Sex Differences in Patients with Chronic Pain Following Whiplash Injury: The Role of Depression, Fear, Somatization, Social Support, and Personality Traits.

BACKGROUND: Chronic whiplash-associated disorders (chronic WAD) cover a large variety of clinical manifestations that can occur after a whiplash injury. Women have an increased risk of developing chronic WAD, and it is suggested that psychosocial factors are related to long-term pain and functioning following whiplash injury and persistence of chronic pain. This leads to the question whether there are sex differences in psychosocial factors in chronic WAD. METHODS: This study included 117 subjects who had experienced a whiplash injury at least 3 months before the start of the study (mean duration of pain: 67.29 ± 63.86 months, range: 297 months). They were selected as chronically symptomatic, by excluding those who had recovered from their whiplash injury. Psychosocial aspects (including depression, fear, somatization, social support, and personality traits) were assessed by validated questionnaires, and sex differences were tested using a univariate analysis of variance (ANCOVA), with age and time from whiplash injury as covariates. RESULTS: No differences in depression, fear, somatization, discrepancy in social support personality trait, Neck Disability Index scores, physical functioning, bodily pain, or general health were present between women and men with chronic WAD. Women with chronic WAD reported higher levels of emotional support in problem situations and social companionship. CONCLUSION: Except for emotional support in problem situations and social companionship, psychosocial factors do not differ between men and women with chronic WAD. These findings imply little to no risk for sex bias in studies investigating psychosocial issues in patients with chronic WAD.

Recruitment bias in chronic pain research: whiplash as a model.

In science findings which cannot be extrapolated to other settings are of little value. Recruitment methods vary widely across chronic whiplash studies, but it remains unclear whether this generates recruitment bias. The present study aimed to examine whether the recruitment method accounts for differences in health status, social support, and personality traits in patients with chronic whiplash-associated disorders (WAD). Two different recruitment methods were compared: recruiting patients through a local whiplash patient support group (group 1) and local hospital emergency department (group 2). The participants (n=118) filled in a set of questionnaires: the Neck Disability Index, Medical Outcome Study Short-Form General Health Survey, Anamnestic Comparative Self-Assessment measure of overall well-being, Symptom Checklist-90, Dutch Personality Questionnaire, and the Social Support List. The recruitment method (either through the local emergency department or patient support group) accounted for the differences in insufficiency, somatization, disability, quality of life, self-satisfaction, and dominance (all p values <.01). The recruitment methods generated chronic WAD patients comparable for psychoneurotism, social support, self-sufficiency, (social) inadequacy, rigidity, and resentment (p>.01). The recruitment of chronic WAD patients solely through patient support groups generates bias with respect to the various aspects of health status and personality, but not social support. In order to enhance the external validity of study findings, chronic WAD studies should combine a variety of recruitment procedures.

Continuous deep sedation until death in Belgium: a survey among nurses.

CONTEXT: Continuous deep sedation (CDS) is a subject of important debate, but until now nurses have rarely been questioned about their involvement and perceptions. OBJECTIVES: To study the communication process between nurses and patients, relatives, or physicians before starting CDS, and how nurses perceive this end-of-life practice. METHODS: In 2007, we surveyed 1678 nurses in Flanders, Belgium, who, in an earlier survey, had reported caring for one or more patients who received an end-of-life decision within the previous year. Nurses were surveyed about their most recent case. RESULTS: The response rate was 75.8%: 250 nurses reported a case of CDS (64.4% hospital, 18.4% home, and 17.2% nursing home). In, respectively, 25.8% and 75.4%, the patient and relatives had communicated with the nurse about the CDS. In 17.6%, there was no communication between the nurse and the physician about the CDS; in 29.1%, the physician and nurse only exchanged information; and in 23.4%, they made the decision jointly. Making the decision jointly was associated with a more positive evaluation of the cooperation with the physician (adjusted odds ratio 10.9 and 95% confidence interval 3.0, 39.2). Nurses perceived CDS as partly intended to hasten death partially in 48.4% and explicitly in 28.4% of cases, estimating possible or certain life shortening in 95.6%. CONCLUSION: Nurses in different health care settings are often involved in communication about CDS. They see it mainly as a practice intended to hasten death, with a life-shortening effect; guidelines should recommend clear discussions between caregivers in which the physician states the purpose and estimated effect of the decision.

Long-term functioning following whiplash injury: the role of social support and personality traits.

Transition from acute whiplash injury to either recovery or chronicity and the development of chronic whiplash-associated disorders (WAD) remains a challenging issue for researchers and clinicians. The roles of social support and personality traits in long-term functioning following whiplash have not been studied concomitantly. The present study aimed to examine whether social support and personality traits are related to long-term functioning following whiplash. One hundred forty-three subjects, who had experienced a whiplash injury in a traffic accident 10-26 months before the study took place, participated. The initial diagnoses were a 'sprain of the neck' (ICD-9 code 847.0); only the outcome of grades I-III acute WAD was studied. Long-term functioning was considered within the biopsychosocial model: it was expressed in terms of disability, functional status, quality of life and psychological well-being. Participants filled out a set of questionnaires to measure the long-term functioning parameters (i.e. the Neck Disability Index, Medical Outcome Study Short-Form General Health Survey, Anamnestic Comparative Self-Assessment measure of overall well-being and the Symptom Checklist-90) and potential determinants of long-term functioning (the Dutch Personality Questionnaire and the Social Support List). The results suggest that social support (especially the discrepancies dimension of social support) and personality traits (i.e. inadequacy, self-satisfaction and resentment) are related to long-term functioning following whiplash injury (Spearman rho varied between 0.32 and 0.57; p < 0.01). Within the discrepancy dimension, everyday emotional support, emotional support during problems, appreciative support and informative support were identified as important correlates of long-term functioning. Future prospective studies are required to confirm the role of social support and personality traits in relation to long-term functioning following whiplash. For such studies, a broad view of long-term functioning within the biopsychological model should be applied.

The role of nurses in physician-assisted deaths in Belgium.

BACKGROUND: Belgium's law on euthanasia allows only physicians to perform the act. We investigated the involvement of nurses in the decision-making and in the preparation and administration of life-ending drugs with a patient's explicit request (euthanasia) or without an explicit request. We also examined factors associated with these deaths. METHODS: In 2007, we surveyed 1678 nurses who, in an earlier survey, had reported caring for one or more patients who received a potential life-ending decision within the year before the survey. Eligible nurses were surveyed about their most recent case. RESULTS: The response rate was 76%. Overall, 128 nurses reported having cared for a patient who received euthanasia and 120 for a patient who received life-ending drugs without his or her explicit request. Respectively, 64% (75/117) and 69% (81/118) of these nurses were involved in the physician's decision-making process. More often this entailed an exchange of information on the patient's condition or the patient's or relatives' wishes (45% [34/117] and 51% [41/118]) than sharing in the decision-making (24% [18/117] and 31% [25/118]). The life-ending drugs were administered by the nurse in 12% of the cases of euthanasia, as compared with 45% of the cases of assisted death without an explicit request. In both types of assisted death, the nurses acted on the physician's orders but mostly in the physician's absence. Factors significantly associated with a nurse administering the life-ending drugs included being a male nurse working in a hospital (odds ratio [OR] 40.07, 95% confidence interval [CI] 7.37-217.79) and the patient being over 80 years old (OR 5.57, 95% CI 1.98-15.70). INTERPRETATION: By administering the life-ending drugs in some of the cases of euthanasia, and in almost half of the cases without an explicit request from the patient, the nurses in our study operated beyond the legal margins of their profession.

Medical end-of-life decisions: experiences and attitudes of Belgian pediatric intensive care nurses.

OBJECTIVE: To investigate Belgian pediatric intensive care nurses' involvement in and attitudes toward medical end-of-life decisions with a possible or certain life-shortening effect. METHODS: Questionnaires were distributed to 141 nurses working in 5 of the 7 pediatric intensive care units in Belgium. Nurses were asked to recall the last child in their care whose treatment involved an end-of-life decision and to describe anonymously their involvement in the decision. Attitudes were ascertained by means of statements and a Likert scale. RESULTS: Questionnaires were completed by 89 nurses (63%). During the preceding 2 years, 76 (85%) had cared for at least 1 child for whom a medical end-of-life decision had been made. Nurses were involved in initiating the decision in 17% of cases, participated in decision making in 50%, and played a role in carrying out the decision in 90%. Only 6% of nurses found it always ethically wrong to hasten the death of a child by administering lethal drugs; most nurses (78%) reported they were prepared to cooperate in administering life-ending drugs in some cases. Most (89%) favored adapting the law, making life termination of children legally possible in certain cases. CONCLUSIONS: Belgian pediatric intensive care nurses are often involved in carrying out medical end-of-life decisions, including administration of life-ending drugs, whereas their participation in decision making is more limited. Most think that the current euthanasia law should be extended to minors so that administering life-ending drugs would be possible for terminally ill children in specific circumstances.

Attitudes of nurses towards euthanasia and towards their role in euthanasia: a nationwide study in Flanders, Belgium.

BACKGROUND: Nurses have an important role in caring for terminally ill patients. They are also often involved in euthanasia. However, little is known about their attitudes towards it. OBJECTIVES: To investigate on a nationwide level nurses' attitudes towards euthanasia and towards their role in euthanasia, and the possible relation with their socio-demographic and work-related characteristics. DESIGN AND PARTICIPANTS: A cross-sectional design was used. In 2007, a questionnaire was mailed to a random sample of 6000 of the registered nurses in Flanders, Belgium. Response rate was 62.5% and after exclusion of nurses who had no experiences in patient care, a sample of 3321 nurses remained. METHODS: Attitudes were attained by means of statements. Logistic regression models were fitted for each statement to determine the relation between socio-demographic and work-related characteristics and nurses' attitudes. RESULTS: Ninety-two percent of nurses accepted euthanasia for terminally ill patients with extreme uncontrollable pain or other distress, 57% accepted using lethal drugs for patients who suffer unbearably and are not capable of making decisions. Seventy percent believed that euthanasia requests would be avoided by the use of optimal palliative care. Ninety percent of nurses thought nurses should be involved in euthanasia decision-making. Although 61% did not agree that administering lethal drugs could be a task nurses are allowed to perform, 43% would be prepared to do so. Religious nurses were less accepting of euthanasia than non-religious nurses. Older nurses believed more in palliative care preventing euthanasia requests and in putting the patient into a coma until death as an alternative to euthanasia. Female and home care nurses were less inclined than male and hospital and nursing home nurses to administer lethal drugs. CONCLUSIONS: There is broad support among nurses for euthanasia for terminally ill patients and for their involvement in consultancy in case of euthanasia requests. There is, however, uncertainty about their role in the performance of euthanasia. Guidelines could help to make their role more transparent, taking into account the differences between health care settings.

Factors related to the involvement of nurses in medical end-of-life decisions in Belgium: a death certificate study.

BACKGROUND: Although nurses play an important role in end-of-life care for patients, they are not systematically involved in end-of-life decisions with a possible or certain life-shortening effect (ELDs). Until now we know little about factors relating to the involvement of nurses in these decisions. OBJECTIVE: To explore which patient- and decision-characteristics are related to the consultation of nurses and to the administering of life-ending drugs by nurses in actual ELDs in institutions and home care, as reported by physicians. METHOD: We sampled at random 5005 of all registered deaths in the second half of 2001--before euthanasia was legalized--in Flanders, Belgium. We mailed anonymous questionnaires to physicians who signed the death certificates and asked them to report on ELDs, including nurses' involvement. RESULTS: Response rate was 59% (n=2950). Physicians reported nurses involved in decision making more often in institutions than at home, and more often in care homes for the elderly than in hospitals (OR 1.70, 95% CI 1.15, 2.52). This involvement was more frequently when physicians intended to hasten the patient's death than when they had no such intention (institutions: OR 2.05, 95% CI 1.41, 2.99; home: OR 2.04, 95% CI 1.19, 3.49). In institutions, this involvement was also more likely where patients were of lower rather than higher education (OR 2.95, 95% CI 1.49, 5.84). The administering of life-ending drugs by nurses, as reported by physicians was also found more frequently in institutions than at home, and in institutions more frequently with lower rather than higher educated patients (p=.037). CONCLUSIONS: These findings raise questions about physicians' perception of the nurse's role in ELDs, but also about physicians' skills in interacting with all patients. Education and guidelines for physicians and nurses are needed to optimize good communication and to promote a clearer assignment of responsibilities concerning the execution of those decisions.
