Cost-effectiveness of Oral Versus Intravenous Ibuprofen Therapy in Preterm Infants With Patent Ductus Arteriosus in the Neonatal Intensive Care Setting: A Cohort-based Study

A cost-effectiveness analysis for high versus standard (low) dose caffeine for the treatment of apnea in neonatal intensive care unit

Objective

Preterm babies are prone to experiencing apnea of prematurity (AOP), mostly characterised by a pause in breathing lasting a minimum of 20 seconds. Recent literature supported higher maintenance doses of caffeine, indicating benefits. This study evaluated the cost-effectiveness of high maintenance dose (HD) versus low maintenance dose (LD) caffeine for AOP in neonates.

Methods

From the hospital perspective of Hamad Medical Corporation (HMC), Qatar, a cost-effectiveness decision-analytic model was constructed to follow the use of a HD maintenance caffeine of 20 mg/kg/dose versus a LD maintenance caffeine of 10 mg/kg/dose, in a simulated cohort of AOP neonates, over a therapy follow-up duration of six weeks, until neonatal intensive care (NICU) discharge. The clinical inputs were primarily literature-based, while the resource cost and utilisation were locally extracted in HMC. The cost-effectiveness outcome measure was calculated per therapy success, defined as survival with no apnea and successful extubation removal within 72 hours, with or without adverse events. One-way and multivariate sensitivity analyses were performed to confirm the robustness of the results.

Results

With 0.23 (95% CI, 0.23-0.23) enhancement in success rate, at United States dollar (US$) 3869 (95% CI, US$ 3823-3915) added infant cost, the HD caffeine was between dominant (34.8%) and cost-effective (63.7%), with an average incremental cost-effectiveness ratio of US $16,895 (95% CI, US$ 15,242-18,549) relative to LD caffeine per additional case of success. The hospitalisation contributed the most to the total infant cost, and the probability of patent ductus arteriosus was the model input that influenced the results most.

Conclusion

This is the first literature economic evaluation of caffeine for AOP. Despite increasing the cost of therapy, HD maintenance caffeine seems to be a cost-effective alternative to LD caffeine in Qatar. Our results support the recent global trends of increased use of HD caffeine for AOP in NICU.

The impact of the route of administration on the efficacy and safety of the drug therapy for patent ductus arteriosus in premature infants: a systematic review and meta-analysis

Background

This systematic review and meta-analysis aims to explore the potential impact of the route of administration on the efficacy of therapies and occurrence of adverse events when administering medications to premature infants with patent ductus arteriosus (PDA).

Method

The protocol for this review has been registered with PROSPERO (CRD 42022324598). We searched relevant studies in PubMed, Embase, Cochrane, and the Web of Science databases from March 26, 1996, to January 31, 2022.

Results

A total of six randomized controlled trials (RCTs) and five observational studies were included for analysis, involving 630 premature neonates in total. Among these infants, 480 were in the ibuprofen group (oral vs. intravenous routes), 78 in the paracetamol group (oral vs. intravenous routes), and 72 in the ibuprofen group (rectal vs. oral routes). Our meta-analysis revealed a significant difference in the rate of PDA closure between the the initial course of oral ibuprofen and intravenous ibuprofen groups (relative risk (RR) = 1.27, 95% confidence interval (CI) [1.13-1.44]; P < 0.0001, I2 = 0%). In contrast, the meta-analysis of paracetamol administration via oral versus intravenous routes showed no significant difference in PDA closure rates (RR = 0.86, 95% CI [0.38-1.91]; P = 0.71, I2 = 76%). However, there was no statistically significant difference in the risk of adverse events or the need for surgical intervention among various drug administration methods after the complete course of drug therapy.

Conclusion

This meta-analysis evaluated the safety and effectiveness of different medication routes for treating PDA in premature infants. Our analysis results revealed that compared with intravenous administration, oral ibuprofen may offer certain advantages in closing PDA without increasing the risk of adverse events. Conversely, the use of paracetamol demonstrated no significant difference in PDA closure and the risk of adverse events between oral and intravenous administration.

Clinical pharmacists' interventions for preventing adverse events in critically ill neonates in Qatar: an economic impact analysis

Objective

This study aimed to assess the overall economic impact of clinical pharmacist interventions in the neonatal ICU (NICU) in Qatar.

Methods

A retrospective review of neonates' records was performed over a 3-month duration in the NICU of Qatar to determine the total economic benefit of clinical pharmacist interventions. The total benefit of interventions was calculated by considering the cost avoidance due to preventable adverse drug events (ADEs) and the cost savings associated with the revised resource use due to interventions. Sensitivity analyses were conducted to ensure the robustness and generalizability of the results.

Results

A total of 513 interventions were analyzed, involving 150 neonates. Most of the drug-related problems were related to therapy dosing, followed by drug choice appropriateness, the addition of prophylactic treatment, and administration frequency. The overall annual benefit was estimated at QAR 4,178,352 (1,147,584), which consisted of cost avoidance of QAR 1,050,680 (USD 288,648) and an overall cost saving of QAR -6091 (USD -1673).

Conclusions

While the clinical pharmacist interventions led to increased resource utilisation and associated costs, when considering the avoided costs of ADEs, the overall clinical pharmacist practices in the NICU setting were economically beneficial.

Cost‑effectiveness of add‑on dapagliflozin for heart failure with reduced ejection fraction patients without diabetes

AIM

To evaluate the cost-effectiveness of dapagliflozin added to standard of care (SoC) versus SoC in heart failure with reduced ejection fraction (HFrEF) and without type 2 diabetes mellitus (T2DM) patients from the Qatari healthcare perspective.

MATERIALS AND METHODS

A lifetime Markov model was developed to evaluate the cost-effectiveness of adding dapagliflozin to SoC based on the findings of Petrie et al. 2020, which were based on the DAPA-HF trial. The model was constructed based on four health states: "alive with no event", "urgent visit for heart failure", "hospitalization for heart failure", and "dead". The model considered 1,000 hypothetical HFrEF and without T2DM patients using 3-month cycles over a lifetime horizon. The outcome of interest was the incremental cost-effectiveness ratio (ICER) per quality-adjusted life-year gained (QALY) and years of life lived (YLL). Utility and cost data were obtained from published sources. A scenario analysis was performed to replace the transition probabilities of events in people without T2DM with the transition probabilities of events irrespective of T2DM status, based on findings of the DAPA-HF trial. Sensitivity analyses were conducted to confirm the robustness of the conclusion.

RESULTS

Adding dapagliflozin to SoC was estimated to dominate SoC alone, resulting in 0.6 QALY and 0.8 YLL, at a cost saving of QAR771 (USD211) per person compared with SoC alone, with total healthcare costs of QAR42,413 (USD 11,620) versus 43,184 (USD11,831) per person, respectively. When replacing the transition probabilities of events in people without T2DM with the transition probabilities of events in people irrespective of T2DM status, dapagliflozin was cost-effective at ICER of QAR5,212 (USD1,428) per QALY gained and QAR3,880 (USD1,063) per YLL. In the probabilistic sensitivity analysis, dapagliflozin combined with SoC was cost saving in over 49% of the cases and cost-effective in over 43% of the simulated cases against QALYs gained and YLL.

LIMITATIONS

Data from clinical trials were used instead of local data, which may limit the local relevance. However, evidence from the local Qatari population is lacking. Also, indirect costs were not included due to a paucity of available data.

CONCLUSIONS

Adding dapagliflozin to SoC is likely to be a cost-saving therapy for patients with HFrEF and without T2DM in Qatar.

Cost savings and cost avoidance with the inpatient clinical pharmacist interventions in a tertiary cancer care hospital

BACKGROUND

The economic benefit of the clinical pharmacist's role in ensuring the optimum use of medicines is potentially considerable, particularly when it comes to cancer management. We sought to evaluate the overall economic impact of clinical pharmacist interventions in the main cancer setting in Qatar.

METHODS

The total economic benefit of the clinical pharmacy interventions were analyzed from the public hospital perspective. Patient records in March 2018, July/August 2018, and January 2019 were retrospectively reviewed at the National Center for Cancer Care and Research, Qatar. The total benefit from interventions was the total cost avoidance due to preventable adverse drug events plus any cost savings associated with therapeutic-based resource use. Sensitivity analyses confirmed the results' robustness and increased generalizability.

RESULTS

A total of 1352 interventions based on 281 patients were analyzed. The majority of the drug-related problems were related to the appropriateness of therapy, followed by dosing and administration. The total population benefit over the 3-months study period was QAR 4,879,185 (USD 1,336,763), constituting cost avoidance of QAR 4,234,012 (USD 1,160,003) and negative resource-use cost savings of -QAR 645,174 (-USD 176,760). Projected annual overall benefit was QAR 14,355,354 (USD 3,932,974). The increase in resource use with therapies was mostly because of the addition of other medications. Cost avoidance was mostly driven by recommending additional medications and discontinuation of medications. The uncertainty analysis demonstrated the robustness of outcomes.

CONCLUSIONS

The clinical pharmacist intervention increased resource use and its cost. In overall, however, taking avoided cost of adverse drug events in consideration, it is an economically beneficial practice in the National Center for Cancer Care and Research setting, associated with adverse drug events prevention and substantial economic benefits.

Cost-effectiveness Analysis of Ibuprofen versus Indomethacin or Paracetamol for the Treatment of Patent Ductus Arteriosus in Preterm Neonates

OBJECTIVE

This was a first-time evaluation that sought to analyze the cost-effectiveness of oral paracetamol and intravenous (IV) indomethacin as alternatives to ibuprofen for PDA in neonates.

METHODS

Decision-analytic, literature-based, economic simulation models were constructed, to follow up the use and consequences of oral/IV ibuprofen versus IV indomethacin, and oral/IV ibuprofen versus oral paracetamol, as first-line therapies for PDA closure. Model outcomes of interest were 'success', defined as PDA closure with/without adverse events, or 'failure' due to no response to the first course of treatment, death or premature discontinuation of therapy due to AEs.

RESULTS

Oral ibuprofen is dominant/cost-effective over IV indomethacin in 97.9% of simulated cases, but oral paracetamol was 75.2% dominant/cost-effective over oral ibuprofen. Against IV ibuprofen, IV indomethacin was 55.3% dominant/cost-effective, whereas oral paracetamol was dominant/cost-effective in 98.5% of the cases. Sensitivity analyses confirmed the robustness of the study results.

CONCLUSION

For PDA closure, while IV indomethacin was cost-effective against IV ibuprofen, oral paracetamol was cost-effective against both oral and IV ibuprofen.

Cost-Effectiveness Analysis of Out-Of-Hospital versus In-Hospital Extracorporeal Cardiopulmonary Resuscitation for Out-Hospital Refractory Cardiac Arrest

It has been speculated that out-of-hospital cardiac arrest (OHCA) patients' survival might be improved by implementing extracorporeal cardiopulmonary resuscitation (ECPR) before arrival to hospital. Therefore, we sought to assess the cost-effectiveness of OH-ECPR versus in-hospital (IH)-ECPR in OHCA patients in Qatar. From the hospital perspective, a conventional decision-analytic model was constructed to follow up the clinical and economic consequences of OH-ECPR versus IH-ECPR in a simulated OHCA population over one year. The primary outcome was the survival at discharge after arrest as well as the overall direct healthcare costs of managing OHCA patients. The robustness of this model was evaluated via sensitivity analyses. The OH-ECPR yielded 16% survival at discharge after arrest compared to 7% with IH-ECPR, [risk ratio (RR)=0.91; 95%CI 0.79 to 1.06; P=0.26]. Incorporating the uncertainty associated with this survival rate, and based on the estimated willingness to pay threshold in Qatar, the OH-ECPR was cost-effective with an incremental cost-effectiveness ratio of QAR 464,589 (USD 127,634). Sensitivity and uncertainty analyses confirmed the robustness of the study outcome. This is the first cost-effectiveness evaluation of OH-ECPR versus IH-ECPR in OHCA patients. OH-ECPR is potentially an economically acceptable resuscitative strategy in Qatar.

Quantifying the Value of Introducing an Oral Drug Delivery Option for Edaravone: A Review of Analyses Evaluating the Economic Impact of Oral versus Intravenous Formulations

Background

Drug formulation and route of administration can have an impact on not only patients’ quality of life and disease outcomes but also costs of care. It is essential for decision makers to use appropriate economic modeling methods to guide drug coverage policies and to support patients’ decision-making.

Purpose

To illustrate key cost considerations for decision makers in economic evaluation of innovative oral formulations as alternatives to intravenous medication.

Materials and Methods

A structured literature review was conducted using the PubMed database to examine methods used for quantifying the economic impact of introducing a new oral pharmaceutical formulation as an alternative to intravenous medication. To illustrate the methods described in this review, a cost-minimization analysis was conducted to quantify the impact of introducing an oral formulation of a medication originally developed as an intravenous treatment for amyotrophic lateral sclerosis.

Results

We identified 14 published evaluations of oral and intravenous formulations from 10 countries across a variety of disease areas. The identified studies used cost-effectiveness (n=10), cost-minimization (n=2), and cost-calculation (n=2) modeling approaches. All but one (13/14) reported outcomes from payers’ perspective, while societal perspectives were also incorporated in 3 of the reviewed evaluations. One study estimated costs from a public hospital’s perspective. Only a subset of the identified studies accounted for the effects of safety (n=6) or efficacy (n=8) differences on treatment costs when estimating the costs of a formulation choice. Many studies that omitted these aspects did not include rationales for their decisions.

Conclusion

We found significant design variations in published models that estimated the impact of an additional formulation option on the treatment costs to payers and the society. Models need to be accompanied with clear descriptions on rationales for their time horizons and assumptions on how different formulations may affect healthcare costs from the selected perspectives.
