Abstract

Pre-analytical errors represent a major source of inaccuracy in laboratory testing, contributing to approximately 70% of total diagnostic errors. At Fatmawati Hospital, prolonged patient waiting times within the laboratory workflow have emerged as a critical issue, adversely affecting both service quality and patient satisfaction. Lean Six Sigma (LSS) provides a structured methodology to systematically identify, analyze, and eliminate process inefficiencies and errors. This study aimed to apply the LSS framework to enhance the operational efficiency of pre-analytical laboratory services. An action research design was employed, utilizing the DMAIC (Define, Measure, Analyze, Improve, Control) model. Data collection methods included direct observation, structured interviews, and process audits, with subsequent analysis conducted using descriptive and inferential statistics. Implementation of LSS led to a statistically significant reduction in patient waiting times, decreasing from a mean of 129.13 minutes to 83.04 minutes — an improvement of 46.09 minutes or approximately 35.7%. This outcome was achieved through the elimination of non-value-added activities and the optimization of service pathways. In summary, the findings demonstrate that Lean Six Sigma is an effective approach for improving efficiency and service quality within pre-analytical laboratory operations. The results underscore the potential of LSS to serve as a transformative tool in laboratory process management.  Keywords: Lean Six Sigma, Waiting Time, Pre-analytical Process, Laboratory Services

Abstract

Intestinal protozoa infections are medical problems closely related to environmental hygiene and sanitation, which are sources of infection. This study aims to analyze the correlation between hygiene, environmental sanitation, and intestinal protozoan infections in toddlers residing in the Bantargebang TPST area of Bekasi City. The study is an observational analytical cross-sectional study conducted from March to May 2024 with 50 infant respondents accompanied by their parents, using purposive sampling. Data were collected from observations, interviews, and examinations of intestinal protozoan infections in fecal samples using the direct method. Data analysis was performed using the chi-squared test. The examination results showed that 28% were positive for intestinal protozoan infections, 44% had poor personal hygiene, and 48% had poor environmental sanitation. The Chi-Square test results indicated that there was no significant correlation between hygiene and intestinal protozoan infection in infants (P = 0.243) and no significant correlation between environmental sanitation and intestinal protozoan infection in infants (P = 0.420). The researchers concluded that there was no significant correlation between hygiene and environmental sanitation and intestinal protozoan infections experienced by toddlers around the Bantargebang TPST in Bekasi City. The researchers suggested finding research locations with high prevalence and researching other factors that may influence intestinal protozoan infections.

Abstract

Antibodi Immunoglobulin E (IgE) dibuat oleh sel B dan sel plasma sebagai respon terhadap stimulasi antigenik dan berfungsi dalam mekanisme reaksi alergi. Pemeriksaan Atopy IgE Panel Indonesia merupakan tes semi kuantitatif untuk mendeteksi antibodi manusia terhadap alergen dalam darah. Tungau debu rumah (TDR) berperan sebagai sumber alergen dermatitis atopik (DA). Tujuan dari penelitian ini adalah untuk menentukan gambaran kadar IgE Atopy TDR pada pasien DA yang melakukan pemeriksaan di Laboratorium LiderLab, Kota Bekasi, Jawa Barat. Penelitian deskriptif ini menggunakan metode potong lintang. Dalam penelitian yang dilakukan pada 48 pasien dengan diagnosis DA yang melakukan pemeriksaan IgE Atopy berdasarkan resume dokter, ditemukan bahwa jenis kelamin perempuan sebanyak 52,08% dan laki-laki sebanyak 47.92%, kelompok usia terbesar adalah 6-11 tahun sebanyak 18,75%, memiliki riwayat atopik genetik sebanyak 58,33% dan rentang rerata kadar IgEnya 38,47–42,99 KU/l dari 3 spesies tungau yaitu D. pteronyssinus, D.farinae, dan D.microceras. Simpulan dalam penelitian ini adalah kadar IgE tertinggi berasal spesies D.pteronyssinus yang masuk klasifikasi IgE Klas 5 dengan kadar 50 – 100 KU/L. Pada pasien DA disarankan membersihan lingkungan rumah secara rutin dengan menggunakan alat penyedot debu.

Abstract

Background: Dengue remains a significant health problem in Indonesia, including Batam. Because its symptoms resemble other infections, early laboratory testing is crucial. The non-structural protein one rapid diagnostic test (NS1 RDT) is widely used, but its accuracy depends on the day of illness, immune status, and viral serotype.Objective: To evaluate the diagnostic validity of NS1 RDT compared to RT-PCR, assessing the level of agreement between the two methods, and analysing the influence of clinical phase and serotype on the results of the examination.Methods: A retrospective analytic study used secondary data from 309 suspected dengue cases tested by NS1 RDT at primary care and confirmed by RT-PCR with serotyping at Batam Public Health Laboratory (2022–2024). Diagnostic performance was calculated from 2×2 tables; concordance was analysed with McNemar's test and Cohen's kappa.Results: The NS1 RDT showed 75.8% sensitivity, 81.2% specificity, 62.7% positive predictive value, 88.9% negative predictive value, and 79.6% overall accuracy, with moderate agreement with RT-PCR (κ = 0.54). NS1 positivity peaked on illness days 1–3 and varied by serotype, with the highest for DENV-3.Conclusions: The NS1 RDT showed good diagnostic validity with moderate agreement and sensitivity and high specificity in early dengue disease screening compared to RT-PCR, so the diagnostic performance of the NS1 RDT can be used in local epidemiological testing in Batam.
