Objective:To systematically summarize, describe, and evaluate the evidence related to convex baseplates use in adult ostomy patients through an evidence map, in order to identify research gaps and future directions.Methods:A systematic search was conducted in Chinese and English databases, including China National Knowledge Infrastructure, Wanfang Data, VIP, and PubMed, and others, from database inception to September 2024. Randomized controlled trials and quasi-experimental studies on convex baseplates use in adult ostomy patients were included. Literature quality was assessed using the Cochrane Handbook 5.1.0 bias risk assessment tool and the critical appraisal tool for quasi-experimental studies from the Joanna Briggs Institute Centre for Evidence-Based Healthcare. Based on the PICO principle [participant (P) , intervention (I) , comparison (C) , outcome (O) ] , an evidence mapping coding system was extracted and developed by integrating relevant guidelines and consensus. Data extraction and coding were performed using EPPI-Reviewer software, and key evidence characteristics and literature quality were presented using bubble charts.Results:A total of eight randomized controlled trials and six quasi-experimental studies were included. Most of the 14 studies had a high risk of bias. The target populations for interventions were divided into two categories: prevention and treatment. The main complications involved stoma skin-mucosal separation, stoma peristomal dermatitis, and stoma height issues. The main outcome measures included baseplate seal integrity, wound healing, complication rates, clinical symptoms, adverse events, patient acceptance, and quality of life.Conclusions:Most of the studies on convex baseplates has focused on enterostomy patients. The majority of studies have a high risk of bias, and the number of studies is limited. Further clarification is needed on the selection criteria for convex baseplates with different characteristics, and the clinical application effects of convex baseplates urgently need further evaluation.

Objective:To investigate the current status of convex baseplate selection and use among clinical nurses.Methods:A convenience sampling method was employed to survey 1 873 nurses from 180 hospitals across China between November and December 2024 using a general information questionnaire and a self-designed questionnaire on convex baseplate selection and use. A total of 1 873 questionnaires were distributed, and 1 860 valid responses were collected, yielding a response rate of 99.31% (1 860/1 873) .Results:Among the 1 860 nurses, 88.98% (1 655/1 860) had access to convex baseplates in clinical practice. However, only 8.82% (146/1 655) used them immediately postoperatively, and only 4.53% (75/1 655) chose convex baseplates without considering any product features. The five common clinical indications for convex baseplate use included stoma retraction (96.62%, 1 599/1 655) , peristomal skin folds or depressions (96.56%, 1 598/1 655) , flush stomas (80.12%, 1 326/1 655) , leakage (70.03%, 1 159/1 655) , and abdominal laxity (66.89%, 1 107/1 655) . Common contraindications for use included peristomal varicose veins (77.46%, 1 282/1 655) , peristoma pressure injuries (75.35%, 1 247/1 655) , stoma prolapse (74.50%, 1 233/1 655) , parastomal hernia (72.87%, 1 206/1 655) , and pyoderma gangrenosum (67.01%, 1 109/1 655) . Key assessment areas when selecting convex baseplates included the stoma itself (97.28%, 1 610/1 655) , peristomal skin (96.50%, 1 597/1 655) , abdominal wall contour (95.41%, 1 579/1 655) , excretion patterns (87.37%, 1 446/1 655) , and previous convex baseplate use (82.36%, 1 363/1 655) . Measures commonly used by nurses to enhance adhesion included the use of stoma belts (95.29%, 1 577/1 655) , barrier rings or paste (94.80%, 1 569/1 655) , smoothing peristomal skin folds (90.57%, 1 499/1 655) , advising patients to limit bending (82.96%, 1 373/1 655) , and abdominal binders (57.28%, 948/1 655) .Conclusions:The clinical application of convex baseplates requires further promotion. Nursing administrators should strengthen training on the selection, characteristics, and indications of convex baseplates, with particular emphasis on the understanding of the five key product features.

In June 2022, the Journal of Wound, Ostomy and Continence Nursing published the use of a convex pouching system in the postoperative period: a national consensus (hereinafter referred to as the "consensus") . The consensus recommends the use of convex ostomy products immediately after surgery and within the first six months following ostomy formation. It also establishes principles for selecting the most appropriate ostomy product for patients. This article interprets the background and significance of the consensus and highlights its key points, aiming to provide a reference for the standardized use of convex ostomy products postoperatively.

The classification of stoma skin barriers varies based on their specific features. The curvature design of convex skin barriers provides a secure and effective seal for patients with flat, retracted stomas or peristomal skin folds. The secure sealing ability of convex skin barriers is attributed to several critical structural components. Although convex skin barriers offer many clinical advantages, there is currently no unified standard for measuring their characteristics, resulting in confusion among healthcare professionals when selecting stoma care products. To address this issue, the 2021 International Stoma Care Expert Meeting proposed the Expert Consensus on Characteristics of Convex Skin Barriers and Clinical Application, which clearly defines five essential properties and clinical application guidelines for convex barriers. However, as most consensus contributors are from Europe and North America, its applicability in Chinese healthcare settings may be limited. Therefore, this paper provides a detailed interpretation of the five characteristics and clinical application statements of convex skin barriers, aiming to offer practical guidance to clinical nurses in selecting appropriate convex products and managing stoma-related complications.

Stoma refers to the channel established by surgery to excrete the excreta in the body, which changes the excretion mode of patients, and has a serious impact on the physiological, psychological, spiritual, social and other aspects of patients. The World Council of Enterostomal Therapists released International Ostomy Guideline (Second Edition) in 2020, covering four aspects, including the education and scope of practice, holistic approach to care, preoperative nursing needs and postoperative nursing needs, and a total of 15 recommendations. This article focuses on the interpretation of eight recommendations on the two aspects of preoperative and postoperative nursing needs, with a view to promoting the reform of clinical practice and providing evidence-based basis for clinical nurses. At the same time, it is suggested that clinical nurses should make targeted transformation according to specific clinical situations to improve the quality of clinical nursing.

With the development of medical technology, the survival rate of cancer patients continues to improve, and the number of stoma patients is increasing day by day. Self-management refers to patients monitoring and managing their own diseases to maintain and improve physical health. Good self-management ability can enhance patient treatment compliance, reduce the incidence of stoma and surrounding complications, improve health outcomes, and raise patient quality of life. This article reviews the research progress on self-management of stoma patients, with the aim of providing reference for research on self-management of stoma patients.
