Purpose. Educational interventions to

re-duce the use of abbreviations and dosage designations that were deemed unsafe at a level 1 trauma center are described.

Summary. Strategies to reduce the use of

unsafe abbreviations at Detroit Receiving Hospital were studied. Six abbreviations and dosage designations were deemed as unsafe by the site’s medication-use and patient medical safety committees: (1) U for units, (2) µg for microgram, (3) TIW for three times a week, (4) the degree symbol for hour, (5) trailing zeros after a decimal point, and (6) the lack of leading zeros be-fore a decimal point. Data on abbreviation use was collected starting in September 2003 by examining copies of patients’ order sheets, which are sent from nursing units to the pharmacy for processing. Data were collected during three 24-hour periods each month, with 7–10 days between each period. A data collection sheet was devel-oped to assist in documenting the number of opportunities for each unsafe abbre-viation and the actual incidence of each.

Educational strategies were developed and implemented starting in October 2003 to decrease the use of the unsafe abbrevia-tions. These strategies included inservice education programs for the medical, phar-macy, and nursing staffs; laminated pocket cards; patient chart dividers; stickers; and interventions by pharmacists and nurses during medication prescribing. During the eight-month evaluation period, 20,160 orders were reviewed, representing 27,663 opportunities to use a designated unsafe abbreviation. Educational interventions successfully reduced the overall incidence of unsafe abbreviations from 19.69% to 3.31%.

Conclusion. Educational interventions

markedly reduced the use of unsafe ab-breviations in medication orders over an eight-month evaluation period.

T

he use of abbreviations and

dos-age designations in medication prescribing has received much attention recently and has become a national concern as one of the ma-jor causes of medication errors.1-3

The use of abbreviations is a long-standing practice among health care practitioners, and these shortcuts often appear in order forms, stand-ing protocols, and policies.4 However,

some abbreviations may be misin-terpreted, leading to medication errors. The risk of misinterpreting an abbreviation is even greater with handwritten orders, as the handwrit-ing may be illegible.4

The idea of eliminating the use of abbreviations is not new. For exam-ple, the Institute for Safe Medication Practices has expressed this sentiment for 25 years, and the Joint Commis-sion on Accreditation of Healthcare Organizations (JCAHO) has man-dated that specific abbreviations not be used in clinical communica-tions.4-7 Many other organizations,

including the Institute of Medicine,

American Society of Health-System Pharmacists (ASHP), Food and Drug

Administration (FDA), National Co-ordinating Council for Medication

Error Reporting and Prevention, and American Hospital Association, warn that the use of inappropriate abbre-viations may lead to confusion and

communication failures.4-7

In July 2003, JCAHO created a new standard requiring institutions to identify six “unsafe” abbreviations which may not be used in clinical communication or documenta-tion, including medication orders. In November 2003, JCAHO revised this standard to include a specific list of abbreviations that it deemed unsafe and required institutions to identify an additional three abbrevia-tions that could not be used by April 2004.7

This article describes one institu-tion’s efforts to reduce the use of ab-breviations and dosage designations that were deemed unsafe.

Background. Detroit Receiving Hospital (DRH) is a 340-bed, level 1 trauma center located in downtown Detroit, Michigan. DRH is part of the Detroit Medical Center and serves as a training center for schools of medicine, nursing, and pharmacy. Approximately 50% of the physicians who practice in southeast Michigan have been trained at DRH.

In response to JCAHO’s initial mandate regarding unsafe abbre-viations, DRH’s medication-use and patient medical safety committees identified six unsafe abbreviations and dosage designations that were no longer to be used: (1) U for units, (2) µg for microgram, (3) TIW for three times a week, (4) the degree symbol for hour, (5) trailing zeros after a decimal point, and (6) the lack of leading zeros before a decimal point. (For simplicity, trailing and leading zeros, when used inappropriately, are called unsafe abbreviations in this article.)

Data collection on abbreviation use began in September 2003 by examining copies of patients’ order sheets, which are sent from nursing units to the pharmacy for process-ing. Data were collected during three

24-hour periods each month, with 7–10 days between each period. A data collection sheet was developed to assist in documenting the number of opportunities for each unsafe ab-breviation and the actual incidence of each. Opportunities were defined as the use of a designated unsafe ab-breviation or its safer alternative, and incidence was defined as the number of times an unsafe abbreviation was used divided by the number of op-portunities for its use. Since pharma-cists contacted prescribers when dis-allowed abbreviations were detected, the resulting rewritten orders were not counted as opportunities.

Interventions. After data collec-tion in September 2003, educacollec-tional strategies were developed and imple-mented starting in October 2003 to decrease the use of the unsafe ab-breviations. These strategies included inservice education programs for our medical, nursing, and pharmacy staff and contacting prescribers to clarify orders containing these abbreviations and explaining why they may not be

used. In addition, memorandums

and e-mails from DRH’s medical of-ficers were sent to all health care staff. Additional educational materials included pocket cards, medical chart dividers, and stickers.

The laminated pocket cards were two-sided. One side included notes about safe prescription-writing prac-tices and policies, and the other side provided a list of the designated un-safe abbreviations and their intended meanings, misinterpretations, and recommended safe alternatives.

The medical chart dividers con-tained the same information as the laminated pocket cards and were placed in all patients’ medical charts. These dividers separated medication and laboratory orders from the rest of the chart.

Stickers designed to look similar to traffic signs were used to iden-tify prohibited activities. Each sticker bore a specific prohibited abbrevia-tion surrounded by a large red circle

with a slash through it. These stick-ers could be worn on clothing (e.g., laboratory coats, shirts) and were distributed to staff to remind them to avoid the use of these abbreviations.

The results of these interventions were regularly reported to DRH’s medication-use (the site’s pharmacy and therapeutics committee) and patient medical safety commit-tees. Additional memorandums and e-mails were sent to staff when deemed necessary, based on the incidence of use of the identified abbreviations.

Experience. During the eight-month evaluation period, 20,160 orders were reviewed, representing 27,663 opportunities to use a desig-nated unsafe abbreviation. Baseline data were collected in September 2003, and the incidence of un-safe abbreviations was found to be 19.69% (Table 1). Initial staff educa-tion began the following month. In November 2003, the incidence of unsafe abbreviations declined to 16.56%, when pharmacists began contacting prescribers to clarify the intent of unsafe abbreviations. Use of unsafe abbreviations continued to decline over the following months, and at the end of our study period the overall incidence of unsafe ab-breviations was 3.31%.

The use of specific unsafe abbre-viations declined from baseline, with 100% compliance with JCAHO stan-dards (0% incidence) noted for three of them (Table 2). Investigation into why some prescribers failed to in-clude a leading zero before a decimal point revealed that this omission oc-curred most frequently in orders for i.v. 0.9% sodium chloride injection. Subsequent e-mails and memoran-dums sent in February 2004 alerted medical, pharmacy, and nursing staff to this problem. By April 2004, the lack of a leading zero had declined from 17.9%, which exceeded the baseline 12.8% incidence, to 3.2%.

Discussion. In November 2003, JCAHO revised its standards to in-clude a specific list of abbreviations

(3)

that it deemed unsafe. As a result, it required us to add additional breviations to our “do not use” ab-breviation list: qd, qod, MS, MSO4,

and MgSO4. In addition, it required

institutions to identify an additional three abbreviations that could not be used by April 2004. We started incorporating JCAHO’s revised list of unsafe abbreviations, which includes many of the abbreviations we initially identified, in our educa-tional process; but for the purpose of our evaluation, we limited our assessment to reduction in the use of the unsafe abbreviations initially identified by DRH.

The increasing number of prohib-ited abbreviations can make it dif-ficult for staff to remember them all. Therefore, it was important to keep the staff up to date on any changes in the program. Educational materials

were revised to reflect the new list of unsafe abbreviations. A screen saver containing the unsafe abbreviations, their intended meanings, com-mon misinterpretations, and recom-mended alternatives was added to all inhouse computers. In addition, inservice educational programs are planned to be presented to new resi-dents, staff, and students in medicine, pharmacy, and nursing schools.

Part of the education process involved notifying prescribers when they used an unsafe abbreviation/ dosage designation. When phar-macists encountered an order con-taining an unsafe abbreviation or dosage designation, they contacted the prescriber to clarify the order and, when necessary, obtained an oral order, which would be rewritten using a safer alternative. Beginning in July 2004, orders containing a

designated unsafe abbreviation or designation were no longer accepted, and the prescriber was required to rewrite the order. In other words, prescribers could no longer issue oral clarifications of orders containing these terms. Instead, the prescribers or the prescribers following their ser-vice (e.g., oncall physicians) had to rewrite the orders themselves.

According to a 2005 ASHP na-tional survey of pharmacy practice in hospitals, 52% of hospitals have achieved the JCAHO goal of elimi-nating the use of unsafe abbrevia-tions and dosage designaabbrevia-tions.8

Fac-tors that enhanced DRH’s successful elimination of unsafe abbreviations included medical staff support and pharmacy staff follow-up. Other institutions have also developed novel ways of bringing this issue of unsafe terminology to their staff and teaching them safer alternatives. One institution provided its staff with T-shirts with a list of the “good” abbreviations on one side and a list of the “bad” abbreviations on the other.9 While this strategy did not

eliminate the problem, it did result in some improvement.

The process of contacting pre-scribers when encountering unsafe abbreviations and dosage designa-tions can increase pharmacists’ workload and create the perception that they are the “abbreviation po-lice.” It is important to remind phar-macy staff that avoidance of these terms is important for improving patient safety and that this standard is not unique to one institution but is being implemented across the coun-try. The avoidance of these abbrevia-tions is the responsibility of all health care practitioners, and pharmacy is responsible only for following up on their use on medication orders. Oth-er departments will follow up on the use of these abbreviations in other documentation. Moreover, tracking the use of unsafe abbreviations is a part of the performance improve-ment process mandated by JCAHO.

There is no specific time limit in our institution to stop these efforts to re-duce the use of unsafe abbreviations and dosage designations.

Pharmacists must view the task of contacting prescribers when they encounter unsafe abbreviations as part of their everyday practice and no different from obtaining clarifica-tion of any other quesclarifica-tionable order. By treating it as such and routinely calling for clarifications, the use of these abbreviations should decline over time. Consequently, the number of follow-up calls required should decrease.

Resistance from the medical staff, while a reasonable concern, was not encountered in our institution. On the contrary, our medical staff lead-ership and hospital administration

have been very supportive of our efforts.

Conclusion. Educational inter-ventions markedly reduced the use of unsafe abbreviations in medication orders over an eight-month evalua-tion period.
