简要总结
The objective of this study is to determine the effect on quality of care when introducing smart technology in patients who underwent cardiovascular surgery. Patients who consent to take part in the study, receive a box containing two smartphone compatible ECG monitors, an oxygen saturation monitor, a weight scale, a thermometer, an activity tracker and a blood pressure monitor. They will be followed up by replacing one of the outpatient clinic visits by an e-consult, in which a patients does not have to go to the hospital. Instead, he or she will talk with his or her doctor or nurse practitioner via a secured video connection. The primary endpoint of the study will be the diagnosis of atrial fibrillation within 3 months after cardiac surgery.
详细描述
Over the past five years, smartphone compatible detectors of cardiovascular disease parameters have been released on the consumers market. Examples of these include heart rate monitors, ECG monitors, blood pressure monitors, activity trackers and fat percentages monitors. These monitors have often been validated and are CE-marked for use in the European Union within their intended use.
Recent publications implicate that home monitoring with such consumer devices might improve quality of care. A study by Bosworth et al. in patients with hypertension showed that increased monitoring and subsequent treatment led to a better controlled blood pressure in patients who were treated for hypertension. Another study, which is currently being carried out at the LUMC, is investigating whether patients benefit from a smart technology intervention after they had a myocardial infarction. Preliminary (unpublished) results show that clinical outcomes are similar, with higher patient satisfaction. Cost analyses show that there is a cost reduction per patient with smart technology follow-up. Therefore, smart technology could be a useful tool to improve patient monitoring and therefore patient safety.
Patients who are discharged after they underwent cardiovascular surgery are at risk to develop one or more of three most seen late complications: sternal wound infection, cardiac decompensation or rhythm disturbances such as atrial fibrillation. This is not always detected before those patients are discharged.
Currently, patients who underwent cardiovascular surgery return to the outpatient clinic 14 days and three months after discharge. They are seen by a specialist nurse or cardiologist, who will perform a general check-up and inspect the sternal wound. An echocardiogram will be performed before the three-month visit. If there is suspicion for a rhythm disturbance on the outpatient clinic visit, the cardiologist might decide to perform Holter monitoring during 24 hours. As this is a small window of time, not all rhythm disturbances will be diagnosed. Smart technology is hypothesized to increase the chances of diagnosing rhythm disturbances. In the case of sternal wound infection and cardiac decompensation, smart technology may show a declining trend before a patient visits the outpatient clinic, which can lead to early detection and treatment.
A small pilot study by McElroy et all found that after cardiovascular surgery, both the patient as well as the health care team are highly satisfied with added smart technology, due to the ease of use of the technology and platform. There was a main focus on readmission rates, which did not differ between the groups. However the trend shows an increase in diagnosing atrial fibrillation (15,4 vs 29,6%), sternal wound infection or cardiac decompensation were not studied.
