Data for: "Clean Frontline: a stepped wedge, cluster-randomised, trial testing the impact of a multi-component training intervention on microbiological cleanliness in Cambodian referral hospitals" – Data Codebook

Persistent identifier

10.17037/DATA.00004857

Description

Disinfection of near-patient hospital surfaces is essential to prevent the occurrence of Hospital Acquired Infection (HAI). The CLEAN Frontline study investigated the impact of training to change environmental hygiene on wards across thirteen hospitals in Cambodia. Data was recorded at three levels - hospital, ward, and sample level.

Data codebook

The dataset is comprised of three tables that record information at the hospital, ward, and sample level.
