1. SURGICAL
MISHAPS Surgery is an area rife with medical errors. However, in a study of 15,000
medical records in hospitals in Colorado and Utah, it was revealed that
about 54% of surgical errors are preventable. The most common surgical mishap reported in the media is wrong
site surgery, like the man who had the wrong leg amputated. But
there are many more mistakes that take place that can be just as devastating.
As human beings, it is impossible to totally eliminate the possibility
of error, but there are steps that can be taken to raise the bar in providing
protection for the patient. This begins with remembering that the surgical
team is just that, a team. And every team member is dependent on the others
to make certain that the possibility of medical error is minimized. Pre-operative:
Post-operative
Anesthesia Another surgical area that is intensely vulnerable to medical error is anesthesia. A patient under general anesthesia is totally dependent upon the surgical
team for her welfare, even her survival. Again, it is impossible to
2. Diagnostic Errors: Delayed Diagnosis and Misdiagnosis Delayed diagnosis takes place when the physician fails to make a timely diagnosis. Delayed diagnosis often occurs because complaints that are symptomatic of serious problems when viewed in the light of certain risk factors are overlooked or dismissed. Misdiagnosis occurs when the wrong diagnosis is made. Diagnostic medical errors include:
In todays health care financial structure, it is sometimes difficult to gain access to as many test procedures as one would like, but every appropriate diagnostic technique should be used when making a diagnosis. The physician must become the patients advocate when dealing with the health insurer if that is what it takes to avoid medical error. In certain emergency situations, or in cases where a patient calls into the office with a complaint, it is not possible to perform a full battery of tests. However, there are certain symptoms that should be cause for immediate concern. These include:
It is also necessary to educate patients so they can act as their own advocates. In private practice, physicians need to get patients actively involved in their own healthcare:
When a diagnosis is particularly difficult, or there are any doubts,
call in a consulting physician. That way extra protection is provided
for the patient and the physician. The old adage there is safety
in numbers holds true in medicine: When two doctors have reached
the same conclusion, the chances are that it is the right conclusion and
the chance of medical error occurring is greatly reduced. An emergency situation is rife with the possibility for adverse events
and medical error. Whenever feasible contact the patients personal
physician. Many symptoms, such as chest pain, can be vague and it is extremely
helpful to know the patients history. Try to determine if the patient
has taken any medication prior to coming to the emergency room-and when-in
case there are any contraindications between the medication 3. INCORRECT TREATMENT Incorrect treatment follows closely on the heels of delayed diagnosis and misdiagnosis as a leading cause of medical error. Certain rules of safety should be followed:
4. MEDICATION ERRORS The greatest opportunity for error in the medical field is in the use
of medication. Studies report as many as 770,000 people are harmed or
killed from Adverse Drug Events (ADE) every year just in hospitals. That
does not include the people who are harmed by medication prescribed by
their private physician. One study in particular estimated that 9.7 %
of ADEs resulted in permanent disability, and the risk of death almost
doubles when an ADE occurs. In addition, the length of stay in the hospital
rises, as do the costs of the hospitalization. In a study at two hospitals
in Massachusetts, ADEs added as much as 4 and 1/2 days to the length of
the patients hospital stay, and up to $4,600 in unrecoverable costs
to the hospital. One of the great difficulties presented by ADEs is that they are very difficult to predict and no clear cause-and-effect relationship between age, number of drugs prescribed and co-morbidity exists. The one factor that has presented itself on a continuing basis is that ADEs with life-threatening consequences occur more often in ICU patients. However, this could simply be because the patients are already so ill. It is important to point out that an Adverse Drug Event is not necessarily considered a medical error. According to the IOM, an adverse event is defined as an injury caused by medical management rather than by the underlying disease or condition of the patient. For example, if a patient with no known allergies is given a drug and then has a life threatening allergic reaction to it, that is not a medical error. It is also important to remember that, according to the IOM study, hospitals report 7,000 deaths annually due to medical error involving medication error. Therefore this type of medical error must be closely examined. Preventing Medication Errors A new patient should be asked to list all current medications she is
taking-including over-the-counter drugs and herbal remedies.
The popularity of herbal remedies, or food supplements, has mushroomed
in the United States. One study estimates that as many as 60 million Americans
are taking at least one type of herb, but fewer than 50% report that use
to their physicians. This can be a serious problem in light of certain
herb-drug interactions that have become evident. For example, a study
by NIH found a significant interaction between indinavir, a protease inhibitor
used to treat HIV infection, and St. Johns wort (hypericum perforatum)
in which concomitant administration of St. Johns wort and indinavir
substantially decreased indinavir plasma concentrations. Another very popular herb, Ginkgo, may interact with anti-coagulant medications like heparin, aspirin and Coumadin and cause the blood to thin too much. This can cause serious bleeding disorders. The best policy is to make inquiring about the use of herbs and other
supplements part of your routine. Include this information in the patients
medical file, and update it regularly. Advise your patients that before
they begin taking any new herbal products, they should call you and make
certain there are no currently known interactions between the herb and
any medication they might be taking. When prescribing medication, make the patient aware of any possible side effects, do not assume she will read the printed information the pharmacy provides. Studies have shown that 20% of American adults are functionally illiterate, and that many are very successful in hiding that fact. Do not assume a patient can read and follow printed instructions. Tell the patient precisely how the medication should be taken, and that if she has any type of reaction, or any questions, she should call immediately. After explaining how to use the medication, make sure to give the patient
printed instructions to take with her. If medication is being administered in the physicians office, it is best that it be done under the physicians supervision. That way if the patient does have a reaction, it can be treated quickly. Any physician who administers IM or IV medication in the office should have the following available for emergencies:
The AHRQ conducted a study at three hospitals in the Northeast to see which medications were most likely to be involved in ADEs. The results were:
AHRQ studies have indicated that the majority of medication errors occur during ordering and administration. Every physician is warned never to phone in prescriptions, and although it is excellent advice, it is nearly impossible to put into practice. Therefore, the person taking the prescription should be asked to repeat it back including spelling out the name of the medication. There are a lot of look alike and sound alike medications, a partial list of which is included in this section. The only way to make certain the right medication will be given to the patient is to have the person dispensing it spell it out.
When writing a prescription, it must be clear and legible. Extra care
should be taken when writing out the dosage units and the times that the
medication should be taken. Also, blank pre-signed prescription forms
should never be left in the office or examining rooms. The physician must take extreme care when using abbreviations. Misinterpreted abbreviations are a common cause of medication error. The United States Pharmacopoeia (USP) lists the following as dangerous abbreviations: U unit can be mistaken for a zero or a four (4) resulting in overdose. Can also be mistaken for cc (cubic centimeters) when poorly written. µg micrograms can be mistaken for mg (milligrams), resulting in overdose. Q.D. Latin abbreviation for every day. The period after the Q has sometimes been mistaken for an I, and the drug has been given QID (four times daily) rather than daily. Q.O.D. Latin abbreviation for every other day. Misinterpreted as QD (daily) or QID (four times daily). If the O is poorly written, it looks like a period or I. SC or SQ Subcutaneous can be mistaken as SL (sublingual) when poorly written. TIW Three times a week can be misinterpreted as three times a day or twice a week. D/C Discharge also discontinue. Medications have been prematurely discontinued when D/C (intended to mean discharge) was misinterpreted as discontinue because it was followed by a list of drugs. HS Half strength can be misinterpreted as the Latin abbreviation HS (hour of sleep). cc Cubic centimeters can be mistaken as U (units) when poorly written. AU, AS, AD Latin abbreviations for both ears, left
ear, right ear can be misinterpreted as the Latin abbreviation
OU (both eyes), OS (left eye), OD
(right eye). 5. OBSTETRICAL MISHAPS The good thing about Obstetrical medicine is that it usually follows an orderly routine-the patient sees the doctor in the doctors office until it is time for delivery, then she is admitted to a hospital or birthing facility. There are some very obvious steps to help prevent medical error or adverse events during the pregnancy and office visit stage, beginning with patient education. The pregnant patient should be given information about:
It is not enough to just tell the patient. Materials should be provided to read on the topic, or videos to watch. Make her proactive in protecting herself and her baby during her pregnancy. In a large practice, a specific team needs to be assigned to each patient, so the same staff members interact with the patient throughout the pregnancy. That way the staff becomes familiar with the patient, and the patient becomes comfortable with the staff and is more inclined to ask questions or report any discomfort or unusual symptoms she might be having. Again, this helps safeguard the patient and the baby. Once it is time for delivery, teamwork begins in earnest. Ideally it should be a small team, with the physician as team leader. The team shares responsibility for the patient and for all decisions regarding care. Efficient, reliable team coordination and communication is critical. Whenever possible, the team members should remain constant. This allows the team to maintain structure, and to better develop and implement group planning and problem solving. Once the baby is born, close attention must be paid to patients exhibiting symptoms, or reporting complaints of postpartum depression. Do not hesitate to refer the patient to a mental health specialist. Once again, this might require the physician to take on the role of patient advocate. Not to do so can have tragic consequences in the life of both mother and child.
As medicine has entered the age of technology, health care professionals
Each of these uses of technology creates situations that are extremely vulnerable to medical error. To diagnose To provide treatment
To monitor the patient In addition to following all the aforementioned rules about equipment
maintenance and training, when it comes to home monitoring devices health
care professionals must add a crucial step-patient training It is extremely important that any patient using a home monitoring device
understand how it should work, and how to recognize if it is not working
properly. The patients family and/or caregivers should also be fully
trained. In addition, the physician who is in charge of giving the patient
the monitoring device should make certain that someone from his/her office
or facility routinely follows-up on all monitored patients to make certain
they are following the rules regarding utilization and maintenance. Another form of patient monitoring that is rapidly coming
to the fore is the implant. Heart pacemakers have been in use for many
years, and have become extremely reliable. As technology has advanced,
many patients now have access to phone in maintenance so they
can regularly check their pacemakers and be assured they are working properly.
One of the most exciting advances in the field of implants is the heart
defibrillator. This device came to the publics attention when Vice
President Dick Cheney had one implanted. This device has an amazing track record in studies. In fact, it performed so well that in a test group of high-risk patients who had heart attacks, the mortality rate was reduced by more than half. Experts estimate that there are currently 500,000 people in the U.S. who have had heart attacks in the past that can benefit from the defibrillator, and that there will be approximately 80,000 new heart attack survivors each year who will be candidates for the implant. The biggest safety risk of implants is the danger of malfunction, and occasional recalls. For this reason, the following steps must be taken when an implant is used:
To treat the patient Only professionals with complete training should use high-tech equipment, like the laser. In addition, the equipment must be properly maintained. Anyone using high-tech devices to treat patients should understand the following:
A patients comments regarding pain must not be dismissed as nerves, or cowardice. Treatment should be stopped immediately so the equipment can be checked to make sure it is functioning properly. Far better to have to reschedule an appointment than risk making a mistake that could harm the patient. Before using any new devices, everyone who will be using them to treat patients must be fully trained and tested to make sure they understood their training. 7. SYSTEM ERRORS In its report, the IOM stressed that most medical errors are system errors-in
other words, errors in the way care is delivered. In a major study supported by the AHRQ, it was discovered that in more than 75% of adverse drug events the root of the problem was failure at the system level. Facility-based Systems If the failures in the system can be corrected, medical errors can be greatly reduced. Two examples of this are:
Advances in technology have also enabled giant steps forward in reducing systems errors. Research is now taking place in which a computer is used to monitor the patient and make note of the following:
If any of these symptoms occur, the computer alerts the hospital staff. The computer will also alert the staff if any signs of a possible ADE occur, such as:
The computer system can be linked to the pharmacy, lab and treatment
facility so physicians can be notified immediately of any drug allergies
or food and/or drug contraindications. Until that technology is perfected and made widely available, it remains incumbent on human systems to prevent medical errors. To begin with:
Office-based Systems A critical factor in creating system-wide processes is to make sure that everyone who is part of the system is aware and involved. And everyone means exactly that, in both a facility and private practice. That extends to all support personnel, including the janitorial staff. If the janitor finds something on the floor, he/she should not assume it is trash and just throw it away. There needs to be a designated area where questionable papers/items can be deposited until they can be checked by one of the administrative staff. No one should ever answer questions outside his/her area of expertise. That includes physicians and nurses. There needs to be a checklist of things to remember when dealing with a new patient. This list can include:
The Importance of Risk Factors In patients with diabetes, an aggressive management approach must be
undertaken. Every time a diabetic patient comes to the office, check his
feet. In the appendix you will find a Diabetes Management Flow Chart.
Maintaining such a chart can greatly reduce the risk of delayed diagnosis
of complications of diabetes. Recent changes in the early warning signs of heart attack show marked differences between men and women. Make literature available to your patients, especially your female patients, so they recognize these symptoms. If a patient seems to be depressed, have him/her complete the Center for Epidemiologic Studies (CES) of the National Institute of Mental Health Self-Report Depression Scale, which can be found in the Appendix. Stay up-to-date on all changes relating to risk factors for major diseases.
Know when to perform certain health screening functions. Internal Communication
Even when phoning in a prescription, write it out first. Create a working atmosphere in which all personnel feel comfortable in reporting mishaps or errors. The Importance of Personal Diligence
Health care professionals must not forget the final, most important link in the health care chain-the patient. Patient education cannot be over emphasized. Patients must be fully informed about every aspect of their healthcare:
If surgery is necessary, the pre-op discussions must be thorough. Exactly what will happen, how long it will take, how the patient can expect to feel following the surgery, must be explained. Patients must be advised to tell the medical personnel in the operating
room why they are there, what operation they are supposed to have, etc.
If the patient has not had an in-person consultation with the anesthesiologist,
they must be directed to inform the anesthesiologist of any allergies
or adverse drug reactions he/she has ever experienced-just in case. Patients should be made to feel comfortable asking questions, asking
for clarification, asking for more information. Patients must be educated to know that it is critical for them to share
in the responsibility for their health care and their well being. The Quality Interagency Coordination Task Force (QuIC) is a group of Federal agencies in partnership with public and private sector groups working together to help make the health care system safer. The QuIC prepared a document for distribution to patients: 20 Tips to Help Prevent Medical Errors. A copy of this document that can be reproduced as a hand-out for patients is in the Appendix, or you can be prepare one that is better suited to your specific medical specialty. Following are 5 items from the complete list:
Tell the surgeon, anesthesiologist, and nurses if you have allergies or have ever had a bad reaction to anesthesia. Make sure you, your doctor, and your surgeon all agree on exactly what will be done during the operation. |
