Evaluation of Physical and Mental Workload and Transfusion Time in Trauma Resuscitation.

BACKGROUND: Trauma resuscitation is time sensitive and complex. Whole blood (WB) and blood components are standard treatments for trauma related hemorrhage, yet their nursing workload and transfusion time have not been well evaluated. PURPOSE: To assess feasibility of a simulation-based crossover trial and obtain preliminary estimates comparing nursing workload and transfusion completion time between WB and blood component administration. METHODS: A randomized crossover pilot study using in situ simulation was conducted with experienced trauma nurses. Time-motion analysis measured transfusion completion time, and the National Aeronautical and Space Administration Task Load Index assessed workload domains. RESULTS: Strong feasibility was demonstrated across recruitment, retention, adherence, and completion. WB was associated with significantly shorter transfusion time, lower overall workload and mental demand, less effort, and better perceived performance. CONCLUSIONS: These findings support the feasibility and justify a fully powered trial. WB may improve resuscitation efficiency and reduce cognitive burden, with potential implications for patient outcomes and nursing workflow.

Military nursing at the forefront: the Army Forward Surgical Team.

From World War II to current conflicts, history has validated the need for early surgical intervention to save lives and established the need for FSTs. Historically 10% to 15% of soldiers wounded in action require surgery to control hemorrhage and to provide stabilization sufficient for evacuation to a medical treatment facility where definitive care can be provided. Undoubtedly, many lives were saved in past conflicts because resuscitative surgery and care were available a short time after being wounded. The need for surgical stabilization for patients to survive a long evacuation was well-established during military operations such as Operation Desert Storm. Resuscitative surgery capability must be present on the battlefield, and this capability must be able to move with the units the FST is supporting. These two imperatives were the driving force of the creation of the US Army's FSTs: they are light, easily transportable, and able to keep pace with the supported units. FSTs are an integral and essential element in providing surgical care to save soldiers' lives on the modem battlefield. The US military has been involved in more operations and deployments since the end of the Cold War than in the preceding years. FSTs participated in many of these operations and have performed superbly. FSTs will continue to have a critical role in providing combat health service support to soldiers on the battlefield of the twenty-first century, and FST nurses will continue to be an indispensable asset.

Multiple imputation for missing data.

Missing data occur frequently in survey and longitudinal research. Incomplete data are problematic, particularly in the presence of substantial absent information or systematic nonresponse patterns. Listwise deletion and mean imputation are the most common techniques to reconcile missing data. However, more recent techniques may improve parameter estimates, standard errors, and test statistics. The purpose of this article is to review the problems associated with missing data, options for handling missing data, and recent multiple imputation methods. It informs researchers' decisions about whether to delete or impute missing responses and the method best suited to doing so. An empirical investigation of AIDS care data outcomes illustrates the process of multiple imputation.

Single-item graphic representational scales.

BACKGROUND: Single-item measures of constructs are parsimonious alternatives to multiple-item measures in many types of research. Before selecting a particular instrument, researchers must first determine whether to use a multi-item or single-item instrument to measure the concept to be evaluated. Currently, single-item measures are widely used for both pain and job satisfaction research. OBJECTIVE: To review theoretical and empirical studies of single-item measures, with an emphasis on graphic representational (faces) scales. METHODS: In this review, theoretical considerations, reliability, validity issues, and comparisons between single- and multiple-item measures are discussed. Faces scales are emphasized as an economical method for assessing such affective responses as pain and job satisfaction. RESULTS: Single-item measures in general, and faces scales in particular, can be valid and reliable measures for global concepts. CONCLUSIONS: Because of their ease of administration, lessened respondent burden, and global concept representation, single-item measures have great potential for various types of research. Nurse researchers should seriously consider single-item measures as part of their methodological research "toolkit."
