Step-by-step explanation:
The specific number of annual nursing home physician visits required can vary by regulatory requirements, facility policy, patient need, and physician discretion, but there is no universally mandated number given in the provided reference information. However, based on the provided studies related to healthcare statistics, such as the average number of doctor's visits and senior citizens' opinions on yearly checkups, we can deduce the recognition of regular medical assessments.
