* Abbreviations used: HCW health care worker, IC infection control, MDR multidrug resistant, PPE personal protective equipment. The analyses in this table include 64/67 facilities, as 3 did not report sufficient data on TB cases; ^aThis can also be interpreted as an increase with 50 health care workers for each of the 5 years; ^bThis is not an erroneous duplication of the Odds ratio and confidence interval listed for presence of culture laboratory. Included were 25 centres with an MDR-TB ward and 25 centres with a culture laboratory (18 of which had both); 7 centres had no MDR-TB ward but a culture laboratory; 7 other centres had no culture laboratory but had an MDR-TB ward
