A realist evaluation to identify targets to improve the organization of compression therapy for deep venous thrombosis- and chronic venous disease patients

Graduated elastic compression stockings in the prevention of post-thrombotic syndrome: A systematic review and meta-analysis

BACKGROUND

The effect of graduated elastic compression stockings (ECS) in the prevention of post-thrombotic syndrome (PTS) has been questioned since a large randomized trial found no prophylactic effect of ECS.

OBJECTIVE

To assess the effect of the wearing time of ECS on the incidence of post-thrombotic syndrome (PTS) after proximal deep venous thrombosis, we performed a meta-analysis of the incidence of PTS across randomized and observational studies.

METHOD

PubMed, Embase and Cochrane databases were searched until 12 June 2023 for studies on the effect of ECS on PTS. References of eligible studies were also screened in order to identify other potential studies that might have been missed during the search.

RESULTS

Four studies comprising a total of 1467 patients met our inclusion criteria for early initiation and consistent use of ECS in patients with acute proximal DVT. ECS significantly reduced the incidence of mild-moderate PTS (OR: 0.48; 95% CI: 0.36-0.63) as well as severe PTS (OR: 0.44; 95% CI: 0.28-0.58).

Budget Impact of Three Improvement Targets for Compression Therapy for Patients with Deep Venous Thrombosis in The Netherlands

BACKGROUND AND OBJECTIVE

Compression therapy following deep venous thrombosis in the Netherlands is suboptimal. We assessed the budget impact of targeted care improvements.

METHODS

We calculated the per-patient and population healthcare resource use and costs concerning 26,500 new patients each year in the Netherlands for the current pathways in region North Holland (divided into two parts: NH-A and NH-B) and region Limburg. Next, we assessed the impact of three improvement targets: optimizing initial compression therapy, early consultation of an occupational therapist, and tailored duration of elastic compression stocking therapy. Inputs were based on interview (n = 30) and survey data (n = 114), literature, and standard prices. The robustness of the results was tested by sensitivity analyses.

RESULTS

The current per-patient costs for a 2-year episode were €1046 (NH-A), €947 (NH-B), and €1256 (Limburg). The improvements led to direct savings for region Limburg (€4.7 million). Population costs increased in the first year for NH-A (+ €3.5 million) and NH-B (+ €6.4 million), and decreased in the second and third year resulting in a cost reduction for NH-A (- €2.2 million) but not for NH-B (+ €0.6 million). Workload for occupational therapists and internists in North Holland increased, and workload for home care nurses decreased in all regions.

CONCLUSIONS

This study provides a detailed insight into current costs and healthcare resource use associated with compression therapy and the potential impact of implementing three improvement targets. We showed that the improvements resulted in considerable cost savings within 3 years after implementation for region NH-A and Limburg.
