Quality of Life/Outcomes Research

Background:

Von Willebrand disease (VWD) is an inherited bleeding disorder caused by a quantitative or qualitative deficiency of the protein, von Willebrand factor (VWF). There is a lack of clear guidance on best practices to inform the care of people with VWD.

Objectives:

Identify and prioritize the main topics of a collaborative guideline development effort.

Methods:

A scoping survey to prioritize topics to be addressed in a collaborative guideline for VWD was distributed to international stakeholders including patients, caregivers, clinicians, and allied healthcare professionals. The distribution strategy was coordinated by the guideline chairs and representatives of the American Society of Hematology (ASH), the International Society on Thrombosis and Haemostasis (ISTH), the National Hemophilia Foundation (NHF), and the World Federation of Hemophilia (WFH). The survey was conducted in English, French, and Spanish. The survey focused on both diagnosis and management of VWD, using 7-point Likert-scale response options and open ended comments. Descriptive analysis of participants and comparative analysis of results by stakeholder subtype (patients/caregivers versus healthcare providers [HCP]), gender, and income setting was performed. Qualitative conventional content data was analyzed utilizing both deductive and inductive coding processes.

Results:

601 participants responded to the survey (49% patients/caregivers, and 51% HCPs). The highest priority topics identified were diagnostic criteria/classification, bleeding assessment tools, treatment options for women, and surgical patients. In contrast, screening for anemia and plasma-derived therapy versus recombinant therapies were rated the lowest priority topics (figures 1 – 2).

Conclusion:

The survey results highlighted areas of importance in the diagnosis and management of VWD across diverse groups of stakeholders and will direct future guideline efforts. The large number responses (601) and discrete comments (9,500) attest to the interest and involvement of the VWD community in this effort.
 

Helping teens with bleeding disorders prepare to manage their care as they transition to adulthood is a national priority for US Hemophilia Treatment Centers (HTC).  The National HTC Patient Satisfaction Surveys (PSS) reveal high satisfaction with HTC teen transition services. Yet how satisfaction differs comparing HTCs that primarily care for children to HTCs that care for patients throughout the lifespan is unknown.

Objective:

To assess variation in patient satisfaction with US HTC teen transition services by HTC type.

Methods:

The US HTC Network conducted nationally uniform patient satisfaction surveys in 2015 and 2018 on care received, respectively, in 2014 and 2017. A Regional workgroup devised, piloted, and finalized an electronic, two-page survey for self-administration at clinic, or at home, in English or Spanish. Participation was voluntary.  Respondents were anonymous but identified their HTC. Parents completed surveys for children under age 18. The PSS included two teen transition questions for respondents age 12-17 to complete. HTC type was categorized as ‘pediatric’ if >80% of responses were from patients/caregivers of individuals under age 18, and ‘adult’ if >80% were from patients over age 24.  All other HTCs were categorized as ‘lifespan’.  For both years, approximately 26% of HTCs were classified as pediatric, 52% as life-span, and 22% as adult.

Results:

Over 700 teens age 12-17 (or their parents/guardians) from an average of 130 HTCs (94.0%) from all US regions participated in 2015 and 2018. Approximately 96.5% of teens at pediatric HTCs (96.4% - 96.5%) and 96.2% at lifespan HTCs (95.9% - 96.5%) reported being ‘always’ or ‘usually’ (A/U) satisfied with HTC services overall.  On average, 90.4% of teens at pediatric HTCs (90.1% - 90.7%) and 91.0% at lifespan HTCs (90.3%–91.6%) reported being A/U satisfied with how HTC clinic staff talked about how to care for the bleeding disorder as they became an adult. Similarly, 92.5% (92.0%– 92.9%) of teens at pediatric HTCs and 92.5% (92.3%-92.7%) reported being A/U satisfied with how the HTC clinic staff encouraged them to become more independent in managing their bleeding disorder. 

Conclusions:

HTC patients age 12-17 years consistently report very high levels of satisfaction with HTC teen transition services, regardless if the HTC primarily cares for patients up to age 17, or throughout the life-span.  This suggests teens receive support and tools to successfully transition to adult care across the US HTC Network.  A national uniform HTC Patient Satisfaction Survey provides vital information, is feasible to conduct using a regional structure, and well received nationwide.
 

Objective:

We conducted a pilot study using a single open-ended question to elicit patient-perceived challenges and management strategies in individuals with bleeding disorders. The de-identified responses and themes expressed in this study were analyzed. The identification of perceived challenges and management strategies in individuals with bleeding disorders offers the opportunity to improve value based care.

Methods:

This retrospective, cross-sectional cohort study used a sample of convenience at The Hemophilia Center at OHSU. Study population included 20 participants. Inclusion criteria included: ages seven to eighty nine, diagnosed with a bleeding disorder and seen during any outpatient Hemophilia Center clinic visit between March 1, 2017 and April 30, 2018. Participants were included if, during the course of their clinical care, they answered the question, “What is the most significant (or greatest) challenge you have in managing your bleeding disorder and what do you do about it?” Data extracted included question response, age, type and severity of bleeding disorder. Responses were analyzed for themes by the investigators and using qualitative data analysis software. Coded demographic data was correlated.

Summary:

Seven challenge themes were identified: activity restrictions, infusions, emotion/stress, pain, future plans, education and access. Management themes included: self-advocacy, parent directed, activity modification or avoidance, acceptance, inquiry, asking for assistance, planning ahead, resiliency, and peer supports. Younger participants’ (9-17 years) challenges included activity restriction and infusions with management strategies of self-advocacy, activity avoidance and modification. Participants aged 18-57 years highlighted challenges with access to care, infusions, emotion/stress, pain, education and future planning. Management strategies in this group were focused on acceptance, planning ahead, peer support and resiliency. Analysis based on severity of bleeding disorder revealed that subjects with severe hemophilia reported infusions and activity restriction as their most significant challenge, with self-advocacy and activity modification management strategies. Participants with moderate hemophilia reported challenges centered on activity restriction and education of peers, with management strategies being self-advocacy and planning ahead. There were no differences in themes identified when analyzed based on type of bleeding disorder.

Conclusions:

This study characterizes the unique challenges and management strategies described by individuals with bleeding disorders. The themes highlighted the importance of patient voice and can be used to inform individual care decisions.

Objective:

People with hemophilia frequently experience joint bleeds, resulting in pain and functional impairment. The P-FiQ study formally evaluated patient-reported pain descriptions, responses to standardized patient-reported outcomes (PROs) related to pain, and pain management strategies.

Methods:

Participants completed a pain/hemophilia history and 5 PRO instruments. Pain was assessed via 3 PRO instruments: EQ-5D-5L, Brief Pain Inventory v2 Short Form (BPI), and Short Form-36 v2 (SF- 36v2), and these instruments were assessed for reliability, consistency, and correlation with factors including patient-reported characteristics.

Summary:

P-FiQ enrolled 381 adult males with mild-severe hemophilia and a history of pain and/or joint bleeding. Most (65%) self-reported having arthritis/bone/joint problems. Thirty-two percent of participants reported experiencing both acute and chronic pain, 35% chronic pain only, 20% acute pain only, and 15% no pain. Of those reporting acute pain, most described the sensation as “sharp” (77%) or “aching” (65%); for those reporting chronic pain, most described the pain as “aching” (80%) or “nagging” (50%). Ankles (37%) and knees (24%) were commonly reported as the most painful joints. Many participants with acute/chronic pain reported using acetaminophen (62%/55%) or nonsteroidal anti-inflammatory drugs (34%/49%) to treat their pain in the past 6 months. Some participants indicated having moderate/severe/extreme (28%/12%/2%) pain/discomfort “today” as measured by the EQ-5D-5L pain/discomfort domain. For BPI (scale 0-10, 10 is most severe pain), median pain severity scores were 6.0 for worst pain, 3.0 for average pain, 2.0 for current pain, and 1.0 for least pain. Median BPI pain interference scores indicated interference with general activity (3.0), mood (3.0), walking ability (3.0), normal work (3.0), and enjoyment of life (2.0). On SF-36, most participants (90%) reported experiencing bodily pain, and 75% indicated that pain interfered with normal work in the last 4 weeks. Assessments of pain on PROs were highly correlated with one another. The following formal PRO assessments were associated with self-reported pain: pain/discomfort domain of EQ-5D-5L, BPI worst pain, least pain, average pain, and current pain, and SF-36 bodily pain. Greater extent of lifetime routine infusions was also associated with EQ-5D-5L pain/discomfort and SF-36 bodily pain.

Conclusion:

Pain severity and interference in people with hemophilia were identified consistently across several PROs, and correlated with patient-reported pain. In the comprehensive care setting, greater use of formalized assessment tools over time would improve dialogue and pain assessment between healthcare professionals and patients, document and validate the presence and extent of pain, establish and monitor individual goals for pain management interventions, and encourage the exploration of various pain management strategies and the evaluation of their overall quality and effectiveness.

Objectives:

The primary aims of this study are to 1) evaluate the prevalence of depression and anxiety among adult persons with hemophilia (PWH) and 2) explore relationships between depression, anxiety, chronic pain, and adherence to clotting-factor treatment.

Method:

This study used a subset of data from the IMPACT QoL II, a one-time, cross-sectional survey of 200 adults (age >18) with self-reported diagnosis of either Hemophilia A or B who were able to read, write, and speak English. The study was approved by the IRB in the primary investigator’s institution. Participants were a convenience sample recruited at bleeding disorders conferences in 2013-2014 and issued a randomly generated identification number to ensure anonymity. The 139-item survey was completed electronically through SurveyMonkeyTM on a study computer tablet. Participants were given $20 upon completion of the survey, which took 15-45 minutes to complete. The subset of variables evaluated for this analysis included the Faces of Pain Scale-Revised (FPS-R) (chronic pain), level of control over pain each participant feels they have, adherence to clotting factor measured by total scores (higher score=lower adherence) on the VERITAS-PRO or VERITAS-PRN, anxiety measured by the GAD- 7, depression measured by the PHQ-9, and self-report of ever receiving a diagnosis of depression and/or anxiety. The cut-off score for presence of moderate to severe depression or anxiety was 10 on both the PHQ-9 and the GAD-7, scores which have been validated by previous literature in other populations. Lower vs. higher adherence was defined by VERITAS scores in the highest and lowest quartile respectively.

Summary:

Participants with lower treatment adherence (VERITAS score >57) were more likely to have PHQ-9 scores >10 (P=0.02). GAD-7 scores >10 also demonstrated a trend to be associated with lower treatment adherence (P=0.15). 28% of participants reported a diagnosis of depression, but 53% with PHQ-9 scores >10 had not been diagnosed with depression. Similarly, 22% reported a diagnosis of anxiety but 52% with GAD-7 scores >10 had not been diagnosed. Participants who reported non-control of pain were more likely to have PHQ-9 scores or GAD-7 scores >10 (P=0.001 and P=0.013 respectively). There were significant correlations between PHQ-9 and GAD-7 (Rho=0.76, P<0.0001), PHQ-9 and FPS-R (chronic pain) (Rho=0.31, P=0.003), and GAD-7 and VERITAS (P=0.005). These data indicate that depression and anxiety are associated with greater severity of chronic pain, and depression is associated with poorer adherence to clotting factor treatment regimen (prophylaxis or other regimen). Both depression and anxiety appear to be under-diagnosed in PWH.

Objective:

To assess pain and functional impairment through 5 patient-reported outcome (PRO) instruments in non-bleeding adults with hemophilia.

Methods:

Adult men with hemophilia (mild-severe) with history of joint pain/bleeding completed a hemophilia/pain history and 5 PROs (EQ-5D-5L with visual analog scale [VAS], Brief Pain Inventory v2 [BPI-SF], International Physical Activity Questionnaire [IPAQ-SF], SF- 36v2, and Hemophilia Activities List [HAL]) during routine visits. Initial patients were asked to complete the PROs again after their estimated 3-4 hour visit (retest population). PRO scores were calculated from published algorithms. Generally, higher scores indicate better health- related quality of life (HRQoL) and functional status, and greater pain severity/interference.

Summary:

381 Patients were enrolled between October 2013 and October 2014; 164 of the initial 187 completed the retest and are reported here. Median time for completion of the initial survey/PROs was 36.0 minutes and 21.0 minutes for the PRO retest. Most retest subjects had hemophilia A (74.4%) and were white-non-Hispanic (72.6%). Median (Q1, Q3) age was 33.9 (26.9, 46.0), 48.7% were married, 62.6% had some college or graduate education, 80.7% were employed, and 61.0% were overweight or obese. HCV (49.4%) was more common than HIV (16.5%); 61.0% self-reported arthritis/bone/joint problems. Median EQ-5D- 5L VAS was 80.0 (0-100 scale), and EQ-5D-5L health index 0.80 (-0.11-1 scale); 61.6% reported any problems with mobility (29.3% reported moderate/severe problems), 55.8% with usual activities (18.4% moderate/severe), and 22.0% with self-care (4.3% moderate/severe). 73.2% reported pain-discomfort (43.3% moderate/severe), and 41.1% anxiety-depression (14.7% moderate/severe). For BPI, median pain severity was 3.0 (0-10 scale) and pain interference 2.9 (0-10 scale); median worst pain was 6.0, least pain 2.0, average pain 3.0, and current pain 2.0. Pain most impacted general activity, mood, walking ability, and normal work, and least impacted relations with other people. Ankles were the most frequently reported site of pain. Median IPAQ total activity was 693.0 MET/min/week; 49.3% reported no activity in the prior week. Median SF-36v2 scores (0-100 scale) were lower for physical health (39.6) than for mental health (51.6). Median overall HAL score was 76.1 (0-100 scale); complex lower extremity activities were the most impacted activity domain.

Conclusions:

These 5 PRO instruments provide different levels of detail describing the impact of hemophilia on pain and function, and consequently, have varied burdens of administration. PRO data from the retest population demonstrate that most adults with hemophilia experience pain and functional impairment that impacts HRQoL, highlighting the importance of assessments and patient dialogue.

Objective:

Hemophilia is marked by frequent joint bleeding, resulting in acute and chronic pain and functional impairment. Surveys in US adults with hemophilia demonstrate suboptimal pain management and quality of life (QoL). The objective of P-FiQ was to methodologically assess QoL parameters, including functional impairment and pain, and pain management strategies.

Methods:

Adult men with mild-severe hemophilia with a history of joint pain and/or bleeding completed a hemophilia/pain history and various patient-reported outcome assessments (completed twice in “retest” population of initially enrolled patients).

Summary:

Of 164 adults with hemophilia (median age 34) in the “retest” population, more had hemophilia A (74%) than B (26%); 6% had inhibitors. Most had some college-or-above education (63%), 81% were employed, 61% were overweight/obese, and 61% self-reported arthritis/bone/joint problems. Current patient-reported treatment regimens were prophylaxis (42%), on-demand (39%), or mostly on-demand (19%; 25/31 using infusions ahead of activity). One-third (32.9%) reported unrestricted school/work/recreational activities in the prior 6 months; 6.2% reported needing assistance for school/work/self-care, or did not participate in recreational activities because of pain, loss of motion, and weakness. Some patients (31.3%) reported using a cane/crutches/walker (3.8% always) and 7.6% a wheelchair (1.3% always), and 47.0% reported a history of joint surgery (41 knee, 37 ankle, 29 elbow). Patients reported losing an average of 3.7 and 1.8 school/work days in the previous 6 months due to lower and upper extremity problems, respectively. Patients reported that during the prior 6 months they had experienced acute pain only (24%), chronic pain only (33%), or both (29%); 15% reported no pain. Acute pain was most frequently described as sharp (77%), aching (66%), shooting (57%), and throbbing (55%), and chronic pain as aching (74%), nagging (49%), throbbing (44%), and sharp (40%). Most common analgesics in the past 6 months for acute/chronic pain were acetaminophen (69%/58%), NSAIDs (40%/52%), hydrocodone-acetaminophen (29%/33%), oxycodone (12%/11%), and oxycodone- acetaminophen (9%/8%). Most common nonanalgesic treatment strategies reported for acute/chronic pain in the past 6 months were ice (73%/37%), rest (48%/34%), factor or bypassing agent (48%/24%), elevation (34%/28%), relaxation (31%/23%), compression (27%/21%), and heat (25%/15%); other reported strategies include medical marijuana (17%/9%), physical therapy (12%/9%), prayer (11%/8%), faith (9%/8%), alcohol (8%/7%), aquatherapy (5%/6%), illicit drugs (4%/2%), acupuncture (2%/1%), hypnosis (2%/1%), and biofeedback (1%/1%).

Conclusions:

Initial data corroborate the high prevalence of pain and functional disability in adults with hemophilia and highlight opportunities to address clinical assessment, patient dialogue, and management strategies to improve outcomes.
