Investigating barriers to implementation of the NICE Guidelines for Depression: a staff survey with Community Mental Health Teams

Clinical guidelines have been designed to lead to significant and consistent improvements in health care but are rarely fully implemented within healthcare services. The study involved a survey of staff at four Community Mental Health Teams, which aimed to assess their knowledge and use of both the psychological recommendations of the National Institute for Health and Clinical Excellence (NICE) guidelines for Depression and specifically of cognitive-behavioural therapy (CBT) based interventions. It also aimed to assess team members' clinical assessment skills and decision-making patterns when making recommendations about services for patients with depression. The results indicated that while over 90% of staff said they were using the NICE guidelines for Depression, less than 20% were very confident in using them. Most staff had knowledge about CBT and most (88%) would be very willing to refer to CBT but mentioned problems such as lack of resources and/or social problems affecting service delivery. Most staff were generally able to correctly identify the severity and type of depression. Despite this, some staff were making decisions that were not in accordance with the NICE recommendations. Reasons for these patterns are discussed.

Predictive value of early improvement in bipolar depression trials: a post-hoc pooled analysis of two 8-week aripiprazole studies

OBJECTIVE

To evaluate the value of early improvement to predict treatment outcome in patients with bipolar depression.

METHODS

Data were pooled from two aripiprazole, 8-week, randomized, double-blind, placebo-controlled trials in patients with bipolar depression without psychotic features to determine whether early improvement (≥20% reduction in Montgomery-Åsberg Depression Rating Scale (MADRS) Total score at Week 2 or 3) predicts later response (≥50% MADRS Total score reduction at Week 8) or remission (MADRS Total ≤10 at Week 8). Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated (LOCF). Univariate and multivariate logistic regression models were used to evaluate early improvement and baseline demographic/clinical characteristics as predictors of response/remission.

RESULTS

In total, 311 patients were randomized to placebo and 306 to aripiprazole. Predictive values of early improvement (≥20% MADRS Total score reduction) for remission with aripiprazole at Week 2/3, respectively, were: sensitivity 83%/94%; specificity 41%/33%; PPV 44%/45%; NPV 81%/91%. The corresponding values with placebo were as follows: sensitivity 70%/84%; specificity 60%/51%; PPV 50%/51%; NPV 77%/84%. Univariate linear regression showed that early improvement (≥15%, ≥20%, ≥25%, ≥30% at Week 3) was a significant potential predictor of remission.

CONCLUSION

Absence of early improvement after 3 weeks of treatment reliably predicted non-response/non-remission at study endpoint with high sensitivity and NPV. In patients with <20% improvement after 21 days of aripiprazole monotherapy, treatment should be modified, as continued use is unlikely to result in response/remission. Clinical decision-making to optimize treatment course in bipolar I depression may be appropriate after as little as 2 weeks and certainly within the first 3 weeks of treatment.

Entry site treatment to prevent late recurrent postoperative vitreous cavity haemorrhage after vitrectomy for proliferative diabetic retinopathy

AIMS

To assess the effectiveness of treatment to the inner sclerostomy sites at the time of vitrectomy for proliferative diabetic retinopathy (PDR) in reducing the incidence of late recurrent postoperative vitreous cavity haemorrhage (POVCH).

METHOD

Retrospective study of a consecutive series of 82 eyes undergoing vitrectomy for PDR by a single surgeon treated with either cryotherapy or argon laser directly to the inner sclerostomy site at the completion of surgery (treatment group). These were compared with a previous consecutive series of 82 eyes operated on by the same surgeon who did not have inner sclerostomy site treatment (control group). The occurrence of any POVCH was recorded within the first 6 months of surgery.

RESULTS

The composition of the two groups was similar in terms of age, indication for surgery and a variety of other preoperative factors. There were 64 patients in the control group and 65 in the treatment group. There was a significant reduction in the incidence of late recurrent POVCH in the treatment group. Late recurrent POVCH occurred in 12 (15%) eyes in the control group compared with five (6%) in the treatment group (p=0.03). The number of eyes requiring revision surgery within the first 6 months for late recurrent POVCH was four (5%) in the control group and two (2.5%) in the treatment group (p=0.31).

CONCLUSION

This study suggests that inner sclerostomy site treatment is effective in reducing the occurrence of recurrent late POVCH in patients undergoing vitrectomy for PDR. A randomised controlled study is needed to clarify this.

Rectal filling at planning does not predict stability of the prostate gland during a course of radical radiotherapy if patients with large rectal filling are re-imaged

AIMS

It has been suggested that large rectal filling is associated with an increased risk of prostate motion in radiotherapy. The aim of the present study was to determine if there is a correlation between rectal distension on planning computed tomography and the intrafraction and interfraction stability of the prostate gland during a course of radical radiotherapy for prostate cancer if a protocol was used to rescan patients with excessive rectal diameter during planning.

MATERIALS AND METHODS

The computed tomography planning scans of 89 patients with adenocarcinoma of the prostate treated with conformal radiotherapy were reviewed. All patients had three gold seed fiducial markers implanted into the prostate before planning computed tomography. About one in five patients had repeat computed tomography because their rectum was judged to be too large at the time of the first planning computed tomography. Rectal distension was assessed on planning computed tomography using outlines following European Organization for Research and Treatment of Cancer guidelines by measuring the rectal volume, the average cross-sectional area and the mean anterior-posterior diameter of the rectum. Daily kV images were obtained before and after treatment delivery to determine positional matching of the fiducial markers in the superior-inferior, anterior-posterior and right-left dimensions.

RESULTS

In total, 2860 pre- and post-treatment daily kV image pairs were obtained of 89 patients (average 32.1 image pairs per patient). The median rectal cross-sectional area was 7.3cm(2) (range 2.8-17.1), the median rectal volume was 54.8cm(3) (range 20.9-128.2), and the median anterior-posterior rectal diameter was 3.03cm (range 1.58-8.30). Unifactor linear regression models showed no statistically significant relationship between intra- and interfraction prostate stability and rectal volume on planning computed tomography.

CONCLUSIONS

No statistically significant relationship between rectal distension on planning computed tomography and the intra- and interfraction stability of the prostate gland was identified if patients with a large rectal volume were rescanned for planning.

A 16-week, Multicentre, Randomized, Open-label Study Assessing Effects of Aripiprazole Versus other Atypicals for Schizophrenia Patients with Metabolic Syndrome

Background:

Metabolic syndrome - a significant risk factor for cardiovascular morbidity and mortality - is twice as prevalent among psychiatric patients (21-63%) as general populations (20-24%). Although there is an inherent illness-associated metabolic risk, medications do contribute. Atypicals vary in metabolic risk from high (clozapine, olanzapine), moderate (risperidone, quetiapine) to low (aripiprazole, ziprasidone) (ADA, 2004). Few studies have comprehensively measured cardiovascular risk or directly compared antipsychotics. Limited controlled data show that antipsychotic-induced metabolic abnormalities may be reversible, rationalizing the switch to a lower-risk agent (DeNayer, 2004). Non-HDL-cholesterol encompasses all atherogenic cholesterols and provides a marker of CV risk: an increase of 29ng/dL in diabetics is associated with 50% increased risk (Jiang, 2004). Non-HDL-cholesterol is independently associated with increased risk of non-fatal myocardial infarction and angina.

Aim:

This study will provide cross-European data from 13 countries on MS rates in schizophrenia and will assess antipsychotic metabolic profiles and benefits of antipsychotic switching.

Methods:

In this ongoing, 16-week, open-label, European multicentre study, 258 schizophrenia patients treated for ≥3 months with olanzapine, risperidone or quetiapine and who have MS will be randomized to switch to aripiprazole (Week 1: 5mg/day; Week 2: 10mg/day; flexible 10-30mg/day after Week 2) or continue with previous antipsychotic. the primary objective is to demonstrate superiority of aripiprazole versus atypicals on mean percentage change of fasting non-HDL-cholesterol from baseline to Week 16.

Conclusion:

This study will provide the first direct and comprehensive comparison of metabolic risk with various atypicals in Europe and should impact the future management of schizophrenia.

Evaluation of Dyslipidaemia Risk among Patients Treated with Aripiprazole: Meta Analysis of Placebo- and Olanzapine-controlled Studies

Aims:

To evaluate dyslipidaemia risk among patients with schizophrenia treated with aripiprazole or olanzapine.

Methods:

Pooled analysis of the aripiprazole clinical database, including studies of ≥7 days with at least an oral aripiprazole monotherapy arm. Mean changes from baseline to endpoint and shifts from normal to abnormal lipid levels were calculated.

Results:

Seventeen placebo- and five olanzapine-controlled studies (3 weeks->3 years) of adult patients (≥18 years) were included. Mean changes (LOCF) in lipids were similar between aripiprazole and placebo for all lipid parameters; aripiprazole showed significant improvements versus olanzapine (p≤0.01). the incidence (OC) of switching to abnormal lipid levels from baseline normal was similar between placebo and aripiprazole, and significantly lower with aripiprazole than olanzapine for most measures.

Conclusion:

Despite limitations inherent to pooled analyses, these findings lend further support to the differential profile of atypicals, with aripiprazole showing effects on lipids comparable with placebo.
