Psychosocial factors and clinical outcome on CAPD.

Patient dropout from chronic peritoneal dialysis (CPD) and transfer to hemodialysis remains a major problem with patients on CPD. Peritonitis, exit-site infections, and medical complications requiring hospitalization often adversely affect the outcome of CPD. The role of psychosocial factors in determining patient outcome and influencing the rates of these complications is not clear. Our group has employed a variety of instruments, including the Patient Related Anxiety Scale (PRAS), Beck's Depression Inventory (BDI), Kupfer-Detre System II somatic symptom scale (KDS-II), and a patient self-assessed quality of life (PAQOL) questionnaire to assess quality of life and to objectively evaluate the psychosocial status of the patient treated with CPD. The present study extends previous observations by relating the results of these psychosocial instruments to the incidence of various complications in 103 patients maintained on CPD. Patients were divided into low-scoring (lowest symptoms of depression, anxiety, somatic symptoms, and best quality of life evaluation), intermediate, and high-scoring (highest symptoms of depression, anxiety, somatic symptoms, and worst quality of life) categories. The peritonitis rates, exit-site infection rates, and days of hospitalization of the three categories were then compared. The results demonstrate significantly higher complication rates in the high-scoring when compared to the low-scoring patients. Thus screening patients maintained on CPD with objective measures of psychosocial functioning may enable caregivers to more accurately predict which patients are at greater risk for developing medical complications.

Quality of life assessment in chronic peritoneal dialysis patients.

Previous studies by our group have attempted to examine quality of life (QoL) issues in a cohort of end-stage renal disease (ESRD) patients maintained on chronic peritoneal dialysis (CPD) by assessing a variety of psychological tests and by asking patients to rate their own QoL. The present study was undertaken to extend previous observations by asking patients to spontaneously select those domains of life experience that they think are most important in determining their quality of life. Sixty-eight medically stable CPD patients were asked to spontaneously select those three to five domains felt to be most important to them in defining their QoL. The 307 responses were then grouped into 22 broad categories by three investigators. The most frequently selected domains focused on interpersonal relationships. Domains that enhance the quality of one's day and add meaning to one's life were selected with a midrange frequency. Some domains that might intuitively seem to be important for a patient's QoL were selected with a surprisingly low frequency. These findings suggest that to understand what CPD patients value in assessing their QoL can best be determined by asking them directly and not by using predetermined variables.

Quality of life in peritoneal dialysis patients.

In 49 patients receiving continuous ambulatory peritoneal dialysis, we assessed the relative influences of adequacy of dialysis (assessed by kinetic transfer/volume urea) and psychological symptoms (depression and anxiety) upon the patients' evaluation of their overall quality of life (QoL). Subjects completed self-rating forms for anxiety, depressive, and somatic symptoms, for discrete areas relevant to QoL, and for overall QoL; clinicians also rated QoL. Depressive symptoms proved a much stronger correlate of overall QoL than did the biochemical measure of dialysis adequacy, and they remained influential even after adjustment for anxiety, kinetic transfer/volume, and somatic symptoms. In contrast, the effects of kinetic transfer/volume, anxiety symptoms, and somatic symptoms dropped sharply when adjusted for the other variables. Because psychological (especially depressive) symptoms may be stronger determinants of patients' overall QoL than is adequacy of dialysis, assessing QoL and psychological status should be part of the care of end-stage renal disease patients.

Sexual experience of the chronic peritoneal dialysis patient.

The actual and desired frequency of intercourse was studied in 68 randomly selected chronic peritoneal dialysis (CPD) patients. The results were correlated with standard measures of depression (Beck Depression inventory), anxiety (Patient Related Anxiety Scale), physical symptoms (Kupfer-Detre System 2), adequacy of dialysis (KT/Vurea) and nutrition (serum albumin level). In addition, patients assessed their quality of life (PAQOL) using an 1 to 10 analog scale. The mean +/- SD age of all patients studied was 54 +/- 11 yr, the mean dialysis duration was 24 +/- 24 months; 46% of the patients were female, and 34% were diabetic. Sixty-three percent of the patients reported never having intercourse (Group 1), 19% reported having intercourse < or = two times per month (Group II), and 18% reported having intercourse > two times per month (Group III). Dialysis duration, serum albumin level, KT/Vurea, and age were not significantly different among the three groups. Nearly 50% of patients in Group I desired to have intercourse, and 54% of the patients in Group II desired to have intercourse more frequently, Group I patients had significantly higher depression and anxiety scores, more physical symptoms, a poorer overall PAQOL, and less satisfaction with their sexual activity than Group III patients. These results suggest that there is a high prevalence of sexual difficulties in CPD patients. Patients not having intercourse have a poorer quality of life and higher degree of depression and anxiety than patients having intercourse more than two times per month.

Psychosocial factors and incidence of peritonitis.

It has been suggested that psychosocial (PS) factors may influence morbidity and mortality in chronically ill patients. However, investigators have not examined how PS factors affect specific medical problems in chronic peritoneal dialysis (CPD) patients. Sixty-eight patients maintained on CPD therapy were studied. PS testing included a self-rating form of patient-assessed quality of life (PaQOL), depression [Beck's Depression Inventory (BDI)], anxiety [Patient Rated Anxiety Scale (PRAS)], and assessment of physical symptoms (KDS-II). Peritonitis rates six months prior to PS assessment and six months after assessment were tabulated. The data show that during the study period patients with more than one episode of peritonitis compared to those with no episodes of peritonitis had: (1) significantly higher anxiety and physical symptom scores; (2) significantly lower PaQOL; and (3) higher depression scores, which did not reach statistical significance (p < 0.06). Whether higher peritonitis rates result in worse PS symptoms, or whether poor PS symptoms cause higher peritonitis rates needs to be determined with further investigations.

Cardiovascular effects of imipramine, fluvoxamine, and placebo in depressed outpatients.

BACKGROUND: The data presented represent cardiovascular parameters collected from one site of a larger, multicenter, double-blind, placebo-controlled, 6-week outpatient efficacy study of the serotonin uptake inhibitor fluvoxamine in depressed outpatients. METHOD: In this smaller study, we compared fluvoxamine (N = 17) to the prototypic antidepressant, imipramine (N = 14), and to placebo (N = 15). Specific parameters investigated were drug effects on postural pulse and blood pressure changes and ECG parameters including PR, QRS, and QTc intervals and ventricular heart rate. RESULTS: Fluvoxamine had few effects on measured parameters. Imipramine produced statistically significant changes on all measures; placebo had no effects on cardiac measures. CONCLUSION: Our data support that fluvoxamine, in a sample of healthy depressed outpatients, has little effect on cardiovascular function. Further study and clinical experience with this drug will be necessary before the full extent of its cardiac profile is known.

Teaching behavioral sciences to medical students. Education or training?

Accepted paradigms in medical behavioral science education are development, conflict and defense, and disease. Teaching under these paradigms blurs distinctions between preclinical and clinical education, and between education and training--most commonly by including an introduction to clinical psychiatry in preclinical courses. Such approaches may provide students with technical skills at the expense of their developing conceptual bases for continuing self-education. We developed a first-year behavioral sciences course using the paradigm of symbolic function and language. This paradigm can organize knowledge that underlies clinical skills involved in talking with patients and establishing an effective physician-patient relationship. Believing that fostering knowledge should be the primary goal of preclinical education, we emphasized primary sources and classics. Our goal was to encourage analysis and synthesis rather than memorization; evaluating such higher taxonomic levels of education is extraordinarily difficult.
