Protecting health care workers from SARS and other respiratory pathogens: a review of the infection control literature.

Background Severe Acute Respiratory Syndrome (SARS) was responsible for outbreaks in Canada, China, Hong Kong, Vietnam, and Singapore. SARS focused attention on the adequacy of and compliance with infection control practices in preventing airborne and droplet-spread transmission of infectious agents. Methods This paper presents a review of the current scientific knowledge with respect to the efficacy of personal protective equipment in preventing the transmission of respiratory infections. The effectiveness of infection control polices and procedures used in clinical practice is examined. Results Literature searches were conducted in several databases for articles published in the last 15 years that related to infection control practices, occupational health and safety issues, environmental factors, and other issues of importance in protecting workers against respiratory infections in health care settings. Conclusion Failure to implement appropriate barrier precautions is responsible for most nosocomial transmissions. However, the possibility of a gradation of infectious particles generated by aerosolizing procedures suggests that traditional droplet transmission prevention measures may be inadequate in some settings. Further research is needed in this area.

Protecting health care workers from SARS and other respiratory pathogens: Organizational and individual factors that affect adherence to infection control guidelines

Background Traditional infection control policies have focused on engineering controls, specific protocols, and personal protective equipment (PPE). In light of the variable success in protecting health care workers (HCWs) from Severe Acute Respiratory Syndrome (SARS) in 2003, organizational and individual factors related to self-protective behavior in health care settings may also play an important role. Methods A critical review of the literature was conducted, directed at understanding what organizational and individual factors are important in protecting HCWs from infectious diseases at work. Results Organizational factors, such as a positive safety climate, have been associated with increased HCW adherence to universal precautions. There is some evidence that appropriate training of HCWs could be effective in changing HCW behavior if appropriate follow-up is applied. Very little research into these factors has been conducted with regard to preventing exposures to respiratory tract pathogens, but there was evidence from the SARS outbreaks that training programs and the availability of adequate PPE were associated with a decrease risk of infection. Conclusion Variations in organizational and individual factors can explain much of the variations in self-protective behavior in health care settings. It is likely that these factors were also important determinants during the SARS outbreaks, but they have not been extensively studied.

Personal protective equipment in health care: can online infection control courses transfer knowledge and improve proper selection and use?

We used observational evaluation to assess the ability of an online learning course to effectively transfer knowledge on personal protective equipment (PPE) selection and removal. During orientations for new hospital staff, 117 participants applied either airborne, droplet, or contact precautions in mock scenarios. Postcourse, all 3 scenarios demonstrated improvement in PPE sequence scores (P = .001); moreover, hand hygiene also was more frequent during both donning and doffing of PPE (P < .001).

Impact of a mandated provincial hand hygiene program: Messages from the field

BACKGROUND The British Columbia Provincial Hand Hygiene Working Group was formed in September 2010 and tasked with the development and implementation of a provincial hand hygiene (HH) program for health care. METHODS As part of an evaluation of the provincial HH program, qualitative key informant interviews of program developers, senior administrators, and field workers were performed from December 2011 to March 2012 (phase 1) and again in April to June 2013 (phase 2). RESULTS The following 5 broad themes were identified: (1) the provincial HH program became a platform for cooperation; (2) standardization (of HH audits and program components) strengthened and provided credibility to the provincial HH program; (3) quality results and good communication enabled a learning process that resulted in positive change management; (4) with ownership came pride and program success; and (5) management support and infrastructure is needed to sustain a positive culture change. CONCLUSION Positive behavior change for HH can be achieved on a provincial scale through a program that is standardized, has mandated components, is well communicated, owned by the frontline workers, and receives sustained support from senior management.

Identifying the gaps in infection prevention and control resources for long-term care facilities in British Columbia

BACKGROUND Infection prevention and control (IPC) is a critical, although often neglected, part of long-term care (LTC) management. Little is known about what IPC resources are available for LTC and how that impacts patient care and safety. METHODS One hundred eighty-eight LTC facilities were randomly selected out of all British Columbia facilities and surveyed using a validated survey tool. The tool was used to collect data regarding IPC resources grouped within 6 indices: (1) leadership, (2) infection control professionals (ICP) coverage, (3) policies and procedures, (4) support through partnerships, (5) surveillance, and (6) control activities. All components measured have been identified as key for an effective IPC program. Survey responses were used to calculate scores for IPC programs as a whole and for each of the 6 indices. RESULTS Of 188 randomly selected facilities, 86 institutions participated. Facilities were compared by region, funding source, and ICP coverage. Overall, LTC facilities lacked IPC leadership, especially physician support. Having no dedicated ICP was associated with poorer scores on all indices. Only 41% of practicing ICPs had more than 2 years experience, and only 14% were professionally certified. Twenty-two percent of ICPs had additional roles within the institution, and 44% had additional roles outside of the institution. Thirty-five percent of institutions had no IPC dedicated budget. DISCUSSION LTC institutions-with bed numbers exceeding those in acute care-represent an important aspect of health services. These data show that many LTC facilities lack the necessary resources to provide quality infection control programs.

Are you prepared? Defining occupational health resource needs to prevent infectious disease transmission in the health care sector.

This article discusses the extent of resource allocation to Occupational Health (OH) to prevent infectious disease exposure and transmission in British Columbia (B.C.). It also characterizes the delineation of roles and responsibilities within OH services in B.C. health care settings and highlights areas where improvements to current OH programs could be made to prevent and control occupational infections. Given the breadth of OH responsibilities, resource allocation in many health care institutions for these services is inadequate and roles and responsibilities may not be clearly delineated.
