What is OpenVigil?

OpenVigil 1 and 2 are software packages to analyse pharmacovigilance (adverse drug event) data. There are several national and international databases of so called spontaneous adverse event reports, e.g., the U.S. american FDA Adverse Event Reporting System (AERS, mostly domestic data) or the WHO Uppsala Monitoring Centre (international). Currently, analyses of FDA AERS (LAERS & FAERS) pharmacovigilance data are available. In addition to U.S. american data, we have also imported German pharmcovigilance data. Data mining features include highly configurable search criteria filters and output filters. Analyses include disproportionality analyses for signal detection like Proportional Reporting Ratio (PRR) calculations. Results can be viewed, sorted and filtered in the webbrowser or saved for further analyses in statistical software packages. Both projects aim at integrating these and other pharmacolovigilance sources to pharmacoepidemiological data like prescription data. OpenVigil 2 is designed for complete case analyses.
OpenVigilFDA is a front-end to the openFDA-interface which is being developed by the FDA since 2014. It allows extraction of the latest reports. Due to technical limitations, the beta-version status and the ongoing changes to the API of openFDA, OpenVigil 2 is more stable and superior for analyses of disproportionality. OpenVigilFDA provides available case analysis, e.g., some records are not complete but still considered.

The OpenVigil project does not produce or gather any of the pharmacovigilance data itself but is dependent on external data sources.
Our software is being developed for physicians, pharmacists and scientists. Due to the origin and nature of the data and the ongoing work on our programs, all results should be considered unvalidated. Especially, any findings must not be used uncritically for therapy changes or legal proceedings. However, these data are well usable for hypothesis generation.

Pharmacovigilance reporting flow What is pharmacovigilance?

Pharmacovigilance is defined as the science and activities relating to the detection, assessment, understanding and prevention of adverse effects or any other drug-related problem.

Why do we have pharmacovigilance?

Triggered by the thalidomide (Contergan®) tragedy 1957-1961, various countries have introduced the systematic collection of spontaneous filed reports of adverse events occuring during or after pharmacotherapy. This ongoing monitoring of (newly approved) drugs ensures detection of rarely occuring adverse event and other types of issues with the pharmaceutical product or the patient adhearance to it. So, while clinical trials can contribute to drug safety, pharmacovigilance can improve drug therapy safety!

What type of data is gathered?

Reports can be filed by physicians, pharmacists, pharmaceutical companies and patients. Depending on the domestic laws, it is mandatory for most of these parties to report any observed adverse event. Recent EU directives recommend to gather reports from patients. The quality of the data is thus diverse: Some are unusable due to missing data. One the other hand, reports made by pharmaceutical contain a lot of information due to enforced laws concerning patient security. Most pharmacovigilance databases traditionally contain some basic data on the patient (e.g., gender and age), the adverse event(s) and a list of drugs. Depending on primary data sources (e.g., outpatient or hospital patient) and policy of the agency that is taking care of the database, other data, e.g., indications or laboratory values, can be added.
By the nature of this 'spontaneous collection' these data have to be treated with caution and are generally not suited for hypothesis confirmation but only for hypothesis generation.

How does analysis of pharmacovigilance data contribute to healt care?

Pharmacovigilance data-mining for signals of disproportionate reporting (SDR), i.e., disproportionally stronger associations between drugs and adverse events, is routinely done by the regulatory authorities. However, pharmacovigilance data is not only useful for monitoring new drugs but also for detecting more complex signals, e.g., drug-drug interactions or syndromes or to further analyse known signals and find a especially vulnerable population or mode of application (so called multi-item data mining). Data should be enriched with ontologies for these analyses (e.g., MedDRA, RxNorm, SNOMED, ATC, ICD-10/11).

Where can I extract or analyse pharmacovigilance data?

Open access to pharmacovigilance data is limited. The freedom of information act (US) and similar laws in other jurisdictions have led to the availability of raw data (e.g., FDA AERS datafiles) and new portals to access data (e.g., EMA http://www.adrreports.eu/). A list of possible access and analysis options is provied in our resource library page.
However, the open availability combined with the advanced and cleaning, filtering, extraction and analysis capabilities of OpenVigil 2 are unique: All pharmacovigilance research using OpenVigil software is completely transparent and reproducible, thus allowing other scientists to confirm any findings and expand the analyses.

How are statistical signals in pharmacovigilance data detected?

Statistical detection of signals whether a drug-event combination is a putative dverse drug reactions or just a random association can be done using either (i) frequency based methods comparing estimated counts to observed counts for a drug-event-combination like Relative Reporting Ratio (RRR), Proportional Reporting Ratio (PRR) or Reporting Odds Ratio (ROR) or Likelihood Ratio Test (LRT), (ii) Bayesian probabilities like Bayesian conidence propagation neural network (BCPNN) or Poisson-Dirichlet process (DP) or (iii) the (Multi-item) Gamma Poisson Shrinker (GPS/MGPS).
All OpenVigil software provides RRR, PRR and ROR which are similar in magnitude and explanatory power. These measurements of disproportionality are calculated as RRR=DE*N/(D*E), PRR=(DE/D)/(dE/d) and ROR=DE*de/(De*dE). A value of 1 is considered normal background noise. The confidence interval can be estimated using Chi-squared with Yates' correction chisq > 4 or lower bound of the 95% confidence interval (CI) of RRR, PRR or ROR, e.g. for s = sqr( 1/DE + 1/De + 1/dE + 1/de ) for ROR with CI = e ^ ( ln ROR ± 1,96s ) OpenVigil 2.2 will offer MGPS calculations. This signal detection algorithm is especially suited for small numbers of drug-event combinations (DE). Signal detection can be used to find a subgroup of vulnerable patients. By stratifying the reports by age, gender, mode of administration, dosage, indication or other categories, it is possible to identify any confounders and/or vulnerable patients.

Pharmacovigilance Open World Problem What are the usual pitfalls when analysing pharmacovigilance data?

By the very nature of this data collection, it represents only a certain part of the general population in health care (the so-called "open world" problem). Issues like under/over-reporting and counting issues due to multiplicates are summarized in the OpenVigil 1 & 2 cave-at document.
The quality of reports and the verbatim text items, e.g., DRUG.DRUGNAME in the FDA AERS data, require preprocessing of the records and a careful validation of any analysis results. OpenVigil 2 provides cleaning of imported data by using external databases like drugbank.ca and user input.
An analysis of pharmacovigilance data can usually not confirm a hypothesis. E.g., you cannot use it proof a certain association. In some situations it might support a hypothesis. Instead, pharmacovigilance data is routinely used to generate a new hypothesis that requires testing in more in silico, preclinical or clinical research, as well as to give therapy guidiance in direct health care.

Which clinical or scientific questions can be addressed by analysing pharmacovigilance data?

Obviously, detecting new adverse drug reactions are the primary reason why pharmacovigilance has been implement and thus they are the most important analysis goal. Other usages include detection of especially vulnerable subpopulations, of harmful excipients/brands, of toxic chemical moieties, of syndromes, of drug-drug-interactions, comparing drugs within drug class and for drug repositioning/repurposing.

How about other usage (e.g., marketing or legal proceedings)?

Because of the limitations of pharmacovigilance data analysis due to the origin and nature of the data, any findings of disproportionality do generally not allow to proof an assumption or to suport a hypothesis. Occassionally, it might be usefull to show that a certain signal was present or not present at a certain date in the past for these purposes. Interpretation of queries requires sound knowledge of statistics, pharmacy, pharmacology and clinical significance of any findings. To fully understand the results, a team combining expertise in these areas is recommended.

Technical documents: Installation, Data cleaning, Caveat, Citing

Due to the nature of the method of collecting pharmacovigilance data and the nature of the data itself, several precautions need to be taken for high-quality analyses of drugs and their putative adverse drug reactions. This is especially important if you chose to install OpenVigil yourself.

(DAPI), http://www.dapi.de), Berlin, and the creators of OpenVigil (Institute of Experimental and Clinical Pharmacology and Department of Computer Science, University of Kiel) have joined their expertise and commenced to assess how pharmacoepidemiologic and pharmacovigilance data can improve signal detection for certain drug/adverse event-combinations. The correlation of data on drug usage and adverse events might also improve estimations of the incidence of a certain drug/adverse event-association.

    • Logo WWKLogo UKSH2015-06-30 (Updated 2015-10-03) The ability of OpenVigil to help with clinical decisions (project title "From the Adverse Event to the most likely Culprit") is now being evaluated at wards at the UKSH Kiel and at the hospital pharmacy at Werner Wicker Klinik, Bad Wildungen. The goal is to find the most likely pharmacological cause of a newly occurring adverse event during pharmacotherapy. Medical doctors and pharmacists are being trained how to systematically estimate the most likely cause of a new adverse event by using both "eminence-based approaches" (i.e., internal SOPs which specialist or guideline to consult) and evidence-based medicine (EBM) like SIDER ( http://sideeffects.embl.de/ ), OpenVigilFDA ("List the most likely drugs in a list of medications causing a specified adverse event and compare likelihoods") and OpenVigil 2 (reverse DPA "Frequentist methods"). During this project, the utility of this analysis method shall be evaluated (e.g., decrease of costs, adverse events or length of stay in hospital) and a new user interface to address this clinical problem and offering easily readable output will be created (in parts done in OpenVigilFDA, pending for OpenVigil 2).
