ISOLATION PRECAUTIONS 3
The safety of patients and healthcare workers is the focus for maintaining compliance with
isolation precautions. To ensure compliance with the proper use of personal protective
equipment (PPE), staff members and visitors must be properly educated. Audits and surveys
were conducted on the use of PPE, using the correct isolation signs to identify patients with
multi-drug resistant organisms (MDROs), and whether patients were receiving education about
the MDROs. The audits were used to determine what areas needed education to increase the
safety of patients and staff members. Standards set by the Centers for Disease Control (CDC)
and the Joint Commission were used to develop the education. The stage theory and the concept
of transformational leadership were used to implement the change in practice. The results
showed that by increasing awareness of the isolation reports and providing education to staff
nurses, the documentation of patient education improved. Providing easy access to patient
education materials was planned for the project but the new materials were not yet available by
the completion of the project. With proper identification of patients requiring isolation, the
safety of patients and staff will be increased.

ISOLATION PRECAUTIONS 4
Transmission of multi-drug resistant organisms (MDROs) is an important issue identified
by the Joint Commission. Preventing the transmission of MDROs and healthcare acquired
infections is a challenge for all health care organizations. Staff members need to be
knowledgeable when asked questions during a survey by accreditation agencies, such as the
Centers for Medicare and Medicaid Services (CMS) and the Joint Commission. The surveyors
expect staff to know information about the organization’s quality and safety programs. Staff
members are often asked about infection control issues and what the organization does to resolve
or prevent problems to improve patient outcomes (Patrick & Hicks, 2013). It is due to these
expectations that an education project was implemented to increase the ability of staff to
demonstrate the proper use of isolation precautions, handwashing and wearing personal
protective equipment. Communication between staff members, patients, and visitors about
isolation precautions improves patient safety, increases the patient’s trust in their care, and also
has been shown to increase patient satisfaction (Levers & Farshait, 2014).
Background
The Centers for Disease Control and Prevention recommends a multidisciplinary method
to monitor and improve adherence to recommended isolation precautions (CDC, 2009).
Education needs to include all direct patient care staff members in order to promote a change in
behavior and a culture that supports and encourages adherence to the prevention practices (CDC,
2009). The Joint Commission requires organizations to provide education about MDROs during
staff orientation and on a regular basis, to include processes for isolation precautions and how to
report any issues or suggest improvements (Joint Commission, 2010a). A prospective audit by
Russell, Young, Leung, and Morris (2015) demonstrated that educating staff and providing them
with a reference card had a positive effect on compliance with transmission based precautions.

ISOLATION PRECAUTIONS 5
Other studies have shown the influence of staff members perceptions and attitudes on the use of
PPE and compliance with infection control guidelines (Gralton, Rawlinson, & McLaws, 2013;
Stein, Manarawo, & Ahmad, 2003). According to the literature, increasing staff knowledge and
awareness about MDROs will improve compliance and patient safety. Patients and their families
should also be educated about the need for isolation precautions. Visitors compliance with hand
hygiene and use of PPE helps decrease the incidence of exposing other individuals to MDROs.
The Joint Commission requires nurses to educate patients and their families about infection
prevention and control (Joint Commission, 2010b). This study will provide strategies to help
organizations comply with the requirements of the regulatory agencies.
Objective
The overall goal for this project was to decrease the incidence of healthcare associated
infections. The Agency for Healthcare Research and Quality (AHRQ) encourages patients,
families, and healthcare professionals to work together to improve the safety and quality of care
(AHRQ, 2013). The AHRQ has developed a guide for hospitals to engage patients and family
members in the plan of care. This guide is based on research that indicates if patients and
families are engaged in health care it can lead to improvements in safety and quality (AHRQ,
2013). Teaching patients, visitors, and healthcare workers the reasons for isolation precautions
can help to decrease the occurrence of healthcare associated infections.
To properly plan for this project, staff member compliance with the use of PPE was
audited. A root cause analysis (RCA) was completed to examine potential barriers interfering
with the proper use of PPE and identification of patients that require isolation. The purpose of
this project was to analyze the process of identifying a patient with a MDRO, measure and find a

way to improve staff knowledge and compliance with the use of personal protective equipment
(PPE), and improve the patient education process related to MDROs.
Methods
Project Site
This project was conducted at a 475-bed urban hospital. Auditing and interactions with
the staff were focused on the medical-surgical units of the hospital. The staff on the medical-
surgical units care for complex patients with wide ranging diagnoses. These diagnoses include,
cancer, stroke, renal disease, neurological problems, urological problems, post orthopedic
surgeries and various other post-surgical patients.
Root Cause Analysis
A RCA is the identification of possible actions or situations that lead to a particular
outcome (Johnson, 2012). The focus is on processes and system design and how to implement
improvements to prevent patient harm. A RCA was conducted with a staff nurse, the clinical
unit leader, staff responsible for patient bed placement, and the infection preventionist. The RCA
was conducted to identify barriers in wearing PPE and providing patient education.
During the RCA, the group addressed the following questions: 1) Are there current
policies and procedures that address the process for identification of patients with MDROs and if
so, are they available to staff? 2) Are the staff involved, qualified, and trained to perform the
necessary tasks? 3) Are the necessary tools and equipment easily accessible to the staff? 4) Do
automatic alerts or flags function correctly? 5) Does the patient’s record give clear information
about past MDRO isolation and is this information available upon admission to hospital? A
RCA diagram was used to depict the questions asked and possible causes that may lead to errors
in missing the MDRO identification. A category labeled People represents the questions about
![Page 7: cooneydmsn.weebly.com · Web viewThe surveyors expect staff to know information about the organization’s quality and safety programs. Staff members are often asked about infection](https://reader036.vdocuments.net/reader036/viewer/2022090613/609e5ef8260c6964de34a714/html5/thumbnails/7.jpg)
ISOLATION PRECAUTIONS 7
proper staff training, staff compliance with PPE use, and communication through the use of
alerts in the computer system. The Process category looks into the different types of reports that
are used to identify patients with MDROs. Equipment tries to identify if signage and PPE are
available for use. The Materials category asks questions about education materials, prior audits
for proper signage and PPE use, and identifying if policies and procedures are in place to
recognize patients needing isolation. The final category is Environment. This portion of the
diagram looks for possible barriers to implementing precautions and using the PPE.
Data Collection
A patient needing isolation precautions has a sign placed on the door alerting staff to
wear proper PPE. Auditing of the isolation signs on the medical-surgical units was performed
three to four days per week over the span of four weeks. A list prepared by the infection
preventionists is sent daily to the inpatient units identifying those diagnosed with MDROs who
need to be in isolation precautions. With the use of the MDRO list, each patient room was
observed to determine if the correct isolation sign was in place. Another indication that a patient
needs to be in isolation is a color-coded border around the room on the electronic bed board.
The bed board information was compared to the MDRO list and the signs on the patient doors.
The presence or absence of the correct isolation sign was recorded.
Data from two other audits completed by the infection preventionists was examined to
develop a baseline for what areas needed interventions to improve compliance. One audit
focused on whether staff members wear the proper PPE when entering an isolation room. A
random sampling of observations on the in-patient units was collected each month. The other
audit was completed by reviewing nurses’ documentation of isolation education in patient charts.

ISOLATION PRECAUTIONS 8
An informational survey was distributed to the nursing staff. Questions on the survey
inquired about the use of personal protective equipment, educating patients and families about
isolation, documentation of isolation and education, and the availability of educational materials
to distribute to patients. The surveys were available for staff to complete in the unit break
rooms. To ensure participation, the clinical unit leaders were asked to mention the survey in the
huddles that take place at the beginning of each shift.
Theory
ANA Scope & Standards of Practice
Three Nursing Professional Development Standards of Practice were addressed during
the planning and implementation of this project. A standard which emphasizes identifying issues
and trends is utilized to improve processes for identifying patients with MRDOs. The standard
focuses on using data to identify needs and evidence of gaps in knowledge, skills, and practice
(ANA, 2010). Comparing data from various MDRO reports provides opportunities for
developing the most efficient and accurate report. This data helps to identify a necessary change
in practice, which can lead to improved quality reporting and safer patient care.
Another planning standard describes creating a proposal that will help to develop various
methods to reach the anticipated goals (ANA, 2010). Various activities were designed to help
meet the objectives set for each project goal. For example, chart audits were used to check for
compliance with documentation of isolation type and providing the patients with isolation
education. A survey of the staff helped to identify possible barriers in the use of PPE. A visual
check was completed to determine if the proper signage was in place outside of patients’ rooms
that were identified as having a MDRO. Planning also included collaborating with quality
specialists and the Infection Preventionists to develop a comprehensive project. Having staff

members that were directly affected by the project, as well as quality specialists, involved in the
planning process helped to keep communication open and helped to improve success in reaching
project goals.
The facilitation of a positive learning and practice environment meets another standard’s
goals (ANA, 2010). Part of providing quality patient care is ensuring that the patient is given
education about their disease process. Nurses should not have barriers in providing evidence-
based education to the patients. One activity during this project was to initiate a streamline
process for providing MDRO education for the patients. This involved creating information
cards with education about the precautions needed to prevent the spread of the different types of
MDROs to other patients, staff, or family members. Having this information readily available in
a card format, ensures nurses will not have to spend extra time retrieving the information and can
spend more time with the patients. This helps to create a more positive practice environment.
Leadership and Change Theory
The problem with proper and timely identification of patients with MDROs was
addressed with the Stage Theory. A four-stage model developed by Kaluzny and Hernandez
(1988), as cited in Butterfoss, Kegler, and Francisco, 2008, was adapted from the original stage
model by Kurt Lewin (1951). The Stage Theory focuses on change as a series of steps that must
each be achieved before proceeding to the next step (Butterfoss, Kegler, & Francisco, 2008). The
change is a gradual process. Step one is awareness or defining the problem. Information about
the MDROs needs to be provided to staff members. This information should include definitions
of the types of MDROs and how they are transmitted to other people. Step two is adoption or
initiating action. Actions include presenting ways in which the nursing staff can influence
prevention of transmission of the organisms. This includes proper signs on the door to patient
![Page 10: cooneydmsn.weebly.com · Web viewThe surveyors expect staff to know information about the organization’s quality and safety programs. Staff members are often asked about infection](https://reader036.vdocuments.net/reader036/viewer/2022090613/609e5ef8260c6964de34a714/html5/thumbnails/10.jpg)

rooms, wearing PPE, handwashing, and cleaning rooms and equipment after patient use. Step
three is to implement the change. Implementation involves educating all staff members on the
isolation precautions. Step four is institutional change. Leaders and Infection Preventionists
need to continue to monitor and encourage compliance with the process.
The concept of Transformational Leadership, proposed by MacGregor Burns (1978),
involves leaders demonstrating the need for change through vision and inspiration in order to
influence their followers (Marshall, 2011a). In order for this project to be successful, the staff
members need to be convinced that the process for identifying patients with MDROs and
wearing the appropriate PPE is important and effective. Leaders will play a large role in
showing staff the importance of the change in practice. A transformational leader explains why a
change is needed and what each staff member needs to do to help make the change possible
(Luzinski, 2011). Not only do leaders need to show support for the new or changing process of
controlling infections, leaders also need to follow up with staff members that are not compliant
with the process. Keeping an open dialogue between staff and the leader will keep the change
process evolving. Transformational leaders “strive for continuous quality improvement by using
and generating evidence to inform best practice and organizational policies” (Marshall, 2011b, p.
ix). Staff members who have a leader who treats them with respect, includes them in decision
making, and shows interest in the staff members’ suggestions, will be more open to a change
(Rolfe, 2011). If staff know that their suggestions are heard and considered, they will feel
supported and part of the team.
Results
Prior to initiating the quality project, project leaders conducted three audits to determine
areas for improvement. Three months of data pertaining to documenting patient MDRO
![Page 11: cooneydmsn.weebly.com · Web viewThe surveyors expect staff to know information about the organization’s quality and safety programs.

ISOLATION PRECAUTIONS 11
education in the patient chart was reviewed. The results showed a low percentage of proper
documentation was currently being completed (see Appendix A). The target goal is for the
documentation to be completed at least 95% of the time. The average over three months
exhibited that only 38% of the patients identified with an MDRO received the proper education.
A barrier identified in the survey distributed to the staff nurses showed that there was a need for
more patient educational materials (see Appendix B). An audit on the use of proper isolation
signs outside of the patients’ rooms indicated that there was a need for more education and
interventions for this process (see Appendix C). Correct signage was in place approximately
38% of the time.
Education was given in multiple small group sessions with the nurses on the medical-
surgical units of the hospital. Nurses were shown where to properly document patient education
in the electronic medical record as well as the new education materials that were created for the
patients. These educational sessions took place over several weeks and included teaching the
nursing staff on both day and night shifts. The clinical unit leaders on each unit were reminded
to review the MDRO report that is faxed to the unit each day to ensure that the proper isolation
signs are in place on the patient door frames.
Audits were conducted after the educational sessions. Creating awareness and new
information seemed to have a positive effect on the performance of the staff nurses. Compliance
with PPE use and hand hygiene was maintained between 95% and 97%. Documentation of
patient MDRO education averaged 38% before and after education for all the units combined.
There was significant improvement on some of the individual units (see Appendix D). For
example, 6SE increased from an average of 6% correct documentation through August 2016 to
50% in October 2016. Proper use of isolation signage improved from 38% to 67% (see

Appendix C). Continued education and reinforcement on all units should help the organization
reach the target goal of 95% for correct signage and documentation.
Discussion
Due to the short amount of time that passed between educating the staff and completing
the follow-up audits, the results may not show a true trend in improvement. To assess an
accurate improvement in behaviors, monthly audits should be completed for at least three months
beyond the completion of the instruction. A larger percentage of the staff nurses should also
receive the documentation education. The nurses who received the information were
appreciative of the new education materials for the patients. The actual cards for the patients
were not available for the project implementation. The cards were approved by the necessary
committees but had not passed through the marketing department or the print shop. Having the
education cards available on the units will keep the need for patient education apparent to the
nurses. The slight improvement in the audit data indicates an increase in safe care provided to
the patients by the staff. The behaviors emphasized in this project need to be continued in order
for positive trends to be sustained.
