Metrics and management: Two unresolved problems on the pathway to health care-associated infection elimination.

Surveillance and management of health care-associated infections (HAIs) has traditionally relied on analyses of outcome data to elucidate trends in HAI incidence, discover host or treatment risk factors, and facilitate comparisons of HAI rates within and among licensed providers or facilities. This paper explores residual gaps and shortcomings associated with outcome reporting and possible sources of bias that may invalidate intra- and interfacility comparisons. As an alternative to outcome surveillance and reporting, real-time process monitoring and control is proposed. To address the need for uncompromising conformity with preventive measures, the concepts of social entropy, authority, responsibility, and accountability are explored and linked to process control at the bedside.
