1. 8215-Preoperative examination (EN)

Preoperatief onderzoek

A preoperative examination is required as you will soon be undergoing an operation. To ensure that you are well-prepared for the operation, you will have an appointment with the pharmacy assistant (if you are taking medication), the anaesthetist and the nurse. The appointments will take place at different times and by telephone. Before we can call you, it is important that you prepare for the appointments at home. As part of this, you will need to complete a questionnaire and give permission for your medication data to be shared with the hospital.

Your appointment dates can be found in 'MijnIsala' (MyIsala) under 'Afspraken' (Appointments). We will contact you by telephone. Please note that we will call you from an anonymous number.

MijnIsala is the online patient portal for all Isala patients who have DigiD. The portal is available 24 hours a day, 7 days a week. You can log in to with your DigiD and confirm your registration via an additional text message verification. You can also log in with the DigiD App. If you don't have DigiD yet, please bear in mind that it takes five working days to request this.

Preparing for the appointment at home

We ask that you prepare for the appointment in advance. The appointment can only take place if you have already completed everything and have the correct information to hand. You will need:

  1. A completed digital questionnaire about your health. You can complete this questionnaire at home using
  2. An up-to-date overview of the medication you are taking. You can give permission to share your medication data with the hospital using
    Your doctor and pharmacy can share your medical data with the hospital. This data exchange takes place via the 'Landelijk Schakelpunt, LSP' (National Exchange Point). Your data is only shared if you agree to it. If you would like to know more about this, check whether you have already given permission or you would like to give permission, go to the website. You can also ask your pharmacy or doctor about this.
    If you do not want to give permission, you must request the overview from your pharmacy yourself. In this case, you will be responsible for providing accurate information.
  3. If you are using a Baxter roll: the Baxter toedienlijst (administration/dispensing list).
  4. An overview of the medications that you buy yourself at the pharmacy.
  5. The names and phone numbers of two contacts.

The digital questionnaire about your health

The questionnaire contains questions about your health. You must have completed the questionnaire before your appointment.

Complete the questionnaire at home using MijnIsala

It is possible to complete the questionnaire at home using Once logged in, go to 'Vragenlijsten' (Questionnaires). The questionnaire takes about 20 to 30 minutes to complete. Please note that you must complete the questionnaire in one go, as you will not be able to save your progress and return to it later. If it is not possible to complete the questionnaire using MijnIsala, you can complete it using one of the computers at the hospital.

Conversation with the pharmacy assistant

(If you are taking medication)
The pharmacy assistant will review the medication you are taking. He/she will also ask about any allergies and whether you experience significant side-effects when taking certain medications.
Do not forget to mention the non-prescription medication you are taking in the telephone conversation. This includes things like paracetamol, antacids or vitamins that you can buy without a prescription at your drugstore or pharmacy. If you use any of these medications, you must tell us about it.
If your medication usage changes after the preoperative examination, please let us know. The pharmacy assistant will then note this change in your file.

Conversation with the anaesthetist

The anaesthetist will administer anaesthesia during the operation and monitor your body's functions such as your heart rate, blood pressure and breathing. The anaesthetist will also ensure that you are not in pain.
You will discuss your health with the anaesthetist. He/she will also check whether special measures are required during your operation and which medication you can and cannot use around the time of the operation. The anaesthetist will also explain the type of anaesthesia used during the operation. You can find the brochure containing the type of anaesthesia that you and the anaesthetist have agreed on in MijnIsala. The brochure will also contain information about eating and drinking before the operation (fasting policy).
The anaesthetist you speak to during the preoperative examination is usually not the same anaesthetist who will be with you on the day of the operation.

Conversation with the nurse

The nurse will discuss the arrangements that have been made concerning the preparation for the operation and aftercare. During the discussion, the nurse will run through a number of questions that are important to the nursing department. The nurse will also discuss your home situation with you. He/she will also tell you whether you will need assistance and, if so, which organisations can arrange this for you.
The nurse can send the checklist with the arrangements about the preparation for the operation and aftercare to you by e-mail.
