A comprehensive training programme for nurse endoscopist performing flexible sigmoidoscopy in Hong Kong

Introduction of the Nurse Endoscopist Role in One Australian Health Service

In Australia, nurses performing endoscopic procedures is a recent phenomenon and is uncommon. Challenges include gastroenterologist and patient acceptance of the nurse endoscopist role. This article aims to explore Monash Health's experience with the introduction of a nurse endoscopist. A nurse endoscopist trainee undertook a comprehensive training program under the supervision of a gastroenterologist. All procedural data were collected, organizational policy and procedures were developed, and patients (n = 40) completed a telephone interview postprocedure. The nurse endoscopist trainee completed all training requirements during the 12-month program and was deemed competent for independent practice. The trainee performed 255 colonoscopies, with no complications reported. The organization successfully implemented the expanded scope of practice, established a new model of care for patients, and initiated a governance framework for this advanced practice role. Eighty percent of patients (n = 32) reported that overall, they had a very good experience with the nurse endoscopist trainee. A nurse endoscopist initiative can facilitate the expansion of endoscopy services to meet the growing need for gastroenterological procedures within the community. This pilot program has demonstrated that it is possible to integrate an advanced practice nurse role into an established endoscopy unit.

Colorectal cancer, screening and primary care: A mini literature review

Colorectal cancer (CRC) is a common health problem, representing the third most commonly diagnosed cancer worldwide and causing a significant burden in terms of morbidity and mortality, with annual deaths estimated at 700000. The western way of life, that is being rapidly adopted in many regions of the world, is a well discussed risk factor for CRC and could be targeted in terms of primary prevention. Furthermore, the relatively slow development of this cancer permits drastic reduction of incidence and mortality through secondary prevention. These facts underlie primary care physicians (PCPs) being assigned a key role in health strategies that enhance prevention and prompt diagnosis. Herein, we review the main topics of CRC in the current literature, in order to better understand its pathogenesis, risk and protective factors, as well as screening techniques. Furthermore, we discuss preventive and screening policies to combat CRC and the crucial role served by PCPs in their successful implementation. Relevant articles were identified through electronic searches of MEDLINE and through manual searches of reference lists.

The Safety of Multiple Flexible Sigmoidoscopies with Mucosal Biopsies in Healthy Clinical Trial Participants

During Phase 1 pharmacokinetic/pharmacodynamics studies, participants may undergo multiple sigmoidoscopies, with a collection of 10-20 biopsies during each procedure. This article characterizes the safety of flexible sigmoidoscopies in clinical trial participants. We determined the number of flexible sigmoidoscopies and rectal biopsies that participants underwent and analyzed the frequency, duration, and severity of flexible sigmoidoscopy-related adverse events (AEs). During the study period, 278 participants underwent 1,004 flexible sigmoidoscopies with the collection of 15,930 rectal biopsies. The average number of procedures per participant was 3.6 (median 3; range 1-25), with an average time interval between procedures of 61.8 days (median 28 days; range 1-1,159). There were no serious AEs. Sixteen AEs were related to flexible sigmoidoscopy and occurred in 16 participants, leading to an overall 1.6% (16/1,004) AE rate per procedure and 0.1% (16/15,930) AE rate per biopsy. Of the 16 AEs, 8 (50%) involved abdominal pain, diarrhea, bleeding, flatulence, and bloating, with an average duration of 4.7 days (median 1 day; range 1-28). Most (14/16) AEs were categorized as Grade 1 (mild), whereas two of the AEs were Grade 2 (moderate). No participant withdrew due to procedure-related AEs. Overall, the number of AEs caused by flexible sigmoidoscopy with multiple biopsies was low and the severity was mild, suggesting that this procedure can be safely integrated into protocols requiring repeated intestinal mucosal sampling.

Defining the role of the nurse in population-based cancer screening programs

Nurses are pivotal in cancer prevention and early detection, but the nurse's role in cancer screening programs has been described only in very general terms without specification of activities needed to develop the role. To identify the set of activities that compose the role of the cancer screening nurse, the authors of the current article performed a critical descriptive literature review to document nursing involvement in cancer screening, covering articles published from 2000-2012. A total of 726 potentially relevant studies were identified, and 22 of those were included in the review. Nurses carry out follow-up, coordinate treatment, ensure continuity throughout the process, provide up-to-date and pertinent information to facilitate patient knowledge and choice, work to ensure coordination among the various levels of care, provide ongoing training, lead research and publications concerning daily practice, and collaborate in investigation oriented toward early detection. The literature revealed that the nurse's role in cancer screening involves case management as the main activity as well as, exceptionally, carrying out diagnostic tests.

Concerns and challenges in flexible sigmoidoscopy screening

In 1992, two well-conducted case-control studies used data from two different health maintenance organizations and demonstrated a 59-79% reduction in mortality from colorectal cancer (CRC) following exposure to sigmoidoscopy. These studies highlight the possibility of reducing mortality from CRC using population-based endoscopic screening. The development of fiber optics improved the technology, and the ease of performing flexible sigmoidoscopy (FS) with widespread adoption of this screening modality. To date, FS is the only endoscopic screening modality that has been shown to reduce mortality in randomized clinical trials. This article reviews the development of sigmoidoscopy, its use in CRC screening and the current reduced role of this proven screening modality, and explores new frontiers for population-based FS screening.

Participation by experienced endoscopy nurses increases the detection rate of colon polyps during a screening colonoscopy: a multicenter, prospective, randomized study

BACKGROUND

No reported prospective, randomized study has evaluated the impact of an endoscopy nurse participating as a second observer during colonoscopy.

OBJECTIVE

To determine whether the participation of an endoscopy nurse enhanced the polyp detection rate (PDR) and adenoma detection rate (ADR) during screening colonoscopy.

DESIGN

Multicenter, prospective, randomized study.

SETTING

Academic hospitals.

PATIENTS

A total of 844 consecutive patients undergoing screening colonoscopy.

INTERVENTIONS

Single observation by colonoscopist or dual observation by colonoscopist and endoscopy nurse during colonoscope withdrawal.

MAIN OUTCOME MEASUREMENTS

PDR and ADR.

RESULTS

No significant difference in patient demographic data, adequacy of bowel preparation, or mean withdrawal time was observed between the 2 groups. In total, 1153 polyps, including 762 adenomas, were detected in 791 patients. Seven nonpolypoid, depressed neoplastic lesions (0-IIc or combined types) were only detected in the dual observation group. A multivariate analysis revealed that experienced (≥ 2 years) endoscopy nurse participation significantly increased the PDR and ADR compared with those in the single observation group by a colonoscopist alone (adjusted odds ratio [OR] 1.58 [95% CI, 1.07-2.32]; adjusted OR 1.47 [95% CI, 1.01-2.12], respectively). Additionally, the PDR was significantly higher in the dual-observation group with fellows (<500 colonoscopies) and an experienced endoscopy nurse versus that in the single observation group (adjusted OR 2.07 [95% CI, 1.15-3.74]). There was no significant benefit of experienced nurse participation in the subgroup with experienced colonoscopists.

LIMITATIONS

Absence of colonoscopist blinding.

CONCLUSIONS

Experienced endoscopy nurse participation increased the PDR and ADR during screening colonoscopy. However, the benefit of participation by experienced nurses appears to be exclusively with inexperienced colonoscopists.
