Alarm therapy for nocturnal enuresis in children: A literature review

Nocturnal enuresis is a common childhood problem impacting the quality of life of children and families. Treatment with an enuresis alarm is recommended for 8-12 weeks by the International Children's Continence Society as first line management of monosymptomatic nocturnal enuresis. However, the effectiveness of alarm therapy varies between 80% and 45.9%. There is minimal evidence within the literature exploring the factors impacting this varying response to alarm therapy. Therefore, this literature review aims to explore factors that impact the effectiveness of the enuresis alarm as a treatment for nocturnal enuresis, in children aged 5-17 years. Literature searches were conducted on MEDLINE (Ovid), SCOPUS and CINAHL Databases. The PRISMA tool was used to report the data in the search strategy. The inclusion criteria of children aged 5 to 17 years was chosen based on International Children's Continence Society Guidelines. English language, academic journals and studies in the past 10 years were selected as additional inclusion criterion to identify the most recent, robust literature for the review. All 13 primary research articles were critiqued using the Caldwell Framework. Data were extracted and presented in table format highlighting study methodology, sample, duration of treatment, relevance to review topic and key findings. The findings highlight factors influencing the effectiveness of alarm therapy related to the impact on the child and family, heighten arousal to the alarm, the duration of therapy, age of child and the impact of overlearning. This review provides health professionals with an insight into strategies that may help children and their family to respond successfully to enuresis alarm treatment.
