Behavioral Effects of Reducing the Daily Frequency of Phenothiazine Administration.

After an 11-day base line of behavioral observations, 24 chronic female schizophrenics were assigned to two groups matched for alertness. In the first treatment phase, the administration of phenothiazine medication of one group was switched from a multiple-dose schedule (three to four times per day) to a single daily administration, while the total dosage per day was held constant. The second group continued on a multiple administration schedule for 11 days and then was switched to a single daily dosage. A multivariate analysis of variance showed that there was no overall effect (positive or negative) due to the schedule change; however, preplanned t tests showed transitory decreases in nonfunctional behavior. The results are discussed in terms of implications for the administration of phenothiazines and the experimental analysis of drug effects.

A comparison of initial and established patient encounters using the Davis Observation Code.

BACKGROUND: Previous research has evaluated how communication during medical visits affects patient outcomes such as compliance, recall, and satisfaction. These prior studies generally did not control for new versus established patient visits. The objective of the present research was to explore differences between new and established patient encounters. METHODS: This research studied 62 new patient and 58 established patient encounters to a university-based family practice clinic. The Davis Observation Code was used to code and evaluate the encounters. RESULTS: Established patient encounters were shorter and involved more chatting, counseling, discussions of treatment effects, compliance checking, and requests for specific patient behavior changes regarding health promotion. On the other hand, established patient encounters involved less structuring of the interaction with the patient, less history taking, and fewer discussions regarding family information, smoking, and substance abuse. CONCLUSIONS: The results indicate that what takes place during the medical interview is highly dependent on physician-patient familiarity. Future research on physician-patient interactions should consider whether the interactions represent new or established visits.
