One drug less to prescribe…
Conclusion: Heparin is not necessary in this setting, citrate is an alternative, but saline seems just as good.
In a double-blind placebo-controlled study including a rather small group of critically ill intubated patients they found that aerosolised antibiotics successfully eradicated existing multi-drug resistant organisms and therefore reduced the pressure from systemic agents for new resistance.
While this article is not open access, the editorial by M. Bonten is.
Despite the possibility of some selection bias they conclude that high doses of methylprednisolone are associated with worse outcomes and more frequent adverse effects (like prolonged hospital and ICU length of stay, higher hospital costs, increased length of invasive ventilation, increased need for insulin therapy and higher rate of fungal infections). Mortality itself did not significantly differ.
It is remarkable to note that in this study doses below 240mg of methylprednisolone are considered low-dose. This is equivalent to 300mg of prednisolone and is relatively high for exacerbations of COPD. As we mentioned in a post in November 2013 the REDUCE trial in JAMA compared 5 days to 14 days of steroids in exacerbated COPD. The dosage used there was 40mg of prednisone. The results showed that a 5-day treatment was non-inferior to a 14-day treatment with regard to re-exacerbation within 6 months but significantly reduced glucocorticoid exposure.
In summary it seems to be advisable to use lower doses and short treatment periods in acute exacerbated COPD.
In their article they looked at 14 commonly used local anaesthetics and provide some further background information. The normogram only works with body weights up to 70kg, but they recommend to use the ideal body weight for obese patients. An article worth reading (open access!) and a normogram worth using!
After the 2013 publication by Ghareed et al. (see BIJC post here) on fist bumps in the health care setting in order to prevent transmission of pathogens JAMA now joins in the discussion. Sklansky M et al. published a viewpoint on the banning of the handshake from the health care setting. In their paper they point out that the hands of health care workers often serve as vectors for transmission of organisms and disease. The fact is highlighted that adherence of health care providers with hand hygiene remains rather low and that handshakes have shown to be able to transmit pathogens. In their article they draw parallels between the ban of handshakes in a health care setting and the ban of smoking in public places and finally offer a variety of alternative greetings methods like: the ‘hand wave’ and placement of the right palm over the heart, or the Namaste gesture also practiced in yoga around the world.
This offers an interesting viewpoint worth reading indeed but I might add a few remarks and questions to this article. Apart from the fact that I still struggle to follow the link between hand shakes and smoking in public and would like to highlight following:
– The link between pathogen transmission by handshakes and consecutive patient outcome is totally unclear. At this stage there is no evidence indicating that handshakes themselves impose a serious threat to patients.
– Banning handshakes in hospitals might sound like a good idea, but the main problem remains unaffected. Multi-resistant bacterias are the logical result of inappropriate prescription and usage of antibiotics. It certainly is advisable to prevent the spread of these pathogens but it would be better to prevent their man made evolution.
– Physical contact with patients in the ICU is an essential part in patient care (e.g. nursing or medical examination) and socialising might be even more important when you’re unwell. Of course contact isolation has been found to help prevent the retransmission of pathogens. We tend to forget though that all these measures at the same time might have other unintended consequences. From 1999 to 2003 three articles showed that patients in contact isolation got half as many visits from health care providers resulting in 20% less contact time (Morgan DJ et al. Infect Control Hosp Epidemiol. 2013;34(1):69-73). Remarkably, similar effects were found also a decade later. Evidence has continued to accumulate that patients on contact precautions may experience worse outcomes, including more delirium, more depression, worse discharge instructions, and less smoking cessation counselling.
Withholding a handshake sounds simple but might actually further contribute to patient’s isolation and there is also some research out there actually showing on how important this gesture actually might be (Dolcos S et al. J Cogn Neurosci 2012 Dec;24(12):2292-305).
The first sentence of the Conclusion by Sklansky et al. reads as follows: ‘Banning the handshake from the health care environment may require further study to confirm and better describe the link between handshake-related transmission of pathogens and disease.’… I couldn’t agree more!
I think we might have to be very careful on already starting to talk about ‘hand shake free zones’ as long as there are so many unanswered questions. Many things have been done in the past to prevent infections and finally have been proven to be completely inutile (e.g. changing peripheral lines after three days, read post here). Maybe we she focus more on avoiding overprescribing antibiotics instead.
What do you think…?

Apart form the fact that changing your clothes might be appropriate to do there is this recent article of Hee at al. in Anaesthesia giving you a little chance for forgiveness. Although small in numbers these researches found no evidence that visits to ward or office significantly increase bacterial contamination of scrub suits.
