Abstract

Artificial intelligence (AI) is increasingly being used to improve the quality control of point-of-care diagnostics. This is caused by a number of factors, including the following: 1. AI can accelerate and improve testing accuracy. In comparison to humans, AI technology can review data more quickly and precisely, reducing errors and improving overall quality assurance. 2. When it comes to improving POC test findings on healthcare issues such as infectious diseases or medical crises such as heart attacks, AI can be used for sophisticated predictive analytics and modeling that aid in better decision-making. 3. Artificial intelligence facilitates process automation, increasing productivity and lowering labor costs in labor-intensive tasks such as testing and analyzing samples collected at point-of-care facilities. 4. The use of AI enables organizations implementing these solutions to gain insights from large volumes of raw diagnostic data generated faster and more accurately, allowing them to build solid frameworks around preventive care initiatives and significantly influence public health outcomes.5. Artificial intelligence (AI) has been demonstrated to be a useful tool for real-time monitoring systems that identify any problems with test results early so that they can be corrected before affected patients receive inaccurate diagnoses or treatment plans based on false information provided by diagnostic tests performed at points of care such as clinics or hospitals.Using these technologies would allow healthcare organizations to spend less on labor while still receiving exact diagnoses and rapid treatment delivery at a fraction of the cost that manual approaches required earlier.

Introduction:

AI has proven to be a long-lasting solution to several problems in laboratory medicine related to precision and accuracy. Artificial Intelligence has gone beyond the human limits to explore invisible errors and loopholes which they human eye passes by but even though has its limitations too [1]. With a focus on laboratory medicine, AI refers to using technology to analyze and interpret health-related data from electronic health records, medical imaging, wearable devices, and other sources and is also used in the developing world to improve diagnosis accuracy, personalize treatment plans, and predict disease outcomes [2].

Point-of-care testing (POCT) refers to medical diagnostic testing performed at or near the site of patient care rather than in a centralized laboratory setting [3] and quality control which is an essential part of it refers to the processes and procedures used to ensure that the results generated by a laboratory are accurate, reliable, and consistent is an aspect which are needed to achieve quality results in the sector of laboratory medicine [4]. POC diagnostic kits are portable, simple-to-use that yield results in a matter of minutes as they make it possible to diagnose and treat infectious diseases outside of lab settings. They are important in rural or resource-constrained locations where it may not be possible to access advanced laboratory facilities. They can also be utilized in primary care offices, urgent care facilities, and emergency rooms to guarantee that patients receive speedy diagnoses and treatments. They coming of POC diagnostic kits have transformed laboratory medicine and elevated patient care on a global scale [5] but here we are looking at the inclusion of artificial intelligence to step up the accuracy and precision in this POC devices.

Artificial Intelligence (AI) and machine learning (ML) algorithms on POC Diagnostics

The introduction of artificial intelligence (AI) and machine learning (ML) algorithms to Point of Care (POC) diagnostics have reshaped the healthcare sector drastically [6]. Point-of-care diagnostic tools offer not only more trustworthy but more accurate and precise and a rapid turnaround time [7]. AI and ML algorithms have proven to be able to process huge information, finding patterns, and spotting anomalies [8] which have been applied to POC diagnostics and have a substantial impact on them. AI algorithms have the ability to lower the likelihood of diagnostic blunders and boost the precision and quality of outcomes. By enabling the POC diagnostic kit to learn from data and adapt its output to each patient's needs, machine learning algorithms can enhance the functionality of the device. The sensitivity and specificity of diagnostic tests can be increased with the aid of AI algorithms. They can also help create personalized POC diagnostic kits in accordance with the requirements of the patient. For instance, AI algorithms can assess a patient's lifestyle, medical history, and other pertinent aspects to assess the possibility of a disease and prescribe certain diagnostic procedures [9].

A smart diagnostic kit that interacts with patients and offers real-time feedback can be created with the aid of ML algorithms. For example, a POC diagnostic kit can assess the patient's breathing patterns using ML algorithms and deliver immediate feedback on how to improve breathing habits. Patients with respiratory conditions like asthma can benefit most from this [10].

How has artificial intelligence and machine learning improved POC diagnostics

In every innovation there are always challenges which present itself. These technologies have recently demonstrated significant potential for enhancing POC diagnostics quality control tool. In recent years, artificial intelligence (AI) and machine learning (ML) have emerged as powerful tools that can enhance POC QC processes. This literature review aims to explore the advancements in AI and ML techniques that have improved POC diagnostics and ultimately have the potential to revolutionize healthcare quality control. These technologies have recently demonstrated significant potential for enhancing POC diagnostics quality control.

Improved Test Accuracy:

AI and ML techniques have been applied to POC diagnostics to enhance test accuracy through an automated analysis of test results. Traditional POC tests are often subjective and require manual interpretation, leading to potential human errors or inconsistencies. By leveraging AI and ML algorithms, a consistent and objective analysis can be achieved. For example, they existence of an ML model for diagnosing infectious diseases at POC, achieving an accuracy of 95%, thus outperforming human experts. This demonstrates the ability of AI and ML algorithms to augment human expertise, resulting in improved diagnostic accuracy at the point of care [11,12].
Real-Time Decision Support:

AI and ML algorithms also provide real-time decision support at the point of care, aiding healthcare workers in making accurate and timely clinical decisions. These algorithms learn from large datasets and generate predictions or recommendations based on the patient's condition, history, and test results. For example, an AI-based decision support system for diagnosing diabetic retinopathy at POC [13,14], allowing non-expert healthcare workers to accurately identify the condition and recommend appropriate interventions. Such real-time support reduces the chances of misdiagnosis and improves patient outcomes.
Error Detection and Quality Control:

AI and ML techniques have shown promise in detecting errors faster and ensuring quality control in POC diagnostics. Errors in test administration, interpretation, or documentation can lead to incorrect diagnosis and subsequent patient harm. By continuously monitoring POC tests, AI algorithms can detect potential errors, alert healthcare workers, and provide suggestions for corrective action. For instance, an AI-based QC system for rapid HIV testing that reduced false-positive rates by 40% [15]. This highlights the potential of AI in improving QC processes and minimizing diagnostic errors.

Examples of POC diagnostic kits that have incorporated AI/ML

Some kits which have incorportated AI/ML in their functioning are:

Flu Detection Kit Powered by AI: An AI-powered flu diagnosis kit has been created by a startup business called Langbo Technologies. It employs deep learning algorithms to examine nose samples from individuals who may be sick with the flu. The kit offers a rapid and reliable detection of the influenza virus, saving healthcare professionals time and lowering the likelihood of prescribing needless antibiotics [16].
Skin Cancer Biopsy Assessment Tool: An AI-powered tool has been created by a Stanford University research team to evaluate skin samples for the presence of skin cancer. Dermatologists can immediately identify skin cancer and begin treatment since the algorithm can precisely differentiate between benign and malignant lesions [17].
Organ dysfunction biochemical evaluation: For the early diagnosis of organ dysfunction, numerous AI-powered POC diagnostic kits are being created. For instance, the ASTUTE 140 meter is a POC diagnostic kit that uses AI algorithms to evaluate indicators of kidney and liver function, obviating the need for invasive testing and delivering quick, precise findings [18].
Tuberculosis diagnosis: An AI-powered POC diagnostic kit that can correctly diagnose TB in patients within an hour has been created by IBM researchers. The kit analyzes samples of patient sputum using machine learning algorithms and gives a real-time diagnosis of TB, allowing medical professionals to rapidly start treatment and stop the spread of the illness [19].
