Conditions: Surgical Wound Infection Preoperative Care Methicillin-Resistant Staphylococcus Aureus
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 192
Healthy volunteers: no

Brief summary:
To evaluate the efficacy and tolerability of 10% povidone-iodine in eliminating nasal carriage of Staphylococcus aureus and MRSA. To determine whether a more convenient, single-dose, pre-operative 10% povidone-iodine (PI) application is effective in reducing nasal carriage of S. aureus and MRSA. We expect a statistically significant decrease in S. aureus/MRSA colonization in nasal cultures taken perioperatively after intervention in patients who received pretreatment with PI as compared to patients who received normal saline (NS).

Detailed description:
This will be a prospective single-blinded randomized placebo-controlled trial of two applications of a nasal 10% Povidone Iodine (PI) solution used on the intranasal mucosal surfaces of each nostril in the preoperative holding area within 2 h prior to surgical incision compared with NS using the same technique. Both the PI and NS will be applied by rotating the swab over the intranasal mucosal surface for 15 seconds; this process will be performed twice for both nostrils, using a new swab for each application. Nasal cultures will be obtained prior to PI or NS application as well as intraoperatively 1 hour and 2 hours after first surgical incision. The primary study end point is the decrease in S. aureus/MRSA colony forming units (CFU) in nasal cultures taken within 2 hours after intervention in patients who presented with a positive preintervention nasal culture. A secondary endpoint is the presence or absence of surgical site infections within 30 days postoperatively

Arms:
arm 1: Application of Povidone-Iodine 10% prior to surgery to Nares arm 2: Application of 0.9% Sodium Chloride (NaCl) solution prior to surgery to Nares

Interventions: intervention 1: Povidone-Iodine 10% intervention 2: 0.9% NaCl Solution

STUDY SUMMARY: This consent form is part of an informed consent process for a research study, 
and it will provide information that will help you decide whether you want to take part in this study. It is 
your choice whether to take part or not.
The purpose of the research is: to determine if the use of preoperative (before surgery) Povidone- 
Iodine nasal swab can help decrease MRSA bacteria colonization in the nares (nostrils) and decrease 
the rate of surgical site infections. If you take part in the research, you will be asked to provide nasal 
cultures from both nares before, during, and after the surgery and to allow us to swab the nares with 
either saline solution (salt solution) or Povidone-Iodine (medication) solution before surgery. At the Pre- 
operating room and PACU, you will be asked a few questions about the tolerability of applied 
investigational drug. Your time in the study will take from when you arrive at the preoperative area until 
you are discharged after your surgery.
Possible harms or burdens of taking part in the study may be minor discomfort from the nasal swabs 
and possible benefits of taking part may be decreased rate of surgical site infections and contributing to 
medical knowledge.
Your alternative to taking part in the research study is not to take part in it.

Why is this study being done?
The purpose of this study is to determine if the use of Povidone-Iodine nasal swab before surgery can 
help decrease MRSA bacteria colonization in the nares and decrease the rate of surgical site infections.
Who may take part in this study and who may not?
Any patient presenting to University Hospital for a same day outpatient surgery may participate in this 
study as long as they meet the following inclusion criteria and do not meet the exclusion criteria.
Inclusion criteria include:

community-based English or Spanish speaking patients ages 18-80

willing and able to consent

American Society of Anesthesiology (ASA) rating of 1, 2, or 3 as determined by anesthesiologist

undergoing an outpatient surgery for at least 1 hour and up to 6 hours duration
Exclusion criteria include:

pregnancy

allergy to povidone-iodine

infectious indication for surgery or preexisting known infection/wound

immunocompromised state

use of chemotherapy or steroids within 30 days prior to surgery

use of antimicrobial therapy within 30 days prior to surgery

surgeries where field avoidance prevents intraoperative access to the nares
Why have I been asked to take part in this study?
Your participation in this study will help in progressing our understanding of surgical site infections and in 
assessing the efficacy of a novel method of preventing them.
How long will the study take and how many subjects will take part?
The study will last 2 years, but the patient’s participation in the study lasts only until discharge from 
University Hospital Same Day Surgery after their surgery. 200 subjects will take part in this study.
What will I be asked to do if I take part in this study?
If you decide to participate, a nasal culture will be obtained from both nares. You will then receive a nasal 
swab in both nares while in the preoperative holding area. This swab may contain either saline (placebo) 
or Povidone-Iodine solution (medication). Additional nasal cultures will be taken during the surgery as well 
as in the PACU recovery area. We expect those who receive the Povidone-Iodine swabs to have a 
decreased rate of surgical site infections. At the Pre-operating room and PACU, you will be asked a few 
questions about the tolerability of applied drugs as burning/itching, pain, irritation, epistaxis, runny nose 
and others.

Your electronic medical records will be accessed before surgery to ensure that you are eligible for the 
study, and members of the research team will gather sociodemographic (age, XXXX) and pertinent 
medical data, ensuring that any data that is collected is deidentified (removal of name, Date of birth, 
gender, address) and kept confidential. Your electronic medical records will also be accessed at 7 and 
30-day post-operative (after surgery) intervals to assess for any surgical site infections that may have 
occurred postoperatively.
What are the risks of harm or discomforts I might experience if I take part in this study?
The risks of this study are minimal except for minor discomfort from the nasal swabs. In rare cases, there 
may be some bleeding from the nares. In addition, as with any clinical trial, there is a risk of breach of 
patient confidentiality, though we do not expect this to occur.
Are there any benefits to me if I choose to take part in this study?
The benefits of taking part in this study may be decreased risk of surgical site infections. However, it is 
possible that you may not receive any direct benefit from taking part in this study. Your participation will 
contribute to medical knowledge.
What are my alternatives if I do not want to take part in this study?
There are no alternative treatments available. Your alternative is not to take part in this study.
How will I know if new information is learned that may affect whether I am willing to stay in the 
study?
During the study, you will be updated about any new information that may affect whether you are willing 
to continue taking part in the study. If new information is learned that may affect you after the study or 
your follow-up is completed, you will be contacted.
Will I receive the results of the research?
In general, we will not give you any individual results from the study. If we find something of urgent 
medical importance to you, we will inform you, although we expect that this will be a very rare occurrence.
Will there be any cost to me to take Part in this study?
There will not be any cost to you to take part in this study.
Will I be paid to take part in this study?
You will not be paid to take part in this study.
Who might benefit financially from this research?
Neither the university, the hospital, nor the investigators are expected to directly benefit financially from 
this research.
How will information about me be kept private or confidential?
All efforts will be made to keep your personal information in your research record confidential, but total 
confidentiality cannot be guaranteed. All data will be kept on encrypted and password-protected 
computers and transmitted only via secure means. The computers will be located in a secure area only 
accessible by the research team. The only identifying data that will be kept will be the medical record 
number and the date/type of procedure. The research team will only be using a separate ID number apart 
from the medical record number to identify data. These ID numbers will also ensure that subjects remain 
anonymous. The study will end after approximately 2 years and the data will be used in writing and 
publishing the manuscript, which will occur in the months following the end of the data collection period. 
The content will be published in a peer-reviewed scientific journal. Deidentified data will not be destroyed.

1.0 Research Design 
 
1.1 Purpose/Specific Aims 
To evaluate the efficacy and tolerability of 10% povidone-iodine in eliminating nasal carriage of S. 
aureus and MRSA. 
 
A.  Objectives  
To determine whether a more convenient, single-dose, pre-operative 10% povidone-iodine (PI) 
application is effective in reducing nasal carriage of S. aureus and MRSA. 
B.  Hypotheses / Research Question(s) 
We expect a statistically significant decrease in S. aureus/MRSA colonization in nasal cultures 
taken perioperatively after intervention in patients who received pretreatment with PI as compared 
to patients who received sterile saline. 
 
1.2 Research Significance 
 According to some estimates, as many as 25%-30% of healthy individuals in the community have nares 
colonized with S. aureus, while 1%-2.6% have MRSA-colonized nares[1]. This nasal carriage of S. aureus 
and MRSA is a known risk factor for post-operative wound infections in several different types of 
surgery[2]. Many, if not most infections due to S. aureus occur in colonized persons[1]. In implant-based 
breast reconstruction surgeries for instance, nasal carriers of S. aureus are 3 to 6 times more likely than 
noncarriers to develop nosocomial infections with this pathogen[3]. Similarly, studies have revealed that 
MRSA nasal colonization may be an independent risk factor for surgical site infection[4]. In a particular 
study, the MRSA PCR-positive group had a 9-fold increased risk of MRSA surgical site infection 
compared to the MRSA PCR-negative group, though the former had a low incidence at 1.86%[4]. 
Coagulase-negative staphylococci (CoNS) are also important etiological agents of post-operative 
infection[5, 6]. Together, S. aureus and CoNS (predominantly S. epidermidis, a common denizen of 
human skin that can colonize nares as well) account for 50-60% of prosthetic joint infections in roughly 
equal proportions[5, 6].
The agent typically used in assessing the effectiveness of nasal decolonization is mupirocin, which has 
been shown in some studies to eradicate colonization in up to 92% of post-operative nasal cultures[7]. 
Randomized controlled trials comparing nasal mupirocin with placebo in general, gynecologic, neurologic, 
orthopedic, and cardiothoracic procedures have demonstrated that mupirocin reduces the rate of surgical-
site infection among known carriers of S. aureus[2]. In fact, the American Society of Health-System 
Pharmacists recommends screening and nasal mupirocin decolonization for S. aureus-colonized patients 
before total joint replacement and cardiac procedures[8]. Likewise, some studies indicate that nasal 
mupirocin can decolonize CoNS, with only 1.3% of CoNS isolated from the nares of orthopedic surgery 
patients and 1.6% of samples from prosthetic joint infections displaying some resistance to mupirocin[5].
The mupirocin protocol for nasal decolonization discussed in the literature entails nasal application of 
mupirocin twice a day for 5 days before surgery[7]. Our end goal is to determine whether a more 
convenient, single-dose, pre-operative 10% povidone-iodine (PI) application can offer similar if not better 
surgical site infection results as mupirocin. The first step towards this goal is to evaluate the efficacy and 
tolerability of 10% povidone-iodine in eliminating nasal carriage of S. aureus and MRSA.
 
1.3 Research Design and Methods 
Implement povidone-iodine (10%) pre-operative nasal decolonization for patients undergoing same-day 
surgery and evaluate efficacy and tolerability of this intervention in eradicating nasal colonization.

Research Procedures 
This will be a prospective single-blinded randomized placebo-controlled trial of two applications of 
a nasal 10% PI solution used on the intranasal mucosal surfaces of each nostril in the preoperative 
holding area within 2 hours prior to surgical incision compared with sterile saline using the same 
technique. Both the PI and sterile saline will be applied by rotating the swab over the intranasal 
mucosal surface for 15 seconds; this process will be performed twice for both nostrils, using a new 
swab for each of the 4 applications.  200 subjects will be chosen from a pool of patients arriving at 
University Hospital, Newark, NJ for outpatient surgery. Inclusion criteria include community-based 
patients ages 18-80, ASA 1-3 who will be undergoing an outpatient surgery scheduled for at least 
1 hour and up to 6 hours duration. Exclusion criteria include pregnancy, allergy to povidone-iodine, 
infectious indication for surgery or preexisting known infection/wound, known immunocompromised 
state, use of antibiotics, chemotherapy, or steroids within 1 month prior to surgery. Additionally, 
patients presenting for surgeries where field avoidance prevents intraoperative access to the nares 
(e.g., ENT/OMFS/ophthalmology procedures) will be excluded. Patients will be randomly divided 
into two groups: control (sterile saline) vs. experimental (PI) This will be done via simple 
randomization using a computer program that assigns patients as they present into either the 
control or experimental group while maintaining an overall approximately even ratio of subjects in 
each group.

Potential subjects will be identified from surgical schedule. Patients will be asked for informed 
consent in the same-day surgery (SDS) unit. They will be given sufficient time to read the IC 
document and ask questions. While in the preoperative holding area, patients will be asked to sit 
upright at a 45-90° angle to prevent drainage into the nasopharynx. All patients will first be swabbed 
for a nasal swab specimen, once in each nostril. Patients will then receive the appropriate nasal 
applications depending on the group into which they were sorted: Povidone-Iodine or saline. The 
tolerability assessment of investigating drug will be done with every subject at the Pre-operating 
room and PACU by a few criteria as burning/itching, pain, irritation, epistaxis, runny nose, and 
others.  Nasal swab specimen will be obtained by the anesthesiologist intraoperatively 1, 2 and 3 
hours after investigational drug application as studies have shown that there a significant decrease 
in colony-forming units of MRSA even within 1-hour post-treatment [9, 10]. These cultures may be 
intraoperative or postoperative depending on the length of surgery. There will also be a nasal swab 
specimen obtained while the patient is in the PACU.  Study subjects will be stratified according to 
age, sex, comorbidities, and ethnicity. Additionally, the type of surgery, duration of surgery (Incision 
start to incision close), number of surgeons present during the procedure (Include all individuals 
scrubbed in), postoperative hospital stay length, and intraoperative time (patient in OR to patient 
out OR) will be used in data analysis. The purpose is to identify variables that increase the 
incidence of surgical site infection.
C.
Study Duration 
The study will take approximately 2 years, but chart review may continue up to 4 months after the 
last patient in the study has their procedure. Chart review of subject’s postoperative surgical clinic 
visits will be performed up to 30 days to monitor for any surgical site infection. 
D.
Endpoints 
The primary study end point is the decrease in S. aureus/MRSA colony forming units (CFU) in 
nasal swab specimen taken perioperatively after intervention in patients who presented with a 
positive pre-interventional nasal swab specimen. A secondary endpoint is the presence or absence 
of surgical site infections at 7 and up to 30-day postop intervals (per retrospective chart 
review). The review includes an assessment of post-operative infections, complications, and 
prescribing antibiotics (name, dose, number of days, completing).

Page 5 of 12
1.5 Sample Size Justification 
We assumed that S. aureus/MRSA suppression in 20% of patients would be clinically relevant and that 
up to 5% of patients may have suppression even without treatment. Using a one-sided alpha of 0.05 
and a beta of 80%, we calculated that we would need at least 85 patients in each group for a total of at 
least 170 patients. A paired t-test will be used to compare preintervention nasal culture CFUs to 1- hour 
post application, 2- hour post application, and 3-hour post application, nasal culture CFUs. A 2-sample 
t test will be used to compare the difference in pre- and post- intervention CFUs between the control 
and experimental groups at any endpoint. Additionally, mixed regression analysis will be used to 
determine the effect of the intervention on the CFU counts over all follow-up time points. 
 
1.6 Study Variables 
 
A.   Independent Variables, Interventions, or Predictor Variables  
Independent variable will be whether the patient received a nasal swab with Povidone-Iodine or 
sterile saline.
B.  Dependent Variables or Outcome Measures

6.1 Data Analysis 
We expect a statistically significant decrease in S. aureus/MRSA colonization in cultures taken 
perioperatively after intervention in patients who received pretreatment with PI as compared to patients 
who received sterile saline. We assumed that S. aureus/MRSA suppression in 20% of patients would 
be clinically relevant and that up to 5% of patients may have suppression even without treatment. Using 
a one-sided alpha of 0.05 and a beta of 80%, we calculated that we would need at least 85 patients in 
each group for a total of at least 170 patients. A paired t-test will be used to compare preintervention

nasal culture CFUs to 1- hour postintervention, 2- hour postintervention, and 3-hour postintervention 
nasal culture CFUs. A 2-sample t test will be used to compare the difference in pre- and post- 
intervention CFUs between the control and experimental groups at any endpoint. Additionally, mixed 
regression analysis will be used to determine the effect of the intervention on the CFU counts over all 
follow-up time points. 
 
The data will be stratified by type of surgery, duration of surgery, and number of surgeons present 
throughout the procedure.  Additionally, the variables age, sex, race, comorbidities, postoperative 
hospital stay length, and intraoperative time will be used in data analysis. In addition, postoperative 
surgical site infection (SSI) surveillance for the study participants will be conducted at 7 and 30-
day postop intervals. 
 
An intent to treat analysis will include those who are enrolled in the study and meet eligibility 
requirements for the study. A per protocol analysis will include all eligible patients who complete the 
assigned study regimen. Completion of the study regimen is defined as 2 applications of sterile saline 
or PI preoperatively and at least two cultures obtained perioperatively. 
 
 6.2 Data Security 
Clinical data for participants will be stored in REDCap. REDCap is a secure, web-based application. 
The server is located at Rutgers University and data is stored on secure networks behind a managed 
firewall. Data abstractors and clinical investigators will be the only ones who access to identified 
dataset. Other study members will only have access to data in aggregate or de-identified datasets.
Signed IC will be kept inside the locked cabinet
