Costs and Cardiovascular Benefits of a Fourth-Generation Synchronous Telehealth Program on Mortality and Cardiovascular Outcomes for Patients With Atrial Fibrillation: Retrospective Cohort Study.

BACKGROUND: The prevalence of atrial fibrillation (AF) continues to increase in modern aging society. Patients with AF are at high risk for multiple adverse cardiovascular events, including heart failure, stroke, and mortality. Improved medical care is needed for patients with AF to enhance their quality of life and limit their medical resource utilization. With advances in the internet and technology, telehealth programs are now widely used in medical care. A fourth-generation telehealth program offers synchronous and continuous medical attention in response to physiological parameters measured at home. Although we have previously shown the benefits of this telehealth program for some patients with a high risk of cardiovascular disease, its benefits for patients with AF remains uncertain. OBJECTIVE: This study aims to investigate the benefits of participating in a fourth-generation telehealth program for patients with AF in relation to cardiovascular outcomes. METHODS: This was a retrospective cohort study. We retrospectively searched the medical records database of a tertiary medical center in Northern Taiwan between January 2007 and December 2017. We screened 5062 patients with cardiovascular disease and enrolled 537 patients with AF, of which 279 participated in the telehealth program and 258 did not. Bias was reduced using the inverse probability of treatment weighting adjustment based on the propensity score. Outcomes were collected and analyzed, including all-cause readmission, admission for heart failure, acute coronary syndrome, ischemic stroke, systemic embolism, bleeding events, all-cause mortality, and cardiovascular death within the follow-up period. Total medical expenses and medical costs in different departments were also compared. Subgroup analyses were conducted on ischemic stroke stratified by several subgroup variables. RESULTS: The mean follow-up period was 3.0 (SD 1.7) years for the telehealth group and 3.4 (SD 1.9) years for the control group. After inverse probability of treatment weighting adjustment, the patients in the telehealth program had significantly fewer ischemic strokes (2.0 vs 4.5 events per 100 person-years; subdistribution hazard ratio [SHR] 0.45, 95% CI 0.22-0.92) and cardiovascular deaths (2.5 vs 5.9 events per 100 person-years; SHR 0.43, 95% CI 0.18-0.99) at the follow-up. The telehealth program particularly benefited patients comorbid with vascular disease (SHR 0.11, 95% CI 0.02-0.53 vs SHR 1.16, 95% CI 0.44-3.09; P=.01 for interaction). The total medical expenses during follow-up were similar in the telehealth and control groups. CONCLUSIONS: This study demonstrated the benefits of participating in the fourth-generation telehealth program for patients with AF by significantly reducing their ischemic stroke risk while spending the same amount on medical expenses.

[Increasing the Accuracy of Extracorporeal Membrane Oxygenation Critical Event Management in the Medical Intensive Care Unit].

BACKGROUND & PROBLEMS: Extracorporeal membrane oxygenation (ECMO) is an intervention that replaces cardiopulmonary function temporarily to reduce injury to vital organs. As important members of the ECMO medical team, intensive care unit nurses must be well trained and alert to possible critical events. Failure to troubleshoot and manage ECMO promptly and correctly significantly increases the risk of mortality. A previous ECMO critical event in our unit resulted in lingering concerns and stress among nurses related to implementing this intervention. A survey conducted among our medical intensive care unit (MICU) nurses identified an implementation accuracy level for ECMO critical event management of only 59.1%. This poor result was attributed to a lack of technical assessment standards, in-service training, clinical experience, and instruction materials and the failure to offer online courses. PURPOSE: This study was designed to increase the accuracy of ECMO critical event management implementation among intensive care unit nurses to >86%. RESOLUTIONS: We conducted a problem-based training project to improve ECMO critical event management that: introduced a technical assessment sheet and technical simulation exercise, organized in-service training, implemented irregular simulation exercises, and produced multiple different instructional materials. RESULTS: The accuracy of ECMO critical event management implementation among the intensive care unit nurses increased from 59.1% pretest to 95.9% posttest. CONCLUSIONS: This project improved the ECMO care ability of MICU nurses in our hospital significantly, resulting in increased ECMO critical event management implementation accuracy, better patient care, higher nursing staff confidence, and lower perceived stress among nursing staff.

[Improvement of Medical Alarm Management Accuracy for Critical Care Nurses in a Continuous Renal Replacement Therapy Unit].

BACKGROUND: Continuous renal replacement therapy (CRRT) is a common medical treatment for critically ill patients. The alarm management component of CRRT is urgent and time sensitive. Patient safety and survival rates are jeopardized if critical care nurses do not handle this situation properly. However, clinical settings cannot provide nurses with the opportunity to practice alarm management, which results in related training difficulties. Based on a survey conducted in May 2018, the rate of proper alarm management for the nurses in our CRRT unit was only 53.1%. An investigation attributed this low rate to inadequacies in standard procedures, resources for reference, opportunities for hands-on experience, professional training at different levels, immediate assistance from industry, and lack of familiarity with the purpose and handling of alarm incidents. These findings motivated our project team to improve alarm management. PURPOSE: To increase the accuracy of alarm management in CRRT critical care nurses to more than 90%. RESOLUTIONS: This project, which was implemented from September 8th, 2018 to August 31st, 2019, adopted a diverse and effective teaching strategy that included establishing standard procedures and technical tests; creating a plan for a case scenario simulation course using flipped teaching; providing scenario simulation videos; and designing online scenario simulation interactive exercises, nursing manuals, and flashcards of simplified procedures. RESULTS: The accuracy rate of proper alarm management for CCRT critical care nurses increased from 53.1% to 98.9%. CONCLUSIONS: Diverse teaching strategies may be used to effectively enhance the care provided by critical care nurses, increase patient safety, and improve the quality of care. The findings and strategies in this study may also be applied to other intensive care units.
