Impact of trazodone once-a-day on quality of life and functional recovery in adults with major depressive disorder: A prospective, observational study.

BACKGROUND: Health-related quality of life (HRQL) is an important goal for patients with major depressive disorder (MDD), but whether antidepressants improve HRQL in these patients is unclear. Here, we describe the real-world effects of trazodone once-a-day (TzOAD) and selective serotonin reuptake inhibitor (SSRI) treatments on HRQL and functioning in adults with MDD. METHODS: This 8-week prospective, observational, open-label, multicenter study was conducted in adults with moderate or severe MDD for whom TzOAD or SSRI were prescribed as monotherapy. The primary outcome was life enjoyment and satisfaction assessed via the patient-reported Quality-of-Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF) from baseline to week 8. Secondary outcomes included change in Q-LES-Q-SF from baseline to weeks 1 and 2; severity of depressive symptoms using the Montgomery Åsberg Depression Rating Scale (MADRS) and sleep disturbance via the PROMIS SF-SD 8b questionnaire at weeks 1, 2, and 8; and overall functioning via the Sheehan Disability Scale (SDS), hedonic capacity using the Snaith-Hamilton Pleasure Scale (SHAPS), and cognitive dysfunction using the Perceived Deficits Questionnaire (PDQ-5) at baseline and week 8. RESULTS: The study included 208 adults with MDD (mean [SD] age = 50.2 [14.3] years; 68.6% female; 98.4% White). Life enjoyment and satisfaction improved from baseline to week 8 for both treatment groups: Q-LES-Q-SF mean (SD) scores were 27.5 (20.4) for the SSRI group and 39.0 (22.1) for the TzOAD group. Depressive symptoms and sleep disturbances also reduced from baseline to week 8: MADRS (SSRI, -15.7 [8.3]; TzOAD, -21.0 [9.8]); PROMIS SF-SD 8b (SSRI, -9.9 [12.6]; TzOAD, -22.0 [12.6]). Mean change scores in Q-LES-Q-SF, MADRS, and PROMIS SF-SD 8b improved as early as week 1 in both groups. Mean scores also improved from baseline to week 8 on SDS (SSRI, -9.2 [7.4]; TzOAD, -14.3 [7.5]), SHAPS (SSRI, -6.6 [4.3]; TzOAD, -8.3 [4.4]), and PDQ-5 (SSRI, -5.8 [4.5]; TzOAD, -7.7 [5.0]). CONCLUSIONS: In adults with MDD who received TzOAD or SSRIs, overall and individual HQRL domains improved rapidly and in parallel with improvements in depressive symptoms, with a slightly greater improvement observed in the TzOAD group.

Methods and impact of engagement in research, from theory to practice and back again: early findings from the Patient-Centered Outcomes Research Institute.

PURPOSE: Since 2012, PCORI has been funding patient-centered comparative effectiveness research with a requirement for engaging patients and other stakeholders in the research, a requirement that is unique among the US funders of clinical research. This paper presents PCORI's evaluation framework for assessing the short- and long-term impacts of engagement; describes engagement in PCORI projects (types of stakeholders engaged, when in the research process they are engaged and how they are engaged, contributions of their engagement); and identifies the effects of engagement on study design, processes, and outcomes selection, as reported by both PCORI-funded investigators and patient and other stakeholder research partners. METHODS: Detailed quantitative and qualitative information collected annually from investigators and their partners was analyzed via descriptive statistics and cross-sectional qualitative content and thematic analysis, and compared against the outcomes expected from the evaluation framework and its underlying conceptual model. RESULTS: The data support the role of engaged research partners in refinements to the research questions, selection of interventions to compare, choice of study outcomes and how they are measured, contributions to strategies for recruitment, and ensuring studies are patient-centered. CONCLUSIONS: The evaluation framework and the underlying conceptual model are supported by results to date. PCORI will continue to assess the effects of engagement as the funded projects progress toward completion, dissemination, and uptake into clinical decision making.

Impact of uterine fibroid symptoms on health-related quality of life of US women: evidence from a cross-sectional survey.

BACKGROUND: Uterine fibroids (UF) are associated with significant health-related quality of life (HRQL) impact. This study examined the impact of UF symptoms on HRQL. METHODS: An online cross-sectional survey of 18 to 49 year old US women was conducted and collected demographics, UF prevalence, symptoms, and HRQL using the UFS-QOL. Descriptive statistics were used to examine the impact of symptom presence, severity, bothersomeness, and number of UF symptoms on HRQL. Analyses were weighted to match the US female population distribution. Multivariate regressions were performed with each subscale as a dependent variable to examine the impact of individual UF symptoms on HRQL. RESULTS: A total of 59,411 (15.5%) panel members completed the prevalence screener; 4848 met inclusion criteria; 955 had UF and no hysterectomy. Mean age was 40.3; 58% were white; 63% were married/civil union. Common UF symptoms were: lower back pain (65%), fatigue/weariness (63%), bloating (61%), pelvic pain/cramping during menses (63%), and heavy bleeding during menses (54%). Mean UFS-QoL subscale scores were significantly (p < .05) worse among women with a UF symptom versus women without the symptom. Women who rated their UF symptoms as severe had significantly (p < .001) worse UFS-QoL scores than women with mild or moderate symptoms. UFS-QoL subscale scores worsened as the number of symptoms increased. In the regressions, the presence of bleeding and non-bleeding symptoms were related to worse UFS-QoL subscale scores. CONCLUSION: HRQL among women with UF was significantly impacted by UF-related symptoms. Greater impact was observed as the number and severity of symptoms increased.

Challenges of Developing an Observable Parent-Reported Measure: A Qualitative Study of Functional Impact of ADHD in Children.

BACKGROUND: Informant-reported outcome measures, usually completed by parents, are often administered in pediatric clinical trials with the intention of collecting data to support claims in a medical product label. Recently, there has been an emphasis on limiting these measures to observable content, as recommended in the US Food and Drug Administration guidance on patient-reported outcomes. This qualitative study explores the concept of observability using the example of childhood attention deficit/hyperactivity disorder (ADHD). METHODS: Concept elicitation interviews were conducted with children (aged 6-12 years) diagnosed with ADHD and parents of children with ADHD to identify concepts for a potential parent-reported measure of functional impact of childhood ADHD. The observability of each concept was considered. RESULTS: Of the 30 parents (90% females; mean age = 42.0 years), 24 had a child who was also interviewed (87.5% males; mean age = 9.6 years). Areas of functional impact reported by parents and/or children included the following: 1) functioning within the home/family, 2) academic performance, 3) school behavior, 4) social functioning, 5) emotional functioning, and 6) decreased self-efficacy. Parents cited many examples of direct observation at home, but opportunities for observation of some important areas of impact (e.g., school behavior and peer relationships) were limited. CONCLUSIONS: Findings illustrate the substantial functional impairment associated with childhood ADHD while highlighting the challenges of developing informant-reported outcome measures limited to observable content. Because ADHD has an impact on children's functioning in a wide range of contexts, a parent-report measure that includes only observable content may fail to capture important aspects of functional impairment. Approaches for addressing this observability challenge are discussed.

Validation of the 4 week recall version of the Uterine Fibroid Symptom and Health-related Quality of Life (UFS-QOL) Questionnaire.

OBJECTIVE: To assess the psychometric performance of the 4 week recall version of the Uterine Fibroid Symptom and Health-related Quality of Life Questionnaire (UFS-QoL), a patient measure of the severity of uterine fibroid (UF) symptoms and their impact on health-related quality of life (HRQL). METHODS: This was a retrospective analysis of phase 2a data from pre-menopausal women with heavy menstrual bleeding associated with UF. Participants completed the UFS-QoL at Baseline, Treatment Month 3, and Follow-up Month 3 and a daily diary with a Menstrual Bleeding Scale and the UF Daily Symptom Scale throughout the study duration. Descriptive statistics were performed on patient demographic characteristics; analyses were conducted to assess the internal consistency reliability, validity, and responsiveness of the UFS-QoL 4 week recall version. RESULTS: A total of 271 women were enrolled with a mean age of 41.8 years; 74% were black. The UFS-QoL demonstrated excellent internal consistency reliability, with Cronbach's alpha coefficient values >0.70 for each subscale at each study visit. Results indicated good concurrent validity with the UF Daily Symptom Scale items. The women with amenorrhea at Treatment Month 3 had significantly better scores on all UFS-QoL subscales and HRQL Total than women with menstrual bleeding, indicating acceptable discriminant validity. Mean subscale change scores from Baseline to Treatment Month 3 were 19.2 to 39.8. Effect sizes were moderate to large (0.53 to 1.86), demonstrating responsiveness to change. LIMITATIONS: As this study is a post hoc validation of the 4 week recall UFS-QOL, it is limited to the clinical trial data available and does not include a direct comparison to the 3 month recall version of UFS-QOL. CONCLUSIONS: The 4 week recall version of the UFS-QoL demonstrated good internal consistency reliability, concurrent validity, and responsiveness and is psychometrically comparable to the original 3 month recall UFS-QoL. CLINICAL TRIAL REGISTRATION: Data from a phase 2a, cohort design proof of concept study (trial M12-663); ClinicalTrials.gov identifier NCT01441635. Date of Registration: 6 September 2011.

Laxative utilization over time in chronic pain patients with opioid-induced constipation.

AIM: To determine laxative utilization over time among chronic noncancer pain patients with opioid-induced constipation (OIC). SETTING: A prospective longitudinal study conducted in the USA, Canada, Germany and UK. METHODS: Patients on daily opioid therapy for treatment of chronic noncancer pain with OIC were recruited from clinics to complete a survey at Baseline and weeks 2, 4, 6, 8, 12, 16, 20 and 24. RESULTS: 489 patients completed baseline with 452 completing one or more follow-up visits. 128 (28%) were nonlaxative users, 112 (25%) were insufficient laxative users and 212 (47%) were sufficient laxative users. The consistent sufficient laxative users reported the most bowel movements per week. CONCLUSION: The majority of OIC patients do not take or only intermittently take laxatives.

Opioid-Induced Constipation among a Convenience Sample of Patients with Cancer Pain.

BACKGROUND: Little is known regarding the burden of opioid-induced constipation (OIC) among patients who suffer from cancer-related pain. METHODS: A prospective longitudinal study was conducted among cancer patients in the United Kingdom (UK), Canada, and Germany, which included medical record data abstraction, Internet-based patient surveys, and physician surveys. Patients on daily opioid therapy (≥30 mg for ≥4 weeks) for treatment of cancer pain with self-reported OIC were recruited. Response to laxatives was defined by classifying participants into categories of laxative use and evaluating the prevalence of inadequate response. Descriptive statistics were used to evaluate outcomes, including the patient assessment of constipation-symptom (PAC-SYM), patient assessment of constipation-quality of life, EuroQOL-5 dimensions, and global assessment of treatment benefit, satisfaction, and willingness to continue. RESULTS: Recruitment was difficult for this study with only 31 participants completing the baseline survey and meeting criteria for opioid use and OIC (26 UK, 1 Canada, and 4 Germany). Fifty-two percent (n = 16) of participants were male, and all were White. Breast (23%, n = 7), pancreatic (13%, n = 4), and multiple myeloma (13%, n = 4) were the most common cancers. Mean duration of chronic pain and opioid use were 2.3 and 1.3 years, respectively. Participants reported having a mean of 4.4 bowel movements/week in the 2 weeks prior to baseline, of which a mean of 0.9 were spontaneous. Most participants (90%, n = 28) were using at least 1 lifestyle approach to manage their constipation; 65% (n = 20) were taking ≥1 over-the-counter laxative; 19% (n = 6) were taking ≥1 prescription laxative; 23% (n = 7) reported no laxative use in the prior 2 weeks. Moderate-to-severe constipation symptoms on the PAC-SYM were common, and mean scores on health-related quality of life outcomes were comparable to chronic pain populations. CONCLUSION: In this primarily UK sample, there appears to be considerable unmet OIC treatment needs among cancer patients.

Satisfaction with Therapy Among Patients with Chronic Noncancer Pain with Opioid-Induced Constipation.

BACKGROUND: Greater satisfaction with medication is associated with better adherence; however, specific to opioid-induced constipation (OIC), data on the relationship between medication satisfaction and efficacy are lacking. OBJECTIVE: To understand satisfaction with therapy among patients with chronic noncancer pain and OIC. METHODS: A prospective longitudinal study was conducted in the United States, Canada, Germany, and the United Kingdom using web-based patient surveys. Patients on daily opioid therapy for ≥ 74 weeks for the treatment of chronic noncancer pain with OIC were recruited from physician offices and completed a web-based survey at baseline and weeks 2, 4, 6, 8, 12, 16, 20, and 24. When completing each survey, patients selected the remedies used in the previous 2 weeks to relieve constipation; options included natural/behavioral therapies, over-the-counter (OTC) therapies, and prescription laxatives. Patients selected the amount of relief and satisfaction with each selected therapy. Descriptive statistics were calculated; Spearman's correlations were calculated for symptom relief and satisfaction. RESULTS: Mean age of the 489 patients who met the criteria for OIC and completed the baseline survey was 52.6 ± 11.6 years; 62% were female; 85% were white. Increasing levels of relief from constipation were associated with increasing levels of satisfaction for all agents; correlations were > 0.55 and statistically significant (P < 0.001). Among the patients who had used OTC therapies in the 2 weeks prior to baseline, 54% to 73% reported that they were somewhat or very satisfied with the therapy. Yet, of these satisfied patients, 28% to 63% experienced no or only slight relief from the therapy. Twenty percent to 79% of the patients who had used prescription laxatives in the 2 weeks prior to baseline reported being at least somewhat satisfied with the therapy. CONCLUSIONS: These results indicate that there is a high rate of inadequate response to laxatives for patients with OIC that persisted for the 6 months of this study. While increased relief from constipation was associated with increased satisfaction for all therapies, there remains a substantial number of patients who report satisfaction despite having only inadequate relief from OIC that merits further investigation.

Opioid-Induced Constipation Among Patients with Chronic Noncancer Pain in the United States, Canada, Germany, and the United Kingdom: Laxative Use, Response, and Symptom Burden Over Time.

PURPOSE: Estimate rate of laxative inadequate response (LIR) over time among patients with chronic noncancer pain with opioid-induced constipation (OIC). METHODS: A prospective longitudinal study was conducted in United States, Canada, Germany, and United Kingdom. Patients on opioid therapy for ≥4 weeks for chronic noncancer pain and OIC completed an Internet-based survey at Baseline and Weeks 2, 4, 6, 8, 12, 16, 20, and 24. 1xLIR was defined as sufficient laxative use (≥1 laxative ≥ 4 times in past 2 weeks) and inadequate response (<3 bowel movements or ≥ 1 constipation symptom rated Moderate or greater). 2xLIR was sufficient laxative use of ≥2 laxatives from different drug classes and inadequate response. Descriptive statistics and logistic regressions were performed. RESULTS: 489 patients (62% female; 85% white) completed Baseline; 27% reported no laxative use; 25% had insufficient laxative use; 48% had sufficient laxative use. During follow-up, 21-28% of patients had no or insufficient laxative use. Prevalence of 1xLIR was 93% at Baseline and ranged from 59-81% across follow-up; 26% met criteria for 2xLIR (follow-up range: 11-20%). CONCLUSIONS: OIC among noncancer pain patients is a persistent and significant condition with varying utilization and response to laxatives thus increasing the ongoing burden of chronic pain. © 2014 Wiley Periodicals, Inc.

Prevalence of gastroprotective agent (GPA) use in adults with arthritis in the United States.

OBJECTIVE: The prevalence of non-steroidal anti-inflammatory drug (NSAID) and concurrent gastroprotective agent (GPA) use in the US is not known. As such, the prevalence of GPA use among arthritis patients taking NSAIDs was examined. METHODS: Men and women aged ≥ 40 with self-reported arthritis and members of a web-based community panel were invited via e-mail to participate in a web survey. Interested panelists consented and completed the survey. Participants using NSAIDs in the last 30 days were eligible. Questions regarding NSAID and GPA use were asked, likewise adherence to GPA (Morisky scale), comorbid conditions, gastrointestinal (GI) history, and other risk factors. Descriptive analyses and logistic regressions were performed to assess associations with GPA use and adherence. RESULTS: Invitations were sent to 7605 adults; 4108 (54%) responded; 2208 completed. Final sample was 1525 (76%) with osteoarthritis (OA), 354 (18%) with rheumatoid arthritis (RA), and 121 (6%) with both OA and RA. Mean age was 62.0; 64% were female; 83% white; 25% worked full-time, and 39% were retired. Mean duration with arthritis was 13.0 years; 47% and 19% experienced arthritis symptoms 'daily' and 'almost always', respectively. Nearly 43% reported using a GPA and 39% of daily NSAID users reported taking a GPA. Fifty-eight participants (2.9%) were classified as low GI risk, 342 (17.1%) were moderate risk, and 1600 (80.0%) were high risk. Variables significantly associated with GPA use included older age; male gender; being white (vs. Hispanic); taking an NSAID at least daily; taking fewer NSAIDs; taking a Cox-2 inhibitor or prescription NSAID; history of GI conditions; prescription antiplatelet use; and having GI symptoms. Similar variables were associated with GPA adherence. CONCLUSION: Less than half of adult men and women in the US taking a daily NSAID used GPAs and only 37% of high-risk participants were taking GPAs.

Validation of the UFS-QOL-hysterectomy questionnaire: modifying an existing measure for comparative effectiveness research.

OBJECTIVE: The Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaire, a validated patient-reported outcome measure of fibroid symptoms and health-related quality of life, was modified for use posthysterectomy. This study was conducted to psychometrically validate the UFS-QOL-Hysterectomy questionnaire for potential use in comparative effectiveness research to evaluate uterine fibroid treatments. METHODS: This multicenter prospective study enrolled premenopausal women aged 30 to 50 years with uterine fibroids who were scheduled for hysterectomy, myomectomy, or uterine fibroid embolization. All participants completed the UFS-QOL questionnaire and short form 36 health survey at baseline prior to treatment and 6 and 12 months postprocedure. Women with hysterectomy completed the UFS-QOL-Hysterectomy questionnaire during follow-up visits. Internal consistency reliability, discriminant and concurrent validity, and responsiveness were assessed. RESULTS: A total of 274 women were enrolled (107 uterine fibroid embolization, 61 myomectomy, and 106 hysterectomy) and 89 (83%), 55 (90%), and 91 (86%), respectively, completed the 12-month follow-up. The mean age was 43.2 (uterine fibroid embolization), 40.6 (myomectomy), and 44.5 (hysterectomy) years; 53%, 43%, and 37%, respectively, were black. Cronbach's alphas for the UFS-QOL-Hysterectomy questionnaire at 6 months ranged from 0.70 to 0.96 and from 0.66 to 0.95 at 12 months. Effect sizes ranged from 1.23 to 2.55, indicating that the UFS-QOL-Hysterectomy questionnaire was highly responsive. CONCLUSIONS: The UFS-QOL-Hysterectomy questionnaire is a valid and reliable patient-reported outcome measure of uterine fibroid treatment with hysterectomy and can be used in conjunction with the UFS-QOL questionnaire to compare patient-reported outcomes across treatments.

Evaluation of the Sexual Desire Relationship Distress Scale (SDRDS) in women with hypoactive sexual desire disorder.

INTRODUCTION: The Sexual Desire Relationship Distress Scale (SDRDS) was developed to address the need for a patient-reported outcome (PRO) measure of sexual distress associated with hypoactive sexual desire disorder (HSDD). The SDRDS is a 17-item PRO that includes items related to personal distress and distress related to relationship with partner. AIM: The aim of this article was to evaluate the psychometric properties of the SDRDS among women with HSDD. METHODS: Pre- and post-menopausal women with HSDD or with no sexual dysfunction completed the SDRDS, Sexual Activity Questions, Female Sexual Distress Scale-Revised (FSDS-R), and desire domain of the Female Sexual Function Index (FSFI) at baseline and 2 and 4 weeks later. MAIN OUTCOME MEASURES: The main outcome measures of this article were item performance, internal consistency, test-retest reliability, construct validity, known groups validity, and responsiveness of the SDRDS. RESULTS: Data from 260 women were analyzed: 101 in each of the pre- and post-menopausal HSDD groups and 29 in each of the pre- and post-menopausal control groups. No differences emerged between pre- and post-menopausal women. Least-squares mean (±standard errors [SE]) SDRDS score was higher in women with HSDD than in women with no sexual dysfunction (43.1 ± 0.9 vs. 6.1 ± 1.7; P < 0.0001), supporting known groups validity. Individual item scores correlated with total scores (r = 0.7-0.9; P < 0.0001). Internal consistency was high, with a Cronbach's alpha of 0.973 at baseline. Test-retest reliability was good, with an intraclass correlation coefficient of 0.89. SDRDS scores correlated strongly with other measures of sexual distress and sexual function including the FSDS-R and FSFI desire domain items. Preliminary analyses suggested that the SDRDS was sensitive to changes in clinical status. CONCLUSIONS: The SDRDS provides a comprehensive and reliable assessment of distress due to decreased sexual desire in women with HSDD and may be a useful measure of treatment effects in clinical trials in women with this condition.

Further validation of the uterine fibroid symptom and quality-of-life questionnaire.

OBJECTIVE: To further examine the reliability, validity and responsiveness of the uterine fibroid symptom and quality-of-life (UFS-QOL) questionnaire among women with and without uterine fibroids. METHODS: A multicenter, non-randomized, prospective study was conducted with women undergoing treatment for uterine fibroids (fibroid treatment group [FTG]) and normal controls (normal control group [NCG]). Women in the FTG were recruited when they were scheduled for treatment; women in the NCG were recruited during their annual exam. Participants completed the UFS-QOL and a short form 36 health survey (SF-36) at enrollment and at 6 and 12 months. Descriptive statistics, Cronbach's alpha, Spearman's correlations, t tests, and general linear models were used to analyze the internal consistency and test-retest reliability, concurrent and discriminant validity, and responsiveness of the UFS-QOL. RESULTS: There were 89 NCG and 234 FTG women who completed the study. Mean age was 43.1 years for FTG and 40.8 for NCG (P < 0.001). The FTG reported significantly greater symptom severity and worse health-related quality of life (HRQL) than the NCG (all UFS-QOL subscales P < 0.001). The UFS-QOL subscales were significantly correlated in the expected direction and magnitude with each SF-36 subscale in the FTG, indicating acceptable concurrent validity. Cronbach's alphas were 0.73 to 0.97, reflecting adequate internal consistency. Each UFS-QOL subscale was responsive to changes after treatment in the FTG with effect sizes ranging between 1.1 and -2.35. The UFS-QOL remained stable in the NCG during the 1 year follow-up. CONCLUSION: The UFS-QOL is a valid and reliable measure to assess symptoms and HRQL in women with uterine fibroids and is highly responsive to treatment-related changes.

Racial differences in the prevalence of overactive bladder in the United States from the epidemiology of LUTS (EpiLUTS) study.

OBJECTIVES: To estimate the prevalence of overactive bladder (OAB) in men and women in the United States (US) to determine whether there were racial differences. METHODS: This was a secondary analysis of data from the EpiLUTS (Epidemiology of Lower Urinary Tract Symptoms) survey, an Internet-based cross-sectional, population-representative epidemiologic survey conducted in the US, UK, and Sweden. These analyses were limited to the data of men and women aged 40 and older from the US. The presence of OAB was defined as experiencing urinary urgency or urinary urgency incontinence. Case definitions of OAB symptoms were categorized as occurring at least "sometimes." Prevalence rates of OAB were estimated by race. Logistic regression analyses were conducted for each gender to examine the role of race on OAB status, controlling for risk factors and comorbid conditions. RESULTS: The response rate in the US was 59.6%. A total of 9237 men and 10,407 women self-identified their race and were included in the analytic sample. The prevalence of OAB at least "sometimes" ranged from 26% in Asian men to 33% in African American men. Similarly, the prevalence of OAB at least "sometimes" was lowest in Asian women (27%) and highest in African American women (46%). Race was predictive of OAB in men but not for women. CONCLUSIONS: The prevalence of OAB ranged from 26-33% across races for men and from 27-46% across races for women. African American and Hispanic race is predictive of OAB for men but not for women.

Establishing the content validity of the King's Health Questionnaire in men and women with overactive bladder in the US.

BACKGROUND: Overactive bladder (OAB) consists of the symptoms of urinary urgency (with or without urgency incontinence) and increased urinary frequency and nocturia. As OAB is defined by symptoms, the patient is the best source of information for assessing the impact of the condition on health-related quality of life (HR-QOL). This assessment can be conducted through the use of valid patient-reported questionnaires, meaning the questionnaire has demonstrated content validity, among other acceptable psychometric properties. The aim of this study was to evaluate the content validity of the King's Health Questionnaire (KHQ) in patients with OAB in the US. METHODS: Men and women with continent or incontinent OAB were recruited from a clinical research site in the US. Participants completed the KHQ and were then asked about the instructions, items, and response options. Data were analyzed descriptively and qualitatively. RESULTS: A total of 24 participants (18 women, 6 men; mean [± SD] age 59.0 ± 11.1 years) with OAB were interviewed and provided feedback on the KHQ. Participants reported that overall, the KHQ covers the key aspects in which OAB impacts patients' daily lives. Most KHQ items and response options were acceptable and understandable to the participants; however, a few minor issues were noted. In item 3, shopping was not considered by some participants to be a household task, while shopping and cleaning were not relevant to some of the men. Two sets of items ('limit social life' and 'limit ability to see/visit friends' and 'bladder problem affect sleep' and 'feel worn out or tired') were perceived as redundant, while 'depressed' (item 12) and 'anxious or nervous' (item 13) were perceived by some participants as too intense. Some participants were unsure if the intended meaning of 'change your underclothes when they get wet' was about changing wet underwear or frequency of incontinence episodes. CONCLUSION: The KHQ demonstrated content validity and can be considered a relevant and appropriate tool to assess the impact of OAB on HR-QOL in men and women in the US.

Major symptom score utility index for patients with acute rhinosinusitis.

BACKGROUND: Evaluation of acute rhinosinusitis treatment effectiveness is based on patient-reported relief of symptoms. This study was designed to develop a multiattribute utility scoring algorithm for the Major Symptom Score (MSS) and secondarily to evaluate the psychometric characteristics (i.e., validity and responsiveness) of the MSS Utility Index (MSSUI). METHODS: Adult patients with acute rhinosinusitis were recruited for this longitudinal observational study through primary care and specialist physician offices. One hundred ninety patients participated in a preference elicitation exercise for MSS health states. Resulting preference data were used to generate a utility scoring algorithm for the MSS. Participants completed the MSS and 20-Question Sino-Nasal Outcome Test (SNOT-20) at baseline and completed the MSS twice daily for 15 days via daily diary. On days 7 and 15, participants completed the MSS, SNOT-20, and Overall Treatment Effect scale and were evaluated by physicians via the Physician Global Improvement Scale (PGIS). RESULTS: At baseline, the mean ± SD. MSSUI score was 0.51 ± 0.17 and was negatively correlated with SNOT-20 scores (r = -0.58; p < 0.001). Days 2-8 average MSSUI scores were negatively correlated with day 7 SNOT-20 (r = -0.46; p < 0.001) and PGIS (r = -0.22; p < 0.001) scores; whereas days 9-15 average MSSUI scores were inversely related to day 15 SNOT-20 (r = -0.40; p < 0.001) and PGIS (r = -0.32, p < 0.001) scores. Mean MSSUI scores improved from baseline with effect sizes at days 7 and 15 of 0.82 and 1.20, respectively. CONCLUSION: The MSSUI represents an acceptable and psychometrically sound patient-reported end point for clinical trials comparing treatments for acute rhinosinusitis.

The ability of the general male public to assess their suitability to take 50-mg sildenafil: an assessment of the comprehension of patient information materials via internet survey.

INTRODUCTION: Erectile dysfunction (ED) is the most common male sexual dysfunction and has a negative impact on masculinity and self-esteem. Phosphodiesterase type 5 inhibitors, including sildenafil, are the first-line treatment option for ED. Providing appropriate information regarding suitability for using sildenafil is important. AIM: The purpose of this study was to assess whether a broad spectrum of men could appropriately evaluate their suitability for 50-mg sildenafil after reviewing patient information materials. MAIN OUTCOME MEASURES: Patient information (Pack) on appropriate use of 50-mg sildenafil and patient information leaflet (PIL), a Web survey including demographics, self-assessed suitability for sildenafil use, and suitability screener. METHODS: A randomly selected, population-representative Web-based panel of males in the UK was recruited for this study. Eligible men answered a brief sociodemographic questionnaire and then were presented with the Pack. If a participant desired additional information, he could also review the PIL. The participants then rated the Pack and PIL (if reviewed), self-assessed their suitability for sildenafil use, and completed a previously validated screener for suitability. RESULTS: A total of 1,275 men aged 40 and above were included in these analyses; the mean age was 57.8 ± 9.9 years. A total of 1,054 men reported ED; 517 men (40.5%) deemed themselves suitable for sildenafil; 504 men (39.6%) deemed themselves unsuitable; and 254 (19.9%) were unsure. The concordance rate between screener-assessed suitability and self-assessed suitability was 70.9% (95% confidence interval [CI] = 68.1-73.7%). When accounting for men who would not take sildenafil even though they were suitable or would seek additional information from a healthcare professional prior to using sildenafil, the concordance rate was 84.2% (95% CI = 82.2-86.2%). CONCLUSION: The results of this study suggest that men in the general population are capable of using written sildenafil patient education materials to accurately assess their suitability for treatment with 50-mg sildenafil.

Validation of the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) in age-related macular degeneration.

PURPOSE: Patient-reported measures of visual function are increasingly incorporated into clinical trials of new treatments for age-related macular degeneration (AMD). Limited information is available regarding the associations between distance visual acuity (VA), reading speed, or contrast sensitivity and the National Eye Institute Visual Function Questionnaire-25 (NEI VFQ-25) subscales judged relevant to these measures. This study's objective was to evaluate such associations along with questions on restricted activity days. METHODS: This cross-sectional study was conducted in patients with clinical diagnoses of neovascular AMD. Patient-reported outcome measures included the NEI VFQ-25 and restricted activity days. Clinical assessments included best-corrected visual acuity (BCVA), reading speed, and contrast sensitivity. The better-seeing eye was defined based on the BCVA of each patient. Psychometric properties of the NEI VFQ-25 were examined; analyses a priori focused on the Near Activities, Distance Activities, and Vision-Specific Dependency subscales. RESULTS: The final study group included 92 participants (mean age, 78 years). Cronbach's α for the subscales ranged from 0.67 to 0.92. The NEI VFQ-25 overall composite, Near Activities, Distance Activities, and Vision-Specific Dependency scores were correlated with BCVA (r = -0.48 to -0.54, all P < 0.0001), reading speed (r = 0.43 to 0.56, all P < 0.0001), and contrast sensitivity (r = -0.39 to -0.46, all P < 0.001) of the better-seeing eye and with restricted activity days (r = -0.52 to -0.55, all P < 0.0001). CONCLUSIONS: This study provides additional evidence supporting the validity of the NEI VFQ-25 in neovascular AMD patients by demonstrating correlations with a spectrum of vision measurements and a daily function measure.

Validation of the urinary sensation scale (USS).

AIM: The purpose of this study was to assess the validity of the Urinary Sensation Scale (USS) in men with overactive bladder and voiding symptoms (OAB-LUTS) and women with overactive bladder (OAB). METHODS: Data from two OAB clinical trials of tolterodine were used. The USS, a 5-point scale, assesses the amount of urinary urgency associated with each urination. Three methods to calculate the USS are: mean urgency (Mean USS); mode urgency (Mode USS); and sum urgency (sum USS). The validity and responsiveness of the scoring methods was assessed using Spearman's correlations, general linear models, and effect sizes. RESULTS: Data from 650 men (Study 1) and 413 women (Study 2) were analyzed. Mean age was 65.2 (men) and 47.8 (women); 70% were Caucasian in both studies. Correlations of USS scores with bladder diary variables were small to moderate and higher among Sum USS than Mean USS (r=0.02-0.64). Correlations among the USS and patient-reported outcomes (PROs) were again small to moderate and higher with Sum USS (r=0.05-0.41). Both the Mean USS and Sum USS significantly discriminated (all P<0.001) among all bladder diary variables (except nocturia and UUI in men) when grouped as improved/not improved as well as by the PROs. Effect sizes for men and women, respectively, were -0.52 and -1.09 for Mean USS and -0.72 and -1.36 for Sum USS. CONCLUSION: The USS is a valid and highly responsive measure of urinary urgency in men with OAB-LUTS and women with OAB.
