OBJECTIVES/OBJECTIVE:We surveyed the nation's internal medicine residency training program directors to determine the range and frequency of existing methods by which float experiences are evaluated. METHODS:We sent questionnaires to the program directors of all 396 internal medicine residency training program sites in the country. Information requested included program characteristics, months devoted to float experiences in each year of training, and the location and purpose of the rotation. Program directors were also asked to choose among descriptors characterizing the evaluative process. RESULTS:There were 139 responding programs (39%), 134 with data that could be aggregated. Responding programs were similar to all programs nationally in the distributions of size and university sponsorship. Overall, 76% of programs employed a night float for any period of time, and 71% currently had one, on average for 6.7 years. Mean months of float experience during residency was 2.4 months, significantly longer in programs that were not university based. Float experiences were evaluated in 89% of those programs who employed them, with ten different methods reported. University-based programs were significantly less likely to use chart review as a method of evaluation, but no other differences in methodology were significant. CONCLUSIONS:Float rotations are common among internal medicine residency training programs. Evaluative methods vary, but one or more are applied in the vast majority of programs.

BACKGROUND: Historical undertreatment of pain among inpatients has resulted in a national requirement for pain practice standards. OBJECTIVE: We hypothesized that adoption/promulgation of practice standards in January 2003 at 1 suburban teaching hospital progressively increased compliance with those standards and decreased pain. DESIGN: We retrospectively reviewed medical records each month during 2003, when pain standards were adopted with repeated, institution-wide, and nursing-unit-based interventions. Also, we reviewed discharges during 1 month in adjacent years. PATIENTS: We identified adult patients from 20 medical and surgical All-Payer Refined Disease Related Groupings (APRDRGs) in which opiate charges were most common in 2003. Among these, we considered patients actually receiving opiates and randomly chose equal numbers of matching subjects in each month of 2003. Matching was for APRDRG and complexity group. We also matched January 2003 discharges with those from January 2001, 2002, and 2004. MEASUREMENTS: For each patient, we captured 3 variables measuring standards compliance: percentage pain observations reported numerically, number of observations, and median time to reassessment after opiates. We also captured 3 pain variables: median pain score, rate of improvement in pain score, and total opiates dispensed. RESULTS: There were 360 qualifying discharges in 2003, and 75 in the other years. Numeric observations increased 15%, number of assessments 36%, and reassessment time decreased 60%. All changes were significant but occurred before standards implementation. Among pain measures, only rate of pain improvement changed, worsening slightly but significantly (-0.02 to -0.005 U/h), also before standards. CONCLUSIONS: Implementation of pain practice standards affected neither practice nor pain

Intensity of hospital services is often estimated by length of stay (LOS). Increasing demands for documentation in the medical record suggested to us an alternate method: weighing the chart. In a retrospective study, we compared LOS and chart weight as predictors of actual hospital costs at a community teaching hospital. We reviewed a sample of 123 patients randomly chosen from the medical service and stratified by phase of the academic year. Both least-squares regression and a multiple sampling/validating technique were used to derive mean cost per ounce of chart and per day of stay. Costs estimated from weight were within 7% and from LOS within 14% of measured actual costs among patients not used to derive the formulae. We conclude that the intensity of paper documentation closely reflects actual costs; the same may be true of bytes or key-strokes for electronic records

Discharge summaries are intended to transfer important clinical information from inpatient to outpatient settings and between hospital admissions. The authors created a point scale that rated summaries in 4 key areas and applied the scale at a community teaching hospital over 3 years. Charts of 150 patients were selected equally from those discharged early and late in the academic year. Residents dictated all summaries after July 2003 using a prominently displayed template. Two residents and a senior physician assessed dictation quality. Considerable differences were found among raters, particularly in the evaluation of style. The average of the 3 raters' scores improved 21%, and dictation length decreased 67% after introduction of the template (P < .001). No relationship was found among service intensity (measured as chart weight), dictation length (measured in lines), and quality. Measured by a comprehensive rating scale, the quality of discharge summaries increased with use of a template while their length decreased

BACKGROUND: There is limited information concerning the risks for, and occurrence of, cardiovascular complications because of GI endoscopy. Published data are based on questionnaire surveys, which have a potential for bias. Moreover, available studies pertain exclusively to out-patients. METHODS: In-patients and day-stay patients who incurred charges for endoscopy with endoscopic procedure coding from 1999 through 2001 were identified from a financial database for all 9 hospitals in a large health care system. From these patients, those considered 'at risk' for cardiovascular complications were selected based on charges for cardioactive medications, cardiac enzyme determinations, or intensive care services on the day of or the day after endoscopy. Medical records were reviewed for 25% of these patients, selected at random, noting demographics, history, and a modified Goldman score in patients with cardiovascular complications (defined as arrhythmia, chest pain or anginal equivalent, hypotension or myocardial infarction occurring within 24 hours after endoscopy). Identical information was obtained from a random sample of 0.5% of the chart records for all patients undergoing endoscopy. RESULTS: Patients who underwent endoscopy were not reliably identified for one hospital. This hospital was omitted from the calculation of the extrapolated rate of complication occurrence, but patients identified through chart review as having or not having a complication after endoscopy were included in the risk analysis. The extrapolated rate of occurrence of cardiovascular complications was 308: 95% CI [197, 457] per 100,000 procedures. Independent risk factors were: male gender, modified Goldman score, and use of propofol. CONCLUSIONS: In this study of patients undergoing hospital-based GI endoscopy, the risk of procedure-related cardiovascular complications was 2 to 70 times higher than previously reported. This finding may be ascribed to differences in the populations sampled and to a case-finding method that minimized reporting and ascertainment biases

Warfarin induction is accomplished by titrating dosage to coagulation test results. Algorithms can guide this process but not identify the starting dose. We hypothesized that an initial warfarin dose approximating the maintenance value would safely enhance rapidity of induction. In a randomized trial we compared a fixed-dose to a maintenance-dose strategy for beginning warfarin therapy. To predict the maintenance dose among patients with differing warfarin requirements we performed regression analysis on clinical factors derived from chart review. Four community hospitals supplied records for retrospective analysis. The prospective trial was conducted in one, a 350-bed teaching institution. A sample of inpatients anticoagulated during 1998 formed the development set for retrospective study; a 1999 sample formed the validation set. A one year trial recruited consecutive eligible inpatients initiated on warfarin. We randomly assigned patients to a first warfarin dose calculated using our regression formula or fixed at 5 mg. All patients' subsequent doses were determined (as a percentage of initial) from coagulation testing. We compared days to anticoagulation, hospitalized hours, complications, and activity of factor II and protein C in a patient sample at intervals after induction. Weight, age, serum albumin, and presence of malignancy explained 25-30% of variance in maintenance dose. Ninety patients (44 calculated-dose and 46 standard-dose) evaluated in the clinical trial. Mean time to anticoagulation (among patients achieving anticoagulation) was 4.2 and 5.0 days, respectively (p = 0.007). We observed no significant differences in other endpoints. Individualized initial dosing may safely hasten warfarin induction

Identification of alternatives to manual chart review might improve efficiency in quality improvement work. This study at a large community teaching hospital in central New Jersey considered whether selected charges from a patient-level costs database could identify compliance with Sixth Scope of Work indicators in congestive heart failure (CHF). Charges resulting from specific tests, from test outcomes, and from prescribed treatments were identified from among 75 randomly chosen patients with CHF. In the sample 65% (as determined by database analysis) and 69% (as determined by chart review) complied with the principal peer review organization criterion. This difference was less than that found between review and re-review of study charts

CONTEXT: The impact of residents on hospital finance has been studied; there are no data describing the economic effect of residents on attending physicians. OBJECTIVE: In a community teaching hospital, we compared allowable inpatient visit codes and payments (based on documentation in the daily progress notes) between a general medicine teaching unit and nonteaching general medicine units. DESIGN: Retrospective chart review, matched cohort study. SETTING: Six hundred fifty-bed community teaching hospital. PATIENTS: Patients were discharged July 1998 through February 1999 from Saint Barnabas Medical Center. We randomly selected 200 patients in quartets. Each quartet consisted of a pair of patients cared for by residents and a pair cared for only by an attending physician. In each pair, 1 of the patients was under the care of an attending physician who usually admitted to the teaching service, and 1 was under the care of a usually nonteaching attending. Within each quartet, patients were matched for diagnosis-related group, length of stay, and discharge date. MAIN OUTCOME MEASURES: We assigned the highest daily visit code justifiable by resident and attending chart documentation, determining relative value units (RVUs) and reimbursements allowed by each patient's insurance company. RESULTS: Although more seriously ill, teaching-unit patients generated a mean 1.75 RVUs daily, compared with 1.84 among patients discharged from nonteaching units (P =.3). Median reimbursement, daily and per hospitalization, was similar on teaching and nonteaching units. Nonteaching attendings documented higher mean daily RVUs than teaching attendings (1.83 vs 1.76, P =.2). Median allowable reimbursements were $267 per case ($53 daily) among teaching attendings compared with $294 per case ($58 daily) among nonteaching attendings (Z = 1.54, P =.1). When only the resident note was considered, mean daily RVUs increased 39% and median allowable dollars per day 27% (Z = 4.21, P <.001). CONCLUSIONS: Nonteaching attendings appear to document their visits more carefully from a billing perspective than do teaching attendings. Properly counter-documented, resident notes could substantially increase payments to attending physicians

OBJECTIVE: The effect of care by medical residents on hospital length of stay (LOS), indirect costs, and reimbursement was last examined across a range of illnesses in 1981; the issue has never been examined at a community hospital. We studied resource utilization and reimbursement at a community hospital in relation to the involvement of medical residents. DESIGN: This nonrandomized observational study compared patients discharged from a general medicine teaching unit with those discharged from nonteaching general medical/surgical units. SETTING: A 620-bed community teaching hospital with a general medicine teaching unit (resident care) and several general medicine nonteaching units (no resident care). PATIENTS: All medical discharges between July 1998 and February 1999, excluding those from designated subspecialty and critical care units. MEASUREMENTS AND MAIN RESULTS: Endpoints included mean LOS in excess of expected LOS, mean cost in excess of expected mean payments, and mean profitability (payments minus total costs). Observed values were obtained from the hospital's database and expected values from a proprietary risk-cost adjustment program. No significant difference in LOS between 917 teaching-unit patients and 697 nonteaching patients was demonstrated. Costs averaged $3,178 (95% confidence interval (CI) +/- $489) less than expected among teaching-unit patients and $4,153 (95% CI +/- $422) less than expected among nonteaching-unit patients. Payments were significantly higher per patient on the teaching unit than on the nonteaching units, and as a result mean, profitability was higher: $848 (95% CI +/- $307) per hospitalization for teaching-unit patients and $451 (95% CI +/- $327) for patients on the nonteaching units. Teaching-unit patients of attendings who rarely admitted to the teaching unit (nonteaching attendings) generated an average profit of $1,299 (95% CI +/- $613), while nonteaching patients of nonteaching attendings generated an average profit of $208 (95% CI +/- $437). CONCLUSIONS: Resident care at our community teaching hospital was associated with significantly higher costs but also with higher payments and greater profitability
