Cleaning and Disinfection SOP for a Pharmacy Sterile Compounding Room: Log Requirements
A sterile compounding room is judged less by how it looks at the start of a shift than by whether the surfaces inside and around the hood were still wet for the full contact time of the agent the SOP names. The pharmacy's cleaning and disinfection programme is written to make that checkable, and the log is the evidence that it happened.
Two layers frame the work. USP General Chapter 797 sets the cleaning and disinfection programme for sterile compounding areas and is the reference most Canadian compounding operations benchmark against, and provincial infection prevention and control guidance sets out how cleaning, disinfection and documentation are expected to work in a health care setting. Because the chapter text sits behind a subscription, the agent list, dilutions and contact times in a SOP should be verified against the current chapter and the product labels rather than copied from a template.
What has to be in the SOP?
An SOP that survives an inspection names the areas and their classification, the agent for each, the dilution, the contact time, the sequence of work, the tools and the frequency, and it says who signs for it.
| SOP section | What it states | What makes it auditable |
|---|---|---|
| Areas and order | hood, immediate work area, buffer area, floors, walls; clean to dirty | a floor plan with each area named |
| Agent and dilution | product name, identification number, dilution in use | the label and the dilution record, not a generic entry |
| Contact time | the wet time required for that agent | the task list showing dwell and the wipe or mop technique |
| Tools | low-linting wipes and mops, changed between areas | tool storage and change-out rule in the SOP |
| Frequency | per task, with a rule for visibly soiled surfaces and spills | a schedule by task and shift |
| Records | what is logged and who reviews it | the log itself, plus the audit schedule |
Which tools and consumables does the room need?
The consumables are part of the programme. Pre-cleaning uses disposable dry wipes that are discarded rather than carried from one area to another, and disinfection follows with the agent the SOP names. People entering the compounding area wear non-woven bouffant caps and disposable gowns, and gloves are changed when the task changes rather than when they look soiled. Medication preparation that involves transferring a solution uses a low dead space syringe so the dose drawn matches the dose labelled.
What gets missed most often?
Three things. Contact time first: a surface wiped and left to dry in seconds has been cleaned, not disinfected. Tool reuse second, because a cloth or mop head carried from a floor to a work surface moves contamination rather than removing it. Records third, because a log kept for its own sake records that someone was in the room rather than which agent was used at what strength for how long.

Pharmacies and clinics building a cleaning programme can start from the cleaning and disinfecting collection.

Frequently Asked Questions
What has to be in a sterile compounding room cleaning SOP?
The areas covered and their classification, the agent used for each area, the dilution, the required contact time, the order of cleaning from clean to dirty, the tools used and how they are changed between areas, the frequency for each task, and who signs for it. It also has to say what happens when a surface is visibly soiled or a spill occurs.
Why is contact time the number that gets audited?
Because a disinfectant works on contact with a wet surface. The published definition of contact time is the time the agent has to remain in contact with the surface or device for disinfection to occur, and for most products the surface has to stay wet for that period. A bench wiped and left dry after five seconds has not been disinfected, however good the agent is.
What does the cleaning log have to record?
Date and time, the area cleaned, the agent and its identification number, the dilution used, the contact time applied, the tools and cloths used, the person who performed the task, and any deviation with the corrective action. A log that records only a signature and a tick cannot show that a sporicidal agent was used on the right surface at the right strength.
How often should a compounding area be cleaned?
The programme sets frequencies by area and by risk: work surfaces and the immediate surroundings of the hood more often than floors and walls, with a sporicidal agent used on the schedule the pharmacy's programme defines. Frequency is written into the SOP by task rather than left to judgement, and cleaning is done more often when the area is visibly soiled.
How is the cleaning programme verified?
By periodic audit with feedback and education rather than by the log alone. Environmental cleaning guidance calls for cleaning practices to be monitored and audited, with the results fed back to the people doing the work. In a compounding pharmacy that usually sits alongside the surface and air monitoring the pharmacy already runs.
