There are a number of potential factors that may contribute to the higher probability of dying in the hospital on weekends. One factor is that hospitals often have fewer resources available on weekends, including both staff and equipment. This can lead to longer wait times for patients, as well as less experienced or specialized care, leading to poorer outcomes overall. In addition, weekend admissions may also be more likely to include emergency cases which tend to be more serious and often require more intensive treatments than non-emergency cases. Finally, weekend admissions may also be subject to limited access due to transportation difficulty or lack of personnel or other resources needed for admission outside regular business hours.
