Consentimento informado. Expectativa. Procedimento cirrgico.

Objetivo: Analisar as informaes esperadas pelos pacientes/responsveis antes da assinatura do termo de consentimento de diferentes procedimentos otorrinolaringolgicos. Mtodos: Um total de 100 pacientes foram entrevistados atravs da utilizao de um questionrio padro antes de qualquer procedimento cirrgico no departamento de Otorrinolaringologia e Cirurgia de Cabea e Pescoo do Hospital Universitrio da Tribhuvan University entre setembro e novembro de 2006. Todas as questes foram respondidas de forma escrita. Os formulrios foram analisados utilizandose de mtodo manual simples usando freqncia e porcentagem. Resultados: A maioria (96.0%) dos pacientes ficou satisfeita com a informao dos mdicos assistentes sobre o procedimento cirrgico, antes de serem submetidos cirurgia. Entretanto, 8.0% dos entrevistados procuraram mais informaes atravs da internet, revistas e conversas com pacientes previamente operados. O tempo mdio de espera para cirurgia foi de 4.2 meses. Em torno de 77.0% dos pacientes no foram relatadas quaisquer complicaes. Informaes sobre qualquer complicao cirrgica conhecida foi solicitada por 90% dos pacientes. Concluso: As expectativas dos pacientes foram altas e a maioria procurou ser informada acerca de qualquer complicao cirrgica conhecida. Apesar do questionamento se o termo de consentimento deve conter todas as informaes sobre o procedimento cirrgico, o mesmo deve conter todas as principais complicaes cirrgicas.


Informed consent is the process of explaining a procedure and its risks, benefits and alternative treatments that allows patients to make educated decision about treatment. The amount of detail that is to be included in the informed consent process is inexact (1,2). Some states have enacted the "prudent patient standard," in which the physician must disclose all risks that a reasonably prudent patient would consider material to the decision to undergo or refuse a particular procedure (2,3,4). Other states support that a reasonably prudent physician would disclose to his or her patient (3,4). The purpose of this study is to asses the knowledge and information expected by patients/caretakers before signing consent form for different ENT surgical procedure.


This study was conducted in 100 patients undergoing elective surgery in ENT and head and neck surgery department at TU Teaching Hospital from September to November 2006.The mean waiting time from out patients booking to date of operation was also noted. All patients were interviewed with a standard questionnaire and all answered in written form. Questions include the knowledge of informed consent, frequency of complications that patients expected to know, sources of additional information regarding surgical procedure. These records were analyzed by simple manual analysis using frequency and percentage.


Results showed that 55.0% male and 45.0% female, children (18.0%), adults (82.0%). Thirty one percent patients were illiterate (Table-1). The mean waiting time for surgery was 4.2 months. The various types of surgical procedures were given in Table-2.

There were 96.0% patients satisfied with the information given by doctors about their surgical procedure before doing surgery. However 8.0% respondents looked for further information (source internets, various magazines, and talking to previously operated individuals.). Around 94.0% patients understand what inform consent is. There were 77.0% patients who could not list any complications. The most common complications listed by our patients were bleeding (8.0%) and wound infection (7.0%) (Table-3). However, 90.0% of patients expect to know all known complications.


The elements of informed consent include a description of the patient's condition and the treatment, the benefits of proposed treatment and the discussion of alternative treatment, including the implications of no treatment. Though majority of our patients were satisfied with the information given by doctors before surgery, 77.0% could not list even a single complications. Even after a relatively short time patients can have poor recall of information they have been given, and in elective surgery there can be a considerable time gap (3,5) between the date booked for surgery and operation day. In our study, we found low educational status, long time gap and less enthusiasm to search for further information regarding their surgery, as the factors that patient cannot give information properly. Only 8.0% of patients looked for further information regarding surgical procedure. But study by PAUL BURNS et al showed that two third of patients sought information elsewhere prior to signing their consent form (3). This showed that we need to increase the awareness and interest of our patients though patients' expectations had increased in recent times in developed countries. On asking what informed consent is almost all patient replied that they knew it. This was similar to other study (3).

Defining which risks are significant is arguably the most crucial aspect of informed consent law (3,6). Study by PAUL BURNS et al showed that 73.0% of those questioned expected to be informed of all known complications, even if the incidence was less than one percent. But our study had a different result. Almost all patients expected from doctors that all known complications should be informed.

Although most patients incorrectly believe that informed consent serves only to protect a physicians right the process of informed consent gives patients an understanding of a procedure (7). So that they can adequately make an informed decision. Mention extremely rare complication such as death would only serve to unjustly increase patient anxiety; however the argument that stating uncommon risks may cause undue patient anxiety has been disproved (7). When discussing complications with a patient, it is not clear whether one should present his or her incidence of a complication or that found in the literature. Though our patients wish to be informed all known complications, we should not miss major complications before surgery.


Patients' expectation was quite high and majority of them patients wanted to be informed about all known complications. Whether Informed consent should include all the informations regarding the surgical procedure is still debatable. However, it must include major complications after surgery.
