Percutaneous decannulation reduces procedure length and rates of groin wound infection in patients on venoarterial extracorporeal membrane oxygenation.

Objective: Open decannulation from femoral venoarterial extracorporeal membrane oxygenation (VA-ECMO) carries high risk of morbidity, including groin wound infection. This study evaluated the impact of percutaneous decannulation on rates of groin wound infection in patients decannulated from femoral VA-ECMO. Methods: Between January 1, 2022, and April 30, 2023, 47 consecutive patients received percutaneous femoral VA-ECMO and survived to decannulation. A percutaneous suture-mediated closure device was used for decannulation in patients with relatively smaller arterial cannulas. Patients with larger arterial cannulas or unsuccessful percutaneous closures underwent surgical cutdown and repair of the femoral artery. The primary outcome was arterial site wound infection following decannulation. Results: Among the 47 patients who survived to decannulation from VA-ECMO, 21 underwent percutaneous decannulation and 27 underwent surgical cutdown. One patient underwent 2 VA-ECMO runs, one with percutaneous decannulation and one with surgical cutdown. Percutaneous decannulation was attempted in 22 patients, with 21 of 22 (95.5%) success rate. Decannulation procedure length was significantly shorter in the percutaneous group (79 minutes vs 148 minutes, P = .0001). The percutaneous group had significantly reduced rates of groin wound complications (0% vs 40.7%, P = .001) and groin wound infections (0% vs 22.2%, P = .03) when compared with the surgical cutdown group. Three patients (14.3%) in the percutaneous group experienced vascular complications, including pseudoaneurysm at the distal perfusion catheter site and nonocclusive thrombus of the common femoral artery. Conclusions: Percutaneous decannulation may reduce decannulation procedure length and rate of groin wound infection in patients who survive to decannulation from VA-ECMO.

Surgically implanted endovascular, microaxial left ventricular assist device: A single institution study.

Objective: The Impella 5.5 (Abiomed, Inc), a surgically implanted endovascular microaxial left ventricular assist device, is increasingly used worldwide and there have been more than 10,000 implants. The purpose of this study is to describe a large-volume, single-center experience with the use of the Impella 5.5. Methods: Data were obtained retrospectively from patients supported with the Impella 5.5 implanted at our institution from May 1, 2020, to December 31, 2022. Demographic, operative, and postoperative outcomes for each group are described. Results are reported in median (interquartile range) or n (%). The entire cohort was divided into 5 main groups based on the intention to treat at the time of the Impella 5.5 implantation: (1) patients who had a planned Impella 5.5 implanted at the time of high-risk cardiac surgery; (2) patients with cardiogenic shock; (3) patients bridged to a durable left ventricular assist device; (4) patients bridged to transplant; and (5) patients with postcardiotomy shock who received an unplanned Impella 5.5 implant. Results: A total of 126 patients were supported with the Impella 5.5. Overall survival to device explant was 76.2%, with 67.5% surviving to discharge. Midterm survival was assessed with a median follow-up time of 318 days and demonstrated an overall survival of 60.3% and a median of 650 days (549-752). Conclusions: Outcomes after using the Impella 5.5 are variable depending on the indication of use. Patient selection may be of utmost importance and requires further experience with this device to determine who will benefit from insertion.

[Special Consultation Hour for Patients with Cancer-Related Fatigue: Study Protocol of an Observational Study of a Nationwide Health Care Structure by the Bavarian Cancer Society (BKG) in Bavaria]. / Tumor-Fatigue-Sprechstunde der Bayerischen Krebsgesellschaft e.V.: Studienprotokoll einer Beobachtungsstudie zur flächendeckenden Versorgungsstruktur in Bayern.

Cancer-related fatigue (CRF) is a burdensome condition of persistent tiredness, weakness, and lack of energy on physical, emotional, and cognitive level. CRF occurs in the context of cancer and/or its therapy and correlates with limitations in everyday life functioning, quality of life, and survival time. Up to now, medical care in Germany is inadequate. German wide institutions are lacking, which are specialised in identifying treatable factors influencing CRF as well as in counselling of adequate, evidence-based treatments. Since 2013, the Bavarian Cancer Society (BCS) implemented a nationwide health care structure with ten psychosocial cancer counselling centers in Bavaria. At these locations, the BCS offers for cancer patients with CRF special consultation hours with well-founded diagnostic and guidance. During the conception and further development of the consultation hour, all relevant guidelines have been considered. All consultation hours are directed by physicians with oncological and psycho-oncological experience. All of them took part in an extensive CRF training. The aim of this prospective, multicentre, observational study is the evaluation of the actual state of the TF-consultation including the analyses of offer and need for TF-consultation hours, of patient-reported TF before TF-consultation and ten weeks later, of realization of the recommended interventions to reduce TF as well as the analysis of strengths and potentials for improvement of the current system. The results will help to implement a German wide care structure.

Increased severe primary graft dysfunction in left ventricular assist device patients following united network for organ sharing allocation changes.

INTRODUCTION: In 2018, the United Network for Organ Sharing (UNOS) implemented a new heart allocation system which prioritized patients on temporary support devices and left-ventricular assist device (LVAD) patients with complications. These changes have the potential to impact outcomes for patients bridged to transplant with an LVAD. METHODS: We performed a retrospective study of 168 adult heart transplant recipients at our center between 2016 and 2020 evaluating post-transplant outcomes before and after UNOS allocation changes. Donor and recipient data were retrieved from chart review and national databases. The primary outcome of this study was severe primary graft dysfunction (PGD) with secondary outcomes of 30-day readmission, 30-day mortality, and 1-year mortality. RESULTS: Incidence of severe PGD was similar in the overall cohort before and after the changes (10% vs. 15%, respectively, p = .3) and increased in the LVAD-bridged cohort (12% vs. 40%, respectively, p < .01). Secondary outcomes of readmission and survival were similar between all groups. Blood transfusion was predictive of severe PGD in multivariable modeling (OR 1.3 [1.11-1.59], p < .01).

Improvements in Extracorporeal Membrane Oxygenation for Primary Graft Failure After Heart Transplant.

BACKGROUND: Severe primary graft failure is a life-threatening complication of heart transplantation that may require venoarterial extracorporeal membrane oxygenation (VA-ECMO) support. Surgical practices and management strategies regarding VA-ECMO vary between and within centers. METHODS: We performed a single-center retrospective cohort study on adult patients who received VA-ECMO for primary graft failure between 2013 and 2020. Clinical data were obtained from chart review and national databases. Patients were stratified by transplantation before or after 2017, when our center adopted additional objective criteria for VA-ECMO, adopted partial-flow support, and changed from central cannulation to chimney graft arterial cannulation of brachiocephalic, axillary, or aorta. The primary outcome was survival to device weaning. Secondary outcomes were survival to discharge, survival to 1 year, complications on support, and time to sedation weaning and extubation. RESULTS: From 276 heart transplant recipients, 39 severe primary graft failure patients requiring VA-ECMO were identified. Incidence of graft failure was 13% (n = 18 of 135) pre-2017 and 15% (n = 21 of 141) post-2017. Survival at all time points improved significantly after 2017, with greatest difference in survival to device weaning (61% pre-2017 vs 100% post-2017). After controlling for other factors in multivariable Cox regression modeling, transplantation after 2017 was a predictor of reduced mortality (hazard ratio, 0.209; 95% CI, 0.06-0.71; P = .01). Significant differences were not observed in other secondary outcomes of recovery. CONCLUSIONS: The new VA-ECMO strategy displayed reasonable survival and a remarkable improvement from the prior system.

Self-reported fatigue in patients with rheumatoid arthritis compared to patients with cancer: results from two large-scale studies.

Fatigue is a common symptom in patients with rheumatoid arthritis (RA) and in patients with cancer (CA). The aim was to investigate the degree of fatigue in RA patients as compared to CA patients as well as potential influencing factors on RA-related fatigue. This was a retrospective analyses of two prospective cohort studies that used the EORTC QLQ-FA12 as a common instrument to assess fatigue. The cohort of RA patients was based on a nationwide survey in Germany. The cohort of CA patients was recruited in the context of an international validation field study. Multivariable ANCOVAs compared levels of fatigue between the two cohorts, also including various subgroup analyses. Regression analyses explored influencing factors on RA patients' fatigue. Data of n = 705 RA patients and of n = 943 CA patients were available for analyses. RA patients reported significantly higher Physical Fatigue (mean difference = 7.0, 95% CI 4.2-9.7, p < 0.001) and Social Sequelae (mean difference = 7.5, 95% CI 4.7-10.2, p < 0.001). CA patients reported higher Cognitive Fatigue (mean difference = 3.5, 95% CI 1.4-5.6, p = 0.001). No differences in Emotional Fatigue (p = 0.678) and Interference with Daily Life (p = 0.098) were found. In RA patients, mental health and pain were associated with fatigue (p values < 0.001). RA patients showed a considerable level of fatigue that is comparable to and in certain cases even higher than that of CA patients. The implementation of standardized diagnostic procedures and interventions to reduce fatigue in RA patients are recommended.

[Cancer-related fatigue and immune checkpoint inhibitors]. / Tumorassoziierte Fatigue bei Immuncheckpointinhibitoren.

Cancer-related fatigue (CRF) is a common, burdensome, debilitating subjective sense of tiredness or exhaustion in patients with cancer. The pathogenesis is assumed to be multifactorial with CRF being a final common pathway. Among other things, treatment with immune checkpoint inhibitors (ICI) is also associated with CRF. However, the toxic adverse events of ICI are not inevitably the only cause for CRF. Therefore, the diagnostic procedure should address other possible influencing factors, e.g., somatic, mental, cognitive, and psychosocial causes. To manage CRF evidence-based, causal, and symptomatic therapies are available. The key condition to manage CRF is active listening and shared decision making (SDM) with the goal to select those interventions from the broad spectrum of therapies that are best suited for the particular patient and their life circumstances. Providing information about ICI and CRF to reassure patients is already an effective intervention.

Acute kidney injury post-heart transplant: An analysis of peri-operative risk factors.

Acute kidney injury is a common complication following heart transplantation, and the factors contributing to acute kidney injury are not well understood. We conducted a retrospective cohort study evaluating patients who underwent heart transplantation between 2009 and 2016 at a single institution. The primary endpoint was incidence of acute kidney injury as defined by Kidney Disease Improving Global Outcomes criteria. Secondary endpoints included 30-day hospital readmission, 30-day mortality, and 1-year mortality. A total of 228 heart transplant patients were included in the study for analysis. In total, 145 (64%) developed acute kidney injury, where 43 (30%) were classified as stage I, 28 (19%) as stage II, and 74 (51%) as stage III. Risk factors found to be associated with the presence of acute kidney injury included increased use of vasopressors and inotropes post-transplant. Protective factors included cardiopulmonary bypass time <170 min. Acute kidney injury was found to be associated with increased 30-day and 1-year mortality.

Extracorporeal Life Support for Cardiogenic Shock With Either a Percutaneous Ventricular Assist Device or an Intra-Aortic Balloon Pump.

Extracorporeal life support (ECLS) can result in complications due to increased left ventricular (LV) afterload. The percutaneous ventricular assist device (PVAD) and intra-aortic balloon pump (IABP) are both considered to be effective means of LV unloading. This study describes the efficacy of LV unloading and related outcomes with PVAD or IABP during ECLS. From January 2010 to April 2018, all cardiogenic shock patients who underwent ECLS plus simultaneous PVAD or IABP were analyzed. Forty-nine patients received ECLS + PVAD, while 91 received ECLS + IABP. At 48 hours, mean pulmonary artery pressure was significantly reduced in both groups [34 mm Hg to 22, p < 0.01; 32 mm Hg to 21, p < 0.01; ECLS + PVAD and ECLS + IABP group, respectively]. The two groups had similar 30 day survival rates [19 patients (39%) vs. 35 (39%), p = 0.56]. The ECLS + PVAD group had higher incidences of bleeding at the insertion site [11 (22%) vs. 0, p < 0.01] and major hemolysis [9 (18%) vs. 0, p < 0.01]. Both groups had improvement in LV end-diastolic dimension (61 ± 12 mm to 54 ± 12, p = 0.03; 60 ± 12 mm to 47 ± 10, p < 0.01), and LV ejection fraction (16 ± 7% to 22 ± 10, p < 0.01; 22 ± 12% to 29 ± 15, p = 0.01). Both ECLS + PVAD and ECLS + IABP effectively reduced pulmonary artery pressure and improved LV function. Bleeding at the PVAD or IABP insertion site occurred more frequently in the ECLS + PVAD group than the ECLS + IABP group (p < 0.01). Nine patients (18%) in the ECLS + PVAD group experienced major hemolysis, while there was no hemolysis in the ECLS + IABP group (p < 0.01). Careful considerations are required before selecting an additional support to ECLS.

The impact of uncorrected mild aortic insufficiency at the time of left ventricular assist device implantation.

OBJECTIVE: The study objective was to investigate the progression of uncorrected mild aortic insufficiency and its impact on survival and functional status after left ventricular assist device implantation. METHODS: We retrospectively reviewed 694 consecutive patients who underwent implantation of a continuous-flow left ventricular assist device between January 2006 and March 2018. Pre-left ventricular assist device transthoracic echocardiography identified 111 patients with mild aortic insufficiency and 493 patients with trace or no aortic insufficiency. To adjust for differences in preoperative factors, propensity score matching was used, resulting in 101 matched patients in each of the mild aortic insufficiency and no aortic insufficiency groups. RESULTS: Although both groups showed similar survival (P = .58), the mild aortic insufficiency group experienced higher incidence of readmission caused by heart failure (hazard ratio, 2.62; 95% confidence interval, 1.42-4.69; P < .01). By using the mixed effect model, pre-left ventricular assist device mild aortic insufficiency was a significant risk factor for both moderate or greater aortic insufficiency and worsening New York Heart Association functional status (P < .01). CONCLUSIONS: Patients with uncorrected mild aortic insufficiency had a higher risk of progression to moderate or greater aortic insufficiency after left ventricular assist device implantation with worse functional status and higher incidence of readmission caused by heart failure compared with patients without aortic insufficiency. Further investigations into the safety and efficacy of concomitant aortic valve procedures for mild aortic insufficiency at the time of left ventricular assist device implant are warranted to improve patients' quality of life, considering the longer left ventricular assist device use as destination therapy and bridge to transplant with the new US heart allocation system.

Clinical Outcomes and Reduced Pulmonary Artery Pressure With Intra-Aortic Balloon Pump During Central Extracorporeal Life Support.

Patients supported with extracorporeal life support (ECLS) can experience severe complications from increased left ventricular afterload. The intra-aortic balloon pump (IABP) is thought to unload the left ventricle (LV) and is routinely used with ECLS despite conflicting evidence of its clinical benefit. This retrospective, single-center study examined the effect of the simultaneous use of IABP and centrally cannulated ECLS on patient outcomes and provides new insights into IABP-mediated LV unloading. Thirty patients supported with central ECLS and IABP (extracorporeal life support-IABP group, ECLS-I) were compared with 30 patients with central ECLS alone (ECLS) for cardiogenic shock. Rates of survival to 30 days (p = 0.06) and intensive care unit (ICU) discharge (p = 0.17), and clinical outcomes were not significantly different between the two groups. In patients with pulmonary artery pressure monitoring, mean pulmonary artery (PA) pressure was significantly reduced after 24 (p = 0.007) and 48 hours (p = 0.002) in the ECLS-I group. No significant difference in PA pressure was observed in the ECLS group after 24 or 48 hours. The IABP has the ability to reduce pulmonary artery pressure in patients supported by central ECLS. However, this did not translate into improved survival or clinical outcomes in our population.

A randomized controlled trial of directive and nondirective smoking cessation coaching through an employee quitline.

BACKGROUND: Telephone quitlines can help employees quit smoking. Quitlines typically use directive coaching, but nondirective, flexible coaching is an alternative. Call-2-Quit used a worksite-sponsored quitline to compare directive and nondirective coaching modes, and evaluated employee race and income as potential moderators. METHODS: An unblinded randomized controlled trial compared directive and nondirective telephone coaching by trained laypersons. Participants were smoking employees and spouses recruited through workplace smoking cessation campaigns in a hospital system and affiliated medical school. Coaches were four non-medical women trained to use both coaching modes. Participants were randomized by family to coaching mode. Participants received up to 7 calls from coaches who used computer assisted telephone interview software to track topics and time. Outcomes were reported smoking abstinence for 7 days at last contact, 6 or 12 months after coaching began. Both worksites implemented new tobacco control policies during the study. RESULTS: Most participants responded to an insurance incentive introduced at the hospital. Call-2-Quit coached 518 participants: 22 % were African-American; 45 % had incomes below $30,000. Income, race, and intervention did not affect coaching completion rates. Cessation rates were comparable with directive and nondirective coaching (26 % versus 30 % quit, NS). A full factorial logistic regression model identified above median income (odds ratio = 1.8, p = 0.02), especially among African Americans (p = 0.04), and recent quit attempts (OR = 1.6, p = 0.03) as predictors of cessation. Nondirective coaching was associated with high cessation rates among subgroups of smokers reporting income above the median, recent quit attempts, or use of alternative therapies. Waiting up to 4 weeks to start coaching did not affect cessation. Of 41 highly addicted or depressed smokers who had never quit more than 30 days, none quit. CONCLUSION: Nondirective coaching improved cessation rates for selected smoking employees, but less expensive directive coaching helped most smokers equally well, regardless of enrollment incentives and delays in receiving coaching. Some subgroups had very low cessation rates with either mode of quitline support. TRIAL REGISTRATION: ClinicalTrials.gov NCT02730260 , Registered March 31, 2016.

Methods for Performing Survival Curve Quality-of-Life Assessments.

BACKGROUND: Many medical decisions involve an implied choice between alternative survival curves, typically with differing quality of life. Common preference assessment methods neglect this structure, creating some risk of distortions. METHODS: Survival curve quality-of-life assessments (SQLA) were developed from Gompertz survival curves fitting the general population's survival. An algorithm was developed to generate relative discount rate-utility (DRU) functions from a standard survival curve and health state and an equally attractive alternative curve and state. A least means squared distance algorithm was developed to describe how nearly 3 or more DRU functions intersect. These techniques were implemented in a program called X-Trade and tested. RESULTS: SQLA scenarios can portray realistic treatment choices. A side effect scenario portrays one prototypical choice, to extend life while experiencing some loss, such as an amputation. A risky treatment scenario portrays procedures with an initial mortality risk. A time trade scenario mimics conventional time tradeoffs. Each SQLA scenario yields DRU functions with distinctive shapes, such as sigmoid curves or vertical lines. One SQLA can imply a discount rate or utility if the other value is known and both values are temporally stable. Two SQLA exercises imply a unique discount rate and utility if the inferred DRU functions intersect. Three or more SQLA results can quantify uncertainty or inconsistency in discount rate and utility estimates. Pilot studies suggested that many subjects could learn to interpret survival curves and do SQLA. LIMITATIONS: SQLA confuse some people. Compared with SQLA, standard gambles quantify very low utilities more easily, and time tradeoffs are simpler for high utilities. When discount rates approach zero, time tradeoffs are as informative and easier to do than SQLA. CONCLUSIONS: SQLA may complement conventional utility assessment methods.

Cancer-related fatigue: epidemiology, pathogenesis, diagnosis, and treatment.

BACKGROUND: Many cancer patients suffer from cancer-related fatigue (CRF) both during and after their treatment. CRF can arise at any point in the course of the disease and can be either self-limited or persistent, sometimes for years. It gives rise to a vicious circle of impaired physical performance, avoidance of exertion, inactivity, inadequate physical recovery, helplessness, and depressed mood. Its hallmarks are tiredness, exhaustion, and lack of energy; it can impair performance so severely that the patient is unable to work. It is associated with increased mortality. Cancer patients are hardly ever systematically asked about the symptoms and signs of CRF. The stress and impairments that it produces are often inadequately appreciated, and the opportunities for treatment often neglected. METHOD: Selective review of the pertinent literature, including published guidelines from Germany and abroad. RESULTS: The pathogenesis of CRF is complex, involving an interaction of somatic, emotional, cognitive, and psychosocial factors, with a highly variable pattern of clinical expression. Clinical history-taking plays a key role in diagnostic assessment. Depressive disorders must be considered in the differential diagnosis. Many randomized trials and meta-analyses have documented the efficacy of pharmacological and non-pharmacological treatments for CRF. CONCLUSION: Cancer-related fatigue is a serious problem that impairs patients physically, mentally, and socially. Physicians need to know how to recognize and treat it.

Patterns and predictors of inpatient falls and fall-related injuries in a large academic hospital.

OBJECTIVES: Most research on hospital falls has focused on predictors of falling, whereas less is known about predictors of serious fall-related injury. Our objectives were to characterize inpatients who fall and to determine predictors of serious fall-related injury. METHODS: We performed a retrospective observational study of 1,082 patients who fell (1,235 falls) during January 2001 to June 2002 at an urban academic hospital. Multivariate analysis of potential risk factors for serious fall-related injury (vs no or minor injury) included in the hospital's adverse event reporting database was conducted with logistic regression to calculate adjusted odds ratios (aORs) with 95% confidence intervals (CI95) RESULTS: The median age of patients who fell was 62 years (interquartile range, 49-77 years), 50% were women, and 20% were confused. The hospital fall rate was 3.1 falls per 1,000 patient-days, which varied by service from 0.86 (women and infants) to 6.36 (oncology). Some (6.1%) of the falls resulted in serious injury, ranging by service from 3.1% (women and infants) to 10.9% (psychiatry). The most common serious fall-related injuries were bleeding or laceration (53.6%), fracture or dislocation (15.9%), and hematoma or contusion (13%). Patients 75 years or older (aOR, 3.2; CI95, 1.3-8.1) and those on the geriatric psychiatry floor (aOR, 2.8; CI95, 1.3-6.0) were more likely to sustain serious fall-related injuries. CONCLUSIONS: There is considerable variation in fall rates and fall-related injury percentages by service. More detailed studies should be conducted by floor or service to identify predictors of serious fall-related injury so that targeted interventions can be developed to reduce them.

A case-control study of patient, medication, and care-related risk factors for inpatient falls.

OBJECTIVE: To comprehensively analyze potential risk factors for falling in the hospital and describe the circumstances surrounding falls. DESIGN: Case-control study. Data on potential risk factors and circumstances of the falls were collected via interviews with patients and/or nurses and review of adverse event reports, medical records, and nurse staffing records. SETTING: Large urban academic hospital. PATIENTS: Ninety-eight inpatients who fell and 318 controls matched on approximate length of stay until the index fall. MEASUREMENTS AND MAIN RESULTS: In a multivariate model of patient-related, medication, and care-related variables, factors that were significantly associated with an increased risk of falling included: gait/balance deficit or lower extremity problem (adjusted odds ratio [aOR], 9.0; 95% confidence interval [CI], 2.0 to 41.0), confusion (aOR, 3.6; 95% CI, 1.6 to 8.4), use of sedatives/hypnotics (aOR, 4.3; 95% CI, 1.6 to 11.5), use of diabetes medications (aOR, 3.2; 95% CI, 1.3 to 7.9), increasing patient-to-nurse ratio (aOR, 1.6; 95% CI, 1.2 to 2.0), and activity level of "up with assistance" compared with "bathroom privileges" (aOR, 8.7; 95% CI, 2.3 to 32.7). Urinary or stool frequency or incontinence was of borderline significance (aOR, 2.3; 95% CI, 0.99 to 5.6). Having one or more side rails raised was associated with a decreased risk of falling (aOR, 0.006; 95% CI, 0.001 to 0.024). CONCLUSIONS: Patient health status, especially abnormal gait or lower extremity problems, medications, as well as care-related factors, increase the risk of falling. Fall prevention programs should target patients with these risk factors and consider using frequently scheduled mobilization and toileting, and minimizing use of medications related to falling.

Lifetime and 12-month prevalence of psychiatric disorders in 8,169 male Vietnam War era veterans.

OBJECTIVE: This study reports the prevalence of psychiatric disorders among a nationally distributed sample of Vietnam Era veterans assessed using standardized psychiatric interviewing methods. METHODS: In 1992, the National Institute of Mental Health Diagnostic Interview Schedule was administered by telephone to 8,169 middle-aged males who served in the military during the Vietnam era (1965-1975). RESULTS: Approximately 72% of respondents reported a lifetime history and 36% reported a 12-month history of at least one psychiatric disorder. The most prevalent psychiatric disorders included alcohol abuse and/or dependence (54% lifetime, 17% 12 month), nicotine dependence (48% lifetime, 22% 12 month), and posttraumatic stress disorder (10% lifetime, 4.5% 12 month). CONCLUSIONS: Because of possible participation bias, these results likely represent conservative estimates of psychiatric disorder prevalences among the more than eight million Vietnam Era veterans and reinforces the major public health challenge of preventing, identifying, and treating psychiatric illness in American veterans.

Characteristics and circumstances of falls in a hospital setting: a prospective analysis.

OBJECTIVE: To describe the epidemiology of hospital inpatient falls, including characteristics of patients who fall, circumstances of falls, and fall-related injuries. DESIGN: Prospective descriptive study of inpatient falls. Data on patient characteristics, fall circumstances, and injury were collected through interviews with patients and/or nurses and review of adverse event reports and medical records. Fall rates and nurse staffing levels were compared by service. SETTING: A 1,300-bed urban academic hospital over 13 weeks. PATIENTS: All inpatient falls reported for medicine, cardiology, neurology, orthopedics, surgery, oncology, and women and infants services during the study period were included. Falls in the psychiatry service and falls during physical therapy sessions were excluded. MEASUREMENTS AND MAIN RESULTS: A total of 183 patients fell during the study period. The average age of patients who fell was 63.4 years (range 17 to 96). Many falls were unassisted (79%) and occurred in the patient's room (85%), during the evening/overnight (59%), and during ambulation (19%). Half of the falls (50%) were elimination related, which was more common in patients over 65 years old (83% vs 48%; P <.001). Elimination-related falls increased the risk of fall-related injury (adjusted odds ratio, 2.4; 95% confidence interval 1.1 to 5.3). The medicine and neurology services had the highest fall rates (both were 6.12 falls per 1,000 patient-days), and the highest patient to nurse ratios (6.5 and 5.3, respectively). CONCLUSIONS: Falls in the hospital affect young as well as older patients, are often unassisted, and involve elimination-related activities. Further studies are necessary to prevent hospital falls and reduce fall injury rates.
