ABSTRACT The potential of health information technology (IT) to transform health care delivery has spurred health IT adoption and will likely contribute to increased investments in coming years. Although an extensive literature shows the value of health IT at leading academic institutions, its broader value remains unknown. We sought to estimate IT's effect on key patient safety measures in a national sample. Using four years of Medicare inpatient data, we found that electronic medical records have a small, positive effect on patient safety. Although these results are encouraging, we suggest that investment in health IT should be accompanied by investment in the evidence base needed to evaluate it.

    ABSTRACT: This paper is located within the global debates about integrated Health Information Systems (HIS) in developing countries. From a Namibian experience, this paper examines the major challenges and constrains facing the integration of HIS. The rationale for the examination stems from the notion that the Namibia healthcare is yet to integrate the HIS, despite huge investments and efforts being made on ground. Based on own experience and backed up by a literature review, semi-structured interviews, and participant observation, major challenges and constraint in the integration of HIS and possible solutions are presented and structured. Finally the paper proposes measures within the HIS in the form of annual health provider's workshop that could be implemented in order to share the experiences and lesson learned.

    • "One is to measure IT adoption by whether or not hospitals adopt a specific IT system. Several researchers have used this method to identify adoption of IT systems, such as Computerized Physician Order Entry (CPOE) systems and Electronic Medical Record (EMR) systems [1,4,5,7,9]. However, such studies cannot broadly explain technology acquisition and utilization because they ignore the other clinical IT systems in use. "

    ABSTRACT: The objective of this study was to create a new measure for clinical information technology (IT) adoption as a proxy variable of clinical IT use. Healthcare Information and Management Systems Society (HIMSS) data for 2004 were used. The 18 clinical IT applications were analyzed across 3,637 acute care hospitals in the United States. After factor analysis was conducted, the clinical IT adoption score was created and evaluated. Basic clinical IT systems, such as laboratory, order communication/results, pharmacy, radiology, and surgery information systems had different adoption patterns from advanced IT systems, such as cardiology, radio picture archiving, and communication, as well as computerized practitioner order-entry. This clinical IT score varied across hospital characteristics. Different IT applications have different adoption patterns. In creating a measure of IT use among various IT components in hospitals, the characteristics of each type of system should be reflected. Aggregated IT adoption should be used to explain technology acquisition and utilization in hospitals.

    • "Amarasingham et al. [4] reported a study involving a sample of 41 Texas hospitals that found that the extent of automation of clinical information processes was associated at statistically significant levels with lower inpatient mortality and fewer patient complications. In a study involving 2,707 hospitals, Parente and McCullough [5] investigated the association between three HITs (EMRs, nurse charts, and PACS) and three patient safety indicators (infection due to medical care, postoperative haemorrhage or hematoma, and pulmonary embolism or deep vein thrombosis). The only statistically significant association found was between EMRs and reduced infections due to medical care. "

    ABSTRACT: Background Recently, there has been considerable effort to promote the use of health information technology (HIT) in order to improve health care quality. However, relatively little is known about the extent to which HIT implementation is associated with hospital patient care quality. We undertook this study to determine the association of various HITs with: hospital quality improvement (QI) practices and strategies; adherence to process of care measures; risk-adjusted inpatient mortality; patient satisfaction; and assessment of patient care quality by hospital quality managers and front-line clinicians. Methods We conducted surveys of quality managers and front-line clinicians (physicians and nurses) in 470 short-term, general hospitals to obtain data on hospitals’ extent of HIT implementation, QI practices and strategies, assessments of quality performance, commitment to quality, and sufficiency of resources for QI. Of the 470 hospitals, 401 submitted complete data necessary for analysis. We also developed measures of hospital performance from several publicly data available sources: Hospital Compare adherence to process of care measures; Medicare Provider Analysis and Review (MEDPAR) file; and Hospital Consumer Assessment of Healthcare Providers and Systems HCAHPS® survey. We used Poisson regression analysis to examine the association between HIT implementation and QI practices and strategies, and general linear models to examine the relationship between HIT implementation and hospital performance measures. Results Controlling for potential confounders, we found that hospitals with high levels of HIT implementation engaged in a statistically significant greater number of QI practices and strategies, and had significantly better performance on mortality rates, patient satisfaction measures, and assessments of patient care quality by hospital quality managers; there was weaker evidence of higher assessments of patient care quality by front-line clinicians. Conclusions Hospital implementation of HIT was positively associated with activities intended to improve patient care quality and with higher performance on four of six performance measures.
