Observation and inpatient status: clinical impact of the 2-midnight rule

hospital bed

Dr. Ann Sheehy et al. recently published a study in the Journal of Hospital Medicine on the clinical impact of the CMS rule that classifies most hospital encounters of less than 2 midnights as observation and 2 midnights or greater as inpatient. They found that applying the rule predicted a net loss of nearly 15% inpatient stays. Only 1 of the 5 top ICD-9 codes was the same for inpatient and observation stays that were less than 2 midnights, and observation encounters that started before 8:00 am spanned 2 midnights less frequently than encounters that started later in the day. Today's Hospitalist recently published an article about the study

Rehospitalization to primary versus different facilities following abdominal aortic aneurysm repair

HospitalIn a study to characterize readmissions to primary vs. different hospitals after open or endovascular abdominal aortic aneurysm repair, Dr. Scott Saunders et al. found that 13.1% of patients were readmitted within 30 days.  Among those patients, 70.7% returned to the same facility as their primary admission, while 29.3% returned to a different facility. The strongest predictor of readmission to a different facility was greater distance from the patient's residence to the primary hospital. Read more

Female ptDr. Elizabeth Jacobs et al. analyzed data from over 3,000 women participating in the Study of Women's Health Across the Nation (SWAN) and found that racial discrimination was perceived by 35% of African American women, 20% of Chinese women, 12% of Hispanic women, 11% of Japanese women, and 3% of non-Hispanic white women.
