Behavioral Intervention and Adherence in Dialysis

Summary

The aim of the proposed work is to conduct a randomized controlled trial (RCT) evaluation of a behavior change intervention designed to enhance fluid-intake adherence (compliance) among hemodialysis patients. Patient non-adherence (non-compliance) with fluid-intake restrictions is a highly pervasive problem in the hemodialysis population with substantial consequences in terms of increased patient morbidity and mortality. Given the prevalence and clinical importance of adherence among ESRD patients, the design and evaluation of interventions to improve patient adherence is critically important. Surprisingly, however, little such empirical work has been conducted in this area.

The proposed RCT involves testing the efficacy of a behaviorally based, group-administered, "behavioral self regulation" intervention designed to increase adherence to fluid intake restrictions among hemodialysis patients. This structured intervention is designed to be delivered by healthcare providers in a clinical setting to groups of 4-10 patients over seven, one-hour weekly sessions. This study will compare the effect of the structured intervention group with the effect of an educational and support group on fluid-intake adherence in a sample of approximately 200 fluid non-adherent center hemodialysis patients over a 26-week follow-up period. Both clinical (interdialysis session weight gain) and self-report indices of fluid-intake adherence will be examined. We believe that the proposed research is of potentially very high impact given the high prevalence and clear clinical consequences of hemodialysis patient nonadherence and the potential for a relatively low-cost, structured intervention to significantly reduce this type of maladaptive patient behavior in the hemodialysis treatment context.

Medical and Biotech [MESH] Definitions

Hospital units in which care is provided the hemodialysis patient. This includes hemodialysis centers in hospitals.

Long-term maintenance hemodialysis in the home.

The combination of hemodialysis and hemofiltration either simultaneously or sequentially. Convective transport (hemofiltration) may be better for removal of larger molecular weight substances and diffusive transport (hemodialysis) for smaller molecular weight solutes.

Solutions prepared for hemodialysis. The composition of the pre-dialysis solution may be varied in order to determine the effect of solvated metabolites on anoxia, malnutrition, acid-base balance, etc. Of principal interest are the effect of the choice of buffers (e.g., acetate or carbonate), the addition of cations (Na+, K+, Ca2+), and addition of carbohydrates (glucose).

Telephone surveys are conducted to monitor prevalence of the major behavioral risks among adults associated with premature MORBIDITY and MORTALITY. The data collected is in regard to actual behaviors, rather than on attitudes or knowledge. The Centers for Disease Control and Prevention (CDC) established the Behavioral Risk Factor Surveillance System (BRFSS) in 1984.
