ABSTRACT
Aim: To survey person centered survival rate in population based screening program by an intelligent clinical decision support system
Background: Colorectal cancer is the most common malignancy and major cause of morbidity and mortality throughout the world. Colorectal cancer is the sixth leading cause of cancer death in Iran. In this survey, we used cosine similarity as data mining technique and intelligent system for estimating survival of at risk groups in the screening plan
Methods: In the first step, we determined minimum data set [MDS]. MDS was approved by experts and reviewing literatures. In the second step, MDS were coded by python language and matched with cosine similarity formula. Finally, survival rate by percent was illustrated in the user interface of national intelligent system. The national intelligent system was designed in PyCharm environment
Results: Main data elements of intelligent system consist demographic information, age, referral type, risk group, recommendation and survival rate. Minimum data set related to survival comprise of clinical status, past medical history and socio-demographic information. Information of the covered population as a comprehensive database was connected to intelligent system and survival rate estimated for each patient. Mean range of survival of HNPCC patients and FAP patients were respectively 77.7% and 75.1%. Also, the mean range of the survival rate and other calculations have changed with the entry of new patients in the CRC registry by real-time
Conclusion: National intelligent system monitors the entire of risk group and reports survival rates by electronic guidelines and data mining technique and also operates according to the clinical process. This web base software has a critical role in the estimation survival rate in order to health care planning
ABSTRACT
Though increased risk of gastric cancer in individuals with family history of the disease has been observed consistently in previous studies, data on the association between gastric cancer and family history of cancer from Iran is scanty. The purpose of this study is to evaluation of gastric cancer risk associated with family history cancer. The present study was designed as unmatched case-control study. Cases were 746 histopathologically confirmed gastric cancer and 746 controls were randomly selected among the healthy participants in a health survey. The family history of cancer was extracted from a standard history form completed by the patients or health care providers. Mantel-Heanszel Odds Ratio was computed for removing the confounding effect of age and sex. A positive family history of cancer was reported by 9.7% and 5.6% of cases and controls, respectively. Gastric cancer risk increased two-fold for subjects reporting any first degree relative with gastric cancer. There is no statistical association among family history of other cancers and gastric cancer [P>0.05]. In conclusion, this study showed that family history of gastric cancer, especially in firstdegree relatives, increases the risk of gastric cancer. Further studies are needed to better understand the role of genetic factors and environmental factors and their interaction in gastric cancer development in Iranian community
ABSTRACT
Background: A pharmacy information system must retrieve process and update the information it obtains for safe and effective use of drugs. It is used to manage drug usage in the patient health care process and to communicate a large volume of information to pharmacy and pharmaceutical firms. Bearing in mind such issues, the current study adopted a descriptive method of research to investigate the pharmacy information systems in university hospitals and their relationship with pharmaceutical firms. The research data were collected through observation and interview based on a checklist and a questionnaire. Validity and reliability of the data gathering tools were specified through content validity and test re-test methods. The collected data were then analyzed, using a set of descriptive statistics. According to the results, pharmacy information systems in the hospitals under study were partially computerized. Databases for drugs, patients and prescriber databases, with different values of 50.1%, 21.9%, and 33.3% respectively, were not complete, as had been recorded in the pharmacy information system of the hospitals. The pharmacy information system is normally used to support therapeutic activities and the inventory, but such support had not been provided for 43.9 % of the hospitals. 32.2 % of the hospitals under study had not reported pharmaceutical information such as statistical data and drugs' prices. Also, 27.3% of the pharmaceutical firms did not have any relationship with pharmacy information systems. Pharmaceutical companies had developed some relationship, on marketing issues, with hospital pharmacies. The findings were in favor of further therapeutic activities by pharmacy information systems, which could be achieved by improving relationship between hospitals and pharmaceutical firms, particularly in Tehran. This could help to manage drug consumption and supervision, after marketing, in order to eliminate adverse drug reactions and develop high quality pharmaceutical services
ABSTRACT
Application of health informatics, especially for screening process of colorectal cancer, is a most effective and cost efficient method for monitoring, management and prevention of disease. Information systems have capability for sharing and integration of information among the many stakeholders involved in colorectal cancer control (participant, family physician, specialist, hospitals, laboratories, and pharmacist). In this paper, we provide comprehensive survey applications and functions of health informatics and information systems in preventing colorectal cancer and management of screening process. Furthermore, we cover different models, infrastructures and standards for reporting and distribution of information at the international level, with due attention to security and privacy issues. The information furnished in this article was collected from valid medical databases by medical librarians.
