Analysis of medical malpractice claims to improve quality of care: Cautionary remarks

Medical malpractice claims can be analysed to gain insights aimed at improving quality of care. However, using medical malpractice claims in medical research raises epistemological and methodological concerns related to certain features of the litigation process. Medical research should therefore approach medical malpractice claims with caution. Taking one recent study as a an example, this article insists on three areas of concern: (a) the quantity of legal materials available for analysis; (b) the content of the legal materials available for analysis; and (c) the ways in which the content of the legal materials should be analysed and the types of inferences that it can support. The article concludes with general recommendations for future medical research that would incorporate medical malpractice claims. These recommendations centre around recognizing the qualitative dimension of legal reasoning.     

The student experience of clinical supervision across health disciplines – Perspectives and remedies to enhance clinical placement

Effective clinical practice supervision for health students is essential prior to commencing their respective professions. Students require adequate preparation before their clinical practice event with an experienced clinical supervisor able to impart professional ‘know how’ and skills to students. The purpose of this study was to describe final year health students' perspectives and experiences of clinical supervision, and to develop an interprofessional model of clinical supervision. Focus groups and semi-structured interviews were conducted with undergraduate health students across a range of disciplines. Some students provided email comments. Qualitative data was analysed thematically using NVivo (V11). Six key themes and their various sub-themes (refer Table 1) were identified: (1) undergraduate learning valued by the CP provider; (2) effective connections (communications) between student, CS, CP provider and university; (3) undergraduate student learning not being valued; (4) ineffective connections; (5) mitigating factors for students; and (6) the impact of increasing student numbers. Undergraduate health student clinical placement requires careful educational preparation, structuring and adequate support for both the student undergoing the practice event and for the clinical supervisor stewarding the undergraduate health professional. A prospective plan to ensure an excellent experience is required (Fig. 1).

Barrier Method Preferences and Perceptions Among Zimbabwean Women and their Partners

In Zimbabwe, adult HIV prevalence is over 25% and acceptable prevention methods are urgently needed. Sixty-eight Zimbabwean women who had completed a barrier-methods study and 34 of their male partners participated in focus group discussions and in-depth interviews to qualitatively explore acceptability of male condoms, female condoms and diaphragms. Most men and about half of women preferred diaphragms because they are female-controlled and do not detract from sexual pleasure or carry stigma. Unknown efficacy and reuse were concerns and some women reported feeling unclean when leaving the diaphragm in for six hours following sex. Nearly half of women and some men preferred male condoms because they are effective and limit women's exposure to semen, although they reportedly detract from sexual pleasure and carry social stigma. Female condoms were least preferred because of obviousness and partial coverage of outer-genitalia that interfered with sexual pleasure.     

A closed system for the clinical banking of umbilical cord blood

Umbilical cord blood (UCB) is a source of hematopoietic progenitor cells and is used as an alternative to the bone marrow or peripheral blood for treatment of several onco-hematological diseases. Because of the limited number of CD34+ hematopoietic stem cells present in UCB units and of the elevated costs of cryopreservation, it is of paramount importance to select the UCB units that are clinically useful before storage and optimize banking efficiency by designing reliable procedures to process and freeze the selected units. Among the different parameters characterizing UCB, nucleated cell (NC) and CD34+ cell content provides useful criteria to select UCB units since clinical data documented that the infused cell load (both NC and CD34+ cells) plays an important role in the successful outcome of transplants. By evaluating volume, CD34+ cell content, NC total amount, and NC density of 117 UCB units, we found a significant association between CD34+ cell content and NC density and total amount, indicating these parameters as useful to decide UCB clinical utility. Furthermore, we set up a fast procedure to process UCB units for storage. A system for NC separation and volume reduction of UCB samples in a dedicated, germ-free, closed circuit was developed, where plasma and red blood cells (RBC) depletion was obtained by sedimentation in the presence of a 3.5% Polygeline solution. By this separation system, both RBC depletion and high NC and CD34+ cell recoveries were achieved in 60 min, and the yield was comparable to the one obtained by other separation methods. Since Polygeline has been clinically used as a plasma expander and no toxic effects on patients were reported, the protocol can be applied in the large-scale banking of UCB.
