In a regional CAPD program in Northern Alberta, Canada, the peritonitis rates among patients undergoing CAPD treatment were quite high: 1/8.3 and 1/7.4 per patient month from a population of 75 and 76 patients in 1989 and 1990 respectively. Our patient population is comprised of different ethnic groups, separated widely from the dialysis centre; over half of them are above the age of 60 years. As it is not possible to change the patient characteristics in our centre, we switched to the Twin-bag disconnect system in 83 out of a total of 103 patients in 1991. With this change our overall peritonitis rate has significantly improved to 1/14 per patient months and 1/17 per patient months in patients using the Twin-bag system. This improvement in the peritonitis rate has occurred without any change in our patient characteristics. We find the improvement in our peritonitis rate is due to the use of the new Twin-bag system, which provides total disconnection with no spikes and thereby reduces peritonitis due to touch contamination.
在加拿大艾伯塔省北部的一个区域性持续性非卧床腹膜透析（CAPD）项目中，接受CAPD治疗的患者腹膜炎发生率相当高：1989年75名患者和1990年76名患者的腹膜炎发生率分别为每患者月1/8.3和1/7.4。我们的患者群体由不同种族组成，居住地点离透析中心很远；其中一半以上患者年龄超过60岁。由于在我们中心无法改变患者特征，1991年我们在总共103名患者中的83名患者中改用了双联袋断开系统。随着这一改变，我们的总体腹膜炎发生率显著改善，使用双联袋系统的患者腹膜炎发生率降至每患者月1/14和1/17。腹膜炎发生率的这种改善在我们的患者特征未发生任何变化的情况下出现。我们发现腹膜炎发生率的改善归因于使用了新的双联袋系统，该系统实现了完全断开连接且无穿刺装置，从而减少了因接触污染导致的腹膜炎。
