This cross-sectional study of home care aides examines self-reported occupational exposure to blood and body fluids to determine if factors that place these workers at risk can be identified. Home care aides working for two agencies in the Chicagoland area were surveyed. A total of 62 (6.3%) of the home care aides reported instances of blood and body fluid exposure either via sharps or mucous membrane contact. Although few aides reported performing health care-related tasks such as colostomy care, caring for a urinary catheter, or bowel stimulation (which were outside their scope of duties), those who did were significantly more likely to experience blood and body fluid exposure (p≤.01). Level of assistance needed by clients in tasks such as feeding, laundry, and transportation was also found to be significantly associated with blood and body fluid exposure (p≤.01). These data highlight the importance of, and need for, home care aid training in the use of universal precautions. 相似文献

Aim To study the epidemiology and time trends of blood and bodyfluids (BBF) exposures among hospital doctors. Methods A 3-year study was carried out using data from the ExposurePrevention Information Network of four teaching hospitals inthe UK. Results One hundred and seventy-five cases of BBF exposuresin doctors were reported over the 3-year study period. Eighty-one(46%) occurred in senior doctors and 94 (54%) in junior doctors.Junior doctors had a higher rate of BBF exposures compared tosenior doctors: 13 versus 4 incidents per 100 person-years,respectively (relative risk 3, 95% confidence interval 2–4).The most frequent setting for BBF exposures among senior doctorswas the operating theatre/recovery (59%). Among junior doctors,it was the patient room (48%). The commonest original reasonfor use of sharps by junior doctors was the taking of bloodsamples (42%). Among senior doctors, it was suturing (41%). Conclusion While ongoing training efforts need to be directedtowards both junior and senior doctors, our data suggest thatjunior doctors are at higher risk of BBF exposures and may needparticular attention in prevention strategies. An improvementin the safety culture in teaching hospitals can be expectedto reduce the number of BBF exposures. 相似文献

A survey was undertaken of all isolations of methicillin-sensitive and methicillin-resistant Staphylococcus aureus (MRSA) at a large Australian teaching hospital over a 12 month period. All methicillin-resistant isolations obtained from the Casualty and Outpatient clinics were from staff members or patients with recent hospital contact. Twenty per cent of all methicillin-resistant isolations from in-patients were from specimens taken within 2 days of the patient's admission. Each of these patients had had hospital contact within the previous 4 months and it is assumed that the majority of them reintroduced the organism into the hospital. Such patients may provide an important means by which infection control procedures are bypassed. Patients who were relatively more likely to become infected or colonized with methicillin-resistant than with methicillin-sensitive strains included the elderly and those with postoperative wound infections (especially after orthopaedic or vascular surgery), spinal injuries, peripheral vascular disease, chronic skin ulcers or chronic diseases of the respiratory or urinary tracts. Eleven per cent of MRSA wound isolates and 15 per cent of sputum isolates were associated with serious infections requiring specific treatment, emphasizing the ability of these strains to produce serious illness. A small proportion of staff and asymptomatic patients were found to harbour MRSA and the importance of these individuals in facilitating cross-infection requires further investigation. 相似文献

Recent community studies have suggested that low level lead exposure is significantly associated with blood pressure in the general population. This finding is inconsistent with the results of recent occupational studies of lead exposed workers, although the occupational studies contained serious methodological weaknesses. The present study examined the relation between occupational lead exposure and diastolic and systolic blood pressure in randomly selected samples of 270 exposed and 158 non-exposed workers. Four exposure indicators were examined: employment at a lead battery plant nu a control plant, current blood lead value, current zinc protoporphyrin value, and time weighted average blood lead value. After controlling for other known risk factors such as age, education, income, cigarette usage, alcohol consumption, and exercise, the associations between exposure and blood pressure were small and non-significant. In the absence of a biologically feasible hypothesis regarding the mechanism by which low level lead exposure would influence blood pressure the present findings challenge the validity of the general population association. 相似文献

The epidemiology of influenza in the hospital is frequently confounded by failure to separate community-acquired from nosocomial transmission. An 83-year-old woman was hospitalized one day after returning from Asia with complications resulting from acute influenza A (H3N2) infection; she was the first culture-confirmed case in the region during the 1987-1988 influenza season, and her illness antedated other influenza cases in the area by at least four weeks. The patient shed virus at least four days after admission and transmitted influenza to her primary physician; both had received trivalent influenza vaccine four weeks earlier. Surveillance data from the 28 health care providers (HCPs) in contact with the index case (mean age: 34.5 years; median time of contact: four hours, none receiving vaccine) revealed no evidence of transmission as detected by paired type-specific complement-fixation antibodies and throat culture (20 subjects) or acute serologies and culture (7 subjects). No febrile respiratory illnesses were detected among other patients on the same ward, although three were reported among HCPs. Thus, neither secondary spread of influenza from infected patient to hospital HCPs nor nosocomial transmission apparently took place, although transmission did occur to the primary physician. 相似文献

This paper summarizes the analytical and occupational hygiene findings from a recent survey of occupational exposure to metalworking fluids (MWFs) in the engineering industry. The aim of the survey was to link MWF mist exposure measurements with particular engineering processes and controls, and utilize the data obtained to develop exposure standards. At the same time the opportunity was taken to assess fluid management and control, including bacterial and fines contamination in the machine sumps. In general, occupational exposure to mineral oil MWF mist was controlled to <3 mg/m(3) (8 h time-weighted average) and to <1 mg/m(3) for water-mix MWF mist (in terms of the concentrate). These exposure values do not necessarily represent best practice, but are believed to be achievable and representative of industry as a whole. Gravimetric analysis of the total inhalable particulate was found to be a good predictor of mineral oil MWF mist but not for water-mix MWF mist. Grinding and drilling operations produced higher exposures than turning and milling for water-mix fluids. There were insufficient data to compare machining operations for mineral oil MWFs. On the whole, fluid management was found to be poor, with most sites failing to meet industry good practice or Health & Safety Executive (HSE) standards. Some of the operating procedures utilized were deficient or unsatisfactory. Poor standards of fluid management were found at all sizes of company. High levels of bacteria, endotoxin and fines were found in sumps, and control of other factors, such as water-mix fluid concentration, was often poor. Mineral oils had higher levels of fines than water-mix fluids (medians of 395 and 18 mg/l, respectively), and grinding produced high levels of fines in both types of MWF. Many water-mix sumps contained bacterial levels of >1 x 10(6) CFU/ml, and endotoxin levels of >100 000 EU/ml were not uncommon. The median values were 109 000 CFU/ml and 8039 EU/ml, respectively. Mists could potentially contain extensive contamination from bacteria and endotoxin. Analysis of the data suggests that sumps operating under typical conditions for machining (a temperature of 20 degrees C, a pH of 9 and a fluid strength below 10%), also appear to provide optimum conditions for the proliferation of bacteria. Low levels of benzo[a]pyrene (median 0.03 micro g/g) were found in the mineral oils, and low levels of N-nitrosodiethanolamine (median 0.4 micro g/ml) were found in the water-mix MWFs. The results of this work will contribute to guidance from the HSE, setting out accepted industry good practice, including guide values for MWF mist and sump fluid contaminants, with significant emphasis on sump fluid management (maintenance and monitoring), as well as control issues. 相似文献

OBJECTIVE: To describe hospital practices and policies relating to bloodborne pathogens and current rates of occupational exposure among healthcare workers. PARTICIPANTS AND METHODS: Hospitals in Iowa and Virginia were surveyed in 1996 and 1997 about Standard Precautions training programs and compliance. The primary outcome measures were rates of percutaneous injuries and mucocutaneous exposures. RESULTS: 153 (64%) of 240 hospitals responded. New employee training was offered no more than twice per year by nearly one third. Most (79%-80%) facilities monitored compliance of nurses, housekeepers, and laboratory technicians; physicians rarely were trained or monitored. Implementation of needlestick prevention devices was the most common action taken to decrease sharps injuries. Over one half of hospitals used needleless intravenous systems; larger hospitals used these significantly more often. Protected devices for phlebotomy or intravenous placement were purchased by only one third. Most (89% of large and 80% of small) hospitals met the recommended infection control personnel-to-bed ratio of 1:250. Eleven percent did not have access to postexposure care during all working hours. Percutaneous injury surveillance relied on incident reports (99% of facilities) and employee health records (61%). The annual reported percutaneous injury incidence rate from 106 hospitals was 5.3 injuries per 100 personnel. Compared to single tertiary-referral institution rates determined more than 5 years previously, current injury rates remain elevated in community hospitals. CONCLUSIONS: Healthcare institutions need to commit sufficient resources to Standard Precautions training and monitoring and to infection control programs to meet the needs of all workers, including physicians. Healthcare workers clearly remain at risk for injury. Further effective interventions are needed for employee training, improving adherence, and providing needlestick prevention devices. 相似文献

Summary The occupational exposure to cyclophosphamide (CP), ifosfamide (IF), 5-fluorouracil (5FU), and methotrexate (MTX) of 25 pharmacy technicians and nurses from four departments of a hospital was investigated. Previously developed methods for the detection of exposure to some antineoplastic agents were validated. Exposure to CP, IF, 5FU, and MTX was measured by the analysis of these compounds in the environment (air samples and wipe samples from possible contaminated surfaces and objects). Contamination of the work environment was found not only on the working trays of the hoods and on the floors of the different rooms but also on other objects like tables, the sink unit, cleaned urinals and chamber pots, and drug vials and ampules used for preparation and packing of drugs. The gloves used during preparation of the drugs and during cleaning of the hoods were always contaminated. The uptake of CP or IF was determined by the analysis of both compounds in urine. CP or IF was detected in the urine of eight pharmacy technicians and nurses. The amounts ranged from < 0.01 to 0.5 g (median: 0.1 g). CP and IF were found not only in the urine of pharmacy technicians and nurses actively handling these compounds (n = 2) but also in the urine of pharmacy technicians and nurses not directly involved in the preparation and administration of these two drugs (n = 6). CP and IF were excreted during different periods ranging from 1.40 to 24.15 h after the beginning of the working day, suggesting different times of exposure, different exposure routes, and/or interindividual differences in biotransformation and excretion rate for these compounds. The urinary CP and IF determination method seems to be sensitive and suitable for monitoring the exposure to and measuring the uptake of these toxic compounds by pharmacy technicians and nurses during occupational activities. 相似文献

Health care workers (HCWs) risk occupational exposure to bloodborne pathogens. Effective postexposure treatment and testing depend on compliance with follow-up, but compliance rates are poorly understood. We examined trends in exposure and follow-up at a large teaching hospital after interventions to improve compliance. We reviewed exposures from October 1987 to September 1988 (group 1) and July 1996 to June 1997 (group 2). Data were analyzed for HCW demographics, source patient characteristics, and follow-up outcomes. We found that group 2 source patient serologic data were obtained more often. Group 1 source patients were more likely to be positive for the human immunodeficiency virus (HIV). Group 2 HCWs were more likely to be immune to hepatitis B virus, to agree to HIV testing, and to comply with follow-up. Follow-up rates remained suboptimal, even after high-risk exposures. Non-licensed HCWs were less likely to accept postexposure testing than physicians or nurses in group 2. General and targeted interventions to improve compliance and follow-up are still needed. 相似文献
