Exercise testing
Title: Prescription of Walking Exercise Intensity from the Incremental Shuttle Walk Test in
People with Chronic Obstructive Pulmonary Disease. Authors: Zainuldin R, Mackey MG, Alison
JA. Source: Am J Phys Med Rehabil. 2012 Jan 26. [Epub ahead of print]. Summary: This study
determined the intensity of walking exercise prescribed from 70% of peak speed achieved
during the incremental shuttle walk test (ISWT) in people with COPD and whether a
steady-state response was achieved when exercising at this intensity. Zainuldin et al. concluded
that prescription of walking exercise at 70% of the peak ISWT speed provided an intensity
appropriate for achieving physiologic training responses.
Title: Prevalence and Prediction of Exercise-Induced Oxygen Desaturation in Patients with
Chronic Obstructive Pulmonary Disease. Authors: van Gestel AJ, Clarenbach CF, Stöwhas AC,
Teschler S, Russi EW, Teschler H, Kohler M. Source: Respiration. 2012 Jan 20. [Epub ahead of
print]. Summary: Van gestel et al. measured FEV(1), DLCO, SpO(2) at rest and during a 6-min
walking test as well as physical activity by an accelerometer. A drop in SpO(2) of >4 to <90%
was defined as exercise-induced desaturation. Exercise-induced desaturation is highly
prevalent among patients with COPD and can be predicted by FEV(1).
Title: Interstitial Lung Abnormalities and Reduced Exercise Capacity. Authors: Doyle TW,
Washko GR, Fernandez IE, Nishino M, Okajima Y, Yamashiro T, Divo MJ, Celli BR, Sciurba
FC, Silverman EK, Hatabu H, Rosas IO, Hunninghake GM; for the COPDGene Investigators.
Source: Am J Respir Crit Care Med. 2012 Jan 20. [Epub ahead of print]. Summary: This study
aimed to assess the validity of the six-minute walk test (6MWT) in subjects with interstitial lung
abnormalities (ILA) and to examine the association between ILA and six minute walk distance
(6MWD).This study demonstrates that ILA are associated with measurable decrements in the
6MWD of smokers.
Pulmonary rehabilitation and exercise training
Title: Uptake of pulmonary rehabilitation in New Zealand by people with chronic obstructive
pulmonary disease in 2009. Authors: Levack WM, Weatherall M, Reeve JC, Mans C, Mauro A.
Source: N Z Med J. 2012 Jan 20;125(1348):23-33. Summary: This study aimed to estimate the
uptake of pulmonary rehabilitation by people with COPD in New Zealand in 2009.Levack et al.
concluded that there is a marked shortfall between the national levels of provision of pulmonary
rehabilitation and the prevalence of COPD, with less than 1% of people with COPD participating
in pulmonary rehabilitation each year in New Zealand. Incentives, leadership and coordination
of services are required at a national level to increase the uptake of PR.

Title: Tests of the Responsiveness of the Chronic Obstructive Pulmonary Disease (COPD)
Assessment Test TM (CAT) Following Acute Exacerbation and Pulmonary Rehabilitation.
Authors: Jones PW, Harding G, Wiklund I, Berry P, Tabberer M, Yu R, Leidy NK. Source:
Chest. 2012 Jan 26. [Epub ahead of print]. Summary: Study 1 assessed CAT responsiveness to
changes in health status in 67 patients during an exacerbation, (Days 1-14). Study 2 assessed
CAT responsiveness in 64 patients undergoing pulmonary rehabilitation, (Days 1-42).
Correlations between CAT and other outcome measures were examined. These studies
indicate that the CAT is sensitive to changes in health status following exacerbations and is as
responsive to pulmonary rehabilitation as more complex COPD health status measures.
Title: Effect of upper extremity exercise in people with COPD. Authors: Kathiresan G,
Jeyaraman SK, Jaganathan J. Source: J Thorac Dis. 2010 Dec;2(4):223-36. Summary: This
review suggests that in the short term, arm endurance training improves arm exercise capacity
and arm strength training improves arm strength. Further research is required, in people with
COPD, to investigate the long-term effects of arm training.
Daily physical activity levels
Title: Prognostic value of the objective measurement of daily physical activity in COPD patients.
Authors: Garcia-Rio F, Rojo B, Casitas R, Lores V, Madero R, Romero D, Galera R, Villasante
C. Source: Chest. 2012 Jan 26. [Epub ahead of print]. Summary: Garcia-Rio et al. evaluated the
capacity of the objective measurement of daily physical activity in COPD patients using
accelerometers to estimate their prognostic value. In conclusion, the objective measurement of
the daily physical activity in COPD patients using an accelerometer constitutes an independent
prognostic factor for mortality and hospitalization due to severe exacerbation.
Patient education
Title: Self-care 3 months after attending chronic obstructive pulmonary disease patient
education: a qualitative descriptive analysis. Authors: Mousing CA, Lomborg K. Source: Patient
Prefer Adherence. 2012;6:19-25. Epub 2012 Jan 4. Summary: The authors performed a
qualitative descriptive analysis to explore how group patient education influences the self-care
of patients with chronic obstructive pulmonary disease. Patients' self-care may be enhanced
through group education, even though the patients are not always able to see the immediate
outcome. Some patients may require professional help to implement their newly acquired
knowledge and skills in everyday life. A planned dialogue concentrating on self-care in everyday
life 3 months after finishing the course may enhance patients' awareness and appraisal of their
newly acquired competencies.

Title: Does a Self-management Education Program Have the Same Impact on Emotional and
Functional Dimensions of HRQoL? Authors: Moullec G, Favreau H, Lavoie KL, Labrecque M.
Source: COPD. 2012 Jan 17. [Epub ahead of print]. Summary: This study was a secondary
analysis of a prospective study that compared the efficacy of a self-management education
program (SM) on emotional and functional dimensions of HRQoL. Only the emotional dimension
scores of both the SGRQ (impact) and the SF-36 (mental component summary) were
statistically and clinically improved in the SM group compared to UC.
Tele-care
Title: Moving prediction of exacerbation in chronic obstructive pulmonary disease for patients in
telecare. Authors: Jensen MH, Cichosz SL, Dinesen B, Hejlesen OK. Source: J Telemed
Telecare. 2012 Jan 20. [Epub ahead of print]. Summary: Jensen et al. investigated whether
physiological data can be used for predicting COPD exacerbations. The authors concluded that
a system capable of predicting risk could provide support to COPD patients in their
tele-rehabilitation.
Title: CHRONIOUS: A wearable platform for monitoring and management of patients with
chronic disease. Authors: Bellos C, Papadopoulos A, Rosso R, Fotiadis DI. Source: Conf Proc
IEEE Eng Med Biol Soc. 2011 Aug;2011:864-7. Summary: This article describes the
CHRONIOUS system, which has been developed based on an open architecture design that
consists of a set of subsystems which interact in order to provide all the needed services to the
chronic disease patients. The integrated platform provides real-time patient monitoring and
supervision, both indoors and outdoors and represents a generic platform for the management
of various chronic diseases.
Title: Outcomes of a Telehealth Intervention for Homebound Older Adults With Heart or Chronic
Respiratory Failure: A Randomized Controlled Trial. Authors: Gellis ZD, Kenaley B, McGinty J,
Bardelli E, Davitt J, Ten Have T. Source: Gerontologist. 2012 Jan 11. [Epub ahead of print].
Summary: Gellis et al. report on a randomized controlled trial examining the impact of a
multifaceted telehealth intervention on health, mental health, and service utilization outcomes
among homebound medically ill older adults diagnosed with CHF or COPD. In conclusion,
telehealth may be an efficient and effective method of systematically delivering integrated care
in the home health sector. The use of telehealth technology may benefit homebound older
adults who have difficulty accessing care due to disability, transportation, or isolation.

Title: Impact of Anxiety and Depression on COPD Exacerbation Risk. Authors: Laurin C,
Moullec G, Bacon SL, Lavoie KL. Source: Am J Respir Crit Care Med. 2012 Jan 12. [Epub
ahead of print]. Summary: This paper reviews the current literature and quantify the prospective
impact of anxiety and depression on exacerbation risk in patients with COPD. The limitations of
the existing literature and the perspectives for future research will be addressed.
End-of-life communication
Title: The Effect of End-of-Life Discussions on Perceived Quality of Care and Health Status
Among Patients with COPD. Authors: Leung JM, Udris EM, Uman J, Au DH. Source: Chest.
2012 Jan 12. [Epub ahead of print]. Summary: The objective was to determine whether COPD
patients who reported having had end-of-life discussions also reported higher perceived
markers of quality of care and health status. Patients who reported having end-of-life care
discussions with their clinicians have higher perceived quality of care and satisfaction with their
clinicians. Discussing end-of-life care with patients who have COPD may improve their
perceived overall quality of and satisfaction with care.
