Increasing sharp safety device use in healthcare: a semi-structured interview study.

The use of sharp safety devices in healthcare is considered the most important means of preventing occupational percutaneous injuries and has been mandated for use in most hospitals in industrialized countries including in Canada. However, clinical personnel's perceptions on the use of safety devices needs further characterization to improve compliance. This study's objective was to identify healthcare provider perspectives on different aspects of sharp safety device use and on how use could be increased. Using a constant comparison approach, data from semi-structured interviews with 39 nurses, physicians and phlebotomists providing direct patient care, and six nurses acting as the interface between clinical personnel and purchasing departments, were analyzed. Study participants were from three of the six health authorities in British Columbia. The four major categories that emerged from the data were: selection processes; identification and replacement; training; and multi-level barriers and facilitators. Findings highlighted the importance of including personnel regularly using safety devices at each stage of their selection including when they are being considered for replacement with superior devices, as well as the need for appropriate initial and refresher training, and how practices at the hospital, ward and individual level facilitate safety device use.

Choosing a survey sample when data on the population are limited: a method using Global Positioning Systems and aerial and satellite photographs.

BACKGROUND: Various methods have been proposed for sampling when data on the population are limited. However, these methods are often biased. We propose a new method to draw a population sample using Global Positioning Systems and aerial or satellite photographs. RESULTS: We randomly sampled Global Positioning System locations in designated areas. A circle was drawn around each location with radius representing 20 m. Buildings in the circle were identified from satellite photographs; one was randomly chosen. Interviewers selected one household from the building, and interviews were conducted with eligible household members. CONCLUSIONS: Participants had known selection probabilities, allowing proper estimation of parameters of interest and their variances. The approach was made possible by recent technological developments and access to satellite photographs.

Surgeons' and residents' double-gloving practices at 2 teaching hospitals in Ontario.

BACKGROUND: Surgeons and residents are at increased risk of exposure to blood-borne pathogens owing to percutaneous injury (PI) and contamination. One method known to reduce risk is double-gloving (DG) during surgery. METHODS: All surgeons and residents affiliated with the University of Western Ontario (UWO) and McMaster University in 2005 were asked to participate in a Web-based survey. The survey asked respondents their specialty, the number of operations they participated in per week, their age and sex, the proportion of surgeries in which they double-gloved (DG in ≥75% surgeries was considered to be routine), and the average number of PIs they sustained per year and whether or not they reported them to an employee health service. RESULTS: In total, 155 of 331 (47%) eligible surgeons and residents responded; response rates for UWO and McMaster surgeons were 50% and 39%, respectively, and for UWO and McMaster residents, they were 52% and 47%, respectively. A total of 43% of surgeons and residents reported routine DG; 50% from McMaster and 36% from UWO. Using logistic regression to simultaneously adjust for participant characteristics, we confirmed that DG was more frequent at McMaster than at UWO, with an odds ratio of 3.32 (95% confidence interval 1.35-8.17). Surgeons and residents reported an average of 3.3 surgical PIs per year (2.2 among McMaster participants and 4.5 among UWO participants). Of the 77% who reported at least 1 injury/year, 67% stated that they had not reported it to an employee health service. CONCLUSION: Percutaneous injuries occur frequently during surgery, yet routine DG, an effective means of reducing risk, was carried out by less than half of the surgeons and residents participating in this study. This highlights the need for a more concerted and broad-based approach to increase the use of a measure that is effective, inexpensive and easily carried out.

Ongoing use of conventional devices and safety device activation rates in hospitals in Ontario, Canada.

This study assessed voluntary compliance with the use of sharp safety devices in lieu of conventional ones and the activation status of these safety devices: VanishPoint syringes, Terumo Surshield butterflies, and Insyte Autoguard IV catheters. Sharps disposal containers from various wards in three private, not-for profit, university-affiliated Ontario hospitals were audited during 9 days in August 2007. In the 149 audited sharps containers, 55% of all syringes found were conventional compared with 45% that were safety syringes. In the three hospitals, the percentages of conventional (non-safety) vs. safety syringes found in used sharps containers were as follows, respectively: (i) 72% conventional and 28% safety, (ii) 55% conventional and 45% safety, and (iii) 65% conventional and 35% safety. In addition, it was found that 77% of 2131 Terumo butterflies, 97% of 1117 Insyte Autoguard IV catheters, and 87% of 4897 VanishPoint syringes in the containers had been activated. This study, carried out approximately 1 year before it was legally required to use safety instead of sharp conventional devices, found that most devices in use were conventional ones. It was also found that only the activation rate for the safety IV device was acceptable.

Complexity of food preparation and food security status in low-income young women.

PURPOSE: This study was conducted to explore whether preparing more complex meals was associated with higher food security status. METHODS: This mixed-methods, community-based study involved the use of semistructured interviews to examine the cooking practices of a group of young, low-income women in Montreal. Fifty participants aged 18 to 35 were recruited at 10 locations in five low-income neighbourhoods. Food security status was the main outcome measure and the main exposure variable, "complex food preparation," combined the preparation of three specific food types (soups, sauces, and baked goods) using basic ingredients. RESULTS: Low-income women preparing a variety of meals using basic ingredients at least three times a week were more than twice as likely to be food secure as were women preparing more complex meals less frequently. CONCLUSIONS: Women who prepared more complex meals more frequently had higher food security. Whether this means that preparing more complex foods results in greater food security remains unclear, as this was an exploratory study.

Hands-free technique in the operating room: reduction in body fluid exposure and the value of a training video.

OBJECTIVES: This study sought to determine if (1) using a hands-free technique (HFT)--whereby no two surgical team members touch the same sharp item simultaneously--> or = 75% of the time reduced the rate of percutaneous injury, glove tear, and contamination (incidents); and (2) if a video-based intervention increased HFT use to > or = 75%, immediately and over time. METHODS: During three and four periods, in three intervention and three control hospitals, respectively, nurses recorded incidents, percentage of HFT use, and other information in 10,596 surgeries. The video was shown in intervention hospitals between Periods 1 and 2, and in control hospitals between Periods 3 and 4. HFT, considered used when > or = 75% passes were done hands-free, was practiced in 35% of all surgeries. We applied logistic regression to (1) estimate the rate reduction for incidents in surgeries when the HFT was used and not used, while adjusting for potential risk factors, and (2) estimate HFT use of about 75% and 100%, in intervention compared with control hospitals, in Period 2 compared with Period 1, and Period 3 compared with Period 2. RESULTS: A total of 202 incidents (49 injuries, 125 glove tears, and 28 contaminations) were reported. Adjusted for differences in surgical type, length, emergency status, blood loss, time of day, and number of personnel present for > or = 75% of the surgery, the HFT-associated reduction in rate was 35%. An increase in use of HFT of > or = 75% was significantly greater in intervention hospitals, during the first post-intervention period, and was sustained five months later. CONCLUSION: The use of HFT and the HFT video were both found to be effective.

Could the death of a BC or nurse have been prevented by using the hands-free technique?

In 1991, Bernadette Stringer, a long time BC Nurses' Union health and safety representative, learned about the death of a 48 year old Victoria, B.C., OR nurse who had sustained a hepatitis C contaminated needlestick. This incident led to a study evaluating the hands-free technique's ability to decrease the risk of percutaneous injury, glove tear and mucocutaneous contamination during surgery that Ms. Stringer carried out in partial fulfillment of her Ph.D. (granted in 1998, by McGill University's Joint Departments of Epidemiology, Biostatistics and Occupational Health, in the Faculty of Medicine). That study's main findings were published in 2002 in one of the British Medical Journal's publications, Occupational and Environmental Medicine. The following article will discuss aspects of Bev Holmwood's case, review the literature on the hands-free technique, and describe a new study that has again evaluated the hands-free technique's effectiveness.

Perioperative use of the hands-free technique: a semistructured interview study.

OCCUPATIONALLY CONTRACTED bloodborne infections are preventable, but the use of many protective measures remains limited. THERE IS GROWING EVIDENCE that the use of the hands-free technique (HFT) to pass sharp items during surgical procedures is effective in protecting against sharps injury and bloody contamination. RESEARCHERS CONDUCTED in-depth telephone interviews to explore 20 health care providers' knowledge and use of the HFT. MOST OF THE INTERVIEWEES did not regularly use the HFT, and some were resistant to its use.

Parental perception of sleep problems in children of normal intelligence with pervasive developmental disorders: prevalence, severity, and pattern.

OBJECTIVE: This study compares parents' perceptions of the prevalence, severity, and pattern of sleep problems in children of normal intelligence with pervasive developmental disorders (PDDs) with a normative comparison group of children. METHOD: A survey including the Children's Sleep Habits Questionnaire was mailed to a sample of parents of children (age range 5-12 years) with PDDs (diagnosed by the Autism Diagnostic Interview-Revised) obtained by chart review of the past 7 years and to parents of comparison children matched on age, gender, and postal code. RESULTS: The response rate in the PDD group was 82.2% (37/45) and 55.8% (43/77) in the comparison group. By individually matching, 23 pairs were obtained. The prevalence of sleep problems in the PDD group was reported by parents as being significantly higher than in the comparison group (78% and 26%, respectively; p < .002), as was the severity (mean score 48.2 and 39.0, respectively; p < .001). Values for four of eight sleep subscales including sleep onset delay, sleep duration, sleep anxiety, and parasomnias were significantly higher in the PDD group. CONCLUSIONS: Parents report that sleep problems are significantly more prevalent and severe in children of normal intelligence with PDDs compared with normally developing children, and the pattern appears diverse. Sleep problems in children with PDDs require further research and clinical attention.

Conventional and sharp safety devices in 6 hospitals in British Columbia, Canada.

BACKGROUND: Reengineered sharp safety devices have been recommended to reduce occupational percutaneous injury risk in health care facilities. We conducted this study just over 1 year after passage of legislation requiring the use of sharp safety medical devices to assess the frequency of safety and conventional sharp device use and whether safety features were being activated to cover sharp points after safety devices were used and before disposal. METHODS: Approximately equal numbers of sharps disposal containers from various wards in 6 nonprofit adult and pediatric British Columbia hospitals were audited by paired research assistants, wearing protective clothing. RESULTS: In the 699 audited sharps containers, 7% (1,690/25,910) of all devices were conventional devices, specifically 2% (96/4,702) of all phlebotomy devices, 7% (1,240/17,705) of all syringes, and 10% (354/3,503) of all intravenous catheters. In addition, 94% (4,344/4,602) of all safety phlebotomy devices, 95% (2,955/3,119) of all safety intravenous devices, and 80% (13,050/16,420) of all safety syringes had been activated before disposal. CONCLUSION: More than 1 year after legislation was passed mandating the use of sharp safety devices in British Columbia hospitals, the risk from sharps remains excessive because of the ongoing use of conventional sharp devices and nonactivation of safety devices.

Is use of the hands-free technique during surgery, a safe work practice, associated with safety climate?

BACKGROUND: A better safety climate has been linked to better compliance with safety behaviors. This study assessed whether "management support," the most commonly measured safety climate dimension, was associated with greater use of the hands-free technique (HFT), a work practice recommended for use during surgery to prevent exposure to blood and body fluids. METHODS: Questionnaires from operating room nurses participating in a test retest reliability study and in training sessions for an intervention study, from 9 hospitals in 3 Canadian provinces, were analyzed. RESULTS: Response rates in the hospitals varied from 61% to 97%. Four hundred forty-two operating room nurses responded; 16% reported using the HFT approximately 75% or more of the time in surgery, and 39% had received HFT training. Management support and HFT training were each associated with increased HFT use: odds ratio (OR), 6.63; 95% confidence interval (CI): 1.89-23.30 and OR, 6.36; 95% CI: 1.97-20.51, respectively. When training occurred in a context of management support, HFT use was further increased: OR, 9.12; 95% CI: 2.71-30.72. CONCLUSION: Consistent with previous research linking management support for health and safety to uptake of safety practices, management support and HFT training acted synergistically to increase HFT use most of the time in surgery.

Quality of care in for-profit and not-for-profit nursing homes: systematic review and meta-analysis.

OBJECTIVE: To compare quality of care in for-profit and not-for-profit nursing homes. DESIGN: Systematic review and meta-analysis of observational studies and randomised controlled trials investigating quality of care in for-profit versus not-for-profit nursing homes. RESULTS: A comprehensive search yielded 8827 citations, of which 956 were judged appropriate for full text review. Study characteristics and results of 82 articles that met inclusion criteria were summarised, and results for the four most frequently reported quality measures were pooled. Included studies reported results dating from 1965 to 2003. In 40 studies, all statistically significant comparisons (P<0.05) favoured not-for-profit facilities; in three studies, all statistically significant comparisons favoured for-profit facilities, and the remaining studies had less consistent findings. Meta-analyses suggested that not-for-profit facilities delivered higher quality care than did for-profit facilities for two of the four most frequently reported quality measures: more or higher quality staffing (ratio of effect 1.11, 95% confidence interval 1.07 to 1.14, P<0.001) and lower pressure ulcer prevalence (odds ratio 0.91, 95% confidence interval 0.83 to 0.98, P=0.02). Non-significant results favouring not-for-profit homes were found for the two other most frequently used measures: physical restraint use (odds ratio 0.93, 0.82 to 1.05, P=0.25) and fewer deficiencies in governmental regulatory assessments (ratio of effect 0.90, 0.78 to 1.04, P=0.17). CONCLUSIONS: This systematic review and meta-analysis of the evidence suggests that, on average, not-for-profit nursing homes deliver higher quality care than do for-profit nursing homes. Many factors may, however, influence this relation in the case of individual institutions.

Noisiness in operating theatres: nurses' perceptions and potential difficulty communicating.

Elevated operating theatre noise can be hazardous to patient safety and may cause occupational stress. In a nine-hospital study, background noise and average noise were measured, during operations in different subspecialties, and found to be higher than noise levels recommended by the World Health Organization (WHO) for hospital areas in which patient care takes place. In operations in which nurses had also answered a question about hearing 'quiet', 'normal', and 'loud' talking, speech interference levels were estimated and indicated that nurses and other personnel had to substantially raise their voices to be well understood.

Hands-free technique: preventing occupational exposure during surgery.

Occupational exposure to blood borne pathogens has led to HBV, HCV and HIV infections among surgeons, nurses and other operating room (OR) personnel and, to a lesser degree, patients (Ross et al 2000, The incident investigation teams and others 1997). Of seven OR studies in which an observer or circulating nurse recorded exposures, there was a percuataneous injury in 1.7-15% of all surgeries, and a mucocutaneous contamination in 6.2-50% of all surgeries. (Gerberding et al 1990, Panlilio et al 1991, Popejoy & Fry 1991, Quebbeman et al 1991, Tokars et al 1992, Lynch & White 1993, Stringer, Infante-Rivard & Hanley 2002). Surgeons and residents usually sustained the greatest number of percutaneous and other exposures during surgery.
