PubMed Basics: A Wealth of Scholarly Knowledge for Researchers and Doctors

April, 2019

A free resource that comprises more than 29 million citations for biomedical literature from the US National Library of Medicine — MEDLINE (a premier bibliographic database). It is developed and maintained by the National Center for Biotechnology Information (NCBI). The recent years have witnessed the modern advances in technology and internet has become a vital source for medical information. Health information in PubMed provides all aspects of record management, which includes data collection, standards, coding, integrity, and privacy of health information. Medical professionals, students, post graduates, and researchers stay updated with the latest information in the medical industry. Medical professionals use such type of information to understand detailed analysis and to facilitate appropriate healthcare delivery and patient safety. The information also supports physicians to take right decision during complex situations.

Health research with PubMed search tool acts as an integral part to the practice of many healthcare professionals. Most of the data collated is incorporated from clinical prevention and population health activities. This free source brings an in-depth analytical work performed by various medical sources allowing doctors and other health related professionals to understand and relate their cases with specific treatment. There are multiple section of contents that provide information related to clinical searchers, systematic reviews or medical genetic searches, how to expand the search (citations) or advanced search. Search in PubMed requires some basic understanding in order to retrieve the right data an individual is looking for, the usage of right word or a truncated term is important to map the specific information. For instance: a truncated term ‘tox’ if searched produces more than 600 variations and a warning message is displayed to lengthen the root word to enable all the relevant findings. Truncating a word in a multi-word may result in unexpected phrase search that may not be relevant for the data you need. Likewise, there are multiple simple techniques that help one to understand and retrieve the right information and minimize the search time for any scientific data.

Modern advances in technology has influenced a rapid growth of research capacity in producing large-scale biomedical data, which has helped healthcare professionals in managing health-related issues. Clinical effectiveness of research data is one of the important aspects of medical treatments as it acts as a liaison between the development of newer treatments and innovative therapies to improve human health. As the number of treatment options grow, the range of clinical effectiveness evidence increases, which is essential for safe and efficient healthcare systems. This has enabled the expansion of vast scientific knowledge that is inefficiently interpreted from scientific lab to clinical practice.

There are various tools that will be used in PubMed Search:

  • PubMed Mobile

  • Single Citation Matcher

  • Batch Citation Matcher

  • Clinical Queries

  • Topic-Specific Queries


The question is how effectively this resource is utilized and with the present amount of demand at hand it is important what type of tools can be used and evidence-based data will enable professionals in implementing better clinical prevention and practice.
