Reliability and validity testing of the medicines related - consultation assessment tool for assessing pharmacists' consultations.

BACKGROUND: Demonstrating a person-centred approach in a consultation is a key component of delivering high-quality healthcare. To support development of such an approach requires training underpinned by valid assessment tools. Given the lack of a suitable pharmacy-specific tool, a new global consultation skills assessment tool: the medicines related-consultation assessment tool (MR-CAT) was designed and tested. AIM: This study aimed to test the validity and reliability of the MR-CAT using psychometric methods. METHOD: Psychometric testing involved analysis of participants' (n = 13) assessment of fifteen pre-recorded simulated consultations using the MR-CAT. Analysis included discriminant validity testing, intrarater and interrater reliability testing for each of the five sections of the MR-CAT and for the overall global assessment of the consultation. Analysis also included internal consistency testing for the whole tool. RESULTS: Internal consistency for the overall global assessment of the consultation was good (Cronbach's alpha = 0.97). The MR-CAT discriminated well for the overall global assessment of the consultation (p < 0.001). Moderate to high intrarater reliability was observed for the overall global assessment of the consultation and for all five sections of the MR-CAT (rho = 0.64-0.84) in the test-retest analysis. Moderate to good interrater reliability (Kendall's W = 0.68-0.90) was observed for the overall global assessment of the consultation and for all five sections of the MR-CAT. CONCLUSION: The MR-CAT is a valid and reliable tool for assessing person-centred pharmacist's consultations. Moreover, its unique design means that the MR-CAT can be used in both formative and summative assessment.

Educational supervision to support pharmacy professionals' learning and practice of advanced roles.

Pharmacy professionals are increasingly moving into advanced roles, including in primary care. In England, the publicly funded Pharmacy Integration Fund (PhIF) enabled employment and training of pharmacy professionals in new patient-facing roles, including general practice and care homes. In recognition of the need for support and supervision during work-based learning and building on established support structures in medicine and nursing, one of the providers of PhIF funded learning developed a supervision structure which mirrors arrangements for postgraduate medical specialty training. This paper describes what informed this supervision model, with a particular focus on educational supervision, its delivery, and the training which was developed to support supervisors. This supervision enabled pharmacy professionals moving into primary care to practise safely, manage workplace challenges, extend their roles and make progress with their education. This model illustrates the benefits of supervision in supporting post-registration learning to facilitate the development of advanced patient-facing clinical roles.

MRI features of bone marrow necrosis.

OBJECTIVE: The purpose of this study was to illustrate and review the MRI appearance of histologically proven cases of bone marrow necrosis (BMN) and to review the literature on this clinicopathologic entity with emphasis on its distinction from avascular necrosis (AVN) of bone. CONCLUSION: BMN is a rare clinicopathologic entity separate from AVN and has a distinctive MRI appearance. As MRI comes to play an increasingly important role in the evaluation of bone marrow disease, BMN is likely to be more frequently encountered. Awareness of BMN and its MRI appearance and appreciation of the frequent association between BMN and underlying malignancy may assist in the early diagnosis of BMN and initiate an intensive search for occult malignancy.

Immediate nephrectomy versus preoperative chemotherapy in the management of non-metastatic Wilms' tumour: results of a randomised trial (UKW3) by the UK Children's Cancer Study Group.

PURPOSE: To determine if patients receiving preoperative chemotherapy with vincristine and actinomycin D for non-metastatic Wilms' tumour have a more advantageous stage distribution and so need less treatment compared to patients who have immediate nephrectomy, without adversely affecting outcome. METHODS: Between 1991 and 2001, a total of 205 patients with newly diagnosed non-metastatic renal tumours, of which 186 had Wilms' histologies, were randomly assigned either to immediate surgery or to 6 weeks preoperative chemotherapy and then delayed surgery. Both groups of children received postoperative chemotherapy according to tumour stage and histology determined at the time of nephrectomy. RESULTS: There was a significant improvement in the stage distribution for patients with Wilms' histologies receiving delayed surgery compared to those having immediate nephrectomy (stage I: 65.2% versus 54.3%; stage II: 23.9% versus 14.9%; stage III: 9.8% versus 29.8%, chi2 test for trend=7.02, p=0.008). This improvement resulted in 20% fewer children receiving radiotherapy or doxorubicin yet event-free and overall survivals at 5 years of 79.6% and 89.0%, respectively, were similar in the two groups. CONCLUSION: Six weeks of preoperative chemotherapy with vincristine and actinomycin D results in a significant shift towards a more advantageous stage distribution and hence reduction in therapy, while maintaining excellent event free and overall survival in children with non-metastatic Wilms' tumour. Around 20% of survivors were therefore spared the late-effects of doxorubicin or radiotherapy. Our results suggest that all children with non-metastatic Wilms' tumour should receive chemotherapy prior to tumour resection.

Reassessing the role of the honeybee (Apis mellifera) Dufour's gland in egg marking.

Dufour's gland secretion may allow worker honeybees to discriminate between queen-laid and worker-laid eggs. To investigate this, we combined the chemical analysis of individually treated eggs with an egg removal bioassay. We partitioned queen Dufour's gland into hydrocarbon and ester fractions. The bioassay showed that worker-laid eggs treated with either whole gland extract, ester fraction or synthetic gland esters were removed more slowly than untreated worker-laid eggs. However, the effect only lasted up to 20 h. Worker-laid eggs treated with the hydrocarbon fraction were removed at the same rate as untreated eggs. The amount of ester which reduced the egg removal rate was far higher than that naturally found on queen-laid or worker-laid eggs, and at natural ester levels no effect was found. Our results indicate that esters or hydrocarbons probably do not function as the signal by which eggs can be discriminated.

Cytogenetic abnormalities and clinical outcome in Wilms tumor: a study by the U.K. cancer cytogenetics group and the U.K. Children's Cancer Study Group.

BACKGROUND: Tumor genetic features reported to correlate with adverse outcome in Wilms tumor include karyotype complexity, losses of material from the short arm of chromosome 1 and from the long arms of chromosomes 11, 16 and 22 and gain of material from the long arm of chromosome 1. This study sought to test these associations in a large series of tumors studied by cytogenetic analysis. Identification of markers associated with elevated risk of relapse and fatal outcome could allow more effective treatment stratification at presentation. PROCEDURE: Thirteen member laboratories of the U.K. Cancer Cytogenetics Group provided results from a 12-year period. Karyotype abnormalities were correlated with clinical data (age, tumor stage, and histology) and outcome data provided by the central register of the U.K. Children's Cancer Study Group. RESULTS: Of 127 abnormal karyotypes, 78 included a reputedly "poor prognosis" feature. Univariate survival analysis showed no significant adverse effect for karyotype complexity, 1p loss or 11q loss. The poor outcome of cases with 16q loss was of borderline significance, but this effect was restricted to those tumors with unbalanced translocation der(16)t(1q;16q). The association between relapse risk and gain of 1q material was not significant. Only monosomy 22 was a significant marker of poor outcome in univariate analysis (13 cases showing 50% relapse free survival at 5 years compared to 79% survival for the remaining 114 cases, P = 0.02). In multivariate analysis, significant independent predictors of poor outcome were 1q gain (Hazard Ratio 3.4), stage IV disease (HR 5.0), and monosomy 22 (HR 5.9). CONCLUSIONS: Loss of chromosome 22 identifies high risk Wilms tumors. The prognostic significance of 1q gain, 16q loss and unbalanced translocation der(16)t(1q;16q) is unresolved and warrants further investigation.
