ABSTRACT

In Northern European countries 13-28% of female patients seeking gynecological health care have reported abuse by health care staff (AHC). We conducted workshops with health care staff using the improvised role-play method Forum Play (FP), based on techniques developed by Boal. The study explores to what extent the intervention increased the staff's awareness of AHC and their ability to take action against it. A total of 16 half-day FP workshops were conducted with staff from a Swedish women's clinic over one year. Self-reported questionnaires were distributed to all staff before, during, and after the intervention. Primary outcome measures were the number of reported occasions of AHC and FP participants' ability to act in AHC-situations. We found an increase in the participants' self-reported ability to act in AHC-related situations. However, no change could be observed in the number of reported occasions of AHC between baseline and one year after the intervention. Health care staff's participation in workshops using improvised role-play can increase staff's perceived ability to take action in AHC situations. The voluntary nature of the intervention may have attracted those who were already aware of the topic, and likely explains the unchanged awareness of AHC.

ABSTRACT

BACKGROUND: There is a growing body of international research that displays the prevalence and character of abuse in health care. Even though most of these studies are conducted from a patient perspective little is known about how patients conceptualize their agency in relation to such situations. This study aimed to explore how patients reason about their potential to act in abusive situations. METHODS: Qualitative interviews were conducted with thirteen patients in Sweden. Central in the interviews were three comics, inspired by Boal's Forum Theatre and part of an earlier online intervention study in which the informants had participated. Each comic showed a situation in which a patient feels abused, and on the opposite side were suggestions for how the patient could act in response. Informants were asked to reflect about situations of abuse and in specific upon the comics. We used the methodology of constructivist grounded theory throughout the study, including the analysis. RESULTS: It appeared that the informants constantly re-negotiated their and other patients' agency in relation to the specifics of the event, patients' and staff's responsibilities, and the patients' needs and values. This process questions views of agency as fixed and self-evident, and can be understood as part of changing discourses about patients' social role and possibilities to organize their care. Using a feminist theory of power we expected the informants to elicit instances of resistance to domination, which is central to the comics. While doing that, the informants also hinted at parallel stories of empowerment and less visible forms of agency in spite of domination. CONCLUSION: The current analysis showed different ways in which the informants constantly re-negotiated their agency in potentially abusive situations. Not only did the informants engage in reflections about immediate responses to these untoward situations, they also engaged in thoughts about strategies that could protect them and counteract abuse in health care over the long-term. This opens up for future research into ways patients organize their care and identify threats and barriers to the care they need, which could be valuable knowledge for care quality improvement.

ABSTRACT

Electrical injection lasers emitting in the 1.3 µm wavelength regime based on (GaIn)As/Ga(AsSb)/(GaIn)As type-II double "W"-quantum well heterostructures grown on GaAs substrate are demonstrated. The structure is designed by applying a fully microscopic theory and fabricated using metal organic vapor phase epitaxy. Temperature-dependent electroluminescence measurements as well as broad-area edge-emitting laser studies are carried out in order to characterize the resulting devices. Laser emission based on the fundamental type-II transition is demonstrated for a 975 µm long laser bar in the temperature range between 10 °C and 100 °C. The device exhibits a differential efficiency of 41 % and a threshold current density of 1.0 kA/cm2 at room temperature. Temperature-dependent laser studies reveal characteristic temperatures of T0 = (132 ± 3) K over the whole temperature range and T1 = (159 ± 13) K between 10 °C and 70 °C and T1 = (40 ± 1) K between 80 °C and 100 °C.

ABSTRACT

BACKGROUND: Increasing attention to patients' rights and their ability to choose their healthcare provider have changed the way patients can respond to untoward, disempowering and abusive healthcare encounters. These responses are often seen as crucial for quality improvement, yet they are little explored and conceptualized. OBJECTIVE: To explore patients' potential responses to untoward healthcare encounters and looking at their possible consequences for care quality improvement as well as for the individual patient. RESEARCH DESIGN: The article is structured looking at two primary strategies: patient exit (leaving a healthcare provider) and patient voice (expressing grievances), derived from Hirschman (1970). These strategies were explored by the use of theoretical and empirical literature and applied to an individual patient case. The case functions as a pedagogical tool to illustrate and problematize what exit and voice strategies can mean for a single patient. Ethical considerations: The patient case is my version of a generalized scenario that is described elsewhere. It does not represent an individual patient's story, but aims to be realistic and recognizable. FINDINGS AND CONCLUSION: Based on the existing literature, it is hypothesized that, in their current form, exit and voice strategies have a limited effect on care quality and can come at a price for patients. However, both strategies may be of value to patients and providers. Therefore, the healthcare system could empower patients to engage in action and could further develop ways for providers to effectively use patients' responses to improve practice and find ways to prevent patients from untoward experiences in healthcare.

ABSTRACT

Patients' experiences of orgasm changes and loss of ejaculation after radical prostatectomy   In this study we report on men's experiences of orgasm changes and loss of ejaculation after radical prostatectomy. Ten men, all recruited through a Swedish hospital, were interviewed and data was analyzed using qualitative content analysis. The results showed that the experience of orgasm has weakened but that the loss of ejaculation was not perceived as a loss per se. However, the risk of urine release during orgasm was troublesome and inhibiting. These challenges were framed within an existential narrative about sexuality, as expressed in preoperative sexual farewell rituals and postoperative feelings of ambivalence and regret. These findings can be used in the design of patient information and for sexual rehabilitation treatment.

ABSTRACT

As health care exists to alleviate patients' suffering it is unacceptable that it inflicts unnecessary suffering on patients. We therefore have developed and evaluated a drama pedagogical model for staff interventions using Forum Play, focusing on staff's experiences of failed encounters where they have perceived that the patient felt abused. In the current paper we present how our preliminary theoretical framework of intervening against abuse in health care developed and was revised during this intervention. During and after the intervention, five important lessons were learned and incorporated in our present theoretical framework. First, a Forum Play intervention may break the silence culture that surrounds abuse in health care. Second, organizing staff training in groups was essential and transformed abuse from being an individual problem inflicting shame into a collective responsibility. Third, initial theoretical concepts "moral resources" and "the vicious violence triangle" proved valuable and became useful pedagogical tools during the intervention. Four, the intervention can be understood as having strengthened staff's moral resources. Five, regret appeared to be an underexplored resource in medical training and clinical work.The occurrence of abuse in health care is a complex phenomenon and the research area is in need of theoretical understanding. We hope this paper can inspire others to further develop theories and interventions in order to counteract abuse in health care.

ABSTRACT

BACKGROUND: Abuse in health care organizations is a pressing issue for caregivers. Forum play, a participatory theater model, has been used among health care staff to learn about and work against abuse. This small-scale qualitative study aims to explore how forum play participants experience the potentials and limitations of forum play as an educational model for continued professional learning at a hospital clinic. METHODS: Fifteen of 41 members of staff of a Swedish nephrology clinic, primarily nurses, voluntarily participated in either one or two forum play workshops, where they shared experiences and together practiced working against abuse in everyday health care situations. Interviews were conducted after the workshops with 14 of the participants, where they were asked to reflect on their own and others' participation or nonparticipation, and changes in their individual and collective understanding of abuse in health care. RESULTS: Before the workshops, the informants were either hesitant or very enthusiastic toward the drama-oriented form of learning. Afterward, they all agreed that forum play was a very effective way of individual as well as collective learning about abuse in health care. However, they saw little effect on their work at the clinic, primarily understood as a consequence of the fact that many of their colleagues did not take part in the workshops. DISCUSSION: This study, based on the analysis of forum play efforts at a single hospital clinic, suggests that forum play can be an innovative educational model that creates a space for reflection and learning in health care practices. It might be especially fruitful when a sensitive topic, such as abuse in health care, is the target of change. However, for the effects to reach beyond individual insights and a shared understanding among a small group of participants, strategies to include all members of staff need to be explored.

ABSTRACT

UNLABELLED: Low tear production or elevated tear evaporation can lead to severe keratoconjunctivitis sicca. In patients with this disease, the transfer of an autologous submandibular gland into the temporal fossa is currently the most common surgical lacrimal gland substituting procedure. AIM: We compared the pre- and postoperative viability of transferred submandibular glands. PATIENTS, METHODS: Altogether 16 submandibular glands had been transferred in 12 patients. The graft's viability was evaluated before and 0.5-1, 1-6 and 8-12 months after transplantation by dynamic salivary gland scintigraphies after application of 40-50 MBq 99mTc-pertechnetate. Quantitative analysis was performed by calculation and comparison of the glandula submandibularis-to-background-ratio (SBR) and the transplant-to-background-ratio (TBR). The scintigraphic results were correlated with the clinical follow-up. RESULTS: All grafts remained viable during clinical follow-up. Salivary gland scintigraphy yielded 15 true positive results and 1 false-negative result. Comparison of presurgical SBR and postsurgical TBR showed good correlation with the clinical course. In 10 patients at least one transplant-reduction was necessary due to excessive epiphora occurring averagely 8 months after transplantation. CONCLUSION: Our results show that salivary gland scintigraphy very exactly reflects the morphological and biochemical postsurgical changes in a transferred submandibular gland. Thus, it is a reliable tool to exactly and objectively evaluate the viability of the grafts in the postsurgical course.

ABSTRACT

BACKGROUND: Efforts to counteract abuse in health care, defined as patient-experienced abuse, have mainly focused on interventions among caregivers. This study is the first to test an online intervention focusing on how patients can counteract such abuse. The intervention aimed at increasing patients' intention and perceived ability to act in future situations where they risk experiencing abuse. METHODS: Participants were recruited through a nephrology clinic in Sweden. The intervention consisted of an online program that aimed to stimulate patients to think of possible actions in situations in which they risk experiencing abuse. The program comprised stories and exercises in text and comic form. The participants filled out a questionnaire immediately before and after going through the program, as well as during follow-up four to eight weeks later. RESULTS: Forty-eight patients (39 %) participated in the study and spent, on average, 41 min responding to questions and going through the program. Both men and women, of various ages and educational backgrounds, participated. An increase in participants' self-reported ability to identify opportunities to act in a given situation was seen immediately afterwards, as well as during follow up. CONCLUSION: The current study suggests that it is feasible and most likely useful to a variety of patients to work with the provided material that has the aim of counteracting abuse in health care. It would be of interest to further develop ways of using comics and to test similar interventions in other health care settings.

ABSTRACT

The case of a 57-year-old woman with a rapidly growing unpigmented conjunctival tumor is presented. Despite the clinical appearance the histology surprisingly confirmed a malignant melanoma of the conjunctiva. Various phenotypes and the rareness of this disease complicate a clinical diagnosis. Therapeutically, a complete excision of the tumor including a safety margin, adjuvant topical chemotherapy and closely monitored follow-up are crucial.

ABSTRACT

BACKGROUND: In Sweden, 20% of female patients have reported lifetime experiences of abuse in any health care setting. Corresponding prevalence among male patients is estimated to be 8%. Many patients report that they currently suffer from these experiences. Few empirical studies have been conducted to understand what contributes to the occurrence of abuse in health care. OBJECTIVES: To understand what factors contribute to female patients' experiences of abuse in health care. DESIGN: Constructivist grounded theory approach. SETTINGS: Women's clinic at a county hospital in the south of Sweden. PARTICIPANTS: Twelve female patients who all had reported experiences of abuse in health care in an earlier questionnaire study. METHODS: In-depth interviews. RESULTS: The analysis resulted in the core category, the patient loses power struggles, building on four categories: the patient's vulnerability, the patient's competence, staff's use of domination techniques, and structural limitations. Participants described how their sensitivity and dependency could make them vulnerable to staff's domination techniques. The participants' claim for power and the protection of their autonomy, through their competence as patients, could catalyze power struggles. CONCLUSIONS: Central to the participants' stories was that their experiences of abuse in health care were preceded by lost power struggles, mainly through staff's use of domination techniques. For staff it could be important to become aware of the existence and consequences of such domination techniques. The results indicate a need for a clinical climate in which patients are allowed to use their competence.

ABSTRACT

OBJECTIVES: To identify which patient characteristics are associated with silence towards the healthcare system after experiences of abusive or ethically wrongful transgressive behaviour by healthcare staff. DESIGN: Cross-sectional questionnaire study using the Transgressions of Ethical Principles in Health Care Questionnaire. SETTING: A women's clinic in the south of Sweden. PARTICIPANTS: Selection criteria were: consecutive female patients coming for an outpatient appointment, ≥18-year-old, with the ability to speak and understand the Swedish language, and a known address. Questionnaires were answered by 534 women (60%) who had visited the clinic, of which 293 were included in the present study sample. PRIMARY OUTCOME MEASURE: How many times the respondent remained silent towards the healthcare system relative to the number of times the respondent spoke up. RESULTS: Associations were found between patients' silence towards the healthcare system and young age as well as lower self-rated knowledge of patient rights. Both variables showed independent effects on patients' silence in a multivariate model. No associations were found with social status, country of birth, health or other abuse. CONCLUSIONS: The results offer opportunities for designing interventions to stimulate patients to speak up and open up the clinical climate, for which the responsibility lies in the hands of staff; but more research is needed.

ABSTRACT

PURPOSE: Due to increasing cost pressure in the public health system treatments and their costs are highly relevant in the therapy for chronic diseases such as glaucoma. In the era of diagnosis-related group (DRG) reimbursement, new interventions need to prove not only their safety and effectiveness but also their cost-utility. Canaloplasty as a new interventional surgery is compared to trabeculectomy (TE) by means of a cost and effort analysis. METHODS: In this retrospective, consecutive case series patients were compared as follows: group I, 21 eyes of 21 patients undergoing canaloplasty from 2009 on and group II, 48 eyes of 42 patients, who were treated with TE with mitomycin C (MMC) from 2001 to 2004 and had intensified postoperative care. Data regarding demography, duration of hospitalisation, duration of surgery, surgical complications and interventions, and pre- and post-operative IOP were analysed within the first 6 months post operation. RESULTS: In group I mean duration of hospitalisation was 5.3 ± 0.8 days (d) and in group II 10.7 ± 2.8 d. Duration of surgery was 77 ± 14 min in group I and in group II 48 ± 11 min. On average 2.8 ± 1.0 visits were needed during follow-up in group I and 6 ± 1.5 visits in group II. The mean preoperative IOP of 28.75 ± 9.6 mmHg was lowered to 12.8 ± 3.3 mmHg after six months in group I and in group II from 34.5 ± 13.4 mmHg to 10.3 ± 4.5 mmHg. In group I, a total of 4 interventions were seen within the first six months without re-admission. In group II 107 interventions and eleven re-admissions were necessary. Mean costs for hospitalisation amount to 821.50 € in group I and 1658.50 € in group II. Overall expenses were 2379.62 € for canaloplasty and 2733.61 € for TE. CONCLUSION: Both interventions could effectively control IOP. However, trabeculectomy requires a longer hospitalisation, has higher re-admission rates and needs more frequent postoperative controls, which makes TE more costly and time-consuming than canaloplasty.

ABSTRACT

OBJECTIVE: In obstetrical and gynaecological healthcare, patients often find themselves in a vulnerable position. Sensitive issues such as sexual and reproductive health are addressed and certain procedures can be experienced as abusive. According to research a lifetime prevalence of abuse in healthcare (AHC) can be assumed for 13-28% of female patients in the Nordic countries. In the present study we analyse the content of ethical documents for healthcare professionals within obstetrics and gynaecology in Sweden, in order to find out to what extent ethical guidelines consider issues that have shown to be related to the occurrence of AHC. STUDY DESIGN: We searched the literature to find empirical data on AHC. Guidelines for nurses, midwives and physicians were selected. After developing an analytical framework based on the empirical data the content of the ethical guidelines was analysed. RESULTS: The various ethical guidelines for staff working within obstetrics and gynaecology differ distinctively from each other regarding their content of issues that are related to AHC. Issues that were mostly disregarded were: considering the patient's perspective and the patients' possible experience of violence, considering power imbalances within healthcare, sexual misconduct, how to deal with other professional's ethical misconduct and how professionals relate to each other. We found the ethical guidelines of the International Federation of Gynecology and Obstetrics (FIGO) and of the International Confederation of Midwives to be those which contained most of the issues that have empirically shown to be important in regard to AHC. CONCLUSION: While staff members from different professions may share responsibility for the same patient, their ethical guidelines vary considerably. To become a possible resource for prevention of AHC, we suggest that ethical guidelines in healthcare should be revised following empirical research on ethical conduct. As ethical guidelines cannot be effective by their existence only, we would like to initiate a discussion on the function and use of ethical guidelines in general and regarding AHC in particular. Being aware that ethical guidelines are only a part of ethics in healthcare, however, we envision a broader approach to the aim of preventing AHC, where research is encouraged on how a virtue ethics approach could be applied.

ABSTRACT

The aim of this study was to examine to what extent patients remained silent to the health care system after they experienced abusive or wrongful incidents in health care. Female patients visiting a women's clinic in Sweden (n = 530) answered the transgressions of ethical principles in Health care questionnaire (TEP), which was constructed to measure patients' abusive experiences in the form of staff's transgressions of ethical principles in health care. Of all the patients, 63.6% had, at some point, experienced staff's transgressions of ethical principles, and many perceived these events as abusive and wrongful. Of these patients, 70.3% had remained silent to the health care system about at least one transgression. This silence is a loss of essential feedback for the health care system and should not automatically be interpreted as though patients are satisfied.

ABSTRACT

BACKGROUND: Arteritis temporalis (AT) shows a variable course of the disease and may lead to transient or permanent visual loss. PATIENTS AND METHODS: In a retrospective consecutive case series 66 patients with suspected AT were followed up of which 65 underwent arterial biopsy. Symptoms, therapy and complications were followed up. RESULTS: Of the patients 32 (49.2%) revealed a positive histological finding in unilateral (55.4%) or bilateral (44.6%) biopsy. Of these 3 (9.4%) suffered a severe or fatal outcome: two with extensive ischemia of the vertebrobasilar system (one fatal) and one patient died due to acute pancreatitis, a rare side effect of systemic steroid therapy. CONCLUSION: When systemically apparent, arteritis temporalis can progress to reduction of general health, cerebral ischemia and organ infarction. Therefore, AT is a serious disease requiring interdisciplinary, immediate diagnostics and prompt therapy.

ABSTRACT

BACKGROUND: Therapeutic strategies for macular holes have been optimised during the last years. However, little is known about atypical macular holes. This study was conducted to analyse the clinical and anatomic outcome in secondary macular holes of different origins. PATIENTS AND METHODS: In a retropective analysis 60 eyes with atypical macular holes that underwent surgical repair were identified. Demografic data, lens status, macular situation, best corrected visual acuity (BCVA) pre- and postoperative and complications were documented. After exclusion of patients with trauma, vitreomacular traction syndrome and epiretinal gliosis four subgroups were analysed. Group I: after retinal detachment (n = 6), Group II: with retinal vein occlusion (n = 5), Group III: associated with diabetic macular oedema (n = 6), Group IV: during/after internal limiting membrane peeling (n = 3). RESULTS: I. Four of six eyes showed a macular hole after successful retinal detachment surgery and two eyes in the presence of retinal detachment. Five of six eyes showed postoperative closure of the macular hole. BCVA improved in four eyes, worsened in one eye and remained unchanged in one. II. In five eyes a secondary macular hole occurred after retinal vein occlusion. After vitrectomy and gas tamponade a successful hole repair was observed in all eyes. Improvement of BCVA occurred in four eyes and remained unchanged in one eye. III. In six eyes a secondary macular hole developed after rupture of cysts in diabetic macular oedema. Four of six holes were closed successfully after vitrectomy. Improvement of BCVA was seen in two eyes, impaired BCVA in one eye and in one eye vision remained unchanged. IV. This group consists of two eyes with a macular hole after vitrectomy and membrane peeling and one eye with an iatrogenic intraoperatively created macular hole. After vitrectomy and gas tamponade, anatomic success was achieved in two eyes. Improvement of BCVA was observed in two eyes, in one eye BCVA deteriorated markedly. CONCLUSIONS: In spite of the different underlying diseases and pathomechanisms, secondary macular holes can be treated successfully in the majority of cases. Visual recovery was moderate in patients with diabetic macular oedema but marked in the other subgroups. Therefore, vitrectomy seems reasonable also in non-atypical macular holes of various origins.

ABSTRACT

In evaluating ion channel function, electrophysiology, e.g., patch clamping, provides the highest information content. For the analysis of ion channel-modulating compounds, one variant of the patch-clamp technique, the whole-cell configuration, is particularly useful. We present here patch-clamp recordings in the whole-cell configuration and single channel recordings performed with planar patch-clamp chips, which are microstructured from borosilicate glass substrate. The chips are used in the Port-a-Patch, an ion channel research/screening instrument that enables automated patch-clamp experiments on a single cell. A software runs the experiment by executing user-determined protocols for cell positioning, as well as for electrical stimulation and current readout. In various electrophysiological experiments, the high quality of recordings and the versatility of the perfusion of the recorded cells are demonstrated. Quantitative pharmacological experiments are performed on sodium channels expressed in HEK cells using solution volumes in the low microliter range. The exceptionally low volume consumption in the experiments make the system attractive for work on rare or expensive compounds. Due to the low volumes necessary, a rapid solution exchange is facilitated, which is shown on RBL cells. The patch-clamp chip enables a rapid and precise perfusion, allowing sophisticated investigations on ion channel function with the Port-a-Patch.
