Telemedicine and decentralized models of care: from anticoagulant monitoring to an expanded concept of vascular medicine

Socioeconomic Burden of Pulmonary Embolism in Europe: Shifting Priorities and Challenges for Novel Reperfusion Strategies

In-hospital case fatality related to acute pulmonary embolism (PE) has been falling since the beginning of this century. However, annual incidence rates continue to climb, and an increasing number of PE survivors need long-term follow-up, chronic anticoagulation treatment, and readmission(s) to the hospital. In European countries, median reimbursed hospital costs for acute PE are still moderate compared with the United States but can increase several-fold in patients with comorbidities and those necessitating potentially life-saving reperfusion treatment. The use of catheter-directed treatment (CDT) has constantly increased in the United States since the past decade, and it has now entered a rapid growth phase in Europe as well, estimated to reach an annual penetration rate of up to 31% among patients with intermediate-high- or high-risk PE by 2030. Ongoing randomised controlled trials are currently investigating the clinical efficacy and safety of these devices. In addition, they will deliver data permitting calculation of their cost-effectiveness in different health care reimbursement systems, by revealing the extent to which they can reduce complications and consequently the need for intensive care and the overall length of hospital stay. After discharge, key cost drivers are related to chronic cardiopulmonary diseases (other than PE itself) leading to frequent readmissions, persistent symptoms, and functional limitations which result in poor quality of life, productivity loss, and substantial indirect costs. Implementation of structured outpatient programmes with a holistic approach to post-PE care, targeting overall cardiovascular health and the patient's well-being, bears the potential to cost-effectively reduce the overall socioeconomic burden of PE.

The benefits of a centralized remote surveillance program for vascular patients

OBJECTIVE

We aimed to assess the clinical and financial utility of a centralized remote surveillance program for vascular patients compared with traditional outpatient follow-up.

METHODS

In 2014, the Royal Adelaide Hospital Department of Vascular Surgery introduced a centralized remote surveillance program where suitable patients were monitored by remote imaging in lieu of traditional outpatient appointments (OPAs). Surveillance imaging was performed at a site local to the patient and was reviewed centrally by a dedicated surveillance nurse. We undertook a 5-year retrospective analysis of the program's prospectively maintained database since its inception. Costs for inpatient admissions and OPAs were retrieved from hospital financial databases. The surveillance database and electronic patient records were analyzed for number and outcome of surveillance scans, interventions, and OPAs. Additional savings in travel distance, fuel costs, and CO₂ emissions were also calculated.

RESULTS

Over 5 years, 1262 patients underwent a mean of four scans per patient. A total of 3718 OPAs were saved, approximating 930 hours of clinic and consultant time, with associated savings of Australian (A)$1,524,900 (United States [US]$ 1,065,684) over 5 years (A$ 304,980 [US$ 213,137] per year). For every OPA avoided, each patient saved 197 km travel and A$87 (US$ 61) fuel costs, with an associated 115 kg of CO₂ emissions saved. Over 5 years, this equated to savings of 248,173 km travel, A$ 110,136 (US$ 76,969) fuel costs, and 146 tons of CO₂ emissions. A total of 134 surveillance-detected pathologies (10.6%) required intervention, a further 28 despite surveillance (2.2%), and three following surveillance cessation (0.2%). Subgroup analysis demonstrated that interventions despite surveillance were three times more expensive and incurred four times longer admissions than those due to surveillance.

CONCLUSIONS

Remote vascular surveillance, particularly applicable in our current COVID-19 pandemic climate, is associated with quantifiable financial, clinical, patient, and environmental beneficial outcomes and can be safely delivered to populations spanning large geographical areas such as those in Australia.

Role of telemedicine in the management of oral anticoagulation in atrial fibrillation: a practical clinical approach

Compared with face-to-face consultations, telemedicine has many advantages, including more efficient use of healthcare resources, partial relief of the burden of care, reduced exposure to COVID-19, treatment adjustment, organization of more efficient healthcare circuits and patient empowerment. Ensuring optimal anticoagulation in atrial fibrillation patients is mandatory if we want to reduce the thromboembolic risk. Of note, telemedicine is an excellent option for the long-term management of atrial fibrillation patients. Moreover, direct oral anticoagulants may provide an added value in telemedicine (versus vitamin K antagonists), as it is not necessary to monitor anticoagulant effect or make continuous dosage adjustments. In this multidisciplinary consensus document, the role of telemedicine in anticoagulation of this population is discussed and practical recommendations are provided.

Digital literacy as a potential barrier to implementation of cardiology tele-visits after COVID-19 pandemic: the INFO-COVID survey

BACKGROUND

During the COVID-19 pandemic, the implementation of telemedicine has represented a new potential option for outpatient care. The aim of our study was to evaluate digital literacy among cardiology outpatients.

METHODS

From March to June 2020, a survey on telehealth among cardiology outpatients was performed. Digital literacy was investigated through six main domains: age; sex; educational level; internet access; availability of internet sources; knowledge and use of teleconference software programs.

RESULTS

The study included 1067 patients, median age 70 years, 41.3% females. The majority of the patients (58.0%) had a secondary school degree, but among patients aged ≥ 75 years old the most represented educational level was primary school or none. Overall, for internet access, there was a splitting between "never" (42.1%) and "every day" (41.0%), while only 2.7% answered "at least 1/month" and 14.2% "at least 1/week". In the total population, the most used devices for internet access were smartphones (59.0%), and WhatsApp represented the most used app (57.3%). Internet users were younger compared to non-internet users (63 vs. 78 years old, respectively) and with a higher educational level. Age and educational level were associated with non-use of internet (age-per 10-year increase odds ratio (OR) = 3.07, 95% CI: 2.54-3.71, secondary school OR = 0.18, 95% CI: 0.12-0.26, university OR = 0.05, 95% CI: 0.02-0.10).

CONCLUSIONS

Telemedicine represents an appealing option to implement medical practice, and for its development it is important to address the gaps in patients' digital skills, with age and educational level being key factors in this setting.
