PURPOSE: To determine whether observing patients overnight in the hospital after intravenous antibiotics have been discontinued is a useful way to identify important clinical events.
SUBJECTS AND METHODS: We performed a retrospective chart review of patients admitted during a 6-month period to a tertiary care teaching hospital with a primary diagnosis of either pneumonia, urinary tract infection, or cellulitis who were treated with intravenous antibiotics. Charts were abstracted for patient characteristics, including comorbid illnesses and laboratory values, as well as for evidence of recurrent infection or other adverse events.
RESULTS: Of the 374 patients in the study, 63 (17%) were discharged on the day intravenous antibiotics were discontinued. These patients were 10 years younger (P = 0.0009) and had fewer comorbid illnesses (P = 0.02) than those who were observed in the hospital. Recurrent infection was noted in 3 (1%; 95% confidence interval 0.2% to 3%) of the 308 patients who were observed. A mild adverse antibiotic reaction was also noted in three observed patients. The readmission rate to the same institution for recurrent infection was 3% for patients with an observation period and 2% for patients without an observation period (P = 0.70).
CONCLUSIONS: Observing patients overnight in the hospital after discontinuing intravenous antibiotics is a common clinical practice. There was an extremely low incidence of adverse events during the observation period, and the events that did occur would have been discovered in an outpatient setting. In-hospital observation after discontinuing intravenous antibiotics is unnecessary for most patients with pneumonia, urinary tract infection, or cellulitis and greatly increases health-care costs.

PURPOSE: To evaluate the clinical benefit of in-hospital observation after the switch from intravenous (IV) to oral antibiotics in a large Medicare population. Retrospective studies of relatively small size indicate that the practice of in-hospital observation after the switch from IV to oral antibiotics for patients hospitalized with community-acquired pneumonia (CAP) is unnecessary.
METHODS: We performed a retrospective examination of the US Medicare National Pneumonia Project database. Eligible patients were discharged with an ICD-9-CM diagnosis consistent with community-acquired pneumonia and divided into 2 groups: 1) a "not observed" cohort, in which patients were discharged on the same day as the switch from IV to oral antibiotics and 2) an "observed for 1 day" cohort, in which patients remained hospitalized for 1 day after the switch from IV to oral antibiotics. We compared clinical outcomes between these 2 cohorts.
RESULTS: A total of 39,242 cases were sampled, representing 4341 hospitals in all 50 states and the District of Columbia. There were 5248 elderly patients who fulfilled eligibility criteria involving a length of stay of no more than 7 hospital days (2536 "not observed" and 2712 "observed for 1 day" patients). Mean length of stay was 3.8 days for the "not observed" cohort and 4.5 days for the "observed for 1 day" cohort (P<.0001). There was no significant difference in 14-day hospital readmission rate (7.8% in the "not observed" cohort vs 7.2% "observed for 1 day" cohort, odds ratio 0.91; 95% confidence interval [CI]0.74-1.12; P =.367) and 30-day mortality rate (5.1% "not observed" cohort vs 4.4% in the "observed for 1 day" cohort, odds ratio 0.86; 95% CI, 0.67-1.11; P =.258) between the "not observed" and "observed for 1 day" cohorts.
CONCLUSIONS: Our analysis of the US Medicare Pneumonia Project database provides further evidence that the routine practice of in-hospital observation after the switch from IV to oral antibiotics for patients with CAP may be avoided in patients who are clinically stable although these findings should be verified in a large randomized controlled trial.
