Relationships between task awareness, comprehension strategies, and literacy outcomes.

Reading is typically guided by a task or goal (e.g., studying for a test, writing a paper). A reader's task awareness arises from their mental representation of the task and plays an important role in guiding reading processes, ultimately influencing comprehension outcomes and task success. As such, a better understanding of how task awareness arises and how it affects comprehension is needed. The present study tested the Task Awareness Mediation Hypothesis. This hypothesis assumes that the strategies that support reading comprehension (e.g., paraphrasing, bridging, and elaborative strategies) also support a reader's task awareness while engaged in a literacy task. Further, it assumes that the reader's level of task awareness partially mediates the relationship between these comprehension strategies and a comprehension outcome. At two different time points in a semester, college students completed an assessment of their propensity to engage in comprehension strategies and a complex academic literacy task that provided a measure of comprehension outcomes and an assessment of task awareness. Indirect effects analyses provided evidence for the Task Awareness Mediation Hypothesis showing that the propensity to engage in paraphrasing and elaboration was positively predictive of task awareness, and that task awareness mediated the relationships between these comprehension strategies and performance on the complex academic literacy task. These results indicate that task awareness has complex relationships with comprehension strategies and performance on academic literacy tasks and warrants further consideration as a possible malleable factor to improve student success.

Assessment of Prehospital Monitor/Defibrillators for Clostridioides difficile Contamination.

OBJECTIVES: The purpose of this study was to determine if Clostridioides difficile (C. diff) was present on the electrocardiogram (ECG) right arm leads, blood pressure cuffs, and fingertip pulse oximetry sensors of monitor/defibrillators used in the prehospital setting. METHODS: On March 22, 2019, a total of 20 prehospital monitor/defibrillators located at an Emergency Medical Service (EMS) station in Alabama (USA) were assessed for C. diff. The inside area of the fingertip pulse oximetry sensor, patient contact side of the blood pressure cuff, and right arm ECG lead of monitor/defibrillators (n = 60) were swabbed using a sterile cotton-tipped applicator saturated in a 0.85% Sodium Chloride solution. These cotton-tipped applicators were then inserted, scored, and released into Banana Broth vials. The vials were then sealed tightly and immediately transported to the laboratory, where they were incubated at 36°C for 72 hours. Colorimetric change from red to yellow was considered a positive indication for the presence of C. diff. RESULTS: Of 20 blood pressure cuffs, 15 had C. diff contamination (75%); C. diff was also present on 19 of 20 fingertip pulse oximeter sensors (95%) and 20 of 20 ECG right arm monitor leads (100%). CONCLUSION: Prehospital monitor/defibrillators may represent a significant reservoir of C. diff and other pathogenic bacteria. Improved disinfection protocols for reusable monitoring equipment and transition to disposable monitoring equipment used in the prehospital setting may reduce the risk of patient and EMS provider infection.

Emergency Medical Services resource capacity and competency amid COVID-19 in the United States: preliminary findings from a national survey.

OBJECTIVE: This study aimed to investigate available resources, Personal Protective Equipment (PPE) availability, sanitation practices, institutional policies, and opinions among EMS professionals in the United States amid the COVID-19 pandemic using a self-report survey questionnaire. METHODS: An online 42-question multiple choice survey was randomly distributed between April 1, 2020, and April 16, 2020 to various active Emergency Medical Services (EMS) paid personnel in all 50 U.S. states including the District of Columbia (n = 192). We approximate a 95% confidence interval (±0.07). RESULTS: An overwhelming number of EMS providers report having limited access to N95 respirators, receiving little or no benefits from COVID-19 related work, and report no institutional policy on social distancing practices despite CDC recommendations. For providers who do have access to N95 respirators, 31% report having to use the same mask for 1 week or longer. Approximately ⅓ of the surveyed participants were unsure of when a COVID-19 patient is infectious. The data suggests regular decontamination of EMS equipment after each patient contact is not a regular practice. DISCUSSION: Current practices to educate EMS providers on appropriate response to the novel coronavirus may not be sufficient, and future patients may benefit from a nationally established COVID-19 EMS response protocol. Further investigation on whether current EMS practices are contributing to the spread of infection is warranted. The data reveals concerning deficits in COVID-19 related education and administrative protocols which pose as a serious public health concern that should be urgently addressed.

Emergency medical services oxygen equipment: a fomite for transmission of MRSA?

OBJECTIVES: The primary purpose of this study was to determine if methicillin-resistant Staphylococcus aureus (MRSA) was present on the surface of oxygen cylinders and regulators used in the prehospital setting and secondarily to assess other surfaces for MRSA within the ambulance compartment, as a comparison. METHODS: On 17 March 2018, the surface of oxygen cylinders and regulators located in ambulances at an emergency medical services (EMS) station in North Alabama (n=9) and at an offsite oxygen cylinder storage area (n=70) were swabbed using sterile cotton-tipped applicators saturated in an 0.9% NaCl solution. These cotton-tipped applicators were then streaked across the surface of HardyCHROM MRSA plates, followed by incubation at 36°C for 24 hours. The growth of pink or magenta colonies was considered a positive indication for the presence of MRSA. The motivation for assessing oxygen cylinders at the offsite storage area was to outline the persistence of MRSA on stored oxygen cylinders. RESULTS: Of nine oxygen cylinders tested in the ambulances, nine had MRSA colonisation (100%). MRSA was also present on 67 of 70 oxygen cylinders (96%) tested at the offsite oxygen cylinder storage area. CONCLUSION: Oxygen cylinders appear to act as a fomite for MRSA. The development of universal disinfection protocols for oxygen equipment could help reduce the risk of patient infection due to cross-contamination.
