Drug utilization review in an extended care facility. 1974.

Clinical pharmacy has expanded the scope of pharmaceutical services and one of the newer areas of involvement is the extended care facility. The author discusses the need, because of a limited budget, for better financial control of drug usage in Lions Gate Hospital's new 170 bed extended care unit. A need for pharmacy involvement in geriatrics because of the rising population of elderly people in extended care facilities and nursing homes and the complexities of using drugs in the elderly is discussed. The new extended care unit was provided with traditional pharmacy services and a pharmacist to participate in a patient review committee. This pharmacist monitored the patients' drug usage and made recommendations to the committee where applicable. The lowered costs of drug therapy in the extended care unit and the more efficacious use of certain medications are discussed in terms of pharmacy involvement. The author concludes that the pharmacist can make a significant contribution to the more economical use of drugs in extended care facilities and has a potential valuable role in improving patient care in this area.

Maternal worry about neonatal hearing screening.

OBJECTIVE: To identify and compare the prevalence and degree of maternal worry about neonatal hearing screening at the time of an initial neonatal hearing screen and rescreen in 1997 and 1999. STUDY DESIGN: We report on a prospective cross-sectional investigation of maternal worry about newborn hearing screening. Demographic data, maternal knowledge of hearing screening, and degree of maternal worry were collected on 307 mothers at the time of the neonatal screen and 40 mothers at the time of the rescreen. RESULTS: Degree of maternal worry was significantly greater at the rescreen compared to the screen. Mothers who reported greater worry at the time of the screen were more likely to be socioeconomically disadvantaged. Although maternal knowledge about hearing screening increased between the two time periods, degree of worry remained unchanged. CONCLUSION: Efforts to minimize the neonatal false-positive hearing screen rates and to educate mothers about hearing screening are indicated to minimize unnecessary worry.

The Rhode Island Hearing Assessment Program: experience with statewide hearing screening (1993-1996)

OBJECTIVE: The objective of this study was to evaluate key outcomes of a universal hearing screen/rescreen program for all births with transient evoked otoacoustic emissions in all 8 maternity hospitals in the state of Rhode Island over a 4-year period. STUDY DESIGN: This was a retrospective analysis of the hearing screen/rescreen refer data collected prospectively for 53,121 survivors born in Rhode Island between January 1, 1993, and December 31, 1996. Primary outcomes included the first-stage refer rates, rescreen compliance, diagnostic referral rates, identification rates, and the age of amplification. RESULTS: During this 4-year time period 11 infants were identified with permanent hearing loss, resulting in an impairment rate of 2 per 1000. The mean age of hearing loss confirmation decreased from 8.7 months to 3.5 months, and the age at amplification declined from 13.3 months to 5.7 months. CONCLUSION: We conclude that time and experience are important factors in the development and refinement of a universal hearing screen program. Hearing screen outcome data collected over a 4-year period in Rhode Island reveal a steady improvement in the percent of infants completing the 2-stage screen process, the stage 1 and stage 2 refer rates, compliance with rescreen and diagnostic testing, and significant improvement in the age of identification and age of amplification.

Proventil HFA provides protection from exercise-induced bronchoconstriction comparable to proventil and ventolin.

INTRODUCTION: During the 1970s, scientists suggested that the growing use of chlorofluorocarbons (CFCs) was contributing to depletion of the stratospheric ozone layer with potentially harmful results. A committee on the ozone layer organized the preparation of the Montreal Protocol. This protocol mandated the cessation of production and use of CFCs by January 1, 1996. The primary exemption to this ban is for the use of CFCs as propellants in metered dose inhalers (MDIs) for the treatment of asthma. Suitable replacement hydrofluoroalkane (HFA) propellants, such as HFA-134a, for use in MDIs have been identified. Albuterol, a selective beta-adrenergic agonist, currently widely available for inhalation asthma therapy, has been reformulated in HFA-134a (Proventil HFA). OBJECTIVE; To compare the efficacy of Proventil HFA to Ventolin, Proventil, and placebo (HFA-134a) MDI in protecting asthmatic patients from exercise-induced bronchoconstriction. METHODS: This was a randomized, single-blind, placebo-controlled, 4-period crossover study of asthmatic patients with documented exercise-induced broncho-constriction. Twenty patients self administered two puffs of either Proventil HFA, Ventolin, Proventil or placebo, from an MDI, 30 minutes prior to performing a standardized exercise challenge at the study site. Spirometry was performed predose and 5, 10, 15, 30, 45, 60, 75, and 90 minutes after completion of the exercise challenge. Heart rate and blood pressure were measured just prior to spirometry and a 12-lead ECG was performed 15 minutes after completion of the exercise challenge for measurement of the QT corrected interval. RESULTS: The primary efficacy variable was the smallest percent change from the predose FEV1 following exercise. The smallest percent change from predose FEV1 for Proventil HFA was 2.0 +/- 9.9 SD, similar to the 2.0 +/- 11.4 SD for Ventolin, and the 3.6 +/- 10.2 SD for Proventil. The smallest percent change from predose FEV1 for each of the active treatments was significantly different from placebo, -23.7 +/- 14.5. Twelve of the patients had a > or = 20% fall in FEV1 post-exercise with placebo pretreatment, but only 1, 1, and 0 had > or = 20% FEV1 falls after treatment with Proventil HFA, Ventolin, and Proventil respectively. Changes in heart rate, blood pressure and QT corrected interval were similar for the three active treatments following exercise. CONCLUSIONS: Proventil HFA provides protection against exercise-induced bronchoconstriction comparable to Ventolin and Proventil and protection superior to placebo. Proventil HFA has a safety profile similar to Ventolin when used to prevent exercise-induced bronchoconstriction.
