  Inclusion dependencies form one of the most fundamental classes of integrity constraints. Their importance in classical data management is reinforced by modern applications such as data profiling, data cleaning, entity resolution and schema matching. Their discovery in an unknown dataset is at the core of any data analysis effort. Therefore, several research approaches have focused on their efficient discovery in a given, static dataset. However, none of these approaches are appropriate for applications on dynamic datasets, such as transactional datasets, scientific applications, and social network. In these cases, discovery techniques should be able to efficiently update the inclusion dependencies after an update in the dataset, without reprocessing the entire dataset. We present the first approach for incrementally updating the unary inclusion dependencies. In particular, our approach is based on the concept of attribute clustering from which the unary inclusion dependencies are efficiently derivable. We incrementally update the clusters after each update of the dataset. Updating the clusters does not need to access the dataset because of special data structures designed to efficiently support the updating process. We perform an exhaustive analysis of our approach by applying it to large datasets with several hundred attributes and more than 116,200,000 million tuples. The results show that the incremental discovery significantly reduces the runtime needed by the static discovery. This reduction in the runtime is up to 99.9996 % for both the insert and the delete.

  [ Abstract ] [ BibTeX ] [ Download ] [ Details ]
   
  Providing patients access to mental health records is a controversial topic that gains growing attention in research and practice. While it has great potential in increasing the patient engagement, skepticism is prevailing among therapists who fear detrimental effects and face a lack of feasibility when treatment notes are handwritten. We aim at empowering both therapists to new documentation approaches and patients to higher engagement, and develop the collaborative documentation system Tele-Board MED (TBM) as an adjunct to talk-based mental health interventions. We present an evaluation of TBM by comparing four prototypes and testing scenarios, reaching from early simulations to attempts of real-life implementations in clinical routines. This paper delivers a systematic need comparison of therapists as primary users and patients as secondary users, both during and beyond treatment sessions. While patient feedback is thoroughly positive, the therapist needs are only partially addressed; the benefits remain hidden behind the perceived effort.

  Inclusion dependencies (INDs) within and across databases are an important relationship for many applications in data integration, schema (re-)design, integrity checking, or query optimization. Existing techniques for detecting all INDs need to generate IND candidates and test their validity in the given data instance. However, the major disadvantage of this approach is the exponentially growing number of data accesses in terms of the number of SQL queries as well as I/O operations. We introduce Mind2, a new approach for detecting n-ary INDs (n > 1) without any candidate generation. Mind2 implements a new characterization of the maximum INDs we developed in this paper. This characterization is based on set operations defined on certain metadata that Mind2generates by accessing the database only 2 x the number of valid unary INDs. Thus, Mind2 eliminates the exponential number of data accesses needed by existing approaches. Furthermore, the experiments show that Mind2 is significantly more scalable than hypergraph-based approaches.

  There is significant, unexploited potential to improve the patients’ engagement in psychotherapy treatment through technology use. We develop Tele-Board MED (TBM), a digital tool to support documentation and patient-provider collaboration in medical encounters. Our objective is the evaluation of TBM's practical effects on patient-provider relationships and patient empowerment in the domain of talk-based mental health interventions. We tested TBM in individual therapy sessions at a psychiatric ward using action research methods. The qualitative results in form of therapist observations and patient stories show an increased acceptance of diagnoses and patient-therapist bonding. We compare the observed effects to patient-provider relationship and patient empowerment models. We can conclude that the functions of TBM – namely that notes are shared and cooperatively taken with the patient, that diagnostics and treatment procedures are depicted via visuals and in plain language, and that patients get a copy of their file – lead to increased patient engagement and an improved collaboration, communication and integration in consultations.

  Inclusion dependencies within and across databases are an important relationship for many applications in anomaly detection, schema (re-)design, query optimization or data integration. When such dependencies are not available as explicit metadata, scalable and efficient algorithms have to discover them from a given data instance. We introduce a new idea for clustering the attributes of database relations. Based on this idea we have developed S-indd, an efficient and scalable algorithm for discovering all unary inclusion dependencies in large datasets. S-indd is scalable both in the number of attributes and in the number of rows. We show that previous approaches reveal themselves as special cases of S-indd. We exhaustively evaluate S-indd's scalability using many datasets with several thousands attributes and rows up to one million. The experiments show that S-indd is up to 11x faster than previous approaches.

  [ Abstract ] [ BibTeX ] [ Download ] [ Details ]
   
  Therapeutic documentation is a crucial part in psychotherapy and should first and foremost support the patient’s therapy progress. Yet, the notes taken throughout a therapy, mainly serve the use of therapists. In line with the movement of patient empowerment, the calls for patients’ access to their records are growing louder and were incorporated into the German patients’ rights law. Hence, with Tele-Board MED, an interactive system for joint documentation of therapist and patient was developed. In this paper, we introduce one of its many features: the automatic creation of treatment session summaries. Our contribution also consists of the evaluation of its potential for practical use by psychotherapists. The aim of our work is twofold, namely the involvement of patients in the documentation, and the support of therapists with their documentation duties. The aspects of investigation include the therapists’ documentation habits (regarding time, amount, and method), their purposes to manually create session summaries and opinion about the automatically created summaries. It was discovered that the bigger part of the motivation for treatment session documentation lies in the therapists’ personal purposes, such as remembering a case right before the next session. Nevertheless therapists are willing to turn documentation in a cooperative activity if they had effective and efficient tools at hand. With the system presented, they can well imagine summarizing important issues together with the patient at the end of a session and also handing out printed summaries to them.

  [ Abstract ] [ BibTeX ] [ Download ] [ Details ]
   
  Keeping data confidential is a deeply rooted requirement in medical documentation. However, there are increasing calls for patient transparency in medical record documentation. With Tele-Board MED, an interactive system for joint documentation of doctor and patient is developed. This web-based application designed for digital whiteboards will be tested in treatment sessions with psychotherapy patients and therapists. In order to ensure the security of patient data, security measures were implemented and they are illustrated in this paper. We followed the major information security objectives: confidentiality, integrity, availability and accountability. Next to technical aspects, such as data encryption, access restriction through firewall and password, and measures for remote maintenance, we address issues at organizational and infrastructural levels as well (e.g., patients’ access to notes). With this paper we want to increase the awareness of information security, and promote a security conception from the beginning of health software research projects. The measures described in this paper can serve as an example for other health software applications dealing with sensitive patient data, from early user testing phases on.

  The potential of mental health interventions supported by computers has rarely been explored to date, and the use of technology has hence been limited. There is a need for finding new ways of providing engaging psychotherapy services. We introduce the digital whiteboard system Tele-Board MED (TBM) as a new approach of promoting patient-therapist interaction and joint documentation. Based on observations of cognitive behavioral therapy (CBT) sessions and a text material review we identified possibly useful features. We conducted a qualitative and quantitative feedback study with 34 therapists in the form of a questionnaire based on a video showing the system’s fundamental concept and features. This allowed us to evaluate the therapists’ attitudes and the ability of a system like TBM to meet user needs. We encountered willingness to use the system primarily driven by practical interest in fulfilling administrative and legal requirements. Skepticism regarding patient file transparency and technology use was also found. The main insight is that reestablishing the nature of CBT sessions towards higher patient engagement can more successfully be pursued if technology provides incentives for therapists, such as features that speed up administrative tasks.
