Outpatient infection control failures cause preventable morbidity and expose clinics to serious regulatory risk. This checklist covers hand hygiene, instrument sterilisation, waste management, and environmental cleaning.
Why Outpatient Infection Control Is Underrated
Infection control attention in healthcare is disproportionately focused on hospitals — ICUs, operating theatres, CSSD departments. Outpatient clinics, however, see high patient throughput, involve procedures (injections, dressings, minor surgery, dental treatment, endoscopy), and share contact surfaces between dozens of patients daily.
The WHO estimates that a significant proportion of healthcare-associated infections occur in the outpatient setting, most of which are preventable with basic compliance measures.
1. Hand Hygiene
The five WHO "moments" for hand hygiene:
- Before touching a patient.
- Before a clean/aseptic procedure.
- After body fluid exposure risk.
- After touching a patient.
- After touching patient surroundings.
Preferred method: Alcohol-based hand rub (ABHR) for hands that are not visibly soiled (20–30 seconds). Soap and water for visibly soiled hands or when C. difficile is suspected (spores are not killed by alcohol — mechanical removal with soap required).
Infrastructure requirement: ABHR dispensers at the point of care (not just at the sink). In the examination room, one dispenser visible and accessible without leaving the patient zone.
2. Personal Protective Equipment (PPE)
| Procedure |
Minimum PPE | --- |
--- | Standard examination (no contact with blood/body fluids) |
None required | Wound assessment and dressing |
Gloves | Procedure with blood/body fluid splash risk |
Gloves + mask + eye protection | Aerosol-generating procedure (dental drilling, bronchoscopy) |
FFP2/N95 + gloves + gown + eye protection | Known/suspected respiratory infection (TB, COVID, influenza) |
Surgical mask (patient) + FFP2 (clinician) |
Gloves do NOT replace hand hygiene — hands must be cleaned before donning and after removing gloves.
3. Instrument Reprocessing
The Spaulding classification dictates reprocessing level required:
- Critical (penetrates sterile tissue or vasculature — surgical instruments, dental implant drills): sterilisation (autoclaving at 134°C for 3 minutes or 121°C for 15 minutes).
- Semi-critical (contacts mucous membranes or non-intact skin — speculums, laryngoscope blades, dental mirrors): high-level disinfection (glutaraldehyde 2%, hydrogen peroxide 6%, or sterilant if compatible).
- Non-critical (contacts intact skin — BP cuffs, stethoscopes, examination tables): low-to-intermediate level disinfection (70% isopropyl alcohol wipe).
Key failures to avoid:
- Using chemical disinfectant at incorrect dilution or past expiry.
- Skipping cleaning step before disinfection (organic matter inactivates disinfectants).
- Storing autoclaved packs beyond expiry date (check the indicator tape and expiry label).
- Reusing single-use items.
4. Injection Safety
- One needle, one syringe, one time — never reuse or recap with two hands.
- Use needlestick-prevention devices (retractable needles, safety lancets) where available.
- Dispose of sharps immediately into a puncture-resistant, tamper-evident sharps container — never more than 3/4 full.
- Sharps containers should be at the point of use, not across the room.
Needlestick protocol: wash with soap and water, report to clinic manager, document, assess source patient HIV/HepB/HepC status, initiate PEP within 2 hours if high-risk HIV exposure.
5. Environmental Cleaning
- Examination couch: wipe down with 70% alcohol between patients.
- High-touch surfaces (door handles, taps, light switches, keyboard, card terminal): disinfect at least twice daily and after known contamination.
- Floors: mop with a hospital-grade quaternary ammonium compound disinfectant daily. Do not dry-sweep (aerosolises settled particles).
- Blood spill: absorb with paper towel, apply 10,000 ppm hypochlorite (1:10 dilution of bleach), leave 2 minutes, remove, clean with detergent, rinse.
6. Medical Waste Management
| Waste Type |
Container | Disposal |
| Sharps (needles, blades) |
Yellow rigid sharps container | Collection by licensed medical waste contractor |
| Infectious soft waste (blood-contaminated dressings, gloves) |
Yellow bag | Licensed medical waste contractor |
| Cytotoxic waste |
Purple bag | Specialist contractor |
| General clinical waste (non-contaminated) |
Black/grey bag | Municipal collection |
| Pharmaceutical waste (expired medications) |
Blue box/container | Pharmacist return or specialist contractor |
7. Documentation
Maintain a clinic infection control log covering:
- Daily cleaning records (initialled by staff).
- Autoclave cycle records (date, temperature, load, indicator pass/fail).
- PPE stock levels and restocking dates.
- Needlestick incident reports.
- Annual infection control training completion records for all staff.
