The Effect of Participation in Tier 3 Services on the Uptake of Bariatric Surgery.

BACKGROUND: Despite the recognised advantages of bariatric and metabolic surgery, only a small proportion of patients receive this intervention. In the UK, weight management systems are divided into four tiers. Tier 3 is a clinician-lead weight loss service while tier 4 considers surgery. While there is little evidence that tier 3 has any long-term benefits for weight loss, this study aims to determine whether tier 3 improves the uptake of surgery. METHOD: A retrospective cohort study of all referrals to our unit between 2013 and 2016 was categorised according to source-tier 3, directly from the general practitioner (GP) or from another speciality. The likelihood of surgery was calculated using a regression model after considering patient demographics, comorbidities and distance from our hospital. RESULTS: Of the 399 patients, 69.2% were referred directly from the GP, 21.3% from tier 3, and 9.5% from another speciality of which 69.4%, 56.2%, and 36.8% progressed to surgery (p = 0.01). On regression analysis, patients from another speciality or GP were more likely to decide against surgery (OR 2.44 CI 1.13-6.80 p = 0.03 and OR 1.65 CI 1.10-3.12 p = 0.04 respectively) and more likely to be deemed not suitable for surgery by the MDT (OR 6.42 CI 1.25-33.1 p = 0.02 and OR 3.47 CI 1.11-12.9 p = 0.03) compared with tier 3 referrals. CONCLUSION: As patients from tier 3 were more likely to undergo bariatric and metabolic surgery, this intervention remains a relevant step in the pathway. Such patients are likely to be better informed about the benefits of surgery and risks of severe obesity.

Hand compartment syndrome as a result of intravenous contrast extravasation.

Hand compartment syndrome is a rare condition which can result from crush injuries, fractures, burns, intravenous fluid extravasation, etc. Failing to recognize and treat it early leads to significant functional deficits of the hand. Few cases of iatrogenic hand compartment syndrome have been described in the literature so far. We present a case of a hand intravenous (IV) contrast medium extravasation injury in a 72-year-old female patient, during a CT scan. As soon as the swelling of the hand was noticed, elevation of the limb was suggested and ice was applied. Few hours later though the patient developed compartment syndrome of the hand with paresthesias and severe pain with passive movement of the fingers. Left hand emergent fasciotomies were performed leading to a good functional outcome.
