title: Methodological issues in nurse staffing research.
abstract: The purpose of this article is to identify and describe four issues in nurse staffing research that must be addressed before the evidence base for the relationship between nurse staffing and quality of care can be said to be theoretically and empirically sufficient. The issues are the need to build well-developed theory, use valid and reliable databases, appropriate risk-adjustment systems, and address issues of causal inference in nonexperimental research.
