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.     

Needlestick injuries among nurses of Fars province, Iran

PURPOSE: A prevalence survey was performed to estimate the magnitude and predictors for needlestick injury (NSI) in nurses of Fars province hospitals. METHODS: Questionnaires were distributed in 52 hospitals to a stratified random sample of 2,118 (46.3%) nurses between April and September 2005 to collect self-reported NSI in the past 12- months. RESULTS: Of the 1,555 nurses who returned a completed questionnaire, 49.6% (95% confidence interval [95 CI] 47.1%-52.1%) recalled at least one sharps injury, of which 52.6% were classified as NSI. Just over one fourth (26.3%; 95 CI 24.1%-28.6%, 409/1,555) of respondents sustained at least one NSI, 75.6% (95 CI 71.1%-79.6%) recalled having sustained between 1 and 4 injuries in the past 12-months, of which 72.2% involved a hollow-bore needle and 95.1% of injuries involved fingers. Predictors of NSI included being a registered nurse (odds ratio [OR] 1.6, 95% CI 1.1-2.3) or midwife (OR 2.4, 95% CI 1.4-3.9) compared with nurse managers, being employed in a hospital located in other cities smaller than Shiraz (OR 1.4, 95% CI 1.1-1.8). Nurses who reported a previous contaminated NSI were less likely to sustain a further injury (OR 0.3, 95% CI 0.2-0.4). CONCLUSION: The prevalence of NSI in Iranian nurses is high, with the majority of injured staff having sustained up to 4 NSIs in a 12-month period. Nearly all NSIs were high-risk injuries involving a hollow-bore needle. Providing nursing staff with safety-engineered devices, including retractable syringes when hollow-bore needles are to be used, will be an important step toward reducing our NSI epidemic.     

Evaluation of potential reduction in blood and body fluid exposures by use of alternative instruments

BACKGROUND: Injuries from needlestick, sharps injuries and splashes lead to exposure to blood and body fluids with the potential for transmission of blood-borne viruses. AIMS: To identify alternative instruments, which if used would improve worker safety. METHODS: Retrospective review of 161 injuries with identification of safer alternative products for instruments that caused injury. The proportion of injuries that could be prevented was calculated [with 95% confidence intervals (CI)]. RESULTS: The average rate of injury was 7.8/1000 employees per annum (95% CI, 6.8-9.4/1000). In the 2 years the highest rates of injury occurred in pre-registration house officers (164/1000; 95% CI, 64-264/1000), phlebotomists (154/1000; 95% CI, 15-291/1000) and senior house officers (45/1000; 95% CI, 13-77/1000). An upper estimate of 65% (95% CI, 58-72%) of incidents would have been preventable with a change to alternative devices. CONCLUSIONS: Change to the use of intrinsically safer instrumentation has the potential to prevent injury to healthcare workers.     

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.     

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.     

Adverse work and environmental conditions predict occupational injuries. The Israeli Cardiovascular Occupational Risk Factors Determination in Israel (CORDIS) Study.

This study was designed to test whether the total objective adverse work and environmental conditions, expressed as the ergonomic stress level (ESL), would predict occupational injuries over a 2-year period. The study population consisted of 4,096 men from 21 factories in six industrial sectors who were studied as part of the Israeli Cardiovascular Occupational Risk Factors Determination in Israel (CORDIS) Study, 1985-1987. The ESL (assigned four levels, 1-4) was based on an ergonomic assessment which covered 17 risk factors pertaining to safety hazards, overcrowding, cognitive and physical demands, and environmental stressors. The ESL was found to be a highly reliable measure and stable over a period of 2-4 years. The incidence of injuries among workers in low ESL conditions (level 1) was 10.3%. It increased with higher ESL's: 11.7% in level 2 (relative risk (RR) = 1.13, 95% confidence interval (CI) 0.86-1.50); 21.6% in level 3 (RR = 2.09, 95% CI 1.68-2.62); and 23.8% in level 4 (RR = 2.31, 95% CI 1.85-2.88). After adjustment for age, job experience, educational level, managerial status, and occupational status (white/blue collar), injury occurrence was significantly elevated for those at level 3 (adjusted odds ratio (OR) = 1.46, 95% CI 1.12-1.91) and level 4 (adjusted OR = 1.81, 95% CI 1.39-2.37) but not for level 2 (adjusted OR = 0.87, 95% CI 0.65-1.18). The authors conclude that adverse work and environmental conditions, objectively assessed, can predict occurrence of occupational injuries.     

Needlestick injury: impact of a recapping device and an associated education program

OBJECTIVE: To determine the impact of the introduction of a plastic shield-shaped device (Needleguard, Biosafe, Auckland, New Zealand) and education program designed to allow safer recapping, on recorded rates of needlestick injury. DESIGN: A before-after trial with a two-year duration of follow-up. SETTING: Tertiary referral hospital. PARTICIPANTS: Nursing and other hospital personnel. RESULTS: Prospectively collected baseline data, together with the results of an anonymous questionnaire of 25% of the hospital nursing staff, defined a reported needlestick injury rate of 6.9 per hundred full-time nursing staff per year. In the pre-intervention period, there were 6.7 needlestick injuries per 100 nursing staff members per year reported. This increased to 15.4 (p less than .0001) needlestick injuries per 100 nursing staff members per year after the intervention. An anonymous survey undertaken at both time periods suggests that the apparent increase in officially reported needlestick injuries is due to an increase in the willingness of nurses to now report previously unreported needlestick injuries. CONCLUSIONS: The impact of the safety device and education program was the more accurate reporting of needlestick injuries; many nursing staff continued to resheath needles contrary to hospital policy. Many staff simply did not use the newly designed safety device. Approaches to improving compliance with such safety devices are considered.

Proton-pump inhibitor use and hip fractures in men: a population-based case-control study

PurposeTo estimate the association between proton-pump inhibitor (PPI) use and hip fracture.MethodsWe conducted a case-control study of 6774 pairs of men aged 45 years or older, matched on age, race, and medical center. Cases sustained incident hip fractures in 1997–2006. Fracture date was index date for each case-control pair. PPI exposure was identified from electronic pharmacy records, 1991–2006. PPI use was measured as (1) ever versus never; (2) adherence; (3) duration; and (4) recentness. Omeprazole and pantoprazole were analyzed separately using conditional logistic regression, adjusted for comorbidities. Nonusers were the referent group.ResultsEight hundred ninety-six (13.2%) cases and 713 (10.5%) controls used omeprazole before index date (matched odds ratio [OR], 1.13; 95% confidence interval [CI], 1.01–1.27). Greatest adherence (medication possession ratio > 80%) (OR, 1.33; 95% CI, 1.09–1.62), highest tertile of duration (OR, 1.23; 95% CI, 1.02–1.48), and recent use (OR, 1.22; 95% CI, 1.02–1.47) were associated with hip fracture. Six hundred ninety-four (10.2%) cases and 576 (8.5%) controls had used pantoprazole (OR, 1.10; 95% CI, 0.97–1.24). Longest duration (OR, 1.25; 95% CI, 1.02–1.53) and most recent use (OR, 1.38; 95% CI, 1.12–1.71) were associated with hip fracture. Our study suggests that PPI use and hip fractures are associated, with risk increasing with longer duration and more recent use.     

Human papillomavirus type 18/16 infection and prevalence among middle-aged and older Chinese rural women: a cross-sectional survey in Wufeng,Hubei Province

This study aimed to measure the prevalence and potential factors related to HPV 16/18 infection among middle-aged and older Chinese rural women. The study was conducted among women aged 35–65 years in rural villages within Wufeng in Hubei Province. Data were collected using a pretested questionnaire between July and August 2015. Cervical specimens were collected for HPV DNA detection and typing by using careHPV. Pearson’s Chi-square and logistic regression analyses were used to examine associations with HPV positivity. Among 1001 participants, the prevalence of HPV 18/16 positive genotyping was 15.88% (n = 159). Husbands’ extramarital sex (adjusted odds ratio [OR] = 15.85, 95% confidence interval [CI] 5.76–43.59), cervicitis (adjusted OR = 9.27, 95% CI 5.06–16.99), condom usage (adjusted OR = 0.16, 95% CI 0.05–0.53), higher average number of live births (adjusted OR = 1.98, 95% CI 1.32–2.96 for two live births; adjusted OR = 3.29, 95% CI 1.39–7.81 for three or more live births) were associated with HPV infection. The prevalence of HPV infection among participating women from rural areas was higher than that in several other areas in China. Our findings can aid efforts to prevent HPV infection to lower the risk of cervical cancer.     

Adherence to dietary guidelines for fruit,vegetables and fish among older Dutch adults; the role of education,income and job prestige

Objectives

Little is known about socio-economic differences in dietary intake among older adults. In this study we describe self-reported dietary adherence to the fruit, vegetables and fish guidelines among older Dutch adults and investigate the independent associations of three socio-economic status (SES) indicators with adherence to these guidelines.

Design

Cross sectional data-analyses.

Settings

The Longitudinal Aging Study Amsterdam (LASA), the Netherlands.

Subjects

1057 community dwelling older adults, aged 55–85 years.

Measurements

Fruit, vegetable and fish intake was assessed using a short food frequency questionnaire. We measured SES using self-reported levels of education, household income and occupational prestige.

Results

82.5% of the respondents reported to adhere to the fruit guideline, 65.1% to the vegetables guideline, and 31.7% to the fish guideline. After adjustment for confounders and the other two SES indicators, respondents in the lowest education group adhered less often to the vegetables guideline (OR 0.39 (95% CI 0.22–0.70)) compared to those in the highest education group. Respondents in the lowest income group adhered less often to the fruit (0.44 (95 % CI 0.22–0.91) and fish guideline (OR 0.55 (95% CI 0.33–0.91) compared to those in the highest groups. Occupational prestige was not independently associated with adherence any the guidelines.

Conclusion

Selfreported adherence to the fruit, vegetables and fish guidelines among older adults can be improved and particularly in those with a low SES. Education and income have independent and unique contributions to dietary adherence. Future research should investigate potential pathways through which these specific SES indicators influence dietary adherence.     

Safety Climate Associated with Adverse Events in Nursing Homes: A National VA Study

Adverse events in health care are leading causes of morbidity and mortality, prompting health care organizations to investigate their antecedents. In nursing homes, safety climate—how staff typically think about safety and act on safety issues—is a potential contributor to adverse events, particularly pressure ulcers, falls, and falls-related injuries. Yet, research to date is equivocal as to whether a more positive safety climate improves safety for residents living in nursing homes. We conducted a cross-sectional analysis of the association between safety climate and adverse events, measured in 2017 and 2018 in 56 VA Community Living Centers (CLCs, or nursing homes) nationwide. Safety climate was measured by the previously validated Community Living Center Employee Survey on Resident Safety (CESARS), completed by nurses, nursing assistants, and clinicians. The CESARS has seven domains: safety priorities, supervisor commitment to safety, senior management commitment to safety, personal attitudes about safety, environmental safety, co-worker interactions around safety, and global rating of CLC; higher CLC-level domain scores indicate better ratings. 2017-18 Minimum Data Set (MDS) measured four CLC-level adverse events: percent of residents who had any falls, major injuries from falls, catheter use, and new/worsened pressure ulcers. Beta-logistic regression models with random effects were used to examine the impact of staff-specific safety climate domain scores on each adverse event, adjusted by year (2017/2018) and CLC-level characteristics (CLC’s operating beds, nursing staffing level, and employee satisfaction/engagement). 1397 and 1645 VA CLC staff responded to the CESARS in 2017 and 2018, respectively. There were significant associations between all four adverse events and three of the safety climate domains: expected, inverse associations with two domains and unexpected associations with one domain (P < .05). Better ratings of supervisor commitment to safety and environmental safety were each associated with lower rates of three out of the four adverse events, as expected. That is, better ratings of supervisor commitment to safety were significantly associated with lower rates of (1) falls (OR 0.33, 95% CI 0.11-0.97, clinicians), (2) major injuries from falls (OR 0.33, 95% CI 0.11-0.97, clinicians), and (3) catheter use (OR 0.42, 95% CI 0.21-0.85, nurses). Better ratings of environmental safety were significantly associated with lower rates of (1) major injuries from falls (OR = 0.48, 95% CI 0.24-0.93, nurses), (2) catheter use (OR 0.55, 95% CI 0.32-0.93, nursing assistants), and (3) pressure ulcers (OR 0.23, 95% CI 0.09-0.61, clinicians). Better global CLC ratings were unexpectedly associated with higher rates of only catheter use. No other safety climate domains had significant associations. In summary, supervisor commitment to safety (eg, supervisor responsiveness to safety concerns) and environmental safety (eg, presence of grab bars in bathrooms) emerged as elements of safety climate central to lower rates of adverse events in nursing homes. The role of safety climate in lower rates of adverse events was observed across all three groups of frontline staff. Our study thus suggests the potential of safety climate to impact resident safety outcomes. Improving environmental design and supervisory practices with frontline staff could reduce adverse events in nursing homes. Department of Veterans Affairs.     

Risk factors associated with serious ski patrol-reported injuries sustained by skiers and snowboarders in snow-parks and on other slopes

BACKGROUND: Over the past years, the rate of injuries sustained at the alpine ski hills in Québec significantly increased. This raises concern over a possible increase in risk of severe injuries associated with snow-park use. The main objective of this study was to examine the severity of injuries sustained by skiers and snowboarders in snow-parks compared with other slopes from 2001 to 2005. METHODS: A case-control study design was used. Subjects were injured skiers and snowboarders who reported to the ski patrol with an injury. Two sets of severely injured cases were defined based on the type of injury and ambulance evacuation. Injured controls were those who did not sustain severe injuries. 50,593 injury report forms were analyzed. A logistic regression analysis was performed to relate the severity of injury to the type of slope used when the injury occurred. All analyses were controlling for age, sex, skill level, helmet use, season, and type of activity. RESULTS: There was evidence to suggest that, for skiers (adjusted OR = 1.36; 95% CI: 1.21-1.53) and snowboarders (adjusted OR = 1.14, 95% CI: 1.05-1.23), participation in a snow-park increased the risk of being evacuated by ambulance. Severe injuries in skiers were also more likely to occur in snow-parks, but snowboarders had similar risk of severe injury in snow-parks and on other slopes. CONCLUSIONS: These results provide evidence that the type of activities performed in snow-parks may increase the risk of sustaining a severe injury compared with participation on other slopes.     

Adherence to the Planetary Health Diet Index and Obesity Indicators in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

The EAT-Lancet Commission has proposed a model diet to improve the health of human beings and that of the planet. Recently, we proposed the Planetary Health Diet Index (PHDI) to assess adherence of the population to this model diet. In this study, we aimed to evaluate adherence to the PHDI and obesity outcomes using baseline data from 14,515 participants in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). The dietary data were assessed using a 114-item FFQ. Body mass index (BMI) and waist circumference (WC) were both used continuously and categorized. Linear and multinomial regression models adjusted for potential confounding factors were performed to assess the relationship between adherence to PHDI and outcomes. An inverse association was observed between adherence to PHDI and obesity indicators. Individuals with high adherence to the PHDI had lower BMI (β−0.50 95% CI−0.73:−0.27) and WC (β−1.70 95% CI−2.28:−1.12) values. They were also 24% less likely to be overweight (OR 0.76 95% CI 0.67:0.85) or obese (OR 0.76 95% CI 0.65:0.88), and they were 14% and 27% less likely to have increased WC (OR 0.86 95% CI 0.75:0.98) or substantially increased WC (OR 0.73 95% CI 0.64:0.83) than those with lower adherence. Our results showed that higher adherence to the PHDI may decrease obesity indicators.

Risk modifying effect of social capital on measures of heavy alcohol consumption, alcohol abuse, harms, and secondhand effects: national survey findings

STUDY OBJECTIVE: To examine associations between social capital and individual risk for alcohol abuse and harms and identify protective effect mechanisms. DESIGN: Multilevel multivariate analysis with individual level data from a national panel survey of drinking and a contextual measure of social capital reflecting college mean aggregate reports of student volunteerism. Outcomes include heavy episodic (binge) drinking, frequent drinking, frequent drunkenness, diagnosable alcohol abuse, intentional drunkenness, acquisition of binge drinking, harms, secondhand effects from others' drinking. SETTING: United States, 119 four year colleges. PARTICIPANTS: Representative samples of youth ages 18-24 surveyed in 1997 and 1999 using an anonymous mailed questionnaire (total n = 27 687). MAIN RESULTS: Students from colleges with higher levels of social capital reported reduced risks for binge drinking (adjusted OR 0.38, 95% CI 0.20 to 0.69, p = 0.002), frequent drunkenness (adjusted OR 0.58, 95% CI 0.34 to 0.98, p = 0.04), acquisition of binge drinking in college (adjusted OR 0.48, 95% CI 0.24 to 0.95, p = 0.03), and alcohol abuse (adjusted OR 0.55, 95% CI 0.34 to 0.91, p = 0.02) in multilevel multivariate analyses that controlled for individual volunteering, the measure on which social capital was based. Higher levels of social capital protected against multiple drinking related harms (adjusted OR 0.51, 95% CI 0.29 to 0.90, p = 0.02) and secondhand drinking effects (adjusted OR, 0.30, 95% CI 0.16 to 0.58, p = 0.0003). Significant cross level interactions exist between fraternity/sorority membership and social capital for measures of risky drinking. Harm reduction primarily reflects consumption modification. CONCLUSIONS: Social capital exerts strong protective effects on alcohol abuse and harm in college including among high risk students.
