Medicine ran in the Hiatt family. Kim's mother, Sharon Crum, was a nurse. Her father, Dan Hiatt, was a physician. He moved the family from West Virginia to Seattle when Kim was a few months old for his residency at the University of Washington.
It seemed like a natural choice when Kim decided to pursue a nursing degree at Pacific Lutheran University in Seattle. In 1986, she accepted an entry-level nursing position on Seattle Children's toddler floor, where she saw young patients with serious medical conditions that ranged from cancer to cystic fibrosis.
Hiatt immediately fell in love with the profession — and her patients. "She used to write poetry about her patients," Sharon says. "She just got so involved with them; she loved them, she loved little kids. She was good at her job, and she knew it."
Hiatt was particularly involved with her patients' families, her former co-workers and family recall. She was an avid photographer who liked to help the families make scrapbooks in the hospital.
"You are such a wonderful advocate for your patients and families," Hiatt's supervisor, Cathie Rea, wrote in Hiatt's 2009 annual performance review.
In her 2010 review, Rea raised the possibility that Hiatt might care too much and throw herself too deeply into patients' lives.
"Kim, you do a great job at the bedside with your patients and families," Rea, who ran Seattle Children's Hospital's intensive care units, wrote. "You are able to connect with families in a way that makes them feel valued and special. One of your peers commented that they would hate to see you get hurt by giving so much of yourself to families."
In that same review document, Hiatt was asked to describe what she liked about working at Seattle Children's. She wrote, "I love to teach parents and I love to get the parents handling their child as soon [and] as safely as possible and within the parent's comfort zone."
Hiatt was terrified. "Oh, God, I’ve given too much calcium," the nurse recalled her saying.
Hiatt's life was closely intertwined with the hospital. She met her spouse, Lyn, working there — and liked to bring her kids to work to show them what she did all day.
"She was really interested in taking care of kids in their last days of lives, and helping with the bereavement process," Lyn Hiatt says.
If Hiatt worked easily with patients, she did struggle with her co-workers at times. Her friends and family are the first to admit that Hiatt had a brash sense of humor, which could offend people.
"She had no filter," says Julie Stenger, a former Seattle Children's nurse who worked with Hiatt. "It was more to get a laugh from people."
There was a time when a co-worker felt she went too far. In the spring of 2008, a colleague filed a sexual harassment complaint against Hiatt. The documentation of the incident available to the public is incomplete; emails reference but don't fully describe it. The hospital disciplined Hiatt, requiring her to adhere to a "performance improvement plan."
Still, Hiatt's subsequent evaluations suggest the complaint was not considered a big problem. Instead, her supervisor at Seattle Children's describes it as something to work on. "I know this has been a difficult year for you and I am proud that you have rallied to a place where you seem more settled," Rea, the ICU director, wrote in her 2008 review. "Please be sure to continue to maintain your best professional behaviors and role model them for others."
Hiatt had her last performance review in August 2010, 20 days before the error. She had recently begun specializing her nursing skills, focusing on operating a life-support machine that helps especially sick children circulate blood. Her review that year described her as a "leading performer," giving her a 4 on Seattle Children's 5-point ranking scale.
Stenger, her former colleague, recalls it as a moment when Hiatt's children were starting to grow up — and Hiatt reacted by digging into her career even more.
"She was excited because her oldest kid was about to go to college and the youngest was kind of doing the pushing-away thing you do in middle school, so she was trying to find her niche professionally," says Stenger. "She really set her sights on that."
II. The "second victim" crisis
Albert Wu began studying medical errors in the late 1980s, as a newly minted medical school graduate. He'd been told to "study what you know." He knew, from firsthand experience, that his fellow residents made mistakes, sometimes serious ones — and didn't really know what to do in the aftermath. New doctors didn't want to tarnish their reputations by making a big deal out of a mistake, but they also found that the errors could haunt them.
In May 1989, Wu mailed a survey to 254 residents training at major hospitals in the United States about whether they'd made medical errors and, if so, how they coped.
114 residents returned the survey and admitted they had made a significant mistake. Some of them responded positively to their mistakes. They said the errors helped them get better, for example, at checking data. Others responded negatively, like the 13 percent who said they became more secretive about their errors.
But the most common thread was that residents just didn't know what to do. There was no course in medical school that helped them think about what it means to make a mistake in a profession where a patient's life or death can be at stake.
About half of all clinicians are involved in a "serious adverse event" each year
"Some of them had caused deaths," Wu says. "People were pretty devastated, but they were not talking to anyone about it."
Others began to build on Wu's findings, and they've consistently found three basic facts about the relationship between health care providers and their mistakes.
First, errors in medicine are common. One study found that 14.7 percent of medical residents said they had made a medical error in the past three months. A separate paper estimated about half of all clinicians are involved in a "serious adverse event" each year.
Second, in the wake of an error, many health care providers experience significant emotional and sometimes physical duress. One 2000 survey of more than 3,000 doctors in the United States and Canada found that 81 percent reported experiencing some degree of emotional distress in the wake of an error.
A small, qualitative study conducted in 2007 included 10 in-depth interviews with nurses who made mistakes giving medications. It found that two became depressed and considered killing themselves.
"I felt ashamed, making such a mistake, and that I abandoned others' trust in me," one nurse told researchers. "I felt I gambled with others' trust and love."
Much of the distress focuses, unsurprisingly, on the patient. Rick Boyte, a pediatrician in Mississippi, told me about the moments after a fatal error he had made when his needle accidentally punctured the lung of an already frail infant. The child died within an hour.
"I went and sat in my office for a while, and I just cried," he says. "It was a horrible disaster. I was wondering about the impact of the family, but nobody really knew what to say to me. I remember there were people who just wouldn't engage. They wouldn't look at me. I felt so amazingly terrible."
Third: Most health care providers think their co-workers don't experience emotional duress. This amplifies a sense of isolation, as, for example, a nurse assumes that other nurses navigate their mistakes just fine — that she is the only one who has trouble focusing on patients in the aftermath.
Carol-Anne Moulton is a practicing surgeon at the University of Toronto who struggled when complications happened during operations. If something unexpected happened, her heart raced and her stomach dropped.
But she couldn't tell if her co-workers felt the same way. They never really talked about things like that.
"Around me, it didn't seem like people were experiencing what I was experiencing," Moulton says. "I wondered whether I was unusual or whether this was a common phenomenon."
Moulton decided to answer her own question by talking to her co-workers and publishing the results in an academic journal.
As she interviewed colleagues, she learned about all sorts of emotional harms. One relatively senior surgeon retired early in the wake of an error. Another switched fields. About one-third of surgeons, she found, experienced traumatic stress in the wake of a major medical complication.
"It validated what I was feeling," Moulton says. "Some people who I thought were fairly stoic and resilient expressed way more emotion than I expected."
But here's the most interesting part of her study: All those surgeons who suffered quietly and alone thought that their co-workers were just fine. They assumed they were the only ones reacting emotionally to their errors. As one surgeon told Moulton, "I'm a little more sensitive than they are, and certainly a couple of them are absolute rocks."
Except they aren't: Moulton's paper — and the body of research it fits into — consistently finds that most providers aren't rocks at all.
"The way we've been trained, it's very much not a thing you talk about," Moulton says. "Personally, doing this study helped me with my own reaction. Once you realize you're not alone, you start understanding why you feel this way."
III. A fatal error — and two deaths
Around 9:30 am on September 14, 2010, a doctor instructed Kim Hiatt to administer 140 milligrams of calcium chloride to her patient, a frail 9-month-old infant.
The story of what happened that day is captured in more than 1,000 pages of hospital documents, employee testimony, and personal statements submitted to an ensuing state investigation into the error. These records were accessed through a public records request with the Washington State Department of Health. Vox has made the documents available at the bottom of this story.
Hiatt did the math in her head: Thinking that there were 10 milligrams of medication in every milliliter, she drew up a 14 milliliter dose and administered that through the patient's IV. She labeled the patient's name band and syringe with the time and size of the dosage.
Things in the children's intensive care unit began to get busy. Hiatt recalled the infant's nutritionist arriving with questions, and then her parents came for a visit.
Around lunchtime, another doctor noticed the patient's heart rate spiking. A nurse drew a blood sample that showed her calcium levels to be elevated. Hiatt described the dosage with another nurse and worked through her math.
The other nurse pointed out the error: There were 100 milligrams of medication for every milliliter. Hiatt should have only administered 1.4 milliliters — not 14.
Hiatt was terrified. "Oh, God, I've given too much calcium," the nurse, Michelle Asplin, recalled Hiatt having said.
Hiatt entered a note into the patient's record: "Miscalculated in my head the correct according to the mg/ml. First med error in 25 of working here. I am simply sick about it."
Cathie Rea, Hiatt's supervisor, was elsewhere in the hospital, but she read the note through a computer system. She quickly came down to the patient's room, escorted Hiatt to her car, and told her to leave campus. Immediately, Hiatt was isolated from her patient, her co-workers, and the hospital where she'd worked for two dozen years.
Alyse Bernal, a Seattle Children's spokesperson, declined to comment on whether this was the hospital's protocol for responding to serious medical errors.
"Seattle Children's is committed to providing the safest, most effective care possible," she said in a statement. "We were deeply saddened by the situation that occurred, and it spurred us to closely examine and improve our systems and processes."
Hiatt drove home, panicked about what would happen to her patient.
"[Kim] called me on her way home; she said, ‘I gave the wrong dose ... and she's going downhill and it's my fault and I don't know what to do," her widow, Lyn Hiatt, said. "She was worried about the parents and were the parents okay. She was trying to get information from the hospital, but they told her not to call."
Hiatt called the hospital daily to get an update from the patient's bedside nurse. "As a nurse, her wellbeing was foremost on my mind," Kim said in a statement after the error.
The patient died four days after the error. Seattle Children's Hospital fired Hiatt shortly afterward.
It's impossible to untangle how each of those events affected Hiatt's life, because they happened in such quick succession. Hiatt struggled with both the death of her patient and the loss of a career she loved. Friends and family say that after September, she was a different person.
