Decision analysis in the formulary process.

The use of decision analysis as a tool in making formulary decisions is discussed. Decision analysis is best applied in formulary decisions when factors other than acquisition costs are important in determining overall treatment costs for two products. The decision-analysis process assigns probabilities and costs to various treatments and outcomes. In the case of acute myocardial infarction, the decision analyst would gather data on angioplasty and thrombolysis and assign probabilities and costs for each treatment and subsequent endpoints on the basis of clinical trial data. When such data do not exist, estimates may be generated by expert panels. Applying clinical trial data to an individual hospital is not straightforward because of differences between clinical trials and clinical practice. Analysts and clinicians should evaluate any proposed model for its robustness and adaptability to local conditions and practitioner variation. Access to internal hospital data is essential in developing the model. An ideal decision-analysis model includes all important available interventions and defines and discloses the analyst's time frame and financial perspective. After implementation of the formulary decision, the results can be monitored and, if necessary, adjustments can be made in the allocation of resources. Barriers to effective decision analysis include lack of data and differences in sources of cost and outcome data. Despite the current limitations of decision analysis, clinicians and policymakers may find this technique increasingly useful in the complex formulary process.

Activities, functions, and structure of pharmacy and therapeutics committees in large teaching hospitals.

The results of a survey on the activities and functions of hospital-based pharmacy and therapeutics (P&T) committees are presented. Questionnaires were mailed to the pharmacy director or the person responsible for the pharmacy's drug information service at 267 teaching hospitals throughout the United States in 1994 and 1995. The survey questions covered P&T committee composition, functions, roles of members, policies and procedures, and formulary-maintenance activities. The overall response rate was 70%. The mean number of members on the P&T committees was 19.3, of whom 91% were allowed to vote. There was an average of 12.3 physicians on the committees. Each P&T committee had at least one pharmacist member, with an average of 3.2 pharmacist members; 69.5% of the institutions reported having a committee secretary, who was almost always a pharmacist. On almost all committees, pharmacists wrote the minutes, prepared the formulary review documents, and were responsible for monitoring formulary activities outside the meeting. The P&T committee functioned in a very formal manner. Most (87.7%) of the respondents reported that their institutions had a closed formulary. At all hospitals, the attending medical staff could request additions to the formulary, but at only 62.4% of the hospitals could pharmacy staff make a similar request. The committees were active in changing the formulary. P&T committees in large teaching hospitals are active in formulary management, are large and diverse, and consist mainly of physicians, although pharmacists play an important role in the meetings.

Approaches to drug therapy, formulary, and pathway management in a large community hospital.

Use of a clinical pathway for the management of community-acquired pneumonia (CAP) at a large community hospital is described. The pathway was developed and implemented by a multidisciplinary team. Fluoroquinolone therapeutic interchange and intravenous (i.v.) to oral (p.o.) conversion were part of the pathway; through literature review, levofloxacin was chosen as the preferred quinolone. Outcomes (length of stay [LOS] and readmission rates for pathway and nonpathway patients with CAP, economic impact of the fluoroquinolone interchange protocol, and resistance patterns) were evaluated. For pathway patients in 1998, LOS was 1.2 days shorter and the readmission rate was lower. Projected drug cost savings as a result of the fluoroquinolone interchange protocol were more than $22,000 annually. Pharmacists' interventions in antimicrobial prescribing for CAP patients can lead to cost efficiency and positively affect patient outcomes.

Pharmacy costs associated with nonformulary drug requests.

Pharmacy costs associated with handling nonformulary drug requests were studied. Data for all nonformulary drug orders received at a university hospital between August 1 and October 31, 1999, were evaluated to determine their outcome and the cost differential between the nonformulary drug and formulary alternative. Two sets of data were used to analyze medication costs: data from nonformulary medication request forms, which allowed the cost of nonformulary drugs and their formulary alternatives to be calculated, and data from the pharmacy computer system, which enabled actual nonformulary drug use to be captured. Labor costs associated with processing these requests were determined through time analysis, which included the potential for orders to be received at different times of the day and with different levels of technician and pharmacist support. Economic analysis revealed that the greatest cost saving occurred when converting nonformulary injectable products to formulary alternatives. Interventions were least costly during normal business hours, when all the satellite pharmacies were open and fully staffed. Pharmacists' interventions in oral product orders resulted in a net increase in expenditures. Incremental pharmacy costs associated with processing nonformulary medication requests in an inpatient setting are greater than the drug acquisition cost saving for most agents, particularly oral medications.

ASHP national survey of pharmacy practice in hospital settings: prescribing and transcribing--2001.

Results of the 2001 ASHP national survey of pharmacy practice in hospital settings that pertain to prescribing and transcribing are presented. A stratified random sample of pharmacy directors at 1091 general and children's medical-surgical hospitals in the United States was surveyed by mail. SMG Marketing Group, Inc., supplied data on hospital characteristics; the survey sample was drawn from SMG's hospital database. The response rate was 49.0%. During 2001, nearly all hospitals are estimated to have pharmacy and therapeutics (P&T) committees that meet an average of seven times per year. It is estimated that more than 90% of P&T committees are responsible for formulary development and management, drug policy development, adverse-drug-reaction review, and medication-use evaluation. More than 90% of hospitals use clinical and therapeutic, cost, and pharmacoeconomic information in the formulary management process, while nearly two thirds consider quality-of-life issues. Nearly 70% use clinical practice guidelines in the formulary management process, and 78% have a medication-use evaluation program designed to improve prescribing. Pharmacists in more than 75% of hospitals provide consultations on drug information, dosage adjustments for patients with renal impairment, antimicrobials, and pharmacokinetics. Further, a majority of hospitals ensure accurate transcription of medication orders by clarifying illegible orders before transcription or entry into medication administration records (MARs), using standardized prescriber order forms, requiring prescribers to countersign all oral orders, and reconciling MARs and pharmacy patient profiles at least daily. In 2001, large hospitals are most likely to use prescriber order-entry systems to improve patient safety and are least likely to require the reentry of medication orders into the pharmacy computer system. The 2001 ASHP survey results suggest that pharmacists in hospital settings have positioned themselves well to improve the prescribing and transcribing components of the medication-use process.

Use of pharmacoeconomic data in making hospital formulary decisions.

The use of pharmacoeconomic data in hospital formulary decisions was explored. Data were collected from pharmacist members of pharmacy and therapeutics (P&T) committees in 204 Florida hospitals. Participants were asked, via a cross-sectional telephone survey, to rate 10 factors used in making formulary decisions from 1 (most important) to 10 (least important). Participants were also asked about the usual sources of pharmacoeconomic data used by the P&T committee, the types of pharmacoeconomic analyses and humanistic outcome measures that have been used by the P&T committee to make formulary decisions, and the availability of someone with pharmacoeconomic skills to assist with the formulary decision-making. The average time spent collecting data was 19 minutes. Data were analyzed using descriptive statistics and correlation analysis. Eighty-six percent of the participants indicated that pharmacoeconomic data were used all the time or very often when formulary decisions were made, with only 6% stating that these data were rarely or never used. Pharmacoeconomic data were rated by 63% of participants to be very important in formulary decisions. The usual sources of pharmacoeconomic data listed by participants are inhouse data (75%), published literature (57%), and pharmaceutical industry studies (13%). Participants rated drug efficacy, toxicity, and side effects as the most important and avoiding use of home infusions as the least important factors in making hospital formulary decisions. About 70% of the hospitals had someone with pharmacoeconomic skills on staff, while 4% reported consulting with an external pharmacoeconomics expert. Most P&T committees in Florida hospitals relied on pharmacoeconomic data to assist them in making formulary decisions.

Building a better online formulary.

The history of and improvements made to the University of Michigan Health System (UMHS) inpatient online formulary are described. The current formulary at UMHS is the third version of the Web-based formulary. The original effort in 1997 consisted of converting word-processing documents to HTML format and exporting this information to the university's intranet. There was no mechanism to search for formulary items, no therapeutic class cross-referencing, and no cost information. Documents and their conversion had to be manually maintained. The second version incorporated a series of automatic daily computer downloads from the inpatient pharmacy computer system. Web pages were built to dynamically display the formulary information from the database based on users' requests. The formulary enabled searching by brand or generic names, provided therapeutic category cross-references, listed the location of products within automated dispensing cabinets, provided accurate cost information, and was always up-to-date. Maintenance efforts drastically decreased. The current version has incorporated additional logic to meet users' needs. If no matches are found, the system expands its search by automatically linking to UMHS's inpatient pharmacy system repository of all drugs, finding matches to what the user entered, and then returning the names of therapeutically similar formulary agents to the user. A cross-index feature allows the system to return all the drugs that fall under the searched therapeutic category. Dramatic improvements have been made to UMHS's inpatient online formulary in the past two years. The current formulary provides a very low-cost, easily maintainable, and effective means to access the formulary and clinically relevant and timely information specific to each medication.

Prevalence and cost savings of therapeutic interchange among U.S. hospitals.

The prevalence and cost savings of therapeutic interchange (TI) among teaching, nonteaching, and investor-owned hospitals in the United States was studied. A survey was sent to all directors of pharmacy at hospitals listed in the 1999 American Hospital Association directory as having more than 100 beds; 463 (29.8%) hospitals responded. The survey elicited data about hospital demographics, the policies and personnel involved in TI, and the estimated cost savings incurred by the use of TI. Eighty-eight percent of teaching, 89% of nonteaching, and 100% of investor-owned hospitals reported having established TI policies and procedures; 88% of responding hospitals reported the use of TI as a means of formulary management. Individuals involved in the decision-making process for TI policies included physicians, pharmacists, and pharmacy and therapeutics committee members. Most responding hospitals reported having an automatic interchange procedure, and few required physician consent before the substitution was made. The most commonly substituted medication classes were histamine H2-receptor antagonists, proton-pump inhibitors, antacids, and quinolones. Differences in TI procedures and the medication classes commonly substituted were not significant between teaching and nonteaching hospitals. The annual dollar savings was estimated by 36% of teaching, 38% of nonteaching, and 50% of investor-owned hospitals and determined by record keeping in 18% of teaching, 20% of nonteaching, and 40% of investor-owned hospitals. Eighty-eight percent of teaching, 89% of nonteaching, and 100% of investor-owned hospitals have established TI policies. Significant variation in cost savings occurred when hospitals attempted to estimate the annual dollar savings, as no adequate commercially available software exists to perform this task.

Survey of hospital policies regarding low-molecular-weight heparins.

Hospital policies regarding the use of low-molecular-weight heparins (LMWHs) were studied. A questionnaire addressing the formulary status of LMWH products, the use of prescribing guidelines, programs for therapeutic interchange, and policies to promote alternatives to LMWHs when appropriate was prepared. The questionnaire was mailed in January 2001 to pharmacy directors at 70 hospitals located in 19 states. All the hospitals were members of a national group purchasing organization. Forty-nine usable responses were received, for a response rate of 70%. Enoxaparin and dalteparin were the LMWH products most likely to be on the respondents' formularies (98% and 29% of hospitals, respectively). About 29% of the hospitals reported having guidelines on the use of LMWHs. Among hospitals that did not, most indicated that they were considering or would like to implement such guidelines. The most commonly cited barrier to the development and implementation of guidelines was lack of pharmacy personnel. Ten percent of the respondents reported having therapeutic-interchange programs for LMWHs. Cited barriers to therapeutic interchange programs included lack of therapeutic equivalence among products and lack of comparable labeled indications. Policies to promote alternatives to LMWHs were reported by 18% of the respondents. A multihospital survey showed that many hospitals wanted but relatively few had prescribing guidelines for LMWHs.

Hospital policies regarding herbal medicines.

The prevalence and content of herbal policies and herbal formularies in the hospital setting were studied. Drug information centers affiliated with hospital pharmacies were surveyed by telephone. Hospitals with policies on herbal products were asked to provide detailed information about the policies. Of 70 hospitals included in the analysis, 53 (76%) had policies and procedures on the use of herbal products. Three hospitals (4%) reported having an herbal formulary. A majority of the existing policies required a physician order for an herbal product to be used inhouse. Many of the policies also required pharmacists to verify labeled product ingredients. Product administration, patient consent, and drug interaction screenings were addressed by some hospitals. Most hospitals reported having policies on the use of herbal products, but herbal formularies were rare.
