Role of Mentzer Index for Differential Diagnosis of Iron Deficiency Anaemia and Beta Thalassemia Trait.

BACKGROUND: The most common differential diagnoses of microcytic hypochromic anaemia are iron deficiency anaemia and beta thalassemia. Globally, thalassemia affects approximately 4.4 out of every 10,000 live births whereas iron deficiency anaemia comprises half of all anaemia worldwide as per world health organization. The definitive diagnosis of beta thalassemia trait and iron deficiency anaemia requires haemoglobin analysis and iron studies respectively, which are not possible to perform in all suspected cases especially in resource limited settings. The study aims to evaluate the reliability of mentzer index in differentiating beta thalassemia trait from iron deficiency anaemia. METHODS: This was a cross sectional, observational study done on 59 patients each of beta thalassemia trait and iron deficiency anaemia from August 2019 to July 2020. Patients who were found to be having iron deficiency anaemia diagnosed by iron studies and beta thalassemia trait diagnosed by Hb electrophoresis were enrolled in the study using simple random sampling technique. RESULTS: Mentzer index correctly identified 95.76% of overall patients. Area under receiver operating characteristic curve was 0.993 (95% CI, 0.985-1.002, p<0.001). For beta thalassemia trait, mentzer index showed a sensitivity of 93.2%, specificity of 98.3%, positive predictive value of 98.2%, negative predictive value of 93.5%; while for iron deficiency anaemia, sensitivity of 98.3%, specificity of 93.2%, positive predictive value of 93.5% and negative predictive value of 98.2%. Youden's index was 91.5. CONCLUSIONS: The findings of the present study make mentzer index a reliable screening method, especially in a resource poor setting, like Nepal. Further confirmation by gold standard tests is recommended.

Prevalence and clinical impact of anemia in patients diagnosed with chronic obstructive pulmonary disease: A cross-sectional study.

Background and Aims: Unlike classically described polycythemia, anemia is found to be more prevalent in patients with chronic obstructive pulmonary disease (COPD). Anemia increases the cost of hospital stay and causes an increased risk of adverse outcomes including death in COPD patients. This study was done to find the prevalence of anemia in COPD patients, the factors associated, and the outcomes of anemic COPD. Methods: It was a quantitative, descriptive-analytical, and cross-sectional study conducted in Tribhuvan University Teaching Hospital's medical wards and the Emergency Room from September 2019 to September 2020. A simple random sampling method was used. Clinical information was obtained, and patients were followed up 3 months after discharge to document the number of exacerbations and deaths if present. Results: The patients in our study had a mean age of 70.80 ± 11.16 years. Most were female. Most (85.5%) had a history of exposure to firewood smoke. Twenty-three percent of the patients had anemia and these patients had significantly greater mortality 3 months postdischarge. Middle-old and old were more likely to have anemia with odds ratio (OR) of 2.55 (confidence interval [CI]: 0.48-13.5) and 13.6 (CI: 1.12-24.2), respectively. Current smokers had less likelihood of having anemia (OR: 0.05, CI: 0.006-0.49). Multivariate analysis showed that age, sex, and smoking status were significant determinants of anemia in COPD. There was no association between anemia and duration of hospital stay. However, mortality was higher at 3 months in COPD patients with anemia (p < 0.001). Conclusion: In COPD patients, anemia is prevalent comorbidity that is significantly linked to higher mortality but not to exacerbations. It is unknown, though, if treating anemia in COPD patients will affect the patient's outcome. Additional research in this area may be possible.

Utilization of Basic Health Services at Primary Health Care Facilities During COVID-19 Pandemic.

BACKGROUND: COVID-19, a novel rapidly emerging respiratory disease has spread across the world in a short span of time, infecting millions of people around the world. Consequently, health systems are overwhelmed by both direct mortality from COVID-19 and indirect mortality from other treatable conditions. Though COVID-19 prevention and control is crucial, it is also equally important to continue basic health services. Therefore, the study aimed to explore the facilitators and barriers of basic health service utilization at primary health facilities during the COVID-19 pandemic. METHODS: An exploratory qualitative study was conducted in the Bidur Municipality of Nuwakot district. Twenty-five telephone interviews were conducted from all the wards of the municipality and each lasted at least 20 minutes. The interviews were translated into English, coded using RQDA software, and analyzed using thematic analysis manually. RESULTS: The participants shared basic health service was interrupted during the pandemic, especially in the first month. However, the prominent factors that were often crosscutting to many factors were socio-economic conditions and fear of acquiring COVID-19. Additionally, inadequate personal protective equipment, mental stress, shortage of health workers, supplies disruptions, social stigma and extended lockdowns come into play for determining the utilization of basic health services during pandemic. CONCLUSIONS: Basic health service was heavily compromised during the pandemic. Fulfillment of the sanctioned posts, enhancement in the use of digital technologies can be promoting options for basic health service utilization during pandemic.

Guideline based knowledge and practice of physicians in the management of COPD in a low- to middle-income country.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is the third leading cause of death, with 80% of the total death occurring in low- to middle-income countries (LMICs). Nepal is one of the LMIC; COPD is a highly prevalent and significant public health issue often underdiagnosed. Medical physicians' good knowledge and practice to diagnose and treat COPD can help reduce the disease burden. OBJECTIVES: To determine the level of knowledge, practice and factors influencing the practice of physicians regarding COPD management based on GOLD guidelines. DESIGN: A cross-sectional descriptive study using a structured questionnaire was conducted among medical physicians working in Bagmati and Gandaki province of Nepal. Out of total scores, physicians knowledge and practice were graded according to Bloom's original cut-off point for good (≥80%), satisfactory (60%-78%) and poor (<60%). RESULT: A total of 152 medical physicians participated in this study. Out of the possible total score 20, the mean score on knowledge was 17.8 ± 2.4, and out of possible total score eight, the mean score on practice was 5.3 ± 1.3. The correlation test between total knowledge and practice scores showed r = 0.18 and p value <0.02. The most selected factors hindering the appropriate management of COPD was lack of patient follow up and lack of professional training in COPD. Other factors included patient unwillingness to discuss smoking quit plan, lack of screening tool, unavailability of spirometry and physician unawareness of available medicine to treat COPD. CONCLUSION: Despite physicians having good knowledge in COPD, the practice in COPD management is below guideline-recommended. There is a significant, very low positive correlation between total knowledge score and practice score. Proper COPD training to physicians, disease awareness among patients, easy availability of diagnostic equipment and medication can help improve physicians' practice and appropriately manage COPD patients.
