Health professionals' attitudes toward religiosity and spirituality: a NERSH Data Pool based on 23 surveys from six continents.

Background In order to facilitate better international and cross-cultural comparisons of health professionals (HPs) attitudes towards Religiosity and/or Spirituality (R/S) we updated the NERSH Data Pool. Methods We performed both a network search, a citation search and systematic literature searches to find new surveys. Results We found six new surveys (N=1,068), and the complete data pool ended up comprising 7,323 observations, including 4,070 females and 3,253 males. Most physicians (83%, N=3,700) believed that R/S had "some" influence on their patients' health (CI95%) (81.8%-84.2%). Similarly, nurses (94%, N=1,020) shared such a belief (92.5%-95.5%). Across all samples 649 (16%; 14.9%-17.1%) physicians reported to have undergone formal R/S-training, compared with nurses where this was 264 (23%; 20.6%-25.4%). Conclusions Preliminary analysis indicates that HPs believe R/S to be important for patient health but lack formal R/S-training. Findings are discussed. We find the data pool suitable as a base for future cross-cultural comparisons using individual participant data meta-analysis.
