Final answer:
There are significant risks, such as medical errors and adverse drug reactions, when a patient does not share their health records across different healthcare facilities, leading to compromised care quality and patient safety.
Step-by-step explanation:
There are significant risks associated with not sharing personal health records between different medical facilities. Without complete records, there is a higher likelihood of medical errors, such as prescribing contraindicated medications or duplicating tests. Additionally, the lack of records can result in incomplete medical histories, which can compromise the quality of care and patient safety. Sharing health information also facilitates better coordination amongst healthcare providers, which is crucial for continuity of care and preventive measures. In Tony's case, not sharing his VA records with his local healthcare providers, or vice versa, he becomes more susceptible to the risks of miscommunication in his healthcare, which can lead to adverse drug reactions, improper treatments, or overlooked health conditions that could potentially be life-threatening.
