Scores that evaluate newborn intensive care units are inconsistent

A new study published in Pediatrics found that scoring methods for evaluating Newborn Intensive Care Units (NICU) are inconsistent, leading to unreliable comparisons. The research suggests that these scores may not level the playing field well enough and can be unfair to hospitals with high numbers of sick infants.

'Very low' risk of infections in advanced brain procedures

A study published in Neurosurgery found that patients undergoing cerebral angiography and neurointerventional procedures are at a very low risk of infection, even without preventive antibiotics. The authors suggest that the minimally invasive nature and short duration of these procedures may contribute to this low risk.
