Physician Financial Incentives to Reduce Unplanned Hospital Readmissions: an Interrupted Time Series Analysis

Impact of the health policy for interdisciplinary collaborative rehabilitation practices in intensive care units: A difference-in-differences analysis in Japan

BACKGROUND

Early rehabilitation in intensive care units (ICUs) may be beneficial but is not routinely performed for adults with critical illness. In April 2018, the Japanese government introduced a health policy to provide financial incentives to hospitals that met the requirements of interdisciplinary collaboration and had teams specialized in ICU rehabilitation practices.

OBJECTIVES

The present study aimed to investigate whether the health policy is associated with improved clinical practices of ICU rehabilitation.

METHODS

Using a nationwide administrative inpatient database and hospital statistics data from Japan, we identified hospitals that admitted adult patients to the ICU within two days of hospital admission from April 2016 to March 2019. Using hospital-level propensity score matching, we created matched cohorts of 101,203 patients from 108 intervention hospitals that introduced the health policy, and 106,703 patients from 108 control hospitals that did not. We then conducted patient-level difference-in-differences analyses to examine changes in the percentage of patients from the intervention and control hospitals, who underwent early ICU rehabilitation within two days of ICU admission before and after the implementation of the health policy.

RESULTS

In the intervention group, patients undergoing early ICU rehabilitation increased from 10% and 36% after the policy implementation. In the control group, it increased from 11% to 13%. The difference-in-difference in the percentage of patients who underwent early ICU rehabilitation between the two groups was 24% (95% confidence interval, 19%-29%).

CONCLUSIONS

Early ICU rehabilitation can be facilitated by financial incentives for hospitals that engage in interdisciplinary collaboration with specialist teams.

IMPLICATIONS FOR CLINICAL PRACTICE

Our Findings are relevant for hospital administrators, professional organizations, and policymakers in other nations considering strategies to support the additional deployment burdens of early ICU rehabilitation. Future studies need to explore the long-term effects and sustainability of the observed improvements in ICU rehabilitation practices.

Population-Based Trends in Complexity of Hospital Inpatients

Importance

Clinical experience suggests that hospital inpatients have become more complex over time, but few studies have evaluated this impression.

Objective

To assess whether there has been an increase in measures of hospital inpatient complexity over a 15-year period.

Design, Setting and Participants

This cohort study used population-based administrative health data from nonelective hospitalizations from April 1, 2002, to January 31, 2017, to describe trends in the complexity of inpatients in British Columbia, Canada. Hospitalizations were included for individuals 18 years and older and for which the most responsible diagnosis did not correspond to pregnancy, childbirth, the puerperal period, or the perinatal period. Data analysis was performed from July to November 2023.

Exposure

The passage of time (15-year study interval).

Main Outcomes and Measures

Measures of complexity included patient characteristics at the time of admission (eg, advanced age, multimorbidity, polypharmacy, recent hospitalization), features of the index hospitalization (eg, admission via the emergency department, multiple acute medical problems, use of intensive care, prolonged length of stay, in-hospital adverse events, in-hospital death), and 30-day outcomes after hospital discharge (eg, unplanned readmission, all-cause mortality). Logistic regression was used to estimate the relative change in each measure of complexity over the entire 15-year study interval.

Results

The final study cohort included 3 367 463 nonelective acute care hospital admissions occurring among 1 272 444 unique individuals (median [IQR] age, 66 [48-79] years; 49.1% female and 50.8% male individuals). Relative to the beginning of the study interval, inpatients at the end of the study interval were more likely to have been admitted via the emergency department (odds ratio [OR], 2.74; 95% CI, 2.71-2.77), to have multimorbidity (OR, 1.50; 95% CI, 1.47-1.53) and polypharmacy (OR, 1.82; 95% CI, 1.78-1.85) at presentation, to receive treatment for 5 or more acute medical issues (OR, 2.06; 95% CI, 2.02-2.09), and to experience an in-hospital adverse event (OR, 1.20; 95% CI, 1.19-1.22). The likelihood of an intensive care unit stay and of in-hospital death declined over the study interval (OR, 0.96; 95% CI, 0.95-0.97, and OR, 0.81; 95% CI, 0.80-0.83, respectively), but the risks of unplanned readmission and death in the 30 days after discharge increased (OR, 1.14; 95% CI, 1.12-1.16, and OR, 1.28; 95% CI, 1.25-1.31, respectively).

Conclusions and Relevance

By most measures, hospital inpatients have become more complex over time. Health system planning should account for these trends.

Hospital Readmissions Among Persons With Human Immunodeficiency Virus in the United States and Canada, 2005-2018: A Collaboration of Cohort Studies

BACKGROUND

Hospital readmission trends for persons with human immunodeficiency virus (PWH) in North America in the context of policy changes, improved antiretroviral therapy (ART), and aging are not well-known. We examined readmissions during 2005-2018 among adult PWH in NA-ACCORD.

METHODS

Linear risk regression estimated calendar trends in 30-day readmissions, adjusted for demographics, CD4 count, AIDS history, virologic suppression (<400 copies/mL), and cohort.

RESULTS

We examined 20 189 hospitalizations among 8823 PWH (73% cisgender men, 38% White, 38% Black). PWH hospitalized in 2018 versus 2005 had higher median age (54 vs 44 years), CD4 count (469 vs 274 cells/μL), and virologic suppression (83% vs 49%). Unadjusted 30-day readmissions decreased from 20.1% (95% confidence interval [CI], 17.9%-22.3%) in 2005 to 16.3% (95% CI, 14.1%-18.5%) in 2018. Absolute annual trends were -0.34% (95% CI, -.48% to -.19%) in unadjusted and -0.19% (95% CI, -.35% to -.02%) in adjusted analyses. By index hospitalization reason, there were significant adjusted decreases only for cardiovascular and psychiatric hospitalizations. Readmission reason was most frequently in the same diagnostic category as the index hospitalization.

CONCLUSIONS

Readmissions decreased over 2005-2018 but remained higher than the general population's. Significant decreases after adjusting for CD4 count and virologic suppression suggest that factors alongside improved ART contributed to lower readmissions. Efforts are needed to further prevent readmissions in PWH.

Evaluation of the Retrospective LACE Index in Predicting the Risk of Readmission in Patients with Hereditary Angioedema in an Emergency Department

This study aimed to calculate the LACE index in patients who admitted to the emergency department (ED) with hereditary angioedema (HA) diagnosed and to predict recurrent admissions of patients. In this single-center study, patients aged 18 or higher who were admitted to the ED diagnosed with HA were included over a 12-year period. 35 patients diagnosed with code E88.0 were evaluated according to electronic file records. The number of admissions to the ED in the last 6 months was 2. The LACE index was 4, and risk was 71.4%. The patients admitted to the hospital in the last 30 days had a higher rate of admission to the hospital in the last 6 months (p < 0.001). The LACE index at admission predicted 30 days admission with (AUC = 0.75, 95% CI (0.56-0.91)) acceptable discrimination. The LACE index and the number of admissions in the last 6 months included in the evaluation can be considered predictive in recurrent ED admissions of HA patients. However, the distribution of LACE-risk groups is no priority. Therefore, the low-, medium-, or high-risk level of LACE index values should be not taken into consideration in readmission of such patients.

Physician Financial Incentives for Use of Outpatient Intravenous Antimicrobial Therapy: An Interrupted Time Series Analysis

BACKGROUND

In 2011, policymakers in British Columbia introduced a fee-for-service payment to incentivize infectious diseases physicians to supervise outpatient parenteral antimicrobial therapy (OPAT). Whether this policy increased use of OPAT remains uncertain.

METHODS

We conducted a retrospective cohort study using population-based administrative data over a 14-year period (2004-2018). We focused on infections that required intravenous antimicrobials for ≥10 days (eg, osteomyelitis, joint infection, endocarditis) and used the monthly proportion of index hospitalizations with a length of stay shorter than the guideline-recommended "usual duration of intravenous antimicrobials" (LOS < UDIVA) as a surrogate for population-level OPAT use. We used interrupted time series analysis to determine whether policy introduction increased the proportion of hospitalizations with LOS < UDIVA.

RESULTS

We identified 18 513 eligible hospitalizations. In the pre-policy period, 82.3% of hospitalizations exhibited LOS < UDIVA. Introduction of the incentive was not associated with a change in the proportion of hospitalizations with LOS < UDIVA, suggesting that the policy intervention did not increase OPAT use (step change, -0.06%; 95% confidence interval [CI], -2.69% to 2.58%; P = .97 and slope change, -0.001% per month; 95% CI, -.056% to .055%; P = .98).

CONCLUSIONS

The introduction of a financial incentive for physicians did not appear to increase OPAT use. Policymakers should consider modifying the incentive design or addressing organizational barriers to expanded OPAT use.

Evaluating a Care Management Program for Dual-Eligible Beneficiaries: Evidence from Rhode Island

As health systems attempt to contain utilization and costs, care management programs are proliferating. However, there are mixed findings on their impact. In 2018, Rhode Island initiated a care management program for dually eligible Medicare and Medicaid beneficiaries at high risk of hospitalization or institutionalization. The objective of this study is to evaluate the association between health care utilization and costs and care management for dual-eligible participants (n = 169). The authors employed an interrupted time series analysis of administrative claims data using the Rhode Island All Payer Claims Database, which includes data from all major payers in the state, for 11 quarters (January 1, 2017 until September 1, 2019). On average, participants were younger (46.2% were 19-64 years of age vs. 41.9% of non-participants), female (71% vs. 62.6% of non-participants), and had a higher comorbidity burden (more commonly had anemia, atrial fibrillation, chronic kidney disease, chronic obstructive pulmonary disease, depression, diabetes, heart failure, hyperlipidemia, hypertension, ischemic heart disease, and stroke). Participation was associated with significantly fewer hospital admissions (118 fewer admissions per 1000 admissions per quarter; 95% confidence interval [CI] -11 to -22), and a reduction in Medicaid ($1841 less spent per quarter, 95% CI -2407 to -1275) and total ($2570 less spent per quarter; 95% CI -$4645 to -$495) costs. Participation was not significantly associated with a change in Emergency Department (ED) visits, preventable ED visits, Skilled Nursing Facility stays, or Medicare costs. These results suggest that targeted care management programs may provide dual-eligible beneficiaries with needed services while diverting inefficient health care utilization.

Outpatient Versus Inpatient Intravenous Antimicrobial Therapy: A Population-Based Observational Cohort Study of Adverse Events and Costs

BACKGROUND

Bacterial infections such as osteomyelitis and endocarditis routinely require several weeks of treatment with intravenous (IV) antimicrobials. Outpatient parenteral antimicrobial therapy (OPAT) programs allow patients to receive IV antimicrobials in an outpatient clinic or at home. The outcomes and costs of such treatments remain uncertain.

METHODS

We conducted a retrospective observational cohort study over a 5-year study interval (1 June 2012 to 31 March 2018) using population-based linked administrative data from British Columbia, Canada. Patients receiving OPAT following a hospitalization for bacterial infection were matched based on infection type and implied duration of IV antimicrobials to patients receiving inpatient parenteral antimicrobial therapy (IPAT). Cumulative adverse events and direct healthcare costs were estimated over a 90-day outcome interval.

RESULTS

In a matched cohort of 1842 patients, adverse events occurred in 35.6% of OPAT patients and 39.0% of IPAT patients (adjusted odds ratio, 1.04 [95% confidence interval {CI}, .83-1.30; P = .61). Relative to IPAT patients, OPAT patients were significantly more likely to experience hospital readmission (30.5% vs 23.0%) but significantly less likely to experience Clostridioides difficile diarrhea (1.2% vs 3.1%) or death (2.0% vs 8.8%). Estimated mean direct healthcare costs were $30 166 for OPAT patients and $50 038 for IPAT patients (cost ratio, 0.60; average cost savings with OPAT, $17 579 [95% CI, $14 131-$21 027]; P < .001).

CONCLUSIONS

Outpatient IV antimicrobial therapy is associated with a similar overall prevalence of adverse events and with substantial cost savings relative to patients remaining in hospital to complete IV antimicrobials. These findings should inform efforts to expand OPAT use.

Impact of new health care reform on enabling environment for children’s health in China: An interrupted time-series study

Background

Creating an enabling environment (EE) can help foster the development and health of children. The Chinese government implemented a new health care reform (NHR) in 2009 in a move to promote an EE for health. The purpose of this study was to evaluate the impact of the NHR on EE for children’s health.

Methods

An interrupted time-series analysis was used to evaluate the changes in the EE before and after 2009 in China. This study analysed the EE through five quantitative indicators, including policy element coverage rate (PECR), service meeting with children’s needs rate (SMCNR), multisector participation rate (MPR), and accountability mechanism clarity rate (AMCR), based on the content analysis of available public policy documents (updated as of 2019) from 31 provinces in mainland China, and the number of health care personnel of maternity and child care centres per 10 000 population (HP per 10 000 population), based on the 2002–2019 China Health Statistical Yearbook and China Statistical Yearbook.

Results

The average values of PECR, SMCNR, and MPR increased rapidly to 90.96%, 82.46%, and 81.31%, respectively, in 2019, representing a higher value compared to the AMCR (7.38%). The NHR promoted the EE, in which HP per 10 000 population showed the fastest increase (β₁ = 0.03, P < 0.01; β₃ = 0.10, P < 0.01), followed by SMCNR (β₁ = 0.94, P < 0.01; β₃ = 1.83, P < 0.01), AMCR (β₁ = 0.13, P < 0.01; β₃ = 0.24, P = 0.14), MPR (β₁ = 1.35, P < 0.01; β₃ = 2.47, P < 0.01) and PECR (β₁ = 1.43, P < 0.01; β₃ = 1.47, P < 0.01).

Conclusions

The NHR has a positive impact on the EE, especially on the human resources and service provision for children. Efforts should be intensified to improve the clarity of the accountability mechanism of the health-related sectors.

Exploring the question of financial incentives for training amongst non-adopters of MOUD in rural primary care

BACKGROUND

Medication for opioid use disorder (MOUD) includes administering medications such as buprenorphine or methadone, often with mental health services. MOUD has been shown to significantly improve outcomes and success of recovery from opioid use disorder. In WV, only 18% of providers including physicians, physician assistants, and nurse practitioners are waivered, and 44% of non-waivered providers were not interested in free training even if compensated. This exploratory research seeks to understand intervention-related stigma in community-based primary care providers in rural West Virginia, determine whether financial incentives for training may be linked to levels of stigma, and what level of financial incentives would be required for non-adopters of MOUD services provision to obtain training.

METHOD

Survey questions were included in the West Virginia Practice-Based Research Network (WVPBRN) annual Collective Outreach & Research Engagement (CORE) Survey and delivered electronically to each practice site in WV. General demographic, staff attitudes and views on compensation for immersion training for delivering MOUD therapy in primary care offices were returned. Statistical analysis included logistic and multinomial logistic regression and an independent samples t-test.

RESULTS

Data were collected from 102 participants. Perceived stigma did significantly predict having a waiver with every 1-unit increase in stigma being associated with a 65% decreased odds of possessing a waiver for buprenorphine/MOUD (OR = 0.35; 95% CI  0.16-0.78, p = 0.01). Further, t-test analyses suggested there was a statistically significant mean difference in perceived stigma (t(100) = 2.78, p = 0.006) with those possessing a waiver (M = 1.56; SD = 0.51) having a significantly lower perceived stigma than those without a waiver (M = 1.92; SD = 0.57). There was no statistically significant association of stigma on whether someone with a waiver actually prescribed MOUD or not (OR = 0.28; 95% CI  0.04-2.27, p = 0.234).

CONCLUSION

This survey of rural primary care providers demonstrates that stigmatizing beliefs related to MOUD impact the desired financial incentive to complete a one-day immersion, and that currently unwaivered providers endorse more stigmatizing beliefs about MOUD when compared to currently waivered providers. Furthermore, providers who endorse stigmatizing beliefs with respect to MOUD require higher levels of compensation to consider such training.
