Clinimetrics in Post-Polio

 ICF

 The International Classification of Functioning, Disability

and Health (ICF) 2001

 developed by the World Health Organization’s (WHO),

provides a unified language and framework for the description of functioning and disability in polio survivors. Assessment of functioning and disability is important for diagnostic purposes and with repeated assessments, can assist in monitoring disease progression and provide prognostic information.

SLIDE 15

Clinimetrics in Post-Polio

 ICF International Classification of Functioning,

Disability and Health

Assessments can also be used for evaluating the efficacy of interventions both for each individual polio survivor but also in the context of clinical

  • trials. According to ICF participation is defined by

involvement in a life situation. Environmental factors have an impact on all components of functioning/disability and vice versa.

 ICF Body structure in PPS: pain

In another study by Werhagen and Borg (2013), pain was present in 68% of PPS patients. Pain had significant impact on Quality of Life, as measured by SF-36. Although patients have a high mean VAS score the pain only affects quality of life for Vitality and General Health, but not for other physical and mental domains.

Participation in Post-Polio

 DEFINITIONS of ICF COMPONENTS  Participation is involvement in a life situation.  Activity limitations are difficulties an individual

may have in executing activities.

 Participation restrictions are problems an

individual may experience in involvement in life situations.

 Environmental factors make up the physical,

social and attitudinal environment in which people live and conduct their lives.

slide-38
SLIDE 38

Disability and participation

 Disability and participation  The social model of disability sees the issue of

"disability" as a socially created problem and a matter of the full integration of individuals into

  • society. In this model, disability is not an

attribute of an individual, but rather a complex collection of conditions, many of which are created by the social environment.

slide-39
SLIDE 39

Participation in Post-Polio

 ICF COMPONENT: Participation

 It is difficult to distinguish between "Activities"

and "Participation" on the basis of the domains in the Activities and Participation component.

 Similarly, differentiating between “individual”

and “societal” perspectives on the basis of domains has not been possible given international variation and differences in the approaches of professionals and theoretical frameworks.

slide-40
SLIDE 40

Participation in Post-Polio

 ICF COMPONENT: Participation

 How to distinguish between "Activities" and

"Participation”?

 There are four possible ways of doing so:  (a) to designate some domains as activities and others as

participation, not allowing any overlap;

 (b) same as (a) above, but allowing partial overlap;  (c) to designate all detailed domains as activities and the

broad category headings as participation;

 (d) to use all domains as both activities and participation.

slide-41
SLIDE 41

Participation in Post-Polio

 ICF COMPONENT: Contextual Factors

 Contextual Factors represent the complete

background of an individual’s life and living. They include two components: Environmental Factors and Personal Factors – which may have an impact on the individual with a health condition and that individual’s health and health-related states.

slide-42
SLIDE 42

Participation in Post-Polio

 ICF COMPONENT: Contextual Factors

 Environmental factors make up the physical,

social and attitudinal environment in which people live and conduct their lives. These factors are external to individuals and can have a positive or negative influence on the individual’s

 performance as a member of society, on the

individual’s capacity to execute actions or tasks,

  • r on the individual’s body function or structure.
slide-43
SLIDE 43

Participation in Post-Polio

 ICF COMPONENT: Environmental factors

 Environmental factors are organized in the

classification to focus on two different levels:

 (a) Individual – in the immediate environment of

the individual, including settings such as home, workplace and school. Included at this level are the physical and material features of the environment that an individual comes face to face with, as well as direct contact with others such as family, acquaintances, peers and strangers.

slide-44
SLIDE 44

Participation in Post-Polio

 ICF COMPONENT: Environmental factors

 Environmental factors are organized in the

classification to focus on two different levels:

 (b) Societal – formal and informal social structures,

services and overarching approaches or systems in the community or society that have an impact on individuals. This level includes organizations and services related to the work environment, community activities, government agencies, communication and transportation services, and informal social networks as well as laws, regulations, formal and informal rules, attitudes and ideologies.

slide-45
SLIDE 45

Participation in Post-Polio

 ICF COMPONENT: Environmental factors  Environmental factors interact with the components of

Body Functions and Structures and Activities and

  • Participation. Disability is characterized as the outcome
  • r result of a complex relationship between an

individual’s health condition and personal factors, and of the external factors that represent the circumstances in which the individual lives. Because of this relationship, different environments may have a very different impact

  • n the same individual with a given health condition. An

environment with barriers, or without facilitators, will restrict the individual’s performance; other environments that are more facilitating may increase that performance.

PARTICIPATION

 How to assess the participation?

 Impact on Participation and Autonomy

In 1999, Mieke Cardol from Research Institute of Public Health NIVEL in Utrecht (Netherlands Institute for Health Services Research) and colleagues published a questionnaire Impact on Participation and Autonomy, shortly named as IPA. This questionnaire passed then the cultural adaptation and validation for English (Paul Kersten from Southhampton), Swedish (Maria Larsen-Lund from Umea), German (Daniel Senn from Wettingen, Switzerland) and Italian (Franco Franchignoni from Verona). The questionnaire is constantly updated and available on the Internet (http://www.nivel.eu). The authors call for sending them any articles written on this topic.

slide-54
SLIDE 54

PARTICIPATION

 Impact on Participation and Autonomy

The questionnaire consists of 32 questions included in the five sub- scales: Autonomy indoors (independence in the apartment - 7 questions), Family roles (the role of the family -7), Autonomy outdoors (independence outside the home - 5), Social life and relationships (social life and interpersonal relationships -7) and work and education (work and study - 6). The last question is general and applies to the question of how a respondent evaluates their chances of living a life in accordance with their expectations (My chances of living life the way I want to are: very good, good, fair, poor, very poor). In response to most of the questions respondents have 5 opportunities, in some cases these are 3 possibilities. The questionnaire takes about 20 minutes to fill in.

PARTICIPATION in late Polio

 Lund and Lexel investigated how 160 persons with late effects of

polio perceive their participation. All subjects answered the Swedish version of the Impact on Participation and Autonomy Questionnaire. In results: A majority of the respondents perceived their participation as sufficient in most activities and 65% of the respondents perceived no severe problems with participation. The remaining 35% perceived 1-6 severe problems with participation. All 5 domains of participation were positively correlated with the 9 items for problem experience. Most restrictions in participation were reported in the domains of Family role, Autonomy outdoors, and Work and education. Insufficient instrumental support was most strongly associated with the perception of severe problems with participation. Lund ML, Lexell J.

PARTICIPATION in PPS

 ICF COMPONENT: PARTICIPATION

In a cross-sectional survey of 336 persons with polio and PPS in UK, in average age of 54 years Atwal et al. found that polio survivors valued social occupations and participation in family life. This research has also shown that healthcare professionals still do not understand polio and PPS and this lack of understanding influences their clients' quality

  • f life. Finances and accessibility of environments also influence

participation in chosen occupations. Rehabilitation programmes for people with polio and PPS need to be targeted towards maintaining and improving accessible environments and participation in chosen

  • ccupations.

PARTICIPATION in PPS

 Jung et al. investigated HRQOL in 364 Swedish patients

with PPS. QOL was significantly lower in PPS patients for all eight subdomains and the two main scores (physical and mental) when compared with the controls. Male patients had a significantly higher QOL than female patients for all subdomains and also for mental compound score and physical compound score. There was a decrease in QOL in the physical domains and an increase in vitality with age. PPS decreases HRQOL in both sexes, more in female patients. QOL for physical domains decreases whereas vitality increases with age.

PARTICIPATION in PPS

 Atwal et al. investigated 51 PPS persons from two

regions in England. Their research found that polio survivors used terms used to describe quality of life which could be associated with that of happiness. This research has identified resolvable factors that influence quality of life namely inaccessible environments, attitudes of health-care professionals and societal

  • attitudes. Polio survivors have tried alternative therapies,

chiefly acupuncture and massage, and found them to be effective in enhancing their quality of life.

PARTICIPATION in PPS

 Ten Katen et al. made a qualitative cross-sectional interview study

with 17 subjects with PPS, 12 women and 5 men, mean age 49 years. Thirteen out of 17 subjects rated their work ability six or higher on a scale from 0 to 10. Most subjects worked in an administrative, educational or managerial function. Five subjects stopped working, four worked between 0 and 20 h/week and eight worked between 20 and 40 h/week. Factors conducive to working were physical adaptations in the workplace, accessibility of the workplace and high decision latitude. Barriers to full work ability in PPS patients were high physical job demands, low social support and the symptoms of PPS, especially fatigue and pain.
