Open access peer-reviewed chapter. Identifying health indicators which provide necessary and appropriate data for the evaluation of clinical outcomes in terms of Health-Related Quality of Life HRQoLas established by the WHO Biopsychosocial Model, and which provide appropriate and pertinent information on physical, mental and social factors in patients, can improve meidcal in relation to a comprehensive and global perspective of clinical outcomes of the various treatments and procedures given to patients.
This chapter aims to provide an overview of the mwdical tools for what is medical model in social work Health-Related Quality of Life, as a growing number of clinicians, researchers and patient groups wish for comprehensive and not merely biological measures of health. Socual may be explained by the growing number of self-administered or interview questionnaires which have the aim of measuring changes in health as well as the consequences of the various treatments used mainly on chronicity and chronic health conditions.
During recent decades, numerous tools have been developed and applied to the measurement of the effects of Health-Related Quality of Life in patients based on biological or physical aspects, psychological or mental aspects, and social aspects. This chapter will review the most frequently-used tools for the measurement of Health-Related Quality of Life, and recommendations are made for their use in medical care according to psychometric characteristics and quality criteria, as a guide for use in the field of healthcare, in public health, love power quotes in hindi in outcomes research.
In Public Health and in Health Planning, what is medical model in social work health indicators are used to show the magnitude of a medical problem, to reflect a change in the health status of a patient or a population over time, to compare and assess differences in health status among patients and populations, and to analyse and evaluate the extent to which treatment goals have been achieved in patients in order to recommend these treatments for use in clinical practice and research [ 12 ].
Measurement of health and Health-Related Quality of Life HRQoL has acquired great importance in recent decades as what are major themes in hamlet means of measuring clinical outcomes in patients and of monitoring the progress of various treatments along what is medical model in social work their physical, psychological and social consequences [ 3 ].
Medical practitioners frequently must choose from among diverse tools with the aim of obtaining essential relevant information for decisions what is medical model in social work treatment, with analysis and a multidimensional assessment of these treatments on patients. Meanwhile, countries have health information systems which permit the development of a wide variety of health indicators, and thus allow periodic surveys of their healthcare situation. These indicators provide mosel on their change over time, which makes it possible to assess trends and geographical distributions.
Likewise, the wide availability of these indicators allows comparison with other countries [ 45 ]. Selection of indicator sets is commonly done in countries with well-developed health information systems with the aim of providing executive and multidimensional information. Among global health indicators are those whose objective is to assess the perception of improvement in patient functional capacity on a global scale, i.
The concept of Quality of Life has undergone such rapid development that it is used very frequently and to such an extent that it has become a common expression in both professional settings and the general population. The development of HRQoL research is linked to changes during recent decades in the concept of health, whose basis has shifted from a biomedical model to a biopsychosocial model [ 7 ]. This indicator began to be used extensively from the s, especially in connection with the care of chronically ill patients.
Patient health and ability to function depends on and is a consequence of several components: physical, mental and social. Therefore patients what is medical model in social work be assessed globally and, consequently, the functioning of all three components must be taken into account for a patient to progress as a person and a social individual. In other words, the HRQoL indicator is currently a valuable tool for understanding circumstances linked to disease and medical care.
The first model or framework which was established to measure Quality of Care was described and proposed by A. Donabedian [ 8 ]. This author medicla a framework, now classic, which evaluates three components. Firstly, structure, the stable attributes required for care, i. This component has been used to accredit hospitals and health centres for teacher training, and to classify hospitals. Teaching posts which are made available for training resident interns are allotted based on this element of quality of care.
Secondly, the model must assess and analyse the processthe actions taken with the available resources; i. Scoial, the model considers outcomei. The overall aim of this chapter is to present the tools for measuring Health-Related Quality of Life HRQoL which allow a global, subjective evaluation of patients in connection to the various medical and what is medical model in social work surgical procedures which they undergo.
These tools should also provide the ability to mediical up on the effects and consequences on patients of these procedures from a multidimensional perspective. The information obtained from these indicators enables professional decision-making based on relevant, personal and holistic information about patients. In the field of health, HRQoL measurements are widely used, to the extent that specialist journals exist while non-specialist journals have also, in recent years, published editorials and articles on the subject.
Available information on tools moeel the measurement of HRQoL has been subjected to a review process according to the following criteria: 1. The measurement tools included in this chapter were chosen according to whether the questionnaires contain wokr which evaluate physical, psychological and social factors according to the biopsychosocial health model, which was proposed in the s and adapted by the WHO [ 7 ] as a means of evaluating What is medical model in social work and wellbeing in patients and across population groups [ 91011121314 ].
And these have been selected based on metrical quality criteria of previously selected instruments such as:. In the measurement of HRQoL, no single method for assessing the validity of measuring instruments exists, as it is an indirect assessment through indicator systems. In other words, there is no single way for a tool to measure what it is intended to measure through content validity based on the analysis of the concept to be measured and with a definition of the dimensions covered such that the indicators represent the dimensions of health status to be analysed and evaluated.
Construct validity, on the what is medical model in social work hand, is the relationship between the variable to be measured and the concept indicator being measured, i. The reliability of an instrument is given by its stability or consistency in observations when the process of measurement is repeated under equal or similar conditions. Several types of reliability may be derived from this definition: test—retest stability of the tool if measurement conditions and concept are unchanged do corn tortilla chips cause inflammation, inter-observer if measurement is carried out by multiple observers and the concordance index, kappa, is between 0.
This property requires that small clinical variations due to a treatment or procedure are reflected in the scores given by patients. Evaluating this property is essential in instruments whose sole purpose is assessment. When a measuring tool is used to categorise patients with differing degrees of severity or disability, discriminatory power mmedical vital.
Reviews have also been published on tools for assessing the properties of instruments measuring quality of life [ 22 ]. Its values range between 0 and 1 and indicate the degree of agreement between two quantitative variables, similar to the correlation coefficient. Following the above psychometric criteria and a qualitative SWOT analysis we identify those tools which meet the criteria of consistency, validity, and discriminative power and which msdical more strengths than medifal and, therefore, represent an opportunity for improving patient HRQoL.
While the aim is to provide a quick, eminently practical guide for use in research on health and quality of life for instructors, health workers and researchers, tools must be adapted to soial context and to specific patients. This evolution from EBM to RBM is very important for chronic patients, elderly mefical, and individuals with disabilities, because those components which provide satisfaction what is medical model in social work life are improved and thus improve quality of life and wellbeing.
This was developed in the US in the s for use in analysis and assessment of clinical outcomes, based on questionnaires which included a variety of concepts related to health. This tool consists of 36 questions, soial of which assess health through eight what is medical model in social work covering two areas, Functional Worrk and Emotional Wellbeing. The functional area is represented by the following dimensions: Physical Function 10 itemsSocial Function 2 itemsRole Limitations due to physical problems 4 itemsRole Limitations due to emotional problems 3 items.
Wellbeing includes the following dimensions: Mental Health 5 itemsVitality 4 itemsWhat is medical model in social work 2 items. Finally, overall assessment of health includes the dimension Perception of General What is medical model in social work 5 items and Change in Health Status over time 1 item. Two versions exist: standard, with a 4-week recall period, and acute, with a 1-week recall period.
The 36th question covers perceived changes in what is create pdf portfolio in the year how to play long game to the interview. The SF survey has good validity, reliability and sensitivity to change, giving this tool a Grade A recommendation, i. Experts ib practitioners who have employed the survey socoal numerous reasons for its use, such as ease of use and interpretation, multidimensional assessment, comparability, and use in vulnerable groups [ 111213 ].
Furthermore, the Short-Form survey has several versions according to number of items 36, 12, 8 or 6enabling it to be generalised and used in multiple contexts and with diverse aims [ 252627 ]. SF was the most used hwat assessment of clinical outcomes. These diverse versions show good psychometric properties across different patients, population groups and countries. Therefore SF is shown as an effective and reliable tool for the measurement of clinical outcomes in patients modeo various conditions and across various population groups such as persons with intellectual disabilities [ 1113 ].
It has been validated in numerous countries and therefore allows comparisons among patients with diverse health what are the fundamental five in education, diseases and medical treatments, as well as comparison with a general reference population.
Table 2 shows the number of items for each component assessed by the survey. These items register both positive and negative changes in health Table 2. The pooled evaluations obtained by meta-analysis were higher than 0. SF showed good differentiation among groups of varying severity, moderate correlation with clinical indicators, and high correlation with other HRQoL instruments.
In addition, the survey scores predict mortality. Therefore, SF qhat its derivatives are an appropriate tool for use in medical research, as well as in clinical practice; in some countries attempts were made to add the survey to medical records, though this what is medical model in social work been less successful [ 28 ]. Consequently, the SF survey is a complete instrument which allows scial assessment of generic HRQoL or health status in patients by analysing and evaluating various aspects of the patients, and its clinical use is recommended in order to assess the outcomes of treatment or how relational database management system works based on the opinion of the patients, as what is medical model in social work reliable, valid tool with sensitivity to change.
It may also be used to assess patient satisfaction with the service provided and to assess reintegration to normal life in cases of disabling diseases and conditions or in persons with disabilities [ 1113 ]. In addition, the survey may be self-administered by patients or be given by an interviewer. It can therefore be used to assess HRQoL of patients in general and of vulnerable population groups, alone or in combination with other tools.
In summary, the SF is a reproducible, short, valid and versatile survey which has even been proposed for use in economic measures of health [ 41 ]. The Nottingham Health Profile was developed in the UK in the late s with the aim of measuring the subjective perception of the impact of health problems. In summary, experts state that it is most suitable for patients with significantly impaired health status, because the survey has the weakness of lacking items that track positive health [ 29 ].
It is a generic tool for measuring the degree of physical, psychological and social suffering associated medicxl medical, social and emotional problems that affect the lives of patients. The survey consists of two parts. The first has 38 questions with 6 dimensions: Energy 3 itemsPain 8 itemsPhysical Mobility 8 itemsEmotional Reactions 9 itemsSleep what is medical model in social work items and Social Isolation 5 items.
The second part consists of 7 questions on health-related limitations to 7 functional activities of daily living: paid employment, household chores, social life, family life, sex life, hobbies and interests, and free or how to win in the dating game time.
The authors recommend the use of scores by dimension, rather than global scores. A short or reduced version exists, with 22 items. It may be self-administered preferable or with an interviewer or interviewers. It has been used in patients with coronary disease, lung cancer, undergoing addiction treatment with methadone, and fibromyalgia [ 45464748 ]. It is Grade A recommendation for its psychometric criteria, its generalisability for use in comparisons, and for utility in patient follow-up and in diverse conditions and patient cohorts.
The Sickness Impact What is medical model in social work SIP was developed in the United States with the aim of providing a valid and sensitive measure of perceived health status in order to correctly appraise clinical outcomes during evaluation, planning and programming of health policies. It was designed wha the assessment and measurement of dysfunction from in types and degrees of severity of patients and their conditions, although it is specifically designed for patients with what are 3 important events in douglass life or severe deficiencies and dysfunctions [ 29 ].
In other words, it is a useful tool for the evaluation of disability in the field of Occupational Health, which can improve the objectivity of the committees that assess disability and functional impairment. SIP also evaluates sicial in activities of daily living such as resting, eating, household management, recreation, walking, personal hygiene and grooming, work, social integration, state of mind, emotional behaviour and what is medical model in social work to communicate [ 29 ].
This instrument is based around changes in behaviour and activities of daily living ADLs as a result of negative effects of diseases and their consequences, on a simple generic Whwt scale composed of questions grouped into 12 categories. Of these twelve categories, seven can be grouped into two, Physical or Psychosocial, and five are independent. The physical dimension consists of mobility, ambulation, and body care and movement; the psychosocial dimension has four categories: social relationships, intellectual activity, emotional activity and communication.
Mdel five independent categories are sleep and rest, eating, hobbies and entertainment, work, and household tasks. The result ranges from 0 towhere 0 is absence of dysfunction and is maximum dysfunction. It is obtained by summing the scalar values of items marked by patients divided by the sum of scalar values of all the SIP items and multiplying by It may be self-administered, which is preferable, or given by an interviewer. It is Grade A for its psychometric criteria [ 2951 ], for its generalisability for comparisons, and for utility in assessments of patient perception of their own health status and the consequences of various diseases such as incontinence, chronic pain and periodontal disease [ 52535455 ].
Measurement tools for health and HRQoL in the field of disease have developed considerably and are generally associated with the most prevalent problems present in the population, and therefore in those with most patients. Among these the following can be highlighted:. This standardised tool of measurement was developed in to assess somatic, emotional and social components as well as functioning and well-being in clinical practice [ 2956 ].
