To explore the importance of hospital infection knowledge training for medical laboratory interns during clinical practice by investigating their grasp of hospital infection knowledge.

A total of 129 interns majoring in medical laboratory in the Second People's Hospital of Lianyungang from 2017 to 2022 were selected as subjects. Paired t-tests were used to compare the theoretical and practical knowledge of the interns before and after hospital infection training, and to analyze changes in the occurrence of hospital infection adverse events among the interns.

The theoretical scores of interns before and after training were (13.96±1.96, 25.50±2.50), (13.26 ±1.97, 25.32±2.56), (13.67±2.06, 26.00±2.47), (13.10±2.17, 25.60±2.44), (12.81±1.94, 24.56±2.50) and (13.54±2.00, 25.50±2.57) from 2017 to 2022, respectively. The theoretical knowledge scores of interns were significantly improved after the hospital infection knowledge training, and the difference between the two groups was statistically significant (P<0.05). The technical knowledge scores of interns before training and after training were (11.88±3.10, 23.88±2.25), (8.84±2.59, 25.16±2.77), (10.89±2.87, 23.39±1.79), (10.20±2.07, 23.75±2.63), (9.69±2.26, 23.56±1.66) and (14.21±2.30, 24.29±2.42) from 2017 to 2022, respectively. The technical knowledge scores of interns were also significantly improved after the hospital infection knowledge training, and the difference between the two groups was statistically significant (P<0.05). The incidence of hospital-acquired infection caused by interns during clinical practice from 2017 to 2022 was 12.50%, 10.53%, 5.56%, 5.00%, 3.13% and 0.00%, respectively. In addition, the annual incidence showed a decreasing trend as a whole.

The training of hospital infection knowledge can significantly improve the awareness and ability of hospital infection protection of interns majoring in medical laboratory, and it plays an extremely important role in the prevention and control of hospital infection.
