Patient-controlled analgesia (PCA) is the use of a portable infusion pump activated by the patient to inject an analgesic drug intravenously, subcutaneously or epidurally. PCA permits a patient to deliver a small bolus of opioid to achieve prompt relief without over sedation. Use of PCA for pain management is increasing in hospitals and home settings, largely because it can provide equivalent or better analgesia than conventional methods, and patients are more satisfied with its use. ⋯ Also, researchers do not include the full scope of costs associated with the use of PCA in comparison with conventional drug delivery methods and some do not measure the level of pain relief achieved. Of the few complete and well designed published studies found, PCA was reported to produce superior analgesia at a higher cost than conventional intramuscular therapy in 3 studies, but to be more costly and produce less pain relief than intramuscular therapy in 1 study. There is a pressing need for cost-effectiveness, cost-utility and cost-benefit analyses to determine the appropriate clinical and cost circumstances for the use of PCA.

Clinical Trial
Pharmacoeconomic analysis of venlafaxine in the treatment of major depressive disorder.
We conducted a cost-effectiveness analysis of acute major depressive disorder (MDD) using serotonin-norepinephrine reuptake inhibitors (SNRIs; venlafaxine), selective serotonin reuptake inhibitors (SSRIs; fluoxetine, fluvoxamine, sertraline, paroxetine), or tricyclic antidepressants (TCAs; amitriptyline, imipramine, desipramine, nortriptyline). A decision-tree model over 6 months was constructed using an expert panel. The analytic perspective was that of the Ontario Ministry of Health as payor for all direct costs, which were derived from standard lists and included the cost of the drug as well as those for medical care, laboratory services, hospitalisation and managing adverse events. ⋯ Venlafaxine was dominant for all incremental pharmacoeconomic analyses. Sensitivity analyses indicated that the results were robust for outpatients but somewhat sensitive for inpatients. In conclusion, venlafaxine is a cost-effective drug for the treatment of MDD in adult outpatients and inpatients.

A prospective economic analysis of autologous peripheral blood progenitor-cell transplantation (PBPCT) versus autologous bone marrow transplantation (BMT) was performed as part of a randomised clinical trial in 129 patient (adults and children) receiving high-dosage antineoplastic therapy for non-leukaemic malignant disease. The clinical assessment criteria of the study were the duration of thrombocytopenia (< 30 x 10(9)/L and < 50 x 10(9)/L) and of granulocytopenia (< 0.5 x 10(9)/L). The cost of medical resources used was the primary economic end-point. ⋯ The global costs of PBPCT were lower than those of BMT for these adult and paediatric populations. Economic arguments can clearly be added to clinical ones in favour of substitution of autologous PBPCT for autologous BMT. International comparisons of diffusion of PBPCT could be of great interest for further economic research into medical innovation.

Comparative Study
Full-cost determination of different levels of care in the intensive care unit. An activity-based costing approach.
We applied an activity-based costing methodology to determine the full cost of intensive care service at a community hospital, a university hospital and a health maintenance organisation (HMO)-affiliated hospital. A total of 5 patient care units were analysed: the intensive care unit (ICU) and surgical ICU (SICU) at the university setting, the ICU at the community setting, and the SICU and cardiac care unit at the HMO setting. ⋯ The analysis revealed a marked increase in patient-minute cost associated with mechanical ventilation. Higher costs associated with prolonged neuromuscular blockade have important economic implications with respect to selection of an appropriate neuromuscular blocking agent.

Comparative Study
Enoxaparin. A pharmacoeconomic appraisal of its use in thromboembolic prophylaxis after total hip arthroplasty.
Total hip arthroplasty (THA) is a major orthopaedic procedure with a high risk of postoperative thromboembolism. Increasing demand for this type of surgery, together with its high cost, has led to examination of means by which the cost of THA may be minimised. Current clinical opinion favours the use of suitable pharmacological thromboprophylaxis in patients undergoing THA; such prophylaxis may be provided with subcutaneous standard unfractionated heparin (UFH), oral warfarin or subcutaneous low molecular weight heparin (LMWH). ⋯ It has also been suggested that the use of once- or twice-daily enoxaparin in preference to UFH may reduce the overall length of hospital stay; a significant difference emerged in 1 analysis (9.9 or 9.5 vs 11.3 days). Pharmacoeconomic data therefore support the use of enoxaparin as an effective thromboprophylactic treatment with potential cost advantages over warfarin and UFH. Cost-effecti
