Outcomes of a telemonitoring-based program (telEPOC) in frequently hospitalized COPD patients Does Home Telemonitoring after Pulmonary Rehabilitation Reduce Healthcare Use in Optimized COPD?? A Pilot Randomized Trial
Rationale : Early detection of chronic obstructive pulmonary disease ( COPD ) exacerbations using telemonitoring of physiological variables might reduce the frequency of hospitalization . Objectives : To evaluate the efficacy of home monitoring of lung mechanics by the forced oscillation technique and cardiac parameters in older patients with COPD and comorbidities . Methods : This multicenter , r and omized clinical trial recruited 312 patients with Global Initiative for Chronic Obstructive Lung Disease grade s II to IV COPD ( median age , 71 yr [ interquartile range , 66‐76 yr ] ; 49.6 % grade II , 50.4 % grade s III‐IV ) , with a history of exacerbation in the previous year and at least one nonpulmonary comorbidity . Patients were r and omized to usual care ( n = 158 ) or telemonitoring ( n = 154 ) and followed for 9 months . All telemonitoring patients self‐assessed lung mechanics daily , and in a subgroup with congestive heart failure ( n = 37 ) cardiac parameters were also monitored . An algorithm identified deterioration , triggering a telephone contact to determine appropriate interventions . Measurements and Main Results : Primary outcomes were time to first hospitalization ( TTFH ) and change in the EuroQoL EQ‐5D utility index score . Secondary outcomes included : rate of antibiotic/corticosteroid prescription ; hospitalization ; the COPD Assessment Tool , Patient Health Question naire‐9 , and Minnesota Living with Heart Failure question naire scores ; quality ‐adjusted life years ; and healthcare costs . Telemonitoring did not affect TTFH , EQ‐5D utility index score , antibiotic prescriptions , hospitalization rate , or question naire scores . In an exploratory analysis , telemedicine was associated with fewer repeat hospitalizations ( −54 % ; P = 0.017 ) . Conclusions : In older patients with COPD and comorbidities , remote monitoring of lung function by forced oscillation technique and cardiac parameters did not change TTFH and EQ‐5D . Clinical trial registered with www . clinical trials.gov ( NCT 01960907 ) Chronic obstructive pulmonary disease ( COPD ) is the leading cause of death worldwide , and poses a substantial economic and social burden . Telemonitoring has been proposed as a solution to this growing problem , but its impact on patient outcome is equivocal . This r and omized controlled trial aim ed to investigate effectiveness of telemonitoring in improving COPD patient outcome . In total , 106 subjects were r and omly assigned to the  telemonitoring  ( n = 53 ) or  usual care ( n = 53 ) group . During the two months following discharge , telemonitoring group patients had to report their symptoms daily using an electronic diary . The primary outcome measure was time to first re-admission for COPD exacerbation within six months of discharge . During the follow-up period , time to first re-admission for COPD exacerbation was significantly increased in the telemonitoring group than in the usual care group ( p = 0.026 ) . Telemonitoring was also associated with a reduced number of all-cause re-admissions ( 0.23 vs. 0.68/patient ; p = 0.002 ) and emergency room visits ( 0.36 vs. 0.91/patient ; p = 0.006 ) . In conclusion , telemonitoring intervention was associated with improved outcomes among COPD patients admitted for exacerbation in a country characterized by a small territory and high accessibility to medical services . The findings are encouraging and add further support to implementation of telemonitoring as part of COPD care We conducted a six-month r and omised controlled trial of home telemonitoring for patients with chronic obstructive pulmonary disease ( COPD ) . A total of 40 stable patients with moderate to severe COPD who had completed pulmonary rehabilitation took part . They were r and omised to receive st and ard care ( controls ) or st and ard care plus home telemonitoring ( intervention ) . During the monitoring period , patients in the telemonitoring group recorded their symptoms and physical observations twice daily . The data were transmitted automatically at night via the home telephone line . Nurses could access the data through a website and receive alerting email messages if certain conditions were detected . The patients completed the St George 's Respiratory Question naire , Hospital Anxiety and Depression and the EuroQoL EQ-5D quality of life scores before and after pulmonary rehabilitation , and then periodically during the trial . There were significant and clinical ly important improvements in the scores immediately following pulmonary rehabilitation , but thereafter there were no differences in quality of life scores between the groups at any time , or consistently within either group over time . The study showed that telemonitoring was safe but , despite being well used , it was not associated with changes in quality of life in patients who had stable COPD We studied the effect of telemonitoring in addition to usual care compared to usual care alone in patients with chronic obstructive pulmonary disease ( COPD ) . A total of 110 patients with moderate to severe COPD were recruited from a specialist respiratory service in Northern Irel and . Patients had at least two of : emergency department admissions , hospital admissions or emergency general practitioner ( GP ) contacts in the 12 months before the study . Exclusion criteria were patients who had any respiratory disorder other than COPD , or were cognitively unable to learn the process of monitoring . Patients were r and omised to receive six months of home telemonitoring with usual care , or six months of usual care . The primary outcome measure was disease-specific quality of life , as measured by the St George ’s Respiratory Question naire for COPD patients ( SGRQ-C ) . Of 100 patients completing the study , 48 patients were r and omised to telemonitoring and 52 patients were r and omised to the control group . The SGRQ-C scores improved significantly in the intervention group compared to usual care ( P = 0.001 ) . The HADS anxiety score was significantly higher in the telehealth group compared to the usual care group ( P = 0.01 ) . There were significantly more contacts with the Community Respiratory Team in the telemonitoring group compared to the control group ( P = 0.029 ) . There were no significant between group differences in EQ-5D scores , HADS depression scores , GP activity , emergency department visits , hospital admissions or exacerbations . The total cost to the health service of the intervention over the 6-month study period was £ 2039 , giving an estimated ICER of £ 203,900 . In selected patients with COPD , telemonitoring was effective in improving health-related quality of life and anxiety , but was not a cost-effective intervention The objective of this study was to determine the effects of a homebased telemonitoring device , The Health Buddy ( HB ) , on health consumption and health-related quality of life ( HRQoL ) in patients with moderate to severe chronic obstructive pulmonary disease ( COPD ) . The HB provides daily symptom-surveillance by a case manager and education to enhance disease knowledge and self-management . A nonr and omized controlled multicenter study was established comparing the effectiveness of telemonitoring as an add-on to care as usual with a follow-up of 6 months . Four hospitals took part in the experimental group and 2 hospitals formed an equivalent control group with 59 and 56 patients , respectively .  HRQoL was measured by the Clinical COPD Question naire . Healthcare consumption was assessed using medical records in the 6 months preceding study entry and during the study . Compared with the control group , the HB group showed a significant decrease in hospital admission rates ( HB -0.11 + /- 1.16 vs. control + 0.27 + /- 1.0 , p = 0.02 ) and in the total number of exacerbations ( HB -0.35 + /- 1.4 vs. control + 0.32 + /- 1.2 , p = 0.004 ) . There was a tendency toward decreased hospital days and outpatient visits . No significant changes in HRQoL were observed at follow-up between both study groups . Despite inherent limitations of the study , these findings suggest that adopting telemonitoring in everyday clinical practice is feasible and can substantially improve care and decrease healthcare utilization of patients with moderate to severe COPD Objective To assess the impact of home telemonitoring on health service use and quality of life in patients with severe chronic lung disease . Design R and omised crossover trial with 6 months of st and ard best practice clinical care ( control group ) and 6 months with the addition of telemonitoring . Participants 68 patients with chronic lung disease ( 38 with COPD ; 30 with chronic respiratory failure due to other causes ) , who had a hospital admission for an exacerbation within 6 months of r and omisation and either used long-term oxygen therapy or had an arterial oxygen saturation ( SpO2 ) of < 90 % on air during the previous admission . Individuals received telemonitoring ( second-generation system ) via broadb and link to a hospital-based care team . Outcome measures Primary outcome measure was time to first hospital admission for an acute exacerbation . Secondary outcome measures were hospital admissions , general practitioner ( GP ) consultations and home visits by nurses , quality of life measured by EuroQol-5D and hospital anxiety and depression ( HAD ) scale , and self-efficacy score ( Stanford ) . Results Median ( IQR ) number of days to first admission showed no difference between the two groups—77 ( 114 ) telemonitoring , 77.5 ( 61 ) control ( p=0.189 ) . Hospital admission rate at 6 months increased ( 0.63 telemonitoring vs 0.32 control p=0.026 ) . Home visits increased during telemonitoring ; GP consultations were unchanged . Self-efficacy fell , while HAD depression score improved marginally during telemonitoring . Conclusions Telemonitoring added to st and ard care did not alter time to next acute hospital admission , increased hospital admissions and home visits overall , and did not improve quality of life in chronic respiratory patients . Trial registration number NCT02180919 ( Clinical Trials.gov ) Background Telemonitoring technology offers one of the most promising alternatives for the provision of health care services at the patient 's home . The primary aim of this study is to evaluate the impact of a primary care-based telemonitoring intervention on the frequency of hospital admissions . Methods / design A primary care-based r and omised controlled trial will be carried out to assess the impact of a telemonitoring intervention aim ed at home care patients with heart failure ( HF ) and /or chronic lung disease ( CLD ) . The results will be compared with those obtained with st and ard health care practice . The duration of the study will be of one year . Sixty patients will be recruited for the study . In-home patients , diagnosed with HF and /or CLD , aged 14 or above and with two or more hospital admissions in the previous year will be eligible . For the intervention group , telemonitoring will consist of daily patient self- measurements of respiratory-rate , heart-rate , blood pressure , oxygen saturation , weight and body temperature . Additionally , the patients will complete a qualitative symptom question naire daily using the telemonitoring system . Routine telephone contacts will be conducted every fortnight and additional telephone contacts will be carried out if the data received at the primary care centre are out of the established limits . The control group will receive usual care . The primary outcome measure is the number of hospital admissions due to any cause that occurred in a period of 12 months post-r and omisation . The secondary outcome measures are : duration of hospital stay , hospital admissions due to HF or CLD , mortality rate , use of health care re sources , quality of life , cost-effectiveness , compliance and patient and health care professional satisfaction with the new technology . Discussion The results of this study will shed some light on the effects of telemonitoring for the follow-up and management of chronic patients from a primary care setting . The study may contribute to enhance the underst and ing of alternative modes of health care provision for medically unstable elderly patients , who bear a high degree of physical and functional deterioration . Trial Registration IS RCT N : IS RCT Objective To test the effectiveness of telemonitoring integrated into existing clinical services such that intervention and control groups have access to the same clinical care . Design Research er blind , multicentre , r and omised controlled trial . Setting UK primary care ( Lothian , Scotl and ) . Participants Adults with at least one admission for chronic obstructive pulmonary disease ( COPD ) in the year before r and omisation . We excluded people who had other significant lung disease , who were unable to provide informed consent or complete the study , or who had other significant social or clinical problems . Interventions Participants were recruited between 21 May 2009 and 28 March 2011 , and central ly r and omised to receive telemonitoring or conventional self monitoring . Using a touch screen , telemonitoring participants recorded a daily question naire about symptoms and treatment use , and monitored oxygen saturation using linked instruments . Algorithms , based on the symptom score , generated alerts if readings were omitted or breached thresholds . Both groups received similar care from existing clinical services . Main outcome measures The primary outcome was time to hospital admission due to COPD exacerbation up to one year after r and omisation . Other outcomes included number and duration of admissions , and vali date d question naire assessment s of health related quality of life ( using St George ’s respiratory question naire ( SGRQ ) ) , anxiety or depression ( or both ) , self efficacy , knowledge , and adherence to treatment . Analysis was intention to treat . Results Of 256 patients completing the study , 128 patients were r and omised to telemonitoring and 128 to usual care ;  baseline characteristics of each group were similar . The number of days to admission did not differ significantly between groups ( adjusted hazard ratio 0.98 , 95 % confidence interval 0.66 to 1.44 ) . Over one year , the mean number of COPD admissions was similar in both groups ( telemonitoring 1.2 admissions per person ( st and ard deviation 1.9 ) v control 1.1 ( 1.6 ) ; P=0.59 ) . Mean duration of COPD admissions over one year was also similar between groups ( 9.5 days per person ( st and ard deviation 19.1 ) v 8.8 days ( 15.9 ) ; P=0.88 ) . The intervention had no significant effect on SGRQ scores between groups ( 68.2 ( st and ard deviation 16.3 ) v 67.3 ( 17.3 ) ; adjusted mean difference 1.39 ( 95 % confidence interval −1.57 to 4.35 ) ) , or on other question naire outcomes . Conclusions In participants with a history of admission for exacerbations of COPD , telemonitoring was not effective in postponing admissions and did not improve quality of life . The positive effect of telemonitoring seen in previous trials could be due to enhancement of the underpinning clinical service rather than the telemonitoring communication . Trial registration IS RCT N96634935 . Funding : The trial was funded by an NHS applied research programme grant from the Chief Scientist Office of the Scottish government ( ARPG/07/03 ) . The funder had no role in study design and the collection , analysis , and interpretation of data and the writing of the article and the decision to su bmi t it for publication . NHS Lothian supported the telemonitoring service and the clinical services Background Chronic obstructive pulmonary disease ( COPD ) is a highly prevalent condition associated with a high health care re source consumption and health care expenditures , driven mainly by exacerbations-related hospitalizations . Telemedicine has been proposed as a mean for timely detection of exacerbation , but the available evidence is inadequate to provide conclusive information on its efficacy . The aim of this study is to evaluate the efficacy of a telemonitoring system in reducing COPD -related hospitalizations in an elderly population with COPD . Methods This is a parallel arms , r and omized trial including patients aged 65 or older with COPD in GOLD stages II and III enrolled in a Pulmonary Medicine outpatient facility . Patients were r and omly assigned to receive a non-invasive system able to telemonitor vital signs ( oxygen saturation , heart rate , near-body temperature , overall physical activity ) or st and ard care , and were followed up for 9 months . The outcome measures were the number of exacerbations and exacerbation-related hospitalization . Results Fifty patients were included in the telemonitoring group and 49 in the control group . The incidence rate of respiratory events was 28/100 person/years in the telemonitoring group vs. 42/100 person/years in the control group ( incidence rate ratio : 0.67 , 95 % CI : 0.32 – 1.36 ) . The corresponding figures for hospital admissions where 13/100 person/years and 20/100 person/years , respectively ( IRR : 0.66 , 95 % CI : 0.21 – 1.86 ) . Conclusions In our study , COPD patients followed up with the aid of a multiparametric remote monitoring system experienced a lower rate of exacerbations and COPD -related hospitalizations compared to patients followed up using the st and ard model of care . These results need to be replicated in larger studies before they can be applied to the general COPD population . Trial registration number : NCT01481506 ( clinical trials.gov ) . Funding : co-financed by Lazio Region and Intersistemi RATIONALE , AIMS AND OBJECTIVES The aim of the study was to evaluate the effects on , and the relationship between , asthma symptoms , asthma-specific quality of life and medical consumption of a nurse-led telemonitoring intervention compared with regular care in asthma in the Netherl and s. METHODS One hundred and nine asthmatic out patients ( 56 children ; 53 adults ) were r and omly assigned to the treatment arms ( 12-month follow-up ) . The control group received regular outpatient care , while the intervention group used an asthma monitor with modem at home with an asthma nurse as the main caregiver .  Clinical asthma symptoms and medical consumption were measured by using diaries . Asthma-specific quality of life was measured by the ( Paediatric ) Asthma Quality of Life Question naire . RESULTS The study population generally represented mild to moderate asthmatics . The results show improvement in follow-up , but no statistically significant difference between the groups was observed . Moderate to high correlations were found within the outcome parameters , but the most remarkable was the low and statistically significant correlation between asthma-specific quality of life ( daily functioning ) and the self-reported beta-2 agonists . CONCLUSION Overall , the telemonitoring programme evaluated in this study did not significantly decrease asthma symptoms or medical consumption , or improve asthma-specific quality of life . The results showed that a telemonitoring programme on its own is not a guarantee of success . The patients ' perception of asthma-specific quality of life ( daily functioning ) should be a key element in asthma telemonitoring programmes OBJECTIVE To assess the impact of a home telemonitoring technology on patients with chronic obstructive pulmonary disease in terms of care satisfaction , patient empowerment , improved quality of life , and utilization of hospital and home care . DESIGN A quasi-experimental retrospective and prospect i ve design was developed with a matched control group to compare the effects of telemonitoring  ( the experimental group , n = 23 ) with the traditional homecare offering  ( the control group , n = 23 ) . MEASUREMENTS Satisfaction , patient empowerment , and quality of life were measured using vali date d Likert scales , whereas the data on care utilization were collected from the participating patients ' medical record . RESULTS Mixed results were observed . The clinical effects of home telemonitoring were very positive in terms of patients ' satisfaction and empowerment . The perceptions of care providers as well as those of patients were congruent in this respect . Also , the study suggests that telemonitoring may have a positive effect on quality of life for patients with chronic obstructive pulmonary diseases . In contrast , the results were disappointing in terms of re source savings for the use of both homecare and hospital care . CONCLUSION Capturing the full potential of these new technologies will require a much more fundamental reorganization of work than just a simple deployment of the technology Both congestive heart failure and chronic obstructive pulmonary disease are more common among Māori than non-Māori people , and the cultural acceptability of home-based remote monitoring technology has not been tested . We conducted a 12-month pilot trial of home telemonitoring .  Patients were r and omly assigned to the control and intervention groups . Patients in the control group showed no clear differences in quality of life at the end of the trial . The telehealth group showed a consistent trend towards improved quality of life on several instruments , including the SF-36 , the St George Respiratory Question naire and the K10 question naire ; the improvement in the latter was significant . Hospitalizations were reduced in both the control ( −19 % ) and telehealth group ( −25 % ) . Patient interviews indicated that the technology was acceptable to most patients and their families , including the Māori . The results from the pilot trial suggest that wider implementation with a cost benefit evaluation could be worthwhile OBJECTIVE To explore patient and professional views on self-management in the context of telemonitoring in chronic obstructive pulmonary disease ( COPD ) . METHODS Semi-structured interviews with patients with COPD and healthcare professionals participating in a r and omized controlled trial of telemonitoring in Lothian , Scotl and , explored experiences of using telemonitoring , and dynamics in patient-practitioner relationships . Transcribed data were analyzed using the Framework approach . RESULTS 38 patients ( mean age 67.5 years ) and 32 professionals provided 70 interviews . Patients considered that telemonitoring empowered self-management by enhancing their underst and ing of COPD and providing additional justification for their decisions to adjust treatment or seek professional advice . Professionals discussed telemonitoring as promoting compliance with medical advice and encouraged patients to exercise personal responsibility within clinical parameters , but expressed concerns about promoting the sick role and creating dependence on telemonitoring . CONCLUSION Telemonitoring assisted many patients to embrace greater responsibility for their health but the model of service provision remained clinician-centered . A medical model of ' compliant self-management ' may paradoxically have promoted dependence on professionals . PRACTICE IMPLICATION S Patients and professionals shared responsibility for meeting the central objective of prompt management of exacerbations of COPD . Care is needed , however , to minimize the risk in some patients , of telemonitoring increasing dependence on practitioner support Background There is growing evidence that home telemonitoring can be advantageous in societies with increasing prevalence of chronic diseases . The main objective of this study is to evaluate the effect of a primary care-based telemonitoring intervention on the number and length of hospital admissions . Methods A r and omised controlled trial was carried out across 20 health centres in Bilbao ( Basque Country , Spain ) to assess the impact of home telemonitoring on in-home chronic patients compared with st and ard care . The study lasted for one year . Fifty-eight in-home patients , diagnosed with heart failure ( HF ) and /or chronic lung disease ( CLD ) , aged 14 or above and with two or more hospital admissions in the previous year were recruited . The intervention consisted of daily patient self- measurements of respiratory-rate , heart-rate , blood pressure , oxygen saturation , weight , body temperature and the completion of a health status question naire using PDAs . Alerts were generated when pre-established thresholds were crossed . The control group ( CG ) received usual care . The primary outcome measure was the number of hospital admissions that occurred at 12 months post-r and omisation . The impact of telemonitoring on the length of hospital stay , use of other healthcare re sources and mortality was also explored . Results The intervention group ( IG ) included 28 patients and the CG 30 . Patient baseline characteristics were similar in both groups . Of the 21 intervention patients followed-up for a year , 12 had some admissions ( 57.1 % ) , compared to 19 of 22 controls ( 86.4 % ) , being the difference statistically significant ( p = 0.033 , RR 0.66 ; 95%CI 0.44 to 0.99 ) . The mean hospital stay was overall 9 days ( SD 4.3 ) in the IG versus 10.7 ( SD 11.2 ) among controls , and for cause-specific admissions 9 ( SD 4.5 ) vs. 11.2 ( SD 11.8 ) days , both without statistical significance ( p = 0.891 and 0.927 , respectively ) . Four patients need to be telemonitored for a year to prevent one admission ( NNT ) . There were more telephone contacts in the IG than in the CG ( 22.6 -SD 16.1- vs. 8.6 -SD 7.2- , p = 0.001 ) , but fewer home nursing visits ( 15.3 -SD 11.6- vs. 25.4 -SD 26.3- , respectively ) , though the difference was not statistically significant ( p = 0.3603 ) . Conclusions This study shows that telemonitoring of in-home patients with HF and /or CLD notably increases the percentage of patients with no hospital admissions and indicates a trend to reduce total and cause-specific hospitalisations and hospital stay .  Home telemonitoring can constitute a beneficial alternative mode of healthcare provision for medically unstable elderly patients .Trial registration Current Controlled Trials IS RCT BACKGROUND Continuity of care is widely regarded as an important marker of quality in the management of patients with long-term conditions . New services that integrate telemonitoring into care pathways have potential to change aspects of continuity in both positive and negative ways . AIMS A telemonitoring service for patients with chronic obstructive pulmonary disease ( COPD ) was introduced in Lothian , Scotl and , in 2009 . A qualitative study , nested within the TELESCOT COPD r and omised control trial , was undertaken to explore the views of patients and professionals on  telemonitoring . The perceived impact of telemonitoring on continuity of care was investigated as part of the research . METHODS Semi-structured interviews were undertaken with 38 patients ( 47 % male , mean age 67.5 years ) . A maximum variation sample in relation to age , sex , socio-economic background , disease severity , and compliance with telemonitoring was recruited . Thirty-two stakeholders ( healthcare professionals and managers ) were interviewed . Transcribed coded data were analysed thematically using the framework approach . Interpretation was supported by multidisciplinary discussion . RESULTS Patients and healthcare professionals considered that relationship-based continuity of care was important in the delivery of telemonitoring services . Managers placed emphasis on improved continuity of clinical management as a means of reducing healthcare costs . However , professionals described many operational challenges arising from the ' bolting-on ' of telemonitoring provision to existing usual care provision which , they considered , result ed in the proliferation of additional managerial discontinuities . CONCLUSIONS Managers and healthcare professionals face major challenges in meeting dem and s for both relationship continuity and continuity of clinical management in the development of telemonitoring services BACKGROUND The increasing prevalence of chronic diseases requires changes in health care delivery . In COPD , telemedicine appears to be a useful tool . Our objective was to evaluate the efficacy ( in improving health care-re source use and clinical outcomes ) of a telemonitoring-based program ( telEPOC ) in COPD patients with frequent hospitalizations . MATERIAL S AND METHODS We conducted a nonr and omized observational study in an intervention cohort of 119 patients ( Galdakao-Usansolo Hospital ) and a control cohort of 78 patients ( Cruces Hospital ) , followed up for 2 years ( Clinical Trials.gov identifier : NCT02528370 ) . The inclusion criteria were two or more hospital admissions in the previous year or three or more admissions in the previous 2 years . The intervention group received telemonitoring plus education and controls usual care . RESULTS Most participants were men ( 13 % women ) , and the sample had a mean age of 70 years , forced expiratory volume in 1 second of 45 % , Charlson comorbidity index score of 3.5 , and BODE ( body mass index , airflow obstruction , dyspnea , and exercise capacity ) index score of 4.1 . In multivariate analysis , the intervention was independently related to lower rates of hospital admission ( odds ratio [ OR ] 0.38 , 95 % confidence interval [ CI ] 0.27 - 0.54 ; P<0.0001 ) , emergency department attendance ( OR 0.56 , 95 % CI 0.35 - 0.92 ; P<0.02 ) , and 30-day readmission ( OR 0.46 , 95 % CI 0.29 - 0.74 ; P<0.001 ) , as well as cumulative length of stay ( OR 0.58 , 95 % CI 0.46 - 0.73 ; P<0.0001 ) . The intervention was independently related to changes in several clinical variables during the 2-year follow-up . CONCLUSION An intervention including telemonitoring and education was able to reduce the health care-re source use and stabilize the clinical condition of frequently admitted COPD patients ABSTRACT Aim . To see if home telemonitors reduce healthcare use in those with optimized chronic obstructive pulmonary disease ( COPD ) . Methods . We r and omized 40 stable patients with moderate to severe COPD , who had completed at least 12 sessions of outpatient pulmonary rehabilitation ( PR ) , to receive st and ard care ( Controls ) for 52 weeks or st and ard care plus Docobo HealthHUB monitors at home for 26 weeks followed by 26 weeks st and ard care ( Tm Group ) . During the monitoring period , the Tm Group completed  symptoms and physical observations  twice daily which were stored and then uploaded at 2 am through a freephone l and line . Nurses could access the data through a secure web site and received alerting e-mails if certain combinations of data occurred . Results . There were fewer primary care contacts for chest problems ( p < 0.03 ) in the Tm group , but no differences between the groups in emergency room visits , hospital admissions , days in hospital or contacts to the specialist COPD community nurse team , during the monitoring period . After the monitors were removed , there were no differences between the groups for any of the health care contacts ( p > 0.20 throughout ) . Conclusion . In stable , optimized COPD patients who have already completed PR , telemonitoring in addition to best care , reduces primary care chest contacts but not hospital or specialist team utilization
Only then will telemonitoring achieve the aim of preventing hospital admissions , contributing to the reduction of health re source utilization and improving the quality of life of patients
Major reported factors associated with the limited effectiveness of home telemonitoring interventions in chronic respiratory conditions include the lack of useful early predictors , poor patient compliance and the poor performance of conventional algorithms for detecting deteriorations .
This article provides a systematic review of existing algorithms and the factors associated with their performance in detecting exacerbations and supporting clinical decisions in patients with chronic obstructive pulmonary disease ( COPD ) or asthma .
