Hemodialysis patients’ preferences for the management of secondary hyperparathyroidism

Abstract Background Patient engagement and patient-centered care are critical in optimally managing patients with end-stage renal disease (ESRD). Understanding patient preferences is a key element of patient-centered care and shared decision making. The objective of this study was to elicit patients’ preferences for the treatment of secondary hyperparathyroidism (SHPT) associated with ESRD using a discrete-choice experiment survey. Methods Clinical literature, nephrologist input, patient-education resources, and a patient focus group informed development of the survey instrument, which was qualitatively pretested before its administration to a broader sample of patients. The National Kidney Foundation invited individuals in the United States with ESRD who were undergoing hemodialysis to participate in the survey. Respondents chose among three hypothetical SHPT treatment alternatives (two medical alternatives and surgery) in each of a series of questions, which were defined by attributes of efficacy (effect on laboratory values and symptoms), safety, tolerability, mode of administration, and cost. The survey instrument included a best-worst scaling exercise to quantify the relative bother of the individual attributes of surgery. Random-parameters logit models were used to evaluate the conditional relative importance of the attributes. Results A total of 200 patients with ESRD completed the survey. The treatment attributes that were most important to the respondents were whether a treatment was a medication or surgery and out-of-pocket cost. Patients had statistically significant preferences for efficacy attributes related to symptom management and laboratory values, but placed less importance on the attributes related to mode of administration and side effects. The most bothersome attribute of surgery was the risk of surgical mortality. Conclusions Patients with ESRD and SHPT who are undergoing hemodialysis understand SHPT and have clear and measurable treatment preferences. These results may help inform clinicians about patients’ preferences regarding treatment options for a common complication of ESRD

Hemodialysis patients’ preferences for the management of anemia

Abstract Background Patient engagement in end-stage renal disease (ESRD) is expected to result in a more patient-centered approach to care that aligns with patients’ values, preferences, and goals for treatment. Nevertheless, no previous studies of which we are aware have evaluated patients’ benefit-risk preferences for the management of anemia associated with ESRD. The primary objective of this study was to quantify the tradeoffs patients are willing to make between cardiovascular risks associated with some anemia medicines and red blood cell (RBC) transfusions. A secondary objective was to quantify the importance of avoiding transfusion-related risks. Methods A survey instrument was developed from the clinical literature, clinician input, patient-education resources, and a patient focus group. The survey instrument was qualitatively pretested before its administration to a broader sample of patients. The National Kidney Foundation invited individuals in the United States to participate in the survey. In a discrete-choice experiment (DCE), respondents chose between two hypothetical anemia medications in a series of questions. Each medication was defined by symptom relief, frequency of transfusions, cardiovascular risk, mode of administration, and out-of-pocket cost. The survey also included a best-worst scaling (BWS) exercise to quantify the importance of avoiding attributes of blood transfusions. Results from the DCE were used to estimate relative importance and marginal willingness to pay. Results from the BWS were converted to relative importance weights. Results A total of 200 individuals completed the survey. Patients were willing to accept a 6% medication-related risk of heart attack to avoid having two RBC transfusions per month. Symptom relief and mode of administration were of moderate importance. The most important transfusion-related risk to avoid was transfusion-related lung injury. Conclusions Patients with ESRD and anemia have measurable treatment preferences and are willing to accept risks associated with anemia medications to avoid transfusions
