Objective: To combine human factors engineering techniques with qualitative observation of nurses in practice to analyze the nature of nurses' cognitive work and how environmental factors create disruptions that pose risks for medical errors. Background: Few researchers have examined the nature of nurses' cognitive work while in practice with patients. Researchers have described the broad range of thinking processes required in the acute care work setting, but have failed to examine how such processes are conducted and influenced by the complex care environment. A combined research methodology enables researchers to better understand how the nursing process becomes disrupted and the potential influence of this disruption on the safe and effective care of patients. Methods: An ethnographic study, using mixedmethodological approaches, involved 7 staff registered nurses. The quantitative and qualitative data collection included field observation and summarative interviews. Findings: A high number of cognitive shifts and interruptions, and a nurse's cumulative cognitive load, create the potential for disrupting a nurse's attention focus during care of patients. A majority of interruptions occurred as nurses performed interventions, particularly medication preparation. Conclusion: New attention must be given to how care systems and work processes complement or interfere with nurses' cognitive work.
Implementation of patient lifts can be effective in reducing occupational musculoskeletal injuries to nursing personnel in both LTC and acute care settings. Strategies to facilitate greater use of mechanical lifting devices should be explored, as further reductions in injuries may be possible with increased use.
Objective This study compared the impact of cognitive-behavioral therapy for pain (CBT-P), mindful awareness and acceptance treatment (M), and arthritis education (E) on day-to-day pain- and stress-related changes in cognitions, symptoms, and affect among adults with rheumatoid arthritis (RA). Method 143 RA patients were randomized to one of the three treatment conditions. CBT-P targeted pain coping skills; M targeted awareness and acceptance of current experience to enhance coping with a range of aversive experiences; and E provided information regarding RA pain and its management. At pre- and post-treatment, participants completed 30 consecutive evening diaries assessing that day's pain, fatigue, pain-related catastrophizing and perceived control, morning disability, and serene and anxious affects. Results Multilevel models compared groups in the magnitude of within-person change in daily pain- and stress-reactivity from pre- to post-treatment. M yielded greater reductions than did CBT-P and E in daily pain-related catastrophizing, morning disability, and fatigue, and greater reductions in daily stress-related anxious affect. CBT-P yielded less pronounced declines in daily pain-related perceived control than did M and E. Conclusions For individuals with RA, M produces the broadest improvements in daily pain- and stress-reactivity relative to CBT-P and E. These findings also highlight the utility of a diary-based approach to evaluating the treatment-related changes in responses to daily life.
In 2007, the Bureau of Labor Statistics reported that the incidence rate of lost workday injuries from slips, trips and falls (STFs) on the same level in hospitals was 35.2 per 10,000 full-time equivalents (FTE), which was 75% greater than the average rate for all other private industries combined (20.2 per 10,000 FTEs). The objectives of this 10-year (1996-2005) longitudinal study were to: 1) describe occupational STF injury events in hospitals; 2) evaluate the effectiveness of a comprehensive programme for reducing STF incidents among hospital employees. The comprehensive prevention programme included analysis of injury records to identify common causes of STFs, on-site hazard assessments, changes to housekeeping procedures and products, introduction of STF preventive products and procedures, general awareness campaigns, programmes for external ice and snow removal, flooring changes and slip-resistant footwear for certain employee subgroups. The hospitals' total STF workers' compensation claims rate declined by 58% from the pre-intervention (1996-1999) rate of 1.66 claims per 100 FTE to the post-intervention (2003-2005) time period rate of 0.76 claims per 100 FTE (adjusted rate ratio = 0.42, 95% CI: 0.33-0.54). STFs due to liquid contamination (water, fluid, slippery, greasy and slick spots) were the most common cause (24%) of STF claims for the entire study period 1996-2005. Food services, transport/emergency medical service and housekeeping staff were at highest risk of a STF claim in the hospital environment. Nursing and office administrative staff generated the largest numbers of STF claims. STF injury events in hospitals have a myriad of causes and the work conditions in hospitals are diverse. This research provides evidence that implementation of a broad-scale prevention programme can significantly reduce STF injury claims.
Objective: To evaluate the effectiveness of mechanical patient lifts in reducing musculoskeletal symptoms, injuries, lost workday injuries, and workers' compensation costs in workers at a community hospital. Design: Pre-post intervention study. Setting: Three nursing units of a small community hospital. Patients or subjects: Nursing personnel. Interventions: Mechanical patient lifts were made available and nursing staff trained in their use between August 2000 and January 2001. Main outcome measures: Workers completed symptom surveys at baseline and six months after lift training. Pre-intervention and post-intervention rates of injuries and lost workday injuries using Occupational Safety and Health Administration logs of the three study units, from the period July 1999 through March 2003 were analyzed. Injuries potentially related to lifting patients were included in the analyses. Using workers' compensation data from the same time period, the compensation paid ($ per full time equivalent [FTE]) due to injuries during the pre-intervention and post-intervention period was calculated. Results: Sixty one staff members were surveyed pre-intervention; 36 (59%) completed follow up surveys. Statistically significant improvements in musculoskeletal comfort (p,0.05) were reported for all body parts, including shoulders, lower back, and knees. Injury rates decreased post-intervention, with a relative risk (RR) of 0.37 (95% confidence interval (CI) 0.16 to 0.88); decreased injury rates persisted after adjustment for temporal trends in injury rates on non-intervention units of the study hospital (RR = 0.50, 95% CI 0.20 to 1.26). Adjusted lost day injury rates also decreased (RR = 0.35, 95% CI 0.10 to 1.16). Annual workers' compensation costs averaged $484 per FTE pre-intervention and $151 per FTE postintervention. Conclusion: Reductions were observed in injury rates, lost workday injury rates, workers' compensation costs, and musculoskeletal symptoms after deployment of mechanical patient lifts. Strengths of this study include the community hospital setting and the inclusion of a variety of different outcomes. Limitations include the pre-post study design and the small sample size.
