Surveillance of nosocomial infections

Surveillance for nosocomial infections is one of the most effective quality assurance outcome measurements of health care. To provide the most reliable data, organization is the key to reporting good data. Specific criteria must be defined, and where and how the necessary data is most readily available must be determined. Surveillance activity must be performed concurrently so that data can be reported in a timely manner and appropriate action can be taken if necessary. Reports must be designed in a concise and understandable manner so they are easily interpreted and can be effectively used. The method of data reporting must be analyzed, committees and individuals who need to evaluate the data must be identified, and any necessary action must be taken to ensure that data fit the evaluators' needs. The use of graphics to provide a clearer picture of consistent rates or problem areas should be evaluated.
