The management of trauma victims with head injury: a study by the national confidential enquiry into patient outcome and death

Introduction

In 2006 the National Confidential Enquiry into Patient Outcome and Death undertook a large prospective study of trauma care, which revealed several findings pertaining to the management of head injuries in a sample of 493 patients.

Methods

Case note data were collected for all trauma patients admitted to all hospitals accepting emergencies in England, Wales, Northern Ireland and the Channel Islands over a three-month period. Severely injured patients with an injury severity score (ISS) of ≥16 were included in the study. The case notes for these patients were peer reviewed by a multidisciplinary group of clinicians, who rated the overall level of care the patient received.

Results

Of the 795 patients who met the inclusion criteria for the study, 493 were admitted with a head injury. Room for improvement in the level of care was found in a substantial number of patients (265/493). Good practice was found to be highest in high volume centres. The overall head injury management was found to be satisfactory in 84% of cases (319/381).

Conclusions

This study has shown that care for trauma patients with head injury is frequently rated as less than good and suggests potential long-term remedies for the problem, including a reconfiguration of trauma services and better provision of neurocritical care facilities.     

Fertility of Spinal Cord Injured Males: Effect of Genitourinary Infection and Bladder Management on Results of Electroejaculation

ABSTRACT

Thirty-eight men undergoing electroejaculation (EEJ) procedures for anejaculatory infertility were examined for the presence or absence of infection in urine and semen. In 29 spinal cord injury patients, a high incidence of infected urine and infected semen (41% and 56%, respectively) was seen, in contrast to patients with normal bladder function (0% and 11 %).

Urinary infection was associated with slightly lower sperm quality and lower pregnancy rates (10% vs 30% in the presence of sterile urine). Semen infection had no effect on sperm counts or pregnancy rates. If intermittent self-catheterization (ISC) was used to empty the neurogenic bladder, slightly better sperm quality was seen, the total failure rate was less, and much better pregnancy rates (44%) resulted than for patients using an alternative bladder management (7%).

Antibiotics did not reduce the incidence of urine or semen infection, but did improve sperm counts slightly. Continuous prophylaxis was associated with bacterial resistance to many oral antibiotics and had no advantage over a short course of antibiotics prior to the procedure.

Despite the above associations, the sperm quality in our patient population was never normal compared with that of men who ejaculate normally. We conclude that the low sperm quality seen in electroejaculation specimens from spinal cord injured males is not due entirely to infection or to the type of bladder management. Short courses of antibiotics, instead of continuous antibiotic prophylaxis, may be beneficial. Intermittent catheterization is superior to other methods of neurogenic bladder management in maintaining the fertility of spinal cord injured men.     

The validity of patient- and clinician-rated measures of needs and the therapeutic relationship in psychosis: A pooled analysis

Measuring outcomes of treatments for psychosis such as needs and the quality of the therapeutic relationship is important in research and routine care. However, evidence on the validity of existing outcome measures is limited. We aimed to test the convergent, discriminant, and predictive validity of two widely used patient- and clinician-rated measures of needs and the therapeutic relationship. Multitrait-multimethod (MTMM) analysis was conducted on the Camberwell Assessment of Need Short Appraisal Schedule (CANSAS) and the Helping Alliance Scale (HAS), both the clinician (CANSAS-C, HAS-C) and patient (CANSAS-P, HAS-P) versions, in a pooled sample of 605 psychotic patients and their clinicians. CANSAS-C and CANSAS-P items loaded substantially into one common unmet needs factor. By comparison, substantial factor loadings were found for HAS-C and HAS-P items on two separate clinician- and patient-rated therapeutic relationship factors. Common unmet needs and clinician-rated therapeutic relationship factors significantly predicted reduced psychiatric in-patient days. Our findings support the convergent validity of the CANSAS, discriminant validity of the HAS, and predictive validity of CANSAS and HAS-C. The findings may inform the use of CANSAS and HAS as psychosis outcome measures in research and routine care.     

Divergent Patterns of Social Cognition Performance in Autism and 22q11.2 Deletion Syndrome (22q11DS)

Individuals with developmental disorders frequently report a range of social cognition deficits including difficulties identifying facial displays of emotion. This study examined the specificity of face emotion processing deficits in adolescents with either autism or 22q11DS compared to typically developing (TD) controls. Two tasks (face emotion recognition and weather scene recognition) were used to explore group differences in visual scanpath strategy and concurrent recognition accuracy. For faces, the autism and 22q11DS groups demonstrated lower emotion recognition accuracy and fewer fixations compared to the TD group. Individuals with autism demonstrated fewer fixations to some weather scene stimuli compared to 22q11DS and TD groups, yet achieved a level of recognition accuracy comparable to the TD group. These findings provide evidence for a divergent pattern of social cognition dysfunction in autism and 22q11DS.     

Using a hybrid model to investigate the comorbidity and symptom overlap between social phobia and the other anxiety disorders and unipolar mood disorders

New hybrid models of psychopathology have been proposed that combine the current categorical approach with symptom dimensions that are common across various disorders. The present study investigated the new hybrid model of social anxiety in a large sample of participants with anxiety disorders and unipolar mood disorders to improve understanding of the comorbidity and symptom overlap between social phobia (SOC) and the other anxiety disorders and unipolar mood disorders. Six hundred and eighty two participants from a specialized outpatient clinic for anxiety treatment completed a semi-structured diagnostic interview and the Multidimensional Assessment of Social Anxiety (MASA). A hybrid model symptom profile was identified for SOC and compared with each of the other principal diagnoses. Significant group differences were identified on each of the MASA scales. Differences also were identified when common sets of comorbidities were compared within participants diagnosed with SOC. The findings demonstrated the influence of both the principal diagnosis of SOC and other anxiety disorders and unipolar mood disorders as well as the influence of comorbid diagnoses with SOC on the six symptom dimensions. These findings highlight the need to shift to transdiagnostic assessment and treatment practices that go beyond the disorder-specific focus of the current categorical diagnostic systems.     

Are attitudes towards medication adherence associated with medication adherence behaviours among patients with psychosis? A systematic review and meta analysis

Background

Studies have shown patient attitudes to be an important predictor for health related behaviours including medication adherence. It is less clear whether patient attitudes are also associated with medication adherence among patients with psychoses.

Method

We conducted a systematic review and meta analysis of the data of studies that tested the association of attitude measures with medication adherence among patients with psychoses. 14 studies conducted between 1980 and 2010 were included.

Results

Results show a small to moderate mean weighted effect size (r ⁺ = 0.25 and 0.26 for Pearson and Spearman correlations, respectively).

Conclusions

Theory based interventions that target potentially modifiable attitude components are needed to assess the relationship between positive patient attitudes and adherence behaviours among patients with psychoses.
