Steps to Connected Healthcare Cheat Sheet (DRAFT) by [deleted]

Steps to Connected Healthcare

This is a draft cheat sheet. It is a work in progress and is not finished yet.


As the reliance on healthcare data grows, the inter-­con­nec­tivity and regulatory governance of these devices plays a vital role in patient monito­ring, clinical decision support, and care.

The following are solutions to four challenges medical device original equipment manufa­cturers (OEMs) will face as they prepare for the future of connected care.

1. Accurate timing

As primitive at it may seem, the biggest debate today in the medical world is: What is the correct time? Is it the time on the wall clock, the time on the device, or the time on the doctor’s watch? Timest­amping measured data is crucial, as caregivers working across devices need to know what type of care was given to a patient and exactly when. To meet that need, caregivers cannot go by a nurse’s recording of time from a wall clock. Devices must recognize the Network Time Protocal (NTP) of outside devices and synchr­onize device time to server time. Designers should never assume the internal clock on their device will be the only source of time.

2. Eliminate user actions

The less time a caregiver spends manually using or entering data into a device the better. Avoiding propri­etary workflow issues can eliminate the probab­ility of human error. Devices should be designed to perform data exchanges as indepe­ndently as possible without the need for user interv­ention. Designers also need to recognize and understand the broader setting where a device will be used.
For example, the requir­ements of a device in a cardiac care center can vary from the requir­ements of the same device in an orthopedic setting. Research and develo­pment teams that connect medical device OEMs with usability experts and clinicians can improve workflow.

3. Secure pairing

Technology such as Bluetooth can present challenges in pairing and un-pairing devices, potent­ially causing data loss and unsecure commun­ica­tion. Designers must understand pairing needs of individual devices. Arbitr­arily pairing devices could expose patients to non-st­and­ardized inform­ation. If a nurse wants to send a prescr­iption to an infusion device, the infusion device and the device sending the prescr­iption need to have a perfect handshake so the source can be authen­tic­ated. This could prevent a nurse from accide­ntally delivering a prescr­iption to the wrong device. Medical device OEMs need to adopt secure public and private key encryption mechanisms and institute design and audit processes that frequently monitor data loss.

4. Managing compliance

Health Insurance Portab­ility and Accoun­tab­ility Act (HIPPA) compliance is an area of concern for medical device manufa­ctu­rers. As more and more technology manufa­cturers embrace open source techno­logies and commercial libraries available for data encryp­tion, it is important to understand how those techno­logies will impact HIPPA compli­ance. Medical device designers must understand the trail of data that could potent­ially be left on another device and should conduct access­ibility testing of open source packages to ensure they are securing patient records and data to meet HIPPA requir­ements.
