Variation in resource utilization and mortality among patients with varying mitral regurgitation (MR) type and severity
Authors' conclusion
Resource utilization and outcomes vary by MR type and severity. Utilization of resources, such as TTE, during guideline-recommended surveillance periods was not associated with a reduction in mortality while other care (catheterization or surgery) was associated with improved survival.
Study context
- Population
- Patients with moderate or severe MR on index echo, Duke Echocardiography Laboratory Database, 2000–201684.7% moderate MR
- Participants
- 4,511 patients
- Exposure
- Resource utilization and outcomes across MR type and severity
- Outcome
- Cumulative resource utilization (TTE, TEE, cardiac catheterization, cardiology/CTS referral, MV surgery/TEER, hospitalizations) by MR severity and type; 5-year mortality
- Follow-up
- 5 years
Methodological detailssingle-centre echocardiography database, multivariable landmark analysis
- Single-centre echocardiography database
- Multivariable landmark analysis
Main finding
As reported in the abstract
Resource utilization
- Mean 5-year cumulative resource utilization rate (encounters/patient)
- 11.1
- Significant variation in utilization of each resource by MR type
- all P < .05
Observational data: associations, not effects.
Further findings
5-year mortality by resource use during landmark period (6 to 12 months)
- Moderate MR: CTS referral associated with significantly lower mortality
- P < 0.05
- Severe MR: cardiac catheterization or MV surgery associated with significantly lower mortality
5-year hospitalization costs by MR type
- Secondary ischemic and non-ischemic MR had significantly higher costs vs primary myxomatous MR
- P < 0.05
