Background and Aims Patients receiving nursing care at home require a needs assessment. There are indications that practice variation exists in needs assessments performed by Dutch home care nurses. One possible cause is that nurses are differentially influenced by others when performing needs assessments. Instruments recommending what is appropriate care have the potential to protect nurses against unwarranted influences. In the Netherlands, a framework exists including general norms about performing needs assessments. We aimed to achieve insight into whether nurses, who have heard of the framework, feel more free to assess the care that is needed for their patients, and whether other actors play a role in performing needs assessments. Methods An online questionnaire was sent to members of the Dutch Nursing Staff Panel (response 47%; n = 302) in November 2019. Only nurses who perform needs assessments were included in the analyses (n = 141). χ2‐tests were used to assess the relationships between the variables of having heard of the framework, feeling free to assess the care that is needed, and the influences of others. Results We found no relationships between having heard of the framework and feeling free to assess the care that is needed for patients or reporting influence of others. However, home care nurses who state that they are not influenced by others, feel more free to assess the care that is needed for their patients. In contrast, those who state that they are influenced by informal caregivers, or health care insurers, feel less free to assess the care that is needed. Conclusion It appears that the framework for performing needs assessments does not, in its current form, protect against influences of others. Further research is recommended to examine what kind of instruments nurses need to perform unambiguous and good needs assessments and, as such, reduce unwarranted practice variation.

AimTo describe a Delphi study regarding practice variation in needs assessment by Dutch home care nurses, to define practice variation in home care nursing and explore which factors may have a role in this needs assessment.DesignA Delphi study was conducted with the participation of home care representatives.MethodA Delphi questionnaire was developed, preceded by literature research and an expert meeting. The Delphi study took place between December 2020 and February 2021. The goal was to achieve a consensus level of at least 70%.ResultsAfter three rounds, 32 experts reached a consensus about definitions regarding variation in needs assessment, warranted and unwarranted variation. In total, 59 factors were determined related to (1) the client and health, (2) the clients' context, (3) nurses and (4) the nurses' context. Thirty‐four factors scored warranted of influence and 18 (of 34) were client related. Most of the factors that scored unwarranted influencing needs assessment (17 of 26) were related to the home care nurses' context.ConclusionHaving a consensus about the definition of practice variation in needs assessment and possible influencing factors support the professionals to discuss and improve the unity and quality of their decision‐making process in home care. This may contribute to more righteous care for clients in need of home care.ImpactSince 2015, home care nurses in the Netherlands are responsible for determining the amount, type and duration of care for clients in need of home care. This so‐called needs assessment legitimizes the payment by health insurers. Signals of practice variation in needs assessment are heard in home care field. Although practice variation may be justified, it can lead to over or underuse of care, which may affect clients' outcomes. If we can identify influencing factors and find patterns that contribute to practice variation, we might gain a better understanding of the process and improve home care.Patient or public contributionIn this study, there was no patient or public involvement. Client representatives were included in this research as experts in the home care field, and they participated in three rounds of the Delphi study. They contributed by sharing their expert opinion on the definitions presented and the factors possibly influencing needs assessment.
