ABSTRACT

Introduction: Fatigue is a frequent and debilitating symptom that contributes to poor quality of life for people receiving peritoneal dialysis. Ecological momentary assessment using mobile technology (mEMA) is a novel survey technique that can collect symptom data in real-time and has not been trialed in a peritoneal dialysis cohort. The study aimed to explore real-time fluctuations and associations between fatigue, mood, and physical activity using mEMA. Methods: Adults receiving peritoneal dialysis completed fatigue and mood scales, via a mobile application (app), 5 times daily for 7 days and, concurrently wore an accelerometer. A feasibility questionnaire was completed on the eighth day. Results: Forty-eight adults completed the study. Within-day fatigue fluctuations were observed with severity lowest during mid-morning to early afternoon and peaking at bedtime. Associations between fatigue and mood were observed with a 1-unit change in mood score conferring a 5.2-unit change in fatigue (P < 0.01). Higher volume of physical activity was associated with lower fatigue and enhanced mood. Overall adherence to the app-based surveys was 73% with most participants reporting mobile phones and the mEMA app being easy to use. Conclusion: People receiving peritoneal dialysis experience within day and day-to-day fluctuations in fatigue that appear highly variable. Higher fatigue severity was associated with poorer mood and lower physical activity levels with future studies required to explore if physical activity-based interventions could be a potential strategy for the management of these symptoms. Furthermore, mEMA, and mobile phones, were feasible to capture symptom data with potential to be employed in future research or, as part of improved care.

ABSTRACT

BACKGROUND: Frequent blood glucose tests are performed for people with diabetes receiving haemodialysis. OBJECTIVES: To determine the rate of out-of-range post-haemodialysis blood glucose levels that are clinically acted upon, the intervention and outcome of each intervention, and the associations between post-haemodialysis blood glucose levels and relevant clinical predictors. DESIGN: 12-month retrospective cohort medical record review in one Australian haemodialysis centre. Post-haemodialysis blood glucose levels, prehaemodialysis blood glucose levels, time of treatment, diabetes medications, intradialytic fluid removal, dialysate dextrose concentration, clinical actions, interventions, and outcomes on out-of-range blood glucose levels were retrieved. PARTICIPANTS: 22 participants with a median time receiving dialysis 3.1 years (interquartile range 2.3-4.7). MEASUREMENTS AND RESULTS: The proportion of out-of-range post-haemodialysis blood glucose levels was 87.3% (95% confidence interval, 86.1%-88.5%). No out-of-range post-haemodialysis blood glucose levels were clinically acted upon. Out-of-range post-haemodialysis blood glucose levels were 4.6 times more likely if a higher dextrose bath was used (95% confidence interval: 3.3; 6.3. p < 0.001). The odds of the post-haemodialysis blood glucose levels increased by each 1 mmol/L. Intradialytic fluid removal, dialysate dextrose concentration, sex, dialysis time, anti-hyperglycaemic agents were also associated with out-of-range post-haemodialysis blood glucose levels. CONCLUSION: Routine post-haemodialysis blood glucose levels testing has limited clinical utility in care for people with diabetes receiving maintenance haemodialysis. Higher dextrose dialysate may require individual titration depending on prehaemodialysis blood glucose levels.

ABSTRACT

BACKGROUND: Patient activation refers to the knowledge, confidence and skills required for the management of chronic disease and is antecedent to self-management. Greater self-management in chronic kidney disease (CKD) results in improved patient experience and patient outcomes. AIM: To examine patient activation levels in people with CKD stage 5 pre-dialysis and determine associations with sociodemographic characteristics, treatment adherence and healthcare utilisation. METHODS/DESIGN: People with CKD stage 5 not receiving dialysis from one Australian kidney care service. Patient activation was measured using the 13-item Patient Activation Measure (PAM-13). Sociodemographic and clinical outcome data (emergency department visits, admissions) were collected from medical records. Morisky Medication Adherence Scale was used to determine self-report medication adherence. RESULTS: Two hundred and four participants completed the study. The mean PAM-13 score was 53.4 (SD 13.8), with 73% reporting low activation levels (1 and 2). Patient activation scores significantly decreased with increased age (P < 0.001) and significantly increased with higher educational levels (P < 0.001). Higher patient activation level was associated with fewer hospital emergency department visits (P = 0.03) and increased medication adherence (P < 0.001). CONCLUSION: Patient activation levels are low in people with CKD stage 5 not receiving dialysis suggesting limited ability for self-management and capacity for optimally informed decisions about their healthcare. Efforts to improve patient activation need to consider age and education level.

ABSTRACT

Introduction: Needle-related distress is common among people receiving hemodialysis and affects quality of life and treatment decisions, yet little evidence exists to guide management. This study explored patients' experiences of needle-related distress to inform the development of prevention, identification, and management strategies. Methods: Semistructured interviews concerning dialysis cannulation, needle-related distress, and potential solutions were conducted with people with current or recent experience of hemodialysis (N = 15) from a tertiary hospital-based service. Interviews ceased at thematic saturation. Transcripts were analyzed thematically. Results: There were 4 themes and 11 subthemes generated: (i) uncovering a hidden source of distress (dismissal and minimization by others; suffering in silence to stay alive; preparation, assessment, and education); (ii) coping with cannulation pain and trauma (interaction between physical damage, pain, and distress; operator dependency-the importance of nurse skill and technique); (iii) the environment created by dialysis nurses (emotional transference; communication during cannulation; valuing empathy and person-centered care; a psychosocially supportive dialysis unit); and (iv) supporting patient self-management of distress (accessing tools to help themselves; distraction to reduce distress). Conclusion: Needle-related distress is an often-hidden element of the hemodialysis experience. Patients learn to tolerate it as an inevitable part of dialysis for survival. Nurses' technical skills and the dialysis environment they create are key determinants of the patient cannulation experience. Proposed solutions include psychological screening, education for patients to self-manage distress, and training for nurses in communication and providing relevant psychological support.

ABSTRACT

BACKGROUND: A key skill of nephrology nursing is cannulation of patients receiving haemodialysis. Traumatic and unsuccessful cannulation experiences, particularly in the initial weeks of haemodialysis, may contribute to the onset of needle distress for patients. OBJECTIVES: To identify the key knowledge, skills and attitudes of nephrology nurses working with haemodialysis patients and the competencies relevant to nephrology nursing working with patients with needle-related distress. DESIGN: A qualitative study involving semistructured interviews. Interviews were audio-recorded, transcribed and deductive, and inductive thematic analysis applied. PARTICIPANTS: Nephrology nurses (n = 17) were interviewed from a tertiary kidney service in South Australia. Nurses had varying roles and years of experience (range 1-30 years) working with dialysis patients within the service. RESULTS: Two overarching themes, (1) Flexibility in Practice and Care and (2) Responsibility of Nephrology Nursing, were identified as relevant across all knowledge, skills and attitudes of nephrology nurses working with patients with needle-related distress. Thirty-six knowledge, skills and attitudes were identified; 12 related to knowledge, 14 related to skills and 10 were identified as attitudes and were summarised under seven broad competencies. CONCLUSION: This study identifies potential knowledge, skills and attitudes and competencies required for nephrology nurses working with patients with needle-related distress. It highlights strategies that may prevent the onset and worsening of needle-related distress, as well as reduce it. It also brings to light that nurses desire additional education regarding strategies to improve the patient experience of cannulation and nurse confidence and skill in this area.

ABSTRACT

BACKGROUND: Clinicians and patients have reported fragmentation in the primary and tertiary healthcare interface. However, perspectives of service navigation and the impacts of fragmentation are not well defined, particularly for patients transitioning to dialysis. This study aimed to define patient perspectives of the functioning of the health service interface and impacts on healthcare experiences and engagement, informing patient-centred and outcomes-focused service models. METHODS: A qualitative study was conducted through semi-structured interviews with 25 dialysis patients (16 males) aged 34-78 receiving dialysis across a multi-site tertiary service. Transcripts were analysed thematically. RESULTS: Three main themes were identified: (1) The Changing Nature of General Practitioner (GP) Patient Relationships; (2) Ownership and Leadership in Kidney Care; and (3) The Importance of Nephrologist-GP Communications. Patients perceived an unreliable primary-tertiary service interface which lacked coordinated care and created challenges for primary care continuity. These impacted perceptions of healthcare provider expertise and confidence in healthcare systems. Patients subsequently increased the healthcare sought from tertiary kidney clinicians. The fractured interface led some to coordinate communication between health sectors, to support care quality, but this caused additional stress. CONCLUSIONS: A fragmented primary-tertiary healthcare interface creates challenges for patient service navigation and can negatively impact patient experiences, leading to primary care disengagement, reduced confidence in health care quality and increased stress. Future studies are imperative for assessing initiatives facilitating health system integration, including communication technologies, healthcare provider training, patient empowerment, and specific outcomes in health, economic and patient experience measures, for patients transitioning to dialysis.

ABSTRACT

BACKGROUND: Chronic kidney disease (CKD) is a complex health condition that profoundly impacts an individual's general health and well-being throughout their entire lifetime. People with CKD require the knowledge, confidence, and skills to actively self-manage their health. This is referred to as patient activation. The efficacy of interventions to increase patient activation in the CKD population is unclear. AIM: This study aimed to examine the effectiveness of patient activation interventions on behavioral health-related outcomes among people with CKD stages 3-5. METHODS: A systematic review and meta-analysis of randomized controlled trials (RCTs) of patients with CKD stages 3-5 was performed. MEDLINE, EMCARE, EMBASE, and PsychINFO databases were searched between 2005 and February 2021. Risk of bias was assessed using the Joanna Bridge Institute critical appraisal tool. RESULTS: Nineteen RCTs that enrolled 4414 participants were included for synthesis. Only one RCT reported patient activation using the validated 13-item patient activation measure (PAM-13). Four studies demonstrated strong evidence that the intervention group developed a higher level of self-management compared to the control group (standardized mean differences [SMD] = 1.12, 95% CI [0.36, 1.87], p = .004). Eight RCTs led to a significant improvement in self-efficacy (SMD = 0.73, 95% CI [0.39, 1.06], p < .0001). There was weak to no evidence on the effect of the strategies shown on the physical component and mental components of health-related quality of life, and medication adherence. LINKING EVIDENCE TO ACTION: This meta-analysis highlights the importance of including tailored interventions using a cluster approach including patient education, goal setting with individualized action plan, and problem-solving to engage patients to be more actively involved in the self-management of their CKD.

ABSTRACT

BACKGROUND: Little is known about the prevalence and best management of needle fear in adults with chronic disease, who may experience frequent and long-term exposure to needles for lifesaving therapies such as renal dialysis and cancer treatment. Identifying interventions that assist in management of needle fear and associated distress is essential to support these patients with repeated needle and cannula exposure. METHOD: We followed the PRISMA methodology for scoping reviews and systematically searched PsychINFO, PubMed (MEDLINE), ProQuest, Embase and grey literature and reference lists between 1989 and October 2020 for articles related to needle discomfort, distress, anxiety, fear or phobia. The following chronic diseases were included: arthritis, asthma, chronic back pain, cancer, cardiovascular disease, chronic obstructive pulmonary disease, diabetes, and mental illness, or kidney failure. Literature concerning dentistry, vaccination, intravenous drug users and paediatric populations were excluded. RESULTS: We identified 32 papers reporting prevalence (n = 24), management (n = 5) or both (n = 3). Needle fear prevalence varied in disease cohorts: 17-52% (cancer), 25-47% (chronic kidney disease) and 0.2-80% (diabetes). Assessment methods varied across studies. Management strategies had poor evidence-base, but included needle-specific education, decorated devices, cognitive-behavioural stress management techniques, distraction, and changing the therapy environment or modality. CONCLUSION: Although needle fear is common there is a paucity of evidence regarding interventions to address it among adults living with chronic disease. This scoping review has highlighted the need for improved identification of needle fear in adults and development of interventions are required for these cohorts.

ABSTRACT

BACKGROUND: Gastrointestinal (GI) symptoms can present a significant burden to patients with chronic kidney disease (CKD) but the reported prevalence is inconsistent. OBJECTIVE: To examine the GI burden and dietary intake in patients with CKD with or without dialysis. METHODS: This was a cross-sectional study of 216 adults, recruited from outpatient and dialysis clinics, with CKD stage 4 or 5 not receiving dialysis (CKD-ND), or receiving haemodialysis (HD) or peritoneal dialysis (PD). Three questionnaires were administered: the Bristol Stool Form Scale (BSFS); a modified Gastrointestinal Symptom Rating Scale and a short Food Frequency Questionnaire. Outcomes were stool frequency and consistency, GI symptoms and dietary intake. RESULTS: Data were collected from 216 patients (mean age, 63 years [95% CI: 61, 65]; 63% males; CKD-ND: n = 134; HD: n = 67; PD: n = 15). Mean stool frequency for all groups was one bowel action per day (p = .45) and consistency was normal (BSFS type 4, p = .95). Overall GI symptom burden was low but several symptoms occurred at least "most of the time" including "tiredness/lethargy" (54% of participants), "reduced appetite" (29%), "early satiety" (25%) and "change in taste" (15%). Low intakes of fresh fruit, vegetables, whole-grains and legumes were found. No associations were observed between diet and GI symptoms. CONCLUSION: The overall GI symptom burden was low, but >15% of participants reported several symptoms as occurring most to all of the time. Low intakes of fresh fruit, vegetables, whole-grains and legumes were observed in all CKD patients.

ABSTRACT

INTRODUCTION: Fatigue is a frequent and debilitating symptom for people with end-stage kidney disease (ESKD) receiving dialysis. Ecological momentary assessment (EMA) allows real-time data capture of day-to-day and diurnal variations. EMA has been used to study haemodialysis-related fatigue but not in people receiving peritoneal dialysis who are unique in their physical, environmental and logistical characteristics. The aim of this study is to explore the real-time associations between fatigue and mood (EMA mobile application) and objective physical activity levels (accelerometry) in people with EKSD receiving peritoneal dialysis. METHOD: A 7-day intensive longitudinal study will be conducted. People receiving peritoneal dialysis within South Australia will be invited to participate. Five times throughout the day, participants will be prompted to answer 18 questions relating to fatigue (Visual Analogue Scale to Evaluate Fatigue Severity) and a single question for mood (Visual Analogue Mood Scale). Participants will continuously wear a GENEActiv accelerometer to capture physical activity levels during the 7-day period. At the completion of the data collection, participants will answer questions to evaluate the feasibility and acceptability of using EMA. DISCUSSION: This study will be the first to explore the real-time relationships between fatigue, mood and physical activity in people with ESKD receiving peritoneal dialysis. Understanding the fluctuations people experience and the relationships between mood and physical activity and fatigue will inform clinical management and well-being intervention development.

ABSTRACT

BACKGROUND: Arteriovenous fistula (AVF) management for haemodialysis (HD) is one of the most challenging aspects of clinical care. A successful cannulation outcome when an AVF or arteriovenous graft (AVG) is used for the first time can be influenced by many factors, including access maturity, staff skill, and patient factors. This study examined AVF/AVG outcomes at initiation of HD across two major metropolitan public hospitals. METHODS: Electronic medical records were reviewed to collect data retrospectively for a cohort of all newly commencing ESRD HD starts during 2018 to identify cannulation outcomes in the first 6 weeks. RESULTS: Of the 117 patients included, AVG use was low (5%). Twenty-four percent of patients required a surgical intervention to salvage a poorly functioning AVF prior to commencing HD. About 32.5% of the cohort had an uneventful start with all successful cannulations. For the remainder of the cohort the number of treatments with unsuccessful cannulation ranged from 1 to 4 or more. About 36% required a surgical intervention for a poorly functioning AVF after commencing HD. Commencing HD with a CVC is associated with a lower likelihood of subsequent successful cannulation (p < 0.001). CONCLUSION: Even in experienced centres, a subset of patients experienced complicated cannulation in the first 6 weeks of HD. Several areas of improvement could be considered for these patients; timely referral for access creation, post-operative surveillance to ensure AVF maturation inclusive of duplex ultrasonography, gentle induction using small gauge needles and low blood flows, and consideration of a single needle HD initiation pathway.

ABSTRACT

BACKGROUND: Identification of people with deteriorating health is essential for quality patient-centred care and optimal management. The Supportive and Palliative Care Indicators Tool (SPICT) is a guide to identifying people with deteriorating health for care planning without incorporating a prognostic time frame. OBJECTIVES: To improve renal nursing staff confidence in identifying patients approaching end-of-life and advocate for appropriate multidisciplinary care planning. DESIGN: This pilot feasibility prospective cohort study conducted in the renal ward of a major metropolitan health service during 2019 included a preintervention/postintervention survey questionnaire. A programme of education was implemented training staff to recognise end-of-life and facilitate appropriate care planning. RESULTS: Several domains in the postintervention survey demonstrated a statistically significant improvement in renal nurses' perception of confidence in their ability to recognise end of life. Of the 210 patients admitted during the study period, 16% were recognised as SPICT positive triggering renal physicians to initiate discussions about end-of-life care planning with patients and their families and to document a plan. Six months poststudy, 72% of those patients recognised as SPICT positive had died with a documented plan of care in place. CONCLUSION: The use of SPICT for hospital admissions and the application of education in topics related to end-of-life care resulted in a significant improvement in nurses' confidence in recognising deteriorating and frail patients approaching their end of life. The use of this tool also increased the number of deteriorating patients approaching end of life with goals of care documented.

ABSTRACT

INTRODUCTION: A functioning long-term vascular access is required for haemodialysis therapy; however, establishing this can be challenging in the setting of advanced age and vessels damaged by diabetes. Complications include the inability to insert two needles for the treatment resulting in miscannulation trauma and in some cases insertion of a temporary central venous access device. The broad objective of this review is to define the evidence base regarding cannulation practices in the initiation of haemodialysis via an arteriovenous fistula or an arteriovenous graft. METHODS: This review uses the framework recommended by the Joanna Briggs Institute and the process by which papers were included or excluded followed the standard Preferred Reporting Items for Systematic Reviews and Meta-Analyses group approach. A total of 20 primary research studies met the inclusion criteria. RESULTS: Cannulation in the 10- to 15-week period rather than delaying past this time frame is associated with the best outcomes. New vascular access given time to mature through single-needle haemodialysis treatments may improve long-term patency. Duplex ultrasound mapping prior to initiation of cannulation supports the clinical decision-making process on timing of and selection of cannulation sites. CONCLUSION: Cannulation trauma at the initiation of haemodialysis could potentially be reduced with a strategy of incremental haemodialysis using single-needle treatment supported with duplex ultrasonography assessment to 'map' the vascular access as a guide for clinicians prior to cannulation initiation.

ABSTRACT

BACKGROUND: Hypocalcaemia is increasingly recognized as a complication of denosumab use in Chronic Kidney Disease (CKD) patients with osteoporosis. Despite Therapeutic Goods Administration (TGA) notifications in 2013, we have subsequently encountered several cases of denosumab-induced hypocalcaemia, raising concern about lack of widespread awareness among prescribing practitioners. AIMS: We reviewed the morbidity and healthcare intervention needs of CKD patients with hypocalcaemia attributed to denosumab. METHODS: A retrospective case series of CKD patients with clinically significant hypocalcaemia after exposure to denosumab, encountered at the tertiary care referral hospital from December 2013 to February 2017, was undertaken. RESULTS: Eight patients (52-85 years of age) with stage 4-5 CKD developed clinically significant hypocalcaemia (corrected calcium 1.45±0.21mmol/L) following denosumab therapy for osteoporosis. Seven of the eight patients required inpatient management with three patients requiring intravenous calcium replacement and cardiac monitoring in a high dependency unit. Our study also identified additional factors that could potentially contribute to hypocalcaemia such as lack of calcium supplementation, use of noncalcium based phosphate binders, absence of or use of lower doses of calcitriol supplementation, low vitamin D levels, concomitant treatment with loop diuretics, history of parathyroidectomy, or presence of acute medical illness. CONCLUSION: Multiple cases of severe hypocalcaemia in CKD patients following denosumab exposure were encountered after TGA warnings, resulting in considerable morbidity and intensive healthcare interventions in CKD patients. We advocate greater awareness amongst the medical profession, careful consideration before using denosumab in CKD patients, and close follow-up after administration to prevent morbidity.

ABSTRACT

Green cincau (Premna oblongifolia Merr.) is a traditional food of Indonesia and provides a natural source of dietary fibre and antioxidants. This study evaluated the ability of green cincau, and other dietary fibres with or without the addition of anti-oxidant, epigallocatechin-3-gallate (EGCG), to prevent colorectal cancer in a 12 week azoxymethane (AOM) rat model. While all dietary treatments stimulated short chain fatty acid production (SCFA) in the digesta and faeces, no one treatment was able to significantly protect against aberrant crypt formation (ACF), when compared to the control diet. However, feeding green cincau leaves or extracts did not result in an increase in ACF compared to the control diet. Unexpectedly, when the dietary fibre source was pectin, 0.1% EGCG increased proliferative activity and liver lipid peroxidation when compared to the control diet containing cellulose. Examination of faecal microbial communities identified the presence of short chain acid producing bacteria, but a distinct community profile was not observed from any individual diet group. Overall, this research implies that combining dietary fibre with an antioxidant does not automatically equate to a beneficial response. Further work is required to investigate the health-promoting properties of green cincau.

ABSTRACT

SCOPE: Dietary supplementation with polyphenol-rich propolis can protect against experimentally induced colitis. We examined whether different polyphenol compositions of Chinese propolis (CP) and Brazilian propolis (BP) influence their ability to protect against dextran sulfate sodium (DSS)-induced colitis in rats. METHODS AND RESULTS: HPLC-DAD/Q-TOF-MS analysis confirmed that polyphenol compositions of CP and BP were dissimilar. Rats were given CP or BP by gavage (300 mg kg-1 body weight) throughout the study, starting 1 week prior to DSS treatment for 1 week followed by 3 d without DSS. CP and BP significantly reduced the colitis disease activity index relative to controls not receiving propolis, prevented significant DSS-induced colonic tissue damage, and increased resistance to DSS-induced colonic oxidative stress as shown by reduced malonaldehyde levels and increased T-AOC levels. CP and BP significantly reduced DSS-induced colonic apoptosis. Colonic inflammatory markers IL-1ß, IL-6, and MCP-1 were suppressed by CP and BP, whereas only BP-induced expression of TGF-ß. CP, not BP, increased the diversity and richness of gut microbiota populations. Both forms of propolis significantly reduced populations of Bacteroides spp. CONCLUSIONS: Despite the dissimilar polyphenol compositions of CP and BP, their ability to protect against DSS-induced colitis is similar. Nevertheless, some different physiological impacts were observed.

ABSTRACT

AIM: The aim of the present study was to describe the prevalence of all gastrointestinal (GI) symptoms reported by dialysis patients, as well as the tools being used for diagnosis. GI symptoms are commonly reported in patients having haemodialysis (HD) and peritoneal dialysis (PD), but there are multiple definitions and assessment tools reported in the literature. METHODS: A comprehensive systematic review was undertaken using five databases (Embase, Medline, CINAHL, Psycinfo and Web of Science) between 1996 and 2017. Articles were critically appraised using the Newcastle Ottawa Scale (NOS). Data collected were analyzed in a Microsoft Excel spreadsheet. RESULTS: Thirty studies (24 cross-sectional, six cohort) met the inclusion criteria. In total 5161 patients were studied (3804 HD and 1507 PD). Fifteen studies included HD, five included PD and 10 included both dialysis modalities. GI symptoms were heterogeneous, with the reported prevalence highly dependent on the definitions used, inclusion/exclusion criteria, assessment tools and methods used. The most prevalent symptoms were constipation, indigestion, abdominal pain and reflux. Medication use and dietary data were poorly reported. The most common tools used were Gastrointestinal Symptom Rating Scale (GSRS), Rome II and Rome III. Constipation was more common in HD patients than PD patients. Indigestion, abdominal pain and reflux were commonly reported in both dialysis modalities. CONCLUSIONS: Gastrointestinal symptoms are highly prevalent in people on dialysis; however, the evidence base is limited and further investigation of preventable causes and potential interventions such as medications and diet are required in future research.

ABSTRACT

BACKGROUND: The bowel health of those with chronic kidney disease (CKD) can be affected by medications, fluid/dietary allowances, reduced activity and pre-existing medical conditions. Patient perceptions of their bowel health can differ from those of health care professionals and the burden of gastrointestinal symptoms could be inaccurately reported. METHODS: Adults with CKD, including those undergoing haemodialysis, peritoneal dialysis and kidney transplant from four South Australian hospitals enrolled in the study. Participants completed a five-item questionnaire, to investigate their perception of bowel health compared with clinical criteria for 'normal and abnormal' bowel health using the Bristol Stool Form Scale, bowel frequency and reported symptoms. RESULTS: A total of 324 individuals completed the questionnaire. Of those with clinically defined 'abnormal' bowel health (n = 180), 50.6% perceived their bowels as 'normal' or 'more normal than abnormal'. Only 6% of this clinically 'abnormal' group perceived their bowel health as abnormal. Of those with clinically defined 'normal' bowel health (n = 144), 16% perceived their bowel health as 'abnormal', 'more abnormal than normal' or 'variable'. Fifty-seven percent of patients with clinically defined 'abnormal' bowel health were not taking any treatments. Peritoneal dialysis recipients were the highest users of treatments to improve bowel function, with 62% using 1 or more treatment. CONCLUSIONS: It is common for patients with CKD to experience signs and symptoms of abnormal bowel health. There is a disconnect between patient perceptions and clinical definitions of normal or abnormal bowel health. Clinical care team members must carefully obtain and clarify patient-reported symptoms related to bowel function in order to help ensure recommendations and use of appropriate treatments.
