Practices with poor prescribing performance more likely to prescribe homeopathy

Clinical workload for general practice in England rises 16% in seven years

Is general practice in England nearing 'saturation point?' Oxford University-led research published in the Lancet suggests it might be.

New test for bowel cancer could save lives through early detection

A new screening test in primary care is being hailed as the most efficient way to indicate risk of colorectal cancer.

With the era of open information now underway, healthcare researchers now have access to promising new threads of knowledge - known as "big data" due to both its volume and complexity.

By bringing together data from thousands of patients and GP consultations, researchers have the ability to source the most reliable evidence for clinical and health service decision making. Several groups in the Nuffield Department of Primary Care Health Sciences are using big data to generate new insights into areas of primary care where there is most need. For example, through the EBM Data Lab's Open Prescribing project, raw data from the NHS on what drugs each GP prescribes has been turned into a series of easy-to-read dashboards, so any patient or health service decision maker can explore it - supporting safer, more efficient prescribing.

In addition, recent research by the department using data from 398 GP practices in England (equivalent to 2.5 million patient years of observation) showed that clinical workload for GPs in England had risen by 16% between 2007 - 2014, as well as several other important insights into patterns of GP consultations in England.
