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.

METHODS

A 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.

RESULTS

Without 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.

CONCLUSION

Indeed, our modeling has shown that COVID-19 vaccines could mitigate the spread of COVID-19 and provide good value for money.

Background and Introduction. The RxBox is a telemedicine device that measures and transmits vital signs to remote experts. It has been deployed to primary care health centers (PCHC) in the Philippines serving disadvantaged populations, to decrease morbidity and mortality due to common diseases and poor access to care. Factors affecting its adoption by healthcare workers is unknown.

Materials and Methods. The study determined social and behavioral factors that affect adoption of a telemedicine device into the clinical workflow using the Unified Theory of Acceptance and Use of Technology (UTAUT) framework. This is a mixed methods research using review of records, survey and focused group discussions.

Results and Discussion. RxBox telemedicine devices were installed in 79 primary care health centers (PCHC) and were used a total of 15,705 times within the study period. An ordinary least squares regression analysis using the combined site and individual-level data showed that among the UTAUT parameters, only compatibility, facilitating conditions, and social factors have significant relationships with intent-to-use of the RxBox. The innovation assisted primary care health workers in their clinical responsibilities, improved the stature of their PCHC in the community, and helped in the care for patients. Training and technology support after deployment as well as encouragement by peer and champions (the PCHC physician, local government leaders) reinforced continuous use after training. Users described the experienced improvements in quality of services provided by the PCHC and the consequent benefits to their patients.

Conclusions. These factors should be accounted for in designing strategies to reinforce health workers' attitudes and enhance support towards acceptance and use of novel telemedicine devices into clinical routine in local health centers. Lessons are immediately useful for local leaders in low- and lower middle-income countries that suffer disproportionately from unnecessary maternal deaths and mortality due to non-communicable diseases. This contributes to the body of knowledge and should bolster national-level advocacy to institute an enabling policy on telehealth Information Communication Technology (ICT) and use of Filipino innovations towards health systems strengthening. Results can be used by implementers, evaluators, and regulators of health ICT, especially in resource-poor settings. Likewise, the study can encourage more research in the field to spur more dynamic local health ICT and biomedical device industries.

Primary Health Care

OBJECTIVE: X-linked dystonia parkinsonism (XDP) is an adult-onset, progressive and debilitating movement disorder described among Filipino males from Panay Island. The available oral medications have been ineffective. While chemodenervation with botulinum toxin A works and deep brain stimulation surgery is promising, these are not affordable for the vast majority of patients. Thus, we decided to look into the efficacy, safety and tolerability of levodopa+carbidopa (levodopa) versus placebo among patients with XDP.

METHODS: This was a double blind, randomized, placebo-controlled clinical trial. Patients were randomized to receive levodopa or placebo for 6 months. The dose was increased gradually until 1000 mg levodopa/day is reached or until side effects appear.

RESULTS: A total of 86 out of 94 randomized patients (91.5%) were included in the intention-to-treat cohort for the primary efficacy analysis. Nineteen patients (9 in levodopa, 10 in placebo) dropped out or were lost to follow up. There was no significant difference in the baseline and last visit Burke Fahn Marsden Dystonia Rating Scale and the part III of the Unified Parkinson's Disease Rating Scale scores between levodopa and placebo. The most common adverse events in the levodopa group were increased movements, pain and nausea/ vomiting.

CONCLUSION: While levodopa is safe and well-tolerated, it does not have any effect in alleviating the dystonia or parkinsonism in XDP.

BACKGROUND: Dysphagia is common among post-stroke patients,causing disability due to malnutrition and pneumonia. Repetitive transcranial magnetic stimulation (rTMS) is a novel treatment modality to address this complication.

OBJECTIVE: The study aimed to compare real versus sham rTMS in treating post-stroke dysphagia.

METHODS: PubMed, Ovid, ClinicalKey, Herdin, and Google Scholar databases were searched from their earliest record to 31 July 2015 for randomized controlled trials that used rTMS to treat post-stroke dysphagia. The Jadad scale was used to assess the quality of the studies. The weighted mean difference (WMD) between baseline and post-treatment mean for Penetration Aspiration Scores (PAS) measured in the experimental and control groups were extracted for subsequent meta-analyses.

RESULTS: Three studies were analyzed. The WMD in PAS score between rTMS and control using liquid bolus two weeks after treatment in two good quality studies was -1.14 (95% confidence interval (CI) = -1.80 - -0.48, P = 0.001, I2 = 0.0%), and after four weeks was -1.83 (CI = -3.22 - -0.44, P = 0.010, I2 = 0.0%).

CONCLUSION: Treatment of post-stroke dysphagia with rTMS improved PAS on subgroup analyses of studies using liquid bolus after two weeks, and between real and sham treatment after four weeks.?

BACKGROUND: Medication errors are preventable events that can cause or lead to inappropriate drug use. Knowing the prevalence and types of errors can help us institute corrective measures and avoid adverse drug events.
OBJECTIVE: This study determined the prevalence of medication errors and its specific types in the four main service wards of a tertiary government training medical center.
METHODS: This is a retrospective, descriptive chart review study. From the master list of admissions, systematic sampling was done to retrieve the required number of charts. Relevant pages such as order sheets, nurses' notes, therapeutic sheets were photographed. For prolonged admissions, only the first 7 days were reviewed. Each chart was evaluated by two people who then met and agreed on the errors identified.
RESULTS: The overall prevalence of medication errors is 97.8%. Pediatrics had the most (63.3/chart), followed by Medicine, OB-Gynecology, and Surgery (7.3/chart). The most common type of errors identified were prescribing, followed by compliance, then administration errors.
CONCLUSION: Medication errors are present in the four main wards in our hospital. We recommend orientation of all incoming first year residents on proper ordering and prescribing of drugs, as well as a prospective observational study to determine true prevalence of all types of medication errors.

Medication Errors

BACKGROUND: Migraine is a highly common disorder that can cause significant disability on an individual, which collectively may lead to a substantial burden for the society. Various expert societies have recommended Acetaminophen/Aspirin/Caffeine (AAC) combination regimen as the first-line drug treatment for migraine attacks; however, there were no pooled evidences summarizing the effectiveness and tolerability of this regimen.
OBJECTIVE: To determine the effectiveness and tolerability assessment of oral AAC combination regimen as an acute treatment for migraine in adults.
METHODS: Relevant studies from inception to March 2014 were searched in Cochrane CENTRAL, MEDLINE, LILACS, Scopus and metaRegister of Controlled Trials. The Cochrane Collaboration's tool for the assessment of risk of bias was employed. Trials that were randomized, double-blind, parallel-group, placebo and active-controlled were included and the data were employed for meta-analysis. To evaluate the quality of evidence, the GRADE approach was utilized for outcomes with sufficient studies and data.
RESULTS: From 225 records identified, 4 trials were included in this review, with a total of 3,608 participants with recorded baseline characteristics. Patient-reported migraine intensity was moderate-severe and the AAC dose used was at 500/500/130 mg. At 2 hours, AAC regimen was statistically different and found to be superior to placebo in terms of pain-free, headache relief, nausea-free, photophobia-free, phonophobia-free and functional disability reduction rates using intension-to-treat analysis. Missing data did not alter the outcome measures generating robust results. Sumatriptan 100 mg was found to be better than AAC in pain-free rate, and phonophobia-free rates at 2 hours. Statistically more patients in the AAC arm experienced "any adverse event" compared to placebo and complaints were commonly nausea and nervousness.
CONCLUSION: For adult individuals with moderate-severe migraine, a fixed oral dose of Acetaminophen/Aspirin/Caffeine (AAC 500/500/130 mg) may be used as first-line therapy for the acute treatment of migraine and is only associated with mild, infrequent adverse events.

BACKGROUND: Locally, understanding and communicating sensory neuropathy may be confounded by a "comprehension gap" during consults and limited "nerve literacy" or knowledge of patients about nerves. This may affect the effectiveness of healthcare.
OBJECTIVE: The study aims to describe the Filipino patients' experience of sensory neuropathy in local terms and their understanding of its causation.
METHODS: A cross-sectional, descriptive study among 24 patients with sensory neuropathy was done using semi-structured individual interviews. The first part elicited Filipino terms and descriptions used to explain their experience. The second part elicited perceived cause pre- and post- consult and perceived body part affected.
RESULTS: The most common descriptors of sensory neuropathy include "manhid", "kuryente", "tinutusuk-tusok", "ngalay", "kirot", and "naninigas". Many would initially identify "pasma" as a cause. Post-consult, many would cease to see it as part of natural ageing and would identify structural explanations such as impingement. They would however attribute it to an affectation of "ugat" which most defined as blood vessels.
CONCLUSION: The abovementioned terms are commonly used to describe sensory neuropathy and can be clinically useful in eliciting symptoms. There is existing confusion with regards to the nerve as a structure involved even after consultation.

OBJECTIVES: The objectives of the research study were to determine ethical guidelines and principles applicable in the practice and research of eHealth and telehealth in the Philippines, how these are applicable to the Philippines, and to differentiate between the ethical issues in research and in clinical practice of eHealth.

METHODS: This research study used: 1) review of ethics manuscripts, guidelines and literature; 2) focused group discussion and key informant interviews of experts; and 3) triangulation. The information sought for the review were- 1) relevant policies, guidelines in eHealth that are pertinent to the discussion of eHealth ethics in the Philippines; 2) components of ethics in eHealth research; and 3) components of ethics in eHealth practice. The framework of the consultation with experts was to identify mechanisms and strategies in incorporating ethics in both eHealthpractice and eHealth research within the following- 1) in reference to existing laws, policies, and guidelines on ethics in medicine and health; and 2) in the context of the Philippine setting.

RESULTS: Based on the review, there are pertinent codes of ethics, applicable laws, policies and guidelines in eHealth, both in the international and local settings. The focus group discussion and key informant interview with experts yielded significant and deeper understanding on how to address the gaps and lapses of ethics applied to eHealth in the country. These recommendations were given which distinguish between the ethics in clinical practice and ethics in the planning and implementation of eHealth systems. There is also a need to resolve the problem of whose primary responsibility the patient is- the referring, commonly referred to as the attending physician in the local community, or the specialist from the center. The proposed resolution was also presented.

CONCLUSION: The study has shown how important eHealth in potentially promoting timely and improved health care access. However, there are still lapses and gaps in the implementation of policies and guidelines on and relating to eHealth in the Philippines as shown by the data culled from the review and the focus group discussions with the experts. With more specific ethical guidelines and relevant policies, the development and practice of eHealth and telehealth will be on its way in bridging the gap and aiding in health systems development in the Philippines, especially with the support of the national government and collaboration of various agencies and stakeholders.

BACKGROUND AND OBJECTIVE: X-linked dystonia parkinsonism (XDP, DYT3, MIM #314250) is a neurodegenerative movement disorder found endemically in the Philippines. An SVA retrotransposon insertion mutation has been described in patients with XDP, which requires Southern analysis for detection. However, this method is costly and time-consuming. Hence we developed a PCR-based method and validated it among our local population.

METHODS AND RESULTS: A total of 58 samples from 58 patients with a clinical diagnosis of XDP were collected. Other samples were from an obligate female carrier, two unaffected male relatives, and two patients with typical Parkinson’s disease. Primers designed to amplify the SVA retrotransposon found in the DYT3-TAF1 gene (NCBI Accession Number AB191243) were used. All patients were positive for the expected 3229-bp product after PCR amplification. The normal control showed a 599-bp product, while the female carrier showed both the 3229 and 599-bp product. Subsequent RFLP analysis using BamHI verified the presence of the SVA retrotransposon insertion mutation. CONCLUSION: Our results show that large-scale PCR-based testing to screen for genetic diseases with a relatively high prevalence such as XDP is possible in our setting. When followed by RFLP analysis, this can provide genetic confirmation of the diagnosis of XDP and facilitate proper genetic counselling and therapy.
Dystonia 3, Torsion, X-Linked

Sex-linked dystonia parkinsonism (XDP, DYT3, "Lubag") is an adult-onset, progressive, debilitating movement disorder first described in Filipino males from Panay Island in 1975. XDP manifests predominantly as torsion dystonia, later combined with or sometimes replaced with parkinsonism. Within the Island of Panay, the preva-lence rate is highest in the province of Capiz, where 1:4000 men suffer from the disorder. There is a high degree of penetrance and generalization. While women often serve as carriers, XDP is not limited to men. An updated XDP Philippine registry (as of January 2010) has identified 505 cases, with 500 males and 5 females. While some report that females may carry a milder form of the disorder, in our experience, both sexes generally follow a similar progressive clinical course.
