CLEAN Frontline: A Stepped Wedge Cluster Trial

Status Completed

Clinical Trial Summary

Environmental hygiene is a key component of infection prevention in healthcare, and a driver of healthcare associated infections. Staff who clean in many low resource countries receive no formal training on cleaning, waste disposal and linen handling. This issue has been execrated by the COVID-19 pandemic. The only recommended training on environmental hygiene for low resourced facilities, TEACH CLEAN, uses a training of trainers model. A selected cadre "champions" which in turn train their peers with responsibilities on environmental hygiene at the facility level. Early pilot data to test its effectiveness of this training package are very promising. The main objective is to evaluate the effectiveness of an environmental cleaning bundle to improve microbiological cleanliness in Cambodian hospitals. The latest TEACH CLEAN will be implemented across all hospitals (13) of three provinces in Cambodia. A stepped wedge randomised trial will be used to evaluate the effectiveness of TEACH CLEAN to improve microbiological cleanliness in Cambodian hospitals. All facilities will receive the intervention. Hospitals are arranged in groups of three or four based on the randomisation with staggered commencement dates of the intervention at four distinct time points. The design will include ten months of data collection. We expect one month gap between the training of champions and the training of staff at the facility level. The main outcome is microbiological cleanliness (<2.5 cfu/cm2 = clean ; ≥2.5 cfu/cm2 = not clean) measured using a non-specific agar on one side for measuring total Aerobic Colony Counts (ACC/cm2). With 30 sampling sites in each hospital and with a pre-training cleanliness proportion ranging from 30% to 50% will give us over 85% power to detect a 10% absolute post-intervention increase in cleanliness. Evidence from this trial will contribute to future policy and practice guidelines about hospital environmental hygiene and ultimately reduce healthcare associated infections. This would be the first randomised trial on environmental hygiene in low resource settings.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
