ObjectiveTo explore the application and effectiveness of a home monitoring system-based remote follow-up platform in patients after pacemaker implantation.Methods A convenience sampling method was employed to select patients who received implantation of dual-chamber pacemakers with home monitoring functions as participants. Forty-two patients admitted between January 2021 and March 2022 were included in the control group, and 41 patients admitted between April 2022 and June 2023 were included in the experimental group. The control group received routine outpatient follow-up, while the experimental group received follow-up management through a home monitoring system-based remote follow-up platform. After 6 months of intervention, shoulder joint function, self-care ability, outpatient follow-up frequency, and the effectiveness of the follow-up intervention were compared between the two groups. Results There were patients in each group who completed the entire study. After 6 months of intervention, the experimental group had significantly fewer outpatient follow-ups than the control group;the total score of shoulder joint function, as well as the scores in the three dimensions of daily living ability, shoulder joint mobility, and shoulder joint pain, were significantly higher in the experimental group than in the control group; additionally, the total score of self-care ability was significantly higher in the experimental group than in the control group (all P<0.05). The overall effectiveness rate of the intervention in the experimental group was 93.5%. Conclusion The home monitoring system-based remote follow-up platform provides professional support for patients during home care, improves shoulder joint function and self-care ability after pacemaker implantation, reduces outpatient follow-up frequency, and enhances the effectiveness of follow-up interventions.
