BACKGROUND

Community Health Workers (CHWs) play a vital role in addressing community healthcare needs, yet little is known about their psychosocial status and job satisfaction. This study aimed to describe the psychosocial status and job satisfaction of CHWs, and examine the factors associated with their job satisfaction.

A cross-sectional study was conducted among 440 CHWs aged 25-60 years working in urban and rural areas of Batangas, Philippines. Linear regression models were used to examine the association between psychosocial factors and job satisfaction. Other factors associated with job satisfaction were also examined.

Despite 90.0% of CHWs reporting high perceived stress and 52.1% experiencing high depressive symptoms, they demonstrated relatively high job satisfaction (mean [standard deviation]= 80.05 [17.56]; range= 0-100) and high perceived social support (mean [standard deviation]= 25.09 [2.93]; range= 10-30). Among psychosocial factors, only perceived social support was associated with job satisfaction (unstandardized beta [B] 0.93; 95% confidence interval [CI] 0.44, 1.41). Other factors associated with job satisfaction include fixed working hours (B 4.71; 95% CI 0.49, 8.94), work amenities (B 7.37; 95% Cl 0.03, 14.72), ≥21 years of work experience (B 5.64; 95% CI 0.35, 10.93), and working in rural areas (B 5.88; 95% CI 2.77, 8.99).

Psychological factors such as perceived stress and depressive symptoms were not found to be associated with job satisfaction among CHWs. However, factors such as greater perceived social support, fixed working hours, work amenities, longer work experience, and working in rural areas were identified as contributors to higher levels of job satisfaction among CHWs.

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.

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.

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.

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

Long-term treatment and medication compliance are critical for managing conditions like hypertension, yet only 20% of cases are well-controlled, mainly due to socioeconomic factors. The Expanded Senior Citizens Act of 2010 offers a 20% discount on medications to improve compliance, but many seniors need to be made aware of these benefits. Evaluating satisfaction with the Act, specifically regarding its medication-related provisions, is essential for enhancing compliance and health outcomes among senior citizens.

This study examined the association between satisfaction with the medication provisions of the Senior Citizens Act, the frequency of senior identification card usage, and medication compliance among hypertensive patients.

We conducted a community-based cross-sectional study with 458 hypertensive senior citizens in Dasmariñas City, Cavite, Philippines. Senior citizens were randomly selected and completed a survey using a validated, self-developed questionnaire and the Hill-Bone High Blood Pressure (HB-HBP) compliance scale. We performed linear regression analysis to examine the association between their satisfaction and the use of senior citizens’ benefits on their medication compliance.

Senior citizens were 60-88 years old (mean 69; standard deviation [SD] 5.9). Thirty-eight percent were satisfied with the Senior Citizens Act and 49% regularly used their senior citizen card. Senior citizens scored an average of 46.82 (SD 4.96) on the HB-HBP compliance scale (possible range = 14-56), indicating high compliance. Those dissatisfied with the Senior Citizens Act were less compliant with their antihypertensive medications [B (unstandardized beta) = -1.65, 95% CI (Confidence Interval) = -2.70, -0.61]. Similarly, those who rarely or never used their senior identification cards (B = -1.54, 95% CI = -2.61, -0.48) and those who used them occasionally (B = -1.43, 95% CI = -2.57, -0.29) showed lower medication compliance compared to those who used them regularly.

Senior citizens who are satisfied with the medication provisions of the Act and regularly use their senior identification cards exhibit higher compliance with their antihypertensive medications than those with lower satisfaction and infrequent card usage. Interventions should prioritize educational sessions to inform senior citizens about the benefits of the Senior Citizens Act, including how to use their identification cards to access medication discounts effectively.

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.

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.

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.

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 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.

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.

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.

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.

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.

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.

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.
