Research agenda domains and key research areas or questions for hospital at home

Domain	Key research areas or questions
Definition of the HaH model of care	Develop a consensus statement on the definition of HaH Define a standard nomenclature for HaH Determine how the definition of HaH evolves as more care delivery services move to the community and patients' homes
The HaH clinical model	Define whether a HaH admission must originate in the hospital emergency department or inpatient service to qualify for HaH Define and test approaches to medication management in HaH Define clinical standards for HaH Define whether HaH exist as a clinical unit of an acute care hospital or can safely exist as a freestanding service not tied to a specific hospital
Measurement and outcomes of HaH	Perform comparative effectiveness studies of different HaH models and the associations between different program inputs and outcomes Define optimal study outcomes in and study designs for HaH evaluation Develop validated measures unique to HaH
Patient and caregiver experience with HaH	Development of a HaH‐specific patient and caregiver experience conceptual framework Define patient and caregiver factors associated with HaH care experience Determine effects of HaH on the patient–caregiver relationship Define role(s) of family members/caregivers in providing HaH care, if any Determine how caregivers best be educated about or trained for HaH
Education and training of HaH clinicians	Define the key competencies for HaH clinicians Define education and training for HaH clinicians Determine the phenotypes of physicians, advance practice providers, nurses, and other clinicians best suited to provide HaH care Determine whether HaH medicine and associated professional disciplines develop into a subspecialty Determine best approaches to train next generation of HaH clinicians Define how subspecialists should be trained or educated to collaborate effectively in the provision of HaH care
Technology and telehealth for HaH	Define minimum standards and appropriate dosing for technology in HaH Define barriers to using technology effectively in HaH Determine how best to integrate technology and patient monitoring into clinical workflows Determine which point of care testing HaH should employ Determine optimal balance between high‐touch and high‐technology approaches in HaH Determine the best methods to maintain cybersecurity in HaH Develop artificial intelligence approaches specific to HaH that support the technology and the clinicians using it. Conduct comparative effectiveness studies of HaH‐appropriate technologies
Regulatory and payment issues in HaH	Determine payment models and regulatory frameworks that maximize value and quality of HaH care Development of regulations to encourage safe scaling of the HaH
Implementation and scaling of HaH	Define barriers, facilitators, and approaches to scale HaH at regional and national levels Develop decision rubrics to help health systems decide on HaH implementation Define optimal organizational structures to promote scaling of HaH Determine how to help the health system transition to HaH Conduct cross‐national studies on issues related to implementation and scaling of HaH
Ethical issues in HaH	Identify a code of ethics for HaH Determine whether to employ a principles or values approach to ethical issues in HaH care Clarify how or if constructs such as of autonomy or patient consent for care evolve with care being provided in a patient's home Define ethical issues associated with clinicians in being a “professional guest” in patient's home Determine whether patients need a different bill of rights when acutely ill at home
