Injuries among the Double Disaster Cohort of Persons in the WTC Health Registry Exposed to Superstorm SandyBaumet, Krishna 08 August 2017 (has links)
<p> Introduction: In double disaster cohorts responders are exposed to two potentially hazardous situations. Experience with one disaster may affect how responders behave in the second. We evaluate associations of injuries and exposures, with rescue work performed by WTC responders enrolled in the WTCHR who responded 11 years later to Superstorm Sandy. </p><p> Methods: An 84 question Sandy survey was given to 8870 WTCHR enrollees. Outcome measures included total number of injuries, extremity sprains and lacerations and the exposures encountered. A "home danger" variable includes all the reparation and clean- up activities. All analyses were conducted with SAS 9.4. Using multivariable logistic regression, unadjusted and adjusted odds ratios were calculated to estimate association strength between work and volunteer status, age, race, gender, education and 9/11 rescue worker status. </p><p> Results: A total of 4558 (51%) of enrollees participated. 56% were male, 45-64 years of age (62.9%), non-Hispanic white (71.1%) and 44.28% had 2010 income > $75,000. Among 1,044 Sandy responders, 64% of paid workers and 42% of volunteers were also 9/11 workers. Volunteers had increased odds ratios for >1 injury: adjusted odds ratio (aOR) 2.42(95% CI: 1.60-3.64), compared to non-rescue workers. Exposure to Home Danger hazards had an adjusted odds ratio of 7.53 (5.16-10.99) for multiple injuries, suggesting the importance of evacuation and hazard education </p><p> Discussion: Our study shows that volunteers exposed to Sandy have increased odds of having more than one injury and for extremity injury.</p><p>

A critical look at measurement of work outcomes for people with arthritisAlHeresh, Rawan 29 October 2015 (has links)
STUDY ONE
Objective. To evaluate the methodological quality of studies examining psychometric properties of work outcome assessments for people with arthritis to guide instrument selection use based on quality of literature.
Methods. A systematic review was conducted through a structured search to identify articles describing studies of assessment development and studies of their psychometric properties. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist was used to appraise the included studies. Finally, an evidence synthesis was performed to combine findings.
Results. Nine arthritis specific work outcome assessments were identified; 17 articles examining the psychometric properties of these instruments were identified and reviewed. Quality of studies reporting psychometrics of each instrument was highly variable. The evidence synthesis showed that the Work Limitations Questionnaire had the strongest quality evidence of internal consistency and content validity (including structural validity and hypothesis testing), followed by the Work Instability Scale. None of the instruments had strong quality evidence of criterion validity or responsiveness.
Conclusion. Considering the high variability and the low quality of the literature, we recommend that instrument developers integrate studying full psychometric assessment of their instruments, including responsiveness and criterion validity, and consult guidelines (i.e. COSMIN) in reporting their findings.
STUDY TWO
Background. The World Health Organization – Health and Work Performance Questionnaire (HPQ) was developed to ascertain absence from work and reduced work performance in the workplace due to health problems. The purpose of this study is to evaluate the construct validity and scoring methods of the work performance subscale of the HPQ for people with arthritis.
Methods. Cross-sectional data from a randomized clinical trial on preventing work limitations was used. Construct validity of work performance was examined through hypothesis testing using convergence and divergence based on established risk factors from the literature. Pearson’s correlations were used for continuous data, and Spearman’s Ranked correlations for categorical data were used to test the hypotheses. Both scoring methods of the HPQ (absolute and relative) were evaluated.
Results. Data from 287 participants showed that the sample had moderate levels of limitations in work performance. The HPQ showed acceptable construct validity through convergence and divergence. The absolute scoring method had more significant and stronger associations than the relative scoring method.
Conclusion. This study was the first exploring the construct validity of the HPQ for people with arthritis, and since construct validity is a continuing process, more research is needed to further assess the ability of the HPQ to measure work performance. One scoring method (i.e. absolute) was more informative that the other. More research is needed to explore other psychometric properties of the HPQ such as responsiveness and test-retest reliability.

Injuries on Mechanized Logging Operations in the Southeastern United StatesMilburn, Jason S. Jr. 16 July 1998 (has links)
A random sample of injuries to employees of mechanized logging operations in the piedmont and coastal plain regions of the Southeastern U.S. was taken from the 1996-1997 claims records of three cooperating Worker's Compensation Insurance carriers. For each claim, information was gathered about the accident. Additional information on equipment, labor, and operations was gathered for each firm reporting a sample claim. All data was recorded in a spreadsheet program for sorting and analysis.
The deckhand was the crew member most frequently injured (34% of claims), followed by equipment operators (28%) and truck drivers (24%). The delimbing/topping job function resulted in 24% of injuries, followed by maintenance/repair of equipment (19%), operating equipment (15%), and mounting/dismounting equipment (9%). The injuries occurred on the log deck (41%), in the woods (29%), and at a shop (11%). Most injuries were "struck by" type (50%), but 21% were "falls". The mean claims cost was $10,920 and the median claims cost was $1,200. On fully mechanized operations, 24% of total injuries are still a result of chainsaw delimbing or felling. Equipment operator injuries occur during maintenance/repair (29%) and while mounting/dismounting the equipment (23%). One-third of injuries to truck drivers was the result of motor vehicle accidents.
Conclusions:
* A worker performing equipment maintenance or repair, or a worker felling or delimbing a tree not processed by a feller-buncher or delimbing device, has the greatest risk of injury on fully-mechanized operations.
* Mechanization of the delimbing function will reduce but not eliminate the most costly injuries, where a worker on the ground is "struck-by" a tree, limb, or log.
* Equipment maintenance or repair should be performed in the controlled environment of a shop, rather than in the field, in order to decrease injuries.
* Operating a chainsaw is still a very dangerous logging job function, even on mechanized operations. All employees that use a chainsaw should undergo extensive training, and only trained employees should use a chainsaw. / Master of Science

An occupational epidemiology study on the acute irritant effects due to exposure to borax particulateHu, Xiaohan 01 January 1991 (has links)
Acute irritant symptoms can be caused by a variety of airborne environmental agents. Earlier studies on the acute irritant effects by comparison of symptom events at the beginning and end of the work shift or between groups at different exposure levels have been inadequate. This research examines the acute irritant effects of occupational exposure to sodium borate dusts (borax) using the repeated measurement design. The study population was composed of 79 exposed and 29 unexposed employees. The subjects were queried about irritant symptoms at hourly intervals for the first six hours of the shift and four days in a row. They were also provided a means to record the timing of the symptom by pressing an event marker. Acute pulmonary function change measured by peak expiratory flow rate (PEFR) was obtained. Dose-response relationships were examined by computing incidence rates of specific symptoms at increasing exposure levels. Both ordinary and two-stage logistic regression analysis were used in symptom analysis. L-th autoregressive models were applied in the assessment of acute change in PEFR in relation to exposure concentrations. The major findings showed that dose-response relationships were present for each of five acute irritant symptoms. Increased symptom responses were associated with measured exposure across entire exposure range; no clear threshold was indicated. On the other hand, analysis of acute change in PEFR revealed that only a temporary drop of PEFR was associated with an exposure level above 2 mg/m$\sp3$. Although this change in PEFR was of no clinical importance, it provided an objective measurement that was consistent with findings for acute symptoms. The event marker was found to be useful in allowing more precise estimation of the time of symptoms in relation to prior short-term peak exposures. It showed that the symptom response to exposure peaks was very quick, if not nearly instantaneous. It also provided validation that the recalled symptom onset time was satisfactory. However, inconsistent marker use with respect to symptom and marker use recall were not infrequent, suggesting that this event marker may not replace the traditional interview in obtaining subjective symptom events in future epidemiologic studies.

Farm safety and health needs among limited resource farmersin selected counties of North CarolinaIbrahim, Mohammed J. 11 October 1999 (has links)
The literature illustrates that agriculture continues to be the leader in the nation for accidents. The attitudes and behaviors of farmers and farm workers towards farm equipment and its safe use are major concerns. Farm safety education and research are strongly needed to prevent or reduce farm injuries. The primary purpose of this study was to investigate health and safety problems among limited resource farmers in selected counties of North Carolina. The survey method with a mail questionnaire was used to collect the data. The sample for this study consisted of 297 limited resource farmers in North Carolina.
Selected conclusions drawn from the findings were:
1. The risks associated with limited resource farmers and their workers, such as use of tractors, machinery, and farm chemicals are very high.
2. Farmers between the ages of 36-50 have higher expected injuries compared to other age groups.
3. Training associated with the use of farm tractors, machinery, and personal protective equipment (PPE) is very essential for limited resource farmers.
4. The research suggested that hazards exposed by using tractors without rollover protection structure (ROPS) could result in higher injuries among limited resource farmers and workers.
Selected recommendations:
1. Federal and state governments should give incentives to farmers to encourage them to retrofit ROPS on their old tractors.
2. Mandatory training should be required for small scale or limited resource farmers on utilization of farm equipment operation and personal protective equipment (PPE) utilization.
3. New design of preventive guards and shields that can be easily removed or opened for maintenance and remounted or closed afterward are needed. / Ph. D.
