'Just so you know, the patient is staff': healthcare professionals' perceptions of caring for healthcare professional-patients.

OBJECTIVE: To explore healthcare professionals' conceptions of the care of patients who are also healthcare professionals. DESIGN: Explorative, with a qualitative, phenomenographic approach. PARTICIPANTS AND SETTING: 16 healthcare personnel within different professions (doctors, nurses, assistant nurses, physiotherapists, occupational therapists) were interviewed about the care of 32 patients who were themselves members of different healthcare professions, in one healthcare organisation in Sweden. RESULTS: The care of patients who are healthcare professionals was conceived in five different ways, as: usual, dutiful, prioritised and secure, insecure and responsive. An initial conception was that their care was usual, just as for any other patient, and also a perceived duty to treat them and to protect their right to be a patient--as any other patient. Exploring further, informants described that these patients did receive secure and prioritised care, as the informants experienced making a greater commitment, especially doctors giving privileges to doctor-patients. A conception of insecure care infused the informants' descriptions. This comprised of them feeling intimidated in their professional role, feeling affected by colleagues' stressful behaviour and ambiguity whether the healthcare professional-patient could be regarded as a competent professional. The deepest way of understanding care seemed to be responsive care, such as acknowledging and respecting the patient's identity and responding to their wishes of how treatment was to be met. CONCLUSIONS: Caring for healthcare professionals seems to trigger different ethical approaches, such as deontology and ethics of care. According to ethics of care, the findings may indeed suggest that these patients should be cared for just as any other patients would be, but only if this means that they are cared for as persons, that is, they are given 'person-centred care'. This would imply balancing between acknowledging the vulnerable patient in the colleague and acknowledging the identity of the colleague in the patient.

Comparison of idarubicin and daunorubicin and their main metabolites regarding intracellular uptake and effect on sensitive and multidrug-resistant HL60 cells.

To study the effect of the main metabolites on the cytotoxic effect of daunorubicin and idarubicin in human HL-60 cells, drug-sensitive and multidrug-resistant HL60 cells were incubated with idarubicin and daunorubicin and their metabolites idarubicinol and daunorubicinol over a wide range of concentrations. The intracellular uptake of the drugs was determined by photofluorometry, and the cytotoxic effect in vitro was determined by a bioluminescence assay of intracellular adenosine triphosphate (ATP) after 4 days of culture in liquid medium. The effect of intracellular drugs was calculated from the incubation-concentration versus intracellular-uptake and cytotoxic-effect curves. The intracellular uptake of idarubicin was 6 times that of daunorubicin in drug-sensitive cells and 25 times higher in resistant cells. For idarubicinol as compared with daunorubicinol the corresponding factors were 25 and 7, respectively. As compared with the parent substances, the uptake of idarubicinol and daunorubicinol was 16% and 4%, respectively, in sensitive cells and 40% and > 100%, respectively, in resistant cells. An intracellular concentration of 0.5 nmol/mg protein of both parent substances caused a 50% growth inhibition in drug-sensitive cells as compared with 10 nmol/mg protein for drug-resistant cells. For the metabolites an intracellular concentration of 0.4 nmol/mg protein of idarubicinol and 2.0 nmol/mg protein of daunorubicinol was required to inhibit cells' growth by 50% in drug-sensitive HL60 cells. In the resistant HL60 cells the corresponding values were 30 nmol/mg protein for idarubicinol and 40 nmol/mg protein for daunorubicinol. These results confirm that idarubicinol may significantly contribute to the clinical effect of idarubicin. However, in combination with previous results that have shown low intracellular concentrations of the metabolites in vivo, it appears that the pharmacokinetic properties of the mother substances provide the major explanation for the clinical effect of idarubicin.
