Group interventions for co-morbid insomnia and osteoarthritis pain in primary care: the lifestyles cluster randomized trial design.

Six weekly sessions of group cognitive-behavioral therapy for insomnia and osteoarthritis pain (CBT-PI), and for osteoarthritis pain alone (CBT-P) were compared to an education only control (EOC). Basic education about pain and sleep was comparable, so EOC controlled for information and group participation. Active interventions differed from EOC in training pain coping skills (CBT-P and CBT-PI) and sleep enhancement techniques (CBT-PI).

Population-based outreach for Chlamydia screening in men: results from a randomized trial.

Objective: To evaluate the feasibility and efficacy of population-based outreach strategies to improve genital Chlamydia trachomatis (CT) screening in men.

Study Design: In a randomized trial, male enrollees ages 21-25 (n = 8820) were selected from the automated files of Group Health Cooperative and randomized to: a letter + test-request card for a CT urine home sampling kit (arm 1, n = 2940); a letter + mail-back sampling kit (arm 2, n = 2940); or a usual care control (arm 3, n = 2940). One reminder was sent to arms 1 and 2.

Diabetes and the risk of acute urinary tract infection among postmenopausal women.

Objective: To examine whether the presence of diabetes alters the risk of acute urinary tract infection (UTI) in postmenopausal women.

Research Design And Methods: A case-control study of the Group Health Cooperative of Puget Sound (GHC), a staff-model nonprofit health maintenance organization in Washington State, was conducted. Subjects were women aged 55-75 years who had been members of GHC for at least 1 year and who had had an acute symptomatic UTI within the preceding month.
