Challenges in evaluating telehealth through RCT-the problem of randomization

Area of Science:

• Health Services Research
• Digital Health
• Healthcare Evaluation

Background:

• Telehealth is proposed to manage increasing healthcare demands and improve care delivery.
• Evaluating telehealth's impact on health and care outcomes via randomized controlled trials (RCTs) is debated.
• Existing research highlights challenges in telehealth effectiveness assessment.

Purpose of the Study:

• To investigate practical and methodological issues affecting telehealth evaluation.
• To identify barriers to using randomized controlled trials (RCTs) for telehealth assessment.
• To inform future telehealth evaluation strategies in healthcare.

Main Methods:

• A qualitative longitudinal case study was conducted in the UK.
• Data collection involved focus group discussions and interviews.
• Thematic analysis was used to analyze the collected data.

Main Results:

• Significant practical challenges hinder telehealth evaluation through RCTs.
• Methodological limitations complicate the assessment of telehealth effectiveness.
• The study identified key issues impacting the validity of RCT-based telehealth evaluations.

Conclusions:

• Standardized RCT approaches may not be fully suitable for evaluating telehealth in diverse healthcare settings.
• Addressing identified practical and methodological issues is essential for robust telehealth evaluations.
• Understanding these challenges is vital for deploying appropriate evaluation strategies and ensuring telehealth's successful integration into healthcare.
