Aim. To analyze the management of patients with associated complications from hypertension to improve prehospital therapeutic and diagnostic care. Materials and methods. The accounts and records (125,905 calling cards over 2012-2014) of the Statistics Division, Karaganda Regional First Aid Station, were used. The methods of clinical and mathematical analysis were applied. Results. There was an annual increase in the number of calls for all cases of hypertension complications in relation to the higher rate of hospitalization by 2014. The causes of non-100% hospitalization for life-threatening hypertension complications were revealed. Incomplete diagnostic data were one of the reasons for delayed diagnosis and development of prehospital complications from hypertension. When emergency care was rendered, differentiation therapy for hypertension complications was not always withstood; the use of drugs was noted to be unwarranted and contrary to the data of evidence-based medicine. Conclusion. The management of patients with associated complications from hypertension does not fully comply with the Diagnosis and Treatment Protocols of the Ministry of Health of the Republic of Kazakhstan.
