Costs and benefits of measures to prevent needlestick injuries in a university hospital.

OBJECTIVE: To document the costs and the benefits (both in terms of costs averted and of injuries averted) of education sessions and replacement of phlebotomy devices to ensure that needle recapping did not take place. DESIGN: The percentage of recapped needles and the rate of needlestick injuries were evaluated in 1990 and 1997, from a survey of transparent rigid containers in the wards and at the bedside and from a prospective register of all injuries in the workplace. Costs were computed from the viewpoint of the hospital. Positive costs were those of education and purchase of safer phlebotomy devices; negative costs were the prophylactic treatments and follow-up averted by the reduction in injuries. SETTING: A 1,050-bed tertiary-care university hospital in the Paris region. RESULTS: Between the two periods, the proportion of needles seen in the containers that had been recapped was reduced from 10% to 2%. In 1990, 127 needlestick (12.7/100,000 needles) and 52 recapping injuries were reported versus 62 (6.4/100,000 needles) and 22 in 1996 and 1997. When the rates were related to the actual number of patients, the reduction was 76 injuries per year. The total cost of information and preventive measures was $325,927 per year. The cost-effectiveness was $4,000 per injury prevented. CONCLUSION: Although preventive measures taken to ensure reduction of needlestick injuries appear to have been effective (75% reduction in recapping and 50% reduction in injuries), the cost of the safety program was high.     

Prevalence of nosocomial infections in a Saudi Arabian teaching hospital.

The rate of nosocomial infections was determined during a 9-month study in a 6-year-old hospital in north Saudi Arabia. The overall rate of nosocomial infection in the hospital was 2.2%. The rates in the different services varied. The highest were in the Special Care Baby Unit (13.5%) and Intensive Care Unit (6%). In the other services it ranged from 1 to 3.5%. The common causal agents of documented infections were Escherichia coli (81), Pseudomonas aeruginosa (55), Staphylococcus aureus (43), Klebsiella spp. (23), Candida spp. (15), Proteus spp. (14), enterococci (13), Enterobacter spp. (7), Acinetobacter spp. (2) and Providencia sp. (1). The most commonly infected sites from which these organisms were isolated were urine (133), wounds (48), umbilical cord (18), high vaginal infection (13), blood (11), burn respiratory tract infection (10 each).     

Effects of hospital staffing and organizational climate on needlestick injuries to nurses

OBJECTIVES: This study determined the effects of nurse staffing and nursing organization on the likelihood of needlestick injuries in hospital nurses. METHODS: We analyzed retrospective data from 732 and prospective data from 960 nurses on needlestick exposures and near misses over different 1-month periods in 1990 and 1991. Staffing levels and survey data about working climate and risk factors for needlestick injuries were collected on 40 units in 20 hospitals. RESULTS: Nurses from units with low staffing and poor organizational climates were generally twice as likely as nurses on well-staffed and better-organized units to report risk factors, needlestick injuries, and near misses. CONCLUSIONS: Staffing and organizational climate influence hospital nurses' likelihood of sustaining needlestick injuries. Remedying problems with understaffing, inadequate administrative support, and poor morale could reduce needlestick injuries.     

Update of the cost of needlestick injuries in hospital healthcare personnel

OBJECTIVES: To update the mean cost of each hepatitis B, hepatitis C and HIV follow-up in health personnel accidentally exposed to blood and body fluids, to stratify the cost depending on the serological status of the source, and to identify the items that account for the main part of the cost. METHODS: A cost analysis was carried out. The postexposure program was modeled on a decision tree combining probabilities (percentage of each type of source depending on positivity for the three viruses and immunization status of the health worker against hepatitis B) and monetary costs (euros in 2002). Costs included salaries, laboratory, pharmacy (including postexposure prophylaxis), water, gas and electricity, cleaning, telephone, medical and office equipment, amortization and lost productivity. RESULTS: The mean cost was 388 euros, ranging from 1,502 euros (source positive for hepatitis C and HIV) to 172 euros (source negative for the three viruses). If the source was hepatitis B positive, the mean cost was 666 euros when the injured worker was not immunized and was 467 euros if the worker was immunized. Serologic tests and postexposure prophylaxis accounted for the main part of the cost. CONCLUSIONS: The high cost suggests the need for appropriate risk evaluation to avoid unnecessary follow-ups. The model used allows the cost of each potentially avoidable episode to be determined and could be used in any hospital to perform an economic evaluation of new preventive devices.     

Prevalence of antimicrobial resistance in Acinetobacter calcoaceticus-baumannii complex in a Saudi Arabian hospital.

During the period from 1998 through 2004, a total of 476 isolates of Acinetobacter calcoaceticus-baumannii complex were recovered. The organism showed high rates of resistance to ampicillin (86% of isolates), cefoxitin (89%), and nitrofurantoin (89%). The rate of resistance to imipenem was 3%; to ticarcillin-clavulanic acid, 16.5%; to gentamicin, 26%; and to ceftazidime, 38%. Multidrug resistance was observed in 14%-35.8% of Acinetobacter species isolates.     

Reported needlestick and sharp injuries among health care workers in a Greek general hospital

Between July 1990 and June 1996, 284 exposures to infectious material were reported by 247 health care workers (HCWs) at AHEPA University Hospital, Thessaloniki, Greece, representing an overall rate of 2.4% reported injuries per 100 HCWs/year. Nurses reported the highest rates of incidents (3.0%) and in all but one working group women exhibited higher injury rates per year than male HCWs. Young workers (21-30 years old) were primarily affected in incidents (P < 0.001). Needles were the most common implement causing injury (60.6%) and resheathing of used needles as well as garbage collection were common causes of injury. None of the HCWs seroconverted in exposures where immune status to blood-borne pathogens was estimated. Efforts by the infection control committee need to be more intense, in order to increase the rate of reported staff injuries. This will facilitate identification of unsafe practices and provide more adequate preventive measures.     

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.     

Occupational needlestick injuries in a metropolitan police force

OBJECTIVES: Police officers are at risk of bloodborne diseases through needlestick injuries but few studies have addressed this problem. The purpose of this study was to assess the risk of needlestick injuries in law enforcement officers and to determine predictors of injuries and reporting rates. DESIGN: An anonymous, voluntary questionnaire was distributed to 1738 active-duty, metropolitan police officers. The survey included the number of needlestick injuries ever experienced, how often these were reported, activities at the time of injury and attitudes toward injuries. RESULTS: Of the 803 respondents (46.2% of survey population), 29.7% had at least one needlestick injury, and 27.7% of this group had two or more. Risk factors included evening shifts, pat-down searches, patrol duties, male gender and less experience. Only 39.2% sought medical attention for these injuries. CONCLUSIONS: Needlestick injuries occur with considerable frequency in this group of law enforcement personnel, suggesting an increased risk of becoming infected with bloodborne pathogens, including hepatitis B, hepatitis C and HIV.     

Implication of the prevalence of needlestick injuries in a general hospital in Malaysia and its risk in clinical practice

Objectives  To determine the prevalence of cases and episodes of needlestick injury among three groups of health care workers in the past one-year, the level of knowledge on blood-borne diseases and universal precautions and the practice of universal precautions. Other factors associated with the occurrence of needlestick injuries and the reporting of needlestick injuries were also analysed. Methods  A cross-sectional study was conducted in May 2003 to study the needlestick injuries among 285 health care workers (doctors, nurses, medical students) in a public teaching hospital in Negeri Sembilan, Malaysia. Results  The prevalence of needlestick injuries among the respondents was 24.6% involving 71 cases i.e. 48.0% among doctors, 22.4% among medical students, and 18.7% among nurses and the difference was statistically significant (p<0.001). There were a total of 174 episodes of needlestick injury. Prevalence of episode of needlestick injuries was highest among doctors (146%), followed by nurses (50.7%) and medical students (29.4%). Cases of needlestick injuries attained lower scores on practice of universal precautions compared to non-cases (p<0.001). About 59% of cases of needlestick injury did not report their injuries. Conclusions  The study showed that needlestick injuries pose a high risk to health care workers and it is underreported most of the time. Many needlestick injuries can be prevented by strictly following the practice of universal precautions.     

Increasing antibiotic resistance among isolates of Escherichia coli recovered from inpatients and outpatients in a Saudi Arabian hospital.

OBJECTIVE: To study the pattern of antibiotic resistance among Escherichia coli and the trend in resistance during a 6-year period in a Saudi Arabian hospital. DESIGN: Retrospective in vitro surveillance study of the antibiotic susceptibility pattern among E. coli isolates recovered from outpatients and from inpatients. SETTING: A general hospital in Saudi Arabia. PATIENTS: All patients with a culture positive for E. coli during a 6-year study period. RESULTS: A statistically significant increase in antibiotic resistance was observed among outpatient and inpatient isolates of E. coli. Inpatient isolates were more likely to be resistant to antimicrobial agents. Among isolates from outpatients, 50% were resistant to ampicillin, 33% were resistant to trimethoprim-sulfamethoxazole (TMP-SMZ), and 14% were resistant to ciprofloxacin. Among isolates from inpatients, 63% were resistant to ampicillin, 44% were resistant to TMP-SMZ, and 33% were resistant to ciprofloxacin. There was a low rate of resistance to imipenem (0.3% of isolates), amikacin (2%), and nitrofurantoin (2.4%-6.5%). Resistance to ceftazidime was detected in 9% of outpatient isolates and 17% of inpatient isolates. Multidrug resistance was defined as resistance to 2 or more classes of antibiotics. Multidrug resistance was detected in 2.0%-28.1% of outpatient isolates and 7.4%-39.6% of inpatient isolates, depending on the combination of antimicrobials tested. More isolates were resistant to ampicillin plus TMP-SMZ than to any other combination of antimicrobials. CONCLUSION: The prevalence of antibiotic resistance among outpatient and inpatient E. coli isolates increased during the study period. The rates of antibiotic resistance were statistically significantly higher among inpatient isolates, compared with outpatient isolates. These findings call for wiser use of antibiotics and continued surveillance of antibiotic resistance.     

Evaluation of quality improvement interventions to reduce inappropriate hospital use.

OBJECTIVE: To assess the impact of process analyses and modifications on inappropriate hospital use. DESIGN: Pre-post comparison of inappropriate hospital use after process modifications. SETTING: The Department of Internal Medicine of the Geneva University Hospitals, Switzerland. PARTICIPANTS: A random sample of 498 patients. INTERVENTIONS: Two processes of care (i.e. non-urgent admissions and transfer to a rehabilitation hospital), which influenced inappropriate hospital use, were identified and modified. The impact of these modifications was then assessed. Main Outcome Measures: The proportion of inappropriate hospital admissions and inappropriate hospital days. RESULTS: As a baseline assessment before quality improvement interventions, the appropriateness of hospital use (admissions and hospital days) was evaluated using the Appropriateness Evaluation Protocol (AEP) in a sample of 500 patients (5665 days). After modification of the two processes through a quality improvement program, inappropriate hospital use was reassessed in a sample of 498 patients (6095 days). Inappropriate hospital admissions decreased from 15 to 9% (P = 0.002) and inappropriate hospital days from 28 to 25% (P = 0.12). CONCLUSION: Using the AEP as a criterion, the quality improvement interventions significantly reduced inappropriate hospital use due to the process of non-urgent admissions, but the reduction of inappropriate hospital days specifically attributed to the transfer to the rehabilitation hospital did not reach statistical significance.

Unintentional needlestick injuries in livestock production: a case series and review

Livestock producers and their employees sometimes experience unintentional needlestick injury (NSI) while vaccinating or injecting medications into animals. There is little published regarding the medical complications that can develop from this occupational exposure. The objectives of this study were to (1) perform a retrospective review of animal-related NSIs treated at a tertiary medical center of a rural state; and (2) review the risks of NSI and measures to decrease their occurrence. Medical records of patients with NSI related to animal injection were identified from the University of Iowa Hospitals and Clinics database from 2002 to 2008 and reviewed. Nine patients received medical care for NSI that occurred while vaccinating farm animals. Most common NSI site was the nondominant hand and most occurred while attempting to inject the animal. Soft tissue infection was common and all nine received oral and/or intravenous antibiotics. Two thirds required hospital admission. Three required surgery and one had a bedside incision and drainage procedure. One patient had a serious inflammatory reaction with necrosis in the leg due to the oil adjuvant in the animal vaccine. Another case had a probable mycetoma with osteomyelitis and soft tissue infection due to the bacteria Streptomyces, which is a NSI complication not previously reported. Although medical complications from farm-related NSIs do not appear to be common, this case series illustrates how these injuries can be debilitating, costly, and lead to loss of work time and productivity. Producers and employees who inject livestock need to be aware of the risks and utilize measures to decrease unintentional NSI.
