RESUMEN
UNLABELLED: Longer hemodialysis (HD) as practiced in parts of Europe and Japan may improve both blood pressure control and patient survival. Nevertheless, in the USA, the trend has been to shorten dialysis time using larger dialyzers and increased blood flows. Many patients find the notion of shorter dialysis enticing. Most are unaware ofthe potential benefits of longer dialysis. We surveyed stable chronic HD patients in an urban area, the vast majority of whom received conventional 4-hour treatments, regarding their attitude toward extending their dialysis time to 5 hours. They were informed that longer dialysis has been associated with better blood pressure control and improved survival. One hundred and sixteen patients completed questionnaires during a single dialysis session. Forty-six (40%) agreed to extended dialysis while 70 (60%) did not. There was no difference between the groups with respect to the following variables: age, race, etiology of ESRD, time on dialysis, marital status, number of children at home, number residing in the household, education, or employment status. Male gender was associated with a positive response (p = 0.03). Various suggested and spontaneous reasons were given for a negative response. CONCLUSION: With minimally detailed information, 4 in 10 patients were willing to extend their treatment time to 5 hours in the hope of improving morbidity and survival. No sociodemographic variable except gender was associated with a positive response.
