Abstract
OBJECTIVE To evaluate gastrointestinal and cardiovascular adverse event risks associated with optical colonoscopy (OC) among Medicare outpatients who received computed tomography colonography (CTC) as their initial method of colorectal evaluation. METHODS Medicare claims were compared between 6,114 outpatients ≥ 66 years who received initial CTC and 149,202 outpatients who received initial OC between January 2007 and December 2008. OC patients were matched on county of residence and year of evaluation. Outcomes included lower gastrointestinal bleeding, gastrointestinal perforation, other gastrointestinal events and cardiovascular events resulting in an emergency department visit or hospitalization within 30 days. RESULTS Among 1,000 outpatients undergoing initial CTC, 12.4 experienced lower gastrointestinal bleeding, 0.7 perforation, 18.0 other gastrointestinal events and 45.5 cardiovascular events within 30 days. After multivariate adjustment, risks of lower gastrointestinal bleeding, other gastrointestinal events and cardiovascular events were higher with initial OC than CTC, with or without subsequent OC (OR 1.91 95CI [1.47,2.49], OR 1.35 95CI [1.07,1.69] and OR 1.38 95CI [1.18,1.62], respectively); however, perforation risk did not differ (p=0.10). This pattern is similar in older and symptomatic populations. CONCLUSION Rates of gastrointestinal bleeding, other gastrointestinal events and cardiovascular events are lower following initial CTC than OC, but rates of perforation do not differ.

Abstract
BACKGROUND As a measure of quality, ambulatory surgery centers have begun reporting rates of hospital transfer at discharge. This process, however, may underestimate the acute care needs of patients after care. We conducted this study to determine rates and evaluate variation in hospital transfer and hospital-based, acute care within 7 days among patients discharged from ambulatory surgery centers. METHODS Using data from the Healthcare Cost and Utilization Project, we identified adult patients who underwent a medical or operative procedure between July 2008 and September 2009 at ambulatory surgery centers in California, Florida, and Nebraska. The primary outcomes were hospital transfer at the time of discharge and hospital-based, acute care (emergency department visits or hospital admissions) within 7-days expressed as the rate per 1,000 discharges. At the ambulatory surgery center level, rates were adjusted for age, sex, and procedure-mix. RESULTS We studied 3,821,670 patients treated at 1,295 ambulatory surgery centers. At discharge, the hospital transfer rate was 1.1 per 1,000 discharges (95% confidence interval 1.1-1.1). Among patients discharged home, the hospital-based, acute care rate was 31.8 per 1,000 discharges (95% confidence interval 31.6-32.0). Across ambulatory surgery centers, there was little variation in adjusted hospital transfer rates (median = 1.0/1,000 discharges [25th-75th percentile = 1.0-2.0]), whereas substantial variation existed in adjusted, hospital-based, acute care rates (28.0/1,000 [21.0-39.0]). CONCLUSION Among adult patients undergoing ambulatory care at surgery centers, hospital transfer at time of discharge from the ambulatory care center is a rare event. In contrast, the rate of need for hospital-based, acute care in the first week afterwards is nearly 30-fold greater, varies across centers, and may be a more meaningful measure for discriminating quality.

Abstract
Colorectal cancer and precancerous adenomas disproportionately affect the elderly, necessitating the need for screening and surveillance in this group. However, screening and surveillance decisions in the elderly can be challenging. Special considerations such as comorbid medical conditions, functional status, and cognitive ability play a role in one's decisions regarding the utility of screening and surveillance as well as the success and safety of various screening modalities. This article explores the evidence for screening and surveillance in the elderly, and addresses key challenges unique to this population.

Abstract
IMPORTANCE Deep sedation for endoscopic procedures has become an increasingly used option but, because of impairment in patient response, this technique also has the potential for a greater likelihood of adverse events. The incidence of these complications has not been well studied at a population level. DESIGN Population-based study. SETTING AND PARTICIPANTS Using a 5% random sample of cancer-free Medicare beneficiaries who resided in one of the regions served by a SEER (Surveillance, Epidemiology, and End Results) registry, we identified all procedural claims for outpatient colonoscopy without polypectomy from January 1, 2000, through November 30, 2009. INTERVENTION Colonoscopy without polypectomy, with or without the use of deep sedation (identified by a concurrent claim for anesthesia services). MAIN OUTCOME MEASURES The occurrence of hospitalizations for splenic rupture or trauma, colonic perforation, and aspiration pneumonia within 30 days of the colonoscopy. RESULTS We identified a total of 165 527 procedures in 100 359 patients, including 35 128 procedures with anesthesia services (21.2%). Selected postprocedure complications were documented after 284 procedures (0.17%) and included aspiration (n = 173), perforation (n = 101), and splenic injury (n = 12). (Some patients had >1 complication.) Overall complications were more common in cases with anesthesia assistance (0.22% [95% CI, 0.18%-0.27%]) than in others (0.16% [0.14%-0.18%]) (P < .001), as was aspiration (0.14% [0.11%-0.18%] vs 0.10% [0.08%-0.12%], respectively; P = .02). Frequencies of perforation and splenic injury were statistically similar. Other predictors of complications included age greater than 70 years, increasing comorbidity, and performance of the procedure in a hospital setting. In multivariate analysis, use of anesthesia services was associated with an increased complication risk (odds ratio, 1.46 [95% CI, 1.09-1.94]). CONCLUSIONS AND RELEVANCE Although the absolute risk of complications is low, the use of anesthesia services for colonoscopy is associated with a somewhat higher frequency of complications, specifically, aspiration pneumonia. The differences may result in part from uncontrolled confounding, but they may also reflect the impairment of normal patient responses with the use of deep sedation.

Gastrointest Endosc 2013; 77:419-29. [PMID: 23410698 DOI: 10.1016/j.gie.2012.10.028] [Citation(s) in RCA: 59] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2012] [Accepted: 10/29/2012] [Indexed: 02/08/2023]
Abstract
BACKGROUND The incidence of adverse events (AEs) is a crucial factor when colonoscopy is considered for mass screening, but few studies have addressed delayed and non-GI AEs. OBJECTIVES To investigate the risk of AEs requiring hospitalization after screening and nonscreening colonoscopies compared with control subjects who did not undergo colonoscopy. DESIGN Retrospective matched cohort. SETTING Statutory health insurance fund in Germany. PATIENTS A total of 33,086 individuals who underwent colonoscopy as an outpatient (8658 screening, 24,428 nonscreening) and 33,086 matched controls who did not undergo colonoscopy. INTERVENTIONS Outpatient screening and nonscreening colonoscopies. MAIN OUTCOMES MEASUREMENTS Risk of AEs (perforation, bleeding, myocardial infarction, stroke, splenic injury, and others) requiring hospitalization within 30 days after colonoscopy/index date and risk differences between the group that underwent colonoscopy and the group that did not. RESULTS The incidence of perforation was 0.8 (95% confidence interval [CI], 0.3-1.7) and 0.7 (95% CI, 0.4-1.1) per 1000 screening and nonscreening colonoscopies, respectively. Hospitalizations because of bleeding occurred in 0.5 (95% CI, 0.1-1.2) and 1.1 (95% CI, 0.8-1.7) per 1000 screening and nonscreening colonoscopies, respectively. The incidence of myocardial infarction, stroke, and other non-GI AEs was similar in colonoscopy and control groups. No splenic injury was observed. Those with AEs generally had a higher mean age and comorbidity rate than the overall study population. LIMITATIONS The analysis relies on health insurance claims data. CONCLUSIONS This study provides further evidence of the safety of colonoscopy in routine practice with regard to delayed and non-GI AEs. Hospitalizations because of the investigated AEs were uncommon or rare for both screening and nonscreening colonoscopies.

Prophylactic clip closure reduced the risk of delayed postpolypectomy hemorrhage: experience in 277 clipped large sessile or flat colorectal lesions and 247 control lesions. Gastrointest Endosc 2013; 77:401-7.

Abstract
BACKGROUND Endoscopic resection of large colorectal lesions is associated with high complication rates. OBJECTIVE To evaluate the effect of prophylactic clip closure of polypectomy sites after resection of large (≥2 cm) sessile and flat colorectal lesions. DESIGN Retrospective study. SETTING Tertiary referral center. PATIENTS AND INTERVENTIONS Patients with lesions 2 cm or larger who underwent EMR performed by using low-power coagulation current between January 2000 and February 2012. Beginning in June 2006, polypectomy sites were prophylactically closed with clips when possible. Patients had telephone follow-up at 30 days or later to track complications. MAIN OUTCOME MEASUREMENTS Delayed hemorrhage, postpolypectomy syndrome, and perforation. RESULTS There were 524 lesions 2 cm or larger in 463 patients, of which 247 (47.1%) were not clipped, 52 (9.9%) were partially clipped, and 225 (42.9%) were fully clipped. There were 31 delayed hemorrhages, 2 perforations, and 6 cases of postpolypectomy syndrome. The delayed hemorrhage rate was 9.7% in the not clipped group versus 1.8% in the fully clipped group. Multivariate analysis showed that not clipping (odds ratio [OR] 6.0; 95% CI, 2.0-18.5), location proximal to the splenic flexure (OR 2.9; 95% CI, 1.05-8.1), and polyp size (OR 1.3; 95% CI, 1.1-1.7 for each 10-mm increase in size) were associated with delayed bleeding. LIMITATION Retrospective design. CONCLUSIONS Prophylactic clipping of resection sites after endoscopic removal of large (≥2 cm) colorectal lesions using low-power coagulation current reduced the risk of delayed postpolypectomy hemorrhage. A randomized, prospective trial of clipping large polypectomy sites is warranted.

Abstract
BACKGROUND Compared with the general population, patients with a previous colorectal cancer are at higher risk for a second colorectal cancer, but detailed risk analysis by subsite is scarce. OBJECTIVE Our goal was to investigate the risk of a second cancer in relation to subsite as a basis for planning surveillance strategies. DESIGN, SETTING, AND PATIENTS This was a retrospective analysis of a prospectively designed, population-based cancer registry (The Netherlands Cancer Registry). Patients with a stage I, II, or III colorectal cancer diagnosed between 1989 and 2008 were included. MAIN OUTCOME MEASURES Cumulative incidence, standardized incidence ratio, and absolute excess risk for second primary cancers in subsites of the colon and rectum were estimated for follow-up periods of 2 to 5, 6 to 10, and more than 10 years after the index cancer in patients older than 50 years and in those aged 50 years or younger. RESULTS A total of 123,347 patients had a first invasive colorectal cancer diagnosed between 1989 and 2008. Of these, 1849 patients (1.5%) had a second colorectal lesion that was found more than 1 year after the initial cancer and diagnosed as a second primary colorectal cancer. In patients older than 50 years, the 20-year cumulative incidence for second cancers was 3.4% in the proximal colon, 1.2% in the distal colon, and 1.2% in the rectum. More than 60% of second cancers occurred within 5 years after the index cancer. The standardized incidence ratio was highest in the proximal-colon (1.9; 95% CI, 1.8-2.0), followed by the distal-colon (1.0, 95% CI, 0.9-1.1), and the rectum (0.9, 95% CI, 0.8-1.0). The corresponding absolute excess risks per 10 000 person years were 9 in the proximal colon, 0.1 in the distal colon, and 1 in the rectum. After 5 years of follow-up, elevated risk was observed only in the proximal colon. A similar risk pattern was observed in patients younger than 50 years. The absolute excess risk for a second cancer in the proximal colon increased over time. The proportion of stage III and stage IV second cancers increased from 31% during the first 5 years of follow-up to 38% after 10 years of follow-up. LIMITATIONS Limitations of this study included lack of data regarding polypectomy rates and interval of surveillance colonoscopies. CONCLUSIONS Compared with the general population, individuals with previous colorectal cancer have a higher risk for a second cancer in all subsites of the colon and rectum. Among long-term survivors older than 50 years, risk remains elevated only in the proximal colon. Further studies should be encouraged to develop a suitable surveillance method for aging, high-risk, long-term colorectal cancer survivors.

Abstract
PURPOSE OF REVIEW This review concerns quality assurance for gastrointestinal endoscopic procedures, especially colonoscopy and will emphasize research and guidelines published since January 2011. Important articles from previous years have been included for background. RECENT FINDINGS Critical lapses in endoscope processing and administration of intravenous sedation alerted us to the infection risk of endoscopy. Increases in cost of colonoscopy, evidence for overuse and studies demonstrating missed cancers have led some to question the value of endoscopy. Despite these setbacks, the National Polyp Study (NPS) consortium published their long-term follow-up of the original NPS patients and confirmed that colonoscopy with polyp removal can reduce the risk of colorectal cancer for an extended period. In this article, we will focus on ways to improve the value of outpatient colonoscopy. SUMMARY The United States national quality improvement agenda recently became organized into a more coordinated effort spearheaded by several public and private entities. They comprise the infrastructure by which performance measures are developed and implemented as accountability standards. Understanding wherein a gastroenterology (GI) practice fits into this infrastructure and learning ways we can improve our endoscopic practice is important for physicians who provide this vital service to patients. This article will provide a roadmap for developing a quality assurance program for endoscopic practice.
