Peritonitis incidence rate is the primary outcome, defined based on International Society for Peritoneal Dialysis (ISPD) 2010 recommendation. Product defect incidence is the secondary outcome, measured by number of incidence of product defect reported by the patients. Given no standard definition, a PD solution product will be considered defective if it is expired on the day of use, incorrect glucose concentration, abnormal clarity or color, physical abnormality of the box and/or the bag, or loosen connector.
