Antimicrobial resistance (AMR) is a global public health threat that warrants urgent attention. Countries developed their national action plans (NAPs) following the launch of the Global Action Plan on AMR in 2015. The development and implementation of NAPs are often complicated due to the multifaceted nature of AMR, and studies analyzing these aspects are lacking. We analyzed the development and implementation of the Philippine NAP on AMR with guidance from an AMR governance framework. We conducted in-depth interviews with 37 participants across the One Health spectrum. The interviews were transcribed verbatim and were analyzed thematically, adopting an interpretative approach. The enabling factors for NAP implementation include (1) a high level of governmental support and involvement of relevant stakeholders, (2) the development of policies to support improved responses in infection prevention and control and antimicrobial stewardship, and (3) better engagement and advocacy by professional associations and civil society groups. The challenges include (1) a lack of resources and regulatory capacity, (2) insufficient impetus for AMR research and surveillance, and (3) limited One Health engagement. Although there has been considerable progress for human health, strengthening the involvement and representation of the animal health and environment sectors in the AMR scene must be undertaken. Developing well-defined roles within policies will be paramount to the strong implementation of AMR strategies.

Antimicrobial resistance (AMR) is a global public health threat that affects humans, animals, and the environment across the One Health spectrum. Singapore launched its own National Strategic Action Plan (NSAP) on AMR in 2017 with the aim of tackling the growing threat of AMR in Singapore through coordinated approaches. However, little is known about the implementation of the NSAP. In this study, we analysed the implementation of the NSAP with guidance from an AMR governance framework. We conducted in-depth interviews with 20 participants across the One Health spectrum. The interviews were transcribed verbatim and analysed thematically. Overall, the implementation of activities against AMR was more advanced with respect to human health compared to other sectors such as (1) AMR and antimicrobial use (AMU) surveillance systems in hospitals; (2) the hospital antimicrobial stewardship (AMS) service and legislation to optimise AMU; (3) the national children and adults vaccination programme for IPC; (4) multiple avenues for education and awareness for both professionals and public; and (5) extensive research and collaboration networks with many sources of funding. Areas that were lacking presented problems including (1) an incomplete surveillance system for AMR and AMU across all sectors; (2) the need for better AMS and legislation in some sectors; (3) insufficient innovation in education for sustained behavioural modification; and (4) the need for more open research collaborations and the translation of research into policy outcomes. Improvements in these areas will enhance the overall implementation of the NSAP through a more holistic One Health approach.

Tuberculosis (TB) is a chronic infectious disease that remains to be a primary health concern globally. The Philippines is among the top TB-burdened countries. Workplace TB prevention and control programs are essential to ensure the health and safety of workers and economic security. There remains a knowledge gap regarding the Philippine workplace TB prevention and control program implementation. This qualitative study involving key informant interviews reviewed the implementation of the workplace TB program in selected companies in a high TB burden region in Eastern Philippines. Results were presented under four themes in accordance with the components of the workplace TB policy: preventive strategies, medical management, data recording and reporting, and social policy. Various good practices, opportunities, and challenges in the implementation of the workplace TB program were identified. There is a need to strengthen the enforcement of policy across different components. Compliance with guidelines on preventive strategies and recording and reporting schemes needs to be intensified. Coordination across different levels and agencies may also be enhanced to allow more efficient implementation. Increased awareness of corporate decision-makers may improve company ownership of the program leading to improved implementation while increased awareness of employees on their rights and entitlements may likewise enhance compliance.

Background and Objective. The World Health Organization (WHO) reported that most of the tuberculosis (TB) cases are aged between 15 to 54 years old, the working population. This study described workplace policies on TB in selected low- and middle-income countries (LMIC) in Asia-Pacific. Methods. Among the LMICs, countries wherein TB is a public health concern were included. Six policies written in English were included in this study and were reviewed based on the components of the TB workplace programs that were extracted from the WHO Guidelines for Workplace TB Control Activities. Results. The Philippine policy had the most number of components while those of Cambodia and Papua New Guinea had the least. Only the component on implementing environmental controls was common among the policies. Components on respecting patient rights and confidentiality, tailoring of workload to TB patient’s state of health, registration of all patients with TB diagnosis, reporting of cases to central NTP office, recording of standard treatment outcome, and inclusion of multidrug-resistant TB (MDR-TB) provisions were missing for the majority of the policy documents. Conclusion. The workplace TB program policies included in this study can be reviewed and updated accordingly, with the coverage expanding to all workplaces. The policies can also integrate measures on COVID-19 as the pandemic has slowed the progress in TB control. With the similarities in the preventive measures against TB and COVID-19, this can be an avenue to develop integrated policies especially for workplaces.

Introduction: Like many countries globally, childhood immunisation coverage is below government targets in the Philippines and has worsened during the COVID-19 pandemic, leading to outbreaks of vaccine-preventable diseases. This study aimed to identify the social and behavioural drivers of routine childhood immunisation and preferred caregiver information sources to improve uptake in the Philippines. Methods: A quantitative, cross-sectional study, as part of a larger mixed-methods study, was undertaken in three regions in the Philippines with low immunisation coverage in 2023. Data on Behavioural and Social Drivers (BeSD) of immunisation, preferred information sources and vaccination status of children under 5 years were collected, analysed and reported according to the WHO BeSD framework. Results: The study included 653 caregivers and 950 children, with 65% of children fully immunised, 31.8% partially immunised and 2.5% being zero-dose or having received no vaccines. Key reasons for complete vaccination included the protection vaccines offer, healthcare worker recommendations and vaccines being free of charge. For partial vaccination, top reasons were intercurrent illness, inaccessible vaccination sites and parental belief that the child was too young to receive vaccines. The most common reason for non-vaccination was also intercurrent illness. The predictors of complete vaccination were older age of caregivers (46–59 years) (prevalence ratio (PR)=1.29; 95% CI 1.12 to 1.48) and low concerns about vaccine safety (PR=1.13; 95% CI 1.03 to 1.25). Other Christian denominations, compared with Catholics, were less likely to have fully immunised children (PR 0.82; 95% CI 0.69 to 0.97). Preferred vaccine information sources included the Department of Health, healthcare workers and mass media. Conclusions: We found that only 65% of children were fully immunised in 2023, with both access and acceptance factors impacting uptake of routine childhood vaccines. Improving service accessibility and education of healthcare workers on vaccine safety and effectiveness and more targeted messaging from health authorities and mass media about the benefits of vaccination could increase uptake in the Philippines, with learnings from this study applicable globally.

Background: The COVID-19 pandemic prompted extensive vaccination efforts globally, yet in the Philippines, many families remained unvaccinated. Caregivers are key decision-makers for family vaccination, but evidence on factors influencing their own vaccine uptake is limited. Methods: A cross-sectional survey of primary caregivers was conducted in low COVID-19 vaccine uptake regions in the Philippines from July to October 2023 using a validated questionnaire. Multivariable logistic regression identified enablers and barriers to vaccine uptake. Results: Among 775 respondents, 72.3% completed primary vaccination, 3.3% had incomplete vaccination, and 24.4% were unvaccinated. Key factors for vaccination included self, family, and community protection, and the influence of government regulations. Distrust in vaccine safety was the main barrier. Positive associations with vaccine uptake were found for age [30–45 years (aOR = 2.23) and 46–59 years (aOR = 2.84)], education [secondary (aOR = 2.25) and tertiary (aOR = 4.93)], and employment (aOR = 1.99). Confidence in vaccine safety (aOR = 1.92), vaccine effectiveness (aOR = 2.23), and satisfaction with vaccination efforts (aOR = 2.39) were additional enablers. Disagreement with restrictions on the unvaccinated was a barrier (aOR = 0.31). Conclusions: This study identified multiple factors influencing COVID-19 vaccination among primary caregivers in low uptake areas of the Philippines. Interventions addressing perceptions about vaccine safety and effectiveness, particularly among younger and less educated caregivers, may improve public trust and satisfaction with vaccination efforts.
