ONS Guidelines™ to Support Patient Adherence to Oral Anticancer Medications.

Most recommendations are conditional and based on very low certainty evidence, so the true effect may be smaller or absent. The underlying studies varied widely in cancer type, medication regimen, intervention content, and usual care. Results may not apply to one patient. Several interventions were bundled with education, coaching, follow-up, or technology support, so the contribution of any single component cannot be separated. No standardized adherence risk assessment tool or ongoing assessment frequency was identified. The guideline does not replace clinician care or guarantee improved outcomes. Implementation needs staff time, coordination, training, and reimbursement, which may be hard to justify in smaller practices. The panel made no recommendation for technology because evidence was a knowledge gap.

The guideline panel had no relevant conflicts of interest. The supplied article metadata lists non-U.S. government and NIH extramural research support.

Do not read these conditional recommendations as proof that any single intervention works. Most evidence is very low certainty, and several interventions were delivered together with education, coaching, or follow-up, so the effect of any one part cannot be separated.
