Collaboration and connection were front-and-center during the six pre-conferences today at to kick off the Annual Educational Conference. The pre-conferences, which are designed to appeal to those across experience levels from a first-year coord Media Coverage. Key Topics. Where recommendations refer to guidance from the American Institute of Architects AIA , the statements reflect standards intended for new construction or renovation. Existing structures and engineered systems are expected to be in continued compliance with those standards in effect at the time of construction or renovation.
Also, in the absence of scientific confirmation, certain infection-control recommendations that cannot be rigorously evaluated are based on strong theoretic rationale and suggestive evidence. Finally, certain recommendations are derived from existing federal regulations. Performance Measurements. Infections caused by the microorganisms described in this guideline are rare events, and the effect of these recommendations on infection rates in a facility may not be readily measurable.
Therefore, the following steps to measure performance are suggested to evaluate these recommendations:. Contributors to this report reviewed primarily English-language manuscripts identified from reference searches using the National Library of Medicine's MEDLINE, bibliographies of published articles, and infection-control textbooks. All the recommendations may not reflect the opinions of all reviewers.

Key Terms. The air in an AII room is preferably exhausted to the outside, but may be recirculated provided that the return air is filtered through a high-efficiency particulate air HEPA filter. The use of personal respiratory protection is also indicated for persons entering these rooms when caring for TB or smallpox patients and for staff who lack immunity to airborne viral diseases e.
Protective environment PE is a specialized patient-care area, usually in a hospital, with a positive air flow relative to the corridor i. Immunocompromised patients are those patients whose immune mechanisms are deficient because of immunologic disorders e. Immunocompromised patients who are identified as high-risk patients have the greatest risk of infection caused by airborne or waterborne microorganisms. Patients in this subset include persons who are severely neutropenic for prolonged periods of time i.
As in previous CDC guidelines, each recommendation is categorized on the basis of existing scientific data, theoretic rationale, applicability, and possible economic effect. The recommendations are evidence-based wherever possible. However, certain recommendations are derived from empiric infection-control or engineering principles, theoretic rationale, or from experience gained from events that cannot be readily studied e.
The HICPAC system for categorizing recommendations has been modified to include a category for engineering standards and actions required by state or federal regulations. These standards reflect a consensus of expert opinions and extensive consultation with agencies of the U.
Department of Health and Human Services. Compliance with these standards is usually voluntary. However, state and federal governments often adopt these standards as regulations. Certain recommendations have two category ratings e. Rating Categories. Category IA. Strongly recommended for implementation and strongly supported by well-designed experimental, clinical, or epidemiologic studies. Category IB. Strongly recommended for implementation and supported by certain experimental, clinical, or epidemiologic studies and a strong theoretic rationale.
Category IC. Required by state or federal regulation, or representing an established association standard. Note: Abbreviations for governing agencies and regulatory citations are listed where appropriate. Recommendations from regulations adopted at state levels are also noted. Recommendations from AIA guidelines cite the appropriate sections of the standards. Category II. Suggested for implementation and supported by suggestive clinical or epidemiologic studies, or a theoretic rationale.

Contact GPO for current prices. Summary The health-care facility environment is rarely implicated in disease transmission, except among patients who are immunocompromised.
Relative to previous CDC guidelines, this report revises multiple sections e. Key recommendations include infection-control impact of ventilation system and water system performance; establishment of a multidisciplinary team to conduct infection-control risk assessment; use of dust-control procedures and barriers during construction, repair, renovation, or demolition; environmental infection-control measures for special areas with patients at high risk; use of airborne-particle sampling to monitor the effectiveness of air filtration and dust-control measures; procedures to prevent airborne contamination in operating rooms when infectious tuberculosis TB patients require surgery; guidance regarding appropriate indications for routine culturing of water as part of a comprehensive control program for legionellae; guidance for recovering from water-system disruptions, water leaks, and natural disasters e.
Performance Measurements Infections caused by the microorganisms described in this guideline are rare events, and the effect of these recommendations on infection rates in a facility may not be readily measurable. Therefore, the following steps to measure performance are suggested to evaluate these recommendations: Document whether infection-control personnel are actively involved in all phases of a health-care facility's demolition, construction, and renovation.
Activities should include performing a risk assessment of the necessary types of construction barriers, and daily monitoring and documenting of the presence of negative airflow within the construction zone or renovation area. Monitor and document daily the negative airflow in AII rooms and positive airflow in PE rooms, especially when patients are in these rooms. Perform assays at least once a month by using standard quantitative methods for endotoxin in water used to reprocess hemodialyzers, and for heterotrophic and mesophilic bacteria in water used to prepare dialysate and for hemodialyzer reprocessing.
Evaluate possible environmental sources e. If environmental contamination is found, eliminate the probable mechanisms. Document policies to identify and respond to water damage. Such policies should result in either repair and drying of wet structural or porous materials within 72 hours, or removal of the wet material if drying is unlikely within 72 hours.
