To determine trends in a number of hemodialysis associated diseases and practices, the Centers for Disease Control and Prevention, in collaboration with the Health Care Financing Administration, completed a mail survey of chronic hemodialysis centers in the United States in 1992.
Of 2,321 centers surveyed, 2,170 (93%) representing 170,028 patients and 43,535 staff members responded.
In 1992,2,049 (94%) centers used bicarbonate dialysate as the primary method of dialysis, 765 (35)% used high flux dialysis, and 1,569 (72%) reused dialyzers, continuing the trends toward increased use of these methods.
Central (subclavian or jugular) venous catheters were used in = 1 patient as permanent vascular access for hemodialysis at 69% of dialysis centers.
Hepatitis B surface antigen was present at low frequency in patients (incidence=0.1%, prevalence=1.2%) and staff members (incidence=0.03%, prevalence=0.3%). Among centers that had = 1 hepatitis B surface antigen positive patient, the incidence of hepatitis B virus infection was lower in those centers that used a separate room for dialysis of patients positive for hepatitis B surface antigen.
From 1991 to 1992, reported hepatitis B vaccine coverage increased from 17% to 24% among patients and from 56% to 69% among staff members ; in absolute terms, these were the largest single year increases since introduction of hepatitis B vaccine.
The prevalence of antibody to hepatitis C virus was 8.1% among patients and 1.6% among staff members.
