Internet based multicenter study for thoracolumbar injuries: a new concept and preliminary results

This article reports about the internet based, second multicenter study (MCS II) of the spine study group (AG WS) of the German trauma association (DGU). It represents a continuation of the first study conducted between the years 1994 and 1996 (MCS I). For the purpose of one common, centralised data capture methodology, a newly developed internet-based data collection system ( http://www.memdoc.org ) of the Institute for Evaluative Research in Orthopaedic Surgery of the University of Bern was used. The aim of this first publication on the MCS II was to describe in detail the new method of data collection and the structure of the developed data base system, via internet. The goal of the study was the assessment of the current state of treatment for fresh traumatic injuries of the thoracolumbar spine in the German speaking part of Europe. For that reason, we intended to collect large number of cases and representative, valid information about the radiographic, clinical and subjective treatment outcomes. Thanks to the new study design of MCS II, not only the common surgical treatment concepts, but also the new and constantly broadening spectrum of spine surgery, i.e. vertebro-/kyphoplasty, computer assisted surgery and navigation, minimal-invasive, and endoscopic techniques, documented and evaluated. We present a first statistical overview and preliminary analysis of 18 centers from Germany and Austria that participated in MCS II. A real time data capture at source was made possible by the constant availability of the data collection system via internet access. Following the principle of an application service provider, software, questionnaires and validation routines are located on a central server, which is accessed from the periphery (hospitals) by means of standard Internet browsers. By that, costly and time consuming software installation and maintenance of local data repositories are avoided and, more importantly, cumbersome migration of data into one integrated database becomes obsolete. Finally, this set-up also replaces traditional systems wherein paper questionnaires were mailed to the central study office and entered by hand whereby incomplete or incorrect forms always represent a resource consuming problem and source of error. With the new study concept and the expanded inclusion criteria of MCS II 1, 251 case histories with admission and surgical data were collected. This remarkable number of interventions documented during 24 months represents an increase of 183% compared to the previously conducted MCS I. The concept and technical feasibility of the MEMdoc data collection system was proven, as the participants of the MCS II succeeded in collecting data ever published on the largest series of patients with spinal injuries treated within a 2 year period.

Internetbasierte geleitete Selbsthilfeansätze bei Angststörungen und Depressionen

Das Spektrum internetbasierter psychologischer Behandlungsangebote bei psychischen Problemen und Erkrankungen bewegt sich zwischen webbasierten Selbsthilfeprogrammen, die das Internet als Informationsmedium verwenden, und Email-, Chat- und Video-Therapien, in welchen das Internet zu Kommunikationszwecken zwischen Hilfesuchenden und Professionellen genutzt wird. Dieser Beitrag fokussiert auf eine Beratungs- und Therapieform, die die Möglichkeiten des Internets als Informations- und Kommunikationsmedium in sogenannten geleiteten Selbsthilfeansätzen kombiniert. Internetbasierte geleitete Selbsthilfeansätze, in welchen Klienten während der Bearbeitung eines Selbsthilfeprogramms von Therapeuten via Internet (z.B. Email) unterstützt werden, wurden in den letzten Jahren intensiv erforscht. Im Bereich von Angststörungen und Depressionen liegen besonders viele Studien vor. Verschiedene Forschergruppen haben hier in der Regel große Behandlungseffekte gefunden, die mit der Wirkung von Face-to-Face-Therapien vergleichbar sind. In diesem Beitrag wird der geleitete Selbsthilfeansatz dargestellt und die empirische Evidenz diskutiert.

Internetbasierte Psychotherapie

In den letzten Jahren wurde ein breites Spektrum an internet- bzw. technikbasierten Interventionen bei psychischen Problemen und Erkrankungen entwickelt. Angebote reichen von internetbasierten und DVD-vermittelten Selbsthilfeprogrammen zu E-Mail-Therapien, von Prävention über Beratung und Behandlung zu Nachsorge- und Rückfallpräventionsprogrammen, und von Interventionen, die computervermittelte Teile in hauptsächlich Face-to-Face durchgeführte Interventionen integrieren bis hin zu vollständig via Internet durchgeführte Therapien. In diesem Workshop werden verschiedene Ansätze und empirische Befunde erläutert. Anhand konkreter Beispiele werden Vor- und Nachteile, sowie Qualitätsmerkmale entsprechender Angebote diskutiert.

Internetbasierte Interventionen bei psychischen Störungen

Der Einsatz und die Erforschung internetbasierter Interventionen bei psychischen Störungen haben in den letzten Jahren rapide zugenommen. In einigen Ländern wurde die Behandlung via Internet bereits in die psychosoziale Versorgung integriert. Der Band bietet einen Überblick über verschiedene Ansätze der Online-Therapie und -Beratung und zeigt auf, wie die Interventionen bei der Prävention, Therapie und Nachsorge psychischer Störungen praktisch umgesetzt werden können. Zunächst geht der Band auf die Vor- und Nachteile, Besonderheiten, auf rechtliche und ethische Aspekte sowie auf Qualitätskriterien von Internet-Interventionen ein. In knapper Form werden Theorien und Modelle der computervermittelten Kommunikation vorgestellt und deren Implikationen für die Praxis der Online-Beratung und -Therapie aufgezeigt. Es folgen konkrete Anleitungen zum diagnostischen Vorgehen, wie z.B. zum Einsatz von Online-Fragebogendiagnostik und zur Durchführung diagnostischer Interviews per Telefon. Anhand von Beispielen werden verschiedene internetbasierte Interventionen, wie z.B. webbasierte Selbsthilfeprogramme, E-Mail-, Chat-Therapie oder die Therapie via Videokonferenzsysteme, die entweder vollständig via Internet oder ergänzend zu traditionellen Psychotherapien und Beratungen realisiert werden können, vorgestellt. Abschließend werden Behandlungsempfehlungen gegeben und wichtige Fragen, die sich bei der konkreten Ausgestaltung dieser neuen Behandlungsform stellen, geklärt.

Simple training tool is insufficient for appropriate diagnosis and treatment of malnutrition: A pre-post intervention study in a tertiary center.

OBJECTIVES To improve malnutrition awareness and management in our department of general internal medicine; to assess patients' nutritional risk; and to evaluate whether an online educational program leads to an increase in basic knowledge and more frequent nutritional therapies. METHODS A prospective pre-post intervention study at a university department of general internal medicine was conducted. Nutritional screening using Nutritional Risk Score 2002 (NRS 2002) was performed, and prescriptions of nutritional therapies were assessed. The intervention included an online learning program and a pocket card for all residents, who had to fill in a multiple-choice questions (MCQ) test about basic nutritional knowledge before and after the intervention. RESULTS A total of 342 patients were included in the preintervention phase, and 300 were in the postintervention phase. In the preintervention phase, 54.1% were at nutritional risk (NRS 2002 ≥3) compared with 61.7% in the postintervention phase. There was no increase in the prescription of nutritional therapies (18.7% versus 17.0%). Forty-nine and 41 residents (response rate 58% and 48%) filled in the MCQ test before and after the intervention, respectively. The mean percentage of correct answers was 55.6% and 59.43%, respectively (which was not significant). Fifty of 84 residents completed the online program. The residents who participated in the whole program scored higher on the second MCQ test (63% versus 55% correct answers, P = 0.031). CONCLUSIONS Despite a high ratio of malnourished patients, the nutritional intervention, as assessed by nutritional prescriptions, is insufficient. However, the simple educational program via Internet and usage of NRS 2002 pocket cards did not improve either malnutrition awareness or nutritional treatment. More sophisticated educational systems to fight malnutrition are necessary.

Quality evaluation of the available Internet information regarding pain during orthodontic treatment

OBJECTIVE To investigate the quality of the data disseminated via the Internet regarding pain experienced by orthodontic patients. MATERIALS AND METHODS A systematic online search was performed for 'orthodontic pain' and 'braces pain' separately using five search engines. The first 25 results from each search term-engine combination were pooled for analysis. After excluding advertising sites, discussion groups, video feeds, and links to scientific articles, 25 Web pages were evaluated in terms of accuracy, readability, accessibility, usability, and reliability using recommended research methodology; reference textbook material, the Flesch Reading Ease Score; and the LIDA instrument. Author and information details were also recorded. RESULTS Overall, the results indicated a variable quality of the available informational material. Although the readability of the Web sites was generally acceptable, the individual LIDA categories were rated of medium or low quality, with average scores ranging from 16.9% to 86.2%. The orthodontic relevance of the Web sites was not accompanied by the highest assessment results, and vice versa. CONCLUSIONS The quality of the orthodontic pain information cited by Web sources appears to be highly variable. Further structural development of health information technology along with public referral to reliable sources by specialists are recommended.

Internet-based individually versus group guided self-help treatment for social anxiety disorder: protocol of a randomized controlled trial

BACKGROUND: Social anxiety disorder (SAD) is one of the most common mental disorders and causes subjective suffering and economic burden worldwide. Although effective treatments are available, a lot of cases go untreated. Internet-based self-help is a low-threshold and flexible treatment alternative for SAD. Various studies have already shown that internet-based self-help can be effective to reduce social phobic symptoms significantly. Most of the interventions tested include therapist support, whereas the role of peer support within internet-based self-help has not yet been fully understood. There is evidence suggesting that patients' mutual exchange via integrated discussion forums can increase the efficacy of internet-based treatments. This study aims at investigating the added value of therapist-guided group support on the treatment outcome of internet-based self-help for SAD. METHODS/DESIGN: The study is conducted as a randomized controlled trial. A total of 150 adults with a diagnosis of SAD are randomly assigned to either a waiting-list control group or one of the active conditions. The participants in the two active conditions use the same internet-based self-help program, either with individual support by a psychologist or therapist-guided group support. In the group guided condition, participants can communicate with each other via an integrated, protected discussion forum. Subjects are recruited via topic related websites and links; diagnostic status will be assessed with a telephone interview. The primary outcome variables are symptoms of SAD and diagnostic status after the intervention. Secondary endpoints are general symptomology, depression, quality of life, as well as the primary outcome variables 6 months later. Furthermore, process variables such as group processes, the change in symptoms and working alliance will be studied. DISCUSSION: The results of this study should indicate whether group-guided support could enhance the efficacy of an internet-based self-help treatment for SAD. This novel treatment format, if shown effective, could represent a cost-effective option and could further be modified to treat other conditions, as well.

A sorrow shared is a sorrow halved? Internet-based group therapy versus individual therapy for social anxiety disorder: A randomized controlled trial

Purpose: Social anxiety disorder is one of the most researched conditions in the field of Internet-based self-help. Various studies have shown that cognitive-behavioral treatments can be efficacious to reduce social phobic symptoms. Most of the interventions tested include some form of support, whereas the efficacy of a web-based group format has yet to be investigated. The present study aims at investigating the possible added value of therapist-guided group support in an Internet-based guided self-help treatment for SAD. Methods: A total of 150 adults with a diagnosis of SAD are randomly assigned to either a wait-list control group or one of two active treatment conditions. Participants in the two active conditions use the same Internet-based self-help program, either with individual guidance by a therapist or with the support of a therapist-guided group of 6 individuals. In the group condition, participants communicate with each other via an integrated, protected discussion forum. The primary outcome variables are symptoms of SAD and diagnostic status immediately after the intervention (12 weeks) and at 6-month follow-up. Secondary endpoints are general symptomatology, depression, quality of life and adherence to treatment. Furthermore, process variables such as group processes and the working alliance are studied. Results: Results are currently being analyzed. Results at post-treatment will be presented and discussed. Potential moderating and mediating variables of treatment success will be addressed. Conclusion: The results of this study should indicate whether therapist-guided group support could enhance the efficacy of an internet based self-help treatment for SAD. This novel treatment format, if shown efficacious, could represent a cost-effective option and could be further modified to treat other conditions.

Efficacy of an Internet-based, individually tailored smoking cessation program: A randomized trial

Introduction: Self-help computer-based programs are easily accessible and cost-effective interventions with a great recruitment potential. However, each program is different and results of meta-analyses may not apply to each new program; therefore, evaluations of new programs are warranted. The aim of this study was to assess the marginal efficacy of a computer-based, individually tailored program (the Coach) over and above the use of a comprehensive Internet smoking cessation website. Methods: A two-group randomized controlled trial was conducted. The control group only accessed the website, whereas the intervention group received the Coach in addition. Follow-up was conducted by e-mail after three and six months (self-administrated questionnaires). Of 1120 participants, 579 (51.7%) responded after three months and 436 (38.9%) after six months. The primary outcome was self-reported smoking abstinence over four weeks. Results: Counting dropouts as smokers, there were no statistically significant differences between intervention and control groups in smoking cessation rates after three months (20.2% vs. 17.5%, p¼0.25, odds ratio (OR)¼1.20) and six months (17% vs. 15.5%, p¼0.52, OR¼1.12). Excluding dropouts from the analysis, there were statistically significant differences after three months (42% vs. 31.6%, p¼0.01, OR¼1.57), but not after six months (46.1% vs. 37.8%, p¼0.081, OR¼1.41). The program also significantly increased motivation to quit after three months and self-efficacy after three and six months. Discussion: An individually tailored program delivered via the Internet and by e-mail in addition to a smoking cessation website did not significantly increase smoking cessation rates, but it increased motivation to quit and self-efficacy.
