RESUMEN
Background: The use of large language models like ChatGPT is becoming increasingly popular in health care settings. These artificial intelligence models are trained on vast amounts of data and can be used for various tasks, such as language translation, summarization, and answering questions. Observations: Large language models have the potential to revolutionize the industry by assisting medical professionals with administrative tasks, improving diagnostic accuracy, and engaging patients. However, pitfalls exist, such as its inability to distinguish between real and fake information and the need to comply with privacy, security, and transparency principles. Conclusions: Careful consideration is needed to ensure the responsible and ethical use of large language models in medicine and health care. The development of [artificial intelligence] is as fundamental as the creation of the microprocessor, the personal computer, the Internet, and the mobile phone. It will change the way people work, learn, travel, get health care, and communicate with each other. Bill Gates1.
RESUMEN
In order to address a long standing challenge for internal medicine physicians we developed artificial intelligence (AI) models to identify patients at risk of increased mortality. After querying 2,425 records of patients transferred from non-intensive care units to intensive care units from the Veteran Affairs Corporate Data Warehouse (CDW), we created two datasets. The former used 22 independent variables that included "Length of Hospital Stay" and "Days to Intensive Care Transfer," and the latter lacked these two variables. Since these two variables are unknown at the time of admission, the second set is more clinically relevant. We trained 16 machine learning models using both datasets. The best-performing models were fine-tuned and evaluated. The LightGBM model achieved the best results for both datasets. The model trained with 22 variables achieved a Receiver Operating Characteristics Curve-Area Under the Curve (ROC-AUC) of 0.89 and an accuracy of 0.72, with a sensitivity of 0.97 and a specificity of 0.68. The model trained with 20 variables achieved a ROC-AUC of 0.86 and an accuracy of 0.71, with a sensitivity of 0.94 and a specificity of 0.67. The top features for the former model included "Total length of Stay," "Admit to ICU Transfer Days," and "Lymphocyte Next Lab Value." For the latter model, the top features included "Lymphocyte First Lab Value," "Hemoglobin First Lab Value," and "Hemoglobin Next Lab Value." Our clinically relevant predictive mortality model can assist providers in optimizing resource utilization when managing large caseloads, particularly during shift changes.
RESUMEN
Background: The use of artificial intelligence (AI) in health care is increasing and has shown utility in many medical specialties, especially pathology, radiology, and oncology. Observations: Many barriers exist to successfully implement AI programs in the clinical setting. To address these barriers, a formal governing body, the hospital AI Committee, was created at James A. Haley Veterans' Hospital in Tampa, Florida. The AI committee reviews and assesses AI products based on their success at protecting human autonomy; promoting human well-being and safety and the public interest; ensuring transparency, explainability, and intelligibility; fostering responsibility and accountability; ensuring inclusiveness and equity; and promoting AI that is responsive and sustainable. Conclusions: Through the hospital AI Committee, we may overcome many obstacles to successfully implementing AI applications in the clinical setting.
RESUMEN
BACKGROUND: The role of artificial intelligence (AI) in health care is expanding rapidly. Currently, there are at least 29 US Food and Drug Administration-approved AI health care devices that apply to numerous medical specialties and many more are in development. OBSERVATIONS: With increasing expectations for all health care sectors to deliver timely, fiscally-responsible, high-quality health care, AI has potential utility in numerous areas, such as image analysis, improved workflow and efficiency, public health, and epidemiology, to aid in processing large volumes of patient and medical data. In this review, we describe basic terminology, principles, and general AI applications relating to health care. We then discuss current and future applications for a variety of medical specialties. Finally, we discuss the future potential of AI along with the potential risks and limitations of current AI technology. CONCLUSIONS: AI can improve diagnostic accuracy, increase patient safety, assist with patient triage, monitor disease progression, and assist with treatment decisions.
RESUMEN
BACKGROUND: Our objective was to identify perceptions of the environment for women in surgery among 4 academic institutions. METHODS: Faculty surgeons and senior surgery residents were randomly selected to participate in a parallel study with concurrent quantitative and qualitative data collection. Outcomes were perceptions of the environment for women in surgery. Measures included semi-structured interviews, survey responses, and responses to scenarios. RESULTS: Saturation was achieved after 36 individuals were interviewed: 14 female (8 faculty, 6 residents) and 22 male (18 faculty, 4 residents) surgeons. Men (100%) and women (86%) reported gender disparity in surgery and identified 6 major categories which influence disparity: definitions of gender disparity, gaps in mentoring, family responsibility, disparity in leave, unequal pay, and professional advancement. Overall 94% of participants expressed concerns with gaps in mentoring, but 64% of women versus 14% of men reported difficulties finding role models who faced similar obstacles. Over half (53%) reported time with loved ones as their biggest sacrifice to advance professionally. Both female and male respondents expressed system-based biases favoring individuals willing to sacrifice family. A global subconscious bias against the expectations, abilities, and goals of female surgeons were perceived to impede promotion and advancement. CONCLUSION: Both female and male surgeons report substantial gender-based barriers in surgery for women. Despite improvements, fundamental issues such as lack of senior role models, limited support for surgeons with families, and disparities in hiring and promotion persist. This is an opportunity to make substantive changes to the system and eliminate barriers for women joining surgery, advancing their careers, and achieving their goals in a timely fashion.
