Direct and indirect costs for patients with myeloproliferative neoplasms.

Myeloproliferative neoplasms (MPNs) are associated with substantial healthcare resource use and productivity loss. This retrospective cohort analysis used disability leave and medical claims data to measure direct and indirect healthcare costs associated with MPNs. The analysis included 173 patients with myelofibrosis (MF), 4477 with polycythemia vera (PV), 6061 with essential thrombocythemia (ET), and matched controls (n = 519, n = 13,431, and n = 18,183, respectively). Total healthcare costs were significantly higher for cases versus controls in each cohort (mean cost difference: MF, $67,456; PV, $10,970; ET, $22,279). Cases were more likely than controls to take disability leave and incurred higher disability-related costs. Among subgroups with thrombotic events, direct and indirect costs were higher for cases versus controls. Thrombotic events substantially increased direct costs and disability leave for patients with PV or ET compared with the full PV or ET cohorts. These findings demonstrate increased economic burden for patients with MPNs.

Ruxolitinib for myelofibrosis in elderly non-transplant patients: healthcare resource utilization and costs.

AIM: This study evaluated real-world healthcare resource utilization (HCRU), direct costs, and overall survival (OS) of patients who were Medicare beneficiaries and were newly diagnosed with myelofibrosis (MF) who filled ≥1 prescription of ruxolitinib versus those who did not. PATIENTS AND METHODS: This was a study of the US Medicare fee-for-service database. Beneficiaries were aged ≥65 years with an MF diagnosis (index) between January 1, 2012 - December 31, 2017. Data were summarized descriptively. OS was estimated using Kaplan-Meier analysis. RESULTS: Patients with ≥1 prescription fill of ruxolitinib (n = 2,787) had lower mean rates (per patient per month [PPPM]) versus patients who did not fill a prescription for ruxolitinib (n = 7,262) for hospitalizations (0.16 vs 0.32), length of inpatient stay (0.16 vs 2.44 days), emergency department visits (0.10 vs 0.14), physician office visits (4.68 vs 6.25), skilled nursing facility stays (0.02 vs 0.12), home health/durable medical equipment services (0.32 vs 0.47), and hospice visits (0.30 vs 1.70). Monthly medical costs were numerically lower in patients who had ≥1 fill of ruxolitinib versus those who did not fill a prescription for ruxolitinib ($6,553 vs $12,929), largely driven by inpatient costs ($3,428 vs $6,689). Pharmacy costs were $10,065 and $987 in patients who filled versus did not fill ≥1 prescription for ruxolitinib, respectively; total PPPM all-cause healthcare costs were $16,618 and $13,916, respectively. The median OS was 37.5 and 18.7 months for the cohorts of patients who filled versus did not fill ≥1 prescription for ruxolitinib, respectively (hazard ratio = 0.63, 95% CI = 0.59 - 0.67). CONCLUSIONS: Ruxolitinib is associated with reduced HCRU and direct costs of medical care in addition to increased survival, suggesting it to be a cost-effective advance for patients with MF.

Myelofibrosis is a rare bone marrow cancer. People with this disease do not live as long as the general population. They have difficult symptoms, can tire easily, and may have a large spleen that can be uncomfortable. Ruxolitinib is a treatment for myelofibrosis that can improve symptoms and help patients live longer.This study asked how treating patients with ruxolitinib affected three things. (1) How often do they go to a healthcare provider? (2) How much do they spend on their healthcare? (3) How long do they live? The authors looked at Medicare records to answer these questions.The study found that treated patients visited hospitals, doctors' offices, and other services less often. When they did require hospital care, they stayed in the hospital for a shorter amount of time. As a result, treated patients spent about half as much on these services. However, patients treated with ruxolitinib spent more at the pharmacy. Finally, treated patients lived about twice as long as those who were never treated with ruxolitinib. These findings suggest that ruxolitinib is worthwhile for patients with myelofibrosis.

Healthcare Resource Utilization and Costs of Steroid-Associated Complications in Patients With Graft-Versus-Host Disease.

Acute and chronic graft-versus-host disease (aGVHD/cGVHD) are serious conditions occurring after allogeneic hematopoietic cell transplantation (HCT). Steroids are the most common first-line therapy; however, they are frequently associated with numerous morbid complications. To describe the healthcare resource utilization (HCRU) and costs of steroid-related complications in patients receiving systemic steroids for GVHD. This retrospective study used medical and pharmacy claims from the Optum Research database. Eligible patients were diagnosed with GVHD (aGVHD, cGVHD, or both) after HCT and were treated with systemic steroids between July 1, 2010, and August 31, 2019. The index date was the date of the first claim for systemic steroids after GVHD diagnosis. The baseline period was the 6 months before the index date, and the follow-up period was 2 years after the index date. Outcome variables included HCRU and costs associated with steroid complications, grouped into 4 categories: bone/muscle, gastrointestinal, infection, and metabolic/endocrine. A multivariate analysis was used to assess the cost ratio associated with the presence of each steroid complication; the linear model was adjusted for baseline patient characteristics and types of steroid conditions identified during follow-up. Another multivariate analysis assessed the hazard ratio for hospitalization associated with each steroid complication using a Cox proportional hazards regression model adjusted for the time-varying presence of each complication category. A total of 689 patients were studied (median age, 55 years; male, 60%); 22% had aGVHD only, 21% had cGVHD only, and 39% had both types of GVHD. After 2 years of follow-up, 97% had at least 1 steroid-associated complication. The most common complication category was infection (79.5%), followed by metabolic/endocrine (32.4%), gastrointestinal (29.2%), and bone/muscle conditions (19.7%). About two thirds (66%) of patients with any steroid complication had ≥1 hospitalization requiring a median (interquartile range [IQR]) of 20 (8-43) hospital days. Patients with an infection experienced the highest hospitalization rate (72%) and thus the highest associated costs. The total mean (median [IQR]) healthcare cost potentially related to steroid complications was $164,787 ($50,834 [$8865-$182,693]), and the largest expense was hospitalization (mean [median {IQR}], $140,637 [$26,782 {$0-$141,398}]). Of the different steroid complications, infections were associated with the highest cost (mean [median {IQR}], $167,473 [$57,680 {$16,261-$178,698}]). In addition, a significantly higher total adjusted cost was associated with the presence of an infection, gastrointestinal complication, or bone/muscle complication in patients with GVHD versus the absence of each complication (all P < .001). Complications occurring after steroid treatment for GVHD may add substantially to the HCRU and costs associated with GVHD management. Infections in particular required inpatient care and were associated with the highest economic burden.

Thrombotic events and mortality risk in patients with newly diagnosed polycythemia vera or essential thrombocythemia.

Patients with polycythemia vera (PV) and essential thrombocythemia (ET) have increased thrombotic risk. This retrospective, real-world analysis of Medicare patients (age ≥ 65 years) newly diagnosed with high-risk PV or intermediate-/high-risk ET compared mortality risk among those with versus without thrombotic events during the study period. Patients diagnosed with PV or ET with ≥ 1 inpatient or ≥ 2 outpatient claims (January 1, 2010-December 31, 2017; index was date of first qualifying claim) were included. The study included 50,405 Medicare beneficiaries with PV and 124,569 with ET. During follow-up (median [range]: PV, 34.5 [0-97.3] months; ET, 25.5 [0-97.4] months), 14,334 patients (28.4%) with PV and 30,478 (24.5%) with ET experienced thrombotic events (most commonly ischemic stroke [PV, 46.0%; ET, 42.5%]. Mortality risk was increased for patients with versus without post-index thrombosis for both PV (adjusted hazard ratio [aHR; 95% CI], 18.6 [16.1-21.6]; P < 0.001) and ET (aHR [95% CI], 25.2 [23.1-27.5]; P < 0.001). Median survival was shorter for patients who experienced a thrombotic event ≤ 1 year post-index versus those who did not (PV, 5.1 years vs not reached; ET, 3.7 vs 6.7 years; both P < 0.001). These findings highlight the importance of thrombosis risk mitigation in PV and ET management.

Healthcare resource utilization and costs among patients with steroid-resistant chronic graft-versus-host disease in the United States: a retrospective claims database analysis.

BACKGROUND: Chronic graft-versus-host disease (cGVHD) is the most serious non-relapse complication affecting long-term allogeneic hematopoietic cell transplantation (HCT) survivors. We describe healthcare resource utilization (HCRU) and costs in patients with steroid-resistant (SR) cGVHD versus no GVHD up to 360 and 720 days post-HCT. METHODS: Claims from the Optum Research Database were used to identify patients aged ≥12 years who underwent allogeneic HCT (index date) in the United States from 01 January 2010 to 31 August 2016 with diagnosis of cGVHD (within the study period or unspecified GVHD beyond 120 days post-HCT [SR defined as additional therapy ≥7 days after initiation of systemic steroids]) or no GVHD at any time. All-cause HCRU and costs were compared in patients with SR cGVHD (1-year analysis, n = 296; 2-year analysis, n = 178) versus no GVHD (1-year analysis, n = 227; 2-year analysis, n = 158). RESULTS: Most patients with SR cGVHD (75%) received ≥4 lines of therapy during follow-up. Patients with SR cGVHD had significantly more median office visits (49 vs. 27), outpatient visits (69 vs. 24), emergency department visits (1 vs. 0), and inpatient admissions (2 vs. 1) within 1 year post-HCT versus patients with no GVHD (all p<.001); HCRU was also higher in the 2-year period. Median total all-cause costs were significantly higher (p<.001) for patients with SR cGVHD versus no GVHD in the 1-year ($372,254 vs. $219,593) and 2-year ($532,673 vs. $252,909) follow-up periods. CONCLUSIONS: Patients with SR cGVHD required multiple lines of therapy and used significantly more outpatient and inpatient resources resulting in higher costs versus patients with no GVHD.

Real-world risk assessment and treatment initiation among patients with myelofibrosis at community oncology practices in the United States.

Myelofibrosis (MF) is a chronic myeloproliferative neoplasm with a prevalence of 4 to 6 per 100,000 people in the USA. Treatment recommendations are risk-adapted. This study was conducted to evaluate how physicians risk-stratify patients at the time of MF diagnosis, the accuracy of the risk stratification, and its effect on treatment selection. Medical charts were reviewed at US community hematology/oncology practices in the Cardinal Health Oncology Provider Extended Network; patient clinical characteristics, risk stratification, and treatment data were collected. Physician-assigned risk categorizations were compared with data-derived risk categorizations based on the International Prognostic Scoring System, the system recommended at diagnosis. A total of 491 patients diagnosed with MF between 2012 and 2016 (mean [SD] age at diagnosis, 65.4 [11.8] years; 54.8% male, 69.2% with primary MF) were included. Risk categorization was not assigned for 30.1% of patients. Of the patients with a physician-assigned risk categorization (n = 343), a scoring system was used in 49.9%. Compared with data-derived risk categorizations, 42.9% of physician-assigned risk categorizations were incorrect; 85.0% of incorrect physician-assigned risk categorizations were underestimations. Notably, 38.5% of patients with data-derived intermediate- or high-risk categorizations did not initiate treatment within 120 days of diagnosis. Among patients with data-derived intermediate risk, those with an underestimated physician-assigned risk categorization were significantly less likely to receive treatment within 120 days of diagnosis (51.6% with correct physician-assigned categorization vs 18.5% with underestimated risk categorization; P = 0.0023). These results highlight the gap in risk assessment and the importance of accurate risk stratification at diagnosis.

Healthcare resource utilization and costs associated with acute graft-versus-host disease following allogeneic hematopoietic cell transplantation.

PURPOSE: The contribution of acute graft-versus-host disease (GVHD) to healthcare resource utilization (HCRU) and costs following allogeneic hematopoietic cell transplantation (HCT) has not been extensively investigated. The objective of this study was to estimate both inpatient and outpatient HCRU and costs associated with acute GVHD during the 100-day and 1-year periods after allogeneic HCT in the USA. METHODS: A retrospective analysis of administrative claims from the Optum® Research Database of patients aged ≥ 12 years who received HCT between 2010 and 2016 was conducted. Costs and HCRU among patients with acute GVHD and no GVHD were compared during the 100-day (acute GVHD, n = 723; no GVHD, n = 385) and 360-day (acute GVHD, n = 445; no GVHD, n = 227) periods after HCT. RESULTS: Patients with acute GVHD had significantly more (P < 0.001) mean office visits (47 vs 32), hospital outpatient visits (71 vs 35), and inpatient stays (2.8 vs 1.1) than patients with no GVHD during 360 days post-HCT; similar findings were observed over the 100-day period. Mean total all-cause costs were significantly higher (P < 0.001) for patients with acute GVHD versus no GVHD during both post-HCT periods (100-day, $316,458 vs $215,229; 360-day, $466,720 vs $263,568). Additional factors associated with increased 360-day costs included young age (12-17 years; P < 0.001) and peripheral blood as graft source (P = 0.03). CONCLUSION: Acute GVHD was associated with significant HCRU and costs in the first 100 days of transplant, increasing over the first year post-HCT. Inpatient care was the primary driver, but outpatient care and related costs were also increased.

Inpatient Healthcare Resource Utilization, Costs, and Mortality in Adult Patients with Acute Graft-versus-Host Disease, Including Steroid-Refractory or High-Risk Disease, following Allogeneic Hematopoietic Cell Transplantation.

Acute graft-versus-host disease (GVHD) contributes to poor outcomes following allogeneic hematopoietic cell transplantation (HCT). Data are limited regarding the economic burden of acute GVHD, particularly steroid-refractory or high-risk (SR/HR) disease. This retrospective analysis of the Premier Healthcare Database reports inpatient healthcare resource utilization (HCRU), costs, and mortality during initial hospitalization for allogeneic HCT and through 100 days post-HCT among patients who developed acute GVHD, including a subgroup with SR/HR disease, compared with patients without GVHD. The analysis included adults discharged for first HCT between January 1, 2011, and June 30, 2016 (acute GVHD, n = 906; SR/HR acute GVHD, n = 158; no GVHD, n = 1529). During the initial hospitalization for HCT, patients with acute GVHD and SR/HR acute GVHD (n = 455 and 125, respectively) had significantly longer median lengths of stay (31 and 46 days versus 24 days) and higher median total costs ($153,849 and $205,880 versus $97,417) versus patients with no GVHD (n = 1529; P < .0001 for all). During the 100-day post-HCT period, patients with acute GVHD and SR/HR acute GVHD had higher readmission rates (78.3% and 77.2% versus 28.3%; P < .0001) and inpatient mortality rates (20.2% and 35.4% versus 8.9%; P < .0001) versus patients with no GVHD. In summary, acute GVHD, especially SR/HR disease, is associated with longer inpatient stays, higher readmission rates, and higher inpatient mortality compared with no GVHD.

Relationship between symptom burden and disability leave among patients with myeloproliferative neoplasms (MPNs): findings from the Living with MPN patient survey.

Patients with myeloproliferative neoplasms (MPNs) experience burdensome symptoms that negatively affect their quality of life. How MPN symptoms relate with medical disability leave (MDL) among patients with the disease has not been previously examined. Using data collected from the Living with MPNs patient survey, symptom burden and functional status were compared in patients who reported taking MDL due to their MPN versus patients who reported no changes in employment status. Among 592 patients who were employed full- or part-time at diagnosis, 24.8% reported taking ≥ 1 MDL and 49.4% reported no change in employment status as a result of their MPN. Of the patients who took MDL, 29.9% took ≥ 2 MDLs, and most patients (62.6%) did not return to work. All 10 symptoms comprising the MPN Symptom Assessment Form were significantly more frequent and severe in patients who took MDL compared with those who had no employment change. Furthermore, functional impairments were also significantly more frequent among patients who went on MDL versus those with no employment change. Effective management of MPN-related symptoms may reduce disability leave among patients with high symptom burden.

Mortality, length of stay and costs associated with acute graft-versus-host disease during hospitalization for allogeneic hematopoietic stem cell transplantation.

OBJECTIVE: Acute graft-versus-host disease (aGVHD) is a common and life-threatening complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). The extent to which aGVHD increases inpatient costs associated with allo-HSCT has not been thoroughly evaluated. In this analysis, mortality, hospital length of stay (LOS) and costs associated with aGVHD during allo-HSCT admissions are evaluated. METHODS: This is a retrospective analysis of discharge records from the National Inpatient Sample database for patients receiving allo-HSCT between 1 January 2009 and 31 December 2013. Allo-HSCT discharges with an aGVHD diagnosis were included in the aGVHD group and those without any graft-versus-host disease (GVHD) diagnosis comprised the non-GVHD group. Mortality, LOS and costs were compared between the two groups, as well as within subgroups, including age (<18 vs. ≥18 years) and survival status (alive vs. deceased) at discharge. RESULTS: Overall, mortality (16.2% vs. 5.3%; p < .01), median hospital LOS (42.0 vs. 26.0 days; p < .01) and median total costs ($173,144 vs. $98,982; p < .01) were significantly increased in patients with aGVHD versus those without GVHD during hospitalizations for allo-HSCT, irrespective of age group. Patients with aGVHD who were <18 years of age had a lower mortality rate but greater hospital LOS and total costs versus patients aged ≥18 years. Patients who died during allo-HSCT hospitalization had longer LOS and incurred greater costs than those who survived in both the aGVHD and non-GVHD groups. CONCLUSION: Occurrence of aGVHD during allo-HSCT admissions resulted in a tripling of the mortality rate and a near doubling of hospital LOS and total costs. In addition, death during allo-HSCT hospitalizations was associated with greater healthcare utilization and costs. Effectively mitigating aGVHD may improve survival and substantially reduce hospital LOS and costs for allo-HSCT.

Cytoreductive treatment patterns among US veterans with polycythemia vera.

BACKGROUND: Polycythemia vera (PV) is a myeloproliferative neoplasm associated with increased thrombotic and cardiovascular risk, which are key contributors to patient morbidity and mortality. The Veterans Health Administration (VHA) is the largest integrative health network in the United States. Available data concerning patients with PV in this population are limited. METHODS: This retrospective observational study evaluated the characteristics, management, and outcomes of patients with PV in the VHA Medical SAS® Dataset (October 1, 2005, to September 30, 2012). Inclusion criteria were ≥ 2 claims for PV (ie, PV diagnostic code was recorded) ≥30 days apart during the identification period, age ≥ 18 years, and continuous health plan enrollment from ≥12 months before the index date until the end of follow-up. All data were analyzed using descriptive statistics. RESULTS: The analysis included 7718 patients (median age, 64 years; male, 98%; white, 64%). The most common comorbidities before the index date were hypertension (72%), dyslipidemia (54%), and diabetes (24%); 33% had a history of smoking. During the follow-up period (median, 4.8 years), most patients did not receive treatment with cytoreductive therapy, including phlebotomy (53%), or antiplatelet agents, such as aspirin (57%). The thrombotic and cardiovascular event rates per 1000 patient-years were 60.5 and 83.8, respectively. Among patients who received cytoreductive treatment, the thrombotic event rate was 48.9 per 1000 patient-years. The overall mortality rate was 51.2 per 1000 patient-years. CONCLUSION: The notable rates of thrombotic and cardiovascular events observed in this analysis, even among patients receiving cytoreductive treatment, highlight the important unmet clinical needs of patients with PV in the VHA.

Cost and Consequences of Nonadherence With Oral Bisphosphonate Therapy: Findings From a Real-World Data Analysis.

BACKGROUND: Adherence to osteoporosis treatment remains poor despite available treatments and physician and patient education. This study aims to determine the effect of low adherence in real-world data. OBJECTIVE: To examine the association between adherence with oral bisphosphonate therapy and fracture risk as well as health care resource utilization. METHODS: Women included in this retrospective analysis were 55 years or older and had started oral bisphosphonate therapy between 2005 and 2011 in a large not-for-profit health care center in Israel. Adherence to therapy was measured by the medication possession ratio (MPR) during the first year from therapy initiation. Patients with MPR lower than 70% were considered nonadherent. Study outcomes were osteoporotic fracture events and health care utilization (including physician visits and hospitalizations) during the second year from therapy initiation. RESULTS: Among the 17 770 women included in the analysis (mean age = 66.5 years; SD = ±8.3 years), 48.9% were nonadherent to therapy during the first year of treatment. Osteoporotic fracture risks during the second year among adherent and nonadherent patients were 2.1% and 2.5%, respectively (P = 0.1). When analysis was limited to patients 75 years or older, nonadherence with bisphosphonates was associated with an adjusted odds ratio of 1.49 (95% CI = 1.08-2.04) for osteoporotic fractures compared with adherent patients. Nonadherent patients had 13.4% higher medical costs than their adherent counterparts among patients 75 years and older (P = 0.002). CONCLUSIONS: In patients 75 years and older, nonadherence with oral bisphosphonates can be associated with significantly greater short-term risk of osteoporotic fractures and higher utilization of health care services.

Undertreatment of osteoporosis and the role of gastrointestinal events among elderly osteoporotic women with Medicare Part D drug coverage.

OBJECTIVES: To examine the rate of osteoporosis (OP) undertreatment and the association between gastrointestinal (GI) events and OP treatment initiation among elderly osteoporotic women with Medicare Part D drug coverage. METHODS: This retrospective cohort study utilized a 20% random sample of Medicare beneficiaries. Included were women ≥66 years old with Medicare Part D drug coverage, newly diagnosed with OP in 2007-2008 (first diagnosis date as the index date), and with no prior OP treatment. GI event was defined as a diagnosis or procedure for a GI condition between OP diagnosis and treatment initiation or at the end of a 12-month follow-up, whichever occurred first. OP treatment initiation was defined as the use of any bisphosphonate (BIS) or non-BIS within 1 year postindex. Logistic regression, adjusted for patient characteristics, was used to model the association between 1) GI events and OP treatment initiation (treated versus nontreated); and 2) GI events and type of initial therapy (BIS versus non-BIS) among treated patients only. RESULTS: A total of 126,188 women met the inclusion criteria: 72.1% did not receive OP medication within 1 year of diagnosis and 27.9% had GI events. Patients with a GI event were 75.7% less likely to start OP treatment (odds ratio [OR]=0.243; P<0.001); among treated patients, patients with a GI event had 11.3% lower odds of starting with BIS versus non-BIS (OR=0.887; P<0.001). CONCLUSION: Among elderly women newly diagnosed with OP, only 28% initiated OP treatment. GI events were associated with a higher likelihood of not being treated and, among treated patients, a lower likelihood of being treated with BIS versus non-BIS.

The burden of unintended pregnancies in Brazil: a social and public health system cost analysis.

BACKGROUND: Unintended pregnancy (UP) is an unmet medical need with consequences worldwide. We evaluate the costs of UP based on pregnancies in Brazil from for the year 2010. METHODS: The consequences of UP were evaluated using decision analysis based on pregnancy rates and outcomes as miscarriage, induced abortion, and live birth, which were factored into the analysis. The model discriminated between maternal and child outcomes and accounted for costs (in Brazilian currency [Real$, R$]) within the Brazilian public health service attributed to preterm birth, neonatal admission, cerebral palsy, and neonatal and maternal mortality. Event probabilities were obtained from local resources. RESULTS: We estimate that 1.8 million UPs resulted in 159,151 miscarriages, 48,769 induced abortions, 1.58 million live births, and 312 maternal deaths, including ten (3%) attributed to unsafe abortions. The total estimated costs attributed to UP are R$4.1 billion annually, including R$32 million (0.8%) and R$4.07 billion (99.2%) attributed to miscarriages and births and complications, respectively. Direct birth costs accounted for approximately R$1.22 billion (30.0%), with labor and delivery responsible for most costs (R$988 million; 24.3%) for the year 2010. The remainder of costs were for infant complications (R$2.84 billion; 72.3%) with hospital readmission during the first year accounting for approximately R$2.15 billion (52.9%). Based on the national cost, we estimate the cost per UP to be R$2,293. CONCLUSION: Despite weaknesses in precise estimates in annual pregnancies and induced abortions, our estimates reflect the costs of UP for different pregnancy outcomes. The main costs associated with UP are in those carried to parturition. The health cost of abortion represents a small proportion of total costs as these are paid for outside of the public health system. Consequently, reductions in UP will generate not only cost savings, but reductions in woman and child morbidity and mortality.

Inappropriate use of combined hormonal contraceptives for birth control among women of reproductive age in the United States.

OBJECTIVE: To describe the extent of inappropriate use of combined hormonal contraceptives (CHC) according to the United States Medical Eligibility Criteria (U.S. MEC). METHODS: We analyzed Kantar Health's 2010 U.S. National Health and Wellness Survey data, which is an annual population-based survey of 75,000 U.S. adults via internet. A stratified random sampling framework was used to construct a sample that reflects the U.S. census by age, gender, and ethnicity. The analysis included nonpregnant females aged 18-44 years who used CHC, including oral, patch, or vaginal rings in the past 6 months. Women classified into category 3 (theoretical or proven risks usually outweigh the advantages of using the method) or 4 (unacceptable health risk) according to the U.S. MEC were defined as having high-risk conditions, or inappropriate CHC use. The proportions of women who had inappropriate CHC use were then projected to the U.S. population by diseases/conditions and demographic characteristics incorporating sampling weights. RESULTS: We identified 2963 adult females of reproductive age (mean 29.3±6.0) (i.e., 20.4% of all adult females of reproductive age in the database) as being CHC users. Among them, 23.7% (95% CI: 22.8%-24.5%) had at least one high-risk condition and 9.3% (95% CI: 9.2%-9.4%) had at least one condition of unacceptable risk. The three most common high-risk conditions were migraine (12.7%), multiple risk factors for arterial cardiovascular disease (9.3%), and hypertension (6.1%). Women with relatively higher proportions of inappropriate CHC use were age ≥35, not finished college, and Medicaid recipients. CONCLUSIONS: A large portion of women used CHC inappropriately. Hormone-free and progestin-only contraceptives are available options with potentially less risk for them.

Costs associated with febrile neutropenia in the US.

BACKGROUND AND OBJECTIVE: Febrile neutropenia (FN) is a potentially life-threatening condition that may develop in cancer patients treated with myelosuppressive chemotherapy and result in considerable costs. This study was designed to estimate US healthcare utilization and costs in those experiencing FN by location of care, tumour type and mortality. METHODS: Cancer patients who received chemotherapy between 2001 and 2006 were identified from the HealthCore Integrated Research Database®, a longitudinal claims database with enrolment, medical, prescription and mortality information covering 12 health plans and more than 20 million US patients. Patients who experienced FN were prospectively matched using propensity score methods within each tumour type of interest (non-Hodgkin's lymphoma, breast, lung, colorectal and ovarian cancer) to those not experiencing FN. Health resource utilization was compared per patient per month for unique prescriptions and visits (inpatient and outpatient) over the length of follow-up. Healthcare total paid costs adjusted to 2009 US dollars per patient per month were examined by FN group (FN vs non-FN, FN died vs FN survived), by source of care (physician office visit, outpatient services, hospitalization and prescriptions) and by tumour type. The number of unique FN-related encounters (inpatient and outpatient) and the number of patients experiencing at least one FN-related encounter were examined. The costs per encounter were tabulated. FN encounters differ from FN episodes in that a single FN episode may include multiple FN encounters (i.e. a patient is seen multiple times [encounters] for treatment of a single FN event [episode]). RESULTS: A total of 5990 patients each were successfully matched between the FN and non-FN (control) groups. Health resource utilization was generally higher in those with FN than in controls. FN patients incurred greater costs (mean ± SD: $US9628 ± 12 517 per patient-month) than non-FN patients ($US8478 ± 12 978). Chemotherapy comprised the majority of costs for both FN (33.5%) and non-FN (40.6%) patients. The largest cost difference by categorical source of care was for hospitalization (p < 0.001). FN patients who died had the highest mean total costs compared with FN surviving patients ($US21 214 ± 25 596 per patient-month vs $US8227 ± 8850, respectively). Follow-up time for those surviving was, on average, 6.6 months longer. Hospitalization accounted for 53.1% of costs in those experiencing mortality with FN, while chemotherapy accounted for the majority of costs (37.1%) in surviving FN patients. A total of 6574 patients with at least one FN encounter experienced a total of 55 726 unique FN-related encounters, 90% of which were outpatient in nature. The majority of FN-related encounters (79%) occurred during the first chemotherapy course. The average costs for FN encounters were highest for inpatient encounters, $US22 086 ± 43 407, compared with $US985 ± 1677 for outpatient encounters. CONCLUSIONS: The occurrence of FN in cancer patients receiving chemotherapy results in greater healthcare resource utilization and costs, with FN patients who die accounting for the greatest healthcare costs. Most FN patients experience at least one outpatient FN encounter, and the total cost of treatment for FN continues to be high.

Direct healthcare costs of osteoporosis-related fractures in managed care patients receiving pharmacological osteoporosis therapy.

BACKGROUND: Osteoporosis is a common condition and the economic burden of osteoporosis-related fractures is significant. While studies have reported the incremental or attributable costs of osteoporosis-related fracture, data on the economic impact of osteoporosis-related fractures in commercial health plan populations are limited. OBJECTIVE: To estimate the direct costs of osteoporosis-related fractures among pharmacologically treated patients in a large, commercially insured population between 2005 and 2008. METHODS: In this retrospective cohort study, patients were identified from a large, commercially insured population with integrated pharmacy and medical claims. Inclusion criteria were age 45-64 years; one or more osteoporosis medication claim(s) with first (index) claim between 1 January 2005 and 30 April 2008; and continuous insurance coverage for ≥12 months pre-index and ≥6 months post-index. Patients with pre-index Paget's disease or malignant neoplasm; skilled nursing facility stay; combination therapy at index; or fracture ≤6 months post-index were excluded. A generalized linear model compared differences in 6-month pre-/post-event costs for patients with and without fracture. Propensity score weighting was used to ensure comparability of fracture and non-fracture patients. Generalized estimating equations accounted for repeated measures. RESULTS: The study included 49,680 patients (2613 with fracture) with a mean (SD) age of 56.4 (4.7) years; 95.9% were female. Mean differences between pre- and post-event direct costs were $US14,049 (95% CI 7670, 20,428) for patients with vertebral fractures, $US16,663 (95% CI 11,690, 21,636) for patients with hip fractures, and $US7582 (95% CI 6532, 8632) for patients with other fractures. After adjusting for covariates, osteoporosis-related fractures were associated with an additional $US9996 (95% CI 8838, 11,154; p < 0.0001) in direct costs per patient across all fracture types during the 6 months following fracture. CONCLUSION: Patients with osteoporosis-related fractures were found to incur nearly $US10,000 in estimated additional direct healthcare costs in the 6 months post-fracture, compared with patients with no fracture. Reduced fracture risk may lower associated direct healthcare costs.

Analysis of the comparative effectiveness of 3 oral bisphosphonates in a large managed care organization: adherence, fracture rates, and all-cause cost.

BACKGROUND: Despite widespread availability and use of oral bisphosphonates, fracture rates and associated medical costs are still high. Differences in fracture risk among these agents, if any, have not been quantified due to the lack of high-quality, head-to-head, randomized, controlled trials assessing this outcome. Randomized, placebo-controlled trials have shown that alendronate and risedronate reduce rates of both vertebral and nonvertebral fractures, whereas only reduction in vertebral fractures has been found for ibandronate. OBJECTIVE: To determine if there were any differences among 3 oral bisphosphonates in adherence, total cost of care, and effectiveness in reducing fracture rates in a large managed care population. METHODS: Administrative, longitudinal pharmacy and medical claims data were obtained from 14 geographically diverse health plans in the United States covering approximately 14 million members. Sampled members had at least 1 pharmacy claim for alendronate, risedronate, or ibandronate during the intake period (January 1, 2005, through October 31, 2007). The date of the first pharmacy claim for osteoporosis medications within the intake period was the index date. Members were followed for either 12, 24, or 36 months, depending on length of continuous health plan eligibility. Medication possession ratio (MPR) was measured using a total days supply that was calculated by multiplying the total quantity dispensed by the suggested days supply per unit of dispensing based on manufacturer-recommended dosing. For members who switched bisphosphonate strengths or medications, the estimated days supply was summed for all osteoporosis medications during the follow-up, including overlapping days supply. Outcomes included (a) the first incident fracture and percentages of members with at least 1 fracture after 6 months post-index; (b) the number of days from index to the first incident fracture, measured as time to event in Cox proportional hazards regression analysis; and (c) total all-cause health care costs (health plan allowed amount including member cost share). RESULTS: A total of 45,939 members were included (n = 24,909 alendronate, n = 13,834 risedronate, n = 7,196 ibandronate). In the 12-month analysis, MPRs were comparable (means = 0.57-0.58) for the 3 medications. After 24 months, MPRs had dropped for all medications, but those of both alendronate (mean = 0.50, 95% CI = 0.49-0.50) and risedronate (mean = 0.50, 95% CI = 0.49-0.51) were slightly higher than that of ibandronate (mean = 0.47, 95% CI = 0.46-0.48). At 36 months, again the MPRs had dropped for all 3 medications (means = 0.44-0.47) but were similar. There were no statistically significant differences among agents in the percentages of subjects with at least 1 fracture at 12, 24, or 36 months (36-month rates: alendronate 4.41%, risedronate 4.38%, ibandronate 6.28%, P = 0.102). The numbers of subjects with fracture(s) per month of follow-up were 0.0020 for alendronate, 0.0021 for risedronate, and 0.0022 for ibandronate (P = 0.087 overall). However, after adjusting for member characteristics, alendronate users had a 12% lower risk of experiencing any incident fracture than ibandronate users (hazard ratio = 0.88, 95% CI = 0.78-0.99, P = 0.034) within the follow-up period. In the first 12 post-index months, ibandronate users had higher mean [SD] unadjusted total all-cause health care costs ($7,464 [$15,975]) compared with alendronate ($7,233 [$16,671]) and risedronate ($ 6,983 [$16,870], P less than 0.001 for both comparisons), differences of approximately $19 per month and $40 per month, respectively. The results of the unadjusted 24-month analysis were similar, but there were no significant cost differences at 36 months. Total cost differences for the 3 medication groups were nonsignificant at 12, 24, and 36 months after adjusting for member characteristics. CONCLUSIONS: This retrospective analysis of an administrative claims database in a large managed care population showed similar rates of adherence and total adjusted all-cause health care costs for alendronate, risedronate, and ibandronate. Absolute unadjusted rates of fracture were small and did not significantly differ among agents, but after controlling for differences in member characteristics, the risk of fracture was 12% lower for alendronate users than for ibandronate users.

Impact of Medicaid/ SCHIP disenrollment on health care utilization and expenditures among children: a longitudinal analysis.

This study examines the impact of disenrolling from Medicaid/State Children's Health Insurance Programs (SCHIP) on health care utilization and expenditures among children using the 1996-2005 Medical Expenditure Panel Survey data. Changes in expenditures and utilization upon Medicaid/SCHIP disenrollment were examined for two disenrollment groups, children who became uninsured and those who transitioned to private insurance; relative to a control group, those continuously enrolled in Medicaid/SCHIP during the study period. In multivariate analysis, a modified two-part model and difference-in-difference analytic approach were used. The dependent variables were changes in total expenditures and changes in utilization (i.e., well-child visits, physician visits, emergency room visits, hospitalizations, and prescription drug use) from pre- to post-disenrollment round. This study found that losing Medicaid/SCHIP coverage is associated with decreased preventive care utilization among children, regardless of the insurance status post-disenrollment. In addition, children who become uninsured following Medicaid/SCHIP disenrollment may also experience reductions in physician visits and prescription drug use.
