Adverse Events in Competitive Freediving – Clinical Presentation, Management, and Prevention

Freediving (synonyms: breath-hold diving, apnea diving) has become a popular leisure activity and continues to gain popularity and recognition as both a competitive and recreational sport. Formal freediving competitions are sanctioned by the international Confédération Mondiale des Activités Subaquatiques (CMAS) or the Association Internationale pour le Développement de l’Apnée (AIDA). Both organizations have set up rules and guidelines for competitive pool disciplines where athletes compete for maximum submerged breath-hold time or underwater swimming distance with or without fins. In freshwater disciplines athletes strive for maximum depth using different freediving techniques. These aquatic breath-holding activities carry unique medical risks that are related to environmental factors eliciting extreme physiological challenges. Pool disciplines carry an increased risk of hypoxemia and, consequently, loss of consciousness, particularly in untrained individuals. Hypoxic complications are reported to occur in up to 10% of dives during freediving competitions. Shallow water blackout following hyperventilation to extend breath-hold capability is a serious risk applying to all aquatic breath-hold activities, however, is more common during recreational freediving. Deep freediving poses the athlete to further risks such as barotrauma of ear drums or lungs, immersion pulmonary edema, nitrogen narcosis, and decompression sickness when reaching great depths. While serious complications in competitive freediving are rare, however, the risk clearly rises with increasing depth. Special breathing techniques to increase lung volumes such as glossopharyngeal insufflation carry additional risks. This article reviews possible complications and injury that may occur in competitive freedivers and discusses strategies for management and prevention of possible injury.

Colonization of Bone Flaps by Cutibacterium acnes During Decompressive Craniectomies for Traumatic and Non-traumatic Indications: A Retrospective Observational Study.

Background Cutibacterium acnes (C. acnes) is one of the most common bacteria in the human skin microbiota. Due to it generally requiring special culturing techniques, it was generally not routinely included in culture. However, recent laboratory automation advancements have allowed C. acnes to be a routinely tested pathogen. Though this could improve outcomes by detecting a virulent pathogen early, it has raised concerns about potential false positives leading to increased costs and medical risks. This study aims to analyze the C. acnes colonization rates in traumatic craniectomies and compare it to non-traumatic craniectomies, the former including risk factors due to penetrations and the latter being conceptually similar to a craniotomy with a lack thereof. This would help establish a baseline rate to understand the pathogen's implications better. Methodology We analyzed the electronic health records of 124 patients who underwent a craniectomy followed by a cranioplasty at Inova Health System from January 1, 2018, to January 1, 2023. The following categories of data were recorded for each patient: patient descriptors, comprehensive surgical timelines and outcomes, and bone flap viability and microbial colonization assessment. The chi-squared tests of independence and Wilcoxon signed-rank tests were used to assess statistical significance between groups in the indications underlying surgery (traumatic vs. non-traumatic) with C. acnes colonization, flap status (reimplanted vs. discarded), hospital length of stay (LOS), and unexpected 30-day readmission. Results Traumatic (67%) and non-traumatic (33%) craniectomies were compared. There was no significant association between the two craniectomy etiologies in terms of C. acnes colonization (40% vs. 26.5%, p=0.19), flap discardment (40% vs. 24%, p=0.12), or readmission rates (20% vs. 9.6%, p=0.18). However, a significant association was found between C. acnes colonization and LOS during the index craniectomy procedure (24.8 vs. 25.9 days, p=0.049), indicating that colonization may influence LOS. No significant association was found between the type of cranial surgery and LOS (p=0.83), suggesting other factors may play a more crucial role in determining LOS. The findings highlight the need to consider the impact of C. acnes colonization on surgical outcomes and hospital protocols. Conclusion Our findings illustrate that there is no significant difference between C. acnes colonization in traumatic and non-traumatic craniectomies; therefore, C. acnes can be expected to be cultured at a baseline level regardless of the etiology. Furthermore, there was no association with surgical indication and flap status, LOS, and readmission rates. However, a significant association was found between C. acnes status and LOS, indicating the increased complexity of care associated with the pathogen's detection. These findings support the protocol of deferring C. acnes culturing unless specific concerns are found.

Overview of Finnish national patient data repository for research on medical risk assessment

The Kanta Patient Data Repository (PDR) contains healthcare data from the population of Finland for more than a decade. The repository is a continuously expanding real world dataset produced by many information systems and healthcare service providers. Kanta data has been available for secondary uses such as scientific research since 2019. The data can be requested from the Finnish authority Findata. However, before a request has been accepted, it is difficult to assess if the accumulated data allows answering a specific research question. Publicly available descriptions of data structures in the Kanta PDR do not tell how much they are used in practice. This publication enables future data use cases by providing a view on the overall availability of types of structured health data in the Kanta PDR based on a sample of 96 200 medical histories of over 18-year-old patients. We conclude that the Kanta PDR is a promising source of real world data for development and evaluation of medical risk calculators within the Finnish population. The wide coverage of the Finnish population and timeliness of the data are its strengths as a source of research data also outside of Finnish context. However, the limitations on data availability in variable level need to be considered on a case-by-case basis. Main challenges in the use of data in the Kanta PDR are multiple code systems for laboratory results, short durations of recorded data for specific data types, and missing or very rarely used structured format e.g., in cases of tobacco and alcohol use.

What patients with kidney stones believe about their condition.

Patients' beliefs about their illness are of central importance in understanding how a person adjusts to their condition and adheres to self-management recommendations. No previous studies have set out to quantitatively examine Illness beliefs in patients with kidney stones (KS). 112 patients with radiological confirmation of KS (59% male, mean (x̄) age = 50.1 years [sd14.15 years], 50.5% previous surgical treatment) attending for clinical consultation completed the Brief-Illness Perception Questionnaire alongside a range of demographic and illness related variables. Template analysis was undertaken on the free text responses of patients' beliefs about what had caused their KS. Almost a third (31.2%) of patients did not know what had caused their KS. Of those who cited a cause, dietary factors, fluid intake, medical risk factors (e.g. Inflammatory bowel disease), genetics, and psychological factors were ranked as the most important. Patients generally believed they had a reasonable understanding of KS (x̄=6.32 [sd3.21]), but reported poor levels of personal control over their KS (x̄=2.90 [sd2.93]) and high confidence in the effectiveness of treatments (x̄=8.64 [sd1.90]). Patients with a recurrence believed KS had a significantly greater impact on their life (z=-2.56, p = 0.01) and had greater emotional consequences (z=-2.77, p < 0.01). Perceptions of poor personal control over KS and a strong belief in medical/surgical treatment was evident regardless of first or recurrent stone, gender, age, previous surgical management of KS or time since diagnosis. Results highlight the need to actively increase patients' perceptions of personal control in the management and prevention of KS.

Enabling Emergency Department Staff to Support Domestic Violence Victims of Strangulation

ABSTRACT The study reported here investigated what enables emergency department (ED) staff to support domestic violence victim-survivors of strangulation, which poses potentially life-threatening medical and psychosocial risks. Informed by Appreciative Inquiry, interviews were conducted with twelve staff from eight emergency departments in New South Wales, Australia. Doctors, nurses, and social workers with experience in supporting victim-survivors of domestic violence-related strangulation were interviewed. De-identified transcripts were analysed using inductive thematic analysis. Themes identified from the data were the importance of recognising strangulation injuries, that understanding experiences of violence improves ED staff’s responses to victim-survivors of strangulation, the value of social work in multidisciplinary response, and that informal support sustains staff in this work. These themes highlight the need for emergency department staff education in identifying and responding to domestic violence and strangulation, which enables informed responses, positive patient engagement, and effective multidisciplinary care. IMPLICATIONS Multidisciplinary care for health and safety assessments are essential for domestic violence victim-survivors of strangulation presenting to emergency departments. 24-hour access to social workers in emergency departments facilitates safety planning and may mitigate the risks of escalating violence. Strangulation and domestic violence education is essential for emergency department staff. There is an evident need for increased social work roles in EDs, especially in rural hospitals, to support victim-survivors and to apply a social work approach to train ED staff to respond appropriately. Formalising supportive structures through enhancing social work and domestic violence education in emergency departments whilst encouraging informal support networks for staff may enhance safety for victims-survivors and maximise staff emotional wellbeing.

Psychiatric outcomes among COVID-19 egyptian patients at ain shams university quarantine hospitals: A cross-sectional study

BackgroundPsychological repercussions resulting from coronavirus disease 2019 (COVID-19) have been encountered, such as anxiety, depression, insomnia, and post-traumatic stress disorder (PTSD). The study aimed to assess the frequency and severity of PTSD, depression, and anxiety in a sample of Egyptian patients with COVID-19 infection and analyze potential risk factors. The current study is a descriptive cross-sectional, hospital-based study, conducted from August 2020 to June 2021. The sample was selected from patients diagnosed with COVID-19 infection at Ain Shams University hospitals (outpatient clinics and inpatient units). Patients underwent a COVID severity criteria scoring system, structured clinical interview for DSM-IV (SCID-I), PTSD checklist–Civilian Version (PCLC), Beck depression inventory, and Taylor’s manifest anxiety scale.ResultsPTSD was observed in 79.29% of the study sample, 61.43% had depression, and 18.57% had anxiety. The severity of COVID-19 infection was significantly associated with PTSD severity mean scores (P value = 0.027). Furthermore, a significant relationship was observed between the severity of depression and COVID-19 infection severity (P value = 0.028). The number of comorbid medical risk factors demonstrated significance to PTSD severity (P value = 0.014).ConclusionA significant portion of the study’s patients experienced psychiatric consequences following COVID-19 infection, with 79.29% developing PTSD, 61.43% suffering from depression, and 18.57% experiencing anxiety. Various factors, such as the presence of chronic medical illnesses and the number of co-morbid medical risk factors, were observed to contribute to these psychiatric outcomes. Therefore, comprehensive psychiatric assessment and management in COVID-19 patients especially with severe forms of the disease and hospitalized patients are mandatory.

Study protocol of a breathing and relaxation intervention included in antenatal education: A randomised controlled trial (BreLax study).

Antenatal education is part of antenatal care in many countries. Physical and mental preparation for childbirth and information on pain management are considered key elements of antenatal education classes. Evidence suggests that women who participate in antenatal education classes appear to benefit in terms of self-efficacy and childbirth experience. In particular, women with increased fear of childbirth benefit from trained breathing and relaxation techniques in antenatal education. However, little is known about the effect of breathing and relaxation techniques on the outcomes of healthy pregnant women without fear of childbirth or who do not have medical or obstetric risks, or on neonatal outcomes. The aim of this study is to test whether including a breathing and relaxation technique in an antenatal education class will improve self-efficacy towards birth compared to a standard antenatal education class. The study will be a two-armed randomised controlled trial (RCT). Healthy pregnant women between the 12th and 30th week of gestation with singleton low-risk pregnancies and who are receiving routine antenatal care will be recruited in a hospital in Switzerland. All women included will attend an 8-hour antenatal education class. The intervention group will additionally practise a breathing and relaxation technique, receive a handbook to guide their exercise practice at home, and be provided with access to an online brochure with video and audio recordings for guidance. Data on maternal and neonatal outcomes will be collected after recruitment, in the 37th week of pregnancy, and two to four weeks postpartum. The effectiveness of including a breathing and relaxation technique in antenatal education classes on women's self-efficacy is discussed as a means to improving women's pregnancy and childbirth outcomes.

Risk Retention and Management Implications of Medical Malpractice in the Italian Health Service

This work provides an economic exploration of the multifaceted world of medical malpractice risk. Third party liability insurance plays a central role in protecting healthcare providers and public care institutions from the financial consequences of medical malpractice claims, although in recent years, the industry landscape has been characterised by periods of distress for this type of protection, with rising litigations and reimbursement costs, resulting in a peculiarly complex market. For the Italian context, the study focuses on the financial repercussions for healthcare institutions of the growing trend towards risk retention practises, legally empowered by the introduction of Law No. 24/2017. The analysis employs Generalised Linear Models for the regressive approach to incorporate the structural and organisational characteristics of hospitals and uses quantitative simulations to explore different scenarios at a regional aggregate level. Due to the limited existing literature and data on the topic, this research aims to provide new methods for effectively understanding and managing this type of risk, thereby supporting decision-making processes in the healthcare sector.

Abortion.

Induced abortion is safe, is common, and reduces pregnancy-related maternal morbidity and mortality. Internal medicine physicians are uniquely positioned to counsel patients on their pregnancy options, assess medical risks of pregnancy in the context of comorbidities, refer for abortion care when the patient desires it, or provide abortion care themselves. Clinicians can also provide anticipatory guidance about what patients should expect if they seek abortion care.

Maternal Medication Use in Pregnancy: A Narrative Review on Assessing and Communicating the “Risk” of Birth Defects to the Patient

The state of knowledge regarding the teratogenic effects of maternal use of medications during pregnancy is constantly evolving and is often uncertain. Timely access to high-quality information may reduce prolonged harmful exposures, decrease the number of preventable birth defects, empower patients with accurate information about the risks of exposure, and prevent unnecessary patient anxiety and pregnancy termination. In this narrative review, we describe the process by which the teratogenic risk of medications is assessed by experts in medicine, genetics, and epidemiology and how identifiable risks can be effectively communicated to patients. Risk assessment of birth defects in human pregnancy involves collecting and synthesizing available data through a proper and rule-driven evaluation of scientific literature. Expert consensus is a practical approach to determine whether a given exposure produces damage after careful consideration of gestational timing, dose and route of the exposure, maternal and fetal genetic susceptibility, as well as evidence for biological plausibility. The provision of teratogen risk counseling through appropriate interpretation of information and effective knowledge translation to the patient is critical for the prevention of birth defects and maximizing healthy pregnancies.

Prevalence of visual abnormalities detected through paediatric vision screening in Queensland, Australia.

Vision screening programs can provide epidemiological information regarding visual impairment in children. This study aims to report the characteristics of visual abnormalities diagnosed through the Primary School Nurse Health Readiness Program (PSNHRP) in Queensland, Australia. A retrospective review of vision screening records from the PSNHRP between January 2017 and December 2020 was undertaken. Children aged between 4 and 7 who underwent vision screening were included for review. Children with a visual acuity of worse than 6/9-1 using the Parr 4 m letter-matching chart or those who failed the SPOT Vision Screener were referred to an optometrist or ophthalmologist for review. 164 890 children underwent vision screening. 12148 children failed visual screening (7.4%) and were referred for an eye assessment. 6011 (69.4%) of the 8659 children who attended ophthalmic review had a confirmed visual abnormality. Of 164 890 screened children, 1187 (0.72%) were confirmed to have anisometropia, 3843 (2.33%) had refractive error, 194 (0.12%) had strabismus, 755 (0.46%) had anisometropic amblyopia, 136 (0.08%) had strabismic amblyopia, and 1356 (0.82%) had an unspecific abnormality. There was no statistically significant difference in the age at screening between any visual abnormality (p = 0.94). Anisometropia, refractive error, and strabismus were significantly more common in females than males (p = 0.03, p < 0.01, and p = 0.03 respectively), whereas anisometropic amblyopia was more common in males (p < 0.01). We report the prevalence of visual abnormalities detected through the PSNHRP vision screening program. Identification of medical or socioeconomic risk factors that are likely to be associated with visual abnormalities can help to optimise vision screening programs.

Space Radiology: Emerging Nonsonographic Medical Imaging Techniques and the Potential Applications for Human Spaceflight.

Space medicine is a multidisciplinary field that requires the integration of medical imaging techniques and expertise in diagnosing and treating a wide range of acute and chronic conditions to maintain astronaut health. Medical imaging within this domain has been viewed historically through the lens of inflight point-of-care ultrasound and predominantly research uses of cross-sectional imaging before and after flight. However, space radiology, a subfield defined here as the applications of imaging before, during, and after spaceflight, will grow to necessitate the involvement of more advanced imaging techniques and subspecialist expertise as missions increase in length and complexity. While the performance of imaging in spaceflight is limited by equipment mass and volume, power supply, radiation exposure, communication delays, and personnel training, recent developments in nonsonographic modalities have opened the door to their potential for in-mission use. Additionally, improved exam protocols and scanner technology in combination with artificial intelligence algorithms have greatly advanced the utility of possible pre- and postflight studies. This article reviews the past and present of space radiology and discusses possible use cases, knowledge gaps, and future research directions for radiography, fluoroscopy, computed tomography, and magnetic resonance imaging within space medicine, including both the performance of new exam types for new indications and the increased extraction of information from exams already routinely obtained. Through thoughtfully augmenting the use of these tools, medical mission risk may be reduced substantially through preflight screening, inflight diagnosis and management, and inflight and postflight surveillance.

Comparing Glucagon-like peptide-1 receptor agonists versus metformin in drug-naive patients: A nationwide cohort study.

Glucagon-like peptide-1 receptor agonists (GLP-1 RA) are increasingly being prescribed in drug-naive patients. We aimed to contrast add-on therapy, adherence, and changes in biomarkers, 1 year after treatment initiation with GLP-1 RA or metformin. Using Danish nationwide registers, we included incident GLP-1 RA or metformin users from 2018 to 2021 with glycated hemoglobin (HbA1c) ≥ 42 mmol/mol. GLP-1 RA initiators were matched to metformin initiators in a ratio of 1:1 to assess outcomes in prediabetes and diabetes. Main outcomes analyzed were 1-year risk of add-on glucose-lowering medication and 1-year risk of nonadherence. One-year risks were estimated with multiple logistic regression and standardized. Multiple linear regression was used to estimate the average differences in biomarker changes. In total, 1778 individuals initiating GLP-1 RA and metformin were included. After standardizing for various factors, GLP-1 RA compared with metformin was associated with reduced 1-year risk of add-on glucose-lowering treatment in patients with prediabetes (1-year risk ratio [RR]: 0.27, 95% confidence interval [CI]: 0.10-0.44) and diabetes (RR: 0.67, 95% CI: 0.37-0.98). GLP-1 RA was associated with higher 1-year risk of nonadherence among patients with prediabetes (RR: 1.60, 95% CI: 1.45-1.75), but no difference in patients with diabetes (RR: 0.88, 95% CI: 0.70-1.06). Compared to metformin, GLP-1 RA was associated with greater HbA1c reduction (prediabetes: -2.59 mmol/mol 95% CI: -3.10 to -2.09, diabetes: -3.79 mmol/mol, 95% CI: -5.28 to -2.30). GLP-1 RA was associated with a reduced risk of additional glucose-lowering medication, achieving better glycated hemoglobin control overall. However, among patients with prediabetes, metformin was associated with better adherence.

Integrated health and social care for pregnant women and young families in a vulnerable situation in the Netherlands: Professionals’ views on cross-sectoral collaboration

PurposeThis qualitative study investigated the perspective of professionals from the medical, social, and public health care sectors with regard to: cross-sectoral collaboration in providing integrated health and social care during the first thousand days of life (preconception up to children aged two years) for pregnant women and young families in a vulnerable situation. This knowledge is needed for the enhancement of cross-sectoral collaboration and the implementation of integrated care. MethodsProfessionals (n = 35) were recruited from three deprived municipalities in South-Limburg, the Netherlands. Semi-structured interviews gained insight into professionals’ views, by using a theoretical framework based on the ‘National model for integrated care for childhood overweight and obesity’. ResultsProfessionals stressed the importance of addressing both medical and social risk factors in pregnant women and young families in a vulnerable situation. However, their interpretation of vulnerability differed, hindering collaborative working. Furthermore, cross-sectoral collaboration was restricted by lack of formal cooperation agreements between sectors, and unclear referral lines from the medical to the social sector. Professionals often did not know the expertise and role of other sectors. Digital information and referral systems are not connected between the sectors which acts as an inhibiting factor. Discussion/ConclusionThis study highlights the need and ways to facilitate collaborative working between the medical, social, and public health care sectors in delivering integrated care. Recommendations include: 1) Enforcing implementation strategies aimed at facilitating collaborative working: formal regulations, structured agreements, and use of consistent definitions and protocols to facilitate integration. 2) Strengthen informal connections between professionals by the Solid Start local coalitions. 3) Align all professionals, also those not directly involved in the Solid Start local coalition, with the goals and vision of the coalition. 4) Implement a joint digital file or IT referral system to improve cross-sectoral collaboration. 5) Enhance collaboration between sectors at case level through multidisciplinary consultation.

Measurement of Radiation Doses in Computed Tomography and Estimated Radiological Risk factor of Cancer - Libya

The aim of this study is to evaluate the radiation doses received by adult patients undergoing six common routine types of CT scans in Libya. These types cover the Head, Neck, Chest, Abdomen, Pelvis and Trunk. This work consists of measurements of (191) patients examinations in (1) government Hospital. The average doses area CTDIvol Volume computed tomography dose index (CTDIvol ) and dose-length product (DLP) were measured for each patient for each examination. The corresponding average effective doses were calculated from the DLP measurement for each scan using NRPP X-Dose software online. The risk rate of developing cancerous tumors as a results of exposure to radiation doses during diagnostic medical applications was also measured using a CT scanner, and the results were compared with these derived from similar surveys published by the United Nations Scientific Committee on the effects of Atomic Radiation (UNSCEAR, 2000,2007). Current measurements will provide a useful starting point and baseline for setting National diagnostic reference levels for the first time. These results can be used in the future to evaluate the populations collective dose of medical exposure and risk of cancer from CT Scan applications.

Multitasking during Medication Management in a Nursing Home: A Time Motion Study.

Multitasking, defined as performing two or more interventions simultaneously, increases the cognitive burden of clinicians. This may, in turn, lead to higher risk of medication and procedural errors. Time motion study (TMS) data for nurses in nursing homes revealed an extensive amount of multitasking while managing medications. Further investigation of multitasked nursing interventions will provide a foundation for optimizing medication management workflows. Using a continuous observational TMS method, this study aimed to describe pairs of multitasked nursing interventions associated with medication management interventions, including preparing and administering medications, assessing medication effects, instructing on medications, and documenting medication administration. An external nurse observer used 57 predefined Omaha System nursing interventions embedded within TimeCaT (version 3.9), TMS data recording software to collect observation data in a single nursing home. A total of 120 hours of time-stamped observation data from nine nurses were downloaded from TimeCaT and analyzed using descriptive and inferential statistics. The majority (74%) of medication management interventions were multitasked, resulting in 2,003 pairs of multitasked interventions. Of the 57 Omaha System nursing interventions, 35 were involved in these multitasking pairs. When nurses multitasked, the average duration of medication preparation was longer (non-multitasked: 81 seconds; multitasked: 162 seconds, p < 0.05), while the average duration of medication administration record documentation was shorter (non-multitasked: 93 seconds; multitasked: 66 seconds, p < 0.05). The findings reveal the complexity of medication management in nursing homes with numerous and diverse multitasking pairs. Findings provide a platform for in-depth study of medication management multitasking in the clinical context, and inform future efforts to create clinical and informatics solutions to optimize medication management workflow. This method may be also applied to examine medication management and multitasking in other clinical settings.

Socioeconomic and medical determinants of state-level subjective cognitive decline in the United States.

It is important to understand the socioeconomic and medical determinants of subjective cognitive decline (SCD) at a population level in the United States. The primary outcomes are state-level rates of SCD and SCD-related functional impairment in adults aged ≥ 45, both measured in the Behavioral Risk Factor Surveillance System from 2016 to 2022. The exposures are state-level rates of poverty, unemployment, homelessness, college education, racial and ethnic minorities, uninsurance, smoking, hypertension, diabetes, and obesity as well as household income and physician density. The strongest state-level associations with rates of SCD were the prevalence of diabetes (rho=0.64), hypertension (rho=0.59), and poverty (rho=0.58; all p<0.001), and with SCD-related functional impairment were prevalence of poverty (rho=0.71), diabetes (rho=0.68), and hypertension (rho=0.53; all p<0.001). This study highlights critical links between SCD and socioeconomic and medical determinants in adults aged ≥ 45 in the United States, including the prevalence of poverty, diabetes, and hypertension. State-level analysis reveals socioeconomic and medical risk factors for subjective cognitive decline (SCD) at a population level. The prevalence of poverty is a critical contributor to the state-level prevalence of SCD. The prevalence of diabetes and hypertension are also strong state-level determinants of SCD. Addressing the burden of cognitive decline at the population level necessitates targeting socioeconomic and medical factors.

Impact of vaginism on mode of delivery and obstetrical outcomes

IntroductionAccording to ICD 10, vaginism is defined as the presence of spasm of the pelvic floor muscles surrounding the vagina, causing occlusion of the vaginal opening. Intromission is impossible or painful. Vaginism, whose prevalence is estimated at 1%, is often diagnosed during pregnancy follow-up, when clinical examination is difficult or impossible. However, few studies report obstetrical complications and pregnancy outcomes associated with this pathology. ObjectiveEvaluate the impact of vaginism on mode of delivery and obstetrical complications. Materials and methodsComparative, monocentric, retrospective study at the Montreuil maternity hospital between January 2019 and January 2024 that included all singleton deliveries in cephalic presentation at term. Vaginism was defined as an involuntary contraction of the pelvic muscles that made clinical examination during pregnancy impossible. Mode of delivery (caesarean section during labour, operative delivery, spontaneous vaginal delivery) and obstetric complications (episiotomy, OASIS, complex tear, Postpartum haemorrhage (PPH) due to tear) were compared between patients with vaginism and a control group, in univariate analysis and multivariate logistic regression with adjustment for maternal age, BMI, maternal origin, gestational age, high obstetrical and medical risk level, diabetes with or without insulin use, pregnancy complications, Robson group and birthweight. A propensity score adjustment with matching 1 case to 3 controls was conducted. ResultsDuring the study period, 13,469 patients were included, among which 440 patients had vaginism. In univariate analysis, patients with vaginism had a higher rate of caesarean section (16,8% versus 9,4%, p < 0.001), operative delivery (29,3% versus 13,3%, p < 0.001), episiotomy (12,5% versus 5.3 %, p < 0.001), OASIS (3.4 % versus 1.0 %, p < 0.001), complex tear (17,5% versus 7,7%) and PPH due to tear (2,5% versus 1,1%, p = 0,009).After adjustment, vaginism appeared to be an independant risk factor for cesarean section with a psaOR of 1.38 [1.02–1.85], operative delivery psaOR 2.39 [1.83–3,10], OASIS psaOR 2,19 [1.10–4,27], and complex tear psaOR 1,39 [1,02–1,87] ConclusionVaginism appears to be an independent risk factor for cesarean section, operative delivery, OASIS, and complex tear. Further studies should evaluate the impact of early and appropriate follow-up during pregnancy on adverse obstetrical outcomes.
