To evaluate the effect applying intelligent nursing information system in the continuous intervention for patients with acute chronic heart failure after discharge.

This was a retrospective study. A total of 100 patients with acute chronic heart failure admitted to Intensive Care Unit (ICU), Houjie Hospital from January to December 2020 were selected. From January to June 2020, 50 patients with acute attack of chronic heart failure in ICU who received routine care under the intelligent nursing information system were selected as a control group. From July 2020 to December 2020, the rest 50 patients with acute attack of chronic heart failure in ICU were selected as an experimental group. The control group had 28 males and 22 females; they were (60.6±4.7) years old; the disease duration was (5.1±0.6) years; and the hospitalization duration was (20.2±2.7) days. The experimental group had 27 males and 23 females; they were (60.5±4.8) years old; the disease duration was (5.2±0.5) years; the hospitalization duration was (20.1±2.6) days. The scores of Exercise of Self-Care Agency (ESCA) and quality of life, readmission rates, and incidences of adverse reactions were observed and analyzed in the 2 groups. t test and χ² test were used for the comparison between the groups.

Before the intervention, the scores of ESCA and quality of life were (99.1±13.5) and (66.1±7.4)) in the control group, and were (98.6±13.8) and (65.8±7.1) in the experimental group, with no statistical differences (both P>0.05). After the intervention, the scores of ESCA and quality of life were (101.1±10.5) and (74.2±8.1) in the control group, and were (108.9±11.4) and (82.1±9.4) in the experimental group, with statistical differences (t=3.559 and 4.502; both P<0.001). Within one year after discharge, the readmission rate and incidence of adverse reactions were 4.0% (2/50) and 2.0% (1/50) in the experimental group, and were 18.0% (9/50) and 22.0% (11/50) in the control group, with statistical differences (χ²=5.005 and 9.470; P=0.025 and 0.002).

The implementation of continuous intervention under intelligent nursing information system can improve the self-care ability of ICU patients with acute attack of chronic heart failure, reduce the occurrence of adverse reactions and readmission rate, and improve their quality of life.
