A pediatric early warning score (PEWS) predicts patient deterioration after transfer to a pediatric intensive care unit (PICU), according to a retrospective review of patients who were transferred to the PICU at a large children’s hospital during an 8-month period.
A pediatric early warning score (PEWS) predicts patient deterioration after transfer to a pediatric intensive care unit (PICU), according to a retrospective review of patients who were transferred to the PICU at a large children’s hospital during an 8-month period. Third-year pediatric resident opinion of patients’ risk for worsening does not have this strong association, however, the study showed. The PEWS tool used in the study is based on age-stratified respiratory rate, heart rate, and behavior ascertained at 4-hour intervals with scores ranging from 0 (all parameters normal) to 13 (all parameters abnormal). Physician opinion that the patient is at high risk of deterioration was defined as being placed by a senior resident on the senior sign-out (SSO) list, while deterioration was considered as the need for intubation, inotropes, high-flow nasal cannula, noninvasive mechanical ventilation, or aggressive fluid resuscitation within 12 hours of transfer to the PICU.
Of the 97 patients included in the study, 51 (53%) experienced a deterioration event in the 12 hours after PICU transfer. These patients had a maximum mean PEWS of 3.9 before transfer compared with a score of 2.9 in those patients who did not experience such an event. Further analysis showed that a PEWS ≥3 was significantly associated with risk of a later deterioration event, even after adjustment for age, gender, race/ethnicity, and whether the PICU transfer occurred within 24 hours of admission. On the other hand, the relationship between physician assignment to the SSO and a deterioration event was only marginal; physicians assigned patients who experienced a deterioration event within the 12-hour window to SSO 43% of the time and assigned patients who did not experience a deterioration event 30% of the time (Fenix JB, et al. Hosp Pediatr. 2015;5:474-479).
Commentary: Humbling but enlightening. Depending on intuition, a “blink response” or a gut reaction is essential in medicine. However, using evolving, evidence-based tools to enhance that approach may help us provide the best care to our patients, whether or not sick enough to be hospitalized.
