Table 2 ICU mortality rates and hand hygiene compliance before, during, and after COVID-19 pandemic periods

	ICU patient-days	Death (No.)	Incidence Rate (per 1000 ICU patient-days) (%)	Hand hygiene compliance (%)
Period-1 (23 September 2018 to 20 March 2019)	3594	117	32.56	36.5
Period-2 (21 March 2019 to 22 September 2019)	3769	86	22.82	50
Period-3 (23 September 2019 to 20March 2020)	3438	77	22.39	57
Period-4 (21 March 2020 to 21 September 2020)	2898	154	53.19	23
Period-5 (22 September 2020 to 19 March 2021)	3502	89	25.42	27
Period- 6 (21 March 2021 to 22 September 2020)	3777	155	41.06	47
Period- 7 (23 September 2021 to 20 March 2022)	3085	170	55.12	46

The results of the Spearman's correlation coefficient indicate a moderate inverse relationship of −0.571 between the incidence rate of mortality and hand hygiene compliance, although this result is not statistically significant (p = 0.180)
