What happens when a demonstration project ends. Consequences for a clinic and its clients.

The Los Angeles Enhanced Methadone Maintenance Project was a 5-year research demonstration project funded by the National Institute on Drug Abuse with the goal of reducing high-risk behavior for human immunodeficiency virus (HIV) among heroin users. A clinic was established for the purposes of the study and 500 clients with high-risk profiles were recruited into treatment. Follow-up assessments demonstrated that clients had reduced their drug use, criminal behavior, and HIV-risk behaviors after entering treatment. At the end of the project clients were given the option of continuing treatment at the clinic on a fee-for-service basis, transferring to another treatment provider, or undergoing detoxification. Clients who were eligible for Medicaid were likely to continue receiving methadone treatment, but those without Medicaid funding were not. The implications of terminating treatment among a high-risk population recruited into a research demonstration project are discussed.

The determination of commonly used iodinated contrast media in postmortem samples using HPLC and TLC.

A rapid micro method is described for the determination of diatrizoic, iothalamic, ioxaglic, and iopanoic acids in postmortem liver and blood. The compounds were extracted with methanol and analyzed by high performance liquid chromatography using a C18 column. The mobile phase consisted of methanol:PIC A with ultraviolet detection at 232 and 242 nm. Recoveries of about 85% were obtained. A thin layer chromatographic system is described which separates the four compounds. The spots were hydrolyzed and sprayed with a diazonium coupling reagent to produce colored spots with sensitivities of 0.02 to 0.1 micrograms. Postmortem levels are given for two deaths involving diatrizoic acid.

The driving force of physician partners.

The administrative team admits that involvement with physician partnerships requires a different set of management skills, but it's worth the effort to share common goals.
