BackgroundMany healthcare interventions are of complex nature, consisting of several interacting components. Complex interventions are often described inadequately. A reporting guideline for complex interventions was published in 2012 (Criteria for Reporting the Development and Evaluation of Complex Interventions in healthcare, CReDECI) and was recently checked for its practicability. The reporting guideline was developed following the recommendations of the EQUATOR network but excluding a formal consensus process. Therefore, a consensus process was initiated, to revise the reporting guideline.MethodsWe used a three-phase consensus process consisting of (1) a web-based feedback survey on the published reporting guideline, (2) a face-to-face consensus conference, and (3) a final online review and feedback round to create the revised CReDECI. The consensus process was organized and conducted via the REFLECTION network.ResultsA total of 45 attendees from 16 European countries took part in the face-to-face consensus conference. The revised reporting guideline (CReDECI 2) comprises 13 items on three stages: development, feasibility and piloting, and evaluation of a complex intervention. Each item is illustrated by an explanation and an example. In contrast with most of the available reporting guidelines, CReDECI 2 does not focus on a specific study design, to reflect the use of different qualitative and quantitative designs and methods in the development and evaluation of complex interventions.ConclusionsCReDECI 2 is a formally consented reporting guideline aiming to improve the reporting quality of the development and evaluation stages of complex interventions in healthcare. Since the guideline does not focus on a specific study design, design-specific reporting guidelines may additionally be used.Electronic supplementary materialThe online version of this article (doi:10.1186/s13063-015-0709-y) contains supplementary material, which is available to authorized users.
Context Despite unambiguous legal regulation and evidence for lack of effectiveness and safety, physical restraints are still frequently administered in nursing homes.Objective To reduce physical restraint prevalence in nursing homes using a guideline-and theory-based multicomponent intervention. Design, Setting, and ParticipantsCluster randomized controlled trial of 6 months' duration conducted in 2 German cities between February 2009 and April 2010. Nursing homes were eligible if they had 20% or more residents with physical restraints. Using external concealed randomization, 18 nursing home clusters were included in the intervention group (2283 residents) and 18 in the control group (2166 residents).Intervention The intervention was based on a specifically developed evidencebased guideline and applied the theory of planned behavior. Components were group sessions for all nursing staff; additional training for nominated key nurses; and supportive material for nurses, residents, relatives, and legal guardians. Control group clusters received standard information. Main Outcomes MeasuresPrimary outcome was percentage of residents with physical restraints (bilateral bed rails, belts, fixed tables, and other measures limiting free body movement) at 6 months, assessed through direct unannounced observation by blinded investigators on 3 occasions during 1 day. Secondary outcomes included restraint use at 3 months, falls, fall-related fractures, and psychotropic medication prescriptions. ResultsAll nursing homes completed the study and all residents were included in the analysis. At baseline, 30.6% of control group residents had physical restraints vs 31.5% of intervention group residents. At 6 months, rates were 29.1% vs 22.6%, respectively, a difference of 6.5% (95% CI, 0.6% to 12.4%; cluster-adjusted odds ratio, 0.71; 95% CI, 0.52 to 0.97; P=.03). All physical restraint measures were used less frequently in the intervention group. Rates were stable from 3 to 6 months. There were no statistically significant differences in falls, fall-related fractures, and psychotropic medication prescriptions. ConclusionA guideline-and theory-based multicomponent intervention compared with standard information reduced physical restraint use in nursing homes.
Patients with MS claimed autonomous roles in their health care decisions. The weak correlation between knowledge and preferences for active roles implicates that other factors largely influence role preferences.
Effective restraint minimisation approaches are urgently warranted. An evidence-based guideline may overcome centre differences towards a restraint-free nursing home care.
ObjectivePatient involvement into medical decisions as conceived in the shared decision making method (SDM) is essential in evidence based medicine. However, it is not conclusively evident how best to define, realize and evaluate involvement to enable patients making informed choices. We aimed at investigating the ability of four measures to indicate patient involvement. While use and reporting of these instruments might imply wide overlap regarding the addressed constructs this assumption seems questionable with respect to the diversity of the perspectives from which the assessments are administered.MethodsThe study investigated a nested cohort (N = 79) of a randomized trial evaluating a patient decision aid on immunotherapy for multiple sclerosis. Convergent validities were calculated between observer ratings of videotaped physician-patient consultations (OPTION) and patients' perceptions of the communication (Shared Decision Making Questionnaire, Control Preference Scale & Decisional Conflict Scale).ResultsOPTION reliability was high to excellent. Communication performance was low according to OPTION and high according to the three patient administered measures. No correlations were found between observer and patient judges, neither for means nor for single items. Patient report measures showed some moderate correlations.ConclusionExisting SDM measures do not refer to a single construct. A gold standard is missing to decide whether any of these measures has the potential to indicate patient involvement.Practice ImplicationsPronounced heterogeneity of the underpinning constructs implies difficulties regarding the interpretation of existing evidence on the efficacy of SDM. Consideration of communication theory and basic definitions of SDM would recommend an inter-subjective focus of measurement.Trial RegistrationControlled-Trials.com ISRCTN25267500.
STARDdem is an implementation of the STARD statement in which the original checklist is elaborated and supplemented with guidance pertinent to studies of cognitive disorders. Its adoption is expected to increase transparency, enable more effective evaluation of diagnostic tests in Alzheimer disease and dementia, contribute to greater adherence to methodologic standards, and advance the development of Alzheimer biomarkers.
BackgroundThe wide scale permeation of health care by the shared decision making concept (SDM) reflects its relevance and advanced stage of development. An increasing number of studies evaluating the efficacy of SDM use instruments based on various sub-constructs administered from different viewpoints. However, as the concept has never been captured in operable core definition it is quite difficult to link these parts of evidence.This study aims at investigating interrelations of SDM indicators administered from different perspectives.MethodA comprehensive inventory was developed mapping judgements from different perspectives (observer, doctor, patient) and constructs (behavior, perception) referring to three units (doctor, patient, doctor-patient-dyad) and an identical set of SDM-indicators. The inventory adopted the existing approaches, but added additional observer foci (patient and doctor-patient-dyad) and relevant indicators hitherto neglected by existing instruments. The complete inventory comprising a doctor-patient-questionnaire and an observer-instrument was applied to 40 decision consultations from 10 physicians from different medical fields. Convergent validities were calculated on the basis of Pearson correlation coefficients.ResultsReliabilities for all scales were high to excellent. No correlations were found between observer and patients or physicians neither for means nor for single items. Judgements of doctors and patients were moderately related. Correlations between the observer scales and within the subjective perspectives were high. Inter-perspective agreement was not related to SDM performance or patient activity.ConclusionThe study demonstrates the contribution to involvement made by each of the relevant perspectives and emphasizes the need for an inter-subjective approach regarding SDM measurement.
