Variable definitions
| Type | Variable | Definition |
|---|---|---|
| Impact | Cleanliness (Aerobic Colony Counts—ACC) |
Binary (< 2.5 cfu/cm2 = clean; ≥ 2.5 cfu/cm2 = not clean) Categorical (0; > 0 to < 2.5; 2.5 to < 12; 12 to < 40; 40+) |
| Impact | Cleanliness (S. aureus) | Binary: presence or absence of S. aureus |
| Process outcome | Cleaning action (gel dots) | Binary (cleaning performed: gel dot completely removed; failure: gel dot not removed or only partially removed) |
| Outcome predictor | Ward type | Categorical (labour ward, postnatal vaginal deliveries, post-natal c-section deliveries, neonatal ward OR KMC ward) |
| Outcome predictor | Hospital | Categorical (1, 2, 3) |
| Outcome predictor | Bed occupancy |
Occupancy is the number of patients divided by the number of beds in that specific ward [Note: Number of patients was collected during each visit. For labour ward only it refers to the number of patients present during last shift] |
| Study characteristic | Shift type | Categorical (gel dots applied either morning, afternoon or night) |
| Study characteristic | Bed frame/mattress | Binary (mattress or bed sampled) |
| Context | Water availability | Binary (whether water is flowing from at least one access point: yes, no) |
| Context | Chlorine availability | Binary (whether chlorine is available in the central store and within the expiry date: yes, no) |
