Introduction The Prevention Guide for Leakage and Peristomal Skin Complications (PSCs) aims to advance holistic and structured preventive strategies in the management of leakage and PSCs. The Prevention Guide builds on the well-established Risk Factor Model for leakage and PSCs to provide a clinical tool linking systematic identification of risk factors to potential consequences and actionable mitigating interventions for the healthcare professionals (HCP) to consider.

Aim To translate the Risk Factor Model into a practical Prevention Guide for leakage and PSCs and evaluate the resulting tools, the bedside tool and the supporting learning resources, for clinical use.

Methods Through close collaboration with experienced stoma care nurses and clinical stoma care experts, the Prevention Guide was developed into an interactive PDF (iPDF) bedside tool, and supporting learning resources for e-learning, and a library of bite-sized videos. Quantitative pilot testing by stoma care nurses and qualitative reviews by clinical stoma care experts assessed the relevance and effectiveness of the Prevention Guide tools.

Results The Prevention Guide iPDF can be used as a decision-support tool in routine stoma care. The e-learning materials provide engaging structured modules that support the learner to implement a preventive approach. The video library features clear and concise bite-sized video explainers to be used for training, or for quickly brushing up on relevant knowledge regarding particular risk factors.

Conclusion All three tools have been evaluated by SCNs and were identified as useful tools for facilitating systematic patient assessment, enhancing documentation and providing an educational resource. Overall, the Prevention Guide helps to apply a systematic approach, linking problem identification for leakage and PSCs with corresponding targeted interventions.

Introduction Convex ostomy baseplates are designed to help minimise the risk of leakage and support the maintenance of peristomal skin health. Their performance is defined by five key characteristics: depth, slope, tension location, compressibility and flexibility. The adhesive component further plays a role in ensuring a secure and comfortable seal.

Aim The aim is to translate technical parameters that define convexity into practical clinical guidance, illustrating how these characteristics inform product selection and support optimal patient outcomes.

Methods This article synthesises current evidence and definitions of convexity parameters and integrates them with clinical reflections from two experienced stoma care nurses. Two real-world clinical cases are presented to demonstrate the practical application of convexity principles in postoperative stoma management.

Results Across the two cases, clinicians applied the five convexity parameters together with adhesive considerations to address challenges such as uneven abdominal contours, firm or bending abdominal walls, peristomal folds, mucocutaneous dehiscence and risks of leakage. In both scenarios, tailored convex product selection supported secure sealing and protected peristomal skin.

Conclusion Understanding the clinical relevance of convexity characteristics and adhesive performance is essential for effective product selection in stoma care. Individualised product selection based on patient-specific needs enables clinicians to optimise fit, maintain peristomal skin health and improve clinical outcomes.

Aims To investigate effects of SenSura Mio Convex Soft on stoma-leakage and leakage-related quality of life (QoL).

Methods The study was an interventional, single-arm, open-label, multicentre trial conducted in Great Britain, the Netherlands, Norway and USA. The sample comprised individuals with leakage-issues when using flat baseplates. Participants used their own flat pouching system in a 2-week baseline period and subsequently SenSura Mio Convex Soft for 12 weeks. The primary endpoint was leakage area underneath the baseplate-adhesive. Secondary outcomes were leakage incidents outside the baseplate and leakage-related QoL using the validated Ostomy Leak Impact (OLI) tool, which consists of three domains capturing the impact of leakage on emotional aspects, engagement in usual and social activities and ability to cope and being in control. Primary comparisons between 12-week data with SenSura Mio Convex Soft and baseline flat baseplates were evaluated using mixed repeated measures models and a logistic regression model for correlated data.

Results Statistical analyses included 74 participants (Intention-to-treat population). After 12 weeks, use of SenSura Mio Convex Soft resulted in less leakage underneath the baseplate-adhesive than with flat pouching systems (estimated mean difference=−2.4 cm squared; P=0.001). Participants experienced fewer incidents of leakage outside the baseplate when using SenSura Mio Convex Soft (with 2.2% of the baseplates) versus flat pouching systems (7.0%) (P<0.001). Participants also reported significant improvements in all three domains of the OLI tool. Adverse events were comparable between the baseline and intervention periods, mainly affecting the peristomal skin.

Conclusions Study findings indicate that using SenSura Mio Convex Soft resulted in less leakage underneath the baseplate, fewer soiling incidents and higher leakage-related QoL compared to using flat pouching systems.

The study was registered on ClinicalTrials.gov (ID-NR: NCT02517541).
