Comparison of Healthcare Costs for Women with Treated Versus Untreated Vasomotor Symptoms Due to Menopause.

INTRODUCTION: The study objective was to estimate all-cause healthcare resource utilization (HCRU) and medical and pharmacy costs for women with treated versus untreated vasomotor symptoms (VMS) due to menopause. METHODS: A retrospective study was conducted using US claims data from Optum Research Database (study period: January 1, 2012-February 29, 2020). Women aged 40-63 years with a VMS diagnosis claim and ≥ 12 and ≥ 18 months of continuous enrollment during baseline and follow-up periods, respectively, were included. Women treated for VMS were propensity score matched 1:1 to untreated controls with VMS. Standardized differences (SDIFF) ≥ 10% were considered meaningful. A generalized linear model (gamma distribution, log link, robust standard errors) estimated the total cost of care ratio. Subgroup analyses of on- and off-label treatment costs were conducted. RESULTS: Of 117,582 women diagnosed with VMS, 20.5% initiated VMS treatment and 79.5% had no treatment. Treated women (n = 24,057) were matched to untreated VMS controls. There were no differences in HCRU at follow-up (SDIFF < 10%). Pharmacy ($487 vs $320, SDIFF 28.4%) and total ($1803 vs $1536, SDIFF 12.6%) costs were higher in the treated cohort. Total costs were 7% higher in the treated cohort (total cost ratio 1.07, 95% CI 1.05-1.10, P < 0.001). The on-label treatment pharmacy costs ($546 versus $315, SDIFF 38.6%) were higher in the treated cohort. Off-label treatment had higher medical costs ($1393 versus $1201, SDIFF 10.4%). CONCLUSIONS: Most women with VMS due to menopause were not treated within 6 months following diagnosis. While both on- and off-label treatment increased the total cost of care compared with untreated controls, those increases were modest in magnitude and should not impede treatment for women who report symptom improvement as a result of treatment.

Treatment patterns of galcanezumab versus standard of care preventive migraine medications over 24 months: a US retrospective claims study.

OBJECTIVE: To describe long-term (24-month) treatment patterns of patients initiating galcanezumab versus standard of care (SOC) preventive migraine treatments including anticonvulsants, beta-blockers, antidepressants, and onabotulinumtoxinA using administrative claims data. METHODS: This retrospective cohort study, which used Optum de-identified Market Clarity data, included adults with migraine with ≥1 claim for galcanezumab or SOC preventive migraine therapy (September 1, 2018 - March 31, 2020) and continuous database enrollment for 12 months before (baseline) and 24 months after (follow-up) the index date (date of first claim). Baseline patient demographics, clinical characteristics, and treatment patterns were analyzed after 24-month follow-up, including adherence (measured as the proportion of days covered [PDC]), persistence, discontinuation (≥60-day gap), restart, and treatment switch. Propensity score matching (1:1) was used to balance the galcanezumab and SOC cohorts. RESULTS: The study included 2307 matched patient pairs with 24-month follow-up. The mean age across cohorts was 44.5 years (females: ∼87%). Patients in the galcanezumab versus SOC cohort demonstrated greater treatment adherence (PDC: 48% vs. 38%), with more patients considered adherent (PDC ≥80%: 26.6% vs. 20.7%) and persistent (322.1 vs. 236.4 d) (all p < .001). After 24-month follow-up, fewer galcanezumab-treated patients had discontinued compared with SOC-treated patients (80.1% vs. 84.7%; p < .001), of which 41.3% and 39.6% switched to a non-index medication, respectively. The most prevalent medication patients switched to in both cohorts was erenumab. Significantly greater proportions of patients who initiated galcanezumab versus SOC medications switched to fremanezumab (p < .001) and onabotulinumtoxinA (p = .016). CONCLUSION: Patients who initiated galcanezumab for migraine prevention had higher treatment adherence and persistence compared with those who initiated SOC medications after 24-month follow-up.

Only few patients (3 − 13%) with migraine, who qualify for preventive treatment, are using them. Conventional preventive treatments have not been developed specifically for migraine treatment, and more than half of the patients stop using them prematurely. Calcitonin gene-related peptide monoclonal antibodies such as galcanezumab, fremanezumab, and erenumab are newer treatments that provide migraine-specific preventive treatment. Prior studies have compared 6- to 12-month migraine medication use by patients starting galcanezumab versus those starting traditional standard of care (SOC) migraine preventive medications. We compared long-term (24-month) migraine medication use in patients starting galcanezumab versus those starting SOC migraine preventive medications to confirm if the results are sustained over a longer period. Over 24 months, patients who used galcanezumab followed the prescribed treatment regimen to a greater extent compared with those who used SOC medications (48% vs. 38%, respectively). Additionally, patients using galcanezumab continued treatment for a longer time compared with those using SOC. Over 24 months, about 85% of patients stopped taking SOC medications, while around 80% of patients stopped taking galcanezumab. Our findings indicate that patients with migraine are more likely to continue using galcanezumab as a preventive treatment for a longer period compared with SOC medications. This study helps identify gaps in the preventive treatment of migraine and provides insights on how they are not being used enough.

Variation in spending associated with primary care practices.

OBJECTIVES: To measure variation in spending and inpatient prices associated with the primary care physician (PCP) practice to which patients are attributed. STUDY DESIGN: Cross-sectional analysis of claims data. METHODS: We used random effect models to estimate case mix-adjusted spending across large PCP practices within 3-digit zip codes. We compare inpatient prices for patients in high-spending practices with those in low-spending practices. RESULTS: The physician practice to which a patient was attributed is associated with significant differences in spending after controlling for patient comorbidities and geography. Patients attributed to practices in the top quartile of total medical expenses have about 30% higher spending than patients attributed to practices in the bottom quartile of adjusted spending in their 3-digit zip code. If patients attributed to practices in the top 2 quartiles had spending equivalent to those in the median practice, total spending would drop by 8%. Price variation accounts for a meaningful amount of the variation, with inpatient prices 17% higher in top-quartile vs bottom-quartile practices. We cannot disaggregate the large variation in utilization into practice patterns and unmeasured case mix (including unmeasured differences in patients' socioeconomic status) vs random health shocks, but correlation in spending patterns across years suggests that some persistent differences in spending patterns exist. CONCLUSIONS: There are meaningful opportunities to reduce spending by changing patient PCP selection, encouraging patients to use lower-priced specialists and hospitals, and eliminating wasteful care. Attention must be paid to the best ways to reap these savings.

Health care resource utilization and disease modifying treatment use in multiple sclerosis patients by age and insurance type.

OBJECTIVE: The objective of this study was to describe and compare health care resource utilization (HCRU) and disease modifying treatment (DMT) use among US adults <65 years with multiple sclerosis (MS), across commercial and Medicare Advantage plans. METHODS: Medical and pharmacy claims data from commercial and Medicare Advantage with Part D (MAPD) plans were extracted for MS patients age 18 - 64 identified between 1 January 2014 and 31 May 2017. Comparisons were made between commercial and MAPD enrollees for all-cause HCRU and DMT use over 1 year, overall and by 5 year age groups. RESULTS: A total of 28,427 MS patients were identified; two-thirds (67%) had commercial coverage. MAPD patients had statistically significantly higher mean counts of all-cause inpatient, emergency room (ER) and ambulatory visits compared to commercial patients. The significant differences were evident in all age groups ≥30 years, except for ER visits in the 40-44 and 60-64 age groups. MAPD patients had statistically significantly lower prevalence of DMT use compared to commercial patients in all age groups starting at ≥35 years. CONCLUSION: MAPD patients had a higher burden of medical HCRU compared to their commercially insured counterparts, most likely due primarily to their more advanced disease state and higher level of MS-related disability. Reasons for lower prevalence of DMT use among MAPD patients may include their more advanced disease state, older age and higher prevalence of comorbid conditions compared with commercially insured patients, as well as more restrictive formularies for MAPD vs. commercial plans. These findings suggest that there may be an opportunity for recently approved DMTs indicated for active secondary progressive MS to fulfill an unmet need for treatment among MS patients <65 years without contraindicated comorbid conditions who are enrolled in MAPD plans. Novel therapies under development to delay progression may help keep MS patients of working age in the work force.

Impact of Endometriosis Diagnostic Delays on Healthcare Resource Utilization and Costs.

INTRODUCTION: Endometriosis symptoms are nonspecific and overlap with other gynecologic and gastrointestinal diseases, leading to long diagnostic delays. The burden of endometriosis has been documented; however, little is known about the impact of diagnostic delays on healthcare costs leading up to diagnoses. The purpose of this study was to examine the economic impact of diagnostic delays on pre-diagnosis healthcare utilization and costs among patients with endometriosis. METHODS: This was a retrospective database study of adult patients with a diagnosis of endometriosis from 1 January 2004 to 31 July 2016. Patients had continuous health plan enrollment 60 months prior to and 12 months following the earliest endometriosis diagnosis and ≥ 1 pre-diagnosis endometriosis symptom (dyspareunia, generalized pelvic pain, abdominal pain, dysmenorrhea, or infertility). Patients were assigned to short (≤ 1 year), intermediate (1-3 years), or long (3-5 years) delay cohorts based on the length of their diagnostic delay (time from first symptom to diagnosis). Healthcare resource utilization and costs were calculated and compared by cohort in the 60-month pre-diagnosis period. RESULTS: A total of 11,793 patients were included in the study, of which 37.7% (4446/11,793), 27.0% (3179/11,793), and 35.3% (4168/11,793) had short, intermediate, and long delays, respectively. Patients with intermediate or long diagnostic delays had consistently more all-cause and endometriosis-related emergency visits and inpatient hospitalizations in the pre-diagnosis period than patients with short delays. Pre-diagnosis all-cause healthcare costs were significantly higher among patients with longer diagnostic delays, averaging $21,489, $30,030, and $34,460 among patients with a short, intermediate, and long delay, respectively (p < 0.001 for all pairwise comparisons). Endometriosis-related costs accounted for 12.5% ($3553/$28,376) of all-cause costs and followed a similar pattern. CONCLUSION: Patients with endometriosis who had longer diagnostic delays had more pre-diagnosis endometriosis-related symptoms and higher pre-diagnosis healthcare utilization and costs compared with patients who were diagnosed earlier after symptom onset, providing evidence in support of earlier diagnosis.

Adherence, persistence, and discontinuation among Hispanic and African American patients with multiple sclerosis treated with fingolimod or glatiramer acetate.

OBJECTIVE: Few studies have examined compliance to disease-modifying therapies (DMTs) for multiple sclerosis (MS) in minority populations. This study compared adherence, discontinuation, and persistence for fingolimod (FTY) and glatiramer acetate (GA) initiators among Hispanic and African American patients with MS. METHODS: This retrospective claims data study examined Hispanic and African American adults with MS who initiated FTY or GA between September 1, 2010 and June 30, 2014. Outcomes (adherence, discontinuation, and persistence) were analyzed descriptively and with multivariable models, comparing FTY and GA cohorts within racial/ethnic groups. Adherence was assessed using medication possession ratio (MPR) and proportion of days covered (PDC). RESULTS: There were 171 patients in the Hispanic group (62 FTY, 109 GA) and 210 in the African American group (71 FTY, 139 GA). A larger proportion of GA initiators than FTY initiators were treatment-naïve; other baseline characteristics were similar between cohorts. Hispanic FTY initiators had greater mean MPR, PDC, and persistence and less discontinuation than GA initiators. African American FTY initiators had greater mean PDC than GA initiators; other outcomes favored FTY but were not statistically significant. Multivariable analysis results were consistent with the unadjusted results, but differences between treatment cohorts were not statistically significant. CONCLUSIONS: Hispanic and African American patients with MS who initiated FTY had higher adherence than those who initiated GA, similar to the general MS population. These findings suggest that adherence should be considered in DMT selection, and racial/ethnic variations in MS disease course may not be primarily attributable to differences in DMT compliance.

Decomposition of moral hazard.

This study seeks to simulate the portion of moral hazard that is due to the income transfer contained in the coinsurance price reduction. Healthcare spending of uninsured individuals from the MEPS with a priority health condition is compared with the predicted counterfactual spending of those same individuals if they were insured with either (1) a conventional policy that paid off with a coinsurance rate or (2) a contingent claims policy that paid off by a lump sum payment upon becoming ill. The lump sum payment is set to be equal to the insurer's predicted spending under the coinsurance policy. The proportion of moral hazard that is efficient is calculated as the proportion of total moral hazard that is generated by this lump sum payment. We find that the efficient proportion of moral hazard varies from disease to disease, but is the highest for those with diabetes and cancer.

Affordability of the Health Expenditures of Insured Americans Before the Affordable Care Act.

Central to the Affordable Care Act is the notion of affordability and the role of health insurance in making otherwise unaffordable health care affordable. We used data from the 1996 to 2008 versions of the Medical Expenditure Panel Survey to estimate the portion of overall health care expenditures by insured respondents that would otherwise have been beyond their disposable incomes and assets. We found that about one third of insured expenditures would have been unaffordable, with a much higher percentage among publicly insured individuals. This result suggests that one of the main functions of insurance is to cover expenses that insured individuals would not otherwise be able to afford.
