Healing and the Patient

The greatest mistake physicians make is that they attempt to cure the body without attempting to cure the mind; yet the mind and body are one and should not be treated separately.

Plato

slide4

Religion

  • The organization of the collective spiritual experiences of a group of people into a system of beliefs and practices
  • The service and worship of God or the supernatural
slide5

Spirituality

  • Broader concept of religion that is primarily dynamic, personal and experiential
  • Features include quest for meaning and purpose, transcendence, connectedness and values
slide6
A solemn and humble request to God, or to an object of worship

A supplication, petition, or thanksgiving, usually expressed in words (and based on faith)

Prayer

slide7

Faith

  • Belief and trust in and loyalty to God
  • Belief in the traditional doctrines of a religion
  • Firm belief in something for which there is no proof
slide8

Science

  • The state of knowing, as distinguished from ignorance or misunderstanding (based on evidence and proof)
  • Knowledge covering general truths or the operation of general laws especially as obtained and tested through the scientific method
slide9

Medicine

  • The science and art dealing with the maintenance of health and the prevention, alleviation, or cure of disease
  • Involves the systematic observation and classification of facts related to the causes, prevention, and treatment of disease

Evidence-Based Medicine

  • The practice of medicine based on the scientific evidence or data revealed during studies using specific outcome measures to test specific therapies
  • Making recommendations for treatment based on proven therapies – usually based on randomized, controlled trials
slide11

Can or should we study prayer?

  • What are the outcomes of prayer?
  • What ‘dose’ of prayer do we use and how do we test it?
  • How do we define healing?
  • Is studying prayer and religion consistent with our faith?

Jesus said to him . . .

“It is written again. Thou shalt not test the Lord thy God.”

Matthew 4:7

slide12

Are there data on prayer in medicine?

  • Medline search 1966-2005
  • Prayer, religion, faith, spirituality, health, cancer
  • Over 1,000 articles
  • Three major themes . . .

(1)Associations between religion, spirituality and health

(2) Religion, spirituality and cancer

(3) Studies of intercessory prayer

Religion, Spirituality and Medicine

Mueller PS. Mayo Clinic Proc 2001;76:1225-35.

Studies Do Show

Studies Do Not Show

  • Most have a spiritual life
  • Most want their spiritual needs assessed and addressed
  • Relationship between religion and better health outcomes
  • Spirituality appears to enhance coping and recovery
  • Religious people don’t get sick
  • Illness is due to a lack of religious faith
  • Spirituality is the most important factor in health
  • Doctors should prescribe religious activities
slide19

Religion, Spirituality and Cancer

Stefanek M, et al. Psycho-Oncology 2005;14:450-63.

  • 8 studies found no significant relation of religion and spirituality with morbidity or mortality
  • Numerous studies show that religion and spirituality are important in coping, adjustment and QOL
  • Importance of spirituality in caregivers as well
  • Prayer as a coping strategy – help find comfort, decrease anxiety, facilitate hope and adjustment to illness
slide20

Use of Prayer among Cancer Patients

Taylor EJ. Holist Nurs Pract 2002;16:46-60.

  • 30 adults of various religions
  • Differences in . . .
      • definition of prayer 4. relation to illness
      • how to pray 5. expectations
      • for what to pray 6. how prayer made them feel
  • “I struggle with praying for my own healing. Instead, I pray to be able to live this experience fully . . . And that it be used someway for God’s purpose.”
slide21

Scientific Research on Spirituality

National Institute for Health Care Research, 1997

  • Evaluated the scientific evidence for an association between spirituality and religious practices and health
  • Concluded that spirituality/religious involvement has been shown to be consistently related to positive health outcomes across a variety of health domains
slide22

Research on Religion & Spirituality

National Center for Complimentary and Alternative Medicine

$2.2 million on studies of distant healing and intercessory prayer since 2000

francis galton 1883

It is asserted by some, that men possess the faculty of obtaining results over which they have little or no direct personal control, by means of devout earnest prayer, while others doubt the truth of that assertion. The question regards a matter of fact that has to be determined by observation and not by authority: and it is one that appears to be a very suitable topic for statistical inquiry . . . Are prayers answered or are they not? . . . Do sick persons who are prayed for recover, on the average, more rapidly than others?

Francis Galton, 1883

slide25

Studies of Intercessory Prayer

  • 13 studies identified from 1965-2005 with following criteria:

(1) random assignment of study patients

      • (2) placebo, sham or otherwise blinded or adequate control
      • (3) publication in a peer-reviewed journal
      • (4) clinical investigation of humans
  • No standardization of prayers or intercessors among various trials
  • Heterogeneous diseases and outcome variables
slide26

Intercessory Prayer – The Results

  • 6/13 showed a benefit in primary outcomes
  • 9/13 showed some benefit in some secondary outcomes or showed trends in improvement in health or coping
  • One study suggested that patients who believed the problem could be solved (i.e., had faith) had reduced levels of concern
  • One study identified an effect of retroactive prayer
slide27

Comments on Studying Prayer and Religion

  • Numerous methodological problems
  • Studies suggest that God must respond positively to prayers based on what outcome is chosen; but prayer is more than receiving what is requested, and we aren’t sure how God answers our prayers
  • If distant prayer studies can make the results of prayer consistent, predictable, and replicable, then faith has become a science
  • There is no scientific or theoretical way to answer questions about prayer and religion. These are personal relationships with God and are answered only by moral, theological, philosophical or spiritual methods that go beyond mechanisms of causality.
slide28

Comments on Studying Prayer and Religion

An attempt at scientific proof of the existence of God is an effort . . .

“to create a situation in which God must show Himself and perform a miracle – something that God may do only rarely. Even more rarely does He perform on demand. If God feels the need to give us a sign – He tends to choose the time, place, and form; not us. Simply put, I am sure that such tests are hideously arrogant at best and certainly blasphemous.”

Comments on Hope

  • “I was most intrigued by the sense that I may have felt physical changes caused by hope.”
  • Patient on placebo medication
  • “Hope helps us overcome hurdles that we otherwise could not scale, and it moves us forward to a place where healing may occur.”
  • James Groopman, M.D.
slide33

The ‘Mechanism’ of Religion and Prayer

Is There a Biology of Hope?

  • Adoption of healthy behaviors, shared ancestry, strong social support systems
  • Encourages hope, love, contentment, forgiveness and limits negative emotions
  • Religious people have enhanced immune function

Koenig HG. Handbook of Religion and Health, 2001.

positive emotions

‘Mechanism’ of Religion and Prayer

Is There a Biology of Hope?

Decreased activation of sympathetic nervous system and hypothalamic-pituitary-adrenal axis

Psychological effects (less anxiety)

Physiological effects (lower BP, HR, oxygen consumption)

Better health

Positive emotions

Recognizing Spirituality

  • There is a spiritual as well as a material quality in the care of sick people, and too great efficiency in material details may hamper progress.
  • William Mayo
  • Faculty meeting minutes
  • November 21, 1932
slide37

Barriers to Dealing with Spirituality

  • Ethical issues
  • Fewer physicians maintain religious or spiritual ties
  • Biomedical model of care
  • Outcomes of spirituality not taught in medical school
  • Some patients having daunting spiritual needs
  • Time constraints, lack of training and uncertainty

Mueller 2001

slide38

Reasons to Acknowledge Spirituality

  • Patients regard physical and spiritual health equally
  • Spirituality enhances coping skills and QOL and mitigates uncertainties during an illness
  • Acknowledgement may enhance cultural sensitivity
  • May enrich the patient-physician relationship
  • Goal of medicine is to cure disease when possible, but we must always alleviate suffering

Mueller 2001

slide39

Cancer – Power of Faith & Prayer

Conclusions

  • Prayer has been shown to help people with various physical and mental ailments in several ways
  • Religion and spirituality are dynamic interactions of complex variables involving cognitive, behavioral, interpersonal and physiological dimensions – some of which we have a minor understanding – and the supernatural, which we do not understand
slide40

Cancer – Power of Faith & Prayer

Conclusions

  • Science and medical research are ineffective and probably improper ways of trying to understand the power of faith and prayer
  • How God answers our prayers is unknown
  • God’s grace is greater than our skills and is immeasurable by our tools
