Tetanus Toxoid Injection During Last Pregnancy Among Women in Reproductive Age in Nepal

Tetanus toxoid injection is important as one mandatory vaccine for pregnant women to prevent maternal and neonatal tetanus. This study purposed to examine the barriers of not receiving tetanus toxoid vaccine among women of reproductive age in Nepal. This study used the secondary data using “Multiple Indicators Clusters Survey” round 6 in 2019. Total sample of this study are 2,494 women of reproductive aged 15 to 49 years. The data analysis was done for univariate, bivariate, and multivariate using binary logistic regression. The results in this study revealed that increasing child ever born (CEB) as the main predictor for not receiving TT vaccine, following by higher educational level and wealth index. In conclusion, the TT vaccine is a critical intervention to prevent maternal and neonatal tetanus. Understanding the determinants of TT vaccination coverage, ensuring accessibility to the vaccine, and addressing knowledge gaps among pregnant women are essential for improving TT vaccination rates during pregnancy

Vaccines coverage and associated factors among children aged 12–23 months in the Pawie district, Ethiopia: A cross-sectional study

BackgroundAlthough access to vaccines for children is increasing at healthcare facilities, outbreaks of vaccine preventable diseases and deaths have been reported in different areas of the Benishangul Gumuz region, in Ethiopia. Various interventions have been designed to provide vaccines for each child at an appropriate age. Still there is limited information on full vaccination coverage and associated factors among children aged 12–23 months in the Benishangul-Gumuz region, particularly in the Pawie district. MethodA community-based cross-sectional study design was used from April, 1–30, 2022 among 750 participants. Study populations were selected using a simple random sampling technique. Data was collected using structured questionnaires. Data was coded and entered into the SPSS Statistics 23.0. Bi-variable and multivariate logistic regression analyses were used to assess factors associated with the children vaccination status. Variables with p-value <0.05 were considered significantly associated with the outcome variable. ResultThe results of this study revealed that 542 (72.3 %) (95 % CI: 68.9, 75.2) of the children were fully vaccinated. Factors significantly associated with full vaccination coverage included employed mothers (AOR = 0.53, 95 % CI: 0.29, 0.95), antenatal care (ANC) follow-up (AOR = 1.74, 95 % CI: 1.00, 3.03), post-natal care (PNC) follow-up (AOR = 6.19, 95 % CI: 3.62, 10.56), health institution delivery (AOR = 4.70, 95 % CI: 1.90, 11.66), birth order of children (AOR = 3.63, CI: 2.00, 6.59), maternal tetanus toxoid (TT) vaccination (AOR = 3.05, CI: 1.36, 6.86) and knowledge of vaccination schedule (AOR = 2.49, 95 % CI: 1.19, 5.21). ConclusionsThis study revealed that among children aged 12–23 months, full vaccination coverage was notably low. Factors significantly associated with higher rates of full vaccination included mothers’ occupation, attendance at ANC visits, PNC visits, birth order of children, place of delivery, maternal awareness of vaccination schedules, and maternal TT vaccination status. These findings highlight the multifaceted influences of maternal characteristics, healthcare use patterns, and maternal knowledge on childhood vaccination in this population.

A Ten-Year Review of Neonatal Tetanus Seen in a Tertiary Health Facility in Sokoto North-Western Nigeria: Before and During the Covid-19 Pandemic

Background: Neonatal tetanus (NNT) remains among the leading cause of preventable morbidity and mortality among neonates in Nigeria. Nigeria remains among the countries carrying the global NNT burden. At the onset of the COVID-19 pandemic, reports have predicted that the pandemic will significantly impact on the health system globally, and low-resource countries where vaccination programs fared even worse are likely to see a surge in vaccine-preventable diseases during and after COVID-19 pandemic. Aims: To determine the prevalence, yearly trend, risk factors, and outcome of NNT cases seen in the Special Care Baby Unit (SCBU) of Usmanu Danfodiyo University Teaching Hospital (UDUTH), Sokoto, Nigeria over a ten year period: before and during COVID-19 pandemic. Methods: This was a retrospective study. Data was retrieved from all the case notes of neonates admitted with a clinical diagnosis of NNT into the SCBU of the UDUTH, Sokoto from 1st January, 2013 to 31st December, 2022. The data obtained was analyzed using SPSS version 21. Results: During the 10 years period of the study, NNT accounted for 0.4% of admissions. The majority 15(57.0%) of the mothers of the neonates with NNT were from rural areas, 15(56.0%) had no antenatal care (ANC), and only 10(37.0%) of the mothers received vaccination against tetanus. All the mothers were from lower socio-economic classes. Most 17(63.0%) of the neonates were delivered at home by traditional birth attendants. The umbilical cord was the portal of entry in 26(96.0%) of cases, while 1(4.0%) followed traditional uvulectomy. Cord care was done using hot water fermentation in more than half of the neonates 17(63.0%), while only 1(4.0%) of the mothers used chlorhexidine gel for cord care. The case- fatality rate was 6(22.0%). the yearly trend showed an increased incidence of NNT admissions in 2022. Conclusion: The study showed that NNT is still a public health problem, with an increased scourge during the COVID-19 pandemic, which can be tackled through health education of mothers via mass media, improving the quality and access to ANC services, tetanus toxoid vaccination, hospital delivery and avoidance of traditional uvulectomy particularly in rural areas by the Sokoto state government. Antenatal and vaccination services should be given priority in response to future pandemics to sustain gains of the SDG 3.

Vaccine-Induced Immunity Against Pertussis in Lung Transplant Candidates

Background. Given the high prevalence of Bordetella pertussis, patients with respiratory disorders are at risk of getting infected with this pathogen and developing pertussis. Therefore, they should be considered a target group for vaccination against this infection. Aims — the objective of the study was to assess vaccine-induced immunity against pertussis in lung transplant candidates. Methods. Twenty-four patients with severe bronchopulmonary diseases, aged 18 to 60, were vaccinated against pertussis with Diphtheria and Tetanus Toxoids and Acellular Pertussis Vaccine. Five patients underwent lung transplantation. Immunoglobulin G (IgG) antibodies (Abs) were measured using the RIDASCREEN® Bordetella IgG test system. Results. In the post-vaccination period, only 8.3% of the patients developed such local reactions as tenderness and induration at the injection site. The proportions of patients who were seropositive for pertussis before vaccination, one month and one year after vaccination were 71, 100 and 100%, respectively (p = 0.02). A significant increase in anti-pertussis IgG Ab levels was identified one month after a single vaccine dose, and was still observed after 12 months. In the group of two-dose vaccination, there was no statistical difference between the levels of IgG Abs one month after the first dose and one month after the second dose. A significant increase in anti-Bordetella pertussis IgG Ab levels was observed in the group of initially seronegative patients compared to seropositive patients (p = 0.03). A year after vaccination, there was no statistically significant difference in IgG Ab levels between the patients with and without a history of lung transplantation. Conclusions. The majority (71%) of patients with severe bronchopulmonary disease was seropositive for B. pertussis. Single-dose vaccination against pertussis was safe; it induced the production of additional specific Abs and an increase in their levels in all patients. Therapy administered after lung transplantation did not significantly affect the levels of vaccine-induced Abs.

Uptake and Determinants of Tetanus Vaccination among Female Clinical Medical Students in North-Western Nigeria

Background and Aim: Neonatal and maternal tetanus have remained endemic in tropical countries of Asia and Africa, with high fatality. Vaccination of women of childbearing age is the main strategy for their prevention/elimination. However, the uptake of these vaccines among these women has remained dismally low in these parts of the world. This study looked at the uptake and determinants of tetanus vaccination among the female clinical medical students of Bayero University, Kano, purposely looking at the interplay between knowledge and other factors on vaccine uptake. Materials and Methods: This was a cross-sectional study of female medical students aged 15–45 years, selected using probability proportionate to size and simple random sampling. The required information was collected using a validated semi-structured questionnaire. The data were analyzed using the Statistical Product and Service Solutions (SPSS) for Windows version 23. Prevalences of tetanus vaccination were calculated. The presence of a statistically significant difference in prevalence and other characteristics of the study groups were determined using appropriate tests. P &lt;0.05 was considered statistically significant. Results: The participants were 140 with the mean age and mean knowledge scores of 23.96 (±2.74) years and 6.61 (±2.47), respectively. Most of them (59.3%) had good knowledge score (&gt;7). The prevalence of tetanus toxoid (TT)1 and TT2 was 20.7% and 17.1%, respectively. Being married, ever pregnant, and higher level of study were significantly associated with being vaccinated (χ2 / P =59.093/P &lt;0.001, P = 65.011/P &lt;0.001, and P = 9.860/P =0.020, respectively). Conclusions: Despite the good knowledge of the vaccination, the uptake of TT vaccination among clinical female students was poor. Factors significantly associated with higher vaccine uptake were marital status, age of the participants, and their class of study.

Abstract CT108: Phase I data from TENDU101, a first-in-human trial of a novel synthetic peptide conjugate cancer vaccine platform assessed in recurrent prostate cancer patients before salvage treatment

Abstract Synthetic peptides are explored in the clinic in cancer vaccine development for the purpose of inducing tumor-directed T cell responses. Their immunogenicity is dependent on the chosen adjuvant and target organ exposure (lymphoid organs). To improve peptide immunogenicity, we have developed a technology enabling cross-linking of endogenous, pre-existing circulating antibodies (Abs) by employing a three-dimensional chemistry design. Multiple identical tetanus toxin-derived B cell epitopes (MTTEs) are conjugated to synthetically made antigenic tumor peptides intended to induce T cell responses. Here we report the first clinical safety assessment of the vaccine platform in the trial TENDU101 (NCT04701021). The cancer vaccine candidate (TENDU) was designed to include longer synthetic peptides harboring prostate cancer derived epitopes (CD4 and CD8) from PAP and PSMA. The study was a 3+3 design and doses were 40, 400 and 960 microgram in patients with documented recurrent disease after radical prostatectomy. A tetanus toxoid (TTd) containing vaccine boost was followed by TENDU vaccination via subcutaneous injection in the abdomen (4 doses in total with a 2 week interval) in n=9 patients (gr 1, 2, 3.1). For group 3.2 (n=3) TENDU vaccination was administrated in the same arm as the TTd vaccination. Primary objective was safety and secondary objective assessment of immune responses and preliminary anti-tumor responses. A total of 52 adverse events (AEs) were reported, most mild and deemed unrelated to vaccination. Six treatment-related AEs were reported of which 50% were mild transient injection site reactions in a single patient (gr 3.1), and three events of increases in lipase levels in two patients (gr 2). No serious AEs was reported. T cell responses pre/post TENDU were assessed in a total of six patients of which five patients displayed increased response against vaccine-related CD8 and CD4 epitopes (ELISpot). The three patients with the greatest increase in T cell responses were found to display the highest anti-MTTE IgG responses. A trend towards decrease in circulating tumor cells from screening to the end of treatment visit was observed in the patients with the highest levels of anti-MTTE IgGs post TENDU vaccination. There were no trends for decrease in PSA and/or PAP at the end of treatment and follow-up measurements were affected by initiation of radiation and short-term androgen deprivation. The administration of TTd and TENDU to the same anatomical location although spaced in time appeared to negatively influence immune responses to TTd and TENDU. In conclusion, the novel synthetic peptide conjugate vaccine conjugate was found safe with no serious AEs reported and a positive correlation between anti-MTTE and T cell responses was noted in patients when TENDU was administrated in the abdomen.

Assessing risk perceptions that contribute to tetanus toxoid maternal vaccine hesitancy in Kilifi County, Kenya

Background Vaccination is one of the most effective public health interventions today. However, a growing number of people perceive vaccines as unsafe and unnecessary. Methods We used a mixed method research in which we administered a quantitative survey to men and women of reproductive age, held Focus Group Discussions (FGDs) with expectant mothers, and interviewed Key Informants (KI) to understand maternal vaccine hesitancy within a rural setting of Kilifi County, Kenya. Results Of the 104 people surveyed, 70% of the participants were aware of the vaccine that expectant women receive, with 26% stating that they know people in their community who have refused or were hesitant to take maternal vaccination. Reasons for refusals include religion and rumours that have spread in the community that the tetanus toxoid vaccine was a family planning method. Stockout of the vaccine was identified as one of the healthcare factors affecting vaccine uptake. Healthcare workers were the most trusted source for information about maternal vaccines. Conclusion Dissemination of accurate information and continuous engagement with community members can build trust and confidence in maternal vaccines.

Receipt of core antenatal care components and associated factors in Ethiopia: a multilevel analysis.

Despite recent promising progress, maternal morbidity and mortality are still unacceptably high in Ethiopia. This is partly attributed to the lack of quality health services. Pregnant women may not receive adequate services that are essential to protect the health of women and their unborn children. This study aimed to examine the extent of receiving prenatal care components and associated factors in Ethiopia. It also assessed prenatal service use inequality between urban and rural residents. The analysis was carried out using the 2016 Ethiopian Demographic and Health Survey (EDHS), which is nationally representative survey data. A weighted sample of 4,772 women nested within 595 communities who had live births five years preceding the survey was included in the study. Necessary adjustments were made to account for the design of the survey, and sampling weights were used to adjust for nonproportional allocation of the sample to strata. Bivariate and multivariable multilevel ordered logit models were used to analyze factors associated with receiving comprehensive ANC contents. Statistically significant predictors were identified at p value ≤ 0.05. Among those women who had at least one ANC visit, only 15% (95% CI: 13, 16) received six core elements of antenatal care. The proportion of mothers who had essential prenatal components in rural areas was less than 13 percentage points. Approximately 43% of women did not receive at least two doses of tetanus toxoid vaccines to protect them and newborn infants against this life-threatening disease. Moreover, the majority of them, particularly those in rural Ethiopia, were not informed about pregnancy danger signs. Mothers who had at least four ANC visits received more types of prenatal components compared to those who had fewer ANC visits. The multilevel regression analysis revealed that receiving adequate ANC content is positively associated with having more frequent ANC visits, attaining a higher education level, being a member of a household in the highest wealth quintile and residing in urban areas. The evidence implies that the quality of maternal health services needs to be improved. Health programs and interventions should also give priority to rural areas where the majority of Ethiopian women reside.

DENTIST’S ROLE IN COLLABORATIVE MANAGEMENT OF TETANUS PATIENT

Tetanus was a life-threatening infection causing muscle contractions. The need for qualified collaborative management was crucial due to the potential for poor prognosis and complications. Dentists can contribute significantly to the treatment, as the mouth can be one of the entry points for tetanus-causing bacteria. A 45-year-old male tetanus inpatient was referred from the Intensive Care Unit to the Oral Medicine Unit at Universitas Indonesia Hospital to evaluate the possible source of oral focus infection. A boil was on his back, suspected to be the main port of entry for tetanus bacteria. The definitive diagnosis was Tetanus of moderate to severe severity (Philips score 24, Dakar score 1, Ablett score 2). Extra oral examination shows lip inflammation. An intra-oral examination cannot be done optimally despite his trismus. The oral foci of infection found were chronic gingivitis and pulp necrosis on 47 48, in addition to the diagnosis of cheilitis simplex. Since the comprehensive management of the foci of infection could only be done in an outpatient setting, the nurse was instructed to clean the intra-oral using sterile gauze moistened with NaCl 0.9% solution to improve the patient's oral hygiene (OH). Comprehensive management includes periodically visiting to maintain OH, administering muscle relaxants, antibiotics, and analgesics, and administering Tetanus toxoid vaccination. The patient was recovered. Management of tetanus cases needs a multidisciplinary approach. Dentists are pivotal in identifying oral infection sources and ensuring its management. A dentist's role in the collaborative management of tetanus patients might significantly contribute to the patient's prognosis.

Efficacy of typhoid conjugate vaccine: final analysis of a 4-year, phase 3, randomised controlled trial in Malawian children

Randomised controlled trials of typhoid conjugate vaccines among children in Africa and Asia have shown high short-term efficacy. Data on the durability of protection beyond 2 years are sparse. We present the final analysis of a randomised controlled trial in Malawi, encompassing more than 4 years of follow-up, with the aim of investigating vaccine efficacy over time and by age group. In this phase 3, double-blind, randomised controlled efficacy trial in Blantyre, Malawi, healthy children aged 9 months to 12 years were randomly assigned (1:1) by an unmasked statistician to receive a single dose of Vi polysaccharide conjugated to tetanus toxoid vaccine (Vi-TT) or meningococcal capsular group A conjugate (MenA) vaccine. Children had to have no previous history of typhoid vaccination and reside in the study areas for inclusion and were recruited from government schools and health centres. Participants, their parents or guardians, and the study team were masked to vaccine allocation. Nurses administering vaccines were unmasked. We did surveillance for febrile illness from vaccination until follow-up completion. The primary outcome was first occurrence of blood culture-confirmed typhoid fever. Eligible children who were randomly assigned and vaccinated were included in the intention-to-treat analyses. This trial is registered at ClinicalTrials.gov, NCT03299426. Between Feb 21, 2018, and Sept 27, 2018, 28 130 children were vaccinated; 14 069 were assigned to receive Vi-TT and 14 061 to receive MenA. After a median follow-up of 4·3 years (IQR 4·2-4·5), 24 (39·7 cases per 100 000 person-years) children in the Vi-TT group and 110 (182·7 cases per 100 000 person-years) children in the MenA group were diagnosed with a first episode of blood culture-confirmed typhoid fever. In the intention-to-treat population, efficacy of Vi-TT was 78·3% (95% CI 66·3-86·1), and 163 (129-222) children needed to be vaccinated to prevent one case. Efficacies by age group were 70·6% (6·4-93·0) for children aged 9 months to 2 years; 79·6% (45·8-93·9) for children aged 2-4 years; and 79·3% (63·5-89·0) for children aged 5-12 years. A single dose of Vi-TT is durably efficacious for at least 4 years among children aged 9 months to 12 years and shows efficacy in all age groups, including children younger than 2 years. These results support current WHO recommendations in typhoid-endemic areas for mass campaigns among children aged 9 months to 15 years, followed by routine introduction in the first 2 years of life.

Hotspot areas of tetanus-unprotected births and its associated factors in Ethiopia: Spatial analysis of EDHS data

ABSTRACT Neonatal tetanus persists as a public health problem in many developing countries including Ethiopia. Maternal tetanus toxoid vaccination is a cornerstone to prevent neonatal tetanus. However, its prevalence is low in Ethiopia, and little has been devoted to its spatial epidemiology and associated factors. Hence, this study aimed to explore the spatial pattern and factors affecting tetanus-unprotected births in Ethiopia. A further analysis of the 2016 Ethiopia Demographic and Health Survey data was conducted, and a weighted sample of 7590 women was used for analysis. Spatial analysis was done using ArcGIS and SaTScan software. A binary logistic regression model was fitted to identify factors and variables with a p-value <.05 were considered as statistically significant. About 54.13% (95% CI: 53.01, 55.25) of births were not protected against neonatal tetanus, and spatial clustering of tetanus unprotected births was observed (Moran’s I = 0.144, p-value = .028). The primary and secondary SaTScan clusters were detected in Northeastern Tigray, Eastern Amhara, and almost the entire Afar (RR = 1.34 & LLR = 66.5, p < .01), and in the Somali region, and the western border of Gambela (RR = 1.44 & LLR = 31.3, p < .01), respectively. Tetanus unprotected births were higher among women without formal education (AOR = 1.63; 95% CI: 1.29, 2.04), came from poor households (AOR = 1.27; 95% CI: 1.12, 1.45), who had no ANC contact (AOR = 6.97; 95% CI: 6.21, 7.88), and who were not exposed to the media (AOR = 1.26; 95% CI: 1.09, 1.47). Hence, tetanus-unprotected birth hotspots require priority interventions, and it is good if the targeted interventions consider the identified factors.

Uptake of protective tetanus toxoid vaccine doses and maternal associated factors during pregnancy in armed conflict zone, hospital-based cross-sectional study.

Vaccinating pregnant women with tetanus toxoid (TT) is crucial to prevent neonatal tetanus, reducing related deaths by 94%. In conflict zones with restricted access to deliveries, neonates face a fatality rate of 80%-100%. This study explores the uptake of protective TT vaccine doses and maternal associated factors during pregnancy in an armed conflict zone. A hospital-based, descriptive, cross-sectional study was conducted of 357 pregnant women at delivery using simple random sampling. Data were collected through interviews with a structured questionnaire, and entered using Epi-data version 3.1, and exported using SPSS version 22 for further analysis. Binary and multivariable logistic regression analyses were used to identify significant variables for receiving protective TT doses during pregnancy at P < 0.05. In this study, 355 pregnant women were included, with response rate of 99.4%. The mean age of the participants was 27.65 ± 6.23 years. During the study period, 67.3% of pregnant women received a protective TT vaccine dose while 33.3% were missed due to escalated armed conflict. The dropout rates were significant from TT5 to TT2 (17.6%), TT5 to TT3 (11.9%), and TT5 to TT4 (6.1%). However, maternal associated factors for the uptake of the TT protective vaccine dose were identified, including being aged 36-49 years [adjusted odds ratio (AOR) = 3.7; 95% confidence interval (CI) 1.54-7.8; P = 0.001], completing high school (AOR = 3.05; 95% CI 1.5-8.9; P = 0.02), having an antenatal care follow-up (AOR = 9.4; 95% CI 2.9-24.3; P = 0.001), previous media exposure (AOR = 15.5; 95% CI 7.5-25.3; P = 0.001), and good maternal knowledge (AOR = 2.7; 95% CI 1.8-4.9; P = 0.02). The uptake of the protective TT vaccine dose among pregnant women in a continued armed conflict area was low compared with previous study findings. Efforts should be made to increase vaccine uptake and reduce dropout rates by addressing both community and individual-level factors.

Safety and immunogenicity of an indigenously developed tetanus toxoid, diphtheria toxoid, and acellular pertussis vaccine (Tdap) in adults, adolescents, and children in India

ABSTRACTBackgroundThis study assessed safety and immunogenicity of Serum Institute of India Pvt Ltd (SIIPL)’s tetanus toxoid (TT), diphtheria toxoid (DT), and acellular pertussis booster vaccine (Tdap).Research Design and MethodsIn this Phase II/III, multicenter, randomized, active-controlled, open-label study, 1500 healthy individuals, aged 4–65 years, were randomized to receive a single dose of SIIPL Tdap or comparator Tdap vaccine (Boostrix®; GlaxoSmithKlines, India). Adverse events (AEs) during initial 30 minutes, 7-day, 30-day post-vaccination were assessed. Blood samples were taken before and 30 days post-vaccination for immunogenicity assessment.ResultsNo significant differences in incidence of local and systemic solicited AEs were observed between the two groups; no vaccine-related serious AEs were reported. SIIPL Tdap was non-inferior to comparator Tdap in achieving booster responses to TT and DT in 75.2% and 70.8% of the participants, respectively, and to pertussis toxoid (PT), pertactin (PRN), and filamentous hemagglutinin (FHA) in 94.3%, 92.6%, and 95.0% of the participants, respectively. Anti-PT, anti-PRN, and anti-FHA antibody geometric mean titers in both the groups, were significantly higher post-vaccination compared to pre-vaccination.ConclusionsBooster vaccination with SIIPL Tdap was non-inferior to comparator Tdap with respect to immunogenicity against tetanus, diphtheria, and pertussis and was well tolerated.

Prevalence and correlates of tetanus toxoid uptake among women in sub-Saharan Africa: Multilevel analysis of demographic and health survey data.

Tetanus toxoid vaccination is one of the most effective and protective measures against tetanus deaths among mothers and their newborns. We examined the prevalence and correlates of tetanus toxoid uptake among women in sub-Saharan African (SSA). We analysed pooled data from the Demographic and Health Surveys (DHS) of 32 countries in SSA conducted from 2010 to 2020. We included 223,594 women with a history of childbirth before the survey. Percentages were used to present the prevalence of tetanus toxoid vaccine uptake among the women. We examined the correlates of tetanus toxoid uptake using a multilevel binary logistic regression. The overall prevalence of tetanus toxoid uptake was 51.5%, which ranged from 27.5% in Zambia to 79.2% in Liberia. Women age, education level, current working status, parity, antenatal care visits, mass media exposure, wealth index, and place of residence were the factors associated with the uptake of tetanus toxoid among the women. Uptake of tetanus toxoid vaccination among the women in SSA was low. Maternal age, education, current working status, parity, antenatal care visits, exposure to mass media, and wealth status influence tetanus toxoid uptake among women. Our findings suggest that health sector stakeholders in SSA must implement interventions that encourage pregnant women to have at least four antenatal care visits. Also, health policymakers in SSA could ensure that the tetanus toxoid vaccine is free or covered under national health insurance to make it easier for women from poorer households to have access to it when necessary.

Contents of antenatal care services in Afghanistan: findings from the national health survey 2018

BackgroundMaternal and newborn mortality is a public health concern in low- and middle-income countries (LMICs), including Afghanistan, where the evolving socio-political circumstances have added new complexities to healthcare service delivery. Birth outcomes for both pregnant women and their newborns are improved if women receive benefits of quality antenatal care (ANC).ObjectivesThis study aimed to assess the contents of ANC services and identify predictors of utilization of services by pregnant women during ANC visits to health facilities in Afghanistan.MethodsIn this cross-sectional study, we used data from the Afghanistan Health Survey 2018 (AHS2018). We included a total of 6,627 ever-married women, aged 14–49 years, who had given birth in the past 2 years or were pregnant at the time of survey and had consulted a health worker for ANC services in a health facility. The outcome was defined as 1–4 services and 5–8 services that a pregnant woman received during an ANC visit. The services were (i) taking a pregnant woman’s blood pressure, (ii) weighing her, (iii) testing her blood, (iv) testing her urine, (v) providing advice on nutrition, (vi) advising about complicated pregnancy, (vii) advising about the availability of health services, and (viii) giving her at least one dose of Tetanus Toxoid (TT) vaccine. The binary outcome (1–4 services versus 5–8 services) was used in a multivariable logistic regression model.ResultsOf all 6,627 women, 31.4% (2,083) received 5–8 services during ANC visits. Only 1.3% (86) received all 8 services, with 98.7% (6,541) receiving between 1 and 7 services, and 71.6% (4,745) women had their blood pressure measured during ANC visits. The likelihood (adOR = Adjusted Odds Ratio) of receiving 5–8 services was higher in women who could read and write (adOR = 1.33: 1.15–1.54), in women whose husbands could read and write (adOR = 1.14: 1.00-1.28), in primipara women (adOR = 1.42: 1.02–1.98), in women who knew one danger sign (adOR = 5.38: 4.50–6.45), those who knew 2 danger signs (adOR = 8.51: 7.12–10.19) and those who knew ≥ 3 danger signs (adOR = 13.19: 10.67–16.29) of complicated pregnancy, and in women who had almost daily access to TV (adOR = 1.16: 1.01–1.33). However, the likelihood of receiving 5–8 services was lower in women who used private clinics (adOR = 0.64: 0.55–0.74) and who received services from nurses (adOR = 0.27 (0.08–0.88).ConclusionOur findings have the potential to influence the design and implementation of ANC services of health interventions to improve the delivery of services to pregnant women during ANC visits.

Multilevel and subnational analysis of the predictors of maternity continuum of care completion in Nigeria: a cross-sectional survey

Understanding population discrepancy in maternity continuum of care (CoC) completion, particularly in sub-Saharan Africa is significant for interventional plan to achieve optimal pregnancy outcome and child survival. This study thus investigated the magnitudes, distribution, and drivers of maternity CoC completion in Nigeria. A secondary analysis of 19,474 reproductive age (15–49 years) women with at least a birth (level 1) in 1400 communities (level 2) across 37 states covered in the 2018 cross-sectional survey. Stepwise regression initially identified important variables at 10% cutoff point. Multilevel analysis was performed to determine the likelihood and significance of individual and community factors. Intra-cluster correlation assessed the degree of clustering and deviance statistics identified the optimal model. Only 6.5% of the women completed the CoC. Completion rate is significantly different between communities “4.3% in urban and 2.2% in rural” (χ2 = 392.42, p < 0.001) and was higher in southern subnational than the north. Education (AOR = 1.61, 95% CI 1.20–2.16), wealth (AOR = 1.73, 95% CI 1.35–2.46), media exposure (AOR = 1.22, 95% CI 1.06–1.40), women deciding own health (AOR = 1.37, 95% CI 1.13–1.66), taking iron drug (AOR = 1.84, 95% CI 1.43–2.35) and at least 2 dose of tetanus-toxoid vaccine during pregnancy (AOR = 1.35, 95% CI 1.02–1.78) are associated individual factors. Rural residency (AOR = 1.84, 95% CI = 1.43–2.35), region (AOR = 1.84, 95% CI 1.43–2.35) and rural population proportion (AOR = 1.84, 95% CI 1.43–2.35) are community predictors of the CoC completion. About 63.2% of the total variation in CoC completion was explained by the community predictors. Magnitude of maternity CoC completion is generally low and below the recommended level in Nigeria. Completion rate in urban is twice rural and more likely in the southern than northern subnational. Women residence and region are harmful and beneficial community drivers respectively. Strengthening women health autonomy, sensitization, and education programs particularly in the rural north are essential to curtail the community disparity and optimize maternity CoC practice.

Prevalence and determinants of two or more doses of tetanus toxoid-containing vaccine immunization among pregnant women in sub-Saharan Africa: Evidence from recent demographic and health survey data

IntroductionTetanus is a major public health problem in low and middle income countries including in sub-Saharan Africa. Tetanus toxoid vaccine immunization during pregnancy is a global strategy against mortality due to maternal and neonatal tetanus. Recent data on tetanus toxoid-containing vaccination during pregnancy provides insight to policymakers for better implementation of the vaccine. Hence, this study aimed to determine prevalence and determinants of immunization with tetanus toxoid containing vaccine among pregnant women in sub-Saharan Africa. MethodsSecondary analysis of the recent demographic and health survey data was done using a sample of 173,032 pregnant women. Stata 14 statistical software was used for analysis and multilevel logistic regression model was applied to determine associated factors of two or more tetanus toxoid-containing vaccine immunization. P-value less than 0.05 for adjusted odds ratio was used to identify factors significantly associated with the outcome. ResultThe prevalence of immunization with two and more doses of tetanus toxoid-containing vaccine in sub-Saharan Africa was found to be 49.8 %. Women’s age 36–49, women’s education, poor household wealth index, unwanted pregnancy, women’s occupation, husband education, and community illiteracy were significantly associated with two or more doses of tetanus toxoid-containing vaccine immunization in sub-Saharan Africa. ConclusionIn sub-Saharan Africa, less than half of pregnant women were immunized with two or more doses of tetanus toxoid-containing vaccine. Women's education and women's employment positively affected immunization with two or more doses of tetanus toxoid-containing vaccine. Women’s age group of 36–49 years, unwanted pregnancy, poor household wealth index, husbands having no formal education, and community illiteracy negatively affected receipt of two or more doses of tetanus toxoid-containing vaccine. Therefore, policymakers should take into account the determinants of tetanus toxoid immunization throughout its implementation so as to boost the coverage of tetanus toxoid immunization in sub-Saharan Africa.

Impact of digital intervention on antenatal paper records: results from audit of antenatal records

Abstract Background Good recordkeeping is important in antenatal care (ANC). The mIRA study aimed to improve ANC quality through tablet-based electronic decision support systems (EDSS). Electronic data entry was implemented alongside existing paper-based ANC records, adding an additional record-keeping requirement for health care providers. This study assesses the impacts of the EDSS on paper-based ANC records. Methods The audit was conducted in 19 primary healthcare facilities in Nepal. We examined pregnant women's records before (n = 136) and after (n = 138) EDSS implementation. For eight selected indicators in the ANC card and ANC register, we estimated the percentage completeness (any value recorded) and agreement (whether values matched), comparing results before and after intervention, additionally examining EDSS records. Results Completeness of paper ANC records was high before intervention (&amp;gt;90% for all indicators, except for tetanus toxoid vaccination). There was general trend towards variables being more complete after implementation of the EDSS for both the ANC card and the ANC register. There was &amp;gt;15% improvement in completeness and in agreement of tetanus toxoid vaccination date records in ANC cards and ANC registers after the intervention. Completeness of variables in the EDSS was low, suggesting recordkeeping in ANC cards and ANC registers was prioritized. Percentage agreement increased slightly in all eight indicators after intervention. Amongst the selected eight indicators, only women's age records showed &amp;gt;90% agreement both before and after the intervention. Conclusions EDSS did not have a negative impact on paper-based ANC records. Digital records are widely being used in high-income countries and the increasing implementation of electronic health records in low-resource settings increases the demand for evidence to understand the feasibility and impacts of digital health interventions in real-world settings. Key messages • The additional recordkeeping required by the EDSS resulted in general improvements in the completeness and agreement of ANC paper records. • Large-scale EDSS implementation should consider how to integrate digital and paper-based records to decrease burden on healthcare providers, and improve the standard of records.
