Beyond Average Results in Hypertension E-Support and Self-Management: Three Pilot Studies With Social Learning

Hypertension is a major risk factor worldwide for early death. Well-established interventions like the Dash diet on average have modest results (5 mmHg systolic and 3 mmHg diastolic pressure improvement). We compare three employee eHealth intervention pilots with results that are three to six times larger, analysing them for eSupport design lessons. In these pilots, various tools and daily microlearning strategies have been used. Small-scale Self-Management Support (SMS) groups for hypertension control foster high degrees of learning, interaction, and personalization. Average blood pressure improvements in the pilots were 161/112 to 129/90 mmHg, resp. 145/92 to 126/86 mmHg, and 155/95 to 139/85 mmHg. User evaluation (n=20) showed the importance of core SMS components: information transfer, daily monitoring, promoting health competences and follow-up. A cross-case finding is that more daily social learning and ICT-enabled microlearning feedback increases success: for competence building and for blood pressure results.
