Modelling the Social Practices of an Emergency Room to Ensure Staff and Patient Wellbeing

My doctor didn’t look at me during my last visit

2

The emergency room suffers from social problems

3

Patients and staff take up more time, become unsatisfied and counterproductive.

4

Patient and Staff are healthier, cooperative and are more satisfied

5

The emergency room suffers from social problems… how to keep track of this complex system?

6

Our formal model of the social ER can help management in finding social problems

Modelling the ER is split in three task: a meta- model, model and modelling desirable social properties

Our model aims to capture the social dimension by using the concept of social practices

ER UML 1

The Social Practice Agent (SoPrA) meta- model focuses on activities as the core of a social system

10

ER UML 1

The social practice of acute treatment is captured in an activity tree

11

ER UML 1

12

SoPrA models associations with these activities such as human values

SoPrA models associations with these activities such as human values

ER UML 1

One might associate the value of security and health to contact an ER

15

ER UML 1

Agents belief certain activities

16

ER UML 1

Patient1 beliefs (one view one) contact_ER

17

ER UML 1

Doctor beliefs a different view on contact_ER

18

ER UML 1

Agent differ in what human values they adhere to

19

ER UML 1

A patient adheres to the value security and health

Modelling the ER is split in three task: a meta- model, model and modelling desirable social properties

Based on empirical observations we formulated social properties management could desire

• The staff understand the needs of the pa0ents.
• A head nurse can cover some of the necessary tasks of the secretary.
• The staff can help each other out, because they know the equipment

the others need.

22

ER UML 1

The desirable properties are modelled in terms of the SoPrA meta-model

23

The staff understand the needs of the paSents. The staff and paSents belief the same perspecSve on an acSvity, for all acSviSes which promote values that the paSent has

We can express possible models that satisfy this property

24

To be able to make inferences we formalize the model in OWL

By using OWL we can state rules about the relation of concepts: e.g. the inheritance of values

Modelling the social properties in SPARQL-queries

SELECT ?agent ?value ?acSvity WHERE { ?agent a:belief ?acSvity. a:PaSent a:HasValue ?value. ?acSvity a:promotedValue ?value} The staff and paSents belief the same perspecSve on an acSvity, for all acSviSes which promote values that the paSent has

Using SPARQL you can query the database and get back a table of possible instances that satisfy the query

Using the result we infer that the desirable social property is not satisfied in this case

The resulting findings can be used as a hypotheses on where to direct intention of management to solve social problems in the ER

Future Work

• To cross-validate our model we need to ground both the model as

well as check the resulSng conclusions against empirical data

• We focused on a rough empirical grounding from observaSons on the

ER at Herlev Hospital Denmark, extend this by more rigorous emprical work

• Process Mining
• Protocols
• Interviews

35

SoPrA differs from other social agent frameworks by capturing the social dimension in shared action assocations
