[Application and Effect of Patient Portal System in the Remote Management of Chronic Diseases for Older Adults With Coronary Heart Disease].

OBJECTIVE

To investigate the application of personal health record (PHR) and chronic disease management platform established on the basis of patient portal system (PPS) in managing older adults with coronary heart disease and to examine the effect on patients' self-care ability, coping mode, and quality of life.

METHODS

A total of 532 elderly patients with coronary heart disease were included in the study. All the participants enrolled were admitted to a tertiary-care hospital between January 2019 and June 2021. They were randomly assigned to the study group (269 cases) and the control group (263 cases). Patients in the control group were discharged with the routine discharge procedures and received the routine follow-up care. On the other hand, patients in the study group were discharged and followed up through the PHR and chronic disease management platform established on the basis of PPS. After 6 months, 12 months, and 18 months of patient management, the Exercise of Self-Care Agency (ESCA) Scale, Medical Coping Modes Questionnaire (MCMQ) and Seattle Angina Questionnaire (SAQ) were used to evaluate the patients' self-care ability, coping mode, and quality of life, respectively. The patient management effects of the two groups were analyzed.

RESULTS

Before the management programs started, there was no statistically significant difference in the scores for the scales between the two groups of patients. After 6 months, 12 months, and 18 months of patient management, the ESCA scores of both groups were higher than those before patient management started (<0.05). Facing scores in the MCMQ of both groups were higher than those before patient management started (<0.05), while the scores for avoidance and yielding were lower than those before patient management started (<0.05). The SAQ scores of both groups were higher than those before patient management started (<0.05). After 6 months, 12 months and 18 months of patient management, the ESCA scores of the study group were always higher compared with those of the control group (<0.05). The facing score of the study group was higher, while the scores for avoidance and yielding were lower compared with those of the control group (<0.05). The SAQ scores of the study group were higher compared with those of the control group (<0.05). The medication compliance rate in the study group (83.27%) was higher than that in the control group (69.96%) (<0.05). The incidence of adverse cardiovascular events in the study group (4.09%) was lower than that in the control group (10.27%) (<0.05). The average times of emergency treatment and readmission in the study group were lower compared with those of the control group (<0.05). The patient satisfaction score of the study group was higher compared with that of the control group (<0.05).

CONCLUSION

The PHR and chronic disease management platform established on the basis of PPS can increase the convenient access to medical care among elderly patients with coronary heart disease, which is conducive to improving their self-care ability, coping mode, and quality of life. In addition, the patient management effect is good.
