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.

Reviewer #1: Partly

3. Have the authors made all data underlying the findings in their manuscript fully available?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception (please refer to the Data Availability Statement in the manuscript PDF file). The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: No

Reviewer #2: Yes

**********

4. Is the manuscript presented in an intelligible fashion and written in standard English?

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: Dear authors, this manuscript tries to highlight a study but it was difficult reading it.

For example in line 69 the authors mentioned 50 Projects, but it was not explained which 50 Projects. Then in line 129 six case studies were mentioned. I lost the overview. How many patients were enrolled?

All in all I have to conclude that the manuscript is not worth for publication.

Reviewer #2: This is a well conducted mixed methods study on a very innovative style and a comprehensive approach to an increasingly relevant problem of frail people. The methodology is described well and in detail.

Revision 1

Response to reviewers

Dear reviewers and editor,

Thanks a lot for the smooth process of reviewing our article. Hereafter, you will find response to the two reviewers’ comments.

We remain, of course, ready to clarify further our work, would they be any other queries.

Warm regards,

Anne-Sophie Lambert

Reviewer #1: Dear authors, this manuscript tries to highlight a study but it was difficult reading it.

For example in line 69 the authors mentioned 50 Projects, but it was not explained which 50 Projects. Then in line 129 six case studies were mentioned. I lost the overview. How many patients were enrolled?

All in all I have to conclude that the manuscript is not worth for publication.

I would like first thank you for your pertinent comment. I totally agree with your comment. I include different elements in the paper to clarify the lines 69 and 129.

First in the introduction, I justified the number of projects (line 63 and 69). 75 projects were included in the Protocol 3 programme. Among them, 50 projects implemented Case Management. The others delivered psychological support, occupational therapy or night care. This paper focuses on the 50 projects that implemented Case Management.

Second in the methodology, I added precisions and references who justified the choice to analyze only six projects in-depth (line 113 - 125). The classification of CM projects started by the building of a normative grid: a list which captures what the stakeholders of the projects believed to be the key components of the projects [1]. To reach this objective, we used multiple embedded case study. This qualitative approach focuses on a small number of cases to highlight a causal relation assumed to be present in a large number of cases [2]. The cases are selected to extract as much diversity as possible regarding the projects‘ characteristics [2, 3]. Thus, we used six in-depth cases studies, selected among the 50 projects that implemented CM. These six projects were selected on the basis of (1) their diversity (i.e. the profile of the case manager (i.e. nurse, occupational therapist, psychologist or social worker)); (2) their geographical location (urban or rural); and (3) their collaboration with an existing organization that, among other criteria, coordinated care.

Third, in the first version of the manuscript, the number of patients enrolled was included in the S1 Appendix. However, I agree with you, it is necessary to include this information in the manuscript. So, I added the number of projects and the number of patients included in each CM category in the manuscript (lines 143, 145, 147). The total number of beneficiaries and the total number of controls were corrected (line 170). And the reference to S1 Appendix was added when I presented the number of beneficiaries per CM category (line 202, 203, 204).

Reviewer #2: This is a well conducted mixed methods study on a very innovative style and a comprehensive approach to an increasingly relevant problem of frail people. The methodology is described well and in detail.

I would like thank you a lot for your positive comment.

Reviewer #1: Dear authors, thank you for adressing all issues in the revised manuscript. I do not have any further comments.

Reviewer #2: Dear authors

You have touched upon a very complicated intervention and tried to evaluate it in the conventional method. That partly explains the complexity of the results and why it may seem very confusing. However, as you rightly mention, currently policy makers are not aware of other approaches to evaluate complex interventions. To that end your paper is very important in not ony conveying the results of the evaluation but also sending a message that newer approaches to evaluation are needed to address such interventions.

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
