Public health research that addresses chronic disease has historically underutilized and undervalued qualitative methods. This has limited the field's ability to advance ( a) a more in-depth understanding of the factors and processes that shape health behaviors, ( b) contextualized explanations of interventions’ impacts (e.g., why and how something did or did not work for recipients and systems), and ( c) opportunities for building and testing theories. We introduce frameworks and methodological approaches common to qualitative research, discuss how and when to apply them in order to advance health equity, and highlight relevant strengths and challenges. We provide an overview of data collection, sampling, and analysis for qualitative research, and we describe research questions that can be addressed by applying qualitative methods across the continuum of chronic disease research. Finally, we offer recommendations to promote the strategic application of rigorous qualitative methods, with an emphasis on priority areas to enhance health equity across the evidence generation continuum. Expected final online publication date for the Annual Review of Public Health, Volume 43 is April 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Australia spends more than $20 billion annually on medicines, delivering significant health benefits for the population. However, inappropriate prescribing and medicine use also result in harm to individuals and populations, and waste of precious health resources. Medication data linked with other routine collections enable evidence generation in pharmacoepidemiology; the science of quantifying the use, effectiveness and safety of medicines in real-world clinical practice. This review details the history of medicines policy and data access in Australia, the strengths of existing data sources, and the infrastructure and governance enabling and impeding evidence generation in the field. Currently, substantial gaps persist with respect to cohesive, contemporary linked data sources supporting quality use of medicines, effectiveness and safety research; exemplified by Australia’s limited capacity to contribute to the global effort in real-world studies of vaccine and disease-modifying treatments for COVID-19. We propose a roadmap to bolster the discipline, and population health more broadly, underpinned by a distinct capability governing and streamlining access to linked data assets for accredited researchers. Robust real-world evidence generation requires current data roadblocks to be remedied as a matter of urgency to deliver efficient and equitable health care and improve the health and well-being of all Australians.

This paper makes theoretical, empirical, and methodological contributions to the study of social policy diffusion, drawing on the case of social protection in Africa, and Zambia in particular. We examine a range of tactics deployed by transnational agencies (TAs) to encourage the adoption of cash transfers by African governments, at the intersection between learning and coercion, which we term ‘coercive learning’, to draw attention to the important role played by TA-commissioned policy drafting, evidence generation, advocacy, and capacity-building activities. Next, we argue for making individual agents central in the analysis of policy diffusion, because of their ability to reflect, learn, and interpret policy ideas. We substantiate this claim theoretically by drawing on practice theories, and empirically by telling the story of social protection policy diffusion in Zambia through three individual agents. This is complemented by two instances of self-reflexivity in which the authors draw on their personal engagements in the policy process in Zambia, to refine our conclusions about the interplay of structure and agency.

IntroductionA national act (Order SSI/1356/2015) regulating Post-Launch Evidence Generation (PLEG) studies was set in Spain in 2015. These PLEG studies are to inform decisions about technologies already included in the Benefit Portfolio of the Spanish National Health System (SNHS) in order to confirm/exclude/modify their terms of use. Once a PLEG is established the selected hospitals provide the technology according to a common protocol and register outcomes until the required sample size is reached.MethodsThe PLEG studies are prospective, observational and single arm studies on safety, effectiveness and cost-effectiveness of a technology in real practice. The technology is selected because of the identification of an evidence gap, usually through a health technology assessment (HTA) report made by an agency of the Spanish Network of HTA Agencies (RedETS). The execution of a PLEG is assigned to one of the RedETS Agencies, which is responsible of delivering annual reports and a final report when the objectives are reached.ResultsThe following six PLEG studies, all of them on medical devices, have been launched in Spain so far, i) Endobronchial valve for patients with persistent air leak; ii) Biodegradable esophageal stent; iii) Percutaneous mitral valve repair system by clip; iv) Left Atrial Appendage Closure Device; v) Sensor-based glucose monitoring systems for children with type 1 diabetes mellitus; vi) Left ventricular assist devices for destination therapy. Five studies will finish their data collection by the end of 2020 or during 2021.ConclusionsA new national procedure using PLEG has been made available in Spain facilitating the use of real-world evidence to inform national decision-making on the financing of selected technologies due to uncertainties about their effectiveness, safety, cost-effectiveness and organizational impact. The studies are requiring a high amount of coordination tasks, as they are involving an average of 21 hospitals each. The usefulness and suitability of this procedure to achieve its objectives must be evaluated once their results are available.

Abstract Background Whilst access to cannabis-based medicinal products (CBMPs) has increased globally subject to relaxation of scheduling laws globally, one of the main barriers to appropriate patient access remains a paucity of high-quality evidence surrounding their clinical effects. Discussion Whilst randomised controlled trials (RCTs) remain the gold-standard for clinical evaluation, there are notable barriers to their implementation. Development of CBMPs requires novel approaches of evidence collection to address these challenges. Real world evidence (RWE) presents a solution to not only both provide immediate impact on clinical care, but also inform well-conducted RCTs. RWE is defined as evidence derived from health data sourced from non-interventional studies, registries, electronic health records and insurance data. Currently it is used mostly to monitor post-approval safety requirements allowing for long-term pharmacovigilance. However, RWE has the potential to be used in conjunction or as an extension to RCTs to both broaden and streamline the process of evidence generation. Conclusion Novel approaches of data collection and analysis will be integral to improving clinical evidence on CBMPs. RWE can be used in conjunction or as an extension to RCTs to increase the speed of evidence generation, as well as reduce costs. Currently, there is an abundance of potential data however, whilst a number of platforms now exist to capture real world data it is important the right tools and analysis are utilised to unlock potential insights from these.

Abstract Background An Informatics Consult has been proposed in which clinicians request novel evidence from large scale health data resources, tailored to the treatment of a specific patient. However, the availability of such consultations is lacking. We seek to provide an Informatics Consult for a situation where a treatment indication and contraindication coexist in the same patient, i.e., anti-coagulation use for stroke prevention in a patient with both atrial fibrillation (AF) and liver cirrhosis. Methods We examined four sources of evidence for the effect of warfarin on stroke risk or all-cause mortality from: (1) randomised controlled trials (RCTs), (2) meta-analysis of prior observational studies, (3) trial emulation (using population electronic health records (N = 3,854,710) and (4) genetic evidence (Mendelian randomisation). We developed prototype forms to request an Informatics Consult and return of results in electronic health record systems. Results We found 0 RCT reports and 0 trials recruiting for patients with AF and cirrhosis. We found broad concordance across the three new sources of evidence we generated. Meta-analysis of prior observational studies showed that warfarin use was associated with lower stroke risk (hazard ratio [HR] = 0.71, CI 0.39–1.29). In a target trial emulation, warfarin was associated with lower all-cause mortality (HR = 0.61, CI 0.49–0.76) and ischaemic stroke (HR = 0.27, CI 0.08–0.91). Mendelian randomisation served as a drug target validation where we found that lower levels of vitamin K1 (warfarin is a vitamin K1 antagonist) are associated with lower stroke risk. A pilot survey with an independent sample of 34 clinicians revealed that 85% of clinicians found information on prognosis useful and that 79% thought that they should have access to the Informatics Consult as a service within their healthcare systems. We identified candidate steps for automation to scale evidence generation and to accelerate the return of results. Conclusion We performed a proof-of-concept Informatics Consult for evidence generation, which may inform treatment decisions in situations where there is dearth of randomised trials. Patients are surprised to know that their clinicians are currently not able to learn in clinic from data on ‘patients like me’. We identify the key challenges in offering such an Informatics Consult as a service.

Abstract Background Ensuring the right to respectful care for maternal and newborn health, a critical dimension of quality and acceptability, requires meeting standards for Respectful Maternity Care (RMC). Absence of mistreatment does not constitute RMC. Evidence generation to inform definitional standards for RMC is in an early stage. The aim of this systematic review is clear provider-level operationalization of key RMC principles, to facilitate their consistent implementation. Methods Two rights-based frameworks define the underlying principles of RMC. A qualitative synthesis of both frameworks resulted in seven fundamental rights during childbirth that form the foundation of RMC. To codify operational definitions for these key elements of RMC at the healthcare provider level, we systematically reviewed peer-reviewed literature, grey literature, white papers, and seminal documents on RMC. We focused on literature describing RMC in the affirmative rather than mistreatment experienced by women during childbirth, and operationalized RMC by describing objective provider-level behaviors. Results Through a systematic review, 514 records (peer-reviewed articles, reports, and guidelines) were assessed to identify operational definitions of RMC grounded in those rights. After screening and review, 54 records were included in the qualitative synthesis and mapped to the seven RMC rights. The majority of articles provided guidance on operationalization of rights to freedom from harm and ill treatment; dignity and respect; information and informed consent; privacy and confidentiality; and timely healthcare. Only a quarter of articles mentioned concrete or affirmative actions to operationalize the right to non-discrimination, equality and equitable care; less than 15%, the right to liberty and freedom from coercion. Provider behaviors mentioned in the literature aligned overall with seven RMC principles; yet the smaller number of available research studies that included operationalized definitions for some key elements of RMC illustrates the nascent stage of evidence-generation in this area. Conclusions Lack of systematic codification, grounded in empirical evidence, of operational definitions for RMC at the provider level has limited the study, design, implementation, and comparative assessment of respectful care. This qualitative systematic review provides a foundation for maternity healthcare professional policy, training, programming, research, and program evaluation aimed at studying and improving RMC at the provider level.
