The authors review empirical literature from 1980 to 2005 on relationships between healthcare organizations' finances and quality of care. They found only 16 studies of this topic that employed statistical methods. This research indicates cumulatively that expenses, fiscal margin, and asset and liability management all affect healthcare outcome quality. There is less evidence about how organizational finance factors affect structural or process quality, and there is no information about how structural or process quality mediates between finances and outcomes. The authors note what patterns have emerged from previous studies and make specific suggestions about what future research is necessary and why.
