A research study could require additional resources within the study design that would need to be taken into consideration during your review process. Non-standard treatment could have resource implications for you. These need to be addressed before you agree to participate in a study.
It is your responsibility to ensure any extra costs are not a risk for your organisation or are covered by the study funder if there is one.
Additional information on resources may be available within the Toolkit For Care Home Research, however this toolkit doesn't take into consideration any research governance requirements: http://www.dendron.nihr.ac.uk/enrich/
