Summary
Medicaid expansion (ME) increased colon cancer treatment, particularly surgery for early-stage disease and chemotherapy for young, late-stage patients. ME did not impact treatment timeliness but benefited specific demographic groups.
Area of Science:
- Oncology
- Health Services Research
- Public Health Policy
Background:
- Medicaid expansion (ME) has improved colon cancer screening rates.
- The impact of ME on colon cancer treatment patterns remains less understood.
- This study investigates ME's influence on colon cancer treatment modalities.
Purpose of the Study:
- To analyze the effect of Medicaid expansion on colon cancer treatment patterns.
- To identify specific patient subgroups benefiting from ME regarding treatment.
- To assess if ME influences the timeliness of colon cancer treatment.
Main Methods:
- Utilized the Louisiana Tumor Registry to identify patients with primary invasive colon cancer.
- Compared treatment patterns between pre-ME (2014-2015) and post-ME (2017-2018) diagnosis periods.
- Employed multivariable logistic regression to model treatment status, reporting adjusted odds ratios.
Main Results:
- Decreased uninsured rates post-ME, notably in young adults, African Americans, and high-poverty areas.
- Increased likelihood of surgery for Stage I-III colon cancer patients post-ME (OR=1.95), especially the extremely impoverished (OR=2.39).
- Young Stage IV patients showed increased chemotherapy use (OR=1.6); overall Stage IV treatment within 30 days decreased (OR=0.7), primarily in non-Medicaid patients.
Conclusions:
- Medicaid expansion is linked to increased colon cancer treatment utilization.
- ME did not negatively affect the time to treatment initiation.
- ME's impact on treatment varies across different demographic and socioeconomic subgroups.

01:29Drugs for Treatment of Ulcerative Colitis in IBD
118
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

01:29Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
141
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

01:25Endoscopic Procedures II: Colonoscopy
53
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
46
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

01:17Drugs for Treatment of Diarrhea-Predominant IBS
142
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

01:21Cancer Survival Analysis
324
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
