No consistent relationships were observed between increased copayments per dispensing and medical care utilization and expense. Future research needs to address the impact on the classes of medications received and related health status, and the impact of larger increases in copayments per dispensing on medical care and health-related factors.

The purpose of this study is to investigate the utility of a self-report screening instrument, the Health Status Form (HSF), to predict elderly members at risk of frailty in the subsequent year. The predictive ability of self-report HSF data was also compared to the predictive ability of inpatient discharges and pharmacy dispensings from administrative utilization databases. Four HSF variables best predicted elderly members at risk of frailty: (a) age, (b) indicating that health conditions interfered with daily activities, (c) needing or receiving assistance from another person for bathing, and (d) needing or receiving assistance from another person for taking medications. The predictive model yielded sensitivity 50.7%, specificity 97.8%, and correctly classified 90.9% of the population. Self-report population-based screening is a reliable method for predicting elderly members at risk of frailty in the coming year. Further studies should test a new brief instrument composed of portions of validated measures as a stand alone screener to select frail members for care management purposes.

The experience with pulmonary disease caused by Mycobacterium avium complex (MAC-PD) was examined over a 12-yr period in a nonreferral setting. The 29 patients with the disease constituted 30% of all pleuropulmonary mycobacterioses. The mean annual incidence rate was 1/100,000. Sixty-two percent of patients were female, the majority of whom had no discernible preexisting pulmonary disorder to account for their susceptibility. A short- and long-term favorable response to therapy was observed in more than 90% of the 16 patients treated with intent to cure. Suggested as plausible explanations for the favorable response rate compared with previous studies originating in referral settings were: absence of adverse selection as shown by a smaller proportion of patients with far-advanced cavitary disease or with previous treatment failure, and a larger proportion of female patients. A previously unreported pattern of MAC-PD was observed: disease limited to the lingula or middle lobe occurred in 21% of the patients, all female. A rarely identified pattern, primary disease in a 3-yr-old exposed to pet birds, is reported.
