Shared decision-making in scaling and root planing

Estimate proportion of various approaches used by dental hygienists for engaging patients in decisions commonly arising during scaling and root planing. Distribution of approaches was compared across various task components in this procedure, practice experience of dental hygienists and patient compliance.

Survey of graduates from and students in a baccalaureate dental hygiene program.

Paternalism (tell then do) and informed consent (give choices and reasons and ask for permission) were more common than shared decision-making (discuss alternatives, solicit patient input and arrive at a mutual decision) and disengagement (patient refusing offered service or avoiding further involvement) by a ratio of 4 to 1 for the first 2 compared with the latter 2. This relationship was held across selecting treatment, procedural adjuncts, homecare instructions and financial arrangements. Dental hygienists exhibited a range of personal preferences for engagement approaches. No-show rate, patient disengagement outside the office, was high (20%).

Dental hygienists reported using 'more controlled' approaches to engaging patients in decisions regarding treatment. Patients may prefer to engage in more shared decisions and choose this approach by staying away from the office. This may underestimate patients' decisions to stay away from treatment, for example by not showing for completion of the treatment or disregarding homecare routines.
