A health technology assessment of Lovaas Autism Treatment : the role of evidence in legal, health policy and health care contexts Beard, Sandra Lynn
Abstract
In 1998 parents of autistic children launched a Charter of Rights and Freedoms challenge against the Province of BC for failing to fund Lovaas Autism Treatment (LAT) (Auton et al.). Although initially successful, in 2004 the Supreme Court of Canada overturned the lower courts' decisions and rejected the parents' claims for public funding. In addition to the Charter issue, these legal proceedings also highlighted the discourse over judicial policy making and the Courts' interpretation of medical evidence - specifically, the effectiveness of LAT. The use of medical evidence in law had been identified as an issue by both the American Institute of Medicine (IOM) and the Agency for Healthcare Research and Quality (AHRQ). This thesis was designed to expand on the lOM/AHRQ's previous work by investigating the conceptualizations and processes used by law, health policy and health care within the context of the Auton legal proceedings in order to gain an understanding of how each domain seeks, understands and applies evidence. This was accomplished in two parts. First, the legal dimension of a comprehensive health technology assessment (HTA) framework utilized a qualitative grounded theory methodology to examine participant interviews a n d legal documents. This analysis resulted in a conceptual framework of scientific evidence pathways that further defined, contextualized and dimensionalized the phenomena of seeking, understanding, and applying evidence within the three sectors. Grounded theory proved to be an effective approach for exploring the legal context and serves to broaden the scope of evidence HTA researchers can offer. Second, the effectiveness dimension of the HTA framework employed the methods of systematic review and critical appraisal to investigate the current state of knowledge on the effectiveness of LAT. This analysis concluded that there remains a paucity of rigorously designed studies due to ongoing methodological limitations. Overall, the strength of the body of evidence on LAT was poor and did little to advance its effectiveness claims. Together, these two analyses provided an update on the effectiveness of Lovaas Autism Treatment; insight into how the evidence of LAT was handled in the Auton case; and a depiction of how the sectors of law, health policy and health care conceptualize the evidentiary process in general.

Description |
In 1998 parents of autistic children launched a Charter of Rights and Freedoms challenge
against the Province of BC for failing to fund Lovaas Autism Treatment (LAT) (Auton et al.).
Although initially successful, in 2004 the Supreme Court of Canada overturned the lower courts'
decisions and rejected the parents' claims for public funding. In addition to the Charter issue,
these legal proceedings also highlighted the discourse over judicial policy making and the
Courts' interpretation of medical evidence - specifically, the effectiveness of LAT. The use of
medical evidence in law had been identified as an issue by both the American Institute of
Medicine (IOM) and the Agency for Healthcare Research and Quality (AHRQ). This thesis was
designed to expand on the lOM/AHRQ's previous work by investigating the conceptualizations
and processes used by law, health policy and health care within the context of the Auton legal
proceedings in order to gain an understanding of how each domain seeks, understands and
applies evidence. This was accomplished in two parts. First, the legal dimension of a
comprehensive health technology assessment (HTA) framework utilized a qualitative grounded
theory methodology to examine participant interviews a n d legal documents. This analysis
resulted in a conceptual framework of scientific evidence pathways that further defined,
contextualized and dimensionalized the phenomena of seeking, understanding, and applying
evidence within the three sectors. Grounded theory proved to be an effective approach for
exploring the legal context and serves to broaden the scope of evidence HTA researchers can
offer. Second, the effectiveness dimension of the HTA framework employed the methods of
systematic review and critical appraisal to investigate the current state of knowledge on the
effectiveness of LAT. This analysis concluded that there remains a paucity of rigorously designed
studies due to ongoing methodological limitations. Overall, the strength of the body of evidence
on LAT was poor and did little to advance its effectiveness claims. Together, these two analyses
provided an update on the effectiveness of Lovaas Autism Treatment; insight into how the
evidence of LAT was handled in the Auton case; and a depiction of how the sectors of law,
health policy and health care conceptualize the evidentiary process in general.
