Efficiency of telemedicine for acute stroke: a cost-effectiveness analysis from a French pilot study

Telestroke for acute ischaemic stroke: A systematic review of economic evaluations and a de novo cost-utility analysis for a middle income country

INTRODUCTION

Telemedicine can alleviate the problems faced in rural settings in providing access to specialist stroke care. The evidence of the cost-effectiveness of this model of care outside high-income countries is limited. This study aimed to conduct: (a) a systematic review of economic evaluations of telestroke and (b) a cost-utility analysis of telestroke, using China as a case study.

METHODS

We systematically searched Embase, Medline Complete and Cochrane databases. Inclusion criteria: full economic evaluations of telemedicine/telestroke networks examining the use of thrombolysis in patients with acute ischaemic stroke, published in English. A cost-utility analysis was undertaken using a Markov model incorporating a decision tree to simulate the delivery of telestroke for acute ischaemic stroke in rural China, compared to no telestroke from a societal and healthcare perspective. One-way deterministic sensitivity analyses and probabilistic sensitivity analyses were performed to test the robustness of results.

RESULTS

Of 559 publications found, eight met the eligibility criteria and were included in the systematic review (two cost-effectiveness analyses and six cost-utility analyses, all performed in high-income countries). Telestroke was a cost-saving/cost-effective intervention in five out of the eight studies. In our modelled analysis for rural China, telestroke was the dominant strategy, with estimated cost savings of Chinese yuan 4,328 (US$627) and additional 0.0925 quality-adjusted life years per patient. Sensitivity analyses confirmed the base case results.

DISCUSSION

Consistent with published economic evaluations of telestroke in other jurisdictions, telestroke represents a cost-effective solution to enhance stroke care in rural China.

Ambulatory Virtual Care During a Pandemic: Patient Safety Considerations

BACKGROUND

The COVID-19 pandemic prompted sudden and fundamental changes in health care, including a rapid rise in the utilization of telehealth services in the ambulatory setting. With the unprecedented and significant decline in traditional office-based visits and procedures, novel patient safety risks and challenges emerged.

METHODS

The ambulatory practices at our quaternary care, academic medical center experienced a 200-fold increase in virtual visit volume between February and April 2020. We convened a multidisciplinary working group dedicated to evaluating quality and safety when providing virtual visits during a pandemic. Our primary outcome was patient experience with virtual care delivery, which was assessed by leveraging patient complaint data and patient satisfaction survey data.

RESULTS

For our main focus of patient experience and satisfaction, survey data were analyzed from the approximately 76,616 virtual visit encounters that occurred between March 1, 2020, and April 21, 2020. During this period, 5 patient complaints were filed to the Patient Advocacy Department. Overall, patient satisfaction with telehealth remained stable and high at >93% from February to May 2020. As we assessed these data each month, our working group developed risk mitigation strategies in response to the novel challenges presented by the use of telemedicine due to the COVID-19 pandemic while working to maintain patient satisfaction with care. We identified quality and safety issues around patient factors including optimal triage of patients and use of technology. We also evaluated accessibility to virtual platforms and logistics such as coordination of care for diagnostic testing. Finally, a guidance document was created and communicated to our diverse ambulatory practices to support clinicians.

CONCLUSIONS

Ambulatory virtual care delivery requires a dynamic, flexible model of care through continuous rapid-cycle process improvement to mitigate patient safety risks during a pandemic, incorporating both provider and patient perspectives.

Economic Evaluation Protocol and Statistical Analysis Plan for the Cost-Effectiveness of a Novel Australian Stroke Telemedicine Program; the Victorian Stroke Telemedicine (VST) program

Introduction: Telemedicine can address limited access to medical specialists in rural hospitals. Stroke provides an important case study because: it is a major cause of disease burden; effective treatments to reduce disability (e.g., thrombolysis) can be provided within the initial hours of stroke onset; careful selection of patients is needed by skilled doctors to minimize adverse events from thrombolysis; and there are major treatment gaps (only about half of regional hospitals in Australia provide thrombolysis for stroke). Few economic analyses have been undertaken on telestroke and the majority have been simulation models. The aim of this protocol and statistical analysis plan is to outline the methods for the cost-effectiveness evaluation of a large, multicentre acute stroke telemedicine program being conducted in Victoria, Australia.

Methods: Using a historical- and prospective-controlled design, we will compare patient-level data obtained in the 12 months prior to the Victorian Stroke Telemedicine (VST) program implementation and during the first 12 months of VST to determine the incremental difference in costs and patient outcomes at 3 and 12 months. Secondary aims include assessing the cost per additional patient receiving intravenous thrombolysis and the cost per additional patient receiving intravenous thrombolysis within 60 min. Tertiary aims include assessing the potential longer-term cost-effectiveness in the second year of the program at the hospitals to determine whether any program benefits are sustained once site coordinators are no longer employed; and modeling the potential net life-time costs and benefits from a societal perspective. Multivariable uncertainty and one-way sensitivity analyses will be performed to assess the robustness of results.

Results: Sixteen hospitals participated. Patient-level data collection including 12-month outcomes for the cohorts obtained in the first and second year of the program for each hospital was completed in January 2020.

Conclusion: The results from this real-world study with patient-level data will provide high quality evidence of the costs, health benefits and policy implications of telestroke programs, including the potential for application in other locations within Australia or other countries with similar health system delivery and financing.
