Assessing scale-up of mHealth innovations based on intervention complexity

From the article abstract findings: "The authors based their findings on literature and discussions with key informants involved in the programs. For both interventions, introducing SMS reduced barriers to effective and timely delivery of services by simplifying the tracking and analysis of data and improving communication between healthcare providers. However, the primary implementation challenges for both interventions were related to broader program delivery characteristics (e.g., human resource needs and transportation requirements) that are not easily addressed by the addition of SMS. The addition of SMS technology itself introduced new layers of complexity."
