V.A.C.® Therapy Cost-Effectiveness

V.A.C. Therapy cuts treatment costs by a third1

In Apelqvist's economic analysis1 of the Armstrong diabetic foot wound RCT, V.A.C. Therapy was shown to lower costs dramatically compared to AMWT* for patients treated for ≥ 8 weeks. Specific V.A.C. Therapy cost-effectiveness data demonstrated:

Reduced Average Direct Cost Independent of Outcome
Lower Average Total Cost to Achieve Healing
Lower Average Weekly Total Cost
Fewer Surgical Procedures
Fewer Outpatient Visits
Fewer Dressing Changes
Less Days of Therapy

Reduced Average Direct Cost Independent of Outcome1

Reduced Average Direct Cost Independent of Outcome
Average direct treatment cost per patient treated for 8 weeks or longer, independent of outcomes.

The V.A.C. Therapy group average direct cost for patients treated for ≥ 8 weeks was almost $9,000 less per patient than that of the AMWT* group.

*Highest costs were related to in-hospital stay, antibiotics and wound dressing treatment needed.

V.A.C. Therapy cuts total treatment costs by a third1

Lower Average Total Cost to Achieve Healing
Average total cost to achieve 100% healing. Patients treated for 8 weeks or longer.

The V.A.C. Therapy group average total cost to achieve healing was $12,852 less per patient than the AMWT group.

  • Post amputation wounds receiving V.A.C. Therapy obtained wound healing at a lower overall cost of care compared to AMWT.
  • V.A.C. Therapy patients required substantially less resources to heal their wounds than the AMWT group.

Lower Average Weekly Total Cost1

Lower Average Weekly Total Cost
Average weekly total cost among patients fulfilling 8 weeks of treatment.

Among patients fulfilling 8 weeks of treatment, the average weekly total cost for V.A.C. Therapy was over $1,500 less than AMWT ($3,338 vs. $4,853).

Fewer Surgical Procedures1

Fewer Surgical Procedures

For patients treated for 8 weeks or more, a decreased number of surgical procedures in the V.A.C. Therapy group contributed to the lower overall cost of care when compared to AMWT.*

Fewer Outpatient Visits1

Fewer Outpatient Visits
Patients treated for 8 weeks or longer.

Patients treated with V.A.C. Therapy for their diabetic foot wounds experienced significantly less outpatient clinic visits per subject than the AMWT group (p<0.05).

Fewer Dressing Changes1

Fewer Dressing Changes

The average number of dressing changes per patient was 65% less for V.A.C. Therapy patients: 42 V.A.C. Therapy vs. 118 AMWT; p <.001.

Less Days of Therapy1

Less Days of Therapy

Of the 1,189 inpatient therapy days, subjects treated with V.A.C. Therapy (n=25) had less days of wound therapy relative to those treated with AMWT (n=22): 46% vs. 54%, respectively.

AMWT = Advanced Moist Wound Therapy (hydrogels, alginates, collagen and hydrocolloids).
