Early experience with COVID-19 patients in a private tertiary hospital in the Philippines: Implications on surge capacity, healthcare systems response, and clinical care.

BACKGROUND: Our healthcare institution was one of the first to see SARS CoV-2 cases in the country. We describe the early COVID-19 experience of a private hospital in the Philippines and discuss the healthcare system response in the setting of surge capacity. METHODS: We reviewed the medical records of adult COVID-19 hospitalized patients admitted in March 2020. We reported their demographic and clinical characteristics using descriptive statistics. RESULTS: Of 40 patients admitted, 23 (57.5%) were male and 19 (47.5%) were aged <60 years. Most (n = 27, 67.5%) had moderate-risk, 9 (22.5%) had high-risk, and 4 (10%) had low-risk COVID-19. SARS-CoV-2 testing took 5.5 (range 1-10) days. Overall mortality rate was 6/40 (15.0%). Clinical cure was documented in all low-risk patients, 25 (92.6%) moderate-risk patients, and only 1 (11.1%) high-risk patient. In response to the surge, the hospital rapidly introduced one-way traffic systems, dedicated screening, triage and Emergency Department areas for COVID-19, a clinical pathway, engineering controls, patient cohorting, and strict infection prevention and control measures. CONCLUSION: Majority of patients recovered from COVID-19. Older age and high-risk pneumonia were associated with poor outcomes. Adaptations to hospital structure and staff were quickly made in response to surge capacity, although our response was hampered by prolonged time to COVID-19 confirmation. Our study underscores the urgent need for rapid adaptive response by the healthcare system to address the surge of cases.

Behavioural change: a rare presentation of leptospirosis.

Neurological manifestations of leptospirosis without severe multiorgan involvement are a rare clinical entity. Despite the increasing prevalence of the disease in many tropical countries, its protean clinical presentations make its timely diagnosis challenging. We report the case of a 44-year-old Filipino man presenting with fever, myalgia, behavioural changes and altered sensorium. Neurological examination did not show any focal neurological deficits or clear signs of meningoencephalitis. Lumbar tap, cranial CT scan and cranial MRI were inconclusive. The diagnosis of leptospirosis with acute encephalitis relied heavily on the patient's clinical clues, appropriate exposure history and patterns in ancillary laboratory tests. Empiric antibiotic therapy with ceftriaxone was initiated. Seroconversion and fourfold increase in serological antibody titres by leptospirosis microagglutination test later confirmed the diagnosis. The patient was successfully treated, and all neurological complications were reversed.

Increased predominance of HIV-1 CRF01_AE and its recombinants in the Philippines.

The growth rate of new HIV infections in the Philippines was the fastest of any countries in the Asia-Pacific region between 2010 and 2016. To date, HIV-1 subtyping results in the Philippines have been determined by characterizing only partial viral genome sequences. It is not known whether recombination occurs in the majority of unsequenced genome regions. Near-full-length genome (NFLG) sequences were obtained by amplifying two overlapping half genomes from plasma samples collected between 2015 and 2017 from 23 newly diagnosed infected individuals in the Philippines. Phylogenetic analysis showed that the newly characterized sequences were CRF01_AE (14), subtype B (3), CRF01/B recombinants (5) and a CRF01/CRF07/B recombinant (1). All 14 CRF01_AE formed a tight cluster, suggesting that they were derived from a single introduction. The time to the most recent common ancestor (tMRCA) for CRF01_AE in the Philippines was 1995 (1992-1998), about 10-15 years later than that of CRF01_AE in China and Thailand. All five CRF01/B recombinants showed distinct recombination patterns, suggesting ongoing recombination between the two predominant circulating viruses. The identification of partial CRF07_BC sequences in one CRF01/CRF07/B recombinant, not reported previously in the Philippines, indicated that CRF07_BC may have been recently introduced into that country from China, where CRF07_BC is prevalent. Our results show that the major epidemic strains may have shifted to an increased predominance of CRF01_AE and its recombinants, and that other genotypes such as CRF07_BC may have been introduced into the Philippines.

Predictors of Outcome and Severity in Adult Filipino Patients with Febrile Neutropenia.

Aim. The study aimed to describe the profile of Filipino febrile neutropenia patients and to determine parameters associated with severe outcomes. Methods. This is a retrospective study of Filipino febrile neutropenia patients admitted to the Philippine General Hospital. Patients were described in terms of clinical presentation and stratified according to the presence or absence of severe outcomes. Prognostic factors were then identified using regression analysis. Results. 115 febrile episodes in 102 patients were identified. Regression analysis yielded prolonged fever >7 days prior to admission (OR 2.43; 95% CI, 0.77-7.74), isolation of a pathogen on cultures (OR 2.69; 95% CI, 1.04-6.98), and nadir absolute neutrophil count (ANC) < 100 during admission (OR 1.96; 95% CI, 0.75-5.12) as significant predictors of poor outcome. Factors that significantly correlated with better outcome were granulocyte colony-stimulating factor (G-CSF) use (OR 0.31; 95% CI, 0.11-0.85) and completeness of antibiotic therapy (OR 0.26; 95% CI, 0.10-0.67). Conclusion. Prolonged fever >7 days prior to admission, positive pathogen on cultures, and nadir ANC < 100 during admission predicted severe outcomes, whereas G-CSF use and complete antibiotic therapy were associated with better outcomes. These prognostic variables might be useful in identifying patients that need more intensive treatment and monitoring.

Impact of an International Nosocomial Infection Control Consortium multidimensional approach on catheter-associated urinary tract infections in adult intensive care units in the Philippines: International Nosocomial Infection Control Consortium (INICC) findings.

OBJECTIVES: To assess the impact of a multidimensional infection control approach on the reduction of catheter-associated urinary tract infection (CAUTI) rates in adult intensive care units (AICUs) in two hospitals in the Philippines that are members of the International Nosocomial Infection Control Consortium. MATERIALS AND METHODS: This was a before-after prospective active surveillance study to determine the rates of CAUTI in 3183 patients hospitalized in 4 ICUS over 14,426 bed-days. The study was divided into baseline and intervention periods. During baseline, surveillance was performed using the definitions of the US Centers for Disease Control and Prevention and the National Healthcare Safety Network (CDC/NHSN). During intervention, we implemented a multidimensional approach that included: (1) a bundle of infection control interventions, (2) education, (3) surveillance of CAUTI rates, (4) feedback on CAUTI rates, (5) process surveillance and (6) performance feedback. We used random effects Poisson regression to account for the clustering of CAUTI rates across time. RESULTS: We recorded 8720 urinary catheter (UC)-days: 819 at baseline and 7901 during intervention. The rate of CAUTI was 11.0 per 1000 UC-days at baseline and was decreased by 76% to 2.66 per 1000 UC-days during intervention [rate ratio [RR], 0.24; 95% confidence interval [CI], 0.11-0.53; P-value, 0.0001]. CONCLUSIONS: Our multidimensional approach was associated with a significant reduction in the CAUTI rates in the ICU setting of a limited-resource country.

Prevalence and risk factors for HIV infection among men having sex with men in Metro Manila, Philippines.

HIV incidence in the Philippines is increasing at an alarming rate. We conducted this study to understand the factors catalyzing the HIV epidemic among men having sex with men (MSM) in Metro Manila. From November 2009 to January 2010, an HIV testing booth was set up adjacent to bars and restaurants in Metro Manila frequented by MSM at night. Participants aged > or =18 years were interviewed using a structured questionnaire. Rapid HIV antibody screening was performed using SD Bioline HIV 1/2 3.0 (Standard Diagnostics). Of 406 MSM included in the study, the mean age was 26.2 years [standard deviation (SD) 5.4]; 96% believed condoms reduced HIV risk but only 3% reported consistent use. The leading reasons for not using condoms were belief that the partner was HIV negative (34.4%), diminished pleasure (32%), and unavailability (23.4%). The HIV prevalence using the rapid test was 11.8% [95% confidence interval (CI): 8.7- 15.0]. All 40 cases who had a confirmatory Western blot test were positive, of whom 24 were business process outsourcing employees (BPOEs). On multivariate analysis, work as a BPOE [adjusted OR (aOR): 3.37; p=0.001], preference for receptive anal sex (aOR: 5.26; p=0.04), and sex while under the influence of excessive alcohol (aOR: 2.71; p=0.04) were independently associated with HIV. The proportion of BPOEs who consistently use condoms when having insertive anal sex with a stranger was significantly lower compared to non-BPOEs (24.5% versus 38.2%; p=0.02). Urgent interventions are needed to address the HIV epidemic in the Philippines.

Findings of the International Nosocomial Infection Control Consortium (INICC), Part II: Impact of a multidimensional strategy to reduce ventilator-associated pneumonia in neonatal intensive care units in 10 developing countries.

Design. Before-after prospective surveillance study to assess the efficacy of the International Nosocomial Infection Control Consortium (INICC) multidimensional infection control program to reduce the rate of occurrence of ventilator-associated pneumonia (VAP). Setting. Neonatal intensive care units (NICUs) of INICC member hospitals from 15 cities in the following 10 developing countries: Argentina, Colombia, El Salvador, India, Mexico, Morocco, Peru, Philippines, Tunisia, and Turkey. Patients. NICU inpatients. Methods. VAP rates were determined during a first period of active surveillance without the implementation of the multidimensional approach (phase 1) to be then compared with VAP rates after implementation of the INICC multidimensional infection control program (phase 2), which included the following practices: a bundle of infection control interventions, education, outcome surveillance, process surveillance, feedback on VAP rates, and performance feedback on infection control practices. This study was conducted by infection control professionals who applied National Health Safety Network (NHSN) definitions for healthcare-associated infections and INICC surveillance methodology. Results. During phase 1, we recorded 3,153 mechanical ventilation (MV)-days, and during phase 2, after the implementation of the bundle of interventions, we recorded 15,981 MV-days. The VAP rate was 17.8 cases per 1,000 MV-days during phase 1 and 12.0 cases per 1,000 MV-days during phase 2 (relative risk, 0.67 [95% confidence interval, 0.50-0.91]; [Formula: see text]), indicating a 33% reduction in VAP rate. Conclusions. Our results demonstrate that an implementation of the INICC multidimensional infection control program was associated with a significant reduction in VAP rate in NICUs in developing countries.

Device-associated infections rates in adult, pediatric, and neonatal intensive care units of hospitals in the Philippines: International Nosocomial Infection Control Consortium (INICC) findings.

BACKGROUND: This study investigated the rate of device-associated health care-associated infection (DA-HAI), microbiological profiles, bacterial resistance, length of stay (LOS), and mortality rate in 9 intensive care units (ICUs) of 3 hospital members of the International Nosocomial Infection Control Consortium (INICC) in the Philippines. METHODS: This was an open-label, prospective cohort, active DA-HAI surveillance study of adult, pediatric, and newborn patients admitted to 9 tertiary care ICUs in the Philippines between January 2005 and December 2009, implementing methodology developed by the INICC. Data collection was performed in the participating ICUs, and data were uploaded and analyzed at the INICC headquarters using proprietary software. DA-HAI rates were registered based on definitions promulgated by the Centers for Disease Control and Prevention's National Healthcare Safety Network. RESULTS: Over a 5-year period, 4952 patients hospitalized in ICUs for a total of 40,733 days acquired 199 DA-HAIs, for an overall rate of 4.9 infections per 1,000 ICU-days. Ventilator-associated pneumonia posed the greatest risk (16.7 per 1,000 ventilator-days in the adult ICUs, 12.8 per 1,000 ventilator-days in the pediatric ICU, and 0.44 per 1,000 ventilator-days in the neonatal ICUs), followed by central line-associated bloodstream infections (4.6 per 1,000 catheter-days in the adult ICUs, 8.23 per 1,000 ventilator-days in the pediatric ICU, and 9.6 per 1,000 ventilator-days in the neonatal ICUs) and catheter-associated urinary tract infections (4.2 per 1,000 catheter-days in the adult ICUs and 0.0 in the pediatric ICU). CONCLUSION: DA-HAIs pose far greater threats to patient safety in Philippine ICUs than in US ICUs. The establishment of active infection control programs that involve infection surveillance and implement guidelines for prevention can improve patient safety and should become a priority.

Impact of International Nosocomial Infection Control Consortium (INICC) strategy on central line-associated bloodstream infection rates in the intensive care units of 15 developing countries.

BACKGROUND: The International Nosocomial Infection Control Consortium (INICC) was established in 15 developing countries to reduce infection rates in resource-limited hospitals by focusing on education and feedback of outcome surveillance (infection rates) and process surveillance (adherence to infection control measures). We report a time-sequence analysis of the effectiveness of this approach in reducing rates of central line-associated bloodstream infection (CLABSI) and associated deaths in 86 intensive care units with a minimum of 6-month INICC membership. METHODS: Pooled CLABSI rates during the first 3 months (baseline) were compared with rates at 6-month intervals during the first 24 months in 53,719 patients (190,905 central line-days). Process surveillance results at baseline were compared with intervention period data. RESULTS: During the first 6 months, CLABSI incidence decreased by 33% (from 14.5 to 9.7 CLABSIs per 1,000 central line-days). Over the first 24 months there was a cumulative reduction from baseline of 54% (from 16.0 to 7.4 CLABSIs per 1,000 central line-days; relative risk, 0.46 [95% confidence interval, 0.33-0.63]; P < .001). The number of deaths in patients with CLABSI decreased by 58%. During the intervention period, hand hygiene adherence improved from 50% to 60% (P < .001); the percentage of intensive care units that used maximal sterile barriers at insertion increased from 45% to 85% (P < .001), that adopted chlorhexidine for antisepsis increased from 7% to 27% (P < .001), and that sought to remove unneeded catheters increased from 37% to 83% (P < .001); and the duration of central line placement decreased from 4.1 to 3.5 days (P < .001). CONCLUSIONS: Education, performance feedback, and outcome and process surveillance of CLABSI rates significantly improved infection control adherence, reducing the CLABSI incidence by 54% and the number of CLABSI-associated deaths by 58% in INICC hospitals during the first 2 years.

International Nosocomial Infection Control Consortium (INICC) report, data summary for 2003-2008, issued June 2009.

We report the results of the International Infection Control Consortium (INICC) surveillance study from January 2003 through December 2008 in 173 intensive care units (ICUs) in Latin America, Asia, Africa, and Europe. During the 6-year study, using Centers for Disease Control and Prevention (CDC) US National Healthcare Safety Network (NHSN; formerly the National Nosocomial Infection Surveillance system [NNIS]) definitions for device-associated health care-associated infection, we collected prospective data from 155,358 patients hospitalized in the consortium's hospital ICUs for an aggregate of 923,624 days. Although device utilization in the developing countries' ICUs was remarkably similar to that reported from US ICUs in the CDC's NHSN, rates of device-associated nosocomial infection were markedly higher in the ICUs of the INICC hospitals: the pooled rate of central venous catheter (CVC)-associated bloodstream infections (BSI) in the INICC ICUs, 7.6 per 1000 CVC-days, is nearly 3-fold higher than the 2.0 per 1000 CVC-days reported from comparable US ICUs, and the overall rate of ventilator-associated pneumonia (VAP) was also far higher, 13.6 versus 3.3 per 1000 ventilator-days, respectively, as was the rate of catheter-associated urinary tract infection (CAUTI), 6.3 versus 3.3 per 1000 catheter-days, respectively. Most strikingly, the frequencies of resistance of Staphylococcus aureus isolates to methicillin (MRSA) (84.1% vs 56.8%, respectively), Klebsiella pneumoniae to ceftazidime or ceftriaxone (76.1% vs 27.1%, respectively), Acinetobacter baumannii to imipenem (46.3% vs 29.2%, respectively), and Pseudomonas aeruginosa to piperacillin (78.0% vs 20.2%, respectively) were also far higher in the consortium's ICUs, and the crude unadjusted excess mortalities of device-related infections ranged from 23.6% (CVC-associated bloodstream infections) to 29.3% (VAP).

Reminder systems and late patient tracers in the diagnosis and management of tuberculosis.

BACKGROUND: Reminder systems and late patient tracers as strategies to improve patients' adherence to tuberculosis screening, diagnosis, and treatment are used in some countries, but their effectiveness has not previously been systematically reviewed. OBJECTIVES: To assess the effects of reminder systems and late patient tracers on completion of diagnostics, commencement of treatment in people referred for curative or prophylactic treatment of tuberculosis, completion of treatment in people starting curative or prophylactic treatment for tuberculosis, and cure in people being treated for active tuberculosis. SEARCH STRATEGY: We searched the Cochrane Infectious Diseases Group Specialized Register (June 2008), Cochrane Effective Practice and Organization of Care Group Specialized Register (April 2007), CENTRAL (The Cochrane Library 2008, Issue 2), MEDLINE (1966 to June 2008), EMBASE (1974 to June 2008), LILACS (1982 to June 2008), CINAHL (1982 to June 2008), SCI-EXPANDED (1945 to June 2008), SSCI (1956 to June 2008), mRCT (June 2008), Indian Journal of Tuberculosis (1983 to June 2008), and reference lists. We also contacted researchers working in the field. SELECTION CRITERIA: Randomized controlled trials (RCTs), including cluster RCTs and quasi-RCTs, and controlled before-and-after studies comparing any reminders or late patient tracers with no or other kinds of reminders or late patient tracers. We included people in any setting who require treatment for tuberculosis or require prophylaxis against tuberculosis and are referred to tuberculosis diagnostic or screening services. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial risk of bias and extracted data. No meta-analysis could be undertaken due to the heterogeneity of interventions across trials. MAIN RESULTS: Nine trials involving 5257 participants met the inclusion criteria. Three assessed the use of late patient tracers, and six assessed reminder systems. Late patient tracers (home visit and letter) were shown to be beneficial in increasing adherence to tuberculosis treatment compared with no late patient tracer. The results from almost all the reminder trials, except one, show benefits of different types of reminders compared to no reminder on adherence to tuberculosis clinic appointments. AUTHORS' CONCLUSIONS: The included trials show significantly better outcomes among those tuberculosis patients for which late patient tracers and reminders are used. Studies of good quality (large and with rigorous study design) are needed to decide the most effective late patient tracer actions and reminders in different settings. Future studies of reminders in chemoprophylaxis and treatment settings would be useful.
