The goal of this effort is to support prevention of psychological health problems through innovation in mobile personal health assessment and self-help intervention (SHI). For the U.S. military, we are developing and evaluating a field-deployable personalized application, PHIT for DutyTM, to help build resilience in healthy troops and support prevention in(More)
PURPOSE The aim of the study is to estimate incidence rates of occupational blood exposure by route of exposure (needlesticks; cuts from sharp objects; mucous membrane exposures to the eyes, nose, or mouth; bites; and blood contact with nonintact skin) in US and California paramedics. METHODS A mail survey was conducted in a national probability sample of(More)
BACKGROUND This survey was conducted to provide national incidence rates and risk factors for exposure to blood among paramedics. The present analysis assesses reporting of exposures to employers. METHODS A questionnaire was mailed in 2002-2003 to a national sample of paramedics selected using a two-stage design. Information on exposure reporting was(More)
OBJECTIVE The purpose of this analysis is to present incidence rates of exposure to blood among paramedics in the United States by selected variables and to compare all percutaneous exposure rates among different types of healthcare workers. METHODS A survey on blood exposure was mailed in 2002-2003 to a national sample of paramedics. Results for(More)
With the emergence of mobile health (mHealth) apps, there is a growing demand for better tools for developing and evaluating mobile health interventions. Recently we developed the Personal Health Intervention Toolkit (PHIT), a software framework which eases app implementation and facilitates scientific evaluation. PHIT integrates self-report and(More)
BACKGROUND To reduce the incidence of phlebotomy-related percutaneous injuries (PIs), factors that contribute to these injuries must be identified. This study examined institutional phlebotomy practices, policies, perceptions, and culture to identify facilitators and barriers that appear to have the greatest impact in preventing injuries. METHODS During(More)
BACKGROUND Paramedics are at risk for human immunodeficiency virus, hepatitis B virus, and hepatitis C virus infection from occupational blood exposure. This study examined how often paramedics are provided with personal protective equipment (PPE), sharps containers, and selected safety devices by their employers; the frequency with which paramedics use(More)
BACKGROUND Home care/hospice nurses may be at elevated risk of blood exposure because of the nature of their work and work environment. However, little is known about the incidence of blood exposure in this population. METHODS A mail survey (n = 1,473) was conducted among home care/hospice nurses in North Carolina in 2006. RESULTS The adjusted response(More)
OBJECTIVES Formative research can serve as a means of obtaining important information for designing an epidemiologic study, but descriptions of this approach in the epidemiologic literature are lacking. The objective of this paper is to describe the use of three formative research techniques in designing a survey of home care and hospice nurses. METHODS(More)
