Software updates, or patches, fix security flaws that attackers actively exploit. Many well-known breaches began with a vulnerability for which a patch had already been available. For busy clinics and care facilities, though, patching creates real tension. Computers cannot restart during medication passes, an EMR update might break an interface and nobody wants a surprise after-hours call.
The answer is a predictable schedule with a fast lane for emergencies. Here is how to build one.
Think beyond Windows updates.
Operating systems on servers and workstations
Applications such as web browsers, PDF readers, office suites and remote support tools
Firewalls, VPN appliances, switches and wireless access points
Hypervisors and storage systems
Printers and copiers
Line-of-business applications, including the EMR client and interfaces
Medical and connected devices, which often follow manufacturer-controlled update processes
Edge devices, especially VPN appliances and firewalls, deserve priority because they face the internet and are frequently targeted.
You cannot patch what you do not know exists. Maintain an inventory of devices, operating systems and software versions. Remote monitoring tools can report this automatically and show which systems are missing updates.
Not every patch is equally urgent. A simple triage approach:
Emergency: Vulnerabilities known to be exploited in the wild, or flaws in internet-facing systems. The CISA Known Exploited Vulnerabilities catalog is a useful public reference. Target deployment within days, sometimes sooner.
High: Critical or high-severity vulnerabilities on systems that handle PHI. Target within roughly two weeks.
Routine: Regular monthly updates and lower-severity fixes. Target within roughly thirty days.
Your own targets may differ, but write them down and track compliance.
Many organizations align with the vendors' regular release cycles.
Week one: Updates are released and reviewed. IT identifies anything notable.
Week two: Deploy to a small pilot group, such as IT's own machines and a few volunteer users, and watch for problems.
Weeks three and four: Roll out to the rest in waves, scheduled during low-activity windows.
Following week: Verify, report on exceptions and handle stragglers.
Schedule workstation restarts during shift changes, overnight or on weekends where possible
Allow staff to postpone restarts briefly, but enforce a deadline
Coordinate server maintenance with clinical leadership, and communicate in advance
Avoid patching all units at once, so that a problem does not hit everyone together
For 24-hour operations, rotating windows by unit and having a rollback plan reduces risk.
Test critical updates on a few representative machines before broad rollout
Take backups or snapshots of servers before major changes
Know how to uninstall an update that causes trouble
Confirm with your EMR vendor which operating system and browser updates are compatible
Some systems cannot be updated immediately: devices awaiting vendor approval, legacy software or a machine with a fragile dependency. For these:
Document the reason and the planned date
Isolate the system on a restricted network segment
Add compensating controls such as monitoring, limited access and application allow-listing
Ask the vendor for security guidance and an upgrade path
Never leave the exception undocumented. Accepted risk with an owner and review date is defensible, while forgotten risk is not.
Useful numbers for leadership include:
Percentage of devices fully patched within target windows
Number of emergency patches and time to deploy
Count of systems running unsupported software
Outstanding exceptions and their age
A one-page monthly summary keeps patching visible. It also supports your HIPAA risk management documentation.
Relying on staff to install updates themselves
Ignoring third-party applications while updating the operating system
Never rebooting, so updates are downloaded but not applied
Patching servers but forgetting firewalls and network devices
Failing to confirm that patches actually installed
The clinics that do this well treat patching like medication rounds: scheduled, documented and checked. Start with a simple calendar and an inventory, then improve it over time.
UnityCare IT provides managed patching for healthcare organizations, including scheduling around clinical operations, emergency response to critical vulnerabilities and clear reporting. If updates are inconsistent at your facility, we can help you bring order to it.
