Family physician continuity of care and emergency department use in end-of-life cancer care.

Background. Despite cancer patients preferring to spend their last days out‐of‐hospital, many make difficult visits to the emergency department (ED). Family physician continuity of care has been shown in some clinical situations to reduce ED utilization. Objective. To determine if greater family physician continuity of care for cancer patients during the end‐of‐life is associated with less ED utilization. Method. This retrospective, population‐based study involved secondary analysis of linked administrative data files for 1992 to 1997. Sources included the Nova Scotia Cancer Registry, Vital Statistics, the Queen Elizabeth II Health Sciences Center Oncology Patient Information System and Palliative Care Program (PCP), Hospital Admissions/Separation data, and Physician Services information. Subjects included adults with a recorded date of cancer diagnosis who died of cancer and who had made at least three visits to a family physician during their last 6 months of life. The relationship between total ED visits and family physician continuity of care, developed using the Modified Modified Continuity Index (MMCI), was examined using negative binomial regression with adjustments for survival, year of death, sex, age, cancer type, region, PCP admission, specialty visits, hospital days, death location, income quintile, and total ambulatory visits. Results. In total, 8702 subjects made 11,551 ED visits (median = 1.0); median MMCI was 0.83. Adjusted results indicate those experiencing low continuity (MMCI < 0.5) made 3.9 times more ED visits (rate ratio [RR] = 3.93; 95% CI [CI] = 3.57–4.34) than those experiencing high continuity (MMCI ≥ 0.8) and patients experiencing moderate continuity (MMCI = 0.5–0.8) made twice as many ED visits (RR = 2.28; CI = 2.15–2.42). Conclusion. Given this significant association between family physician continuity of care and ED visits during the end‐of‐life, and given international trends to reform primary care, active planning of strategies to facilitate such continuity should be encouraged.

Towards using administrative databases to measure population-based indicators of quality of end-of-life care : testing the methodology

This study is concerned with methods to measure population-based indicators of quality end-of-life care. Using a retrospective cohort approach, we assessed the feasibility, validity and reliability of using administrative databases to measure quality indicators of end-of-life care in two Canadian provinces. The study sample consisted of all females who died of breast cancer between 1 January 1998 and 31 December 2002, in Nova Scotia or Ontario, Canada. From an initial list of 19 quality indicators selected from the literature, seven were determined to be fully measurable in both provinces. An additional seven indicators in one province and three in the other province were partially measurable. Tests comparing administrative and chart data show a high level of agreement with inter-rater reliability, confirming consistency in the chart abstraction process. Using administrative data is an efficient, population-based method to monitor quality of care which can compliment other methods, such as qualitative and purposefully collected clinical data.

Primary care continuity and location of death for those with cancer.

BACKGROUND Continuity of primary care is known to be associated with both improved processes and outcomes of care. Despite continuity being a desired attribute of end-of-life care and despite the desire by most patients with cancer to die at home, there has been no health services research examining this relationship. AIM To examine the association between family physician continuity of care and the location of death for patients with cancer. DESIGN OF STUDY A retrospective population-based study involving secondary data analysis of four linked administrative health databases spanning 6 years of information (1992-1997). SETTING Nova Scotia, Canada Participants: All those who died of cancer from 1992 to 1997 and had made at least three ambulatory visits to a family physician. METHODS The relationship of provider continuity of care and an out-of-hospital death was examined using logistic regression. RESULTS Out-of-hospital deaths accounted for 31.6% of the 9714 deaths in the study population. The mean provider continuity of care was 0.78 (standard deviation [SD] 0.22). Those who died out-of-hospital had a greater odds of having received high provider continuity (adjusted odds ratio [OR] = 1.54, 95% confidence interval [CI] = 1.22, 1.93) when compared to those who died in-hospital. There appears to be a modification of this effect by gender with a significant association found for males and not for females. The trends in the point estimates are, however, similar for both sexes. CONCLUSIONS This study demonstrates an association between family physician continuity of care and the location of death for those with advanced cancer. Such continuity should be fostered in the development of models of integrated service delivery for end-of-life care.

A population-based study of age inequalities in access to palliative care among cancer patients.

Background:Inequalities in access to palliative care programs (PCP) by age have been shown to exist in Canada and elsewhere. Few studies have been able to provide greater insight by simultaneously adjusting for multiple demographic, health service, and socio-cultural indicators. Objective:To re-examine the relationship between age and registration to specialized community-based PCP programs among cancer patients and identify the multiple indicators contributing to these inequalities. Methods:This retrospective, population-based study was a secondary data analysis of linked individual level information extracted from 6 administrative health databases and contextual (neighborhood level) data from provincial and census information. Subjects included all adults who died due to cancer between 1998 and 2003 living within 2 District Health Authorities in the province of Nova Scotia, Canada. The relationship between registration in a PCP and age was examined using hierarchical nonlinear regression modeling techniques. Identification of potential patient and ecologic contributing indicators was guided by Andersens conceptual model of health service utilization. Results:Overall, 66% of 7511 subjects were registered with a PCP. Older subjects were significantly less likely than those <65 years of age to be registered with a PCP, in particular those aged 85 years and older (adjusted odds ratio: 0.4; 95% confidence interval: 0.3–0.5). Distance to the closest cancer center had a major impact on registration. Conclusions:Age continues to be a significant predictor of PCP registration in Nova Scotia even after controlling for the confounding effects of many new demographic, health service, and ecologic indicators.

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

BackgroundDuring 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.MethodsDesign 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.ResultsIn 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).ConclusionDespite 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.

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

BackgroundTransitions 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.MethodsTransition 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.ResultsOver 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.ConclusionA 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.

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.

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

BackgroundPatients 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.MethodsSubjects 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.ResultsIn 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.ConclusionOur 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.

Does Increasing Home Care Nursing Reduce Emergency Department Visits at the End of Life? A Population-Based Cohort Study of Cancer Decedents

CONTEXT Despite being commonplace in health care systems, little research has described home care nursings effectiveness to reduce acute care use at the end of life. OBJECTIVES To examine the temporal association between home care nursing rate on emergency department (ED) visit rate in the subsequent week during the last six months of life. METHODS We conducted a retrospective cohort study of end-of-life cancer decedents in Ontario, Canada, from 2004 to 2009 by linking administrative databases. We examined the association between home care nursing rate of one week with the ED rate in the subsequent week closer to death, controlling for covariates and repeated measures among decedents. Nursing was dichotomized into standard and end-of-life care intent. RESULTS Our cohort included 54,576 decedents who used home care nursing services in the last six months before death, where 85% had an ED visit and 68% received end-of-life home care nursing. Patients receiving end-of-life nursing at any week had a significantly reduced ED rate in the subsequent week of 31% (relative rate [RR] 0.69; 95% confidence interval [CI] 0.68, 0.71) compared with standard nursing. In the last month of life, receiving end-of-life nursing and standard nursing rate of more than five hours/week was associated with a decreased ED rate of 41% (RR 0.59, 95% CI 0.58, 0.61) and 32% (RR 0.68, 95% CI 0.66, 0.70), respectively, compared with standard nursing of one hour/week. CONCLUSION Our study showed a temporal association between receiving end-of-life nursing in a given week during the last six months of life, and of more standard nursing in the last month of life, with a reduced ED rate in the subsequent week.
