Hospital-acquired Pneumonia Prevention: Intervention, Evaluation & Research

The purpose of this study is to determine the effectiveness of a universal, standardized oral care protocol on prevention of non-ventilated hospital-acquired pneumonia (NV-HAP) in the acute care setting. In the course of the year-long study, the research team will provide educational and materials support for oral hygiene on two interventional units (one medical; one surgical) and two control units (one matched medical; one surgical). At the end of the study, the research team will evaluate existing hospital data to determine the number of NV-HAPs in the interventional and control groups.

Prior to the study, the research team will have a lead-in period where education will be provided to the interventional groups and demonstration of desired oral care practices for patients (September 1-30, 2018) Design Previous research on the effectiveness of oral care for NV-HAP prevention has primarily relied on pre/post intervention study designs. In order to enhance compliance and avoid contamination of both the treatment and intervention groups, the research proposed the use of cluster randomization.

ICD-10 codes and a standardized CDC definition of non-ventilator hospital-acquired pneumonia will be used to determine the baseline incidence on NV-HAP for the 12 months prior to study implementation. The incidence will be expressed as both an overall incidence based on total patient days, as well as a rate per 1000 patient days.

The research team will follow the consolidated standards of reporting trials (CONSORT) research methods and reporting for pragmatic trials (2010). The research team will implement the HAPPI protocol using Stetler's model of implementation science. Overall the implementation process will be guided by Influencer Model ™ .

Methods There are no experimental procedures or medications use proposed in this study. The study consists of implementing a standardized oral care protocol (Attachment A) which are components of basic nursing care. Previous research has found that opportunities for oral care were often missed as part of daily care. The research team proposed to set specific standards and protocols for delivery of oral care on the intervention unit and to monitor the amount of oral care provided on both the control and intervention units.

The evidence-based oral care protocol consists of:

* oral care assessment by a RN to determine type and frequency oral care
* brushing the teeth with a soft-bristled toothbrush and plaque removing toothpaste
* rinsing with a non-alcohol based mouth wash
* application of lip and mouth moisturizer
* use of 24-hour suction toothbrush kits for high aspiration-risk patients who meet criteria, per oral care protocol

The study coordinator will provide educational information and support on the study units for use of the oral care kit and implementation of oral care after meals and before bedtime on the interventional units. As part of validation of oral care, the coordinator will make rounds on patients on the study units and validate and audit oral care activities with the patient/family and encourage their participation in oral care and with documentation checks. On the control units, the coordinator will also make rounds and evaluate oral care frequency in a non-conspicuous manner and through documentation.

Eligibility Criteria:
