Endoscopy training during general surgery residency.

The endoscopic experience of surgical residents was evaluated following the introduction of a formal surgical endoscopy program, which consisted of a 2-month rotation, generally at the postgraduate year 2 level. The resident was assigned to one attending surgeon and also had a formal laboratory session. There were many benefits, including a significant increase in endoscopic encounters. Program directors should seriously consider setting up a rotation with an experienced surgeon-endoscopist.

Formal endoscopy training for senior and junior house staff.

The upper endoscopic experience of junior and senior surgical residents was analyzed before (period 1) and after (period 2) creating a 2-month rotation with a dedicated surgical endoscopist. Three hundred sixty-two endoscopies were performed during the study period, with 295 (81%) being performed after formalizing training. A chi-square analysis was performed and found to be statistically significant for each group when compared to a control experience with colonoscopy. We conclude that a dedicated block of time and a committed surgical attending physician will have a significantly positive impact on resident caseload. Furthermore, the added benefits of being more closely involved with the patient rather than relying on another discipline will add to the resident's educational experience.

Percutaneous gastrostomy made simple.

The use of percutaneous endoscopic gastrostomy has obviated the necessity of laparotomy for enteral access. The authors propose a new technique for introduction of the gastrostomy tube. It entails use of the laparoscopic trocar to gain entrance into the gastric lumen.

Intraoperative cholangiography revisited.

The charts of 1351 patients undergoing cholecystectomy at our institutions from 1985 through 1989 were reviewed retrospectively to evaluate the indications for and the success of intraoperative cholangiography. A total of 800 patients underwent intraoperative cholangiography. They were divided into two groups based on the absence (CR-) or presence (CR+) of clinical and/or operative criteria suggestive of the existence of common bile duct stones. Intraoperative cholangiography in CR- patients was of limited benefit, being negative (normal) in 95.7%, true-positive (abnormal) in 3.3%, and false-positive in 1%. False-positive intraoperative cholangiography resulted in unnecessary common bile duct explorations. Intraoperative cholangiography in CR+ patients proved useful, avoiding unnecessary common bile duct exploration in 55%. In those select CR+ patients with palpable common bile duct stones or cholangitis, little additional information was gained by the intraoperative cholangiography. We conclude that routine screening intraoperative cholangiography in CR- patients be reconsidered, as should the use of intraoperative cholangiography in CR+ patients with a palpable common bile duct stone or cholangitis. Intraoperative cholangiography in the remainder of CR+ patients proved beneficial and should be continued.

An appraisal of small and diminutive colonic polyps.

A retrospective review of all colonoscopic polypectomies performed in a busy surgical endoscopy unit over a 6-month period was undertaken. All patients were included who presented with colonic polyps measuring less than 1 cm in diameter for which sufficient specimens were available for histopathologic examination. In all, 262 were polyps removed from 206 patients; of these, 158 (60%) were neoplastic. There was a statistically significant predilection for polyps in the right colon to be neoplastic. Worrisome histologic patterns (severe dysplasia, carcinoma in situ, or invasive carcinoma) were seen in 18 specimens (6.5%). In two patients, polypoid carcinoma could be identified; in one case it involved a lesion measuring 0.2 cm in diameter. Since these lesions exhibit no distinctive gross features, only their endoscopic removal and histologic study can ensure proper diagnosis and treatment.

Route of admission and hospital costs for urologic patients.

This study of 2,549 urology patients examined resource consumption by route of admission into the hospital. Almost all urologic admissions were more expensive as emergencies. These more expensive emergency urologic admissions had higher diagnostic costs, a longer hospital length of stay, and a greater severity of illness than their less expensive non-emergency counterpart. The more expensive emergency admission had a high referral rate to urology from non-urologic clinical services. These findings suggest that efficiency might be improved in the emergency urologic patients by increasing the speed of diagnosis and admission of patients to the appropriate clinical service (urology).

Financial risk and hospital cost for elderly patients. Age- and non-age-stratified medical diagnosis related groups.

The purpose of this study was to analyze hospital resource consumption for Medicare patients in non-age- and age-stratified medical diagnosis related groups (DRGs). This study of patients in 74 non-age-stratified DRGs (N = 3643) and 113 age-stratified DRGs (N = 2898) demonstrated that older medical patients (usually greater than or equal to 75 to 80 years of age) had (on average) higher total hospital costs, a longer hospital length of stay, more diagnoses per patient, a greater percentage of outliers, and a higher mortality compared with younger patients in these same DRGs. These findings raise the question of the equity of DRG payment vis-à-vis older Medicare patients in both non-age- and age-stratified medical DRGs. Financial disincentives to treat older medical patients may limit both their access and quality of care in the future.

Financial risk, hospital cost, complications, and comorbidities in surgical noncomplication- and noncomorbidity-stratified diagnostic related groups.

The purpose of this study was to analyze resource consumption in the 147 non-complicating condition-stratified surgical diagnostic related groups (DRGs). Analysis of 2647 surgical patients in these non-CC-stratified surgical DRGs demonstrated that patients with more CCs per DRG generated higher total hospital costs, a longer hospital length of stay, a greater percentage of procedures per patient, financial risk under DRG payment, more outliers, and a higher mortality rates than patients in these same DRGs with fewer CCs. These findings suggest that the current DRG classification system may be inequitable to certain groups of patients or types of hospitals vis-à-vis the non-CC-stratified surgical DRGs. Financial disincentives to treat these patients may affect both their access and quality of care in the future.

Repeat colonoscopy after endoscopic polypectomy.

The records of all patients undergoing endoscopic polypectomy between December 1979 and December 1982 were reviewed. One hundred seventy-two patients underwent colonoscopic polypectomy in the absence of carcinoma or inflammatory bowel disease. Of these, the polyp could not be retrieved in 4, and 19 were lost to follow-up. One hundred forty-nine patients underwent subsequent endoscopy from one to four years after the initial polypectomy. Seventy-five (50.3 percent) of the patients developed new polyps. Although 61 of the 75 patients with new polyps were identified in the first two years, new polyps were noted throughout all four years. The presence of multiple polyps on the initial examination was statistically significant in predicting new polyps. The age and sex of the patients, size of the polyps, and the presence of atypia did not identify patients at higher risk for new polyps. The data indicate that new polyps are more likely to develop in patients who had a previous polyp. It would appear that annual examinations should be performed until two successive examinations are negative. Following a second negative examination, reexamination at two- or three-year intervals, unless symptomatic, would appear to be adequate.

The identifier concept: clinical variables to manage costs for surgical patients.

Previous studies at Long Island Jewish Medical Center had shown that certain clinical variables (identifiers) would differentiate hospital charges within surgical diagnosis-related groups (DRGs). This current project demonstrated that the clinical variables of mode of admission (emergency versus nonemergency), blood transfusion, and surgical intensive care unit admission could stratify both differences in severity of illness and charges for patients in general surgical DRGs. These findings suggest that these three identifiers may be useful to physicians and hospital administrators in evaluating surgical patients for differences in resource consumption during their hospitalization, for better management of hospital-based inpatient costs.

Value of routine pathology in herniorrhaphy performed upon adults.

The value of routine pathologic study of specimens taken at herniorrhaphy performed upon adults was assessed. All 789 patients who underwent inguinal or femoral herniorrhaphy at the Long Island Jewish Medical Center from January 1983 through July 1984 were studied. Patients were classified into five groups; 1, no specimen was sent for pathologic evaluation; 2, confirmation of hernia sac; 3, confirmation of hernia sac with additional expected pathologic findings (such as lipoma or hydrocele); 4, unexpected additional pathologic findings which appeared abnormal at operation, and 5, unexpected additional pathologic findings which appeared normal at operation. During this time period there were 935 herniorrhaphy procedures performed. Three of 1,020 specimens examined contained unexpected pathologic findings (groups 4 and 5): non-Hodgkin's lymphoma, liposarcoma and atypical lipoma. Only one specimen (group 5) with an abnormal pathology report showed an atypical lipoma which appeared normal at operation (0.098 per cent). The outcome of the operation was not altered by the pathology results in these three patients from either group 4 or 5. Aggregate charges for all specimens was $30,528.00 (a mean charge per patient of $48.00). Annual savings to the health care system of the United States by omitting routine pathologic examination of specimens from groups 1, 2 and 3 would be $18 million. Although there may be some justification for routine tissue testing for medical and legal reasons and quality assurance purposes or for specimens which appeared abnormal at operation, these data suggest that for patients who undergo herniorrhaphy, little positive effect on the outcome is gained from routine pathologic examination of specimens which appeared normal at operation.

Mode of admission and cost for surgical DRGs.

The purpose of this study was to confirm the hypothesis that emergency department admissions were more expensive than their nonemergency counterparts per diagnosis-related group (DRG) and to see if this characteristic was displayed across many hospitals. All surgical admissions (N = 39,682) to the 11 acute-care hospitals of the New York City Health and Hospitals Corporation were analyzed during an 18-month period to yield a study population (N = 26,569) of matched DRG subgroups (ED vs nonED) at each hospital of at least five patients per variable for that particular DRG. A cost-per-patient analysis was conducted for each admission. Total costs for the study population were $163,360,636. A total of 75.8% of surgical admissions (N = 20,143) were admitted in DRGs in which ED admissions were more costly than their nonED-matched counterparts. The following was the trend in percentage of total specialty admissions in DRGs in which ED admissions were more costly than nonED admissions: urology (88.4%); ear, nose, and throat (86.2%); general and vascular (80.1%); cardiothoracic (78.0%); orthopedics (75.6%); plastic surgery (62.1%); neurosurgery (60.5%); and ophthalmology (46.0%). Route of admission (ED vs nonED) was an identifier of higher-cost patients per DRG across hospitals in a large public hospital system. These data demonstrate that hospitals with substantial numbers of surgical ED admissions may face significant financial risk under DRG reimbursement, and suggests that the DRG system does not adequately compensate hospitals for the higher cost of the emergency surgical admission.

Anorectal infiltration anesthesia in the prone position.

A safe technique of infiltration anesthesia for anorectal procedures is described. It eliminates patient discomfort and allows the surgeon to work with the patient in the prone position.

Prevalence of antibodies to HTLV-I, -II, and -III in intravenous drug abusers from an AIDS endemic region.

Antibody prevalences for human T-cell lymphotropic virus (HTLV) types I, II, and III were determined for 56 intravenous drug abusers from Queens, NY. While control serum samples lacked antibodies to all HTLV subgroups, seropositivity among drug users was 41% for HTLV-III, 18% for HTLV-II, and 9% for HTLV-I. Infection by HTLV-I and -II occurred independently of HTLV-III infection. Blacks had greater HTLV-III antibody prevalence than whites (54% vs 16%) and were more likely than whites to be seropositive for HTLV-I or -II (46% vs 11%). They exhibited a greater incidence than whites of double infection with HTLV-I or -II and HTLV-III (27% vs 0%), and 73% were seropositive for at least one of the viruses, compared with only 26% of the whites. The increased HTLV-I and -II infection seen in intravenous drug users suggests that once introduced into a population, these viruses may be transmitted by the same routes as HTLV-III. Transmission may have been restricted mainly to blacks in this study because of local drug use practices.

Source of admission and cost: public hospitals face financial risk.

We studied all admissions to the 11 acute care hospitals of the New York City Health and Hospitals Corporation (April 1983-September 1984) matching emergency room (ER) admitted diagnostic related group (DRG) subgroups in each hospital with at least five non-ER admitted patients (N = 222,961). Mean cost per ER patient ($8,385) was greater than non-ER mean cost per patient ($4,386) for Medicare and non-Medicare. Our data suggest that public hospitals with a high proportion of ER admissions may be at a financial disadvantage under DRG reimbursement.

Surgonomics: the cost dynamics of craniotomy.

Prospective payment systems using the diagnostic related group (DRG) mechanism are being phased in for Medicare inpatient hospital care. The purpose of this study was to examine a common neurosurgical procedure (001), craniotomy without trauma, and characterize the cost dynamics of this DRG. All patients (n = 50) treated in this DRG at the Long Island Jewish Medical Center during 1983 had their financial charges exclusive of physician fees examined. The findings were: (a) each hospital service category had wide charge variances around the mean; (b) emergency (ER) admissions were 200% more expensive than nonemergency (non-ER) admissions; (c) ER admissions seemed to have no greater severity of illness than non-ER admissions, but had a significantly different referral pattern (i.e., admission from the ER to a nonneurosurgical service with a subsequent neurosurgical referral); (d) this DRG when grouped into clinical "subproducts" (i.e., craniotomy for tumor, hematoma, hydrocephalus, aneurysm, benign cyst, and other) showed marked charge differences; and (e) the most expensive 25% of patients had five times higher charges than the least expensive 25% for both ER and non-ER admissions. This type of financial analysis may give surgeons a methodology with which to address the problems of cost containment in a more serious manner.

Surgonomics and cost containment.

The implementation of Diagnostic Related Groups (DRGs) and ALL PAYOR SYSTEMS will force surgeons to examine the consumption of hospital resources. Previous study results at our institution indicated that almost 90 per cent of common surgical DRGs would be unprofitable under the Prospective Payment System (PPS). This study was done to examine the financial components of a common surgical DRG that would be unprofitable, examine appropriateness of hospital expenditures and propose strategies for cost containment without sacrificing quality of care. We studied all patients (215) in DRG 162 (inguinal and femoral hernia procedures, ages 18 to 69 years, without a complicating condition) at the Long Island Jewish-Hillside Medical Center from 1 January 1983 until 31 December 1983. Hospital charges were examined by hospital service category and aggregated by total dollars per category, patient mean dollars plus or minus standard error of mean per category and patient totals. Total hospital charges for this DRG were $493,432.00, DRG reimbursement (1983 Federal Register) would have been $447,799.00, resulting in a net loss (deficit) to the hospital of $47,434.00 or $212.00 per patient. Hospital services (room and board, laboratory and ancillaries) were overused in the treatment of this DRG. Strategies involving quite modest decreases in length of stay and use of ancillary services (laboratory, x-ray, electrocardiogram) would save at least $60,000.00 and make this a profitable DRG.
