Bernardini
Predicting compliance in home peritoneal dialysis patients
42nd Annual Conference of the ASAIO
ASAIO J (May) 42:(2):102 1996

One very important problem with any home dialysis regimen is compliance with the treatment. There has been much discussion of this pertaining to predicted/measured creatinine ratios. In this study, Bernardini use supply inventory at two visits 4-8 weeks apart as a gold standard of compliance with a PD regimen in 10 patients. Based on the inventory, 50% of patients were non-compliant! The M/P creatinine ratio, in agreement with recent published results by Burkart et al and Blake et al failed to predict non-compliance. One thing which did predict non- compliance with very high accuracy was the DABS, a multidimensional psychological test (questionnaire) which used 40 adjectives to measure positive and negative affects. This test had an 80% sensitivity and 100% specificity.

Comment: Of course, given an n of 10 patients, one needs to be bit careful, but as this DABS questionnaire takes only 5 minutes to complete, it certainly deserves further evaluation in this very important area. (John T. Daugirdas, M.D., University of Illinois at Chicago)

Additonal comments by Peter B. DeOreo MD, Case Western Reserve University, Cleveland OH
This is a limited study done in patients with a high prevalance of non compliance. Compliance was verified by supply inventory evaluated on home visit. A low (negative) affect score on a self rank correlated with poor compliance. A low affect score was better than biochemical, dialysate creatinine, and staff evaluations.

A low score probably points to depression. Others (Kimmel, More, Hays) have shown depression to be a risk factor for non compliance in both ESRD and in general medical settings. It is no surprise that neither patient self report of compliance nor staff predictions were either sensitive or specific. Health care workers and patients are likely to have differing opinions on a patient's health status, with the health care worker underestimating the extent of physical and psychosocial disability. This study may be pointing to the under diagnosis of depression. It will be interesting if, in their larger series, the authors develop intervention strategies.
