Description

This measure is used to assess the percentage of ophthalmic anterior segment surgery patients diagnosed with toxic anterior segment syndrome (TASS) within 2 days of surgery.

Rationale

Toxic anterior segment syndrome (TASS), an acute, noninfectious inflammation of the anterior segment of the eye, is a complication of anterior segment eye surgery that typically develops within 24 hours after surgery. Various contaminants, including those from surgical equipment or supplies, have been implicated as causes of TASS. Although most cases of TASS can be treated, the inflammatory response associated with TASS can cause serious damage to intraocular tissues, resulting in vision loss. Prevention requires careful attention to solutions, medications, and ophthalmic devices and to cleaning and sterilization of surgical equipment because of the numerous potential etiologies. Despite a recent focus on prevention, cases of TASS continue to occur, sometimes in clusters. With millions of anterior segment surgeries being performed in the United States each year, measurement and public reporting have the potential to serve as an additional tool to drive further preventive efforts.

Clinical Practice Guidelines
The American Society of Cataract and Refractive Surgery Ad Hoc Task Force on Cleaning and Sterilization of Intraocular Instruments has published recommended practices for cleaning and sterilizing intraocular surgical instruments. The goal of these recommended practices is to prevent single-facility outbreaks of TASS related to contaminated or degraded instruments, and to facilitate the identification of causes of TASS and resolution of single-facility outbreaks of TASS when they occur.

All anterior segment surgery patients diagnosed with toxic anterior segment syndrome (TASS) within 2 days of surgery (see the related "Numerator Inclusions/Exclusions" field)

Type of Evidence Supporting the Criterion of Quality for the Measure

  • A clinical practice guideline or other peer-reviewed synthesis of the clinical research evidence
  • A formal consensus procedure, involving experts in relevant clinical, methodological, public health and organizational sciences

Extent of Measure Testing

The measures included in this implementation guide have been developed using a multi-step process. Each has been vetted with both an internal panel of technical experts and an external panel of individuals and/or organizations with relevant expertise. All of the measures have been pilot tested in ambulatory surgery centers (ASCs) and assessed for validity, feasibility and reliability.
