The suspensions come after Randall Saito left the Hawaii State Hospital on Sunday, took a taxi to a chartered plane bound for the island of Maui and then boarded another plane to San Jose, California. He was arrested in California on Wednesday.
Hawaii Department of Health Director Virginia Pressler says an internal investigation indicates employees inadvertently or intentionally neglected proper notification of supervisors and proper supervision of Saito.
It took the hospital at least eight hours to notify law enforcement that he was missing.

Pressler says the escape was a major breakdown of staff protocols.
Gov. David Ige says authorities and the public should have been notified much sooner. He says he's directed the attorney general to investigate.
Court records say Saito had relationships with three hospital staff members over the years. A 2010 evaluation by a psychiatrist says Saito had six significant relationships since he was committed to the Hawaii State Hospital in 1981.
The assessment by Dr. Gene Altman said three of the relationships were reportedly with women in the community, including Saito's first and second wives.
The evaluation said the other three were reportedly with hospital staff members.
Altman said Saito can be personable and has good social skills.
Saito was captured in the city of Stockton on Wednesday morning as the result of a tip from an alert taxi driver, the San Joaquin County Sheriff's Department said.
The department posted a photograph on social media showing Saito surrounded by three deputies at a gas station.
Hospital staff called 911 to report his disappearance shortly after 7:30 p.m. Sunday - two hours after he landed in San Jose, Honolulu police said. An all-points bulletin was issued at 8:30 p.m.
Honolulu police received a tip that Saito was on his way to a brother's home in Stockton and forwarded that information to authorities in California, Honolulu CrimeStoppers Sgt. Chris Kim said.

It wasn't immediately known how he was able to charter a plane. Police wouldn't provide details about his flight to California.
The FBI and U.S. Marshals Service reviewed security footage from San Jose International Airport in connection with the manhunt Tuesday, said Jon Vaden, a spokesman for the airport.
Late Tuesday night, the Hawaii Attorney General's office charged Saito with felony escape and issued a $500,000 bench warrant for his arrest.
Saito was committed to the hospital outside Honolulu in 1981, two years after he was acquitted in the killing of Sandra Yamashiro.
The victim was shot and repeatedly stabbed before her body was found in her car at a mall.
"He is a very dangerous individual," said Wayne Tashima, a Honolulu prosecutor who argued in 2015 against Saito receiving passes to leave the hospital grounds without an escort.
It was not immediately clear under what circumstances Saito left the facility in Kaneohe, a Honolulu suburb.
Hawaii State Hospital Administrator William May said officials are fully cooperating with law enforcement and appropriate steps would be taken if Saito had help from someone inside the facility.
Defense attorneys sought to have Saito released in 2000. But Jeff Albert, a deputy city prosecutor, objected, saying Saito "fills all the criteria of a classic serial killer."
In 1993, a court denied Saito's request for conditional release, saying he continued to suffer from sexual sadism and necrophilia.

The state Department of Health operates the hospital, which houses over 300 patients in Kaneohe. The department said it's investigating the escape.
"There is a serious lack of information for the public," said Nicholas Iwamoto, who was stabbed 18 times on a popular Hawaii hiking trail in 2009. His attacker was found legally insane and sent to Hawaii State Hospital. He was later granted conditional release to attend community college, a decision Iwamoto wasn't notified about.
"Public safety has certainly been compromised," Iwamoto said. "It's extremely alarming. But nothing from the state surprises me anymore."
Irving Tam, who has lived near the hospital in Kaneohe for about 30 years and was walking by the facility Tuesday, said he worries about hospital patients getting out in his neighborhood.
"When they do escape, especially someone with this kind of a record, there is a high degree of concern, he could be violent and who knows," Tam said. "That's why I have a gun, for this very reason. Hopefully I never use it."
Tam said he heard about the escape from a neighbor, not the police, hospital or the media, and that patients have gotten out several times in the past.
"This is not totally uncommon, we have had similar incidents in the past, and fortunately nothing has ever happened," Tam said.
Tam thought that someone with a violent past like Saito should closely monitored. "It is disturbing that he was given that much freedom," he said. "You would think he would be under heavier security."
Saito was the impetus for a rule change in 2003, when the state attorney general's office decided mental patients committed to Hawaii State Hospital have no legal right to conjugal visits.
The issue came to light when the hospital administrator learned Saito had been escorted home for weekend conjugal visits over two years. The administrator blocked the visits away from the facility and on its grounds.
Dangerous psychiatric patients have escaped recently from other facilities in the United States.
In Washington state in 2016 a man accused of torturing a woman to death broke out of the state's largest mental hospital. Anthony Garver crawled out of a window of his ground-floor room at Western State Hospital, rode a bus 300 miles to Spokane and was captured days later without incident.
After the escape Washington Gov. Jay Inslee fired the hospital's CEO and brought in the Corrections Department to inspect the building for security improvements.
A review of police reports by The Associated Press found 185 instances in the 3 years before Garver's escape in which Western State patients escaped or walked away.
