Abstract
The objectives of this study were to establish additional content validation data for proposed stomal and peristomal complications interventions and to identify optimal interventions for the specified complications based on experts' clinical judgment.
Following pilot testing of the researcher-designed instrument, the survey was mailed to 1000 systematically randomly selected expert WOC nurses via a national mailing to a representative sample of participants who identified in their WOCN Society description as having ostomy certification and/or clinical expertise. Two hundred eighty-one nurses returned the survey, comprising a response rate of 28%.
A cross-sectional, quantitative descriptive design with qualitative components was used for this study. Respondents were asked to quantify degree of validity (relevance or appropriateness) of the survey's stated stomal and peristomal complications interventions. They were asked to rank interventions for each stomal and peristomal complication for being first-line (most preferred), second-line, and third-line treatment. Hand-written qualitative comments of the participants were transcribed and analyzed, and themes were derived.
On a scale of 1 to 4, the mean score for all interventions was 3.47 ± 0.29 (relevant/very relevant, mean ± SD). The overall survey's Content Validity Index was 0.84 out of 1.00. Some items had lower mean scores and content validity index scores, especially peristomal interventions. Ranking of most preferred treatments revealed clearly preferred approaches in some clinical situations and some less so. Qualitative analysis of participants' comments about each stomal and peristomal complication intervention and about the whole instrument and research process was conducted generating positive and negative themes.
The proposed stomal and peristomal interventions were rated as generally valid substantiating results of our earlier study. The ranking of most preferred treatments for stomal and peristomal complications provides, to the authors' knowledge, the world's first research support for prioritized approaches and evidence-based practice in ostomy care.
