Usability of Hospital Price Estimators for Lumbar Spine MRI

PurposeThe aim of this study was to evaluate the usability of online hospital price estimators for a common imaging examination using surrogate patients.MethodsUsing the Amazon Mechanical Turk platform, the authors recruited adult English-speaking US residents as surrogate patients to find the cash price for a noncontrast lumbar spine MRI examination for a self-pay patient using price estimator tools at four hospitals. All were asked to view a 3-min tutorial video and report their experiences with the task, including the System Usability Scale (SUS) for the estimator, through a paid survey. Participants were queried about demographics, insurance, prior imaging exposure, and assessed health literacy and health insurance literacy using validated measures. Multivariable analysis for correct price identification and price estimator SUS were performed.ResultsOf 660 respondents, 476 met eligibility criteria (72.7% <45 years of age, 41.7% female, 86.1% white); 76.9% found all four estimators, and 9.2% were unable to locate any. Only 27.7% found the correct price at all four hospitals, with 67.4% being able to find at least one correct cash price. Average SUS score for the hospitals’ estimators ranged between 62.4 and 77.5. The hospital with a similar estimator to that used in the tutorial video had the highest SUS score. Accuracy of price identification improved with later tasks. Higher health insurance literacy was associated with higher identification of at least one correct price (odds ratio, 1.21; 95% confidence interval, 1.02-1.44) and higher SUS score (B = 1.68; 95% confidence interval, 1.07-2.29).ConclusionsSurrogate patients were able to locate hospital price estimators but unable to effectively use them to obtain correct prices. Tutorial videos improved SUS score, but correct price identification improved with practice.     

Physician complicity in human rights violations: Involuntary sterilization among women from Mexico and Central America seeking asylum in the United States

Involuntary sterilization is a violation of human rights and grounds for asylum in the United States. Forensic medical evaluations can be useful in documenting this form of persecution and supporting asylees’ claims for immigration relief. We conducted a retrospective case analysis of the personal and medical affidavits of 14 asylum-seeking women from four Latin America countries who all reported they had been involuntarily sterilized. Sixty-four percent said that “consent” was coerced; the remainder were unaware of having been sterilized at the time of the procedure. In all cases, findings on hysterosalpingogram were consistent with sterilization, revealing that all 14 had undergone a tubal ligation. Eighty-six percent of the women had been sterilized at the time of childbirth. The healthcare providers involved in the 14 cases failed to obtain informed consent, misled patients about sterilization, engaged in discriminatory behavior, and/or breached patient confidentiality regarding their HIV-status. All 14 asylum cases were defensive; of the 7 cases (50%) that have been decided to date, 100% have been granted asylum.     

Feasibility and Timing of Prehospital Administration of Reteplase in Patients with Acute Myocardial Infarction

Background: In myocardial infarction patients undergoing thrombolysis, treatment delays negatively impact outcomes. This pilot study was conducted to determine the feasibility and timing of field administration of intravenous double bolus reteplase in patients with ST-elevation myocardial infarction. Methods: Sixty three patients with symptoms and EKG changes consistent with acute myocardial infarction of less than six hours duration received the first bolus of reteplase before arriving at the emergency department. A second bolus of reteplase was given in the emergency department. Subsequent resolution of ST-segment elevation was measured. Mean time from symptom onset to paramedic dispatch, and paramedic arrivals to first bolus of reteplase were measured. The mean time from the first bolus of reteplase to heparin bolus in an emergency department was also measured. All patients with evidence of ST-elevation and suspected acute myocardial infarction gave consent for the thrombolytic therapy. There were no refusals of therapy among those candidates eligible for thrombolysis. Results: The mean times from the first bolus of reteplase to heparin bolus in the emergency department was substantially longer than the in-field times. Resolution of ST-segment elevation was recorded in 52 of the 63 patients and the times of resolution ranged from five minutes after the first bolus dose to 190 minutes after the second bolus of reteplase. Resolution of ST-segment elevation and relief of pain occurred almost simultaneously. Conclusions: These results demonstrated that in-field administration of thrombolytic therapy is a viable option to reduce the delay from symptom onset to initiation of thrombolysis. They demonstrated that satisfactory resolution of ST-segment elevation can be recorded in the field. The reduction in mortality observed in this study is comparable to previously published studies on inpatients. Abbreviated Abstract. This open-label pilot study was conducted to determine the feasibility and timing of field administration of intravenous double-bolus reteplase and to measure subsequent resolution of ST elevation in 63 patients with symptoms and ECG changes consistent with acute myocardial infarction for less than 6 hours. These results demonstrated that in-field administration of thrombolytic therapy is a viable option to reduce the delay from symptom onset to initiation of thrombolytic therapy.     

Lipoprotein(a) and aortic valve stenosis: A casual or causal association?

AimsThis review aims to provide an update of available methods for imaging calcification activity and potential therapeutic options.Data SynthesisAortic valve calcification represents the most common heart valve condition requiring treatment among adults in Western societies. No medical therapies are proven to be effective in treating symptoms or reducing disease progression. Therefore, surgical or transcatheter aortic valve replacement remains the only available treatment option. Elevated circulating concentrations of lipoprotein(a) is strongly associated with degenerative aortic stenosis. This relationship was first observed in prospective observational studies, and the causal relationship was confirmed in genetic studies.ConclusionsNew therapeutic targets have been identified and new imaging techniques could be used to test the effectiveness of new agents and further clarify the pathophysiology of AVS. No therapy that specifically lowers Lp (a) levels has been approved for clinical use.

Patient preferences

Objective: To assess whether patients can weigh risk comparisons involving mortality and quality of life in an understandable manner based on their willingness to accept risks of complications. Design: Cross-sectional survey of patients. Setting: University-based Department of Veterans Affairs Medical Center. Participants: 230 men patients seen in a general medicine clinic. Measurements: Two survival graphs were used. Each graph contained survival curves for two alternative unidentified treatments for an unidentified medical condition. Graph 2 contained one curve that had a life expectancy that was 14% higher than the life expectancy of the corresponding curve in graph 1. Respondents were randomly assigned one of the two graphs and were asked to indicate which treatment they preferred and what risk of a change in their quality of life (urinary incontinence or impotence) they were willing to accept to achieve longer survival. Patients were also asked whether they had a history of urinary incontinence or impotence. Results and conclusions: Patients tended to be unwilling to accept worse quality of life to achieve increased survival over time. For both curve comparisons, significantly more (p<0.01) patients accepted a treatment associated with higher mortality to avoid a 100% chance of incontinence than to avoid a 100% chance of impotence. Of the 75% (172/230) of patients reporting willingness to accept risk of either urinary incontinence or total impotence or both, 62% reported having at least some symptoms related to urinary incontinence or impotence. Of the 58 patients not willing to accept the complication risks, only 11% reported a history of urinary incontinence or impotence. The results show that patients are able to make distinctions about severity of morbidity, men are less willing to accept the risk of urinary incontinence than that of total impotence, and men patients who are symptomatic with urinary incontinence or impotence are more willing to accept the risks of treatment than are asymptomatic patients.

Comparison of costs of percutaneous transluminal coronary angioplasty and coronary bypass surgery for patients with angina pectoris

To determine the costs of a procedure, the total costs of the department that provides the service must be considered and, in addition, the direct cost of the specific procedure. Applying this principle to the cost accounting of angioplasty and bypass surgery results in a direct, i.e. procedural, cost, including the initial hospital stay, of respectively 8694 Dfl and 20,987 Dfl. A review of the follow-up data for the first year after the original intervention revealed a 2% reintervention rate for bypass surgery, while this percentage was 29% for angioplasty. Adding the first year costs involved with reinterventions to the procedural costs results in a 1-year cost of angioplasty and bypass operation of 13,625 Dfl and 21,363 Dfl, respectively. It is concluded that because of reinterventions in the first year, a mark up of 57% on the procedural cost of angioplasty must be added to cover 1-year costs, while for bypass surgery this is only 1%. Nevertheless, the 1-year cost for angioplasty is still 36% less than for bypass surgery. As reinterventions after PTCA may stay considerably higher than for CABG for several years, the mark-up percentages will be substantially higher for longer time spans. This may tend to equalize the total costs of PTCA and CABG over time spans of perhaps 5-8 years. Sufficient data are not available to verify this statement. Clinicians must realize that choosing the most appropriate procedure is not only a matter of medical assessment but also a matter of cost effectiveness. CABG can be seen as an 'investment decision' while PTCA tends to become a decision with characteristics of 'maintenance planning'!     

Using an office system intervention to increase breast cancer screening

OBJECTIVE: To evaluate an innovative approach to continuing medical education, an outreach intervention designed to improve performance rates of breast cancer screening through implementation of office systems in community primary care practices. DESIGN: Randomized, controlled trial with primary care practices assigned to either the intervention group or control group, with the practice as the unit of analysis. SETTING: Twenty mostly rural counties in North Carolina. PARTICIPANTS: Physicians and staff of 62 randomly selected family medicine and general internal medicine practices, primarily fee-for-service, half group practices and half solo practitioners. INTERVENTION: Physician investigators and facilitators met with practice physicians and staff over a period of 12 to 18 months to provide feedback on breast cancer screening performance, and to assist these primary care practices in developing office systems tailored to increase breast cancer screening. MEASUREMENTS AND MAIN RESULTS: Physician questionnaires were obtained at baseline and follow-up to assess the presence of five indicators of an office system. Three of the five indicators of office systems increased significantly more in intervention practices than in control practices, but the mean number of indicators in intervention practices at follow-up was only 2.8 out of 5. Cross-sectional reviews of randomly chosen medical records of eligible women patients aged 50 years and over were done at baseline (n=2,887) and follow-up (n=2,874) to determine whether clinical breast examinations and mammography, were performed. Results for mammography were recorded in two ways, mention of the test in the visit note and actual report of the test in the medical record. These reviews showed an increase from 39% to 51% in mention of mammography in intervention practices, compared with an increase from 41% to 44% in control practices (p=.01). There was no significant difference, however, between the two groups in change in mammograms reported (intervention group increased from 28% to 32.7%; control group increased from 30.6% to 34.0%, p=.56). There was a nonsignificant trend (p=.06) toward a greater increase in performance of clinical breast examination in intervention versus control practices. CONCLUSIONS: A moderately intensive outreach intervention to increase rates of breast cancer screening through the development of office systems was modestly successful in increasing indicators of office systems and in documenting mention of mammography, but had little impact on actual performance of breast cancer screening. At follow-up, few practices had a complete office system for breast cancer screening. Outreach approaches to assist primary care practices implement office systems are promising but need further development.
