Unplanned admissions for chronic conditions such as asthma, diabetes and epilepsy reached 1,742 per 100,000 people in NHS Bradford CCG in 2011/12, compared with just 215 per 100,000 in NHS City and Hackney CCG.
The NHS Information Centre highlighted the variation as it launched a new set of 16 CCG Outcomes Indicators to track CCG performance.
The figures highlight the challenges facing CCGs as they bid to shift care away from hospitals and into the community.
The progress measures, previously called the Commissioning Outcomes Framework, add to a bank of indicators spread across five domains, including preventing premature mortality, improving quality of life for patients with chronic disease, and improving their experience with the NHS.
NHS England, formerly the NHS Commissioning Board, will use the indicators to hold CCGs to account over performance, and reward progress through the quality premium.
The GPC has previously warned that the scheme will increase the 'target culture' in the NHS and could harm patients.
