Shin, Kim, Yoo, Kim, Kim, Kim, Chae, Lee, An, and Kim: Development and Evaluation of an Evidence-Based Nursing Protocol for Fever Management in Adult Patients

Abstract

Purpose

This study was designed to develop, to implement and evaluate a fever management nursing protocol for adult patients.

Methods

This study was conducted through seven steps following both the guideline development procedures of the Scottish Intercollegiate Guidelines Network and the Model of the Asan Medical Center Evidence-Based Practice, as follows: 1) identifying the clinical needs and composition of the protocol development group; 2) identifying and evaluating the evidence; 3) assessing the level of evidence and grading recommendations; 4) forming a protocol; 5) evaluating the protocol using an expert group validity test and identifying barriers to its implementation; 6) protocol development; and 7) evaluation of practical improvement measures following implementation of the protocol.

Results

The evidence-based protocol for fever management in adult patients was completed and includes five domains and 15 items. The protocol had good content validity (CVI=.90) and nursing practice could be improved after implementation of the protocol.

Conclusion

This nursing protocol can be used as a guide for nursing in febrile adult patients. We recommend that further guidelines be updated in an interdisciplinary manner in order to foster local adaptation of the best clinical practices.

Definition of fever 1. A new onset of temperature of≥38.3℃ is considered as a fever in critically ill adult patients. 2++ C .44  
2. Fever is defined as: (1) A single oral temperature>37.8℃; or 2) repeated oral temperatures>37.2℃ or rectal temperatures>37.5℃; or 3) an increase in temperature of>1.1℃ over the baseline temperature. 1+ B .55  
<Revised Statement for 2nd CVI>   1.00
A new onset of temperature of>37.7℃ is considered as a fever in adult patients.  
Temperature measurement 3. Fever is defined as the temperature of the tympanic membrane (although the body temperature can be measured at the axilla if tympanic membrane temperature measurement is not possible). 1+ B .66  
<Revised Statement for 2nd CVI>   .88
Fever is defined as the temperature of the tympanic membrane, but measurement of the temperature of axilla do not recommend in febrile patients

<Revised Statement for 2nd CVI>   1.00
Body temperature should be rechecked after the new onset of fever.
5. An ear tug should be used during measurement of the tympanic temperature in order to straighten the external auditory canal. The tug technique pulls the auricle of the ear in an upward and backward direction. 2++ B 1.00
6. An ear nearest examiner should be used for stability of measurement of the tympanic temperature. 1+ B 1.00
7. If a patient has been using a pillow, the tympanic temperature should be measured in the opposite ear so as to avoid a falsely elevated temperature. 1+ B 1.00
8. The lens filter should be clear and dry before using an infrared ear thermometer. 1+ B 1.00
9. The lens filter should be exchanged for a new one before every temperature measurement. 4 D .88

External cooling 11. External cooling can be used as a fever management intervention 1+ A .88
12. Side effects such as shivering, hunting phenomenon, tingling sense or discomfort about cold, should all be assessed following the application of external cooling. 2+ C 1.00
