Introduction Colorectal stomas are prevalent in surgical wards and demand careful medical attention, particularly in stoma management. Junior doctors play a vital role in this care, but their limited exposure and training may hinder their ability, impacting patient care. Given the dearth of literature, we aimed to assess junior doctors' stoma care knowledge and the efficacy of a specialized teaching course in boosting their confidence and skills. Methods The research, conducted at the West Suffolk Hospital NHS Trust in the UK, engaged 60 junior doctors, predominantly from Foundation Year 1 and Year 2, from August 2021 to December 2022. To ensure effective management and assessment, participants were divided into four groups, each comprising 15 doctors. A pivotal aspect of the study was implementing a structured stoma teaching series delivered by a panel of seasoned surgical experts. This series, conducted every Friday for three weeks, comprehensively covered all facets of stoma care. Both before and after the teaching series, assessments were administered to measure the impact of this educational intervention on the participants' understanding of stomas. The study meticulously adhered to ethical guidelines, with all participants providing informed consent, and measures were implemented to guarantee anonymity, thus safeguarding the privacy and confidentiality of all individuals involved. The primary objective of this investigation was to evaluate the efficacy of the stoma teaching series in augmenting the knowledge and comprehension of stomas among junior doctors. The findings of this study hold significant potential in guiding healthcare professionals toward developing more efficacious stoma education programs, ultimately leading to improved patient care outcomes. Results The study involved 60 junior doctors categorized into four groups from August 2021 to December 2022. It aimed to assess their understanding of colorectal stomas, focusing on complications and their knowledge about stoma appliances and care nurses. A questionnaire was used to evaluate their knowledge in these areas at the start of their surgical rotation, which showed significant knowledge gaps among participants. Of the 60 participants, 48 (80%) expressed slight or no confidence in basic stoma care, while 54 (90%) admitted unfamiliar with managing stoma complications. Astonishingly, all 60 (100%) participants lacked awareness of fundamental stoma care concepts. Significant improvements were observed following a comprehensive stoma teaching series covering basic stoma knowledge, its complications and management, and practical stoma care. Feedback from the course revealed positive outcomes, with 54 (87%) doctors feeling confident or very confident in basic stoma knowledge and 48 (80%) reporting increased familiarity with managing stoma complications. Remarkably, all 60 (100%) doctors indicated comfort with stoma care concepts after the sessions. Participants emphasized the course's value in medical education and professional development, citing enhanced practical skills such as communication and teamwork. Conclusion Our study revealed junior doctors' limited stoma knowledge, emphasizing the need for a dedicated teaching program that significantly improves their understanding.Focused stoma education is vital for junior doctors to deliver optimal patient care, necessitating hospitals to promote awareness for improved patient outcomes.
