Final answer:
The most common factor contributing to falls in a hospital setting is the advanced age of patients, due to decreased balance, sensory impairments, and medication side effects.
Step-by-step explanation:
The question is asking which factor most often contributes to falls in a hospital setting. The factor that should be included in the program as most contributory to falls is the advanced age of patients. Elderly patients are at a higher risk of falls due to various reasons such as reduced balance and strength, vision and hearing impairments, and the side effects of medications. Other factors like wet floors, frequent seizures, and misuse of equipment by nurses also contribute to the risk of falls, but the advanced age of patients is typically considered a primary factor.
