Neonatal morbidity and mortality in a Tanzanian tertiary care referral hospital

Bacterial Aetiology of Neonatal Sepsis and Antimicrobial Resistance Pattern at the Regional Referral Hospital, Dar es Salam, Tanzania; A Call to Strengthening Antibiotic Stewardship Program

The diagnosis of neonatal sepsis in lower-income countries is mainly based on clinical presentation. The practice necessitates empirical treatment with limited aetiology and antibiotic susceptibility profile knowledge, prompting the emergence and spread of antimicrobial resistance. We conducted a cross-sectional study to determine the aetiology of neonatal sepsis and antimicrobial resistance patterns. We recruited 658 neonates admitted to the neonatal ward with signs and symptoms of sepsis and performed 639 automated blood cultures and antimicrobial susceptibility testing. Around 72% of the samples were culture positive; Gram-positive bacteria were predominantly isolated, contributing to 81%. Coagulase-negative Staphylococci were the most isolates, followed by Streptococcus agalactiae. Overall, antibiotic resistance among Gram-positive pathogens ranged from 23% (Chloramphenicol) to 93% (Penicillin) and from 24.7% (amikacin) to 91% (ampicillin) for Gram-negative bacteria. Moreover, about 69% of Gram-positive and 75% of Gram-negative bacteria were multidrug-resistant (MDR). We observed about 70% overall proportion of MDR strains, non-significantly more in Gram-negative than Gram-positive pathogens (p = 0.334). In conclusion, the pathogen causing neonatal sepsis in our setting exhibited a high resistance rate to commonly used antibiotics. The high rate of MDR pathogens calls for strengthening antibiotic stewardship programs.

Appraising Neonatal Morbidity and Mortality in a Developing Country Categorized by Gestational Age Grouping and Implications for Targeted Interventions

Introduction

Despite the relatively higher neonatal morbidity and mortality in developing countries, there are limited data on the detailed analysis of the burden in Nigeria. With a database of over 14,000 admissions, this study presents a compelling picture of the current trends disaggregated by their gestational age groups. It provides unique opportunities for better-targeted interventions for further reducing newborn mortality in line with SDG 3, Target 3.2.

Methods

This prospective observational study involved newborn babies admitted to the Neonatal Intensive Care Unit of the University of Ilorin Teaching Hospital, Kwara State, Nigeria, between January 2007 and December 2018. The outcome was the neonatal mortality rates. The exposure variables included birth weight, gestational age (preterm versus term), and clinical diagnosis. Frequencies were generated on tables and charts, and the trends or associations were determined.

Results

Of the 14,760 neonates admitted, 9,030 (61.2%) were term babies, 4,847 (32.8%) were preterm babies, and in 792 (5%) of the admissions, the gestational ages could not be determined. Males constituted a higher proportion with 55.9%, and the total number of deaths in the study period was 14.7%. The mortality ratio was highest among babies with a birth weight of less than 1,000 g (38.0%) and gestational age of less than 28 weeks (65.5%). The trend analysis showed that the mortality rate decreased from 17.8 to 13% over the 12 years, p-value < 0.0001. For term babies, mortality decreased by 45%, from 15.7% in 2007 to 8.7% in 2018, while the decline in mortality for preterm babies was 28.4%, from 25.7% in 2007 to 18.4% in 2018. For both categories, p-values were < 0.001. Regarding morbidity in term babies, asphyxia occurred in (1:3), jaundice (1:5), sepsis (1:6), and respiratory disorders (1:6) of admissions. For mortality, asphyxia occurred in (1:2), sepsis (1:5), jaundice (1:8), and respiratory disorders (1:10) of deaths. The leading causes of morbidity among preterm babies were asphyxia (1:4), sepsis (1:5), respiratory disorders (1:9), and jaundice (1.10). For mortality, their contributions were asphyxia (≈1:2); sepsis (1:5); respiratory disorders (1:9), and jaundice (1:10).

Conclusion

There was a marked improvement in neonatal mortality trends. However, severe perinatal asphyxia, sepsis, hyperbilirubinemia, and respiratory disorders were the leading conditions contributing to 75% of the morbidities and mortalities. Measures to further accelerate the reduction in neonatal morbidity and mortality are discussed.

Colonization Rate of Potential Neonatal Disease-Causing Bacteria, Associated Factors, and Antimicrobial Susceptibility Profile Among Pregnant Women Attending Government Hospitals in Hawassa, Ethiopia

Introduction

Vaginal colonization with some species of bacteria during the last term of pregnancy can affect the health of fetuses and newborns resulting in high morbidity and mortality among newborns.

Objective

The aim of this study was to determine the colonization rate of potential neonatal disease-causing bacteria, factors associated with colonization rate, and the antimicrobial susceptibility profile of bacteria among pregnant women.

Methods

Institution-based cross-sectional study was conducted on pregnant women from October 13 to December 28, 2020, at government hospitals located in Hawassa, Ethiopia. Background data were captured using a structured questionnaire. Vaginal swabs were collected to isolate bacteria using the standard method. Antimicrobial susceptibility test was performed using the modified Kirby–Bauer disc diffusion method. Data were analyzed using SPSS. Factors that could predict vaginal colonization with potential neonatal disease-causing bacteria were determined using logistic regression.

Results

Overall bacterial colonization rate among pregnant women was 271 (98.9%) 95 CI (97.4‒100.1). The prevalence of potential neonatal disease-causing bacteria was 95 (34.7%) 95 CI (28.8‒40.1). The proportion of potential neonatal disease-causing bacteria were as follows: Escherichia coli (n=82, 29.9%), Acinetobacter species (n=9, 3.3%), Staphylococcus aureus (n=7. 2.6%), and Klebsiella pneumoniae (n=4, 1.5%). Pregnant women with a gestational age of 38‒40 weeks were 1.9 times (AOR= 1.9, 95% CI= 1.0–3.4, p=0.04) were more likely to be colonized by potential neonatal disease-causing bacteria. All E. coli, Klebsiella species, and Acinetobacter species were susceptible to gentamicin and imipenem. All S. aureus were susceptible to penicillin, tetracycline, clindamycin, and erythromycin.

Conclusion

High proportion of pregnant women in this study were colonized with potential neonatal disease-causing bacteria. E. coli was the predominant bacteria. Most bacteria isolated in this study were susceptible to antimicrobial agents tested. Gestational age was significantly associated with the colonization rate of potential neonatal disease-causing bacteria.

Surveillance for incidence and etiology of early-onset neonatal sepsis in Soweto, South Africa

BACKGROUND

Globally, over 400,000 neonatal deaths in 2015 were attributed to sepsis, however, the incidence and etiologies of these infections are largely unknown in low-middle income countries. We aimed to determine incidence and etiology of community-acquired early-onset (<72 hours age) sepsis (EOS) using culture and molecular diagnostics.

METHODS

This was a prospective observational study, in which we conducted a surveillance for pathogens using a combination of blood culture and a polymerase chain reaction (PCR)-based test. Blood culture was performed on all neonates with suspected EOS. Among the subset fulfilling criteria for protocol-defined EOS, blood and nasopharyngeal (NP) respiratory swabs were tested by quantitative real-time reverse-transcriptase PCR using a Taqman Array Card (TAC) with 15 bacterial and 12 viral targets. Blood and NP samples from 312 healthy newborns were also tested by TAC to estimate background positivity rates. We used variant latent-class methods to attribute etiologies and calculate pathogen-specific proportions and incidence rates.

RESULTS

We enrolled 2,624 neonates with suspected EOS and from these 1,231 newborns met criteria for protocol-defined EOS (incidence- 39.3/1,000 live-births). Using the partially latent-class modelling, only 26.7% cases with protocol-defined EOS had attributable etiology, and the largest pathogen proportion were Ureaplasma spp. (5.4%; 95%CI: 3.6-8.0) and group B Streptococcus (GBS) (4.8%; 95%CI: 4.1-5.8), and no etiology was attributable for 73.3% of cases. Blood cultures were positive in 99/1,231 (8.0%) with protocol-defined EOS (incidence- 3.2/1,000 live-births). Leading pathogens on blood culture included GBS (35%) and viridans streptococci (24%). Ureaplasma spp. was the most common organism identified on TAC among cases with protocol-defined EOS.

CONCLUSION

Using a combination of blood culture and a PCR-based test the common pathogens isolated in neonates with sepsis were Ureaplasma spp. and GBS. Despite documenting higher rates of protocol-defined EOS and using a combination of tests, the etiology for EOS remains elusive.

Causes of Morbidity and Mortality among Neonates and Children in Post-Conflict Burundi: A Cross-Sectional Retrospective Study

The risk of a child dying before age five in Burundi is almost 1.6 times higher than that in the World Health Organization (WHO) African region. However, variations in the all-cause mortality rates across Burundi have not yet been measured directly at subnational levels, age group and by gender. The objective of this study was to describe the main causes of hospitalization and mortality in children during the neonatal period and at ages 1 to 59 months, for boys and girls, and to assess the total annual (2010) burden of under-five morbidity and mortality in hospitals using hospitalization records from 21 district hospitals. We found variation in the gender and regional distribution of the five leading causes of hospitalization and death of children under five. Although the five causes accounted for 89% (468/523) of all neonatal hospitalizations, three causes accounted for 93% (10,851/11,632) of all-cause hospitalizations for children ages 1 to 59 months (malaria, lung disease, and acute diarrhea), malaria accounted for 69% (1086/1566) of all deaths at ages 1 to 59 months. In Burundi, human malarial infections continue to be the main cause of hospitalization and mortality among under-five children.

Relevant analyses of pathogenic bacteria and inflammatory factors in neonatal purulent meningitis

Pathogenic bacteria and inflammatory factors in neonatal purulent meningitis (PM) were investigated to explore the diagnostic value of inflammatory factors in PM, to clarify the etiology, and to provide evidence for rational clinical treatment. Seventy-four neonates who were diagnosed with PM and were bacteriogically positive in Daqing Longnan Hospital from January 2012 to December 2015 were retrospectively analyzed and used as observation group. Another 74 neonates simultaneously hospitalized with non-PM factors were selected as control group. The levels of C-reactive protein (CRP) and β 2 microglobulin (β2MG) in cerebrospinal fluid in pediatric patients were measured, and the separation culture and identification of pathogenic bacteria were carried out at the same time. The results showed that i) neonatal PM often lacked specific clinical manifestations; ii) high risk factors of neonatal PM included gestational age, body weight <2,500 g, neonatal asphyxia, premature rupture of membranes, and umbilical or pulmonary infection; iii) the levels of CRP and β2MG in the cerebrospinal fluid in the neonatal PM group were significantly higher than those in the control group (P<0.05), and the neonatal PM group had obviously decreased levels of CRP and β2MG in the cerebrospinal fluid after treatment compared with those before treatment (P<0.05); iv) the positive rate of Gram-negative bacilli (G-bacilli) showed an increasing trend year by year in the past 4 years. Seventy-four strains of bacteria were isolated from the cerebrospinal fluid in neonatal PM group, including 45 strains of Gram-positive cocci (G+cocci, accounting for 60.81%) and 29 strains of G-bacilli (accounting for 39.19%). Among them, the top three were Escherichia coli, coagulase-negative staphylococci (CNS) and Streptococcus. These findings indicated that for suspected PM pediatric patients with high risk factors, the inflammatory factors in cerebrospinal fluid and the etiology should be investigated via lumbar puncture as early as possible to confirm the diagnosis. Pathogenic bacteria of meningitis mainly are Escherichia coli, CNS and Streptococcus, and the characteristics of pathogenic bacteria should be considered during experiential medication. The incidence rate of PM due to Streptococcus has an upward tendency and great damage, needing to arouse high attention in clinic.

Where technology does not go: specialised neonatal care in resource-poor and conflict-affected contexts

Setting: Although neonatal mortality is gradually decreasing worldwide, 98% of neonatal deaths occur in low- and middle-income countries, where hospital care for sick and premature neonates is often unavailable. Médecins Sans Frontières Operational Centre Brussels (MSF-OCB) managed eight specialised neonatal care units (SNCUs) at district level in low-resource and conflict-affected settings in seven countries. Objective: To assess the performance of the MSF SNCU model across different settings in Africa and Southern Asia, and to describe the set-up of eight SNCUs, neonate characteristics and clinical outcomes among neonates from 2012 to 2015. Design: Multicentric descriptive study. Results: The MSF SNCU model was characterised by an absence of high-tech equipment and an emphasis on dedicated nursing and medical care. Focus was on the management of hypothermia, hypoglycaemia, feeding support and early identification/treatment of infection. Overall, 11 970 neonates were admitted, 41% of whom had low birthweight (<2500 g). The main diagnoses were low birthweight, asphyxia and neonatal infections. Overall mortality was 17%, with consistency across the sites. Chances of survival increased with higher birthweight. Conclusion: The standardised SNCU model was implemented across different contexts and showed in-patient outcomes within acceptable limits. Low-tech medical care for sick and premature neonates can and should be implemented at district hospital level in low-resource settings.

Improved Neonatal Mortality at a District Hospital in Aweil, South Sudan

Neonatal deaths comprise a growing proportion of global under-five mortality. However, data from the highest-burden areas is sparse. This descriptive retrospective study analyses the outcomes of all infants exiting the Médecins sans Frontières-managed neonatal unit in Aweil Hospital, rural South Sudan from 2011 to 2014. A total of 4268 patients were treated over 4 years, with annual admissions increasing from 687 to 1494. Overall mortality was 13.5% (n = 576), declining from 18.7% to 11.1% (p for trend <0.001). Newborns weighing <2500 g were at significantly increased mortality risk compared with babies ≥2500 g (odds ratio = 2.27, 95% confidence interval = 1.9-2.71, p < 0.001). Leading causes of death included sepsis (49.7%), tetanus (15.8%), respiratory distress (12.8%) and asphyxia (9.2%). Tetanus had the highest case fatality rate (49.7%), followed by perinatal asphyxia (26.5%), respiratory distress (20.4%) and neonatal sepsis (10.5%). Despite increasing admissions, overall mortality declined, indicating that survival of these especially vulnerable infants can be improved even in a basic-level district hospital programme.

Is facility based neonatal care in low resource setting keeping pace? A glance at Uganda's National Referral Hospital

OBJECTIVES

To identify reasons for neonatal admission and death with the aim of determining areas needing improvement.

METHOD

A retrospective chart review was conducted on records for neonates admitted to Mulago National Referral Hospital Special Care Baby Unit (SCBU) from 1(st) November 2013 to 31(st) January 2014. Final diagnosis was generated after analyzing sequence of clinical course by 2 paediatricians.

RESULTS

A total of 1192 neonates were admitted. Majority 83.3% were in-born. Main reasons for admissions were prematurity (37.7%) and low APGAR (27.9%).Overall mortality was 22.1% (Out-born 33.6%; in born 19.8%). Half (52%) of these deaths occurred in the first 24 hours of admission. Major contributors to mortality were prematurity with hypothermia and respiratory distress (33.7%) followed by birth asphyxia with HIE grade III (24.6%) and presumed sepsis (8.7%). Majority of stable at risk neonates 318/330 (i.e. low APGAR or prematurity without comorbidity) survived. Factors independently associated with death included gestational age <30 weeks (p 0.002), birth weight <1500g (p 0.007) and a 5 minute APGAR score of < 7 (p 0.001). Neither place of birth nor delayed and after hour admissions were independently associated with mortality.

CONCLUSION AND RECOMMENDATIONS

Mortality rate in SCBU is high. Prematurity and its complications were major contributors to mortality. The management of hypothermia and respiratory distress needs scaling up. A step down unit for monitoring stable at risk neonates is needed in order to decongest SCBU.

Predictors of Hospitalization During the First Year of Life among 31999 Tanzanian Infants

OBJECTIVE

This study explored the risk factors for infant hospitalization in urban and peri-urban/rural Tanzania.

METHODS

We conducted a prospective cohort study examining predictors of hospitalization during the first year of life among infants enrolled at birth in a large randomized controlled trial of neonatal vitamin A supplementation conducted in urban Dar es Salaam (n = 11,895) and peri-urban/rural Morogoro region (n = 20,104) in Tanzania. Demographic, socioeconomic, environmental and birth outcome predictors of hospitalization were assessed using proportional hazard models.

RESULTS

The rate of hospitalization was highest during the neonatal period in both Dar es Salaam (102/10,000 neonatal-months) and Morogoro region (78/10,000 neonatal-months). Hospitalization declined with increased age and was lowest for infants 6-12 months of age in both Dar es Salaam (11/10,000 infant-months) and Morogoro region (16/10,000 infant-months). In both Dar es Salaam and Morogoro region, older maternal age, male sex, low birth weight and being small for gestational age were significant predictors of higher risk of hospitalization (p < 0.05). Increased wealth and having a flush toilet were significantly associated with an increased risk of hospitalization in Morogoro region only (p < 0.05).

CONCLUSIONS

This study determined high rates of neonatal hospitalization in Tanzania. Interventions to increase birth size may decrease risk of hospitalization. Equity in access to hospitals for poor rural families in Tanzania requires attention.

Characteristics and mortality of neonates in an emergency obstetric and neonatal care facility, rural Burundi

SETTING

A Médecins Sans Frontières emergency obstetric and neonatal care facility specialising as a referral centre for three districts for women with complications during pregnancy or delivery in rural Burundi.

OBJECTIVE

To describe the characteristics and in-facility mortality rates of neonates born in 2011.

DESIGN

Descriptive study involving a retrospective review of routinely collected facility data.

RESULTS

Of 2285 women who delivered, the main complications were prolonged labour 331 (14%), arrested labour 238 (10%), previous uterine intervention 203 (9%), breech 171 (8%) and multiple gestations 150 (7%). There were 175 stillbirths and 2110 live neonates, of whom 515 (24%) were of low birth weight, 963 (46%) were delivered through caesarean section and 267 (13%) required active birth resuscitation. Overall, there were 102 (5%) neonatal deaths. A total of 453 (21%) neonates were admitted to dedicated neonatal special services for sick and low birth weight babies. A high proportion of these neonates were delivered by caesarean section and needed active birth resuscitation. Of 67 (15%) neonatal deaths in special services, 85% were due to conditions linked to low birth weight and birth asphyxia.

CONCLUSION

Among neonates born to women with complications during pregnancy or delivery, in-facility deaths due to low birth weight and birth asphyxia were considerable. Sustained attention is needed to reduce these mortality rates.

Risk Factors for Preterm Birth among HIV-Infected Tanzanian Women: A Prospective Study

Premature delivery, a significant cause of child mortality and morbidity worldwide, is particularly prevalent in the developing world. As HIV is highly prevalent in much of sub-Saharan Africa, it is important to determine risk factors for prematurity among HIV-positive pregnancies. The aims of this study were to identify risk factors of preterm (<37 weeks) and very preterm (<34 weeks) birth among a cohort of 927 HIV positive women living in Dar es Salaam, Tanzania, who enrolled in the Tanzania Vitamin and HIV Infection Trial between 1995 and 1997. Multivariable relative risk regression models were used to determine the association of potential maternal risk factors with premature and very premature delivery. High rates of preterm (24%) and very preterm birth (9%) were found. Risk factors (adjusted RR (95% CI)) for preterm birth were mother <20 years (1.46 (1.10, 1.95)), maternal illiteracy (1.54 (1.10, 2.16)), malaria (1.42 (1.11, 1.81)), Entamoeba coli (1.49 (1.04, 2.15)), no or low pregnancy weight gain, and HIV disease stage ≥2 (1.41 (1.12, 1.50)). Interventions to reduce pregnancies in women under 20, prevent and treat malaria, reduce Entamoeba coli infection, and promote weight gain in pregnant women may have a protective effect on prematurity.

Demographics, clinical characteristics and neonatal outcomes in a rural Ugandan NICU

Background

Ninety-six percent of the world’s 3 million neonatal deaths occur in developing countries where the majority of births occur outside of a facility. Community-based approaches to the identification and management of neonatal illness have reduced neonatal mortality over the last decade. To further expand life-saving services, improvements in access to quality facility-based neonatal care are required. Evaluation of rural neonatal intensive care unit referral centers provides opportunities to further understand determinants of neonatal mortality in developing countries. Our objective was to describe demographics, clinical characteristics and outcomes from a rural neonatal intensive care unit (NICU) in central Uganda from 2005–2008.

Methods

The NICU at Kiwoko hospital serves as a referral center for three rural districts of central Uganda. For this cross sectional study we utilized a NICU clinical database that included admission information, demographics, and variables related to hospital course and discharge. Descriptive statistics are reported for all neonates (<28 days old) admitted to the NICU between December 2005 and September 2008, disaggregated by place of birth. Percentages reported are among neonates for which data on that indicator were available.

Results

There were 809 neonates admitted during the study period, 68% (490/717) of whom were inborn. The most common admission diagnoses were infection (30%, 208/699), prematurity (30%, 206/699), respiratory distress (28%, 198/699) and asphyxia (22%, 154/699). Survival to discharge was 78% (578/745). Mortality was inversely proportional to birthweight and gestational age (P-value test for trend <0.01). This was true for both inborn and outborn infants (p < 0.01). Outborn infants were more likely to be preterm (44%, (86/192) vs. 33%, (130/400), P-value <0.01) and to be low birthweight (58%, (101/173) vs. 40%, (190/479), P-value <0.01) than inborn infants. Outborn neonates had almost twice the mortality (33%, 68/208) as inborn neonates (17%, 77/456) (P-value <0.01).

Conclusions

Understanding determinants of neonatal survival in facilities is important for targeting improvements in facility based neonatal care and increasing survival in low and middle income countries.

The effects of standardised protocols of obstetric and neonatal care on perinatal and early neonatal mortality at a rural hospital in Tanzania

The care of pregnant women and neonates in peripheral hospitals in many developing countries is in a critical state. Through a retrospective analysis we assessed the effects of the introduction of standardised protocols in obstetric and neonatal care (implementation from 1998 onwards) on perinatal and neonatal outcomes of all deliveries over seven years (1996-2002) at a first-referral hospital in rural Tanzania. In all, there were 18 026 deliveries (18 316 live births and 606 stillbirths). Perinatal mortality rates (PMR) varied from 42.8-54.5/1000 live births during the years. Early neonatal mortality rates (eNMR) fell from 21.9/1000 live births in 1996 to 14.8/1000 live births in 2002 (all p > 0.05). Fresh stillbirth rates decreased over time (p = 0.041), however macerated stillbirth rates increased during the second half of the period (p = 0.067). Sixty-two to seventy-two percent of eNMR occurred on the first day of life (p < 0.001). Maternal mortality ratio declined from 729/100 000 live births in 1996 to 119/100 000 live births in 2002 (p = 0.002). Our clinical project was associated with a reduction of PMR and eNMR (and maternal mortality ratios), but with considerable fluctuations during the years. Improving obstetric and neonatal care in the hospital setting in developing countries is essential, but needs long-term commitment and support.

A descriptive study of perinatal asphyxia at the University Hospital of Kinshasa (Democratic Republic of Congo)

BACKGROUND

Perinatal asphyxia is the third cause of neonatal death after prematurity and infection.

OBJECTIVE

The purpose of this study was to determine the incidence, the etiology and the HIE score at the first day in term and near-term newborns with perinatal asphyxia at the University Hospital of Kinshasa.

METHODS

50 term and near-term neonates with perinatal asphyxia were studied prospectively after they were admitted in neonatal intensive care from November 2009 to January 2011. For each patient admitted the perinatal data were collected. Clinical assessment was performed by the Sarnat grading and the Thompson score within twenty-four hours. Medcalc® was used for statistics.

RESULTS

50 babies were scored. The median maternal age was 31 years. In 22% of the mothers preeclampsia was diagnosed. Urogenital infection, IUGR were other prenatal diagnoses. Median Apgar score was 4 after 1 minute, 5 after 5 minutes and 6 after 10 minutes. Sarnat grade 1 was seen in 16 patients, Sarnat grade 2 in 20 patients and grade 3 in 8. Thompson score in the first 24 hours was more than 7 in 60% of the patients. A good correlation was found between the Thompson score and the Sarnat grade (r: 0,77; p < 0,0001). 14 of the 50 babies died. Both Sarnat and Thompson score correlated significantly with mortality.

CONCLUSION

The incidence of perinatal asphyxia at the University Hospital of Kinshasa remains high and the majority of patients had a severe HIE.

A rapid assessment of the quality of neonatal healthcare in Kilimanjaro region, northeast Tanzania

BACKGROUND

While child mortality is declining in Africa there has been no evidence of a comparable reduction in neonatal mortality. The quality of inpatient neonatal care is likely a contributing factor but data from resource limited settings are few. The objective of this study was to assess the quality of neonatal care in the district hospitals of the Kilimanjaro region of Tanzania.

METHODS

Clinical records were reviewed for ill or premature neonates admitted to 13 inpatient health facilities in the Kilimanjaro region; staffing and equipment levels were also assessed.

RESULTS

Among the 82 neonates reviewed, key health information was missing from a substantial proportion of records: on maternal antenatal cards, blood group was recorded for 52 (63.4%) mothers, Rhesus (Rh) factor for 39 (47.6%), VDRL for 59 (71.9%) and HIV status for 77 (93.1%). From neonatal clinical records, heart rate was recorded for3 (3.7%) neonates, respiratory rate in 14, (17.1%) and temperature in 33 (40.2%). None of 13 facilities had a functioning premature unit despite calculated gestational age <36 weeks in 45.6% of evaluated neonates. Intravenous fluids and oxygen were available in 9 out of 13 of facilities, while antibiotics and essential basic equipment were available in more than two thirds. Medication dosing errors were common; under-dosage for ampicillin, gentamicin and cloxacillin was found in 44.0%, 37.9% and 50% of cases, respectively, while over-dosage was found in 20.0%, 24.2% and 19.9%, respectively. Physician or assistant physician staffing levels by the WHO indicator levels (WISN) were generally low.

CONCLUSION

Key aspects of neonatal care were found to be poorly documented or incorrectly implemented in this appraisal of neonatal care in Kilimanjaro. Efforts towards quality assurance and enhanced motivation of staff may improve outcomes for this vulnerable group.

Neonatal sepsis at Muhimbili National Hospital, Dar es Salaam, Tanzania; aetiology, antimicrobial sensitivity pattern and clinical outcome

Background

Neonatal sepsis contributes significantly to morbidity and mortality among young infants. The aetiological agents as well as their susceptibility to antimicrobial agents are dynamic. This study determined aetiology, antimicrobial susceptibility and clinical outcome of neonatal sepsis at Muhimbili National Hospital.

Methods

Three hundred and thirty neonates admitted at the Muhimbili National Hospital neonatal ward between October, 2009 and January, 2010 were recruited. Standardized questionnaires were used to obtain demographic and clinical information. Blood and pus samples were cultured on MacConkey, blood and chocolate agars and bacteria were identified based on characteristic morphology, gram stain appearance and standard commercially prepared biochemical tests. Antimicrobial sensitivity testing was performed for ampicillin, cloxacillin, gentamicin, amikacin, cefuroxime and ceftriaxone on Mueller Hinton agar using the Kirby Bauer diffusion method.

Results

Culture proven sepsis was noted in 24% (74/330) of the study participants. Isolated bacterial pathogens were predominantly Staphylococcus aureus, Klebsiella spp and Escherichia coli. Klebsiella spp 32.7% (17/52) was the predominant blood culture isolate in neonates aged below seven days while Staphylococcus aureus 54.5% (12/22) was commonest among those aged above seven days. Staphylococcus aureus was the predominant pus swabs isolate for both neonates aged 0–6 days 42.2% (98/232) and 7–28 days 52.3% (34/65). Resistance of blood culture isolates was high to ampicillin 81.1% (60/74) and cloxacillin 78.4% (58/74), moderate to ceftriaxone 14.9% (11/74) and cefuroxime 18.9% (14/74), and low to amikacin 1.3% (1/74). Isolates from swabs had high resistance to ampicillin 89.9% (267/297) and cloxacillin 85.2 (253/297), moderate resistance to ceftriaxone 38.0% (113/297) and cefuroxime 36.0% (107/297), and low resistance to amikacin 4.7% (14/297). Sepsis was higher in neonates with fever and hypothermia (p=0.02), skin pustules (p<0.001), umbilical pus discharge and abdominal wall hyperemia (p=0.04). Presence of skin pustules was an independent predictor of sepsis OR 0.26, 95% CI (0.10-0.66) p=0.004. The overall death rate was 13.9% (46/330), being higher in neonates with sepsis 24.3% (18/74) than those without 10.9% (28/256), p=0.003.

Conclusions

Staphylococcus aureus was predominant isolate followed by Klebsiella and Escherichia coli. There was high resistance to ampicillin and cloxacillin. Mortality rate due to neonatal sepsis was high in our setting. Routine antimicrobial surveillance should guide the choice of antibiotics for empirical treatment of neonatal sepsis.

Forecasting burden of long-term disability from neonatal conditions: results from the Projahnmo I trial, Sylhet, Bangladesh

INTRODUCTION

The burden of disease resulting from neonatal conditions is substantial in developing countries. From 2003 to 2005, the Projahnmo I programme delivered community-based interventions for maternal and newborn health in Sylhet, Bangladesh. This analysis quantifies burden of disability and incorporates non-fatal outcomes into cost-effectiveness analysis of interventions delivered in the Projahnmo I programme.

METHODS

A decision tree model was created to predict disability resulting from preterm birth, neonatal meningitis and intrapartum-related hypoxia ('birth asphyxia'). Outcomes were defined as the years lost to disability (YLD) component of disability-adjusted life years (DALYs). Calculations were based on data from the Projahnmo I trial, supplemented with values from published literature and expert opinion where data were absent.

RESULTS

195 YLD per 1000 neonates [95% confidence interval (CI): 157-241] were predicted in the main calculation, sensitive to different DALY assumptions, disability weights and alternative model structures. The Projahnmo I home care intervention may have averted 2.0 (1.3-2.8) YLD per 1000 neonates. Compared with calculations based on reductions in mortality alone, the cost-effectiveness ratio decreased by only 0.6% from $105.23 to $104.62 ($65.15-$266.60) when YLD were included, with 0.6% more DALYs averted [total 338/1000 (95% CI: 131-542)].

DISCUSSION

A significant burden of disability results from neonatal conditions in Sylhet, Bangladesh. Adding YLD has very little impact on recommendations based on cost-effectiveness, even at the margin of programme adoption. This model provides guidance for collecting data on disabilities in new settings.

Cause-specific neonatal mortality in a neonatal care unit in Northern Tanzania: a registry based cohort study

Background

The current decline in under-five mortality shows an increase in share of neonatal deaths. In order to address neonatal mortality and possibly identify areas of prevention and intervention, we studied causes of admission and cause-specific neonatal mortality in a neonatal care unit at Kilimanjaro Christian Medical Centre (KCMC) in Tanzania.

Methods

A total of 5033 inborn neonates admitted to a neonatal care unit (NCU) from 2000 to 2010 registered at the KCMC Medical Birth Registry and neonatal registry were studied. Clinical diagnosis, gestational age, birth weight, Apgar score and date at admission and discharge were registered. Cause-specific of neonatal deaths were classified by modified Wigglesworth classification. Statistical analysis was performed in SPSS 18.0.

Results

Leading causes of admission were birth asphyxia (26.8%), prematurity (18.4%), risk of infection (16.9%), neonatal infection (15.4%), and birth weight above 4000 g (10.7%). Overall mortality was 10.7% (536 deaths). Leading single causes of death were birth asphyxia (n = 245, 45.7%), prematurity (n = 188, 35.1%), congenital malformations (n = 49, 9.1%), and infections (n = 46, 8.6%). Babies with birth weight below 2500 g constituted 29% of all admissions and 52.1% of all deaths. Except for congenital malformations, case fatality declined with increasing birth weight. Birth asphyxia was the most frequent cause of death in normal birth weight babies (n = 179/246, 73.1%) and prematurity in low birth weight babies (n = 178/188, 94.7%). The majority of deaths (n = 304, 56.7%) occurred within 24 hours, and 490 (91.4%) within the first week.

Conclusions

Birth asphyxia in normal birth weight babies and prematurity in low birth weight babies each accounted for one third of all deaths in this population. The high number of deaths attributable to birth asphyxia in normal birth weight babies suggests further studies to identify causal mechanisms. Strategies directed towards making obstetric and newborn care timely available with proper antenatal, maternal and newborn care support with regular training on resuscitation skills would improve child survival.

Predictors of positive blood culture and deaths among neonates with suspected neonatal sepsis in a tertiary hospital, Mwanza-Tanzania

BACKGROUND

Neonatal sepsis is a significant cause of morbidity and mortality in neonates. Appropriate clinical diagnosis and empirical treatment in a given setting is crucial as pathogens of bacterial sepsis and antibiotic sensitivity pattern can considerably vary in different settings. This study was conducted at Bugando Medical Centre (BMC), Tanzania to determine the prevalence of neonatal sepsis, predictors of positive blood culture, deaths and antimicrobial susceptibility, thus providing essential information to formulate a policy for management of neonatal sepsis.

METHODS

This was a prospective cross sectional study involving 300 neonates admitted at BMC neonatal unit between March and November 2009. Standard data collection form was used to collect all demographic data and clinical characteristics of neonates. Blood culture was done on Brain Heart Infusion broth followed by identification of isolates using conventional methods and testing for their susceptibility to antimicrobial agents using the disc diffusion method.

RESULTS

Among 770 neonates admitted during the study period; 300 (38.9%) neonates were diagnosed to have neonatal sepsis by WHO criteria. Of 300 neonates with clinical neonatal sepsis 121(40%) and 179(60%) had early and late onset sepsis respectively. Positive blood culture was found in 57 (47.1%) and 92 (51.4%) among neonates with early and late onset neonatal sepsis respectively (p = 0.466). Predictors of positive blood culture in both early and late onset neonatal sepsis were inability to feed, lethargy, cyanosis, meconium stained liquor, premature rupture of the membrane and convulsion. About 49% of gram negatives isolates were resistant to third generation cephalosporins and 28% of Staphylococcus aureus were found to be Methicillin resistant Staphylococcus aureus (MRSA). Deaths occurred in 57 (19%) of neonates. Factors that predicted deaths were positive blood culture (p = 0.0001), gram negative sepsis (p = 0.0001) and infection with ESBL (p = 0.008) or MRSA (p = 0.008) isolates.

CONCLUSION

Our findings suggest that lethargy, convulsion, inability to feed, cyanosis, PROM and meconium stained liquor are significantly associated with positive blood culture in both early and late onset disease. Mortality and morbidity on neonatal sepsis is high at our setting and is significantly contributed by positive blood culture with multi-resistant gram negative bacteria.

Adult and paediatric mortality patterns in a referral hospital in Liberia 1 year after the end of the war

The aim of this study was to describe and analyse hospital mortality patterns after the Liberian war. Data were collected retrospectively from January to July 2005 in a referral hospital in Monrovia, Liberia. The overall fatality rate was 17.2% (438/2543) of medical admissions. One-third of deaths occurred in the first 24h. The adult fatality rate was 23.3% (241/1034). Non-infectious diseases accounted for 56% of the adult deaths. The main causes of death were meningitis (16%), stroke (14%) and heart failure (10%). Associated fatality rates were 48%, 54% and 31% respectively. The paediatric fatality rate was 13.1% (197/1509). Infectious diseases caused 66% of paediatric deaths. In infants <1 month old, the fatality rate was 18% and main causes of death were neonatal sepsis (47%), respiratory distress (24%) and prematurity (18%). The main causes of death in infants > or =1 month old were respiratory infections (27%), malaria (23%) and severe malnutrition (16%). Associated fatality rates were 12%, 10% and 19%. Fatality rates were similar to those found in other sub-Saharan countries without a previous conflict. Early deaths could decrease through recognition and early referral of severe cases from health centres to the hospital and through assessment and priority treatment of these patients at arrival.

Pathogens associated with sepsis in newborns and young infants in developing countries

INTRODUCTION

Knowledge of pathogens causing infections in young infants (up to 90 days of life) is essential for devising community-based management strategies. Most etiological data from developing countries are hospital-based and may have little relevance to communities in which most babies are born at home.

METHODS

We searched the literature for studies from developing countries reporting etiology of community-acquired infections (sepsis, pneumonia, meningitis) published since 1980. Hospital-based studies reporting early onset sepsis, sepsis among babies admitted from, or born at home were included.

RESULTS

Of 63 studies, 13 focused on community-acquired infections, but limited data were available from home-born neonates. In the first week of life (3209 isolates), Klebsiella species (25%), Escherichia coli (15%), and Staphylococcus aureus (18%) were major pathogens. Group B streptococci (GBS) were relatively uncommon (7%), although regional differences existed. After the first week of life (835 isolates), S. aureus (14%), GBS (12%), Streptococcus pneumoniae (12%), and nontyphoidal Salmonella species (13%) were most frequent. S. pneumoniae (27%) was most common in the postneonatal period (among 141 isolates). Gram-negatives predominated (77%) among home-delivered babies (among 170 isolates).

CONCLUSIONS

Limited information is available on etiology of serious bacterial infections in community settings. Hospital-based studies suggest that most infections in the first week of life are due to Gram-negative pathogens, and many may be environmentally rather than maternally-acquired, owing to unhygienic delivery practices. Such practices may also explain the predominance of Gram-negative infections among home-born infants, although data from home settings are limited. These findings have implications for developing prevention and management strategies in communities and hospitals.

Cracking the whip on childhood mortality--role of the specialized neonatal unit in Eritrea

Health care services in developing countries are being challenged by high childhood mortality rates. Although there have been tremendous strides made in reducing infant mortality rates largely due to vaccinations and improved standards of living, a lot remains to be done to reduce neonatal mortality. Achievement of the Millennium Development Goal (MDG) number 4 on childhood mortality will remain unattainable in most developing countries unless purpose based interventions targeted at reducing neonatal mortality are instituted. This viewpoint is based on the experiences gained in Eritrea, a country that gained independence less than twenty years ago following a protracted war that left a trail of destruction of infrastructure in general and health facilities in particular. War that broke out with Ethiopia less than 10 years into its independence and border conflicts followed by a no peace no war stalemate situation aggravated by frequent droughts have continued to throttle economic recovery, reconstruction and rehabilitative efforts. The population is estimated at 3.5 million comprising of nine ethnic groups who speak different languages. The country has a surface area of 124,000 km2 which shares borders with Sudan, Ethiopia, Djibouti and the Red Sea.

CONCLUSION

Attainment of the MDG number 4 on reduction of childhood mortality can be achieved by addressing morbidities of the neonate where the bottle neck currently appears to be sited.

Epidemiology of hospital-acquired bloodstream infections in a Tunisian pediatric intensive care unit: a 2-year prospective study

BACKGROUND

There are few data providing rates of nosocomial bloodstream infections (NBI) in pediatric intensive care patients from developing regions of the world.

OBJECTIVES

To describe the epidemiology of NBI in a Tunisian pediatric intensive care unit (PICU).

METHODS

A prospective surveillance study from January 2004 through December 2005 was performed in the PICU of the Children's Hospital of Tunis. All patients who remained in the PICU for more than 48 hours were included. Centers for Disease Control and Prevention criteria were applied for the diagnosis of NBI.

RESULTS

Six hundred forty-seven patients aged 0 to 15 years were included. Forty-one NBIs occurred in 38 patients. The NBI rate was 7/1000 patient days (6.3/100 admissions). Twenty-seven NBIs (66%) occurred in patients with central venous catheter (CVC). CVC-associated infection rate was 14.8 per 1000 catheter days. Gram-negative rods were involved in 53.6% of NBIs. The most common organisms causing NBIs were Staphylococcus aureus (26.8%), Klebsiella pneumoniae (19.5%) and Coagulase-negative staphylococci (17%). Staphylococcus aureus was methicillin-resistant in 9.1% of cases. Eighty-seven percent of Klebsiella pneumoniae isolates had extended-spectrum beta-lactamases. The PICU crude mortality rate of infected patients was 42% (versus 5.9% in noninfected patients; P< .001). Multivariate logistic regression analyses demonstrated device utilization ratio greater than 1 (odds ratio [OR]=8.46; 95% confidence interval [CI] 3.11-23; P< .001) and previous colonization with multidrug resistant gram-negative rods (OR=2; 95% CI 1.39-2.89; P< .001) significantly related to NBI.

CONCLUSIONS

Considering the high incidence of NBI resulted from multiple drug-resistant gram-negative rods in our center, implementation of improved infection control practices is required.

[Epidemiology of nosocomial bacterial infections in a neonatal and pediatric Tunisian intensive care unit]

OBJECTIVE

The authors had for aim to describe the epidemiology of nosocomial bacterial infections in the neonatal and pediatric intensive care unit of the Tunis children's hospital.

DESIGN

A prospective surveillance study was made from January 2004 to December 2004. All patients remaining in the intensive care unit for more than 48 h were included. CDC criteria were applied for the diagnosis of nosocomial infections.

RESULTS

340 patients including 249 (73%) neonates were included. 22 patients presented with 22 nosocomial bacterial infections. The incidence and the density incidence rates of nosocomial bacterial infections were 6.5% and 7.8 per 1,000 patient-days, respectively. Two types of infection were found: bloodstream infections (68.2%) and pneumonias (22.7%). Bloodstream infections had an incidence and a density incidence rate of 4.4% and 15.3 per 1,000 catheter-days, respectively. Pneumonia had an incidence and a density incidence rate of 2% and 4.4 per 1,000 mechanical ventilation-days, respectively. The most frequently isolated pathogens were Gram-negative bacteria (68%) with Klebsiella pneumoniae isolates accounting for 22.7%. The most common isolate in bloodstream infections was K. Pneumoniae (26.7%), which was multiple drug-resistant in 85% of the cases, followed by Staphylococcus aureus (20%). Pseudomonas aeruginosa was the most common isolate in pneumonia (28.6%). Associated factors of nosocomial infection were invasive devices and colonization with multiple drug-resistant Gram-negative bacteria.

CONCLUSIONS

The major type of nosocomial bacterial infections in our unit was bloodstream infection and the majority of infections resulted from Gram-negative bacteria. Factors associated with nosocomial bacterial infections were identified in our unit.

Hospital-acquired neonatal infections in developing countries

Hospital-born babies in developing countries are at increased risk of neonatal infections because of poor intrapartum and postnatal infection-control practices. We reviewed data from developing countries on rates of neonatal infections among hospital-born babies, range of pathogens, antimicrobial resistance, and infection-control interventions. Reported rates of neonatal infections were 3-20 times higher than those reported for hospital-born babies in industrialised countries. Klebsiella pneumoniae, other gram-negative rods (Escherichia coli, Pseudomonas spp, Acinetobacter spp), and Staphylococcus aureus were the major pathogens among 11,471 bloodstream isolates reported. These infections can often present soon after birth. About 70% would not be covered by an empiric regimen of ampicillin and gentamicin, and many might be untreatable in resource-constrained environments. The associated morbidity, mortality, costs, and adverse effect on future health-seeking behaviour by communities pose barriers to improvement of neonatal outcomes in developing countries. Low-cost, "bundled" interventions using systems quality improvement approaches for improved infection control are possible, but should be supported by evidence in developing country settings.
