What this page is doingThe title names the intervention, the population and the outcome, which are the three elements of the question that decide which findings can be grouped together. A synthesis brief is organized by claim, and those claims only make sense against a fixed question.

Evidence Synthesis Brief: Early Mobilization of Mechanically Ventilated Adults and Functional Recovery

Question

In adults receiving mechanical ventilation in the intensive care unit (P), does early active mobilization delivered by physical and occupational therapists or nurses (I), compared with usual care, including later or less intensive rehabilitation (C), improve functional recovery at hospital discharge and in the months after (O)? The brief was prepared for a 20-bed medical ICU considering whether to adopt a protocol that begins mobilization within the first days of ventilation for eligible patients.

What Several Studies Support Together

Early rehabilitation in the ICU is feasible and can be delivered to ventilated patients, including patients receiving vasoactive support or sedation interruption, when a trained team screens daily for safety. All three trials in this brief delivered active mobilization to ventilated adults, including sitting at the edge of the bed, standing, and walking (Schweickert et al., 2009; Morris et al., 2016; TEAM Study Investigators and the ANZICS Clinical Trials Group, 2022). The claim that mobilization of ventilated patients is possible at all is therefore well supported.

The evidence also agrees that early mobilization does not shorten hospital length of stay. Morris et al. (2016), in a trial of 300 patients with acute respiratory failure that delivered standardized rehabilitation daily, found no difference in hospital length of stay, the primary outcome. The TEAM trial likewise found no increase in days alive and out of hospital at 180 days.

What Only One Study Supports

The strongest evidence of functional benefit comes from a single trial. Schweickert et al. (2009) randomized 104 sedated, ventilated adults in two academic medical centers to early physical and occupational therapy, coordinated with daily sedation interruption, or to usual care. At hospital discharge, 59% of the intervention group had returned to independent function, compared with 35% of controls, and the intervention group had fewer days of delirium. This result is often cited as though it were settled. It comes from one small trial, in two academic centers, with a mobilization team working alongside a sedation-interruption protocol, and the specific combination may matter as much as the mobilization itself.

Where the Studies Disagree, and Why

The TEAM trial, the largest in this set, randomized 750 ventilated adults in 49 ICUs in six countries to early active mobilization at the highest safe level each day or to usual care. It found no improvement in days alive and out of hospital at 180 days and found more adverse events, such as arrhythmias and changes in blood pressure, in the intervention group (TEAM Study Investigators and the ANZICS Clinical Trials Group, 2022). This finding directly conflicts with the functional benefit reported by Schweickert et al. (2009).

Three differences are likely to explain the disagreement. First, usual care: in the newer trial, usual care in many participating ICUs already included substantial mobilization, so the difference between groups was smaller than in 2009, when immobility was the norm. Second, the outcome: the earlier trial measured function at discharge, while the newer one measured survival and time out of hospital at six months, which may not capture functional gains. Third, dose and timing: the newer protocol aimed for the highest possible activity level from the start, which may have increased adverse events without adding benefit for the sickest patients. Morris et al. (2016) sits between the two: no difference in its primary outcome, but modest improvements in physical function and health status measures at six months, suggesting benefits that are real but smaller than the first trial implied.

What this page is doingDisagreement is handled openly, with the likely reasons named: usual care, outcome measure and dose. Dropping the study that disagrees costs more than including it, because a grader who reads the same literature will notice the absence.

Strength of the Evidence

The evidence for feasibility and safety with a structured screening protocol is moderate to strong. The evidence that early mobilization improves long-term survival or reduces length of stay is weak, and the largest trial points against it. The evidence that it improves function at hospital discharge rests mainly on one small trial and is low to moderate. The evidence that very intensive mobilization from the first day is harmful in some patients is moderate, from the largest trial.

Actionable Statement and Its Boundaries

For the medical ICU considering a protocol, the evidence supports this statement: offer early, progressive mobilization to ventilated adults who pass a daily safety screen, coordinated with sedation minimization, with activity increased gradually rather than to the highest level from the start, and with monitoring for arrhythmia and blood pressure changes during sessions. This statement applies to adults in medical ICUs similar to those studied. It does not support promising the unit's leadership a shorter length of stay, and it does not support the most aggressive protocol tested. The unit should measure function at discharge, adverse events during sessions, and delirium days, which are the outcomes the evidence suggests are most likely to change.

What this page is doingThe brief is organized by claim rather than by study, carries a strength statement for each claim, and lands on one actionable statement with its population and limits attached. A recommendation larger than the evidence, such as promising shorter stays, is the second most expensive failure in this deliverable.

What the NU 700 Unit 7 instructions ask for

The Unit 7 assignment asks you to synthesize the evidence you have gathered into a brief that answers your clinical question and supports, or does not support, a practice change. Expect to restate the question, then organize findings by what they show rather than by study. Many versions ask you to rate the overall strength of the evidence and to write a recommendation that a unit could act on. Some ask for implementation considerations or barriers. The brief is usually shorter than earlier papers, so the instructions may set a tight word or page limit. Use the studies already appraised in earlier units unless your section allows new sources. If the evidence does not support a change, the brief should say so; that is an acceptable conclusion.

How the NU 700 Unit 7 example is put together

The sample starts with the question in PICO form so every later claim can be traced to it. Instead of a section per trial, the brief groups findings into three levels: claims several trials support, a claim only one trial supports, and claims where trials disagree. That structure makes the strength of each conclusion visible without a separate table. The disagreement section explains the TEAM result with differences in timing, intensity and patient mix rather than calling one trial wrong. The strength section rates feasibility as moderate to strong and functional benefit as weak to moderate, with reasons. The final section gives a recommendation in one sentence, then lists its boundaries: patients who pass a safety screen, coordination with sedation breaks, and close tracking of adverse events.

Where the points sit in the NU 700 Unit 7 rubric

Herzing rubrics for a synthesis brief usually award points for the clinical question, the synthesis of findings, the evaluation of evidence strength, the recommendation, and professional writing. The synthesis criterion is weighted heavily and gives full points only when findings are integrated across studies rather than reported one study at a time. Strength of evidence earns points when it uses consistent terms and explains the rating. The recommendation criterion checks whether the action follows from the evidence, fits the setting and states its limits. Implications or next steps sometimes get their own line, especially in sections that connect this brief to a later project. The writing row covers concise organization, adherence to the length limit and APA 7 formatting of citations and references.

Common NU 700 Unit 7 mistakes, and how to avoid them

Many Unit 7 briefs lose points by summarizing each study in its own paragraph, which repeats the matrix instead of synthesizing it. Another common problem is a recommendation stronger than the evidence, such as calling for a unitwide protocol when only one trial showed functional benefit. Students also leave out the study that disagrees, which graders notice when it appeared in earlier units. Strength ratings without reasons earn little. A brief that runs well past the limit loses points for concision even when the content is good. Avoid vague recommendations like continue to monitor the literature; say what the unit should do and for whom. Finally, check that each claim cites the studies behind it, because a synthesis without citations reads as opinion.

NU 700 Unit 7 questions, answered

How is this different from the table earlier in the course?

The table shows each study separately so they can be compared. The brief argues across them and reaches one statement, which means the studies stop being the organizing principle and the findings take over. A common error is submitting the table's narrative paragraph again with a recommendation added to the end, and the synthesis criterion reads that as accumulation.

What if the evidence does not support a change?

Say so and recommend accordingly. A brief concluding that current practice should continue, or that the evidence is too thin to act on yet, is a legitimate finding and often the honest one. What loses points is forcing a recommendation the body of evidence cannot carry, then defending it with the single most favorable study in the set.

Should the brief include implementation detail?

Only as much as your instructions ask for. The piece is judged on whether the recommendation follows from the evidence, so pages about rollout tend to displace the reasoning that earns the points. Naming who the recommendation is for and what would have to be true for it to work is usually enough at this stage of the course.

How is an evidence synthesis different from a literature review?

A literature review often describes studies one after another. A synthesis groups findings by what they show and how strongly, then reaches a conclusion. This sample sorts claims into those several trials support, those one trial supports, and those where trials disagree.
