Searching Databases: PICO(T) Question Discussion Guide

The car analogy in the prompt is doing real work: you decide what matters before you search. Post the actual search, not a description of searching.

A clinical inquiry is not yet a question

The analogy the prompt opens with is more than decoration. You decide what matters before you start looking, because the criteria determine the search rather than the other way round. A clinical inquiry is the vague version — something you have wondered about on the unit. A PICO(T) question is that inquiry forced into components specific enough to be searched: population, intervention, comparison, outcome and, where it applies, time. The step people skip is the comparison, and it is usually the most useful one, because 'compared with usual care' or 'compared with hourly rounding' turns a topic into a question that a database can answer. The outcome has to be measurable too. Better patient satisfaction is a wish; a change in a named score, in fall rate per thousand patient days, or in thirty-day readmission is something a study can report and you can find.

Then post the search itself, because that is the part a marker can assess. Give the database you used and why it fitted — CINAHL for nursing-specific literature, PubMed or PMC for biomedical breadth, Cochrane for synthesised evidence, PsycINFO for behavioural outcomes. Give the terms you actually typed, the Boolean operators, any controlled vocabulary such as MeSH headings, the filters you applied for date and study type, and how many results each step returned. That narrowing sequence is the evidence you searched systematically rather than typed a sentence into a box. Say what you would change next time: too few results usually means the question is over-specified or the terms are too narrow, while thousands of results means a concept is missing. And note where the vocabulary differs between databases, since a term that works in CINAHL may not exist in PubMed's thesaurus at all.

Discussion Searching Databases Discussion: Searching Databases When you decide to purchase a new car, you first decide what is important to you. If mileage and dependability are the important factors, you will search for data focused more on these factors and less on color options and sound systems. The same holds true when searching for research evidence to guide your clinical inquiry and professional decisions. Developing a formula for an answerable, researchable question that addresses your need will make the search process much more effective. One such formula is the PICO(T) format. In this Discussion, you will transform a clinical inquiry into a searchable question in PICO(T) format, so you can search the electronic databases more effectively and efficiently. You will share this PICO(T) question and examine strategies you might use to increase the rigor and effectiveness of a database search on your PICO(T) question. To Prepare: Review the Resources and identify a clinical issue of interest that can form the basis of a clinical inquiry. Review the materials offering guidance on using databases, performing keyword searches, and developing PICO(T) questions provided in the Resources. Based on the clinical issue of interest and using keywords related to the clinical issue of interest, search at least two different databases in the Walden Library to identify at least four relevant peer-reviewed articles related to your clinical issue of interest. You should not be using systematic reviews for this assignment, select original research articles. Review the Resources for guidance and develop a PICO(T) question of interest to you for further study. It is suggested that an Intervention-type PICOT question be developed as these seem to work best for this course. By Day 3 of Week 4 Post a brief description of your clinical issue of interest. This clinical issue will remain the same for the entire course and will be the basis for the development of your PICOT question. Describe your search results in terms of the number of articles returned on original research and how this changed as you added search terms using your Boolean operators. Finally, explain strategies you might make to increase the rigor and effectiveness of a database search on your PICO(T) question. Be specific and provide examples. By Day 6 of Week 4 Respond to at least two of your colleagues on two different days and provide further suggestions on how their database search might be improved. Hello Kelsie, You are correct when you say that a research question is necessary to perform an effective database search. A few years ago, I worked in a small community hospital located in a rural area in Arizona. I was promoted as Director of Nursing for the Inpatient Unit and the Emergency Department. In our Inpatient Unit, patients were admitted either Med-Surg, Tele, or ICU status. Prior to this position I was working as a Quality Manager where I was directly responsible for submitting files to the third party, we used to conduct our patient surveys. When there were patient complaints, I would speak to the patient, review the chart and conduct the research necessary to determine if the patient complaint was substantiated or unsubstantiated. Most patient complaints were all related to some type of communication error or lack of communication of some sort from medical staff to the patient. As the Director of Nursing, I identified areas where I needed to implement processes or change a process that was currently not effective. One area I concentrated on was physicians and nurses working in a more collaborative manner to improve on better communication amongst medical staff and the patient. I conducted research using the PICOT question; If physicians and nurses rounded together on patients whom are admitted on the inpatient unit, will our patient satisfaction scores improve? I used a journal I found titled, “Implementation of Physician and Nurse Patient Rounding on a 42-bed Medical Unit” and found it to be very useful. The article was helpful and had results of more than one study that was conducted on the Medical Unit. Per the Journal Article, the studies found to be that, Nurses on the unit showed increased satisfaction with their working relationships with the physicians through improved teamwork and collaboration between the two groups and the results of the unit-specific Press Ganey scores showed an increase in patient satisfaction with how staff worked together to care for them (Pritts, 2017). Press Ganey scores increased and nurse turnover decreased (Pritts, 2017). I utilize this study to develop and implement a process improvement plan. I developed a process, implemented he process, trained all staff involved and saw positive changes within a few months. Our patient satisfaction survey scores increased, the outcome was positive and our patients were happy with the care provided to them. Using the PICOT question, I chose really helped me search databases to find a great article I was able to mimic in my own organization. Pritts, K. (2017). Implementation of Physician and Nurse Patient Rounding on a 42-Bed Medical Unit. Medsurg Nursing. Pittman, New Jersey, 23, 6, 408-413, Nov. 2014. ISSN: 1092-0811.

Review before submission

Common mistakes

  • Omitting the comparison, which is what makes the question searchable.
  • Writing an outcome that cannot be measured, such as 'improved care'.
  • Describing the search in general terms instead of posting the strategy.
  • Using one database and treating its vocabulary as universal.

Submission checklist

  • Does your PICO(T) name a measurable outcome?
  • Is the comparison stated, even if it is usual care?
  • Have you posted the actual terms and operators?
  • Did you report result counts and what you would change?
