HIV and interventional radiology: a national survey of physician attitudes and behaviors.

PURPOSE: The frequency of parenteral and cutaneous exposure to blood or body fluid during interventional radiologic procedures, current use of barrier precautions by interventional radiologists, and physician attitudes about testing for the human immunodeficiency virus (HIV) and related issues were assessed. MATERIALS AND METHODS: An anonymous survey of interventional radiologists was conducted by mail in November 1991. RESULTS: Of 1,530 surveys, 819 (54%) were returned and 806 (53%) were completed and evaluable. Ninety-six percent of respondents (763 of 794) perform procedures in patients infected with HIV. Sixty-nine percent oppose mandatory testing of physicians for HIV. Eighty-seven percent (693 of 797) reported at least one procedure-related injury (range, 0-99; mean, four). Fifty-eight percent of injuries occurred with use of a sharp instrument (381 of 662), 20% were due to needle recapping (133 of 662), and 7% (44 of 662), to improper disposal of a sharp instrument. Contact between a physician's blood and a patient was reported in only one case (0.2%). Eighty-five percent of respondents (671 of 789) changed their use of barrier precautions in the last 10 years; concerns about HIV were cited by 96% as a reason for change. Reported use of barrier measures was highly variable. CONCLUSION: Exposure to patients' blood or body fluid is not infrequent during interventional radiologic procedures. Exposure of patients to the blood or body fluid of health care workers is rare. Use of recommended precautions in interventional radiology is variable, and practices that could lead to preventable injury remain common. Strategies should be developed to reduce risks even further and to encourage universal compliance with government guidelines.

Extended work duration and the risk of self-reported percutaneous injuries in interns.

CONTEXT: In their first year of postgraduate training, interns commonly work shifts that are longer than 24 hours. Extended-duration work shifts are associated with increased risks of automobile crash, particularly during a commute from work. Interns may be at risk for other occupation-related injuries. OBJECTIVE: To assess the relationship between extended work duration and rates of percutaneous injuries in a diverse population of interns in the United States. DESIGN, SETTING, AND PARTICIPANTS: National prospective cohort study of 2737 of the estimated 18,447 interns in US postgraduate residency programs from July 2002 through May 2003. Each month, comprehensive Web-based surveys that asked about work schedules and the occurrence of percutaneous injuries in the previous month were sent to all participants. Case-crossover within-subjects analyses were performed. MAIN OUTCOME MEASURES: Comparisons of rates of percutaneous injuries during day work (6:30 am to 5:30 pm) after working overnight (extended work) vs day work that was not preceded by working overnight (nonextended work). We also compared injuries during the nighttime (11:30 pm to 7:30 am) vs the daytime (7:30 am to 3:30 pm). RESULTS: From a total of 17,003 monthly surveys, 498 percutaneous injuries were reported (0.029/intern-month). In 448 injuries, at least 1 contributing factor was reported. Lapse in concentration and fatigue were the 2 most commonly reported contributing factors (64% and 31% of injuries, respectively). Percutaneous injuries were more frequent during extended work compared with nonextended work (1.31/1000 opportunities vs 0.76/1000 opportunities, respectively; odds ratio [OR], 1.61; 95% confidence interval [CI], 1.46-1.78). Extended work injuries occurred after a mean of 29.1 consecutive work hours; nonextended work injuries occurred after a mean of 6.1 consecutive work hours. Injuries were more frequent during the nighttime than during the daytime (1.48/1000 opportunities vs 0.70/1000 opportunities, respectively; OR, 2.04; 95% CI, 1.98-2.11). CONCLUSION: Extended work duration and night work were associated with an increased risk of percutaneous injuries in this study population of physicians during their first year of clinical training.

Spinal cord infarction due to a self-inflicted needle stick injury.

STUDY DESIGN: Case report. OBJECTIVE: To report a case of spinal cord infarction after a self-inflicted needle stick injury, following an injection of heroin into the cord. SETTING: National spinal injury unit in a Scottish University teaching hospital, Glasgow, UK. CASE REPORT: A 20-year-old male, injected street heroin accidentally into the cord through the left side of the neck, leading to sudden loss of power to all four limbs. Initial magnetic resonance imaging scans showed extensive cord oedema and follow-up scans showed signal changes within the anterior horns of the spinal cord in keeping with a cord infarct. CONCLUSION: Self-inflicted spinal cord injury with a small needle is difficult, but not impossible. Cord infarct as a result of a self-inflicted injury has not been previously reported. The mechanism of the injury resulting in cord infarction is explained by the vascular anatomy of the spinal cord circulation, and this may also explain the residual neurological status of the patient.

The effectiveness of a needleless intravenous connection system: an assessment by injury rate and user satisfaction.

OBJECTIVE: To assess the impact of a needleless intravenous (i.v.) connection system on the rate of reported intravenous-connection-related (IVCR) percutaneous injuries, and to assess user satisfaction, frequency of use, and barriers to use. DESIGN: A pre-post intervention design, with injury incidence rates being compared 3 years before and 1 year after hospital wide device implementation; and a cross-sectional descriptive user satisfaction survey. SETTING: Two tertiary-care teaching hospitals, one general and one pediatric, located in a large metropolitan medical center. OUTCOME VARIABLE: All IVCR percutaneous injuries reported to the employee health services at both hospitals during the years from 1989 to 1991 and 1993. STUDY POPULATION: Survey participants were selected randomly from licensed nursing employees at both hospitals. INTERVENTION: i.v. connection system consisting of blunt plastic cannulas and compressed latex injection sites. RESULTS: After device implementation, the IVCR injury rate was reduced 62.4% (rate ratio [RR], 0.38; 95% confidence interval [CI95], 0.27-0.53) at the general hospital and 70.2% (RR, 0.30; CI95, 0.17-0.53) at the pediatric hospital. After adjusting for the reduction in injury rate due to factors other than device implementation, the IVCR injury rate was reduced 54.5% (adjusted RR, 0.46; CI95, 0.32-0.65) at the general hospital and 57.2% (adjusted RR, 0.43; CI95, 0.24-0.78) at the pediatric hospital. Approximately 94% of survey respondents (n = 478, response rate = 51%) were satisfied with the device and recommended continued use. However, needles still were being used for activities that could have been performed with the needleless system because of compatibility, accessibility, and other technical problems related to the device. CONCLUSIONS: The device was effective in reducing the rate of reported IVCR percutaneous injuries and users were satisfied with the device, but barriers to universal use were identified.

[Occupational injuries with risk of transmission of blood-borne pathogens. A study of a 2-year material from the Holstebro Central Hospital].

In order to illuminate causes of accidental occupational exposure of the house staff at the Central Hospital of Holstebro (CHH) to the potential hazards of HIV- and HBV-transmission, all cases of reported injuries occurring in 1991-1992 have been analysed. Needleprick lesions were found to account for the great majority of the reported cases (71%). Sixty-six percent of all injuries were self-inflicted during medical procedures, while 34% were caused by another person, either directly (simultaneous contact of two persons with the contaminated sharp object) or indirectly as a result of carelessness or negligence. Seventy-two percent of the analysed exposures could have been avoided if the staff had complied with Universal Precautions recommended since 1988. In order to estimate the amount of unreported cases, all nurses and laboratory technicians currently employed at CHH were asked to complete an anonymous questionnaire reviewing their past (1991-1992) mucocutaneous and percutaneous exposures to blood or body fluids. Only 28% of the injuries recalled by the subjects had been reported. If the risk of occupational transmission of blood-borne diseases is to be minimized, additional effort must be made to clarify the principles of the Universal Precautions policy. It is of great importance that all injuries are reported by way of an easy reporting procedure which is efficient and familiar to the staff at any time.

Temporal association between implementation of universal precautions and a sustained, progressive decrease in percutaneous exposures to blood.

To evaluate whether implementation of universal precautions was temporally associated with a decrease in reported parenteral exposures to blood, we analyzed data on self-reported parenteral injuries that were prospectively collected at the Clinical Center, National Institutes of Health (Bethesda, MD), from 1985 through 1991. We also assessed whether implementation of universal precautions, in concert with initiation of a program of postexposure chemoprophylaxis with zidovudine, was associated with decreased time to reporting of occupational exposures. Our data, possibly confounded by the occurrence of an occupational infection due to human immunodeficiency virus infection in 1988, nonetheless demonstrate a temporal association between a progressive, significant decrease in percutaneous injuries and the implementation of universal precautions that has been sustained through subsequent years. The analysis remains significant, regardless of the surrogate denominator chosen for analysis. No trend toward more rapid reporting of exposures was identified. Implementation of universal precautions appears to have contributed to decreased parenteral injuries in our hospital but did not affect reporting efficiency.

Transmission of HIV-1 from an obstetrician to a patient during a caesarean section.

We describe a probable case of HIV-1 transmission from a healthcare worker (HCW) to a patient during a caesarean section. Genetic distance comparisons of the viral sequence of the C2V4 region of the viruses from the patient and the obstetrician showed an average nucleotide sequence divergence of 3% (2.8-3.1). HIV can be transmitted from an infected HCW to a patient when percutaneous injuries with subsequent exposure of the patient to the blood of the HCW can occur.

Sharpless surgery: a prospective study of the feasibility of performing operations using non-sharp techniques in an urban, university-based surgical practice.

CONTEXT: Percutaneous injuries occur frequently during surgical procedures and represent a significant occupational hazard to operating room personnel. OBJECTIVES: To evaluate the feasibility of performing select general surgical procedures using a combination of non-sharp devices and techniques to replace the conventional use of scalpels and needles. DESIGN, SETTING, AND PARTICIPANTS: Candidate procedures for which sharpless techniques could replace conventional scalpels and suture needles were identified preoperatively in an urban, university-based general surgical practice over a 1-year period (June 2003-June 2004). Non-sharp techniques included monomeric 2-octyl cyanoacrylate adhesive, electrocautery, tissue stapler, and minimally invasive instrumentation. Conventional scalpels and suture needles were readily available and used whenever necessary. MAIN OUTCOME MEASURES: We rated the feasibility of performing specific procedures without sharps. We also documented the rate of overall reversion to sharps during operations on patients that had been identified preoperatively as candidates for sharpless surgery. RESULTS: Of 358 procedures performed in the general surgery university practice, 91 were identified preoperatively as appropriate for sharpless surgery. Of these, 86.8% (79/91) were completed without the use of sharps, including 13/22 (59.1%) open laparotomy procedures, 20/22 (90.9%) laparoscopic procedures, and 46/47 (97.8%) soft tissue procedures. Intraoperative reversion to sharps occurred in 12 cases when deemed necessary by the surgeon. CONCLUSIONS: Select common procedures can be performed entirely with sharpless techniques, eliminating the risk to surgical personnel associated with intraoperative percutaneous injuries.

Evaluation of a safety resheathable winged steel needle for prevention of percutaneous injuries associated with intravascular-access procedures among healthcare workers.

OBJECTIVE: To compare the percutaneous injury rate associated with a standard versus a safety resheathable winged steel (butterfly) needle. DESIGN: Before-after trial of winged steel needle injuries during a 33-month period (19-month baseline, 3-month training, and 11-month study intervention), followed by a 31-month poststudy period. SETTING: A 1,190-bed acute care referral hospital with inpatient and outpatient services in New York City. PARTICIPANTS: All healthcare workers performing intravascular-access procedures with winged steel needles. INTERVENTION: Safety resheathable winged steel needle. RESULTS: The injury rate associated with winged steel needles declined from 13.41 to 6.41 per 100,000 (relative risk [RR], 0.48; 95% confidence interval [CI95], 0.31 to 0.73) following implementation of the safety device. Injuries occurring during or after disposal were reduced most substantially (RR, 0.15; CI95, 0.06 to 0.43). Safety winged steel needle injuries occurred most often before activation of the safety mechanism was appropriate (39%); 32% were due to the user choosing not to activate the device, 21% occurred during activation, and 4% were due to improper activation. Preference for the safety winged steel needle over the standard device was 63%. The safety feature was activated in 83% of the samples examined during audits of disposal containers. Following completion of the study, the safety winged steel needle injury rate (7.29 per 100,000) did not differ significantly from the winged steel needle injury rate during the study period. CONCLUSION: Implementation of a safety resheathable winged steel needle substantially reduced injuries among healthcare workers performing vascular-access procedures. The residual risk of injury associated with this device can be reduced further with increased compliance with proper activation procedures.

An investigation of the disposal of dental clinical waste in Bangkok.

This study investigated the disposal of clinical waste within dental surgeries in Bangkok, Thailand and followed the waste trail to the rubbish tips. A questionnaire was sent to all dental practices in the Bangkok Metropolitan Area. The response rate was 57.7 per cent. At the same time, rubbish collectors and scavengers were interviewed to see if they encountered clinical dental waste. Few dentists complied with all recommendations for the disposal of waste. Most waste was disposed of into the domestic rubbish stream. Rubbish collectors and scavengers knew what dental rubbish looked like and some had had needle-stick injuries. Although recommendations can be made to the dental profession to alter their behaviour, real improvement is unlikely without changes to legislation and social policy.

Healthcare workers' knowledge of inoculation injuries and glove use.

Healthcare workers' (HCWs') occupational risk of exposure to blood-borne pathogens has been well documented. Subsequent educational programmes, awareness campaigns and policy implementation made limited impact on HCWs' level of knowledge of these risks and compliance with universal precautions. Two hundred HCWs completed a questionnaire to evaluate their level of knowledge. Results demonstrated that despite a comprehensive educational programme for nurses and training for medical staff, knowledge of inoculation injuries and associated issues remained inadequate. Indeed, policies and procedures were not followed. Furthermore, gloves were not routinely worn in the clinical setting. Educational programmes ware essential to inform HCWs of occupational risk of exposure to blood-borne pathogens and guide practice following an inoculation injury. However, efficacy of such programmes must be reviewed, alternative strategies evaluated, and the cause of HCWs' limited knowledge determined.

Creating a safer workplace to provide quality care.

In recent years, increasing interest has been placed on how health care workers can be trained and equipped to better protect them from possible workplace accidents and injuries while improving the care they deliver. Better workplace safety also means better customer and employee satisfaction, improved workforce retention and recruitment, and cost savings. Workplace safety is constantly evolving and addresses a whole host of issues ranging from needles and sharps injuries to moving patients to human factor analyses. This issue takes a cross-sectional look at how hospitals and health systems are addressing problem areas--and sharing information and best practices--to strengthen their quality of care at the workplace level.

Reducing percutaneous injuries in the OR by educational methods.

Exposure to bloodborne pathogens (e.g., HIV, hepatitis B, hepatitis C) through percutaneous injuries is an occupational risk for health care workers, especially those in the OR. The incidence of disease continues to rise, although occupational exposures often go unreported. Percutaneous injury prevention methods have included use of safety devices, practice changes, and educational programs. An educational intervention to increase awareness of risk, provide suggestions for injury reduction, and encourage reporting of exposures was performed at a university teaching hospital. Preliminary qualitative results show increased exposure reporting, increased use of personal protective equipment, and increased awareness of disease exposure risk among OR personnel.

Changing knowledge, attitudes, and practices of Thai oral health personnel with regard to AIDS: an evaluation of an educational intervention.

OBJECTIVE: This study evaluated the effect of an educational intervention in improving Thai oral health personnel's (OHP) knowledge, attitudes and practices (KAP) regarding HIV/AIDS. RESEARCH DESIGN: The study used a pre-test/post-test design with study and control groups. RESULTS: of the pre-test questionnaire were used to design the intervention. Three months after the study group received the intervention, the same questionnaire was given to both groups. INTERVENTION: A three-day workshop was conducted using a variety of teaching methods: lectures, videos, role-plays, interviews with HIV infected persons, and demonstrations. SETTING: The study was conducted in rural government dental clinics in three provinces in southern Thailand. One hundred and three OHP in 23 dental clinics were in the study group while 46 OHP in II dental clinics were in the control group. OUTCOME MEASURES: The outcomes were knowledge and attitudes regarding HIV/AIDS, perception of occupational risk, willingness to treat HIV infected persons and adherence to recommended infection control procedures. RESULTS AND CONCLUSIONS: The educational intervention resulted in significant improvement in many domains of KAP in the study group, while there was little change in the control group. The post-test questionnaire showed that further improvements are needed in attitudes towards HIV/AIDS and practices regarding accidental needle stick injury. The intervention was both effective and appropriate and should be considered for national use.

Evaluation of a needle-free intravenous access system.

Needle-stick injuries are one of the most severe hazards faced by nurses today. The most physically and emotionally devastating type of injury is from a needle contaminated with human immunodeficiency virus (HIV), but far more likely to occur is infection with other blood-borne pathogens, especially hepatitis B. The daily threat of needle-stick injuries adds yet another dimension of concern to the stresses inherent in working in a health care facility. Health care workers at greatest risk are those who manipulate needles and draw blood samples on a regular basis. With this concern in mind, a study was launched to evaluate a needle-free I.V. access system with respect to the following research objectives: 1) to assess the prevention/reduction of needle-stick risks and injuries; 2) to identify associated reduction in expenses; 3) to implement product and ease of use; and 4) to assess nursing satisfaction levels. This article describes the methodology used and the results of the study.

Injection safety and Indian Academy of Pediatrics.

A major proportion of injections administered in India are unsafe. Unsafety is due to (1) steps that are associated with increased risk of spread of blood borne viruses and (2) errors related to technique of injection and faulty habits. Recommendations of Indian Academy of Pediatrics revolve round the following points: Equipment related, safe injection practices, best injection techniques, rational injection practices, prevention of needle stick injuries and reducing disease transmission recommendation for HIV-PEP (postexposure prophylaxis), HBV-PEP, disposal of syringes and sharps. The points have been discussed elaborately.

Occupational exposures to blood among emergency medicine residents.

OBJECTIVES: To investigate the epidemiologic characteristics of potentially infectious occupational exposures to blood among emergency medicine (EM) residents. METHODS: A SAEM-sponsored multiple-choice survey was administered anonymously to all EM residents participating in the 1998 American Board of Emergency Medicine in-service examination. Survey questions included resident demographics, use of universal precautions, frequency and types of exposures to blood, and exposure reporting. Residents who experienced at least one exposure were then asked to complete an additional set of questions referring only to their latest exposure. Mean values were calculated for each variable and differences between groups were compared by chi-square analysis. RESULTS: Three thousand one hundred sixty-two surveys were distributed to the resident participants, and 2,985 surveys (94.4%) were returned. Of the participants, 56.1% reported at least one exposure to blood during their EM training. The frequency of this self-reported exposure increased with advancing EM level of training (43% EM-1, 58% EM-2, 64% EM-3, 76% EM-4, p<0.001). Of these residents, 36.6% always followed universal precautions, 54% frequently, and 9.4% sometimes, rarely, or never. Those individuals who "always" followed universal precautions reported significantly fewer exposures than those who did not (p<0.005). The latest exposures were most commonly caused by a solid needle or sharp object (39.4%), by a hollow-bore needle (30.6%), or by eye splashes (17.2%). Of these exposures, 71.7% occurred in the ED setting, and only 46.7% of these exposures were reported to health care providers. CONCLUSION: Emergency medicine residents are frequently exposed to blood, most commonly due to puncture injuries by sharp objects. The rate of exposure reporting is low, which may compromise appropriate postexposure counseling and prophylaxis.
