Abstract

Using a large-scale dataset from WoS, this paper explores the publications on healthcare risk management, through bibliometric analysis. The bibliometric analysis reflects how research in hospital risk management and healthcare management evolved over time, offering insights on the most relevant and influential research. Based on the idea that researchers publish their most important results in articles, conferences, books and reviews, there is diffusion in this research field, with many reference countries.  The bibliometric analysis reflects the growing interest of research for the area of healthcare risk management. The need to provide high quality medical services requires the design and implementation of a set of key performance indicators for each strategic objective set by the hospital management.  

Keywords: hospital risk management, bibliometric indicators, citation analysis, healthcare.

Introduction

Pritchard Alan (1969), invented the term of bibliometrics, by using it to denote the utilization of mathematical and statistical methods for analysis of written publications. Bibliometrics are used in quantitative research assessment, using key performance indicators for the quality of the research activity. Bibliometrics, or Scientometrics, represents a quantitative analysis method, a statistical technique for journal articles, proceedings papers, reviews, books and their citation counts. The quantitative analysis consists in measuring, recording, computing and analyzing the research results worldwide (Merigo et al., 2015).

The knowledge accumulated over time in the hospital risk management and healthcare fields became more and more complex, requiring new methods and analysis techniques for the decision making process (Tsay M., 2015). Quality and performance assessment in universities, government and researchers is realised with the help of bibliometrics. According to Fetscherin M., Heinrich D. (2015), the citation counts illustrate the relevance, utility and impact of certain papers, the citation analysis pointing if a paper is in top in a specific area of interest. Bibliometrics are used in different areas of studies, from science and humanities to social sciences.

The data source used is Web of science (WoS) of Thomson&Reuters. This database includes more than 160.000 papers, from 250 disciplines and visualizes, analyzes and integrates research papers and citation metrics from 1900. It is a reliable database of reference for the university community, including innovative research with a high degree of originality (Delcea, 2014; Cotfas, 2013).

Hospital risk management is a major concern for risk managers to provide better quality in healthcare. Risks that may occur in a hospital are often interconnected, of utmost importance is determining how these risks affect the appearance of other risks. If the hospital is facing more risks, the risk exposure is increasing, causing vulnerability. (Delcea et al., 2014) According to Bradea et al., (2014), the risks that affect a hospital can be classified into seven categories, namely: mismanagement risk, inability to engage patients risk, technological risk, hospital conditions risk, human resource risk, clinical risk, cyber security and confidentiality of information risk, inadequate funding risk and regulatory issues risk.

Hospital Risk Management: A Bibliometric Overview

The WoS database consists in Science Citation Index Expanded (SCI-EXPANDED), Social Sciences Citation Index (SSCI), Arts & Humanities Citation Index (A&HCI), Conference Proceedings Citation Index- Science (CPCI-S) and Conference Proceedings Citation Index- Social Science & Humanities (CPCI-SSH), that register papers originated from 1900.

To develop the search process we have used the keywords: hospital, healthcare and risk and have been provided with the papers related to this field of interest. The search for these three keywords generated 17044 results. After that, there were obtained 65,049 results for hospital risk management and 1192 results for healthcare risk management.

Most articles in this field were written after 2005, before this year only 14% from total being registered. It can be noticed that the publication number starting from 2005 to 2014 has an increasing trend, with a peak in 2014.

These results classify the information into 85 subject categories and research areas. From these areas of interest were selected the relevant areas for our research that targets the risks that may manifest in a hospital. Thus, after sorting from 1192 results were obtained 550 relevant papers, this bibliometric analysis being focused on the following areas:

Graphically, the articles are distributed on the research areas as in figure no. 3. Depending on the language in which they were published, the largest share is obtained by articles published in English (95.55 %), then were the French articles (1.09 %), Portuguese articles (1.09), German articles (0.73%), Italian articles (0,36%) and Spanish articles (0.18%).

The year 2013 represents the apogee in terms of interest for this domain, with 78 published papers, representing 13,46 % from the total. For the other years the percents were: 2005 (3,82%), 2006 (3.82%), 2007 (6,18%), 2008 (7,64%), 2009(8,36%), 2010 (9,64%), 2011 (10,73%), 2012 (10,55%), 2013 (13,46%), 2014 (10,18%).

Figure no. 7 presents the classification of recorded papers on healthcare risk management. Over 83% of these  articles are published in ISI journals, followed by articles published in conferences proceedings (11.46%). The reviews represent around 10% of the total papers and the editorial materials account less than 1%.

Citation Analysis

One of the most known and used method of bibliometrics, citation analysis identifies the frequency, patterns and diagrams in scientific papers. The results obtained through citation analysis are statistically notable due to the quantity of data collection. The following table illustrates the different types of citations found in WoS.

The h-index is a measure of the citation impact, illustrates the importance of a set of papers. The H-index is a measure for the distribution of citations received by a paper. The value of 35 indicates that 35 papers from a sample have 35 citations.

Analyzing the number of citations for healthcare risk management papers, for the period 1995-20143 it can be easily seen an upward trend, supported by the increased interest in healthcare and risk management. Because for 2015 are recorded papers until February; there is a decrease in the number of citations.

There were recorded 5473 citations and an average of 9,95 citation per paper. The most relevant article on this research area has 184 citations and 15,33 citations per year. There are 30 articles that have the value of the citation per year above 5. The most relevant papers are presented in the following table.
