Background

Hemodialysis (HD) patients are expected to minimize interdialytic fluid gains and manage their blood pressure (BP) with antihypertensive (AHT) medications. Due to a paucity of data reporting patients’ knowledge and understanding of fluid and BP management, we conducted a prospective cross-sectional survey with retrospective medical record review at three HD clinics in Illinois.

Methods

HD patients were consented and interviewed using a standardized cross-sectional survey consisting of 50 questions on fluid and BP management. Patients were paid $10 for their participation. Six months of retrospective data was collected from medical records.

Results

Ninety-two patients completed the survey, and 38/92 were not aware of the last time their dry weight (DW) was changed. Patients reported their last DW change was made 5.93 +/- 15.3 months ago on average. Of the 54 patients who reported knowing the last time their DW was changed, 31/54 reported it was raised, 17 lowered, and 6 were not sure what changes were made. Medical records indicated that patients were not aware of the majority of DW changes. Over 3 months, DWs were changed an average of 2.54 +/- 2.18 times. Twenty four patients (26%) could not list their current or any previous DWs, while those who listed a DW were on average 3.73 +/- 10.16 kg away from the DW listed within their medical record.
Forty-six patients were currently on 1 or more AHT medications. Of these, the average time since AHT medications were last changed was 15.22 +/- 16.4 months. The majority of patients (78/ 92) patients were interested in (or already) measuring their BP at home. Figure 1 shows how patients rated the likeliness of a direct relationship of their interdialytic fluid gains and BP.

Conclusion

Despite a desire to learn, most HD patients lack an understanding of the basic principles of fluid & BP management. There is a need for a structured education program for those initiating dialysis that encompasses fluid and BP management.
