Service and Education: The Association Between Workload, Patient Complexity, and Teaching on Internal Medicine Inpatient Services

Population-Based Trends in Complexity of Hospital Inpatients

Importance

Clinical experience suggests that hospital inpatients have become more complex over time, but few studies have evaluated this impression.

Objective

To assess whether there has been an increase in measures of hospital inpatient complexity over a 15-year period.

Design, Setting and Participants

This cohort study used population-based administrative health data from nonelective hospitalizations from April 1, 2002, to January 31, 2017, to describe trends in the complexity of inpatients in British Columbia, Canada. Hospitalizations were included for individuals 18 years and older and for which the most responsible diagnosis did not correspond to pregnancy, childbirth, the puerperal period, or the perinatal period. Data analysis was performed from July to November 2023.

Exposure

The passage of time (15-year study interval).

Main Outcomes and Measures

Measures of complexity included patient characteristics at the time of admission (eg, advanced age, multimorbidity, polypharmacy, recent hospitalization), features of the index hospitalization (eg, admission via the emergency department, multiple acute medical problems, use of intensive care, prolonged length of stay, in-hospital adverse events, in-hospital death), and 30-day outcomes after hospital discharge (eg, unplanned readmission, all-cause mortality). Logistic regression was used to estimate the relative change in each measure of complexity over the entire 15-year study interval.

Results

The final study cohort included 3 367 463 nonelective acute care hospital admissions occurring among 1 272 444 unique individuals (median [IQR] age, 66 [48-79] years; 49.1% female and 50.8% male individuals). Relative to the beginning of the study interval, inpatients at the end of the study interval were more likely to have been admitted via the emergency department (odds ratio [OR], 2.74; 95% CI, 2.71-2.77), to have multimorbidity (OR, 1.50; 95% CI, 1.47-1.53) and polypharmacy (OR, 1.82; 95% CI, 1.78-1.85) at presentation, to receive treatment for 5 or more acute medical issues (OR, 2.06; 95% CI, 2.02-2.09), and to experience an in-hospital adverse event (OR, 1.20; 95% CI, 1.19-1.22). The likelihood of an intensive care unit stay and of in-hospital death declined over the study interval (OR, 0.96; 95% CI, 0.95-0.97, and OR, 0.81; 95% CI, 0.80-0.83, respectively), but the risks of unplanned readmission and death in the 30 days after discharge increased (OR, 1.14; 95% CI, 1.12-1.16, and OR, 1.28; 95% CI, 1.25-1.31, respectively).

Conclusions and Relevance

By most measures, hospital inpatients have become more complex over time. Health system planning should account for these trends.

Evaluation of an Education-based Training Orientation for Resident Physicians in an Intensive Care Unit in Hawai'i

The need for multidisciplinary teams to provide complex care has increased as the population ages. As these teams become increasingly integrated, the knowledge, skills, and attitudes of resident physicians to practice safe and effective care in intensive care units (ICUs) evolves. A structured and multidisciplinary orientation day for resident physicians was implemented to assess improvements in physician confidence at Tripler Army Medical Center in Hawai'i from July 2019 to June 2020. ICU residents received an orientation day from a multidisciplinary team, with an emphasis on practical knowledge for common disease processes in a system-based fashion and competency in procedural skills. A total of 30 residents were asked to complete a pre- and post- orientation survey over a 1-year period, with 17 pre and post surveys completed for a response rate of 57%. The survey measured residents' perceived confidence in various tasks. Scores were compared using a paired 2-sampled t-test to assess statistical significance. The majority of resident physicians (76%) had at least 1 month of prior ICU experience. Statistically significant improvement was seen in self-reported abilities in performing 6 of the 10 elements assessed. With the diverse pathophysiology in critical care, it was essential to create a broad orientation with didactic and simulation-based learning, which resulted in observed improvement in more than half of the areas of interest. Adopting an orientation day for resident physicians rotating through the ICU can improve resident physician confidence, review important knowledge and skills, and highlight the role of each contributing multidisciplinary team member.

Anesthesia workforce capacity in Thailand: A multicenter study

Background

Workforce management in anesthesia services is crucial for service quality. However, the data associated with this are lacking. Therefore, this study was done to analyze workforce and workload and to compare differences among hospital clusters in Thailand.

Materials and Methods

We conducted a cross-sectional study in multilevel hospitals that were classified by location, the population cared for, and the categorization of physicians. Stratified randomization from all health service regions across Thailand was done. The profile of hospitals, number of anesthesia staffs, their capabilities, and ratio of anesthesia personnel to the service provided during the 5 workdays and 1 weekend period were analyzed.

Results

A total of 18 hospitals, ranging from secondary to super-tertiary referral centers, were included in the study. The mean number of personnel ranged from 2.0 ± 1.2 to 12.0 ± 0 for anesthesiologists and 7.5 ± 2.9 to 42.3 ± 19.3 for nurse anesthetists from each hospital cluster, which vary in terms of capabilities and the number of staff. The average number of anesthesia service units was 9.1 ± 4.2 to 31.9 ± 16.4, while the number of operating theaters was 6.9 ± 2.2 to 22.7 ± 8.3. However, the ratio of anesthesia personnel to one anesthesia service unit and the ratio of these personnel to an operating theater were not significantly different among the participating hospitals, with a mean of 0.94 ± 0.45 and 1.34 ± 0.38, respectively.

Conclusion

The overall number of anesthesia service units was above the designated operating theater capacity, while the ratio of anesthesiologists was 0.8-1.3 and nurse anesthetists was 2.4-6.5 per 100,000 people on an average, with a disproportionate responsibility ratio of anesthesia personnel to anesthesia service units during that time.

Huddles and their effectiveness at the frontlines of clinical care: a scoping review

BACKGROUND

Brief, stand-up meetings known as huddles may improve clinical care, but knowledge about huddle implementation and effectiveness at the frontlines is fragmented and setting specific. This work provides a comprehensive overview of huddles used in diverse health care settings, examines the empirical support for huddle effectiveness, and identifies knowledge gaps and opportunities for future research.

METHODS

A scoping review was completed by searching the databases PubMed, EBSCOhost, ProQuest, and OvidSP for studies published in English from inception to May 31, 2019. Eligible studies described huddles that (1) took place in a clinical or medical setting providing health care patient services, (2) included frontline staff members, (3) were used to improve care quality, and (4) were studied empirically. Two reviewers independently screened abstracts and full texts; seven reviewers independently abstracted data from full texts.

RESULTS

Of 2,185 identified studies, 158 met inclusion criteria. The majority (67.7%) of studies described huddles used to improve team communication, collaboration, and/or coordination. Huddles positively impacted team process outcomes in 67.7% of studies, including improvements in efficiency, process-based functioning, and communication across clinical roles (64.4%); situational awareness and staff perceptions of safety and safety climate (44.6%); and staff satisfaction and engagement (29.7%). Almost half of studies (44.3%) reported huddles positively impacting clinical care outcomes such as patients receiving timely and/or evidence-based assessments and care (31.4%); decreased medical errors and adverse drug events (24.3%); and decreased rates of other negative outcomes (20.0%).

DISCUSSION

Huddles involving frontline staff are an increasingly prevalent practice across diverse health care settings. Huddles are generally interdisciplinary and aimed at improving team communication, collaboration, and/or coordination. Data from the scoping review point to the effectiveness of huddles at improving work and team process outcomes and indicate the positive impact of huddles can extend beyond processes to include improvements in clinical outcomes.

STUDY REGISTRATION

This scoping review was registered with the Open Science Framework on 18 January 2019 ( https://osf.io/bdj2x/ ).

Determination of Clinical Parameters Sensitive to Functional Voice Disorders Applying Boosted Decision Stumps

BACKGROUND

Various voice assessment tools, such as questionnaires and aerodynamic voice characteristics, can be used to assess vocal function of individuals. However, not much is known about the best combinations of these parameters in identification of functional dysphonia in clinical settings.

METHODS

This study investigated six scores from clinically commonly used questionnaires and seven acoustic parameters. 514 females and 277 males were analyzed. The subjects were divided into three groups: one healthy group (N01) (49 females, 50 males) and two disordered groups with perceptually hoarse (FD23) (220 females, 96 males) and perceptually not hoarse (FD01) (245 females, 131 males) sounding voices. A tree stumps Adaboost approach was applied to find the subset of parameters that best separates the groups. Subsequently, it was determined if this parameter subset reflects treatment outcome for 120 female and 51 male patients by pairwise pre- and post-treatment comparisons of parameters.

RESULTS

The questionnaire "Voice-related-quality-of-Life" and three objective parameters ("maximum fundamental frequency", "maximum Intensity" and "Jitter Percent") were sufficient to separate the groups (accuracy ranging from 0.690 (FD01 vs. FD23, females) to 0.961 (N01 vs. FD23, females)). Our study suggests that a reduced parameter subset (4 out of 13) is sufficient to separate these three groups. All parameters reflected treatment outcome for patients with hoarse voices, Voice-related-quality-of-Life showed improvement for the not hoarse group (FD01).

CONCLUSION

Results show that single parameters are insufficient to separate voice disorders but a set of several well-chosen parameters is. These findings will help to optimize and reduce clinical assessment time.
