This study investigated the effectiveness of simple-to-implement adjustments of phototherapy devices on irradiance levels in a cross-section of Nigerian hospitals. A total of 76 phototherapy devices were evaluated in 16 hospitals while adjustments were implemented for a subset of 25 devices for which consent was obtained. The mean irradiance level was 7.6±5.9 μW/cm2/nm for all devices prior to adjustments. The average irradiance level improved from 9.0 μW/cm2/nm to 27.3 μW/cm2/nm for the adjusted group (n=25) compared with 6.8±5.4 μW/cm2/nm for the unadjusted group (n=51). Simple, inexpensive adjustments to phototherapy devices with sub-optimal irradiance levels can significantly improve their effectiveness to acceptable international standards and should be widely promoted in resource-constrained settings.
