title: "Realising the potential of critical care nurses": an exploratory study of the factors that affect and comprise the nursing contribution to the recovery of critically ill patients.
abstract: BACKGROUND
  This study seeks to make evident the complexity of issues associated with the delivery of care by nurses to the critically ill. Emphasis had been placed on the results and implications of these for nursing practice. For a more in-depth account, the full report can be accessed on www.lscn.co.uk.
  
  
  METHODS
  Following multi-centre research ethics committee approval, 10 critical care units participated in the 3-month study. Data collection comprised 231 nurse interviews and 51 relative interviews during 33 observation participation periods.
  
  
  RESULTS
  Analysis demonstrated that the context of the critical care unit, in terms of geographical layout, unit activity, case mix and skill mix of nurses, had a major effect on the ability of nurses to contribute to the recovery of the critically ill. The effectiveness of the nursing resource appeared to be a function of knowledge (theoretical and patient related), experience and exposure. Nurses who were unused to a particular environment were not seen to be as effective as those who were. A model was constructed that identified the central tenets upon which nursing care can be optimised or compromised. When nursing care was optimised the difference nurses made potentially decreased risk to patients, enabled timely patient progression and increased the potential for patient recovery.
  
  
  CONCLUSIONS
  The results confirm that nurses have a significant contribution to make in the recovery of patients who have experienced critical illness. Recommendations are far reaching and include the need to develop a valid and reliable tool which addresses patients' need for nursing in terms of nurses' knowledge and experience, patient dependency and decreasing clinical risk across the continuum of care. Current nursing workload tools and patient:nurse ratios were seen to lack validity because they do not appraise the context in which care is delivered, define all nurses as equal and concentrate on activity rather than the effect nurses can have on the outcome of the critically ill.
