Insights
Chronic obstructive pulmonary disease (COPD) significantly increases mortality and complications in elderly men with hip fractures. Addressing modifiable risk factors like smoking and anesthesia type can improve outcomes for these vulnerable patients.
Area of Science:
- Geriatric Medicine
- Pulmonology
- Surgical Outcomes Research
Background:
- Hip fractures in the elderly are associated with high mortality and perioperative complications.
- Both male gender and chronic obstructive pulmonary disease (COPD) are linked to worse outcomes, potentially due to increased comorbidities.
Purpose of the Study:
- To assess the association of COPD with mortality and complications in a large cohort of male veterans undergoing hip fracture surgery.
- To identify modifiable risk factors and opportunities for improving outcomes in COPD patients with hip fractures.
Main Methods:
- Utilized the VA Surgical Quality Improvement Program (VASQIP) and administrative databases for a cohort of 12,646 male veterans (1998-2005).
- Determined COPD status (severe vs. mild), comorbidities, and surgical factors.
- Compared outcomes including surgical complications, 30-day, and one-year mortality.
Main Results:
- COPD was present in 47% of patients; severe COPD in 26% and mild in 21%.
- One-year mortality was 40.2% for severe COPD, 31.0% for mild COPD, and 28.8% for non-COPD patients.
- Significant modifiable risk factors included current smoking, general anesthesia, and surgical delays. Osteoporosis was identified pre-fracture in only 3% of subjects.
Conclusions:
- COPD is highly prevalent in male veterans with hip fractures and independently associated with increased mortality and complications.
- Regional anesthesia and urgent surgical scheduling may improve outcomes for COPD patients.
- Underdiagnosis of osteoporosis in COPD patients highlights a need for improved screening and management to reduce hip fracture incidence.
Unlabelled:
Hip fractures in the elderly have high rates of mortality and perioperative complications. Both men and COPD patients have worse mortality and complications but this may be due to more co-morbid disease. We assessed mortality and complications in a large cohort (n = 12,646) of men undergoing hip fracture surgery within the Veteran's Health Affairs (VHA) to define the association of COPD to these outcomes after adjusting for other key factors. We looked for opportunities to improve outcomes for COPD patients.
Methods:
Using the VA Surgical Quality Improvement Program (VASQIP), and administrative databases, we determined COPD status, types of co-morbid conditions and surgical factors, and compared these to outcomes of surgical complications, 30-day and one-year mortality for patients who underwent hip fracture repair during 1998 to 2005.
Results:
COPD was noted in 47% of the hip fracture patients studied. In 3,261 (26%) cases, the COPD was "severe: (indicated by functional disability, previous hospitalization for exacerbation, chronic drug treatment or record of FEV(1) <75% predicted), and in 2,736 (21%) cases it was considered "mild" (any previous outpatient visit or hospitalization with a coded diagnosis of COPD). Severe COPD patients had one year mortality of 40.2% compared to 31.0% in mild COPD and 28.8% in non-COPD subjects. Current smoking, use of general anesthesia and delays to surgery were significant modifiable risk factors identified in adjusted models. Osteoporosis was known pre-fracture in only 3% of subjects.
Conclusions:
COPD was very common in male veterans with hip fractures and was associated with increased risk of death and complications. Increased use of regional anesthesia and urgent scheduling of hip fracture surgery may improve outcomes for patients with COPD. Osteoporosis was rarely identified preoperatively. Improving diagnosis and treatment of osteoporosis in COPD patients could reduce the incidence of hip fractures.
