 AB    OBJECTIVES: To determine 1. the probability of vascular access devices
       (VAD) survival without removal due to infection and of incident free
       port usage at 3, 6 and 12 months; 2. any significant difference between
       the two survival probabilities. METHODOLOGY: A review of the medical
       records of HIV infected 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 port survival times for
       patients who died with the VAD insitu, or were alive at April 8 1994
       without any VAD incident. Infection necessitating removal was compared
       to any infection, blockage or removal by the logrank test. RESULTS: 44
       patients with subcutaneous ports (7670 patientdays) recorded 10
       infections, 2 blockages and 10 removals (8 due to infection).
       Kaplan-Meier probability of port survival (SEM) at 3,6 and 12 months was
       respectively: 0.93 (0.04), 0.83 (0.07) and 0.69 (0.12). Probability of
       incident free usage (SEM) was respectively 0.90 (0.05), 0.71 (0.09),
       0.59 (0.11) chi 2 = 1.024 (p > 0.25) CONCLUSIONS: There is no
       statistical difference between survival affected by adverse incident and
       removal due to infection. Information regarding the probability of
       trouble-free usage may give the patient a more informed choice of venous
       access than quoting removal or infection rates.
