared with those of ten European countries, were "worth it" by looking at the survival differences for cancer patients in these countries compared to the relative costs of cancer care. We found that US cancer patients experienced greater survival gains than their European counterparts; even after considering higher US costs, this investment generated $598 billion of additional value for US patients who were diagnosed with cancer between 1983 and 1999. The value of that additional survival gain was highest for prostate cancer patients ($627 billion) and breast cancer patients ($173 billion). These findings do not appear to have been driven solely by earlier diagnosis. Our study suggests that the higher-cost US system of cancer care delivery may be worth it, although further research is required to determine what specific tools or treatments are driving improved cancer survival in the United States.

Indirect comparison of the efficacy of cetuximab and cisplatin in squamous cell carcinoma of the head and neck.

BACKGROUND: Cetuximab (Erbitux*) is the only new medical therapy for locally and regionally advanced SCCHN to be licensed in industrialized countries in the past 15 years and presents an alternative to cisplatin which is the current therapeutic standard. In the absence of a published head-to-head trial, we estimated the relative benefit of cetuximab and cisplatin using an indirect comparison methodology. METHODS: We performed a systematic review of the Medline and Embase databases between 1998 and 2008 to find published trials of cisplatin plus radiotherapy vs. radiotherapy alone and synthesized the information with meta-analysis. Those results were combined with trial-based results of cetuximab plus radiotherapy vs. radiotherapy alone. Inclusion criteria stipulated that cisplatin be administered concurrently with radiation, the radiation protocol be comparable to the registration trial for cisplatin (once-daily, twice-daily, or concomitant boost) and cisplatin dosing be comparable to that in common use (i.e. day 1, 22 and 43 of treatment). Endpoints were locoregional control and overall survival. Two reviewers examined 269 abstracts which yielded four trials meeting the inclusion criteria. RESULTS: There was little evidence of superiority of either platinum-based radiotherapy or cetuximab-based radiotherapy. All estimated hazard ratios were near 1.0 (equivalence), all confidence intervals spanned the null value (1.0), and no consistent pattern was observed regarding the direction of the effect. The results remained robust in sensitivity analysis. CONCLUSION: This is the first quantitative analysis allowing formal comparison between cetuximab and radiotherapy versus cisplatin and radiotherapy. Based on state-of-the-art methodology for indirect comparisons, it was not possible to identify either treatment regimen as superior in prolonging either locoregional control or overall survival. Until the publication of more studies, and particularly a head-to-head comparison, the two treatments may be considered equally efficacious when given alongside radiotherapy. The choice of treatment may focus on the toxicity profile of the medications.

Pharmacoeconomic considerations in treating iron overload in patients with ß-thalassaemia, sickle cell disease and myelodysplastic syndromes in the US: a literature review.

Patients with ß-thalassaemia, sickle cell disease (SCD) and myelodysplastic syndromes (MDS) require chronic blood transfusions, which can lead to iron overload and substantial morbidity and mortality. To reduce the excess iron and its deleterious effects, available iron chelation therapy (ICT) in the US includes oral deferasirox or infusional deferoxamine (DFO). The aim of this study was to review and synthesize the available pharmacoeconomic evidence on ICT in patients with ß-thalassaemia, SCD and MDS in the US. We systematically identified and reviewed pharmacoeconomic studies of ICT in patients with ß-thalassaemia, SCD and MDS that either were published in MEDLINE-indexed, English-language journals from 1999 to 2009, or appeared in medical society websites and scientific meeting abstracts. We assessed available cost-of-illness, cost-of-treatment, cost-consequence, cost-effectiveness, utility and patient-satisfaction studies. The majority of the 20 identified studies assessed cost of treatment, mainly focusing on acquisition and administration costs of ICTs. Gaps in the published literature include current data on direct medical costs for patients with MDS, direct medical costs associated with complications of iron overload, direct non-medical costs, indirect costs and patient utilities. Different underlying model assumptions, methodologies and comparators were found in the cost-effectiveness studies, which yielded a broad range of incremental cost-effectiveness ratios for different ICTs. Comprehensive cost-of-illness studies are needed to address data gaps in the published literature regarding the economic burden of iron overload. Comparative-effectiveness studies that evaluate clinical, economic and patient-reported outcomes would help the medical community to better understand the value of different ICTs.

Incidence and clinical complications of myelodysplastic syndromes among United States Medicare beneficiaries.

PURPOSE: To determine the incidence and complications of myelodysplastic syndromes (MDS) among Medicare beneficiaries. METHODS: Retrospective review of 2003 Medicare Standard Analytic Files utilizing International Classification of Diseases for Oncology ninth edition CM code 238.7 to identify new MDS patients, with 3-year follow-up. RESULTS: Among 1,394,343 individuals in Medicare Standard Analytic Files age > or = 65 years, 162 per 100,000 were coded as newly diagnosed MDS during 2003 yielding a calculated 45,000 new cases in the United States Medicare > or = 65 years population. Patients with MDS were older (median age, 77 years), and over-represented by males. Among patients with MDS diagnosed during first quarter of 2003, 73.2% suffered cardiac-related events during 3-year follow-up, which exceeded the Medicare population (54.5%; P < .01) even when age adjusted (odds ratio, 2.10; P < .01). Significant increases in prevalence of diabetes (40.0% v 33.1%), dyspnea (49.4% v 28.5%), hepatic diseases (0.8% v 0.2%), and infections (sepsis: 22.5% v 6.1%) were noted in MDS (all P < .01) compared with the Medicare population. Patients with MDS requiring RBC transfusions had greater prevalence of these comorbidities. Acute myeloid leukemia developed within 3 years in 9.6%, with increased transformation among transfused (24.6%; P < .001). The 3-year Kaplan-Meier age-adjusted survival for MDS was 60.0%, which was significantly lower than the Medicare population (84.7%; hazard ratio, 3.08; P < .001), and mortality was further increased among transfused MDS (P < .01). In 2003, median payment for MDS was $16,181, compared to $1,575 for the Medicare population (P < .001). CONCLUSION: MDS is a common hematologic malignancy of the elderly, which places patients at risk for comorbid conditions. Transfusion dependency identifies patients with MDS at additional increased risk of organ impairment and shortened survival.

Treatment of transfusional iron overload in patients with myelodysplastic syndrome or severe anemia: data from multicenter clinical practices.

BACKGROUND: Patients with myelodysplastic syndrome (MDS) or severe anemia requiring repeated red blood cell (RBC) transfusions risk developing transfusional iron overload, which can reduce survival. Iron chelation therapy (ICT) has been shown to improve survival and quality of life in patients; however, ICT utilization in clinical practices is not well understood. STUDY DESIGN AND METHODS: Medical records of patients diagnosed with MDS or severe anemia at least 6 months before data extraction, aged at least 21 years at diagnosis, and who received at least one RBC transfusion were reviewed. ICT eligibility was defined as at least 20 units of RBCs transfused or at least two serum ferritin levels exceeding 1000 microg/L. Study endpoint was ICT treatment rate among ICT-eligible patients with lower-risk MDS (International Prognostic Scoring System [low or intermediate-1]; World Health Organization [refractory anemia {RA}, refractory anemia with ringed sideroblasts {RARS}, refractory cytopenia with multilineage dysplasia {RCMD}, refractory cytopenia with multilineage dysplasia and ringed sideroblasts, or 5q]; French-American-British [RA/RARS]). RESULTS: Among 78 ICT-eligible patients with lower-risk MDS, 32 (41%) received ICT. At ICT initiation, treated patients received on average 13.3 transfusions (27.6 units) and mean first post-ICT initiation serum ferritin was twice the MDS Foundation recommendation at 1949 microg/L. Median overall survival for all ICT-eligible patients was significantly longer for those ICT-treated patients than untreated patients (8.7 years vs. 4.7 years, log-rank p = 0.02; multivariate hazard ratio 0.372, p = 0.03). CONCLUSION: This study finds only 41% of ICT-eligible patients with lower-risk MDS received ICT in clinical practice, and treatment was initiated later than recommended. Receipt of ICT was associated with significantly longer survival.

Direct all-cause health care costs associated with chronic kidney disease in patients with diabetes and hypertension: a managed care perspective.

BACKGROUND: Diabetes and hypertension are the 2 major causes of endstage renal disease. The rate of chronic kidney disease (CKD) secondary to diabetes and/or hypertension is on the rise, and the related health care costs represent a significant economic burden. OBJECTIVE: To quantify from a health system perspective the incremental direct all-cause health care costs associated with a diagnosis of CKD in patients with diabetes and/or hypertension. METHODS: An analysis was conducted of medical claims and laboratory data with dates of service between January 1, 2000, and February 28, 2006, from a managed care database for approximately 30 million members enrolled in 35 health plans. Each patient's observation period began on the date of the first diabetes or hypertension diagnosis (index date) and ended on the earlier of the health plan disenrollment date or February 28, 2006. Inclusion criteria were continuous insurance coverage in the 6 months prior to the index date and during the observation period, age at least 18 years, and at least 2 claims less than 90 days apart with a primary or secondary diagnosis for diabetes or hypertension. Exclusion criteria were cancer, lupus, or organ transplantation or chemotherapy at any time during the observation period. CKD was defined as at least 1 claim with a primary or secondary diagnosis for CKD and at least 2 glomerular filtration rate values of below 60 milliliters per minute per 1.73 square meters of body surface area (60 mL/min/1.73 m(2)) at any time during the observation period. Bivariate and Tobit regression analyses were conducted to compare patients who developed CKD versus those who did not for annualized (per patient per month [PPPM] multiplied by 12) direct, all-cause, health care costs, defined as standardized net provider payments after subtraction of member cost-share. These costs consisted of outpatient services, inpatient services, and pharmacy claims. A subset analysis of the post-versus pre- CKD medical costs was also conducted for cohorts of patients with at least 60 days of observation before and after the development of CKD; that analysis measured both all-cause costs and costs for services directly related to CKD treatment (i.e., claims with a primary or secondary diagnosis of CKD or claims for dialysis services). RESULTS: 11,531 patients with diabetes, 74,759 patients with hypertension, and 4,779 patients with both conditions were identified, of whom 123 (1.1%), 1,137 (1.5%), and 712 (14.9%), respectively, developed CKD during the observation period. The CKD group was older than the no-CKD group in each cohort (mean ages for CKD vs. no-CKD were, respectively, diabetes only cohort: 60.7 vs. 49.9 years, P < 0.001; hypertension only cohort: 63.6 vs. 53.6 years, P < 0.001; diabetes and hypertension cohort: 63.4 vs. 61.8 years, P < 0.001). CKD was associated with significantly higher total direct all-cause health care costs, with unadjusted annualized per patient mean [median] cost differences of $11,814 [$6,895], $8,412 [$4,115], and $10,625 [$7,203], respectively (diabetes: $18,444 [$11,025] vs. $6,631 [$4,131], P < 0.001; hypertension: $14,638 [$7,817] vs. $6,226 [$3,703], P < 0.001; diabetes and hypertension: $21,452 [$13,840] vs. $10,827 [$6,637], P < 0.001). The largest driver of the all-cause mean cost difference associated with CKD for each cohort was hospitalization cost (diabetes: $6,410, P < 0.001; hypertension: $5,498, P < 0.001; diabetes and hypertension: $6,467, P < 0.001). Among patients developing CKD, all-cause mean [median] annualized costs increased significantly following CKD onset (increases for patients with diabetes: $8,829 [$4,899], P = 0.026; hypertension: $4,175 [$2,741], P = 0.004; diabetes and hypertension: $9,397 [$7,240], P < 0.001). In the post-CKD period, costs directly related to treatment of CKD accounted for 9%--19% of all-cause medical service costs--9.2% for patients with diabetes, 11.6% for patients with hypertension, and 18.8% for patients with both diabetes and hypertension. CONCLUSION: CKD was associated with significantly higher all-cause health care costs in managed care patients with diabetes and/or hypertension.
