COVID-19 pandemic poses challenges to the healthcare systems worldwide, which soon exponentially strained hospitals' systems and resources, leading them to challenge dilemmas. Meanwhile, the Philippines has made remarkable emergency response efforts against this pandemic but was exhausted due to the multiple healthcare concerns that needed to be addressed. Listening to hospitals' heads and nurse managers about their strategies drove this study to realize its aim to develop a framework for hospital responses during health emergencies. Triangulation was used in data gathering anchored on Glaser and Strauss and Charmaz's constructivist grounded theory. Careful analysis, constant data comparison, theoretical sampling to ensure the saturation of categories, and generating theory intimately linked to and grounded in the data are imperative for qualitative research. Concurrent collection and data analysis assure mutual interaction between what is known and what one needs to know, along with theoretical thinking, which provides emerging ideas that are reconfirmed as new data. The research questions were answered by documentary analysis, ZOOM's virtual interviews, and focus group discussions. A purposive sampling of thirty participants comprised ten participants from hospitals in the three main islands of the Philippines, wherein eventually, thirty participants were reduced to fifteen. Hospitals have a high level of preparedness for health emergencies, and a sustainable framework for the pandemic and other health emergencies is developed in a 5-point domain: operations, morale, infrastructure, finances, and innovations.
