Between 2020 and 2022, Massachusetts healthcare facilities rebuilt their cleaning programs under pressure. Some of those changes were genuinely better practice and deserve to stay. Others were reassurance theatre that cost money without reducing risk. Now that the emergency rules are gone, practice managers and administrators have a chance to keep the first group and retire the second. This guide separates the two, with the evidence behind each call.
What Changed — and What the Science Later Showed
Early in the pandemic, surfaces were treated as a primary route of transmission, and many facilities responded with constant disinfection, fogging and closed waiting rooms. As evidence accumulated, the picture shifted. In April 2021, CDC published a science brief concluding that the risk of SARS-CoV-2 infection from touching contaminated surfaces is generally low — each contact carrying less than a 1 in 10,000 chance of infection in its modelling — and that the virus spreads mainly through respiratory droplets and aerosols.
That finding did not make surface cleaning pointless. It meant surface cleaning should go back to what it was always for: controlling the organisms that do spread by contact in healthcare — C. difficile, MRSA, VRE, norovirus and others — while air and respiratory measures handle respiratory viruses. The five changes below are the ones worth keeping for exactly that reason.
Change #1 to Keep: A Real High-Touch Surface Program
Before 2020, many outpatient offices cleaned "the room" once a day. The pandemic forced facilities to list their high-touch points — check-in counters, pens, payment terminals, door levers, chair arms, light switches — and clean them on a defined schedule. That discipline is worth keeping because contact-spread organisms survive on those same surfaces for days to months.
- Keep a written inventory of high-touch surfaces for each area.
- Keep between-patient cleaning of the patient zone in exam rooms, procedure rooms and dialysis stations.
- Scale back pandemic-era hourly wiping of low-risk areas such as staff offices if your risk assessment no longer supports it.
Our guide to high-touch surface disinfection frequency sets out risk-based schedules by facility type.
Change #2 to Keep: Contact-Time Discipline
COVID-19 made staff read disinfectant labels for the first time. EPA's List N pushed facilities to check that a product was registered for the target pathogen and to respect its contact time — the period a surface must stay wet to achieve the label's kill claim. That habit is the single most valuable legacy of the pandemic.
The lasting lesson is not "use a List N product". It is: match the label's claims to the organisms you actually face, and keep the surface wet for the full contact time. A sporicidal claim matters for C. difficile; a norovirus claim matters in long-term care; a one-minute contact time is practical for between-patient wipes. See our EPA-registered disinfectants guide for product selection.
Change #3 to Keep: Ventilation as Part of Infection Control
The largest real gain from the pandemic was treating air as part of the clean environment. In 2023 CDC published a ventilation target of at least five air changes per hour of clean air for occupied spaces, and ASHRAE issued Standard 241, Control of Infectious Aerosols, with equivalent-clean-airflow targets for different space types.
Ventilation is the building's responsibility rather than the cleaning contractor's, but environmental services teams play a supporting part that is easy to lose:
- Keep portable HEPA units' intakes and outlets clear, and follow the manufacturer's filter-change schedule.
- Clean supply and return grilles on a documented schedule; dust-laden grilles reduce airflow.
- Report blocked vents, propped-open doors that defeat pressure relationships, and units that have been switched off.
Change #4 to Keep: Documentation You Can Show a Surveyor
During the pandemic, many offices started keeping cleaning logs for the first time because staff and patients wanted proof. Keep them. Massachusetts Department of Public Health licensure rules for clinics (105 CMR 140.000) and long-term care facilities (105 CMR 150.000) expect written infection control and housekeeping practices, and a log of who cleaned what, when and with which product is the evidence that those practices are followed.
- A cleaning schedule by area, with frequency, product and responsible role;
- Completion logs initialled by the person who did the work;
- Monitoring results — fluorescent marking, ATP testing or direct observation;
- Safety Data Sheets, EPA registration numbers and staff training records.
Change #5 to Keep: Outbreak Playbooks
Facilities that handled COVID-19 well had a pre-agreed escalation plan: who decides to step up cleaning, which products change, which rooms get terminal cleaning, and how the cleaning contractor is notified. That same playbook works for norovirus in long-term care, influenza surges, C. difficile clusters and measles exposures.
Write it down once, with triggers ("two or more linked cases", "resident on contact precautions"), product changes, frequency changes and a named contact at your cleaning vendor. Review it once a year.
What to Retire
Some pandemic practices add cost without adding protection and can safely be dropped or scaled back:
- Routine fogging or electrostatic spraying as a substitute for wiping. Spraying does not remove soil and cannot reach the same dwell times reliably on every surface. It can supplement manual cleaning; it should not replace it.
- "Deep cleans" after every positive COVID-19 case in outpatient areas. Standard cleaning and disinfection of the patient zone with an appropriate product is what current guidance supports.
- Blanket hourly disinfection of every surface. Replace it with a risk-based high-touch schedule.
- Plexiglass everywhere. Many barriers now collect dust, obstruct airflow and are rarely cleaned. Keep only those with a current purpose and add them to the cleaning schedule.
- Unregistered or improvised products. Anything without an EPA registration number and a clear label should be removed.
Regulatory Status in 2026
The federal emergency framework is over. OSHA withdrew the non-recordkeeping portions of its COVID-19 Healthcare Emergency Temporary Standard in December 2021, and the federal public health emergency ended in May 2023. What remains in force are the permanent standards that applied before the pandemic — OSHA Bloodborne Pathogens (29 CFR 1910.1030), the Hazard Communication Standard for chemicals, state licensure rules — plus CDC's infection control recommendations. Your cleaning program should be built on those, not on memories of 2020 rules.
A 30-Minute Review for Your Facility
- List the pandemic-era cleaning practices still in place.
- For each, write down the organism or risk it controls today. If you cannot name one, it is a candidate to retire.
- Check every disinfectant label for claims and contact time, and confirm staff are following them.
- Confirm your high-touch inventory, schedule and logs are current.
- Confirm your outbreak playbook names a contact at your cleaning vendor.
Frequently Asked Questions
Do we still need to use EPA List N disinfectants?
List N was built for SARS-CoV-2. What matters now is that your products are EPA-registered hospital disinfectants with claims against the organisms relevant to your facility, used at the full label contact time.
Is electrostatic spraying worth keeping?
It can be a useful supplement for large or complex spaces, but it does not replace manual cleaning of high-touch surfaces. If you keep it, document the product, contact time and areas covered.
Should waiting rooms still be cleaned more often than before 2020?
The high-touch points in waiting rooms — counters, pens, payment terminals, chair arms and door handles — are shared by every patient, so a defined multiple-times-daily schedule during clinic hours remains good practice for contact-spread organisms.
