This article in the September 2009 Annals of Emergency Medicine: Patient Satisfaction as a function of Emergency Department Previsit Expectations points out, once again, the importance of interpersonal skills often can be more important than what you know and what skills you have as a physician. I am confident this applies to most occupations.
Books such as How to Win Friends and Influence People can help us to be better husbands, friends, parents, and professionals by focusing on interpersonal skills. I strongly recommend this book.
