A five-year study of needlestick injuries: significant reduction associated with communication, education, and convenient placement of sharps containers.

OBJECTIVE: To decrease the numbers of needlesticks among healthcare workers. DESIGN: All reported needlestick injuries at Santa Clara Valley Medical Center, San Jose, California, were reviewed, analyzed, and tabulated by the infection control department yearly from 1986 to 1990. SETTING: A 588-bed county teaching hospital in San Jose, California, affiliated with Stanford University. PARTICIPANTS: All employees of Santa Clara Valley Medical Center who reported needlestick injuries on injury report forms. INTERVENTIONS: From April to December 1987, more needle disposal containers were added to as many patient care areas and as close to the area of use as possible. Results of 1986, 1988, 1989, and 1990 analyses were communicated yearly to all personnel, extensive educational programs were conducted in 1987 and 1988, and educational efforts continued in 1989 and 1990. RESULTS: In 1986, there were 259 needlestick injuries at our institution, 22% (32) from recapping. After needle disposal containers were added to all patient care areas, needlestick injuries for 1988 totalled 143, a 45% decrease in the total needlestick injuries and a 53% decrease in recapping injuries. Communication of results to all areas of the hospital and educational activities were started in 1987 and continued through the next 3 years. In 1989, there were 135 needlestick injuries, a decrease of 6% from 1988; recapping injuries decreased 40% from 1988. In 1990, there were 104 needlestick injuries, a 23% decrease since 1989, and a 33% decrease in recapping injuries. The total number of needlestick injuries from 1986 to 1990 decreased by 60%, and those injuries from recapping decreased by 81% to 89%. CONCLUSIONS: We have continued to monitor needlestick injuries, communicate findings to all personnel, and include needlestick prevention in educational programs. We contend that more convenient placement of needle disposal containers, communication of findings, and education do decrease needlestick injuries in healthcare workers.

Standardized management of patients and employees exposed to pertussis.

Waning pertussis immunity and spread of pertussis by asymptomatic adults contributes to increased pertussis exposures of vulnerable children. The Santa Clara Valley Medical Center had 49 pertussis exposures between July 1, 1989, and June 30, 1997, which originated in pediatric units or clinics and had an impact on the Employee Health Service (EHS) and Emergency Department (ED). We have developed a standardized protocol for management of employees and patients exposed to pertussis. The protocol includes a checklist for infection control staff; memoranda to exposed units conveying exposure information, instructions for employees to report to EHS or ED, and disease symptom information; written guidelines for physician management of patient exposures (prophylaxis and isolation) and EHS or ED management of employee exposures; and prophylaxis recommendations. We allow exposed employees to work while wearing a mask (worn until 5 days of prophylaxis are completed or for the entire potential contagious period if prophylaxis was refused). Employees who develop pertussis are restricted from work. Our protocol and standardized forms provide consistent management of pertussis exposures in both patients and employees.

Azithromycin prophylaxis during a hospitalwide outbreak of a pertussis-like illness.

A questionnaire regarding tolerability and adherence was administered for 5 days to hospital employees who received azithromycin prophylaxis during a hospitalwide outbreak of a pertussis-like illness. Analysis of the 239 responses from those having received prophylactic azithromycin determined that it was well tolerated and accounted for a minimal loss of days worked; 81.5% were fully adherent with the regimen.

Percutaneous injury analysis: consistent categorization, effective reduction methods, and future strategies.

OBJECTIVE: To report the results of an 8-year analysis of percutaneous injuries (PI), to describe interventions to decrease these injuries, and to discuss future prevention strategies. DESIGN: Using consistent methods, 881 percutaneous injury reports were reviewed, categorized, and analyzed from 1986 through 1993. SETTING: A 620-bed acute-care county teaching hospital located in San Jose, California, that is affiliated with Stanford University Medical School, Palo Alto, California. PARTICIPANTS: Employees of Santa Clara Valley Medical Center who reported percutaneous injuries from 1986 through 1993. INTERVENTIONS: Placement of needle disposal containers in all patient care areas, 1987; education, 1987 to present; communication of percutaneous injury analyses to all departments, 1988 to present; and safety product evaluation and purchases, 1991 to present. RESULTS: The total number of PI decreased by 65% (P = .0007) from 1986 through 1993. Recapping injuries decreased from 1986 through 1993 by 88% (P < .0002); interventions that included convenient placement of needle disposal containers and consistent annual education may have contributed to this decrease. Injuries from manipulating intravenous lines or heparin locks decreased in 1992 (P < .03) after purchase of a needleless system for intravenous lines. Injuries from improper disposal or from abrupt patient movement did not decrease significantly over the 8-year period. CONCLUSIONS: This institution has conducted percutaneous injury analysis for 8 years, utilizing consistent reviewers and categorization methods. Successful interventions have reduced recapping injuries, injuries from manipulating intravenous lines/heparin locks, and the overall numbers of PI. The categories of "Improper Disposal" and "Patient Moved Abruptly" present challenges for future reductions, as well as the recently identified problem of staff not using available safety devices or using them improperly.

Safety product evaluation: six years of experience.

Safety products to prevent percutaneous injuries are rapidly being developed for health care. Decisions to purchase such products are often made by an institution's infection control committee. We evaluated 30 safety products. These products are most readily accepted when potential users perceive a need, believe they are at risk for injury, and have input into the selection process. Task forces of intended users are invaluable in determining which products to evaluate in high-risk areas. Some new devices may be unsafe if excessive manipulation or in-service education is required. New products may not be well accepted if the devices are a different size or configuration than usual or require changes in established practices or techniques. An adequate supply of new products must be available immediately when the evaluation begins or users will tend to select the older, more familiar product. Removing all similar devices except for the new product can facilitate acceptance. Frequency of use can also influence employees when trying a new product. For instance, nurses who only occasionally draw blood have different perceptions of a new blood-drawing device from those of the phlebotomy team. Key employees were designated as resource persons to complement the manufacturer's in-service education and to support transition to the new product. We recommend that decision making by infection control committees involve the individuals who will eventually directly use the new products, starting with the early phases of safety product evaluation.

A survey of percutaneous/mucocutaneous injury reporting in a public teaching hospital.

Our objective was to determine if healthcare workers were reporting all percutaneous and/or mucocutaneous injuries and to use such data to formulate appropriate interventions. The Infection Control Department distributed anonymous surveys of healthcare personnel between 1992 and 1995. The elicited information included the number of percutaneous and mucocutaneous injuries experienced and reported in the last five years and the reasons for not reporting every exposure when applicable. Five hundred and forty nine surveys were received, from physicians, dentists, registered nurses, licensed vocational nurses, nurses aides, and operating room technicians. Overall, of the 549 respondents, 45% (245) had no injuries, 30% (163) had been injured and had reported all injuries, and 26% (141) had not reported all injuries. Reasons for not reporting included sterile/clean needlestick (39%), little or no perception of risk to employee (26%), too busy (9%), and dissatisfaction with follow-up procedures (8%). Reasons stated for not reporting injuries indicate a need for continued education in the risk of acquiring blood-borne pathogens from such injuries. The results also illustrate the importance of targeting prevention efforts to specific groups, such as physicians, that would not be identified by routine reporting mechanisms.

Planning a hepatitis C postexposure management program for health care workers. Issues and challenges.

1. Approximately 4 million individuals in the United States are infected with hepatitis C virus (HCV), many of whom are unaware of this infection. Thus, health care workers are faced with the potential for needlestick and blood exposure to another bloodborne pathogen in addition to hepatitis B and HIV. 2. The Centers for Disease Control and Prevention recommended that health care facilities follow guidelines from the U.S. Public Health Service for prevention and control of HCV infection. 3. Hospitals and other health care institutions must consider legal, ethical, and health issues and outcomes when formulating a comprehensive postexposure program for hepatitis C. 4. The occupational health professional can play an integral role in both postexposure management and prevention of HCV exposures in the health care setting.
