Institute of Medicine of the National Academies. (2013). Out-of-Hospital. Crisis Standards of Care: A Toolkit for Indicators and Triggers.
This section (starting midway through the document) of the Institute of Medicine's widely referenced Crisis Standards of Care (CSC) contains detailed planning information for crisis situations which is broadly applicable to much of homecare disaster planning. The functional checklist at the end of the section may be of particular utility. (See also the ASPR TRACIE Topic Collection on Crisis Standards of Care.)
