Profile of congenital heart disease and access to definitive care among children seen at Gulu Regional Referral Hospital in Northern Uganda: a four-year experience

Abstract

Abstract Objectives The aim of this study was to describe the profile of Congenital Heart Disease [CHD] and access to definitive surgical or catheter-based care among children attending a regional referral hospital in Northern Uganda. Methods This was a retrospective chart review of all children aged less than 17 years attending Gulu Regional Referral Hospital Cardiac clinic from November 2013 to July 2017. Results A total of 295 children were diagnosed with CHD during the study period. The median age at initial diagnosis was 12 months [IQR: 4–48]. Females comprised 59.3% [n =  175] of cases. Diagnosis in the neonatal period accounted for only 7.5 % [n = 22] of cases. The commonest CHD seen was ventricular septal defect [VSD] in 19.7 % [n = 58] of cases, followed by atrioventricular septal defect (AVSD) in 17.3 % [n = 51] and patent ductus arteriosus (PDA) in 15.9 % [n = 47]. The commonest cyanotic CHD seen was tetralogy of Fallot [TOF] in 5.1 % [n = 15], followed by double outlet right ventricle [DORV] in 4.1 % [n = 12] and truncus arteriosus in  3.4% [n = 10]. Dextro-transposition of the great arteries [D-TGA] was seen in 1.3 % [n = 4]. At initial evaluation, 76 % [n = 224] of all CHD cases needed definitive intervention and 14 % of these children [n = 32] had accessed surgical or catheter-based therapy within 2 years of diagnosis. Three quarters of the cases who had intervention [n = 24] had definitive care at the Uganda Heart Institute (UHI), including all 12 cases who underwent catheter-based interventions. No mortalities were reported in the immediate post-operative period and in the first annual follow up in all cases who had intervention. Conclusions There is delayed diagnosis of most rural Ugandan Children with CHD and access to definitive care is severely limited. The commonest CHD seen was VSD followed by AVSD. The majority of patients who had definitive surgery or transcatheter intervention received care in Uganda.
