Data-based Recommendations for Dialysis

Q) I work in a cardiology practice. Recently, a patient on dialysis mentioned that her nephrology practitioner recommended either home therapy or nocturnal dialysis. Why would someone recommend these, and what are the differences between home, nocturnal, and regular daytime dialysis?

Patients usually require dialysis when 90% or more of their renal function is lost.⁵ This can happen acutely or result from a chronic process. Dialysis performs many of the functions of a kidney, such as removing waste and fluid buildup that damaged kidneys cannot. It also helps maintain electrolyte balance.

There are several forms of hemodialysis including home, incenter, and nocturnal; the most frequently used is in-center hemodialysis.⁵ Patients on in-center hemodialysis visit the center three times a week, and their treatments last from three to five hours; the nationwide average is four hours. These patients have very restricted schedules and must maintain their appointments with limited flexibility. Food, drinks, and nonmedical personnel may not be allowed in the treatment area. Between treatments, patients must follow a diet that restricts fluid, sodium, and potassium intake.

Home dialysis has become a popular alternative, since it may be done in a location and at a time that is convenient for the patient. With more flexibility, many patients are able to continue working and feel like they have a more “normal” life. Types of home dialysis include home hemodialysis (HHD) or peritoneal dialysis (PD). A relative or friend may need to assist the patient during HHD, which is undergone more frequently (between five and seven days per week) and for a shorter duration of time than in-center dialysis. PD is done every day, either at night or multiple times throughout the day. Although no partner is needed for PD, a medical provider is available by phone to address any concerns that may arise during treatment.

Nocturnal hemodialysis is similar to daytime in-center hemodialysis, but it occurs while the patient is asleep. The treatment duration is longer (an average of eight hours per treatment). The slower blood flow allows for gentler dialysis. Patients who undergo nocturnal hemodialysis have higher survival and lower hospitalization rates, with better phosphorus control and blood pressure.⁶ This is attributed to the slower removal of excess fluid and more effective clearance of toxins.

So, why is your patient being encouraged to consider home or nocturnal dialysis? Studies have shown that for the cardiac patient, slower, gentler dialysis is preferable.⁷ The clinician who recommended it has the patient’s best interest in mind. —TAH
