Connecticut Hospital Errors Increase While State Investigations Rare

Written by Lisa Chedekel

Incidents of pressure ulcers, wrong-site surgeries and other surgical errors reported by Connecticut hospitals have increased in the last five years, despite myriad efforts to curb them, a new state report shows.

At the same time, state health department investigations of many hospital adverse events, such as patient injuries from falls, perforations resulting in disability, and death or serious injury due to surgery, have been rare, data in the report shows. For example, of 196 cases reported since 2007 in which patients were injured by a perforation during a colonoscopy or other procedure, the Department of Public Health (DPH) investigated just 20, or one in 10 cases.

The new Adverse Event Report, prepared by the DPH, marks the first time that acute-care hospitals and other medical facilities have been publicly identified by name, as they report errors that caused harm to patients.

The five hospitals with the highest rate of adverse events in 2010, calculated per 100,000 inpatient days, were: New Milford Hospital (21.4), the Hospital of St. Raphael in New Haven (19.2), Sharon Hospital (17.2), Johnson Memorial in Stafford Springs (17), and William W. Backus in Norwich (16.2).  Other hospitals, including the Hospital of Central Connecticut and Saint Vincent’s Medical Center, had above-average rates of errors over the seven-year period from 2004-2010.


Because the errors are self-reported, state officials caution that some of the variation could be due to underreporting. The state does not conduct audits of medical or death records to validate the self reports, and national studies have found underreporting is a widespread problem. One study, published last May in Health Affairs, estimated that the system used in Connecticut and other states—voluntary reporting, based on federal patient-safety indicators—missed 90 percent of all adverse events.

The DPH reviews all hospital errors but does not investigate every case. In fact, the report shows, of 1,023 adverse events included in DPH’s database since 2007, the department launched investigations in only 23 percent of cases. Of 17 cases in which patients died or were seriously injured during surgery—a newer category added in 2010—only six were investigated.

The rate of DPH investigations into reported errors has dropped over the last five years – from 27 percent in 2007-2008, to 20 percent in 2009-2011. For cases in which patients acquired painful pressure ulcers during hospitalization, the investigation rate fell from 36 percent to 8 percent.

DPH officials said they target preventable errors that may indicate systemic problems or inadequate standards of care. The decision to investigate also is influenced by how often the type of event has been investigated before, and whether DPH is satisfied with a corrective plan that must be submitted by the hospital after an adverse event is reported.

DPH spokesman Bill Gerrish said the agency “has jurisdiction to investigate when there appears to be noncompliance with regulations or professional standards of care. Not all adverse event reports fall into these categories.”

The report notes that DPH used to receive funding for physician consultants in specialties including surgery, pediatrics and orthopedics—but as of 2010, “these resources were no longer available” to support investigations.

Overall, 1,637 adverse hospital events that resulted in patient harm were reported to the DPH from 2004 through May 2011, including 157 cases in which patients died. The most common incidents reported since 2004 were falls that resulted in injury or death. Hospitals reported 655 falls through May, 33 in which the patient died.

Perforations during open, laparoscopic or endoscopic surgery were the second most common source of errors reported, with 319 cases, including 32 deaths. Serious pressure ulcers acquired during hospitalization represented the third most common event, while foreign objects left in patients after surgery or other procedures was the fourth highest incident, with 105 cases reported.

Of 126 surgical incidents reported since 2005, 26 involved surgeries on the wrong site, 11 were wrong procedures, and two involved the wrong patients. One of the wrong-patient procedures involved a needle aspiration of the chest cavity.

The DPH report notes that there were more cases of wrong-site surgery in 2010 than in any previous year—seven, as compared to two in 2009—but the agency cautioned against drawing conclusions.

“As the reported number is influenced both by the number of events and the awareness of and willingness to report events, nothing can be concluded about frequency of errors based only upon the number of reports,” the DPH said. But “regardless of whether the increase in 2010 is statistically significant, any event of this sort is a serious concern.”

Under the state’s “adverse event” reporting law, hospitals have been required since 2002 to inform the DPH whenever patients suffer certain serious unintended harm. The legislation was intended to compel hospitals to improve care and to help patients assess the quality of care. But after the first reports became public, hospitals persuaded lawmakers to rewrite the statute in 2004, limiting the kinds of adverse events that must be divulged and keeping reports secret unless they led to an investigation.

In 2010, the law was revised again, this time requiring public reporting of errors and infection rates. While the new system is an improvement, patient-safety advocates say it still doesn’t go far enough.

“We don’t know how to deal with under-reporting,” said Jean Rexford, director of the Connecticut Center for Patient Safety. “We know it happens, but what are we doing about it?” She said it was alarming that three out of four reported events were closed without an investigation.

Ten of the state’s 30 acute-care hospitals reported at least one death or serious injury due to surgery mistakes in 2010. Backus Hospital reported four such incidents and Hartford Hospital reported three, with those seven cases accounting for nearly half of the 15 cases logged in 2010.

The report indicates that while some hospitals have made headway in reducing common medical errors over the last seven years, others haven’t. Overall among acute-care hospitals, the rate of reported surgical errors rose from .97 per 100,000 inpatient days in 2006, to 1.31 in 2010. The rate of post-admission pressure sores and other care-management problems rose from 1.70 in 2006, to 2.24 in 2010, despite increased attention nationally to the problem of patients developing bed sores.

Hospitals in the state, through the Connecticut Hospital Association, have actively collaborated in recent years to reduce pressure sores, hospital-acquired infections and falls. “There are new strategies in place to standardize the process of care” and prevent ulcers, falls and other adverse events, said CHA spokeswoman Michele Sharp.

The report indicates that both large and small facilities wrestle with common adverse events. Yale-New Haven and Hartford Hospital reported the highest numbers of incidents of foreign objects being left in patients in the seven years from 2004 through 2010; the Connecticut Children’s Medical Center, Bridgeport Hospital and the Hospital of Central Connecticut also were among the top five.

In numbers of reports of pressure sores, Yale and Hartford hospitals again were in the highest five, joined by Saint Vincent’s Medical Center in Bridgeport, and Danbury and Norwalk hospitals. While some hospitals reported only a few cases of perforations resulting in disability, others reported multiple incidents in a single year: In 2009, Norwalk had nine such cases, and Central Connecticut had eight. In 2010, each of those hospitals reported only one case.

The highest overall adverse-event rate over the seven years was reported by Sharon Hospital—24.4 per 100,000 patient days. The Hospital of Central Connecticut and Day Kimball Healthcare in Putnam had the second and third-highest rates, respectively.

In comments included in the report, most hospitals with high error rates described initiatives being undertaken to reduce adverse events. Yale-New Haven Health System, which includes Yale-New Haven, Bridgeport and Greenwich hospitals, said it encourages and expects the reporting of “all unexpected and adverse outcomes” in order to foster transparency and reduce the potential for harm.

The Hospital of Central Connecticut touted recent steps to reduce serious pressure sores. Backus Hospital officials said they had put an “extensive focus” on preventing falls, pressure ulcers, blood clots, hospital-acquired infections and medical errors. Hartford Hospital credited its patient-safety initiatives with reducing reportable falls by 45 percent from 2009 to 2010, and reducing pressure ulcers by 55 percent.

Among ambulatory surgical centers, the Endoscopy Center of Northwest Connecticut in Torrington reported the highest rate of adverse events in 2010, followed by the Middlesex Endoscopy Center in Middletown. DPH officials again cautioned that no conclusions should be drawn about quality based on the self-reporting.

Rexford and other advocates said in terms of making information available to citizens, Connecticut lags behind other states, such as Minnesota, which provides the public with a searchable database of adverse events.

In the report, DPH officials said they hope to improve the adverse event reporting program in ways that will promote patient-safety interventions. While they said the report alone should not be used as a gauge for a hospital’s quality of care, the department “encourages citizens, using this report, to ask their hospital or physician what is being done to prevent these types of events from occurring.”

  1. Thank you for this article it comes just the very week I wanted to speak with a reporter regarding my nightmare at a local hospital in 2007.

    I went to the hospital March 97 and was told I has pulmonary embolism and treated for 3 days and released.

    Every day for 2 1/2 weeks the VNA came to my house 2x a day injecting me with medication. I returned to the same hospital on March 19th a day before my birthday and at apx 8 :30 PM a team of white coats came in telling me I had additional PE and that I would need to go through an insertion of a filter following a procedure of TPA medicine to break the PE. The were suppose to go through my groin but they chose through my jugular vein and the nurse in radiology had been called back to work. He smelled of booze and cigarettes.

    The first procedure was done and then I was told the 2nd part would not take place I discovered an error was made. However, that is not the worse of this story!

    While in the hospital I was confined to bed and when asked for clean sheets was informed this was not a hotel.

    I would get into a glass shower weak and alone and a large window was behind the glass shower. I feared falling out of the window and when I advised the patient co-ordinator on a Friday before she left, she then reported I threaten to fly out of the window.

    They put me on suicide watch, my friend was with me during this process, spoke to two RN’s advising them that the woman misunderstood my comment. Yes, I wanted to leave that hospital but not that route.

    They plexi glassed my room except for the bathroom window which I was reported to want to fly out of.
    Allowed me to go into the bathroom and lock the door while the security guard sat outside doing a puzzle.

    There was string in the bathroom and glass vases in my room which if I were wanting to harm myself so much was available to do so.

    I requested to see the doc, which I had to wait till Saturday morning!!!!!!!!!!!!!!!!! When he came in I did not even allow him a chance to sit down. I gave him the grand tour of the conditions explain the real story and he dropped his head in shame and ordered the release of the guard.

    Nothing was done about the nurse who had been drinking who sedated me for the surgery, and I had marks from where they messed up on changing my fluids in my arm.

    I have had 3 doctors telling me I never had PE, I may have had it the 1st time, and another doc who said I had PE both times.

    I documented the condition of the room as they left the plexi glass up and the marks on my arm and I have a DVD that I want to release to the media.

    If I were someone who needed to be under suicide watch, well, I would have been able to get the job done!

    This is a disgrace and now in 2011 I was scheduled for a biopsy at one of the hospitals listed and after being told I had kidney cancer (prior to the biopsy) the doc had me sign a form for surgery. However, while I stood there in tears, she then added things to the document after my signature and well, I never went back.

    I went to another soc had another cat scan two months later the mass was gone!

    I have a fear of doctors but a horrific fear of hospitals!

  2. Sorry, I was so upset thinking of this matter it was March 07!
