OBJECTIVE: To investigate the reliability of collecting colorectal stage information from pathology reports and general practitioners in Queensland, Australia. METHODS: A longitudinal study of colorectal cancer survivors conducted in 2003 and 2004 (n=1966, response rate=57%) obtained stage information from clinical specialists (n=1334), general practitioners (GP) (n=1417) and by extracting stage from pathology reports (n=1484). Reliability of stage information was determined by comparing stage from GPs and pathology reports with that reported by the clinical specialists, using a weighted kappa. RESULTS: GPs and pathology reports each had a similar level of agreement with clinical specialists, with kappa scores of 0.77 (0.75-0.80) (n=1042) and 0.78 (0.75-0.81) (n=1152), respectively. Results were similar when restricting to records staged by all three methods (n=847). GPs had similar levels of agreement with clinical specialists within each stage, although pathology reports tended to under-stage patients in Stage D (0.37). Collapsing stage into two categories (A or B, C or D) increased the reliability estimates from the pathology reports to 0.91 (0.88-0.93), but there was little change in GP estimates 0.79 (0.75-0.83). CONCLUSIONS: Extractions from pathology reports are a valid source of broad stage information for colorectal cancer. IMPLICATIONS: In the absence of clinical stage data, access to pathology records by population-based cancer registries enables a more accurate assessment of survival inequalities in colorectal cancer survival. 相似文献

Background
Hundreds of thousands of surgical arthroscopy procedures are performed annually in the United States (US) based on MRI findings. There are situations where these MRI findings are equivocal or indeterminate and because of this clinicians commonly perform the arthroscopy in order not to miss pathology. Recently, a less invasive needle arthroscopy system has been introduced that is commonly performed in the physician office setting and that may help improve the accuracy of diagnostic findings. This in turn may prevent unnecessary follow-on arthroscopy procedures from being performed.Objective
The purpose of this analysis is to determine whether the in-office diagnostic needle arthroscopy system can provide cost savings by reducing unnecessary follow on arthroscopy procedures.Methods
Data obtained from a recent trial and from a systematic review were used in comparing the accuracy of MRI and VisionScope needle arthroscopy (VSI) with standard arthroscopy (gold standard). The resultant false positive and false negative findings were then used to evaluate the costs of follow-on procedures. These differences were then modeled for the US patient population diagnosed and treated for meniscal knee pathology (most common disorder) to determine if a technology such as VSI could save the US healthcare system money. Data on surgical arthroscopy procedures in the US for meniscal knee pathology were used (calendar year [CY] 2010). The costs of performing diagnostic and surgical arthroscopy procedures (using CY 2013 Medicare reimbursement amounts), costs associated with false negative findings, and the costs for treating associated complications arising from diagnostic and therapeutic arthroscopy procedures were assessed.Results
In patients presenting with medial meniscal pathology (International Classification of Diseases, 9th edition, Clinical Modification [ICD9CM] diagnosis 836.0), VSI in place of MRI (standard of care) resulted in a net cost savings to the US system of US$115–US$177 million (CY 2013) (use of systematic review and study data, respectively). In patients presenting with lateral meniscus pathology (ICD9CM 836.1), VSI in place of MRI cost the healthcare system an additional US$14–US$97 million (CY 2013). Overall aggregate savings for meniscal (lateral plus medial) pathology were identified in representative care models along with more appropriate care as fewer patients were exposed to higher risk surgical procedures.Conclusions
Since in-office arthroscopy is significantly more accurate, patients can be treated more appropriately and the US healthcare system can save money, most especially in medial meniscal pathology. 相似文献5.

There is a shortage of information on the epidemiology of digestive disease in developing countries. In the belief that such information will inform public health priorities and epidemiological comparisons between different geographical regions, we analysed 2132 diagnostic upper gastrointestinal endoscopy records from 1999 to 2005 in the University Teaching Hospital, Lusaka, Zambia. In order to clarify unexpected impressions about the age distribution of cancers, a retrospective analysis of pathology records was also undertaken. No abnormality was found in 31% of procedures, and in 42% of procedures in children. In patients with gastrointestinal haemorrhage, the common findings were oesophageal varices (26%), duodenal ulcer (17%) and gastric ulcer (12%). Gastrointestinal malignancy was found in 8.8% of all diagnostic procedures, in descending order of frequency: gastric adenocarcinoma, oesophageal squamous carcinoma, Kaposi's sarcoma, oesophageal adenocarcinoma. Data from endoscopy records and pathology records strongly suggest that the incidence in adults under the age of 45 years is higher than in the USA or UK, and pathology records suggest that this effect is particularly marked for colorectal carcinoma. 相似文献

OBJECTIVES: To determine the completeness and accuracy of ICD-9-CM codes allocated by primary health care physicians in their computerized medical records and evaluate the effects of improvement procedures. METHODS: The codes of 87,806 patients assigned to 56 primary care physicians in the Basque National Health Service in Spain, were evaluated 3 times over a 1-year period according to the following criteria: correspondence to a valid ICD-9-CM code, agreement between diagnosis and code, and the percentage of visits with an unspecified reason for consultation. Finally, the mean number of unique diagnoses and rates of diagnostic groups in the 84,136 patients that remained with the same physician for a minimum of 6 months were contrasted with another previously registered morbidity database. Two interventions were performed to improve coding: detected errors were corrected centrally and physicians were assessed and given information on their individual results. RESULTS: Diagnoses lacking an ICD-9-DIC code decreased from 59% in the first assessment to 2% at the end of the study period. The percentage of coding mistakes (discrepancies in episode diagnosis and ICD-9-CM code) decreased from 17% to 3%. The mean annual number of diagnoses per patient was slightly lower than that in the reference database (2.26 versus 2.43). The same result was observed in the rates of some diagnostic groups. CONCLUSIONS: Primary care doctors can achieve a high degree of quality in ICD-9-CM diagnosis coding. Implementing procedures for evaluating coding, rectifying mistakes, and providing information to physicians markedly improved the initial results. 相似文献

We investigated the influence of the patient's gender for diagnostic and therapeutic approach of physicians at the outpatient clinic of the university hospital of Basle. In a prospective study 13 male residents in their second and third year of medical training were observed in their management of 25 female and 25 male patients presenting with the leading complaint of abdominal pain with regard to taking of the medical history, the physical examination and the performed diagnostic and therapeutic procedures, without informing the participating physicians. The time spent for the first consultation and the number of follow ups performed were registered. Following differences in the management of female and male patients were observed: The time spent at the first consultation was 59 +/- 5 minutes in female and 45 +/- 3.5 in male patients (p less than 0.03). Fundoscopic examination was three times more often performed in female patients. Endoscopic examinations were more often observed in male patients (p less than 0.01). Antacids and H2-antagonists were more frequently prescribed in male (p less than 0.01). Spasmolytics and laxatives more frequently in female (p less than 0.01). In summary in male patients the diagnosis of functional disease was predominantly made after exclusion of an organic disease what does explain the use of more diagnostic procedures and the induction of a more specific therapy. 相似文献

Data on diagnostic imaging procedures from a highly structured interview were compared to medical records in a case-control study of radiography and acute myelogenous leukemia. Three hundred and twenty-eight cases and 315 controls (78% of participants) had medical records available from an average of 71% of providers. Proxies were used for 49% of cases because of rapid fatality. Mean agreement (number of procedures in medical records subtracted from number in interview) showed similar levels of overreporting in cases [0.6; 95% confidence interval (CI): 0.0, 1.1] and controls (0.7; CI: 0.2, 1.3) with few procedures (<= 10). Most participants with more procedures underreported exposure, and underreporting increased with increasing exposure, especially among cases [mean (CI) agreement = -2.1 (-4.3, 0.0) for 11-20 procedures, -6.4 (-13.6, 0.7) for >20 procedures] and case proxies. High-dose, fluoroscopic, and non-routine procedures were self-reported more accurately than low-dose, non-fluoroscopic, and routine procedures, respectively (p < 0.01 for each comparison), and tended to be underreported. Case-control differences in agreement were non-significant for these categories of procedures. We conclude that diagnostic imaging procedures of most interest to the AML-radiography hypothesis are self-reported accurately but that underreporting does occur and might lead to attenuated risk estimates. 相似文献

BACKGROUND: Previous studies have reported variation in the population-based use rate of diagnostic and therapeutic procedures. Cholecystectomy is one of the most common surgical procedures, and we conducted this study to assess whether in Israel the use of this procedure varied by region and whether differences in use can be related to differences in appropriateness of use. In Israel, there is a pre-paid health insurance system and all surgeons are salaried. METHODS: Age-adjusted rates of cholecystectomy in four hospitals, each serving a defined population in Israel, were calculated. Two hundred and sixty-six potential clinical indications for performing cholecystectomy were rated as to their appropriateness by a panel of 9 expert physicians. A trained team abstracted the medical records of all patients who underwent the operation in the four Israeli hospitals in 1986 (n = 702) and recorded the clinical indication for the surgery. RESULTS: The population-based age-adjusted rates of cholecystectomy varied over threefold among the four hospitals. 29% of the cholecystectomies were performed for less than appropriate reasons, and this figure varied by hospital from 36% to 17% (p = 0.002). However, appropriateness did not vary systematically with the population-based use rate. CONCLUSION: Cholecystectomy was performed frequently for inappropriate or equivocal reasons, even in a country in which resources are limited, and physicians are salaried. Efforts to improve surgical decision making should be undertaken. 相似文献

Quality of morbidity coding in general practice computerized medical records: a systematic review 总被引:7,自引:0,他引:7
BACKGROUND: Increased use of computers and morbidity coding in primary care delivery and research brings a need for evidence of the quality of general practice medical records. OBJECTIVE: Our aim was to assess the quality, in terms of completeness and correctness, of morbidity coding in computerized general practice records through a systematic review. METHODS: Published studies were identified by searches of electronic databases and citations of collected papers. Assessment of each article was made by two independent observers and discrepancies resolved by consensus. Studies were reviewed qualitatively due to their heterogeneity. RESULTS: Twenty-four studies met the inclusion criteria for the review. There was variation in the methodology and quality of studies, and problems in generalizability. Studies have attempted to assess the completeness and correctness of morbidity registers by reference to a gold standard such as paper notes, prescribing information or diagnostic tests and procedures, each of which has problems. A consistent finding was that quality of recording varied between morbidities. One reason for this may be in distinctiveness of diagnosis (e.g. coding of diabetes tended to be of higher quality than coding of asthma). CONCLUSIONS: This review highlights the problems faced in assessing the completeness and correctness of computerized general practice medical records. However, it also suggests that a high quality of coding can be achieved. The focus should now be on methods to encourage and help practices improve the quality of their coding. 相似文献

INTRODUCTION: To increase data reliability and reduce the costs associated with the HTR, the Catalan Institute of Oncology programmed the manual procedures of data collection from databases by means of a computer application (ASEDAT). MATERIAL AND METHOD: ASEDAT detects the incident tumors of the registry from the databases of the pathology records (PR) and discharge records (DR) and selects the basic information from both databases. Data from the HTR data was collected for the period 1999-2000 by means of 2 procedures: manual and automatized collection and the results obtained were compared. RESULTS: 10,498 cancer patients were detected. Manual resolution detected 8,309 incident tumors and 2,374 prevalent tumors. ASEDAT automatically detected 8,901 patients (84.8%), in whom 8,367 incident tumors were detected (58 more tumors than the manual procedure). Validation of agreement was performed in the incident tumors detected by both methods (7,063 tumors). In 6,185 tumors (87.6%) the information agreed in all the variables. Of the discordant tumors, 692 (9.8%) were obtained by the RHT staff using manual resolution, and the remainder (186; 2.6%) were obtained by the application (automatic resolution). CONCLUSIONS: Cancer registry automatization is feasible when PR and DR databases are available, coded and automatized. 相似文献

OBJECTIVE: To determine the clean surgical wound infection rate for breast procedures and the risk factors predisposing patients to these infections. DESIGN: A survey study. SETTING: Oncology center. PATIENTS: A consecutive sample of adult female patients who underwent surgical breast procedures for suspected carcinoma of the breast. Patients undergoing excisional biopsy, lumpectomy, or mastectomy from January 1985 to January 1987 were included in the study. INTERVENTION: Clean surgical wound infection rates were derived overall and for each procedure type. The medical records of all patients were then reviewed to extract data on patient characteristics and operative information in order to assess the risk factors for infection. RESULTS: Among the breast procedures performed on 448 patients, the overall clean surgical wound infection rate was 8.7% (39/448). The clean surgical wound infection rate for each procedure type was as follows: biopsy 2.3%, lumpectomy 6.6%, and mastectomy 19%. In addition to the type of procedure, factors significantly (p less than .05) associated with the development of clean surgical wound infection in the univariate analysis included: presence of surgical drains (p less than .01); closed suction drainage (odds ratio [OR] = 16.5, 95% confidence interval [CI95] = 5.0-54.7); location of the drain (OR = 3.3, CI95 = 1.7-6.6); prolonged preoperative stay (OR = 1.2, CI95 = 1.0-1.5); length of surgery (OR = 2.2, CI95 = 1.7-3.0); and greater mean age (OR = 1.6, CI95 = 1.2-2.1). CONCLUSION: Clean surgical wound infections are not uncommon in patients undergoing breast procedures. Factors relating to both the patient and operative techniques contribute to the clean surgical wound infection rate. Further consideration should be given to perioperative antibiotic prophylaxis for selected breast procedures, and the role of surgical drains should be reassessed. 相似文献

OBJECTIVE: To examine the reliability of the data produced by an automated system for the surveillance of nosocomial infections. SETTING: A 906-bed, tertiary-care teaching hospital. DESIGN: Three surveillance techniques were concurrently performed in seven high-risk units during an 11-week period: automated surveillance (AS) based on the prospective processing of computerized medical records; laboratory-based ward surveillance (LBWS) based on the retrospective verification by ward clinicians of weekly reports of positive bacteriologic results; and a reference standard (RS) consisting of the infection control team reviewing case records of patients with positive bacteriology results. Bacteremia, urinary tract infections, and catheter-related infections were recorded for all inpatients. The performances (sensitivity, specificity, and time consumption) of AS and LBWS were compared with those of RS. RESULTS: Of 548 positive bacteriology samples included during the study period, 229 (42%) were classified as nosocomial infections. The overall sensitivity was 91% and 59% for AS and LBWS, respectively. The two methods had the same overall specificity value (91%). Kappa measures of agreement were 0.81 and 0.54 for AS and LBWS, respectively. AS required less time to collect data (54 seconds per week per unit) compared with LBWS (7 minutes and 43 seconds per week per unit) and RS (37 minutes and 15 seconds per week per unit). CONCLUSION: Our results confirm that the retrospective review of charts and laboratory data by physicians lacks sensitivity for the surveillance of nosocomial infections. The intranet-based automated method developed for this purpose was more accurate and less time-consuming than the weekly, retrospective LBWS method. 相似文献

The retained surgical sponge seems to be an ongoing problem. Despite the fact that reports of retained surgical sponges are comparatively rare, this problem seems to be more prevalent than is generally appreciated. Even though counting sponges is a tedious task, it should nonetheless be performed with the utmost attention. Although the presence of radiopaque wires in the sponges is helpful in locating these, it does not prevent surgical sponges from being forgotten. These retained sponges can result in serious conditions such as septic complications or pseudo-tumour formation, which in turn might lead to extensive diagnostic and secondary surgical procedures. 相似文献

OBJECTIVE: In November 1998, Oregon voters passed Ballot Measure 58, which allowed Oregon adoptees > or = 21 years of age access to their original birth records, which are sealed at adoption. The objective of this study was to evaluate the impact of the measure on the Oregon Health Division (since renamed Oregon Health Services) by assessing procedures used and resources needed after implementation of Measure 58. METHODS: Vital records employees were interviewed about processing, storage, and archive retrieval procedures for pre-adoption birth records before, during, and after the implementation of Measure 58 and the effect on their usual workload. Personnel time, space, and fiscal resources used to process requests for pre-adoption records were also calculated. RESULTS: The Oregon Health Division began to receive requests from adoptees immediately following the passage of Measure 58 in November 1998, but due to legal challenges, they could not be processed until May 31, 2000. From June 2, 2000, through October 20, 2000, 12 staff members and two supervisors issued more than 4,700 pre-adoption birth records while also processing their normal workload, which averages more than 135,400 vital record orders annually. Due to the need for retrieval from archives, requests for pre-adoption birth records were estimated to take 75 hours to process vs. 2-3 minutes for standard requests. Each batch of approximately 75 pre-adoption birth records required approximately 12.5 person-hours from vital records staff and 3-4 person-hours from archive personnel; in addition, supervisors spent time responding to incomplete orders, informing the public and the media, and responding to concerns of adoptees, birth parents, and adoptive parents. Fewer than 1% of requests went unfilled. CONCLUSIONS: Implementation of Measure 58 utilized substantial resources of the Oregon Health Division. States contemplating similar legislation should consider increasing personnel and resources, preparing for intense public and media interest, and reorganizing the storage of adoptees' original birth records so they are easily retrieved. 相似文献

Objective: To determine whether sterilising procedures — hysterectomies, endometrial ablations or tubal ligations — are being performed in minors for non-therapeutic reasons, without Family Law Court approval.
Methods: Victorian Admitted Episode Dataset 1996–99 was used to identify all young women < 18 who had a sterilising procedure. Associated codes for indications and pathology were reviewed to exclude malignancies, congenital anomalies, potential miscoding and misleading codes associated with endometriosis.
Results: Although 40 procedures were identified from the dataset, the majority of these can be excluded after review of the associated codes. In two cases sterilising procedures were performed without clear therapeutic indications and it is likely they were done in young women with disabilities. No Family Law Court applications were heard in this time period, thus it is likely they represent unlawful sterilisations.
Conclusions: It would appear that sterilisations without Family Law Court approval are probably occurring at very low rates in Victoria. 相似文献
