1. Introduction

Reputation plays a critical role in the health insurance industry, where the intersection of healthcare financing, cost considerations, and regulatory frameworks influences operational outcomes and stakeholder trust. While reputation is widely recognized as a key factor in business success, its specific relevance to health insurers remains underexplored, despite growing attention in management research, as highlighted by Veh [1 p. 316] and Chun [2 p. 94]. This review addresses this gap by systematically analyzing the determinants and outcomes of health insurers’ reputation, moving beyond financial metrics such as premium costs to explore its broader implications. Recognizing reputation and trust are distinct yet related concepts, we considered both in the conceptual framing of our research. While we privilege the term reputation, we refer to trust when it is the primary focus in the studies cited.

The importance of trust in health insurance systems was articulated by Arrow, who argued that trust is a necessary condition for the functioning of markets characterized by uncertainty and information asymmetry [3 pp. 965−366]. In this contexte, the financial consequences of health risks are delegated to third parties, placing individuals in a relationship of dependence that relies on trust. Building on this foundational insight, subsequent scholarship has expanded and refined Arrow’s argument. Hall [4] emphasizes that trust in healthcare and insurance contexts is not only a response to statistical or financial uncertainty, but also to the psychological vulnerability associated with illness and treatment. From this perspective, trust may emerge as a relational construct shaped by experiences of dependence, exposure, and perceived institutional integrity, thereby closely aligning with the notion of organizational reputation. Complementing these perspectives, institutional approaches such as Scharpf’s actor-centered institutionalism [5] highlight that reputation and trust are embedded within institutional contexts that structure actors’ incentives, constraints, and strategic interactions. In regulated insurance systems, reputation thus functions not only as an attitudinal outcome, but also as a strategic resource shaped by and responsive to institutional rules and policy environments.

More recent work in behavioral health economics shows that health insurance choices are strongly shaped by behavioral frictions, including information search costs, choice complexity, inertia, and limited awareness of plan attributes [6–8]. In this contexte, such frictions may increase the saliance of insurer reputation in shaping the relationship between policyholders and insurers. They also raised reflection about the adequacy of existing legislative and regulatory frameworks.

From a public health perspective, the reputation of health insurers extends beyond a business asset to a potential public health priority. A positive reputation can enhance customer retention, foster investor confidence, and improve employee satisfaction (1, p. 323). Moreover, it can strengthen collaboration with public health systems, promote compliance with preventive health measures, and support a culture of continuous improvement in healthcare practices [9]. Conversely, a poor reputation may increase regulatory scrutiny and undermine efforts to develop and implement effective health policies. These dynamics underscore the dual importance of reputation in shaping both business success and public health outcomes.

This scoping review aims to provide the first comprehensive synthesis of existing literature on health insurer reputation. Specifically, it seeks to identify the key factors shaping reputation and assess its impact on insurers, policyholders, and the broader healthcare system. By clarifying these determinants and exploring their consequences, the review aims to equip insurers with actionable insights for strategic reputation management and inform policymakers about how reputation can be leveraged to enhance health outcomes. Additionally, the study highlights critical gaps in the current literature, paving the way for future research to build a deeper understanding of this essential topic.

2. Method

To achieve the study’s objective, we conducted a scoping review, an approach ideally suited for mapping the extent and breadth of existing literature on a given topic – in this case, the reputation of health insurers [10]. Scoping reviews enables a comprehensive mapping of key themes and knowledge gaps, with a focus on conceptual and contextual dimensions. The review adhered to the PRISMA guidelines for scoping reviews (PRISMA-ScR) [11], ensuring a rigorous and structured methodology. By systematically exploring the diverse body of literature on health insurer reputation, this approach clarifies key concepts such as reputation and trust within the health insurance context and support the identification of critical gaps, therby providing a foundation for future research.

3. Results

The total number of entries listed after the search is 3385 (1837 on Scopus, 493 on PubMed and 1055 on Web of Science). The final search results were exported to EndNote, where 1000 duplicates and 83 ineligible records (70 prior to 1990) were automatically excluded. 270 duplicates were additionally manually removed.

The remaining 2032 records were assessed for eligibility, of which 1987 entries were excluded. The primary reason for exclusion was that the records focused on other types of insurance, accounting for 814 records. Additionally, 679 were excluded due to a lack of relevance to reputation or trust in health insurance, 353 because they were grey literature or not peer-reviewed, 125 because they were essays, and 16 for other reasons. In total, 45 studies were included in our analysis, as shown in Fig 1.

3.2. Data synthesis

Our analysis of the included studies identified 23 descriptive themes, which were further synthesized into two overarching analytical themes: “Determinants” and “Outcomes”. These analytical themes provide a structured framework to understand both the factors influencing health insurers’ reputation and the consequences of that reputation. Two studies focusing exclusively on the assessment of reputation were not included in this thematic synthesis [16,17].

“Determinants” refer to the underlying factors or characteristics that shape or influence the reputation of health insurers. These factors may arise from the perspectives of key stakeholders, including policyholders, insurers themselves, and healthcare providers. They encompass elements such as customer satisfaction, perceived service quality, corporate culture, communication strategies, and trust in healthcare providers. “Outcomes” reflect the effects or consequences of health insurers’ reputation on their operations, stakeholders, and the broader healthcare system. These include customer behaviors such as policyholder retention, willingness to pay, and enrollment, as well as aspects related to public trust, data sharing, and collaboration within healthcare systems.

To support this analysis, we included direct extracts from the studies that illustrate key findings. These extracts, systematically linked to their references, provide evidence-based examples of each descriptive theme.

For a consolidated view, Table 2 presents a detailed summary of the descriptive themes, categorizing them into determinants and outcomes. The table also includes selected extracts to exemplify how these themes are operationalized within the studies, offering insights into their practical implications and interconnections. In addition, Fig 2 presents a conceptual model illustrating how the identified determinants influence trust and reputation, and how these, in turn, are associated with behavioural and system-level outcomes.

3.2.1. Determinants.

A total of 20 studies have explored the factors that influence the reputation of health insurance providers, revealing a diverse range of determinants. To provide a comprehensive understanding of the findings, the determinants were grouped into three distinct categories based on their relevance to specific stakeholder groups. First, policyholders rely on factors such as demographics, health literacy, and satisfaction levels, which directly influence their trust and perception of insurers. Second, health insurers include organizational factors under the control of insurers, including service quality, communication strategies, transparency, and corporate culture. Third, healthcare providers encompass variables related to the quality of care, trust in providers, and their communication styles, which indirectly affect the reputation of insurers.

3.2.1.1. Determinants related to policyholders: Six surveys focused on the characteristics of policyholders, such as age, gender, family status, income level, religious affiliation, and ethnicity, and their relationship with trust in health insurers [19–24]. They were conducted between 2003 and 2020 found no or minor association with reputation or trust. Bes [24] reported no significant association between gender and trust. Similarly, Goold [20] found no connection between age, race, income level, and trust in insurers, highlighting a discrepancy with most studies where race has been associated with trust in doctors, medical research, and the broader healthcare system (21 pp. 69, 71). These may partly reflect contextual variations across countries, where socio-demographic factors such as gender or ethnicity interact differently with individual and institutional trust.

One demographic factor, education or health literacy, consistently appeared to play a role in shaping trust. This conclusion was supported by six surveys [19,23,26,27,29,30], two qualitative interview [25,28], and one mixed-method study [18] conducted between 2006 and 2025 across divers countries. Eseta (26 p. 9) found that higher education levels correlated with increased trust, a finding echoed by Mathur (27 p. 10), who observed higher trust among those with greater health insurance literacy. However, Goold’s 2006 survey (21 p. 69) in the USA presented a contrasting view, suggesting that individuals with lower education levels might have higher trust, although she also noted that greater knowledge of the insurance plan enhanced trust. Such discrepancy might be explained by different understandings of trust across educational groups, or to country-specific levels of insurance literacy and exposure to the health system.

The same surveys that studied demographic variables have investigated the association between health status and trust. According to Gabay (20 p. 87), health status has a minimal influence on trust in the insurer. Goold (21 p. 69) states that individuals who reported fair or poor health status exhibited lower levels of trust in their insurer compared to those who reported good, very good, or exceptional health status. These findings were consistent across studies conducted in Germany in 2020 [21] and the USA in 2003 [22]. However, Bes (25 p. 6) found no association between trust in health insurers and health status. This divergence may be due to differences in study populations, sample sizes, or contextual factors such as variations in healthcare system performance and insurance coverage across settings.

3.2.1.2. Determinants related to insurers: Some of the variables observed in the selected studies demonstrate a direct dependence with insurers. Policyholders’ satisfaction with their insurer, the quality of the services offered by the latter and the communication adopted all contribute to the health insurers’ reputation.

The association of satisfaction and reputation or trust is supported by five surveys conducted between 2002 and 2022 across different countries and continents. Eseta conducted a qualitative interview in Ethiopia in 2022 [25]. Each of these studies reported a positive association with reputation. This convergence of findings may indicate that satisfaction plays a meaningful role in shaping insurer reputation, despite differences in health system design and study settings. Similar patterns of convergence were observed for several other insurer-related determinants described below.

Quality or perceived service quality were examined in four of the aforementioned studies [19,25,31,32], as well as in eight other surveys conducted between 2002 and 2022 in five countries and four continents [34,18,24,26,33,35,36,55], along with one mixed-method study carried out in Cambodia [38]. All of these studies concluded a positive association between quality and reputation. Mathur (2018) also observed a positive association between convenience and cost of plan (27 p. 7). Choice in product or plan is another variable positively associate with trust. One survey conducted in USA and a study using a mixed-method approach done in Ghana reach consistent results [18,22].

Communication has been consistently associated to reputation and trust. A positive association is supported by five surveys conducted between 2002 and 2022, across divers health systems [21,24,31,33,35], along with a qualitative study in Ghana (2015) and a mixed-method study in Cambodia (2009) [18,38]. Findings from Seiferth indicate that company publicity increases trust (22 p. 3716), while Grundstrom highlights the influence of showing empathy and a transparent communication in fostering trust (35 p. 8). The methodological diversity of these studies may strengthen the robustness of this association.

Eseta [25] examined drop-out from the community-based health insurance and observed a negative association with trust. No significant association was found between trust and selection of the health insurer, as examined in studies by Gabay [19] and Eseta, or between trust and locus of control, as investigated by Gabay.

Trust is be considered as a component of reputation by Mathur, who examines in a survey [26] the variance of seven broad factors, which includes 24 statements, explaining the model studied. In this study, along with determinants such as plan cost and quality of service, trust is related to perceptions and beliefs. According to Mathur, trust accounted for 7% of the variability in reputation and measured the level of “faith” in plans and insurance providers (27 p. 6). This may reflect both the distinction previously discussed between trust and reputation and the heterogeneity of definitions used for these concepts across studies.

3.2.1.3. Determinants related to providers: Variables linked to providers were also examined in the selected studies. They are trust in physicians, perceived quality of providers and their communication. Three surveys done in Israel, India and USA [19,23,26] as well as one study using a mixed-method done in Ethiopia [18] observed a positive association between these variables and reputation, except for the providers’ communication, where no association was found. Gabay did not observed a significant association between perceived communication and trust [19].

Trust in the primary care physicians also appears to be a key factor associated with trust in the health insurers according to Gabay (20 p. 87). Balkrishnan further supports that changes in primary care physicians are positively associated with trust in insurance companies (23 p. 818). In his study, Fenenga suggests, that a poor quality of health care providers can lower the trust in insurer [18]. Taken together, these findings could potentially suggest that in systems where insurers and providers are closely linked, such as in integrated systems, provider performance may indirectly shape public perception of insurers.

Overall, ten determinants were identified as showing a consistent positive association with reputation (such as satisfaction, cost of plan, choice and communication), while one was linked to a possible negative association. Four determinants, including demographic variables (such as age and gender), locus of control, selection or type of health insurance, and providers’ communication style, showed no significant association with reputation. Two determinants present conflicting results. The association between education and literacy appears to be either negative or positive, depending on the study. Study results also vary for health status, showing either no association or a positive association.

3.2.2. Outcomes.

The majority of the studies, 32 in total, focus exclusively on or include an analysis of the outcomes related to insurer’s reputation. These studies have been categorized into seven sub-groups: choice (product and selective contracting); policyholder portfolio (enrolment, change insurance plan, retention and drop-out); willingness to pay; data sharing; willingness to approach health insurer for healthcare advice; attitude (active membership, seeking care from a non-primary care physician). To facilitate a comprehensive analysis of the results, the identified outcomes were classified into two distinct groups: those pertaining to behaviour and those associated with attitude.

The positive association between reputation and product choice or acceptance of selective contracting is supported by three studies [24,39,40]. According to Bes, greater trust among policyholders in their health insurance provider leads to increased acceptance of selective contracting by the insurer [24 p. 6]. Van der Hulst obtained contradictory results. He found no association between trust (in the industry or a specific insurer) and the choice of a policy with selective contracting [41 p. 10]. As both studies were conducted in Netherlands, the contradictory findings cannot be readily attributed to systemic or cultural differences. Moreover, differences in analytical focus are unlikely to explain this divergence, as both studies examine specific insurers rather than the insurance system as a whole. Finally, both studies focus on reputation rather than trust, further limiting the plausibility of conceptual differences as an explanation.

The most frequently studied outcome relates to the policyholder portfolio, encompassing enrolment, changes in insurance plans, retention, and drop-out, and was examined in 19 studies [18,42,24,26,29,37,38,43–53,54]. Across 11 countries representing diverse geographical and institutional contexts (S2 Appendix), these studies consistently observed positive associations with enrolment, plan changes, and retention, and a negative association with drop-out. This convergence of findings suggests that insurer reputation plays a meaningful role in shaping policyholder behaviour, beyond specific health system configurations.

Attitude, such as active membership and seeking care from non-primary care physicians, were examined in six studies carried out between 2004 and 2025, across 5 countries and continents [18,23,51,57–59]. Balkrishnan’s research suggests that higher levels of trust in an insurer increase the likelihood of seeking care from specialists rather than relying primarily on general practitioners (24 S. 818). In contrast to six studies reporting a positive association in which satisfaction is identified as a determinant of trust, Bhojak described an inverse directional relationship, with trust emerging as a determinant of satisfaction (57 S. 639).

One study, conducted in Myanmar in 2019 by Myint [55], and one in Tanzania by Nzowa [56], focused on willingness to pay and found a positive association with trust. According to Myint, the level of trust in the health insurance system is strongly correlated with the willingness to pay. The findings indicate that the higher the trust in the health insurance system, the greater the amount individuals are willing to pay for coverage (53 S. 354).

Finally, recent surveys explored the propensity to share data and seek healthcare advice from insurers [9,21,35]. All of these studies observed a positive relationship between these behaviors and insurer reputation.

4. Discussion

This scoping review offers a comprehensive overview of determinants and outcomes of insurer reputation. By clarifying the determinants that shape an insurer’s reputation and assessing their potential relevance, this study provides valuable insights for insurers seeking to enhance their reputational standing and for policymakers aiming to promote improved health outcomes. Finally, the research identifies existing gaps in the literature, thereby offering a foundation for future inquiries to contribute to a more comprehensive understanding of health insurers’ reputation. Detailed characteristics and associations for each determinant and outcome are presented in Table 1 and the Results section; the discussion below focuses on their interpretation, contextualization, and broader implications.

A first observation relates to the methodological approaches adopted, with a predominance of quantitative surveys over qualitative or mixed-methods designs. While such approaches offer scalability and statistical representativeness, their predominance is somewhat unexpected given the complexity and context-dependent nature of concepts such as reputation and trust.

A second observation concerns inconsistencies in the associations observed. Among the determinants, health literacy and health status warrant further consideration. One of the outcomes, choice (product choice, acceptance of selective contracting), is also subject to debate. In addition, inconsistencies emerge with regard to the directional relationship between certain closely related constructs, particularly trust and satisfaction. While most studies report a positive association in which satisfaction is identified as a determinant of trust, one study suggests an inverse relationship, with trust emerging as a determinant of satisfaction. This divergence points to an important conceptual and methodological challenge in the literature. Trust and satisfaction are closely intertwined constructs, and their temporal ordering is not always clearly specified. Depending on study design, analytical approach, and underlying theoretical assumptions, trust may be conceptualized either as an outcome of service experiences or as a pre-existing attitudinal disposition shaping subsequent satisfaction evaluations. The predominance of cross-sectional survey designs further limits the ability to disentangle these causal pathways.

These variations may stem from methodological heterogeneity across studies, including differences in sampling strategies, data collection modes, and analytical approaches. They may also reflect contextual influences, such as variations in health system structure, financing models, and cultural expectations regarding the roles of insurers and healthcare providers (S3 Appendix). Furthermore, conceptual definitions of trust and reputation are not always consistent across studies, which may lead to differences in measurement and interpretation. Acknowledging these potential sources of variation is important for situating the findings within their specific contexts and for informing the design of future research aiming to examine these determinants in a more comparable manner.

A third key finding involves mapping the determinants that shapes the reputation of health insurers. Indeed, while existing literature includes reviews on the concept of reputation, to the best of our knowledge, this study represents the first review specifically focused on the reputation of health insurers, providing an in-depth examination of the reputation of health insurance. Five reviews addressing health insurance and including the concept of reputation have been identified; however, reputation was not the central focus of these studies. Three studies addressed the barriers and facilitators associated with obtaining or renewing insurance [60–62]. Miti investigates the factors associated to individuals’ willingness to pay [63] and Conde analyses the factors that may influence the adoption of community health insurance [64]. As a result, several aspects related to the reputation of health insurers may have been overlooked.

Ten determinants emerged as consistently and positively associated with insurer reputation, most of which relate directly to insurers’ operations (e.g., corporate culture, service quality, communication, product structure). Knowing these determinants is crucial for health insurers’ managers, because they have a broad scope for action on these variables. The detailed breakdown of these associations is provided in Table 1; here, we focus on their strategic implications for insurers.

Health insurers have limited, or primarily indirect, influence over determinants related to policyholders and healthcare providers (e.g., providers’ perceived quality, communication, education, and health status). Despite limited control over these reputational determinants, understanding which factors that may contribute to reputation is crucial. Health insurers should consider initiatives to enhance their clients’ health literacy [65] and recognize the potential reputational relevance of healthcare providers’ quality [66]. This is particularly relevant in countries where the contractual relationship between providers and insurers is critical. Studies in the United States and Israel have explored these issues, and similar trends are emerging in other countries as capitation model projects gain prominence. Switzerland, though likely in an early stage, has initiated several projects aligned with this model (for example in Arc jurassien [67] or in Canton de Vaud [68].

A fourth key finding addresses the question of why reputation should be considered an important factor by both insurers and policymakers. First, the analysis of the outcomes reveals that the reputation of health insurers has a significant influence on various aspects of consumer behaviour, including dropout rates, retention, and enrolment. It is also associated with product selection, pricing and willingness to pay. These findings are consistent with broader research in insurance markets, which conceptualizes trust as an intangible asset shaping policyholder behaviour beyond purely contractual or financial considerations [69]. Considering the potential impact of reputation on these elements, it seems essential for health insurance managers to include their reputation in their development strategy [1,12]. Second, the willingness to receive health advice and the willingness to share data are also positively associate with trust. It should alert policymakers in terms of public health [70]. Finally, the analysis of reputation outcomes highlights another point through its gaps. None of the identified studies address the consequences in terms of policy. That could suggest a potential gap in the literature, concerning for instance the regulatory implications of insurers’ reputational standing. This issue is particularly important when considering its broader implications for public health. It could be hypothesized that a poor reputation among health insurers may lead to increased regulatory scrutiny, which could, in turn, affect the effectiveness of collaborative efforts between health insurers and other stakeholders within the healthcare system. Recent examples highlight this, especially in the realm of data processing – a subject briefly addressed in the reviewed studies, but primarily from the perspectives of policyholders and regulatory authorities. For instance, in 2024 and 2025, the Swiss parliament will deliberate on this issue, as evidenced in the referenced article [71].

Our findings resonate with broader debates in health services research and organizational behavior. Reputation, as explored in our study, may be understood not only as an outcome of service quality and communication but also as a potential strategic asset in health system governance. Theories of organizational behavior highlight how reputation contributes to institutional legitimacy [72], stakeholder trust [73,74], and competitive positioning [75]. In this light, health insurers’ efforts to cultivate a positive reputation align with broader principles of organizational identity and strategic management. Moreover, the observed emphasis on empathy, transparency, and service responsiveness links directly with patient-centered care models in health services research [76]. By bridging the fields of organizational studies and health services, our scoping review may provide insights into how insurer reputation might function both as a determinant and as a lever of system-level performance.

5. Implications

The findings of this review underscore significant implications for insurers, policymakers, and researchers, shaping a broader narrative around the importance of reputation in health insurance. For insurers, the evidence points to a clear mandate: understanding and addressing the determinants of reputation is not just an operational necessity but a strategic imperative. Insurers hold considerable control over several key determinants, including corporate culture, service quality, and product convenience. By fostering empathy and transparency within their organizations, enhancing the tangible benefits of their insurance products, and ensuring consistent, high-quality service delivery, insurers can directly influence their reputational standing. Moreover, strategic communication emerges as a pivotal tool. Clear, empathetic, and transparent messaging not only strengthens trust but also positions insurers as proactive partners in the healthcare journey of their clients.

Policymakers, too, have a vital role to play in recognizing the intersection of health insurer reputation with public health objectives. The findings suggest that reputation is not merely a business concern but a public health asset, influencing behaviours such as data sharing, health advice-seeking, and preventive care. For instance, in contexts like Switzerland, where debates around health insurer advertising and data privacy are ongoing, there is an opportunity to align regulatory frameworks with strategies that enhance reputational trust. Policymakers could also encourage initiatives that improve client health literacy or incentivize quality improvements among healthcare providers, recognizing that these efforts contribute not only to public health but also to the reputational resilience of insurers.

For researchers, this review highlights a critical gap in the existing body of knowledge. The predominance of survey-based studies underscores the need for more diverse research methodologies, particularly qualitative approaches that can capture the nuanced perspectives of policyholders, providers, and insurers. Future research should also explore the interplay between reputation and regulatory frameworks, shedding light on how trust in insurers influences policy outcomes and public health effectiveness. By adopting a more holistic and interdisciplinary approach, researchers can help build a comprehensive understanding of the mechanisms that underpin health insurer reputation, its determinants, and its far-reaching implications.

In sum, this narrative emphasizes the interconnected roles of insurers, policymakers, and researchers in leveraging reputation as a pivotal factor in shaping the future of health insurance and public health systems. Through coordinated efforts, these stakeholders can foster a more trusted and effective healthcare ecosystem.

6. Limitations

Specific limitations should be considered when analysing and interpreting the findings of this scoping review. This study aims to present an extensive overview of the existing literature regarding the broad topic of health insurance reputation. We are aware that the structure of a country’s health system affects how the subject is approached, leading to variation across studies. Significant variability is also observed in the methodologies of the studies, as well as in the number of individuals surveyed or interviewed, respectively. This limits any direct comparison. Additionally, the quality of identified studies varies, and the review does not include a critical appraisal, which may have resulted in the inclusion of lower-quality data. This factor should also be considered while interpreting the data. Another limitation is the inherent risk of missing relevant research. Despite employing carefully selected terms to capture the breadth of literature on this topic, the potential for overlooking some studies cannot be entirely eliminated. By including grey literature in our exclusion criteria, we may have introduced a publication bias, which could have resulted in an incomplete mapping of the available evidence. This should be taken in consideration, as the exclusion criteria of absence of “insur*”, “health plan” or “managed care” in the title. Manual screening was carefully conducted to minimize the risk of missing relevant records from related fields such as communication, health policy or health sciences; however, this risk cannot be entirely ruled out. As a result, certain strands of the literature may be underrepresented, which could have influenced the comprehensiveness and thematic structure of the evidence identified. This review relied on three databases, and while these were selected for their relevance and coverage, expanding the number of databases could have enhanced the comprehensiveness of the review and potentially identified additional relevant studies. In addition, consistent with the objectives of a scoping review, we did not conduct a formal critical appraisal of the methodological quality of the included studies. As a result, studies of varying design and rigor were mapped without differential weighting, which limits conclusions regarding the relative strength of the evidence and the robustness of individual associations. Findings should therefore be interpreted with caution, particularly when informing policy or strategic decision-making. Future research could benefit from expanding the number of databases used and from conducting systematic reviews focused on specific determinants or outcomes, including a formal evaluation of study quality.

7. Conclusion

The current literature on health insurance reputation highlights significant gaps in comprehensive evaluations of its determinants and outcomes. This review identifies key factors influencing reputation – such as corporate culture, product structure, service quality, and provider quality – many of which insurers can directly control. By fostering transparency, empathy, and effective communication, insurers can positively shape their reputation and enhance policyholder trust.

A strong reputation not only supports core business operations, such as policyholder acquisition and retention, but also plays a critical role in promoting preventive care. However, existing studies predominantly focus on business outcomes, with limited attention to the regulatory implications of insurer reputation. Exploring these implications could provide valuable insights into how reputation may influence healthcare systems and public health.

Future research should address these gaps by examining the regulatory and public health consequences of insurer reputation. A deeper understanding in this area would help align insurer practices with broader healthcare strategies, improving both service delivery and the adoption of preventive health measures.
