5. Recognizing Post-Endoscopy Complications: A Database Filter Reduces Quality Assurance Workload for Inpatients

Author

Abstract

Background and Aims: Documentation of complications of gastrointestinal endoscopy within the commonly used endoscopy documentation systems are mostly limited to acute complications during endoscopy included in the post-procedural endoscopy report. We tested a documentation system-based filter to reduce the workload by maintaining a high sensitivity to recognize post-endoscopy complications. Methods: Of all inpatient endoscopic resections during 1 year and all endoscopic retrograde cholangiopancreatography (ERCP) procedures during 4 months in 1 tertiary referral centre, post-procedural complications during hospital stay were individually analyzed retrospectively from the hospital databases (gold standard). In comparison, information technology-based filters were assessed searching for specific tests and data within 2 days after endoscopy and/or until discharge. These were second endoscopy, surgery, or an abdominal computed tomography (CT) or haemoglobin drop ≥2 g/dL for endoscopic resection. For ERCP cases, any case with lipase determination and post-ERCP CT scan was selected. Main outcomes were the sensitivity of these filters to recognize post-endoscopy complications and the percentage of workload reduction. Results: Three hundred twenty-two inpatients who underwent endoscopic resections and 302 ERCP cases (all inpatients) were included. Post-endoscopy complications occurred in 7.14% (endoscopic resection) and 3.7% (ERCP). The above-mentioned filters identified 100% of all resection and post-ERCP complications compared to detailed case file analysis, at the same time reducing the quality management workload to 14 and 31%, respectively. Conclusions: Post-procedural monitoring of advanced endoscopic procedures performed on inpatient procedures has a high sensitivity (100%) and reduces case-by-case screening workload for complications by 70-85%. Outpatient interventions, however, require a different system for monitoring of post-endoscopy complications after discharge

Abstract

Contains fulltext : 195662.pdf (Publisher’s version ) (Open Access), BACKGROUND AND AIMS: Numerous randomized studies have shown that changing certain features of colonoscopes, usually incorporated when switching from one endoscope generation to the next, mostly do not increase adenoma yield. There is, however, indirect evidence that it may be necessary to skip one instrument generation (ie, changing from one generation to the next but one) to achieve this effect. METHODS: We compared the latest-generation colonoscopes from one company (Olympus Exera III, 190-C) with the next to last one (Olympus 160/5-C) in a prospective multicenter study randomized for the order of colonoscopes in a tandem fashion, involving 2 different examiners. Patients with increased risk for colorectal neoplasia undergoing colonoscopy (positive fecal occult blood test, personal/familial history of colorectal cancer/adenoma, rectal bleeding, recent change in bowel movements) were included. The primary outcome was the adenoma miss rate with the 190 (190-C) colonoscope in comparison with the 160/5 colonoscope (160/5-C). RESULTS: A total of 856 patients (48.8% male; mean age, 58.3 years) with a personal (41%) or family (38%) history of colorectal neoplasia, rectal bleeding (19%), and other indications were included. Of the 429 patients in the 190-C first group, 16.6% (95% confidence interval [CI], 13.0%-20.1%) had at least one adenoma missed during the first procedure, compared with 30.2% (95% CI, 25.9%-34.6%) in the group with 160/5-C first (P < .001). Similarly, the adenoma detection rate during the first colonoscopy was 43.8% versus 36.5% (P = .030) for 190-C versus 160/5-C, respectively. CONCLUSIONS: This randomized tandem trial showed lower adenoma miss rates and higher adenoma detection rates for the newer 190 colonoscopes compared with the 160/5 series. These results suggest that it takes multiple improvements, such as those implemented over 2 instrument generations, before an effect on adenoma (miss) rate can be observed.

Abstract

AIM To compare the aspiration needle (AN) and core biopsy needle (PC) in endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of abdominal masses. METHODS Consecutive patients referred for EUS-FNA were included in this prospective single-center trial. Each patient underwent a puncture of the lesion with both standard 22-gauge (G) AN (Echo Tip Ultra; Cook Medical, Bloomington, Indiana, United States) and the novel 22G PC (EchoTip ProCore; Cook Medical, Bloomington, Indiana, United States) in a randomized fashion; histology was attempted in the PC group only. The main study endpoint was the overall diagnostic accuracy, including the contribution of histology to the final diagnosis. Secondary outcome measures included material adequacy, number of needle passes, and complications. RESULTS Fifty six consecutive patients (29 men; mean age 68 years) with pancreatic lesions (n = 38), lymphadenopathy (n = 13), submucosal tumors (n = 4), or others lesions (n = 1) underwent EUS-FNA using both of the needles in a randomized order. AN and PC reached similar overall results for diagnostic accuracy (AN: 88.9 vs PC: 96.1, P = 0.25), specimen adequacy (AN: 96.4% vs PC: 91.1%, P = 0.38), mean number of passes (AN: 1.5 vs PC: 1.7, P = 0.14), mean cellularity score (AN: 1.7 vs PC: 1.1, P = 0.058), and complications (none). A diagnosis on the basis of histology was achieved in the PC group in 36 (64.3%) patients, and in 2 of those as the sole modality. In patients with available histology the mean cellularity score was higher for AN (AN: 1.7 vs PC: 1.0, P = 0.034); no other differences were of statistical significance. CONCLUSION Both needles achieved high overall diagnostic yields and similar performance characteristics for cytological diagnosis; histological analysis was only possible in 2/3 of cases with the new needle. © 2016 Baishideng Publishing Group Inc.
