PainChek® only patches and maintains the latest public release of the PainChek App. Older builds do not receive security fixes, regulatory updates, or technical support. To ensure ongoing compliance and access to new features, we recommend that all users:
-
Upgrade to the current build - available now in the Apple App Store and Google Play Store as soon as possible.
-
Enable automatic app updates on their iOS or Android devices so the latest version is installed as soon as it becomes available, without manual intervention.
Note
If a serious defect is discovered in an old version, or if that version can no longer connect reliably to the PainChek® back-end, sign-in for that version may be disabled.
It is important to note that PainChek® is an observational pain assessment tool intended to assist trained healthcare professionals in assessing pain in non-verbal patients. As such, PainChek® results should be interpreted by qualified healthcare professionals within the context of their broader clinical knowledge and examination of the Resident.
In addition, PainChek® users should be aware that although PainChek® clinical study data support the accuracy of the device for identifying No Pain, Mild Pain, and Moderate Pain, a low number of residents were identified as suffering from Severe Pain. For this reason, there is uncertainty in the ability of the device to assess Severe Pain, given the small sample size.
Furthermore, when interpreting pain assessment results, users should be aware that the lower bounds of the 95% confidence intervals (CI) for performance across all pain severity categories, particularly Moderate and Severe Pain, indicate increased uncertainty. This uncertainty may be due to the small number of assessments in these categories and the limited test-retest reliability of the clinical comparator used (the Abbey Pain Scale). These factors may have contributed to the observed lower confidence bounds.
It is also important to note that PainChek® clinical data were evaluated to determine whether facial expressions associated with pain are consistent across racial groups. Although the study population consisted of a less diverse population than that of the United States, the study findings and evidence from published research support the conclusion that core facial expressions of pain are consistent across racial and ethnic groups.
PainChek® is not a substitute for the clinical judgment or assessment by a qualified healthcare professional, who may decide that PainChek® is not appropriate for some Residents.
