Healthcare professionals' intentions to use wiki-based reminders to promote best practices in trauma care: a survey protocol

Abstract

BackgroundHealthcare professionals are increasingly using wikis as collaborative tools to create, synthesize, share, and disseminate knowledge in healthcare. Because wikis depend on collaborators to keep content up-to-date, healthcare professionals who use wikis must adopt behaviors that foster this collaboration. This protocol describes the methods we will use to develop and test the metrological qualities of a questionnaire that will assess healthcare professionals' intentions and the determinants of those intentions to use wiki-based reminders that promote best practices in trauma care.MethodsUsing the Theory of Planned Behavior, we will conduct semi-structured interviews of healthcare professionals to identify salient beliefs that may affect their future use of wikis. These beliefs will inform our questionnaire on intended behavior. A test-retest of the survey will verify the questionnaire's stability over time. We will interview 50 healthcare professionals (25 physicians and 25 allied health professionals) working in the emergency departments of three trauma centers in Quebec, Canada. We will analyze the content of the interviews and construct and pilot a questionnaire. We will then test the revised questionnaire with 30 healthcare professionals (15 physicians and 15 allied health professionals) and retest it two weeks later. We will assess the internal consistency of the questionnaire constructs using Cronbach's alpha coefficients and determine their stability with the intra-class correlation (ICC).DiscussionTo our knowledge, this study will be the first to develop and test a theory-based survey that measures healthcare professionals' intentions to use a wiki-based intervention. This study will identify professionals' salient beliefs qualitatively and will quantify the psychometric capacities of the questionnaire based on those beliefs.

“…A study entitled " to implement and evaluate the impact of an elective evidence-based medicine (EBM) course on student performance during advanced pharmacy practice experiences (APPE)", using a Pre-and post tests found that students improved on 83% of the core evidence-based medicine concepts evaluated (Bookstaver et al , 2011). Archambault et al (2010) Surveyed 50 healthcare professionals (25 physicians and 25 allied health professionals) working in the emergency departments of three trauma centers in Quebec, Canada using interview to find out their intention on using wiki to promote reminder in cancer care.…”

Emergency medicine residents' beliefs about contributing to a Google DocsTM presentation: a survey protocol

“…Even though a similar questionnaire has been validated in previous research projects, 34,45 a focus group of three residents having access to the Google Docs TM slideshow will validate the semi-structured questionnaire and clinical vignette. This focus group will confirm participants' general understanding of the questions and of the behaviour described in the vignette.…”

“…In addition to the present study, our research team is surveying healthcare professionals' intention to use wiki-based reminders in trauma care. 34 Furthermore, other studies using the TPB have identified the beliefs of healthcare professionals about their intention to complete an internetbased continuing medical education programme. 45 Together, these studies will generate results that will help develop interventions to increase healthcare professionals' contributions to internet-based collective writing projects, to be tested in a future trial.…”

“…25 To apply the theory, academics employ methods and tools that have been replicated many times. [34][35][36][37][38][39][40][41][42][43] According to the TPB, intention is influenced by three constructs: attitude, subjective norm and perceived behavioural control. Attitude ('Aact' in Figure 1) is defined as an actor's beliefs about the consequences (the advantages and disadvantages) of a behaviour.…”
