Health care management strategies of long-term dialysis survivors.

This qualitative, exploratory-descriptive study describes self-management strategies of long-term survivors of dialysis. Data were collected via long, semi-structured interviews with 18 individuals, 10 male and 8 female, who had been on dialysis for more than 15 years. Of these, 10 participants were Caucasian, 4 were African-American, and 4 were Hispanic. Respondents ranged in age from 38 to 63 years. Interviews were audio-recorded, and verbatim transcriptions of interviews were analyzed according to a content analytic procedure, with movement from specific to general. Six broad patient self-management strategies were identified: impression management, selective symptom report/management, vigilant oversight of care, self-proposal of treatments, active self-advocacy, and independent adoption of treatments/use of alternative therapies. For the individuals interviewed, self-management was largely constituted as management of the health care system and health care providers who represent it. Although the small sample size and the exploratory-descriptive methodology limit generalizability, valuable insights into techniques for self-management were derived. Such insights pave the way for future research into characteristics that distinguish dialysis patients who have the potential to be effective self-managers. More importantly, understanding of successful self-management by individuals on dialysis lays the groundwork for development of interventions to help other patients develop similar positive self-management strategies.

Self-reported functional status: an important predictor of health outcomes among end-stage renal disease patients.

A contemporary focus on outcomes assessment has provided affirmation that patient functional status is both an important outcome of medical care and an important predictor of longer term outcomes such as morbidity and/or mortality. Monitoring functional status among end-stage renal disease (ESRD) patients is particularly critical because the cycle of physical deconditioning experienced by renal patients is both insidious and malignant. Over the past several years, patient self-report instruments have been used with increasing frequency to assess functioning. Among ESRD patients, such self-reports have reliably predicted mortality and some morbidity. Additionally, renal patients' self-reported functioning is also correlated with the results of several commonly performed laboratory tests. Based on these findings, measures of self-reported functional status might be considered a practical adjunct to regular patient assessments. They could be routinely used for purposes that might include: identifying the particular areas of functioning and well-being that need improvement; screening for subtle changes in health status; establishing physical status baselines; and corroborating the effectiveness of physical activity interventions. Overall, ESRD patients' self-report of their functioning appears to secure, synthesize, and standardize data about patient health status that is unavailable through any other mechanism. Such information may be essential to medicine's primary missions of promoting health and preserving life.

Hemodialysis patients' noncompliance with oral medications.

The purpose of this study was to describe the prevalence, severity, and patterns of noncompliance with prescribed medications among hemodialysis patients; and to identify patient, disease and/or treatment characteristics associated with noncompliance. Demographic and medical history information were collected from chart reviews and patient interviews. Compliance data were collected via self-report, pill count, and a medication event monitoring system (MEMS, Product of Aprex, a division of Apria Healthcare; Costa Mesa, CA). A total of 135 hemodialysis patients from 11 dialysis facilities in a large Midwestern metropolitan area participated. Overall, medication compliance rates were very low. Of the patient, disease, and treatment characteristics considered, only race was found to be associated with patient noncompliance; African-American patients had higher rates of noncompliance with both monitored medications. The results of this study confirm that noncompliance with medication regimens continues to be an unremitting problem for hemodialysis patients and that demographic, medical history, and treatment characteristics do not adequately explain this behavior. Also, estimates of patient compliance as measured by self-report, pill count, and microelectronic monitoring are disparate enough to suggest that relying exclusively on patients' self-report of compliance might be insufficient.

Differences in older versus younger hemodialysis patients' noncompliance with oral medications.

Hemodialysis patients' compliance with their therapeutic regimens, including dietary and fluid restrictions, dialysis treatments and medications, is generally suboptimal. Recently, the mean age of the dialysis population has increased. Since impaired cognitive function, which sometimes accompanies aging, interferes with the ability to comprehend instructions, elderly dialysis patients might be at greater risk for noncompliance than are their younger counterparts. In this project, 135 hemodialysis patients (68 patients > 65 years of age and 67 patients < or = 65 years) were studied. Rates of noncompliance with oral antihypertensives and phosphate binders, as tracked by a medication event monitoring system (MEMS), are reported here. More than 42% of older patients (> 65) and 47% of younger patients (< or = 65) were repeated noncompliers with antihypertensives, missing at least 20% of the prescribed doses. Similarly, 65% of older patients and 80% of younger patients exhibited repeated noncompliance with phosphate binders. Almost 30% of older patients and more than 32% of younger patients missed their antihypertensives completely on 20% or more of the prescribed days. Only 18% of the older subjects, but 33% of younger patients missed taking their phosphate binders for 20 or more percent of the prescribed days. Rates of noncompliance were found to differ between the two populations of patients in that younger patients made significantly more dosing errors with their antihypertensives and missed taking their phosphate binders on more days than did their older counterparts.

Differences between employed and nonemployed dialysis patients.

Three hundred fifty-nine chronic dialysis patients (85 employed and 274 nonemployed) were surveyed to identify/verify those characteristics which differentiate between employed versus nonemployed status. Education emerged as a significant correlate of employment, as noted by previous investigators, whereas, unlike previous research, neither mode of dialysis, length of time on dialysis, number of comorbid conditions, nor cause of renal failure (eg, diabetes) were associated with employment status. Measures of functional status (MOS SF-20 and Karnofsky) were positively associated with employment. Furthermore, patients' perceptions that their health limited the type and amount of work that they could do were negatively associated with employment. In addition, using a series of de novo items, we found subjects' beliefs about dialysis patients' ability to work to be a "self-fulfilling prophecy" with regard to employment status. That is, patients who themselves believed that dialysis patients should work and had this notion reinforced by significant others were more likely to be employed. Interestingly, 21 percent of unemployed patients reported that they were both able to work and wanted to return to work. Because it is consistently reported that only a small percentage of dialysis patients are employed, targeting the patients who are both willing and able to work for vocational rehabilitation might significantly increase the numbers of employed dialysis patients.
