Hand Hygiene Practices and Microbial Contamination on Feeding Tubes and Other Components of Feeding Systems

Not Applicable

Completed

• Conditions: Microbial Colonization; Adherence; Enteral Nutrition
• Interventions: Other: Adherence to Hand Hygiene

• Registration Number: NCT04240132
• Lead Sponsor: Istanbul Demiroglu Bilim University

Brief Summary

Enteral feeding tube (EFT) and component of feeding systems can serve as a reservoir of microorganisms, and the main reason is inappropriate hand hygiene practices. The aim of the project is to determine colonization of microorganisms on the EFT and other components and assess the relation between colonization and adherence to hand hygiene practices by healthcare workers in the intensive care unit.

This prospective, observational and semi-experimental study will be conducted in one year. The project will be completed with healthcare workers and 51 patients who are feeding enteral route via nasogastric tube at least for three days. The researchers will provide training to healthcare workers in accordance with the World Health Organization (WHO) Hand Hygiene Guidelines. Hand hygiene behaviors of the participants will be observed and the question forms will be filled before and after training by researchers. The samples for microbial analysis will be collected from the EFT by sterile swaps.

Detailed Description

Enteral Feeding Tube (EFT) such as Nasogastric Tube (NGT), Duodenal/Jejunal Tube and Gastrostomy Tube are frequently used in Intensive Care Unit (ICU). However, EFT is generally an omitted/neglected source of contamination. EFT can serve as a reservoir of Methicillin Resistant Staphylococcus Aureus (MRSA), which multiplies the risk of mortality by 2-2.5 times, for microorganism transmission. As a consequence of contamination of EFT, microorganisms, that may be manifest with the symptoms such as abdominal pain, distention, nausea, vomiting, diarrhea, may reproduce and progress to bacteremia, septicemia and even to death. In some studies, it is observed that there is a relation between the contamination on the external surface of EFT and contamination on the entry of EFT (hub), and it is also reported that the rate of contamination on the hub of the EFT and the environment of the patient is quite high. ICU nurses are responsible for sustaining safe and secure feeding, medication and fluid replacement of patients. Also, they provide enteral feeding products to patients as they are prescribed. Personnel training, proper processing procedures and developed enteral feeding protocols are shown to decrease the incidence of bacterial contamination on the enteral feeding tube

Arm && Interventions

Group	Intervention	Description
Adherence to hand hygene	Adherence to Hand Hygiene	The face-to-face interview will be held in an appropriate empty room in the intensive care unit (ICU) in a time schedule suitable for the healthcare workers. The researchers will provide training to healthcare workers working in the ICU in accordance with the World Helath Organization (WHO) Hand Hygiene Guidelines. One day training on nursing interventions related to enteral feeding treatment will be provided to nurses and their questions will be answered. At the end of the each training, trainees will be given a data collection form to assess the effectiveness of the training.

Primary Outcome Measures

Name	Time	Method
Adherence to hand hygiene at nurses	up to 12 weeks	Hand Hygiene Belief Scale will be used. The scale consists of 22 items on individual's beliefs on hand hygiene and perceptions on the importance of hand hygiene. The lowest total score is 22 and the highest total score is 110. Higher scores can be interpreted as having positive beliefs on hand hygiene.
Adherence to hand hygiene at auxillary service staff	up to 12 weeks	Scale for Hand Hygiene Compliance of Auxillary Service Staff will be used. It consist of 21 items and has 4 dimensions; "After contact with patient" (6 items), "Before contact with patient" (6 items), "risk of contact with blood and body fluids" (4 items), "after contact with patient environment" (5 items). The lowest total score is 0 and the highest total score is 84. Higher scores represent higher adherence to hand hygiene.
Microbial contamination rate	up to 12 weeks	The samples for microbial analysis will be collected from internal and external surface of the NGT and other components of the feeding system by sterile swaps from all of the participant patients.
