MVC-AACN Newsletter FALL 2013 Hello fellow MVC AACN members, INSIDE THIS ISSUE 1-2 Letter from New Chapter President 2 NTI News 3-11 Neuro Program Review 11 Horizons Reminder 12 Step Forward Theme & Fall Program Reminder 13 Fall Education program reminder 13-14 Photos Allow me to introduce myself to those of you who don't already know me. My name is Chrissy Cebollero, and I am the current President of our chapter, and have been involved on the board over the last 4 years. I currently work at Lowell General Hospital, and have for the past 17 years. About a year ago I became an Administrative Coordinators (nursing supervisor) and for the 11 years prior had been a staff nurse in the ICU. I am married (to a nurse), and we have 3 kids in 3 different schools who are involved in more activities than I can list. I have been thinking and thinking about a theme for this year. If you follow the newsletters sent out by AACN they always have a letter with suggestions on how to apply the theme of the year or examples of how it was applied. Last year was DARE TO... and this year is STEP FORWARD... I thought of combining the two but instead have decided on BE INVOLVED! I would like to challenge you to BE INVOLVED in something important to you. It can be something small like voicing your opinion about changes on the unit where you work. It could be something bigger like joining a committee which could make practice changes hospital wide. I would love to challenge anyone of you to be involved at the board meetings, or to help plan our next program. Your involvement may not have anything to do with nursing, but something else you are interested in. (cont on page 2) Newsletter 1 continued from page 1 One event you may start with is our fall program... Bundles, Guidelines & Pearls: Sepsis, PAD and ABCDE. The all day program is being held on October 22 at the Westford Regency. Program brochures are available for download on the MVC AACN website (accessed through AACN.org). We will be having our next board meeting following the program for anyone interested in joining us. Another upcoming event is the 3 day Regional Horizons Conference. This time the venue is Portland, ME and is being held April 2, 3&4 2014. Flyers will be mailed after the New Year. You can look at HORIZONS2014.org for more information. Lead through example and BE INVOLVED in the process. Thank you and looking forward to another great year, Chrissy Cebollero BSN RN CCRN MVC AACN President A Big Thank You to All Chapter Members who volunteered their time at the NTI Ribbon Booth in Boston this past May! (Look for photos in this newsletter and on our AACN Chapter Website!) Thanks to each of you our Chapter was able to staff the Ribbon Booth for 2 days. The funds raised from NTI T-shirt sales were divided between the three AACN Chapters in eastern Massachusetts and will be used to support educational programs and philanthropic activities. Next year NTI will be held in It may only be October but watch Denver, CO from May 19-22. Be sure to stop by the Ribbon Booth in Denver to say for an announcement about the “Hello” to Chapter hosts and thank them Chapter Christmas Party! Don’t for volunteering their time to be there! forget our annual Toys for Tots Housing is open now for this event so donations too! reserve your room early!!

MVC-AACN Newsletter 11 2013-14 AACN Theme (Submitted by Ellen Stokinger – MVC Membership Chair) In May of 2013 “Step Forward” was announced at NTI as the new theme for AACN. Each year the incoming president of AACN presents a theme to carry forth in her year as president. Last year’s theme of “Dare to” … leads into this years’ theme “Step Forward”. Think of your own practice/ profession, many days as a patient advocate you have dared to step forward and say your gut feeling and you have pushed for further testing or further observation of your patient. In the rush to make beds available in ICU how often do patients get pressed to move on to step down units. Are you there to step forward and say they are not ready yet? I am sure there are many more situations to which we can carry this theme. In 1985 the Merrimack Valley Chapter started with 20 members. Now there are 120 members and growing each year. Please Step Forward and exercise your ability to show leadership traits. There are opportunities in the chapter to join a committee, attend board meetings (the Oct. meeting is after the program). Then once you are familiar with the board activities you can and should run for office. Many chapter officers have transitioned from staff to management positions possibly because they have “dared to” “step forward” “with confidence”. P.S. membership dues age 55 years and five years are reduced to $59/year; Also Submit four members for AACN renewal together and save $10 off each - see forms on AACN website. Don’t forget to renew your annual Chapter membership! Go to the AACN.org website to obtain a MVC application.
