Medical error

Medical errors are mistakes that are made in a medical setting. Errors are made by every type of health care worker, and in every hospital and health care facility. In 2001, the U.S. Institute of Medicine estimated that, every year, 44,000–98,000 deaths in the USA were related to medical errors.

When an error occurs, the key question becomes, will it be recognized and corrected? Errors that eventually result in injury are typically compounded by subsequent errors of not recognizing that an error has occurred, and not taking remedial action.

Malpractice

If an error involves negligence and results in damage, as those terms are legally defined, it may be treated as medical malpractice and result in substantial liability. The possibility of legal liability can be a barrier to free discussion and disclosure of medical error, hampering efforts to reduce error. Thus, provisions for confidential reporting of errors can be useful.

Causes

In medical trainees, contributing factors include errors in judgment and breakdowns in teamwork (including supervision).

Prevention

Lessons from aviation

Plane crashes can be dramatic events, causing considerable loss of life and attracting wide publicity damaging to the reputation of the airlines involved, and weakening passenger confidence in air travel. Accordingly, all plane crashes and related serious incidents ("near misses") are exhaustively investigated in an effort to establish their precise causes. By comparison, most medical errors do not have the same wide impact, thus they seldom receive such intense scrutiny and analysis.

An adapted version of a "pilot's checklist" (designed to ensure that safety procedures are rigorously followed when preparing for take-off and landing) has been tested for usefulness in preparation for performing Cesarean delivery under general anesthesia.

Personnel factors

Reduction of duty hours

A survey of 200 residents who trained both before and after duty hours reform reported improved quality of life. However, "Residents reported that whereas fatigue-related errors decreased slightly, errors related to reduced continuity of care significantly increased."

Organizations promoting error reduction

Institute for Healthcare Improvement

The Institute for Healthcare Improvement (IHI) defines medical harm as "unintended physical injury resulting from or contributed to by medical care (including the absence of indicated medical treatment) that requires additional monitoring, treatment or hospitalization, or results in death." Previously, IHI initiated the 100,000 Lives Campaign. That campaign, participated in by 3,200 hospitals, is estimated to have reduced deaths of patients in hospitals by 122,000 in 18 months. The campaign focused on six "interventions" which had been identified as likely to reduce medical error:

• Use of Rapid Response Teams, teams of critical care experts, at the first sign of potential problems. Hospitals which have applied this intervention often show a reduction in Code Blue calls. Code Blue is a call for emergency response to imminent death, usually cardiac arrest. Use of Rapid Response Teams has increased dramatically in U.S. Hospitals, from near zero in 2003 to 1500 in 2006.
• Prevention of certain types of common hospital-acquired infections, nosocomial infections. Infections often follow surgery, surgical site infections, insertion of central lines or use of ventilators, ventilator associated pneumonia. Significant reduction may be achieved by procedures as simple as proper hand washing, use of clippers rather than razors to shave the site of surgery, or prompt administration of antibiotics following surgery.

IHI's second campaign, the 5 Million Lives Campaign, challenges 4,000 hospitals to adopt at least one of twelve interventions: the six original interventions and six more. The goal is encourage hospitals to improve their procedure enough to eliminate five million incidents of medical harm during a 24-month period, ending Dec. 9, 2008.

The Patient Advocate

Reduction of medical error can be effected on the patient side as well as on the side of the care giver, but only with vigilance on the part of the patient him or herself, or on the part of the patient's advocate.
