INTRODUCTION

Delirium is a neurological disorder that leads to changes in consciousness and attention levels, cognitive deficits and disorientation, with an acute onset and a fluctuating course11. Ely EW, Margolin R, Francis J, May L, Truman B, Dittus R, et al. Evaluation of delirium in critically ill patients: validation of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU).

https://doi.org/10.1097/00003246-2001070...
. This clinical condition has a high incidence in critically ill patients, ranging from 18.9% to 68.3% in Intensive Care Units (ICU), and those submitted to mechanical ventilation may be more affected11. Ely EW, Margolin R, Francis J, May L, Truman B, Dittus R, et al.

.

Other outcomes may be associated with patients with delirium in the ICU, such as increased morbidity and mortality, length of hospital stay and mechanical ventilation, in addition to a decline in functionality11.

. Due to its fluctuating course, this dysfunction is not diagnosed or treated in a systematic or appropriate way in health services44.

.

The diagnosis of delirium is made at the bedside by a clinical examination and by any trained professional, mostly nurses, through the use of validated tools. The most commonly used tool in the ICU is the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU)22. Wan RYY, McKenzie CA, Taylor D, Camporota L, Ostermann M. Acute kidney injury as a risk factor of hyperactive delirium: a case control study. J Crit Care. 2020;55:194-7. doi: https://doi.org/10.1016/j.jcrc.2019.10.013

https://doi.org/10.5935/0103-507X.201500...
. In 2011, a multicenter study was developed to validate the CAM-ICU in Brazil, since it was already widely used in clinical practice. The results showed high specificity (96.2%), good sensitivity (72.5%), in addition to good predictive power when the scale is used systematically66. Gusmão-Flores DG, Salluh JIF, Dal-Pizzol F, Ritter C, Tomasi CD, Lima MASD, et al. The validity and reliability of the Portuguese versions of three tools used to diagnose delirium in critically ill patients. Clinics. 2011;66(11):1917-22. doi: https://doi.org/10.1590/S1807-59322011001100011
https://doi.org/10.1590/S1807-5932201100...
. This scale can be used by nurses for the diagnosis of delirium, which is a condition associated with the Nursing Diagnosis (ND) of Acute Confusion88. Herdman HT, Kamitsuru S, editors. NANDA International Nursing Diagnoses: definitions and classification 2018-2020. 11th ed. New York: Thieme; 2018., which can be frequently found in ICUs due to the high incidence of delirium.

In clinical practice, once an accurate ND of Acute Confusion is established, the most appropriate Nursing Interventions can be carried out88. Herdman HT, Kamitsuru S, editors. NANDA International Nursing Diagnoses: definitions and classification 2018-2020. 11th ed. New York: Thieme; 2018.) in order to obtain the expected results. It is in this setting that the use of care protocols is recognized as important, since, based on the best evidence, the professionals can guide the care for patients with delirium.

The relevance of this study is due to the high incidence of delirium in the ICU, which can determine a worse clinical outcome. There is still a lack of consensus regarding effective care for delirium, since pharmacological interventions are not efficient in the prevention and/or treatment of delirium99. van den Boogaard M, Slooter AJC, Brüggemann RJM, Schoonhoven L, Beishuizen A, Vermeijden JW, et al. Effect of haloperidol on survival among critically ill adults with a high risk of delirium: the REDUCE randomized clinical trial. JAMA. 2018;319(7):680-90. doi: https://doi.org/10.1001/jama.2018.0160
https://doi.org/10.1001/jama.2018.0160...
, while non-pharmacological and multiprofessional strategies show better results1010. Bounds RN, Kram S, Speroni KG, Brice K, Luschinski MA, Harte S, et al. Effect of ABCDE bundle implementation on prevalence of delirium in intensive care unit patients. Am J Crit Care. 2016;25(6):535-44. doi: https://doi.org/10.4037/ajcc2016209

https://doi.org/10.1097/CCM.000000000000...
. Therefore, this research seeks to answer the following question: What care should be part of a multiprofessional care protocol to be implemented for critically ill patients with delirium?

METHOD

This is a methodological study consisting in the content validation of a multidisciplinary care protocol. The validation process happens in two stages1212. Santos EC, Oliveira ICM, Feijão AR. Validation of a nursing care protocol for patients undergoing palliative care. Acta Paul Enferm. 2016;29(4):363-73. doi: https://doi.org/10.1590/1982-0194201600051
https://doi.org/10.1590/1982-01942016000...
. In this study, the first was the elaboration of the protocol by cross-mapping the interventions proposed by the Nursing Intervention Classification (NIC)1313. Bulechek GM, Butcher HK, Dochterman JM. Classificação das Intervenções de Enfermagem (NIC). 6. ed. Rio de Janeiro: Elsevier; 2016. for the ND of Acute Confusion, related to delirium, and which, since the current edition of NANDA-I88. Herdman HT, Kamitsuru S, editors. NANDA International Nursing Diagnoses: definitions and classification 2018-2020. 11th ed. New York: Thieme; 2018., started to be considered a condition associated with this diagnosis, instead of a factor related with the care found from an integrative review. Thus, a correlation by similarity was established between the care for delirium from the scientific literature and the standardized language of the NIC, standardizing and validating each recommendation of care found in order to build the protocol. It should be noted that the NIC is a taxonomic structure that can be used by health professionals1313. Bulechek GM, Butcher HK, Dochterman JM. Classificação das Intervenções de Enfermagem (NIC). 6. ed. Rio de Janeiro: Elsevier; 2016..

Regarding the sample, studies suggest three to 42 participants for a validation study1212. Santos EC, Oliveira ICM, Feijão AR. Validation of a nursing care protocol for patients undergoing palliative care. Acta Paul Enferm. 2016;29(4):363-73. doi: https://doi.org/10.1590/1982-0194201600051

https://doi.org/10.1002/nur.20147 ...
. In order to obtain consistent results, 60 professionals were invited to participate in the research. These participants were defined by the network sampling strategy, in which the initial members of the sample indicate other individuals1414. Machado RC, Gironés P, Souza AR, Moreira RSL, Jakitsch CBV, Branco JNR. Nursing care protocol for patients with a ventricular assist device. Rev Bras Enferm. 2017;70(2):353-9. doi: https://doi.org/10.1590/0034-7167-2016-0363
https://doi.org/10.1590/0034-7167-2016-0...
. The initial identification of these professionals was made through the Lattes Platform, considering authors with scientific publications on delirium. The professionals were selected following at least one of these inclusion criteria: having clinical experience in an adult ICU of at least two years and/or being an expert in Intensive Care. Professionals from the South and Southeast regions of Brazil were invited.

After the selection, participants were approached via email. An explanatory e-mail was sent explaining the aim of the study, methods used, and the instrument for validating the protocol. A response was considered as a positive return and, thus, confidentiality was guaranteed. The deadline for the return was 30 days and, after this period, a new contact was made in order to increase the number of participants. The type of care present in the protocol was evaluated only once by each professional. The data collection period was from August 2016 to January 2017.

The results of the assessments, initially and for the purposes of this discussion, were presented through a descriptive analysis categorized by professional categories: nurses, physical therapists, physicians and others (nutritionists, pharmacists, and psychologists). In the assessment by professional category, percentages of ≥70% were found to be indicative of agreement1212. Santos EC, Oliveira ICM, Feijão AR. Validation of a nursing care protocol for patients undergoing palliative care. Acta Paul Enferm. 2016;29(4):363-73. doi: https://doi.org/10.1590/1982-0194201600051
https://doi.org/10.1590/1982-01942016000...
.

For the validation process, the Content Validity Index (CVI) was considered, which is widely used in the health area and measures the proportion of the recommendations of the protocol elements1212. Santos EC, Oliveira ICM, Feijão AR. Validation of a nursing care protocol for patients undergoing palliative care. Acta Paul Enferm. 2016;29(4):363-73. doi: https://doi.org/10.1590/1982-0194201600051

https://doi.org/10.1002/nur.20147 ...
. The CVI uses the following values for the responses, adapted for this study: 1 for "I do not recommend" and 4 for "I recommend". This method is calculated by the sum of the items that were evaluated as “recommend” - that is, with a score of 4 - using the following formula1515. Polit DF, Beck CT. The content validity index: are you sure you know what’s being reported? Critique and recommendations. Res Nurs Health. 2006;29(5):489-97. doi: https://doi.org/10.1002/nur.20147

Since this is a multidisciplinary protocol, the establishment of consensus and the consequent inclusion of a recommendation in the protocol were reached when the CVI was ≥ 0.90.

The research was developed in accordance with the guidelines and standards established by Resolution 466/12 of the National Health Council. It was sent to the Research Committee of the School of Nursing and to the Ethics and Research Committee of the Universidade Federal do Rio Grande do Sul, having been approved under protocol number 1.526.221.

RESULTS

The validation process counted on the participation of 43 professionals, 19 nurses (44.2%), 10 doctors (23.3%), eight physical therapists (18.6%), two pharmacists (4.7%), two psychologists (4.7%), and two nutritionists (4.7%). Most professionals were female (62.8%), with an mean age of 34.51±4.29 years and a mean of 7.5 years of experience in the ICU. All were post-graduates, 20 were specialists in Intensive Care (46.6%), and 13 had master's degrees (30.2%). Most worked in assistance (81.4%).

For the protocol validation process, the care was organized according to the following tables, with the CVI shown in the last column. Table 1 presents a diagnosis of delirium, pain management, sedation pause and administration of antipsychotics.

Of the 48 care recommendations submitted to validation, only four did not reach the consensus established by the CVI ≥0.90 and, therefore, were not recommended to compose the protocol (as shown in the Attachment). The non-validated recommendations were: “Performing spontaneous ventilation tests”, “Using opioid as the drug of choice for the treatment of pain”, “Not arresting mechanical restraints to the bed” and “Providing 90 minutes of quiet time twice a day”.

DISCUSSION

When analyzing the content validity, the results obtained by calculating the CVI recommended most of the recommendations proposed by this study, thus totaling 44 recommendations to compose the multiprofessional care protocol. During the assessment by professional category, there were some differences in agreement, which can identify different levels of knowledge about delirium.

The diagnosis of delirium is usually made by applying the CAM-ICU by any trained professional. However, despite being a validated diagnostic tool developed 15 years ago22. Wan RYY, McKenzie CA, Taylor D, Camporota L, Ostermann M. Acute kidney injury as a risk factor of hyperactive delirium: a case control study. J Crit Care. 2020;55:194-7. doi: https://doi.org/10.1016/j.jcrc.2019.10.013
https://doi.org/10.1016/j.jcrc.2019.10.0...
,66. Gusmão-Flores DG, Salluh JIF, Dal-Pizzol F, Ritter C, Tomasi CD, Lima MASD, et al. The validity and reliability of the Portuguese versions of three tools used to diagnose delirium in critically ill patients. Clinics. 2011;66(11):1917-22. doi: https://doi.org/10.1590/S1807-59322011001100011
https://doi.org/10.1590/S1807-5932201100...
, the adherence by the multidisciplinary team still needs to improve. The systematic evaluation of delirium by medical professionals, physical therapists and nurses in Latin America and Europe, identified in a previous study, showed that CAM-ICU was the most used (66.9%) instrument, being significantly more used in Brazil compared to the other countries (83% vs 43.5%, P <0.001)77. Tanaka LMS, Salluh JIF, Dal-Pizzol F, Barreto BB, Zantieff R, Tobar E, et al. Delirium in intensive care unit patients under noninvasive ventilation: a multinational survey. Rev Bras Ter Intensiva. 2015;27(4):360-8. doi: https://doi.org/10.5935/0103-507X.20150061
https://doi.org/10.5935/0103-507X.201500...
.

The aforementioned results converge with the evidence of this study in relation to the use of CAM-ICU for the diagnosis of delirium, recommending and reiterating its importance in clinical practice. However, the knowledge and use of this tool requires a better understanding of all professional categories that work in the ICU. Predominantly, CAM-ICU is used in the ICU by trained nurses and can be a tool for diagnostic reasoning.

In the current edition of NANDA-I88. Herdman HT, Kamitsuru S, editors. NANDA International Nursing Diagnoses: definitions and classification 2018-2020. 11th ed. New York: Thieme; 2018., delirium is an associated condition of the ND Acute Confusion, despite being treated by a multiprofessional team. This new categorization can be contested, since the nurse has both independent actions and those shared with the multiprofessional team, both for the prevention and treatment of delirium.

The implementation of multiprofessional care is highlighted in studies. A cohort of 70 patients demonstrated the benefits of interventions for pain, agitation and delirium by developing guidelines with a pharmaceutical professional. In a second phase, sedation pause, spontaneous ventilation tests and early mobilization were incorporated. 436 patients were followed up prospectively. The results of the first phase showed a reduction in sedoanalgesia (P = 0.001) and length of stay in the ICU (P = 0.01), while in the second phase, a reduction was observed in the length of mechanical ventilation (P = 0.03) and in mortality (P = 0.01)1616. Louzon P, Jennings H, Ali M, Kraisinger M. Impact of pharmacist management of pain, agitation, and delirium in the intensive care unit through participation in multidisciplinary bundle rounds. Am J Health Syst Pharm. 2017;74(4):253-62. doi: https://doi.org/10.2146/ajhp150942
https://doi.org/10.2146/ajhp150942...
. Such findings corroborate the results found in this study: care related to sedation pauses and early mobilization was recommended in order to obtain better outcomes by the assistance provided. Thus, delirium is treated with feasible, multi-professional and not pharmacological actions - associating the care of the nursing team with those of physical therapy - possibly reducing risk factors.

Another retrospective study demonstrated the benefits of incorporating care related to awakening the patient and coordinating spontaneous ventilation tests, monitoring for delirium and early mobilization. 159 ICU patient records were analyzed, and it was observed that the prevalence of delirium decreased significantly (38% vs 23%, P = 0.01) and that there was a reduction in the mean number of days in delirium (3.8 to 1.72 days, P <0.001)1010. Bounds RN, Kram S, Speroni KG, Brice K, Luschinski MA, Harte S, et al. Effect of ABCDE bundle implementation on prevalence of delirium in intensive care unit patients. Am J Crit Care. 2016;25(6):535-44. doi: https://doi.org/10.4037/ajcc2016209
https://doi.org/10.4037/ajcc2016209...
. Thus, the established consensus is emphasized, since it seems to be effective in the management of delirium, in addition to improving other clinical outcomes.

Early mobilization was a recommendation considered relevant for the critical patient with delirium. In this context, it is worth mentioning the importance of the participation of the entire multidisciplinary team during the mobilization process, from the moment of the assessment of the patient's clinical conditions to the execution of the procedure, which becomes very complex in the context of Intensive Care. A multicenter randomized clinical study, involving 200 patients, developed an early mobilization protocol by goals: no mobilization, passive movements in the bed, standing up and walking. In the intervention group, patients had more days free of delirium compared to the control group (25 vs 22 days, P = 0.01), demonstrating the efficiency of mobilization for the management of delirium1717. Schaller SJ, Antey M, Blobner M, Edrich T, Grabitz SD, Gradwohl-Matis I, et al. Early, goal-directed mobilisation in the surgical intensive care unit: a randomised controlled trial. Lancet. 2016;388(10052):1377-88. doi: https://doi.org/10.1016/S0140-6736(16)31637-3
https://doi.org/10.1016/S0140-6736(16)31...
. This evidence supports and directs the development of care protocols, encouraging early mobilization in critically ill patients with delirium, despite some difficulties encountered in clinical practice, such as infrastructure problems and work demands. In this context, the multiprofessional team needs to be engaged to safely mobilize the patient, avoiding possible adverse events, and to be aware of the benefits and the best results for the patient.

Likewise, in order to increase the quality of care, recommendations directed at pain management, agitation and delirium1818. Barr J, Fraser GL, Puntillo K, Ely EW, Gélinas C, Dasta JF, et al. Clinical practice guidelines for the management of pain, agitation, and delirium in adult patients in the intensive care unit: executive summary. Am J Health Syst Pharm. 2013;70(1):53-8. doi: https://doi.org/10.1093/ajhp/70.1.53
https://doi.org/10.1093/ajhp/70.1.53 ...
were mostly approved to compose the protocol. Pain assessments using the Critical Care Pain Observation Tool scale was applied in a study with 106 intensive care nurses. The results showed that, after an educational intervention, the professionals were more favorable to use of the scale (22.6% vs 53.8%, P <0.001), in addition to developing more adequate analgesic management1919. Asadi-Noghabi AA, Gholizadeh M, Zolfaghari M, Mehran A, Sohrabi M. Nurses use of critical care pain observational tool in patients with low consciousness. Oman Med J. 2015;30(4):276-82. doi: https://doi.org/10.5001/omj.2015.55
https://doi.org/10.5001/omj.2015.55 ...
. Thus, the need to adequately assess and treat pain is important so that it does not lead to increased agitation and, possibly, delirium.

The treatment with haloperidol presented with divergences in this study, as well as in scientific literature. The literature shows no evidence to justify the routine use of antipsychotics for the management of delirium99. van den Boogaard M, Slooter AJC, Brüggemann RJM, Schoonhoven L, Beishuizen A, Vermeijden JW, et al.

. However, it is worth mentioning that, in a situation of acute agitation, there may be an indication for the use of this medication. The use of haloperidol was reiterated by the physicians who participated in this study, since they considered this recommendation to be relevant. This was also demonstrated in a multiprofessional survey of physicians, physical therapists and nurses, in which haloperidol was the most frequently chosen drug (65.5%) for the control of delirium77.

. In an attempt to corroborate the recommendation of pharmacological management with haloperidol in critically ill patients with delirium, the results of a systematic review were conflicting in relation to the use of antipsychotics. The authors state that, even without strong evidence, haloperidol remains the drug of choice for the treatment of delirium2020.

The recommendations to promote sleep, such as the one for the provision of ear protectors and eye masks, showed some divergences in the assessments by the professionals. This may be related to the different realities found in Brazilian ICUs and to the many and diverse difficulties faced in clinical practice and may even reflect the resistance to the incorporation of new care and technologies. However, there was a consensus with regard to this recommendation, meaning it was considered relevant in the multiprofessional protocol, since sleep interruption is a risk factor for the development of delirium1818. Barr J, Fraser GL, Puntillo K, Ely EW, Gélinas C, Dasta JF, et al. Clinical practice guidelines for the management of pain, agitation, and delirium in adult patients in the intensive care unit: executive summary. Am J Health Syst Pharm. 2013;70(1):53-8. doi: https://doi.org/10.1093/ajhp/70.1.53

.

Regarding interventions related to cognitive orientation, all of them reached a consensus, with no doubts as to their indication. Since they are easy to implement and do not require a great deal of financial and structural involvement, they require only a trained and committed team in the development of activities. Most reorientation care is already randomly performed by health professionals in the Intensive Care environment.

Finally, it is known whether the presence of the family in the ICU in extended visits can decrease the occurrence of delirium and the length of stay of patients33.

https://doi.org/10.1097/CCM.000000000000...
, improving clinical outcomes. The recommendation related to the presence of family members was also approved in this study, as health professionals understand the relevance of the family in qualified and humanized care.

All the professionals who are part of the multiprofessional team must make their decisions using the best evidence, carrying out their functions with clarity and precision. This can be guaranteed by multiprofessional rounds or in conversations at the bedside, listing the activities that will be developed and establishing aims for the attention. Currently, nurses have the fundamental role of managing the different practices and organizing them in a systematic care.

The treatment of delirium is still not completely understood, either by the complex pathophysiology of this neurological dysfunction, or by the conflicting results of some studies. However, the protocol developed and validated in this study can assist in the care against delirium in the ICU, since the recommendations were selected from scientific evidence, validated and recommended by professionals with expertise in critical care, which may favor the resolution of delirium and, also, contribute to the improvement of other clinical outcomes.

CONCLUSION

This study validated a multiprofessional care protocol for critically ill patients with delirium, with only four recommendations not being approved. Considering that delirium is a multifactorial dysfunction, its care must be comprehensive, encompassing physiological and pharmacological aspects, pain, agitation, and delirium management, including the use of haloperidol; and psychological aspects, with cognitive reorganization, sleep promotion, and family participation, among others.

A limitation of this study was the composition of the sample, since the participants were not selected from all regions of the country. However, the participants fulfilled the criteria consistent with clinical expertise in the assessed subject.

The importance of this study stands out due to the imminent need to prevent and treat patients who develop delirium in the ICU, since it adds numerous complications and may worsen clinical outcomes. It is also worth mentioning the incorporation of standardized languages (NANDA-I and NIC) in a study focusing on clinical practice and multiprofessional care, thus meeting the complex demands of these patients. However, more researches related to the treatment and prevention of delirium are still needed.

ATTACHMENT

Care of the Multiprofessional Protocol for Patients with Delirium in the ICU Diagnosis, pain management, sedation pause and medications Awaken the patient daily (sedation pause: 6:30 am or 7:30 am). Awaken the patient and perform ventilation test. Assess delirium with CAM-ICU. Perform early mobilization. Assess pain with validated scales. Administer non-opioid analgesics. Ensure analgesia before interventions. Limit the use of medications associated with delirium. Choose sedations that are not a risk factor for delirium. administrate haloperidol. Cognitive Orientation Encourage the team to practice verbal / written orientations whenever possible. Call the patient by name when starting an interaction. Encourage the patient with predetermined questions, established in protocol. Inform the characteristics of the unit, visiting hours, meals and procedures. Explain any noise produced by infusion pumps, alarms and / or ventilator. Provide information to the patient about their health status, prognosis and treatments. Offer means of listening to music and television. From 6 am to 8 pm. Provide glasses and hearing aids for personal use as soon as possible. Sleep Promotion Assess patients for sleep maintenance (Sleep period: 00:00 to 4:00 or 22:00 to 4:00). Prevent the patient from sleeping during the day. Cluster care for uninterrupted sleep. During the night: bath until 10 pm. Avoid administering medication at night - reschedule. Do not interrupt sleep. Record vital signs provided by the central monitor during sleep. Provide ear plugs and / or eye mask for sleep. Individualize the alarm. Check the patient's preference for the sleeping environment. Inform the benefits of the sleep-wake cycle. Assess the risk for PU and the permanence without changing position during sleep. Interrupt the sleep period if the patient's clinical status changes / or if there is instabilities. Environment and Family Participation Orientate using clocks and calendars. Allow family members to bring items: magazines, books, etc. Reduce light at night. Orientate professionals - avoid talking by the bed. Control noise at night. Make family access more flexible. Promote care planning, facilitating family access. Perform rounds in visiting hours to offer orientations about delirium. Encourage family interaction with the patient. Develop educational materials. Remove devices early. Perform “box glove” mechanical restraint. Keep the bed rails high. Provide the patient with a means of calling professionals, eg, bell or light. Identify the bed of the patient who is in delirium, in order to maintain the care protocol.
