Interpretation of total score: 7: High risk: clean after each case/event/procedure and at least twice per day, clean additionally as required; 4–6: Moderate Risk : clean at least once daily, clean additionally as required (e.g. Gross soiling), 2–3 : Low risk: clean according to a fixed scheduled, clean additionally as required (e.g. Gross soiling)
