On the use of administrative databases to support planning activities: the case of the evaluation of neonatal case-mix in the Emilia-Romagna region using DRG and APR-DRG classification systems.

There are several versions of the Diagnosis Related Group (DRG) classification systems that are used for case-mix analysis, utilization review, prospective payment, and planning applications. The objective of this study was to assess the adequacy of two of these DRG systems--Medicare DRG and All Patient Refined DRG--to classify neonatal patients. The first part of the paper contains a descriptive analysis that outlines the major differences between the two systems in terms of classification logic and variables used in the assignment process. The second part examines the statistical performance of each system on the basis of the administrative data collected in all public hospitals of the Emilia-Romagna region relating to neonates discharged in 1997 and 1998. The Medicare DRG are less developed in terms of classification structure and yield a poorer statistical performance in terms of reduction in variance for length of stay. This is important because, for specific areas, a more refined system can prove useful at regional level to remove systematic biases in the measurement of case-mix due to the structural characteristics of the Medicare DRGs classification system.

Continuous training as a key to increase the accuracy of administrative data.

The aim of this study was to evaluate the impact of a program of training, education and awareness on the accuracy of the data collected from hospital discharge abstracts. Four random samples of hospital discharge abstracts relating to four different periods were studied. The evaluation of the impact of systematic training and education activities was performed by checking the quality of abstracting information from the medical records. The analysis was carried out at the Istituto Dermopatico dell'Immacolata, a research hospital (335 beds) in Rome, Italy, which specializes in dermatology, plastic and vascular surgery. Error rates in discharge abstracts were subdivided into six categories: selection of the wrong principal diagnosis (type A); low specificity of the principal diagnosis (type B); incomplete reporting of secondary diagnoses (type C); selection of the wrong principal procedure (type D); low specificity of the principal procedure (type E); incomplete reporting of procedures (type F). A specific rate for errors modifying classification in diagnosis related groups (DRG) was then estimated and the effect of re-abstracting on the case-mix index evaluated. Error types A, B, C, E and F dropped from 8.5% to 2%, 15.8 to 4.9, 31.8 to 13.1,4.1 to 0.3 and 22 to 2.6%, respectively. Error type D was 0.7 both in the first (the baseline) and fourth periods of analysis. All differences in error types were statistically significant. In 1999 8.3% of cases were assigned to a different DRG after re-abstracting as compared with 24.3% in the third quarter of 1994, 23.8% in the first quarter of 1995 and 5.5% in September-October 1997. Continuous training and feedback of information to departments have shown to be successful in improving the quality of abstracting information at patient level from the medical record. These positive results were facilitated by the introduction of a prospective payment system to finance inpatient hospital activity. The effort to increase administrative data quality at hospital level facilitates the use of those data sets for internal quality management activities.

[Characteristics of voluntarily discharged patients: some reflections and a proposal]. / Caratteristiche dei pazienti con dimissione volontaria dall'ospedale: alcune riflessioni ed una proposta.

This study compares the characteristics of 492 patients discharged against medical advice from the Istituto Dermopatico dell'Immacolata, a Research Hospital (335 beds) in Rome specialized in Dermatology, Vascular Surgery and Plastic Surgery between 1995 and 1998, with those of 43,110 control patients discharged with physicians' approval according to a case-control model. In the multivariate analysis, male gender (OR 1.65; 95% CI 1.37-1.98) and residence in Rome area (OR 1.22; 95% CI 1.02-1.47) increased the odds of discharge against medical advice. The odds of such discharge decreased with increasing age (OR 0.994 per year; 95% CI 0.990-0.999). The proportion of patients discharged against medical advice decreased from 1.4% in 1995 to 0.4% in 1998. The average length of stay decreased from 1995 to 1998, with the exception of the Plastic Surgery unit. A retrospective review of the charts of 45 patients discharged against medical advice (AMA) within 48 hours from admission ascertained some of the stated reasons for discharge. Personal and family problems or refusal of treatment were reported for 35% of the patients. Of the 25 patients who gave no reasons, 11 asked again for hospitalization and 5 of these were rehospitalized by IDI within 10 days. This study also identified that the information on the medical record of patients who left against medical advice was generally poor. A standardized form for AMA discharges, including patient's understanding of the diagnosis, treatment, alternative therapies, consequences of refusing treatment and stated reasons for leaving against medical advice, might be of benefit to patients, physicians and hospital managers.

[Social class, mode of admission, severity of illness and hospital mortality: an analysis with "All patient refined DRG" of discharges from the Molinette hospital in Turin]. / Classe sociale, modalità di ricovero, gravità clinica e mortalità ospedaliera: un'analisi con "All Patient Refined--DRG" dei dimessi dall'ospedale Molinette di Torino.

Data available from the standard hospital discharge database (SDO) allow us to explore differences in health conditions according to different indicators of socioeconomic status (SES). We analysed all the patients aged 30-59, discharged from the S. Giovanni Battista (Molinette) hospital (the main general hospital in Turin, Italy) during three years (1996-1998) (n = 49949). Three health indicators were used as outcomes: a) emergency admission; b) severity of illness (according to the "All Patient Refined DRGs" subclasses); c) hospital mortality. Patients were compared for each outcome according to two different SES indicators: a) level of education; b) employment status. Logistic regression models (both conditional and unconditional) were used to adjust for several potential confounders. Patients with lower education (up to 5 years of schooling), compared to those with 13 or more years of schooling, showed a higher probability of being admitted through the emergency ward (29.1% vs 23.3%), with an odds ratio (OR) = 1.56-95% confidence interval (95% CI) = 1.45-1.68; of being classified in higher severity subclasses of illness (23.3% vs 17.7%, OR = 1.14; 95% CI = 1.07-1.22) and of dying in hospital (2.3% vs 1.6%). However, after adjustment for other prognostic factors (as severity of illness and specific expected mortality), this association disappeared (OR = 1.05, 95% CI = 0.84-1.32). Similar, but somewhat stronger, associations were observed when comparing the unemployed versus the employed. The corresponding figures (ORs; 95% CI) were 1.57 (1.42-1.74) for emergency admission; 1.31 (1.18-1.45) for severity of illness and 1.55 (1.10-2.16) for hospital mortality. In conclusion, this study showed that SES differentials in health are clearly measurable through routine hospital information systems, and documented that patients of low SES, particularly unemployed, experienced a delayed access to hospital, were admitted in poorer general health conditions and had a more unfavourable prognosis.

The quality of abstracting medical information from the medical record: the impact of training programmes.

OBJECTIVE: To evaluate the impact of a programme of training, education and awareness on the quality of the data collected through discharge abstracts. STUDY DESIGN: Three random samples of hospital discharge abstracts relating to three different periods were studied. Quality control to evaluate the impact of systematic training and education activities was performed by checking the quality of abstracting medical records. SETTING: The study was carried out at the Istituto Dermopatico dell'Immacolata, a research hospital in Rome, Italy; it has 335 beds specializing in dermatology and vascular surgery. MEASURES: Error rates in discharge abstracts were subdivided into six categories: wrong selection of the principal diagnosis (type A); low specificity of the principal diagnosis (type B); incomplete reporting of secondary diagnoses (type C); wrong selection of the principal procedure (type D); low specificity of the principal procedure (type E); incomplete reporting of procedures (type F). A specific rate of errors modifying classification in diagnosis related groups was then estimated. RESULTS: Error types A, B and F dropped from 8.5% to 1.3%, from 15.8% to 1.6% and from 22% to 2.6% respectively. Error type D and E were zero in the third period of analysis (September-October 1997) compared with a rate of 0.7% and 4.1% in the third quarter of 1994. Error type C showed a slight decrease from 31.8% in 1994 to 27.2% in 1997. All differences in error types except incomplete reporting of secondary diagnoses were statistically significant. Five and a half per cent of cases were assigned to a different diagnoses related group after re-abstracting in 1997 as compared to 24.3% in the third quarter of 1994 and 23.8% in the first quarter of 1995. DISCUSSION: Training and continuous monitoring, and feedback of information to departments have proved to be successful in improving the quality of abstracting information at patient level from the medical record. The effort to increase administrative data quality at hospital level will facilitate the use of those data sets for internal quality management activities and for population-based quality of care studies.

[Diabetic nephropathy and pregnancy]. / Nefropatia diabetica e gravidanza.

Diabetes mellitus (or type 1) is a long-lasting disease (even twenty years or more) which causes kidney disease and, in the event of pregnancy, it can make differential diagnostic difficult even fort the most expert clinician. Metabolic changes caused by this type of diabetes (e.g., hypoglycemia, hyperglycemia, ketoacidosis) and their difficult compensation can often lead to the onset of eclampsia or convulsion. The diagnostic suspicion of diabetes is supported by the finding of proteinuria, edema and hypertension that are strictly correlated with the evolution of diabetic disease and sometimes exist prior to pregnancy. This cas report focuses on the diagnostic importance of clotting tests, especially in clarifying diagnostic doubts.

An outbreak of hepatitis A in young adults in central Italy.

Between September, 1988 and January, 1989 a common source outbreak of 47 cases of serologically confirmed hepatitis A occurred in a town of central Italy. Thirty-eight cases were primary, three co-primary and six secondary. The highest age-specific attack rate was seen in subjects aged 15-24 years (120 per 100,000); the mean age of cases was 24.6 years and the median age was 22 years. A matched triplet case-control study showed significant association between the disease and consumption of either raw mussels (41% of cases, compared with 10% of controls; P less than 0.0001) or a single brand of mineral water (63% of cases, compared with 41% of controls; P less than 0.05). The mean age of the cases reflects the shift in primary susceptibility to the infection from younger to older age groups, a finding which has recently been demonstrated by several seroepidemiological surveys in Italy.

[Beta thalassemia: motivation for screening in Terni]. / Beta-talassemia: motivazione per uno screening a Terni.

There are no definitive data on the frequency of beta-thalassaemia in the Province of Terni; a mass screening programme has not been carried out. Preliminary studies confirm that there is a strong incidence of beta-thalassaemia heterozygotes. A theory can be put forward for the presence of beta-thalassaemia trait, based on the notion of the multicentric genesis of the disorder: the malaria may have been the dominant selective factor.

Cost analysis for rehabilitation services in Zimbabwe:a report prepared for the World Health Organisation

Like in most developing countries; there is paucity of cost data on the provision of rehabilitation services especially programme specific cost data in Zimbabwe. This study therefore endeavoured to test the WHO protocol on cost of heath services to cost rehabilitation services. The aim was to generate field information that would enable design of a protocol that can be effectively employed in other countries for costing rehabilitation services. The study is an economic study analysis of rehabilitation services which does not only look at financial costs but also social costs. An analysis of economics is a necessary pre requisite to the effective efficient expansion of rehabilitation services in Zimbabwe. Information on costs and possible simulations of changes in scale or organisational arrangements of community based rehablitation provides crucial baseline information for informed decision making
