The Association Between Intradialytic Symptom Clusters and Recovery Time in Patients Undergoing Maintenance Hemodialysis: An Exploratory Analysis.

ABSTRACT:

Background

Individuals receiving hemodialysis often experience concurrent symptoms during treatment and frequently report feeling unwell after dialysis. The degree to which intradialytic symptoms are related, and which specific symptoms may impair health-related quality of life (HRQoL) is uncertain.

Objectives

To explore intradialytic symptoms clusters, and the relationship between intradialytic symptom clusters with dialysis treatment recovery time and HRQoL.

Design/setting

We conducted a post hoc analysis of a prospective cohort study of 118 prevalent patients receiving hemodialysis in two centers in Calgary, Alberta and Hamilton, Ontario, Canada.

Participants

Adults receiving hemodialysis treatment for at least 3 months, not scheduled for a modality change within 6 weeks of study commencement, who could provide informed consent and were able to complete English questionnaires independently or with assistance.

Methods

Participants self-reported the presence (1 = none to 5 = very much) of 10 symptoms during each dialysis treatment, the time it took to recover from each treatment, and weekly Kidney Disease Quality of Life 36-Item-Short Form (KDQoL-36) assessments. Principal component analysis identified clusters of intradialytic symptoms. Mixed-effects, ordinal and linear regression examined the association between symptom clusters and recovery time (categorized as 0, >0 to 2, >2 to 6, or >6 hours), and the physical component and mental component scores (PCS and MCS) of the KDQoL-36.

Results

One hundred sixteen participants completed 901 intradialytic symptom questionnaires. The most common symptom was lack of energy (56% of treatments). Two intradialytic symptom clusters explained 39% of the total variance of available symptom data. The first cluster included bone or joint pain, muscle cramps, muscle soreness, feeling nervous, and lack of energy. The second cluster included nausea/vomiting, diarrhea and chest pain, and headache. The first cluster (median score: -0.56, 25th to 75th percentile: -1.18 to 0.55) was independently associated with longer recovery time (odds ratio [OR] 1.62 per unit difference in score, 95% confidence interval [CI]: 1.23-2.12) and decreased PCS (-0.72 per unit difference in score, 95% CI: -1.29 to -0.15) and MCS scores (-0.82 per unit difference in score, 95% CI: -1.48 to -0.16), whereas the second cluster was not (OR 1.24, 95% CI: 0.97-1.58; PCS 0.19, 95% CI -0.46 to 0.83; MCS -0.72, 95% CI: -1.50 to 0.06).

Limitations

This was an exploratory analysis of a small data set from 2 centers. Further work is needed to externally validate these findings to confirm intradialytic symptom clusters and the generalizability of our findings.

Conclusions

Intradialytic symptoms are correlated. The presence of select intradialytic symptoms may prolong the time it takes for a patient to recover from a dialysis treatment and impair HRQoL.

Project description:ObjectivePatients undergoing hemodialysis (HD) have high protein and energy requirements, and protein-energy wasting is common and associated with poor outcomes. Eating during dialysis may improve nutritional status by counteracting the catabolic effects of HD treatment; but eating during HD may be discouraged because of concerns of postprandial hypotension. However, little data are available to support this practice. In this study, we hypothesized that high-protein meals during HD do not lead to symptomatic intradialytic hypotension events.DesignA 9-week, nonrandomized, parallel-arm study.SettingA single in-center HD clinic.SubjectsEighteen patients undergoing HD from 2 shifts completed the study. Patients were aged 62 ± 16 years with dialysis vintage of 3.4 ± 2.6 years.InterventionPatients in the intervention group (n = 9) undergoing HD received meals of ∼30 g protein and ∼1/3 daily recommended intakes of sodium, potassium, phosphorus, and fluid during dialysis for 25 consecutive HD sessions. The control group (n = 9) completed all aspects of the study including a visit by study personnel but were not given meals. The 25 consecutive sessions before the start of the intervention/control phase were used as a baseline comparison for each patient.Main outcome measureSymptomatic hypotension event frequency.ResultsIn the intervention arm, there were 19 symptomatic hypotension events in 5 patients prestudy and 18 events in 6 patients during the study. In the control arm, there were 16 events in 7 patients prestudy and 13 events in 7 patients during the study. Change in the frequency of symptomatic hypotension events from prestudy to during study was not different between groups (P = .71). There was no effect of meals on nutritional status, but patients reported positive attitudes toward receiving meals during dialysis.ConclusionHigh-protein meals during HD did not increase symptomatic hypotension events. Larger, longer term studies are needed to confirm these results and evaluate whether high-protein meals on dialysis benefit nutritional status and clinical outcomes.

Project description:BackgroundIntradialytic hypertension occurs in 5-20% of hemodialysis treatments. Observational data support an association between intradialytic hypertension and long-term mortality. However, the short-term consequences of recurrent intradialytic hypertension are unknown.MethodsData were taken from a cohort of prevalent hemodialysis patients receiving treatment at a large United States dialysis organization on 1 January 2010. A retrospective cohort design with a 180-day baseline, 30-day exposure assessment, and 30-day follow-up period was used to estimate the associations between intradialytic hypertension frequency and 30-day outcomes. Intradialytic hypertension frequency was defined as the proportion of exposure period hemodialysis treatments with a predialysis to postdialysis systolic blood pressure rise >0 mm Hg. Multivariable Cox proportional hazards regression, adjusted for baseline clinical, laboratory, and dialysis treatment covariates, was used to estimate hazard ratios and 95% confidence intervals.ResultsOf the 37,094 study patients, 5,242 (14.1%), 17,965 (48.4%), 10,821 (29.2%), 3,066 (8.3%) had intradialytic hypertension in 0%, 1-32%, 33-66%, and ≥67% of exposure period treatments, respectively. More frequent intradialytic hypertension was associated with incremental increases in 30-day mortality and hospitalizations. Patients with intradialytic hypertension in ≥67% (vs. 0%) of exposure period treatments had the highest risk of all-cause death, hazard ratio [95% confidence interval]: 2.57 [1.68, 3.94]; cardiovascular (CV) death, 3.68 [1.89, 7.15]; all-cause hospitalizations, 1.42 [1.26, 1.62]; CV hospitalizations, 1.71 [1.36, 2.15]; and volume-related hospitalizations, 2.25 [1.25, 4.04].ConclusionsAmong prevalent hemodialysis patients, more frequent intradialytic hypertension was incrementally associated with increased 30-day morbidity and mortality. Intradialytic hypertension may be an important short-term risk marker in the hemodialysis population.

Project description:BackgroundThere is increasing awareness that, besides patient survival, Quality of Life (QOL) is a relevant outcome factor for patients who have a chronic disease. In haemodialysis (HD) patients, intradialytic hypotension (IDH) is considered one of the most frequent complications, and this is often accompanied by symptoms. Several studies have investigated QOL in dialysis patients, however, research on the association between intradialytic symptoms and QOL is minimal. The goal of this study was to determine whether the occurrence of IDH has an influence on the perception of QOL.MethodsDuring 3 months, haemodynamic data, clinical events, and interventions of 2623 HD-sessions from 82 patients were prospectively collected. The patients filled out a patient-reported intradialytic symptom score (PRISS) after each HD session. IDH was defined according to the EBPG as a decrease in SBP ≥20 mmHg or in MAP ≥10 mmHg associated with a clinical event and need for nursing interventions. Patient's self-assessment of QOL was evaluated by the 36-Item Short-Form Health Survey.ResultsThere were no significant associations between the mental summary score or the physical summary score and the proportion of dialysis sessions that fulfilled the full EBPG definition. A lower PRISS was significantly associated with the proportion of dialysis sessions that fulfilled the full EBPG definition (R = - 0.35, P = 0.0011), the proportion of dialysis sessions with a clinical event (R = - 0.64, P = 0.001), and the proportion of dialysis sessions with nursing interventions (R = - 0.41, P = 0.0001). The physical component summary and mental component summary were significantly negatively associated with the variable diabetes and positively with PRISS (P = 0.003 and P = 0.005, respectively). UF volume was significantly negatively associated with mental health (P = 0.02) and general health (P = 0.01).ConclusionsOur findings suggest that the EBPG definition of IDH does not capture aspects of intradialytic symptomatology that are relevant for the patient's QOL. In contrast, we found a significant association between QOL and a simple patient-reported intra-dialytic symptom score, implying that how patients experience HD treatment influences their QOL.
