The assessment of pain is important both to healthcare professionals and to the patients themselves: for the measurement and documentation of a patient’s general state and for decisions on the dosage of medicines. The pain scales in current use are based either on self-assessment by the patient or on assessment by others for those patients not able to respond to questioning. In most cases doctors and patients are still working with the classical, but less graphically amenable, paper and pencil methods. Some semi-digital assessment methods exist, but they are of such limited usefulness that compliance rates are very low. As a consequence the data is patchy and unreliable.

In order to facilitate data collection and communication between patient and doctor, we have developed the conceptual design for Quiri, an app for mobile devices that measures the patient’s general state. It is particularly appropriate for use by children and young people suffering from chronic pain. (Quiricus and Julitta are the patron saints of the family and of sick children.)

Our focus lay first on the assessment of pain in children, as this user group poses a particular challenge to the UI.  In the basic conceptual design scalability for other age groups was taken into account. Quiri makes it possible to assess and document pain using a number of different measuring methods and to represent these in an easy-to-use workflow with a contemporary design.

Quiri was developed on the basis of the usability standard for medical equipment IEC 62366. Recently the summative UI validation according to IEC 62366 was prepared for tablet computers with the aid of high fidelity prototypes.

The new designs, for example the one for the faces pain scale developed for children from different ethnic groups, still need to be clinically tested in compliance with the usual test criteria with questionnaires to validate their usability. As before, medical professionals will be consulted.

The range of functions for the final app is still to be decided on (and any new components will be validated where necessary). For example, the requirements analysis has shown that doctors are not only interested in the reliable measurement of the patient’s general state and their current pain experience, but also find a medication data base with information on the planning of medication useful. This can be used to prevent adverse cumulative effects of medications taken in conjunction with other medications.

Our team at Ergosign would be pleased to hear from anyone interested in the implementation of Quiri as an app for use in everyday clinical settings to improve patients’ quality of life.
