All about E-POS and its uses

E-POS is Novacair's preoperative screening. Read more about what exactly E-POS is here.

The patient receives a secure email containing the questionnaire and animation videos to support informed consent.

  • Completing the questionnaire takes between 5-10 minutes, depending on the patient's health status.
  • Once the questionnaire is completed, the patient is immediately shown animation videos explaining the sobriety policy, preparation for surgery and anesthesia procedure and risks.
  • After this, the patient gives a digital approval.

Once the patient is completed, the anesthesiologist determines the appropriate follow-up consultation based on the advice and report from E-POS.

It is important that the questionnaire is accessible to all target groups. Think of people with an immigrant background, the elderly but also the low-literate.

Therefore, there are several ways to complete the questionnaire:

  • Independently from home via a smartphone, tablet or computer
  • Under the guidance of a family caregiver, home care worker via a smartphone, tablet or computer
  • At the outpatient clinic via a kiosk computer or tablet
  • At the outpatient clinic under the supervision of a medical secretary or physician assistant (for those with low literacy)

Would you like to complete the questionnaire yourself? You can request that here.

By default, the questionnaire asks all necessary questions required for a safe preoperative examination. Relatively healthy patients are asked the minimum required questions. In patients with multiple underlying health problems, further questions are asked as needed.

It is also possible to add your own questions for a nursing consultation, for example.

  • The response rate of the questionnaire is about 97.5%. This is partly due to:
  • The translations (Dutch, English, Spanish, Polish, Turkish and Arabic)
  • Sending the questionnaire without logging in with DigiD (with other security assurance method)
  • Automatic reminders for patients who forget to complete the questionnaire

It is possible to see E-POS live in operation at our clients. If desirable, NovaCair can mediate this.

When picking a suitable hospital for a work visit, it is important to consider:

  • The EHR in use
  • How long the system is live

Saving E-POS depends on the current process and patient population. In FTE it varies between 30% and 60%. It is possible to have this mapped out without obligation through a 60-minute conversation. After this conversation, the following deliverables will be provided:

  • Process drawing of the current process
  • Process drawing showing an example of the work process after implementation of E-POS
  • Calculation of potential savings by job group in Excel for own assessment

You can request this call via this link. Don't want a conversation yet but want more insight into the savings? Then it is also possible to fill out the savings calculator here.


E-POS has been scientifically validated by the Amsterdam UMC. The results have been published in The Journal of Clinical Anesthesia. The study can be downloaded via this link.

There is also ongoing research on Informed Consent, among other things, by Erasmus MC. The results of this will be published when the research is completed.

Would you like to use E-POS for scientific research yourself? This is often possible at no cost. Then check out this page (there should be a new page here where people can read more about this).

E-POS is used in several hospitals and ZBCs. Experiences of these customers can be read back on our customer page.


The procurement process varies by hospital. It is wise to make preparations prior to hooking up several colleagues from support departments.

Fortunately, this does not take much time:

  1. First, find out if some other colleagues in the professional group are familiar with E-POS. It is possible to ask your NovaCair Consultant for a no-obligation presentation (duration 60 minutes).
  2. In addition, it often helps to have a brief calculation made of the potential savings. This allows you to better explain what the impact of the implementation is going to be and if it is there at all. Having the potential calculated can be supported and substantiated by the NovaCair Consultant (duration 60 minutes). More information can be found here

Depending on the SPD, E-POS uses different protocols. This information is described on the following pages: 

  • E-POS linking with ChipSoft HiX
  • E-POS Pairing with Nexus
  • E-POS pairing with Epic
  • E-POS linking with EMMA
  • E-POS Pairing CNS Connect
  • E-POS linking with other systems
