Glucose-6-phosphate dehydrogenase deficiency and neonatal indirect hyperbilirubinemia: a retrospective cohort study among 40,305 consecutively born babies.

BACKGROUND AND OBJECTIVE: Glucose-6-phosphate dehydrogenase deficiency (G6PDD) being highly prevalent in the Middle East, the primary objective was to estimate the incidence of neonatal jaundice among G6PD-deficient neonates and to explore its association with various risk factors. METHODS: This retrospective cohort study includes 7 years data of neonates diagnosed with G6PDD between 1st January 2015, and 30 September 2022, from Al Wakra Hospital, HMC Qatar. RESULTS: Among the 40,305 total births, 1013 had G6PDD with an incidence of 2.51%. Of all the G6PDD babies, 24.6% (249/1013) received phototherapy and three babies required exchange transfusion. Statistically significant associations were noted between the need for phototherapy and gestational age, gestational age groups, birth weight, and birth weight groups, but logistic regression analysis showed significant association for phototherapy only with the gestational age group. CONCLUSION: Universal screening and proper follow-up is essential for G6PDD as it plays crucial role in neonatal jaundice.

Kaiser Permanente early-onset sepsis calculator as a safe tool for reducing antibiotic use among chorioamnionitis-exposed term neonates: Qatar experience.

Being an important cause of early-onset neonatal sepsis, clinical chorioamnionitis in the mother results in frequent laboratory workup and antibiotic use for the neonate. Neonatal intensive care units (NICUs) in Qatar follow the categorical approach recommended by the Centers for Disease Control and Prevention, USA, and all chorioamnionitis-exposed neonates receive antibiotics.Our project aimed to reduce antibiotic use among chorioamnionitis-exposed, asymptomatic term babies by adopting the early-onset sepsis calculator (EOSCAL). Reduction of blood culture and NICU stay duration were added as secondary objectives later.The Institute of Healthcare Improvement Model of Improvement was used. Antibiotic use rate was the primary outcome measure. Blood culture rate and early transfer to the postnatal ward were added after 1 year. The process measures included the EOSCAL use rate and calculation error rate. The rate of positive culture among untreated babies within the first week was taken as a balancing measure. Monthly data were collected from February 2020 and entered as run charts. Calculation errors were dealt by multiple PDSAs. Additional outcome measures were added in January 2021. Data collection and monitoring continued till December 2022.Among 3837 inborn NICU admissions, 464 (12 %) were chorioamnionitis-exposed babies. Of them, 341 (74%) cases were eligible for inclusion. Among eligible cases, 270 (79%) did not receive antibiotics. Blood culture could be avoided among 106 (97% of low-risk babies) and NICU stay was reduced among 45 (92% of eligible low-risk babies). None of the untreated babies developed sepsis during the first week.Implementation of this project effectively and safely reduced the antibiotic use and blood culture rate among term, well-appearing babies exposed to chorioamnionitis. The project resulted in enhanced patient safety, experience and flow and reduced cost. It is recommendable to other NICU settings in Qatar.

Suspected clinical chorioamnionitis with peak intrapartum temperature <380C: the prevalence of confirmed chorioamnionitis and short term neonatal outcome.

BACKGROUND: Chorioamnionitis (CA) affects up to 3.9% of all deliveries worldwide and is one of the leading causes of early-onset neonatal sepsis. Fever≥380C is an essential criterion for the diagnosis of clinical CA. Obstetricians frequently take the maternal risk factors into consideration, and many mothers are treated as CA even with peak intrapartum temperature (PIT) between 37.60C to 37.90C if they have other clinical signs and risk factors. AIM: To estimate the prevalence of confirmed chorioamnionitis and adverse neonatal outcomes among those mothers with PIT below 380C. MATERIALS AND METHODS: Retrospective chart review among mothers delivered at Al-Wakra Hospital, Qatar, between1stJanuary2016 to 31stDecember 2019 with a clinical suspicion of CA. RESULTS: Among 21,471 mothers, 442 were suspected of having CA (2.06%, 95% CI 1.88 to 2.26%). After exclusions, 415 were included in the study, 203(48.9%) mothers had PIT between 37.6-37.90C. There was no significant difference in the rate of confirmed CA between the low (<380C) and higher (≥380C) temperature groups (25.4%Vs.31.3%, OR0.75, 95%CI0.46-1.25 , p.262). More patients in the low-temperature group received paracetamol for PIT between 37.6 to 37.9 0C, while it was less frequently used for such milder elevation in higher temperature group (88.2%Vs.38.9%, OR11.69, 95% CI 6.46-2.15, p <.001). CONCLUSION: The incidence of suspected clinical CA in our institution was within the international rates. Although nearly half of the mothers with suspected clinical CA had peak temperature below the recommended diagnostic criteria, the rate of confirmed CA and neonatal outcome was not significantly different from those with PIT≥380C. Early antipyretic use might have affected further elevation of temperature.

Effects of Labor Epidural Analgesia on Short Term Neonatal Morbidity.

BACKGROUND: Epidural Analgesia (EA) is the most effective and most commonly used method for pain relief during labor. Some researchers have observed an association between EA and increased neonatal morbidity. But this observation was not consistent in many other studies. OBJECTIVES: The primary objective of the study was to examine whether exposure to epidural analgesia increased the risk of NICU admission. The secondary objectives included the risks of clinical chorioamnionitis, instrumental delivery, neonatal depression, respiratory distress, birth trauma, and neonatal seizure during the first 24 hours of life. METHODS: This was a retrospective cohort study involving 2360 low-risk nulliparous women who delivered at AWH, Qatar, during the two years between January 2016 December and 2017. Short-term neonatal outcomes of the mothers who received EA in active labor were compared with a similar population who did not receive EA. As secondary objectives, labor parameters like maternal temperature elevation, duration of the second stage of labor, and instrumental delivery were compared. RESULTS: Significantly higher numbers of neonates were admitted to the NICU from the EA group (P<0.001, OR 1.89, 95% CI 1.45 to 2.46). They were more likely to have respiratory distress (P=0.01, OR 1.49, 95% CI 1.07 to 2.07), birth injuries (P=0.02, OR =1.71, 95% CI 1.06 to 2.74), admission temperature>37.5 °C (P=0.04, OR 3.40, 95% CI 1.00 to 11.49), need for oxygen on the first day (P=0.04, OR 1.44, 95% CI 1.01 to 2.07) and receive antibiotics (P<0.001, OR 2.06,95% CI 1.47 to 2.79). There was no difference in the Apgar score at 1 minute (P=0.12), need of resuscitation at birth (P=0.05), neonatal white cell count (P=0.34), platelet count (P=0.38) and C reactive protein (P=0.84). Mothers who received EA had a lengthier second stage (P<0.001), temperature elevation >37.5°C (P<0.001, OR 7.40, 95% CI 3.93 to 13.69) and instrumental delivery (P<0.001, OR 2.13, 95% CI 1.69 to 2.68). CONCLUSION: EA increases NICU admission, antibiotic exposure, neonatal birth injuries, need for positive pressure ventilation at birth, and respiratory distress in the first 24 hours of life. Mothers on epidural analgesia have prolonged second stage of labor, a higher rate of instrumental delivery, meconium-stained amniotic fluid, fetal distress, and temperature elevation.

The Effect of High-Dose Postpartum Maternal Vitamin D Supplementation Alone Compared with Maternal Plus Infant Vitamin D Supplementation in Breastfeeding Infants in a High-Risk Population. A Randomized Controlled Trial.

In view of continuing reports of high prevalence of severe vitamin D deficiency and low rate of infant vitamin D supplementation, an alternative strategy for prevention of vitamin D deficiency in infants warrants further study. The aim of this randomized controlled trial among 95 exclusively breastfeeding mother-infant pairs with high prevalence of vitamin D deficiency was to compare the effect of six-month post-partum vitamin D3 maternal supplementation of 6000 IU/day alone with maternal supplementation of 600 IU/day plus infant supplementation of 400 IU/day on the vitamin D status of breastfeeding infants in Doha, Qatar. Serum calcium, parathyroid hormone, maternal urine calcium/creatinine ratio and breast milk vitamin D content were measured. At baseline, the mean serum 25-hydroxyvitamin D (25(OH)D) of mothers on 6000 IU and 600 IU (35.1 vs. 35.7 nmol/L) and in their infants (31.9 vs. 29.6) respectively were low but similar. At the end of the six month supplementation, mothers on 6000 IU achieved higher serum 25(OH)D mean ± SD of 98 ± 35 nmol/L than 52 ± 20 nmol/L in mothers on 600 IU (p < 0.0001). Of mothers on 6000 IU, 96% achieved adequate serum 25(OH)D (≥50 nmol/L) compared with 52%in mothers on 600 IU (p < 0.0001). Infants of mothers on 600 IU and also supplemented with 400 IU vitamin D3 had slightly higher serum 25(OH)D than infants of mothers on 6000 IU alone (109 vs. 92 nmol/L, p = 0.03); however, similar percentage of infants in both groups achieved adequate serum 25(OH)D ≥50 nmol/L (91% vs. 89%, p = 0.75). Mothers on 6000 IU vitamin D3/day also had higher human milk vitamin D content. Safety measurements, including serum calcium and urine calcium/creatinine ratios in the mother and serum calcium levels in the infants were similar in both groups. Maternal 6000 IU/day vitamin D3 supplementation alone safely optimizes maternal vitamin D status, improves milk vitamin D to maintain adequate infant serum 25(OH)D. It thus provides an alternative option to prevent the burden of vitamin D deficiency in exclusively breastfeeding infants in high-risk populations and warrants further study of the effective dose.

Antenatal Bartter syndrome presenting with vomiting and constipation mimicking subacute intestinal obstruction in a 20-day-old neonate.

Antenatal Bartter syndrome is a rare condition that can present with different clinical features. These features include early onset maternal polyhydramnios, failure to thrive, prematurity and nephrocalcinosis.We are presenting this 20-day-old girl who had an antenatal history of polyhydramnios. She developed persistent non-bilious vomiting that was associated with constipation soon after birth. She presented with failure to thrive and features suggestive of intestinal obstruction. On the initial evaluation, she was noted to have hypokalaemic, hyponatraemic metabolic alkalosis. The initial work-up was done to exclude surgical and renal causes of her presentation, and the diagnosis was confirmed by gene analysis to be type III-classic Bartter syndrome. She was closely monitored for her growth and development with the appropriate salt replacement therapy.

Pediatric case of acute right-sided abdominal pain: diagnosis is not always appendicitis.

Omental infarction (OI) is a rare cause of acute abdominal pain occurring in 0.1% of children, which is typically diagnosed during surgery for suspected appendicitis. We present the case of a 7-year-old Pakistani girl. She presented with acute, severe, progressive, right-sided abdominal pain, which was present for 12 hours before presentation. No constitutional symptoms such as fever, anorexia, nausea or vomiting were present. Clinical examination revealed an adequately growing child following the 50th centile. She had severe generalized abdominal tenderness with rebound tenderness and guarding, mainly on the right lower abdominal quadrant, with all other system examinations normal. She had mildly increased inflammatory markers, and her initial abdominal ultrasound scan result was within normal limits. She had laparoscopic surgery following a diagnosis of suspected acute appendicitis; however, an intraoperative diagnosis of OI was made. This was later confirmed by histopathology. This case report highlights the importance of including OI in the differential diagnosis list of acute abdominal pain in children, in addition to the importance of computed tomography (CT) as the gold standard tool to aid diagnosis. In the presence of typical symptoms and signs of OI, a CT scan can assist and guide the management of similar cases. This course of action is suggested for the reason that OI typically runs a self-limited course and conservative care may be the most appropriate recommended course of action. Consequently, unnecessary operations could be avoided due to the diagnosis confirmation of studying images.

Prevalence and risk factors for low vitamin D status among breastfeeding mother-infant dyads in an environment with abundant sunshine.

PURPOSE: Evaluation of vitamin D (vD) status and risk factors for low vD among breastfeeding mother-infant dyads in a population at high risk for vD deficiency. SUBJECTS AND METHODS: We measured serum 25-hydroxyvitamin D (25(OH)D) and parathyroid hormone at 1 month postpartum in 60 consecutive exclusively breastfeeding Arab mother-infant dyads enrolled in a high dose vD supplementation study to prevent vD deficiency in Doha, Qatar, (latitude 25°N) during summer months. Data were collected on demography, sun exposure, and vD supplementation. Comparison with a US cohort was evaluated. vD deficiency was defined as serum 25(OH)D <50 nmol/L and severe deficiency categorized as 25(OH)D <25 nmol/L in mothers and infants. RESULTS: Mean maternal age was 29 years and 77% had college or university education. Maternal median 25(OH)D was 32.5 nmol/L and 78% were vD-deficient and 20% had 25(OH)D <25 nmol/L. Only 42% of mothers had reportedly taken vD supplements postpartum and median dietary vD intake (119 IU/day) and calcium (490 mg/day) were low. Maternal median sun index score (sun exposure [hours/week] × body surface area exposed while outdoors) was 0. Maternal 25(OH)D correlated with percent body surface area exposure while outdoors (rs=0.37, P=0.004). Infant median 25(OH)D was 20 nmol/L and 83% were deficient, while 58% had 25(OH)D <25 nmol/L. Infant 25(OH)D correlated with maternal levels (rs=0.41, P=0.001). None of the infants received vD supplement at 1 month of age and median sun index score was 0. Infant's parathyroid hormone showed negative correlations with 25(OH)D (rs=-0.28, P=0.03). Sun exposure, vD supplementation rate, and vD status were lower in Doha than Cincinnati, US cohort. CONCLUSION: vD deficiency is common in breastfeeding mother-infant dyads in this sunny environment and is associated with sun avoidance and low vD intake. We suggest corrective vD supplement of breastfeeding mothers and their infants, which should preferably start during pregnancy.

Poisoning emergency visits among children: a 3-year retrospective study in Qatar.

BACKGROUND: Poisoning in toddlers and infants is almost always unintentional due to their exploratory behavior, which is different from adults. The prevalence and background of childhood poisoning in Qatar is still unknown. The aim of this study is to explore the extent of childhood poisoning in Qatar and, specifically, to describe the frequency of poisoning as a cause of Accident & Emergency (A&E) admission, the demographic profile of affected patients, the circumstances leading to exposure, and the specific agents involved in poisoning among children under age 14 in our setting. METHODS: This study was a cross-sectional survey of children up to 14 years old utilizing retrospective data between October 2009 and October 2012. The data were collected from the childhood poisoning case registry and patient medical records at the Accident and Emergency (A&E) Unit of all the Hamad Medical Corporation hospitals. Pharmacists reviewed all the handwritten medical records. Data written on the data collection form were transferred into excel and later into SPSS version 21. The data were analyzed using frequencies and percentages, and a chi-square test was used for categorical variables. RESULTS: Out of 1179 registered poisoning cases listed in the registry, only 794 cases (67.3%) were usable and included in the final analysis. A&E admissions for unintentional poisoning for children accounted for 0.22% of all A&E admissions from 2009 to 12. The majority of poisoning cases happened among children between 1 and 5 years old (n = 704, 59.7%). Cases were more frequent among non-Qatari than Qatari children (39.4% vs. 28.5%). Most cases occurred in the living room (28.2%) and typically took place in the afternoon (29.2%). Analgesic and antipyretic medicines were the most common agents ingested by children (n = 194, 36.9%), specifically paracetamol (n = 140, 26.6%). CONCLUSIONS: Cases of unintentional poisoning are higher among children aged 1 to 5 years, males and non-Qatari. Most cases occurred in the living room and typically took place in the afternoon. The most common type of poison ingested by children was medicines, i.e., analgesics and antipyretics, specifically paracetamol.

Socio-demographic and consanguinity risk factors associated with low birthweight.

OBJECTIVE: To examine socio-demographic and biological risk factors associated with mothers giving birth to a low birthweight newborn among Arab women in Qatar. METHODS: The case-control study was conducted at two main tertiary hospitals in Qatar in which participants were prospectively identified from January 2010 to April 2011. Data were collected by survey on maternal ethnicity, age, education, socioeconomic status, body mass index, consanguinity and gestational age. A total of 16,500 newborns were screened for low birthweight. A total of 863 mothers of low birthweight cases and an equal number of mothers of normal-weight babies were studied. RESULTS: Qatari mothers were found to be 1.2 times as likely to have a low birthweight (< 2500g) newborn compared to other Arab women (p < 0.057). Mothers with a primary school education were 1.6 times as likely as university educated mothers to have a low birthweight newborn (p < 0.006). Likewise, obese mothers were 1.5 times as likely as their normal-weight counterparts (p < 0.009). Consanguineous couples who were first-degree cousins were 1.9 times as likely as non-related couples to have a low birthweight newborn (p < 0.001). Newborns with a gestational age of < 37 weeks were 19.6 times as likely as those > or = 37 weeks to have a low birthweight (p < 0.001). CONCLUSION: The majority of the risk factors associated with low birthweight were modifiable. Health education campaigns need to target the most vulnerable groups to reduce the rates of low birthweight among Arabs in Qatar.

The national perinatal mortality rate in the State of Qatar during 2011; trends since 1990 and comparative analysis with selected high-income countries: the PEARL study project.

OBJECTIVE: To prospectively ascertain Qatar's national perinatal mortality rate (PMR) during 2011, compare it with recent data from selected high-income countries, and analyze trends in Qatar's PMR between 1990 and 2011 using historical data. STUDY DESIGN: A national prospective cohort study. METHODS: National data on live births, stillbirths, and early neonatal mortality (day 0­6) were collected from all public and private maternity units in Qatar (1st January­December 31st 2011) and compared with historical perinatal mortality data (1990­2010) ascertained from the database of maternity and neonatal units of Women's Hospital and annual reports of Hamad Medical Corporation (HMC). For inter-country comparison, country data were extracted from the World Health Statistics published by WHO in 2011 and from the European Perinatal Health Report published by the Europeristat project in 2008. RESULTS: A total of 20,725 births (20,583 live births plus 142 stillbirths) were recorded during the study period. Qatar's national PMR during 2011 was 9.55 [early neonatal mortality rate (ENMR) 2.7 and stillbirth rate (SBR) 6.85], which was a significant improvement from a PMR of 13.2 in 1990 [risk ratio (RR) 0.72, 95% confidence interval 0.58­0.89, P=0.002]. This improvement in PMR was more significant in ENMR (P<0.001) than in SBR (P=0.019). The stillbirths constituted 55% of PMR in 1990, which increased to 71.72% of PMR during 2011. The RR of PMR had a significant downwards trend between 1990 and 2011 (P=0.016). Qatar's 2011 PMR, SBR, and ENMR are comparable to those of selected high-income counties. CONCLUSIONS: Qatar's PMR, ENMR, and SBR have significantly improved between 1990 and 2011, and are currently comparable to those of selected high-income countries. An in-depth research to assess the correlates and determinants of stillbirth and perinatal mortality in Qatar is indicated.

Pattern of Maternal Complications and Low Birth Weight: Associated Risk Factors among Highly Endogamous Women.

Objective. The objective of the study was to examine the pattern of low birth weight LBW, maternal complications, and its related factors among Arab women in Qatar. Design. This is a prospective hospital-based study. Setting. The study was carried out in Women's Hospital, Doha. Subjects and Methods. Pregnant women in their third trimester were identified in the log book of Women's Hospital and recruited into the study during first week of January 2010 to July 2011. Only 1674 (out of 2238) Arab women (74.7%) consented to participate in this study. Data on clinical and biochemistry parameters were retrieved from medical records. Follow-up data on neonatal outcome was obtained from labor room register. Results. The incidence of LBW (<2500 g) was 6.7% among Arab women during 2010 in Qatar. Distribution of gestational diabetes mellitus (GDM), antepartum hemorrhage (APH), maternal anemia, premature rupture of membrane (PROM), maternal occupation, parity, sheesha smoking, and parental consanguinity were significantly different (P < 0.05) between mothers of LBW and normal birth weight NBW (≥2500 g) babies. Multivariable logistic regression analysis revealed that previous LBW, consanguinity, parity, smoking shesha, GDM, APH, anemia, PROM, maternal occupation, and housing condition were significantly associated with LBW adjusting for gestational age. Conclusion. Maternal complications such as GDM, APH, anemia, PROM, and smoking shesha during pregnancy are significantly increasing the risk of LBW outcome. Screening and prompt treatment for maternal complications and health education for smoking cessation during routine antenatal visits will help in substantial reduction of LBW outcome.

The impact of the interpregnancy interval on birth weight and other pregnancy outcomes / O impacto do intervalo entre gestações no peso de recém-nascidos e outros desfechos da gravidez

To investigate the relationship between the interpregnancy interval and low birth weight and other pregnancy outcomes. METHODS: this case-control study was carried out in hospitals from January 2010 to April 2011. For cases, mothers of 1216 newborns with birth weight<2500 g were approached and 854 mothers participated (70.2 percent). For controls, mothers of 1158 newborns with >2500 g were approached and 854 mothers participated in this study (73.7 percent). Face-to-face interviews were conducted to complete the questionnaires. RESULTS: of the newborn babies with low birth weight, the risk was higher among mothers with a short interpregnancy interval (40.3 percent), whereas for infants with normal birth weight, the majority of the mothers had a longer interpregnancy interval of 24 months (44.7 percent). A short interpregnancy interval of 612 months was more common among women of <25years (49.4 percent; p<0.001) and those who were illiterate (13.1 percent; p=0.043) with a higher risk of low birth weight compared to the controls. Prenatal care during the 1st trimester was lower in women with low birth weight children (p<0.001). Normal delivery was observed less in women with a short birth interval among cases (58.7 percent) compared to controls (79 percent) (p=0.001). A J-shaped association was observed between low birth weight and the interpregnancy interval. CONCLUSIONS: a short interpregnancy interval is associated with an increased risk of low birth weight, especially in younger and illiterate women...

Investigar a relação entre o intervalo entre gestações e o baixo peso de recém-nascidos e outras conseqüências da gestação. MÉTODOS: este estudo caso-controle foi realizado em hospitais entre janeiro de 2010 e abril de 2011. Dentre as mães dos 1216 recém-nascidos com peso <2500 g, 854 (70,2 por cento) aceitaram participar do estudo de caso. No grupo controle, dentre as mães dos 1158 recém-nascidos com peso > 2500 g, participaram 854(73,7 por cento). Para completar os questionários, foram conduzidas entrevistas face a face. RESULTADOS: dos recém-nascidos com baixo peso, o fator de risco foi mais alto entre as mães com curto intervalo intergestacional (40,3 por cento), enquanto para recém-nascidos com peso normal a maioria das mães tinham uma boa margem de intervalo intergestacional de 24 meses (44,7 por cento). Curtos intervalo intergestacional (6 a 12 meses) foi mais comum entre mulheres de <25 anos (49,4 por cento; p<0,001) e analfabetas (13,1 por cento; p=0,043), com mais alto risco de baixo peso quando comparado aos controle. Cuidados pre-natais durante o primeiro trimestre foi menor nas mulheres com crianças de baixo peso (p<0,001). Menos partos normais foi observado em mulheres com curtos intervalos de nascimento para os casos (58,7 por cento) comparados aos controles (79 por cento) (p=0,001). Uma associação não monotônica tipo função J, foi observada entre o baixo peso e intervalo intergestacional. CONCLUSÕES: um curto intervalo entre gestações é associado a um risco maior de nascerem bebês de baixo peso, principalmente entre mulheres mais jovens e analfabetas...

Improvements in Birth Weight-specific Neonatal Mortality Rates in the State of Qatar between 2003 & 2010 and a Comparative Analysis with the Vermont Oxford Network Database Report of 2007: A PEARL Study Review.

OBJECTIVE: The study aimed to develop a national reference on birth weight-specific neonatal survival in the State of Qatar to facilitate parental counseling. STUDY DESIGN: This was a retrospective, analytic, and comparative study. MATERIALS AND METHODS: The birth weight-specific neonatal mortality data for the years 2003 and 2010, collected from the admission and discharge registers of the neonatal intensive care unit, were stratified using the stratifications given in Vermont Oxford Network (VON) 2007 annual report. Category-wise birth weight-specific mortality and relative risk (RR) of death were compared between Qatar data (2003 and 2010) and VON 2007 report. RESULTS: Qatar's neonatal mortality rate (NMR) dropped from 5 of 1000 in 2003 to 4.4 of 1000 in 2010 (P=0.443) which was significant for birth weight categories 501-750 g and 751-1000 g (P=0.026 and P=0.05, respectively). Qatar's NMR in 2010 was significantly lower than VON's NMR during 2007 (P<0.001) though VON's NMR was significantly lower among birth weight categories 751-1000 g and 1001-1500 g (P=0.001 and P=0.003, respectively). The RR of mortality decreased with increasing birth weight. The decline was very sharp for birth weight categories between 500 and 1500g. The RR was 25 times higher in babies with birth weight less than 750 g as compared to babies with birth weight ≥ 2550 g, both in Qatar and VON data. For birth weight categories 751-1000 g and 1001-1500 g, the RR was twice in Qatar as compared to the VON report (16.8 versus 7.8, and 5.5 versus 2.7, respectively). CONCLUSIONS: Qatar's current overall and birth weight-specific NMRs are comparable with the VON report except in birth weight categories 751-1000 g and 1001-1500 g which were higher in Qatar. This needs further in-depth qualitative analysis.

A PEARL Study Analysis of National Neonatal, Early Neonatal, Late Neonatal, and Corrected Neonatal Mortality Rates in the State of Qatar during 2011: A Comparison with World Health Statistics 2011 and Qatar's Historic Data over a Period of 36 Years (1975-2011).

OBJECTIVE: To prospectively ascertain Qatar's national Neonatal Mortality Rate (NMR), Early Neonatal Mortality Rate (ENMR), and Late Neonatal Mortality Rate (LNMR) during 2011, compare it with recent data from high-income countries, and analyze trends in Qatar's NMR's between 1975 and 2011 using historic data. STUDY DESIGN: A National prospective cohort-study. MATERIALS AND METHODS: National data on live births and neonatal mortality was collected from all public and private maternity facilities in Qatar (1(st) January-December 31(st) 2011) and compared with historical neonatal mortality data (1975-2010) ascertained from the database of maternity and neonatal units of Women's Hospital and annual reports of Hamad Medical Corporation. For inter country comparison, country data of 2009 was extracted from World Health Statistics 2011 (WHO) and the European Perinatal Health report (2008). RESULTS: A total of 20583 live births were recorded during the study period. Qatar's national NMR during 2011 was 4.95, ENMR 2.7, LNMR 2.2, and cNMR 3.33. Between 1975 and 2011, Qatar's population increased by 10-fold, number of deliveries by 7.2 folds while relative risk of NMR decreased by 87% (RR 0.13, 95% CI 0.10-0.18, P<0.001), ENMR by 91% (RR 0.09, 95% CI 0.06-0.12, P<0.001) and LNMR by 58% (RR 0.42, 95% CI 0.23-0.74, P=0.002). The comparable ranges of neonatal mortality rates from selected high-income West European countries are: NMR: 2-5.7, ENMR 1.5-3.8, and LNMR 0.5-1.9. CONCLUSIONS: The neonatal survival in the State of Qatar has significantly improved between 1975 and 2011. The improvement has been more marked in ENMR than LNMR. Qatar's current neonatal mortality rates are comparable to most high-income West European countries. An in-depth research to assess the correlates and determinants of neonatal mortality in Qatar is indicated.

Gestational age specific neonatal survival in the State of Qatar (2003-2008) - a comparative study with international benchmarks.

OBJECTIVE: To analyze and compare the current gestational age specific neonatal survival rates between Qatar and international benchmarks. STUDY DESIGN: An analytical comparative study. PLACE AND DURATION OF STUDY: Women's Hospital, Hamad Medical Corporation, Doha, Qatar, from 2003-2008. METHODOLOGY: Six year's (2003-2008) gestational age specific neonatal mortality data was stratified for each completed week of gestation at birth from 24 weeks till term. The data from World Health Statistics by WHO (2010), Vermont Oxford Network (VON, 2007) and National Statistics United Kingdom (2006) were used as international benchmarks for comparative analysis. RESULTS: A total of 82,002 babies were born during the study period. Qatar's neonatal mortality rate (NMR) dropped from 6/1000 in 2003 to 4.3/1000 in 2008 (p < 0.05). The overall and gestational age specific neonatal mortality rates of Qatar were comparable with international benchmarks. The survival of < 27 weeks and term babies was better in Qatar (p=0.01 and p < 0.001 respectively) as compared to VON. The survival of > 32 weeks babies was better in UK (p=0.01) as compared to Qatar. The relative risk (RR) of death decreased with increasing gestational age (p < 0.0001). Preterm babies (45%) followed by lethal chromosomal and congenital anomalies (26.5%) were the two leading causes of neonatal deaths in Qatar. CONCLUSION: The current total and gestational age specific neonatal survival rates in the State of Qatar are comparable with international benchmarks. In Qatar, persistently high rates of low birth weight and lethal chromosomal and congenital anomalies significantly contribute towards neonatal mortality.

Socioeconomic associations of improved maternal, neonatal, and perinatal survival in Qatar.

This retrospective study analyzed the temporal association between socioeconomic development indices and improved maternal, neonatal, and perinatal survival in the State of Qatar over a period of 35 years (1974-2008). We explored the association between reduction in poverty, improvement in maternal education, and perinatal health care on the one hand, and increased maternal, neonatal, and perinatal survival on the other hand. Yearly mortality data was ascertained from the perinatal and neonatal mortality registers of the Women's Hospital and the national database in the Department of Preventive Medicine at Hamad Medical Corporation in Doha. A total of 323,014 births were recorded during the study period. During these 35 years, there was a remarkable decline (P < 0.001) in Qatar's neonatal mortality rate from 26.27/1000 in 1974 to 4.4/1000 in 2008 and in the perinatal mortality rate from 44.4/1000 in 1974 to 10.58/1000 in 2008. Qatar's maternal mortality rate remained zero during 1993, 1995, and then in 1998-2000. The maternal mortality rate was 11.6/100,000 in 2008. For the rest of the years it has been approximately 10/100,000. Across the study period, the reduction in poverty, increase in maternal education, and improved perinatal health care were temporally associated with a significant improvement in maternal, neonatal, and perinatal survival. The total annual births increased five-fold during the study period, with no negative impact on survival rates. Neonatal mortality rates in Qatar have reached a plateau since 2005. We also conducted a substudy to assess the association between improvements in survival rates in relation to health care investment. For this purpose, we divided the study period into two eras, ie, era A (1974-1993) during which major health care investment was in community-based, low-cost interventions, and era B (1994-2008) during which the major health care investment was in high-technology institutional interventions. Although from 1974-1993 (era A) the per capita health expenditure increased by only 19% as compared with a 137% increase in 1994-2008 (era B). The decline in neonatal and perinatal mortality rates was three times steeper during era A than in era B. The decline in neonatal and perinatal mortality rates was also significant (P < 0.001) when analyzed separately for era A and era B. We concluded that across the 35-year period covered by our study, the reduction in poverty, increased maternal education, and improved perinatal health care were temporally associated with improved maternal, neonatal, and perinatal survival in the State of Qatar. From the subanalysis of era A and era B, we concluded that low-cost, community-based interventions, on the background of socioeconomic development, have a stronger impact on maternal, neonatal, and perinatal survival as compared with high-cost institutional interventions.
