Not all questions concerning therapeutic effects in medical research can be answered satisfactorily by standard trials. The stepped wedge cluster design is a special form of randomised study in which an intervention at group level is implemented in stages. ⋯ The statistical analysis of cluster trials should account for the fact that individuals within clusters may show many similarities. Ethical aspects of stepped wedge design should be considered carefully, especially when obtaining individual informed consent is not possible.

Vaccination against the human papilloma virus (HPV) has been included in the national Vaccination Programme of the Netherlands for 12-year-old girls since 2010. Vaccination coverage for the birth cohort of 1997 was 56.; there is a gradual increase in uptake. Continuous safety monitoring brought no new unknown serious side effects to light; many girls suffered from transient symptoms such as painful arm, fatigue and headache. ⋯ HPV vaccination of 12-year-old girls is cost-effective, even for relatively low vaccination coverage. The potential protection of HPV vaccination extends beyond prevention of cervical cancer by preventing other oncological manifestations of HPV infection in women as well as men and genital warts. The preventive HPV vaccines do not appear to be effective in treating existing abnormalities.

A good performance indicator reflects the quality of care and uses clinical outcomes. When outcomes are difficult to obtain, process and structure variables can provide a good picture of quality of care. ⋯ There are limitations to the use of performance indicators to compare hospitals; these include correction for case mix, the statistical reliability of the measurements and the validation of performance indicators. Well-considered performance indicators can be used to monitor trends and identify providers that perform below a certain benchmark, but not to rank them.
