COVID-19 and collective trauma: Implementing a trauma-informed model of care for post-COVID patients.

AIM: To describe the implementation of a trauma-informed model of care in the Post COVID Respiratory Clinic of a large tertiary referral centre in NSW. DESIGN: Discussion paper. DATA SOURCES: Evidence gathered from a literature search (2008-2022) was used to develop a framework for management of patients presenting to this Post COVID Respiratory Clinic. This paper outlines the personal reflections of the clinic staff as they developed and implemented this framework. Ethical approval was obtained to report the data collected from patient reviews. DISCUSSION: The literature highlights the high prevalence of trauma in patients following COVID-19 infection, as well as the larger population both during and after the pandemic. This experience of trauma was observed in patients seen within the clinic, indicating a need for specialized care. In response, a trauma-informed model of care was implemented. CONCLUSION: Reconceptualizing COVID-19 as a 'collective trauma' can help healthcare workers understand the needs of post-COVID patients and enable them to respond empathetically. A trauma-informed model is complementary to this cohort as it specifically addresses vulnerable populations, many of whom have been further marginalized by the pandemic. IMPLICATIONS FOR NURSING AND PATIENT CARE: Frontline healthcare workers, particularly nurses, are well positioned to implement trauma-informed care due to their high-level of patient contact. Adequate allocation of resources and investment in staff is essential to ensure such care can be provided. IMPACT: The COVID-19 pandemic has led to adverse physical and mental health outcomes for many. Trauma-informed care is a way to promote reengagement with the healthcare system in this group. Post COVID patients globally may benefit from this approach, as it aims to build trust and independence. PATIENT OR PUBLIC CONTRIBUTION: Feedback was sought from a patient representative to ensure this paper adequately reflected the experience of the post-COVID patient.

Six-week behaviour change intervention to reduce sedentary behaviour in people with chronic obstructive pulmonary disease: a randomised controlled trial.

INTRODUCTION: This study aimed to determine whether a 6-week behaviour change intervention was more effective than a sham intervention for reducing sedentary behaviour (SB) in people with chronic obstructive pulmonary disease (COPD). METHODS: People with stable COPD on the waitlist for entry into pulmonary rehabilitation were recruited to this multicentre trial with randomisation (independent, concealed allocation) to either an intervention group or sham group, assessor blinding and intention-to-treat (ITT) analysis. The behaviour change intervention consisted of once weekly sessions for 6 weeks with a physiotherapist to reduce SB through education, guided goals setting and real-time feedback on SB. The sham intervention consisted of once weekly phone calls for 6 weeks to monitor health status. SB was measured continuously over 7 days using thigh-worn accelerometry (activPAL3 micro). The primary outcome was time spent in SB. Participants with at least 4 days of ≥10 hours waking wear time were included in the ITT analysis and those who reported achieving ≥70% of goals to reduce SB or who completed all sham calls were included in a per-protocol analysis. RESULTS: 70 participants were recruited and 65 completed the study (mean±SD age 74±9 years, mean FEV1 55%±19% predicted, 49% male). At 6 weeks, no between-group differences in time spent in SB were observed in the ITT analysis (mean difference 5 min/day, 95% CI -38 to 48) or per-protocol analysis (-16 min/day, 95% CI -80 to 48). DISCUSSION: A 6-week behaviour change intervention did not reduce time in SB compared with a sham intervention in people with stable moderate-to-severe COPD prior to pulmonary rehabilitation.

Age and Sex Differences in Balance Outcomes among Individuals with Chronic Obstructive Pulmonary Disease (COPD) at Risk of Falls.

No previous research has examined age and sex differences in balance outcomes in individuals with chronic obstructive pulmonary disease (COPD) at risk of falls. A secondary analysis of baseline data from an ongoing trial of fall prevention in COPD was conducted. Age and sex differences were analyzed for the Berg Balance scale (BBS), Balance Evaluation System Test (BEST test) and Activities-specific Balance Confidence Scale (ABC). Overall, 223 individuals with COPD were included. Females had higher balance impairments than males [BBS: mean (SD) = 47 (8) vs. 49 (6) points; BEST test: 73 (16) vs. 80 (16) points], and a lower confidence to perform functional activities [ABC = 66 (21) vs. 77 (19)]. Compared to a younger age (50-65 years) group, age >65 years was moderately associated with poor balance control [BBS (r = - 0.37), BEST test (r = - 0.33)] and weakly with the ABC scale (r = - 0.13). After controlling for the effect of balance risk factors, age, baseline dyspnea index (BDI), and the 6-min walk test (6-MWT) explained 38% of the variability in the BBS; age, sex, BDI, and 6-MWT explained 40% of the variability in the BEST test; And BDI and the 6-MWT explained 44% of the variability in the ABC scale. This study highlights age and sex differences in balance outcomes among individuals with COPD at risk of falls. Recognition of these differences has implications for pulmonary rehabilitation and fall prevention in COPD, particularly among females and older adults.

Priorities and expectations of patients attending a multidisciplinary interstitial lung disease clinic.

BACKGROUND AND OBJECTIVE: The significant and progressive morbidity associated with ILD mean that patients often struggle with the impact of this disease on their QOL and independence. To date, no studies have investigated the importance of multidisciplinary care on patient experience in ILD. We aimed to determine the expectations and priorities of patients attending a tertiary referral centre multidisciplinary ILD clinic. In particular, we sought to learn how important the multidisciplinary element of the clinic was to patients and which aspects of the clinic were most valued. METHODS: An 18-item patient questionnaire was developed in conjunction with expert physicians and specialist nurses involved in the ILD clinic and sent to all patients on the centre's ILD registry at the time of the study (n = 240). Patients rated the importance of different aspects of their experience of attending the clinic. Data collected were analysed using descriptive statistics. Comparisons across disease severity were made using two-sided Z-tests for independent proportions. RESULTS: A total of 100 respondents comprised the study group. Almost all respondents valued the multidisciplinary aspect of the clinic. Obtaining an accurate diagnosis and improving their disease understanding was most important to respondents. The importance of the ILD specialist nurse for both education and support increased with worsening disease severity. CONCLUSION: Our results suggest that a multidisciplinary approach to the management of ILD with additional focus on patient education, as well as tailoring care to disease severity, is a plausible pathway to improving the patient experience with ILD.

Diagnosis and management of connective tissue disease-associated interstitial lung disease in Australia and New Zealand: A position statement from the Thoracic Society of Australia and New Zealand.

Pulmonary complications in CTD are common and can involve the interstitium, airways, pleura and pulmonary vasculature. ILD can occur in all CTD (CTD-ILD), and may vary from limited, non-progressive lung involvement, to fulminant, life-threatening disease. Given the potential for major adverse outcomes in CTD-ILD, accurate diagnosis, assessment and careful consideration of therapeutic intervention are a priority. Limited data are available to guide management decisions in CTD-ILD. Autoimmune-mediated pulmonary inflammation is considered a key pathobiological pathway in these disorders, and immunosuppressive therapy is generally regarded the cornerstone of treatment for severe and/or progressive CTD-ILD. However, the natural history of CTD-ILD in individual patients can be difficult to predict, and deciding who to treat, when and with what agent can be challenging. Establishing realistic therapeutic goals from both the patient and clinician perspective requires considerable expertise. The document aims to provide a framework for clinicians to aid in the assessment and management of ILD in the major CTD. A suggested approach to diagnosis and monitoring of CTD-ILD and, where available, evidence-based, disease-specific approaches to treatment have been provided.

High intensity interval training versus moderate intensity continuous training for people with interstitial lung disease: protocol for a randomised controlled trial.

BACKGROUND: Interstitial lung disease is a debilitating condition associated with significant dyspnoea, fatigue, and poor exercise tolerance. Pulmonary rehabilitation is an effective and key intervention in people with interstitial lung disease. However, despite the best efforts of patients and clinicians, many of those who participate are not achieving clinically meaningful benefits. This assessor-blinded, multi-centre, randomised controlled trial aims to compare the clinical benefits of high intensity interval exercise training versus the standard pulmonary rehabilitation method of continuous training at moderate intensity in people with fibrotic interstitial lung disease. METHODS: Eligible participants will be randomised to either a standard pulmonary rehabilitation group using moderate intensity continuous exercise training or high intensity interval exercise training. Participants in both groups will undertake an 8-week pulmonary rehabilitation program of twice-weekly supervised exercise training including aerobic (cycling) and strengthening exercises. In addition, participants in both groups will be prescribed a home exercise program. Outcomes will be assessed at baseline, upon completion of the intervention and at six months following the intervention by a blinded assessor. The primary outcome is endurance time on a constant work rate test. Secondary outcomes are functional capacity (6-min walk distance), health-related quality of life (Chronic Respiratory Disease Questionnaire (CRQ), St George's Respiratory Questionnaire idiopathic pulmonary fibrosis specific version (SGRQ-I), breathlessness (Dyspnoea 12, Modified Medical Research Council Dyspnoea Scale), fatigue (fatigue severity scale), anxiety (Hospital Anxiety and Depression Scale), physical activity level (GeneActiv), skeletal muscle changes (ultrasonography) and completion and adherence to pulmonary rehabilitation. DISCUSSION: The standard exercise training strategies used in pulmonary rehabilitation may not provide an optimal exercise training stimulus for people with interstitial lung disease. This study will determine whether high intensity interval training can produce equivalent or even superior changes in exercise performance and symptoms. If high intensity interval training proves effective, it will provide an exercise training strategy that can readily be implemented into clinical practice for people with interstitial lung disease.

Changes in Exercise Capacity and Health-Related Quality of Life at Four and Eight Weeks of a Pulmonary Rehabilitation Program in People with COPD.

Pulmonary Rehabilitation (PR) is a key intervention in the management of people with chronic obstructive pulmonary disease (COPD), though few studies have assessed where changes in outcomes occur during a PR program. The aim of this study was to determine the changes in exercise capacity and health-related quality of life at four and eight weeks during a twice-weekly supervised PR program in people with COPD. Fifty participants with COPD were recruited and attended PR twice-weekly for eight weeks. The outcome measures were the endurance shuttle walk test (ESWT), six-minute walk distance (6MWD), St George's Respiratory Questionnaire (SGRQ), COPD Assessment Test (CAT) and the Hospital Anxiety and Depression Scale (HADS) which were measured at baseline, four and eight weeks. Compared to baseline, at week four there were significant improvements in ESWT (mean difference [95%CI] 197 [89 to 305] seconds), 6MWD (22 [8 to 36] metres), SGRQ symptom score (-6 [-12 to -1] points) and SGRQ total score (-4 [-7 to -1] points). Between week four and eight there were further significant improvements in ESWT (94 [8 to 181] seconds) only. By week eight, ESWT, 6MWD, SGRQ symptoms and total score, and CAT had all improved significantly compared to baseline measures. This study demonstrated that participants with moderate to very severe COPD who participated in a twice weekly, eight-week PR program (16 sessions) had significant improvement in ESWT, 6MWD, SGRQ, and CAT score with the greatest improvements occurring in the first four weeks of the program.Supplemental data for this article is available online at https://doi.org/10.1080/15412555.2021.2013793 .

Peer Connect Service for people with pulmonary fibrosis in Australia: Participants' experiences and process evaluation.

BACKGROUND AND OBJECTIVE: People living with pulmonary fibrosis (PF) report unmet needs for information and support. Lung Foundation Australia (LFA) have developed the Peer Connect Service to facilitate telephone support for people with PF across Australia. This project documented the experiences of participants and the resources required to support the service. METHODS: Consenting participants took part in semi-structured interviews by telephone. Primary peers (peers who agreed to initiate contact) and secondary peers (eligible patients who sought a peer match) were interviewed. Thematic analysis was undertaken by two independent researchers. Data were collected on the number of matches and contacts required to establish each match. RESULTS: Interviews were conducted with 32 participants (16 primary peers, 15 secondary peers and 1 who was both), aged from 53 to 89 years with 56% being male. Major themes included the value of shared experiences, providing mutual support and the importance of shared personal characteristics (e.g. gender and hobbies) in allowing information and emotional support needs to be met. Participants saw face-to-face contact with peers as highly desirable whilst acknowledging the practical difficulties. Primary peers were cognizant that their role was not to provide medical advice but to listen and share experiences. In the 12-month period, 60 peer matches were made, each match requiring a minimum of seven staff contacts. CONCLUSION: The Peer Connect Service provides a unique opportunity for people with PF to share experiences and offer mutual support. This telephone matching model may be useful in providing peer support for individuals with rare diseases who are geographically dispersed.

Validity and Responsiveness of the Glittre-ADL Test without a Backpack in People with Chronic Obstructive Pulmonary Disease.

The Glittre-ADL test assesses the functional capacity for activities of daily living of people with chronic obstructive pulmonary disease (COPD). In the test, a weighted backpack is worn (2.5 kg for women and 5.0 kg for men). The differential in weight between men and women is not common in other tests of exercise capacity and may limit the comparison of the test between sexes. The primary aim of this study was to validate the Glittre-ADL test performed without the backpack in people with COPD. Forty participants with mild to severe COPD (mean ± SD age: 70 ± 6 years; FEV1: 48 ± 20%predicted) were recruited and performed two six-minute walk tests (visit 1); two Glittre-ADL tests with backpack (visit 2), and the Glittre-ADL test with and without the backpack, in random order (visit 3). The Glittre-ADL test time was shorter without the backpack than with the backpack [mean difference -0.37 min (95%CI -0.59 to -0.15)] and heart rate (HR) and oxygen saturation (SpO2) were equivalents between tests [-1.31 beats/minute (-3.92 to 1.30) and -0.95% (-2.27 to 0.37), respectively]. The Glittre-ADL test without the backpack elicited similar HR and SpO2 responses as the test with the backpack, indicating equivalence of physiological demand. Thus, the Glittre-ADL test without the backpack was a valid, responsive, and appropriate test to assess functional capacity for activities of daily living.

Oxygen compared to air during exercise training in COPD with exercise-induced desaturation.

Almost half the patients referred to pulmonary rehabilitation with chronic obstructive pulmonary disease (COPD) desaturate during exercise. Although oxygen supplementation may ameliorate oxygen desaturation, the effects on outcomes of exercise training have not been rigorously evaluated. This study aimed to determine whether supplemental oxygen during exercise training was more effective than medical air in improving exercise capacity and health-related quality of life (HRQoL) in people with COPD.People with COPD who demonstrated oxygen desaturation <90% during the 6-min walk test were recruited to this multicentre trial with randomisation (independent, concealed allocation) to either an Oxygen group or Air group, blinding (participants, exercise trainers and European Respiratory Journal assessors) and intention-to-treat analysis. Both groups received the respective gas from concentrators via nasal prongs at 5 L·min-1 during exercise training consisting of treadmill and cycle exercise, three times per week for 8 weeks. Primary outcomes were the endurance shuttle walk test (ESWT) time and Chronic Respiratory Disease Questionnaire (CRQ)-Total score.111 participants (60 males), mean±sd age 69±7 years, with moderate to severe COPD were recruited and 97 completed (Oxygen group n=52; Air group n=45). At the end of the 8-week training programme there were no between-group differences in change in ESWT (mean difference 15 s (95% CI -106-136 s) or change in CRQ-Total (0.0 points (95% CI -0.3-0.3 points)). Within-group changes at end-training were significant for ESWT and CRQ-Total (all p<0.01).Exercise capacity and HRQoL improved in both groups, with no greater benefit from training with supplemental oxygen than medical air.

Maintaining the benefits following pulmonary rehabilitation: Achievable or not?

Pulmonary rehabilitation (PR) improves exercise capacity, health-related quality of life (HRQoL) and dyspnoea in patients with COPD and other lung conditions. Once PR is completed, the benefits gained begin to decline unless patients continue to exercise regularly. Due to limited evidence in other lung conditions, this review aims to examine the current evidence regarding maintenance exercise programmes for patients with COPD and to determine the types of programmes that are able to maintain the benefits gained from PR to 12 months and longer. A number of factors may affect the ability to maintain exercise capacity and HRQoL in the long term including: frequency of supervised maintenance exercise; strategies used to improve adherence to maintenance exercise; facilitators and barriers to long-term exercise training; and initial PR programme itself. The current evidence for maintenance exercise programmes that included supervised maintenance exercise was weak, and for those programmes that included unsupervised maintenance exercise (with and without support) were difficult to interpret and in many instances were no better than usual care. New research using technology has provided some promising results for the future and surveys have revealed important features that may help in the development of maintenance programmes from a participant perspective such as ongoing therapist support. How to best maintain the benefits gained from PR remains unclear. Therefore, it is likely that no one model of maintenance is ideal for all patients with COPD and that individually adapted maintenance exercise programmes need to be considered.

Effects of Ongoing Feedback During a 12-Month Maintenance Walking Program on Daily Physical Activity in People with COPD.

This multi-centred, randomised controlled trial explored the effects of adding ongoing feedback to a 12-month unsupervised maintenance walking program, on daily physical activity (PA) in people with chronic obstructive pulmonary disease. Participants were randomised to either an intervention group (IG) or a usual care group (UCG). During the maintenance program, the IG received ongoing feedback (telephone calls, biofeedback provided via pedometer and progressive goal setting) and the UCG received no feedback. The SenseWear® Pro3 Armband was used to measure PA. Of the 86 participants {IG = 42, (mean [SD]: age 70 [7] years; FEV1 43 [16] % predicted); UCG = 44, (age 69 [9] years; FEV1 44 [15] % predicted)} included at baseline, 43 had sufficient data to be included in the final analysis. There were no between-group differences in any of the PA variables from baseline to completion of the program (all p > 0.05). Ongoing feedback was no more effective than no feedback in improving PA during a 12-month unsupervised walking program.Trial Registration: The trial was registered in the Australia and New Zealand Clinical Trials Registry (ACTRN12609000472279).

The oral health status, behaviours and knowledge of patients with cardiovascular disease in Sydney Australia: a cross-sectional survey.

BACKGROUND: Periodontal disease is a risk factor for atherosclerotic cardiovascular disease and it is recommended internationally that patients with cardiovascular disease should engage in preventative oral health practices and attend regular dental care visits. This study aimed to explore the oral health status, behaviours and knowledge of patients with cardiovascular disease. METHODS: A cross-sectional questionnaire containing 31 items was administered to patients with cardiovascular disease from cardiac rehabilitation and outpatient clinics in Sydney Australia in 2016-2017. RESULTS: Of the 318 patients surveyed, 81.1% reported having at least one oral health problem. Over a third (41.2%) of participants had not seen a dentist in the preceding 12 months and 10.7% had received any oral healthcare information in the cardiac setting. Those with valvular conditions were more likely to have received information compared to those with other cardiovascular conditions (40.6% versus 7.4%, p < 0.001). Only half of the participants had adequate oral health knowledge. CONCLUSIONS: Despite a high incidence of reported oral health problems, many patients lacked knowledge about oral health, were not receiving oral health information from cardiac care providers and had difficulty accessing dental services. Further research is needed to develop oral health strategies in this area.

Pulmonary rehabilitation for patients with acute chronic obstructive pulmonary disease exacerbations: is the evidence strengthening?

PURPOSE OF REVIEW: This manuscript aims to review the most recent evidence about the benefits of early pulmonary rehabilitation commenced during an acute exacerbation in people with COPD (AECOPD). RECENT FINDINGS: A number of RCTs and an observational study, published between 2015 and 2017, have used different exercise interventions compared with usual medical care in people with moderate-to-severe COPD during an AECOPD. The results show short-term improvement in walking distance, muscle strength, quality of life and anxiety and depression. SUMMARY: The evidence about early rehabilitation during AECOPD is growing in strength; however, the outcomes and interventions that were used in the RCTs varied from study to study. Unlike pulmonary rehabilitation for people with stable COPD, there is no ideal model of early rehabilitation for people with AECOPD and little information about long-term benefits, for example, attendance at outpatient-based pulmonary rehabilitation and hospital admissions and length of stay. Because of the risks of deconditioning during an AECOPD and the related healthcare costs, early rehabilitation should commence at the bedside. However, more research is required determine the best way to provide early rehabilitation for people with AECOPD.

Effect on health-related quality of life of ongoing feedback during a 12-month maintenance walking programme in patients with COPD: a randomized controlled trial.

BACKGROUND AND OBJECTIVE: In patients with COPD, this study evaluated the effect on health-related quality of life (HRQoL) of adding ongoing feedback to a 12-month unsupervised maintenance walking programme. METHODS: Participants were randomized to either an intervention group (IG) or control group (CG). Both groups completed the same 2-month supervised, walking training programme followed by a 12-month unsupervised maintenance walking programme. During the maintenance programme, the IG received ongoing feedback (telephone calls, biofeedback and progressive goal setting) and the CG received no feedback. RESULTS: A total of 75 participants completed the study (mean (SD): age 69 (8) years; forced expiratory volume in 1 s (FEV1 ) 43 (15) % predicted). There was no between-group differences in the magnitude of change in HRQoL when data collected on completion of the 12-month maintenance programme were compared with that collected either before the 2-month supervised programme (mean between-group difference (MD) in total St George's Respiratory Questionnaire change scores: 1 point, 95% CI: -9 to 7) or on completion of the 2-month supervised programme (MD: 4 points, 95% CI -2 to 10). CONCLUSION: Following a 2-month supervised walking training programme, ongoing feedback was no more effective than no feedback in maintaining HRQoL during a 12-month unsupervised walking programme.

Is there a learning effect when the 6-minute walk test is repeated in people with suspected pulmonary hypertension?

The aim of the study was to determine if there was a difference in 6-minute walk distance (6MWD) when two 6-minute walk tests (6MWTs) were performed at the initial assessment prior to attendance at the pulmonary hypertension (PH) clinic and at the 6-month follow-up. Two 6MWTs were performed at both visits on a 32-m continuous track in the physiotherapy hospital outpatient setting using standard instructions and encouragement. Two hundred and fourteen participants completed two 6MWTs at the initial assessment and 71 participants at the 6-month follow-up (mean (standard deviation) age: 57 (16) years; body mass index: 27 (6) kg/m2). Using the better 6MWT, the mean distances walked were 429 (136) and 447 (130) m, respectively. There was a significant increase in 6MWD when a second 6MWT was performed at initial assessment (mean difference [95% confidence interval (CI)]: 19 m (14-24), p < 0.001) and at the follow-up (mean difference [95% CI]: 19 m (10-27), p < 0.001) but not in those who walked <300 m at the initial assessment (mean difference [95% CI]: 9 m (-5 to 22), p = 0.208). There were no adverse events during testing. Prior to attendance at the PH Clinic when people are asked to perform the 6MWT for the first time and at the 6-month follow-up, two walk tests should be performed in order to eliminate a learning effect and to ensure accuracy of measurement.

Shuttle walk tests in people with COPD who demonstrate exercise-induced oxygen desaturation: An analysis of test repeatability and cardiorespiratory responses.

Exercise-induced oxygen desaturation (EID) is prevalent in people with chronic obstructive pulmonary disease (COPD). This article reports a sub-analysis from a randomized controlled trial (RCT) in people with COPD and EID (COPD/EID). The primary aim, in people with COPD/ EID, was to determine the repeatability of the distance and time walked in the incremental shuttle walk test (ISWT) and endurance shuttle walk test (ESWT), respectively. A secondary aim was to determine whether any participant characteristics predicted those who did not demonstrate improvements on a repeat ISWT or ESWT. Participants with nadir oxygen saturation (SpO2) < 90% on the 6-minute walk test were recruited to the RCT. Two ISWTs and two ESWTs were then performed as part of the baseline assessments, and participants were included in this sub-analysis if their nadir SpO2 was <90% during the better of two ISWTs. Repeatability of the tests was analysed using Bland-Altman plots and paired t-tests. Participant characteristics of age, lung function, level of nadir SpO2 and end-test dyspnoea were used to predict those who were not likely to demonstrate improvements on a repeat test using receiver operating curves. Eighty-seven participants (mean age (standard deviation, SD) 70 (7) years; forced expiratory volume in one second (FEV1) 47 (17)% predicted) were included. The mean differences (coefficient of repeatability) for the ISWTs and ESWTs were 9 m (55 m) and 19 seconds (142 seconds) respectively ( p < 0.05). No participant characteristic predicted the absence of improvement on the second ISWT (area under the curve (AUC) ranged from 0.49 to 0.58, all p > 0.2) or the second ESWT (AUC ranged from 0.43 to 0.52, all p > 0.3). Although repeating the tests showed only small improvements in distance (ISWT) and time (ESWT) walked in people with COPD/EID, the variability was large making definite conclusions about test repeatability in these individuals difficult.

Australian and New Zealand Pulmonary Rehabilitation Guidelines.

BACKGROUND AND OBJECTIVE: The aim of the Pulmonary Rehabilitation Guidelines (Guidelines) is to provide evidence-based recommendations for the practice of pulmonary rehabilitation (PR) specific to Australian and New Zealand healthcare contexts. METHODS: The Guideline methodology adhered to the Appraisal of Guidelines for Research and Evaluation (AGREE) II criteria. Nine key questions were constructed in accordance with the PICO (Population, Intervention, Comparator, Outcome) format and reviewed by a COPD consumer group for appropriateness. Systematic reviews were undertaken for each question and recommendations made with the strength of each recommendation based on the GRADE (Gradings of Recommendations, Assessment, Development and Evaluation) criteria. The Guidelines were externally reviewed by a panel of experts. RESULTS: The Guideline panel recommended that patients with mild-to-severe COPD should undergo PR to improve quality of life and exercise capacity and to reduce hospital admissions; that PR could be offered in hospital gyms, community centres or at home and could be provided irrespective of the availability of a structured education programme; that PR should be offered to patients with bronchiectasis, interstitial lung disease and pulmonary hypertension, with the latter in specialized centres. The Guideline panel was unable to make recommendations relating to PR programme length beyond 8 weeks, the optimal model for maintenance after PR, or the use of supplemental oxygen during exercise training. The strength of each recommendation and the quality of the evidence are presented in the summary. CONCLUSION: The Australian and New Zealand Pulmonary Rehabilitation Guidelines present an evaluation of the evidence for nine PICO questions, with recommendations to provide guidance for clinicians and policymakers.

A randomised controlled trial of supplemental oxygen versus medical air during exercise training in people with chronic obstructive pulmonary disease: supplemental oxygen in pulmonary rehabilitation trial (SuppORT) (Protocol).

BACKGROUND: Oxygen desaturation during exercise is common in people with chronic obstructive pulmonary disease (COPD). The aim of the study is to determine, in people with COPD who desaturate during exercise, whether supplemental oxygen during an eight-week exercise training program is more effective than medical air (sham intervention) in improving exercise capacity and health-related quality of life both at the completion of training and at six-month follow up. METHODS/DESIGN: This is a multi-centre randomised controlled trial with concealed allocation, blinding of participants, exercise trainers and assessors, and intention-to-treat analysis. 110 people with chronic obstructive pulmonary disease who demonstrate oxygen desaturation lower than 90 % during the six-minute walk test will be recruited from pulmonary rehabilitation programs in seven teaching hospitals in Australia. People with chronic obstructive pulmonary disease on long term oxygen therapy will be excluded. After confirmation of eligibility and baseline assessment, participants will be randomised to receive either supplemental oxygen or medical air during an eight-week supervised treadmill and cycle exercise training program, three times per week for eight weeks, in hospital outpatient settings. Primary outcome measures will be endurance walking capacity assessed by the endurance shuttle walk test and health-related quality of life assessed by the Chronic Respiratory Disease Questionnaire. Secondary outcomes will include peak walking capacity measured by the incremental shuttle walk test, dyspnoea via the Dyspnoea-12 questionnaire and physical activity levels measured over seven days using an activity monitor. All outcomes will be measured at baseline, completion of training and at six-month follow up. DISCUSSION: Exercise training is an essential component of pulmonary rehabilitation for people with COPD. This study will determine whether supplemental oxygen during exercise training is more effective than medical air in improving exercise capacity and health-related quality of life in people with COPD who desaturate during exercise.

The effects of oscillating positive expiratory pressure therapy in adults with stable non-cystic fibrosis bronchiectasis: A systematic review.

Airway clearance techniques (ACTs) are recommended for patients with stable non-cystic fibrosis (non-CF) bronchiectasis, but the efficacy of oscillating positive expiratory pressure (PEP) therapy compared to other techniques has not been reviewed. A systematic review of studies was conducted in stable patients comparing the effect of oscillating PEP therapy to other ACTs or a control condition. Data were extracted related to sputum expectoration, lung function, gas exchange, quality of life (QOL), symptoms, and exacerbation rate. Seven studies were included with a total of 146 patients, with a mean (SD) PEDro score of 7(1). Oscillating PEP therapy enhanced sputum expectoration compared to no treatment, but has equivalent benefits as the active cycle of breathing technique with gravity-assisted drainage (mean difference [95% CI] -2.8 g [-8.8 to 3.2 g]). Oscillating PEP has a similar effect as other ACTs on dynamic lung volumes, gas exchange and breathlessness. Use of oscillating PEP improved disease-specific QOL (p < 0.001) and cough-related QOL (p < 0.002) compared to no treatment but did not reduce exacerbation rate. In conclusion, in stable non-CF bronchiectasis, oscillating PEP therapy is associated with improvement in sputum expectoration and QOL compared to no treatment. Compared to other ACTs, the effect upon sputum expectoration, lung function, gas exchange, and symptoms are equivalent.
