Quality of health care around the time of childbirth during the COVID-19 pandemic: Results from the IMAgiNE EURO study in Norway and trends over time

OBJECTIVE

To describe maternal perception of the quality of maternal and newborn care (QMNC) in facilities in Norway during the first year of COVID-19 pandemic.

METHODS

Women who gave birth in a Norwegian facility from March 1, 2020, to October 28, 2021, filled out a structured online questionnaire based on 40 WHO standards-based quality measures. Quantile regression analysis was performed to assess changes in QMNC index over time.

RESULTS

Among 3326 women included, 3085 experienced labor. Of those, 1799 (58.3%) reported that their partner could not be present as much as needed, 918 (29.8%) noted inadequate staff numbers, 183 (43.6%) lacked a consent request for instrumental vaginal birth (IVB), 1067 (34.6%) reported inadequate communication from staff, 78 (18.6%) reported fundal pressure during IVB, 670 (21.7%) reported that they were not treated with dignity, and 249 (8.1%) reported experiencing abuse. The QMNC index increased gradually over time (3.68 points per month, 95% CI, 2.83-4.53 for the median), with the domains of COVID-19 reorganizational changes and experience of care displaying the greatest increases, while provision of care was stable over time.

CONCLUSION

Although several measures showed high QMNC in Norway during the first year of the COVID-19 pandemic, and a gradual improvement over time, several findings suggest that gaps in QMNC exist. These gaps should be addressed and monitored.

Rates of instrumental vaginal birth and cesarean and quality of maternal and newborn health care in private versus public facilities: Results of the IMAgiNE EURO study in 16 countries

OBJECTIVE

To explore the quality of maternal and newborn care (QMNC) during the COVID-19 pandemic by facility type among 16 European countries, comparing rates of instrumental vaginal birth and cesarean.

METHODS

Women who gave birth in the WHO European Region from March 1, 2020, to February 7, 2022, answered a validated online questionnaire. Rates of instrumental birth, instrumental vaginal birth, and cesarean, and a QMNC index were calculated for births in public versus private facilities.

RESULTS

Responses from 25 206 participants were analyzed. Women giving birth in private compared with public facilities reported significantly more frequent total cesarean (32.5% vs 19.0%; aOR 1.70; 95% CI 1.52-1.90), elective cesarean (17.3% vs 7.8%; aOR 1.90; 95% CI 1.65-2.19), and emergency cesarean before labor (7.4% vs 3.9%; aOR 1.39; 95% CI 1.14-1.70) (P < 0.001 for all comparisons), with analyses by country confirming these results. QMNC index results were heterogeneous across countries and regions in the same country and were largely affected by geographical distribution of regions rather than by type of facility alone.

CONCLUSION

The study confirms that births in private facilities have higher odds of cesarean. It also suggests that QMNC should be closely monitored in all facilities to achieve high-quality care, independent of facility type or geographical distribution.

Quality of maternal and newborn care in Switzerland during the COVID-19 pandemic: A cross-sectional study based on WHO quality standards

OBJECTIVE

To explore quality of maternal and newborn care (QMNC) in healthcare facilities during the COVID-19 pandemic in Switzerland.

METHODS

Women giving birth in Switzerland answered a validated online questionnaire including 40 WHO standards-based quality measures. QMNC score was calculated according to linguistic region and mode of birth. Differences were assessed using logistic regression analysis adjusting for relevant variables.

RESULTS

A total of 1175 women were included in the analysis. Limitations in QMNC during the pandemic were reported by 328 (27.9%) women. Several quality measures, such as deficient communication (18.0%, n = 212), insufficient number of healthcare professionals (19.7%, n = 231), no information on the newborn after cesarean (26.5%, n = 91) or maternal and newborn danger signs (34.1%, n = 401 and 41.4% n = 487, respectively) suggested preventable gaps in QMNC. Quality measures significantly differed by linguistic region and mode of birth. Multivariate analysis established a significantly lower QMNC for women in French- and Italian-speaking regions compared with the German-speaking region. Moreover, in several quality indicators reflecting communication with healthcare providers, women who did not answer the questionnaire in one of the Swiss national languages had significantly worse scores than others. A significant lower QMNC was also found for young and primiparous women and for those who experienced cesarean or instrumental vaginal birth.

CONCLUSION

Women giving birth in Switzerland during the pandemic reported notable gaps in QMNC. Providers should be attuned to women who are younger, primiparous, and those who had an emergency cesarean or instrumental vaginal birth given the lower QMNC reported by these groups. Women who did not respond in a Swiss national language may need improved communication strategies.

Quality of Informed Consent Practices around the Time of Childbirth: A Cross-Sectional Study in Italy

Background: Few studies have explored consent request practices during childbirth. Objective: We explored consent request practices during childbirth in a referral hospital and research centre in Italy, capturing both women and health workers’ perspectives. Methods: Data were collected using self-administrated questionnaires between December 2016 and September 2018. Nine key maternal and newborn procedures were analysed. Associations between consent requests and women characteristics were explored by multiple logistic regression. Results: Among 1244 women, the rate of consent requests varied widely, with caesarean section (CS) showing the highest rate (89.1%) and neonatal conjunctivitis prophylaxis presenting the lowest rate (11.4%). Information provided on “risks/benefits” and “reasons” for procedures by health staff was most often not comprehensive for procedures of interest (range 18.6–87.4%). The lack of informed consent is not specifically linked to any pattern of women characteristics. According to 105 health workers, adequate protocols and standard forms for consent requests were available in 67.6% and 78.1% of cases, respectively, while less than one third (31.4%) reported having received adequate training and supportive supervision on how to deliver informed consent. Conclusions: Study findings align with previous evidence showing that consent request practices during childbirth need to be largely improved. More research is needed to investigate effective strategies for improvement.

Comparison of National Growth Standards for Turkish Infants and Children with World Health Organization Growth Standards

OBJECTIVE

Using World Health Organization (WHO) standards in pediatric practice is still controversial in many countries. It is suggested that national growth charts best reflect the genetic and ethnic characteristics of a population. The aim of this study was to compare length/height, body weight, and body mass index (BMI) in healthy Turkish children of ages 0 to 18 with those proposed by WHO as the international growth standards.

METHODS

The data of Turkish children were collected from infant/child population aged 0-5 years (2391 boys, 2102 girls) and children of ages between 6-18 years (1100 boys, 1020 girls). For comparison, the 50^th, 3^rd, and 97^th percentile curves for length/height, weight, and BMI in Turkish children were plotted together with respective WHO data.

RESULTS

Heights were essentially similar in the Turkish and WHO data at ages between 3-10 years. Turkish children were markedly taller compared to the WHO standards after the age of 10 years. Evaluation of the 3rd percentile data revealed that Turkish boys were shorter than the WHO subjects in the first 2 years of life. From 6 months of age, Turkish children showed higher weight for age values in the 3^rd, 50^th, and 97^th percentiles. In all age groups between 6 months and 3 years, and in between 6-18 years of age, Z-score values, as well as the 50^th, 15^th, 85^th, and 95^th percentile values were higher in Turkish children. The differences were particularly noteworthy at ages 1-2 years and in the pubertal years.

CONCLUSION

WHO growth standards do not reflect the growth of Turkish children and may substantially alter the prevalence of short stature and underweight in Turkish children in the 0-5 years age group. When assessing the nutritional and growth status of children, national growth standards may be more appropriate.

Development of mRNA Vaccines: Scientific and Regulatory Issues

The global research and development of mRNA vaccines have been prodigious over the past decade, and the work in this field has been stimulated by the urgent need for rapid development of vaccines in response to an emergent disease such as the current COVID-19 pandemic. Nevertheless, there remain gaps in our understanding of the mechanism of action of mRNA vaccines, as well as their long-term performance in areas such as safety and efficacy. This paper reviews the technologies and processes used for developing mRNA prophylactic vaccines, the current status of vaccine development, and discusses the immune responses induced by mRNA vaccines. It also discusses important issues with regard to the evaluation of mRNA vaccines from regulatory perspectives. Setting global norms and standards for biologicals including vaccines to assure their quality, safety and efficacy has been a WHO mandate and a core function for more than 70 years. New initiatives are ongoing at WHO to arrive at a broad consensus to formulate international guidance on the manufacture and quality control, as well as nonclinical and clinical evaluation of mRNA vaccines, which is deemed necessary to facilitate international convergence of manufacturing and regulatory practices and provide support to National Regulatory Authorities in WHO member states.

Comparison of Postnatal Growth Charts of Singleton Preterm and Term Infants Using World Health Organization Standards at 40-160 Weeks Postmenstrual Age: A Chinese Single-Center Retrospective Cohort Study

There remains controversy regarding whether the growth charts constructed from data of term infants, such as those produced by the World Health Organization (WHO) standards, can appropriately evaluate the postnatal growth of preterm infants. This retrospective cohort study, conducted in the First Affiliated Hospital of Shandong First Medical University in Jinan China, aimed to compare the postnatal growth charts of singleton preterm and term infants using WHO standards at 40-160 weeks postmenstrual age (PMA). A total of 5,459 and 15,185 sets of longitudinal measurements [length/height, weight, head circumference (HC), and body mass index (BMI)] from birth to 160 weeks PMA were used to construct growth charts for 559 singleton preterm (mean PMA at birth, 33.84 weeks) and 1,596 singleton term infants (born at 40 weeks PMA), respectively, using the Generalized Additive Models for Location, Scale, and Shape (GAMLSS) method. Z-scores (prematurity corrected) were calculated using WHO Anthro software. Compared to WHO standards, all parameters of preterm infants were increased, especially in terms of length/height and weight; the gap between the two almost spanned two adjacent centile curves. Compared to term controls, the length/height, weight, and BMI of preterm infants were higher at 40 weeks PMA, surpassed by term infants at 52-64 weeks PMA, and quite consistent thereafter. The HC of preterm infants at 40-160 weeks PMA was quite consistent with both term controls and the WHO standards. The Z-scores for length/height, weight, and BMI of preterm infants relative to the WHO standards gradually decreased from 1.20, 1.13, and 0.74 at 40-44 weeks PMA to 0.67, 0.42, and 0.03 at 132-160 weeks PMA, respectively; Z-scores for HC of preterm infants rapidly decreased from 0.73 to 0.29 at 40-50 weeks PMA, and then fluctuated in the range of 0.08-0.23 at 50-160 weeks PMA. Preterm infants had higher growth trajectories than the WHO standards and similar but not identical trajectories to term infants during the first 2 years of life. These findings reemphasize the necessity of constructing local growth charts for Chinese singleton preterm infants.

Comparison of methodological quality between the 2007 and 2019 Canadian dietary guidelines

OBJECTIVE

With significant shifts in the dietary recommendations between the 2007 and 2019 Canadian dietary guidelines, such as promoting plant-based food intake, reducing highly processed food intake and advocating the practice of food skills, we compared their differences in guideline development methods.

DESIGN

Two reviewers used twenty-five guided criteria to appraise the methods used to develop the most recent dietary guidelines against those outlined in the 2014 WHO Handbook for Guideline Development.

SETTING

Canada.

PARTICIPANTS

2007 and 2019 dietary guidelines.

RESULTS

We found that the 2019 guidelines were more evidence-based and met 80 % (20/25) of the WHO criteria. For example, systematic reviews and health organisation authoritative reports, but not industry reports, constituted the evidence base for the dietary recommendations. However, recommendations on food sustainability and food skill practice were driven primarily by stakeholders' interests. By contrast, less information was recorded about the process used to develop the 2007 guidelines, resulting in 24 % (6/25) consistency with the WHO standards.

CONCLUSIONS

Our analysis suggests that a more transparent and evidence-based approach is used to develop the 2019 Canadian dietary guidelines and that method criteria should support further incorporation of nutrition priorities (food sustainability and food skills) in future dietary guideline development.

Data set on performance evaluation of discharged wastewater quality from Guna water treatment plant for potable water purpose

This article provides to evaluate the quality of discharged water from Guna spring water treatment plant and to compare with WHO drinking water standards and Ethiopian bottled drinking water specification to reuse for potable water purpose. The discharged waste water quality analysis was conducted by Physical, Chemical, Biological and Bacteriological parameters of water in association with set of standards. Atomic adsorption spectroscopy (AAS), Flame photometer, UV–Visible spectrometer and Photo meter were used for characterization discharged water. All water quality parameter was determined in all unit process (softener, sand filter, activated carbon and ultra-filter). Bacteriological analysis (total coli form, fecal coli form and Escherichia coli type1) were conducted. During discharge water quality analysis, the effect of flow rate (2 m³/h, 4 m³/h and 6 m³/h) and discharge time (5,10 and 15 min) have been performed. We provided data set about Atomic adsorption spectroscopy (AAS), Flame photometer, Turbidity meter, Photometer and Bacteriological analysis parameter were verified.

Comparison of Growth Curve Estimates of Infants in São Tomé Island, Africa, with the WHO Growth Standards: A Birth Cohort Study

This birth cohort study compared the infant growth curve estimates in São Tomé Island to the WHO growth standards. Despite this island belonging to a lower-middle-income country, there were several factors favorable for growth that were present. Four-hundred and seventy-five full-term singleton appropriate for-gestational-age infants were enrolled and followed-up to 24 months of age. Weight-for-age, length-for-age, weight-for-length, body mass index-for-age, head circumference-for-age, weight velocity, and length velocity curves were estimated and compared to the WHO standards. In the first 6 months of age, the weight gain was adequate in the presence of a high prevalence of exclusive breastfeeding. Thereafter, weight trajectories tracked close to the WHO standards, except for a progressive decline in the infants growing in higher percentiles, especially in girls. Median length at birth was below the median WHO standards, followed by an early postnatal velocity spurt, which probably reflected the transition from an unfavorable to a more favorable postnatal environment. Thereafter, linear growth faltering was observed without relevant deterioration up to 24 months of age, which was probably due to the presence of protective factors. These results may be useful to implement strategies to further approximate infant growth in São Tomé Island to the WHO standards.

Prevalence and factors associated with stunting and thinness among adolescent students in Northern Ethiopia: a comparison to World Health Organization standards

Background

Adolescence is last chance for curbing the consequences of malnutrition and breaking the intergenerational cycle of malnutrition and poor health. This study aimed to assess the prevalence and the factors associated with stunting and thinness among in-school adolescents in northern Ethiopia using the 2006 World Health Organization (WHO) standards.

Methods

In-school adolescents (n = 348, 10–19 years old) were randomly selected to participate in this cross-sectional study. Anthropometric measurements were carried out to determine the proportion of adolescents who were stunted (height-for-age < −2 Standard Deviation (SD)) and thin (body-mass-index-for-age < −2 SD). T-test was employed to evaluate mean weight and height differences between groups. Pearson chi-square, chi-square trend and Fisher’s exact tests were used to explore the crude association of categorical outcome variables and associated factors. Crude and adjusted associations between the outcome variables (stunting and thinness) and independent variables (socio-demographic, eating behavior and sanitation) were also determined using logistic regression. Stata version 11.1 was used to analyze the data.

Results

The height of the adolescents was 147.6 ± 11.2 cm (mean ± SD) and weight was37.2 ± 9.5 kg. The mean Z-scores of height-for-age and body-mass-index (BMI)-for-age of adolescents were −1.49 and −1.29, respectively. The prevalence of stunting and thinness among adolescents was 28.5 % (boys = 37.7 %; girls = 21.2 %; P = 0.001) and 26.1 % (boys = 32.4; girls = 21.6 %; p = 0.017), respectively. Adolescents in 13–15 year old age group (Adjusted Odds ratio (AOR) = 2.23; 95 % CI: 1.22, 4.08), boys (AOR = 2.53; 95 % CI: 1.52, 4.21) and rural residents (AOR = 2.15; 95 % CI: 1.20, 3.86) had significantly higher odds of being stunted compared to their counterparts. Furthermore, boys had higher (AOR = 1.97; 95 % CI: 1.19, 3.25) odds of being thin compared to girls. Compared to those 10 to 12 years of age, adolescents in 16 to 19 years of age were 53 % (AOR = 0.47; 95 % CI: 0.23, 0.95) less likely to be thin.

Conclusions

Undernutrition is widely prevalent among adolescents in northern Ethiopia. Sex, age and area of residence significantly associated with adolescent undernutrition. The study underlines the need for nutrition interventions targeting rural and boy adolescents.

Standardization of NAT for Blood-Borne Pathogens

Assays based on nucleic acid amplification technology (NAT) are increasingly used for screening of blood and for diagnosis or monitoring of patients. Both regulatory requirements for blood screening and international recommendations for the treatment of patients are based on common reference materials available globally for the standardization of NAT assays. World Health Organization International Standards (WHO ISs) and International Reference Panels (WHO IRPs) are primary reference materials. The characterization and manufacture of WHO reference materials as well as their evaluation is performed on behalf of the WHO by collaborating centers; their establishment is decided upon by the WHO Expert Committee on Biological Standardization (ECBS). The potency of the first WHO IS is defined by the 'international unit' (IU) which should be maintained upon replacement of the IS. The IU, unlike copy number or genome equivalent, is defined by the IS with a physical existence, is available worldwide, and allows traceability and comparability of results. The anticipated use of WHO ISs is the calibration of secondary standards or the validation of essential assay features, e.g. limit of detection.

Multicenter comparison of laboratory performance in cytomegalovirus and Epstein-Barr virus viral load testing using international standards

BACKGROUND

Infections with cytomegalovirus (CMV) and Epstein-Barr virus (EBV) remain important in solid organ transplantation. Quantitative viral nucleic acid testing is a major advance to patient management. These assays are limited by a lack of standardization, resulting in viral load measurements that differ among clinical laboratories. The variability in viral load measurements makes interpretation of multicenter clinical trials data difficult. This study compares the current practices in CMV and EBV viral load testing at four large transplant centers participating in multicenter Clinical Trials in Organ Transplantation and the Clinical Trials in Organ Transplantation in Children (CTOT and CTOTC).

METHODS

Viral load testing was performed on well-defined viral preparations according to standard operating procedures at each site.

RESULTS

Among centers, CMV viral load testing was accurate compared to WHO International Standards and within acceptable variation for this testing method. Epstein-Barr virus viral load data were more variable and less accurate despite the use of international standards.

CONCLUSIONS

These data suggest that comparison of CMV, but not EBV, viral load measurements at these sites is possible using current assays and control standards. Standardization of these assays is facilitated using the WHO International Standards and will allow comparison of viral load results among transplant centers. Assay standardization must be performed prior to initiation of multicenter trials.
