Does the antimicrobial-impregnated peripherally inserted central catheter decrease the CLABSI rate in neonates? Results from a retrospective cohort study.

Background: The use of antimicrobial-impregnated peripherally inserted central catheters (PICCs) has been introduced in the last few years to neonatal units aiming to reduce central line-associated bloodstream infection (CLABSI). Methods: This retrospective observational study aimed to compare the CLABSI rates and other catheter-related parameters including the insertion success rates and catheter-related complications in the antimicrobial-impregnated and conventional (ordinary) PICCs in NICU between 2017 and 2020. Results: Our dedicated PICC team including physicians and nurses inserted 1,242 conventional (PremiCath and NutriLine) and 791 antimicrobial-impregnated PICCs (PremiStar) over the study period from 2017 to 2020. Of those 1,242 conventional PICCs, 1,171 (94.3%) were 1 Fr single lumen and only 71 (5.7%) were 2 Fr double lumen. The mean ± SD [median (IQR)] for the birth weight in all babies who had a PICC line was 1,343.3 ± 686.75 [1,200 (900, 1,500)] g, while the mean ± SD for the gestational age was 29.6 ± 4.03 [29 (27, 31)] weeks. The mean ± SD [median (IQR)] age at the time of insertion for all catheters was 9.3 ± 21.47 [2 (1, 9)] days, while the mean ± SD [median (IQR)] dwell time was 15.7 ± 14.03 [12 (8, 17)] days. The overall success rate of the PICC insertion is 1,815/2,033 (89.3%), while the first attempt success rate is 1,290/2,033 (63.5%). The mean ± SD [median (IQR)] gestational age, birth weight, age at catheter insertion, and catheter dwell time were 28.8 ± 3.24 [29, (26, 31)] weeks, 1,192.1 ± 410.3 [1,150, (900, 1,450)] g, 6.3 ± 10.85 [2, (1, 8)] days, and 17.73 ± 17.532 [13, (9, 18)] days in the antimicrobial-impregnated catheter compared with 30.1 ± 4.39 [29, (27, 32)] weeks (P < 0.001), 1,439.5 ± 800.8 [1,240, (920, 1,520)] g (P < 0.001), 11.1 ± 25.9 [1, (1, 9)] days (P < 0.001), and 14.30 ± 10.964 [12, (8, 17)] days (P < 0.001), respectively, in the conventional PICCs. The use of the antimicrobial-impregnated catheter was not associated with any significant reduction in the CLABSI rate (per 1,000 days dwell time), either the overall [P = 0.11, risk ratio (RR) (95% CI): 0.60 (0.32, 1.13)] or the yearly CLABSI rates. Conclusions: The use of miconazole and rifampicin-impregnated PICCs did not reduce the CLABSI rate in neonates compared with conventional PICCs. However, it has a higher overall rate of elective removal after completion of therapy and less extravasation/infiltration, occlusion, and phlebitis compared with the conventional PICCs. Further large RCTs are recommended to enrich the current paucity of evidence and to reduce the risk of bias. Neonatal PICCs impregnation by other antimicrobials is a recommendation for vascular access device manufacturers.

Neonatal Simulation Program: A 5 Years Educational Journey From Qatar.

We describe the process of implementation, adaptation, expansion and some related clinical intuitional impacts of the neonatal simulation program since its launch in 2016 in a non-simulation neonatal unit. The team has developed 6 types of curricula: 1 full-day course and 5 half-day workshops. A total of 35 free of charge simulation courses/workshops were conducted, 32 in Qatar and 3 abroad with a total of 799 diverse participants. There was a steady increase in the overall success rate of PICC insertion from 81.7% (309/378) to 97.6% (439/450) across 3 years (P < 0.0001). The first attempt PICC insertion success rate has been also increased from 57.7% (218/378) to 66.9% (301/450) across 3 years. The mean duration of PICC insertion has been improved from 39.7 ± 25 to 34.9 ± 12.4 min after implementing the program (P = 0.33). The mean duration of the LISA catheter insertion at the beginning of the workshop was 23.5 ± 15.9 compared to 12.1 ± 8.5 s at the end of the workshop (P = 0.001). When it came to clinical practise in real patients by the same participants, the overall LISA catheter insertion success rate was 100% and the first attempt success rate was 80.4%. The mean duration of LISA catheter insertion in real patients was 26.9 ± 13.9 s compared to the end of the workshop (P = 0.001). The mean duration of the endotracheal intubation at the beginning of the workshop was 12.5 ± 9.2 compared to 4.2 ± 3.8 s at the end of the workshop (P = 0.001). In real patients, the first-attempt intubation success rate has been improved from 37/139 (26.6%) in the first year to 141/187 (75.5%) in the second year after the program implementation (P = 0.001). The mean duration of successful endotracheal intubation attempts has been improved from 39.1 ± 52.4 to 20.1 ± 9.9 s (P = 0.78). As per the participants, the skills learned in the program sessions help in protecting neonates from potential harm and improve the overall neonatal outcome. Implementing a neonatal simulation program is a promising and feasible idea. Our experience can be generalised and replicated in other neonatal care institutions.

Peripherally inserted central catheters versus non-tunnelled ultrasound-guided central venous catheters in newborns: a retrospective observational study.

OBJECTIVES: We aimed to compare the success rates and other catheter-related parameters between peripherally inserted central catheters (PICCs) and non-tunnelled ultrasound-guided central venous catheters (USG-CVCs) including femoral, jugular, brachiocephalic and subclavian lines. DESIGN: This was a retrospective observational study. SETTING: The study was performed in a level III neonatal intensive care unit (NICU) in Qatar, as a single-site study. PARTICIPANTS: This study included 1333 neonates who required CVC insertion in the NICU from January 2016 to December 2018. Of those, we had 1264 PICCs and 69 non-tunnelled USG-CVCs. OUTCOME MEASURES: The success rate and other catheter-related complications in the two groups. RESULTS: The overall success rate was 88.4% in the USG-CVCs (61/69) compared with 90% in the PICCs (1137/1264) group (p=0.68). However, the first prick success rate was 69.4% in USG-CVCs (43/69) compared with 63.6% in the PICCs (796/1264) group. Leaking and central line-associated blood stream infection (CLABSI) were significantly higher in the USG-CVC group compared with the PICC group (leaking 16.4% vs 2.3%, p=0.0001) (CLABSI 8.2% vs 3.1%, p=0.03). CLABSI rates in the PICC group were 1.75 per 1000 catheter days in 2016 and 3.3 in 2017 compared with 6.91 in 2016 (p=0.0001) and 14.32 in 2017 (p=0.0001) for the USG-CVCs. USG-CVCs had to be removed due to catheter-related complications in 52.5% of the cases compared with 29.9% in PICCs, p=0.001. In 2018, we did not have any non-tunnelled USG-CVCs insertions in our NICU. CONCLUSIONS: The overall complication rate, CLABSI and leaking are significantly higher in non-tunnelled USG-CVCs compared with the PICCs. However, randomised controlled trials with larger sample sizes are desired. Proper central venous device selection and timing, early PICC insertion and early removal approach, dedicated vascular access team development, proper central venous line maintenance, central line simulation workshops and US-guided insertions are crucial elements for patient safety in NICU.

Maternal and neonatal outcomes in mothers with diabetes mellitus in qatari population.

BACKGROUND: Diabetes Mellitus (DM) is a major cause of maternal, fetal, and neonatal morbidities. Our objective was to estimate the effect of both pre-pregnancy and gestational DM on the growth parameters of newborns in the Qatari population. METHODS: In this population-based cohort study, we compared the data of neonates born to Qatari women with both pre-pregnancy and gestational diabetes mellitus in 2017 with neonates of healthy non-diabetic Qatari women. RESULTS: Out of a total of 17020 live births in 2017, 5195 newborns were born to Qatari women. Of these, 1260 were born to women with GDM, 152 were born to women with pre-pregnancy DM and 3783 neonates were born to healthy non-diabetic (control) women. The prevalence of GDM in the Qatari population in 2017 was 24.25%. HbA1C% before delivery was significantly higher in women with pre-pregnancy DM (mean 6.19 ± 1.15) compared to those with GDM (mean 5.28 ± 0.43) (P <0.0001). The mean birth weight in grams was 3066.01 ± 603.42 in the control group compared to 3156.73 ± 577.88 in infants born to women with GDM and 3048.78 ± 677.98 in infants born to women with pre-pregnancy DM (P <0.0001). There was no statistically significant difference regarding the mean length (P= 0.080), head circumference (P= 0.514), and rate of major congenital malformations (P= 0.211). Macrosomia (Birth weight > 4000 gm) was observed in 2.7% of the control group compared to 4.8% in infants born to women with GDM, and 4.6% in infants born to women with pre-pregnancy DM (P= 0.001). Multivariate logistic regression analysis demonstrated that higher maternal age (adjusted OR 2.21, 95% CI 1.93, 2.52, P<0.0001), obesity before pregnancy (adjusted OR 1.71, 95% CI 1.30, 2.23, P<0.0001), type of delivery C-section (adjusted OR 1.25, 95% CI 1.09, 1.44, P=0.002), and body weight to gestational age LGA (adjusted OR 2.30, 95% CI 1.64, 2.34, P<0.0001) were significantly associated with increased risk of GDM. CONCLUSION: Despite the multi-disciplinary antenatal diabetic care management, there is still an increased birth weight and an increased prevalence of macrosomia among the infants of diabetic mothers. More efforts should be addressed to improve the known modifiable factors such as women's adherence to the diabetic control program. Furthermore, pre-pregnancy BMI was found to be significantly associated with gestational DM, and this is a factor that can be addressed during pre-conceptional counseling.

Reintubation rates after extubation to different non-invasive ventilation modes in preterm infants.

INTRODUCTION: Respiratory Distress Syndrome (RDS) is a common cause of neonatal morbidity and mortality in premature newborns. In this study, we aim to compare the reintubation rate in preterm babies with RDS who were extubated to Nasal Continuous Positive Airway Pressure (NCPAP) versus those extubated to Nasal Intermittent Positive Pressure Ventilation (NIPPV). METHODS: This is a retrospective study conducted in the Neonatal Intensive Care Unit (NICU) of Women's Wellness and Research Center (WWRC), Doha, Qatar. The medical files (n = 220) of ventilated preterm infants with gestational age ranging between 28 weeks 0 days and 36 weeks + 6 days gestation and extubated to non-invasive respiratory support (whether NCPAP, NIPPV, or Nasal Cannula) during the period from January 2016 to December 2017 were reviewed. RESULTS: From the study group of 220 babies, n = 97 (44%) babies were extubated to CPAP, n = 77 (35%) were extubated to NIPPV, and n = 46 (21%) babies were extubated to Nasal Cannula (NC). Out of the n = 220 babies, 18 (8.2%) were reintubated within 1 week after extubation. 14 of the 18 (77.8%) were reintubated within 48 h of extubation. Eleven babies needed reintubation after being extubated to NCPAP (11.2%) and seven were reintubated after extubation to NIPPV (9.2%), none of those who were extubated to NC required reintubation (P = 0.203). The reintubation rate was not affected by extubation to any form of non-invasive ventilation (P = 0.625). The mode of ventilation before extubation does not affect the reintubation rate (P = 0.877). The presence of PDA and NEC was strongly associated with reintubation which increased by two and four-folds respectively in those morbidities. There is an increased risk of reintubation with babies suffering from NEC and BPD and this was associated with an increased risk of hospital stay with a P-value ranging (from 0.02-0.003). Using multivariate logistic regression, NEC the NEC (OR = 5.52, 95% CI 1.26, 24.11, P = 0.023) and the vaginal delivery (OR = 0.23, 95% CI 0.07, 0.78, P = 0.018) remained significantly associated with reintubation. CONCLUSION: Reintubation rates were less with NIPPV when compared with NCPAP, however, this difference was not statistically significant. This study highlights the need for further research studies with a larger number of neonates in different gestational ages birth weight categories. Ascertaining this information will provide valuable data for the factors that contribute to re-intubation rates and influence the decision-making and management of RDS patients in the future.

Effect of implementing an Epicutaneo-Caval Catheter team in Neonatal Intensive Care Unit.

BACKGROUND: Until the 1980s, central vascular access in the Neonatal Intensive Care Unit was predominantly delivered by umbilical catheters and only and if needed by surgical cutdowns or subclavian vein catheterization through blind percutaneous venipuncture. In the early 1980s, epicutaneo-caval catheters were successfully introduced. METHODS: In our Neonatal Intensive Care Unit, a dedicated team to insert epicutaneo-caval catheters was formally established in January 2017, including 12 neonatologists and 1 neonatal nurse practitioner. A before- versus after-intervention study was designed to determine whether the establishment of the epicutaneo-caval catheter insertion team is associated with increased success rates and a decreased risk of catheter-related complications. Success rates and other catheter-related parameters were traced from 2016 onward. Collected data were analyzed for three consecutive years: 2016, 2017, and 2018. RESULTS: The epicutaneo-caval catheter team inserted 1336 catheters over 3 years. Both first prick (from 57.7% to 66.9%; p = 0.023) and overall success (from 81.7% to 97.6%; p < 0.0001) rates significantly improved. In 2018, the number of tunneled or surgically inserted central venous catheters came down to zero (p < 0.0001). Overall catheter-related complications were significantly lower following the epicutaneo-caval catheter team's establishment (p < 0.0001) while there was no significant decrease noted (p = 0.978) in central line-associated bacterial stream infection rates. CONCLUSION: A dedicated epicutaneo-caval catheter team is a promising intervention to increase success rates and significantly decrease catheter-related complications in Neonatal Intensive Care Unit. Standardizing epicutaneo-caval catheter placement is important; however, standardizing catheter maintenance seems essential to the improvement of central line-associated bacterial stream infection rates.

Effect of Maternal Preeclampsia on Hematological Profile of Newborns in Qatar.

Background: Preeclampsia is a major cause of pregnancy-related maternal, fetal, and neonatal morbidities and mortalities. We aimed to review the effect of maternal preeclampsia on the hematological profile of newborns in the Qatari population. Methods: In this case-control study, we reviewed data and complete blood count results of neonates born to Qatari women diagnosed of preeclampsia in 2017 in comparison with data of a control group. Statistical analysis was done using unpaired t-test, chi-square test, and logistic regression analysis. Results: A total of 108 neonates of women with preeclampsia and 103 neonates of healthy normotensive women were recruited. The mean weight, length, head circumference, placental weight, and gestational age were significantly lower (P < 0.05) in neonates born to women with preeclampsia. Only 13% of babies born to women with preeclampsia developed neonatal thrombocytopenia which is significantly higher compared to only 2% in the control group (chi-square χ 2 = 9.14; P < 0.05) in neonates born to women with preeclampsia. No significant difference (P > 0.05) was noted between the two groups regarding the white blood cells (WBC) or the absolute neutrophilic count (ANC). Multivariate logistic regression showed that the gestational age, birth weight, length, and ANC had significant association with preeclampsia (P < 0.05). Conclusions: We found that there was a positive association between preeclampsia and neonatal thrombocytopenia in the Qatari population. Prematurity, placenta insufficiency, fetal growth restriction, and need for neonatal resuscitation were significantly higher in babies born to women with preeclampsia. We recommend that hematological parameters of neonates of those women should be properly monitored to reduce the chances of developing complications.
