Training programs to improve identification of sick newborns and care-seeking from a health facility in low- and middle-income countries: a scoping review.

BACKGROUND: Most neonatal deaths occur in low- and middle-income countries (LMICs). Limited recommendations are available on the optimal personnel and training required to improve identification of sick newborns and care-seeking from a health facility. We conducted a scoping review to map the key components required to design an effective newborn care training program for community-based health workers (CBHWs) to improve identification of sick newborns and care-seeking from a health facility in LMICs. METHODS: We searched multiple databases from 1990 to March 2020. Employing iterative scoping review methodology, we narrowed our inclusion criteria as we became more familiar with the evidence base. We initially included any manuscripts that captured the concepts of "postnatal care providers," "neonates" and "LMICs." We subsequently included articles that investigated the effectiveness of newborn care provision by CBHWs, defined as non-professional paid or volunteer health workers based in communities, and their training programs in improving identification of newborns with serious illness and care-seeking from a health facility in LMICs. RESULTS: Of 11,647 articles identified, 635 met initial inclusion criteria. Among these initial results, 35 studies met the revised inclusion criteria. Studies represented 11 different types of newborn care providers in 11 countries. The most commonly studied providers were community health workers. Key outcomes to be measured when designing a training program and intervention to increase appropriate assessment of sick newborns at a health facility include high newborn care provider and caregiver knowledge of newborn danger signs, accurate provider and caregiver identification of sick newborns and appropriate care-seeking from a health facility either through caregiver referral compliance or caregivers seeking care themselves. Key components to consider to achieve these outcomes include facilitators: sufficient duration of training, refresher training, supervision and community engagement; barriers: context-specific perceptions of newborn illness and gender roles that may deter care-seeking; and components with unclear benefit: qualifications prior to training and incentives and remuneration. CONCLUSION: Evidence regarding key components and outcomes of newborn care training programs to improve CBHW identification of sick newborns and care-seeking can inform future newborn care training design in LMICs. These training components must be adapted to country-specific contexts.

Risk factors for childhood illness and death in rural Uttar Pradesh, India: perspectives from the community, community health workers and facility staff.

BACKGROUND: Uttar Pradesh (UP), India continues to have a high burden of mortality among young children despite recent improvement. Therefore, it is vital to understand the risk factors associated with under-five (U5) deaths and episodes of severe illness in order to deliver programs targeted at decreasing mortality among U5 children in UP. However, in rural UP, almost every child has one or more commonly described risk factors, such as low socioeconomic status or undernutrition. Determining how risk factors for childhood illness and death are understood by community members, community health workers and facility staff in rural UP is important so that programs can identify the most vulnerable children. METHODS: This qualitative study was completed in three districts of UP that were part of a larger child health program. Twelve semi-structured interviews and 21 focus group discussions with 182 participants were conducted with community members (mothers and heads of households with U5 children), community health workers (CHWs; Accredited Social Health Activists and Auxiliary Nurse Midwives) and facility staff (medical officers and staff nurses). All interactions were recorded, transcribed and translated into English, coded and clustered by theme for analysis. The data presented are thematic areas that emerged around perceived risk factors for childhood illness and death. RESULTS: There were key differences among the three groups regarding the explanatory perspectives for identified risk factors. Some perspectives were completely divergent, such as why the location of the housing was a risk factor, whereas others were convergent, including the impact of seasonality and certain occupational factors. The classic explanatory risk factors for childhood illness and death identified in household surveys were often perceived as key risk factors by facility staff but not community members. However, overlapping views were frequently expressed by two of the groups with the CHWs bridging the perspectives of the community members and facility staff. CONCLUSION: The bridging views of the CHWs can be leveraged to identify and focus their activities on the most vulnerable children in the communities they serve, link them to facilities when they become ill and drive innovations in program delivery throughout the community-facility continuum.

Association of identification of facility and transportation for childbirth with institutional delivery in high priority districts of Uttar Pradesh, India.

BACKGROUND: Timely and skilled care is key to reducing maternal and neonatal mortality. Birth preparedness involves preparation for safe childbirth during the antenatal period to reach the appropriate health facility for ensuring safe delivery. Hence, understanding the factors associated with birth preparedness and its significance for safe delivery is essential. This paper aims to assess the levels of birth preparedness, its determinants and association with institutional deliveries in High Priority Districts of Uttar Pradesh, India. METHODS: A community-based cross-sectional survey was conducted between June-October 2018 in the rural areas of 25 high priority districts of Uttar Pradesh, India. Simple random sampling was used to select 40 blocks among 294 blocks in 25 districts and 2646 primary sampling units within the selected blocks. The survey interviewed 9458 women who had a delivery 2 months prior to the survey. Descriptive statistics were included to characterize the study population. Multivariable logistic regression analyses were performed to identify the determinants of birth preparedness and to examine the association of birth preparedness with institutional delivery. RESULTS: Among the 9458 respondents, 61.8% had birth preparedness (both facility and transportation identified) and 79.1% delivered in a health facility. Women in other caste category (aOR = 1.24, CI 1.06-1.45) and those with 10 or more years of education (aOR = 1.68, CI 1.46-1.92) were more likely to have birth preparedness. Antenatal care (ANC) service uptake related factors like early registration for ANC (aOR = 1.14, CI 1.04-1.25) and three or more front line worker contacts (aOR = 1.61, CI 1.46-1.79) were also found to be significantly associated with birth preparedness. The adjusted multivariate model showed that those who identified both facility and transport were seven times more likely to undergo delivery in a health facility (aOR = 7.00, CI 6.07-8.08). CONCLUSION: The results indicate the need for focussing on marginalized groups for improving birth preparedness. Increasing ANC registration in the first trimester of pregnancy, improving frontline worker contact, and optimum utilization of antenatal care check-ups for effective counselling on birth preparedness along with system level improvements could improve birth preparedness and consequently institutional delivery rates in Uttar Pradesh, India.

Readiness to provide child health services in rural Uttar Pradesh, India: mapping, monitoring and ongoing supportive supervision.

BACKGROUND: In 2018, 875 000 under-five children died in India with children from poor families and rural communities disproportionately affected. Community health centres are positioned to improve access to quality child health services but capacity is often low and the systems for improvements are weak. METHODS: Secondary analysis of child health program data from the Uttar Pradesh Technical Support Unit was used to delineate how program activities were temporally related to public facility readiness to provide child health services including inpatient admissions. Fifteen community health centres were mapped regarding capacity to provide child health services in July 2015. Mapped domains included human resources and training, infrastructure, equipment, drugs/supplies and child health services. Results were disseminated to district health managers. Six months following dissemination, Clinical Support Officers began regular supportive supervision and gaps were discussed monthly with health managers. Senior pediatric residents mentored medical officers over a three-month period. Improvements were assessed using a composite score of facility readiness for child health services in July 2016. Usage of outpatient and inpatient services by under-five children was also assessed. RESULTS: The median essential composition score increased from 0.59 to 0.78 between July 2015 and July 2016 (maximum score of 1) and the median desirable composite increased from 0.44 to 0.58. The components contributing most to the change were equipment, drugs and supplies and service provision. Scores for trained human resources and infrastructure did not change between assessments. The number of facilities providing some admission services for sick children increased from 1 in July 2015 to 9 in October 2016. CONCLUSIONS: Facility readiness for the provision of child health services in Uttar Pradesh was improved with relatively low inputs and targeted assessment. However, these improvements were only translated into admissions for sick children when clinical mentoring was included in the support provided to facilities.

Potential contributions of an on-site nurse mentoring program on neonatal mortality reductions in rural Karnataka state, South India: evidence from repeat community cross-sectional surveys.

BACKGROUND: We assessed the effects of a nurse mentoring program on neonatal mortality in eight districts in India. METHODS: From 2012 to 2015, nurse mentors supported improvements in critical MNCH-related practices among health providers at primary health centres (PHCs) in northern Karnataka, South India. Baseline (n = 5240) and endline (n = 5154) surveys of randomly selected ever-married women were conducted. Neonatal mortality rates (NMR) among the last live-born children in the three years prior to each survey delivered in NM and non-NM-supported facilities were calculated and compared using survival analysis and cumulative hazard function. Mortality rates on days 1, 2-7 and 8-28 post-partum were compared. Cox survival regression analysis measured the adjusted effect on neonatal mortality of delivering in a nurse mentor supported facility. RESULTS: Overall, neonatal mortality rate in the three years preceding the baseline and endline surveys was 30.5 (95% CI 24.3-38.4) and 21.6 (95% CI 16.3-28.7) respectively. There was a substantial decline in neonatal mortality between the survey rounds among children delivered in PHCs supported by NM: 29.4 (95% CI 18.1-47.5) vs. 9.3 (95% CI 3.9-22.3) (p = 0.09). No significant declines in neonatal mortality rate were observed among children delivered in other facilities or at home. In regression analysis, among children born in nurse mentor supported facilities, the estimated hazard ratio at endline was significantly lower compared with baseline (HR: 0.23, 95% CI: 0.06-0.82, p = 0.02). CONCLUSION: The nurse mentoring program was associated with a substantial reduction in neonatal mortality. Further research is warranted to delineate whether this may be an effective strategy for reducing NMR in resource-poor settings.

'Know-Can' gap: gap between knowledge and skills related to childhood diarrhoea and pneumonia among frontline workers in rural Uttar Pradesh, India.

OBJECTIVES: In India, frontline workers (FLWs) - public accredited social health activists (ASHAs) and private rural medical providers (RMPs) - are important for early detection and treatment of childhood diarrhoea and pneumonia. This cross-sectional study aims to measure knowledge and skills, and the gap between the two ('know-can' gap), regarding assessment of childhood diarrhoea with dehydration and pneumonia among FLWs, and to explore factors associated with them. METHODS: We surveyed 473 ASHAs and 447 RMPs in six districts of Uttar Pradesh. We assessed knowledge and skills using face-to-face interviews and video vignettes, respectively, about key signs of both conditions. The 'know-can' gap corresponds to absent skills among FLWs with correct knowledge. We used logistic regression to identify the correlates of knowledge and skills. RESULTS: FLWs' correct knowledge ranged from 23% to 48% for dehydration signs and 27% to 37% for pneumonia signs. Their skills ranged from 3% to 42% for dehydration and 3% to 18% for pneumonia. There was a significant 'know-can' gap in all the signs, except 'sunken eyes'. Training and supervisory support was associated with better knowledge and skills for diarrhoea with dehydration, but only better knowledge for pneumonia. CONCLUSIONS: FLWs are crucial to the Indian health system, and high-quality FLW services are necessary for continued progress against under-five deaths. The gap between FLWs' knowledge and skills warrants immediate attention. In particular, our results suggest that knowledge-focused trainings are insufficient for FLWs to convert knowledge into appropriate assessment skills.

OBJECTIFS: En Inde, les travailleurs de première ligne (TPL) - activistes de la santé sociale accrédités par le public (ASSAP) et prestataires médicaux ruraux privés (PMRP) - sont importants pour la détection et le traitement précoces de la diarrhée et de la pneumonie infantiles. Cette étude transversale vise à mesurer les connaissances et les compétences, et l'écart entre les deux (écart ''savoir-pouvoir''), en ce qui concerne l'évaluation de la diarrhée infantile avec déshydratation et la pneumonie chez les TPL et à explorer les facteurs qui leur sont associés. MÉTHODES: Nous avons mené une enquête sur 473 ASSAP et 447 PMRP dans six districts de l'Uttar Pradesh. Nous avons évalué les connaissances et les compétences à l'aide d'entretiens de face à face et de vignettes vidéo, respectivement, sur les signes clés des deux conditions. L'écart «savoir-pouvoir¼ correspond à des compétences absentes parmi les TPL ayant des connaissances correctes. Nous avons utilisé la régression logistique pour identifier les corrélats des connaissances et des compétences. RÉSULTATS: Les connaissances correctes des TPL variaient de 23% à 48% pour les signes de déshydratation, 27% à 37% pour les signes de pneumonie. Leurs compétences variaient de 3% à 42% pour la déshydratation et de 3% à 18% pour la pneumonie. Il y avait un écart important dans le «savoir-pouvoir¼ pour tous les signes, à l'exception des «yeux enfoncés¼. La formation et le soutien à la supervision étaient associés à de meilleures connaissances et compétences pour la diarrhée avec déshydratation, mais seulement à de meilleures connaissances pour la pneumonie. CONCLUSIONS: Les TPL sont cruciaux pour le système de santé indien, et des services de TPL de haute qualité sont nécessaires pour continuer à lutter contre les décès d'enfants de moins de cinq ans. L'écart entre les connaissances et les compétences des TPL mérite une attention immédiate. En particulier, nos résultats suggèrent que les formations axées sur les connaissances sont insuffisantes pour que les TPL convertissent les connaissances en compétences d'évaluation appropriées.

Determinants of scholarly project completion in a paediatric resident program in Canada.

BACKGROUND: The primary aims of this study were to: 1) assess barriers and facilitators of completing scholarly projects from residents and faculty mentor perspectives, 2) determine the perceived value of new initiatives designed to support resident scholarly projects and 3) determine if these initiatives led to changes in resident publications. DESIGN AND METHODS: Between June and September 2014, we surveyed 18 paediatric residents and 41 faculty mentors regarding barriers to resident scholarly project completion and the value of new initiatives to support scholarly activity. We also tracked scientific publications by residents before and after implementation of these initiatives. RESULTS: The primary perceived barriers to research for residents and faculty were lack of protected time (64.3% versus 68.6%, respectively), lack of resident interest in scholarly activity (50.0% versus 60.0%, respectively) and lack of mentor motivation. Mentors and residents did not agree that lack of proper training in research (29% versus 54%, respectively) and faculty motivation (29% versus 17%, respectively) were barriers to completing a project. A dedicated research coordinator (71.4% versus 70.6%, respectively), a revised research curriculum (71.4% versus 41.2%, respectively) and works in progress sessions (50.0% versus 61.8%, respectively) were perceived as valuable initiatives to the program. These initiatives were not associated with changes in annual resident publication rates. CONCLUSIONS: Lack of time and competing clinical training are primary barriers to scholarly project completion for residents in addition to a lack of motivation on the part of faculty members. Improving program support was perceived as positive changes to address these barriers but did not increase resident publication rates. The information provided here could be used to tailor future resident research programs and highlight the value of gathering input from resident and faculty when designing initiatives to enhance resident research productivity.

Enhancing the capacity and effectiveness of community health volunteers to improve maternal, newborn and child health: Experience from Kenya.

OBJECTIVE: To determine whether a simple monitoring and tracking tool, Mwanzo Mwema Monitoring and Tracking Tool (MMATT), would enable community health volunteers (CHVs) in Kenya to 1) plan their workloads and activities, 2) identify the women, newborns and children most in need of accessing critical maternal, newborn and child health (MNCH) interventions and 3) improve key MNCH indicators. METHODS: A mixed methods approach was used. Household surveys at baseline (n = 912) and endline (n = 1143) collected data on key MNCH indicators in the four subcounties of Taita Taveta County, Kenya. Eight focus group discussions were held with 40 CHVs to ascertain their perspectives on using the tool. RESULTS: Qualitative findings revealed that the CHVs found the MMATT to be useful in planning their activities and prioritizing beneficiaries requiring more support to access MNCH services. They also identified potential barriers to care at both the community and health system levels. At endline, previously pregnant women were more likely to have received four or more antenatal care visits, facility delivery, postnatal care within two weeks of delivery and a complete package of care than baseline respondents. Among women with children under 24 months, those at endline were more likely to report early breastfeeding and exclusive breastfeeding for the first six months. These results remained after adjustment for age, subcounty, gravida, mother's education and asset index. CONCLUSION: Our results demonstrate that simple tools enable CHVs to identify disparities in service delivery and health outcomes, and to identify barriers to MNCH care. Tools that enhance CHVs' ability to plan and prioritize the women and children most in need increase CHVs' potential impact.

A qualitative study on African immigrant and refugee families' experiences of accessing primary health care services in Manitoba, Canada: it's not easy!

BACKGROUND: Immigrant and refugee families form a growing proportion of the Canadian population and experience barriers in accessing primary health care services. The aim of this study was to examine the experiences of access to primary health care by African immigrant and refugee families. METHODS: Eighty-three families originating from 15 African countries took part in multiple open ended interviews in western Canada. Qualitative data was collected in six different languages between 2013 and 2015. Data analysis involved delineating units of meaning from the data, clustering units of meaning to form thematic statements, and extracting themes. RESULTS: African immigrant and refugee families experienced challenges in their quest to access primary health care that were represented by three themes: Expectations not quite met, facing a new life, and let's buddy up to improve access. On the theme of expectations not quite met, families struggled to understand and become familiar with a new health system that presented with a number of barriers including lengthy wait times, a shortage of health care providers, high cost of medication and non-basic health care, and less than ideal care. On the theme of facing a new life, immigrant and refugee families talked of the difficulties of getting used to their new and unfamiliar environments and the barriers that impact their access to health care services. They talked of challenges related to transportation, weather, employment, language and cultural differences, and lack of social support in their quest to access health care services. Additionally, families expressed their lack of social support in accessing care. Privately sponsored families and families with children experienced even less social support. Importantly, in the theme of let's buddy up to improve access, families recommended utilizing networking approaches to engage and improve their access to primary health care services. CONCLUSIONS: African immigrant and refugee families experience barriers to accessing primary health care. To improve access, culturally relevant programs, collaborative networking approaches, and policies that focus on addressing social determinants of health are needed.

Improving the knowledge of labour and delivery nurses in India: a randomized controlled trial of mentoring and case sheets in primary care centres.

BACKGROUND: Birthing in health facilities in India has increased over the last few years, yet maternal and neonatal mortality rates remain high. Clinical mentoring with case sheets or checklists for nurses is viewed as essential for on-going knowledge transfer, particularly where basic training is inadequate. This paper summarizes a study of the effect of such a programme on staff knowledge and skills in a randomized trial of 295 nurses working in 108 Primary Health Centres (PHCs) in Karnataka, India. METHODS: Stratifying by district, half of the PHCs were randomly assigned to be intervention sites and provided with regular mentoring visits where case sheet/checklists were a central job and teaching aid, and half to be control sites, where no support was provided except provision of case sheets. Nurses' knowledge and skills around normal labour, labour complications and neonate issues were tested before the intervention began and again one year later. Univariate and multivariate analyses were conducted to examine the effect of mentoring and case sheets. RESULTS: Overall, on none of the 3 measures, did case sheet use without mentoring add anything to the basic nursing training when controlling for other factors. Only individuals who used both case-sheets and received mentoring scored significantly higher on the normal labour and neonate indices, scoring almost twice as high as those who only used case-sheets. This group was also associated with significantly higher scores on the complications of labour index, with their scores 2.3 times higher on average than the case sheet only control group. Individuals from facilities with 21 or more deliveries in a month tended to fare worse on all 3 indices. There were no differences in outcomes according to district or years of experience. CONCLUSIONS: This study demonstrates that provision of case sheets or checklists alone is insufficient to improve knowledge and practices. However, on-site mentoring in combination with case sheets can have a demonstrable effect on improving nurse knowledge and skills around essential obstetric and neonatal care in remote rural areas of India. We recommend scaling up of this mentoring model in order to improve staff knowledge and skills and reduce maternal and neonatal mortality in India. TRIAL REGISTRATION: This study is registered at clinicaltrials.gov, Identifier No. NCT02004912 , November 27, 2013.

Effectiveness of Onsite Nurse Mentoring in Improving Quality of Institutional Births in the Primary Health Centres of High Priority Districts of Karnataka, South India: A Cluster Randomized Trial.

BACKGROUND: In India, although the proportion of institutional births is increasing, there are concerns regarding quality of care. We assessed the effectiveness of a nurse-led onsite mentoring program in improving quality of care of institutional births in 24/7 primary health centres (PHCs that are open 24 hours a day, 7 days a week) of two high priority districts in Karnataka state, South India. Primary outcomes were improved facility readiness and provider preparedness in managing institutional births and associated complications during child birth. METHODS: All functional 24/7 PHCs in the two districts were included in the study. We used a parallel, cluster randomized trial design in which 54 of 108 facilities received six onsite mentoring visits, along with an initial training update and specially designed case sheets for providers; the control arm received just the initial training update and the case sheets. Pre- and post-intervention surveys were administered in April-2012 and August-2013 using facility audits, provider interviews and case sheet audits. The provider interviews were administered to all staff nurses available at the PHCs and audits were done of all the filled case sheets during the month prior to data collection. In addition, a cost analysis of the intervention was undertaken. RESULTS: Between the surveys, we achieved coverage of 100% of facilities and 91.2% of staff nurse interviews. Since the case sheets were newly designed, case-sheet audit data were available only from the end line survey for about 80.2% of all women in the intervention facilities and 57.3% in the control facilities. A higher number of facilities in the intervention arm had all appropriate drugs, equipment and supplies to deal with gestational hypertension (19 vs.3, OR (odds ratio) 9.2, 95% C.I 2.5 to33.6), postpartum haemorrhage (29 vs. 12, OR 3.7, 95% C.I 1.6 to8.3); and obstructed labour (25 vs.9, OR 3.4, 95% CI 1.6 to8.3). The providers in the intervention arm had better knowledge of active management of the third stage of labour (82.4% vs.35.8%, AOR (adjusted odds ratio) 10, 95% C.I 5.5 to 18.2); management of maternal sepsis (73.5% vs. 10.9%, AOR 36.1, 95% C.I 13.6 to 95.9); neonatal resuscitation (48.5% vs.11.7%, AOR 10.7, 95% C.I 4.6 to 25.0) and low birth weight newborn care (58.1% vs. 40.9%, AOR 2.4, 95% C.I 1.2 to 4.7). The case sheet audits revealed that providers in the intervention arm showed greater compliance with the protocols during labour monitoring (77.3% vs. 32.1%, AOR 25.8, 95% C.I 9.6 to 69.4); delivery and immediate post-partum care for mothers (78.6% vs. 31.8%, AOR 22.1, 95% C.I 8.0 to 61.4) and for newborns (73.9% vs. 32.8%, AOR 24.1, 95% C.I 8.1 to 72.0). The cost analysis showed that the intervention cost an additional $5.60 overall per delivery. CONCLUSIONS: The mentoring program successfully improved provider preparedness and facility readiness to deal with institutional births and associated complications. It is feasible to improve the quality of institutional births at a large operational scale, without substantial incremental costs. TRIAL REGISTRATION: ClinicalTrials.gov NCT02004912.

Development and evaluation of global child health educational modules.

OBJECTIVES: To determine if a standardized global child health (GCH) modular course for pediatric residents leads to satisfaction, learning, and behavior change. METHODS: Four 1-hour interactive GCH modules were developed addressing priority GCH topics. "Site champions" from 4 Canadian institutions delivered modules to pediatric residents from their respective programs during academic half-days. A pre-post, mixed methods evaluation incorporated satisfaction surveys, multiple-choice knowledge tests, and focus group discussions involving residents and satisfaction surveys from program directors. RESULTS: A total of 125 trainees participated in ≥1 module. Satisfaction levels were high. Focus group participants reported high satisfaction with the concepts taught and the dynamic, participatory approach used, which incorporated multimedia resources. Mean scores on knowledge tests increased significantly postintervention for 3 of the 4 modules (P < .001), and residents cited increases in their practical knowledge, global health awareness, and motivation to learn about global health. Program directors unanimously agreed that the modules were relevant, interesting, and could be integrated within existing formal training time. CONCLUSIONS: A relatively short, participatory, foundational GCH modular curriculum facilitated knowledge acquisition and attitude change. It could be scaled up and serve as a model for other standardized North American curricula.

Differential time to positivity: vascular catheter drawn cultures for the determination of catheter-related bloodstream infection.

BACKGROUND: Vascular access catheter-related infections are common. The purpose of this study was to evaluate the accuracy of differential time to positivity (DTP) comparing 2 blood cultures drawn through different lumens of a multi-lumen central venous catheter (CVC DTP) for the diagnosis of catheter-related bloodstream infection (CRBSI). METHODS: This study was performed at a single institution (Health Sciences Centre, Winnipeg, Manitoba, Canada). Microbiology laboratory blood culture records for the period January to November 2009 were retrospectively reviewed. All adult patients with a positive peripheral blood culture and a minimum of 2 positive central line cultures (same organism) drawn from separate lumens of a multi-lumen CVC, all obtained at the same time on the same day, were included in the study. DTP supporting CRBSI diagnosis was defined as a difference in time to positivity of ≥ 2 h between a peripheral blood culture and a CVC blood culture (peripheral DTP), or between 2 CVC blood cultures from different lumens of a multi-lumen catheter (CVC DTP). Peripheral DTP was used as the reference standard for CRBSI diagnosis. RESULTS: Thirty-five episodes of bacteremia from 33 patients were included in this study. CVC DTP had a sensitivity of 76.5% and a specificity of 88.9% for CRBSI diagnosis, using peripheral DTP as the reference standard. CONCLUSIONS: These data suggest that CVC DTP may be of benefit in the diagnosis of CRBSI. Further study is required to better define the patient population/catheter type for which CVC DTP would be of greatest benefit.

Presentation of pediatric malaria to a Canadian children's hospital.

The aim of this study was to review the aspects of malaria at a Canadian pediatric hospital and to identify gaps in management. Thirty-eight cases were diagnosed in patients with an average age of 8.4 years, the majority of which were due to Plasmodium falciparum. Two required intensive care, but survived. The majority of patients were immigrants/refugees, and accounted for almost all cases over the last 8 years of review.

Caulobacter species as a cause of postneurosurgical bacterial meningitis in a pediatric patient.

Caulobacter species have been rarely found to be a cause of human infection. A case of probable Caulobacter species meningitis occurring postneurosurgery in a pediatric patient is reported in the present article. Gram stain and colony morphology of the isolate were not consistent with the identification provided by commercial phenotypic identification systems. The present case illustrates the need to reconcile conflicting phenotypic test results using 16S ribosomal DNA sequencing.Caulobacter species have been rarely found to be a cause of human infection.

Pandemic (H1N1) 2009 influenza in hospitalized children in Manitoba: nosocomial transmission and lessons learned from the first wave.

OBJECTIVE: To review the experiences at Winnipeg Children's Hospital (WCH) during the 2009 influenza season, with an emphasis on nosocomial transmission and infection prevention and control responses. DESIGN: A case series of patients admitted to WCH who had laboratory-confirmed cases of influenza between January 1 and July 31, 2009, with a comparison of patients with seasonal influenza and those with pandemic (H1N1) 2009 influenza; a review of the impact of infection prevention and control modifications on nosocomial transmission. PATIENTS AND SETTING: A total of 104 inpatients with influenza, 81 of whom had pandemic (H1N1) 2009 influenza, were reviewed at a large Canadian pediatric tertiary care center. RESULTS: There were no differences in risk factors, presentation, or outcome between patients with seasonal influenza and those with pandemic (H1N1) 2009 influenza. There were 8 nosocomial cases of pandemic (H1N1) 2009 influenza. Excluding patients with nosocomial cases, mean length of hospital stay was significantly shortened to 3.7 days for individuals who had pandemic (H1N1) 2009 influenza and who received empiric oseltamivir on admission to the hospital, compared with 12.0 days for patients for whom treatment was delayed (P = .02). Treatment with oseltamivir of all patients with suspected cases of influenza and prompt modifications to infection control practices, including playroom closures and enhanced education of visitors and staff, terminated nosocomial transmission. CONCLUSIONS: Infection with pandemic (H1N1) 2009 influenza virus resulted in a substantial number of hospitalizations of pediatric patients in Manitoba, including those with nosocomial cases, thereby stressing the capacity of WCH. Immediate therapy with oseltamivir on admission to the hospital resulted in a significantly reduced length of hospitalization. This, coupled with intensified infection prevention and control practices, halted nosocomial transmission. These strategies should be considered in future pandemic influenza or other respiratory viral outbreaks.

CD36 deficiency attenuates experimental mycobacterial infection.

BACKGROUND: Members of the CD36 scavenger receptor family have been implicated as sensors of microbial products that mediate phagocytosis and inflammation in response to a broad range of pathogens. We investigated the role of CD36 in host response to mycobacterial infection. METHODS: Experimental Mycobacterium bovis Bacillus Calmette-Guérin (BCG) infection in Cd36+/+ and Cd36-/- mice, and in vitro co-cultivation of M. tuberculosis, BCG and M. marinum with Cd36+/+ and Cd36-/-murine macrophages. RESULTS: Using an in vivo model of BCG infection in Cd36+/+ and Cd36-/- mice, we found that mycobacterial burden in liver and spleen is reduced (83% lower peak splenic colony forming units, p < 0.001), as well as the density of granulomas, and circulating tumor necrosis factor (TNF) levels in Cd36-/- animals. Intracellular growth of all three mycobacterial species was reduced in Cd36-/- relative to wild type Cd36+/+ macrophages in vitro. This difference was not attributable to alterations in mycobacterial uptake, macrophage viability, rate of macrophage apoptosis, production of reactive oxygen and/or nitrogen species, TNF or interleukin-10. Using an in vitro model designed to recapitulate cellular events implicated in mycobacterial infection and dissemination in vivo (i.e., phagocytosis of apoptotic macrophages containing mycobacteria), we demonstrated reduced recovery of viable mycobacteria within Cd36-/- macrophages. CONCLUSIONS: Together, these data indicate that CD36 deficiency confers resistance to mycobacterial infection. This observation is best explained by reduced intracellular survival of mycobacteria in the Cd36-/- macrophage and a role for CD36 in the cellular events involved in granuloma formation that promote early bacterial expansion and dissemination.

Gastric lavage for the diagnosis of pulmonary blastomycosis in pediatric patients.

A case of pulmonary blastomycosis in a pediatric patient diagnosed by gastric lavage is described. Use of gastric lavage averted the need for more invasive diagnostic techniques including bronchoscopy. Further study is required to define the sensitivity of gastric lavage for recovery of Blastomyces dermatitidis from pediatric patients with pulmonary blastomycosis.
