Advancements in Colonoscopies

June is Men’s Health Month, a time dedicated to raising awareness about the unique health challenges men face and promoting preventative measures to ensure long and healthy lives. As part of this important initiative, we’re diving into one of the critical aspects of men’s health: advancements in colonoscopies.

Recent advancements in colon cancer detection have focused on improving the accuracy, accessibility, and non-invasiveness of screening methods. Here are some notable developments:

1. Liquid Biopsy and Blood Tests

Circulating Tumor DNA (ctDNA): Liquid biopsies that analyze ctDNA can detect genetic mutations associated with colon cancer. This method allows for early detection and monitoring of cancer without invasive procedures.
Blood-based Biomarkers: Researchers are identifying specific biomarkers in the blood that indicate the presence of colon cancer. Tests like the Epi proColon, which detects methylated SEPT9 DNA, have been developed and are being refined.

2. Stool-based Tests

Multitarget Stool DNA Tests (mt-sDNA): Tests like Cologuard analyze stool samples for DNA mutations and blood associated with colon cancer and precancerous polyps. These tests have high sensitivity and can be done at home.

Fecal Immunochemical Test (FIT): FIT detects hidden blood in the stool, a common sign of colon cancer. It’s non-invasive, easy to use, and more accurate than older fecal occult blood tests (FOBT).

multitarget FIT (mtFIT) test: Researchers at the Netherlands Cancer Institute have developed a new stool test that may detect signs of colorectal cancer earlier and more effectively than existing tests. Published in The Lancet, the study found that the multitarget FIT (mtFIT) test, which measures hemoglobin, calprotectin, and serpin family F member 2 levels, outperformed the current fecal immunochemical test (FIT). Among 13,187 participants, the mtFIT test identified more abnormal protein levels, suggesting better detection of pre-cancers and polyps. This advancement could lead to a significant reduction in colorectal cancer cases and deaths, improving early detection and survival rates. Further studies are needed to compare the mtFIT test with commercially available tests.

3. Advanced Imaging Techniques

Artificial Intelligence (AI) in Colonoscopy: AI-powered tools assist gastroenterologists during colonoscopies by enhancing polyp detection rates and reducing the likelihood of missing lesions.

High-Resolution Imaging: Techniques like narrow-band imaging (NBI) and confocal laser endomicroscopy provide clearer, more detailed views of the colon’s mucosal surface, improving the detection of subtle lesions.

4. Genetic and Molecular Testing

Next-Generation Sequencing (NGS): NGS technologies enable comprehensive genetic profiling of tumors, helping to identify specific mutations and guide personalized treatment plans.

Molecular Markers: Identifying molecular markers such as KRAS, NRAS, and BRAF mutations, as well as microsatellite instability (MSI), helps in assessing cancer risk and determining appropriate therapies.

5. Non-Invasive Imaging Techniques

Virtual Colonoscopy (CT Colonography): This non-invasive imaging technique uses CT scans to create detailed images of the colon and rectum. It’s a less invasive alternative to traditional colonoscopy and can be particularly useful for patients unable to undergo standard procedures.
Magnetic Resonance Colonography (MRC): Similar to CT colonography, MRC uses MRI technology to visualize the colon. It’s another non-invasive option, though less commonly used.

6. Enhanced Patient Accessibility and Comfort

At-Home Screening Kits: Innovations in at-home testing kits, like those for FIT and mt-sDNA, have made screening more accessible and convenient, potentially increasing participation rates in regular screening programs. Research led by the Perelman School of Medicine at the University of Pennsylvania found that colorectal cancer screening rates more than doubled when patients were given a choice between a take-home test or a colonoscopy, compared to offering only a colonoscopy.

Telemedicine and Remote Monitoring: The integration of telemedicine allows patients to discuss test results and next steps with healthcare providers remotely, improving follow-up care and reducing the need for in-person visits.

7. Artificial Intelligence and Machine Learning

AI Algorithms for Risk Assessment: AI is being used to develop algorithms that analyze patient data, including medical history, genetics, and lifestyle factors, to assess individual risk for colon cancer and recommend personalized screening schedules.

Improved Pathology: Machine learning models are enhancing the accuracy of pathology by analyzing biopsy samples for subtle signs of cancer that might be missed by human eyes.

These advancements are collectively improving the early detection of colon cancer, leading to better patient outcomes through earlier intervention and more personalized treatment plans.

Issues with Outpatient Imaging Appointments

A recent study published in Academic Radiology reveals that nearly 24% of outpatient imaging appointments are missed, with the majority due to patient cancellations rather than no-shows. Factors such as younger age, being unwed, residing in disadvantaged neighborhoods, or lacking adequate insurance increase the likelihood of missing appointments. The study, conducted by researchers at the University of California, Irvine, analyzed data from their academic health center, finding that over 70% of cancellations were initiated by patients. Interventions are suggested to reduce missed appointments, such as self-scheduling, implementing checklists for necessary processes before imaging exams, and addressing health-related social risks like transportation access. Despite suggestions, limited research exists on reducing appointment cancellations in outpatient imaging.

 

Delays in MRI Orders

A recent study published in the Journal of the American College of Radiology reveals that nearly half of outpatient MRI orders experience significant delays, being performed more than 10 days from the date chosen by the referring provider. Led by Ronilda Lacson, MD, PhD, from Brigham and Women’s Hospital in Boston, the research emphasizes the critical importance of mitigating factors causing these delays, as they negatively impact patient care. Assessing over 97,000 outpatient MRI exams ordered between October 2021 and December 2022, the study identifies patient demographics, social determinants of health, and radiology practice- and community-level factors associated with delayed MR imaging. The study found that close to 50% of MRI orders had a prolonged order-to-performed interval, with factors such as higher Area Deprivation Index (ADI) scores contributing to delays. The authors stress the need for systemic approaches to address disparities in access to MRI examinations, including staff training, access to patient navigators, and programs tackling transportation barriers to outpatient imaging.

 

Other Challenges Outpatient Centers Face:

 

Technological Advancements: Keeping up with rapidly evolving imaging technologies requires significant investment and ongoing training for staff. Outpatient centers need to stay updated with the latest equipment and software to maintain competitiveness and provide accurate diagnostic services.

An Update to the Physician Shortage Problem

The AAMC (Association of American Medical Colleges) has released new projections indicating a physician shortage of up to 86,000 physicians in the United States by 2036. This underscores the critical need for sustained and increased investments in training new physicians to address the country’s healthcare needs. The report, conducted by GlobalData Plc, includes various scenarios based on trends in healthcare delivery and the workforce. While the projected shortfall is smaller than previous estimates, it still highlights the necessity for additional investments in graduate medical education (GME). Demographics, particularly population growth and aging, are driving the increasing demand for physicians. The report also notes a significant portion of the physician workforce nearing retirement age, which will further decrease the physician supply. Addressing underserved communities could require approximately 202,800 more physicians than current estimates. Lifting the federal cap on Medicare support for GME and bipartisan legislation like the Resident Physician Shortage Reduction Act aim to alleviate the shortage, but further efforts are needed to meet future healthcare demands.

 

Rural Americans’ Healthcare Challenges

Rural Americans face significant healthcare challenges, with fewer available doctors compared to urban areas, exacerbating existing health issues. Dr. Bruce A. Scott, President of the American Medical Association, emphasizes the urgent need for policymakers to address these disparities. Rural communities experience higher rates of various illnesses, exacerbated by economic pressures and limited access to healthy living conditions. The shortage of specialists and the closure of rural hospitals further compound the problem. Insufficient access to primary care physicians is a pressing issue, with inadequate residency spots and decreasing applications from rural areas. The AMA advocates for changes to the Medicare physician payment system, which has seen a decline in rates over the years. Administrative burdens, such as prior authorizations, are also contributing to physician burnout and compromising patient care. To combat the doctor shortage and rural health challenges, the AMA advocates for healthcare reforms, including overhauling the Medicare payment system, expanding telehealth, increasing residency positions, incentivizing rural practice, and addressing workforce stresses.

History of the IHS: Indian Health Services

When experts study health across various U.S. demographics, one particular metric often falls into sharp relief: there is a significant health burden weighing on American Indians and Alaska Natives. The AI/AN population accounts for about 9.7 million people in the United States (about 2.9% of the population), and this group routinely ranks near the bottom for life expectancy, insurance coverage, and overall health (both mental and physical).

About 2.6 million of AI/AN people receive healthcare services from the IHS, or Indian Health Services. This program aims (to use their own words), “to raise the physical, mental, social, and spiritual health of American Indians and Alaska Natives to the highest level,” but is the program succeeding? Let’s examine the IHS and its mission, challenges, and efficacy.

The IHS Story

While the U.S. government and federally recognized tribes have worked in partnership to provide AI/AN people with healthcare since the 1700s, the IHS officially began its work in July of 1955. The organization first worked to build hospitals in remote parts of the country that served Native individuals in the area; over the years, the IHS has expanded its efforts to include both health services and public health education.

Today, the IHS is a part of the U.S. Department of Health and Human Services. They operate more than 600 medical facilities on or near Indian reservations across 37 states, and they also work to tackle challenges impacting AI/AN public health.

Challenges Facing the IHS

There’s no arguing that the IHS has laudable goals and that its team of 15,000 employees works hard to improve AI/AN lives. But IHS still faces significant challenges in its efforts. Research shows that about 61% of IHS medical buildings are in “fair” or “poor” conditions, which severely limits medical professionals’ ability to treat their patients. Similarly, many IHS facilities report working with broken or unreliable equipment, which affects the standard of care they can provide.

Furthermore, many IHS buildings are located in remote, rural locations with few amenities like grocery stores, schools, or even adequate housing. This makes recruiting and retaining medical staff especially difficult and limits the pool of quality professionals willing to practice in their network (notably, 50-75% of physicians who contact IHS recruiters have conduct or licensure issues on their record).

 

Despite these challenges, the IHS continues to make changes that benefit AI/AN peoples across the country. For example, in 2022 the IHS fought to secure $3.5 billion in funding from the government that allowed them to improve water supplies and wastewater disposal systems on tribal lands. Efforts like these help American Indians and Alaskan Natives improve their health and enjoy a better quality of life, and they prove that organizations like the IHS offer a tremendous benefit to the people they serve.
