Comparison of adverse pregnancy and birth outcomes using archival medical records before and during the first wave of the COVID-19 pandemic in Kinshasa, Democratic Republic of Congo: a facility-based, retrospective cohort study.

BACKGROUND: Little research has been conducted on the impact of the coronavirus disease 2019 (COVID-19) pandemic on either birth outcomes or the ability of archival medical records to accurately capture these outcomes. Our study objective is thus to compare the prevalence of preterm birth, stillbirth, low birth weight (LBW), small for gestational age (SGA), congenital microcephaly, and neonatal bloodstream infection (NBSI) before and during the first wave of the COVID-19 pandemic in Kinshasa, Democratic Republic of Congo (DRC). METHODS: We conducted a facility-based retrospective cohort study in which identified cases of birth outcomes were tabulated at initial screening and subcategorized according to level of diagnostic certainty using Global Alignment of Immunization Safety Assessment in pregnancy (GAIA) definitions. Documentation of any birth complications, delivery type, and maternal vaccination history were also evaluated. The prevalence of each birth outcome was compared in the pre-COVID-19 (i.e., July 2019 to February 2020) and intra-COVID-19 (i.e., March to August 2020) periods via two-sample z-test for equality of proportions. RESULTS: In total, 14,300 birth records were abstracted. Adverse birth outcomes were identified among 22.0% and 14.3% of pregnancies in the pre-COVID-19 and intra-COVID-19 periods, respectively. For stillbirth, LBW, SGA, microcephaly, and NBSI, prevalence estimates were similar across study periods. However, the prevalence of preterm birth in the intra-COVID-19 period was significantly lower than that reported during the pre-COVID-19 period (8.6% vs. 11.5%, p < 0.0001). Furthermore, the level of diagnostic certainty declined slightly across all outcomes investigated from the pre-COVID-19 to the intra-COVID-19 period. Nonetheless, diagnostic certainty was especially low for certain outcomes (i.e., stillbirth and NBSI) regardless of period; still, other outcomes, such as preterm birth and LBW, had moderate to high levels of diagnostic certainty. Results were mostly consistent when the analysis was focused on the facilities designated for COVID-19 care. CONCLUSION: This study succeeded in providing prevalence estimates for key adverse birth outcomes using GAIA criteria during the COVID-19 pandemic in Kinshasa, DRC. Furthermore, our study adds crucial real-world data to the literature surrounding the impact of the COVID-19 pandemic on maternal and neonatal services and outcomes in Africa.

Awareness of obstetric danger signs among pregnant women in the Democratic Republic of Congo: evidence from a nationwide cross-sectional study.

BACKGROUND: Poor awareness of obstetric danger signs is a major contributing factor to delays in seeking obstetric care and hence to high maternal mortality and morbidity worldwide. We conducted the current study to assess the level of agreement on receipt of counseling on obstetric danger signs between direct observations of antenatal care (ANC) consultation and women's recall in the exit interview. We also identified factors associated with pregnant women's awareness of obstetric danger signs during pregnancy in the Democratic Republic of Congo (DRC) METHODS: We used data from the 2017-2018 DRC Service Provision Assessment survey. Agreement between the observation and woman's recall was measured using Cohen's kappa statistic and percent agreement. Multivariable Zero-Inflated Poisson (ZIP) regression was used to identify factors associated with the number of danger signs during pregnancy the woman knew. RESULTS: On average, women were aware of 1.5 ± 1.34 danger signs in pregnancy (range: 0 to 8). Agreement between observation and woman's recall was 70.7%, with a positive agreement of 16.9% at the country level but ranging from 2.1% in Bandundu to 39.7% in Sud Kivu. Using multivariable ZIP analysis, the number of obstetric danger signs the women mentioned was significantly higher in multigravida women (Adj.IRR = 1.38; 95% CI: 1.23-1.55), in women attending a private facility (Adj.IRR = 1.15; 95% CI: 1.01-1.31), in women attending a subsequent ANC visit (Adj.IRR = 1.11; 95% CI: 1.01-1.21), and in women counseled on danger signs during the ANC visit (Adj.IRR = 1.19; 95% CI: 1.05-1.35). There was a regional variation in the awareness of danger signs, with the least mentioned signs in the middle and the most in the eastern provinces. CONCLUSIONS: Our findings indicated poor agreement between directly observed counseling and women's reports that counseling on obstetric danger signs occurred during the current ANC visit. We found that province of residence, provision of counseling on obstetric danger signs, facility ownership, gravidity and the number of ANC visits were predictors of the awareness of obstetric danger signs among pregnant women. These factors should be considered when developing strategies aim at improving women's awareness about obstetric danger signs in the DRC.

Health facility readiness and provider knowledge as correlates of adequate diagnosis and management of pre-eclampsia in Kinshasa, Democratic Republic of Congo.

BACKGROUND: Hypertensive disorders in pregnancy are the second most common cause of maternal mortality in the Democratic Republic of Congo (DRC), accounting for 23% of maternal deaths. This study aimed to assess facility readiness, and providers' knowledge to prevent, diagnose, and treat pre-eclampsia. METHODS: A facility-based cross-sectional study was conducted in 30 primary health centres (PHCs) and 28 referral facilities (hospitals) randomly selected in Kinshasa, DRC. In each facility, all midwives and physicians involved in maternal care provision (n = 197) were included. Data on facility infrastructure and providers' knowledge about pre-eclampsia were collected using facility checklists and a knowledge questionnaire. Facility readiness score was defined as the sum of 13 health commodities needed to manage pre-eclampsia. A knowledge score was defined as the sum of 24 items about the diagnosis, management, and prevention of pre-eclampsia. The score ranges from 0 to 24, with higher values reflecting a better knowledge. The Mann-Witney U test was used to compare median readiness scores by facility type and ownership; and median knowledge scores between midwives in hospitals and in PHCs, and between physicians in hospitals and in PHCs. RESULTS: Overall, health facilities had 7 of the 13 commodities, yielding a median readiness score of 53.8%(IQR: 46.2 to 69.2%). Although all provider groups had significant knowledge gaps about pre-eclampsia, providers in hospitals demonstrated slightly more knowledge than those in PHCs. Midwives in public facilities scored higher than those in private facilities (median(IQR): 8(5 to 12) vs 7(4 to 8), p = 0.03). Of the 197 providers, 91.4% correctly diagnosed severe pre-eclampsia. However, 43.9 and 82.2% would administer magnesium sulfate and anti-hypertensive drugs to manage severe pre-eclampsia, respectively. Merely 14.2 and 7.1% of providers were aware of prophylactic use of aspirin and calcium to prevent pre-eclampsia, respectively. CONCLUSION: Our study showed poor availability of supplies to diagnose, prevent and treat pre-eclampsia in Kinshasa. While providers demonstrated good knowledge regarding the diagnosis of pre-eclampsia, they have poor knowledge regarding its prevention and management. The study highlights the need for strengthening knowledge of providers toward the prevention and management of pre-eclampsia, and enhancing the availability of supplies needed to address this disease.

Proportion of pregnant women screened for hypertensive disorders in pregnancy and its associated factors within antenatal clinics of Kinshasa, Democratic Republic of Congo.

BACKGROUND: Screening for hypertensive disorders in pregnancy (HDP) is clinically important for identifying women at high risk, and planning early preventative interventions to improve pregnancy outcomes. Several studies in developing countries show that pregnant women are seldom screened for HDP. We conducted a study in Kinshasa, DR Congo, in order to assess the proportion of pregnant women screened for HDP, and to identify factors associated with the screening. METHODS: We conducted a facility-based cross-sectional study in a random sample of 580 pregnant women attending the first antenatal visit. Data collection consisted of a review of antenatal records, observations at the antenatal care services, and interviews. A pregnant woman was considered as screened for HDP if she had received the tree following services: blood pressure measurement, urine testing for proteinuria, and HDP risk assessment. Multivariable logistic regression, with generalized estimating equations, was used to identify factors associated with the screening for HDP. RESULTS: Of the 580 pregnant women, 155 (26.7%) were screened for HDP, 555 (95.7%) had their blood pressure checked, 347(59.8%) were assessed for risk factors of HDP, and 156 (26.9%) were tested for proteinuria. After multivariable analysis, screening for HDP was significantly higher in parous women (AOR = 2.09; 95% CI, 1.11-3.99; P = 0.023), in women with a gestational age of at least 20 weeks (AOR = 5.50; 95% CI, 2.86-10.89; P = 0.002), in women attending in a private clinic (AOR = 3.49; 95% CI, 1.07-11.34; P = 0.038), or in a hospital (AOR = 3.24; 95% CI, 1.24-8.47; P = 0.017), and when no additional payment was required for proteinuria testing at the clinic (AOR = 2.39; 95% CI, 1.14-5.02; P = 0.021). CONCLUSION: Our results show that screening for HDP during the first antenatal visit in Kinshasa is not universal. The factors associated with screening included maternal as well as clinics' characteristics. More effort should be made both at maternal and clinic levels to improve the screening for HDP in Kinshasa.

Correlates of Zero-Dose Status among Children Aged 12-23 Months in the Luambo Health District, Democratic Republic of Congo: A Matched Case-Control Study.

(1) Background: "Zero-dose" (ZD) refers to a child who has not received any doses of the pentavalent (diphtheria-tetanus-pertussis-Haemophilus influenzae type b (Hib)-hepatitis B) vaccine. ZD children are vulnerable to vaccine-preventable diseases (VPDs). Luambo health district (HD) is one of 26 HDs in Kasai Central Province in Democratic Republic of the Congo and had the largest number of ZD children in 2021. This study was conducted to identify factors associated with ZD status among children in Luambo HD. (2) Methods: We conducted a mixed-methods study of children aged 12-23 months in Luambo HD. (3) Results: A total of 445 children aged 12-23 months were included in the study, including 89 cases and 356 controls. Children who were born in Angola (AOR = 3.2; 95% CI = 1.1 to 9.8; p = 0.046), born at home (AOR = 5.2; 95% CI = 2.1 to 12.5; p < 0.001), whose mothers did not receive antenatal care (AOR = 4.4; 95% CI = 1.2 to 16.3; p = 0.023), or did not know any vaccine preventable disease (AOR = 13.3; 95% CI = 4.6 to 38.4; p < 0.001) were more likely to be ZD than their counterparts. In addition, perceptions of children's parents influenced child immunization. (4) Conclusions: Factors associated with being a ZD child suggest inequalities in vaccination that need to be addressed through appropriate interventions. Maternal and child health services need to be strengthened while also targeting children's fathers. This will make it possible to considerably reduce the proportion of ZD and undervaccinated children and effectively fight against VPDs.

Political engagement: a key pillar in revitalisation of polio and routine immunisation programmes in the Democratic Republic of the Congo.

Immunisation is a high priority for improving health outcomes. Yet, in many low-income and middle-income countries, achieving coverage targets independently is hindered by lack of domestic resources and reliance on partners' support. Both the 2001 Abuja Declaration and 2016 Addis Declaration were key political commitments to improving immunisation coverage; however, many signatories have yet to meet international targets. Despite signing the Global Vaccine Action Plan and Addis Declaration, the Democratic Republic of the Congo (DRC) was unable to fully disburse its portion of allocated funds to cover vaccines without support from Gavi, the Vaccine Alliance and the World Bank between 2017 and 2019. Additionally, during the same time, vaccine coverage outcomes indicated negative trends, with over 750 000 children considered 'zero-dose' in 2018. In 2019, a primary focus of the then newly elected President's agenda was universal healthcare. In collaboration with development partners and stakeholders, the first Presidential Forum was held as a public commitment to increasing childhood immunisation and ensuring the country remains polio-free. This article seeks to highlight the key outcomes of the Forum such as the signing of the Kinshasa Declaration, which formally set targets and specified national, provincial and community-level commitments to vaccination and polio eradication. As of 2023, three Forums have been conducted to reiterate political commitment to routine immunisation in the DRC. This type of high-level commitment could serve as a template for other countries struggling to have high engagement as targets for polio eradication and strengthened routine immunisation are set for 2025-2030.

Adherence to face mask use during the COVID-19 pandemic among women seeking antenatal care in Kinshasa, Democratic Republic of Congo: a facility-based cross-sectional study.

OBJECTIVES: To describe face mask use among pregnant women seeking antenatal care (ANC) in Kinshasa, Democratic Republic of Congo and to identify factors associated with masking adherence in this population. DESIGN: Facility-based cross-sectional study nested within a prospective cohort study. SETTING: Random sample of 10 health facilities, including 5 primary health centers and 5 secondary facilities or hospitals. PARTICIPANTS: A total of 934 pregnant women aged 18 years or above with a gestational age of at least 32 weeks were consecutively surveyed from 17 August 2020 to 31 January 2021. PRIMARY AND SECONDARY OUTCOME MEASURES: We estimated the proportions of pregnant women wearing a face mask and masking correctly (ie, over the mouth and nose), and assessed their knowledge regarding the COVID-19 pandemic. Multivariable logistic regression was employed to identify factors associated with overall and correct face mask use. RESULTS: Overall, 309 (33.1%) women wore a mask during the interview after their antenatal appointments, but only 33 (10.7%) wore a mask correctly. The odds of masking and correct mask use were significantly higher among women who had their ANC visit in a facility that provided COVID-19 care. Additionally, women who experienced COVID-19-like symptoms in the past 6 months had higher odds of wearing a mask correctly compared with those reporting no recent symptoms. Although 908 (97.2%) women were aware of the COVID-19 pandemic, only 611 (67.3%) thought that COVID-19 was circulating locally in Kinshasa. CONCLUSION: Overall and correct face mask adherence levels were low among pregnant women attending ANC in Kinshasa. Our study highlights the need for improving adherence to correct face mask use in order to help control the spread of COVID-19 within Kinshasa alongside other control measures, like vaccination.

Hesitancy to receive the novel coronavirus vaccine and potential influences on vaccination among a cohort of healthcare workers in the Democratic Republic of the Congo.

Hesitancy to receive the COVID-19 vaccine among healthcare workers (HCWs) in low-resource settings, such as the Democratic Republic of the Congo (DRC), is a major global health challenge. This study identifies changes in willingness to receive vaccination among 588 HCWs in the DRC and reported influences on COVID-19 vaccination intentions. Up to 25 repeated measures were collected from participants between August 2020 to August 2021. Among the overall cohort, between August 2020 and mid-March 2021, the proportion of HCWs in each period of data collection reporting COVID-19 vaccine hesitancy ranged from 8.6% (95% CI: 5.97, 11.24) to 24.3% (95% CI: 20.12, 28.55). By early April 2021, the proportion reporting hesitancy more than doubled (52.0%; 95% CI: 46.22, 57.83). While hesitancy in the cohort began to decline by late-June 2021, 22.6% (95% CI: 18.05, 27.18) respondents indicated hesitancy in late-August 2021 which remains greater than the proportion of hesitancy at any time prior to early-March 2021. Patterns in reported influences on COVID-19 vaccination were varied with the proportion reporting some influences (e.g., no serious side effects, country of vaccine production) remaining stable throughout the year and other factors (e.g., recommendation of Ministry of Health, ease of vaccination) falling in popularity among respondents. Agreement that the national vaccination schedule should be followed apart from the COVID-19 vaccine remained high among respondents throughout the study period. This study shows that, among a cohort of HCWs in the DRC who have likely been influenced by regional, national, and global factors, COVID-19 vaccine hesitancy has fluctuated during the pandemic and should not be treated as a static factor. Additional research to determine which factors most influence HCWs' willingness to receive the COVID-19 vaccine offers opportunities to reduce vaccine hesitancy among this important population through tailored public health messaging.

Factors associated with adherence to COVID-19 prevention measures in the Democratic Republic of the Congo (DRC): results of an online survey.

OBJECTIVES: We aimed to assess the level of adherence to COVID-19 preventive measures in the Democratic Republic of the Congo (DRC) and to identify factors associated with non-adherence. DESIGN: A cross-sectional population-based online survey. SETTINGS: The study was conducted in 22 provinces of the DRC. Five provinces with a satisfactory number of respondents were included in the analysis: Haut Katanga, Kasaï-Central, Kasaï-Oriental, Kinshasa and North Kivu. PARTICIPANTS: The participants were people aged ≥18 years, living in the DRC. A total of 3268 participants were included in the study analysis. INTERVENTIONS: Both convenience sampling (surveyors themselves contacted potential participants in different districts) and snowball sampling (the participants were requested to share the link of the questionnaire with their contacts) methods were used. PRIMARY AND SECONDARY OUTCOME MEASURES: We computed adherence scores using responses to 10 questions concerning COVID-19 preventive measures recommended by the WHO and the DRC Ministry of Health. We used logistic regression analysis with generalised estimating equations to identify factors of poor adherence. We also asked about the presence or absence of flu-like symptoms during the preceding 14 days, whether a COVID-19 test was done and the test result. RESULTS: Data from 3268 participants were analysed. Face masks were not used by 1789 (54.7%) participants. Non-adherence to physical distancing was reported by 1364 (41.7%) participants. 501 (15.3%) participants did not observe regular handwashing. Five variables were associated with poor adherence: lower education level, living with other people at home, being jobless/students, living with a partner and not being a healthcare worker. CONCLUSION: Despite compulsory restrictions imposed by the government, only about half of the respondents adhered to COVID-19 preventive measures in the DRC. Disparities across the provinces are remarkable. There is an urgent need to further explore the reasons for these disparities and factors associated with non-adherence.
