Role of Monitoring Devices in Preventing Heart Failure Admissions

Evolution of self-care in patients with heart failure at the first outpatient return and three months after hospital discharge

OBJECTIVE

to analyze the evolution of self-care in hospitalized patients with decompensated heart failure, between the first return after hospital discharge (T0) and three months after this assessment (T1).

METHOD

an observational, analytical and longitudinal study carried out in the cardiology outpatient clinics of two public hospitals in Ribeirão Preto, São Paulo. The sociodemographic and clinical data were collected through interviews and consultation of medical records. Self-care was assessed using the Brazilian version of the Self-Care of Heart Failure Index-SCHFI instrument. The data were analyzed by means of the Student's t test and paired distribution (McNemar) with a significance level of 0.05.

RESULTS

we verified an increase in the mean scores of the three subscales of SCHFI (Maintenance, Management and Confidence), when comparing the values of T0 and T1, these differences being statistically significant (p<0.001). When comparing the positive changes in self-care actions over these months, we found statistically significant changes in the Maintenance (6 out of 10 items), Management (5 out of 6 items) and Confidence (4 out of 6 items) subscales.

CONCLUSION

self-care for heart failure improved in the period between the first return after discharge and the end of three months of follow-up. Further studies are needed to verify the variables associated with improved self-care after hospitalization.

Impact of an Outpatient Cardiology-managed Urgent Access and Observation Unit on Hospital Admissions

INTRODUCTION

Alternatives to the emergency department (ED) for expedient and high-value team-based cardiology care for patients with chest pain, volume overload, palpitations, and other urgent, but not life-threatening cardiac conditions are lacking. Here, we report on the development of the Cardiac Direct Access Unit (CDAc), an ambulatory cardiology unit with exam rooms, observation bays, and an advanced heart failure clinic.

METHODS

Patients referred to the CDAc are seen same-day by an attending cardiologist in a space independent from the ED. We performed a retrospective review of 1146 consecutive patients referred to the CDAc in its first year of operation. Among patients who were referred for urgent same-day evaluation, 60.1% were discharged home without observation.

RESULTS

Among the patients observed or directly discharged from CDAc, 2.4% were readmitted within 30 days for a related symptom. The highest rate of readmission (7.5%) was for heart failure, which compares favorably with guidelines for readmission benchmarks.

CONCLUSION

Our first year of data suggests that a cardiology-directed observation unit may serve as a high-value alternative to the ED for appropriately selected patients.

Physical Activity and Sleep Analysis of Heart Failure Patients using Multi-sensor Patches

Traditional heart failure markers fail to reliably predict heart-failure related hospitalisations and deaths. Multi- sensor patch data can provide an objective insight into activity and sleep patterns of patients and may therefore improve the performance of current risk-quantification algorithms. This work aimed to establish the feasibility of collecting multi-sensor patch data from heart failure patients and to perform an initial analysis of activity and sleep patterns of heart failure patients in relation to disease severity. 13 heart failure patients from the SUPPORT-HF study were provided with chest-worn multisensor patches and asked to wear the devices continuously for up to seven consecutive days. Using a combination of impedance, heart rate and accelerometer data participants' sleep and wakefulness information were extracted and analyzed in relation to self-reported symptom scores. Patch data for eleven patients were of high enough quality to be included in the analysis, accounting for 63 patient days worth of data. The heart failure patients slept for an average of 8.3 hours a night and experienced 2.8 sleep interruptions. Potential differences in sleep angle, heart rate and wake-time activity were found for patients with different heart failure severity. Larger studies are necessary to create a more coherent picture of the potential of activity and sleep as a markers for heart failure deterioration.
