The OMBU model lends itself to greater cost-effectiveness due to economies of scale, with large number of women using the facility.
This non-invasive technique, which is standardly available in pre-surgically staged lung cancer patients, may increase cost-effectiveness due to less cumbersome diagnostic procedures and more efficient identification of potentially curable second primary cancer patients.
Estimates of the mean error in the mean time (mean absolute error) are displayed because this indicates the approximate expected error in resulting estimates of cost-effectiveness due to uncertainty in the survival distribution.
Further, while we assumed that all children covered would receive a full 3 doses of vaccine, in practice dose completion rates may vary, affecting the total cost and altering cost-effectiveness (due to both changes in cost and changes in impact if vaccine efficacy with fewer than 3 doses is lower than that under a full 3-dose course).
Although several authors aimed to compare surgical with conservative treatment [ 2- 22], these reports are difficult to use for cost effectiveness analysis due to lack of necessary information and use of outdated surgical techniques.
17 Uncertainty in the estimated incremental cost effectiveness ratios due to sampling uncertainty in the estimated input parameter values was evaluated by employing probabilistic sensitivity analysis in which simulation was used to propagate uncertainty in individual model inputs through the model in order to assess the uncertainty in the outcome of interest, incremental cost effectiveness.
We can apply the bootstrap to the model defined by equation (1) whilst allowing both for the relationship between the cost and the effectiveness and for the non-independence of the cost and the effectiveness due to clustering of the data.
Two large pragmatic cluster randomised trials [ 6, 7] with ambulatory primary care clinics as the unit of randomisation demonstrated clear impact improvements and acceptable cost effectiveness [ 8] due to a different in-service training approach (on-site, face-to-face team training by an outreach trainer), compared with usual off-site training.
Current treatments suffer of high toxicity for the patient, low efficacy toward the parasite, high cost, and are losing effectiveness due to parasite resistance.
It was recognised that cost effectiveness requires considered analysis due to its complexity which needs to take into consideration patient satisfaction and quality of service provided.
At the lower prevalence estimate (10%), cost effectiveness values significantly increased due to screening preventing less downstream cases of active TB (this is logical as, in extremis, screening a population with no infection is completely ineffective).
