Factors associated with discontinuation of treatment for pulmonary arterial hypertension in the United States.

Information on factors leading to pulmonary arterial hypertension (PAH) treatment discontinuation is limited. This study analyzed 12,902 new PAH medication users to identify predictors of treatment discontinuation. Treatment by accredited pulmonary hypertension centers and combination therapy with PAH agents from different classes were less likely to result in discontinuation.

Effectiveness of Single-Tablet Combination Therapy in Improving Adherence and Persistence and the Relation to Clinical and Economic Outcomes.

Background: Single-tablet combination therapies (STCTs) combine multiple drugs into one formulation, making drug administration more convenient for patients. STCTs were developed to address concerns with treatment adherence and persistence, but the impact of STCT use is not fully understood across indications. Objectives: We conducted a systematic literature review (SLR) to examine STCT-associated outcomes across 4 evidence domains: clinical trials, real-world evidence (RWE), health-related quality of life (HRQoL) studies, and economic evaluations. Methods: Four SLRs were conducted across the aforementioned domains. Included studies compared STCTs as well as fixed-dose combinations ([FDCs] of non-tablet formulations) with the equivalent active compounds and doses in loose-dose combinations (LDCs). Original research articles were included; case reports, case series, and non-English-language sources were excluded. Databases searched included EconLit, Embase, and Ovid MEDLINE® ALL. Two independent reviewers assessed relevant studies and extracted data. Conflicts were resolved with a third reviewer or consensus-based discussion. Results: In all, 109 studies were identified; 27 studies were identified in more than one SLR. Treatment adherence was significantly higher in patients receiving FDCs vs LDCs in 12 of 13 RWE studies and 3 of 13 clinical trials. All 18 RWE studies reported higher persistence with FDCs. In RWE studies examining clinical outcomes (n = 17), 14 reported positive findings with FDCs, including a reduced need for add-on medication, blood pressure control, and improved hemoglobin A1C. HRQoL studies generally reported numerical improvements with STCTs or similarities between STCTs and LDCs. Economic outcomes favored STCT use. All 6 cost-effectiveness or cost-utility analyses found FDCs were less expensive and more efficacious than LDCs. Four budget impact models found that STCTs were associated with cost savings. Medical costs and healthcare resource use were generally lower with FDCs than with LDCs. Discussion: Evidence from RWE and economic studies strongly favored STCT use, while clinical trials and HRQoL studies primarily reported similarity between STCTs and LDCs. This may be due to clinical trial procedures aimed at maximizing adherence and HRQoL measures that are not designed to evaluate drug administration. Conclusions: Our findings highlight the value of STCTs for improving patient adherence, persistence, and clinical outcomes while also offering economic advantages.

A claims-based, machine-learning algorithm to identify patients with pulmonary arterial hypertension.

Many patients with pulmonary arterial hypertension (PAH) experience substantial delays in diagnosis, which is associated with worse outcomes and higher costs. Tools for diagnosing PAH sooner may lead to earlier treatment, which may delay disease progression and adverse outcomes including hospitalization and death. We developed a machine-learning (ML) algorithm to identify patients at risk for PAH earlier in their symptom journey and distinguish them from patients with similar early symptoms not at risk for developing PAH. Our supervised ML model analyzed retrospective, de-identified data from the US-based Optum® Clinformatics® Data Mart claims database (January 2015 to December 2019). Propensity score matched PAH and non-PAH (control) cohorts were established based on observed differences. Random forest models were used to classify patients as PAH or non-PAH at diagnosis and at 6 months prediagnosis. The PAH and non-PAH cohorts included 1339 and 4222 patients, respectively. At 6 months prediagnosis, the model performed well in distinguishing PAH and non-PAH patients, with area under the curve of the receiver operating characteristic of 0.84, recall (sensitivity) of 0.73, and precision of 0.50. Key features distinguishing PAH from non-PAH cohorts were a longer time between first symptom and the prediagnosis model date (i.e., 6 months before diagnosis); more diagnostic and prescription claims, circulatory claims, and imaging procedures, leading to higher overall healthcare resource utilization; and more hospitalizations. Our model distinguishes between patients with and without PAH at 6 months before diagnosis and illustrates the feasibility of using routine claims data to identify patients at a population level who might benefit from PAH-specific screening and/or earlier specialist referral.

Predicted Economic Benefits of a Novel Biomarker for Earlier Sepsis Identification and Treatment: A Counterfactual Analysis.

To estimate the potential clinical and health economic value of earlier sepsis identification in the emergency department using a novel diagnostic marker, monocyte distribution width. DESIGN: The analysis was conducted in two phases: 1) an analysis of the pivotal registration trial evidence to estimate the potential benefit of monocyte distribution width for early sepsis identification and (2) a cost-consequence analysis to estimate the potential economic and clinical benefits that could have resulted from earlier administration of antibiotics for those patients. SETTING: Sepsis identified in the emergency department which led to inpatient hospitalizations. PATIENTS: Adult sepsis patients admitted through the emergency department. INTERVENTIONS: None. This was a model simulation of clinical and economic outcomes of monocyte distribution width based on results from a noninterventional, multicenter clinical trial. MEASUREMENTS AND MAIN RESULTS: Among the 385 patients with sepsis, a total of 349 were eligible for inclusion. Sixty-seven percent of patients were predicted to benefit from monocyte distribution width results, resulting in an estimated mean reduction in time to antibiotics administration from 3.98 hours using standard of care to 2.07 hours using monocyte distribution width + standard of care. Based on this simulated reduction in time to antibiotics, monocyte distribution width + standard of care could have resulted in a less than or equal to 14.2% reduction (27.9% vs 32.5%) in mortality, a mean reduction of 1.48 days (10.0 vs 11.5 d) in length of stay, and $3,460 ($23,466 vs $26,926) savings per hospitalization. At the hospital level, based on an established national mean of 206 sepsis hospitalizations per hospital per year, earlier identification with monocyte distribution width is predicted to result in a total of $712,783 in annual cost savings per hospital. CONCLUSIONS: Improved early identification of sepsis using monocyte distribution width along with current standard of care is estimated to improve both clinical and economic outcomes of sepsis patients presenting in the emergency department. Further research is warranted to confirm these model projections.

Epidemiology and Costs of Sepsis in the United States-An Analysis Based on Timing of Diagnosis and Severity Level.

OBJECTIVES: To characterize the current burden, outcomes, and costs of managing sepsis patients in U.S. hospitals. DESIGN: A retrospective observational study was conducted using the Premier Healthcare Database, which represents ~20% of U.S. inpatient discharges among private and academic hospitals. Hospital costs were obtained from billing records per the cost accounting method used by each hospital. Descriptive statistics were performed on patient demographics, characteristics, and clinical and economic outcomes for the index hospitalization and 30-day readmissions. SETTING: Sepsis patient hospitalizations, including inpatient, general ward, and ICU (intermediate and/or step-down). PATIENTS: Adults over 18 years old with a hospital discharge diagnosis code of sepsis from January 1, 2010, to September 30, 2016. INTERVENTIONS: None. This was a retrospective observational study of deidentified data. MEASUREMENTS AND MAIN RESULTS: The final study cohort consisted of 2,566,689 sepsis cases, representing patients with a mean age of 65 years (50.8% female). Overall mortality was 12.5% but varied greatly by severity (5.6%, 14.9%, and 34.2%) for sepsis without organ dysfunction, severe sepsis, and septic shock, respectively. Costs followed a similar pattern increasing by severity level: $16,324, $24,638, and $38,298 and varied widely by sepsis present at admission ($18,023) and not present at admission ($51,022). CONCLUSIONS: The highest burden of incidence and total costs occurred in the lowest severity sepsis cohort population. Sepsis cases not diagnosed until after admission, and those with increasing severity had a higher economic burden and mortality on a case-by-case basis. Methods to improve early identification of sepsis may provide opportunities for reducing the severity and economic burden of sepsis in the United States.

Clinical utility of the Prostate Health Index (phi) for biopsy decision management in a large group urology practice setting.

BACKGROUND: Deciding when to biopsy a man with non-suspicious DRE findings and tPSA in the 4-10 ng/ml range can be challenging, because two-thirds of such biopsies are typically found to be benign. The Prostate Health Index (phi) exhibits significantly improved diagnostic accuracy for prostate cancer detection when compared to tPSA and %fPSA, however only one published study to date has investigated its impact on biopsy decisions in clinical practice. METHODS: An IRB approved observational study was conducted at four large urology group practices using a physician reported two-part questionnaire. Physician recommendations were recorded before and after receiving the phi test result. A historical control group was queried from each site's electronic medical records for eligible men who were seen by the same participating urologists prior to the implementation of the phi test in their practice. 506 men receiving a phi test were prospectively enrolled and 683 men were identified for the historical control group (without phi). Biopsy and pathological findings were also recorded for both groups. RESULTS: Men receiving a phi test showed a significant reduction in biopsy procedures performed when compared to the historical control group (36.4% vs. 60.3%, respectively, P < 0.0001). Based on questionnaire responses, the phi score impacted the physician's patient management plan in 73% of cases, including biopsy deferrals when the phi score was low, and decisions to perform biopsies when the phi score indicated an intermediate or high probability of prostate cancer (phi ≥36). CONCLUSIONS: phi testing significantly impacted the physician's biopsy decision for men with tPSA in the 4-10 ng/ml range and non-suspicious DRE findings. Appropriate utilization of phi resulted in a significant reduction in biopsy procedures performed compared to historical patients seen by the same participating urologists who would have met enrollment eligibility but did not receive a phi test.

Lipid-lowering treatment modifications among patients with hyperlipidemia and a prior cardiovascular event: a US retrospective cohort study.

BACKGROUND: Numerous studies demonstrate that, even with use of statins, many patients are unable to meet their LDL-C goals. This study examined modifications to statin and/or ezetimibe therapy among patients with hyperlipidemia and prior history of cardiovascular (CV) events in a US commercially insured population. METHODS: Adults (age ≥18 years) initiating statins and/or ezetimibe between 1 January 2007 and 31 December 2008 were identified from HealthCore Integrated Research Database. The index date was the initiation date of statins and/or ezetimibe. All patients had ≥1 medical claims related to myocardial infarction, unstable angina, ischemic stroke, transient ischemic attack, coronary artery bypass graft, or percutaneous coronary intervention within 12 months prior to the index date. Treatment modifications to statins and/or ezetimibe initiated on the index date (index therapy) included permanent discontinuation of any lipid lowering therapy (LLT), rechallenge, switching, subtraction, augmentation, and dose changes. RESULTS: Among 17,902 patients, around 90% initiated with statin monotherapy, followed by statin and ezetimibe combination (3.0%: 18-64 years; 3.8%: ≥65 years). Ten percent or less initiated on high intensity statins. Most common treatment modifications were rechallenging index therapy (25.2%: 18-64 years, 27.0%: ≥65 years), switching (27.5%: 18-64 years, 24.6%: ≥65 years), and permanent discontinuation of any LLT (18.6%: 18-64 years, 21.0%: ≥65 years). Only 10% of patients in both groups underwent dose escalation. CONCLUSIONS: Real-world evidence indicates that few high-risk patients initiate therapy with high-intensity statins. More than 50% of patients underwent a rechallenge or switching. Despite high CVD risk profile, approximately 20% of patients permanently discontinued any LLT. Key limitations: Pharmacy claims do not provide information on whether patients who had a pharmacy fill actually took the medication as prescribed. It is unknown whether rechallenge was a simple delay in filling a prescription or an actual rechallenge of their index therapy. Reasons for treatment discontinuations or modifications were unavailable in claims data.

Longitudinal treatment patterns among US patients with atherosclerotic cardiovascular disease or familial hypercholesterolemia initiating lipid-lowering pharmacotherapy.

BACKGROUND: The most recent American College of Cardiology-American Heart Association guidelines recommend high-dose statin therapy for most patients with confirmed atherosclerotic cardiovascular disease (ASCVD) and patients with high cardiovascular risk. There is limited information regarding long-term treatment patterns among these patients. OBJECTIVE: To examine longitudinal treatment modifications in patients with ASCVD or familial hypercholesterolemia (FH). METHODS: This retrospective analysis of administrative claims data identified patients initiating statin or ezetimibe therapy between January 1, 2007, and December 31, 2012, who had evidence of ASCVD or FH. Patients were followed for up to 3 years and up to 4 treatment episodes. After initial treatment, subsequent treatment episodes began on the date of a treatment modification, which included discontinuation, statin dose change, switching, and augmentation. RESULTS: A total of 92,621 patients (mean age 64.7 years, 57.3% male) were identified; 91,740 had ASCVD, 937 had FH (56 had both). Most ASCVD (89.6%) and FH (85.8%) patients initiated on statin monotherapy. The most common treatment modification in the first treatment episode was discontinuation (ASCVD: 42.0%; FH: 58.4%); among patients who discontinued, most reinitiated therapy (70.5% of ASCVD, 76.8% of FH). Most ASCVD (68.2%) and FH (71.1%) patients initiated on moderate-dose statins; statin dose increase occurred in 10.3% of ASCVD and 18.5% of FH patients in the first episode. CONCLUSION: Among patients with high cardiovascular risk, most initiated on moderate-dose statins with infrequent uptitration. In light of the recent American College of Cardiology-American Heart Association guidelines, statin initiation practices will need to change to ensure appropriate therapy for high-risk patients.

Productivity losses associated with cardiovascular disease: a systematic review.

INTRODUCTION: People with cardiovascular disease (CVD) often require time off work to recover from illness or surgery; for example, following a myocardial infarction (MI) or stroke. These individuals incur income losses, work-related productivity is reduced for employers, and output is reduced for the wider economy. Productivity impacts to the economy also arise due to CVD-related mortality. Areas covered: A systematic literature review was conducted to identify and collate studies that report the magnitude of work-related productivity losses associated with CVD generally or specific cardiovascular (CV) events or conditions (coronary heart disease, MI, stroke, transient ischemic attack, angina, heart failure, peripheral artery disease, coronary revascularization). The search was conducted using Medline, Embase, the Cochrane Library, and Google to find studies published from January 2004 to January 2015. In total, 60 studies were identified, including 20 studies conducted in the USA, 25 studies conducted in Europe, and 18 studies conducted in other countries (three studies were conducted in multiple regions). The studies differed by the scope of losses assessed (absenteeism, presenteeism, early retirement, premature mortality) and CVD conditions/events included. Studies reported either average patient or population losses, and generally used a human capital rather than friction cost method. Outcomes were standardized and adjusted to 2015 US dollars where possible. Expert commentary: The review demonstrates that CVD imposes substantial morbidity- and mortality-related productivity costs. The studies identified in the review may be used to inform and populate societal economic evaluations in CVD, with the most appropriate source study being that most closely matching the context of the evaluation.

A Retrospective Study to Examine Healthcare Costs Related to Cardiovascular Events in Individuals with Hyperlipidemia.

INTRODUCTION: Few studies have demonstrated the cost burden of cardiovascular events (CVEs) among patients with hyperlipidemia. The primary objective of this study was to determine the mean costs associated with CVEs among patients with hyperlipidemia by follow-up time period. Secondary objectives of this study included characterizing costs by CVE type and coronary heart disease (CHD) risk. METHODS: This retrospective cohort study used longitudinal claims to calculate payer costs according to CHD risk level and type of CVE, during several follow-up periods (acute and short-term, comprising year 1; plus years 2 and 3). RESULTS: There were 193,385 patients with hyperlipidemia with a CVE. Costs in the acute (30-day) period were highest ($22,404) driven by inpatient care (77%). Costs remained high ($15,133 in year 3) with ambulatory care (from 14% in acute to 37% in year 3) and pharmaceutical costs (from 2% in acute to 24% in year 3) representing a greater proportion. After second and third CVEs, acute costs were lower than for the first CVE. But in the post-acute periods, costs were higher after second and third CVEs than after first CVEs. Acute costs varied considerably by type of CVE ($9149 for transient ischemic attack to $54,251 for coronary artery bypass graft; P < 0.001), but post-acute costs were more similar across types. Costs differed by baseline CHD risk for all follow-up periods (P < 0.001), but less than by CVE type. As expected, patients without CVEs had significantly lower costs. CONCLUSION: Among patients with hyperlipidemia, the economic burden of CVEs is substantial up to 3 years after a CVE. Costs remain high after subsequent CVEs and actually increase for non-inpatient utilization. FUNDING: Amgen Inc.

Osteoporosis Diagnosis and Management in Long-Term Care Facility.

BACKGROUND: Contemporary estimates of the prevalence of diagnosed osteoporosis among long-term care facility residents are limited. METHODS: This chart review collected data between April 1, 2012 and August 31, 2013 for adult (age ≥ 30 years) residents of 11 long-term care facilities affiliated with the Louisiana State University Health Sciences Center in the New Orleans metropolitan area. Data (demographics; comorbidities; osteoporosis diagnosis, risk factors, diagnostic assessments, treatments; fracture history; fall risk; activities of daily living) were summarized. Data for residents with and without diagnosed osteoporosis were compared using χ tests and t tests. RESULTS: The study included 746 residents (69% women, mean [SD] age: 76.3 [13.9] years, median length of stay approximately 18.5 months). An osteoporosis diagnosis was recorded for 132 residents (18%), 30% of whom received a pharmacologic osteoporosis therapy. Fewer than 2% of residents had bone mineral density assessments; 10% had previous fracture. Calcium and vitamin D use was more prevalent in residents with diagnosed osteoporosis compared with other residents (calcium: 49% versus 12%, vitamin D: 52% versus 28%; both P < 0.001). Over half (304/545) of assessed residents had a high fall risk. Activities of daily living were similarly limited regardless of osteoporosis status. CONCLUSIONS: The prevalence of diagnosed osteoporosis was higher than previously reported for long-term care residents, but lower than epidemiologic estimates of osteoporosis prevalence for the noninstitutional U.S. POPULATION: In our sample, osteoporosis diagnostic testing was rare and treatment rates were low. Our results suggest that osteoporosis may be underdiagnosed and undertreated in long-term care settings.

Hemoglobin stability and patient compliance with darbepoetin alfa in peritoneal dialysis patients after the implementation of the prospective payment system.

PURPOSE: Since the Centers for Medicare & Medicaid Services implemented the End-Stage Renal Disease Prospective Payment System, dialysis providers have increasingly focused on balancing resource utilization and quality outcomes for the treatment of anemia in patients undergoing peritoneal dialysis. Limited data exist regarding anemia management outcomes for these patients in US-based dialysis centers after the implementation of the new payment system. METHODS: This was a retrospective, observational, cohort study of stable PD patients with end-stage renal disease who received darbepoetin alfa for anemia management over a 15-month period (April 1, 2011-June 29, 2012). The medication was administered by staff in the home-training unit instead of being self-administered at home. The primary end point was mean quarterly hemoglobin (Hb) levels. Variability in Hb levels was assessed over the 5 quarters by using repeated measures ANOVA to test for differences in the observed mean SDs. FINDINGS: In the 139 adult patients on stable peritoneal dialysis and meeting the eligibility criteria, mean (SD) Hb level by quarter was 10.8 (1.2) g/dL in quarters 2 and 3 of 2011, 10.5 (1.1) g/dL in quarter 4 of 2011, and 10.4 (1.1) g/dL in quarters 1 and 2 of 2012. Hb levels were stable (mean SDs, 0.58-0.72) over the 5 quarters of the study. Patient compliance with attendance for all scheduled home training unit visits was 84%. IMPLICATIONS: PD patients who underwent darbepoetin alfa administration and twice-monthly laboratory testing in the home-training unit had stable Hb levels. Despite more frequent center visits compared with a home-administered approach, patient compliance was high.

Red blood cell (RBC) transfusion rates among US chronic dialysis patients during changes to Medicare end-stage renal disease (ESRD) reimbursement systems and erythropoiesis stimulating agent (ESA) labels.

BACKGROUND: Several major ESRD-related regulatory and reimbursement changes were introduced in the United States in 2011. In several large, national datasets, these changes have been associated with decreases in erythropoiesis stimulating agent (ESA) utilization and hemoglobin concentrations in the ESRD population, as well as an increase in the use of red blood cell (RBC) transfusions in this population. Our objective was to examine the use of RBC transfusion before and after the regulatory and reimbursement changes implemented in 2011 in a prevalent population of chronic dialysis patients in a large national claims database. METHODS: Patients in the Truven Health MarketScan Commercial and Medicare Databases with evidence of chronic dialysis were selected for the study. The proportion of chronic dialysis patients who received any RBC transfusion and RBC transfusion event rates per 100 patient-months were calculated in each month from January 1, 2007 to March 31, 2012. The results were analyzed overall and stratified by primary health insurance payer (commercial payer or Medicare). RESULTS: Overall, the percent of chronic dialysis patients with RBC transfusion and RBC transfusion event rates per 100 patient-months increased between January 2007 and March 2012. When stratified by primary health insurance payer, it appears that the increase was driven by the primary Medicare insurance population. While the percent of patients with RBC transfusion and RBC transfusion event rates did not increase in the commercially insured population between 2007 and 2012 they did increase in the primary Medicare insurance population; the majority of the increase occurred in 2011 during the same time frame as the ESRD-related regulatory and reimbursement changes. CONCLUSIONS: The regulatory and reimbursement changes implemented in 2011 may have contributed to an increase in the use of RBC transfusions in chronic dialysis patients in the MarketScan dataset who were covered by Medicare plus Medicare supplemental insurance.

Evaluation of the consumer assessment of healthcare providers and systems in-center hemodialysis survey.

BACKGROUND AND OBJECTIVES: The US Centers for Medicare and Medicaid Services (CMS) End Stage Renal Disease Prospective Payment System and Quality Incentive Program requires that dialysis centers meet predefined criteria for quality of patient care to ensure future funding. The CMS selected the Consumer Assessment of Healthcare Providers and Systems In-Center Hemodialysis (CAHPS-ICH) survey for the assessment of patient experience of care. This analysis evaluated the psychometric properties of the CAHPS-ICH survey in a sample of hemodialysis patients. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Data were drawn from the Adelphi CKD Disease Specific Program (a retrospective, cross-sectional survey of nephrologists and patients). Selected United States-based nephrologists treating patients receiving hemodialysis completed patient record forms and provided information on their dialysis center. Patients (n=404) completed the CAHPS-ICH survey (comprising 58 questions) providing six scores for the assessment of patient experience of care. CAHPS-ICH item-scale convergence, discrimination, and reliability were evaluated for multi-item scales. Floor and ceiling effects were estimated for all six scores. Patient (demographics, dialysis history, vascular access method) and facility characteristics (size, ratio of patients-to-physicians, nurses, and technicians) associated with the CAHPS-ICH scores were also evaluated. RESULTS: Item-scale correlations and internal consistency reliability estimates provided support for the nephrologists' communication (range, 0.16-0.71; α=0.81) and quality of care (range, 0.16-0.76; α=0.90) composites. However, the patient information composite had low internal consistency reliability (α=0.55). Provider-to-patient ratios (range, 2.37 for facilities with >36 patients per physician to 2.8 for those with <8 patients per physician) and time spent in the waiting room (3.44 for >15 minutes of waiting time to 3.75 for 5 to <10 minutes) were characteristics most consistently related to patients' perceptions of dialysis care. CONCLUSIONS: CAHPS-ICH is a potentially valuable and informative tool for the evaluation of patients' experiences with dialysis care. Additional studies are needed to estimate clinically meaningful differences between care providers.

The effect of prophylaxis on pediatric HIV costs.

The objective of this study was to determine and compare the cost to treat HIV(+) and HIV(-) pediatric patients both before and after HIV prophylaxis became the standard of care. Retrospective chart review of a pediatric HIV/AIDS specialty clinic's medical charts was conducted for clinical and healthcare utilization data on 125 children diagnosed from 1986 to 2007. Mean HIV-related costs were compared using bootstrapped t-tests for children born in the pre-prophylaxis (1979-1993) and prophylaxis eras (1994-2007). Patients were also stratified into two categories based on death during the follow-up period. Lastly, national cost-savings were estimated using mean costs, national number of at-risk births, and national perinatal HIV transmission rates in each era. For HIV(+) children, mean annual per patient treatment cost was $15,067 (95% CI: $10,169-$19,965) in the pre-prophylaxis era (n = 40) and $14,959 (95% CI: $9140-$20,779) in the prophylaxis era (n = 14); difference not statistically significant (p > 0.05). For HIV(-) children, mean annual per patient treatment cost was $204 (95% CI: $219-$627) for the pre-prophylaxis era (n = 2) and $427 (95% CI: $277-$579) for the prophylaxis era (n = 69); difference statistically significant (p < 0.05). A projected cost-savings of $16-23 million annually in the USA was observed due to the adoption of prophylaxis treatment guidelines in pediatric HIV care. The prophylaxis era of pediatric HIV treatment has been successful in decreasing perinatal HIV transmission and mortality, as reflected by clinical trials and national cost-savings data, and emphasizes the value of the rapid adoption of evidence-based practice guidelines.

Health care costs for patients with cancer at the end of life.

PURPOSE: With rising health care costs in the United States, clearly defined end-of-life (EOL) cancer costs are needed to help health administrators proactively manage this important care. Our objective was to examine EOL health care resource costs among oncology patients in a US commercial insurance population. METHODS: A retrospective claims database affiliated with OptumInsight was analyzed. Included patients had: a medical claim with cancer diagnosis between July 1, 2002, and December 31, 2009; death on or before December 31, 2009; continuous enrollment with medical/pharmacy benefits from diagnosis until death; ≥ 180 follow-up days; and active cancer in the last 6 months before death (MBD). Death was captured from facility discharge codes or Social Security Administration death files. Costs were determined by summing paid amounts on all services utilized within the last 6 MBD: cancer-related inpatient (IP) stays, cancer- related hospice care, and cancer-related outpatient (OP) services (ie, chemotherapy, erythropoiesis-stimulating agents, granulocyte colony-stimulating factors, radiation, cancer-related office or emergency room visits, cancer-related hospital OP procedures, and other services with cancer diagnosis). RESULTS: A total of 28,530 patients met inclusion criteria. Mean total cancer-related costs in the last 6 MBD were $74,212 (standard deviation, $112,740), comprising IP costs of $40,702 (55%), OP costs of $30,254 (41%), and hospice costs of $3,256 (4%). OP costs decreased from $6,021 in the sixth MBD to $2,238 in the last MBD, whereas IP care costs increased from $1,785 to $20,559. Hospice utilization increased from 0.7% in the sixth MBD to 35.6% in the last MBD. CONCLUSION: Oncology costs increase in the last 6 MBD largely because of increased IP costs, whereas OP costs decrease.
