[Hospital morbidity statistics: the accuracy of the diagnosis reported in the discharge registry book].

BACKGROUND: The registry book of admission and discharges (RBD) is operative in most public and private hospitals of this country. Currently its reformation is contemplated, consisting in a modification of the minimal set of basic data and its computerization. The aim of the present study was to evaluate the accuracy of the discharge diagnosis recorded in the RBD and to analyze the possible factors implicated in the current quality level. METHODS: In a sample of 9 hospitals from the Seville province, 2,634 discharges were selected with a stratified sampling process which was proportional to the number of discharges in each stratum during 1985. The accuracy of the diagnosis recorded in the RBD was estimated by comparing it with that in the clinical record (CR). RESULTS: The accuracy indexes showed that, for the large diagnostic groups, only in 45% of discharges the diagnosis coincided in both documents. The accuracy increased to 89% when the estimation was made after excluding those discharges where the diagnosis was not recorded in the RBD and/or in the CR (n = 1303). CONCLUSIONS: The fulfillment of the RBD appears as the main error source, followed by the selection of the major diagnosis and its transcription in the different documents of the circuit. It is concluded that a precondition for the success of a reformed RBD is to guarantee the fulfillment of data.

[Behavior of mortality indicators in small geographic areas: relative standardized mortality ratio and standardized proportional mortality ratio].

One of the most commonly used indicators in mortality studies is the Standardized Mortality Ratio (SMR) being the Relative Standardized Mortality Ratio (RSMR) an indicator of the relative magnitude of the SMR for a specific cause of death. Along with these indicators, which must be calculated by using the population at risk, there is the Standardized Proportional Mortality Ratio (SPMR), an indicator which measures the excess mortality referring to the proportional mortality established for a standard population. This paper reviews the theoretic conditions described in literature as being necessary to establish a probability interval for the RSMR centered on the SPMR as well as the correlations between both indicators and the use of the SPMR as a predictor of the RSMR. The results obtained clearly show how difficult it is for these theoretic conditions to exist. However, they do suggest that the SPMR be used as a predictor of RSMR.

[Multiple codification of the causes of death: from dying "of" to dying "from"].

Multiple-cause mortality data is examined in the Valencian Region. In addition to coding the underlying cause of death (UCD), all causes of death which appeared mentioned on death certificates (MCD) were coded according to preliminary rules established by the Mortality Statistics Office. Specific diseases were selected to explore mortality patterns. The average number of conditions coded per death certificate was 2.7. Two or more conditions on the lowest used line appeared in 33.8% of all medical certificates. Septicaemia, high blood pressure and arteriosclerosis stand out among the conditions more often coded as MCD than coded as UCD. Exploring for mortality patterns a statistical association between coronary heart disease and diabetes emerged (p less than 0.0001). Multiple-cause mortality coding allow to discriminate mortality patterns and show a new magnitude to some specific causes of death.

[An analysis of mortality in small areas: the problem of residency].

This study was designed to assess the influence of residence misclassification in small areas mortality analysis. Data from a health area in the Valencian Community, which has high mortality from coronary diseases (ICD410-414) has been used. Deaths occurred during 1988 (n = 190) have been divided, using the information reported in the Boletín Municipal de Defunción in two groups: with (n = 109) and without (n = 81) private residence in the area. The Standardized Mortality Ratio (SMR) for the studied diseases was 219.8 (CI 95%: 257.6; 182) for males and 174.8 (CI 95%: 218.7; 130.9) for females. When deaths of persons without residence in the area subtracted from the numerator a change in the SMRs is observed to 120.8 (CI 95%: 149.3; 92.3) in males and 135.9 (CI 95%: 175; 96.2) in females. The excess in coronary heart diseases observed in the area could be partially explained by the "Benidorm-Effect" produced by an important volume of foreign residents with a high risk of dying from these diseases which are not included in the area census.
