Cautious consideration: The Case for Selective Joint Prosthetic Replacement on the NHS

A patient is admitted with a broken hip from fall and long lie, or even a worn down knee joint, what decides whether they receive the appropriate prosthetic joint replacement surgery? Ultimately, there are professional and ethical obligations to act in the best interests of the patient, but with the NHS suffering from a multitude of economic, political, and social problems that increase the need to be selective in this decision making process, where do surgeons draw the line?

The pillars of consideration to providing this surgery involve: beneficence, assessing whether patient’s lives will get better through surgery; non-maleficence, assessing whether risks and potential complications of surgery are worth it (in both short and long term rehabilitation); autonomy, allowing patients evaluation on the most appropriate treatment including informed consent, ensuring patients are comprehensively aware of all courses of treatment and associated risks and benefits; professionalism, in adhering to the highest standards of practise; justice, providing equitable distribution and access to resources regardless of their demographic.

Working in trauma and orthopaedics, I often consider whether prosthetic joint replacement is beneficial in the context of neurodegenerative disorders. I have had difficulty in assisting patients that undergo, for instance, hip replacement and day one post-operatively forget they have undergone the surgery. This can involve mobilising prematurely, potentially jeopardizing the integrity of treatment they have received by dislocating or loosening the implant, delaying the healing process, increasing infection or thromboembolic risks, advertently causing more pain and discomfort. This occurs regularly and can be problematic, with excessive treatment and only DOLS (deprivation of liberty safeguards) to prevent postoperative complications. This can traumatise patients who aren’t aware of their circumstances leading to feeling of emotional discomfort, isolation, and lashing out against those trying to help them.

Despite obligations to provide every patient treatment without discrimination, even with ability to use longer term implants like metal on plastic for patients that expect to benefit from the replacement more (those more mobile) compared to shorter term ceramic prosthetics, how far is the surgery beneficial at all considering the cost and compounding factors to those that will not fully understand or appreciate their treatment and could potentially put it in jeopardy?

Could investment for those with neurodegenerative disorder be better spent on research that can prevent higher incidence of falls, reducing the need for surgery at the source? Could it be better invested in mitigating incidence of falls in care by providing more effective infrastructure in place for this? Could investment be better spent elsewhere where the NHS falls behind for those that may truly understand and appreciate their treatment? This decision operates on a fine line and operates on the boundary of what is ethically right.

Ultimately, I have learnt that our obligations to everyone regardless of their demographic or cognitive state are considered equal. Besides, are we not obliged to those suffering from neurodegenerative disorder that were part of the generation that built and paid for the NHS throughout their lives? However, paradoxically, I would consider higher selectivity in providing such surgical treatments as i believe it could be more beneficial elsewhere in patient outcomes and development would lead to better future outcomes for these patients.

How the NHS falls behind: the tech gap

You turn up at hospital and what is the first, most basic test that they carry out? Vital observations. From the most minor injuries to surgery and intensive care, throughout the hospital at every level, vital observations are integral to medical understanding and monitoring of the individual. They can be relatively rudimentary signal acquisition systems, relaying physical signals from the patient through a signal amplifier and analog to digital converter where electrical signals can be analysed and monitored on a computer. So how has this relatively straightforward technology become so outdated in anywhere other than the operating room, when recently in Los Angeles, California, I was presented with cutting edge, holistic, remote medical sensing technology at Massimo biotechnology?

Working throughout the RD&E Exeter and SGH Southampton Hospitals, and most recently work in Coronary Care and Emergency Majors department has raised my awareness of the failures of vital monitoring systems so highly relied upon. For instance, ECG monitoring on Cardiac units currently rely upon either static or cumbersome remote ECG monitors that can be very restricting to the patient (especially those generally mobile or that become agitated without activity), require manual operation, and generally provide minimal amount of information solely related to one requirement, in comparison to the holistic, versatile, and minimally invasive remote monitoring systems currently being innovated and sold on the market.

Currently, Massimo offer the Radius VSM which provides the ‘versatility of a bedside monitor in a wearable device’. This includes pulse oximetry monitoring, respiration monitoring and rates, noninvasive blood-pressure which have customisable intervals of observation, temperature, patient mobility and orientation monitoring providing ability to detect falls and prevent pressure sores, and ECG with 6 different waveforms. The ability to monitor these variables from the nursing desk, regardless of where the patient is, can be much more time efficient and less restricting than current methods. This must also be able to factor in for artefacts that can present themselves in readings, for instance mains interference or EMG (electricity radiated from muscle) as a result of movement.

While perhaps the NHS has equipment that will “do the job”, does it work to what could be its current full potential and reflect the incredible recent advances made in bioengineering (which could lead to improved patient outcomes)? No.

The NHS has a multifaceted problem with innovation and development. This comes down to difficulty in implementing changes to a highly decentralised and overly bureaucratic system which would require a lot of coordination and investment. Investment with a tight budget from the British taxpayer and high competition between arguably just as, if not more important medical devices and materials, proves another problem. In terms of innovation, inevitably there is a reluctance within healthcare professionals to step out of the comfort zone into a new era when the old is tried, tested, and already payed for.

Despite the NHS working at a sufficient level, how far does its ethical obligation to innovate, stretch into the modern age of technology. Patient wellbeing would improve with more accurate, less restrictive systems. Equality and access to healthcare across the country with better outcomes, improved efficiency and reduced waiting times for any individual regardless of background, would also be possible. Furthermore, innovation would be an obligation of beneficence and non-maleficence with patients best interests in mind. However, to what extent this is significant in terms of resource allocation must be up for contemplation.

Evidently now the NHS has realised their need to develop in this niche with necessary trials being launched. However, the delay in this being a priority is evidence of the NHS need to improve.
