Preoperative continuity of care and its relationship with cost of hepatopancreatic surgery

Continuity of Care and Healthcare Costs among Patients with Chronic Disease: Evidence from Primary Care Settings in China

Background:

Though critical to primary care, continuity of care has rarely been examined in China. This study aims to assess the relationship between continuity of care and healthcare costs among patients with chronic diseases within primary care settings in China.

Methods:

In this cross-sectional study, we used a social health insurance claims dataset of 1406 patients with hypertension and/or diabetes in Yuhuan City, Zhejiang Province collected in 2017–2019. We measured continuity of care using the Bice-Boxerman Continuity of Care (COC) Index, Herfindahl Index (HI), Sequential Continuity of Care (SECON) Index, Usual Provider of Care (UPC), and a binary variable indicating whether a patient’s UPC was a primary care provider. We examined the associations between continuity of care and healthcare costs in the same period and the subsequent year, using ordinary least squares regression for the outpatient costs and two-part regression for the inpatient costs. Based on the regression coefficients, we predicted costs saved if each continuity measure was set to 1 from the status quo.

Results:

When optimum continuity were to be achieved, 7.12–27.29% of total outpatient costs and 55.38–73.35% of total inpatient costs could be saved compared to the status quo during the two-year study period. If optimum continuity were to be achieved in the first year, 7.47%–21.78% of total outpatient costs and 8.84–40.22% of total inpatient costs could be saved in the second-year.

Conclusions:

Care continuity indicators were consistently associated with reduced outpatient costs and hospitalization risks. Future health reform in China should further enhance continuity of care in primary care.

Association between continuity of care (COC), healthcare use and costs: what can we learn from claims data? A rapid review

Objective

To describe how longitudinal continuity of care (COC) is measured using claims-based data and to review its association with healthcare use and costs.

Research design

Rapid review of the literature.

Methods

We searched Medline (PubMed), EMBASE and Cochrane Central, manually checked the references of included studies, and hand-searched websites for potentially additional eligible studies.

Results

We included 46 studies conducted in North America, East Asia and Europe, which used 14 COC indicators. Most reported studies (39/46) showed that higher COC was associated with lower healthcare use and costs. Most studies (37/46) adjusted for possible time bias and discussed causality between the outcomes and COC, or at least acknowledged the lack of it as a limitation.

Conclusions

Whereas a wide range of indicators is used to measure COC in claims-based data, associations between COC and healthcare use and costs were consistent, showing lower healthcare use and costs with higher COC. Results were observed in various population groups from multiple countries and settings. Further research is needed to make stronger causal claims.

Social vulnerability and fragmentation of postoperative surgical care among patients undergoing hepatopancreatic surgery

BACKGROUND

Regionalization of hepatopancreatic surgery to high-volume hospitals has been associated with fragmentation of postoperative care and, in turn, inferior outcomes after surgery. The objective of this study was to examine the association of social vulnerability with the likelihood of experiencing fragmentation of postoperative care (FPC) after hepatopancreatic surgery.

METHODS

Patients who underwent hepatopancreatic surgery and had at least 1 readmission within 90 days were identified using Medicare 100% Standard Analytical Files between 2013 and 2017. Fragmentation of postoperative care was defined as readmission at a hospital other than the index institution where the initial surgery was performed. The association of social vulnerability index and its components with fragmentation of postoperative care was examined.

RESULTS

Among 11,142 patients, 8,053 (72.3%) underwent pancreatectomy, and 3,089 (27.7%) underwent hepatectomy. The overall incidence of fragmentation of postoperative care was 32.9% (n = 3,667). Patients who experienced fragmentation of postoperative care were older (73 years [interquartile range: 69-77]_FPC vs 72 years [interquartile range: 68-77]_non-FPC) and had a higher Charlson comorbidity score (4 [interquartile range: 2-8]_FPC vs 3 [interquartile range: 2-8]_non-FPC) (both P < .001). Median overall social vulnerability index was higher among patients who experienced fragmentation of postoperative care (52.5 [interquartile range: 29.3-70.4]_FPC vs 51.3 [interquartile range: 27.9-69.4]_non-FPC, P = .02). On multivariable analysis, the odds of experiencing fragmentation of postoperative care was higher with increasing overall social vulnerability index (odds ratio: 1.14; 95% confidence interval 1.01-1.30). Additionally, the odds of experiencing fragmentation of postoperative care were higher among patients with high vulnerability owing to their socioeconomic status (odds ratio: 1.28; 95% confidence interval 1.12-1.45) or their household composition and disability (odds ratio: 1.35; 95% confidence interval 1.19-1.54), whereas high vulnerability owing to minority status and language was inversely associated with fragmentation of postoperative care (odds ratio: 0.73; 95% confidence interval 0.64-0.84).

CONCLUSION

Social vulnerability was strongly associated with the odds of experiencing fragmented postoperative care after hepatopancreatic surgery.

Impact of cancer center accreditation on outcomes of patients undergoing resection for hepatocellular carcinoma: A SEER-Medicare analysis

BACKGROUND

We sought to assess variations in outcomes among patients undergoing resection for hepatocellular carcinoma (HCC) at centers with varied accreditation status.

METHODS

Patients undergoing resection for HCC from 2004 to 2016 were identified from the linked SEER-Medicare database. Short- and long-term outcomes as well as expenditures associated with receipt of surgery were examined based on cancer center accreditation.

RESULTS

Among 1390 patients, 46.1% (n = 641) were treated at unaccredited centers, 39.3% (n = 546) at CoC-accredited and 14.6% (n = 203) at NCI-designated centers. Patients undergoing resection of HCC at NCI-designated hospitals had lower odds of complications (OR = 0.66, 95%CI: 0.45-0.98) and 90-day mortality (OR = 0.31, 95%CI: 0.11-0.85) after major liver resection compared with individuals treated at CoC-accredited centers. Receipt of surgery at NCI-designated hospitals (ref: CoC-accredited; HR = 0.81, 95%CI: 0.66-0.99) was an independent predictor of improved survival. Medicare payments for liver resection were comparable at different accreditation status centers (NCI: $21,760 vs CoC: $24,059 vs unaccredited: $24,724, p = 0.18).

CONCLUSION

Patients undergoing resection of HCC at NCI-designated hospitals had improved outcomes for the same level of Medicare expenditure compared with patients treated at CoC-accredited centers.
