Outcomes Following Initiation of Triple Therapy with Fluticasone Furoate/Umeclidinium/Vilanterol versus Multiple-Inhaler Triple Therapy Among Medicare Advantage with Part D Beneficiaries and Those Commercially Enrolled for Health Care Insurance in the United States.

Purpose: Patients with chronic obstructive pulmonary disease (COPD) have been shown to benefit from triple therapy commonly delivered by multiple-inhaler triple therapy (MITT); however, the complexity of MITT regimens may decrease patient adherence. Fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI), a once-daily single-inhaler triple therapy (SITT), became available in the United States (US) in 2017, but real-world data comparing outcomes for SITT versus MITT are currently limited. This study compared outcomes among patients with COPD initiating MITT versus SITT with FF/UMEC/VI who were either Medicare Advantage with Part D (MAPD) beneficiaries or commercial enrollees in the US. Methods: Retrospective study using administrative claims data from the Optum Research Database for patients with COPD who initiated FF/UMEC/VI or MITT between September 1, 2017, and March 31, 2019 (index date: first pharmacy claim for FF/UMEC/VI cohort; earliest day of ≥30 consecutive days-long period of overlap in the day's supply of all triple therapy components for MITT cohort). COPD exacerbations, adherence to triple therapy, and all-cause and COPD-related health care resource utilization (HCRU) and costs were compared between FF/UMEC/VI and MITT initiators. Results: In total, 4659 FF/UMEC/VI initiators and 9845 MITT initiators for the MAPD population, and 821 FF/UMEC/VI initiators and 1893 MITT initiators for the commercial population were included in the study. MAPD beneficiaries initiating FF/UMEC/VI had a significantly lower annual rate of severe exacerbations compared to MITT initiators (0.26 vs 0.29; p=0.014). They also had a significantly higher mean adherence (proportion of days covered) (0.51 vs 0.37; p<0.001) and significantly lower all-cause and COPD-related inpatient stays compared to MITT initiators ([32.02% vs 34.27%; p=0.017], [16.09% vs 17.72%; p=0.037]). Trends were similar among the commercial population, but the results were not statistically significant. Conclusion: FF/UMEC/VI initiators had significantly fewer severe exacerbations, higher triple therapy adherence, and lower HCRU costs compared to MITT initiators for MAPD beneficiaries.

Burden of Illness Among Patients with Psychosis due to Dementia with Lewy Bodies and Other Dementias.

Limited research is available on the real-world experiences of patients with dementia with Lewy bodies (DLB). This study evaluated clinical events, healthcare utilization, and healthcare costs of patients with DLB vs other dementia types with psychosis (ODP). Study patients included commercial and Medicare Advantage with Part D enrollees aged ≥40 years with evidence of DLB and ODP from 6/01/2015‒5/31/2019. Compared with patients with ODP, more patients with DLB had clinical events including anticholinergic effects, neurologic effects, and cognitive decline. Patients with DLB used more healthcare resources with greater dementia-related office and outpatient visits and psychosis-related inpatient stays and office, outpatient, and emergency visits compared with their ODP patient counterparts. Patients with DLB also incurred higher healthcare costs for all-cause and dementia-related office visits and pharmacy fills, and psychosis-related total costs. Understanding the clinical and economic impact of DLB and ODP is important to improve care for patients with dementia.

COPD Exacerbations, Costs, and Health Care Resource Utilization Before and After Initiation of Fluticasone Furoate/Umeclidinium/Vilanterol in Routine Care in the USA.

Purpose: To examine the impact of initiating fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) in a single device on chronic obstructive pulmonary disease (COPD) exacerbations, COPD exacerbation-related costs, and all-cause and COPD-related healthcare resource utilization (HCRU) and costs in patients with COPD. Methods: Retrospective database analysis of patients with COPD aged ≥40 years who initiated FF/UMEC/VI between September 1, 2017, and December 31, 2018 (index date: first pharmacy claim for FF/UMEC/VI), following evidence of multiple-inhaler triple therapy (MITT) (≥30 consecutive days) in the year prior to index. COPD exacerbations, COPD exacerbation-related costs, and all-cause and COPD-related HCRU and costs were compared between the baseline period (12 months prior to and including index) and follow-up period (12 months following index). Results: Data from 912 patients (mean [SD] age: 71.2 [8.1], 51.2% female) were included in the analyses. Among the overall cohort, mean count of total COPD exacerbations (moderate or severe) per patient was statistically significantly lower in the follow-up period compared to baseline (1.2 vs 1.4, p=0.001). The proportion of patients with ≥1 COPD exacerbation (moderate or severe) was also statistically significantly lower in the follow-up period compared to baseline (56.4% vs 62.4%, p=0.001). All-cause and COPD-related HCRU were similar during follow-up compared to baseline, although the proportion of patients with COPD-related ambulatory visits was lower during follow-up (p<0.001). COPD-related office visit costs, emergency room visit costs, and pharmacy costs were statistically significantly lower during follow-up compared to baseline (p<0.001; p=0.019; p<0.001, respectively). Conclusion: In a real-world setting, patients on MITT who subsequently initiated FF/UMEC/VI in a single device had significant reductions in the rate of COPD exacerbations (moderate or severe). Switching to FF/UMEC/VI also resulted in improvements in some HCRU and cost outcomes. These data support the use of FF/UMEC/VI among patients at high risk of exacerbation to reduce future risk and improve outcomes.

Health Care Resource Utilization and Costs Associated with Disease Progression in Ovarian Cancer.

INTRODUCTION: Ovarian cancer (OC) is one of the leading causes of cancer mortality among women in the United States. With the approval of first-line maintenance therapies, patients with OC experienced prolonged first-line progression-free survival. While the literature addresses some costs associated with OC, further research is needed on the costs of progression that are potentially deferred or prevented by early maintenance. The objective of this study was to capture the health care resource utilization and costs of patients with advanced OC who never received poly(ADP ribose) polymerase (PARP) inhibitor maintenance. METHODS: We conducted a descriptive retrospective analysis of treatment patterns and the consequences of progression through several lines of therapy (LOTs) in patients with OC, using claims from commercial and Medicare Advantage health plan members in the United States from the Optum Research Database between January 1, 2010, and April 30, 2019. Patients were required to have an index OC diagnosis (≥ 2 non-diagnostic claims). We examined up to 4 LOTs and the time between treatments. RESULTS: A total of 5498 women met the eligibility criteria. As the number of LOTs increased, the median duration of each line decreased from 137 days in LOT1 to 94 days in LOT4, and the time between lines also decreased from 245 to 0 days. Ambulatory care visits were a major driver of health care resource utilization, with a median of about 6 monthly visits during active treatment. The mean total monthly health care costs for patients with at least 2 LOTs were US$8588 (SD: $8533) before LOT2 and increased to $15,358 (SD: $21,460) during or after LOT2. CONCLUSIONS: Prolonging progression-free survival after first-line treatment in patients with OC may provide the opportunity to delay or prevent later treatment, the financial toxicity felt by patients, and the economic burden to the health care system associated with progression.

Ovarian cancer is a complex disease in which > 70% of patients are diagnosed with advanced disease, and one of the leading causes of cancer mortality among women in the United States. A variety of maintenance therapy options, including bevacizumab, PARP inhibitors, and PARP plus bevacizumab combination therapies, have demonstrated improvements in progression-free survival. By delaying disease progression after completion of first-line therapy, a simultaneous decrease in post-progression health care costs may be seen. The objective of this study was to capture the health care resource utilization and costs of patients with advanced ovarian cancer who did not receive a PARP inhibitor at any time in their treatmentIn patients never receiving a PARP inhibitor, this study documented substantial health care resource usage and costs associated with progression beyond the first line of treatment (surgery and/or chemotherapy) in ovarian cancer. These were largely driven by the number of ambulatory care visits. When these visits are combined with emergency department visits and inpatient stays, high costs are incurred by both patients and third-party payersProlonging progression-free survival after first-line treatment in patients with ovarian cancer may delay or prevent the need for later treatment, the financial burden felt by patients, and the economic burden to the health care system associated with subsequent disease progressions.

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.

Economic impact of applying the AASLD-IDSA simplified treatment algorithm on the real-world management of hepatitis C.

BACKGROUND: The American Association for the Study of Liver Diseases (AASLD) and the Infectious Diseases Society of America (IDSA) recommended in May 2019 that patients with hepatitis C virus (HCV) could be assessed for treatment initiation with a simplified treatment algorithm. This approach uses standard blood and fibrosis tests, rather than genotype testing, to guide the initiation of pan-genotypic direct-acting antiviral agents (DAAs) sofosbuvir/velpatasvir (SOF/VEL) or glecaprevir/pibrentasvir (GLE/PIB) treatment. OBJECTIVE: To compare health care resource utilization (HCRU) and costs for patients who initiated treatment via the simplified vs nonsimplified algorithm (genotype testing). METHODS: We identified adults with commercial and Medicare Advantage coverage who were diagnosed with HCV who initiated SOF/VEL or GLE/PIB from July 1, 2016, through August 31, 2019, in a nationally representative US administrative claims database. The index date was defined as the first pharmacy SOF/VEL or GLE/PIB fill date. Continuous enrollment 12 months before and ≥6 months after index date was required. Patients with claims for hepatitis B, HIV, decompensated liver, or prior DAAs were excluded. Patients were propensity score-matched (1:1) and grouped as "simplified" or "nonsimplified." HCV-related HCRU and costs were compared for the post-matched groups. RESULTS: 3,539 HCV patients were included, and 16.6% initiated SOF/VEL or GLE/PIB via the simplified algorithm. Pre-matched treatments were SOF/VEL (52.8%) and GLE/PIB (47.2%). More than half (55.7%) of SOF/VEL and 44.3% of GLE/PIB patients started treatment via the simplified algorithm. HCV patients initiating via the simplified algorithm were more likely to be male (65.1% vs 60.6%; P = 0.041), commercially insured (53.3% vs 46.5%; P = 0.003), and in the Midwest (25.7% vs 19.3%; P < 0.001) vs nonsimplified patients. The nonsimplified group had more liver disease (52.1% vs 46.9%; P = 0.019), metabolic disorders (45.8% vs 39.2%; P = 0.003), and dyslipidemia (39.9% vs 35.4%; P = 0.041) vs the simplified group. Of the index prescriptions, 58.9% were written by gastroenterology or infectious disease specialists, and 68.1% (simplified) vs 75.4% (nonsimplified) had a specialist visit within 90 days prior to index DAA fill (P < 0.001). Matching resulted in 584 well-matched patients in each group. At post-match baseline, the simplified treatment group had significantly lower median (interquartile range [IQR]) HCV-related medical health care costs vs the matched nonsimplified group: $373 ($201-$684) vs $727 ($456-$1,185; P < 0.001). Median noninpatient/emergency department health plan-paid costs were also significantly lower in the simplified cohort ($257 vs $504; P < 0.001). During follow-up, medical HCV-related health care costs were similar across the groups. CONCLUSIONS: This study compared economic outcomes of HCV treatment initiation via the simplified and nonsimplified algorithms. The simplified approach resulted in lower use of health care resources, greater cost savings, and greater ability of patients to access care from both specialist and nonspecialist providers. While additional studies are needed, these early findings suggest a feasible path for simplified HCV treatment in real-world managed care settings.

Increasing prevalence of metastatic castration-resistant prostate cancer in a managed care population in the United States.

PURPOSE: Numerous treatment breakthroughs for patients with metastatic castration-resistant prostate cancer (mCRPC) have been demonstrated in clinical trials in the past 15 years. However, real-world evidence on the changing epidemiology and longevity of this population has not been demonstrated. This study assessed prevalence trends for mCRPC over eight years in a large managed care population. METHODS: In a claims database, adult male patients were included with ≥ 1 claim for prostate cancer, pharmacologic/surgical castration, and metastatic disease during the identification period. The index mCRPC date was the first metastatic claim; six months of continuous enrollment before and after was required. Patients with metastatic disease at baseline were excluded. Patients were followed until death, end of study, or disenrollment, whichever was earliest. Total, mCRPC per-prostate cancer, and age-specific prevalence rates were calculated cross-sectionally for each year under study (2010-2017). RESULTS: Of 343,089 patients identified with a claim for prostate cancer, 3690 mCRPC cases (1.1%) were identified. Incidence (new cases per year) remained relatively constant over the study period while prevalence of mCRPC (total cases per year) increased. mCRPC prevalence increased with increasing age. Total and mCRPC per-prostate cancer prevalence rates increased in monotonic, year-over-year trends from 2010 to 2017, while incidence (new cases per year) of mCRPC remained relatively stable. CONCLUSION: This study found increasing prevalence of mCRPC in an insured patient population during the 8-year period, coupled with stable incidence, validating that patients with the disease are living longer. With the addition of androgen receptor-directed therapies and poly(ADP-ribose) polymerase inhibitors in recent years, this trend will likely continue.

Real-World Costs of Adverse Events in First-Line Treatment of Metastatic Non-Small Cell Lung Cancer.

BACKGROUND: Non-small cell lung cancer (NSCLC) is the most common form of lung cancer in the United States. Immunotherapies and cytotoxic chemotherapies used to treat advanced NSCLC carry a substantial risk of adverse events (AEs), but real-world data on the incidence and costs associated with the unique AE profiles of these treatments are sparse. OBJECTIVE: To examine the AE incidence and costs among patients initiating non-driver mutation-targeted first-line therapy for metastatic NSCLC (mNSCLC) in clinical practice. METHODS: This was a retrospective administrative claims study conducted among commercial and Medicare Advantage health plan members who initiated first-line, nontargeted systemic anti-NSCLC therapy between January 1, 2008, and February 28, 2018. Patients were assigned to mutually exclusive treatment cohorts (cytotoxic chemotherapy [CHEM], immuno-oncology agents [IO], or immuno-oncology + cytotoxic chemotherapy [IO-CHEM]) and were observed from the index date (start of first-line therapy) through the earliest of health plan disenrollment, death, or March 31, 2018. AE incidence rates and associated health care costs were measured from the index date through the earliest of the start of a new therapy, 180 days after the end of first-line therapy, or the end of the study period. The factors influencing whether patients incurred high AE-related health care costs were assessed using multivariable models adjusted for patient demographic and clinical characteristics. RESULTS: The final study population (mean [SD] age 68.6 [9.5] years, 53.9% male) included 8,818 in the CHEM cohort, 482 in the IO cohort, and 412 in the IO-CHEM cohort. Overall, 74.4% had at least 1 AE during follow-up. The AE incidence rate was lowest for the IO cohort, with incidence rate ratios (95% CI) of 1.4 (1.3-1.6) for the CHEM cohort and 1.4 (1.2-1.6) for the IO-CHEM cohort. Mean AE-related costs were lowest for the IO cohort ($16,319) and highest for the CHEM cohort ($23,009; P < 0.001). In the multivariable analysis, the odds of incurring any AE costs were similar for the IO and IO-CHEM cohorts compared with the CHEM cohort (OR = 0.82; P = 0.135 and OR = 0.98; P = 0.888, respectively). Among patients who incurred AE costs, those in the IO cohort were less likely than those in the CHEM cohort to have high costs (OR = 0.60; P = 0.030); the difference between the IO-CHEM and CHEM cohorts was not statistically significant. CONCLUSIONS: Among real-world patients initiating nontargeted first-line therapy for mNSCLC, those receiving immunotherapy experienced fewer AEs and had lower total AE-related costs than those treated with cytotoxic chemotherapy. Immunotherapy-treated patients were no more likely than chemotherapy-treated patients to incur AE-related costs and were less likely to have high AE costs if they incurred any at all. These findings indicate that immunotherapy-related AEs are not a differentiating factor in cost of care for this patient population in clinical practice.

Ethnicity related differences in the survival of young breast carcinoma patients.

BACKGROUND: African-American women face an increased risk of early-onset breast carcinoma compared to white American women, and breast carcinoma has been reported to be particularly aggressive in premenopausal women. METHODS: Surveillance, Epidemiology, and End Results Program data were analyzed for 507 African-American and 1378 white patients from Detroit diagnosed with breast carcinoma under the age of 40 between 1990 and 1999. RESULTS: The proportion of in situ disease detected in African-American patients between 1995 and 1999 nearly doubled compared to the 1990-1994 interval (11.3% compared to 6.4%) but was consistently lower than the proportion of in situ disease seen in white patients for the same intervals (15.7% and 16.4% respectively). Evaluation of patients with invasive disease revealed that African-American patients had larger mean tumor size (3.4 cm versus 2.6 cm; P < 0.001), lower rates of localized disease (42.4% versus 52.1%; P < 0.001), higher rates of estrogen receptor negativity (61.9% versus 44.4%; P < 0.001), and higher proportions of medullary tumors (5.8% versus 3.3%; P = 0.021). Cox proportional hazards survival analysis adjusted for age, tumor size, nodal status, hormone receptor status, and histology showed higher mortality rates for African-American patients at all disease stages. Relative risk of death for African-American patients was 1.94 in patients with localized disease (95% confidence interval [CI], 1.23-3.05), 1.58 for regional disease (95% CI = 1.18-2.11), and 2.32 for distant disease (95% CI = 1.15-4.69). CONCLUSIONS: These findings show that young African-American breast carcinoma patients face an increased mortality risk. Additional studies evaluating risk and treatment response in this subset of patients are warranted.

Complications from treatment for prostate carcinoma among men in the Detroit area.

BACKGROUND: Aggressive treatment of early stage prostate carcinoma (PC) is limited primarily to two modalities: radical prostatectomy (RP) and external beam radiation therapy (RT). The authors conducted a population-based study of Detroit area men with localized PC to determine the outcome of bowel, urinary, and sexual function after aggressive treatment. METHODS: Men with PC were identified through the Metropolitan Detroit Cancer Surveillance System, a member of the National Cancer Institute Surveillance, Epidemiology, and End Results Program. Patients participated in interviews about their pretreatment bowel, urinary, and sexual function approximately 9 months after treatment. The same men were asked identical questions about their function an average of 2 years after treatment. Treatment outcomes were compared for men who underwent RP and men who received RT. RESULTS: Of 501 men, 398 (79.4%) participated in both interviews, 304 of whom (76.4%) had localized PC and had been treated at least 1 year previously (median, 688 days). One hundred thirty men underwent RP, and 115 men received RT. The proportion of men in the RP group who reported an increase in incontinence symptoms was significant (53.8% compared with 19.2% in the RT group; P < 0.001). Men in the RT group reported increased loose stools between the pretreatment and post-treatment interviews (5.2% vs. 29.6%; P < 0.001). Men in both the RT group and the RP group reported increases in impotence from 40% to > 75% (P < 0.001 for both). Men in the RT group were 3.6 times more likely to have bowel incontinence compared with men in the RP group (odds ratio [OR], 3.61; 95% confidence interval [95% CI], 1.54-8.47). Urinary incontinence (OR, 2.87; 95% CI, 1.52-5.44) and erection difficulty (OR, 3.98; 95% CI, 1.35-11.70) were more likely among men in the RP group. CONCLUSIONS: Although patients may have recalled their baseline function as better than it was, the current results are consistent with other population-based studies of treatment outcomes among men with localized PC. They indicate that the side effects associated with treatment are greater than those based on case series. Physicians and patients should be aware of these population-based outcomes and should use them as part of the decision-making process regarding the treatment options for men with PC.

Put prevention into practice (PPIP): evaluating PPIP in two family practice residency sites.

BACKGROUND AND OBJECTIVES: The Put Prevention Into Practice (PPIP) office system is a set of office tools designed to address physician, patient, and system barriers to the provision of clinical preventive services. This study evaluated the effect of using PPIP on the delivery of clinical preventive services at two family practice residency sites. METHODS: After a careful planning process at each clinic, a 1-year trial was conducted with implementation of PPIP at two residency sites compared to two control residency sites. The subjects included adults age 19 and older Data were collected via chart extraction on 300 randomly selected patients per clinic for the following three outcomes: health risk factor assessment (for limited physical activity, poor nutrition habits, and tobacco use), health promotion/counseling (for nutrition, physical activity, and tobacco use), and screening rates (clinical breast exam, cholesterol, fecal occult blood test, mammography, and Pap smear). RESULTS: Only inconsistent or sporadic differences in risk factor assessment, health promotion counseling, and screening were seen when comparing implementation and control sites. CONCLUSIONS: PPIP had little effect on the delivery of clinical preventive services. Future research should include a careful analysis of the users of PPIP and the environments in which they practice.
