PLOS ONE

Dear Drs van der Does,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

We would appreciate receiving your revised manuscript by Feb 21 2020 11:59PM. When you are ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter.

To enhance the reproducibility of your results, we recommend that if applicable you deposit your laboratory protocols in protocols.io, where a protocol can be assigned its own identifier (DOI) such that it can be cited independently in the future. For instructions see: http://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols

Please include the following items when submitting your revised manuscript:

• A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). This letter should be uploaded as separate file and labeled 'Response to Reviewers'.
• A marked-up copy of your manuscript that highlights changes made to the original version. This file should be uploaded as separate file and labeled 'Revised Manuscript with Track Changes'.
• An unmarked version of your revised paper without tracked changes. This file should be uploaded as separate file and labeled 'Manuscript'.

Please note while forming your response, if your article is accepted, you may have the opportunity to make the peer review history publicly available. The record will include editor decision letters (with reviews) and your responses to reviewer comments. If eligible, we will contact you to opt in or out.

We look forward to receiving your revised manuscript.

Kind regards,

Reviewer's Responses to Questions

Comments to the Author

1. Is the manuscript technically sound, and do the data support the conclusions?

The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. Experiments must have been conducted rigorously, with appropriate controls, replication, and sample sizes. The conclusions must be drawn appropriately based on the data presented.

If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: This was a well designed and presented study. The study was appropriately powered and the statistical analysis was appropriate.

My one concern about the study design was with the Causation and preventability tool, (Table S3). This was the tool used to determine inclusion into the study and was based on subjective assessments of prior hospital care and was scored by the discharging team. Thus this leaves the possibility of underscoring patients who might otherwise meet criteria and thus artificially lowering the percentage of PPR. This should be addressed in the discussion.

Reviewer #2: Dear Authors, it is a very nice design, but I would prefer that this project is either stratified based on specialty or you could split the project into 2 or 3 papers based on the different specialities. Reasons of readmission would be different in surgery from medicine. So putting both in one basket, would affect your results. I would rather put cardiology, gastroenterology, internal medicine, neurology, pulmonology in one group and general surgery in a separate group. Psychiatry also would have different group by itself.
