    Input: Background Telehealth ( TH ) and telecare ( TC ) interventions are increasingly valued for supporting self-care in ageing population s ; however , evaluation studies often report high rates of non-participation that are not well understood . This paper reports from a qualitative study nested within a large r and omised controlled trial in the UK : the Whole System Demonstrator ( WSD ) project . It explores barriers to participation and adoption of TH and TC from the perspective of people who declined to participate or withdrew from the trial . Methods Qualitative semi-structured interviews were conducted with 22 people who declined to participate in the trial following explanations of the intervention ( n = 19 ) , or who withdrew from the intervention arm ( n = 3 ) . Participants were recruited from the four trial groups ( with diabetes , chronic obstructive pulmonary disease , heart failure , or social care needs ) ; and all came from the three trial areas ( Cornwall , Kent , east London ) . Observations of home visits where the trial and interventions were first explained were also conducted by shadowing 8 members of health and social care staff visiting 23 people at home . Field notes were made of observational visits and explored alongside interview transcripts to elicit key themes . Results Barriers to adoption of TH and TC  associated with non-participation and withdrawal from the trial were identified within the following themes : requirements for technical competence and operation of equipment ; threats to identity , independence and self-care ; expectations and experiences of disruption to services . Respondents held concerns that special skills were needed to operate equipment but these were often based on misunderst and ings . Respondents ’ views were often explained in terms of potential threats to identity associated with positive ageing and self-reliance , and views that interventions could undermine self-care and coping . Finally , participants were reluctant to risk potentially disruptive changes to existing services that were often highly valued . Conclusions These findings regarding perceptions of potential disruption of interventions to identity and services go beyond more common expectations that concerns about privacy and dislike of technology deter uptake . These insights have implication s for health and social care staff indicating that more detailed information and time for discussion could be valuable especially on introduction . It seems especially important for potential recipients to have the opportunity to discuss their expectations and such views might usefully feed back into design and implementation 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 Early treatment of COPD exacerbations has shown to be important . Despite a non-negligible negative impact on health related quality of life , a large proportion of these episodes is not reported ( no change in treatment ) . Little is known whether ( low burden ) strategies are able to capture these unreported exacerbations . Methods The Clinical COPD Question naire ( CCQ ) is a short question naire with great evaluative properties in measuring health status . The current explorative study evaluates the discriminative properties of weekly CCQ assessment in detecting exacerbations . Results In a multicentre prospect i ve cohort study , 121 patients , age 67.4 ± 10.5 years , FEV1 47.7 ± 18.5 % pred were followed for 6 weeks by daily diary card recording and weekly CCQ assessment . Weeks were retrospectively labeled as stable or exacerbation ( onset ) weeks using the Anthonisen symptom diary-card algorithm . Change in CCQ total scores are significantly higher in exacerbation-onset weeks , 0.35 ± 0.69 compared to -0.04 ± 0.37 in stable weeks ( p < 0.001 ) . Performance of the Δ CCQ total score discriminating between stable and exacerbation onset weeks was sufficient ( area under the ROC curve 0.75 ) . At a cut off point of 0.2 , sensitivity was 62.5 ( 50.3 - 73.4 ) , specificity 82.0 ( 79.3 - 84.4 ) , and a positive and negative predictive value of 43.5 ( 35.0 - 51.0 ) and 90.8 ( 87.8 - 93.5 ) , respectively . Using this cut off point , 22 ( out of 38 ) unreported exacerbations were detected while 39 stable patients would have been false positively ' contacted ' . Conclusions Weekly CCQ assessment is a promising , low burden method to detect unreported exacerbations . Further research is needed to vali date discriminative performance and practical implication s of the CCQ in detecting exacerbations in daily care National Asthma Education and Prevention Program ( NAEPP ) suggests using asthma action plans for patient self-care . Recent studies reported that many asthma patients had difficulties in following action plans on a daily basis and had low compliance to medication regimens . The goal of our study was to design and evaluate the Home Asthma Telemonitoring ( HAT ) system aim ed to help asthma patients to follow their self-care plans according to the NAEPP recommendations . Our study result ed in the development of the system which provided patients with continuous individualized help in the daily routine of asthma self-care and notified heath care providers if certain clinical conditions occurred . This allowed early recognition of potentially dangerous situations and timely intervention . The evaluation of the HAT system underwent several stages . First we showed , that the HAT system provides reliable reciprocal exchange of all relevant information between a physician and asthma patient in home setting s. Further evaluation demonstrated that lung function test results collected during home asthma telemonitoring are comparable to those collected under the supervision of trained professionals , and Internet-based home asthma telemonitoring can be successfully implemented in a group of patients without previous computer experience . Preliminary results of an on-going HAT evaluation showed higher patient compliance to asthma action plans in comparison to the compliance reported for patients in st and ard care . The clinical impact of HAT on asthma outcomes is being currently evaluated in a r and omized clinical trial funded by NIH . HAT has a potential for improving clinical outcomes and quality of life in the studied patient population and may be a model for monitoring and self-management of patients with other chronic health conditions Objective To assess the effect of second generation , home based telehealth on health related quality of life , anxiety , and depressive symptoms over 12 months in patients with long term conditions . Design A study of patient reported outcomes ( the Whole Systems Demonstrator telehealth question naire study ; baseline n=1573 ) was nested in a pragmatic , cluster r and omised trial of telehealth ( the Whole Systems Demonstrator telehealth trial , n=3230 ) . General practice was the unit of r and omisation , and telehealth was compared with usual care . Data were collected at baseline , four months ( short term ) , and 12 months ( long term ) . Primary intention to treat analyses tested treatment effectiveness ; multilevel models controlled for clustering by general practice and a range of covariates . Analyses were conducted for 759 participants who completed question naire measures at all three time points ( complete case cohort ) and 1201 who completed the baseline assessment plus at least one other assessment ( available case cohort ) . Secondary per protocol analyses tested treatment efficacy and included 633 and 1108 participants in the complete case and available case cohorts , respectively . Setting Provision of primary and secondary care via general practice s , specialist nurses , and hospital clinics in three diverse regions of Engl and ( Cornwall , Kent , and Newham ) , with established integrated health and social care systems . Participants Patients with chronic obstructive pulmonary disease ( COPD ) , diabetes , or heart failure recruited between May 2008 and December 2009 . Main outcome measures Generic , health related quality of life ( assessed by physical and mental health component scores of the SF-12 , and the EQ-5D ) , anxiety ( assessed by the six item Brief State-Trait Anxiety Inventory ) , and depressive symptoms ( assessed by the 10 item Centre for Epidemiological Studies Depression Scale ) . Results In the intention to treat analyses , differences between treatment groups were small and non-significant for all outcomes in the complete case ( 0.480≤P≤0.904 ) or available case ( 0.181≤P≤0.905 ) cohorts . The magnitude of differences between trial arms did not reach the trial defined , minimal clinical ly important difference ( 0.3 st and ardised mean difference ) for any outcome in either cohort at four or 12 months . Per protocol analyses replicated the primary analyses ; the main effect of trial arm ( telehealth v usual care ) was non-significant for any outcome ( complete case cohort 0.273≤P≤0.761 ; available case cohort 0.145≤P≤0.696 ) . Conclusions Second generation , home based telehealth as implemented in the Whole Systems Demonstrator Evaluation was not effective or efficacious compared with usual care only . Telehealth did not improve quality of life or psychological outcomes for patients with chronic obstructive pulmonary disease , diabetes , or heart failure over 12 months . The findings suggest that concerns about potentially deleterious effect of telehealth are unfounded for most patients . Trial Registration IS RCT N43002091 Objectives To assess the effect of telecare on health related quality of life , self-care , hospital use , costs and the experiences of patients , informal carers and health care professionals . Methods Patients were r and omly assigned either to usual care or to additionally entering their data into a commercially-available electronic device that uploaded data once a day to a nurse-led monitoring station . Patients had congestive heart failure ( Site A ) , chronic obstructive pulmonary disease ( Site B ) , or any long-term condition , mostly diabetes ( Site C ) . Site C contributed only intervention patients – they considered a usual care option to be unethical . The study took place in New Zeal and between September 2010 and February 2012 , and lasted 3 to 6 months for each patient . The primary outcome was health-related quality of life ( SF36 ) . Data on experiences were collected by individual and group interviews and by question naire . Results There were 171 patients ( 98 intervention , 73 control ) . Quality of life , self-efficacy and disease-specific measures did not change significantly , while anxiety and depression both decreased significantly with the intervention . Hospital admissions , days in hospital , emergency department visits , outpatient visits and costs did not differ significantly between the groups . Patients at all sites were universally positive . Many felt safer and more cared-for , and said that they and their family had learned more about managing their condition . Staff could all see potential benefits of telecare , and , after some initial technical problems , many staff felt that telecare enabled them to effectively monitor more patients . Conclusions Strongly positive patient and staff
