Study Details

2. Sample Size and Data Provenance

The document states that a comparison study and clinical repeatability testing were performed on four age groups: 0-12 months, 12 months- <5 years, 5 years- <18 years, and 18 years and older. However, the exact sample size for the test set is not explicitly provided in the furnished text.

The data provenance is implied to be prospective clinical data since it refers to a "clinical comparison study" and "clinical repeatability testing" performed in accordance with ASTM E1112-00(2006) and ASTM E1965. The country of origin of the data is not specified.

3. Number of Experts and Qualifications for Ground Truth

The document does not mention the use of experts to establish ground truth.

4. Adjudication Method for the Test Set

The document does not describe an adjudication method.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

There is no mention of an MRMC comparative effectiveness study in the provided text. The study described is a comparison study between the test device, a predicate device, and a gold standard reference thermometer.

6. Standalone Performance Study

Yes, a standalone performance study was done in the sense that the VDT985US Vicks® SmartTemp™ Thermometer (test thermometer) was compared directly to a "gold standard" device (Welch Allyn SureTemp® Plus in monitoring mode) and a predicate device (Vicks V966 Thermometer) to assess its clinical accuracy and repeatability. The results reported are for the device's performance itself.

7. Type of Ground Truth Used

The ground truth used was established by a reference device: the Welch Allyn SureTemp® Plus in the monitoring mode (K030580), which is referred to as the "gold standard."

8. Sample Size for the Training Set

The document does not provide information about a training set or its sample size. The study described appears to be a validation/testing study rather than a development study involving specific training data.

9. How the Ground Truth for the Training Set Was Established

Since no training set is mentioned, this information is not available in the provided text.

5. Device Description:

Overview: The VDT985US Vicks® SmartTemp™ Thermometer is a general purpose thermometer. The thermometer is intended for oral, axillary temperature measurements of the human body. The main user interface for the thermometer is a smartphone or other Bluetooth smart device on which the Kaz SmartTemp app is installed. The thermometer communicates with the user's device through a Bluetooth smart connection.

Bluetooth Smart Radio and MCU: The Bluetooth Radio is part of a system on chip (SoC) by Texas Instruments. The CC2541 is comprised of a Bluetooth Smart radio and 8051 MCU. The unit defaults to sleep mode, in which the radio is off and the MCU is in time keeping low current mode. The thermometer measures temperature through a thermistor located in the tip of the device, which is measured using a resistor divider sampled by an onboard Analog to Digital Converter (ADC). When the thermometer is activated via a momentary contact switch, the unit enters normal operation mode. In normal operation mode, the radio is active and connects with the user's SmartTemp app on their device. The temperature measurement is then communicated to the SmartTemp app.

6. Indications for Use:

The VDT985US Vicks® SmartTemp™ Thermometer is indicated for the intermittent measurement and monitoring of human body temperature orally, rectally or under the arm. It can be used on people of all ages except preterm babies or very small (for gestational age). This thermometer is intended to be used with Apple and Android mobile devices. It is intended for household use only.

7. Validation Results:

Clinical Study to show substantial equivalence:_A comparison study and clinical repeatability testing was performed on the following four age groups: 0-12 months, 12 months- <5 years, 5 years- <18 years, and 18 years and older in accordance with ASTM E1112-00(2006) and Clinical section (Appendix A) of ASTM E1965 to compare the VDT985US Vicks® SmartTemp™ Thermometer (test thermometer) with the predicate device, the Vicks V966 Thermometer (K043110). The reference or the qold standard used was the Welch Allyn SureTemp® Plus in the monitoring mode (K030580). This clinical comparison study demonstrated that the VDT985US Vicks® SmartTemp™ Thermometer is as good as (non-inferior or substantially equivalent to) the previously approved Vicks V966 Thermometer (K043110) in all age groups with respect to the bias and standard deviation in comparison to the reference Welch Allyn SureTemp® Plus in the monitoring mode (K030580). The temperatures obtained with the test Thermometer were highly related when compared to the predicate device. The clinical bias with stated uncertainty and clinical repeatability as defined in the ASTM E1112 standard were within clinical acceptability limits in accordance with the protocol (bias less than predicate device when compared to reference). The clinical repeatability of the test thermometer was statistically and clinically acceptable (less than 0.3 °C or 0.58°F).

8. Similarities/Differences of the proposed candidate device when compared to the predicate:

8.1 Intended Use

The predicate device, the Microlife MT18l1 Thermometer (K043110) is also intended for the intermittent determination of the human's body temperature for people of all ages. The intended use and indications for use of the MT18I1 Thermometer (predicate) and the VDT985US Vicks® SmartTemp™ Thermometer are similar. In addition, the WT1701

{5}------------------------------------------------

Raiing Company Wireless Thermometer (K132761) uses the wireless feature that is similar to the VDT985US Vicks® SmartTemp™ Thermometer Bluetooth wireless feature. The predicate device MT18l1 as well as the KAZ VDT985US Vicks® SmartTemp™ Thermometer uses the oral, axillary and rectal as the measurement site.

8.2 Materials

Materials used in the manufacture of the VDT985US Vicks® SmartTemp™ Thermometer are similar (derived from similar resins) to the predicate device. All skin contacting materials used in the new thermometer have been tested successfully for biocompatibility (cytotoxicity in accordance with ISO 10993-5 as well as irritation and sensitization in accordance with ISO 10993-10) and FDA Blue book memo G 95-1 for both thermometers.

8.3 Design

The industrial design of the VDT985US Vicks® SmartTemp™ Thermometer is similar to the predicate device, the Microlife MT1811 Thermometer (K043110), except for a new outer shell.

8.4 Operational Principles

The VDT985US Vicks® SmartTemp™ Thermometer is a handheld device, containing an On/Off switch, sensor area, microcontroller to control the device and take measurements. The operating principle is based on conduction of heat to a thermistor based sensor and use of predictive algorithms to estimate the body temperature.

8.5 Technology

The technology of the VDT985US Vicks® SmartTemp™ Thermometer is identical to the predicate device MT18I1. The bluetooth feature is an additional feature similar to the predicate WT701.
