What evidence exists that consumer health informatics applications impact health care process outcomes?
Very few studies evaluated the impact of CHI applications on health care processes (Table 1). Measures included monitoring and therapeutic adherence, and health care utilization. The quality of these trials was variable, ranging from moderate to very low, as measured by the Jadad4 criteria for RCT quality (Appendix F, Evidence Table 1). Postintervention followup duration varied from 12 weeks up to 1 year. The study results suggested a positive effect of CHI applications on monitoring and therapeutic adherence, and health care utilization.
