Essential Reading on why OpenSource software is the only sustainable answer to NHS IT woes

It is rather surprising that it is only this week that I have come across the writings of Eric S. Raymond who’s seminal paper ‘The Cathedral and the Bazaar’ in 1997 was credited with accelerating the open source movement and was an important factor in Netscape’s decision to opensource its browser.

I highly recommend reading the following essays all which can be found here. I’ve provided pdf versions below.

  1. The Cathedral and the Bazaar [pdf]
  2. Homesteading the Noosphere [pdf]
  3. The Magic Cauldron [pdf]

In combination these 3 papers set out the sociological, economical and philosophical arguments for open source.

After reading them, I more convinced than ever that it is in the interest of the NHS to create/ procure opensource software by default. It is the *only* way that the quality, reliability, security, longevity and affordability can be assured.

A simple app for counting Respiratory Rate

The respiratory rate (how many times you breathe in one minute) is a very sensitive indicator on whether a patient is well or unwell. It is a vital part in all early warning scores. Indeed, it is often the first parameter that becomes abnormal.

Unfortunately, this is also a parameter is measured inaccurately and often omitted by healthcare professionals.

Reasons (and excuses) include:-

  1. Most bedside observation machines do not produce a number that people can write down unlike the Heart Rate, Blood Pressure, Oxygen Saturations
  2. Requires the clinicians (often healthcare assistants) to count how many breaths a patient takes per minute. Over 30 patients, this observation along can take 30mins. (people get lazy). The one minute is recommended is because unlike our pulse our respiratory rate can be quire irregular. (unless you are breathing very fast then it becomes more regular.)
  3. You need a watch with a secondhand/ stopwatch

As more and more hospitals progress towards digital collection of observations on smartphones, I’m proposing a simple application that counts respiratory rates that is accurate and that will require minimal ‘skill’ and training.

This is how it works:-

  1. Start the app
  2. It will have a BIG button in the middle of it that just says ‘Press here every time the patient breaths’
  3. The program will *figure* out how regular the patient is breathing to determine the length of time the observer needs to count. For eg. if the patient is taking 5 secs btw breaths and is very regular, 30 secs may be enough. But if it is 10secs, 1 min or more is required. Conversely if something is breathing every 2 secs, 15 secs of observation is more than enough. The accuracy of this algorithm can be refined in a field study.
  4. The app, gives you a respiratory rate
  5. THAT’s it

This will be simple enough to integrate into a observation recording tools like WardWare.

It is also simple enough to teach patients and their relatives how to do this themselves.

There are apps out there that can use the iPhone camera and/or motion sensors to do the same but that is much more complicated, less accurate and will require clearly defined hardware requirements. They will also have infection control issues.

Who wants to have a go, else I’m going to be proposing this for the next NHS Hackday
