Twelve tips for how institutional ethnography (IE) is conducted in health professions education research

Institutional ethnography (IE), a term coined by sociologist Dorothy Smith, explores the nuances of institutions and their complex relationships in sociology. IE is an approach to studying and analysing social organization, and it provides a more holistic understanding of 'invisible' relationships that govern institutions and how those relationships interact with each other. Health sciences researchers in patient care, patient experience, and allied health professionals have recently become more interested in the use of this methodology and how to incorporate it into their research. However, in health professions education (HPE) there is little use of IE. We hypothesize this may be because of limited practical knowledge of this methodology. This paper serves as an introduction to the use of IE in HPE, describing the differences between IE and traditional ethnographies, recognizing the common pitfalls when utilising IE, and incorporating texts into IE. While ethnographies may be daunting to researchers less familiar with these approaches, the tips in this paper will provide an introduction and help educators and researchers successfully navigate the use of IE in health profession scholarship and education.

Paediatric inflammatory multisystem syndrome in Canada: population-based surveillance and role of SARS-CoV-2 linkage

BACKGROUND

Paediatric inflammatory multisystem syndrome (PIMS) is a rare condition temporally associated with SARS-CoV-2 infection. Using national surveillance data, we compare presenting features and outcomes among children hospitalized with PIMS by SARS-CoV-2 linkage, and identify risk factors for intensive care (ICU).

METHODS

Cases were reported to the Canadian Paediatric Surveillance Program by a network of >2800 pediatricians between March 2020 and May 2021. Patients with positive versus negative SARS-CoV-2 linkages were compared, with positive linkage defined as any positive molecular or serologic test or close contact with confirmed COVID-19. ICU risk factors were identified with multivariable modified Poisson regression.

RESULTS

We identified 406 children hospitalized with PIMS, including 49.8% with positive SARS-CoV-2 linkages, 26.1% with negative linkages, and 24.1% with unknown linkages. The median age was 5.4 years (IQR 2.5-9.8), 60% were male, and 83% had no comorbidities. Compared to cases with negative linkages, children with positive linkages experienced more cardiac involvement (58.8% vs. 37.4%; p < 0.001), gastrointestinal symptoms (88.6% vs. 63.2%; p < 0.001), and shock (60.9% vs. 16.0%; p < 0.001). Children aged ≥6 years and those with positive linkages were more likely to require ICU.

CONCLUSIONS

Although rare, 30% of PIMS hospitalizations required ICU or respiratory/hemodynamic support, particularly those with positive SARS-CoV-2 linkages.

IMPACT

We describe 406 children hospitalized with paediatric inflammatory multisystem syndrome (PIMS) using nationwide surveillance data, the largest study of PIMS in Canada to date. Our surveillance case definition of PIMS did not require a history of SARS-CoV-2 exposure, and we therefore describe associations of SARS-CoV-2 linkages on clinical features and outcomes of children with PIMS. Children with positive SARS-CoV-2 linkages were older, had more gastrointestinal and cardiac involvement, and hyperinflammatory laboratory picture. Although PIMS is rare, one-third required admission to intensive care, with the greatest risk amongst those aged ≥6 years and those with a SARS-CoV-2 linkage.

Highly pathogenic avian influenza: Unprecedented outbreaks in Canadian wildlife and domestic poultry

Canada experienced a wave of HPAI H5N1 outbreaks in the spring of 2022 with millions of wild and farmed birds being infected. Seabird mortalities in Canada have been particularly severe on the Atlantic Coast over the summer of 2022. Over 7 million birds have been culled in Canada, and outbreaks continue to profoundly affect commercial bird farms across the world. This new H5N1 virus can and has infected multiple mammalian species, including skunks, foxes, bears, mink, seals, porpoises, sea lions, and dolphins. Viruses with mammalian adaptations such as the mutations PB2-E627K, E627V, and D701N were found in the brain of various carnivores in Europe and Canada. To date this specific clade of H5N1 virus has been identified in less than 10 humans. At the ground level, awareness should be raised among frontline practitioners most likely to encounter patients with HPAI.

Resource use and disease severity of children hospitalized for COVID-19 versus multisystem inflammatory syndrome in children (MIS-C) in Canada

Background

Direct comparisons of paediatric hospitalizations for acute coronavirus disease 2019 (COVID-19) and multisystem inflammatory syndrome in children (MIS-C) can inform health system planning. We describe the absolute and relative hospital burden of acute paediatric COVID-19 and MIS-C in Canada.

Methods

This national prospective study was conducted via the Canadian Paediatric Surveillance Program from March 2020-May 2021. Children younger than 18 years old and hospitalized for acute COVID-19 or MIS-C were included in the analysis. Outcomes included supplemental oxygen (low-flow oxygen or high-flow nasal cannula), ventilation (non-invasive or conventional mechanical), vasopressors, paediatric intensive care unit (PICU) admission, or death. Adjusted risk differences (aRD) and 95% confidence intervals (CI) were calculated to identify factors associated with each diagnosis.

Results

Overall, we identified 330 children hospitalized for acute COVID-19 (including five deaths) and 208 hospitalized for MIS-C (including zero deaths); PICU admission was required for 49.5% of MIS-C hospitalizations versus 18.2% of acute COVID-19 hospitalizations (aRD 20.3; 95% CI, 9.9-30.8). Resource use differed by age, with children younger than one year hospitalized more often for acute COVID-19 (aRD 43.4% versus MIS-C; 95% CI, 37.7-49.1) and more children 5-11 years hospitalized for MIS-C (aRD 38.9% vs. acute COVID-19; 95% CI, 31.0-46.9).

Conclusion

While there were more hospitalizations and deaths from acute paediatric COVID-19, MIS-C cases were more severe, requiring more intensive care and vasopressor support. Our findings suggest that both acute COVID-19 and MIS-C should be considered when assessing the overall burden of severe acute respiratory syndrome coronavirus 2 in hospitalized children.

Biomarkers of Growth Faltering and Neurodevelopmental Delay in Children who are HIV-Exposed but Uninfected: A Systematic Review

INTRODUCTION

Children who are HIV-exposed but uninfected (CHEU) are at risk of linear growth faltering and neurodevelopmental delay. Circulating biomarkers associated with these adverse outcomes may elucidate pathways of injury.

OBJECTIVE

To identify biomarkers associated with growth faltering and neurodevelopmental delay in CHEU.

METHODS

We performed a systematic review of electronic databases MEDLINE (1946-April 2021), EMBASE (1974-April 2021), Scopus (2004-April 2021), and PubMed (1985-April 2021), following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The systematic review was registered on the International Prospective Register of Systematic Reviews (PROSPERO, registration number CRD42021238363).

RESULTS

We found seven studies associating biomarker abnormalities and growth outcomes in CHEUs and two studies on biomarker abnormalities and neurodevelopmental delay. Biomarker abnormalities associated with growth restriction were: C-reactive protein (CRP), tumour necrosis factor (TNF), interferon-gamma (IFN-γ), interleukin (IL)-12p70, IFN-γ-induced protein-10 (CXCL10/IP-10), lipopolysaccharide binding protein (LBP), insulin-like growth factor-1 (IGF-1), and IGF-binding protein-1 (IGFBP-1). Biomarkers associated with motor, language, and cognitive delay were CRP, IFN-γ, IL-1β, -2, -4, -6, -10, -12p70, neutrophil gelatinase-associated lipocalin (NGAL), granulocyte-macrophage colony-stimulating factor (GM-CSF), and matrix metalloproteinase- 9 (MMP-9).

CONCLUSION

Elevated markers of inflammation (acute phase reactants, pro-inflammatory cytokines, chemokines) and intestinal microbial translocation are associated with growth faltering. Elevated markers of inflammation are associated with adverse neurodevelopment.

50 Risk factors for severe COVID-19 in hospitalized children in Canada: A national prospective study from March 2020–May 2021

Background

Children living with chronic comorbid conditions are at increased risk for severe COVID-19 disease, though there is limited evidence regarding the risks associated with specific conditions and which children may benefit from targeted COVID-19 therapies. Age-specific baseline indicators of COVID-19 severity are also needed to evaluate the effectiveness of SARS-CoV-2 vaccination strategies in the paediatric population.

Objectives

In this study, we aimed to 1) identify factors associated with severe COVID-19 in children, and 2) describe rates of hospitalization, intensive care unit (ICU) admission, and severe COVID-19 within specific pediatric age groups.

Design/Methods

We conducted a national prospective study on hospitalized children with microbiologically confirmed SARS-CoV-2 infection via the Canadian Paediatric Surveillance Program from March 2020–May 2021. Cases were reported voluntarily by a network of >2800 paediatricians and paediatric subspecialists. SARS-CoV-2 hospitalizations were classified as COVID-19-related, incidental infection, or infection control/social admissions. Severe disease was defined as intensive care, ventilatory or hemodynamic requirements, select organ system complications, or death. Outcomes were described among children aged <6 months, 6–23 months, 2–4 years, 5–11 years, and 12–17 years. Risk factors for severe disease were identified using multivariable Poisson regression, adjusting for child age and sex, coinfections, and timing of hospitalization.

Results

We identified 541 children hospitalized with SARS-CoV-2 infection, including 329 (60.8%) with COVID-19-related disease. Median age at admission was 2.8 years (IQR 0.3-13.5) and 42.9% (n=232) had at least one comorbidity. Among COVID-19-related hospitalizations, severe disease occurred in 29.5% of children (n=97/329), including a higher proportion of children aged 2–4 years (48.7%) and 12–17 years (41.3%) (Table 1). Comorbidities associated with severe disease are described in Figure 1, and included technology dependence (adjusted risk ratio [aRR] 1.96, 95% confidence interval [CI] 1.31-2.95), neurologic conditions (e.g. epilepsy and chromosomal/genetic conditions) (aRR 1.87, 95% CI 1.34-2.61), and pulmonary conditions (e.g. bronchopulmonary dysplasia and uncontrolled asthma) (aRR 1.66, 95% CI 1.13-2.42).

Conclusion

While severe outcomes were detected at all ages and among patients with and without comorbidities, neurologic and pulmonary conditions as well as technology dependence were associated with increased risk of severe COVID-19. Children aged 2–4 years more commonly experienced severe COVID-19 in this study, which was conducted at a time when no children were eligible for SARS-CoV-2 vaccines. Notably, this high-risk group remains without access to approved vaccines. These findings may help guide vaccination programs and prioritize targeted COVID-19 therapies for children.

Invasive pneumococcal disease and long-term outcomes in children: A 20-year population cohort study

BACKGROUND

Although vaccination against Streptococcus pneumoniae infections (such as invasive pneumococcal disease (IPD)) are available, challenges remain in prevention efforts. Moreover, downstream sequelae in children is relatively unknown. Thus, we aimed to evaluate short and long-term health outcomes among children with IPD.

METHODS

Analysis of Streptococcus pneumoniae positive isolates from sterile body sites in children (0-17 years) in Alberta (Canada) from 1999 to 2019 was performed retrospectively (n=888). Cases were age and sex-matched to hospitalized population controls. Linkage to administrative health datasets was done to determine comorbidities and healthcare related outcomes. Cox proportional hazards were used to assess differences in time to mortality and hospitalisation between cases and controls in short (<30-day), intermediate (30-90 day), long-term (>90-day) follow-up.

FINDINGS

Proportionally more deaths occurred in cases (4.8 deaths/1000 person-years (PY)) than controls (2.7 deaths/1000 PY), leading to a significant adjusted hazard ratio (aHR) of 1.80 (95% CI 1.22-2.64). This increased risk of death was influenced primarily by short-term mortality (319 vs 36 deaths/1000 PY in cases vs controls respectively, aHR 8.78 [95% CI 3.33-23.18]), as no differences were seen in intermediate (14 vs 7 deaths/1000 PY; aHR 2.03, 95% CI 0.41-10.04) or long-term time intervals (2.4 vs 2.3 deaths/1000 PY, aHR 1.03, 95% CI 0.63-1.69).

INTERPRETATION

IPD continues to negatively impact survival in children despite vaccination. Although long-term impact on mortality and hospitalisations may not be substantial, the immediate effects of IPD are significant.

Caractéristiques des hospitalisations au Canada d’enfants ayant contracté une infection aiguë par le SRAS-CoV-2 en 2020

Contexte:

Les facteurs de risque de complications graves de l’infection par le SRAS-CoV-2 n’ont pas été bien établis chez les enfants. Nous avons voulu décrire les hospitalisations pédiatriques associées au SRAS-CoV-2 au Canada et identifier les facteurs de risque de maladie grave.

Méthodes:

Nous avons procédé à une étude prospective nationale en utilisant l’infrastructure du Programme canadien de surveillance pédiatrique (PCSP). Les hospitalisations d’enfants ayant contracté une infection par le SRAS-CoV-2 confirmée en laboratoire de microbiologie ont été rapportées du 8 avril au 31 décembre 2020 au moyen de questionnaires hebdomadaires en ligne distribués au réseau du PCSP, qui compte plus de 2800 pédiatres. Nous avons catégorisé les hospitalisations comme suit : liées à la COVID-19, infections découvertes fortuitement, ou hospitalisations pour des raisons sociales ou de contrôle des infections, et dégagé les facteurs de risque associés à la gravité de la maladie chez les patients hospitalisés.

Résultats:

Sur les 264 hospitalisations d’enfants ayant contracté le SRAS-CoV-2 au cours de la période de l’étude de 9 mois, 150 (56,8 %) ont été associées à la COVID-19 et 100 (37,9 %) étaient des cas découverts fortuitement (admission pour d’autres raisons et découverte fortuite du SRAS-CoV-2 par dépistage positif). Les nourrissons (37,3 %) et les adolescents (29,6 %) représentaient la majorité des cas. Parmi les hospitalisations liées à la COVID-19, 52 patients (34,7 %) étaient atteints d’une forme grave de la maladie, dont 42 (28,0 % des cas liés à la COVID-19) ont eu besoin d’une forme d’assistance respiratoire ou hémodynamique, et 59 (39,3 %) présentaient au moins 1 comorbidité sous-jacente. Les enfants atteints d’obésité, de maladies neurologiques chroniques ou de maladies pulmonaires chroniques, à l’exclusion de l’asthme, étaient plus susceptibles de présenter une forme grave ou critique de la COVID-19.

Interprétation:

Parmi les enfants hospitalisés au Canada chez lesquels on a diagnostiqué une infection par le SRAS-CoV-2 au début de la pandémie de COVID-19, la découverte fortuite du SRAS-CoV-2 a été fréquente. Chez les enfants hospitalisés pour une COVID-19 aiguë, l’obésité et les comorbidités neurologiques et respiratoires ont été associées à une gravité accrue.

Characteristics of children admitted to hospital with acute SARS-CoV-2 infection in Canada in 2020

Background:

Risk factors for severe outcomes of SARS-CoV-2 infection are not well established in children. We sought to describe pediatric hospital admissions associated with SARS-CoV-2 infection in Canada and identify risk factors for more severe disease.

Methods:

We conducted a national prospective study using the infrastructure of the Canadian Paediatric Surveillance Program (CPSP). Cases involving children who were admitted to hospital with microbiologically confirmed SARS-CoV-2 infection were reported from Apr. 8 to Dec. 31 2020, through weekly online questionnaires distributed to the CPSP network of more than 2800 pediatricians. We categorized hospital admissions as related to COVID-19, incidental, or for social or infection control reasons and determined risk factors for disease severity in hospital.

Results:

Among 264 hospital admissions involving children with SARS-CoV-2 infection during the 9-month study period, 150 (56.8%) admissions were related to COVID-19 and 100 (37.9%) were incidental infections (admissions for other reasons and found to be positive for SARS-CoV-2 on screening). Infants (37.3%) and adolescents (29.6%) represented most cases. Among hospital admissions related to COVID-19, 52 (34.7%) had critical disease, 42 (28.0%) of whom required any form of respiratory or hemodynamic support, and 59 (39.3%) had at least 1 underlying comorbidity. Children with obesity, chronic neurologic conditions or chronic lung disease other than asthma were more likely to have severe or critical COVID-19.

Interpretation:

Among children who were admitted to hospital with SARS-CoV-2 infection in Canada during the early COVID-19 pandemic period, incidental SARS-CoV-2 infection was common. In children admitted with acute COVID-19, obesity and neurologic and respiratory comorbidities were associated with more severe disease.

Growth Faltering and Developmental Delay in HIV-Exposed Uninfected Ugandan Infants: A Prospective Cohort Study

BACKGROUND

HIV-exposed but uninfected (HEU) infants are at increased risk of impaired early linear growth and cognitive development. We examined associations between prenatal and postnatal growth and subsequent neurodevelopment in Ugandan HEU infants, hypothesizing that early insults may explain alterations in both somatic growth and brain development.

METHODS

We prospectively followed a cohort of HEU infants from birth to 18 months of age, and measured length/height, weight, head, and arm circumference longitudinally. The Malawi Development Assessment Tool (MDAT, 12 and 18 months) and the Color Object Association Test (18 months) were used for developmental assessments.

RESULTS

Among 170 HEU infants, the prevalence of low-birth weight and failure to thrive was 7.6% and 37%, respectively. HEU infants had MDAT scores that were similar to the reference population. The mean (SD) score on the Color Object Association Test was 5.5 (3.1) compared with 6.9 (5.3) in developmentally normal children. Developmental ability at age 18 months showed strong cross-sectional correlation with weight-for-age (ρ = 0.36, P < 0.0001), length/height-for-age (ρ = 0.41, P < 0.0001), head circumference-for-age (ρ = 0.26, P = 0.0011), and mid-upper arm circumference-for-age (ρ = 0.34, P = 0.0014). There was a statistically significant correlation between birth weight and MDAT z-score at 18 months (ρ = 0.20, P = 0.010). Failure to thrive was associated with lower MDAT z-score [median -0.13 (IQR -0.75 to +0.14) versus +0.14 (IQR -0.44 to +0.63), P = 0.042].

CONCLUSION

Growth faltering in HEU infants was associated with lower attainment of developmental milestones at age 18 months. Our findings point to a simple screening method for identifying HEU infants at risk for developmental intervention.

Non-polio Enterovirus detection with acute flaccid paralysis: A systematic review

Acute flaccid paralysis (AFP), as defined by the World Health Organization (WHO), is characterized by an acute onset of limb weakness. In the post-polio era, other enterovirus (EV) serotypes associated with AFP may become more prominent. This study aims to collate the data on the non-polio enteroviruses (NPEV) associated with AFP. A systematic review of published case reports, case series, and surveillance studies of AFP from 1960 through 2017 was undertaken. Data were collected including the country of the study, number of specimens positive for NPEV and available clinical data. The majority of studies originated from Asia. In surveillance studies, EV 71 (a serotype of Enterovirus A) was the most commonly detected serotype with AFP, followed by Enterovirus B serotype echovirus 11 and then Enterovirus B serotype echovirus 11. In case studies and case reports, EV 71 and EV 68 (a serotype of Enterovirus D), were the most commonly detected NPEV. As poliovirus eradication continues, there is a need to ensure that AFP surveillance will also detect other potentially vaccine preventable viruses.

Central venous catheter repair is not associated with an increased risk of central line infection or colonization in intestinal failure pediatric patients

PURPOSE

The intestinal failure (IF) population is dependent upon central venous catheters (CVC) to maintain minimal energy requirements for growth. Central venous catheter infections (CVCI) are frequent and an independent predictor of intestinal failure associated liver disease. A common complication in children with long-term CVC is the risk of line breakage. Given the often-limited usable vascular access sites in this population, it has been the standard of practice to perform repair of the broken line. Although widely practiced, it is unknown if this practice is associated with increased line colonization rates and subsequent line loss.

METHODS

A retrospective review of our institutional IF population over the past 8years (2006-2014) was performed. Utilizing a prospectively constructed database, all pediatric patients (n=13, ages 0-17 years) with CVC dependency enrolled in the Children's Intestinal Rehabilitation Program with IF were included who underwent a repair and/or replacement procedure of their line. The control replacement group was CVCs that were replaced without being repaired (36), the experimental repair group was CVCs that were repaired (8). The primary outcome of interest was the mean number of days in each group from the intervention (replacement or repair) to line infection/colonization. Mann-Whitney tests for significance were performed with p-values <0.05 being the threshold value for significance.

RESULTS

There were no catheter repair associated CVCI. The mean number of days from the replacement or repair of a CVC to its removal owing to infection/colonization was 210.0 and 162.8days respectively. There was no statistically significant difference between these groups in time to removal owing to line infection (p=0.55).

CONCLUSION

Repair of central venous catheters in the pediatric population with intestinal failure does not lead to an increased rate of central venous catheter infection and should be performed when possible.

Ralstonia pickettiiBacteremia Associated With Pediatric Extracorporeal Membrane Oxygenation Therapy in a Canadian Hospital

We describe 2 pediatric patients withRalstonia pickettiibacteremia associated with extracorporeal membrane oxygenation (ECMO) therapy. Investigation revealed a common environmental source—the ECMO temperature-control units. We created guidelines for disinfecting these units that do not void the manufacturer's warranty and have prevented additional cases of bacteremia due to this organism.

Parenteral and oral antibiotic duration for treatment of pediatric osteomyelitis: a systematic review protocol

BACKGROUND

Pediatric osteomyelitis is a bacterial infection of bones requiring prolonged antibiotic treatment using parenteral followed by enteral agents. Major complications of pediatric osteomyelitis include transition to chronic osteomyelitis, formation of subperiosteal abscesses, extension of infection into the joint, and permanent bony deformity or limb shortening. Historically, osteomyelitis has been treated with long durations of antibiotics to avoid these complications. However, with improvements in management and antibiotic treatment, standard of care is moving towards short durations of intravenous antibiotics prior to enteral antibiotics.

METHODS/DESIGN

The authors will perform a systematic review based on PRISMA guidelines in order to evaluate the literature, looking for evidence to support the optimal duration of parenteral and enteral therapy. The main goals are to see if literature supports shorter durations of either parenteral antibiotics and/or enteral antibiotics.Multiple databases will be investigated using a thorough search strategy. Databases include Medline, Cochrane, EMBASE, SCOPUS, Dissertation Abstracts, CINAHL, Web of Science, African Index Medicus and LILACS. Search stream will include medical subject heading for pediatric patients with osteomyelitis and antibiotic therapy. We will search for published or unpublished randomized and quasi-randomized controlled trials.Two authors will independently select articles, extract data and assess risk of bias by standard Cochrane methodologies. We will analyze comparisons between dichotomous outcomes using risk ratios and continuous outcomes using mean differences. 95% confidence intervals will be computed.

DISCUSSION

One of the major dilemmas of management of this disease is the duration of parenteral therapy. Long parenteral therapy has increased risk of serious complications and the necessity for long therapy has been called into question. Our study aims to review the currently available evidence from randomized trials regarding duration of both parenteral and oral therapy for pediatric acute osteomyelitis.

Are health care workers protected? An observational study of selection and removal of personal protective equipment in Canadian acute care hospitals

BACKGROUND

The proper use of personal protective equipment (PPE) by health care workers (HCWs) is vital in preventing the spread of infection and has implications for HCW safety.

METHODS

An observational study was performed in 11 hospitals participating in the Canadian Nosocomial Infection Surveillance Program between January 7 and March 30, 2011. Using a standardized data collection tool, observers recorded HCWs selecting and removing PPE and performing hand hygiene on entry into the rooms of febrile respiratory illness patients.

RESULTS

The majority of HCWs put on gloves (88%, n = 390), gown (83%, n = 368), and mask (88%, n = 386). Only 37% (n = 163) were observed to have put on eye protection. Working in a pediatric unit was significantly associated with not wearing eye protection (7%), gown (70%), gloves (77%), or mask (79%). Half of the observed HCWs (54%, n = 206) removed their PPE in the correct sequence. Twenty-six percent performed hand hygiene after removing their gloves, 46% after removing their gown, and 57% after removing their mask and/or eye protection.

CONCLUSION

Overall adherence with appropriate PPE use in health care settings involving febrile respiratory illness patients was modest, particularly on pediatric units. Interventions to improve PPE use should be targeted toward the use of recommended precautions (eg, eye protection), HCWs working in pediatric units, the correct sequence of PPE removal, and performing hand hygiene.

Attitudes and beliefs about hand hygiene among paediatric residents: a qualitative study

BACKGROUND

Despite the knowledge that contaminated hands play an important role in the transmission of healthcare-associated pathogens, and that hand hygiene (HH) reduces the transmission of these organisms, healthcare worker's adherence with HH is poor.

OBJECTIVE

To understand the common beliefs and attitudes held by paediatric residents about HH.

DESIGN

Qualitative study design.

SETTING

Tertiary care paediatric hospital in Edmonton, Canada.

METHODS

Semistructured interviews were conducted and themes were identified from interviews.

PARTICIPANTS

22 paediatric residents.

RESULTS

Paediatric residents self-reported their HH adherence at 70-99% and perceived hospital-wide adherence at 45-80%. Four major themes were identified during interviews including the importance of role modelling, balancing time spent on HH with other competing factors, self-protection as a driving factor for HH and cues as an important part of habit that stimulate HH.

CONCLUSIONS

Staff physicians were viewed as integral to initiating group HH events, but at times, the first person in the room acted as a role model for the rest of the group. In certain instances, such as a cardiac arrest, decreased adherence with HH was viewed as acceptable. Residents engaged in HH to protect their own health. Residents relied on personal cues, which they integrated into their own HH habit. Future HH adherence strategies should ensure that the physician training environments permit the formation of good attitudes and habits towards HH. There are no additional data available.

Healthcare-associated atypical pneumonia

Atypical pneumonia was first described in 1938, and over time, Mycoplasma, Legionella, and Chlamydophila were the agents commonly linked with community-associated atypical pneumonia. However, as technology has improved, so has our understanding of this clinical entity. It is now known that there are many agents linked with atypical pneumonia in the community, and many of these agents are also major causes of healthcare-associated pneumonia. This article discusses the history, epidemiology, and pathogenesis of infection; control of infection; clinical findings; diagnosis; and, where applicable, treatment of the agents of healthcare-associated atypical pneumonia. Bacterial agents include Legionella species, Mycoplasma pneumoniae, Chlamydophila species, and Coxiella burnetii. Although there are over 100 viruses that can cause respiratory tract infections, only a fraction of those have been defined in the context of healthcare-associated atypical pneumonia: adenovirus and human bocavirus (HBoV); rhinovirus; human coronaviruses (HCoV), including HCoV 229E, HCoV OC43, HCoV NL63, HCoV HKU1; members of the paramyxoviridae (parainfluenza viruses, human metapneumovirus, and respiratory syncytial virus); hantavirus; influenza; and severe acute respiratory syndrome (SARS) Co-V. Our knowledge about healthcare-associated atypical pneumonia will continue to evolve as newer pathogens are identified and as newer diagnostic modalities such as multiplex polymerase chain reaction are introduced.

Bacterial contamination of health care workers' pagers and the efficacy of various disinfecting agents

Health care workers in our facility were surveyed, and their pagers were cultured before and after disinfection with various agents. All pagers were contaminated with bacteria, including the pathogens Staphylococcus aureus, Pseudomonas aeruginosa, Acinetobacter baumannii, Klebsiella spp. and methicillin-resistant S. aureus. Disinfection reduced bacterial contamination. No risk factors for pager contamination with pathogens were identified.
