Renal registry in Hong Kong—the first 20 years

Renal Registry was started by the Hospital Authority (HA) in Hong Kong in 1995. It is an online system developed by HA. It collects all patients under care in HA, which is about 90–95 % of all requiring renal replacement therapy (RRT) in Hong Kong. The total number of patients treated increased from 3312 in 1996 to 8510 in 2013. In 2013, there were 3501 renal transplant, 1192 hemodialysis (HD) and 3817 peritoneal dialysis (PD) patients. In 2013, 1147 new patients joined the RRT program, 49.6% of them suffered from diabetic nephropathy. Glomerulonephritis and hypertension are the 2nd and 3rd most common causes of RRT in Hong Kong. The median age was 59.1 years with male to female ratio of 1.54 to 1. Hong Kong practices ‘PD first' policy and the majority of the patients are on CAPD treatment. The ratio of PD to HD was 76.2% to 23.8%. Eighty-six percent of all PD patients are on CAPD; the remaining 14% are on automated peritoneal dialysis (APD). Sixty-five percent of all dialysis patients are on erythropoiesis-stimulating agent treatment. The Hong Kong Renal Registry with online real-time data input and access can provide timely data and information to facilitate patient care and management and also provides invaluable data to help in development and planning of renal services in Hong Kong.
