Hip replacement and hip hemiarthroplasty surgery: potential opportunities to shorten lengths of hospital stay.

The potential safety and effectiveness of a practice guideline recommending a 5-day postoperative stay in the acute care hospital for hip surgery patients without clinical findings predictive of a complicated hospital course was studied retrospectively in 230 patients hospitalized for total hip replacement, total hip replacement with osteotomy, or hip hemiarthroplasty. Seventy percent of total hip replacement and hip hemiarthroplasty patients were classified as being at "low risk" for complications by the guideline (161 patients, or 73% of patients who remained hospitalized). Use of the guideline could have reduced the hospital length of stay from 8.4 days (standard deviation 3.3) to 5.9 days for these selected low-risk patients. Moreover, physicians' implicit review determined that 0% of patients (95% confidence interval, 0% to 2.3%) had a complication that would have benefited from continued stay in an acute care hospital after the fifth postoperative day. Our practice guideline may have the potential to safely reduce acute care hospital length of stay for patients recovering after total hip replacement and hip hemiarthroplasty. The guideline will require further study in a prospective clinical trial before it can be recommended for widespread use.

Identification of low-risk hospitalized patients with pneumonia. Implications for early conversion to oral antimicrobial therapy.

PURPOSE: Few available data exist to define either the medically necessary duration of parenteral antimicrobial therapy or length of stay for hospitalized patients with pneumonia. Therefore, we investigated the potential safety and effectiveness of a practice guideline recommending early conversion of low-risk patients with pneumonia from parenteral to oral antimicrobial therapy and early hospital discharge. PATIENTS AND METHODS: The practice guideline was studied retrospectively in 503 hospitalized patients with pneumonia at a teaching community hospital. RESULTS: Thirty-three percent of patients with pneumonia were classified as at low risk for complications and potentially suitable for early conversion to oral antimicrobial therapy according to the guideline. Were the guideline to have been used to guide patient discharge decisions, 619 additional bed-days would have been made available to accommodate incoming patients. A consensus among physician reviewers led to the judgment that quality of care would not have worsened for 98.2 percent of low-risk patients had they been switched to oral antimicrobial therapy on the third hospital day, nor would quality of care have been worsened for 93.4 percent of low-risk patients had they been discharged on the fourth hospital day. CONCLUSION: The practice guideline that we studied has the potential to safely reduce the duration of parenteral antimicrobial therapy and length of hospital stay for selected low-risk patients with pneumonia. The guideline should be studied in a prospective clinical trial.
