There are two series of files: MS-3092 consists of 510 case files for patients treated with hallucinogenic drugs at Hollywood Hospital, with opening file dates from 1957 to 1968. As some patients returned for later treatments some of the material may date from the early 1970's. These files were kept in a separate series from Hollywood's other patient case files. Most of the files contain correspondence and an autobiography recording answers to questions about early childhood, family relations, sexual history, mental health issues and problems with addictions. A standard file would also include a Minnesota Personality Profile, an analysis by a psychiatrist, a medical report on overall health, and a detailed log of the drugs that were administered and the patient's behavior while undergoing the hallucinogenic experience. Patients were also encouraged to prepare a report on their experience after the session, and to evaluate its benefit. The case files are arranged in ascending order by patient case file number. Box 1 of MS-3092 contains index cards, filed alphabetically by patient name. Based on this index, more than 800 patients were treated with hallucinogenic drugs at the Hollywood Hospital, but only two thirds of the files have been located and transferred. MS-3093 contains alphabetically-arranged index cards (Boxes 121 and 122) and selected patient case files for Hollywood Hospital patients who were NOT treated with hallucinogens (10 boxes). The majority of the patients were treated for alcoholism. MS-3093 patient files were created between 1944 and 1975. The files consist mainly of Patient Identification Sheets, Physician's Orders and Progress Notes, Clothing and Article Lists, Laboratory Reports, History and Physical Examinations, Admission-Separation Records, and Consent for Treatment forms. Approximately 8% of the original 15,000 files were selectively retained, based on their year of file closure.
