Quality assessment of cost and
economic studies
The papers were reviewed for quality of (i) the
source and methods of data collection and (ii)
prespecified criteria for reliable and comprehensive
economic evaluations. 50 Studies that were
not defined as full economic evaluations by the
author were not assessed on all categories of the
criteria. Papers were graded for six categories of
economic criteria, as follows.
• Study design:
(a) Good = meets criteria 1–7, 20 and 21
(b) Adequate = meets criteria 1, 3, 5, 6 and 20
(c) Inadequate = does not meet one or more of
criteria 1, 3, 5, 6 and 20.
• Effectiveness data:
(a) Good = meets criteria 8–11.
(b) Adequate = meets criteria 8 and 11.
(c) Inadequate = does not meet one or more of
criteria 8 and 11.
• Outcome data:
(a) Good = meets criteria 12–15.
(b) Adequate = meets criteria 12 and 14.
(c) Inadequate = does not meet one or more
of criteria 12 and 14.
• Cost data:
(a) Acceptable = meets criteria 16–19.
(b) Unacceptable = does not meet one or more
of criteria 16–19.
• Analysis:
(a) Good = meets criteria 22–35.
(b) Adequate = meets criteria 22, 23, 26, 27, 29,
30 and 31.
(c) Inadequate = does not meet one or more
of criteria 22, 23, 26, 27, 29, 30 and 31.
