BackgroundPatients with respiratory disease experience disturbed sleep, but there is no widely accepted measure of sleep impairment due to respiratory disease. We developed and evaluated the psychometric performance of a patient-reported measure to assess the impact on sleep due to respiratory disease, the COPD and Asthma Sleep Impact Scale (CASIS).MethodsIdentification of the items forming the CASIS was guided by patient interviews and focus groups. An observational study involving patients from the US and UK was then conducted to assess the psychometric characteristics of the measure.ResultsQualitative data from 162 patients were used to develop the CASIS (n = 78 COPD; n = 84 asthma). The observational study included 311 patients with COPD and 324 patients with asthma. The final seven items used in the CASIS were identified based on factor and item response theory analyses. Internal consistency was 0.90 (COPD) and 0.92 (asthma), and test-retest reliability was 0.84 (both groups). In the COPD sample, CASIS scores were significantly correlated with the Saint George's Respiratory Questionnaire scores (all p < 0.0001) and differed significantly by patient-reported disease severity, exacerbation status, and overall health status (all p ≤ 0.005). In the asthma sample, CASIS scores were significantly correlated with the Asthma Quality of Life Questionnaire scores (all p < 0.0001) and differed significantly by clinician and patient-reported disease severity, exacerbation status, and overall health status (all p ≤ 0.0005).ConclusionThe CASIS shows good internal consistency, test-retest reliability, and construct validity and may be useful in helping to understand the impact that COPD and asthma have on sleep outcomes.

This study assessed the impact of respiratory syncytial virus–confirmed hospitalizations (RSVH) on caregivers of high-risk preterm infants. Caregivers for infants born at 29 to 35 weeks’ gestational age and hospitalized for confirmed RSV disease responded to measures of self-rated and perceived infant stress (1-7; 7 = very stressful), perceived infant health (0-100; 100 = best imaginable health), and productivity impairment. Data were collected at hospital discharge through 1 month post-discharge. Caregiver responses indicated high stress levels, poor health, and productivity loss were reported at discharge; however, steady improvements were seen through 1 month post-discharge: caregiver-rated stress (from 6 to 2), infant stress (5 to 1), caregiver-perceived infant health (64 to 84), and productivity loss (mothers: 91% to 31%; fathers: 81% to 18%). Qualitative results indicated emotional impact, family routine disruption, financial concerns, and medical concerns persisted at 1 month post-discharge. This study found the caregiver burden of RSVH persists at least 1 month beyond discharge.

BACKGROUND: Endometriosis-related pain symptoms have a negative impact on health-related quality of life and productivity. In fact, as endometriosis-related symptom severity and the number of symptoms experienced increases, health-related quality of life decreases. Dysmenorrhea and nonmenstrual pelvic pain are prominent symptoms experienced by women with endometriosis and were shown to have improved with the oral, nonpeptide gonadotropin-releasing hormone antagonist, elagolix.

The LCOPD is a new measure examining the everyday impact of living with COPD. It demonstrates good scaling properties and may prove valuable in understanding treatment benefits.

BACKGROUND:In a randomized controlled trial (RCT) of patients with recurrent, platinum-sensitive ovarian cancer, the combination weekly docetaxel and carboplatin was associated a with progression-free survival (PFS) of 13.7 months compared with 8.4 months for sequential, single-agent docetaxel followed by carboplatin. The objective of the current study was to construct a cost-utility model to compare these 2 regimens with the incorporation of prospectively collected quality-of-life (QoL) data. METHODS: An RCT of concurrent docetaxel and carboplatin (cDC) versus docetaxel followed by carboplatin (sequential docetaxel and carboplatin [sDC]) was the basis for a Markov decision model, and the primary effectiveness outcome was PFS. Costs were estimated using US dollars based on Medicare reimbursements for chemotherapy regimens, bone marrow support, and management of adverse events. QoL data obtained using the Functional Assessment of Cancer Therapy-General questionnaire were converted to utilities. Costs and incremental cost-effectiveness ratios (ICERs) were reported in US dollars per quality-adjusted life year (QALY). Extensive 1-way sensitivity analyses and a Monte Carlo probabilistic sensitivity analysis were performed. RESULTS: The least expensive strategy was sDC, which cost an average of $20,381, compared with cDC, which cost an average of $25,122. cDC had an ICER of $25,239 per QALY compared with sDC. cDC remained cost-effective, with an ICER <$50,000 per QALY, over a range of costs and estimates. In Monte Carlo sensitivity analysis using a $50,000 per QALY willingness-to-pay threshold, cDC was either dominant or cost-effective with an ICER <$50,000 per QALY in 83% of simulations. CONCLUSIONS: Combined weekly cDC appeared to be cost-effective compared with sDC as treatment strategy for patients with platinum-sensitive ovarian cancer, even when accounting for slightly lower QoL during treatment.

Acid sphingomyelinase deficiency (ASMD), historically known as Niemann–Pick disease (NPD) types A, A/B, and B, is a rare, progressive, potentially fatal lysosomal storage disease with a spectrum of phenotypes. Little is known about how ASMD symptoms affect the lives of patients and their caregivers. In a cross-sectional qualitative study conducted in the US and UK, and in collaboration with the National Niemann–Pick Disease Foundation (US) and Niemann–Pick UK, we investigated the symptom experience of patients with ASMD types B and A/B and explored how the disease impacts their and their caregivers’ lives. The study included 17 adult patients (mean age 38.7 years, 12 female), three caregivers of adults with ASMD, 12 pediatric/adolescent patients with ASMD (mean age 10.5 years, six female), and 12 caregivers of pediatric/adolescent patients with ASMD. The most commonly reported disease manifestations were respiratory (n = 26, 89.7%), abdominal (n = 25, 86.2%), and musculoskeletal symptoms (n = 23, 79.3%); excessive bleeding or bruising (n = 20, 69%); fatigue (n = 20, 69%); gastrointestinal symptoms (n = 18, 62.1%); and headache (n = 15, 51.7%). ASMD was reported to negatively impact patients’ physical function (n = 23, 79.3%), self-esteem (n = 18, 62.1%), emotions (n = 16, 55.2%), social function and relationships (n = 16, 55.2%), and personal care (n = 9, 31%). Providing care for individuals with ASMD negatively affected caregivers’ emotional well-being (n = 12, 80%), social function (n = 4, 26.7%), relationships (n = 6, 40%), and financial security (n = 7, 46.7%). The physical toll of providing care, the need for lifestyle changes, and the responsibility for making medical decisions added to the burden for caregivers. Alternatively, some caregivers noted that caring for a loved one enhanced their spirituality, providing them with a different outlook on life and a deeper personal resolve. This study showed that ASMD is a substantial burden for patients and caregivers, with long-term physical, emotional, social, and financial impacts. The study confirmed commonly known manifestations of ASMD, especially respiratory problems, but also identified less recognized ones, such as dermatological complications. The data collected and insight gained from this study should enhance clinical care, help evaluate new treatments, and inform health care decision making for patients with ASMD.

BackgroundAdenomyosis is a poorly understood, benign disease of the uterus.ObjectiveIn this study, patient interviews were conducted to characterize the symptoms and impact of adenomyosis.MethodsThis was a cross-sectional study in which women with adenomyosis were recruited from five US clinics and a health-related social network forum. Participants (aged 18–55 years) were pre-menopausal with a history of regular menstrual cycles. Participants were interviewed about their experiences with adenomyosis, symptoms and impacts on day-to-day activities (concept elicitation), and subsequently about the occurrence, relative severity, and impact of symptoms (card-sorting exercise).ResultsIn total, 31 women were interviewed. Mean duration since onset of first adenomyosis symptom was 5.7 years; 41.9% reported severe/very severe adenomyosis. Over 50 symptoms and 30 impacts of adenomyosis were reported in the concept elicitation; 87% of symptoms were reported after 7 interviews and 78% of impacts after 5 interviews, indicating a condition with a significant symptom burden and a consistent presentation. The most common symptoms were heavy menstrual bleeding (87%), cramps (84%), and blood clots during menstrual bleeding (84%). The most common impacts were burdensome self-care hygiene (71%), and fatigue/low energy (71%). In the card-sorting exercise, the most commonly endorsed symptoms were pain during menstruation/menstrual cramps and heavy menstrual bleeding (both frequently rated as severe). The symptom with the highest impact was heavy menstrual bleeding.ConclusionInitiatives to understand women’s experiences with adenomyosis may improve management of the condition. This study provides a first step in understanding their experience and new information on the symptom profile of adenomyosis.Electronic supplementary materialThe online version of this article (10.1007/s40271-017-0284-2) contains supplementary material, which is available to authorized users.
