An unusual cause of intestinal obstruction--computed tomographic findings.

Computed tomographic findings in a case of acute intestinal obstruction due to ingested heroin packages are described. Ingestion of drug packages for the purpose of contraband transportation is a well-known method employed by drug-traffickers and intestinal obstruction may be seen as a complication. Plain radiographs and history are usually adequate for diagnosis when required for medico-legal purposes.

Adherence to oral tamoxifen: a comparison of patient self-report, pill counts, and microelectronic monitoring.

PURPOSE: Recent innovations allow the integration of microelectronics into drug packaging, providing a continuous record of the interactions of the patient with the drug package. We hypothesized that adherence to oral tamoxifen, as measured by a pressure-activated microelectronic monitoring device, would be significantly discrepant from traditional measures of patient adherence, ie, patient self-report (SR) and pill counts (PCs). PATIENTS AND METHODS: Twenty-six patients receiving oral tamoxifen therapy were assessed by patient SR, PCs, and Medication Event Monitoring System (MEMS; Aprex Corp, Fremont, CA) microelectronic monitoring. A microprocessor in the MEMS cap recorded each opening as a presumptive dose, listing the date, time, and duration of opening for later retrieval on a microcomputer. Patients were not informed that their adherence was to be monitored electronically or that PCs would be performed. RESULTS: A total of 2,102 days (70.1 months) of tamoxifen therapy were monitored; patients were monitored for a mean of 2.92 months of tamoxifen therapy. SR adherence to oral tamoxifen was significantly higher than that suggested by either PCs (SR missed doses only v PC, P = .008) or MEMS adherence monitoring (SR missed doses only v MEMS missed doses only, P = .005; SR dosing-interval errors only v MEMS dosing-interval errors only, P < .0001; SR all dosing errors v MEMS all dosing errors, P < .0005). PC data also suggested significantly higher adherence rates than MEMS monitoring. CONCLUSION: Microelectronic adherence monitoring provides both confirmatory and complimentary data regarding adherence behavior, while also allowing for the evaluation of patterns of nonadherence. Patient SRs and PCs likely overestimate the degree to which patients adhere to their tamoxifen regimen.

Medication compliance in elderly outpatients using twice-daily dosing and unit-of-use packaging.

OBJECTIVE: To determine the effect of unit-of-use drug packaging of medications on compliance among elderly outpatients treated with complex medication regimens. DESIGN: Nonblind, randomized, clinical trial. SETTING: Geriatric outreach health centers in urban public housing units for independent-living elderly people. PATIENTS: Thirty-one patients (aged > or = 60 y), each taking three or more prescribed medications. Patients were randomly assigned to one of three study groups: group 1 (n = 12), no change in dosing or packaging; group 2 (n = 10), conventional packaging with twice-daily dosing; group 3 (n = 9), unit-of-use packaging with twice-daily dosing. INTERVENTION: A unit-of-use package consisting of a two-ounce plastic cup with a snap-on lid containing all medications to be taken at the time of dosing. MAIN OUTCOME MEASURES: Medication compliance was assessed monthly for six months using tablet counts. RESULTS: Medication compliance was significantly better in group 3 (92.6 percent) using unit-of-use packaging compared with either group 1 (79 percent) or group 2 (82.6 percent) (p = 0.017). Compliance did not differ between groups 1 and 2. CONCLUSIONS: In this small study of elderly outpatients taking three or more medications, unit-of-use packaging and twice-daily dosing improved medication compliance compared with conventional packaging.

[The gastrointestinal concealment of illegal drugs].

The clinical, radiological and analytical aspects, and the complications observed in 16 cases of swallowing or insertion into the rectum of illicit drugs ("body-packing") are described. The drugs detected were heroin (6 cases), cocaine (5 cases) and cannabis (5 cases). In 15 cases abdominal plain X-rays were useful in the detection of the drug packages, their position and progression in the gastrointestinal tract and the presence of complications. The most valuable finding for radiologic diagnosis was the presence of a radiolucent halo surrounding the drug packages, or "double condom" sign, which was observed in 13/15 cases (87%). Urine analysis was positive for opiates or metabolites of cocaine in 7/9 cases (78%). One case presented acute heroin intoxication and three subjects gastric or intestinal obstruction requiring surgical treatment. In another case a packet, which had been retained in the stomach for five days, was extracted by upper gastrointestinal endoscopy using a Dormia basket with no complications.

A drug-to-drug interaction package.

This paper describes an electronic database for handling the interactions between active principles administered to various patients. The computer used is a personal computer with adequate mass memory, software, and data obtained from pharmacological sources. The main features of this work are: 'all-patient' orientation, a special sentence-coding system, suitability for most existing catalogues of drug interactions, drug-keyed and cause-and-effect-keyed accesses, menu-driven interaction between the user (a physician) and the system, implementation on a personal computer (as available in most hospital departments) and activation from other programs.

The feasibility of barcode-based dispensing quality assurance programs.

A study was conducted to evaluate the feasibility of using barcodes in an outpatient pharmacy quality assurance program. In the first step of this study, adhesive labels containing a barcode representation of the National Drug Code (NDC) identification for the hospital's formulary medications were printed for each stock bottle or drug package used in dispensing. When an outpatient prescription was presented to the pharmacist, a label containing a barcode representation of the NDC identification for the prescribed medication was generated on-line and attached to the back of the prescription form. After the prescription item was filled by the pharmacist, an automated check was performed with a scanning wand by comparing the barcode on the prescription with the previously generated barcode on the stock bottle or drug packaging. A match indicated that the correct medication had been dispensed. Elaborations on this basic automated system for a barcode-based dispensing quality assurance program are suggested.

Increasing patient compliance with prescriptions.

In this review, we address the problem of patient noncompliance with taking prescribed medication. Eight methods of improving patient compliance are outlined as follows: (1) improving the physician-patient interaction, (2) fear-arousing health messages, (3) education, (4) written instructions, (5) special drug packaging, (6) tailoring, (7) self-monitoring, and (8) contingency management. Several problems associated with the use of compliance-enhancing strategies are mentioned. Finally, the Health Belief Model is suggested as a framework capable of integrating some of the research findings in this area.

An anaesthetic drug error: minimizing the risk.

A medication error caused a near fatal cardiac arrest in a previously healthy patient undergoing elective surgery. Inadvertent epinephrine injection induced ventricular dysrhythmias, hypertension, hypotension and pulmonary oedema. The case was investigated using critical-incident technique and was reviewed by the Risk Management Team of the Department of Anaesthesia. The purpose of this report is to present the recommendations resulting from the investigation. These include: improved resident training in intravenous drug management, the use of anaesthetic drug ampoules with distinct labels, and the development of a standardized colour code system for labels on anaesthetic drug ampoules. Furthermore, it is recommended that all anaesthetic drug errors be reported to the Canadian agencies responsible for drug packaging in order to identify patterns in anaesthetic drug errors, and to facilitate the implementation of effective drug identification systems.
