Are neck flexion, neck rotation, and sitting at work risk factors for neck pain? Results of a prospective cohort study.

OBJECTIVE: To study the relation between neck pain and work related neck flexion, neck rotation, and sitting. METHODS: A prospective cohort study was performed with a follow up of 3 years among 1334 workers from 34 companies. Work related physical load was assessed by analysing objectively measured exposure data (video recordings) of neck flexion, neck rotation, and sitting posture. Neck pain was assessed by a questionnaire. Adjustments were made for various physical factors that were related or not related to work, psychosocial factors, and individual characteristics. RESULTS: A significant positive relation was found between the percentage of the working time in a sitting position and neck pain, implying an increased risk of neck pain for workers who were sitting for more than 95% of the working time (crude relative risk (RR) 2.01, 95% confidence interval (95% CI) 1.04 to 3.88; adjusted RR 2.34, 95% CI 1.05 to 5.21). A trend for a positive relation between neck flexion and neck pain was found, suggesting an increased risk of neck pain for people working with the neck at a minimum of 20 degrees of flexion for more than 70% of the working time (crude RR 2.01, 95% CI 0.98 to 4.11; adjusted RR 1.63, 95% CI 0.70 to 3.82). No clear relation was found between neck rotation and neck pain. CONCLUSION: Sitting at work for more than 95% of the working time seems to be a risk factor for neck pain and there is a trend for a positive relation between neck flexion and neck pain. No clear relation was found between neck rotation and neck pain.

The effectiveness of quality systems in nursing homes: a review.

BACKGROUND: The need for quality improvement and increasing concern about the costs and appropriateness of health care has led to the implementation of quality systems in healthcare organisations. In addition, nursing homes have made significant investments in their development. The effects of the implementation of quality systems on health related outcomes are not yet clear. OBJECTIVE: To examine evidence in the literature on whether quality systems have an impact on the care process and the satisfaction and health outcomes of long term care residents. METHODS: Review of the literature. RESULTS: The 21 empirical studies identified concerned quality system activities such as the implementation of guidelines; providing feedback on outcomes; assessment of the needs of residents by means of care planning, internal audits and tuition; and an ombudsman for residents. Only four articles described controlled studies. The selected articles were grouped according to five focal areas of quality. The opinion of residents was seldom used to evaluate the effectiveness of quality systems. The effects on care processes and the health outcomes of long term care residents were inconsistent, but there was some evidence from the controlled studies that specific training and guidelines can influence the outcomes at the patient level. CONCLUSIONS: The design of most of the studies meant that it was not possible to attribute the results entirely to the newly implemented quality system. As it is difficult in practice to design a randomised controlled study, future research into the effectiveness of quality systems should not only focus on selected correlates of quality, but should also include a qualitative and quantitative (multivariate and multilevel) approach. The methods used to measure quality need to be improved.

Long-term effectiveness of a quality improvement program for patients with type 2 diabetes in general practice.

OBJECTIVE: To assess the long-term effectiveness of a quality improvement program on care provided and patient outcomes in patients with diabetes. RESEARCH DESIGN AND METHODS: A nonrandomized trial was performed with 312 patients with type 2 diabetes in the intervention group and 77 patients with type 2 diabetes in the reference group. The follow-up period was 42 months. The quality improvement program focused on improving both the provision of diabetes care and the patient outcomes. The program consisted of clinical practice guidelines, postgraduate education, audit and feedback, templates to register diabetes care, and a recall system. Data on the care provided were abstracted from medical records. Main outcomes on the provision of care were annual number of patient visits, blood pressure, and HbA(1c) and blood lipid levels. Main patient outcomes were blood pressure and HbA(1c) and blood lipid levels. Multilevel analysis was used to adjust for dependency between repeated observations within one patient and for clustering of patients within general practices. RESULTS: Patients in the intervention group received care far more in accordance with the guidelines than patients in the reference group. Odds ratios ranged from 2.43 (95% CI 1.01-5.82) for the measurement of urine albumin to 12.08 (4.70-31.01) for the measurement of blood pressure. No beneficial effect was found on any patient outcome. CONCLUSIONS: The quality improvement program improved the provision of diabetes care, but this was not accompanied by any effect on patient outcomes.

Clinical problems with the performance of euthanasia and physician-assisted suicide in The Netherlands.

BACKGROUND AND METHODS: The characteristics and frequency of clinical problems with the performance of euthanasia and physician-assisted suicide are uncertain. We analyzed data from two studies of euthanasia and physician-assisted suicide in The Netherlands (one conducted in 1990 and 1991 and the other in 1995 and 1996), with a total of 649 cases. We categorized clinical problems as technical problems, such as difficulty inserting an intravenous line; complications, such as myoclonus or vomiting; or problems with completion, such as a longer-than-expected interval between the administration of medications and death. RESULTS: In 114 cases, the physician's intention was to provide assistance with suicide, and in 535, the intention was to perform euthanasia. Problems of any type were more frequent in cases of assisted suicide than in cases of euthanasia. Complications occurred in 7 percent of cases of assisted suicide, and problems with completion (a longer-than-expected time to death, failure to induce coma, or induction of coma followed by awakening of the patient) occurred in 16 percent of the cases; complications and problems with completion occurred in 3 percent and 6 percent of cases of euthanasia, respectively. The physician decided to administer a lethal medication in 21 of the cases of assisted suicide (18 percent), which thus became cases of euthanasia. The reasons for this decision included problems with completion (in 12 cases) and the inability of the patient to take all the medications (in 5). CONCLUSIONS: There may be clinical problems with the performance of euthanasia and physician-assisted suicide. In The Netherlands, physicians who intend to provide assistance with suicide sometimes end up administering a lethal medication themselves because of the patient's inability to take the medication or because of problems with the completion of physician-assisted suicide.

Prevalence and content analysis of guidelines on handling requests for euthanasia or assisted suicide in Dutch nursing homes.

BACKGROUND: The growing number of requests for euthanasia or assisted suicide (EAS) makes it imperative for health care institutions, such as nursing homes, to have written guidelines on how to handle requests for EAS. The objective of this study was to determine the prevalence of EAS guidelines in Dutch nursing homes and to analyze the content. METHODS: Directors of patient care in 324 Dutch nursing homes were asked, by means of a mailed short list of questions, if they had an institutional guideline on EAS and, if so, to provide a copy. Guidelines were analyzed according to a structured list of items based on current jurisprudence, model documents, and opinions of experts. RESULTS: Of the 324 directors, 313 (97%) responded. In 58% of the nursing homes that responded, there existed written guidelines for EAS. Of those guidelines, 74% concerned EAS; in 26%, EAS was integrated in a guideline on terminal care. Of the guidelines, 165 (90%) were based on the policy that EAS is acceptable under specific conditions, and 18 (10%) banned EAS completely. Of the first-mentioned guidelines, 81% described one or more procedures for in-principle objections. In 65% of these guidelines, all official requirements for prudent practice were described. CONCLUSIONS: Despite the rapidly growing number of nursing-home guidelines on EAS and the existence of model documents, there is still considerable variation in the guidelines, and they can be improved in many aspects. A basic prerequisite is that the guidelines include all the official requirements for prudent practice.

A nationwide study of decisions to forego life-prolonging treatment in Dutch medical practice.

BACKGROUND: Decisions to withhold or withdraw life-prolonging treatment in terminally ill patients are common in some areas of medical practice. Information about the frequency and background of these decisions is generally limited to specific clinical settings. This article describes the practice of withholding or withdrawing life-prolonging treatment in the Netherlands. METHODS: Questionnaires were sent to the attending physicians of a stratified sample of 6060 of all 43002 cases of death in the Netherlands from August 1 through November 30, 1995. The questions concerned the treatments foregone, the patient characteristics, and the decision-making process. The response rate was 77%. RESULTS: A nontreatment decision was made in 30% (95% confidence interval, 28%-31%) of all deaths in the Netherlands in 1995; this is an increase compared with 28% (95% confidence interval, 26%-29%) in 1990; in 20% of all deaths, this decision was the most important end-of-life decision. Artificial nutrition or hydration and antibiotics were the treatments most frequently foregone, each accounting for 25% of cases in which a nontreatment decision was made. Nursing-home physicians withheld or withdrew treatment more often than clinical specialists or general practitioners in 52%, 35%, and 17% of all deaths they were involved with, respectively. Of the patients in whom a nontreatment decision was the most important end-of-life decision, 26% were competent; of those, 93% were involved in the decision making. In 17% of patients, the nontreatment decision was made without being discussed with the patient or the patient's relatives and without knowledge of the patient's wishes. Life was shortened by an estimated 24 hours or less in 42% and 1 month or more in 8% of patients. CONCLUSIONS: Decisions to forego life-prolonging treatment are frequently made end-of-life decisions in the Netherlands and may be increasing. Most of these decisions do not involve high-technology treatments, and the consequences, in terms of shortening of life, are relatively small.

Attitudes and practices concerning the end of life: a comparison between physicians from the United States and from The Netherlands.

BACKGROUND: This study compares attitudes and practices concerning the end-of-life decisions between physicians in the United States and in the Netherlands, using the same set of questions. METHODS: A total of 152 physicians from Oregon and 67 from the Netherlands were interviewed using the same questions about (1) their attitudes toward increasing morphine with premature death as a likely consequence, physician-assisted suicide (PAS), and euthanasia; and (2) their involvement in cases of euthanasia, PAS, or the ending of life without an explicit request from the patient. Odds ratios, with 95% confidence intervals, were calculated to investigate relation between attitudes and various characteristics of the respondents. RESULTS: American physicians found euthanasia less often acceptable than the Dutch, but there was similarity in attitudes concerning increasing morphine and PAS. American physicians found increasing morphine and PAS more often acceptable in cases where patients were concerned about becoming a burden to their family. There was a discrepancy between the attitudes and practices of Dutch physicians concerning PAS. The proportions of physicians having practiced euthanasia, PAS, or ending of life without an explicit request from the patient differ more between the countries than do their attitudes, with American physicians having been involved in these practices less often than the Dutch. CONCLUSIONS: In this study of American and Dutch physicians, 2 important differences emerge: different attitudes toward the patient who is concerned over being a burden, and different frequency of euthanasia and PAS in the two countries.

Consultation with another physician on euthanasia and assisted suicide in the Netherlands.

Consultation with another physician is considered to be an important safeguard of the practice of euthanasia and physician-assisted suicide. The objective is to describe the frequency and characteristics of consultation in cases of euthanasia or physician-assisted suicide (EAS) in the Netherlands. Data from two cross-sectional descriptive nationwide surveys, carried out in 1995, were used. Questionnaires were mailed to physicians attending 6060 deaths, identified from death certificates, and a stratified sample of 405 physicians were interviewed. In 1990, a cross-sectional descriptive postal survey of a random sample of 1042 general practitioners took place. Consultation took place in 63% of cases of EAS in the Netherlands, in 99% of the cases reported to the public prosecutor and in approximately 37% of unreported cases. In almost half of the unreported cases the decision had been discussed less formally with at least one colleague. In 1990, 7% of general practitioners met all 8 criteria for good consultation; this increased to 64% in 1995. Of the respondents, 26% had at some time advised against performing euthanasia or assisted suicide when acting as a consultant. This study shows that approximately two thirds of all cases of EAS are safeguarded by consultation. Although in the majority of these cases the consultation is of good quality, there is certainly still room for improvement. The quality of consultation could be improved, for instance, by appointing independent and specifically trained consultants.

Using potentially life-shortening drugs in neonates and infants.

OBJECTIVE: To describe the frequency, background, and impact of decisions to give analgesic or other drugs that may, intentionally or unintentionally, shorten the life-span of severely ill neonates. SETTING: The Netherlands. DESIGN: Retrospective, cross-sectional study. PATIENTS: Questionnaires were mailed in The Netherlands to physicians reporting 338 consecutive deaths of infants under 1 yr of age from August through November 1995. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Questions were asked about medical end-of-life decisions preceding the death of the infant and about the decision-making process. Potentially life-shortening drugs, mostly opioids, were given in 37% of all deaths. The estimated effect in terms of the shortening of life was <1 wk in 72% of all patients in whom the administration of potentially life-shortening drugs had been the most important end-of-life decision. Most decisions to administer such drugs were discussed with parents and colleagues. The decisions were discussed regarding virtually all patients in whom the physician had intended to hasten death; doses of opioids tended to be larger in this group. CONCLUSIONS: The frequency with which drugs that may shorten life are administered before the death of severely ill infants confirms the important role of modern medicine in dying in neonatology. Most physicians caring for neonates feel that palliative medication may be warranted in dying infants, even if it shortens life. A distinction between intentionally ending life and providing adequate terminal care by alleviating pain or other symptoms, which is important in moral and judicial terms, is probably not easily made for some of these patients.

Guidelines for the use of do-not-resuscitate orders in Dutch hospitals.

OBJECTIVES: To determine the prevalence and analyze the content of guidelines for the use of do-not-resuscitate (DNR) orders in Dutch hospitals. DESIGN: Cross-sectional descriptive study. MEASUREMENTS AND MAIN RESULTS: A questionnaire was mailed to the directors of patient care at all 143 Dutch hospitals. Directors were asked whether their hospitals had guidelines for the use of DNR orders and to provide copies of the guidelines if they did. The content of the guidelines was analyzed with regard to basic assumptions about nonresuscitation, definitions, persons involved in decision-making, advance directives, starting discussions about nonresuscitation, notation, evaluation, and other aspects. Of the 143 hospital directors surveyed, 95% responded. Sixty percent of the hospitals had guidelines for the use of DNR orders and provided copies. The assumption "always resuscitate, unless" was mentioned in 66% of guidelines. In 93% it was stated that patients should be involved in decision-making about nonfutile resuscitation. In 38% it was stated that in principle, living wills were respected in cases of incompetence. The role of proxies was mainly to discuss decisions (58% of guidelines), not to make them. The most frequently mentioned moment for starting a discussion about nonresuscitation was the onset of clinical deterioration of the patient (41%). CONCLUSIONS: It is promising that 60% of Dutch hospitals have developed guidelines for the use of DNR orders. However, current guidelines can be improved in many respects.

Decisions to treat or not to treat pneumonia in demented psychogeriatric nursing home patients: development of a guideline.

Non-treatment decisions concerning demented patients are complex: in addition to issues concerning the health of patients, ethical and legal issues are involved. This paper describes a method for the development of a guideline that clarifies the steps to be taken in the decision making process whether to forgo curative treatment of pneumonia in psychogeriatric nursing home patients. The method of development consisted of seven steps. Step 1 was a literature study from which ethical, juridical and medical factors concerning the patient's health and prognosis were identified. In step 2, a questionnaire was sent to 26 nursing home physicians to determine the relative importance of these factors in clinical practice. In a meeting of nine experienced physicians (step 3), the factors identified in step 2 were confirmed by most of these professionals. To prevent the final guideline being too directive, a concept guideline that included ethical and legal aspects was designed in the form of a "checklist of considerations" (step 4). Experts in the fields of nursing home medicine, ethics and law reviewed and commented on the concept guideline (step 5). The accordingly adapted "checklist of considerations" was tested in a pilot study (step 6), after which all experts endorsed the checklist (step 7). The resulting "checklist of considerations" structures the decision making process according to three primary domains: medical aspects, patient's autonomy, and patient's best interest (see annex at end of paper).

The role of the medical examiner in the euthanasia notification procedure in The Netherlands.

The objective of the study was to provide an insight into the role of the medical examiner in the euthanasia notification procedure in The Netherlands. At the beginning of 1996 a representative group of 116 medical examiners was interviewed. The study found that there was a considerable variation in the way in which the medical examiners fulfilled their tasks. In all cases, after the physician-assisted death had taken place, the medical examiner investigated whether the attending physician had met the requirements for prudent practice, and in approximately 75% of the cases he reported his findings to the Public Prosecutor. In 78% of cases the attending physician was well known to the medical examiners, who were general practitioners, and in a third of the cases this influenced their assessment. Seventy-six per cent of the medical examiners, 61% of the members of the public prosecution and 47% of the physicians thought that it is the task to the medical examiner to review whether the requirements for prudent practice have been met by the attending physician. In conclusion further specification of the task of the medical examiner would appear to be beneficial to increase uniformity in the procedure. In particular, it should be determined whether it is the medical examiner's responsibility to review whether the requirements for prudent practice have been met. It should also be taken into consideration whether the position of the general practitioner medical examiner is sufficiently independent to make an objective report.

Physical risk factors for neck pain.

To identify physical risk factors for neck pain, a systematic review of the literature was carried out. Based on methodological quality and study design, 4 levels of evidence were defined to establish the strength of evidence for the relationship between risk factors and neck pain. Altogether, 22 cross-sectional studies, 2 prospective cohort studies, and 1 case-referent study were eligible for determining the level of evidence. The results showed some evidence for a positive relationship between neck pain and the duration of sitting and twisting or bending of the trunk. A sensitivity analysis was carried out excluding 3 items of the quality list, the importance of which seemed doubtful. On the basis of this sensitivity analysis, it was concluded that there is some evidence for a positive relationship between neck pain and the following work-related risk factors: neck flexion, arm force, arm posture, duration of sitting, twisting or bending of the trunk, hand-arm vibration, and workplace design.

[Foregoing artificial feeding and hydration for nursing home patients in the last phase of life].

For 3 nursing home patients in bad physical and psychiatric condition and with a poor prognosis, 2 women aged 86 and 84 years and 1 man aged 55 years, it was decided to forgo artificial feeding and hydration, after which they passed away quietly within about a week. It appears that dying in that way does not cause much suffering. Before the decision of forgoing is taken the following factors should be considered: the cause of a diminishing food and fluid intake, the severity and prognosis of underlying diseases and the (supposed) wishes of the patient. Therefore an open communication with relatives and nurses is necessary.
