Why may a physician be more involved in the purchase of larger equipment than he is in the purchase of daily supplies?

A physician may be more involved in the purchase of larger equipment due to the significant financial investment and long-term implications associated with such purchases, which often require careful consideration of clinical benefits and technology compatibility. Larger equipment can directly impact patient care and outcomes, necessitating the physician's expertise in evaluating options and making informed decisions. In contrast, daily supplies typically involve lower costs and standardized products that can be managed by procurement staff without the need for direct physician input.
