Integrated care prevents hospitalisations for exacerbations in COPD patients

Hospital admissions due to chronic obstructive pulmonary disease (COPD) exacerbations have a major impact on the disease evolution and costs. The current authors postulated that a simple and well-standardised, low-intensity integrated care intervention can be effective to prevent such hospitalisations. Therefore, 155 exacerbated COPD patients (17% females) were recruited after hospital discharge from centres in Barcelona (Spain) and Leuven (Belgium). They were randomly assigned to either integrated care (IC; n = 65; age mean±sd 70±9 yrs; forced expiratory volume in one second (FEV1) 1.1±0.5 L, 43% predicted) or usual care (UC; n = 90; age 72±9 yrs; FEV1 1.1±0.05 L, 41% pred). The IC intervention consisted of an individually tailored care plan upon discharge shared with the primary care team, as well as accessibility to a specialised nurse case manager through a web-based call centre. After 12 months’ follow-up, IC showed a lower hospitalisation rate (1.5±2.6 versus 2.1±3.1) and a higher percentage of patients without re-admissions (49 versus 31%) than UC without differences in mortality (19 versus 16%, respectively). In conclusion, this trial demonstrates that a standardised integrated care intervention, based on shared care arrangements among different levels of the system with support of information technologies, effectively prevents hospitalisations for exacerbations in chronic obstructive pulmonary disease patients.

Home hospitalisation of exacerbated chronic obstructive pulmonary disease patients

It was postulated that home hospitalisation (HH) of selected chronic obstructive pulmonary disease (COPD) exacerbations admitted at the emergency room (ER) could facilitate a better outcome than conventional hospitalisation. To this end, 222 COPD patients (3.2% female; 71±10 yrs (mean±sd)) were randomly assigned to HH (n=121) or conventional care (n=101). During HH, integrated care was delivered by a specialised nurse with the patients free-phone access to the nurse ensured for an 8‐week follow-up period. Mortality (HH: 4.1%; controls: 6.9%) and hospital readmissions (HH: 0.24±0.57; controls: 0.38±0.70) were similar in both groups. However, at the end of the follow-up period, HH patients showed: 1) a lower rate of ER visits (0.13±0.43 versus 0.31±0.62); and 2) a noticeable improvement of quality of life (Δ St Georges Respiratory Questionnaire (SGRQ), −6.9 versus −2.4). Furthermore, a higher percentage of patients had a better knowledge of the disease (58% versus 27%), a better self-management of their condition (81% versus 48%), and the patients satisfaction was greater. The average overall direct cost per HH patient was 62% of the costs of conventional care, essentially due to fewer days of inpatient hospitalisation (1.7±2.3 versus 4.2±4.1 days). A comprehensive home care intervention in selected chronic obstructive pulmonary disease exacerbations appears as cost effective. The home hospitalisation intervention generates better outcomes at lower costs than conventional care.

Telemedicine Experience for Chronic Care in COPD

Information and telecommunication technologies are called to play a major role in the changes that healthcare systems have to face to cope with chronic disease. This paper reports a telemedicine experience for the home care of chronic patients suffering from chronic obstructive pulmonary disease (COPD) and an integrated system designed to carry out this experience. To determine the impact on health, the chronic care telemedicine system was used during one year (2002) with 157 COPD patients in a clinical experiment; endpoints were readmissions and mortality. Patients in the intervention group were followed up at their homes and could contact the care team at any time through the call center. The care team shared a unique electronic chronic patient record (ECPR) accessible through the web-based patient management module or the home visit units. Results suggest that integrated home telemedicine services can support health professionals caring for patients with chronic disease, and improve their health. We have found that simple telemedicine services (ubiquitous access to ECPR, ECPR shared by care team, accessibility to case manager, problem reporting integrated in ECPR) can increase the number of patients that were not readmitted (51% intervention, 33% control), are acceptable to professionals, and involve low installation and exploitation costs. Further research is needed to determine the role of telemonitoring and televisit services for this kind of patients

The impact of home hospitalization on healthcare costs of exacerbations in COPD patients

Home-hospitalization (HH) improves clinical outcomes in selected patients with chronic obstructive pulmonary disease (COPD) admitted at the emergency room due to an exacerbation, but its effects on healthcare costs are poorly known. The current analysis examines the impact of HH on direct healthcare costs, compared to conventional hospitalizations (CH). A randomized controlled trial was performed in two tertiary hospitals in Barcelona (Spain). A total of 180 exacerbated COPD patients (HH 103 and CH 77) admitted at the emergency room were studied. In the HH group, a specialized respiratory nurse delivered integrated care at home. The average direct cost per patient was significantly lower for HH than for CH, with a difference of 810€ (95% CI, 418–1,169€) in the mean cost per patient. The magnitude of monetary savings attributed to HH increased with the severity of the patients considered eligible for the intervention.

Recomendaciones sobre la atención al final de la vida en pacientes con EPOC

Over the last 20 years, advances in the treatment of patients with chronic obstructive pulmonary disease (COPD) have improved survival even among patients in the most advanced stages of the disease, such as those requiring domiciliary oxygen therapy. This improvement—in principle a positive development—has given rise to considerable clinical problems associated with the establishment of a therapeutic ceiling and the di culty of determining prognosis in some of these patients. in this situation, the clinician should consider introducing palliative care, that is, care aimed at improving symptom control, communication, physical activity, and emotional support, in order to achieve the best possible quality of life for the patient. Palliative care is generally associated with the advanced stages of a disease’s natural history, but in the case of COPD it is important to emphasize it does not necessarily mean that death is imminent. The lack of a generally accepted deinition for “end-stage COPD” makes it di cult to compare studies. Table 1 deines the basic concepts. improving the management of advanced-stage COPD not only has a direct impact on the quality of care received by the patient, but also has a positive effect on the health care system as a whole in that it reduces hospital admissions shifts the burden of care from the hospital to the community, and reduces unnecessary and unscheduled admissions to intensive care units. Many patients with COPD remain undiagnosed, and some of those diagnosed do not fulill the accepted criteria, and it is therefore extremely di cult to establish how many patients actually have very severe COPD, though it is estimated that the proportion may range between 3% and 15% of the total. The concern with broadening the clinician’s approach beyond actions taken primarily to prolong the patient’s life has developed more recently in the context of COPD in comparison with other diseases. nonetheless, and despite the lack of precise deinitions and the unpredictability of this disease, this broader approach should be an indispensable component of good practice in pulmonology. figure 1 summarizes the inal stages of life in patients with COPD.

Seasonality, ambient temperatures and hospitalizations for acute exacerbation of COPD: a population-based study in a metropolitan area

Background Excluding the tropics, exacerbations of chronic obstructive pulmonary disease (COPD) are more frequent in winter. However, studies that directly relate hospitalizations for exacerbation of COPD to ambient temperature are lacking. The aim of this study was to assess the influence of temperature on the number of hospitalizations for COPD. Methods This was a population-based study in a metropolitan area. All hospital discharges for acute exacerbation of COPD during 2009 in Barcelona and its metropolitan area were analyzed. The relationship between the number of hospitalizations for COPD and the mean, minimum, and maximum temperatures alongside comorbidity, humidity, influenza rate, and environmental pollution were studied. Results A total of 9,804 hospitalization discharges coded with COPD exacerbation as a primary diagnosis were included; 75.4% of cases were male with a mean age of 74.9±10.5 years and an average length of stay of 6.5±6.1 days. The highest number of admissions (3,644 [37.2%]) occurred during winter, followed by autumn with 2,367 (24.1%), spring with 2,347 (23.9%), and summer with 1,446 (14.7%; P<0.001). The maximum, minimum, and mean temperatures were associated similarly with the number of hospitalizations. On average, we found that for each degree Celsius decrease in mean weekly temperature, hospital admissions increased by 5.04% (r2=0.591; P<0.001). After adjustment for humidity, comorbidity, air pollution, and influenza-like illness, only mean temperatures retained statistical significance, with a mean increase of 4.7% in weekly admissions for each degree Celsius of temperature (r2=0.599, P<0.001). Conclusion Mean temperatures are closely and independently related to the number of hospitalizations for COPD.

The importance of knowing the home conditions of patients receiving long-term oxygen therapy

Purpose Long-term oxygen therapy (LTOT) is one of the main treatments for patients with chronic obstructive pulmonary disease. Patients receiving LTOT may have less than optimal home conditions and this may interfere with treatment. The objective of this study was, through home visits, to identify the characteristics of patients receiving LTOT and to develop knowledge regarding the home environments of these patients. Methods Ninety-seven patients with a mean age of 69 plus or minus 10.5 years were evaluated. This study was a cross-sectional descriptive analysis. Data were collected during an initial home visit, using a questionnaire standardized for the study. The results were analyzed retrospectively. Results Seventy-five percent of the patients had chronic obstructive pulmonary disease, and 11% were active smokers. The patients’ mean pulse oximetry values were 85.9% plus or minus 4.7% on room air and 92% plus or minus 3.9% on the prescribed flow of oxygen. Most of the patients did not use the treatment as prescribed and most used a humidifier. The extension hose had a mean length of 5 plus or minus 3.9 m (range, 1.5–16 m). In the year prior to the visit, 26% of the patients received emergency medical care because of respiratory problems. Few patients reported engaging in leisure activities. Conclusion The home visit allowed us to identify problems and interventions that could improve the way LTOT is used. The most common interventions related to smoking cessation, concentrator maintenance and cleaning, use of a humidifier, and adjustments of the length of the connector hose. Therefore, the home visit is a very important tool in providing comprehensive care to patients receiving LTOT, especially those who show lack of adequate progress and those who show uncertainty about the treatment method.

An adaptive case management system to support integrated care services

BACKGROUND Extensive deployment and sustainability of integrated care services (ICS) constitute an unmet need to reduce the burden of chronic conditions. The European Union project NEXES (2008-2013) assessed the deployment of four ICS encompassing the spectrum of severity of chronic patients. OBJECTIVE The current study aims to (i) describe the open source Adaptive Case Management (ACM) system (Linkcare®) developed to support the deployment of ICS at the level of healthcare district; (ii) to evaluate its performance; and, (iii) to identify key challenges for regional deployment of ICS. METHODS We first defined a conceptual model for ICS management and execution composed of five main stages. We then specified an associated logical model considering the dynamic runtime of ACM. Finally, we implemented the four ICS as a physical model with an ICS editor to allow professionals (case managers) to play active roles in adapting the system to their needs. Instances of ICS were then run in Linkcare®. Four ICS provided a framework for evaluating the system: Wellness and Rehabilitation (W&R) (number of patients enrolled in the study (n)=173); Enhanced Care (EC) in frail chronic patients to prevent hospital admissions, (n=848); Home Hospitalization and Early Discharge (HH/ED) (n=2314); and, Support to remote diagnosis (Support) (n=7793). The method for assessment of telemedicine applications (MAST) was used for iterative evaluation. RESULTS Linkcare® supports ACM with shared-care plans across healthcare tiers and offers integration with provider-specific electronic health records. Linkcare® successfully contributed to the deployment of the four ICS: W&R facilitated long-term sustainability of training effects (p<0.01) and active life style (p<0.03); EC showed significant positive outcomes (p<0.05); HH/ED reduced on average 5 in-hospital days per patient with a 30-d re-admission rate of 10%; and, Support, enhanced community-based quality forced spirometry testing (p<0.01). Key challenges for regional deployment of personalized care were identified. CONCLUSIONS Linkcare® provided the required functionalities to support integrated care adopting an ACM model, and it showed adaptive potential for its implementation in different health scenarios. The research generated strategies that contributed to face the challenges of the transition toward personalized medicine for chronic patients.

Recommendations for End-of-Life Care in Patients With Chronic Obstructive Pulmonary Disease

Over the last 20 years, advances in the treatment of patients with chronic obstructive pulmonary disease (COPD) have improved survival even among patients in the most advanced stages of the disease, such as those requiring domiciliary oxygen therapy.1,2 This improvement—in principle a positive development—has given rise to considerable clinical problems associated with the establishment of a therapeutic ceiling and the difficulty of determining prognosis in some of these patients. In this situation, the clinician should consider introducing palliative care, that is, care aimed at improving symptom control, communication, physical activity, and emotional support, in order to achieve the best possible quality of life for the patient. Palliative care is generally associated with the advanced stages of a disease’s natural history, but in the case of COPD it is important to emphasize it does not necessarily mean that death is imminent. The lack of a generally accepted definition for “end-stage COPD” makes it difficult to compare studies.3 Table 1 defines the basic concepts. Improving the management of advanced-stage COPD not only has a direct impact on the quality of care received by the patient, but also has a positive effect on the health care system as a whole in that it reduces hospital admissions shifts the burden of care from the hospital to the community, and reduces unnecessary and unscheduled admissions to intensive care units.4 Many patients with COPD remain undiagnosed, and some of those diagnosed do not fulfill the accepted criteria, and it is therefore extremely difficult to establish how many patients actually have very severe COPD, though it is estimated that the proportion may range between 3% and 15% of the total.5,6 The concern with broadening the clinician’s approach beyond actions taken primarily to prolong the patient’s life has developed more recently in the context of COPD in comparison with other diseases. Nonetheless, and despite the lack of precise definitions and the unpredictability of this disease, this broader approach should be an indispensable component of good practice in pulmonology.

Effectiveness of community-based integrated care in frail COPD patients: a randomised controlled trial.

Background:Chronic obstructive pulmonary disease (COPD) generates a high burden on health care, and hospital admissions represent a substantial proportion of the overall costs of the disease. Integrated care (IC) has shown efficacy to reduce hospitalisations in COPD patients at a pilot level. Deployment strategies for IC services require assessment of effectiveness at the health care system level.Aims:The aim of this study was to explore the effectiveness of a community-based IC service in preventing hospitalisations and emergency department (ED) visits in stable frail COPD patients.Methods:From April to December 2005, 155 frail community-dwelling COPD patients were randomly allocated either to IC (n=76, age 73 (8) years, forced expiratory volume during the first second, FEV1 41(19) % predicted) or usual care (n=84, age 75(9) years, FEV1 44 (20) % predicted) and followed up for 12 months. The IC intervention consisted of the following: (a) patient’s empowerment for self-management; (b) an individualised care plan; (c) access to a call centre; and (d) coordination between the levels of care. Thereafter, hospital admissions, ED visits and mortality were monitored for 6 years.Results:IC enhanced self-management (P=0.02), reduced anxiety–depression (P=0.001) and improved health-related quality of life (P=0.02). IC reduced both ED visits (P=0.02) and mortality (P=0.03) but not hospital admission. No differences between the two groups were seen after 6 years.Conclusion:The intervention improved clinical outcomes including survival and decreased the ED visits, but it did not reduce hospital admissions. The study facilitated the identification of two key requirements for adoption of IC services in the community: appropriate risk stratification of patients, and preparation of the community-based work force.
