Physician perspectives of Helicobacter pylori diagnostic and treatment practices in Canada: results of a Canadian survey.

BACKGROUND: Helicobacter pylori infection is prevalent worldwide and can lead to peptic ulcer disease (PUD) and gastric cancer. Effective diagnosis and treatment of H. pylori infection by gastroenterologists and family physicians is crucial. However, there are differing views on optimal diagnosis and treatment. The objective of this study is to understand the impressions of Canadian physicians regarding H. pylori diagnosis and treatment and whether impressions differ between gastroenterologists and family physicians. A second objective is to understand physician perspectives on rising antibiotic resistance and how that guides empiric management. METHODS: A survey facilitated via REDCap was administered to Canadian gastroenterologists and family physicians. A total of 105 participants completed the survey, including 43 gastroenterologists and 62 family physicians. Gastroenterologists were recruited from across the country and family physicians were recruited from Manitoba. RESULTS: For diagnosis of H. pylori, 67% of gastroenterologists reported endoscopic biopsies for histology assessment as most common and 73% of family physicians reported serology as their main diagnostic test. While nearly all gastroenterologists believed antibiotic resistance to be a problem, nearly one quarter of family physicians did not believe it was a problem. CONCLUSIONS: There is variability in practices among both gastroenterologists and family physicians regarding diagnosis of H. pylori infection. There was consensus that local antibiotic resistance patterns should guide management. If known, the degree and patterns of antibiotic resistance could bring a more uniform consensus to H. pylori management. Greater education of physicians, especially family physicians regarding management of H pylori is needed.

Assessment of cleaning methods on bacterial burden of hospital privacy curtains: a pilot randomized controlled trial.

Healthcare-associated infections (HAIs) are an important global issue, leading to poor patient outcomes. A potential route of transmission of HAIs is through contact with hospital privacy curtains. The aim of this study is to evaluate cleaning on reduction of curtain bacterial burden. In this pilot cluster randomized controlled trial we compared the bacterial burden between three groups of 24 curtains on a regional burn/plastic surgery ward. A control group was not cleaned. Two groups were cleaned at 3-4 day intervals with either disinfectant spray or wipe. The primary outcome was the difference in mean CFU/cm2 between day 0 to day 21. The secondary outcome was the proportion of curtains contaminated with Methicillin-resistant Staphylococcus aureus (MRSA). By day 21, the control group was statistically higher (2.2 CFU/cm2) than spray (1.3 CFU/cm2) or wipe (1.5 CFU/cm2) (p < 0.05). After each cleaning at 3-4 day intervals, the bacterial burden on the curtains reduced to near day 0 levels; however, the level increased again over the intervening 3-4 days. By day 21, 64% of control curtains were contaminated with MRSA compared to 10% (spray) and 5% (wipe) (p < 0.05). This study show that curtains start clean and progressively become contaminated with bacteria. Regularly cleaning curtains with disinfectant spray or wipes reduces bacterial burden and MRSA contamination.

Influence of musical background on surgical skills acquisition.

BACKGROUND: There is growing interest in identifying trainees with surgical aptitude predictive of eventual technical proficiency. Musical tasks involve complex, cerebral activity, and ambidextrousity, which may have a positive impact on the acquisition of surgical skill sets. The purpose of this study was to investigate the influence of prior musical experience on the performance of basic surgical skills. METHODS: This was a prospective cross-sectional study involving 51 novice undergraduate and medical school trainees with no prior surgical exposure. Musicality was assessed with a detailed survey and objectively with the Mini-Profile of Music Perception Skills test. Dexterity was assessed using the Purdue Pegboard test. Surgical skills were then evaluated by performing 2 timed suturing trials after observing tutorial video, followed by a timed laparoscopic peg transfer test. Outcomes included both speed and quality of performance. RESULTS: Participants with prior musical experience performed better than nonmusicians on the Mini-Profile of Music Perception Skills test (P = .015), dominant hand dexterity (P = .05), suture quality (P < .03), and laparoscopic peg transfer speed (P < .01). There was no significant difference in the suturing speed between musicians and nonmusicians. The dexterity and Mini-Profile of Music Perception Skills scores were predictive of suture quality (P < .01). Among musicians, duration of musical training, inactivity, instrument type, and certification levels did not correlate with differences in surgical task performance. CONCLUSION: Musical background is associated with better performance of fundamental surgical skills among surgical novices, particularly technique quality. Although this does not imply superior ultimate surgical ability, musicality may be a marker for basic surgical skill development useful in identifying suitable candidates for surgical training.
