National Joint Registry press release: 40% of NHS Trusts and Health Boards 'red' rated for submissions to mandatory National Joint Registry
Local NHS Trusts and Health Boards could be putting the long-term safety of patients at risk in failing to comply with the now-mandatory NJR.
The NJR records data on hip, knee, ankles, elbow and shoulder replacements for England and Wales. Analysis of this information for all patients provides clinical evidence to surgeons and the wider healthcare community in order to protect patient safety and improve patient care. With over 1.3 million records, the NJR is the largest registry of its type in the world.
For the first time, today's publication of the 9th NJR Annual Report includes individual hospital data which reveals that 40% (59 out of 148) of relevant NHS Trusts and Health Boards submitted between 0% and 79% of the hip and knee replacement operations they performed in 2011 - classifying them as 'red' in the NJR's red, amber, green analysis classification.
The Department of Health made NJR compliance mandatory as of 1 April 2011, and the figures above cover the period 1 January 2011 to 31 December 2011. But while the first three months of 2011 were non-mandatory, during this time hospitals were strongly encouraged to comply fully with the NJR.
NJR National Development Lead Elaine Young comments: "The data we receive are essential for healthcare professionals in deciding which prostheses and procedures are right for which patients at what time to ensure patient safety. The fuller the picture provided by hospitals, the more robust the data quality, which can only lead to further improvements in patient care."
Young continues: "The situation has improved since mandation and many best practice examples exist. But, going forward, data from English NHS Trusts and Welsh Health Boards failing to comply will be escalated to the regulators, the Care Quality Commission and Welsh Government respectively. We would encourage any hospital in need of support to contact the NJR."
The NJR is also for the first time issuing individual annual reports to NHS Trusts, Health Boards and independent and private sector management covering mortality by unit (individual hospital) and joint replacement survivorship (how long a device lasts before it needs replacing or modifying) by unit and surgeon.
Professor Paul Gregg, Vice Chair of the NJR Steering Committee and Chair of its Surgeon Outlier Sub-committee added comments: "This will play a vital role in improving patient safety and overall outcomes of joint replacement surgery. However, the NJR relies on hospitals to help maximise data quality - it is therefore highly disappointing that not all Trusts and Health Boards are currently registering all operations as this will have a negative effect on this process. If managers want a precise picture of what is happening in their units, they must act now and not wait until issues are escalated."
Other indicators for the new Trust-, Health Board- and hospital-level data analysis include patient consent and linkability as well as mortality rates, hip revision and knee revision rates for the period 2003 (when the NJR began reporting) to 2011.
Hip joint replacement: key trends 2011 >
For hip replacements, the average body mass index (BMI) score for men and women was 'overweight' and the score has consistently increased within that category since 2004 but is consistently lower for women than men. In the same period, the proportion of patients with a normal BMI has fallen by 7%.
Correspondingly, the proportion of patients rated fit and healthy (P1 - an ASA grade rating general health and fitness to undergo surgery) decreased again to 15%, from 16% in 2010 and 37% in 2003.
Despite some anecdotal suggestion that hip replacement patients are getting younger, NJR data describe a consistent age range of patients. For example, patients under the age of 50 represent 6% of the total which has not changed since 2003 and patients over the age of 80 remains around 14%. The average age of a hip replacement patient was 67.2 - unchanged from last year.

Knee joint replacement: key trends 2011 >
For knee replacements, the average BMI score was again 'obese' for men and women - 30.82 up from 30.66 last year and with year-on-year increase since the average reached 'obese' in 2008. Women have scored a consistently higher BMI since 2004, the opposite trend to that shown for hip replacements. Again, the proportion of patients rated fit and healthy prior to knee replacement surgery has fallen by 1% from 12% in 2010 and since 2003, a decline from 31%.
