A comparative study of fluid management education before hospital discharge

Formulation and application of the "hospital-to-home + online-to-offline" treatment scheme in caring for and supporting vulnerable patients with chronic heart failure

BACKGROUND

Chronic heart failure (CHF) is the terminal stage of cardiovascular disease.

OBJECTIVE

In this study, the "hospital-to-home + online-to-offline" (H2H + O2O) care scheme was implemented for patients with CHF during vulnerable periods, and its effect was evaluated.

METHODS

Patients with CHF in the cardiovascular department of a Class III/Grade A hospital in Jiangxi Province from January to December 2020 were selected using a convenience sampling method and randomly divided into a control and intervention group (n= 100 each). The patients in the control group received routine in-hospital treatment and out-of-hospital follow-up, while in the intervention group, a multi-disciplinary cooperation team with CHF specialist nurses evaluated and stratified the patients before discharge and formulated individualized prescriptions and care plans. Based on the "Health & Happiness" chronic disease follow-up application designed for this study, the specialist nurses provided patients with one-to-one guidance. After three months, the cardiac function, heart failure knowledge, self-care behavior, and re-hospitalization rate of the patients were compared between the two groups. Cardiac function was evaluated by the serum B-type natriuretic peptide (BNP), the left ventricular ejection fraction (LVEF), and a six-minute walking test (6MWT). Heart failure knowledge and self-care behavior was assessed using specific questionaries.

RESULTS

The level of cardiac function in the intervention group was significantly higher than that in the control group, and the difference was statistically significant (P< 0.001). The mastery of heart failure knowledge and self-care behavior in the intervention group were significantly higher than those in the control group, and the differences were statistically significant (P< 0.05). The re-hospitalization rate due to CHF in the intervention group was 21.0%, which was lower than that in the control group (35.0%), and the difference was statistically significant (P< 0.05).

CONCLUSION

The H2H + O2O care scheme can be used for the transition of vulnerable patients with CHF from the hospital to family care to improve the patients' level of cardiac function, elevate their knowledge level and self-care abilities, and improve their overall health outcomes.

Use of novel non-invasive techniques and biomarkers to guide outpatient management of fluid overload and reduce hospital readmission: systematic review and meta-analysis

Aims

Fluid congestion is a leading cause of hospital admission, readmission, and mortality in heart failure (HF). We performed a systematic review and meta‐analysis to determine the effectiveness of an advanced fluid management programme (AFMP). The AFMP was defined as an intervention providing tailored diuretic therapy guided by intravascular volume assessment, in hospitalized patients or after discharge. The AFMP group was compared with patients who received standard care treatment. The aim of this systematic review and meta‐analysis was to determine the effectiveness of an AFMP in improving patient outcomes.

Methods and results

A systematic review of randomized controlled trials, case–control studies, and crossover studies using the terms ‘heart failure’, ‘fluid management’, and ‘readmission’ was conducted in PubMed, CINAHL, and Scopus up until November 2020. Studies reporting the association of an AFMP on readmission and/or mortality were included in our meta‐analyses. Risk of bias was assessed in non‐randomized studies using the Newcastle–Ottawa Scale. From 232 retrieved studies, 12 were included in the data synthesis. The 6040 patients in the included studies had a mean age of 72 ± 4 years and mean left ventricular ejection fraction of 39 ± 8%, there were slightly more men (n = 3022) than women, and the follow‐up period was a mean of 4.8 ± 3.1 months. Readmission data were available in 5362 patients; of these, 1629 were readmitted. Mortality data were available in 5787 patients; of these, 584 died. HF patients who had an AFMP in hospital and/or after discharge had lower odds of all‐cause readmission (odds ratio—OR 0.64 [95% confidence interval—CI 0.44, 0.92], P = 0.02) with moderate heterogeneity (I² = 46.5) and lower odds of all‐cause mortality (OR 0.82 [95% CI 0.69, 0.98], P = 0.03) with low heterogeneity (I² = 0). The use of an AFMP was equally effective in reducing readmission and mortality regardless of age and follow‐up duration. Effective pre‐discharge diuresis was associated with significantly lower readmission odds (OR 0.43 [95% CI 0.26, 0.71], P = 0.001) compared with a fluid management plan as part of post‐discharge follow‐up.

Conclusions

An effective AFMP is associated with improving readmission and mortality in HF. Our results encourage attainment of optimal volume status at discharge and prescription of optimal diuretic dose. Ongoing support to maintain euvolaemia and effective collaboration between healthcare teams, along with effective patient education and engagement, may help to reduce adverse outcomes in HF patients.

Patterns of adherence to diuretics, dietary sodium and fluid intake recommendations in adults with heart failure

BACKGROUND

Three behaviors advocated to minimize fluid-related hospitalizations in patients with heart failure (HF) are restricted sodium and fluid intake and consistent oral diuretic use. Adherence to behaviors intended to decrease risk of hospitalization is believed to vary over time, but surprisingly little research has addressed patterns of adherence in HF patients.

OBJECTIVE

To describe patterns over time of 3 recommended self-care behaviors (i.e., diet, fluid intake, and diuretic dosing) in adults with HF and to determine how time and behavior influenced adherence rates.

METHODS

We enrolled 24 adults hospitalized for a HF exacerbation and discharged on a loop diuretic into a descriptive, longitudinal pilot study. Over 3-months, diuretic use was measured using electronic event monitoring, and participants were telephoned regularly to assess sodium and fluid intake. Data were summarized for each 2-week intervals.

RESULTS

The overall adherence rates were 42.4% for low sodium diet, 96.4% for fluid restriction, and 84.7% for the diuretic regimen. Early after hospital discharge, medication adherence was the highest, and dietary adherence was the lowest, but adherence to diet and diuretic use decreased significantly over time.

CONCLUSION

Although participants were just discharged from the hospital after an acute exacerbation of HF, all three behavioral patterns decreased markedly over the 3-month follow-up period.

Fluid restriction in patients with heart failure: how should we think?

BACKGROUND/AIM

Fluid restriction has long been considered one of the cornerstones in self-care management of patients with heart failure. The aim of this discussion paper is to discuss fluid restriction in heart failure and propose advice about fluid intake in heart failure patients.

RESULTS

Although there have been seven randomised studies on fluid restriction in heart failure patients, the effect of fluid restriction on its own were only evaluated in two studies. In both studies, a stringent fluid restriction compared to a liberal fluid intake was not more beneficial with regard to clinical stability or body weight. In the other studies fluid restriction was part of a larger study intervention including, for example, individualised dietary recommendations and follow-up by telephone. Thus, the effect of fluid restriction on its own has been poorly evaluated.

CONCLUSION

Fluid restriction should not be recommended to all heart failure patients. However, temporary fluid restriction can be considered in decompensated heart failure and/or patients with hyponatremia. Tailored fluid restriction based on body weight (30 ml/kg per day) seems to be most reasonable. To increase adherence to temporary fluid restriction, education, support and planned evaluations can be recommended.
