METHODS: A cross-sectional health-related quality of life survey involving TDT patients from 12 different treatment centers across Malaysia was conducted using the Malay PedsQL 4.0 Generic Core Scales and the Malay EQ-5D-3L questionnaire. Patients with non-TDT and other hemoglobinopathies were excluded. Convergent, discriminant, and known-group validity of the EQ-5D-3L was assessed against the PedsQL 4.0 Generic Core Scales in children. In the adult population, known-group validity of the EQ-5D-3L was assessed using an a priori hypothesis between patients' demographic characteristics and health outcomes obtained from literature.
RESULTS: A total of 370 children and 225 adults were sampled. The mean (standard deviation) EQ-5D-3L scores of the children were 0.892 (0.082) and the adults were 0.887 (0.085). Convergent and discriminant validity was identified when correlated with the PedsQL domain in children. In both groups, known-group validity was evident when comparing groups of patients with reported problems to the group of patients with no reported problems on the EQ-5D-3L domains based on the a priori hypothesis derived from literature.
CONCLUSION: This study found convergent, discriminant, and known-group validity of the Malay EQ-5D-3L in a population-based sample of patients with TDT. Hence, the instrument is valid for the assessment of health-related quality of life in children and adults with TDT in Malaysia.
METHODS: A simulation-based approach contingent on all single-level transitions defined by the EQ-5D-5L descriptive system was used to estimate the MID for each algorithm.
RESULTS: The resulting mean (and standard deviation) instrument-defined MID estimates were Germany, 0.083 (0.022); Indonesia, 0.093 (0.012); Ireland, 0.098 (0.023); Malaysia, 0.072 (0.010); Poland, 0.080 (0.030); Portugal, 0.080 (0.018); Taiwan, 0.101 (0.010); and the United States, 0.078 (0.014).
CONCLUSIONS: These population preference-based MID estimates and accompanying evidence of how such values vary as a function of baseline index score can be used to aid interpretation of index score change. The marked consistency in the relationship between the calculated MID estimate and the range of the EQ-5D-5L index score, represented by a ratio of 1:20, might substantiate a rule of thumb allowing for MID approximation in EQ-5D-5L index score warranting further investigation.
OBJECTIVES: To determine a CE threshold for health care interventions in Malaysia.
METHODS: A cross-sectional, contingent valuation study was conducted using a stratified multistage cluster random sampling technique in four states in Malaysia. One thousand thirteen respondents were interviewed in person for their socioeconomic background, quality of life, and WTP for a hypothetical scenario.
RESULTS: The CE thresholds established using the nonparametric Turnbull method ranged from MYR12,810 to MYR22,840 (~US $4,000-US $7,000), whereas those estimated with the parametric interval regression model were between MYR19,929 and MYR28,470 (~US $6,200-US $8,900). Key factors that affected the CE thresholds were education level, estimated monthly household income, and the description of health state scenarios.
CONCLUSIONS: These findings suggest that there is no single WTP value for a quality-adjusted life-year. The CE threshold estimated for Malaysia was found to be lower than the threshold value recommended by the World Health Organization.
METHODS: A discrete choice experiment was developed to include 7 attributes valued in cancer management: physical, psychological and social functioning, pain control, survival, place of death, and cost. Patients were recruited via convenience sampling from 2 Malaysian public hospitals. The survey questionnaire was administered to patients within 6 months of their cancer diagnosis with a follow-up 3 months later. Conditional logit regression was used to estimate the preference weight, relative attribute importance, and willingness to pay.
RESULTS: One hundred valid responses were collected at baseline and 45 at follow-up. Respondents placed higher values on QoL improvements from severe to moderate or mild levels and to achieve home death over survival extension from 6 to 18 months. However, additional improvements (from moderate to mild) in some of the QoL outcomes were not valued as highly as life extension from 12 to 18 months, showing that it was vital for patients to avoid being in "severe" health dysfunction. Improving physical dysfunction from severe to mild yielded 3 times as much value as additional 1-year survival. After 3 months, the respondents' preferences changed significantly, with increased relative attribute importance of physical functioning, pain control, and cost.
CONCLUSIONS: As QoL outcomes are valued more than survival, palliative care should be introduced as early as possible to alleviate suffering related to advanced cancer.
METHODS: From May to July 2019, a cross-sectional study was conducted among registered general practitioners (GPs) in Indonesia. A contingent valuation method was employed to evaluate the WTP. Besides acceptance and WTP, various explanatory variables were also collected and assessed. A logistic regression and a multivariable linear regression were used to explore the explanatory variables influencing acceptance and WTP, respectively.
RESULTS: Among 407 respondents, 391 (96.0%) expressed acceptance of a free vaccination. The mean and median WTP was US$ 37.0(95%CI:US$ 32.76-US$ 41.23) and US$ 17.90(95%CI:US$ 17.90-US$ 17.90), respectively. In an unadjusted analysis, those 30 years old or younger had 2.94 times greater odds of vaccine acceptance compared to those who were older (95%CI: 1.07-8.08). Location of alma mater, type of workplace, length of individual medical experience, and monthly income of GPs were all significantly associated with WTP.
CONCLUSION: Although the vast majority of GPs would accept a freely provided vaccine, they were also somewhat price sensitive. This finding indicates that partial subsidy maybe required to achieve high vaccine coverage, particularly among GPs at community health centres or those with a shorter duration of medical practice.
OBJECTIVES: To assess the test-retest reliability of the Parent Attitudes about Childhood Vaccines (PACV) questionnaire in Malay language; to determine the prevalence of vaccine hesitancy among parents and its associations with parents' socio-demographic characteristics.
METHODS: Forward and backward translation of PACV in Malay language was carried out. The reliability of the Malay-PACV questionnaire was tested among parents with children. The same questionnaire was used to study vaccine hesitancy among parents in a tertiary hospital in Kuala Lumpur. Information pertaining to socio-demographic characteristics, sources of information regarding vaccination and vaccine hesitancy were collected. Associations between vaccine hesitancy with socio-demographic factors were tested using Multivariable Logistic Regression.
RESULTS: The Spearman correlation coefficient and Cronbach alpha for total PACV was 0.79 (p<0.001) and 0.79 respectively. The intra-class correlation coefficients of the subscales ranged from 0.54 to 0.90 demonstrating fair to excellent reliability. A total of 63 (11.6%) parents were noted to be vaccine hesitant. In the univariate analyses, vaccine hesitancy was associated with unemployed parents, parents who were younger, had fewer children and non-Muslim. In the multivariate model, pregnant mothers expecting their first child were four times more likely to be vaccine hesitant compared to those who already had one or more children (aOR: 3.91, 95% CI: 1.74-8.79) and unemployed parents were also more likely to be vaccine hesitant (aOR: 1.97, 95% CI: 1.08-3.59). The internet (65.6%) was the main source of information on vaccination followed by brochures (56.9%).
CONCLUSION: The Malay-PACV questionnaire is reliable to be used. The prevalence of vaccine hesitancy among the multi-ethnic Malaysians was comparable with other populations. Pregnant mothers expecting their first child and unemployed parents were found to be more vaccine hesitant.
METHODS: A survey was distributed to national experts in infectious diseases and health-care authorities (March 2015-April 2016), collecting information on local recommendations, costs and perception of barriers for implementation.
RESULTS: Forty-nine of the 79 contacted countries (62% response rate) provided a complete analyzable data. RVI was recommended in 27/49 countries (55%). Although five countries have recommended RVI since 2006, a large number (16, 33%) included RVI in a National Immunization Schedule between 2012 and 2014. The costs of vaccination are covered by the government (39%), by the GAVI Alliance (10%) or public and private insurance (8%) in some countries. However, in most cases, immunization is paid by families (43%). Elevated cost of vaccine (49%) is the main barrier for implementation of RVI. High costs of vaccination (rs=-0.39, p=0.02) and coverage of expenses by families (rs=0.5, p=0.002) significantly correlate with a lower immunization rate. Limited perception of RV illness severity by the families (47%), public-health authorities (37%) or physicians (24%) and the timing of administration (16%) are further major barriers to large- scale RVI programs.
CONCLUSIONS: After 10years since its introduction, the implementation of RVI is still unacceptably low and should remain a major target for global public health. Barriers to implementation vary according to setting. Nevertheless, public health authorities should promote education for caregivers and health-care providers and interact with local health authorities in order to implement RVI.
METHODS: An online survey was sent to mothers aged 27-45 years of primary school pupils in the Fujian province, China. Participants completed questions about HPV related knowledge and health beliefs, intention to take the HPV vaccine and the willingness to pay for bivalent vaccine (2vHPV), quadrivalent vaccine (4vHPV), and 9-valent HPV vaccine (9vHPV).
RESULTS: Of a total of 2339 complete responses, 58.3% reported intent to obtain HPV vaccine. Mothers who were younger in age, residing in urban, working in managerial or professional occupations, who knew someone with cervical cancer and who were able to make independent decisions about the HPV vaccine (vs. joint decision with spouse) were more likely to express intent to have HPV vaccination. Perceived barriers, cues to action and self-efficacy were three of the constructs in the health belief model that significantly influenced HPV vaccination intent. A higher proportion of participants expressed willingness to pay for 2vHPV (81.2%) and 4vHPV (75.9%), as compared to 9vHPV (67.7%).
CONCLUSION: Adults women expressed moderate intention to receive the HPV vaccine. Intervention to address barriers to uptake of the HPV vaccine among adult women in China is warranted.
METHODS: We conducted a health facility-based cross-sectional study in Aceh and West Sumatra province from 1 February to 13 June 2018. Patients who visited outpatient departments, have had children or were expecting their first child, were approached and interviewed to collect information on acceptance, WTP, demographic and socio-economic variables and attitudes towards childhood vaccines. Associations of explanatory variables influencing acceptance and WTP were assessed using logistic regression and linear regression analysis, respectively.
RESULTS: In total, 956 respondents were included in the final analysis of acceptance, of whom 338 (35.3%) expressed their WTP. We found that 757 (79.1%) of the respondents were likely to be vaccinated and to recommend their partner to be vaccinated. Higher educational attainment, having a job, having heard about Zika and a good attitude towards childhood vaccination were associated with ZV acceptance in the univariate analyses. In the multivariate analysis, attitude towards childhood vaccination was the strongest predictor for ZV vaccination. We found the geometric mean and median of WTP was US$ 13.1 (95% CI: 11.37-15.09) and US$ 7.0 (95% CI: 4.47-10.98), respectively. In the final model, having heard about Zika, having a job, and higher income were associated with a higher WTP.
CONCLUSION: Although the acceptance rate of the ZV is relatively high in Indonesia, less than 40% of respondents are willing to pay, underscoring the need for a low-cost, high-quality vaccine and public sector subsidies for Zika vaccinations in the country.
METHODS: We conducted a household survey in Nahuche, Zamfara State in northern Nigeria. Nearly two hundred parents with children under age five were asked about their views on 16 factors using a BWS technique. These factors focused on known attributes that influence the demand for childhood immunization, which were identified from a literature review and reviewed by a local advisory board. The survey systematically presented parents with subsets of six factors and asked them to choose which they think are the most and least important in decisions to vaccinate children. We used a sequential best-worst analysis with conditional logistic regression to rank factors.
RESULTS: The perception that vaccinating a child makes one a good parent was the most important motivation for parents in northern Nigeria to vaccinate children. Statements related to trust and social norms were ranked higher in importance compared to those that highlighted perceived benefits and risks, healthcare service, vaccine information, or opportunity costs. Fathers ranked trust in the media and views of their leaders to be of greatest importance, whereas mothers placed greater importance on social perceptions and norms. Parents of children without routine immunization ranked their trust in local leaders about vaccines higher in considerations, and the media's views lower, compared to parents with children who received routine immunization.
CONCLUSIONS: Framing immunization messages in the context of good parenting and hearing these messages from trusted information sources may motivate parental uptake of childhood vaccines. These results are useful to policymakers to prioritize resources in order to increase awareness and demand for childhood immunization.
MATERIALS AND METHODS: This was a pilot prospective, randomized trial of women aged ≥18 years with SUI symptoms who underwent PFMEs at University Malaya Medical Centre from October 2011 to October 2013. The patients were randomly divided into two groups: control (PFMEs alone) and VKD (PFMEs with VKD biofeedback). The patients underwent 16 weeks of pelvic floor training, during which they were assessed using Australian pelvic floor questionnaires and modified Oxford scales for pelvic floor muscle strength at week 0, 4, and 16.
RESULTS: Forty patients were recruited (control 19, VKD 21). Three patients in the control group dropped out during week 16 training, whereas the VKD group had no dropouts. The VKD group reported significantly earlier improvement in SUI scores, as assessed by the Australian pelvic floor questionnaires (P = .035) at week 4. However, there was no significant difference between the groups' SUI scores at week 16. Pelvic floor muscle strength was significantly better in the VKD group at week 4 (P = .025) and week 16 (P = 0.001). The subjective cure rate was similar in both groups at week 16 (62.5% for control and 61.9% for VKD) (P = 0.742).
CONCLUSION: Using the VKD resulted in significant early improvement in SUI scores, and pelvic muscle strength had improved significantly by the end of the study. The VKD proved useful as an adjunct for pelvic floor training.
