Delirium: the lived experience of older people who are delirious post-orthopaedic surgery

Patients' and family members' dyadic experience of post-operative delirium in the intensive care unit: A qualitative study

BACKGROUND

Post-operative delirium is a complication with long-lasting consequences for both patients and their families. This is particularly true for those transferred to the intensive care unit after surgery, where the incidence of post-operative delirium is high, and patient outcomes are often poor. Despite the acknowledged role of family engagement in delirium management, previous research has mainly focused on patients, with limited exploration of the shared experiences between patients and family members.

AIM

This study aims to explore the experiences of patients and family members during episodes of post-operative delirium in the intensive care unit to better understand their unmet needs.

STUDY DESIGN

A qualitative descriptive study was conducted at a tertiary general hospital. Eighteen pairs of patients, their family members and two other family members were interviewed. Data were collected through face-to-face semi-structured interviews within the first week after patients' discharge from the intensive care unit and analysed using thematic analysis.

RESULTS

Four major themes emerged: (1) the dyadic relationship between patients and family members must be understood in the context of their shared emotional and behavioural experiences; (2) family's history may predispose patients to post-operative delirium; (3) family engagement may prevent the development of post-operative delirium; and (4) inadequate communication between health care providers and patients or families may negatively affect post-operative delirium outcomes.

CONCLUSIONS

Post-operative delirium presents significant emotional and physical challenges for both patients and their families. Addressing these challenges requires improved communication between health care providers and families, as well as strategies that emphasize early family support and collaboration in care.

RELEVANCE TO CLINICAL PRACTICE

Patients and their families should be considered a unit during post-operative delirium management, and earlier family engagement is essential. Health care systems should adapt intensive care unit practices to meet the dynamic needs of families, promoting more comprehensive support during critical care.

Shame in patient-health professional encounters: A scoping review

Shame can arise during patient-health professional encounters when discussing traumatising and stigmatising topics and can contribute to negative patient outcomes. This review aims to summarise what is known regarding shame in patient-health professional encounters. We conducted a scoping review using Levac and colleagues' approach and reported the findings using the PRISMA Extension for Scoping Reviews. We searched four databases (CINAHL, PsychINFO, PubMed and SocINDEX) for empirical studies that involved shame in patient-health professional encounters contextualised by trauma or stigma and were published in English. We categorised what is known regarding shame in empirical studies using inductive content analysis. We also collected stakeholders' perspectives on the review findings through an online survey. Our initial search yielded 3658 articles, of which 37 were included. We summarised the literature into four categories: (1) What health professionals say they do in patient-health professional encounters, (2) What health professionals think patients feel in patient-health professional encounters, (3) Patients' descriptions of their own shame during patient-health professional encounters and (4) Health professionals' descriptions of their own shame during patient-health professional encounters. Shame can arise in a variety of circumstances during patient-health professional encounters. More research is needed to identify what specific communication strategies used by health professionals during patient-health professional encounters contribute to or avoid patient shame.

A retrospective, cross-sectional analysis of delirium in burn injury compared to other surgical specialities

BACKGROUND

Delirium is an acute cerebral disorder characterised by a disturbance in cognition, attention, and awareness. Often, it's undiagnosed and associated with increased morbidity and mortality. For burn patients, the reported prevalence ranges from 16% to 39%, with a multifactorial aetiology, increasing when intensive care is required. A direct comparison of delirium between surgical specialities has not been made.

AIM

1. To audit the use of the 4AT for those who become delirious during their stay. 2. Assess the proportion of patients diagnosed with delirium during hospitalisation by surgical specialities. 3. Identification of the factors associated with delirium in surgical patients.

METHODS

Investigators at a single centre conducted a two-phase study. An initial retrospective audit of delirious patients under burns, general, and orthopaedic specialities over 16months, as defined by ICD-10 coding, identified compliance screening with the 4 A's Test. This informed the design of a retrospective, observational cohort study to compare factors associated with delirium and statistical comparison between four specialities to identify delirium-associated factor, where an analysis corrects for age.

RESULTS

37% of patients with an ICD-10 code indicating delirium had a 4AT test completed. Speciality, number of operations, LOS, ICU hours, age, and discharge destination were all statistically significant independent variables. When all other variables were equal, burns had the highest predicted probability of delirium diagnosis.

CONCLUSIONS

Further analysis to identify and diagnose across the specialties is required. From a patient viewpoint, their LOS, ICU hours, and operations are increased for patients coded as delirious compared to non-delirious across the specialities. On a hospital level, the mean difference in cost for a delirious compared to a non-delirious patient is AU$9317. Despite the low incidence of delirium amongst the observed specialities, burns patients were most likely to develop delirium when demographic and clinical profiles were the same, and were more likely to develop delirium at a younger age and if in ICU.

Identifying the relationship between delirium and falls

Delirium, which may present as acute fluctuation in arousal and attention and changes in a person's behaviours, can increase the risk of falls, while a fall can increase the risk of developing delirium. There is, therefore, a fundamental relationship between delirium and falls. This article describes the main types of delirium and the challenges associated with recognition of the condition and discusses the relationship between delirium and falls. The article also describes some of the validated tools used to screen patients for delirium and includes two brief case studies to illustrate this in practice.

Examining Subjective Psychological Experiences of Postoperative Delirium in Older Cardiac Surgery Patients

BACKGROUND

Postoperative delirium (POD) is an acute syndrome including inattention and impaired cognition that affects approximately 42% of older cardiac surgical patients. POD is linked to adverse outcomes including morbidity, mortality, and further cognitive decline. Less is known about the subjective psychological experience of POD and its ongoing impact on well-being.

METHODS

We performed a qualitative analysis of the long-term psychological sequelae of older adults who experience POD after cardiac surgery. We sampled 30 patients aged 60 years and older who experienced at least 2 episodes of POD during a prior hospital admission. We administered semistructured interviews with participants via telephone 3 to 5 years postoperatively. Interviews were transcribed and thematically analyzed. Data were interpreted in accordance with the naturalist paradigm.

RESULTS

Three overarching themes emerged in our qualitative analysis. The first reflected the multifaceted presentation of POD, including distortion of time and reality; feelings of isolation; and a loss of self, identity, and control. The second theme reflected the psychological challenges associated with functional decline after surgery. Common examples of functional decline included cognitive difficulties, excessive fatigue, and a perceived loss of independence. The final theme captured the emotional sequelae of acute illness, which included low mood, reduced motivation, and social comparisons.

CONCLUSIONS

Our findings emphasize the multidimensional experience of POD and long-term effects on psychological wellbeing. Our research highlights the beneficial role multidisciplinary clinicians play in managing POD including strategies that may be embedded into clinical practice and helps anesthesiologists understand why patients who have experienced POD in the past may present with specific concerns should they require subsequent surgery.

Interventions to support recovery following an episode of delirium: A realist synthesis

OBJECTIVES

Persistent delirium is associated with poor outcomes in older adults but little is known about how to support longer-term recovery from delirium. The aim of this review was to identify and synthesise literature to understand mechanisms of recovery from delirium as a basis for designing an intervention that enables more effective recovery.

METHODS

A systematic search of literature relevant to the research question was conducted in two phases. Phase one focused on studies evaluating the efficacy of interventions to support recovery from delirium, and stage two used a wider search strategy to identify other relevant literature including similar patient groups and wider methodologies. Synthesis of the literature followed realist principles.

RESULTS

Phase one identified four relevant studies and stage two identified a further forty-six studies. Three interdependent recovery domains and four recovery facilitators were identified. Recovery domains were 1) support for physical recovery through structured exercise programmes; 2) support for cognitive recovery through reality orientation and cognitive stimulation; 3) support for emotional recovery through talking with skilled helpers. Recovery facilitators were 1) involvement and support of carers; 2) tailoring intervention to individual needs, preferences and abilities; 3) interpersonal connectivity and continuity in relationships and; 4) facilitating positive expressions of self.

CONCLUSIONS

Multicomponent interventions with elements that address all recovery domains and facilitators may have the most promise. Future research should build on this review and explore patients', carers', and professionals' tacit theories about the persistence of delirium or recovery from delirium in order to inform an effective intervention.

Preoperative Delirium Nursing Model Initiatives to Determine the Incidence of Postoperative Delirium Among Elderly Orthopaedic Patients

Delirium is a common neurocognitive disorder prevalent in hospitalized older adults. The development of delirium is associated with adverse health outcomes, including functional decline and mortality. This study aimed to investigate the incidence and risk factors of postoperative delirium in older adults (≥60 years) who underwent orthopaedic surgery. Elderly orthopaedic patients were recruited from a large urban hospital over 12 months. Patients were preoperatively screened for delirium and followed up at least once daily postoperatively until discharge. Of the 124 patients in the sample, 21 (16.9%) had postoperative delirium. There were no significant differences in any of the baseline characteristics between the delirious and nondelirious patients. Patients using antidepressants were more likely to develop postoperative delirium compared with those not using antidepressants (odds ratio: 2.72, p = .05). Postoperative delirium was common in this sample of older adults who underwent orthopaedic surgery. Aiming prevention strategies toward patients using antidepressants may help reduce the incidence of delirium in this population.

Factors associated with the decision to prescribe and administer antipsychotics for older people with delirium: a qualitative descriptive study

OBJECTIVES

To explore factors associated with decision-making of nurses and doctors in prescribing and administering as required antipsychotic medications to older people with delirium.

DESIGN

Qualitative descriptive.

SETTING

Two acute care hospital organisations in Melbourne, Australia.

PARTICIPANTS

Nurses and doctors were invited to participate. Semi-structured focus groups and individual interviews were conducted between May 2019 and March 2020. Interviews were audio-recorded and transcribed verbatim. Data were analysed using thematic analysis.

RESULTS

Participants were 42 health professionals; n=25 nurses and n=17 doctors. Themes relating to decisions to use antipsychotic medication were: safety; a last resort; nursing workload; a dilemma to medicate; and anticipating worsening behaviours. Nurses and doctors described experiencing pressures when trying to manage hyperactive behaviours. Safety was a major concern leading to the decision to use antipsychotics. Antipsychotics were often used as chemical restraints to 'sedate' a patient with delirium because nurses 'can't do their job'. Results also indicated that nurses had influence over doctors' decisions despite nurses being unaware of this influence. Health professionals' descriptions are illustrated in a decision-making flowchart that identifies how nurses and doctors navigated decisions regarding prescription and administration of antipsychotic medications.

CONCLUSIONS

The decision to prescribe and administer antipsychotic medications for people with delirium is complex as nurses and doctors must navigate multiple factors before making the decision. Collaborative support and multidisciplinary teamwork are required by both nurses and doctors to optimally care for people with delirium. Decision-making support for nurses and doctors may also help to navigate the multiple factors that influence the decision to prescribe antipsychotics.

Patients' experiences of delirium: A systematic review and meta-summary of qualitative research

AIMS

The purpose of this systematic review and meta-summary was the aggregation of the empirical qualitative literature on patients' experiences of delirium in order to support the development and implementation of patient-oriented delirium management and to guide future research.

DESIGN

We conducted a systematic literature review of qualitative research published between January 1980 and June 2019.

DATA SOURCES

In June 2019, we searched in Medline, CINAHL, SSCI and PsycInfo to identify relevant reports. In addition, we conducted searches in three dissertation databases (BASE, DART and ProQuest) and Google Scholar.

REVIEW METHODS

We used methods developed by Sandelowski and Barroso to construct a meta-summary of the findings by extracting them from the reports, abstracting them into meta- findings and calculating their manifest interstudy frequency effect sizes.

RESULTS

Out of the 742 identified records, 24 reports based on delirium experience accounts of 483 patients met our criteria and were included. One thousand ninety-seven findings were extracted from these reports and abstracted into 92 meta-findings. These were grouped to the five emerging themes 'perception', 'emotions', 'interaction with others', 'dealing with delirium' and 'influence on further life'.

CONCLUSION

Delirium is commonly perceived as an overall distressing condition, which can accompany and influence patients even after hospital discharge.

IMPACT

This systematic review and meta-summary is the most comprehensive aggregation of qualitative research of the patient delirium experience to date. It allows us to better understand, extract meaning from, and weigh the qualitative findings in their context by calculating their manifest frequency effect sizes. This can be used to support the development and implementation of delirium management concepts.

Predicting hospital outcomes with the reported edmonton frail scale-Thai version in orthopaedic older patients

AIMS AND OBJECTIVES

To test the ability of the Reported Edmonton Frail Scale-Thai version to predict hospital outcomes compared with standard preoperative assessment measures (American Society of Anesthesiologists physical status classification and the Elixhauser Comorbidity Measure) in older Thai orthopaedic patients.

BACKGROUND

Frailty is a common geriatric condition. No previous studies have assessed frailty among orthopaedic patients in Thailand. Effective frailty screening could enhance quality of care.

DESIGN

Prospective cohort study in a university hospital.

METHODS

Two hundred hospitalised patients, aged 60 years or older and scheduled for orthopaedic surgery, participated in the study. Frailty was evaluated using the Reported Edmonton Frail Scale-Thai version. Multiple Firth logistic regression was used to model the effect of frailty on postoperative complications, postoperative delirium and discharge disposition. Length of stay was examined using Poisson regression. Comparing predictability of the instruments, the area under the receiver operating characteristic curve and mean squared errors were evaluated. The STROBE guideline was used.

RESULTS

Participants' mean age was 72 years; mostly were female, frail and underwent knee, spine and/or hip surgery. Poor health outcomes including postoperative complications, postoperative delirium, and not being discharged to the home were commonly identified. The length of stay varied from three days to more than ten weeks. Frailty was significantly associated with postoperative complications, postoperative delirium and prolonged length of stay. The Reported Edmonton Frail Scale-Thai version revealed good performance for predicting postoperative complications and postoperative delirium and was improved by combining with standard assessments.

CONCLUSION

The Reported Edmonton Frail Scale-Thai version, alone or combined with standard assessment, was useful for predicting adverse outcomes in older adults undergoing orthopaedic surgery.

RELEVANCE TO CLINICAL PRACTICE

These findings indicate that nurse professionals should apply culturally sensitive frailty screening to proactively identify patients' risk of frailty, improve care quality and prevent adverse outcomes.

Development and Evaluation of Clinical Practice Guideline for Delirium in Long-Term Care

Delirium is highly prevalent and leads to several bad outcomes for older long-term care (LTC) residents. For a more successful translation of delirium knowledge, Clinical Practice Guidelines (CPGs) tailored to LTC should be developed and applied based on the understanding of the barriers to implementation. This study was conducted to develop a CPG for delirium in LTC and to determine the barriers perceived by healthcare professionals related to the implementation of the CPG. We followed a structured, evidence- and theory-based procedure during the development process. After a systematic search, quality appraisal, and selection for eligible up-to-date CPGs for delirium, the recommendations applicable to the LTC were drafted, evaluated, and confirmed by an external group of experts. To evaluate the barriers to guideline uptake from the users' perspectives, semi-structured interviews were conducted which resulted in four major themes: (1) a lack of resources, (2) a tendency to follow mindlines rather than guidelines, (3) passive attitudes, and (4) misunderstanding delirium care in LTC. To minimize adverse prognoses through prompt delirium care, the implementation of a CPG with an approach that comprehensively considers various barriers at the system, practice, healthcare professional, and patients/family levels is necessary.

Stigma Associated with Opioid Use Disorders in Adolescents Limits Naloxone Prescribing

THEORETICAL PRINCIPLES

Parse's theory of humanbecoming describes shame as a sense that one is failing to conform to both personal and societal expectations of high value. Shame and stigma, negative perceptions others hold of an individual based on failure to conform to societal expectations, that surround opioid use disorders are linked to patients not seeking medical treatment due to the social isolation and humiliation brought on by the disease.

PHENOMENON ADDRESSED

This article reviews the resistance of some health care providers to discuss the realities of substance abuse with adolescent patients and their families, and identifies how the stigma that some health care providers place on opioid use disorders makes them less likely to discuss and prescribe naloxone, the reversal agent for opioids. When families are prepared to prevent overdose deaths by administering naloxone, lives can be saved, and time can be preserved for developing long-term treatment options.

RESEARCH LINKAGES

Research should develop curricula that teach how to identify unconscious bias that may exist on the part of the healthcare provider, and to understand the negative effects of stigmatizing opioid use. Bedside nurses and practitioners should be equipped to educate patients and their families about naloxone and its availability, and to explain that it is a safe and effective way to prevent opioid related deaths. When presented in a nonjudgmental way, information about naloxone is a critical component in addressing the opioid epidemic, preventing deaths and providing time for further treatment options.

Perspectives on the Delirium Experience and Its Burden: Common Themes Among Older Patients, Their Family Caregivers, and Nurses

BACKGROUND AND OBJECTIVES

While there are qualitative studies examining the delirium-related experiences of patients, family caregivers, and nurses separately, little is known about common aspects of delirium burden among all three groups. We describe common delirium burdens from the perspectives of patients, family caregivers, and nurses.

RESEARCH DESIGN AND METHODS

We conducted semistructured qualitative interviews about delirium burden with 18 patients who had recently experienced a delirium episode, with 16 family caregivers, and with 15 nurses who routinely cared for patients with delirium. We recruited participants from a large, urban teaching hospital in Boston, Massachusetts. Interviews were recorded and transcribed. We used interpretive description as the approach to data analysis.

RESULTS

We identified three common burden themes of the delirium experience: Symptom Burden (Disorientation, Hallucinations/Delusions, Impaired Communication, Memory Problems, Personality Changes, Sleep Disturbances); Emotional Burden (Anger/Frustration, Emotional Distress, Fear, Guilt, Helplessness); and Situational Burden (Loss of Control, Lack of Attention, Lack of Knowledge, Lack of Resources, Safety Concerns, Unpredictability, Unpreparedness). These burdens arise from different sources among patients, family caregivers, and nurses, with markedly differing perspectives on the burden experience.

DISCUSSION AND IMPLICATIONS

Our findings advance the understanding of common burdens of the delirium experience for all groups and offer structure for instrument development and distinct interventions to address the burden of delirium as an individual or group experience. Our work reinforces that no one group experiences delirium in isolation. Delirium is a shared experience that will respond best to systemwide approaches to reduce associated burden.

Cognitive outcomes following coronary artery bypass grafting: A systematic review and meta-analysis of 91,829 patients

Background

Cognitive impairments, including delirium, are common after coronary artery bypass grafting (CABG) surgery, as described in over three decades of research. Our aim was to pool estimates across the literature for the first-time, relative to time (from pre- to post-CABG) and diagnosis (cognitive impairment, delirium and dementia).

Methods

A systematic search of four databases was undertaken. 215 studies incorporating data from 91,829 patients were used to estimate the prevalence of cognitive impairments pre- and post-CABG, including delirium and dementia post-CABG, using random effects meta-analyses.

Results

Pre-surgical cognitive impairment was seen in 19% of patients. Post-operatively, cognitive impairment was seen in around 43% of patients acutely; this resolved to 19% at 4–6 months and then increased to 25% of patients between 6-months to 1-year post-operatively. In the long term, between 1 and 5-years post-operatively, cognitive impairment increased and was seen in nearly 40% of patients. Post-operative delirium was apparent in 18% of CABG patients which increased to 24% when a diagnostic instrument was utilized alongside clinical criteria. Dementia was present in 7% of patients 5–7 years post-surgery.

Conclusion

The results of this meta-analysis demonstrate that cognitive impairment and delirium are major issues in CABG patients which require specific attention. It is imperative that appropriate methods for investigating cognitive impairment, and screening for delirium using a diagnostic instrument, occur in both pre-and post-CABG settings.

•

This meta-analysis pooled results of 91,829 patients, including 215 studies.

•

Cognitive impairment and delirium are seen in up to 40% of CABG patients.

•

Appropriate methods investigating cognitive impairment are crucial post-CABG.

•

Appropriate methods of screening for delirium are crucial post-CABG.

Don't go there - It's not a nice place: Older adults' experiences of delirium

Delirium is a common neuropsychiatric disorder that causes fluctuations in consciousness and attention, impairments in cognitive functioning and information processing, and changes in how individuals perceive what is going on around them. Delirium is associated with increased mortality, ongoing impairment in cognitive functioning, and a high possibility of discharge to residential care. The experience of delirium may be distressing for the patient and their family. Despite the frequency of delirium in hospitalized elderly patients, there is a dearth of literature that examines their experience of this phenomenon, and how it affects individuals as they continue their lives. This study uses descriptive qualitative methodology to explore the question: 'What is the experience of delirium for older adults during hospitalisation?' Data were collected from older adults who had received hospital care in a tertiary general hospital setting. Seven participants were recruited between January and June 2017. Semi-structured individual interviews were used to gather data which was analysed using content analysis. Four themes were identified. These were sense of confusion, disrupted sense of autonomy, perceptual disturbances, and emotional response. Participants exercised agency in the way they responded to these experiences. The study highlighted the need for delirium prevention, and education to improve nurses' recognition, understanding, and management of delirium. In particular, there is a need for nurses to attend to the psychological and emotional experience of delirium.

‘I hope you get normal again’: an explorative study on how delirious octogenarian patients experience their interactions with healthcare professionals and relatives after aortic valve therapy

Background:

Delirium affects nearly half of octogenarian patients after aortic valve replacement, resulting in impaired cognition, reduced awareness and hallucinations. Although healthcare professionals and relatives are often present during episodes, the nature of interactions with them is scarcely studied, and little is known about their long-term experiences.

Purpose:

The purpose of this study was to explore and describe how octogenarian patients with post-aortic valve replacement delirium experience interactions with healthcare professionals and relatives within the first year and four years later.

Method:

An explorative design with qualitative content analysis was used. Delirium was assessed for five consecutive days after aortic valve replacement using the Confusion Assessment Method. Delirious patients ( n=10) were interviewed 6–12 months post-discharge and four years later ( n=5). We used an inductive approach to identify themes in transcribed interviews.

Findings:

An overarching theme emerged: ‘ Healthcare professionals’ and relatives’ responses made a considerable impact on the delirium experience postoperatively and in a long-term’. Three sub-themes described the patients’ experiences: ‘ the need for close supportive care’, ‘ disrespectful behaviour created a barrier’ and ‘ insensitive comments made lasting impressions’. Having healthcare professionals and relatives nearby made the patients feel secure, while lack of attention elevated patients’ emotional distress. Four years later, patients clearly recalled negative comments and unsupportive actions in their delirious state.

Conclusions:

Healthcare professionals and relatives have an essential role in the aortic valve replacement recovery process. Inconsiderate behaviour directed at older patients in delirium elevates distress and has long-term implications. Supportive care focused on maintaining the patients’ dignity and integrity is vital.

Educational Intervention to Improve Delirium Recognition by Nurses

BACKGROUND

Delirium poses increased morbidity and mortality risks for hospitalized patients. Underrecognition by health care providers contributes to poor outcomes for patients. Little has been published about methods used to teach health care providers how to screen for delirium using the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU).

OBJECTIVE

To evaluate the effectiveness of a multimodal educational intervention for nurses in the medical intensive care unit to improve their knowledge and skills regarding delirium and delirium recognition.

METHODS

An educational intervention was done in the medical intensive care unit of an academic medical center. Effectiveness was evaluated via a quasi-experimental design and using preintervention and postintervention assessments. Procedural correctness of performing the CAM-ICU delirium screening also was measured.

RESULTS

Nurses participated in 1 small-group session (n = 34). Fifteen sessions were conducted from June to September 2016, and assessments were completed before and after the intervention. The sample consisted of predominantly nurses with a bachelor's degree (56%) who had 1 to 5 years' experience (59%). Mean scores overall and on the knowledge subscale differed significantly (P < .001) from before to after the intervention. No correlation was found between demographic groups and score differences. Seventy-nine percent of participants used the tool correctly after the intervention.

CONCLUSIONS

The educational intervention provided for these nurses further validated published reports of the benefits of an educational program about delirium. The content of the educational intervention should be targeted for the setting, the risk factors for the patient population in question, and the specific delirium screening tool used.

Systematic review of prediction models for delirium in the older adult inpatient

OBJECTIVE

To identify existing prognostic delirium prediction models and evaluate their validity and statistical methodology in the older adult (≥60 years) acute hospital population.

DESIGN

Systematic review.

DATA SOURCES AND METHODS

PubMed, CINAHL, PsychINFO, SocINFO, Cochrane, Web of Science and Embase were searched from 1 January 1990 to 31 December 2016. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses and CHARMS Statement guided protocol development.

INCLUSION CRITERIA

age >60 years, inpatient, developed/validated a prognostic delirium prediction model.

EXCLUSION CRITERIA

alcohol-related delirium, sample size ≤50. The primary performance measures were calibration and discrimination statistics. Two authors independently conducted search and extracted data. The synthesis of data was done by the first author. Disagreement was resolved by the mentoring author.

RESULTS

The initial search resulted in 7,502 studies. Following full-text review of 192 studies, 33 were excluded based on age criteria (<60 years) and 27 met the defined criteria. Twenty-three delirium prediction models were identified, 14 were externally validated and 3 were internally validated. The following populations were represented: 11 medical, 3 medical/surgical and 13 surgical. The assessment of delirium was often non-systematic, resulting in varied incidence. Fourteen models were externally validated with an area under the receiver operating curve range from 0.52 to 0.94. Limitations in design, data collection methods and model metric reporting statistics were identified.

CONCLUSIONS

Delirium prediction models for older adults show variable and typically inadequate predictive capabilities. Our review highlights the need for development of robust models to predict delirium in older inpatients. We provide recommendations for the development of such models.

Integrative Literature Review on Shame

Shame is a universal living experience that is just beginning to be explored within the discipline of nursing. Development of a broad understanding of shame is needed to aid nurse researchers in clarifying this phenomenon from a nursing perspective. Pursuant to this goal, the author in this article reviews the extant literature on shame from the disciplines of nursing, psychology, sociology, philosophy, and theology. Three themes that emerged from the scholarly literature were (a) shame propels miring in paralysis, (b) shame captures the illusionary seen-unseen, and
