Lessons learned from implementing a surge capacity support program for COVID-19 contact management in Ontario.

Setting: In Ontario, local public health units (PHUs) are responsible for leading case investigations, contact tracing, and follow-up. The workforce capacity and operational requirements needed to maintain this public health strategy during the COVID-19 pandemic were unprecedented.

Intervention: Public Health Ontario's Contact Tracing Initiative (CTI) was established to provide a centralized workforce.

Sustainable by design: a systematic review of factors for health promotion program sustainability.

Background: Sustaining health promotion programs (HPP) is critical to maintain their intended health benefits, community capacity, and to optimize resources and investment. However, not all programs are sustained beyond their initial implementation period. This is partly due to uncertainty regarding sustainability: lack of a clear definition; infrequent use of a sustainability framework; and lack of understanding of the factors that influence sustainability.
