Abstract
BACKGROUND Medical technologies have the potential to improve quality and efficiency of healthcare. The design of clinical trials should consider participants' perspectives to optimise enrolment, engagement and satisfaction. This study aims to assess patients' perceptions of their involvement in medical device trials, to inform the designs of future medical technology implementation and evaluation. METHODS Four focus groups were undertaken with a total of 16 participants who had participated in a study testing hospital inpatient remote monitoring devices. Interviews were audio-recorded, transcribed verbatim and underwent thematic analysis. RESULTS Four main themes emerged: patients' motivations for participating in medical device research; patients' perceptions of technology in medicine; patients' understanding of trial methodology; and patients' perceptions of the benefits of involvement in medical device trials. The appeal of new technology is a contributing factor to the decision to consent, although concerns remain regarding risks associated with technology in healthcare settings. Perceived benefits of participating in device trials include extra care, social benefits and comradery with other participants seen using the devices, although there is a perceived lack of confidence in using technology amongst older patients. CONCLUSION Future device trials should prioritise information sharing with participants both before and after the trial. Verbal and written information alongside practical demonstrations can help to combat a lack of confidence with technology. Randomised trials and those with placebo- or sham-controlled arms should not be considered as barriers to participation. Study results should be disseminated to participants in lay format as soon as possible, subject to participant permission.

Abstract
A prospective feasibility study was conducted to determine whether a new wearable device, the Visual Behavior Monitor (VBM), was easy to use and did not present any difficulties with the daily activities of patients. Patients for cataract surgery and refractive lens exchange were randomly selected and screened for inclusion in the study. A total of 129 patients were included in the study as part of a multicenter study. All measurements were performed before surgery. Upon inclusion, patients were trained to wear the device, instructed to wear it for a minimum of 36 h, and were scheduled to return in one week. The VBM measures the distance at which patients’ visual activities are performed, the level of illumination, and head translational and rotational movements along the three axes. On the follow-up visit, patients completed a questionnaire about their experience in wearing the device. All patients underwent standard diagnostic testing, with their cataract grade determined by the Lens Opacities Classification System (LOCS) classification. Results indicate that 87% of patients felt comfortable using the wearable device while 8% of patients responded as not feeling comfortable (5% of patients did not respond to the question). In addition, 91% of patients found it easy to attach the wearable to the magnetic clip while 4% of patients did not find it easy, and 5% of patients did not respond. Overall, patients found the device easy to use, with most reporting that the device was not intrusive.

Abstract
OBJECTIVES For medical devices, benefits other than direct clinical effects may have a large impact on the patients' well-being, but a standardized method for measuring these benefits is unavailable. The objective was to explore potential patient benefits provided by medical devices, and to assess the relative preferences of these benefits in the general Swedish population. METHODS To identify attributes of patient benefit, healthcare personnel within a wide range of disease areas were interviewed. The generalized attributes were then validated among healthcare personnel, patient organizations, and manufacturers; in two pilot studies in the general population; and in two rounds of cognitive interviews. The general population's preferences of the attributes were measured with a usability-tested questionnaire in a final responding sample of 3,802 individuals, representative of the Swedish population. RESULTS Twenty attributes were identified, encompassing aspects of integrity, sense of security, social participation, and convenience. When measuring the relative preferences, the response rate was 37.0 percent, and the results showed that the attributes with the highest preferences concerned reliability, reduced need for assistance, and sense of control of the illness/disability. CONCLUSIONS A set of twenty attributes of patient benefit relevant to users of medical devices was identified and validated. A questionnaire for patient-reported assessment of the benefits provided by a medical device was developed, based on the attributes. The questionnaire, designated MedTech20, provides a generic measurement method for the evaluation of medical devices used in a wide range of diseases/disabilities.

Abstract
BACKGROUND Assessment of health effects of a forest environment is an important emerging area of public health and environmental sciences. PURPOSE To demonstrate the long-term health effects of living in a forest environment on subclinical cardiovascular diseases (CVDs) and health-related quality of life (HRQOL) compared with that in an urban environment. MATERIALS AND METHODS This study included the detailed health examination and questionnaire assessment of 107 forest staff members (FSM) and 114 urban staff members (USM) to investigate the long-term health effects of a forest environment. Air quality monitoring between the forest and urban environments was compared. In addition, work-related factors and HRQOL were evaluated. RESULTS Levels of total cholesterol, low-density lipoprotein cholesterol, and fasting glucose in the USM group were significantly higher than those in the FSM group. Furthermore, a significantly higher intima-media thickness of the internal carotid artery was found in the USM group compared with that in the FSM group. Concentrations of air pollutants, such as NO, NO2, NOx, SO2, CO, PM2.5, and PM10 in the forest environment were significantly lower compared with those in the outdoor urban environment. Working hours were longer in the FSM group; however, the work stress evaluation as assessed by the job content questionnaire revealed no significant differences between FSM and USM. HRQOL evaluated by the World Health Organization Quality of Life-BREF questionnaire showed FSM had better HRQOL scores in the physical health domain. CONCLUSIONS This study provides evidence of the potential beneficial effects of forest environments on CVDs and HRQOL.

Abstract
One of the current ultimate goals of orthotopic liver transplantation (OLT) is the improvement of patients' health-related quality of life (HRQOL). The purpose of this study was to look at the effects of socioeconomic and demographic differences on the short-term and long-term HRQOL outcomes of OLT recipients. Three hundred three adult OLT recipients who were seen at the University of California Los Angeles were administered the Medical Outcomes Study Short Form 36 (SF-36), the Chronic Liver Disease Questionnaire (CLDQ), and a demographic survey. A parsimonious model of 12 socioeconomic and demographic predictors was identified. Their simultaneous influence on each SF-36 and CLDQ HRQOL domain score was evaluated with multivariate linear regression and backward selection. Hepatitis C virus impaired HRQOL; this was shown in the SF-36 Vitality and Bodily Pain domains and in most CLDQ domains. Females experienced more HRQOL impairment only within the CLDQ Abdominal Symptoms domain. OLT recipients who were married had better SF-36 Role-Emotion domain scores. OLT recipients with more than 12 years of education had better SF-36 Physical Functioning scores. Employed OLT recipients had less HRQOL impairment; this was evidenced by better scores in multiple domains of the SF-36 and the CLDQ. OLT patients with health maintenance organization or preferred provider organization insurance had higher HRQOL scores within almost all SF-36 and CLDQ domains. Patients with a mix of public and private insurance had significantly higher HRQOL scores in comparison with those with only public insurance. Identifying patients at higher risk for worse HRQOL scores, less satisfaction with OLT results, and greater problems with fatigue or mental health stressors will assist transplant centers in using their medical teams to develop early interventions and multidisciplinary approaches to improve HRQOL outcomes after OLT.

Ease of use and preference for a new disposable self-injection pen compared with a reusable pen for administering recombinant human growth hormone: A multicenter, 2-month, single-arm, open-label clinical trial in patient-caregiver dyads. Clin Ther 2011; 32:2036-47.

Abstract
BACKGROUND Improved ease of use of drug-delivery devices may enhance compliance. Development of an easier-to-use device for administration of recombinant human growth hormone (rhGH) may thus be beneficial for patients and their caregivers. OBJECTIVE This study compared ease of use and preference for a new disposable rhGH injection pen relative to previous experience with the currently available reusable pen in standard practice. Both pens deliver the same formulation of rhGH. METHODS This multicenter, single-arm, open-label study assessed ease of use and preference for the 2 injection pens in patient-caregiver dyads. Eligible children were aged 8 through 18 years, were currently being treated with rhGH, and had been compliant with use of the current reusable pen for ≥ 3 months before study entry. A validated self-reported Injection Pen Assessment Questionnaire was administered twice during the study-at baseline (to assess perceptions of the reusable pen) and after 2 months of use of the new disposable pen-to assess ease of use of the individual pens (rated on a 5-point Likert-type scale), the comparative ease of use of the 2 pens, and pen preference. The primary end point was the proportion of dyads who rated the new pen as no different or easier to use than the current pen. Regardless of treatment or suspected causal relationship to the investigational product, all observed or volunteered adverse events (AEs) were recorded and rated as mild, moderate, or severe. RESULTS Of 137 screened dyads, 136 (91 boys, 45 girls) were included in the safety population and 133 were included in the efficacy population. The children had a mean age of 12.3 years, a mean weight of 42.2 kg, a mean height of 145.9 cm, and a mean body mass index of 19.3 kg/m(2); 84.6% of the children were white. The majority (82.4%) of adult dyad members were subjects' mothers. The adult dyad members were more likely than the child members to be responsible for preparing the injection (82.0%) and administering the injection (72.9%). Overall, 73.7% of dyads rated the new disposable pen no different or easier to use than the reusable pen (95% CI, 66.2%-81.2%), and 65.2% rated the disposable pen no different or preferable to the reusable pen (95% CI, 57.0%-73.3%). Overall, 60 all-causality AEs occurred in 28 subjects (20.6%), most of them (93.3%) either mild or moderate in intensity. Eight device-related AEs occurred in 7 subjects (5.1%) (injection-site hematoma in 3 and injection-site pain in 5). The most common AEs were headache (7 events), injection-site pain (5), upper respiratory tract infection (4), and pyrexia (4). No deaths or serious AEs were reported. CONCLUSIONS Nearly three quarters of patients and caregivers reported that the new disposable pen was no different or easier to use than the reusable pen, and nearly two thirds preferred the disposable pen. No safety concerns were identified. The findings suggest that the improvements in the new pen were recognized by patients and caregivers.

Abstract
OBJECTIVE To evaluate the reliability and validity of Neurologic Quality of Life (NeuroQOL) item banks that assess quality-of-life (QOL) domains not typically included in poststroke measures. DESIGN Secondary analysis of item responses to selected NeuroQOL domains. SETTING Community. PARTICIPANTS Community-dwelling stroke survivors (n=111) who were at least 12 months poststroke. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Five measures developed for 3 NeuroQoL domains: ability to participate in social activities, satisfaction with participation in social activities, and positive psychologic function. RESULTS A single bank was developed for the positive psychologic function domain, but 2 banks each were developed for the ability-to-participate and satisfaction-with-participation domains. The resulting item banks showed good psychometric properties and external construct validity with correlations with the legacy instruments, ranging from .53 to .71. Using these measures, stroke survivors in this sample reported an overall high level of QOL. CONCLUSIONS The NeuroQoL-derived measures are promising and valid methods for assessing aspects of QOL not typically measured in this population.

Abstract
Background Numerous pen devices are available to administer recombinant Human Growth Hormone (rhGH), and both patients and health plans have varying issues to consider when selecting a particular product and device for daily use. Therefore, the present study utilized multi-dimensional product analysis to assess potential time involvement, required weekly administration steps, and utilization costs relative to daily rhGH administration. Methods Study objectives were to conduct 1) Time-and-Motion (TM) simulations in a randomized block design that allowed time and steps comparisons related to rhGH preparation, administration and storage, and 2) a Cost Minimization Analysis (CMA) relative to opportunity and supply costs. Nurses naïve to rhGH administration and devices were recruited to evaluate four rhGH pen devices (2 in liquid form, 2 requiring reconstitution) via TM simulations. Five videotaped and timed trials for each product were evaluated based on: 1) Learning (initial use instructions), 2) Preparation (arrange device for use), 3) Administration (actual simulation manikin injection), and 4) Storage (maintain product viability between doses), in addition to assessment of steps required for weekly use. The CMA applied micro-costing techniques related to opportunity costs for caregivers (categorized as wages), non-drug medical supplies, and drug product costs. Results Norditropin® NordiFlex and Norditropin® NordiPen (NNF and NNP, Novo Nordisk, Inc., Bagsværd, Denmark) took less weekly Total Time (p < 0.05) to use than either of the comparator products, Genotropin® Pen (GTP, Pfizer, Inc, New York, New York) or HumatroPen® (HTP, Eli Lilly and Company, Indianapolis, Indiana). Time savings were directly related to differences in new package Preparation times (NNF (1.35 minutes), NNP (2.48 minutes) GTP (4.11 minutes), HTP (8.64 minutes), p < 0.05)). Administration and Storage times were not statistically different. NNF (15.8 minutes) and NNP (16.2 minutes) also took less time to Learn than HTP (24.0 minutes) and GTP (26.0 minutes), p < 0.05). The number of weekly required administration steps was also least with NNF and NNP. Opportunity cost savings were greater in devices that were easier to prepare for use; GTP represented an 11.8% drug product savings over NNF, NNP and HTP at time of study. Overall supply costs represented <1% of drug costs for all devices. Conclusions Time-and-motion simulation data used to support a micro-cost analysis demonstrated that the pen device with the greater time demand has highest net costs.

Abstract
With improvements in patient and graft survival after liver transplantation, recipient quality of life (QOL) has become an important focus of patient care and clinical outcomes research. To provide a better understanding of the instruments used to assess QOL in the adult liver transplant population, we conducted a systematic review of the MEDLINE database and Cochrane library. Our review identified 128 relevant articles utilizing more than 50 different QOL instruments. Generic health status instruments are the most commonly used, and among them the Medical Outcomes Study Short Form-36 (SF-36), the Hospital Anxiety and Depression Scale (HADS), and the Beck Depression Inventory (BDI) are the most prevalent. Few studies (16%) included targeted, disease-specific instruments. The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) Quality of Life questionnaire, the Liver Disease Quality of Life questionnaire, and the Chronic Liver Disease questionnaire are the most frequently employed targeted instruments; however, these instruments have been designed to assess QOL in patients with chronic liver disease rather than patients after liver transplantation. The present review focuses on the psychometric properties of the existing QOL instruments and discusses their individual strengths and limitations in evaluating liver transplantation recipients. The lack of a gold-standard QOL instrument for liver transplant recipients is an impediment to cross-study comparisons. We conclude that the development of a QOL instrument specifically for liver transplant recipients will improve QOL assessment in this population leading to a more nuanced understanding of the factors that influence transplant recipients' well-being.
