Abstract
Background: Congenital heart disease (CHD) is the most common malformation in newborns.In Africa alone, 500,000 live newborns are born each year with CHD. Sub-Saharan Africacontributes a larger portion of these numbers. Nearly one fourth of these CHDs are critical CHDsand thus need to be diagnosed and managed timely. Time to first diagnosis of these defectsvaries across countries. Delayed diagnosis is common in third world countries. The prevalence of delayed diagnosis in Ethiopia is unknown. Knowing the magnitude of late diagnosis would helpin designing the mechanisms for early detection and possible intervention. With appropriate andtimely interventions, more than 85% of all children with CHD can survive to adulthood.
Objective: The aim of this study was to determine the magnitude of delayed diagnosis ofcongenital heart diseases and associated factors in TASH, 2023.
Methods and materials: The study was conducted in TASH at department of Pediatrics andChild Health. A cross-sectional design was employed. The data was collected using kobotoolbox tool and was exported to SPSS version 29 for analysis. Descriptive statistics was used to examine participants’ socio-demographic, socioeconomic and clinical characteristics. Binary and multivariate logistic regression analysis was utilized to assess association between variables.
Results: Over half (53.1%) of the study participants had delayed diagnosed of CHD. Themajority of patients (84.4%) with cyanotic HDs were diagnosed late. The proportion of delayeddiagnosis among acyanotic CHDs was 45.4%. The median age at diagnosis for acyanotc CHDwas 6 months IQR [1.5-24] whereas the median age at diagnosis for cyanotic was 9 months IQR [1.5-29].The probability of delayed diagnosis of CHD was 2.34 times higher in children whose motherdid not have optimal ANC visit during pregnancy (AOR 2.34 95% CI 1.05-5.25 P=0.0.039)
Conclusions: The magnitude of delayed diagnosis of CHD was unacceptably high (53.1%). Thefactors associated with delayed diagnosis were ANC visits, obstetric ultrasound, place of birth,type of birth attendants and type of CHD. To avert delayed diagnosis of CHDs, improvingantenatal care, increasing health care workers awareness and perinatal screening are recommended.
