Week 4 Discussion: Initial Post
More Pressure Injuries on Our Unit: Worse Mattresses or Better Eyes?
On an illustrative 28-bed medical unit, hospital-acquired pressure injuries averaged four a quarter for two years. Then the count rose to nine, and the next quarter to ten. The rise began in the same month as two changes. Supply chain had moved the unit to a new mattress contract, and the unit had hired its first wound care nurse, who also redesigned the skin assessment field in the admission and shift documentation so that each bony prominence had its own entry. At the review meeting, one group blamed the mattresses and another credited the wound nurse with finding injuries that had always been there.
Each explanation deserves its strongest form. The support surface case is plausible: foam mattresses designed for pressure relief cut pressure ulcer incidence by more than half compared with standard hospital foam (McInnes et al., 2015), so a cheaper surface could reverse that benefit. The detection case is plausible too. Surveillance bias arises when the more carefully an outcome is looked for, the more often it is found, and a unit that examines more closely will report more events without any change in care (Haut & Pronovost, 2011). The problem is that both explanations predict the same thing: a higher count. The count alone cannot decide between them.
What separates them is the stage of the added injuries. In the revised national staging scheme, stage 1 is intact skin with non-blanchable redness and stage 2 is partial-thickness loss, while stages 3 and 4 and deep tissue injury involve deeper tissue damage (Edsberg et al., 2016). Better detection should add mostly early injuries, found at stage 1 or 2 that previously went unnoticed or were noticed only later. A weaker surface should add injuries across stages, including deeper ones, since sustained pressure on bone damages the tissue beneath the skin first. On our unit, the added injuries were almost all early. Stage 1 and 2 injuries rose from three a quarter to eight or nine, while stage 3, stage 4, unstageable and deep tissue injuries stayed at one a quarter. I conclude that better detection explains most of the rise. I would not say it explains all of it, because a small surface effect could be hidden in the early stages.
My recommendation is to change how the measure is reported. The unit should report injuries by stage every quarter, so that early and deep injuries are not merged into one number, and should add a field noting whether the patient was on the new mattress at the time. If the deep injury count begins to rise, the surface question should reopen at once.
Reply to Megan
Megan, you raise a point I had not weighed: the wound nurse may also be staging differently, not just finding more. If moisture-associated skin damage over the sacrum is now being called stage 2 when it used to be charted as incontinence dermatitis, the early count would rise from a change in labeling rather than in detection or care. That would still support the conclusion that the mattresses are not the cause, but it would mean some of the rise is not real injury. An audit of a sample of the stage 2 photographs by a second certified nurse would show how much of the increase is classification. I would add that audit to my recommendation, since it costs a few hours and would settle the question.
Reply to Jason
Jason, your question about timing is a fair challenge to my confidence. You point out that deep tissue injury can appear days after the pressure that caused it, starting as a purple or maroon area that later declares itself (Edsberg et al., 2016). If the new mattresses are weaker, their deep injuries might be arriving late, and two quarters may be too soon to see them. I agree that the stage-mix argument is strongest for the early injuries and weakest for the deep ones at this point. That is why I would keep the mattress field in place and look again after a third quarter. If the deep injury count stays flat, the case for detection becomes much stronger. If it climbs, the unit will have caught a surface problem early, which is the reason to track it separately.

Reading the NURS 6231 Week 4 instructions
The fourth NURS 6231 thread commonly asks you to explain a change in an outcome. You name competing explanations, state what each predicts, test them against available data and say which is better supported. Faculty reward testing, and posts that choose the explanation matching experience earn little on analysis. Cite measurement and clinical sources in APA 7. Two explanations can predict the same total but differ in detail, such as stage mix. Stage mix alone may not settle the question, so look for other evidence. Staging definitions come from the National Pressure Injury Advisory Panel. A strong post lists predictions before looking at data.
How this NURS 6231 Week 4 example is built
Four paragraphs in the post, two replies beneath. The first paragraph describes the measured change in words: more hospital-acquired injuries recorded per quarter, beginning in the month both changes took effect. Paragraph two states each attribution in its strongest form, the support surface explanation and the detection explanation, and notes that both predict a higher count. The third paragraph finds the evidence that separates them, the mix of stages: better detection should add mostly early-stage injuries found sooner, while weaker support surfaces should add deeper injuries. On the sample's unit the added injuries are almost all early stage, and the post concludes that detection explains most of the rise. It closes by recommending that the unit report injuries by stage and track surface-related events separately. The replies question how confident that conclusion can be.
Where the marks sit in the NURS 6231 Week 4 rubric
Attribution threads reward testing, and posts that pick the explanation matching the author's experience and then support it tend to earn little on analysis. The sample collects its main credit by asking what each explanation predicts that the other does not, the move this week is built to exercise. Measurement awareness is assessed: recognizing that a detection change inflates a count is exactly the insight the course wants applied. Evidence handling is read for proportion, and a conclusion claiming certainty from one quarter's stage mix would lose ground. Citing a published staging definition strengthens the separating argument. Both replies here either weaken or refine the conclusion, which is the test the reply criterion applies. A post recommending closer attention from the unit's nurses has missed the point of the thread entirely.
Common NURS 6231 Week 4 mistakes, and how to avoid them
Attribution posts lose credit when they pick a cause and support it. Test both. Another common gap is ignoring surveillance bias. Explain how better detection raises counts. Writers also skip predictions. State what each cause would show. Avoid concluding from totals alone. Look at stages and timing. In replies, test whether a classmate's evidence could fit both explanations. A small table of predicted versus observed stage counts shows the test clearly. Close with the data you would gather next.

NURS 6231 Week 4 questions, answered
How can two explanations predict the same outcome?
When they operate through different mechanisms that both raise the count. Weaker support surfaces cause more injuries; better detection records injuries that already existed. Either produces a higher number. The sample's approach is to find a second observation where the explanations diverge, here the stage mix, since one mechanism adds mostly early findings and the other adds deeper ones.
Is stage mix enough to settle the question?
Not with certainty, and the post says as much. One quarter of data, a new staff member who may stage differently and a possible lag before deep injuries appear all limit confidence. The sample concludes that detection explains most of the rise and recommends reporting by stage going forward, which lets the question be revisited with more evidence instead of closed prematurely.
Where do staging definitions come from?
Most organizations use the staging system published by the National Pressure Injury Advisory Panel, and nurse-sensitive indicator programs such as NDNQI collect data using standardized definitions. The sample cites the staging source for its separating argument, since the claim that detection adds early stages depends on consistent staging. Your readings may assign a specific source, and citing it by name beats any paraphrase.
