The surgery literature is filled with reports on racial or gender disparities in quality. However, whether patient demographics are risk factors for complications or death from ambulatory surgical procedures is unknown. This study explores whether racial, age, and gender outcome disparities exist after ambulatory surgeries. Patients studied included adults (>18 years) receiving common ambulatory surgical procedures (N = 3 174 436) in either a freestanding ambulatory surgical center or a hospital-based outpatient department during 1997-2004 in Florida. Results demonstrate that African Americans were at a significantly increased risk for either mortality or unexpected hospitalization in 4 of the 5 procedures examined, even after controlling for confounders. For women, unexpected hospital admission or mortality was less likely to occur after almost all procedures examined. Thus, many of the racial and gender disparities in the inpatient surgical literature are also observed in the ambulatory setting. More research is needed to determine the source of these disparities.

Hospital—physician relationships (HPRs) are a key concern for both parties. Hospital interest has been driven historically by the desire for the physician's clinical business, the need to combat managed care, and now the threats posed by single specialty hospitals, medical device vendors, and consumerism. Physician interest has been driven by fears of managed care and desires for new sources of revenue. The dyadic relationships between hospitals and physicians are thus motivated and influenced by the role of third parties. This article analyzes the history of HPRs and the succession of third parties. The analysis illustrates that the role of third parties has shifted from a unifying one to one that divides hospitals and physicians. This shift presents both opportunities and problems.

Lower extremity amputation (LEA) is a serious complication of diabetes. We sought to determine whether quality of ambulatory care affects risk of LEA. We conducted a claims-based case-control study of 409 Medicare beneficiaries younger than age 75 with diabetes and LEA between January 1, 2003, and December 31, 2005. They were matched with controls with diabetes without LEA, on age, gender, number of diabetes outpatient visits, and (for those with hospital admissions between January 1, 2000, and December 31, 2002) number of comorbid conditions, diabetes complications, and peripheral vascular disease. Quality-of-care measures for cases and controls covered the period April 1, 1999, through March 31, 2001. LEA patients were less likely to have had lipid screening than controls (odds ratio = 0.73; 95% confidence interval = 0.53-0.99), and controls were more likely to use physicians with high performance in lipid screening (χ ² = 6.631, P = .012) and hemoglobin A1c testing (χ ² = 6.079, P = .014).

Rural and small community hospitals typically have few resources and little experience with quality improvement (QI) and, on average, demonstrate poorer quality of care than larger facilities. Formalized QI education shows promise in improving quality, but little is known about its effect in rural and small community hospitals. The authors describe a randomized controlled trial assigning 47 rural and small community Texas hospitals to such a program (n = 23) or to the control group (n = 24), following provision of a Web-based quality benchmarking and case review tool. Centers for Medicare and Medicaid Services Core Measures composite scores for congestive heart failure (CHF) and community-acquired pneumonia (CAP), using Texas Medical Foundation data collected via the QualityNet Exchange system, are compared for the groups, for 2 years postintervention. Given the estimated baseline rates for the CHF (68%) and CAP (66%) composites, the cohort enables the detection of 14% and 11% differences (α = .05; power = 0.8), respectively.

Background. Few studies have investigated the time it takes physicians to follow up abnormal outpatient laboratory results. Methods. Medical record review of all adult patients seen at a primary care practice between January 2002 and December 2005 with serum potassium results ≥ 6.0 mEq/L. We used a proportional hazards model to assess factors associated with time to follow-up for episodes of hyperkalemia. Results. 259 of 48 333 serum potassium results met inclusion criteria. The median follow-up time was 3 days; after 30 days, 10% of cases had no follow-up. Residing in the same zip code as the clinic (HR = 1.39; P = .029), degree of hyperkalemia (HR = 2.97; P < .001), and renal insufficiency (HR = 1.41; P = .015) were associated with decreased time to repeat testing. Conversely, African Americans (HR = .51; P = .007) had increased time to repeat testing. Conclusions. Follow-up of abnormal laboratory results in outpatients is suboptimal and research is needed to better understand factors that delay follow-up. (Am J Med Qual 2007;22:428-437)

The Veterans Health Administration (VHA) has achieved considerable success in improving health care through the use of clinical performance measures. This report examines the self-reported strategies used by the most successful facilities in the VHA system. For fiscal year 2002, facilities that scored the highest on any of 24 clinical performance measures were queried as to which strategies they used to achieve their level of performance. The most commonly cited strategies across all performance categories were organizational change (55.6%), clinical reminders (41.4%), audit and feedback to providers (39.6%), and staff education (32.5%). Certain strategies were more likely to be cited for 1 or more specific performance categories (eg, clinical reminders for immunization [61.1%], screening [60.6%]). These findings suggest that successful facilities are generally using evidence-based strategies to achieve high clinical performance. However, some evidence-based implementation strategies were rarely cited (eg, use of clinical champions). (Am J Med Qual 2007;22: 438-444)

Treatment nonadherence is a recognized problem, but most practice settings use education alone to address it. Psychological counseling methods generate greater behavior change but are not widely used. Telehealth nursing can be used to integrate these methods into routine clinical practice. This study was a nonrandomized trial of a telehealth program that used motivational interviewing and cognitive— behavioral techniques to improve osteoporosis medication adherence. Registered nurses delivered the intervention to 402 participants recruited from provider offices across the United States. Initial participation rates were high in this community-based sample, although attrition also was high. Six-month adherence based on pharmacy and clinical interview data was significantly higher than the general population rate. A comparison with nonparticipants approached significance, and there was a significant dose—response effect. Most reasons given for nonadherence were psychological. The results support the use of psychological techniques to improve adherence and the use of telehealth to disseminate evidence-based patient counseling. (Am J Med Qual 2007;22 445-456)

Rates of adherence to an acute pharyngitis practice guideline in the retail clinic setting were measured as an indicator of clinical quality. An analysis of 57 331 patient visits for the evaluation of acute pharyngitis was conducted. In 39 530 patients with a negative rapid strep test result, nurse practitioner and physician assistant staff adhered to guidelines in 99.05% of cases by withholding unnecessary antibiotics. Of 13 471 patients with a positive rapid strep test result, 99.75% received an appropriate antibiotic prescription. The combined guideline adherence rate for groups with positive and negative rapid strep test results was 99.15%. Strep cultures were performed on 99.1% of patients with a negative rapid strep test result, and 96.2% of patients with a positive culture were treated with an antibiotic. Finally, 0.95% of patients with a negative rapid strep test result were provided an antibiotic outside clinical guidelines; however, approximately half of these prescriptions (n = 190) were supported by documentation of clinical concerns for which an antibiotic was a reasonable choice.
