Objectives: To estimate the proportion of TB patients who have access to mobile phones and to describe mobile phone utilization practices of TB patients.Methods: Six public and six private TB clinics representing the four districts of Metro Manila and one institution in Cavite were purposively selected for this cross-sectional survey conducted in 2006. Using an interviewer-administered questionnaire, patients suspected to have TB, those newly diagnosed and those currently on treatment under either DOTS or non-DOTS were interviewed.Results: Of the 337 patients interviewed, 65% (95% CI 60.2 to 70.6) have access to mobile phones (45% currently own a mobile phone and 20% share a mobile phone with a household member). The mean duration of ownership was 1.8 years (SD1.7). Almost all had prepaid subscriptions (99%) and 72% had some credit/load in their mobile phones at the time of interview. Of the three existing networks, subscription to SMART was highest, followed by the Globe network. Most of them use their phones for social purposes and emergency-related communications.Most of the respondents were male (60%) in the age group of 20-39 (54%) and 40-59 years old (33%). Half of the respondents were from public TB clinics (52%). On multivariable analysis, patients consulting in private clinics [OR 2.25, 95% CI 1.36 to 3.74], belonging to the younger age of

Objective. This study aimed to assess compliance with current best practice guidelines on the use of antibiotics in the Department of Surgery in the Philippine General Hospital and to determine the impact of the dissemination of an institution-based guideline on compliance and on patient outcomes. Methods. Two antibiotic use surveys were performed 4 weeks before and 4 weeks after the implementation and dissemination of the PGH Surgical Antibiotic Use Guidelines in the Department of Surgery. The medical records of eligible patients were reviewed regarding patient and case characteristics, details on the administration of antibiotics and the collection of specimen for culture studies. Data relating to the occurrence of surgical site infection within 30 days of the operation was extracted. Compliance with antibiotic use guidelines was assessed for each case. The compliance rates in the pre- and post-intervention periods were compared. Results. The study included a total of 477 patients, 213 in the pre-implementation and 264 in the post implementation period. Compared with the pre-intervention period, rates of compliance with guidelines improved for all parameters in the post-implementation period except for correct dosing. The greatest improvement was seen in the selection of the recommended drug, and proper duration. There was modest improvement in the timing of the preoperative drug administration. There was poor compliance with recommendations for appropriate specimen collection for culture studies, with marked improvement in collection in the pediatric group post intervention. Overall, the in-hospital SSI rate was reduced from 6.8% to 1.1%, while there was little change in the 30-day SSI rate, post-intervention. Conclusion. A simple intervention to raise awareness of institutional guidelines on antibiotic use in the surgical setting lead to a modest improvement on overall compliance, although rates of total compliance with all relevant guidance on antibiotic use, choice, dose, timing and duration remained low. The impact on surgical site infection rates based on such compliance was modest.

Introduction. In the attempt to control the spread of the disease and the pandemic, numerous COVID-19 vaccines are in development. A review of the evidence on their efficacy and safety are critical. Methods. A search for trials was done using the COVID-19 Living OVerview of Evidence (L·OVE) platform. We also searched for relevant authorization documents and trial reports for COVID-19 vaccines of the US-Food and Drug Authority (US-FDA), the European Medicines Agency (EMA), the United Kingdom Medicines and Health Products Regulatory Agency (MHRA), and the WHO website. We included studies that fulfilled the following inclusion criteria: population – humans; intervention – COVID-19 vaccines; comparison – control or placebo; outcomes – efficacy and adverse events; methods – phase 3 randomized trials. Two reviewers independently screened the reports, assessed the methodological quality, and extracted the data on the trial characteristics and results on vaccine efficacy and safety. The date of last search was March 11, 2021. Results. Interim results of trials investigating five vaccines were identified and included in the review. All five vaccines demonstrated satisfactory vaccine efficacy (VE) against symptomatic COVID-19 infection among adults in the short term with moderate certainty of evidence: BNT162b2, VE 95% (95% CI 90.3, 97.6); mRNA-1273, VE 93.6% (95% CI 88.6, 96.5); ChAdOx1, VE 66.7% (95% CI 57.4, 74.0), Gam-COVID-Vac, VE 91.1% (95% CI 83.6, 95.1); and Ad26.CoV2.S, VE 67.2% (95% CI 59.3, 73.7). Data on the efficacy against severe COVID-19 infection and asymptomatic COVID-19 infection are still inconclusive, except for Ad26.CoV2.S, which demonstrated good efficacy in preventing moderate and/or severe COVID-19 infection and acceptable protection against asymptomatic COVID-19 infection 28 days after vaccination (moderate certainty of evidence). Efficacy data on preventing death from COVID-19 infection are still inconclusive. Very limited phase 3 trial data is available to inform vaccine efficacy against the different variants of SARS-CoV-2. Vaccination with these five vaccines was associated with higher adverse reactions compared to control. These adverse events, due to reactions to the vaccines, were mild to moderate and of short duration. Available evidence on vaccine efficacy and safety is limited, mainly due to the short follow up and the small sample size of specific populations. Conclusion. BNT162b2, mRNA-1273, ChAdOx1, Gam-COVID-Vac and Ad26.CoV.S vaccines demonstrated satisfactory vaccine efficacy against symptomatic COVID-19 infection among adults in the short term with moderate certainty of evidence. Data on the efficacy against severe COVID-19 infection, asymptomatic COVID-19 infection, and death from COVID-19 infection are still inconclusive. Long-term efficacy and safety data, and data on the efficacy against variant strains of SARS-CoV-2 are still lacking.

Objectives: To describe the clinical profile and factors associated with mortality among the first 200 patients confirmed to have COVID-19 infection admitted in the University of the Philippines – Philippine General Hospital (UP-PGH) Methodology: We conducted a retrospective review of adult patients with confirmed COVID-19 infection admitted in PGH, a designated COVID-19 referral center. Demographic, clinical data, and clinical outcomes were extracted from medical records. Frequencies and distributions of various clinical characteristics were described, and factors associated with mortality were investigated. Results: Of the 200 patients in our cohort, majority were male (55.5%), and more than half (58%) were over 60 years old. Underlying co-morbid illnesses (67.5%) included hypertension (49.5%), diabetes mellitus (26.5%), and cardiovascular disease (20.5%). Most frequent presenting symptoms were cough (69.0%), fever (58.5%), or shortness of breath (53.0%). Most patients presented with mild (n=41, 20.5%) to moderate illness (n=99, 49.5%) and only 60 were considered severely (n=32, 16.0%) or critically ill (n=28, 14.0%). Many (61%) received empiric antibiotics, while 44.5% received either repurposed drugs or investigational therapies for COVID-19. Bacterial co-infection was documented in 11%, with Klebsiella pneumoniae commonly isolated. In-hospital mortality was 17.5%, which was highest for critical COVID-19 (71.4%). Mortality was observed to be higher among patients age 60 and above, those requiring oxygen, ventilatory support and ICU admission, and among those who developed acute kidney injury, acute stroke, sepsis, and nosocomial pneumonia. Conclusion: Our study confirms that COVID-19 affects males, older individuals and those with underlying co-morbid conditions. Empiric antimicrobial treatment was given for majority of patients, despite documentation of bacterial infection in only 11%. K. pneumoniae was commonly isolated, reflecting local epidemiology. Mortality rate during this early period of the pandemic was high and comparable to other institutions. Factors associated with mortality were related to critical COVID-19 and are similar to other studies.

Objectives. To determine the effect of prolonged cotrimoxazole prophylaxis (CP) in reducing hospitalization and opportunistic infection rates among people living with HIV (PLHIV) with CD4 count >200 cells/mm3. Methods. We retrospectively reviewed 349 medical charts of PLHIV with CD4 count (or T-cell count) of >200 cells/mm3 enrolled in an HIV treatment hub in Manila, Philippines, from January 2004 to July 2016. Demographic, clinical characteristics and outcomes were extracted. Descriptive statistics were generated. Chi-square test for two proportions was done to compare the difference in outcomes between the CP and non-CP groups. Results. Of the 349 patients, majority (96.6%) were male with a mean age of 28 years (SD 6.4) and mean CD4 count of 373 cells/mm3 (SD 148). CP was continued in 103 patients (29.5%) with mean duration of 1.7 (SD 1.9) years. The prolonged CP group had more events of adverse drug reactions (p200 cells/mm3. More adverse effects were also seen in the CP group.

Objective. This study aimed to describe dengue burden in the Philippines. Specifically, health and economic costs of the disease were estimated. Methods. A published serotype-specific and age-stratified dengue dynamic transmission model was populated with Philippine-specific dengue epidemiology and cost data. Data were gathered from literature and record reviews. Dengue experts were consulted to validate the model parameters. Sensitivity analyses were performed to test the uncertainty of input parameters on model outcomes. Results. By 2016 to 2020, it is estimated that annually, average hospitalized cases will amount to 401,191 and ambulatory cases will amount to 239,497; resulting to USD 139 million (PhP 5.9 billion) and USD 19 million (PhP 827 million) worth of aggregate costs shouldered by the public payer for hospitalized and ambulatory cases, respectively. Average annual productivity losses may amount to USD 19 million (PhP 821 million) and DALY lost is expected to be 50,622. Conclusion. The cost of dengue is high especially since the Philippines is an endemic country. Thus, there is a need to optimize government interventions such as vector control and vaccination that aim to prevent dengue infections.
