Purpose
Multiple chronic illnesses, such as those associated with advanced age, are leading causes of poor health, disability, death, and high healthcare expenditures. Tele‐homecare is a novel method for providing home care to patients with chronic illnesses. The purpose of this study was to evaluate the effectiveness of an integrated nurse‐led tele‐homecare program for patients with multiple chronic illnesses and a high risk for readmission.
Design
A randomized controlled trial.
Methods
Two hundred patients from a regional hospital who were scheduled to receive home care after discharge were randomly assigned to the intervention group (n = 100) or the control group (n = 100). The patients in the intervention group participated in an integrated tele‐homecare program. For outcome evaluation, primary outcomes included the number of emergency department (ED) visits as well as readmittance and mortality. Secondary outcomes included patients’ medication adherence, activities of daily living, health status, and quality of life (QOL). Data were collected at three time points: pretest baseline (T0), 3 months after intervention (T3), and 6 months after intervention (T6). A generalized estimating equation model was used to compare changes and evaluate the effect of differences between the two groups over time.
Findings
For primary outcome evaluation, we found that the tele‐homecare program significantly reduced mortality and ED visits, whereas no significant effect on readmission was observed. For secondary outcome evaluation, patients’ QOL indicated significant improvement.
Conclusions and Clinical Relevance
The nurse‐led tele‐homecare program involves daily 24‐hr remote monitoring and surveillance. In this study, the system detected patients’ physical changes early and provided timely and appropriate management, consequently reducing ED visits and mortality. Additionally, it improved patients’ QOL. On the basis of our findings, nurses’ independent roles and functions revealed that the effectiveness of this nurse‐led tele‐homecare program strengthened the care of patients with multiple chronic illnesses.
To understand the mechanism for inhibition of hepatitis B virus (HBV) infection is important. In this study, single-chain variable fragment (scFv) antibodies were generated and directed to the pre-S2 epitope of HBV surface antigen (HBsAg). These human scFvs were isolated from a person with history of HBV infection by phage display technology. An evaluation of panning efficiency revealed that the eluted phage titer was increased, indicating that specific clones were enriched after panning. Selected scFvs were characterized with the recombinant HBsAg through Western blotting and enzyme-linked immunosorbent assay to confirm the binding ability. Flow cytometry analysis and immunocytochemical staining revealed that one scFv, S17, could recognize endogenous HBsAg expressed on the HepG2215 cell membrane. Moreover, the binding affinity of scFv S17 to the pre-S2 epitope was determined to be 4.2 × 10 M. Two ion interactions were observed as the major driving forces for scFv S17 interacting with pre-S2 by performing a rational molecular docking analysis. This study provides insights into the structural basis to understand the interactions between an antibody and the pre-S2 epitope. The functional scFv format can potentially be used in future immunotherapeutic applications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
