The datasets included in this study cover the key health care services provided to patients: hospital in-patient services, community health services including primary health care, emergency health care and formal long-term care (such as nursing homes and home care services). The use of prescription medicines is a key part of the health care services offered to patients that are delivered in hospital, in other care settings and in the community to be used at home. They are both tremendously useful and highly risky products and understanding benefits and risks is essential to keeping patients healthy and safe. Thus these data are a key component of health care pathways and outcomes.
