Geospatial distribution of severe paediatric intussusception in KwaZulu-Natal province, South Africa

Abstract

Introduction intussusception in South African (SA) children is often severe. A proportion of cases require management at quaternary hospitals which are a scare resource in SA. A geospatial investigation of severe paediatric intussusception (SPI) in the KwaZulu-Natal (KZN) province of SA would assist with identifying regions which should be targeted for preventative interventions. This could reduce resource utilisation for this condition at quaternary hospitals. The objective of this study was to determine the geospatial distribution of SPI in KZN. Methods this was a retrospective analysis of data for patients with SPI who were admitted to a quaternary hospital in KZN over an 11-year period. Data related to patient demographics, duration of hospitalization, surgical intervention, inpatient mortality and residential postal code were extracted from the electronic hospital admissions system. Each residential postal code was linked to a corresponding KZN district municipality. Descriptive statistical methods were used to determine the distribution of various characteristics in the study sample. Semi-quantitative geospatial analysis was used to determine the distribution of patients with SPI in each KZN district municipality. Results the study sample consisted of 182 patients with SPI. Most patients were <1 year old (83.5%), male (51.1%) and black African (87.9%). All patients underwent surgical intervention. Inpatient mortality was 2.7%. The majority of patients in the study sample resided in the eThekwini and King Cetshwayo district municipalities (51.1% and 14.8%, respectively). Conclusion preventative interventions for SPI should be considered for rollout in the eThekwini and King Cetshwayo district municipalities of KZN, SA.

Geospatial methodology for determining the regional prevalence of hospital-reported childhood intussusception in patients from India

“…The spatial aspects of the intussusception cases, including their geographical distribution, distance, density and direction, are presented in this manuscript. Previous studies have reported that the epidemiology of intussusception varies according to the country and region 2 , 26 . However, granular examination of the location of patients reported at sentinel surveillance network hospitals, with the help of geostatistics techniques, revealed that the regional pattern inferred from hospital-based studies may be misleading.…”

The impact of same-day antiretroviral therapy initiation on retention in care and clinical outcomes at four eThekwini clinics, KwaZulu-Natal, South Africa

“…The eThekwini district is densely populated (3,702,231) comprising of urban, semi-urban, and rural areas [ 24 ]. We selected study clinics from the three settings; (i) 2 facilities (Ithembalabantu and D clinic) in a densely populated Umlazi township also known to have high HIV prevalence of 35%, [ 25 ] (ii) Pinetown clinic in Pinetown, a semi suburb town (these are places that offer a balance between township and suburb tranquillity) surrounded by townships and informal settlements who all seek services at the facility and (iii) Qadi clinic in rural Umzinyathi district municipality north of eThekwini municipality. UMzinyathi district has high levels of poverty, unemployment, and HIV/AIDS [ 25 ].…”

Mother, daughter, sister, wife? interogating construction of South African Indian women's Identity – a study of South African Indian women playwrights and our plays.

“…This was one of my intentions with writing and directing Devi (2019), with the hope that such an accessible text and production could reach and evoke in audiences a deep-rooted response to my work, especially my fellow ISAW, SAIW and/or SAWOID. As outlined above, my thesis consists of nine chapters, each with a particular focus.…”

“…My identity as an SAIW has driven every aspect of my work, and is the heart of my study. Uncovering how this influenced the play, Devi (2019), I wrote and staged, as well as the research I conducted, is thus hugely significant to my thesis.…”

“…As I sat quietly, for what felt like the first time in weeks amid the frenzy of rehearsals, to write my playwright and director's note for my production Devi (2019), I found myself reflecting on the meaning of my play, my thesis, my life really. I realised 1 that the most profound connection to all this could be found in one woman: my mother.…”
