Use of functional independence measure in rehabilitation of inpatients with respiratory failure

The Impact of Pulmonary Rehabilitation in Acute Exacerbation of Chronic Obstructive Pulmonary Disease (COPD): A Case Report

This study focuses on a 56-year-old male laborer who presented to the respiratory department with grade III dyspnea persisting for 20 days, aggravated in the mornings, accompanied by chest pain over the last two days. The patient reported a productive cough producing yellowish sputum for 15 days and an ongoing fever during this period. With a two-year medical history of seasonal bronchial asthma, the patient had been using an inhaler three times daily for the past month. Additionally, a 20-year history of smoking, averaging five cigarettes per day, was disclosed. Investigations revealed hyperinflation of the lungs on X-ray, indicative of an acute exacerbation of chronic obstructive pulmonary disease (AECOPD). The patient was prescribed a four-week pulmonary rehabilitation protocol, incorporating physiotherapy. Baseline assessments were conducted using outcome measures such as pulmonary function test (PFT), functional independence measure (FIM), and six-minute walk distance (6MWD) before initiating treatment to evaluate the patient's performance. Following the prescribed pulmonary rehabilitation regimen, notable improvements were observed in PFT, FIM, and 6MWD. These findings underscore significant enhancements in exercise tolerance and overall functional capacity. The results suggest that a structured pulmonary rehabilitation program can lead to meaningful clinical benefits in individuals experiencing AECOPD, particularly when tailored to individual patient needs and characteristics.

Clinical Effects of Pulmonary Rehabilitation in Very Old Patients with COPD

Background: Pulmonary rehabilitation (PR) improves physical and mental performance as well as quality of life in patients with chronic obstructive pulmonary disease (COPD). However, data on outcomes in very old patients are insufficient. We analyzed whether the elderly with COPD benefit in a similar way to younger patients from participation in an inpatient PR according to the assessments usually collected. Methods: Data from 3173 patients with COPD were retrospectively analyzed. Patients were referred to PR at the Zurich RehaZentren, Switzerland, between January 2013 and December 2019. PR was performed 6 days per week with an average duration of 18.85 days. Functional Independence Measurement (FIM), Feeling Thermometer (FT), and 6-Minute Walk Test (6MWT) were recorded on admission and discharge. Results: In all age groups, the 6MWT and FT improved significantly. FIM results also showed a significant increase. The results of the different age groups showed no significant differences in percentage improvements according to the assessments that were considered. Conclusions: All patient groups with COPD, even the oldest (>85 years), benefited from PR regardless of their age and according to the assessments. Prospective studies are needed to support this hypothesis.

Analysis of the effect of patients' health status on efficiency: Application of data envelopment analysis in healthcare

The effective and efficient operation of public healthcare systems is more and more important as a consequence of the increasing amount of money spent on their operation. For this reason, accurate and science-based efficiency information is needed for managers and healthcare policy makers. The evaluation of the efficiency in this sector is particularly difficult because several measures and indicators are used. Data envelopment analysis (DEA) can provide aggregate and overall measures of efficiency. The purpose of this paper is the examination of the efficiency of in-patient rehabilitation units curing musculoskeletal disorders in Hungary. The research presented focuses on rehabilitation units which attend to patients recovering from stroke or other acquired brain injuries. Output-oriented, slack-based DEA models are applied for the evaluation of in-patient rehabilitation units using data of a national survey. The novelty of the method presented is the consideration of the change in patients' functional status when efficiency is evaluated using DEA.

Respiratory rehabilitation in patients recovering from severe acute respiratory syndrome: A systematic review and meta-analysis

BACKGROUND

With an increase in published reports on respiratory rehabilitation (RR) in severe acute respiratory syndrome (SARS), there is a need for a meta-analysis and systematic review to measure the effects of the RR in SARS.

OBJECTIVE

Objective of the review was to evaluate the efficacy and safety of RR in patients recovering from SARS.

METHODS

PubMed/ MEDLINE, CENTRAL, EMBASE, and Clinical Trial Registries were systematically searched (between January 1, 2003, to July 31, 2021) to identify all patients who received RR, at least for six days, following SARS. The primary outcome was exercise capacity [6-meter walking distance (6-MWD)], and secondary outcomes were change in pulmonary function test (PFT) parameters, activities in daily livings (ADLs), and quality of life (QoL). Meta-analysis was performed by using RevMan 5.4.

RESULTS

Twenty-one observational studies, including eight comparative studies, were included. Eight comparative studies participated in quantitative meta-analysis. The intervention group, who received RR, improved significantly in exercise capacity (6-MWD) [mean difference (MD):45.79, (95% CI:31.66-59.92)] and PFT parameters, especially in forced vital capacity (FVC%) [MD:4.38, (95% CI:0.15-8.60)], and diffusion lung capacity for carbon monoxide (DLCO%) [MD:11.78, (95% CI:5.10-18.46)]. The intervention group failed to demonstrate significant improvement in ADLs and QoL outcomes. No significant adverse events were reported during the intervention.

CONCLUSION

Respiratory rehabilitation can improve exercise capacity and PFT parameters in patients recovering from SARS infection. The RR does not cause serious adverse events. Clinical trials to determine the best RR program (in terms of initiation, duration, and components) in SARS and its treatment efficacy, both in the short and long- term are needed.

COVID-19 cognitive deficits after respiratory assistance in the subacute phase: A COVID-rehabilitation unit experience

INTRODUCTION

COVID-19 complications can include neurological, psychiatric, psychological, and psychosocial impairments. Little is known on the consequences of SARS-COV-2 on cognitive functions of patients in the sub-acute phase of the disease. We aimed to investigate the impact of COVID-19 on cognitive functions of patients admitted to the COVID-19 Rehabilitation Unit of the San Raffaele Hospital (Milan, Italy).

MATERIAL AND METHODS

87 patients admitted to the COVID-19 Rehabilitation Unit from March 27th to June 20th 2020 were included. Patients underwent Mini Mental State Evaluation (MMSE), Montreal Cognitive Assessment (MoCA), Hamilton Rating Scale for Depression, and Functional Independence Measure (FIM). Data were divided in 4 groups according to the respiratory assistance in the acute phase: Group1 (orotracheal intubation), Group2 (non-invasive ventilation using Biphasic Positive Airway Pressure), Group3 (Venturi Masks), Group4 (no oxygen therapy). Follow-ups were performed at one month after home-discharge.

RESULTS

Out of the 87 patients (62 Male, mean age 67.23 ± 12.89 years), 80% had neuropsychological deficits (MoCA and MMSE) and 40% showed mild-to-moderate depression. Group1 had higher scores than Group3 for visuospatial/executive functions (p = 0.016), naming (p = 0.024), short- and long-term memory (p = 0.010, p = 0.005), abstraction (p = 0.024), and orientation (p = 0.034). Group1 was younger than Groups2 and 3. Cognitive impairments correlated with patients' age. Only 18 patients presented with anosmia. Their data did not differ from the other patients. FIM (<100) did not differ between groups. Patients partly recovered at one-month follow-up and 43% showed signs of post-traumatic stress disorder.

CONCLUSION

Patients with severe functional impairments had important cognitive and emotional deficits which might have been influenced by the choice of ventilatory therapy, but mostly appeared to be related to aging, independently of FIM scores. These findings should be integrated for correct neuropsychiatric assistance of COVID-19 patients in the subacute phase of the disease, and show the need for long-term psychological support and treatment of post-COVID-19 patients.

Role of Rehabilitation Department for Adult Individuals With COVID-19: The Experience of the San Raffaele Hospital of Milan

The rapid evolution of the health emergency linked to the spread of severe acute respiratory syndrome coronavirus 2 requires specifications for the rehabilitative management of patients with coronavirus disease 2019 (COVID-19). The symptomatic evolution of patients with COVID-19 is characterized by 2 phases: an acute phase in which respiratory symptoms prevail and a postacute phase in which patients can show symptoms related to prolonged immobilization, to previous and current respiratory dysfunctions, and to cognitive and emotional disorders. Thus, there is the need for specialized rehabilitative care for these patients. This communication reports the experience of the San Raffaele Hospital of Milan and recommends the setup of specialized clinical pathways for the rehabilitation of patients with COVID-19. In this hospital, between February 1 and March 2, 2020, about 50 patients were admitted every day with COVID-19 symptoms. In those days, about 400 acute care beds were created (intensive care/infectious diseases). In the following 30 days, from March 2 to mid-April, despite the presence of 60 daily arrivals to the emergency department, the organization of patient flow between different wards was modified, and several different units were created based on a more accurate integration of patients' needs. According to this new organization, patients were admitted first to acute care COVID-19 units and then to COVID-19 rehabilitation units, post-COVID-19 rehabilitation units, and/or quarantine/observation units. After hospital discharge, telemedicine was used to follow-up with patients at home. Such clinical pathways should each involve dedicated multidisciplinary teams composed of pulmonologists, physiatrists, neurologists, cardiologists, physiotherapists, neuropsychologists, occupational therapists, speech therapists, and nutritionists.

Inpatient Pulmonary Rehabilitation Program in a Long-Term Care Facility: Short-Term Outcomes and Patient Satisfaction

The purpose of the current study was to evaluate short-term outcomes of inpatient pulmonary rehabilitation (IPR) programs for older patients with chronic obstructive pulmonary disease (COPD). IPR comprises medical management, exercise, nutrition counseling, and coping skills education programs, among other interventions. The current study used a pretest-posttest design with 21 participants evenly split by gender between the ages of 46 and 95. Effects of IPR on functional tolerance exercise capacity and perceived dyspnea on exertion level had a statistically significant difference by the end of the program. Scores for health-related quality of life and subscales of symptoms, impact, and activity in participants younger than 65 were not statistically significant, whereas St. George's Respiratory Questionnaire scores for participants older than 65 showed a statistically significant improvement. Results showed that early IPR is an effective intervention for the management of symptoms of COPD in older adults recovering from a COPD exacerbation.

Interactive videogame as rehabilitation tool of patients with chronic respiratory diseases: preliminary results of a feasibility study

OBJECTIVE

To evaluate the effectiveness of an interactive videogame (IV) system in addition to a supervised pulmonary rehabilitation programme (PRP) in patients with chronic respiratory diseases.

DESIGN

Randomised Controlled Trial comparing standard PRP (20 patients, control group: CG), and PRP + sessions of interactive videogame-aided exercises (20 patients, experimental group: EG). Lung and respiratory muscle function, arterial blood gases, exercise capacity, dyspnoea, health status and health-related quality of life (HRQL) and emotional response were measured before and after PRP. A questionnaire on acceptability of the PRP was administered.

RESULTS

Exercise capacity, dyspnoea and HRQL significantly improved in both groups after the PRP, whereas the EG showed a greater improvement in six-minute walk test and transitional dyspnoea index than the CG. No difference in psychological status or acceptability of PRP was observed between the two groups.

CONCLUSIONS

The addition of IV training was more effective for improving some parameters of exercise tolerance and dyspnoea, although did not result in better psychological status nor it was better accepted than the standard PRP in patients with chronic respiratory diseases.

Measurement of activities of daily living in patients with COPD: a systematic review

BACKGROUND

The objectives of this systematic review were to synthesize the literature on measures of activities of daily living (ADLs) that have been used in individuals with COPD and to provide an overview of the psychometric properties of the identified measures and describe the relationship of the disease-specific instruments with other relevant outcome measures for individuals with COPD and health-care use.

METHODS

Studies that included a measure of ADLs in individuals with COPD were identified using electronic and hand searches. Two investigators performed the literature search. One investigator reviewed the study title, abstract, and full text of the articles to determine study eligibility and performed the data extraction and tabulation. In cases of uncertainty, a second reviewer was consulted.

RESULTS

A total of 679 articles were identified. Of those, 116 met the inclusion criteria. Twenty-seven ADLs instruments were identified, of which 11 instruments were respiratory disease-specific, whereas 16 were generic. Most instruments combined instrumental ADLs (IADLs) with basic ADLs (BADLs). The majority of the instruments were self-reported; only three instruments were performance based. Twenty-one studies assessed psychometric properties of 16 ADLs instruments in patients with COPD.

CONCLUSIONS

Although several ADLs instruments were identified, psychometric properties have only been reported in a few. Selection of the most appropriate measure should focus on the target construct (BADLs or IADLs or both), type of test (disease-specific vs generic and self-reported vs performance-based), depth of information obtained, and psychometric properties of the instruments. Given the relevance of ADLs to the lives of patients with COPD, its assessment should be more frequently incorporated as a clinical outcome in their management.

Family caregiver perspectives on caring for ventilator-assisted individuals at home

BACKGROUND

The trend of patients who are invasively ventilated to prefer home care is one that benefits both the patient and the health care system. However, this assumes a role for patients' family members to become informal caregivers.

OBJECTIVE

To explore the impact of caring for a ventilator-assisted individual on informal caregivers.

METHODS

A descriptive design with semistructured caregiver interviews and the Caregiver Burden Inventory were used. Participants were informal caregivers of a family member with a progressive neuromuscular disease on invasive ventilation for at least six months. Transcript coding was performed and regularly reviewed, and recruitment continued until data saturation. Qualitative analysis was based on 'thematic analysis'.

RESULTS

A total of 21 caregivers were interviewed. Five themes developed: a sense of duty; restriction of day-to-day life; physical and emotional burden; training and education; and the need for more paid support. Caregivers described a sense of duty to take care of loved ones, but suffered a significant restriction of their own time with a negative impact on their physical and mental health. The initial transfer home was highlighted as the most stressful part of the process. The Caregiver Burden Inventory scores supported a high level of burden: median 49 (interquartile range 39.5 to 53.0) of a maximum 96.

CONCLUSION

Homecare for ventilator-assisted individuals with progressive neuromuscular disease causes significant burden to informal caregivers. Approaches to lessen this burden, such as increased paid care, improved professional support and respite care, may enable home ventilation to be a more sustainable modality of care.

Factors influencing self-management in chronic obstructive pulmonary disease: an integrative review

BACKGROUND

Chronic obstructive pulmonary disease is a common, chronic and burdensome condition requiring the individual to engage in a range of self-management strategies. The capacity to engage in self-management is dependent on a range of internal (e.g., personal) and external (e.g., health service) factors.

OBJECTIVES

This paper seeks to define self-management, identify the determinants which influence the individual's ability to cope and adjust to living with chronic obstructive pulmonary disease in the community, and identify implications for clinical practice and research.

DESIGN

Integrative review.

DATA SOURCES

Medline, Embase, PubMed, CINAHL, Google Scholar.

REVIEW METHODS

Integrative review using prospective research questions. Papers were included in the review if they were published in peer reviewed journals and written in English between 2000 and 2010. Articles were accepted for inclusion if they discussed the determinants that influenced self-management of chronic obstructive pulmonary disease in the community. Confirmation of results and discussion themes was validated by specialists in chronic obstructive pulmonary disease and complex care.

FINDINGS

Self-management is less well characterised in chronic obstructive pulmonary disease compared with other chronic conditions. Functional limitation and the need to balance disease management with everyday life are the two key elements that patients face in managing their condition. Provider characteristics, socioeconomic status and health literacy are sparsely discussed yet are known to influence chronic obstructive pulmonary disease self-management.

CONCLUSIONS

Chronic obstructive pulmonary disease self-management must be a key focus internationally as the disease incidence increases. Collaborative care is required between patients and health providers in order facilitate patients in confident management of their condition.

Physical training is beneficial to functional status and survival in patients with prolonged mechanical ventilation

BACKGROUND/PURPOSE

Early physical training is necessary for severely deconditioned patients undergoing prolonged mechanical ventilation (PMV), because survivors often experience prolonged recovery. Long-term outcomes after physical training have not been measured; therefore, we investigated outcome during a 1-year period after physical training for the PMV patients.

METHODS

We conducted a prospective randomized control trial in a respiratory care center. Thirty-four patients were randomly assigned to the rehabilitation group (n = 18) and the control group (n = 16). The rehabilitation group participated in supervised physical therapy training for 6 weeks, and continued in an unsupervised maintenance program for 6 more weeks. The functional independence measurement (FIM) was used to assess functional status. Survival status during the year after enrollment, the number of survivors discharged, and the number free from ventilator support were collected. These outcome parameters were assessed at entry, immediately after the 6 weeks physical therapy training period, after 6 weeks unsupervised maintenance exercise program, and 6 months and 12 months after study entry.

RESULTS

The scores of total FIM, motor domain, cognitive domain, and some sub-items, except for the walking/wheelchair sub-item, increased significantly in the rehabilitation group at 6 months postenrollment, but remained unchanged for the control group. The eating, comprehension, expression, and social interaction subscales reached the 7-point complete independence level at 6 months in the rehabilitation group, but not in the control group. The 1-year survival rate for the rehabilitation group was 70%, which was significantly higher than that for the control group (25%), although the proportion of patients discharged and who were ventilator-free in the rehabilitation and control groups did not differ significantly.

CONCLUSION

Six weeks physical therapy training plus 6 weeks unsupervised maintenance exercise enhanced functional levels and increased survival for the PMV patients compared with those with no such intervention. Early physical therapy interventions are needed for the PMV patients in respiratory care centers.

Responsiveness of three instruments to assess self-reported functional status in patients with COPD

The study aimed to compare the responsiveness of three instruments to assess self-reported changes in functional status after exercise training in patients with COPD: Pulmonary Functional Status and Dyspnea Questionnaire -modified version (PFSDQ-M), London Chest Activity of Daily Living (LCADL) and Medical Research Council scale (MRC). Twenty-two patients (11 female, 66[62-71] years, FEV1 42[33-61]%predicted) participated in a 3-month high-intensity exercise program. The three instruments were applied pre- and post-program, as well as assessment of lung function, muscle strength, exercise capacity (6-minute walking test, 6MWT) and quality of life (St. George's Respiratory Questionnaire, SGRQ). SGRQ, 6MWT and quadriceps femoris, biceps and triceps brachialis strength improved significantly after the program (p < 0.05 for all). Training also yielded significant improvement in the LCADL total score and self-care, domestic and leisure domains and in the PFSDQ-M 'change in activities' domain, with no improvement in the MRC (p = 0.11). Calculation of effects sizes also indicated higher responsiveness in the LCADL than the other instruments. There were no significant correlations between changes in the three instruments and changes in lung function, SGRQ or 6MWT. In conclusion, PFSDQ-M's 'change in activity' domain and specially the LCADL (to a higher extent) showed responsiveness to detect changes in functional status after three months of high-intensity exercise training in patients with COPD, whereas the MRC scale did not. In this population, the improvement in functional status was not related with improvement in exercise capacity, lung function or quality of life.

Use of the Functional Independence Measure in people for whom weaning from mechanical ventilation is difficult

BACKGROUND

The Functional Independence Measure (FIM) has been proposed as an outcome measure for people receiving pulmonary rehabilitation after an acute exacerbation of chronic obstructive pulmonary disease. Objective The purpose of this study was to examine the clinical utility of the FIM after a weaning program in people for whom weaning from mechanical ventilation is difficult. Design This was a retrospective observational study.

METHODS

People who had had a tracheostomy, for whom weaning from mechanical ventilation was difficult, and who were participating in a weaning program (WP group) were retrospectively evaluated. People receiving pulmonary rehabilitation after an acute exacerbation of chronic obstructive pulmonary disease (PR group) were included as a validated control group. The scores on the FIM questionnaire and the Medical Research Council dyspnea scores were assessed at admission to and at discharge from the programs.

RESULTS

Admission and discharge data from 56 participants in the WP group and 63 participants in the PR group were compared. At admission, according to the FIM, 5 participants in the WP group (7.7%) were defined as functionally independent, 34 (52.3%) were defined as partially dependent, and 26 (40.0%) were defined as completely dependent. At discharge, the mean FIM global score was significantly improved, from 47.9 (SD=22.8) to 62.6 (SD=30.0). For participants in the WP group, changes in the FIM score were significantly inversely related to the admission Acute Physiology and Chronic Health Evaluation (R=-.286) and Simplified Acute Physiology (R=-.293) scores and directly related to the admission FIM score (R=.355). At admission, 46 participants in the PR group (67.7%) were defined as functionally independent, 19 (27.9%) were defined as partially dependent, and 3 (4.4%) were defined as completely dependent. After pulmonary rehabilitation, the mean FIM global score was significantly improved, from 97.4 (SD=27.5) to 102.5 (SD=25.7). Limitations The study was not randomized and involved a relatively small sample size.

CONCLUSIONS

The FIM can be used as a functional status outcome measure in people for whom weaning from mechanical ventilation is difficult.
