Background. The current study was performed to develop a consensus-based core inventory of key performance indicators (KPIs) to be used in capturing the impact of pharmaceutical care in healthcare facilities that employ integrative medicine paradigm in Palestine. Methods. A panel of healthcare professionals and risk/quality assurance managers was composed employing a judgmental sampling technique. The study tool was a questionnaire. Views and opinions of the panelists on the roles of pharmacists in caring for patients admitted to or visiting healthcare facilities that employ integrative medicine were collected using 11 statements. An initial inventory of activities and services that potentially can be used as KPIs was compiled from the literature and interviews with key contact experts in the domain. Three iterative Delphi rounds were conducted among the panelists (n = 50) to achieve formal consensus on the KPIs that should be used. The consensus-based KPIs were ordered by the scores of the panelists. Results. A total of 8 consensus-based KPIs were developed. The KPIs related to the number of problems related to medications and complementary and alternative medicine (CAM) that were resolved by pharmacists and CAM practitioners ( < 0.0001), number of patients for whom reconciliations were documented ( < 0.0001), number of patients receiving direct, comprehensive, and/or collaborative care ( < 0.0001), and number of patients for whom pharmacists and CAM practitioners were involved in implementing a therapeutic plan ( < 0.05) were rated significantly higher than the KPI (#8) related to the participation in multi-healthcare provider discussions/deliberations. Conclusions. Consensus-based KPIs that can be used in capturing the impact of evidence-based CAM and pharmaceutical care of patients in healthcare facilities that employ integrative medicine paradigm were developed. Future studies are still needed to investigate if implementing these KPIs might promote evidence-based CAM and pharmaceutical care in healthcare facilities that employ the integrative medicine paradigm.
