Infection Control and Saudi MOH Regulations Flashcards

A nurse in a tertiary hospital ICU notices that three healthcare workers developed similar febrile respiratory illness within 48 hours. Per Saudi MOH Infection Prevention and Control (IPC) Manual and mandatory notification requirements, within what timeframe must this potential healthcare-associated cluster be reported to the Regional Health Directorate?

Answer: Within 24 hours of identification

The Saudi MOH IPC guidelines require mandatory notification of potential healthcare-associated outbreak clusters — including ≥2 linked cases among HCWs — to the Regional Health Directorate within 24 hours of identification. Waiting 48–72 hours delays public health response and violates MOH notification obligations. A 6-hour threshold applies to specific notifiable diseases (e.g., confirmed MERS-CoV), not cluster suspicion.

A patient confirmed with MERS-CoV requires urgent bronchoscopy in a Saudi MOH-accredited hospital. Which combination of precautions is MOST correct per Saudi MOH MERS-CoV IPC guidelines for this aerosol-generating procedure (AGP)?

Answer: Airborne + Contact precautions with N95 respirator, gown, gloves, eye protection in a negative-pressure room

Saudi MOH MERS-CoV IPC guidelines mandate Airborne + Contact precautions for ALL MERS-CoV patient care, and during AGPs this is intensified: a fit-tested N95 (or higher), long-sleeved gown, gloves, and eye/face protection must be used in a negative-pressure airborne infection isolation room (AIIR). Positive pressure rooms are contraindicated — they push contaminated air outward. Contact precautions are never dropped during AGPs; they remain mandatory throughout.

Per the Saudi MOH IPC Manual aligned with CBAHI Patient Safety Standards, a sharps container in a clinical area should be sealed and sent for disposal when it reaches which fill level?

Answer: Three-quarters (75%) full

Saudi MOH IPC guidelines and CBAHI standards specify that sharps containers must be sealed and removed from clinical areas when they reach three-quarters (75%) full. Filling beyond this level significantly increases the risk of needlestick injury during closure. Allowing containers to reach 100% capacity violates both MOH healthcare waste regulations and CBAHI accreditation standards, and can result in a non-conformity finding during audit.

During a Clostridioides difficile (C. diff) outbreak on a medical ward in a Saudi hospital, the IPC team recommends environmental decontamination. Which disinfectant and concentration is specifically indicated per Saudi MOH IPC guidelines for terminal cleaning of C. diff-affected rooms?

Answer: Sodium hypochlorite (bleach) at 5,000 ppm (0.5%)

C. difficile produces heat- and alcohol-resistant spores that are NOT eliminated by alcohol-based products or quaternary ammonium compounds. Saudi MOH IPC guidelines, consistent with WHO and CDC guidance, mandate sporicidal agents for C. diff outbreak decontamination — specifically sodium hypochlorite at 5,000 ppm (0.5%) for outbreak/terminal cleaning, compared to 1,000 ppm for routine daily cleaning in confirmed C. diff rooms. Chlorhexidine and quats lack sporicidal activity against C. diff.

A neurosurgical instrument set used on a patient later confirmed to have Creutzfeldt-Jakob disease (CJD) must undergo prion decontamination. Per the Saudi MOH IPC Manual and WHO guidelines adopted by Saudi facilities, which autoclave protocol is required for these instruments?

Answer: Steam sterilization at 134°C for a minimum of 18 minutes

Prions (misfolded proteins causing CJD) are extraordinarily resistant to standard sterilization methods. WHO guidelines — adopted in Saudi MOH IPC manuals for high-risk/prion-contaminated surgical instruments — specify steam sterilization at 134°C for a minimum of 18 minutes in a gravity displacement autoclave (or 18 minutes in a pre-vacuum cycle). Standard 4-minute flash cycles are insufficient. EtO gas and glutaraldehyde do NOT inactivate prions and must never be used as the sole decontamination method for CJD-risk instruments.

A CBAHI accreditation surveyor audits the hand hygiene program of a Saudi MOH-accredited hospital. The surveyor reviews the facility's direct observation compliance data for the past quarter. What is the MINIMUM acceptable hand hygiene compliance rate required by CBAHI Patient Safety Standards to avoid a non-conformity finding?

Answer: 80%

CBAHI Patient Safety Standards set a minimum hand hygiene compliance threshold of 80% based on direct observation audits covering all five WHO moments. Facilities falling below this benchmark receive a non-conformity finding, which must be addressed through a corrective action plan. A 70% rate — while commonly cited as a baseline in older literature — falls below current CBAHI requirements. The 90% threshold is an aspirational goal recommended by MOH IPC leadership but is not the minimum standard required to pass accreditation.
