Preterm prelabour rupture of membranes before 23 weeks' gestation: prospective observational study.

Objective: To describe perinatal and maternal outcomes of preterm prelabour rupture of membranes (PPROM) before 23 weeks' gestation in a national cohort. Design: Prospective observational study. Setting: National population based cohort study with the UK Obstetric Surveillance System (UKOSS), a research infrastructure of all 194 obstetric units in the UK, 1 September 2019 to 28 February 2021. Participants: 326 women with singleton and 38 with multiple pregnancies with PPROM between 16+0 and 22+6 weeks+days' gestation. Main outcome measures: Perinatal outcomes of live birth, survival to discharge from hospital, and severe morbidity, defined as intraventricular haemorrhage grade 3 or 4, or requiring supplemental oxygen at 36 weeks' postmenstrual age, or both. Maternal outcomes were surgery for removal of the placenta, sepsis, admission to an intensive treatment unit, and death. Clinical data included rates of termination of pregnancy for medical reasons. Results: Perinatal outcomes were calculated with all terminations of pregnancy for medical reasons excluded, and a worst-best range was calculated assuming that all terminations for medical reasons and those with missing data would have died (minimum value) or all would be liveborn (maximum value). For singleton pregnancies, the live birth rate was 44% (98/223), range 30-62% (98/326-201/326), perinatal survival to discharge from hospital was 26% (54/207), range 17-53% (54/326-173/326), and 18% (38/207), range 12-48% (38/326-157/326) of babies survived without severe morbidity. The rate of maternal sepsis was 12% (39/326) in singleton and 29% (11/38) in multiple pregnancies (P=0.004). Surgery for removal of the placenta was needed in 20% (65/326) and 16% (6/38) of singleton and twin pregnancies, respectively. Five women became severely unwell with sepsis; two died and another three required care in the intensive treatment unit. Conclusions: In this study, 26% of women who had very early PPROM with expectant management had babies that survived to discharge from hospital. Morbidity and mortality rates were high for both mothers and neonates. Maternal sepsis is a considerable risk that needs more research. These data should be used in counselling families with PPROM before 23 weeks' gestation, and currently available guidelines should be updated accordingly.

Preterm premature rupture of the membranes (PPROM): a study of patient experiences and support needs.

BACKGROUND: Preterm prelabour rupture of membranes (PPROM) is a common obstetric condition but outcomes can vary depending on gestation. Significant maternal and foetal complications occur including preterm birth, infection, abruption, cord prolapse, pulmonary hypoplasia and even death. Although the need for psychological support is recognised it is unclear how much is actually offered to women and their families. This study aimed to survey the views of women and their families who have undergone PPROM in order to understand the care and psychological burden these families face. METHODS: An online survey was conducted, recruiting women via social media with collaboration from the patient advocacy support group Little Heartbeats. Responses were collated where fields were binary or mean and standard deviations calculated. Framework analysis was used to identify and analyse themes in free text responses. RESULTS: 180PPROM pregnancies were described from 177 respondents. Although carewas variable and respondents were from across the world there werecommon themes. Five themes were highlighted which were: a lack ofbalanced information regarding the condition, support in decisionmaking and support with the process, specific psychological supportand ongoing psychological consequences of PPROM. CONCLUSION: This survey highlights areas in which care needs to be improved for women with PPROM. Previous studies have shown that providing good care during the antenatal period reduces long-term psychological morbidity for the whole family. The need for support, with regard both to information provided to women and their families and their psychological support needs to be addressed urgently.

Googling preterm prelabour rupture of the membranes: A systematic review of patient information available on the internet.

BACKGROUND: Preterm prelabour rupture of the membranes (PPROM) complicates 3% of pregnancies and is associated with an increased risk of maternal and perinatal morbidity and mortality. In an attempt to better understand this diagnosis, patients routinely resort to the internet for medical information. The lack of governance online leaves patients at risk of relying on low-quality websites. OBJECTIVES: To assess systematically the accuracy, quality, readability and credibility of World Wide Web pages on PPROM. SEARCH STRATEGY: Five search engines (Google, AOL, Yahoo, Ask and Bing) were searched with location services and browser history disabled. Websites from the first page of all searches were included. SELECTION CRITERIA: Websites were included if they provided at least 300 words of health information aimed at patients relating to PPROM. DATA COLLECTION AND ANALYSIS: Validated assessments of health information readability, credibility and quality were undertaken, as was an accuracy assessment. Pertinent facts for accuracy assessment were based on feedback from healthcare professionals and patients through a survey. Characteristics were tabulated. MAIN RESULTS: In all, 39 websites were included, with 31 different texts. No pages were written with a reading age of 11 years or less, none were considered credible, and only three were high quality. An accuracy score of 50% or more was obtained by 45% of websites. Information that patients considered pertinent was not consistently reported. CONCLUSIONS: Search engines produce information on PPROM that is low quality, low accuracy and not credible. It is also difficult to read. This risks disempowerment. Healthcare professionals and researchers must consider how to ensure patients have access to information that they can recognise as high quality.

An analysis of general practitioners' perspectives on patient safety incidents using critical incident technique interviews.

BACKGROUND: General practitioners report difficulty in knowing how to improve patient safety. OBJECTIVES: To analyse general practitioners' perspectives of contributing factors to patient safety incidents by collecting accounts of incidents, identifying the contributory factors to these incidents, assessing the impact and likelihood of occurrence of these incidents and examining whether certain categories of contributory factors were associated with the occurrence of high-risk incidents. METHODS: Critical incident technique interviews were carried out with 30 general practitioners in Ireland about a patient safety incident they had experienced. The Yorkshire Contributory Factors Framework was used to classify the contributory factors to incidents. Seven subject matter experts rated the impact and likelihood of occurrence of each incident. RESULTS: A total of 26 interviews were analysed. Almost two-thirds of the patient safety incidents were rated as having a major-to-extreme impact on the patient, and over a third were judged as having at least a bimonthly likelihood of occurrence. The most commonly described active failures were 'Medication Error' (34.6%) and 'Diagnostic Error' (30.8%). 'Situational Domain' was identified as a contributory domain in all patient safety incidents. 'Communication' breakdown at both practice and other healthcare-provider interfaces (69.2%) was also a commonly cited contributory factor. There were no significant differences in the levels of risk associated with the contributory factors. CONCLUSIONS: Critical incident technique interviews support the identification of contributory factors to patient safety incidents. There is a need to explore the use of the resulting data for quality and safety improvement in general practice.

Safety in primary care (SAP-C): a randomised, controlled feasibility study in two different healthcare systems.

BACKGROUND: Patient safety research is conducted predominantly in hospital settings, with a dearth of insight from primary care, despite suggestions that 2.2% of primary care consultations result in a patient safety incident. This study aimed to assess the feasibility of an intervention intended to improve patient safety in general practice. METHODS: A randomised controlled feasibility study was conducted with general practices in the Republic of Ireland (N = 9) and Northern Ireland (N = 2), randomly assigned to the intervention (N = 5) or control (N = 6) group. The nine-month intervention consisted of: 1) repeated safety climate (SC) measurement (using GP-SafeQuest questionnaire) and feedback (comparative anonymised practice-level SC data), and 2) patient record reviews using a specialised trigger tool to identify instances of undetected patient harm. For control practices, SC was measured at baseline and study end only. The intervention's perceived usefulness and feasibility were explored via an end-of-study questionnaire and semi-structured interviews. RESULTS: Thirteen practices were invited; 11 participated; 10 completed the study. At baseline, 84.8% of intervention practice staff (39/46) and 77.8% (42/54) of control practice staff completed the SC questionnaire; at the study terminus, 78.3% (36/46) of intervention practice staff and 68.5% (37/54) of control practice staff did so. Changes in SC scores, indicating improvement, were observed among the intervention practices but not in the control group. The trigger tool was applied to 188 patient records; patient safety incidents of varying severity were detected in 19.1% (36/188). Overall, 59% of intervention practice team members completed the end-of-study questionnaire, with the majority in both healthcare systems responding positively about the intervention. Interviews (N = 9) identified the intervention's usefulness in informing practice management and patient safety issues, time as a barrier to its use, and the value of group discussion of feedback. CONCLUSION: This feasibility study suggests that a definitive randomised controlled trial of the intervention is warranted. Our findings suggest that the intervention is feasible, useful, and sustainable. Practices were willing to be recruited into the study, response and retention rates were acceptable, and there is possible evidence of a positive effect of the intervention. TRIAL REGISTRATION: The trial registration number is: ISRCTN11426121 (retrospectively registered 12th June 2018).

Perceived safety climate in Irish primary care settings-a comparison with Scotland and England.

BACKGROUND: Safety climate (SC) measurement is a key component of quality and safety initiatives in primary healthcare. OBJECTIVES: To (1) measure perceived SC in Irish primary care; (2) examine whether perceptions of safety varied according to respondent characteristics; and (3) compare responses from our Irish sample to data from England and Scotland. METHODS: PC-SafeQuest Survey was administered to all practice staff in Irish general practices between March and May 2016. This survey consists of 30 items across five safety domains (workload, communication, leadership, teamwork, and safety systems). Multiple regression analysis was used to identify predictor variables of perceived safety. The effect size of the difference between the Irish sample's scores and published English and Scottish data were calculated. RESULTS: A total of 231 questionnaires (38.5%) were returned. Generally, positive perceptions of perceived safety were identified among Irish respondents, but workload had the lowest overall mean score (M = 4.3, SD = 1.2) of the five domains. Comparisons across the Irish, English and Scottish samples identified a medium size effect difference in workload; Scottish respondents perceived workload to have less of a negative impact on safety than Irish or English counterparts (Cohen's d = 0.602, 0.67 respectively). Analyses indicated that Irish GP principals perceived a more negative impact of workload on safety than administrative staff (ß = 0.28, P = 0.03). CONCLUSION: Irish SC data are largely similar to those of England and Scotland. The perceived potential for workload to negatively impact upon safety emerged within each country. In Ireland, GP principals perceive this as a greater threat than practice administrators do.

Potential value of patient record review to assess and improve patient safety in general practice: A systematic review.

BACKGROUND: There is limited research, and guidance, on how to address safety in general practice proactively. OBJECTIVES: This review aimed to synthesize the literature describing the use of patient record review (PRR) to measure and improve patient safety in primary care. The PRR methodologies utilized and the resulting outcomes were examined. METHODS: Searches were conducted using Medline, Embase, CINAHL and PsycINFO in February 2017. Reference lists of included studies and existing review papers were also screened. English language, peer-reviewed studies that utilized PRR to identify patient safety incidents (PSIs) occurring in general practice were included. Two researchers independently extracted data from articles and applied the Quality Assessment Tool for Studies with Diverse Designs. RESULTS: A total of 3265 studies were screened, with 15 included. Trigger tools were the most frequent method used for the PRRs (n = 6). The mean number of safety incidents per 100 records was 12.6. Within studies, a mean of 30.6% of incidents were associated with severe harm (range 8.6-50%), and a mean of 55.6% of incidents was considered preventable (range 32.7-93.5%). The most commonly identified types of PSIs related to medication and prescribing, diagnosis, communication and treatment. Three studies reported on improvement actions taken after the PRRs. CONCLUSION: This review suggests that PRR may be a promising means of proactively identifying patient safety incidents and informing improvements.

A Systematic Review of Primary Care Safety Climate Survey Instruments: Their Origins, Psychometric Properties, Quality, and Usage.

IMPORTANCE: Safety climate (SC) measurement is a common and feasible method of proactive safety assessment in primary care. However, there is no consensus on which instrument is "best" to use. OBJECTIVE: The aim of the study was to identify the origins, psychometric properties, quality, and SC domains measured by survey instruments used to assess SC in primary care settings. DATA SOURCES: Systematic searches were conducted using Medline, Embase, CINAHL, and PsycInfo in February 2016. STUDY SELECTION: English-language, peer-reviewed studies that reported the development and/or use of a SC survey in a primary care setting were included. DATA EXTRACTION AND SYNTHESIS: Two reviewers independently extracted data (survey characteristics, origins, and psychometric properties) from studies and applied the Quality Assessment Tool for Studies with Diverse Designs to assess methodological rigour. Safety climate domains within surveys were deductively analyzed and categorized into common healthcare SC themes. RESULTS: Seventeen SC surveys were identified, of which 16 had been adapted from 2 main U.S. hospital-based surveys. Only 1 survey was developed de novo for a primary care setting. The quantity and quality of psychometric testing varied considerably across the surveys. Management commitment to safety was the most frequently measured SC theme (87.5%). Workload was infrequently measured (25%). CONCLUSIONS AND RELEVANCE: Valid and reliable instruments, which are context specific to the healthcare environment for intentional use, are essential to accurately assess SC. Key recommendations include further establishing the construct and criterion-related validity of existing instruments as opposed to developing additional surveys.

Cholesteryl to improve the cellular uptake of polymersomes within HeLa cells.

The need to develop a greater understanding of drug delivery systems has arisen through the development of alternative biological based therapeutics. Drug delivery systems need to adapt and respond to this increasing demand for cellular transportation of highly charged species. Polymersomal drug delivery systems have displayed great potential and versatility for such a task. In this manuscript we present the synthesis, characterisation and biological evaluation of six amphiphilic random co polymers with varying amounts of cholesteryl (0-39%wt) before the subsequent formation into polymersomes. The polymersomes were then analysed for size, zeta potential, encapsulation efficiency, release kinetics and cellular uptake. Results confirmed that the polymersome containing 12%wt cholesteryl polymer displayed a ten-fold increase in cellular uptake of Fitc-CM-dextran when compared to un-encapsulated drug, crossing the cellular membrane via endocytosis. The size of these vehicles ranged between 100 and 500nm, zeta potential was shown to be neutral at -0.82mV ±0.2 with encapsulation efficiencies in the region of 60%. The ease of adaptability and preparation of such systems renders them a viable alternative to liposomal drug delivery systems.
