The ethos brief index-validation of a brief questionnaire to evaluate wellness based on a holistic perspective in patients with restless legs syndrome. Sleep Breath 2024:10.1007/s11325-024-03058-5. [PMID: 38740633 DOI: 10.1007/s11325-024-03058-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Revised: 04/26/2024] [Accepted: 05/08/2024] [Indexed: 05/16/2024]
Abstract
PURPOSE The aim of this study was to validate the Ethos Brief Index (EBI) in patients with Restless Legs Syndrome (RLS). METHODS A cross-sectional design, including 788 subjects with RLS (65% women, 70.8 years, SD 11.3) from the Swedish RLS Association, was used. A postal survey was sent out to collect data regarding socio demographics, comorbidities, and RLS-related treatment data. Questionnaires included were EBI, the Restless Legs Syndrome-6 Scale (RLS-6), Restless Legs Syndrome-Quality of Life questionnaire (RLSQoL), the Insomnia Severity Index (ISI), and the Epworth Sleepiness Scale (ESS). The validity and reliability of the EBI were investigated using Rasch and confirmatory factor analysis (CFA) models. Measurement invariance, unidimensionality, and differential item functioning (DIF) across age and gender groups, as well as insomnia, daytime sleepiness, RLS-related QoL and RLS severity were assessed. RESULTS The results supported the unidimensionality of the EBI in the CFA (i.e., explaining 61.5% of the variance) and the Rasch model. The reliability of the EBI was confirmed using composite reliability and Cronbach's alpha. No DIF was identified for gender, age, insomnia, daytime sleepiness, RLS severity or RLS-related QoL. CONCLUSION The EBI showed good validity and reliability and operated equivalently for male and female patients with RLS. Accordingly, healthcare professionals can use the EBI as a psychometrically sound tool to explore and identify patient-centered problems related to the whole life situation.

The effect of psychosocial interventions for sexual health in patients with pelvic cancer: a systematic review and meta-analysis. Acta Oncol 2024; 63:230-239. [PMID: 38682457 DOI: 10.2340/1651-226x.2024.24204] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Accepted: 03/15/2024] [Indexed: 05/01/2024]
Abstract
AIM The aim of this systematic review and meta-analysis was to explore and evaluate the effect of psychosocial interventions in improving sexual health outcomes among post-treatment patients with pelvic cancer. METHODS Inclusion and exclusion criteria were pelvic cancer survivors; psychosocial interventions; studies with a control group and measures of sexual health. Five databases were searched for literature along with an inspection of the included studies' reference lists to extend the search. Risk of bias was assessed with the RoB2 tool. Standardised mean difference (SMD) with a random effects model was used to determine the effect size of psychosocial interventions for sexual health in patients with pelvic cancers. RESULTS Thirteen studies were included, with a total number of 1,541 participants. There was a large heterogeneity regarding the type of psychosocial intervention used with the source found in a leave one out analysis. Six studies showed statistically significant improvements in sexual health, while three showed positive but non-significant effects. The summary effect size estimate was small SMD = 0.24 (95% confidence interval [CI]: 0.05 to 0.42, p = 0.01). DISCUSSION There is limited research on psychosocial interventions for sexual health in pelvic cancer patients. There are also limitations in the different pelvic cancer diagnoses examined. Commonly, the included articles examined physical function rather than the whole sexual health spectrum. The small effect sizes may in part be due to evaluation of psychosocial interventions by measuring physical dysfunction. Future research should broaden sexual health assessment tools and expand investigations to more cancer types.

How patients with insomnia interpret and respond to the consensus sleep diary: a cognitive interview study. J Patient Rep Outcomes 2024; 8:19. [PMID: 38376583 PMCID: PMC10879077 DOI: 10.1186/s41687-024-00695-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Accepted: 02/01/2024] [Indexed: 02/21/2024] Open
Abstract
OBJECTIVE/BACKGROUND The Consensus Sleep Diary (CSD) is widely used to assess subjective sleep. Psychometric evaluations and focus-groups support its validity and clinical usefulness, but further research into its validity is needed. The aim of the study was to evaluate a Swedish translation of the CSD regarding test content and response processes in patients with insomnia. PATIENTS/METHODS In connection with translating the CSD into Swedish, we used cognitive interviewing to evaluate test content and the response process, that is, how people make decisions when responding to survey items. Cognitive interviews were conducted with 13 primary health care patients with insomnia disorder (mean age, 49 years; SD 15.5). Iterative, reparative analysis was used to investigate test content. Descriptive deductive analysis was used to investigate interview transcripts for the themes of the cognitive model: comprehension, retrieval, decision process, and judgement. Together, the themes explain the response process when responding to a patient-reported outcome measure. RESULTS The overall comprehension of the CSD could be affected by poor adherence to the instructions (comprehension). Patients had difficulty with recall if they did not complete the diary immediately in the morning and just before bedtime (retrieval). They could have problems deciding how to respond to certain items because they imbued sleep-related concepts with extra meaning (decision process), and had trouble finding response alternatives nuanced enough to describe their experience of sleep and tiredness (judgement). CONCLUSIONS This study contributes knowledge on how the instrument is perceived and used by care-seeking patients with insomnia. In this context, the CSD exhibits known flaws such as memory lapses if the diary is not filled in directly in the morning. To increase the accuracy of patients' responses, therapists should support patients in reading the instructions.

The meaning of continuity of care from the perspective of older people with complex care needs-A scoping review. Geriatr Nurs 2024; 55:354-361. [PMID: 38171186 DOI: 10.1016/j.gerinurse.2023.12.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 12/19/2023] [Accepted: 12/21/2023] [Indexed: 01/05/2024]
Abstract
People aged 65 years or older with complex care needs are at risk of fragmented care. This may jeopardise patient safety. Complex care needs are defined as care needs that require the performance of time-consuming processes such as reviewing medical history, providing counselling, and prescribing medications. A scoping review was conducted with the aim of mapping the literature regarding continuity of care from the perspective of older people with complex care needs. Search results from seven databases (PubMed, Cinahl, PsycInfo, ASSIA, Web of Science, Google Scholar, Scopus, DOAJ), grey literature (BASE), and a hand-search search of key journals were used. A deductive analysis based on aspects of continuity of care was performed. The search resulted in 5704 records. After a title and abstract screening, 93 records remained. In total, 18 articles met the inclusion criteria and were included in the scoping review. Older people´s sense of continuity of care increases when fewer healthcare workers are involved in their care but help from skilled professionals is more important than meeting the same person. It is vital for older people's feeling of continuity of care that discharge planning involves them, their families, and care providers in an organised way.

Validation of two brief instruments (the SURE and CollaboRATE) to measure shared decision-making in patients with restless legs syndrome. J Sleep Res 2023:e14071. [PMID: 37909257 DOI: 10.1111/jsr.14071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 09/20/2023] [Accepted: 10/02/2023] [Indexed: 11/02/2023]
Abstract
Restless legs syndrome (RLS) is a common neurological disorder characterised by an urge to move arms and legs, usually associated with discomfort, pain, motor restlessness, and sleep disturbance. An individually adapted treatment is needed but difficult to optimise, which makes shared decision-making (SDM) important. However, brief validated instruments on how patients with RLS perceive their involvement in treatment decisions are lacking. Therefore, the aim was to validate two instruments, SURE (Sure of myself, Understand information, Risk-benefit ratio, Encouragement, i.e., to assess decisional conflict) and CollaboRATE (brief patient survey focused on SDM, i.e., to assess SDM), in patients with RLS. A cross-sectional design, including 788 participants with RLS (65% females, mean [SD] age 70.8 [11.4] years) from a national patient organisation for RLS, was used. A postal survey was sent out to collect data regarding weight, height, comorbidities, demographics, and RLS-related treatment data. The following instruments were included: the SURE, CollaboRATE, Restless Legs Syndrome-6 Scale, and eHealth Literacy Scale. Confirmatory factor analysis and Rasch models were used to assess the validity and reliability of the SURE and CollaboRATE. Measurement invariance, unidimensionality, and differential item functioning (DIF) across age, gender, and medication groups were assessed. The SURE and CollaboRATE were both identified as unidimensional instruments with satisfactory internal consistency. No DIF across age and gender was identified, while significant DIF was observed for both the SURE and CollaboRATE regarding medication use categories. However, both the SURE and CollaboRATE are potential instruments to be used in research, but also as reflection tools by healthcare professionals, patients, and students to explore and assess SDM, and support its development in clinical care.

Sleep in cardiac arrest survivors. Nurs Crit Care 2023; 28:870-877. [PMID: 36168674 PMCID: PMC10947339 DOI: 10.1111/nicc.12843] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 08/16/2022] [Accepted: 09/14/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Insomnia, sleep apnoea and sleep loss are risk factors for the development of cardiovascular diseases. Most research on sleep disturbances includes patients with heart failure, while the role of sleep in sudden cardiac arrest survivors (SCA) has been only partially investigated and understood. Sleep-related breathing disorders and obstructive sleep apnoea increase illness and mortality in the aftermath of SCA. Also, post-traumatic stress is evident in SCA survivors, where sleep disruptions are some of the main symptoms of the condition. Consequently, it is important to identify sleep problems in SCA survivors at an early stage to avoid unnecessary suffering. AIM The aim of this study was to investigate registered nurses' perceptions of SCA survivors' sleep, both in hospital and after discharge. STUDY DESIGN This was an explorative interview study with a phenomenographic approach. Nineteen registered nurses (RNs) varying in age, sex and years in the profession participated. FINDINGS The nurses' perceptions of SCA survivors' sleep were categorized as: "The observer - noticing behaviours, emotions and habits of the patient that affect sleep", "The oblivious witness - attitudes that hinder the ability to recognise sleep behaviours", and "The practitioner - advising and medicating for sleep". The outcome space showed that the nurses detected both obvious and subtle signs relating to patients' sleep. However, attitudes hindering the recognition of sleep behaviours were independent of acting as an observer or practitioner. If nothing unforeseen was observed, or if the patient did not spontaneously raise the subject, sleep was considered less important than other health problems in SCA survivors. CONCLUSIONS Although the nurses knew that SCA survivors suffered from poor sleep, they failed to reflect on the consequences for the patient. Nurses' feelings of insufficient knowledge about sleep, as well as their omittance of sleep in the follow-up documentation could leave sleep issues unaddressed and cause unnecessary patient suffering. RELEVANCE TO CLINICAL PRACTICE Nurses need increased knowledge and training to enable them to detect subtle signs of sleep problems in SCA survivors.

Effects of Web-Based and Mobile Self-Care Support in Addition to Standard Care in Patients After Radical Prostatectomy: Randomized Controlled Trial. JMIR Cancer 2023; 9:e44320. [PMID: 37672332 PMCID: PMC10512115 DOI: 10.2196/44320] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 06/09/2023] [Accepted: 07/21/2023] [Indexed: 09/07/2023] Open
Abstract
BACKGROUND Prostate cancer is a common form of cancer that is often treated with radical prostatectomy, which can leave patients with urinary incontinence and sexual dysfunction. Self-care (pelvic floor muscle exercises and physical activity) is recommended to reduce the side effects. As more and more men are living in the aftermath of treatment, effective rehabilitation support is warranted. Digital self-care support has the potential to improve patient outcomes, but it has rarely been evaluated longitudinally in randomized controlled trials. Therefore, we developed and evaluated the effects of digital self-care support (electronic Patient Activation in Treatment at Home [ePATH]) on prostate-specific symptoms. OBJECTIVE This study aimed to investigate the effects of web-based and mobile self-care support on urinary continence, sexual function, and self-care, compared with standard care, at 1, 3, 6, and 12 months after radical prostatectomy. METHODS A multicenter randomized controlled trial with 2 study arms was conducted, with the longitudinal effects of additional digital self-care support (ePATH) compared with those of standard care alone. ePATH was designed based on the self-determination theory to strengthen patients' activation in self-care through nurse-assisted individualized modules. Men planned for radical prostatectomy at 3 county hospitals in southern Sweden were included offline and randomly assigned to the intervention or control group. The effects of ePATH were evaluated for 1 year after surgery using self-assessed questionnaires. Linear mixed models and ordinal regression analyses were performed. RESULTS This study included 170 men (85 in each group) from January 2018 to December 2019. The participants in the intervention and control groups did not differ in their demographic characteristics. In the intervention group, 64% (53/83) of the participants used ePATH, but the use declined over time. The linear mixed model showed no substantial differences between the groups in urinary continence (β=-5.60; P=.09; 95% CI -12.15 to -0.96) or sexual function (β=-.12; P=.97; 95% CI -7.05 to -6.81). Participants in the intervention and control groups did not differ in physical activity (odds ratio 1.16, 95% CI 0.71-1.89; P=.57) or pelvic floor muscle exercises (odds ratio 1.51, 95% CI 0.86-2.66; P=.15). CONCLUSIONS ePATH did not affect postoperative side effects or self-care but reflected how this support may work in typical clinical conditions. To complement standard rehabilitation, digital self-care support must be adapted to the context and individual preferences for use and effect.

Is insomnia associated with self-reported health and life satisfaction in cardiac arrest survivors? A cross-sectional survey. Resusc Plus 2023; 15:100455. [PMID: 37662641 PMCID: PMC10474489 DOI: 10.1016/j.resplu.2023.100455] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2023] [Revised: 07/19/2023] [Accepted: 08/05/2023] [Indexed: 09/05/2023] Open
Abstract
Background Insomnia symptoms seem to be common in cardiac arrest survivors but their associations with important outcomes such as self-reported health and life satisfaction have not previously been reported during the early post-event period. Therefore, the aim of the study was to investigate whether symptoms of insomnia are associated with self-reported health and life satisfaction in cardiac arrest survivors six months after the event. Methods This multicentre cross-sectional survey included cardiac arrest survivors ≥18 years. Participants were recruited six months after the event from five hospitals in southern Sweden, and completed a questionnaire including the Minimal Insomnia Symptom Scale, EQ-5D-5L, Health Index, Hospital Anxiety and Depression Scale, and Satisfaction With Life Scale. Data were analysed using the Mann-Whitney U test, linear regression, and ordinal logistic regression. The regression analyses were adjusted for demographic and medical factors. Results In total, 212 survivors, 76.4% males, with a mean age of 66.6 years (SD = 11.9) were included, and of those, 20% reported clinical insomnia. Insomnia was significantly associated with all aspects of self-reported health (p < 0.01) and life satisfaction (p < 0.001), except mobility (p = 0.093), self-care (p = 0.676), and usual activities (p = 0.073). Conclusion Insomnia plays a potentially important role for both health and life satisfaction in cardiac arrest survivors. Screening for sleep problems should be part of post cardiac arrest care and follow-up to identify those in need of further medical examination and treatment.

Patient safety and sense of security when telemonitoring chronic conditions at home: the views of patients and healthcare professionals - a qualitative study. BMC Health Serv Res 2023; 23:581. [PMID: 37340472 DOI: 10.1186/s12913-023-09428-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Accepted: 04/20/2023] [Indexed: 06/22/2023] Open
Abstract
BACKGROUND Chronic diseases are increasing worldwide, and the complexity of disease management is putting new demands on safe healthcare. Telemonitoring technology has the potential to improve self-care management with the support of healthcare professionals for people with chronic diseases living at home. Patient safety threats related to telemonitoring and how they may affect patients' and healthcare professionals' sense of security need attention. This study aimed to explore patients' and healthcare professionals' experiences of safety and sense of security when using telemonitoring of chronic conditions at home. METHODS Semi-structured interviews were conducted with twenty patients and nine healthcare professionals (nurses and physicians), recruited from four primary healthcare centers and one medical department in a region in southern Sweden using telemonitoring service for chronic conditions in home healthcare. RESULTS The main theme was that experiences of safety and a sense of security were intertwined and relied on patients´ and healthcare professionals´ mutual engagement in telemonitoring and managing symptoms together. Telemonitoring was perceived to increase symptom awareness and promote early detection of deterioration promoting patient safety. A sense of security emerged through having someone keeping track of symptoms and comprised aspects of availability, shared responsibility, technical confidence, and empowering patients in self-management. The meeting with technology changed healthcare professionals' work processes, and patients' daily routines, creating patient safety risks if combined with low health- and digital literacy and a naïve reliance on technology. Empowering patients' self-management ability and improving shared understanding of the patient's health status and symptom management were prerequisites for safe care and the patient´s sense of security. CONCLUSIONS Telemonitoring chronic conditions in the homecare context can promote a sense of security when care is co-created in a mutual understanding and responsibility. Attentiveness to the patient's health literacy, symptom management, and health-related safety behavior when using eHealth technology may enlighten and mitigate latent patient safety risks. A systems approach indicates that patient safety risks related to telemonitoring are not only associated with the patient's and healthcare professionals functioning and behavior or the human-technology interaction. Mitigating patient safety risks are likely also dependent on the complex management of home health and social care service.

Abstract
OBJECTIVE To explore communication about medication management during annual consultations in primary care. DESIGN passive participant observations of primary care consultations. SETTING Two primary care centres in southern Sweden. PARTICIPANTS Consultations between 18 patients (over the age of 60 years) with chronic diseases and 10 general practitioners (GPs) were observed, audio-recorded, transcribed and analysed using content analysis. RESULTS Four categories emerged: communication barriers, striving for a shared understanding of medication management, evaluation of the current medication treatment and the plan ahead and behavioural changes in relation to medication management. Misunderstandings in communication, failure to report changes in the medication treatment and use of generic substitutes complicated mutual understanding and agreement on continued treatment. The need for behavioural changes to reduce the need for medication treatment was recognised but should be explored further. CONCLUSION Several pitfalls, including miscommunication and inaccurate medication lists, for safe medication management were identified. The purpose of annual consultations should be clarified, individual treatment plans could be used more actively during primary care consultations and efforts are needed to improve verbal communication and information continuity.

Following a standardised pathway: Healthcare professionals' perspectives on person-centred care within ERAS for patients with colorectal cancer. J Clin Nurs 2022. [PMID: 36262024 DOI: 10.1111/jocn.16562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 09/28/2022] [Accepted: 10/04/2022] [Indexed: 11/29/2022]
Abstract
AIMS AND OBJECTIVES To describe healthcare professionals' perceptions of person-centred care for patients with colorectal cancer, within the standardised care concept of Enhanced Recovery After Surgery. BACKGROUND International guidelines for colorectal surgery describe standardised perioperative care. Combining standardised care with person-centred care could be accomplished using the person-centred nursing framework for establishing and maintaining relationships with patients. Despite strong evidence for the standardised care concepts' medical benefits, studies concerning the practice of person-centred care from a nursing point of view are sparse. DESIGN A qualitative descriptive design was used. METHODS Four focus groups interviews were performed including 22 healthcare professionals with 1-29 years' experience of caring for patients with colorectal cancer. Data were analysed using qualitative conventional content analysis. The COREQ checklist for reporting qualitative research was used. RESULTS Three themes emerged in the analysis; Framework in the healthcare system, Facing differences in participation and Interacting with the person beyond the illness. Conditions for person-centred care were related to the interactions between patients and healthcare professionals, the structure of care were also considered relevant. CONCLUSION There is a discrepancy between what is considered important to do and what is done in clinical practice to create conditions for patient participation. Interacting with patients and creating an interprofessional environment are important conditions, the structure of care is also a fundamental key to promoting person-centred care. There is a need for further improvement in care of patients with colorectal cancer to achieve person-centredness within standardised care. RELEVANCE TO CLINICAL PRACTICE The findings provide valuable insights into what healthcare professionals consider to be important for achieving person-centred care. This knowledge can be useful in clinical practice and education programs. PATIENT OR PUBLIC CONTRIBUTION At the outset of the study, three patients were interviewed aimed at improving the conditions for the healthcare professionals' focus groups.

Predictors of problems reported on the EQ-5D-3L dimensions among people with impaired vision in northern Portugal. Health Qual Life Outcomes 2022; 20:132.

Abstract
BACKGROUND The EQ-5D index often fails to detect the effect of ophthalmic diseases and sight loss. Investigating predictors of individual EQ-5D health dimensions might reveal the underlying reasons. The aim of this study was to investigate predictors of health dimension ratings obtained with the EQ-5D-3L from participants with impaired vision representing a spectrum of eye diseases. METHODS Observational cross-sectional study with participants recruited at four public hospitals in Portugal. Outpatients with visual acuity of 0.30 logMAR(6/12) or worse in the better-seeing eye were invited to participate. Participants completed two instruments: the EQ-5D-3L (measures participants' perceived health-related quality-of-life) and the Massof Activity Inventory (measures visual ability-ability to perform vision-related activities). This study used logistic regression models to identify factors associated with responses to the EQ-5D-3L. RESULTS The study included 492 participants, mean age 63.4 years (range = 18-93), 50% females. The most common diagnosis was diabetic retinopathy (37%). The mean visual acuity in the better seeing eye was 0.65 logMAR (SD = 0.48) and the mean visual ability was 0.62 logits (SD = 2.04), the correlation between the two was r = - 0.511 (p < 0.001). Mobility and self-care were the health dimensions with the fewest problems (1% reported extreme problems), anxiety and depression the dimension with the most problems (24% reported extreme problems). ROC curve analysis showed that the EQ-5D index was a poor predictor of cases of vision impairment whilst visual ability given was a good predictor of cases of vision impairment. Visual ability was an independent predictor of the response for all dimensions, higher ability was always associated with a reduced odds of reporting problems. The odds of reporting problems were increased for females in 3 out of 5 dimensions. Comorbidities, visual acuity and age-category were predictors of the odds of reporting problems for one dimension each. CONCLUSIONS The odds of reporting problems for the five health dimensions of the EQ-5D-3L were strongly influenced by the ability to perform vision-related activities (visual ability). The EQ-5D index showed poor performance at detecting vision impairment. These findings are informative and relevant for the clinic and for research evaluating the impact of eye diseases and disease treatments in ophthalmology.

Health care professionals' experiences of how an eHealth application can function as a value-creating resource - a qualitative interview study. BMC Health Serv Res 2021; 21:1203. [PMID: 34740340 PMCID: PMC8570238 DOI: 10.1186/s12913-021-07232-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Accepted: 10/28/2021] [Indexed: 11/11/2022] Open
Abstract
Background The number of patients with one or more chronic conditions is increasing globally. One strategy to achieve more sustainable care for these patients is by implementing use of home-based eHealth applications. Such services support patients to take on a more active role as value-creating co-producers of their own care, in collaboration with health care professionals. Health care professionals have a key role in the value creation process, but little is known about value formation within eHealth interactions, especially from their perspective. Therefore, this study aimed to provide a deeper understanding of how an eHealth application can function as a value-creating resource from the perspective of health care professionals. Methods Semi-structured interviews were conducted with thirteen health care professionals (nurses, physicians and first-line managers). Qualitative content analysis was used to analyze the interviews. Results The findings indicate that value formation processes are strongly influenced by the organizational preconditions and by the usability and functionality of technology. The experiences of the health care professionals indicated that value was conceptualized in dimensions of meaningfulness, building of relationships, building safety and feelings of trust. Although these dimensions were mainly expressed in a positive way, such as perceived improvement of medical care, accessibility and continuity, they also had a negative side that caused value destruction. This was primarily due to patient difficulties in using the application or making measurements. Subsequent efforts at value recovery resulted in value creation, but were often time-consuming for the professionals. Conclusions This study contributes by extending conceptualizations of value to the role of health care professionals and by highlighting technology as sometimes facilitating and sometimes hampering value formation processes. The findings indicate that the eHealth application was a value-creating resource, facilitating proactive communication and supporting patients’ engagement and control over their self-care. However, for the application to become a more valuable resource in practice and counteract inequity in care, it needs to be further developed to be adapted to the needs and preconditions of patients.

Abstract
Background: Mobility and balance is essential for older adults' well-being and independence and the ability to maintain physically active. Early identification of functional impairment may enable early risk-of-fall assessments and preventive measures. There is a need to find new solutions to assess functional ability in easy, efficient, and accurate ways, which can be clinically used frequently and repetitively. Therefore, we need to understand how functional tests and expert assessments (EAs) correlate with new techniques.Objective: To explore whether the skeleton avatar technique (SAT) can predict the results of functional tests (FTs) of mobility and balance: Timed Up and Go (TUG), the 30-s chair stand test (30sCST), the 4-stage balance test (4SBT), and EA scoring of movement quality.Methods: Fifty-four older adults (+65 years) were recruited through pensioners' associations. The test procedure contained three standardized FTs: TUG, 30sCST, and 4SBT. The test performances were recorded using a three-dimensional SAT camera. EA scoring was performed based on the video recordings of the 30sCST. Functional ability scores were aggregated from balance and mobility scores. Probability theory-based statistical analyses were used on the data to aggregate sets of individual variables into scores, with correlation analysis used to assess the dependency between variables and between scores. Machine learning techniques were used to assess the appropriateness of easily observable variables/scores as predictors of the other variables included.Results: The results indicate that SAT data of the fourth 4SBT stage could be used to predict the aggregated results of all stages of 4SBT (with 7.82% mean absolute error), the results of the 30sCST (11.0%), the TUG test (8.03%), and the EA of the sit-to-stand movement (8.79%). There is a moderate (significant) correlation between the 30sCST and the 4SBT (0.31, p = 0.03), but not between the EA and the 30sCST.Conclusion: SAT can predict the results of the 4SBT, the 30sCST (moderate accuracy), and the TUG test and might add important qualitative information to the assessment of movement performance in active older adults. SAT might in the future provide the means for a simple, easy, and accessible assessment of functional ability among older adults.

Abstract
OBJECTIVE To evaluate patients' experiences of using a web-based application, especially its usability as support for self-care activities after prostate cancer surgery. DESIGN A deductive content analysis was used, stemming from the Fit between Individuals, Task and Technology (FITT) framework. SETTING One surgical department in south of Sweden between October 2015 and April 2016 and between September 2017 and July 2018. PARTICIPANTS Fifteen men who had undergone radical prostatectomy for prostate cancer. RESULTS By organising data in accordance with the FITT model, three main categories with ten subcategories were identified. Patients gave feedback on functions that suited them and their needs, as well as potential adjustments and improvements. Patients experienced that ePATH gave them easy access to reliable information regarding their rehabilitation. Directed information about ePATH at enrolment was seen as important. ePATH was perceived to have a logical structure that was easy to follow. However, when the structure was unclear, patients became less motivated to use a function. CONCLUSIONS Patients experienced ePATH as satisfactorily user-friendly and useful as a complementary self-management support after prostate cancer surgery, especially when the information and tasks were tailored to their preferences and the system design features supported individual autonomy.

Validation of the patient activation measure in patients at discharge from hospitals and at distance from hospital care in Sweden. BMC Public Health 2019; 19:1701. [PMID: 31856796 PMCID: PMC6921492 DOI: 10.1186/s12889-019-8025-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2019] [Accepted: 11/29/2019] [Indexed: 12/11/2022] Open
Abstract
Background The Patient Activation Measure (PAM) is a recognized measure of how active patients are in their care, and has been translated into several languages and cultural contexts. Patient activity, self-care, and health literacy have become increasingly important aspects of health care, and thus reliable measures of these are needed. However, a Swedish translation of PAM is currently lacking. The aim of the study was to translate and assess the validity and reliability of the Swedish PAM-13. Methods A self-report questionnaire was handed out to 521 patients at ten medical, geriatric, and surgical wards, and one Virtual Health Room. The Rasch model was employed, using the partial credit model, to assess the functioning of the PAM scale, item fit, targeting, unidimensionality, local independence, differential item functioning (DIF), and person-separation index. Evidence of substantive, content, structural, and external validity was examined. Results Of the 521 patients who were consecutively handed a questionnaire, 248 consented to participate, yielding a response rate of 47.6%. The average measure for each category advanced monotonically. The difficulty of the PAM items ranged from − 1.55 to 1.26. The infit and outfit values for the individual items were acceptable. Items 1, 2, and 4 showed disordered thresholds. The mean person location was 1.48 (SD = 1.66). The person-item map revealed that there were no item representations at the top of the scale. The evidence for unidimensionality was ambiguous and response dependency was seen in some items. DIF was found for age. The person separation index was 0.85. Conclusion The Swedish PAM-13 was reliable, but was not conclusively found to represent one underlying construct. It seems that the Swedish PAM-13 lacks strong evidence for substantive, content, and structural validity. Although valid and reliable measures of ability for activation in self-care among patients are highly warranted, we recommend further development of PAM-13 before application in everyday clinical care.

Adherence to oxygen saturation targets increased in preterm infants when a higher target range and tighter alarm limits were introduced. Acta Paediatr 2019; 108:1584-1589. [PMID: 30951230 DOI: 10.1111/apa.14808] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2018] [Revised: 03/04/2019] [Accepted: 04/01/2019] [Indexed: 01/22/2023]
Abstract
AIM European consensus guidelines published in May 2013 recommended a target peripheral capillary oxygen saturation (SpO2 ) range of 90-95% for preterm infants. These were incorporated into guidelines at the Karolinska University Hospital, Sweden, in November 2013. This study compared clinical practice before and after those local guidelines. METHODS We included infants who were born between 23 + 0 and 30 + 6 weeks from January 1, 2013 to December, 31 2015 and received intensive care in two Karolinska units. The lower saturation target of 88-92% and alarm limits of 85-95% used before November 2013 were compared to the new higher saturation target of 90-95% and alarm limits of 89-96%. RESULTS Data from 399 infants were analysed. The mean SpO2 was 92.4% with the higher target (n = 301) and 91.1% with the lower target (n = 98). Using the higher instead of lower target meant that the SpO2 was within the prescribed target range more frequently (51% versus 30%) and the proportion of time with SpO2 >95% was increased by 9% (95% confidence interval 7-11%, p < 0.001). CONCLUSION The higher saturation target and tighter alarm limits led to higher mean oxygen saturation, increased adherence to the target and increased time with hyperoxaemia.

Abstract
Background Prostate cancer has increased in incidence worldwide and is the leading cause of cancer death in 24 countries. The most common treatment is radical prostatectomy. However, surgery is associated with postoperative complications such as urinary incontinence and sexual dysfunction, causing decreased quality of life. If survivors are encouraged to be more active in self-care management, the symptom burden may decrease and quality of life may improve. An electronic health (eHealth) intervention based on motivational behavioral theory has been developed for this purpose. Objective This study aimed to compare the effectiveness of standard care in combination with a tailored eHealth and mobile health self-management support system, electronic Patient Activation in Treatment at Home (ePATH), with standard care of adverse effects of prostate cancer treatment (urinary incontinence and sexual functioning) in men undergoing radical prostatectomy. The secondary aim was to test the effect on patient activation, motivation, overall well-being, and health literacy over time in and between groups. Methods A pragmatic multicenter, block-randomized controlled trial with 2 study arms, standard care (control) and eHealth-assisted standard care (intervention), for patients undergoing radical prostatectomy. For 80% power, a sample of 242 men will need to be recruited. Results Recruitment started in January 2018 and is expected to be completed by August 2019. Data collection will be completed in August 2020. The first cross-sectional results from this trial are anticipated to be published in January 2020. Conclusions With the increasing number of prostate cancer survivors, attention should be paid to rehabilitation, psychosocial care, and support for endurance of self-care to reduce suffering from adverse treatment effects, poor quality of life, and depression because of postoperative complications. This project may increase knowledge of how patients can be supported to feel involved in their care and returning to as normal a life as possible. The anticipated effects of ePATH could improve health outcomes for individuals and facilitate follow-up for health care professionals.

Abstract
OBJECTIVES This study aimed at investigating the point prevalence of life weariness and suicidal thoughts and their relationship with socio-demographic characteristics in a population of older adults in Sweden. METHOD Data from 7913 individuals aged 60 years and older were drawn from the Swedish National Study on Aging and Care, a collaborative study in Sweden. Life weariness and suicidal thoughts were measured by one item derived from the Montgomery-Åsberg Depression Rating Scale. A multinomial regression model was used to investigate the relationships of socio-demographic characteristics with life weariness and suicidal thoughts. RESULTS Living in urban and semi-urban areas, being of advanced age, being divorced and having lower educational levels were related to life weariness. Living in a residential care facility, being widowed or unmarried, being born in a non-Nordic European country and experiencing financial difficulties were related to both life weariness and suicidal thoughts. Sex was found to be unrelated to either life weariness or suicidal thoughts. CONCLUSION This study found that several socio-demographic variables were associated with life weariness and suicidal thoughts among older adults. Specific attention to older individuals with these characteristics may be warranted as they might be more vulnerable to life weariness and suicidal thoughts.

Abstract
In previous research we have learned that patients with chronic or complex diseases often experience difficulties when transitioning from hospital care to self-care in their home. We address these difficulties by developing an eHealth tool for patients - ePATH (electronic Patient Activation in Treatment at Home) - intended to empower each patient to manage their individual situation. We have employed a user-centered design process involving both patients and healthcare personnel to specify the content and functionality of ePATH. The system is deployed as a web application with secure login for patients. In this article, we describe the main content and functionality of the system that makes it possible for a patient to manage symptoms development in relation to treatment progression Interactive functionality, e.g., reminders and social support, is included to make the ePATH a useful and informative bridge between patients, next-of-kin and different caregivers. One lesson learned is that it is necessary to incorporate motivational components in the development of an eHealth tool to successfully overcome the "intention-behavior" gap. The self-determination theory of motivation can be used to ensure that important aspects are not missed.

The provision of accredited higher education on dementia in six European countries: An exploratory study. NURSE EDUCATION TODAY 2018; 60:161-169. [PMID: 29132018 DOI: 10.1016/j.nedt.2017.10.010] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/20/2017] [Revised: 09/22/2017] [Accepted: 10/19/2017] [Indexed: 06/07/2023]
Abstract
BACKGROUND The World Health Organization has identified developing the knowledge and skills of healthcare professionals who are involved in dementia care as a priority. Most healthcare professionals lack the necessary knowledge, skills and understanding to provide high quality dementia care. While dementia education amongst most UK university health and social care programmes is inconsistent, we know little about the provision of dementia education in European universities. OBJECTIVES To examine the provision of accredited higher education on dementia in European countries, to illustrate that it is highly variable despite universities being the major provider of education for healthcare professionals internationally. DESIGN An exploratory research design was used. SETTINGS The providers of higher education undergraduate and postgraduate programmes in the Czech Republic, Portugal, Scotland, Slovenia, Spain, Sweden. PARTICIPANTS Higher Education Institutions who provide undergraduate and postgraduate education in the fields of nursing, medicine, psychology, social work, physiotherapy, occupational therapy, and gerontology in six European countries. METHODS The data was collected using a structured questionnaire. Researchers in each country conducted an internet-based search using the websites of Higher Education Institutions to identify existing accredited dementia education. RESULTS These searches revealed a lack of dementia education in undergraduate health and social care study programmes. Three of the six countries offered postgraduate study programmes on dementia. There was a significant variation amongst the countries in relation to the provision of dementia education at undergraduate, postgraduate and doctoral levels. CONCLUSIONS Dementia is a global challenge and educating and upskilling the workforce is a policy imperative. To deliver the best dementia care, investment in interprofessional evidence-based education is required if we are to respond effectively and compassionately to the needs of people living with dementia and their families. Higher Education Institutions have an important role to play in equipping health and social care professionals with the knowledge, skills and understanding to respond to this imperative.

Abstract
OBJECTIVES To examine differences in growth patterns in preterm infants developing major morbidities including retinopathy of prematurity (ROP), bronchopulmonary dysplasia (BPD), necrotising enterocolitis (NEC) and intraventricular haemorrhage (IVH). STUDY DESIGN Cohort study of 2521 infants born at a gestational age (GA) of 23-30 weeks from 11 level III neonatal intensive care units in USA and Canada, and 3 Swedish population-based cohorts. OUTCOMES Birth weight and postnatal weight gain were examined relative to birth GA and ROP, BPD, NEC and IVH development. RESULTS Among infants with a birth GA of 25-30 weeks, birth weight SD score and postnatal weight were lower in those developing ROP and BPD. Infants developing ROP showed lower growth rates during postnatal weeks 7-9 in the 23-24 weeks GA group, during weeks 4-6 in the 25-26 weeks GA group and during weeks 1-5 in the 27-30 weeks GA group. Infants with BPD born at 27-30 weeks GA showed lower growth rates during postnatal weeks 3-5. Infants with NEC had lower growth rates after postnatal week 6 in all GA groups, with no significant differences in birth weight SD score. IVH was not associated with prenatal or postnatal growth. CONCLUSIONS In this cohort study of extremely preterm infants, we found that the postnatal growth pattern was associated with morbidities such as ROP, BPD and NEC as well as with gestational age at birth.

Abstract
This article presents an integrative literature review of the experience of dementia care associated with the extended palliative phase of dementia. The aim was to highlight how dementia is defined in the literature and describe what is known about the symptomatology and management of advanced dementia regarding the needs and preferences of the person with dementia and their family carer/s. There was no consistent definition of advanced dementia. The extended palliative phase was generally synonymous with end-of-life care. Advanced care planning is purported to enable professionals to work together with people with dementia and their families. A lack of understanding of palliative care among frontline practitioners was related to a dearth of educational opportunities in advanced dementia care. There are few robust concepts and theories that embrace living the best life possible during the later stages of dementia. These findings informed our subsequent work around the concept, ‘Dementia Palliare’.

Abstract
OBJECTIVES To describe three-year trends in nutritional status and sleep quality and their impact on hospital utilisation in the oldest old (80 +) with heart failure (HF). DESIGN Single-centred longitudinal observational study. SETTING South-eastern Sweden. PARTICIPANTS 90 elderly (80+) with objectively verified HF. MEASUREMENTS Baseline data from the Mini Nutritional Assessment (MNA) and on sleep quality were collected through structured interviews following the HF diagnosis (n=90) and at a three-year follow-up (n=41). Data on hospital utilisation during the three years following the HF diagnosis were also collected. RESULTS Nineteen percent of the participants were found to have impaired nutritional status, a condition that increased hospital utilisation by four bed days per year. A majority (85%) had impaired sleep quality, but no impact on hospital utilisation was found. Nutritional status and sleep quality were stable over the three-year period. CONCLUSION In the oldest old with HF, impaired nutritional status and impaired sleep quality are already common at HF diagnosis. Impaired nutritional status increases hospital utilisation significantly. Therefore, it is of supreme importance to systematically evaluate nutritional status and sleep quality in the oldest old when they are diagnosed with HF, as well as to take action if impairments are present.

Leg ulcers in older people: a national study addressing variation in diagnosis, pain and sleep disturbance. BMC Geriatr 2016; 16:25.

Abstract
BACKGROUND Leg ulcers commonly emerge as a symptom of other comorbidities, often in older people. As a consequence of the ulcer, pain and sleep disturbances might occur. Due to the complex illness, the responsibility of treatment is unclear between health caregivers. The interaction between ulcer type, sleep and pain has not previously been investigated. This study aimed to explore pain in older men and women (65 years and older) with different diagnoses of leg ulcers and to investigate the associations of sleep disturbances and pain in people with leg ulcer diagnosis. METHODS The study used a cross-sectional design and data from the Swedish Registry of Ulcer Treatment, collected between May 2009 and December 2013. One thousand and eight hundred and twenty four people were included, and 62.9% were women. The mean age was 83.4 years (SD 8.8). For the analyses, the chi-square test, Mann-Whitney U-test, t-test, one-way ANOVA and logistic regression was performed. Pain was measured by the Numeric Rating Scale (NRS), and sleep disturbances was assessed dichotomously. RESULTS We found the prevalence of pain intensity ≥ 5 on the NRS to be 34.8% in those reporting pain. Additionally, the pain intensity was associated with the number of ulcers (p = 0.003). Sleep disturbances were associated with pain (p < 0.001) and were found in 34.8% of the total sample. Although more women than men reported pain and scored higher on the NRS, no significant gender difference in sleep disturbances was found (p = 0.606). The mean NRS scores did not differ significantly between the ulcer types; however, arterial and venous-arterial ulcers increased the risk of sleep disturbances, as did higher pain scores. CONCLUSIONS The majority of the participants were of advanced age (>80 years) and frequently suffered from pain and sleep disturbances. Further research is needed regarding pain, sleep and wound healing in the oldest old with leg ulcers. Ulcer pain sometimes appears to receive less attention in ulcer management, as do sleep disturbances, implying that individual needs might not be satisfactorily met. National guidelines in managing leg ulcers, which also consider consequences such as sleep disturbances, pain and discomfort, are needed.

Abstract
AIMS Mineral deficiencies cause several health problems in the world, especially for populations consuming cereal-based diets rich in the anti-nutrient phytate. Our aim was to characterize the phytate-degrading capacity of the yeast Pichia kudriavzevii TY13 and its secretion of phytase. METHODS AND RESULTS The phytase activity in cell-free supernatants from cultures with 100% intact cells was 35-190 mU ml(-1) depending on the media. The Km was 0.28 mmol l(-1) and the specific phytase activity 0.32 U mg(-1) total protein. The phytase activity and secretion of extracellular non-cell-bound phytase was affected by the medium phosphate concentrations. Further, addition of yeast extract had a clearly inducing effect, resulting in over 60% of the cultures total phytase activity as non-cell-bound. CONCLUSIONS Our study reveals that it is possible to achieve high extracellular phytase activity from the yeast P. kudriavzevii TY13 by proper composition of the growth medium. SIGNIFICANCE AND IMPACT OF THE STUDY TY13 could be a promising future starter culture for fermented foods with improved mineral bioavailability. Using strains that secrete phytase to the food matrix may significantly improve the phytate degradation by facilitating the enzyme-to-substrate interaction. The secreted non-cell-bound phytase activities by TY13 could further be advantageous in industrial production of phytase.

Measurement properties of the minimal insomnia symptom scale as an insomnia screening tool for adults and the elderly. Sleep Med 2015; 16:379-84.

Abstract
BACKGROUND The psychometric properties of the three-item Minimal Insomnia Symptom Scale (MISS) were evaluated using the classical test theory. Different cut-offs for identifying insomnia were suggested in two age groups (≥6 and ≥7 among adult and elderly people, respectively). The aim of the present study was to test the measurement properties of the MISS using the Rasch measurement model, with special emphasis on differential item functioning by gender and age. METHODS Cross-sectional MISS data from adult (age 20-64 years, n = 1075) and elderly (age 65+, n = 548) populations were analysed using the Rasch measurement model. RESULTS Data generally met Rasch model requirements and the scale could separate between two distinct groups of people. Differential item functioning was found by age but not gender. The difference between the adult and elderly samples was lower for the originally recommended ≥6 points cut-off (0.09 logits) than for the ≥7 points cut-off (0.23 logits), but greater at the lower and higher ends of the scale. CONCLUSIONS This study provides general support for the measurement properties of the MISS. Caution should be exercised in comparing raw MISS scores between age groups, but applying a ≥6 cut-off appears to allow for valid comparisons between adults and the elderly regarding the presence of insomnia. Nevertheless, additional studies are needed to determine the clinically optimal cut-score for identification of insomnia.

Abstract
AIM To find predictors of abnormal retinal vascularisation in moderately to late preterm newborn infants considered to have no risk of developing retinopathy of prematurity. METHODS Seventy-eight infants (34 girls) were recruited from a longitudinal study of otherwise healthy premature children born at a gestational age of 32 + 0-36 + 6 weeks. Retinal vessel morphology was evaluated at mean postnatal age 7 days. Insulin-like growth factor-I (IGF-I) levels were analysed in umbilical cord blood. RESULTS Of the 78 infants, 21 (27%) had abnormal retinal vessel morphology; they had significantly lower median (range) birth weight [1850 g, (1190-3260), vs. 2320, (1330-3580), p < 0.0001], shorter birth length [43.0 cm, (38-49), vs. 46.0, (40-50), p < 0.0001] and smaller head circumference [31.0 cm, (27.7-34.0), vs. 32.0, (27.5-36.5), p = 0.003]. They also had significantly lower gestational age [34 + 1 weeks, (32 + 2-35 + 3), vs. 34 + 6, (32 + 2-36 + 6), p = 0.004] and mean ± SD IGF-I levels (24.6 ± 17.0 μg/L vs. 46.7 ± 21.5, p < 0.0001). A higher percentage of these infants were small for gestational age (57.1% vs. 15.8%, p = 0.001), and maternal hypertension/preeclampsia rates were also higher (47.6% vs. 19.3%, p = 0.03). Step-wise logistic regression showed that birth weight was the strongest predictor of abnormal retinal vascularisation (p < 0.0001, odds ratio 0.040, 95% confidence interval 0.007-0.216). CONCLUSION In this population of moderately to late preterm newborns, birth weight appeared to affect the retinal vascular system.

Abstract
BACKGROUND Premature infants are often stressed by the current retinopathy of prematurity (ROP) screening procedure. Additionally, only < 10 % of the screened infants will develop a ROP stadium requiring laser therapy. Therefore the present screening strategy is unsatisfactory. Furthermore, the current guidelines do not take into account postnatal factors. A new method considering postnatal factors is the weight, insulin-like growth factor, neonatal ROP (WINROP) algorithm. This approach is based on the early postnatal weight gain. The aim of this study was to assign the WINROP-algorithm to a preterm population in Switzerland and to analyze its ability for prediction. PATIENTS AND METHODS In this retrospective study, all preterm infants with a gestational age (GA) < 32 weeks and/or a birth weight (BW) ≤ 1500 g taken care of in the Department of Neonatology at the University Hospital Zurich from January 2003 to December 2008 were included. The weekly postnatal weight gain was analyzed by means of the modified WINROP-algorithm. RESULTS Altogether 376 preterm infants were analyzed. In 58 infants a "high-risk" alarm was released, thereof eight preterms developed a severe ROP and four of them needed laser therapy. CONCLUSIONS The high predictive value of the WINROP-algorithm was confirmed in our population of Swiss preterms. This instrument has the potential to simplify the current ROP screening procedure. Accordingly, the amount of ophthalmoscopies could be reduced significantly.

Abstract
OBJECTIVE The relationship between sleep complaints, comorbidity and health-related quality of life (HRQoL) in advanced age has not been clearly established. The aim of this study is therefore to investigate the presence of sleep complaints and discuss their association with morbidity and the HRQoL among the people aged 60 years and above. METHODS Data regarding demography, sleep, comorbidity and HRQoL were collected through questionnaires and interviews among 1128 people in Sweden. The Johns Hopkins adjusted clinical groups (ACG®) Case-Mix System 6.0 and the Short-Form Health Survey-12 were used to assess morbidity and HRQoL, respectively. RESULTS There was a divergence in the number of sleep complaints between those with no morbidity and those who had a high degree of comorbidity. Most of the sleep complaints related to low HRQoL were found among those with a high degree of comorbidity. CONCLUSIONS People with a high degree of comorbidity appear to be a group with a high risk of having both sleep complaints and a low HRQoL. Thus, this study suggests that even if sleep complaints appear to be difficult to identify and treat successfully, it is important to pay particular attention to those people who suffer from a high degree of comorbidity if their HRQoL is to be maintained.

Abstract
BACKGROUND Insomnia is common among elderly people and associated with poor health. The Minimal Insomnia Symptom Scale (MISS) is a three item screening instrument that has been found to be psychometrically sound and capable of identifying insomnia in the general population (20-64 years). However, its measurement properties have not been studied in an elderly population. Our aim was to test the measurement properties of the MISS among people aged 65 + in Sweden, by replicating the original study in an elderly sample. METHODS Data from a cross-sectional survey of 548 elderly individuals were analysed in terms of assumptions of summation of items, floor/ceiling effects, reliability and optimal cut-off score by means of ROC-curve analysis and compared with self-reported insomnia criteria. RESULTS Corrected item-total correlations ranged between 0.64-0.70, floor/ceiling effects were 6.6/0.6% and reliability was 0.81. ROC analysis identified the optimal cut-off score as ≥ 7 (sensitivity, 0.93; specificity, 0.84; positive/negative predictive values, 0.256/0.995). Using this cut-off score, the prevalence of insomnia in the study sample was 21.7% and most frequent among women and the oldest old. CONCLUSIONS Data support the measurement properties of the MISS as a possible insomnia screening instrument for elderly persons. This study make evident that the MISS is useful for identifying elderly people with insomnia-like sleep problems. Further studies are needed to assess its usefulness in identifying clinically defined insomnia.

Abstract
BACKGROUND Sleep disturbances are common problems among individuals in hospitals and institutions. Although several studies have explored this phenomenon, there is still a lack of knowledge about the effectiveness of sleep-promoting nursing interventions. This systematic review aims to describe and evaluate the effectiveness of sleep-promoting nursing interventions in health care settings. APPROACH A systematic review was performed. In June 2009, a literature search was carried out in the following databases: Academic Search Elite, CINAHL, the Cochrane Library and MedLine/PubMed. Fifty-two references were identified and after critical appraisal, nine studies were selected. A compilation of the results and the outcomes of the interventions were carried out. Furthermore, the evidence strength of the interventions was assessed. FINDINGS Little evidence for the nursing interventions, sleep hygiene, music, natural sound and vision, stimulation of acupoints, relaxation, massage and aromatherapy is found. However, large effect size of interventions were found when using massage, acupuncture and music, natural sounds or music videos. The use of sleep hygiene and relaxation, on the other hand, produced only small effects. CONCLUSION The lack of high evidence strength for the nursing interventions together with the uncertainty about their effects calls for more research before implementing these interventions into clinical practice.

Abstract
AIM To evaluate ophthalmological findings in children with Silver-Russell syndrome (SRS). METHODS An ophthalmological evaluation including visual acuity (VA), refraction, strabismus, near point of convergence (NPC), slit-lamp examination, ophthalmoscopy, axial length measurements and full-field electroretinogram was performed on 18 children with SRS (8 girls, 10 boys; mean age 11.6 years). Fundus photographs were taken for digital image analysis. Data were compared with data on an age- and gender-matched reference group (ref) of school children (n=99). RESULTS Seventeen out of 18 children with SRS had ophthalmological abnormalities. Best corrected VA of the best eye was <0.1 log of the minimal angle of resolution in 11 children (ref n=98) (p<0.0001), and 11 children had refractive errors (ref n=33) (p=0.05). Anisometropia (≥1 dioptre) was noted in three of the children (ref n=3) (p=0.046). Subnormal stereo acuity and NPC were found in 2/16 (ref=0) (p=0.02). The total axial length in both eyes was shorter compared with that in controls (p<0.006 and p<0.001). Small optic discs were found in 3/16, large cup in 3/16 and increased tortuosity of retinal vessels in 4/13 children with SRS. CONCLUSION Children with SRS, who are severely intrauterine growth retarded, show significant ophthalmological abnormalities. Based on the present findings, ophthalmological examination is recommended in children with SRS.

Abstract
AIM To evaluate the association between gestational age (GA), early and late postnatal growth variables and ophthalmologic outcome in ex-preterm children. methods: Children (GA < 32 weeks, n = 66), previously examined regarding insulin-like growth factor 1 (IGF-1) serum concentrations in relation to ROP, underwent ophthalmologic examination at median 5.6 years. Weight, height, and head circumference (HC) were measured and expressed as SDS. Growth variables were analysed in relation to ophthalmologic outcome. RESULTS At follow-up 74% had some ophthalmologic abnormality and 17% had visual impairment. Poor visual acuity was correlated with low GA (r(s) = 0.29, p = 0.019), low weight at 32 weeks (r(s) = 0.30, p = 0.013), and low weight (r(s) = 0.37, p = 0.0025), height (r(s) = 0.41, p = 0.0007) and HC (r(s) = 0.55, p < 0.0001) at follow-up. Hyperopic children (25%) had low neonatal IGF-1 (p = 0.0096) and HC at follow-up (p = 0.022). Poor visual perception was correlated with low early weight (r(s) = 0.38, p = 0.0036) and HC at follow-up (r(s) = 0.39, p = 0.0024). Head circumference at follow-up was correlated with GA (r(s) = 0.40, p = 0.0012), neonatal IGF-1 (r(s) = 0.37, p = 0.0031), and early weight (r(s) = 0.27, p = 0.035). CONCLUSIONS In very preterm children, early and later postnatal growth is closely related to visual acuity and perception at follow-up. In addition, IGF-1 concentrations and early growth are correlated with head circumference and refraction at follow-up.

Abstract
UNLABELLED Evidence is accumulating that one of the strongest predictors of retinopathy of prematurity (ROP), in addition to low gestational age, is poor weight gain during the first weeks of life. In infants born preterm, the retina is not fully vascularised. The more premature the child, the larger is the avascular area. In response to hypoxia, vascular endothelial growth factor (VEGF) is secreted. For appropriate VEGF-induced vessel growth, sufficient levels of insulin-like growth factor I (IGF-I) in serum are necessary. IGF-I is a peptide, related to nutrition supply, which is essential for both pre- and post-natal general growth as well as for growth of the retinal vasculature. In prematurely born infants, serum levels are closely related to gestational age and are lower in more prematurely born infants. At preterm birth the placental supply of nutrients is lost, growth factors are suddenly reduced and general as well as vascular growth slows down or ceases. In addition, the relative hyperoxia of the extra-uterine milieu, together with supplemental oxygen, causes a regression of already developed retinal vessels. Postnatal growth retardation is a major problem in very preterm infants. Both poor early weight gain and low serum levels of IGF-I during the first weeks/months of life have been found to be correlated with severity of ROP. CONCLUSION This review will focus on the mechanisms leading to ROP by exploring factors responsible for poor early weight gain and abnormal vascularisation of the eye of the preterm infant.

Abstract
OBJECTIVE To describe the visual functions and relate them to MRI findings and the intellectual level in adolescents born with very low birth weight (VLBW). DESIGN Population-based case-control study. PATIENTS 59 15-year-old VLBW adolescents and 55 sex and age-matched controls with normal birth weight. MAIN OUTCOME MEASURES Objective clinical findings (visual acuity, stereo acuity and cycloplegic refraction) were recorded. Structured history taking was used to identify visual difficulties. The intellectual level was assessed with the Wechsler Intelligence Scale for Children (WISC). All VLBW adolescents underwent MRI of the brain. RESULTS Significant differences were found between the VLBW adolescents and controls regarding visual acuity (median -0.11 and -0.2, respectively; p=0.004), stereo acuity (median 60'' and 30'', respectively; p<0.001), prevalence of astigmatism (11/58 and 0/55, respectively; p<0.001) and in full-scale IQ (mean IQ 85 and 97, respectively; p<0.001) and performance IQ (mean 87 and 99, respectively; p=0.002). The structured history also revealed a borderline significant difference between the groups (mean problems 0.46 and 0.15 respectively; p=0.051). 30% (17/57) of the VLBW adolescents had abnormal MRI findings and performed worse in all tests, compared with both the VLBW adolescents without MRI pathology and the normal controls. CONCLUSION This study confirms previous observations that VLBW adolescents are at a disadvantage regarding visual outcome compared with those with normal birth weight. In 47%, visual dysfunction was associated with abnormal MRI findings and in 33% with learning disabilities. The adolescents with abnormal MRI findings had more pronounced visual and cognitive dysfunction. The findings indicate a cerebral causative component for the visual dysfunction seen in the present study.

Abstract
AIMS To investigate visual function and ocular features in children with attention deficit hyperactivity disorder (AD/HD) and establish whether treatment with stimulants is reflected in functioning of the visual system. METHODS Detailed ophthalmologic evaluations without and with stimulants were performed in 42 children (37 boys) with AD/HD, mean age 12 years, and compared with a reference group (ref; n=50; mean age 11.9 years; 44 boys). For a comparison between two groups, Mann-Whitney's U-test was used for ordered and continuous variables; for dichotomous variables, Fisher's exact test was used. For paired comparison (with and without treatment), sign test was used. RESULTS In all, 83% had visual acuity of >0.8 (<0.1 logMAR) without treatment, 90% with stimulants (ref 98%; P=0.032 and n.s., respectively). Heterophoria was found in 29% without, and in 27% with, stimulants (ref 10%; P=0.038 and n.s., respectively) and subnormal stereovision (>60 s of arc) in 26% (ref 6%; P=0.016) without stimulants, and in 27%, with (P=0.014). Abnormal convergence (>6 cm or absent) was noted in 24% (ref 6%; P=0.031) without treatment and in 17%, with (n.s.). Astigmatism (> or =1.0 D) was observed in 24% (ref 6%; P=0.03), and signs of visuoperceptual problems in 21% (ref 2%; P=0.007). We found smaller optic discs (n=8/38) and neuroretinal rim areas (n=7/38) (P<0.0001) and decreased tortuosity of retinal arteries (n=6/34) (P=0.0002) than that of controls. CONCLUSIONS Children with AD/HD had a high frequency of ophthalmologic findings, which were not significantly improved with stimulants. They presented subtle morphological changes of the optic nerve and retinal vasculature, indicating an early disturbance of the development of these structures.

Abstract
AIMS To evaluate ophthalmological findings in children adopted from eastern Europe. METHODS A prospective study on 72/99 children, born 1990-5 and adopted from eastern Europe to western Sweden during 1993-7 was performed. The children (41 boys; mean age 7.5 years) were compared with an age and sex matched reference group ("ref") of Swedish children. RESULTS 78% of the adopted children had abnormal ocular findings. 26% (ref 4%) had visual acuity (VA) of the better eye < or = 0.5 (> or = 0.3 logMAR) (p = 0.0001) and 8% (ref 0%) were visually impaired (p = 0.01). Amblyopia was found in 15% (ref 2%) (p = 0.005). 22% (ref 10%) were hyperopic (> or = 2.0 D SE) (NS) and 10% (ref 1%) were myopic (> or = 0.5 D SE) (p = 0.03). Astigmatism (> or = 0.75 D) was found in 51% (ref 23%) (p = 0.004). 32% (ref 2%) had strabismus (p<0.0001), mostly esotropia. Four cases had bilateral optic nerve hypoplasia, in three of whom a history of suspected prenatal alcohol exposure was documented. One child had congenital glaucoma. Signs of visuoperceptual problems were recorded in 37% (ref 1%) (p<0.0001). CONCLUSION In this study, children adopted from eastern Europe had a high frequency of ophthalmological findings. Consequently, it is strongly recommended that an ophthalmological examination be performed in these children after arrival in their new home country.

Abstract
PURPOSE The aim of this study was to assess visual perception at school age of children born preterm with known lesions to the posterior visual pathways or with ophthalmologic signs that might indicate such lesions. METHODS The study group consisted of 91 patients born before the 37th gestational week. Visual perception was assessed using the TVPS-R (Test of Visual Perceptual Skills - Revised) and a structured interview. In addition, ophthalmologic and orthoptic examinations were performed. RESULTS On the test of visual perception, 67% of the patients had results below the third percentile of the American reference group. This is to be compared with 10% of Swedish full-term controls. Scores below the third percentile were observed in 87% of the patients with known brain lesions, 48% of those with strabismus without known brain lesion, and 86% of those with reduced visual acuity in the absence of strabismus and known brain lesion. CONCLUSIONS Reduced visual perception is common among children born preterm who have strabismus and/or reduced visual acuity, as well as in those with known brain lesions. This study emphasises the need to find tools to identify and assess those patients who have visual perceptual problems that may restrict their ability to meet the demands of daily life.

Abstract
AIMS To evaluate the relation between optic disc morphology and timing of periventricular white matter damage, defined as either periventricular leucomalacia (PVL) or periventricular haemorrhage (PVH), as estimated by neuroradiology. METHODS 35 children with periventricular white matter damage who had had neuroradiology performed and ocular fundus photographs taken had their photographs analysed by digital image analysis and compared with a control group of 100 healthy full term children. Timing of brain lesion was estimated by analysis of the brain lesion pattern on neuroradiological examinations (magnetic resonance imaging or computed tomography). RESULTS Four of 35 children had a small optic disc area; these four children had a brain lesion estimated to have occurred before 28 weeks of gestation. Nine of 11 children with a large cup area had a PVL/PVH estimated to have occurred after 28 weeks of gestation. The children with PVL/PVH had a significantly larger cup area (median 0.75 mm(2)) than the control group (median 0.33 mm(2)) (p = 0.001) and a significantly smaller neuroretinal rim area (median 1.58 mm(2)) than the controls (median 2.07 mm(2)) (p = 0.001). CONCLUSION In a child with PVL/PVH and abnormal optic disc morphology, the possibilities of timing of the lesion should be considered.

Abstract
AIM To investigate associated neurological, endocrinological and cognitive dysfunctions in children with visual impairment caused by optic nerve hypoplasia or optic nerve/fundus coloboma and/or microphthalmus. METHODS Forty children born between 1990 and 1998 were assessed by neurological examination, re-evaluation of neuroradiological investigations, review of medical records and examination of cognitive levels. RESULTS Neurological dysfunctions (epilepsy and/or motor impairment) were found in 13/28 children with optic nerve hypoplasia and in 3/12 children with coloboma/microphthalmus. The optic pathways were thin in 22/24, an abnormal posterior pituitary gland and/or thin infundibulum was found in 16/22 and absence of septum pellucidum in 14/27 children with optic nerve hypoplasia. Other types of cerebral abnormalities occurred in 9/26 children. Among children with coloboma/microphthalmus, the optic pathways were thin in 4/8 children but none had pituitary or cerebral midline abnormalities. Sixteen children with optic nerve hypoplasia were receiving hormone substitution but none of the children with coloboma/microphthalmus. Thirteen of the 16 children with optic nerve hypoplasia and with an abnormal pituitary region had endocrinological deficiencies. Mental retardation was found in 9/24 of the children with optic nerve hypoplasia and in 5/10 of the children with coloboma/microphthalmus. CONCLUSION Endocrinological. neurological and neuroradiological defects seem more common in children with optic nerve hypoplasia than in children with coloboma. A pituitary region that appears abnormal in magnetic resonance imaging seems to predict endocrinological deficits in children with optic nerve hypoplasia.

Abstract
AIM To compare and evaluate a mini-knemometer with a simple and inexpensive electronic caliper with regard to precision, handling error (technical error) and estimation of growth velocity. METHODS Thirty-five prematurely born infants, with a median gestational age of 29 (range 24-33) wk and a median birthweight of 960 (range 480-2,480) g, were measured on 409 different occasions with both instruments. On each occasion, five independent readings were made. RESULTS There was no significant difference in precision between the two instruments, when measuring growth velocity over a 4 wk period (median 0.41, range 0.10-0.59 mm d(-1)). The handling error in this study, calculated as the mean standard deviation, was 0.36 (SD 0.18, coefficient of variation 0.38%) mm for the simple electronic caliper and 0.59 mm for the mini-knemometer. Short-term growth was detectable within 2 d when growth velocity was normal. CONCLUSION Longitudinal measurement of lower leg length is a gentle and useful complementary method for assessing growth in preterm infants. An inexpensive electronic caliper is well suited for routine use in clinical practice, with measurements taken once or twice a week.

Abstract
AIM To assess cognitive ability in a population-based group of prematurely born school-aged children and to relate these findings to postnatal morbidity. METHOD The study group consisted of a cohort of 51 children born preterm, 43 (26 boys, 17 girls) of whom were available for psychological evaluation At evaluation, their median age was 10 y (range 8-11 y). They were all born between 1988 and 1991, with gestational age less than 29 wk (median 27, range 24-28). Their median birthweight was 1060g (range 450-1450). The Wechsler Intelligence Scale for Children (WISC-III) was used, and the test results were compared with those of a standardized, age-matched, normative group of children. RESULTS Thirteen children (30%) performed below average [intelligence quotient (IQ) < 80] for Full Scale IQ (FSIQ). Thirty-six children had a Verbal IQ (VIQ) below the mean value of 100 [84%, 95% confidence interval 73-95%], p < 0.0001. The Performance IQ (PIQ) was within the expected range of a normal population, although a large variability was observed. Discrepancies between VIQ and PIQ of more than 15 IQ units were found in 42% of the children. High postnatal morbidity (days with assisted ventilation, number of blood transfusions) and low birthweight standard deviation scores (SDS) were associated with lower PIQ than VIQ, while low postnatal morbidity and high birthweight were associated with higher PIQ than VIQ. CONCLUSION This cohort of preterm children had reduced overall verbal capacity independent of morbidity, and a large variability in performance capacity that was associated with postnatal morbidity. The findings suggest that there are different mechanisms influencing the outcome of verbal and performance capacity in preterm children.

Abstract
UNLABELLED The aim of this study was to investigate whether birth size is associated with permanent renal damage in children with urinary tract infection (UTI). A cohort of 1221 children under 16 y of age was diagnosed with their first symptomatic UTI between 1970 and 1979. Of these, 74 had urographic renal scarring in childhood and 57 were re-examined as adults. The birth files of 48 of these patients (35F, 13M) were available, and birthweight and birthlength in relation to gestational age were analysed and compared with a Swedish reference population. Children who had renal damage without vesicoureteric reflux were significantly smaller at birth (median weight, -0.76 SDS) compared with both children who had renal damage and reflux (median weight, -0.01 SDS) and the reference population. CONCLUSION The demonstration of low birthweight among children with UTI and renal damage but no reflux suggests that low birthweight may be a risk factor for the development of renal damage.

Abstract
PURPOSE To characterise the nature and degree of ocular disorders and cerebral morphological and functional abnormalities in a population-based group of visually impaired full-term pre-school children. METHODS Forty-five children who were born at full-term between 1989 and 1995 in Värmland, Sweden, were reported as being visually impaired. An ophthalmological examination was performed and clinical data regarding mental development and neurological disease were obtained for all children. Cerebral imaging was performed in 35 children. RESULTS Twenty-six per cent of the children were found to have ocular disorders only. Forty-two per cent had cerebral morphological abnormalities, verified by cerebral imaging, and 65% had signs of cerebral functional abnormalities. In total, 74% were found to have cerebral morphological and/or cerebral functional abnormalities. CONCLUSION The majority of children with visual impairment, including children with ocular disorders, were found to have cerebral morphological and/or cerebral functional abnormalities. We suggest that any child with visual impairment should therefore undergo cerebral imaging and be examined by a paediatrician in order to establish the correct diagnosis.

Abstract
The data in this article are based on investigations performed in 25 children with suspected septo-optic dysplasia (SOD). There are many signs and methods that help in the diagnosis of SOD. In particular, the ocular fundus, abnormalities of the hypothalamo-pituitary axis and other midline brain structures should be described. In order to achieve a more holistic and functional diagnosis, the degree of neurological, neuropsychiatric and psychological involvement should also be stated. It has been suggested that SOD is associated with autosomal recessive inheritance, and it can be speculated that it is the result of genetic and environmental influences early in gestation. An early diagnosis can favourably influence the outcome of the affected child.
