Objective: There has been increasing recognition and
acceptance of the importance of addressing existential and spiritual
suffering as an important and necessary component of palliative
medicine and end-of-life care in the United States. This paper seeks to
empirically and systematically examine the extent to which there is an
adequate scientific research base on spirituality and its role in
palliative care, in the palliative care and hospice literature.
Methods: We sought to locate all empirical studies published
in five palliative medicine/hospice journals from 1994 to 1998. The
journals included: American Journal of Hospice and Palliative
Care, Journal of Palliative Care, Hospice
Journal, Palliative Medicine, and The Journal of Pain
and Symptom Management. Journal contents were searched to identify
studies that included spiritual or religious measures or results. Case
studies, editorials, and theoretical or descriptive articles were not
included in the search.
Results: During the years 1994–1998, 1,117 original
empirical articles were published in the five journals reviewed. Only
6.3% (70 articles) included spiritual or religious variables. This
percentage, while low, was better that the 1% previously reported in an
examination of studies published in Journal of the American Medical
Association, The Lancet, and New England Journal of
Medicine.
Significance of results: While researchers in the field of
palliative care have studied spiritual/religious variables more
than other areas of medicine, the total percentage for studies is still
a low 6.3%. To move the field of palliative medicine forward so
appropriate guidelines for spiritual care can be developed, it is
critical that good research be conducted upon which to base spiritual
care in an evidence-based model. Recommendations are made for future
studies on spiritual care in palliative medicine.
