ABSTRACT The reported actual compliance for severe sepsis bundles was very low, suggesting the presence of barriers to their implementation. The purpose of this study was to assess the influence of full-time intensivist and nurse-to-patient ratio in Korean intensive care units (ICUs) on the implementation of the severe sepsis bundles and clinical outcome.
A total of 251 patients with severe sepsis were enrolled from 28 adult ICUs during the July, 2009. We recorded the organizational characteristics of ICUs, patients' characteristics and clinical outcomes, and the compliance for severe sepsis bundles.
Complete compliance with the resuscitation bundle and totally complete compliance with all element targets for resuscitation and management bundles were significantly higher in the ICU with full-time intensivist and a nurse-to-patient ratio of 1:2 (P < .05). The hazard ratio (HR) for hospital mortality was independently reduced by the presence of full-time intensivist (HR, 0.456; 95% confidence interval, 0.223-0.932), and a nurse-to-patient ratio of 1:2 was independently associated with a lower 28-day mortality (HR, 0.459; 95% confidence interval, 0.211-0.998).
The full-time intensivist and the nurse-to-patient ratio had a substantial influence on the implementation of severe sepsis bundles and the mortalities of patients with severe sepsis.

    ABSTRACT: There is a lack of information on critical care in Korea. The aim of this study was to determine the current status of Korean intensive care units (ICUs), focusing on the organization, characteristics of admitted patients, and nurse and physician staffing. Critical care specialists in charge of all 105 critical care specialty training hospitals nationwide completed a questionnaire survey. Among the ICUs, 56.4% were located in or near the capital city. Only 38 ICUs (17.3%) had intensive care specialists with a 5-day work week. The average daytime nurse-to-patient ratio was 1:2.7. Elderly people ≥ 65 yr of age comprised 53% of the adult patients. The most common reasons for admission to adult ICUs were respiratory insufficiency and postoperative management. Nurse and physician staffing was insufficient for the appropriate critical care in many ICUs. Staffing was worse in areas outside the capital city. Much effort, including enhanced reimbursement of critical care costs, must be made to improve the quality of critical care at the national level. Graphical Abstract
