50
Q

What did the Calman-Hine report of 1995 do?

A

Examined cancer services in the UK, and proposed a restructuring of cancer services to
achieve a more equitable level of access to high levels of expertise throughout the country.

51
Q

What were the conclusions of the Calman-Hine report

A
  • all patients shld have access to a uniformly high quality of care (justice)
  • public + professional education about the early symptoms of cancer
  • pts, families + carers shld be given clear information about all the treatment options + outcomes (autonomy)
  • psychosocial needs of cancer sufferers and their carers shld be recognised
  • development of cancer care services shld be patient centred (beneficence)
  • primary care shld be central to cancer care
52
Q

What were the Calman-Hine solutions?

A

There should be 3 levels of care:

  • Primary care
  • Cancer units => in general hospitals for: treating common cancers, running diagnostic procedures, non-complex chemo + common surgeries
  • Cancer centres => treating rare cancers, radiotherapy + complex chemo

***key to managing patients would be MDT

53
Q

Which cancer care policy set out the first ever comprehensive plan to tackle cancer disease?

A

NHS cancer plan - 2000

54
Q

Aims of NHS cancer plan 2000

A
  • To save more lives (i.e reduce burden of disease)
  • To ensure people w cancer get the right professional support + care as well as the best treatments (beneficence)
  • To tackle the inequalities in health that mean unskilled workers are twice as likely to die from cancer as professionals
  • To build for the future through investment in the cancer workforce, through strong research and through preparation for the genetics revolution, so that the NHS never falls behind in cancer care again
55
Q

Role of cancer networks in NHS cancer plan 2000

A

Cancer networks -> organisation model of cancer services to implement plan:
- to bring together health service commissioners and providers, the voluntary sector, and local authorities

  • Each network will typically serve a population of around 1-2 million people
56
Q

Role of National Awareness and Early Diagnosis Initiative in cancer care

A
  • raise public awareness of early signs+symptoms of cancer

- encourage ppl to seek help sooner

57
Q

6 key areas for action highlighted by the Cancer Reform Strategy 2007

A
  1. Prevention - reduce risk factors e.g. smoking, obesity
  2. Diagnosing cancer earlier - screening, public awareness
  3. Living with cancer and beyond
  4. Ensuring better treatment
  5. Reducing cancer inequalities
  6. Delivering care in the most appropriate setting
58
Q

What were the main outcomes from ‘Improving outcomes: A strategy for cancer (2011)’?

A

 Prevention and early diagnosis - Focus on lifestyle factors, screening, diagnostic tests

 Quality of life and patient experience - Patient experience surveys, more 1-1 support roles, risk stratified pathway of care, following assessment and care planning

 Better treatments - Cancer drugs fund, reducing variation in radiotherapy,
reaffirmed MDTs and national audits

 Reducing inequalities

59
Q

Why is cancer survival improving in the UK?

A
  • newer treatments

- faster diagnoses

60
Q

Inequalities experienced among cancer patients:

A

 White cancer patients report a more positive experience than other ethnic groups

 Younger people are the least positive about their experience, particularly around understanding completely what was wrong with them

 Men are generally more positive about their care than women, particularly around staff and staff working together

 Non-heterosexual patients reported less positive experience, especially in relation to communication and being treated with respect and dignity

 People with rarer forms of cancer in general reported a poorer experience of their treatment and care than people with more common forms of cancer

61
Q

How might doctors deal with angry patients?

A
  • Recognise/acknowledge
  • Remain calm
  • Do not dismiss it
