title: Further studies on the coordination chemistry of [Pt₂(μ-S)₂(PPh₃)₄] towards indium(III) substrates

authors: Henderson, William

subjects: Platinum complexes

abstract: The reactivity of the metalloligand [Pt₂(μ-S)₂(PPh₃)₄] towards a variety of indium(III) substrates has been explored. Reaction with excess In(NO₃)₃ and halide (KBr or NaI) gave the four-coordinate adducts [Pt₂(μ-S)₂(PPh₃)₄InX₂]⁺[InX₄]⁻ (X = Br, I). An X-ray structure determination on the iodo complex revealed a slightly distorted tetrahedral coordination geometry at indium. In contrast, reaction of [Pt₂(μ-S)₂(PPh₃)₄] with indium(III) chloride was more complex; the ion [Pt₂(μ-S)₂(PPh₃)₄InCl₂]⁺ was initially observed in solution (using ESI mass spectrometry), and isolated as its BPh₄⁻ salt. Analysis of [Pt₂(μ-S)₂(PPh₃)₄InCl₂]⁺[BPh₄]⁻ by ESI MS showed the parent cation when analysed in MeCN solution. However in solutions containing methanol, partial solvolysis occurred to give the di-indium species [{Pt₂(μ-S)₂(PPh₃)₄InCl(OMe)}₂]²⁺ (proposed to contain an In₂(μ-OMe)₂ unit with five-coordinate indium) and its fragment ion [Pt₂ (μ-S)₂(PPh₃)₄InCl(OMe)]⁺. Reaction of [Pt₂(μ-S)₂(PPh₃)₄] with InCl₃•3H₂O, 8-hydroxyquinoline (HQ) and trimethylamine in methanol gave the adduct [Pt₂(μ-S)₂(PPh₃)₄InQ₂]⁺, isolated as its PF₆⁻ salt. The same cationic complex is formed when [Pt₂(μ-S)₂(PPh₃)₄] is reacted with InQ₃ in methanol, but in this case the product is contaminated with the mononuclear complex [(Ph₃P)₂PtQ]⁺ formed by disintegration of the trinuclear complex [Pt₂(μ-S)₂(PPh₃)₄InQ₂]⁻ with byproduct Q⁻. [(Ph₃P)₂PtQ]⁺BPh₄⁻ was independently prepared from cis-[PtCl₂(PPh₃)₂] and HQ/Me₃N, and is the first example of a platinum 8-hydroxyquinolinate complex containing phosphine ligands.

title: Exploring patient experiences and power dynamics in an acute general surgical ward: A mixed methods study exploring patient and staff perceptions of the inpatient experience at Waikato Hospital

authors: Drake, Emma

subjects: Patient-centred models of care

abstract: Background: Alongside health outcomes, patient experiences are considered crucial in identifying the quality of a health care setting. General surgery comprise the largest range of pathologies and accounts for the highest number of patient discharges of any surgical specialty. As a way to address the power imbalance between healthcare staff and patients, patient-centred models of care are increasingly being adopted and implemented within hospitals including surgery. This study aims to investigate the current experiences of acutely admitted patients in a general surgical ward at Waikato Hospital, including opportunities for and challenges to improvement initiatives. Furthermore, the study examines relevant staff members perspectives of the inpatient experience and seeks to determine the efficacy of a proposed intervention focusing on empowering patients and their families.
Methods: The study was a mixed method design involving two phases. Phase I obtained qualitative data from semi-structured interviews with six patients and twelve staff members. Themes which emerged from the qualitative data in phase I were used to inform the development of phase II, as well as to inform a proposed patient self- assessment intervention. Phase II obtained quantitative data through Likert scale response surveys provided to acute patients on, or near to, their day of discharge from the surgical ward over a two month period.
Results: A total of six patients and 12 healthcare staff (senior registered nurses, n=3; surgical registered nurse managers, n=2; surgical fellows, n=2; surgical registrar, n=1; dietitian, n=1; social worker, n=1; occupational therapist, n=1; and physiotherapist n=1) were involved in phase I. A total of 53 surveys were returned from patients in Phase II (63.1% response rate). Qualitative data from phase I was analysed using a general inductive approach. This revealed three themes including power and control concerns for patients, the hierarchy of the health care team and the surrounding stressors of the organisation and environment. Analysis of the quantitative data collected descriptive statistics and calculated chi-squares. Of note were the statistically significant differences particularly between patients of Māori ethnicity comparatively to non-Māori, and according to gender and reason in hospital. There were no statistically significant differences for patients according to age group.
Conclusion: This study identified both the experiences of patients and staff in an acute general surgical context. The study found that the proposed patient self- assessment intervention was not immediately recommended. This was due to the current recommendations from patients who identified their strong preference was for face-to-face communication with staff. It was also due to staff members identification of a perceived inability to consistently provide person-centred care which corresponded with the patient self-assessment data. Acute general surgical care needs of patients were perceived by staff as taking precedent and current workplace stressors, including staffing and skill mix deficits and perceived lack of staff wellbeing supports, were strong inhibitors for staff to provide their preferred capacity of patient-centred care.
