Principles of pharmacoeconomic analysis: the case of pharmacist-led interventions

Clinical pharmacy key performance indicators for hospital inpatient setting: a systematic review

BACKGROUND

Key performance indicators (KPIs) are quantifiable measures used to monitor the quality of health services. Implementation guidelines for clinical pharmacy services (CPS) do not specify KPIs.

AIM

To assess the quality of the studies that have developed KPIs for CPS in inpatient hospital settings.

METHOD

A systematic review was conducted by searching in Web of Science, Scopus, and PubMed, supplemented with citation analyses and grey literature searches, to retrieve studies addressing the development of KPIs in CPS for hospital inpatients. Exclusions comprised drug- or disease-specific studies and those not written in English, French, Portuguese, or Spanish. The Appraisal of Indicators through Research and Evaluation (AIRE) instrument assessed methodological quality. Domain scores and an overall score were calculated using an equal-weight principle. KPIs were classified into structure, process, and outcome categories. The protocol is available at https://doi.org/10.17605/OSF.IO/KS2G3 .

RESULTS

We included thirteen studies that collectively developed 225 KPIs. Merely five studies scored over 50% on the AIRE instrument, with domains #3 (scientific evidence) and #4 (formulation and usage) displaying low scores. Among the KPIs, 8.4% were classified as structure, 85.8% as process, and 5.8% as outcome indicators. The overall methodological quality did not exhibit a clear association with a major focus on outcomes. None of the studies provided benchmarking reference values.

CONCLUSION

The KPIs formulated for evaluating CPS in hospital settings primarily comprised process measures, predominantly suggested by pharmacists, with inadequate evidence support, lacked piloting or validation, and consequently, were devoid of benchmarking reference values.

Revolutionizing Cancer Treatment: The Promising Horizon of Zein Nanosystems

Various nanomaterials have recently become fascinating tools in cancer diagnostic applications because of their multifunctional and inherent molecular characteristics that support efficient diagnosis and image-guided therapy. Zein nanoparticles are a protein derived from maize. It belongs to the class of prolamins possessing a spherical structure with conformational properties similar to those of conventional globular proteins like ribonuclease and insulin. Zein nanoparticles have gained massive interest over the past couple of years owing to their natural hydrophilicity, ease of functionalization, biodegradability, and biocompatibility, thereby improving oral bioavailability, nanoparticle targeting, and prolonged drug administration. Thus, zein nanoparticles are becoming a promising candidate for precision cancer drug delivery. This review highlights the clinical significance of applying zein nanosystems for cancer theragnostic─moreover, the role of zein nanosystems for cancer drug delivery, anticancer agents, and gene therapy. Finally, the difficulties and potential uses of these NPs in cancer treatment and detection are discussed. This review will pave the way for researchers to develop theranostic strategies for precision medicine utilizing zein nanosystems.

The Cost-Effectiveness of Dolutegravir in Combination with Tenofovir and Lamivudine for HIV Therapy: A Systematic Review

The World Health Organization (WHO) recommends dolutegravir (DTG), a human immunodeficiency virus (HIV) medicine, as the first- and second-line treatment for all populations because, when compared to an efavirenz (EFV) regimen, plus two nucleoside reverse transcriptase inhibitors (NRTIs) has demonstrated significant effectiveness in HIV suppression in persons. This study aims to review evidence of the cost-effectiveness of DTG in combination with tenofovir and lamivudine compared with the standard of care for HIV therapy. The systematic review involved searching electronic databases for articles published between January 2018 and May 2022. Electronic database sources include PubMed, ScienceDirect, and EBSCO for articles on DTG in combination with tenofovir and lamivudine as subjects with cost-effectiveness outcomes. The inclusion criteria in this systematic review were studies about the cost-effectiveness analysis (CEA) of DTG in combination with tenofovir and lamivudine, written in English. A total of 145 articles were identified from three databases. After removing nine duplicates, 142 articles were screened by title and abstract, excluding 123 articles. After a full-text screening of 19 articles, five articles were selected for further analysis. Five articles reviewed in sub-Saharan Africa, India, and China implemented different modelling methods for CEA but produced similar results. The results of these studies demonstrate that it is more cost-effective than standard care for HIV treatment. The study conducted in sub-Saharan Africa from 2018 to 2020 showed a cost-effective result with disability-adjusted life years averted (DALY averted) by 83%; in India, it resulted in incremental cost-effectiveness ratio (ICER) $130 per year of live-saved (YLS); and a study in China found that dolutegravir plus tenofovir and lamivudine led to 0.006 incremental quality-adjusted life years (QALYs) with cost savings of $64. The DTG regimen is cost-effective and recommended for HIV therapy in all studies that provide results.

Polypharmacy in chronic kidney disease: Health outcomes & pharmacy-based strategies to mitigate inappropriate polypharmacy

The rising prevalence of comorbidities in an increasingly aging population has sparked a reciprocal rise in polypharmacy. Patients with chronic kidney disease (CKD) have a greater burden of polypharmacy due to the comorbidities and complications associated with their disease. Polypharmacy in CKD patients has been linked to myriad direct and indirect costs for patients and the society at large. Pharmacists are uniquely positioned within the healthcare team to streamline polypharmacy management in the setting of CKD. In this article, we review the landscape of polypharmacy and examine its impacts through the lens of the ECHO model of Economic, Clinical, and Humanistic Outcomes. We also present strategies for healthcare teams to improve polypharmacy care through comprehensive medication management process that includes medication reconciliation during transitions of care, medication therapy management, and deprescribing. These pharmacist-led interventions have the potential to mitigate adverse outcomes associated with polypharmacy in CKD.

A Systematic Review of the Economic Burden of Proton Therapy in Head and Neck Cancer

BACKGROUND

Radiation therapy is used to treat head and neck cancer (HNC) patients. Proton beam therapy (PBT) is one of the newer treatment options. This systematic review will describe the cost and cost-effectiveness of PBT compared with other first-line treatment options based on available literature and provide a better understanding of its usage in HNC in the future.

METHODS

This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Systematic searches were conducted in PUBMED, EMBASE and SCOPUS till February 2022. Original pharmacoeconomic articles written in English that considered PBT for HNC were included; the title, abstract and full text of the search items were screened. The included studies were critically appraised using the Drummond Checklist followed by data extraction.

RESULTS

Eight of the ten included studies were of good quality; most were cost-effectiveness or cost comparison studies and used the Markov model and lifetime horizon. The dominant comparator was intensity-modulated radiotherapy. The willingness to pay threshold ranged from $30,828 to $150,000 per QALY. The incremental cost-effectiveness ratio (ICER) was between $4,436.1 and $695,000 per QALY. In HNC patients with human papillomavirus infection, the ICER was lower ($288,000/QALY) from the payer's perspective, but much higher ($390,000/QALY) from the societal perspective.

CONCLUSION

Our systematic review showed that appropriate patient selection can make PBT cost-effective. HPV-associated tumors can be cost-effectively treated with PBT. From the payer's perspective, PBT is a cost-effective treatment option. In younger patients, PBT can result in lesser incidence of adverse effects, and hence, can reduce the subsequent need for long-term supportive care. Lower fractionation schedules can also make PBT a cost-effective treatment.

Characteristics and Quality Appraisal of the Economic Evaluations Done in Ethiopia: A Systematic Review

BACKGROUND

Health economic evaluation identifies, measures, values, and compares alternative strategies to efficiently allocate scarce resources. The validity, methodological quality, and generalizability of economic evaluations must be assessed, as poorly designed studies can lead to incorrect conclusions. Therefore, this study aimed to evaluate the quality and characteristics of published economic evaluations done in Ethiopia, using the Quality of Health Economics Studies (QHES) and Consolidated Health Economic Evaluation Reporting Standards (CHEERS) instruments.

METHODOLOGY

Various electronic databases were searched using different keywords. We included only original studies conducted in Ethiopia that evaluated the cost and consequences of at least two health interventions. Abstracts, treatment guidelines, reviews, expert opinions, and studies that included other countries were excluded. Two reviewers independently evaluated each study using the QHES and CHEERS instruments and any disagreements were then resolved by a third reviewer.

RESULT

The study included 21 studies published between 2002 and 2021. HIV was the most frequently evaluated medical condition, examined in four (19.06%) of the 21 studies. Seventeen of the studies (80.95%) compared healthcare services or programs, while the other four examined pharmaceutical products. Cost-utility analysis was the economic evaluation technique used in 14 studies (66.67%). Of the studies that disclosed their funding sources, foreign institutions were involved in funding 71.43% of them. Disability-adjusted life-year (DALY) was an outcome metric used in nine (42.86%) studies. The average QHES score of the studies was 82%. Fourteen studies had QHES scores of ≥75% and two had scores of <50%. The studies evaluated using the CHEERS instrument ranged in quality from 42.9% to 92.9%, with an average of 78.23%.

CONCLUSION

Our study revealed that Ethiopia lacks health economic evaluations, particularly on non-communicable diseases. This indicates that the economic evaluation of healthcare interventions in Ethiopia is still in its early stages. Additionally, Ethiopian institutions have played a very limited role in funding research, highlighting the importance of active participation from local institutions.

A Study of Drug Utilization Pattern and Pharmacoeconomic Analysis of Immunosuppressant Drugs in Patients With Skin Disorders in a Tertiary Care Hospital in Bihar

Aims The cost-effective therapy of immunosuppressant drugs in dermatological conditions will not only lead to adherence to rational prescribing but will also increase patient compliance with fewer dropouts due to cost factor. Thus, this study was done to determine and compare the drug utilization pattern, prescribed daily dose/defined daily dose (PDD/DDD) defined by WHO, and the cost-effectiveness ratio of different immunosuppressants.  Methods and material Prescriptions for patients with skin disorders prescribed with any one systematic or topical immunosuppressant were collected. The utilization of drugs in different skin disorders was expressed as frequency and percentage. PDD was compared with DDD as per the WHOCC-Anatomical Therapeutic Chemical (ATC)/DDD index. The pharmacoeconomic analysis was done using a cost-effectiveness ratio. Statistical analysis Descriptive statistics were used to calculate percentages, frequency, and 95% CI. The cost-effectiveness ratio in terms of SFDs (symptom-free days) was defined as the total cost of the initial antibiotic during the study period divided by the number of SFDs (cost/ SFD) and was expressed as mean±standard deviation, and the Kruskal-Wallis test was used to determine statistical significance of difference. Results Immunosuppressants were prescribed in 117 (19.12%) prescriptions out of a total of 612 prescriptions. Deflazacort was the most utilized systemic immunosuppressant prescribed in 27.18% of cases and was commonly prescribed for irritant contact dermatitis (ICD) and allergic contact dermatitis (ACD) followed by prednisolone and betamethasone. Tacrolimus was the most utilized topical immunosuppressant prescribed in 15.90% of patients and was commonly used for ICD and vitiligo followed by clobetasol and mometasone. Betamethasone, prednisolone, clobetasol, and mometasone had better cost-effectiveness. PDD/DDD of all immunosuppressants was less than one except prednisolone, which had a PDD/DDD ratio of 3.52. Conclusions The cost-effectiveness of steroids has the advantage of providing better patients' adherence to pharmacotherapy, but over-prescribing could also lead to long-term adverse effects of steroids. Pharmacovigilance research should also incorporate pharmacoeconomic analysis to determine the relation between these two aspects.

Cost-minimization analysis of escitalopram, fluoxetine, and amitriptyline in the treatment of depression

INTRODUCTION

Escitalopram, fluoxetine, and amitriptyline are the drugs commonly used in the treatment of depression. The pharmacoeconomic evaluation of these drugs becomes relevant as they are prescribed for a long period of time, and depression causes a significant economic burden. The cost-minimization study would contribute to bringing down the annual treatment costs, leading to better medication adherence and ultimately better patient outcomes.

MATERIALS AND METHODS

All drug prices are mentioned in Indian National Rupee (INR). All expenses are based on 2022 pricing. No cost discounting was used because all expenditures were calculated over a year. We considered hypothetical scenarios where the patient was prescribed the lowest possible dose for depression, an equivalent antidepressant dose, a defined daily dose, and the maximum acceptable therapeutic dose for depression.

RESULTS

Annual average treatment costs of amitriptyline, escitalopram, and fluoxetine in patients with depression at baseline with equivalent dosing as mono-drug therapy were 2765.53, 2914.78, and 1422.72 rupees (INR), respectively. Savings were high when the patient was shifted to fluoxetine from either escitalopram or amitriptyline. The savings from switching to fluoxetine were 50.66% and 56.42% from escitalopram and amitriptyline, respectively.

CONCLUSION

The choice of an antidepressant depends on multiple aspects, among which the cost of treatment plays a crucial role. Among the drugs compared, fluoxetine seems to offer greater value for money. The study emphasizes that selective serotonin reuptake inhibitors are the most commonly prescribed antidepressants not only because of their favorable pharmacological profile but also because of their affordability.

Evaluation of pharmaceutical care services in the Middle East Countries: a review of studies of 2013-2020

INTRODUCTION

Pharmaceutical care services (PCs) have evolved significantly over the last few decades, with a greater focus on patient's safety and proven effectiveness in a wide range of contexts. Many of the evidence supporting this technique comes from the United States, the evaluation and adoption of (PCs) which differ greatly across the globe.

OBJECTIVE

The goal of this study was to identify and assess the efficacy of pharmaceutical care services in various pharmaceutical aspects throughout seventeen Middle Eastern nations.

METHOD

The Arkesy and O'Malley technique was used to conduct a scoping review. It was conducted using PubMed/Medline, Scopus, Cochrane Library, Springer Link, Clinical Trials, and Web of Science etc. The Van Tulder Scale was utilized in randomized trials research, whereas the dawn and black checklists were used in non-randomized trials research. A descriptive and numerical analysis of selected research was done. The scope of eligible PCs, pharmaceutical implementers, study outcomes, and quality were all identified by a thematic review of research.

RESULTS

There were about 431,753 citations found in this study, and 129 publications were found to be eligible for inclusion after analysing more than 271 full-text papers. The study design was varied, with 43 (33.3%) RCTs and 86 (66.7%) n-RCTs. Thirty-three (25.6%) of the studies were published in 2020. Jordan, Saudi Arabia, and Turkey were home to the majority of the studies (25.6%, 16.3%, and 11.6%) respectively. Thirty-seven studies (19.7%) were concerned with resolving drug related problems (DRPs), whereas 27 (14.4%) were concerned with increasing quality of life (QOL) and 23 (12.2%) with improving drug adherence. Additionally, the research revealed that the average ratings of the activities provided to patients improved every year.

CONCLUSION

Studies in the Middle East continue to provide evidence supporting the positive impact of pharmaceutical care services on both hard and soft outcomes measured in most studies. Yet there was rare focus on the value of the implemented services. Thus, rigorous evaluation of the economic impact of implemented pharmaceutical care services in the Middle East and assessment of their sustainability is must.

Temporal Change in the Remaining Life Expectancy in People Who Underwent Percutaneous Coronary Intervention

Whether percutaneous coronary intervention (PCI) is effective in improving long-term survival in an Australian PCI cohort remains unclear. We aimed to examine the change in the remaining life expectancy for patients who underwent PCI over the past decade. Patient data from the Melbourne Interventional Group were divided into four 3-year periods (2005 to 2007, 2008 to 2010, 2011 to 2013, and 2014 to 2016) for survival analysis. The primary outcome was time to death after PCI. Kaplan-Meier survival curves for overall survival were constructed to estimate the 5-year survival. To extrapolate the overall survival curve to the lifetime time horizon, 6 parametric survival distributions were fitted to the individual patient-level data against the Kaplan-Meier curve. The best fit distribution was selected based on goodness-of-fit statistics and expert opinion. The combination of annual mortality post-PCI from the parametric survival analysis and the background mortality by age informed the overall mortality rate. The life expectancy was compared with the general Australians. In addition, the utility weight of post-PCI patients was used to estimate the quality-adjusted life years gained. A total of 27,301 patients with a mean age of 64.4 ± 12 years were included. The base-case results showed that over the 4 time periods, the remaining life expectancy for patients aged 64.4 years on average at the time of PCI remained relatively stable except for period 4: 18.12 years (2005 to 2007), 17.56 years (2008 to 2010), 18.39 years (2011 to 2013), and 17.25 years (2014 to 2016), respectively. The quality-adjusted life years gained showed a similar trend: 14.86 (2005 to 2007), 14.40 (2008 to 2010), 15.07 (2011 to 2013), and 14.13 (2014 to 2016) separately. In conclusion, the widened gap in life expectancy in post-PCI patients versus the general Australian over the 2014 to 2016 period suggests the need for improved implementation of prevention strategies for coronary heart disease. Enhanced disease management after PCI that lowers residual mortality risk is recommended to extend the survival of patients with coronary heart disease.

Pharmacist Intervention in Portuguese Older Adult Care

Healthy ageing has become one of the most significant challenges in a society with an increasing life expectancy. Older adults have a greater prevalence of chronic disease, with the need for multiple medications to appropriately control these issues. In addition to their health concerns, ageing individuals are prone to loneliness, dependence, and economic issues, which may affect their quality of life. Governments and health professionals worldwide have developed various strategies to promote active and healthy ageing to improve the quality of life of older adults. Pharmacists are highly qualified health professionals, easily accessible to the population, thus playing a pivotal role in medication management. Their proximity to the patient puts them in a unique position to provide education and training to improve therapeutic adherence and identify medication-related problems. This paper aims to address the importance of Portuguese community pharmacists in the medication management of older adults, emphasising their intervention in health promotion, patient education, medication-related problems, deprescription, dose administration aids, and medication review and reconciliation. We also discuss home delivery services and medication management in long-term care facilities.
