The use of video analysis technology such as Codimg is an emerging discipline which can bring improvements to many aspects of healthcare and is already being utilised in hospitals all around the world to help provide the best possible care to patients.
But, being a fairly new concept, there are many questions surrounding video analysis and what exactly it can do. In this article, we’ll attempt to define what video analysis is and show some practical ways it can be used in healthcare centres and hospitals.
As we said in the intro, video analysis is an emerging discipline, but one that has proved invaluable in many walks of life.
Take sport, for example, where video analysis has probably seen the greatest uptake. There are very few professional clubs that don’t have a video analysis department nowadays. In addition to this, there has also been some recent movement in the fields of education and training.
And, obviously, it’s becoming more and more common in the field of healthcare.
So what does it involve?
Basically speaking, video analysis does exactly what it says on the tin. You film a scenario and analyse the resultant video. This analysis is then used to identify areas of weakness where practice can be improved.
Now, this might sound like something that you could do with a pen and piece of paper, right? And it is to a point. But the big advantage of specialist video analysis software is that you can collect massive amounts of data, filter it and use it in a way that is extremely easy, quick and reliable.
Let’s look at the typical process for doing this…
Generally, there are three main stages to the video analysis process. These are:
• Observation and Tagging
In this video, Esther León, Coordinator of Research, Development and Innovation in the Simulation Lab at the University of Barcelon explains more about this process:
The observation and tagging stage begins with creating a Button Template. The template contains all the observation criteria you have previously agreed with your team and is split into Categories and Descriptors.
You are observing a group of students doing medical simulation in the surgical theatre. One aspect of your brief is to check that hygiene standards are maintained throughout and all protocols are followed. To this end, you have created a “Hygiene” template in Codimg. This contains Categories which are essential to good, hygienic practice.
You create various buttons which have names such as “Scrubs”, “Gloves”, “Sterilised Equipment”, “Disinfection”, etc. These will be your main Categories.
You then create another group of buttons. These will be your Descriptors. They describe how the Categories are done. You create 3 rating buttons “Good”, “Unsatisfactory” and “Ok”. You also create a Descriptor button for each team member taking part in the simulation and their role, e.g. “Jen Smith - Surgeon”, “Bobby Fletcher - Anesthesiologist”, “Pete Brown - Head Nurse”, “Simone Michaels - Assistant”.
You notice during the simulation that Bobby Fletcher handles the equipment in a manner which leaves them in an unsterilised state. When you see this you press the buttons Sterilised Equipment > Booby Fletcher > Unsatisfactory. This, in turn, “tags” that specific moment in the video so that you can rewatch it instantly without having to search through hours of tape later.
You have 5 different templates for different aspects of the simulation that you want to evaluate.
And this is how you form the basis of your analysis. By tagging actions on the video you build up a database of information on how the students have done in the simulated event. This may seem like a long winded process, but we assure you that it is quite easy to create the button templates with Codimg and, with a little practice, you will be able to tag the video quickly and efficiently.
Which brings us to the next step in the process…
This is the part where you use all the data you have collected to evaluate the success of the scenario being observed in order to give recommendations.
You have a database of tagged video clips which can be searched using the Codimg Data Matrix, where all your Categories and Descriptors are placed in an intersecting grid. For example, if you want to find all the Unsatisfactory, Sterilised Equipment actions of Bobby Fletcher, you find where these intersect on the grid. A click on the appropriate section will pull up all these incidents in a second.
You can filter the information in any way you find desirable.
Other methods of analysis include the powerful Codimg Dashboard, which will show you a visual representation of the data you have collected in an easy to read fashion.
You can also export your data to Excel for a more traditional visualisation of your data.
So there you have it, all the data and video clips you need for completing your analysis at your fingers.
Obviously, you will want to share your conclusions, either with colleagues or in debriefing sessions after a simulation has been complete.
And this is where the video production tools in Codimg come into play. With Codimg Presentations it is very easy to create a list of actions you want to share, and produce a video based on these. A simple click on any tags you have made to the video will add that action to the list and, once you have everything you need, another click will produce a seemless video from that list in .mp4 format for easy sharing.
Within the videos, you can add additional information. For example, you can add drawings on top of the videos using the in-built telestrator, PowerPoint slides to separate chapters, add your own audio notes or music and many more things.
All this leads to professional, informative, objective videos which can be used in meetings and debriefings in order to make recommendations for improvement.
So, why should you be using video analysis? Let’s dive a little deeper…
So, why should you be using video analysis? Let’s dive a little deeper…
Because you decide the observation criteria and create the Button Template yourself, Codimg can be used to analyse any scenario which can be observed. In the field of healthcare, this may include:
• Any type of simulation
• Medical Research
• Actual surgery
• The admittance process
• Delivery of physiotherapy
• Care in the ward
+ many more situations.
We all know the old axiom “the camera doesn’t lie” and there was never a truer word said. Codimg gives you real, irrefutable evidence when it is needed in debriefing sessions, OSCE evaluations, assessments or even disciplinary procedures.
The goal of using video analysis should be to identify areas of weakness within the organisation or team. Codimg allows you to collect the evidence which can really affect change.
As Pablo Jorge, Cardiologist and Advanced Clinical Simulation Instructor at the University Hospital of the Canary Islands, says, “The power to analyse and reflect on actions taken in a safe environment such as the simulation lab is a fundamental tool in overcoming the culture of error”.
Ok, what you read about the process might sound daunting, but we assure you that Codimg is actually a fairly simple tool to use. In fact, most people will be able to get up and analysing with a few hours practice with minimal instruction.
Of course, there is a learning curve and it might take you a bit longer to grasp some of the more advanced features on offer, but the intuitive nature of Codimg allows for all kinds of experimentation.
At the same time, we at Codimg, pride ourselves on our customer and after sales service. We will be by your side every step of the way and be available to help you get the most out of your software.
You don’t need a lot of equipment to get started with video analysis. In fact, a basic set up of a computer and camera will get you up and running.
Now might also be a good moment to mention our app for iPhone and iPad, Codimg View.
Codimg view lets you film and tag the video at the same time, directly from the app. This means that there is very little to set up before you start the analysis.
Of course, this is most useful for the observation stage of your analysis. For the second and third stages, you will need to transfer the data collected through your iPad to your desktop for further analysis and video production which, fortunately, is a very easy process. One click will transfer all your videos and data through a wifi connection.
According to Óscar Martínez, Gynaecologist and Head of Simulation and Obstetric Emergencies at Puerta de Hierro Hospital in Madrid, "Codimg allows for clear evaluation of a simulation. Simple, practical and very portable. It eliminates the need for large equipment and large rooms. It allows us to simulate anywhere. It democratises simulation."
Although perhaps not available in EVERY hospital in the developed world, the trend is definitely headed in that direction.
As with every new discipline, the most cutting edge and innovative healthcare centres are at the forefront of picking up the video analysis baton and running with it. This will eventually be passed on through the ranks until, eventually, video analysis becomes as common a fixture in healthcare as the stethoscope.
Another point to mention is that people enjoy using Codimg. We have noticed that students in particular really respond to the innovative use of technology and it has huge value as a self-evaluation tool.
At the end of the day, why are we doing this? Codimg isn’t just another Big Brother, pointing a camera at your working practice and hoping to catch you out.
No, this is a LEARNING tool.
And, however much we might think it, none of us are perfect. We could all benefit from seeing our mistakes and using that knowledge to improve our working practices, whether you work in a classroom, store room or football field.
But in a hospital, this is especially true. The ability to learn from your mistakes will not just improve efficiency, it can also save lives.
As Prof. Manuel Maynar, Scientific Director of Medical Technology at the University of Las Palmas, "Technology has been developed so the doctor can dedicate more time to his patients".
