DEVELOPMENT OF STEP-BY-STEP PROCEDURES
EVALUATION OF THE INFECTION CONTROL PROGRAM
After completing this chapter, the student should be able to do the following:
Describe the duties of an office safety coordinator.
Describe a mechanism to evaluate the office infection control program.
List the safety documents, policy statements, and records needed by a dental office.
Design a program to evaluate infection control in the office.
Describe the general nature of a checklist that can be used to organize and assess infection control procedures in the office.
Practicing infection control procedures, managing hazardous materials and regulated medical waste, and ensuring safety against fire and storms are referred to collectively as office safety. The office safety aspects of dentistry are expanding rapidly, with new and revised regulations and recommendations appearing frequently. New asepsis or other safety products and equipment continually appear on the market, and advances in research are bringing new concepts and approaches to controlling the spread of disease agents.
Today dental practices face the challenge of finding a way to maintain and implement an effective, efficient, and affordable office safety program.
Management of the multifaceted office safety program is facilitated if the employer identifies one person in the office to organize and supervise office safety. Such a safety coordinator works under the guidance of the employer and could be a hygienist or an assistant.
The safety coordinator must have a basic understanding of microbiology and the modes of disease spread in the office, infection control and other safety procedures, and products and equipment used with these procedures and also must know the related state and federal regulations. Extra training may be necessary at the time of initial assignment to the position, and continuing education is important so that the person can keep up with changes. The safety coordinator also should possess good written and verbal communication skills and good organizational skills and must be given time to perform the duties related to office safety.
Box 20-1 lists duties involved in managing the office safety program. Although the employer is responsible for all of these duties, most if not all can be delegated to the safety coordinator. Chapter 8 provides a review of steps for compliance with the Occupational Safety and Health Administration (OSHA) blood-borne pathogens standard.
The office safety coordinator and employer should develop a written personnel health program for the office workers that includes policies, procedures, and guidelines for education and training; immunizations; exposure prevention and postexposure management; medical conditions, work-related illness, and associated work restrictions; contact dermatitis and latex allergy; and maintenance of records, data management, and confidentiality.
Establishing written step-by-step procedures much like those presented in some chapters of this book helps ensure compliance and understanding of office safety procedures to be practiced. Writing down the steps allows proper organization of the procedures, documents their existence, and enhances learning by providing material that one may review periodically.
Chapter 17 gives an example of an overall clinical asepsis protocol that describes step-by-step procedures to be performed before seating the patient, during patient care, and after patient care. The protocol presented may not apply to all practices and should be changed to relate specifically to each office.
After reviewing all of the current regulations from local, state, and federal agencies, the office safety coordinator should maintain continuing education in this and related areas. The coordinator should establish contacts with or review educational material from organizations such as the American Dental Association, Organization for Safety and Asepsis Procedures, Centers for Disease Control and Prevention, American Dental Hygienists Association, American Dental Assistants Association, state dental associations, and a local school of dentistry (see Appendix A).
The Centers for Disease Control and Prevention recommendations are published in their own journal called Morbidity and Mortality Weekly Report (MMWR). Federal laws are published in the Federal Register; state laws are published in state registers. These publications are available in law schools and some public libraries, or one may obtain copies of regulations by contacting the respective federal or state agency (see Appendix A).
Office policies and procedures and details of regulations and compliance must be communicated periodically to members of the dental team during the required training on blood-borne pathogens and management of hazardous materials. Also, a key aspect of employee satisfaction is open communication among all members of the dental team. The entire team should participate in developing the total office safety program, and lines of communication should be established for constructive criticism and suggestions for improvement. An internal mechanism to resolve employee complaints is best.
Communication with patients regarding their safety while in the office is also important to establish trust and ensure return visits. Patients have varying degrees of knowledge about infection control and routes of disease spread. Today, patients are asking more and more questions about their safety in the office because of the news media coverage of issues in dentistry, such as the safety of amalgam fillings, the incident in Florida in which a dentist apparently infected six of his patients with human immunodeficiency virus in the late 1980s, and the concern about disease transmission through dental handpieces in the early 1990s, and more recently, contaminated dental unit water. These and other issues can erode public confidence in dentistry. Patients must be made aware of office procedures designed for their protection, many of which are conducted “behind the scenes.” Box 20-2 lists suggestions for instilling trust in patients regarding the care taken in the office for patient protection.
Documents and records must be prepared, maintained in proper form, and made readily available to dental team members (Box 20-3).
The office safety coordinator should develop mechanisms for rapid responses to body fluid exposures, hazardous material exposures, medical emergencies, fire, and storms. In relation to body fluid exposure, the procedure must involve a medical evaluation and follow-up as described in Chapter 8. The employer should maintain medical emergency kits, smoke alarms, and fire extinguishers; should identify an evacuation route in case of fire; and should identify procedures for protection in case of tornadoes, hurricanes, or earthquakes.
The employer should purchase, maintain, clean, and dispose of all products and equipment needed for infection control, management of hazardous materials, and other office safety procedures (Box 20-4). The costs of providing office safety can be difficult to recover; therefore, management of the supplies inventory, preventive maintenance of equipment, and avoiding of infection control overkill can be important.
Although adequate supplies need to be maintained, overstocking is a problem. Overstocking prolongs changing to another supply item of better quality or lower cost until current supplies have been used. The employer should evaluate products carefully and request samples before ordering and should let the entire dental team assist in the evaluation to ensure proper use when the item is purchased. The employer should make sure an item purchased will be appropriate for the desired use and should not purchase unproven substitutes or otherwise compromise appropriate quality for low cost. The employer should ensure that written and especially verbal claims about products have been documented appropriately with testing or peer-reviewed, published, scientific evaluation.
The employer should make sure that dental team members read, understand, and follow all labels and operating manuals for products and equipment. Misuse of products and equipment can lead to compromises in disease prevention or personal safety, damage to the equipment or surface related to product use, or damage to the equipment itself. Maintenance of equipment such as sterilizers, ultrasonic cleaners, vacuum traps, radiographic machines, smoke alarms, and fire extinguishers is particularly important so that they will work properly and have maximum use-life.
Periodically the employer should check and replace protective equipment such as utility gloves, eyewear, face shields, and reusable protective clothing when necessary. An inventory of all incoming chemicals ensures the availability of material safety data sheets and the presence of proper labels. The employer should ensure that disinfectants, sterilants, or other items with a specific shelf-life or use-life are replaced when indicated and should ensure that sharps containers are located where needed and that they are replaced before they overflow.
Examples of infection control overkill that can be time-consuming and costly are routinely hand scrubbing and ultrasonically cleaning instruments, routinely cleaning and disinfecting surfaces after removal of surface covers, using more than one layer of sterilization wrap during packaging, routinely disinfecting instruments before sterilization, using thick rather than thin plastic as surface covers, using sterile gloves for routine procedures, and using special disposal mechanisms for items that are not considered as regulated medical waste.
Evaluation of the office infection control program is an effective way to improve procedures so they are useful, feasible, ethical, and accurate. A successful evaluation program depends on the following:
• Developing standard operating procedures
The strategies used for the evaluation include the use of checklists to document that procedures are in place (see the following discussion), documentation that written procedures are in place and are available to all in the office, and direct observation of work activity to make sure procedures are performed correctly. One should take care about the validity of passive evaluation procedures such as second-hand verbal information obtained from staff interviews. Direct observation and documentation are usually more reliable. Six suggestions on how to determine the effectiveness of an infection control program are given in Table 20-1. The CDC has provided some examples of procedures one could evaluate in the office and how to evaluate them in Table 20-2.
TABLE 20-1
Measure the Effectiveness of an Infection Control Program
Desired Outcomes | Examples to Measure |
1. Infection control procedures have been learned | Has appropriate training occurred? |
2. The office is assessing up-to-date infection control information | Is the office following the 2003 CDC infection control guidelines? |
3. Infection control procedures are being performed correctly | Does surface asepsis include precleaning prior to disinfection? |
4. Appropriate infection control products and equipment are being used | Is the surface disinfectant used to clean up visible blood and saliva an intermediate-level disinfectant? |
5. The particular infection control product or equipment is being used correctly | Does the timing of the dry heat sterilizer start after the unit has reached the sterilizing temperature? |
6. The office infection control program is compliant with laws and recommendations | Is the OSHA-required annual infection control training provided to all staff? |

TABLE 20-2
Examples of What to Evaluate in a Dental Office Infection Control Evaluation Program
What to Evaluate | How to Evaluate |
Immunizations of the office staff | Conduct an annual review of staff records to ensure up-to-date immunizations. |
Occupational exposures to infectious materials | Report the exposures. Document and review the steps that occurred around the exposure and plan how it could be prevented in the future. |
Postexposure management and follow-up | Ensure the postexposure management plan is understood by all office staff and that the exposure evaluation procedures are available at all times. |
Hand hygiene procedures | Observe and document circumstances of appropriate and inappropriate hand hygiene. Review findings in a staff meeting. |
Use of personnel protective barriers | Observe and document the use of barrier precautions and careful handling of sharps. Review findings in a staff meeting. |
Monitoring the sterilization process | Compare the paper log of mechanical monitoring (time/temperature) and chemical monitoring (temperature strips) of each sterilizer load with the weekly biologic monitoring (spore testing) results. Document that appropriate procedures are in place and are performed when sterilization failure occurs. |
Evaluating safety devices | Conduct an annual review of the exposure control plan for documentation of new developments in safety devices. |
Microbial quality of dental unit water | Monitor the microbial content of water exiting the dental units to determine compliance with the Environmental Protection Agency drinking water standard of no more than 500 CFU/mL of heterotrophic bacteria. |
Preparation of standard operating procedures will document the correct way of doing something. Direct observation of work activity ensures that the dental team understands how properly to perform procedures and use equipment. Problems with compliance may indicate that further training is needed. The person performing a procedure may use a checklist when direct observation is not possible.
