It is controversial whether prolonged antibiotic treatment effective for patients in whom symptoms persist after the recommended acute Lyme disease.We conducted two randomized trials: one 78 who were seropositive IgG antibodies to Borrelia burgdorferi at time of enrollment and other 51 seronegative. The received either intravenous ceftriaxone, 2 g daily 30 days, followed by oral doxycycline, 200 mg 60 or matching placebos. Each patient had well-documented, previously treated disease but...
Objectives. The authors examine the data quality and measurement performance of Primary Care Assessment Survey (PCAS), a patient-completed questionnaire that operationalizes formal definitions primary care, including definition recently proposed by Institute Medicine Committee on Future Care. Methods. PCAS measures seven domains care through 11 summary scales: accessibility (organizational, financial), continuity (longitudinal, visit-based), comprehensiveness (contextual knowledge patient,...
Many health status surveys have been designed for mail, telephone, or in-person administration. However, with rare exception, investigators not studied the effect survey mode of administration has on way respondents assess their and other important parameters (such as response rates, nonresponse bias, data quality), which can affect generalizability results. Using a national sampling frame noninstitutionalized adults from General Social Survey, we randomly assigned to mail (80%)...
Objective To define clinically meaningful changes in 2 widely used health-related quality of life (HQL) instruments studies patients with rheumatoid arthritis (RA).

Objective: The purpose of this study was to assess psychometric properties the six-item Headache Impact Text (HIT-6™) across episodic and chronic migraine. Methods: Using a migraine screener number headache days per month (HDPM), participants from National Survey (NSHI) HIT-6 validation (HIT6-V) were selected for study. Eligible categorized into three groups: (CM: ≥ 15 HDPM); (EM: < non-migraine headaches. Reliability validity evaluated. Results: A total 2,049 survey met...

Additional patients with CM needed. Methods.— Cross‐sectional data were collected via web‐based survey 9 countries/regions. Participants...
The Headache Impact Test (HIT)-6 was developed and has been validated in patients with various types of headache. objective this study to report the psychometric properties HIT-6 among chronic migraine.Data came from two international, multicenter, randomized, double-blind, placebo-controlled clinical trials migraine (N = 1,384) undergoing prophylaxis therapy. Confirmatory factor analysis differential item functioning (DIF) were used test latent structure cross-cultural comparability HIT-6....
