This scoping review compiled information concerning digital health technologies (DHTs) evolution to support primary health care (PHC) during COVID-19 and lessons for the future of PHC. The identified literature was published during the COVID-19 peak years (2019–2021), retrieved from PubMed, Scopus, and Google Scholar, as well as hand searched on the internet. Predefined inclusion criteria were used, thematic analysis was applied, and reporting followed the PRISMA for Scoping Reviews.A total of 46 studies were included in the final synthesis (40 articles, one book, two book chapters, one working paper, and two technical reports). These studies scrutinized various aspects of DHTs, entailing 19 types of DHTs with 20 areas of use that can be compressed into five bigger PHC functions: general PHC service delivery (teleconsultations, e-diagnosis, e-prescription, etc.); behavior promotion and digital health literacy (e.g., combating vaccine hesitancy); surveillance functions; vaccination and drugs; and enhancing system decision-making for proper follow-up of ongoing PHC interventions during COVID-19.DHTs have the potential to solve some of the problems that have plagued us even prior to COVID-19. Therefore, this study uses a forward-looking viewpoint to further stimulate the use of evidence-based DHT, making it more inclusive, educative, and satisfying to people’s needs, both under normal conditions and during outbreaks. More research with narrowed research questions is needed, with a particular emphasis on quality assurance in the use of DHTs, technical aspects (standards for digital health tools, infrastructure, and platforms), and financial perspectives (payment for digital health services and adoption incentives).

The SARS-CoV-2 pandemic has put unprecedented pressure on the hospital sector around the world. It has shown the importance of preparing and planning in the future for an outbreak that overwhelms every aspect of a hospital on a rapidly expanding scale. We conducted a scoping review to identify, map, and systemize existing knowledge about the relationships between COVID-19 and hospital infrastructure adaptation and capacity planning worldwide. We searched the Web of Science, Scopus, and PubMed and hand-searched gray papers published in English between December 2019 and December 2021. A total of 106 papers were included: 102 empirical studies and four technical reports. Empirical studies entailed five reviews, 40 studies focusing on hospital infrastructure adaptation and planning during the pandemics, and 57 studies on modeling the hospital capacity needed, measured mostly by the number of beds. The majority of studies were conducted in high-income countries and published within the first year of the pandemic. The strategies adopted by hospitals can be classified into short-term (repurposing medical and non-medical buildings, remote adjustments, and establishment of de novo structures) and long-term (architectural and engineering modifications, hospital networks, and digital approaches). More research is needed, focusing on specific strategies and the quality assessment of the evidence.

Healthcare workforce (HWF) shortages are the biggest challenges today in healthcare systems. Therefore, it is crucial to forecast the future needs of HWFs in order to plan accordingly. The purpose of this study was to identify, map, and synthesize the tools, methods, and procedures for measuring medical staff deficits in Europe. We used the Arksey and O’Malley scoping review methodology. Based on predefined criteria, 38 publications that were retrieved from multiple scientific databases, hand-searched on the internet, from relevant organizations, and scanned from references were considered. They were published between 2002 and 2022. There were 25 empirical studies, 6 theoretical papers, 5 reports, 1 literature review, and 1 guidebook. The majority estimated or measured shortages of physicians (14/38) and nurses (7/38) or looked at HWF generally (10/38). Various methods were used, including projections, estimations, predictions, simulation models, and surveys, which used tools such as special computer software or customized indicators, i.e., the Workload Indicators of Staffing Need method. Researchers estimated HWF shortages at both national and regional levels. Such projections and estimations were often based on demand, supply, and/or need. These methods and tools are not always suited to the needs of a country or medical facility, which is why they need to be further developed and tested.

Background: Changes to provider payment systems are among the most common reforms in health care. They are important levers for policymakers to influence the health system performance. The aim of this study was to identify, systematize, and map the existing literature on the factors that influence health-care provider payment reforms. Methods: A scoping review was conducted. Literature published in English between 2000 and 2022 was systematically searched in five databases, relevant organizations, and journals. Academic publications and grey literature on health-care provider payment reform and the factors influencing reform were considered. An inductive thematic analysis was applied to map the barriers and facilitators that influence payment reforms. Results: The study included 51 publications. They were divided into four categories: empirical studies (n=17), literature reviews (n=6), discussion/policy papers (n=18), and technical reports/policy briefs (n=9). Most of the studies were conducted in developed economy countries (n=36). The most frequently reformed payment method was fee-for-service (n=37), and the newly implemented methods included bundled payments (n=16), pay-for-performance (n=15), and diagnosis-related groups (n=11). This study identified 43 sub-themes on barriers to provider payment reforms, which were grouped into eight main themes. It identified 51 sub-themes on facilitators, which were grouped into six themes. Barriers include stakeholder opposition, challenges related to reform design, hurdles in implementation structures, insufficient resources, challenges related to market structures, legal barriers, knowledge and information gaps, and negative publicity. Facilitators include stakeholder involvement, complementary reforms/policies, relevant prior experience, good leadership and management of change, sufficient resources, and external pressure to introduce reform. Conclusion: The factors that influence health-care payment reforms are often contextual and interrelated, and encompass a variety of perspectives, including those of patients, providers, insurers, and policymakers. When planning reforms, one should anticipate potential barriers and devise appropriate interventions. Registration: The study was registered with the Open Science Framework.

Hospitals constitute an essential part of health systems. Although fragmented data indicate that hospitals in many European countries face financial problems, no structured, comparative data are available. The objective of this study was to identify, synthetize, and map the existing evidence on hospital financial performance (FP) across European countries. A scoping literature review was conducted, following standardized methodological guidelines and a previously published protocol. Four scientific databases (PubMed, Web of Science Core Collection, Scopus, and ProQuest Central) were searched to identify studies published since 2010. The inclusion criteria were as follows: (1) the focus is on hospital settings in a European country; (2) FP is measured at the hospital level using a defined ratio; and (3) it is a full text publication in English. After screening 3422 records, a total of 62 full text publications focusing on 13 European countries were included (53 empirical studies and nine policy/discussion papers or technical reports). The empirical studies focused on four main categories: (1) measuring and/or comparing hospital FP (n = 20/53); (2) identifying associations between FP and other hospital (mostly organizational) characteristics (n = 38/53); (3) analysing the impact of an event on hospital FP (n = 11/53); and (4) other, e.g. developing a comprehensive hospital performance matrix with FP as one of the dimensions (n = 6/53). The vast majority of empirical studies are quantitative, use secondary data sources, and apply single profitability indicators to measure FP. The results of the identified studies are often mixed and highly specific to context, data, and methods. Research evidence on hospital FP in Europe is available for a limited number of countries. The existing empirical studies focus mostly on analysing the relationships between hospital FP and other organizational characteristics (e.g., ownership and management style). Our review highlights two major research gaps: (1) a lack of evidence on associations between hospital FP and quality of care metrics; and (2) a need for more theoretical/conceptual work on composite FP metrics that are relevant for hospital care providers.

Results-based healthcare financing policies have been adopted in countries worldwide, including those with limited resources. We conducted a retrospective, semistructured interview study to evaluate healthcare providers’ experiences with Rwanda’s performance-based financing (PBF) policy and the factors influencing its implementation. Guided by the health policy evaluation model—context, content, process, and actors—as a deductive framework supplemented by inductive coding, we analysed data from 21 participants (doctors, n = 13; nurses, n = 5; midwives, n = 3). Providers described PBF as a key motivator, supplementing incomes, increasing accountability, and fostering teamwork to meet performance targets. PBF was credited with improving patient outcomes, particularly in incentivized services; however, concerns arose regarding disparities in service prioritization. Key facilitators of and barriers to the implementation of PBF were identified, providing insights into its operational dynamics. Strong political commitment and integration into national strategies, such as Imihigo, along with decentralization through district steering committees, were key contextual enablers, enhancing the program’s flexibility and alignment with local priorities. The content factors centred on a two-tiered contracting system, combining national accreditation processes with individual performance incentives. Process factors supporting PBF were characterized by decentralized evaluations, audits, and multilevel communication, which collectively bolstered accountability mechanisms. The engagement and capacity of stakeholders were highlighted as crucial to the success of PBF. Nonetheless, significant barriers, such as payment delays, manual documentation, untimely evaluations, insufficient training, limited provider participation in decision-making, and the exclusion of patients as stakeholders, were identified. These findings offer practical recommendations for policymakers aiming to improve or adapt provider payment mechanisms in similar contexts.
