The ventilation system shall be inspected and maintained in accordance with the written maintenance schedule to ensure that a properly conditioned air supply meeting minimum filtration, humidity and temperature requirements is provided in critical areas such as the surgical and recovery suites under Chapter 571 (relating to construction standards).

Observations:
Based on review of facility documents, observation, and staff interview (EMP), it was determined the facility failed to ensure the Procedure Rooms/Operating Rooms, PACU and Pre-OP rooms met the humidity level requirements per policy. Findings include:
On February 19, 2026, review of facility policy "Humidity and Temperature Control" with original date of January 18, 2024, revealed "POLICY It is the policy of UPMC Pinnacle hospitals to maintain temperature and humidity within defined parameters in the critical areas to ensure a safe environment and reduce infection control concerns. Rooms that are considered critical, like those where invasive procedures are performed or where sterile items are stored, are to be in constant compliance when being used for their intended purpose. II. PURPOSE The purpose of this policy is to provide guidance regarding the management of humidity and temperature controls in critical areas. Temperature and humidity controls shall be set according to the "Ventilation Requirements for Areas Affecting Patient Care in Hospitals and Outpatient Facilities "as outlined in the Guidelines for Design and Construction of Hospital and Health Care Facilities. PROCEDURE 1. Humidity controls shall be set to maintain relative humidity ranges per FGI/ASHRE guidelines in the critical areas in which invasive procedures are performed or where sterile items are stored. 2. Temperature controls for critical areas shall be set at the level designated by the "Ventilation Requirements for Areas Affecting Patient Care in Hospitals and Outpatient Facilities " guidelines outlined in the Guidelines for Design and Construction of Hospital and Health Care Facilities. a) Surgeons or surgical procedures may require room temperatures, ventilation rates, humidity ranges, and/or air distribution methods that exceed the minimum indicated ranges. 3. The Facilities Maintenance Department performs computerized checks of the temperature and humidity in critical areas daily. The report is made available to the Director of those critical areas or their designee for review. 4. If temperature or humidity go out-of-range and cannot be rectified: a) The Manager of Facilities Maintenance or their designee will notify the Director of those critical areas or their designee. b) The Facilities and Engineering staff member will generate a computerized work order, noting the corrective work performed."
On February 19, 2025, review of the "2008 ANSI/ASHERAE TABLE 7-1 Design Parameters" which is referenced in the facility poloicy revealed "Function of Space - Classes B and C operating rooms ... Recovery room ... Relative Humidity (k), %, 30-60"
On February 19, 2026, review of facility temperature and humidity log manually collected by facility staff for the Gastrointestinal (GI) Procedure room revealed:
On July 2, 2026, the humidity in the procedure room was 74%, and two procedures were performed that day. On July 8, 2026, the humidity was 69%, and six procedures were performed that day. On July 10, 2026, the humidity was 71%, and six procedures were performed that day. On July 11, 2026, the humidity was 72%, and three procedures were performed that day. On July 16, 2026, the humidity was 77%, and one procedure was performed that day. On July 23, 2026, the humidity was 71%, and seven procedures were performed that day. Request for work order sent to Maintenance team for data above. None provided. Request for temperature and humidity monitoring of GI procedure room the months of August to December 15, 2025. None provided. Request for temperature and humidity monitoring of Recovery areas for the months of August to December 15, 2025. None provided. Review of facility computerized "Temperature/Humidity Log" revealed: Operating Room one (1) humidity reading results to be below 30% November 1,2, 4-7, 10,11,16-18, 2025, and November 23, 24, 27-30, 2025; December 1-17, 20, 21 2025, with readings dropping as low as 12%.
Review of facility computerized "Temperature/Humidity Log" revealed: Operating Room two (2) humidity reading results to be below 30% November 1, 4-7, 10,11,18, 2025, and November 27-30, 2025; December 1, 3-17, 20, 21,2025, with readings dropping as low as 16%.
Review of facility computerized "Temperature/Humidity Log" revealed: Operating Room three (3) humidity reading results to be below 30% November 1-7, 10,11,14-25, 2025, and November 27-30, 2025; December 1-17, 20, 21 2025, with readings dropping as low as 4%.
Review of facility computerized "Temperature/Humidity Log" revealed: Operating Room five (5) humidity reading results to be below 30% November 11,18, 27-29, 2025; December 1,3-9, 11-17, 20,21, 2025, with readings dropping as low as 10%.
Request for safety checks performed on dates humidity was out of range, physician notation to proceed with procedures while humidity levels were out of range none was provided.
Interview with EMP1 on February 19, 2026, EMP1 confirmed procedures with the use of electrocautery were performed on the above dates noted where humidity levels were below range. EMP1 also confirmed the issue has been in effect for the year 2025 and the facility is seeking to replace the HVAC system.
| | Plan of Correction - To be completed: 05/12/2026
The organization has approved the design and replacement of the HVAC system and additional electronic building automated system at the ASF. In the meantime, to address any out-of-range humidity readings, the following process is followed: Alert parameters are set in the electronic building automated system to ensure prompt direct notification of the facilities department staff members of any out-of-range humidity conditions. A daily humidity report is generated and sent electronically to key stakeholders. Using the algorithm contained within the policy, Humidity and Temperature Control, the appropriate staff members will take the defined action steps in response to out-of-range values. Any corrective actions taken by Facilities in response to the alerts will be documented in the electronic work order system. If the relative humidity remains out of compliance, the Medical Director or designee will review the values and make the determination if it is safe to proceed with cases. This review will be documented on an attestation form. The ASF Administrator or designee will audit compliance with following the relative humidity out-of-range action steps. Audits will be reviewed during the ASF Quality meetings.
