Although several studies have found that the burden of symptoms in patients who are on maintenance hemodialysis is substantial, little is known about renal providers' awareness of these symptoms. The aim of this study was to assess renal provider recognition of symptoms and their severity in hemodialysis patients.
DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The Dialysis Symptom Index, a 30-item measure of symptoms and their severity, was administered to patients during a routine hemodialysis session. Immediately after surveying patients, the renal provider who evaluated the patient completed the Dialysis Symptom Index to report the symptoms that he or she believed were present in that patient. Sensitivity, specificity, and positive and negative predictive values of provider reports of symptoms were calculated using patient reports as the reference standard. Patient-provider agreement on the presence and severity of symptoms was assessed using the kappa statistic.
Surveys were completed by 75 patients and 18 providers. For 27 of 30 symptoms, the sensitivity of provider responses was <50%, and provider responses for 25 symptoms were characterized by positive predictive values of <75%. kappa scores for 25 symptoms including those pertaining to pain, sexual dysfunction, sleep disturbance, and psychologic distress were <0.20, indicating poor provider recognition of these symptoms. Providers underestimated the severity of 19 of 30 symptoms.
Renal providers are largely unaware of the presence and severity of symptoms in patients who are on maintenance hemodialysis. Implementation of a standardized symptom assessment process may improve provider recognition of symptoms and promote use of symptom-alleviating treatments.
尽管多项研究发现维持性血液透析患者的症状负担较重,但对于肾脏科医护人员对这些症状的认知情况却知之甚少。本研究的目的是评估肾脏科医护人员对血液透析患者症状及其严重程度的识别情况。
设计、场所、参与者及测量方法:在常规血液透析过程中,使用包含30个项目的透析症状指数来评估患者的症状及其严重程度。在对患者进行调查后,立即让评估该患者的肾脏科医护人员完成透析症状指数,以报告其认为该患者存在的症状。以患者报告作为参考标准,计算医护人员症状报告的敏感性、特异性、阳性预测值和阴性预测值。使用kappa统计量评估患者与医护人员在症状存在与否及严重程度方面的一致性。
75名患者和18名医护人员完成了调查。对于30种症状中的27种,医护人员回答的敏感性<50%,25种症状的医护人员回答的阳性预测值<75%。包括与疼痛、性功能障碍、睡眠障碍和心理困扰相关症状在内的25种症状的kappa评分<0.20,表明医护人员对这些症状的识别较差。医护人员低估了30种症状中19种症状的严重程度。
肾脏科医护人员在很大程度上未意识到维持性血液透析患者症状的存在及其严重程度。实施标准化的症状评估流程可能会提高医护人员对症状的识别,并促进使用缓解症状的治疗方法。
