OBJECTIVES: This paper was undertaken to explore the relationship of a 4-year period dengue incidence and the interplay of selected spatial factors (i.e., build-up structures, existing land use/cover types, and presence of water networks) in Quezon City, Philippines. It attempts to examine why dengue incidences are higher in some areas, looking at factors such as geographical attributes, livelihood activities, and practices in the area. At the end of this paper, dengue risk maps will be produced to guide local health authorities target specific areas for focused interventions to manage future dengue outbreak in the area.

METHODS: Reports on dengue cases over the 4-year period (2005-2008) from the City's Health Department Office were encoded and exported in ArcGIS 9.1, a Geographic Information Systems (GIS) mapping software technology. Together with the city's environmental conditions, dengue frequencies were mapped out, overlaid, and examined to determine whether or not these environmental factors affect, contribute and link to the dengue occurrence in an area.

RESULTS: After rendering the dengue risk maps, the highest frequency of dengue is evident in the eastern portion of Quezon City covering District II. Overlaying or superimposing dengue frequency layers with the spatial factors being considered in this study has revealed that these factors affect and contribute to the occurrence of dengue in an area. Areas with a number of river networks and built-up structures experience high dengue incidence. Lands used for residential purposes with neighboring commercial/industrial structures also tend to be dengue susceptible. However, the population density factor alone does not necessarily translate to high dengue frequency. Barangays (the smallest administrative divisions of the city) with high recorded dengue frequency are areas within or near dumpsite facilities primarily because of sanitation concerns as well as the type of livelihood and inherent practices of majority of the residents.

CONCLUSIONS: This research provides an understanding of the spatial epidemiology of dengue in Quezon City using GIS as a tool for identifying high risk areas for dengue. Spatial examination has been carried out to determine spatial anomalies (high concentration of incidence) and the spatial makeup of the area that affects or contributes to such anomalies. The role of GIS in public health decision-making is evident in identifying high risk areas and creating dengue risk maps. Local health authorities will be in a better position to target priority areas and decide where to put scarce resources for programs and projects that will address further disease outbreaks.

BACKGROUND: There is a perceived need among policymakers and other actors in the local health system to better address the challenges in financing healthcare, in general, and chronic or debilitating conditions, in particular, in order to develop appropriate policy and program responses.
OBJECTIVE: This paper aimed to present perceived issues and challenges in financing schizophrenia and colorectal cancer in the Philippine context, as identified by stakeholders.
METHODS: Verbatim transcription of the proceedings of a moderated discussion of stakeholders in schizophrenia and colorectal cancer care was analyzed for themes on challenges and recommendations in the financing of the two conditions in the local setting.
RESULTS: A total of 28 stakeholders representing healthcare providers, professional organizations, health maintenance organizations, patient support groups, and government participated in the meeting. Three main issues on financing debilitating conditions were identified by participants: a) government support for the two conditions is currently limited; b) coverage by third-party payors for schizophrenia or colorectal cancer is either absent or restricted; and c) the process of accessing medicines or alternative modes of financing for healthcare was perceived to be disparate and inconvenient for patients and their caregivers. Participants also provided recommendations in improving the mechanism of healthcare financing.
CONCLUSION: The general picture that emerged from this moderated discussion pointed to limitations in the prevailing mechanisms for financing schizophrenia and colorectal cancer in the Philippines. Improvements in the current financing mechanisms, and identification of alternative modes, is necessary to ensure universal health coverage.

Background and Objectives: Mechanical ventilators are essential albeit expensive equipment to support critically ill patients who have gone into respiratory failure. Adequate numbers should always be available to ensure that a hospital provides the optimal care to patients but the number of patients requiring them at any one time is unpredictable. Finding therefore the best balance in providing adequate ventilator numbers while ensuring the financial sustainability of a hospital is important. Methods: A quantitative method using Monte Carlo Simulation was used to identify the optimal strategy for acquiring ventilators in a large private tertiary medical center in Metro Manila. The number of ventilators needed to provide ventilator needs 90% of the days per month (27/30) was determined using historical data on ventilator use over a period of four years. Four acquisition strategies were investigated: three ownership strategies (outright purchase, installment, and staggered purchase) and a rental strategy. Return on Investment (ROI), Internal Rate of Return (IRR), Modified Internal Rate of Return (MIRR), Net Present Value (NPV), and Payback period (or Breakeven Point) for each strategy were determined to help recommend the best strategy. A qualitative survey was also conducted among doctors, nurses, and respiratory therapists who were taking care of patients hooked to ventilators to find out their experiences comparing hospital-owned and rental ventilators. Results: It was found that a total of 11 respirators were needed by the hospital to ensure that enough respirators were available for its patients at least 90% of the days in any month based on the previous four-year period. This meant acquiring three more ventilators as the hospital already owned eight. Among the strategies studied, projected over a 10-year period, the installment strategy (50% down payment with 0% interest over a 5-year period) proved to be the most financially advantageous with ROI = 9.36 times, IRR = 97% per year, MIRR = 26% per year, NPV = ₱39,324,297.60 and Payback period = 1.03 years). A more realistic installment strategy with 15% (paid quarterly or annually) and 25% annual interest rates were also explored with their financial parameters quite like but not as good as the 0% interest. The outright purchase of three ventilators came in lower (ROI = 4.53 times, IRR = 55% per year, MIRR = 19% per year, NPV = ₱38,064,297.60 and Payback period = 1.81 years) followed last by staggered purchase with ROI = 3.56 times, IRR = 64% per year, MIRR = 28% per year, NPV = ₱29,905,438.08, and payback period of 2.06 years. As there was no investment needed for the rental strategy, the only financial parameter available for it is the NPV which came out as ₱21,234,057.60. The qualitative part of the study showed that most of the healthcare workers involved in the care of patients attached to the ventilator were aware of the rental ventilators. The rental ventilators were generally described as of lower functionality and can more easily break down. The respondents almost uniformly expressed a preference for the hospital-owned ventilators. Conclusion This analysis showed that the best ventilator ownership strategy from a purely financial perspective for this hospital is by installment with a 50% down payment and 0% interest. Moderate rates of 15% and 25% interest per year were also good. These were followed by outright purchase and lastly by staggered purchase. The rental strategy gave the lowest cumulative 10-year income compared to any of the ownership strategies, but may still be considered good income because the hospital did not make any investment. However, it seems that most of the healthcare workers involved in taking care of patients on ventilators thought the rental ventilators were of lower quality and preferred the hospital-owned ventilators.

Background: Non-communicable diseases (NCDs) are among the growing public health problems globally which cause premature and preventable deaths. They remain as leading causes of mortality in the Philippines, specifically hypertension and Type 2 Diabetes Mellitus (T2DM). Objective: This study aimed to determine the factors associated with high risk for hypertension and T2DM among patients who were risk-assessed in the Center for Dialysis, Healthy Lifestyle, Ambulatory Surgery, Maternity Clinic and Newborn Care of Pasig City (CHAMP) Health Center from January to December 2020. Methodology: An analytical cross-sectional study design was utilized to determine the factors associated with hypertension and T2DM among risk-assessed patients. Secondary data from the NCD registry of the City Health Department of Pasig was obtained through a one-time collection. Results: Among the 77 patients included in the study, 19.48% were classified as high-risk for hypertension and T2DM. Through a simple logistic regression, no variable was statistically significant at a 5% level of significance which means there is no sufficient basis to conclude that there is an association between the factors with high risk for hypertension and T2DM. Looking at the characteristics of the participants, 74% were obese and more than half had no regular exercise; they may still be at risk for NCDs because being at non-high-risk does not eliminate risk completely. Conclusion Policies or strategies regarding access to health centers for risk assessment should not be neglected even during a communicable disease pandemic because this may lead to a misreporting of high-risk individuals.

Background and Objective: The focusing of resources to COVID-19 response hampered and disadvantaged primary care services including that for Non-Communicable Diseases (NCDs), compromising continuity of care and hence, patients’ disease status. However, studies from low- and middle-income countries (LMICs) remain sparse; therefore, evidence generation on how the pandemic impacted the provision of these primary care services in LMICs will help further understand how policies can be reframed, and programs be made more efficient and effective despite similar crises. To bridge this gap, the study investigated how the pandemic affected the implementation of NCD care at the primary care level in the Philippines. Methods: Thirty-one online focus group discussions via Zoom Meetings were conducted among 113 consenting physicians, nurses, midwives, and community health workers from various facilities — community health centers and stations, free-standing clinics, infirmaries, and level 1 hospitals — located within two provinces in the Philippines. All interviews were video-recorded upon participants’ consent and transcribed verbatim. Inductive thematic analysis was employed through NViVo 12® to generate themes, identify categories, and describe codes. Results: The impact of COVID-19 on NCD care at the primary care level revolved around heightened impediments to service delivery, alongside worsening of pre-existing challenges experienced by the healthcare workforce; subsequently compelling the public to resort to unhealthy practices. These detriments to the primary healthcare system involved resource constraints, discontinued programs, referral difficulties, infection, overburden among workers, and interrupted training activities. Citizens were also observed to adopt poor healthcare seeking behavior, thereby discontinuing treatment regimen. Conclusion Healthcare workers asserted that disadvantages caused by the pandemic in their NCD services at the primary care level possibly threaten patients’ health status. Besides the necessity to address such detriments, this also emphasizes the need for quantitative studies that will aid in drawing inferences and evaluating the effect of health crises like the pandemic on such services to bridge gaps in improving quality of care.

Objectives: To A functioning referral system is critical to the maternal health program, especially in the management of obstetric emergencies. This study explored supply-side barriers affecting the effective implementation of the said service delivery network (SDN) in Legazpi, Albay in the Bicol Region of the Philippines. Methods: Face-to-face in-depth interviews using semi-structured questionnaires were performed with health care providers involved in the SDN in Albay. Extensive note taking was done by the primary investigator while participants were observed during performance of duties from June - November 2018. Interviews were audio-recorded, transcribed, translated into English, and analyzed thematically along with the observation notes using NVivo. A deductive-dominant approach was utilized for the data content analysis. Results: Referral system barriers identified were cross-cutting across the different components of the health system such as governance, human health resource, service delivery and information systems. The barriers were further classified into individual, organizational and external-related factors in relation to the SDN. Examples of barriers included lack of knowledge of protocols and guidelines, lack of coordination between facilities, poor data management, inadequate capacity building opportunities, and constantly changing political landscape and policies. Conclusions The study is the first to explore barriers to effective service delivery network in maternal health in the country. Findings from the study provide significant insight to areas of improvement in the SDN that must be addressed to strengthen local health systems, especially with the country’s movement towards Universal Health Care where local health systems play a key role.

Background: Since 1976, Bicol Region had higher maternal mortality ratio (MMR) than the Philippine average and became the fourth region with the highest MMR in 2012. Looking at trends of maternal health outcomes and determining risk factors among mothers who died may guide interventions to reduce MMR. Objectives: To determine the changes in maternal mortality ratio (MMR) in the Bicol region from 2004 to 2017 and determine the sociodemographic profile of pregnant women who died from 2015 to 2018. Materials and Methods: A records review of Bicol?s Regional Field Health Services Information System from 2004 to 2017 and maternal death review reports from 2015 to 2018 was done. Changes in MMR was determined using Poisson regression. The sociodemographic characteristics and causes of maternal deaths were analyzed using frequencies and proportion. Results: From 2004 to 2017, MMR of 100.9 remained higher than the regional target of 31.6. Significant reductions in MMR were achieved in 2007 to 2008 and in 2011 to 2012 wherein MMR ranged between 75.3 to 89.3. However, by the end of 2012, maternal deaths again increased which reached 122.5 in 2017. From the maternal death reviews, it was observed that 29.5% of maternal deaths were aged 35 years and above and 7.5% were less than 20 years old. Mothers who had more than five pregnancies were 30.1% of total deaths. In terms of place of death, 15.7% died at home or in-transit to referral facilities. Hemorrhage or hypertension-related causes were the leading reasons for maternal deaths. Conclusion Significant reduction in MMR was not sustained after 2012 and higher deaths were reported in the succeeding years. Maternal deaths can be further reduced by using a systems approach, by promoting family planning, and by strengthening service delivery networks to effectively manage hemorrhage and hypertension-related emergencies.

Objectives: This research study aims to conduct a systematic review and critical appraisal of the quality of the existing peer-reviewed journal literature looking into the economic evaluation of control strategies used in parasitic diseases (i.e., STH and schistosomiasis).

Methods: Database searches were conducted in Embase, Science Direct, Medline, CINAHL, Econ Lit, and Academic Search Elite, by using search keywords or phrases. Using the predefined inclusion and exclusion criteria, a review of published online articles between January 1990 and December 2012 was conducted. Aside from the set of good practice guidelines in conducting economic evaluations, assessment of the quality of economic evaluations was also carried out following the Consolidated Health Economic Evaluation Reporting Standards (CHEERS) checklist.

Results: Given the inclusion and exclusion criteria set by this review, we systematically reviewed thirteen shortlisted samples of economic analysis studies. The current systematic review shows a wide variety of methodological approaches across studies, including differences in the type of economic evaluation, perspective, time horizon, approach, and adjustments for timing and certainty used.

Conclusions: In general, the economic evaluation studies that have been examined in this review have complied with the set of criteria of good practice in conducting an economic evaluation and that it can be considered helpful in making decisions and in understanding the economics of controlling these parasitic diseases.

Objectives: The availability of emergency obstetric and newborn care (EmONC) services is one of the key strategies in improving maternal health and achieving Sustainable Development Goal 3. Health staff knowledge and competency on these interventions are crucial to ensure the effective handling and management of obstetric and newborn emergencies. Health workers, despite having undergone formal training, require regular refresher courses to keep up with new, evidence-based information on EmONC intervention; and to ensure compliance with national and local referral guidelines. A two-day workshop was implemented to assess the knowledge and skills of health workers in Legazpi, Albay, regarding obstetric emergency cases and referral guidelines.

Methods: A pretest was conducted on the first day to assess the knowledge of the participants. A series of lectures were given before administering a posttest at the end of these lectures. An Objective Structured Clinical Examination (OSCE) was conducted on the second day, which aimed to assess the skills of the participants.

Results: The pretest findings indicated that the participants are generally knowledgeable about areas such as handwashing and prenatal care. Results of the posttest show that participants had difficulty with the category of referrals. Moreover, comparing the pretest and posttest scores, there is strong evidence that there is a difference in the median values of the pretest scores as compared to the posttest scores. The results of the OSCE also indicate the need for further training on partograph use and adherence to an EINC protocol. More than half of the participants passed all five parts of the OSCE.

Conclusion: The workshop contributed to an improvement in the knowledge of health care workers in obstetric emergency cases. Skills-wise, more frequent training may need to be conducted to improve other competencies such as partograph utilization and the practice of EINC interventions.

INTRODUCTION: Oral ivermectin is an approved first-line option to topical permethrin in Europe and Japan for the treatment of classic scabies, while combination oral ivermectin and topical permethrin is used in clinical practice for extensive or recurrent cases. There is unclear evidence on comparative efficacy and safety.

OBJECTIVES: To review the evidence on efficacy and safety of oral ivermectin versus topical permethrin or its combination in the treatment of classic scabies.

METHODS: We searched PubMed from January 1, 2016 up to August 7, 2021 for systematic reviews that included RCTs comparing oral ivermectin versus topical permethrin or its combination in the clinical treatment of scabies. We described the characteristics of included studies, assessed reporting quality, and summarized results and conclusion.

RESULTS: We included five systematic reviews. Permethrin did not differ from oral ivermectin in cure rate at the 3 to 6-week time point but had an earlier cure at 1-2 weeks. Adverse effects did not significantly diff er and were few, mild, and transient with both treatments. The evidence ranged widely from low to high certainty and mainly came from three moderate-to-high quality systematic reviews. Combination oral ivermectin and topical permethrin was ranked higher in efficacy but lower in safety compared to either drug alone in one moderate validity network meta-analysis.

CONCLUSION: There is varying certainty of evidence suggesting comparable efficacy and safety of oral ivermectin versus topical permethrin. Limited evidence suggest higher efficacy and lower safety of combination oral ivermectin and topical permethrin compared to either drug alone. An updated systematic review and network meta-analysis is warranted.
