When I was a resident, one attending asserted he’d rather have a resident at bedside making the evaluation than Harvey Cushing (the father of neurosurgery) at home.

Technology has improved and, today, diagnoses can often be made remotely.

Still, when a nurse beckons, and says she’s worried, you should listen. A recent paper supports that assertion.

The title is self-explanatory: The fifth vital sign? Nurse worry predicts inpatient deterioration within 24 hours.

The article concluded that nurses’ pattern recognition and sense of worry provides important information for detecting acute physiologic deterioration.

The study focused on a single tertiary care academic hospital that had high standards for hiring registered nurses. The researchers recorded nurses’ perception of patient potential for deterioration on two medical and two surgical hospital units. The scoring was simple. A score of zero was no worry at all. A score of four was “five alarm” worry. [Five alarm on 0-4 scale should remind readers of an analogous scale in the movie Spinal Tap.] More broadly, a score of 2-4 suggested the nurse believed the patient may be deteriorating.

 

Nurses filled out a form for their sense of worry at the beginning of each shift for each of their patients. They updated their number if their perception changed.

Nurses collected whether they notified the provider to come to the bedside, and whether the provider showed up to evaluate the patient.

Highly experienced charge nurses were also asked to independently record their predictions for a subset of patients.

The collected data was evaluated by three reviewers. A physician of the same specialty to which the patient was hospitalized – but otherwise had no contact with the patient. An experienced nurse who had no contact with the patient. And a physician, nurse, or NP who had no contact with the patient.

How did our Nostradamuses do for 3,000+ patients?

Pretty good.

Nurses recorded calling the provider (usually a physician assistant, nurse practitioner, or resident)—either to inform them of the patient’s status or to request them to come assess the patient—a total of 1314 times, and recorded the provider coming to the patient’s bedside due to patient deterioration 686 times. The number of potential deterioration events identified by nurses was 492. Additionally, there were 169 outcome events in total (86 RRT (Rapid Response Team) calls, 76 transfers to the ICU, and 7 codes).

Of the 492 potential deterioration events identified by nurses, 380 (77%) were confirmed by reviewers. Reviewer confirmation rates by nurses’ years of experience varied. Nurses with less than 1 year of experience had a significantly lower accuracy rate compared to nurses with more than 1 year of experience (68% vs 79%, P = 0.04).

Physicians came to bedside in proportion to the nurses’ worry.

When the WF was 2, nurses called the provider in 93% of cases, and providers assessed the patient at the bedside in 29% of cases;

These proportions increased to 97% and 38%, respectively, for a WF of 3; and to 98% and 43%, respectively, for a WF of 4.

The probability of an RRT call taking place in the following 24 hours was 16% after a WF of 2 or above, 37% following a WF of 3 or above, and 63% following a WF of 4.

The authors concluded that nurses’ judgement captured through this simple score is predictive of inpatient deterioration: 77% of the potential deterioration events identified by nurses were confirmed by an independent set of reviewers, and a patient with a WF of 3 or more is 40 times more likely to require ICU transfer in the next 24 hours (likelihood ratio = 40.4). This suggests that the nursing staff’s sense of worry, whether through analytical skills or through pattern recognition, is very accurate in identifying deteriorating patients and should be more consistently valued and utilized, considering incorporation into the medical record.

Is the study applicable to all hospitals? Maybe. Maybe not.

Data collection was conducted in a single tertiary referral center that hires carefully selected and highly trained registered nurses. The accuracy of these WF scores could change if conducted in a different center, where nurses might have different skillsets.

In other words, not all nurses in all settings are equal. And even in this study, more experienced nurses were more accurate in predicting patient deterioration.

If the worry factor is included in the electronic medical records, physicians would be well advised to be aware of that score. A WF score of 4 with no physician response -after being notified- will not help the patient or the potential legal defense.

And even with lower scores that still are associated with “worry”, some type of physician response – even if only a written analysis as to why the patient is likely stable and does not need hands-on evaluation – would be better than staying isolated in your medical record lane.

The moral of the story: Listen to nurses. They are at bedside more than you are.  What they see over time may be the most significant findings. But unless you ask/listen to the nurses these observations risk going ignored. There are analogs in the medico-legal space as well. A knowledgeable advisor is invaluable.

So, my former attending in neurosurgery might now add:

He’d rather have a resident or worried nurse at bedside making an evaluation than Harvey Cushing (the father of neurosurgery) at home.
