Assessment of email communication skills of rheumatology fellows: a pilot study.

Physician-patient email communication is gaining popularity. However, a formal assessment of physicians' email communication skills has not been described. We hypothesized that the email communication skills of rheumatology fellows can be measured in an objective structured clinical examination (OSCE) setting using a novel email content analysis instrument which has 18 items. During an OSCE, we asked 50 rheumatology fellows to respond to a simulated patient email. The content of the responses was assessed using our instrument. The majority of rheumatology fellows wrote appropriate responses scoring a mean (±SD) of 10.6 (±2.6) points (maximum score 18), with high inter-rater reliability (0.86). Most fellows were concise (74%) and courteous (68%) but not formal (22%). Ninety-two percent of fellows acknowledged that the patient's condition required urgent medical attention, but only 30% took active measures to contact the patient. No one encrypted their messages. The objective assessment of email communication skills is possible using simulated emails in an OSCE setting. The variable email communication scores and incidental patient safety gaps identified, suggest a need for further training and defined proficiency standards for physicians' email communication skills.

Salt, aldosterone, and insulin resistance: impact on the cardiovascular system.

Hypertension and type 2 diabetes mellitus (T2DM) are powerful risk factors for cardiovascular disease (CVD) and chronic kidney disease (CKD), both of which are leading causes of morbidity and mortality worldwide. Research into the pathophysiology of CVD and CKD risk factors has identified salt sensitivity and insulin resistance as key elements underlying the relationship between hypertension and T2DM. Excess dietary salt and caloric intake, as commonly found in westernized diets, is linked not only to increased blood pressure, but also to defective insulin sensitivity and impaired glucose homeostasis. In this setting, activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS), as well as increased signaling through the mineralocorticoid receptor (MR), result in increased production of reactive oxygen species and oxidative stress, which in turn contribute to insulin resistance and impaired vascular function. In addition, insulin resistance is not limited to classic insulin-sensitive tissues such as skeletal muscle, but it also affects the cardiovascular system, where it participates in the development of CVD and CKD. Current clinical knowledge points towards an impact of salt restriction, RAAS blockade, and MR antagonism on cardiovascular and renal protection, but also on improved insulin sensitivity and glucose homeostasis.
