Treatment of infections in young infants in low- and middle-income countries: a systematic review and meta-analysis of frontline health worker diagnosis and antibiotic access.

BACKGROUND: Inadequate illness recognition and access to antibiotics contribute to high case fatality from infections in young infants (<2 months) in low- and middle-income countries (LMICs). We aimed to address three questions regarding access to treatment for young infant infections in LMICs: (1) Can frontline health workers accurately diagnose possible bacterial infection (pBI)?; (2) How available and affordable are antibiotics?; (3) How often are antibiotics procured without a prescription? METHODS AND FINDINGS: We searched PubMed, Embase, WHO/Health Action International (HAI), databases, service provision assessments (SPAs), Demographic and Health Surveys, Multiple Indicator Cluster Surveys, and grey literature with no date restriction until May 2014. Data were identified from 37 published studies, 46 HAI national surveys, and eight SPAs. For study question 1, meta-analysis showed that clinical sign-based algorithms predicted bacterial infection in young infants with high sensitivity (87%, 95% CI 82%-91%) and lower specificity (62%, 95% CI 48%-75%) (six studies, n = 14,254). Frontline health workers diagnosed pBI in young infants with an average sensitivity of 82% (95% CI 76%-88%) and specificity of 69% (95% CI 54%-83%) (eight studies, n = 11,857) compared to physicians. For question 2, first-line injectable agents (ampicillin, gentamicin, and penicillin) had low variable availability in first-level health facilities in Africa and South Asia. Oral amoxicillin and cotrimoxazole were widely available at low cost in most regions. For question 3, no studies on young infants were identified, however 25% of pediatric antibiotic purchases in LMICs were obtained without a prescription (11 studies, 95% CI 18%-34%), with lower rates among infants <1 year. Study limitations included potential selection bias and lack of neonatal-specific data. CONCLUSIONS: Trained frontline health workers may screen for pBI in young infants with relatively high sensitivity and lower specificity. Availability of first-line injectable antibiotics appears low in many health facilities in Africa and Asia. Improved data and advocacy are needed to increase the availability and appropriate utilization of antibiotics for young infant infections in LMICs.

Patterns of pediatric injury in South Africa: an analysis of hospital data between 1997 and 2006.

BACKGROUND: Pediatric injuries are associated with significant morbidity and mortality, especially in low- and middle-income countries. Despite the magnitude of this burden, there is lack of data to characterize the etiology and risk factors associated with childhood injuries, especially in low- and middle-income countries. The aim of this article is to describe the demographics, mechanisms, and severity of injuries during a 10-year time period using hospital-based data in Cape Town, South Africa. METHODS: Data from Childsafe South Africa's registry were used to study injured children younger than 13 years who presented with either intentional or unintentional injuries to the Trauma Unit of the Red Cross War Memorial Children's Hospital's (RCH) Causality Department between 1996 and 2007. Univariate and bivariate analyses were performed for demographic characteristics and injury mechanisms. Poisson regression analysis was used to analyze the age-adjusted annual incidence of injury presenting to RCH. RESULTS: Between 1997 and 2006, 62,782 children with a total of 68,883 injuries presented to RCH. The mean age was 5.4 years (standard deviation ± 3.5 years) and 61.7% were male. Mechanism of injury included falls (39.8%), road traffic injuries (15.7%), burns (8.8%), and assault (7.4%). The majority of injuries occurred in and around the home. Abbreviated injury severity scoring showed 60.2% of injuries were minor, 36.6% were moderate, and 3.2% were severe. Sixty-six deaths occurred in the trauma casualty department. Thirty-one percent of patients were admitted to the hospital; children who suffered burn and head injuries were more likely to require admission. CONCLUSION: Age, gender, mechanism, and severity of injury in pediatric populations have not been described elsewhere in South African national or sub-Saharan regional data. This retrospective, observational study uses Level II evidence to suggest the need for targeted interventions to address risk factors for pediatric injuries, emphasizing the importance of pediatric surveillance systems as a tool to study injuries in developing countries. LEVEL OF EVIDENCE: Prognostic study, level II.

Care seeking for neonatal illness in low- and middle-income countries: a systematic review.

BACKGROUND: Despite recent achievements to reduce child mortality, neonatal deaths continue to remain high, accounting for 41% of all deaths in children under five years of age worldwide, of which over 90% occur in low- and middle-income countries (LMICs). Infections are a leading cause of death and limitations in care seeking for ill neonates contribute to high mortality rates. As estimates for care-seeking behaviors in LMICs have not been studied, this review describes care seeking for neonatal illnesses in LMICs, with particular attention to type of care sought. METHODS AND FINDINGS: We conducted a systematic literature review of studies that reported the proportion of caregivers that sought care for ill or suspected ill neonates in LMICs. The initial search yielded 784 studies, of which 22 studies described relevant data from community household surveys, facility-based surveys, and intervention trials. The majority of studies were from South Asia (n = 17/22), set in rural areas (n = 17/22), and published within the last 4 years (n = 18/22). Of the 9,098 neonates who were ill or suspected to be ill, 4,320 caregivers sought some type of care, including care from a health facility (n = 370) or provider (n = 1,813). Care seeking ranged between 10% and 100% among caregivers with a median of 59%. Care seeking from a health care provider yielded a similar range and median, while care seeking at a health care facility ranged between 1% and 100%, with a median of 20%. Care-seeking estimates were limited by the few studies conducted in urban settings and regions other than South Asia. There was a lack of consistency regarding illness, care-seeking, and care provider definitions. CONCLUSIONS: There is a paucity of data regarding newborn care-seeking behaviors; in South Asia, care seeking is low for newborn illness, especially in terms of care sought from health care facilities and medically trained providers. There is a need for representative data to describe care-seeking patterns in different geographic regions and better understand mechanisms to enhance care seeking during this vulnerable time period.

Road traffic injuries in Kenya: the health burden and risk factors in two districts.

BACKGROUND: Road traffic injuries (RTIs) contribute to a significant proportion of the burden of disease in Kenya. They also have a significant impact on the social and economic well-being of individuals, their families, and society. However, though estimates quantifying the burden of RTIs in Kenya do exist, most of these studies date back to the early 2000s-more than one decade ago. OBJECTIVE: This article aims to present the current status of road safety in Kenya. Using data from the police and vital registration systems in Kenya, we present the current epidemiology of RTIs in the nation. We also sought to assess the status of 3 well-known risk factors for RTIs-speeding and the use of helmets and reflective clothing. METHODS: Data for this study were collected in 2 steps. The first step involved the collection of secondary data from the Kenya traffic police as well as the National Vital Registration System to assess the current trends of RTIs in Kenya. Following this, observational studies were conducted in the Thika and Naivasha districts in Kenya to assess the current status of speeding among all vehicles and the use of helmets and reflective clothing among motorcyclists. RESULTS: The overall RTI rate in Kenya was 59.96 per 100,000 population in 2009, with vehicle passengers being the most affected. Notably, injuries to motorcyclists increased at an annual rate of approximately 29 percent (95% confidence interval [CI]: 27-32; P < .001). The mean age of death due to road traffic crashes was 35 years. Fatalities due to RTIs increased at an annual rate of 7 percent (95% CI: 6-8; P < .001) for the period 2004 to 2009. Observational studies revealed that 69.45 percent of vehicles in Thika and 34.32 percent of vehicles in Naivasha were speeding. Helmets were used by less than one third of motorcycle drivers in both study districts, with prevalence rates ranging between 3 and 4 percent among passengers. CONCLUSIONS: This study highlights the significant burden of RTIs in Kenya. A renewed focus on addressing this burden is necessary. Focusing on increasing helmet and reflective clothing use and enforcement of speed limits has the potential to prevent a large number of road traffic crashes, injuries, and fatalities. However, it is difficult to demonstrate the magnitude of the injury problem to policymakers with minimal or inaccurate data, and this study illustrates the need for national continuous, systematic, and sustainable data collection efforts, echoing similar calls for action throughout the injury literature.

Unintentional injuries: magnitude, prevention, and control.

The World Health Organization estimates injuries accounted for more than 5 million deaths in 2004, significantly impacting the global burden of disease. Nearly 3.9 million of these deaths were due to unintentional injury, a cause also responsible for more than 138 million disability-adjusted life years (DALYs) lost in the same year. More than 90% of the DALYs lost occur in low- and middle-income countries (LMICs), highlighting the disproportionate burden that injuries place on developing countries. This article examines the health and social impact of injury, injury data availability, and injury prevention interventions. By proposing initiatives to minimize the magnitude of death and disability due to unintentional injuries, particularly in LMICs, this review serves as a call to action for further investment in injury surveillance, prevention interventions, and health systems strengthening.

Assessment of the proportion of neonates and children in low and middle income countries with access to a healthcare facility: A systematic review.

BACKGROUND: Comprehensive antenatal, perinatal and early postnatal care has the potential to significantly reduce the 3.58 million neonatal deaths that occur annually worldwide. This paper systematically reviews data on the proportion of neonates and children < 5 years of age that have access to health facilities in low and middle income countries. Gaps in available data by WHO region are identified, and an agenda for future research and advocacy is proposed. METHODS: For this paper, "utilization" was used as a proxy for "access" to a healthcare facility, and the term "facility" was used for any clinic or hospital outside of a person's home staffed by a "medical professional". A systematic literature search was conducted for published studies of children up to 5 years of age that included the neonatal age group with an illness or illness symptoms in which health facility utilization was quantified. In addition, information from available Demographic and Health Surveys (DHS) was extracted. RESULTS: The initial broad search yielded 2,239 articles, of which 14 presented relevant data. From the community-based neonatal studies conducted in the Southeast Asia region with the goal of enhancing care-seeking for neonates with sepsis, the 10-48% of sick neonates in the studies' control arms utilized a healthcare facility. Data from cross-sectional surveys involving young children indicate that 12 to 86% utilizing healthcare facilities when sick. From the DHS surveys, a global median of 58.1% of infants < 6 months were taken to a facility for symptoms of ARI. CONCLUSIONS: There is a scarcity of data regarding the access to facility-based care for sick neonates/young children in many areas of the world; it was not possible to generalize an overall number of neonates or young children that utilize a healthcare facility when showing signs and symptoms of illness. The estimate ranges were broad, and there was a paucity of data from some regions. It is imperative that researchers, advocates, and policy makers join together to better understand the factors affecting health care utilization/access for newborns in different settings and what the barriers are that prevent children from being taken to a facility in a timely manner.

Global health: injuries and violence.

Injury and violence rank among the leading causes of death worldwide, with more than 5 million deaths annually, representing a significant portion of the global burden of disease. This article examines how injury and violence relate to global health using recent global burden of disease data and selected key studies and databases, and further explores risk factors and intervention initiatives that address unintentional and intentional injuries. The article serves as a call to action to enhance understanding of the growing burden of injury and violence, especially in low-income and middle-income countries, where more than 90% of injuries occur.

Lactate in trauma: a poor predictor of mortality in the setting of alcohol ingestion.

Resuscitation end point markers such as lactate and base deficit (BD) are used in trauma to identify and treat a state of compensated shock. Lactate and BD levels are also elevated by alcohol. In blunt trauma patients with positive blood alcohol levels, lactate may be a poor indicator of injury. Retrospective data were collected on 1083 blunt trauma patients with positive blood alcohol levels admitted a Level I trauma center between 2003 and 2006. Patients were stratified by Injury Severity Score, age, gender, and Glasgow Coma Score. Logistic regression analyses were used to assess lactate and BD as independent risk factors for mortality. Seventy-four per cent of patients had an abnormal lactate level compared with 28 per cent with abnormal BD levels. In patients with mild injury, lactate levels were abnormal in more than 70 per cent of patients compared with less than 20 per cent of patients with abnormal BD levels. Linear regression showed lactate is not a significant predictor of mortality. Regardless of Injury Severity Score, lactate appeared to be more often abnormal than BD in the setting of alcohol ingestion. Additionally, because BD, and not lactate, was shown to be an independent predictor of mortality, lactate may not be a reliable marker of end point resuscitation in this patient population.

The epidemiology of road traffic injuries in the Republic of Lithuania, 1998-2007.

BACKGROUND: This article highlights the epidemiology of road traffic injury (RTI) in Lithuania between 1998 and 2007. The purpose of this study is to explore the incidence of RTI, age-standardized mortality rates (ASMR), gender-specific rates and the RTI profile of different user groups. In doing so, this analysis attempts to emphasize the need for RTI prevention policies and programmes. METHODS: Six databases were analysed using ICD-10 codes V01-V99, pertaining to the causes of road traffic crashes. Data between 1998 and 2007 were obtained from these databases to identify and calculate RTI incidence and mortality rates. This was then analysed with regard to ASMR, gender, user groups and the use of alcohol. RESULTS: In 2007, RTI incidence in Lithuania was reported as 270/100,000 people, 10.7% higher than in 1998. ASMR declined from 28 deaths per 100,000 in 1998 to 25 deaths per 100,000 in 2007. Between 1998 and 2007, the male ASMR declined from 46 to 40 deaths per 100,000 and the female ASMR decreased from 13 to 11 deaths per 100,000. Car occupant and pedestrian fatalities comprised 87% of all RTI deaths. Thirty-four percent of those injured and 21% of the dead were under influence of alcohol. CONCLUSIONS: From 1998 to 2007, the incidence of RTI has worsened and mortality rates remain high in Lithuania. Alcohol remains a prominent risk factor of traffic injury and death. The need to develop effective prevention programmes to address traffic injury is essential.
