ASBHDS Session 2 - Quality of Life, Long Term Conditions and Mental Health Flashcards
What are the reasons for measuring health?
- To have an indication of the need for healthcare.
- To target resources where they are most needed.
- To assess the effectiveness of health interventions.
- To evaluate the quality of health services.
- To use evaluations of effectiveness to get better value for money.
- To monitor patients’ progress
What are commonly used measurements of health?
- Mortality
- Morbidity
- Patient-based outcomes
Outline patient-based outcomes.
- An attempt to assess well-being from the patient’s point of view.
- Examples are: health-related quality of life (HRQoL), health status, functional abilities.
- Patient-reported outcome measures (PROMs) are measures of health that come directly from patients. They work by comparing scores before and after treatment or over longer-periods
What is the use of patient based outcomes?
- Patient base outcomes are used in conditions where the aim is managing rather than curing. Biomedical tests just one part of picture. There is a need to focus on patient’s concerns (patient-centred care). One needs to pay attention to iatrogenic effects of care.
- Patient-based outcomes can:
I. Be used clinically
II. Be used to assess benefits in relation to cost
III. Be used in clinical audit
IV. Be used to measure health status of populations
V. Be used to compare interventions in a clinical trial
VI. Be used as a measure of service quality
Outline Patient-reported outcome measures (PROMs).
- Improve clinical management of patients – informed, shared decision-making
- Domain 2: Enhancing quality of life for people with long-term conditions. Overarching indicator 2: Health-related quality of life for people with long-term conditions.
- Domain 3: Helping people to recover from episodes of ill health or following injury. Improvement area 3.1 Total health gain as assessed by patients for elective procedures (measured using a PROM)
- Challenges:
I. Minimising the time and cost of collection, analysis, and presentation of data
II. Achieving high rates of patient participation
III. Providing appropriate output to different audiences
IV. Avoiding misuse of PROMs
What is Health related quality of life (HRQoL) and what does it depend on?
- ‘Quality of life in clinical medicine represents the functional effect of an illness and its consequent therapy upon a patient, as perceived by the patient.’
- Depends on:
I. Physical function
II. Symptoms
III. Global judgements of health
IV. Psychological well-being
V, Social well-being
VI. Cognitive functioning
VII. Personal constructs
VIII. Satisfaction with care
How does one measure HRQoL using PROM?
- Use of questionnaires known as ‘instruments’ or ‘scales’
- Should fulfil certain criteria:
I. Reliability- is the instrument accurate over time and internally consistent? (if the patient has no change in health, she should get the same score each time on the measure)
II. Validity – does the instrument actually measure what it is intended to measure? (a measure might be accessing only pain, and neglecting social aspects of illness)
What are the two basic groupings for measuring HRQoL using PROM?
- Generic instruments
I. Can be used with any population (incl. healthy people)
II. Generally cover perceptions of overall health
III. Also questions on social, emotional and physical functioning, pain and self-care
- Specific instruments
I. Evaluates a series of health dimensions specific to a disease, site or dimension
II. Types of specific instruments:
A. Disease specific – Asthma Quality of Life Questionnaire, Arthritis Impact Measurement Scale (AIMS)
B. Site specific – Oxford Hip Score, Shoulder Disability Questionnaire
C. Dimension specific – Beck Depression Inventory, McGill Pain Questionnaire
What are some pros and cons of generic instruments?
- Generic instruments – advantages:
I. Can be used for broad range of health problems
II. Can be used if no disease-specific instrument
III. Enable comparisons across treatment groups
IV. Can be used to detect unexpected positive/negative effects of an intervention
V. Can be used to assess health of populations
- Generic instruments – disadvantages:
I. Generic nature means inherently less detailed
II. Loss of relevance – too general?
III. Can be less sensitive to changes that occur as a result of an intervention
V. May be less acceptable to patients
What are some examples of generic measures?
- The Short-Form 36-item questionnaire (SF-36)
- The EuroQol EQ-5D
Outline the SF-36.
- Contains 36 items which can also be grouped into 8 dimensions:
I. Physical functioning
II. Social functioning
III. Role functioning (physical)
IV. Role functioning (emotiona)
V. Bodily pain
VI. Vitality
VII. General health
VIII. Mental health
- Responses are scored. Scores for items within each dimension are added together. This score is transformed to give each respondent’s score for each dimension (0-100).
Outline EuroQol EQ-5D.
- Generates a single index value for health status on which full health is assigned a value of 1 and death a value of 0.
- It is particularly suitable for use in economic evaluations.
- It has 5 deimensions
I. Mobility
II. Self-care
III. Usual activities
IV. Pain/Discomfort
V. Anxiety/Depression
- It has 3 levels for each dimension
I. No problems
II. Some/moderate problems
III. Extreme problems
Outline the pros and cons of Specific instrumens.
- Specific instruments – Advantages:
I. Very relevant content
II. Sensitive to change
III. Acceptable to patient
- Specific instruments – Disadvantages:
I. Can’t use them with people who don’t have the disease
II. Comparison is limited
III. May not detect unexpected effects
Discuss anxiety due to another medical condition.
- In general, anxiety disorders are normal reactions to stress that has become excessive. The anxiety is shown as significant and possibly intense dread or uneasiness. Anxiety may take the form of panic attacks, obsessive-compulsive behavior or generalised anxiety.
- It is a response to a threat
I. Threats to identity/well-being
II. Threatening events (sugery, treatment, test results, uncertainty)
- Likely to occur at various stages in illness – e.g. diagnosis, awaiting test results, discharge from hospital, illness progression, making lifestyle changes
Discuss Depressive disorder due to another medical condition
- Response to loss, failure or helplessness
I. Loss of health/physical capacity
II. Loss of identity/social status
III. Reaction to symptoms, negative experiences of illness
IV. Physiological changes (e.g. MS)
V. Medication side effects
- Tends to be long term
- Co-morbid depression can:
I. Exacerbate the distress associated with physical health problems; adversely affect illness outcomes (including via reduced adherence to treatment) (NICE 2010)
II. Increase risk of mortality E.g. 1 in 10 with post-stroke depression have suicidal thoughts
