The National Health and Family Planning Commission's new guideline on enhancing security in hospitals, though with good intention, is not enough to guarantee a safe working environment, medical workers said.

The commission and the Ministry of Public Security issued a document on their website on Tuesday in an attempt to ensure safer work environments in hospitals, suggesting at least three security guards be on patrol for every 100 medical workers, or at least one security guard for every 20 beds.

The document also suggested that hospitals set up alarm buttons in all departments, so that doctors can call security guards quickly when conflicts occur.
