Content validation and usability of a chatbot of guidelines for wound dressing.

INTRODUCTION: The growing demand from patients with wounds from various causes has significantly challenged primary care nurses. A chatbot, with duly validated evidence-based content, can assist both nurses and patients in managing care. This work describes the development process of such a chatbot (BOTCURATIVO) that aims to help the treatment of wounds by non-specialists, by giving guidelines about the recommended wound dressing procedures for each type of wound. METHOD: Methodological research was carried out in three phases. The first one corresponded to the validation of the script's content through a panel of enterostomal therapist nurses, who evaluated the domains and items of the chatbot script. Data analysis was performed using the Content Validity Index by individual level and scale level (≥ 0.80). To verify the agreement between the evaluators, the Kappa test was used. In the second phase, the chatbot was developed, using GOOGLE'S DIALOGFLOW platform. Finally, in the third phase, the chatbot's usability was analyzed using the System Usability Scale (SUS), by 17 users, 8 of them being patients with chronic wounds, 5 caregivers of people with acute and chronic wounds and 4 nurses. RESULTS: The established domains achieved excellent suitability, relevance and representativeness criteria, all above 90 %; the content validity index per level of scale reached 0.97 and 0.82 by the methods of average and universal agreement, respectively, with excellent agreement between the evaluators (Kappa value: 0.83). The global usability score was 80.1. CONCLUSION: The script developed and incorporated into the chatbot prototype achieved a satisfactory level of content validity. The usability of the chatbot was considered good, adding to the credibility of the device.

Assessment instruments for lower urinary tract dysfunction in children: Symptoms, characteristics and psychometric properties.

INTRODUCTION: The use of instruments to assess symptoms of the lower urinary tract has increased mainly when it comes to pediatric urology. The search for a validated and reliable one for use in clinical practice should be a concern of the professionals involved in the care of these children. OBJECTIVE: The aim of this study was to analyze the assessment instruments for lower urinary tract dysfunction in children regarding: symptoms, characteristics and psychometric properties. STUDY DESIGN: PubMed and Latin American and Caribbean Literature in Health Sciences databases were searched. The PICO strategy was used to construct the research question and bibliographic search. Keywords included voiding disorders, LUTS, Child, Surveys and Questionnaires. RESULTS: Nine articles were identified. The construct observed by all instruments was bladder dysfunction and seven instruments also assessed bowel dysfunction. Thirty different events were addressed. In eight instruments the respondents are the parents. The age of the target population ranged from three to eighteen years and regarding the number of items, an average of 21.8 items was observed. Six instruments showed good results of reliability and four presented good results of accuracy. CONCLUSIONS: The instruments included a wide range of symptoms related to dysfunction. Only two reported all validation and reliability tests, however six instruments showed good reliability results, making them eligible for the cross-cultural adaptation and validation process for use in countries other than those of the instrument's origin.
