What Is Known
The synthesis completed in the previous module reached two conclusions of different strength. When teams debrief in a structured way after an arrest, the resuscitations they deliver afterward are of better quality, and patients probably regain a pulse more often, a conclusion supported by a meta-analysis and by an adult study using defibrillator-recorded data (Couper et al., 2013; Edelson et al., 2008). Its effect on survival to discharge is uncertain: the pooled analysis and the adult study found none, while a pediatric intensive care study of immediate interdisciplinary debriefing found signs of improved survival and significantly more children surviving with favorable neurologic outcome (Wolfe et al., 2014).
A gap statement has to be built from that synthesis rather than from a general sense that more research is needed. Almost every clinical question could use more research. A useful gap statement names exactly which combination of population, intervention, outcome and setting the existing studies have not examined, so that the next study cannot be mistaken for a repeat of an old one.
The Gap in Four Dimensions
The first dimension is population and setting. The studies that found signs of a survival benefit were conducted in a pediatric intensive care unit, and the adult evidence comes largely from academic centers with resident-led teams and debriefing sessions for physicians. Most in-hospital cardiac arrests in a community hospital occur on adult general medical-surgical wards, where the first responders are nurses, the team assembles differently for each event and resuscitation happens less often than in an intensive care unit. No included study examined debriefing in that setting.
The second dimension concerns how and when the debriefing happens. In the adult evidence, teams met once a week to go over the arrests of the week before. Twigg (2020) distinguishes immediate or hot debriefing, held shortly after an event with the team that was present, from delayed debriefing held later with data, and notes that they serve different purposes. Immediate debriefing led by the ward's own nurses, rather than by physicians or educators, has not been evaluated for its effect on resuscitation quality in adults.
The third dimension is outcomes. The studies measured resuscitation quality and patient outcomes, but none of the included quantitative studies measured the effect of debriefing on the psychological response of the nurses involved, despite the qualitative evidence that staff value debriefing as a way to process difficult events. The fourth dimension is design. Every study of effect used a before-and-after comparison, often with a historical control, which leaves open whether improvements came from debriefing or from whatever else changed in the same months. Stated together, the gap is not debriefing in general but immediate, nurse-led debriefing on adult general wards, measured for its effects on resuscitation quality, patient outcomes and the nurses themselves, using a design that controls for time.
The Research Question
The question that follows from the gap is: among adult patients experiencing in-hospital cardiac arrest on medical-surgical wards of a community hospital (P), does immediate nurse-led structured debriefing after each resuscitation (I), compared with usual practice without structured debriefing (C), improve chest compression quality, the proportion of patients regaining circulation and the proportion discharged alive, and reduce acute psychological distress among the nurses who responded (O), over an eighteen-month period (T)?
The question is ambitious, and it is deliberately so. Its primary outcome, the one the study would be powered to detect, is resuscitation quality, measured as chest compression fraction from defibrillator recordings, because that is where the existing evidence suggests an effect is most likely and because it can be measured in every event. Survival to discharge is a secondary outcome, reported honestly but not expected to reach significance in one hospital. Nurse distress, measured with a validated brief instrument within a week of each event, is a secondary outcome that addresses the third dimension of the gap.
A Design That Fits the Gap
Randomizing individual arrests to debriefing or no debriefing would be impractical, because teams would know which arrests were debriefed and lessons would spread between them. A stepped wedge cluster design addresses both the practical problem and the design gap. Hemming et al. (2015) describe the stepped wedge cluster randomized trial as a design in which all clusters begin without the intervention and cross over to it in a random order at regular intervals, until all have received it. For a hospital with six medical-surgical wards, each ward would begin debriefing at a randomly assigned point over eighteen months, so that at any time some wards are debriefing and some are not, and changes over time can be separated from the effect of the intervention.
The design has limits that the later project would have to address. Six clusters is a small number, which limits statistical power; arrests on a single ward are infrequent, perhaps two to four a month; and nurses float between wards, carrying lessons from debriefing wards to those that have not started. These limits argue for treating the first study as a feasibility trial, measuring recruitment, fidelity of debriefing and data completeness, before a larger multisite study.
Feasibility and Ethical Considerations
Before the question becomes a study, several practical conditions would need to be met. The hospital's defibrillators would need to record compression data for every event and allow it to be downloaded, which the resuscitation committee confirmed is possible with the current devices but has never been done routinely. Each ward would need at least two nurses trained to facilitate a short structured debriefing, available on every shift, which means training about twenty nurses before the first ward crosses over. And data collection would need a coordinator with protected time, since arrests happen at any hour and records must be captured within days.
The ethical questions are real but manageable. Patient outcome data would come from existing records, so the institutional review board would need to decide whether a waiver of consent is appropriate for a minimal-risk study of a team practice. The nurse distress measure raises a different concern: staff must be free to decline the questionnaire and the debriefing itself without consequence, and any nurse who reports high distress must be offered support through the employee assistance program. A study intended to help nurses process difficult events must not become one more source of pressure on them. The feasibility phase exists to discover which of these conditions the hospital can actually meet before it commits to a larger trial.
Conclusion
The body of debriefing research supports its use to improve resuscitation quality and leaves its effect on survival uncertain. The gap is specific: immediate, nurse-led debriefing on adult general wards has not been studied for its effects on resuscitation quality, patient outcomes or the nurses involved, and no study of effect has used a design that controls for change over time. A stepped wedge study across a community hospital's wards could address each part of that gap, beginning with a feasibility phase. A gap statement built this way points to a study that would add something the existing evidence does not already contain.

How this NUR 5023 Module 6 example is structured
NUR 5023 Module 6 frequently finishes at the gap statement and the question a later project would answer; your classroom's instructions decide whether a full proposal or a focused statement is expected. This example summarizes what is known in one paragraph, then states the gap in four specific dimensions: population, form of debriefing, outcomes and setting. The gap leads to a single research question in PICOT form, a design matched to the question and the setting, and the outcomes and feasibility considerations that would decide whether the project can be done. The order follows the logic of a proposal: known, unknown, question, method.
NUR5023 Module 6 questions, answered
What does NUR5023 Module 6 usually ask for?
NUR5023 Module 6 frequently ends the course with a gap statement drawn from the student's synthesis and a research or project question that would address it. Some sections also ask for a proposed design. Your classroom's instructions decide whether a full proposal or a focused statement is expected.
How do I write a specific gap statement?
Compare what the existing studies examined with what your question needs, dimension by dimension: population, setting, form of the intervention, outcomes and design. The gap is the combination that no study has examined. Avoid general statements such as more research is needed, which apply to almost any topic.
Should the research question include every outcome of interest?
It can, but name one primary outcome that the study is designed to detect and treat the others as secondary. The primary outcome should be one that occurs often enough and is likely enough to change that a study in your setting could realistically show an effect.
