Abstract

The COVID-19 pandemic has significantly altered working practices within hospitals. This includes surgical theatres and cardiac catheter laboratories. Here we describe how we have harnessed the use of video technology to improve the running of the cardiac catheter lab in our institution, reducing the exposure of staff members to COVID-19, reducing the need for personal protective equipment (PPE) and maintaining and enhancing educational and teaching opportunities for trainees.

The problem

The cardiac catheter lab is used for many procedures requiring fluoroscopy, including angiograms, primary percutaneous coronary intervention (PCI) and pacemaker insertions. Eastbourne District General Hospital has two fully functional catheter labs. The smooth running of the catheter lab requires multiple staff members including physicians, registrars, nurses, physiologists and radiographers.1

Although some elective procedures have been postponed during the COVID-19 pandemic, urgent and emergency procedures including pacemaker insertions, generator changes and primary PCI are still mandated.2,3

The COVID-19 pandemic has posed many challenges in the catheter lab, including the following:

  • Many patients show signs of or have confirmed COVID-19 but still require an urgent procedure. This poses a risk to staff members and thus limiting the number of staff in the catheter lab is vitally important.

  • Normally more than five staff members would be in a catheter lab, making it problematic to maintain distancing rules.

  • Operators are in close proximity to the patients (within 2 metres) performing potential aerosol-generating procedures and thus procedures should be limited to only one operator. This poses the additional challenge of meeting the training needs of registrars.

  • In many cases a second opinion from another physician is needed. Normally this would require the second physician to go into the lab to review images or to give advice, again making it harder to maintain distancing and increasing exposure for staff and patients.

A solution

We sought to reduce the number of staff members in the catheter lab in line with current guidance while at the same time maintaining patient safety and retaining a learning platform for junior doctors and allied health care professionals.

We set up a video conferencing facility within the catheter lab, which allowed communication to healthcare providers outside the lab. This involved two small web cameras mounted in the catheter lab. Also, the fluoroscopy images and diagnostic recordings such as the ECG were anonymised and streamed into a custom-made software (Lifestream) to allow simultaneous viewing of all stages of the procedure (Fig 1).

Lifestream interface, combining live video streaming of the procedure together with diagnostic recordings and images.

Initially the live video was streamed over the local network to a nurse outside the catheter lab, allowing the nurse to see exactly what was happening in the lab in real time. The system also allowed communication to enable the nurse to provide equipment to the catheter lab without going inside, thus reducing exposure to COVID-19. In some cases this was extended to streaming in real time to a consultant colleague, allowing effective remote proctoring and the provision of a second opinion.

Discussion

The use of video streaming in the catheter lab has helped us to fulfil our main aim of reducing the number of staff and allied healthcare professionals in the catheter lab, enabling adherence to distancing guidelines and reducing exposure to COVID-19. This has also reduced the need for PPE, which is in high demand.

The system has also allowed us to stream procedures remotely to consultant colleagues outside the catheter lab. This has been particularly advantageous as many cases require input from two or more consultants, for example when deciding whether a patient should go on to have cardiac surgery or a stent insertion.

One of the challenges of the COVID-19 pandemic faced by many procedure-based specialties is how to provide learning experiences to trainees. The system has allowed consultants to proctor cases remotely, thus providing support and confidence to trainees.4 The system has also been set up on a dedicated server, enabling all cases to be recorded. This provides a valuable teaching aid and may potentially be used for auditing or root cause analysis investigations in the future. The system may be used in any procedural setting including operating theatres and endoscopy units.

The COVID-19 pandemic has accelerated the use of telemedicine by healthcare professionals. The use of applications such as Zoom or Microsoft Teams has exponentially increased, replacing face-to-face meetings and clinic appointments.4 The system described can be implemented by transferring the video graphics array output from the cameras, fluoroscopy screens and ECG monitoring to a single computer which has screen sharing capability in a video call.

The uptake of telemedicine has been slower in situations in which there is patient identifiable information. This barrier was overcome by using the Lifestream system to crop patient-identifiable information in the streaming feed, thus anonymising all data and making the system GDPR-compliant.5 As a result, with patient consent, the stream may be shared in a video call with colleagues remotely within other applications such as Microsoft Teams.

The use of robotic techniques has also been advocated and used during the COVID-19 pandemic, for example for gynaecological procedures.6 This has the advantage of also protecting the primary operator. However robotic systems are not available in all hospitals and their high cost prevents rapid uptake; for example, the CorPath GRX system used for robotic PCI costs in excess of $650,000.7

Conclusion

The described video streaming system has allowed the department to effectively manage COVID-19 patients in the catheter lab without compromising patient safety. In addition, it has reduced staff exposure and provided a valuable learning tool. The COVID-19 pandemic has accelerated our use of video technology, which will have benefits in the future, allowing remote proctoring and multidisciplinary team meetings to occur remotely without delay.
