Developing a template matching algorithm for benchmarking hospital performance in a diverse, integrated healthcare system.

Template matching is a proposed approach for hospital benchmarking, which measures performance based on matching a subset of comparable patient hospitalizations from each hospital. We assessed the ability to create the required matched samples and thus the feasibility of template matching to benchmark hospital performance in a diverse healthcare system.Nationwide Veterans Affairs (VA) hospitals, 2017.Observational cohort study.We used administrative and clinical data from 668,592 hospitalizations at 134 VA hospitals in 2017. A standardized template of 300 hospitalizations was selected, and then 300 hospitalizations were matched to the template from each hospital.There was substantial case-mix variation across VA hospitals, which persisted after excluding small hospitals, hospitals with primarily psychiatric admissions, and hospitalizations for rare diagnoses. Median age ranged from 57 to 75 years across hospitals; percent surgical admissions ranged from 0.0% to 21.0%; percent of admissions through the emergency department, 0.1% to 98.7%; and percent Hispanic patients, 0.2% to 93.3%. Characteristics for which there was substantial variation across hospitals could not be balanced with any matching algorithm tested. Although most other variables could be balanced, we were unable to identify a matching algorithm that balanced more than ∼20 variables simultaneously.We were unable to identify a template matching approach that could balance hospitals on all measured characteristics potentially important to benchmarking. Given the magnitude of case-mix variation across VA hospitals, a single template is likely not feasible for general hospital benchmarking.

Emergency general surgery in the United Kingdom: A lot of general, not many emergencies, and not much surgery.

BACKGROUND: The provision of emergency general surgery services is a global issue, with important implications for patients and workforce. The aim of this study was to analyze the characteristics of emergency general surgical patients in the United Kingdom, with reference to diagnostic case mix, operative workload, comorbidity, discharge destination, and outcomes, to facilitate comparisons and future service development. METHODS: This is a cross-sectional population-based study based in the National Health Service in Scotland, one of the home nations of the United Kingdom. All patients aged 16 or older admitted under the care of a general surgeon, as an emergency, to a National Health Service hospital in Scotland, in 2016, were included. RESULTS: There were 81,446 emergency general surgery admissions by 66,498 patients. Median episode age was 53 years. There were more female patients than male (55% vs 45%, p < 0.0001). The most common diagnoses were nonspecific abdominal pain (20.2%), cholecystitis (7.2%), constipation (3.4%), pancreatitis (3.1%), diverticular disease (3.1%), and appendicitis (3.1%). Only 25% of patients had operations (n = 20,292). The most frequent procedures were appendicectomy (13.1%), endoscopy (11.3%), and drainage of skin lesions (9.7%). Diagnoses and operations differed with age. Overall median length of stay was 1 day. With a 6-month follow-up, patients older than 75 years had a 19.8% mortality rate. CONCLUSIONS: Emergency general surgery in the United Kingdom is a high-volume, diagnostically diverse, and low-operative volume specialty with high short-term mortality rate in elderly patients. Consideration should be given to alternative service delivery models, which make better use of surgeons' skills while also ensuring optimal care for patients who are increasingly elderly and have complex chronic health problems. LEVEL OF EVIDENCE: Epidemiologic study, level III.

[Geriatrics or geriatricization of medicine : Quo vadis geriatrics?] / Geriatrie oder Geriatrisierung der Medizin : Quo vadis Geriatrie?

This article examines the question whether and how geriatrics will change in the future and whether in view of the demographic changes the trend will go more in the direction of a further expansion of geriatrics or more towards a geriatricization of individual specialist medical fields. The different development of geriatrics in the individual Federal States can only be understood historically and is absolutely problematic against the background of the new hospital remuneration system. Geriatrics is a typical cross-sectional faculty and still has demarcation problems with other faculties but has also not yet clearly defined the core competence. This certainly includes the increasing acquisition of decentralized joint treatment concepts and geriatric counselling services in the future, in addition to the classical assessment instruments. Keywords in association with this are: traumatology and othopedics of the elderly, geriatric neurology and geriatric oncology. Interdisciplinary geriatric expertise is increasingly being requested. Outpatient structures have so far not been prioritized in geriatrics. An independent research is under construction and it is gratifying that academic interest in geriatrics seems to be increasing and new professorial chairs have been established. It is not possible to imagine our hospital without geriatrics; however, there is still a certain imbalance between the clearly increased number of geriatric hospital beds, the representation of geriatrics in large hospitals (e.g. specialized and maximum care hospitals and university clinics), the secure establishment in further education regulations and the lack of a uniform nationwide concept of geriatrics.

[Formation of centers in general and abdominal surgery -- necessity or trend?]. / Zentrenbildung in der Allgemein- und Viszeralchirurgie - Notwendigkeit oder Trend?

The introduction of the DRG (diagnosis-related groups) system as basis for reimbursement in the German health-care system has led to a mentality of quality orientation and verification of therapeutic results. An immediate result was the formation of medical "centres" on rather different levels and consequently the inauguration of institutions, authorities, and organisations to review these centres. Finally, a range of certifications was installed in order to stratify the rather diverse aims of different centres. This review critically evaluates the current situation in the field of general and abdominal surgery in Germany.

[Experiences from more than 2,100 hernia repair operations. How has the therapy changed in the last 15 years?]. / Erfahrungen aus über 2100 Hernienreparationen. Wie hat sich die Therapie in den letzten 15 Jahren verändert?

INTRODUCTION: Inguinal hernia (IH) surgery has changed fundamentally during the last 25 years due to tension-free repair, minimally-invasive approaches and growing influence of economy in medical decision making. Aim of the study was the documentation and analysis of changes in IH surgery during the last 15 years in our patient cohort. MATERIAL AND METHODS: Patients undergoing elective or emergency inguinal/femoral hernia repair from January 1995 to December 2009 were included in the study. Analysis of patient data was carried out by prospective online recording. RESULTS: A total of 1,908 patients with 2,124 IHs were treated in the study period and the number of IH repairs decreased continuously. The number of recurrent hernias peaked in 2005-2009 with 16.4%. The average preoperative hospital stay decreased from 2.4 to 0.4 days and the postoperative hospital stay from 7.0 to 3.3 days. The percentage of suture repairs declined from 54.9% in 1995 to 4.1% in 2009 and the percentage of open tension-free repairs rose to 52.9% in 1998. In the following years the majority of repairs were performed by minimally invasive procedures but in 2009 the percentage of conventional hernia repairs exceeded the rate of minimally invasive repairs. CONCLUSION: The main reason for these changes is the implementation of diagnosis-related groups which hampers inpatient repair of "simple" inguinal hernias, favors short hospital stay and does not adequately reimburse minimally invasive repairs.

Current trends in the length of stay in neurological early rehabilitation.

BACKGROUND: Neurological early rehabilitation (phase B) is an integral component of the phase model of the German Federal Rehabilitation Council (Bundesarbeitsgemeinschaft für Rehabilitation, BAR). We studied the current trend in patients' length of stay. METHODS: This study included 2060 cases of the BDH-Klinik Hessisch Oldendorf (a neurological rehabilitation clinic) from 2005 to 2008 that fulfilled the structural characteristics of item 8-552 of the German coding system for operations and procedures (Operationen- und Prozedurenschlüssel, OPS), which codes for neurological and neurosurgical early rehabilitation. We studied the parameters age, sex, length of stay, type of discharge, diagnoses, and morbidity. 75.7% of the collective carried a diagnosis of cerebral ischemia, traumatic brain injury, or intracerebral hemorrhage. RESULTS: The mean length of stay over the entire period of the study was 44.6 days. A successive reduction of the mean length of stay from 2005 to 2008 was evident, from 46.8 days in 2005 to 37.5 in 2008 (p<0.001). The morbidity, too, declined over the period of the study. 76.4% of the cases analyzed stayed in hospital for at least the minimum of 8 weeks proposed by the BAR. 39.5% of the patients improved to such an extent in phase B that they were able to be transferred to a further rehabilitation facility, while about one patient in five was transferred from early rehabilitation to a nursing facility. The mortality was 0.9%. Although the early rehabilitation procedure was correctly coded, a total of 60 different diagnosis-related groups (DRGs) were applied. CONCLUSION: These data support the BAR's recommendation for a minimum length of stay of 8 weeks in phase B. The observed shortening of the length of stay was found to be primarily the result of a reduction in morbidity during early rehabilitation. This, in turn, may well be due to a selection effect of the early rehabilitation procedure code 8-552.

[Surgery on the fast track--"fast track" concepts in abdominal-/pediatric surgery and urology]. / Operative Medizin auf der Schnell- oder Uberholspur--"Fast Track" Konzepte in Chirurgie, Kinderchirurgie und Urologie.

In surgical medicine there are traditions, myths, rites and dogmas which define concepts of treatment and strategies. Upheld and passed on without being examined or confirmed in further studies, these concepts and strategies include preoperative intestinal lavage and fasting, postoperative long-term drainage, tubes und catheters, long-term relaxation of the intestine after abdominal surgery or immobilisation for some days. New techniques and procedures in surgery and anaesthesia, including postoperative pain management like laparoscopic surgery and partial anaesthesia, reduce the need for surgery and minimize morbidity of treatment. For more than ten years now, the Copenhagen abdominal surgeon Henrik Kehlet and his team have systematically dealt with the question of how to reduce perioperative stress and improve postoperative conditions of recovery. The resulting concepts of an "enhanced recovery after surgery" (ERAS) seek to overcome handed-down myths und fix new clinical pathways. In current prospective studies of elective surgery, the clinical use of these fast track concepts have been confirmed in colon surgery, pediatric surgery and urology. Here, examples of some of these studies are discussed together with problems like general complications and length of stay, while aspects of insurance are also taken into consideration.

[Changes in the G-DRG System from 2003 to 2005 in Ophthalmology--Ophthalmologic G-DRG 2003 to 2005]. / Anderungen des G-DRG-Systems von 2003 bis 2005 in der Augenheilkunde -- Ophthalmologische G-DRGs von 2003 bis 2005.

BACKGROUND: The objective of the study was to illustrate the effect of the extensive changes of the German DRG System on reimbursement of clinical ophthalmology during the years 2003, 2004 and 2005. METHODS: All ophthalmologic patients treated as in-patients at the Department of Ophthalmology at the University Munich during the year 2003 served as a reference data basis. By means of appropriate software those cases were then re-grouped according to the G-DRG classification of the years 2003, 2004 and 2005. This resulted in different reimbursements caused only by system changes for an exemplary hospital of maximum medical care. In addition, the same calculations were performed for four virtual, typical clinics based on the calculation data of the "Institut für Entgeltsysteme (InEK)". For those four clinics it was assumed that 80 % of the cases came from one of the subspecialties retina, glaucoma, cataract or strabismus surgery. RESULTS: Changes in the G-DRG system caused the sample hospital of maximum care to loose 8.5 % case mix index (CMI) during the period of 2003 to 2005. For three of the four virtual, typical ophthalmological clinics the theoretic reimbursement conditions also deteriorated: retina surgery -- 10.6 %, glaucoma surgery - 15.8 % and cataract surgery -- 17.9 % CMI. Only strabismus surgery showed an increase of + 5.6 % in CMI during the period examined. CONCLUSION: Over the years 2003 to 2005 the CMI clearly deteriorated for many ophthalmological subspecialties given otherwise identical conditions. To calculate the changes specifically for an individual hospital, the individual base rates have to be considered.

[Cardiovascular medicine in the updated German diagnosis-related groups (G-DRG) for the year 2004]. / Abbildung der Herz-Kreislauf-Medizin im deutschen Fallpauschalen-(G-DRG)-System 2004.

Based on the medical and economical data of 137 German hospitals including 12 university hospitals, the Institut für das Entgeltsystem im Krankenhaus (InEK) was again authorized by the German Ministry of Health to calculate and develop a refined version of the German diagnosis related groups (G-DRG) for the year 2004. The catalogue of these updated GDRGs was published on October 15' 2003. Furthermore, the grouper programs containing the current algorithms and the cost data on which the new G-DRGs were based have been published in the last few weeks. With regard to cardiovascular DRGs, a number of changes have been introduced in the G-DRG system which have profound consequences for all departments that treat patients with these diseases. In this review, we want to present in detail the key points of this update concerning the DRGs, extra reimbursement for special interventions, and new codes for diagnoses and procedures. Furthermore, the new rules for readmissions of patients in the same hospital are summarized. In conclusion, a number of improvements have been implemented in the updated G-DRG system which had in part been suggested by several national medical societies. These provide the basis for more precise and detailed DRGs but require on the other hand, a precise and complete coding to allow correct grouping procedures. From an economical point of view, it could hardly be summarized whether these improvements would lead to an adequate reimbursement for the treatment costs of patients with cardiovascular diseases since the case-mix of the various departments may vary widely.

[Suggestions for implementation of DRG in the fields of Orthopaedics and Trauma Surgery for 2004]. / DRG-Anpassungsvorschläge der Fachgebiete Orthopädie und Unfallchirurgie für 2004.

OBJECTIVE: The Implementation of a DRG-Variant in Germany - voluntarily since January 1 st, 2003 and obligatory from January 1 st, 2004 - has been leading to uncertainty, particularly in the hospitals, due to fears that currently practised German diagnostic and therapeutic measures will not be financed properly by a DRG-Variant. The G-DRG-Version 1.0 that was drawn up in connection with an executive order law is to a large degree identical to the Australian AR-DRG-Version 4.1. Adjustments to German requirements were made only marginally. Therefore it is necessary for every medical field to investigate by stock-taking to what extent currently practised German diagnostic and therapeutic measures are considered in the G-DRG-Version 1.0 and whether and where modifications and adaptations need to be made. In order to make qualified statements scientific evaluations of possible problems have to be made based German data. Therefore an evaluation was made of the mapping of the medical fields of orthopaedics and trauma surgery. The German Society of Trauma Surgery (DGU), the German Society of Orthopaedy and Orthopaedic Surgery (DGOOC) in cooperation with the DRG-Research-Group of the University Hospital Muenster, the German Hospital Federation (DKG) and the German Medical Association carried out a DRG evaluation project in order to investigate the medical and economical homogeneity of the case groups. METHOD: 12,645 orthopaedic and trauma surgery cases from 23 hospitals - 11 university hospitals and 12 non-university hospitals - were collected within an period of three months and were scientifically evaluated with regard to their performance homogeneity and length of stay homogeneity. RESULTS: The data formed the basis for the proof of suspected deficiencies of mapping of orthopaedic and trauma surgery cases within the G-DRG-Variant. Based on the data and additionally on conclusions of medical experts when the number of cases were small, 14 suggestions for adaptation were proposed and submitted by the deadline of March 31 st, 2003 to the InEK. CONCLUSION: The results of the DRG-Evaluation Project demonstrate the problems of mapping the very heterogenous and complex medical performances of orthopaedy and trauma surgery to a flat rate financing system that is not adapted properly to German conditions. The G-DRG-Variant Version 1.0 does not offer the sufficient possibilities of differentiation that are needed to map the various orthopaedical and trauma surgical measures in Germany.

[Knowledge management in rehabilitation--proposal for a systematic development of clinical practice guidelines]. / Wissensmanagement in der Rehabilitation - Vorschlag zu einer systematischen Entwicklung von Leitlinien.

In the past ten years, the German pension scheme has launched several initiatives that can be regarded as milestones on the way to a scientifically founded rehabilitation system. These initiatives were: the Rehab Commission (1989 - 1991), the Quality Assurance Programme (since 1994), and the German Research Funding Programme "Rehabilitation Sciences" (in cooperation with the Federal Ministry for Education and Research, since 1996). As a next step on this way, we propose an initiative aiming at a systematic development and implementation of clinical practice guidelines for the main diagnostic groups in rehabilitation. Guidelines for diagnostic and therapeutic decisions are an instrument to sift through the abundance of fast changing knowledge in medicine, to assess the existing knowledge according to its scientific evidence, and to transform it into recommendations for clinical practice. In rehabilitation, guidelines seem to be particularly needed because specialized knowledge is mostly disseminated through an informal "training on the job". Our proposal intends to establish a reference centre for each of the main indications (cardiology, musculoskeletal diseases, etc.). These centres should cooperate with experts from clinical practice and research, as well as with representatives of the cost-carrying agencies and patient organisations, and should systematically analyse the processes of rehabilitation in the most important diagnostic groups. Guided by a "process matrix of rehabilitation", these analyses should identify the points at which far-reaching decisions are called for during the processes of rehabilitation. At these points, the knowledge base available for rational decisions should be examined. When there is no sufficient scientific knowledge, consensus conferences should be organized in order to collect and assess the available expertise of practitioners and to establish guidelines for clinical practice. Since compliance with such guidelines could be easily checked in the routine quality assurance programme, this proposal seems to be a promising way of improving the knowledge base in rehabilitation in a rather short time.

Measuring the unmeasurable: a caring science perspective on patient classification.

AIMS: To give a short historical survey of patient classification and its motives, to analyse patient classification and especially the instrument, The Oulu Patient Classification more closely from a caring science perspective. BACKGROUND: A survey of topical literature and research on patient classification show that economic and administrative justifications predominate and the caring science connection is weak, almost non-existent. ORIGINS OF INFORMATION: Topical literature and research on patient classification and the instrument, The Oulu Patient Classification. DATA ANALYSIS: Topical literature and research were evaluated from a caring science perspective in accordance with Eriksson's theory of caring and the basic concept of man as an entity of body, soul and spirit. KEY ISSUES: Patient classification is used in staff planning and is also justified from the viewpoint of content, that is, as a method of guaranteeing good quality in the care of patients and as an expression of the prevalent caring ideology. The concept of man is reduced in current literature and research on patient classification. The Oulu Patient Classification is based on a humanistic view of man, but man's spiritual and existential needs do not emerge clearly from the manual of the instrument. CONCLUSIONS: It is essential for patient classification to start from a caring perspective. Correctly dimensioned staffing based on patient classification is a prerequisite for good care. This should be combined with a caring culture that considers the whole complexity of man in order to make good care possible.
