Healthcare resource utilization and costs associated with long-term corticosteroid exposure in patients with systemic lupus erythematosus.

Objective To evaluate the association between exposure to oral corticosteroids and future healthcare resource utilization and costs for patients with systemic lupus erythematosus. Methods Adults diagnosed with systemic lupus erythematosus (index date) between 1 January 2008 and 30 June 2013 and naive to oral corticosteroids with continuous health plan enrollment for ≥6 months pre- and ≥5 years post-index were identified from a large health plan claims database. Per-patient monthly average daily dose of oral corticosteroids (prednisone or its equivalent) was calculated for the first 2 years post-index to categorize patients into four steroid exposure cohorts: low (≤5 mg/day), medium (6-20 mg/day), high (>20 mg/day) and no steroids. Differences in healthcare resource utilization and total healthcare costs during the third year post-index across corticosteroid exposure cohorts were modeled with adjustment for baseline characteristics. Results The study included 18,618 systemic lupus erythematosus patients (163 high dose, 1127 medium dose, 6717 low dose and 10,611 no steroids). Compared to low-dose corticosteroid users, high-dose corticosteroid users were more likely to have emergency room visits (39.3% vs. 29.7%; p = 0.0085) and to be hospitalized (21.5% vs. 12.3%; p = 0.0005). After adjustment for baseline characteristics, they also had significantly greater average annual total healthcare costs (US$60,366 vs. US$18,777; p < 0.0001). A 1 mg increase in corticosteroid average daily dose was associated with 1.07 times the average annual costs after adjusting for baseline characteristics ( p < 0.0001). Conclusion Long-term high-dose oral corticosteroid use was associated with significantly greater future healthcare resource utilization and costs. Judicious reduction in daily steroid dose may decrease the imminent economic burden associated with high-dose steroid use in systemic lupus erythematosus.

Impact of haemophilia with inhibitors on caregiver burden in the United States.

Inhibitor development complicates haemophilia treatment and may impact caregiver burden. Compare overall burden of caregivers of children with/without inhibitors in the United States using a novel disease-specific questionnaire and the previously validated CarerQol. An on-line questionnaire with six burden domains (i.e. emotional stress, personal sacrifice, financial burden, medical management, child's pain, and transportation) and three visual analogue scales (VAS) was developed based upon a targeted literature review and previous survey findings. The study sample consisted of caregivers of children with haemophilia. The total burden score was calculated by summing the six individual burden domain scores. Higher scores represented greater burden. Descriptive statistics was performed to examine the sample characteristics. The Wilcoxon rank-sum test was performed to compare burden by inhibitor status. All variables were considered significant at P < 0.001. A total of 310 caregivers completed the survey; 30 of them reported caring for a child with an inhibitor. A majority of caregivers of children with inhibitors were mothers (80.0%) and between 35 and 44 years of age (56.7%). Caregivers of children with inhibitors reported significantly higher median total burden scores (99.0 vs. 76.5, P < 0.0001) and median burden-VAS scores (5.5 vs. 3.0, P < 0.0001), as compared to those caring for children without inhibitors. A similar trend was seen across all the six burden domains, with greatest difference in the median burden scores observed in the 'personal sacrifice' (3.2 vs. 2.0) and 'transportation' (3.3 vs. 2.3) domains. Burden of caregivers should be considered when assessing the psychosocial aspects of managing patients with inhibitors.

Improved real-world glycaemic outcomes with liraglutide versus other incretin-based therapies in type 2 diabetes.

AIM: Liraglutide (LIRA) once-daily has provided greater A1C reductions than either exenatide (EXEN) twice-daily or sitagliptin (SITA) once-daily in head-to-head trials. The objective of this analysis is to compare the real-world clinical effectiveness of these agents in the USA. METHODS: Using the IMS Health (Alexandria, VA, USA) integrated claims database, A1C outcomes in patients aged ≥ 18 years with type 2 diabetes (T2D) who initiated either LIRA, EXEN or SITA (including SITA/metformin) were retrospectively compared. Patients included in the analysis had ≥ 1 prescription for LIRA, EXEN or SITA between January and December 2010 (index period) and persisted with their index treatment regimens for 6 months post-index. Outcomes included changes in A1C from baseline (45 days pre-index through 7 days post-index) to follow-up [6 months post-index (± 45)] and the proportion of patients reaching A1C<7%. Multivariable regression models adjusted for confounding factors (e.g. age, comorbidities, baseline A1C and background antidiabetic therapy). RESULTS: The predicted change in A1C from baseline was greater for LIRA patients compared with both SITA (-1.08 vs. -0.68%; treatment difference 0.40%, p < 0.0001) and EXEN (-1.08 vs. -0.75%; treatment difference 0.32%, p < 0.001). Predicted A1C goal achievement, derived from the multivariate logistic regression model, was higher with LIRA compared with both SITA [64.4% (95% confidence interval, CI: 63.5-65.3) vs. 49.4% (95% CI: 48.5-50.4); p < 0.0001] and EXEN [64.4% (95% CI: 63.5-65.3) vs. 53.6% (95% CI: 52.6-54.6); p < 0.0001]. CONCLUSIONS: In clinical practice, LIRA was associated with significantly greater reductions in A1C and improved glycaemic goal attainment compared with either EXEN or SITA among adult patients with T2D.

Understanding the experience of caring for children with haemophilia: cross-sectional study of caregivers in the United States.

Congenital haemophilia is an inherited bleeding disorder typically diagnosed at birth or shortly thereafter. Haemophilia imposes a significant burden on patients and their caregivers. The aim of the study was to quantify the overall burden of haemophilia on caregivers in the USA using a novel disease-specific questionnaire and the previously validated CarerQol. Targeted literature review and a previous survey conducted by the authors was used to develop an online questionnaire with six burden domains of interest to caregivers (emotional stress, financial, sacrifice, medical management, child's pain and transportation) and several visual analogue scales (VAS). Content validity of the questionnaire was confirmed by three haemophilia caregivers. The study sample consisted of caregivers of children with haemophilia identified via a previously developed opt-in research database. Descriptive statistics were employed for demographic and clinical characteristics; a generalized linear model (GLM) was used to identify factors influencing caregiver burden. A total of 310 caregivers completed the survey (45.5% response rate). Most of the participating caregivers were mothers of a child with haemophilia (88%), between 35 and 44 years of age (48%), and with a college education or a postgraduate degree (63%). 'Child's pain' was identified as the most burdensome domain to caregivers (median score = 3.50 out of 5), followed by 'emotional stress' (2.67), 'financial' (2.40), 'transportation' (2.33), 'sacrifice' (2.17) and 'medical management' (2.00) domains. Although higher income exhibited a protective effect, episodes of bleeds, current presence of an inhibitor and lower caregiver productivity in the past month negatively affected caregiver burden per GLM results. Training and educational programs should potentially be developed to address caregiver burden.

Health-related quality of life in haemophilia patients with inhibitors and their caregivers.

Data on the health-related quality of life (HRQoL) of congenital haemophilia patients with inhibitors (CHwI) and their caregivers are limited. To understand the association between patient demo-graphics/clinical characteristics with HRQoL among CHwI patients and caregivers, a survey was developed to assess HRQoL with haemophilia-specific QoL questionnaires (HAEMO-QoL/HAEM-A-QoL). In the cross-sectional study, paper-pencil questionnaires were mailed to 261 US CHwI patients/caregivers in July 2010. Descriptive analyses were performed to characterize HRQoL by age and to identify drivers of impairment, from both patient/caregiver perspectives. HRQoL scores were transformed on a scale of 0-100, with higher scores indicating higher impairment in HRQoL. Ninety-seven respondents completed the HRQoL assessment. HRQoL impairment was higher in adult patients. In children ages 8-16 years, mean HAEMO-QoL total score was 33.8 (SD = 15.5), and 35.0 (SD = 16.1) in children ages 4-7 years; for adult patients the mean HAEM-A-QoL total score was 42.2 (SD = 14.8). Adults reported highest impairment in the 'sports/leisure' subscale (Mean = 62.5, SD = 18.7), whereas patients 8-16 years reported highest impairment in the 'physical health' subscale (Mean = 50.8, SD = 30.5).Caregivers of patients ages 4-7 years reported greatest impairment within the 'family' subscale (Mean = 55.6, SD = 19.4). Caregivers were ''considerably/very much'' bothered by their child's inhibitors and reported higher QoL impairment for their child than parents who were not bothered. Within ChwI patients, HRQoL impairments increased with age and existed across a range of physical/psychosocial domains. In addition, caregiver burden also affected the perceived HRQoL of paediatric CHwI patients. Additional research is considered necessary to further understand the support caregivers need while caring for children with CHwI.

Patient/caregiver perceived benefits and barriers to elective orthopedic surgery (EOS) in patients with congenital hemophilia with inhibitors.

OBJECTIVE: Congenital hemophilia patients with inhibitors are at greater risk for developing arthropathy and orthopedic complications compared to those without inhibitors. Elective orthopedic surgeries (EOS) may be an option for these patients and may provide long-term cost savings due to reduced bleed frequency. However, patient motivations and goals for undergoing or delaying such surgeries are not well understood. A US-based patient/caregiver survey was designed to describe inhibitor patient experiences and outcomes following EOS and to develop a comprehensive understanding of patient preferences for EOS, which are lacking in the literature. METHODS: The paper-pencil questionnaire was mailed to 261 US inhibitor patients/caregivers and included history and timing of EOS, quality-of-life (QoL) and potential benefits of and barriers to receiving EOS. Univariate/bivariate descriptive analyses were performed to characterize those with/without a history of EOS. RESULTS: For 103 subjects who responded, the mean age was 20.9 years. Approximately 25% (n = 26) of respondents underwent EOS, most commonly on the knee (21, 81%); 73.1% of surgery recipients reported the surgery improved or greatly improved their QoL based on single-item response. The highest ranked perceived benefits were less pain, fewer bleeds, and improved mobility. However, the leading concerns reported were lack of improved mobility (62.2%), fear of uncontrolled bleeding (61.3%), and surgical complications, such as blood clot (60.0%). LIMITATIONS: The study consisted of a small sample size, primarily due to the difficulty in trying to reach inhibitor patients or their caregivers, thereby restricting inferential and stratification analysis. CONCLUSIONS: QoL improved for most inhibitor patients who reported having EOS. For those considering surgery, there is optimism about the potential benefits, but realistic concerns associated with bleed control and post-op complications.
