Implementing a quick Sequential (Sepsis-Related) Organ Failure Assessment sepsis screening tool: an interrupted times series study

Objective The aim of this study was to evaluate the outcomes of implementing a sepsis screening (SS) tool based on the quick Sequential [Sepsis-Related] Organ Failure Assessment (qSOFA) and the presence of confirmed/suspected infection. The implementation of the 6-hour (6-h) bundle was also evaluated. Design Interrupted times series with prospective data collection. Setting Five hospital wards in a developing nation, Argentina. Participants 1151 patients (≥18 years) recruited within 24–48 hours of hospital admission. Intervention The qSOFA-based SS tool and the 6-h bundle. Main outcome measures The primary outcome was the timing of implementation of the first 6-h bundle element. Secondary outcomes were related to the adherence to the screening procedures. Results Of 1151 patients, 145 (12.6%) met the qSOFA-based SS tool criteria, among them intervention (39/64) patients received the first 6-h bundle element earlier (median 8 hours; 95% CI: 0.1–16) than baseline (48/81) patients (median 22 hours; 95% CI: 3–41); these times, however, did not differ significantly (p = 0.525). Overall, 47 (4.1%) patients had sepsis; intervention patients (18/25) received the first 6-h bundle element sooner (median 5 hours; 95% CI: 4–6) than baseline patients (15/22) did (median 12 hours; 95% CI: 0–33), however times were not significantly different (p = 0.470). While intervention patients were screened regularly, only one-third of patients that required sepsis alerts had them activated. Conclusion The implementation of the qSOFA-based SS tool resulted in early, but not significantly improved, provision of 6-h bundle care. Screening procedures were regularly conducted, but sepsis alerts rarely activated. Further research is needed to better understand implementation of sepsis care in developing settings

Prognosis factors and outcome of community-acquired pneumonia needing mechanical ventilation.

PURPOSE: To evaluate the variables associated with mortality of patients with community-acquired pneumonia who require mechanical ventilation and to determine the attributable morbidity and intensive care unit (ICU) mortality of community-acquired pneumonia. MATERIAL AND METHODS: Retrospective cohort study carried out in 361 ICUs from 20 countries including 124 patients who required mechanical ventilation on the first day of admission to the hospital due to acute respiratory failure secondary to severe community-acquired pneumonia. To assess the factors associated with outcome, a forward stepwise logistic regression analysis was performed, and to determine the attributable mortality of community-acquired pneumonia, a matched study design was used. RESULTS: We found 3 independent variables significantly associated with death in patients with community-acquired pneumonia requiring mechanical ventilation: simplified acute physiological score greater than 45 (odds ratio, 5.5 [95% confidence interval, 1.7-12.3]), shock (odds ratio, 5.7 [95% confidence interval, 1.7-10.1]), and acute renal failure (odds ratio, 3.0 [95% confidence interval, 1.1-4.0]). There was no statistically significant difference in ICU mortality among patients with or without community-acquired pneumonia (32% vs 35%; P=.59). CONCLUSIONS: Community-acquired pneumonia needing mechanical ventilation is not a disease associated with higher mortality. The main determinants of patient outcome were initial severity of illness and the development of shock and/or acute renal failure

Improving sepsis screening and care in a developing nation health setting: A description of implementation

Evidence on sepsis screening and care in developing nations is insufficient to inform implementation practices in hospital wards. The aim of this multi-method study was to describe and evaluate the implementation of a three-step intervention (sepsis screening, alert activation, care) in five wards in Argentina in 2017. The implementation involved three stages: (1) context assessment, (2) development/participation in implementation strategies, and (3) evaluation of intervention adherence. Results were variable. The context assessment (Stage 1) demonstrated the value of education, proactivity towards care and team structures. Strategies developed (Stage 2) included sepsis screening and response guide, education, team rounding, posters, champions, audit/feedback and knowledge brokering. In Stage 3, staff screened 92% patients (506/547) for sepsis at ≥60% of set times; only 33% (21/64) patients had a sepsis alert activated when needed. A similar proportion of patients who had alerts activated (n = 16, 76%) or not (n = 32, 74%) received at least one element of care. The use of implementation strategies resulted in adherence to some aspects of the intervention. Future research is needed to improve sepsis screening and alert activation and care in this setting

Comparison of 6% hydroxyethyl starch 130/0.4 and saline solution for resuscitation of the microcirculation during the early goal-directed therapy of septic patients

PURPOSE: The aim of this study was to show that 6% hydroxyethyl starch (HES) 130/0.4 achieves a better resuscitation of the microcirculation than normal saline solution (SS), during early goal-directed therapy (EGDT) in septic patients. MATERIALS AND METHODS: Patients with severe sepsis were randomized for EGDT with 6% HES 130/0.4 (n = 9) or SS (n = 11). Sublingual microcirculation was evaluated by sidestream dark field imaging 24 hours after the beginning of EGDT. RESULTS: On admission, there were no differences in Sequential Organ Failure Assessment score, mean arterial pressure, lactate, or central venous oxygen saturation. After 24 hours, no difference arose in those parameters. Sublingual capillary density was similar in both groups (21 ± 8 versus 20 ± 3 vessels/mm(2)); but capillary microvascular flow index, percent of perfused capillaries, and perfused capillary density were higher in 6% HES 130/0.4 (2.5 ± 0.5 versus 1.6 ± 0.7, 84 ± 15 versus 53 ± 26%, and 19 ± 6 versus 11 ± 5 vessels/mm(2), respectively, P < .005). CONCLUSIONS: Fluid resuscitation with 6% HES 130/0.4 may have advantages over SS to improve sublingual microcirculation. A greater number of patients would be necessary to confirm these finding

Incidence, risk factors and outcome of barotrauma in mechanically ventilated patients.

OBJECTIVE: To determine the incidence, risk factors, and outcome of barotrauma in a cohort of mechanically ventilated patients where limited tidal volumes and airway pressures were used. DESIGN AND SETTING: Prospective cohort of 361 intensive care units from 20 countries. PATIENTS AND PARTICIPANTS: A total of 5183 patients mechanically ventilated for more than 12 h. MEASUREMENTS AND RESULTS: Baseline demographic data, primary indication for mechanical ventilation, daily ventilator settings, multiple-organ failure over the course of mechanical ventilation and outcome were collected. Barotrauma was present in 154 patients (2.9%). The incidence varied according to the reason for mechanical ventilation: 2.9% of patients with chronic obstructive pulmonary disease; 6.3% of patients with asthma; 10.0% of patients with chronic interstitial lung disease (ILD); 6.5% of patients with acute respiratory distress syndrome (ARDS); and 4.2% of patients with pneumonia. Patients with and without barotrauma did not differ in any ventilator parameter. Logistic regression analysis identified as factors independently associated with barotrauma: asthma [RR 2.58 (1.05-6.50)], ILD [RR 4.23 (95%CI 1.78-10.03)]; ARDS as primary reason for mechanical ventilation [RR 2.70 (95%CI 1.55-4.70)]; and ARDS as a complication during the course of mechanical ventilation [RR 2.53 (95%CI 1.40-4.57)]. Case-control analysis showed increased mortality in patients with barotrauma (51.4 vs 39.2%; p=0.04) and prolonged ICU stay. CONCLUSIONS: In a cohort of patients in whom airway pressures and tidal volume are limited, barotrauma is more likely in patients ventilated due to underlying lung disease (acute or chronic). Barotrauma was also associated with a significant increase in the ICU length of stay and mortality
