Abstract

The private healthcare sector in Romania, led by prominent players such as Medlife, Regina Maria, Medicover and Sanador, has become a cornerstone of the country’s healthcare system. However, achieving sustainability in this sector remains a challenge. This study evaluates sustainability practices in Romania’s private medical sector using the Triple Bottom Line (TBL) framework, comparing them to those of the EU, USA and Japan. Using statistical methods and benchmarking, we identify correlations between healthcare expenditures, financing schemes and sustainability metrics. A bibliographic review highlights global trends in sustainable healthcare management, including environmental, social and economic strategies and provides insights into the cost-effectiveness of green initiatives. Special focus is given to the role of technology in driving sustainability through innovations in telemedicine, digital health records and operational optimization. Using statistical methods (Pearson and Spearman correlation coefficients), we have performed an analysis of health expenditure data for EU countries, the USA and Japan. The dataset was extracted from the Organisation for Economic Co-operation and Development (OECD) data portal and included various health expenditure indicators, financing schemes and administrative data for all EU countries, the USA and Japan for the period 2018–2023. We have performed a structured analysis that explores correlations between these indicators, with a focus on financial schemes, expenditures and management sustainability. The analysis shows strong correlations between healthcare expenditures, financing schemes and administrative costs. Countries with efficient governance, balanced financing and proactive population health strategies (e.g., Japan and Nordic countries) demonstrate better management sustainability. However, countries like the USA and Eastern EU nations face challenges due to high administrative costs and inefficient financing models, respectively. Addressing these issues is critical to sustaining healthcare systems in the long term. The findings reveal that while Romanian providers excel in patient satisfaction and technological innovation, they lag behind their European counterparts in environmental sustainability and equitable access. Recommendations are proposed to address these gaps, drawing on successful strategies implemented in other European healthcare systems. This study fills a gap in the literature by providing a structured analysis of sustainability practices in Romania’s private healthcare sector, contextualized within a global comparative framework.

1. Introduction

Sustainability in healthcare management has emerged as a global priority, given the sector’s substantial environmental footprint, its role in addressing social inequalities and the rising economic pressures on healthcare systems worldwide. Globally, the healthcare industry is responsible for 4.4% of greenhouse gas emissions, along with significant resource consumption and waste generation, highlighting the urgent need for sustainable practices [1]. This study employs the Triple Bottom Line (TBL) framework, which emphasizes the balance between environmental, social and economic dimensions, to evaluate sustainability in Romania’s private healthcare sector. Achieving sustainability in healthcare requires balancing environmental, social and economic dimensions while incorporating innovative technologies and strategies tailored to local contexts.
This study aims to evaluate sustainability practices in Romania’s private medical sector and compare them with those of other European countries, the USA and Japan. Specifically, the study seeks to achieve the following:
  • Assess environmental, social and economic sustainability practices in Romania’s private healthcare sector, with a focus on prominent providers such as Medlife, Regina Maria, Medicover and Sanador.
  • Analyze health expenditure indicators and financing schemes in Romania relative to global benchmarks, identifying key correlations and sustainability challenges.
  • Explore the role of technology—including telemedicine, digital health records and AI in driving sustainability in healthcare.
  • Provide actionable recommendations for improving sustainability in Romania’s private healthcare sector by drawing on successful strategies from other countries.
Romania’s private medical sector has seen rapid growth, with major players like Medlife and Regina Maria driving technological innovation and patient satisfaction. However, challenges persist in areas like green infrastructure adoption and equitable access to care. By benchmarking Romania against countries such as Germany, Sweden, the USA and Japan, this study aims to provide actionable recommendations to address sustainability gaps.
By addressing these objectives, the study aims to contribute to the growing discourse on sustainable healthcare management and offer insights for policymakers, providers and stakeholders in Romania.

2. Materials and Methods

This article is based on three poles of research that have revealed interesting correlations and valuable ideas: a bibliographic review on sustainability in the healthcare management period 2013–2024, a statistical analysis of health expenditure indicators, financing schemes and administrative data for all EU countries, the USA and Japan for the period 2018–2023 and a benchmarking analysis to compare sustainability practices across Romania, EU countries, the USA and Japan. This study integrates the Triple Bottom Line (TBL) framework, health system resilience and systemic sustainability models to evaluate sustainability practices. These frameworks emphasize interconnectedness between governance, financing and service delivery, providing a foundation for this study. Health system resilience, defined as the ability of systems to absorb and adapt to shocks, is critical for ensuring long-term sustainability. This concept is particularly relevant for Romania given its challenges in equitable access and operational inefficiencies.
This systematic review was conducted in accordance with the PRISMA 2020 guidelines. The PRISMA checklist and flow diagram are included in the Supplementary Materials.

2.1. Bibliographic Review on Sustainability in Healthcare Management

A systematic bibliographic review was conducted following PRISMA guidelines using predefined inclusion and exclusion criteria. The primary objective of the bibliographic review was to identify and analyze academic literature, reports and credible sources that address key themes, including the following:
  • Climate change and healthcare (e.g., carbon footprint and green hospitals).
  • Healthcare innovations (e.g., AI, telemedicine and electronic health records).
  • Public–private partnerships in healthcare.
  • Health equity and sustainability in healthcare systems.
These themes align with the need to understand how healthcare institutions can integrate sustainability, technology and equitable healthcare access while addressing global challenges like climate change.
The systematic review process followed the PRISMA 2020 guidelines to ensure transparency and replicability. We identified relevant studies through a comprehensive search of multiple databases (PubMed, Scopus, Web of Science and Google Scholar) and organizational websites. A total of 447 articles were initially identified and the selection process involved the removal of duplicates (134 articles), screening of titles and abstracts (187 articles excluded) and a full-text review of 126 articles. Ultimately, 39 articles met the eligibility criteria and were included in this review. The PRISMA flow diagram (Figure 1) provides a detailed overview of this process.

2.2. Statistical Analysis of Health Expenditure Indicators, Financing Schemes and Administrative Data for All EU Countries, USA and Japan for the Period 2018–2023

The statistical analysis utilized health expenditure data for EU countries, the USA and Japan, extracted from the OECD data portal. The dataset covered the period from 2018 to 2023 and included indicators such as Current Health Expenditure (CHE) as a percentage of GDP, Compulsory Health Insurance (CHI) as a percentage of CHE, General Government Expenditure (GGE) as a percentage of GDP, governance and administrative costs and capital health expenditure (public vs. private). These indicators were chosen based on their relevance to sustainability in healthcare systems. The dataset used includes the following key indicators:
  • Current Health Expenditure (CHE) as % of GDP: Measures the share of healthcare spending relative to the country’s economic output.
  • Compulsory Health Insurance (CHI) as % of CHE: Indicates the reliance on mandatory health insurance schemes to finance health expenditures.
  • General Government Expenditure (GGE) as % of GDP: Reflects the overall government spending relative to the economy.
  • Governance, Health System and Financing Administration (in million USD): Represents the administrative costs associated with governance and health financing.
  • Capital Health Expenditure: Divided into domestic public and domestic private expenditure.
  • Population (in thousands): Provides context for per capita calculations and comparisons.
To understand the relationships and sustainability of health financing and expenditures, the following analyses were performed: correlation analysis between indicators using statistical methods like Pearson or Spearman correlation coefficients, which helped us evaluate the relationships between the indicators, regional and country-level observations and Capital Health Expenditure (public vs. private). We employed Pearson and Spearman correlation analyses to evaluate the relationships between healthcare expenditure indicators and sustainability metrics. Pearson correlation coefficients were used to assess linear relationships (e.g., CHE as a percentage of GDP vs. CHI as a percentage of CHE), while Spearman’s rank correlation was applied for non-linear relationships (e.g., CHE as a percentage of GDP vs. governance costs). A significance level of p < 0.05 was used to determine statistical significance.
The selection of these statistical methods aligns with prior studies, such as Topol (2019) [2] and Purohit et al. (2021) [3], which emphasize the role of correlation analysis in identifying key factors influencing healthcare sustainability. For example, Topol (2019) [2,4] highlights how correlation analysis can reveal inefficiencies in healthcare systems, while Purohit et al. (2021) [3] demonstrate its application in evaluating the environmental impact of telemedicine adoption. This alignment with established methodologies enhances the validity and reproducibility of our findings. To ensure transparency, we have detailed the methodological approach, including the selection of data sources, statistical tools (IBM SPSS Statistics 28, R 4.2.2, Python 3.11.3) and visualization techniques. The structured methodology provides a robust framework for future studies to replicate or build upon this research.

2.3. A Benchmarking Analysis of Sustainability Practices Across Romania, EU Countries, the USA, and Japan

A benchmarking analysis was conducted to compare sustainability practices across Romania, EU countries, the USA and Japan based on key indicators such as environmental initiatives and strategies, healthcare accessibility and reliance and the way the sustainability policy is integrated in management.

3. Results

3.1. Results of Bibliographic Review on Sustainability in Healthcare Management

The bibliographic review highlights global trends in sustainable healthcare management, including environmental, social and economic strategies and provides insights into the cost-effectiveness of green initiatives. Special focus is given to the role of technology in driving sustainability through innovations in telemedicine, digital health records and operational optimization.

3.1.1. Environmental Sustainability in Healthcare Management

  • Environmental sustainability focuses on reducing the ecological footprint of healthcare facilities through energy efficiency, waste management and sustainable infrastructure. The World Health Organization (WHO) emphasizes that hospitals are among the most energy-intensive buildings, accounting for a significant share of global energy consumption [1,5,6,7,8,9]. Green hospitals are critical in reducing healthcare’s environmental footprint, with renewable energy adoption reducing emissions by 25% in participating facilities [10,11,12,13]. Developed countries such as Germany, Sweden and the Netherlands have pioneered green healthcare initiatives [12,14]. For instance, Germany’s “Green Hospital Program” incentivizes private and public hospitals to adopt energy-efficient technologies and renewable energy sources, contributing to a 25% reduction in emissions in participating hospitals between 2015 and 2022 [12,15,16,17].
  • Similarly, Sweden’s healthcare sector has integrated renewable energy into 80% of its facilities, significantly reducing its carbon footprint [12,14,18]. The Netherlands has adopted circular economy principles in healthcare, with hospitals recycling up to 70% of their medical waste and reusing medical devices where feasible [19]. However, in low- and middle-income countries (LMICs), limited financial resources hinder the implementation of green practices [5,20]. Despite these challenges, global initiatives like Healthcare Without Harm and the Global Green and Healthy Hospitals Network promote environmentally sustainable practices worldwide, offering frameworks for reducing waste, energy use and carbon emissions [10,12,21].

3.1.2. Social Sustainability and Healthcare Equity

  • Social sustainability in healthcare involves ensuring equitable access to services for all population groups, addressing disparities in care delivery and supporting workforce well-being. Research by Marmot (2020) [6] highlights that inequities in healthcare access are exacerbated in privatized systems, where higher-income groups benefit disproportionately [22,23,24,25]. Countries like Canada and Sweden have successfully integrated private providers into public healthcare systems, ensuring universal access through robust public–private collaboration [23,26,27,28].
  • Telemedicine has emerged as a vital tool for addressing healthcare inequities, particularly in underserved rural areas. Telemedicine reduces geographical barriers, enabling patients in remote regions to access specialized care [3,29,30,31,32]. During the COVID-19 pandemic, telemedicine adoption accelerated globally, improving healthcare access in both high- and low-income countries. However, challenges remain, including the digital divide and the need for infrastructure investment to expand telehealth services. Studies also highlight the importance of addressing digital equity in telemedicine adoption, especially in low-income regions.

3.1.3. Economic Sustainability in Healthcare Management

  • Economic sustainability in healthcare focuses on achieving financial viability while maintaining affordability for patients [24,33,34]. In countries like the United States and Switzerland, private providers have implemented value-based care models that prioritize patient outcomes while reducing costs [34,35,36,37]. Public–private partnerships (PPPs) have proven effective in reducing the financial burden on private providers while expanding access to care. For example, Germany’s PPPs [12,17] have facilitated the modernization of healthcare infrastructure, enabling private hospitals to access public funding for technology upgrades and facility expansions [22,38].
  • In low- and middle-income countries (LMICs), economic sustainability remains a challenge due to high operational costs and limited revenue streams. Research by the Organisation for Economic Co-operation and Development (OECD) indicates that governments in these countries must strengthen collaboration with private providers to improve healthcare access and sustainability [22,39]. The adoption of cost-optimization tools, such as AI-driven predictive analytics, has shown promise in reducing operational inefficiencies and improving resource allocation in hospitals worldwide [4,40,41,42]. Advanced waste management technologies, such as autoclaves and waste-to-energy systems, also provide dual benefits of environmental and economic sustainability [43,44,45,46,47,48].

3.1.4. The Role of Technology in Driving Sustainability

  • Technology is a cornerstone of sustainability in healthcare, enabling providers to address environmental, social and economic challenges effectively. Innovations such as artificial intelligence (AI), the Internet of Things (IoT) and telemedicine have transformed healthcare delivery globally [2,4,49,50]. For instance, AI-powered tools are being used in the United Kingdom to predict patient demand, optimize staffing and reduce energy consumption in hospitals [51]. The adoption of electronic health records (EHRs) has streamlined patient management and reduced paper waste in countries like Germany, Sweden and the United States [35,52].
  • Moreover, telemedicine has enhanced access to care while reducing healthcare’s environmental impact by minimizing patient travel [53]. Studies show that telemedicine adoption in the United States has reduced carbon emissions associated with patient transportation by 18% annually. Blockchain technology is also emerging as a tool to enhance administrative efficiency and support data security in healthcare systems. These technologies not only improve efficiency but also support the long-term sustainability goals of healthcare providers [54].

3.2. Results of the Statistical Analysis of Health Expenditure Indicators, Financing Schemes and Administrative Data for All EU Countries, the USA and Japan for the Period 2018–2023

Along with the bibliographic review on sustainability, the statistical analysis conducted revealed important correlations between the indicators, which supports the findings and ideas from the bibliographic review.
The statistical analyses were conducted on the dataset to explore correlations between various indicators. Below are the detailed aspects of the analyses, including the employed software, statistical methods, significance levels and key findings.
The following software tools were employed for statistical analysis:
  • IBM SPSS Statistics (Version 28.0), used for calculating correlation coefficients (Pearson and Spearman) and performed descriptive statistics and regression analyses.
  • Microsoft Excel, used for data cleaning, preparation and preliminary visualization (e.g., trend analysis and bar charts), calculated basic descriptive statistics (e.g., means, medians and standard deviations).
  • R (Version 4.2.2), conducted advanced statistical tests, including multivariate analysis and visualizations, used libraries such as ggplot2 for data visualization and correlation for correlation matrices.
  • Python 3.11.3 (with Pandas, NumPy and SciPy libraries), utilized for exploratory data analysis (EDA) to identify outliers and trends, supported additional statistical validation for robustness.
Statistical Methods Employed [55,56]
  • Correlation analysis was used with the purpose of assessing relationships between key health expenditure indicators. Pearson correlation coefficients were used for linear relationships between two continuous variables: CHE as % of GDP vs. CHI as % of CHE. Spearman’s rank correlation was used for non-linear relationships or ordinal data: CHE as % of GDP vs. governance costs. A significance level (p-value) of 0.05 was used to determine statistical significance. Correlation values (r) were interpreted as follows:
0.0–0.3: Weak;
0.3–0.7: Moderate;
0.7–1.0: Strong.
  • Regression Analysis was used with the purpose of exploring the predictive power of one variable over another. For example, CHE as % of GDP predicting governance costs. The method employed was Linear Regression with the dependent variable governance costs (in million USD). The independent variable was CHE as % of GDP.
Key Metrics:
R2 (Coefficient of Determination): Explained variance.
Adjusted R2: Adjusted for the number of predictors.
Significance (p-value): A value <0.05 indicates a meaningful predictor.
  • Multivariate analysis was used for the purpose of assessing the combined impact of multiple indicators on sustainability metrics. The method employed was Principal Component Analysis (PCA), used to reduce dimensionality and identify key factors explaining variance in the dataset. The indicators included the following: CHE, CHI, GGE and governance costs.
  • Descriptive statistics were used to compute the mean, median, standard deviation and interquartile range for all indicators to summarize the data.
  • Trend analysis was used to evaluate how sustainability metrics evolved over time (e.g., CHE as % of GDP). Time-series analysis tracked changes in indicators from 2018 to 2023.
Indicators Analyzed
The following indicators from the dataset were analyzed:
  • Current Health Expenditure (CHE) as % of GDP—Measures the share of healthcare spending relative to economic output.
  • Compulsory Health Insurance (CHI) as % of CHE—Indicates reliance on mandatory health insurance schemes for financing.
  • General Government Expenditure (GGE) as % of GDP—Reflects overall government spending relative to GDP.
  • Governance Costs (in million USD)—Represents administrative costs associated with health financing.
  • Capital Health Expenditure (public vs. private)—Split into domestic public and private expenditures.
  • Population (in thousands)—Provided context for per capita calculations.
Results of Statistical Analysis
  • Correlation Analysis: CHE as % of GDP vs. CHI as % of CHE:
Pearson correlation coefficient (r): 0.82 (p < 0.01).
Interpretation: Strong positive correlation; countries with higher CHE ratios tend to rely more on CHI financing schemes.
Examples:
Germany: CHE = 12.6% of GDP, CHI = 77% of CHE.
Romania: CHE = 5.7% of GDP, CHI = ~62% of CHE.
CHE as % of GDP vs. governance costs.
Pearson’s correlation coefficient revealed a strong positive correlation (r = 0.82, p < 0.01). Countries with higher healthcare spending (CHE) tend to rely more on CHI financing schemes.
We have prepared a scatterplot in Figure 2 which illustrates the relationship between Current Health Expenditure (CHE) as a percentage of GDP and Compulsory Health Insurance (CHI) as a percentage of CHE for Romania, Germany, Sweden, the USA and Japan. Countries with higher CHE as a percentage of GDP, such as Germany and the USA, tend to rely more heavily on CHI financing schemes, whereas Sweden relies entirely on public taxation for healthcare funding.
Spearman correlation coefficient (r): 0.61 (p < 0.05).
Interpretation: Moderate correlation; higher CHE is associated with increased governance costs.
  • Regression Analysis
CHE as % of GDP (independent variable) predicting governance costs (dependent variable):
R2 = 0.68; adjusted R2 = 0.65.
p-value = 0.002 (<0.05).
Interpretation: CHE is a significant predictor of governance costs, explaining 68% of the variance.
  • Multivariate Analysis (PCA)
Key Findings:
Two principal components explained 82% of total variance.
Component 1: governance costs, CHE and CHI (strongly correlated).
Component 2: GGE and population.
  • Time-Series Analysis
Key Observations:
USA: CHE increased from 16.6% (2018) to 18.8% (2020) before declining to 16.5% (2022).
Romania: CHE increased steadily from 5.5% (2018) to a peak of 6.4% (2021), reflecting rising healthcare costs.
Statistical Limitations
  • Data Gaps: Missing 2023 data for some countries (e.g., Romania’s capital health expenditure).
  • Assumptions: Linear relationships were assumed for regression models, which may not fully capture non-linear dynamics.
  • Sample Size: Limited to EU countries, the USA and Japan, which may restrict generalizability.
  • Significance Threshold: A strict p-value cutoff (0.05) may overlook smaller but meaningful effects.
Relevance to this Article
  • The statistical analysis aligns with key findings in the bibliographic review.
  • Correlation between CHE and governance costs.
  • The findings highlight that higher CHE (e.g., USA and Germany) leads to higher governance costs, confirming the correlation analysis.
  • Time-Series Trends: The rising CHE in Romania and the USA, supported by the time-series analysis.
  • PCA Findings: The identification of governance costs and CHI as key contributors to sustainability aligns with the recommendations for optimizing administrative efficiency and financing models.
  • Policy Implications: Statistical findings support this article’s call for Romania to adopt hybrid financing models and reduce governance inefficiencies.

3.2.1. Key Observations in the Indicators Included in the Dataset

To understand the relationships and sustainability of health financing and expenditures, we conducted statistical analysis using Pearson and Spearman correlation coefficients and we evaluated the relationships between the indicators. Below are some key observations:
  • Current Health Expenditure (CHE) as % of GDP vs. Compulsory Health Insurance (CHI) as % of CHE:
Countries with higher CHE as % of GDP (e.g., USA, Germany and France) tend to have higher reliance on CHI financing schemes. For example, in Germany and France, CHI contributes over 75% to CHE. However, countries like Denmark and Sweden show 0% CHI, indicating reliance on other public financing mechanisms (e.g., taxation).
  • CHE as % of GDP vs. General Government Expenditure (GGE) as % of GDP:
A significant positive correlation exists between these two indicators. Countries with high CHE also exhibit higher government expenditure relative to GDP (e.g., France, Germany and Japan). Sustainability challenges arise when government spending on health increases faster than GDP growth.
  • CHE as % of GDP vs. Governance and Administration Costs:
A moderate correlation suggests that countries with higher CHE often allocate more resources to governance and administration costs. For example, the USA (USD 295 billion in 2018) and Germany (USD 21 billion in 2018) have the highest administration costs, and smaller EU countries like Luxembourg and Malta spend significantly less, indicating potential efficiencies in administration.
Figure 3 illustrates the variations in Current Health Expenditure (CHE) as a percentage of GDP across selected countries (Romania, Germany, Sweden, the USA and Japan) from 2018 to 2022. The data highlights significant disparities in healthcare spending levels, with the USA consistently spending the most and Romania lagging behind. These differences underscore the sustainability challenges faced by countries with varying levels of healthcare financing and administrative efficiency. The figure also visually supports discussions regarding Romania’s lower CHE compared to developed countries and its implications for sustainability.

3.2.2. Regional and Country-Level Observations

  • USA:
The USA spends the most on healthcare (over 16% of GDP in 2022), but CHI accounts for only ~53% of CHE. This reflects a fragmented financing system with high administrative costs. High administrative costs (~USD 300 billion annually) question sustainability, as these costs do not directly contribute to health outcomes.
  • EU Countries:
Countries like Austria, Germany and France exhibit strong reliance on public financing through CHI (over 75% of CHE). Nordic countries (e.g., Denmark and Sweden) rely on tax-based financing, as seen in their 0% CHI contributions. Eastern EU countries (e.g., Bulgaria, Romania and Latvia) have lower CHE as % of GDP (~6–8%) and lower administrative costs, but they may face challenges in service quality and accessibility.
  • Japan:
Japan shows a balanced system, with high CHE as % of GDP (USD 9 billion in 2018), which is relatively low compared to the USA, indicating efficiency. However, Japan faces sustainability issues due to its aging population, which increases demand for healthcare services [57].

3.2.3. Capital Health Expenditure (Public vs. Private)

  • Countries with higher public capital health expenditure (e.g., Germany and Denmark) tend to have lower private contributions, indicating a robust public financing system.
  • Countries with significant private capital health expenditure (e.g., USA and Latvia) may risk inequities in access to healthcare services.

3.2.4. Management Sustainability

Sustainability in health financing is influenced by the following:
  • Financing Models:
CHI-based systems (e.g., Germany and France) are more sustainable in countries with strong economies and high workforce participation.
Tax-based systems (e.g., Nordic countries) rely on efficient tax collection and equitable redistribution but may face challenges during economic downturns.
  • Administrative Costs:
High administrative costs (e.g., USA) reduce efficiency and sustainability. Countries with lower governance expenses (e.g., Japan and Nordic countries) allocate more resources to direct healthcare services.
  • Population Trends:
Aging populations (e.g., Japan and Germany) will increase healthcare demand, challenging the sustainability of current financing mechanisms.
Countries with declining populations (e.g., Bulgaria and Romania) may face reduced revenue from CHI premiums, impacting the availability of funds for healthcare.
The analysis shows strong correlations between healthcare expenditures, financing schemes administrative costs. Countries with efficient governance, balanced financing and proactive population health strategies (e.g., Japan and Nordic countries) demonstrate better management sustainability. However, countries like the USA and Eastern EU nations face challenges due to high administrative costs and inefficient financing models, respectively. Addressing these issues is critical to sustaining healthcare systems in the long term.

3.2.5. Relevance to Romania

While global examples provide valuable lessons, Romania’s private healthcare sector operates in a unique context. Providers such as Medlife, Regina Maria, Medicover and Sanador have made significant progress in improving patient outcomes and expanding access to care. However, they face challenges in addressing environmental inefficiencies, social inequities and economic pressures. This article has explored how Romania’s private medical sector can adopt global best practices to achieve sustainability while addressing the specific needs of the local population.
Table 2 compares key health expenditure indicators and sustainability practices across Romania, Germany, Sweden, the USA and Japan. It includes metrics such as Current Health Expenditure (CHE) as a percentage of GDP, Compulsory Health Insurance (CHI) as a percentage of CHE, General Government Expenditure (GGE) as a percentage of GDP, governance costs and environmental and social sustainability practices. The comparison provides insights into the disparities in healthcare sustainability between Romania and more developed healthcare systems.

3.3. Key Players in Romania’s Private Medical Sector and European Benchmarking

3.3.1. Major Private Players in Romania

The Romanian private healthcare sector is dominated by four key players:
  • Medlife: Romania’s largest healthcare provider with over 230 clinics, 14 hospitals and 33 laboratories. Medlife is known for its technological innovation and is expanding its network to underserved areas.
  • Regina Maria: Operating 70 clinics and 19 hospitals, Regina Maria emphasizes digital transformation and telemedicine, serving over 3 million patients annually.
  • Medicover: A multinational company with 37 facilities in Romania, Medicover specializes in corporate health programs and preventative care.
  • Sanador: Focused on tertiary care, Sanador operates the largest private hospital in Bucharest, offering advanced diagnostic and surgical services.

3.3.2. Sustainability Practices in Romania vs. EU Countries

Environmental Sustainability and Cost-Effectiveness
  • Romania: While providers like Medlife and Regina Maria have piloted renewable energy projects, only 15% of private healthcare facilities in Romania have adopted green building standards. Waste management programs remain underdeveloped, with limited recycling and energy recovery initiatives. The financial benefits of green practices are underutilized in the Romanian private healthcare sector. For instance, Medlife could adopt waste-to-energy initiatives, like those in Sweden, to reduce waste disposal costs while generating energy.
  • Germany: Hospitals participating in Germany’s Green Hospital Program report significant cost savings. For example, a medium-sized private hospital in Bavaria installed energy-efficient Heating, Ventilation and Air Conditioning (HVAC) systems and reported annual savings of EUR 350,000 in operational costs within five years of implementation [15].
  • Sweden: Swedish hospitals have achieved long-term economic benefits from renewable energy adoption. A case study from Karolinska University Hospital showed that switching to geothermal heating and cooling reduced energy costs by EUR 500,000 annually, with an ROI achieved in just four years. Sweden’s geothermal and solar energy systems serve as benchmarks for Romania.
  • Poland: Poland has started implementing green initiatives, such as Lux Med’s solar panel installations, which reduced energy costs by 15% in 2022. These savings were reinvested in expanding healthcare services in underserved areas [40,58].
The bar chart in Figure 4 compares the green building compliance rates across Romania, Germany, Sweden, the USA and Japan. Sweden leads with 80% compliance, followed by Japan at 60%. Romania lags significantly, with only 15% of private healthcare facilities meeting green building standards, highlighting the country’s opportunities for improvement in environmental sustainability.
Social Sustainability
