Influences on place of death in Botswana

Objective: There is an emerging body of research aimed at understanding the determinants of place of death, as where people die may influence the quality of their death. However, little is known about place of death for people of Southern Africa. This study describes place of death (home or hospital) and potential influencing factors (cause of death, age, gender, occupation, and district of residence). Method: We collected the death records for years 2005 and 2006 for all adult non-traumatic deaths that occurred in Botswana, described them, and looked for associations using bivariate and multivariate analyses. Results: The evaluable sample consisted of 18,869 death records. Home deaths accounted for 36% of all deaths, and were predominantly listed with unknown cause (82.3%). Causes of death for hospital deaths were HIV/AIDS (49.7%), cardiovascular disease (13.8%), and cancer (6.6%). The mean age at the time of all deaths was 53.2 years (SD = 20.9); with 61 years (SD = 22.5) for home deaths and 48.8 years (SD = 18.6) for hospital deaths (p < .001). Logistic regression analysis revealed the following independent predictors of dying at home: unknown cause of death; female gender; >80 years of age; and residing in a city or rural area (p < .05). Significance of Results: A major limitation of this study was documentation of cause of death; the majority of people who died at home were listed with an unknown cause of death. This finding impeded the ability of the study to determine whether cause of death influenced dying at home. Future study is needed to determine whether verbal autopsies would increase death-certificate listings of causes of home deaths. These data would help direct end-of-life care for patients in the home.
