No. of Studies Reviewed/category 30 35 39

Types of Healthcare Facilities from which Study or Report Arose

Number and percent of studies for various MDROs by healthcare facility type.
Facility Type MDR-GNB MRSA VRE

α Variably described as university hospitals, medical school affiliated hospitals, VA teaching hospitals, and, to a much lesser extent, community teaching hospitals

Unit of Study for MDRO Control Efforts

LTCF 0 1 2
Region 0 2 1

β Includes intensive care units, burn units, dialysis units, hematology/oncology units, neonatal units, neonatal intensive care units, and, in a few instances, individual wards of a hospital

Nature of Study or Report on MDRO Control χ

Number of outbreak and non-outbreak studies for each of the 3 types of MDRO.
Nature of Study MDR-GNB MRSA VRE
Outbreak 22 19 28
Non-outbreak 8 16 11

χ Based on authors' description – if they called their experience an outbreak or not; authors vary in use of term so there is probable overlap between two categories
