Surgical adverse events in audiovisual media: a documentary study

ABSTRACT

Objective

to analyze surgical adverse events reported by a Brazilian media.

Method

documentary and qualitative research. The source of information consisted of audiovisual reports on damages resulting from surgical interventions, reported in a Brazilian media. For searches on the electronic portal, those published until June 2019 were considered. Bardin's framework was used in the thematic analysis. The aforementioned incidents were classified according to the safety barriers contained in the Surgical Safety Checklist (SSC) of the World Health Organization.

Results

a total of 16 cases presented through 17 reports were analyzed. Of the total number of failures committed (n = 16), the majority (n = 13) could be prevented by checking items contained in the SSC. In the thematic analysis, three categories emerged: i. incident related to surgical intervention; ii. physical, psychological and socioeconomic resulting damage; iii. ethical-professional and/or legal consequences.

Conclusion and implications for the practice

the adverse surgical events disclosed by the reports greatly impacted on the lives of patients, in physical, emotional and socioeconomic aspects. They also brought implications for the professionals and health institutions involved. It is believed that the safety barriers contained in a globally recognized verification instrument are important tools to be used to promote the safety of surgical patients and save lives.

INTRODUCTION

Adverse events in perioperative care can be understood as injury or unintentional complication, resulting from an event or omission related to a procedure, care or health management not related to the patient's underlying disease, which can result in disability, prolonged hospital stay or mortality.11 World Health Organization. Conceptual framework for the international classification for patient safety [Internet]. Geneva: WHO; 2009 [citado 2020 maio 3]. Disponível em: http://www.who.int/patientsafety/taxonomy/icps_full_report.pdf
http://www.who.int/patientsafety/taxonom...

Data from the World Health Organization (WHO) show that postoperative complications occur in up to 25% of the patients and the mortality rate varies between 0.5% and 5%. In industrialized countries, at least half of the cases in which surgery led to harms, these were considered preventable. A contributing factor is that surgical safety measures are applied inconsistently, even in places with adequate infrastructure.22 World Health Organization. WHO surgical safety checklist implementation [Internet]. Geneva: WHO; 2009 [citado 2020 maio 3]. Disponível em: https://www.who.int/patientsafety/safesurgery/checklist_implementation/en/

In Brazil, there is a scarcity of studies that address the occurrence of adverse surgical events at the national level, since the existing ones portray only the local-regional reality.33 Moura ML, Mendes W. Avaliação de eventos adversos cirúrgicos em hospitais do Rio de Janeiro. Rev Bras Epidemiol. 2012 set;15(3):523-35. http://dx.doi.org/10.1590/S1415-790X2012000300007. PMid:23090300.

http://dx.doi.org/10.1590/1518-8345.2939...
The underreporting of these incidents by hospitals occurs because they have to deal with the exposure of flaws and weaknesses in the health care system and processes, which can contribute to the fact that these data are not sufficiently addressed in the available scientific publications.55 Alves MFT, Carvalho DS, Albuquerque GSC. Motivos para a não notificação de incidentes de segurança do paciente por profissionais de saúde: revisão integrativa. Ciênc. Saúde Colet (Barueri). 2019;24(8):2895-908. http://dx.doi.org/10.1590/1413-81232018248.23912017. PMid:31389537.
http://dx.doi.org/10.1590/1413-812320182...

In order to mitigate adverse surgical events and improve surgical patient safety, since 2009, the WHO recommends incorporating the Surgical Safety Checklist (SSC) in the operating room.22 World Health Organization. WHO surgical safety checklist implementation [Internet]. Geneva: WHO; 2009 [citado 2020 maio 3]. Disponível em: https://www.who.int/patientsafety/safesurgery/checklist_implementation/en/
https://www.who.int/patientsafety/safesu...
Since then, it has been gradually implemented by the hospitals.66 Weiser TG, Haynes AB. Ten years of the surgical safety checklist. Br J Surg. 2018;105(8):927-9. http://dx.doi.org/10.1002/bjs.10907. PMid:29770959.
http://dx.doi.org/10.1002/bjs.10907...
Despite this advance, it is believed that until there is a consolidation of the safety culture in the health services, when reporting adverse events related to health care, the media can contribute to the scientific community to develop research studies that seeks to understand the reasons for these failures and mitigation strategies.

In addition, the media can play a fundamental role in the debate and social mobilization in favor of building a culture of patient safety, because it exposes the dramatic reality of patients, arising from adverse surgical events and their implications and exerts and influence on the health system, not only with regard to seeking care, but in planning future medical interventions.77 Sudore RL, Landefeld CS, Pantilat SZ, Noyes KM, Schillinger D. Reach andimpact of a mass media event among vulnerable patients: the Terri Schiavo Story. J Gen Intern Med. 2008;23(11):1854-7. http://dx.doi.org/10.1007/s11606-008-0733-7. PMid:18716849.

http://dx.doi.org/10.1590/S0104-42302009...
Given the above, the present study aims to analyze the surgical adverse events reported by a Brazilian media.

METHOD

Descriptive and documentary research with a qualitative approach. In the study, reports from the G1 online news portal, linked to the Rede Globo television station, were used. This data source was chosen for being a free access website with major national and international repercussion.

In order to define the reports/articles, the search was carried out on the digital platform, by means of the locator available on the website's homepage (https://www.globo.com/), using the terms “surgical errors” and “error and surgery”, occurred in the Brazilian territory and reported in multimedia format, with written material and audiovisual production. It should be noted that, initially in the search process on the portal the keywords used were the following: “adverse events” and “surgical adverse events”; however, with these terms it was not possible to retrieve any reports. In view of this limitation, the terms used were those that contained the word “error”, despite the understanding that most of the recovered reports portray evidence of error and not error, as this refers to the deemed act. Time delimitation came from the search results, which defined it from 2012 to 2019. In addition, all the reports related to surgical adverse events with involvement (suspected or confirmed) of the multi-professional team – surgeon, anesthetist and nursing team – were considered.

Due to the limitations of search resources and ordering of the results found in this process, the reports were classified by themes and selected by reading the headline, eye and lead, which comprise the terms that designate the highlighted phrase and the first paragraph of the report, which answer the basic questions to keep the reader informed. Initially, 95 reports were found, and the description of the exclusions is shown in Figure 1.

Figure 1
Flowchart for the selection of the reports. Brazil, 2019

In the data collection stage, the following procedure was undertaken to allow the analysis: each of the 17 selected reports was watched several times to identify the speech of all the individuals involved and, thus, enable the complete transcription of the content. Subsequently, a spreadsheet was built to characterize each report in relation to the following variables: title, year of publication, location, health service involved, type of adverse event, characterization of the victims, professional category involved, outcomes, video, photo, length of the video and images released.

Each surgical adverse event was classified according to the safety barriers contained in the SSC proposed by the WHO as a way of preventing the adverse event, namely: safety barriers related to the period prior to anesthetic induction (entry), period prior to the surgical incision (surgical pause) and period immediately after closing the surgical incision (exit).22 World Health Organization. WHO surgical safety checklist implementation [Internet]. Geneva: WHO; 2009 [citado 2020 maio 3]. Disponível em: https://www.who.int/patientsafety/safesurgery/checklist_implementation/en/
https://www.who.int/patientsafety/safesu...

Then, the thematic analysis of the content of the reports was used according to Bardin's theoretical framework: 1) pre-analysis; 2) exploration of the material; and 3) inference and interpretation.99 Bardin L. Análise de conteúdo. São Paulo: Edições 70; 2016. In the pre-analysis stage, exhaustive readings of the content of reports were carried out in order to allow immersion in their content, allowing for greater apprehension of the whole presented. In the material exploration stage, the raw data were coded and transformed into meaningful information that gave rise to the registration units. Then, through thematic analysis, the nuclei of meaning were generated, considering their appearance and repetition. As the nuclei were brought together to approximate their meanings, the categories emerged, namely: i. Incident related to the surgical intervention; ii. Physical, psychological and socioeconomic resulting harms; iii. Ethical-professional and/or legal consequences. Finally, in the inference and interpretation stage, based on the speeches, the interpretations were elaborated.99 Bardin L. Análise de conteúdo. São Paulo: Edições 70; 2016. Additionally, in category one, the types of incidents were based on the conceptual framework for the international classification of patient safety.11 World Health Organization. Conceptual framework for the international classification for patient safety [Internet]. Geneva: WHO; 2009 [citado 2020 maio 3]. Disponível em: http://www.who.int/patientsafety/taxonomy/icps_full_report.pdf
http://www.who.int/patientsafety/taxonom...

Regarding the ethical aspects, as the information is contained in a public domain website, there was no need for a formal ethical review. As a guarantee of anonymity, the names of the victims and professionals were concealed in the data analysis, and the excerpts from the reports were coded by numbers.

RESULTS

Regarding the characterization of the reports, the cases were disclosed between 2012 and 2019. The victims covered the different life cycles, with predominance of adults (75.0%), eight women and four men. The news were more frequent in the Southeast (56.3%). The dissemination format included text, photos and videos, with the duration of the videos varying between 1'48” and 5'24”, totaling 39' and 18”, as shown in Table 1.

Table 1
Characterization of the reports on surgical adverse events published in a Brazilian media. Brazil, 2019.

Incident related to the surgical intervention

Regarding the first category of analysis, the types of incidents covered the following: a) Clinical process/procedure (n=14/cases 1 to 6 and 9 to 16), in which wrong procedure (n=2/cases 10 and 11), wrong side (n=2/cases 9 and 16), wrong place and identification not performed (n=1/case 1), not done when indicated – surgical items count (n=6/cases 2, 3, 6, 13 to 15)and inadequate (n=3/cases 4, 5 and 12) were involved; b) Medical devices/equipment (n=1/case 7), which involved failure/damage/malfunction; c) Nutrition (n=1/case 8), related to the wrong diet.

In addition, the types of incidents were related to the safety barriers contained in the SSC which, when used, contribute to the prevention of adverse events. Cases 4, 5 and 12 addressed the surgical adverse event related to the surgeon's imprudence, malpractice or negligence during the surgery. In these circumstances, the SSC safety barrier at the exit stage would provide the surgeon with an opportunity to review with the entire team essential concerns for the recovery and management of the patient, as shown in Box 1.

Physical, psychological and socioeconomic resulting harms

In this category, in all the cases analyzed (n=16), the surgical adverse event resulted in physical harm to the patients. The harms included intense pain, difficulty in eating, inability to move, bronchoaspiration, removal of a healthy organ and cardiopulmonary arrest, which required additional surgery and/or additional therapy (drug therapy, additional tests, intensive care to save lives, among others) or an increase in the length of hospital stay, and even the occurrence of death.

With the exception of four cases (1, 2, 7 and 15), the others (n=12) mentioned psychological harms such as suffering, impotence, pain due to loss and grief, sadness, nervousness, despair, disbelief, embarrassment, emotional exhaustion and outrage.

In addition, two cases (9 and 14) showed socioeconomic repercussions. These were characterized by the impossibility of returning to work and the cost of complementary treatment, which had a financial impact on the individual's life, as shown in Box 2.

Ethical-professional and/or legal consequences arising

In this category, the ethical-professional consequences (n=7/cases 1, 2, 3, 5, 6, 7, 8) consisted of diligences and acts that aimed at verifying the truth of facts alleged by the body of the medical council. And, in six cases (3, 6, 7, 8, 10, 12), the report mentioned that the hospital involved opened an administrative process (investigation) to investigate the functional infractions and institute penalties, if applicable.

In the legal aspect, a police report was filed (n=4/cases 1, 7, 9 and 12) to formalize the occurrence to the police authority. The opening of a police investigation took place in five cases (2, 3, 5, 7, 10) to ascertain the real truth of the allegedly criminal fact. The legal action process was mentioned in four cases (4, 13, 14 and 16), three cases (4, 13 and 16) are in progress and one (case 14) resulted in a judicial conviction where the sentence applied resulted in compensation to the victim. And, only one case (case 15) did not mention any legal referral, as shown in Box 3.

DISCUSSION

Surgical assistance is essential. However, according to the reports analyzed, the adverse surgical events that occurred showed an unsafe care practice, as it resulted in significant and sometimes irreversible harms to the patients and their families, in addition to consequences for the professionals involved and organizational outcomes.

In a study that aimed to know the experiences of victims of adverse events that occurred in health care and to understand how they faced the challenges imposed, the authors highlighted the patients' perplexity in finding themselves victims and the difficulty in accepting themselves as such, in addition to the physiological impact. The changes imposed by the adverse events led to behavioral and attitudinal changes, such as lack of confidence in the medical professionals. In addition, suffering and negative feelings become part of the experience of these people and suggest that it is necessary to create strategies that allow help and care for the mental health of people who have suffered harms.1010 Mendonça VS, Custódio EM. Nuances e desafios do erro médico no Brasil: as vítimas e seus olhares. Rev Bioet. 2016;24(1):136-46. http://dx.doi.org/10.1590/1983-80422016241115.
http://dx.doi.org/10.1590/1983-804220162...

Most of the surgical adverse events evidenced in the reports (n=12) consisted of inadvertent retention of items (n=6), followed by wrong procedure (cases 10 and 11) and wrong side (cases 9 and 16). It is noteworthy that, in the analysis based on safety barriers, the SSC is an important strategy for the prevention of surgical adverse events, which reinforces the importance of its use.

Similarly to the results obtained, surgical sentinel events analyzed between 2016 and 2019 point to the predominance of inadvertent retention of foreign bodies, followed by surgery in the wrong place, surgical and postoperative complications, wrong procedure and wrong patient.1111 The Join Commission. Sentinel events data: summary [Internet]. USA: Joint Commission; 2019 [citado 2020 maio 1]. Disponível em: https://www.jointcommission.org/resources/patient-safety-topics/sentinel-event/sentinel-event-data-summary/
https://www.jointcommission.org/resource...
In this perspective, verbal confirmation of the patient, of the procedure, and of the surgical site before anesthetic induction, provided in the SSC, is reinforced as a barrier against the occurrence of such adverse events. This must be performed verbally with the presence of the multidisciplinary team in the operating room, involving the patient in the process.22 World Health Organization. WHO surgical safety checklist implementation [Internet]. Geneva: WHO; 2009 [citado 2020 maio 3]. Disponível em: https://www.who.int/patientsafety/safesurgery/checklist_implementation/en/
https://www.who.int/patientsafety/safesu...

Another safe practice guided by protocols would be the safe demarcation of the limb, preferably while the patient has not yet received anesthetics to obtain verbal confirmation and thus involve the patient with their own safety. In this sense, it is clear that the implementation of SSC promotes the practice of safe surgery and presents itself as a tool for mitigating care failures.22 World Health Organization. WHO surgical safety checklist implementation [Internet]. Geneva: WHO; 2009 [citado 2020 maio 3]. Disponível em: https://www.who.int/patientsafety/safesurgery/checklist_implementation/en/
https://www.who.int/patientsafety/safesu...

In six cases, there was inadvertent retention of surgical items (gauze and compresses) in the patient's cavity. In this sense, a number of studies indicate an incidence between 0.15% and 0.2% of postoperative retention of foreign bodies, mainly in abdominal surgeries, which can generate major complications and risk to the patient's life, with mortality between 10% and 18%.1212 Amaral ALS, Borges O, Cordeiro AP, Matos RR. Corpo estranho intra-abdominal: relato de caso. Rev. Ciênc. Estud. Acad. Med. [Internet]. 2014; [citado 2020 maio 3];1:54-60. Disponível em: https://periodicos.unemat.br/index.php/revistamedicina/article/view/349
https://periodicos.unemat.br/index.php/r...

In order to avoid the occurrence of cases of material neglect in the patient's cavity, the literature suggests the classical method of counting the materials used in the surgical field at the beginning and at the end of the surgery. However, it is known that there is a possibility of failure during the counting of materials, as pointed out in an investigation that demonstrated that, in 88% of the cases of objects retained in the patients' cavities, there were reports in medical records that there was correct counting of the materials.1313 Gawande AA, Studdert DM, Orav EJ, Brennan TA, Zinner MJ. Risk factors for retained instruments and sponges after surgery. N Engl J Med. 2003;348(3):229-35. http://dx.doi.org/10.1056/NEJMsa021721. PMid:12529464.
http://dx.doi.org/10.1056/NEJMsa021721...
As a strategy to mitigate such failure, the WHO recommends that the surgeon should perform a methodical exploration of the wound before closing any anatomical cavity, although the procedure does not replace the process of counting the materials to be performed and recorded, involving different professionals, circulating, surgical scrubber and surgeon.22 World Health Organization. WHO surgical safety checklist implementation [Internet]. Geneva: WHO; 2009 [citado 2020 maio 3]. Disponível em: https://www.who.int/patientsafety/safesurgery/checklist_implementation/en/
https://www.who.int/patientsafety/safesu...

It should be noted that the beneficial potential of SSC for the safety of surgical patients is undeniable; however, in hospitals, the implementation of SSC is a complex and challenging process that requires the involvement of all health professionals responsible for patient care during the intraoperative period. This is because it requires the understanding that SSC is not a mere exercise in marking items and it is an instrument that aims to stimulate communication and teamwork, with the irreplaceable verbal checking of items among the participants. For successful implementation, there is a need for effective leadership, clear delegation of the responsibilities of each professional, collaboration among team members and institutional support by making available human and material resources necessary for daily use.1414 Tostes MFP, Galvão CM. Implementation process of the Surgical Safety Checklist: integrative review. Rev Lat Am Enfermagem. 2019;27:e3104. http://dx.doi.org/10.1590/1518-8345.2921.3104.
http://dx.doi.org/10.1590/1518-8345.2921...

Regarding the ethical-professional outcomes resulting from the surgical adverse event, a study conducted pointed to the fact that the accountability of the professionals must follow the ethical-legal procedures, but it must be remembered that there is an apparent blame for individuals without showing concern for the processes by which the failures are triggered, which denotes a wrong way of approaching the adverse event.1515 Souza VS, Inoue KC, Costa MAR, Oliveira JLC, Marcon SS, Matsuda LM. Nursing errors in the medication process: television electronic media analysis. Esc Anna Nery. 2018 maio 10;22(2):1-7. http://dx.doi.org/10.1590/2177-9465-ean-2017-0306.
http://dx.doi.org/10.1590/2177-9465-ean-...

In the legal aspect, similarly to the results, a documentary study characterized processes with judicial decisions (n=31) for errors involving Nursing professionals. In eight cases the victim died, in half of them, they had temporary disability (17=50%), and seven people had permanent disability. The most frequent error involved medication administration (38.71%), followed by childbirth assistance error (19.35%) and surgery (n=5; 16.13%), which included positioning of the cautery (burn) 3 (9.68%), material count (gauze in cavity) 1 (3.23%) and neglect of postoperative care 1 (3.23%). In more than half of the cases, the police report was filed by the victim himself. The professionals were convicted in 22 cases. The greatest number of convictions involved institutions, which justifies the participation/support of high institutional management and the search for self-preservation.1616 Souza VS, Inoue KC, Oliveira JLC, Freitas GF, Barlem JGT, Marcon SS et al. Desdobramentos judiciais do erro na enfermagem. Acta Paul Enferm. 2019;32(6):700-6. http://dx.doi.org/10.1590/1982-0194201900096.
http://dx.doi.org/10.1590/1982-019420190...

CONCLUSION AND IMPLICATIONS FOR THE PRACTICE

The surgical adverse events in the reports greatly impacted on the lives of the patients in physical, emotional and socioeconomic aspects. They also brought implications for the professionals and health institutions involved.

It should be noted that the analysis of the reports was restricted to those published in a Brazilian media; therefore, this reality is not representative of the country. In addition, the reports produced may have had their material edited. Thus, these are aspects that can represent a limitation for the study.

Despite this, this study can support the filling of a knowledge gap, as it allowed knowing the unacceptable existence of surgical adverse events from the perspective of some patients and family members who had their case disclosed in a media. In this context, the media is a relevant tool that gives voice to users of the Brazilian health system, exposing aspects of a dramatic reality of citizens who, when seeking surgical assistance to solve their health problem, felt the consequences of an unsafe service generating harms.

In addition, it is believed that, if the safety barriers contained in the SSC were strictly adopted in the clinical practice, most of the reported surgical adverse events could have been avoided. In this regard, it is hoped that this study may contribute for the health services to revisit their surgical care protocols, in order to ensure patient safety and save lives.
