Microwave ovens produce radio-frequency waves that cause the water molecules in an object to vibrate. This vibration causes friction, which allows the object to heat up to a temperature that can kill germs.

That's why microwaves are sometimes used to disinfect items such as a household sponge, as they are a hotbed for viruses and bacteria.

However, research has found mixed results on whether a microwave can effectively kill germs on a sponge, or even in food. Here's what you need to know.

Tim Landers, PhD, RN, CNP, CIC, associate professor at The Ohio State University College of Nursing and chair of the Association for Professionals in Infection Control and Epidemiology (APIC) Research Committee is co-author of the article, “APIC MegaSurvey: Methodology and overview,” recently published in the American Journal of Infection Control (AJIC). This article is the first in a series based on findings from the APIC MegaSurvey. Results from the APIC MegaSurvey, the largest-ever survey of the infection-prevention workforce, describe the core activities and competencies of infection preventionists (IPs). 

APIC undertook the MegaSurvey in 2015 to create a baseline of data to answer critical questions related to practice and competencies, organizational structure and staffing, compensation and the demographics of IPs. IPs are experts in identifying sources of infections and limiting their transmission in healthcare facilities.

“Infection preventionists are the backbone of efforts to prevent infections in healthcare settings,” said Landers. “Despite increasing recognition of the importance of infection prevention, relatively little is known about contemporary IP practice. To provide resources to support IPs and identify future directions for infection prevention, APIC felt it was critical to understand IPs’ current practice environments.”

Results from the APIC MegaSurvey will allow for a better understanding of IP roles and responsibilities by facility type, years of experience, professional development and current position, and will provide insight into opportunities for professional development.

Of 13,050 eligible APIC members, 4,078 (31 percent) took the online survey in mid- to late 2015. Among the key findings: 

  • The majority of respondents (81 percent) have a primary discipline of nursing.
  • Two-thirds of IPs (66.2 percent) currently work in acute-care settings; the remaining portion work in long-term care, ambulatory, outpatient and other care settings.
  • Surveillance and investigation were reported as the most frequent activities by IPs, accounting for a quarter (25.4 percent) of infection prevention efforts.
  • Forty-three percent of respondents are certified in infection prevention and control (CIC).
  • More than 37 percent are not certified, but indicate they plan to sit for certification in the future.
  • Individuals with current CIC certification had higher base compensation than those without current certification.

“The APIC MegaSurvey data establishes a benchmark for practice and compensation data, and suggests directions for future growth of the IP role,” Landers said. “Forthcoming articles, developed by the APIC Research Committee, will provide in-depth analyses of the data to frame IP practice for the coming years.”

One of the upcoming articles that will be of most interest to IPs will address staffing levels, organization and support of infection prevention and control programs. Additional articles will cover IP compensation, expansion of the IP workforce to include professionals with non-clinical backgrounds, roles and responsibilities of IPs working outside of the acute-care (hospital) setting and strategies to support certification.

In 2016, APIC published a Compensation Report based on MegaSurvey data. Additional reports on practices and competencies, and organizational structure will be released in March.

APIC MegaSurvey: Methodology and overview,” by Timothy Landers, James Davis, Katrina Crist, and Charu Malik appears in the American Journal of Infection Control, Article in press.


The American Journal of Infection Control ( covers key topics and issues in infection control and epidemiology. Infection preventionists, including physicians, nurses and epidemiologists, rely on AJIC for peer-reviewed articles covering clinical topics as well as original research. As the official publication of APIC, AJIC is the foremost resource on infection control, epidemiology, infectious diseases, quality management, occupational health and disease prevention. AJIC also publishes infection control guidelines from APIC and the CDC. Published by Elsevier, AJIC is included in Medline and CINAHL.


APIC’s mission is to create a safer world through prevention of infection. The association’s more than 15,000 members direct infection-prevention programs that save lives and improve the bottom line for hospitals and other healthcare facilities. APIC advances its mission through patient safety, implementation science, competencies and certification, advocacy and data standardization.

Timothy F. Landers, PhD, CNP, assistant professor at The Ohio State University College of Nursing, is one of just 12 outstanding nursing educators to win a competitive grant from the Robert Wood Johnson Foundation (RWJF) Nurse Faculty Scholars program this year. Landers will receive a three-year, $350,000 award to promote his academic career and support his research. The Nurse Faculty Scholar award is given to junior faculty who show outstanding promise as future leaders in academic nursing.

“The mentoring, guidance and financial support from the Robert Wood Johnson Foundation will allow me to develop and test a protocol aimed at improving hand hygiene among hospitalized patients,” Landers said.

Although hand hygiene is widely recognized as the most important means of preventing infection, relatively little work has been done to encourage patients to clean their own hands. In this study, Landers is investigating the five most common bacteria causing healthcare-associated infections (HAIs) to see if improving patient hand hygiene reduces these bacteria. Bacteria present on the skin of patients cause a majority of HAIs.

“In other words, the goal of this research is to show that our mothers were right – washing your hands is an important part of staying healthy,” Landers continued. “When patients are acutely ill, there are often other priorities besides keeping our hands clean.”

This study follows the publication of a large analysis of scientific data on the benefits of patient hand hygiene by patients in the American Journal of Infection Control by Landers and colleagues in May 2012. “When talking with infection control professionals, patient hand hygiene is recognized as an important topic, but one that has not been addressed,” Landers added. “It is my hope that we can develop an evidence-based protocol for when and how patients should clean their hands to reduce infections.”

Landers’ mentors for this work are Donna McCarthy, RN, PhD, FAAN, professor and associate dean for research at the College of Nursing; and Kurt Stevenson, MD, MPH, associate professor, internal medicine, and associate director of clinical epidemiology at the Ohio State Wexner Medical Center.

The RWJF Nurse Faculty Scholars program is strengthening the academic productivity and overall excellence of nursing schools by developing the next generation of leaders in academic nursing. It is providing $28 million to five cohorts of outstanding junior nursing faculty. Landers is part of the fifth cohort.

“Tim is an outstanding Buckeye faculty member who engages in cutting-edge research and innovative teaching,” said Bernadette Melnyk, PhD, RN, CPNP/PMHNP, FNAP, FAAN, dean of the College of Nursing and chief wellness officer at Ohio State.He is so deserving of this prestigious award.”

The new Nurse Faculty Scholars will also support the Future of Nursing: Campaign for Actionwhich is engaging nurses and others in a nationwide effort to implement recommendations from the groundbreaking Institute of Medicine report "The Future of Nursing: Leading Change, Advancing Health."

Supporting junior nurse faculty will help curb a shortage of nurse educators that could undermine the health and healthcare of all Americans. The Affordable Care Act will vastly increase the number of people who can access healthcare in the United States. As the number of patients increases, there will be greater demand for skilled nurses as well as faculty to educate them. Right now, many schools of nursing are turning away qualified applicants because they do not have the faculty to teach them. The RWJF Nurse Faculty Scholars program is helping more junior faculty succeed in and commit to academic careers. The program will also enhance the stature of the scholars’ academic institutions, which will benefit fellow nurse educators seeking professional development opportunities.

To receive the award, scholars must be registered nurses who have completed a research doctorate in nursing or a related discipline and who have held a tenure-eligible faculty position at an accredited nursing school for at least two and no more than five years.

The Nurse Faculty Scholars program is funded by the RWJF and administered through the Johns Hopkins University School of Nursing. It is directed by Jacquelyn Campbell, PhD, RN, FAAN, who is the Anna D. Wolf chair and professor at the Johns Hopkins University School of Nursing.
