Use of safety devices and the prevention of percutaneous injuries among healthcare workers.

OBJECTIVE: To study the effectiveness of safety devices intended to prevent percutaneous injuries.Design. Quasi-experimental trial with before-and-after intervention evaluation. SETTING: A 350-bed general hospital that has had an ongoing educational program for the prevention of percutaneous injuries since January 2002. METHODS: In October 2005, we implemented a program for the use of engineered devices to prevent percutaneous injury in the emergency department and half of the hospital wards during the following procedures: intravascular catheterization, vacuum phlebotomy, blood-gas sampling, finger-stick blood sampling, and intramuscular and subcutaneous injections. The nurses in the wards that participated in the intervention received a 3-hour course on occupationally acquired bloodborne infections, and they had a 2-hour "hands-on" training session with the devices. We studied the percutaneous injury rate and the direct cost during the preintervention period (October 2004 through March 2005) and the intervention period (October 2005 through March 2006). RESULTS: We observed a 93% reduction in the relative risk of percutaneous injuries in areas where safety devices were used (14 vs 1 percutaneous injury). Specifically, rates decreased from 18.3 injuries (95% confidence interval [CI], 5.9-43.2 injuries) to 0 injuries per 100,000 patients in the emergency department (P=.002) and from 44.0 injuries (95% CI, 20.1-83.6 injuries) to 5.2 injuries (95% CI, 0.1-28.8 injuries) per 100,000 patient-days in hospital wards (P=.007). In the control wards of the hospital (ie, those where the intervention was not implemented), rates remained stable. The direct cost increase was 0.558 euros (US$0.753) per patient in the emergency department and 0.636 euros (US$0.858) per patient-day in the hospital wards. CONCLUSION: Proper use of engineered devices to prevent percutaneous injury is a highly effective measure to prevent these injuries among healthcare workers. However, education and training are the keys to achieving the greatest preventative effect.     

Impact of a shielded safety syringe on needlestick injuries among healthcare workers.

OBJECTIVES: Evaluate the impact of a shielded 3 cc safety syringe on needlestick injuries among healthcare workers. DESIGN: Surveillance study. SETTING: Three medical centers. RESULTS: The total number of needlesticks from all sources rose from 134 during the baseline period to 140 during the study phase. However, the overall rate of needlesticks involving 3 cc syringes decreased from 14/100,000 inventory units to 2/100,000, and the frequency declined substantially at each of the participating medical centers. CONCLUSIONS: These results suggest that shielded syringes and related technology may offer potential for reducing the risk of needlestick injuries among hospital and other healthcare employees. This study should be viewed as a preliminary effort to assess the potential of shielded-syringe technology for reducing the risk of needlestick injuries among healthcare workers. The results are encouraging, but more clinical experience with this new device and longer follow up are essential to provide the data necessary for a definitive assessment of efficacy.

Preventability of percutaneous injuries in healthcare workers: a year-long survey in Italy

The aim of the study was to examine the preventability of percutaneous injuries either through the adoption of correct behaviour or by the use of needles with safety features. We analysed the report forms of occupational needlestick or sharps injuries in a sample of healthcare workers exposed to the risk of percutaneous injuries in the period between 1 June 2000 and 31 May 2001; the forms were returned to the regional SIROH (Italian Study on Occupational Exposure to HIV) centre in which all hospitals of the Piemonte region (Italy) participate. Percutaneous injuries caused by needles (injection, phlebotomy, infusion), suture needles and scalpels were analysed; three samples were extracted according to the type of device that caused the injury. In the sample of 439 needlestick-related percutaneous injuries, 74% were caused by incorrect health worker behaviour and 26% were unpreventable, seventy-nine percent of accidents caused by incorrect behaviour and 24% of accidents could have been prevented by using needles with safety features. In the sample of 221 suture needle and 114 scalpel injuries, incorrect health worker behaviour was identified in 26.2% and 14%, respectively, and unpreventable causes in 73.8% and 50.9%, respectively. A high rate of percutaneous injuries, especially those involving needles for injection, phlebotomy, infusion, and scalpels, could be prevented by adopting safe work behaviour practices and using personal protection equipment. The introduction of devices with safety features could lead to a significant reduction in the number of injuries from needles.     

Health behavior associated with influenza vaccination among healthcare workers in long-term-care facilities.

OBJECTIVE: To investigate the health behavior associated with influenza vaccination among healthcare workers (HCWs) in long-term-care facilities. DESIGN: A cross-sectional, self-administered survey of HCWs, augmented with focus groups to further examine attitudes toward influenza vaccination. SETTING: Two long-term-care facilities participated in the survey. The focus groups were held at one of the two facilities. PARTICIPANTS: All HCWs were invited to participate in the survey and all nonmanagerial staff members were invited to participate in the focus groups. The response rate for the survey was 58% (231 of 401). RESULTS: Vaccinated HCWs had a more positive attitude toward influenza vaccination and a greater belief that the vaccine is effective. This was not accompanied by differences in vaccine knowledge or values of potential preventive outcomes. Nonvaccinated respondents were more likely to believe that other preventive measures, such as washing hands, taking vitamins and supplements, eating a nutritious diet, exercising, and taking homeopathic or naturopathic medications, were more effective than vaccination. Additional findings from the focus groups suggest that HCWs believe that the main purpose of influenza vaccination programs is to protect residents' health at the expense, potential harm, and burden of responsibility of the staff. CONCLUSIONS: This study identifies challenges to and opportunities for improving vaccination rates among HCWs. A message that emphasizes the health benefits of vaccination to staff members, such as including vaccination as part of a staff "wellness" program, may improve the credibility of influenza immunization programs and coverage rates.     

Estimate of the annual number of percutaneous injuries among hospital-based healthcare workers in the United States, 1997-1998.

OBJECTIVE: To construct a single estimate of the number of percutaneous injuries sustained annually by healthcare workers (HCWs) in the United States. DESIGN: Statistical analysis. METHODS: We combined data collected in 1997 and 1998 at 15 National Surveillance System for Health Care Workers (NaSH) hospitals and 45 Exposure Prevention Information Network (EPINet) hospitals. The combined data, taken as a sample of all U.S. hospitals, were adjusted for underreporting. The estimate of the number of percutaneous injuries nationwide was obtained by weighting the number of percutaneous injuries at each hospital by the number of admissions in all U.S. hospitals relative to the number of admissions at that hospital. RESULTS: The estimated number of percutaneous injuries sustained annually by hospital-based HCWs was 384,325 (95% confidence interval, 311,091 to 463,922). The number of percutaneous injuries sustained by HCWs outside of the hospital setting was not estimated. CONCLUSIONS: Although our estimate is smaller than some previously published estimates of percutaneous injuries among HCWs, its magnitude remains a concern and emphasizes the urgent need to implement prevention strategies. In addition, improved surveillance could be used to monitor injury trends in all healthcare settings and evaluate the impact of prevention interventions.

A nested case-control study of fatal work related injuries among Brazilian steel workers.

OBJECTIVES: To estimate the relative risk of death from work related injury in a steelworks, associated with exposure to various occupational hazards, sociodemographic factors, and medical history. MATERIAL AND METHODS: The study was a nested case-control design. It was based on a cohort of men employed in the steel plant of USIMINAS, Brazil between January 1977 and August 1990, who were followed up to November 1992. The cases were defined as all workers in the cohort who died from injury in the study period and whose death had been notified to the Brazilian Ministry of Labour as being related to work. Four controls per case, matched to cases on year of birth, were randomly selected from among workers employed in the plant at the time of death of the matching case. Data on potential risk factors for occupational injury were extracted from company records; for the controls these data were abstracted for the period preceding the death of the matching case. RESULTS: There were 37 deaths related to work injuries during the study period. Four surviving workers were selected as controls for each case, but for eight the personnel records were incomplete, leaving 140 controls in all. Significantly increased risk of fatal injury related to work was associated with exposure to noise, heat, dust and fumes, gases and vapours, rotating shift work, being a manual worker, and working in the steel mill, coke ovens, blast furnaces, and energy and water supply areas. Risk of fatal injury related to work increased with intensity of exposure to noise (P (trend) = 0.004) and heat (P < 0.001), and increased greatly with a hazard score that combined information on noise, heat, dust, and gas exposure (P < 0.001). Number of years of schooling (P = 0.03) and salary level (P = 0.03) were both negatively associated with risk. In a multivariate analysis including all these significant factors, only hazard score and area of work remained associated with death from injury related to work. The highest risks were for men exposed to all four environmental hazards (odds ratio (OR) 19.4; 95% confidence interval (95% CI) 1.1 to 352.1) and those working in the energy supply area (OR 18.0; 1.6 to 198.1). CONCLUSIONS: The study identified parts of the steelworks and types of hazard associated with greatly increased risk of fatal accident. Research and measures to prevent accidents need to concentrate on these areas and the people working in them. The use of a hazard score was successful in identifying high risk, and similar scoring might prove useful in other industrial situations.

Potential for reported needlestick injury prevention among healthcare workers through safety device usage and improvement of guideline adherence: expert panel assessment

A prospective survey was conducted over six months in order to estimate the proportion of reported occupational needlestick injuries sustained by National Health Service (NHS) Scotland staff that could have been prevented through either safety device introduction, improved guideline adherence, guideline revision or a combination of these. This survey involved the administration of a standard proforma to healthcare workers followed by an expert panel assessment. All acute and primary care NHS Scotland trusts, the Scottish Ambulance Service and the Scottish National Blood Transfusion Service were included. Proforma and expert panel assessment data were available for 64% of injuries (952/1497) reported by healthcare staff. These injuries were all percutaneous. The expert panel concluded that: 56% of all injuries and 80% of venepuncture/injection administration injuries would probably/definitely have been prevented through safety device usage, 52% of all injuries and 56% of venepuncture/injection administration injuries would probably/definitely have been prevented through guideline adherence and 72% of all injuries and 88% of venepuncture/injection administration injuries would probably/definitely have been prevented through either intervention. Multi-factorial analysis indicated that injuries sustained through venepuncture/injection administration were significantly more likely to be prevented through safety device usage [adjusted odds ratio (OR) 5.09, 95% confidence intervals (CI) 3.11-8.31 and adjusted OR 2.70, 95% CI 1.64-4.45, respectively], and significantly less likely to be prevented through guideline adherence (adjusted OR 0.26, 95% CI 0.11-0.60 and adjusted OR 0.31, 95% CI 0.12-0.78, respectively). Injuries sustained after completing procedures were significantly more likely to be prevented through safety device usage and guideline adherence. The study's findings support the need for improvements to staff's adherence to needlestick injury guidelines and appropriate implementation of safety devices for venepuncture and injection administration.     

Pathogenic organisms associated with artificial fingernails worn by healthcare workers.

OBJECTIVE: To determine differences in the identity and quantity of microbial flora from healthcare workers (HCWs) wearing artificial nails compared with control HCWs with native nails. DESIGN: Two separate studies were undertaken. In study 1, 12 HCWs who did not normally wear artificial nails wore polished artificial nails on their nondominant hand for 15 days. Identity and quantity of microflora were compared between the artificial nails and the polished native nails of the other hand. In study 2, the microbial flora of the nails of 30 HCWs who wore permanent acrylic artificial nails were compared with that of control HCWs who had native nails. In both studies, nail surfaces were swabbed and subungual debris was collected to obtain material for culture. Staphylococcus aureus, gram-negative bacilli, enterococci, and yeasts were considered to be potential pathogens. All organisms were identified and quantified. RESULTS: In study 1, potential pathogens were isolated from more samples obtained from artificial nails than native nails (92% vs. 62%; P<.001). Colonization of artificial nails increased over time; by day 15, 71% of cultures yielded a pathogen compared with 21% on day 1 (P=.004). A significantly greater quantity of organisms (expressed as mean log10 colony-forming units +/- standard deviation) was isolated from the subungual area than the nail surface; this was noted for both artificial (5.0+/-1.4 vs. 4.1+/-1.0; P<.001) and native nails (4.9+/-1.3 vs. 3.7+/-0.8; P<.001). More organisms were found on the surface of artificial nails than native nails (P=.008), but there were no differences noted in the quantities of organisms isolated from the subungual areas. In study 2, HCWs wearing artificial nails were more likely to have a pathogen isolated than controls (87% vs. 43%; P=.001). More HCWs with artificial nails had gram-negative bacilli (47% vs. 17%; P=.03) and yeasts (50% vs. 13%; P=.006) than control HCWs. However, the quantities of organisms isolated from HCWs wearing artificial nails and controls did not differ. CONCLUSIONS: Artificial fingernails were more likely to harbor pathogens, especially gram-negative bacilli and yeasts, than native nails. The longer artificial nails were worn, the more likely that a pathogen was isolated. Current recommendations restricting artificial fingernails in certain healthcare settings appear justified.     

Influenza vaccination among healthcare workers in a university children's hospital.

OBJECTIVES: To evaluate the attitudes of pediatric healthcare workers (HCWs) toward influenza vaccination and to increase their rate of immunization. METHODS: A survey was conducted among pediatric HCWs using an anonymous questionnaire. Survey results were used to design an intervention to increase the immunization rate of staff. Immunization rates before (2003-2004) and after (2004-2005) intervention were assessed using immunization clinic records. SETTING: A university children's hospital in Switzerland. INTERVENTIONS: (1) An informational letter based on misconceptions noted in the survey, (2) educational conversations with head nurses, (3) more "walk-in" immunization clinics, and (4) a direct offer of influenza immunization on the wards. RESULTS: Among vaccine nonrecipients, doubts about the efficacy and necessity of influenza immunization were prevalent and more often reported by nurses than physicians (75% vs 41%, P = .002; and 55% vs 23%, P = .001, respectively). Physicians more often than nurses reported lack of time as a reason for not receiving influenza vaccination (23% vs 5%, P = .01). After intervention, the immunization rate of HCWs increased from 19% to 24% (P = .03). The immunization rate of physicians increased from 43% to 64% (P = .004). No change was noted among nurses (13% vs 14%) and other HCWs (16% vs 16%). CONCLUSIONS: Misconceptions about influenza vaccination were prevalent among pediatric staff, particularly nurses. Active promotion and educational efforts were successful in increasing the immunization rate of physicians but not nurses and other HCWs.     

Epidemiology of biological-exposure incidents among Spanish healthcare workers.

OBJECTIVE: To determine the frequency and the epidemiological characteristics of biological-exposure incidents occurring among healthcare personnel. DESIGN: Prospective surveillance study. SETTING: Participating Spanish primary-care and specialty centers from January 1994 to December 1997. PARTICIPANTS: 70 centers in 1994, 87 in 1995, 97 in 1996, and 104 in 1997. METHODS: Absolute and relative frequencies were calculated for several variables (position held, area of care, type of injuring object, activity, etc) and for the different categories of each variable. RESULTS: There were 20,235 registered incidents. Annual incidence rates were as follows: 1994, 51 per 1,000; 1995, 58 per 1,000, 1996, 54 per 1,000; and 1997, 59 per 1,000. Mean age of accident victims was as follows: 1994, 35.68 (standard deviation [SD], 16.26); 1995, 33.6 (SD, 11.9); 1996,38.2 (SD, 17.27); and 1997, 36.7 (SD, 16.33) years. Of the 20,235 incidents, 15,860 (80.7%) occurred to women; 50% (9,833) accidents were among nursing staff. The type of incident most frequently reported was percutaneous injury (81.1%). The highest frequency of accidents was seen in medical and surgical areas (28% and 25.6%, respectively). Blood and blood products were the most commonly involved material (87.6%). Administration of intramuscular or intravenous medication was the activity associated with the highest accident rate (20.3%). The most frequent immediate action in response was rinsing and disinfecting (65.6%). CONCLUSIONS: The incident registry was highly stable in terms of incidence rates over the observation period and served to highlight the large number of incidents recorded each year. The potential implications of the results are the need to explore reasons for increased exposures in certain areas, with the aim of focusing prevention efforts, and, similarly, to establish the factors associated with diminished incidence rates to model successful measures.     

Outbreak of pertussis among healthcare workers in a hospital surgical unit.

BACKGROUND: In September 1999, a pertussis outbreak was detected among surgical staff of a 138-bed community hospital. Patients were exposed to Bordetella pertussis during the 3-month outbreak period. OBJECTIVE: To describe the outbreak among surgical staff, to evaluate implemented control measures, and to determine whether nosocomial transmission occurred. METHODS: Clinical pertussis was defined as acute cough illness with a duration of 14 days or more without another apparent cause; persons with positive culture, PCR, or serologic test results were defined as having laboratory-confirmed pertussis. Surgical healthcare workers (HCWs) were interviewed regarding pertussis symptoms, and specimens were obtained for laboratory analysis. Patients exposed to B. pertussis during an ill staff member's 3-week infectious period were interviewed by phone to determine the extent of nosocomial spread. PARTICIPANTS: A total of 53 HCWs assigned to the surgical unit and 146 exposed patients. HCWs with pertussis were defined as case subjects; HCWs without pertussis were defined as non-case subjects. RESULTS: Twelve (23%) of 53 HCWs had clinical pertussis; 6 cases were laboratory confirmed. The median cough duration in the 12 case subjects was 27 days (range, 20-120 days); 10 (83%) had paroxysms. Eleven (92%) of 12 case subjects and 28 (86%) of 41 non-case subjects received antibiotic treatment or prophylaxis. Seven case subjects (58%) reported they always wore a mask when near patients. Of 146 patients potentially exposed to pertussis from the 12 case subjects, 120 (82%) were interviewed; none reported a pertussis-like illness. CONCLUSIONS: Surgical staff transmitted B. pertussis among themselves; self-reported data suggests that these HCWs did not transmit B. pertussis to their patients, likely because of mask use, cough etiquette, and limited face-to-face contact. Control measures might have helped limit the outbreak once pertussis was recognized.     

Prevalence and prevention of needlestick injuries among health care workers in a German university hospital

Objective Health care workers (HCWs) are exposed to bloodborne pathogens, especially hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency virus (HIV) through job-related risk factors like needlestick, stab, scratch, cut, or other bloody injuries. Needlestick injuries can be prevented by safer devices. Methods The purpose of this study was to investigate the frequency and causes of needlestick injuries in a German university hospital. Data were obtained by an anonymous, self-reporting questionnaire. We calculated the share of reported needlestick injuries, which could have been prevented by using safety devices. Results 31.4% (n = 226) of participant HCWs had sustained at least one needlestick injury in the last 12 months. A wide variation in the number of reported needlestick injuries was evident across disciplines, ranging from 46.9% (n = 91/194) among medical staff in surgery and 18.7% (n = 53/283) among HCWs in pediatrics. Of all occupational groups, physicians have the highest risk to experience needlestick injuries (55.1%—n = 129/234). Evaluating the kind of activity under which the needlestick injury occurred, on average 34% (n = 191/561) of all needlestick injuries could have been avoided by the use of safety devices. Taking all medical disciplines and procedures into consideration, safety devices are available for 35.1% (n = 197/561) of needlestick injuries sustained. However, there was a significant difference across various medical disciplines in the share of needlestick injuries which might have been avoidable: Pediatrics (83.7%), gynecology (83.7%), anesthesia (59.3%), dermatology (33.3%), and surgery (11.9%). In our study, only 13.2% (n = 74/561) of needlestick injuries could have been prevented by organizational measures. Conclusion There is a high rate of needlestick injuries in the daily routine of a hospital. The rate of such injuries depends on the medical discipline. Implementation of safety devices will lead to an improvement in medical staff’s health and safety.
