Visual analog scales: do they have a role in the measurement of preferences for health states?

Visual analog scales (VASs) have long been used as a method of measuring preferences for health outcomes. They are easy and inexpensive to implement, can be administered quickly, and lend themselves to self-completion. Over time, however, disturbing questions have emerged concerning the validity of the VAS approach. This article reviews briefly the history, theory, practice, problems, and advantages of VASs; presents some suggestions to improve the validity of VASs; and recommends a limited but useful role for VASs in the process of measuring preferences for health states.

Venous disease treatment and compliance: the nursing role.

This article explores the numerous factors that influence compliance in the management of venous disease. The nurse's/health practitioner's role is highlighted as being pivotal in promoting compliance or non-compliance. The literature suggests there are many components that influence compliance, varying from impersonal relationships, treatment regimes and psychosocial influences. This implies that compliance is a shared responsibility between the healthcare practitioner/nurse and the patient. Holistic assessment incorporating negotiated care plans will provide the foundation of a partnership in care. Nurses have a responsibility to empower the patients with the necessary knowledge and skills to enable them to be an active participant in their own treatment/life regimes. Nurse education is key to effective, tolerable treatments that are acceptable to patients.
