OBJECTIVE: Identification of frequency and severity of @entity4789 / @entity6331 ( @entity6470 / @entity6668 ) in the catchment area of Gauteng hospitals. DESIGN: A retrospective descriptive analysis using hospital-based computer databases. SETTING: Helen Joseph, Chris Hani Baragwanath and Johannesburg General hospitals, Gauteng, South Africa. SUBJECTS: Three hundred and twelve of 493 (63%) paediatric @entity6470 / @entity6668 @entity1 with documented addresses seen from 1993 to 1995. METHODS: A proportional analysis, with the total @entity299 ( @entity299 ) @entity1 seen in an area as the denominator, was employed to identify areas with prevalent and/or severe @entity6470 / @entity6668 . @entity66 was defined as that requiring surgery or balloon valvuloplasty. RESULTS: 32.7% of @entity6470 / @entity6668 @entity1 came from outside Gauteng, and 70.2% of those seen at Chris Hani Baragwanath Hospital were not from Soweto. KwaZulu-Natal, Northern Province, Mpumalanga and Evaton had a significantly higher-than-expected ratio of @entity6668 / @entity299 @entity1 and were identified as priority areas at high risk for @entity6668 . Gauteng and some Johannesburg suburbs had a significantly lower-than-expected ratio and therefore had a relatively low risk for @entity6668 . 32.9% of @entity6668 @entity1 had severe disease. The severity rate for Gauteng residents was 34.8% and for non-Gauteng residents 51%. Significantly more severe cases than expected came from KwaZulu-Natal, Northern Province, Mpumalanga and Gauteng south. Significantly fewer severe RHID @entity1 than expected came from Gauteng, especially Gauteng centre. CONCLUSIONS: A high frequency of @entity6470 / @entity6668 and severe disease was recorded in @entity1 living in KwaZulu-Natal, Northern Province and Mpumalanga.

Frequency and severity of XXXX in the catchment area of Gauteng hospitals, 1993-1995.
