Needle-stick injuries in the National Health Service: a culture of silence

Injury by contaminated sharp instruments and needles constitutes a major occupational hazard for healthcare workers. In a confidential survey at a district general hospital, 300 healthcare professionals were asked about their personal experience of needle-stick injury and their attitudes to reporting. 279 individuals responded, of whom 38% had experienced at least one needle-stick (mean 1.8) in the past year and 74% had sustained such an injury during their careers (mean 3.0). Although 80% of respondents were aware that such incidents should be notified, only 51% of those affected had reported all needle-stick injuries. Doctors were less likely to report than nurses, despite a higher liability to injury. This survey adds to evidence of a culture of silence pertaining to needle-stick injuries. The consequent risks to health, and the ethical and financial implications, remain uncertain.

某院医务人员锐器伤目标性监测

目的了解某院医务人员发生锐器伤的人群分布特征和风险环节,为制定有效防护措施提供依据。方法回顾性调查2014年1-12月该三级甲等医院医务人员上报医院感染管理科的职业暴露情况,分析发生锐器伤者的职业类别、暴露地点及环节、暴露源等情况。结果2014年1-12月共监测医务人员2 643名,发生锐器伤61名,其中护士43名（占70.49%）,医生13名（占21.31%）。医务人员锐器伤职业暴露科室主要为骨科（9名,占14.75%）,致伤锐器主要为输液针（33名,占54.10%）,发生的主要操作环节为拔针（21名,占34.43%）;暴露源主要为乙型肝炎病毒（HBV）,共36例（占59.01%）;34名（占55.74%）锐器伤职业暴露医务人员在操作中均未戴手套。锐器伤职业暴露后进行局部处理者54名（占88.52%）,进行药物治疗（含预防用药）者仅18名（占29.51%）;追踪随访43名（占70.49%）,均未因暴露而发生感染。结论医院应建立完善的锐器伤职业暴露监控体系,加强对发生锐器伤高危人群的培训,强化标准预防,对风险环节进行监控和干预,有效减少医务人员锐器伤的发生。     

Detection of HGV in serum and peripheral blood mononuclear cells of maintenance haemodialysis patients.

The aim of the present study was to investigate the prevalence of hepatitis G virus (HGV) and also hepatitis C virus (HCV) infections in maintenance haemodialysis patients, and to identify extrahepatic sites as HGV reservoirs. HGV RNA was detected in the serum of 6/61 (10%) patients and in the peripheral blood mononuclear cells of 2/61 (3%) patients (one of whom was serum negative). These findings suggest that lymphoid cells constitute an extrahepatic HGV reservoir. HCV RNA was detected in 7/61 (11%) patients. Five of these patients (71%) were identified as carrying HCV genotype 1b. Co-infection with HCV and HGV was detected only in one patient. Haemodialysis patients are at risk for HGV infection, by nosocomial routes or via transfusions. HGV itself does not seem to be an important cause of hepatitis since all six HGV RNA positive patients not co-infected by HCV or HBV showed normal ALT values.     

The prevalence of TT virus and GB virus C/hepatitis G virus infection in individuals with raised liver enzymes but without HBV or HCV infection in Taiwan

The prevalence of TT virus (TTV) and GB virus-C/hepatitis G virus (GBV-C/HGV) infection and the association with raised liver function tests in 546 Taiwanese with negative HBsAg, anti-HCV and HCV RNA was elucidated. They were tested for serum alanine aminotransferase (ALT), GBV-C/HGV RNA, anti-envelope protein 2 antibody (anti-E2) and TTV DNA. Direct sequencing and phylogenetic analyses were performed on 58 isolates for TTV genotype determination. The prevalence of TTV DNA, GBV-C/HGV RNA, anti-E2 and over all GBV-C/HGV exposure was 24.9, 3.4, 8.2 and 11.1%, respectively. Using uni- and multi-variate analyses, male gender and TTV viremia were associated significantly with raised ALT values. Sixty-nine percent of TTV isolates were deduced to be TTV genotype 1 and they had significantly lower mean age than genotype non-1 isolates. In the population, raised ALT may be related to male gender and be attributable to TTV infection but not to GBV-C/HGV among individuals with no evidence of current HBV and HCV infection. TTV genotype 1 is the most prevalent genotype and associated with younger age.     

Prevalence of hepatitis C antibodies in a large sample of Belgian healthcare workers.

OBJECTIVE: To assess the risk of hepatitis C virus (HCV) infection among Belgian (Flemish) healthcare workers. DESIGN: A seroprevalence survey of HCV IgG antibodies. SETTING AND PARTICIPANTS: A systematic sample of 5,064 employees from 22 general hospitals in Flanders and Brussels, Belgium, was tested at the annual occupational medical examination. Together with demographic and occupational data, information was collected on the frequency of blood contact, needlestick injuries, and medical and surgical history. The blood samples were tested using the third-generation Abbott Screen Kit test, with confirmation by Matrix, LIA, and an in-house polymerase chain reaction and the Quantiplex-HCV b-DNA test. RESULTS: 21 persons were found to be positive for HCV markers. The overall prevalence was 0.41% (95% confidence interval [CI95], 0.24-0.59). A statistically significant association was found with a history of blood transfusion (odds ratio [OR], 4.14; CI95, 1.67-10.31) and with history of a clinically apparent hepatitis (OR, 3.98; CI95, 1.60-9.90). Although the ORs for the frequency of blood contact were slightly elevated (between 1.17 and 2.73), this association was not significant. Moreover, a history of needlestick injuries showed a nonsignificant OR of 1.28 (CI95, 0.53-3.09), and no statistically significant difference was found with a variety of duties and tasks. The ORs for potential occupational risk factors were adjusted according to age, gender, antecedents, and other confounders using a logistic regression analysis. Based on this procedure, the ORs decreased slightly. CONCLUSIONS: Flemish healthcare workers showed a lower HCV seropositivity than is seen in the general population; a history of blood transfusion and of clinically apparent hepatitis was most strongly associated with the presence of HCV markers. We concluded that employees in Flemish regional general hospitals are not at an overall increased risk for HCV infection, although occasional transmission through percutaneous injuries is possible, and prevention therefore remains imperative.     

The use of a quality-improvement approach to reduce needlestick injuries in a Saudi Arabian hospital

OBJECTIVE/DESIGN: An increase was noted in the incidence of needlestick injuries in our institution. A retrospective study was carried out analyzing the accident reports and medical records of needle-stick injuries from January 1995 to July 1996. Study variables included monthly incidence; location; injury site; mechanism; staff vocational status; source virological status; staff immunity; and serological conversion to hepatitis B and C viruses and the human immunodeficiency virus (HIV). SETTING: 350-bed general hospital in Western Saudi Arabia employing 2,083 employees of many different nationalities. RESULTS: 126 injuries were identified. Thirty percent of injuries occurred in the operating room and 28% on general wards. Twenty-five injuries occurred during a surgical procedure in the operating room, 22 injuries were caused by undisposed sharps, 11 occurred during suturing, 11 occurred during injection, and 10 occurred while disposing of refuse. At least 38% of the injuries were avoidable. Sixty percent of those injured were nurses, 30% were medical staff, and 6% were housekeeping staff. Nine of the identifiable sources were hepatitis B surface antigen-positive, nine were hepatitis C antibody-positive, and none were anti-HIV positive. Eighty-nine percent of injuries involved the hands. None of our injured employees had seroconverted at 3, 6, or 9 months follow-up to HIV, hepatitis C, or hepatitis B. Eighty-four percent of injured staff were hepatitis B immune. CONCLUSION: Steps taken to reduce the future incidence of injuries included the provision of readily accessible sharps boxes, a hospitalwide education program focusing on safe handling and disposal of sharps, and the development of clear policies and procedures for dealing with sharps injuries. A further study will be conducted 12 months after the introduction of these measures.

Prevention of needle-stick injury by the scooping-resheathing method

Background The objective of this study was to determine the effects of teaching the scooping resheathing method on the incidence of needle-stick injuries in medical students. Methods Before starting their first clerkship, 81 medical students were given a 15-min lecture on the high incidence and dangers of needle-stick injuries and a demonstration of the scooping-resheathing method. The number of needle-stick injuries that occurred during the 3-month clerkship was compared with the number reported by 86 medical students who had completed their first clerkship 1 year previously and had not been given such instruction. Results Compared with controls, the study group had a 3.8-fold lower risk of needle-stick injury (95% confidence interval, 2.0–7.4, P < 0.0001) and a 8.3-fold lower risk of multiple needle-stick injuries (95% confidence interval, 2.0–35.0, P < 0.001). Those in the study group, who consistently used the scooping method had a much lower risk of injury than those who did not (1 of 36 [2.8%] vs. 8 of 45 [17.4%], P = 0.039). Conclusions We conclude that a lecture recommending the scooping-resheathing method is effective in reducing the risk of needle-stick injuries in medical students during their first rotation. Because this is the first time that an intervention not requiring change in equipment has been successful, further studies are warranted to substantiate our findings and for extrapolation to other medical personnel in other cultural settings.

Injuries due to assaults on psychiatric hospital employees in Washington state

In order to estimate rates and identify risk factors for assaults on employees of a state psychiatric hospital, we examined workers' compensation claims, hospital-recorded incident reports, and data collected in a survey of ward staff. Results revealed 13.8 workers' compensation claims due to assault per 100 employees per year. Assaults were responsible for 60% of total claims. Incident reports revealed 35 injuries due to assault per 100 employees per year. Survey data revealed 415 injuries due to assault per 100 employees per year. Of the respondents, 73% reported at least a minor injury during the past year. Assault management training in the past year was associated with less severe injuries. Working in isolation, the occupation of mental health technician, and working on the geriatric-medical hospital unit were associated with more severe injuries during the past year. Assaults on staff in psychiatric hospitals represent a significant and underrecognized occupational hazard. Am. J. Ind. Med. 31:92–99 © 1997 Wiley-Liss, Inc.     

维持性血液透析患者庚型肝炎病毒感染的研究

目的 了解血液透析患者庚型肝炎病毒(HGV)感染情况，探讨其危险因素。方法 采用酶联免疫法(ELISA)和逆转录—套式PCR法分别检测44例血透患者的抗—HGV抗体和HGVRNA。结果 血透患者HGV感染率为13．6％，HGV阳性组与阴性组相比输血次数较多、透析时间较长，但差异无显著性；而单独HGV阳性组与全阴性组相比透析时间明显延长，HGV感染与年龄、HBV感染、HCV感染及肝功能损害无显著相关。结论 血透患者HGV感染率明显高于普通人群，严格消毒措施、预防交叉感染、减少输血、血源中HGV筛查，对减少透析中庚型肝炎病毒感染至关重要。     

Risk of hepatitis A infection in sewage workers

OBJECTIVE: To evaluate the risk of hepatitis A virus (HAV) infection among sewage workers from occupational exposure to raw sewage. METHODS: An analytical cross sectional study of 241 company employees with possible occupational exposure to sewage in a large water and sewerage company was carried out. Previous exposure to hepatitis A virus infection was assessed, as were its associations with possible risk factors. RESULTS: Frequent occupational exposure to raw sewage was a significant risk factor for HAV infection, independently of other known risk factors (odds ratio 3.73, 95% confidence interval 1.48 to 9.37). Of 50 employees who reported occupational exposure to raw sewage most of the time, 30 (60%) had had HAV infection. CONCLUSION: Employees who are likely to be at risk of frequent exposure should have their immunity ensured. The salivary assay for IgG anti-HAV used in the study was highly specific and would be suitable for prevaccination testing of older employees, who are more likely to be immune.

 

     

Hepatitis c virus infection in employees of a large university hospital in Israel.

OBJECTIVE: To assess whether hospital work constitutes a risk factor for hepatitis C virus (HCV) infection among employees of a large hospital in Israel. DESIGN: Seroprevalence survey. SETTING: A 1,006-bed, tertiary-care university hospital in Jerusalem. PARTICIPANTS: All 5,444 employees (18-65 years old) were eligible; 4,287 (79%) participated in the survey. METHODS: Sera were tested for antibodies to HCV (anti-HCV) using a third-generation enzyme immunoassay. A third-generation strip immunoblot assay was used for confirmation. Participants were interviewed regarding their occupational history, and they completed a self-administered questionnaire covering history of non-occupational exposure to blood and country of birth. Other demographic information was obtained from the personnel department. Rates and odds ratios (ORs) were calculated, and multivariate logistic-regression analyses were performed to adjust for potential confounding variables. RESULTS: Anti-HCV was found in 0.9% of employees (37/4,287; 95% confidence interval, 0.6-1.1), ranging from 0.1% among those born in Israel to 5.7% among those born in Central Asia. After age, gender, social status, country of birth, and history of blood transfusion were controlled for in a logistic regression, occupational exposure to blood > or = 10 years was significantly associated with the presence of antibodies (OR, 2.6; P=.01). Presence of anti-HCV also was associated with country of birth (range: Israel OR, 1; West OR, 3.8 [P=.1]; Central Asia OR, 48.6 [P<.0001]) and history of blood transfusion (OR, 2.7; P=.01). No significant associations were found between anti-HCV and age, gender, social status, history of tattoo, acupuncture, current occupation, department, exposure to blood in current occupation, adherence to safety precautions, or history of percutaneous injury. The association with length of exposure was stronger (OR, 3.6; P=.01) when the same logistic regression was run excluding the outlier ethnic group of Central Asia. CONCLUSIONS: Hospital work does not seem to constitute a major risk factor for HCV infection in Israel today. A higher prevalence of anti-HCV among employees with longer versus shorter lengths of occupational exposure may be due to a cumulative effect of exposure over the years. Infection control efforts in recent years may have contributed to this association.     

The impact of shift work on the risk and severity of injuries for hospital employees: an analysis using Oregon workers' compensation data

BACKGROUND: While past research on health care workers has found that shift work can lead to negative physiological and psychological consequences, few studies have assessed the extent to which it increases the risk of specific work-related injuries, nor quantified and compared associated types, severity and costs. AIMS: This study aimed to derive and compare the rates, typologies, costs and disability time of injuries for various hospital worker occupations by day, evening and night shift. METHODS: This study used Oregon workers' compensation claim data from 1990 to 1997 to examine the differences in hospital employee claims (n = 7717) by shift and occupation. Oregon hospital employee claim data, hospital employment data from Oregon's Labor Market Information System and shift proportion estimates derived from the Current Population Survey (CPS) were used to calculate injury rate estimates. RESULTS: The injury rate for day shift per 10,000 employees was estimated to be 176 (95% CI 172-180), as compared with injury rate estimates of 324 (95% CI 311-337) for evening shift and 279 (95% CI 257-302), night shift workers. The average number of days taken off for injury disability was longer for injured night shift workers (46) than for day (38) or evening (39) shift workers. CONCLUSION: Evening and night shift hospital employees were found to be at greater risk of sustaining an occupational injury than day shift workers, with those on the night shift reporting injuries of the greatest severity as measured by disability leave. Staffing levels and task differences between shifts may also affect injury risk.     

医务人员血源性病原体职业暴露危险因素分析及对策

The joint effect of noise exposure and job complexity on distress and injury risk among men and women: the cardiovascular occupational risk factors determination in Israel study

We sought to explore the possibility that exposure to noise at work might interact with job complexity and gender to affect the incidence of occupational injury among industrial employees. In this study, we examined 4084 men and 1643 women from 21 industrial plants while controlling for a number of potent confounding variables, among them active safety hazards. Logistic regression results showed that the predictor variables interacted and that the highest injury risk (odds ratio = 2.72) was observed in women in high noise and high job complexity, compared with the referents scoring low on these predictors. The comparable injury risk in men was only 1.3. Parallel results were observed for three noise stress indicators: workload, noise annoyance and postwork irritability. We conclude that the joint exposure to noise and high job complexity is disruptive, resulting in higher distress and occupational injury risk, particularly among women.
