Assessing Face Validity of the HexCom Model for Capturing Complexity in Clinical Practice : a Delphi study

Funding: This research was funded by INSTITUT CATALÀ DE LA SALUT, grant number 7Z19/008.Capturing complexity is both a conceptual and a practical challenge in palliative care. The HexCom model has proved to be an instrument with strong reliability and to be valid for describing the needs and strengths of patients in home care. In order to explore whether it is also perceived to be helpful in enhancing coordinated and patient-centred care at a practical level, a methodological study was carried out to assess the face validity of the model. In particular, a Delphi method involving a group of 14 experts representing the full spectrum of healthcare professionals involved in palliative care was carried out. The results show that there is a high level of agreement, with a content validity index-item greater than 0.92 both with regard to the complexity model and the HexCom-Red, HexCom-Basic, and the HexCom-Clin instruments, and higher than 0.85 regarding the HexCom-Figure and the HexCom-Patient instruments. This consensus confirms that the HexCom model and the different instruments that are derived from it are valued as useful tools for a broad range of healthcare professional in coordinately capturing complexity in healthcare practice

Gender and observed complexity in palliative home care : A prospective multicentre study using the hexcom model

This study analyses gender differences in the complexity observed in palliative home care through a multicentre longitudinal observational study of patients with advanced disease treated by palliative home care teams in Catalonia (Spain). We used the HexCom model, which includes six dimensions and measures three levels of complexity: high (non-modifiable situation), medium (difficult) and low. Results: N = 1677 people, 44% women. In contrast with men, in women, cancer was less prevalent (64.4% vs. 73.9%) (p < 0.001), cognitive impairment was more prevalent (34.1% vs. 26.6%; p = 0.001) and professional caregivers were much more common (40.3% vs. 24.3%; p < 0.001). Women over 80 showed less complexity in the following subareas: symptom management (41.7% vs. 51,1%; p = 0.011), emotional distress (24.5% vs. 32.8%; p = 0.015), spiritual distress (16.4% vs. 26.4%; p = 0.001), socio-familial distress (62.7% vs. 70.1%; p = 0.036) and location of death (36.0% vs. 49.6%; p < 0.000). Men were more complex in the subareas of "practice" OR = 1.544 (1.25-1.90 p = 0.000) and "transcendence" OR = 1.52 (1.16-1.98 p = 0.002). Observed complexity is related to male gender in people over 80 years of age. Women over the age of 80 are remarkably different from their male counterparts, showing less complexity regarding care for their physical, psycho-emotional, spiritual and socio-familial needs

Complejidad asistencial y lugar de muerte en atención domiciliaria paliativa

Resumen: Objetivo: Examinar las asociaciones entre las dimensiones del modelo de complejidad asistencial HexCom y la ubicación de la muerte. Método: Estudio observacional longitudinal multicéntrico en pacientes con enfermedad avanzada tratados por los equipos de soporte a la atención domiciliaria en Cataluña. Se recogieron edad, sexo, estado funcional y cognitivo, tipo de enfermedad, cuidador/a principal, trabajador/a familiar, lugar de la muerte y complejidad tras la primera visita. Se realizó un análisis de regresión de Cox multivariante. Resultados: Participación de 1527 pacientes (72% oncológicos), atendidos una mediana de 35 días. El 45% fallecieron en su domicilio. La probabilidad de morir en casa era mayor cuando se detectaba un mayor deterioro funcional (hazard ratio [HR]: 7,67; intervalo de confianza del 95% [IC95%]: 4,93-11,92), cuando el sujeto era varón (HR: 1,19; IC95%: 1,02-1,39), cuando la edad era >80 años (HR: 1,41; IC95%: 1,20-1,66) y cuando se detectaba complejidad en relación a la situación de últimos días (HR: 2,24; IC95%: 1,69-2,97). Era más probable no morir en casa si se padecía cáncer (HR: 0,76; IC95%: 0,64-0,89), si se detectaba un pobre apoyo externo al grupo familiar (HR: 0,79; IC95%: 0,67-0,93), si el/la paciente no se sentía en paz con los demás (HR: 0,54; IC95%: 0,39-0,75) o si había falta de acuerdo en la planificación del lugar de la muerte (HR: 0,57; IC95%: 0,48-0,68). Conclusiones: La valoración de la complejidad asistencial a través del modelo HexCom-Clin puede contribuir a una mejor planificación anticipada de decisiones al incorporar entre sus dimensiones el sentirse en paz con los demás, el soporte externo al núcleo familiar y el grado de acuerdo sobre el lugar de muerte. Abstract: Objective: To examine the associations between the dimensions of the HexCom care complexity model and the place of death. Method: Multicenter longitudinal observational study in patients with advanced illness cared for by home care support teams in Catalonia. Age, gender, type of illness, main caregiver, external support, place of death and the sub-areas of care complexity provided by HexCom were registered. A multivariate Cox regression analysis was performed. Results: Participation of 1527 patients (72% oncology), cared for a median of 35 days. 45% died at home. The probability of dying at home was greater when a greater functional impairment was detected in the initial assessment (hazard ratio [HR]: 7.67; 95% confidence interval [95%CI]: 4.93-11.92), when the patient was male (HR: 1.19; 95%CI: 1.02-1.39), was over 80 years old (HR: 1.41; 95%CI: 1.20-1.66) and when care complexity was detected in relation to being in a situation of last days (HR: 2.24; 95%CI: 1.69-2.97). It was more likely not to die at home in the case of cancer (HR: 0.76; 95%CI: 0.64-0.89), or if poor external support to the family group was detected in the first evaluation (HR: 0.79; 95%CI: 0.67-0.93), or that the patient did not feel at peace with others (HR: 0.56; 95%CI: 0.40-0.79), or lack of agreement on the planning of the place of death (HR: 0.57; 95%CI: 0.48-0.68). Conclusions: The assessment of the complexity of care through the HexCom-Clin model can help to improve advance planning of decisions by incorporating among its dimensions the feeling of peace with others, the external support to the family nucleus and the degree of agreement on the place of death
