Comparison of management and workers' perception, attitudes and beliefs toward health and safety in the Ontario manufacturing sector.

INTRODUCTION: The Ontario manufacturing sector is over-represented when it comes to workers' compensation claims in the province. A previous study suggested that this may be the result of compliance gaps with respect to the province's occupational health and safety (OHS) legislation. These gaps may be, in part, due to differences in perceptions, attitudes, and beliefs toward OHS between workers and management. This is noteworthy as these two cohorts, when working well together, can foster a healthy and safe work environment. Therefore, this study sought to ascertain the perceptions, attitudes, and beliefs of workers and management with respect to OHS in the Ontario manufacturing sector and to identify differences between the groups, if any. METHODS: A survey was created and disseminated online to get the widest reach across the province as possible. Descriptive statistics were used to present the data and chi-square analyses were performed to determine if there were any statistically significant differences in responses between workers and managers. RESULTS: In total, 3,963 surveys were included in the analysis, which consisted of 2,401 (60.6%) workers and 1,562 (39.4%) managers. Overall, workers were more likely to state that their workplace was 'a bit unsafe' relative to managers and this difference was statistically significant. There were also statistically significant differences between the two cohorts with respect to health and safety communication matters, the perception of safety as a high priority, whether people work safely when unsupervised, and whether control measures are adequate. CONCLUSIONS: In summary, there were differences in perception, attitudes, and beliefs toward OHS between workers and managers in Ontario manufacturing and these differences must be addressed in order to improve the sector's health and safety performance. PRACTICAL APPLICATIONS: Manufacturing workplaces can improve their health and safety performance by strengthening labor-management relationships, including having routine health and safety communication.

Noise exposure assessment of occupational health and safety (OHS) consultants: A preliminary study.

No published noise exposure assessment of occupational health and safety (OHS) consultants exists. An assessment was performed to quantify the noise level of OHS consultants while they were on site at a client's facility. OHS consultants wore a dosimeter set to A-weighting, slow response, 60 s log interval and a criterion level of 85dBA with a 3 dB exchange rate. Both the projected time-weighted average (TWA) and projected dose were recorded. Of the 32 noise assessments collected, three had projected TWAs that exceeded the occupational exposure limit of 85 dBA. Nearly 75% of the projected TWA measurements were equal or greater than the Action Level of 80 dBA. According to best practices, occupational noise levels greater than 80 dBA present a risk for noise-induced hearing loss and, therefore, a hearing loss prevention program should be implemented.

Comparing subjective and objective response to medications in Parkinson's disease patients using the Personal KinetiGraph™.

BACKGROUND: Management of motor symptoms in Parkinson's Disease(PD) relies on subjective information provided by patients, the quality of which can be affected by many factors. RATIONALE: Objective data collected during daily life could complement this information and improve management of motor symptoms. OBJECTIVES: To assess the usefulness of the Personal KinetiGraph (PKG) in characterizing the intensity and timing of motor symptoms in PD patients. METHODS: Retrospective study of all PD patients followed at a tertiary academic movement disorders center assessed by PKG between December 1, 2016 and October 30, 2018. PKG was worn for 7 days prior to the clinical visit. We compared the information obtained from the interview and the clinical visit, and assessed the impact of the PKG on treatment decision making. RESULTS: 170 PKG results were reviewed. PKG complemented patient input in 82.9%(141/170) and led to medication changes in 71%(100/141) of the complemented inputs. PKG contributed the least to correcting or complementing patients' input when patients self-reported as undertreated (22%) and the most when patient were unable to answer all questions regarding motor response to individual doses (100%) (Fisher, p < 0.0001). The majority of patient undergoing 3 or 4 PKG encounters did not reach a controlled state as defined by PKG until the 3rd or 4th encounter, suggesting that repeated use of the PKG might be needed to help optimize motor control as therapy changes done after one encounter might not be enough. CONCLUSIONS: PKG might be useful in supplementing patient-provided information for accurate assessment and treatment plan.

Drug induced parkinsonism: Symptomatic beyond 22 months.

We report 2 cases of drug induced Parkinsonism followed longitudinally that remained symptomatic 22 and 27 months after stopping causative agents with normal dopamine ioflupane iodine-123 (DaT) single-photon emission computed tomography (SPECT) scans at 8 and 16 months.

Variability and Delay in Telestroke Physician Alert among Spokes in a Telestroke Network: A Need for Metric Benchmarks.

INTRODUCTION: Telestroke has increased access to acute management of ischemic stroke in areas that lack stroke care expertise, yet delays persist in evaluation and treatment. We describe variation in time to alert a telestroke physician of suspected acute ischemic stroke patients potentially eligible for acute stroke therapies among community hospitals in our telestroke network, and explore demographic and spoke-related characteristics associated with delays. METHODS: From our telestroke registry, we identified suspected acute ischemic stroke patients who arrived within 6 hours of symptom onset and underwent video consultation at 1 of 17 community hospitals in our hub-and-spoke network. We compared time between patient arrival to telestroke alert (door-to-page-time) and to tissue plasminogen activator (tPA) administration for eligible patients (door-to-needle-time). We identified factors associated with prolonged metrics. RESULTS: Of 1020 cases between 9/2015 and 3/2017, 47% received tPA. Sixty percent had door-to-page-time more than 15 minutes (median 19.5; IQR, 11-34). Door-to-page-time more than 15 minutes was associated with an 8-fold increase in likelihood of door-to-needle-time more than 60 minutes. Patients with severe stroke experienced faster door-to-page-times. Hospitals with more beds had prolonged door-to-page-time. Full time in-house neurology presence, even when not covering emergent consultations, was associated with faster door-to-page-time over telestroke. Seventy-one percent of patients underwent CT brain prior to the telestroke physician alert; this scenario delayed door-to-page and door-to-needle times. CONCLUSIONS: Door-to-page-time varied considerably among spokes. Awaiting CT scan prior to alerting the telestroke consultant of a stroke code delayed metrics. Telestroke physician alert standards are needed, as are educational initiatives on acute ischemic stroke management and workflow.

Association Between Splenic Contraction and the Systemic Inflammatory Response After Acute Ischemic Stroke Varies with Age and Race.

Animal models have demonstrated the deleterious contribution of splenic immunocytes on secondary brain injury after stroke. While previous work has demonstrated splenic contraction (SC) in patients with acute ischemic stroke (AIS) and intracranial hemorrhage (ICH), no clinical studies have examined the relationship between the systemic inflammatory response syndrome (SIRS) with SC in stroke patients. This is a retrospective analysis of a previous prospective observational study where daily spleen sizes were evaluated in 178 acute stroke patients. Spleen contraction was based on previously established normograms of healthy volunteers from the same study. SC from the first 24 h of stroke onset was evaluated against criteria for SIRS for the first 5 days of admission after AIS. Ninety-one patients had verified AIS without concurrent infection at admission. SIRS was not associated with SC at admission. African-American patients with early SIRS had higher odds of having SC. Older patients with persistent SIRS at 72 h had lower odds of SC. At 48 h, there was significantly higher lymphocytosis and lower neutrophils present in patients with SC. Patients with SIRS at 72 h were more likely to have worse discharge mRS. This study provides evidence for an association among SC and SIRS in African-American patients suggesting that spleen changes could be a biomarker for detecting SIRS in this population. Our data also indicate a counter association between SC and a lack of SIRS in patients older than 75. Further studies are needed to ascertain how age affects this association.
