Domiciliary non-invasive ventilation for recurrent acidotic exacerbations of COPD: an economic analysis1
Tuggey JM, Plant PK, Elliott MW
Patients with chronic obstructive pulmonary disease (COPD) tend to have frequent exacerbations necessitating hospital admission. Each admission has been estimated to cost £3000. The requirement for intensive care significantly increases this cost.
This study looked at the potential for cost savings in a carefully selected group of patients with severe COPD with recurrent admissions due to respiratory acidosis.
The primary outcome was total hospital costs incurred per patient per year. Effectiveness outcomes were total days in hospital and in intensive care.
Thirteen patients who had previously tolerated noninvasive ventilation (NIV) well in the hospital setting were offered domiciliary NIV.
Provision of a home NIV service resulted in a mean (95% CI) saving of £8254. Total days in hospital fell from a mean of 78 to 25 (p=0.004), number of admissions from five to two (p=0.007), and ICU days fell from a total of 25 to four (p=0.24). Outpatient visits fell from a mean of 5) to 4 (p=0.14).
Cost data per year (n=13) for patients using home NIV vs. patients without home NIV. *Other costs include respiratory nurse, training and outpatient appointments. Adapted from Tuggey et al.
