RESUMEN
AIM: The effect of different neonatal unit access hour policies on parental visiting duration is unknown. Therefore, we analysed the effects of access hours policies and parental education on parental visiting duration. METHOD: This prospective longitudinal cohort study was carried out in a level III neonatal unit from October 2020 to May 2022. Three cohorts were compared. The baseline cohort included 51 preterm infants with restricted visiting hours (October 2020 to May 2021). Cohort 1 comprised 35 preterm infants after liberalisation of visiting hours (June 2021 to November 2021). Cohort 2 consisted of 26 preterm infants after an educational program was implemented (December 2021 to May 2022). The primary outcome was the mean daily parental visiting duration. RESULTS: Mean maternal visiting duration was 172 (standard deviation, SD ± 49.2), 195 (SD ± 64.4.), and 258 (SD ± 71.1) minutes/day at baseline and in cohorts 1 and 2 (significant increase from baseline and cohort 1 to cohort 2, p < 0.001). Mean paternal visiting duration did not change significantly across the cohorts: 133 (SD ± 47.2), 135 (SD ± 83.5), and 165 (SD ± 71.3) minutes/day. CONCLUSION: Liberalisation of access hours did not increase parental visiting duration. Parental and staff education significantly increased maternal but not paternal visiting duration.
