Definitions, frameworks and commonly measured constructs in systematic reviews on sustainability of healthcare interventions (n = 25)

Frameworks (used in N = 9 reviews)	N (%)
• Scheirer (2005) Sustainability should be measured across three levels for sustainability: individual, as continuing to deliver services that are beneficial; organisation, as maintaining the programme and community, as maintaining capacity.	1 (11)
• Cekan and Zivetz (2016) Sustainability should measure if the program has incorporated a theory of change, presence of explicit sustainability goals in a monitoring and evaluation plan, methods for identifying unexpected outcomes; funding, capacity development and collaboration	1 (11)
• Moore et al., (2017) [95] Five key sustainability constructs describe individual and organisational capacity based on time, behaviour, adaptation of the program/intervention, ongoing benefits and ongoing delivery of the program/intervention	2 (22)
• Shediac-Rizkallah & Bone (1998) [96] Sustainability can be measured through maintenance of health benefits, integration of the program within an organisation and community capacity building	2 (22)
• Greenhalgh et al., (2017) [84] NASSS Framework The framework consists of 7 domains (condition, technology, value proposition, adopter system, organisation, wider system and adaptation over time) and numerous subdomains.	1 (11)
• McLeroy et al., (1998) Health related behaviour is influenced by individual factors, interpersonal factors, organisation factors, community factors and public policy factors.	1 (11)
• Lennox, Maher & Reed (2018). Consolidated framework for sustainability constructs in healthcare. Includes 40 constructs across six domains: the organisational setting, negotiating initiative processes, resources, the external environment, the initiative design and delivery and the people involved.	1 (11)
