Transcript of The Human-Technology Interface

What is the "


When humans use a technology, the hardware or software that enables and supports the interaction is the "interface."

Book's Example:


Light Switch

Applied in Medicine:


Charting System


Problems with Human-Technology interfaces.
Technology interfaces being used do not fit well with human characteristics.
Complexeties of user interface may require too many steps and result in errors or confusion.
Users create workarounds. (Patient Bracelets)
Change of workflow with CPOE in Children's hospital in Pittsburgh ED increased mortality rate among children brought into the ED. System developed for Medsurg, but used in ED
Poor Implementation
Human Technology Interface problems are the major cause of as many as 87% of all patient incidents! The technology may preform perfectly in many of these situations, but the interface design may lead to the human user making errors.
Other considerations in Human-Technology Interface and Interaction
It is important to consider variations in interaction for different types of users based on age, vocation, and experience. This holds a greater meaning when cosidering the health care setting where users are of a wide range of age, experience, and have multiple types of jobs.
My ideas for Human-Technology Interface improvements.
1. Tablet Call Light
2. Smart watch integration when recieving
and answering call lights.
3. Nursing Tablets for medication
administration with smaller medication carts.
4. The use of WIFI in IV pumps and
other machines to automatically chart
I/O's and other information.
5. More Patient/Family involvement in Human-Technology
Interface (when possible).

Book Questions:

1. You are the member of a team that has been asked to evaluate a prototype personal digital assistant-based application for calculating drug dosages. Based on what you know about usability testing, which kind of test (or tests) might you do and why?

2. Is there a human-technology interface that you have encountered that you think needs improvement? If you were to design a replacement, which analysis techniques would you choose? Why?

3. Which type of functionality and interoperability would you want from your smartphone, watch, clothing, glasses, camera, and monitor?

Student Ideas for improvements of the human-technology interface:

1. For Nurse clinical use.
2. For ease of Hospital data gathering.
3. For the patient's room.
4. For the improvement of the Nursing and Patient relationship/Patient compliance.
5. For the Patient's ability to be more involved in their healthcare plan.
Smart Watch Interface possibilities in Healthcare.
The 3 Axioms for effective Human-Computer Interactions
1. Users Must Be an Early and Continuous Focus During Interface Design.
(User achieves goal with "Minimal effort and Maximal efficiency")
2. The Design Process Should Be Iterative, Allowing for Evaluation and Correction of Identified Problems.
3. Formal Evaluation Should Take Place Using Rigorous Experimental or Qualitative Methods.
Hospital Social Networking:
Upon admission the Patient or Patient's family will create a non identifying hospital ID/username for the patient. Patients will then be given the opportunity to socialize in a therapy centered chat room with other patients across the country with the same diagnosis. Sessions will be scheduled, limited to small sizes in each chat room, will be monitored by moderators, and will give patients the opportunity to learn more about managing their illness from patients that have experience with the disease process. Family will be able to use this as a form of outreach to help cope with hospice situations, dementia support, LTC placement decisions, etc...
This app will provide education material chosen by the nurse for each specific patient. The material will be short, and sometimes interactive. Each education material will be less than five minutes and will be automatically charted as patient or family education when completed by patient or family member. Learners will chart their own understanding of education and follow up is required by nurse to answer questions and ensure understanding. Core Measure education will be completed by nurse and patient together and signed off by both the nurse and patient. When signed off this too will be automatically charted as patient education.
The Patient Profile app will allow patients to create their own profile within the hospital's patient database. The information included will be work history (exposure to dangerous conditions), favorite hobbies, foods, music, vacation spots, etc... The Patient Profile will also include a small autobiography section that will allow patients to give a brief history of themselves. The information in this app will be available to only the healthcare workers caring for the patient. The patient can update, or edit information with each hospital visit.
The Nursing Care Plan app will allow patients to be more involved in completing care plan goals. When nurses assign care plans to the patient, the patient will be given daily goals to meet each nursing diagnosis care plan. The patient will also be educated on the rationale for these goals, and the benefit completing goals will have on their disease process. If patient is involved in the care plan, and completes rational education this too will be charted as successful patient education.
This app will allow patients to view their home medication list and send a discrepancy notification to the nurse if the list is incorrect. Patients will also be able to review their medication regimen during hospitalization. Discrepancy notifications will be saved and sent to the Nurse at the beginning each shift.
This app will allow patients to review and update their medical history, and family medical history. Updates to history will be alerted to the nurse, once nurse has reviewed he/she will send alert to MD for notification/verification. Only one update will be allowed by the patient in a 24 hour period.
Patients will be able to view radiology, cardiology, etc... reports using this app. A separate patient report will be prepared by radiology, cardiology, etc... using layman's terms and a third grade reading level. After reports are reviewed and discussed with the patient by the physician, the physician will approve the release of the layman's termed report for patient viewing and access. Patient reports will not contain prognosis or treatment options unless added by patient's physician.
Patients will have access to

their weekly schedule with any procedure days/times that are available. If times are not available the day will be marked with the procedure(s) name. All times will be subject to change, but will give a better window of procedure times. The schedule will also include the physician's anticipated discharge day. If PCP and consulting physicians anticipate different dates, the later date will be the date marked.
This app will allow patients to review their plan of care from their PCP as well as the consulting physicians. In this app Patients will have the opportunity to highlight words or phrases that they wish to discuss further with the doctor on their next rounding visit.
This app allows patients to view their lab results once the PCP has released access to the patient.
Some patients and family members prefer autonomy during their hospital stay. This app allows patients or family to chart their own intake and output. The patient or family will be required to demonstrate an understanding of measurements for both input and output before this application can be unlocked by the nurse. If application is not utilized correctly patients will lose access to application. IV pump intake and catheter, chest tube, etc... output will still be the responsibility of nursing staff.
The camera is only accessable to nursing staff, and is intended for the use of wound documentation and the progression of wound(s) throughout a hospital stay. Pictures taken are automatically stored in the patient chart with time stamp and wound description created by nurse.
Using this application, patients will be able to play popular tablet games under their non-identifying hospital
ID/username. Daily contests will be held for patients in the hospital and winners will recieve small prizes(T-Shirts, coffee cups, gift cards, etc...)(Free advertising). Using this app may also assist in distraction from pain, anxiety, or other stressors.
This will share additional hospital applications with patients, as well as allow feedback from patients regarding applications used. Patients will also be able to give suggestions for new apps to improve hospialization experiences.
Patients or family members will have the opportunity to browse the internet for their own interests, Internet will be secure and block inappropriate content.
This application will work as a remote control for the television, as well as a channel guide. Guide will allow patients to set reminders for their favorite shows.
This application will display the weekly meal options with patient specific dietary parameters. Patients will have guidance from the dietician regarding a healthy dietary plan for home.
Book Summary: 3 Main Points from this Chapter
1. The designs for Human-Technology Interface must be radically
improved so that technology better fits human and task requirements.
2. Tools exist for evaluating, analyzing, and design of interface development. They
should be used by designers to ensure optimal user interaction.
3. Using these tools has improved patient safety drastically in some areas, and
these tools applied in other healthcare settings will likely produce the same
