Background:
Sepsis is frequently associated with hospital readmission. Readmission is a hospital quality measure that reflects dimensions of quality of inpatient care and also impacts overall programs by payors such as CMS’s Star Rating Program, HRRP and Value-Based Purchasing. Levaquin (Levofloxacin) is a prescription medicine used to treat the symptoms of various bacterial infections. Studies have shown that treatment with Levaquin (Levofloxacin) was as effective and well tolerated for patients hospitalized with suspected bacteraemia/sepsis.
Dexur’s analysis of Real-World Evidence based on Medicare Claims data showed that the use of Levaquin (Levofloxacin) within 7 days of hospitalization was associated with lower hospital readmission rates for Sepsis Patients at Wellspan York Hospital in York, Pennsylvania. Reduction in readmission rates helps hospitals improve their outcomes for various cost and quality programs. Dexur is an approved entity to perform Medicare claims data analysis, which it uses to perform quality outcomes analysis. Dexur has published several papers with Harvard Medical School on quality outcomes related topics. Dexur’s analysis of Drugs and their impact on quality outcomes, such as readmissions and mortality, are used by Hospitals, IDNs, and ACOs to implement best practices and manage Real World Evidence based risk factors.
Methods:
We conducted a retrospective study using Dexur’s analysis of Real-World Evidence from Medicare Claims data, for hospitalizations at Wellspan York Hospital between January 2017 to September 2019. Our methodology criteria was as follows:
Results:
Overall, Levaquin (Levofloxacin) was associated with lower hospital readmission rates for all Primary DRG/ICD Diagnosis Codes examined at Wellspan York Hospital. For patients whose primary DRG/ICD Diagnosis was “Sepsis, unspecified organism” (A419) and when Levaquin (Levofloxacin) was used within 7 days of hospitalization, the readmission rate was 22% compared to the cohort where Levaquin (Levofloxacin) was not used, whose readmission rate was 24.24%. The readmission odds ratio for these cohorts was 0.88. The use of Levaquin (Levofloxacin) was associated with a 12% lower readmission rate when used within 7 days of hospitalization. The full list of studied DRG/ICD codes, readmission rates, odds ratios, confidence intervals, and percentage reduction in readmission with Levaquin (Levofloxacin) at Wellspan York Hospital is shown below.

Primary DRG/ICD Diagnosis Code | Primary DRG/ICD Diagnosis Code Description | Total Hospitalizations without Levaquin (Levofloxacin) | Readmission Without Levaquin (Levofloxacin) | Readmission Rate without Levaquin (Levofloxacin) | Total Hospitalizations with Levaquin (Levofloxacin) | Readmission with Levaquin (Levofloxacin) | Readmission Rate with Levaquin (Levofloxacin) | Readmission Odds Ratio | Reduction in Readmission with Levaquin (Levofloxacin) (%) | Confidence Interval (-) | Confidence Intervals (+) |
---|---|---|---|---|---|---|---|---|---|---|---|
A419 | Sepsis, unspecified organism | 2,562 | 621 | 24.24% | 50 | 11 | 22.00% | 0.88 | 12% | -3% | -1% |
871 | Septicemia Or Severe Sepsis Without Mv >96 Hours With Major Complication Or Comorbidity (MCC) |
Dexur also leveraged Medicare claims data to understand what percentage of patients hospitalized with Sepsis were not prescribed Levaquin (Levofloxacin) within 7 days of discharge.
DRG/ICD CODE | Hospital | Hospitalizations with Sepsis | % of Hospitalizations without Levaquin (Levofloxacin) |
---|---|---|---|
A419 | Memorial Hermann Southwest Hospital | 4,555 | 99.50% |
Cedars Sinai Medical Center | 3,361 | 99.55% | |
Wellspan York Hospital | 2,573 | 99.57% | |
871 | Wellspan York Hospital | 2,076 | 99.47% |
Cedars Sinai Medical Center | 3,578 | 99.58% | |
Memorial Hermann Southwest Hospital | 3,812 | 99.69% |
Hospitalizations with Sepsis = Above Listed DRG/ICD Codes
If figures are shared with “At Least” - this implies that the drug utilization within 7 days post hospitalization is less than 11
Conclusions:
According to analysis of Real-World Evidence of Medicare Claims data, for hospitalizations between January January 2017 to September 2019, the use of Levaquin (Levofloxacin) within 7 days of hospitalization can lead to substantial reductions in hospital readmission rates of Sepsis patients at Wellspan York Hospital. This analysis shows that a significant number of Patients are not dispensed Levaquin (Levofloxacin) after Sepsis hospitalizations at Wellspan York Hospital or major US Hospitals.
