Constructing the Vulvar Pain Assessment Questionnaire Inventory

The goals of this program of research were to examine the link between self-reported vulvar pain and clinical diagnoses, and to create a user-friendly assessment tool to aid in that process. These goals were undertaken through a series of four empirical studies (Chapters 2-6): one archival study, two online studies, and one study conducted in a Women’s Health clinic. In Chapter 2, the link between self-report and clinical diagnosis was confirmed by extracting data from multiple studies conducted in the Sexual Health Research Laboratory over the course of several years. We demonstrated the accuracy of diagnosis based on multiple factors, and explored the varied gynecological presentation of different diagnostic groups. Chapter 3 was based on an online study designed to create the Vulvar Pain Assessment Questionnaire (VPAQ) inventory. Following the construct validation approach, a large pool of potential items was created to capture a broad selection of vulvar pain symptoms. Nearly 300 participants completed the entire item pool, and a series of factor analyses were utilized to narrow down the items and create scales/subscales. Relationships were computed among subscales and validated scales to establish convergent and discriminant validity. Chapters 4 and 5 were conducted in the Department of Obstetrics & Gynecology at Oregon Health & Science University. The brief screening version of the VPAQ was employed with patients of the Program in Vulvar Health at the Center for Women’s Health. The accuracy and usefulness of the VPAQscreen was determined from the perspective of patients as well as their health care providers, and the treatment-seeking experiences of patients was explored. Finally, a second online study was conducted to confirm the factor structure, internal consistency, and test-retest reliability of the VPAQ inventory. The results presented in these chapters confirm the link between targeted questions and accurate diagnoses, and provide a guideline that is useful and accessible for providers and patients.

Challenges, Strengths and Opportunities Related to Implementing Comprehensive Evidence-Based Guidelines on Breast Cancer Survivorship Care by Primary Care Physicians and Nurse Practitioners in Southeastern Ontario

Background Many breast cancer survivors continue to have a broad range of physical and psychosocial problems after breast cancer treatment. As cancer centres move forward with earlier discharge of stable breast cancer survivors to primary care follow-up it is important that comprehensive evidence-based breast cancer survivorship care is implemented to effectively address these needs. Research suggests primary care providers are willing to provide breast cancer survivorship care but many lack the knowledge and confidence to provide evidence-based care. Purpose The overall purpose of this thesis was to determine the challenges, strengths and opportunities related to implementing comprehensive evidence-based breast cancer survivorship guidelines by primary care physicians and nurse practitioners in southeastern Ontario. Methods This mixed-methods research was conducted in three phases: (1) synthesis and appraisal of clinical practice guidelines relevant to provision of breast cancer survivorship care within the primary care practice setting; (2) a brief quantitative survey of primary care providers to determine actual practices related to provision of evidence-based breast cancer survivorship care; and (3) individual interviews with primary care providers about the challenges, strengths and opportunities related to provision of comprehensive evidence-based breast cancer survivorship care. Results and Conclusions In the first phase, a comprehensive clinical practice framework was created to guide provision of breast cancer survivorship care and consisted of a one-page checklist outlining breast cancer survivorship issues relevant to primary care, a three-page summary of key recommendations, and a one-page list of guideline sources. The second phase identified several knowledge and practice gaps, and it was determined that guideline implementation rates were higher for recommendations related to prevention and surveillance aspects of survivorship care and lowest related to screening for and management of long-term effects. The third phase identified three major challenges to providing breast cancer survivorship care: inconsistent educational preparation, provider anxieties, and primary care burden; and three major strengths or opportunities to facilitate implementation of survivorship care guidelines: tools and technology, empowering survivors, and optimizing nursing roles. A better understanding of these challenges, strengths and opportunities will inform development of targeted knowledge translation interventions to provide support and education to primary care providers.
