Measuring health ageing - expanding the use of the HelpAge Health Outcomes Tool (HOT) This programme aims to advance existing health and care programmes through improved data collection and analysis on older people's health and well-being and lay the foundation for the sustainability and scalability of such work in Africa and Asia related to SDG #3 (Health and Well-being for All) and specifically non-communicable diseases (NCDs).  It comprises five sub-projects, being: 1. Collaborating for Health: using a systematic process of designing and implementing health solutions with older persons, to strengthen our health programmes and policy advocacy work through a more collaborative and integrated approach that is data informed, community based and people-centered. Activities will be run in India, Tanzania and Uganda. 2. Technology platform: to build and publish an interactive online data dashboard accessible to all stakeholders with an interest in healthy ageing. 3. Sustainabilty and scalabilty plan, a cross-regional training programme in Thailand to develop a plan for how to continue integrating the Health Outcomes into health programming in the HelpAge network. 4. Health Outcomes Tool Data Collection in the Philippines. 5. Policy Impact, to raise awareness of the value of the data and  results generated from the healthy aging projects, make available  our findings to the SDG M&E data agenda and dicussion;  and continuing to promote the use of the health outcomes tool by more organizations. 1. Collaborating for Health: i) Improved understanding of how to develop data informed and co-designed policy and programme interventions for health of older people in low and middle income countries (India, Tanzania, Uganda). ii) Strengthen collaboration around data on health of older people between HelpAge Network members. 2. Technology platform: i) Future Health Outcomes Tool data is collected digitally. ii) All new HOT data is systematically cleaned using the HOT data management system. iii) HOT data safely stored in secure environment; respondent's integrity never compromised. iv) Increased access to data on older people in LMICs both within the HelpAge network and externally to support SDG Goal 3 and 10 in providing improved data on older people to reduce inequalities in service provision. 3. Sustainabilty and scalabilty plan: i) HelpAge Network members in Latin America, Africa and Asia can independently implement the Health Outcomes TOOL as a useful MEL tool in their work. ii) Increased knowledge and understanding of the Health Outcomes Tool among HelpAge offices and partners in Asia. iii) Africa and Asia teams can easily implement the Health Outcome Tool in its digital format 4. Health Outcomes Tool Data Collection in the Philippines: i) To collect Health Outcomes Tool Data from 300 respondents in the Philippines. ii) To cContinue to validate, evaluate and improve the Health Outcomes Tool iii) To generate local data on older people's health and wellbeing to be used in the Measuring Healthy Ageing global analysis as well as in programme, policy and advocacy work in the Philippines. 5. Policy Impact: i) To bring together healthy ageing and international development sectors. ii) To share results from healthy ageing studies and the actions taken based in these results to further strengthen collaboration and influence policy.
