Overutilization of antenatal care in Norway.

BACKGROUND: It has long been a common belief in Norway that all pregnant women attend antenatal care, but no documentation has been provided. In 1984, official guidelines were issued recommending a reduction of the number of routine visits. However, no studies have been performed in order to monitor whether the recommendations are followed. AIMS: Utilization review of antenatal care in Norway. METHOD: A national cross-sectional study, comprising all deliveries in all obstetrical units in the country during a two-week registration period in June 1996. Information on onset of antenatal care, the number of visits, parity and gestational age at the time of delivery was collected. The study comprised 1,557 deliveries; 45 of the 60 obstetrical units in the country participated. RESULTS: The mean number of antenatal visits was 12.2. Only two of the 1,557 women (0.1%) delivered without any previous antenatal care. A total of 80% started antenatal care in the first trimester, 0.4% had their first antenatal visit in the third trimester. The mean number of antenatal visits was substantially higher than the recommended number. CONCLUSION: Antenatal care-providers do not comply with the official guidelines.

Changes in related drug class utilization after market withdrawal of cisapride.

BACKGROUND: Recent Food and Drug Administration-mandated and company-initiated withdrawals of drug products from the marketplace have had an impact on utilization in related drug classes. OBJECTIVE: To investigate the impact of withdrawal of the prokinetic agent cisapride (Propulsid) on utilization of other gastrointestinal (GI) agents. STUDY DESIGN: A longitudinal, retrospective study using electronic prescription data from a state-funded geriatric prescription benefit program. PATIENTS AND METHODS: Prescription claims for 2644 patients using cisapride between January 10, 2000, and October 1, 2000, were analyzed with respect to points in time at which (1) prospective drug utilization review edits were implemented denying reimbursement of cisapride because of drug interactions, (2) the manufacturer announced its intent to cease production, and (3) the agent was withdrawn from the market. Prevalence of use, claims volume, and expenditures were compared for cisapride, proton pump inhibitors, histamine-2 receptor antagonists, and the prokinetic agent metoclopramide during these periods. RESULTS: Use of cisapride decreased precipitately even before implementation of a "medical exception only" reimbursement policy. After the change in policy, metoclopramide use increased, although this increase was not proportional to cisapride's decline. Although total GI expenditures declined within the cisapride cohort, this change had little impact on overall program GI expenditures. CONCLUSIONS: The loss of cisapride did not significantly affect program-wide costs for GI drugs. However, the withdrawal of cisapride appears to have resulted in increased use of metoclopramide, a medication with a more serious adverse effect profile than cisapride. Further study is needed to evaluate the long-term clinical impact of such therapy changes.

On-line DUR messages: pharmacists' attitudes and actions in response.

Community pharmacists are encountering on-line drug utilization review (DUR) messages with increasing frequency. DUR messages are sent by third party claims processors and generated by pharmacies' in-house computer systems. The purpose of this study was to ascertain community pharmacists' attitudes toward on-line DUR messages and the actions most often taken by pharmacists after receiving these messages. A 28-item questionnaire was mailed to a random sample of 1,500 community pharmacies throughout the United States. Four hundred twenty-seven questionnaires were returned and analyzed (a 28.5% response rate). The majority of respondents were male pharmacists practicing in independent community pharmacies in cities with populations of less than 50,000. The low response rate from chain pharmacies was an important limitation of this study. The results indicate that pharmacists find DUR messages related to medication overuse and drug interactions to be the most useful. Interventions are not performed for all DUR messages received, and interventions usually consist of telephoning physicians and talking to patients. This study demonstrates that many types of DUR messages are useful to pharmacists; however, additional research and further refinement of DUR messages appear necessary.

Evaluation of vancomycin use in a large university-affiliated hospital in eastern France in 1999.

OBJECTIVE: In 1999, we conducted a retrospective drug utilization review to determine the volume and pattern of vancomycin use in a university-affiliated hospital in eastern France. METHODS: Total vancomycin use was determined and expressed as vancomycin courses per 100 admitted patients and defined daily doses (DDD) of vancomycin per 100 patient-days. The indication for vancomycin use was classified as appropriate or inappropriate according to the guidelines issues by the HICPAC. RESULTS: A total of 311 vancomycin courses were given, as 2098 DDD, giving crude incidences of 1.17 courses per 100 admitted patients and of 1.19 defined daily doses per 100 patient-days. The frequency of appropriate courses was 66.7%. Of the 63 inappropriate courses of vancomycin, 39.7% and 28.6% were empiric therapy for nosocomial and community-acquired infections, respectively, 20.6% and 6.3% were specific therapy for nosocomial and community-acquired infections, respectively, and 4.7% were prophylactic. CONCLUSIONS: This study shows that vancomycin use in our hospital resulted in a lower selection pressure than has been reported for US university-affiliated hospitals and that comprehensive programs to improve use of vancomycin are needed in our institution.

Issues in mental health care benefits: the costs of mental health parity.

This Issue Brief discusses issues in mental health care benefits. It describes the current state of employment-based mental health benefits and discusses studies and issues regarding full mental health parity. It also includes an analysis of the effect of full mental parity on the uninsured population and the effects of the limited mental health parity provision contained in the VA-HUD appropriations bill. The final section discusses the implications of mental health parity for health plans and health insurers. When employers began to provide health insurance benefits to their employees and their families, they extended coverage to include mental health benefits under the same terms as other health care services. Many employers continued to add mental health benefits through the 1970s and early 1980s until cost pressures required employers to re-examine all health care benefits that were offered. They quickly found that, while only a small proportion of the beneficiaries used mental health care services, the costs associated with this care were very high. As a result, employers placed limits on mental health benefits in an attempt to make the insurance risk more manageable. The general strategies employers have used to manage their health care costs are cost sharing, utilization review, managed care, and the packaging of provider services. Employers' cost management strategies may be restricted, however. Five states have mental health parity laws, but three of the states--Rhode Island, Maine, and New Hampshire--apply these laws only to the seriously mentally ill. In addition, 31 states mandate that mental health benefits be provided. However, state mandates apply only to insured plans, not to self-insured employer plans, which are exempt from state regulation of health plans under the Employee Retirement Income Security Act of 1974 (ERISA). A number of recent studies have examined the effect of mental health parity on health insurance premiums in a "typical" preferred provider organization and on the uninsured. In general, the studies concluded that mental health parity could increase health insurance premiums, decrease health insurance coverage for non-mental health related illnesses, and increase the number of uninsured individuals. All studies of mental health parity, and mandated benefits in general, assume that there is a strong likelihood that increased health benefit costs would be passed along to workers in the form of higher cost sharing for health insurance, lower wage growth, or lower growth in other employee benefits.

Assessing physician choice of nonsteroidal antiinflammatory drugs in a health maintenance organization.

OBJECTIVE: To develop a categorization scheme for grouping various nonsteroidal antiinflammatory drugs (NSAIDs) by relative safety; to develop a method to quantify the appropriateness of the initial and subsequent choices of NSAID therapy; to assess whether NSAID prescribing was consistent with the developed criteria; to examine the cost of inappropriate, acute NSAID use as defined by the established criteria. DESIGN: Retrospective drug utilization review focusing on NSAIDs. SETTING/PARTICIPANTS: Members aged > or = 18 years of a 40,000-person southeastern Michigan health maintenance organization. MAIN OUTCOME MEASURES: (1) Appropriateness of therapy using a four-level safety classification system for the NSAIDs developed by a consensus process; criteria based on safety under the assumption that any particular NSAID is equally likely to be effective when dosed appropriately; (2) evaluation of progression of NSAID therapy using the NSAID Therapy Progression Formula. RESULTS: For acute patients, almost half of the prescriptions were for ibuprofen and 33 percent were for naproxen. Ibuprofen usage accounted for 16 percent of total NSAID cost and naproxen agents accounted for over 50 percent of that cost. Potential cost savings of approximately $82,000 probably would have occurred had a 50 percent interchange rate for ibuprofen been acceptable. For chronic patients, 85 percent were treated with one or two NSAIDs; treatments were of reasonable high quality when compared by safety profiles. There was low use of ibuprofen in patients who only received one NSAID. CONCLUSIONS: NSAID usage assessment in a large population was achieved by developing a classification and scoring system based on NSAID safety; in this population, prescribing patterns were generally consistent with established criteria; however, when considering cost, improvement in initial NSAID selection for acute patients was possible.

Evaluation of physician intervention letters.

OBJECTIVES: The Omnibus Budget Reconciliation Act of 1990 requires that Medicaid Agencies perform drug utilization review (DUR). The Texas Medicaid Agency, in cooperation with the Texas DUR Board, have chosen to mail intervention letters to physicians with patient profiles that indicate possible inappropriate use of medications. The objective of this study was to assess the effect of intervention letters indicating duplicative anti-ulcer medications. METHODS: Analysis of Medicaid prescription claims produced 335 patient profiles involving concurrent therapy. Physicians for 174 patients were selected randomly to receive an intervention letter, a response form, and a stamped envelope. The remaining patients served as a control group. RESULTS: A 71.2% response rate was obtained. Of these responses, 48.9% agreed with the letter and 19.1% disagreed with the letter. Profiles generated 6 months after the letters were sent indicated that 47.7% of the patients in the experimental group were still on concurrent therapy compared with 64.4% of patients in the control group (P = 0.007). CONCLUSIONS: The high response rate to the letter, the moderately high agreement with the letters, and the statistically significant reduction of duplicative therapy in the experimental group indicate that intervention letters can be an effective way to change prescribing. Future research is needed to assess the effects of educational intervention letters for other drug categories, for other populations, and for longer periods of time; and the effect these changes may have on true patient outcomes.

Use of systemic anti-infective agents in Iran during 1997-1998.

OBJECTIVE: Conduction of standardized national drug utilization review to investigate the pattern of systemic anti-infective agent use in Iran. METHODS: The wholesale data were used. The Anatomical Therapeutic Chemical (ATC) classification and the defined daily dose (DDD) methodology was employed. Data were presented as DDD/1,000 inhabitants"day. Results were compared using national drug statistics of Norway, Sweden, and Denmark. RESULTS: The overall sales of systemic anti-infective agents was 43.5 DDD/1,000 inhabitants/day. The parenteral form of drug accounted for 4.20% and broad-spectrum systemic antibacterial agents accounted for 86.2%. The three most commonly used agents, accounting for 74.1% of total sales, were amoxicillin, co-trimoxazole, and ampicillin. Seven kinds of anti-infective agents (17% of total available agents) accounted for 90% of antibacterial use, with dominance of broad-spectrum agents. Comparison showed differences in pattern and intensity of use. The sales of systemic anti-infective agents in general, particularly antibacterials and anti-tuberclotics, were greater in Iran than in three European countries. Broad-spectrum antibacterial agents accounted for a larger proportion of total sales in Iran. CONCLUSION: The high use of systemic antibacterial agents in general, particularly broad-spectrum agents, suggest the possibility of irrational prescribing, higher prescribed daily doses than DDDs, and a drug wastage. This survey, as a first attempt, provided an overview of anti-infective use in Iran. Thus, it may serve as a basis for further investigative studies and advanced drug policies.

A controlled letter intervention to change prescribing behavior: results of a dual-targeted approach.

OBJECTIVE: To determine the effectiveness of a drug utilization review (DUR) letter intervention sent only to physicians, sent only to pharmacists, or sent to both physicians and pharmacists in changing physician prescribing behavior for dipyridamole. DATA SOURCES/STUDY SETTING: A Wisconsin Medicaid prescription drug database for data from March 1991 through May 1992 related to both long-term care and ambulatory patient settings. STUDY DESIGN: The effects of a DUR letter intervention were tested using a field study, pre-post, nonequivalent control group, quasi-experimental design. The effects of the letter intervention in terms of dipyridamole expenditures (dollars reimbursed to pharmacies by Medicaid), expenditures for related drugs (aspirin, ticlopidine, sulfinpyrazone) and numbers of patients for whom dipyridamole was discontinued were examined across three experimental groups and a control group. DATA COLLECTION/EXTRACTION METHODS: Dipyridamole expenditures for each study patient during a six-month preintervention and six-month postintervention period were collected from Medicaid prescription drug claims. Patients who had zero dipyridamole expenditures throughout the six-month postintervention period were classified as having had dipyridamole discontinued. PRINCIPAL FINDINGS: Letters sent to both physicians and pharmacists resulted in a greater percentage of patients discontinuing dipyridamole relative to controls and statistically significant differences in postintervention dipyridamole expenditures relative to controls in both the long-term care and ambulatory patient populations. CONCLUSIONS: Interventions that focus on another person in the drug use process in addition to the physician may have greater effects on a change in the prescribing of a targeted drug than letters to physicians alone.

Impact of inappropriate drug use on mortality and functional status in representative community dwelling elders.

BACKGROUND: The predictive validity of Drug Utilization Review (DUR) and drugs-to-avoid criteria in elders is unknown. OBJECTIVES: To evaluate the relationship between use of inappropriate drugs as determined by these explicit criteria and mortality and decline in functional status in community dwelling elders. RESEARCH DESIGN: Cohort study. SUBJECTS: The fourth wave (3234 participants) of the Duke Established Populations for Epidemiologic Studies of the Elderly. MEASURES: Two sets of inappropriate drug-use criteria: (1) DUR with respect to dosage, duplication, drug-drug interactions, duration, and drug-disease interactions; and (2) Beers-modified criteria regarding drugs-to-avoid were applied to drug use reported in an in-home interview. Death was identified from the National Death Index; change in four functional status measures (basic self-care, intermediate self-care, complex self-management, physical function) was determined during the following 3 years. RESULTS: Use of inappropriate drugs identified by either set of criteria was not significantly associated with mortality. The drugs-to-avoid criteria identified no significant associations between use of these drugs and decline in functional status. With DUR criteria, however, the association between use of inappropriate drugs and basic self-care was significant and pronounced among those with drug-drug or drug-disease interaction problems (Adj. OR 2.04; 95% CI 1.32-3.16). CONCLUSIONS: Identifying the impact of inappropriate drug use may depend on the criteria applied. Further studies are needed that measure additional outcomes and use alternate measures of inappropriate drug use.

Impact of an educational intervention for secondary prevention of myocardial infarction on Medicaid drug use and cost.

OBJECTIVES: The objectives of this drug utilization review program were (1) to increase beta-blocker prescribing to fee-for-service post-acute myocardial infarction (AMI) Medicaid patients; (2) to improve compliance among patients who were prescribed beta-blockers post-AMI; and (3) to evaluate the economic implications of increased beta-blocker prescribing. STUDY DESIGN: Pre-post nonequivalent group design. PATIENTS AND METHODS: The intervention targeted physicians of Pennsylvania Medicaid recipients who had an AMI between November 1, 1998, and November 1, 1999. Educational materials were sent to the physicians of post-AMI patients not receiving beta-blockers. Preintervention and postintervention rates of beta-blocker prescribing in the Medicaid program within 7 and 30 days of discharge after an AMI hospitalization were compared. Similarly, pre- and postintervention compliance rates were compared for AMI patients who were prescribed beta-blockers. Cost savings and number of avoided deaths also were calculated. RESULTS: There was a 5.5%, to 6.9% increase in beta-blocker prescribing after the intervention, depending on the follow-up period. Postintervention AMI patients were 16% more likely to be prescribed a beta-blocker. There was an 8.3% increase in patient compliance with beta-blocker therapy from preintervention to postintervention. In the first 2 years of the intervention, the estimated cost savings to the Pennsylvania Medicaid program ranged from 71,970 dollars to 76,678 dollars, respectively. An estimated 3 deaths were avoided. CONCLUSIONS: The intervention resulted in increased appropriate prescribing and compliance with beta-blockers among post-AMI patients. There also were estimated cost savings to Pennsylvania Medicaid as a result of reduced hospitalization, and fewer deaths.

The impact of managed care on psychiatry.

It is estimated that 50% of all practicing psychiatrists have at least one contract with a managed care organization (AMA, 1994). As the field of psychiatry increasingly adopts the tools of managed care, it is important for researchers to clarify the extent to which managed care affects the practice of psychiatry, and how the changing practice climate in turn affects patients seeking mental health care. A diverse array of managed care techniques have been introduced into the profession of psychiatry in an effort to alter treatment patterns. One commonly used tool, utilization review, can alter treatment patterns by restricting access to treatment alternatives and providing incentives to practitioners to meet managed care goals. Other managed care tools are the determination of "medical necessity" and the use of triage and treatment guidelines among insured enrollees requesting services. These guidelines serve as selection criteria to help determine not only which members of the insured population receive treatment for mental health care, but also to determine the allocation of enrollees to staff members and to prescribe the starting point for the types of services received. Managed care psychiatrists may find changes not only in their client populations and treatment alternatives, but in many other aspects of their practice. Some psychiatrists working in managed care have become increasingly involved in treatment teams. Other psychiatrists contracting with MCOs are reserved for medication management, consultation, or administration in carved-out mental health departments or agencies. Little is known about the extent to which managed care restrictions affect psychiatrists' patient care roles, collaborative relationships with other mental health professionals, and the degree to which psychiatrists are involved in administration of managed mental health care benefits. The era of managed care has constrained the clinical decision making of psychiatrists whose magnitude and impact on job satisfaction and labor market responses are unknown. Surveys of general physicians in MCOs have provided a framework for understanding some of the difficulties and opportunities faced by managed care psychiatrists, but have failed to shed much light on many aspects of medical practice specific to the provision of mental health care within the boundaries of managed care. Future research in this area would help fill this gap, and assist in shaping the roles of psychiatrists in managed mental health care organizations.

Impact of inappropriate drug use on health services utilization among representative older community-dwelling residents.

BACKGROUND: There is limited objective information regarding the impact of drugs identified as inappropriate by drug utilization review (DUR) or the Beers drugs-to-avoid criteria on health service use. OBJECTIVE: The goal of this study was to examine the predictive validity of DUR and the Beers criteria employed to define inappropriate drug use in representative community residents, aged >or=68 years, as determined by the relationship of these criteria to health service use in older community residents. METHODS: Data came from participants in the Duke University Established Populations for Epidemiologic Studies of the Elderly seen in 1989/1990 and for whom information was also available 3 years later. Two sets of inappropriate drug use criteria were examined: (1) DUR regarding dosage, duration, duplication, and drug-drug and drug-disease interactions; and (2) the Beers criteria, applied to drug use reported in an in-home interview. Outpatient visits and nursing-home entry were determined by personal report; hospitalization information came from Medicare Part A files from the Centers for Medicare and Medicaid Services. RESULTS: A total of 3165 participants were available at the fourth interview in 1989/1990. The majority were aged >74 years (51.1%), white (64.8%), women (64.7%), had fair or poor health (77.0%), consistently saw the same physician (86.9%), and possessed supplemental health insurance (62.8%). Use of inappropriate drugs meeting DUR criteria, especially for drug-drug or drug-disease interaction problems, was associated with increased outpatient visits (P<0.05) but not with time to hospitalization or time to nursing home entry. The use of inappropriate drugs according to the Beers criteria was associated with reduced time to hospitalization (adjusted hazard ratio, 1.20; 95% CI, 1.04-1.39) but not to outpatient visits or nursing home entry. CONCLUSIONS: Our data suggest that in representative community residents aged >or=68 years, current criteria for inappropriate drug use should be used with caution in evaluating quality of care because they have minimal impact on use of health services. We found increases only in the use of outpatient services (with DUR) and more rapid use of hospitalization (with the Beers criteria).

Preparing residents for managed care practice using an experience-based curriculum.

Many U.S. residency graduates will practice in various types of managed care organizations, where they will be expected to arrive skilled in managed care activities such as prescribing with formularies and adhering to preauthorization processes for procedures, referrals, and hospital admissions. Residency programs must prepare their trainees to negotiate for their patients' needs within such systems. This article describes a University of California, Los Angeles, UCLA School of Medicine curriculum that teaches managed care skills to residents in two internal medicine residency training programs. The residents in one program participate in a commercial health maintenance organization plan via a group-model faculty practice. Managed care activities for residents in this program were gradually introduced beginning in 1990. This reflected previous years' gradual yet enforced introduction of managed care activities that occurred for this program's faculty and most group practice physicians in California. Residents in the other program train at a public hospital where managed care practice is simulated. Managed care activities were not required by this program's institution but were voluntarily introduced for their educational value beginning in 1994. Responding to this program's trainee and faculty requests, these activities were rapidly implemented over two years with the goal of preparing residents for joining practices in a market with high managed care penetration. Since 1994, the centerpiece of the curriculum has been residents' participation in ambulatory utilization review and related activities. Residents learn managed care principles through problem-based learning, experiential exercises, and feedback on resource utilization. The curriculum has affected residents' attitudes toward managed care and changed their patterns of referrals and resource use. Residents trained with this curriculum perceive managed care practices as familiar and less intrusive. They submit fewer requests for referrals, perhaps with review in mind. However, precautions may be required to avoid undercare. The authors found that the reduction of referrals requested was greater than what they had expected. Residents may find scrutiny by colleagues intimidating. Also, this curriculum requires a substantial time commitment from residency training, with its already busy teaching agenda. The authors feel that initiating a managed care curriculum is an important investment in time for U.S. residency programs. Given that most graduates of residency programs will have their health care management decisions scrutinized while in practice, the authors feel it is important that residents' first exposure to managed care be while they are still in the supportive residency environment. They believe that early exposure will not only give residents the confidence to overcome the intimidation of colleague scrutiny, but may also give graduates the tools for involvement with the development of future managed care health policy.

Tools for post LEEP surveillance.

UNLABELLED: Recurrences of cervical intraepithelial neoplasia (CIN) as well as invasive cervical carcinoma have been reported to arise following ablative or excisional treatment for cervical intraepithelial neoplasia. This review utilizes MEDLINE and National Library of Medicine's PubMed review of the various screening tools used in follow-up protocols for women treated by loop excision for CIN. Cervical cytology, colposcopy, endocervical curettage and HPV typing have been advocated for use as tools for follow up. Involvement of the surgical margins and the presence of HPV-DNA are associated with higher risks of recurrence and should be taken into consideration. The psychological impact of undergoing colposcopy may affect compliance with follow-up visits and should be dealt with appropriately. LEARNING OBJECTIVES: After completion of this article, the reader should be able to list the various tools that can be used for the surveillance of patients after treatment for CIN, to compare the advantages and disadvantages of each surveillance method, and summarize methods to improve compliance with follow-up.

Role of adhesiolysis in the management of chronic spinal pain: a systematic review of effectiveness and complications.

BACKGROUND: Percutaneous epidural adhesiolysis and spinal endoscopic adhesiolysis are interventional pain management techniques that play an active role in managing chronic intractable low back pain. There have not been any systematic reviews performed on this subject. OBJECTIVE: To evaluate the effect of percutaneous adhesiolysis and spinal endoscopic adhesiolysis in managing chronic low back and lower extremity pain. STUDY DESIGN: A systematic review utilizing the methodologic quality criteria of the Cochrane Musculoskeletal Review Group for randomized trials and the criteria established by the Agency for Healthcare Research and Quality (AHRQ) for evaluation of randomized and non-randomized trials. METHODS: Search identified the relevant literature, through searches of MEDLINE and EMBASE (January 1966 to November 2004), BioMed Central and Cochrane Review database. Manual searches of bibliographies of known primary and review articles, and abstracts from scientific meetings within the last 2 years, in English language. Randomized and non-randomized studies were included in the review based on the criteria established. Three reviewers independently assessed the trials for the quality of their methods. Percutaneous adhesiolysis and endoscopic adhesiolysis were analyzed separately. OUTCOME MEASURES: Primary outcome measure was significant pain relief (50% or greater). Other outcome measures were functional improvement, improvement of psychological status, and return to work. Short-term relief was defined as less than 3 months, and long-term relief was defined as 3 months or longer. RESULTS: There was strong evidence to indicate effectiveness of percutaneous epidural adhesiolysis with administration of epidural steroids for short term and long term in chronic, refractory low back pain and radicular pain. There was moderate evidence of effectiveness of addition of hypertonic saline. The evidence of effectiveness of hyaluronidase was negative. There was strong evidence to indicate effectiveness of spinal endoscopic adhesiolysis and epidural steroid administration for short-term improvement, and moderate evidence for long-term improvement in managing chronic, refractory, low back and lower extremity pain. CONCLUSION: The evidence of effectiveness of percutaneous adhesiolysis with administration of hypertonic sodium chloride administration, and spinal endoscopic adhesiolysis with epidural steroid administration in managing chronic, refractory low back and lower extremity pain of post lumbar laminectomy syndrome or epidural fibrosis was moderate to strong.

Cefoxitin use review.

Due to an increase in cefoxitin use at The Mississauga Hospital, a Drug Utilization Review (DUR) was conducted as part of the DUR program. The study was designed to determine the cefoxitin prescribing pattern, assess the appropriateness of use, calculate the cost associated with inappropriate use, and estimate future potential cost savings. Two evaluators (pharmacist and infectious disease specialist), reviewed cefoxitin use retrospectively during a four-month period for 82 patients who received a total of 100 courses of therapy. The appropriateness of cefoxitin use was assessed according to the predefined criteria that were developed and accepted by the hospital pharmacy, infectious disease and medical staff. Cefoxitin was prescribed more frequently by the department of surgery (45%) of the courses studied, while the medical and obstetric and gynecology services were responsible for the remainder of courses (24% and 31% respectively). Overall, 42% of the courses were deemed inappropriate and 11% were questionable, based on the choice of agent (62%) and the duration of treatment and prophylaxis (33%). The observed inappropriate use represented 22% of the amount spent on the total cefoxitin treatment of the 82 study patients. If cefoxitin had been prescribed appropriately, an estimated $11,873 could potentially have been saved annually by the hospital. Based on these results, recommendations for improving the quality and quantity of cefoxitin use were developed. Follow-up concurrent DUR's with pharmacist interventions were initiated and found to be cost-effective.
