Background/Objectives: The implementation of advanced practice nursing in Kazakhstan is aimed at improving the accessibility and quality of primary healthcare. One of the key indicators of the effectiveness of this model is patient satisfaction, which reflects the perceived quality of care and directly influences treatment adherence. The aim of the study was to assess patient satisfaction with nurse-led consultations in primary healthcare institutions in Kazakhstan. Methods: A cross-sectional study was conducted using a questionnaire developed on the basis of Karin Bergman’s instrument and adapted to the Kazakhstani context. A total of 621 patients who attended independent nursing consultations in polyclinics in Aktobe, Almaty, Astana, and the village of Merke participated in the survey. Descriptive statistics and Pearson’s χ² test were applied, with statistical significance set at p < 0.05. Results: The majority of respondents were women, with a median age of 61 years. Awareness of independent consultations was higher among patients who regularly visited nurses (97.1% vs. 86.9%; p < 0.006). High satisfaction levels were associated with service accessibility, quality of examination, and clarity of recommendations. Among regular visitors, 99.2% reported satisfaction with the nurse’s work, and 76.6% rated the service as “excellent”. In contrast, patients with irregular visits more often reported dissatisfaction due to insufficient attention and limited knowledge of nurses. Conclusions: The findings confirm a high level of patient satisfaction with advanced practice nursing services and highlight the importance of this model in strengthening primary healthcare in Kazakhstan.

Background/Objectives: Chronic kidney disease (CKD) is a recognised risk factor for severe COVID-19, but comparative outcomes between conservatively managed CKD patients and those on maintenance haemodialysis (HD) remain incompletely characterised, particularly in Central Asia. This study evaluated the impact of CKD severity on clinical outcomes, inflammatory profiles, and mortality in hospitalised COVID-19 patients. Methods: This retrospective cohort study reviewed 891 patients hospitalised with COVID-19 at a tertiary infectious disease centre in Almaty, Kazakhstan, between 2020 and 2021. Patients were stratified into three groups: No CKD (n = 598), CKD without HD (n = 116), and CKD on maintenance HD (n = 177). Demographic, laboratory, treatment, and outcome data were extracted from electronic medical records. Multivariate logistic regression was used to identify independent predictors of in-hospital mortality, acute kidney injury (AKI), and intensive care unit (ICU) admission. Model 1 served as the primary prognostic model, while Model 2 explored in-hospital complications. Results: Patients with CKD exhibited significantly higher inflammatory markers, with peak C-reactive protein reaching 168.3 mg/L in the HD group compared to 44.4 mg/L in the No CKD group. In-hospital mortality was highest in the CKD without HD group (34.8%), followed by CKD on HD (21.7%) and No CKD (13.6%). AKI occurred in 35.7% of conservatively managed CKD patients. In multivariate analysis, CKD without HD independently predicted mortality (OR 3.23; 95% CI 1.38–7.63) and AKI (OR 4.12; 95% CI 1.73–10.03). Conversely, established HD status was not a significant independent predictor of mortality after adjusting for age and comorbidities. Conclusions: CKD severity strongly influences COVID-19 prognosis. Paradoxically, conservatively managed CKD patients carry a higher mortality and AKI risk than patients already on maintenance HD, which may be associated with the absence of scheduled volume and metabolic control, although causal inferences cannot be drawn from this observational data. These findings support the need for aggressive monitoring and early nephrological intervention in non-dialysis CKD patients hospitalised with severe viral respiratory infections.
