What is the difference between alternative and complementary medicine?

Now increasingly common to combine with traditional medicine - hence complimentary rather than alternative

Some have more relationship to conventional methods than other:
- osteopathy, chiropractors (regulated)

Q

What is aromatherapy?

A

Controlled use of essential oils which have therapeutic properties

Q

What is acupuncture?

A

Stimulation of special points on the body - usually by insertion of fine needles
Workings of the human body are controlled by a vital force or energy called “Qi”
The acupuncture points are located along the meridians and provide means of altering the flow of Qi
Acupuncture points correspond to physiological and anatomical features - e.g. Peripheral nerve junctions
Trigger points and referred pain e.g. Tender areas in neck and shoulder muscles which relate to various patterns of headache

Q

What did the systematic review on acupuncture for migraine discover?

A

22 trials with 4419 participants
Variety of comparisons e.g. ‘Sham’ acupuncture and prophylactic drug treatment
Acupuncture was at least as effective or more effective than the prophylactic drug treatment - with fewer adverse effects
True acupuncture v.s. ‘Sham’ acupuncture results were difficult to interpret
The conclusion was that acupuncture should be considered as a treatment option

A

13 trials with 2,362 patients
8 trials included in a meta-analysis
Range of controls used: true sham and superficial acupuncture, TENS, current drug, education group

Acupuncture also superior to no additional intervention

Q

What are some of the challenges in conducting trials?

A

Resources - who will fund? (Not big pharmaceuticals)
Trial of single intervention may not reflect reality - the whole “ethos”/ engaging with patients etc. Whole package
Multifaceted intervention trial very complex
Agreement to randomisation
Finding placebos/shams is challenging
Difficult to make double-blind

16
Q

Are complementary therapies an appropriate use of resources?

A

Don’t have evidence base to support them - e.g. If money spent on aromatherapy for cancer patients will have less for chemotherapy
What kind of value should be placed on improving the patient’s overall experience of treatment - e.g. Think about the woman who said that aromatherapy really helped her mind set in chemotherapy

17
Q

Should NICE evaluate complementary therapies?

A

Arguments for:

  • high public interest
  • half GPs provide access
  • address inequalities in access/opportunity
  • should apply same standards
  • stimulates more/higher quality research

Against:

  • money in NHS limited
  • NICE has higher priorities
  • poor quality evidence
18
Q

Is evidence based medicine relevant to complementary medicine?

A

Issue of assessing effectiveness in ways consistent with EBM principles
Is EBM relevant and applicable to complimentary medicine?
Whose evidence counts?
Practitioners tend to fall back on evidence based on tradition and experience rather than RCT evidence etc.
Argument that the healing potential of these therapies cant be reduced to an RCT/ grasped by western notion of rationalism
Questioning validity of EBM - when the therapies have been around for 2000 years - surely it must be efficacious and of some value otherwise why do people want it

19
Q

What is the relevance of complementary therapies to doctors?

A

May be able or asked to provide some access to complimentary therapies
Different patients will have different beliefs/approaches
Unlikely to be one universal answer
Need to be aware of the range of therapies available and why patients use them
