Could symptom burden predict subsequent healthcare use in patients with end stage kidney disease on hemodialysis care? A prospective, preliminary study

Patient-Reported Outcome Measures for Patients With CKD: The Case for Patient-Reported Outcomes Measurement Information System (PROMIS) Tools

Chronic kidney disease (CKD), kidney failure, and kidney replacement therapies are associated with high symptom burden and impaired health-related quality of life (HRQOL). Symptoms change with disease progression or transition between treatment modalities and frequently go unreported and unmanaged. Tools that reliably monitor symptoms may improve the management of patients with CKD. Patient-reported outcome measures (PROMs) assess symptom severity; physical, psychological, social, and cognitive functioning; treatment-related side effects; and HRQOL. Systematic use of PROMs can improve patient-provider communication, patient satisfaction, clinical outcomes, and HRQOL. Potential barriers to their use include a lack of engagement, response burden, and limited guidance about PROM collection, score interpretation, and workflow integration. Well-defined, acceptable, and effective clinical response pathways are essential for implementing PROMs. PROMs developed by the Patient-Reported Outcomes Measurement Information System (PROMIS) address some challenges and may be suitable for clinical use among patients with CKD. PROMIS tools assess multiple patient-valued, clinically actionable symptoms and functions. They can be administered as fixed-length, customized short forms or computer adaptive tests, offering precise measurement across a range of symptom severities or function levels, tailored questions to individuals, and reduced question burden. Here we provide an overview of the potential use of PROMs in CKD care, with a focus on PROMIS.

Symptom Science in Kidney Disease

Physical and emotional symptoms are highly prevalent among patients with kidney disease and are directly linked to impaired health-related quality of life. Symptom science is a field of research aimed at advancing knowledge of the holistic mechanisms driving symptoms, how best to assess symptoms accurately, and developing novel and patient-centered approaches to symptom management. Patients with kidney disease have identified symptom science as a top research priority, and opportunities abound for ongoing patient engagement in symptom-related research efforts and clinical care. This review describes the burden of symptoms experienced by patients with kidney disease, explores the spectrum of patient engagement in symptom care and research, and discusses approaches for symptom assessment and management, taking into consideration the multitude of factors that may contribute to symptoms.

Predicting return of lung function after a pulmonary exacerbation using the cystic fibrosis respiratory symptom diary-chronic respiratory infection symptom scale

Background

Pulmonary exacerbations (PExs) in people with cystic fibrosis (PwCF) are associated with increased healthcare costs, decreased quality of life and the risk for permanent decline in lung function. Symptom burden, the continuous physiological and emotional symptoms on an individual related to their disease, may be a useful tool for monitoring PwCF during a PEx, and identifying individuals at high risk for permanent decline in lung function. The purpose of this study was to investigate if the degree of symptom burden severity, measured by the Cystic Fibrosis Respiratory Symptom Diary (CFRSD)- Chronic Respiratory Infection Symptom Scale (CRISS), at the onset of a PEx can predict failure to return to baseline lung function by the end of treatment.

Methods

A secondary analysis of a longitudinal, observational study (N = 56) was conducted. Data was collected at four time points: year-prior-to-enrollment annual appointment, termed "baseline", day 1 of PEx diagnosis, termed "Visit 1", day 10-21 of PEx diagnosis, termed "Visit 2" and two-weeks post-hospitalization, termed "Visit 3". A linear regression model was performed to analyze the research question.

Results

A regression model predicted that recovery of lung function decreased by 0.2 points for every increase in CRISS points, indicating that participants with a CRISS score greater than 48.3 were at 14% greater risk of not recovering to baseline lung function by Visit 2, than people with lower scores.

Conclusion

Monitoring CRISS scores in PwCF is an efficient, reliable, non-invasive way to determine a person's status at the beginning of a PEx. The results presented in this paper support the usefulness of studying symptoms in the context of PEx in PwCF.

"You need a team": perspectives on interdisciplinary symptom management using patient-reported outcome measures in hemodialysis care-a qualitative study

BACKGROUND

Patient-reported outcome measures (PROMs) are standardized instruments used for assessing patients' perspectives on their health status at a point in time, including their health-related quality of life, symptoms, functionality, and physical, mental, and social wellbeing. For people with kidney failure receiving hemodialysis, addressing high symptom burden and complexity relies on care team members integrating their expertise to achieve common management goals. In the context of a program-wide initiative integrating PROMs into routine hemodialysis care, we aimed to explore patients' and clinicians' perspectives on the role of PROMs in supporting interdisciplinary symptom management.

METHODS

We employed a qualitative descriptive approach using semi-structured interviews and observations. Eligible participants included adult patients receiving intermittent, outpatient hemodialysis for > 3 months, their informal caregivers, and hemodialysis clinicians (i.e., nurses, nephrologists, and allied health professionals) in Southern Alberta, Canada. Guided by thematic analysis, team members coded transcripts in duplicate and developed themes iteratively through review, refinement, and discussion.

RESULTS

Thirty-three clinicians (22 nurses, 6 nephrologists, 5 allied health professionals), 20 patients, and one caregiver participated in this study. Clinicians described using PROMs to coordinate care across provider types using the resources available in their units, whereas patients tended to focus on the perceived impact of this concerted care on symptom trajectory and care experience. We identified 3 overarching themes with subthemes related to the role of PROMs in interdisciplinary symptom management in this setting: (1) Integrating care for interrelated symptoms ("You need a team", conducive setting, role clarity and collaboration); (2) Streamlining information sharing and access (symptom data repository, common language for coordinated care); (3) Reshaping expectations (expectations for follow-up, managing symptom persistence).

CONCLUSIONS

We found that use of PROMs in routine hemodialysis care highlighted symptom interrelatedness and complexity and helped to streamline involvement of the interdisciplinary care team. Issues such as role flexibility and resource constraints may influence sustainability of routine PROM use in the outpatient hemodialysis setting.

Symptom Burden Is Associated with Increased Emergency Department Utilization among Patients with Cirrhosis

Background: Patients with cirrhosis have significant morbidity and mortality, as well as substantial symptom burden. Objective: We investigated the relationship between symptom burden and inpatient health care utilization among patients with cirrhosis. Methods: Adult patients with cirrhosis being evaluated for or awaiting liver transplantation at an academic institution in the United States completed the Edmonton Symptom Assessment Scale (ESAS), a validated symptom evaluation tool with total scores ranging from 0 to 90. The outcomes of interest were emergency department (ED) visits, nonelective hospitalizations, hospital days, intensive care unit (ICU) admissions, and 30-day readmissions within 6 months. Adjusted incidence rate ratios (IRRs) were used to examine the relationship between ESAS scores and outcomes. Results: Of 233 patients (43% female, median age 61), the median total ESAS score was 16 (interquartile range 6-30). Higher total scores on the ESAS were associated with increased ED visits, hospitalizations, hospital days, and ICU days (all p < 0.04). After adjusting for age, gender, and Model for End-Stage Liver Disease-sodium, ESAS total score remained an independent predictor of ED visits (IRR 1.05, confidence interval [95% CI] 1.00-1.10, p = 0.03). Multivariate ESAS subscale analyses revealed that the physical symptom score was associated with ED visits (IRR 1.09, 95% CI 1.02-1.16, p = 0.01), but the psychological symptom score was not (IRR 1.03, 95% CI 1.00-1.08, p = 0.15). Conclusions: Patient-reported symptoms, particularly physical symptoms, are independently associated with ED visits among patients with cirrhosis being considered for liver transplantation. Further research is needed to examine whether addressing symptoms more aggressively, such as with palliative care co-management, could decrease ED utilization in this population.

Patient-centred approaches for the management of unpleasant symptoms in kidney disease

Patients with chronic kidney disease (CKD) frequently experience unpleasant symptoms. These can be gastrointestinal (constipation, nausea, vomiting and diarrhoea), psychological (anxiety and sadness), neurological (lightheadedness, headache and numbness), cardiopulmonary (shortness of breath and oedema), dermatological (pruritus and dry skin), painful (muscle cramps, chest pain and abdominal pain) or involve sexual dysfunction, sleep disorders and fatigue. These symptoms often occur in clusters, with one of them as the lead symptom and others as secondary symptoms. Uraemic toxins (also called uremic toxins) are often considered to be the main cause of CKD-associated symptom burden, but treatment of uraemia by dialysis often fails to resolve them and can engender additional symptoms. Indeed, symptoms can be exacerbated by comorbid conditions, pharmacotherapies, lifestyle and dietary regimens, kidney replacement therapy and ageing. Patients with kidney disease, including those who depend on dialysis or transplantation, should feel actively supported in their symptom management through the identification and targeting of unpleasant symptoms via a tailored palliative care approach. Such an approach may help minimize the burden and consequences of kidney disease, and lead to improved patient outcomes including health-related quality of life and better life participation.

Zolpidem Versus Trazodone Initiation and the Risk of Fall-Related Fractures among Individuals Receiving Maintenance Hemodialysis

BACKGROUND AND OBJECTIVES

Zolpidem, a nonbenzodiazepine hypnotic, and trazodone, a sedating antidepressant, are the most common medications used to treat insomnia in the United States. Both drugs have side effect profiles (e.g., drowsiness, dizziness, and cognitive and motor impairment) that can heighten the risk of falls and fractures. Despite widespread zolpidem and trazodone use, little is known about the comparative safety of these medications in patients receiving hemodialysis, a vulnerable population with an exceedingly high fracture rate.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

Using data from the United States Renal Data System registry (2013-2016), we conducted a retrospective cohort study to investigate the association between the initiation of zolpidem versus trazodone therapy and the 30-day risk of hospitalized fall-related fractures among Medicare-enrolled patients receiving maintenance hemodialysis. We used an active comparator new-user design and estimated 30-day inverse probability of treatment-weighted hazard ratios and risk differences. We treated death as a competing event.

RESULTS

A total of 31,055 patients were included: 18,941 zolpidem initiators (61%) and 12,114 trazodone initiators (39%). During the 30-day follow-up period, 101 fall-related fractures occurred. Zolpidem versus trazodone initiation was associated with a higher risk of hospitalized fall-related fracture (weighted hazard ratio, 1.71; 95% confidence interval, 1.11 to 2.63; weighted risk difference, 0.17%; 95% confidence interval, 0.07% to 0.29%). This association was more pronounced among individuals prescribed higher zolpidem doses (hazard ratio, 1.85; 95% confidence interval, 1.10 to 3.01; and risk difference, 0.20%; 95% confidence interval, 0.04% to 0.38% for higher-dose zolpidem versus trazodone; and hazard ratio, 1.60; 95% confidence interval, 1.01 to 2.55 and risk difference, 0.14%; 95% confidence interval, 0.03% to 0.27% for lower-dose zolpidem versus trazodone). Sensitivity analyses using longer follow-up durations yielded similar results.

CONCLUSIONS

Among individuals receiving maintenance hemodialysis, zolpidem initiators had a higher risk of hospitalized fall-related fracture compared with trazodone initiators.
