This study provides robust evidence supporting the cost-effectiveness of smoking cessation programs for hospitalized patients .
In addition , the results indicated that the degree of cost-effectiveness of the inpatient smoking cessation program might not be related to either the components of the program or method ological variations in the cost-effectiveness analysis .
This systematic review examined the characteristics of published cost-effectiveness analyses of  inpatient smoking cessation programs  and assessed the method ological quality of the selected studies , to provide policymakers with economic evidence for this type of program .
Development and Validation of a Grading System for the Quality of Cost-Effectiveness Studies
Purpose .To provide a practical quantitative tool for appraising the quality of  cost-effectiveness ( CE ) studies . Methods .A committee comprised of health economists selected a set of criteria for the instrument from an item pool . Data collected with a conjoint analysis survey on 120 international health economists were used to estimate weights for each criterion with a r and om effects regression model . To vali date the grading system , a survey was sent to 60 individuals with health economics expertise . Participants first rated the quality  of three CE studies  on a visual analogue scale , and then evaluated each study using the  grading system . Spearman rho and Wilcoxon tests were used to detect convergent validity and analysis of covariance ( ANCOVA ) for discriminant validity . Agreement between the global rating by experts and the grading system was also examined . Results .Sixteen criteria were selected . Their coefficient estimates ranged from 1.2 to 8.9 , with a sum of 93.5 on a 100-point scale . The only insignificant criterion was “ use of subgroup analyses . ” Both convergent validity and discriminant validity of the grading system were shown by the results of the Spearman rho ( correlation coefficient = 0.78 , P < 0.0001 ) , Wilcoxon test ( P = 0.53 ) , and ANCOVA ( F3,146 = 5.97 , P = 0.001 ) . The grading system had good agreement with global rating by experts . Conclusions . The instrument appears to be simple , internally consistent , and valid for measuring the perceived quality of CE studies . Applicability for use in clinical and re source allocation decision-making deserves further study
