Evidence Appraisal: Five Hip Fracture Trials of Structured Delirium Prevention

Inclusion Rule

This appraisal weighs the controlled studies from my search that meet four conditions: participants were older adults having surgery for hip fracture; the intervention was a structured, multicomponent, nonpharmacologic prevention program; a concurrent control group received usual care; and delirium incidence was measured with a standardized method. Five studies qualify. Systematic reviews are set aside here and used later for context, and single-component studies, such as music trials, are excluded by the rule.

Study by Study

Marcantonio et al. (2001). Design: single-center randomized trial with daily blinded delirium assessment using the Confusion Assessment Method. Sample: 126 patients aged 65 and older, admitted emergently, mean age 79. Effect: delirium in 32% with proactive geriatrics consultation against 50% with usual care, relative risk 0.64, about one case prevented for every six patients. Threats: modest sample, one academic center, and a wide confidence interval whose upper bound nearly reaches no effect. The design permits a causal claim for geriatrician-directed prevention in this population.

Lundström et al. (2007). Design: randomized trial comparing a specialized geriatric ward with a conventional orthopedic ward after surgery. Sample: 199 Swedish patients with femoral neck fractures, all at least 70 years old, mean age 82. Effect: delirium in 54.9% of intervention patients against 75.3% of controls, and half as many delirium days. Threats: the intervention bundled staff education, a different ward, and different staff, so which element mattered cannot be separated; assessors were not described as blinded. The design permits a causal claim for the whole package, not for any part.

Deschodt et al. (2012). Design: controlled trial without randomization. Sample: 171 older adults, 65 or above, from two Belgian university trauma units. Effect: delirium in 37.2% with a multidisciplinary geriatric consultation team against 53.2% with usual care; no difference in severity or duration once delirium began. Threats: allocation not random, so groups may have differed in ways that were not measured. The design supports an association more than a cause.

Watne et al. (2014). Design: randomized trial with blinded follow-up. Sample: 329 patients in Oslo randomized in the emergency department to an acute geriatric ward or an orthopedic ward. Effect: delirium in 49% against 53%, not significant; no difference in cognition at four months. Threats: randomization before surgery included patients already delirious on arrival, which leaves less incident delirium to prevent. The design is strong, and its null result has to be taken seriously.

Unal et al. (2022). Design: randomized trial registered in advance. Sample: 84 Turkish patients aged 65 and older, mean age 80.6. Effect: no delirium in the nurse-delivered protocol group against 15% with standard nursing care. Threats: small sample, assessment by staff who may have known allocation, and a low control incidence that makes the population look healthier than in the other trials. The design permits a causal claim, but the effect size is fragile: a handful of cases in either group would change it.

Where the Studies Disagree

Four studies found less delirium with structured prevention, and one did not. The Oslo trial's null result can be explained, in part, by three differences. First, timing: patients were randomized in the emergency department, and a meaningful share were delirious before surgery, while the positive trials largely measured new delirium after enrollment. Second, model: Oslo moved patients to a separate geriatric ward, and a meta-analysis of four trials found that the benefit came from teams visiting the orthopedic unit, with no significant effect where patients were moved to a geriatric ward (Shields et al., 2017). Third, baseline: control incidence in Oslo was 53%, similar to Deschodt's, so the null result is not explained by a healthy population. The explanation is partial. It is possible that the positive results partly reflect weaker designs and unblinded assessment.

The nurse-only trial disagrees in another way. Its effect, 15 percentage points to zero, is larger in relative terms than any physician-led trial, which is more likely to reflect its small size and low baseline than a superior model. Larger effects in smaller studies were also noted in a recent review of nurse-led orthopedic interventions (Kraonual et al., 2026).

Confidence

For older adults after hip fracture, the body of evidence supports moderate confidence that structured multicomponent prevention directed by a geriatric team and delivered largely by nurses on the orthopedic unit reduces delirium incidence, by roughly a third in relative terms. Confidence that nurses can achieve the same effect without a geriatrician is low, resting on one small trial. That matches the broader Cochrane estimate of a 43% relative reduction across hospital patients outside intensive care, graded as moderate certainty (Burton et al., 2021), but it does not extend it to nurse-only delivery.

One study would overturn this conclusion for my question: a multicenter randomized trial of a nurse-delivered protocol in hip fracture patients, with blinded assessment, showing no difference in delirium incidence.

What the NURS 6341 Week 5 instructions ask for

The fifth NURS 6341 week has students appraise the strongest studies on their question. State the inclusion rule, appraise each study with a named tool, explain disagreements and state confidence in the evidence. Judgment supported by method is rewarded, so reporting results without weighing them loses points. Cite appraisal frameworks in APA 7. GRADE and Cochrane tools are common choices. The appraisal weighs evidence, not clinical decisions. If evidence in your specialty is thin, say so and appraise what exists. Explain why studies disagree before judging the body of evidence. A table with each study's design, sample, intervention, outcome measure, result and risk of bias helps readers compare quickly. The sections on disagreement and confidence then follow in prose.

How the NURS 6341 Week 5 example is put together

A handful of studies, not a shelf, and each one is worked rather than mentioned. The appraisal opens with the question and the inclusion rule that produced this set, so a reader knows what was left out and on what basis. Each study then takes a paragraph carrying its design, its sample, the effect it reported and the threats to its validity, in that order and in plain language. A comparison section follows, and it is where the document earns its name: studies that disagree are set against one another and the disagreement is explained through design, population or measurement rather than waved off. A synthesis paragraph states what the set supports, at what strength, for whom. The last line says what would change the verdict.

Reading the NURS 6341 Week 5 rubric

Appraisal rubrics look for judgment supported by method, and they are unforgiving about the gap between reporting a study and weighing one. The example earns the analysis row by ending every paragraph on what the design permits rather than on what the authors concluded. A second row covers synthesis, which is why the comparison exists as a section rather than as a closing sentence. Losses follow a pattern. An appraisal that walks through studies and stops has described a set. One that reports only agreeing studies has selected instead of appraised. Confidence stated more strongly than the designs allow costs the analysis row outright, and a missing inclusion rule leaves the whole set unexaminable.

NURS 6341 Week 5 help from the desk

Appraisals score poorly when they summarize each study's findings. Weigh design and bias instead. A second weakness is ignoring disagreement. Explain why one trial found nothing. Writers also skip a confidence statement. State it with reasons. Avoid rating all studies the same. Show differences. Name the tool. A sentence explaining that a null trial used a different control group shows careful reasoning. Close with the confidence level and what would raise it. Make sure the confidence statement follows from the appraisal above it. Name the appraisal tool in the opening paragraph.

NURS 6341 Week 5 questions, answered

Which appraisal framework does the example use?

It works through design, sample, measurement and threats to validity, which is the reasoning most published tools formalize. Where a section names a particular instrument, the same appraisal is arranged into that form. Naming a tool and then not applying its criteria is a familiar way to lose the analysis row.

Does the appraisal cover clinical decisions?

It appraises what the studies can support and stops at that boundary. No treatment is recommended for anyone, no medication is named, and nothing in it functions as advice for practice. What the writing establishes is the strength of an evidence base, which is what this assignment is asking to see.

What if the evidence in my specialty is thin?

Then the appraisal says so, and that is a defensible finding rather than a failure. Thin bases are common in narrower fields. The example is written so a small set with acknowledged weaknesses reads as honest appraisal, and rubrics here reward that honesty more than a manufactured claim of strength.
