This shows no change from the previous data point, 2011/12, when the indicator was introduced (the indicator is a score between 0 and 100, but not a percentage value, with higher score representing better outcomes). Since 2008, this level has fuctuated betwen 74% and 77%. For example, in the case of health care-acquired infections, the website explains that improvements can be achieved through measures including hand hygiene, hospital cleanliness, equipment decontamination and optimal antimicrobial prescribing. The data for this indicator, however, relate to 2011, and some of the other indicators are also based on old data, making them less useful.
