An innovative method of carrying out lung biopsies at Barnet Hospital could free up hundreds of hospital beds and provide earlier lung cancer diagnosis by increasing tenfold the number of potentially life-saving tests carried out each year. Chest radiologist Dr Sam Hare explains why his team’s ambulatory lung biopsy method should be rolled out across the NHS:
Lung cancer is the world’s biggest cancer killer, causing more deaths each year than breast, colon and prostate cancer combined.
Worse still, despite advances in treatments, the UK still lags behind its European and North American counterparts when it comes to lung cancer outcomes.
Many patients are not seeing the full benefit of the latest therapies because of delays in diagnosis caused by the sheer amount of time it takes to get someone in for a biopsy.
This is an area where the NHS urgently needs to improve. Reassuringly, however, effective NHS innovation doesn’t always require a pioneering invention or new piece of technology. Sometimes a common sense solution that is truly patient focused is all that is needed.
I was trained in the UK to perform standard, uncomplicated lung biopsies. This is the pivotal lung cancer diagnostic test and usually involves four to six hours post-biopsy monitoring in a hospital bed, even in routine cases. If a lung biopsy patient developed a pneumothorax this would usually require a formal in-patient admission and treatment with a traditional bulky chest drain for a few days.
One of the biggest day-to-day challenges facing NHS organisations is bed and resource availability. Today nearly every standard NHS lung biopsy relies on the availability of a hospital bed for at least four to six hours.
Furthermore, the prospect of a patient being hospitalised for two to three days with a large, uncomfortable chest drain means that many patients in the UK, typically those who are older or have smaller cancers that are more complicated to biopsy, will often decline – or be declined – a lung biopsy.
Is it any wonder that that we are missing opportunities to diagnose lung cancers at an early stage?
After a year-long thoracic radiology fellowship in Canada it soon became abundantly clear to me that achieving earlier lung cancer diagnosis didn’t actually require reinventing the wheel – rather a willingness to use simple but innovative techniques already being practiced elsewhere. I returned to the NHS with my eyes open and a steely determination to innovate lung biopsy practice here.
Since 2011, Barnet Hospital – part of the Royal Free London – has performed lung biopsies on an entirely outpatient basis without the need for hospital beds. This not only means that bed-related scheduling delays have been completely eliminated, but the vast majority of patients can be discharged just 30 minutes after their biopsy.
Such creative thinking, using methodology with an international evidence-base, has permitted us to perform anywhere between 10 and 14 lung biopsies every week, whereas most hospitals of equivalent size might do only one or two.
Crucially, even if patients develop a pneumothorax, they are treated at home using a discreet, portable device called a Heimlich-valve chest drain (HVCD). The device is small enough to be concealed under the patient’s clothes and allows patients to engage in normal daily activities while it treats their collapsed lung. For some patients this has even included doing the weekly supermarket shop or being able to continue caring for a disabled partner at home.
So what is it that has finally changed to make people sit up and take notice in the UK?
Last year we were able to publish the results of our four-year study of nearly 500 ambulatory technique lung biopsies in Thorax, the country’s leading respiratory journal.
Since 2011 we have now performed close to 800 ambulatory lung biopsies and 99% of patients have been discharged within 30 to 60 minutes, including those patients who experienced lung collapse. Thanks to the Heimlich valve, pneumothorax has become a minor inconvenience for our patients, rather than a major upheaval.
Demonstrating that this approach actually works in the NHS, delivering improved patient experience as well as financial savings, in my opinion makes wider rollout a no-brainer.
Due to our innovation, Royal Free London patients are being diagnosed more quickly. Correspondingly, more patients are undergoing curative lung cancer surgery and accessing the latest lung cancer treatments.
It’s now time for the wider NHS to give patients with lung cancer the best possible chance at beating the disease by making a firm commitment to early lung cancer diagnosis.
I firmly believe that the Barnet Hospital ambulatory lung biopsy model offers an NHS-wide scalable answer that could help achieve this.
