Survey of Australian and Canadian Community Pharmacists' Experiences With Patients at Risk of Suicide

OBJECTIVE

The study's objective was to examine Canadian and Australian community pharmacists' experiences with people at risk of suicide.

METHODS

A survey was developed and administered online. Countries were compared by Fisher's exact and t tests. Multivariable logistic-regression analysis was used to identify variables associated with preparedness to help someone in a suicidal crisis.

RESULTS

The survey was completed by 235 Canadian and 161 Australian pharmacists. Most (85%) interacted with someone at risk of suicide at least once, and 66% experienced voluntary patient disclosure of suicidal thoughts. More Australians than Canadians had mental health crisis training (p<0.001). Preparedness to help in a suicidal crisis was negatively associated with being Canadian, having a patient who died by suicide, lacking training and confidence, and permissive attitudes toward suicide.

CONCLUSIONS

Several perceived barriers impede pharmacists' abilities to help patients who voluntarily disclose suicidal thoughts. Gatekeeper and related suicide prevention strategy training for community pharmacists is warranted.

Evaluating a Palliative Care Program: Methodology and limitations

The article describes an evaluation of a palliative care service in a regional and tertiary care facility. The service components are described. The four outcomes chosen for evaluation were: (a) symptom relief; (b) satisfaction with care for patients/families; (c) utilization of community resources; (d) good nursing morale and low staff stress. Quality of life was measured using a symptom distress scale; satisfaction using an adapted Kristjanson FAMCARE scale; community resources with opinion and satisfaction surveys; and staff morale and stress with the Maslach Burnout Inventory and Latack's Coping Questionnaire. Results showed that overall symptom distress was reduced. Patients/families were generally satisfied, with some areas needing attention. Physicians were generally satisfied and believed patients/families benefited from the psychosocial support, respite, and education/information. Nurses felt they had the time, energy, resources and support to give quality care.

Hypertension and type 2 diabetes: what family physicians can do to improve control of blood pressure--an observational study

BACKGROUND

The prevalence of type 2 diabetes is rising, and most of these patients also have hypertension, substantially increasing the risk of cardiovascular morbidity and mortality. The majority of these patients do not reach target blood pressure levels for a wide variety of reasons. When a literature review provided no clear focus for action when patients are not at target, we initiated a study to identify characteristics of patients and providers associated with achieving target BP levels in community-based practice.

METHODS

We conducted a practice-based, cross-sectional observational and mailed survey study. The setting was the practices of 27 family physicians and nurse practitioners in 3 eastern provinces in Canada. The participants were all patients with type 2 diabetes who could understand English, were able to give consent, and would be available for follow-up for more than one year. Data were collected from each patient's medical record and from each patient and physician/nurse practitioner by mailed survey. Our main outcome measures were overall blood pressure at target (< 130/80), systolic blood pressure at target, and diastolic blood pressure at target. Analysis included initial descriptive statistics, logistic regression models, and multivariate regression using hierarchical nonlinear modeling (HNLM).

RESULTS

Fifty-four percent were at target for both systolic and diastolic pressures. Sixty-two percent were at systolic target, and 79% were at diastolic target. Patients who reported eating food low in salt had higher odds of reaching target blood pressure. Similarly, patients reporting low adherence to their medication regimen had lower odds of reaching target blood pressure.

CONCLUSIONS

When primary care health professionals are dealing with blood pressures above target in a patient with type 2 diabetes, they should pay particular attention to two factors. They should inquire about dietary salt intake, strongly emphasize the importance of reduction, and refer for detailed counseling if necessary. Similarly, they should inquire about adherence to the medication regimen, and employ a variety of patient-oriented strategies to improve adherence.

Can the introduction of an integrated service model to an existing comprehensive palliative care service impact emergency department visits among enrolled patients?

PURPOSE

Fewer emergency department (ED) visits may be a potential indicator of quality of care during the end of life. Receipt of palliative care, such as that offered by the adult Palliative Care Service (PCS) in Halifax, Nova Scotia, is associated with reduced ED visits. In June 2004, an integrated service model was introduced into the Halifax PCS with the objective of improving outcomes and enhancing care provider coordination and communication. The purpose of this study was to explore temporal trends in ED visits among PCS patients before and after integrated service model implementation.

METHODS

PCS and ED visit data were utilized in this secondary data analysis. Subjects included all adult patients enrolled in the Halifax PCS between January 1, 1999 and December 31, 2005, who had died during this period (N = 3221). Temporal trends in ED utilization were evaluated dichotomously as preintegration or postintegration of the new service model and across 6-month time blocks. Adjustments for patient characteristics were performed using multivariate logistic regression.

RESULTS

Fewer patients (29%) made at least one ED visit postintegration compared to the preintegration time period (36%, p < 0.001). Following adjustments, PCS patients enrolled postintegration were 20% less likely to have made at least one ED visit than those enrolled preintegration (adjusted OR 0.8; 95% confidence interval 0.6-1.0).

CONCLUSION

There is some evidence to suggest the introduction of the integrated service model has resulted in a decline in ED visits among PCS patients. Further research is needed to evaluate whether the observed reduction persists.

Toward population-based indicators of quality end-of-life care: testing stakeholder agreement

BACKGROUND

Quality indicators (QIs) are tools designed to measure and improve quality of care. The objective of this study was to assess stakeholder acceptability of QIs of end-of-life (EOL) care that potentially were measurable from population-based administrative health databases.

METHODS

After a literature review, the authors identified 19 candidate QIs that potentially were measurable through administrative databases. A modified Delphi methodology, consisting of multidisciplinary panels of cancer care health professionals in Nova Scotia and Ontario, was used to assess agreement on acceptable QIs of EOL care (n = 21 professionals; 2 panels per province). Focus group methodology was used to assess acceptability among patients with metastatic breast cancer (n = 16 patients; 2 groups per province) and bereaved family caregivers of women who had died of metastatic breast cancer (n = 8 caregivers; 1 group per province). All sessions were audiotaped, transcribed verbatim, and audited, and thematic analyses were conducted.

RESULTS

Through the Delphi panels, 10 QIs and 2 QI subsections were identified as acceptable indicators of quality EOL care, including those related to pain and symptom management, access to care, palliative care, and emergency room visits. When Delphi panelists did not agree, the principal reasons were patient preferences, variation in local resources, and benchmarking. In the focus groups, patients and family caregivers also highlighted the need to consider preferences and local resources when examining quality EOL care.

CONCLUSIONS

The findings of this study should be considered when developing quality monitoring systems. QIs will be most useful when stakeholders perceive them as measuring quality care.

Palliative care patients in the emergency department

Although end-of-life care is not a primary function of the emergency department (ED), in reality, many access this department in the later stages of illness. In this study, ED use by patients registered with the Capital Health Integrated Palliative Care Service (CHIPCS) is examined and CHIPCS patient characteristics associated with ED use identified. Overall, 27% of patients made at least one ED visit while registered with CHIPCS; 54% of these resulted in a hospital admission. ED visiting was not associated with time of day or day of the week. Multivariate logistic regression results suggest older patients were significantly less likely to make an ED visit. Making an ED visit was associated with hospital death, rural residence (particularly for women), and having a parent or relative other than a spouse or child as the primary caregiver. Further research may suggest strategies to reduce unnecessary ED visits during the end of life.

Quality indicators for cardiovascular primary care

BACKGROUND

The Canadian Cardiovascular Outcomes Research Team was established in 2001 to improve the quality of cardiovascular care for Canadians. Initially, quality indicators (QIs) for hospital-based care for those with acute myocardial infarctions and congestive heart failure were developed and measured. Qualitative research on the acceptability of those indicators concluded that indicators were needed for ambulatory primary care practice, where the bulk of cardiovascular disease care occurs.

OBJECTIVES

To systematically develop QIs for primary care practice for the primary prevention and chronic disease management of ischemic heart disease, hypertension, hyperlipidemia and heart failure.

METHODS

A four-stage modified Delphi approach was used and included a literature review of evidence-based practice guidelines and previously developed QIs; the development and circulation of a survey tool with proposed QIs, asking respondents to rate each indicator for validity, necessity to record and feasibility to collect; an in-person meeting of respondents to resolve rating and content discrepancies, and suggest additional QIs; and recirculation of the survey tool for rating of additional QIs. Participants from across Canada included family physicians, primary care nurses, an emergency room family physician and cardiologists.

RESULTS

31 QIs were agreed on, nine of which were for primary prevention and 22 of which were for chronic disease management.

CONCLUSIONS

A core set of QIs for ambulatory primary care practice has been developed as a tool for practitioners to evaluate the quality of cardiovascular disease care. While the participants rated the indicators as feasible to collect, the next step will be to conduct field validation.

Factors associated with multiple transitions in care during the end of life following enrollment in a comprehensive palliative care program

Background

Patients often experience changes or transitions in where and by whom they are cared for at the end of life. These cause stress for both patients and families. Although not all transitions during the end of life can be avoided, advance identification of those who could potentially experience numerous transitions may allow providers and caregivers to anticipate the problem and consider strategies to minimize their occurrence. This study examines the relationship between patient characteristics and the total number of transitions experienced by the patient from the date of admission to a palliative care program (PCP) to death and during final weeks of life.

Methods

Subjects included all adults registered with the PCP in Halifax, Nova Scotia, Canada between 1998 and 2002 and who had died during that period. Data was extracted from the regional PCP database and linked to census information. Transitions were defined as either: 1) a change in location of where the patient was cared for; or 2) a change in which service (specialist groupings, primary care, etc) provided care. Descriptive statistics were calculated plus rate ratios for the association between patient characteristics and total number of transitions.

Results

In total, 3972 patients made 5903 transitions during the study period. Although 28% experienced no transitions, over 40% experienced one and 6.3% five or more. At least one transition was made by 47% during the last four weeks of life. Adjusted results suggest women, the elderly and more recent death are associated with experiencing fewer transitions. Multiple transitions were associated with a hospital death and a cancer diagnosis. During the last month of life, age was no longer associated with the total number of transitions, cancer patients were found to experience a similar number or fewer transitions than patients with a non-cancer diagnosis and pain and symptom control become a significant factor associated with a greater number of transitions.

Conclusion

Our data suggest there is some variation in the number of transitions associated with the demographics and diagnoses of patients. Associations with gender and age require further exploration as does the contribution of caregiver supports and symptom issues.

Family physician visits and early recognition of melanoma

BACKGROUND

Malignant melanoma is a deadly skin cancer with a rapidly-increasing incidence, mortality and public health burden. Thin melanomas are easily treated with good prognosis, while the thicker lesions have relatively poor survival. To broaden strategies for early recognition of melanoma, we investigated the relationship between primary care service and melanoma thickness at diagnosis.

METHODS

All 714 patients diagnosed with a primary malignant melanoma between January 1995 and December 1999 in Nova Scotia were included in the present study and linked to provincial physician billing databases to reveal the patients' use of family physician services prior to the diagnosis of melanoma. We examined the importance of physician use of services for tumour thickness using logistic regression while adjusting for potential confounders. Tumour thickness was dichotomized to thin and thick using 0.75 mm as a cutoff.

RESULTS

Patients who regularly visited their family physician (2 to 5 times during a two-year interval prior to diagnosis) were 66% (95% CI, 31-84) less likely to be diagnosed with thick melanoma as compared to patients who consulted their family physician less or not at all. Progression to thick tumours could have been reduced by 11.70% (95% CI, -1.33-25.77) if all patients had consulted their family physician at least once a year.

DISCUSSION

Increased awareness of the need for regular medical check-ups could reduce the public health burden of melanoma.

Transitions in care during the end of life: changes experienced following enrolment in a comprehensive palliative care program

Background

Transitions in the location of care and in who provides such care can be extremely stressful for individuals facing death and for those close to them. The objective of this study was to describe the distribution of transitions in care experienced by palliative care patients following admission to a comprehensive palliative care program (PCP). A better understanding of these transitions may aid in reducing unnecessary change, help predict care needs, enhance transitions that improve quality of life, guide health care system communication links and maximize the cost-effective utilization of different care settings and providers.

Methods

Transition and demographic information pertaining to all patients registered in the PCP at the Queen Elizabeth II Health Sciences Centre (QEII), Halifax, Nova Scotia, Canada between January 1, 1998 and December 31, 2002 and who died on or prior to December 31, 2002 was extracted from the PCP database and examined. A transition was defined as either: (1) a change in location of where the patient was cared for by the PCP or, (2) a change in which clinical service provided care. Descriptive analysis provided frequencies and locations of transitions experienced from time of PCP admission to death and during the final two and four weeks of life, an examination of patient movement and a summary of the length of stay spent by patients at each care location.

Results

Over the five year period, 3974 adults admitted to the QEII PCP experienced a total of 5903 transitions (Mean 1.5; standard deviation 1.8; median 1). Patients with no transitions (28%) differed significantly from those who had experienced at least one transition with respect to survival time, age, location of death and diagnosis (p < 0.0001). The majority of patients were admitted to the PCP from various acute care units (66%). Although 54% of all transitions were made to the home, only 60% of these moves included care provided by PCP staff. During the last four weeks of life, 47% of patients experienced at least one transition; 36% during the final two weeks of life. Shorter stays in each location were evident when care was actively provided by the PCP.

Conclusion

A relatively small number of patients under the care of the PCP at the end of life, made several transitions in care setting or service provider. These particular patients need closer scrutiny to understand why such transitions take place so that clinical programs may be designed or modified to minimize the transitions themselves or the impact transitions have on patients and families.

Home visits by family physicians during the end-of-life: Does patient income or residence play a role?

Background

With a growing trend for those with advanced cancer to die at home, there is a corresponding increase in need for primary medical care in that setting. Yet those with lower incomes and in rural regions are often challenged to have their health care needs met. This study examined the association between patient income and residence and the receipt of Family Physician (FP) home visits during the end-of-life among patients with cancer.

Methods

Data Sources/Study Setting. Secondary analysis of linked population-based data. Information pertaining to all patients who died due to lung, colorectal, breast or prostate cancer between 1992 and 1997 (N = 7,212) in the Canadian province of Nova Scotia (NS) was extracted from three administrative health databases and from Statistics Canada census records. Study Design. An ecological measure of income ('neighbourhood' median household income) was developed using census information. Multivariate logistic regression was then used to assess the association of income with the receipt of at least one home visit from a FP among all subjects and by region of residency during the end-of-life. Covariates in the initial multivariate model included patient demographics and alternative health services information such as total days spent as a hospital inpatient. Data Extraction Methods. Encrypted patient health card numbers were used to link all administrative health databases whereas the postal code was the link to Statistics Canada census information.

Results

Over 45% of all subjects received at least one home visit (n = 3265). Compared to those from low income areas, the log odds of receiving at least one home visit was significantly greater among subjects who reside in middle to high income neighbourhoods (for the highest income quintile, adjusted odds ratio [OR] = 1.37, 95% confidence interval [CI] = 1.15, 1.64; for upper-middle income, adjusted OR = 1.19, 95%CI = 1.02, 1.39; for middle income, adjusted OR = 1.33, 95%CI = 1.15, 1.54). This association was found to be primarily associated with residency outside of the largest metropolitan region of the province.

Conclusion

The likelihood of receiving a FP home visit during the end-of-life is associated with neighbourhood income particularly among patients living outside of a major metropolitan region.

Health care restructuring and family physician care for those who died of cancer

BACKGROUND

During the 1990s, health care restructuring in Nova Scotia resulted in downsized hospitals, reduced inpatient length of stay, capped physician incomes and restricted practice locations. Concurrently, the provincial homecare program was redeveloped and out-of-hospital cancer deaths increased from 20% (1992) to 30% (1998). These factors all pointed to a transfer of end-of-life inpatient hospital care to more community-based care. The purpose of this study was to describe the trends in the provision of Family Physician (FP) visits to advanced cancer patients in Nova Scotia (NS) during the years of health care restructuring.

METHODS

Design Secondary multivariate analysis of linked population-based datafiles including the Queen Elizabeth II Health Sciences Centre Oncology Patient Information System (NS Cancer Registry, Vital Statistics), the NS Hospital Admissions/Separations file and the Medical Services Insurance Physician Services database. Setting Nova Scotia, an eastern Canadian province (population: 950,000).

SUBJECTS

All patients who died of lung, colorectal, breast or prostate cancer between April 1992 and March 1998 (N = 7,212). Outcome Measures Inpatient and ambulatory FP visits, ambulatory visits by location (office, home, long-term care facility, emergency department), time of day (regular hours, after hours), total length of inpatient hospital stay and number of hospital admissions during the last six months of life.

RESULTS

In total, 139,641 visits were provided by family physicians: 15% of visits in the office, 10% in the home, 5% in the emergency department (ED), 5% in a long-term-care centre and 64% to hospital inpatients. There was no change in the rate of FP visits received for office, home and long-term care despite the fact that there were 13% fewer hospital admissions, and length of hospital stay declined by 21%. Age-sex adjusted estimates using negative binomial regression indicate a decline in hospital inpatient FP visits over time compared to 1992-93 levels (for 1997-98, adjusted RR = 0.88, 95%CI = 0.81-0.95) and an increase in FP ED visits (for 1997-98, adjusted RR = 1.18, 95%CI = 1.05-1.34).

CONCLUSION

Despite hospital downsizing and fewer deaths occurring in hospitals, FP ambulatory visits (except for ED visits) did not rise correspondingly. Although such restructuring resulted in more people dying out of hospital, it does not appear FPs responded by providing more medical care to them in the community.

Evidence-based cardiovascular care. Family physicians' views of obstacles and opportunities

OBJECTIVE

To explore obstacles to and opportunities for applying specific lifestyle and pharmacologic recommendations on chronic ischemic heart disease.

DESIGN

Qualitative study.

SETTING

Rural, town, and city settings in Nova Scotia.

PARTICIPANTS

Fifty family physicians caring for patients with cardiovascular (CV) disease.

METHOD

Nine focus groups were conducted, audiotaped, and transcribed. Seven recommendations had been selected for discussion based on their relevance to primary care, strength, and class of supporting evidence. Analysis was guided by grounded-theory methodology.

MAIN FINDINGS

"Ischemic events" can be powerful motivators for change, whereas the asymptomatic nature of CV risks and distant outcomes can form obstacles. Trust built through previous experiences and the opportunity to repeat important messages can facilitate application of evidence, but patient-physician relationships can also pose obstacles.

CONCLUSION

Physicians can take steps to improve care, but success at reducing CV risks depends upon active involvement of many health professionals and community resources. Future guideline implementation should focus on patient-oriented issues, such as comorbidity and treatment preferences.

Anticoagulation in atrial fibrillation. Is there a gap in care for ambulatory patients?

OBJECTIVE

Atrial fibrillation (AF) substantially increases risk of stroke. Evidence suggests that anticoagulation to reduce risk is underused (a "care gap"). Our objectives were to clarify measures of this gap in care by including data from family physicians and to determine why eligible patients were not receiving anticoagulation therapy.

DESIGN

Telephone survey of family physicians regarding specific patients in their practices.

SETTING

Nova Scotia.

PARTICIPANTS

Ambulatory AF patients not taking warfarin who had risk factors that made anticoagulation appropriate.

MAIN OUTCOME MEASURES

Proportion of patients removed from the care gap; reasons given for not giving the remainder anticoagulants.

RESULTS

Half the patients thought to be in the care gap had previously unknown contraindications to anticoagulation, lacked a clear indication for anticoagulation, or were taking warfarin. Patients' refusal and anticipated problems with compliance and monitoring were among the reasons for not giving patients anticoagulants.

CONCLUSION

Adding data from primary care physicians significantly narrowed the care gap. Attention should focus on the remaining reasons for not giving eligible patients anticoagulants.

Evidence-based cardiovascular care in the community: a population-based cross-sectional study

Background

Ischaemic heart disease and congestive heart failure are common and important conditions in family practice. Effective treatments may be underutilized, particularly in women and the elderly. The objective of the study was to determine the rate of prescribing of evidence-based cardiovascular medications and determine if these differed by patient age or sex.

Methods

We conducted a two-year cross-sectional study involving all hospitals in the province of Nova Scotia, Canada. Subjects were all patients admitted with ischaemic heart disease with or without congestive heart failure between 15 October 1997 and 14 October 1999. The main measure was the previous outpatient use of recommended medications. Chi-square analyses followed by multivariate logistic regression analyses were used to examine age-sex differences.

Results

Usage of recommended medications varied from approximately 60% for beta-blockers and angiotensin converting enzyme (ACE) inhibitors to 90% for antihypertensive agents. Patients aged 75 and over were significantly less likely than younger patients to be taking any of the medication classes. Following adjustment for age, there were no significant differences in medication use by sex except among women aged 75 and older who were more likely to be taking beta-blockers than men in the same age group.

Conclusions

The use of evidence-based cardiovascular medications is rising and perhaps approaching reasonable levels for some drug classes. Family physicians should ensure that all eligible patients (prior myocardial infarction, congestive failure) are offered beta-blockers or ACE inhibitors.

A qualitative study of evidence in primary care: what the practitioners are saying

BACKGROUND

Little is known about the impact of evidence-based medicine in primary care. Our objective was to explore the influence of evidence on day-to-day family practice, with specific reference to cardiovascular disease.

METHODS

A total of 9 focus groups were conducted in rural, semi-urban and urban settings in Nova Scotia. The participants were 50 family physicians who had practised in their communities for more than 1 year and who were treating patients with cardiovascular disease.

FINDINGS

Two major themes emerged: evidence in the clinical encounter and the culture of evidence. The family physicians reported thinking about evidence during the clinical encounter but still situated that evidence within the specific context of their patients and their communities. They appreciated evidence that had been appraised, summarized and published as a guideline by an independent national organization. Evidence remained in the forefront of consciousness for a limited time frame. Local specialists, trusted because of their previous successes with shared patient care, were important sources and interpreters of evidence.

INTERPRETATION

Day-to-day family practice offers both obstacles and opportunities for the application of evidence. Although evidence is an important part of clinical practice, it is not absolute and is considered along with many other factors.

Community family medicine teachers' perceptions of their teaching role

OBJECTIVES

Our study explored community preceptors' perceptions of their teaching role, to better understand effective ambulatory and community-based teaching.

METHODS

Bandura's social cognitive theory and Schön's notion of reflective practice guided conceptual development of an interview exploring preceptors' views of their role, teaching goals, teaching techniques, student assessment practices, factors affecting teaching and learning, and balance of patient and student needs. Preceptors reflected also on a significant personal teaching experience. A total of 17 highly student-rated preceptors participated. A trained interviewer conducted each interview; all were transcribed and subjected to content analysis.

RESULTS

Preceptors (male, 14; female, 3) described learner-centred approaches, setting goals jointly with the student. Demonstration, guided practice, observation and feedback were integral to the experience. Preceptors saw student comfort in the environment as key to effective learning; they attempted to maximize students' learning and breadth of experience. They wanted students to understand content, "know-how" and "being a family physician". Patients remained the primary responsibility, but learners' needs were viewed as compatible with that responsibility. Many preceptors perceived a professional responsibility as "role models".

CONCLUSIONS

Preceptors recognized the dynamic environment in which they taught students, and they described strategies which demonstrated how they adapted their teaching to meet the needs of the learner in that environment. These teachers combined learner-centred approaches with sound educational practices, broad learning experiences, attention to student learning and concern for development of professional expertise and judgement. These findings may assist faculty development in family medicine, and other disciplines, in providing effective ambulatory care teaching.

Identifying potential need for cancer palliation in Nova Scotia

OBJECTIVE

To assess the degree to which Nova Scotia cancer patients who may need palliative care are being referred to the comprehensive Halifax-based Palliative Care Program (PCP).

METHODS

The authors conducted a retrospective, population-based study using administrative health data for all adults in Nova Scotia who died of cancer from 1988 to 1994. Proportions and odds ratios (ORs) were used to determine where there were differences in age, sex, place of residence, cancer cause of death, year of death and use of palliative radiotherapy between those who were referred to the PCP at the Halifax Infirmary and those who were not, and between those who were referred late (within 14 days of death) and those who were referred earlier.

RESULTS

Of the 14,494 adults who died of cancer during the study period, 2057 (14.2%) were registered in the PCP. Within Halifax County, 1582 (36.4%) of the 4340 patients with terminal cancer were seen in the PCP. Predictors of PCP registration were residence in Halifax County (OR 19.2, 95% confidence interval [CI] 15.4-23.9), younger age compared with those 85 years of age or older (for those 20-54 years of age, OR 4.9, 95% CI 3.2-7.6; 55-64 years, OR 3.4, 95% CI 2.2-5.1; 65-74 years, OR 3.1, 95% CI 2.1-4.5; 75-84 years, OR 2.1, 95% CI 1.4-3.1), and having received palliative radiation (OR 1.8, 95% CI 1.5-2.2). PCP referral was associated directly with head and neck cancer (OR 5.4, 95% CI 3.0-9.7) and inversely with hematopoietic (OR 0.2, 95% CI 0.4-0.9), lymph node (OR 0.3, 95% CI 0.1-0.4) and lung (OR 0.6, 95% CI 0.4-0.9) cancer. Predictors of late referral (being referred to the PCP within 14 days of death) were age 65-84 years (OR 1.4, 95% CI 1.1-1.8) and 85 years and over (OR 1.8, 95% CI 1.1-3.0), no palliative radiation (OR 2.0, 95% CI 1.4-3.1) and cancer cause of death. People dying within 6 months of diagnosis were somewhat less likely to have been referred to the PCP (OR 0.8, 95% CI 0.6-0.9), but those who were referred were more likely to have been referred late (OR 2.6, 95% CI 2.0-3.5).

INTERPRETATION

Referral to the PCP and earlier rather than late referral were more likely for younger people with terminal cancer, those who received palliative radiation and those living closer to the PCP. Referral rates also varied by cancer cause of death and the time between diagnosis and death.

Dehydration and provision of fluids in palliative care. What is the evidence?

OBJECTIVE

To provide a clinical review of issues surrounding reduced fluid intake in palliative care patients and a practical approach to care for these patients.

DATA SOURCES

Medline was searched from 1980 to 1995 for articles concerning dehydration in dying patients. In addition, the law databases QUICKLAW, WESTLAW, and MEDMAL were searched.

STUDY SELECTION

Key papers were included for discussion in relation to the clinical evidence to treat or withhold treatment and to a representative sample of the social, ethical, and legal issues.

SYNTHESIS

There is little clinical evidence to guide patients, families, or clinicians in treating with reduced fluid intake during the terminal phase of life. Assisting patients to take fluids as a social or symbolic act is recognized, as is the ethical and legal stance that assisting fluid intake should be thought of as a medical therapy.

CONCLUSION

Without sound evidence upon which to base clinical decisions, patients, families, and clinicians are left to balance potential benefits and burdens against the goals of care.

Dehydration symptoms of palliative care cancer patients

A cross-sectional survey of inpatient palliative care subjects (n = 52) was performed to determine the severity and distribution of symptoms thought to be associated with dehydration in terminally ill cancer patients and to clarify the association between the severity of these symptoms and commonly used objective measures of dehydration. Each patient rated the severity of seven symptoms using 100-mm visual analogue scales. The symptoms considered were thirst, dry mouth, bad taste, nausea, pleasure in drinking, fatigue, and pain. Associations were sought between these symptoms and predictor variables (fluid intake, plasma osmolality, sodium, and urea) and confounding variables (age, medications, oral disease, and mouth-care regimen). Mean symptom ratings were thirst 53.8 mm, dry mouth 60.0 mm, bad taste 46.6 mm, nausea 24.0 mm, pleasure in drinking 61.6 mm, fatigue 61.8 mm, and pain 33.5 mm. Using multiple-linear regression, no association could be demonstrated between thirst (the principal outcome of interest) and the predictor or confounding variables. Estimates of the study power performed after completion revealed a 76% chance of detecting a 20-mm difference between high and low fluid intake groups. This study provides the first quantitative estimate of the experience of dehydration symptoms in those with advanced cancer. The symptoms appear to be rated moderately severe, but there is no demonstrable association between severity and fluid intake. Further studies with greater statistical power and more accurate hydration assessment would strengthen our understanding of this association.

The authors examined charts for evidence of the use of intravenous fluids in all patients who died from malignant disease occurring in a tertiary care teaching hospital during a 1-year period. Total lengths of stay and survival time after obtaining “do not resuscitate” orders were longer in those who died without intravenous fluids. More than two-thirds of patients with cancer who died in hospital did so with an intravenous line.

Intravenous fluids and the hospitalized dying: a medical last rite?

The authors examined charts for evidence of the use of intravenous fluids in all patients who died from malignant disease occurring in a tertiary care teaching hospital during a one-year period. Of 106 patients who were identified, 86 received intravenous fluids within their last 30 days of life, and 73 died with an intravenous line running.Intravenous fluid use appeared to be independent of age, sex, language, presence of family members, primary tumour site, presence of metastases, duration of illness, and presence of a "no cardiopulmonary resuscitation" order. Total lengths of stay and survival time after obtaining "do not resuscitate" orders were longer in those who died without intravenous fluids. More than two-thirds of patients with cancer who died in hospital did so with an intravenous line.

Palliative care in medical education at McMaster University

As professionals working within palliative care struggle to find their niche in the academic, administrative and service continuum of patient care, we have a growing desire to share what has been learned with students and colleagues. The opportunities for student physicians to learn the principles and practices of caring for the dying are few. The described curriculum content is dependent on the McMaster philosophy of medical education and the developmental level of the student physician. Areas included are: philosophy of palliative care, communication skills, symptom assessment and control, approach to ethical issues, decision making and interdisciplinary team function. The authors describe the university's current approach in its specific contribution to undergraduate and postgraduate medical education, the continuum throughout those years and an examination of recommendations for the future.
