Issues in understanding the impact of the Needlestick Safety and Prevention Act on hospital sharps injuries.

OBJECTIVE: Measuring the effect of the Needlestick Safety and Prevention Act (NSPA) is challenging. No agreement exists on a common denominator for calculating injury rates. Does it make a difference? How are the law and safety-engineered devices related? What is the effect on injuries and costs? This study examines those issues in assessing the impact of the legislation on hospital worker percutaneous injuries. METHODS: Using a historic prospective design, we analyzed injury data from 85 hospitals. Injury rates were calculated per 100 full-time equivalents, 100 staffed beds, and 100 admissions each year from 1995 to 2005. We compared changes for each denominator. We measured the proportion of the injury rate attributed to safety-engineered devices. Finally, we estimated a national change in injuries and associated costs. RESULTS: For all denominators, a precipitous drop in injury rates of greater than one-third ([Formula: see text]) occurred in 2001, immediately following the legislation. The decrease was sustained through 2005. Concomitant with the decrease in rates, the proportion of injuries from safety-engineered devices nearly tripled ([Formula: see text]) across all denominators. We estimated annual reductions of more than 100,000 sharps injuries at a cost savings of $69-$415 million. CONCLUSIONS: While the data cannot demonstrate cause and effect, the evidence suggests a reduction in hospital worker injury rates related to the NSPA, regardless of denominator. It also suggests an association between the increase in safety-engineered devices and the reduction in overall injury rates. The decreases observed translate into significant reductions in injuries and associated costs.

Chinks in the armor: activation patterns of hollow-bore safety-engineered sharp devices.

A retrospective review of secondary injury data was used to evaluate the characteristics of percutaneous injuries from safety-engineered sharp devices. Injury rates and safety device activation rates differed by healthcare provider type. Approximately 22.8%-32% of injuries could have been prevented had an available safety feature been activated after use.

Risk of bloodborne pathogen exposure among Zambian healthcare workers.

PURPOSE: Understanding the risks of bloodborne pathogen transmission is fundamental to prioritizing interventions when resources are limited. This study investigated the risks to healthcare workers in Zambia. DESIGN: A survey was completed anonymously by a convenience sample of workers in three hospitals and two clinics in Zambia. Respondents provided information regarding job category, injuries with contaminated sharps, hepatitis B vaccination status and the availability of HIV post-exposure prophylaxis (PEP). RESULTS: Nurses reported the largest number of injuries. The average annual sharps injury rate was 1.3 injuries per worker, and service workers (housekeepers, laundry, ward assistants) had the highest rate of these injuries, 1.9 per year. Injuries were often related to inadequate disposal methods. Syringe needles accounted for the largest proportion of injuries (60%), and 15% of these injuries were related to procedures with a higher-than-average risk for infection. Most workers (88%) reported the availability of PEP, and only 8% were fully vaccinated against hepatitis B. CONCLUSIONS: The injury risks identified among Zambian workers are serious and are exacerbated by the high prevalence of bloodborne pathogens in the population. This suggests that there is a high risk of occupationally acquired bloodborne pathogen infection. The findings also highlight the need for a hepatitis B vaccination program focused on healthcare workers. The risks associated with bloodborne pathogens threaten to further diminish an already scarce resource in Zambia - trained healthcare workers. To decrease these risks, we suggest the use of low-cost disposal alternatives, the implementation of cost-sensitive protective strategies and the re-allocation of some treatment resources to primary prevention.

Practice of universal precautions and risk of occupational blood-borne viral infection among Congolese health care workers.

The extent of occupational injuries among health care workers in central Africa, particularly in the Democratic Republic of Congo, is not documented. We sought to determine the incidence of percutaneous injury and exposure to blood and other body fluids in Congolese urban and rural hospitals in the previous year. Our data show high rates of percutaneous injury and exposure to blood and other body fluids, reflecting poor safety conditions for most Congolese health care workers.

Disposal of sharps medical waste in the United States: impact of recommendations and regulations, 1987-2007.

BACKGROUND: To gauge the impact of regulatory-driven improvements in sharps disposal practices in the United States over the last 2 decades, we analyzed percutaneous injury (PI) data from a national surveillance network from 2 periods, 1993-1994 and 2006-2007, to see whether changes in disposal-related injury patterns could be detected. METHODS: Data were derived from the EPINet Sharps Injury Surveillance Research Group, established in 1993 and coordinated by the International Healthcare Worker Safety Center at the University of Virginia. For the period 1993-1994, 69 hospitals contributed data; the combined average daily census for the 2 years was 24,495, and the total number of PIs reported was 7,854. For the period 2006-2007, 33 hospitals contributed data; the combined average daily census was 6,800, and the total number of PIs reported was 1901. RESULTS: In 1992-1993, 36.8% of PIs reported were related to disposal of sharp devices. In 2006-2007, this proportion was 19.3%, a 53% decline. CONCLUSIONS: This comparison provides evidence that implementation of point-of-use, puncture-resistant sharps disposal containers, combined with large-scale use of safety-engineered sharp devices, has resulted in a marked decline in sharps disposal-related injury rates in the United States. The protocol for removing and replacing full sharps disposal containers remains a critical part of disposal safety.

Benchmarking of percutaneous injuries at a teaching tertiary care center in Saudi Arabia relative to United States hospitals participating in the Exposure Prevention Information Network.

BACKGROUND: Despite recent improvements in policies, practices, and device design, percutaneous injuries (PIs) from needles and sharp instruments continue to expose health care workers to the risk of bloodborne pathogens. METHODS: Prospective surveillance was instituted to study the epidemiologic characteristics of PIs at King Abdulaziz Medical City, Riyadh, Saudi Arabia (KAMC-R) from 2004 through 2008 and to benchmark these characteristics relative to those of a network of US hospitals participating in the Exposure Prevention Information Network (EPINet) research group (2004-2007). RESULTS: The mean PIs rate per 100 daily occupied beds in KAMC-R was significantly lower than that reported by teaching and nonteaching US EPINet hospitals. Similar to US EPINet hospitals, nurses at KAMC-R reported more PIs than physicians. Compared with US EPINet hospitals, nurses at KAMC-R experienced more PIs (52.8% vs 38.1%, respectively), whereas physicians experienced fewer PIs (18.4% vs 28.6%, respectively). The majority of PIs happened in patient wards (50.6%) in KAMC-R and operating rooms (34.1%) in US EPINet hospitals. Suturing, which was involved in only 10% of PIs at KAMC-R, was the most frequent PIs mechanism in US EPINet hospitals (23.3%). In both KAMC-R and US EPINet hospitals, disposable syringes were the most frequent devices involved, the left hand was the most common site of injury, and the source patient was largely identifiable. CONCLUSION: We have lower rates of PIs at KAMC-R relative to US EPINet hospitals. Whereas it is difficult to fully explain such differences, this could be due to variations in health care systems, underreporting, or the impact of the PIs prevention activities.

Increase in sharps injuries in surgical settings versus nonsurgical settings after passage of national needlestick legislation.

BACKGROUND: The operating room is a high-risk setting for occupational sharps injuries and bloodborne pathogen exposure. The requirement to provide safety-engineered devices, mandated by the Needlestick Safety and Prevention Act of 2000, has received scant attention in surgical settings. STUDY DESIGN: We analyzed percutaneous injury surveillance data from 87 hospitals in the United States from 1993 through 2006, comparing injury rates in surgical and nonsurgical settings before and after passage of the law. We identified devices and circumstances associated with injuries among surgical team members. RESULTS: Of 31,324 total sharps injuries, 7,186 were to surgical personnel. After the legislation, injury rates in nonsurgical settings dropped 31.6%, but increased 6.5% in surgical settings. Most injuries were caused by suture needles (43.4%), scalpel blades (17%), and syringes (12%). Three-quarters of injuries occurred during use or passing of devices. Surgeons and residents were most often original users of the injury-causing devices; nurses and surgical technicians were typically injured by devices originally used by others. CONCLUSIONS: Despite legislation and advances in sharps safety technology, surgical injuries continued to increase during the period that nonsurgical injuries decreased significantly. Hospitals should comply with requirements for the adoption of safer surgical technologies, and promote policies and practices shown to substantially reduce blood exposures to surgeons, their coworkers, and patients. Although decisions affecting the safety of the surgical team lie primarily in the surgeon's hands, there are also roles for administrators, educators, and policy makers.

The national study to prevent blood exposure in paramedics: rates of exposure to blood.

OBJECTIVE: The purpose of this analysis is to present incidence rates of exposure to blood among paramedics in the United States by selected variables and to compare all percutaneous exposure rates among different types of healthcare workers. METHODS: A survey on blood exposure was mailed in 2002-2003 to a national sample of paramedics. Results for California paramedics were analyzed with the national sample and also separately. RESULTS: The incidence rate for needlestick/lancet injuries was 100/1,000 employee-years [95% confidence interval (CI), 40-159] among the national sample and 26/1,000 employee-years (95% CI, 15-38) for the California sample. The highest exposure rate was for non-intact skin, 230/1,000 employee-years (95% CI, 130-329). The rate for all exposures was 465/1,000 employee-years (95% CI, 293-637). California needlestick/lancet rates, but not national, were substantially lower than rates in earlier studies of paramedics. Rates for all percutaneous injuries among paramedics were similar to the mid to high range of rates reported for most hospital-based healthcare workers. CONCLUSIONS: Paramedics in the United States are experiencing percutaneous injury rates at least as high as, and possibly substantially higher than, most hospital-based healthcare workers, as well as substantially higher rates of exposure to blood on non-intact skin.

Chinese EPINet and recall rates for percutaneous injuries: an epidemic proportion of underreporting in the Taiwan healthcare system.

OBJECTIVES: As an occupational injury, percutaneous injury (PI) can result in chronic morbidity and death for healthcare workers (HCWs). A pilot surveillance system for PIs using the Chinese version of Exposure Prevention Information Network (EPINet) was introduced in Taiwan in 2003. We compared data from EPINet and recall of PIs using a cross-sectional survey for rates to establish the reliability of the new system. METHODS: HCWs from hospitals that had implemented EPINet for > or =12 months completed a survey for recall of contaminated PIs sustained between October 2004 and September 2005, type of item involved, and reasons for reporting or not reporting the PI. Comparative data from EPINet for the same period were analyzed. RESULTS: The EPINet rate, 36.1/1,000 HCW (95%CI 31.8-41.1) was almost 5 times lower (p<0.0001) than the PI recall rate for 2,464 HCWs of 170/1,000 HCWs (95%CI 155.4-185.5). Approximately 2.5 PIs were recalled for every 1,000 bed-days of care. The recall rate by physicians was 268.3/1,000, 188.5/1,000 for nurses, 88.9/1,000 for medical technologists and 81.3/1,000 for support staff. Hollow-bore needle items most commonly recorded on EPINet includ, disposable needles and syringes were underreported by 81%, vacuum tube holder/needles by 67%, and arterial blood gas needles by 75%. Nearly 63% of the reasons for underreporting were related to the complexity of the reporting process, while 37% were associated with incorrect knowledge about the risks associated with PIs. CONCLUSIONS: EPINet data underestimates a commonplace occupational injury with nearly four in five PIs not reported. Addressing the real barriers to reporting must begin with hospital administrators impressing on HCWs that reporting is essential for designing appropriate safety interventions.

Provision and use of personal protective equipment and safety devices in the National Study to Prevent Blood Exposure in Paramedics.

BACKGROUND: Paramedics are at risk for human immunodeficiency virus, hepatitis B virus, and hepatitis C virus infection from occupational blood exposure. This study examined how often paramedics are provided with personal protective equipment (PPE), sharps containers, and selected safety devices by their employers; the frequency with which paramedics use sharps containers and these safety devices; and paramedics' attitudes regarding this equipment. METHODS: We conducted a mail survey among a nationally representative sample of certified paramedics. California was oversampled to allow for separate estimation of proportions for this population. RESULTS: The final sample included 2588 paramedics, 720 of whom were from California (adjusted response rate, 55%). Paramedics in California were provided safety devices more often than paramedics in the United States as a whole. For each type of device, there was at least a 40% increase in use when the device was always provided compared with when it was not always provided. Eighty-four percent of paramedics thought that safety needles significantly reduce blood exposure, but substantial percentages thought that safety needles, eye protection, and masks interfere with some medical procedures. Approximately one fifth said that they need more training in the use of safety devices and PPE. CONCLUSION: Lack of access to safety devices is the major barrier to their use, and the higher rates of provision and use in California may be the result of the state's early safety needle legislation. Increased provision, training, and improvement of safety equipment are needed to better protect paramedics from blood exposure.

National incidence of percutaneous injury in Taiwan healthcare workers.

We established a standardized surveillance system using the Chinese Exposure Prevention Information Network to estimate the frequency of percutaneous injuries (PCIs) in Taiwanese healthcare workers (HCWs). Fourteen hospitals employing 8,132 HCWs participated and a total of 583 PCIs were reported. The annual number was estimated to be 8,058 PCIs per hospital size, 8,100 per HCWs, and 8,286 per inpatient-day; indicating similar estimates using different denominators. The estimated annual frequency of pathogen-specific PCIs was 1,168 for hepatitis B, 1,263 for hepatitis C, and 59 for HIV. This study documents the annual incidence of PCI among HCWs showing important potential exposure to viral hepatitis and HIV in Taiwan.

The national study to prevent blood exposure in paramedics: exposure reporting.

BACKGROUND: This survey was conducted to provide national incidence rates and risk factors for exposure to blood among paramedics. The present analysis assesses reporting of exposures to employers. METHODS: A questionnaire was mailed in 2002-2003 to a national sample of paramedics selected using a two-stage design. Information on exposure reporting was obtained on the two most recent exposures for each of five routes of exposure. RESULTS: Forty-nine percent of all exposures to blood and 72% of needlesticks were reported to employers. The main reason for under-reporting was not considering the exposure a "significant risk." Females reported significantly more total exposures than males. Reporting of needlesticks was significantly less common among respondents who believed most needlesticks were due to circumstances under the worker's control. Reporting was non-significantly more common among workers who believed reporting exposures helps management prevent future exposures. Reporting may have been positively associated with workplace safety culture. CONCLUSIONS: This survey indicates there is need to improve the reporting of blood exposures by paramedics to their employers, and more work is needed to understand the reasons for under-reporting. Gender, safety culture, perception of risk, and other personal attitudes may all affect reporting behavior.
