Treatment participation and outcome among problem drinkers in a managed care alcohol outpatient treatment program.

This article uses Markov analysis to investigate patterns of treatment participation of 361 patients treated in the alcohol and drug abuse programs of a large group model Health Maintenance Organization (HMO) to examine how participation is related to abstinence. Findings indicate that 82% of the patients in treatment one month after intake were in treatment three months later, and treatment retention dropped to 46% by month 6. Findings also indicate that 74% of patients abstinent and in treatment at month 1 remained so at month 3. Abstinence at the first three-month interval was a strong predictor of abstinence at later time periods. A multivariate analysis showed that an expressed desire to stop alcohol use upon entry into treatment was the most consistent predictor of both treatment participation and abstinence at most time points. Treatment participation was also a significant predictor of abstinence.

Long-term reduction of intraocular pressure after repeat argon laser trabeculoplasty.

Thirty-eight eyes (in 31 patients with glaucoma) that had shown a favorable response to an initial argon laser trabeculoplasty had a repeat laser trabeculoplasty four to 81 months (mean +/- S.E.M., 23 +/- 3 months) later because of inadequately controlled intraocular pressures. A mean (+/- S.E.M.) of 65 +/- 3 burns (range, 50 to 115) were given during the initial laser trabeculoplasty, and 58 +/- 2 burns (range, 36 to 100) were given during the first repeat treatment. Three months after the first repeat laser trabeculoplasty, one eye (3%) had undergone filtering surgery and 30 eyes (78%) were considered successes. Of the 30 eyes that were followed up for 12 months after the first repeat laser trabeculoplasty, two (7%) had undergone filtering surgery, three (10%) had received a second repeat laser trabeculoplasty, and 22 (73%) were successes. Fifteen eyes underwent a second repeat laser trabeculoplasty at six to 47 months (mean +/- S.E.M., 21 +/- 3 months) after the first repeat laser trabeculoplasty. Seven (47%) of these eyes required filtering surgery within three to 12 months after the second repeat laser trabeculoplasty. Four of 38 (11%) of the initial, two of 38 (5%) of the first repeat, and zero of 15 of the second repeat laser trabeculoplasty treatments resulted in a one- to two-hour rise in intraocular pressure of at least 10 mm Hg.
