Helping COPD patients change health behavior in order to improve their quality of life

Remote monitoring of patients with COPD disease using a tablet system: a randomised crossover study of quality-of-life measurements

Background

Remote patient monitoring (RPM) has been evaluated in COPD, but with varying results. We aimed to evaluate whether a tablet system that monitors disease-related parameters in patients with COPD could influence physical and mental health-related quality of life, compared with usual care (UC).

Methods

70 patients with Global Initiative for Chronic Obstructive Lung Disease (GOLD) group D COPD (61% women, aged 71±8 years, forced expiratory volume in 1 s % predicted 41±13%, COPD Assessment Test (CAT) 19±7 points) were recruited at the COPD centre in Gothenburg, Sweden, and randomised to a tablet-based RPM system or UC for a 26-week period, after which they crossed over to the alternative management for another 26 weeks. The Short Form-12 (SF-12) (primary outcome), CAT, modified Medical Research Council (mMRC) Dyspnoea Scale, EuroQol-5 Dimensions (EQ-5D) and Hospital Anxiety and Depression Scale (HADS) were evaluated at four visits. Exacerbations were continuously reported, as was adherence to RPM.

Results

59 patients completed the study: 28 patients randomised to start with UC and 31 randomised to start with RPM. The changes in the SF-12 Physical Component Summary (PCS) (UC: -1.17±6.90 versus RPM: -1.06±8.15) and Mental Component Summary (MCS) (UC: 0.63±11.14 versus RPM: -0.63±8.15), as well as in CAT, the mMRC scale, the EQ-5D, HADS anxiety, HADS depression and number of exacerbations, were similar in both intervention periods. Neither the 26-week UC period nor the intervention significantly affected the measured outcomes. There was a 95% adherence rate during RPM.

Conclusions

A 26-week tablet-based RPM system that monitors CAT, oxygen saturation, blood pressure, pulse, weight and physical activity, connected to a case manager, is feasible and safe, but did not influence health-related quality of life in patients with COPD GOLD D.

Efficacy and safety of ensifentrine, a novel phosphodiesterase 3 and 4 inhibitor, in chronic obstructive pulmonary disease: A systematic review and meta-analysis

BACKGROUND

We evaluated the efficacy and safety of Ensifentrine in COPD via a systematic review and meta-analysis of randomized controlled trials (RCTs).

METHODS

We performed a detailed literature search on Medline (via PubMed), Scopus, Google Scholar, and Cochrane on the basis of pre-specified eligibility criteria. We used Review Manager to calculate pooled mean differences (MD) and 95% Confidence Interval (CI) using a random effects model. The Cochrane's Risk of Bias 2 (RoB-2) tool was used to assess the risk of bias in the included RCTs.

RESULTS

A total of 4 studies, consisting of 2020 patients, were included in the meta-analysis. The mean age ranged from 62.5 years to 65.5 years in the included studies. All the included studies were at low risk of bias. Ensifentrine 3 mg dose significantly improved the mean peak Forced Expiratory Volume-1 (FEV-1), morning trough FEV-1, TDI score, ERS score, and SGRQ-C score as compared to the placebo, yielding a pooled MD of 149.76 (95% CI, 127.9 to 171.6), 43.93 (95% CI, 23.82 to 64.05), 0.92 (95% CI, 0.64 to 1.21, -1.20 (95% CI, -1.99 to -0.40), and -1.92 (95% CI, -3.24 to -0.59), respectively.

CONCLUSION

Ensifentrine is associated with improvements in outcomes related to COPD symptoms such as peak FEV-1, morning trough FEV-1 and TDI in the patients suffering from this chronic disease. It is also associated with improved quality of life as seen by E-RS score and SGRQ-C score.

Facilitators and barriers to self-management in Iranian men with chronic obstructive pulmonary disease: a qualitative study

INTRODUCTION

Self-management, as the most common method of chronic obstructive pulmonary disease (COPD) management, is not an isolated behaviour, but a set of physical, social, cultural, psychological and existential factors affecting it.

AIM

This study aimed to explore the facilitators and barriers to self-management in men with COPD in the unique social, cultural, political and economic context of Iran.

METHODS

This paper reports part of the findings of a qualitative grounded theory study aimed at exploring the process of self-management in Iranian men with COPD, which was conducted in Iran from January 2019 to July 2023. Participants included men with COPD, their family members and pulmonologists. The selection of participants in this research began with the purposeful sampling method. Data was collected using semistructured interviews. Data collection continued until the data saturation was achieved. A total of 15 interviews were conducted with nine patients, three family members of patients and three pulmonologists. The data was analysed using the constant comparative analysis method.

RESULTS

The findings of this study showed that knowledge, education, experience, family involvement and financial support are the factors that facilitate self-management. Factors related to deficits include lack of education, lack of treatment support, family cooperation deficit, financial problems, medication obtaining problems and factors related to disease impacts include specific nature of the disease, residual effect, comorbidity and factors related to negative patients characteristics include false beliefs, poor self-efficacy, feeling shame and non-adherence are barriers to self-management in men with COPD.

CONCLUSION

Based on results of this study, healthcare providers and health planners can strengthen the factors that facilitate self-management and weaken or remove the barriers to self-management, so that these patients use self-management strategies with maximum capacity to control the disease.

Effectiveness of remote home monitoring for patients with Chronic Obstructive Pulmonary Disease (COPD): systematic review

Background

Although remote home monitoring (RHM) has the capacity to prevent exacerbations in patients with chronic obstructive pulmonary disease (COPD), evidence regarding its effectiveness remains unclear. The objective of this study was to determine the effectiveness of RHM in patients with COPD.

Methods

A systematic review of the scholarly literature published within the last 10 years was conducted using internationally recognized guidelines. Search strategies were applied to several electronic databases and clinical trial registries through March 2020 to identify studies comparing RHM to ‘no remote home monitoring’ (no RHM) or comparing RHM with provider’s feedback to RHM without feedback. To critically appraise the included randomized studies, the Cochrane Collaboration risk of bias tool (ROB) was used. The quality of included non-randomized interventional and comparative observational studies was evaluated using the ACROBAT-NRSI tool from the Cochrane Collaboration. The quality of evidence relating to key outcomes was assessed using Grading of Recommendations, Assessment, Development and Evaluations (GRADE) on the following: health-related quality of life (HRQoL), patient experience and number of exacerbations, number of emergency room (ER) visits, COPD-related hospital admissions, and adherence as the proportion of patients who completed the study. Three independent reviewers assessed methodologic quality and reviewed the studies.

Results

Seventeen randomized controlled trials (RCTs) and two comparative observational studies were included in the review. The primary finding of this systematic review is that a considerable amount of evidence relating to the efficacy/effectiveness of RHM exists, but its quality is low. Although RHM is safe, it does not appear to improve HRQoL (regardless of the type of RHM), lung function or self-efficacy, or to reduce depression, anxiety, or healthcare resource utilization. The inclusion of regular feedback from providers may reduce COPD-related hospital admissions. Though adherence RHM remains unclear, both patient and provider satisfaction were high with the intervention.

Conclusions

Although a considerable amount of evidence to the effectiveness of RHM exists, due to heterogeneity of care settings and the low-quality evidence, they should be interpreted with caution.

Nutrition as a modifiable factor in the onset and progression of pulmonary function impairment in COPD: a systematic review

CONTEXT

Chronic obstructive lung disease (COPD) is a progressive lung disease characterized by persistent airflow limitation. An increasing amount of evidence suggests an effect of dietary quality on the risk of COPD in the general population and pulmonary function decline in patients with COPD.

OBJECTIVE

The association of dietary intake and nutrient status with COPD risk and onset, as well as pulmonary function decline (change in forced expiratory volume in 1 second, forced vital capacity, or the ratio of the former to the latter) in patients with COPD was investigated in this systematic review.

DATA SOURCES

The PubMed database was searched by combining terms of pulmonary function or COPD with diet, nutrient status, or nutritional supplementation.

DATA EXTRACTION

Original studies and systematic reviews and meta-analyses were included. Articles obtained were independently screened for relevance on the bases of title and abstract by 2 researchers. Eventually, 89 articles were included in the analysis.

RESULTS

The unhealthy Western-style diet is associated with an increased risk of COPD and an accelerated decline of pulmonary function. Intake of fruit, vegetables, dietary fibers, vitamins C and E, polyphenols, and β-carotene were individually associated with lower COPD risk, whereas consumption of processed meat was associated with higher COPD risk. Data on the effect of dietary quality on pulmonary function decline in patients with COPD are limited and inconsistent. Strong evidence for beneficial effects on pulmonary function decline was found only for vitamin D supplementation.

CONCLUSION

Considering the increasing burden of COPD, more attention should be given to dietary quality as a modifiable factor in disease development and progression in patients with COPD.

The Effect of Nursing Care Applied to Patients with Chronic Obstructive Pulmonary Disease on Their Sexual Experiences and Quality of Life

This study was conducted for the aim of assessing the effect of nursing care applied to patients with chronic obstructive pulmonary disease on their sexual experiences and quality of life. The sample of the study was determined via power analysis, patients were assigned groups using a simple random sampling method. The data were collected between December 2019-June 2020. The researcher applied the nursing care to patients in the experimental group in their home three times. There was a statistically significant difference between posttest mean scores of the Short Form-36 Health-Related Quality of Life Questionnaire subscales and Arizona Sexual Experiences Scale of the patients in the experimental and control groups (p < 0.05). In this study, it was determined that there was an increase in the Health-Related Quality of Life Questionnaire mean score of patients with COPD after the nursing care; whereas, there was a slight decrease in the Arizona Sexual Experiences Scale mean score.

Development and Preliminary Evaluation of the Effects of an mHealth Web-Based Platform (HappyAir) on Adherence to a Maintenance Program After Pulmonary Rehabilitation in Patients With Chronic Obstructive Pulmonary Disease: Randomized Controlled Trial

Background

Pulmonary rehabilitation is one of the main interventions to reduce the use of health resources, and it promotes a reduction in chronic obstructive pulmonary disease (COPD) costs. mHealth systems in COPD aim to improve adherence to maintenance programs after pulmonary rehabilitation by promoting the change in attitude and behavior necessary for patient involvement in the management of the disease.

Objective

This study aimed to assess the effects of an integrated care plan based on an mHealth web-based platform (HappyAir) on adherence to a 1-year maintenance program applied after pulmonary rehabilitation in COPD patients.

Methods

COPD patients from three hospitals were randomized to a control group or an intervention group (HappyAir group). Patients from both groups received an 8-week program of pulmonary rehabilitation and educational sessions about their illness. After completion of the process, only the HappyAir group completed an integrated care plan for 10 months, supervised by an mHealth system and therapeutic educator. The control group only underwent the scheduled check-ups. Adherence to the program was rated using a respiratory physiotherapy adherence self-report (CAP FISIO) questionnaire. Other variables analyzed were adherence to physical activity (Morisky-Green Test), quality of life (Chronic Obstructive Pulmonary Disease Assessment Test, St. George’s Respiratory Questionnaire, and EuroQOL-5D), exercise capacity (6-Minute Walk Test), and lung function.

Results

In total, 44 patients were recruited and randomized in the control group (n=24) and HappyAir group (n=20). Eight patients dropped out for various reasons. The CAP FISIO questionnaire results showed an improvement in adherence during follow-up period for the HappyAir group, which was statistically different compared with the control group at 12 months (56.1 [SD 4.0] vs 44.0 [SD 13.6]; P=.004) after pulmonary rehabilitation.

Conclusions

mHealth systems designed for COPD patients improve adherence to maintenance programs as long as they are accompanied by disease awareness and patient involvement in management.

Brief cognitive behavioral therapy reduces suicidal ideation in veterans with chronic illnesses

OBJECTIVE

We evaluated the effect of brief cognitive behavioral therapy (bCBT) on suicidal ideation among medically ill veterans receiving mental health treatment in primary care.

METHODS

Secondary analysis was conducted on data collected during a multisite, patient-randomized trial investigating the impact of bCBT (n = 180) on depression and anxiety symptoms, relative to enhanced usual care (EUC; n = 122), in patients with congestive heart failure and/or chronic obstructive pulmonary disease. BCBT was delivered by primary care mental health providers over 4 months, with follow-up posttreatment assessments of suicidal ideation, measured by the Patient Health Questionnaire-9 (item 9) at 4, 8, and 12 months. Suicidal ideation was the primary outcome examined in the current analysis. Generalized estimating equations modeling suicidal ideation were used to compare the study arms.

RESULTS

Participants receiving bCBT were less likely to have high suicidal ideation than participants receiving EUC posttreatment and at 8-month follow-up after accounting for baseline suicidal ideation. Within-group comparisons suggest participants receiving bCBT were less likely to have high suicidal ideation at 4, 8, and 12 months when compared with baseline. High suicidal ideation for EUC participants did not differ at 4, or 8 months, but they were less likely to have high suicidal ideation at 12 months.

CONCLUSION

bCBT in primary care reduces suicidal ideation and may help prevent future suicidal ideation.

How does it work? Factors involved in telemedicine home-interventions effectiveness: A review of reviews

Introduction

Definitive evidence of the effectiveness and cost-effectiveness of telemedicine home-interventions for the management of chronic diseases is still lacking. This study examines whether and how published reviews consider and discuss the influence on outcomes of different factors, including: setting, target, and intensity of intervention; patient engagement; the perspective of patients, caregivers and health professionals; the organizational model; patient education and support. Included reviews were also assessed in terms of economic and ethical issues.

Methods

Two search algorithms were developed to scan PubMed for reviews published between 2000 and 2015, about ICT-based interventions for the management of hypertension, diabetes, heart failure, asthma, chronic obstructive pulmonary disease, or for the care of elderly patients. Based on our inclusion criteria, 25 reviews were selected for analysis.

Results

None of the included reviews covered all the above-mentioned factors. They mostly considered target (44%) and intervention intensity (24%). Setting, ethical issues, patient engagement, and caregiver perspective were the most neglected factors (considered in 0–4% of the reviews). Only 4 reviews (16%) considered at least 4 of the 11 factors, the maximum number of factors considered in a review is 5.

Conclusions

Factors that may be involved in ICT-based interventions, affecting their effectiveness or cost-effectiveness, are not enough studied in the literature. This research suggests to consider mostly the role of each one, comparing not only disease-related outcomes, but also patients and healthcare organizations outcomes, and patient engagement, in order to understand how interventions work.

COPD patient education and support - Achieving patient-centredness

BACKGROUND

The art of medicine is undergoing a dramatic shift in focus, evolving to focus on patient involvement as partners in care, transforming the traditional, prescriptive, reactive practice of healthcare into a proactive discipline. The personal and societal burden of chronic diseases is burgeoning and unsustainable in current systems, novel approaches are required to address this.

DISCUSSION

Although considerable progress has been made in the development of diagnostics, therapeutics and care guidelines for patients with chronic obstructive pulmonary disease (COPD), questions remain surrounding the implementation of best practice education and support. Current educational programmes, personal limitations and preferences and patient-clinician communication in modification of coping styles and behaviour are discussed. A novel holistic model, the Kaleidoscope Model of Care is proposed to address the barriers to optimal self-care behaviours.

CONCLUSION AND PRACTICE IMPLICATIONS

Holistic approaches are essential for optimal self-management and improved outcomes. Guidance on personalised goals for patients to help meeting their therapy priorities is needed to aid healthcare professionals (HCPs) and funders to minimise healthcare burden and costs. The novel KALMOD approach may optimise patient empowerment, exploring whole-life factors that impact COPD care and improve interactions between patients and HCPs for optimised outcomes.

Resilience Factors Important in Health-Related Quality of Life of Subjects With COPD

BACKGROUND

Common among patients with COPD is declining health-related quality of life (HRQOL). Although results of research identified some factors associated with HRQOL, resilience factors are yet to be fully investigated.

METHODS

This study examined resilience and demographic factors associated with HRQOL. Participants >40 y old were recruited from community health programs and hospitals in South East Queensland. Self-administered questionnaires were used to query subjects' HRQOL and levels of resilience. A decision tree examined the factors important to HRQOL in 159 subjects with COPD.

RESULTS

Factors of importance in the HRQOL of subjects with COPD were found in 3 domains of the St George Respiratory Questionnaire. Of importance on the breathlessness domain was marital status, defensive coping, coping, number of comorbidities, relationships, decision-making, self-esteem, self-efficacy, and professional support of health and well-being. Of the symptoms domain, self-efficacy, recruitment location, anxiety/depression, decision-making, self-esteem, coping, relationships, professional support of health and well-being, and risks were important. The cough domain found recruitment location, anxiety/depression, professional support of health and well-being, coping, and defensive coping to be important for subjects' HRQOL.

CONCLUSIONS

Resilience and confounding factors were of importance in the HRQOL of subjects with COPD. Thus, consultation with a medical professional, especially at discharge, who identifies, encourages, and approves of the patient's disease management abilities will enhance both resilience and HRQOL.

A novel statistical method for assessing effective adherence to medication and calculating optimal drug dosages

OBJECTIVE

We derive a novel model-based metric for effective adherence to medication, and validate it using data from the INhaler Compliance Assessment device (INCATM). This technique employs dose timing data to estimate the threshold drug concentration needed to maintain optimal health.

METHODS

The parameters of the model are optimised against patient outcome data using maximum likelihood methods. The model is fitted and validated by secondary analysis of two independent datasets from two remote-monitoring studies of adherence, conducted through clinical research centres of 5 Irish hospitals. Training data came from a cohort of asthma patients (~ 47,000 samples from 218 patients). Validation data is from a cohort of 204 patients with COPD recorded between 2014 and 2016.

RESULTS

The time above threshold measure is strongly predictive of adverse events (exacerbations) in COPD patients (Odds Ratio of exacerbation = 0.52 per SD increase in adherence, 95% Confidence Interval [0.34-0.79]). This compares well with the best known previous method, the Area Under the dose-time Curve (AUC) (Odds Ratio = 0.69, 95% Confidence Interval [0.48-0.99]). In addition, the fitted value of the dose threshold (0.56 of prescribed dosage) suggests that prescribed doses may be unnecessarily high given good adherence.

CONCLUSIONS

The resulting metric accounts for missed doses, dose-timing errors, and errors in inhaler technique, and provides enhanced predictive validity in comparison to previously used measures. In addition, the method allows us to estimate the correct dosage required to achieve the effect of the medication using the patients' own adherence data and outcomes. The adherence score does depend not on sex or other demographic factors suggesting that effective adherence is driven by individual behavioural factors.

Physical activity in the morning and afternoon is lower in patients with chronic obstructive pulmonary disease with morning symptoms

Background

Patients with chronic obstructive pulmonary disease (COPD) experience symptoms that vary over the day. Symptoms at the start of the day might influence physical activity during the rest of the day. Therefore, physical activity during the course of the day was studied in patients with low and high morning symptom scores.

Methods

This cross-sectional observational study included patients with moderate to very severe COPD. Morning symptoms were evaluated with the PRO-morning COPD Symptoms Questionnaire (range 0–60); the median score was used to create two groups (low and high morning symptom scores). Physical activity was examined with an accelerometer. Activity parameters during the night, morning, afternoon and evening were compared between patients with low and high morning symptom scores using independent t-tests or Mann-Whitney U tests.

Results

Seventy nine patients were included. Patients were aged (mean ± SD) 65.6 ± 8.8 years with a mean forced expiratory volume in 1 s of 55 ± 17%predicted. Patients with low morning symptom scores (score < 17.0) took more steps in the afternoon (p = 0.015) and morning (p = 0.030). There were no significant differences during the evening and night.

Conclusion

Patients with high morning symptom scores took significantly fewer steps in the morning and afternoon than those with low morning symptom scores. Prospective studies are needed to prove causality between morning symptoms and physical activity during different parts of the day.

Dokumentiranje navodil o življenjskem slogu in samoobvladovanju bolezni pri pacientih s kronično obstruktivno pljučno boleznijo

Uvod: Za boljše doseganje kakovosti življenja pacientov s kronično obstruktivno pljučno boleznijo je slednje treba poučiti o značilnostih bolezni ter o ukrepih za njeno učinkovito samoobvladovanje. Namen raziskave je bil ugotoviti pogostost dokumentiranja in vrsto dokumentiranih navodil o življenjskem slogu in samoobvladovanju bolezni v bolnišnični dokumentaciji pacientov s kronično obstruktivno pljučno boleznijo.Metode: Izvedena je bila retrospektivna kvantitativna raziskava, v kateri je bila pregledana celotna bolnišnična dokumentacija (terapevtski listi, liste zdravstvene nege, arhivi zdravstvenovzgojnih šol, odpustna pisma) 253 pacientov s kronično obstruktivno pljučno boleznijo. Za analizo podatkov sta bila poleg osnovne deskriptivne statistike uporabljena tudi hi-kvadrat test in ordinalna logistična regresija.Rezultati: V bolnišnični dokumentaciji so pacienti s kronično obstruktivno pljučno boleznijo imeli dokumentirana v povprečju manj kot 4 navodila o življenjskem slogu in samoobvladovanju bolezni (x = 3,8, s = 5,1). V odpustnem pismu je polovica pacientov (x = 0,5, s = 0,9) imela zabeleženih manj navodil o življenjskem slogu in samoobvladovanju bolezni kot v bolnišnični dokumentaciji (x2 = 33,455, p < 0,001). Diplomirane medicinske sestre so navodila dokumentirale petkrat pogosteje kot zdravniki.Diskusija in zaključek: Raziskava je za bolnišnično dokumentacijo pacientov s kronično obstruktivno pljučno boleznijo ugotovila nizko število dokumentiranih navodil o življenjskem slogu in samoobvladovanju bolezni. Treba bo povečati ozaveščenost o pomenu dokumentiranja zdravstvenovzgojnih navodil in oblikovati orodja za izboljšanje medpoklicne komunikacije.

Home-based telerehabilitation in older patients with chronic obstructive pulmonary disease and heart failure: a randomised controlled trial

Background

chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) frequently coexist in older people, reducing patients' quality of life (QoL) and increasing morbidity and mortality.

Objective

we studied the feasibility and efficacy of an integrated telerehabilitation home-based programme (Telereab-HBP), 4 months long, in patients with combined COPD and CHF. The primary outcome was exercise tolerance evaluated at the 6-min walk test (6MWT). Secondary outcomes were time-to-event (hospitalisation and death), dyspnoea (MRC), physical activity profile (PASE), disability (Barthel) and QoL (MLHFQ and CAT).

Study design

randomised, open, controlled, multicenter trial.

Methods

the Telereab-HBP included remote monitoring of cardiorespiratory parameters, weekly phone-calls by the nurse, and exercise programme, monitored weekly by the physiotherapist. All outcomes were studied again after 2 months of a no-intervention period.

Results

in total, 112 patients were randomised, 56 per group. Their mean (SD) age was 70 (9) years, and 92 (82.1%) were male. After 4 months, the IG were able to walk further than at baseline: mean (95% CI) Δ6MWT was 60 (22.2,97.8) m; the CG showed no significant improvement: -15 (-40.3,9.8) m; P = 0.0040 between groups. In IG, the media time to hospitalisation/death was 113.4 days compared with 104.7 in the CG (P = 0.0484, log-rank test). Other secondary outcomes: MRC (P = 0.0500), PASE (P = 0.0015), Barthel (P = 0.0006), MLHFQ (P = 0.0007) and CAT (P = 0.0000) were significantly improved in the IG compared with the CG at 4 months. IG maintained the benefits acquired at 6 months for outcomes.

Conclusions

this 4-month Telereab-HBP was feasible and effective in older patients with combined COPD and CHF.

Counseling for health behavior change in people with COPD: systematic review

Counseling has been suggested as a promising approach for facilitating changes in health behavior. The aim of this systematic review of counseling interventions for people with COPD was to describe: 1) counseling definitions, 2) targeted health behaviors, 3) counseling techniques and 4) whether commonalities in counseling techniques were associated with improved health behaviors. Ten databases were searched for original randomized controlled trials which included adults with COPD, used the term "counseling" as a sole or component of a multifaceted intervention and were published in the previous 10 years. Data extraction, study appraisal and coding for behavior change techniques (BCTs) were completed by two independent reviewers. Data were synthesized descriptively, with meta-analysis conducted where possible. Of the 182 studies reviewed as full-text, 22 were included. A single study provided a definition for counseling. Two key behaviors were the main foci of counseling: physical activity (n=9) and smoking cessation (n=8). Six studies (27%) reported underlying models and/or theoretical frameworks. Counseling was the sole intervention in 10 studies and part of a multicomponent intervention in 12. Interventions targeting physical activity included a mean of 6.3 (±3.1) BCTs, smoking cessation 4.9 (±2.9) BCTs and other behaviors 6.5 (±3.9) BCTs. The most frequent BCTs were social support unspecified (n=22; 100%), goal setting behavior (n=11), problem-solving (n=11) and instructions on how to perform the behavior (n=10). No studies shared identical BCT profiles. Counseling had a significant positive effect for smoking cessation and positive but not significant effect for physical activity. Counseling for health behavior change was rarely defined and effectiveness varied by target behavior. Provision of specific details when reporting studies of counseling interventions (definition, BCTs, dosage) would allow clarification of the effectiveness of counseling as an approach to health behavior change in people with COPD.

COPD patients' self-reported adherence, psychosocial factors and mild cognitive impairment in pulmonary rehabilitation

In addition to clinical comorbidities, psychological and neuropsychological problems are frequent in COPD and may affect pulmonary rehabilitation delivery and outcome. The aims of the study were to describe a COPD population in a rehabilitative setting as regards the patients depressive symptoms, anxiety, mild cognitive impairment (MCI) and self-reported adherence and to analyze their relationships; to compare the COPD sample MCI scores with normative data; and to investigate which factors might predict adherence to prescribed physical exercise. This was a multicenter observational cross-sectional study. Of the 117 eligible stable COPD inpatients, 84 were enrolled according to Global initiative for chronic Obstructive Lung Disease (GOLD) criteria (mainly in Stage III-IV). The assessment included Mini Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA), anxiety, depression and self-reported pharmacological and nonpharmacological adherence. From the MMSE, 3.6% of patients were found to be impaired, whereas from the MoCA 9.5% had a likely MCI. Patients referred had mild-severe depression (46.7%), anxiety (40.5%), good pharmacological adherence (80.3%) and difficulties in following prescribed diet (24.1%) and exercise (51.8%); they struggled with disease acceptance (30.9%) and disease limitations acceptance (28.6%). Most of them received good family (89%) or social (53%) support. Nonpharmacological adherence, depression, anxiety and MCI showed significant relations with 6-minute walking test, body mass index (BMI) and GOLD. Depression was related to autonomous long-term oxygen therapy modifications, disease perception, family support and MCI. In the multivariate logistic regression analysis, higher BMI, higher depression and lower anxiety predicted lower adherence to exercise prescriptions (P=0.0004, odds ratio =0.796, 95% CI =0.701, 0.903; P=0.009, odds ratio =0.356, 95% CI =0.165, 0.770; and P=0.05, odds ratio =2.361, 95% CI =0.995, 5.627 respectively). In COPD patients, focusing on pharmacological and nonpharmacological adherence enhance the possibility of tailored pulmonary rehabilitation programs.

Self-rated health aspects among persons living with chronic obstructive pulmonary disease

Purpose

To describe a cohort of chronic obstructive pulmonary disease (COPD) patients and perform a within-group comparison regarding self-management activation, social provision, and health status.

Patients and methods

A cross-sectional survey including 116 persons.

Results

The sample comprised 65 men and 38 women, mean age 69 years. Fourteen percent reported very high impact of COPD on their health; 19% had received pulmonary rehabilitation offers, 39% had been offered self-management education, and 64% had acute hospital admissions due to COPD complications in the past year. Persons with COPD Assessment Test (CAT) scores ≥30 reported significantly poorer self-management activation and significantly lower social provision than those reporting CAT scores <30. Number of COPD years had no significant influence on COPD health care consultations or self-management activation.

Conclusion

Persons with COPD reported decreasing social provision with increasing COPD years and poorer health status. Although COPD is a progressive disease, health status and self-management activation did not vary with number of COPD years. Those living with a very high COPD impact on health reported significantly lower self-management activation but fewer acute hospital admissions.

Practice implications

COPD patients’ need for pulmonary rehabilitation, self-management support, and social support should be assessed and appropriate services offered throughout the disease trajectory.

Screening tools for evaluation of depression in Chronic Obstructive Pulmonary Disease (COPD). A systematic review

Background: Anxiety and depression are common comorbid disorders in patients with chronic obstructive pulmonary disease (COPD), though estimates of their prevalence vary considerably. Depressive symptoms/depression are important comorbidities in COPD and an increasing interest is shown to these disorders. Depression may lead to reduced quality of life and increased morbidity and mortality. These statements underline the importance of implementing the use of screening instruments for depressive symptoms in a clinical setting. This systematic review evaluates four commonly used screening tools for depression in COPD. Furthermore we assess the prevalence of depression in COPD in the evaluated studies. Design: A literature search identified studies dealing with screening for depression in patients with COPD. We focused on the instruments: Beck Depression Inventory, Geriatric depression scale, Centre for Epidemiological Studies scale on Depression and Hospital and Anxiety Depression Scale. Results: Overall prevalence of depression was 30%. Demographic variations and severity of COPD influenced prevalence. The inter-prevalence of the four screening tools was consistent. We found a low variation between studies using the same tool. Few studies used control groups or compared the screening tool to a psychiatrist evaluation. Conclusions: This article calls for further investigation of the association between COPD and depressive symptoms. The subject is highly relevant for everyday life of patients with COPD and attention needs to be drawn to this issue in both an out- and in-patients.

Home telemonitoring for patients with acute exacerbation of chronic obstructive pulmonary disease: a randomized controlled trial

Background

Although a number of studies have suggested that the use of Telemonitoring (TM) in patients with Chronic Obstructive Pulmonary Disease (COPD) can be useful and efficacious, its real utility in detecting Acute Exacerbation (AE) signaling the need for prompt treatment is not entirely clear. The current study aimed to investigate the benefits of a TM system in managing AE in advanced-stage COPD patients to improve their Health-Related Quality of Life (HRQL) and to reduce utilization of healthcare services.

Methods

A 12-month Randomised Controlled Trial (RCT) was conducted in the Veneto region (Italy). Adult patients diagnosed with Class III-IV COPD in accordance with the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification were recruited and provided a TM system to alert the clinical staff via a trained operator whenever variations in respiratory parameters fell beyond the individual’s normal range. The study’s primary endpoint was HRQL, measured by the Italian version of the two Short Form 36-item Health Survey (SF36v2). Its secondary endpoints were: scores on the Hospital Anxiety and Depression Scale (HADS); the number and duration of hospitalizations; the number of readmissions; the number of appointments with a pulmonary specialist; the number of visits to the emergency department; and the number of deaths.

Results

Three hundred thirty-four patients were enrolled and randomized into two groups for a 1 year period. At its conclusion, changes in the SF36 Physical and Mental Component Summary scores did not significantly differ between the TM and control groups [(-2.07 (8.98) vs -1.91 (7.75); p = 0.889 and -1.08 (11.30) vs -1.92 (10.92); p = 0.5754, respectively]. Variations in HADS were not significantly different between the two groups [0.85 (3.68) vs 0.62 (3.6); p = 0.65 and 0.50 (4.3) vs 0.72 (4.5); p = 0.71]. The hospitalization rate for AECOPD and/or for any cause was not significantly different in the two groups [IRR = 0.89 (95% CI 0.79–1,04); p = 0.16 and IRR = 0.91 (95% CI 0,75 – 1.04); p = 0.16, respectively]. The readmission rate for AECOPD and/or any cause was, however, significantly lower in the TM group with respect to the control one [IRR = 0.43 (95% CI 0.19–0.98); p = 0.01 and 0.46 (95% CI 0.24–0.89); p = 0.01, respectively].

Conclusion

Study results showed that in areas where medical services are well established, TM does not significantly improve HRQL in patients with COPD who develop AE. Although not effective in reducing hospitalizations, TM can nevertheless facilitate continuity of care during hospital-to-home transition by reducing the need for early readmission.

External validation of multidimensional prognostic indices (ADO, BODEx and DOSE) in a primary care international cohort (PROEPOC/COPD cohort)

BACKGROUND

Due to the heterogeneous and systemic nature of the chronic obstructive pulmonary disease (COPD), the new guidelines are oriented toward individualized attention. Multidimensional scales could facilitate its proper clinical and prognostic assessment, but not all of them were validated in an international primary care cohort, different from the original ones used for model development. Therefore, our main aim is to assess the prognostic capacity of the ADO, BODEx and DOSE indices in primary care for predicting mortality in COPD patients and to validate the models obtained in subgroups of patients, classified by revised Global Initiative for Chronic Obstructive Lung Disease (2011) and updated Spanish Guideline (2014). Besides, we want to confirm that the prognostic capacity of all indices increases if the number of exacerbations is substituted by the interval between them and to assess the impact on health of the patient's lifestyle, social network and adherence to treatment.

METHODS

Design: External validation of scales, open and prospective cohort study in primary care.

SETTING

36 health centres in 6 European high, medium and low income countries.

SUBJECTS

477 patients diagnosed with COPD, captured in clinical visit by their General Practitioner/Nurse.

PREDICTORS

Detailed patient history, exacerbations, lung function test and questionnaires at baseline.

OUTCOMES

Exacerbations, all-cause mortality and specific mortality, within 5 years of recruitment.

ANALYSIS

Multivariate logistic regression and Cox regression will be used. Possible non-linear effect of the indices will be studied by using Structured Additive Regression models with penalised splines. Subsequently, we will assess different aspects of the regression models: discrimination, calibration and diagnostic precision. Clinical variables modulated in primary care and the interval between exacerbations will be considered and incorporated into the analysis.

DISCUSSION

The Research Agenda for General Practice/Family Medicine highlights that the evidence on predictive values of prognostic indices in primary care is scarce. A prospective cohort like that of PROEPOC/COPD provides good opportunities for research into COPD and make communication easier between family practitioners, nursing staff, pneumologists and other professionals, supporting a multi-disciplinary approach to the treatment of these patients.

A multidisciplinary telehealth program in patients with combined chronic obstructive pulmonary disease and chronic heart failure: study protocol for a randomized controlled trial

BACKGROUND

Chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF) frequently coexist, significantly reducing patients' quality of life and increasing morbidity and mortality. For either single disease, a multidisciplinary disease-management approach supported by telecommunication technologies offers the best outcome in terms of prolonged survival and reduced hospital readmissions. However, no data exist in patients with combined COPD/CHF. We planned a randomized controlled trial to investigate the feasibility and efficacy of an integrated, home-based, medical/nursing intervention plus a rehabilitation program versus conventional care in patients with coexisting COPD/CHF. The purpose of the paper is to describe the rationale and design of the trial.

METHODS/DESIGNS

Patients, after inpatient rehabilitation, were randomly assigned to the intervention or control group, followed for 4 months at home, then assessed at 4 and 6 months. The intervention group followed a telesurveillance (telephone contacts by nurse and remote monitoring of cardiorespiratory parameters) and home-based rehabilitation program (at least three sessions/week of mini-ergometer exercises, callisthenic exercises and twice weekly pedometer-driven walking, plus telephone contacts by a physiotherapist). Telephone follow-up served to verify compliance to therapy, maintain exercise motivation, educate for early recognition of signs/symptoms, and verify the skills acquired. At baseline and 4 and 6 months, the 6-min Walk Test, dyspnea and fatigue at rest, oxygenation (PaO2/FiO2), physical activity profile (PASE questionnaire), and QoL (Minnesota and CAT questionnaires) were assessed. During the study, serious clinical events (hospitalizations or deaths) were recorded.

DISCUSSION

Currently, no studies have assessed the impact of a telehealth program in patients with combined COPD and CHF. Our study will show whether this approach is effective in the management of such complex, frail patients who are at very high risk of exacerbations.

Assessing the effect of culturally specific audiovisual educational interventions on attaining self-management skills for chronic obstructive pulmonary disease in Mandarin- and Cantonese-speaking patients: a randomized controlled trial

BACKGROUND

Patient education is a key component in the management of chronic obstructive pulmonary disease (COPD). Delivering effective education to ethnic groups with COPD is a challenge. The objective of this study was to develop and assess the effectiveness of culturally and linguistically specific audiovisual educational materials in supporting self-management practices in Mandarin- and Cantonese-speaking patients.

METHODS

Educational materials were developed using participatory approach (patients involved in the development and pilot test of educational materials), followed by a randomized controlled trial that assigned 91 patients to three intervention groups with audiovisual educational interventions and one control group (pamphlet). The patients were recruited from outpatient clinics. The primary outcomes were improved inhaler technique and perceived self-efficacy to manage COPD. The secondary outcome was improved patient understanding of pulmonary rehabilitation procedures.

RESULTS

Subjects in all three intervention groups, compared with control subjects, demonstrated postintervention improvements in inhaler technique (P<0.001), preparedness to manage a COPD exacerbation (P<0.01), ability to achieve goals in managing COPD (P<0.01), and understanding pulmonary rehabilitation procedures (P<0.05).

CONCLUSION

Culturally appropriate educational interventions designed specifically to meet the needs of Mandarin and Cantonese COPD patients are associated with significantly better understanding of self-management practices. Self-management education led to improved proper use of medications, ability to manage COPD exacerbations, and ability to achieve goals in managing COPD.

CLINICAL IMPLICATION

A relatively simple culturally appropriate disease management education intervention improved inhaler techniques and self-management practices. Further research is needed to assess the effectiveness of self-management education on behavioral change and patient empowerment strategies.

Risk stratification for COPD diagnosis through an active search strategy in primary care

Background

The aim of this study was to identify the percentage of undiagnosed patients with COPD through the implementation of an active search strategy in a selected subject population.

Methods

An observational, cross-sectional, multicenter study was conducted in a primary care setting in Spain. General practitioners gave their diagnostic impression of COPD (yes/no) on the basis of clinical criteria of subjects with respiratory symptoms and tobacco exposure. Subsequently, post-bronchodilator spirometry and quality-of-life tests were performed. Multivariate logistic regression techniques using receiver operating characteristic (ROC) curves were used to identify the combination of variables that best discriminates COPD.

Results

A total of 2,758 patients were screened at 368 primary care centers, of which 1,725 patients were included in the study. Seven hundred and ninety-three patients (46%) were diagnosed with COPD. Clinical judgment resulted in suspected COPD in 1,393 (81%) of the subjects. The best variables to discriminate COPD were a history of lower respiratory tract infections, cough, and dyspnea. This combination identified COPD with a ROC_AUC of 0.61 denoting a poor discriminative ability.

Conclusion

Employing an active search strategy leads to a new COPD diagnosis in almost half of the subjects. Screening of COPD with post-bronchodilator spirometry should be considered mandatory for any high-risk subject visiting the general practitioner clinic for any reason.

Strategies to improve anxiety and depression in patients with COPD: a mental health perspective

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease characterized by progressive and only partially reversible symptoms. Worldwide, the incidence of COPD presents a disturbing continuous increase. Anxiety and depression are remarkably common in COPD patients, but the evidence about optimal approaches for managing psychological comorbidities in COPD remains unclear and largely speculative. Pharmacological treatment based on selective serotonin reuptake inhibitors has almost replaced tricyclic antidepressants. The main psychological intervention is cognitive behavioral therapy. Of particular interest are pulmonary rehabilitation programs, which can reduce anxiety and depressive symptoms in these patients. Although the literature on treating anxiety and depression in patients with COPD is limited, we believe that it points to the implementation of personalized strategies to address their psychopathological comorbidities.

Comorbidities associated with COPD in the Middle East and North Africa region: association with severity and exacerbations

OBJECTIVE

To assess the frequency of comorbidities in subjects with COPD and their association with respiratory symptom severity and COPD exacerbations.

MATERIALS AND METHODS

This was an analysis of the BREATHE study, a cross-sectional survey of COPD conducted in the general population of eleven countries in the Middle East and North Africa, including Pakistan. The study population consisted of a sample of subjects with COPD for whom the presence of comorbidities was documented. Three questionnaires were used. The screening questionnaire identified subjects who fulfilled an epidemiological case definition of COPD and documented any potential comorbidities; the detailed COPD questionnaire collected data on respiratory symptoms, COPD exacerbations, and comorbidities associated with COPD; the COPD Assessment Test collected data on the impact of respiratory symptoms on well-being and daily life.

RESULTS

A total of 2,187 subjects were positively screened for COPD, of whom 1,392 completed the detailed COPD questionnaire. COPD subjects were more likely to report comorbidities (55.2%) than subjects without COPD (39.1%, P<0.0001), most frequently cardiovascular diseases. In subjects who screened positively for COPD, the presence of comorbidities was significantly (P=0.03) associated with a COPD Assessment Test score ≥10 and with antecedents of COPD exacerbations in the previous 6 months (P=0.03).

CONCLUSION

Comorbidities are frequent in COPD and associated with more severe respiratory symptoms. This highlights the importance of identification and appropriate management of comorbidities in all subjects with a diagnosis of COPD.

Exploring the Unmet Needs of the Patients in the Outpatient Respiratory Medical Clinic: Patients versus Clinicians Perspectives

Aim. Developing a theoretical framework explaining patients' behaviour and actions related to unmet needs during interactions with health care professionals in hospital-based outpatient respiratory medical clinics. Background. The outpatient respiratory medical clinic plays a prominent role in many patients' lives regarding treatment and counselling increasing the need for a better understanding of patients' perspective to the counselling of the health care professionals. Design. The study is exploratory and based on Charmaz's interpretation of grounded theory. Methods. The study included 65 field observations with a sample of 43 patients, 11 doctors, and 11 nurses, as well as 30 interviews with patients, conducted through theoretical sampling from three outpatient respiratory medical clinics in Denmark. Findings. The patients' efforts to share their significant stories triggered predominantly an adaptation or resistance behaviour, conceptualized as "fitting in" and "fighting back" behaviour, explaining the patients' counterreactions to unrecognized needs during the medical encounter. Conclusion. Firstly this study allows for a better understanding of patients' counterreactions in the time-pressured and, simultaneously, tight structured guidance program in the outpatient clinic. Secondly the study offers practical and ethical implications as to how health care professionals' attitudes towards patients can increase their ability to support emotional suffering and increase patient participation and responsiveness to guidance in the lifestyle changes.

Chronic obstructive lung disease and posttraumatic stress disorder: current perspectives

Background

Several studies have reported on the co-occurrence of chronic obstructive pulmonary disease (COPD) and psychiatric conditions, with the most robust evidence base demonstrating an impact of comorbid anxiety and depression on COPD-related outcomes. In recent years, research has sought to determine if there is a co-occurrence between COPD and posttraumatic stress disorder (PTSD) as well as for associations between PTSD and COPD-related outcomes. To date, there have been no published reviews summarizing this emerging literature.

Objectives

The primary objective of this review was to determine if there is adequate evidence to support a co-occurrence between PTSD and COPD. Secondary objectives were to: 1) determine if there are important clinical considerations regarding the impact of PTSD on COPD management, and 2) identify targeted areas for further research.

Methods

A structured review was performed using a systematic search strategy limited to studies in English, addressing adults, and to articles that examined: 1) the co-occurrence of COPD and PTSD and 2) the impact of PTSD on COPD-related outcomes. To be included, articles must have addressed some type of nonreversible obstructive lung pathology.

Results

A total of 598 articles were identified for initial review. Upon applying the inclusion and exclusion criteria, n=19 articles or abstracts addressed our stated objectives. Overall, there is inconclusive evidence to support the co-occurrence between PTSD and COPD. Studies finding a significant co-occurrence generally had inferior methods of identifying COPD; in contrast, studies that utilized more robust COPD measures (such as a physician exam) generally failed to find a relationship. Among studies that examined the impact of PTSD on COPD-related outcomes, there was more consistent evidence that PTSD affects the perception of respiratory symptom burden and management. In addition, methods for measuring an important confounder (smoking) were generally lacking.

Conclusion

There is inconclusive evidence to support the co-occurrence of COPD and PTSD. There was stronger evidence implicating PTSD as an important comorbidity impacting COPD management. Further research is needed to: 1) determine whether or not COPD and PTSD are likely to be comorbid, and 2) further elucidate the mechanisms connecting PTSD and COPD-related outcomes.

Determinants of health-related quality of life among residents with and without COPD in a historically industrialised area

Purpose

Chronic obstructive pulmonary disease (COPD) is associated with substantial morbidity, including impaired health-related quality of life (HRQoL). Despite the prominent role of occupational factors in the aetiology of COPD, the relationship between these exposures and HRQoL has not been well elucidated.

Methods

A subpopulation from an epidemiological study, designed to assess the workplace contribution to COPD, was administered the EQ5D HRQoL tool. Demographics, an index of economic deprivation, health endpoints including the presence of COPD and lung function were also recorded. Workplace exposures were categorised using both self-reported exposures and also by the use of an established job exposure matrix (JEM).

Results

A total of 623 individuals participated (mean age 67.1 years). One hundred and forty-eight (24 %) reported having received a physician diagnosis of COPD, 355 (57 %) were male, and 386 (62 %) were ever smokers. As anticipated, the presence of COPD was associated with a poorer HRQoL. Additionally, however, HRQoL was significantly lower in the presence of both self-reported vapours, gases, dusts and fumes exposure and JEM-based exposure irrespective of the presence of COPD. Regression analysis, adjusting for a variety of covariates including the presence of COPD, confirmed a persisting higher likelihood of occupational exposure categorised by JEM being associated with poorer HRQoL scores (β estimate: −0.069; p < 0.05).

Conclusions

Our findings suggest that work may have an important link to HRQoL and that this effect can persist even among those who have retired. In those with COPD, HRQoL is worse than among those without this condition, but the work-associated decrement appears to be similar across both groups.

Utilization of smoking-cessation pharmacotherapy among chronic obstructive pulmonary disease (COPD) and lung cancer patients

OBJECTIVE

Smoking is one of the major risk factors causing morbidity and mortality in chronic obstructive pulmonary disease (COPD) and lung cancer patients. Use of smoking cessation pharmacotherapy is an effective way to help quit smoking. The purpose of the study was to determine the prevalence of smoking and the proportion of patients using smoking cessation agents, and to identify the socio-demographic factors that affect the use of these agents among COPD and lung cancer patients.

RESEARCH DESIGN AND METHODS

A retrospective study was done to identify smokers having COPD (ICD-9: 490-492) or lung cancer (ICD-9: 162), and those who use smoking cessation agents from 2006-2010, using Medical Expenditure Panel Survey (MEPS) data. A multiple logistic regression model was built to identify significant socio-demographic predictors associated with the use of smoking cessation agents.

RESULTS

Around 16.8% of COPD patients and 15.1% of lung cancer patients reported smoking after diagnosis. Out of the total smokers, 8.8% patients with COPD and 12.6% patients with lung cancer reported use of smoking cessation agents during the 5 year period. Logistic regression showed that odds for smoking cessation use in COPD patients were lower for Hispanics (OR = 0.107, 95% CI 0.023-0.502) and higher for patients having insurance coverage (OR = 3.453, 95% CI 1.240-9.617).

CONCLUSION

Results showed that a large number of patients continued to smoke even after the diagnosis of COPD and lung cancer; whereas only a few among them used smoking cessation agents. Ethnicity disparities and insurance status were associated with the use of smoking cessation agents. Differential use among population sub-groups suggests a requirement for need based smoking cessation programs and appropriate prescription drug coverage. Further research needs to be done to evaluate reasons for disparities in smoking cessation agents' use. The study had limitations common to research designs based on observational and self-reported datasets.

A 1-year follow-up study exploring the associations between perception of illness and health-related quality of life in persons with chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is a progressive respiratory disease with an increasing prevalence worldwide. Its potential consequences, including reduced function and reduced social participation, are likely to be associated with decreased health-related quality of life (HRQoL). However, illness perceptions and self-efficacy beliefs may also play a part in determining HRQoL in persons with COPD. The aim of this study was to explore the relationships between illness perceptions, self-efficacy, and HRQoL in a sample of persons with COPD in a longitudinal perspective. The context of the study was a patient education course from which the participants were recruited. Data concerning sociodemographic variables, social support, physical activity, illness perceptions, general self-efficacy, and HRQoL were collected before the course started and 1 year after completion. Linear regression was used in the analyses. The results showed that less consequences and less symptoms (identity) were associated with higher physical HRQoL (PCS) at baseline and at 1-year follow-up. Less emotional response was similarly associated with higher mental HRQoL (MCS) at both time points. Lower self-efficacy showed a borderline significant association with higher PCS at baseline, but was unrelated to MCS at both time points. Self-efficacy showed no influence on the associations between illness perceptions and HRQoL. In conclusion, the study showed that specific illness perceptions had a stable ability to predict HRQoL in persons with COPD, whereas self-efficacy did not. The associations between illness perceptions and HRQoL were not mediated by self-efficacy.
