Objectives:
Von Willebrand disease (VWD) is the most common bleeding disorder in children and adolescents. Its varied clinical presentation contributes to challenges and delays in diagnosis and management. We characterized diagnosis, bleeding, and treatment patterns in children (2-11yrs) and adolescents (12-17yrs) with VWD.
Methods:
This retrospective database analysis utilized data from IQVIA PharMetrics Plus Database of medical insurance claims for VWD patients (ICD-9 286.4) from 01/01/2006 to 06/30/2015. Patients included had ≥2 medical claims for VWD and continuous enrollment for ≥2 years, to ensure higher likelihood of definitive VWD diagnosis, before/after their 1st VWD claim. Pre-diagnosis period included 18mos of data before diagnosis. Post-diagnosis period included 7-24mos post-diagnosis data. Data from the first 6-month post-diagnosis period were excluded due to data variability, suggestive of treatment optimization. Descriptive statistics were used to summarize patient demographic/clinical characteristics, including types of bleeding episode (BE), rates, outcomes; treating physician specialty; and type of VWD treatment, in both pre-/post-diagnosis periods.
Results:
475/1087 patients identified were children (43% female; mean age at diagnosis 6.9yrs; 612 were adolescents (74% female; mean age at diagnosis 14.9yrs). The top 3 treating physician specialties seen by children in the pre-/postdiagnosis periods, respectively, were hospitalists (21%/9%), primary care physicians (16%/7%), and hematologists (11%/3%). Adolescents were mostly seen by hospitalists (30%/15%), primary care physicians (25%/16%), and obstetrician gynecologists (19%/15%). 11% of children and adolescents saw a hematologist prior to diagnosis, compared with 3% and 5%, respectively, post-diagnosis. A 17%/15% decrease in bleed claims in the pre-/post-diagnosis period was observed among children (40%/23%) and adolescents (59%/44%), respectively. The most common type of BE among children in the pre-/post-diagnosis periods was epistaxis (19%/10%). Heavy menstrual bleeding was the most common BE among adolescents in both the pre-/post-diagnosis periods (40%/30%; in females 54%/40%). Epistaxis was the second most common BE among adolescents in both the pre-/post-diagnosis periods (11%/7%), and in females (9%/5%), but highest among males (17%/12%). Overall, VWD-related treatment claims increased between the pre-/post-diagnosis periods for both children (12%/23%) and adolescents (31%/50%). The most prescribed treatments for bleed management in children were aminocaproic acid (ACA), desmopressin (DDAVP) and nasal cauterization (pre-diagnosis: 5%, 4% and 4%, respectively; post-diagnosis: 11%, 13% and 3%, respectively). For adolescents, the most prescribed treatments, pre- and post-diagnosis respectively, were oral contraceptives (22% and 33%, DDAVP (9% and 19%) and ACA (4% and 11%).
Conclusions:
This analysis demonstrates a decrease in BE claims following VWD diagnosis and a rise in ACA and DDAVP treatment claims in both children and adolescents, and in oral contraceptive claims among female adolescents. Nevertheless, a considerable proportion of children and adolescents continue to experience BEs 6mos post-diagnosis. This emphasizes the need for treatment optimization and improvement in care and management of patients in these age groups.
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.
