Reduction of Hospital-Acquired Infections Through a Nursing Education Program: A Quality Improvement Project on the Sensitization of Nursing Staff Toward Infection Control in Neonates

Background This study aimed to reduce hospital-acquired infections (HAIs) by at least 50% in our unit through a nursing education program to sensitize the nursing staff toward infection control in neonates. Methodology This pre- and post-intervention observational study was conducted in Liaquat National Hospital's Neonatal Intensive Care Unit (NICU) from October 2021 until March 2023. This observational study was conducted in three phases. In phase I (pre-implementation), all neonates with suspected HAIs were included. In phase II (implementation), the nursing staff dedicated to the NICU were trained. In phase III (post-implementation), all neonates with suspected HAIs were included. Culture-proven bloodstream infections (BSIs), urinary tract infections (UTIs), and ventilator-associated pneumonia (VAP) were the three types of HAIs. The nursing scoring was done by the principal investigator based on a questionnaire. The Shapiro-Wilk test was used to evaluate the normality of all quantitative data across all phases. Results In the pre-implementation phase, there were 24 (10.8%) HAIs, among which 19 (8.6%) were BSIs, one (0.5%) was a catheter-associated urinary tract infection (CAUTI), and seven (3.2%) were VAP. Whereas in the post-implementation phase, there were 12 (5%) HAIs, among which 10 (4.1%) were BSIs, none were CAUTIs, and five (2.1%) were VAP. There was a significant reduction of HAIs in the post-implementation phase (p < 0.01). The difference in the knowledge, assessment, and practice was statistically significant in the post-implementation phase (p < 0.01). Conclusions We established a successful cost-effective intervention to improve the awareness and compliance of NICU nurses with infection control practices. This helped us in reducing HAIs in our NICU.

Defining and evaluating the Hawthorne effect in primary care, a systematic review and meta-analysis

In 2015, we conducted a randomized controlled trial (RCT) in primary care to evaluate if posters and pamphlets dispensed in general practice waiting rooms enhanced vaccination uptake for seasonal influenza. Unexpectedly, vaccination uptake rose in both arms of the RCT whereas public health data indicated a decrease. We wondered if the design of the trial had led to a Hawthorne effect (HE). Searching the literature, we noticed that the definition of the HE was unclear if stated. Our objectives were to refine a definition of the HE for primary care, to evaluate its size, and to draw consequences for primary care research. We designed a Preferred Reporting Items for Systematic reviews and Meta-Analyses review and meta-analysis between January 2012 and March 2022. We included original reports defining the HE and reports measuring it without setting limitations. Definitions of the HE were collected and summarized. Main published outcomes were extracted and measures were analyzed to evaluate odds ratios (ORs) in primary care. The search led to 180 records, reduced on review to 74 for definition and 15 for quantification. Our definition of HE is "an aware or unconscious complex behavior change in a study environment, related to the complex interaction of four biases affecting the study subjects and investigators: selection bias, commitment and congruence bias, conformity and social desirability bias and observation and measurement bias." Its size varies in time and depends on the education and professional position of the investigators and subjects, the study environment, and the outcome. There are overlap areas between the HE, placebo effect, and regression to the mean. In binary outcomes, the overall OR of the HE computed in primary care was 1.41 (95% CI: [1.13; 1.75]; I 2 = 97%), but the significance of the HE disappears in well-designed studies. We conclude that the HE results from a complex system of interacting phenomena and appears to some degree in all experimental research, but its size can considerably be reduced by refining study designs.
