Urologist practice structure and quality of prostate cancer care.
Ontology highlight
ABSTRACT: Objective
To examine three aspects of urologist practice structure that may affect quality of prostate cancer care: practice size, ownership of an intensity modulated radiation therapy (IMRT) device, participation within a multi-specialty group (MSG). Health care reforms focused on improving quality are particularly relevant for prostate cancer given its prevalence and concerns for overdiagnosis and overtreatment.Methods
Using data from the Surveillance, Epidemiology and End-Results (SEER)-Medicare linked registry, we examined quality of prostate cancer treatment according to each treating urologist's practice size, type (single-specialty vs. MSG) and ownership of IMRT. Mixed models were used to adjust for patient differences.Results
We identified 22,412 men with newly diagnosed prostate cancer treated by 2,199 urologists during the study. We observed minimal differences for most quality metrics according to practice size, type, and ownership of IMRT. Adherence to all eligible quality metrics was better among MSGs compared to single specialty groups (20.0% adherence versus 18.2%, p=0.01) whereas there was no significant difference by ownership of IMRT (17.1% adherence in owners versus 18.9% non-owners, p=0.09).Conclusion
Differences in quality across practice size, type and ownership of IMRT were modest, with substantial room for improvement regardless of practice structure.

Project description:BACKGROUND:Prostate cancer treatment is a significant source of morbidity and spending. Some men with prostate cancer, particularly those with significant health problems, are unlikely to benefit from treatment. OBJECTIVE:To assess relationships between financial incentives associated with urologist ownership of radiation facilities and treatment for prostate cancer. DESIGN, SETTING, AND PARTICIPANTS:A retrospective cohort of Medicare beneficiaries with prostate cancer diagnosed between 2010 and 2012. Patients were further classified by their risk of dying from noncancer causes in the 10 yr following their cancer diagnosis by using a mortality model derived from comparable patients known to be cancer-free. INTERVENTION:Urologists were categorized by their practice affiliation (single-specialty groups by size, multispecialty group) and ownership of a radiation facility. OUTCOME MEASUREMENTS AND ANALYSIS:Use of intensity-modulated radiation therapy (IMRT) and use of any treatment within 1 yr of diagnosis. Generalized estimating equations were used to adjust for patient differences. RESULTS:Among men with newly diagnosed prostate cancer, use of IMRT ranged from 24% in multispecialty groups to 37% in large urology groups (p<0.001). Patients managed in groups with IMRT ownership (n=5133) were more likely to receive IMRT than those managed by single-specialty groups without ownership (43% vs 30%, p<0.001), regardless of group size. Among patients with a very high risk (> 75%) of noncancer mortality within 10 yr of diagnosis, both IMRT use (42% vs 26%, p<0.001) and overall treatment (53% vs 44%, p<0.001) were more likely in groups with ownership than in those without, respectively. CONCLUSIONS:Urologists practicing in single-specialty groups with an ownership interest in radiation therapy are more likely to treat men with prostate cancer, including those with a high risk of noncancer mortality. PATIENT SUMMARY:We assessed treatment for prostate cancer among urologists with varying levels of financial incentives favoring intervention. Those with stronger incentives, as determined by ownership interest in a radiation facility, were more likely to treat prostate cancer, even when treatment was unlikely to provide a survival benefit to the patient.

Project description:Because insurers use performance and quality metrics to inform reimbursement, identifying remediable causes of poor-quality cancer care is imperative. We undertook this descriptive cohort study to assess key predictors of women's perceived quality of their breast cancer care and actual guideline-concordant quality of care received.We surveyed inner-city women with newly diagnosed and surgically treated early-stage breast cancer requiring adjuvant treatment who were enrolled onto a randomized controlled trial (RCT) of patient assistance to reduce disparities in care. We assessed women's perceived quality of care and perceived quality of the process of getting care, such as getting referrals, test results, and treatments; we abstracted records to determine the actual quality of care.Of the 374 new patients with early-stage breast cancer enrolled onto the RCT, only a slight majority of women (55%) perceived their quality of care as excellent; 88% actually received good-quality, guideline-concordant care. Excellent perceived quality (P < .001) was significantly associated with patients' perception of the quality of the process of getting care (adjusted relative risk [RR], 1.78; 95% CI, 1.65 to 1.87). Also associated with perceived quality-and mediated by race-were trust in one's physician (adjusted RR, 1.43; 95% CI, 1.16 to 1.64) and perceived racism, which affected black women more than women of other races/ethnicities (black race-adjusted RR for perceived racism, 0.33 [95% CI, 0.10 to 0.87]; black race-adjusted RR for trust, 1.61 [95% CI, 0.97 to 1.90]; c = 0.82 for the model; P < .001). Actual quality of care provided did not affect perceived quality of care received.Patients' perceived quality of care differs from their receipt of high-quality care. Mutable targets to improve perceived quality of care include the processes of getting care and trusting their physician.

Project description:PURPOSE:Despite the endorsement of several quality measures for prostate cancer by the National Quality Forum and the Physician Consortium for Performance Improvement, how consistently physicians adhere to these measures has not been examined. We evaluated regional variation in adherence to these quality measures to identify targets for future quality improvement. MATERIALS AND METHODS:For this retrospective cohort study we used SEER (Surveillance, Epidemiology, and End Results)-Medicare data for 2001 to 2007 to identify 53,614 patients with newly diagnosed prostate cancer. Patients were assigned to 661 regions (Hospital Service Areas). Hierarchical generalized linear models were used to examine reliability adjusted regional adherence to the endorsed quality measures. RESULTS:Adherence at the patient level was highly variable, ranging from 33% for treatment by a high volume provider to 76% for receipt of adjuvant androgen deprivation therapy while undergoing radiotherapy for high risk cancer. In addition, there was considerable regional variation in adherence to several measures, including pretreatment counseling by a urologist and radiation oncologist (range 9% to 89%, p <0.001), avoiding overuse of bone scans in low risk cancer (range 16% to 96%, p <0.001), treatment by a high volume provider (range 1% to 90%, p <0.001) and followup with radiation oncologists (range 14% to 86%, p <0.001). CONCLUSIONS:We found low adherence rates for most established prostate cancer quality of care measures. Within most measures regional variation in adherence was pronounced. Measures with low adherence and a large amount of regional variation may be important low hanging targets for quality improvement.

Project description:ContextFinancial and demographic pressures in US require an understanding of the most efficient distribution of physicians to maximize population-level health benefits. Prior work has assumed a constant negative relationship between physician supply and mortality outcomes throughout the US and has not addressed regional variation.MethodsIn this ecological analysis, geographically weighted regression was used to identify spatially varying relationships between local urologist density and prostate cancer mortality at the county level. Data from 1,492 counties in 30 eastern and southern states from 2006-2010 were analyzed.FindingsThe ordinary least squares (OLS) regression found that, on average, increasing urologist density by 1 urologist per 100,000 people resulted in an expected decrease in prostate cancer mortality of -0.499 deaths per 100,000 men (95% CI -0.709 to -0.289, p-value < 0.001), or a 1.5% decrease. Geographic weighted regression demonstrated that the addition of one urologist per 100,000 people in counties in the southern Mississippi River states of Arkansas, Mississippi, and Louisiana, as well as parts of Illinois, Indiana, and Wisconsin is associated with decrease of 0.411 to 0.916 in prostate cancer mortality per 100,000 men (1.6-3.6%). In contrast, the urologist density was not significantly associated with the prostate state mortality in the new England region.ConclusionsThe strength of association between urologist density and prostate cancer mortality varied regionally. Those areas with the highest potential for effects could be targeted for increasing the supply of urologists, as it associated with the largest predicted improvement in prostate cancer mortality.

Project description:Patients who receive surgery from high-volume surgeons tend to have better outcomes. Black patients, however, are less likely to receive surgery from high-volume surgeons.Among men with localized prostate cancer, we examined whether disparities in use of high-volume urologists resulted from racial differences in patients being diagnosed by high-volume urologists and/or changing to high-volume urologists for surgery.Retrospective cohort study from Surveillance, Epidemiology, and End Results-Medicare data.A total of 26,058 black and white men in Surveillance, Epidemiology, and End Results-Medicare diagnosed with localized prostate cancer from 1995 to 2005 that underwent prostatectomy. Patients were linked to their diagnosing urologist and a treating urologist (who performed the surgery).Diagnosis and receipt of prostatectomy by a high-volume urologist, and changing between diagnosing and treating urologistAfter adjustment for confounders, black men were as likely as white men to be diagnosed by a high-volume urologist; however, they were significantly less likely than white men to be treated by a high-volume urologist [odds ratio 0.76; 95% confidence interval (CI), 0.67-0.87]. For men diagnosed by a low-volume urologist, 46.0% changed urologists for their surgery. Black men were significantly less likely to change to a high-volume urologist (relative risk ratio 0.61; 95% CI, 0.47-0.79). Racial differences appeared to reflect black and white patients being diagnosed by different urologists and having different rates of changing after being diagnosed by the same urologists.Lower rates of changing to high-volume urologists for surgery among black men contribute to racial disparities in treatment by high-volume surgeons.

Project description:PurposeOverlooking other medical conditions during cancer treatment and follow-up could result in excess morbidity and mortality, thereby undermining gains associated with early detection and improved treatment of cancer. We compared the quality of care for diabetes patients subsequently diagnosed with breast, colorectal, or prostate cancer to matched, diabetic non-cancer controls.MethodsLongitudinal cohort study using primary care records from the Clinical Practice Research Datalink, United Kingdom. Patients with pre-existing diabetes were followed for up to 5 years after cancer diagnosis, or after an assigned index date (non-cancer controls). Quality of diabetes care was estimated based on Quality and Outcomes Framework indicators. Mixed effects logistic regression analyses were used to compare the unadjusted and adjusted odds of meeting quality measures between cancer patients and controls, overall and stratified by type of cancer.Results3382 cancer patients and 11,135 controls contributed 44,507 person-years of follow-up. In adjusted analyses, cancer patients were less likely to meet five of 14 quality measures, including: total cholesterol ≤ 5 mmol/L (odds ratio [OR] = 0.82; 95% confidence interval [CI], 0.75-0.90); glycosylated hemoglobin ≤ 59 mmol/mol (adjusted OR = 0.77; 95% CI, 0.70-0.85); and albumin creatinine ratio testing (adjusted OR = 0.83; 95% CI, 0.75-0.91). However, cancer patients were as likely as their matched controls to meet quality measures for other diabetes services, including retinal screening, foot examination, and dietary review.ConclusionsAlthough in the short-term, cancer patients were less likely to achieve target thresholds for cholesterol and HbA1c, they continued to receive high-quality diabetes primary care throughout 5 years post diagnosis.Implications for cancer survivorsThese findings are important for cancer survivors with pre-existing diabetes because they indicate that high-quality diabetes care is maintained throughout the continuum of cancer diagnosis, treatment, and follow-up.

Project description:Difference in the quality of care may contribute to the less optimal prostate cancer treatment outcomes among black men compared with white men. We determined whether a racial quality of care gap exists in surgical care for prostate cancer, as evidenced by racial variation in the use of high volume surgeons and facilities, and in the quality of certain outcome measures of care.We performed cross-sectional and cohort analyses of administrative data from the Healthcare Cost and Utilization Project all-payer State Inpatient Databases, encompassing all nonfederal hospitals in Florida, Maryland and New York State from 1996 to 2007. Included in analysis were men 18 years old or older with a diagnosis of prostate cancer who underwent radical prostatectomy. We compared the use of surgeons and/or hospitals in the top quartile of annual volume for this procedure, inpatient blood transfusion, complications, mortality and length of stay between black and white patients.Of 105,972 patients 81,112 (76.5%) were white, 14,006 (13.2%) were black, 6,999 (6.6%) were Hispanic and 3,855 (3.6%) were all other. In mixed effects multivariate models, black men had markedly lower use of high volume hospitals (OR 0.73, 95% CI 0.70-0.76) and surgeons (OR 0.67, 95% CI 0.64-0.70) compared to white men. Black men also had higher odds of blood transfusion (OR 1.08, 95% CI 1.01-1.14), longer length of stay (OR 1.07, 95% CI 1.06-1.07) and inpatient mortality (OR 1.73, 95% CI 1.02-2.92).Using an all-payer data set, we identified concerning potential quality of care gaps between black and white men undergoing radical prostatectomy for prostate cancer.

Project description:We expanded the clinical usefulness of EPIC-CP (Expanded Prostate Cancer Index Composite for Clinical Practice) by evaluating its responsiveness to health related quality of life changes, defining the minimally important differences for an individual patient change in each domain and applying it to a sexual outcome prediction model.In 1,201 subjects from a previously described multicenter longitudinal cohort we modeled the EPIC-CP domain scores of each treatment group before treatment, and at short-term and long-term followup. We considered a posttreatment domain score change from pretreatment of 0.5 SD or greater clinically significant and p ? 0.01 statistically significant. We determined the domain minimally important differences using the pooled 0.5 SD of the 2, 6, 12 and 24-month posttreatment changes from pretreatment values. We then recalibrated an EPIC-CP based nomogram model predicting 2-year post-prostatectomy functional erection from that developed using EPIC-26.For each health related quality of life domain EPIC-CP was sensitive to similar posttreatment health related quality of life changes with time, as was observed using EPIC-26. The EPIC-CP minimally important differences in changes in the urinary incontinence, urinary irritation/obstruction, bowel, sexual and vitality/hormonal domains were 1.0, 1.3, 1.2, 1.6 and 1.0, respectively. The EPIC-CP based sexual prediction model performed well (AUC 0.76). It showed robust agreement with its EPIC-26 based counterpart with 10% or less predicted probability differences between models in 95% of individuals and a mean ± SD difference of 0.0 ± 0.05 across all individuals.EPIC-CP is responsive to health related quality of life changes during convalescence and it can be used to predict 2-year post-prostatectomy sexual outcomes. It can facilitate shared medical decision making and patient centered care.

Project description:BACKGROUND: Although we are observing a general move towards larger primary care practices, surprisingly little is known about the influence of key components of practice organization on primary care. We aimed to determine the relationships between practice size, and revenue sharing agreements, and quality of care. METHODS: As part of a large cross sectional study, group practices were randomly selected from different primary care service delivery models in Ontario. Patient surveys and chart reviews were used to assess quality of care. Multilevel regressions controlled for patient, provider and practice characteristics. RESULTS: Positive statistically significant associations were found between the logarithm of group size and access, comprehensiveness, and disease prevention. Negative significant associations were found between logarithm group size and continuity. No differences were found for chronic disease management and health promotion. Practices that shared revenues were found to deliver superior health promotion compared to those who did not. Interacting group size with the presence of a revenue-sharing arrangement had a negative impact on health promotion. CONCLUSIONS: Despite the limitations of our study, our findings have provided preliminary evidence of the tradeoffs inherent with increasing practice size. Larger group size is associated with better access and comprehensiveness but worse continuity of care. Revenue sharing in group practices was associated with higher health promotion compared to sharing only common costs. Further work is required to better inform policy makers and practitioners as to whether the pattern revealed in larger practices mitigates any of the previously reported benefits of continuity of primary care. We found few benefits of revenue sharing--even then the effect of revenue sharing on health promotion seemed diminished in larger practices.

Project description:BackgroundPatients with osteoporosis can sustain fractures following falls or other minimal trauma. This risk of fracture can be reduced through appropriate diagnostic testing, pharmacologic therapy, and other readily measured standards of care.ObjectivesOur aim was to develop a credible clinical performance assessment to measure physicians' quality of osteoporosis care, and determine reasonable performance standards for both competent and excellent care.DesignThis was a retrospective cohort study.ParticipantsThree hundred and eighty one general internists and subspecialists with time-limited board certification were included in the study.Main measuresPerformance rates on eight evidence-based measures were obtained from the American Board of Internal Medicine (ABIM) Osteoporosis Practice Improvement Module® (PIM), a web-based tool that uses medical chart reviews to help physicians assess and improve care. We applied a patented methodology, using an adaptation of the Angoff standard-setting method and the Dunn-Rankin method, with an expert panel skilled in osteoporosis care to form a composite and establish standards for both competent and excellent care. Physician and practice characteristics, including a practice infrastructure score based on the Physician Practice Connections Readiness Survey (PPC-RS), were used to examine the validity of the inferences made from the composite scores.Key resultsThe mean composite score was 67.54 out of 100 maximum points with a reliability of 0.92. The standard for competent care was 46.87, and for excellent care it was 83.58. Both standards had high classification accuracies (0.95). Sixteen percent of physicians performed below the competent care standard, while 22 % met the excellent care standard. Specialists scored higher than generalists, and better practice infrastructure was associated with higher composite scores, providing some validity evidence.ConclusionsWe developed a rigorous methodology for assessing physicians' osteoporosis care. Clinical performance feedback relative to absolute standards of care provides physicians with a meaningful approach to self-evaluation to improve patient care.
