Prevalence of New Delhi metallo-beta-lactamase (NDM) increased over time in certain vSNFs. A, Time window of when facilities were tested for each survey. Observance of NDM+ carbapenem-resistant Enterobacterales in vSNFs and LTACHs in survey 1 led to targeted follow-up surveys (2, 3, and 4) in these facilities. B, Proportion of NDM and Klebsiella pneumoniae carbapenemase–positive samples across surveys and facilities. vSNF O was not included as there was uneven sampling across surveys. ICUs are not shown in panel B because of very low prevalence (see Table 1). Abbreviations: ICU, intensive care unit; LTACH, long-term acute care hospital; vSNF, ventilator-capable skilled nursing facility.
