Spontaneous Reporting
Spontaneous reports are termed spontaneous as they take place during the clinician’s normal diagnostic appraisal of a patient, when the clinician is drawing the conclusion that the drug may be implicated in the causality of the event.
Spontaneous reporting system relies on vigilant physicians, other healthcare professionals, and patients who not only generate a suspicion of an ADR, but also report it.
It is an important source of regulatory actions such as taking a drug off the market or a label change due to safety problems. Spontaneous reporting is the core data-generating system of international pharmacovigilance, relying on healthcare professionals (and, in some countries, consumers) to identify and report any adverse events to their national pharmacovigilance center.
Spontaneous reports are, by definition, submitted voluntarily.
PViMS facilitates a public facing interface that allows clinicians or the public itself to spontaneously report on adverse event related data. See chapter 8 for more information.
Active Reporting
Active surveillance for monitoring the safety and effectiveness of medical products is increasingly recognized as a complement to spontaneous reporting commonly used by pharmacovigilance systems. Integrated mechanisms and processes for monitoring the safety of medicines are essential to a well-functioning pharmaceutical sector. A positive benefit-to-risk balance should precede access to market; however, most regulatory decisions take place early in the product lifecycle and are based on limited data from clinical trials that may be of relatively short duration with limited numbers and types of subjects.
It is critical, therefore, that medicines continue to be monitored for safety and effectiveness once they enter the market under real-life conditions. For some medicines, issues will only emerge under real-world conditions as a result of prolonged use, use in specific subpopulations or in patients with multiple comorbidities, or use in combination with other medicines. In some cases, rare adverse effects only emerge after a product is used for many years, by large numbers of patients, or both.
Active surveillance is particularly important to support the introduction of new essential medicines in LMICs whose regulatory systems are being developed and are in need of support. In resource-limited settings, active surveillance can help determine the real-life frequency, risk factors, and impact of clinically significant adverse medicine events on treatment outcomes.
Pharmacovigilance Activities
| This section describes the common processes adopted by the pharmacovigilance unit in responding to both spontaneous and active reports submitted through PViMS.
· Set terminology for adverse drug reaction (MedDRA) · Set causality per drug (Naranjo or WHO) · Create and update E2B files (Export to XML) · Generate a patient summary |
Terminology
Causality Assessment Scale or Terms. The assessment scales or terms were developed to help standardize assessment of causality for all adverse drug reactions. The result is determined by an algorithm designed by Naranjo or WHO for determining the likelihood of whether an adverse drug event is actually due to the drug rather than the result of other factors. Probability is assigned via a score termed definite, probable, possible or doubtful (Naranjo) or certain, probable/likely, possible, unlikely, conditional, unassessable or unclassified (WHO). Values obtained from this algorithm are sometimes used in peer reviews to verify the validity of author's conclusions regarding adverse drug reactions.
MedDRA Terminology. MedDRA or Medical Dictionary for Regulatory Activities is a clinically validated international medical terminology dictionary by regulatory authorities in the pharmaceutical industry during the regulatory process, from pre-marketing to post-marketing activities, and for data entry, retrieval, evaluation, and presentation. In addition, it is the adverse event classification dictionary endorsed by the International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH).
E2B. The international standard for transmitting medicine adverse event reports specified by the ICH.
1.3.2 Process Flow
| Activity: Start of Process
Clinician adds a new adverse event to the patient record. Reporter adds a new spontaneous report. System generates a new report for the PV unit to action:
|
Confirm Report Data
The purpose of this activity is to facilitate the checking, vetting, and updating of the clinical data collected for the adverse event logged. The PV unit will be unable to perform any causality or terminology configurations until the data is confirmed as accurate and comprehensive. The PV specialist has the following options:
|
| Activity: Confirm Report Data
Step 1: PV specialist and clinician/reporter update clinical data until there is sufficient information to perform causality and terminology configurations. For active reporting the patient record is modified through the clinical portal. For spontaneous reporting the report is modified directly in the analytical portal. Step 2: Once data has been confirmed, the PV specialist will confirm the report is ready for assessment by selecting the Confirm report option. Step 3: The report is moved into a new activity: Set MedDRA and Causality. | |
| Activity: Set MedDRA and Causality
Step 1: PV specialist sets the terminology for the adverse event. This will be the terminology used for analysis purposes. Step 2: PV specialist then sets the causality per medication that was in use at the onset date of the adverse event. Please note: the specialist is unable to set causality until the MedDRA term has been selected. Step 3: On completion, the PV specialist confirms causality has been set. Step 4: The report is moved into a new activity: Extract E2B. |
Set MedDRA and Causality
The purpose of this activity is to facilitate the setting of the MedDRA terminology for the event and to set causality per medication using either the Naranjo or WHO causality scales. The PV specialist has the following options:

2.8.1 Methodology
The following formulas, calculations and definitions are used in the calculation of the relative risk for a specific medication and adverse reaction.
1.8.1.1 Incidence Rate
The incidence rate is the number of new cases per population in a given time period
| IR = (ADR / Population) * 1000
IR = Incidence Rate ADR = Number of adverse drug reactions * Population = Total patient years in reporting period **
* Where causality is set to possible, probably/likely or Certain for WHO assessments and where causality is set to possible, probable or definite for Naranjo assessments
Cases = 11 Non-Cases = 170 Population = 181 (11 + 170) Incidence Rate = 11/181 * 1000 = 60.77 |
1.8.1.2 Relative Risk
Relative risk is defined as the incidence in the exposed over incidence in the non-exposed.
| RR= IR1 / IR2
RR = Relative Risk IR1 = Incidence Rate for exposed population. The exposed population is defined as the patient population that have been exposed to a medication in the reporting period. IR2 = Incidence Rate for non-exposed population. The exposed population is defined as the patient population that have NOT been exposed to a medication in the reporting period.
Incidence Rate Exposed = 60.77 Incidence Rate Non-Exposed = 45.12 RR = 1.35 |
1.8.1.3 Confidence Interval
A confidence interval is a range of values so defined that there is a specified probability that the value of a parameter lies within it. Most commonly, the 95% confidence interval is used.

1.8.3.3 Specifying Risk Factors for the Analysis
To specify a Risk Factor, click the Risk factor field and select the risk factor you would like to include into the analysis. Once you have selected the risk factor, select the appropriate option associated to that risk factor and click the add icon to add the risk factor to the selected list.
You are able to add as many risk factors as you would like to include into the analysis by repeating the above process.
By including Risk Factors into the analysis, the system will determine which patients match the criteria stipulated by the set of risk factors and the corresponding Relative Risk Ratio will be adjusted based on the new population set.
1.8.3.4 Running the Analysis
Once the Patient Population, Date Range, and Risk Factor parameters have been selected, click on the Analyse button to execute the analysis.
The system will conduct an initial analysis that will identify what Adverse Drug Reactions have been identified over the reporting period. All results are included in the Analysis Results tab. Please note that only adverse drug reactions where a MedDRA term has been selected by the PV technician will be selected.
Select the Adverse Drug Reaction that you would like to detect signals for by clicking on the tab for that reaction. The selected tab will turn a dark blue to signify that it has been selected.
Please note that selecting the Adverse Drug Reaction will enable the Dashboard and Patients tab.
You are able to now view a 2 by 2 table illustrating relative risk and 95% Confidence Interval for the selected reaction.
· Incidence Rate for exposed group
· Incidence Rate for non-exposed group
· Relative Risk for the associated medication
· 95% Confidence Interval for the associated medication
