Approximately half of the nursing students confirmed their willingness to participate in caring for older people: a systematic review and meta-analysis

Global population aging poses a significant global challenge, necessitating an increased demand for proficient caregivers specialized in elderly care. In our study, a systematic review and meta-analysis were conducted to synthesize the evidence concerning nursing students’ willingness to participate in caring for older people. Eligibility criteria focused on cross-sectional studies involving nursing students’ willingness to participate in caring for older people and were reported in English or Chinese. PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), and WANFANG databases were searched from inception until July 24, 2022. The methodological quality assessment in the included studies was evaluated using the AHRQ instrument. The pooled effects of the nursing students’ willingness to participate in caring for older people were computed using a random-effects model. Funnel plots and Egger’s test were employed to evaluate publication bias. Meta-regression and subgroup analysis were performed to explore the sources of heterogeneity. Sensitivity analysis was conducted to verify the robustness of the meta-analysis findings. All statistical tests were conducted with Stata 16.0 software. A total of 68 studies of medium or high quality met the eligibility criteria, involving 30,328 nursing students. The rate of nursing students’ willingness to participate in caring for older people was 49.0% (95% CI = 46–53%, I2 = 98.1%, P = 0.000). The results of meta-regression analysis showed that the following four predictor variables were significantly associated with nursing students’ willingness to participate in caring for older people: experience of living with and caring for older people, nursing as their first choice and their year-level in education, respectively. Subgroup analyses for these four predictor variables revealed the following pooled estimates of nursing students’ willingness: having experience of living with older people (0.54, 95% CI = 0.46–0.62) vs. no such experience (0.38, 95% CI = 0.30–0.46), having experience of caring for older people (0.55, 95% CI = 0.48–0.63) vs. no such experience (0.38, 95% CI = 0.30–0.46), nursing as their first choice (0.54, 95% CI = 0.51–0.58) vs. not their first choice (0.44, 95% CI = 0.35–0.53), being in the first year of nursing education (0.44, 95% CI = 0.34–0.55), second year (0.45, 95% CI = 0.34–0.56), and third and fourth year (0.62, 95% CI = 0.53–0.71). The study found that approximately half of the nursing students confirmed their willingness to participate in caring for older people.The present study can serve as a resource for policymakers to increase the willingness of nursing students to participate in caring for older people.
