Measuring patient safety culture: an assessment of the clustering of responses at unit level and hospital level

Objectives: To test the claim that the Hospital Survey on Patient Safety Culture (HSOPS) measures patient safety culture instead of mere individual attitudes and to determine the most appropriate level (individual, unit or hospital level) for interventions aimed at improving the culture of patient safety. Methods: National patient safety culture data were used from 1889 hospital staff working at 87 units in 19 hospitals across The Netherlands. The multilevel structure of the variation of responses to the 11 dimensions of the questionnaire was explored by fitting three-level random intercept models: individual, unit and hospital level. Results: The unit level was the dominating level for the clustering of responses to the 11 dimensions. Intraclass correlations (ICC) at unit level ranged from 4.3 to 31.7, representing considerable higher-level variation. For three dimensions of patient safety culture, there was significant clustering of responses at hospital level as well: (1) Feedback about and learning from error, (2) Teamwork across hospital units and (3) Non-punitive response to error. Conclusions: At a conceptual level, the detection of clustering of responses within units and hospitals confirms the claim that the HSOPS measures group culture and not just individual attitudes. In addition, the results have implications for interventions on patient safety culture. Improvement efforts should be directed at their most relevant organisational level. In general, improvement efforts on patient safety culture should be addressed at the unit level, rather than the individual or hospital level.

Physician-Assisted Death in Psychiatric Practice in the Netherlands

BACKGROUND In 1994 the Dutch Supreme Court ruled that in exceptional instances, physician-assisted suicide might be justifiable for patients with unbearable mental suffering but no physical illness. We studied physician-assisted suicide and euthanasia in psychiatric practice in the Netherlands. METHODS In 1996, we sent questionnaires to 673 Dutch psychiatrists - about half of all such specialists in the country - and received 552 responses from the 667 who met the study criteria (response rate, 83 percent). We estimated the annual frequencies of requests for physician-assisted suicide by psychiatrists and actual instances of assistance. RESULTS Of the respondents, 205 (37 percent) had at least once received an explicit, persistent request for physician-assisted suicide and 12 had complied. We estimate there are 320 requests a year in psychiatric practice and 2 to 5 assisted suicides. Excluding those who had ever assisted, 345 of the respondents (64 percent) thought physician-assisted suicide because of a mental disorder could be acceptable, including 241 who said they could conceive of instances in which they themselves would be willing to assist. The most frequent reasons for refusing were the belief that the patient had a treatable mental disorder, opposition to assisted suicide in principle, and doubt that the suffering was unbearable or hopeless. Most, but not all, patients who had been assisted by their psychiatrists in suicide had both a mental disorder and a serious physical illness, often in a terminal phase. Thirty percent of the respondents had been consulted at least once by a physician in another specialty about a patients request for assisted death. The annual number of such consultations was estimated at 310, about 3 percent of the estimated 9700 requests for euthanasia or physician-assisted suicide in medical practice. CONCLUSIONS Explicit requests for physician-assisted suicide are not uncommon in psychiatric practice in the Netherlands, but these requests are rarely granted. Psychiatric consultation for medical patients who request physician-assisted death is relatively rare.

The Role of Parents in End-of-Life Decisions in Neonatology: Physicians' Views and Practices

Objective. End-of-life decisions for newborn infants are usually made with the consent of parents as well as physicians, but may occasionally involve disagreement about which decision is in the best interest of the child. Our study was aimed at providing an empirical background for the ethical discussion on the parents versus the physicians role in decision-making. Methods. We conducted face-to-face interviews with a stratified sample of pediatricians. The response rate was 99%. The most recent decisions in newborn infants to hasten death or not prolong life and the most recent cases in which such decisions were not made because either the parents or the physician objected were comprehensively discussed. Results. Decisions to hasten death or not prolong life were usually made after discussing it with parents and did not occur while parents were known to disagree. Situations in which an end-of-life decision was not made because parents did not consent predominantly involved infants with complications of prematurity (24%) or perinatal asphyxia (40%), whereas situations in which parents requested an end-of-life decision that was not acceded to by the pediatrician involved Down syndrome as the main diagnosis in 43% and as a concurrent diagnosis in 21%. Pediatricians afterwards often expressed feelings of discontent about situations in which there had been disagreement with parents. Conclusions. The opinion of parents about which medical decision is in the best interest of their child is for pediatricians only decisive in case it invokes the continuation of treatment. The principle of preserving life is abandoned only when the physician feels sufficiently sure that the parents agree that such a course of action is in the best interest of the child.

Quality of patient record keeping: an indicator of the quality of care?

Background Patient record review of hospitalised patients is by far the most applied method to assess adverse events (AEs) in hospitals. The diligence with which information is recorded may influence the visibility of AEs. On the other hand, poor quality of the information in patient records may be a cause or a consequence of poor quality of care and may thus be associated with higher rates of AEs. The objective of this study was to assess the relation between the quality of patient records and the occurrence of AEs. Methods In this study, 7926 hospital admissions of 21 Dutch hospitals were analysed with a structured record review method. The occurrence of AEs, the presence of patient information and the quality of the present information (completeness, readability and adequacy) were assessed. Their association was analysed using multilevel logistic regression analyses. Results The absence of record components was associated with lower rates of AEs, suggesting that missing record components lead to an underassessment of AEs in record-review studies. In contrast, poor quality of the information present in patient records was associated with higher rates of AEs, implying that the quality of the present patient information is a predictor of the quality of care. Conclusions Evidence-based standards and a (electronic) format for record keeping are necessary for standardisation of recording patient information. This will improve the completeness, readability, accessibility, accuracy and exchange of patient information between healthcare providers and institutions. Better registration of patient information will benefit the quality of the healthcare process and will reduce the risk of AEs.

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.

Exploring the causes of adverse events in hospitals and potential prevention strategies

Objectives To examine the causes of adverse events (AEs) and potential prevention strategies to minimise the occurrence of AEs in hospitalised patients. Methods For the 744 AEs identified in the patient record review study in 21 Dutch hospitals, trained reviewers were asked to select all causal factors that contributed to the AE. The results were analysed together with data on preventability and consequences of AEs. In addition, the reviewers selected one or more prevention strategies for each preventable AE. The recommended prevention strategies were analysed together with four general causal categories: technical, human, organisational and patient-related factors. Results Human causes were predominantly involved in the causation of AEs (in 61% of the AEs), 61% of those being preventable and 13% leading to permanent disability. In 39% of the AEs, patient-related factors were involved, in 14% organisational factors and in 4% technical factors. Organisational causes contributed relatively often to preventable AEs (93%) and AEs resulting in permanent disability (20%). Recommended strategies to prevent AEs were quality assurance/peer review, evaluation of safety behaviour, training and procedures. For the AEs with human and patient-related causes, reviewers predominantly recommended quality assurance/peer review. AEs caused by organisational factors were considered preventable by improving procedures. Discussion Healthcare interventions directed at human causes are recommended because these play a large role in AE causation. In addition, it seems worthwhile to direct interventions on organisational causes because the AEs they cause are nearly always believed to be preventable. Organisational factors are thus relatively easy to tackle. Future research designs should allow researchers to interview healthcare providers that were involved in the event, as an additional source of information on contributing factors.

Trends and determinants of end-of-life practices in ALS in the Netherlands

Background: In the Netherlands, the proportion of patients with amyotrophic lateral sclerosis (ALS) who choose the option of euthanasia or physician-assisted suicide (PAS) is relatively high (20%). The objective of this study was to determine which factors influence end-of-life practices in ALS and whether rates are changing over time. Methods: In a cohort survey, 204 physicians and 198 informal caregivers (response rates 75% and 80%) of patients with ALS who died between 2000 and 2005 filled out questionnaires of the end-of-life circumstances of the patient. Results were compared with those of a similar study performed during the period 1994–1998. Results: In 2000–2005, 16.8% of the patients decided on euthanasia or PAS compared to 20.2% in 1994–1998. Thirty-one (14.8%) patients died during continuous deep sedation (CDS) in 2000–2005. Euthanasia or PAS, but not CDS, were significantly associated with religion not being important to the patient, being more educated, and dying at home. Euthanasia or PAS were not associated with quality of care items or symptoms of depression. Loss of function was similar in both groups. Informal caregivers of patients who died after euthanasia or PAS more frequently reported fear of choking (p = 0.003), no chance of improvement (p = 0.001), loss of dignity (p = 0.02), being dependent on others (p = 0.002), and fatigue (p = 0.018) as reasons for shortening life. Hopelessness was associated with euthanasia or PAS, as with CDS. Conclusion: The frequency of euthanasia or physician-assisted suicide (PAS) in amyotrophic lateral sclerosis (ALS) appeared stable over time and 1 in 7 patients died during CDS. CDS is relatively common in ALS, but appears to have other determinants than euthanasia or PAS. Subjective factors may be important in explaining euthanasia or PAS in ALS.

Dealing with requests for euthanasia: a qualitative study investigating the experience of general practitioners

Background: Caring for terminally ill patients is a meaningful task, however the patient’s suffering can be a considerable burden and cause of frustration. Objectives: The aim of this study is to describe the experiences of general practitioners (GPs) in The Netherlands in dealing with a request for euthanasia from a terminally ill patient. Methods: The data, collected through in-depth interviews, were analysed according to the constant comparative method. Results: Having to face a request for euthanasia when attempting to relieve a patient’s suffering was described as a very demanding experience that GPs generally would like to avoid. Nearly half of the GPs (14/30) strive to avoid euthanasia or physician assisted suicide because it was against their own personal values or because it was emotional burdening to be confronted with this issue. They explained that by being directed on promoting a peaceful dying process, or the quality of end-of-life of a patient by caring and supporting the patient and the relatives it was mainly possible to shorten patient’s suffering without “intentionally hastening a patient’s death on his request”. The other GPs (16/30) explained that as sometimes the suffering of a patient could not be lessened they were open to consider a patient’s request for euthanasia or physician assisted suicide. They underlined the importance of a careful decision-making process, based on finding a balance between the necessity to shorten the patient’s suffering through euthanasia and their personal values. Conclusion: Dealing with requests for euthanasia is very challenging for GPs, although they feel committed to alleviate a patient’s suffering and to promote a peaceful death.

Possibilities and barriers in the implementation of a preconceptional screening programme for cystic fibrosis carriers: a focus group study

OBJECTIVE This qualitative study aimed to explore possibilities and barriers in the implementation of a nationwide preconceptional cystic fibrosis (CF) carrier screening programme. METHODS Sessions were held with two focus groups of CF patients and CF relatives, one focus group of people from the target population (couples planning a pregnancy), and two focus groups of potential providers (general practitioners (GPs) and municipal health service workers). RESULTS Important barriers in the implementation of a preconceptional CF carrier screening programme included the problem of reaching the target population, the heavy workload of GPs, the limited public knowledge about CF in general, and the absence of a preconceptional consultation setting. In general, there was a positive attitude among the participants towards CF carrier screening. CONCLUSION This study revealed some important barriers in the implementation of CF carrier screening programmes. More research is needed to specify and quantify the importance of the various barriers. Eventually, different intervention strategies should be included in an implementation plan to overcome the most important barriers in the organization and execution of screening.
