Design and results of a group counter-detailing DUR educational program.

PURPOSE: The study objectives were to (1) design, (2) implement and (3) evaluate a multi-step educational program as an integral component of a healthcare system's activities to improve medication use quality and control drug costs. Design and implementation of the educational program were based upon established principles of changing prescriber behavior. Two classes of oral medications, antihistamines and antibiotics, were targeted. METHODS: A before-after nonequivalent comparison group design with 2 comparison groups was used for evaluation. Medication claims data from the same time period one year previously were used as historical controls. Prescribing rates, net savings and prescribers' attitudes were assessed. RESULTS: Prescribing trends in the treatment group but not comparison groups generally reflected changes consistent with the educational message. A net savings of $84 was achieved in the antihistamine program. A net loss of ($2722) was seen in the antibiotic program. Over 75 percent of prescribers agreed or strongly agreed that the educational program was an appropriate mechanism to optimize medication use. Level of exposure and practice years affected perceived knowledge gains. CONCLUSION: The group counter-detailing DUR educational program was effective in improving prescribing rates. Prescribing rate changes and economic impacts differed by therapeutic category. The entire program was well accepted among prescribers including physicians and nurse practitioners.

Antihistamines: the old and the new.

Several pharmacologic agents provide antihistamine effects by acting at the H1 histamine receptor site. The classic agents are relatively nonselective, resulting in a wide range of effects, both therapeutic and undesirable. The newer agents preferentially block peripheral H1 receptor sites and, consequently, have fewer side effects, including sedation. Antihistamines are useful in the treatment of allergic conditions, Parkinson's disease, insomnia and some forms of nausea, and provide symptomatic relief of cough and other conditions associated with respiratory tract infections. Certain agents may play a role in the treatment of asthma and anorexia. Selection of a specific agent should be based on cost and the minimization of side effects. The classic antihistamines provide an inexpensive and highly effective means of treating histamine-mediated symptoms. The bothersome central nervous system side effects can be alleviated by taking the drugs at bedtime; their prolonged tissue half-life allows dosing once or twice a day for 24-hour clinical relief. The newer, more expensive nonsedating antihistamines are acceptable alternatives for patients who are incapable of tolerating the effects of classic agents.

Advances in the prevention, diagnosis and treatment of deep venous thrombosis.

Deep venous thrombosis of the leg is associated with hospitalization in up to 600,000 Americans each year. Prevention is possible; the preventive strategy varies according to the degree of risk. Noninvasive techniques, especially impedance plethysmography, have revolutionized the diagnosis of deep venous thrombosis and should be the diagnostic methods of first choice. Patients with suspected calf vein thrombi but negative impedance plethysmography studies need not receive anticoagulation therapy as long as serial studies remain negative. Five days of intravenous heparin constitutes adequate treatment, and warfarin can be initiated on the first day of heparin therapy. Intravenous heparin will most likely be replaced by the subcutaneous, low-molecular-weight form once it becomes widely available. Bleeding is the principal side effect of anticoagulation therapy; careful attention to pharmacokinetics and pharmacodynamics can minimize this side effect. Use of the prothrombin time international normalized ratio allows safer, more reproducible anticoagulation with oral agents.

A systematic approach to educating elderly patients about their medications.

The purpose of this study was to evaluate a pharmacist-initiated, total package, patient education program based on the concepts described in the PRECEDE model. This program was directed towards 94 therapeutically complex elderly patients and consisted of a medication history, therapeutic evaluation, patient education needs assessment, patient education session, and a patient feedback/satisfaction telephone interview. Pharmacists identified on average 5.6 medication-related problems and provided an average of 6.2 recommendations. Problems commonly identified involved inadequate drug knowledge (25.5%), noncompliance (22.7%), and inappropriate drug use (17.4%). Typical recommendations included altering drug use (35.9%), improving compliance behavior (18.1%), and improving communication with health professionals (18.1%). Patient satisfaction with the education session was overwhelmingly positive. Based on the findings of this study, it is apparent that a patient education program based on the PRECEDE model can be used successfully by pharmacists to prepare education plans that would benefit the therapeutically complex elderly patient.
