Reviewer's report:
This paper describes an inpatient quality improvement project to enhance
inpatient bowel preparation. The authors have made significant improvement in
the manuscript and it more clearly reads like a health systems science piece of
scholarship. The reviewer appreciates the thought and attention to the issues
raised in the initial review. Some minor comments below. Page 5, line 57-9: the
first part of the statement and the second part do not seem to connect or are two
disconnect thoughts. Please revise. Pg 7, line 19: standardizing should be change
to standardize. The solutions and intervention section is much improved and the
figures aid in the understanding of the work. Pg 10, line 50-51: The sentence "for
example" is incomplete and likely relates to the prior sentence. Please revise. Pg
12 line 56-Pg 13 line 6: this could be moved up into the methods section. Table 3
is an excellent value added item to the paper. Overall the manuscript is
significantly improved and will be a wonderful addition to the literature.
