Quality assessment methods for drug class reviews for the Drug Effectiveness Review Project Study quality is objectively assessed using predetermined criteria for internal validity, based on the combination of the US Preventive Services Task Force and the National Health Service Centre for Reviews and Dissemination criteria. This appendix lists questions that are posed for each included study in order to assess study quality. These quality-assessment questions differ for systematic reviews, controlled trials, and nonrandomized trials. Regardless of design, all studies that are included are assessed for quality and assigned a rating of “good,” “fair,” or “poor. A fatal flaw is failure to meet combinations of criteria that may indicate the presence of bias. An example would be inadequate procedure for randomization or allocation concealment combined with important differences in prognostic factors at baseline. Studies that meet all criteria are rated good quality, and the remainder is rated fair quality. As the fair-quality category is broad, studies with this rating vary in their strengths and weaknesses: The results of some fair-quality studies are likely to be valid, while others are only probably valid. A poor-quality trial is not valid; the results are at least as likely to reflect flaws in the study design as a true difference between the compared drugs. Does the review report a clear review question and inclusion/exclusion criteria that relate to the primary studies? A good-quality review should focus on a well-defined question or set of questions. These questions ideally are reflected in the inclusion/exclusion criteria, which guide the decision of whether to include or exclude specific primary studies. The criteria should relate to the 4 components of study design: indications (patient populations), interventions (drugs), and outcomes of interest. In addition, details should be reported relating to the process of decision-making, such as how many reviewers were involved, whether the studies were examined independently, and how disagreements between reviewers were resolved. Is there evidence of a substantial effort to search for all relevant research? If details of electronic database searches and other identification strategies are given, the answer to this question usually is yes. Ideally, search terms, dates, and language restrictions should be presented. In addition, descriptions of hand searching, attempts to identify unpublished material, and any contact with authors, industry, and research institutes should be provided. The appropriateness of the database(s) searched by the authors should also be considered. For example, if only Medline was searched for a review looking at proton pump inhibitors then it is unlikely that all relevant studies were located. Is the validity of included studies adequately assessed? A systematic assessment of the quality of primary studies should include an explanation of the criteria used (for example, how randomization was done, whether outcome Proton pump inhibitors Page 116 of 121 Final Report Update 5 Drug Effectiveness Review Project assessment was blinded, whether analysis was on an intention-to-treat basis). Authors may use a published checklist or scale or one that they have designed specifically for their review. Again, the process relating to the assessment should be explained (how many reviewers were involved, whether the assessment was independent, and how discrepancies between reviewers were resolved). Is sufficient detail of the individual studies presented? The review should demonstrate that the studies included are suitable to answer the question posed and that a judgment on the appropriateness of the authors’ conclusions can be made. If a paper includes a table giving information on the design and results of the individual studies or includes a narrative description of the studies within the text, this criterion is usually fulfilled. If relevant, the tables or text should include information on study design, sample sizes, patient characteristics, interventions, settings, outcome measures, follow-up periods, drop-out rates (withdrawals), effectiveness results, and adverse events. The authors should attempt to synthesize the results from individual studies. In all cases, there should be a narrative summary of results, which may or may not be accompanied by a quantitative summary (meta-analysis). For reviews that provide a meta-analysis, heterogeneity between studies should be assessed using statistical techniques. If heterogeneity is present, the possible reasons (including chance) should be investigated. In addition, the individual studies should be weighted in some way (for example, according to sample size or inverse of the variance) so that studies that are considered to provide the most reliable data have greater impact on the summary statistic. Controlled Trials Assessment of internal validity 1. Was the assignment to treatment groups really random? Adequate approaches to sequence generation: Computer-generated random numbers Random-numbers table Inferior approaches to sequence generation: Use of alternation, case record number, birth date, or day of week Not reported 2. Adequate approaches to concealment of randomization: Centralized or pharmacy-controlled randomization Serially numbered identical containers On-site computer-based system with a randomization sequence that is not readable until allocation Inferior approaches to concealment of randomization: Use of alternation, case record number, birth date, or day of week Proton pump inhibitors Page 117 of 121 Final Report Update 5 Drug Effectiveness Review Project Open random-numbers list Serially numbered envelopes (Even sealed opaque envelopes can be subject to manipulation. Were the groups similar at baseline in terms of prognostic factors? Were outcome assessors blinded to the treatment allocation? Was the patient kept unaware of the treatment received? Did the article include an intention-to-treat analysis or provide the data needed to calculate it (number assigned to each group, number of subjects who finished in each group, and their results)? Did the article report attrition, crossovers, adherence, and contamination?

The number of total adverse events and withdrawals due to adverse events were similar for the drugs discount viagra extra dosage 130mg visa. However buy 200 mg viagra extra dosage otc, more patients reported somnolence with trazodone (16% compared with 23%) cheap 200mg viagra extra dosage fast delivery. A trial of comparing trazodone with zaleplon in psychiatric inpatients was rated poor quality and does not provide additional comparative information about newer insomnia drugs 52 compared with trazodone discount viagra extra dosage 200mg otc. Insomnia Page 35 of 86 Final Report Update 2 Drug Effectiveness Review Project Long-term safety There is limited evidence about the long-term safety of newer drugs for insomnia and no direct evidence about their comparative long-term safety. Eszopiclone 90 In a 6-month placebo-controlled trial of eszopiclone 3 mg, the rate of serious adverse events was 2. The most common serious adverse events were gastrointestinal disorder (0. After discontinuation of the drug, similar overall rates of “new” events (defined as either not seen during the treatment period or worsening after the treatment period) were seen in placebo (10. There were no reports of seizures, hallucinations, or perceptual-disturbance events. The most common adverse event was unpleasant taste (26. Over 6 months, the rate of discontinuation due to adverse events was 12. The most common reasons for discontinuation were somnolence (2. All patients who completed the double-blind phase were eligible to participate in the open-label extension. Of the 788 patients enrolled in the 6-month double-blind phase, 471 patients continued into the 6-month open-label extension study (59. Improvements in sleep outcomes were sustained; rebound 108 insomnia and withdrawal effects were not reported. The most common treatment-related adverse events were unpleasant taste (6. A more recently published 6-month study of nightly treatment with eszopiclone 3 mg was 119 conducted in 828 patients with chronic insomnia. Rates of withdrawals due to adverse events were similar in the eszopiclone (9%) and placebo (8%) groups. By the end of the study, 37% of eszopiclone and 52% of placebo patients withdrew. There were more reports of somnolence, unpleasant taste, and myalgia in the eszopiclone group than the placebo group. There was no evidence of withdrawal symptoms or rebound insomnia. Zaleplon 12 A one-year open-label extension of a head-to-head trial was conducted to assess the longer- 128 term safety of zaleplon 5 mg in older patients. In order to qualify for the extension phase, patients must have completed the trial and a 7-day placebo run-out without adverse effects. Thus this extension was limited to a sample of patients highly selected to be less likely to experience discontinuation effects. Sixty-four percent of patients who completed the 2-week trial enrolled in the extension study. Results of this open-label extension are reported in combination with those of an extension of a different, unpublished trial, also conducted in older people. The most frequent adverse events were headache (27%) and infection (13%). The most frequent adverse events resulting in discontinuation were pain (5%), somnolence or dizziness (4%), and gastrointestinal disturbance (2%). There was a significant increase in sleep latency, number of Insomnia Page 36 of 86 Final Report Update 2 Drug Effectiveness Review Project awakenings, and reduced total time slept on the first night after discontinuation, but these did not approach original baseline levels. Zolpidem Two open-label studies in general practice patients in France assessed the safety of 6 months of 137, 142 137 treatment with zolpidem. One looked at zolpidem 10 mg or 20 mg in 96 patients over age 40. All 96 patients were followed for 6 months; 49 of these patients continued treatment for an additional 6 months. Four of the 49 patients who continued treatment after 6 months withdrew (8%); two experienced nightmares, but these were not considered to be related to the study drug. In the second study, 107 patients were enrolled, and 20 patients withdrew before 6 months (18. Adverse events included malaise (5 events), vertigo (5 events), and anterograde amnesia (5 events). Patients experiencing vertigo and confusion were all over age 70. There was no evidence of tolerance over the 6-month course of the study, and no rebound insomnia. Zolpidem extended-release In a 6-month placebo-controlled trial of zolpidem extended-release 12. The most common adverse events associated with zolpidem extended-release were headache (10. There was no evidence of tolerance to treatment over the 6-month study period and no rebound insomnia on the first 3 nights after discontinuation of medication. Zopiclone We identified no prospective studies that assessed the long-term safety of zopiclone. Abuse and dependence 149-166 Abuse and dependence have been associated with zolpidem and zopiclone. A review of case reports and epidemiological data found most patients abusing or becoming dependent on 167 zolpidem had a history of drug or alcohol abuse or other psychiatric conditions. A study of French data on zolpidem collected by the Centers for Evaluation and Information on Pharmacodependence found that from 1993 to 2002, the period of the study, health professionals spontaneously reported an increasingly higher number of cases of abuse or dependence 144 associated with zolpidem. In 1993 <1% of abuse and dependence reports included zolpidem, and by 2002 almost 5. An epidemiological survey of falsified or forged prescriptions shows that the popularity of zolpidem among forged prescriptions has increased: It th was the 6 most common drug for which prescriptions were falsified in 1998 and had risen to #1 Insomnia Page 37 of 86 Final Report Update 2 Drug Effectiveness Review Project by 2004. The ratio of the number of forged zolpidem prescriptions to the number of legitimate zolpidem prescriptions indicates that zolpidem’s falsification ratio is moderate, although higher than that of the leading benzodiazepine in France (specific data not reported). Finally, annual surveys of drug abusers show that the number of patients using zolpidem increased from <1% in 1998 to 4% in 2001. Nearly all patients abusing zolpidem were abusing more than one drug, 1 of 2 also using a benzodiazepine and 4 out of 10 using cannabis. Until 1998, 100% of patients obtained zolpidem through medical prescriptions; since 2001 nearly 15%–20% of users bought it through street deals. A 2003 survey of 297 patients admitted to addiction treatment sites in the United 136 Kingdom found that while zopiclone was used by many more subjects than zolpidem (53. Eszopiclone, zaleplon, zolpidem extended-release, and ramelteon have been in use for a shorter period than zolpidem and zaleplon, so there is less information about their effects over the long term.
