Yes / The increasing prevalence and associated cost of treating chronic obstructive pulmonary disease (COPD) is unsustainable. Health care organizations are focusing on ways to support self-management and prevent hospital admissions, including telehealth-monitoring services capturing physiological and health status data. This paper reports on data captured during a pilot randomized controlled trial of telehealth-supported care within a community-based service for patients discharged from hospital following an exacerbation of their COPD. The aim was to undertake the first analysis of system data to determine whether telehealth monitoring can identify an exacerbation of COPD, providing clinicians with an opportunity to intervene with timely treatment and prevent hospital readmission. Methods: A total of 23 participants received a telehealth-supported intervention. This paper reports on the analysis of data from a telehealth monitoring system that captured data from two sources: (1) data uploaded both manually and using Bluetooth peripheral devices by the 23 participants and (2) clinical records entered as nursing notes by the clinicians. Rules embedded in the telehealth monitoring system triggered system alerts to be reviewed by remote clinicians who determined whether clinical intervention was required. We also analyzed data on the frequency and length (bed days) of hospital admissions, frequency of hospital Accident and Emergency visits that did not lead to hospital admission, and frequency and type of community health care service contacts—other than the COPD discharge service—for all participants for the duration of the intervention and 6 months postintervention. Results: Patients generated 512 alerts, 451 of which occurred during the first 42 days that all participants used the equipment. Patients generated fewer alerts over time with typically seven alerts per day within the first 10 days and four alerts per day thereafter. They also had three times more days without alerts than with alerts. Alerts were most commonly triggered by reports of being more tired, having difficulty with self-care, and blood pressure being out of range. During the 8-week intervention, and for 6-month follow-up, eight of the 23 patients were hospitalized. Hospital readmission rates (2/23, 9%) in the first 28 days of service were lower than the 20% UK norm. Conclusions: It seems that the clinical team can identify exacerbations based on both an increase in alerts and the types of system-generated alerts as evidenced by their efforts to provided treatment interventions. There was some indication that telehealth monitoring potentially delayed hospitalizations until after patients had been discharged from the service. We suggest that telehealth-supported care can fulfill an important role in enabling patients with COPD to better manage their condition and remain out of hospital, but adequate resourcing and timely response to alerts is a critical factor in supporting patients to remain at home. / This project was funded by the National Institute for Health Collaboration for Leadership in Applied Health Research and Care Yorkshire and Humber (CLAHRC YH).

Bakgrund: Astma och KOL är två vanlig kroniska sjukdomar som är kopplade till stort sjukdomslidande och lägre livskvalité. Många personer som idag lever med sjukdomarna lever isolerat från andra. Idag har vi en ständig utveckling av sociala nätverk som öppnar en ny möjlighet för egenvård. Egenvård kan göra att patienter får en bättre vardag samt att det lättare kan få ett socialt umgänge. Syfte: Syftet är sammanställa befintlig litteratur och där undersöka hur informations- och kommunikationsteknologi underlättar egenvården för patienter med astma och KOL. Metod: Litteraturstudie där artiklarna söktes i databaser för omvårdnadsvetenskap så som Web Of Science, pubmed och Cinahl. Litteraturstudien baseras på 16 vetenskapliga artiklar som både är kvalitativa och kvantitativa. Artiklarna som valdes är inte äldre än 10 år gamla, skrivna på engelska och publicerade i en vetenskaplig tidning. Resultat: Resultatet som artiklarna påvisade är grundade på IKT i form av datorer, mobiltelefoner, surfplattor och web-baserad program. Artiklarna visar att egenvården kan förbättras genom ökad livskvalité, bättre kommunikation och bättre sjukdomsinsikt när man använder IKT. Slutsats: IKT är en viktig roll i våran hälso- och sjukvård idag. Det finns dock liten forskning på hur egenvården kring astma och KOL påverkas av IKT. Den forskning som finns pekar åt är att den förbättrar för patienter. Det behövs även mer forskning kring IKT som en resurs för egenvård kring ett omvårdnadsperspektiv. / Introduktion: Asthma and COPD are two common chronic diseases that are linked to major suffering and reduced quality of life. Many people who live with the disease are isolated from others. Today we have a continuous development of social networks that opens a new opportunity for self-care. Self-care can make patients get a more normal life style and that it is easier to get a social life. Aim: The aim is to compile existing literature and of wich explore how information and communications technology facilitates selfcare for patients with asthma and COPD. Methods: Literaturestudy where the articles were searched in databases of nursing such as Web of Science, PubMed and Cinahl. The literature review based on 16 scientific articles that are both qualitative and quantitative. The articles selected are not older than 10 years, written in english and published in a scientific journal. Results: The results that the articles showed are based on ICT in the form of computers, cell phones, tablets, and web-based programs. Articles show self-care can be improved through increased quality of life, better communication and a better understanding of illness when using ICT. Conclusion: ICT play an important role in our health care today. However, there is little research on how self-care while suffering from asthma and COPD is influenced by ICT. The research is pointing to the improvements for patients. It also needed more research around ICT, self-care and from a nursing perspective.

Bakgrund: Kronisk obstruktiv lungsjukdom (KOL) är kronisk luftrörs/lungsjukdom. World Health Organisation [WHO] informerar att KOL kommer bli den tredje största dödsorsaken globalt och 3 miljoner människor har dött på grund av KOL år 2012 i världen och samtidigt sjukdomen har ökat bland kvinnor. Syfte: Syftet med studien var att belysa upplevelserna av att leva med KOL hos kvinnor. Metod: En litteraturstudie baserad på sju vetenskapliga, kvalitativa artiklar. I de inkluderade artiklarna kunde man läsa om kvinnors upplevelser. Artiklar analyserades utifrån beskrivning av allmän textanalys. Resultat: Resultat presenterades i följande tre kategorier, upplevelser av fysiska svårigheter och begräsningar såsom förlorat styrka att göra vardagliga saker, att vara begränsad till sitt rum, begränsad aktiviteter och sömn svårigheter. Upplevelser av oro och rädsla såsom om att bli andfådd, att dö i sömnen eller att andningstekniken inte ska fungera. Upplevelser av skuldkänslor relaterad till rökning, att man sätter skulden på myndigheterna då man inte fick information om konsekvenserna. Slutsats: Patienter med sjukdomen KOL kan uppleva begränsningar i vardagen på grund av sjukdomen. Deras sociala liv kan också påverkas då de ofta blir bundna till sina hem. Det kan man påstå att det behövs vidare forskning. / Background: Chronic obstructive pulmonary disease (COPD) is a chronic bronchial/pulmonary disease. World Health Organisation (WHO) informs that COPD will become the third largest cause of death globally and 3 million people have died due to this disease in the year 2012 in world and same time this disease have increased among women. Aim: The aim of this study was to examine the experiences of women living with COPD disease. Method: A general literature review was performed based on seven scientific qualitative articles. The included articles were about women´s experiences. Analysis of the selected qualitative studies was performed by a general text analysis. Results: The result was presented in three categories. The first category was about experiences of physical difficulties and limitations that dealt loss of the strength to do daily life things, being confined to own room or house, limited activities in and outside of house and insomnia. The second category was about experiences of anxiety and fear of being short of breath, dying in sleep and breathing techniques failure. Third category dealt with experiences of Guilt related to smoking, blaming authorities that they did not given information about consequences of smoking. Conclusion: Patients with COPD may experience limitations in daily life because of the disease. Their daily life can also be affected as they are often confined to their homes. It may be argued that it is needed further research.

This is a foundational study that applies Receiver Operating Characteristic (ROC) analysis to the evaluation of a chronic disease model that utilizes Remote Monitoring (RM) devices to identify clinical deterioration in a Chronic Obstructive Pulmonary Disease (COPD) population. Background: RM programmes in Disease Management (DM) are proliferating as one strategy to address management of chronic disease. The need to validate and quantify evidence-based value is acute. There is a need to apply new methods to better evaluate automated RM systems. ROC analysis is an engineering approach that has been widely applied to medical programmes but has not been applied to RM systems. Evaluation of classifiers, determination of thresholds and predictive accuracy for RM systems have not been evaluated using ROC analysis. Objectives: (1) apply ROC analysis to evaluation of a RM system; (2) analyse the performance of the model when applied to patient outcomes for a COPD population; (3) identify predictive classifier(s); (4) identify optimal threshold(s) and the predictive capacity of the classifiers. Methods: Parametric and non-parametric methods are utilized to determine accuracy, sensitivity, specificity and predictive capacity of classifiers Saturated Peripheral Oxygen (SpO2), Blood Pressure (BP), Pulse Rate (PR) based on event-based patient outcomes that include hospitalisation (IP), accident & emergency (A&E) and home visits (HH). Population: Patients identified with a primary diagnosis of COPD, monitored for a minimum of 183 days with at least one episode of in-patient (IP) hospitalisation for COPD in the 12 months preceding the monitoring period. Data Source: A subset of retrospective de-identified patient data from an NHS Direct evaluation of a COPD RM programme. Subsets utilized include classifiers, biometric readings, alerts generated by the system and resource utilisation. Contribution: Validates ROC methodology, identifies classifier performance and optimal threshold settings for the classifier, while making design recommendations and putting forth the next steps for research. The question answered by this research is that ROC analysis can provide additional information on the predictive capacity of RM systems. Justification of benefit: The results can be applied when evaluating health services and planning decisions on the costs and benefits. Methods can be applied to system design, protocol development, work flows and commissioning decisions based on value and benefit. Conclusion: Results validate the use of ROC analysis as a robust methodology for DM programmes that use RM devices to evaluate classifiers, thresholds and identification of the predictive capacity as well as identify areas where additional design may improve the predictive capacity of the model.
