Following publication of the original article [1], the authors reported below errors.

1) In the results of the article, ‘recognized that the level of nurse staffing (58.3%) as well as availability of PPE (53.6%) was adequate. One-third of all the nurses (65.5%) stated that EHR was inconvenient’ should be ‘recognized that the level of nurse staffing (58.3%) as well as availability of PPE (53.6%) was inappropriate. One-third of all the nurses (65.5%) stated that EHR was convenient’.

  2) In Table 1, there have been inaccuracies in the values attributed to 'Appropriate' and 'Inappropriate' in the 'Level of nurse staffing,' 'Availability of PPE,' and 'Convenience of EHR' variables. Consequently, 'Appropriate' for 'Level of nurse staffing' should be adjusted from '98 (58.3)' to '70 (41.7),' and 'Inappropriate' should be rectified from '70 (41.7)' to '98 (58.3).' Similarly, for the 'Availability of PPE' variable, 'Appropriate' should be amended from '90 (53.6)' to '78 (46.4),' and 'Inappropriate' should be changed from '78 (46.4)' to '90 (53.6).' Furthermore, the 'Convenience of EHR' variable necessitates correction, with 'Convenience' being revised from '58 (34.5)' to '110 (65.5)' and 'Inconvenience' being altered from '110 (65.5)' to '58 (34.5).'

3) In Table 2, there has been an inadvertent interchange of values between 'Appropriate' and 'Inappropriate' in the 'Level of nurse staffing,' 'Availability of PPE,' and 'Convenience of EHR' variables. Consequently, 'Appropriate' for 'Level of nurse staffing' should be rectified from “18.71 ± 17.59’ to '11.64 ± 14.14', and 'Inappropriate' should be amended from '11.64 ± 14.14' to '18.71 ± 17.59'. Additionally, the 't' value should be revised from '2.78' to '-2.78.'

Similarly, for the 'Availability of PPE' variable, 'Appropriate' should be modified from '17.40 ± 16.45' to '13.88 ± 16.61', and 'Inappropriate' should be adjusted from '13.88 ± 16.61' to '17.40 ± 16.45' The 't' value should also be changed from '1.38' to '-1.38.'

Furthermore, the 'Convenience of EHR' variable necessitates correction, with 'Convenience' being revised from '19.83 ± 18.33' to '13.63 ± 15.21', and 'Inconvenience' should be altered from '13.63 ± 15.21' to '19.83 ± 18.33'. Additionally, the 't' value should be corrected from '2.34' to '-2.34.'
