ICT can have positive impact on health care, but there are also examples on negative impact of ICT on efficiency and even outcome quality of patient care. Medical informaticians should feel responsble for the effects of ICT on patients and public. Systematic analysis of ICT errors and failures is the precondition to be able to learn from negative examples and to design better health information systems.
This document contains summaries of a number of reported incidents in healthcare where ICT was the cause or a significant factor. For each incident or problem at least one link to a source will be provided. With the following list, we want to rise awareness on this important issue, and provide information for further reading.
This summary was inspired by a citation of Prof. Chris Taylor found in the report "Pathways to Professionalism in Health Informatics" of the UK Council for Health Informatics Professions: "Bad Health Informatics can kill". We would like to acknowledge the contribution of Dr. G.M. Hayes (President, UK Council for Health Informatics Professions; Chairman, Health Informatics Committee of the British Computer Society; President, Primary Health Care Group of the BCS) in collecting those examples.

|June 2014||Physicians expressed concerns on new clinical system||
Athens Regional Medical Center announced on Thursday the resignation of Senior Vice President and Chief Information Officer Gretchen Tegethoff.The notice of Tegethoff’s resignation came six days after Athens Regional’s former CEO and president James Thaw resigned. Both Thaw and Tegethoff were targeted in a May 15 letter signed by more than a dozen Athens Regional physicians who expressed their concerns over a new computer system they felt endangered patients.
The doctors noted such problems as “medication errors ... orders being lost or overlooked ... (emergency department) patients leaving after long waits; and of an inpatient who wasn’t seen by a physician for (five) days.” The EHR, designed by health care information technology company Cerner, is meant to improve efficiency and connectivity by providing doctors, nurses and other medical professionals with a shared data set. But physicians called the implementation of the system too rushed and noted intended users lacked “readiness” prior to implementation.

When Scott Erven was given free rein to roam through all of the medical equipment used at a large chain of Midwest health care facilities, he knew he would find security problems–but he wasn’t prepared for just how bad it would be.
In a study spanning two years, Erven and his team found drug infusion pumps–for delivering morphine drips, chemotherapy and antibiotics–that can be remotely manipulated to change the dosage doled out to patients; Bluetooth-enabled defibrillators that can be manipulated to deliver random shocks to a patient’s heart or prevent a medically needed shock from occurring; X-rays that can be accessed by outsiders lurking on a hospital’s network; temperature settings on refrigerators storing blood and drugs that can be reset, causing spoilage; and digital medical records that can be altered to cause physicians to misdiagnose, prescribe the wrong drugs or administer unwarranted care.
|Febr 2014||Ways EHRs can lead to unintended safety problems||
ECRI Institute PSO reviewed 171 health IT-related events submitted by healthcare facilities during a nine-week period. Health IT problem areas identified include: inadequate data transfer from one health IT system to another; data entry in the wrong patient record; incorrect data entry in the patient record; failure of the health IT system to function as intended; and configuration of the system in a way that can lead to mistakes.
Health IT must be considered in the context of the environment in which it operates during the three phases of any health IT project: planning for new or replacement systems, system implementation, and ongoing use and evaluation of the system. Shortsighted approaches to health IT can lead to adverse consequences.
|Nov 2012||Compilations of safety issues related to EHRs in Pennsylvania healthcare facilities||From Healthcare IT News: With limited data available
on potential safety risks related to EHRs, the Pennsylvania Patient Safety
Authority has published one of the largest compilations of safety issues
related to EHRs in Pennsylvania healthcare facilities in its December Pennsylvania
Patient Safety Advisory released today. ...
Of the 3,099 EHR-related events analyzed by the Authority, 2,763 (89 percent) were reported as "event, no harm," meaning an error occurred but there was no harm to the patient. Ten percent of the reports (320) were reported as "unsafe conditions," which also did not result in a harmful event. Fifteen reports involved temporary harm to the patient due to the following: entering the wrong medication, ignoring a documented allergy, failure to enter lab tests and failure to document.
|Dec 2011||Computer worm forces hospitals to turn away patients||A damaging, fast-spreading computer bug forced an Atlanta-area hospital system to shut its doors for nearly three days last week and divert ambulances to other facilities. Gwinnett Medical Center's two campuses, in Lawrenceville and Duluth, Ga., were forced to declare "total diversion" status and turn away all but extreme trauma cases beginning Dec. 7, when the hospital's IT department detected malware on its network. This infection was most likely the result of an infected USB and perpetuated across the network as a result of minimally protected medical systems attached to their network.|
|April 2011||Review of Reported Clinical Information System Adverse Events in US Food and Drug Administration Databases found 120 reports||Background: The US FDA has been collecting information
on medical devices involved in significant adverse advents since 1984. These
reports have been used by researchers to advise clinicians on po-tential
risks and complications of using these devices. Objective: Research adverse
events related to the use of Clinical Information Systems (CIS) as re-ported
in FDA databases.
Methods: Three large, national, adverse event medical device databases were examined for reports pertaining to CIS.
Results: One hundred and twenty unique reports (from over 1.4 million reports) were found, represen-ting 32 manufacturers. The manifestations of these adverse events included: missing or incorrect data, data displayed for the wrong patient, chaos during system downtime and system unavailable for use. Analysis of these reports illustrated events associated with system design, implementation, use, and support.
Conclusion: The identified causes can be used by manufacturers to improve their products and by clinical facilities and providers to adjust their workflow and implementation processes appropriately. The small number of reports found indicates a need to raise awareness regarding publicly available tools for documenting problems with CIS and for additional reporting and dialog between manufacturers, organizations, and users.

|March 2011||A study of an Enterprise Health information System by Jon Patrick, University of Sydney||This is a study into the roll-out of Cerner FirstNet into EDs in NSW. The original study was issued in Dec 2009 (Part 3.1). This has been added to with a new study in 2010 consisting of discussions with 7 ED Directors (Part 3.2), discussions with software experts who do performance evaluations on Cerner sites (Part 3.3), and reviews of Entity-Relationship Diagrams (Part 3.4), Schema descriptions and data tables from customer installations (Part 3.5 & 3.6). All this information is coalesced to establish a much more detailed picture of a Cerner installation (Part 3.7). A number of weaknesses are identified in the design and implementation and risk assessments are recommended for organisations using this software or intending to use it. Regulations that might minimise the risks to users of health software are recommended (Part 3.8). An alternative architecture and method for constructing clinical information systems is presented (Part 3.9). I would like to acknowledge the postgraduates who assisted in collecting the data and colleagues who offered advice and edited the written materials.||Complete report|

|February 2009||Barts virus caused ‘major internal incident’||Last November’s Mytob worm attack on the network of Barts and the London NHS Trust led to its ‘major internal incident' plan being activated, with some ambulances redirected from A&E. The network failure was one of the most severe known to have occurred at an NHS hospital trust. To clean and restore the infected network, Barts had to draft in help from neighbouring trusts and a 40-strong team from BT. An interim report on the incident says clinical services were affected, though effective alternative arrangements worked. However, it also says that protracted delays in getting the network back up, and in providing access to the clinical systems that run on it, created potential risks to patient care.||e-Health Insider. 15 Jan 2009.|
|January 2009||Software glitch causes incorrect medication dosages||Patients at VA health centers were given incorrect doses of drugs, had needed treatments delayed and may have been exposed to other medical errors due to the glitches that showed faulty displays of their electronic health records, according to internal documents obtained by The Associated Press under the Freedom of Information Act. The VA's recent glitches involved medical data -- vital signs, lab results, active meds -- that sometimes popped up under another patient's name on the computer screen. Records also failed to clearly display a doctor's stop order for a treatment, leading to reported cases of unnecessary doses of intravenous drugs such as blood-thinning heparin. According to interviews and the VA's internal memos, the glitches began after the VA distributed its annual software upgrade last August .'' By early October, hospitals began reporting the troubling problems: When doctors pulled up electronic records of different patients within 10 minutes of each other to offer treatment advice, the medical information of the first patient sometimes displayed under the second person's name. In some records, a doctor's stop order for intravenous injections also failed to clearly display." No explanation of what caused the software problem, which was reportedly fixed in December.||MSNBC|

|May 2007||Software incompatibility was part of a chain of events leading to the wrong patient getting an appendectomy.||The mistake occurred Nov. 14 when two female patients were scheduled for computed tomography, or CT scans, according to the state report. The first patient underwent an appendectomy that very evening because of the CT results. But the surgery was unnecessary. The next day, a radiologist discovered the patient's CT scan was actually that of a second patient. Hospital staff told state inspectors that the technologist had trouble starting the required intravenous line for the first patient and took her out of the CT scan room to complete that task. However, the patient's information had already been entered into the computer system for the CT scan. After the second patient's scan was completed, a radiology technician noted the error, removed the first patient's information and entered information on the second patient. When the first patient's information was deleted from the computer in the scan room, it was not deleted from the computer system used by the radiologist. "This was due to an incompatibility of the software between the two systems," the state report said.|
|Baby died after untrained doctor took 50-50 gamble on pressing right button||A baby boy died after an untrained doctor pressed the wrong button on his bypass machine because it was a less "horrid" colour than the other, an inquest heard yesterday. Four-month-old Thomas Smith was on a heart and lung bypass machine when Simon McGuirk, a cardiac surgical registrar, accidentally turned it off. Mr McGuirk said that he did not know whether to press the orange or blue buttons to restart the machine, so opted for the blue. It sent the machine into reverse, sucking blood from Thomas's body. He died a short time later.||Telegraph.co.uk 21/03/2006|

The authors characterized errors in several converging aspects of the drug ordering process: confusing on-screen laboratory results review, system usability difficulties, user training problems, and suboptimal clinical system safeguards that all contributed to a serious dosing error.||Horsky J et al.

According to insiders, callers trying to reach their local police headquarters, fire service or ambulance service were unable to get through to the operators for significant periods. The London Ambulance Service admitted last week that there had been long delays on Saturday - the longest for 20 minutes.

The figure was revealed in a report into the way three health boards - Tayside, Forth Valley and Fife - managed their cervical screening services. The authorities admitted at the end of last year that nearly 15,000 women were incorrectly left off a list for smear tests. The problem arose with a computerised system which calls women aged between 20 and 60 for routine examinations. Women who failed to respond to three invitations for smears before 1994 were suspended from the system. This meant they were not invited back for screening again - which is against national guidelines.||BBC News April 26, 2000|

Margaret Grieveson, the hospital physicist, wrongly assumed that a 'correction factor' which adjusts the dose according to the distance of the radiation source from the skin, had not been built into the Eclipse 6/130 computer. It had arrived without a manual. A report into the disaster, published in 1993, said that out of 1,075 patients who had received wrong doses, more than 401 had since died and a further 91 had suffered a recurrence of their cancers, including 26 who had surgery to remove their bladders. The report also said it was impossible to say whether those who died would have survived if it had not been for the mistake.||
