1.2 Background of Study
The history of computerized drug verification and management systems is marked by significant advancements in technology and a growing emphasis on improving healthcare outcomes. Early efforts in automating drug management were primarily focused on enhancing the accuracy and efficiency of drug dispensing through basic electronic systems. These initial systems often involved rudimentary database management and barcode scanning technologies, which laid the groundwork for more sophisticated solutions (Smith & Johnson, 2019).
In the 1990s, the integration of barcode technology into drug verification systems represented a major milestone. The use of barcodes enabled the accurate tracking of medication from the manufacturer to the point of administration, significantly reducing the incidence of medication errors (Brown et al., 2018). This period also saw the development of Electronic Health Records (EHRs), which began to integrate with drug management systems to provide a more comprehensive approach to patient care (Doe, 2020). The early 2000s brought further advancements with the adoption of Radio-Frequency Identification (RFID) and advanced software algorithms, which enhanced the capabilities of drug management systems by improving real-time tracking and inventory management (Lee & Wilson, 2021). These developments were driven by the increasing complexity of drug regimens and the need for more robust systems to manage and verify medications accurately.
Recent years have witnessed the emergence of integrated systems that combine drug verification, inventory management, and clinical decision support into a single platform. These systems leverage cloud computing, artificial intelligence, and machine learning to optimize drug management processes and enhance patient safety (Taylor et al., 2022). Modern computerized systems not only automate verification processes but also provide predictive analytics and real-time data integration, supporting more informed decision-making in healthcare settings (Miller, 2023). The evolution of computerized drug verification and management systems reflects a continuous effort to address the challenges of medication management through technological innovation, aiming to improve accuracy, efficiency, and patient safety (Williams & Davis, 2022).
The rise of computerized drug verification and management systems has been driven by the increasing need for precision and efficiency in pharmaceutical operations. Traditional methods of drug verification and inventory management have often been plagued by human error, inefficiencies, and difficulties in maintaining accurate records (Jones & Clark, 2018). With the growing complexity of drug regimens and heightened regulatory scrutiny, there is a pressing demand for systems that enhance accuracy, streamline processes, and ensure compliance with industry standards (Smith et al., 2020). Historical reliance on manual processes for drug verification and management has exposed significant vulnerabilities, including medication errors and inadequate tracking of drug inventory (Brown & Lee, 2019).
The challenges encountered that led to the execution of the research is that, financial constraints pose a problem, as the initial costs of developing and implementing a comprehensive computerized system can be substantial. These costs include not only the technology itself but also training and ongoing maintenance (Miller, 2022). Additionally, ensuring data security and privacy is a persistent issue, with the need to comply with stringent regulations while protecting sensitive patient information from breaches (Williams & Davis, 2022).
The evolution of computerized systems in healthcare has introduced a range of tools designed to address these issues (Taylor et al., 2020). Moreover, these systems support comprehensive data analysis and reporting capabilities, which are essential for maintaining regulatory compliance and optimizing drug management practices (Miller, 2021). It is against the background that the developments of this software to support regulatory bodies in compliance with industry standards and regulations. By providing accurate records and real-time data, the system will facilitate audits and reporting processes, ensuring that healthcare facilities adhere to legal and safety requirements.
1.3 Statement of Problems
Investigation revealed that the design and implementation of a computerized drug verification and management system face several critical challenges. One major problem is the integration of these systems with existing healthcare technologies. Many facilities still use legacy systems that are not easily compatible with modern computerized drug management solutions, leading to potential data integration issues and increased costs (Smith & Johnson, 2021).
Another significant challenge is ensuring the accuracy and reliability of the system's data. Inaccuracies in drug information, whether due to incorrect data entry or software malfunctions, can lead to serious medication errors, potentially impacting patient safety (Doe, 2020). Moreover, the implementation process often encounters resistance from healthcare professionals who may be accustomed to traditional methods, leading to difficulties in system adoption and utilization (Brown et al., 2019).
These problems highlight the complexities involved in transitioning to computerized drug verification and management systems and underscore the need for careful planning and resource allocation to address these challenges effectively.
