1.ACTA at the crossroads.
Acta Medica Philippina 2026;60(1):5-6
Academic publishing is at a critical juncture. The challenges faced by the academics are mired in controversy. Among theseare three hotly debated concerns. First is the issue of whether technological innovations such as artificial intelligence (AI)improves research efficiency or if its use sacrifices research integrity.Another is the controversy between paywall publishingand open access. Lastly, adapting an appropriate business model for sustainability is a contentious issue and the choice betweena commercial or a university-based publishing platform is a difficult one.
Traditional models of scientific investigation relied on tedious intellectual calisthenics in all aspects of research —identifying research gaps, reviewing of published literature, devising valid methodology, collecting data, analysing results, and,finally, drawing conclusions. With the advent of powerful tools employing artificial intelligence, these heavy tasks are efficientlycarried out. The dilemma lies in determining which parts of the work can be attributed to the authors and which are ascribedto the output of large language models (LLMs) and other automated assistance employed.Despite requiring adequate vettingby experts of these AI-aided output, many in the scientific community still question these methods. Can research employingAI be considered honest work? Will full disclosure answer doubts as to the integrity of the scientific work?
Indeed, LLMs just gather information that is already out there, albeit more efficiently. After all, science progresses bystanding on the shoulder of giants. AI makes such work comprehensive and efficient. Standing on those proverbial shoulders,however, require access to prior work, hence our next challenge in academic publishing--open access versus paid access.Paywalls limit the benefits of valuable research to institutions and universities with the capacity to pay. Excluded from these arethose from low resourced countries, with nations from the global south being affected disproportionately. Additionally, whilenumerous authors appreciate the features of open access as it improves their impact and visibility, many feel unduly burdenedsince the cost of publishing in this format is passed on to them.
This brings us to our third issue: who bears the cost of academic publishing? Indeed, it is a lucrative industry, generatingan annual revenue of US$19 billion and an estimated 40 percent profit margin. Many, however, find fault in this businessmodel as concerns about the profit motives of the commercial publishers far overshadow their sustainability goals.
How do we navigate this landscape of controversies? We, at the ACTA, as part of the community of scholars, would needto clarify our mission. Our goals for this publication should be consistent with our values. These values, such as scientific rigor,integrity, and accountability, should be reflected in our policies. We should be cognizant of the role we play in national scientificdiscourse while we endeavor to make an impact in the global scene. We are accountable to our stakeholders — nurturingearly career scholars, supplying evidence to health policymakers, and being accountable to those who provide resources tosustain us. This stewardship is essential so that ACTA will stand shoulder to shoulder with the giants on which science buildsupon to benefit future generations.

2.From data to practice: Why translating research findings to real-world outcomes needs more implementation studies.
Acta Medica Philippina 2026;60(8):5-6
Walking through the wards of a crowded public hospital and seeing suffering and tragedy from easily preventable conditionsmakes one wonder what it takes for a facility to change the outcomes. The evidence is there, and guidelines have beendeveloped from it; yet practices remain difficult to change—whether in screening, prevention, treatment, or rehabilitation.
Recently, the Department of Health has put up a compendium of clinical practice guidelines (CPG) crafted accordingto the standards set by the Manual for Clinical Practice Guideline Development of DOH-Philhealth.Guidelines stipulatethat dissemination and implementation be considered, and applicability issues are discussed. The uptake of the guidelinesshould be evaluated, and facilitators and barriers should be identified. Thus, there is a need for implementation andapplicability studies to assess how effective guidelines are. For breast cancer, the Philippine Guidelines were published in 2022and updated in 2026.Identified as barriers against implementation are financial constraints and out-of-pocket costs. Actahas since responded to these concerns by publishing articles on financing cost assessment, and in this issue, by Mondragonand co-authors, an “Assessment of Out-of-Pocket Expenditure of HER2-Positive Breast Cancer Patients in a Tertiary CancerCenter and Private Clinics in the Philippines.”
These types of studies are necessary in the translation of evidence to practice, allowing organizations to adopt, scale,and sustain recommendations to real-world settings.
Where CPGs on malnutrition cite resource constraints as the only significant barrier for implementation, the article byde Luna and co-authors on the “A Qualitative Program Evaluation Study on the Perceived Impact of Health and NutritionPrograms among Beneficiaries of a Civil Society Organization in the Philippines” in this issue of the Acta add fear ofsustainability by families and competition from readily accessible instant food of poor nutritional value as barriers in implementingsuch programs.
These studies help us go beyond information dissemination of evidence-based practice to create pathways for impactfulintegration of recommended interventions. Implementation studies sharpen our analysis and focus our efforts on strategies thatcan help pilot, roll out, and scale up guidelines.
New modalities to carry out recommendations can also be part of how guidelines are implemented in the communitysetting. Where the Philippine Academy of Rehabilitation Medicine (PARM) recommends early home-based rehabilitation,the Stroke Society of the Philippines recommends telerehabilitation to augment the efforts of care providers.The articleby Laxamana and co-authors in this issue on “The Acceptance of Stroke Telerehabilitation among Rehabilitation Providersand Consumers in Two Tertiary Hospitals in the Philippines” not only identifies but also provides suggestions to addressimplementation barriers.
We support and encourage articles on implementation science. These works provide tools to convert evidence into outcomes.These transform organizations and help us accomplish meaningful, lasting structural change that should come withoutany delay to provide relief to our patients in our crowded public wards.

BACKGROUND AND OBJECTIVES
Non-Hodgkin Lymphoma (NHL) ranks 11th in cancer incidence and mortality in the Philippines with the combination chemotherapy composed of Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone (CHOP) being commonly used as treatment. However, the addition of Rituximab to CHOP (R-CHOP) has been shown to exhibit higher response rates and longer remissions, potentially improving quality of life. Currently, there is conflicting evidence on the cost-utility of CHOP versus R-CHOP. The study aimed to describe the patient- and country-specific factors, and treatment modalities used for NHL and systematically review cost-utility evidence of R-CHOP versus CHOP in adult NHL patients.
METHODSA systematic literature search of cost-utility studies on R-CHOP versus CHOP for NHL treatment was performed on eight databases: PubMed/MEDLINE, Scopus, Web of Science, EBSCOHost, Cochrane, York Research Database, Centre for Reviews and Dissemination Database, and HERDIN, where 607 studies were identified. Upon screening using an eligibility criteria, 10 studies were included and critically assessed using four appraisal tools: CHEERS, Drummond, Cooper, and ECOBIAS. These were performed independently by two authors with a third author assisting to help reach a consensus.
RESULTSAll studies from high-income countries (HICs) (n=8) and low-middle-income country (LMIC) (n=1) suggested that R-CHOP was more cost-effective for NHL treatment than CHOP in terms of utility outcomes. The study conducted in a low-income country (LIC) (n=1) suggested the opposite, favoring CHOP over R-CHOP. Methodological differences such as perspective, discount rate, willingness-to-pay (WTP), time horizon, and economic model were observed. Methodological limitations include completeness of data reported and credibility of sources used.
CONCLUSIONThe results of this review shall be interpreted with caution as those favoring R-CHOP over CHOP for NHL treatment in terms of cost-utility were concentrated in HICs. More economic evaluations from LICs, LMICs, and upper-middle income countries (UMICs) are needed for a robust conclusion. Additionally, establishing a universally recognized guideline for economic evaluations is essential to guide researchers effectively.

OBJECTIVE
To perform a cost comparison of the 5-year total direct medical costs of iStent inject® W vs. trabeculectomy vs. glaucoma medications for the treatment of primary open-angle glaucoma, with and without phacoemulsification, from the perspective of Filipino patients.
METHODSThis cost-comparative analysis compared total private sector costs of surgery, post-operative care, and medication usage over 5 years on combined phacoemulsification (combined) or standalone (SA) procedures using iStent inject W, trabeculectomy, and glaucoma medications for the general population and senior citizens/individuals with disabilities. Data, including unit costs and frequencies, were obtained from published literature and local primary research. Scenario analysis consisted of three payment models: 100% out-of-pocket (OOP), coverage from PhilHealth public health insurance, and combined subsidies from both private and PhilHealth insurance.
RESULTSiStent inject W was less costly than glaucoma medications in all scenarios and patient populations. When compared with trabeculectomy, iStent inject W, was less costly in all patient populations in the OOP scenario, providing savings of 5% for SA procedures and 5% to 6% for combined procedures. It was also less costly as a combined procedure in all populations in the combined private health and PhilHealth insurance scenario, offering 6% savings in the general population and 9% in elderly and disabled patients. However, it was costlier by 1% in the PhilHealth scenario. As an SA procedure, it was costlier vs. trabeculectomy in both populations in the PhilHealth and PhilHealth plus private health insurance scenarios by 18% to 22% and 101% to 109%, respectively. The highest incremental cost for iStent inject W was US$1,662 vs. trabeculectomy as an SA procedure in the general population under the combined private health and PhilHealth insurance scenario.
CONCLUSIONFor Filipino glaucoma patients who are treated in the private sector, iStent inject W, whether combined or as an SA procedure, may be cost-saving compared with glaucoma medications over a 5-year period; however, it may be costlier compared with trabeculectomy depending on health insurance coverage scenarios.

BACKGROUND
The Division of Colorectal Surgery at the Philippine General Hospital (PGH) conducts hundreds of surgeries annually for benign and malignant colorectal conditions. Since 2019, the Division has implemented an Enhanced Recovery After Surgery (ERAS) program to improve patient outcomes. However, its impact on hospital costs—critical for a government hospital—has not yet been studied.
OBJECTIVEThis study aimed to evaluate the effect of ERAS on healthcare costs for elective colorectal surgeries performed at PGH in 2021.
METHODSA retrospective observational study was conducted on adult patients who underwent elective colorectal surgeries under the ERAS protocol in 2021. Medical and billing records were retrieved using the hospital’s electronic medical records (EMR) system, excluding cases with incomplete data. Procedures were categorized by type [stoma closure, colonic or rectal resection, reversal of Hartmann’s, or cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC)] and surgical approach (open, laparoscopic, or robotic). Costs were classified into diagnostics, facility fees, medications, surgery, and hospital supplies. ERAS compliance rates were extracted from the online ERAS Interactive Audit System (EIAS), and linear regression analysis was performed.
RESULTSAmong 114 elective colorectal surgeries, records for 90 cases were analyzed. Surgery-related expenses accounted for the highest mean hospital costs across all procedure types. An inverse correlation between ERAS compliance and total cost was observed for open surgeries, with statistically significant reductions in stoma closures and open colon resections (p-value: 0.0213 and 0.0134, respectively). However, minimally invasive surgeries (MIS) did not demonstrate cost reductions with increasing ERAS compliance, likely due to additional expenses associated with advanced equipment. Linear regression indicated that higher compliance rates generally led to decreased hospital costs.
CONCLUSIONStandardized care through ERAS has been associated with cost savings compared to traditional perioperative management. This study supports the conclusion that higher ERAS compliance can reduce hospital costs in open colorectal surgeries. However, the higher costs of MIS procedures, driven by equipmentrelated expenses, may offset potential savings from ERAS adherence. Further research is warranted to explore the cost implications of ERAS in MIS cases.

BACKGROUND AND OBJECTIVE
Oral ivermectin is recommended as an alternative to topical permethrin in Japanese, European, and CDC-STI guidelines for treating classic scabies. The combination of oral ivermectin and topical permethrin is also used in some settings. Partial economic evaluations conducted in India and Egypt have conflicting results, and no cost-effectiveness analysis in the Philippines has compared ivermectin-based regimens to permethrin for scabies treatment. We aimed to determine the cost-effectiveness of oral ivermectin, alone or in combination with permethrin, compared to permethrin, in the treatment of Filipino adult patients with classic scabies.
METHODSWe used a decision tree model to estimate the cost-effectiveness of two regimens, oral ivermectin alone or in combination with permethrin, compared with permethrin to treat adults and children aged five years and older with classic scabies in the outpatient setting from the household perspective in the Philippines. We estimated total costs and disability-adjusted life years (DALYs) over a one-month follow-up. Input parameters were obtained from secondary data, such as effect estimates for probabilities of clinical outcomes from a network meta-analysis, DALYs from the Global Burden of Disease 2019, and prevailing market cost in the Philippines (DPRI 2022 with recommended markup by DOH, and leading drugstores) as of August 2022. We computed for incremental cost-effectiveness ratio (ICER) and net monetary benefit (NMB) to determine which of the interventions are cost-effective. Univariate and probabilistic sensitivity analyses, and scenario analyses were conducted to assess the impact of parameter and structural uncertainty.
RESULTSIvermectin-based regimens are suggested to be likely cost-saving compared to permethrin in the Philippine outpatient setting. Base case analysis showed that oral ivermectin had higher cost-savings (change in cost, -1,039.31; change in DALYS, 0.00027), while combination oral ivermectin/permethrin had higher DALYs averted (change in cost, PhP -1,019.78; change in DALYs, 0.00045), compared to permethrin. Combination oral ivermectin/permethrin (56%) was the most cost-effective, followed by oral ivermectin (44%) compared to permethrin (0%) through probabilistic sensitivity analysis. Estimates for ivermectin were sensitive to risk of cure for ivermectin vs permethrin using 1-way deterministic sensitivity analysis. Oral ivermectin was favored over combination oral ivermectin/permethrin at all thresholds based on the cost-effectiveness acceptability curve.
CONCLUSIONBoth ivermectin-based regimens seem to be cost-saving compared to permethrin in the treatment of classic scabies in the Philippine outpatient setting. Clinicians may consider oral ivermectin, alone or in combination with permethrin as an alternative first-line or second-line treatment depending on patient preference, adverse event risk profile, availability, and economic capacity. This needs to be confirmed using primary data from Filipino patients to enhance the robustness of the findings and support evidence-based local decision-making in different settings. Less uncertainty in modelled parameters can give greater confidence in the results, which can be adopted for budget impact analysis and allow more rational resource allocation. Value of information analysis can be done to determine whether the expense of future RCTs or surveys in Filipinos to collect primary data is worth it. The cost of reducing uncertainty, if deemed worth the cost of further studies, may facilitate population-level decision-making and budget planning. Findings may further inform practice guideline development, coverage decisions, and national control program planning by providing the most cost-effective scabies intervention.

OBJECTIVES
During the early COVID-19 pandemic (2020 to mid-2021), the Philippine government relied on nonpharmaceutical interventions such as lockdowns and Enhanced Community Quarantine (ECQ). With the emergency use authorization of vaccines, assessing their potential impact became essential. This study develops a Philippine model to evaluate the epidemiologic and economic effects of COVID-19 vaccination, estimating its impact on mortality, hospitalization, and mild/asymptomatic cases under various prioritization strategies, including booster doses and the presence of variants of concern.
METHODSA dynamic transmission model (DTM) with an SEIR (Susceptible-Exposed-Infected-Recovered) structure was calibrated using local data, including case numbers, deaths, seroprevalence, vaccination coverage, and intervention costs. The model’s outputs informed a cost-effectiveness analysis (CEA) from health system and societal perspectives over a two-year horizon. Incremental Cost-Effectiveness Ratios (ICERs) were calculated, with costs adjusted to 2020 prices and discount rates of 3%-10% applied. Sensitivity analyses, including one-way and probabilistic approaches, assessed robustness, while a budget impact analysis (BIA) estimated government expenditures in 2020 and 2021.
RESULTSWithout vaccination, daily cases could have peaked at 400,000 between February and May 2021. A vaccination campaign was projected to reduce cases to around 20,000, significantly lowering mortality.
From the health system perspective, the estimated cost without vaccination was PhP 14.46 trillion, with 93.83 million QALYs. With vaccination, costs dropped to PhP 2.36 trillion, while QALYs increased to 101.79 million. From the societal perspective, costs were PhP 14.68 trillion without vaccination and PhP 2.38 trillion with vaccination, with the same QALY outcomes.
CEA results confirmed that vaccination was cost-saving, with ICERs of -PhP 1,520,727.28 per QALY (health system) and -PhP 1,546,171.63 per QALY (societal). Sensitivity analyses supported these findings, with oneway sensitivity analysis showing minimal impact from parameter changes and probabilistic sensitivity analysis confirming cost-saving outcomes. The BIA estimated government expenditures of PhP 983.45 billion in 2020 and PhP 1.47 trillion in 2021 for the vaccine scenario, lower than the no-vaccine scenario.
CONCLUSIONIndeed, our modeling has shown that COVID-19 vaccines could mitigate the spread of COVID-19 and provide good value for money.

OBJECTIVES
The burden of oral diseases is high in the Philippines. The global burden of disease study in 2019 estimated that 44 million Filipinos are affected by oral disorder. More specifically, 29 million Filipinos have untreated dental caries. Outpatients' dental health services are not covered by PhilHealth benefit package. There is a need to include key oral health interventions such as basic prevention and treatment in PhilHealth benefit package to be delivered at the primary health care settings (WHO TSA 153980). The study aimed to determine the incremental cost-effectiveness ratio (ICER) of a set of oral health care services to be delivered at different levels of health care within a comprehensive PhilHealth benefit package.
METHODSThis study evaluates the cost-effectiveness of including basic oral health services in the PhilHealth benefit package using a Markov modelling approach. The target population consists of Filipino adults and children at risk for dental diseases who are potential beneficiaries of PhilHealth. The intervention under consideration includes dental consultation, oral prophylaxis, topical fluoride application, silver diamine fluoride application, dental filling, and tooth extraction. The comparator is the current standard of care, which involves out-of-pocket payments for oral health services or limited access to subsidized dental care. The primary outcomes assessed include the incremental costeffectiveness ratio (ICER) per quality-adjusted life year (QALY) gained. A Markov model was constructed with a time horizon of 50 years to simulate the lifespan of Filipinos up to the average life expectancy of 70 years old, using a cycle length of one year to reflect disease progression and treatment effects overtime. Model parameters were derived from literature and expert opinion. Sensitivity analyses, including one-way and probabilistic sensitivity analyses, were conducted to assess uncertainty in model inputs. The analysis was carried out from a societal perspective incorporating direct medical and non-medical costs, and indirect costs.
RESULTSA Markov model showed that a subsidized package is a cost-effective approach compared to the current situation of no subsidy, with an ICER of PhP 75,636 (1,535.76 USD) per disability adjusted life year (DALY) averted. The computed ICER was considered good value for money as it was below 2021 GDP per capita of the Philippines of PhP 174,286 (3,538.80 USD). One-way sensitivity analysis showed that the cost of preventive treatment had the most significant impact on the model, and a price threshold of greater than PhP 3,062 (62.17 USD) for preventive treatment will render the subsidized package no longer cost-effective. The budget impact analysis showed a 1.63% increase in budget annually with the current situation of no subsidy. Rolling out a subsidized oral health package will entail a significant increase in government expenses during the first year but a decreasing trend of 1-2% annually for the following years as the program takes its effect.
CONCLUSIONA subsidized oral health package is a costeffective approach from a societal perspective. It will entail a significant increase in government expenditure during the start of its roll out but will eventually result in a decreasing trend of expenses as the years progress.

BACKGROUND
The World Health Organization (WHO) estimates that in 2015, approximately 325 million or 4.4% of the global population were living with chronic hepatitis B or hepatitis C infection. In the same year, around 1.34 million died from this disease.
OBJECTIVESThis study aimed to estimate the burden of hepatitis B in the Philippines and to determine the costeffectiveness of possible interventions.
METHODSThis study utilized the Center for Disease Analysis Foundation’s (CDAF’s) mathematical disease burden model of hepatitis B. Model inputs were collected using literature review, key informant interviews, expert panel interviews, and records review, and were validated through a series of round table discussions with experts.
RESULTSResults show that in 2017, the prevalence of chronic hepatitis B infection in the Philippines was 9.7%, equivalent to 10 million infected individuals. Although the model projects a decreasing trend in chronic hepatitis B virus (HBV) infections, liver-related mortality and morbidity due to these viruses are expected to rise if the status quo is maintained. Results show that substantial increase in government subsidy for WHO elimination scenarios would be required to achieve cost-effective outcomes.
CONCLUSIONHepatitis B remains a huge problem in the Philippines. The HBV modelling exercise reveal that it will be worthwhile and cost-effective to adhere to the WHO elimination targets. A substantial financial investment will be necessary to do so, specifically a significant scale up in the screening, diagnosis, treatment, and monitoring of patients with HBV. While this modelling exercise does not yield burden of disease as accurate as a prevalence survey, experts consulted in the round table discussions agreed with the modelling inputs.
