The 2010 expansion of activity-based hospital payment in Israel: an evaluation of effects at the ward level

Waitzberg, Ruth ; Quentin, Wilm ; Daniels, Elad ; Perman, Vadim ; Brammli-Greenberg, Shuli ; Busse, Reinhard ; Greenberg, Dan (2019-05-08)

Background: In 2010, Israel intensified its adoption of Procedure-Related Group (PRG) based hospital payments, a local version of DRG (Diagnosis-related group). PRGs were created for certain procedures by clinical fields such as urology, orthopedics, and ophthalmology. Non-procedural hospitalizations and other specific procedures continued to be paid for as per-diems (PD). Whether this payment ...

Gesetzliche Mengensteuerung stationärer Leistungen - Krankenhausabrechnungsdaten als empirische Grundlage zur Analyse mengenanfälliger und nicht mengenanfälliger Leistungen

Spoden, Melissa (2019)

Hintergrund: Mit Einführung der fallpauschalierenden Diagnosis Related Groups (DRG) im Jahr 2003 wurde die bis dahin bestehende Kostenorientierung des deutschen Vergütungssystems von einer Leistungsorientierung abgelöst. Das DRG-System zielt mit seinen Anreizwirkungen auf eine effizientere Erbringung der Leistungen und ermöglicht gleichzeitig Leistungsverlagerungen zwischen den Kliniken. Neben ...

Towards incentivising integration: A typology of payments for integrated care

Stokes, Jonathan ; Struckmann, Verena ; Kristensen, Søren Rud ; Fuchs, Sabine ; van Ginneken, Ewout ; Tsiachristas, Apostoles ; Rutten-van Mölken, Maureen ; Sutton, Matt (2018-07-11)

Traditional provider payment mechanisms may not create appropriate incentives for integrating care. Alternative payment mechanisms, such as bundled payments, have been introduced without uniform definitions, and existing payment typologies are not suitable for describing them. We use a systematic review combined with example integrated care programmes identified from practice in the Horizon2020...

How to strengthen financing mechanism to promote care for people with multimorbidity in Europe?

Struckmann, Verena ; Quentin, Wilm ; Busse, Reinhard ; van Ginneken, Ewout (2017-11-22)

Payment mechanisms that take multiple chronic conditions into account and actually promote better integration of care are sadly lacking. This policy brief examines the steps policy makers must take if they are to adapt financing systems to support people with multimorbidity better. It looks at securing sustainable funding; options for upgrading payment mechanisms; and how financing mechanisms c...

The aims of the current scoping review were to i) identify relevant models and elements of integrated care for multi-morbidity and ii) to subsequently identify which of these models and elements are applied in integrated care programmes for mu...

Cross-Country Differences in Entrepreneurial Internationalization Tendencies: Evidence from Germany and Pakistan

Middermann, Laura H. ; Rashid, Lubna (2019-07-30)

Previous research has emphasized the importance of entrepreneurial characteristics for international entrepreneurship, hence the application of concepts such as entrepreneurial orientation and global mindset to the study of entrepreneurial internationalization tendencies (EIT). However, literature does not adequately address how EIT differ between countries or manifest in fragile country settin...

Examples from Blockchain Implementations in Logistics and Supply Chain Management: Exploring the Mindful Use of a New Technology

Verhoeven, Peter ; Sinn, Florian ; Herden, Tino T. (2018-09-11)

In the context of logistics, blockchain can help to increase end-to-end visibility along global supply chains. Thus, it can lead to improved tracking of goods and offer tamper-proof data to build trust among parties. Although a variety of blockchain use cases already exists, not all of them seem to rely on blockchain-specific features, but could rather be solved with traditional technologies. T...

Mobile phone-based health interventions for improved management of non-communicable diseases in Sub-Saharan Africa: challenges and opportunities for Ghana

Opoku, Daniel (2019)

Hintergrund: Nichtübertragbare Krankheiten (NCDs) sind allgemein als globale Krankheitslast bekannt, die die Gesundheitssysteme auf der ganzen Welt bedrohen. Um dieses große Problem der öffentlichen Gesundheit zu bekämpfen, wird der Einsatz von Informations- und Kommunikationstechnologien im Gesundheitswesen als Teil der Bemühungen untersucht, die erforderlich sind.

Boushey, Carol J. ; Spoden, Melissa ; Delp, Edward J. ; Zhu, Fengqing ; Bosch, Marc ; Ahmad, Ziad ; Shvetsov, Yurii B. ; DeLany, James P. ; Kerr, Deborah A. (2017-03-22)

The mobile Food Record (mFR) is an image-based dietary assessment method for mobile devices. The study primary aim was to test the accuracy of the mFR by comparing reported energy intake (rEI) to total energy expenditure (TEE) using the doubly labeled water (DLW) method. Usability of the mFR was assessed by questionnaires before and after the study. Participants were 45 community dwelling men a...

The reimbursement of new medical technologies in German inpatient care: What factors explain which hospitals receive innovation payments?

Ex, Patricia ; Vogt, Verena ; Busse, Reinhard ; Henschke, Cornelia (2019-06-04)

Most hospital payment systems based on diagnosis-related groups (DRGs) provide payments for newly approved technologies. In Germany, they are negotiated between individual hospitals and health insurances. The aim of our study is to assess the functioning of temporary reimbursement mechanisms. We used multilevel logistic regression to examine factors at the hospital and state levels that are ass...

Changing payment instruments and the utilisation of new medical technologies

Ex, Patricia ; Henschke, Cornelia (2019-05-29)

This paper empirically investigates the impact of additional reimbursement instruments on the diffusion of new technologies in inpatient care. Using 2010–2014 German panel data on hospital level for every patient undergoing coronary angioplasty, this study examines the utilisation of drug-eluting balloon catheters (DEB) over time while additional payment instruments changed. Hypothesising that ...

Successful corporate sustainability management in energy companies and beyond: a systems perspective

Priemer, Stefanie (2019)

This dissertation aims at enhancing our understanding of how companies may successfully manage their engagement in sustainability. In research, successfully managed corporate sustainability (CS) is widely argued to lead to implemented CS in a company and increased CS-related performance. However, practitioners lack guidance on what to address along the environmental, social, and economic CS dim...

Achieving Sustainability and Scale-Up of Mobile Health Noncommunicable Disease Interventions in Sub-Saharan Africa: Views of Policy Makers in Ghana

Opoku, Daniel ; Busse, Reinhard ; Quentin, Wilm (2019-05-03)

Background: A growing body of evidence shows that mobile health (mHealth) interventions may improve treatment and care for the rapidly rising number of patients with noncommunicable diseases (NCDs) in sub-Saharan Africa (SSA). A recent realist review developed a framework highlighting the influence of context factors, including predisposing characteristics, needs, and enabling resources (PNE), ...

Medikamentöse Behandlung von Heimbewohnern mit Schlafstörungen

Kuck, Joachim (2019)

Obwohl Schlafstörungen unter Heimbewohnern weit verbreitet sind, wurden sie bisher von den Gesundheitswissenschaften als Problem kaum wahrgenommen. Wegen ihres hohen Alters sind Heimbewohner häufig von körperlichen oder psychiatrischen Erkrankungen betroffen, die zu Schlafstörungen führen können. In der Folge leiden Heimbewohner mit Schlafproblemen unter Müdigkeit, eingeschränkter Leistungsfähi...

Open Innovation in der Logistik – Entwicklung eines Gestaltungsmodells zum Aufbau eines offenen Innovationsmanagements in logistischen Dienstleistungsuntermnehmen

Reipert, Jan (2019)

In einer zunehmend von Globalisierung und steigender Arbeitsteilung geprägten Welt gewinnt die Effizienz von Wertschöpfungs- und Logistikketten stetig an Bedeutung. Um sich auf ihre Kernkompetenzen konzentrieren zu können, vergeben Industrie und Handel die dafür notwendigen Leistungen zu großen Teilen fremd. Der hohe Konkurrenzdruck im Markt führt dazu, dass der Wettbewerb oftmals über den Prei...
