Why get a DSS?

As scientific research becomes increasingly data-driven, libraries are expanding their data services. Medical librarians and other health information professionals are ideally situated in the research and information-seeking process to provide data services support.

Your DSS shows employers, colleagues and researchers and others who work with data that:

  • You have skills in providing a range of data services
  • You are committed to offering quality data services
  • You are committed to staying current with developments in data management and data services.

A Basic DSS certificate gives you a solid grounding in all areas of the competency and the flexibility to choose additional learning based on your interests.

These skills are designed for a wide range of librarians, such as:

  • Public librarians
  • Medical librarians
  • Librarians working in the consumer health environment.

An Interview with Dr. Emily Vardell

Below describes Dr. Emily Vardell's experience and accomplishments in teaching her MLA-approved course.

What was your experience going through the process of getting your course approved?

“I worked with Debra Cavanaugh from MLA who helped me go through the process. She sent me the CHIS competencies and I reviewed my syllabus to make sure the elements were there. Luckily, my syllabus was already perfectly aligned with the CHIS competencies. We were able to cover a lot of content in my 12 week-long class and the CHIS competencies perfectly aligned and made sense to teach in a consumer health course. I had to submit my syllabus to Debra for review to make sure everything was aligned with the CHIS competencies and all the other required information was included. It was pretty seamless.”

“It is pretty easy for students to access their CHIS certification once they’ve completed the course. At the end of the semester, I would provide students with step-by-step instructions on how to obtain their certification with the code needed to access it. It was helpful and easy to follow and It’s not a super long process.”

What would you suggest to professors interested in getting their course approved?

“It is really a great benefit to offer to students that already connects them to practice. Often times people say, ‘Library School is so theoretical. I’m not seeing the practical applications.’ CHIS, however, offers that practical application because its certification students can earn before they graduate. It helps them secure that position that gives them the ‘leg-up’ in a job interview setting.”

“CHIS is a great way to attract students to courses that are overlooked or never looked at twice because students would assume, 'Oh, this is a health class, not for me.' Having that extra level of connecting public libraries helps.”

“Make sure to keep MLA updated on what's going on. Send them a list of students, give further communication with the Regional Medical Library. NNLM helps get everything completed and ready to go.”

Student’s Feedback

“When I enrolled in the SLIM program through Emporia, I did not set out to earn the CHIS certification. Having a professor my first semester that was a former medical librarian piqued my interest. My background is in teacher education, and while I taught, I would use my summers and weekends to work in healthcare. As my life evolved to librarianship, I have continued to use my sum experiences to inform my philosophy and mindset. Long ago, I realized that the hope to change lives for the better rested in education. This class affirms my beliefs. I know that I can make differences in the lives of library patrons by sharing what I have learned and by advocating for those individuals whose voices are rarely heard. Thank you NNLM and Dr. Vardell for making this certification possible.”

What motivated you to sign up for this class?

“I love working in a public library and would love to continue on that path, but I'm open to other possibilities should opportunities arise. I decided to sign up for this class because I am interested in earning my CHIS and enjoyed the last class I took taught by professor Vardell.”

“I decided to take this class because my current library manager has informed me that there are very few people employed by the county with any consumer health information know how. With this under my belt, and the benefit of the CHIS, I will have a much higher chance of acquiring a better job than the one which I currently hold.”

“I have probably looked at every possible conceivable source for health information from Google to PubMed to National Libraries of Medicine (NLM). I have taken several courses/webinars through NLM and am currently enrolled in a "Wellness in the Library Workplace" course. My goal was to earn my CHIS which is "reason 3" why I am taking this course.”

“I really like being in the public library and I will probably stay in that area, although if the right opportunity in a different library came up I would be up to try it. I am taking this class because I want my CHIS certification. I also know an awesome medical librarian so I using this class to explore the possibilities of medical librarianship.”

Additional feedback from Dr. Emily Vardell

“I am so grateful for the RML’s financial support. It would be a barrier to students if they had to cover the fees. There are more students taking advantage of the certification because of the RML covering the fees.”
