Cost savings of outpatient parenteral antimicrobial therapy using a digital infusion pump. JAC-Antimicrobial Resistance (JAC-AMR). 8(3). doi: 10.1093/jacamr/dlag052.

  Background and objectives: Outpatient parenteral antimicrobial therapy (OPAT) enables IV antibiotic adminis-tration outside hospital settings and has been found to reduce costs and improve patient satisfaction. In Norway, OPAT has been less established due to the preference for narrow-spectrum antibiotics often requiring multiple daily doses. We undertook a cost evaluation of an OPAT programme using a continuous ambulatory de-livery device (CADD), and comparison with costs of inpatient treatment for equivalent IV antibiotic courses. Materials and methods: A retrospective cost analysis was conducted on 170 consecutive patients treated with OPAT at Sørlandet Hospital, Norway (2016–2021). Eligible patients received multidose IV antibiotics at home using CADD pumps. OPAT costs included equipment and antibiotics, staff time, transportation and patient time, and were compared with estimated inpatient costs for the same treatment and duration. Sensitivity ana-lyses tested robustness of the findings across various cost scenarios. Results: A total of 170 patients received OPAT, mostly with narrow-spectrum β-lactam antibiotics, with a mean duration of 16.4 days per patient (range 1–67 days), and an estimated saving of approximately 51 hospital bed days per month. The mean cost per OPAT treatment was €1603 versus €12 982 for inpatient care, i.e. represent-ing 12% of inpatient costs. Sensitivity analysis confirmed OPAT savings between 72% and 89% across scenarios. Conclusions: These findings confirm that a CADD-based OPAT programme considerably reduces costs on a so-cietal perspective in a publicly funded health system and contributes to reduced hospital bed occupancy. The ability to administer narrow-spectrum antibiotics supports antimicrobial stewardship.

  Boligprisene i Norge har over lang tid økt. Samtidig har boligprisutviklingen i noen regioner avveket fra trendveksten for landet som helhet, både på kort og lang sikt. Mens boligprisene i Oslo har økt mest i årene etter 2010, var veksten i boligpriser i perioden 2005-2008 vesentlig sterkere både i Kristiansand og Stavanger, i Stavanger også i årene fram til 2014. Vi drøfter ulike årsaker til den observerte veksten i boligpriser og de regionale forskjellene. Store svingninger i boligpriser kan potensielt ha store samfunnsøkonomiske konsekvenser og vi diskuterer aktuelle regulatoriske tiltak

  A questionnaire-type experiment was conducted in Lithuania and Norway in order to generate two samples suitable for a comparative examiniation of equity judgements. The results reveal large differences between the two countries. Norwegian probants had a much higher propensity to decide in accordance with Rawls's second principle than had Lituanian probants. Equity judgements are also strongly dependent on the context of choice. The results are interpreted withing a framework describing the formaton of social preferences. More specifically, differences in observed equity judgements in the two countries are related to differences in history, experience and future prospects.

  A theoretical model is developed explaining formal sector workers participation in the informal sector. A reduced-form informal sector participation function is derived from a specific utility function, a specific informal sector production function and a specific informal sector earnings function. The participation function can be estimated consistently, and provides a solution to the problem that informal sector “wages” in developing countries are hard to observe. A sample of Tanzanian formal sector workers is used to estimate the participation function. A majority of Tanzanian formal sector workers participate in informal production. Participation in informal production is inversely related to household income, to living in Dar es Salaam, and to being a mother with small children. Participation is positively related to age, and multiple-job-holding seems to play a very different role in the transition from work to retirement in Tanzania compared to industrialised countries.

  We set up a theoretical model for how a long-term care-user responds to changes in rationed long-term care-services. Similarly, we model the rationing of service-provision by a public sector bureau. The interaction between the bureau and care-recipients is modeled as a non-cooperative game. We establish that a Nash-equilibrium exists, and argue that ample provision of long-term care-services may lead to a degradation of care-recipients productivity in self-care. This theoretical result is supported by empirical evidence: High-income municipalities have a disproportionately higher share of frail individuals, even when differences in age-structure, death-rates, etc., are controlled for.

  In a sample of Tanzanian formal sector workers we find that the vast majority have a desire for working longer hours in their main job, and supplement earnings through participation in informal production. Determinants of participation in informal production are examined through estimation of a structural-form Logit model. The results show that participation in informal production is inversely related to income, and positively related to age. Age seems to play a very different role in the transition from work to retirement in Tanzania compared to industrialised countries.

• Theisen, Theis (2005). Formal sector workers' participation in informal production: A reduced form approach based on Tanzanian data. Fulltekst i vitenarkiv Vis sammendrag

  We develop a theoretical model explaining formal sector workers participation in the informal sector. From a specific utility function, a specific informal sector production function and a specific informal sector earnings function we derive a reduced form informal sector participation function. The conditions under which the reduced form participation function can be consistently estimated are strict, but provide a solution to the problem that informal sector “wages” in developing countries are hard to observe. A sample of Tanzanian formal sector workers is used to estimate the participation function. A majority of the individuals in the sample are multiple-job-holders participating in as well formal as informal production. Formal sector workers’ participation in informal production is inversely related to household income, to living in Dar es Salaam, and to being a mother with small children. Participation is positively related to age, and multiple-job-holding seems to play a very different role in the transition from work to retirement in Tanzania compared to industrialised countries.
