TABLE 1
HISTORY OF PRECAUTIONS Year Document Issued Description
1970 Isolation Technique in Hospitals CDC published- Guide for Hospitals
1975
Manual revised
Introduced seven isolation precaution categories with color-coded cards : Strict , Respiratory , Protective , Enteric , Wound and Skin , Discharge , and Blood : No user decision-making required . Simplicity a strength ; over isolation prescribed for some infections
1983 CDC Guidelines for Hosp . Isolation replaced previous manual
Provided two systems for isolation : category-specific and disease-specific - Protective Isolation eliminated ; Blood Precautions expanded to include Body Fluids - Categories included Strict , Contact , Respiratory , AFB , Enteric , Drainage / Secretion , Blood and Body Fluids . Emphasized decision-making by users
1985-1988
Universal Precautions
Developed in response to HIV / AIDS epidemic . Dictated application of Blood and Body Fluid precautions to all patients , regardless of infection status . Did not apply to feces , nasal secretions , sputum , sweat , tears , urine , or vomitus unless contaminated by visible blood . - Added personal protective equipment to protect health care workers from mucous membrane exposures . Handwashing recommended immediately after glove removal . Added specific recommendations for handling needles and other sharp devices ; concept became integral to OSHA ’ s 1991 rule on occupational exposure to bloodborne pathogens in healthcare settings
1987
Body Substance Isolation
BSI focused on the isolation of all moist and potentially infectious body substances from all patients , regardless of their presumed infection status , primarily through the use of gloves . The airborne route of transmission was introduced and nurses would determine use of masks . Shared some features with Universal Precautions . Weak on infections transmitted by large droplets or by contact with dry surfaces . Did not emphasize need for special ventilation to contain airborne infections . Handwashing after glove removal not specified in the absence of visible soiling
Early 1990 ’ s
Standard Precautions
As a result of confusion related to UP and BSI , isolation practices were overhauled and an “ enhanced ” set of precautions called standard precautions , were designed to reduce the risk of transmission of bloodborne and other pathogens in hospitals . In conjunction with standard precautions , transmission-based precautions were introduced to reduce the risk of airborne , droplet , and contact transmission in hospitals .
1991 OSHA Bloodborne Pathogen Rule Focus on protecting healthcare workers
1996 Guideline for Isolation Precautions in Hospitals
2007 Guideline for Isolation Precautions : Preventing Transmission of Infectious Agents in Healthcare Settings ( 2007 )
2012 & updated in 2016
“ Guide to Infection Prevention for Outpatient Settings : Minimum Expectations For Safe Care ”
Prepared by the Healthcare Infection Control Practices Advisory Committee ( HICPAC ). Melded major features of Universal Precautions and Body Substance Isolation into Standard Precautions to be used with all patients at all times . Included three transmission-based precaution categories : airborne , droplet , and contact . Listed clinical syndromes that should dictate use of empiric isolation until an etiological diagnosis is established
Updates and expands the 1996 Guideline for Isolation Precautions in Hospitals . Reasons for updates : Transition of healthcare delivery from hospitals toother healthcare settings ; Nosocomial infections became healthcare-associated infections ( HAIs ); emergence of new pathogens ; Standard Precautions expanded to include respiratory hygiene / cough etiquette and safe injection practices ; Increased focus on environmental controls and protective environment ; administrative involvement in development and support of Infection control programs ; Increased HAIs and MDROs
It includes a comprehensive list of practices including hand hygiene , PPE , injection safety ( if applicable ), respiratory hygiene / cough etiquette , point-of-care testing ( if applicable ) and environmental cleaning . In addition , device reprocessing is also addressed as many outpatient facilities including surgery centers , are providing services that include the need to reprocess reusable patient care items .
2019
Enhanced Barrier Precautions
“ Require gown and glove use for certain residents during specific high-contact
resident care activities that have been found to increase risk for MDRO transmission ,”
according to the CDC .
2020-2021 Temporary revisions based on COVID -19 Extended use of PPE , use of facemasks and gowns which were in poor supply
