Health workers need influenza immunization

APIC calls for increase in low rates

In response to the unacceptably low influenza immunization rates among health care workers, the Association for Professionals in Infection Control and Epidemiology (APIC) issued specific recommendations to health care facilities to develop and implement comprehensive influenza vaccination programs for employees.

APIC is a nonprofit professional association composed of more than 10,000 members whose responsibility is the prevention and control of infections and related adverse outcomes in patients and health care workers. APIC’s new recommendations were published in the May issue of the American Journal of Injection Control. (For the highlights of the recommendations, see box, below.)

Recommendations for Health Facilities’ Immunizations

APIC recommends that all health care facilities develop and implement comprehensive influenza vaccination programs for employees. Highlights of APIC’s new recommendations include:

  • Prepare a written policy stressing the need and importance of annual influenza vaccination annually for health care workers.
  • Implement influenza immunization programs annually, including health care worker education on influenza vaccination.
  • Monitor annual immunization rates and providing feedback regarding program success.
  • Increase access to vaccination by removing associated costs and making vaccine easily accessible.
  • Facilitate administration of vaccination to health care workers in all settings.

Only 36% of health care workers receive an annual influenza vaccination despite long-standing recommendations by the Centers for Disease Control and Prevention (CDC) and other organizations. Health care workers are at high risk for acquiring influenza infection due to their exposure to ill patients as well as their exposure in the community. Health care workers are defined here as all personnel who have contact with patients, both medical and nonmedical, because when these staff are infected with influenza, they can spread the virus to patients in their care.

Research, in fact, suggests health care workers can be a key source of institutional outbreaks, contributing to increased morbidity and mortality among vulnerable patients.

"Greater emphasis needs to be placed on improving influenza immunization rates among health care workers to help ensure patient safety and protection — especially for patients at increased risk of influenza-related complications," said Jeanne A. Pfeiffer, RN, MPH, CIC, APIC president.

"Immunization also provides personal protection for health care workers and minimizes work force absenteeism during the influenza season," she explained.

Health care workers encounter patients throughout the influenza season in a variety of settings, including medical practices, general hospitals, specialty hospitals, pediatric hospitals, long-term care facilities, emergency departments, ambulatory care settings, rehabilitation facilities and home care sites.

Studies show health care workers are more likely to work through illness and return to work sooner when they are ill, thus increasing the likelihood of virus transmission to patients in their care and co-workers.

In addition, institutional influenza outbreaks can have serious implications for both the patient and health care provider. These events can put patients at risk, result in or exacerbate existing staff shortages, curtail admissions, and increase health care costs.

Vaccination is the primary means of reducing influenza transmission and preventing infection from the influenza virus. Each year, the infection causes an average of 36,000 deaths and 114,000 hospitalizations in the United States.

"Health care facilities have an important role to play in maximizing influenza vaccination rates in health care workers," Pfeiffer said. "Every facility should develop and implement comprehensive influenza vaccination programs for employees."

APIC initiated a multifaceted initiative in January 2004 aimed at increasing influenza immunization rates among health care workers. As a result, APIC is completing a membership survey to assess the state of employee influenza immunization programs at members’ institutions across the country.

In addition, APIC is developing new resources for infection control professionals and other health care providers that will help encourage institutions to implement formal influenza control policies.

APIC’s initiative, including the survey results and new professional resources, will be highlighted at its 31st Annual Educational Conference in Phoenix, June 9, 2004.
