Avoiding Spending While Meeting Patients' Wishes: A Model of Community-Based Palliative Care Uptake in California from 2014-2022.

BACKGROUND: Community-based palliative care can improve outcomes and avoid unnecessary spending, but the effects of its widespread adoption on health care spending in California is unknown. OBJECTIVE: To estimate the spending avoided if, by 2022, more than 100,000 Californians received community-based palliative care (CBPC) per year. DESIGN: We estimated the 6-month per-patient spending avoided through three mature CBPC programs in California and extrapolated data to predict the total avoided spending statewide over 8 years if enrollment in the three programs proceeded according to our model. RESULTS: If Californians participated in CBPC in the numbers envisioned, in 2014 there would have been a $72 million reduction in intensive hospital based care, while still respecting patients' wishes, and nearly $1.1 billion in spending could be avoided in 2022. Overall hospital spending would be reduced by more than $5.5 billion through 2022. CONCLUSIONS: Existing CBPC programs have the potential to provide care that is both in alignment with patients' wishes and avoids substantial amounts of unnecessary hospital-based spending.

Covered California: The Impact of Provider and Health Plan Market Power on Premiums.

We explain the establishment of Covered California, California's health insurance marketplace. The marketplace uses an active purchaser model, which means that Covered California can selectively contract with some health plans and exclude others. During the 2014 open-enrollment period, it enrolled 1.3 million people, who are covered by eleven health plans. We describe the market shares of health plans in California and in each of the nineteen rating regions. We examine the empirical relationship between measures of provider market concentration--spanning health plans, hospitals, and medical groups--and rating region premiums. To do this, we analyze premiums for silver and bronze plans for specific age groups. We find both medical group concentration and hospital concentration to be positively associated with premiums, while health plan concentration is not statistically significant. We simulate the impact of reducing hospital concentration to levels that would exist in moderately competitive markets. This produces a predicted overall premium reduction of more than 2 percent. However, in three of the nineteen rating regions, the predicted premium reduction was more than 10 percent. These results suggest the importance of provider market concentration on premiums.

Review of Medicare, Medicaid, and Commercial Quality of Care Measures: Considerations for Assessing Accountable Care Organizations.

Accountable care organizations (ACOs) have proliferated under the Affordable Care Act (ACA). If ACOs are to improve health care quality and lower costs, quality measures will be increasingly important in determining if provider consolidations associated with the development of ACOs are achieving their intended purpose. This article assesses quality measurement across public and private sectors. We reviewed available quality measures for a subset of programs in six organizations and assessed the number and domain of measures (structure, process, outcomes, and patient experience). Two-thirds of all quality measures were categorized as process measures. Outcome measures made up nearly 20 percent of measures. Patient experience and structure measures made up approximately 8 percent and 7 percent, respectively. We propose further improvements to quality measurement initiatives. For example, programs that reward providers should consider reward size and distribution within the organization. Quality improvement initiatives should consider what encourages provider buy-in and participation and the effects on populations with disproportionate health care needs. As the focus of quality initiatives may change from year to year, measures should be periodically revisited to ensure continued improvement and sustainability. Finally, we suggest quality measures that regulators could use prior to ACO formation or in the year or two following formation.

Accountable Care Organizations: The National Landscape.

There are now more than seven hundred accountable care organizations (ACOs) in the United States. This article describes some of their most salient characteristics including the number and types of contracts involved, organizational structures, the scope of services offered, care management capabilities, and the development of a three-category taxonomy that can be used to target technical assistance efforts and to examine performance. The current evidence on the performance of ACOs is reviewed. Since California has the largest number of ACOs (N=67) and a history of providing care under risk-bearing contracts, some additional assessments of quality and patient experience are made between California ACOs and non-ACO provider organizations. Six key issues likely to affect future ACO growth and development are discussed, and some potential "diagnostic" indicators for assessing the likelihood of potential antitrust violations are presented.

The Effect of a Care Transition Intervention on the Patient Experience of Older Multi-Lingual Adults in the Safety Net: Results of a Randomized Controlled Trial.

BACKGROUND: The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) and Care Transitions Measure (CTM-3) scores are patient experience measures used to determine hospital value-based purchasing reimbursement. Interventions to improve 30-day readmissions have met with mixed results, but less is known about their potential to improve the patient experience among older ethnically and linguistically diverse adults receiving care at safety-net hospitals. In this study, we assessed the effect of a nurse-led hospital-based care transition intervention on discharge-related patient experience in an older multilingual population of adults hospitalized at a safety-net hospital. METHODS: We randomized 700 inpatients aged 55 and older at an academic urban safety-net hospital. In addition to usual care, intervention participants received inpatient visits by a language-concordant study nurse and post-discharge phone calls from a language-concordant nurse practitioner to reinforce the care plan and to address acute complaints. We measured HCAHPS nursing, medication, and discharge communication domain scores and CTM-3 scores at 30 days after hospital discharge. RESULTS: Of 685 participants who survived to 30 days, 90 % (n = 616) completed follow-up interviews. The mean age was 66.2 years; over half (54.2 %) of the participants had cognitive impairment, and 33.8 % had moderate to severe depression. The majority (62.1 %) of interviews were conducted in English; 23.3 % were conducted in Chinese and 14.6 % in Spanish. Study nurses spent an average of 157 min with intervention participants. Between intervention and usual care participants, CTM-3 scores (80.5 % vs 78.5 %; p = 0.18) and HCAHPS discharge communication domain scores (74.8 % vs 68.7 %; p = 0.11) did not differ, nor did HCAHPS scores in medication (44.5 % vs 53.1 %; p = 0.13) and nursing domains (67.9 % vs 64.9 %; p = 0.43). When stratified by language, no significant differences were seen. CONCLUSION: An inpatient standalone transition-of-care intervention did not improve patient discharge experience. Older multi-lingual and cognitively impaired populations may require higher-intensity interventions post-hospitalization to improve discharge experience outcomes.

Hospitalization-Associated Disability in Adults Admitted to a Safety-Net Hospital.

BACKGROUND: Little is known about hospitalization-associated disability (HAD) in older adults who receive care in safety-net hospitals. OBJECTIVES: To describe HAD and to examine its association with age in adults aged 55 and older hospitalized in a safety-net hospital. DESIGN: Secondary post hoc analysis of a prospective cohort from a discharge intervention trial, the Support from Hospital to Home for Elders. SETTING: Medicine, cardiology, and neurology inpatient services of San Francisco General Hospital, a safety-net hospital. PARTICIPANTS: A total of 583 participants 55 and older who spoke English, Spanish, or Chinese. We determined the incidence of HAD 30 days post-hospitalization and ORs for HAD by age group. MEASUREMENTS: The outcome measure was death or HAD at 30 days after hospital discharge. HAD is defined as a new or additional disability in one or more activities of daily living (ADL) that is present at hospital discharge compared to baseline. Participants' functional status at baseline (2 weeks prior to admission) and 30 days post-discharge was ascertained by self-report of ADL function. RESULTS: Many participants (75.3 %) were functionally independent at baseline. By age group, HAD occurred as follows: 27.4 % in ages 55-59, 22.2 % in ages 60-64, 17.4 % in ages 65-69, 30.3 % in ages 70-79, and 61.7 % in ages 80 or older. Compared to the youngest group, only the adjusted OR for HAD in adults over 80 was significant, at 2.45 (95 % CI 1.17, 5.15). CONCLUSIONS: In adults at a safety-net hospital, HAD occurred in similar proportions among adults aged 55-59 and those aged 70-79, and was highest in the oldest adults, aged ≥ 80. In safety-net hospitals, interventions to reduce HAD among patients 70 years and older should consider expanding age criteria to adults as young as 55.

Functional disability in late-middle-aged and older adults admitted to a safety-net hospital.

OBJECTIVES: To determine the prevalence of preadmission functional disability in late-middle-aged and older safety-net inpatients and to identify characteristics associated with functional disability by age. DESIGN: Cross-sectional analysis. SETTING: Safety-net hospital in San Francisco, California. PARTICIPANTS: English-, Spanish-, and Chinese-speaking community-dwelling individuals aged 55 and older admitted to a safety-net hospital with anticipated return to the community (N = 699). MEASUREMENTS: At hospital admission, participants reported their need for help performing five activities of daily living (ADLs) and seven instrumental activities of daily living (IADLs) 2 weeks before admission. ADL disability was defined as needing help performing one or more ADLs and IADL disability as needing help performing two or more IADLs. Participant characteristics were assessed, including sociodemographic characteristics, health status, health-related behaviors, and health-seeking behaviors. RESULTS: Overall, 28.3% of participants reported that they had an ADL disability 2 weeks before admission, and 40.4% reported an IADL disability. The prevalence of preadmission ADL disability was 28.9% of those aged 55 to 59, 20.7% of those aged 60 to 69, and 41.2% of those aged 70 and older (P < .001). The prevalence of IADL disability had a similar distribution. The characteristics associated with functional disability differed according to age; in participants aged 55 to 59, African Americans had a higher odds of ADL and IADL disability, whereas in participants aged 60 to 69 and aged 70 and older, inadequate health literacy was associated with functional disability. CONCLUSION: Preadmission functional disability is common in individuals aged 55 and older admitted to a safety-net hospital. Late-middle-aged individuals admitted to safety-net hospitals may benefit from models of acute care currently used for older adults that prevent adverse outcomes associated with functional disability.

Support from hospital to home for elders: a randomized trial.

BACKGROUND: Hospitals are implementing discharge support programs to reduce readmissions, and these programs have had mixed success. OBJECTIVE: To examine whether a peridischarge, nurse-led intervention decreased emergency department (ED) visits or readmissions among ethnically and linguistically diverse older patients admitted to a safety-net hospital. DESIGN: Randomized, controlled trial using computer-generated randomization with 1:1 allocation, stratified by language. (Clinical Trials.gov: NCT01221532). SETTING: Publicly funded urban hospital in Northern California. PATIENTS: Hospitalized adults aged 55 years or older with anticipated discharge to the community who spoke English, Spanish, or Chinese (Mandarin or Cantonese). INTERVENTION: Usual care versus in-hospital, one-on-one, self-management education given by a dedicated language-concordant registered nurse combined with a telephone follow-up after discharge from a nurse practitioner. MEASUREMENTS: Staff blinded to the study groups determined ED visits or readmissions to any facility at 30, 90, and 180 days after initial hospital discharge using administrative data from several hospitals. RESULTS: There were 700 low-income, ethnically and linguistically diverse patients with a mean age of 66.2 years (SD, 9.0). The primary outcome of ED visits or readmissions did not differ between the intervention and usual care groups (hazard ratio, 1.26 [95% CI, 0.89 to 1.78] at 30 days, 1.21 [CI, 0.91 to 1.62] at 90 days, and 1.11 [CI, 0.86 to 1.43] at 180 days). LIMITATIONS: This study was done at a single acute-care hospital. There were fewer outcomes than expected, which may have caused the study to be underpowered. CONCLUSION: A nurse-led, in-hospital discharge support intervention did not show a reduction in readmissions or ED visits among diverse, low-income older adults at a safety-net hospital. Although wide CIs preclude firm conclusions, the intervention may have increased ED visits. Alternative readmission prevention strategies should be tested in this population.

"Missing pieces"--functional, social, and environmental barriers to recovery for vulnerable older adults transitioning from hospital to home.

OBJECTIVES: To describe barriers to recovery at home for vulnerable older adults after leaving the hospital. DESIGN: Standard qualitative research techniques, including purposeful sampling of participants according to age, sex, race, and English proficiency, were used to ensure a wide breadth of experiences. All participants were interviewed in their native language (English, Spanish, or Chinese). Two investigators independently coded interviews using the constant comparative method. The entire research team, with diverse backgrounds in primary care, hospital medicine, geriatrics, and nursing, performed thematic analysis. SETTING: Urban public safety-net teaching hospital. PARTICIPANTS: Vulnerable older adults (low income and health literacy, limited English proficiency) enrolled in a larger discharge interventional study. MEASUREMENTS: Qualitative data (participant quotations) were organized into themes. RESULTS: Twenty-four individuals with a mean age of 63 (range 55-84), 66% male, 67% nonwhite, 16% Spanish speaking, 16% Chinese speaking were interviewed. An overarching theme of "missing pieces" was identified in the plan for postdischarge recovery at home, from which three specific subthemes emerged: functional limitations and difficulty with mobility and self-care tasks, social isolation and lack of support from family and friends, and challenges from poverty and the built environment at home. In contrast, participants described mostly supportive experiences with traditional focuses of transition, care such as following prescribed medication and diet regimens. CONCLUSION: Hospital-based discharge interventions that focus on traditional aspects of care may overlook social and functional gaps in postdischarge care at home for vulnerable older adults. Postdischarge interventions that address these challenges may be necessary to reduce readmissions in this population.

Engaging individuals recently released from prison into primary care: a randomized trial.

OBJECTIVES: Individuals released from prison have high rates of chronic conditions but minimal engagement in primary care. We compared 2 interventions designed to improve primary care engagement and reduce acute care utilization: Transitions Clinic, a primary care-based care management program with a community health worker, versus expedited primary care. METHODS: We performed a randomized controlled trial from 2007 to 2009 among 200 recently released prisoners who had a chronic medical condition or were older than 50 years. We abstracted 12-month outcomes from an electronic repository available from the safety-net health care system. Main outcomes were (1) primary care utilization (2 or more visits to the assigned primary care clinic) and (2) emergency department (ED) utilization (the proportion of participants making any ED visit). RESULTS: Both groups had similar rates of primary care utilization (37.7% vs 47.1%; P = .18). Transitions Clinic participants had lower rates of ED utilization (25.5% vs 39.2%; P = .04). CONCLUSIONS: Chronically ill patients leaving prison will engage in primary care if provided early access. The addition of a primary care-based care management program tailored for returning prisoners reduces ED utilization over expedited primary care.

Factors affecting psychiatric inpatient hospitalization from a psychiatric emergency service.

OBJECTIVE: As a gateway to the mental health system, psychiatric emergency services (PES) are charged with assessing a heterogeneous array of short-term and long-term psychiatric crises. However, few studies have examined factors associated with inpatient psychiatric hospitalization following PES in a racially diverse sample. We examine the demographic, service use and clinical factors associated with inpatient hospitalization and differences in predisposing factors by race and ethnicity. METHOD: Three months of consecutive admissions to San Francisco's only 24-h PES (N = 1,305) were reviewed. Logistic regression was used to estimate the associations between demographic, service use, and clinical factors and inpatient psychiatric hospitalization. We then estimated separate models for Asians, Blacks, Latinos and Whites. RESULTS: Clinical severity was a consistent predictor of hospitalization. However, age, gender, race/ethnicity, homelessness and employment status were all significant related to hospitalization. Alcohol and drug use were associated with lower probability of inpatient admission, however specific substances appear particularly salient for different racial/ethnic groups. DISCUSSION: While clinical characteristics played an essential role in disposition decisions, these results point to the importance of factors external to PES. Individual and community factors that affect use of psychiatric emergency services merit additional focused attention.

Effect of racial and ethnic composition of neighborhoods in San Francisco on rates of mental health-related 911 calls.

OBJECTIVE: This study investigated the association between the racial and ethnic residential composition of San Francisco neighborhoods and the rate of mental health-related 911 calls. METHODS: A total of 1,341,608 emergency calls (28,197 calls related to mental health) to San Francisco's 911 system were made from January 2001 through June 2003. Police sector data in the call records were overlaid onto U.S. census tracts to estimate sector demographic and socioeconomic characteristics. Negative binomial regression was used to estimate the association between the percentage of black, Asian, Latino, and white residents and rates of mental health-related calls. RESULTS: A one-point increase in a sector's percentage of black residents was associated with a lower rate of mental health-related calls (incidence rate ratio=.99, p<.05). A sector's percentage of Asian and Latino residents had no significant effect. CONCLUSIONS: The observed relationship between the percentage of black residents and mental health-related calls is not consistent with known emergency mental health service utilization patterns.

Unemployment and civil commitment: a test of the intolerance hypothesis.

We theorize that the reported association between economic indicators and the incidence of civil commitment for mental illness may result, at least in part, from reduced tolerance in the community for impaired behavior among minorities. Earlier work suggests that economically induced intolerance will be focused primarily on minority males. Based on this literature, we hypothesize that the median level of functioning among African-American males subjected to civil commitment will vary positively with earlier changes in the unemployment rate. The test applies Box-Jenkins methods to 156 months (August 1985-July 1998) of data from California. Consistent with theory, results support the hypothesis.

Rates of unemployment and incidence of police-initiated examinations for involuntary hospitalization in Florida.

OBJECTIVE: This study tested the hypothesis that contraction of regional economies affects the incidence of involuntary admissions to psychiatric emergency services by reducing community tolerance for persons perceived as threatening to others. METHODS: This hypothesis was tested with time-series analyses of the relationship between initial claims for unemployment in Florida between July 4, 1999, and June 28, 2003, and the weekly number of men and women presented by police to be examined for involuntary psychiatric hospitalization because of danger to others. The analyses controlled for admissions presented by mental health professionals because of danger to others and for admissions presented by police because of neglect or disability. RESULTS: When the analyses controlled for autocorrelation and other covariates, claims for unemployment insurance were significantly associated with the number of men presented by police for danger to others. During the study period, police presented 5,897 men for examination because of danger to others. Increased unemployment claims were associated with approximately 309 more men being presented for examination than expected from prior presentation rates and from the number presented by mental health professionals for danger to others and by police for neglect or disability. No such association was found for women. CONCLUSIONS: Consistent with theory, this study found that presentations for involuntary admission to psychiatric services increased after contractions in the labor market. Combining the methods of this study with econometric forecasting may allow providers to anticipate better the need for psychiatric services.

Public health care utilization in a cohort of homeless adult applicants to a supportive housing program.

Supportive housing is subsidized housing with on-site or closely linked services for chronically homeless persons. Most literature describing the effects of supportive housing on health service utilization does not describe use across multiple domains of services. We conducted a retrospective cohort study of 249 applicants to a supportive housing program; 114 (45.7%) were housed in the program. We describe the pattern of service use across multiple domains (housing, physical health care, mental health care, substance abuse treatment). We examine whether enrollment in supportive housing was associated with decreased use of acute health services (emergency department (ED) and inpatient medical hospitalizations) and increased use of ambulatory services (ambulatory medical and generalist care, mental health, and substance abuse treatment) as compared to those eligible but not enrolled. Participants in both groups exhibited high rates of service utilization. We did not find a difference in change in utilization patterns between the two groups [those that received housing (intervention) and those that applied, were eligible, but did not establish residency (usual care group)] comparing the two years prior to the intervention to the two years after. The finding of high rates of maintenance of housing is, in itself, noteworthy. The consistently high use of services across multiple domains and across multiple years speaks to the level of infirmity of this population and the costs of caring for its members.

Involuntary psychiatric examinations for danger to others in Florida after the attacks of September 11, 2001.

OBJECTIVE: Theories of perceived risk state that when people feel threatened, they will react more strongly than they would otherwise. This study tested the hypothesis that evaluations for involuntary psychiatric hospitalizations that were initiated by law enforcement personnel in Florida increased in the weeks after the attacks of September 11, 2001. METHODS: The authors applied interrupted time-series designs to determine whether there was a relationship between the number of involuntary psychiatric examinations initiated by law enforcement officials and the attacks of September 11, 2001. They examined the number of psychiatric evaluations of men and women who were considered to be mentally ill and harmful to others by law enforcement personnel in Florida during seven-day periods ("areal" weeks) that began with Tuesday, July 6, 1999, and ended with Monday, December 31, 2001 (because September 11, 2001, fell on a Tuesday). RESULTS: Over the 130 weeks of the study, law enforcement officials initiated examinations of an average of 25.96 men and 13.47 women per areal week. Law enforcement officials initiated examinations of approximately 14 more women than expected in the areal week that began with September 11, 2001. During the three areal weeks that began with September 18, 2001, a total of 34 more men than expected were presented for evaluation. These findings cannot be attributed to trends, seasonality, other cycles, or the tendency of the examination time series to remain elevated or depressed after high or low values in the series. CONCLUSIONS: Perceived general risk in a community may increase the likelihood that law enforcement personnel and the persons who summon them perceive persons with mental illness as imminently harmful. The public health response to any future terror attacks should include efforts to alert psychiatric service providers to the possibility of lower community tolerance for mental illness in the aftermath of an attack.

Chlamydia screening of youth and young adults in non-clinical settings throughout California.

BACKGROUND: Urine-based chlamydia tests enable screening in non-clinical settings. GOAL: The goal of this study was to determine the prevalence of chlamydia infection among high-risk youth and young adults in non-clinical settings. DESIGN: County sexually transmitted disease (STD) programs implemented chlamydia screening projects in non-clinical settings using nucleic acid amplification tests. Demographic and access to care data were collected. RESULTS: Overall, 16,279 female and male youth were screened for chlamydia in 24 counties throughout California. The 158 screening venues included 32 educational, 32 correctional, and 94 community-based settings. Chlamydia infection rates varied significantly by gender, age, and venue type. Among females, the highest prevalence was found in jail settings (14.6%), juvenile detention (13.0%), and alternative schools (10.0%). Among males, the highest prevalence was found in jail (7.9%) and juvenile detention (5.8%). Venue types that serve populations with poor access to care and high rates of infection were identified. CONCLUSIONS: Screening projects in non-clinical settings identify high-risk youth in need of STD care, improve access to STD screening and education, and foster local collaborations.

Psychiatric emergencies after the terrorist attacks of September 11, 2001.

OBJECTIVE: Population surveys suggest that the events of September 11, 2001, resulted in psychiatric emergencies in U.S. communities. This study tested the extent of such emergencies in San Francisco. METHOD: S: Interrupted time-series designs were applied to counts of emergency calls to the police during the 424-day period beginning January 1, 2001, and of voluntary and coerced admissions to psychiatric emergency services during the 1620-day period beginning July 1, 1997. RESULTS: The number of men and women who were coerced into treatment increased significantly on Thursday, September 13, but the number of voluntary admissions was as expected. The number of telephone calls from citizens that police dispatchers judged to be mental health related increased significantly on Wednesday, September 12, and remained elevated through September 13. Several additional analyses were conducted to test the stability of the findings, and the results were essentially unchanged. CONCLUSIONS: The events of September 11 may not have induced emergent mental illness in U.S. communities at relatively great distance from the attacks. However, it is possible that persons with severe mental illness were either more evident to or less tolerated by the community.
