Emergency Medical Services Personnel Compliance with Escalating Airway Algorithm Protocol.

Introduction. When emergency medical services (EMS) personnel respond to emergencies, the decisions they make often can mean life or death for the patient. This is especially true in the case of advanced airway management. Protocols are set in place to ensure that the least invasive airway management techniques are used initially before more invasive techniques. The purpose of this study was to determine how often EMS personnel followed this protocol, while adequately achieving the goals of appropriate oxygenation and ventilation. Methods. This retrospective chart review was approved by the Institutional Review Board of the University of Kansas Medical Center. The authors reviewed the Wichita/Sedgewick County EMS system for cases during 2017 in which patients required airway support. We examined de-identified data to determine if invasive methods were applied in sequence. Cohen's kappa coefficient (κ) and immersioncrystallization approach were used to analyze the data. Results. A total of 279 cases were identified in which EMS personnel used advanced airway management techniques. In 90% (n = 251) of cases, less invasive techniques were not used prior to more invasive techniques and in 80% (n = 222) of cases, the more invasive technique was used alone. A dirty airway was the most common reason for the EMS personnel's choice of using more invasive approaches in achieving the goals of appropriate oxygenation and ventilation. Conclusions. Our data showed that EMS personnel in Sedgwick County/Wichita, Kansas often deviated from the advanced airway management protocols when caring for patients in need of respiratory intervention. Dirty airway was the main reason for using a more invasive approach in achieving the goals of appropriate oxygenation and ventilation. It is important to understand reasons why deviations in protocol were occurring to ensure that current protocols, documentation, and training practices are effective in producing the best possible patient outcomes.

Prehospital Clinical Decision-Making for Medication Administration for Behavioral Emergencies.

Introduction. Prehospital behavioral emergency protocols provide guidance on when a medication may be necessary; however, the final decision of which medication to administer to a patient is made independently by paramedics. This study sought to describe the clinical decision-making process of prehospital behavioral emergencies when paramedics consider chemical restraints, and determine the factors associated with choosing specific medications to administer. Methods. Paramedics from a Midwest County in the United States were surveyed in November of 2019. The survey consisted of two open-ended questions, measuring paramedics' clinical decision-making process and factors that they considered when selecting a medication. An immersion-crystallization approach was used to analyze the interviews. Results. There was a 53% (79/149) response rate. Six themes emerged regarding the paramedics' decisions to use medication for cases involving patients with behavioral emergencies: safety of the patients and paramedics; inability to use calming techniques; severity of the behavioral emergency; inability to assess the patient due to presentation; etiology of the behavioral episode; and other factors, such as age, size, and weight of the patient. Six themes emerged regarding factors paramedics considered when choosing which medication to use in behavioral emergencies: etiology of the behavioral emergency, patient presentation, the patient's history, the patient's age, desired effect and intended outcome of the medication, and other factors. Conclusion. This study suggests there are several factors, such as safety and the etiology of the behavioral emergency, that contributed to paramedics' decision-making. The results of this study could help Emergency Medical Services administrators in revising behavioral emergency protocols.

Dosimetric impact of applicator displacement on three-dimensional image-guided high-dose-rate brachytherapy treatments for cervical cancer.

Purpose: To determine the dosimetric impact of brachytherapy applicator displacement during intracavitary (IC) and combined intracavitary/interstitial (IC/IS) high-dose-rate brachytherapy in the treatment of cervical cancer. Material and methods: Data from 27 consecutively treated patients undergoing IC or IC/IS high-dose-rate brachytherapy with tandem and ovoid-based applicators at a single academic medical center were analyzed. Virtual applicator displacements (a single shift of whole applicator with tandem/ovoid/associated needles) of 0 (clinical position), 2, 5, 7, and 10 mm in the inferior direction were modeled on treatment planning CT or MRI scans, with maintaining the same dwell times. Radiation dose to target volumes (D90 of high-risk clinical target volume) and organs at risk (OARs) (D0.1cc, D1cc, and D2cc of bladder, rectum, and sigmoid) were calculated for each virtual applicator shift, and significance of displacements was assessed using general linear model and Kruskal-Wallis test. Results: Mean dose to high-risk clinical target volume (HR-CTV) D90 was 95.7%, 88.9%, 84.6%, and 77.1% of the prescribed dose in clinical position with displacements of 2, 5, 7, and 10 mm, respectively. Rectal D2cc significantly increased by 28% and 44% at displacement of 7 mm and 10 mm, respectively. IC/IS cases showed relatively greater dosimetric differences than IC cases, with HR-CTV D90 doses of 94.4%, 85.8%, 80.4%, and 72.4% at virtual displacements of 2, 5, 7, and 10 mm, respectively. Conclusions: Applicator displacements of 5 mm or greater result in statistically significant and clinically meaningful decreases in radiation dose to HR-CTV during 3-dimensional high-dose-rate brachytherapy treatment planning, with corresponding increase in radiation dose to the rectum. IC/IS applicator displacements lead to relatively greater differences than those of IC applicators.

The impact of social rhythm and sleep disruptions on waist circumference after job loss: A prospective 18-month study.

OBJECTIVE: This study prospectively examined change in waist circumference (WC) as a function of daily social rhythms and sleep in the aftermath of involuntary job loss. It was hypothesized that disrupted social rhythms and fragmented/short sleep after job loss would independently predict gains in WC over 18 months and that resiliency to WC gain would be conferred by the converse. METHODS: Eligible participants (n = 191) completed six visits that included standardized measurements of WC. At the baseline visit, participants completed the social rhythm metric and daily sleep diary and wore an actigraph on their nondominant wrist each day for a period of 2 weeks. RESULTS: When controlling for obesity and other covariates, WC trajectories decreased for individuals with more consistent social rhythms, more activities in their sdiocial rhythms, and higher sleep quality after job loss. WC trajectories did not change for individuals with lower scores on these indicators. CONCLUSIONS: The frequency and consistency of social rhythms after job loss play a key role in WC loss. These findings support the implementation of social rhythm interventions after job loss, a potentially sensitive time for the establishment of new daily routines that have an impact on metabolic health.

Evaluation of call volume and negative emotions in emergency response system telecommunicators: a prospective, intensive longitudinal investigation.

Emergency telecommunicators are essential first responders tasked with coordinated communication within the emergency response system (ERS). Despite their exposure to significant job demands, little is known about the effect of call load or call type on emotional state within these workers. Therefore, we employed a prospective, intensive longitudinal design to examine whether emergency-eligible call volume would lead to higher intensity negative emotions post-shift when controlling for pre-shift negative emotions and a number of other work and individual factors, including work duration and night shift. A total of 47 ERS telecommunicators (dispatchers, operators, other) completed ratings over working shifts within a two-week period. Call frequency was gathered through the agency Computer-Assisted Dispatch database. Negative emotions of irritation, stress, worry, and fatigue were measured through the Visual Analogue Scale administered before and after shift. Mixed linear modeling demonstrated that telecommunicators who received more calls per hour (Estimate = 3.56, SE = 1.44, p < 0.05) and more-than-usual calls per hour (Estimate = 1.97, SE = .94, p < 0.05) had higher levels of post-shift irritability. Longer-than-usual working hours also predicted higher levels of post-shift irritability (Estimate = 1.32, SE = 0.59, p < 0.05). Call volume did not predict other negative emotions, although secondary analyses demonstrated that a larger number of chronic calls lead to greater levels of post-shift worry. ERS telecommunication agencies aiming to reduce negative emotions in workers may benefit from implementing policies and programs that target working hours, call load, and work-life balance.
