[What determines a breast cancer patient's choice of hospital? The role of travel time, care history of the patient and the general practitioner's referral history].

OBJECTIVE

To examine to what extent patients' hospital choices are influenced by travel time, their care history, and their general practitioners' (GP) referral history.

DESIGN

Quantitative study.

METHOD

We used care claims data from 2015 of patients with breast cancer. We selected the initial care products of the breast cancer patients who had been referred to a hospital by a GP or GP practice. We used conditional logit choice models with 82 hospitals in the choice set to assess whether travel time to the hospital, care history of the patient in the preceding two years, and referral history of the GP were related to the choice of hospital. How often patients opted for a default choice hospital was also determined.

RESULTS

We identified 74,227 breast cancer care products representing the hospital choices of 70,608 unique patients (96% female; mean age 52.7 years) who originated from 4840 different GP practices. Travel time, the patient's care history, and GP referral history were all statistically significantly related to hospital choice. Patients more often visited a hospital where they had been before, with a shorter travel time, or where relatively more patients from the same GP practice went to for breast cancer care. The latter improved the model most, followed by patient's care history and travel time. Twelve percent of patients without previous care, and 7% of patients with a care history, did not opt for a default hospital; relatively often a university hospital or specialized hospital was chosen in these cases.

CONCLUSION

Next to travel time, the patient's care history and the GP's referral history clearly contribute to the hospital choice of breast cancer patients. A considerable cohort opts to receive care in a hospital that, based on travel time, the patient's care history and GP referral history, would not be the default destination.
