Power analyses typically depend on preliminary data, but even if you do not have preliminary data from which to calculate your needed sample size, you can consult similar studies that have been done to find a comparable effect size that you can use to estimate your optimal sample size. For example, if a power analysis suggests you need to recruit 150 participants to demonstrate significant results, but you can only recruit 20 participants, you should strongly reconsider your study design. Even if it is infeasible for your study to reach the exact sample size determined by the power analysis, you can use the power analysis to consider whether your study design is even plausible. Perhaps the strongest justification for sample size arises from conducting a statistical power analysis, and Intuitive Foundation generally favors proposals that include a power analysis. Similarly, stating that “all residents will be invited to participate” is insufficient. Stating that “we will recruit as many participants as possible from our institution” is insufficient. State your sample size and justify this selection. Stating that “the data will be analyzed to identify communication patterns” is insufficient. You would also need to describe your methodology for transcribing, coding, or otherwise analyzing the team’s communication data. For example, if you plan to study how surgeon gender is associated with communication in the operating room during robotic-assisted procedures, you would ideally have a way of collecting intraoperative data directly from all surgical team members. Clearly state the study endpoint(s) as well as the rationale for your chosen study design. Your data collection and analytic methods should generate data that fill the knowledge gap and allow you to test your hypothesis. HypothesisĮxplicitly state your hypothesis, which should address the knowledge gap you identified in the Description of the Problem section as well as your proposed methods. This section should justify why your research is important as well as demonstrate that it has not been sufficiently addressed by other researchers. Make sure you address relevant literature and use that knowledge to describe what gap you will be filling with your proposed research. If your project were successful, what new insights would it provide beyond your local institution? If you are proposing a new technique or process, is it something that other institutions can easily adopt? Description of Problem/Background Provide an overview of why your research is compelling and how it contributes to the broader surgical community. It is more important to be clear and concrete, relating to the topic of your research, than it is to be creative. Below are tips specific to each section of the LOI. Submissions that only refer the reviewer to an attached document may be returned to the author without review. propose research that is not feasible within the given time (1 year) and resources available ($60,000).īe sure you fill out each section of the online application.present an experimental design lacking adequate statistical power to answer the questions posed, and.do not have the relevant expertise on the project team to conduct the proposed research,.It may help to consider the most common pitfalls. Successful LOI will address one of the Intuitive Foundation priority areas. This includes the scope of the research, the expertise of the team, and institutional support. It will also establish the feasibility of the research. This can often be done by summarizing the current literature, identifying a gap in that literature, and explaining how your research will fill that gap. A successful Letter of Intent (LOI) will create a compelling argument for why the proposed research is important and novel. Thus, the highest priority letters will be those that address novel, important questions in a methodologically sound, feasible manner. The Intuitive Foundation is committed to funding high quality research that will advance understanding related to robotic-assisted surgical procedures.
