Introduction 

Standard Operating Procedures (SOPs) are a cornerstone of quality assurance in clinical trials, providing detailed, step-by-step protocols to guide the execution of tasks and processes. Their importance has been amplified by the globalization of clinical research, where data consistency and reproducibility across multiple research centers are paramount. These procedures aim to minimize errors and ensure reproducibility of results, which is particularly important in the context of globalized clinical trials where data are collected and analyzed across multiple centers worldwide. 

The analysis of this topic is essential due to increasing demands from regulatory bodies and the scientific community for high-quality and accurate clinical trial data. Incorrect data can lead to erroneous conclusions, negatively affecting the safety and efficacy of new drugs. In the context of increasingly complex clinical protocols and exponentially growing data volumes, the standardization and rigorous quality control of processes have become indispensable for maintaining the integrity and reliability of clinical trial outcomes. SOPs facilitate the unification of data collection and processing methods, thereby enhancing data consistency and reliability. 

Modern clinical trials face challenges related to managing large volumes of data, adhering to diverse regulatory requirements, and ensuring data consistency across various research centers. Implementing SOPs helps address these challenges by providing standardized approaches to task execution and improving data quality control. The use of automation technologies and artificial intelligence within the framework of SOPs offers opportunities to enhance the efficiency of monitoring and data management. 

The purpose of this study is to analyze the role of standard operating procedures in ensuring the quality of clinical trial data. The article examines existing approaches to the development and implementation of SOPs, their impact on data accuracy and reproducibility, and explores the potential of new technological solutions for optimizing these processes.

Materials and Methods 

The standardization of operating procedures (SOPs) in clinical projects is addressed in the scientific literature from various perspectives. The authors propose methods for implementing these standards, analyze their application, and offer solutions for process optimization. In the study by Khin N. A. et al. [1], the importance of adhering to international standards in clinical research, including the principles of Good Clinical Practice, is emphasized. The authors examine aspects of ensuring data reliability and highlight the roles of monitoring and verification as critical stages for completing studies. The text also discusses the influence of digital technologies on improving the reliability of collected information. 

L. Houston and colleagues [2,3] focus on data systematization, considering SOPs as a tool for maintaining data consistency. Their work analyzes the experiences of research groups and the impact of monitoring on final results. Ugo F. et al. [5] identify SOPs as a foundation for improving management mechanisms in professional activities. AbuHalimeh A. [6] describes structural stages that enable a unified approach to data processing. 

Technical aspects of SOPs are explored in publications related to automation. Ulbrich F. et al. [4] describe a data quality control tool that is easily integrated into workflows. Kane M. J. [11] developed a methodology ensuring a standardized approach to analysis, addressing inconsistencies in data processing. 

Centralized monitoring is discussed by Bryant K. E. et al. [9], who underscores its importance for improving the reliability of control procedures. The article by Duggineni S. [10] highlights the role of SOPs in ensuring data integrity, which significantly impacts the success of clinical project implementation. 

The work by Abhishekar M. et al. [7] is dedicated to the efficiency of centralized data monitoring in the context of source material verification during clinical trials. Various methods of organizing control are presented, including traditional approaches and the use of centralized systems for monitoring at different stages of research. The authors emphasize that centralized solutions improve work speed and reduce data verification costs. They also stress the importance of maintaining data integrity throughout all stages of clinical trials, from preparation to analysis. 

Regional specifics of SOPs are covered in publications such as Kalugina, M. [8], which reflects the Russian experience in creating standards for nurses aimed at improving operational accuracy. Liu J. et al. [12] explore the nuances of data monitoring in Chinese medicine, taking into account cultural and regulatory peculiarities. 

However, the application of SOPs is accompanied by unresolved challenges. The literature lacks sufficient evidence confirming the universality of standards across various project types. Technical approaches, such as automated checks, remain in conceptual stages and require further practical development. 

The research methodology combined an extensive literature review, qualitative analysis of professional practices, and quantitative statistical methods. The literature review identified key trends and innovations in SOP development and implementation, while qualitative methods captured expert insights into the practical impact of SOPs. Quantitative analysis further validated the correlation between SOP adoption and measurable improvements in data accuracy and reproducibility. A comparison of national and international methodologies revealed the specific features of standard applications.

Results and Discussion

The safety of clinical research sites is of paramount importance, alongside the utmost efforts to obtain and transmit valuable information about the effects of drugs on human health. Throughout the entire lifecycle of clinical trials, research personnel must perform a wide range of activities and evaluations while maintaining and preparing research documentation. The high workload of researchers and limited time complicate the ability to address all aspects of study implementation, leading to disruptions in monitoring the progress of participants or accurate maintenance of research documentation [4]. 

Clear instructions for assessing various symptoms and predefined points for discussion with patients during site visits are essential. This ensures that significant data is identified, accurate information is collected, and no adverse effects, drug reactions, or events of special interest are overlooked, while also maintaining proper documentation practices. 

Patients often fail to notice, ignore, or omit some symptoms, disregarding changes since the start of treatment out of fear of treatment discontinuation. Studies may be disrupted due to social factors, cultural differences, or withholding information due to a lack of understanding of its importance or previous negative experiences. Therefore, every effort should be made to assist patients in reporting any deterioration or onset of symptoms throughout the study period. 

In some cases, patients do not disclose to investigators and conceal critical data, such as alcohol consumption, the use of antidepressants, neuroleptics, anxiolytics, mood stabilizers, stimulants, cannabinoids, herbal supplements, or any other prohibited medications specified by the protocol, due to fear of judgment, embarrassment, or social stigma. Additionally, the absence of a unique electronic medical record database in Georgia, accessible to treating physicians, significantly increases the risk of incomplete data collection regarding previous or ongoing treatments and hospitalizations. 

Standard operating procedures (SOPs) provide a foundation for structured task execution, prevent errors, and establish a clear sequence of actions. Their use is especially important when research involves multiple countries with varying approaches to medical practices [8]. The structure of these documents varies depending on the tasks, project nature, and institutional characteristics. Table 1 below illustrates the impact of SOPs on data accuracy.

Standard operating procedures (SOPs) establish orderliness in actions, eliminating ambiguity in task execution within clinical processes. Their application mitigates the influence of human factors and ensures structured operations. For instance, the use of microbiological monitoring methods and catheterization as prescribed by SanPiN 3.3686-21 simplifies data processing and reduces the likelihood of errors. To evaluate the quality of SOP implementation, a coefficient is calculated using the following formula:

Where: 

- KQI indicates the level of correctness in the collected information, 

- N_correct reflects the number of data points recorded without violations, 

- N_total represents the total number of processed indicators. 

To enhance the effectiveness of regulations, the use of automated control systems based on machine learning algorithms is proposed. The introduction of simulators for staff, modeling the consequences of deviations from procedures, is also considered a valuable tool. 

The success of SOP implementation largely depends on the qualifications of specialists and the regular updating of procedures based on new data. For example, adherence to ICH GCP guidelines demonstrates that strict compliance with established standards minimizes protocol deviations and ensures data organization [4,11,12]. 

SOP implementation requires continuous adaptation to current tasks and the application of modern technologies to improve accuracy and procedural adherence. Table 3 below outlines the prospects for the development of standard operating procedures.

Periodic Summary of SUSARs (Suspected Unexpected Serious Adverse Reactions): 

This summary consolidates safety data over a defined period (e.g., six months). It includes a line-by-line list of all suspected unexpected serious adverse reactions (SUSARs) associated with the investigational product during the period and an accompanying letter summarizing changes in the safety profile. These summaries should be submitted at least twice a  year to the Ethics Committee after the study's initiation.

Urgent Safety Measures (USM): 

These measures involve notification, assessment, communication, reporting, follow-up, documentation, and recording. USMs are taken in response to new events likely to affect the safety of subjects. Such events may arise from: 

- Significant deviations from Good Clinical Practice (GCP) guidelines, such as major protocol violations. 

- A cluster of adverse reactions a single instance of an unexpected serious adverse reaction, or an increase in the intensity or frequency of expected reactions deemed medically necessary. 

Investigators are required to take appropriate urgent safety actions to protect subjects from immediate hazards. These actions are procedures not defined in the protocol and may be implemented immediately without prior approval from the Ethics Committee (LEC), depending on the circumstances. 

In such cases, the investigator may alter the study procedures without prior approval from the Regulatory Authority (RA) or Local Executive Committee. Pre-approval from the LEC is essential to ensure subject safety and data integrity. Simultaneously, the investigator must inform the clinical research department head and instruct them to notify the local ethics committee by phone. The committee chair should convene an emergency meeting, and the institution must submit a detailed medical report to the LEC for review while informing the Sponsor as soon as possible, but no later than 24 hours. 

Guidelines for Preventing Serious GCP Violations and Managing Medically Critical Reactions: 

These instructions ensure the timely mitigation of significant protocol deviations or adverse reactions requiring urgent medical action.

To avoid human error during the implementation of a protocol or pharmacy instructions, a step-by-step procedural worksheet for distribution, preparation, and administration should be created and provided to authorized site personnel. This worksheet will require the presence and quality verification of a second staff member during dosing over several days. Both delegated and authorized team members involved in administration will sign the worksheet to confirm adherence to the pharmacy guidelines. Quality verification should include the following: 

- Printing and signing the IRT notification. 

- Comparing the number of packages listed in the attached report with the physical count retrieved from the refrigerator. 

- Handwriting subject information, visit date, site number, and name on the package label, with the empty packaging retained for further verification. 

- Completing all steps listed in the administration/preparation tables, with appropriate checkmarks. 

- Documenting the time of package removal from the refrigerator. 

- Documenting the time when package preparation is completed. 

- Documenting the start and end times of administration. 

- Closely monitoring the patient via intravenous observation during infusion and for two hours afterward. 

- Conducting intravenous infusion in an intensive care unit equipped with a seven-channel multiparametric ECG monitor, oxygen support, emergency medications (e.g., epinephrine, amiodarone, atropine, vasopressin, adenosine, lorazepam), an intubation kit, and a defibrillator to ensure reliable interventions and medical assistance by intensive care specialists to mitigate immediate dangers [10]. 

Standard Operating Procedures (SOPs) form the foundation for data management organization. They ensure consistency, minimize errors, and promote process unification. For a successful SOP application, it is necessary to account for project-specific characteristics, technological advancements, and a balance of stakeholder interests.

Conclusion 

SOPs serve as tools to regulate the collection, processing, and analysis of information. Their implementation reduces the risk of errors and promotes the reproducibility of results. The analysis of existing SOP implementation approaches underscores their importance for unifying methodologies in multicenter trials amid the globalization of medical research. 

This study underscores the transformative impact of SOPs on clinical trial management, demonstrating their capacity to enhance data quality control at every stage of the research process. The integration of automated monitoring systems and artificial intelligence further amplifies these benefits, providing a robust framework for future advancements. The use of automated verification systems and artificial intelligence technologies expands monitoring capabilities and improves the accuracy of final results. 

The necessity for regular SOP updates due to technological advancements and new regulatory requirements is emphasized. Flexible development methodologies enable timely protocol adjustments, enhance process management, and improve coordination of actions. 

A successful SOP implementation requires a comprehensive approach encompassing standards development, staff training, procedural compliance monitoring, and timely updates. SOPs establish the foundation for data management systems, ensuring accuracy, structure, and repeatability, which contribute to the creation of safe medications and effective therapeutic methods. 

This study confirms the significance of SOPs for clinical trial specialists, quality managers, and regulatory representatives. Future development prospects focus on implementing technological solutions for process automation and integrating SOPs with digital systems and artificial intelligence algorithms.
