Background: Poor adherence to inhaled medication may lead to inadequate symptom control in patients with respiratory disease. In practice it can be difficult to identify poor adherence. We designed an acoustic recording device, the INCA® (INhaler Compliance Assessment) device, which, when attached to an inhaler, identifies and records the time and technique of inhaler use, thereby providing objective longitudinal data on an individual's adherence to inhaled medication. This study will test the hypothesis that providing objective, personalised, visual feedback on adherence to patients in combination with a tailored educational intervention in a community pharmacy setting, improves adherence more effectively than education alone., Methods/design: The study is a prospective, cluster randomised, parallel-group, multi-site study conducted over 6 months. The study is designed to compare current best practice in care (i.e. routine inhaler technique training) with the use of the INCA® device for respiratory patients in a community pharmacy setting. Pharmacies are the unit of randomisation and on enrolment to the study they will be allocated by the lead researcher to one of the three study groups (intervention, comparator or control groups) using a computer-generated list of random numbers. Given the nature of the intervention neither pharmacists nor participants can be blinded. The intervention group will receive feedback from the acoustic recording device on inhaler technique and adherence three times over a 6-month period along with inhaler technique training at each of these times. The comparator group will also receive training in inhaler use three times over the 6-month study period but no feedback on their habitual performance. The control group will receive usual care (i.e. the safe supply of medicines and advice on their use). The primary outcome is the rate of participant adherence to their inhaled medication, defined as the proportion of correctly taken doses of medication at the correct time relative to the prescribed interval. Secondary outcomes include exacerbation rates and quality of life measures. Differences in the timing and technique of inhaler use as altered by the interventions will also be assessed. Data will be analysed on an intention-to-treat and a per-protocol basis. Sample size has been calculated with reference to comparisons to be made between the intervention and comparator clusters and indicates 75 participants per cluster. With an estimated 10 % loss to follow-up we will be able to show a 20 % difference between the population means of the intervention and comparator groups with a power of 0.8. The Type I error probability associated with the test of the null hypothesis is 0.05., Discussion: This clinical trial will establish whether providing personalised feedback to individuals on their inhaler use improves adherence. It may also be possible to enhance the role of pharmacists in clinical care by identifying patients in whom alteration of either therapy or inhaler device is appropriate., Registration: ClinicalTrials.gov NCT02203266 .

Objective: To evaluate self-esteem and self-image of respiratory diseases patients in a Pulmonary Rehabilitation Program, who participated in socialization and physical fitness activities, and of patients who participated only in physical fitness sessions., Methods: A descriptive cross-sectional exploratory study. Out of a total of 60 patients analyzed, all enrolled in the Pulmonary Rehabilitation Program, 42 participated in at least one of the proposed activities, 10 did not participate in any activity and 8 were excluded (7 were discharged and 1 died)., Results: When the two groups were compared, despite the fact that both demonstrated low self-esteem and self-image, the difference between them was relevant (p<0.05) regarding self-esteem, indicating that those who participated in the proposed socialization activities had better self-esteem than the individuals who only did the physical fitness sessions. Regarding self-image, the difference between the groups was not relevant (p>0.05)., Conclusion: The Pulmonary Rehabilitation Program patients evaluated presented low self-esteem and self-image; however, those carrying out some socialization activity proposed had better self-esteem as compared to the individuals who did only the physical fitness sessions.

Objectives: To compare domains of cognitive functioning between persons with and without obstructive lung disease (OLD) and to analyze the relationship between cognitive functioning and the degree of airflow limitation., Design: An observational population-based study., Setting: This research was conducted using the United Kingdom Biobank Resource., Participants: The study population consisted of 43,039 persons with complete data on cognitive functioning and spirometry., Measurements: Cognitive functioning was compared between persons with and without OLD using linear regression analysis. The relationship between impairment in lung function and cognitive impairment was assessed among persons with OLD., Results: Persons with OLD had significantly worse scores than persons without OLD on prospective memory [β = -0.15 (-0.22 to -0.09)], visuospatial memory [β round 1 = 0.06 (0.03‒0.10)]; β round 2 = 0.09 (<0.001‒0.18)), numeric short-term memory [β = ‒0.05 (‒0.10 to <0.001)] and cognitive processing speed [β = 4.62 (1.25‒8.01)] after correction for possible confounders. Impairment in prospective memory [β = 0.004 (<0.001‒0.01)] and numeric short-term memory [β = 0.01 (0.003‒0.01)] were weakly related to FEV1 (adjusted P < .05)., Conclusions: Persons with OLD experience cognitive impairment in different domains, which is partially related to airway obstruction. In particular, memory and information processing are affected. Further assessment of the relationship with patient-related outcomes is needed to optimize patient-oriented treatment., (Copyright © 2014. Published by Elsevier Inc.)

Background: Chronic obstructive pulmonary disease (COPD) patients are confronted with reduced daily activities (DA) and reduced health-related quality of life (HRQoL) caused by dyspnea and systemic effects such as skeletal muscle dysfunction and co-morbidities. To understand the complexity of living with COPD, it is important to understand which factors, in addition to physical functioning, are associated with DA and HRQoL. In this study, we explored the extent to which the combination of illness perceptions, proactive coping, and depressive symptoms contribute to DA and HRQoL in COPD patients., Method: In a cross-sectional study in primary care, 90 COPD patients (GOLD I-III) completed questionnaires: the Brief Illness Perception Questionnaire, the Utrecht Proactive Coping Competence scale, the Centers for Epidemiologic Studies Depression scale, the Medical Research Council dyspnea scale, the Functional Performance Inventory (FPI), and the Clinical COPD Questionnaire (CCQ). The analyses were performed with multiple linear regression analyses., Results: More adequate and positive illness perceptions (β = .61, p < .001) and less depressive symptoms (β = .21, p = .010) were associated with better HRQoL (CCQ). Significant relations between psychological factors and DA were not found., Conclusion: The results of this study demonstrate that psychological factors are related to HRQoL, but not to DA. These results contribute to understanding the complexity of living with COPD and provide starting points for the development of interventions focusing on psychological factors to support COPD patients in disease management.

Background: The opinions held by the general population on obstructive lung disease and inhaler devices could influence asthma and chronic obstructive pulmonary disorder (COPD) management and treatment adherence.The aim of the present public pragmatic survey was to evaluate the opinions, beliefs and perceptions of Italian people with respect to respiratory diseases as well as their perspectives on the use of inhaler devices., Methods: This survey was conducted on a group of 2,008 individuals forming a representative sample of the Italian population aged 15 years and over. It was based on personal interviews that were administered in the homes of the respondents using a structured questionnaire that took approximately 30 minutes., Results: Awareness of obstructive lung diseases is poor. Asthma, but not COPD, was perceived as a common and increasingly prevalent disease by the majority of the interviewees. Allergy, pollution and smoking were considered to be responsible for both of these diseases. The rates at which the respondents claimed to be suffering from asthma and COPD were lower than expected (4% and 2%, respectively). Inhaled drugs were recognised as the main treatment by 65% of the respondents. The great majority of respondents attributed positive characteristics to the inhaler device (e.g., safety, reliability, effectiveness, ease of use and practicality). Compared to people who have never used inhaler devices, individuals who suffer from asthma or COPD were more confident in their use and showed a greater belief in their safety, reliability and trustworthiness. People older than 64 years showed less attention to the properties of these devices., Conclusions: The present results highlight the need for public interventions aimed at improving awareness of obstructive lung disease and reveal various potentialities and critical issues for inhaler device usage. Switching of devices was considered feasible by most of the interviewees, as long as the choice is carefully explained by their physician.

Purpose: This study aimed to validate the Activities and Participation component of the Comprehensive International Classification of Functioning, Disability and Health (ICF) Core Set for Obstructive Pulmonary Diseases (OPD) from the patient's perspective., Methods: A cross-sectional qualitative study was conducted with a convenience sample of outpatients with Chronic Obstructive Pulmonary Disease (COPD). Individual interviews were performed and analysed according to the meaning condensation procedure., Results: Fifty-one participants (70.6% male) with a mean age of 69.5 ± 10.8 years old were included. Twenty-one of the 24 categories contained in the Activities and Participation component of the Comprehensive ICF Core Set for OPD were identified by the participants. Additionally, seven second-level categories that are not covered by the Core Set were reported: complex interpersonal interactions, informal social relationships, family relationships, conversation, maintaining a body position, eating and preparing meals., Conclusions: The activities and participation component of the ICF Core Set for OPD was largely supported by the patient's perspective. The categories included in the ICF Core Set that were not confirmed by the participants and the additional categories that were raised need to be further investigated in order to develop an instrument according to the patient's perspective. This will promote a more patient-centred assessments and rehabilitation interventions. Implications for Rehabilitation The Activities and Participation component of the Comprehensive ICF Core Set for OPD is largely supported by the perspective of patients with COPD and therefore could be used in the assessment of patients' individual and social life. The information collected through the Activities and Participation component of the Comprehensive ICF Core Set for OPD could be used to plan and assess rehabilitation interventions for patients with COPD.

Objectives:  This study sought to examine how patients' mood and quality of life (QoL) change during the early high-risk period after a diagnosis of heart failure (HF) and to identify factors that may influence change., Design:  A within-subjects, repeated-measures design was used. Assessments took place within 4 weeks of diagnosis and 6 months later., Methods:  One hundred and sixty six patients with HF completed assessments of their mood, QoL, and beliefs about HF and its treatment. Correlation analysis was conducted between the variables and analysis of variance and t-tests were used to assess differences in categorical variables. To examine which variables predicted mood and QoL, hierarchical multiple regressions were conducted., Results: At follow-up, patients' beliefs indicated a realization of the chronicity of their HF, however their beliefs about the consequences of having HF did not change and their satisfaction with their treatment remained high. QoL and anxiety improved significantly over time but there was no significant change in depressed mood. As would be expected, improvement in symptoms was a key factor in improved mood and QoL. Other significant explanatory variables included age, comorbid chronic obstructive pulmonary disease, depressed mood, patients' beliefs about the consequences of their HF and their concerns about treatment., Conclusions:  This study suggests that addressing patients' mood and beliefs about their illness and its treatment may be additional ways of improving patient QoL in the early period after the diagnosis of HF., (© 2011 The British Psychological Society.)

Background: Adoption and maintenance of healthy behaviours is pivotal to chronic disease self-management as this influences disease progression and impact. This qualitative study investigated health behaviour changes adopted by participants with moderate or severe chronic obstructive pulmonary disease (COPD) recruited to a randomised controlled study of telephone-delivered health-mentoring., Methods: Community nurses trained as health-mentors used a patient-centred approach with COPD patients recruited in general practice to facilitate behaviour change, using a framework of health behaviours; 'SNAPPS' Smoking, Nutrition, Alcohol, Physical activity, Psychosocial well-being, and Symptom management, through regular phone calls over 12 months. Semi-structured interviews in a purposive sample sought feedback on mentoring and behaviour changes adopted. Interviews were analysed using iterative thematic and interpretative content approaches by two investigators., Results: Of 90 participants allocated to health-mentoring, 65 (72%) were invited for interview at 12-month follow up. The 44 interviewees, 75% with moderate COPD, had a median of 13 mentor contacts over 12 months, range 5-20. Interviewed participants (n=44, 55% male, 43% current smokers, 75% moderate COPD) were representative of the total group with a mean age 65 years while 82% had at least one additional co-morbid chronic condition. Telephone delivery was highly acceptable and enabled good rapport. Participants rated 'being listened to by a caring health professional' as very valuable. Three participant groups were identified by attitude to health behaviour change: 14 (32%) actively making changes; 18 (41%) open to and making some changes and 12 (27%) more resistant to change. COPD severity or current smoking status was not related to group category. Mentoring increased awareness of COPD effects, helping develop and personalise behaviour change strategies, even by those not actively making changes. Physical activity was targeted by 43 (98%) participants and smoking by 14 (74%) current smokers with 21% reporting quitting. Motivation to maintain changes was increased by mentor support., Conclusions: Telephone delivery of health-mentoring is feasible and acceptable to people with COPD in primary care. Health behaviours targeted by this population, mostly with moderate disease, were mainly physical activity and smoking reduction or cessation. Health-mentoring increased motivation and assisted people to develop strategies for making and sustaining beneficial change., Trial Registration: ACTR12608000112368.

Chronic obstructive pulmonary disease (COPD), diabetes and asthma are chronic illnesses that affect a substantial number of people. The continued high cost of clinic- and hospital-based care provision in these areas could be reduced by patients self-monitoring their condition more effectively. Such a move requires an understanding of how to predict self-monitoring compliance. Ajzen's theory of planned behaviour (TPB) makes it possible to predict those clients who will comply with medical guidelines, prescription drug intake and self-monitoring behaviours (peak flow or blood sugar levels). Ninety-seven clients attending a medical centre located in a large urbanised area of Northern Ireland completed TPB questionnaires. Significant amounts of variance explained by the TPB model indicated its usefulness as a predictor of self-monitoring behaviour intentions in the sample. The results also highlighted the importance of subjective norm and perceived behavioural control within the TPB in predicting intentions. The utility of the TPB in this study also provides evidence for health promotion professionals that costly clinic/hospital treatment provision can be reduced, whilst also being satisfied with ongoing client self-monitoring of their condition.

Objective: There is cumulative evidence for a strong association of obstructive lung disease, i.e. asthma and COPD, with poor mental health, particularly with anxiety disorders and major depression. However, studies relating mental health problems to objective measures of lung function as assessed by spirometry are lacking., Methods: The 12-month prevalence of specific psychopathological syndromes among 1772 adults from the general population was estimated by a structured interview. Additionally, participants underwent spirometry and were asked about obstructive lung disease in the year prior to the study. Logistic and linear regression models were used to relate obstructive lung disease and spirometrically defined airway obstruction to mental health problems., Results: Mental health problems were found in 35.7% of the participants. After adjusted for sociodemographic, clinical and life-style factors, asthma and chronic bronchitis were associated with almost all domains of mental health problems. In contrast, independent of its definition, spirometric airflow limitation was only related to generalized anxiety (odds ratios ranging from 2.3 to 2.7). A reduced ratio of forced expiratory volume in one second to forced vital capacity was associated with mental health problems in general and panic and general anxiety in particular., Conclusion: Our findings suggest an association of objective measure of airflow limitation to generalized anxiety and panic. While the causal relationship between obstructive lung disease, airflow limitation and anxiety remains to be determined, clinicians should pay diagnostic attention to the significant overlap of these conditions., (Copyright © 2011 Elsevier Inc.

Purpose: To date, there are no studies that have investigated the role of alexithymia in respiratory rehabilitation. We aimed to observe the prevalence of alexithymia in patients attending respiratory rehabilitation and to verify the presence of a difference between alexithymics and non-alexithymics responsiveness to the respiratory rehabilitation standard protocol., Methods: A prospective cohort study evaluating the influence of alexithymia on functional recovery of in-patients afferent to the Respiratory Rehabilitation Unit of IRCCS San Raffaele Pisana. Sixty patients were consecutively enrolled into the study and evaluated for alexithymia, anxiety and depression. Functional recovery was assessed with the six-minute walking test (6MWT). Prior and post-completion of this test dyspnoea, oxygen saturation and cardiac frequency were recorded., Results: Alexithymia was not found to be significantly affecting the functional recovery of participants in respiratory rehabilitation. The distance walked at the 6MWT (6MWD) increased in both alexithymics and non-alexithymics (p(alexithymics) = 0.014; p(non-alexithymics) < 0.0001). Dyspnoea strongly improved among non-alexithymics, although a signal for improvement was also found in alexithymics (p(alexithymics) = 0.046; p(non-alexithymics) = 0.0001)., Conclusions: These findings suggest that alexithymia did not have a significant impact on functional recovery of patients in respiratory rehabilitation.

Background: Patients with obstructive sleep apnea syndrome (OSAS) are known to have an increased risk for motor vehicle crashes. They suffer from sleep-related respiratory abnormality causing repetitive arousal leading to daytime sleepiness. In turn, it has been demonstrated that sleepiness can impair human psychomotor performance causing slowing of reaction times (RTs). Patients with OSAS present with RTs comparable to young adults under the influence of blood alcohol concentrations above the legally permitted level to drive a motor vehicle. Vigilance related risk levels in patients with upper airway resistance syndrome (UARS) and potential deficits in psychomotor performance are unknown., Methods: We designed a study to compare psychomotor performance in UARS and compared it to patients with OSAS. Forty-seven UARS patients were matched by gender and age with 47 OSAS patients. All subjects completed a standardized vigilant attention task utilizing reaction time before undergoing polygraphic sleep studies., Results: Patients with UARS presented worse psychomotor performance on most test metrics than patients with OSAS., Conclusions: Our study results may suggest that patients with UARS may also present an increased risk for motor vehicle crashes as previously demonstrated in OSAS patients.

Rationale: Infradiagnosis of chronic obstructive pulmonary disease (COPD) may be related to the lack of knowledge about the disease and/or the scarce use of diagnostic procedures. This study analyses the frequency of respiratory symptoms and the knowledge about COPD in the general population, together with the use of spirometry in individuals at risk of COPD., Population and Method: A telephone survey was carried out in 6758 subjects older than 40 years, stratified by age, habitat (urban or rural) and region, screened by random-digit dialling., Results: Up to 24% reported having at least one chronic respiratory symptom and 20.9% had a self-reported respiratory diagnosis. A total of 19.2% were active smokers and 40% had never tried to quit. Only 60% of the individuals with chronic symptoms had consulted a physician and, of them, only 45% had undergone spirometry. Spirometry was mentioned more frequently by subjects attended by pulmonologists than by GPs (67.6 vs. 28.6%; P<0.001). The term COPD was identified only by 8.6% of the participants., Conclusions: Many individuals with respiratory symptoms do not request medical attention and do not attempt to quit smoking. There is a lack of knowledge about COPD. Physicians should more actively inform about the disease and increase the use of spirometry for early detection.

Panic disorder is a common illness with significant impact on function and, at times, disabling consequences. Advances over recent years have yielded potential pathophysiologic mechanisms, including neurotransmitter systems and neural substrates. This article provides an overview of various models and hypotheses regarding the etiology of panic disorder. Because its symptoms overlap with the symptoms of various medical disorders, this discussion reviews the comorbidity of panic disorder with medical conditions, especially cardiac and respiratory disorders.

Background: The Airways Questionnaire 20 (AQ20) is a concise measure of health-related quality of life (HRQL) in obstructive airway disease; however, its original format may underestimate impairment due to the complete cessation of certain activities., Methods: We revised seven items of the original AQ20 (revised AQ20 [AQ20-R]), adding response options for inability to perform certain activities. We assessed the performance of the AQ20-R among 352 adults with various airway conditions identified through a random telephone sample. Concurrent validity of the AQ20-R was assessed relative to the Short Form-12 (SF-12) physical component summary (PCS), FEV(1), and medication use. Predictive validity was assessed relative to health-care utilization among 278 subjects studied longitudinally., Results: Twenty-one of 352 subjects were unable to perform at least one activity. These subjects demonstrated higher AQ20-R scores (p < 0.001) indicating worse HRQL. Mean (+/- SD) AQ20-R scores differed significantly (p < 0.001) among subjects with COPD (8.9 +/- 5.2), asthma (6.7 +/- 5.0), and chronic bronchitis (4.7 +/- 4.2). At baseline, the AQ20-R correlated with the SF-12 PCS (r = - 0.55, p < 0.001) and FEV(1) (r = - 0.43, p < 0.001), and was associated with the use of respiratory-specific therapies (p

Purpose: To evaluate the ability of the Seattle Obstructive Lung Disease Questionnaire (SOLDQ) to detect change in health-related quality of life (HRQOL) following a pulmonary rehabilitation program (PRP) and to determine associations with other functional indicators., Methods: A prospective pre- and post-test design. A PRP was offered for 60 minutes, 2 times per week for 8 weeks. Measured at entry and exit to the PRP: the SOLDQ (physical, emotional, and coping skills), 6-minute walk, Medical Outcomes Study Short Form Health Survey-36 Veterans (SF-36V) (physical and mental), Lareau Functional Status and Dyspnea Questionnaire, and the Multidimensional Assessment of Fatigue (MAF) scale. Setting was an outpatient PRP in a VA Medical Center., Results: Participants included 58 adults who completed the PRP (age mean = 66, SD +/- 9.8; FEV1% predicted mean = 39, SD +/- 15.9). At baseline, significant correlations were found between SOLDQ physical functioning and SF-36V physical, dyspnea, fatigue, 6-minute walk distance, SF-36V mental, and spirometry. SOLDQ emotional functioning significantly correlated with fatigue, dyspnea, and SF-36V mental and physical. SOLDQ coping skills significantly correlated with fatigue, dyspnea, and SF-36V mental and physical. Paired, 2-tailed, t tests comparing the SOLDQ subscales pre- and post-program were significant, with the biggest treatment effect seen with emotional functioning. Other measures showing significant improvement included 6-minute walk, SF-36V physical, dyspnea, and fatigue., Conclusions: After participation in a PRP, all 3 SOLDQ subscales improved significantly and were associated with other indicators of function. These findings validate the SOLDQ as a measure sensitive to functional changes associated with participation in pulmonary rehabilitation.

Traditionally, quality-of-life researchers describe states of health for patients to rate either in narrative form or in table form, but evidence about which format patients prefer is limited. The authors performed 2 randomized studies to test whether patients prefer the table or narrative format and whether the format of presentation influences how patients rate health states. Approximately three-fourths of patients with gastrointestinal disease or chronic airflow limitation preferred the table format. There were no differences in patients' ratings of 3 described health states or of their own health. Investigators should consider using the table presentation for describing health states to subjects who are not familiar with these states of health.

The perception of dyspnoea differs between subjects with obstructive pulmonary diseases, partly because the underlying mechanisms for bronchoconstriction are different. We investigated the perception of bronchoconstriction in subjects with bronchiectasis, asthma and chronic bronchitis and possible contributing factors. Forty-seven non-smoking subjects with bronchiectasis, 50 subjects with asthma and 31 with chronic bronchitis were challenged with histamine. The Borg score was assessed before and after each challenge. The perception score corresponding to a fall in the forced expiratory volume in 1 s (FEV(1)) by 20% (PS(20)) was calculated. The mean values of DeltaBorg/DeltaFEV(1) (the Borg score change divided by the change in FEV(1) as a percentage of the baseline FEV(1)) and PS(20) of subjects with bronchiectasis and chronic bronchitis were significantly lower than in subjects with asthma after histamine challenge. The ratio of non-perceivers was higher in bronchiectasis (25.5%) and in chronic bronchitis (32.3%) than in asthma (4.0%). When all subjects were considered, DeltaBorg/DeltaFEV(1) values were significantly related to female sex ( r (2)=11.5%, P =0.0001), but not to age, duration of the disease, PD(20) or baseline FEV(1)%. The present study indicates that perception of histamine-induced bronchoconstriction is lower in patients with bronchiectasis and chronic bronchitis than in asthmatic patients, and that sex partially contributes to this difference.

Introduction: Dyspnoea, defined as the perception of difficult or laboured breathing, is ideally quantified, using a visual analogue scale or a Borg scale., State of the Art: In recent years several studies have explored the correlation between dyspnoea and the degree of airway obstruction, in both healthy subjects and patients with asthma or COPD. In these studies dyspnoea was measured in baseline state, following induced broncho-constriction or during application of an external resistive load. Dyspnoea was measured using a previously validated scale or, in some studies, a simple numerical score. The lung function variables most frequently used to evaluate the degree of correlation with dyspnoea were FEV1, and PEF, although other variables were used in some studies. Despite this marked heterogeneity in the methods used, several studies strongly suggested that, in subjects with COPD, perceived subjective improvement after an inhaled bronchodilator agent correlated with improvement of inspiratory variables. In asthmatics, the major finding was that some subjects had a very poor perception of their level of airway obstruction, a potential risk factor for severe exacerbations., Perspectives: Further normative studies are needed to define how healthy subjects perceive airway obstruction., Conclusions: The relationship between dyspnoea and lung function in obstructive disorders has to be evaluated separately in asthmatics and in COPD patients.

Twenty-nine patients with severe chronic obstructive pulmonary disease (COPD) on long-term oxygen therapy (LTOT) were prospectively studied for compliance with therapy. Seven patients (24%) used oxygen < 16 hours/day and their mean 24-hour pulse oximetry showed mild hypoxaemia. In addition, we found that eight patients (28%) were smokers. We suggest that the follow-up of these patients should focus on the daily duration of the use of oxygen and cessation of smoking to optimise the effect of this therapy.

Methods for measuring health-related quality of life have been developed and proven valid during the past two decades. It was accomplished through international collaborations between clinicians and method experts. Standardized questionnaires, self-administered by patients, include key domains such as symptoms, functional limitations and well-being from a physical, mental and social perspective. The commonly used instruments are adapted and validated for Swedish conditions. Clinical trials can be powered also according to these outcome measures, as they show documented responsiveness to important changes in patients' everyday functioning and well-being. Patient-reported outcome of treatment efficacy is nowadays adequately standardized for scientific reviews according to the conventional criteria of evidence based medicine. Most importantly, health-related quality of life measures will provide new information of clinical value as demonstrated here in the example of asthma/chronic obstructive pulmonary disease. Thus, outcome can be better assessed by changes in the total burden of disease and its consequences than in terms of pulmonary function tests or biochemical markers.

Only a small percentage of smokers who state they want to stop smoking in the next half year, succeed in doing so. This is not only due to the addictive nature of smoking cigarettes, but also because of psychological and social factors. Approximately 80% of the people who have used nicotine-replacement therapy return to smoking after some time. Therefore, the interest in non-nicotine pharmacotherapy has increased considerably in recent years. The antidepressants bupropion and nortriptyline are, compared to a placebo, particularly effective smoking cessation aids (relative risk (RR)nortriptyline: 2.7; 95% CI: 1.3-5.3; RRbupropion: 1.5; 95% CI: 1.1-2.6). A combined strategy of nicotine-replacement therapy with counselling or antidepressants (bupropion or nortriptyline) with counselling, in which the physiological as well as the psychological aspects of smoking cessation are treated, seems to be the most effective. Although smoking cessation is seen as the single most important way of preventing a further deterioration of the lung function at all stages of chronic obstructive pulmonary disease (COPD), little research has been conducted amongst COPD patients. Especially the use of the antidepressants bupropion or nortriptyline seems particularly interesting for the treatment of patients with COPD. This is not only because smoking cigarettes is the major risk factor for the development of the disease, but also because COPD patients have a higher than normal prevalence of depression. Furthermore, an association has been found between smoking cigarettes and depression, and the presence of depression or depressive symptoms appears to be an important cause of relapse.

The provision of domiciliary oxygen to patients hypoxic at hospital discharge has been termed short-term oxygen therapy (STOT). This practice appears widespread, although there is a paucity of literature and no evidence-based guidelines. We undertook this audit to examine the prescription of STOT and determine the proportion fulfilling for long-term oxygen therapy (LTOT) 2 months post-discharge. STOT was defined prospectively: resting PaO2 < or = 7.3 kPa (55 mmHg) or PaO2 between 7.3 and 8.0 kPa (60 mmHg) with any of the following: clinical evidence of cor pulmonale (pedal oedema or jugular venous distension), ECG evidence of pulmonale, echocardiogram evidence of pulmonary hypertension, haematocrit > 0.55 (adapted directly from LTOT criteria). Patients were evaluated for LTOT 2 months post-discharge when clinically stable on optimal medical management. All referrals to the Auckland Regional Oxygen Service between July 1998 and 1999 were systematically reviewed. The majority 289/405 (71%) of new referrals were for the prescription of STOT/LTOT in patients with chronic lung disease: 160/289 (55%) derived from hospitalized patients with the majority 130 (81%) fulfilling criteria for STOT, median age 73, range 24-96 years. Mean hospital stay was 10.2 days. Two months after discharge 22/127 (17%) of STOT patients had died, comparable with 4/22 (18%) not fulfilling criteria for STOT. A total of 123 patients were assessed for LTOT at 2 months; 76 (62%) fulfilled criteria for LTOT. The prescription of oxygen at hospital discharge represented a considerable proportion of our referral load. There was a high mortality in the 2-month follow-up period. A significant proportion of STOT patients did not subsequently fulfill criteria for LTOT. Further prospective studies are required in order to develop evidence-based guidelines.

Background: Physical activity is a key dimension of functional status in people with chronic obstructive pulmonary disease (COPD), and the central target of interventions in this group., Objectives: To determine the relationships among functional performance measured as physical activity, functional capacity, symptom experiences, and health-related quality of life in people with COPD., Method: Cross-sectional, descriptive study. Convenience sample of 63 outpatients with COPD studied prior to entry into a pulmonary rehabilitation program., Results: Daily physical activity, as measured by an accelerometer, was strongly associated with maximal distance walked during a 6-minute walk test (r = .60, p < .00), level of airway obstruction (r = .37, p < .01), walking self-efficacy (r = .27, p < .05), and physical health status (r = .40, p < .01). Physical activity was not correlated with self-report of functional status. The only predictor of physical activity was the 6-minute walk test., Conclusions: Accelerometer measurement of functional performance was most significantly related to walking abilities. This methodology represents a novel approach to measuring an important dimension of functional status not previously well quantified.

Introduction: The conclusion of previous investigations that pulmonary rehabilitation (PR) is an effective intervention for the management of chronic lung disease may not be generalizable to PR programs with limited experience delivering this complex, interdisciplinary service., Objective: Determine whether PR is effective for the first group of patients treated in a newly formed interdisciplinary PR program., Methods: We conducted a longitudinal analysis of changes in health-related quality of life and 6-minute walk test for the first group of patients completing our newly formed 8-week outpatient PR program. We studied 6 men, age 65-77 years, with stable severe chronic obstructive pulmonary disease. Patients completed the Chronic Respiratory Disease Questionnaire immediately before and 1 year after participation in our PR program., Results: Four patients completed the PR 6-minute walk test both before and after the program. We found improvement in all Chronic Respiratory Disease Questionnaire domains at follow-up (mean +/- SD before and after): dyspnea 1.67 +/- 0.82 vs 4.92 +/- 0.49; emotional function 2.33 +/- 0.82 vs 5.50 +/- 0.55; fatigue 2.00 +/- 0.63 vs 5.00 +/- 0.63; feeling of mastery over disease 1.83 +/- 0.41 vs 5.83 +/- 1.17. The interval improvements in all health-related quality of life domains were statistically significant (p < 0.02 for all comparisons). There was a trend toward improvement in exercise tolerance: 231 +/- 213 ft before PR vs 353 +/- 66 ft at the 1-year follow-up (p = 0.2)., Conclusions: PR can result in sustained improvement in the quality of life of patients with severe chronic obstructive pulmonary disease, even when this complex, interdisciplinary service is delivered by a newly formed and inexperienced PR program.

A number of studies in western countries have shown that respiratory and physical rehabilitation of patients with chronic obstructive pulmonary disease (COPD) only has a minimal effect on respiratory function but can significantly improve physical capacity. The aim of our study was to apply these methods to patients in Kinshasa, Democratic Republic of Congo. We treated 38 patients (20 women) who had bronchial asthma (n=14) or COPD (n=24). These ambulatory patients were treated in two different hospitals in Kinshasa, the university hospital and the general hospital, three times per week for twelve weeks. The patients were treated with kinestherapy and inhaled bronchodilator drugs (salbutamol, and/or ipratropium bromide with a boreal nebulizer) as well as bronchial hygiene and performed breathing exercises on a Bodyguard Ergometer 990 with walking, running and climbing steps until exhaustion. After the rehabilitation program FEV1 increased from 1.37 +/- 0.62 (50% expected) to 1.54 +/- 0.69 (56% expected) (p<0.01). The same trend was observed for walking distance (from 644 +/- 459 m to 1213 +/- 569 m, p<0.001) and for maximal power developed on the cycloergometer (from 45 +/- 20 w to 73 +/- 37 w, p<0.001). In contrast, the maximal work load performed during climbing steps (from 106 +/- 44 w to 115 +/- 23 w) did not improve significantly. COPD patients improved their FEV1 significantly compared with asthma patients. Our study show that pulmonary rehabilitaion increase the level of spontaneous physical activity. The pulmonary rehabilitation program changes the quality of life of COPD patients who are able to move about better for longer periods of time, have a longer walking distance, and improved physical activity level.

The extent to which a chronic obstructive pulmonary disease (COPD) patient is impaired in health-related quality of life (HRQoL) is only to a small extent reflected in clinical and demographical measures. As the influence of comorbidity on HRQoL is less clear, we investigated the added value of 23 common diseases in predicting HRQoL in COPD patients with mild to severe airways obstruction. COPD patients from general practice who appeared to have an forced expiratory volume in 1 sec/inspiratory vital capacity (FEV1/IVC) < predicted -1.64 SD, FEV1 <80% predicted, FEV1 reversibility < 12% and a smoking history, were included (n=163). HRQoL was assessed with the short-form-36 (SF-36) and the presence of comorbidity was determined by a questionnaire, which asked for 23 common diseases. All domains of the SF-36 were best predicted by the presence of three or more co-morbid diseases. FEV1 % predicted, dyspnoea and the presence of one or two diseases were second-best predictors. Co-morbidity explained an additional part of the variance in HRQoL, particularly for emotional functioning (delta R2=0.11). When individual diseases were investigated, only insomnia appeared to be related to HRQoL. As HRQoL is still only partly explained, co-morbidity and other patient characteristics do not clearly distinguish between COPD patients with severe impairments in HRQoL and COPD patients with minor or no impairments in HRQoL. Therefore, it remains important to ask for problems in daily functioning and well-being, rather than to rely on patient characteristics alone.

Objectives: To examine the acceptability of fluoxetine in elderly depressed patients with chronic obstructive pulmonary disease (COPD)., Setting: A university teaching hospital., Method: Single-blinded (open) study. One hundred and thirty-seven outpatients (69 male) with symptomatic irreversible, moderate to severe COPD were recruited. Major depression was diagnosed using the Geriatric Mental State Schedule. Quality of life was assessed by the Breathing Problems Questionnaire, physical disability by the Manchester Respiratory Activities of Daily Living Questionnaire and severity of depression using the Montgomery Asberg Depression Rating Scale. Exclusion criteria were: use of oral steroids within 6 weeks, acute or chronic confusion, known cancer and known psychosis., Results: Fifty-seven patients (42%) (25 males) with a mean age of 72 years (range 60-89 years) were depressed. Fourteen (six male) agreed to undergo therapy with fluoxetine 20 mg/day for 6 months, while 36 (72%) refused antidepressant drug therapy. Only seven subjects completed the trial; of these, four (57%) responded to fluoxetine therapy. Five subjects withdrew because of side-effects. Twenty-two of those who refused treatment (61%) agreed to be interviewed, and of these 19 (86%) were still depressed., Conclusion: Patient acceptance of fluoxetine was poor. The reasons for refusing treatment varied but were largely due to misapprehension by the patient. Untreated depression became chronic. Offering antidepressants to COPD patients with depression is not an effective strategy. Why this might be so is discussed., (Copyright 2001 John Wiley & Sons, Ltd)

Objective: To ascertain the differences in smoking characteristics between a group of smokers with COPD and another group of healthy smokers, both of which were identified in a population-based epidemiologic study., Design and Participants: This is an epidemiologic, multicenter, population-based study conducted in seven areas of SPAIN: A total of 4,035 individuals, men and women aged 40 to 69 years, who were selected randomly from a target population of 236,412 subjects, participated in the study., Interventions: Eligible subjects answered the European Commission for Steel and Coal questionnaire. Spirometry was performed followed by a bronchodilator test when bronchial obstruction was present. The Fagerström questionnaire was used for study of the degree of physical nicotine dependence, and the Prochazka model was followed for analysis of the smoking cessation phase., Results: Of 1,023 active smokers, 153 (15%) met the criteria for COPD. Smokers with COPD were more frequently men (odds ratio [OR], 2.18; 95% confidence interval [CI], 1.21 to 3.95), were > or = 46 years of age (OR, 1.97; 95% CI, 1.18 to 3.31), had a lower educational level (OR, 1.96; 95% CI, 1.23 to 3.14), and had smoked > 30 pack-years (OR, 3.70; 95% CI, 2.42 to 5.65). Smokers with COPD showed a higher dependence on nicotine than healthy smokers (mean [+/- SD] Fagerström test score, 4.77 +/- 2.45 vs 3.15 +/- 2.38, respectively; p < 0.001) and higher concentrations of CO in exhaled air (mean concentration, 19.7 +/- 16.3 vs 15.4 +/- 12.1 ppm, respectively; p < 0.0001). Thirty-four percent of smokers with COPD and 38.5% of smokers without COPD had never tried to stop smoking., Conclusions: Smokers with COPD have higher tobacco consumption, higher dependence on nicotine, and higher concentrations of CO in exhaled air, suggesting a different pattern of cigarette smoking. Cases of COPD among smokers predominate in men and in individuals with lower educational levels. A significant proportion of smokers have never tried to stop smoking; thus, advice on cessation should be reinforced in both groups of smokers.

The underlying premise of narrative research within social science literature is the belief that individuals most effectively make sense of their world by (re)constructing stories. Chronic Obstructive Pulmonary Disease (COPD) is a progressive degenerative respiratory disorder that affects approximately 15% of Canadians annually. Prior to the study discussed in this article, no research had been done to understand the frightening event of an acute exacerbation episode of COPD from the perspective of patients and their family caregivers. Hence, 10 family-nurse units were interviewed during an acute exacerbation event. The participants told a number of near-death and shadow-of-death stories that describe these episodes as life changing and illustrate the centrality of these events in the participants' understanding of their chronic illness.

Background: We hypothesized that compared to an educational intervention, a single 2 h session of cognitive behavioural therapy (CBT), with 6-week follow-up, would reduce anxiety and depression, improve physical and mental functioning, and lead to a better quality of life and greater satisfaction with treatment in older patients with chronic obstructive pulmonary disease (COPD)., Methods: Fifty-six subjects were recruited from a large, urban, academically affiliated Veterans Affairs (VA) Hospital, a non-profit private hospital, and a local newspaper, for a single blind randomized controlled clinical trial. One 2 h session of group CBT was designed to reduce symptoms of anxiety, with specific components including relaxation training, cognitive interventions, and graduated practice, followed by homework and weekly calls for 6 weeks. This was compared to a group that received 2 h of COPD education, followed by weekly calls. Pre- and post-intervention subjects in both groups were administered SF-36, Geriatric Depression Scale, Beck Anxiety Inventory, 6 min walk test, and the FEV-1. Following the intervention, both groups completed the Client Satisfaction Questionnaire., Results: When compared with a group that received education about COPD, 2 h CBT group showed decreased depression and anxiety. Contrary to our hypothesis, despite the decrease in depression and anxiety, there was no change in the physical functioning of the patients., Conclusions: Twenty to 40% of patients with COPD have high levels of anxiety and depression. Our study finds that as little as 2 h of CBT administered in a group setting is able to reduce these anxious and depressive symptoms.

Objective: The goal of this study was to explore specific psychiatric morbidity among chronic obstructive pulmonary disease (COPD) patients in Nigeria., Method: The mental status of 30 COPD patients was compared with those of 30 uncomplicated hypertensive patients and 30 apparently healthy controls using the 30-item General Health Questionnaire (GHQ-30) and Present State Examination (PSE). The sociodemographic characteristics of the three groups were also compared., Results: The COPD population was significantly least educated and predominantly subsistent farmers. Thirty percent of the COPD population, 13.3% of the hypertensive patients and 3.3% of apparently healthy controls had psychiatric morbidity (P<.05). The COPD population, with psychiatric diagnoses consisted of 16.7% depressive episode, 10% generalized anxiety disorder and 3.3% delirium. This pattern is similar to data from industrialized countries. No sociodemographic factors were significantly associated with psychiatric morbidity., Conclusion: Improving the psychiatric knowledge of the primary physician will result in better management of the COPD patient.

Background: The aim of our survey was to record the experiences of hospitalised patients with respiratory diseases in order to create a more patient-friendly department., Material and Methods: Our study included 609 patients (response rate 70%) with a median age of 64 years (range 13-91) who were discharged from the Department of Thoracic Medicine, Haukeland University Hospital in October 1991, 1992, 1994, 1995 and 1996. 268 patients had obstructive lung disease, 82 had lung cancer. They answered a questionnaire with 24 questions., Results: Patient reception to the ward and staff knowledge of the patients' illnesses, were for the physicians rated as good or better by 92% and 79% and for the nurses by 94% and 70% respectively. 16% of the patients experienced insecurity, 17% anxiety, 12% helplessness, 9% loneliness and 12% little say in the decision making process. Trend factors for these emotional experiences were female sex, old age, obstructive lung disease and long stay in hospital. Patients aged 50 to 69 years and patients with lung cancer had the lowest rate of negative emotional experiences. Despite staff awareness of the prevalence and of the patients' emotional experiences and the risk factors involved, there was no clear reduction of negative experiences in the later surveys compared to the first survey., Interpretation: Patients in a university hospital with respiratory diseases showed unchanged experiences of health care and personal emotions in repeated surveys over a period of five years.

This study evaluated the association between depressive symptoms and health related quality of life (HRQoL) in patients with chronic pulmonary disease using both general and disease-specific HRQoL measures. A cross-sectional analysis of HRQoL measures completed by patients enrolled in the Department of Veteran Affairs Ambulatory Care Quality Improvement Project. 1252 patients with chronic pulmonary disease screened positive for emotional distress and returned the Hopkins Symptom Checklist-20 (SCL-20). 733 of 1252 had a score of 1.75 or greater on the SCL-20 indicating significant depressive symptoms. Depressive symptoms were associated with statistically significantly worse general and pulmonary health as reflected by lower scores on all sub-scales of both the Medical Outcomes Short Form-36 and the Seattle Obstructive Lung Disease Questionnaire. In fact, 11% to 18% of the variance in physical function sub-scales was attributed to depressive symptoms alone. Patients with chronic pulmonary disease and depressive symptoms reported significantly more impaired functioning and worse health status when compared to those patients without depressive symptoms. Because there are highly effective treatments for depression, selective screening of patients with chronic pulmonary disease for depression may identify a group that could potentially benefit from treatment interventions.

Our aim was to study anxiety and/or depression comorbidity and the influence of these comorbid conditions on disability for 3 clinical groups of pulmonary tuberculosis and chronic obstructive pulmonary disease (COPD). We also investigated the applicability of General Health Questionnaire 12 (GHQ12) for these clinical groups as a simple screening test for psychiatric comorbidity. A total of 157 male inpatients were included in the study: 42 with recently diagnosed (RDtb), 39 with defaulted (Dtb), 39 with multidrug resistant tuberculosis (MDRtb) and 38 with COPD. The presence of depression and anxiety was assessed by Composite International Diagnostic Interview (CIDI). Disability was evaluated by Brief Disability Questionnaire. The validity of GHQ12 for the study groups was examined in order to determine a functional cut-off point. Depression and/or anxiety comorbidity was 19% for RDtb, 21.6% for Dtb, 25.6% for MDRtb and 47.3% for COPD. Patients with psychiatric comorbidity had higher disability scores than the group without psychiatric comorbidity. For the tuberculosis group a 3/4 cut-off point of GHQ had 80.7% sensitivity and 87.1% specificity while a 5/6 cut-off point with 83.3% sensitivity and 80% specificity was applicable to the COPD group.

Purpose: To measure the prevalence rate of significant depressive symptoms and depression and examine their consequences on quality of life in patients with severe oxygen-dependent chronic obstructive pulmonary disease (COPD)., Methods: Between November 1997 and March 1998, the authors conducted a cross-sectional study among the COPD patients registered at the Quebec City area respiratory home care service. Depression and quality of life were assessed using the Geriatric Depression Scale and the Medical Outcome Survey--Short Form 36 (SF-36)., Results: 109 patients (63 men; mean age: 71) with severe COPD (median FEV1: 34%) were surveyed. Of them, 105 were on long-term oxygen therapy (LTOT), which had been introduced (median) 19 months earlier. Sixty-two patients (57%; 95% Cl: 47-66) demonstrated significant depressive symptoms; in addition, 20 patients (18%; Cl: 12-27) were severely depressed. Only 6% of those patients who met the criteria for depression were taking an antidepressant drug. We found significant and moderate correlations between the scores obtained from the Geriatric Depression Scale and 7 of the 8 domains of the SF-36., Conclusion: Significant depressive symptoms and depression are highly prevalent in patients with severe COPD on LTOT. There is strong evidence that depression is under-recognized and under-treated in this group of patients.

A sample of 37 patients with severe chronic obstructive pulmonary disease (COPD) drawn from a larger group of 64 patients being studied in a randomized trial of nebulizer versus high-dose inhaler therapy, and similar in age and gender mix, was interviewed in depth, with a view to illuminating standardized outcome measures and improving the understanding of these patients' needs. Three patients are described in detail. The interview material was analysed using non-computerized methods. Quality of life was seen as depending mainly on family relationships, opportunities afforded locally for neighbourliness and freedom from fear, mobility and independence in the activities of daily living, and the absence or successful mitigation of symptoms of concomitant disease. Disease-specific, symptom-oriented outcome measures may miss these. Additionally, the near and repeatedly threatening approach of death recommended extension of a palliative approach to endstage COPD.

Health related quality of life (HRQOL) is an important criterion for the evaluation of rehabilitation measures in patients with chronic obstructive pulmonary disease (COPD). The present paper reviews the current literature about the effects of pulmonary rehabilitation on the HRQOL of patients with COPD. The aim is to summarize critically methods, results and unanswered issues of the present research on the effects of pulmonary rehabilitation on HRQOL. The rehabilitation of patients suffering of COPD is mainly based on six types of interventions: 1. long-term oxygen therapy (LTO), 2. pharmacological management, 3. surgical therapy (bilateral reduction of lung volume), 4. physical therapy, 5. nutritional therapy (special diets), and 6. psycho-social interventions (e.g. psychotherapy, training and education). Thirty-one studies could be included in which HRQOL served as an outcome criterion for the rehabilitation of COPD patients. In 14 (45%) studies exclusively a disease-specific measure for the assessment of HRQOL was employed, while in 12 (39%) studies a generic instrument was applied. In the remaining five (16%) studies two ore more measures were used, whereas four of them combined a generic and a disease-specific method. The St. Georges Respiratory Questionnaire (SGRQ) und the Chronic Respiratory Disease Questionnaire (CRDQ) belonged to the group of the specific instruments, while among the generic measures the Sickness Impact Profile (SIP), the Nottingham Health Profile (NHP), the SF-36 and the Quality of Well-Being Scale (QWB) were most frequently used in COPD patients. The surgical bilateral reduction of lung volume, pharmacological therapy, upper extremities muscle training and psychological measures as single interventions proved to have persistent positive effects on the HRQOL. Several rehabilitation programs, composed of a wide variety of different interventions were effective in terms of HRQOL. On the other hand, at follow-up, the short-term positive effects had decreased in two of the three studies, where the rehabilitation took place exclusively in an inpatient setting. However, in three of four programs implemented in an outpatient setting, a persistent positive effect on HRQOL could be demonstrated. In conclusion from the as of yet available findings, we suggest for future studies to use only such measures of HRQOL which have been tested psychometrically in patients with COPD and to combine disease-specific and generic measures. In order to achieve lasting positive effects of rehabilitation on HRQOL, outpatient settings or ambulatory refreshment sessions following rehabilitation on an inpatient basis should be preferred.

What psychosocial issues do adolescent cystic fibrosis (CF) patients experience after undergoing lung transplantation (Tx)? The aim of this study was to determine, using an ethnographic study design, the common themes and emotional responses in post-lung transplant adolescent CF patients of the Cardiothoracic Transplant Clinic at the Childrens Hospital Los Angeles. Nineteen CF lung transplant recipients were studied (eight males, 11 females: mean age at time of transplant, 15.7 +/- 2.7 yr). The mean time interval from Tx to interview was 25.4 months (range 1-58 months). Sixteen patients had living donor lobar lung Tx while three patients received cadaveric lungs. A series of 25 questions was used to assess the psychosocial impact of Tx, and a semi-structured interview focused on the following five domains: lifestyle, family functioning, social functioning, body image, and psychological functioning. The major themes identified by patients included: a strong desire to set and attain meaningful long-range goals, the need to control as many aspects of their lives as possible while dealing with parental over-protectiveness, and the adjustment to a new lifestyle. Common emotional responses included manageable fear/anxiety of lung rejection and uncertainty of the future, impatience with disruptions of daily routines caused by post-transplant medical management and its effect on the attainment of set goals, and frustration with parental over-protectiveness. In general, patients reported a positive outlook on life, with greater emphasis on sought-after goals as well as inter-personal relationships. This study demonstrates that adolescent CF transplant recipients develop long-term goals and plans for independence. By identifying and anticipating the emotional needs of this population, health care providers can assist patients in improving the quality of their lives from a physiological, as well as a psychological, viewpoint.

Our study objective was to identify factors predicting length of hospital stay of older patients with exacerbated chronic obstructive pulmonary disease (COPD) through a multicenter, cross-sectional, retrospective study. We examined 3789 patients aged 74.3+/-11.1 years (mean+/-SD), 66.1% males, consecutively hospitalized in 32 wards of General Medicine and 31 of Geriatrics in acute care hospitals for exacerbated COPD in 10 bimonthly periods between 1988 and 1997. On admission, patients underwent a structured assessment of demographic data, nutritional status, cognitive and physical functions, comorbidity, and pharmacological therapy in the two weeks prior to admission. Patients were grouped according to whether their length of stay exceeded or not the 75th percentile of stay distribution in each bimonthly period. Variables univariately distinguishing groups were entered into a logistic regression analysis having long-stay as the dependent variable. Living alone (Odds Ratio 1.33, 95% Confidence Limits 1.03-1.70), use of more than 3 drugs prior to admission (OR 1.29, CL 1.09-1.51), use of drugs with respiratory depressant properties prior to admission (OR 1.24, CL 1.05-1.46), and the presence of more than 3 comorbid diseases (OR 1.88, CL 1.61-2.19) were independent correlates of long-stay. Age did not predict length of stay. In conclusion, selected health outcomes and indicators of disease severity, but not age, target COPD patients at risk of long-stay. Research is needed to verify whether these data can help program interventions aimed at shortening length of stay and, thus, at reducing annual hospitalization costs of the elderly.

Study Objectives: The purpose of this study was to evaluate the effects of a 3-week comprehensive pulmonary rehabilitation program on quality of life as measured by the Short Form-36 (SF-36) in patients with COPD., Design and Setting: We report on the outcomes of 37 consecutive patients referred for pulmonary rehabilitation at a respiratory specialty medical center., Patients: Thirty-seven patients (mean age, 66 years) with COPD and severe airflow limitation (mean +/- SE FEV(1), 29.6 +/- 1.8% of predicted) were studied., Interventions: Rehabilitation consisted of a 3-week pulmonary rehabilitation program incorporating 12 exercise sessions, each of which included bicycle ergometer exercise training, upper-extremity training, strength training, and stretching, along with psychosocial counseling and education., Measurements and Results: The Health Status Index (SF-36) and 6-min walk test were completed before and after rehabilitation. There was an improvement in five of the nine quality-of-life subscales of the SF-36 following pulmonary rehabilitation. Although there was an improvement in functional capacity as measured by the 6-min walk, there was no correlation between improvement in quality of life and improvement in functional capacity. There was no correlation between FEV(1) and improvement in walk distance, but there was a correlation between FEV(1) and improvement in SF-36 physical function and energy/fatigue subscales., Conclusion: Health-related quality of life assessed by the SF-36, a general measure of quality of life, improves following an intensive 3-week pulmonary rehabilitation program. Use of the SF-36 allows comparison of the results of pulmonary rehabilitation to therapeutic interventions in patients with other medical disorders.

This paper reports a case of a 71-year-old pulmonary emphysema patient with neuropsychological impairments that were markedly improved 6 months after he underwent lung volume reduction surgery (LVRS). He also underwent pulmonary rehabilitation before and after surgery. He was suspected of having memory impairment and attention disorder when he was referred for rehabilitation. The neuropsychologic test showed a general cognitive impairment, attention disorder, and verbal memory impairment. Magnetic resonance imaging showed moderate atrophy of the left hippocampal area, cortex, and lacunae infarction in the periventricular area. Interestingly, scores of the neuropsychologic test, as well as severity of dyspnea and lung function, remarkably improved 6 months after LVRS. These results suggested that the neuropsychological impairments in pulmonary emphysema patients can be improved after lung reduction surgery.

Introduction: The purpose of this prospective study is to determine the effects of a pulmonary rehabilitation programme (PRP) conducted at our centre for patients with chronic lung disease., Materials and Methods: Thirty-four patients (27 men and 7 women, mean age 67.7 years) with predominantly moderate-to-severe chronic obstructive pulmonary disease (31 patients), bronchiectasis (2 patients) and interstitial lung disease (1 patient) completed a 6-week outpatient PRP that included education, physical and respiratory care instruction and supervised exercise training. Outcome assessment was performed at baseline, on completion of PRP and 3 months after PRP. Physiologic measures included pulmonary function, incremental exercise and 6-minute walk tests (6MWTs). Disease-specific quality of life was assessed using the Chronic Respiratory Disease Questionnaire (CRDQ)., Results: There was no significant change in resting spirometry or lung volumes after PRP. Maximal oxygen uptake and work-rate improved significantly after PRP by 132.4 mL kg-1 min-1 and 10.7 W, respectively. 6MWT distance improved significantly by a mean of 67.3 m (P < 0.0001). Maximum Borg dyspnoea scores decreased significantly by 1.2 +/- 0.5 (P < 0.038). All domains of the CRDQ completed by a sub-group of patients improved significantly and the total scores increased by a mean of 21.7 points at the end of the PRP. The improvements gained in maximal exercise capacity immediately following PRP were maintained in 17 patients who returned for repeat assessment 3 months after PRP., Conclusion: Patients who completed a comprehensive PRP at our centre showed significant increase in functional capacity, reduction of exertional dyspnoea and improvement in health status.

Objectives: Depressive and anxiety symptoms are common in elderly patients with chronic obstructive pulmonary disease (COPD). However, true prevalence of clinical depression and anxiety is uncertain. We thus aimed to assess prevalence of clinical depression and/or anxiety in elderly COPD patients using the Geriatric Mental State Schedule (GMS) and determine severity of clinical depression by the Montgomery Asberg Depression Rating Scale (MADRS). We also aimed to validate the Brief Assessment Schedule Depression Cards (BASDEC) screening test for depressive symptoms against GMS., Setting: A university teaching hospital., Participants: Subjects comprised 137 (69 men) outpatients with COPD, aged 60 - 89 (mean 73) years. Exclusion criteria were acute respiratory exacerbation or use of oral corticosteroid within 6 weeks, known psychosis, acute or chronic confusion., Measurements: A GMS score > or =3 is diagnostic of clinical depression, and a BASDEC score > or =7 is classed as "case". GMS was taken as gold standard. Severity of depression was assessed by the MADRS:, Results: Mean (SD) one second forced expiratory volume was 0.89 (0.3) litres. Sixty-two subjects (46%) scored as a "case" on BASDEC and 57 subjects (42%) were identified as clinically depressed on GMS. In the depressed the prevalence of anxiety was 37% and in the non-depressed 5%. BASDEC performed well against GMS, having a sensitivity of 100%; a specificity of 93%; a positive predictive value of 91% and a negative predictive value of 100%. Assessment of severity of depression by MADRS showed that 17 subjects (30%) were mildly depressed, 39 (68%) were moderately depressed and one (2%) was severely depressed., Conclusion: Clinical depression and anxiety are common in elderly patients with COPD, though clinical anxiety seems mainly confined to those who also suffer clinical depression. Of those depressed, two-thirds scored in the moderately depressed range. BASDEC is a valid screening tool in this patient group., (Copyright 2000 John Wiley & Sons, Ltd.)

Background: Patients with severe chronic obstructive pulmonary disease (COPD) have a poor quality of life and limited life expectancy. This study examined whether these patients were relatively disadvantaged in terms of medical and social care compared with a group with inoperable lung cancer., Methods: An open two group comparison was made of 50 patients with severe COPD (forced expiratory volume in one second (FEV(1)) <0.75 l and at least one admission for hypercapnic respiratory failure) and 50 patients with unresectable non-small cell lung cancer (NSCLC). A multi-method design was used involving standardised quality of life tools, semi-structured interviews, and review of documentation., Results: The patients with COPD had significantly worse activities of daily living and physical, social, and emotional functioning than the patients with NSCLC (p<0.05). The Hospital Anxiety and Depression Scale (HADS) scores suggested that 90% of patients with COPD suffered clinically relevant anxiety or depression compared with 52% of patients with NSCLC. Patients were generally satisfied with the medical care received, but only 4% in each group were formally assessed or treated for mental health problems. With regard to social support, the main difference between the groups was that, while 30% of patients with NSCLC received help from specialist palliative care services, none of the patients with COPD had access to a similar system of specialist care. Finally, patients in both groups reported a lack of information from professionals regarding diagnosis, prognosis and social support, although patients' information needs were disparate and often conflicting., Conclusion: This study suggests that patients with end stage COPD have significantly impaired quality of life and emotional well being which may not be as well met as those of patients with lung cancer, nor do they receive holistic care appropriate to their needs.
