RESUMO
OBJECTIVES: Low-middle income countries, such as Vietnam have a greater burden from stroke than high-income countries. Few health professionals have stroke specialist training, and the quality of care may vary between hospitals. To support improvements to stroke care, we aimed to gain a better understanding of the resources available in hospitals in Vietnam to manage acute stroke. MATERIALS AND METHODS: The survey questions were adapted from the Australian Organisational Survey of Stroke Services (Stroke Foundation). The final 65 questions covered the topics: hospital size and admissions for stroke; use of clinical protocols and assessments conducted; team structure and coordination; communication and team roles. The survey was distributed electronically or via paper form in Vietnamese to clinical leaders of 91 eligible hospitals (November-December 2020). Data were summarised descriptively. RESULTS: Sixty-six (73%) hospitals responded, and doctors predominately completed the survey (98%). Approximately 70% of hospitals had a stroke unit; median 630 acute strokes/year (IQR: 250-1200) and >90% used stroke clinical protocols. The daytime nurse-patient ratio was 1:4. There was a perceived lack of access to allied health staff, including psychologists/neuropsychologists, occupational therapists, and speech pathologists. Only 50% reported having a standardised rehabilitation assessment process. CONCLUSIONS: This is the first large-scale cross-sectional, national overview of stroke services in Vietnam. Future research should include a systematic clinical audit of stroke care to confirm aspects of the data from these hospitals. Repeating the survey in future years will enable the tracking of progress and may influence capacity building for stroke care in Vietnam.

OBJECTIVES: Pregnant women and new mothers are among the most vulnerable to seasonal influenza; however, little is known about their preferences for flu vaccination. We examined the rural-urban differences in uptake, demand and willingness to pay (WTP) for influenza vaccination among women of childbearing age, to assess the feasibility of implementing locally produced vaccines in Vietnam. METHODS: A cross-sectional study was performed in both urban and rural areas of Hanoi in 2018. Socio-demographic characteristics, history of vaccination, demand and WTP for influenza vaccines were obtained. A multivariate logistic regression model was employed to identify the associated factors. RESULTS: Of 750 participants, 29.9% had had flu shots in the current or previous flu season and 64.3% indicated demand for this vaccine. The median of the maximum amount of WTP for influenza vaccination services was US$ 8.5 (IQR: 8.5-17.0). Women living in rural areas had a significantly lower uptake and higher demand, and were willing to pay less than women in urban locations (21.1% vs. 36.6%; 69% vs. 60.2%; and US $8.5 vs. US $11.7, respectively). For urban participants, factors associated with higher demand and WTP for flu shots included having ANC in health facilities and having been vaccinated against influenza in the past; for rural women, these factors were having suffered from influenza and hearing about it. CONCLUSIONS: This study informs the feasibility of implementing locally produced influenza vaccines in Vietnam. Educational programs, along with counselling services and government subsidies, should be implemented to improve the coverage, demand and WTP for the vaccine.
OBJECTIFS: Les femmes enceintes et les nouvelles mères sont parmi les plus vulnérables à la grippe saisonnière; cependant, on en sait peu sur leurs préférences pour la vaccination contre la grippe. Nous avons examiné les différences entre les zones rurales et urbaines dans l'adoption, la demande et la volonté de payer pour la vaccination antigrippale chez les femmes en âge de procréer, afin d'évaluer la faisabilité de la mise en Åuvre de vaccins produits localement au Vietnam. MÉTHODES: Une étude transversale a été réalisée dans les zones urbaines et rurales de Hanoi en 2018. Les caractéristiques sociodémographiques, les antécédents de vaccination, la demande et la volonté de payer pour les vaccins antigrippaux ont été obtenus. Un modèle de régression logistique multivariée a été utilisé pour identifier les facteurs associés. RÉSULTATS: Sur 750 participantes, 29,9% s'étaient fait vacciner contre la grippe au cours de la saison grippale actuelle ou précédente, 64,3% ont indiqué une demande pour ce vaccin. La médiane du montant maximal de la volonté de payer pour les services de vaccination contre la grippe était de 8,5 USD (IQR: 8,5 à 17,0). Les femmes vivant dans les zones rurales avaient une adoption nettement plus faible, une demande plus élevée et étaient prêtes à payer moins que les femmes des zones urbaines (21,1% contre 36,6%; 69% contre 60,2%; et 8,5 USD contre 11,7 USD, respectivement). Pour les participantes urbaines, les facteurs associés à une demande plus élevée et à la volonté de payer pour les vaccins contre la grippe comprenaient le fait d'avoir des soins prénatals dans les établissements de santé et d'avoir été vaccinés contre la grippe dans le passé; pour les femmes rurales, ces facteurs comprenaient, avoir souffert de la grippe et en avoir entendu parler. CONCLUSIONS: Cette étude informe sur la faisabilité de la mise en Åuvre de vaccins antigrippaux produits localement au Vietnam. Des programmes éducatifs, ainsi que des services de conseil et des subventions gouvernementales devraient être mis en Åuvre pour améliorer la couverture, la demande et la volonté de payer pour le vaccin.

BACKGROUND AND PURPOSE: Many patients receiving thrombolysis for acute ischemic stroke are on prior antiplatelet therapy (APT), which may increase symptomatic intracerebral hemorrhage risk. In a prespecified subgroup analysis, we report comparative effects of different doses of intravenous alteplase according to prior APT use among participants of the international multicenter ENCHANTED study (Enhanced Control of Hypertension and Thrombolysis Stroke Study). METHODS: Among 3285 alteplase-treated patients (mean age, 66.6 years; 38% women) randomly assigned to low-dose (0.6 mg/kg) or standard-dose (0.9 mg/kg) intravenous alteplase within 4.5 hours of symptom onset, 752 (22.9%) reported prior APT use. Primary outcome at 90 days was the combined end point of death or disability (modified Rankin Scale [mRS] scores, 2-6). Other outcomes included mRS scores 3 to 6, ordinal mRS shift, and symptomatic intracerebral hemorrhage by various standard criteria. RESULTS: There were no significant differences in outcome between patients with and without prior APT after adjustment for baseline characteristics and management factors during the first week; defined by mRS scores 2 to 6 (adjusted odds ratio [OR], 1.01; 95% confidence interval [CI], 0.81-1.26; P=0.953), 3 to 6 (OR, 0.95; 95% CI, 0.75-1.20; P=0.662), or ordinal mRS shift (OR, 1.03; 95% CI, 0.87-1.21; P=0.770). Alteplase-treated patients on prior APT had higher symptomatic intracerebral hemorrhage (OR, 1.82; 95% CI, 1.00-3.30; P=0.051) according to the safe implementation of thrombolysis in stroke-monitoring study definition. Although not significant (P-trend, 0.053), low-dose alteplase tended to have better outcomes than standard-dose alteplase in those on prior APT compared with those not using APT (mRS scores of 2-6; OR, 0.84; 95% CI, 0.62-1.12 versus OR, 1.16; 95% CI, 0.99-1.36). CONCLUSIONS: Low-dose alteplase may improve outcomes in thrombolysis-treated acute ischemic stroke patients on prior APT, but this requires further evaluation in a randomized controlled trial.

BACKGROUND: As the COVID-19 pandemic evolves, challenges in frontline work continue to impose a significant psychological impact on nurses. However, there is a lack of data on how nurses fared compared to other health care workers in the Asia-Pacific region. OBJECTIVE: This study aims to investigate (1) the psychological outcome characteristics of nurses in different Asia-Pacific countries and (2) psychological differences between nurses, doctors, and nonmedical health care workers. METHODS: Exploratory data analysis and visualization were conducted on the data collected through surveys. A machine learning modeling approach was adopted to further discern the key psychological characteristics differentiating nurses from other health care workers. Decision tree-based machine learning models (Light Gradient Boosting Machine, GradientBoost, and RandomForest) were built to predict whether a set of psychological distress characteristics (ie, depression, anxiety, stress, intrusion, avoidance, and hyperarousal) belong to a nurse. Shapley Additive Explanation (SHAP) values were extracted to identify the prominent characteristics of each of these models. The common prominent characteristic among these models is akin to the most distinctive psychological characteristic that differentiates nurses from other health care workers. RESULTS: Nurses had relatively higher percentages of having normal or unchanged psychological distress symptoms relative to other health care workers (n=233-260 [86.0%-95.9%] vs n=187-199 [74.8%-91.7%]). Among those without psychological symptoms, nurses constituted a higher proportion than doctors and nonmedical health care workers (n=194 [40.2%], n=142 [29.5%], and n=146 [30.3%], respectively). Nurses in Vietnam showed the highest level of depression, stress, intrusion, avoidance, and hyperarousal symptoms compared to those in Singapore, Malaysia, and Indonesia. Nurses in Singapore had the highest level of anxiety. In addition, nurses had the lowest level of stress, which is the most distinctive psychological outcome characteristic derived from machine learning models, compared to other health care workers. Data for India were excluded from the analysis due to the differing psychological response pattern observed in nurses in India. A large number of female nurses emigrating from South India could not have psychologically coped well without the support from family members while living alone in other states. CONCLUSIONS: Nurses were least psychologically affected compared to doctors and other health care workers. Different contexts, cultures, and points in the pandemic curve may have contributed to differing patterns of psychological outcomes amongst nurses in various Asia-Pacific countries. It is important that all health care workers practice self-care and render peer support to bolster psychological resilience for effective coping. In addition, this study also demonstrated the potential use of decision tree-based machine learning models and SHAP value plots in identifying contributing factors of sophisticated problems in the health care industry.
RESUMO
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has led to significant strain on front-line healthcare workers. AIMS: In this multicentre study, we compared the psychological outcomes during the COVID-19 pandemic in various countries in the Asia-Pacific region and identified factors associated with adverse psychological outcomes. METHOD: From 29 April to 4 June 2020, the study recruited healthcare workers from major healthcare institutions in five countries in the Asia-Pacific region. A self-administrated survey that collected information on prior medical conditions, presence of symptoms, and scores on the Depression Anxiety Stress Scales and the Impact of Events Scale-Revised were used. The prevalence of depression, anxiety, stress and post-traumatic stress disorder (PTSD) relating to COVID-19 was compared, and multivariable logistic regression identified independent factors associated with adverse psychological outcomes within each country. RESULTS: A total of 1146 participants from India, Indonesia, Singapore, Malaysia and Vietnam were studied. Despite having the lowest volume of cases, Vietnam displayed the highest prevalence of PTSD. In contrast, Singapore reported the highest case volume, but had a lower prevalence of depression and anxiety. In the multivariable analysis, we found that non-medically trained personnel, the presence of physical symptoms and presence of prior medical conditions were independent predictors across the participating countries. CONCLUSIONS: This study highlights that the varied prevalence of psychological adversity among healthcare workers is independent of the burden of COVID-19 cases within each country. Early psychological interventions may be beneficial for the vulnerable groups of healthcare workers with presence of physical symptoms, prior medical conditions and those who are not medically trained.
RESUMO
BACKGROUND: Randomized controlled trials provide high-level evidence, but the necessity to include selected patients may limit the generalisability of their results. METHODS: Comparisons were made of baseline and outcome data between patients with acute ischemic stroke (AIS) recruited into the alteplase-dose arm of the international, multi-center, Enhanced Control of Hypertension and Thrombolysis Stroke study (ENCHANTED) in the United Kingdom (UK), and alteplase-treated AIS patients registered in the UK Sentinel Stroke National Audit Programme (SSNAP) registry, over the study period June 2012 to October 2015. RESULTS: There were 770 AIS patients (41.2% female; mean age 72 years) included in ENCHANTED at sites in England and Wales, which was 19.5% of alteplase-treated AIS patients registered in the SSNAP registry. Trial participants were significantly older, had lower baseline neurological severity, less likely Asian, and had more premorbid symptoms, hypertension and atrial fibrillation. Although ENCHANTED participants had higher rates of symptomatic intracerebral hemorrhage than those in SSNAP, there were no differences in onset-to-treatment time, levels of disability (assessed by the modified Rankin scale) at hospital discharge, and mortality over 90 days between groups. CONCLUSIONS: Despite the high level of participation, equipoise over the dose of alteplase among UK clinician investigators favored the inclusion of older, frailer, milder AIS patients in the ENCHANTED trial.

OBJECTIVE: To evaluate a low-cost mixed-method research tool (SegWeigh) that informs awareness raising and family planning interventions for potential contraceptive users. METHODS: A pilot study of SegWeigh was conducted in Uganda and Vietnam between September 3, 2012, and February 21, 2013. User archetypes were produced in four steps by triangulating Demographic and Health Survey (DHS) data; a secondary literature review; family planning service provision data; and primary qualitative investigation. RESULTS: Triangulation of DHS analysis, secondary literature and service data revealed three potential user profiles: Ugandan women wanting to space pregnancies; Ugandan men wanting to limit pregnancies; and unmarried Vietnamese women having infrequent sex. Archetypes were subsequently created of "Kibuuka," a 52-year-old semi-literate subsistence farmer in rural Uganda, and "Anh," a 20-year-old student in Hanoi, Vietnam. CONCLUSION: SegWeigh rapidly produced data-rich "real life" user profiles that might help to tailor family planning interventions.

OBJECTIVE: To explore the perspectives of abortion service users regarding termination methods and abortion service delivery in Vietnam. MATERIALS AND METHODS: Structured exit interviews were conducted between August and November 2011 with women who underwent termination of pregnancy at 62 public health facilities in Hanoi, Khanh Hoa, and Ho Chi Minh City in Vietnam. All women presenting for termination during the study period were recruited to participate in the study. Following their abortion, women were asked about their perspectives on abortion service delivery and attributes of medical abortion (MA) versus manual vacuum aspiration (MVA). Multiple logistic regression was used to assess the association between current method uptake and each attribute. RESULTS: A total of 1,233 women were included in the survey: 541 (43.9%) from Hanoi, 163 (13.2%) from Khanh Hoa, and 529 (42.9%) from Ho Chi Minh: 23.1% underwent MA; 78.9% reported that women should be given a choice between MA and MVA; and 77.6% thought that abortion services were accessible. Among the 48% who responded, 30.1% thought that MA should be made available at primary/secondary health care facilities. Among women who had previously undergone both methods, women who reported that MA "feels more natural" (like a menstrual regulation/period) were more likely to choose MA for their current abortion (odds ratio 2.15, 95% confidence interval 1.26-3.69). CONCLUSION: MA uptake is significantly lower than MVA uptake. Further insights to women's perceptions of MA in Vietnam could help improve abortion service delivery in the country.
RESUMO
OBJECTIVE: To assess public service providers' knowledge of medical abortion (MA) and practices, and perspectives on expanding the use of MA to primary and secondary health facilities in Vietnam. METHODS: A cross-sectional study was conducted via an interviewer-administered questionnaire among abortion providers (n=905) from public health facilities between August 2011 and January 2012. RESULTS: Overall, 31.1% of providers performed both surgical and medical abortions; 68.9% offered only surgical abortion. Providers were knowledgeable about the regimen/dosage of mifepristone plus misoprostol regimen; however, knowledge scores were low for gestational age limits for MA, adverse effects of the combined drug regimen, and safety and effectiveness of MA compared with surgical abortion. Knowledge scores were significantly lower among providers in rural areas than among those in urban settings. A large proportion of providers (82.9%) thought that MA should be expanded to primary and secondary health facilities. Perceived barriers to MA expansion included lack of knowledge and training, qualified staff, adequate drug supplies, equipment, or facilities, guidelines and protocols on MA, and patient awareness. CONCLUSION: Provision of MA in Vietnam was found to be disproportionate to surgical abortion provision and to vary by region. Knowledge of MA was moderate, but poorer among providers in rural settings.

BACKGROUND: The purpose of this study was to investigate attributes of public service providers associated with the provision of medical abortion in Vietnam. METHODS: We conducted a cross-sectional study via interviewer-administered questionnaire among abortion providers from public health facilities in Hanoi, Khanh Hoa, and Ho Chi Minh City in Vietnam between August 2011 and January 2012. We recruited abortion providers at all levels of Vietnam's public health service delivery system. Participants were questioned about their medical abortion provision practices and perspectives regarding abortion methods. RESULTS: A total of 905 providers from 62 health facilities were included, comprising 525 (58.0%) from Hanoi, 122 (13.5%) from Khanh Hoa, and 258 (28.5%) from Ho Chi Minh City. The majority of providers were female (96.7%), aged ≥25 years (94%), married (84.4%), and had at least one child (89%); 68.9% of providers offered only manual vacuum aspiration and 31.1% performed both medical abortion and manual vacuum aspiration. Those performing both methods included physicians (74.5%), midwives (21.7%), and nurses (3.9%). Unadjusted analyses showed that female providers (odds ratio 0.1; 95% confidence interval 0.01-0.30) and providers in rural settings (odds ratio 0.3; 95% confidence interval 0.08-0.79) were less likely to provide medical abortion than their counterparts. Obstetricians and gynecologists were more likely to provide medical abortion than providers with nursing/midwifery training (odds ratio 22.2; 95% confidence interval 3.81-129.41). The most frequently cited advantages of medical abortion for providers were that no surgical skills are required (61.7%) and client satisfaction is better (61.0%). CONCLUSION: Provision of medical abortion in Vietnam is lower than provision of manual vacuum aspiration. While the majority of abortion providers are female midwives in Vietnam, medical abortion provision is concentrated in urban settings among physicians. Individuals providing medical abortion found that the method yields high client satisfaction.
RESUMO
OBJECTIVE: To investigate the attributes of service users associated with uptake of medical abortion (MA) versus manual vacuum aspiration (MVA) at public health facilities in Vietnam. METHODS: Structured exit interviews were conducted among women who underwent termination at 62 public health facilities in Hanoi, Khanh Hoa, and Ho Chi Minh City (HCMC) between August and December 2011. Data on sociodemographic, abortion-related, and service-related factors were compared between women who underwent MVA versus MA. RESULTS: Overall, 1233 women completed the study survey: 541 (43.9%) from Hanoi; 163 (13.2%) from Khanh Hoa; and 529 (42.9%) from HCMC. Almost one-quarter of women (23.1%) had chosen MA. After controlling for sociodemographic factors, women living in Khanh Hoa (odds ratio [OR], 13.4; 95% confidence interval [CI], 5.3-33.8) and HCMC (OR, 5.8; 95% CI, 2.1-15.9) were more likely to have undergone MA than women in Hanoi. Older women were less likely to have undergone MA (P < 0.05), and those who had previously heard of MA were twice as likely to have undergone MA (P = 0.020). CONCLUSION: Uptake of MA was lower than that of MVA and varied by province. Women in Vietnam will make their own judgment about which method to choose if they have prior knowledge of both.

OBJECTIVE: To determine predictors of repeat abortion in 3 provinces in Vietnam. METHODS: In a cross-sectional study between August and December 2011, women who underwent abortion were interviewed after the procedure in 62 public health facilities in Hanoi, Khanh Hoa, and Ho Chi Minh City (HCMC). Information on sociodemographic factors, contraceptive and reproductive history and intentions, and opinions and experience of abortion services was collected. The primary outcome was repeat (≥2) abortions. RESULTS: Overall, 1224 women were interviewed: 534 from Hanoi, 163 from Khanh Hoa, and 527 from HCMC. The mean age and parity of the respondents were 29 years and 1.8, respectively, and 79.6% were married. Approximately half of the respondents were not using contraception before pregnancy. The prevalence of repeat abortion was 31.7%. In multivariate models, significant predictors of repeat abortion included living in Hanoi, higher parity, age 35 years or older, and having 2 or more daughters (versus 1) or no sons (versus 1) after controlling for parity (all P < 0.05). CONCLUSION: Repeat abortion remains high in Vietnam, fueled partly by inadequate contraceptive use. Son preference seems to be an important predictor of repeat abortion. Strengthening post-abortion contraceptive counseling and promoting long-acting contraceptive methods are essential to reduce repeat abortion.

BACKGROUND: Data regarding thrombolysis for acute ischemic stroke in Asia are scarce and only a small percentage of patients are thrombolysed. The dose of intravenous tissue plasminogen activator (IV-tPA) in Asia remains controversial. Case-controlled observation studies in Asia included only Japanese patients and suggested the clinical efficacy and safety of low-dose IV-tPA (0.6 mg/kg body weight; max 60 mg) comparable to standard dose (0.9 mg/kg body weight; max. 90 mg). Reduced treatment cost, lower symptomatic intracerebral hemorrhage risk and comparable efficacy encouraged many Asian centers to adopt low-dose or even variable-dose IV-tPA regimens. We evaluated various Asian thrombolysis studies and compared with SITS-MOST registry and NINDS trial. METHODS: We included the published studies on acute ischemic stroke thrombolysis in Asia. Unadjusted relative risks and 95% Confidence intervals were calculated for each study. Pooled estimates from random effects models were used because the tests for heterogeneity were significant. RESULTS: We found only 18 publications regarding acute ischemic stroke thrombolysis in Asia that included total of 9300 patients. Owing to ethnic differences, stroke severity, small number of cases in individual reports, outcome measures and tPA dose regimes, it is difficult to compare these studies. Functional outcomes were almost similar (to Japanese studies) when lower-dose IV-tPA was used in non-Japanese populations across Asia. Interestingly, with standard dose IV-tPA, considerably better functional outcomes were observed, without increasing symptomatic intracerebral hemorrhage rates. CONCLUSIONS: Variable dose regimens of IV-tPA are used across Asia without any reliable or established evidence. Establishing a uniform IV-tPA regimen is essential since the rapid improvements in health-care facilities and public awareness are expected to increase the rates of thrombolysis in Asia.
