“…[24][25][26][27] Unlike data from Western high-income countries, 15 publications from low-and middle-income countries in warmer regions of the Earth have reported a higher percentage of SSIs caused by gram-negative pathogens. 28 Although the higher SSI rates in low-and middle-income countries are likely partly attributable to socioeconomic factors, the higher percentage of gram-negative bacteria among SSI causing pathogens indicates that meteorological factors play an important role as well. This interpretation is supported by our data; we not only observed an increase in overall SSI rates but also a shift to gram-negative pathogens that was associated with warmer temperatures.…”

Objective: Surgical site infections (SSIs) occur more frequently during periods of warmer temperatures. We aimed to investigate for which pathogens this association is particularly strong. Design: A retrospective observational study was conducted. Methods: Data from the SSI-module of the German nosocomial infection surveillance system between 2000 and 2016 were linked with data from the German Meteorological Service. Patient- and procedure-related data were associated with monthly aggregated meteorological data. Due to high correlation with other meteorological parameters, we focused on the outside temperature. Adjusted odds ratios were calculated for SSI rates relating to temperature. SSIs were stratified by pathogen. A P value of <.05 was considered significant. Results: Altogether, 2,004,793 procedures resulting in 32,118 SSIs were included. Generally, warmer temperatures were associated with a higher SSI risk, especially for SSIs with gram-negative pathogens. This association was particularly prominent for Acinetobacter spp, Pseudomonas aeruginosa, and certain Enterobacteriaceae. Per additional 1°C, we observed a 6% increase in the SSI risk for Acinetobacter spp and a 4% increase for Enterobacter spp. Superficial SSIs with Acinetobacter spp were 10 times more likely to occur when comparing surgeries in months with mean temperatures of ≥20°C to mean temperatures of <5°C. Conclusions: Higher temperatures were associated with increased SSI rates caused by gram-negative bacteria. Future SSI prevention measures should consider this aspect. Underlying shifts in microbiome composition due to climate factors should be included in further analyses. Given the expected rise of global temperatures until the end of the century, this topic has relevance from multiple perspectives.

“…The infection rates are expectedly higher in low- and middle-income countries that utilise unhygienic OR environment (Allegranzi et al 2016 ; McDonald and Bott 2020 ). Recent statistics show that the total SSI rates for different surgeries are markedly high at 36 % in France (Penel et al 2008 ), 33 % in Vietnam (Viet Hung et al 2016 ), 28 % in Japan (Morikane 2016 ), and 12 % in Malaysia (Wong and Holloway n.d. ). One of the statistics provided by Morikane et al ( 2016 ) shows that the SSI for rectal surgery in Japan is already marked as high as 17.8 %, while in England, the SSI for large bowel surgery, small bowel surgery, and pancreatic surgery are recorded as 8.3 %, 4.9 %, and 4.9 %, respectively (Elgohari et al 2013 ).…”

Graphical abstract In this study, a systematic procedure for establishing the relationship between particulate matter (PM) and microbial counts in four operating rooms (ORs) was developed. The ORs are located in a private hospital on the western coast of Peninsular Malaysia. The objective of developing the systematic procedure is to ensure that the correlation between the PMs and microbial counts are valid. Each of the procedures is conducted based on the ISO, IEST, and NEBB standards. The procedures involved verifying the operating parameters are air change rate, room differential pressure, relative humidity, and air temperature. Upon verifying that the OR parameters are in the recommended operating range, the measurements of the PMs and sampling of the microbes were conducted. The TSI 9510-02 particle counter was used to measure three different sizes of PMs: PM 0.5, PM 5, and PM 10. The MAS-100ECO air sampler was used to quantify the microbial counts. The present study confirms that PM 0.5 does not have an apparent positive correlation with the microbial count. However, the evident correlation of 7% and 15% were identified for both PM 5 and PM 10, respectively. Therefore, it is suggested that frequent monitoring of both PM 5 and PM 10 should be practised in an OR before each surgical procedure. This correlation approach could provide an instantaneous estimation of the microbial counts present in the OR.

Staff practice, driven by knowledge, plays a decisive role in hospital infection control. This study aimed to assess and compare knowledge and self-reported practices of infection control among various occupational groups in a rural and an urban hospital in Vietnam. Questionnaires consisting of items on knowledge and practices were collected from 339 hospital staff with varying occupations. For analysis, total knowledge or practice score ranged from 0–15. Mood’s median test was performed to compare median scores. Post-hoc analysis of ordinal logistic regression models was applied to test differences in scores among occupational groups. The majority of hospital staff had good or adequate knowledge (median score: rural = 11.8; urban = 12), but the score range was wide (1.4–14.5). Self-reported practices in the urban hospital were likely to be better than in the rural one (p = 0.003). Self-reported practices yet not completely satisfactory, indicating the need for continuing professional development in both settings. Overall, cleaners had lower scores than both physicians and nurses, highlighting the need for tailored education in this topic. Future infection control strategies within the hospitals might want to assess the difference between the staff’s self-reported practice and their actual real practice. These findings can be of value in many other similar settings.

Surgical Site Infection Rates in Seven Cities in Vietnam: Findings of the International Nosocomial Infection Control Consortium

Abstract: Our SSIs rates were significantly higher for 11 of the 26 types of SPs than for the CDC-NHSN. This study advances our knowledge of SSI epidemiology in Vietnam and will allow us to introduce targeted interventions.
