Implementation of Evidence-Based Practices within Treatment-As-Usual and Evidence-Based Practice Initiatives

Publicly funded initiatives are underway to improve implementation of evidence-based practices (EBP) in youth mental health services. However, we know little about the success of these initiatives or about EBP implementation independent of such initiatives. We examined EBP implementation in a treatment as usual (TAU) state and in six states with publicly funded EBP initiatives (EBPIs). In Study 1, we examined providers' use of practices derived from the evidence base (PDEB) and their predictors among 780 providers in a TAU state. In Study 2, we conducted a systematic review of implementation strategies, outcomes, and predictors of EBP use in six state funded EBPIs. Study 1 suggests TAU providers use PDEB alongside practices without consistent research support; provider racial/ethnic minority status, learning theory orientation, and manual use predict greater PDEB use. Study 2 indicates EBPIs employ multiple recommended implementation strategies with variable outcomes across studies and measurement approaches. Predictors of EBP use in EBPIs also varied, though training, setting, and youth age were consistent predictors across studies. While sample differences and inconsistent measurement across studies made direct comparisons somewhat tenuous, rates of PDEB use in the TAU sample appeared similar to those in publicly funded EBPIs. However, two states reported comparisons with TAU samples and found higher EBP implementation under EBPI. Different predictors impacted EBP use in TAU versus EBPIs. Our findings highlight the need for improved evaluation of EBPIs including clear reporting standards for outcomes and more consistent, standardized measurement of EBP use in order to better understand and improve EBPIs.

Effectiveness and cost-effectiveness of cognitive behavior therapy-enhanced compared with treatment-as-usual for anorexia nervosa in an inpatient and outpatient routine setting: a consecutive cohort study

BACKGROUND

For anorexia nervosa, firm evidence of the superiority of specialized psychological treatments is limited and economic evaluations of such treatments in real world settings are scarce. This consecutive cohort study examined differential (cost-)effectiveness for adult inpatients and outpatients with anorexia nervosa, after implementing cognitive behavioral therapy-enhanced (CBT-E) throughout a routine setting.

METHODS

Differences in remission, weight regain and direct eating disorder treatment costs were examined between one cohort (N = 75) receiving treatment-as-usual (TAU) between 2012-2014, and the other (N = 88) CBT-E between 2015-2017. The economic evaluation was performed from a health care perspective with a one-year time horizon, using EDE global score < 2.77, the absence of eating disorder behaviors combined with a BMI ≥ 18.5, as effect measure. Incremental cost-effectiveness ratios were calculated and cost-effectiveness planes and cost-effectiveness acceptability curves were displayed to assess the probability that CBT-E is cost effective compared to TAU.

RESULTS

Using direct eating disorder treatment costs in the cost-effectiveness analysis, the cost-effectiveness plane of the base case scenario for all patients indicated a 84% likelihood of CBT-E generating better health gain at additional costs. The median ICER is €51,081, indicating a probable preference for CBT-E (> 50% probability of cost-effectiveness) assuming a WTP of €51,081 or more for each additional remission, On remission, no difference was found with 9.3% remission during TAU and 14.6% during CBT-E (p = .304). Weight regain was higher during CBT-E (EMD = 1.33 kg/m², SE = .29, 95% CI [0.76-1.9], p < .001).

CONCLUSIONS

In this mixed inpatient and outpatient cohort study, findings indicate a probability of CBT-Ebeing more effective at higher costs. These findings may contribute to the knowledge of effectiveness and cost-effectiveness of specialized psychological treatments. In this study, the effectiveness and treatment costs of a specialized psychological treatment for adult clients with anorexia nervosa were compared with a regular, non-specialist treatment. One group of inpatients and outpatients did receive non-specialist treatment, the next group of inpatients and outpatients received CBT-E, a specialized treatment, later on. CBT-E is recommended for clients with bulimia and with binge eating disorder, for clients with anorexia nervosa it is less clear which specialized psychological treatment should be recommended. Results indicate that at end-of-treatment, CBT-E was not superior on remission. When looking at weight regain, CBT-E seemed superior than the treatment offered earlier. Economic evaluation suggests that CBT-E generates better health gain, but at additional costs. This study contributes to the knowledge on the effectiveness and treatment costs of psychological treatments, as they are offered in routine practice, to adults with anorexia nervosa.

Treatment-as-usual (TAU) is anything but usual: a meta-analysis of CBT versus TAU for anxiety and depression

OBJECTIVES

There were three aims of this study, the first was to examine the efficacy of CBT versus treatment-as-usual (TAU) in the treatment of anxiety and depressive disorders, the second was to examine how TAU is defined in TAU control groups for those disorders, and the third was to explore whether the type of TAU condition influences the estimate of effects of CBT.

METHOD

A systematic search of Cochrane Central Register of Controlled Trials, PsycINFO, and CINAHL was conducted.

RESULTS

48 studies of CBT for depressive or anxiety disorders (n=6926) that specified that their control group received TAU were identified. Most (n=45/48) provided an explanation of the TAU group however there was significant heterogeneity amongst TAU conditions. The meta-analysis showed medium effects favoring CBT over TAU for both anxiety (g=0.69, 95% CI 0.47-0.92, p<0.001, n=1318) and depression (g=0.70, 95% CI 0.49-0.90, p<0.001, n=5054), with differential effects observed across TAU conditions.

CONCLUSIONS

CBT is superior to TAU and the size of the effect of CBT compared to TAU depends on the nature of the TAU condition. The term TAU is used in different ways and should be more precisely described. The four key details to be reported can be thought of as "who, what, how many, and any additional treatments?"
