This study is seeking to identify the most effective strategy to manage pain, sexual dysfunction, and depression in patients receiving chronic hemodialysis therapy.

OBJECTIVES: There are currently over 500,000 individuals with end-stage renal disease (ESRD) in the United States, and more than 100,000 new patients develop this condition annually. Recent estimates suggest that more than 35,000 veterans currently receive chronic hemodialysis. Although life-sustaining, hemodialysis is associated with substantial morbidity and mortality. Numerous studies have sought to identify interventions that reduce the mortality of patients dependent on hemodialysis, yet recent clinical trials of dialysis dose, dialysis membrane, and lipid lowering therapy have failed to demonstrate survival benefits. With the recognition that providers have limited means beyond renal transplantation to prolong the lives of patients on hemodialysis, investigators are beginning to refocus their research efforts on identifying interventions to improve patients' quality of life, which is substantially impaired in this population. Several major factors that contribute to poor quality of life have been identified, including the large burden of physical and emotional symptoms in this patient population. Of the many symptoms that affect patients on hemodialysis, pain, sexual dysfunction, and depression are among the most prevalent, severe, and highly correlated with impaired quality of life. These observations are particularly noteworthy with recent data documenting the safety and efficacy of pharmacologic therapy for these symptoms. Nonetheless, preliminary studies suggest that even when severe, these symptoms are untreated or under-treated in patients on hemodialysis. The reasons for the sub-optimal treatment have not been clearly elucidated, but the investigators research demonstrated that renal providers are largely unaware of the presence and severity of pain, sexual dysfunction, and depression in their hemodialysis patients. Although increasing provider awareness of these symptoms would seem to be important for the provision of therapy, it is not clear that simply informing clinicians would be sufficient to improve treatment. The broad objective of this 3-year project is to determine the most effective strategy for the management of pain, sexual dysfunction, and depression in patients on chronic hemodialysis. The investigators postulate that merely informing renal providers of patients' pain, sexual dysfunction, and depression and providing them with evidence-based treatment algorithms will not significantly improve the management of these symptoms. Rather, optimal symptom management will require assessment and treatment of these symptoms by a dedicated renal symptom management nurse. In a randomized clinical trial of not more than 350 patients receiving hemodialysis at 9 dialysis units, the investigators will compare two symptom management strategies: (a) providing feedback on patients' symptoms to renal providers along with evidence-based algorithms for their treatment and; (b) using a renal symptom management nurse to identify and facilitate treatment of these symptoms. This study involves the nurse and the research assistant bringing treatment plans and algorithms to the attention of the renal providers and does not involve any treatment by the research assistant and nurse themselves. By determining the most effective approach to the management of overall pain, sexual dysfunction, and depression, the investigators hope to introduce a patient-centered management approach to improve the quality of life of patients receiving chronic hemodialysis. METHODS: Overview of Study Design The investigators have proposed a randomized, clinical trial to compare two strategies for the treatment of pain, sexual dysfunction, and depression in patients on chronic hemodialysis. The investigators have recruited 315 patients from nine local VA and non-VA dialysis units. After enrollment, baseline data was collected from 289 patients, and an observation period of at least 2 months but not longer than 12 months ensued. Pain, sexual dysfunction, and depression were assessed monthly during this observation period, which allowed us to establish the stability of symptoms in study patients and obtain a valid estimate of the impact of the investigators interventions on these domains. Additionally, quality of life, overall symptom burden and satisfaction with care was assessed every 3 months. The investigators assessment of sexual function focused on ED in men, and decreased libido, arousal, dyspareunia, and satisfaction in women. The investigators also conducted monthly assessments of patients' attendance at dialysis, compliance with treatment duration, emergency room visits, and hospitalizations. After the observational phase, the investigators launched a 12-month intervention phase to compare two interventions. During this phase, the investigators continue these same assessments of pain, sexual dysfunction, depression, quality of life, overall symptom burden and satisfaction with care. The investigators continue to track attendance and compliance with dialysis, emergency room visits, and hospitalizations on a monthly basis. Patients are randomized into one of two study arms by day of dialysis treatment (Monday, Wednesday, and Friday versus Tuesday, Thursday, and Saturday). Sites that only treat patients on a Monday/Wednesday/Friday dialysis schedule are randomized by the time of the dialysis shift within the day, patients on the a.m. shift are randomized to one arm of the study and those on the p.m. shift to the other. One group is randomized to a feedback intervention in which renal providers will receive data on the presence and severity of patients' pain, sexual dysfunction, and depression along with algorithms for the treatment of these symptoms (For sexual dysfunction, providers will receive a treatment algorithm for ED and a recommendation to refer women with this symptom for gynecologic care). Treatment decisions will be left at the discretion of the provider(s). The other group has a renal symptom management nurse assess and facilitate the treatment of pain, sexual dysfunction, and depression (management intervention).In this arm, treatment of sexual dysfunction in men will focus on ED, while the symptom management nurse will facilitate referral of women with sexual dysfunction for gynecological care given the lack of pharmacologic therapy. Study Status: Intervention Phase is completed, analysis is ongoing.
