Comment on “Effectiveness of a Community-Based eHealth Program on Self-Care, Cognition, and Health Outcomes of Older Adults With Chronic Diseases”

Wu et al1 evaluate a pragmatic, hybrid community-based eHealth program (CeHP) targeting self-care, cognition, and healthy aging in older adults with chronic disease. The trial's community grounding and multimodal delivery are timely and the positive signal for processing speed (Symbol Digit Modalities Test) and healthy aging is encouraging. Several methodological and analytic considerations, not fully addressed in the report, deserve attention to sharpen causal inference and to guide scaling.
