Atherosclerosis III: Management01:26

Atherosclerosis III: Management

61
Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Peripheral Artery Disease III: Interprofessional Care

45
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...

Summary
This summary is machine-generated.

Decision aids (DAs) significantly reduced decisional conflict for patients with knee or hip osteoarthritis after their initial consultation. However, long-term effects remain uncertain due to significant patient follow-up loss.

Area of Science:

  • Orthopedics
  • Health Services Research
  • Patient Decision Making

Background:

  • Shared decision-making is increasingly important in healthcare.
  • Decision aids (DAs) support shared decision-making, particularly when treatment options have comparable outcomes.
  • Osteoarthritis (OA) of the knee or hip presents multiple treatment choices.

Purpose of the Study:

  • To evaluate the impact of decision aids (DAs) on reducing decisional conflict in patients with knee or hip osteoarthritis (OA).

Main Methods:

  • A multi-center, unblinded randomized controlled trial was conducted with 131 patients diagnosed with knee or hip OA.
  • Patients were randomized to receive standard care or standard care plus a DA.
  • Decisional conflict, satisfaction, and knowledge were assessed after the initial consultation, with follow-up at 26 weeks.

Main Results:

  • Patients receiving a DA reported significantly lower decisional conflict (mean DCS 25 vs. 39) immediately after the consultation.
  • The intervention group showed significantly higher satisfaction with information and the physician, and increased knowledge.
  • A substantial loss to follow-up (43%) limited the analysis of long-term outcomes at 26 weeks.

Conclusions:

  • Decision aids appear beneficial in reducing immediate decisional conflict for OA patients.
  • The long-term efficacy of decision aids in this patient group could not be confirmed due to follow-up attrition.
