Using Family Members as Medical Interpreters: An Explanation of Healthcare Practitioners’ Normative Practices in Pediatric and Neonatal Departments in Australia

ABSTRACT

Both international tourism and migration of people with low English proficiency (LEP) to Australia are increasing. Thus, health-care practitioners (HPs) increasingly use interpreters to communicate with patients with LEP. Although qualified interpreters are the most suggested and policy-endorsed mechanism for communicating with patients with LEP, family members (FMIs) are also used as interpreters. This study investigated (a) when do health professionals consider it appropriate to use FMIs and (b) what characteristics of family members health professionals believe make them suitable to act as FMIs. As part of a larger project examining the decision-making processes of HPs regarding interpreter use, 69 HPs from neonatal and pediatric departments in one hospital in Queensland Australia were interviewed. Results indicated HPs thought the appropriateness of using FMIs depended on the type of information, such that it was either completely acceptable (e.g., explaining some basic or non-medical information) or completely unacceptable (e.g., confidential information or consent). However, in an emergency, when no other options were available, FMIs were used. The characteristics of suitable FMIs included age, level of English proficiency and medical understanding, and the relationship between patient and FMI. Results were to some extent consistent with Queensland government policies but there were notable differences, including using children and regarding FMIs as first preference. Improving HP’s knowledge of policies may increase their confidence in their practice and appropriate use of FMIs, thereby improving their care delivery to patients and families with LEP.     

Electrocardiogram Interpretation Training and Competency Assessment in Emergency Medicine Residency Programs

OBJECTIVES: To determine the type of electrocardiogram (ECG) interpretation instruction in emergency medicine (EM) residency programs, the use and perceived value of teaching modalities and resources, and the methods used to assess competency of ECG interpretation. METHODS: An interactive survey instrument was posted on the Internet using SurveySuite, Inc., software and e-mailed to program directors (PDs) of all 125 Accreditation Council for Graduate Medical Education-approved U.S. EM residency programs. Responses are reported in total numbers and percentages. RESULTS: Ninety-nine of 125 PDs completed the online survey (response rate, 79.2%). Emergency department instruction (99%), case-based lectures (98%), and didactic lectures (98%) were most commonly used to teach interpretation of ECGs, followed by computer-based instruction (34%) and ECG laboratory (12%). The majority of programs (53%) spent more than eight hours on formal ECG lectures per year, while 11% spent less than three hours. Observation during clinical time (99%), lecture time (76%), and hypothetical cases (57%) were the most common ways to determine competency in reading ECGs, while clinical observation and hypothetical cases were perceived as the most valuable. The most commonly used resource was personal or departmental ECG files (91%), and this had the highest perceived value. The majority of PDs were comfortable with residents' abilities to read ECGs by the third year (96%) and fourth year (91%) of residency. CONCLUSIONS: These data suggest that EM PDs believe that EM residency is adequately preparing graduates to interpret ECGs. This goal is achieved through a variety of methods.

Lessons from RUTH.

The Raloxifene Use for The Heart (RUTH) trial was designed to investigate possible cardioprotective effects of raloxifene in elderly women with coronary artery disease (CAD) or at risk for CAD. While RUTH results demonstrated a neutral effect on CAD risk during 5.6 years of follow-up, they also open a debate whether primary prevention of fractures or breast cancer by raloxifene is justified in view of the serious adverse events which were recorded in this trial. Furthermore, the absolute numbers of saved events (breast cancer and clinical vertebral fractures) or added events (stroke and venous thromboembolism) were in the order of only 1 case per 1,000 treated women/year, a figure which should be evaluated on a pharmacoeconomic scale as well.     

Halofuginone--an inhibitor of collagen type I synthesis--prevents postoperative formation of abdominal adhesions.

OBJECTIVE: To evaluate the effects of halofuginone, a specific inhibitor of collagen type I synthesis, on the postoperative formation of abdominal adhesions in rats. SUMMARY BACKGROUND DATA: Postoperative adhesions remain the leading cause of small bowel obstruction in the Western world. Surgical trauma causes the release of a serosanguineous exudate that forms a fibrinous bridge between two organs. This becomes ingrown with fibroblasts, and subsequent collagen deposition leads to the formation of a permanent adhesion. Most of the drugs used have been clinically ineffective, and none has been specific to a particular extracellular matrix molecule. Therefore, there are serious concerns about the toxic consequences of interfering with the biosynthesis of other collagens, other matrix proteins, or vital collagen-like molecules. METHODS: Adhesions were induced by scraping the cecum until capillary bleeding occurred. The adhesions were scored 21 days later. Halofuginone was either injected intraperitoneally (1 microg/25 g body weight) every day, starting on the day of operation, or added orally at concentrations of 5 or 10 mg/kg, starting 4 days before the operation. Collagen alpha1(I) gene expression was evaluated by in situ hybridization, total collagen was estimated by Sirius red staining, and collagen type III was detected by immunohistochemistry. RESULTS: The adhesions formed between the intestinal walls were composed of collagen and were populated with cells expressing the collagen alpha1(I) gene. Regardless of the administration procedure, halofuginone significantly reduced the number and severity of the adhesions. Halofuginone prevented the increase in collagen alpha1(I) gene expression observed in the operated rats, thus reducing collagen content to the control level. In fibroblasts derived from abdominal adhesions, halofuginone induced dose-dependent inhibition of collagen alpha1(I) gene expression and collagen synthesis. Collagen type III levels were not altered by adhesion induction or by halofuginone treatment. CONCLUSIONS: Upregulation of collagen synthesis appears to have a critical role in the pathophysiology of postoperative adhesions. Halofuginone, an inhibitor of collagen type I synthesis, could be used as an important tool in understanding the role of collagen in adhesion formation, and it may become a novel and promising antifibrotic agent for preventing postoperative adhesion formation.     

Gender paradox in cardiac calcium deposits in middle-aged and elderly patients: mitral annular and coronary calcifications interrelationship

OBJECTIVES: mitral annular calcification (MAC) occurs mainly in middle-aged and elderly patients and can lead to serious clinical consequences. Male predominance in the prevalence of coronary disease is well-established. Paradoxically, the prevalence of MAC, which is theoretically based on the same etiological mechanisms as coronary atherosclerosis, seems to be predominant in postmenopausal women. The goal of this work was to investigate gender influences on interrelationship between MAC and coronary calcifications (CC) in the same population of middle-aged and elderly patients with increased cardiovascular risk. METHODS: the study comprised 522 patients (284 men and 238 postmenopausal women, aged 52-80 years, mean 65+/-6), who were recruited to the International Nifedipine GITS Study of Intervention as a Goal in Hypertension Treatment (INSIGHT) study in our region. They underwent both fast spiral computed tomography of the heart and echo-Doppler. MAC was defined as advanced when its thickness was > or =5mm; otherwise it was defined as trivial. RESULTS: there were 37 (16%) women and 25 (9%) men with advanced MAC (AMAC), 97 (41%) women and 118 (42%) men with trivial MAC and 104 (44%) women and 141 (50%) men without MAC. The prevalence of any type of CC was significantly higher among men (P=0. 001). In sharp contrast to the distinct male predominance in coronary disease, AMAC was more prevalent among women. In patients without CC prevalence was 9 and 4%, increasing to 16 and 8% in those with nonsevere CC and to 38 and 14% in patients with severe CC, respectively (P=0.001). Multivariate analysis showed that AMAC can predict the presence of severe CC in women and men, with OR of 4.1 and 2.6 (CI 1.2-14.8 and 1.0-10.6) and coronary disease with OR of 2. 5 and 2.5 (CI 0.6-10.6 and 1.0-6.4), respectively. CONCLUSIONS: AMAC signifies a high probability of coronary atherosclerosis in patients of both genders. The inverted gender predominance in the prevalence of annular calcification and CC could be explained by additional etiological (likely osteoporotic) mechanisms of MAC development among postmenopausal women.
