Correction to: Factors associated with post-traumatic stress disorder in nurses after directly caring for COVID-19 patients: a cross-sectional study (BMC Nursing, (2023), 22, 1, (282), 10.1186/s12912-023-01431-5)

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).' (Table presented.) Characteristics and PTSD (N = 168) Age (years) 31.47 ± 9.25 Below the median (< 28) 80 (47.6) Above the median (≥ 28) 88 (52.4) Work experience (years) 8.91 ± 9.53 Below the median (< 4) 83 (49.4) Above the median (≥ 4) 85 (50.6) Gender Male 6 (3.6) Female 162 (96.4) Marital status Unmarried 118 (70.2) Married 50 (29.8) Cohabitation status Living alone 24 (14.3) Living with family 144 (85.7) Education level Associate’s degree or lower 25 (14.9) Bachelor’s degree or higher 143 (85.1) Nursing work environments 2.47 ± 0.40 Nurse participation in hospital affairs 2.33 ± 0.47 Nursing foundations for quality of care 2.68 ± 0.41 Nurse managers’ ability, leadership, and support of nurses 2.69 ± 0.54 Staffing and resource adequacy 2.24 ± 0.62 Collegial nurse-physician relations 2.27 ± 0.61 Experience of quarantine No 123 (73.2) Yes 45 (26.8) Training/orientation of infection control No 82 (48.8) Yes 86 (51.2) Level of nurse staffing Appropriate 70 (41.7) Inappropriate 98 (58.3) Availability of PPE Appropriate 78 (46.4) Inappropriate 90 (53.6) Convenience of EHR Convenience 110 (65.5) Inconvenience 58 (34.5) Experience of witnessing COVID-19 patient death No 124 (73.8) Yes 44 (26.2) Length of working period in the COVID-19 isolation ward 26.61 ± 18.31 PTSD 15.77 ± 16.57 ≤ 33 137 (81.5) > 33 31 (18.5) Note: COVID-19 Coronavirus disease 2019, EHR Electronic health records, PPE Personal protective equipment, PTSD Post-traumatic stress disorder, SD Standard deviation 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.' (Table presented.)

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.' The original article [1] has been corrected.
