An advance directive Pennsylvania is a legal document that allows individuals to communicate their healthcare wishes and designate someone to make medical decisions if they become unable to make or communicate those decisions themselves. In Pennsylvania, an advance healthcare directive may include a living will, a healthcare power of attorney, or a combination of both. A living will can outline preferences regarding life-sustaining treatment, while a healthcare power of attorney allows a person to appoint a trusted healthcare agent. Creating an advance directive can help families and healthcare providers understand and follow a person's wishes when important medical decisions need to be made.
