Innovation and technology for global public health

Avaliação do desenvolvimento tecnológico em saúde a partir da ocorrência das epidemias de zika e chikungunya no Brasil

Buscando compreender como as epidemias de zika e chikungunya incitaram o desenvolvimento tecnológico, este estudo realizou levantamento de dados epidemiológicos e prospecção tecnológica, utilizando dados do Instituto Nacional da Propriedade Industrial (INPI) e do Orbit Intelligence. Ainda, analisou produtos desenvolvidos e em desenvolvimento a nível mundial e aqueles registrados no Brasil por meio da Agência Nacional de Vigilância Sanitária (Anvisa). No ano de 2016, observou-se o maior número de casos totais para ambas as doenças. A prospecção tecnológica nacional revelou que há interesse global em desenvolver tecnologias para essas doenças e depositar suas patentes no Brasil, tendo as empresas como principais depositantes. Por sua vez, a prospecção tecnológica global mostrou que o ano de 2016 configura-se como importante marco na evolução do número de patentes para zika e chikungunya, sugerindo que as epidemias brasileiras estimularam o mundo no desenvolvimento de novos insumos para a saúde. Os Estados Unidos e a China são as principais jurisdições, tendo as universidades como maiores depositantes. A análise de produtos a nível global revelou que apenas dois chegaram ao mercado para zika e um para chikungunya, e as vacinas estão na categoria principal. A busca na Anvisa revelou que há mais produtos registrados para zika do que em comparação à chikungunya. Os principais fabricantes legais são empresas brasileiras, com pedidos de registro realizados principalmente pelas empresas DiaSorin S.p.A., ECO Diagnóstica Ltda. e Chembio Diagnostics Brazil Ltda. Apesar do visível estímulo à pesquisa, desenvolvimento e patenteamento gerado pelas epidemias de zika e chikungunya no Brasil, isso não garantiu a chegada de novos produtos ao mercado nem acesso da população a eles.

Medical innovations can reduce social inequalities in health: an analysis of blood pressure and medication in the HUNT study

This paper examines whether the use of blood pressure medication has an influence on social inequalities in blood pressure levels. In Norway, cardiovascular disease has for decades been associated with high mortality and social inequalities. High blood pressure is an important risk factor in this aspect, and prescription drugs have been established as a standard treatment of hypertension. We have seen population blood pressure levels fall, blood pressure inequality levels remaining stabile, and medication use increase. The paper uses panel data from the Nord-Trøndelag Health Study linked with registry data on education and income. Results from fixed effects regression analyses indicate that blood pressure medication overall has a levelling effect. The traditional social gradient is mainly found among non-users of medication. With blood pressure medication being plausibly at a late stage of its diffusion, these findings give some support to the hierarchical diffusion model, while they also imply the need for equal access to sufficient blood pressure treatment.

The role of Design Science Research Methodology in developing pharmacy eHealth services

The increasing focus on efficiency of care has prompted health systems to look for innovative solutions that yield maximum value for care. Integration of care and eHealth are seen as the most promising solutions in the high technological environment of the coming decades. Pharmacy services have been developed to a point where the face of community pharmacy has changed dramatically. Thus, service design and implementation has become an area of increased attention by Pharmacy practice researchers, and the arrival of eHealth concepts to Pharmacy is driving the need to find alternative ways to design new services. Moreover, known barriers and challenges remain when securing integration of pharmacy services with the health systems. In this paper, Design Science Research Methodology (DSRM), a user-centered alternative methodology to the design, development and implementation of health services, especially eHealth services, is presented. This alternative, originally from the Information Sciences field, has been adopted as a service design methodology in diverse settings, including health care. Here, case studies are used to explain how a DSRM process should be conducted in a health care setting, illustrating what methods to choose in each step of the process. Finally, the advantages of DSRM compared to other user-centered methodologies for service design are presented, hopefully prompting the discussion on the use of DSRM for the study of the implementation and sustainability of pharmacy services.

Toward an Understanding of Public Health Entrepreneurship and Intrapreneurship

This paper describes a framework used to understand public health entrepreneurship and intrapreneurship for the purpose of pedagogy and practice. To ground this framework in the academic literature, a scoping review of the literature was conducted with application of a snowball method to identify further articles from the bibliographies of the search results. Recurring themes were identified to characterize common patterns of public health entrepreneurship and intrapreneurship. These themes were design thinking, resource mobilization, financial viability, cross-disciplinary collaboration, and systems strengthening. Case examples are provided to illustrate key themes in both intrapreneurship and entrepreneurship. This framework is a starting point to further the discourse, teaching, and practice of entrepreneurship and intrapreneurship in public health. More research is needed to understand implications for power and privilege, capacity building, financing, scaling, and policy making related to entrepreneurship and intrapreneurship in public health.

The diffusion of innovative diabetes technologies as a fundamental cause of social inequalities in health. The Nord-Trøndelag Health Study, Norway

This study investigates patterns of adoption and diffusion of innovative health technologies by socioeconomic status (SES) in order to assess the extent to which these technologies may be a fundamental cause of health-related inequalities. Quantitative analyses examined SES-based inequalities in the adoption and diffusion of diabetes technologies. Diabetes data from three panels of the Nord-Trøndelag Health Study (HUNT), Norway, were combined with income and education data. Cross-sectional and longitudinal regression analyses were used to examine relevant inequalities. Cross-sectional analyses suggest often present SES-based gradients in the adoption of diabetes technologies, favouring high-SES groups. Statistically significant differences (p ≤ 0.05) were most often present when technologies were new. In a cohort followed from 1984 to 1997, high SES individuals were more likely to adopt insulin injection technologies but, due to modest sample sizes, these inequalities were not statistically significant after adjusting for age, gender, and duration of illness. Moreover, compared to low SES individuals, high SES individuals are more active users of diabetes technologies. Results suggest that SES-based variations in access and use of innovative health technologies could act as a mechanism through which inequalities are reproduced. This study provides a discussion of mechanisms and a methodological foundation for further investigation.

Towards more comprehensive health law and policy research

In this comment, and drawing on the papers in the special issue, we ask: what are the core questions for the future of research into health law and policy, and European health law and policy more specifically? We first sketch the general functions and values of health law and policy. We then outline how these functions and values are affected by globalisation and Europeanisation, on the one hand, and technological change and digitalisation, on the other. In light of these developments we carve out some questions for future research and the implications of this agenda for the academic community that is working on European health law and policy.

Developing and Implementing new TB Technologies: Key Informants' Perspectives on the Ethical Challenges

OBJECTIVE

To identify the ethical challenges associated with the development and implementation of new tuberculosis (TB) drugs and diagnostics.

METHODS

Twenty-three semi-structured qualitative interviews conducted between December 2015 and September 2016 with programme administrators, healthcare workers, advocates, policymakers, and funders based in the Americas, Europe, and Africa. Interviews were analysed using thematic analysis.

RESULTS

Divergent interests and responsibilities, coupled with power imbalances, are a primary source of ethical challenges; the uncertain risk profiles of new drugs present an additional one. Although this challenge can be partially mitigated through stringent pharmacovigilance, respondents highlighted that high-burden countries tend to lack the resources to facilitate safe implementation. Increased advocacy and community engagement are considered an ethical imperative for future TB development and implementation.

CONCLUSIONS

This project helps identify some of the ethical challenges of new TB technologies. It demonstrates that investigating ethical challenges through qualitative research is one way to apprehend the difficulty of implementing new TB technologies. Addressing this difficulty will require that those in positions of power reconsider their interests in relation to disempowered communities.

POLICY IMPLICATIONS

Efforts to build consensus regarding what values should underpin the global governance of TB research, prevention, and care are essential to facilitate the ethical implementation of new TB technologies.

Determinants of heterosexual men's demand for long-acting injectable pre-exposure prophylaxis (PrEP) for HIV in urban South Africa

Background

Heterosexual men in South Africa are a large key population to exposure to HIV, yet preferences for HIV pre-exposure prophylaxis (PrEP) among this population have not, to date, been investigated in the literature. This paper aims to explore HIV prevention preferences among heterosexual men in urban South Africa, as well as to examine the demand and characteristics of men who favour long-acting injectable (LAI) PrEP over condoms and oral PrEP.

Methods

Data were collected among 178 self-reported HIV-negative heterosexual men, who were given example products and information before being asked which they preferred. Multivariate logistic regression was used to analyse which characteristics were associated with product choice.

Results

48% (n = 85) of participants preferred LAI PrEP, while 33% (n = 58) and 20% (n = 35) chose oral PrEP and condoms respectively. Having children (marginal effect = 0.22; 95% CI [0.01, 0.44]) or having higher risk attitude scores (marginal effect = 0.03; 95% CI [0.01, 0.06]) was significantly associated with a choice of LAI PrEP, while those who had unprotected anal intercourse (marginal effect = − 0.42; 95% CI [− 0.57, − 0.27]) and those who were concerned with protection against other sexually transmitted infections over HIV (marginal effect = − 0.42; 95% CI [− 0.60, − 0.24]) appeared less likely to prefer LAI PrEP.

Conclusions

The results suggested a relatively high demand and theoretical acceptability for LAI PrEP among heterosexual men in urban South Africa, but there appeared to be fewer distinct predictors for the willingness to use LAI PrEP compared to studies conducted among gay and bisexual men and women. Nevertheless, the findings contribute to the mapping of the demand and determinants of heterosexual men’s preferences for novel antiretroviral-based prevention in sub-Saharan Africa, and the data could aid in the differentiated design of future HIV prevention strategies using LAI PrEP in conjunction with other methods.

Innovative technologies and social inequalities in health: A scoping review of the literature

The aim of this study was to systematically review the range, nature, and extent of current research activity exploring the influence of innovative health-related technologies on social inequalities in health, with specific focus on a deeper understanding of the variables used to measure this connection and the pathways leading to the (re)production of inequalities. A review process was conducted, based on scoping review techniques, searching literature published from January 1, 1996 to November 25, 2016 using MEDLINE, Scopus, and ISI web of science. Search, sorting, and data extraction processes were conducted by a team of researchers and experts using a dynamic, reflexive examination process. Of 4139 studies collected from the search process, a total of 33 were included in the final analysis. Results of this study include the classification of technologies based on how these technologies are accessed and used by end users. In addition to the factors and mechanisms that influence unequal access to technologies, the results of this study highlight the importance of variations in use that importantly shape social inequalities in health. Additionally, focus on health care services technologies must be accompanied by investigating emerging technologies influencing healthy lifestyle, genomics, and personalized devices in health. Findings also suggest that choosing one measure of social position over another has important implications for the interpretation of research results. Furthermore, understanding the pathways through which various innovative health technologies reduce or (re)produce social inequalities in health is context dependent. In order to better understand social inequalities in health, these contextual variations draw attention to the need for critical distinctions between technologies based on how these various technologies are accessed and used. The results of this study provide a comprehensive starting point for future research to further investigate how innovative technologies may influence the unequal distribution of health as a human right.

Technological innovations and the rise of social inequalities in health

Social inequalities in health have been categorised as a human-rights issue that requires action. Unfortunately, these inequalities are on the rise in many countries, including welfare states. Various theories have been offered to explain the persistence (and rise) of these inequalities over time, including the social determinants of health and fundamental cause theory. Interestingly, the rise of modern social inequalities in health has come at a time of great technological innovation. This article addresses whether these technological innovations are significantly influencing the persistence of modern social inequalities in health. A theoretical argument is offered for this potential connection and is discussed alongside the typical social determinants of health perspective and the increasingly popular fundamental cause perspective. This is followed by a proposed research agenda for further investigation of the potential role that technological innovations may play in influencing social inequalities in health.

Implementing an online pharmaceutical service using design science research

BACKGROUND

The rising prevalence of chronic diseases is pressing health systems to introduce reforms. Primary healthcare and multidisciplinary models have been suggested as approaches to deal with this challenge, with new roles for nurses and pharmacists being advocated. More recently, implementing healthcare based on information systems and technologies (e.g. eHealth) has been proposed as a way to improve health services. However, implementing online pharmaceutical services, including their adoption by pharmacists and patients, is still an open research question. In this paper we present ePharmacare, a new online pharmaceutical service implemented using Design Science Research.

METHODS

The Design Science Research Methodology (DSRM) was chosen to implement this online service for chronic diseases management. In the paper, DSRM's different activities are explained, from the definition of the problem to the evaluation of the artifact. During the design and development activities, surveys, observations, focus groups, and eye-tracking glasses were used to validate pharmacists' and patients' requirements. During the demonstration and evaluation activities the new service was used with real-world pharmacists and patients.

RESULTS

The results show the contribution of DSRM in the implementation of online services for pharmacies. We found that pharmacists spend only 50% of their time interacting with patients, uncovering a clear opportunity to implement online pharmaceutical care services. On the other hand, patients that regularly visit the same pharmacy recognize the value in patient follow-up demanding to use channels such as the Internet for their pharmacy interactions. Limitations were identified regarding the high workload of pharmacists, but particularly their lack of know-how and experience in dealing with information systems (IST) for the provision of pharmaceutical services.

CONCLUSIONS

This paper summarizes a research project in which an online pharmaceutical service was proposed, designed, developed, demonstrated and evaluated using DSRM. The main barriers for pharmacists' adoption of online pharmaceutical services provision were the lack of time, time management and information systems usage skills, as well as a precise role definition within pharmacies. These problems can be addressed with proper training and services reorganization, two proposals to be investigated in future works.

Developing sustainable global health technologies: insight from an initiative to address neonatal hypothermia

Relative to drugs, diagnostics, and vaccines, efforts to develop other global health technologies, such as medical devices, are limited and often focus on the short-term goal of prototype development instead of the long-term goal of a sustainable business model. To develop a medical device to address neonatal hypothermia for use in resource-limited settings, we turned to principles of design theory: (1) define the problem with consideration of appropriate integration into relevant health policies, (2) identify the users of the technology and the scenarios in which the technology would be used, and (3) use a highly iterative product design and development process that incorporates the perspective of the user of the technology at the outset and addresses scalability. In contrast to our initial idea, to create a single device, the process guided us to create two separate devices, both strikingly different from current solutions. We offer insights from our initial experience that may be helpful to others engaging in global health technology development.

Innovative newborn health technology for resource-limited environments

OBJECTIVES

To review medical devices addressing newborn health in resource-poor settings, and to identify existing and potential barriers to their actual and efficient use in these settings.

METHODS

We searched Pubmed as our principal electronic reference library and dedicated databases such as Maternova and the Maternal and Neonatal Directed Assessment of Technology. We also researched standard public search engines. Studies and grey literature reports describing devices for use in a low- or middle-income country context were eligible for inclusion.

RESULTS

Few devices are currently described in the peer-reviewed medical or public health literature. The majority of newborn-specific devices were found in the grey literature. Most sources described infant warmers, neonatal resuscitators, and phototherapy devices. Other devices address the diagnosis of infectious diseases, monitoring of oxygen saturation, assisted ventilation, prevention of mother-to-child transmission of HIV, assisted childbirth, weight or temperature assessment, and others.

CONCLUSION

Many medical devices designed for newborns in the developing world are under development or in the early stages of production, but the vast majority of them are not available when and where they are needed. Making them available to mothers, newborns, and birth attendants in resource-limited countries at the time and place of birth will require innovative and creative production, distribution, and implementation approaches.
