The dis- advantage is that depositions take time away from your practice purchase 200mg celebrex free shipping, and it is hard to listen to an expert impugning you celebrex 200mg on line. If you do sit in on a deposition and something is said on which you want to comment to your lawyer generic 100mg celebrex with mastercard, make a note of it and discuss it with him or her in private celebrex 100mg without prescription. Before your trial, read your deposition carefully, and virtually memo- rize it so that you will be consistent at trial. Before your court date, visit the courtroom to familiarize yourself with the setting. Plan on attending the entire trial, demonstrating that you care about the case. It is also reasonable to have your spouse attend the trial once or twice to show your human side. When sitting in the court- room and during other testimony, make eye contact with the jury. Identify inaccuracies made by other witnesses or points that can be used by your attorney, which can be discussed with your attorney when there is a break in the case. The following are some guidelines on handling yourself at trial (see the Discovery: Deposition section for how to answer questions posed by the plaintiff attorney)(1–3,8–10). Men are encouraged to wear dark suits, and subtle ties, but not bow ties, which have an eccentric connotation. Turn to face the lawyer when he or she poses a question and then turn to the jury to answer the question. Do not use medical terminology that the jury will not understand, but also try not to talk down to the jury. The use of models, diagrams, and photographs can help illustrate points clearly. The plaintiff attorney will try to chal- lenge your reputation and make you nervous. Jurors expect attorneys to be arrogant and aggressive, in part based on portrayals of attor- neys by the media. I have been involved in several cases in which the same attorney who grilled me on one case asked if he could hire me on a different case because I did such a good job under fire at a deposition. If you recog- nize that these attorneys are only doing what is expected of them, it may help in removing some of the emotion from the situation. Outside the courtroom, either before, during, or after breaks, always retain your professional demeanor. Jurors could see you and think that you are not taking the case seri- ously. Also, do not talk about the case until your lawyers says it is okay, because the other side can pick up remarks. ACKNOWLEDGMENT This is an excerpt from an article entitled “Pathologists and the Judi- cial Process: How to Avoid It” by Jonathan I. This por- tion of the article was selected because it explains so well the purpose of pretrial discovery and provides valuable insight into the conduct of a deposition. Discover strategies for avoiding legal pitfalls if you must ever give a deposition. Chapter 6 / Communication and Patient Safety 63 III THE CLINICAL FACE OF LITIGATION 64 Gorney Chapter 6 / Communication and Patient Safety 65 6 Communication and Patient Safety Mark Gorney, MD SUMMARY Faulty communication is among the most common underlying causes of medical error and frequently erodes the doctor–patient relationship. Communication should be understood in the broad- est sense, including nonverbal, oral, and written. This chapter reviews the most common mechanisms responsible for commu- nication failures and recommends specific routines to minimize or avoid them altogether. Key Words: Poor listening habits; nonverbal; speech tempo; body language; repetition. INTRODUCTION Patient anger underlies many malpractice claims and frequently results from ineffective communication. The breakdown is usually between doctor and patient but may also involve miscommunica- tion between physicians and nurses or between physicians and family members.
