Can a nationwide media campaign affect antibiotic use?

OBJECTIVE: To evaluate the effectiveness of a nationwide media campaign to reduce antibiotic overuse among children. STUDY DESIGN: Prospective observational study of the pediatric population of a health maintenance organization (HMO) comparing antibiotic use during the baseline (November 2004-February 2005) and study (November 2005-February 2006) periods. METHODS: During January 2006 the HMO conducted a media campaign to increase public awareness of the risks of misusing antibiotics, particularly for influenza-like diseases. Antibiotic purchasing rates during specific periods in the study winter were compared with those during corresponding periods in the baseline winter among children diagnosed with upper respiratory infection (URI), otitis media (OM), or pharyngitis. After the intervention, a random subset of the study population was surveyed by telephone to estimate the level of exposure to the campaign and attitudes toward antibiotic use. RESULTS: The study population consisted of 101,401 children in the baseline winter and 84,979 in the study winter. We noted reductions in antibiotic purchasing for URI, OM, and pharyngitis during the postintervention period compared with the preintervention period (URI odds ratio [OR] = 0.75, 95% confidence interval [CI] = 0.69, 0.81; OM OR = 0.65, 95% CI = 0.59, 0.72; pharyngitis OR = 0.93, 95% CI = 0.89, 0.97). Parents of children with URI exposed to the media campaign were more likely to agree with standards of appropriate antibiotic use than parents not exposed (F(1) = 4.18, P = .04). CONCLUSIONS: A media campaign aimed at changing patient behavior can contribute to reducing the rate of inappropriate antibiotic use.

Physician speciality and adherence to guidelines for the treatment of unsubstantiated uncomplicated urinary tract infection among women.

PURPOSE: To evaluate the variance in rates of physician adherence to guidelines for the empiric treatment of uncomplicated urinary tract infection (UTI) in women recommending either trimethoprim-sulfamethoxazole (TMP-SMX) or nitrofurantoin, in all relevant physician subspecialities practising in a managed care community setting in Israel. METHODS: Data were derived from the computerised medical records of Maccabi Healthcare Services, a health maintenance organisation (HMO) in Israel providing care to more than 1.6 million members nation-wide. The study population included women aged 18-75 years without risk factors for complicated UTI who were treated empirically with antibiotics for a diagnosis of acute cystitis or UTI. The data set consisted of 64,236 initial physician-patient encounters from July 2000 to June 2002. Physician adherence to guidelines was calculated by comparing the proportion of cases treated with each individual drug. A binary regression model was used to evaluate factors associated with suboptimal adherence to the guidelines. RESULTS: Nitrofurantoin was the most frequently prescribed drug (18.51%), followed by TMP-SMX (17.04%) for a crude rate of adherence of 35.6%. Adherence was observed to be highest in cases treated by urologists (OR=2.8, 95%CI: 2.4, 3.3), followed by gynaecologists (OR=1.9, 95%CI: 1.7, 2.31), with family practice as the referent speciality. The medical school attended was also found to be significant. CONCLUSIONS: Physician speciality was found to be significantly associated with rate of adherence to guidelines, with higher rates being observed amongst specialities such as urologists who presumably have greater familiarity with the subject matter.

Health Value Added (HVA): linking strategy, performance, and measurement in healthcare organizations.

This paper describes "Health Value Added"--an innovative model that links performance measurement to strategy in health maintenance organizations. The HVA model was developed by Maccabi Healthcare Services, Israel's second largest HMO, with the aim of focusing all its activities on providing high quality care within budgetary and regulatory constraints. HVA draws upon theory and practice from strategic management and performance measurement in order to assess an HMO's ability to improve the health of its members. The model consists of four interrelated levels--mission, goals, systems, and resources--and builds on the existence of advanced computerized information systems that make comprehensive measurements available to decision makers in real time. HVA enables management to evaluate overall organizational performance as well as the performance of semi-autonomous units. In simple terms, the sophisticated use of performance measures can help healthcare organizations obtain more health for the same money.
