Summary
Peripheral vascular procedures in the Veterans Health Administration (VHA) facilities, primarily for men, saw a slight decline from 1989-1998. VHA age-specific rates were higher for younger veterans compared to the general US population.
Area of Science:
- Vascular Surgery
- Health Services Research
- Epidemiology
Background:
- Peripheral vascular procedures are critical interventions for various vascular conditions.
- Understanding trends in these procedures within specific healthcare systems like the Veterans Health Administration (VHA) is essential for resource allocation and quality improvement.
Purpose of the Study:
- To analyze the trends in peripheral vascular procedures performed within Veterans Health Administration (VHA) facilities between 1989 and 1998.
- To compare age-specific rates of these procedures in the VHA population with the general US population.
Main Methods:
- Analysis of all VHA discharges with recorded peripheral vascular procedures from 1989-1998.
- Calculation of age-specific rates using the VHA user population.
- Evaluation of trends using frequency tables and Poisson regression.
Main Results:
- Over 55,000 peripheral vascular procedures were performed, almost exclusively in men.
- Key indications included peripheral vascular disease (53.7%), gangrene (19.3%), and surgical complications (13.3%).
- VHA age-specific rates were higher for ages 45-64, similar for 65-74, and lower for those 75+ compared to US rates. Rates declined slightly overall, with the largest decrease in men aged 45-65.
Conclusions:
- The VHA accounts for approximately 8% of all US peripheral vascular procedures in males.
- VHA age-specific rates exhibit differences from national rates, indicating a trend towards younger patients.
- A decrease in peripheral vascular procedure rates was observed across all age groups within the VHA from 1989 to 1998.

01:30Peripheral Artery Disease I: Introduction
Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:27Peripheral Artery Disease III: Interprofessional Care
Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

The nursing management of a patient with peripheral artery disease (PAD) begins with a thorough assessment of the patient’s health history and clinical manifestations.AssessmentHealth History: Evaluate the patient’s history of hypertension, hyperlipidemia, family history of cardiovascular issues, and lifestyle factors such as dietary patterns, smoking, and physical activity.Physical Examination:Assess the affected extremity for decreased or absent peripheral pulses, temperature changes,...

During the postoperative period, it is crucial to focus on maintaining circulation, identifying and managing potential complications, and planning for discharge.Nursing AssessmentVital signs monitoring: Regularly monitor vital signs, including blood pressure, heart rate, respiratory rate, and temperature, to detect early signs of complications such as bleeding and infection.Circulation assessment: Monitor pulses, perform Doppler assessments, and check capillary refill, color, temperature, and...
01:26Varicose Veins II: Diagnostic Studies and Interprofessional Care
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...
