📚 Background
Opportunistic infections (OIs) are a major cause of hospitalization and mortality among individuals living with HIV. The complexity of these infections, stemming from various pathogens and their diverse clinical presentations, poses significant challenges for timely diagnosis. Traditional diagnostic methods can be slow and may not adapt well to the varying clinical scenarios faced by healthcare providers.
🗒️ Study
This retrospective cohort study collected clinical data from HIV-infected patients at four healthcare organizations in China. The researchers aimed to develop a machine learning model capable of quickly identifying the presence of OIs, regardless of the specific type of infection. A total of twelve machine learning classification algorithms were employed to train and evaluate the model, with a focus on optimizing performance through feature reduction techniques.
📈 Results
The study found that both the five features based on Shapley additive explanations and those based on Permutation Importance explanations achieved the highest F1 scores when evaluated using the adaptive boosting classifier model. The F1 scores of 0.9016 and 0.9063 were notably higher than the best-performing traditional model, which had an F1 score of 0.8991.
🌍 Impact and Implications
The implications of this study are significant for the management of HIV-infected patients. By leveraging machine learning, healthcare providers can potentially diagnose opportunistic infections more rapidly and accurately, leading to improved patient outcomes. This model could pave the way for more personalized and effective treatment strategies, ultimately enhancing the quality of care for individuals living with HIV.
🔮 Conclusion
This study underscores the transformative potential of machine learning in the field of infectious disease diagnosis, particularly for opportunistic infections in HIV patients. The ability to quickly and accurately identify these infections can significantly impact patient management and outcomes. Continued research and development in this area are essential to fully realize the benefits of AI in healthcare.

A Machine Learning Model for Diagnosing Opportunistic Infections in HIV Patients: Broad Applicability Across Infection Types.
Abstract
Opportunistic infections (OIs) are the leading cause of hospitalisation and mortality among Human Immunodeficiency Virus-infected (HIV-infected) patients. The diverse pathogen types and intricate clinical manifestations associated present a formidable challenge to the timely diagnosis of these infections. This study aims to use machine learning techniques to develop a diagnostic model that quickly identifies whether HIV-infected patients have any type of OIs, without being limited to specific infections, thus adapting to various clinical scenarios. This study is a retrospective cohort study that collected clinical data from HIV-infected patients at four healthcare organisations in China. A total of twelve machine learning classification algorithms were employed for the purposes of model training and evaluation. Additionally, feature reduction was conducted through the implementation of an importance ranking, with the objective of eliminating any redundant features. In conclusion, both the five features based on Shapley additive explanations (procalcitonin, haemoglobin, lymphocyte, creatinine, platelet) and the five features based on Permutation Importance explanations (procalcitonin, lymphocyte, haemoglobin, creatinine, indirect bilirubin) achieved the highest F1 score when evaluated using the adaptive boosting classifier model. The scores on the test set were 0.9016 and 0.9063, respectively, which significantly outperformed the best 32-feature model, gradient boosting classifier, which had a test set F1 score of 0.8991.
