The impact of potential variation in scoring by individual endoscopists and whether a strict definition of < 6 as the definition of a poor prep is valid remains a subject of debate. This study compares the BBPS scores of individual GI endoscopists and total polyp detection with respect to defining a cutoff in a predominantly African American population (82%). Methods: Using the electronic medical records for patients undergoing screening colonoscopies we identified 132 patients with BBPS seen by 8 GI attendings (identified as A1-A8). Three categories of BBPS were used in this study: Excellent (9-7), Good (6-5) and Poor (4-3). The EMR was used to identify the number of polyps identified in each colonoscopy as well as the number of polyps per bowel segment. Results: The population was primary African American (84%), female (64% ) and the average age was 60 years. Most patients had a BBPS score of 9 (64%), while only 10% had scores between 5-3. When evaluated for the score that generated significant numbers of polyps detected, 4-3 were worse (16%) as compared to both 6-5 (80%) and 9-7 (60%). There was a modest but significant difference (p=0.02) between the BBPS scoring of the 8 Colonoscopist (Figure 1). The primary variation was the number of patients with scores of 6-5. When total polyps detected and BBPS were evaluated, there was no correlation between the BBPS scores and the number of polyps detected per colonoscopy (Figure 1 and 2). This was also true when expressed as polyp detection ratio (i.e. colonoscopies with at least 1 polyp). When polyp location was identified by each of the five areas (cecal, ascending, transverse, descending, sigmoid or rectum), the only significant variability between the individual gastroenterologists and detection of polyps was the descending colon (p=0.002). Discussion: This study demonstrates potential variation between the scoring of patient bowel preparations by gastroenterologists using the Boston Bowel Prep Score especially in the intermediate area (5-9). There was however no correlation between the scores and the detection of polyps. While our data confirms that very poor bowel preparation (3-4) results in lower polyp detection, it does suggest that it may be difficult to define a rigid cutoff for BBPS as < 6 aa compared to a more rigorous score of < 5.
Figure: Figure 1 Boston Bowel Preparation Score is presented for each of 8 Colonoscopists. The three categories are Excellent (7-9), Good (5-6) or Poor (3-4). The variation is significant a p<0.05
Figure: Figure 2 Polyp detection per colonoscopy is plotted for each colonoscopist (labeled A1-A8). The number of patients is below the label. There was no significant difference between the polyps per colonoscopy and there was no correlation between the polyps detected and the BPS scores as depicted in Figure 1).
