Cervical Intraepithelial Neoplasia Rates in British Columbia Women: A Population-Level Data Linkage Evaluation of the School-Based HPV Immunization Program.

BACKGROUND: To understand real-world human papillomavirus (HPV) vaccine impact, continuous evaluation using population-based data is critical. We evaluated the early impact of the school-based HPV immunization program on cervical dysplasia in women in British Columbia, Canada. METHODS: Data linkage was performed using records from provincial cervical screening and immunization registries. Precancerous outcomes were compared between unvaccinated and HPV-vaccinated women born 1994-2005. Incidence rate, relative rate (RR), and vaccine effectiveness (VE), using unadjusted and adjusted Poisson regression of cytology (HSIL) and histopathology (CIN2, CIN3, and CIN2+) outcomes, were compared across vaccination status groups. RESULTS: Women who received a complete series of vaccine on schedule between age 9 and 14 years had an adjusted RR = 0.42 (95% confidence interval [CI], 0.31-0.57) for CIN2+ over 7 years of follow-up compared to unvaccinated women, resulting in a VE of 57.9% (95% CI, 43.2%-69.0%). Adjusted RR for HSIL was 0.53 (95% CI, .43-.64), resulting in a VE of 47.1% (95% CI, 35.6%-56.7%). CONCLUSION: Women vaccinated against HPV have a lower incidence of cervical dysplasia compared to unvaccinated women. Immunization between 9 and 14 years of age should be encouraged. Continued program evaluation is important for measuring long-term population impact.

Examining the scope of public health nursing practice in sexually transmitted infection prevention and management: what do nurses do?

AIMS AND OBJECTIVES: To develop a more comprehensive understanding of the scope of public health nursing practice in the prevention and management of sexually transmitted infections and also to examine the public health nursing workforce in sexually transmitted infection care and the range of patient populations served. BACKGROUND: Sexually transmitted infections are increasing, widespread and remain a significant public health problem throughout the world. Although nurses are taking on expanded roles in sexually transmitted infection care, little is known about the scope of this practice. DESIGN: A cross-sectional descriptive study took place over 18 months (2009-2010). METHODS: Three hundred and fourteen eligible nurses completed a 62-item questionnaire. RESULTS: 93·6% of participants were women; 77·5% were baccalaureate prepared and 87·9% underwent continuing education in sexually transmitted infection care. Most spent 50% of their time in direct patient care. Women were the main care recipients (72·9%). Sexually transmitted infection care was one aspect of nurses' multifaceted public health roles accounting for 28% of overall work activities. Not all nurses were working to the full scope of their practice; 77·9% undertook health history assessment, and 79% conducted testing. CONCLUSION: This study is a comprehensive description of the scope of sexually transmitted infection nursing practice activities. It expands our understanding of sexually transmitted infection nursing practice among nurses working within an expanded scope and provides a baseline for future investigations. This description is situated within nursing competencies and best practices that may be used to develop, implement and evaluate models of sexually transmitted infection service delivery in other locales. CLINICAL PRACTICE RELEVANCE: Sexually transmitted infection nursing practice needs to be understood and investigated beyond health education and testing practices. The scope of practice is comprehensive and incorporates a full spectrum of care. Public health nurses are a critical entry point into the healthcare system and provide primary and preventative care and healthcare referrals. Models of nursing care need to support nurses working to their full scope, and associated barriers warrant further investigation.

STI service delivery in British Columbia, Canada; providers' views of their services to youth.

BACKGROUND: Little is known about service providers' knowledge, attitudes, and experiences in relation to the assessment, diagnosis, and treatment of individuals seeking care for sexually transmitted infections (STIs), and how they influence the delivery of services. The purpose of this study was to explore the perceptions of STI care providers and the ways they approached their practice. METHODS: We used a qualitative approach drawing on methods used in thematic analysis. Individual semi-structured in-depth interviews were conducted with 21 service providers delivering STI services in youth clinics, STI clinics, reproductive health clinics, and community public health units in British Columbia (BC), Canada. RESULTS: Service providers' descriptions of their activities and roles were shaped by a number of themes including specialization, scarcity, and maintaining the status quo. The analysis suggests that service providers perceive, at times, the delivery of STI care to be inefficient and inadequate. CONCLUSION: Findings from this study identify deficits in the delivery of STI services in BC. To understand these deficits, more research is needed to examine the larger health care structure within which service providers work, and how this structure not only informs and influences the delivery of services, but also how particular structural barriers impinge on and/or restrict practice.
