Final answer:
A nursing home facility must obtain approval from the pharmacy and therapeutics committee or equivalent authority for changes to the institutional formulary.
Step-by-step explanation:
A nursing home facility must obtain the pharmacy and therapeutics committee's approval, or equivalent authority, for any subsequent change made to a nursing home facility's institutional formulary. The institutional formulary is a list of medications approved for use within the facility, and changes to this formulary require oversight to ensure that they meet regulatory standards, are evidence-based, and align with best practices in patient care. Formulary management is an important aspect of healthcare administration in long-term care settings, as it influences drug therapy quality, medication safety, and overall healthcare costs.
