Abstract
Patient safety is a global problem and one of the key elements of the quality of health care systems. The human factor is a major risk factor leading to medical errors that affect patient safety. To explore the impact of this factor on patient safety in the hospitals located in the Ha'il city in Saudi Arabia; the perceptions of nurses working in governmental hospitals were assessed using a selfstructured questionnaire. Descriptive statistics were presented for the studied variables. Significant differences between the categories of the respondents' characteristics in relation to risk factors were assessed using the Mann-Whitney test; the Kruskal-Wallis and the Spearman rank correlation test. Only 50% of the factors tested were perceived as moderate risk factors that were negatively affecting patient safety in Ha'il hospitals; namely: 'Poor teamwork among medical staff'; 'Unqualified medical staff' and 'Miscommunication among medical staff'. The substantial differences among demographic characteristics of the study sample in relation to the human resources risk factors causing medical errors was identified at P<0.05. Although the human risk factors were ranked as low to moderate; attention to and concern for all risk factors is needed by policymakers and hospital managers in order to improve patient safety in the healthcare settings in the Ha'il city in KSA.
