Sibling visits and viral infection in the neonatal intensive care unit.

BACKGROUND

Sibling visits to the neonatal intensive care unit (NICU) are a part of family-centered care, which is now being increasingly endorsed as a positive development in patient care. Sibling visits, however, pose a risk of viral infection, and hence many NICU in Japan impose strict limits on the practice. The aim of this study was therefore to assess whether sibling visits to the NICU are related to an increase in the nosocomial viral infection rate.

METHODS

This retrospective study was conducted between April 2012 and March 2017 at Tokyo Metropolitan Children's Medical Center in Japan. Sibling visits were implemented after screening for symptoms of viral illness. Symptomatic patients in the NICU were tested for common viruses on rapid antigen test and polymerase chain reaction. The number of sibling visits and the rate of nosocomial viral infections were examined on Spearman's correlation test.

RESULTS

The total number of sibling visits and rate of nosocomial viral infection in the NICU was 102 and 0.068 per 1,000 patient-days during the study period, respectively. The number of enterovirus, respiratory syncytial virus, human metapneumovirus, influenza virus A, and Herpes simplex virus infections was 3, 2, 1, 1, 1, and 1, respectively. No infections were identified after sibling visits. The number of sibling visits and the rate of nosocomial viral infections were not correlated (correlation coefficient, -0.1; P = 0.873).

CONCLUSION

Sibling visits to the NICU did not result in an increase in the nosocomial viral infection rate.
