Facing the digital frontier: exploring user acceptance of electronic health records in an urban, rural and remote setting in the Philippines.

OBJECTIVES: A thorough understanding of user needs and behavioural intent-to-use underpins the development of a responsive health information system. This study aimed to examine health workers' intent-to-use an electronic health record (EHR) system in an urban, rural and remote setting in the Philippines. METHODS: Following the Unified Theory of Acceptance and Use of Technology framework, user acceptance and the factors influencing intent-to-use the EHR were examined through a self-administered questionnaire. A total of 128 EHR users, comprising physicians, nurses, midwives, barangay health workers and administrative staff, were surveyed. Median scores for each domain were compared across the sites using the Kruskal-Wallis test. Ridge regression analysis was used to identify factors associated with behavioural intent-to-use. RESULTS: Over 94% of users across all sites reported their intent-to-use the EHR in the near future. Of the seven predictor variables examined, only self-efficacy was found to be significantly associated with behavioural intent-to-use. Intent-to-use the EHR increased by 31% (p=0.007) for each unit increase in self-efficacy score among participants. DISCUSSION: Acceptance was high across the three sites, with self-efficacy being a predictor of intent-to-use the technology. This suggests that users are more likely to adopt an EHR if they believe they have the capacity to successfully navigate the technology and perform their designated tasks with it. CONCLUSION: Co-producing interventions with primary care providers is crucial in sustaining EHR systems. Rather than developing a technology based on the surveillance needs of policymakers, an EHR developed from the grassroots was shown to be well-received by end-users.

Promoting equitable and patient-centred care: an analysis of patient satisfaction in urban, rural and remote primary care sites in the Philippines.

OBJECTIVES: This study measured changes in patient satisfaction levels before and after the introduction of primary care system strengthening interventions in urban, rural, and remote sites in the Philippines. METHODS: A previously validated 16-item questionnaire was distributed to 200 patients per site before implementation of interventions and to a different set of 200 patients 1 year after implementation. We compared the percentage change in highly satisfied patients per site before and after implementing interventions using a two-proportion Z-test. RESULTS: The urban site had a significant increase in patient satisfaction in 13 survey items, which corresponded to the domains of healthcare availability, service efficiency, technical competency and health communication. The rural site had a significant increase in six survey items, which corresponded to the domains of service efficiency, environment, location, health communication and handling. The remote site had a decrease in patient satisfaction in 10 survey items, with a significant increase in only 4 items under the domains of healthcare availability and handling. CONCLUSION: Our findings support the 'inverse equity hypothesis', where well-resourced urban communities quickly adopt complex health interventions while rural and remote settings experience delays in effectively meeting patient needs and system demands. Extended intervention periods and targeted strategies may be necessary to impact patient satisfaction in underserved areas considerably.

Feasibility, acceptability and impact of a clinical decision support tool among primary care providers in an urban, rural and remote site in the Philippines.

INTRODUCTION: Strengthening primary care helps address health inequities that continue to persist in the Philippines. The Philippine Primary Care Studies pilot-tested interventions to improve the primary care system. One intervention was the provision of a free subscription to an electronic decision support application called UpToDate (UTD) for primary care providers (PCPs), including doctors, nurses, midwives and community health workers (CHWs). This study aimed to (1) assess the feasibility of using UTD as information source for PCPs in urban, rural and remote settings, (2) determine the acceptability of UTD as an information source for PCPs and (3) examine the impact of UTD access on PCP clinical decision-making. METHODS: Four focus group discussions (FGDs) and two key informant interviews (KII) were conducted to gather insights from 30 PCPs. Thematic analysis through coding in NVivo V.12 was done using the technology acceptance model (TAM) as a guiding framework. RESULTS: All PCPs had positive feedback regarding UTD use because of its comprehensiveness, accessibility, mobility and general design. The participants relayed UTD's benefit for point-of-contact use, capacity-building and continuing professional development. PCPs across the three sites, including CHWs with no formal medical education, were able to provide evidence-based medical advice to patients through UTD. However, external factors in these settings impeded the full integration of UTD in the PCPs' workflow, including poor internet access, unstable sources of electricity, lack of compatible mobile devices and the need for translation to the local language. CONCLUSION: UTD was a feasible and acceptable clinical decision support tool for the PCPs. Factors affecting the feasibility of using UTD include technological and environmental factors (ie, internet access and the lack of translation to the local language), as well as the organisational structure of the primary care facility which determines the roles of the PCPs. Despite the difference in roles and responsibilities of the PCPs, UTD positively impacted decision-making and patient education for all PCPs through its use as a point-of-contact tool and a tool for capacity-building.

Reinfection rates, change in antibody titers and adverse events after COVID-19 vaccination among patients previously infected with COVID-19 in Metro Manila, Philippines: a secondary analysis of a completed cohort study.

BACKGROUND: Variation in immune response to COVID-19 vaccines is observed among different ethnicities. We aimed to describe the reinfection rates, change in antibody titers, and adverse events among Filipinos. METHODS: This is a secondary analysis of a cohort study of 307 participants within one year of having COVID-19 infection. We measured COVID-19 antibody levels at pre-determined timepoints (Days 21, 90, 180, 270, and 360 from initial infection). We monitored for COVID-19 symptoms and obtained details on COVID-19 vaccination. An adjudication committee classified the participants as probable, possible, or unlikely COVID-19 reinfection. We determined the probable reinfection rate, adverse events, and the geometric mean titer (GMT) ratio of pre- and post-vaccination antibody levels according to type and brand of COVID-19 vaccine. RESULTS: At the end of the follow-up period, 287 (93.5%) out of 307 study participants were fully vaccinated, 1 was partially vaccinated (0.3%), and 19 were unvaccinated (6.2%). Among the fully vaccinated participants, those given mRNA vaccines had the lowest reinfection rate (19.2 cases/100 person-years, 95% CI 9.6, 38.4), followed by viral vector vaccines (29.8 cases/100 person-years, 95% CI 16.9, 52.4). We observed the highest reinfection rate among those given inactivated virus vaccines (32.7 cases/100 person-years, 95% CI 23.6, 45.3). The reinfection rate was 8.6 cases/100 person-years (95% CI 4.1, 17.9) for unvaccinated participants and 3.6 cases/100 person-years (95% CI 0.5, 25.3) for partially vaccinated participants. We observed the largest rise in antibody titers among those given mRNA vaccines (GMT ratio 288.5), and the smallest rise among those given inactivated virus vaccines (GMT ratio 16.7). We observed the highest percentage of adverse events following immunization with viral vector vaccines (63.8%), followed by mRNA vaccines (62.7%), and the lowest for inactivated virus vaccines (34.7%). No serious adverse events were reported. CONCLUSION: Vaccinees given the mRNA vaccines had the lowest reinfection rate and the highest rise in antibody titers. Vaccinees given inactivated virus vaccines had the highest reinfection rate, smallest rise in antibody titers, and lowest percentage of adverse events. The small sample size and imbalanced distribution of the type of vaccines received limits the external generalizability of our results. STUDY REGISTRATION: The cohort study was registered at the Philippine Health Research Registry on December 14, 2020 (PHRR201214-003199).

Next-Gen biotherapeutics: A systematic review and network meta-analysis on postbiotics as treatment for pediatric atopic dermatitis.

BACKGROUND: Due to the recency of the postbiotic field, no head-to-head postbiotic studies have investigated its biotherapeutic potential for atopic dermatitis (AD). No network meta-analysis (NMA) has been conducted to synthesize relevant studies comparing postbiotic interventions for AD. OBJECTIVE: To assess the comparative efficacy and safety of postbiotic strains in the treatment of pediatric AD. METHODOLOGY: This was an NMA of randomized controlled studies that evaluated postbiotics in treating pediatric AD. Systematic search of databases and registers from inception to November 30, 2022. Three authors independently performed the search, screening, and appraisal using the Cochrane risk-of-bias tool version 2 and data extraction. Data analysis was performed using STATA14 software. RESULTS: Nine studies evaluated eight postbiotic preparations. Lactobacillus rhamnosus IDCC 3201 (LR) ranked highest in the efficacy outcome. Compared to placebo, LR may be effective in reducing symptoms of atopic dermatitis in the main analysis (SMD -0.53, 95%CI -1.02 to -0.04) and sensitivity analysis involving studies that used SCORAD (MD -5.52, 95% CI -10.46 to -0.58), based on low-certainty evidence. Based on moderate-certainty evidence, LR probably did not increase the risk of adverse events (RR 0.97, 95% CI 0.79, 1.21). Although Lactobacillus paracasei GM080 (LP2) ranked highest in the safety outcome, it may not reduce AD symptoms compared to placebo (SMD -0.03, 95% CI -0.37, 0.32) based on low-certainty evidence. CONCLUSION: LR showed significant benefits in children with AD based on low-certainty evidence. Further investigation of LR is recommended.

Durability and extent of protection of SARS-CoV-2 antibodies among patients with COVID-19 in Metro Manila, Philippines.

Introduction: Information on the magnitude and durability of humoral immunity against COVID-19 among specific populations can guide policies on vaccination, return from isolation and physical distancing measures. The study determined the durability of SARS-CoV-2 antibodies after an initial infection among Filipinos in Metro Manila, Philippines, and the extent of protection SARS-CoV-2 antibodies confer against reinfection. Methods: We conducted a cohort study to monitor the antibody levels of patients diagnosed with COVID-19. Receptor-binding domain (RBD)-specific antibodies were measured at Days 21, 90, 180, 270 and 360. Antibody levels were reported as geometric mean titers (GMT) with geometric standard deviation (GSD). Differences in GMT were tested using Friedman test and Kruskal Wallis test, with Bonferroni multiple comparisons procedure. Adjusted hazard ratios on the development of probable reinfection were estimated using Cox proportional models. Results: There were 307 study participants included in the study, with 13 dropouts. Study participants received SARS-CoV-2 vaccines at varying times, with 278 participants (90.5%) fully vaccinated by the end of study. The GMT of the study cohort increased over time, from 19.7 U/mL (GSD 11) at Day 21; to 284.5 U/mL (GSD 9.6) at Day 90; 1,061 U/mL (GSD 5.3) at Day 180; 2,003 U/mL (GSD 6.7) at Day 270; and 8,403 U/mL (GSD 3.1) at Day 360. The increase was statistically significant from Day 21 to Day 90 (p<0.0001), Day 90 to Day 180 (p=0.0005), and Day 270 to Day 360 (p<0.0001). Participants with more severe initial infection demonstrated significantly higher antibody levels compared to those with milder infection at Day 21. Sixty-four patients had probable COVID-19 reinfection (incidence of 20.8%, 95% CI 16.4, 25.8%). The GMT of these 64 patients was 411.8 U/mL (GSD 6.9) prior to the occurrence of the probable reinfection. Majority (87.5%) were fully vaccinated. Antibody titers significantly affected the risk of developing reinfection, with adjusted hazard ratio of 0.994, 95% CI 0.992-0.996, p<0.001. Conclusion: Antibody levels against SARS-CoV-2 increased over a one-year follow-up. Higher antibody levels were observed among those with more severe initial infection and those vaccinated. Higher antibody levels are associated with a lower risk of probable reinfection.

Efficacy of lymphocyte immunotherapy in the treatment of recurrent pregnancy loss from alloimmunity: A systematic review and meta-analysis.

PROBLEM: The efficacy of lymphocyte immunotherapy (LIT) in the treatment of recurrent pregnancy loss (RPL) from alloimmunity has been debated for years. There is conflicting evidence on the therapeutic role of LIT, since the etiology of most cases of RPL is previously classified as idiopathic. METHOD OF STUDY: A systematic search of PubMed and Cochrane databases was done for randomized controlled trials that assessed the efficacy of paternal lymphocyte or third donor LIT among patients with primary or secondary RPL. The primary outcome was live birth rate after LIT. Random-effect meta-analysis was conducted using the software RevMan 5.4. Pre-planned subgroup analyses of source of lymphocytes, timing and frequency of administration, and concentration per immunization dose were conducted. RESULTS: Data from eight trials showed a statistically significant benefit of LIT (RR = 1.45, 95% CI 1.05-2.01). The overall live birth rate is higher in the treatment group (65.6%) compared to placebo or no treatment (45.2%). Subgroup analysis based on source of lymphocytes revealed a trend towards benefit with paternal LIT but with wide confidence interval (RR = 1.34, 95% CI = .84-2.14). Multiple doses of immunotherapy before pregnancy and low dose (5×106 cells) LIT showed significant benefit. Sensitivity analysis involving studies with a low risk of bias demonstrated significant benefit of increased live birth rate among patients treated with LIT compared to those who received placebo or no treatment (RR = 1.97, 95% CI = 1.53-2.53). CONCLUSION: LIT demonstrate benefit in improving pregnancy outcome of patients with RPL from alloimmunity.

Comparative effectiveness of probiotic strains on the prevention of pediatric atopic dermatitis: A systematic review and network meta-analysis.

BACKGROUND: Atopic dermatitis is the most common chronic skin disease affecting the pediatric population. Probiotics have been proposed to be effective in preventing the development of pediatric atopic dermatitis. Although studies show promise for the use of probiotics, the evidence is still inconclusive due to significant heterogeneity and imprecision. OBJECTIVE: To determine the comparative effectiveness of the different types of probiotic strains in preventing the development of atopic dermatitis among pediatric patients. METHODOLOGY: A systematic search of Cochrane Library, MEDLINE, TRIP Database, and Centre for Research and Dissemination was conducted. Manual search of the reference lists and search for unpublished articles were also done. All randomized controlled trials available from inception until April 12, 2020, on the use of probiotics in the prevention of atopic dermatitis among children were included. The comparator groups considered are other probiotic strains and placebo. The primary outcome of interest was the development of atopic dermatitis. Two authors independently searched for articles, screened the articles for inclusion, appraised the articles using the Cochrane risk of bias tool version 2, and extracted the data. In case of disagreement, the two authors discussed the source of disagreement until consensus was reached. If consensus was not reached, an independent third party reviewer was consulted. Frequentist network meta-analysis was conducted using STATA 14 software. The ranking probabilities and surface under the cumulative ranking curve (SUCRA) values were obtained to determine ranking of the different probiotic strains based on efficacy and safety data. RESULTS: We included 21 original studies represented by 35 records and a total of 5406 children with atopic dermatitis as diagnosed by clinicians or fulfillment of validated diagnostic criteria. All studies were randomized placebo-controlled trials. The top 3 probiotic preparations in terms of efficacy in reducing the risk of atopic dermatitis are Mix8 (Lactobacillus paracasei ST11, Bifidobacterium longum BL999), LP (Lactobacillus paracasei ssp paracasei F19) and Mix3 (Lactobacillus rhamnosus GG, Bifidobacterium animalis ssp lactis Bb-12). Mix8 compared with placebo probably reduces the risk of atopic dermatitis based on low-quality evidence (RR = 0.46, 95% CI 0.25-0.85). Mix3 compared with placebo also probably reduces the risk of atopic dermatitis based on low-quality evidence (RR = 0.50, 95% CI 0.27-0.94). It is uncertain whether LP compared with placebo reduces the risk of atopic dermatitis due to very-low-quality certainty of evidence (RR = 0.49, 95% CI 0.20-1.19). In terms of adverse events, LGG may slightly lead to less adverse events compared with placebo based on low-quality evidence (RR = 0.70, 95% CI 0.32-1.52). Mix4 may slightly lead to more adverse events compared with placebo based on low-quality evidence (RR = 1.06, 95% CI 0.02-51.88). Based on subgroup analysis of studies involving infants, Mix3 compared with placebo probably reduces the risk of atopic dermatitis based on low-quality evidence (RR = 0.46, 95% CI 0.22-0.97). In the subgroup analysis of studies where probiotics were administered to pregnant women and to infants, LRH compared with placebo probably reduces the risk of atopic dermatitis based on moderate-quality evidence (RR = 0.54, 95% CI 0.26-1.11). CONCLUSION: Certain probiotic preparations demonstrate efficacy in reducing the risk of developing atopic dermatitis when administered to pregnant women, infants, or both.

Primary immunodeficiency from B-cell defect: a case series of 6 patients seen in a national tertiary hospital in the Philippines.

Primary immunodeficiency disorders, although rare, pose a significant burden in the quality of life of afflicted patients and their families. The most common of these disorders are caused by B-cell defects. A total of 6 patients were seen and diagnosed in a national tertiary hospital in the Philippines from 1996 to 2018. These patients were admitted due to various infections, and were subsequently diagnosed to have B-cell defects. Four out of the 6 patients have genetic studies confirming the diagnosis of X-linked agammaglobulinemia. One patient succumbed to sepsis at 10 years of age, while the rest are on follow-up at the Philippine General Hospital for intravenous immunoglobulin infusion.

Predictors of serious outcomes among patients with anaphylaxis seen in the Philippine national tertiary hospital.

BACKGROUND: Anaphylaxis is a severe and life-threatening systemic hypersensitivity reaction. The incidence of anaphylaxis has increased significantly in recent years. OBJECTIVE: To identify predictors of serious outcomes among patients with anaphylaxis seen in the national tertiary hospital of the Philippines from 2015 to 2019. METHODS: Data was collected retrospectively through search of the medical records section and census reports on all patients diagnosed with anaphylaxis seen at the national tertiary hospital from 2015 to 2019. The patients' clinical profile, management, and outcome were extracted. Multiple logistic regression analysis was used to determine the association of clinical characteristics and physicians' management with the development of serious outcomes. Variable selection procedure through backward elimination method was used to determine significant predictors of serious outcomes of anaphylaxis. Data analysis was done using Stata 14 software. RESULTS: There were 300 patients with anaphylaxis seen at the Philippine national tertiary hospital from 2015 to 2019. Of the 300 patients, 179 were female (57.9%). The median age of the patients was 26 years old, with an interquartile range of 33 years. Only 75 patients (25%) had a past history of allergic disease. Majority of the patients (70%) had comorbidities. Drugs were the most common trigger of anaphylaxis (81.3%). Antibiotics were the most common type of drugs implicated (27%). Serious outcomes were noted in a total of 31 patients (10.3%). The significant predictors of serious outcomes in anaphylaxis are age (p = 0.034) and cofactors including use of beta-blockers and presence of acute infection (p < 0.001). CONCLUSION: In the Philippine national tertiary hospital, the incidence of anaphylaxis increased by 240% in the past decade. Predictors of serious outcome in anaphylaxis include increased age and presence of cofactors such as beta-blocker use and presence of acute infection.

Eosinophilic gastroenteritis in an adolescent male with history of chronic bullous disease.

Eosinophilic gastroenteritis is a rare inflammatory disorder of the gastrointestinal tract. Although commonly associated with allergic diseases, it is also rarely associated with autoimmune disorders. This case report describes a 17-year-old Filipino male with eosinophilic gastroenteritis, manifesting as abdominal pain, vomiting and diarrhoea. He had no allergic diseases, but he was previously diagnosed with chronic bullous disease. His symptoms improved with the initiation of corticosteroids. To date, this is the first case report of a patient with eosinophilic gastroenteritis and chronic bullous disease.

Comparative effectiveness of probiotic strains for the treatment of pediatric atopic dermatitis: A systematic review and network meta-analysis.

BACKGROUND: The current evidence on the use of probiotics in treating atopic dermatitis is inconclusive. This study determined the comparative effectiveness of the different types of probiotic strains in treating pediatric atopic dermatitis. METHODOLOGY: Systematic and manual search for all randomized controlled trials available from inception until January 31, 2020, was done. Two independent authors conducted the search, screening, appraisal, and data abstraction. Network meta-analysis was conducted using STATA 14 software. RESULTS: Twenty-two studies involving 28 different probiotic strains were included. The top three ranked probiotic strains in terms of efficacy are Mix1 (Bifidobacterium animalis subsp lactis CECT 8145, Bifidobacterium longum CECT 7347, and Lactobacillus casei CECT 9104); Lactobacillus casei DN-114001; and Mix6 (Bifidobacterium bifidum, Lactobacillus acidophilus, Lactobacillus casei, and Lactobacillus salivarius). Compared with placebo, Mix1 reduces atopic dermatitis symptoms with high certainty evidence (SMD -1.94, 95% CI -2.65 to -1.24; 47 participants). Mix6 compared with placebo probably reduces atopic dermatitis symptoms based on moderate certainty evidence (SMD -0.85, 95% CI -1.50 to -0.20; 40 participants). Lactobacillus casei DN-114001 compared with placebo may reduce atopic dermatitis symptoms based on low certainty evidence (SMD -1.35, 95% CI -2.04 to -0.65). In terms of safety, the highest ranked strain is Lactobacillus fermentum VRI-003, while the lowest ranked strain is Lactobacillus rhamnosus GG. CONCLUSION: Certain probiotic preparations show benefit in reducing allergic symptoms in pediatric atopic dermatitis.

Guidelines in Low and Middle Income Countries Paper 3: Appraisal of Philippine Clinical Practice Guidelines using Appraisal of Guidelines for Research and Evaluation II: improvement needed for rigor, applicability, and editorial independence.

BACKGROUND AND OBJECTIVE: High-quality clinical practice guidelines (CPGs) are needed to guide practitioners, policy makers, and other stakeholders to provide optimal health care. This study aims to appraise the CPGs developed in the Philippines using the AGREE II instrument. METHODS: Ninety-one CPGs were appraised independently by two health-care professionals. CPGs were considered acceptable if they garnered an overall mean score of at least 75.0% for all 6 domains and a domain score of at least 75.0% for rigor of development. A mean score of <75.0% on either of the criteria implied that the CPG needed revision. RESULTS: Overall mean scores of the CPGs ranged from 8.4% to 79.2%, with a mean of 43.9% (standard deviation = 13.4%). In general, CPGs scored better for the domains of clarity of presentation, scope and purpose, and stakeholder involvement. Lowest scores were obtained for the domains of rigor of development, applicability, and editorial independence. Only 1 (1.1%) CPG qualified as acceptable. CONCLUSION: AGREE II is a practical and useful guide in appraising the quality of CPGs. Strengthening technical capacity in various medical fields is essential to improve the quality of CPGs. Rigor of development, applicability issues, and editorial independence should be emphasized in CPG capacity-building activities.

Probiotics as treatment for food allergies among pediatric patients: a meta-analysis.

BACKGROUND: The burden of disease of food allergy is increasing worldwide. The standard of management is allergen avoidance and symptomatic treatment. Probiotics have been proposed to be beneficial for treatment and prevention of food allergy. OBJECTIVE: To determine the effectiveness of probiotic administration in treating food allergies among pediatric patients. METHODS: A systematic search of electronic medical literature databases was conducted. Manual search of the reference lists and search for unpublished articles were also done. All randomized controlled trials available from inception until February 19, 2018 were retrieved. The primary outcome of interest was relief of allergic symptoms, while the secondary outcome of interest was inducement of tolerance. Two independent authors did the search, screening, appraisal, and data abstraction. Data analysis and synthesis were done using RevMan 5.3 software. Subgroup analysis was done based on the probiotic strains and time periods in measuring the outcome. Exclusion sensitivity analysis was also done. RESULTS: Nine trials involving 895 pediatric patients with cow's milk allergy (CMA) were included in the review. The primary outcome of interest, relief of symptoms, was measured using the scoring index for eczema. Pooled results from two studies showed larger reduction in the scoring index among patients given probiotics, but this effect was imprecise (MD -1.30, 95% CI -3.88, 1.28). For the secondary outcome of interest, pooled results from four studies showed benefit of probiotics in inducing tolerance, but again this result is imprecise with significant heterogeneity (RR 0.58, 95% CI 0.34, 1.00). Subgroup analysis per probiotic strain showed benefit of Lactobacillus rhamnosus GG in inducing tolerance based on two studies involving infants with suspected cow's milk allergy (RR = 0.41, 95% CI 0.28 to 0.62). Another subgroup analysis showed a duration-dependent effect associated with probiotic usage, with inducement of tolerance noted after at least 2 years (RR = 0.44, 95% CI 0.29 to 0.67). CONCLUSION: Analysis of available evidence shows moderate certainty that the use of probiotics can relieve symptoms of children with cow's milk allergy. The reduction in certainty is due to imprecise results. Moreover, there is low certainty that probiotics can induce tolerance among children with cow's milk allergy, due to problems of imprecision and attrition bias. In the subgroup analysis, Lactobacillus rhamnosus GG administration likely results in inducing tolerance among infants with suspected cow's milk allergy. Only studies on CMA were analyzed since no studies were found on probiotics as treatment for other types of food allergy among children.
