Introduction

Ensuring patient safety is not only an issue for anesthesiology. According to the World Health Organization's definition, patient safety means preventing potential harm to the patient and minimizing unnecessary harm during the provision of medical care [1].

The first public demonstration of anesthesia took place on October 16, 1846, but anesthesiology as a medical specialty developed in the second half of the twentieth century. The Copenhagen poliomyelitis epidemic of 1952 prompted major changes in respiratory support and intensive care. In 1953, Bjørn Aage Ibsen established a specialized intensive care unit in Copenhagen, an important milestone in the development of modern intensive care medicine [2, 3, 32].

To ensure high-quality anesthesiological and resuscitation care, doctors and nurses require appropriate professional training, a high level of life-support and monitoring technologies, and adequate provision of pharmaceuticals and medical equipment. According to W.L. Lanier, by 2000 global anesthesia-related mortality was approximately 1–2 cases per 200–300 thousand anesthetics [4], whereas in the 1960s–1970s it was approximately 1 case per 28 thousand anesthetics [5]. The development of anesthesiology and resuscitation, new technologies, and safer medications has contributed to a substantial decrease in anesthesia-related mortality.

Globally, cancer patients account for a substantial proportion of patients treated in anesthesiology, resuscitation, and intensive care settings [6]. In the United Kingdom, more than 200,000 adults and children are admitted to resuscitation and intensive care units annually [7]. Treatment costs have also risen; in the United States, critical-care expenditures increased markedly between 2000 and 2010 [8]. In Kazakhstan and worldwide, the increasing burden on anesthesiology, resuscitation, and intensive care departments is associated with the growing number of patients with cancer, as well as the increasing proportion of older patients and those with severe comorbidities [9].

Objective

To analyze the level and key determinants of anesthesiological care for the population, summarize international and Kazakhstan evidence on patient safety and service organization, and identify priority directions for improving staffing, equipment, professional training, standardization, and quality monitoring.

Scientific novelty

The novelty of this review lies in the integrated consideration of anesthesiological care as a system in which patient safety, workforce capacity, technical equipment, adherence to standards, audit, and organizational readiness are interdependent. The review brings together international evidence and Kazakhstan-specific regulatory and statistical data to formulate a structured set of dimensions for assessing the level of anesthesiological care and to identify areas requiring further national evaluation.

Materials and Methods

The work was conducted as a narrative analytical literature review with elements of secondary data synthesis. The analysis was based on the 33 bibliographic sources included in the original manuscript, comprising international scientific publications, professional and educational materials, official statistics, and regulatory documents related to anesthesiology, resuscitation, intensive care, patient safety, workforce capacity, and hospital organization.

The evidence was synthesized across five analytical domains: 1) patient safety and adverse-event prevention; 2) workforce availability and professional competence; 3) technical equipment and monitoring; 4) adherence to clinical standards and protocols; and 5) organizational capacity and accessibility of anesthesiological and intensive-care services. The manuscript does not provide a reproducible database search strategy, a specified search date, a PRISMA flow diagram, or formal quality assessment of the included sources; therefore, the work should be interpreted as a narrative analytical review rather than a systematic review or meta-analysis.

Results

Patient safety and quality of anesthesiological care

Adverse events in anesthesiology may reflect interactions between patient-related risk, equipment and organizational constraints, and clinical processes; systemic barriers to safety should therefore be considered alongside individual professional competence [1, 10, 17]. Important measures for reducing adverse events include performing diagnostic and therapeutic interventions in accordance with clinical recommendations, following established standards and protocols for anesthesia and intensive therapy, and conducting medical audits [10-14].

Over the past decades, specialists in anesthesiology and reanimatology have played an important role in medical research and patient-safety initiatives and have actively participated in implementing standards of medical care [1, 15, 17].

In the last two decades, the development of anesthesiology has been shaped by two broad trends: increased attention to patient and anesthesia safety and the wider use of surgical technologies that reduce the need for prolonged inpatient care and shorten preoperative and postoperative periods, alongside a natural increase in anesthesiologists' workload [18, 19, 20, 21].

Growing demand and organizational role of the service

Modern achievements in medicine, particularly surgery, are closely linked to the development of anesthesiology and resuscitation. At the end of the twentieth and beginning of the twenty-first century, the widespread introduction of modern anesthesiological and resuscitation technologies expanded the scope of surgical care and increased the number of patients with surgical, obstetric, and therapeutic conditions who could receive complex treatment [22].

The growing demand for anesthesiological and resuscitation care demonstrates that hospitals providing surgical care cannot function effectively without anesthesiology-resuscitation departments or teams. Demographic and macroeconomic trends indicate that demand for anesthesia services will continue to rise [23]. Anesthesiology, resuscitation, and intensive-care departments also operate in therapeutic hospitals, and their performance is linked to patient outcomes, hospital mortality, disability, temporary loss of working capacity, and healthcare costs.

One of the key factors influencing the work of hospital structural units is the increasing proportion of patients in severe condition and the share of emergency hospitalizations [24]. This increases the number of patients requiring emergency care and intensive therapy and strengthens the role of the anesthesiology and resuscitation service [25]. Reducing mortality in resuscitation units is an important reserve for reducing overall hospital mortality [26].

Kazakhstan context and workforce capacity

Kazakhstan's healthcare system is undergoing changes affecting both outpatient and inpatient care [27]. One direction has been the redistribution of bed capacity according to the intensity of treatment and care [28]. Such changes require review of the functional purpose and structure of hospitals and adaptation of their work to new conditions. This is particularly relevant for urban hospitals, where severely ill patients often require emergency care and intensive treatment. Anesthesiology and resuscitation departments play a critical role in these hospitals, and the volume of their work may increase in accordance with new organizational requirements [29].

Comparative analyses have identified differences in anesthesiology and intensive-care systems in Kazakhstan and abroad, including the level of training and experience of medical personnel. A global shortage of healthcare workers may exacerbate internal workforce imbalances, while rural areas often experience greater difficulties in attracting qualified personnel. International estimates underscore the scale of workforce shortages worldwide [30]. Kazakhstan workforce statistics for 2022 provide a basis for examining national staffing levels and regional distribution of specialists [29]. The precise number of anesthesiologists-resuscitators requires confirmation against the relevant table of the official statistical collection.

The available source material does not provide sufficient methodological information to substantiate a specific percentage of errors among deceased patients; consequently, this estimate is not used as evidence in the present review.

Kazakhstan has taken steps to develop anesthesiology and resuscitation through structural and quality-improvement measures. The Ministry of Health approved the Standard for the Organization of Anesthesiological and Resuscitation Care in the Republic of Kazakhstan by Order No. 78 of April 26, 2023 (registered No. 32409), subsequently amended, including amendments dated December 18, 2025 [33]. Professional education and resuscitation training should be discussed separately from the legal basis of this standard [21, 24].

Key criteria for assessing anesthesiological care

Quality of anesthesia and patient safety. One of the most important assessment dimensions is the prevention and reduction of postoperative complications, including pain, allergic reactions, and respiratory problems. The effectiveness of pain relief and reduction of complication risks depend on the anesthesiologist's qualifications and the anesthesia methods used [1, 18, 31].

Medical facility equipment. The availability of modern anesthesia equipment, real-time patient monitoring, and emergency resuscitation devices is essential for safe care. Equipment should be functional, adequately maintained, and consistent with contemporary clinical requirements [31, 33].

Professionalism of anesthesiologists. Professional competence includes the ability to assess the patient's condition, select an appropriate anesthesia strategy, anticipate risks, and respond to complications. Continuous professional development and regular training are necessary to maintain a high level of service [24, 31].

Adherence to standards and protocols. An important component of quality assessment is compliance with established standards and protocols during anesthesia and the postoperative period, with particular attention to prevention of complications and maintenance of a stable patient condition [1, 21, 31, 33].

Discussion

The reviewed evidence supports a systems perspective on anesthesiological care. Improvements in safety over recent decades have occurred alongside advances in specialist training, technology, pharmacotherapy, monitoring, standardization, and professional attention to patient safety. At the same time, growing numbers of older and high-risk patients and the increasing share of emergency care create additional demand for anesthesiology and intensive-care services.

For Kazakhstan, the key organizational issue is not only the absolute number of specialists but also their distribution, professional development, technical support, and integration into standardized clinical processes. National regulation and certification initiatives create a basis for further improvement, but meaningful assessment requires comparable indicators of staffing, equipment readiness, protocol adherence, adverse events, intensive-care outcomes, and regional accessibility.

The criteria described in the source material—patient safety, technical equipment, professional competence, and adherence to standards—can therefore be considered complementary dimensions of service quality rather than isolated characteristics. Their combined assessment may provide a more informative picture of the capacity of anesthesiology and resuscitation services.

Practical significance

For healthcare organizations, the review supports the use of a structured assessment framework that combines staffing ratios and qualification levels, availability and maintenance of anesthesia and monitoring equipment, compliance with protocols, regular clinical audit, continuing professional education, and monitoring of adverse events and outcomes. At the system level, regional comparison of these indicators may help identify areas with limited access and support more targeted workforce and infrastructure planning.

Limitations

The review is narrative and is based on sources that differ substantially in year of publication, population, healthcare setting, and study design. The original manuscript does not provide a reproducible search strategy or formal quality appraisal, and several numerical estimates refer to different countries or historical periods and therefore cannot be interpreted as directly representative of the current situation in Kazakhstan. A previously reported percentage of errors among deceased patients lacks sufficient methodological documentation to permit interpretation and has therefore been excluded from the substantive synthesis. These limitations restrict quantitative comparisons and causal interpretation.

Future research

Further research in Kazakhstan should use contemporary multicenter data to assess anesthesiology and intensive-care services by region and type of medical organization. Prospective audits should evaluate staffing and workload, equipment readiness, adherence to anesthesia and resuscitation protocols, adverse-event reporting, postoperative complications, intensive-care mortality, and patient-centered outcomes. Development of standardized national indicators would allow repeated monitoring and support evidence-based planning of anesthesiology services.

Conclusion

With the development of anesthesiology and resuscitation, requirements for the quality and safety of medical care have increased substantially. Patient safety remains relevant not only to anesthesiology but to all levels of medical care. International standards and protocols provide an important basis for further development of anesthesiological services.

Achievements in anesthesiology and resuscitation have contributed to a high level of anesthesia safety. Nevertheless, unresolved issues remain, including professional workforce development, regional availability of specialists, modernization and maintenance of medical equipment, standardized clinical processes, and further improvement of patient monitoring. Coordinated development of these components is necessary to strengthen the effectiveness and accessibility of anesthesiological care in Kazakhstan.
