The effect of a voucher incentive on a survey response rate in the clinical setting: a quasi-randomized controlled trial.

BACKGROUND: Financial rewards have been shown to be an important motivator to include normal healthy volunteers in trials. Less emphasis has been put on non-healthy volunteers. No previous study has investigated the impact of a voucher incentive for participants in a cross-sectional study in a clinical setting. The objective of this study was to examine the impact of a small voucher incentive on a survey response rate in a clinical setting at the point-of-care in a quasi-randomized controlled trial (q-RCT). METHODS: This was an ancillary study to a survey of patients subsequent to their appointment with a physician investigating physician-patient communication. We randomized participants to receive or not receive a voucher for a coffee (costs: 1 €) enclosed in the survey package. Alternation of groups was performed on a weekly basis. The exact Chi-square test was used to compare response rates between study arms. RESULTS: In total, 472 participants received the survey package. Among them, 249 participants were quasi-randomized to the voucher arm and 223 to the control group. The total response rate was 46%. The response rates were 48% in the voucher arm and 44% in the control group. The corresponding risk ratio was 1.09 (95% CI: 0.89, 1.32). CONCLUSIONS: A small voucher incentive to increase the response rate in a survey investigating physician-patient communication was unlikely to have an impact. It can be speculated whether the magnitude of the voucher was too low to generate an impact. This should be further investigated in future real-world studies.

Consequences of the 340B Drug Pricing Program.

BACKGROUND: The 340B Drug Pricing Program entitles qualifying hospitals to discounts on outpatient drugs, increasing the profitability of drug administration. By tying the program eligibility of hospitals to their Disproportionate Share Hospital (DSH) adjustment percentage, which reflects the proportion of hospitalized patients who are low-income, the program is intended to expand resources for underserved populations but provides no direct incentives for hospitals to use financial gains to enhance care for low-income patients. METHODS: We used Medicare claims and a regression-discontinuity design, taking advantage of the threshold for program eligibility among general acute care hospitals (DSH percentage, >11.75%), to isolate the effects of the program on hospital-physician consolidation (i.e., acquisition of physician practices or employment of physicians by hospitals) and on the outpatient administration of parenteral drugs by hospital-owned facilities in three specialties in which parenteral drugs are frequently used. For low-income patients, we also assessed the effects of the program on the provision of care by hospitals and on mortality. RESULTS: Hospital eligibility for the 340B Program was associated with 2.3 more hematologist-oncologists practicing in facilities owned by the hospital, or 230% more hematologist-oncologists than expected in the absence of the program (P=0.02), and with 0.9 (or 900%) more ophthalmologists per hospital (P=0.08) and 0.1 (or 33%) more rheumatologists per hospital (P=0.84). Program eligibility was associated with significantly higher numbers of parenteral drug claims billed by hospitals for Medicare patients in hematology-oncology (90% higher, P=0.001) and ophthalmology (177% higher, P=0.03) but not rheumatology (77% higher, P=0.12). Program eligibility was associated with lower proportions of low-income patients in hematology-oncology and ophthalmology and with no significant differences in hospital provision of safety-net or inpatient care for low-income groups or in mortality among low-income residents of the hospitals' local service areas. CONCLUSIONS: The 340B Program has been associated with hospital-physician consolidation in hematology-oncology and with more hospital-based administration of parenteral drugs in hematology-oncology and ophthalmology. Financial gains for hospitals have not been associated with clear evidence of expanded care or lower mortality among low-income patients.

Independent practice associations and physician-hospital organizations can improve care management for smaller practices.

Pay-for-performance, public reporting, and accountable care organization programs place pressures on physicians to use health information technology and organized care management processes to improve the care they provide. But physician practices that are not large may lack the resources and size to implement such processes. We used data from a unique national survey of 1,164 practices with fewer than twenty physicians to provide the first information available on the extent to which independent practice associations (IPAs) and physician-hospital organizations (PHOs) might make it possible for these smaller practices to share resources to improve care. Nearly a quarter of the practices participated in an IPA or a PHO that accounted for a significant proportion of their patients. On average, practices participating in these organizations provided nearly three times as many care management processes for patients with chronic conditions as nonparticipating practices did (10.4 versus 3.8). Half of these processes were provided only by IPAs or PHOs. These organizations may provide a way for small and medium-size practices to systematically improve care and participate in accountable care organizations.

Physician patient-sharing networks and the cost and intensity of care in US hospitals.

BACKGROUND: There is substantial variation in the cost and intensity of care delivered by US hospitals. We assessed how the structure of patient-sharing networks of physicians affiliated with hospitals might contribute to this variation. METHODS: We constructed hospital-based professional networks based on patient-sharing ties among 61,461 physicians affiliated with 528 hospitals in 51 hospital referral regions in the US using Medicare data on clinical encounters during 2006. We estimated linear regression models to assess the relationship between measures of hospital network structure and hospital measures of spending and care intensity in the last 2 years of life. RESULTS: The typical physician in an average-sized urban hospital was connected to 187 other doctors for every 100 Medicare patients shared with other doctors. For the average-sized urban hospital an increase of 1 standard deviation (SD) in the median number of connections per physician was associated with a 17.8% increase in total spending, in addition to 17.4% more hospital days, and 23.8% more physician visits (all P<0.001). In addition, higher "centrality" of primary care providers within these hospital networks was associated with 14.7% fewer medical specialist visits (P<0.001) and lower spending on imaging and tests (-9.2% and -12.9% for 1 SD increase in centrality, P<0.001). CONCLUSIONS: Hospital-based physician network structure has a significant relationship with an institution's care patterns for their patients. Hospitals with doctors who have higher numbers of connections have higher costs and more intensive care, and hospitals with primary care-centered networks have lower costs and care intensity.

Relationship between quality improvement processes and clinical performance.

OBJECTIVES: To examine the association between performance on clinical process measures and intermediate outcomes and the use of chronic care management processes (CMPs), electronic medical record (EMR) capabilities, and participation in external quality improvement (QI) initiatives. STUDY DESIGN: Cross-sectional analysis of linked 2006 clinical performance scores from the Integrated Healthcare Association's pay-for-performance program and survey data from the 2nd National Study of Physician Organizations among 108 California physician organizations (POs). METHODS: Controlling for differences in PO size, organization type (medical group or independent practice association), and Medicaid revenue, we used ordinary least squares regression analysis to examine the association between the use of CMPs, EMR capabilities, and external QI initiatives and performance on the following 3 clinical composite measures: diabetes management, processes of care, and intermediate outcomes (diabetes and cardiovascular). RESULTS: Greater use of CMPs was significantly associated with clinical performance: among POs using more than 5 CMPs, we observed a 3.2-point higher diabetes management score on a performance scale with scores ranging from 0 to 100 (P <.001), while for each 1.0-point increase on the CMP index, we observed a 1.0-point gain in intermediate outcomes (P <.001). Participation in external QI initiatives was positively associated with improved delivery of clinical processes of care: a 1.0-point increase on the QI index translated into a 1.4-point gain in processes-of-care performance (P = .02). No relationship was observed between EMR capabilities and performance. CONCLUSION: Greater investments in CMPs and QI interventions may help POs raise clinical performance and achieve success under performance-based accountability schemes.

Hospital-physician relations: two tracks and the decline of the voluntary medical staff model.

Data from the most recent Community Tracking Study (CTS) interviews in twelve nationally representative metropolitan areas indicate that hospitals are increasingly employing physicians, particularly specialists. Nonemployed physicians are separating from hospitals passively by refusing to serve on medical staff committees or take emergency department call, and actively by creating specialized facilities, such as ambulatory surgery centers (ASCs), to compete for hospitals' most profitable services. Employment is more common and physician-owned ASCs are less common in consolidated hospital markets. The interviews also suggest other factors motivating physician employment by, or separation from, hospitals, and likely consequences of these trends.

Emerging trends in Chinese healthcare: the impact of a rising middle class.

In this report, the authors examine a major phenomenon in the Chinese healthcare marketplace: the explosion of a vigorous and demanding middle class and its impact on the future directions the industry should pursue. Little is known about the expectations of the middle class regarding their healthcare needs other than through anecdotal or informal sources. The views of the middle class are shaped by a variety of influences which include exposure through direct personal contact with international healthcare facilities when traveling abroad or indirectly through increased exposure to the entertainment industry with its abundance of hospital and medical dramas. In addition to a general increased international awareness arising from more advanced education, the perspective of the middle class consumer is also shaped by the reality of what is currently available in China and what is realistic to expect. This report addresses this lack of factual data through an extensive survey of middle class consumers in three major cities in China: Beijing, Shanghai and Chengdu. The survey took a practical and pragmatic approach to exploring this issue. No attempt was made in this study to explain why the consumer feels the way they do about their healthcare expectations. The purpose was simply to outline what expectations the middle class have for the healthcare marketplace in China. In some respects the results are not surprising. They are the expectations that people have in any country, any where. They expect greater privacy and dignity in the care-giving process. They want to be more involved in the decisions that are made regarding their care. They would prefer a personal, private physician as opposed to a revolving door of faces they will never see a second time. They rely strongly on family and friends to advise them on their choice of provider. They expect clean, well-maintained facilities, efficient systems and courteous personnel. In other respects, the conclusions are not necessarily expected. They feel strongly that their hospital or provider of care should be located in a residential area. They are willing in some circumstances to pay more for their care in order to meet their expectations but not significantly more. Despite acknowledging that many of the facets of care they seek such as greater respect for privacy and a generally perceived more positive attitude in the care-giving process are found in foreign physicians, middle class consumers do not express a strong preference for foreign physicians but opt instead for Chinese physicians. In conclusion, the results provide an insight into the expectations held by middle class Chinese of their healthcare providers and outlines a direction for future healthcare development.
