Insights
Patients with critical lower limb ischaemia (CLI) experience long delays before specialist review, with many referred non-urgently. This impacts treatment and outcomes, highlighting a need for faster management pathways for CLI.
Area of Science:
- Vascular Surgery
- Patient Management
- Clinical Outcomes
Background:
- Critical lower limb ischaemia (CLI) presents a significant challenge in vascular care.
- Timely diagnosis and intervention are crucial for limb salvage and patient survival.
Purpose of the Study:
- To evaluate the management pathway for patients with critical lower limb ischaemia (CLI) from initial presentation through to investigation and treatment.
- To identify delays and assess referral patterns in CLI patient care.
Main Methods:
- A prospective study involving patients presenting with critical lower limb ischaemia.
- Data collected over a one-year period (May 2000-May 2001) with follow-up ranging from 3 to 15 months.
Main Results:
- 134 CLI patients were analyzed; 49% male, 30% diabetic, median age 81. Most were referred non-urgently, with a median wait of 25 days for outpatient review.
- Treatment included conservative management (70), major amputations (17), and revascularization procedures (62).
- At follow-up, major amputation and death rates were 12% and 27%, respectively. Diabetics had higher amputation rates, and those with ulceration/gangrene faced increased mortality risk.
Conclusions:
- Patients with CLI often experience prolonged symptom duration before specialist assessment, with a high proportion referred as non-urgent.
- The current management pathway for CLI contrasts sharply with urgent referral standards for suspected malignancies, indicating potential system inefficiencies.
- There is a critical need to improve the speed and urgency of specialist assessment for CLI patients to improve outcomes.
Objectives:
to determine management of patients with critical lower limb ischaemia (CLI) from first presentation to investigation and treatment.
Design:
prospective study of critical ischaemia patients.
Methods:
one-year prospective survey (May 2000-May 2001). Follow-up 3-15 months.
Results:
some 873 arterial cases presented, 134 patients had CLI. Of the latter 49% were men, 30% diabetic, the median age was 81 years. Only 15 (24%) of 62 cases were referred to outpatients as urgent. Patients waited a median of 25 days (range 1-100) to be seen in outpatients, and had symptoms for a median of 8 weeks. Treatment was conservative for 70 patients, and 11 primary amputations, six secondary amputations, and 62 revascularisation procedures (34 operative, 28 percutaneous transluminal angioplasty) were performed. At follow-up (3-15 months, median 9 months), rates of major amputation and death were 12 and 27% respectively. Significantly more diabetics underwent major amputation (p < 0.02) than non diabetics. Patients presenting with ulceration or gangrene were at greater risk of death than those with rest pain alone (p < 0.01).
Conclusion:
patients with CLI often have symptoms for many weeks before being seen by a specialist, and 76% are referred as non-urgent cases. This compares with patients with suspected malignant disease in the U.K. who are required to be seen within 2 weeks.
