RESUMEN
PURPOSE: To determine the effect of influenza vaccination on mortality and hospital readmission rates following discharge of elderly patients admitted with pneumonia. METHODS: We reviewed the medical records of 12,566 randomly selected Medicare beneficiaries hospitalized for pneumonia from October 1 through December 31, 1998, to assess mortality and hospital readmission rates from the date of discharge through the influenza season, May 1, 1999. Patients were grouped based on vaccination status: before hospitalization, during hospitalization, or unknown (no evidence of vaccination). RESULTS: Severity-adjusted mortality rates were 22.4% (95% confidence interval [CI]: 14.4% to 29.7%) for the vaccination before hospitalization group, 26.4% (95% CI: 20.4% to 31.9%) for the in-hospital vaccination group, and 29.4% (95% CI: 28.1% to 30.6%) for the unknown vaccination status group. Patients vaccinated before hospitalization had significantly lower mortality than did patients with unknown vaccination status (hazard ratio [HR] = 0.65; 95% CI: 0.59 to 0.70; P <0.0001). Adjusted readmission rates were 42.6% (95% CI: 40.0% to 45.1%) for the vaccination before hospitalization group, 40.0% (95% CI: 33.2% to 46.1%) for the in-hospital vaccination group, and 44.8% (95% CI: 43.3% to 46.4%) for the unknown vaccination status group. Patients vaccinated before hospitalization had significantly lower readmission rates than patients with unknown vaccination status (HR = 0.92; 95% CI: 0.87 to 0.98; P = 0.009). CONCLUSION: Influenza vaccination before hospitalization was effective in decreasing subsequent mortality and hospital readmission in elderly patients with pneumonia.

BACKGROUND: Despite the publication of guidelines for the management of pneumonia, significant variation in care continues to exist. While there have been several published reports of quality improvement projects for pneumonia, there are few data on the effectiveness of these efforts in small hospitals. The purpose of this study was to demonstrate that a project implemented by a quality improvement organization in small hospitals would lead to an improvement in care that could not be accounted for by secular trends in the management of pneumonia. METHODS: Medicare-insured hospital admissions for pneumonia were reviewed from 20 small hospitals in Oklahoma (intervention group) at baseline and after feedback. Project intervention included onsite feedback presentations to the medical staff, samples of performance improvement materials, and comparative measures of performance of predefined quality indicators. A second group of 16 demographically similar hospitals (control group) was selected for review during the same 2 periods. These hospitals subsequently underwent an identical intervention with a follow-up assessment. RESULTS: Statistically significant improvements in process measures were demonstrated in the intervention hospitals, including performance of a sputum (P<.01) and blood (P<.001) cultures, antibiotic administration within 4 hours of hospital admission (P<.001), and administration of the first dose of antibiotic in the emergency department (P<.001). These measures in the control hospitals did not change significantly (P =.93, .08, .79, and .52, respectively) during the 2 periods. CONCLUSIONS: Improvements in processes of care achieved by the intervention hospitals resulted from activities initiated because of participation in a quality improvement organization-directed project. This study demonstrated the effectiveness of quality improvement activities in very small hospitals.

BACKGROUND: Hospitalized elderly patients are at risk for subsequent influenza and pneumococcal disease. Despite this risk, they are often not vaccinated in this setting. METHODS: We reviewed the medical records of a national sample of 107 311 fee-for-service Medicare patients, 65 years or older, discharged from April 1, 1998, through March 31, 1999, with a principal diagnosis of acute myocardial infarction, heart failure, pneumonia, or stroke. We linked patient identifiers to Medicare Part B claims to identify influenza and pneumococcal vaccines paid for before, during, or after hospitalization. The main outcome measures were documentation by chart review or paid claim of influenza or pneumococcal vaccination. RESULTS: Of the 104 976 patients with a single hospitalization, 35 169 (33.5%; 95% confidence interval [CI], 33.2%-33.8%) received pneumococcal vaccination prior to admission, 444 (0.4%; 95% CI, 0.4%-0.5%) were vaccinated in the hospital, and 1076 (1.0%; 95% CI, 1.0%-1.1%) were vaccinated within 30 days of discharge. In the subgroup of 40 488 patients discharged from October through December, 12 782 (31.6%; 95% CI, 31.1%-32.0%) received influenza vaccination prior to admission, 755 (1.9%; 95% CI, 1.7%-2.0%) were vaccinated in the hospital, and 4302 (10.6%; 95% CI, 10.3%-10.9%) were vaccinated after discharge. Of patients who were unvaccinated prior to admission, 97.3% (95% CI, 97.1%-97.5%) did not receive influenza vaccine and 99.4% (95% CI, 99.3%-99.4%) did not receive pneumococcal vaccine before hospital discharge. CONCLUSION: National recommendations for inpatient vaccination against influenza and pneumococcal disease are not being followed for the vast majority of eligible Medicare patients admitted to the hospital.
