Hospital policies on complementary medicine: a cross‐sectional survey of Australian cancer services

It has been reported that about 60% of patients commencing chemotherapy in Australia with curative intent and 47% of those receiving radiotherapy also use complementary medicine.1,2 Ingestible products are frequently used, but are often not discussed with the medical team, which increases the risk of interactions and other undesirable effects. Opportunity costs are another problem; while complementary medicine is typically used by people with cancer for supportive care and wellbeing, some use it to help treat cancer.2

Given the frequent use of complementary medicine by people with cancer, we surveyed Australian public and private hospitals with dedicated cancer services (1 May – 15 December 2016),3,4 to assess various aspects of cancer service coverage, particularly complementary medicine services. In this report, we describe hospital policies on complementary medicine and the availability of related information for patients. The study was approved by the human research ethics committees of the University of Western Sydney (reference, H11389), the University of Wollongong and Illawarra Shoalhaven Local Health District (reference, HREC/16/WGONG/178), and Calvary Health Care, Adelaide (reference, 16‐CHREC‐E011).

One staff member from the cancer service of each participating hospital (262 of 282 invited hospitals, 93%) completed a 52‐item electronic survey (online Supporting Information). Chemotherapy was provided by 207 of the participating services (79%) and supportive and allied health care by 196 (75%), including 66 (25%) that provided at least one type of complementary medicine service. Palliative care was provided by 168 hospitals (64%), surgery by 143 (55%), and radiotherapy by 143 (34%).

Ninety‐three responding hospitals (36%) could not provide responses to one or more of the five policy‐related survey questions. This was despite the option to complete the survey across several log‐in sessions and 223 of the respondents (85%) having administrator or management roles. Only 89 respondents (34%) were aware of the Council of Australian Therapeutic Advisory Groups (CATAG) position statement on complementary medicines,5 and only 31 of these respondents (35%) thought that their hospital policies were aligned with this statement.

A substantial proportion of hospitals did not have policies regarding complementary medicine practitioners or patient‐initiated complementary medicine use (Box). Most hospitals (229, 87%) had policies for documenting complementary medicines: 76 (33%) documented all complementary medicines (including patient‐initiated products) on medication charts, 88 (38%) documented only complementary medicines approved by medical staff, and 48 (21%) documented complementary medicine use only in the clinical history. The policy at 17 hospitals (6%) was that complementary medicines were never permitted, despite CATAG advice.5

In an adjusted backward multinominal logistic regression analysis, hospitals with cancer services without complementary medicine services were significantly less likely to have policies on complementary medicine practitioners and documenting complementary medicines (Box). Further, only 123 services (47%) provided complementary medicine information for patients, and 23 respondents (9%) did not know whether such information was available.

The differences in the awareness of and the availability of hospital policies and patient information about complementary medicine are concerning. Irrespective of whether a cancer service provides complementary medicine, consistent policies across Australian hospitals, and staff and patient awareness of these policies, are important because of the widespread use of complementary medicine. Stronger leadership is needed from peak bodies, such as the Australian Commission on Safety and Quality in Health Care and CATAG, to encourage Australian cancer services and hospitals to update or review their complementary medicine policies.
