    Journal: J Intensive Care Med; 2015 Sep; 30(6):344-50. PubMed ID: 24457146.
    Abstract:
    BACKGROUND: To introduce an updated version of the original Therapeutic Intervention Scoring System (TISS) applicable to critically ill children (TISS-C). This version was designed to assess patient acuity and nursing workload (NW) and to determine a relationship between such assessment and the incidence of adverse events. METHODS: Reviewing previous versions of TISS, an updated TISS-C was developed. Items inapplicable to pediatric critical care were eliminated; items current to critical care were added; and items still valid were edited. The point system accounts for the wide range of care provided. Random patients from a predetermined period had TISS-C scores calculated. The TISS-C scores were also calculated on patients with documented adverse events. Baseline scores were compared with scores of patients in whom adverse events had occurred. We determined the pediatric intensive care unit (PICU) NW to be the product of the TISS-C score and the patient-nurse ratio (PNR). RESULTS: One hundred twenty-five random patients had a mean TISS-C of 14.6 ± 11.8. Patients with any adverse event (98) had a TISS-C of 19.9 ± 11.6 (P < .05). Using our PICU mean PNR of 1.4 (20 patients/14 nurses), the NW for patients with more severe events was 33.6 ± 15.9. CONCLUSIONS: Critically ill pediatric patients are more vulnerable to experience adverse events when their derived NW values are high. It is postulated that a critical NW exists, where adverse events are more likely to occur.
