Introduction Chlorhexidine cord care is an effective intervention to reduce neonatal infection and death in resource constrained settings. The Federal Ministry of Health of Ethiopia adopted chlorhexidine cord care in 2015, with national scale-up in 2017. However, there is lack of evidence on the provision of this important intervention in Ethiopia. In this paper, we report on the coverage and determinants of chlorhexidine cord care for newborns in Ethiopia. Methods A standardized Nutrition International Monitoring System (NIMS) survey was conducted from January 01 to Feb 13, 2020 in four regions of Ethiopia (Tigray, Amhara, Oromia, and Southern Nations, Nationalities and Peoples Region [SNNPR]) on sample of 1020 women 0–11 months postpartum selected through a multistage cluster sampling approach. Data were collected using interviewer-administered questionnaires in the local languages through home-to-home visit. Accounting for the sampling design of the study, we analyzed the data using complex data analysis approach. Complex sample multivariable logistic regression was used to identify the determinants of chlorhexidine cord care practice. Results Overall, chlorhexidine was reportedly applied to the umbilical cord at some point postpartum among 46.1% (95% confidence interval [CI]: 41.1%– 51.2%) of all newborns. Chlorhexidine cord care started within 24 hours after birth for 34.4% (95% CI: 29.5%– 39.6%) of newborns, though this varied widely across regions: from Oromia (24.4%) to Tigray (60.0%). Among the newborns who received chlorhexidine cord care, 48.3% received it for the recommended seven days or more. Further, neonates whose birth was assisted by skilled birth attendants had more than ten times higher odds of receiving chlorhexidine cord care, relative to those born without a skilled attendant (adjusted odds ratio [AOR]: 10.36, 95% CI: 3.73–28.75). Besides, neonates born to mothers with knowledge of the benefit of chlorhexidine cord care had significantly higher odds of receiving chlorhexidine cord care relative to newborns born to mothers who did not have knowledge of the benefit of chlorhexidine cord care (AOR: 39.03, 95% CI: 21.45–71.04). Conclusion A low proportion of newborns receive chlorhexidine cord care in Ethiopia. The practice of chlorhexidine cord care varies widely across regions and is limited mostly to births attended by skilled birth attendants. Efforts must continue to ensure women can reach skilled care at delivery, and to ensure adequate care for newborns who do not yet access skilled delivery.
The study was conducted in four regional states of Ethiopia, viz. Tigray, Amhara, Oromia, and Southern Nations, Nationalities and Peoples Region (SNNPR) (Fig 1). As per the 2007 National Housing Census of Ethiopia, these four regions cover more than 85% of the national population [24]. The study included 12 zones (second-level of the administrative division in Ethiopia) in the four regions–three from each region: Central Tigray, East Tigray and South Tigray zones of the Tigray region; West Gojam, East Gojam and Awi zones of Amhara region; Horo-Guduru, West Wollega and East Wollega zones of Oromia region; and Hadiya, Kembata-Tembaro and Sidama zones of the SNNPR region. A total of 71 districts (third-level administrative division) and 104 villages were covered in the 12 zones in which the study was conducted. SNNPR: Southern Nations, Nationalities, and Peoples Region. Note: Currently there are two additional regions, namely Sidama and South West Ethiopia regions, which were created after the survey was conducted. The map is constructed based on shapefile obtained from open AFRICA (https://africaopendata.org/dataset/ethiopia-shapefiles; accessed on 01 February 2022). This was a community-based cross-sectional survey conducted from January 01 to Feb 13, 2020 among women 0–11 months postpartum with live birth and permanently residing in the selected villages. The survey was conducted as part of the baseline assessment for the Nutrition International’s (NI’s) Maternal, Newborn Health and Nutrition (MNHN) Programme planned to be implemented in the survey districts over 2020–2024. Promoting the use of Chlorhexidine for cord care is among the package of services included in the NI’s MNHN programme. As this study was part of a larger survey, sample size was estimated to ensure that it would be sufficient to estimate all key indicators covered by the NI-supported MNHN programme. Accordingly, a sample size of 1020 was found to be adequate for estimating all key variables. As for chlorhexidine in particular, assuming the expected proportion of chlorhexidine cord care among newborns to be 50% (to maximize the sample size) and considering a design effect of 2.0 to account for precision loss due to multistage cluster sampling, the sample size of 1020 used for the present study was sufficient to estimate the 95% confidence interval (CI) of the proportion of newborns who received chlorhexidine cord care within a margin of error of +/-4.34%. This sample size was also sufficient to analyze the determinants of chlorhexidine cord care. At the 95% confidence level and 80% power, taking the proportion of newborns who received chlorhexidine cord care in the reference categories of the determinants reported in this paper (region of residence, mother’s education, skilled attendance at birth, and mother’s knowledge of the benefit of chlorhexidine cord care) as the proportion of the outcome in the ‘unexposed group’, the sample size was adequate to detect statistically significant effects for adjusted odds ratios in the range of 1.7 to 3.0. The multistage cluster sampling approach involved the following. In the first stage, 71 districts were identified using probability proportional to size (PPS) technique from across all 12 zones. For the second stage sampling, in most of the districts, one kebele (a lower administrative unit in Ethiopia) was selected at random. Because of relatively smaller population sizes in some of the districts, in a few districts (especially in Tigray region) PPS technique resulted in selection of 2–4 kebeles 2–4 kebeles. Ultimately, one village was selected from each kebele using simple random sampling (SRS) technique. In each selected village, a home-to-home search was done to identify eligible women. The first 10 eligible women 0–11 months postpartum with live birth identified during the home-to-home search were included in the study. If a sufficient number of eligible women was not found in a village, the remaining number of women was obtained from an adjacent village in the same kebele. The dependent variable for this study was chlorhexidine cord care of neonates. It was measured as the proportion of newborns who received chlorhexidine to the umbilical stump within 24 hours of birth in the previous one year. The information on chlorhexidine use for cord care was obtained through the mothers’ self reports. A coloured picture of chlorhexidine tube was shown to the mothers to help them recall what chlorhexidine is. Various plausible maternal sociodemographic, knowledge and health care-related variables were analyzed as the determinants of chlorhexidine core care. Sociodemographic variables included maternal education and region of residence. Maternal education was categorized as no formal education, primary education, secondary education and higher education, whereas region of residence comprised of the four regions in which the survey was conducted, namely Tigray, Amhara, Oromia and SNNPR. Maternal knowledge of the benefit of chlorhexidine cord care was another independent variable. Mothers who were able to name at least one of the three benefits of chlorhexidine cord care–namely ‘it prevents infection’, ‘it keeps the area clean’, and/or ‘it prevents death’–were categorized as having at least some knowledge (yes), and mothers who could not name any of those benefits were categorized as having no knowledge (no). Mothers’ knowledge of how long to apply chlorhexidine to the umbilical stump was also included as an independent variable. Mothers who stated that chlorhexidine should be applied for seven or more days were considered as having knowledge (yes), while mothers who described the proper duration of chlorhexidine application to be less than seven days and those who couldn’t describe chlorhexidine application as a way of caring for the cord were considered as having no knowledge of the correct duration of chlorhexidine cord care (no). The health-care related variable was skilled birth attendance during the last birth (i.e., in the previous one year). Births attended by doctors/clinical officers and nurses/trained midwives were categorized as having been attended by skilled birth attendants (yes); otherwise, births were categorized as having not been attended by skilled birth attendants (no).
