Venous leg ulceration has a high recurrence rate. Patients with healed or frequently recurring venous ulceration are required to perform self‐care behaviours to prevent recurrence or promote healing, but evidence suggests that many find these difficult to perform. Bandura's self‐efficacy theory is a widely used and robust behaviour change model and underpins many interventions designed to promote self‐care in a variety of chronic conditions. By identifying areas where patients may experience difficulty in performing self‐care, interventions can be developed to strengthen their self‐efficacy beliefs in performing these activities successfully. There are currently a variety of self‐efficacy scales available to measure self‐efficacy in a variety of conditions; but not a disease‐specific scale for use with venous ulcer patients. The aim of this study, therefore, was to develop and validate a disease‐specific, patient‐focused self‐efficacy scale for patients with healed venous leg ulceration. This scale will need further validation studies; however, it is ready for use in clinical practice and will enable practitioners to identify those patients who may need additional support in performing self‐care activities to prevent recurrence.  相似文献

Spinal cord injury (SCI) is associated with increased risk of pressure ulcers, but there are few published data about this in the United Kingdom (UK). This article represents a quantitative exploration of the occurrence of pressure ulcers in a UK spinal injuries unit (SIU). The technique used is a retrospective review of records: details of 144 completed first admissions for SCI between 1998 and 2000 were entered on to a database (SPSS) for analysis. Thirty-two per cent of patients already had pressure ulcers on admission to the SIU, while a total of 56% experienced an ulcer at some stage between injury and discharge from the SIU. Four pressure ulcer risk assessment scales were used (Waterlow, Braden, Norton and SCIPUS-A). These appeared to have moderate predictive power in this population. Pressure ulcers were found to be associated with increased length of hospital stay, density of lesion, surgical stabilization of neck injury before transfer to the SIU, tracheostomy on admission to the SIU and delayed transfer to the SIU after injury. Implications for practice are discussed.  相似文献

Aims and objectives. This review aims to explore the research available relating to three commonly used pain rating scales, the Visual Analogue Scale, the Verbal Rating Scale and the Numerical Rating Scale. The review provides information needed to understand the main properties of the scales. Background. Data generated from pain‐rating scales can be easily misunderstood. This review can help clinicians to understand the main features of these tools and thus use them effectively. Method. A MedLine review via PubMed was carried out with no restriction of age of papers retrieved. Papers were examined for methodological soundness before being included. The search terms initially included pain rating scales, pain measurement, Visual Analogue Scale, VAS, Verbal Rating Scale, VRS, Numerical/numeric Rating Scale, NRS. The reference lists of retrieved articles were used to generate more papers and search terms. Only English Language papers were examined. Conclusions. All three pain‐rating scales are valid, reliable and appropriate for use in clinical practice, although the Visual Analogue Scale has more practical difficulties than the Verbal Rating Scale or the Numerical Rating Scale. For general purposes the Numerical Rating Scale has good sensitivity and generates data that can be statistically analysed for audit purposes. Patients who seek a sensitive pain‐rating scale would probably choose this one. For simplicity patients prefer the Verbal Rating Scale, but it lacks sensitivity and the data it produces can be misunderstood. Relevance to clinical practice. In order to use pain‐rating scales well clinicians need to appreciate the potential for error within the tools, and the potential they have to provide the required information. Interpretation of the data from a pain‐rating scale is not as straightforward as it might first appear.  相似文献

Background

Genetic carrier screening is increasingly possible for many conditions, but it is important to ensure decisions are informed. The multidimensional measure of informed choice (MMIC) is a quantitative instrument developed to evaluate informed choice in prenatal screening for Down syndrome, measuring knowledge, attitudes and uptake. To apply the MMIC in other screening settings, the knowledge scale must be modified.

Objective

To develop and validate a modified MMIC knowledge scale for use with women undergoing carrier screening for fragile X syndrome (FXS).

Setting and participants

Responses to MMIC items were collected through questionnaires as part of a FXS carrier screening pilot study in a preconception setting in Melbourne, Australia.

Design

Ten knowledge scale items were developed using a modified Delphi technique. Cronbach''s alpha and factor analysis were used to validate the new FXS knowledge scale. We summarized the knowledge, attitudes and informed choice status based on the modified MMIC.

Results

Two hundred and eighty‐five women were recruited, 241 eligible questionnaires were complete for analysis. The FXS knowledge scale items measured one salient construct and were internally consistent (alpha = 0.70). 71% (172/241) of participants were classified as having good knowledge, 70% (169/241) had positive attitudes and 27% (65/241) made an informed choice to accept or decline screening.

Discussion and conclusions

We present the development of a knowledge scale as part of a MMIC to evaluate informed choice in population carrier screening for FXS. This can be used as a template by other researchers to develop knowledge scales for other conditions for use in the MMIC.  相似文献

The study is a validation study of two psychogeriatric depression rating scales, The Geriatric Depression Scale (GDS) and the Cornell Scale for Depression in Dementia (CSDD). The sensitivity and specificity, and the convergent and criterion validity of the two scales as well as the inter-rater reliability of the CSDD are reported. Two independent clinicians using the ICD-10 for depression and dementia, the Clinical Global Impression (CGI), the Hamilton Depression rating scale 17-items and the Mini-Mental-State Examination (MMSE), interviewed each patient or control subject. One hundred forty-five persons of 65 years or more of age were included, 73 were depressed only, 36 depressed and demented; 36 persons were control subjects, 11 of these were demented. The inter-rater reliabilities were high or very high equalling perfect correlation. There was very high convergent validity between the screening tools and the severity scales; the shorter versions of the GDS (15-, 10- or four-item version) had lower though still almost perfect correlations. The criterion validity in the total population showed the CSDD as the better scale with sensitivity and specificity of 93% and 97% with a cut-off value of ≥6. The GDS versions had sensitivities and specificities ranging from 82% to 90% and 75% to 94% respectively with cut-off values ≥9, 4, 3 and 1. The CSDD retained its validity and specificity as a screening tool for depression in a population of demented, while the GDS versions all diminished in validity. The GDS and the CSDD are both valid screening tools for depression in the elderly; however, the CSDD alone seems to be equally valid in populations of demented and non-demented.  相似文献
