Diabetes Care in the Philippines

Pituitary Adenoma in the Philippines: A Scoping Review on the Treatment Gaps, Challenges, and Current State of Care

BACKGROUND

Pituitary adenomas are benign brain tumors that impose a heavy burden on patients worldwide. The local burden of disease is yet to be established due to scarcity of data. In line with this, this study aims to present the challenges and gaps in the treatment of pituitary adenomas in the Philippines.

METHODS

A scoping review of available relevant literature on epidemiology, clinical experience with treatment, health financing, and healthcare delivery system based on the Preferred Reporting Items for Systematic reviews and Meta-analysis guidelines extension for Scoping Reviews was conducted.

RESULTS

The scarcity of updated local clinical data, inequity of distribution of resources, inadequate government support, and lack of affordable diagnostic testing, medications, and neurosurgical procedures are the factors that hinder provision of adequate care of pituitary adenomas in the Philippines.

CONCLUSION

There are notable treatment gaps in the management of pituitary adenomas in the Philippines, which may be addressed by strengthening universal healthcare. Strategies to address these gaps were proposed, including improving public-private insurance coverage, increasing manpower, enhancing accessibility to resources, and spreading more awareness.

Current status of diabetes mellitus care and management in the Philippines

AIMS

In this paper, we discuss the existing data on the burden of diabetes in the Philippines and present the status of management, prevention, and control of diabetes in the country.

METHODS

A review of literature was conducted to synthesize the status of diabetes mellitus in the Philippines.

RESULTS

An estimated 4.3 million Filipinos were diagnosed with diabetes, while 2.8 million remained undiagnosed in 2021. Diabetic retinopathy is a top cause of preventable blindness in Region 3, Philippines. Diabetic nephropathy contributes to 38% of renal disease cases in the Philippines. The 2021 Philippine Guidelines on Periodic Health Examination (PhEX) advocate for the utilization of fasting blood sugar (FBS) as a screening measure for Type 2 Diabetes Mellitus (T2DM) in healthy adults aged 40 years and older or in those with specified risk factors. The alternative option of hemoglobin A1c is (HbA1c) deemed appropriate but comes with a conditional recommendation due to its uneven accessibility across different regions of the country. Treatment guidelines align between the Philippines and the US. Initial medical nutrition therapy involves healthy habits, progressing to pharmacologic treatment if necessary. Financial constraints, seen in limited insurance coverage and high out-of-pocket costs, impede care, amplifying disease impact. The complex diabetes care, encompassing pharmacotherapy, nutrition, exercise, and monitoring, faced challenges during COVID-19 quarantines.

CONCLUSION

In conclusion, the paper outlines diabetes care principles-screening, diagnostics, and multidisciplinary care-alongside economic implications. Local and national initiatives are discussed to mitigate diabetes trends and reduce its burden in the Philippines.

Costs incurred by people with co-morbid tuberculosis and diabetes and their households in the Philippines

OBJECTIVE

Diabetes is a risk factor for TB mortality and relapse. The Philippines has a high TB incidence with co-morbid diabetes. This study assessed the pre- and post-TB diagnosis costs incurred by people with TB and diabetes (TB-DM) and their households in the Philippines.

METHODS

Longitudinal data was collected for costs, income, and coping mechanisms of TB-affected households in Negros Occidental and Cebu, the Philippines. Data collection was conducted four times during TB treatment. The data collection tools were developed by adapting WHO's cross-sectional questionnaire in the Tuberculosis Patient Cost Surveys: A Handbook into a longitudinal study design. Demographic and clinical characteristics, self-reported household income, number of facility visits, patient costs, the proportion of TB-affected households facing catastrophic costs due to TB (>20% of annual household income before TB), coping mechanisms, and social support received were compared by diabetes status at the time of TB diagnosis.

RESULTS

530 people with TB were enrolled in this study, and 144 (27.2%) had TB-DM based on diabetes testing at the time of TB diagnosis. 75.4% of people with TB-DM were more than 45 years old compared to 50.3% of people with TB-only (p<0.001). People with TB-DM had more frequent visits for TB treatment (120 vs 87 visits, p = 0.054) as well as for total visits for TB-DM treatment (129 vs 88 visits, p = 0.010) compared to those with TB-only. There was no significant difference in the proportion of TB-affected households facing catastrophic costs between those with TB-DM (76.3%) and those with TB-only (68.7%, p = 0.691).

CONCLUSION

People with TB-DM in the Philippines face extensive health service use. However, this does not translate into substantial differences in the incidence of catastrophic cost. Further study is required to understand the incidence of catastrophic costs due to diabetes-only in the Philippines.

Patient education for people living with diabetes in the Philippines: A scoping review of information needs, diabetes knowledge and effectiveness of educational interventions

BACKGROUND AND AIMS

Despite the growing burden of diabetes in the Philippines, available evidence indicates that its care and control are far from optimal, including patient education. The aim of this scoping review was to synthesize information in the available literature to describe the state of science of patient education for people living with diabetes in the Philippines, specific to educational needs, diabetes knowledge, and effectiveness of educational interventions.

METHODS

Medline, Embase, Emcare, CINAHL, Pubmed and American Psychological Association PsycInfo were searched from data inception through July 2021. Studies of any methodology (qualitative/quantitative/mixed methods), sample size, and language were eligible for inclusion.

RESULTS

Of 2021 initial citations, 7 studies were included, with all being quantitative in design and with a median Critical Appraisal Skills Program score of 8/12. Information needs were described by one study and related to self-care abilities. Diabetes knowledge was measured in 6 studies and improved significantly after educational interventions. Overall, studies showed that educational interventions significantly impacted self-efficacy, anthropometric measures, hemoglobin A1c levels, utilization of care and routine programme and attitudes regarding their health.

CONCLUSIONS

The findings highlight the importance of a comprehensive and culturally appropriate educational intervention for this population. Further research is needed to develop such intervention and assess its effectiveness to change behaviour, such as increasing physical activity.

Factors Associated with Regular Zumba Practice as Preliminary Results: A Population-Based Approach in Cebu Province, the Philippines

The prevalence of overweight/obesity in the adult population in the Philippines has doubled in the past 20 years. Zumba exercise has recently been implemented throughout the Philippines. However, there is scarce information on the effects of Zumba on obesity and Zumba participants’ characteristics in the Philippines. This study described the current practice of Zumba in the Philippines, along with the practitioners’ characteristics, and identified factors associated with Zumba participation. In this observational, cross-sectional study, a structured questionnaire was used to survey 10 Zumba locations in September 2019. Anthropometric measurements of participants were assessed. Respondents included 171 women (88.6%) and 22 men (11.4%), with a mean (±standard deviation [SD]) age of 44.1 (±8.9) years. All respondents answered that Zumba was enjoyable, and some answered “very enjoyable”. Determinants of frequent participation were as follows: being older than the mean age of participants, starting Zumba to enjoy dancing, starting Zumba not to lose weight, shopping mall location, and participation fee required. “To enjoy dance” being a motivation for Zumba practice was identified as a determinant of frequent participation rather than “to lose weight.” The element of “enjoyable” may strongly influence the continuation and frequent participation of Zumba exercise in the Philippines.

Examining community-managed drug outlets' failure in geographically isolated and disadvantaged areas: insights from the consumers' end

Objectives

The article aimed to examine the impact of poor purchasing power, perceptions on the physical structure, and medicine demand to community-managed drug outlets or Botika ng Barangay (BnB) in the Philippines. The study investigated what contributes to program resiliency or failure in so far as the consumers in geographically isolated and disadvantaged area (GIDA) are concerned.

Methods

Findings were drawn from five sets of focus-group discussion (FGD) among residents, four in-depth interviews (IDIs) with former operators of BnB and three IDI with former members of the village council specifically assigned in health sector.

Key findings

The study found out that all our study variables namely; poor purchasing power, perceptions on BnBs' physical image, and limited medicines that do not match the consumers' medicine demand did not contribute to the failure of the program in their communities. However, the study found out that informal arrangements in the community which allowed people to just loan medicines without actually paying in return was intimately connected to BnBs' closure in the communities.

Conclusion

The study suggests that, in the context of GIDAs, the failure of community-managed drug outlets rests as well on financially unsustainable practices in the community. This, we believe, can be negated through provisions for medicine subsidy.

Governance Functions to Accelerate Progress toward Universal Health Coverage (UHC) in the Asia-Pacific Region

Many countries in the Asia-Pacific region have committed to universal health coverage (UHC), which is reflected in both their political commitment and the governance actions they have taken in steering their health systems toward the goals of universal access to care and protection from financial hardship. Countries throughout the region are at different stages of development and have different political and governance contexts, which in turn shape how they pursue governance for UHC. This article reviews the governance functions deployed in the Asia-Pacific and finds that, in many, governance reforms adapting their health systems toward greater regulation, accountability, oversight, and stewardship of the health system have been part of their wider move toward UHC. Countries have not followed a set pattern, but shared aspects include establishing UHC as a goal in national policy making and priority setting; the creation of new roles and/or new institutions within the health system; establishing systems of monitoring and evaluation; and putting in place mechanisms to facilitate collaboration and ensure greater accountability. The relationship between governance and UHC in the Asia-Pacific region is found to be complex, negotiated, and shaped by a number of factors in both the internal and external environment, including broader governance arrangements in the public sector (institutional changes and decentralization are particularly prominent factors) and the ability of governments to implement policies and steer the health system.

Insulin Resistance and β-Cell Function of Lean versus Overweight or Obese Filipino Patients with Newly Diagnosed Type 2 Diabetes Mellitus

Objectives

To compare the level of insulin resistance and β-cell function between lean and overweight/obese Filipino patients with newly diagnosed type 2 diabetes mellitus (T2DM).

Methodology

This was a cross-sectional analytical study including newly diagnosed T2DM Filipino patients from St. Luke’s Medical Center - Quezon City. The patients were classified as either lean or overweight/obese. Age, sex, smoking history, anthropometric measures and blood pressure were obtained. Insulin resistance and β-cell function were determined using the homeostasis model assessment (HOMA). The original model (HOMA1) and the updated model (HOMA2) were used.

Results

A total of 80 subjects were included. There were 40 subjects in each group. The overweight/obese subjects had significantly higher mean insulin resistance (HOMA1-IR 9.8±11.7, HOMA2-IR 3.0±2.0) compared to the lean group (HOMA1-IR 2.9±1.5, HOMA2-IR 1.3±0.5). This was consistent in both HOMA1 and HOMA2 (p-values=0.001 and <0.001, respectively). The mean β-cell function of the overweight/obese patients was significantly higher than the lean subjects when using HOMA1 (lean=57.8±35.5, overweight/obese=93.6±66.4, p-value=0.003), but not in HOMA2 (lean=57.6±30.5, overweight/obese=74.8±45.7, p-value=0.051). Overweight/obesity increased HOMA1-IR by 4.0 and HOMA1-B by 46.1 (p-values= 0.002 and <0.001, respectively). Through the use of HOMA2, overweight/obesity increased HOMA2-IR by 1.4 and HOMA2-B by 29.1 (p-values<0.001). Being overweight/obese was also associated with significantly higher odds for developing greater insulin resistance (HOMA1-IR adjOR = 5.6, 95%CI= 1.7-19.2, p-value=0.005; HOMA2-IR adjOR=10.9, 95%CI=3.4-34.9, p-value<0.001) and lower odds for a decreased β-cell function (HOMA1-B adjOR = 0.2, 95%CI = 0.05-0.9, p-value=0.033; HOMA2-B adjOR=0.2, 95%CI=0.04-0.9, p-value=0.043) compared to being lean.

Conclusion

Newly diagnosed overweight/obese T2DM had higher mean insulin resistance and β-cell function compared to lean T2DM. Overweight/obesity was also associated with higher odds of developing insulin resistance and lower odds for a decreased β-cell function compared to being lean. The overweight/obese T2DM group also had worse metabolic profile manifested by higher FPG, HbA1c, SGPT and blood pressures compared to the lean T2DM group.

A Conceptual Model for Quality of Life Among People with Type 2 Diabetes in the Philippines

Background

The increased prevalence of chronic diseases is a social issue in developing countries.

Methods

To create a conceptual model representing the quality of life of low-income people with type 2 diabetes in the Philippines, 117 low-income adult participants in a public support group were studied, and the Physical Component Summary (PCS) and Mental Component Summary (MCS) scores on quality of life (QOL) were analyzed in terms of their relationships with the following factors: basic attributes, physical factors (glycated hemoglobin level, complications, comorbidities, and symptoms), social factors (support, education, and financial status), and cognitive factors (knowledge, attitude, self-efficacy, and self-management behavior).

Results

Based on correlation coefficients among variables and goodness-of-fit test results through a path analysis, 2 models representing causal relationships were created, both of which showed sufficient goodness-of-fit.

Conclusion

Glycated hemoglobin levels, knowledge of blood glucose levels, self-efficacy, and self-management behavior (exercise) influenced PCS scores, while age, glycated hemoglobin levels, neuropathy, knowledge of insulin, self-efficacy, and self-management behavior (exercise) influenced MCS scores. The influence of self-efficacy was prominent in both cases, providing an important insight for healthcare professionals to develop effective support methods.

Developing and testing a model of quality of life among chronically-ill, community-dwelling older adults: A structural equation model

PURPOSE

Although healthy ageing aims for better quality of life, the inability of older adults to adequately care for themselves and their health impair the realization of such objective. Moreover, in a collectivist community like the Philippines, the family, community, and Transcendent are inseparable in promoting quality of life. This study developed and tested a model of quality of life (QoL) among chronically-ill, community-dwelling older adults.

MATERIALS AND METHODS

From August to November 2017, a cross-sectional study of 304 chronically-ill, community-dwelling older adults from selected rural communities in the Philippines was conducted. Respondents completed a five-part survey packet composed of the socio-demographic profile, modified Older People's Quality of Life, Spirituality Assessment Scale, Hypertension Self-Care Profile, and Diabetes Self-Management Questionnaire.

RESULTS

Socio-demographics, community satisfaction, spirituality, and disease self-management accounted 29.00% of QoL, generating a good model (χ²/df = 1.44, RMSEA = 0.038, and PNFI = 0.64). Spirituality (β = 0.34, p < 0.01) was the strongest predictor of QoL, while community satisfaction had both direct (β = 0.26, p < 0.01) and indirect (β = 0.08, p < 0.01) effects. Disease self-management directly (β = 0.15, p = 0.016) influenced QoL. In contrast, longer chronicity and larger family size impair QoL.

CONCLUSION

Quality of life among chronically-ill, community-dwelling older adults is a multi-faceted health construct influenced by socio-demographics, disease self-management, community satisfaction, and spirituality. The presented model highlights the positive effect of disease self-management, community satisfaction, and spirituality which can be utilized in developing appropriate community-based geriatric strategies, policies, and programs. Further, forming collaborative groups with socially-active community elderly and community-based self-care programs can be ventured to address the needs of older adults.

How Does Ambient Air Temperature Affect Diabetes Mortality in Tropical Cities?

Diabetes is well-known as one of the many chronic diseases that affect different age groups. Currently, most studies that evaluated the effects of temperature on diabetes mortality focused on temperate and subtropical settings, but no study has been conducted to assess the relationship in a tropical setting. We conducted the first multi-city study carried out in tropical cities, which evaluated the temperature–diabetes relationship. We collected daily diabetes mortality (ICD E10–E14) of four Philippine cities from 2006 to 2011. Same period meteorological data were obtained from the National Oceanic and Atmospheric Administration. We used a generalized additive model coupled with a distributed lag non-linear model (DLNM) in determining the relative risks. Results showed that both low and high temperatures pose greater risks among diabetics. Likewise, the study was able to observe the: (1) high risk brought about by low temperature, aside from the largely observed high risks by high temperature; and (2) protective effects in low temperature percentile. These results provide significant policy implications with strategies related to diabetes risk groups in relation to health service and care strategies.

Transcultural Endocrinology: Adapting Type-2 Diabetes Guidelines on a Global Scale

Type-2 diabetes (T2D) needs to be prevented and treated effectively to reduce its burden and consequences. White papers, such as evidence-based clinical practice guidelines (CPG) and their more portable versions, clinical practice algorithms and clinical checklists, may improve clinical decision-making and diabetes outcomes. However, CPG are underused and poorly validated. Protocols that translate and implement these CPG are needed. This review presents the global dimension of T2D, details the importance of white papers in the transculturalization process, compares relevant international CPG, analyzes cultural variables, and summarizes translation strategies that can improve care. Specific protocols and algorithmic tools are provided.
