Risk factors for suboptimal bowel preparation for colonoscopy in pediatric patients.
Suboptimal bowel cleansing is common in children and can impact diagnostic and therapeutic outcomes. In this retrospective study, the investigators aimed to identify risk factors for suboptimal bowel preparation for colonoscopy in pediatric patients. The investigators concluded that Medicaid status and English as a second language were risk factors. They highlighted distinct associations from those reported in the adult literature including failure to thrive and younger age.

Inequitable access to surveillance colonoscopy among Medicare beneficiaries with surgically resected colorectal cancer.
After colorectal cancer (CRC) surgery, surveillance with colonoscopy is an important step for the early detection of local recurrence. Unfortunately, surveillance colonoscopy is underused, especially among racial/ethnic minorities. This study assessed the association between patient and neighborhood factors and receipt of surveillance colonoscopy. The investigators concluded that receipt of initial surveillance colonoscopy remained low, and that there were acute disparities between Black and NHW patients.

Variation in colectomy rates for benign polyp and colorectal cancer.
Removal of pre-cancerous polyps on screening colonoscopy is a mainstay of colorectal cancer (CRC) prevention. Complex polyps may require surgical removal with colectomy, an operation with a 17% morbidity and 1.5% mortality rate. Recently, advanced endoscopic techniques have allowed some patients with complex polyps to avoid the morbidity of colectomy. In this study, the investigators compared regional variation in colectomy rates for CRC versus benign polyp.

Association between primary care visits and colorectal cancer screening outcomes in the era of population health outreach.
The researchers assessed associations between primary care provider (PCP) visits and receipt of colorectal cancer (CRC) screening and colonoscopy after a positive fecal immunochemical (FIT) or fecal occult blood test (FOBT). They found that patients with a greater number of PCP visits had higher rates of both incident CRC screening and colonoscopy after positive FIT/FOBT, even in health systems with active population health outreach programs.

Colonoscopy and risk of infective endocarditis in the elderly.
The authors estimated the risk of infective endocarditis (IE) after colonoscopy in individuals aged 70 to 79 without a history of colorectal cancer (CRC), endocarditis, or colectomy from a random 20% sample of Medicare beneficiaries. Their findings suggest that individuals without risk factors for IE and those without gastrointestinal symptoms did not have an elevated IE risk after colonoscopy. However, they found a modestly increased risk among individuals with risk factors for IE who undergo a polypectomy or a biopsy during a colonoscopy following recent symptoms.

Diagnostic colonoscopy following a positive fecal occult blood test in community health center patients.
Fecal occult blood testing (FOBT) is a pragmatic screening option for many community health centers (CHCs), but FOBT screening programs will not reduce mortality if patients with positive results do not undergo diagnostic colonoscopy (DC). This study was conducted to investigate DC completion among CHC patients. It found that DC completion was low overall, which raises concerns about whether FOBT can reduce CRC mortality in practice.

Risks associated with anesthesia services during colonoscopy.
The researchers aimed to quantify the difference in complications from colonoscopy with vs without anesthesia services. They concluded that the overall risk of complications after colonoscopy increases when individuals receive anesthesia services. The widespread adoption of anesthesia services with colonoscopy should be considered within the context of all potential risks.

Delays in surgery for patients with coronary stents placed after diagnosis of colorectal cancer.
The researchers sought to determine whether the presence of a coronary stent affected the timing of colorectal cancer resection and the postoperative outcomes. They found that the median time from diagnosis to surgery was 100 days for patients who received a stent after a colonoscopy and 42 days for patients whose stent was present at the time of the colonoscopy.

Have screening harms become newsworthy? News coverage of prostate and colorectal cancer screening since the 2008 USPSTF recommendation changes.
The researchers aimed to determine whether newspapers portrayed screening for prostate and colorectal cancers differently after the 2008 USPSTF recommendation changes. In US newspapers from 2005 to 2012, they found that benefits in prostate cancer screening articles and harms and benefits in colonoscopy articles did not change over time, but mentions of prostate cancer screening harms increased after 2008. They concluded that consumers, especially lay consumers, are receiving unbalanced information on cancer screening.

Patterns of colorectal cancer screening uptake in newly eligible men and women.
The researchers describe patterns of colorectal cancer screening uptake in a U.S. insured population as individuals become newly eligible for screening at age 50 and assess temporal trends and patient characteristics with screening uptake. Their results suggest that characteristics of newly eligible individuals who initiate colorectal cancer screening are similar to the characteristics of all U.S. adults who receive colorectal cancer screening tests.
