Cost-effectiveness of focal psychodynamic therapy and enhanced cognitive-behavioural therapy in out-patients with anorexia nervosa

BACKGROUND

Anorexia nervosa (AN) is a serious illness leading to substantial morbidity and mortality. The treatment of AN very often is protracted; repeated hospitalizations and lost productivity generate substantial economic costs in the health care system. Therefore, this study aimed to determine the differential cost-effectiveness of out-patient focal psychodynamic psychotherapy (FPT), enhanced cognitive-behavioural therapy (CBT-E), and optimized treatment as usual (TAU-O) in the treatment of adult women with AN.

METHOD

The analysis was conducted alongside the randomized controlled Anorexia Nervosa Treatment of OutPatients (ANTOP) study. Cost-effectiveness was determined using direct costs per recovery at 22 months post-randomization (n = 156). Unadjusted incremental cost-effectiveness ratios (ICERs) were calculated. To derive cost-effectiveness acceptability curves (CEACs) adjusted net-benefit regressions were applied assuming different values for the maximum willingness to pay (WTP) per additional recovery. Cost-utility and assumptions underlying the base case were investigated in exploratory analyses.

RESULTS

Costs of in-patient treatment and the percentage of patients who required in-patient treatment were considerably lower in both intervention groups. The unadjusted ICERs indicated FPT and CBT-E to be dominant compared with TAU-O. Moreover, FPT was dominant compared with CBT-E. CEACs showed that the probability for cost-effectiveness of FTP compared with TAU-O and CBT-E was ⩾95% if the WTP per recovery was ⩾€9825 and ⩾€24 550, respectively. Comparing CBT-E with TAU-O, the probability of being cost-effective remained <90% for all WTPs. The exploratory analyses showed similar but less pronounced trends.

CONCLUSIONS

Depending on the WTP, FPT proved cost-effective in the treatment of adult AN.

How do patients with anorexia nervosa "process" psychotherapy between sessions? A comparison of cognitive-behavioral and psychodynamic interventions

OBJECTIVE

Patients' processing of psychotherapy between sessions ("inter-session process" (ISP)) has been repeatedly shown to be related to outcome. The aim of this study was to compare ISP characteristics of cognitive-behavioral vs. psychodynamic psychotherapy in the treatment of anorexia nervosa (AN) and their relation to outcome.

METHODS

Data of 106 patients participating in a randomized-controlled trial who received either 40 sessions of enhanced cognitive-behavioral therapy (CBT-E) or focal psychodynamic therapy (FPT) were analyzed. The ISP was measured with the Inter-session Experience Questionnaire (IEQ). Three outcome classes were distinguished: full recovery, partial recovery, and still fulfilling all AN criteria.

RESULTS

Patients receiving CBT-E reported more on "applying therapy" in the initial and the final treatment phase compared to FPT patients. In terms of process-outcome relations, higher levels of "recreating the therapeutic dialogue between sessions," "recreating the therapeutic dialogue with negative emotions" as well as "applying therapy with negative emotions" in the final phase of treatment predicted negative outcome in FPT, whereas overall higher levels of negative emotions predicted negative outcome in CBT-E.

CONCLUSIONS

In outpatient treatment in AN, the processing of therapy as measured by the IEQ showed surprisingly few differences between CBT-E and FPT. However, different ISP patterns were predictive of outcome, pointing to different mechanisms of change.

[Trauma and psychological distress in dermatological patients]

BACKGROUND

Although seldom diagnosed, post-traumatic stress disorder (PTSD) has a high prevalence in primary and tertiary care. In a consecutive cross-sectional study, the prevalence of traumatic experiences and the severity of post-traumatic symptoms as well as specific characteristics of traumatized patients in the context of the dermatological treatment were examined.

PATIENTS AND METHODS

Standardized questionnaires for assessing general psychopathology (Brief Symptom Inventory, BSI), coping with dermatological diseases (Adjustment to Chronic Skin Diseases Questionnaire, MHF) and diagnosis of trauma (Essen Trauma-Inventory, ETI) were used in 221 patients with different skin diseases.

RESULTS

In total, 85.1 % of the patients reported at least one potentially traumatic event in their lives, whereby psychometrically in 8.6 % of the cases the diagnostic criteria for a PTSD were met. Patients with suspected PTSD were more impacted by psychopathology, had more problems in coping with their skin diseases and attributed mental stress as having a greater influence on their skin disease than nontraumatized patients or traumatized patients without suspected PTSD. In addition, cumulative traumatization also leads to increased trauma symptomatology and greater difficulties in coping with skin diseases.

CONCLUSION

The results emphasize the impact of a comorbid PTSD on a patient's ability to cope with skin diseases and underline the need for the inclusion of the differential diagnosis PTSD in dermatological treatment settings.

Is there any association between disturbed gastrointestinal visceromotor and sensory function and impaired quality of life in functional dyspepsia?

BACKGROUND Functional dyspepsia (FD) is now categorized into the epigastric pain syndrome (EPS) and the postprandial distress syndrome (PDS). However, the role of disturbed gastric emptying and sensory function for the reduction of health-related quality of life (HRQOL) has not yet been studied in EPS and PDS. METHODS A total of 300 refractory FD patients and 450 healthy blood donors (BD) were studied. BD were stratified in subjects with (BD+) and without (BD-) concomitant FD symptoms. Gastric motor and sensory function, generic and disease-specific HRQOL [physical (PCS) and mental component summary (MCS)] and affective disorders were assessed. Twenty randomly selected BD-, 50 BD+ (36 PDS, 72%), and 110 FD (95 PDS, 86.4%) patients had additional function testing. KEY RESULTS Health-related quality of life was significantly reduced in FD patients (PCS = 40.7 +/- 8.8, MCS = 39.7 +/- 11.3, both P < 0.0001) compared to BD+ (PCS = 52.0 +/- 7.6, MCS = 49.0 +/- 9.4) and BD- (PCS = 56.0 +/- 4.3, MCS = 52.8 +/- 7.2). GET (t((1/2)), min) was significantly (both P < 0.0001) longer in FD patients (143.0 +/- 7.3) compared to BD+ (101.1 +/- 6.3) and BD- (73.8 +/- 7.6). FD patients scored significantly higher for 'pain' (P < 0.0001) and 'nausea' (P = 0.023), there was no difference for 'fullness' compared to BD. Impairment of GET was not associated with HRQOL. In FD patients, an augmented symptom response to the test meal (fullness, nausea) was associated with MCS, there was no difference between FD patients with EPS or PDS. CONCLUSIONS & INFERENCES In EPS and PDS, delayed gastric empting and altered sensory function are disease markers but not directly linked to the severity of HRQOL impairment or clinical presentation of FD.

Impairment of health-related quality of life in functional dyspepsia and chronic liver disease: the influence of depression and anxiety

BACKGROUND

Health-related quality of life (HRQOL) is a marker of disease severity. Data on the relative impairment of HRQOL in chronic liver disease (CLD) and functional gastrointestinal disorders are lacking and no studies have assessed the link between impairment of HRQOL and psychosocial factors yet.

AIM

To assess predictors for, and the impairment of, HRQOL in CLD and FD.

METHODS

In 181 functional dyspepsia (FD) patients, 204 CLD patients and 337 healthy blood donors, HRQOL was assessed with the Short Form-36 (mental and physical component), and anxiety and depression utilizing the Hospital Anxiety and Depression Scale.

RESULTS

Compared with HC, HRQOL is significantly lower in FD and CLD (P-value for all <0.001). The mental but not physical component of HRQOL was significantly more impaired in FD compared with CLD (P < 0.05). After adjusting for confounders, impairment of mental (P < 0.001) and physical (P = 0.005) component of HRQOL was associated with the severity of CLD and FD. In FD, the multivariate analysis revealed depression and severity of symptoms as the most important predictors of HRQOL (R2 = 21.9 and 7.1). In CLD, the mental component of HRQOL was associated with depression and anxiety (R(2) = 9.9 and 9.7).

CONCLUSIONS

In tertiary care, HRQOL is more severely impaired in FD compared with CLD. Co-morbid psychiatric conditions significantly contribute to the impairment of HRQOL.

Is there a benefit from intensified medical and psychological interventions in patients with functional dyspepsia not responding to conventional therapy?

AIM

In a prospective randomized, controlled trial, to compare the long-term outcome of intensive medical therapy (with or without cognitive-behavioural or muscle relaxation therapy) vs. standard medical therapy in patients with refractory functional dyspepsia (FD), referred to a tertiary referral medical center.

METHODS

A total of 100 consecutive FD patients were allocated to a standardized symptom-oriented 4 month therapy (SMT, n = 24), intensive medical therapy (IMT, medical therapy with testing-for and targeting-of abnormalities of motor-and-sensory function, n = 28) or IMT plus psychological interventions (either progressive-muscle relaxation (IMT-MR, n = 20) or cognitive-behavioural therapy (IMT-CBT, n = 28). The symptom intensity (SI) and health-related quality-of-life (HRQoL) after 12 months were prespecified primary outcome parameters.

RESULTS

After 12 months, significantly greater improvement of SI occurred in patients with IMT-all (with or without psychological interventions) compared with SMT (P < 0.025 vs. IMT-all). IMT, IMT-MR and IMT-CBT alone also resulted in significantly better improvement of the primary outcome parameters (P all < 0.025 vs. SMT). HRQoL significantly improved in all groups with intensive medical therapy but not standard medical therapy. Differences between intensive medical therapy-all and standard medical therapy were not significant. Concomitant anxiety and depression was improved significantly by IMT-CBT (vs. SMT) but not other treatments.

CONCLUSIONS

In FD patients with refractory symptoms, intensified medical management involving function testing and psychological intervention yields superior long-term-outcomes. Additional CBT may be effective for the control of concomitant anxiety and depression.
