Psychosocial Risk Factors for Hypertension: an Update of the Literature

A growing body of research demonstrates that psychosocial factors play an important role in the development of hypertension. Previous reviews have identified several key factors (i.e., occupational stress) that contribute to the onset of hypertension; however, they are now outdated. In this review, we provide an updated synthesis of the literature from 2010 to April 2014. We identified 21 articles for inclusion in the review, of which there were six categories of psychosocial stressors: occupational stress, personality, mental health, housing instability, social support/isolation, and sleep quality. Sixteen of the studies reported an association between the psychosocial stressor and blood pressure. While several findings were consistent with previous literature, new findings regarding mediating and moderating factors underlying the psychosocial-hypertension association help to untangle inconsistencies reported in the literature. Moreover, sleep quality is a novel additional factor that should undergo further exploration. Areas for future research based on these findings are discussed.

Health care workers and disaster preparedness: barriers to and facilitators of willingness to respond

BackgroundThere is limited research on preparation of health care workers for disasters. Prior research addressed systems-level responses rather than specific institutional and individual responses.MethodsAn anonymous online survey of hospital employees, who were grouped into clinical and non-clinical staff, was conducted. The objective of this study was to compare perceptions of clinical and non-clinical staff with regard to personal needs, willingness to report (WTR) to work, and level of confidence in the hospital‘s ability to protect safety and provide personal protective equipment (PPE) in the event of a disaster.ResultsA total of 5,790 employees were surveyed; 41 % responded (77 % were women and 63 % were clinical staff). Seventy-nine percent either strongly or somewhat agreed that they know what to do in the event of a disaster, and the majority was willing to report for duty in the event of a disaster. The most common barriers included ‘caring for children’ (55 %) and ‘caring for pets’ (34 %). Clinical staff was significantly more likely than non-clinical staff to endorse childcare responsibilities (58.9 % vs. 48 %) and caring for pets (36 % vs. 30 %, respectively) as barriers to WTR. Older age was a significant facilitator of WTR [odds ratio (OR) 1.49, 95 % CI: 1.27-1.65]. Non-clinical staff was more confident in the hospital’s ability to protect safety and provide PPE compared to clinical staff (OR 1.43, 95 % CI: 1.15-1.78).ConclusionClinical and non-clinical staff differ in the types of barriers to WTR endorsed, as well as their confidence in the hospital’s ability to provide them with PPE and guarantee their safety.

Enhancing adherence of antihypertensive regimens in hypertensive African–Americans: current and future prospects

Patient adherence to antihypertensive medication is an important strategy for blood pressure control in hypertensive patients. However, rates of antihypertensive medication adherence among hypertensive African–Americans are unacceptably low. This article examines the current understanding of patient, clinical, provider and healthcare system factors associated with medication adherence in hypertensive African–Americans. Studies demonstrated that patient and clinical factors, such as self-efficacy and depression, are consistently associated with medication adherence in hypertensive African–Americans patients. Provider communication shows promise as a correlate of medication adherence, but more research on provider and healthcare system factors are still needed. The authors recommend that interventions targeted at increasing medication adherence among hypertensive African–Americans focus on self-efficacy. It is also imperative that clinicians screen hypertensive patients for depression and treat, if necessary.

Development and evaluation of a novel, real time mobile telesonography system in management of patients with abdominal trauma: study protocol

BackgroundDespite the use of e-FAST in management of patients with abdominal trauma, its utility in prehospital setting is not widely adopted. The goal of this study is to develop a novel portable telesonography (TS) system and evaluate the comparability of the quality of images obtained via this system among healthy volunteers who undergo e-FAST abdominal examination in a moving ambulance and at the ED. We hypothesize that: (1) real-time ultrasound images of acute trauma patients in the pre-hospital setting can be obtained and transmitted to the ED via the novel TS system; and (2) Ultrasound images transmitted to the hospital from the real-time TS system will be comparable in quality to those obtained in the ED.MethodsStudy participants are three healthy volunteers (one each with normal, overweight and obese BMI category). The ultrasound images will be obtained by two ultrasound-trained physicians The TS is a portable sonogram (by Sonosite) interfaced with a portable broadcast unit (by Live-U). Two UTPs will conduct e-FAST examinations on healthy volunteers in moving ambulances and transmit the images via cellular network to the hospital server, where they are stored. Upon arrival in the ED, the same UTPs will obtain another set of images from the volunteers, which are then compared to those obtained in the moving ambulances by another set of blinded UTPs (evaluators) using a validated image quality scale, the Questionnaire for User Interaction Satisfaction (QUIS).DiscussionFindings from this study will provide needed data on the validity of the novel TS in transmitting live images from moving ambulances to images obtained in the ED thus providing opportunity to facilitate medical care of a patient located in a remote or austere setting.

Promoting tobacco cessation utilizing pre-health professional students as research associates in the emergency department

OBJECTIVE The objective of this study was to investigate the extent to which volunteer research associates (RAs) can be utilized to screen emergency department patients and their visitors for tobacco use and effectively refer tobacco users requesting help to state Tobacco Quitlines. METHODS A sample of 19,149 individuals in 10 emergency departments around the country was enrolled into a prospective, interventional study on tobacco cessation by pre-health professional RAs. Participants who screened positive for tobacco use were provided a brief description of Tobacco Quitline programs and then offered a faxed referral to their respective state Quitline. RESULTS A total of 10,303 (54%) participants reported tobacco use for more than one month during their lives, with 3861 (20%) currently using every day and an additional 1340 using on some days (7%). Most importantly, 2151 participants requested a faxed Tobacco Quitline referral (36% of individuals who used tobacco in the past month). DISCUSSION Pre-health professional RAs were shown to be an effective and cost-efficient resource for providing a strongly recommended service in the emergency department. Patient care (and the care of their visitors) was supplemented, emergency department personnel were not provided with additional burden, and RAs were provided with valuable experience for their futures in the health professions.

Body Mass Index and Abdominal Ultrasound Image Quality A Pilot Survey of Sonographers

The objective was to assess the consensus among sonographers that the quality of abdominal ultrasound (US) images is related to the patient’s body mass index (BMI). Fourteen sonographers completed a 12-item questionnaire to evaluate their experience with abdominal US imaging with respect to image quality in correlation with the patient’s adipose tissue. Of the sonographers sampled, 85.7% agreed that there is an association between the amount of adipose tissue on a patient’s abdomen and the quality of US image obtained; 85.7% also agreed that a normal BMI of 18.5 to 24.9 provides the best US image. However, only 28.6% agreed that normal amounts of adipose tissue produce poor image quality. There appears to be agreement among sonographers that BMI is a factor in obtaining good quality abdominal US images. The general consensus was that the best abdominal US images were obtained in patients with normal BMI, whereas images obtained from patients with BMI 30.0 to 34.9 and to a lesser extent BMI 25.0 to 29.9 were limited in quality.

Demonstration of novel, secure, real-time, portable ultrasound transmission from an austere international location

There is not sufficient access to medical care or medical expertise in many parts of the world. An innovative telemedicine system has been developed to provide expert medical guidance to field caregivers [who have less medical expertise but can reach the patient population in need]. Real-time ultrasound video images have been securely transmitted from the Dominican Republic to Hackensack University Medical Center, Hackensack NJ (HackensackUMC), while the expert physician at HackensackUMC maintained direct voice communication with the field caregiver. Utilizing a portable ultrasound machine (Sonosite) integrated with portable broadcasting device (LiveU), extended Focused Assessment Sonography in Trauma (e-FAST) examinations were performed on healthy volunteers and transmitted via the local cellular network. Additionally, two e-FAST examinations were conducted from a remote location without cellular coverage and transmitted via broad ground area network (BGAN) satellites. The demonstration took the technology “out of the lab” and into a real life, austere environment. The conditions of the Dominican Republic ultrasound mission provided experience on how to manage and utilize this innovative technology in areas where reliable communications and medical coverage are not readily available. The resilient transmission capabilities coupled with the security features deem this portable Telesonography (TS) equipment highly useful in the telemedicine forefront by offering healthcare in underdeveloped areas as well as potentially enhancing throughput in disaster situations.

Patient-Centered Communication Behaviors That Correlate With Higher Patient Satisfaction Scores:

Background: With increased emphasis on improving the patient experience, clinicians are being asked to improve their patient-centered communication behaviors to improve patient satisfaction (PS) scores. Local Problem: The relationship between clinician communication behaviors and PS is poorly studied in the emergency department (ED) setting. The purpose of this study was to identify whether specific communication behaviors correlate with higher PS scores in the ED setting. Methods: During a quality improvement project, we performed 191 bedside observations of ED clinicians during their initial interaction with patients and recorded the frequency of 8 positive communication behaviors as defined by the PatientSET tool. Interventions: The frequency of use of the PatientSET communication behaviors was compared between known high performers in Press Ganey PS scores versus low performers. Results: Being a high Press Ganey performer was associated with a significantly higher frequency of performance in 6 of the 8 PatientSET communication behaviors. Conclusions: Positive communication behaviors such as those in the PatientSET tool occurred more frequently in ED clinicians with higher PS scores.

Evaluation of a Novel Wireless Transmission System for Trauma Ultrasound Examinations From Moving Ambulances

Objective To determine if physicians trained in ultrasound interpretation perceive a difference in image quality and usefulness between Extended Focused Assessment with Sonography ultrasound examinations performed at bedside in a hospital vs. by emergency medical technicians minimally trained in medical ultrasound on a moving ambulance and transmitted to the hospital via a novel wireless system. In particular, we sought to demonstrate that useful images could be obtained from patients in less than optimal imaging conditions; that is, while they were in transport. Methods Emergency medical technicians performed the examinations during transport of blunt trauma patients. Upon patient arrival at the hospital, a bedside Extended Focused Assessment with Sonography examination was performed by a physician. Both examinations were recorded and later reviewed by physicians trained in ultrasound interpretation. Results Data were collected on 20 blunt trauma patients over a period of 13 mo. Twenty ultrasound-trained physicians blindly compared transmitted vs. bedside images using 11 Questionnaire for User Interaction Satisfaction scales. Four paired samples t-tests were conducted to assess mean differences between ratings for ambulatory and base images. Conclusion Although there is a slight tendency for the average rating across all subjects and raters to be slightly higher in the base than in the ambulatory condition, none of these differences are statistically significant. These results suggest that the quality of the ambulatory images was viewed as essentially as good as the quality of the base images.
