Lifestyle physical activity in manual wheelchair users - an overlooked public health opportunity.

Public health guidelines and health promotion efforts have traditionally focused on weekly accumulation of moderate to vigorous physical activity (MVPA) via structured exercise. There has been a recent paradigm shift towards the organic incorporation of MVPA in daily leisure and non-leisure time, termed "Lifestyle Physical Activity" (LPA). However, this paradigm shift and the underlying research has neglected manual wheelchair users (MWCUs) with spinal cord injury (SCI), who could benefit from LPA. This article argues for expanding the LPA paradigm shift into research and health promotion efforts involving MWCUs with SCI. We suggest a working definition of LPA for MWCUs and candidate metrics for quantifying LPA. This is followed by brief overviews of LPA correlates, outcomes/consequences, and interventions and the need for theory based approaches to study these domains. We lastly suggest an approach for mitigating potential negative outcomes of increased LPA in MWCUs and suggest a research agenda.

Juggling the management of everyday life activities in persons living with chronic obstructive pulmonary disease.

PURPOSE: Evidence regarding everyday life activities in people living with COPD is limited. Such evidence can improve our understanding when designing interventions for pulmonary rehabilitation that aim at increasing or maintaining participation in these activities. The aim of this study was to describe how people living with COPD experience and manage everyday life activities. MATERIALS AND METHODS: The sample comprised four males and four females with an age ranging from 65-87 years. Participants were interviewed in their own homes regarding experiences of performing and managing everyday life activities. Data were transcribed verbatim and analysed using content analysis. RESULTS: Findings from this study comprised the theme "Juggling to manage everyday life activities with COPD" and three categories representing the elements of this theme: (1) consequences of COPD symptoms, (2) adjustment of activities, and (3) contextual aspects. CONCLUSION: This study found the participants with COPD juggling the management of everyday life activities. The juggle generated a manageable daily life, which came at the expense of making deliberate choices and prioritizing everyday life activities that were necessary for participation in valued and engaging activities in order to maintain health and well-being.Implications for RehabilitationPeople living with COPD experience a complex juggling between the consequences of COPD symptoms and contextual aspects when managing everyday life activities.The participants had largely accepted their disease and adjusted to their situation.The disease was still described as frustrating and generated less focus on making deliberate choices and prioritizing everyday life activities that are necessary for participation in valued and engaging activities.Health professionals need to support people living with COPD in making deliberate choices in order to continue participating in valued and engaging everyday life activities as they affect health and well-being.Pulmonary rehabilitation should focus more on supporting participation in social relations and on using everyday technologies.

New Insights into Activities of Daily Living Performance in Chronic Obstructive Pulmonary Disease.

Purpose: There have been calls for more knowledge of activities of daily living (ADL) performance in order to address interventions in pulmonary rehabilitation effectively. Everyday technology (ET) has become an integrated dimension of ADL, impacting the ways in which ADL is performed. To improve everyday functioning and quality of life, the use of ADL and ET use needs to be evaluated and addressed effectively in interventions. Therefore, the aim of this study was twofold: 1) to explore the quality of ADL performance, and 2) to investigate the relationship between observation and self-reported ADL performance and ability to use everyday technologies in people living with COPD. Methods: This cross-sectional study involved 84 participants aged 46-87 years. Participants were recruited through healthcare centres in the Northern Region of Denmark using a convenience sampling procedure. Data were collected using standardized assessments that investigated different ADL perspectives: self-reported ADL tasks and ET use, observed motor and process ability, and need for assistance. Data were analysed and presented using descriptive statistics and Pearson's correlation coefficient. Results: The most affected ADL tasks were mobility within or outside the home, lower dressing, bathing, pedicuring, cooking, shopping, cleaning and washing clothes. New insights into the quality of ADL performance in people living with COPD were presented in terms of detailed ADL motor skills and ADL process skills, as well as the predicted need for support to function in the community. Moreover, new insights into the relationship between observation and self-reported ADL performance (r=0.546, p<0.01; r=0.297, p<0.01) and between ADL performance and self-perceived ability to use ET (r=0.524, p<0.01; r=0.273, p<0.05; r=0.044, p=0.692) were presented. Conclusion: Overall, the knowledge from the present study is valuable for focusing interventions that address challenging ADL performance and ET use through relevant and realistic activities. The ability to use ET is important to evaluate and target pulmonary rehabilitation.

Activity repertoires and time use in people living with chronic obstructive pulmonary disease.

BACKGROUND: Understanding the dynamics and aspects of how activity choices impact health and well-being in people living with chronic obstructive pulmonary disease (COPD) is important to inform rehabilitation. AIM: To describe, firstly, how much time people living with COPD spend on work, daily living tasks, recreation and rest; secondly, how this population perceived competence, importance and enjoyment related to these activities; thirdly, if differences in such perceptions and time use were associated with the living situation and COPD severity. MATERIAL AND METHODS: This cross-sectional study involved 76 participants (+45 years, COPD, living in ordinary homes), who completed the Occupational Questionnaire (OQ). Descriptive statistics and group comparisons were performed. RESULTS: Most of the participants' time were spent on daily living activities and recreational activities. Participants spent approx. 80% of their recorded time in OQ on activities they valued, enjoyed and in which they felt competent. Participants living alone scored significantly lower on enjoyment in restful activities than those living in couples (p < 0.05). No statistically significant difference in perceived competence, importance or enjoyment was found in relation to COPD severity. CONCLUSIONS AND SIGNIFICANCE: Findings underscore the importance of targeting overall daily activity repertoires including compositions of activity types, time use and perceived competence, importance and enjoyment.

Association Between Everyday Technology Use, Activities of Daily Living and Health-Related Quality of Life in Chronic Obstructive Pulmonary Disease.

Purpose: A decline in the ability to perform activities of daily living (ADL) and ability to use everyday technology can pose threats to independent living, healthcare management and quality of life (QOL) of patients suffering from chronic obstructive pulmonary disease (COPD). Evidence of the relationship between these variables remains limited. The dual aim of this study was, first, to investigate if health-related QOL (HRQOL) was associated with quality in ADL performance and everyday technology use; second, to examine whether lung function, years with COPD diagnosis, living status or educational level affected physical and mental domains of HRQOL. Methods: This cross-sectional study included (N=80) participants aged 46-87 years recruited at healthcare centres in the Northern Region of Denmark using a convenience sampling procedure. Data were gathered through standardized assessments and analysed using multiple regression analysis. Results: The regression model explained 50.6% (R2=0.506) of the variation in HRQOL-physical. The following four variables were statistically significantly associated with HRQOL - physical: years since COPD diagnosis (p=0.023), ability to use everyday technology (p=0.006), amount of relevant everyday technologies (p=0.015) and ADL motor ability (p<0.01). The regression model explained 22.80% (R2=0.228) of HRQOL - mental. Only the variable ability to use everyday technology was statistically significantly associated with HRQOL - mental (p=0.009). Conclusion: Quality of ADL performance and everyday technology use seem to be associated with HRQOL in people living with COPD. The only demographic variable associated with HRQOL was years with COPD. This indicates that healthcare professionals should enhance their attention also to ADL-performance and everyday technology use when striving to increase the HRQOL of persons living with COPD.

Inter-rater and test-retest reliability of the Danish version of the everyday technology use questionnaire.

BACKGROUND: Everyday technologies are naturally integrated in people's daily life. For older adults and adults living with a chronic disease like chronic obstructive pulmonary disease (COPD), the ability to use technologies for health management has become increasingly important. The aim of this study was to investigate inter-rater and test-retest reliability of the Danish version of the Everyday Technology Use Questionnaire (ETUQ) in a sample of older adults with (n = 23) and without (n = 24) COPD. MATERIAL AND METHOD: The ETUQ was initially translated in accordance with the dual panel approach and then administered to a sample of 47 participants. Svensson's method for paired ordinal data was utilized to calculate and analyze reliability. RESULTS: Overall, inter-rater and test-retest reliability of the Danish version of the ETUQ demonstrated excellent percentage agreement (PA) (>75%), although for test-retest reliability, nine items demonstrated fair (53%) to good (73%) agreement. CONCLUSION: This study supports the use of the Danish version of the ETUQ in a sample of older adults with or without COPD. Application to practice: The Danish version of the ETUQ is an evidence-based evaluation that can reliably contribute to clinical occupational therapy and research in Denmark focusing on everyday technology use.

Test-retest and inter-rater reliability of the Danish version of the management of everday technology assessment for use with older adults with and without COPD.

BACKGROUND: The trend towards telemedicine increasingly requires clients to manage everyday technology (ET) to access and use health services. The Management of Everday Technology Assessment (META) is an observation-based instrument developed to evaluate the ability to manage ET. AIM: To examine test-retest (TRR) and inter-rater reliability (IRR) of the Danish translation of the META for older adults with and without COPD. METHOD AND MATERIALS: 47 older adults with COPD (n = 23) and without (n = 24) were recruited. IRR was examined by four raters paired across 30 participants. TRR was examined for 21 participants by the same rater administering the META twice within four weeks. A rank-based method for paired ordinal data was used to calculate percentage agreement (PA) and measures of systematic disagreement and individual variability. Mann Whitney U tests were used to compare PA to health status (presence/absence of COPD). RESULTS: Inter-rater PA was acceptable across 10 of 11 items and test-retest PA across 8 of 11 items. Systematic disagreement was present for one item in TRR. No significant differences in PA were found regarding health status. CONCLUSION: The Danish META generates reliable scores for this sample. However, conclusive statements cannot be made for all items.

Causes of misdiagnosis of chronic obstructive pulmonary disease: A systematic scoping review.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) has serious implications at both the individual and the societal level. It is crucial that COPD is diagnosed correctly to ensure provision of the right treatment. However, the current diagnostic procedures may lead to misdiagnosis. AIM: The aim of this scoping review was to disseminate knowledge about potential causes of misdiagnosis of COPD. METHODS: A systematic, comprehensive search was performed in PubMed, Embase and Cinahl. RESULTS: A thorough review produced a sample of 73 articles. The synthesis revealed five potential causes of misdiagnosis of COPD, including: the threshold for defining COPD (n = 36), errors made in primary care (n = 15), errors linked to the spirometry test (n = 13), differential diagnoses (n = 10), and patient-related factors (n = 8). CONCLUSIONS: The causes of misdiagnosis of COPD are attributable mainly to spirometry and to the healthcare professional performing the diagnostic assessment. With a view to limiting misdiagnosis of COPD, future research should help clarify strategies for alternative objective tests for determining if a patient has COPD and explore how to better support primary care in the diagnosing of COPD.

Transforming paper-based assessment forms to a digital format: Exemplified by the Housing Enabler prototype app.

BACKGROUND: The aim of this paper is to provide the reader with an overall impression of the stepwise user-centred design approach including the specific methods used and lessons learned when transforming paper-based assessment forms into a prototype app, taking the Housing Enabler as an example. METHODS: Four design iterations were performed, building on a domain study, workshops, expert evaluation and controlled and realistic usability tests. The user-centred design process involved purposefully selected participants with different Housing Enabler knowledge and housing adaptation experience. RESULTS: The design iterations resulted in the development of a Housing Enabler prototype app. The prototype app has several features and options that are new compared with the original paper-based Housing Enabler assessment form. These new features include a user friendly overview of the assessment form; easy navigation by swiping back and forth between items; onsite data analysis; and ranking of the accessibility score, photo documentation and a data export facility. CONCLUSION: Based on the presented stepwise approach, a high-fidelity Housing Enabler prototype app was successfully developed. The development process has emphasized the importance of combining design participants' knowledge and experiences, and has shown that methods should seem relevant to participants to increase their engagement.

Combining apps targeting professionals and senior citizens to improve housing accessibility and influence housing provision policies.

Two separate apps that address the increasingly important issue of accessible housing for senior citizens have been developed in different project settings. One of the apps was developed to facilitate the process for professional raters to assess housing accessibility in the context of individual housing adaptations. The other app was developed for senior citizens to raise their awareness of possible accessibility problems in their current dwelling and in other apartments within the available housing stock. Both apps were developed with a high degree of active user involvement in processes utilizing multiple state of the art methods. The results are two well accepted prototype apps perceived as user-friendly and appropriate for the intended user groups. By combining these two apps, our ambition is for the professional raters to benefit by gaining knowledge of their clients' perceived needs and desires, and for senior citizens to benefit by getting access to a database of professionally rated dwellings. The ultimate goal is the generation of sound knowledge reflecting the needs and desires of senior citizens and professional requirements regarding accessible housing as a means to inform and influence housing provision policies.

The Nordic Housing Enabler: Inter-rater reliability in cross-Nordic occupational therapy practice. Previously published in Scandinavian Journal of Occupational Therapy 2010; 17: 258-266.

This study addresses development of a content-valid cross-Nordic version of the Housing Enabler and investigation of its inter-rater reliability when used in occupational therapy rating situations, involving occupational therapists, clients, and their home environments. The instrument was translated from the original Swedish version of the Housing Enabler, and adapted according to accessibility norms and guidelines for housing design in Sweden, Denmark, Finland, and Iceland. This iterative process involved occupational therapists, architects, building engineers, and professional translators, resulting in the Nordic Housing Enabler. For reliability testing, the sampling strategy and data collection procedures used were the same in all countries. Twenty voluntary occupational therapists, pair-wise but independently of each other, collected data from 106 cases by means of the Nordic Housing Enabler. Inter-rater reliability was calculated by means of percentage agreement and kappa statistics. Overall good percentage agreement for the personal and environmental components of the instrument was shown, indicating that the instrument was sufficiently reliable for application in practice and research in the Nordic context. The varying kappa results highlight the need for further study in order to understand the influence of prevalence more profoundly, which should be kept in mind when interpreting the results.

Validation of housing standards addressing accessibility: exploration of an activity-based approach.

The aim was to explore the use of an activity-based approach to determine the validity of a set of housing standards addressing accessibility. This included examination of the frequency and the extent of accessibility problems among older people with physical functional limitations who used no mobility device (n = 10) or who used a wheelchair (n = 10) or a rollator (n = 10). The setting was a kitchen designed according to present housing standards. The participants prepared lunch in the kitchen. Accessibility problems were assessed by observation and self-report. Differences between the three participant groups were examined. Performing well-known kitchen activities was associated with accessibility problems for all three participant groups, in particular those using a wheelchair. The overall validity of the housing standards examined was poor. Observing older people interacting with realistic environments while performing real everyday activities seems to be an appropriate method for assessing accessibility problems.

Test-retest reliability and agreement of the Satisfaction with the Assistive Technology Services (SATS) instrument in two Nordic countries.

PURPOSE: The purpose of this study was to investigate test-retest reliability, agreement, internal consistency, and floor- and ceiling effects of the Danish and Finnish versions of the Satisfaction with the Assistive Technology Services (SATS) instrument among adult users of powered wheelchairs (PWCs) or powered scooters (scooters). METHOD: Test-retest design, two telephone interviews 7-18 days apart of 40 informants, with mean age of 67.5 (SD 13.09) years in the Danish; and 54 informants with mean age of 55.6 (SD 12.09) years in the Finnish sample. RESULTS: The intra-class correlation coefficient varied between 0.57 and 0.93 for items in the Danish and between 0.41 and 0.93 in the Finnish sample. The percentage agreement varied between 54.2 and 79.5 for items in the Danish and between 69.2 and 81.1 in the Finnish sample, while the Cronbach's alpha values varied between 0.87 and 0.96 in the two samples. A ceiling effect was found in all items of both samples. CONCLUSIONS: This study indicates that the SATS may be reliably administered for telephone interviews among adult PWC and scooter users, and give information about aspects of the service delivery process for quality development improvement purposes. Further psychometric testing of the SATS is required.

Unfolding the phenomenon of interrater agreement: a multicomponent approach for in-depth examination was proposed.

OBJECTIVE: The overall objective was to unfold the phenomenon of interrater agreement: to identify potential sources of variation in agreement data and to explore how they can be statistically accounted for. The ultimate aim was to propose recommendations for in-depth examination of agreement to improve the reliability of assessment instruments. STUDY DESIGN AND SETTING: Using a sample where 10 rater pairs had assessed the presence/absence of 188 environmental barriers by a systematic rating form, a raters × items data set was generated (N=1,880). In addition to common agreement indices, relative shares of agreement variation were calculated. Multilevel regression analysis was carried out, using rater and item characteristics as predictors of agreement variation. RESULTS: Following a conceptual decomposition, the agreement variation was statistically disentangled into relative shares. The raters accounted for 6-11%, the items for 32-33%, and the residual for 57-60% of the variation. Multilevel regression analysis showed barrier prevalence and raters' familiarity with using standardized instruments to have the strongest impact on agreement. CONCLUSION: Supported by a conceptual analysis, we propose an approach of in-depth examination of agreement variation, as a strategy for increasing the level of interrater agreement. By identifying and limiting the most important sources of disagreement, instrument reliability can be improved ultimately.

Lack of research-based standards for accessible housing: problematization and exemplification of consequences.

OBJECTIVE: To increase the understanding of how definitions of standards for housing design influence the proportion of dwellings not meeting the standards and the proportion of individuals defined as having accessibility problems. METHODS: The sample included old people and their dwellings in three European countries (N = 1,150). Frequencies and percentages were reported and empirical distribution functions were used. RESULTS: Depending on the functional profile and standards in question, the magnitude of influence of the standards differs in extent, e.g., the existing standard for door openings at the entrance (defined ≥75 cm) implied that the proportion of dwellings not meeting it was 11.3% compared to 64.4%, if the standard was set to ≥83 cm. The proportion of individuals defined as having accessibility problems for profiles not using mobility devices was 4-5, 57% for profiles using them and 1-3% for the total sample if the standard was set to 90 cm. CONCLUSION: Research-based standard definitions for housing design are necessary to ensure that they actually lead to enhanced accessibility, which is a prerequisite for the independence and health of persons with functional limitations.
