Impact of UK NICE Clinical Guidelines 168 and social deprivation on access to interventional treatment for symptomatic varicose vein and specialist referral for leg ulceration

OUP accepted manuscript

Background

Varicose vein (VV) treatments have changed significantly in recent years leading to potential disparities in service provision. The aim of this study was to examine the trends in VV treatment in England and to identify disparities in the provision of day-case and inpatient treatments related to deprivation, ethnicity, and other demographic, and geographical factors.

Method

A population-based study using linked hospital episode statistics for England categorized VV procedures and compared population rates and procedure characteristics by ethnicity, deprivation quintile, and geographical area.

Results

A total of 311 936 people had 389 592 VV procedures between 2006/07 and 2017/18, with a further 63 276 procedures between 2018/19 and 2020/21. Procedure rates have reduced in all but the oldest age groups, whereas endovenous procedures have risen to more than 60 per cent of the total in recent years. In younger age groups there was a 20–30 per cent reduction in procedure rates for the least-deprived compared with the most-deprived quintiles. Non-white ethnicity was associated with lower procedure rates. Large regional and local differences were identified in standardized rates of VV procedures. In the most recent 5-year interval, the North-East region had a three-fold higher rate than the South-East region with evidence of greater variation between commissioners in overall rates, the proportion of endovenous procedures, and policies regarding bilateral treatments.

Conclusions

There are substantial geographical variations in the provision of treatment for VVs, which are not explained by demographic differences. These have persisted, despite the publication of guidelines from the National Institute for Health and Care Excellence, and many commissioners, and providers would seem to implement policies that are contrary to this guidance. Lower rates of procedures in less-deprived areas may reflect treatments carried out in private practice, which are not included in these data.

A systematic review of community Leg Clubs for patients with chronic leg ulcers

Aim

Appraise the evidence on the outcomes of Leg Clubs on ulcer healing, psychosocial outcomes, patient safety, cost and experiences of Leg Club members.

Background

The Leg Club is a community-based social model of care in 30 UK locations and nine overseas for treating patients with chronic leg wounds. However, its cumulative effectiveness has not been reviewed to-date.

Methods

Systematic review of primary research relating to the impact and quality of care of Leg Clubs treating patients with leg ulcers. Six electronic databases were systematically searched using the MeSH term ‘leg ulcer’, including other representative terms, in combination with ‘Leg Club’. The quality of individual studies was assessed using appraisal tools. The confidence in the quantitative evidence was evaluated using Grading of Recommendations Assessment, Development and Evaluation (GRADE); and the Confidence in the Evidence from Reviews of Qualitative Research (CERQual) assessed the quality of qualitative findings.

Findings

A total of 17 relevant publications were identified. Out of the 17 articles, four publications represent findings from randomised controlled trial (RCT). Thus, evidence from 14 independent studies involving at least 532 participants were included in the synthesis of this review. The quality of the evidence varied across the different outcomes and were mostly low or of very low quality. Findings from one underpowered RCT from Australia reporting on clinical, patient-reported outcomes and economic outcomes were evaluated as moderate quality. Studies indicate that the Leg Club model has a positive impact on ulcer healing and recurrence, mood, sleep, quality of life and pain. Moreover, only three studies assessed wound infections and reported no infections had occurred during treatment at the Leg Clubs. Economic evaluations find Leg Clubs to be probably more cost-effective than usual care. Both patients and nurses projected positive views about the Leg Clubs, with particular emphasis on improved social interactions and delivery of patient-centred care.
