Preventability of Malpractice Claims in Emergency Medicine: A Closed Claims Study We conducted a retrospective study of 262 malpractice claims against emergency physicians insured in Massachusetts by the state-mandated insurance carrier; these 262 claims were closed in the years 1980 through 1987. A total of $11,800,156 in indemnity and expenses was spent for these 262 claims. In 2II cases, the allegation was failure to diagnose a medical or surgical problem. One hundred eighty-four of these cases were included in the following eight diagnostic categories: chest pain, abdominal pain, wounds, fractures, pediatric fever/meningitis, aortic aneurysm, central nervous system bleeding, and epiglottitis. These eight categories accounted for 66.44% of the total dollars spent for the 262 claims. Because of the high incidence and dollar losses attached to these eight diagnostic categories, the Massachusetts Chapter of the American College of Emergency Physicians (MACEP) has developed clinical guidelines for the evaluation of these high-risk areas. Of the 184 high-risk claims, 99 claim files were reviewed; 45 of these reviewed claims were judged by physician reviewers as preventable by the application of the MACEP high-risk clinical guidelines. From 22.26% to 46.4% of the $ii,800,156 spent on the 262 claims could have been saved by the application of the MACEP clinical guidelines.

Ann Emerg Med August 1990;19: 865-873.] INTRODUCTION The Massachusetts Chapter of the American College of Emergency Physicians (MACEP) began working on a comprehensive risk management program for emergency physicians in Massachusetts in 1985 with the first of two closed claims studies. The records reviewed were those of claims filed against physicians practicing emergency medicine in Massachusetts who were insured by the Joint Underwriters Association (JUA), the state-mandated malpractice insurance carrier. The first study reviewed 79 JUA claims against emergency physicians that were closed during 1974-1983J The distribution of claims against emergency physicians in Massachusetts was found to be similar to that found in other studies defining the highrisk diagnoses as published by the American College of Emergency Physicians 2 and Trautlein; 3 that is, missed myocardial infarction, missed acute abdominal problem, wound infections/retained foreign bodies, missed fractures, and missed meningitis. Other studies since then have confirmed these data.4, s These diagnoses account for about 25% to 40% of all claims against emergency physicians and about 60% of total dollars paid out in claims. 2 Following this first study, MACEP began to plan a comprehensive risk management program. MACEP's premise was that by specifically educating physicians about the high-risk diagnoses, claims in these areas could be reduced. MACEP developed clinical guidelines for these high-risk areas. Rather than being a "laundry list" of diagnostic possibilities, the guidelines were meant to remind practitioners of potential pitfalls in the evaluation of these diagnostic areas. Each guideline consisted of a one-page sum-

MALPRACTICE CLAIMS Karcz et al

History Pain in chest, jaw, upper abdomen (indigestion), arms Quality: burning, crushing, tight, pleuritic, sharp Location Radiation: left/right arm, jaw, back Associated symptoms: Shortness of breath, nausea, diaphoresis, syncope, vomiting Risk factors: smoking, arteriosclerotic vascular disease, hypertension, family history, diabetes, cocaine use, cardiac history Physical examination Chest wall abnormalities/tenderness Lungs: rubs, adventitial sounds Cardiac: rubs, clicks, murmurs ECG Helpful if abnormal or if changed from old ECG. All bets are off if ECG is normal. Defend your diagnosis Support your diagnosis from history, physical examination, associated symptoms, and risk factors. Watch out for pneumothorax, aortic dissection, pulmonary embolus If sending home Document history, physical examination, and ECG as appropriate for discharge diagnosis. Give specific follow-up instructions. Assessment of chest pain as the presentation of ischemic heart disease It needs to be stated from the outset that at the present state of the art, it is not possible to diagnose ischemic heart disease with 100% accuracy. The best of clinicians will miss a certain percentage of cases and will undoubtedly admit many cases in which acute myocardial infarction will be ruled out. Given this, perhaps the most important element relating to

The guidelines were intended as drafts that would be revised by MACEP to reflect changing practice patterns, new technology, or legal precedents. Patient instruction sheets were also developed for use in these high-risk areas and are an inte44/866

proper evaluation of chest pain in the ED is a thorough and thoroughly documented history and physicial examination. The decision to admit a patient should not be dependent on an abnormal ECG because, in fact, a normal ECG does not rule out ischemic heart disease.

History The history should specifically note the presence or absence of the following: Chest pain: Or its equivalent, eg, heartburn, indigestion, discomfort, arm or jaw pain Associated symptoms: Diaphoresis, nausea, anxiety, palpitations, shortness of breath, "sense of doom," weakness Medical history: Known coronary artery disease (history of angina or myocardial infarction), ? nitroglycerin use It may also be useful to elicit information regarding the duration, type, location, radiation, and aggravating/relieving factors relating to the pain. Risk factors (sex, age, hypertension, family history, smoking, diabetes mellitus, cholesterol) may also be elicited and recorded.

Physical examination Physical examination should focus on the heart, lungs, chest wall, and abdomen, as well as the general appearance of the patient. The presence or absence of murmurs, rubs, extra sounds, irregularities, gallops, or rales should be noted. The ECG should be examined carefully for signs of acute ischemia or infarction. Comparison should be made to old ECGs when available. The diagnosis should follow naturally and logically from the history and physical examiantion and should be consistent with findings. A differential diagnosis and documentation of the thought process used in determining the final diagnosis is useful.

gral part of the MACEP guidelines. The chest pain guideline is reproduced here in its entirety (Figure 1). The MACEP guidelines were designed to improve the emergency physician's ability to recognize and/ or appropriately treat ischemic chest pain, acute abdominal events, fractures, wounds, and pediatric fever/ meningitis. The Massachusetts JUA recorded 262 claims against emergency physicians that were closed from 1980 through 1987. The distribution of all 262 claims by diagnosis is shown in Table 1; the distribution by year is shown in Table 2. Annals of Emergency Medicine

METHODS For the five identified high-risk clinical areas, each JUA claim record that was available and contained a copy of the ED record was reviewed. Ninety-nine claims were reviewed during January 1989, when the JUA permitted MACEP time-limited access to closed claims against emergency physicians from 1980 to 1987; these claims files were retrieved by the JUA for MACEP from the JUA files. A p h y s i c i a n reviewer read through the claim file using a threepage worksheet for items contained within the case file and a one-page clinical audit checklist specific for 19:8 August 1990

Further history, physical examination, and laboratory data may be useful in evaluating the total picture of the patient's problem but should not be allowed to obscure the basic findings.

In the ED, ischemic heart disease is frequently a clinical diagnosis, which relies more heavily on the thoughtful judgment of the clinician than any single finding or laboratory test.

Treatment/Disposition When it has been determined that a patient does not appear to have ischemic chest pain or any other significant illness requiring immediate treatment or hospitalization, appropriate discharge instructions should be given to the patient and/or the patient's family. ]-he patient should be encouraged to follow-up with his or her physician as soon as possible (see below).

Summary Determination of ischemic cause for chest pain (or its equivalent) is generally a clinical judgment. The physician should have a very high index of suspicion, with a low threshold for admission in those patients with chest pain and a history suggestive of a cardiac cause (associated symptoms, risk factors, etc). In general, the history is essential and the ECG should be viewed as only an adjunct to the clinical evaluation. References 1.

Physician reviewers completed the clinical audit checklist from the data obtained from the ED record only; whatever was stated in addition in deposition or in other parts of the JUA file was not used for clinical evaluation of the care rendered. The 14 physician reviewers were board certified or board prepared in emergency medicine and were engaged in the active clinical practice of emergency medicine. They were asked to judge whether the claim outcome could have been affected by use of the MACEP clinical guideline. The level of d o c u m e n t a t i o n was 19:8 August 1990

evaluated by the physician reviewer; if an ED record indicated a thoughtful and complete history and physical examination, application of the MACEP clinical guideline would not have had an effect on the outcome of the claim. Conversely, medical records with minimal documentation could have been improved by the app l i c a t i o n of the MACEP clinical guideline. Physicians were required to support their j u d g m e n t s of MACEP guideline effects t h r o u g h w r i t t e n c o m m e n t s in the three-page worksheet. The physician reviewer had access to the entire claim file including Annals of Emergency Medicine

the outcome and indemnity paid. Because of time-limited access to the claims files, each claim file was reviewed by only one physician; all of the resulting w o r k s h e e t s were reviewed by one of the authors to ensure that the checklist responses were consistent with the physician reviewer's opinion about claim preventability. Initially, guidelines were developed for only the five high-risk areas mentioned earlier. Review of the data by diagnosis (Table 1) revealed that large dollar losses were also attributable to failure to diagnose aortic aneurysm, central nervous system bleeding, and 867/45

For the analysis of the data in this study, these three diagnoses were included in tabulation of highrisk data; none of these charts was r e v i e w e d in the p r i m a r y s t u d y as MACEP clinical guidelines for these three diagnoses were not yet available.

the c l i n i c a l guideline, it was ass u m e d that half the total a m o u n t spent on i n d e m n i t y and expenses would have been saved. Of the 16 claims classed as mitigat a b l e by t h e a p p l i c a t i o n of the MACEP guideline, seven were actually judged by the original reviewer to be either mitigatable or preventable. In order not to overstate the impact of the MACEP clinical guidelines, these cases were c o u n t e d as mitigatable, even though secondary review of the worksheets by one of the authors would have placed them in the category of preventable claims. If the physician reviewer judged that the clinical guideline would have had no impact, it was assumed that no dollars spent on the case would have Annals of Emergency Medicine

been saved. A judgment of indeterminate effect of the guideline by the physician reviewer meant that the reviewer could not determine whether the guideline would have had an effect on the dollars spent on the case; cases where the physician reviewer made no judgm e n t , that is, left that audit i t e m blank, were also included in this category. For purposes of data analysis, indeterminate claims were treated as if no dollars spent on the case would have been saved.

M o s t of the n u m b e r and dollars of claims were in the category of failure to diagnose (Table 1). The leading allegations of failure to treat involved release of suicidal or h o m i c i d a l psyc h i a t r i c p a t i e n t s and t h e i m p r o p e r t r e a t m e n t of o p h t h a l m o l o g i c probl e m s r e s u l t i n g in v i s u a l loss. Difficulties with intubation were the cause of the largest awards in the category of procedure complications. The cases judged preventable were m o s t p r o n o u n c e d in a review of the chest pain cases, that is, cases of ischemic chest pain that were missed on initial presentation.

DISCUSSION T h e goal of the MACEP risk mana g e m e n t p r o g r a m is to i m p r o v e the q u a l i t y of e m e r g e n c y m e d i c a l care and to reduce the incidence of malpractice claims and the aggregate cost of m a l p r a c t i c e claims. W i t h increasing regulation in h e a l t h care and d e m a n d s for standards or guidelines for care, it behooves physicians in a particular specialty to set their own s t a n d a r d s or g u i d e l i n e s before t h e y are i m p o s e d by outside interests. 19:8 August 1990

Various specialty societies have established standards or guidelines for the care of certain conditions 7-tt and m a n y m o r e are currently developing such standards or guidelines for care. G e n e r a l l y these are developed by the consensus m e t h o d 12 and are a reflect i o n of t r a d i t i o n a l m e d i c a l t e a c h i n g as found in the medical literature, filtered through the expertise and perspective of clinicians. A recent article 13 dealt w i t h t h e i m p l i c a t i o n s of guidelines for medical practice. Physicians frequently express concern t h a t g u i d e l i n e s w i l l serve as a t e m p l a t e for plaintiff attorneys to use against them; professional group guidelines codify and organize an app r o a c h to a c l i n i c a l s i t u a t i o n . T h e MACEP guidelines contain nothing that is not already in textbooks and j o u r n a l articles. T h e c u r r e n t litigation process requires the standard of c a r e to be r e s t a t e d a n d r e d e f i n e d through expert witnesses in each case. Expert witnesses are n o t always engaged-in the practice of emergency m e d i c i n e a n d are n o t i m m u n e to their own monetary interests. A guideline reflects a s t a t e m e n t of clini c a l e x p e r t i s e of m a n y p h y s i c i a n s w i t h o u t specific m o t i v e s other t h a n i m p r o v i n g t h e q u a l i t y of m e d i c a l care. T h e s e g u i d e l i n e s can help t h e defense in malpractice cases by s h o w i n g t h a t t h e p h y s i c i a n defendant indeed adhered to an adequate level of care. H o w e v e r , a d h e r e n c e to g u i d e l i n e s cannot guarantee that a bad o u t c o m e will n o t occur in a particular p a t i e n t e n c o u n t e r or that a c l a i m will not be filed in such a case. Physicians can be sued and c l a i m s p a y m e n t m a d e e v e n if t h e care r e n d e r e d was n o t substandard. 14 Malpractice claims are a result of 19:8 August 1990

bad o u t c o m e s . T h e c l i n i c a l evaluat i o n p r o c e s s can be s e p a r a t e d i n t o three areas: data gathering/recording, data interpretation, and clinical judgment. A clinical j u d g m e n t based on an adequate data base and w i t h corr e c t i n t e r p r e t a t i o n of c l i n i c a l d a t a can s t i l l be " w r o n g . " T h e p a t i e n t may have a bad outcome, even though the physician did all that was r e a s o n a b l y possible in t r e a t i n g and e v a l u a t i n g t h e p a t i e n t . C l a i m s resulting from this type of scenario do occur, and no m a t t e r how risk conscious and competent physicians m a y be, this type of case will still occur and, under the current tort system, will still result in a m a l p r a c t i c e claim. T h i s i r r e d u c i b l e c l a i m s incidence is u n k n o w n . 3 It is this type of c l a i m that m u s t be addressed by tort reform. Beyond this i n s t a n c e of bad outc o m e / g o o d care, an i n a d e q u a t e d a t a base and faulty i n t e r p r e t a t i o n of clinical data can produce a poor medical j u d g m e n t . It is these i n s t a n c e s t h a t the MACEP guidelines try to address. Trautlein's study demonstrated failure to p r o p e r l y e x a m i n e the patient in 41% of 200 claims. 3 The data f r o m o u r s t u d y suggest t h a t m a n y claims could have been prevented by applying very basic clinical principles. T h e MACEP guidelines consolidate and focus clinical data gathering and encourage appropriate d o c u m e n tation of w h a t was done by the physician. The care that was docum e n t e d in m a n y of t h e c l a i m s reviewed in our study was clearly insufficient. O n l y the ED record was reviewed because this medical record is the o n l y d o c u m e n t a t i o n m a d e at t h e t i m e of t h e e n c o u n t e r w i t h t h e patient; deposition statements; w h i l e they m a y be accurate, are colored by Annals of Emergency Medicine

t i m e a n d h i n d s i g h t . R u s n a k et al h a v e f o u n d t h a t d o c u m e n t a t i o n of h i s t o r i c a l i t e m s in i s c h e m i c c h e s t pain records were m o r e deficient in cases w h e r e e v e n t u a l c l a i m s w e r e filed t h a n in a c o n t r o l group w h e r e no litigation occurred.IS Studies l o o k i n g at the l i n k a g e of d o c u m e n t a t i o n w i t h q u a l i t y of care have yielded m i x e d results, although m o s t supported the positive correlation of the two. 16-t8 It is our p r e m i s e that if physicians are required to docu m e n t certain i t e m s on a medical record in order to c o m p l y w i t h guidelines for care and if certain incentives to c o m p l y w i t h g u i d e l i n e s such as m a l p r a c t i c e d i s c o u n t s are offered, physicians will perform the required d i a g n o s t i c i t e m s to a d h e r e to t h e guidelines and then d o c u m e n t their a d h e r e n c e to the g u i d e l i n e s as required to gain the e c o n o m i c i n c e n tive. t9 W h i l e a bad o u t c o m e resulting from a "wrong" clinical judgment based on an adequate data base and correct i n t e r p r e t a t i o n of clinical data can still result in a claim, d o c u m e n tation of the appropriate level of care should help protect the physician and decrease the eventual i n d e m n i t y dollars awarded. O n e s t u d y found significant diagn o s t i c errors occurring in p h y s i c i a n i n t e r p r e t a t i o n of a v a i l a b l e c l i n i c a l data. 2o In our study, inadequate comp i l a t i o n of a c o m p l e t e c l i n i c a l d a t a base was a far m o r e frequent p r o b l e m than faulty i n t e r p r e t a t i o n of a complete and careful clinical evaluation. D a t a i n t e r p r e t a t i o n d e f i c i e n c i e s do exist: errors in physician ECG readings have been shown to lead to inappropriate release of ED patients w i t h c h e s t pain. 21,22 We f o u n d t h a t s u c h data i n t e r p r e t a t i o n deficiencies were layered on inadequate data gathering 871/49

and recording. O u r judgment of prev e n t a b i l i t y of claims supposes that if a p r o c e d u r e w e r e done, eg, a pregn a n c y test, it w o u l d have resulted in a p p r o p r i a t e diagnosis and t r e a t m e n t of the clinical disorder and no claim w o u l d h a v e b e e n filed. W h i l e it is true that in s o m e u n k n o w n n u m b e r of these cases the " w r o n g " judgment m a y have resulted in a bad outcome, the c o m p l e t e n e s s of the record w o u l d h a v e m i t i g a t e d t h e i n d e m n i t y expense. Part of M A C E P ' s c o m m i t m e n t to risk m a n a g e m e n t is a two-clay course for e m e r g e n c y p h y s i c i a n s t h a t addresses h i g h - r i s k c l i n i c a l areas and introduces physicians to the MACEP guidelines. This educational program is d e s i g n e d to i n c r e a s e p h y s i c i a n awareness of p o t e n t i a l pitfalls in the e v a l u a t i o n of these high-risk areas in order to decrease physician data int e r p r e t a t i o n deficiencies as w e l l as i m p r o v e data g a t h e r i n g and recording. For example, one course lecture deals w i t h the s u b t l e t i e s of reading ECGs. O t h e r s cover i n d i c a t i o n s for and l i m i t a t i o n s of diagnostic imaging and i s s u e s of m e d i c a l d o c u m e n t a tion. Physicians participating in the two-day course should learn the imp o r t a n c e of data g a t h e r i n g / r e c o r d i n g and interpretation, and by participation in course d i s c u s s i o n s and case reviews m a y also i m p r o v e their subsequent clinical judgment. T h e course m a t e r i a l and M A C E P guidelines will change w i t h the evol u t i o n of m e d i c a l p r a c t i c e and n e w trends in m a l p r a c t i c e claims and tort law.

In 1989, M A C E P p e t i t i o n e d t h e Massachusetts Insurance Commissioner to grant a m a l p r a c t i c e insura n c e r a t e r e d u c t i o n to e m e r g e n c y physicians who participate in MACEP's risk m a n a g e m e n t program. T h e s e p h y s i c i a n s m u s t c o n s e n t to p a r t i c i p a t e in t h e t w o - d a y M A C E P course on risk m a n a g e m e n t , acquire ten Category I continuing medical education credits yearly in the area of risk management, demonstrate a p a s s i n g grade on p o s t - t e s t s at t h e s e e d u c a t i o n a l programs, and agree to ongoing audit of their ED records to ensure c o m p l i a n c e w i t h the MACEP g u i d e l i n e s for care in the h i g h - r i s k c l i n i c a l areas. T h e r e are n u m e r o u s i t e m s that could be audited in each diagnostic category; even w i t h comp u t e r i z e d record audits, this w o u l d be a logistic impossibility. 50/872

D e c i d i n g h o w to score the inclusion or exclusion of certain i t e m s is also dauntingly complex. MACEP has decided to audit guideline comp l i a n c e by t r a c k i n g critical a c t i o n s for each guideline that m u s t be noted in the clinical record. For example, in the epiglottitis guideline, the physician m u s t d o c u m e n t the p a t e n c y of the airway in every patient presenting w i t h a sore throat. Discharge ins t r u c t i o n s are a c r i t i c a l a c t i o n for each of the eight high-risk diagnostic areas. T h e y were often sketchy or absent in our claims study and are of significant medicolegal importance.23, 24 I n F e b r u a r y 1990, t h e M a s s a chusetts Insurance Commissioner ruled favorably on the MACEP petit i o n , g r a n t i n g a 20% d i s c o u n t on m a l p r a c t i c e p r e m i u m s to emergency p h y s i c i a n s p a r t i c i p a t i n g in this program. W h i l e the results of this closed claims study Were part of the M A C E P t e s t i m o n y p r e s e n t e d at the hearings, t h e d i s c o u n t was in large part granted due to the stringent aud i t i n g r e q u i r e m e n t s of the MACEP program. T h e r e is p r e c e d e n t i n M a s s a c h u s e t t s for a m a l p r a c t i c e d i s c o u n t program. In 1987, a n e s t h e s i o l o g i s t s who agreed to use intraoperative oxi m e t r y and c a p n o g r a p h y r e c e i v e d a m a l p r a c t i c e p r e m i u m d i s c o u n t . In the group using this technology, t h e r e h a v e b e e n no c l a i m s f i l e d against participating anesthesiologists for hypoxic brain damage since t h e p r o g r a m began.25, 26 As of July 1989, p a r t i c i p a t i n g a n e s t h e s i o l o g i s t s were downgraded from a Class V to Class IV risk rating; as of July 1990, t h e y w i l l be f u r t h e r d o w n g r a d e d to Class III. CONCLUSION T h e i n c i d e n c e of m a l p r a c t i c e claims n a t i o n a l l y has declined from 1985 to 1987. 27 In 1989, St Paul, the largest m a l p r a c t i c e insurance carrier in the U n i t e d States, a n n o u n c e d that it was c u t t i n g rates for physicians by 14%.

agement programs for physicians should still result in an appreciable decrease in the n u m b e r of claims and dollars paid. W h i l e w e h a v e c o n c e n t r a t e d on e c o n o m i c savings, unquantifiable imp r o v e m e n t in t h e q u a l i t y of e m e r gency care is also a very real benefit of such a risk m a n a g e m e n t program.
