PurposeFocal cartilage defects in the knee may have devastating effect on the knee joint, where two of the main surgical treatment options are microfracture and autologous chondrocyte implantation. Comparative studies have failed to establish which method yields the best clinical results. A cost-effectiveness analysis of microfracture and autologous chondrocyte implantation would contribute to the clinical decision process.MethodsA PubMed search identifying level I and level II studies with 5 year follow-up was performed. With the data from these studies, decision trees with associated service provision and costs connected to the two different techniques were designed. In addition to hospital costs, we included costs connected to physiotherapy following surgery. To paint a broader cost picture, we also included indirect costs to the society due to productivity loss caused by work absence.ResultsFour high-quality studies, with a follow-up of 5 years, met the inclusion criteria. A total of 319 patients were included, 170 undergoing microfracture and 149 autologous chondrocyte implantation. The re-operation rate was 23 (13.5%) following microfracture, and 18 (12.1%) for autologous chondrocyte implantation. Both groups achieved substantially better clinical scores at 5 years compared to baseline. Microfracture was more cost-effective when comparing all clinical scores.ConclusionMicrofracture is associated with both lower costs and lower cost per point increase in patient reported outcome measures. There is a need of well-designed, high-quality randomized controlled trials before reliable conclusions regarding cost-effectiveness in the long run is possible.Level of evidenceIII.

Paid sick leaves for caregivers that are employed, and hospital-at-home programmes that provide education and surveillance to the patient and his/her family through different phases of the illness, are policy means that both can help the informal caregivers to manage daily life and reduce the pressure on the formal healthcare and long-term care services in the future.

In the Norwegian capitation trial, the payment system for general practitioners (GPs) has been changed; a practice allowance component has been replaced by a capitation component and the fee-per-item component constitutes a smaller part of a GPs practice income than previously. From the theoretical modelling of GPs' referral decisions, we predict that the replacement of the practice allowance by a capitation component will increase the rate of referrals to specialists. This hypothesis is supported by an exploratory empirical study with data from a sample of GPs participating in the experiment.
