MediCall | intelligent communication for anesthesiologist
MediCall is a communicational system for anesthesiologist from inside the operation room to outside. It looks for human-computer symbiosis in professional communication.
MediCall is an intelligent communicational system for anesthesiologist from inside the operation room to outside. It looks for human-computer symbiosis in professional communication. It helps to make more efficient and accurate communication with voice recognition, live visualized data and info in advance. It will improve the situation awareness and keep on the same page.

FIELD STUDY & INTERVIEW Why We Choose Communication Problem Area?
“Ineffective team communication is frequently at the root of medical error. They occurred in approximately 30% of team exchanges.”
- Qual Saf Health Care. 2004 Oct;13(5):330-4.
“In the United States and Sweden, anesthesiologist takes care of several patients. It’s because there are a lack of experienced anesthetist.”
- Dilip Pawar, Anesthesiologist
JOURNEY MAP Current Communication Workflow
In Sweden, an anesthesiologist need to take care of several operations at the same time. Anesthesia nurse helps when they are not there. Thus, it mainly come to 4 scenarios in communication from inside the operation room to outside: updating current situation, calling for advice, calling for help and emergency call to everyone.
However, current communication flow has big information delay, information loss and lack of urgency level in orange part.
“The doctors use a personal pager. You really have to remember those numbers. The good thing is that it only has 5 digital numbers. I write them down on my scrubs......If the anesthetist is in an OR, I need to wait him to call back. I also try to formulate as much information as possible in a short of time. ”
-Nils, Anesthesia Nurse
"Today we only have two states, normal and real emergency......it is really annoying when I’m in patient meeting and constantly get interrupted with pagers even though it is not an emergency at all."
- Moayad, Anesthesiologist
MEDICALL Future Communication System For Anesthesiologist In 2032
Why is 4 emergent levels?
4 emergent levels fits well to the needs of 4 main scenarios. From the user testing to anesthesia nurses, yellow level and orange level are quite valuable for their situation awareness and making decisions.
Green and yellow levels are for sending a update or a message that is not that urgent and gives you the choice if you want to call or record a voice message. Orange level is instantly calling the person or department that you choose and red if for emergencies and are sending a message to the anesthesia team that they have to come to the OR right away.
For receiver, the emergency level is indicated by color and by sound, so that the receiver knows if he/she needs to respond right away or can finish the task at hand first.
For caller, he/she can know whether the person is available or not.
There is also a timeline to show the progress of current tasks and which task is going on now.
We started off our research by visiting Academic Hospital in Uppsala and University Hospital in Umeå. Our team observe 9 real operations and talk with anesthetists during the surgery. We also visited our collaborating partner Getinge and learned details about their products.
DEFINING PROBLEM AREAS 4 Problem Areas that We Are Interested In
We mapped out anesthetist's decision points during an operation into flowcharts, and analyze current problems and opportunities. It works well when we put them into the coordinate of positive-negative & UI-UX. After voting for problem areas grouped by HMW questions, we choose 4 problem areas: response to unexpected events, out of control, training (in operation room), and gaining trust (from patient).
CO-CREATION WITH STAKEHOLDERS
We make a research workshop with representatives from Getinge, where we share insights and deeper information of each problem areas. They share personal experience and perspectives with the question of what it is for you, and brainstorm together on what if it is different in the future scenario.
based on scenarios & interaction points
based on physical prototype
based on role playing
The first prototype is based on new work flow for communication which puts all information
in advance. That is, showing emergency level, pre-recording before operation, sending voice message and taking pictures of screen.Through observation, we find that people tend to call when time is limited, and send voice message when they are not urgent. Thus, pre-recording doesn't fit well to the urgent situation, which is a big fail.
The second prototype is based on voice recognition and physical knob. We combine sharing data with talking, also combine emergency levels with calling. We find that people are comfortable with current flow during communication. Therefore, we get more feedback on details about usability, such as whether timeline is understandable or not, etc.
USER TESTING WORKSHOP WITH NURSES
During the presentation to anesthesia nurses, we explored three different parts of the concept,
- the way to communicate the emergency levels
- the way to communicate extra information
- where to place the machine in the operation room and how it will fit in their professional context
“It’s important to be on the same page and agree on the same actions during communication.”
- Ola, Anesthesia Nurse
“Getting the person outside the OR to see the trends (like blood pressure) can be very helpful.“
