OBJECTIVE:: To estimate whether prolapse severity is a major contributor to urinary incontinence severity, as measured by validated incontinence questionnaires. METHODS:: We analyzed data from two large female stress urinary incontinence (SUI) surgical cohorts: the Stress Incontinence Surgical Treatment Efficacy Trial (SISTEr) study (N=655) and the subsequent Trial of Mid-Urethral Slings (TOMUS) study (N=597). All participants completed a standardized baseline assessment including validated measures of symptom severity, quality of life, objective measures of urine loss (Urogenital Distress Inventory [UDI], Medical, Epidemiologic, and Social Aspects of Aging questionnaire, Incontinence Impact Questionnaire, and pad test), as well as the Pelvic Organ Prolapse Quantification assessment. Groups were compared using the chi; test (categorical measures) or the one-way analysis of variance (continuous measures). Statistical significance was defined as P<.05. RESULTS:: The SISTEr and TOMUS samples were similar for many variables including age (52 and 53 years, respectively), nulliparity (9% and 12%), prior urinary incontinence (UI) surgery (14% and 13%), and prior hysterectomy (31% and 28%), but other differences necessitated separate analysis of the two cohorts. There was not a statistically significant difference in UDI scores according to prolapse stage in either study population. Patients with prior surgery for pelvic organ prolapse and SUI had more incontinence symptoms and were more bothered by their UI regardless of prolapse stage. CONCLUSION:: Prolapse stage is not strongly or consistently associated with incontinence severity in women who select surgical treatment of SUI. Prior pelvic organ prolapse and UI surgery is associated with worse UI severity and bother. CLINICAL TRIAL REGISTRATION:: ClinicalTrials.gov, www.clinicaltrials.gov, NCT00064662 and NCT00325039.

ABSTRACT: BACKGROUND: Increasingly, the context of healthcare organizations such as hospitals is viewed as having the potential to influence the use of new knowledge. However, the mechanisms by which organizational context influences evidence-based practices are not well understood. Current measures of organizational context have not always been developed using a theory-informed approach, often lack construct clarity and generally have modest psychometric properties. This paper presents the development and initial psychometric assessment of the Alberta Context Tool (ACT), an eight dimension measure of organizational context for healthcare settings. METHODS: Three principals guided the development of the ACT: substantive theory, brevity, and modifiability. The Promoting Action on Research Implementation in Health Services (PARiHS) framework and related literature were used to guide selection of items in the ACT. The ACT was required to be brief enough to be tolerated in busy and resource stretched work settings and to assess concepts of organizational context that were potentially modifiable. The English version of the ACT was completed by 764 nurses (752 valid responses) working in seven Canadian pediatric care hospitals as part of its initial validation. Cronbach's alpha, exploratory factor analysis, analysis of variance, and tests of association were used to assess instrument reliability and validity. RESULTS: Factor analysis indicated a 13-factor solution (accounting for 59.26% of the variance in 'organizational context'). The composition of the factors was similar to those originally conceptualized. Cronbach's alpha for the 13 factors ranged from .54 to .91 with 4 factors performing below the commonly accepted alpha cut off of .70. Bivariate associations between instrumental research utilization levels and the ACT's 13 factors were statistically significant at the 5% level for 12 of the 13 factors. Each factor also showed a trend of increasing mean score ranging from the lowest level to the highest level of instrumental research use, indicating construct validity. CONCLUSIONS: To date, no completely satisfactory measures of organizational context are available for use in healthcare. The ACT assesses several core domains to provide a comprehensive account of organizational context in healthcare settings. The tool's strengths are its brevity (allowing it to be completed in busy healthcare settings) and its focus on dimensions of organizational context that are modifiable. Refinements of the instrument in acute, long term care, and home care settings are ongoing.

A model of anxiety that emphasizes a single common pathology across diagnostic categories is gaining support and influencing nosological and treatment approaches of anxiety disorders. As research in this area continues to grow, a need exists for an assessment tool of the theorized single anxiety pathology that is unbiased toward any particular anxiety diagnosis. The Anxiety Disorder Diagnostic Questionnaire (ADDQ) was developed as a screening tool for the presence of clinical fear and anxiety irrespective of diagnoses. It is a brief four-section index developed to assess fear, anxiety/worry, escape/avoidance behaviors, physiological symptoms, and associated distress and interference. The ADDQ was tested for reliability and validity in two samples: 146 undergraduate students who were given the ADDQ along with a variety of other commonly-used measures of anxiety and 94 outpatients representing a mix of diagnoses (28.2% panic disorder with or without agoraphobia, 44.6% social anxiety disorder, 20.7% generalized anxiety disorder, 3.3% anxiety disorder not otherwise specified, 2.1% obsessive-compulsive disorder, and 1.1% posttraumatic stress disorder). Internal consistency of the instrument was strong, and a one- or two-factor solution was found to be the best fit to the data. Convergent and discriminant validity was also demonstrated. Data from those clinical participants who completed a manualized cognitive-behavioral treatment program indicated a very strong concordance between change on the ADDQ and change in clinician severity ratings from a structured diagnostic interview. The findings offer support for the psychometric validity of the ADDQ in both clinical and nonclinical populations.

This paper presents a novel method for cell positioning on a substrate which combines the optical quality of glass and the cell-repelling property of fluoropolymers. The process employs plasma lithography, which utilizes the high-resolution patterning of photolithography along with the versatility of the plasma polymerization. When mammalian cells were grown over these substrates, they avoided the fluoropolymer regions and grew almost exclusively within the exposed glass areas (windows). The patterned surface reproduces the initial design of the mask, offering the possibility to control cell distances and interactions with a versatile arrangement whilst keeping the optical quality of glass for microscopy observation, in particular, when a pristine substrate in needed. This approach opens up possibilities for analysis of biological processes, such as studying cell interactions, with the integration of optical or electrical sensors.

OBJECTIVES To explore whether instruction in fluid management resulted in changes in fluid intake and incontinence over a 10-week study period in women with urinary urge incontinence (UUI), as fluid management might be a critical strategy in treating this condition. PATIENTS AND METHODS In the 'Behaviour Enhances Drug Reduction of Incontinence' trial, women with predominant UUI were randomized to daily treatment with tolterodine or tolterodine combined with behavioural therapies, among which were individualized instructions on fluid management. Patients in both groups received general fluid management instructions, while in the drug + behaviour arm, those with excessive urine output (>2.1 L/day) had additional individualized instruction during each of four study visits to learn behavioural strategies. Variables measured at baseline and at 10 weeks were type of incontinence, using the Medical, Epidemiological, and Social Aspects of Aging questionnaire, severity of incontinence by number of incontinence episodes based on a 7-day diary, number of voids/24 h (F(24)), urgency rating, 24-h fluid intake (I(24)) and 24-h volume voided (V(24)), volume average (V(avg)), pad use, bothersomeness of UUI (Urogenital Distress Inventory and Overactive Bladder questionnaire), and quality of life (Incontinence Impact Questionnaire-7 and Short-Form-12). RESULTS Leakage episodes/24 h, V(24), I(24) and average urgency ratings all significantly decreased from baseline to 10 weeks (P < 0.001 for each). V(avg) increased (P < 0.001), as did voids/L intake (P = 0.01). None of the changes in diary variable outcomes differed by treatment group after accounting for these changes between baseline and 10 weeks. In a multivariable model, treatment group was not associated with change in V(24) from baseline to 10 weeks (P = 0.81), but the difference in the number of accidents/diary day, F(24), I(24), and average voids/day each were positively related with the change in V(24)(P < 0.001 for each). Patients had a response to fluid management instructions; the decrease in the percentage of women with a V(24) of >2.1 L between baseline and follow-up was statistically significant (P = 0.01 McNemar's test). CONCLUSION General fluid instructions can contribute to the reduction in UUI symptoms for women taking anticholinergic medications, but additional individualized instructions along with other behavioural therapies did little to further improve the outcome.

Objective. To define patient safety event (PSE) learning response and to provide preliminary validation of a measure of PSE learning response. Data Sources. Ten focus groups with front-line staff and managers, an expert panel, and cross-sectional survey data from patient safety officers in 54 general acute hospitals. Study Design. A mixed methods study to define a measure of learning responses to patient safety failures that is rooted in theory, expert knowledge, and organizational practice realities. Extraction Methods. Learning response items developed from the literature were modified and validated in front-line staff and manager focus groups and by an expert panel and second group of external experts. Actual learning responses gleaned from survey data were examined using exploratory factor analyses and reliability analysis. Principal Findings. Unique learning response items were identified for minor, moderate, major events, and major near misses by an expert panel. A two-factor model of major event learning response was identified (factor 1=event analysis, factor 2=dissemination/communication of learnings). Organizations engage in greater learning responses following major events than less severe events and, for major events, organizations engage in more factor 1 responses than factor 2 learning responses. Conclusions. Eleven to 13 items can measure learning responses to PSEs of differing severity. The items are feasible, grounded in theory, and reflect expert opinion as well as practice setting realities. The items have the potential for use to assess current practice in organizations and set future improvement goals.

ABSTRACT: BACKGROUND: While there is a growing awareness of the importance of organizational context (or the work environment/setting) to successful knowledge translation, and successful knowledge translation to better patient, provider (staff), and system outcomes, little empirical evidence supports these assumptions. Further, little is known about the factors that enhance knowledge translation and better outcomes in residential long-term care facilities, where care has been shown to be suboptimal. The project described in this protocol is one of the two main projects of the larger five-year Translating Research in Elder Care (TREC) program. AIMS: The purpose of this project is to establish the magnitude of the effect of organizational context on knowledge translation, and subsequently on resident, staff (unregulated, regulated, and managerial) and system outcomes in long-term care facilities in the three Canadian Prairie Provinces (Alberta, Saskatchewan, Manitoba). METHODS: This study protocol describes the details of a multi-level -- including provinces, regions, facilities, units within facilities, and individuals who receive care (residents) or work (staff) in facilities -- and longitudinal (five-year) research project. A stratified random sample of 36 residential long-term care facilities (30 urban and 6 rural) from the Canadian Prairie Provinces will comprise the sample. Caregivers and care managers within these facilities will be asked to complete the TREC survey -- a suite of survey instruments designed to assess organizational context and related factors hypothesized to be important to successful knowledge translation and to achieving better resident, staff, and system outcomes. Facility and unit level data will be collected using standardized data collection forms, and resident outcomes using the Resident Assessment Instrument-Minimum Data Set version 2.0 instrument. A variety of analytic techniques will be employed including descriptive analyses, psychometric analyses, multi-level modeling, and mixed-method analyses. DISCUSSION: Three key challenging areas associated with conducting this project are discussed: sampling, participant recruitment, and sample retention; survey administration (with unregulated caregivers); and the provision of a stable set of study definitions to guide the project.

There is little agreement in the literature as to what types of patient safety events (PSEs) should be the focus for learning, change and improvement, and we lack clear and universally accepted definitions of error. In particular, the way front-line providers or managers understand and categorize different types of errors, adverse events and near misses and the kinds of events this audience believes to be valuable for learning are not well understood. Focus groups of front-line providers, managers and patient safety officers were used to explore how people in healthcare organizations understand and categorize different types of PSEs in the context of bringing about learning from such events. A typology of PSEs was developed from the focus group data and then mailed, along with a short questionnaire, to focus group participants for member checking and validation. Four themes emerged from our data:(1) incidence study categories are problematic for those working in organizations;(2) preventable events should be the focus for learning;(3) near misses are an important but complex category, differentiated based on harm potential and proximity to patients;(4) staff disagree on whether events causing severe harm or events with harm potential are most valuable for learning. A typology of PSEs based on these themes and checked by focus group participants indicates that staff and their managers divide events into simple categories of minor and major events, which are differentiated based on harm or harm potential. Confusion surrounding patient safety terminology detracts from the abilities of providers to talk about and reflect on a range of PSEs, and from opportunities to enhance learning, reduce event reoccurrence and improve patient safety at the point of care.

ABSTRACT: BACKGROUND: The knowledge translation field is undermined by two interrelated gaps -- underdevelopment of the science and limited use of research in health services and health systems decision making. The importance of context in theory development and successful translation of knowledge has been identified in past research. Additionally, examination of knowledge translation in the long-term care (LTC) sector has been seriously neglected, despite the fact that aging is increasingly identified as a priority area in health and health services research. AIMS: The aims of this study are: to build knowledge translation theory about the role of organizational context in influencing knowledge use in LTC settings and among regulated and unregulated caregivers, to pilot knowledge translation interventions, and to contribute to enhanced use of new knowledge in LTC. DESIGN: This is a multi-level and longitudinal program of research comprising two main interrelated projects and a series of pilot studies. An integrated mixed method design will be used, including sequential and simultaneous phases to enable the projects to complement and inform one another. Inferences drawn from the quantitative and qualitative analyses will be merged to create meta-inferences. Outcomes Outcomes will include contributions to (knowledge translation) theory development, progress toward resolution of major conceptual issues in the field, progress toward resolution of methodological problems in the field, and advances in the design of effective knowledge translation strategies. Importantly, a better understanding of the contextual influences on knowledge use in LTC will contribute to improving outcomes for residents and providers in LTC settings.

Interest in the assessment of quality of life in the anxiety disorders is growing. The present study examined quality of life impairments in individuals with generalized anxiety disorder (GAD), social phobia, and panic disorder. Results showed that individuals with these disorders reported less satisfaction with their quality of life than non-anxious adults in the community. However, the degree of quality of life impairment is similar across these three disorders. Additionally, comorbid depression, but not anxiety, was found to negatively impact quality of life in these individuals. Finally, diagnostic symptom severity was not found to influence quality of life, indicating that subjective measures of quality of life offer unique information on the effects of anxiety disorders.
