Page 266 E— Safety Activities in Health Care Organizations Numerous programs intended to promote patient safety can be found in hospitals, nursing homes, and other health care organizations. Hospitals, home health agencies, nursing homes, clinical laboratories, ambulatory surgery centers, and other health care facilities are licensed by state departments of health, which establish the terms under which they may operate. One way in which federal and state quality oversight requirements have historically been met is through reliance on private-sector accrediting bodies, termed deemed status. In most circumstances, deemed status arrangements allow a facility to meet government standards either through accreditation or directly through the government agency or through accreditation by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) or the American Osteopathic Association. A brief review of widely implemented safety programs in health care facilities, then, is grounded in the state licensing or, more likely, the voluntary accreditation standards of accrediting bodies such as the JCAHO. The JCAHO's standards for hospital accreditation,1 for example, include several facility-wide safety systems intended to ensure patients' physical safety and protection from environmental hazards and risks, accidents, and injuries including, for example, life safety; infectious disease surveillance, prevention,

Other traditional approaches to learning about error and how it might be prevented include morbidity and mortality conferences and autopsy. Life Safety Life safety refers to a set of standards for the construction and operation of buildings and the protection of patients from fire and smoke. These standards are based on the Life Safety Code, promulgated by the National Fire Prevention Association. Life safety standards that require fire alarm and detection systems are monitored and serviced routinely, that fire and smoke containment systems are in place, and that systems for transmitting alarms to the local fire department are functional. Facilities typically participate in fire and other disaster drills that help them identify weaknesses in their systems. By analogy, many other kinds of delivery-related simulations can probably help groups with differing disciplinary backgrounds learn to work cooperatively and effectively in, for example, the intensive care unit, emergency department, or operating room. The recent development of highly sophisticated operating room simulators has demonstrated their value both in teaching and for practitioners to practice recovering from crises. Infectious Disease Surveillance, Prevention, and Control Today, infection control covers a broad range of processes throughout the hospital. It requires epidemiological expertise and includes attention to medical devices (e.g., intravascular and alimentation devices, ventilators, equipment used for examination); the physical environment (e.g., air ducts, surfaces); surgical wound management; and carriage by employees and other health professionals. Such infection control processes are managed by individuals who are assigned the responsibility of surveillance, reporting, and investigating outbreaks of nosocomial infections (infections acquired while in health care that are unrelated to the original condition), and putting in place and monitoring the results of processes to prevent or reduce the risk of infectious transmission. In the best systems, data from many sources within the hospital—infection control committee surveillance, length-of-stay outlier reports, operating room logs, bacteriology and pathology reports, morbidity and

Page 268 mortality (M&M) conferences and so forth—can be brought to bear to identify trends and sources of infectious disease. Despite major efforts to decrease transmission, infection control remains a challenge to health care facilities. Indeed, in some ways it is more difficult now than in the past. Like other advances in patient care, the advent of antibiotics has dramatically improved patient care, but the emergence of antibiotic resistance means that new efforts of surveillance and prevention must be implemented in order to make progress against infection, and continuing efforts are needed to maintain earlier achievements. According to the Centers for Disease Control (CDC), nosocomial infections affect approximately 2 million patients annually in acute care facilities in the United States at an estimated direct patient care cost of approximately $3.5 billion per year (NCID/CDC&P). In long-term care facilities including nursing homes, CDC estimates that more than 1.5 million cases of nosocomial infection occur each year, an average of one infection per patient per year.2 Epidemiological studies have estimated that one-third of nosocomial infections can be prevented by well-organized infection control programs, yet only six to nine percent are actually prevented. Recognition of the danger of transmission of infection in the health care setting is credited to the insight of a Viennese obstetrician Ignaz Phillip Semmelweis in 1847. Semmelweis correctly identified the cause of an epidemic of childbed fever (puerperal sepsis) among maternity patients as originating from physicians who had previously done autopsies and then transferred bacteria (later found to be Streptococcus pyogenes) on their hands when they examined their patients. After Semmelweis introduced the practice of hand washing with a solution of chloride of lime (an antiseptic) before examination, maternal mortality decreased from 18 percent to 2.4 percent in the first month.3,4 According to CDC, even today, ''handwashing is the single most important means of preventing the spread of infection." Yet, repeated studies indicate that after more than 150 years of experience, lack of or improper handwashing still contributes significantly to disease transmission in health care settings5,6,7,8,9,10,11 Exhortations to personnel have not been effective, and some organizations have begun to look at system barriers to handwashing (e.g., the time required as well as the chapping and irritation caused by frequent handwashing) and ways to eliminate these problems by designing better hand hygiene processes.

Page 269 Morbidity and Mortality Conferences Morbidity and mortality (M&M) conferences began early in the twentieth century (1917) as a standardized case report system to investigate the reasons and responsibility for adverse outcomes of care. Mandated in 1983 by the Accreditation Council for Graduate Medical Education, M&M is a weekly conference at which, under the moderation of a faculty member, medical and surgical residents and attendings present cases of all complications and deaths. The value of the M&M conference is highly dependent on how the department chair uses it, but a recent national survey on attitudes and opinions of the value of M&M conferences found that 43 percent of residents and 47 percent of surgical faculty believed that the conference was an important and powerful educational tool.12 Lower rankings were given to its value in reducing error and improving care. M&M conferences are case-by-case reviews, with an emphasis on learning what might have been done differently in a given case rather than punishment, but they stress the value of knowledge, skill, and alertness to anticipate problems.13 They tend not to address systemic issues. Their value in improving the quality of care could be substantially increased if ongoing data are kept to identify repeated complications and time trends and if information from the M&M conferences is integrated with information from other available sources within the hospital. Autopsy Unexpected findings at autopsy are an excellent way to refine clinical judgment and identify misdiagnosis. Lundberg cites a 40 percent discrepancy between antemortem and postmortem diagnoses.14 Nevertheless, autopsy rates have declined greatly in recent years from 50 percent in the 1940s to only 14 percent in 1985.15,16 Autopsy rates in nonteaching hospitals are now less than 9 percent. When autopsies are completed, their value in improving care depends on reports reaching clinicians in a timely manner. Yet, many hospitals report long delays (several weeks or more) before clinicians receive autopsy reports. In general, rapid improvement requires shortening the cycle time between investigation and feedback to caregivers and managers, and timeliness in autopsy reporting is representative of all data gathering activities intended for quality improvement and reduction of errors.

Page 270 Risk Management Programs Originating with the increase in liability risk in the mid-1970s, hospital risk management programs have long been associated with the reduction of institutional liability and financial loss control.17,18 Controlling loss has focused historically on preserving the institution's financial (and human) resources. Risk management includes identification of risk and education of staff, identifying and containing risk after an event, education of staff and patients, and risk transfer. Educational efforts tend to focus on such topics as review of state statutes on informed consent, presentations by the hospital's defense counsel, and programs on medical and legal topics for physicians. Although effort has been made to move toward "primary" risk management that would focus on preventing adverse events from occurring, risk management is still focused largely on loss control. Although incident reporting systems are intended to include major events such as surgical mishaps, incidents have traditionally been greatly underreported and the reports that are fried have involved largely slips, falls, and medication errors that may have little consequence.19,20 The American College of Surgeons estimated in 1985 that only 5–30 percent of major mishaps are reported on traditional incident forms.21 Cullen et al. (1995) found that of 54 adverse drug events identified in their study, only six percent had a corresponding incident report submitted to the hospital's quality assurance program or the pharmacy hotline. Although risk management committees include a member of the medical staff, risk management has not been embraced at the organizational leadership level in its broadest sense of patient safety—protecting patients from any accidental injury. Risk managers interact when necessary with the administrator or chief executive officer, medical director or chief of staff, nursing director, medical records director, and chief financial officer, but the function of improved patient safety is not, typically, represented through risk managers on the governing board's executive committee or at corporate headquarters.
