About this trial
Individuals living with an intestinal or urinary stoma frequently report disturbed sleep. Night-time pouch filling and leakage, odour and gas concerns, restricted sleeping positions, peristomal skin problems and the need for night-time pouch emptying interrupt sleep, while anxiety, depressive symptoms, altered body image and social withdrawal add to this burden. Poor sleep in this population has been associated with reduced quality of life and impaired daytime functioning; however, most of the available evidence is cross-sectional and based exclusively on self-reported measures. Nursing interventions that specifically target sleep in people with a stoma are few, generally consist of a single component, and have rarely been tested in randomised designs or alongside objective sleep measurement.
This trial evaluates an Artificial Intelligence-Supported Multimodal Nursing Intervention (AI-MNI) developed to improve sleep quality in adults living with a stoma. The intervention was designed in line with the Medical Research Council framework for complex interventions and is delivered over four weeks through the institutional web-based learning management system. It comprises five structured modules: stoma care and night-time comfort; sleep hygiene and night routine; psychological wellbeing and relaxation techniques; body image, self-esteem and sexual health; and physical activity and daily energy management. Each module combines written material, video, visual guides, checklists and short knowledge checks. A rule-based chatbot embedded in the platform supports participants by prioritising content, suggesting review of relevant material and responding to questions within a pre-approved educational content set; it does not provide diagnosis, treatment advice or clinical decision support. All content was evaluated for content validity by an expert panel before implementation.
The study is a two-arm, parallel-group randomised controlled trial conducted in the stomatherapy unit of a university hospital. Forty-two adults (21 per group) with a colostomy, ileostomy or urostomy of at least three months' duration and a Pittsburgh Sleep Quality Index (PSQI) global score greater than 5 will be allocated in a 1:1 ratio using permuted block randomisation with variable block sizes, stratified by sex and stoma type. Allocation is concealed through a central, password-protected web-based system, and statistical analyses are performed by a statistician blinded to group codes. The intervention group receives AI-MNI in addition to standard care; the control group receives standard care alone and is offered access to the programme after the final assessment (delayed-access design). Assessments are conducted at baseline (T0), at the first month (T1) and at the third month (T2). The primary outcome is the change in PSQI global score from baseline to the first month, with the third-month assessment used to examine whether any improvement is maintained. Secondary outcomes are objective sleep parameters (total sleep time, sleep efficiency, sleep stage indicators and sleep onset latency) recorded with a consumer wrist-worn device on three consecutive nights at each assessment point, and stoma-specific quality of life. Module completion, session duration and level of interaction are reported as process outcomes. Analyses follow the intention-to-treat principle and are based primarily on linear mixed-effects models.

AI-MNI: Artificial Intelligence-Supported Multimodal Nursing Intervention
BehavioralFour-week, module-based digital nursing intervention delivered through the institutional web-based learning management system, in addition to standard stomatherapy care. Five modules address stoma care and night-time comfort; sleep hygiene and night routine; psychological wellbeing and relaxation techniques; body image, self-esteem and sexual health; and physical activity and daily energy management. Each module combines written material, video, visual guides, checklists and short knowledge checks, and all modules are available throughout the four-week period. A rule-based chatbot embedded in the platform prioritises content, suggests review of relevant material and answers questions within a pre-approved educational content set; it does not provide diagnosis, treatment advice or clinical decision support. Content validity was established with an expert panel, and platform use (module completion, session duration, interaction) is recorded as a process outcome.
Treatment groups
Trial outcomes
Primary outcomes
Change in sleep quality (Pittsburgh Sleep Quality Index)
PSQI global score, range 0-21; higher scores indicate poorer sleep quality. Change from baseline to the end of the first month.
Secondary outcomes
Sleep quality at 3 months (Pittsburgh Sleep Quality Index)
PSQI global score, range 0-21; higher scores indicate poorer sleep quality. Change from baseline to the third month, assessing maintenance of the effect.
Total sleep time measured with a wrist-worn device
Total sleep time in minutes per night, recorded with a consumer wrist-worn device over three consecutive nights at each assessment point and averaged across the three nights. Higher values indicate longer sleep duration.
Sleep efficiency measured with a wrist-worn device
Sleep efficiency, calculated as total sleep time divided by time in bed and expressed as a percentage, recorded with a consumer wrist-worn device over three consecutive nights at each assessment point and averaged across the three nights. Higher values indicate better sleep continuity.
Sleep onset latency measured with a wrist-worn device
Sleep onset latency in minutes, defined as the interval between bedtime and sleep onset, recorded with a consumer wrist-worn device over three consecutive nights at each assessment point and averaged across the three nights. Lower values indicate faster sleep onset.
Other outcomes
Usability of the digital intervention and chatbot
Perceived usability assessed in the intervention group only with the AI-MNI Usability and Functionality Form, a 14-item, 5-point Likert-type instrument adapted from the System Usability Scale and the Chatbot Usability Questionnaire, covering comprehensibility, ease of use, technical performance, supportiveness and overall satisfaction. Total score ranges from 14 to 70; higher scores indicate better perceived usability.
Module completion rate
Proportion of the five intervention modules completed by each participant during the four-week intervention period, expressed as a percentage and recorded automatically by the learning management system. Assessed in the intervention group only.
Total time spent on the digital platform
Cumulative session duration in minutes on the learning management system during the four-week intervention period, recorded automatically by the platform. Assessed in the intervention group only.
Number of chatbot interactions
Total number of participant-initiated chatbot interactions recorded automatically by the platform during the four-week intervention period. Assessed in the intervention group only.
