Infection prevention and control work environments are highly complex in nature and have long been associated with crisis events including serious infectious disease outbreaks. The role of infection control practitioners shifted exponentially during the COVID-19 pandemic and with this rapid and nebulous change came anxiety, emotional exhaustion and ultimately burnout. Burnout at work generally occurs as a response to chronic and prolonged exposure to emotionally challenging events, causing emotional exhaustion, feelings of cynicism, and lack of accomplishment at work. This systematic review aims to investigate burnout in infection control practitioners during public health crisis events (major outbreaks, epidemics, and pandemics) in upper-middle and high-income countries on a global scale.
A mixed-methods systematic review will be carried out and will include qualitative, quantitative and primary mixed-methods studies that investigate the different elements of burnout, during public health crisis events. After an initial scoping literature search, up to six databases will be searched for studies on burnout in relation to infection prevention practitioners. Study quality will be checked using standardised JBI critical appraisal tools. The proposed review will follow the JBI convergent integrated approach for mixed methods systematic reviews. Following data extraction, quantitative data will then be converted into ‘qualitized data’ in the form of textual descriptions.
It is well documented that adverse conditions during public health crisis events can lead to burnout. This systematic review will investigate of burnout in infection control practitioners in upper-middle and high-income countries during public health crisis events. The findings will inform healthcare professionals, senior policy makers and researchers and will help contribute to a richer understanding of burnout and associated factors in infection control practitioners.

Infection control practitioners (ICPs) have long played pivotal roles during public health crisis events, since the emergence of Severe Acute Respiratory Syndrome (SARS) in 2002, to the more recent SARS-CoV-2 pandemic, more commonly known as COVID-19. With each emerging infectious disease event, ICPs have had to manage the heavy burden associated with excessive workloads, working long hours, constantly changing guidelines, managing serious outbreaks, training frontline workers, and implementation of guidelines to help prevent the transmission of infection. This has contributed significantly to the already high burnout levels in the profession1. The majority of ICPs are trained nurses by profession but some, particularly in the United States, are not trained nurses, but they do hold Certification Board of Infection Control and Epidemiology (CIC®) certification, which requires them to have completed a post-secondary education in a health-related field with the majority being nurses, but also other healthcare professionals. For this reason, this review will focus on both.
Maslach describes burnout as ‘a prolonged response to chronic emotional and interpersonal stressors on the job’ and is characterised by three core domains: emotional exhaustion, feelings of increased distance from work (cynicism), and reduced professional efficacy2. Burnout is a response to sustained work-related stress, with both organisational factors3 such as the emotional demands of work and workload, individual factors2, such as the person’s ability to cope2, and their personality type4. Burnout is also now recognised by the World Health Organization (WHO) as an occupational phenomenon and defined as “a syndrome conceptualised as resulting from chronic workplace stress that has not been successfully managed”5.
Research strongly suggests that burnout in nurses is prevalent, particularly during the early career period or those who experience redeployment to the front line during public health crisis events (e.g., COVID-19)6,7 Older nurses are also affected, leading to many leaving the profession well before retirement8–11. Organisational issues, including lack of autonomy12 and poor social supports can also contribute to burnout13, which can result in reduced work efficacy14,15 and higher rates of absenteeism16. Additionally, patient mortality rates are reported to be higher in hospitals with higher rates of nurse burnout17,18 and more recently, a study reported a correlation between nurse burnout and the implementation of infection prevention and control measures19.
This mixed-methods systematic review (MMSR) aims to evaluate the quantitative, qualitative, and primary mixed-method studies pertaining to infection control practitioner burnout factors (emotional exhaustion; feelings of increased distance from work/cynicism; reduced professional efficacy), and a response to sustained work-related stress, including organisational factors (e.g., the emotional demands of work and workload), individual factors (e.g., a person’s ability to cope), and personality type, during public health crisis events (extended outbreaks, epidemics, and pandemics), in upper-middle to high-income countries.
This MMSR protocol, which is visually represented below, incorporates the PICo framework (Population, Phenomenon of Interest, COntext) as recommended by JBI for MMSR20. The PICo framework (Table 1) will facilitate the identification of the defining characteristics for the study inclusion criteria.
Population: The review will consider studies that include only ICPs. Other healthcare staff (including students) will be excluded from the study. Studies will be excluded if they did not differentiate between for example, general nurses and ICPs.
Phenomena of interest: This review will consider studies that investigate the different elements of burnout and other associated factors such as organisational challenges, during public health crisis events as defined above.
Context: This review will consider studies from upper-middle and high-income countries and will include ICPs who work in both acute and non-acute healthcare settings.
Types of studies: This review will consider quantitative (cross-sectional and cohort or longitudinal studies) and qualitative (interviews, focus groups, case studies, image-based methods), and mixed methods studies. Primary mixed-methods studies will be included if the data can explicitly be extracted from the respective components21. Included studies will comprise of published, peer-reviewed, full text articles. Unpublished articles (grey literature) will not be included.
The proposed systematic review will follow the JBI convergent integrated approach for mixed methods systematic reviews20. This methodology is justified as it will allow for a methodical and rigorous approach and provide a contextual understanding of the topic which further enhances reliability by combining different categories of evidence22. This approach is preferable, because the review question can be addressed by both quantitative and qualitative research principles. Following data extraction, quantitative data will then be converted into ‘qualitized data’ in the form of textual descriptions23.
An initial search of PubMed, Google Scholar, Cochrane, and PROSPERO did not yield any systematic reviews investigating burnout in ICPs hence, this review is the first to examine burnout in this cohort.
The search strategy aims to locate published studies only. JBI methodological guidance recommends a three-phase search strategy, the first of which is a broad initial search of at least two databases24. A broad preliminary search of the literature was performed using Google Scholar and OneSearch (UCC Library default search engine) to identify relevant papers. Having completed the broad preliminary search of the literature, it was decided to include upper middle income countries as there were a number of specific burnout papers relating to IPCs found that were too important to exclude in this review. PROSPERO has also been updated. Following the preliminary search, the text words contained in the titles and abstracts of relevant articles, and the index terms used to describe the articles, were used to develop a full search strategy for the following electronic bibliographic databases: MEDLINE (PubMed), CINAHL (EBSCO), Embase (Elsevier), PsycINFO (EBSCO), Scopus (Elsevier), and Web of Science (Clarivate). The search strategy, including keywords and index terms, will be adapted for each included information source. Additionally, reference lists of studies selected for critical appraisal, will be screened for additional studies. Boolean operators and controlled vocabulary terms will be used as required for each database search.
Searches published in English will be included. Studies published from November 2002 to August 2024 will be included, as the first public health crisis event experienced by ICPs was Severe Acute Respiratory Syndrome (SARS), first identified in November 2002. A sample search strategy (CINAHL) can be found in Extended Data25
Following the search, all identified citations will be loaded into Mendeley Reference Manager (version 2.117.0 /2024) and duplicates removed. These will be imported into the Johanna Briggs Institute, System for the Unified Management, Assessment, and Review of Information (JBI SUMARI)26 for screening. Following a pilot test, titles and abstracts will then be screened by two independent reviewers for assessment against the inclusion criteria for the review. Potentially relevant studies will be retrieved in full, and their citation details imported into JBI SUMARI27. The full text of selected citations will be assessed against the inclusion criteria by two independent reviewers. Reasons for exclusion of full-text studies that do not meet the inclusion criteria will be recorded and reported in the systematic review. Any disagreements that arise between the reviewers at each stage of the study selection process will be resolved through discussion or with a third reviewer. The results of the search will be reported in full in the final review and presented in a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) flow diagram27.
Quantitative papers (and the quantitative component of mixed methods papers) selected for retrieval will be assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical appraisal instruments from JBI SUMARI28.
Qualitative papers (and qualitative component of mixed methods papers) selected for retrieval will be assessed by two independent reviewers for methodological validity prior to inclusion in the review using the standardized critical appraisal instrument from JBI SUMARI29.
Authors of papers will be contacted to request missing or additional data for clarification, where required. Any disagreements that arise between the reviewers will be resolved through discussion or with a third reviewer. The results of critical appraisal will be reported in narrative format and by visual representation in a table.
Following critical appraisal, studies that do not meet the required quality threshold will be excluded.
Quantitative and qualitative data will be extracted from studies included in the review by two independent reviewers using the standardised JBI data extraction tool in JBI SUMARI26 or in RevMan (version 5.0) The data extracted will include specific details about the populations, study methods, phenomena of interest, context etc., and outcomes of relevance to the review question(s). Specifically, quantitative data will be composed of data-based outcomes of descriptive and/or inferential statistical tests23. In addition, qualitative data will be composed of verbatim themes or subthemes with corresponding illustrations and will be assigned a level of credibility depending on the quality of the data23. This protocol was developed in line with the PRISMA-P checklist31, which can be found in Extended Data25.
The quantitative data will be converted into “qualitized” data after data extraction. This will involve transformation into textual descriptions or narrative interpretation of the quantitative results in a way that answers the review questions20.
This study will be submitted for publication in scientific journals and will be publicly available as an open access paper.
The study has been registered on PROSPERO (CRD42024508996). We are currently undergoing systematic searches. Screening, data extraction, synthesis and integration will take place thereafter.
It is well established that adverse conditions during public health crisis events can lead to burnout in ICPs1. Infection prevention and control (IPC) is a relatively young discipline dating back to the 1970s. Research by Melnyk et al., highlighted that 21% of the ICPs were found to be suffering from depression and 29.8% were suffering from anxiety. 74 % of ICPs reported worse mental health and 60% reported worse physical health30. The findings in this report strongly indicate that ICPs are experiencing serious mental health challenges, particularly now in the aftermath of the COVID-19 pandemic30. The MMSR will investigate infection control practitioner burnout in upper-middle to high-income countries during public health crisis events. The findings will inform healthcare professionals, senior policy makers and researchers and will help contribute to a richer understanding of burnout and associated factors in infection control practitioners.
