Patients with eventually fatal chronic illness: their importance within a national research agenda on improving patient safety and reducing medical errors

Adverse events at the end of life of hospital patients with or without a condition relevant for palliative care: a nationwide retrospective record review study in the Netherlands

BACKGROUND

Patient safety is crucial for quality of care. Preventable adverse events (AEs) occur in 1 of 20 patients in the hospital, but it is unknown whether this is different for patients with a condition relevant for palliative care. The majority of the limited available research on this topic is only focused on patients already receiving palliative care, and do not make comparisons with other patients at the end-of-life. We identified and compared the prevalence, preventability, nature and causes of AEs in patients with and without a condition relevant for palliative care.

METHODS

A nationwide retrospective record review study was performed in 20 Dutch hospitals. A total of 2,998 records of patients who died in hospital in 2019 was included. Records were reviewed for AEs. We identified two subgroups: patients with (n = 2,370) or without (n = 248) a condition relevant for palliative care through the selection method of Etkind (2017). Descriptive analyses were performed to calculate prevalence, nature, causes and prevention strategies. T-tests were performed to calculate differences between subgroups.

RESULTS

We found no significant differences between subgroups regarding AE prevalence, this was 15.3% in patients with a condition relevant for palliative care, versus 12.0% in patients without a condition relevant for palliative care (p = 0.148). Potentially preventable AE prevalence was 4.3% versus 4.4% (p = 0.975). Potentially preventable death prevalence in both groups was 3.2% (p = 0.938). There were differences in the nature of AEs: in patients with a condition relevant for palliative care this was mostly related to medication (33.1%), and in patients without a condition relevant for palliative care to surgery (50.8%). In both subgroups in the majority of AEs a patient related cause was identified. For the potentially preventable AEs in both subgroups the two most important prevention strategies as suggested by the medical reviewers were reflection and evaluation and quality assurance.

DISCUSSION

Patient safety risks appeared to be equally prevalent in both subgroups. The nature of AEs does differ between subgroups: medication- versus surgery-related, indicating that tailored safety measures are needed. Recommendations for practice are to focus on reflecting on AEs, complemented with case evaluations.

Prevalence of Triggers and Patient Harm Identified by Global Trigger Tool in Specialized Palliative Care

Background: Global trigger tool (GTT) was developed for identification of patient harm. In palliative patients deterioration can be expected, and there are no data on whether cases classified as "patient harm" actually represents a potential for improved patient safety. Objectives: The primary aim was to test the performance and suitability of GTT in palliative care patients. The secondary aim was to pilot triggers for substandard palliative care. Design and Measurements: GTT was applied in 113 consecutive patients at a palliative ward at a Norwegian university hospital. Cases of patient harm were further evaluated to decide if the case was (a) a natural part of the disease trajectory or (b) a foreseeable consequence of treatment decisions. Potential triggers for substandard palliative care were tested. Results: Two hundred twelve triggers (1.9 per hospitalization) and 26 cases of patient harm were identified. The positive predictive value (PPV) for identifying patient harm was 0.12. The most prevalent harm was pressure ulcers (8.8%). Of the 26 cases of patient harm, 6 cases were a natural part of the disease trajectory and 10 consequences of treatment decisions. In 21 (18%) patients triggers being piloted for substandard palliative care were present, identifying 9 cases of substandard palliative care. The highest PPV (0.67) was observed for "Cessation of antibiotics less than 5 days before death." Conclusions: With the exception of pressure ulcers, GTT triggers were infrequent or had a very poor PPV for patient harm. Triggers related to overtreatment might be suitable for identifying substandard palliative care.

How Safe Do Dying People Feel at Home? Patients' Perception of Safety While Receiving Specialist Community Palliative Care

BACKGROUND

There is a research gap regarding safety concerns of patients at the end of life. The aim of this study was, therefore, to explore whether patients under specialist community palliative care feel safe at home and which factors affect the perceived safety. Furthermore, we investigated if perception of safety is associated with different aspects of subsequent care.

METHODS

Using a standardized questionnaire, a cross-sectional survey was conducted among 100 specialist community palliative care patients. Logistic regression was used to examine the strength of the association between clinical and socio-demographic variables and the perception of safety. After a 6-month follow-up period, we analyzed differences in various care-related outcomes between patients with unaffected and impaired perceptions of safety.

RESULTS

In our study, one in five patients receiving specialist community palliative care expressed safety concerns. Subdomains of safety that were reported most frequently were physical disability (60%), physical symptoms (30%), psychological symptoms (26%), and side effects/complications of drug therapy (19%). Of the participants surveyed after the initial COVID-19 lockdown, 35.1% reported that they felt their safety had been adversely affected by the pandemic. Compromised safety perception was associated with higher levels of palliative care-related problems, and proximity to death.

CONCLUSIONS

Our study uncovered relevant safety concerns of palliative care patients receiving specialist community palliative care. The insights gained into patient-reported problems may help healthcare professionals to identify situations where patients feel unsafe. Further research should address primary and secondary prevention measures to improve the quality of end-of-life care in the home environment.

Patient Safety in Palliative and End-of-Life Care: A Text Mining Approach and Systematic Review of Definitions

BACKGROUND

Patient safety has gained an increasing profile as a crucial element of healthcare. However, not only is there little evidence on the relevance of the term in the palliative and end-of-life care literature but also a lack of a precise and uniform definition.

METHOD

With a text mining approach occurrence of the term patient safety was determined in all available abstracts of 10 palliative and end-of-life care journals. Furthermore, 4 electronic databases (MEDLINE, EMBASE, CINAHL and PSYCINFO) were searched supplemented by hand-searching of relevant literature to identify and conceptualize published definitions of patient safety in the palliative and end-of-life care context. Publications were independently assessed against inclusion criteria by 2 authors.

RESULTS

Our search of 14,351 abstracts yielded 41 hits for "patient safety" ranking 2,345 in the list of most commonly encountered tokens. We identified 11 definitions of patient safety stemming from 11 publications. Definitions differed with regard to the concept of process or outcome. They also allowed distinctive perspectives on the extent to which patient care influences patient safety. Lastly, exact wording led to discrepancies in the understanding of unsafe care and generalizability of definitions.

CONCLUSION

Our results indicate that patient safety has gradually gained importance in palliative and end-of-life care. However, as key elements of definientia varied considerably no consensus definition could be identified. Nevertheless, a universal definition would help to facilitate communication and exchange of information among individuals and organizations involved in palliative and end-of-life care.

Clinicians' perceptions of opioid error-contributing factors in inpatient palliative care services: A qualitative study

BACKGROUND

Opioid errors are a leading cause of patient harm and adversely impact palliative care inpatients' pain and symptom management. Yet, the factors contributing to opioid errors in palliative care are poorly understood. Identifying and better understanding the individual and system factors contributing to these errors is required to inform targeted strategies.

OBJECTIVES

To explore palliative care clinicians' perceptions of the factors contributing to opioid errors in Australian inpatient palliative care services.

DESIGN

A qualitative study using focus groups or semi-structured interviews.

SETTINGS

Three specialist palliative care inpatient services in New South Wales, Australia.

PARTICIPANTS

Inpatient palliative care clinicians who are involved with, and/or have oversight of, the services' opioid delivery or quality and safety processes.

METHODS

Deductive thematic content analysis of the qualitative data. The Yorkshire Contributory Factors Framework was applied to identify error-contributing factors.

FINDINGS

A total of 58 clinicians participated in eight focus groups and 20 semi-structured interviews. Nine key error contributory factor domains were identified, including: active failures; task characteristics of opioid preparation; clinician inexperience; sub-optimal skill mix; gaps in support from central functions; the drug preparation environment; and sub-optimal clinical communication.

CONCLUSION

This study identified multiple system-level factors contributing to opioid errors in inpatient palliative care services. Any quality and safety initiatives targeting safe opioid delivery in specialist palliative care services needs to consider the full range of contributing factors, from individual to systems/latent factors, which promote error-causing conditions.

Patient safety in palliative care: A mixed-methods study of reports to a national database of serious incidents

BACKGROUND

Patients receiving palliative care are vulnerable to patient safety incidents but little is known about the extent of harm caused or the origins of unsafe care in this population.

AIM

To quantify and qualitatively analyse serious incident reports in order to understand the causes and impact of unsafe care in a population receiving palliative care.

DESIGN

A mixed-methods approach was used. Following quantification of type of incidents and their location, a qualitative analysis using a modified framework method was used to interpret themes in reports to examine the underlying causes and the nature of resultant harms.

SETTING AND PARTICIPANTS

Reports to a national database of 'serious incidents requiring investigation' involving patients receiving palliative care in the National Health Service (NHS) in England during the 12-year period, April 2002 to March 2014.

RESULTS

A total of 475 reports were identified: 266 related to pressure ulcers, 91 to medication errors, 46 to falls, 21 to healthcare-associated infections (HCAIs), 18 were other instances of disturbed dying, 14 were allegations against health professions, 8 transfer incidents, 6 suicides and 5 other concerns. The frequency of report types differed according to the care setting. Underlying causes included lack of palliative care experience, under-resourcing and poor service coordination. Resultant harms included worsened symptoms, disrupted dying, serious injury and hastened death.

CONCLUSION

Unsafe care presents a risk of significant harm to patients receiving palliative care. Improvements in the coordination of care delivery alongside wider availability of specialist palliative care support may reduce this risk.

Determining nurses' perceptions of patient safety culture in palliative care centres

Background: Palliative care patients often do not have decision-making capacity at the end of life so this patient group is vulnerable to violations of patient safety.Aim: To determine the attitudes of nurses in palliative care centres in Turkey towards the patient safety culture and to identify factors affecting these.Method: A descriptive, cross-sectional design using self-report questionnaires was used.Results: The mean Patient Safety Culture Scale points of the whole group were 2.91 ± 0.44. In the sub-dimensions of the scale, the highest points were determined in Employee Training (2.99 ± 0.51) and the lowest in Unexpected Events and Error Reporting (2.81 ± 0.54).Conclusions: Patient safety culture is related to nurses' working conditions and the attitude of management towards errors, etc. The results of this study will provide a contribution to the development of healthcare and healthcare training policies for critical units vulnerable to patient safety violations.

Opioid errors in inpatient palliative care services: a retrospective review

Opioids are a high-risk medicine frequently used to manage palliative patients’ cancer-related pain and other symptoms. Despite the high volume of opioid use in inpatient palliative care services, and the potential for patient harm, few studies have focused on opioid errors in this population.

Objectives

To (i) identify the number of opioid errors reported by inpatient palliative care services, (ii) identify reported opioid error characteristics and (iii) determine the impact of opioid errors on palliative patient outcomes.

Methods

A 24-month retrospective review of opioid errors reported in three inpatient palliative care services in one Australian state.

Results

Of the 55 opioid errors identified, 84% reached the patient. Most errors involved morphine (35%) or hydromorphone (29%). Opioid administration errors accounted for 76% of reported opioid errors, largely due to omitted dose (33%) or wrong dose (24%) errors. Patients were more likely to receive a lower dose of opioid than ordered as a direct result of an opioid error (57%), with errors adversely impacting pain and/or symptom management in 42% of patients. Half (53%) of the affected patients required additional treatment and/or care as a direct consequence of the opioid error.

Conclusion

This retrospective review has provided valuable insights into the patterns and impact of opioid errors in inpatient palliative care services. Iatrogenic harm related to opioid underdosing errors contributed to palliative patients’ unrelieved pain. Better understanding the factors that contribute to opioid errors and the role of safety culture in the palliative care service context warrants further investigation.

Quantifying the burden of opioid medication errors in adult oncology and palliative care settings: A systematic review

BACKGROUND

Opioids are the primary pharmacological treatment for cancer pain and, in the palliative care setting, are routinely used to manage symptoms at the end of life. Opioids are one of the most frequently reported drug classes in medication errors causing patient harm. Despite their widespread use, little is known about the incidence and impact of opioid medication errors in oncology and palliative care settings.

AIM

To determine the incidence, types and impact of reported opioid medication errors in adult oncology and palliative care patient settings.

DESIGN

A systematic review.

DATA SOURCES

Five electronic databases and the grey literature were searched from 1980 to August 2014. Empirical studies published in English, reporting data on opioid medication error incidence, types or patient impact, within adult oncology and/or palliative care services, were included. Popay's narrative synthesis approach was used to analyse data.

RESULTS

Five empirical studies were included in this review. Opioid error incidence rate was difficult to ascertain as each study focussed on a single narrow area of error. The predominant error type related to deviation from opioid prescribing guidelines, such as incorrect dosing intervals. None of the included studies reported the degree of patient harm resulting from opioid errors.

CONCLUSION

This review has highlighted the paucity of the literature examining opioid error incidence, types and patient impact in adult oncology and palliative care settings. Defining, identifying and quantifying error reporting practices for these populations should be an essential component of future oncology and palliative care quality and safety initiatives.

Improving the quality of care delivered to people imminently dying in hospital by implementing a care bundle: an observational before and after feasibility study

Introduction

Most Australians die predictably in acute hospital settings. Despite this, hospitals remain ill-equipped to care for dying patients with hospital deaths not uncommonly perceived as distressing by both patients and their families. A care bundle for the dying was developed with this aiming to report the feasibility of implementing this quality improvement strategy.

Methods

A before and after observational approach was used to compare whether there were changes in care delivery to imminently dying patients in two medical wards. Data were extracted retrospectively from their inpatient files. The main outcome of this work was the percentage compliance with the bundle elements and proportional change from baseline where comparative care processes had previously been in place.

Results

Over 6 months, 90 deaths occurred with the bundle in place for 74.5% (n = 70) with significant increases in regular symptom monitoring and monitoring of family distress seen ( p < 0.001, respectively). There was compliance with prescribing guideline for pain in 59.2% (29/49) charts and breathlessness in 53.1% (26/49). In the absence of previous prescribing guidelines it was not possible to comment on the significance of this latter observation.

Discussion

This work highlights that it is feasible to implement and assess a pilot project aimed at improving the quality of care delivered to people dying in acute hospitals. This preliminary work suggests that it is possible to integrate evidence-based care processes into the care of the dying by adopting a care paradigm more typically reserved for critical care. However, more work is required to confirm this in larger studies.

Medical errors and patient safety in palliative care: a review of current literature

BACKGROUND

Recently, the discussion about medical errors and patient safety has gained scientific as well as public attention. Errors in medicine have been proven to be frequent and to carry enormous financial costs and moral consequences. We aimed to review the research on medical errors in palliative care and to screen relevant literature to appreciate the relevance of safety studies to the field.

METHODS

We performed a literature search using the database PubMed that cross-matched terms for palliative care with the words "errors" and "patient safety." Publications were classified according to type of study and kind of error, and empiric research results were extracted and critically assessed.

RESULTS

We found 44 articles concerning medical errors in palliative care, most of which were case studies. Of these 44 articles, 16 deal with palliative care errors as a key issue, referring mostly to symptom control (n = 13). Other examples are errors in communication, prognostication, and advance care planning. There are very few empirical studies, which are mostly retrospective observational studies.

DISCUSSION

Although patients in palliative care are more vulnerable to errors and their consequences, there is little theoretical or empirical research on the subject. We propose a specific definition for errors in palliative care and analyze the challenges of delineating, identifying and preventing errors in such key areas as prognostication, advance care planning and end-of-life decision-making.

Soliciting an herbal medicine and supplement use history at hospice admission

BACKGROUND

Reconciling medication use and performing drug utilization review on admission of a patient into hospice care are essential in order to safely prescribe medications and to prevent possible adverse drug events and drug-drug interactions. As part of this process, fully assessing herbal medicine and supplement use in hospice patients is crucial, as patients in hospice may be likely to use these medications and may be more vulnerable to their potential adverse effects.

OBJECTIVE

Our purpose was to identify herbals, vitamins, and supplements that should be routinely assessed on every hospice admission because of their higher likelihood of use or higher risk of adverse effects or drug interactions.

METHODS

Experts in the fields of palliative medicine, pharmacy, and alternative medicine were asked to complete a Web-based survey on 37 herbals, vitamins, supplements, and natural products, rating likelihood of use, potential for harm, and recommendation to include it on the final list on a scale of 1 to 5 (least to most likely to agree).

RESULTS

Twenty experts participated in the survey. Using a cutoff of 3.75 for inclusion of a medication on the final list, 12 herbal medicines were identified that should be routinely and specifically assessed on hospice admission.

CONCLUSIONS

Although assessing all herbal medicine use is ideal, thorough detection of herbals may be challenging. The list of herbals and supplements identified by this survey could be a useful tool for medication reconciliation in hospice and could aid in identifying potentially harmful medication use at the end of life.

Utilization of health-care services at the end-of-life

End-of-life care poses a growing clinical and policy concern since most people who are dying utilize health-care services during this period of life. Hence, end-of-life care is a common and integral part of the care provided by health-care systems. There is a growing call for the implementation of a palliative approach as an integral part of all end-of-life care. The purpose of this study was thus to provide policy-makers, health-care providers and professional caregivers with increased knowledge about mainstream patterns of health-care utilization during end-of-life. The patterns of use of health-care services in a Swedish population who accessed the health-care system during their last 3 months of life were in this study examined through a retrospective examinations of medical and nursing records (n=229). We found high prevalences of use of both hospital care, primary care and care provided in people's homes and nearly three quarters of the persons included in the study used between two and three health-care services. However, the probability of using different health-care services was found to be strongly depending on demographic, social, functional and disease related characteristics. The study reveals a considerable use of different health-care services during end-of-life. It is hence essential to, on one hand delineate how such health-care services best can support people at the end-of-life, and on the other hand develop policies which facilitate the process of dying, both in hospitals as well as in peoples' homes. Implications for policy are discussed.

Changes in the use of do-not-resuscitate orders after implementation of the Patient Self-Determination Act

OBJECTIVE

To determine changes in the use of do-not-resuscitate (DNR) orders and mortality rates following a DNR order after the Patient Self-determination Act (PSDA) was implemented in December 1991.

DESIGN

Time-series.

SETTING

Twenty-nine hospitals in Northeast Ohio.

PATIENTS/PARTICIPANTS

Medicare patients (N = 91,539) hospitalized with myocardial infarction, heart failure, gastrointestinal hemorrhage, chronic obstructive pulmonary disease, pneumonia, or stroke.

MEASUREMENTS AND MAIN RESULTS

The use of "early" (first 2 hospital days) and "late" DNR orders was determined from chart abstractions. Deaths within 30 days after a DNR order were identified from Medicare Provider Analysis and Review files. Risk-adjusted rates of early DNR orders increased by 34% to 66% between 1991 and 1992 for 4 of the 6 conditions and then remained flat or declined slightly between 1992 and 1997. Use of late DNR orders declined by 29% to 53% for 4 of the 6 conditions between 1991 and 1997. Risk-adjusted mortality during the 30 days after a DNR order was written did not change between 1991 and 1997 for 5 conditions, but risk-adjusted mortality increased by 21% and 25% for stroke patients with early DNR and late DNR orders, respectively.

CONCLUSIONS

Overall use of DNR orders changed relatively little after passage of the PSDA, because the increase in the use of early DNR orders between 1991 and 1992 was counteracted by decreasing use of late DNR orders. Risk-adjusted mortality rates after a DNR order generally remained stable, suggesting that there were no dramatic changes in quality of care or aggressiveness of care for patients with DNR orders. However, the increasing mortality for stroke patients warrants further examination.

The 107th Congress' legislative proposals concerning end-of-life care

PURPOSE

The current health care system cannot reliably meet the needs of patients with eventually fatal chronic illnesses near the end-of-life. Enduring change requires improved public policy, in part because most paid care for serious illness at the end of life now relies on federal programs. This project reviews the legislation proposed in the 107th Congress (2001-2002) related to improving end-of-life care.

METHODS

We searched THOMAS, the search engine of the Library of Congress, to identify all bills relating to end-of-life care introduced in either house of the U.S. Congress during the 2001/2002 legislative period. Using explicit criteria intended to find any that received serious attention and incorporating recommendations of political consultants, the initial 563 bills narrowed to 22. We summarize their status as of October 24, 2002.

RESULTS

The 22 bills identified dealt with the following topics: demonstration or research projects (9), palliative care or hospice (8), caregivers (7), chronic illness generally (5), care coordination (2), and long-term health care (3). Dementia, graduate medical education, nursing, and pain appeared in 1 bill each. Congress enacted only 1 of the bills. Only 7 bills had more than 10% of either house as sponsors.

CONCLUSIONS

While Medicare reform and health care costs are prominent topics among policymakers, Congress is considering essentially no fundamental changes that would remedy the problems associated with health care for the elderly who are seriously ill near the end-of-life. The mismatch between the urgency of policy reform and the lack of vehicles and momentum to achieve reform calls for consensus and leadership from those concerned with hospice and palliative care.

Medication misadventure in cancer care

OBJECTIVES

To describe the nature and scope of the problem of medication errors in health care, with specific implications for error reduction and prevention.

DATA SOURCES

Articles and research studies.

CONCLUSIONS

Because of the complexity of chemotherapeutic regimens, requirements for supportive care drugs, and the physiologic vulnerability of patients due to their malignancies and intensive therapies, patients with cancer should be the focus of interdisciplinary medication error prevention programs.

IMPLICATIONS FOR NURSING PRACTICE

Nurses play a critical role in patient safety and the implementation of preventive and risk-reducing interventions to improve the drug delivery process.
