Predictors of disengagement from cognitive behavioural therapy for psychosis in a National Health Service setting: A retrospective evaluation.

OBJECTIVES: To evaluate whether demographic and clinical variables are related to disengagement rates in cognitive behavioural therapy (CBT) for psychosis in a clinical setting. METHODS: The medical records and symptom severity data (from Health of the Nation Outcome Scales) were analysed retrospectively for 103 referrals for CBT for psychosis in a National Health Service secondary care and Early Intervention in Psychosis team. RESULTS: Overall, 42.7% (n = 44) disengaged from CBT. There was no impact of gender or ethnicity, and no impact of clinical variables such as risk history and comorbid diagnosis. However, risk of disengagement was significantly higher for those who were younger, F = 6.89, partial η2  = .064, p = <.05; those with greater total HoNOS scores, F = 4.22, partial η2  = .04, p < .05; more severe symptoms on the HoNOS items of overactive, aggressive, disruptive, or agitated behaviour, χ2  = 6.13, p < .01; problem drinking or drug taking, χ2  = 7.65, p < .05; depressed mood, χ2  = 7.0, p < .01; and problems with occupation and activities: χ2  = 3.68, p < .05. There was a non-significant trend for shorter waiting times to be associated with greater levels of disengagement. CONCLUSIONS: These results indicate that it may not be psychosis per se that disrupts engagement in CBT, but linked behavioural and emotional factors. A more assertive approach to these factors - overactive, aggressive, disruptive, or agitated behaviour, problem drinking or drug taking, depressed mood, and problems with occupation and activities, particularly in younger people - may be valuable prior to or early on in therapy as a means of increasing engagement in CBT for psychosis. PRACTITIONER POINTS: Risk of disengagement from CBT for psychosis increases with overactive, aggressive, disruptive, or agitated behaviour (54.9% vs. 30.8%), problem drinking and drug taking (61.1% vs. 32.8%), depressed mood (56% vs. 30.2%), and problems with occupation and activities (53.3% vs. 34.5%), with a trend for younger age. An assertive and motivational approach to engagement and a focus on addressing low mood and problematic behaviours, prior to or early in therapy, may be warranted, particularly for younger people. This evaluation is limited by small sample size and being retrospective. These results speak to the question of whether psychosis itself renders people inappropriate for CBT for psychosis, or whether problems arise due to behavioural and emotional factors that might be addressed to increase access to CBT for psychosis.

A cross sectional survey examining the association between therapeutic relationships and service user satisfaction in forensic mental health settings.

BACKGROUND: This small-scale study examines an often neglected patient group (service users in forensic mental health settings). The research investigates their therapeutic relationship with staff and which therapeutic relationship factors are associated with their level of satisfaction with services. METHODS: A cross sectional survey was undertaken in two medium secure units in the UK with seventy seven participants completing self-report measures examining service user satisfaction with services and their therapeutic relationship with staff. Multiple regression analysis was used to identify the main predictor variables associated with satisfaction with the service provided. RESULTS: The respondents had a generally positive view of services and also of their therapeutic relationships with staff. However, the therapeutic relationship scores were lower than those recorded in community samples. One predictor variable was significantly associated with service user satisfaction; feeling respected and well regarded. CONCLUSIONS: The therapeutic relationship domain of being respected and well regarded by staff was identified as the most significant factor among the therapeutic relationship domains when examining the association with satisfaction with services. The important role mental health clinicians play in enabling service users to recognize they are being treated respectfully is noted as service users judge the degree of honesty, caring and interest that staff show in them. Staff also need to be available and accessible while having good listening and information giving skills. The importance of having both positive therapeutic relationships and service user satisfaction in forensic settings is also discussed.

Can 16-detector multislice CT exclude skeletal lesions during tumour staging? Implications for the cancer patient.

Current imaging guidelines recommend that many cancer patients undergo soft-tissue staging by computed tomography (CT) whilst the bones are imaged by skeletal scintigraphy (bone scan). New CT technology has now made it feasible, for the first time, to perform a detailed whole-body skeletal CT. This advancement could save patients from having to undergo duplicate investigations. Forty-three patients with known malignancy were investigated for bone metastasis using skeletal scintigraphy and 16-detector multislice CT. Both studies were performed within six weeks of each other. Whole-body images were taken 4 h after injection of 500 Mbq (99m)Tc-MDP using a gamma camera. CT was performed on a 16-detector multislice CT machine from the vertex to the knee. The examinations were reported independently and discordant results were compared at follow-up. Statistical equivalence between the two techniques was tested using the Newcombe-Wilson method within the pre-specified equivalence limits of +/-20%. Scintigraphy detected bone metastases in 14/43 and CT in 13/43 patients. There were seven discordances; four cases were positive on scintigraphy, but negative on CT; three cases were positive on CT and negative on scintigraphy. There was equivalence between scintigraphy and CT in detecting bone metastases within +/-19% equivalence limits. Patients who have undergone full whole-body staging on 16-detector CT may not need additional skeletal scintigraphy. This should shorten the cancer patient's diagnostic pathway.

16-MDCT in the detection of occult wrist fractures: a comparison with skeletal scintigraphy.

OBJECTIVE: Our objective was to assess the potential use of MDCT in the detection of occult scaphoid fractures. Fifty-one patients with suspected radiographically occult scaphoid fractures at 10-14 days after trauma were investigated prospectively with skeletal scintigraphy and CT on the same day. Planar images of the wrist were taken 3 hr after IV injection of 400 MBq of (99m)Tc-methylene diphosphonate using a single-head gamma camera. CT was performed on a 16-MDCT machine using 0.75-mm detectors and reconstruction in 0.5-mm slices. Multiplanar reformatted images were then viewed in interactive cine mode. The examinations were reported independently, and discordant results were compared at follow-up. CT was positive for wrist fracture in 14 (27.4%) of 51 patients and skeletal scintigraphy in 23 (45.1%) of 51 patients. Even after retrospective review, there were seven discrepant cases (13.7%), all of which were positive for wrist fracture on scintigraphy but negative on CT. Four of these seven patients with discordant findings underwent further radiography at 6 weeks, which did not show fracture. CONCLUSION: Although CT was preferred by most patients and was quicker, scintigraphy appears to detect bony abnormality more frequently. However, there appears to be an interesting group of patients (7/51) with normal initial radiography findings but positive scintigraphy findings who would normally be considered to have a fracture but for whom CT results were negative. In some of these patients, the results of follow-up radiography at 6 weeks were also negative, suggesting that this group of patients warrants further study.
