Reviewer's Responses to Questions

Comments to the Author

1. Does the manuscript provide a valid rationale for the proposed study, with clearly identified and justified research questions?

The research question outlined is expected to address a valid academic problem or topic and contribute to the base of knowledge in the field.

Reviewer #1: No

Reviewer #2: Yes

Reviewer #3: Partly

**********

2. Is the protocol technically sound and planned in a manner that will lead to a meaningful outcome and allow testing the stated hypotheses?

The manuscript should describe the methods in sufficient detail to prevent undisclosed flexibility in the experimental procedure or analysis pipeline, including sufficient outcome-neutral conditions (e.g. necessary controls, absence of floor or ceiling effects) to test the proposed hypotheses and a statistical power analysis where applicable. As there may be aspects of the methodology and analysis which can only be refined once the work is undertaken, authors should outline potential assumptions and explicitly describe what aspects of the proposed analyses, if any, are exploratory.

Reviewer #1: No

Reviewer #2: Yes

Reviewer #3: Partly

**********

3. Is the methodology feasible and described in sufficient detail to allow the work to be replicable?

Descriptions of methods and materials in the protocol should be reported in sufficient detail for another researcher to reproduce all experiments and analyses. The protocol should describe the appropriate controls, sample size calculations, and replication needed to ensure that the data are robust and reproducible.

Reviewer #1: Yes

Reviewer #2: Yes

Reviewer #3: No

**********

4. Have the authors described where all data underlying the findings will be made available when the study is complete?

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception, at the time of publication. 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

Reviewer #3: Yes

**********

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

PLOS ONE does not copyedit accepted manuscripts, so the language in submitted articles must be clear, correct, and unambiguous. Any typographical or grammatical errors should be corrected at revision, so please note any specific errors here.

6. Review Comments to the Author

Please use the space provided to explain your answers to the questions above and, if applicable, provide comments about issues authors must address before this protocol can be accepted for publication. You may also include additional comments for the author, including concerns about research or publication ethics.

You may also provide optional suggestions and comments to authors that they might find helpful in planning their study.

(Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: The authors designed a Randomized Controlled Trial to measure the Effect of a Medication Coordinator on the Quality of Patients’ Medication Treatment (MEDCOOR). However, the structure of the protocol does not fit with the guideline of the journal. Several breaks between paragraphs and unnecessary underlines hinder the quality of the paper. The authors did not define or operationalize “Quality of Patients’ Medication Treatment” . Therefore, the topic and the objective that is going to be measured are not parallel. I would suggest a careful review of the protocol and its feasibility before implementation. Publication of the protocol in its current form is barely considered.

You might consider the following points to improve your work.

No Please reduce the number of keywords.

Lines 33-34“communication of communicating suggested medication amendments to the patients” should be revised.

Line 190-192, Please describe the tool.

Line 203-205, no tool validation information is included.

Reviewer #2: Dear Authors

Thank you for your submission.

The comments will be available through journal editor.

Regards

Reviewer #3: The authors describe a protocol of a study which aims to evaluate the effect of a coordinating intervention on the quality of medication treatment. The primary objective of the planned study is the proportion of potentially inappropriate medication (PIM) six months after hospital discharge.

The description is detailed in many places, other points required by the SPIRIT guideline should be further elaborated

Item 14; The sample size calculation in the manuscript is based on different assumptions and lead to a different number of patients to be includes (e.g. 93% power in the manuscript vs. 80% power in the study protocol resulting in n=70 patients per group in the manuscript or N=80 in the study protocol). Please explain deviations between the documents.

The sample size calculation based on the assumption that the expected proportions of PIMS in the intervention group is higher as in the control group. Please explain why this assumption is reasonable.

Item 15; Please add to the description of the clinic's resources which strategies will be used for achieving adequate participant enrolment to reach target sample size.

Item 16a of the SPIRIT checklist suggests keeping details of any planned restriction (eg, blocking) in a separate document to conceal this knowledge to those who enrol participants or assign interventions. So the information from line 273 ff “A simple block randomization method …” should be transferred to a statistical analysis plan.

Item 16b; Not knowing the block length alone cannot avoid predictability. Further measures to enable concealment should be considered and described in the protocol.

Item 16c; Details of the Implementation of the allocation list should be provided. Who will generate the randomization list with REDCap, who will enrol patients and who will assign participants to interventions?

Item 20a; In general, the primary hypothesis, the sample size calculation and the statistical analysis should follow the same statistical approach. That means, if the primary objective is the comparison of the proportion of potentially inappropriate medication (PIM) six months after hospital discharge between the two treatment groups, the sample size calculation as well as the primary analysis should be based on the comparison of PIMs at month six. If other timepoint are considered as co-primary endpoints or as secondary endpoints should be decided and described. In the first case, a suitable multiple testing strategy should be considered. This strategy should then also be presented in detail! The likelihood ratio test across all time point does not prove the primary hypothesis. In addition, the sample size calculation should also focus on the contrast of the described model which address the comparison of PIMs at month six.

Moreover, some of the reads may be not familiar to the beta-regression approach. I would suggest explaining the concept with sufficient information to allow the analysis to be reproduced.

Item 20b; The authors stated that no additional analyses are planned (20b n.a.) could you please outline which data will be analyzed by t-, Wilcoxon-, Fisher-, Chi-square- or log-rank- (Kaplan-Meier estimates) test.

Moreover, some minor issues are to be noted;

The name of the intervention programme is used inconsistently, Please indicate the correct name MEDCORR or My Medication plan and please adjust throughout the protocol.

The sentence on line 102 “The enrolment, intervention and assessment” is incomplete, please complete

Figure 1 in line 126 should be labeled as Figure 2.

Reviewer #2: Dear Authors

Thank you for revising the manuscript.

I hope the best outcome from this study that will be helpful for healthcare.

Best wishes

Reviewer #3: Thank you for the revised manuscript and the explanations. For me, some points remain open;

The authors clarified that the main author of the manuscript will assign, screen and recruit the patients. This approach is associated with a high potential for bias. The more important it is to take appropriate measures to avoid influencing the allocation. In particular, appropriate concelament measures should be implemented. Please note that concealment should not be confused with blinding. Concealment describes the non-disclosure of the assignment until the assignment itself, while blinding means the non-disclosure of the assignment beyond the assignment. Blinding of the statistician is not suitable to ensure concealment.

The primary outcome is (re-)defined as (p. 9, line 206-207) “... the proportion of PIMs after hospital discharge. The PIMs are defined by four different screening tools.” Furthermore, the authors stated “As a consequence of your comment, We have decided that treatment effect should be evaluated across all time points, hence we evaluated that multiple testing is not necessary.” Nevertheless, it is still to be read (p- 12, line 310-311) that “To avoid inflating the type I error rate in the z-test, we will adjust the z-test for multiple tests.” Please clarify, which timepoint are actually included (In figure 1 it is indicated that PIMs are evaluated at t1, t2 and t6 – are this baseline, 3 and 6 months?), how the primary outcome is precisely defined (as change from baseline to any timepoint after discharge or value at any timepoint after discharge), and if adjusting the significance level for multiple testing will be an issue or not. In this context, it is equally important to make clear how the four different screening tools for defining PIMs will be applied and combined.

In response to my question as to what the various tests mentioned are used for, the authors stated “We have now emphasized in the manuscript that the baseline variables will be analyzed using the above mentioned statistical tests and no additional analysis as described in the protocol will be conducted. “One of the recommendations of the CONSORT statement is that a table is presented showing baseline demographic and clinical characteristics for each group. Importantly, according to this recommendation in the CONSORT statement, “significance testing of baseline differences in randomized controlled trials (RCTs) should not be performed, because it is superfluous and can mislead investigators and their readers” (c.f. de Boer et al. International Journal of Behavioral Nutrition and Physical Activity (2015) 12:4).
