Triage practices for emergency care delivery: a qualitative study among febrile patients and healthcare workers in a tertiary care hospital in Nepal.

BACKGROUND: Improving screening and triage practices is essential for early severity assessments at the first point of contact and ensuring timely attention by healthcare workers (HCWs). The main objective of this study was to explore the triage process among febrile patients and HCWs in the emergency department (ED) of a tertiary care hospital in a resource-constrained setting. METHODS: This qualitative study was conducted from March to May 2023 at the ED of Tribhuvan University Teaching Hospital (TUTH), Nepal. The study included in-depth interviews with febrile patients (n = 15) and HCWs (n = 15). Additionally, direct observation notes (n = 20) were collected to document the triage process and patients' experiences in the ED. Data underwent thematic analysis using the Interpretative Phenomenological Analysis (IPA) approach. RESULTS: The ED of TUTH offered comprehensive triage services with clear delineation for the severity of febrile patients in line with the World Health Organization (WHO) guidelines. Nonetheless, challenges and constraints were identified. In the ED, evenings were generally the busiest period, and the triage process was not thorough during night shifts. Perception of triage was limited among patients and variable among HCWs. Digitalizing recordings of patient information including payment was deemed necessary for effective management of patients' waiting times at the triage station. High patient throughput added pressure on HCWs and had a potential influence on the delivery of services. Availability of medical equipment and space were also identified as challenges, with patients sometimes compelled to share beds. There were constraints related to waste disposal, hygiene, cleanliness, and the availability and maintenance of washrooms. Febrile patients experienced delays in receiving timely consultations and laboratory investigation reports, which affected their rapid diagnosis and discharge; nonetheless, patients were satisfied with the overall healthcare services received in the ED. CONCLUSIONS: Improving current triage management requires resource organization, including optimizing the waiting time of patients through a digitalized system. Urgent priorities involve upgrading visitor facilities, patient consultations, laboratory investigations, hygiene, and sanitation. HCWs' recommendations to resource the ED with more equipment, space, and beds and a dedicated triage officer to ensure 24-hour service, together with training and incentives, warrant further attention.

Prescribing Pattern of Antibiotics among Hospitalized Patients with Urinary Tract Infection.

BACKGROUND: Urinary tract infection is one of the most common bacterial infections worldwide. It has become one of the most common cause for the hospitalization and sepsis. It is generally treated with antimicrobial agents and fluids. This study was conducted to study the prescribing pattern of antibiotic among hospitalized patients with urinary tract infection. METHODS: A descriptive cross-sectional study was conducted in Nepal Medical College Teaching Hospital, Attarkhel, Kathmandu from January 2022 to April 2022. Patients aged 18 years or above of both sex, admitted to various departments with the provisional diagnosis of urinary tract infection prescribed with antibiotics were included in the study. RESULTS: Out of 146 patients admitted with a diagnosis of urinary tract infection, the most commonly prescribed antibiotics during hospital stay were cephalosporin in 102 (69.9%) patients followed by combination of penicillin and beta-lactamase inhibitors (31, 21.2%) and fluoroquinolones (15, 10.3%). Ceftriaxone (78, 53.4%) alone was the most commonly prescribed antibiotic as empirical therapy followed by combination of piperacillin and tazobactam (22, 15.1%). One hundred and forty four (78.6%) patients were prescribed antibiotics from the watch group followed by the access group (21, 11.5 %). E. coli was the most common organism isolated in 29 (76.3%) patients. CONCLUSIONS: Cephalosporin was the commonest antibiotic group prescribed in hospitalized patients among which ceftriaxone was commonly prescribed as an empirical therapy. Among AWaRe classification, antibiotics from the watch group were commonly prescribed.

Diagnostics for Typhoid Fever: Current Perspectives and Future Outlooks for Product Development and Access.

Typhoid is an enteric disease caused by Salmonella Typhi. Like many febrile illnesses, typhoid presents with nonspecific symptoms. In routine healthcare settings in low- and middle-income countries, typhoid fever is suspected and treated empirically. Though many diagnostic tests are available for typhoid diagnosis, there are currently no diagnostic tests that meet ideal requirements for sensitivity, specificity, speed, and cost-effectiveness. With introduction of typhoid conjugate vaccine, it is essential to explore the current and future typhoid approach in the context of use case and access to ensure their utilization for disease control.

Comparative Analysis of Commercially Available Typhoid Point-of-Care Tests: Results of a Prospective and Hybrid Retrospective Multicenter Diagnostic Accuracy Study in Kenya and Pakistan.

Blood and bone marrow cultures are considered the gold standard for the diagnosis of typhoid, but these methods require infrastructure and skilled staff that are not always available in low- and middle-income countries where typhoid is endemic. The objective of the study is to evaluate the sensitivity and specificity of nine commercially available Salmonella Typhi rapid diagnostic tests (RDTs) using blood culture as a reference standard in a multicenter study. This was a prospective and retrospective multicenter diagnostic accuracy study conducted in two geographically distant areas where typhoid is endemic (Pakistan and Kenya; NCT04801602). Nine RDTs were evaluated, including the Widal test. Point estimates for sensitivity and specificity were calculated using the Wilson method. Latent class analyses were performed using R to address the imperfect gold standard. A total of 531 serum samples were evaluated (264 blood culture positive; 267 blood culture negative). The sensitivity of RDTs varied widely (range, 0 to 78.8%), with the best overall performance shown by Enterocheck WB (72.7% sensitivity, 86.5% specificity). In latent class modeling, CTK IgG was found to have the highest sensitivity (79.1%), while the highest overall accuracy was observed with Enterocheck (73.8% sensitivity, 94.5% specificity). All commercially available Salmonella Typhi RDTs evaluated in the study had sensitivity and specificity values that fell below the required levels to be recommended for an accurate diagnosis. There were minimal differences in RDT performances between regions of endemicity. These findings highlight the clear need for new and more-accurate Salmonella Typhi tests.

Introduction: Ampicillinase C beta-lactamase-producing organisms are often resistant to multiple antimicrobial agents, and therapeutic options against these pathogens are limited. Limited information is available regarding Ampicillinase C beta-lactamase producers. The aim of this study was to find out the prevalence of Ampicillinase C beta-lactamase producers among isolates of Enterobacteriaceae in a tertiary care centre. Methods: A descriptive cross-sectional study was carried out in the Clinical Microbiology Laboratory of a tertiary care centre from May 2021 to October 2021. Ethical approval was received from the Institutional Review Committee (Reference number: 044-077/078). Isolates of Enterobacteriaceae from various clinical samples were collected by convenience sampling. Ampicillinase C screening for beta-lactamase producers among the Enterobacteriaceae isolates was done using cefoxitin (30 µg) disc. Detection of Ampicillinase C beta-lactamase producers among the screen-positive isolates was done by cefoxitin-cloxacillin double-disc synergy test. An increase in the zone size of ≥4 mm was considered as Ampicillinase C beta-lactamase producers. Point estimate and 95% Confidence Interval were calculated. Results: Among the total 481 isolates of Enterobacteriaceae, 49 (10.19%) (7.50-12.90, 95 % Confidence Interval) were detected as Ampicillinase C beta-lactamase producers among isolates of Enterobacteriaceae. Conclusions: The prevalence of Ampicillinase C beta-lactamase producers was lower than in other studies done in similar settings. Meropenem could be a drug of choice for the treatment of infections due to Ampicillinase C beta-lactamase-producing gram-negative bacteria. Keywords: antibiotic; beta-lactamase; Enterobacteriaceae; gram-negative bacteria.

Onychomycosis among Clinically Suspected Cases Attending the Dermatology Out-patient Department of a Tertiary Care Centre: A Descriptive Cross-sectional Study.

INTRODUCTION: Onychomycosis is a fungal disease of the nail apparatus caused by dermatophytes, non-dermatophytes and yeasts. Although onychomycosis is rarely life threatening, its high incidence and the associated morbidity makes it an important public health problem. This study was aimed to find the prevalence of onychomycosis among clinically suspected patients attending the outpatient department of Dermatology and Venereology. METHODS: A descriptive cross-sectional study was done in a total of 200 clinically suspected cases of onychomycosis attending the Dermatology outpatient department of a tertiary care hospital within the period of one year from 1st September 2019 to 31st August 2020. Ethical approval (Reference: 150320196) was taken and convenience sampling was done. Data were analyzed using Statistical Package for Social Sciences version 19. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS: Out of 200 clinically suspected cases prevalence of onychomycosis was found to be 40 (20%) (Confidence Interval = 19.94-20.06) by both direct microscopy and culture. Onychomycosis was commonest among age group of 21-40 years and more predominant among male patients 60 (65.21%). The fingernails were frequently involved i.e., 58 (63%) cases followed by toenails 34 (21%). Dermatophytes were the most common type of fungal infection accounting for 25 (62.5%). CONCLUSIONS: The study highlighted dermatophytes as the most common clinical pattern of onychomycosis and Trichophyton rubrum as the most common aetiological agent causing onychomycosis.

Antibiotics Self-Medication Practice Among Medical Students.

BACKGROUND: Self-medication of antibiotics is common among healthcare students due to their knowledge of pharmacology of antibiotics, which produces a false sense of confidence in self-diagnosis of disease conditions. Hence, this study was conducted to assess the practice of self-medication with antibiotics among medical students. METHODS: This questionnaire based descriptive, cross-sectional study was conducted in Nepal Medical College Teaching Hospital, Attarkhel, Kathmandu from September 2019 to February 2020 on the Bachelor of Medicine and Bachelor of Surgery students. RESULTS: Out of 405 students, 214 (52.8%) students had practiced antibiotics self-medication. The most commonly self-medicated antibiotics were azithromycin 126(58.9%), amoxicillin 67(31.3%), metronidazole 35(16.4%) and ciprofloxacin 14(6.5%) that were most commonly used for sore throat 93(43.5%), fever 82(38.3%), common cold 59(27.6%) and cough 43(20.1%).The common sources for self-medication were previous prescription 66 (30.8%), followed by own pharmacological knowledge 58 (27.1%). The most common reasons for practicing antibiotics self-medication were stated as previous experience of same illness 165 (77.1%), doctor's advice not deemed necessary 21 (9.8%) and save time 14 (6.6%). Large number of students agreed that antibiotics self-medication was not an acceptable practice 308(76.1%) and can lead to antimicrobial resistance 363(89.6%). CONCLUSIONS: More than half of the respondent medical students had practiced antibiotics self-medication. Sore throat was the commonest cause for it while the most commonly self-medicated antibiotic was azithromycin. Self-medication with antibiotics in medical students is concerning because they are future prescribers of antibiotics; who are supposed to promote rational use of antibiotics.

Prevalence of Intestinal Parasitic Infestation among Public School Children of a Community.

INTRODUCTION: Intestinal parasitic infestation is one of the major health problems in developing countries like Nepal. This study was done to determine the prevalence rate of intestinal parasitic infestation among school children in Duwakot VDC, Bhaktapur, Nepal. METHODS: A descriptive cross-sectional study was done in 194 public school children of Duwakot village development committee from August to October, 2019. Ethical clearance was obtained from the Institutional Review Committee (reference no. 1207201915). Simple random sampling was done. One hundred and ninety-four public school children individuals of 6 to 14 years of age were enrolled. Collected stools were examined for the presence of parasites macroscopically and microscopically. Microscopic examination was carried out by direct wet mount using normal saline (0.9%) and Lugol's iodine (0.5%) mount. The data obtained were computed and analyzed using Statistical Package for the Social Sciences version 16.0. RESULTS: A total of 194 stool samples were collected from school children and examined. The prevalence of intestinal parasitosis was 26 (13.40%). The commonest organism was Giardia lamblia in 22 (11.34%) cases. Among helminthic infection, 2 (1.03%) cases each were infected by Hymenolepis nana and Hookworm respectively. CONCLUSIONS: The prevalence rate of intestinal parasite infestation in Nepal shows considerable decline in recent years. However, more effort is required by public health resources to minimize the problem further.

Dermatophytes in Skin, Nail and Hair among the Patients Attending Out Patient Department.

BACKGROUND: Dermatophytosis are the most common types of cutaneous fungal infection seen in human and animals affecting skin, hair and nails caused by dermatophytes. The diagnosis of dermatophytes is based on the clinical observation and laboratory diagnosis by direct microscopic examination and fungal cultures. The present study is undertaken to isolate different type of dermatophytes causing fungal infection. METHODS: A prospective cross-sectional study design was used in a total of 90 clinically suspected cases of dermatophytic infection attending the out patient department of Kathmandu Medical College and Teaching hospital (KMCTH). Skin scraping, hair and nail samples were collected from the patients and were processed by direct microscopy and culture using standard protocol. Dermatophytes were identified based on the microscopic arrangement of microconidia and macroconidia. RESULTS: Dermatophytosis was more common in the age group of 21-40 years and was more predominant among male with male to female ratio of 1.7: 1. Among the total clinically suspected cases of dermatophytosis, 53 were positive in direct microscopy and only a total of 20 were positive by culture. Most common clinical type observed in our study was Tinea corporis(25%) followed by Tinea cruris. Trichophyton rubrum(50%) was the commonest aetiological agent in majority of clinical types followed by Trychophyton mentagrophytes(35%). CONCLUSIONS: The study highlighted T. corporis followed by T. cruris and T. unguim as the most common clinical pattern of dermatophytosis with a male predominance and 21-40 years being the most affected age group. T. rubram was the most common aetiological agent causing dermatophytosis.

Antibiotic sensitivity test of misolated pathogens was done using Muller Hinton Agar by Kirby-Bauer method. Statistical analysis was done by Excel 2018, point estimate at 95% confidence interval was calculated along with frequency and proportion for binary data. RESULTS: Out of the 666 bacteria isolated from clinical specimens, 133 (19.96%) were Staphylococcus aureus at 95% confidence interval (12.91-13.60%). Seventy nine (78.95%) of which is isolated from pus and wound infections. Out of 133 Staphylococcus aureus, 94 (70.64%) were Methicillin-Resistant Staphylococcus aureus. CONCLUSIONS: This study provides valuable information regarding the high prevalence of Staphylococcus aureus from pus and wound infections. The alarming number of Methicillin-Resistant Staphylococcus aureus is worrisome finding. Antibiotics like Vancomycin and Linezolid which has not developed resistance should be cautiously used only in Methicillin-Resistant Staphylococcus aureus cases.

Biofilm Formation and Extended-Spectrum Beta-Lactamase Producer among Acinetobacter Species Isolated in a Tertiary Care Hospital: A Descriptive Cross-sectional Study.

INTRODUCTION: Acinetobacter species are short, stout, gram-negative coccobacilli, generally considered to be a relatively low-grade pathogen. However, its resistance towards multiple classes of antibiotics through an array of resistance mechanisms including its ability to form biofilm has led to its emergence as an important pathogen in hospital settings. This study was done to determine the prevalence of biofilm former and Extended-spectrum Beta-Lactamase producer among Acinetobacter species. METHODS: A descriptive cross-sectional study was done in the clinical microbiology laboratory, Kathmandu Medical College from January to June 2019. Convenient sampling method was used. Ethical approval was taken from the Institutional Review Committee, Ref no. 2812201805. Preliminary identification followed by characterization of Acinetobacter species was done. Antibiotic susceptibility test was done using the Kirby-Bauer method following Clinical and Laboratory Standards Institute guidelines. Extended-spectrum Beta-Lactamase was detected by combined disc method and Biofilm detection was done using congo red agar method. Statistical Package for Social Sciences 16.0 version statistical software package was used for statistical analysis. Point estimate at 95% Confidence Interval was calculated along with frequencyand proportion for binarydata. RESULTS: Among 108 Acinetobacter species, 86 (79.7%) Acinetobacter calcoaceticus-A. baumannii complex was seen. Seventy-eight (72%) of the isolates were multidrug-resistant, 34 (31%) of the isolates were Extended-spectrum Beta-Lactamase producer and only 10 (9.3%) of the isolates, were biofilm producers. CONCLUSIONS: Multidrug-resistant Acinetobacter spp. with the ability to produce Extended-spectrum Beta-Lactamase is prevalent in our hospital settings. Strict compliance with infection control practices is necessary to curb its spread.
