TABLE 2. Comparison of personal protective equipment (PPE) use and patient source control reported by health care personnel (HCP) during higher-risk* SARS-CoV-2 exposures in acute- and ambulatory-care settings and congregate living and long-term-care settings — Minnesota, March 6–July 11, 2020^†.

PPE and exposure characteristic	No. (%)		p-value§
	Acute- and ambulatory-care setting exposures (n = 913)	Congregate living/long-term care setting exposures (n = 905)
HCP mask	757 (82.9)	565 (62.4)	<0.001
HCP respirator	65 (7.1)	46 (5.1)	0.07
HCP eye protection	240 (26.3)	140 (15.5)	<0.001
Patient/Resident mask	119 (13.0)	59 (6.5)	<0.001
HCP no PPE	92 (10.1)	131 (14.5)	0.004
HCP PPE breach	142 (15.6)	101 (11.2)	0.006
HCP in the same room when an AGP¶ was performed	167 (18.3)	34 (3.8)	<0.001

Abbreviation: AGP = aerosol-generating procedure.

* High-risk exposure category focused on eyes, nose, and mouth as primary routes of transmission and HCP in this category lack protection of those areas. Medium-risk exposure category included potential for transmission by contamination of HCP hands or body during patient care activities. On May 19, CDC’s risk assessment was updated to include a single higher-risk exposure category. For this analysis, medium-, high- and higher-risk exposures were combined as “higher-risk exposures.” Higher-risk exposures assessed by Minnesota Department of Health included nonpatient care interactions (e.g., coworkers, social contacts, and from household contacts).

^† The denominator includes all higher-risk HCP exposures, not the number of individual HCP exposed.

^§ Calculated with chi-squared test.

^¶ AGP included open suctioning of airway secretions, sputum induction, cardiopulmonary resuscitation, endotracheal intubation and extubation, noninvasive positive pressure ventilation (e.g., bilevel positive airway pressure and continuous positive airway pressure), bronchoscopy, manual ventilation; nebulizer was considered an AGP through March 26, 2020.
