The law requires doctors, dentists, optometrists, registered nurses and podiatrists to check their patients' drug histories on the state's prescription monitoring system, known as KASPER, before writing prescriptions. The proposed changes to the law would exempt patients in hospitals and hospital care as well as people receiving cancer treatment, among others.
The Independent newspaper reported a decline in fatal prescription drug overdoses in two eastern Kentucky counties, which officials attributed to the new law.
Stivers, the Senate president, acknowledged the rare bipartisanship behind the bill.
"This is a prime example where there is no politics or socio-economic status to the bill," he said. "Individuals can come together and come up with a real solution."
The legislation is House Bill 217. AP staff writer Roger Alford contributed to this story.
