Patients do not follow doctors’ instructions for all sorts of reasons (see lectures on attitudes and KAP), but usually not because they are dissatisfied. However, there is evidence that patients doctor shop (consulting more than one doctor during the same episode of illness, and often obtaining multiple, duplicate or unnecessary medications) when they are dissatisfied, and several studies have reported dissatisfaction with information giving by HK doctors. There is a link between the satisfaction with information given to cancer patients, the DPR and the patients’ reported QoL.
