During the COVID-19 pandemic, public health agencies implemented an array of technologies and digital tools to support case investigation and contact tracing. Beginning in May 2020, the Association of State and Territorial Health Officials compiled information on digital tools used by its membership, which comprises 59 chief health officials from each of the 50 states, 5 US territories, 3 freely associated states, and the District of Columbia. This information was presented online through a publicly available technology and digital tools inventory. We describe the national landscape of digital tools implemented by public health agencies to support functions of the COVID-19 response from May 2020 through May 2021. We also discuss how public health officials and their informatics leadership referenced the information about the digital tools implemented by their peers to guide and refine their own implementation plans. We used a consensus-based approach through monthly discussions with partners to group digital tools into 5 categories: surveillance systems, case investigation, proximity technology/exposure notification, contact tracing, and symptom tracking/monitoring. The most commonly used tools included the National Electronic Disease Surveillance System Base System (NBS), Sara Alert, REDCap, and Maven. Some tools such as NBS, Sara Alert, REDCap, Salesforce, and Microsoft Dynamics were repurposed or adapted for >1 category. Having access to the publicly available technology and digital tools inventory provided public health officials and their informatics leadership with information on what tools other public health agencies were using and aided in decision making as they considered repurposing existing tools or adopting new ones.

Objective This study examines possible bidirectional relationships between neighborhood climate (i.e., perceived neighborhood social environment) and walking behavior across a 12-month period in older Hispanics. Method A population-based sample of 217 community-dwelling older Hispanics in Miami, Florida, completed measures of perceived neighborhood climate and neighborhood walking, at two assessment time points (12 months apart). Results Structural equation modeling analyses revealed that neighborhood climate predicted subsequent walking 12 months later, such that more positive perceptions of neighborhood climate predicted more walking. Follow-up analyses revealed that older adults who resided in the top half of neighborhoods based on perceived neighborhood climate scores at initial assessment were 2.57 times as likely to have walked at least one block in the last week at follow-up, relative to older adults residing in neighborhoods whose climate was in the lower half. Discussion Perceptions of a more positive neighborhood social environment may promote walking in urban, older Hispanics.
