RESUMO
INTRODUCTION: Adverse clinical outcomes and patient dissatisfaction with care often have elements of poor communication. Factors such as illness and pharmacotherapy can affect cognition, and overestimation of patients' health literacy may contribute to suboptimal communication with patients regarding their hospitalisation and post-discharge instructions. Improved patient understanding and recall of their diagnoses and treatment is critical for adherence to treatment, follow-up and optimal clinical outcomes. The aim of the study was to assess whether a coproduced and codesigned patient-centred discharge form (PCDF) improves patients' understanding of their discharge diagnosis, in-hospital treatment and post-discharge plan. METHODS: A sample of 111 patients was enrolled through simple randomisation by admission to one of two identically operating general medicine wards. Over a 3-month period, 59 patients received the coproduced and codesigned form and 52 patients were controls. Assessment of patients' understanding of diagnosis, in-hospital management, post-discharge instructions and overall experience of care was undertaken by a blinded phone survey conducted approximately 6 days after discharge. RESULTS: Patients who received PCDF were significantly more likely to report adequate understanding of their hospital management (P < 0.001) and the post-discharge plan (P < 0.001). There was no statistically significant difference between the intervention and control groups in terms of understanding of diagnosis. Patients who received PCDF reported better understanding of care and recall of admission. CONCLUSION: The use of PCDF is associated with improved patient understanding with respect to their hospital management and post-discharge instructions. It is also associated with high levels of satisfaction as assessed by measures of patient experience.
RESUMO
The aim of this study was to determine the relationship between seminal zinc concentration and spermatozoa-zona pellucida (ZP) binding and the ZP-induced acrosome reaction (ZPIAR) in subfertile men. Semen analyses and seminal zinc concentration assessments were carried out according to the World Health Organization manual for 458 subfertile men. A spermatozoa-ZP interaction test was carried out by incubating 2 x 10(6) motile spermatozoa with a group of four unfertilized oocytes obtained from a clinical in vitro fertilization programme. After 2 h of incubation, the number of spermatozoa bound per ZP and the ZPIAR of ZP-bound spermatozoa were examined. The effect of adding 0.5 mmol L(-1) zinc to the media on the ZPIAR of spermatozoa from normozoospermic men was also tested in vitro. Seminal zinc concentration positively correlated with sperm count and duration of abstinence, but negatively correlated with semen volume. On analysis of data from all participants, both spermatozoa-ZP binding and the ZPIAR were significantly correlated with sperm motility and normal morphology, but not with seminal zinc concentration. However, in men with normozoospermic semen, the seminal zinc concentration was significantly higher in men with defective ZPIAR (< 16%) than in those with normal ZPIAR (>or= 16%) (P < 0.01). The addition of 0.5 mmol L(-1) zinc to the culture media had no effect on spermatozoa-ZP binding, but significantly reduced the ZPIAR in vitro (P < 0.001). In conclusion, seminal zinc concentration is correlated with sperm count and the duration of abstinence in subfertile men. In men with normozoospermic semen, high seminal zinc concentration may have an adverse effect on the ZPIAR.
