Association between contextual and clinical factors and disability in people with chronic obstructive pulmonary disease

Development of a tool to assess environmental factors to support home care - a Delphi study

BACKGROUND

Living in an adequate environment suited to one's abilities and needs is an essential condition to function in daily life. However, no complete tool currently exists to provide a rapid overview of a person's environment, both material (accommodation and auxiliary means) and social (entourage and available services). Our aim was to develop a tool to identify potentially problematic environmental factors and to determine when an in-depth assessment is necessary.

METHODS

Health professionals experienced in home-based treatment participated in a three-round Delphi process. The first round aimed to define which items the tool should contain, the second to collect participants' opinions on a first version of the tool, and the third to collect the participants' opinions on the adapted version of the tool.

RESULTS

A total of 29 people participated in the first round, 21 in the second and 18 in the third. The final tool contains 205 items divided into four categories (basic information about the inhabitant and their home, inhabitant's level of independence and autonomy, home, tools and means at the inhabitant's disposition) and two annexes (stairs to access to the home, internal staircase to the dwelling).

CONCLUSIONS

A complete tool allowing professionals working in patients' homes to obtain an overview of the environmental factors that could represent obstacles to the independence of the inhabitant, or to the possibility of providing quality care could be developed. This tool is very complete but relatively long. To facilitate its usability, it would be relevant that a digital version to focus on individual relevant categories be elaborated.

Relationship between patient functionality impairment and caregiver burden: is there a cut off point for the severe COPD patient?

BACKGROUND

Chronic obstructive pulmonary disease (COPD) patients experience a progressive limitation of their functionality accompanying their clinical evolution. Concretely, severe COPD patients usually require the figure of a caregiver. Caregiver burden has yet to be explored in other similar chronic diseases. The objective is to propose a cutoff point in different functional impairment aspects, to predict the presence of caregiver burden.

METHODS

Severe COPD patients were divided into two groups according to the caregiver burden, measured with the Zarit Burden Interview (ZBI). The patients were assessed with the London Chest Activity of Daily Living (LCADL) scale, the Functional Independence Measure (FIM), and the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0).

RESULTS

70 COPD patients and their caregivers were included in this cross-sectional study. The ROC curve indicated a cutoff point of 19 in the LCADL scale (AUC = 0.722). Dependence in daily life activities had a cutoff point of 123 in the FIM (AUC = 0.776). Social participation in activities of daily living had a cutoff point of 37 in the WHODAS 2.0 (AUC = 0.739).

CONCLUSION

Dyspnea related to functional status, dependence in daily life activities, and social participation in activities of daily living of severe COPD patients can predict caretaker burden.

Experiences of implementation of the group-based adaptation training intervention for patients with chronic somatic illnesses or disabilities among multi-professional teams in specialized healthcare

OBJECTIVE

To describe the experiences of multi-professional teams of implementation of group-based adaptation training intervention for patients with chronic somatic illnesses or disabilities in specialized healthcare.

MATERIALS AND METHODS

Multi-professional teams (n = 7) implementing adaptation training courses for chronically ill patients in specialised healthcare were interviewed between 09/2020 and 12/2021. The themes for thematic group interviews were based on the standard protocol implementation of adaptation training in specialised healthcare, including planning, implementation and evaluation of the adaptation training courses. The interviews were audio-recorded and transcribed. The data were analysed using inductive content analysis.

RESULTS

The experiences of multi-professional teams involved using pedagogical methods, providing guidance and counselling to support the rehabilitation process, ensuring opportunities for peer support, and supporting the course participants' involvement and activities in everyday life.

CONCLUSIONS

Healthcare professionals should use pedagogical methods in reflective guidance and counselling to promote client-oriented approach in supporting adaptation. Their competence in pedagogy needs to be build and maintained by continuous education. Multi-professional teams need to ensure sufficient and versatile conditions for peer support and involvement of family members by creating open and trusting atmosphere, unhurried encounters, discussions, different and varying ways of working. Adaptation training can strengthen the self-efficacy of participants and help them shift their attention from illness and disability to thoughts of the future. Adaptation training can support active and meaningful daily life in a changed life situation.

Factors associated with participation in life situations in people with COPD

Objective

To examine potential determinants of participation frequency and limitations in people with Chronic Obstructive Pulmonary Disease (COPD).

Methods

For this secondary analysis, we grouped the following factors using the International Classification of Functioning, Disability and Health (ICF) components: age, psychological distress (Hospital Anxiety and Depression Scale (HADS)), gait aid use, supplemental oxygen use, grip strength, modified Medical Research Council Dyspnea scale, Short Physical Performance Battery, and Six-Minute Walk Test (6MWT). Participation was measured using the frequency and limitation domains of the Late Life Disability Instrument (LLDI). Relationships between factors and participation were examined using linear regression.

Results

Ninety-six participants (age 68.7 ± 8.1 yrs; FEV₁ %pred 34 IQR 25–54) were included in the analysis. Factors were linked to four ICF components: activity, body functions, personal, and environmental factors. The final model for LLDI-frequency contained HADS, use of gait aid, and 6MWT (F (3, 81) = 27.69 (p < .001), R² = 0.51), and for LLDI-limitations, the final model included age, HADS, and 6MWT (F (3, 82) = 19.74 (p < .001), R² = 0.42).

Discussion

Participation in life situations in people with COPD is associated with multiple ICF components. Psychological distress (i.e., anxiety and depression symptoms) and mobility were important determinants of participation frequency and limitations. Prospective studies are needed to confirm these relationships.

Validation of the World Health Organization Disability Assessment Schedule (WHODAS 2.0) for individuals with COPD

PURPOSE

COPD fits the profile of disabling health conditions. This study aims to validate the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) in individuals with COPD.

MATERIAL AND METHODS

100 participants with COPD responded to the Brazilian 36-item version of the WHODAS 2.0, as well as the Saint George's Respiratory Questionnaire (SGRQ), and the COPD Assessment Test (CAT). Spirometric data was extracted from medical records.

RESULTS

The internal consistency analysis showed coefficients for all WHODAS 2.0 domains with a strong correlation (0.70-0.85) except for Life activities, which had a moderate correlation (coefficient = 0.60). In the construct analysis, the coefficients for the WHODAS and SGRQ domains presented a consistent correlation among them, varying from 0.40 to 0.69. No correlation was evidenced among the WHODAS domains and the spirometric data, highlighting that linear measures fail when associated with the functioning of an individual with COPD. Discriminative analysis revealed a capacity for the WHODAS 2.0 to distinguish among COPD different levels of clinical impact obtained from CAT excluding the Getting along domain.

CONCLUSION

The WHODAS 2.0 shows as a valid instrument that can sensibly assess functioning differences related to the clinical impact classification level in subjects with COPD.IMPLICATIONS FOR REHABILITATIONWHODAS 2.0 is a valid tool to assess functioning in subjects with COPD.WHODAS 2.0 is sensitive to functioning differences related to classification level and to clinical impact in individuals with COPD.As a Patient-Reported Outcome Measure (PROM), WHODAS 2.0 offers the opportunity to develop clinical patient-centered interventions, improving the health care.As a low-cost, easy-to-use tool, WHODAS can be a useful resource in the process of clinical assessment of patient functioning.
