The Parkinson’s disease sleep scale: a new instrument for assessing sleep and nocturnal disability in Parkinson’s disease

Background: No formal instruments are available for quantifying sleep problems in Parkinson’s disease. Objective: To develop a new sleep scale to quantify the various aspects of nocturnal sleep problems in Parkinson’s disease, which may occur in up to 96% of affected individuals. Methods: Employing a multidisciplinary team approach, a visual analogue scale was devised addressing 15 commonly reported symptoms associated with sleep disturbance in Parkinson’s disease—the Parkinson’s disease sleep scale (PDSS). In all, 143 patients with Parkinson’s disease completed the PDSS, covering the entire spectrum of disease from newly diagnosed to advanced stage. As controls, 137 age healthy matched subjects also completed the scale. Test–retest reliability was assessed in a subgroup of subjects. The Epworth sleepiness scale was also satisfactorily completed by 103 of the patients with Parkinson’s disease. Results: PDSS scores in the Parkinson group were significantly different from the healthy controls. Patients with advanced Parkinson’s disease had impaired scores compared with early/moderate disease. Individual items of the scale showed good discriminatory power between Parkinson’s disease and healthy controls. Relevant items of the PDSS correlated with excessive daytime sleepiness. The scale showed robust test–retest reliability. Conclusions: This appears to be the first description of a simple bedside screening instrument for evaluation of sleep disturbances in Parkinson’s disease. A combination of subitems may help identify specific aspects of sleep disturbance, which in turn may help target treatment.

Diabetes Attitudes Wishes and Needs 2 (DAWN2): A multinational, multi-stakeholder study of psychosocial issues in diabetes and person-centred diabetes care

AIMS The Diabetes Attitudes Wishes and Needs 2 (DAWN2) study aims to provide a holistic assessment of diabetes care and management among people with diabetes (PWD), family members (FM), and healthcare professionals (HCPs) and explores potential drivers leading to active management. METHODS DAWN2 survey over 16,000 individuals (∼9000 PWD, ∼2000 FM of PWD, and ∼5000 HCPs) in 17 countries across 4 continents. Respondents complete a group-specific questionnaire; items are designed to allow cross-group comparisons on common topics. The questionnaires comprise elements from the original DAWN study (2001), as well as psychometrically validated instruments and novel questions developed for this study to assess self-management, attitudes/beliefs, disease impact/burden, psychosocial distress, health-related quality of life, healthcare provision/receipt, social support and priorities for improvement in the future. The questionnaires are completed predominantly online or by telephone interview, supplemented by face-to-face interviews in countries with low internet access. In each country, recruitment ensures representation of the diabetes population in terms of geographical distribution, age, gender, education and disease status. DISCUSSION DAWN2 aims to build on the original DAWN study to identify new avenues for improving diabetes care. This paper describes the study rationale, goals and methodology.

Health problems and health-related quality of life in people with multiple sclerosis

Objective: To explore the interrelationship between a number of common multiple sclerosis-related problems and health-related quality of life independent of the effect of physical disease impact. Design: A cross-sectional postal survey. Setting: The study was conducted in seven treatment centres within England. Subjects: Nine hundred and twenty-nine people with multiple sclerosis. Measures: The severity of the multiple sclerosis problems (fatigue, pain, urinary incontinence, bowel, depression, pressure ulcers, sexual and employment problems) was assessed using 5-point self-report ordinal scales. Disease impact was measured using the Multiple Sclerosis Impact Scale-29. Health-related quality of life was measured using the 36-Item Short Form Health Survey, version 2 (SF-36). The relationship between the problems, disease impact and health-related quality of life was determined using multivariate analysis of covariance. Results: Seventy four per cent of the sample experienced four or more of the selected problems. The extent and severity of problems increased with the level of disease impact (P B=0.001). Fatigue, pain, employment, depression and relationship problems were all found to have negative effect on the SF-36 scales independent to the effect of disease impact. SF-36 scores were most compromised in patients experiencing multiple problems. The data suggest an interdependent relationship between depression, fatigue and pain. Conclusion: The data suggest that many multiple sclerosis complications negatively affect health-related quality of life, independent of the effect of overall disease impact.

Informal carer activities, carer burden and health status in multiple sclerosis

Objective : To explore the contribution of carer characteristics, activities and disease impact to care burden and health in the multiple sclerosis caregiver population. Design : A prospective postal survey (24 months). Setting : The study was conducted in seven treatment centres within England. Subjects : Two hundred and fifty-seven caregivers of people with multiple sclerosis. Measures : Carer activity, the Caregivers Reaction Assessment Scale (CRA), the Short Form General Health Survey (SF-36), version 2, and care-related health problems. The carer data were linked to a comprehensive patient data set which permitted dyadic variables to be created measuring shared health. Results : Carers were engaged in a wide spectrum of physical care activities; lifting was the most frequent, 74% (n = 192). Patient disease impact scores were positively correlated (P < 0.01) with higher carer activity levels (r = 0.66). The carer activity level increased over time (P < 0.001 ) by around 5% with a mean increase of 0.22 (95% confidence interval (CI) 0.12—0.3) in the carer activity summary score (scale 0—4). Disease impact was negatively correlated (P < 0.01) with carer burden r = — 0.44 (CRA composite scale), physical health status r = —0.27 (SF-36 physical component score) and mental health status r = — 0.21 (SF-36 mental component score); and positively correlated with care-related health problems r = 0.44. Hierarchical regression models explaining 39% and 49% of the variance in care burden and health problem respectively showed that disease impact and dyadic health explained most of the variance, with carer activity contributing an additional 2% to 4% of the variance (P < 0.001). Conclusion : The analysis demonstrated that greater disease impact, lower dyadic health, high carer activity and greater carer burden are related to the level of carer-related health problems. The data suggested the need to develop interventions for assessing carers and reducing their activity levels and care burden (objective and subjective).

The nursing contribution to chronic disease management: A discussion paper

This paper explores the nature of the nursing contribution to chronic disease management (CDM) and identifies a number of key nursing activities within CDM both at the individual patient and care system levels. The activities were identified following a detailed review of the literature (160 reports and studies of nursing practice) relating to three tracer disorders: diabetes, chronic obstructive pulmonary disease and multiple sclerosis. The paper examines these activities collectively to generate models expressing some of the core functions of nursing within CDM. The paper illustrates some of the changing characteristics of nursing roles within CDM. More fundamentally, the paper questions the position of nursing in relation to the technologies that define CDM systems and proposes four levels of contribution: the nurse as technology; the nurse as technologist; the nurse as system engineer; and the nurse as architect. These different levels reflect distinctions in the nature of the nursing gaze and power relations within the health care workforce. The paper also highlights how nurses are failing to develop the evidence for their practice in CDM. The paper concludes that there is a need for some clear principles to guide clinical practice and encourage innovation in CDM. It is argued that the principles should not be rule-bound but define a distinctive nursing gaze that will position the nursing profession within the health care system and in relation to other professions. The gaze should incorporate the needs of the individual patient and the care system that they inhabit.

A systematic review of the effectiveness of negative pressure wound therapy in the management of diabetes foot ulcers

Foot ulcers are a common complication in patients with diabetes. Negative pressure wound therapy (NPWT) is a wound care therapy that is being increasingly used in the management of foot ulcers. This article presents a systematic review examining the effectiveness of this therapy. The review question is how effective is NPWT in achieving wound healing in diabetes foot ulcers? The primary outcome for this study was the number of patients achieving complete wound healing (secondary outcomes, other markers of wound healing, adverse events and patient satisfaction). A systematic literature review and tabulative synthesis of randomised controlled trials (RCTs). The review identified four RCTs of weak to moderate quality. Only one study examining NPWT in postamputation wound healing reported data on the primary outcome. These data show a 20% improvement in wound healing [odds ratios = 2·0%, confidence interval (CI) −1·0 to 4·0] and number needed to treat = 6 (CI 4–64). No serious treatment‐related complications were reported by any of the studies. One study suggested a reduction in the risk of secondary amputation (absolute risk reduction = 7·9%, CI 0·5–15·43). Studies also reported an increase in granulation and wound‐healing rates in patients treated with NPWT therapy. No data on patient satisfaction or experience were reported. While all the studies included in the review indicated that the NPWT therapy is more effective than conventional dressings, the quality of the studies were weak and the nature of the inquiries in terms of outcome and patient selection divergent. There is a strong need for larger trials to assess NPWT therapy in diabetes care with different groups of patients and in relation to different clinical objectives and parameters.

Clinical intervention research in nursing

As a healthcare profession nursing has a duty to develop practices that contribute to the health and well being of patients. The aim of this paper is to discuss current issues in clinical research within nursing. The paper defines clinical interventions research as a theoretically based, integrated and sequential approach to clinical knowledge generation. The paper provides specific criteria for defining a clinical intervention together with an overview of the stages involved in clinical research from problem identification to implementing knowledge in practice. The paper also explored the extent to which nursing research was focussed on clinical issues, through a snapshot review of all the original research papers in Europes three leading nursing research journals. In total of 517 different papers were included and classified in the review. Of these 88% (n=455) were classified as non-clinical intervention and 12% (n=62) as clinical intervention studies. The paper examined the intervention studies in detail examining: the underpinning theory; linkage to previous (pre-clinical) work; evidence of granularity; protocol clarity (generalisable and parsimonious); the phase of knowledge development; and evidence of safety (adverse event reporting). The paper discusses some of the shortcomings of interventions research in nursing and suggests a number of ideas to help address these problems, including: a consensus statement on interventions research in nursing; a register of nursing intervention studies; the need for nursing to develop clinical research areas in which to develop potential interventions (nursing laboratories); and a call for nursing researchers to publish more research in nursing specific journals.
