Life expectancy and mortality differences between populations on Croatian islands and the mainland.

AIM: To examine the differences in life expectancy and mortality between the populations on Croatian islands and the mainland, and among the islands themselves. METHOD: Data on population size and mortality collected in Croatia in 2001 were analyzed by life table and standardized mortality rates. RESULTS: Life expectancy at birth (95% confidence interval) of the population on Croatian islands was 76.4 yr (75.7-77.1) which was significantly higher than life expectancy at birth of general Croatian population which was 73.8 yr (73.5-73.9) or mainland Croatian population which was 73.7 yr (73.6-73.8). Island population had higher life expectancy until the age of 80 and again in the oldest age group, 95+. More than 10% of inhabited islands in Croatia had life expectancy at birth over 80 years. Two inhabited islands, Ilovik (Kvarner islands) and Lopud (South Dalmatian islands), had one of the highest life expectancy at birth recorded in the literature, with 95.0 and 90.6 years respectively. Mortality rates on islands were significantly lower for age groups 50-64 and 65-79 years, and this difference persisted for all island groups compared with general Croatian population. CONCLUSION: Residents of Croatian islands had a higher life expectancy than general or mainland Croatian population. Life expectancy at birth on Croatian islands was lower than in other European Mediterranean countries, but it resembles that in the neighboring Slovenia, and it is considerably higher than in central and eastern Europe and Balkan countries.

[Information system in primary health care]. / Informacijski sustav u primarnoj zdravstvenoj zastiti.

The Croatian Ministry of Health started a health care system computerization project aimed at strengthening the collaboration among health care institutions, expert groups and individual health care providers. A tender for informatic system for Primary Health Care (PHC) general practice, pediatrics and gynecology, a vital prerequisite for project realization, has now been closed. Some important reasons for undertaking the project include rationalization of drug utilization, savings through a reduced use of specialists, consultants and hospitalization, then achievement of better cooperation, work distribution, result linking, data quality improvement (by standardization), and ensuring proper information-based decision making. Keeping non-standardized and thus difficult to process data takes too much time of the PHC team time. Since, however, a vast amount of data are collected on only a few indicators, some important information may remain uncovered. Although decisions made by health authorities should rely on evidence and processed information, the authorities spend most of the time working with raw data from which their decisions ultimately derive. The Informatic Technology (IT) in PHC is expected to enable a different approach. PHC teams should be relieved from the tedious task of data gathering and the authorities enabled to work with the information rather than data. The Informatics Communication Technology (ICT) system consists of three parts: hardware (5000 personal computers for work over the Internet), operative system with basic software (editor, etc.), and PHC software for PHC teams. At the national level (National Public Health Informatics System), a software platform will be built for data collection, analysis and distribution. This data collection will be based on the International Classification of Primary Care (ICPC-2) standard to ensure the utilization of medical records and quality assessment. The system permits bi-directional data exchange between a central database and sources at different levels, across the spectrum from basic PHC teams to local authorities. This will enable data collection control, comparisons with national averages and prompt distribution of information over the Internet. The investment into IT is a strategic imperative having no alternative. A cost/benefit analysis has shown its operation in the PHC system to return the investment in two years. As defined according to the Project priorities (with measurable objectives), the use of new technologies will be introduced by stages.

[ICPC-2--international classification of primary health care and its application in Croatian health care]. / ICPC-2--medunarodna klasifikacija primarne zdravstvene zastite i njena primjena u zdravstvu Hrvatske.

A consensus reached by the medical profession, Croatian Institute of Health Insurance, Croatian Institute of Public Health, and Ministry of Health constitutes a solution to the problem of a data standard required in building an information system for primary health care. This consists of accepting ICPC-2 as a data standard for our Family Medicine, Pediatrics and Women's Health. The classification structure of the International Classification of Primary Care allows, recommends and urges that special codes be established by individual states or local authorities when registering patients' reasons for seeking medical aid or medical procedures. Namely, it urges the authorities to set the codes for such reasons about which a state or local agreement or determination has been made. This is the first public presentation of the proposal Croatia's Additions to the International Classification of Primary Care. They are essential to its implementation in our health insurance, health statistics and medical informatics.

Development and deployment of a health information system in transitional countries (croatian experience).

Croatian Primary Health Care Information System pilot project, conducted between 2001 and 2003, aimed to develop and deploy a health information system based on the latest technologies which would improve the quality of primary health care and rationalise the consumption. 60 primary health care teams (physician and nurse) were equipped with PCs and connected via central server to the main national health insurer, state treasury and public health institute. Developed information system enabled rapid retrieval of documents, replacement of manual data input and a real-time insight into needed information as well as prompt interventions within the system. The project also introduced electronic smart cards for physicians and nurses, so that at each medical check-up the information system verified both the ensuree's and the physician's or nurse's status and rights.Based on the experiences from the pilot project, plan has been made for comprehensive health information system at national level which would connect primary health care teams, hospitals, laboratories, dentistries, health insurance companies, state treasury, public health institutes and electronic health records database. Its major goals are more rapid diagnostics, accuracy in prescribing therapy, standardisation of the good practice as well as better utilisation of capacities, shorter waiting times and shorter stays in hospitals, which would lead to improvement in overall health care quality and better control over the health care consumption. Estimated 5-year investment for installing such system would be 125 million EUR. However, information system could save substantially more and yield a return of investment in only two years.As information system for primary health care should be a strategic component of every health care reform and development plan, we can recommend our model, based on the results of the pilot project, to other transitional countries.

Lost in transition--the Island of Susak (1951-2001).

The isolated population of the Island of Susak was thoroughly studied by a multidisciplinary team of the Croatian Academy of Sciences and Arts in early 1950's. Recently, a team of scientists revisited the island. This paper describes the main characteristics of the transition process during which a massive exodus occurred with 90% of the island's population migrating to New Jersey, USA. We summarise the differences in lifestyle, economy, social structure and sense of identity between the historic (1950's) and contemporary (2001) Susak population. We applied contemporary methods (analysis of microsatellite DNA polymorphisms) to investigate local myths about extreme levels of inbreeding and genetic homogeneity among the Susak islanders. Analysis of short-tandem-repeat (STR) loci showed that Susak displayed characteristics of a small homogeneous breeding isolate. The average heterozygosity was found to be low compared to outbred populations. The signature of a recent severe bottleneck could be detected. Analysis of 8 markers located on Xq13-21 in 71 individuals suggested extensive level of linkage disequilibrium (LD). A migrant study was designed to investigate the effects of large environmental changes (Susak vs. USA) and inbreeding (Susak vs. Croatian general population) on some biologically important quantitative traits, such as blood pressure and serum lipids. The results confirmed the positive correlation between inbreeding level and blood pressure that has been reported in the literature on several occasions. The last remnants of this traditional island community will soon be lost forever.
