A randomized trial of providing house staff with patient social history information. Effect on patient outcomes.

The purpose of this project was to assess if providing physicians (house staff) with routine comprehensive social history information on their patients will improve patient outcomes. Comprehensive social history information was gathered over a 5-month period on 134 consecutive patients. Patients were randomized to have social history information provided or not provided to the resident physician caring for them. Outcomes of interest were: patient satisfaction, length of stay, and early unplanned readmission. Analysis was with analysis of covariance, controlling for patient severity of illness and amount of social history information documented by the house officer. Outcomes were the same for patients for whom house staff were provided social history information versus those for whom the information was not provided. The authors conclude that providing house staff with routine comprehensive social history information did not influence patient outcomes.

Internal medicine residency training and outcomes.

OBJECTIVE: To review the impact of the clinical education of internal medicine residents on patients' outcomes. DATA SOURCES AND STUDY SELECTION: English-language studies of the relation between internal medicine housestaff training and patients' outcomes were systematically identified by a MEDLINE search and from bibliographies and reference lists of recently published articles. MAIN RESULTS: We hypothesized that the primary impact of internal medicine residency training on patients' outcomes would be the result of: (1) the inexperience of the residents; (2) the heavy workload these inexperienced residents are expected to manage: or (3) some structural feature of the internal medicine teaching services, such as the discontinuity of patient care inherent in night float systems and the fact that residents rotate to different services each month. We also hypothesized that residents may in may ways provide superior care, and many actually improve certain patient outcomes. Housestaff inexperience, workload, and structural features that promote discontinuity have been shown to affect especially outcomes of resource utilization, length of stay, and patient satisfaction. No study has demonstrated that internal medicine residents contribute to excess patient morbidity or mortality. However, the published studies in this area are for the most part retrospective and were conducted 10 to 15 years ago. The full extent of the untoward (or the beneficial) effects of internal medicine residency training on patients' outcomes is unknown. CONCLUSIONS: Multisite, prospective studies would remedy the deficiencies in the published research in this area and would yield the most valid insight into the range and extent of the effects of housestaff training on patients' outcomes. In the absence of such studies and in a rapidly changing managed care environment, academic medical centers and departments of medicine need to be aware of those aspects of the clinical education of residents that are most likely to affect patients' outcomes.

Intern call structure and patient satisfaction.

Our institution has instituted "short-call" and "nightfloat" systems to reduce the number of admissions to the traditional "long-call" housestaff. However, the nightfloat system introduces increased discontinuity to patient care, and interns may spend less time with short-call patients because they are nor required to spend the night on-call. Discontinuity and less time spent with patients may result in decreased patient satisfaction. Over a 6-month period, data were collected on 145 consecutive patients admitted to a teaching Veterans Affairs Medical Center with the primary diagnoses of congestive heart failure and chronic obstructive pulmonary disease. We found that patients admitted to either short-call or nightfloat interns were significantly less satisfied with their care than patients admitted to long-call housestaff, controlling for intern gender, patient age, and patient severity of illness (p = 0.02). Residency program directors need to realize that changes in the structure of teaching environment may have an impact on patient satisfaction.

Assessing residents' readiness for working in a managed care environment.

PURPOSE: A the pilot study to assess the state of residents' training for practice in a managed care environment. METHOD: In May and June 1996, all 178 residents at the University of Kentucky College of Medicine in six programs were approached to participate in the study. An instrument was created to assess the residents' knowledge of, attitudes toward, and exposure to managed care, as well as their perceptions of their residency experience. Attitudinal items were measured using a five-point Likert scale (1 = strongly agree, 5 = strongly disagree), as were the assessments of experience (1 = excellent, 5 = poor). Bivariate statistics were computed between the number of correct responses to the knowledge questions and both the year of training and reported exposure to managed care. The relationship between exposure and knowledge was analyzed using a two-tailed t-test. A Pearson product-moment correlation was computed between residents' knowledge and year of training. RESULTS: In all, 140 (79%) residents participated, 76% of whom were men. Seventy-three percent of the residents rated their experiences as fair or poor; the mean rating across all the residents was 3.8 (SD, 0.8). Among those reporting some exposure, attitudes toward the effectiveness of their exposure generally ranged from neutral to negative. Across all the residents, the mean number of correct responses to the five knowledge questions was 3.2 (SD, 1.1). No statistically significant relationship was found between year of training and the number of correct responses. The residents who reported some exposure to managed care had a significantly higher mean number of correct responses than did those with no reported exposure (3.4, SD, 1.1, vs 2.8, SD, 1.3, p = .04). CONCLUSION: The residents reported limited exposure to managed care and that their training experience did not prepare them for working in managed care; this was confirmed (in a limited way) by the responses to the knowledge questions. As managed care expands in the United States, the systematic incorporation of managed care instruction into training is necessary to appropriately prepare residents for future practice.

Does pediatric housestaff experience influence tests ordered for infants in the neonatal intensive care unit?

OBJECTIVE: To assess the relationship between the experience of pediatric housestaff and tests ordered on infants in the neonatal intensive care unit (ICU). DESIGN: Prospective, cohort study over one full academic year. SETTING: One academic Level III neonatal intensive care nursery. PATIENTS: Data were collected prospectively on all 785 infants admitted to the neonatal ICU from July 1993 to June 1994. These infants were cared for by 14 different categorical pediatric housestaff. MEASUREMENTS AND MAIN RESULTS: Our neonatal ICU has either a resident or an intern on-call by himself/herself at night, affording us a natural setting to compare intern vs. resident test ordering. The outcomes of interest were number of arterial blood gases, radiographs, and electrolytes ordered per infant by the on-call pediatric houseofficer, as tabulated the morning after the call night. Control variables included the severity-of-illness of the individual infant (using the Neonatal Therapeutic Intervention Scoring System), the workload of the houseofficer (number of patients, number of admissions), and supervision (rounding frequency and on-call attending). Controlling for the severity-of-illness of the infant, the workload on the call night, and supervision with multiple linear regression, we found that interns ordered significantly (p = .02) greater numbers of arterial blood gases per infant than residents, amounting to some 0.33 blood gases per infant per call night (3.22 vs. 2.89 arterial blood gases per infant per night). This increase of 0.33 blood gases per infant amounts to interns ordering $169 more arterial blood gases per call night at our institution. There was no difference between interns and residents in ordering radiographs or electrolytes. CONCLUSION: Interns order significantly more arterial blood gases per infant than junior and senior residents on-call in the neonatal ICU. Additional study is required to see if the experience of housestaff is associated with a broader array of neonatal outcomes, such as morbidity and mortality.

Housestaff experience, workload, and test ordering in a neonatal intensive care unit.

BACKGROUND: Little is known of how the inexperience or the clinical workload of housestaff affects the decisions they make in the neonatal intensive care unit (NICU). The authors hypothesized that less experienced interns would order more tests per infant than more experienced residents, especially under conditions of heavy workload. METHOD: The NICU at the University of Kentucky A. B. Chandler Medical Center has either an intern or a resident on call by himself or herself at night, a natural setting to compare test ordering by interns and residents. The authors counted the numbers of X rays, analyses of arterial blood gases (ABGs), and electrolyte determinations ordered by the house officers on call for 321 infants from July through November 1993. Data for nine interns and seven residents were compared using multivariate linear regression. RESULTS: When workload became heavier (about five NICU patients), the interns increased their ordering of ABGs per infant to a significantly greater degree than did the residents (p = .01), with the difference being even greater on weekends when the housestaff were under less supervision (p = .004). CONCLUSION: As workload becomes greater in the NICU, interns order more ABGs per infant than do more experienced residents, especially when the interns are less supervised.

Housestaff social history knowledge. Correlation with evaluation of interpersonal skills.

It was hypothesized that internal medicine housestaff who inquire into their hospital patients' social histories would be rated by nurses and attendings as having better interpersonal skills. Thirty-seven internal medicine housestaff were asked to answer a questionnaire regarding the social history of up to three of their hospital patients. The score on these questionnaires was then compared to evaluations by nurses and attendings of housestaffs' interpersonal skills. We found that nurses' evaluations of housestaff interpersonal skills correlated with performance on the social history questionnaire, while attendings' evaluations did not. Social history inquiry by housestaff may be a marker for housestaff humanistic and interpersonal skills.

Knowledge and experience with Alzheimer's disease. Relationship to resuscitation preference.

BACKGROUND: Previous studies suggest that 20% to 67% of patients would desire cardiopulmonary resuscitation (CPR) even if they had advanced Alzheimer's disease. These preferences were not affected by education about CPR. We hypothesized that CPR preferences in scenarios involving Alzheimer's disease are influenced more by knowledge of or experience with Alzheimer's disease than by knowledge of CPR and its outcomes. METHODS: We performed a random digit-dialing telephone survey of adult Kentuckians in June 1993. A total of 661 persons responded. We asked respondents whether they have had a friend or family member with Alzheimer's disease and whether they had cared for that person at home. We then assessed basic knowledge of Alzheimer's disease and CPR. We read to one half of respondents an educational paragraph describing CPR and its outcomes. Finally, we asked respondents their CPR preference if they were to develop Alzheimer's disease. RESULTS: Overall, 22% of respondents would probably or definitely want CPR if they had Alzheimer's disease. With the use of simultaneous multiple linear regression, predictors of refusing CPR in scenarios involving Alzheimer's disease included knowledge of or experience with Alzheimer's disease (P < .001), older age (P < .001), greater income (P < .004), female sex (P < .01), and nonwhite race (P < .04). Baseline knowledge of CPR did not affect CPR preferences, nor did being read the educational paragraph. CONCLUSIONS: Cardiopulmonary resuscitation preferences in scenarios involving Alzheimer's disease are strongly associated with knowledge of or experience with Alzheimer's disease more so than with knowledge of CPR. These findings suggest that in eliciting patients' CPR preferences in an advanced directive, care must be taken that patients understand the condition presented in the scenario (eg, Alzheimer's disease).

Housestaff's knowledge of their patients' social histories.

PURPOSE: To assess the extent to which house officers know the social histories of their hospital patients, and to examine the factors that influence social history knowledge. METHOD: In October-November 1992, all 31 internal medicine housestaff rotating on the hospital inpatient services at the University of Kentucky A. B. Chandler Medical Center completed questionnaires regarding the social histories of up to three of their patients. Responses were analyzed using simultaneous multiple linear regression analysis. RESULTS: Standard questions about social history were answered correctly only 29% of the time (two of seven items). The overall knowledge of patients' social histories was significantly less for supervising residents than for interns (p = .03) and, independently, for housestaff with greater patient loads (p = .04). Knowledge of a patient's social history was not related to the particular inpatient service, time the patient was admitted, or other characteristics of the patients or residents. CONCLUSION: The internal medicine residents' knowledge of their hospital patients' social histories was limited, particularly when the residents had relatively heavy patient loads or supervisory roles in patient care. The data suggest that patients' social histories may have been underemphasized during the residents' training.
