In the outpatient treatment of depression, the potential of diagnostic and therapeutic methods is seldom exhausted resulting in variable quality of treatment and partly insufficient cost effectiveness. Implementation of a guideline-oriented reimbursement system seems to be an option to improve quality of treatment. Corresponding incentive systems have been outlined and evaluated for the health care of somatic diseases such as diabetes. Acting on these experiences, an attempt was made to utilize them for the area of psychiatric disorders. Taking depression as an example, a model for a quality-oriented, guideline-based reimbursement system for general and specialist practice is presented.
BACKGROUND: Lack of adherence to blood pressure-lowering medication is a major reason for poor control of hypertension worldwide. The objective of this study was to determine the effectiveness of interventions to increase adherence to blood pressure-lowering medication. METHODS: We performed a systematic review of randomized controlled trials and searched for all-language publications in the Cochrane Controlled Trials Register, MEDLINE, EMBASE, and CINAHL in April 2002. RESULTS: We included 38 studies testing 58 different interventions and containing data on 15 519 patients. The studies were conducted in 9 countries between 1975 and 2000. The duration of follow-up ranged from 2 to 60 months. Because of heterogeneity between studies in terms of interventions and the methods used to measure adherence, we did not pool the results. Simplifying dosing regimens increased adherence in 7 of 9 studies, with a relative increase in adherence of 8% to 19.6%. Motivational strategies were partly successful in 10 of 24 studies with generally small increases in adherence up to a maximum of 23%. Complex interventions comparing more than 1 technique increased adherence in 8 of 18 studies, ranging from 5% to a maximum of 41%. Patient education alone seemed largely unsuccessful. CONCLUSIONS: Reducing the number of daily doses appears to be effective in increasing adherence to blood pressure-lowering medication and should be tried as a first-line strategy, although there is so far less evidence of an effect on blood pressure reduction. Some motivational strategies and complex interventions appear promising, but we need more evidence on their effect through carefully designed randomized controlled trials.
BACKGROUND: Attention-deficit hyperactivity disorder is an early-onset, clinically heterogenous disorder of inattention, hyperactivity, and impulsiveness. The diagnosis and treatment of attention-deficit hyperactivity disorder continues to raise controversy, and, there is also an increase in treatment options. In this 6-week double blind, placebo controlled-trial, we assessed the effects of zinc plus methylphenidate in the treatment of children with attention deficit hyperactivity disorder. To the best of our knowledge, this study is the first double blind and placebo controlled clinical trial assessing the adjunctive role of zinc in ADHD. METHODS: Our subjects were 44 outpatient children (26 boys and 18 girls) between the ages of 5-11 (mean +/- SD was 7.88 +/- 1.67) who clearly met the DSM IV diagnostic criteria for attention-deficit hyperactivity disorder and they were randomized to methylphenidate 1 mg/kg/day + zinc sulfate 55 mg/day (with approximately 15 mg zinc element) (group 1) and methylphenidate 1 mg/kg/day + placebo (sucrose 55 mg) (group 2) for a 6 week double blind clinical trial. The principal measure of the outcome was the Teacher and Parent ADHD Rating Scale. Patients were assessed by a child psychiatrist at baseline, 14, 28 and 42 days after the medication started. RESULTS: The present study shows the Parent and Teacher Rating Scale scores improved with zinc sulfate over this 6-week, double blind and placebo controlled trial. The behavior of the two treatments was not homogeneous across the time. The difference between the two protocols was significant as indicated by the effect on the group, the between-subjects factor (F = 4.15, d.f. = 1, P = 0.04; F = 4.50, d.f. = 1, P = 0.04 respectively). The difference between the two groups in the frequency of side effects was not significant. CONCLUSIONS: This double-blind, placebo-controlled study demonstrated that zinc as a supplementary medication might be beneficial in the treatment of children with attention-deficit hyperactivity disorder. However, further investigations and different doses of zinc are required to replicate these findings in children with ADHD.
