The specific effect of session time versus frequency of therapy on outcomes is more difficult to determine since time and frequency are interrelated.\u00a0 Nonetheless, various clinical experiences have shed light on the respective roles of these variables.\u00a0 The Tassin experience is often quoted as an example of how long dialysis session time may favorably affect outcomes1<\/sup>.\u00a0 The annual fractional mortality rate is calculated to be a mere 4% over a period of four years for patients receiving an average dialysis time of 8 hours\/session.<\/p>\n

\"\"<\/strong>Comparative mortality rates among various series and registers.\u00a0 The normalized mortality rates bear little relationship to treatment time.\u00a0 Based on references 2 and 3.<\/h6>\n

In reviewing the survival rate of various large series and registry data, one of the closest survivals are those reported with only 2.3 hours thrice weekly by Gotch2,3<\/sup>.\u00a0 Albeit this close ranking to the Tassin experience, there is a significant difference in survival.\u00a0 The actual survival is closer to the series with lower session length.\u00a0 Thus, session time per se should not be considered the most significant determinant of outcome, but the marked difference between the Tassin and Gotch mortality rates still suggest that session time may be important.<\/p>\n
