  Objective: To assess the cost-effectiveness of a single treatment session of acupuncture, when applied in addition to usual care for acute low back pain (ALBP). Methods: Secondary analysis of a multicentre randomised controlled trial in Norwegian general practice. In total, 171 participants with ALBP ⩽14 days were randomised to a control group (CG) receiving usual care or to an acupuncture group (AG) receiving one additional session of Western medical acupuncture alongside usual care. Primary outcome measures for this cost-effectiveness analysis were quality-adjusted life years (QALYs), health care costs and societal costs at days 28 and 365, the incremental cost-effectiveness ratio (ICER) and net monetary benefit (NMB). The NMB was calculated on the basis of the Norwegian cost-effectiveness threshold of NOK 275,000 (USD 35,628) per QALY gained. Missing data were replaced by multiple chained imputation. Results: Eighty-six participants in the CG and 81 in the AG were included in the analysis. We found no QALY gain at day 28. At day 365, the incremental QALY of 0.035 was statistically significant. The differences in health care costs and societal costs were not statistically significant. Three out of four calculations led to negative ICERs (cost saving) and positive NMBs. For the health care perspective at day 365, the ICER was USD –568 per QALY and the NMB was USD 1265, with 95.9% probability of acupuncture being cost-effective. Conclusion: To our knowledge, this is the first cost-effectiveness analysis of acupuncture for ALBP. The findings indicate that acupuncture may be cost-effective from a 1-year perspective, but more studies are needed. Trial registration number: NCT01439412 (ClinicalTrials.gov).

  Background: Symptoms of depression are frequent in youth and may develop into more severe mood disorders, suggesting interventions should take place during adolescence. However, young people tend not to share mental problems with friends, family, caregivers, or professionals. Many receive misleading information when searching the internet. Among several attempts to create mental health services for adolescents, technological information platforms based on psychoeducation show promising results. Such development rests on established theories and therapeutic models. To fulfill the therapeutic potential of psychoeducation in health technologies, we lack data-driven research on young peoples’ demand for information about depression. Objective: Our objective is to gain knowledge about what information is relevant to adolescents with symptoms of depression. From this knowledge, we can develop a population-specific psychoeducation for use in different technology platforms. Methods: We conducted a qualitative, constructivist-oriented content analysis of questions submitted by adolescents aged 16-20 years to an online public information service. A sample of 100 posts containing questions on depression were randomly selected from a total of 870. For analysis, we developed an a priori codebook from the main information topics of existing psychoeducational programs on youth depression. The distribution of topic prevalence in the total volume of posts containing questions on depression was calculated. Results: With a 95% confidence level and a ±9.2% margin of error, the distribution analysis revealed the following categories to be the most prevalent among adolescents seeking advice about depression: self-management (33%, 61/180), etiology (20%, 36/180), and therapy (20%, 36/180). Self-management concerned subcategories on coping in general and how to open to friends, family, and caregivers. The therapy topic concerned therapy options, prognosis, where to seek help, and how to open up to a professional. We also found young people dichotomizing therapy and self-management as opposite entities. The etiology topic concerned stressors and risk factors. The diagnosis category was less frequently referred to (9%, 17/180). Conclusions: Self-management, etiology, and therapy are the most prevalent categories among adolescents seeking advice about depression. Young people also dichotomize therapy and self-management as opposite entities. Future research should focus on measures to promote self-management, measures to stimulate expectations of self-efficacy, information about etiology, and information about diagnosis to improve self-monitoring skills, enhancing relapse prevention.

  Objectives Previously, we identified a 10-year cohort of protocols from applications to the Norwegian Medicines Agency 1998–2007, consisting of 196 drug trials in general practice. The aim of this study was to examine whether trial results were published and whether trial funding and conflicts of interest were reported. Design Cohort study of trials with systematic searches for published results. Setting Clinical drug trials in Norwegian general practice. Methods We performed systematic literature searches of MEDLINE, Embase and CENTRAL to identify publications originating from each trial using characteristics such as test drug, comparator and patient groups as search terms. When no publication was identified, we contacted trial sponsors for information regarding trial completion and reference to any publications. Main outcome measures We determined the frequency of publication of trial results and trial characteristics associated with publication of results. Results Of the 196 trials, 5 were never started. Of the remaining 191 trials, 71% had results published in a journal, 11% had results publicly available elsewhere and 18% of trials had no results available. Publication was more common among trials with an active comparator drug (χ2 test, p=0.040), with a larger number of patients (total sample size≥median, p=0.010) and with a longer trial period (duration≥median, p=0.025). Trial funding was reported in 85% of publications and increased over time, as did reporting of conflicts of interest among authors. Among the 134 main journal articles from the trials, 60% presented statistically significant results for the investigational drug, and the conclusion of the article was favourable towards the test drug in 78% of papers. Conclusions We did not identify any journal publication of results for 29% of the general practice drug trials. Trials with an active comparator, larger and longer trials were more likely to be published.

  Kunnskap om effekten av medisinsk behandling fremskaffes i kliniske studier. Godt planlagte og gjennomførte randomiserte, placebokontrollerte studier tillegges størst vekt når data skal vurderes. De datamengdene vi besitter når det gjelder forskjellige behandlinger kan oppsummeres i oversikter eller terapianbefalinger som ofte blir normative for klinisk praksis. Dette stiller store krav til evalueringsprosedyrene. I denne oversiktsartikkelen diskuteres i innledningen noen eksempler på at kunnskapsgrunnlaget er blitt feiltolket. Deretter omtales kvalitetskriterier som legges til grunn i vurderingen av data, og den metodologiske basis for meta-analyser. Usikkerhetsmomenter og potensielle fallgruver ved bruk av meta-analyser omtales. Meta-analysens fortrinn eksemplifiseres ved bruk av data om behandling av korsryggsmerter, hvor det nylig er utarbeidet kliniske retningslinjer som etter vår oppfatning er beheftet med feil eller mangler. Meta-analysen har vesentlige fortrinn fremfor mindre formaliserte metoder for oppsummering av kunnskap om terapi ved sykdom. Data on the effects of medical therapies are available from clinical studies. Well planned and executed randomised, placebo-controlled studies are given the highest level of evidence when study results are reviewed. The available body of data on different therapies lend themselves to synthesis in clinical overviews or therapy recommendations that regularly achieve status as normative for clinical practice. This warrants caution and rigour as far as the underlying procedures are concerned. The current review encompasses a brief discussion of previous failures of pharmacovigilance, including the thalidomide disaster and the COX-2 debacle. The quality criteria for data evaluation and the methodological basis for meta-analyses are presented. Possible sources of error in meta-analyses, such as different reporting of effects, publication bias, heterogeneity, conflicts of interest and problems with evaluation of side effects, are discussed. The advantages of meta-analysis are exemplified with data on therapy of lower back pain, which recently has been subjected to clinical practice guidelines that, in our view, have several shortcomings. Meta-analyses have significant advantages over less formalised methods for the evaluation of the current state of knowledge of therapeutic alternatives.

  BACKGROUND: Pain is the most debilitating symptom in osteoarthritis of the knee (OAK). AIM AND METHODS: To determine the short-term pain-relieving effects of seven commonly used pharmacological agents for OAK pain by performing a systematic review of randomised placebo-controlled trials. RESULTS: In total, 14,060 patients in 63 trials were evaluated. Opioids and oral NSAIDs therapy in patients with moderate to severe pain (mean baseline 64.3 and 72.8mm on VAS respectively) had maximum efficacies compared to placebo at 2-4 weeks of 10.5mm [95% CI: 7.4-13.7] and 10.2mm [95% CI: 8.8-11.2] respectively. The efficacy of opioids may be inflated by high withdrawal rates (24-50%) and "best-case" scenarios reported in intention-to-treat analyses. In patients with moderate pain scores on VAS (mean range from 51 to 57mm), intra-articular steroid injections and topical NSAIDs had maximum efficacies at 1-3 weeks of 14.5mm [95% CI: 9.7-19.2] and 11.6 mm [95% CI: 7.4-15.7], respectively. Paracetamol, glucosamin sulphate and chondroitin sulphate had maximum mean efficacies at 1-4 weeks of only 4.7mm or lower. Heterogeneity tests revealed that best efficacy values of topical NSAIDs may be slightly deflated, while data for oral NSAIDs may be slightly inflated due to probable patient selection bias. CONCLUSION: Clinical effects from pharmacological interventions in OAK are small and limited to the first 2-3 weeks after start of treatment. The pain-relieving effects over placebo in OAK are smaller than the patient-reported thresholds for relevant improvement.

  Conclusions: The results of this CDSR was not robust and seems to be colored by questionable selections or omissions. For alternative pain therapies, it should be considered if lack of expertise oil therapy mechanisms, or conflicts of interests with competing pain drug manufacturers, may bias conclusions. Review groups should recruit a balanced mix of current views and expertise and expand the use of sensitivity analyses to improve quality of CDSRs in areas of controversy.

Vis sammendrag

  OBJECTIVE: The aim of this study was to test if a conclusion in a systematic review of low-level laser therapy (LLLT) for osteoarthritis from the Cochrane Library was valid and robust. BACKGROUND DATA: Health policy decisions often rely on conclusions from the Cochrane Database of Systematic Reviews for approval of new therapies, although their validity for controversial non-pharmacological treatment has been questioned. METHODS: Validity was tested against a nine-item checklist for systematic reviews. Review selections were analyzed for possible discrepancies between trial and review reports, and omissions of relevant trials and data. Alternative data from discrepancies and omissions were then imputed in a sensitivity analysis, to test if review conclusions were robust. RESULTS: Only clinicians who had performed LLLT trials with negative results were invited into the review group. Review quality was sound in areas of literature search and methodological assessments, and some of the limitations were mentioned. The statistical analysis held 18 questionable selections such as omissions of trials, data, and subgroup analyses. These selections systematically favored the negative review conclusion. Without altering the review protocol, the sensitivity analysis of combined results changed to significantly positive for continuous and categorical data when data from all included trials were combined. Further sensitivity analyses with inclusion of valid non-included trials, performance of missing follow-up, and subgroup analyses revealed consistent and highly significant results in favor of active LLLT. CONCLUSIONS: In this example, the Cochrane review conclusion was neither robust nor valid. Representation of experts and different views on efficacy in the review group and extensive use of sensitivity analyses could probably improve quality control of reviews in areas of controversy

  OBJECTIVE: To estimate the analgesic efficacy of non-steroidal anti-inflammatory drugs (NSAIDs), including selective cyclo-oxygenase-2 inhibitors (coxibs), in patients with osteoarthritis of the knee. DESIGN: Systematic review and meta-analysis of randomised placebo controlled trials. STUDIES REVIEWED: 23 trials including 10 845 patients, median age of 62.5 years. 7807 patients received adequate doses of NSAIDs and 3038received placebo. The mean weighted baseline pain score was 64.2 mm on 100 mm visual analogue scale (VAS), and average duration of symptoms was 8.2 years. MAIN OUTCOME MEASURE: Change in overall intensity of pain. RESULTS: Methodological quality of trials was acceptable, but 13 trials excluded patients before randomisation if they did not respond to NSAIDs. One trial provided long term data for pain that showed no significant effect of NSAIDs compared with placebo at one to four years. The pooled difference for pain on visual analogue scale in all included trials was 10.1 mm (95% confidence interval 7.4 to 12.8) or 15.6% better than placebo after 2-13 weeks. Theresults were heterogeneous, and the effect size for pain reduction was 0.32 (0.24 to 0.39) in a random effects model. In 10 trials that did not exclude non-responders to NSAID treatment the results were homogeneous, with an effect size for pain reduction of 0.23 (0.15 to 0.31). CONCLUSION: NSAIDs can reduce short term pain in osteoarthritis of the knee slightly better than placebo, but the current analysis does not supportlong term use of NSAIDs for this condition. As serious adverse effects are associated with oral NSAIDs, only limited use can be recommended

  Background. Kauppila and co-workers published in 1982 a detrusor inst ability score (DIS) for women with urinary incontinence. The aim of t his study was to determine the validity of the DIS in an outpatient c linic for urogynaecology. Methods. The DIS questionnaire was incorpor ated as part of an independent history at the first consultation. The DIS was comparedwith clinical diagnosis in 250 patients consecutivel y referred for evaluation. Sensitivity, specificity, positive predict ive value (PPV), negative predictive value (NPV) and overallaccuracy of the DIS in diagnosing genuine stress incontinence (GSI) were calcu lated using the gynaecologist's clinical diagnosis based on urodynami c findings as the gold standard. AnROC- curve was constructed for det ermining the optimum cut-off point for the DIS for women with GSI. Re sults. A cut-off point at 7 for the DIS, yielded sensitivity=0.77, sp ecificity=0.52,PPV=0.74, NPV=0.52 and an overall accuracy=0.68. Optim um cut-off point for GSI according to the ROC-curve was at a DIS-valu e of 5, yielding sensitivity=0.60, specificity=0.77, PPV =0. 82, NPV= 0.52 and overall accuracy=0.66. Conclusions. A cut-off point at 7 dia gnosed 159 women (64%) as having GSI, 41 of them (16% of 250) having a false positive DIS. Similarly, a c ut-off point at 5 diagnosed 112 women (45%) as having GSI, 20 of them (8% of 250) having a false posi tive DIS. These women, if otherwise feasible and indicated, might per haps undergo continence surgery without preoperative urodynamics. A l ower cut-off point than originally proposed ought therefore to be use d if the DIS is to become a useful preoperative tool fo r this kind o f surgery.

  In a recent overview encompassing systematic reviews and randomized trials of pharmacotherapy in low back pain (LBP), the authors concluded that there is good evidence that acetaminophen, NSAID and muscle relaxants provide moderate pain relief in acute LBP (1). In another clinical guideline article in the same issue of the Annals (2), the recommended indications for acetaminophen and NSAIDs are extended to include chronic LBP, whereas tramadol, opiods, and benzodiazepines are recommended both in acute and chronic LBP despite the lack of “good” or even “fair” evidence. The methodology used by the authors to review the literature may be flawed in the sense that it merely reiterates what other reviewers have published previously. The current overview does not address crucial differences in focus and protocols of the included reviews, and fails to adequately assess the randomized controlled trials which are the primary sources for information. The criteria list which was used does not imply investigations of the primary sources (RCTs) or the correctness of the trial data cited in the systematic review. The quality assessment method here is inadequate to detect or handle data errors in the review. With multiple data errors, faulty method assessments or misclassification of trials, there is no operationalization of the consequences for method scores. Indeed, some reviewing errors may be grave enough to jeopardize the overreview conclusions completely, but the overview scoring system only opens for a reduction of a single point or two. Misinterpretation of data leads to erroneous conclusions, which in turn may propagate the myth of medication efficacy in LBP. Moreover, the involvement of individuals with industry relations in the making of guidelines is controverisal (3). Indeed, the declaration of conflicts of interest in the form of receiving honoraria from the pharmaceutical industry by principal authors of the clinical guidelines (2) is, in our view, of noteworthy and potentially derogatory significance.

  VG FØLGER Helse og medisin Urinveisplager kartlegges på nettet    Av MARIANNE HEEN JOHNSGÅRD (VG Nett) Seksjon for allmennmedisin ved universitetet i Bergen går nye veier for å samle inn informasjon til forskningsprosjekter. Ved hjelp av en nettbasert helseundersøkelse skal norske kvinners urinveisplager nå kartlegges. Tips en venn om denne saken! -Se dagens mest populære tips! Atle Klovning. Foto: SCANPIX   Få nyhetene om Helse og medisin først - abonnér på VG Nett Nyhetsbrev! Trykk her! Ifølge forsker Atle Klovning slår han og kollegaene hans to fluer i en smekk ved å bruke internett til å gjennomføre «Kvinneundersøkelsen 2002»: - Samtidig som vi får samlet inn informasjon om vannlatingsproblemer, får vi også testet ut weben som forskningsmedium, sier Klovning til VG Nett. - Det er lite kunnskap om datainnsamling på nettet, så vi prøver ut forskjellige kanaler. Jo flere kanaler vi får prøvd oss på, jo klarere blir det hvilke nettsteder som er representative for befolkningen, forteller forskeren. - Gjør forskning enklere Dataene som samles inn på nettet, skal sammenlignes med data som tidligere er blitt samlet inn i Nord-Trøndelag. På den måten håper forskerne å få et klarer bilde av hvordan internett fungerer i forhold til tradisjonelle metoder. - Datainnsamling på nettet vil kunne innebære en veldig forenkling i forskningssammenheng. Alt er allerede tastet inn i en database, og man kan begynne rett på databehandlingen, sier Klovning. Forskerne ved seksjon for allmennmedisin er positivt overrasket over responsen siden nettundersøkelsen ble lansert forrige uke: Godt over 100 svar kom inn i løpet av de tre første dagene. - Undersøkelsen vil legge ute et par uker til, avhengig av den videre responsen, sier Klovning til VG Nett. Klikk her hvis du vil delta i undersøkelsen! 300 000 kvinner rammet Det er ikke tilfeldig at nettundersøkelsen fokuserer på urinveisplager. Ifølge Atle Klovning har 300 000 norske kvinner denne typen problemer - en plage som få liker å snakke om: - Dette er et spennende og betydelig allmennmedisinsk problem, som mange opplever som tabubelagt. - Vi ønsker å kartlegge enkle metoder for å bedre situasjonen for disse kvinnene, forteller Klovning, som samarbeider med professor Steinar Hunskår og forsker Hogne Sandvik om dette prosjektet.
