31.1.04 Contraindications

You can add contraindications to you medications as they are added to your system.  A contraindication is a condition or factor that will create a caution message or prevent the administering of a medication in REACH based on the potential harm that it may cause to a patient. 

Indications is the reason why a patient is prescribed or is taking a medicine whereas  Contraindication is the opposite of an indication, it is a reason why a patient should not take a medicine.

Adding Contraindications when creating medicines

When creating a medication in REACH you can create user defined contraindications that will generate caution alerts or prevention when administering a medication to a student.

Example 1     Panadol will contraindicate with itself if attempting to be administered < 4hrs apart.
Example 2     Paracetamol may contraindicate with some cold & cough mixtures which have Paracetamol as an ingredient.


In medicines there are two types of contraindications:

  • Relative contraindications means that caution should be used when two drugs or procedures are used together. (It is acceptable to do so if the benefits outweigh the risk.)
  • Absolute contraindication means that event or substance could cause a life-threatening situation. A medicine that falls under this category must be avoided. There are many medicines should not be used together by the same person.

.

Contraindication settings

Contraindications are generally a relationship between two medications however you can also use contraindications to manage minimum time intervals between dosages of a single medication.

A Contraindications message is triggered when the Contraindications Rule is triggered.  Relative contraindications can be set to deliver a caution message (soft restriction) whilst Absolute contraindications can be set to prevent a medication from being administered (hard restriction)....
