Type of Study: the research is a qualitative study
Design Type: scholars used a grounded theory research design
Framework/Theory: no apparent theoretical framework appliedThe scholarly articles used contained studies carried out in various surgical units in different hospitals. The articles were searched using different databases such as Embase, PubMed, and Gray.Concepts: The investigators aimed at determining between 2% chlorhexidine gluconate and pavidone-iodine, which disinfectant is more effective when applied pre-operation in reducing surgical site infection post-operation.
Independent Variable: In this study, the independent variables are 2% chlorhexidine gluconate and pavidone
Dependent Variable: surgical site infections
Controlled Variable: no control variable identified
Limitations: Failure to use latest articles. Use of articles which are more than 60 years old, could lead to misinformation for having outdated information
Using six studies containing a total of 2484 participants, the researchers found that when 2% chlorhexidine gluconate was used, the surgical site infection occurred at the rate of 6.8% compared to 11% prevalence rate when pavidone-Iodine was used. Thus, they concluded that in terms of prevention of surgical site infections, 2% chlorhexidine gluconate was more effective than pavidone-iodine.The study has a level IV form of evidence(Dasgupta et al., 2015)Type of Study: the scholars applied an observational qualitative study
Design Type: The type of research design was observational
Framework/Theory: no identifiable theoretical framework applied.The researchers carried out the investigation in surgical ICU units containing 12 beds each and the study consisted of 242 patients, who stayed in these units for more than 48 hoursConcepts: The study aimed at determining the cases of nosocomial infections obtained in surgical ICU units, their risk factors, the causative agents, and their consequences in a tertiary care teaching hospital.
Independent Variable: performing operations
Dependent Variable: presence of nosocomial infections
Controlled Variable: no identifiable controlled variable:
Limitations: investigators did not obtain first-hand information as they relied on doctors' reports
The study found that the problem of nosocomial infections is a real challenge in surgical ICU units and such infections occurred at the rate of 11.8%, with pneumonia being the most frequently detected infections followed by urinary tract infections. Thus, the investigators concluded that nosocomial infections increase the morbidity rate of hospitalized patients.The study contains a level III form of evidence
