Replication Data for: Hypothermia amongst neonatal admissions in Kenya: A Retrospective Cohort Study Assessing Prevalence, Trends, Risk Factors, and its Relationship with All-Cause Neonatal Mortality

This is a replication dataset for the publication titled: \"Hypothermia amongst neonatal admissions in Kenya: A Retrospective Cohort Study Assessing Prevalence, Trends, Risk Factors, and its Relationship with All-Cause Neonatal Mortality\". Hypothermia among newborns has reported to increase risk of neonatal mortality. However, these reports have originated from small sampled studies, in small centers and in cross sectional designs. We utilized a large dataset spanning several years collected routinely from 21 different inpatient neonatal units among those born within those hospitals. This data contains `at/during birth` information, examination, diagnoses, treatments, and supportive care and finally discharge information. The objectives were to describe: (i) the burden of hypothermia on admission across 21 newborn units in Kenya, (ii) any trend in prevalence of hypothermia over time, (iii) risk factors for hypothermia at admission, and (iv) hypothermia’s association with inpatient neonatal mortality. The patient level information were analyzed from the `Inpatient Neonatal Dataset.RData`. To explore the role of ambient temperature, we access land surface data as substitutes for the room temperature in the NBU. These land surface temperatures were obtained from MODIS, a satellite source, with a spatial resolution of 1 kilometer (km). Through the Geographical Positioning System (GPS), we acquired the dataset that included daily temperature recordings specifically for the geographical areas of the study hospitals.
