Variables included in PIM-3 score (5)
| PIM-3 Data collection form | ||
|---|---|---|
| Pediatric intensive care unit | ||
| Hospital Universitario San Ignacio | ||
| Name: | HC: | Age: |
| Systolic pressure (mmHg) | Unknown = 120 | |
| Write 0 if the patient is in cardiac arrest, and 30 if he/she is in shock or his/her blood pressure is so low that it cannot be measured. | ||
| Pupillary response to light | > 3 mm and fixed = 1; unknown/other = 0 | |
| It is used as a brain function index, do not register a finding as abnormal if it is due to drugs, toxins or local lesion | ||
| PaO2, mm Hg | Unknown = 0 | |
| Concomitant to FiO2 (not with mask) | ||
| FiO2 | Unknown = 0 | |
| At the same time as PaO2 if oxygen is with ETT or Hood chamber. Expressed from 0 to 1 (no percentage) e.g. 0.60 | ||
| Base excess in arterial or capillary blood | Unknown = 0 | |
| Mechanical respiratory assistance during the first hour of admission to the PICU | Yes = 1; No = 0. | |
| Includes nasal or mask CPAP and in BiPAP | ||
| Elective admission to the PICU for monitoring, procedure, revision of mechanical ventilation, postoperative elective surgery | Yes = 1; No = 0. | |
| It is considered elective when it can be postponed for more than 6 hours without causing adverse effects | ||
| Hospitalization for recovery from surgery or procedure as the main reason for admission to the PICU. | No = 0; Yes, recovery after cardiac bypass = 1; Yes, recovery after cardiac procedure other than bypass surgery = 2; Yes, recovery after noncardiac procedure = 3 | |
| Admission after cardiac bypass | Yes = 1; No = 0 | |
| Diagnosis of a known high risk | Spontaneous cerebral hemorrhage (1). Cardiomyopathy or myocarditis(2), Hypoplastic left heart syndrome (3), Neurovegetative disorder (4), Necrotizing enterocolitis as the main reason for admission to PICU (5) | |
| Diagnosis of a known very high risk | Cardiorespiratory arrest prior to admission to the ICU(1), Severe combined immunodeficiency(2), Leukemia or lymphoma after first induction (3), Bone marrow transplant recipient (4), Hepatic failure as the main reason for admission(5) | |
| Low-risk diagnosis as the main reason for admission. | Yes = 1 No = 0 In case of doubt = 0 | |
| 1. Asthma 2. Bronchiolitis 3. Croup 4 Obstructive sleep apnea 5 Diabetic ketoacidosis 6. Seizure syndrome | ||
The following equation was used to calculate the risk of mortality in the PIM-3 Score
PIM-3 = (3.8233 × pupillary reaction) + (−0.5378 × elective admission) + (0.9763 × mechanical ventilation) + {0.067 × [absolute (base excess)]} + (−0.0431 × TAS) + [0.1716 × (TAS2/1.000)] + {0.4214 × [(FiO2 × 100)/PaO2]} − (1.2246 × procedure with pump) − (0.8762 × cardiac procedure without pump) − (1.5164 × noncardiac procedure) + (1.6225 × very high-risk diagnosis) + (1.0725 × high-risk diagnosis) − (2.1766 × low-risk diagnosis) − 1.7928
Probability of death = eLogit/(1 + eLogit) (5)
