The impact of rotavirus vaccination in the prevalence of gastroenteritis and comorbidities among children after suboptimal rotavirus vaccines implementation in Taiwan: A population-based study.

ABSTRACT: In Taiwan, rotavirus vaccination was implemented in 2006 in the private sector. The population-based impact of rotavirus vaccination on gastroenteritis and comorbidities of children remains under-investigated.We analyzed the annual prevalence of rotavirus-related disease, including gastroenteritis, convulsions, epilepsy, type I diabetes mellitus, intussusception, and biliary atresia among children under 5 years of age. Data were collected from Taiwan's National Health Insurance Research Database, a nationwide population-based database. A 16-year retrospective cohort study was conducted between 2000 and 2015.Among children <5 years of age, the prevalence of gastroenteritis decreased after 2012 (44,259.69 per 100 thousands) and remained lower through 2015 (39,931.11per 100 thousands, P < .001). The prevalence of convulsions rose steadily and significantly from 2007 (775.90 per 100 thousands) to 2015 (962.17 per 100 thousands, P < .001). The prevalence of epilepsy decreased significantly until reaching a nadir in 2013 (from 501.56 to 293.53 per 100 thousands, P < .001). The prevalence of biliary atresia tended upward, and surged suddenly in 2007 with a peak in 2013 (18.74 per 100 thousands). Among infants (<1 year of age) from 2000 to 2015, the prevalence of gastroenteritis declined steadily, and more rapidly after 2007 (22,513 to 17,285 per 100 thousands).In Taiwan, after introducing rotavirus vaccination, gastroenteritis in young children decreased, especially in infancy. However, gastroenteritis is still common in children, given other emerging pathogens. Our results highlight the impact of rotavirus vaccines on children's health in Taiwan and provide indications for future preventive medicine and healthcare strategies in children.

The National Health Plan 2030: Its Purpose and Directions of Development.

The National Health Plan 2030 (HP2030) started to be prepared in 2017 and was completed and announced in December 2020. This study presents an overview of how it was established, the major changes in policies, its purpose, and future directions. This study analyzed the steps taken in the past 4 years to establish HP2030 and reviewed major issues at the international and governmental levels based on an evaluation of HP2020 and its content. HP2030 establishes 6 divisions and 28 topic areas, and it will continue to expand investments in health with a total budget of 2.5 trillion Korean won. It also established goals to enhance health equity for the first time, with the goal of calculating healthy life expectancy in a way that reflects the circumstances of Korea and reducing the gap in income and healthy life expectancy between regions. The establishment of HP2030 is significant in that it constitutes a sustainable long-term plan with sufficient preparation, contains policy measures that everyone participates in and makes together, and works towards improvements in universal health standards and health equity. With the announcement of HP2030, which includes goals and directions of the national health policy for the next 10 years, it will be necessary to further strengthen collaboration with relevant ministries, local governments, and agencies in various fields to concretize support for prevention-centered health management as a national task and to develop a health-friendly environment that considers health in all policy areas.

Tracking Progress from Policy Development to Implementation: A Case Study on Adoption of Mandatory Regulation for Nutrition Labelling in Malaysia.

Mandatory nutrition labelling, introduced in Malaysia in 2003, received a "medium implementation" rating from public health experts when previously benchmarked against international best practices by our group. The rating prompted this qualitative case study to explore barriers and facilitators during the policy process. Methods incorporated semi-structured interviews supplemented with cited documents and historical mapping of local and international directions up to 2017. Case participants held senior positions in the Federal government (n = 6), food industry (n = 3) and civil society representations (n = 3). Historical mapping revealed that international directions stimulated policy processes in Malaysia but policy inertia caused implementation gaps. Barriers hindering policy processes included lack of resources, governance complexity, lack of monitoring, technical challenges, policy characteristics linked to costing, lack of sustained efforts in policy advocacy, implementer characteristics and/or industry resistance, including corporate political activities (e.g., lobbying, policy substitution). Facilitators to the policy processes were resource maximization, leadership, stakeholder partnerships or support, policy windows and industry engagement or support. Progressing policy implementation required stronger leadership, resources, inter-ministerial coordination, advocacy partnerships and an accountability monitoring system. This study provides insights for national and global policy entrepreneurs when formulating strategies towards fostering healthy food environments.

Adapting inpatient addiction medicine consult services during the COVID-19 pandemic.

BACKGROUND: We describe addiction consult services (ACS) adaptations implemented during the Novel Coronavirus Disease 2019 (COVID-19) pandemic across four different North American sites: St. Paul's Hospital in Vancouver, British Columbia; Oregon Health & Sciences University in Portland, Oregon; Boston Medical Center in Boston, Massachusetts; and Yale New Haven Hospital in New Haven, Connecticut. EXPERIENCES: ACS made system, treatment, harm reduction, and discharge planning adaptations. System changes included patient visits shifting to primarily telephone-based consultations and ACS leading regional COVID-19 emergency response efforts such as substance use treatment care coordination for people experiencing homelessness in COVID-19 isolation units and regional substance use treatment initiatives. Treatment adaptations included providing longer buprenorphine bridge prescriptions at discharge with telemedicine follow-up appointments and completing benzodiazepine tapers or benzodiazepine alternatives for people with alcohol use disorder who could safely detoxify in outpatient settings. We believe that regulatory changes to buprenorphine, and in Vancouver other medications for opioid use disorder, helped increase engagement for hospitalized patients, as many of the barriers preventing them from accessing care on an ongoing basis were reduced. COVID-19 specific harm reductions recommendations were adopted and disseminated to inpatients. Discharge planning changes included peer mentors and social workers increasing hospital in-reach and discharge outreach for high-risk patients, in some cases providing prepaid cell phones for patients without phones. RECOMMENDATIONS FOR THE FUTURE: We believe that ACS were essential to hospitals' readiness to support patients that have been systematically marginilized during the pandemic. We suggest that hospitals invest in telehealth infrastructure within the hospital, and consider cellphone donations for people without cellphones, to help maintain access to care for vulnerable patients. In addition, we recommend hospital systems evaluate the impact of such interventions. As the economic strain on the healthcare system from COVID-19 threatens the very existence of ACS, overdose deaths continue rising across North America, highlighting the essential nature of these services. We believe it is imperative that health care systems continue investing in hospital-based ACS during public health crises.

Social Determinants of Health and Implementation Research: Lessons from the COVID-19 Pandemic.

During the past three decades, the world has experienced many clinical and public health challenges that require implementation of practices and policies informed by an understanding of social determinants of health and health inequities, but perhaps none as global and pervasive as the current COVID-19 pandemic. In the context of this special themed issue on Social Determinants of Health and Implementation Research: Three Decades of Progress and a Need for Convergence, we highlight the application of social determinants of health and implementation research on various aspects of the COVID-19 pandemic.

Caring for critically ill adults in paediatric intensive care units in England during the COVID-19 pandemic: planning, implementation and lessons for the future.

OBJECTIVE: To describe the experience of paediatric intensive care units (PICUs) in England that repurposed their units, equipment and staff to care for critically ill adults during the first wave of the COVID-19 pandemic. DESIGN: Descriptive study. SETTING: Seven PICUs in England. MAIN OUTCOME MEASURES: (1) Modelling using historical Paediatric Intensive Care Audit Network data; (2) space, staff, equipment, clinical care, communication and governance considerations during repurposing of PICUs; (3) characteristics, interventions and outcomes of adults cared for in repurposed PICUs. RESULTS: Seven English PICUs, accounting for 137 beds, repurposed their space, staff and equipment to admit critically ill adults. Neighbouring PICUs increased their bed capacity to maintain overall bed numbers for children, which was informed by historical data modelling (median 280-307 PICU beds were required in England from March to June). A total of 145 adult patients (median age 50-62 years) were cared for in repurposed PICUs (1553 bed-days). The vast majority of patients had COVID-19 (109/145, 75%); the majority required invasive ventilation (91/109, 85%). Nearly, a third of patients (42/145, 29%) underwent a tracheostomy. Renal replacement therapy was provided in 20/145 (14%) patients. Twenty adults died in PICU (14%). CONCLUSION: In a rapid and unprecedented effort during the first wave of the COVID-19 pandemic, seven PICUs in England were repurposed to care for adult patients. The success of this effort was underpinned by extensive local preparation, close collaboration with adult intensivists and careful national planning to safeguard paediatric critical care capacity.

Staff Perceptions and Implementation Fidelity of an Autism Spectrum Disorder Care Pathway on a Child/Adolescent General Psychiatric Inpatient Service.

While youth with autism spectrum disorder (ASD) are psychiatrically hospitalized at high rates, general psychiatric settings are not designed to meet their unique needs. Previous evaluations of an ASD-Care Pathway (ASD-CP) on a general psychiatric unit revealed sustained reductions in crisis interventions (intramuscular medication use, holds/restraints; Cervantes et al. in J Autism Dev Disord 49(8):3173-3180, https://doi.org/10.1007/s10803-019-04029-6 , 2019; Kuriakose et al. in J Autism Dev Disord 48(12):4082-4089, https://doi.org/10.1007/s10803-018-3666-y , 2018). The current study investigated staff perceptions of the ASD-CP (N = 30), and examined rates of ASD-CP implementation fidelity in relation to patient outcomes (N = 28). Staff identified visual communication aids and reward strategies as most helpful. The number of days of reward identification early in the inpatient stay was associated with fewer crisis interventions later in a patient's stay.

Artificial Intelligence in Ophthalmology: Evolutions in Asia.

Artificial intelligence (AI) has been studied in ophthalmology since availability of digital information in ophthalmic care. The significant turning point was availability of commercial digital color fundus photography in the late 1990s, which caused digital screening for diabetic retinopathy (DR) to take off. Automated Retinal Disease Assessment software was then developed using machine learning to detect abnormal lesions in fundus to screen DR. The use of this version of AI had not been generalized because the specificity at 45% was not high enough, although the sensitivity reached 90%. The recent breakthrough in machine learning is the invent of deep learning, which accelerates its performance to be on par with experts. The first 2 breakthrough studies on deep learning for screening DR were conducted in Asia. The first represented collaboration of datasets between Asia and the United States for algorithms development, whereas the second represented algorithms developed in Asia but validated in different populations across the world. Both found accuracy for detecting referable DR of >95%. Diversity and variety are unique strengths of Asia for AI studies. There are many more studies of AI ongoing in Asia not only as prospective deployments in DR but in glaucoma, age-related macular degeneration, cataract, and systemic disease, such as Alzheimer's disease. Some Asian countries have laid out plans for digital health care system using AI as one of the puzzle pieces for solving blindness. More studies on AI and digital health are expected to come from Asia in this new decade.

The only way is up: priorities for implementing long-acting antiretrovirals for HIV prevention and treatment.

PURPOSE OF REVIEW: Long-acting HIV treatment and prevention (LAHTP) can address some of the achievement gaps of daily oral therapy to bring us closer to achieving Joint United Nations Programme on HIV/AIDS Fast-track goals. Implementing these new technologies presents individual-level, population-level, and health systems-level opportunities and challenges. RECENT FINDINGS: To optimize LAHTP implementation and impact, decision-makers should define and gather relevant data to inform their investment case within the existing health systems context. Programmatic observations from scale-up of antiretroviral therapy, oral preexposure prophylaxis, voluntary medical male circumcision, and family planning offer lessons as planning begins for implementation of LAHTP. Additional data intelligence should be derived from formative studies, pragmatic clinical trials, epidemiologic and economic modeling of LAHTP. Key implementation issues that need to be addressed include optimal communication strategies for demand creation; target setting; logistics and supply chain of commodities needed for LAHTP delivery; human resource planning; defining and operationalizing monitoring and evaluating metrics; integration into health systems. SUMMARY: Successful LAHTP implementation can bolster treatment and prevention coverage levels if implementation issues outlined above are proactively addressed in parallel with research and development so that health systems can more rapidly integrate new technologies as they gain regulatory approval.

Primary HPV-based cervical cancer screening in Europe: implementation status, challenges, and future plans.

BACKGROUND: Cytology-based screening has been a cornerstone of cervical cancer prevention for decades. Following extensive evidence demonstrating higher sensitivity and accuracy, lower variability and better reproducibility of human papillomavirus (HPV)-based screening compared with conventional or liquid-based cytology, recent European guidelines strongly recommend primary HPV-based screening over standard cytology-based screening. In addition, HPV-based screening offers the possibility of self-sampling and makes possible longer screening intervals in women with negative screening results. OBJECTIVES: We summarize the current status of implementation of HPV-based screening in Europe, describe the real-life experience and challenges from countries already performing HPV-based screening, and briefly review immediate and long-term plans for screening implementation in selected European countries. SOURCES: Data were obtained from peer-reviewed literature, personal communication with experts and authorities involved in formulating national recommendations and practical guidelines, and relevant national websites. CONTENT: As of July 2019, the Netherlands and Turkey are the only European countries with fully implemented national HPV-based cervical cancer screening. Italy, Sweden and Finland have already implemented HPV-based screening in several regions, and several other countries are at various stages of implementation. Some countries are considering transitioning from cytology-based to HPV-based screening, but are struggling with the suboptimal performance of current population-based programmes. Implementation of HPV-based screening has resulted in higher colposcopy referral rates, but also higher detection rates of CIN3+ lesions and cervical cancers requiring immediate treatment. Cytology is mostly used as a triage test, although other strategies are under consideration in some countries. IMPLICATIONS: HPV-based screening is best suited in organized population-based screening settings. In 2019, cervical cancer screening policies across Europe vary greatly. Experience in countries with national and regional HPV-based screening already implemented is generally very positive. Urgent action is needed in many European countries, especially those with suboptimal opportunistic cytology-based cervical cancer screening.

En este trabajo se describe el inicio del proceso de implementación de la evaluación del impacto en salud en la Comunitat Valenciana como un instrumento para incorporar el marco de los determinantes sociales y las desigualdades en salud en las políticas emanadas de los diferentes departamentos del gobierno valenciano. La propuesta implica: 1) el compromiso político, con acciones legislativas y en la planificación estratégica; 2) la creación de estructuras facilitadoras del trabajo intersectorial, con la constitución de la comisión de evaluación del impacto en salud y del comité técnico intersectorial; y 3) el diseño y la validación de una herramienta para la evaluación simplificada del impacto en salud de las políticas sectoriales adaptada a la Comunitat Valenciana. Se pone en valor la metodología participativa utilizada en todo el proceso y el potencial que representa la evaluación del impacto en salud para el desarrollo de políticas públicas orientadas hacia la ganancia en salud y la equidad

This paper describes the beginning of the implementation process of the health impact assessment in the Valencian Community (Spain), as an instrument to incorporate the framework of social determinants and health inequalities in the policies issued by the different departments of the Valencian government. The proposal involves: 1) political commitment, with legislative and strategic planning actions; 2) the creation of structures to allow intersectoral collaboration, with the establishment of the health impact assessment commission and the intersectoral technical committee; and 3) the design and validation of a tool for the simplified health impact assessment of non-health policies adapted to the Valencian Community. We highlight the importance of the participatory methodology used in the whole process and the potential of the health impact assessment for the development of public policies oriented to improve health and equity

Bringing HIV Self-Testing to Scale in the United States: a Review of Challenges, Potential Solutions, and Future Opportunities.

HIV self-testing (HIVST) provides an at-home option to counter the barriers that patients face with testing performed in health care settings. HIVST has gradually increased in popularity in a time when social media and technology-based solutions are preferred. In this paper, we consider the aspects of self-testing that merit its integration into HIV testing and prevention systems in the United States. Several elements favor self-testing for large-scale implementation, including ease of use, convenience, potential for integration with mobile health (mHealth), and availability for various modes of distribution. HIVST has a demonstrated ability to reach at-risk individuals who otherwise rarely test. The paradigm of self-testing, however, introduces new challenges, including lesser test performance relative to that in health care settings, nonstandard counseling following receipt of test results, and difficulty in providing linkage to care. After discussing the performance of oral fluid versus blood-based HIVST, we review data regarding acceptability of HIVST, offer insights into counseling and linkage to care for HIVST, and provide examples of novel applications of and future research directions for HIVST.
