Project Main Description

The last two decades have seen an unprecedented growth in initiatives aimed to improve patient safety and quality of care. For the most part, however, evidence of their impact remains controversial. Quality of care interventions should not be implemented without a strategy for continuous monitoring of their effect. Routinely collected data could be leveraged to aid in this important role.

We have identified two types of temporal patterns of the safety of hospitalised patients: long-term trends related to changes in clinical practice and healthcare policy; and shorter term patterns related to variations in workforce and resources (such as the ‘weekend effect’). In General Practice, one of the major identified patterns relate to inappropriate response by doctors to conditions such as very high cholesterol, high blood pressure or uncontrolled glucose levels, which although not acute, pose serious short to long term risks to health, and require immediate action and follow up. In this research project, we use administrative datasets and Electronic Health Records (EHRs), to identify which groups of patients are at high risk of harm.
