Finding ways to cultivate positive working relationships is essential for ensuring excellent patient care standards. In this study we sought to identify barriers to an effective working relationship between physicians (both obstetricians and family physicians) and midwives, and to find ways to improve the quality of professional interactions and promote team-based pregnancy care. We conducted a mail survey within the former Calgary Health Region that included questions about professional interaction, philosophy regarding childbirth, and relationships between obstetrical practitioners. Participants included family physicians (FPs), midwives (MWs), and obstetricians (OBs) who were identified from publicly available lists. The overall response rate was 80% (144/180). Eligible responses were received fro...

Our paper discusses the ethical issues associated with the early marketing and use of new surgical devices from the perspectives of the six groups most concerned. Health Canada, which is responsible for licensing new surgical devices, should amend their requirements to include rigorous clinical trials that provide data on effectiveness and safety for each new product before it is marketed. Industry should comply with all Health Canada requirements to obtain licenses for new products. Until Health Canada requires effectiveness and safety data, industry should cooperate with physicians in appropriate studies before releasing new products and should make balanced presentations of all the available evidence. Surgeons should, before using a new surgical device, assess the evidence on its effectiveness and safety and ensure they are properly trained and competent in using the device. Surge...

Women were eligible if they had undergone vaginal repairs for any degree or type of POP with no anti-incontinence procedure between July 1, 2004 and June 30, 2006, and had been continent preoperatively, as defined by a negative cough stress test with or without reduction of prolapse. Demographic, preoperative, operative, and postoperative data were retrieved from hospital charts. The incidence of postoperative SUI (POSUI) and its quality of life (QoL) impact were assessed by mailed questionnaire. The POSUI endpoint was defined by the report of SUI symptoms on the mailed questionnaire and/or affirmation of postoperative treatment for SUI. Forty-two out of 100 respondents reported POSUI within the 2-year average follow-up period. Twelve of 37 symptomatic women (32%) were moderately or greatly bothered by their symptoms. The QoL impact score was generally low but was statistically greater in women with POSUI compared to those with no POSUI (13 vs. 3, P=0.0006). The risk of POSUI following vaginal repairs of POP may be higher than previously reported and approximately one-third of women are bothered by these symptoms. These findings deserve further investigation.

Participants included 61 women who underwent laparoscopy for nonacute pain (n = 61). A second group of 16 women who had undergone tubal ligation was included to explore whether laparoscopy induced a painful postoperative response in women without preoperative pain. Subjective tests included numeric pain scale, pain catastrophizing scale, depression scale, global assessment of change, and the McGill Pain Questionnaire Short Form. Quantitative sensory testing included abdominal cutaneous allodynia, trigger points, and reduced pain thresholds. The nonacute pain sample had 80% power to detect a difference of 0.5 standard deviation in average pain levels. Analysis included parametric and nonparametric comparisons of groups and univariate and linear regression analysis of clinically relevant variables. In women who underwent tubal ligation, pain levels were low before and after the procedure. In women who underwent surgery for nonacute pain, pain levels at 6 months and all psychologic test scores were reduced significantly compared with baseline (P < .001 and P = .001, respectively). Among those women with positive results on the quantitative pain tests of sensitization at baseline, average postoperative pain was also significantly reduced (P < .001). Univariate analysis demonstrated only tests of sensitization that were correlated with change in average pain level (P = .01). Regression analysis suggested that baseline pain, catastrophizing, and the presence of cutaneous allodynia significantly predicted pain levels 6 months after surgery (P < .001). Pain after laparoscopic surgery for nonacute painful conditions can be predicted by baseline pain, catastrophizing, and the presence of allodynia, which is a simple swab test that indicates sensitization.

Recognizing HTA as a moral economy helps to explain when and why HTA professionals’ views of what HTA should and can do are mutable, and may specifically help to explain why there is resistance among some HTA professionals to the inclusion of ethical issues and patients or the public in technology assessment. The moral economy framework furthermore sheds light on the nature of objectivity in contemporary HTA.
