Impact of living with an adult with depressive symptoms among households in the United States.

BACKGROUND: The effect of depressive symptoms on individuals has been widely studied but their impact on households remains less explored. This study assessed the humanistic and economic impact of living with an adult with depressive symptoms on adults without depressive symptoms among households in the United States (US). METHODS: The Medical Expenditure Panel Survey (MEPS) Household Component database was used to identify adults without depressive symptoms living in households with ≥1 adult with depressive symptoms (depression household) and adults without depressive symptoms living in households without an adult with depressive symptoms (no-depression household). Weighted generalized linear models with clustered standard errors were used to compare total income (USD 2020), employment status, workdays missed, quality of life (QoL), and healthcare resource utilization (HRU) between cohorts. RESULTS: Adults without depressive symptoms living in a depression household (n = 1699) earned $4720 less in total annual income (representing 11.3% lower than the average income of $41,634 in MEPS), were less likely to be employed, missed more workdays per year, and had lower QoL than adults without depressive symptoms living in a no-depression household (n = 15,286). Differences in total annual healthcare costs and for most types of HRU, except for increased outpatient mental health-related visits, were not significant. LIMITATIONS: Data is subject to reporting bias, misclassification, and other inaccuracies. Causal inferences could not be established. CONCLUSION: The economic and humanistic consequences of depressive symptoms may extend beyond the affected adults and impact other adult members of the household.

The Economic Burden of Adults with Major Depressive Disorder in the United States (2019).

INTRODUCTION: Previous societal burden estimations for major depressive disorder (MDD) often fail to account for several hidden cost components. This study provides a comprehensive evaluation of societal costs for adults with MDD in the United States (USA) in 2019. The potential impact of a more effective, rapid-acting MDD therapy vs standard of care on the economic burden of MDD was estimated to illustrate the utility of such a framework in evaluating new interventions. METHODS: This study used a prevalence-based human capital approach. Incremental costs (2019 US dollars) per individual with MDD were derived from national survey inputs and published literature and included incremental healthcare costs and indirect costs. For each cost component, the societal costs were extrapolated by multiplying the per-patient costs by the number of individuals with MDD. The impact of a more effective, rapid-acting novel therapy on the economic burden of MDD was then simulated on the basis of these inputs. RESULTS: In 2019, the number of adults with MDD in the USA was estimated at 19.8 million (62.7% female; 32.9% severe MDD), and the incremental societal economic burden of MDD was estimated at $333.7 billion ($382.4 billion in 2023 US dollars), or $16,854 per adult with MDD. The primary cost drivers were healthcare costs ($127.3 billion; 38.1%), household-related costs ($80.1 billion; 24.0%), presenteeism ($43.3 billion; 13.0%), and absenteeism ($38.4 billion; 11.5%). In the simulated scenario, a hypothetical novel therapy with a 50.0% early response rate was associated with a 7.7% reduction in the economic burden of MDD relative to standard of care over 12 months. CONCLUSIONS: The economic burden of MDD is substantial and extends beyond healthcare costs, underscoring the impact of MDD across multiple aspects of life. Such a broad societal perspective should be considered in assessing the impact of the advent of effective, rapid-acting MDD therapies.

The Economic Burden of Adults with Major Depressive Disorder in the United States (2010 and 2018).

BACKGROUND: The incremental economic burden of US adults with major depressive disorder (MDD) was estimated at $US210.5 billion in 2010 (year 2012 values). OBJECTIVE: Following a similar methodology, this study updates the previous findings with more recent data to report the economic burden of adults with MDD in 2018. METHOD: This study used a framework for evaluating the incremental economic burden of adults with MDD in the USA that combined original and literature-based estimates, focusing on key changes between 2010 and 2018. The prevalence rates of MDD by sex, age, employment, and treatment status over time were estimated based on the National Survey on Drug Use and Health (NSDUH). The incremental direct and workplace costs per individual with MDD were primarily derived from administrative claims data and NSDUH data using comparative analyses of individuals with and without MDD. Societal direct and workplace costs were extrapolated by multiplying NSDUH estimates of the number of people with MDD by the direct and workplace cost estimates per patient. The suicide-related costs were estimated using a human capital method. RESULTS: The number of US adults with MDD increased by 12.9%, from 15.5 to 17.5 million, between 2010 and 2018, whereas the proportion of adults with MDD aged 18-34 years increased from 34.6 to 47.5%. Over this period, the incremental economic burden of adults with MDD increased by 37.9% from $US236.6 billion to 326.2 billion (year 2020 values). All components of the incremental economic burden increased (i.e., direct costs, suicide-related costs, and workplace costs), with the largest growth observed in workplace costs, at 73.2%. Consequently, the composition of 2018 costs changed meaningfully, with 35% attributable to direct costs (47% in 2010), 4% to suicide-related costs (5% in 2010), and 61% to workplace costs (48% in 2010). This increase in the workplace cost share was consistent with more favorable employment conditions for those with MDD. Finally, the proportion of total costs attributable to MDD itself as opposed to comorbid conditions remained stable at 37% (38% in 2010). CONCLUSION: Workplace costs accounted for the largest portion of the growing economic burden of MDD as this population trended younger and was increasingly likely to be employed. Although the total number of adults with MDD increased from 2010 to 2018, the incremental direct cost per individual declined. At the same time, the proportion of adults with MDD who received treatment remained stable over the past decade, suggesting that substantial unmet treatment needs remain in this population. Further research is warranted into the availability, composition, and quality of MDD treatment services.

The economic burden of adults with major depressive disorder in the United States (2005 and 2010).

BACKGROUND: The economic burden of depression in the United States--including major depressive disorder (MDD), bipolar disorder, and dysthymia--was estimated at $83.1 billion in 2000. We update these findings using recent data, focusing on MDD alone and accounting for comorbid physical and psychiatric disorders. METHOD: Using national survey (DSM-IV criteria) and administrative claims data (ICD-9 codes), we estimate the incremental economic burden of individuals with MDD as well as the share of these costs attributable to MDD, with attention to any changes that occurred between 2005 and 2010. RESULTS: The incremental economic burden of individuals with MDD increased by 21.5% (from $173.2 billion to $210.5 billion, inflation-adjusted dollars). The composition of these costs remained stable, with approximately 45% attributable to direct costs, 5% to suicide-related costs, and 50% to workplace costs. Only 38% of the total costs were due to MDD itself as opposed to comorbid conditions. CONCLUSIONS: Comorbid conditions account for the largest portion of the growing economic burden of MDD. Future research should analyze further these comorbidities as well as the relative importance of factors contributing to that growing burden. These include population growth, increase in MDD prevalence, increase in treatment cost per individual with MDD, changes in employment and treatment rates, as well as changes in the composition and quality of MDD treatment services.

Cost implications of IV versus oral anti-angiogenesis therapies in patients with advanced renal cell carcinoma: retrospective claims database analysis.

OBJECTIVE: Angiogenesis inhibitors (AI) are promising novel treatments for patients with renal cell carcinoma (RCC). However, IV therapy may impose infection risk from IV catheters, and will include increased costs due to administration and transportation costs. This study evaluated the incremental costs associated with IV administration of selected AI therapies (bevacizumab off-label) compared to oral therapies (sunitinib or sorafenib) for the treatment of RCC. METHODS: Patients with > or =2 RCC claims (ICD-9: 189.0, 198.0) were identified from a US commercial health insurance claims database from 1/2004 to 12/2007. Patients receiving bevacizumab (n = 109) were matched 1:1 to patients receiving sorafenib or sunitinib, and observed from their first AI therapy claim until the last treatment date. AI, inpatient, outpatient and pharmacy costs were calculated on a per-patient per-month (PPPM) basis over the treatment period. Costs were compared between the IV AI group and each separate oral AI group using multivariate Tobit regressions for each category separately, adjusting for demographic and baseline clinical characteristics. This study assessed costs of treatment and did not evaluate the cost-effectiveness of AIs. RESULTS: Mean total medical costs were $13,351, $6998, and $8213 PPPM for bevacizumab, sorafenib, and sunitinib, respectively (p <0.05 for equality). Adjusted incremental total cost for the bevacizumab group was $4951 PPPM compared to sorafenib and $4610 PPPM compared to sunitinib (both p < 0.05). Bevacizumab patients incurred incremental PPPM outpatient services cost compared to sorafenib and sunitinib of $2772 and $2548, respectively (both p < 0.05). CONCLUSIONS: Assuming median progression-free survival of 8.5 months as shown for bevacizumab (Bukowski, et al., J Clin Oncol 2007), the incremental costs would be estimated at $39 188-42 080 per patient compared to those treated with sunitinib or sorafenib. Assuming similar efficacies, oral AI therapies may result in cost savings to patients and healthcare payers over IV therapies.

The economic impact of pre-dialysis epoetin alpha on health care and work loss costs in chronic kidney disease: an employer's perspective.

The objective of the study was to quantify the direct and indirect incremental costs of epoetin alpha (EPO) therapy for anemia in pre-dialysis chronic kidney disease (CKD). Using employer claims data from January 1998 to January 2005, direct (medical and pharmacy) and indirect (sick leave and disability) costs were compared between CKD-anemic patients treated with EPO before dialysis (n = 199) and those not treated with an erythropoiesis-stimulating therapy (EST) (n = 196). Among the results, incremental direct and indirect cost savings for EPO-treated patients were $1443 and $328 per member per month (PMPM) (p < 0.001), respectively, compared to non-EST-treated patients with anemia. After multivariate adjustments, direct and indirect costs remained significantly lower by $852 and $308 PMPM (p < 0.001), respectively, for the EPO-treated group. Direct costs during the first 6 months of dialysis also were significantly lower for the EPO-treated group (who received EPO before dialysis), by $1515 PMPM (p = 0.0267, in multivariate regression). In conclusion, anemic CKD patients treated with EPO before dialysis had significantly lower direct and indirect costs compared to non-EST-treated patients.

Prevalence, referral patterns, testing, and surgery in aortic valve disease: leaving women and elderly patients behind?

BACKGROUND AND AIM OF THE STUDY: The prevalence of aortic valve disease is not well defined, and it is not known to what degree gender and age affect testing and surgery for this condition. The study aim was to describe the prevalence of aortic valve disease in the United States population by extrapolating from administrative claims databases; and to investigate differences associated with gender and age in referral, diagnostic testing, and aortic valve replacement (AVR). METHODS: A claims database of approximately five million privately insured beneficiaries and a 5% sample of Medicare beneficiaries were queried for patients with aortic valve disease. Prevalence was calculated by age group and gender, and extrapolated to the 2005 US population. The proportion of patients with a cardiologist or cardiovascular surgeon visit, performance of echocardiography or stress testing, and AVR within a year of diagnosis was determined. RESULTS: The extrapolated prevalence of aortic valve disease in the US in 2005 was 1.8% (approximately 5.2 million people); in persons aged > or =65 years, prevalence was 10.7%. Women were seen by a specialist, underwent diagnostic tests and underwent AVR at rates significantly lower than men, as did patients aged > or =80 years compared to those aged 65-79 years. AVR was performed at approximately half the rate in women (1.4%) compared to men (2.7%, p <0.001), and in patients aged > or =80 years (1.1%) compared to those aged 65-79 years (2.5%, p <0.001). CONCLUSION: In 2005, approximately 5.2 million adults in the US were estimated to have a diagnosis of aortic valve disease. Advanced age and female gender were associated with lower rates of specialist visits, diagnostic testing, and AVR.

The value of antihypertensive drugs: a perspective on medical innovation.

Using national survey data and risk equations from the Framingham Heart Study, we quantify the impact of antihypertensive therapy changes on blood pressures and the number and cost of heart attacks, strokes, and deaths. Antihypertensive therapy has had a major impact on health. Without it, 1999-2000 average blood pressures (at age 40+) would have been 10-13 percent higher, and 86,000 excess premature deaths from cardiovascular disease would have occurred in 2001. Treatment has generated a benefit-to-cost ratio of at least 6:1, but much more can be achieved. More effective use of antihypertensive medication would have an impact on mortality akin to eliminating all deaths from medical errors or accidents.
