The Green Maternity project: A midwife‐led initiative to promote correct waste segregation on an Australian postnatal ward

Abstract

AbstractAimsHealthcare waste production is a significant contributor to carbon emissions, negatively impacting the environment. Ineffective healthcare waste disposal results in greater measures to manage it which is costly to both the environment and healthcare organizations. This study aimed to improve waste management in a tertiary maternity hospital. Specifically, the impact of a midwife‐led intervention to improve waste segregation, staff knowledge and attitudes and waste management‐related costs was investigated.DesignA multi‐method study including pre‐ and post‐intervention staff waste management knowledge and attitude surveys and waste audits of bins located on the postnatal ward.MethodsThe intervention included education sessions, posters and signage by waste bins and monthly newsletters distributed throughout 2021 to raise staff awareness of correct waste segregation processes. Pre‐ and post‐intervention surveys were distributed in early 2021 and early 2022, respectively. The waste audits occurred on three occasions, January, July and December of 2021. The waste audit included total waste in kilograms (kg), waste in kg by segregation and identification of correct and incorrect segregation. Waste audit and quantitative staff survey data were analysed using descriptive statistics and chi square. Qualitative data from the staff surveys were analysed using content analysis.ResultsKnowledge and attitudes to waste management were similar across pre‐ and post‐intervention staff surveys. Knowledge of accurate allocation of specific items to waste streams was variable with errors identified in both the pre‐ and post‐surveys. Waste audit data showed reductions in clinical waste at each measurement, with a 71.2% decrease in clinical waste from baseline to the final audit. Accuracy of waste segregation also improved from the baseline to final audit, resulting in a 48% reduction in waste management costs.ConclusionThe midwife‐led initiative improved waste segregation and achieved the associated waste management cost reduction.ImpactA midwifery‐led initiative to address waste production and segregation on a maternity ward had a positive impact on waste segregation practices and associated waste management costs. The existence of change champions along with in‐service sessions, posters and newsletters to raise awareness of correct waste segregation resulted in a 71% reduction of incorrect items being placed in clinical waste bins. Challenges such as COVID‐19 pressures and workload made it difficult for midwives to engage in waste management education and effective waste segregation.Patient or Public ContributionNo patient or public contribution.What Does this Paper Contribute to the Wider Global Clinical Community?Implementing clinician‐led waste management interventions across hospital wards while addressing workload issues are likely to have significant cost benefits for organisations and minimise the environmental impacts of healthcare settings.
