Table 2.

The impact of independent variables measured in period 1 on SARS-CoV-2 infection or a positive COVID-19 case definition in period 2.

Period 1 variables	Period 2: outcome reached^*% (n)	Difference [S.E.]	p-value
PPE insufficient availability - [n = 107]	61.7 (66)	−9.9 [5.3]	0.065
PPE sufficient availability - [n = 446]	51.8 (231)	−9.9 [5.3]	0.065
insufficient PPE training - [n = 310]	60.6 (188)	−14.2 [4.0]	<0.001
sufficient PPE training - [n = 304]	46.4 (141)	−14.2 [4.0]	<0.001
incorrect PPE selection - [n = 134]	56.0 (75)	+1.8 [5.4]	0.737
correct PPE selection - [n = 218]	57.8 (126)	+1.8 [5.4]	0.737
insufficient cohorting - [n = 243]	61.7 (150)	−13.3 [4.0]	0.001
sufficient cohorting - [n = 374]	48.4 (181)	−13.3 [4.0]	0.001
insufficient screening availability - [n = 164]	50.6 (83)	+4.1 [4.6]	0.363
sufficient screening availability - [n = 453]	54.7 (248)	+4.1 [4.6]	0.363
