BACKGROUND AND OBJECTIVES

The in vitro bioequivalence assessment using a dissolution apparatus, as specified by the United States Pharmacopeia (USP), is a critical parameter in the formulation and development of generic pharmaceutical products. This study is crucial for evaluating the interchangeability of generic drugs with their reference innovator counterparts. Post-market surveillance of generic drugs ensures consistent quality after distribution in the market. Metformin hydrochloride, a widely prescribed oral hypoglycemic agent for managing type 2 diabetes, is among the most utilized medications globally.

In the Philippines, there is a growing need to assess the bioequivalence of various generic formulations of metformin HCl f ilm coated tablets to ensure compliance with regulatory requirements. The Philippine Food and Drug Administration (FDA) mandates in vivo or in vitro bioequivalence including, dissolution profile comparison, as a prerequisite for the registration of generic drugs. This study aims to evaluate the quality and in vitro bioequivalence of metformin HCl f ilm-coated tablets available in the Philippine market by comparing their dissolution profiles against the innovator, Glucophage. This research seeks to provide insights into the interchangeability, therapeutic equivalence, and overall quality of these generic formulations, thus contributing to public health and regulatory standards.

METHODS

Generic metformin HCl film-coated tablets were subjected to quality control tests, including weight variation, thickness and diameter, hardness, friability, and disintegration tests, in accordance with USP guidelines. To assess in vitro bioequivalence, dissolution testing was performed, and the concentration of the dissolved drug was determined using a microplate assay reader to measure absorbance. Dissolution profiles of the generic metformin HCl film-coated tablets were compared to that of the innovator drug, Glucophage to evaluate bioequivalence.

RESULTS

All tested generic metformin HCl film-coated tablets complied with USP specifications for quality control tests, except for the hardness test, where three brands failed to meet the required standards. While for dissolution testing, five out of six generic brands demonstrated acceptable dissolution profiles and were bioequivalent to the innovator drug Glucophage. However, one brand (Brand A) failed to meet the bioequivalence criteria, exhibiting a dissolution profile outside the acceptable limits.

CONCLUSION

This study demonstrates that most generic metformin HCl film-coated tablets available in the Philippine market meet the United States Pharmacopeia (USP) quality control requirements and exhibit in vitro bioequivalence with the innovator drug. However, the failure of three brands to meet the hardness specifications and the lack of bioequivalence in one brand highlight the need for stringent quality assurance and  regulatory oversight. Ensuring compliance with these standards is critical to maintaining the safety, efficacy, and therapeutic interchangeability of generic drugs. These findings emphasize the importance of continuous post-market surveillance to uphold the quality of generic medications in the market, to safeguard public health.

OBJECTIVES

Clinical pathways (CPs) ensure adherence to heart failure (HF) management guidelines. To optimize quality care in a low resource setting, an evidence-based care pathway for the management of acute HF was implemented at the emergency department (ED) of the Philippine General Hospital (PGH), the designated national tertiary hospital and referral center. This study aimed to describe the characteristics of adults with acute HF admitted at the ED and evaluate the quality of care they received, measured using physician adherence to the hospital’s acute heart failure CP.

METHODS

This was a retrospective, descriptive cohort study. We reviewed the inpatient charts of all adult patients with acute HF admitted to the ED of the PGH and referred to the Division of Cardiovascular Medicine between December 1, 2022 and May 31, 2023. Quality of care was assessed based on adherence to quality indicators adapted from routine and conditional order sets detailed in the pathway. Descriptive statistics was utilized to describe patient characteristics, quality of care, and outcomes.

RESULTS

Two hundred thirty-six (236) patients were included, with a mean age of 51.8 years. Majority were male (53.4%); hypertension (61.4%) and ischemic heart disease (53.8%) were the most common comorbidities, and infection the most common precipitant of decompensation (60.6%). There were optimal adherence rates to routine orders, which included referrals to Internal Medicine and Cardiology, baseline vital signs monitoring, fluid intake and output monitoring, chest radiograph, complete blood count, blood urea nitrogen, sodium, potassium, prothrombin time, partial thromboplastin time, arterial blood gas, urinalysis, and N-terminal pro b-type natriuretic peptide. Conditional orders, such as oxygen support, focused echocardiography, thyroid - stimulating hormone, and the use of vasopressors, diuretics, and venous thromboembolism prophylactic agents, were optimally performed when warranted. However, we noted suboptimal adherence to certain resource-intensive conditional orders, such as hourly monitoring of urine output (61.4%), hooking to cardiac monitor (53.8%), and performance of 12-lead ECG within 10 minutes (56.8%). Further, only 43.9% of patients were referred to the intensive care unit. Troponin I, calcium, magnesium, and albumin were ordered in excess.

CONCLUSION

Overall adherence rate of physicians to the hospital’s Acute Heart Failure Pathway was satisfactory. Work is needed to improve adherence to hourly urine output monitoring, consistent hooking to cardiac monitor, and timely performance of 12-lead ECG – an effort that begins with expanding in-hospital diagnostic equipment and human resource supply. We recommend continuous pathway implementation with periodic evaluation and stakeholder feedback to further improve quality of care.

Introduction: Effective vaccination campaigns have been instrumental in reducing COVID-19 transmission and severe disease outcomes. Despite efforts to improve vaccine accessibility, vaccine literacy and confidence remain important determinants of vaccine uptake. Rural and geographically isolated communities often experience barriers to healthcare access that may affect vaccination coverage. This study aimed to assess COVID-19 vaccination coverage, vaccine literacy, and vaccine confidence among residents of selected Geographically Isolated and Disadvantaged Areas (GIDAs) in Floridablanca, Pampanga. Methods: A descriptive cross-sectional study was conducted among 211 residents of Barangays San Ramon and Nabuclod. Data were collected through face-to-face interviews using a translated and pretested questionnaire on vaccine literacy and vaccine confidence. Vaccination records obtained from the Rural Health Unit were reviewed to determine COVID-19 vaccination coverage. Descriptive statistics, including frequencies and percentages, were used to summarize the data. Results: The majority of respondents demonstrated an average level of vaccine literacy (75.8%), while 17.5% exhibited high vaccine literacy. Most respondents also demonstrated positive to very positive vaccine confidence (71.6%). Among the eligible population, 80.5% had completed the primary COVID-19 vaccination series, whereas 19.5% remained unvaccinated. Among those who completed the primary series, only 24.2% had received at least one booster dose. Conclusion Residents of the selected GIDAs generally demonstrated average vaccine literacy, positive vaccine confidence, and relatively high primary COVID-19 vaccination coverage. However, low booster uptake and the persistence of unvaccinated individuals highlight the need for sustained health education, improved healthcare accessibility, and targeted community-based interventions. These findings underscore the importance of strengthening vaccine literacy and confidence to support future immunization programs in geographically isolated communities.

BACKGROUND AND OBJECTIVE

Physician adherence to the recommended management of patients with heart failure with reduced ejection fraction (HFrEF) at the outpatient setting is crucial to reduce the burden of subsequent rehospitalization, morbidity, and mortality. Recently updated guidelines recommend early and rapid titration to optimal doses of medications in the first 2 to 6 weeks of discharge. In the absence of local data, our study evaluates physician adherence to guideline-recommended treatment in this setting.

METHODS

This is a retrospective cross-sectional study among post-discharge HFrEF patients at the outpatient department from December 2022 to May 2023 with a follow-up within three months. Clinical profile and treatment were extracted from medical records. Adherence to the 2021 ESC Guidelines Class I recommendations, among eligible patients, is measured as quality indicators. Data are presented using descriptive statistics.

RESULTS

A total of 99 patients were included in the study. Overall, adherence to prescription of beta-blockers (94.8%), ACEI/ARNI/ARBs (88.5%), and diuretics (100%) were high. Prescription of mineralocorticoid receptor antagonists (MRA) and sodium-glucose cotransporter-2 inhibitors (SGLT2i) were 67% and 57.3%, respectively. Over three months of follow-up, improvement in the quality of care was demonstrated with ACEI/ARNI/ARBs (81.8% to 90.9%), MRA (68.7 to 81.2%), and SGLT2i (58% to 67.7%). Beta-blocker use is consistently high at 97%. In the 3rd month post-discharge, titration to optimal doses was achieved in only 26.4%, 15%, and 6.25% for those on beta-blockers, ACEI/ARNI/ARB, and MRA, respectively. For non-pharmacologic management, referral to HF specialty was made in 30% and cardiac rehabilitation in 22.2%.

CONCLUSION

Among patients with HFrEF seen at the outpatient, there is good physician adherence to betablockers, ACEI/ARNI/ARBs, and diuretics. MRA and SGLT2i prescription, referral to HF specialty and cardiac rehabilitation, and up-titration to optimal doses of oral medications for HF need improvement. Hospital pathway development and regular performance evaluation will improve initiation, maintenance, and up-titration of appropriate treatment.

BACKGROUND AND OBJECTIVE

Contraceptives are widely acknowledged for preventing unwanted pregnancies. However, there is a prevalent lack of awareness regarding contraceptives, leading to unaddressed misconceptions. This study aimed to identify common contraceptive misconceptions among men and women of reproductive age and explore how primary health workers address them.

METHODS

A qualitative study was conducted in two phases within District 5, Manila City. Phase 1 comprised focused group discussions with men and women of reproductive age (n=60), while Phase 2 involved conducting in-depth interviews with primary healthcare providers (n=16). MAXQDA, a qualitative software, to organize and code the data, was utilized.

RESULTS

Women of reproductive age reported several misconceptions about contraceptives, including concerns about adverse health effects, emotional and behavioral changes, perceived ineffectiveness, and cosmetic or bodily changes. For instance, they believed that contraceptives could lead to serious health complications, such as cancer, genital injury, and even death. Primary healthcare providers addressed these misconceptions through open dialogue during service delivery, particularly during prenatal and postpartum check-ups and infant immunizations. They utilized patient education strategies, including the teach-back method, and conducted community outreach and workshops on contraceptives and family planning, especially during Women’s Month.

CONCLUSION

Several misconceptions were identified among women of reproductive age regarding the proper use and safety of contraceptive methods, as well as misguided beliefs. In contrast, men did not exhibit any misconceptions about contraceptives, which warrants further investigation. Primary healthcare providers have taken a proactive approach to address this issue by offering comprehensive explanations and ensuring clear understanding between healthcare providers and women. Promoting contraceptive health literacy could help bridge the knowledge gap between men and women of reproductive age.

BACKGROUND AND OBJECTIVE

Long-term treatment of people living with HIV (PLHIV) encounters various challenges, such as medication adherence, stigma, discrimination, and healthcare access. Patient satisfaction with healthcare services is vital for maintaining treatment adherence. Therefore, understanding the factors influencing patient satisfaction is crucial. We conducted a qualitative study to explore these factors in primary HIV care facilities in Metro Manila, Philippines.

METHODS

In this qualitative study, we interviewed PLHIV aged 18-59 receiving antiretroviral therapy (ART) in primary HIV care facilities in Metro Manila. Data saturation was reached after 19 in-depth interviews. We transcribed all audio files verbatim in Filipino and analyzed the data using deductive and inductive thematic analysis, guided by the SERVQUAL model as a theoretical framework. We employed MAXQDA, a qualitative data analysis software for coding and data management. We illustrated themes and sub-themes with quotes derived from the data.

RESULTS

Six key themes emerged regarding factors influencing patient satisfaction: tangibles, reliability, responsiveness, assurance, empathy, and location. The first five themes aligned with the SERVQUAL model, while location emerged as a new theme. PLHIV preferred accessible clinics, a clean and pleasant ambiance, and positive interactions with healthcare providers. Moreover, they suggested facility improvements, including expansion, better ventilation, enhanced service delivery, and increased healthcare staff.

CONCLUSION

Enhanced service delivery and positive healthcare interactions, along with favorable physical attributes of primary HIV care facilities, drive patient satisfaction and long-term retention. These modifiable factors contribute to the continuous care of PLHIV, ultimately improving their quality of life.

BACKGROUND AND OBJECTIVE

COVID-19 contributes significantly to global morbidity and mortality. Age-related comorbidities elevate the risk of severe cases. Studies have recently demonstrated that widely available medications, including tocilizumab (TCZ), can manage severe symptoms. However, its effectiveness is unclear, particularly among the older population. Therefore, this review aimed to evaluate TCZ’s efficacy in managing severe pneumonia in individuals aged 50 and older.

METHODS

We systematically search several databases and gray literature including Web of Science, CINAHL, Academic Search Complete, PsycINFO, PsycArticles, SocINDEX, CENTRAL/Cochrane Library, PubMed/MEDLINE for original research articles in English across several study designs published in the year 2020-2022. A narrative synthesis was conducted to summarize the evidence. We employed the NIH quality assessment tool for observational cohort studies to evaluate risk of bias. Additionally, we utilized GRADE to appraise the certainty of evidence.

RESULTS

Among 539 screened articles, only five studies met the selection criteria. Tocilizumab's impact on severe COVID-19 pneumonia revealed a diverse effect on mortality rate, with 29% in the TCZ group, and 40% in the controls died within 30 days of intubation (OR 0.61; 95% CI, 0.27-1.36). It is also reported that TCZ was not associated with mortality, despite faster decline in pulmonary function and prolonged fever. Hospital mortality in the TCZ group was significantly lower than in the controls, and age over 60 was the only significant risk factor. Moreover, administering TCZ reduced mechanical ventilation needs, with 82% extubated compared to 53% in controls. However, 45% in TCZ group was associated with a higher ventilator-associated pneumonia rate than in the untreated group which was 20% (P CONCLUSIONS

The effects of tocilizumab on reducing mortality risk and improving the survival rate of COVID-19 patients with pneumonia remained inconclusive. Yet, the majority of results suggested that giving tocilizumab leads to shorter hospital stays, lowers the requirement for mechanical ventilation, and decreases the likelihood of ICU transfer. Tocilizumab is linked to the incidence of secondary infections; hence, this medication should be closely monitored for side effects.
