Contemporary global perspectives of medical students on research during undergraduate medical education: a systematic literature review

BACKGROUND

The need for increased expertise in evidence-based medicine and concerns about the decreasing numbers of physician-scientists have underscored the need for promoting and encouraging research in medical education. The critical shortage of physician-scientists has assumed a dimension demanding a coordinated global response. This systematic review examined the perceptions of medical students regarding research during undergraduate medical school from a global perspective.

METHODS

Articles for this review were searched using PubMed, SCOPUS and Cochrane. Studies published within the last 10 years of the start date of the study that met specified criteria were included. Identified articles were initially screened by title as well as keywords and their abstracts were further screened to determine relevance. Full-text of screened articles were read for validation prior to inclusion.

RESULTS

A total of 26 articles from the literature met the set criteria for final inclusion. Contents of the abstracts and corresponding full-text articles were analyzed for themes on the research perspectives of medical students. The themes derived comprised: research interest, physician-scientist decline and shortage, responses to physician-scientist shortage, curriculum issues, skills (motivation and self-efficacy), research needs, socioeconomic and cultural issues, and barriers.

CONCLUSION

Despite the wide variations in medical education systems worldwide, the perspectives of medical students on research in undergraduate medical education shared many common themes. Globally, medical students underscored the necessity and importance of research in medical education as reflected by many students reporting positive attitudes and interest in research endeavors. Moreover, a worldwide consensus emerged regarding the decline in the numbers of physician-scientists and the necessity for a reversal of that trend. Various barriers to research engagement and participation were highlighted.

Clinical risk factors for methicillin-resistant Staphylococcus aureus bacteriuria in a skilled-care nursing home

OBJECTIVE

To establish the risk factors for methicillin-resistant Staphylococcus aureus (MRSA) bacteriuria in a nursing home population.

DESIGN, SETTING, AND SUBJECTS

A case-control study was conducted in a 360-bed skilled-care nursing facility in the northeastern United States that was experiencing an outbreak of MRSA. Fifteen residents were identified as having had MRSA isolated from their urine over an 18-month period and were compared with 40 controls who were randomly selected from all nursing facility residents.

RESULTS

In bivariate analysis, MRSA bacteriuria was associated with the presence of an indwelling urinary catheter (odds ratio [OR], 36; 95% confidence interval [CI], 7.0 to 184.2), antibiotic use in the prior 6 months (OR, 2.9; 95% CI, 1.5 to 5.5), and impaired physical function (OR, 5.8; 95% CI, 1.3 to 26.6). Urinary catheter use and antibiotic use remained significantly associated with MRSA bacteriuria even when controlling for impaired physical function.

CONCLUSIONS

Methicillin-resistant S aureus is being isolated with increasing frequency in nursing homes, and MRSA bacteriuria may prove to be an important reservoir for the spread of organisms in long-term-care settings. Conservative use of indwelling urinary catheters and of broad-spectrum antibiotics should be investigated as potential control measures to reduce the spread of MRSA in nursing homes.
