Impact of the chronic disease self-management program (CDSMP) on self-perceived frailty condition: the EU-EFFICHRONIC project.

INTRODUCTION: The Chronic Disease Self-Management Program (CDSMP) improves self-efficacy and health outcomes in people with chronic diseases. In the context of the EFFICHRONIC project, we evaluated the efficacy of CDSMP in relieving frailty, as assessed by the self-administered version of Multidimensional Prognostic Index (SELFY-MPI), identifying also potential predictors of better response over 6-month follow-up.
METHODS: The SELFY-MPI explores mobility, basal and instrumental activities of daily living (Barthel mobility, ADL, IADL), cognition (Test Your Memory-TYM Test), nutrition (Mini Nutritional Assessment-Short Form-MNA-SF), comorbidities, medications, and socio-economic conditions (social-familiar evaluation scale-SFES). Participants were stratified in three groups according to the 6-month change of SELFY-MPI: those who improved after CDSMP (Δ SELFY-MPI < 0), those who remained unchanged (Δ SELFY-MPI = 0), and those who worsened (Δ SELFY-MPI > 0). Multivariable logistic regression was modeled to identify predictors of SELFY-MPI improvement.
RESULTS: Among 270 participants (mean age = 61.45 years, range = 26-93 years; females = 78.1%) a benefit from CDSMP intervention, in terms of decrease in the SELFY-MPI score, was observed in 32.6% of subjects. SELFY-MPI improvement was found in participants with higher number of comorbidities (1-2 chronic diseases: adjusted odd ratio (aOR)=2.38, 95% confidence interval (CI) =1.01, 5.58; ⩾ 3 chronic diseases: aOR = 3.34, 95% CI = 1.25, 8.90 vs no chronic disease), poorer cognitive performance (TYM ⩽ 42: aOR = 2.41, 95% CI = 1.12, 5.19 vs TYM > 42) or higher risk of malnutrition (MNA-SF ⩽ 11: aOR = 6.11, 95% CI = 3.15, 11.83 vs MNA-SF > 11).
CONCLUSION: These findings suggest that the CDSMP intervention contributes to decreasing the self-perceived severity of frailty (SELFY-MPI score) in more vulnerable participants with several chronic diseases and lower cognitive performance and nutritional status.

Introduction

The Chronic Disease Self-Management Program (CDSMP) is an evidence-based program designed to improve the self-management of chronic conditions.[1,2] The CDSMP was developed on the Bandura’s Self-efficacy theory, and can be attended by an heterogenous population with several chronic health and mental conditions, but also their caregivers.[4,5]

Large amount of evidence supported the effectiveness of the CDSMP in improving physical and psychological well-being,[6,7] health-related quality of life, medication utilization, and communication with health professionals. Moreover, healthcare-related cost savings were demonstrated in several studies in terms of reduction in visits to general practitioner, admission to the emergency department and besides lower frequency and shorter duration of hospitalization.[10,11]

Although it has been clearly demonstrated that CDSMP led to better health outcomes, an important issue is identifying whether baseline participants’ characteristics are able to predict better clinical outcomes after attending this intervention. It has been demonstrated how lower self-efficacy and health-related quality of life, and younger age at baseline were correlated with more positive health outcomes after CDSMP. Nevertheless, it seems that no studies focused on the impact of the CDSMP on the self-perceived frailty condition of such vulnerable people.

The EU-funded project EFFICHRONIC (Enhancing health systems sustainability by providing cost-efficiency data based interventions for chronic management in stratified population based on clinical and socio-economic determinants of health) tested the impact of the implementation of the CDSMP on the health systems sustainability in five European countries (France, Italy, Spain, The Netherlands, UK) in terms of the positive return of investment and cost-efficiency.[13,14] In this framework it has been recently developed and validated a self-administered version of the Multidimensional Prognostic Index (SELFY-MPI). This is derived from the Multidimensional Prognostic Index (MPI) a well-validated prognostic tool exploring the multidimensional impairment across multiple areas including physical, cognitive, biological, nutritional, and social domains. The SELFY-MPI might be a useful stratification tool able to easily assess frailty risk condition without being influenced by age.

Therefore, the aim of the present study was to evaluate the usefulness of the CDSMP in improving the SELFY-MPI score over 6-month follow-up and detecting potential predictors of a better response among community-dwelling subjects with chronic diseases and their caregivers.

Methods

Study design and population

The population level recruitment was part of the project “738127/EFFICHRONIC,” a multicentre non-controlled prospective study, which received funding from the European Union’s Health Program (2014–2020). The EFFICHRONIC project was developed and implemented in five European countries (France, Italy, Spain, The Netherlands, United Kingdom) between June 2018 and February 2020, but the present study collected the population recruited in Montpellier (France) and Genoa (Italy) specifically.

The inclusion criteria were: (I) age 18 years or over; (II) presence of at least one chronic condition (defined according to the International Classification of Primary Care—ICPC-2) with at least > 6 months of evolution; (III) informal caregivers who live socially isolated; (IV) absence of acute clinical condition; (V) ability to provide informed consent; (VI) availability to attend a six-weeks course. Subjects were excluded whether: (I) could not commit to a 6-month follow-up regardless of the reason; (II) lived a period of crisis (domestic violence, refugees without a stable environment, eviction, etc.), (III) were homeless or roofless, (IV) were affected by severe mental health problems according to DSM V distorting perception of reality and/or prejudicing the ability to function in a group, (V) had cognitive decline (e.g. Alzheimer’s disease), (VI) had active addictive disorders (drugs, alcohol), (VII) did not have adequate knowledge of the language of the country of residence, and (VIII) were prisoners or subjects who were involuntary incarcerated.

In this post hoc, per-protocol analysis, out of 592 subjects screened in Montpellier and Genoa centers, we included 270 participants (45.6%) who had attended more than half of CDMSP sessions (at least four of six) and had completed the SELFY-MPI at baseline as well as at 6-month follow-up (Supplementary Figure 1).

All participants enrolled read and signed the informed consent form and all their records and personal information were made anonymous. This longitudinal cohort study was conducted according to the World Medical Association’s 2008 Declaration of Helsinki and according to the ethical regulations of each study site. The trial is registered at clinicaltrials.gov (identifier NCT03840447).

Chronic Disease Self-Management Program (CDSMP)

The CDSMP is designed along the self-efficacy theory and allows sharing of skills that are common to a wide variety of chronic conditions such as coping skills, symptoms control, problem solving, confidence building, and decision making. The CDSMP intervention consisted of 6 weekly workshops of 2.5 hours each, led by two leaders (an healthcare professional and a lay-person together) who adhered to a detailed manual. All workshop leaders were trained by Standford-certified CDSMP master trainer and each edition of the program was not modified from the standard CDSMP protocol both in France and in Italy. The intervention was structured as face-to-face small-group meetings attended by about 15 participants. Discussed topics included information on exercise, healthy nutrition, cognitive symptom-management techniques, fatigue-management, dealing with fear, anger, and depression, learn how to control pain and discomfort, communication with others including health professionals, use of medications, action planning, problem solving, and decision making.

Each CDSMP delivery site recruited participants for their workshops in several ways including flyers, brochures, snowball sampling and referrals from health and social local organizations.

To ensure a better adherence to CDSMP intervention, also after center-based visits and during all the 6-month follow-up, each participants received a handout with the workshop topics, homework assignments, and a consultation book.

Self-administered Multidimensional Prognostic Index (SELFY-MPI)

The self-administered Multidimensional Prognostic Index (SELFY-MPI) is a validate, composite tool, stemming from the standard MPI, and thus able to detect frailty condition based on the principles of Comprehensive Geriatric Assessment (CGA). It is structured on information derived by eight domains each one assessed through the following self-administered scales :

(a) Functional status evaluated by the Barthel Activities of Daily Living (ADL) scale, in its self-assessed version. This scale measures the level of dependence/independence in six daily personal care activities: feeding, bathing, personal hygiene, dressing, fecal and urinary continence and toilet use.

(b) Mobility assessed through the Barthel mobility sub-scale, which assess the following three abilities: going up and down the stairs, walking and getting in and out of bed/chair. This scale may be self-administered.

(c) Independence in the instrumental activities of daily living (IADL) measured through the self-administered version of Lawton’s IADL scale that investigates the independence in the following eight activities: telephone use, grocery shopping, meal preparation, housekeeping, laundry, travel, medication and handling finances.

(d) Cognitive status assessed through the self-administered cognitive screening test Your Memory (TYM) that is a 10-task performance test exploring several cognitive domains such as orientation, ability to copy a sentence, semantic knowledge, calculation, verbal fluency, similarities, naming, visuo-spatial abilities and recall of a previously copied sentence. Its score ranges between 0 and 50, with higher scores denoting a better cognitive performance.

(e) Nutritional status evaluated through the self-administered version of the Mini Nutritional Assessment Short-Form (MNA-SF), that contains information regarding the weight loss, the decline in food intake, mobility, recent psychological stress, neuropsychological problems and anthropometric measure (body mass index).

(f) Number of drugs taken regularly cross-checked with the comorbidities.

(g) Comorbidity assessed by investigating the number of pathologies, among the first 13 categories of the Cumulative Illness Rating Scale (CIRS) for which a drug therapy is prescribed and assumed regularly.

(h) Social and economic situation evaluated through an adapted version of Gijón social-familial evaluation scale (SFES). This scale explores socio-economic variables such as: participant’s household composition, the net monthly household income, housing situation, participant’s social relationships and social support. The maximum score of the SFES scale is 25 points; scores > 15 indicate social problems and scores between 10 and 14 a potential social risk.

For each domain, a tripartite hierarchy was adopted based on conventional cut-off points : a score of 0 indicates no problems, 0.5 minor problems and 1.0 major problems (Table 1). The sum of these eight domains must be divided by 8 in order to obtain the SELFY-MPI score which ranges from 0 (no multidimensional impairment) to 1 (maximum multidimensional impairment).

Statistical analysis

Descriptive statistics were expressed as mean and standard deviation (SD) or median and interquartile range (IQR) for continuous variables and as absolute and relative frequencies (percentages) for categorical variables. Differences between SELFY-MPI at 6-month and SELFY-MPI at baseline (ΔSELFY-MPI) were calculated for each patient. Thus, we stratified participants in three groups according the ΔSELFY-MPI: those who improved (ΔSELFY-MPI < 0), those who remained unchanged (ΔSELFY-MPI = 0), and those who worsened (ΔSELFY-MPI > 0). To test difference between subjects with different number of comorbidities (i.e. 0 -recruited among accompanying caregivers of included patients with chronic diseases-, 1–2 chronic diseases, or 3 and more) or with different ΔSELFY-MPI, we used one-way ANOVA for continuous variables and chi-square test for categorical variables. Bonferroni correction was adopted to account for multiple comparisons. To visually compare changes in each different SELFY-MPI domain, we calculated the z-scores of each scale change over time. Multivariable logistic regression was modeled to identify potential predictors of SELFY-MPI improvement among: age > 65 years, gender, number of comorbidities (i.e. 0, 1–2, ⩾ 3), and dichotomized variables, based on well-established cut-off, for impaired mobility (Barthel mobility > 0), poor social condition (SFES ⩾ 10), cognitive disorders (TYM ⩽ 42) and higher risk of malnutrition (MNA-SF ⩽ 11). We further adjusted the results for clinical site and full attendance to CDSMP and SELFY-MPI at baseline. All analyses were conducted using SPSS software version 26.0 (IBM, Armonk, New York). Two-tailed probabilities were reported and a p-value of 0.05 was used to define nominal statistical significance.

Results

Overall, 270 subjects from Italian and French cohort (mean age 61.45 ± 13.55 years, range 26–93 years; females: 78.1%) attended more than half of the CDSMP (60.7% followed all the sessions) and completed the SELFY-MPI both at baseline and at 6-month follow-up. We included 49 caregivers without chronic diseases, 166 subjects with one or two chronic diseases and 55 with three or more chronic diseases. Mean SELFY-MPI score at baseline was 0.17 (SD: 0.12).

Participants who did not perform SELFY-MPI assessment at 6-month follow-up, due to COVID-19 restrictions, had similar age (mean age: 61.2 years old) and gender (female: 75.2%) distribution compared to subjects included in the analysis, but were more compromised at SELFY-MPI assessment performed at baseline (0.24).

Table 2 showed baseline characteristics of participants based on number of comorbidities. Subjects with chronic diseases were significantly older than healthy participants and, as we expected, reported a progressive increase of total medications and of SELFY-MPI score as the number of disease increases. Those subjects with three or more chronic conditions had also significantly higher body mass index (BMI) and lower rate of independency in IADL compared to healthy participants.

At 6-month follow-up, mean SELFY-MPI did not significantly change compared to baseline (0.17, SD: 0.13). However, stratifying subjects based on ΔSELFY-MPI, we found a benefit from CDSMP intervention, in terms of decrease in the SELFY-MPI score at 6 months, in the 32.6% of participants, while 28.9% worsened and 38.5% remained stable. Comparing subjects who experienced an improvement of SELFY-MPI with those who worsened or remained unchanged, we found that the formers were on average more cognitively impaired, malnourished and with more medications at baseline (Table 3). Subjects with higher number of comorbidities reported higher proportion of improvement in SELFY-MPI at 6 months (Figure 1).

Independently of potential confounders including age, gender, CDSMP attendance and SELFY-MPI score at baseline, higher number of comorbidities (1–2 chronic diseases: adjusted odd ratio (aOR)= 2.38, 95% confidence interval (CI)= 1.01, 5.58; ⩾ 3 chronic diseases: aOR = 3.34, 95% CI = 1.25, 8.90 vs no chronic disease), lower cognitive performance (TYM ⩽ 42: aOR = 2.41, 95% CI = 1.12, 5.19 vs TYM > 42) and poorer nutritional status (MNA-SF ⩽ 11: aOR = 6.11, 95% CI = 3.15, 11.83 vs MNA-SF > 11) predicted an improvement of SELFY-MPI after CDSMP (Table 4).

Discussion

In this cohort of community-dwelling subjects with chronic diseases and their caregivers, we found that, after 6-month CDSMP, the self-perceived multidimensional impairment was reduced compared to the baseline measurement, as assessed by SELFY-MPI, in around one-third of participants. Higher number of comorbidities as well as higher level of cognitive impairment and malnutrition at baseline were independent predictors of greater benefit from CDSMP in terms of SELFY-MPI reduction.

Most consistent outcomes in randomized controlled trials testing CDSMP are improvement in aerobic exercise, management of cognitive symptoms, psychological health, communication with physicians and reduced hospitalizations. To our knowledge, this is the first study assessing the efficacy of CDSMP in reducing self-reported frailty condition based on change of a well-validated tool, the SELFY-MPI that measures impairment across multiple domains (i.e. functional, mobility, cognitive, nutritional, comorbidities, drugs and social conditions). The SELFY-MPI was derived from traditional MPI, performed by health professionals. The MPI proved excellent accuracy in predicting several negative outcomes among community-dwelling older adults with chronic diseases and was also recognized as a useful tool able to track changes in health status and to measure frailty condition through a CGA-based multidimensional approach. Given the strong agreement with the standard MPI, the SELFY-MPI score could be similarly a good indicator of frailty condition.

Here we found that presence of three or more chronic conditions, lower cognitive performance and poorer nutritional status, at baseline, significantly predicted a successful outcome after CDSMP. These findings suggest that people with higher illness burden may benefit more from CDSMP. Indeed, previous evidence from a randomized controlled trial carried out on 629 subjects with chronic diseases, showed that poorer health status and lower confidence in the management of chronic disease were strong predictors of greater benefit on health-related quality of life in patients undergoing CDSMP. Moreover, subjects with higher number of comorbidities (i.e. two or more chronic diseases plus depression) reported higher effectiveness of CDSMP on vitality and quality of life.

Among subjects who reported a reduction of SELFY-MPI after CDSMP, greater benefit in self-perceived multidimensional assessment was observed in terms of reduction of comorbidities and medications, and improvement of cognitive and nutritional status. It is well established that multimorbidity is related to poor cognitive function and accelerated cognitive decline.[28-30] Previous studies demonstrated that CDSMP was able to improve management of cognitive symptoms. Also malnutrition is frequently associated with chronic diseases, probably due to a pro-inflammatory state, typical of chronic conditions that determines anorexia, malabsorption and alteration of metabolism. Some report highlighted that lack of nutritional advices represents a serious complain among multimorbid subjects, thus CDSMP might help to improve adherence to healthy diet lifestyle. Self-perceived reduction of burden of diseases and consequent deprescription could be also important goals of CDMSP and further efforts should be taken to broaden the spectrum of these benefits.

These findings are in our opinion of clinical importance since the availability of a sensitive and reliable global health status indicator, as the SELFY-MPI, would be useful for the management of patients with chronic diseases. In particular, in the framework of a CDSMP, the SELFY-MPI might help to reinforce aspects of the intervention mainly connected to the health domains with the highest degree of impairment (e.g. cognition, malnutrition).

This study has some limitations. First the absence of comparison group did not allow to compare the CDSMP to the standard of care. Second, the enrolled sample was relatively small, therefore we were not able to sub-divide numbers of physical conditions into more levels and explore the role of clusters of chronic diseases (e.g. diabetes and hypertension, diabetes and cancer). Third, we recruited a population of well-functioning community-dwelling subjects, thus further studies are warranted to confirm these results among more frail subjects from different kind of settings. Fourth, the attrition rate was high because of lockdown measures related to COVID-19 pandemic occurring during follow-up. Finally, given the post hoc nature of the analysis, the usefulness of SELFY-MPI in the identification of subjects who best benefit from CDSMP need to be tested in ad hoc-designed studies.

Conclusion

Our findings support the hypothesis that the CDSMP may contribute to the reduction of the self-perceived severity of frailty condition, based on SELFY-MPI score, in particular among more vulnerable subjects with more chronic diseases, lower cognitive performance and poorer nutritional status. Present findings should further encourage policy makers and stakeholders to promote CDSMP for reducing the healthcare burden of chronic diseases.
