A picture is worth a thousand words: exploring the roles of caregivers and the home environment of ventricular assist device patients

Content Validity of the Left Ventricular Assist Device Bathing Assessment

Many institutions recommend modified bathing techniques for individuals with left ventricular assist devices (LVADs) due to infection risk. Although these techniques may be challenging for patients, there currently is no assessment to evaluate these skills and whether intervention programs have been successful. This article describes the development and content validation of the LVAD Bathing Assessment. The content validity index (CVI) process was used to determine the relevance of assessment items. Modified Kappa indices were calculated to account for the possibility of chance agreement among raters. Eight content validity experts rated each assessment item and provided feedback. The overall assessment and 44 of 47 individual items had excellent content validity (scale-level CVI [S-CVI] = 0.97; item-level CVI [I-CVI] > 0.78). Minor revisions were made based on feedback. Creation of an LVAD bathing assessment may improve care by identifying safety risks that may cause infection. Further studies for construct validation and reliability testing are needed.

Can you picture it? Photo elicitation in qualitative cardiovascular health research

Photo elicitation offers novel opportunities to augment the qualitative research toolbox. The use of photographs can enrich connections with participants, and empower them to be creative and engaged to communicate their insights, priorities, and perspectives. There is growing evidence of the effective use of photo elicitation in health research, with emerging interest in the cardiovascular community. Careful study planning, including attention to equipment, participant training, photograph selection, data collection, and ethical consideration, is essential. Detailed reporting of the study design and rationale for use of photographs, conceptual thinking underpinnings, elicitation process, and analytical plan contribute to strengthening the methodological approach.
