Central line infections

Central line infections are one of the common issues we face in the health care industry. In the facility I work, we had three cases this year. We are trying to decrease the infection rate by educating staff and patients. We currently use a Chlorhexidine (CHG) bath on all patients with central lines. Studies show that bathing with 2% CHG led to evident CLABSI reduction (Deigo et al., 2021). The decrease in HAIs was found to be greater than bathing with soap and water (Rubin et al.,2013). This led me to formulate my PICOT question.

In hospitalized patients with central lines(P), what is the effect of Chlorhexidine baths (I) on decreasing central line-associated bloodstream infection (CLABSI) (O) compared with regular baths with soap and water (C) while hospitalized (T)

Database used

CINAHL plus full text and Medline with full text

Search terms used

Central line-associated bloodstream infections, Central line infection prevention, Central line, AND associated bloodstream infection, Central line infections AND soap and water, Central line infections chlorhexidine baths.

Search Results

CINAHL plus full text produced 133 results, while Medline with full text produced 190 results (Walden Library n.d.-a). These two databases produced original research and peer-reviewed articles. I restricted my search to produce articles within five years. Articles were geared toward my research question and related to chlorhexidine bath vs. soap and water to reduce central line infections. These are common occurrences for central line infection if proper infection control measures are not in place.

 Addition of Boolean Operator

Adding Boolean operator to my search decreased my results greatly. Boolean operators and nesting help me search for combinations of words or phrases processed in a specified order. For greater precision, I use parentheses to group portions of complex Boolean expressions in the EXPERT option of Keyword Search. Terms inside parentheses are processed first (Library of Congress, n.d.).

Strategies to increase rigor and effectiveness of a database search

Some strategies used to increase the effectiveness of a database search include asking a Librarian and using parenthesis and Boolean operators. This will help me search for relevant documents that are more focused to my PICOT question.  Another strategy I used was to limit my search to at least five years to get  more updated materials.
