Development of a standard for hospital-based palliative care consultation teams using a modified Delphi method

Although palliative care consultation teams are rapidly being disseminated throughout Japan as a result of government policy, the role of these teams has not been standardized. The aim of this study was to develop a hospital-based palliative care consultation team standard. We adopted a modified Delphi method to develop a standard. Twenty-seven multiprofessional panelists were selected according to two criteria: adequate experience as part of a palliative care consultation team and representative of 16 palliative care-related organizations. Panelists rated the appropriateness of 33 statements in a provisional standard, which was generated by the authors, using a nine-point Likert-type scale in a first-round survey. We set two criteria for agreement: the median value was 8 or more, and the difference between the minimum and maximum was 4 or less. There were 15 disagreements in the first-round survey. Based on discussions through e-mails and a panel meeting, these 15 statements were dealt with as follows: one was rejected, one was combined with another statement, three were unmodified, and 10 underwent minor revisions. Moreover, two statements that generated agreement were divided into two statements each. Consequently, the number of statements was 37. In a second-round survey, three statements engendered disagreement and were modified. At the end of the process, there were 37 statements in four areas: "philosophy and policy," "structure for care provision," "contents of activities," and "quality assurance and care improvements." This standard may be useful as a clinical activity guide as well as a method to evaluate palliative care consultation teams.
