Intercessory prayer for the alleviation of ill health. - PubMed - NCBI
OBJECTIVES:
To review the effects of intercessory prayer as an additional intervention for people with health problems already receiving routine health care.
SEARCH STRATEGY:
We systematically searched ten relevant databases including MEDLINE and EMBASE (June 2007).
SELECTION CRITERIA:
We included any randomised trial comparing personal, focused, committed and organised intercessory prayer with those interceding holding some belief that they are praying to God or a god versus any other intervention. This prayer could be offered on behalf of anyone with health problems.
DATA COLLECTION AND ANALYSIS:
We extracted data independently and analysed it on an intention to treat basis, where possible. We calculated, for binary data, the fixed-effect relative risk (RR), their 95% confidence intervals (CI), and the number needed to treat or harm (NNT or NNH).
MAIN RESULTS:
Ten studies are included in this updated review (7646 patients). For the comparison of intercessory prayer plus standard care versus standard care alone,
overall there was no clear effect of intercessory prayer on death, with the effect not reaching statistical significance and data being heterogeneous (6 RCTs, n=6784, random-effects RR 0.77 CI 0.51 to 1.16, I(2) 83%).
For general clinical state there was also no significant difference between groups (5 RCTs, n=2705, RR intermediate or bad outcome 0.98 CI 0.86 to 1.11).
Four studies found no effect for re-admission to Coronary Care Unit (4 RCTs, n=2644, RR 1.00 CI 0.77 to 1.30).Two other trials found intercessory prayer had no effect on re-hospitalisation (2 RCTs, n=1155, RR 0.93 CI 0.71 to 1.22).
AUTHORS' CONCLUSIONS:
These findings are equivocal and, although some of the results of individual studies suggest a positive effect of intercessory prayer,
the majority do not and the evidence does not support a recommendation either in favour or against the use of intercessory prayer. We are not convinced that further trials of this intervention should be undertaken and would prefer to see any resources available for such a trial used to investigate other questions in health care.
