Trends, safety, and efficacy of wearable male sexual devices.

INTRODUCTION: The prevalence of male sexual dysfunction (MSD) increases with age, with >50% of men aged >40 years reporting erectile dysfunction (ED). In recent years, wearable male sex devices (WMSDs) have been increasingly utilized by patients and recommended by sexual medicine clinicians. OBJECTIVES: This study seeks to investigate the safety and efficacy of products currently marketed for the treatment of MSD. METHODS: Available products for WMSDs were reviewed by analyzing product websites, forums, advertisements, and clinical recommendations. Qualitative comparisons were based on patient reviews, cost, and specific features. Investigatory evidence and Food and Drug Administration status were also reviewed. Additionally, Google Trends was used to determine the popularity of devices over time. RESULTS: Eight WMSDs for the treatment of MSD and enhancement of sexual pleasure were reviewed. Constriction bands, such as the Maintain Ring Loop, Eddie by Giddy, and Xialla, have shown significant benefits in clinical trials and were the most popular devices among patients. Smart devices can provide real-time feedback on erectile quality and/or sexual performance. Similar to the RigiScan, the Adam sensor provides feedback on erectile quality while monitoring changes in penile tumescence during sleep with additional analysis available through a mobile application. Neuromodulation devices such as the Morari Patch and vPatch/in2 Patch use electrical stimulation to delay ejaculation and improve sexual function. The FirmTech Performance Ring uses sensors to track the vital signs of erectile fitness with clinical trials ongoing. CONCLUSIONS: Overall, this review describes the available investigatory evidence for a range of WMSDs and highlights the potential benefits and limitations of these devices in treating MSD and enhancing sexual pleasure. Further research is needed to evaluate the effectiveness of these devices and to determine which ones may be the most suitable for individual patients.

Polygenic Scores Clarify the Relationship Between Mental Health and Gender Diversity.

Background: Gender-diverse individuals are at increased risk for mental health problems, but it is unclear whether this is due to shared environmental or genetic factors. Methods: In two SPARK samples, we tested for associations of 16 polygenic scores (PGSs) with quantitative measures of gender diversity and mental health. In study 1, 639 independent adults (59% autistic) reported their mental health with the Adult Self-Report and their gender diversity with the Gender Self-Report (GSR). The GSR has 2 dimensions: binary (degree of identification with the gender opposite that implied by sex designated at birth) and nonbinary (degree of identification with a gender that is neither male nor female). In study 2 (N = 5165), we used a categorical measure of gender identity. Results: In study 1, neuropsychiatric PGSs were positively associated with Adult Self-Report scores: externalizing was positively associated with the attention-deficit/hyperactivity disorder PGS (ß = 0.10 [0.03-0.17]), and internalizing was positively associated with the PGSs for depression (ß = 0.07 [0-0.14]) and neuroticism (ß = 0.10 [0.03-0.17]). Interestingly, GSR scores were not significantly associated with any neuropsychiatric PGS. However, GSR nonbinary was positively associated with the cognitive performance PGS (ß = 0.11 [0.05-0.18]), with the effect size comparable in magnitude to the associations of the neuropsychiatric PGSs with the Adult Self-Report. Additionally, GSR binary was positively associated with the nonheterosexual sexual behavior PGS (ß = 0.07 [0-0.14]). In study 2, the cognitive performance PGS effect replicated; transgender and nonbinary individuals had higher PGSs (t316 = 4.16). Conclusions: We showed that while gender diversity is phenotypically positively associated with mental health problems, the strongest PGS associations with gender diversity were with the cognitive performance PGS, not the neuropsychiatric PGSs.

This research explores the connection between gender diversity, mental health, and genetic factors. It reveals that gender-diverse individuals often experience more mental health issues. Interestingly, rather than finding evidence linking these mental health challenges to genetic risk factors, the study discovered a replicable positive correlation between gender diversity and genetic markers for higher cognitive performance. This suggests that gender-diverse individuals typically have more of these cognitive performance gene variants. Finally, the study presents some early evidence suggesting that interactions between the environment (e.g., stigma) and genetic risk explain some of the elevated risk to mental health in gender-diverse individuals.

Retrospective study of testosterone deficiency and symptom burden in patients with pancreatic cancer.

Background: Pancreatic cancer patients have poor quality of life. Testosterone deficiency is associated with constitutional symptoms and sexual dysfunction which may contribute to poor quality of life. We investigated the prevalence of screening for and presence of testosterone deficiency in male pancreatic cancer patients. Methods: To determine the frequency of screening for testosterone deficiency in pancreatic cancer patients, our institution's electronic medical record system was queried for male patients diagnosed with a pancreatic mass between 2006 and 2020 and an available testosterone level. In a separate analysis, total testosterone was measured in serum samples from a cohort of 89 male pancreatic ductal adenocarcinoma (PDAC) patients. Low serum testosterone was defined as <300 ng/dL. Results: One thousand five hundred and sixty-six male patients were identified with a pancreatic mass, and 35 (2.2%) also had a testosterone level. In our analysis cohort, 44 of 89 patients (49.4%) were found to have low serum testosterone. Symptoms consistent with testosterone deficiency were documented for 70% of these patients, with fatigue being the most common. Testosterone level had no significant association with progression-free survival (PFS) (P=0.66) or overall survival (OS) (P=0.95). Conclusions: Testosterone deficiency is common but rarely assessed in male patients with pancreatic cancer. Further studies are warranted to explore the possibility of testosterone supplementation to improve quality of life in this patient population.

The Wahls Behavior Change Model for Complex Chronic Diseases: A Clinician's Guide.

Behavior change models are used to understand and intervene on health-related behaviors and outcomes. However, there is a gap in the literature regarding how to create and maintain behavior change in patients with complex chronic diseases such as Multiple Sclerosis (MS). To address this gap, the Wahls Behavior ChangeTM Model (WBCM) (The trademark applies to subsequent mention of the model.) was developed based on existing behavior change theory, empirical evidence, and extensive clinical experience caring for patients with complex chronic diseases. A patient-centered, comprehensive, and multimodal approach, this model provides a framework for understanding and implementing lifestyle behavior change. The overall goals of this paper are to: (1) review existing behavior change theories; (2) introduce the WBCM, including the model's 11 Principles for behavior change in patients with complex chronic diseases; and (3) share how providers can be trained to implement the WBCM. The WBCM can potentially improve short- and longer-term function and quality of life outcomes for people with complex chronic diseases.

Diagnostic criteria for enduring sexual dysfunction after treatment with antidepressants, finasteride and isotretinoin.

BACKGROUND: A set of enduring conditions have been reported in the literature involving persistent sexual dysfunction after discontinuation of serotonin reuptake inhibiting antidepressants, 5 alpha-reductase inhibitors and isotretinoin. OBJECTIVE: To develop diagnostic criteria for post-SSRI sexual dysfunction (PSSD), persistent genital arousal disorder (PGAD) following serotonin reuptake inhibitors, post-finasteride syndrome (PFS) and post-retinoid sexual dysfunction (PRSD). METHODS: The original draft was designed using data from two published case series (Hogan et al., 2014 and Healy et al., 2018), which represent the largest public collections of data on these enduring conditions. It was further developed with the involvement of a multidisciplinary panel of experts. RESULTS: A set of criteria were agreed upon for each of the above conditions. Features of PSSD, PFS and PRSD commonly include decreased genital and orgasmic sensation, decreased sexual desire and erectile dysfunction. Ancillary non-sexual symptoms vary depending on the specific condition but can include emotional blunting and cognitive impairment. PGAD presents with an almost mirror image of unwanted sensations of genital arousal or irritability in the absence of sexual desire. A new term, post-SSRI asexuality, is introduced to describe a dampening of sexual interest and pleasure resulting from a pre-natal or pre-teen exposure to a serotonin reuptake inhibitor. CONCLUSIONS: These criteria will help in both clinical and research settings. As with all criteria, they will likely need modification in the light of developments.

Characterizing post-SSRI sexual dysfunction and its impact on quality of life through an international online survey.

BACKGROUND: Post-SSRI sexual dysfunction (PSSD) is an underrecognized and poorly understood medical condition characterized by sexual dysfunction that persists despite SSRI discontinuation. OBJECTIVE: We conducted a survey of individuals with PSSD to better characterize this condition and its impact on various quality of life concerns. METHODS: Surveys were distributed to an online support group for individuals with PSSD. Surveys assessed medications suspected of causing PSSD and symptoms experienced during and after treatment. Respondents reported the trajectory of their condition, the efficacy of different treatments, and the impact of PSSD on their quality of life. RESULTS: 239 survey responses were included in this study. A majority of respondents had a history of SSRI use (92%) compared to only SNRI or atypical antidepressant use (8%). The overall severity of symptoms improved for 45% and worsened or remained the same for 37% of respondents after discontinuing treatment with serotonin reuptake inhibitors. Only 12% of respondents reported being counseled regarding potential sexual dysfunction while taking antidepressants. The majority rated the effect of PSSD on their quality of life as extremely negative (59%) or very negative (23%). CONCLUSION: PSSD can have an overwhelmingly negative impact on quality of life. Currently, it is unclear why certain individuals develop PSSD and there are no definitive treatments for this condition. Further research of PSSD and greater awareness of this condition is needed among prescribers of serotonin reuptake inhibitors to improve patient care.

Lateral herniation during treatment with collagenase Clostridium histolyticum (Xiaflex) for Peyronie's disease.

BACKGROUND: Collagenase Clostridium histolyticum (CCH), also know as Xiaflex, with penile modeling is considered to be the gold standard non-surgical option for management of Peyronie's disease and is known to be safe and efficacious. Corporal rupture is a rare but known adverse event of CCH treatment, however there are limited studies describing corporal herniation without rupture. Here we present a patient who experienced a rare complication following CCH injections for Peyronie's disease: lateral herniation of the tunica albuginea in the setting of a dorsal penile plaque. CASE PRESENTATION: A 58-year-old male presented to our clinic seeking treatment for Peyronie's disease. On exam, he was found to have a palpable dorsal plaque and > 30 degrees leftward curvature of the penis. He was deemed an appropriate candidate for and patient decided to proceed with CCH and modeling. He received 2 cycles of CCH injections (4 total CCH injections) with in-office and at-home penile modeling, per manufacturer's protocol. Two weeks following in-office modeling during his second CCH cycle, the patient reported a painless, soft swelling involving the left side of his penile shaft only occurring with erection. Exam and history were suggestive of lateral herniation rather than corporal rupture. CCH was discontinued. Patient declined further evaluation with penile ultrasound. CONCLUSIONS: This is the first case report detailing lateral herniation with CCH injections. Symptoms and exam that should raise suspicion of corporal herniation are a soft, painless mass with erection.

Spinal Cord Stimulation for Visceral Pain: Present Approaches and Future Strategies.

INTRODUCTION: The introduction of successful neuromodulation strategies for managing chronic visceral pain lag behind what is now treatment of choice in refractory chronic back and extremity pain for many providers in the United States and Europe. Changes in public policy and monetary support to identify nonopioid treatments for chronic pain have sparked interest in alternative options. In this review, we discuss the scope of spinal cord stimulation (SCS) for visceral pain, its limitations, and the potential role for new intradural devices of the type that we are developing in our laboratories, which may be able to overcome existing challenges. METHODS: A review of the available literature relevant to this topic was performed, with particular focus on the pertinent neuroanatomy and uses of spinal cord stimulation systems in the treatment of malignant and nonmalignant gastrointestinal, genitourinary, and chronic pelvic pain. RESULTS: To date, there have been multiple off-label reports testing SCS for refractory gastrointestinal and genitourinary conditions. Though some findings have been favorable for these organs and systems, there is insufficient evidence to make this practice routine. The unique configuration and layout of the pelvic pain pathways may not be ideally treated using traditional SCS implantation techniques, and intradural stimulation may be a viable alternative. CONCLUSIONS: Despite the prevalence of visceral pain, the application of neuromodulation therapies, a standard approach for other painful conditions, has received far too little attention, despite promising outcomes from uncontrolled trials. Detailed descriptions of visceral pain pathways may offer several clues that could be used to implement devices tailored to this unique anatomy.

A Quality Analysis of the Last Decade's Most Heavily Cited Data Relative to Outcomes After Penile Prosthesis Placement.

BACKGROUND: The penile prosthesis has been used for men with erectile dysfunction for nearly 5 decades. Although many articles examine various outcome measures, wide variability exists in the quality of these studies. AIM: We sought to critically evaluate the most referenced literature related to penile prosthesis outcomes over the last 10 years. METHODS: A PubMed search of the indexed English literature was performed using the search terms "prospective," "penile prosthesis," and "outcomes", and all relevant publications from 2009 to 2019 were reviewed. In addition, we performed a Google Scholar search for the same interval using the search term "penile prosthesis outcomes" to evaluate manuscripts which have been most commonly cited. The most heavily cited manuscripts were sorted for relevancy using Google's internal algorithm, and then, the articles were reviewed by the authorship team for appropriateness of the subject matter. Articles with less than 10 citations were excluded. We used the Oxford Center for Evidence-Based Medicine Criteria as part of our evaluation of the published data involving independent research, as opposed to review articles summarizing previously published findings. RESULTS: We evaluated the most-cited literature of the past decade relevant to penile prosthesis outcomes and reported the major findings in regards to infection, erosion, extrusion, device reliability, and satisfaction (both the patient and partner). The majority of these studies are retrospective in nature. CLINICAL IMPLICATIONS: From our review of the most commonly cited studies, there was no high-level evidence published in this area within the last 10 years. There are multiple barriers to producing these types of studies in the evaluation of penile prosthesis outcomes. STRENGTHS & LIMITATIONS: Using the most commonly cited articles allows us to understand the data that are being cited in other new publications. Focusing on the most cited articles on penile prosthesis outcomes in the last 10 years is a limitation as there have been many more studies published in this area. CONCLUSION: While many studies have examined penile prosthesis outcomes, most of the heavily cited literature consists of low-level evidence. Higher quality research is necessary to better assess penile prosthesis outcomes. Chouhan JD, Pearlman AM, Kovell RC, et al.

Unplanned In-Global Clinic Visits, Emergency Department Encounters and Hospital Readmissions following Urological Prosthetic Surgery: Data for Quality Improvement.

INTRODUCTION: Unplanned and potentially avoidable clinic encounters, emergency department visits and readmissions burden the health care system. We identified and characterized unplanned health care utilization during the 90-day global period following urological prosthetic surgery. METHODS: Records of patients undergoing penile prosthesis implantation and/or artificial urinary sphincter placement by a single surgeon between January 2011 and November 2016 were retrospectively reviewed. Unplanned visits to the urology clinic, emergency department and/or hospital for each patient within 90 days of surgery were identified and characterized. RESULTS: Of the 288 surgeries performed during the designated study period 214 were for inflatable penile prosthesis, 59 for artificial urinary sphincter and 15 for a combination. There were 58 unplanned in-global clinic encounters, 13 emergency department visits and 7 hospital readmissions. Unplanned clinic visits were most common for additional teaching, voiding issues and incision concerns, presenting an average of 39 days postoperatively. Emergency department visits were most commonly due to voiding issues and incision concerns, presenting an average of 25 days postoperatively. Hospital readmissions were most common for complications and incision concerns, presenting an average of 23 days postoperatively. CONCLUSIONS: Most unplanned visits during the 90-day global period following urological prosthetic surgery do not require hospital readmission. Improved preoperative counseling, instruction before hospital discharge and/or scheduled phone contact with patients during recovery may reduce unnecessary resource use.

Histopathology of Anterior Urethral Strictures: Toward a Better Understanding of Stricture Pathophysiology.

PURPOSE: Histopathology can provide insights into disease mechanisms but to date it has been poorly described for urethral stricture. The purpose of this study was to comprehensively describe histopathological findings of stricture specimens obtained at the time of anterior urethroplasty. MATERIALS AND METHODS: All pathological specimens of men who underwent anterior urethroplasty of urethral stricture disease from 2010 to 2017 at a single institution were rereviewed by a single blinded pathologist directed to rule out lichen sclerosus and then describe inflammatory cell type and severity when present. Cohorts comprising strictures with no inflammation, minimal to mild inflammation or moderate to severe inflammation were developed and stricture, patient and surgical outcome characteristics were compared. RESULTS: Histopathology slides from 100 anterior urethroplasty cases were reviewed. Two or more lichen sclerosus characteristics were present in 21% of specimens and 44% of specimens showed chronic inflammation, which was minimal in 20%, mild in 39%, moderate in 39% and severe in 2%. Lymphocytes in 86% of specimens and plasma cells in 12% were the predominant cell types. Patients with inflammatory stricture reported worse overall health. Inflammation was largely absent from isolated bulbomembranous strictures (9%) and more common in lichen sclerosus strictures (100%). The 11% overall failure rate was not affected by the presence (7%) or absence (14%) of inflammation. CONCLUSIONS: Chronic inflammation is prevalent in a significant percent of urethral stricture disease specimens. Associations with worse overall health suggest systemic mediators. Absent inflammation in bulbomembranous strictures suggests a unique pathophysiology in this region. The presence of inflammation did not affect surgical outcomes at mid-term followup.

Infection following penile prosthesis placement at an academic training center remains low despite involvement of surgeons-in-training.

Purpose: Primary care providers harbor misconceptions regarding penile prosthetic surgery, largely overestimating the rate of infection. Rates of infection following surgery for primary placement and revision are estimated as 1% to 3% and 10% to 18%, respectively. Our objective was to determine the contemporary incidence of infection following inflatable penile prostheses surgery at an academic training center where surgeons-in-training are routinely involved. Materials and Methods: Review of a prospectively collected single-surgeon database was performed. All cases of inflatable penile prostheses placement from January 2011 through June 2017 were reviewed. Information regarding training level of assistant surgeon(s) was collected, and follow-up data was compiled regarding postoperative infections and need for revision surgery. Results: Three hundred nine cases meeting inclusion criteria were identified. Mean patient age was 64.2 years, and mean follow-up was 28.7 months. Distribution involved 257 (83.2%) for primary placement, 45 (14.6%) for removal/replacement, and 7 (2.3%) in setting of prior device removal. Diabetes was noted in 31.1% of men. Surgeon-in-training involvement was noted in 100% of cases. Infection was confirmed in a patient who had skin breakdown over an area of corporal reconstruction with polytetrafluoroethylene. The overall postoperative infection rate was 0.3%. Conclusions: In this series from an academic training center, infection following penile prosthetic surgery is low, similar to other centers of excellence, even with 100% involvement of surgeons-in-training. This data should be used to better inform primary care providers and members of the general public potentially interested in restoration of sexual function.

Diagnosis and Treatment of Urethrocavernous Fistula Presenting as Urethral Bleeding.

Urethrocavernous fistula is rarely reported, though should be considered within the differential diagnosis for men who present with urethral bleeding, particularly at time of erection. Ultrasonography with concomitant intracavernosal injection can be considered to confirm the diagnosis. Here we report a case of urethrocavernous fistula in a 48 year old man without preceding traumatic event.

Proximal Corporal Perforation During Penile Prosthesis Surgery: Prevention, Recognition, and Review of Historical and Novel Management Strategies.

BACKGROUND: Proximal corporal perforation at time of dilation, although rare, may occur due to factors related to patient anatomy, presence of intra-cavernosal fibrosis, and/or surgical technique. AIM: To describe tools and techniques designed to prevent and identify proximal corporal perforation, and maneuvers to minimize the risk of subsequent cylinder migration once proximal perforation has been recognized, such that the operation may proceed and result in an acceptable outcome. METHODS: We discuss tips for prevention, recognition, and management of proximal corporal perforation by presenting a review of the literature as well as our preferences based on a high-volume experience with penile prosthesis surgery. OUTCOMES: Described techniques aim to minimize risk of cylinder migration in the absence of true proximal repair. RESULTS: Although proximal perforation may be obvious at times, particularly with a sudden loss of resistance during dilation, discrepant corporal measurements and/or dissimilar proximal deflection of the dilator should also increase the index of suspicion. Numerous techniques have been employed to theoretically reduce the risk of cylinder migration in the setting of proximal corporal perforation. These include formal corporal repair (historical), windsock repairs with non-absorbable grafts, absorbable plugs, and suture fixation of the rear tip extender or shod material covering implant tubing. CLINICAL TRANSLATION: Intra-operative recognition of proximal corporal perforation, coupled with understanding of surgical strategies to minimize the risk of future device migration, may allow completion of an operation that still results in an optimal outcome. CONCLUSIONS: Techniques described to prevent proximal migration are not strongly evidence-based, but rooted in logic and supported by high-volume implanters. Intra-operative perforation of the proximal corpora, although rare, can threaten the success of penile implant surgery, though the techniques described herein have been developed to mitigate the potential for subsequent device migration, allowing surgery to proceed and to achieve the desired clinical result.

Safety and feasibility of platelet rich fibrin matrix injections for treatment of common urologic conditions.

Purpose: Autologous platelet rich plasma (PRP) is used increasingly in a variety of settings. PRP injections have been used for decades to improve angiogenesis and wound healing. They have also been offered commercially in urology with little to no data on safety or efficacy. PRP could theoretically improve multiple urologic conditions, such as erectile dysfunction (ED), Peyronie's disease (PD), and stress urinary incontinence (SUI). A concern with PRP, however, is early washout, a situation potentially avoided by conversion to platelet rich fibrin matrix (PRFM). Before clinical trials can be performed, safety analysis is desirable. We reviewed an initial series of patients receiving PRFM for urologic pathology to assess safety and feasibility. Materials and Methods: Data were reviewed for patients treated with PRFM at our center from November 2012 to July 2017. Patients were observed immediately post-injection and at follow-up for complications and tolerability. Where applicable, International Index of Erectile Function (IIEF-5) scores were reviewed before and after injections for ED and/or PD. Pad use data was collected pre/post injection for SUI. Results: Seventeen patients were identified, with a mean receipt of 2.1 injections per patient. Post-procedural minor adverse events were seen in 3 men, consisting of mild pain at injection site and mild penile bruising. No patients experienced complications at follow-up. No decline was observed in men completing pre/post IIEF-5 evaluations. Conclusions: PRFM appears to be a safe and feasible treatment modality in patients with urologic disease. Further placebo-controlled trials are warranted.

Testosterone replacement therapy in patients with prostate cancer after radical prostatectomy.

PURPOSE: Testosterone replacement therapy in men with prostate cancer is controversial, with concern that testosterone can stimulate cancer growth. We evaluated the safety and efficacy of testosterone in hypogonadal men with prostate cancer treated with radical prostatectomy. MATERIALS AND METHODS: We performed a review of 103 hypogonadal men with prostate cancer treated with testosterone after prostatectomy (treatment group) and 49 nonhypogonadal men with cancer treated with prostatectomy (reference group). There were 77 men with low/intermediate (nonhigh) risk cancer and 26 with high risk cancer included in the analysis. All men were treated with transdermal testosterone, and serum hormone, hemoglobin, hematocrit and prostate specific antigen were evaluated for more than 36 months. RESULTS: Median (IQR) patient age in the treatment group was 61.0 years (55.0-67.0), and initial laboratory results included testosterone 261.0 ng/dl (213.0-302.0), prostate specific antigen 0.004 ng/ml (0.002-0.007), hemoglobin 14.7 gm/dl (13.3-15.5) and hematocrit 45.2% (40.4-46.1). Median followup was 27.5 months, at which time a significant increase in testosterone was observed in the treatment group. A significant increase in prostate specific antigen was observed in the high risk and nonhigh risk treatment groups with no increase in the reference group. Overall 4 and 8 cases of cancer recurrence were observed in treatment and reference groups, respectively. CONCLUSIONS: Thus, testosterone therapy is effective and, while followed by an increase in prostate specific antigen, does not appear to increase cancer recurrence rates, even in men with high risk prostate cancer. However, given the retrospective nature of this and prior studies, testosterone therapy in men with history of prostate cancer should be performed with a vigorous surveillance protocol.

Optimal emergency personnel allocation after a natural disaster.

OBJECTIVE: Little work has been devoted to the links between natural disasters, subsequent Emergency Medical Services (EMS) network utilization, triage, and public awareness. The aim of this study was to investigate the types and distribution of emergency calls recorded after each South Florida hurricane during the 2005 season, identifying target areas for public health education, and emergency personnel use and training. DESIGN: Retrospective database review. SETTING: Miami-Dade Fire Rescue (MDFR) emergency dispatch headquarters. PATIENTS, PARTICIPANTS: All persons making 911 phone calls to the MDFR emergency dispatch headquarters in the 3 days before and after category 3 or higher hurricanes during 2005. INTERVENTIONS: None. RESULTS: There were 192,363 emergencies reported in 2005. The mean number of 911 emergencies reported per day for the 3 days before and after Katrina was 503 +/- 26 and 819 +/- 105, respectively (p = 0.007). The mean number for Wilma was 533 +/- 42 before and 800 +/- 63 after (p = 0.004). However, Rita had no impact on the number of 911 emergencies reported. Katrina resulted in a statistically significant increase in 911 calls for breathing (p = 0.03), convulsions and seizures (p = 0.02), and hazardous situations (p = 0.04). Rita led to an increase in convulsions and seizures (p = 0.03). Lastly, Wilma caused a rise in breathing emergencies (p = 0.02) and hazardous situations (p = 0.02). CONCLUSIONS: This study suggests that 911 calls regarding respiratory complaints, convulsions, seizures, and hazardous situations can be expected to significantly increase after a hurricane. Educational initiatives, EMS resource allocation, and modified triage systems designed to target these areas may limit EMS system-wide strain and improve health outcomes following natural disasters.
