Indonesia INTRODUCTION Integrating clinical trials into primary health care in Indonesia is an effort to improve equitable access to health services. The 2018 Indonesian Basic Health Survey highlights considerable disparities in health service utilization across regions, with Sulawesi Island experiencing more restricted access compared to regions like Java and Bali . Geographical and logistical challenges exacerbate the situation, limiting patient participation in clinical trials and demonstrating poor integration between trials and primary health services . This issue reflects a global trend, as similar challenges in equitable access to clinical trials are observed in regions like Sub-Saharan Africa and South Asia, where limited infrastructure and logistical barriers exacerbate disparities . By connecting these local challenges to global trends, this study underscores the broader relevance of addressing health service disparities in underserved regions. Several initiatives, such as electronic medical records and telehealth technologies, have been implemented to enhance clinical trial integration . However, geographical challenges, particularly in regions like Sulawesi, persist as significant obstacles. Unlike previous initiatives, this study introduces a novel collaborative framework that emphasizes local adaptability. While previous studies such as INA-RESPOND focused on general approaches, this research highlights strategies specifically tailored to the socio-cultural and geographical context of Sulawesi, bridging critical gaps in the existing literature . International studies indicate that targeted digital health tools and training programs are effective in addressing these challenges . Despite these efforts, the COVID-19 pandemic exacerbated health access disparities in Sulawesi, highlighting the urgency of tackling these issues through collaborative and innovative approaches . Existing studies have explored the role of training and transparent communication in improving patient participation in clinical trials. For example, the INA-RESPOND network demonstrated that targeted training programs and digital tools could address logistical barriers and empower remote patients to participate in trials . However, most of these studies have focused on densely populated regions, leaving significant gaps in understanding how to adapt these strategies to remote and underserved regions like Sulawesi. This study addresses these gaps by explicitly building upon prior initiatives and emphasizing localized approaches to clinical trial integration. By doing so, it bridges the gap between broader national efforts and the specific needs of underserved areas, ensuring that strategies resonate with the unique challenges of Sulawesi. Findings from global health research underscore the importance of tailoring interventions to local socio-geographical contexts to enhance their impact . This study seeks to address this knowledge gap by developing and evaluating a collaborative framework tailored to the geographical and cultural context of Sulawesi Island. Unlike previous initiatives, this framework emphasizes local adaptability and scalability, ensuring that strategies align with the specific needs of underserved Additionally, this approach highlights how localized adaptations not only address logistical barriers but also foster greater community engagement and acceptance, amplifying the potential impact of clinical trials in remote settings . This study builds upon previous initiatives such as INA-RESPOND by emphasizing locally adapted strategies tailored to the unique geographic and socio-cultural context of Sulawesi, ensuring greater relevance for remote regions . METHOD This study employed a quasi-experimental pretest-posttest control group design to evaluate the effectiveness of a collaborative framework for integrating clinical trials into primary health care in Sulawesi Island. Multiple data sources were utilized to ensure a comprehensive analysis. These included electronic health records (EHR. from primary health care providers, detailing patient health, medical history, treatments, and trial participation 4. Supplementary data from the 2018 Indonesian Basic Health Survey highlighted disparities in health service utilization between Sulawesi and other regions like Java and Bali . Qualitative data from interviews with providers and patients, as well as online surveys, captured local contextual challenges. Sampling Primary health care providers and patients from Sulawesi Island were selected using stratified sampling to ensure representation across diverse demographics and infrastructure conditions. Inclusion criteria for providers Page | 288 J. Public Heal. Pharm. : 287-296 included active involvement in primary health care and willingness to participate, while patients voluntarily participated after receiving detailed information about the study's aims and procedures. Ethical principles were strictly followed, and all participants provided informed consent. Research Stages This study utilized a quasi-experimental pretest-posttest control group design. Baseline data were collected from EHRs for both the intervention and control groups. The collaborative framework was then implemented in the intervention group, including training on digital health technologies and integration of trial data into EHRs. Finally, post-intervention data were gathered to evaluate changes in clinical trial participation and health outcomes using robust statistical methods. Statistical comparisons between baseline and post-intervention measures were conducted to assess the framework's effectiveness. Data Analysis Statistical analyses included paired t-tests to compare pre- and post-intervention data, logistic regression to assess factors influencing patient participation, and chi-square tests to examine correlations between the intervention and health outcomes. These methods evaluated changes in health parameters and participation rates, offering insights into the framework's effectiveness. Ethical Approval The study did not receive formal ethical approval from an institutional review board. However, ethical principles were adhered to throughout the research process. Participants were fully informed about the studyAos objectives, procedures, and the voluntary nature of their participation. Written informed consent was obtained, and data were anonymized to maintain confidentiality. Retrospective approval or formal documentation of ethical practices is recommended to enhance credibility and reproducibility in future publications. RESULTS Descriptive Statistics Table 1.

This suggests that the intervention effectively enhanced participation. Previous studies found that community-based interventions can significantly boost clinical trial participation . Additionally, interventions improving communication and offering incentives have been shown to increase participation . Expanding trial eligibility criteria and including Patient and Public Involvement (PPI) are crucial for ensuring diverse representation and enhancing accessibility . Psychological factors improve participant engagement despite limited changes in physical health indicators . Variations Across Regions Healthcare providers and facilities are unevenly distributed across Sulawesi. South Sulawesi has the highest proportion of providers . %) and facilities . %), while Central Sulawesi has the lowest . % and 10%, respectivel. These disparities likely impact the accessibility and effectiveness of health interventions. South SulawesiAos better resources and infrastructure may explain higher participation rates compared to Central Sulawesi8. Prior research supports the idea that resource allocation and infrastructure influence health service access and clinical trial participation . Comparison with Previous Studies The findings of this study align with prior research showing that community-based and educational interventions can significantly enhance clinical trial participation and health outcomes. For example, the reductions in blood pressure from 140/90 mmHg to 130/85 mmHg and blood glucose levels from 160 mg/dL to 140 mg/dL, as observed in this study, are consistent with recent research . However, our findings extend this evidence by addressing regional diversity and participation challenges among minority populations, particularly in Sulawesi, which faces logistical and resource allocation barriers . These results also surpass previous gains reported by Claramita et al. and Wulandari et al. , emphasizing the effectiveness of our intervention . Effectiveness of the Intervention The study demonstrated significant improvements in clinical trial participation and health indicators in the intervention group . Participation increased from 25% to 60%, compared to smaller gains in the control group. Additionally, reductions in blood pressure . rom 140/90 mmHg to 130/85 mmH. and blood glucose levels . rom 160 mg/dL to 140 mg/dL) underscore the success of the intervention . These outcomes highlight the potential of collaborative frameworks and patient navigators to improve health outcomes and address disparities . , particularly in underserved regions like Sulawesi. The chi-square test confirmed these findings with statistically significant p-values (<0. , aligning with previous studies that emphasize the role of community-based and educational interventions in enhancing health outcomes . Limitations and Cautions While this study provides meaningful contributions to understanding health interventions and clinical trial participation, several limitations should be acknowledged. First, the use of a quasi-experimental design, while appropriate for evaluating interventions, may introduce biases due to the lack of randomization . Second, the geographical challenges of Sulawesi, such as difficult terrain and limited transportation, could have influenced the recruitment process and limited the generalizability of the findings . Finally, the reliance on secondary data, such as electronic health records and surveys, may have introduced potential inaccuracies or missing information . Future studies should consider a randomized controlled trial design and address logistical barriers to strengthen the validity and applicability of the findings . Page | 293 A Collaborative Framework to Enhance Clinical Trial Participation and Health Equity in Sulawesi Island. Indonesia Recommendations for Future Research The collaborative framework presented in this study holds potential for replication in other underserved regions with similar socio-geographical challenges . However, successful implementation will require adequate infrastructure, such as reliable internet connectivity and trained healthcare providers . Policymakers should focus on expanding digital health tools and training programs to ensure scalability and sustainability of such frameworks . Moreover, fostering partnerships between local governments, healthcare institutions, and community organizations can further enhance accessibility and engagement in clinical trials . Future studies should also explore strategies to minimize the Hawthorne effect, such as blinding or additional controls, to reduce potential bias in participant behavior . CONCLUSION This study investigated the impact of a collaborative framework on improving clinical trial participation and health outcomes in underserved regions of Sulawesi Island and aimed to evaluate the effectiveness of tailored interventions in addressing healthcare disparities. The findings demonstrated a significant increase in participation rates from 25% to 60% in the intervention group, along with notable improvements in blood pressure and blood glucose levels, surpassing results from previous studies. Notably, the study highlighted the critical role of regionalspecific strategies, community engagement, and government-industry partnerships in optimizing implementation and ensuring equity. These results underscore the importance of tailoring interventions to local contexts, investing in digital health technologies, and providing targeted training programs for healthcare workers. Recommendations for practical implementation include establishing digital platforms for clinical trial registration, strengthening collaborations between government and private sectors to fund pilot programs, and enhancing the capacity of local healthcare providers through training initiatives. While this study provides valuable insights into integrating clinical trials into primary healthcare systems, certain limitations should be noted, such as the short duration of observation and the focus on a single region. Future research should focus on evaluating the long-term impact, scalability, and adaptability of this framework across diverse regions in Indonesia, potentially enhancing our understanding of effective healthcare models and informing national health equity strategies.
