The topic, an overview of systematic reviews on effects of deprescribing interventions in older adults, is interesting. Please see my comments below. Major revision This is an important topic, but the focus is very broad and the manuscript did not sufficiently take into account the complexly of the field. A large number of different intervention approaches have been evaluated for deprescribing medications in older adults, but the paper does not distinguish between the different types of intervention. Although it is mentioned that “we synthesized results according to the focus of the intervention (i.e., deprescribing specific medication targets, or general deprescribing)” (line 111), this was done as a subgroup analysis and did not really address different types of interventions. The focus on outcomes irrespective of the intervention approach seems too simple to draw clinically relevant conclusions. The methodological quality of the reviews and the certainty of evidence were also not taken into account in the analysis and the interpretation of the results. All except one of the included reviews had an AMSTAR 2 rating of low or critically low. Methodological guidance on conducting systematic reviews of complex interventions was also not incorporated in this review (e.g. Guise JM et al. 2017. AHRQ series on complex intervention systematic reviews-paper 1: an introduction to a series of articles that provide guidance and tools for reviews of complex interventions. J Clin Epidemiol 2017;90:6-10. doi: 10.1016/j.jclinepi.2017.06.011). Therefore, the main conclusion “Deprescribing interventions likely resulted in medication reduction” seems not appropriate. Detailed comments Abstract Please specify the objective. I recommend avoiding the term “effectiveness”, since the manuscript do not clearly distinguish between studies evaluating efficacy and effectiveness. The term “effects” seems to fit better. Methods - “We included randomized or non-randomized controlled designs.” Please revise the sentence, since reviews and not primary studies were included. Introduction Although some approaches for deprescribing interventions in older adults are mentioned, detailed information are lacking. Different intervention approaches use different mechanisms to change prescribing practice. A subgroups analysis based on intervention type is mentioned in the introduction, but not presented in detail in the manuscript. No rational for this unspecific review question is presented. Methods The methods seem appropriate with exception of the analysis and synthesis (see my general comment above). However, such an intervention-centred approach seems crucial for such an overview of complex interventions. Line 157: “(…) their GRADE [24] assessment of study quality (…)”: GRADE us used to assess the quality or certainty of the evidence on a specific outcome rather than the study quality. Please revise. Data synthesis Please describe in detail how “beneficial effects” were defined, e.g. based on effect estimates or confidence intervals (CI)? Was the precision of the results considered and the quality/certainty of evidence for the respective outcome? If quality/certainty of evidence was considered, how about reviews that did not use the GRADE approach? Please describe in more detail who was part of the expert panel (including information of methods to handle conflicts of interests) and how the expert panel contributed to the review? Was a consensus process used or similar approaches? Results As mentioned above, the summary of the results is too superficial and lacks details about the intervention approaches, intervention details (e.g. components) and detailed information about the study results, certainty of evidence and the methodological quality of the reviews. The information on the different intervention types (line 363 and following) does not report sufficient details about the intervention approaches. Reviewer #2: anuscript ID: PONE-D-23-42998 Effectiveness of Deprescribing Interventions in Older Adults: An Overview of Systematic Reviews The authors have synthesized evidence from reviews to provide an overarching overview of effectiveness of Deprescribing interventions in older adults. This is a valuable piece of work and appreciate the authors’ effort. Some of my comments are as follows: 1. Introduction – L83: The authors state that earlier work focused on reducing polypharmacy by addressing the appropriateness of medications and discontinuing those where harms outweigh benefits. As a reader, I would want to look into some of these studies. The authors can highlight these studies providing reference(s). 2. Method – Search strategy - L120: The term information specialist might not be a common word in some parts of the world. It might be worth defining it or providing alternative word in a bracket such as ‘librarian’ for wider audience. 3. Method – Table 1 – Population: I appreciate that the authors have considered studies conducted in long-term care even if age was not provided. My comment is related to the definition of population. The authors have considered aged 60 years and above as older adults. However, the authors have used search term ‘Aged’ and ‘older adults’ in their search strategy, which are considered as electronic databases as person 65 years and above. Often studies on older adults have considered the later definition. So, it would be great if the authors could clarify this. 4. Method - Expert panel: The authors have considered an interprofessional expert panel for providing input in this review. I understand that they had a broad range of clinical and perspective related to the care of older adults. But for the methodological rigor the reader would benefit from knowing about the specific criteria for their inclusion. 5. Result – Step 2 (page 12, L276): The author state there were 19 studies reporting on mortality but have cited only 18 studies. 6. Discussion – please consider the grammar – L384: “…and those that did found…” 7. Discussion: The authors have raised a really good point that majority of reviews did not specifically aim to examine harms. While this is true, studies reporting on the causality of harm due to deprescribing is also limited. It is also true that unless evidence of harm associated with deprescribing is well established, deprescribing option should be open to patients. This is not a comment but a view. Reviewer #3: Thank you for asking me to review this manuscript. This topic is important and timely. There are some comments below that I think should be seriously considered to ensure this overview meets current standards and provides more information to the reader. Comments: Major: a. Step 1: summarizing conclusions of reviews and meta-analyses: Although the authors have charted the review authors’ conclusions (in a supplement table), they do not perform any synthesis on the conclusions or even describe them at any length. I would suggest not considering these review conclusions as part of the overview’s synthesis and just refer to this information as charted in the appendix. b. A key step in an overview (as per Cochrane ch 5 guidance) is to collect, analyze and present the risk of bias of the included studies (usually as assessed by the review authors), and to integrate this into the overview’s synthesis. If ROB assessments are not complete or are inadequate, some overview authors will re-assess the studies themselves. The new reporting guidance for overviews (Gates et al. PRIOR) asks that if authors do not re-asses any of the primary studies (when identifying flaws) that they provide justification for this. c. The synthesis for steps 1 and 2 currently focuses on a count of reviews that had particular conclusions about the interventions, of which very few assessed the certainty of evidence (eg GRADE) to help the authors describes to what degree factors such as directness, ROB, imprecision may have impacted the conclusions. Without the ability to rely on and add the review authors’ certainty assessments, the overview authors should (if not willing to perform GRADE) add some information about these factors and consider whether any of these factors changes the conclusions. For example, 2 reviews of several large well-done RCTs that found no difference for an outcome may have had higher certainty evidence than 7 reviews with few small non-randomized studies that found beneficial effects. For both synthesis steps, adding information into the main manuscript (e.g. text for meta-analysis findings and in Table 3 for each category of magnitude for each outcome) about the number of studies, total sample size, and the study ROB (e.g. % studies with high ROB) for each review outcome would add some additional insight to the findings across the categories of effect. The reviews used for these conclusions could be cited rather than the focus of the synthesis. Further, separating the effects (and data on other factors eg sample size) by general deprescribing versus specific targets (and mentioning the targets) would be informative. Table 3 could add a lot more information to be very useful for readers. An overview would ideally provide a GRADE certainty assessment about each outcome but at least providing some additional data beyond just the number of reviews to help draw conclusions would be very useful. d. Because there was very little overlap across the reviews, it appears suitable to consider combining the results from reviews with and without meta-analysis. Results from meta-analyses can easily be categorized into the 6 categories of effect and without this added information the synthesis in step 2 appears incomplete. Step 2 could therefore combine findings across all reviews, while possibly removing reviews if their studies are in complete overlap with others reviews (especially the ones that did meta-analysis). Table 3 could be split into 2 tables if necessary; Table 2 data could likely be integrated into Table 1 easily to reduce the number of tables. e. It appears that the categories of effect size currently focus on statistical significance and this should be clearly stated or changed to “clinically important” etc) with use of some threshold of effect. Possibly for those effects that are of “no difference” the authors could highlight the ones where the point estimate appears large (eg relative risk of 2+) but just did not reach significance? There is also the possibility to conclude “beneficial effect” when the results are statistically but not apparently of clinical importance (e.g. a precise estimate RR 1.09) but if the authors choose not to do this they should at least mention this possibility and that focus on significance can be misleading. Minor comments: • Abstract: We included data in reviews from randomized or non-randomized controlled designs.- original sentence made it sound as though these studies were being included vs only review of the studies • Methods: data extraction. The screening process appeared to require 2 people to agree to progress a citation to full text, which may have led to missed studies. If there is no consensus at this stage it would better to include to full text any citation either of 2 reviewers thought should be looked at closer. This is the main reason we use 2 reviewers at this stage. Suggest to add this as a potential limitation ot the review. • p. 7 GRADE does not assess study quality but rather the certainty of the evidence across studies (for an outcome) • p.8 description of the categories of effect, I think (2) should be “both beneficial effects and no evidence of effect” • p.17 the use of review authors names and underlining contrasts with the general format of the rest of the manuscript -suggest to make this consistent ********** 6.
