Clinical Trial of Immediate Skin to Skin Contact at Birth Early vs. Immediate (CPPITLH)
Clinical Trial of Immediate Skin to Skin Contact at Birth Early vs. Immediate (CPPITLH)
SUMMARY: Human lactation is a simple, cost-effective strategy contributing to infant and
 maternal mortality control. Skin to skin contact (SSC), is an immediate postpartum period
 strategy that has proven to benefit the initiation and continuation of human lactation and
 decreased hospitalization during the first week of life. This study aims to determine the
 effect of the initiation of SSC at birth (immediate vs. early) in healthy, full term newborns
 treated at Universidad de La Sabana Clinic, on the duration of exclusive human lactation.

 Research question: What is the effect of immediate SSC at birth (immediate vs. early) on the
 duration of exclusive human lactation in full-term newborns treated at the Universidad de La
 Sabana Clinic?

 Methodology: A random blind clinical trial was performed in which full-term healthy newborns
 that are attended at the Universidad de La Sabana Clinic are included. The blind participants
 will be those persons measuring the results and analysing the data. The sample size is
 calculated for a type I error of 5%, a two tailed type II error of 20%, therefore estimating
 percentage losses of 30%; 150 infants were included per group. Randomization will be
 performed using permuted, size 6 blocks. Descriptive analysis will be conducted using central
 tendency and dispersion measurements. A bivariate analysis will be performed to determine
 which variables are associated with exclusive human lactation at 6 months. For continuous
 variables, the Student t- test will be used for independent samples or the Wilcoxon rank sum
 test, in case the assumptions of normality for the t-tests are not fulfilled. The assumption
 of normality will be evaluated with the Shapiro Wilk and Kolmogorov-Smirnov test. Categorical
 variables in contingency tables will be constructed, assessing independence between variables
 with the Chi-square test or Fisher's exact test when the assumption of the number of cases is
 not met by the cells in the contingency tables, times two. It will be calculated as a
 measurement of the effect of relative risk (RR) with confidence intervals; the adjusted
 measurements will be calculated using a multivaried regression Poisson model, variables with
 significant results will be used in the bivariate analysis and those with biological
 plausibility used for the adjustment. The analysis will be carried out for a two-tailed type
 I error level of 5%. The Stata 11 program will be used for the data analysis. An interim
 analysis will be performed upon submission of half of the expected events (106), setting
 limits for early termination of the trial according to the method proposed by Pampallona and
 Tsiatis (1994).

 Intervention: There will be 2 SSC randomization groups, early vs. immediate. After completing
 the neonatal adaptation process and according to the group assignment, it will proceed to
 leave the newborn with the mother in accommodation. Prior to discharge, the IBFAT scale will
 be applied. Monitoring will initially be performed with a face valuation between 3 and 10
 days of life, then monthly telephone calls for 6 months to verify the status of human
 lactation.

 Results: To determine whether early versus immediate SSC has an impact on the duration of
 exclusive human lactation.
