AIM: To determine the range of physical assessment skills practised by critical care nurses and their adoption factors.
STUDY DESIGN: This study uses a cross-sectional survey design. A self-administered questionnaire evaluating 40 physical assessment skills was conducted with 133 staff nurses (response rate: 96.4%) in three critical care units at a Malaysian government hospital between November 2019 and January 2020.
RESULTS: Most nurses applied 32 (80%) skills during every working shift, involving the vital signs and all body systems except the gastrointestinal system. Five skills (12.5%) were occasionally applied, while three skills (7.5%) were rarely applied or not part of most nurses' clinical practice. About 20% of the nurses did not routinely check the respiration rate. Medical and surgical intensive care unit nurses (U = 1129, p vital to critical care nursing roles. Concerns highlighted by the nurses should be addressed by nursing management so that the application of physical assessment skills can be enhanced, especially in critical care settings.
RELEVANCE TO CLINICAL PRACTICE: The findings indicated that physical assessment skills in critical care need to be improved. Education and training should emphasise these skills.
METHODS: Patients with an admission diagnosis of suspected or confirmed infection and fulfilling at least two criteria for severe inflammatory response syndrome were included in this study. Patients' characteristics, vital signs, and laboratory values were used to identify prognostic factors for mortality. A scoring system was derived and validated. The primary outcome was the 28-day mortality rate.
RESULTS: A total of 440 patients were included in the study. The 28-day hospital mortality rate was 32.4 and 25.2% for the derivation (293 patients) and validation (147 patients) sets, respectively. Factors associated with a higher mortality were immune-suppressed state (odds ratio 4.7; 95% confidence interval 2.0-11.4), systolic blood pressure on arrival less than 90 mmHg (3.8; 1.7-8.3), body temperature less than 36.0°C (4.1; 1.3-12.9), oxygen saturation less than 90% (2.3; 1.1-4.8), hematocrit less than 0.38 (3.1; 1.6-5.9), blood pH less than 7.35 (2.0; 1.04-3.9), lactate level more than 2.4 mmol/l (2.27; 1.2-4.2), and pneumonia as the source of infection (2.7; 1.5-5.0). The area under the receiver operating characteristic curve was 0.81 (0.75-0.86) in the derivation and 0.81 (0.73-0.90) in the validation set. The SPEED (sepsis patient evaluation in the emergency department) score performed better (P=0.02) than the Mortality in Emergency Department Sepsis score when applied to the complete study population with an area under the curve of 0.81 (0.76-0.85) as compared with 0.74 (0.70-0.79).
CONCLUSION: The SPEED score predicts 28-day mortality in septic patients. It is simple and its predictive value is comparable to that of other scoring systems.
