Nursing workload in intensive care units: a study using the Therapeutic Intervention Scoring System-28 (TISS-28).
The Therapeutic Intervention Scoring System-28 (TISS-28) is an instrument that has been used to measure severity of illness and nursing workload in intensive care units (ICUs). ⋯ Most of the patients were males (60.0%) and their mean age was 51(+20.6) years. Surgical treatment (66.8%) and admissions from the operating room were predominant. The mortality rate was 25.0% and the average length of stay was 7.7 (+10.4) days. The mean TISS-28 score was 23 (range: 14-32 points). The lowest mean score was observed for patients from the Burn ICU and the highest mean score was obtained for patients from the Liver Transplant ICU. A change in TISS-28 scores was observed in the same ICU over the 7-day study period. Units differed in terms of severity of illness and nursing workload. Patients who died received a higher TISS-28 score than patients who survived (p=0.00). As the nursing staff are the largest economic investment in an ICU, so measuring nursing workload in different ICUs from different centres can contribute to the estimation of nursing staff required according to the specific demands of the units.

The level of knowledge of respiratory physiology articulated by intensive care nurses to provide rationale for their clinical decision-making.
The combination of intensive care knowledge, and the ability to articulate analytical decision-making processes to the interdisciplinary team, enhances the clinical credibility of the intensive care unit (ICU) nurse. The objective of this paper is to outline a study firstly, assessing ICU nurses' ability in articulating respiratory physiology to provide rationale for their clinical decision-making and secondly, the barriers that limit the articulation of this knowledge. ⋯ Thematic analysis identified the barriers limiting this use of respiratory physiology as being inadequate coverage of concepts in some ICU programmes; limited discussion of concepts in clinical practice; lack of clinical support; lack of individual professional responsibility; nurses' high reliance on intuitive knowledge; lack of collaborative practice; availability of medical expertise; and the limitations of clinical guidelines and protocols. These issues need to be addressed if nurses' articulation of respiratory physiology to provide rationale for their clinical decision-making is to be improved.

The implementation of tight glycaemic control (TGC) is becoming accepted best practice within intensive care units throughout the world. It is recommended by the Surviving Sepsis Campaign and is included in the sepsis care bundle. The major impact of TGC is currently thought to be associated with reduced morbidity and mortality. ⋯ The transfer of patients from the intensive care unit to the operating theatre or for computerised tomography during intensive insulin therapy is also hazardous. The purpose of this paper is to describe a series of nurse led pilot studies which aimed to introduce the process of TGC whilst maintaining patient safety. The results demonstrate the effectiveness of a staged approach and the achievement of TGC.

The impact of an evidence-based practice education program on the role of oral care in the prevention of ventilator-associated pneumonia.
Despite strong evidence in the literature on the role of oral care in the prevention of ventilator-associated pneumonia (VAP), nurses continue to view oral care as a comfort measure with low priority and utilise foam swabs rather than toothbrushes. Although an evidence-based oral care protocol existed and best-practice oral care tools were available, the VAP rates had not significantly decreased even though nurses reported providing oral care. ⋯ The implementation of an EBP educational programme focused on patient outcome rather than a task to be performed improved the quality of oral care delivered by the nursing staff.
