Psychological issues in the care of critically-ill respirator patients: differential perceptions of patients, relatives, and staff

Determinants of Communication Failure in Intubated Critically Ill Patients: A Qualitative Phenomenological Study from the Perspective of Critical Care Nurses

AIM

To explore what factors determine communication with awake intubated critically ill patients from the point of view of critical care nursing professionals.

BACKGROUND

Impaired communication frequently affects mechanically ventilated patients with artificial airways in the intensive care unit. Consequences of communication breaches comprise emotional and ethical aspects as well as clinical safety, affecting both patients and their conversation partners. Identification of determining factors in communication with awake intubated patients is needed to design effective action strategies.

DESIGN

A qualitative phenomenological approach was used.

METHODS

Semi-structured interviews were used as the data collection method. A total of 11 participants from three intensive care units of three Majorcan public hospitals, selected by purposive sampling, were interviewed.

FINDINGS

Three major themes regarding the communication determinants of the awake intubated critically ill patients were identified from the interviewees' statements: factors related to the patient (physical and cognitive functionality to communicate, their relational and communicative style and their personal circumstances), to the context (family presence, ICU characteristics, workload, availability/adequacy of communication aids, features of the messages and communication situations) and, finally, those related to the professionals themselves (professional experience and person-centredness).

CONCLUSIONS

The present study reveals determinants that influence communication with the awake intubated patient, as there are attitudes and professional beliefs.

RELEVANCE TO CLINICAL PRACTICE

The discovery of relations between different kinds of determinants (of patient, context or professionals) provides a multi-factor perspective on the communicative problem which should be considered in the design of new approaches to improve communicative effectiveness. This study is reported according to the COREQ checklist.

Prolonged Ventilator Dependence

The purpose of this qualitative inquiry was to examine the meaning of prolonged mechanical ventilation from the perspective of the patient with a diagnosis of chronic obstructive pulmonary disease (COPD). Interviews were conducted with four individuals with a diagnosis of COPD who had experienced long-term ventilator dependence. Participants were asked to reflect on their experiences while they were ventilator dependent, and their narratives were utilized as text for hermeneutical analysis. The study's findings describe three distinct phases experienced by the participants, beginning with intubation and lasting until well after discharge from the hospital. The support of nurses was an important aspect of maintaining hope for the participants. The study revealed that prolonged mechanical ventilation had a profound impact on COPD patients and their sense of self. Postdischarge psychological support and follow-up with survivors of this experience is warranted.

Providing Care in the End of Life

As modern technology advances, people live longer and are more likely to face death later in life from chronic or degenerative diseases. The location of death has also changed, resulting in more people dying in impersonal settings. The final months in the life of George, a terminally ill 89-year-old Caucasian male are discussed from four perspectives: existential approach, the stage model of death and dying, the reinforcement model, and an integrated model. Therapeutic interventions, aimed toward assisting George in dealing with his medical condition and existential issues, consisted of the following three major components: family therapy, religiosity, and preparation for death. Ethical and therapeutic considerations related to issues of death and dying are addressed.

Nonvocal Ventilated Patients Perceptions of Being Understood

This metasynthesis presents an enlarged interpretation and understanding of nonvocal mechanically ventilated patients’experiences with communication. Peplau’s interpersonal relations theory provided the theoretical framework for the metasynthesis. The final sample included 12 qualitative studies, for a total of 111 participants. The data, methods, and theoretical frameworks were critically interpreted. Commonthreads detected across study participants’individual experiences were synthesized to form a greater understanding of nonvocal ventilated patients’ perceptions of being understood. Five overarching themes were divided into two groups. The first group of themes was categorized as the characteristics of nonvocal ventilated patients’communication experiences. Nonvocal individuals were often not understood, which resulted in loss of control and negative emotional responses. The second group of themes was categorized as the kind of nursing care desired by nonvocal patients in order to be understood. Nonvocal patients wanted nursing care that was delivered in an individualized, caring manner. This facilitated positive interpersonal relations between the patient and the nurse. Findings are discussed in relation to the current state of knowledge on this topic.

Adaptation of a communication interaction behavior instrument for use in mechanically ventilated, nonvocal older adults

BACKGROUND

Valid and reliable instruments are needed to measure communication interaction behaviors between nurses and mechanically ventilated intensive care unit patients who are without oral speech.

OBJECTIVES

The aim of this study was to refine and evaluate preliminary validity and reliability of a Communication Interaction Behavior Instrument (CIBI) adapted for use with mechanically ventilated, nonvocal patients in the intensive care unit.

METHODS

Raters observed nurse-patient communication interactions using a checklist of nurse and patient behaviors, categorized as positive and negative behaviors. Three-minute video-recorded observations of five mechanically ventilated adults (<60 years old) in the intensive care unit and their nurses were used to establish preliminary interrater reliability and confirm appropriateness of definitions (four observations per dyad, n = 20). On the basis of expert input and reliability results, the behaviors and item definitions on the CIBI were revised. The revised tool was then tested in a larger sample of 38 mechanically ventilated intensive care patients (> 60 years old) and their nurses (four observations per dyad, n = 152) to determine interrater reliability.

RESULTS

For preliminary testing, percent agreement for individual items ranged from 60% to 100% for nurse behaviors and 20% to 100% for patient behaviors across the five pilot cases. On the basis of these results, 11 definitions were modified and four items were dropped. Using the revised 29-item instrument, percent agreement improved for nurse behaviors (73%-100%) and patient behaviors (68%-100%). Kappa coefficients ranged from 0.13 to 1.00, with lower coefficients for patient behaviors.

CONCLUSION

Preliminary results suggest that the revised CIBI has good face validity and shows good interrater reliability for many of the behaviors, but further refinement is needed. The use of dual raters with adjudication of discrepancies is the recommended method of administration for the revised CIBI.

Nurse and patient characteristics associated with duration of nurse talk during patient encounters in ICU

BACKGROUND

Communication interactions between nurses and mechanically ventilated patients in the intensive care unit (ICU) are typically brief. Factors associated with length of nurses' communication have not been explored.

OBJECTIVE

To examine the association between nurse and patient characteristics and duration of nurse talk.

METHODS

In this secondary analysis, we calculated duration of nurse talk in the first 3-min of video-recorded communication observation sessions for each nurse-patient dyad (n = 89) in the SPEACS study (4 observation sessions/dyad, n = 356). In addition, we explored the association between nurses' characteristics (age, gender, credentials, nursing experience, and critical care experience) and patients' characteristics (age, gender, race, education, delirium, agitation-sedation, severity of illness, level of consciousness, prior intubation history, days intubated prior to study enrollment, and type of intubation) on duration of nurse talk during the 3-min interaction observation.

RESULTS

Duration of nurse talk ranged from 0-123 s and varied significantly over the 4 observation sessions (p = .007). Averaging the duration of nurse talk over the observation sessions, differences in talk time between the units varied significantly by study group (p < .001). Talk duration was negatively associated with a Glasgow Coma Scale ≤14 (p = .008). Length of intubation prior to study enrollment had a curvilinear relationship with talking duration (linear p = .002, quadratic p = .013); the point of inflection was at 23 days. Nurse characteristics were not significantly related to duration of nurse talk.

CONCLUSION

Length of time the patient is intubated, and the patient's level of consciousness may influence duration of nurse communication in ICU.

Challenge of assessing symptoms in seriously ill intensive care unit patients: can proxy reporters help?

OBJECTIVE

Determine levels of agreement among intensive care unit patients and their family members, nurses, and physicians (proxies) regarding patients' symptoms and compare levels of mean intensity (i.e., the magnitude of a symptom sensation) and distress (i.e., the degree of emotionality that a symptom engenders) of symptoms among patients and proxy reporters.

DESIGN

Prospective study of proxy reporters of symptoms in seriously ill patients.

SETTINGS

Two intensive care units in a tertiary medical center in the Western United States.

PATIENTS

Two hundred and forty-five intensive care unit patients, 243 family members, 103 nurses, and 92 physicians.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

On the basis of the magnitude of intraclass correlation coefficients, where coefficients from .35 to .78 are considered to be appropriately robust, correlation coefficients between patients' and family members' ratings met this criterion (≥.35) for intensity in six of ten symptoms. No intensity ratings between patients and nurses had intraclass correlation coefficients >.32. Three symptoms had intensity correlation coefficients of ≥.36 between patients' and physicians' ratings. Correlation coefficients between patients and family members were >.40 for five symptom-distress ratings. No symptoms had distress correlation coefficients of ≥.28 between patients' and nurses' ratings. Two symptoms had symptom-distress correlation coefficients between patients' and physicians' ratings at >.39. Family members, nurses, and physicians reported higher symptom-intensity scores than patients did for 80%, 60%, and 60% of the symptoms, respectively. Family members, nurses, and physicians reported higher symptom-distress scores than patients did for 90%, 70%, and 80% of the symptoms, respectively.

CONCLUSIONS

Patient-family intraclass correlation coefficients were sufficiently close for us to consider using family members to help assess intensive care unit patients' symptoms. Relatively low intraclass correlation coefficients between intensive care unit clinicians' and patients' symptom ratings indicate that some proxy raters overestimate whereas others underestimate patients' symptoms. Proxy overestimation of patients' symptom scores warrants further study because this may influence decisions about treating patients' symptoms.

Use of augmentative and alternative communication strategies by family members in the intensive care unit

BACKGROUND

Little is known about communication between patients and their family members during critical illness and mechanical ventilation in the intensive care unit, including use of augmentative and alternative communication tools and strategies.

OBJECTIVES

To identify (1) which augmentative and alternative communication tools families use with nonspeaking intensive care patients and how they are used, and (2) what families and nurses say about communication of family members with nonspeaking intensive care patients.

METHODS

A qualitative secondary analysis was conducted of existing data from a clinical trial testing interventions to improve communication between nurses and intensive care patients. Narrative study data (field notes, intervention logs, nurses' interviews) from 127 critically ill adults were reviewed for evidence of family involvement with augmentative and alternative communication tools. Qualitative content analysis was applied for thematic description of family members' and nurses' accounts of patient-family communication.

RESULTS

Family involvement with augmentative and alternative communication tools was evident in 44% of the 93 patients who completed the parent study protocol. Spouses or significant others communicated with patients most often. Main themes describing patient-family communication included (1) families being unprepared and unaware, (2) families' perceptions of communication effectiveness, (3) nurses deferring to or guiding patient-family communication, (4) patients' communication characteristics, and (5) families' experience with and interest in augmentative and alternative communication tools.

CONCLUSIONS

Assessment by skilled bedside clinicians can reveal patients' communication potential and facilitate useful augmentative and alternative communication tools and strategies for patients and their families.

Satisfaction with communication in ICU patients and relatives: comparisons with medical staffs' expectations and the relationship with psychological distress

OBJECTIVE

To study intensive care unit (ICU) patients' and relatives' satisfaction in regard to communication with medical staff (nurses and physicians), perceived support, environmental strain and their psychological distress. Further, to compare this with expectations of the medical staff.

METHODS

Cross-sectional study, 4-6 weeks post-ICU discharge. Respondents to the questionnaire were: 255 (63%) patients, 354 (82%) relatives and 145 (74%) medical staff. Degree of satisfaction and distress were measured on a five-point Likert-scale (0=low to 4=high).

RESULTS

The mean score for patient satisfaction with communication was 3.0 (95%CI 2.9-3.1) and for relatives 3.4 (3.3-3.5). This was significantly higher than expected by the staff for patients 2.5 (2.4-2.6) and relatives 2.8 (2.7-2.9), both p<0.001. Relatives' degree of psychological distress, 2.5 (2.4-2.6) was significantly higher than for patients', 1.6 (1.5-1.7), but was significantly lower than expected by the staff, 2.9 (2.8-3.0) and 2.7 (2.6-2.8) respectively, both p<0.001.

CONCLUSION

Patients and relatives were more satisfied with the communication than expected by the staff. The staff overestimated the patients' and relatives' psychological distress. Relatives report more psychological distress symptoms post-ICU discharge compared to the patients.

PRACTICE IMPLICATIONS

Medical staff is aware of psychological distress in ICU patients and relatives and effort to reduce this during ICU stay and afterwards should be implemented.

Depressive disorders during weaning from prolonged mechanical ventilation

PURPOSE

Patients who require mechanical ventilation are at risk of emotional stress because of total dependence on a machine for breathing. The stress may negatively impact ventilator weaning and survival. The purpose of this study was to determine whether depressive disorders in patients being weaned from prolonged mechanical ventilation are linked to weaning failure and decreased survival.

METHODS

A prospective study of 478 consecutive patients transferred to a long-term acute care hospital for weaning from prolonged ventilation was undertaken. A clinical psychologist conducted a psychiatric interview to assess for the presence of depressive disorders.

RESULTS

Of the 478 patients, 142 had persistent coma or delirium and were unable to be evaluated for depressive disorders. Of the remaining 336 patients, 142 (42%) were diagnosed with depressive disorders. In multivariate analysis, co-morbidity score [odds ratio (OR), 1.23; P = 0.007], functional dependence before the acute illness (OR, 1.70, P = 0.03) and history of psychiatric disorders (OR, 3.04, P = 0.0001) were independent predictors of depressive disorders. The rate of weaning failure was higher in patients with depressive disorders than in those without such disorders (61 vs. 33%, P = 0.0001), as was mortality (24 vs. 10%, P = 0.0008). The presence of depressive disorders was independently associated with mortality (OR, 4.3; P = 0.0002); age (OR, 1.06; P = 0.001) and co-morbidity score (OR, 1.24; P = 0.02) also predicted mortality.

CONCLUSION

Depressive disorders were diagnosed in 42% of patients who were being weaned from prolonged ventilation. Patients with depressive disorders were more likely to experience weaning failure and death.

A systematic review of the experiences of adult ventilator-dependent patients

OBJECTIVES

The objective of this meta-synthesis study was to describe the nature of the experience of adult ventilator-dependent patients.

INCLUSION CRITERIA

This review considered studies utilized qualitative methods to examine the experience of adult with ventilator. The phenomena of interest were experiences of patients who were treated with ventilator for both short term and long term in ICU settings or home settings. The research was limited to studies published in Chinese or in English language.

SEARCH STRATEGY

The searching strategy sought to find both published and unpublished studies. The CINAHL, PubMed, MEDLINE, Cochrane Library, Chinese Periodicals Index and JIB website were used to search the articles. The preliminary keywords were drawn from the natural language terms of the topic, in the title, abstract and subject descriptors.

METHODOLOGICAL QUALITY

Each paper was assessed independently by two reviewers for methodological quality. The Joanna Briggs Institute's Qualitative Assessment and Review Instrument were used to appraisal the methodological quality of the articles. Any disagreements that arose between the reviewers were resolved through discussion with a third reviewer.

DATA SYNTHESIS

Qualitative research findings were pooled and the data analysis process involved synthesizing findings to generate a set of statements that represent the nature of the experiences of ventilator-dependent adult patients. The categories and themes/meta-syntheses were emerged from the analysis process.

RESULTS

A total of 997 papers were identified from various database and hand searches. Nineteen papers were critically appraised and 15 met inclusion criteria. Four papers were excluded because they did not meet the inclusion criteria. Five themes/meta-syntheses emerged from the analysis: 1). The feelings of fear due to being dependent on ventilator and the loss of control of life, 2). Disconnection with reality, 3). Impaired embodiment (body image and body boundary), 4). Construction of coping patterns, 5). Trust and caring relationship.

CONCLUSION

The five themes/meta-syntheses derived from the review represent the patients' experiences in regarding the threatening of the integrity of self, self-other and self-environment relationships, the coping patterns and resilient resources to maintain their self-identify and the meaning of life. These findings also illustrate the resiliency factors for those patients to cope with this stressful situation.The implications to practice include enhancing the trust relationship with health professionals, as well as the nursing actions prior to suction, during the suction procedure and post suction in related to release their psychological distress and empower their resilience factors was suggested.Furthermore, the further research could focus on the development and implementation of support programs for the patients, families, and health professionals, as well as the research regarding the reduction of psychological distress and empower the coping patterns.

Patients' memory and psychological distress after ICU stay compared with expectations of the relatives

PURPOSE

To compare patients' psychological distress and memories from intensive care unit (ICU) treatment 4-6 weeks after ICU discharge with expectations of their relatives. Further, to explore the relationship between personality traits and ICU memories with psychological distress.

METHODS

A cross-sectional study of 255 patients and 298 relatives. The questionnaire included: hospital anxiety and depression scale (HADS), impact of event scale (IES), life orientation test, ICU memory tool and memory of ICU; technical procedures, pain, lack of control and inability to express needs. Relatives were assessed for their expectations of the patients' memories and psychological distress.

RESULTS

Twenty-five percent of the patients reported severe posttraumatic stress symptoms, IES-total >or= 35. The levels of anxiety and depression were significantly higher than in the general population, mean anxiety was 5.6 versus 4.2 (p < 0.001), and mean depression was 4.8 versus 3.5 (p < 0.001). Relatives expected more psychological distress and the relatives thought the patient was less able to express needs than the patients reported (p < 0.001). Higher age, unemployment, respirator treatment, pessimism, memory of pain, lack of control and inability to express needs were independent predictors of posttraumatic stress symptoms (p < 0.01).

CONCLUSIONS

Psychological distress symptoms were frequent among ICU survivors. Relatives expected the patients to be more distressed after ICU treatment than the patients reported. The strongest predictors of posttraumatic stress symptoms from the ICU were memoris about pain, lack of control and inability to express needs. Pessimism may be a reason for psychological distress and should be addressed during follow up, as pessimistic patients may need more motivation and support.

Communication boards in critical care: patients' views

BACKGROUND

Some patients receiving mechanical ventilation experience an intensified need to communicate while their ability to do so is compromised as the endotracheal tube prevents speech. Although the use of a communication board to enhance communication with such patients has been suggested, few descriptive or empirical studies have addressed the content and format of these devices or of patients' perspectives on decreasing frustration with communication.

OBJECTIVES

The objectives of this study were: (1) to identify the perceived level of frustration of patients receiving mechanical ventilation while they attempt to communicate; (2) to determine patients' perceived level of frustration if a communication board had been used; and (3) to describe patients' perceptions of the appropriate content and format of a communication board.

METHODS

Twenty-nine critically ill patients who were extubated within the past 72 hours were included in this descriptive study. Subjects participated in a 20- to 60-minute audiotaped interview consisting of questions about their perceived level of frustration when communicating with and without a communication board and their thoughts about the appropriate content and format of a board. Transcripts were analyzed by questions for meaning and overall themes.

RESULTS

Sixty-two percent (n = 18) of patients reported a high level of frustration in communicating their needs while receiving mechanical ventilation. Patients judged that their perceived level of frustration in communicating their needs would have been significantly lower (P < .001) if a communication board had been offered (29.8%) than if not (75.8%). Most patients (69%; n = 20) perceived that a communication board would have been helpful, and they also identified specific characteristics and content for a communication board. A communication board may be an effective intervention for decreasing patients' frustration and facilitating communication.

CONCLUSIONS

Most patients receiving mechanical ventilation experienced a moderate to a high level of frustration when communicating their needs. In this study, a communication board, if used patiently during mechanical ventilation, has been shown to alleviate frustration with communication. Patients have specific ideas about what terms and ideograms are useful for a communication board. Further research is needed to test the effects of a communication board and other methods of facilitating communication on outcomes such as satisfaction and anxiety of patients, adequate and appropriate management of pain, and length of mechanical ventilation time and hospital stay.

A qualitative study of the experiences of patients following transfer from intensive care

In nursing literature much attention has been paid to patients' experiences while in intensive care. Extensive literature exists examining the longer-term effects of critical care [Jones C, Humphris GM, Griffiths RD. Psychological morbidity following critical illness - the rationale for care after intensive care. Clinical Intensive Care 1998;9:199-205; Griffiths RD, Jones C. ABC of intensive care. Recovery from intensive care. Br Med J 1999;319:417-429]. There is an apparent scarcity of data examining patients' experiences immediately following discharge to wards. A Husserlian phenomenological approach was utilised to gain some understanding of the experience of patients following transfer from intensive care. Ten patients selected purposively comprised the sample. Interviews were performed on the wards 3-5 days following transfer from intensive care. Data was analysed utilising () [Colaizzi PF. Psychological Research as the phenomenologist views it. In: Valle R, King M, editors. Alternatives for psychology. New York: Oxford University Press; 1978. p. 48-71] procedural approach to phenomenological interpretation and analysis. Three major themes emerged: physical response, psychological response and provision of care. These provide a possible framework for patient assessment. Implications for future practice and study are discussed.

Patients' reports of health care practitioner interventions that are related to communication during mechanical ventilation

BACKGROUND

The literature supports nursing interventions to maximize communication in mechanically ventilated patients, yet limited research exists on patients' perceptions of the helpfulness of health care practitioner interventions to enhance communication. In addition, the level of frustration experienced by these patients has not been reported. Thus, further research is necessary to examine patients' perspectives of the helpfulness of health care practitioner interventions that enhance communication of the mechanically ventilated patient.

OBJECTIVES

This study describes the level of frustration experienced by mechanically ventilated patients and ascertains the helpfulness of methods used by health care practitioners to meet the communication needs of the mechanically ventilated patient.

METHODS

A total of 29 critically ill patients, extubated within the last 72 hours, were included in this descriptive study using qualitative and quantitative methods. Subjects participated in an average 30-minute audiotaped interview session consisting of questions pertinent to their perceived level of frustration in communicating and the interventions practitioners used to meet their communication needs. Transcripts were analyzed by question and for overall themes.

RESULTS

It was found that 62% of patients (n = 18) reported a high level of frustration in communicating their needs while being mechanically ventilated. There was no significant difference between the duration of intubation and the level of frustration (Spearman r =.109, P =.573) or between the diagnosis and the level of frustration (P =.932). Patients who received anxiolytics (n = 23, 79% of the sample) had a lower level of frustration (mean 3.26) than those who did not receive anxiolytics (n = 6, 21% of the sample, mean 4.33). This difference trended toward significance (P =.084). Patients cited health care practitioner behaviors, characteristics, and attributes that both facilitated communication (kind, informative, and physically present at the bedside) and impeded their ability to communicate (mechanical, inattentive, and "absent" from the bedside). Patients reported problems and stresses associated with communication difficulties that can be alleviated by the health care practitioner.

CONCLUSIONS

Mechanically ventilated patients experience a high level of frustration when communicating their needs, and health care providers have a significant impact on the mechanically ventilated patient's experience. Further research is needed to explore and measure methods of facilitating communication that increase patient satisfaction, reduce patient anxiety, and obtain optimal pain management.

Reclaiming the everyday world: how long-term ventilated patients in critical care seek to gain aspects of power and control over their environment

Critical care nurses are increasingly seeking to base patient care on evidence derived from research studies. The purpose of this study was to explore the meanings former patients attributed to being on long-term mechanical ventilation in a critical care unit (CCU) in Australia. Using Heideggerian phenomenology, unstructured interviews were undertaken with nine participants. Data were analysed thematically using the method developed by van Manen. Thematic analysis revealed four major themes. This article presents the findings from the theme titled: Reclaiming the everyday world, which describes how the study participants gained comfort from the presence of nurses and their families, sought control over their treatments, and questioned and interpreted the environment, in order to reclaim self. The study highlighted the central role of nurses in patient care, and served as a basis for a number of recommendations, which include recognising the significant role of nurses and family in patient care, and being aware that patients may want more control over their environment and instigate ways to facilitate this. Further research is warranted to examine CCU patients' perceived level of control and power, and to investigate the extent and type of involvement CCU patients would like to have in their care.

Vulnerability and security in seriously ill patients in intensive care

The purpose of this research was to gain an understanding of the experience of being a seriously ill patient in an intensive care unit (ICU). Fourteen former patients, aged 17-71 years old, who had been in ICU 3-53 days, participated in focus group interviews 3-6 months after discharge. The focus groups met 3 times each for 1.5 hours, resulting in 13-14 hours of audiotaped discussions. The transcribed data were qualitatively analysed to identify themes representing participants' experiences. Vulnerability emerged as a central concept that captured the identified themes. The data reveal that patient vulnerability while in ICU was related to extreme physical and emotional dependency. Lack of information and depersonalizing care were associated with fear, anxiety and increased vulnerability. Lack of sleep and rest also contributed to patient fear and anxiety. Vulnerability decreased when patients were kept informed of what was occurring while in ICU, received care that was personalized to their individual needs, and when their families were present. The results of this study suggest that ICU patients' vulnerability may be decreased by the security that they experience when they are adequately informed about what is happening, and when nursing and medical care is personalized to their individual needs.

Self-reported symptom experience of critically ill cancer patients receiving intensive care

OBJECTIVE

To characterize the symptom experience of a cohort of intensive care unit (ICU) patients at high risk for hospital death.

DESIGN

Prospective analysis of patients with a present or past diagnosis of cancer who were consecutively admitted to a medical ICU during an 8-month period.

SETTING

Academic, university-affiliated, tertiary-care, urban medical center.

PATIENTS

One hundred cancer patients treated in a medical ICU.

INTERVENTION

Assessment of symptoms.

MEASUREMENTS

Patients' self-reports of symptoms using the Edmonton Symptom Assessment Scale (ESAS), and ratings of pain or discomfort associated with ICU diagnostic/therapeutic procedures and of stress associated with conditions in the ICU.

MAIN RESULTS

Hospital mortality for the group was 56%. Fifty patients had the capacity to respond to the ESAS, among whom 100% provided symptom reports. Between 55% and 75% of ESAS responders reported experiencing pain, discomfort, anxiety, sleep disturbance, or unsatisfied hunger or thirst that they rated as moderate or severe, whereas depression and dyspnea at these levels were reported by approximately 40% and 33% of responders, respectively. Significant pain, discomfort, or both were associated with common ICU procedures, but most procedure-related symptoms were controlled adequately for a majority of patients. Inability to communicate, sleep disruption, and limitations on visiting were particularly stressful among ICU conditions studied.

CONCLUSIONS

Among critically ill cancer patients, multiple distressing symptoms were common in the ICU, often at significant levels of severity. Symptom assessment may suggest more effective strategies for symptom control and may direct decisions about appropriate use of ICU therapies.

Interpretation of nonvocal behavior and the meaning of voicelessness in critical care

This paper presents two interrelated psychosocial constructs, voicelessness and interpretation, which were derived from a participant observation study of critically ill older adults in the USA. Voicelessness occurs when physiological, psychosocial and/or technological barriers limit the abilities of critically ill patients to represent their thoughts, feelings, desires and needs fully to others. Voicelessness influences not only the responses of critically ill patients to their condition, environment and caregivers, but also profoundly effects the responses of family members and clinicians. Thus, communicative interactions as well as certain clinical and treatment decisions in ICU hinge on clinician and family member interpretation of patients' nonvocal behaviors. Conditions and factors contributing to interpretation are described and a hypothesis proposed, that interpretation mitigates the detrimental effects of voicelessness.

The art and science of predicting patient readiness for weaning from mechanical ventilation

Weaning from mechanical ventilation is attempted when the patient's underlying condition has resolved and when the patient is able to maintain cardiovascular and respiratory stability within normal parameters. From a medical perspective, when to wean is based on patient readiness determined by objective, physiological criteria. Psychological readiness is equally important, yet criteria determining psychological readiness is generally omitted from the list of ready to wean parameters. Reasons for this may be that psychological readiness is difficult to measure and is based upon subjective opinions. Nursing research exploring critical care nurses' and patients' experiences of weaning has extended knowledge concerning patients' psychological readiness to wean. From examination of this research, three important criteria emerge. It is recommended that the addition of these criteria to the list of physiological criteria will not only achieve a holistic assessment of patients' readiness to wean, but will also acknowledge the important and complementary role of the nurse in the weaning process.

The psychological consequences of source isolation: a review of the literature

Source isolation can be an extremely frightening and anxiety provoking experience. With the many epidemiological changes that are prevalent in the UK today the need to care for individuals in source isolation is becoming increasingly important to prevent the spread of infection in hospitals. However, the psychological effects of source isolation are not well understood or researched. This review defines and examines the historical developments of source isolation and then discusses related research which suggests possible effects of source isolation on an individual's psychological well-being. Research which has determined the effects of sensory deprivation and social isolation are discussed, together with literature on the intensive care syndrome. This review highlights the lack of research on the psychological effects of source isolation. Furthermore, literature and research on related aspects of isolation suggests very serious effects are noted on the psychological well-being of individuals. Whilst a cessation of source isolation is not an option, urgent research is required to examine what nurse interventions can be implemented to ameliorate these negative effects.

Factors related to the emotional responses of intubated patients to being unable to speak

OBJECTIVES

The purpose of the study was to examine the relationships among the intensity of intubated patients' negative emotional responses to being unable to speak and selected personal and situational variables.

DESIGN

Prospective correlational.

SETTING

Four intensive care units in a midwestern, university-affiliated medical center.

PATIENTS

A convenience sample of 48 patients intubated for 24 or more hours, alert and oriented to person, place, and situation.

OUTCOME MEASURES

Emotional responses (anger and worry/fear) to being unable to speak.

RESULTS

Multiple regression showed that self-esteem, severity of illness, difficulty with communication, and the number of days intubated at data collection were significantly associated with patients' emotional responses.

CONCLUSIONS

Results from this study extend prior research and support the need for nurses to facilitate communication and to support self-esteem in patients receiving ventilatory assistance, particularly in the early days of intubation. Implications for future research are discussed.

Pain and distress among elderly intensive care unit patients: comparison of patients' experiences and nurses' assessments

OBJECTIVE

To investigate elderly intensive care unit (ICU) patients' experiences of pain and distress, as well as interventions aimed at reducing these conditions, and to compare these experiences with the way nurses and assistant nurses, respectively, assess their patients' responses related to these issues.

DESIGN

Descriptive, correlational, comparative.

SETTING

Two medical-surgical ICUs at county hospitals in two medium-sized cities in Sweden.

SUBJECTS

Fifty-one elderly patients, 44 nurses, and 37 assistant nurses in two Swedish ICUs.

METHODS

Data were collected through personal interviews with patients and questionnaires completed by each nurse and assistant nurse responsible for the patients.

RESULTS

Patients' experiences of pain and distress do not fully agree with nurses' and assistant nurses' assessments; nor is there consistency between the views of nurses and those of assistant nurses. Nurses overestimated patients' breathing and intellectual problems. Assistant nurses assessed that patients received more assistance to relieve physical pain, physical discomfort, fatigue, and fear than patients reported. Compared with nurses' assessments, assistant nurses also perceived patients to suffer less from physical discomfort, breathing problems, and fatigue.

CONCLUSIONS

Nurses need more systematic procedures to assess patients' distress and pain experiences. To reduce the discrepancies observed between nurses and assistant nurses, organization of care should optimize the possibilities for the caregivers to carry out the desired assessments and interventions with a high degree of continuity and communication among staff.

A comparison of patients' communication-related responses during intubation and after extubation

OBJECTIVE

The purpose of this exploratory pilot study was to examine patients' communication-related responses during intubation and after extubation, and to determine whether differences in patients' report of responses at these two points in time, if present, were associated with demographic and situational variables.

DESIGN

Descriptive comparative.

SETTING

Four intensive care units in a midwestern, university-affiliated medical center.

PATIENTS

Convenience sample of 29 patients intubated for 24 or more hours, alert and oriented to person, place, and setting during intubation and after extubation.

OUTCOME MEASURES

Emotional responses (anger and worry/fear) to being unable to speak, perceived difficulty with communication.

RESULTS

Paired t tests showed no significant differences over time in the mean scores of the Emotion subscales and Ease of Communication scale. However, more than 30% of subjects reported postextubation responses that were different from their earlier responses by 20% or more. Significant differences in subjects' worry/fear at being unable to speak and difficulty with communication were found in relation to history of prior intubation and total number of days intubated. Subjects varied in the number of days that they were intubated, and the number of days intubated when they first participated in the study.

CONCLUSIONS

Results provide direction for larger longitudinal prospective and retrospective studies with larger samples that examine patients' recall of their responses during intubation, especially related to communication.

Qualitative analysis of patients' work during mechanical ventilation and weaning

OBJECTIVE

To describe patients' recollections of their experiences during mechanical ventilation and weaning and to extend an evolving nursing theory of weaning.

DESIGN

A qualitative approach that used grounded theory techniques.

PATIENTS AND METHODS

We surveyed 20 hospitalized patients who had recently undergone mechanical ventilation and weaning from the ventilator in a critical care unit. Included in the analysis were any thoughts, feelings, or actions recalled by the patients that were related to the weaning experience.

RESULTS

During ventilation and weaning, patients were engaged to various degrees in what they called "work," which consisted of their efforts to assist in their adjustment and recovery. This work had four themes: sense making, enduring, preserving self, and controlling responses. These themes represented activities by which patients dealt with their personal concerns and cooperated with the therapeutic plan.

CONCLUSIONS

Despite good care during the process, mechanical ventilation and weaning are stressful experiences that require active participation by patients. Patients' work needs to be understood and supported by clinicians to facilitate recovery from mechanical ventilation and weaning.

Patient's experiences of communication during the respirator treatment period

This paper reports a study of the patients' experiences of communication during the respirator treatment period (RT period) in the intensive care unit (ICU). This descriptive and exploratory study was designed to answer the question. How do respirator treated patients experience communication? Eight individuals who had experienced being treated with a respirator in two ICUs in Iceland, took part in audiotape-recorded, open interviews. They described their subjective experiences of communication during the RT period. The descriptions were analysed phenomenologically, using Colaizzi's method, described by Hycner (1985). The results revealed 57 themes within four categories, namely 'the patients' experiences of communication during the RT period', 'problems of communication experienced', 'additional problems of communication experienced' and 'nursing interventions experienced'. In this paper the themes within the categories of the patients' experiences of communication and problems of communication will be reported. The participants remembered their experience of communication clearly. The patients' experiences of communication were generally described as negative; they experienced communication as impaired, which evoked various negative emotions, and sometimes they had the feeling of giving up. Participants generally described being tired or exhausted during the intubation period. They emphasised the importance of the information and explanation provided by the nurses. The presence and support provided by family members was also valuable to them. The results add to the cumulative knowledge base of communication between nurses and patients by generating new meanings of the nature and essences of communication during the RT period from the patients' perspectives. In this article, the findings of the study are described and discussed in relation to earlier published research and clinical literature on the subject.

Addressing Reliability Estimates When the Population is Small: Can Social Cognition Help?

One of the issues facing researchers studying very select populations is how to obtain reliability estimates for their instruments. When the populations and resulting samples of studies are very small and select, gathering data for typical reliability estimates becomes very difficult. As a result, many researchers ignore the concern about reliability of their instrumentation and forge ahead collecting data. In response to this concern, Bandura's model of social cognition and Wolpe's model of systematic desensitization were combined and applied to a group of 90 undergraduates completing a Communication Satisfaction Scale designed to assess the attitudes of intubated patients in a hospital Intensive Care Unit. Stimuli (text, auditory and visual) were provided to sensitize the subjects to the intubation procedure and to enable the subjects to imagine what it is like to be an intubated patient. The subjects responded to 10 items focusing on the communication issues of intubated patients on a scale in Likert format. Internal reliability (Cronbach alpha) was 0.83 for the entire scale. The results are discussed within both a social cognition and a measurement framework. While the resulting reliabilities cannot be directly applied to the intubated sample, the procedure may provide critical feedback to researchers and instrument developers prior to the actual administration of the instrument in research.

Amyotrophic lateral sclerosis and life-sustaining therapy: patients' desires for information, participation in decision making, and life-sustaining therapy

To identify the wishes of patients with amyotrophic lateral sclerosis (ALS) for information, participation in decision making, and life-sustaining therapy and to determine whether these wishes are stable over time, we conducted a prospective survey (baseline and 6-month follow-up interviews) of 38 consecutive patients with an established diagnosis of ALS at the University of Chicago Motor Neuron Disease Clinic. Demographic data, clinical stage of ALS, illness experience, wishes for information, and desires for participating in decisions about life-sustaining therapy were elicited. Patients readily expressed their wishes for specific information on communication aids and ventilator care for respiratory failure. Demographic, socioeconomic, and clinical characteristics did not predict patients' desires for information and decision making. The preferences for information and participation in decisions were stable during the 6-month study period, whereas preferences for cardiopulmonary resuscitation in two hypothetical circumstances were less stable. Changes were unrelated to demographic or clinical characteristics of the patients. Because many patients with ALS change their preferences for life-sustaining therapy, advance directives for end-of-life care must be reevaluated periodically.

Families and intensive care nurses: comparison of perceptions

This study compared family members' and nurses' perceptions on families' needs when a relative was hospitalized in an intensive care unit (ICU). Family members (N = 32) and nurses (N = 23) complete equivalent 44-item questionnaires. Both family members and nurses agreed that the greatest needs of families were anxious at admission (P less than 0.05). Families and nurses seemed satisfied in the Participation/Information and Emotional Support categories, but more disagreements were noted in these areas. More nurses perceived families as not wanting to participate in patient care (P less than 0.003), felt that families did not have enough time to visit (P less than 0.004), believed that families were comfortable expressing their feelings (P less than 0.02) but thought families were uncomfortable asking questions (P less than 0.01). It was concluded that families be prepared for the patient's condition and appearance, and for the hospital milieu in order to cope more effectively with excessive stress in time of crisis. Concordance in perceived needs of family members and care providers may lead to greater need satisfaction and it is advocated that both the patient and the family (rather than the patient alone) be the focus of treatment because of the relationship between social support and patient recovery.
