Background: Hospital-acquired pneumonia (HAP) and the need for positive-pressure ventilation (PPV) are significant postoperative pulmonary complications (PPCs) that increase patients' lengths of stay, mortality, and costs. Current tools used to predict PPCs use nonmodifiable preoperative factors; thus, they cannot assess provided respiratory therapy effectiveness. The Respiratory Assessment and Allocation of Therapy (RAAT) tool was created to identify HAP and the need for PPV and assist in assigning respiratory therapies. This study aimed to assess the RAAT tool's reliability and validity and determine if allocated respiratory procedures based on scores prevented HAP and the need for PPV., Methods: Electronic medical record data for nonintubated surgical ICU subjects scored with the RAAT tool were pulled from July 1, 2015-January 31, 2016, using a consecutive sampling technique. Sensitivity, specificity, and jackknife analysis were generated based on total RAAT scores. A unit-weighted analysis and mean differences of consecutive RAAT scores were analyzed with RAAT total scores ≥ 10 and the need for PPV., Results: The first or second RAAT score of ≤ 5 (unlikely to receive PPV) and ≥ 10 (likely to receive PPV) provided a sensitivity of 0.833 and 0.783 and specificity of 0.761 and 0.804, respectively. Jackknifed sensitivity and specificity for identified cutoffs above were 0.800-0.917 and 0.775-0.739 for the first RAAT score and 0.667-0.889 and 0.815-0.79 for the second RAAT score. The initial RAAT scores of ≥ 10 predicted the need for PPV ( P < .001) and was associated with higher in-hospital mortality ( P < .001). Mean differences between consecutive RAAT scores revealed decreasing scores did not need PPV., Conclusions: The RAAT scoring tool demonstrated an association with the need for PPV using modifiable factors and appears to provide a quantitative method of determining if allocated respiratory therapy is effective., Competing Interests: Dr Vines discloses relationships with Theravance Biopharma, Teleflex Medical, and the Rice Foundation.

Background: Clinicians need to deliver prognostic information to surrogates of nondecisional, critically ill patients so that surrogates can make informed medical decisions that reflect the patient's values. Our objective was to implement a new approach for communicating with surrogates of patients with chronic critical illness., Methods: Surrogate decision makers of patients who were difficult to liberate from mechanical ventilation were prospectively enrolled. Surrogates met with different members of the intensive care unit treatment team for sequential 15-minute appointments to receive patient-specific assessments and education on chronic critical illness. The feasibility and acceptability of this approach were determined. A 24-question comprehension instrument was developed to assess a participant's understanding that a family member was displaying features of chronic critical illness. Each question was scored from 1 to 5, with larger scores indicating greater comprehension., Results: Over a 15-week period, educational sessions for 9 mechanically ventilated patients were conducted. On average, 2 surrogates per patient (range: 1-4) and 6 members of the interdisciplinary team (range: 4-6) were at each meeting. Surrogates and clinicians had very positive impressions of the communication intervention. The average preintervention comprehension score was 85 of 120 (standard deviation [SD]: 8, range: 71-101). The postintervention comprehension score was greater by 5 points on average (SD: 9, range: -11 to +20 points, P = .04)., Conclusions: Surrogates of critically ill patients approved of this novel communication approach and had a greater understanding of the patient's medical condition after the intervention.
