  • Note: CDSS = clinical decision support system, NA = not applicable, PCP = primary care provider, PDA = personal digital assistant, SMS = short message service (text messaging), “–” = not reported.

  • * Studies are ordered by provider-to-patient communication; they are ordered by any use of Web portals, SMS text messaging, automated communication, smart device, computer software, videoconference, email, customized patient Web pages, video messaging, smartphone application, telephone and letter. A smart device is any computerized device specifically developed to collect and transmit patient data to health care providers. Web portals are websites where patients upload blood glucose or other clinical data and share these with their health care providers; many times providers also use Web portals to provide feedback to patients. CDSS systems receive data from patients and automatically respond using computer algorithms in a variety of ways, such as precomposed messages sent as SMS text messages to patients (Kim 201095), alarms sent to the providers when abnormal data are received (Gomez78), analyzed data reports sent to providers (Quinn125) and voice feedback over the telephone to patients (Schillinger131). Other components not mentioned in this table include psychological support, such as support for depression, smoking cessation and behavioural therapy.

  • Indicates an approximate frequency of feedback. For example, we used “~ daily” rather than 3 times per week for Lim102; “~ every 2 wk” replaced 14 times per 6 months for Eakin,67 and 11 times per 6 months for Munshi;112 “~ monthly” replaced 5 times per 6 months for Blackberry55 and Frosch,73 and 10 times per year for Walker;147 and “~ every 2 mo” replaced every 7 weeks for Young.155
