This study examines the impact of medical artificial intelligence (AI) on physician workload and the quality of patient care. A meta-analysis of empirical studies found that AI significantly reduces physician workload and diagnostic time by automating repetitive interpretation and documentation processes, freeing clinicians to focus solely on patients. Automated generative AI-based electronic medical record systems reduce documentation time by approximately 40%, while voice recognition and AI scribing technologies reduce patient charting time by 28.8%. This reduces administrative burden, a major cause of physician burnout, by more than 30%. In radiology, AI-based interpretation reduced the interpretation time for abnormal contrast-enhanced brain CT lesions by 11.23%, the interpretation time for lung lesions by 52.82%, and the analysis time for peripheral blood smears by 61%. Importantly, these time savings occur naturally and, in some cases, improve diagnostic accuracy for major diseases (e.g., lung nodules, brain lesions, and breast cancer). Furthermore, AI minimizes the workload of interpretation through its automatic filtering function. This includes a 77.4%–86.7% reduction in review time for pulmonary nodules, a 51.3%–72.9% reduction in endometrial slide screening time, and an 86% saving in manual review time for epilepsy electroencephalography evaluation. These findings confirm that AI is establishing itself as a reliable tool that simultaneously improves physician efficiency, diagnostic efficiency, and clinical accuracy. Therefore, future healthcare policies regarding AI should not simply focus on expanding the workforce, but should adopt a strategic approach, optimizing resource efficiency and building a more resilient healthcare system.

Background and Objectives:
The purpose of this study was to compare and analyze the 18- year change in the relative value scale (RVS) in otolaryngology in relation to other surgical departments so as to help make future policy decisions.Subjects and Method Data on RVSs and addition rates, the deparments of main managed care, frequency of practice, and number of specialists were collected for all surgeries and procedures conducted in 2004, 2008, 2013, 2018, and 2022. Among these, an analysis was conducted for nine surgical departments. The number of surgeries and procedure items, the median value of the RVS, and the usage amount (i.e., RVS of all items multiplied by the frequency of surgeries and procedures) were calculated.
Results:
Over the past 18 years, the increase in the number of surgeries, procedure items and RVS in otolaryngology has grown smaller than that in other surgical departments, and the usage has decreased very sharply; in essence, the usage per specialist has actually decreased compared to 18 years ago.
Conclusion
Compared to other departments, RVS in otorhinolaryngology has shown very little change over the past period of 18 years. It is necessary to reasonably increase the currently undervalued RVS in otorhinolaryngology, particularly focusing on surgeries and procedures.
3.From the ‘Essential Healthcare Policy Package’ to the ‘Healthcare Reform 1st Implementation Plan’

Essential medical care is a concept referring to indispensable medical care. World Health Organization has defined essential healthcare services as the evidence-based technologies needed to cost-effectively solve health problems. However, most countries have no such term that describes essential healthcare services. Rather, it has been used to efficiently allocate medical resources in countries with limited resources. Therefore, a clear definition of essential healthcare services must be accompanied by a specific purpose and a clear direction for the need. The target to whom medical services are to be provided, the region and institution to be provided, the content of medical services, and the purpose of provision should be distinguished. Recently, as public interest in essential healthcare services has increased, the government announced “the Essential Healthcare Policy Package” and “the 1st Healthcare Reform Implementation Plan” to specifically promote it. But concerns of feasibility and financial estimates are being raised. So, here, I analyze the government policy package and its 1st implantation plan, and suggest policy proposals for them.
