Figure 11 reports the respondents’ perception of commitment for knowledge transfer and integration. 2000;46:186–204. However, the main criticism is that additional variables are not able to go much beyond the original dimensions [64]. These starting assumptions were reached using domain expertise of typical home healthcare costs and the estimated readmission rates from two hospitals with differing patient demographics. They facilitate the analysis of the entire data in real time by developing and using machine-to-machine algorithms for predictive modelling and to arrive at decisions based on such models [1]. Work Pap Inf Syst. An automated model to identify heart failure patients at risk for 30-day readmission or death using electronic medical record data.

For example, according to Cukier [56], Wal-Mart generates about 2.5 petabytes per hour (or 5825.42 gigabits per second). Topaz M, Radhakrishnan K, Blackley S, Lei V, Lai K, Zhou L. Studying associations between heart failure self-management and rehospitalizations using natural language processing. Even when there is no significant mismatch in the data type, the static nature of relational database schemas is not suitable for a dynamic and exploratory environment ([51], p. 13). A popular system by researchers at Yale University is freely available online at readmissionscore.org. As new patients enter the hospital, the ground truth readmission label will not be known for up to 30 days. Even though the four dimensions identify different aspects of OLC, they are closely related to each other. Accessed 15 Jun 2015. 2 > 0.50) and low standard error (SE < 0.08), This study uses SEM and OLS to test the hypotheses. 2016;6(4):256–61. The omission of a term in unstructured text is assumed to be purposeful and missing values, whether intentional or unintentional, are represented by the number zero. The concept of organisational learning has emerged in the field of organisational studies and received increasing attention in the field of information systems and technology management [30, 31]. 3 lists the V’s mentioned by various authors. Hassan IM, Khan HU, Lalitha M. Pedagogical potentials of IEEE 802.11 WLAN to Nigerian Universities: a case study of the University of Uyo.

According to a study conducted by Philip Chen and Zhang [42] it is revealed that high-tech data storage, management, analysis capability and visual technologies are all part of big data analytics [43]. The last regression aims to test the moderation Hypotheses 3a, 4a, 5a, 6a, 3c, 4c, 5c, and 6c. C-statistic serves as a poor proxy for cost, yet few researchers have incorporated cost into readmission models [9, 10]. 10 For Model 3, β The sample size is the last column. Challenges of E-commerce in developing countries: Nigeria as case study, Northeast Decision Sciences Institute Conference, Alexandria, Virginia, USA, March 31–April 2 2016; 2016. Beyond any doubt data analytics has become an integral part of and is integrating information and management sciences. Both theories are from the field of psychology and suggest that behaviour is determined by beliefs and evaluations (attitude towards behaviours) and also normative belief to comply (subjective norms). The authors declare that they have no competing interests. This problem could be a result of model misspecification, excessive residuals or multicollinearity. 2015;13(1):30–41. Though readmission classification systems may provide some insight to medical facilities with no statistical readmission reduction strategy in place, integrating cost into machine learning models has shown to significantly reduce cost by optimally selecting only those patients in greatest need of intervention.

Berlin: Springer; 1985. One potential strategy is to provide patient education and follow-up. For the next dimension, openness and experimentation the hypotheses are. 2009;77(1):103–23. Big data technologies have to process information in real-time (streaming processing). The next set of hypotheses refers to the interaction between system perspective of OLC and TAM model. In fact, the proposed model is able to explain more variation of the technology acceptance of big data analytics than the TAM alone. Rumshisky A, Ghassemi M, Naumann T, Szolovits P, Castro VM, McCoy TH, Perlis RH. J Manag Inf Syst. Age Ageing. [8] found the correlation between c-statistic and hospital readmission cost to be low (cor = − 0.21). MIS Q. volume 4, Article number: 37 (2017) Most of the respondents are between 31 and 40 years old; which is expected for experienced professionals undertaking a Master’s degree. As shown in Fig. Structural equation modelling represents a contemporary statistical technique for testing and estimating the relation between the factors and variables [91]. The definition of journal acceptance rate is the percentage of all articles submitted to Journal of Big Data that was accepted for publication. This validation of measurement scales and statistical analysis program allows future researchers to replicate and expand this study. Moreover, business professionals can create a pre-implementation assessment instrument to evaluate the technology acceptance. These penalties often exceed potential reimbursement and have motivated hospitals to work towards readmission reduction [3]. These theories combined with the studies of Swanson [29] provided ground to determine the beliefs that are sufficient pre-empt the attitude of the end-user towards the adoption of a system. N Hospitals attempting to reduce HRRP penalties may use target readmission rates set by CMS to decide how to allocate resources. A survey based approach. Few of these variables can be affected administratively and for modeling purposes considered unchangeable. The statistical analyses have shown unexpected results, i.e., significant strong negative correlation in the OLS regressions. The Journal of Finance publishes leading research across all the major fields of financial research. Recent US legislation imposes financial penalties on hospitals with excessive patient readmissions. This analysis can often be done as a nightly batch process to gather a sufficiently large number of patients for calculation. The final model fit for the multi-item scales [χ2 (93.3, N = 359) p > 0.001; GFI > 0.95; NFI > 0.97; CFI > 0.98; RMSEA = 0.048], which are in the expected range [93]. Philip Chen CL, Zhang CY. Predicting 30-day risk and cost of ‘all-cause’ hospital readmissions. The most efficient media for data transfer, i.e., fibre optic cable, can transfer up to 100 gigabits per second (0.043 petabytes per hour) [57, 58]. 32, No. Transl Psychiatry. Assuming N It is worth mentioning that a general purpose computer needs more than three instructions to process a byte [52–54]. Shuvra S. Bhattacharyya, Jarmo Takala; Publishing model Hybrid. A critical review of the technology acceptance model. This mandatory use is particularly relevant to well-established technologies, like enterprise resource planning or collaboration suites, which cannot be overlooked. Das A, Khan HU. Other researchers claim that the accumulation of knowledge can create competency traps that diminish organisational efficiency [79]. Big Data Analytics is a multi-disciplinary open access, peer-reviewed journal, which welcomes cutting-edge articles describing original basic and applied work involving biologically-inspired computational accounts of all aspects of big data science analytics. Senge PM, Suzuki J. OLC variables are also converted to dichotomous variables for better reliability in the moderation tests (Ping Jr [96–98]. Systems trained using localized hospital data often fare better, but rarely produce c-statistic scores greater than 0.7 [6]. From intentions to actions: a theory of planned behavior. In some contexts, such as online banking, the model explains even less extent of technology usage [71]. AA critically reviewed the manuscript. A research by Fairchild and Mackinnon [6] revealed that organizational learning capability (OLC) is pivotal factor for adoption of system and technological solutions. This research was supported in part by NSF Grants IIP-1444949 and IIP-1624497. In some cases, reaching a zero ERR may not be possible due to a high initial ERR or small number of new patients under analysis. Accessed 10 June 2015. Exceeding CMS target rates does not result in a refund or negative penalty [2]. Focusing resources toward the potentially most expensive patients offers considerably better results than unfocused efforts. Organ Sci. The definition of journal acceptance rate is the percentage of all articles submitted to IEEE Transactions on Big Data that was accepted for publication. 2006;27:235–63. Frequently occurring terms in discharge summaries. Since the patients have been sorted by decreasing order of readmission probability and number of patients in analysis is constant, it is possible to iteratively increase the number of patients to intervene until a minimum cost is achieved. Futoma J, Morris J, Lucas J. These are not to be taken as absolute costs of a typical hospital. Batra S. Big data analytics and its reflections on DIKW hierarchy. According to Kenny [99], a mediation effect is worth considering when ACME > 0.30.

A comparison of models for predicting early hospital readmissions. The limitations discussed in both the fields, academic and business, highlight significant prospects for future study. It is the most widely cited academic journal on finance. 23 However, these TAM dimensions do not take the organisational environment that certainly influence system usage into account [22]. Manage Sci. The Hospital Readmission Reduction Program (HRRP) aims to reduce payments to hospitals which have an excess of avoidable readmissions [2]. Hypothesis 5b: Openness and experimentation positively relates to the intended usage of big data analytics. Figure 4 shows the relationship between the elements of TAM [9]. Therefore, finding factors that increase customer churn is important to take necessary actions to reduce this churn. are constrained to zero to test Hypothesis 1 and 2. Dillman DA.

Hospital Readmission Reductions Program formulas and probability of readmission are applied using four readmission scenarios to estimate the cost of readmission. Reardon S. Preventable readmissions cost CMS $17 Billion. C-statistic is defined as the area under a receiver operating characteristic (ROC) curve. IEEE Data Eng Bull. Though many supervised machine learning algorithms have the ability to coerce classification distribution, the NB machine learning algorithm naturally produces posterior probabilities without coercion [19]. Estimating the nonlinear and interactive effects of latent variables. According to Kim [83], organizational learning affects individual learning that then results in the adoption of new technologies. Big data challenges. Boston: Addison Wesley; 2009. 2002;19:175–218. More importantly, editors of journals reject papers for a variety of reasons and often provide helpful comments to authors as feedback. Account Manag Inf Technol. This representation allows discharge summaries to be used with the NB machine learning algorithm, which predicts the probability of readmission. Boccuti C, Casillas G.
