Recently, research has focused on the potential long-term effects of repetitive painful episodes that occur during hospitalization in the Neonatal Intensive Care Unit (NICU).

Researchers have theorized that exposure to repetitive pain early in the neonatal period may affect neurodevelopmental outcomes. The purpose of this study was to determine if there was an association between the frequency of painful procedures experienced during NICU hospitalization and neurodevelopmental scores, defined as Bayley Mental Developmental Index (MDI) scores, at two years of age.

MDI scores were obtained as part of a secondary data analysis. Inclusion criteria for the current study were limited to children who had MDI scores documented at two years of age. Medical records were retrospectively reviewed for demographic data, the number and type of painful procedures, the amount of pain and sedation medication and specific medical conditions experienced during participants NICU hospitalization.

Severity of illness scores were also calculated. Once collected, data was entered into SPSS for statistical analysis. After eliminating outliers and those with incomplete medical records, the study sample consisted of 103 participants.

Significant positive correlations were found between MDI scores and gestational age at birth (r = .196, p < .05), birth weight (r = .226, p < .05) and maternal education (r =.290, p < .01). Significant negative correlations were noted between MDI scores and severity of illness (r = -.278, p <.0l) and the total number of untreated painful procedures (r = -.199, p < .05) during NICU hospitalization.

Sequential regression analysis determined that the total number of untreated painful procedures (R 2 = .150, F[1, 98] = .003, p = .95) did not reliably improve the prediction of MDI scores above the prediction of MDI scores by maternal education, birth weight and severity of illness. Controlling for maternal education and severity of illness scores, partial correlation between MDI scores and the number of untreated painful procedures was found to be non-significant (r12.34 = -.031, p = .758).
