Lung cancer causes about 18% of all cancer deaths worldwide. The United States has a large number of these cases. In 2020, nearly 1.8 million people died from lung cancer globally, according to the International Agency for Research on Cancer (IARC). In the U.S., smoking is the main cause of lung cancer, making up about 85% of cases. Other causes include secondhand smoke, jobs with risks like asbestos and radon, air pollution, family history, and some lung diseases.
One big problem is that lung cancer symptoms often show up late. This means that doctors find the cancer when it is already advanced, which makes treatment harder. The five-year survival rate in the U.S. is only 28.4% because many cases are found late. But if lung cancer is found early (stage 1), the chance of survival after five years goes up to about 60%. Even so, only about 27% of lung cancers are caught in time to improve chances of survival.
Finding lung cancer early is very important to help patients. Screening can find cancer before symptoms start. This leads to treatments that are less severe, lower hospital stays, and less cost.
LDCT is the main tool used to screen for lung cancer. It is mostly used for people at high risk, like heavy smokers aged 55 to 80. LDCT can detect lumps or growths in the lung that might be cancer. Studies show LDCT screening helps people live longer by finding cancer early. However, only about 16% of people who should get screened had LDCT tests in the U.S. in 2022.
Incidental pulmonary nodules are small lumps in the lungs found by accident during imaging for other reasons. These nodules may be harmless, but some are signs of early cancer. About 1.5% of IPNs may turn out to be cancer. This could mean tens of thousands of new lung cancer cases in two years. Unfortunately, up to 64% of these nodules do not get proper follow-up care. About two-thirds of patients do not get the recommended check-ups. This lack of follow-up causes late diagnoses and worse outcomes.
Doctors watch the size, shape, growth, and risk factors of nodules to decide what to do next. Groups like the Fleischner Society and the American College of Chest Physicians make rules for managing nodules. Small, low-risk nodules may just be checked regularly with imaging. Nodules with higher risk usually need more tests like biopsies.
Finding lung cancer early helps patients do better and lowers costs for healthcare systems. Early stage cancer needs less harsh treatment and fewer hospital stays. This saves resources like staff time and equipment.
Screening programs for cancers like breast, colorectal, and cervical have shown high survival rates when found early—often over 90%. Lung cancer survival is lower but early detection is helping close this difference.
Since healthcare costs in the U.S. are high, using good early detection can improve care while lowering expenses. This is important for administrators who manage budgets and follow healthcare rules.
Screening based on each person’s risk, like smoking history, age, and genes, works better than testing everyone. This approach avoids unneeded tests for low-risk people and helps high-risk patients get the care they need quickly.
For example, genetic tests can help decide how often to screen someone. AI tools can help by using lots of patient data to improve prevention, detection, and treatment.
Health providers, organizations, and policymakers must work together to fix these problems.
AI can analyze medical images quickly and accurately. It finds lung nodules faster and more reliably than usual methods. Some AI models have reached 94% accuracy. This helps radiologists avoid mistakes and identify possible cancer faster.
AI tools help doctors figure out a patient’s risk using images, patient background, history, and other data. These systems use guidelines, like those from the Fleischner Society, to suggest what to do next. They can recommend watching the nodule, doing a biopsy, or starting treatment right away. This helps make sure patients get the right care for their situation.
One big problem is patients not getting follow-up after nodules are found. AI workflows can send reminders and alerts to care teams. This means patients stay on track with check-ups. Automated systems help reduce patients being forgotten, especially in busy clinics.
AI also cuts down the time doctors spend on paperwork. Technologies can listen to doctor-patient talks and make notes automatically. Some health systems have shown doctors save about 34 minutes a day on documentation. This lets doctors spend more time with patients and reduces burnout. For example, one health system saw a 44% drop in doctors quitting after using AI tools.
Good early detection needs quick access to all patient data. AI linked with electronic health records (EHRs) helps share information between hospitals. In the U.S., systems like Epic connect over 600 hospitals through nationwide frameworks. This sharing speeds up communication and lowers repeated tests.
Lung cancer is a serious health problem in the U.S. Using early detection improves survival rates by allowing simpler and more effective treatment. Key parts of this approach include LDCT screening, managing incidental nodules, and personalized risk screening.
Healthcare managers and IT staff have an important job in adding these methods to daily practice. Using AI and automation can improve how accurately cancer is found, make sure patients get needed care on time, and reduce doctor workload. This leads to better care and better use of resources.
By using technology for early detection, medical practices can improve healthcare, save money, and most importantly, save lives.
AI is being utilized in healthcare to streamline various processes, improve clinician efficiency, enhance patient experience, and facilitate better care delivery through advanced tools.
Clinicians using AI charting with ambient listening technology, like at John Muir Health, saved an average of 34 minutes per day on documentation, significantly impacting their overall workload.
At UPMC, clinicians reduced their ‘pajama time’—the time spent on paperwork—by nearly two hours daily, allowing more focus on patient care.
Centralized medical records promote higher quality and personalized care by providing comprehensive patient information, making healthcare simpler for patients and providers.
Spartanburg Regional enhanced nursing efficiency by involving nursing leaders in decision-making, leading to time-saving changes like automated documentation that saved 9,000 hours annually.
Piedmont Healthcare achieved a remarkable 95.8% response rate for CMS-required pre-op surveys by providing multiple options for patients to complete them.
Sutter Health improved early lung cancer detection by systematically monitoring incidental pulmonary nodules found in scans, doubling their detection rate for early-stage cancers.
The implementation of AI tools, such as AI charting, led to a significant 44% reduction in physician turnover at John Muir Health, suggesting better job satisfaction.
Epic’s software connects 625 hospitals to the TEFCA Interoperability Framework, enabling seamless information exchange which is crucial for coordinated care.
Epic aims to design clinician-centered AI tools that lighten workloads while enhancing care delivery, aligning technology with the needs of healthcare professionals.
