The Legs For Life Screening for Peripheral Vascular Disease: results of a prospective study designed to improve patient compliance with physician recommendations.
PURPOSE: To determine how compliance with recommendations made by physicians during the 2000 Legs For Life National Screening for Peripheral Vascular Disease (PVD) and Leg Pain is affected through the use of (i) simple and concise patient information and recommendation cards and (ii) a "targeted" postscreening follow-up plan. MATERIALS AND METHODS: Patients were initially screened for PVD by completion of the Legs For Life Risk Factor Assessment form and determination of bilateral ankle/brachial indexes (ABIs). Each patient then met with an interventional radiologist or vascular surgeon. Patients with normal ABIs (>1.0 bilaterally) or mildly abnormal ABIs (<1.0 but >0.90) were classified as having no risk and low risk, respectively. Patients with ABIs of 0.70-0.89 were classified as having moderate risk for PVD and patients with ABIs <0.69 were classified as having high risk for PVD. Physicians reviewed the Risk Factor Assessment form with each patient and made specific lifestyle improvement recommendations. For the year 2000 screening, patients classified at moderate and high risk for PVD received special instructions and a card containing clearly printed information on the purpose of the Legs For Life screening, their level of risk for PVD, specific recommendations for follow-up, and phone numbers to call to help arrange for that follow-up. Two weeks after the screening, a second copy of this card was mailed to each moderate- and high-risk assessed patient. Four months later, each of these patients was contacted by telephone to determine if they had pursued additional care or testing. RESULTS: A total of 185 patients were screened, 42 (23%) of whom were determined to be at moderate or high risk for PVD. Four months after the screening, 39 (93%) of these patients were available for follow-up. Twenty (51%) patients had received no further medical advice or treatment. Nineteen (49%) patients had pursued further medical care which included physician consultation (n = 19; 100%), noninvasive Doppler evaluation (n = 10; 26%), diagnostic arteriography (n = 2; 5%), initiation of pharmacologic therapy for claudication (n = 1; 3%), percutaneous intervention (n = 1; 3%), or vascular surgery (n = 1; 3%). Seventeen of 39 patients (44%) reported that claudication-type leg pain was still a concern and/or lifestyle-limiting problem. CONCLUSION: Patients can be provided with problem-focused information and succinct physician recommendations at and soon after a screening for PVD, which can contribute to enhanced patient compliance. However, a host of personal, social, health, and physician-related issues still prevent a large percentage of patients from achieving relief of PVD-associated leg pain.
