Impact of physician-based palliative care delivery models on health care utilization outcomes: A population-based retrospective cohort study

Association between Inappropriate End-of-Life Cancer Care and Specialist Palliative Care: A Retrospective Observational Study in Two Acute Care Hospitals

A substantial number of patients with life-threatening illnesses like cancer receive inappropriate end-of-life care. Improving their quality of end-of-life care is a priority for patients and their families and for public health. To investigate the association between provision, timing, and initial setting of hospital-based specialist palliative care and potentially inappropriate end-of-life care for patients with cancer in two acute care hospitals in the Netherlands, we conducted a retrospective observational study using hospital administrative databases. All adults diagnosed with or treated for cancer in the year preceding their death in 2018 or 2019 were included. The main exposure was hospital-based specialist palliative care initiated >30 days before death. The outcome measures in the last 30 days of life were six quality indicators for inappropriate end-of-life care (≥2 ED-visits, ≥2 hospital admissions, >14 days hospitalization, ICU-admission, chemotherapy, hospital death). We identified 2603 deceased patients, of whom 14% (n = 359) received specialist palliative care >30 days before death (exposure group). Overall, 27% (n = 690) received potentially inappropriate end-of-life care: 19% in the exposure group, versus 28% in the non-exposure group (p < 0.001). The exposure group was 45% less likely to receive potentially inappropriate end-of-life care (AOR 0.55; 95% CI 0.41 to 0.73). Early (>90 days) and late (≤90 and >30 days) initiation of specialist palliative care, as well as outpatient and inpatient initiation, were all associated with less potentially inappropriate end-of-life care (AOR 0.49; 0.62; 0.32; 0.64, respectively). Thus, timely access to hospital-based specialist palliative care is associated with less potentially inappropriate end-of-life care for patients with cancer. The outpatient initiation of specialist palliative care seems to enhance this result.

Association of patient sex with use of palliative care in Ontario, Canada: a population-based study

BACKGROUND

It is unclear whether there are sex-based differences in use of palliative care near the end of life. The objective of this study was to measure the association between sex and palliative care use.

METHODS

We performed a population-based retrospective cohort study of all patients aged 18 years or older in the last year of life who died in Ontario, Canada, between 2010 and 2018. The primary exposure was patient biologic sex (male or female). The primary outcome was receipt of physician-delivered palliative care; secondary outcomes were approach to in-hospital palliative care and sex concordance of the patient and referring physician. We used multivariable modified Poisson regression to measure the association between patient sex and palliative care receipt, as well as patient-physician sex concordance.

RESULTS

There were 706 722 patients (354 657 females [50.2%], median age 80 yr [interquartile range 69-87 yr]) in the study cohort, 377 498 (53.4%) of whom received physician-delivered palliative care. After adjustment for age and selected comorbidities, female sex was associated with a 9% relative increase (adjusted relative risk [RR] 1.09, 95% CI 1.08-1.10) in receipt of physician-delivered palliative care. Female patients were 16% more likely than male patients (adjusted RR 1.14, 95% CI 1.14-1.18) to have had their first hospital admission in their final year of life categorized as having a likely palliative intent. Female patients were 18% more likely than male patients (RR 1.18, 95% CI 1.17-1.19) to have had a female referring physician, and male patients were 20% more likely than female patients (adjusted RR 1.20, CI 1.19-1.21) to have had a male referring physician.

INTERPRETATION

After adjustment for age and comorbidities, male patients were slightly less likely than female patients to have received physician-delivered palliative care, and female patients were more likely than male patients to have had their first hospital admission in their final year of life categorized as having a likely palliative care intent. These results may reflect a between-sex difference in overall end-of-life care preferences or sex differences in decision-making influenced by patient-specific factors; further studies exploring how these factors affect end-of-life decision-making are required.

Physician home visits in Ontario: a cross-sectional analysis of patient characteristics and postvisit use of health care services

BACKGROUND

It is unknown how much of current physician home visit volume is driven by low-complexity or low-continuity visits. Our objectives were to measure physician home visit volumes and costs in Ontario from 2005/06 to 2018/19, and to compare patient characteristics and postvisit use of health care services across home visit types.

METHODS

This was a retrospective cross-sectional study using health administrative data. We examined annual physician home visit volumes and costs from 2005/06 to 2018/19 in Ontario, and characteristics and postvisit use of health care services of residents who received at least 1 home visit from any physician in 2014/15 to 2018/19. We categorized home visits as palliative, provided to a patient who also received home care services or "other," and compared characteristics and outcomes between groups.

RESULTS

A total of 4 418 334 physician home visits were performed between 2005/06 and 2018/19. More than half (2 256 667 [51.1%]) were classified as "other" and accounted for 39.1% ($22 million) of total annual physician billing costs. From 2014/15 to 2018/19, of the 413 057 home visit patients, 240 933 (58.3%) were adults aged 65 or more, and 323 283 (78.3%) lived in large urban areas. Compared to the palliative care and home care groups, the "other" group was younger, had fewer comorbidities, and had lower rates of emergency department visits and hospital admissions in the 30 days after the visit.

INTERPRETATION

About half of physician home visits in 2014/15 to 2018/19 were to patients who were receiving neither palliative care nor home care, a group that was younger and healthier, and had low use of health care services after the visit. There is an opportunity to refine policy tools to target patients most likely to benefit from physician home visits.

Specialist palliative care classification: typology development

OBJECTIVES

The heterogeneity of specialist palliative care services requires a classification to enable a clear description and comparison. In Germany, specialist palliative care is provided by palliative care units, palliative care advisory teams in hospitals and palliative home care teams. The differentiation between the three care settings can serve as a first level of classification. However, due to profound variations in regulatory structures and financing systems, services within each setting are heterogeneous and characteristics remain unclear, which impedes quality management. Further characteristics of specialist palliative care models need to be considered to allow for differentiation. Thus, services should be described on a polyhierarchical basis, such as a typology, representing relevant characteristics. We aimed at the development of a comprehensive classification to facilitate the description and differentiation of specialist palliative care models.

METHODS

Qualitative study including the development of a literature based, preliminary list of structural and processual characteristics, expert interviews and focus groups. Eleven interviews from May to June 2020 and two focus groups, with seven and nine participants each, in January 2021.

RESULTS

Several structure and process characteristics were identified as suitable features for the specification of specialist palliative care in Germany. A classification in form of a typology including relevant characteristics has been developed.

CONCLUSIONS

The advanced typology refines the existing level of differentiation within specialist palliative care services in Germany and paves the way for an improved understanding of services. This deeper insight into structure and process characteristics of specialist palliative care is necessary internationally.

Inpatient Palliative Care Is Associated with the Receipt of Palliative Care in the Community after Hospital Discharge: A Retrospective Cohort Study

Background: For hospitalized patients with palliative care needs, there is little evidence on whether postdischarge outcomes differ if inpatient palliative care was delivered by a palliative care specialist or nonspecialist/generalist. Objective: To evaluate relationships between inpatient palliative care involvement and physician-delivered palliative care in the community after hospital discharge among individuals with limited life expectancy. Design: Population-based retrospective cohort study using administrative health data. Settings/Subjects: Adults with a predicted median survival of six months or less admitted to acute care hospitals in Ontario, Canada, between April 1, 2013, and March 31, 2017, and discharged to the community. Measurements: Inpatient palliative care involvement was classified as high (e.g., palliative care unit), medium (e.g., palliative care specialist consult), low (e.g., generalist-delivered palliative care), or none. Community palliative care included outpatient and home and clinic visits three weeks postdischarge. Results: Among 3660 hospitalized adults, 82 (2.2%) received inpatient palliative care with high level of involvement, 462 (12.6%) with medium level of involvement, 525 (14.3%) with low level of involvement, and 2591 (70.8%) had no inpatient palliative care. Patients who received inpatient palliative care were more likely to receive community palliative care after discharge than those who received no inpatient palliative care. These associations were stronger among patients who received high/medium palliative care involvement than patients who received low palliative care involvement. Conclusions: Inpatient palliative care, including that delivered by generalists, is associated with an increased likelihood of community palliative care after discharge. Increased inpatient generalist palliative care may help support patients' palliative care needs.
