Are labour-intensive efforts to prevent pressure ulcers cost-effective?

BACKGROUND

Pressure ulcers are a major problem in Danish healthcare with a prevalence of 13-43% among hospitalized patients. The associated costs to the Danish Health Care Sector are estimated to be €174.5 million annually. In 2010, The Danish Society for Patient Safety introduced the Pressure Ulcer Bundle (PUB) in order to reduce hospital-acquired pressure ulcers by a minimum of 50% in five hospitals. The PUB consists of evidence-based preventive initiatives implemented by ward staff using the Model for Improvement.

OBJECTIVE

To investigate the cost-effectiveness of labour-intensive efforts to reduce pressure ulcers in the Danish Health Care Sector, comparing the PUB with standard care.

METHODS

A decision analytic model was constructed to assess the costs and consequences of hospital-acquired pressure ulcers during an average hospital admission in Denmark. The model inputs were based on a systematic review of clinical efficacy data combined with local cost and effectiveness data from the Thy-Mors Hospital, Denmark. A probabilistic sensitivity analysis (PSA) was conducted to assess the uncertainty.

RESULTS

Prevention of hospital-acquired pressure ulcers by implementing labour-intensive effects according to the PUB was cost-saving and resulted in an improved effect compared to standard care. The incremental cost of the PUB was -€38.62. The incremental effects were a reduction of 9.3% prevented pressure ulcers and 0.47% prevented deaths. The PSAs confirmed the incremental cost-effectiveness ratio (ICER)'s dominance for both prevented pressure ulcers and saved lives with the PUB.

CONCLUSION

This study shows that labour-intensive efforts to reduce pressure ulcers on hospital wards can be cost-effective and lead to savings in total costs of hospital and social care.

KEY LIMITATIONS

The data included in the study regarding costs and effects of the PUB in Denmark were based on preliminary findings from a pilot study at Thy-Mors Hospital and literature.
