Background Incontinence-associated dermatitis (IAD) is a common and preventable condition in older adults with incontinence. People suffering from IAD are usually disdained by individuals, professionals, policy makers, caregivers, and communities. To date, a standard guideline on IAD management is still lacking in Hong Kong. Thus, it is important to develop an evidence-based incontinence-associated guideline for older adults with incontinence in Hong Kong. Objectives This thesis aims to identify the best available evidence for skin care management for people suffering from IAD and to develop an evidence-based practice guideline to reduce the incidence of IAD. Methods Review of literature related to the management of IAD was performed on electronic database according to the inclusion and exclusion criteria. The inclusion criteria included randomized controlled trials and quasi-experiments. In addition, the studies should be in English and should contain the full text. The target participants should be patients aged 60 or above who are suffering from urinary, fecal, or double incontinence and are using diapers. Participants should include cognitively impaired patients, as well as those experiencing skin redness or injury at the perineal or thigh area resulting from incontinence. All non-medical regimens, skin care products, and absorbent diapers or pads designed for managing incontinence related to skin breakdown in older adults with incontinence were also included. The quality of the literatures was assessed according to the checklist provided by the Scottish Intercollegiate Guidelines Network (SIGN) (2011), and the data obtained from the reviewed papers were extracted and summarized in eight tables of evidence. Then, an IAD skin care management guideline was developed based on these pieces of evidence. The transferability, the feasibility, and the cost-benefit ratio of implementing the proposed IAD skin care management guideline were assessed. In addition, the communication plan, the evaluation plan, and the pilot study of the proposed guideline were included in this thesis. Results The proposed IAD skin care management guideline is a structured skin care management program for older adults with incontinence. With the help of the proposed guideline, registered nurses could provide a standard IAD skin care program based on best available evidence. Moreover, reviewed studies show that the IAD severity score, which is used to evaluate the prevalence of IAD, can be reduced by 47 % by implementing the proposed guideline. In addition, a systematic communication plan with stakeholders, an evaluation plan, and a pilot study were designed to examine the feasibility and the transferability of the proposed guideline. Patient outcome is the main outcome measure, and this measure is directly related to the IAD severity score. In this study, the IAD severity score was reduced, indicating that the proposed IAD skin care management program is effective, feasible, and cost-effective in the local setting. Conclusion The proposed skin care management guideline for caring for older adults with IAD was developed based on best available evidence. The prevalence of IAD is expected to be reduced after the implementation of this guideline. / published_or_final_version / Nursing Studies / Master / Master of Nursing
