Patients in a permanent vegetative state or minimally conscious state in the Maine-et-Loire county of France: A cross-sectional, descriptive study

Prevalence of the Minimally Conscious State Among Institutionalized Patients in the Netherlands: A Nationwide Study

BACKGROUND AND OBJECTIVES

The minimally conscious state (MCS) is a prolonged disorder of consciousness (pDoC) and one of the most severe outcomes of acquired brain injury. Prevalence data are scarce. The aim of this study was to establish the nationwide point prevalence of institutionalized patients in MCS in the Netherlands.

METHODS

This was a descriptive cross-sectional study in which all 86 Dutch hospitals, all 5 specialized pDoC rehabilitation facilities, and all 274 nursing homes were asked whether they were treating patients with a pDoC on the point prevalence date of September 15, 2021. Each patient's legal representative provided informed consent for their inclusion. Patient level of consciousness was verified using the Coma Recovery Scale-Revised (CRS-R) in a single assessment session performed in the facility of residence by an experienced physician. Data on patient demographics, etiology, level of consciousness, facility of residence, and clinical status were collected from a questionnaire by the treating physician. The prevalence of institutionalized patients in MCS of per 100,000 members of the Dutch population was calculated, based on actual census data.

RESULTS

Seventy patients were reported to have a pDoC, of whom 6 were excluded. The level of consciousness was verified for 49 patients while for 15, it could not be verified. Of the patients verified, 38 had a pDoC, of whom 32 were in MCS (mean age 44.8 years, 68.8% male). The prevalence of institutionalized patients in MCS is 0.2-0.3 per 100,000 Dutch inhabitants. Traumatic brain injury was present in 21 of 32 patients (65.6%). Specialized pDoC rehabilitation was received by 17 of 32 patients (53%), with the rest admitted to nursing homes. The most frequent signs of consciousness on the CRS-R were visual pursuit, reproducible movement to command, and automatic motor response.

DISCUSSION

This nationwide study revealed a low prevalence of institutionalized patients in MCS in the Netherlands. These findings are now being used to organize pDoC care in this country.

Informal Caregivers of Patients with Disorders of Consciousness: a Qualitative Study of Communication Experiences and Information Needs with Physicians

Due to improvements in medicine, the figures of patients with disorders of consciousness (DoC) are increasing. Diagnostics of DoC and prognostication of rehabilitation outcome is challenging but necessary to evaluate recovery potential and to decide on treatment options. Such decisions should be made by doctors and patients’ surrogates based on medico-ethical principles. Meeting information needs and communicating effectively with caregivers as the patients´ most common surrogate-decision makers is crucial, and challenging when novel tech-nologies are introduced. This qualitative study aims to explore information needs of informal DoC caregivers, how they manage the obtained information and their perceptions and experiences with caregiver-physician communication in facilities that implemented innovative neurodiagnostics studies. In 2021, we conducted semi-structured interviews with nine caregivers of clinically stable DoC patients in two rehabilitation centers in Italy and Germany. Participants were selected based on consecutive purposeful sampling. Caregivers were recruited at the facilities after written informed consent. All interviews were recorded, transcribed verbatim and translated. For analysis, we used reflexive thematic analysis according to Braun & Clarke (2006). Caregivers experienced the conversations emotionally, generally based on the value of the information provided. They reported to seek positive information, comfort and empathy with-in the communication of results of examinations. They needed detailed information to gain a deep understanding and a clear picture of their loved-one’s condition. The results suggest a mismatch between the perspectives of caregivers and the perspectives of medical profession-als, and stress the need for more elaborate approaches to the communication of results of neu-rodiagnostics studies.

Patients in permanent vegetative or minimally conscious states: A literature review of the psychological and health impacts on healthcare personnel

BACKGROUND

To address the quality of life of patients in Permanent Vegetative or Minimally Conscious States, the occupational health of those around them must also be taken into account.

OBJECTIVE

By analyzing how the available scientific literature has addressed this issue, this study seeks to better understand how caring for these patients affects healthcare professionals' psychological and health status.

METHODS

We identified and selected 15 publications from both Anglophone and Francophone databases, i.e., Cairn, Francis, HAL, PsycINFO, PubMed, ResearchGate and ScienceDirect.

RESULTS

The reviewed publications and studies highlight the difficulties healthcare professionals face with regard to the relationship with patients and their families. Two studies in particular suggest that the difficulties these professionals experience daily can lead to burnout. Other potential burnout factors include the healthcare profession category, the work environment, lack of training and the time spent working with this specific group of patients.

CONCLUSIONS

Our literature review highlights the institutional and personal resources that may prevent these occupational risks. It also provides avenues for future research.

Profiling the Characteristics of People Who Are Comatose in Long-term and Complex Continuing Care Settings

OBJECTIVES

To describe the sociodemographic, clinical, and treatment characteristics of people who are comatose in Canadian complex continuing care (CCC) and long-term care (LTC) settings, and to make recommendations to promote comprehensive care planning for this population.

DESIGN

Retrospective, cross-sectional analysis of population data.

SETTING AND PARTICIPANTS

All residents in the Canadian provinces of Alberta, Ontario, British Columbia, Manitoba, Nova Scotia, Newfoundland, Saskatchewan, and the territory of Yukon with data available from the fiscal year 2015 (April 1, 2015, to March 31, 2016).

MEASURES

Demographic, clinical, and treatment variables were extracted from the Resident Assessment Instrument-Minimum Data Set (MDS 2.0) and were reported using descriptive statistics.

RESULTS

Of the LTC and CCC populations, 0.07% and 3.5% were identified as comatose, respectively. Overall, people who are comatose in both CCC or LTC settings are younger and have a longer length of stay than those who are not comatose. A higher proportion of people who are comatose experience active infections and irregular bowel elimination patterns, and those who are comatose were more likely to have a feeding tube and require oxygen therapy or suctioning than those who were not comatose. However, a lower proportion of people who were comatose had documented pain. In LTC, one-quarter of people who are comatose are expected to die within 6 months.

CONCLUSION/IMPLICATIONS

Although the prevalence of people who are comatose in LTC and CCC settings is low, this population is complex and has significant care needs that require comprehensive assessment and care planning.

The Resilient Care of Patients with Vegetative State at Home: a Grounded Theory

Introduction: The care of patients in vegetative state at home is difficult because they need continuous medical interventions and extensive care. The present study aims to explain the process of home care of patients in vegetative state at home.

Methods: This study was a qualitative research with a grounded theory approach. The participants were 22 people (included 17 family caregivers and 5 professional caregivers) who were enrolled in a purposive sampling. Data was gathered through unstructured interviews, observations and field notes. Data collection was continued to saturation. Data analysis was performed through the Strauss and Corbin 1998 approach. The MAXQDA10 software was used to facilitate data analysis.

Results: The data analysis led to emerge four main concepts included "erosive care", "erosive expenditures", "seeking solver education" and "lasting hope" as the axes of the study. Participants' experiences showed that the main concern of family caregivers of vegetative patients was "playing an inevitable role in care", in which they did not hesitate to make any effort, and they tolerated all the problems and issues. Therefore, "resilient care" was extracted as the underlying idea of this study.

Conclusion: The process of resilient care of vegetative patients at home showed planning by policy makers in health system is very important and underscored the necessity for supporting families and family caregivers of these patients. So some changes in the health system for this goal might include considering home care and supporting them in various aspects, especially information, financial and emotional dimensions.

How many patients in a prolonged disorder of consciousness might need a best interests meeting about starting or continuing gastrostomy feeding?

OBJECTIVE:

To estimate the number of people in a prolonged disorder of consciousness (PDOC) who may need a formal best interests decision-making process to consider starting and/or continuing life-sustaining treatment each year in the population of a developed country.

METHOD:

Identification of studies on people with a PDOC giving information about incidence, and/or prevalence, and/or cause, and/or location of long-term care. Sources included systematic reviews, a new search of MEDLINE (April 2018), and a personal collection of papers. Validating information was sought from existing data on services.

RESULTS:

There are few epidemiologically sound studies, most having bias and/or missing information. The best estimate of incidence of PDOC due to acute onset disease is 2.6/100,000/year; the best estimate of prevalence is between 2.0 and 5.0/100,000. There is evidence that prevalence in the Netherlands is about 10% of that in other countries. The commonest documented causes are cerebral hypoxia, stroke, traumatic brain injury, and tumours. There is some evidence suggesting that dementia is a common cause, but PDOC due to progressive disorders has not been studied systematically. Most people receive long-term care in nursing homes, but a significant proportion (10%-15%) may be cared for at home.

CONCLUSION:

Each year, about 5/100,000 people will enter a prolonged state of unconsciousness from acute onset and progressive brain damage; and at any one time, there may be 5/100,000 people in that state. However, the evidence is very limited in quality and quantity. The numbers may be greater.

RECAPDOC - a questionnaire for the documentation of rehabilitation care utilization in individuals with disorders of consciousness in long-term care in Germany: development and pretesting

BACKGROUND

A multitude of different rehabilitation interventions and other specific health care services are offered for individuals with disorders of consciousness in long-term care settings. To investigate the association of those services and patient-relevant outcomes, a specific instrument to document the utilization of those services is needed. The purpose of this study was to develop such a questionnaire administered to caregivers in epidemiological studies or patient registries in Germany.

METHODS

The development process of the RECAPDOC questionnaire was carried out in three steps. Step 1 consisted of a systematic literature review and an online-based expert survey to define the general content. Step 2 was an expert interview to evaluate the preliminary content of the questionnaire. Step 3 was a pretest including cognitive interviews with caregivers. After each step, the results were combined into a new version of the questionnaire.

RESULTS

The first version of the questionnaire included items on utilization of medical care, medical aids, nursing and therapeutic care. The results of the expert interview led to the integration of five new items and the modification of six other items. The pretest led to some minor modifications of the questionnaire since it was rated as feasible and acceptable. The final questionnaire consisted of 29 items covering the domains "living situation", "social insurance status", "utilisation of home health care", "domestic services", "outpatient health care", "specific diagnostic measures", "adaptive technologies", "medical aids" and "utilization of therapies". Also the experience of family support and multidisciplinary collaboration of health professionals is covered.

CONCLUSIONS

The developed questionnaire is a first step to make the situation of patients with disorders of consciousness in the long-term care setting accessible for evaluation in epidemiological studies and in the context of patient registries. However, further reliability and validity studies are needed.

Care pathways models and clinical outcomes in Disorders of consciousness

OBJECTIVE

Patients with Disorders of consciousness, are persons with extremely low functioning levels and represent a challenge for health care systems due to their high needs of facilitating environmental factors. Despite a common Italian health care pathway for these patients, no studies have analyzed information on how each region have implemented it in its welfare system correlating data with patients' clinical outcomes.

MATERIALS AND METHODS

A multicenter observational pilot study was realized. Clinicians collected data on the care pathways of patients with Disorder of consciousness by asking 90 patients' caregivers to complete an ad hoc questionnaire through a structured phone interview. Questionnaire consisted of three sections: sociodemographic data, description of the care pathway done by the patient, and caregiver evaluation of health services and information received.

RESULTS

Seventy-three patients were analyzed. Length of hospital stay was different across the health care models and it was associated with improvement in clinical diagnosis. In long-term care units, the diagnosis at admission and the number of caregivers available for each patient (median value = 3) showed an indirect relationship with worsening probability in clinical outcome. Caregivers reported that communication with professionals (42%) and the answer to the need of information were the most critical points in the acute phase, whereas presence of Non-Governmental Organizations (25%) and availability of psychologists for caregivers (21%) were often missing during long-term care. The 65% of caregivers reported they did not know the UN Convention on the Rights of Persons with Disabilities.

CONCLUSION

This study highlights relevant differences in analyzed models, despite a recommended national pathway of care. Future public health considerations and actions are needed to guarantee equity and standardization of the care process in all European countries.

Acupuncture Reduces Excitability of Spinal Motor Neurons in Patients with Spastic Muscle Overactivity and Chronic Disorder of Consciousness Following Traumatic Brain Injury

BACKGROUND AND OBJECTIVE

Spastic hypertonia usually occurs in patients with chronic disorders of consciousness (DOC) following severe traumatic brain injury (TBI). Spinal motor neuron excitability has been reported to increase in patients with brain damage. The aim of this study was to evaluate the immediate effects of acupuncture on spinal motor neuron excitability in patients with DOC following TBI by using evoked electromyography.

SETTING AND PARTICIPANTS

Eleven male patients (mean age, 33 ± 14 years) with refractory muscle spasticity of the upper extremity accompanying chronic DOC following TBI and admitted to Chubu Medical Center for Prolonged Traumatic Brain Dysfunction were included.

DESIGN

A crossover study design was used. Changes in variables in the acupuncture session were compared with those in the control session in the same patients.

INTERVENTION

Acupuncture treatment was performed at GV 26, Ex-HN 3, bilateral LI 4, and ST 36 for 10 minutes.

OUTCOME MEASURES

F-wave was recorded from the abductor pollicis brevis muscle. The main outcome measure was F/M amplitude ratio (F-wave amplitude/M-wave amplitude), calculated as an index for spinal motor neuron excitability. F-waves were recorded before treatment (baseline), 10 minutes after needle insertion (phase 1), and 10 minutes after needle removal (phase 2). The same procedure was followed in the control session without acupuncture on a separate day.

RESULTS

F/M ratio was significantly reduced from baseline to phase 1 (p < 0.001) and phase 2 (p < 0.001) in the acupuncture session, whereas no significant changes were observed in the control session. Changes in F/M ratio from baseline to phase 1 and phase 2 were greater in the acupuncture session than the control session (p = 0.001 and <0.001, respectively).

CONCLUSION

The excitability of the spinal motor neurons in patients with DOC following TBI was reduced after acupuncture treatment, suggesting that it is beneficial for reducing spastic muscle hypertonia in these patients.

Multiple Victims: The Result of Caring Patients in Vegetative State

Background:

Having a patient in a vegetative state in the family is a complicated and stressful experience. Caring for such patients with complete disability at home is very challenging.

Objectives:

The present study aimed to explore the outcomes of caring for patients in a vegetative state for families and caregivers at home.

Patients and Methods:

In this qualitative study, 16 vegetative patients’ caregivers were selected through purposive sampling. Unstructured interviews and observations were used for data gathering. Data collection was continued until saturation of data and emergence of the main themes. Data analysis was performed by the content analysis method.

Results:

The analysis of the gathered data led to three themes: “lost main caregiver”, “affected caring partner” and “affected family”. Each theme had some subthemes and subcategories.

Conclusions:

The three emerged themes in this study showed that all the family members of vegetative patients, depending on their responsibilities, were affected by physical, mental, social and economic issues.

Vita tua, mors mea: The experience of family caregivers of patients in a vegetative state

This study aims to understand whether, and possibly how, caregivers of patients in a vegetative state experience an emotional paradox between life and death. Individual semi-structured interviews were conducted with 24 (19 females and 5 males) caregivers of vegetative state patients living in northern Italy. Data were analysed using interpretative phenomenological analysis. Caregivers felt they were the only ones able to understand and give answer to patients' needs, but neglected their own lives in their total commitment to the patient. The findings highlight the importance for vegetative state caregivers in considering new possibilities of life that go beyond the assistance of vegetative state patients.

The vegetative state/unresponsive wakefulness syndrome: a systematic review of prevalence studies

One of the worst outcomes of acquired brain injury is the vegetative state, recently renamed 'unresponsive wakefulness syndrome' (VS/UWS). A patient in VS/UWS shows reflexive behaviour such as spontaneous eye opening and breathing, but no signs of awareness of the self or the environment. We performed a systematic review of VS/UWS prevalence studies and assessed their reliability. Medline, Embase, the Cochrane Library, CINAHL and PsycINFO were searched in April 2013 for cross-sectional point or period prevalence studies explicitly stating the prevalence of VS/UWS due to acute causes within the general population. We additionally checked bibliographies and consulted experts in the field to obtain 'grey data' like government reports. Relevant publications underwent quality assessment and data-extraction. We retrieved 1032 papers out of which 14 met the inclusion criteria. Prevalence figures varied from 0.2 to 6.1 VS/UWS patients per 100 000 members of the population. However, the publications' methodological quality differed substantially, in particular with regards to inclusion criteria and diagnosis verification. The reliability of VS/UWS prevalence figures is poor. Methodological flaws in available prevalence studies, the fact that 5/14 of the studies predate the identification of the minimally conscious state (MCS) as a distinct entity in 2002, and insufficient verification of included cases may lead to both overestimation and underestimation of the actual number of patients in VS/UWS.

Changes over time in the quality of life, prolonged grief and family strain of family caregivers of patients in vegetative state: A pilot study

This study explored changes over time and in the internal standards of the quality of life, prolonged grief and family strain of informal caregivers of patients in vegetative state. Data obtained from 52 caregivers showed high levels of prolonged grief and family strain, and low quality of life. A decrease of caregivers’ quality of life and an increase of family strain were found by adopting a response shift procedure. Only prolonged grief did not change during time. Clinical intervention with the caregivers of vegetative state patients should be differentiated on the basis of the duration of the caring experience.

Caregivers of patients with disorders of consciousness: coping and prolonged grief

OBJECTIVES

To study the relationship between coping strategies and prolonged grief disorder (PGD) in caregivers of patients with disorders of consciousness: vegetative state (VS) or minimally conscious state (MCS).

MATERIALS AND METHODS

Fifty-three caregivers of 43 patients with VS or MCS were assessed using PG-12 and Brief COPE-28. Mean differences for each coping strategy between caregivers of patients with/without PGD were compared using Bonferroni-adjusted t-tests, and the size effect was calculated (Cohen's d).

RESULTS

The frequency of PGD was very high (n = 32; 60.40%). The most common coping strategies were problem-focused: active coping (mean = 6.41; SD = 1.02), Instrumental support (mean = 6.41; SD = 1.06), Planning (mean = 6.32; SD = 1.01) and Acceptance (mean = 6.20; SD = 1.29). Acceptance predicted a lower presence of PGD (P = 0.001; Cohen's d = 1.02), while Denial (P = 0.003; Cohen's d = 0.98) and Self-blame (P = 0.004, Cohen's d = 0.91) increased the presence of PGD.

CONCLUSIONS

The caregivers of patients with VS or MCS show a high risk of PGD. Problem-focused coping strategies are the most used. Acceptance is highly protective of PGD, and Denial and Self-blame are associated with an increased presence of PGD. PGD in caregivers of patients in VS or MCS should be evaluated, Acceptance and problem-focused strategies should be promoted, and Denial and Self-blame should be diminished.

Opportunity for inpatient brain injury rehabilitation for persons in a vegetative state: survey of Swedish physicians

OBJECTIVE

: The aim of this study was to document physicians' opinions on inpatient rehabilitation care for working-age patients in vegetative state after new acquired brain injury, given the absence of an established standard of post-acute care.

DESIGN

: A postal survey of 3259 Swedish physicians was conducted.

RESULTS

: Survey response rate was 33%. Of survey respondents, 51% reported that they knew the definition of vegetative state. Transfer of vegetative patients from acute care to inpatient rehabilitation was considered always warranted by 54% and never or only sometimes warranted by 31% of survey respondents, whereas 15% did not know or did not answer. Rehabilitation physicians most often considered an inpatient rehabilitation stay of around 3 mos to be appropriate, but there was a lack of consensus. Discharge from acute care direct to social care at least sometimes was reported by 39% of physicians.

CONCLUSIONS

: Physicians' opinions vary considerably on appropriate post-acute care for patients in vegetative state after acquired brain injury. This may impact on rates of referral and admission to rehabilitation units. Consensus is needed on a minimum period for and extent of rehabilitation interventions. Educational interventions should be targeted broadly to reach the wide range of specialties that may have responsibility for acute care of these patients.
