Costs and Impact of Disease in Adults with Sickle Cell Disease: A Pilot Study.

Limited data are available to characterize sickle cell disease (SCD) related disease burden and outcomes. We assessed the feasibility of collecting data to estimate illness burden in adults with SCD; investigated factors associated with health-related quality of life (HRQoL); and estimated societal burden. We recruited 32 adults with SCD. We collected data on fatigue, HRQoL and the Work Productivity and Activity Impairment via patient survey. Healthcare utilization was abstracted for the 12 months prior to enrollment using medical chart review. Mean (standard deviation) age was 36.7 (10.6) years, 84.4% had hemoglobin (Hb)SS/Sthal0 disease, and 81.3% reported chronic pain (experiencing pain on ≥3 days per week in the past 6 months). Mean EQ-5D-3L VAS was 63.4, index score was 0.79. The mean fatigue score was 57.9 (range 33.7-75.9). Higher fatigue score was correlated with lower EQ-5D index score (correlation coefficient r=-0.35, p=0.049), and ASCQ-Me scores, including pain (r=-0.47, p=0.006), sleep (r=-0.38, p=0.03), and emotion (r=-0.79, p<0.0001). The number of hospitalizations was negatively correlated with HRQoL (all p<0.05). Patients who reported chronic pain had significantly lower mean ASCQ-Me sleep scores (48.3 vs. 57.1, p=0.04) and EQ-5D index scores (0.72 vs. 0.89, p=0.002) than those without chronic pain. Mean estimated annual per-person costs were $51,779 (median: $36,366) for total costs, $7,619 ($0) for indirect costs (estimated from lost earnings of participants), and $44,160 ($31,873) for medical costs. Fatigue, SCD complications, hospitalization and chronic pain negatively impact HRQoL in this cohort. This sample experienced a high economic burden, largely from outpatient doctor visits.

Trends in prescribing practices for management of haemophilia: 1999-2021.

INTRODUCTION: People with haemophilia rely on specialists for their care, yet the specific dosing regimens of treatments prescribed by these specialists have not been widely studied. AIM: The objective of this study is to describe trends in clinician prescribing practices for the management of haemophilia in the United States (US). METHODS: We administered surveys to members of the Hemostasis and Thrombosis Research Society via paper surveys at its in-person annual symposia in 1999 and 2015, and an online survey in 2021. The surveys collected information on haemophilia treatments including factor dosing, inhibitor therapy and gene therapy. RESULTS: Clinicians treating haemophilia for more than 50% of their practice time have increased from 37.5% of respondents in 1999 to 46.3% in 2021. Clinicians prescribing factor concentrates at >40 units/kg for routine bleeding events increased from 0% in 1999 to 29.3% in 2021 in haemophilia A (HA) and from 22.5% to 87.8% in haemophilia B (HB). In 2021, the clinicians reported prescribing emicizumab to treat HA patients (>89.5% paediatric, >85.7% adult) with or without inhibitors at least some of the time. Approximately 78.0% of respondents reported that they expected to recommend gene therapy at least some of time. CONCLUSION: These data indicate changing trends in prescribing practices among US haemophilia specialists during the past 22 years. Preference for high doses of factor (>40 units/kg) has increased during this period. Emicizumab prophylaxis has been prescribed for patients with and without HA inhibitors. Clinicians expect gene therapy to have value for some haemophilia patients.

Depression and anxiety in persons with Von Willebrand disease.

OBJECTIVE: We assessed sociodemographic and clinical characteristics associated with depression and anxiety in individuals with Von Willebrand disease (VWD) aged ≥12 years. METHODS: The study collected data on patients' sociodemographic, joint problems and health-related quality of life (HRQoL) using EQ-5D-3L, 8-item patient health questionnaire for depression and 7-item Generalized Anxiety Disorder Questionnaire from participants in seven geographically diverse US haemophilia treatment centres. RESULTS: Analyses included 77 participants. The rates of depression and anxiety were 63.6% and 58.3%, respectively. Persons with low VWF displayed higher rates of depression (86.7%) or anxiety (69.2%) compared to those with VWD (58.1%, p = .04 for depression, and 55.9%, p = .38 for anxiety). Logistic regression analyses demonstrated that having joint problems (odds ratio [OR] = 6.3, confidence interval [CI] = 2.0-20.1) was the most important variable associated with depression, followed by being single, divorced, widowed, or separated in adult participants or parents of participants age < 18 years (OR = 7.0, CI = 1.7-29.0. The most important variable associated with anxiety was being single or lacking a partner (OR = 10.8, CI = 2.5-47.5), followed by age 12-17 years old (OR = 6.7, CI = 1.6-26.9), or having worse health compared to 3-months ago (OR = 12.3, CI = 1.3-116.2). Mean covariates adjusted EQ visual analogue scale score was significantly lower among persons with depression (68.77 ± 3.15 vs. 77.58 ± 4.24, p = .03) than those without depression. CONCLUSIONS: Our study revealed concerning levels of depression and anxiety in this VWD sample. Lack of social support was determined an important factor associated with depression and anxiety in this sample. Mental health screening is critical in VWD clinical evaluation and care.

Comorbidities, Health-Related Quality of Life, Health-care Utilization in Older Persons with Hemophilia-Hematology Utilization Group Study Part VII (HUGS VII).

Purpose: We compare the impact of hemophilia on comorbidities, joint problems, health-related quality of life (HRQoL) and health-care utilization between two age groups: 40-49 years and ≥50 years. Patients and Methods: The HUGS VII study recruited persons with hemophilia A or B age ≥40 years. Participants completed surveys to collect data on sociodemographic and clinical characteristics, hemophilia treatment regimen, pain, joint problems, comorbidities, HRQoL, depression and anxiety, at baseline and 6-months later. Clinical chart reviews documented hemophilic severity and treatment. Results: The sample includes 69 males, 65.2% aged ≥50 years, 75.4% with hemophilia A. Individuals ≥50 years were more likely to have mild or moderate hemophilia (68.9% vs 41.7%, P = 0.03) than those 40-49 years old. Among persons with mild/moderate hemophilia, those ≥50 years old reported a higher rate of joint pain (83.9% vs 70.0%, P = 0.34 at baseline, 91.3% vs 57.1%, P = 0.06 at follow up) or range of motion limitation (73.3% vs 60.0%, P = 0.43 at baseline, 73.9% vs 28.6%, P = 0.04 at follow up) than the younger group. Compared to the younger group, the older group reported fewer emergency room visits (4.5% vs 21.7%, P = 0.03), and physical therapy visits (15.9% vs 43.5%, P = 0.01) at baseline. The sample depression rate was 85.7%, but the differences among the age groups were not significant. The mean covariate-adjusted EQ-5D index score was lower in older persons (0.77 vs 0.89, P = 0.02). Conclusion: Older persons with hemophilia in this sample are over-represented by individuals with mild/moderate disease, potentially due to premature death among those with severe disease. Although this group included a larger proportion of individuals with mild disease than the younger group, they experienced lower quality of life, more comorbidities both of aging and of hemophilic arthropathy, and lower rates of health-care utilization.

Young adults with hemophilia in the U.S.: demographics, comorbidities, and health status.

Improvements in hemophilia care over the last several decades might lead to expectations of a near-normal quality of life for young adults with hemophilia. However, few published reports specifically examine health status indicators in this population. To remedy this knowledge gap, we examined the impact of hemophilia on physical and social functioning and quality of life among a national US cohort of 141 young men with hemophilia aged 18-34 years of age who received care at 10 geographically diverse, federally funded hemophilia treatment centers in 11 states between 2005 and 2013 and enrolled in the Hemophilia Utilization Group Studies. Indicators studied included educational achievement, employment status, insurance, health-related quality of life, and prevalence of the following comorbidities: pain, range of motion limitation, overweight/obesity, and viral status. The cohort was analyzed to compare those aged 18-24 to those aged 25-34 years. When compared to the general US adult population, this nationally representative cohort of young US adults with hemophilia experienced significant health and social burdens: more liver disease, joint damage, joint pain, and unemployment as well as lower high-school graduation rates. Nearly half were overweight or obese. Conversely, this cohort had higher levels of health insurance and equivalent mental health scores. While attention has typically focused on newborns, children, adolescents, and increasingly, on older persons with hemophilia, our findings suggest that a specific focus on young adults is warranted to determine the most effective interventions to improve health and functioning for this apparently vulnerable age group.

Burden of illness: direct and indirect costs among persons with hemophilia A in the United States.

OBJECTIVE: To examine the direct and indirect costs of hemophilia care among persons with hemophilia A in the US. METHODS: Observational data were obtained from HUGS-Va, a multi-center study from six federally supported hemophilia treatment centers (HTCs). Eligible individuals completed a standardized initial questionnaire and were followed regularly for 2 years to obtain information on work or school absenteeism, time spent arranging hemophilia care, and unpaid hemophilia-related support from caregivers. Data from 1-year healthcare utilization records and 2-year clotting factor dispensing records measured direct medical costs. Indirect costs were imputed using the human capital approach, which uses wages as a proxy measure of work time output. RESULTS: A total of 222 patients with complete data were included in the analysis. Two-thirds had severe hemophilia and the mean age was 21.1 years. The use of prophylaxis in severe hemophilia patients is associated with statistically significant reduction in the numbers of emergency department (ED) visits and bleeding episodes compared with those who were treated episodically. From the societal perspective, mild hemophilia costs $59,101 (median: $7519) annually per person, $84,363 (median: $61,837) for moderate hemophilia, $201,471 (median: $143,431) for severe hemophilia using episodic treatment, and $301,392 (median: $286,198) for severe hemophilia receiving prophylaxis. Clotting factor contributed from 54% of total costs in mild hemophilia to a maximum of 94% for patients with severe hemophilia receiving prophylaxis. CONCLUSION: Hemophilia is a costly disorder not only because of its high medical expenses, but also due to the high indirect costs incurred.

Self-reported barriers to hemophilia care in people with factor VIII deficiency.

BACKGROUND: In 1975, a national network of hemophilia treatment centers (HTCs) was created to increase access to healthcare services for individuals with hemophilia. Studies demonstrate that care in HTCs improves outcomes and reduces costs. PURPOSE: The objective of the study was to assess the association of demographic, insurance, and clinical characteristics with self-reported barriers to HTC utilization. METHODS: Data were collected from six HTCs from 2005 through 2007. Adult participants and parents of children aged <18 years were interviewed. Barriers were assessed by asking whether it was difficult to obtain care in the past 12 months. Chi-square test and logistic regression were used to assess factors associated with self-reported barriers to care. All analyses were performed in 2010-2011. RESULTS: Data for 327 participants (50% adult, 64% severe hemophilia) were analyzed in 2010-2011. Most participants/parents did not report barriers to HTC utilization. However, 46 participants/parents (14%) reported one to six barriers, and 23 reported one barrier. Most frequently reported barriers were "distance to the clinic" for children (44%) and "insurance coverage" for adults (40%). Factors significantly associated with self-reported barriers were: lower income (<$20,000; OR=3.11, 95% CI=1.14-8.45), difficulty finding insurance or obtaining full-year coverage (OR=5.71, 95% CI=2.63-12.41), and decreased state Medicaid coverage for low-income, non-elderly individuals (OR=0.93, 95% CI=0.89-0.98). CONCLUSIONS: This study indicates that, although few people with hemophilia have barriers to care at HTCs, those with lower income, difficulty finding or maintaining adequate insurance coverage, or living in states with lower Medicaid generosity are more likely to report barriers. Identifying and resolving such barriers may improve care access and patient-reported outcomes.
