My dad is 87 years old, so there are some age-related health problems, in particular high blood pressure. It was necessary to choose a drug that not only reduces blood pressure, but also keeps it stable. It was possible to do this in the # 1 polyclinic, but it was necessary to monitor the indicators and gradually change the dose and make adjustments to the treatment. I found it more convenient to put Dad in this hospital and pick up supportive medications under the supervision of a doctor. In addition, at this age, it is not superfluous to undergo a check-up (medical examination in our Soviet language). As a result, the drug was picked up, dad was additionally treated, all sorts of studies were done , he hung out with his grandparents, they told each other what, where and how they hurt. In the end, everyone is happy.
A serious part of the recommendations is that it is convenient that all (or almost all) laboratory tests can be performed in one place.
