 AB    OBJECTIVES: To determine the probability of vascular access devices
       (VAD) survival without removal due to infection and any significant
       difference between HIV+ve and HIV-ve patients and between Hickman
       catheters and ports. METHODOLOGY: A review of the medical records of
       patients in whom vascular access devices (VAD) had been either inserted
       or removed between January 1 1991 and December 31 1993. The surveillance
       was continued until April 8 1994. Kaplan-Meier survival curves were
       plotted after censorship of VAD survival times for patients who died
       with the VAD insitu, or were alive at April 8 1994 without any VAD
       incident. VAD survival was compared by the logrank test. RESULTS: HIV+ve
       patients: 44 with VAD(all ports) (7570 patientdays) recorded 10
       infections, 2 blockages and 10 removals (8 due to infection). HIV-ve
       patients: 35 with Hickmans recorded 17 infections, 2 blockages and 19
       removals(15 due to infection). 13 with ports recorded 3 infections, 1
       blockage and 3 removals(none due to infection). Logrank test of
       Kaplan-Meier probability of port survival was: HIV+ve v HIV-ve chi 2 =
       3.27, p > 0.05; HIV+ve v Hickman chi 2 = 9.69, p < 0.01; HIV+ve v HIV-ve
       ports chi 2 = 0.40, p > 0.50; all ports v Hickman chi 2 = 15.92, p <
       0.001 CONCLUSIONS: Ports, in general, have a higher probability of
       survival than Hickmans. There is no significant difference in the
       probability of VAD survival between HIV+ve and HIV-ve patients.
