Telehealth for women's preventive services for reproductive health and intimate partner violence: a comparative effectiveness review.
This comparative effectiveness review was conducted on the effectiveness and harms of telehealth interventions for women's reproductive health and intimate partner violence (IPV) services. A literature search was conducted for randomized controlled trials (RCTs) and observational studies of telehealth strategies for women's reproductive health and IPV versus usual care for the period July 2016 to May 2022. Eight RCTs, 1 nonrandomized trial, and 7 observational studies were included (7 studies of contraceptive care and 9 of IPV services). Telehealth services demonstrated similar care as usual care for contraceptive use, sexually transmitted infections, and pregnancy (low strength of evidence [SOE]). Evidence on abortion was insufficient. Outcomes were also similar between telehealth and usual care interventions to replace or supplement IPV services and comparators for repeat IPV, depression, posttraumatic stress disorder, fear of partner, coercive control, self-efficacy, and safety behaviors (low SOE). Telehealth barriers identified included limited internet access, digital literacy, technical challenges, and confidentiality concerns. Safety strategies increased telehealth use for IPV services. Evidence lacked on access, health equity, or harms.

TELEmedicine as an Intervention for Sepsis in Emergency Departments: a multicenter, comparative effectiveness study (TELEvISED Study).
Sepsis is a life-threatening infection that affects over 1.7 million Americans annually. Low-volume rural hospitals have worse sepsis outcomes, and emergency department (ED)-based telemedicine (tele-ED) has been one promising strategy for improving rural sepsis care. The objective of this study was to evaluate the impact of tele-ED consultation on sepsis care and outcomes in rural ED patients.

Mobile-enhanced peer support for African Americans with Type 2 diabetes: a randomized controlled trial.
This study compared the effectiveness of a community-based diabetes self-management education (DSME) plus mobile health (mHealth)-enhanced peer support intervention to community-based DSME alone for African American adults with poorly controlled type 2 diabetes. This randomized controlled trial took place in Jefferson County, Alabama within a safety-net healthcare system with a group diagnosed with type 2 diabetes and hemoglobin A1C ≥ 7.5%. The intervention group reviewed community-based DSME plus 6 months of mHealth-enhanced peer support, including 12 weekly phone calls, then 3 monthly calls from community health workers. The control group received community based DSME only. Primary outcomes were lower A1C and secondary outcomes were lower diabetes distress, depressive symptoms, self-efficacy or confidence in their ability to manage diabetes, and social support. Of 120 participants selected, 97 completed the study. Both groups experienced clinical meaning reduction in A1C. Participants in the intervention group experienced a significantly larger reduction in diabetes distress compared to the control group.

A framework for classification of electronic health data extraction-transformation-loading challenges in data network participation.
The researchers conducted key-informant interviews with data partner representatives to survey the Extract, Transform, Load (ETL) process challenges faced in clinical data research networks (CDRNs) and registries. The paper concluded that overcoming ETL technical challenges requires significant investments in a broad array of information technologies and human resources. Identifying these technical obstacles can inform optimal resource allocation to minimize the barriers and cost of entry for new data partners into extant networks, which in turn can expand data networks' inclusiveness and diversity.

A digital architecture for a network-based learning health system: integrating chronic care management, quality improvement, and research.
The authors collaborated with the ImproveCareNow Network to create a proof-of-concept architecture for a network-based Learning Health System. This collaboration involved transitioning an existing registry to one that is linked to the electronic health record (EHR), enabling a “data in once” strategy. This required automating a series of reports that support care improvement while also demonstrating the use of observational registry data for comparative effectiveness research.
