Q

What are the strengths and weaknesses of how mortality data is collected?

A

Strengths:
• Complete coverage in UK
• Important information on health of population

Weaknesses:
• Inaccuracies (diagnostic uncertainty, coding issues, variable quality)
• Ethnicity not collected
• Derivation of social status (post-humous inflammation of status)

19
Q

How are population estimates calculated?

A

Census baseline + births – deaths +/- migration

20
Q

What are the strengths and weaknesses of population estimates?

A

Strengths: up to date; more accurate than population projections
Weaknesses: less reliable the further away from the census; poor migration information; cannot use for predictions

21
Q

What are population projections?

A

Forecast about the future based on assumptions about mortality, fertility and migration.

22
Q

What are the strengths and weaknesses of population projections?

A

Strengths: used for long term planning
Weaknesses: less accurate the further ahead you are projecting; unforeseen changes

23
Q

What is the ageing population phenomena?

A

Population projection between 2016 and 2041 shows that there will be a larger older population by 2041 as life expectancy increases and the ‘baby boomer’ generation reach their 70s – impact on health service due to increased cost of care for elderly, need for chronic disease management and increased mental health issues (e.g. dementia)

24
Q

What is the purpose of population pyramids?

A

Allow for resource planning and comparison of different groups across time

25
Q

What is the purpose of the Cancer Registration System?

A

Monitors cancer rates, evaluates screening and treatment efficacy and aiding research

26
Q

What are the strengths and weaknesses of the Cancer Registration System?

A

Strengths: detailed, up-to-date, record linkage to cancer deaths (through ONS)
Weaknesses: confidentiality can cause access difficulties, expensive

27
Q

What is the purpose of Hospital Episode Statistics?

A

Monitors admissions, outpatients and ED visits in England incl. personal, clinical, geographical and administrative data
Monitors trends in hospital activity, supports service planning and fair access to healthcare
Uses ICD-10 (for conditions treated or investigated) and OPCS-4 (for surgery) as clinical classification

28
Q

What are the strengths and weaknesses of Hospital Episode Statistics?

A

Strengths: complete, accurate and representative
Weaknesses: accessibility

29
Q

What is the purpose of the Quality Outcomes Framework?

A

Points awarded for clinical areas (e.g. management of chronic conditions), public health (e.g. prevention) and additional services (e.g. screening) with a higher income awarded to GPs with higher QoF scores

30
Q

What are the strengths and weaknesses of Quality Outcomes Framework?

A

Strengths: completeness, improves record keeping, representative, updated annually
Weaknesses: unclear whether it actually improves clinical outcomes; no age/ sex breakdown

31
Q

What is the purpose of notification of infectious diseases?

A

31 notifiable diseases with doctor responsible for notifying local health protection team when disease is suspected. Laboratories notify Public Health England when notifiable organism is identified. Used to prevent further infection, identify outbreaks and monitor trends.

32
Q

What are the strengths and weaknesses of notifying for infectious diseases?

A

Strengths: timeliness (weekly reporting); representativeness
Weaknesses: variable completeness for some diseases (e.g. food poisoning can sometimes be treated at home); reporting of suspected cases means accuracy is questionable (e.g. suspected but never diagnosed)

33
Q

What is the CARTA framework for assessing quality of health information?

A 
Completeness 
Accuracy 
Representativeness 
Timeliness
Accessibility
34
Q

Define incidence

A

Rate at which new events occur in a population, over a given time period. Expressed as per n people per time period or per n person-years (person-years = no. of people x no. of years)

35
Q

How do you calculate incidence rate?

A

[no. of new cases/ (no. of people x years observed)] x 1000 (or however many person years the question asks for)

36
Q

Define prevalence

A

A measure of how common a disease is, expressed as a percentage or number per n people

37
Q

How is prevalence calculated?

A

P = (no. of people with disease/ total no. of people) x 100 (for %)

38
Q

What are the 3 types of prevalence?

A

Point prevalence = prevalence at a given point in time
Period prevalence = prevalence within a given time period
Lifetime prevalence

39
Q

What are the 4 factors affecting prevalence?

A

Incidence
Recovery rate
Migration (transfer)
Morbidity (death rate)

40
Q

How are confidence intervals calculated?

A

Upper bound = prevalence + (1.96 x SE)

Lower bound = prevalence – (1.96 x SE)

41
Q

What are confidence intervals used for?

A

Can be used to determine statistical significance between 2 groups – if range crosses 1 then null hypothesis must be accepted
The larger the sample size, the narrower the confidence intervals = good!

42
Q

What is the concept of person-centred care?

A

Concept of person-centred care is a whole person approach designed to put the person’s needs and preferences, as they define them, first.

43
Q

What are the key principles of person-centred care?

A

Care is personalised, coordinated, enabling and that person is treated with dignity, compassion and respect

44
Q

What is the importance of using person-centred care in practice?

A

Positive outcome for patients
Increased patient satisfaction
Less ED visits and more concordance to treatment
Social and political drivers
