Effectiveness Analysis

Objective.To evaluate the cost-effectiveness of 3 alternative active screening strategies for methicillin-resistant Staphylococcus aureus (MRSA): universal surveillance screening for all hospital admissions, targeted surveillance screening for intensive care unit admissions, and no surveillance screening.Design.Cost-effectiveness analysis using decision modeling.Methods.Cost-effectiveness was evaluated from the perspective of an 800-bed academic hospital with 40,000 annual admissions over the time horizon of a hospitalization. All input probabilities, costs, and outcome data were obtained through a comprehensive literature review. Effectiveness outcome was MRSA healthcare-associated infections (HAIs). One-way and probabilistic sensitivity analyses were conducted.Results.In the base case, targeted surveillance screening was a dominant strategy (ie, was associated with lower costs and resulted in better outcomes) for preventing MRSA HAL Universal surveillance screening was associated with an incremental cost-effectiveness ratio of $14,955 per MRSA HAL In one-way sensitivity analysis, targeted surveillance screening was a dominant strategy across most parameter ranges. Probabilistic sensitivity analysis also demonstrated that targeted surveillance screening was the most cost-effective strategy when willingness to pay to prevent a case of MRSA HAI was less than $71,300.Conclusion.Targeted active surveillance screening for MRSA is the most cost-effective screening strategy in an academic hospital setting. Additional studies that are based on actual hospital data are needed to validate this model. However, the model supports current recommendations to use active surveillance to detect MRSA.

The Impact

Background: Studies on cost effectiveness analysis (CEA) of typical versus atypical antipsychotics in the management of schizophrenia are still lacking in Nigeria thus the objectives of this study are to determine which of the class of antipsychotics is more cost-effective as well as the impact of socio-demographic factors on the response rate to antipsychotics. Method: The effectiveness was measured by Brief Psychiatric rating scale (BPRS) and costs were in Nigerian naira (NGN). The impact of different socio-demographics on the mean BPRScore ± Standard deviation (SD) reduction was determined. The study was conducted from patient’s perspective with decision tree analysis model using two-way sensitivity analysis. The model was used to explore incremental cost effectiveness ratios (ICER) of oral antipsychotic medications Haloperidol /Trifluoperazine versus Olanzepine /Risperidone over a 24-week study period. Results: Cost effectiveness analysis with 1st scenario sensitivity test of medications, trifluoperazine 17.81±2.51mg is more cost effective than olanzapine 10mg, while haloperidol 10mg is more cost effective than risperidone 3.5± 0.51mg. In the second scenario of sensitivity analysis, olanzapine is more cost effective than trifluoperazine only when the savings of making one person free from schizophrenia in a month is worth more than NGN537 while risperidone is more cost effective than haloperidol only when the savings of making one person free from schizophrenia in a month is worth more than NGN2524.1. The effect on response rate to antipsychotics gave p=0.0251, P=0.009, P<0.0001 for educational status, income, stable relationship respectively. Conclusion: Atypical antipsychotic medications are not more cost effective compared to the typical antipsychotics. Higher educational level, income and stable relationship positively affected the outcome of effectiveness of antipsychotics.

Standard surgical antimicrobial prophylaxis (SAP) regimens are less effective in preventing surgical site infections (SSIs) due to rising antimicrobial resistance (AMR) rates, particularly for patients undergoing colorectal surgery. This study aimed to evaluate whether ertapenem should be a preferred strategy for the prevention of SSIs following elective colorectal surgery compared to three standard SAP regimens: amoxicillin-clavulanate, cefoxitin, and cefazolin plus metronidazole. A cost-effectiveness analysis was conducted using decision tree models. Probabilities of SSIs and AMR-SSIs, costs, and effects (in terms of quality-adjusted life-years) were considered in the assessment of the alternative strategies. Input parameters integrated real data from the Italian surveillance system for SSIs with data from the published literature. A sensitivity analysis was conducted to assess the potential impact of the decreasing efficacy of standard SAP regimens in preventing SSIs. According to our models, ertapenem was the most cost-effective strategy only when compared to amoxicillin-clavulanate, but it did not prove to be superior to cefoxitin and cefazolin plus metronidazole. The sensitivity analysis found ertapenem would be the most cost-effective strategy compared to these agents if their failure rate was more than doubled. The findings of this study suggest ertapenem should not be a preferred strategy for SAP in elective colorectal surgery.
