A review of nursing skill-mix to optimise care in an acute trust

The main resource of the NHS is its workforce. However, achieving the correct mix of staff is crucial if it is to provide high-quality patient care in a cost-effective manner. When an acute trust was singled out in an independent analysis as having 'too rich' a skill-mix (compared with the rest of the strategic health authority), an internal review was undertaken to determine the ratio of qualified to unqualified nursing staff, and to compare these with acuity and dependency in each clinical area. The information was used to revise the nursing skill-mix within the trust.     

Are washable absorbents effective at containing urinary incontinence?

This article describes a pilot study to evaluate washable (or reusable) absorbent garments for adults with moderate to heavy urinary incontinence. The article will describe: The study process; How the individual products performed and how the washable and disposable products compared; How nurses can enable their patients to use washable products appropriately.     

The developmental, dimensional and diagnostic interview (3di): a novel computerized assessment for autism spectrum disorders

OBJECTIVE: Autism is a diagnostic spectrum of variable severity, with significant comorbidity. No existing standardized interview measures autistic features dimensionally. The authors aimed to develop a parental autism interview that could be administered to unselected clinical and general population samples that measures both symptom intensity and comorbidity across the full range of the autistic spectrum. METHOD: A computerized procedure was devised for administration by trained interviewers that generates symptom and diagnostic profiles for both autism and non-autistic conditions. Test-retest reliability and interrater reliability were assessed in unselected clinical (n = 50) and nonclinical (n = 30) populations. Concurrent validity (n = 120), discriminant validity (n = 120), and criterion validity (n = 29) were evaluated in autistic spectrum and non-autistic patients. RESULTS: Test-retest and interrater reliabilities were excellent (most intraclass correlation coefficients > 0.9). Concurrent validity (agreement with independent clinician formulation) was very good (mean kappa = 0.74). Criterion validity, a comparison with the Autism Diagnostic Interview, was excellent. Discrimination between autistic spectrum versus non-autistic subjects was almost perfect (sensitivity 1.0; specificity > 0.97). CONCLUSIONS: The Developmental, Dimensional and Diagnostic Interview (3di) provides an efficient and accurate means of assessing, in dimensional terms, the presence of autistic symptoms in both clinical and normal populations. It offers novel opportunities for those engaged in research and clinical practice.     

Tissue-specific response to interstitial angiotensin II in humans

Angiotensin II is synthesized locally in various tissues; however, the role of interstitial angiotensin II in the regulation of regional metabolism and tissue perfusion is not clear. We characterized the effect of interstially applied angiotensin II in skeletal muscle and subcutaneous adipose tissue of young, normal-weight, healthy subjects by using the microdialysis technique. Furthermore, we tested the hypothesis that the effect of interstitial angiotensin II is modulated by nitric oxide. Tissues were perfused with 0.01, 0.1, and 1 micro mol/L angiotensin II in the presence of the L- or D-isomer of N(G)-nitro-arginine-methyl ester (L- or D-NAME), the effective and noneffective isomer, respectively, for blocking nitric oxide synthase. Dialysate ethanol, glycerol, glucose, lactate, and pyruvate concentrations were measured to assess changes in blood flow (ethanol dilution technique), lipolysis, and glycolysis, respectively. Baseline blood flow and dialysate concentrations of the metabolites were similar with L- and D-NAME in both tissues. Blood flow and dialysate glucose and lactate did not change significantly in both tissues during perfusion with angiotensin II. Dialysate glycerol dose-dependently increased in adipose tissue (P<0.0438) but decreased in muscle (P<0.007). In muscle, dialysate pyruvate increased (P<0.0002), whereas lactate/pyruvate ratio decreased (P<0.001), both dose-dependently. All effects were similar with L- and D-NAME and could be reversed by nitroprusside. We conclude that in contrast to the profound hemodynamic effect of intravascular angiotensin II, interstitial angiotensin II has a minimal acute effect on blood flow in both tissues. However, interstitial angiotensin II modulates lipid and carbohydrate metabolism in a tissue specific fashion. Thus, the physiology of interstitial angiotensin II cannot be predicted from intravascular studies.     

Issues and concerns of couples presenting for preimplantation genetic diagnosis (PGD)

BACKGROUND: The use of preimplantation genetic diagnosis (PGD) to select genetically 'normal' human embryos and to transfer them to the uterus of a woman has generated considerable controversy. Debate has occurred over the implications of PGD, sex selection, safety of embryonic manipulation and eugenics. This study evaluates a range of social and moral concerns of couples towards PGD and assisted reproductive technologies (ART) prior to treatment to obtain unbiased authentic attitudes independent of the treatment cycle and the outcome. METHODS: A total of 121 subjects were administered a structured questionnaire after each couple's in vitro fertilization (IVF) or genetic counselling session. Group A consisted of 41 subjects presenting for PGD of single gene disorders (PGD-SG) and group B consisted of 48 subjects undertaking PGD for aneuploidy screening (PGD-AS). A control group consisted of 32 subjects that were about to commence their first IVF cycle. RESULTS AND DISCUSSION: All groups found PGD to be a highly acceptable treatment. They expressed little concern about its extension to testing non-disease states such as sex and they were strongly in favour of a shared decision-making model in which couples have considerable autonomy over decisions about the embryo(s) to transfer. Differences between the groups included issues surrounding the transfer of embryos, restrictions to PGD and the destruction of embryos.     

Overcoming the challenges of neuropathic pain

Neuropathic pain can originate from a variety of conditions. Early treatment is vital. Nurses have an important role in initiating treatment and providing ongoing pain management and support for patients.
