Interdependence in decision-making by medical consultants: implications for improving the efficiency of inpatient physician services.

ABSTRACT: Hospital administrators are seeking to improve efficiency in medical consultation services, yet whether consultants make decisions to provide more or less care is unknown. We examined how medical consultants account for prior consultants' care when determining whether to provide intensive consulting care or sign off in the treatment of complex surgical inpatients. We applied three distinct theoretical frameworks in the interpretation of our results.We performed a retrospective cohort study of consultants' care intensity, measured alternately using a dummy variable for providing two or more days consulting (versus one) and a continuous measure of total days consulting, with 100% Medicare claims data from 2007-2010. Our analytic samples included consults for beneficiaries undergoing coronary artery bypass grafting (n = 61,785) or colectomy (n = 33,460) in general acute care hospitals. We compared the care intensity of consultants who observed different patterns of consulting care before their initial consults using ordinary least squares regression models at the patient-physician dyad level, controlling for patient comorbidity and many other patient- and physician-level factors as well as hospital region and year fixed effects.Consultants were less likely to provide intensive consulting care with each additional prior consultant on the case (1.2-1.7 percent) or if a prior consultant rendered intensive consulting care (20.6-21.5 percent) but more likely when prior consults were more concentrated across consultants (2.9-3.1 percent). Effects on consultants' total days consulting were similar.On average, consultants appeared to calibrate their care intensity for individual patients to maximize their value to all patients. Interventions for improving consulting care efficiency should seek to facilitate (not constrain) consultants' decision-making processes.

Project description:BackgroundSince 1992 ART clinics have been required to report outcome data. Our objective was to assess practitioners' opinions of the impact of public reporting of assisted reproductive technology (ART) outcomes on treatment strategies, medical decision-making, and fellow training.MethodsSurvey study performed in an academic medical center. Members of the Society of Reproductive Endocrinology and Infertility and the Society of Reproductive Surgery were recruited to participate in an online survey in April 2012.: Categorical survey responses were expressed as percentages. Written responses were categorized according to common themes regarding effects of reporting on participants' medical management of patients. The study was primarily qualitative and was not powered to make statistical conclusions.ResultsOf 1019 surveys sent, 323 participants (31.7%) responded from around the United States, and 275 provided complete data. Nearly all (273 of 282; 96.8%) participants responded that public reporting sometimes or always affected other providers' practices, and 264 of 281 (93.9%) responded that other practitioners were motivated to deny care to poor-prognosis patients to improve reported success rates. However, only 121 of 282 (42.9%) indicated that public reporting influenced their own medical management. The majority of respondents agreed that public reporting may hinder adoption of single embryo transfer practices (194 of 299; 64.9%) and contribute to the persistent rate of twinning in in vitro fertilization (187 of 279; 67%). A small majority (153 of 279; 54.8%) felt that public reporting did not benefit fellow training, and 58 (61.7%) of the 94 participants who trained fellows believed that having fellows perform embryo transfers reduced pregnancy rates. A small majority (163 of 277; 58.8%) of respondents reported their ART success rates on clinical websites. However, the majority (200 of 275; 72.7%) of respondents compared their success rates with those of other clinics. Finally, most respondents (211 of 277; 76%) believed that most centers that advertised their success rates did so in ways that were misleading to patients.ConclusionsPublic reporting of ART clinical outcomes is intended to drive improvement, promote trust between patients and providers, and inform consumers and payers. However, providers reported that they modified their practices, felt others denied care to poor-prognosis patients, and limited participation of trainees in procedures in response to public reporting of ART outcomes.

Project description:RationalePulmonologists frequently encounter indeterminate pulmonary nodules in practice, but it is unclear what clinical factors they rely on to guide the diagnostic evaluation.ObjectivesTo assess the current approach to the management of indeterminate pulmonary nodules and to determine the extent to which the addition of a hypothetical diagnostic blood test will influence clinical decision making.MethodsSelected pulmonologists practicing in the United States were invited to participate in a conjoint exercise based on 20 randomly generated cases of varying age, smoking history, and nodule size. Some cases included the result of a hypothetical blood test. Each respondent chose from among three diagnostic options for a patient: noninvasive monitoring (i.e., serial CT or positron emission tomography scan), a minor procedure (i.e., biopsy or bronchoscopy), or a major procedure (i.e., video-assisted thorascopic surgery or thoracotomy). Multivariate logistic regression was used to assess the impact of the three risk factors and the diagnostic blood test on decision making.Measurements and main resultsFour hundred nineteen physicians participated (response rate, 10%). One hundred fifty-three physician surveys met predetermined criteria and were analyzed (4% of all invitees). A diagnostic procedure was recommended for 23% of 6-mm nodules, versus 54, 66, 77, and 84% of nodules 10, 14, 18, and 22 mm, respectively (P?<?0.001). Older age limited recommendations for invasive testing: 54% of 80-year-olds versus 61, 64, 63, and 61% of patients 71, 62, 53, and 44 years of age, respectively (P?<?0.001). In multivariate analyses, nodule size, smoking history, age, and the blood test each influenced decision making (P?<?0.001).ConclusionsThe pulmonologists who participated in this survey were more likely to proceed with invasive testing, instead of observation or additional imaging, as the size of the nodule increased. The use of a hypothetical blood test resulted in significant alterations in the decision to pursue invasive testing.
