Objectives.To evaluate the incidence of needlestick injuries (NSIs) among different models of safety-engineered devices (SEDs) (automatic, semiautomatic, and manually activated safety) in healthcare settings.Design.This multicenter survey, conducted from January 2005 through December 2006, examined all prospectively documented SED-related NSIs reported by healthcare workers to their occupational medicine departments. Participating hospitals were asked retrospectively to report the types, brands, and number of SEDs purchased, in order to estimate SED-specific rates of NSI.Setting.Sixty-one hospitals in France.Results.More than 22 million SEDs were purchased during the study period, and a total of 453 SED-related NSIs were documented. The mean overall frequency of NSIs was 2.05 injuries per 100,000 SEDs purchased. Device-specific NSI rates were compared using Poisson approximation. The 95% confidence interval was used to define statistical significance. Passive (fully automatic) devices were associated with the lowest NSI incidence rate. Among active devices, those with a semiautomatic safety feature were significantly more effective than those with a manually activated toppling shield, which in turn were significantly more effective than those with a manually activated sliding shield (P < .001, x2 test). The same gradient of SED efficacy was observed when the type of healthcare procedure was taken into account.Conclusions.Passive SEDs are most effective for NSI prevention. Further studies are needed to determine whether their higher cost may be offset by savings related to fewer NSIs and to a reduced need for user training.

AbstractObjective:To determine the impact of three needleless intravenous systems on needlestick injury rates.Design:Randomized controlled trial.Setting:1,000-bed tertiary-care Midwestern hospital.Participants:Nursing personnel from general medical, general surgical, and intensive-care units.Interventions:From June 1992 through March 1994, a metal blunt cannula (MBC), two-way valve (2-way), and plastic blunt cannula (PBC) were introduced into three study areas, and needlestick injury rates were compared to three control areas using traditional needled devices.Results:24 and 29 needlestick injuries were reported in study and control areas. Intravenous-therapy-related injuries comprised 45.8% and 57.1% of injuries in each area. Thirty-seven percent and 20.7% of study and control area needlestick injuries were considered to pose a high risk of bloodborne infection. The 2-way group had similar rates of total and intravenous-related needlestick injuries compared to control groups. The PBC group had lower rates of total and intravenous-related needlestick injuries per 1,000 patient-days (rate ratios [RR], 0.32 and 0.24; 95°% confidence intervals [CI95], 0.12-0.81 and 0.09-0.61;P=.02 andP=.003, respectively) and per 1,000 productive hours worked (RR, 0.11 and 0.08; CI95, 0.01-0.92 and 0.010.69;P=.03 andP=.005, respectively) compared to controls.Conclusions:Needlestick injuries continued in study areas despite the introduction of needleless devices, and risks of bloodborne pathogen transmission were similar to control areas. The PBC device group noted lower rates of needlestick injuries compared to controls, but there were problems with product acceptance, correct product use, and continued traditional device use in study areas. Low needlestick injury rates make interpretations difficult. Further studies of safety devices are needed and should attempt greater control of worker behavior to aid interpretation.

AbstractObjectives:To assess the rate of needlestick injury in hospital personnel in an Italian region. To identify risk factors potentially amenable to correction.Design:Hospital workers undergoing hepatitis B prevaccination testing in 1985 through 1986 were interviewed regarding needlestick injury in the previous year, job category, area of work, years of employment, and other pertinent information.Setting:Of the 98 public hospitals of the Latium region, 68 participated in the survey: 32 of 55 with less than 200 beds, 20 of 25 with 200 to 300 beds, 11 of 13 with 400 to 900 beds, and all of the 5 with more than 1,000 beds.Participants:All healthcare workers providing direct patient care or environmental services as well as student nurses were invited by the hospital directors to undergo hepatitis B prevaccination testing and vaccination, if eligible.Results:Of 30,226 hospital workers of the 68 participating hospitals, 20,055 were interviewed (66.3%): 47.7% of the 7,172 doctors, 71% of the 14,157 nurses, 55.9% of the 2,513 technicians, and 71.9% of the 6,384 ancillary workers. Needlestick injury was recalled by 29.3%; the rates were 54.9%, 35.3%, 33.8%, 26.5%, 18.7%, and 14.7% in surgeons, registered and unskilled nurses, physicians, ancillary workers, and technicians, respectively. The recalled injury rate was 39.7% and 34.0% in surgical and intensive care areas; in infectious diseases, it was 16.7%. Bates were lower in hospitals with 200 to 300 beds (25.6%). The needlestick injury rate declined from 32% in those with less than 5 years of employment to 28% in those with more than 20 years (p<.01). Prevalence of HBV infection was higher in student nurses and young workers recalling a needlestick exposure (14.3% and 15.8%, respectively), versus 10.1% and 12.8% in those not exposed (p<.01 and <.05, respectively).Conclusions:Parenteral exposure to bloodborne infectious agents is a relevant risk among healthcare workers in our region, particularly in defined job categories and hospital areas (surgeons, nurses, surgical, and intensive care areas). Immunization and educational efforts should be made along with better designs of devices to reduce the risk of infection.

Hoeffding Inequality

Algorithms that compare two proteins or DNA sequences and produce an alignment of the best matching segments are widely used in molecular biology. These algorithms produce scores that when comparing random sequences of length n grow proportional to n or to log (n) depending on the algorithm parameters. The Azuma-Hoeffding inequality gives an upper bound on the probability of large deviations of the score from its mean in the linear case. Poisson approximation can be applied in the logarithmic case.

Random Restriction

Optical mapping is a new technique to generate restriction maps of DNA easily and quickly. DNA restriction maps can be aligned by comparing corresponding restriction fragment lengths. To relate, organize, and analyse these maps it is necessary to rapidly compare maps. The issue of the statistical significance of approximately matching maps then becomes central, as in BLAST with sequence scoring. In this paper, we study the approximation to the distribution of counts of matched regions of specified length when comparing two DNA restriction maps. Distributional results are given to enable us to compute p-values and hence to determine whether or not the two restriction maps are related. The key tool used is the Chen-Stein method of Poisson approximation. Certain open problems are described.

Needlestick injury in healthcare settings is a global issue. Despite being recognized for many years, needlestick and sharps injuries (NSIs) continue to present a risk of occupational exposure to blood-borne pathogens for health care works (HCWs). The objectives of the study were to determine the prevalence of needlestick injuries among HCWs in Rizgary Teaching Hospital and to identify the causes of needlestick injuries. A cross-sectional study was conducted on 76 healthcare workers in Rizgary Teaching hospital; there were a total of 45 males, 31 females. The data collections were administrated using face-to-face interviews to ensure a good response rate and to ensure all questions were answered. Most (52.6%) needlestick injuries occurred in wards with syringe needles being the most common causative tool; surgery ward was the most prevalent site of needlestick injuries occurrence (42.1%). The percentage of acupuncture was high and needles were the most common cause, and most injuries occurred during the re-use of the needles. The study recommends several measures to prevent and reduce acute injuries among HCWs; these measures include health education, behavior change, safer devices, and an educational program to educate these HCWs.

To the Editor: I have just discovered an error in “Traumatic Injuries Among Medical Center Employees” (AAOHN journal 36(8):318–325, 1988), which I would like to bring to the attention of the readers of AAOHN journal. In the Discussion section on page 320 there is mention of a reduction in the reported needlestick injury rate for registered nurses, licensed practical nurses, and custodians. The needlestick injury rate mentioned for the earlier study (1979–1981) is incorrectly reported. The old rate should be 11.4 per 100 FTE for custodians, not 113.5. Similarly the old rates should be 12.4 per 100 FTE for registered nurses and 5.7 per 100 FTE for licensed practical nurses. We inadvertently misreported our earlier results by a factor of 10. With the above corrections made, the reported needlestick injury rates increased from 11.4 to 11.6 per 100 FTE (1.8%) for custodians, from 12.4 to 32.7 per 100 FTE (163.7%) for registered nurses, and from 5.7 to 26.5 per 100 FTE (364.9%) for licensed practical nurses. Whether this represents an increase in actual incidents among nurses or a decrease in underreporting of incidents among nurses can not be determined at this time. With all of the efforts being made to control needlestick injuries, one would assume that this is a reporting phenomenon. It does bear further watching, however. We regret the above error. John S.

Objectives: The objective of this study was to evaluate the impact rest time between games may have on injury rates as it pertains to overall incidence, injury location and player position. Methods: For this descriptive epidemiological study, data was obtained from official NFL gamebooks. In-game injuries were queried for all regular season games from all 32 teams over the course of four seasons (2013 to 2016). Only injuries which resulted in a stoppage of time during gameplay were included. Player position and injured body part were taken from the following week’s injury report. Rest periods between games were classified as short (4 days), regular (6-8 days), or long (10+ days) rest. Positions were categorized into Quarterback, Skill (wide receiver, running back and defensive backs), Lineman, and Other (fullback, linebacker and tightend). Overall observed injury rates, as well as injury rates specific to anatomic location and player position, were analyzed in correlation to different rest periods. Statistical significance was determined using the ANOVAprocedure of observed mean injuries per game. Pairwise analysis, through 2 sample T-test, was conducted to assess statistical significance between short, regular and long rest. Results: A total of 2,846 injuries were identified throughout the four seasons. ANOVA testing of all 3 cohorts taken together demonstrated a statistically significant difference between injuries/game between short, regular, and long rest (p = 0.012). With short rest, a mean of 1.26 injuries/game were observed (95% CI 1.046, 1.470), which was statistically significantly different when compared to the 1.53 observed injuries/game with regular rest (95% CI 1.463, 1.601; p = 0.029). Games with short rest were not found to be significantly different when compared to the 1.34 observed injuries/game associated with long rest (95% CI 1.186, 1.486; p = 0.555). Regarding player positions, only the Other cohort achieved statistically significantly less observed injuries/game with games played on Thursday compared to regular (p=0.0002) and long (p = 0.026). The quarterback position was the only position which sustained more injuries than expected with games played on Thursday compared to both regular and long rest; however, these results did not reach statistical significance (p = 0.09). No statistical difference was found regarding injury location in correlation to differences in rest periods. Conclusion: Our data suggests that there is a significant association between the amount of rest between games and observed injuries in the NFL. Interestingly, Thursday night games were found to have fewer injuries per game when compared to games played on regular rest. Subgroup analysis revealed fewer observed injuries with short rest for linebackers, fullbacks, and tightends. Although quarterbacks were observed to have more injuries than expected on short rest, this did not reach statistical significance. The results of this study do not support that less rest associated with Thursday night games leads to higher injury rates; however, quarterback injury rates may potentially be impacted with shortened rest.
