title: CKF in a Haitian hospital data.xlsx

description: This is data from the Nephrology Department of the State University Hospital of Haiti (HUEH). The study population included all patients diagnosed with CKF at HUEH or elsewhere, who are followed in the Nephrology Department from January 2015 to September 2019. The study population was selected according to these criteria: <em>Inclusion criteria</em> -Patients diagnosed with CKF at HUEH or elsewhere and who are monitored in the dialysis unit during the study period. -Patients with CKF diagnostic laboratory tests in their file, including at least: a high creatinemia and/or a high blood urea level and/or an ultrasound with abnormalities, and/or a renal biopsy with fibrosis. <em>Exclusion criteria</em> -Patients with incomplete medical records i.e., not including age, sex, reasons for consultation, and clinical signs simultaneously. An individual collection sheet was prepared in Epi Info 7. All the data collected was well saved without any personal information that could reveal the patients' identity. We defined the year of admission as the year of the patient's first consultation in the department during the study period. Age is noted as mentioned in the file, measured in completed years (exact age), and then categorized ​​(age groups). Sex is determined on the male and female dichotomous scale. The provenance is measured according to the department where the person resides among the 10 in the country. Occupation is defined as the regular activity conducted by the patient to earn a living. Those activities can be regarded as professions such as trader, teacher, nurse, engineer, mason, and plumber...These socio-demographic data are taken from the first record recorded for the patient. The reasons for consultation, clinical signs, history, and associated pathologies are noted as mentioned in the first consultation form. The etiology of CKF is known from the diagnosis. We determined the stage of the CKF of each patient from the glomerular filtration rate which is calculated thanks to the application of Medscape from the serum creatinine level according to the MDRD equation: Moderate stage (30-59ml / min /1.73m²); Severe stage (15-29 ml/min / 1.73m²); Terminal stage (Creatinine clearance &lt;15ml / min / 1.73m²). For the data of the paraclinical examinations, we considered the results of the first examinations reported by the patients after the first consultation. The dosage of creatinemia, the normal value of which is between 0.9 and 1.3 mg/dl. The hemoglobin level was used to diagnose anemia if it was less than 12 g/dl in women and less than or equal to 13 g/dl in men. We speak of severe anemia when the hemoglobin level is less than 8g/dl. The dosage of urea nitrogen with a normal value between 7 and 20 mg/dl. Calcemia with a normal value of 8.7 to 10.4 mg/dl. There is hypocalcemia below 8.7 mg/dl and hypercalcemia above 10.4 mg/dl. Phosphoremia with a normal value: 2.5-4.8 mg/dl. There is hypophosphatemia below 2.5 mg/dl and hyperphosphatemia above 4.8 mg/dl. The data from the renal ultrasound are taken from the conclusions of the operator who performed it on the size, echostructure of the kidneys, and cortico-medullary differentiation. Examination of urine for the presence of leukocyturia, hematuria, proteinuria. For complications, we noted all the information from the patient follow-up sheets. The data on the prescribed treatment is taken from the follow-up sheet closest to the first consultation: antihypertensive agent to control high blood pressure is measured according to the number of drugs prescribed and the antihypertensive drugs class: ACE inhibitors, diuretics, calcium channel blockers, ARBs, Vasodilators, Beta-blockers; Antianemic treatment to correct anemia is measured according to 3 modalities (iron, blood transfusion, EPO). The outcome of patients is measured according to 4 methods (Abandonment, followed elsewhere, deceased, dialysis). We noted information directly on the coverage of files as for cases of abandonment, death, and followed elsewhere, we noted the patients who are still on hemodialysis during blood collection using the list available at the Nephrology Department. The data are entered in Excel and processed by Epi Info 7 and SPSS software 20. Qualitative variables are measured by frequency and percentage calculations and quantitative variables by measures of central tendency (mean, median) and quartiles for some. As the distribution of our data was not normal, we used the nonparametric Kruskal-Wallis test to compare the mean of age as a function of the etiology and the means of serum creatinine level and urea nitrogen level as a function of the stage of CKF then as a function of the etiology having more than two modalities with p-value &lt;0.05 as the significance level. Fisher's exact test was used for qualitative variables: urine analysis (leukocyturia) and stage of CKF, etiology of CKF and associated history and pathologies (hypertension and diabetes), etiology of CKF, and gender.
