Experimental studies to improve the reliability and validity of regulatory judgments on health care in the Netherlands: a randomized controlled trial and before and after case study

Rationale, aims and objectives We examined the effect of two interventions on both the reliability and validity of regulatory judgments: adjusting the regulatory instrument and attending a consensus meeting. Method We adjusted the regulatory instrument. With a randomized controlled trial (RCT) we examined the effect of the adjustments we made to the instrument. In the consensus meeting inspectors discussed cases and had to reach consensus about the order of the cases. We used a before and after case study to assess the effect of the consensus meeting. We compared the judgments assigned in the RCT with the unadjusted instrument with the judgments assigned with the unadjusted instrument after the consensus meeting. Moreover we explored the effect of increasing the number of inspectors per regulatory visit based on the estimates of the two interventions. Results The consensus meeting improved the agreement between inspectors; the variance between inspectors was smallest (0.03) and the reliability coefficient was highest (0.59). Validity is assessed by examining the relation between the assigned judgments and the corporate standard and expressed by a correlation coefficient. This coefficient was highest after the consensus meeting (0.48). Adjustment of the instrument did not increase reliability and validity coefficients. Conclusions Participating in a consensus meeting improved reliability and validity. Increasing the number of inspectors resulted in both higher reliability and validity values. Organizing consensus meetings and increasing the number of inspectors per regulatory visit seem to be valuable interventions for improving regulatory judgment

WeHeart:A Personalized Recommendation Device for Physical Activity Encouragement in Cardiac Rehabilitation

We introduce WeHeart, a personalized recommendation device that aims to gradually increase physical activity levels in cardiac rehabilitation. The importance of physical activity in cardiac rehabilitation as a means of reducing associated morbidity and mortality rates is well-established. However, forming physical activity habits is a challenge, and the approach varies depending on individual preferences. Our solution employs a Random Forest classification model that combines both measured and self-reported data to provide personalized recommendations. We also propose to make use of Explainable AI to improve transparency and foster trust.</p

Het ene oordeel is het andere niet: Kwantitatieve analyse van de variatie bij IGZ-Inspecteurs

DOEL\ud Onderzoek naar de variatie in oordelen tussen inspecteurs van de Inspectie voor de Gezondheidszorg (IGZ) in het systeem van gefaseerd toezicht op de verpleeghuiszorg en naar de relatie tussen het type oordeel en de aan- of afwezigheid van onderbouwing daarbij.\ud \ud OPZET \ud Descriptief, kwantitatief, retrospectief.\ud \ud METHODE\ud In totaal werden 4914 oordelen met bijbehorende onderbouwingen van 26 inspecteurs uit 182 toezichtrapporten geanalyseerd. De oordelen waren in 2005 en 2006 gegeven op 25 criteria voor verantwoorde zorg in verpleeghuizen. Om de inspecteurs en hun oordelen over verschillende instellingen te kunnen vergelijken, werd met covariantieanalyse statistisch gecorrigeerd voor instellingskenmerken.\ud \ud RESULTATEN\ud Er waren statistisch significante verschillen in beoordeling tussen de inspecteurs. Na correctie voor instellingskenmerken bleven voor 14 van de 25 criteria significante verschillen bestaan. Tevens bleek de aanwezigheid van een onderbouwing bij een oordeel zowel afhankelijk te zijn van de inspecteur als van het gegeven oordeel.\ud \ud CONCLUSIE \ud Beoordelaarsverschillen tussen inspecteurs spelen een rol in de tweede fase van het gefaseerd toezicht op de verpleeghuizen. De IGZ zal resultaten van dit onderzoek gebruiken om haar toezicht verder te ontwikkelen

A Zero-Gravity Instrument to Study Low Velocity Collisions of Fragile Particles at Low Temperatures

We discuss the design, operation, and performance of a vacuum setup constructed for use in zero (or reduced) gravity conditions to initiate collisions of fragile millimeter-sized particles at low velocity and temperature. Such particles are typically found in many astronomical settings and in regions of planet formation. The instrument has participated in four parabolic flight campaigns to date, operating for a total of 2.4 hours in reduced gravity conditions and successfully recording over 300 separate collisions of loosely packed dust aggregates and ice samples. The imparted particle velocities achieved range from 0.03-0.28 m s^-1 and a high-speed, high-resolution camera captures the events at 107 frames per second from two viewing angles separated by either 48.8 or 60.0 degrees. The particles can be stored inside the experiment vacuum chamber at temperatures of 80-300 K for several uninterrupted hours using a built-in thermal accumulation system. The copper structure allows cooling down to cryogenic temperatures before commencement of the experiments. Throughout the parabolic flight campaigns, add-ons and modifications have been made, illustrating the instrument flexibility in the study of small particle collisions.Comment: D. M. Salter, D.
